Range hoods are already necessary for home decoration, but many of them don't know the correct installation and use requirements, which causes unnecessary trouble for themselves. For example, do you think that the kitchen door and window should be closed when using the range hood?
Many people do not like to open the door when using the range hood, worry about the smell of the smoke to the living room or the room, and do not like to open the window, these methods are not conducive to efficient smoke. The range hood must have the same amount of air to be added to form the air flow effect while the kitchen fumes are discharged. The less the amount of air added, the slower the air flow and the less smoke is discharged. The correct way to do this is to properly open the doors and windows of the kitchen when using the range hood so that the air outside the kitchen is unobstructed.
In order not to meet the head, some people put the range hood too high. When cooking produces a lot of oil smoke, the smoke spreads during the ascent process, and it has spread to other spaces in the kitchen before reaching the range hood. On the contrary, some people install the range hood to be more conducive to the discharge of soot, and for users who use the gas stove, the installation height of the range hood is lower than the regulation, which may cause safety hazards such as fire of the range hood.
According to the safety standards of China's range hoods, the range of the range hood installed above the gas stove should be at least 650mm away from the support surface of the cooking utensils. In order to ensure the effect of the range hood, the installation height of the side suction range hood can be appropriately reduced in accordance with the above safety standards.
Because the longer the pipe, the more the number of turns, the greater the resistance to smoke exhaustion. Therefore, when selecting the position of the cooktop, it should be as close as possible to the public flue or the exhaust hole on the wall to reduce the length of the pipe and the number of turns.
After using the range hood for a period of time, there will be a lot of oil in the air inlet. These oily sticky dust will form stubborn dirt, which will reduce the effective area of ​​the air intake grille and affect the air intake. At the same time, a large amount of oil will also affect the safety of use. Causes fire and other dangers. Therefore, the outer surface of the range hood and the outer surface of the air inlet should be wiped regularly. Do not clean the inside of the range hood as much as possible. The oil net is difficult to disassemble. It is easy to cause damage to the machine during the disassembly process. It is even necessary to have professional electrical operation ability and familiar with the structure of the range hood.
Therefore, you should contact the after-sales service for professional cleaning of the range hood, do not easily believe that the "guerrillas" of the range hood are cleaned. Source: Anhui Daily Hu Mingbing
