Problems solved by technology

[0006] Although the above-mentioned solution designs the smoke deflector into multiple pieces, to a certain extent, the problem of the single air inlet is solved, but the air inlet area and the air inlet form have not been greatly improved, and the fan will still be oppressed, resulting in The performance of the fan cannot be fully released, and the fan noise is loud

Abstract

The invention discloses a range hood, which comprises a casing, an air inlet is formed in the casing, the front side of the casing is open, and a smoke guiding plate is arranged at the opening of the front side of the casing The assembly is characterized in that: the smoke guide plate assembly includes two first smoke guide plates and two second smoke guide plates arranged side by side, the first smoke guide plate is located in the middle and covers the air inlet, one of The second smoke guide plate is located on the left side of the first smoke guide plate on the left side, and another second smoke guide plate is located on the right side of the first smoke guide plate on the right side, and the first smoke guide plate is rotated through the longitudinal extension. The shaft is rotatably connected to the housing so that the first smoke guide plate can rotate relative to the housing, and the rotation axes of the two first smoke guide plates are close to each other, the second smoke guide plate can move longitudinally relative to the housing, and each of the first smoke guide plates The first smoke guide plate is linked with the second smoke guide plate. Compared with the prior art, the present invention has the advantages that four air inlets can be realized, the area of ​​the air inlets can be effectively increased, and the oil fume absorption effect can be improved.

Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a range hood. Background technique [0002] The range hood uses the principle of fluid dynamics to work, sucks and exhausts the range hood through a centrifugal fan installed inside the range hood, and uses a filter to filter some grease particles. The centrifugal fan includes a volute, an impeller installed in the volute and a motor that drives the impeller to rotate. When the impeller rotates, a negative pressure suction is generated in the center of the fan, and the oil fume under the range hood is sucked into the fan, and after being accelerated by the fan, it is collected by the volute and guided out of the room. [0003] At present, common range hoods on the market include top suction and side suction. The power source of the side-suction range hood is closer to the stove, and most of the oil fumes that are closer to the stove are sucked away in an arc. The advantage is ...
