An anti-pinch control device, an air conditioner and an anti-pinch control method thereof

Abstract

The invention discloses an anti-pinch control device, an air conditioner, and an anti-pinch control method thereof. The device comprises a microwave sensor (3), an photoelectric switch (4) and a controller (5), wherein the microwave sensor (3) is used for acquiring a first detection signal for detecting whether a human body is close to an air outlet panel (2) of the air conditioner (1) to be controlled or not within a self-detection range; the photoelectric switch (4) is used for acquiring a second detection signal for detecting whether a hand pinching phenomenon occurs or not at the air outlet panel (2) of the air conditioner; and the controller (5) is used for controlling the air conditioner (1) to run according to the first detection signal and the second detection signal, so that anti-pinch control is realized. According to the scheme provided by the invention, the defects that in the prior art, a user feels pain when being pinched, frequent shutdown is easy to occur, and the userexperience is poor can be overcome, and the beneficial effects that the pinch pain is reduced, frequent shutdown is not easy to occur, and the user experience is good are realized.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a hand-pinch prevention control device, an air conditioner and a hand-pinch prevention control method thereof. Background technique [0002] At present, the hand clamping method adopted by the cabinet machine is only judged by the photoelectric switch (for example: when the high level or low level of the photoelectric switch is detected for 2 consecutive seconds, it is considered that the hand is locked), and there is obvious difference when experiencing the hand clamping. Pain, and when the sweeping blades are sweeping due to human-intentional blocking (for example: children will deliberately block the drum of the air conditioner and cause the child's hand to report a fault), the motor will also report a fault and stop the operation of the whole machine. This gives the user the feeling of frequent downtime, and the experience is not good. [0003] In the pr...
