Problems solved by technology

However, since only one set of infrared emitting probes and infrared receiving probes are used, there is also the problem that the control command is too single, and the complete operation of the range hood cannot be realized.
In addition, the infrared receiving probe is exposed from the inside of the fuselage through the transparent plate, which is easily interfered by the ambient light irradiated from the transparent plate, and anti-interference measures need to be added

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...

Abstract

The invention relates to a non-contact control method of an extractor hood. The extractor hood is provided with a plurality of infrared emitting diodes which emit infrared light outward and a plurality of infrared receiving sensors which detect infrared light reflected from outside, wherein the infrared emitting diodes and the infrared receiving sensors are in one-to-one correspondence. The method comprises the following steps: S1, sequentially emitting infrared lights outward by using the infrared emitting diodes and sequentially detecting the infrared light intensity of the corresponding infrared emitting diodes which emit infrared light and background infrared light intensity of the corresponding infrared emitting diodes which extinguish the infrared lights; S2, identifying control gestures in real time according to the infrared light intensity detected by the infrared emitting diodes; and S3, generating control commands to control the extractor hood according to the control gestures. The method provided by the invention prevents the operators from being directly contacted with the extractor hood to realize the control purpose so as to realize non-contact control, is simple and convenient to operate, sanitary to operate and good in reliability and can realize complete operation on the extractor hood.

Description

technical field [0001] The invention relates to the field of range hoods, and more particularly, to a non-contact control method for range hoods. Background technique [0002] At present, most of the control of household range hoods are operated by touch buttons, such as keyboard switches, light touch switches, capacitive touch switches and the like. When the keys are stained with oil, it will make people feel uncomfortable to operate them by hand. When the hands are not clean, it is inconvenient to operate the range hood due to hygienic considerations. The process of (1) wash your hands (2) operate the range hood (3) wash your hands (4) continue to make dumplings. [0003] Using a non-contact control method to control the range hood can better solve the above problems, but the existing non-contact control schemes have their own shortcomings and poor realizability. [0004] In an existing range hood, a pyroelectric human body infrared sensor is used to detect whether ther...
