Range hood with adjustable airdraft plate

Abstract

The invention discloses a range hood with an adjustable airdraft plate. In the range board, an air blower is arranged in a rack; the airdraft plate is arranged at the lower part of the rack; a lower panel of the airdraft plate is provided with an airdraft hole; an panel of the airdraft plate is provided with an air hole; one end of arc tower type telescopic air dust assembly is communicated with an inner chamber of the airdraft plate through the air hole, while the other end is connected with the rack and communicated with a pressure-equalizing chamber in the rack; the pressure-equalizing chamber is communicated with the air blower; the airdraft plate is connected with the rack through an elastic-friction rotational-positioning hinge; and the airdraft plate can rotate around the hinge to adjust the position and self lock. The range hood is characterized in that the range hood can adjust the position of the airdraft plate, is favorable for absorbing oily fume, and has good oily fume absorbing effect and low requirement on the airdraft power, and saves energy consumption. In addition, the range hood is applicable for a device to reject cooking smoke gas.

Description

technical field [0001] The invention relates to a device for removing cooking smoke, in particular to a range hood with an adjustable air suction plate. Background technique [0002] With the continuous development of science and technology, people's living standards continue to improve, and the quality of the kitchen environment has attracted widespread attention. The pollution problem is serious. After people inhale cooking fumes, a series of "drunken oil syndrome" symptoms will occur, which will cause damage to the human body. [0003] The problem that the existing range hood cannot completely eliminate the oil fume is manifested in the following aspects: [0004] 1. Ordinary range hoods are affected by the operating space, and the distance from the oil fume to the air inlet is relatively large (generally 700mm for ordinary range hoods). Under the influence of comprehensive airflow factors such as indoor air convection, the oil fume will spread everywhere. [0005] 2. Th...

AI Technical Summary

Problems solved by technology

[0004] 1. Ordinary range hoods are affected by the operating space, and the distance from the oil fume to the air inlet is relatively large (ordinary range hoods are generally 700mm). Under the influence of indoor air convection and other comprehensive airflow factors, the oil fume will spread everywhere.

[0005] 2. The existing fan technology is limited by the noise of the fan, and the exhaust air volume cannot be increased. At the same time, increasing the power will cause energy loss, which cannot solve this problem well

[0006] 3. There is an open space between the oil fume source and the fan outlet. If they are arranged in the fume hood, although the oil fume can be completely eliminated, it takes up too much space, and it is inconvenient to operate, affecting the appearance and high cost. It is very expensive in the civil field. use less

[0007] 4. In order to minimize the distance between the source of oil fume and the outlet of the fan, although the side suction structure reduces the distance between the source of oil fume and the outlet of the fan, the effect of extracting oil fume has been significantly improved, but it is limited by different cookers. Can not pass through the appropriate distance between the source of oil fume and the air outlet of the fan, and when the amount of oil fume generated is large, the oil fume cannot be completely eliminated

[0008] 5. The method of wrapping the cooking utensils and the stove, and placing the fan under the fan can completely eliminate the oil fume, but the choice of cooking utensils is limited, and at the same time affects the thermal efficiency of the stove and the comprehensive performance of CO flue gas.

[0009] The range hood is an integral part of the kitchen equipment. The performance of the range hood needs to be improved without affecting the overall layout of the kitchen.
