Problems solved by technology
In this way, the control gestures are recognized in real time according to the infrared light intensity detected by each infrared receiving sensor, and then the range hood is controlled according to the predetermined gestures. The problem of inaccurate control caused by counting and acquisition errors; but when the concentration of oil fume is high, or the height of the user is high, the oil fume and the user's body will interfere with the reception of infrared light (the oil fume and the human body will refract or scatter infrared light ), its anti-drying performance is still poor, so the non-contact control method still needs to be improved

The invention relates to a non-contact control device of a range hood and a control method of the non-contact control device. The non-contact control device comprises a main control module for controlling a function execution module of the range hood, and a non-contact instruction detection module connected with the main control module. The non-contact control device is characterized in that the non-contact instruction detection module comprises a proximity induction module, an image camera and an image recognition module; in addition, the non-contact control device further comprises a non-contact instruction processing device connected with the image recognition module; a plurality of control instructions paired with different head profile actions one to one are stored in the non-contactinstruction processing device in advance; and the non-contact instruction processing device identifies eye irises of a correct user according to the image recognition module, then finds out the control instruction paired with the head profile action according to the head profile action of the user, sends the control instruction to the main control module and controls the function execution module.Compared with the prior art, the non-contact control device has the advantages that the range hood is controlled by the eye irises and the head actions, the non-contact control device is more convenient and quicker than a gesture control device, and the user can let the both hands free.
Description
technical field [0001] The invention relates to a non-contact control device of a range hood and a control method thereof. Background technique [0002] The range hood has changed the general environment of the kitchen. It can quickly take away the oily fume harmful to the kitchen environment and human body, discharge the oily fume to the outside, reduce pollution, purify the air, and have the safety guarantee function of anti-virus and explosion-proof. Range hoods have become essential kitchen equipment for modern families. After a range hood is used for a long time, the touch panel or the push switch will be stained with oil. At this time, the fingers will be dirty when operating it. In addition, when there are kitchen utensils in the hand or the hands are dirty, the touch panel will be polluted. panel or push switch. [0003] The Chinese patent No. ZL 201520881739.8 (Notice No. CN205156087U) discloses a range hood gesture control system, which includes a display module,...
