A toilet is a part of an apartment and a house where high-quality ventilation equipment is not a luxury, but a real necessity. In almost any case, this room in the dwellings does not have any windows, as a result of which fresh air practically does not enter there. As a result, excess moisture and odors will constantly accumulate there. This, in turn, will lead to the formation of fungi, mold on the walls.
It is to solve such problems that the hood in the toilet is designed. By installing such a device there, it will be possible to successfully solve the above problems, maintaining the indoor microclimate at a comfortable level.
Ventilation toilet and its types
All existing types of bathroom ventilation in the apartment are divided into two types:
- natural;
- forced.
Even at the stage of building a house, the mines of the ventilation system are laid in it, which pass throughout the house. Their main purpose is to ensure the influx of fresh air into the house and the removal of exhaust from it. This is natural ventilation. But it is usually not enough to provide a good microclimate. Therefore, ventilation in the toilet and other parts of the house is enhanced by installing a special hood - this is a forced ventilation system.
Such a device has a special box, which is most often installed directly in the shaft of the system.
The use of the hood allows you to ensure high-quality and quick output of exhaust air along with moisture from the bathroom.
Features of using the fan in the toilet
The bathroom differs from the rest of the rooms in the house primarily in that it is visited only periodically and for a short time. Therefore, the hood should work only for a short time. The optimal duration can easily be determined experimentally. It is worth considering that in the summer the device will need a little more time to cope with its duties. Having determined the right time and having bought a hood with a timer, it will be possible to achieve optimal and effective functioning of the device with low material costs.
It will also be useful to use the built-in check valve, which will help with the sudden occurrence of back draft.
A variety of appliances: what to look for
The household appliances market currently offers everyone a variety of different models of hoods for use in the toilet of an apartment. Each has its own equipment, power level, functionality and other features. How to make the right choice? To do this, you just need to pay attention to the most important characteristics:
- safety in use;
- performance level;
- noise during operation.
The hood in the toilet is primarily equipped with reliable protection against moisture inside the device. If this is not the case, penetration of moisture will cause a short circuit, which is likely to lead to damage to the wiring.
Therefore, you should choose models with a good level of protection against such influences and a voltage level of 24 V.
The performance level of the hood in the bathroom in the apartment is also an important indicator, which is important to consider in the selection process.
To calculate the optimal level of this indicator, there is a special formula. You need to multiply the volume of the room by the multiplicity of the exchange of the air mixture.This indicator is determined by building codes for each type of room in the house, for a toilet the multiplicity is from 6 to 9.
Having obtained the necessary performance indicator, it is recommended to choose a device with a certain margin so that the device does not constantly work at the limit of its capabilities.
Most often on sale there are models of hoods with a fan, the productivity of which is 100 cubic meters per hour. For the toilet this will be enough.
Any device for forced ventilation during its operation is noisy - the noise can be mechanical or aerodynamic. The second type arises as a result of the vibrations of the duct, the first is the result of the operation of the exhaust motor.
The normal noise level is 25 dB, you can find this figure in the instructions for the specific model. If your favorite hood has a higher noise level, it can be reduced by installing special noise absorbers.
Installation steps
It is quite simple to carry out independent installation of the hood in the toilet, especially if the fan is simply mounted in the finished hole in the system.
Such work is carried out in several stages.
Site preparation
First of all, it is necessary to carefully prepare for installation the place where the hood will be located. If necessary, the channel where the installation will be carried out is expanded to the desired size. If the channel, on the contrary, is larger in size, it will be necessary to select a corrugation or pipe of exactly the same diameter, and already install the device in it. All cracks that remain at the end of this stage are carefully sealed with foam.
Fan installation
After completing the preparation of the place, the next stage begins - the installation of the ventilation device. Where it will be located, silicone or glue is applied to the wall, then the fan is pressed tightly against the wall for some time. After that, the front cover of the fan is fastened with screws.
Electrical cable routing
To ensure the hood is electrified, you will need to run the cable exactly to the place where the device will be located. It will be good if the hood is installed during the overhaul - in this case, it will be possible to hide the cable in the channel under the finishing material. If such work has long been completed, the cable will have to be hidden in a box.
If there are several switches in the room or if the ventilation in the bathroom is combined with the bathroom, it is better to resort to the services of professionals, since such works are quite complicated, special skills and tools are required.
Installation tips
When you independently install the hood in the bathroom, you definitely need to familiarize yourself with some important points of such work, otherwise the hood will not be able to function with maximum utility.
The most important tips for the proper installation of an exhaust device are:
- Installation of the hood must be carried out as high as possible, best of all - right under the ceiling;
- The device should be placed away from the source of moisture, otherwise a short circuit may occur at some point;
- For maximum functionality, the hood should be located exactly opposite the doors, which will ensure the prompt flow of fresh air after the exhaust;
- You can not install the hood on the same wall as the doorway - in this case, the air flow will be very weakened;
- With the correct installation of the hood, its body must be completely hidden inside the ventilation shaft. From above, only the grill will be visible, ensuring the decorativeness of the ventilation hole;
- To reduce the noise level during the operation of the hood, you will need to install a special silicone gasket. It must be located between the device and the wall;
- To provide power to the hood, there are two ways to connect it - along with lighting the room or with a separate switch.
When choosing the first option, remember that when the lighting is off, ventilation will not function. It is clear that this is completely inconvenient, so it is better to use the second option when the hood is equipped with its own switch.
Hoods with extra features
In the case of providing a separate switch for the hood, it will be possible to purchase models that are equipped with additional functions, which make its use more convenient. The most popular among them are:
- exhaust hood with check valve. In this case, air from the mine will never get into the room. This is especially true in apartment buildings, where there will be no smells from neighbors;
- Motion Sensor. Such a model will be turned on when a person enters the toilet and turns off when he leaves the bathroom;
- timer. In this case, it will be possible to turn on the device for operation for a certain time;
- humidity sensor. In this case, when a certain humidity level is reached, the fan will turn on and off on its own when this parameter returns to its normal level;
- regular ventilation mode. Such models are constantly working at minimum speed. If the humidity rises significantly - the maximum mode of operation is turned on.
Often on sale you can find models that are equipped with several of the above functions, for example, an exhaust hood for a toilet with a non-return valve, a timer and a humidity sensor.
If the house has a separate bathroom, then in this case it will be possible to use one fan at once in two rooms at the same time, simply connecting them with a regular corrugated pipe. In this case, the operation of one hood will provide ventilation of two rooms at once.
Do you want the air in the toilet of your home to never stagnate and always remain fresh, and the work of a natural-type air-cleaning system is not enough for this? There is a solution - it’s quite simple to purchase and install a hood with a built-in fan for this room. Having checked the functionality of the ventilation ducts and even installed a simple fan, the microclimate in the bathroom will forever become comfortable and pleasant for the residents of the house.
