Double air inlet range hood and control method

Abstract

The invention provides a double-air-inlet range hood. The double-air-inlet range hood comprises a box body, an air deflector and a switch panel, wherein a smoke collection chamber is arranged on the inner side of the air deflector; an opening for communicating the smoke collection chamber with the outside is formed between the switch panel and the air deflector; a left air inlet and a right air inlet are formed in the base plate of the smoke collection chamber; a division board is arranged between the two air inlets; an air inlet seal plate is arranged on the back of the smoke collection chamber in a hinged mode; the air inlet seal plate is provided with a driving device for driving the air inlet seal plate to overturn; a group of smoke detection devices is arranged in each of the two areas, separated by the division board, of the smoke collection chamber, and the smoke collection chamber is further provided with a controller for controlling the driving device to adjust the overturning angle of the air inlet seal plate. The double-air-inlet range hood has the benefits that the left air inlet and the right air inlet are formed, inlet air of the left air inlet and inlet air of the right air inlet do not disturb with each other through the division board arranged in the middle, and the air inlet seal plate capable of overturning is arranged, so that the double-air-inlet range hood is simple in structure and reliable in action; the opening of the air inlets of the air inlet seal plate is automatically adjusted by detecting smoke concentration, so that the efficiency of the range hood is fully utilized, and the adaptability is good.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to a range hood with double air inlets. Background technique [0002] The main performance evaluation index of the current range hood is the air volume, that is, the ability to remove oil fume, and the other index is the working noise. Often this is a pair of contradictions. Range hoods with large air volume increase the air volume and suction by increasing the speed of the main motor to drive the volute impeller, but at the same time bring a lot of noise; while range hoods with relatively low noise on the market have air volume and Suction is often not great. On the other hand, during the cooking process in the family, one side of the stove is often working, which produces relatively large oil fume, while the other side produces little or no oil fume. However, the current range hoods, especially the near-suction / side-suction type, have a relatively large smoking area on the pane...

AI Technical Summary

Problems solved by technology

However, the current range hoods, especially the near-suction / side-suction type, have a relatively large smoking area on the panel. Although the air volume of the whole machine is very large, some can reach 17 cubic meters per minute, but the smoking port closest to the oil fume The suction force is not the maximum, which causes the range hood to inhale more clean and invalid air

[0003] Existing range hoods also have double air inlet range hoods, which can independently adjust the opening according to the use of the two lower burners, but the left and right air inlets cannot be isolated from each other, and there is mutual interference, and the opening of each air inlet independent adjustment, unable to coordinate
