Scientists calculated that during the year in the process of cooking for a family of 3-4 people, about 9 kg of fatty substances, fumes and smokes are formed. In the absence of an extract, most of these substances will fall into the lungs. In addition, different pathogens are formed, which can cause diseases.
How to make an hood with your own hands – this question arose in many housewives. When using the hood, the air flows through the fan, previously filtered and cleaned through a mechanical filter (usually a metal mesh and special material), and sometimes activated charcoal is used. After filtration, the air enters the room or outside the house.
But it is better that the ventilation of contaminated air removes from the kitchen through a special air vent. In this way, we simply, quickly and effectively retire bad air. But in this case, there is a small problem: the volume of air that was taken outside the room must be replaced with clean and it must, to take it from somewhere. With installed plastic windows, there is an option to use the function of constant ventilation. So fresh air will enter the room.
Parameters such as the power and performance of the hood when choosing depends on the volume of the room. Air exchange must be designed in such a way that in one hour air is replaced about 10 times, at least 5 times. For example, in a kitchen with a volume of 40 m3, it is necessary to use an extract with a capacity of about 200-400 m3/hour
Selecting and installing hoods
The hood in size should not be less than the kitchen slab, otherwise part of the air saturated with various smells and fats will settle on surrounding objects.
DIY hood is installed – a completely simple process. In height, the hood is attached so that it is convenient to use the stove (just above the head). But lower than 50-65 cm should not install it in any case-this will not meet the requirements of fire safety. In addition, the hood in this case will be very hot. There were cases of ignition of fat, which accumulated on the extract of the hood. Therefore, it is necessary to periodically clean it and fully maintain it.
The length of the exhaust box should not be too long, t. to. As a result, a large resistance of the air flow is obtained, while part of the contaminated air does not completely disappear and settles. If you can not do without a long air vent, it is necessary to install an intermediate fan that will enhance the thrust. The hood is fully electric, therefore, during installation, it is necessary to pay attention to the correctness of the connection and insulation of the wiring.
The mass of kitchen hoods are not large, so it is enough to fix it to the wall with dowel-samores and hang it on the openings provided. The air car is laid as smooth, without sharp turns. The end is taken to the street or a common ventilation riser.
