Exhaust household fans in the apartment. Bathroom hoods

In many houses and apartments, the bathroom and toilet are one unit. In such a space, it is absolutely necessary to install a ventilation system that will ensure the extraction of air that is unsuitable for being in a residential area. Today, in many bathrooms, owners are not satisfied with the standard hood installed when the house was built. Many install additional hoods that help get rid of excess moisture and unpleasant odors. Extractor to the bathroom - perfect solution for the bathroom.

Today, in many apartments, the bath and toilet are in the same space. On the one hand, it's convenient. On the other hand, it represents a number of problems that need to be solved once and for all. The solution to get rid of advanced level humidity and unpleasant odors can be the installation of a hood for the bathroom.

A bathroom equipped with a fan has a greater level of protection against the occurrence of fungus and the spread of mold, which is dangerous to human health.

When deciding to install a hood, it is important to familiarize yourself with the product options. They have different characteristics. Each device has its own characteristics, advantages and disadvantages. Designs can be natural or forced.

Design features:

• Natural. Works on the principle of difference temperature regime. The air flow is regulated by an air intake shaft. It provides an outflow of unnecessary gases and an inflow fresh air.
• Forced. Works thanks to the built-in electric fan. It is he who pumps streams of clean air and relieves the room of the accumulation of unclean gases.

All houses are equipped with natural ventilation, as it is included in the plan of a residential building. Since natural ventilation is subject to frequent clogging, the specialist is advised to without fail install forced ventilation. The choice of forced exhaust depends on the personal preferences of the owners of the premises.

Types of forced hoods

Ventilation devices must be reliable and productive, otherwise their installation will be a waste of time and money. To choose the right hood for the bathroom and toilet, you need to understand the types of ventilation systems. Many do not think about the fact that the presence of natural extract alone may not be enough.

Natural hoods are made with the expectation that they will cope with ridding the room of unpleasant odors by transferring temperature and changing air flows.

In many homes, natural hoods don't work and are a reservoir of extra dust and dirt. There are two main types of forced exhaust hoods that will help solve the problem of polluted bathroom air. The hood can be standard and automatic.

Hood types:

• Standard. Consists of an axial system equipped with check valve. It blocks the flow of unclean air into the room. The system turns on automatically when you turn on the light in the room. It should be noted that this type of hood cannot cope with large volumes of humid air.
• Automatic. The device has big power which affects its value. Such hoods are equipped with timers that can be set in accordance with the activity of using the bathroom.

When making a purchase, it is important to pay attention to the technical characteristics of the product. It is important that the manufacturer gives guarantees for the correct operation of the system. You can install the hood with your own hands, using ordinary tools or high-quality glue.

Tips for choosing an electric bathroom hood

The correct operation of the device always depends on the quality of its installation. The most important thing is to ensure that the shape of the hood matches the shape and size of the ventilation duct. After installation, only the decorative grille should remain outside.

When choosing and installing the hood, it is important to take into account a number of features and nuances that will allow you to install the hood so that it has served properly for many years.

The electric hood in the bathroom must be waterproof, as it will directly interact with moisture. It must also be protected from accidental ingress of foreign objects into it. The degree of protection can be determined by a special designation on the device.

What to look for:

• Security. The device must be reliably protected from direct water and steam jets.
• Performance. The hood must have a power that will help it cope with the volume of air. It, in turn, depends on the size of the room.
• Noise level. It is important to choose models that create little noise during operation, otherwise the hood will simply annoy and put pressure on the psyche.

After installation, the joints between the wall and the hood are best treated with a sealant. This will get rid of extraneous noise when the hood is actively working. Modern devices can be equipped with a humidity sensor, non-return valve, motion sensor, timer and silencer.

Extractor for a bathroom in a private house

The choice and installation of a hood for a private house is somewhat different. At the stage of building a house, it is necessary to take care of laying ventilation ducts and ducts for electrical wiring. It is especially important to take care of the installation of ventilation in a wooden house.

It is important to think in advance where the hood will be located, since the correct wiring depends on it.

The hood can be equipped with separate switches, or it can turn on simultaneously with the light. It should also be noted that some systems may run on batteries. Wiring is a critical step. If there is no self-confidence, it is better to entrust the work to a professional electrician.

Fan types:

• Combined with a fan. Flaw - a short time work, insufficient air purification.
• With a timer. Electric fans only work set time which is very convenient.
• Autonomous. They work independently of other electrical appliances. Automatic ventilation is considered the most convenient and practical.

The choice of fan depends on many factors. The main thing is that the exhaust fan works properly and has enough power to cope with the flow of humid and polluted air. You can choose the right fan only if you are familiar with the types of ventilation systems and their features.

When installing ventilation system important to pay attention to right place to install it. There is a wall and ceiling construction. If the fan is battery powered, then you don't have to worry about wiring.

The ventilation system requires careful and correct installation otherwise, the device may malfunction.

If confidence in own forces and there is no competence, professionals will help to do the installation correctly. At independent work It is also important to listen to the recommendations of professionals. It is better to carry out installation on initial stage repair.

Installation Tips:

• To connect the hood, it is best to use a light switch.
• For safety and beauty purposes, it is better to clean the wiring in strobes.
• After connecting the device, a plastic pipe can be inserted into the wall to protect the fan from external influences.
• If the ceiling height allows, the structure can be installed directly above the toilet. A complex exhaust structure will be more functional.

All stages of work must be carried out responsibly, since electric hoods pose a certain danger when interacting with humid environment. The hood should be located at a sufficiently safe distance from the bath. Properly installed bathroom and toilet hood prevent the accumulation of unpleasant odors and moisture.

Installing the hood in the bathroom (video)

If the natural exhaust does not work in the bathroom, installation can come to the rescue. forced ventilation. Present on the market today a large number of exhaust structures. They differ in their configuration, and, accordingly, functionality. You can install it yourself, following the advice of professionals. It is important to remember that when installing an electric hood, safety precautions must be observed. It is important to ensure that the hood does not clog, so it is better to choose a design with a damper.

room with high humidity is the bathroom, so you need to take special care when choosing a ventilation system.

Taking a bath creates steam from the water. As a result, condensation forms, which in turn leads to the formation of moldy walls, dampness, and a fungus appears.

The hood for the bathroom is selected powerful, which can supply from 26-51 cubic meters per hour of clean air. And in the presence of a bathroom from 51-101 cubic meters per hour.

Varieties of the hood and its characteristics

Before you start buying ventilation systems, you need to know what types of ventilation systems may exist. So, there are two types:

With natural ventilation. In this case, air flows are connected and move due to different pressure and temperature. This circulation can be achieved by open door, but in this case the humid air will not disappear.

Forced ventilation. This type hoods are efficient and involve the use of mechanical devices.

Thus, it is possible to install overhead or duct fans that are used if necessary, as a result of which the air in the room is updated.

But be aware that the fan only draws air from the bathroom, fresh air is supplied by open windows and doors.

Types of bathroom fans

As for the types of fans, there are only two of them:

• Axial fans.
• Centrifugal or in other words radial.

Axial fan consists of a wheel connected to a roller. The blade of the wheel is made at an angle. And the rotation is due to the motor. And due to this, air is drawn in, passing through the fan itself, and cool it.

Radial fan (centrifugal). It works according to this principle, air is sucked in the center of the device and enters the casings with blades.

Their location is such that a vacuum occurs there, and due to centrifugal force, the air is beaten off from the center to the edges and exits through a passage on the side wall. This type of fan is more efficient and less noisy.

What to look for when choosing a fan?

So the room with high humidity this is a bathroom, then manufacturers began to make appliances capable of working under such conditions. Since the fans are connected to the mains, you need to make sure that the case is sealed and waterproof.

There are standards that ensure the reliability of electrical mechanisms. They are designated IP, and have two digits.

The level of protection against ingress of third-party elements and particles is shown by the first digit, the second level of protection against moisture. For the bathroom, you need to choose from level 4.

With the device for ventilation comes a certificate where this level is indicated. It is better to take fans with IP -34 and more.

There is a list of parameters that you need to pay attention to when choosing a fan, and how they look can be seen in the photo of bathroom hoods:

performance and power. The higher the power, the better the performance will be. If there is a very powerful fan, then a draft will appear from it, as a result of which the room will not warm up, and it will also make a lot of noise.

The presence of a timer. On a simple fan, the control is mechanical. You can turn it on and off as needed.

In the presence of a timer, it turns into a semi-automatic. The bathroom hood with a timer continues to work even after the person has left, and after a while it turns off on its own.

The presence of a moisture sensor. This is very convenient, because when a certain level of moisture is reached, the sensor turns on by itself, this is a plus. electric hood For bathroom.

Diameter. Before purchasing a fan, you need to take measurements. Usually they range from 10 to 13 cm.

Extract for a bathroom with the valve. The presence of a check valve is one of the important elements, bathroom hoods with a non-return valve, especially for a city bathroom that is connected to a common ventilation system. It will prevent foreign odors from other apartments from getting into your apartment.

It is also worth paying attention to appearance fan. Now there is so much variety color solutions that you can choose for almost any interior.

Installing a hood for the bathroom and toilet

• You can install the hood as follows:
• By placing the case so that it is completely in the exhaust duct;
• The second option is to place the case overhead on a wall or ceiling;

• Depending on the surface material for fastening, use self-tapping screws, liquid nails, dowels.
• To reduce noise from work, use sealants.

• Soft rubber will not be superfluous in the channel hole. But this is up to you.
• As for the power supply, it must be placed in special channels and a corrugated casing. open and insulated wires shouldn't be at all.

And so, you saw that it is very easy to solve the problem with high humidity and odors. The installation process of the fan is not complicated, and does not take much time.

But as a result, you will get a comfortable indoor climate.

Photo of bathroom hoods

When building a private house, there are no trifles. The question of how an exhaust hood should be made in a bathroom in a private house is quite complicated. But it is necessary to solve it if then there is no desire to breathe stale air and unsuccessfully fight black spots of mold on the walls.

The bathroom is one of the wettest places in the house. After acceptance water procedures a large amount of steam is formed in the air, which settles in the form of condensate on all surfaces - the ceiling, walls, mirrors, plumbing and furniture.

If there is no normally working one, then the accumulated moisture begins to spoil, promote the formation bad smell and mold formation. Therefore, the question of how to make a hood in the bathroom should be a priority.

Ventilation in the house can be either natural or forced. The choice of the type of ventilation system depends on the specific conditions in the house.

natural ventilation

As a rule, this type of ventilation is laid down at the stage of creating a project. To do this, ventilation ducts are provided in the bathroom and other rooms that lead to the attic.

As a rule, ventilation ducts are laid out with bricks or ready-made plastic pipes are used to create them.

Here are a few tips to help get the job done if you plan on a natural bathroom hood.

• It is better to plan air ducts vertically, at the same time, each air duct is used for one room.
• It is allowed to combine extracts from the kitchen and sauna, from the bathroom and toilet into one channel, provided that the premises are located on the same floor.
• In the attic, it is allowed to combine hoods from all the listed rooms into one channel. But if, according to the project, ventilated rooms are located on different sides of the house, it is not recommended to combine them in the attic.
• Since natural exhaust systems for the bathroom are low pressure, internal surfaces air ducts should be made as smooth as possible; when installing them, it is recommended to avoid sharp turns and the formation of protrusions.

If the creation of a bend in the duct cannot be avoided, then it must be made smooth, with a turning radius of at least 10 cm.

• If the building is one-story, then an example of the use of forced ventilation in the bathroom in the ceiling is often mounted, in this case the air is removed from the room through the attic to the roof.

Forced ventilation

A forced ventilation device is necessary if:

• When the hood in the bathroom does not work on natural draft or its work is not effective.

• When the previously working system natural ventilation out of order, and its repair does not seem appropriate.
• If it is planned to install a steam generator or an electric sauna in the bathroom.

As a rule, in this case, an exhaust fan is installed for the bathroom - various models of hoods are available for the bathroom.

They differ in size and shape, but the principle of their work is the same. The hood consists of an electric fan and a piping system for air extraction.

About bathroom fans

What range of fans exhaust ventilation worth buying when installing a ventilation system? As a rule, these are axial models that can remove from 60 to 250 cubic meters of air per hour from the room.

To determine the required power of the model, use the simplest formula:

M = V * (5…10),

in this formula, the symbol M indicates the performance required to ensure normal air exchange in the room. The symbol V indicates the volume of the room in cubic meters, and the numbers in brackets are a correction factor that depends on the frequency of use of the bathroom.

Example: Let's calculate required performance, which must have Installing a protective mesh on the ventilation duct, in a house where the bathroom has dimensions of 2 x 1.5 x 2.5 meters. First, let's calculate the volume of the room, in our case it will be equal to 7.5 cubic meters. (2*1,5*2,5 = 7,5).

If the house is inhabited by one person who uses the bathroom twice a day, then a minimum correction factor of five can be taken. As a result, the minimum productivity should be equal to 5 * 7.5 = 37.5 cubic meters.

Is it safe to install an electrical appliance in the bathroom, because the humidity is high there? For such premises, a special class of devices with a high class of protection is produced. They are marked with the letters IP and numbers. The larger the number, the higher the protection class of the device.

If an extractor hood is installed in the bathroom, then a gap under the door for air flow should be provided. In the absence of such a gap, the efficiency of the device is reduced to zero.

Modern hoods in the bathroom are equipped with automation. These are motion sensors that turn on the system only if there is someone in the room.

Humidity sensors are also convenient, which detect the presence of water vapor in the air and, with an increase in its amount, turn on the system automatically. Sometimes systems are equipped with timers that allow you to set the fan operation time.

All these devices allow rational use of energy resources.

A bathroom hood with a non-return valve is very convenient, this is a system that does not allow air from other rooms to enter ventilated rooms, which is important for multi-storey buildings, as well as dust and debris from the street.

As for the noise during ventilation, you should not believe the advertising promises, absolutely silent models do not currently exist. However modern hoods operate quietly enough not to cause irritation.

To reduce the noise level from a running fan, you can put a special device right behind the unit - a silencer, as well as finish upper part ventilation shaft with soundproofing material.

How to install a hood in the bathroom?

So, the fan is selected, now the installation of the hood in the bathroom must be made. It is not difficult to do this, although if a person has never dealt with electrical circuits and does not know which side to take on a screwdriver, then this work should be entrusted to professionals.

For home masters who are confident in their abilities, you can give the following advice:

To reduce the noise level and provide additional sealing, a layer of silicone sealant should be laid between the base of the hood and the wall.

• The fan must be connected to the mains, it is recommended to install a separate switch to turn it on.
  Some owners connect the hood to the same switch that turns on the lighting, but this is not always rational, so it is better to put a switch with two keys.
• At the last stage of installation, the fan is closed with a ventilation grill, which is fixed with latches or self-tapping screws.

Findings:

Thus, the installation of forced ventilation in bathrooms helps to solve the actual problem of ventilation of the room. A window is rarely planned in bathrooms, so the only way to establish normal air exchange in the room is to organize effective system ventilation.

Usage modern systems automation makes the use of hoods very convenient and helps to rationally use energy resources.

The bathroom is characterized by high humidity. The steam condenses on the ceiling and walls, leading to the formation of fungus and mold. To prevent these processes, it is necessary to responsibly approach the issues of arranging ventilation and selecting exhaust fan.

Quality hood the bathroom should be supplied from 25 m 3 / h of fresh air for a separate room, from 50 m 3 in the case of a combined bathroom.

Modern hoods designed for installation in the bathroom are conventionally divided into 2 types: simple and automatic. They differ from each other in design, availability of additional options and cost.

Simple equipment is an electric fan, which is located in a tubular plastic case. It can be of two types - built-in or freestanding.

Automatic exhaust devices are easier to operate and require minimal participation of the owner of the premises in the process of controlling air exchange.

A popular way to turn on the unit is by pressing the switch that provides the bathroom lighting. This option allows the removal of polluted air from the bathroom occurs when a person is in it.

Automatic equipment is equipped with electronics that effectively control the operation of the device.

For a short period, moisture does not have time to completely evaporate from the room, so it is better to install a separate switch

Hoods are equipped with additional functions:

• off timer;
• humidity sensors;
• colored backlight.

The fan turns on when the allowable value humidity. As soon as this parameter returns to normal, the device turns off.

Automatic models are convenient and easy-to-use devices that do not require the intervention of the owner of the apartment to control the operation of the ventilation system.

Automatic products can be equipped with other functions. In private houses, the ventilation system borders on the street, so their owners will not be harmed by a fan with an adjustable diffuser.

Some models are equipped with a check valve that prevents air from moving in the opposite direction. This option is useful for residents of apartments in high-rise buildings to protect themselves from the aromas of a neighbor's bathroom.

Despite the simplicity of the design exhaust system for the bathroom, it functions perfectly and copes with its tasks

Modern hood designed for installation in the bathroom, has coercive principle actions. The device consists of a fan and an air duct connected to the ventilation duct of the building.

The axial exhaust fan has a relatively simple design, which does not affect the functionality of the device. In terms of performance, it can compete with air conditioners.

To pick up optimum extraction, it is necessary to take into account the features of the bathroom and the varieties of existing ventilation systems. Devices may differ in design, principle of operation, power and availability additional features.

Types of ventilation in the bathroom

Natural or forced ventilation can be used to ensure air exchange in an enclosed space. The first option does not require the use of special equipment that performs certain functions.

The second involves the use of fans, air heaters, motors, air-cooling devices and other accessories.

Natural air renewal option

The air flows are mixed, and then shifted due to various temperature and pressure indicators. You can create free circulation by opening the door. But in this case, part of the moist air will remain in the room.

In high-rise buildings, a ventilation shaft serves all apartments in a riser. The entrance to it is closed with a grate, and the cleaning efficiency depends on the general condition. In suburban buildings, ventilation ducts are removed even at the construction stage.

In the process of installing a natural hood, the following rules must be followed:

1. The grate in the bathroom / WC should be located in the upper part of the room - on the wall or in the ceiling.
2. The inner surface of the pipes must be perfectly smooth.
3. The protrusions and turns of the duct reduce the circulation efficiency by 5%.

Natural ventilation is considered not very effective, for this reason it is rarely used in apartment buildings. residential buildings. More often it is used in suburban buildings used for seasonal living, for example, as a summer residence.

More often, natural ventilation gives the desired result due to the pressure difference between the window and the door. The tightness of the doors interferes with the operation of the ventilation duct

Features of forced ventilation

In the bathroom, mechanical evacuation of exhaust air using mechanical devices is more often used. This may be an invoice or duct fan. It turns on when needed and creates traction.

In private buildings, channels are often installed that bring out the spent air flow through the attic of the house. The fan is designed for effective exhaust polluted air, and fresh air can enter the bathroom through an open door.

Compact forced ventilation takes up a minimum of space in the room, but it is enough to effectively ventilate the bathroom

Types of indoor fans

There are 2 types of equipment used in bathrooms, toilets and shared bathrooms. These are axial and radial exhaust devices. The latter are also called centrifugal.

Axial devices are a shaft on which a classic impeller is mounted. Its blades are made at an angle. When the shaft rotates, the air flow is drawn in. Such a fan is used if the pressure generated by it is sufficient to ensure normal air exchange.

Buying a household axial fan - rational solution for owners of apartments and private houses. It allows you to create indoor comfortable environment with minimum investment

In radial devices, the air flow is drawn into the center, after which it ends up in a casing with blades. Due to their location in the central part, rarefaction is observed, and centrifugal force repels air masses to the edges of the housing, which are discharged through the outlet pipe into the ventilation duct.

Overhead models are most in demand - they work much more efficiently and quietly, they are able to evacuate volumes that are beyond the power of axial ones.

According to the degree of completeness, fans of the centrifugal principle of operation are divided into basic and with additional options . The second can work in automatic mode.

Automatic centrifugal products are additionally equipped with a timer and sensors. They allow the owner of the premises to control the operation of the equipment.

The main parameters of the hood for the bath

The specifics of the bathroom prompted developers to produce appliances adapted to rooms with high humidity. The case of a fan powered by electricity must be airtight. The internal design of the equipment is reliably protected from all sides from the effects of wet steam.

Attention to the characteristics of the device

For consumers, the International Electrotechnical Commission has developed a certain reliability standard electronic devices. It is denoted by IP and consists of two digits. The value of the first can be from 0 to 6 and indicates the degree of protection against the penetration of impurities.

The second digit defines moisture protection level. To use the product in the bathroom, the indicator should be at least 4.

Each product must have a certificate that determines the level of its safety. For the bathroom, it is better to choose a device whose IP is greater than 34

Power and performance are closely related. The higher the first indicator, the greater the second will be. You can find out the performance indicator by multiplying the footage of the bathroom by the number of people living in the house.

If the fan is equipped with many additional functions, its power can be up to 10% higher than the calculated one. The most popular are economical and almost silent devices that consume from 7 to 20 watts.

When devices with a high power indicator are operating, a draft is observed in the room, and besides, it will not be able to warm up enough.

Another one important characteristic- the level of noise that the blades of the device create during operation. It is much quieter than in operation. kitchen hood. The norm acceptable for an exhaust device is considered to be a sound of 30 dB or less. This is due to the fact that a person perceives all sounds above 35 dB as unpleasant and intrusive.

Timer, humidistat, non-return valve

Standard bathroom ventilation devices are mechanically controlled or operate in slow, continuous mode. The timer is an additional device that allows you to half automate the process.

After the person left the bathroom, the fan, thanks to the timer, continues to evacuate the exhaust air for some more time. Upon completion, it turns itself off.

Smoky air, steam fumes and smells of food being prepared in the kitchen do not favor a normal microclimate in an apartment or house. To solve this problem, it is recommended to install hoods in the bathroom and in the kitchen.

The presence of a humidity sensor is best option For bathroom. Hygrometer considered best method control, as it allows you to set the humidity threshold from 40 to 100%, upon reaching which the fan automatically turns on. The hygrostat and timer are rarely used together. Usually, if a humidity sensor is present, a timer is not required.

With ventilation equipment in country house it is necessary to measure the hole in the bathroom or in the bathroom, which will determine the diameter of the duct. The standard landing size of the hood is from 100 to 130 mm. If necessary, the hole in the bathroom wall can be enlarged using a perforator.

The best option to ensure normal air exchange and a comfortable indoor climate is to choose a ventilation device of the required size

The non-return valve is a small and simple device that will prevent unpleasant odors from neighbors from entering the territory of your apartment. It is practically indispensable in urban baths and bathrooms connected to a common ventilation duct.

How to choose the right device?

When arranging the ventilation system in the bathroom, you will need to choose an exhaust device. First of all, you need to determine its capabilities, which consist in the ability to drive a specific volume of air. This indicator depends on the diameter of the device.

Manufacturers offer devices with a pipe section of 80, 100, 120, 150 mm. For Khrushchev, the diameter of 80 mm or 100 mm will be optimal. In new buildings, apartments have an improved layout; here it is better to stop at a section of 120 mm.

Another important factor is appearance. Many manufacturers produce hoods with a removable outer panel. Fans from Elicent, Electrolux, Ballu, Timberk and other brands come in a variety of colors and shades.

The advantages of hood models with a removable panel are the ease of maintenance of the appliance and the ability to realize bold design ideas.

An attractive and stylish appliance can be made an accent element of the interior or fit it so that it is not conspicuous.

When choosing, it should be borne in mind that water should not come into contact with electricity - the fan will have to work in conditions of high humidity. To avoid trouble with wiring, experts recommend using a product designed for long-term operation in such premises.

It would be useful to check the noise indicators of the device - superfluous and unpleasant sounds play the role of an auditory stimulus. When a high-quality fan in the bathroom is running, it is almost silent.

When you turn on the silent exhaust device, you can hear a little movement of air that occurs in the pipe of the appliance body

It is also worth paying attention to the strength and reliability of the device. A small number of companies specializing in the production of bathroom fans can guarantee that their products will work for several years. O high quality indicates the warranty period from the manufacturer. If it is less than 1 year, it is better not to buy this device.

Preparing a site for an exhaust fan

Before installation, a series of preparatory work. First of all, you need to check how well it works ventilation duct by bringing a lit match or candle to the inlet. The flame should tilt at an angle towards the grate.

If a lit flame indicates that the ventilation duct is clogged, urgent action must be taken and the device cleaned before installing the hood

If the diameter of the ventilation duct opening is larger than the fan section, then you can insert a plastic or corrugated pipe of the desired diameter, and close the voids mounting foam cutting off the excess sharp knife after setting the solution.

If the hole at the entrance to the mine has a smaller diameter, it is expanded with a perforator.

Choosing the optimal connection scheme

Before installing any model of exhaust fan in the bathroom, you need to decide how it will be connected to the power source.

Today there are different ways exhaust connections:

1. The switch is located on the body of the device. In this case, it can be turned on or off using a button or a cord located on the case.
2. Connecting the device to a separate switch. A switch is installed in front of the bathroom, in which one of the keys turns on the ventilation, and the second turns on the lighting.
3. Automatic fan activation by humidity or motion sensor. It starts functioning if exceeded allowable level humidity or movement appears.
4. The device is connected to a light switch. It can be equipped with a timer and connected in parallel with the luminaire. It turns on simultaneously with the lighting and turns off when the light is turned off.

The latter method of connecting the device is less in demand, since apartment residents often go into the bathroom for a short time to quickly wash their hands, brush their teeth or wash their face. In these cases, the switched on hood will waste energy in vain.

The scheme for connecting ventilation to a light switch is used quite rarely, since for most people a working fan prevents them from relaxing and taking a bath

Lay wiring for better under the tile. If this is not possible, then you can mask the cable using special plastic boxes.

The procedure for carrying out installation work

Before connecting a fan in the bathroom, you should read the instructions that describe detailed process installation. In accordance with the recommendations, the selected model of the hood is installed in the bathroom or in the bathroom.

Actions are performed in a certain sequence:

1. First, remove the front cover and apply liquid nails, silicone or polymer glue to all areas where the product adjoins the wall surface. These materials will provide strong fastening of relatively light plastic.
2. We insert the device so that the working part, together with the electric motor, is completely in the wall. Press firmly to the attachment point for a few minutes.
3. We put a mosquito net that will not allow various insects and midges to enter the room.
4. We attach the front cover with the screws that are included in the kit. this action is carried out last.

When connecting to the power supply, there should be no open wires without insulation in the room. They are placed in recessed ventilation ducts using a corrugated casing.

When connecting the hood to the power supply, safety precautions must be observed. First of all, you need to make sure that the electricity in the room is turned off. To connect the wires, not twists are used, but more reliable terminal blocks

Many users connect fans through a contact pair to a light switch. The switch is set to phase.

For convenience when using the device in the future, you can put a separate key to turn on the hood. If when visiting the bathroom there is no need for its operation, then it is convenient to use only the lighting control key. then the time spent in the room will not be overshadowed by the hum of rotating blades.

Conclusions and useful video on the topic

Video #1 how to choose equipment and organize everything correctly:

Video # 2 why you need a bathroom hood and how to install it:

The hood allows you to get rid of high humidity in the bathroom and eliminate odors that penetrate the room. This is a popular and inexpensive equipment, characterized by ease of installation. Popular fan models are produced by manufacturers Ballu, Timberk, Elicent, Electrolux and others.

Despite the fact that installation work will not take much effort, money and time, the device will become indispensable assistant in the fight for clean air and a comfortable microclimate.

In the bathroom and toilet, condensation forms more strongly than in other rooms, and unpleasant odors appear. Therefore, here arrangement proper ventilation really necessary. A high-quality hood contributes to the normalization of the indoor microclimate, ensures its compliance with sanitary and hygienic standards and requirements.

Ventilation in the bathroom and toilet avoids the appearance of dampness and fungus. This contributes to the normal well-being of people living in the house. Finishing, plumbing, furniture, which is located in such premises, will last much longer. All work can be done independently. For this, you need to familiarize yourself with existing rules creating ventilation in the toilet and bathroom.

Ventilation Requirements

Proper ventilation in the bathroom and toilet is one of the important factors that allow you to fully exploit the premises. It is as important as heating, lighting and water supply. The quality of the equipped ventilation depends on the compliance of the oxygen environment inside the dwelling with the existing requirements.

The bathroom and toilet are enclosed, poorly ventilated areas. Here there is an increased probability of reproduction of pathogenic bacteria and fungi. SNiP establishes air exchange indicators. Its intensity per hour should be 25 m³ for the bathroom. The air flow per hour for a combined bathroom should be 50 m³.

To check the operation of the hood, you need to bring a burning match to the ventilation grill. If the flame is not drawn in by the channel, then the ventilation in the bathroom and toilet is not functioning. AT high-rise buildings old sample, such a picture is observed due to clogging of the channel. If a similar problem is detected in a new house, then the system was designed incorrectly.

The best solution to the problem would be the arrangement of a new forced ventilation. Such a system has many advantages over passive exhaust. It is able to quickly solve the problem of dampness and the appearance of fungus, an unpleasant odor in such rooms.

Air exchange type

Ventilation in the bathroom and toilet, which options are offered to property owners today, can be natural and artificial. In ordinary high-rise buildings built in the last century, the first type of systems is used. From windows and doors, fresh air in this case enters the room. Then it exits through the ventilation ducts.

The movement of air masses during natural ventilation is achieved due to the pressure difference between indoors and outdoors. AT modern apartments windows and doors are different high rates tightness. This disrupts the natural circulation of air in the room. Therefore, acquiring new plastic windows and hermetic doors, provision should be made for the presence of devices for ventilation in them.

Forced or artificial ventilation requires special equipment. It is built into the air exchange system. There are a large number of different fans for forced ventilation. They relieve pressure inside the bathroom and toilet. Air is pulled out. This process leads to the flow of oxygen into these rooms from other rooms.

The arrangement of forced exhaust in the bathroom can solve the problem of inefficient natural ventilation. It requires more time and cost during installation. Over time, the effort spent is fully compensated. All interior items and decoration in such rooms last much longer than with a natural type of air exchange. Human health will not be threatened by various pathogenic microorganisms. Therefore, forced extraction is preferable today.

Types of ventilation

Sanitary and hygienic and building codes argue that forced ventilation in the bathroom and toilet is preferable. However, it should be noted that there are several other features by which such systems are distinguished.

According to the purpose, supply, exhaust and mixed ventilation are distinguished. In the first case optional equipment provides fresh air to the room. This creates overpressure. It forces the old air masses to leave the room through the outlet ventilation ducts.

The exhaust type of the system provides for the presence of a fan directly on the channel shaft. In some cases, it applies combined method. It assumes both types of arrangement of systems.

Ventilation also differs in design. There is a channel and channelless hood. The second option involves the movement of air masses through equipped holes in the walls between rooms. For example, it can be the ventilation of the bathroom through the toilet or vice versa. In one of these rooms there is an exit to the exhaust shaft common throughout the house. Air from the second room first enters the first room through a hole in the wall, and after that the mixed masses leave the apartment through the channel.

However, duct ventilation is more efficient. It involves bringing the exhaust shaft directly to rooms with high humidity. This ensures complete air exchange in the bathroom.

Fan type

Forced ventilation in the bathroom and toilet involves the use of additional equipment. It may vary in installation method and design. Fans provide sufficient air exchange rate for combined and separate bathrooms.

According to the installation method, equipment of radial and channel type is distinguished. In the first case, the fan is mounted at the shaft outlet. Its body has an aesthetic body. Channel varieties are installed directly in the mine itself.

According to the type of design, a diametrical, axial, centrifugal and centrifugal-axial fan is distinguished. In the first version, the product has a drum-type impeller. This design has a low efficiency. An axial fan pumps air through the blades. Such equipment is applicable for ductless ventilation.

The centrifugal fan has a spiral housing. This is the most productive, but also the noisiest equipment. The centrifugal axial fan has the highest performance. It is compact, efficient and has a low noise level. Today, equipment has appeared on sale in which humidity sensors are built in, a timer. This allows you to ventilate the room as efficiently as possible.

ventilation duct

There are certain requirements on how to do it (ventilation in the bathroom and toilet with your own hands must be carried out with high accuracy) correct system. They must be considered before starting work.

The ventilation duct in a private house works simply. He joins special equipment or displayed on the roof. This is an easy job. The creation of the project must be completed at the stage of preparation for the construction of the building.

The most high-quality ventilation obtained in houses from natural wood. This is due to the ability of the material to "breathe". In this case, it will be enough to equip natural ventilation. The construction of logs and timber is considered not only beautiful, but also practical.

Owners of apartments in multi-storey buildings need to devote more time and attention to the arrangement of ventilation. All apartments in the entrance communicate with a common shaft, through which the air leaves the house to the street. If, for example, a bath and a toilet are one room (there is no forced ventilation), according to the norms of SNiP, air exchange per hour in the amount of 50 m³ is required. The higher the apartment is in the house, the more likely it is that this indicator will meet the established level.

Over time, the channels apartment buildings get clogged. If they have not been cleaned for a long time, air exchange during natural ventilation is difficult. The lower the apartment is in the house, the worse the hood is. In this case, the installation of forced ventilation is simply necessary.

Fan power

To understand how to do (ventilation in the bathroom and toilet forced type- one of options in this case) the hood in the bathroom, you should consider the basic requirements for creating such a system. In this case, it is planned to install an electric small-sized fan. This device must be secure. It should not fail if steam or water enters the structural elements. You should also pay attention to the noise level of the fan. He should not annoy the owners of the house.

Particular attention is paid to the choice of equipment power. This indicator is influenced by the dimensions of the bathroom and the number of people permanently residing in the house. For calculations, it is necessary to calculate the area of ​​\u200b\u200bthe bathroom and toilet. Further, the result is multiplied by 6 if the number of users does not exceed 3 people. If there are 4 or more people in the family, then the dimensions of the bathroom are multiplied by 8. The result will be optimal power fan.

Fan installation rules

Do-it-yourself ventilation in the bathroom and toilet requires correct installation all elements of the system. There are several requirements for the location of equipment in the room.

The ventilation duct should be at the maximum height, preferably under the ceiling. It should also be located as far as possible from the source of air inflow in the bathroom. If this requirement is not met, only part of the room will be ventilated.

For forced ventilation, it is important to install the fan away from the water source. This will prevent accidental splashes.

If there is no ventilation in the room, and the exhaust duct is located in an adjacent room, it will be necessary to provide for the installation of additional ducts and pipelines. There are rigid plastic and movable corrugated structures.

Mounting methods

Most often, ventilation in the bathroom and toilet does not require the construction of additional air ducts. It is enough to install the selected fan at the entrance to the mine. In this case, the common exhaust duct should be located immediately behind the wall of the bathroom or shared bathroom.

It happens that the ventilation duct shaft is located behind the wall in the toilet. If it is separated from the bathroom by a partition, a hole can be made through it. Walls are installed on both sides ventilation grates. This will be quite enough to create the required air exchange.

If there is access to the shaft both in the toilet and in the bathroom, separate ventilation should be made for each room.

One of the most effective approaches is the installation of gratings with slots at the entrance to the mine for the installation of forced ventilation equipment. In this case, the natural and intensive systems are combined.

Preparing for installation

At the renovation planning stage, a project is created in which ventilation in the bathroom and toilet is thought out. The advice of experienced builders will allow you to prepare and install correctly. Planning will allow you to hide the wires under the walls, calculate the required characteristics of the equipment, as well as the location of all elements of the system.

If ventilation is created in a multi-storey apartment building, you should be responsible for cleaning the mine channel. If the property owners live on the upper floors, you can do this work yourself. On the roof is the exit of the exhaust shaft. You need to lower the weight into it. If the owners of the apartment live on the lower floors, it will not be possible to do without the help of representatives of the Housing Office or special services.

In a private house, it will be easier to clean the ventilation duct. Over time, dirt, cobwebs, debris from the roof, etc. accumulate here too. necessary elements system, you can proceed with the installation.

Fan mounting

Do-it-yourself ventilation in the bathroom and toilet is easy to install. First, to the equipment of the forced type of the system, electrical wire. It is selected in accordance with the selected fan power. Also, such conductors must have a high insulation class.

The fan is installed in a place prepared for it. It is attached with self-tapping screws. The grid is also installed using a special fastening material. This will eventually unscrew the grate and clean it from contamination.

If an additional ventilation duct is being arranged inside the room, it is possible to sew up the pipes under the ceiling with drywall. So the appearance of the room will be aesthetic.

Having considered what ventilation is in the bathroom and toilet, as well as the rules for its installation, each owner of an apartment or a private house will be able to create a complete system in the bathroom on their own.
