Embodiment 1
[0068] The present invention provides a non-contact control method for a range hood. The control method is applied to a range hood, and the range hood can adopt such Figure 1-3 The structure shown is implemented. Such as Figure 1-3 As shown, the range hood includes a body 1 and a non-contact control device 2. The non-contact control device 2 is installed on the operation surface of the body 1, and is controlled by detecting in real time whether the user of the range hood makes an effective control gesture. The cooker hood performs the corresponding action. The non-contact control device 2 includes several infrared emitting diodes, several infrared receiving sensors, optical filters 23 and PCB substrate 24, the number of infrared emitting diodes and infrared receiving sensors is N, 2≤N≤10, and N is a positive integer. In this embodiment, the infrared emitting diodes include four, 221-224, and the infrared receiving sensors include four correspondingly, 211-214, and the infr...
