To install the hood in the kitchen in a private house on your own, you do not need to have special knowledge or skills, but you should be careful and carefully follow the instructions. The device protects the room from unpleasant odors, removes polluted air, cleans it from dust particles and food, and eliminates harmful substances that are formed during the combustion of gas.
Requirements for the hood in the kitchen in a private house
When choosing a hood for the kitchen, you need to pay attention to the air pressure indicator that the blower creates. The higher it is, the greater the performance of the product. A good hood has several fans that blow air at different speeds.
The performance of the hood is determined by the amount of air that the device can remove from the room. Some devices are capable of outputting 180–700 m³ / h. It should be borne in mind that the higher the performance, the more the fan will make noise.
To determine what exhaust power is needed for the kitchen, you should determine the volume of the room and multiply it by 10. According to sanitary standards, a complete replacement of the air in the room should be done 10–12 times per hour, so the volume of the room is multiplied by 12 (air exchange rate). The result is multiplied by 1.3 (reserve factor). It is necessary to consider how the calculation is made using the example of a kitchen with an area of 6 m² and a height of 2.5 m: ((6 * 2.5) * 12) * 1.3 = 234 m³ / h. For effective ventilation of the room, an extractor hood with a capacity of 230–240 m³ / h is needed.
The dimensions of the device must correspond to the dimensions of the gas stove or exceed them by 10–20 cm. Failure to comply with these conditions will cause fumes and combustion products to rise past the hood and the hanging furniture will begin to deteriorate. Machined aluminum has proved to be the best material.
You can also make a hood in a private house with your own hands. Without fans, the device must be connected to a vertical natural ventilation duct. However, this method does not remove all odors in the room.
Need ventilation in a wooden house
In a wooden house, which is being built using the latest technologies, a ventilation system must be installed. This is due to the high tightness of the building. The removal of dirty air through windows and vents is not a sufficient condition.
The natural ventilation system is attractive because of its low cost, but it is not able to quickly remove odors from the kitchen or humid air from the bathroom. For effective air exchange in the kitchen in a wooden house, you need to install a special device of appropriate power.
The supply and exhaust ventilation system is only enough to ensure the flow of fresh air into the house and eliminate excess carbon dioxide and unpleasant odors. For high-quality air purification in the kitchen, this, like a natural system, is not enough.
You can use a high-quality natural-type kitchen ventilation system, provided that it was originally laid down during the design of the house and carried out by specialists.
What hood to install in the kitchen of a private house
Before you learn how to install the hood, you need to determine what types of devices are and what filter system they are equipped with. In order for the cassettes not only to eliminate an unpleasant odor, but also to collect oily particles, a synthetic winterizer or interlining should be provided in their design. Filters of this type are disposable. Reusable cassettes are made of aluminum or steel, and special grease solvents are used to clean them.
There are also carbon filters that not only trap soot and fats, but also neutralize unpleasant odors. The disadvantage of such products is that they are disposable. According to the design features of the hood, there are the following types:
Hoods of this type attract buyers with their small size and simplicity of design. Since they do not have a chimney, they can be attached to the bottom of a wall cabinet. If the size of the device is not enough to close the stove, you should pay attention to retractable models. Such products are suitable for rooms with a small area.
Flat hoods work on the principle of air recirculation. They absorb it with fans, clean it, and then return it to the room. As a rule, such products are equipped with carbon filters.
This type of hood also belongs to the recirculation type. Since the device can be installed inside a wall cabinet, it is unremarkable and harmoniously fits into the interior. The body is cube-shaped with a retractable panel for more air trapping. First, the hood is installed in the wall, and then the cabinet is hung.
A device of this type is distinguished by a large volumetric shape resembling a hemisphere or trapezoid. The design allows you to install powerful fans and several filters. Therefore, experts believe that hoods of this type are the most effective. Cleaning can be recirculated or through connection to a ventilation shaft. Such products are installed in rooms where there is no access to fresh air.
Installing a hood in the kitchen
Not everyone knows how to properly make an air purification system in the kitchen. To do this, you need the necessary set of tools:
- drill or screwdriver;
- a hammer;
- self-tapping screws;
- tape measure and ruler;
- corrugated pipe;
- pencil and level.
Since the most common is the installation of a hood in the kitchen in a cabinet above the hob, this option will be considered.
Preparing for installation
To install the hood in the kitchen with your own hands, you should prepare the surface and perform preliminary calculations. First you need to determine the distance from the hood to the ventilation duct and cut off the corrugated pipe. It is important to take into account the fact that the pipe is stretched, so you can make it a little shorter in length.
Since the cabinet must have an air duct with a cross section of 130 mm or more, a corresponding hole is cut out in the upper wall. It can be round or rectangular, depending on the cross section of the duct.
The case is fixed with self-tapping screws to the bottom panel of the cabinet. Sometimes it is hidden inside, having previously cut a groove of the appropriate size.
Exhaust fan connection
Since the power consumption of household hoods does not exceed 1 kW, they can be connected to simple sockets. Also, the connection of the hood in the kitchen can be made to the existing wiring. The cross section of the wire must be 2.5 mm, the conductor is stranded copper with a non-combustible braid.
Connecting the hood in the kitchen to the ventilation
The pipe is best brought to the ventilation along the top of the cabinets. It is advisable not to bend it at a right angle, as this prevents the free movement of air. Sometimes a back draft can be created in the ventilation shaft. A non-return valve is installed when connecting the hood and protects the room from the penetration of unpleasant odors from the outside. In a private house, the air duct can go through the wall to the street or into a special hole. A vent can also serve as a ventilation opening.
The air duct is inserted into the ventilation shaft and secured with a special overlay. It is desirable to fix the junction of the pipe with the exhaust channel with a clamp, but you can not do this if the power of the device is small.
When you need exhaust ventilation in a dome-type kitchen, you should consider that it is fixed to the wall. Therefore, holes are first made, dowels are inserted and the product is fastened with bolts or anchors. The connection to electricity and the ventilation shaft follows the same principle as described earlier.
Nuances to consider when installing a hood in a private house
When the hood is installed in the wall, it is necessary to make the holes correctly and fix the device. The level of vibration should be taken into account if the fans are powerful. Otherwise, over time, the fasteners may loosen and fall out. The pipe should be given smooth bends so that the air moves freely to the ventilation shaft.
If the owner has basic building skills, he can easily install any type of hood in an apartment or house with his own hands.
