Device and method for controlling sliding door of air conditioner

Abstract

The invention discloses a device and a method for controlling a sliding door of an air conditioner. The device is characterized in that: a transmitting end and a receiving end of an optoelectronic switch are arranged on the two sides of a connecting rod of the sliding door; the upper end and the lower end of the connecting rod of the sliding door are provided with two light leakage holes; the positions of the light leakage holes correspond to the position of the optoelectronic switch; when the connecting rod of the sliding door moves upwards and the top end of the connecting rod props againstan upper sliding baffle block, emitted light of the optoelectronic switch is illuminated on the receiving end of the optoelectronic switch through a lower light leakage hole; and when the connecting rod of the sliding door moves downwards and the bottom end of the connecting rod props against a lower sliding baffle block, the emitted light of the optoelectronic switch is illuminated on the receiving end of the optoelectronic switch through an upper light leakage hole. The device is simple in structure and reasonable in design and saves the cost, and the method is simple in operation, can accurately determine the position state of the sliding door and ensure the normal opening and closing of the sliding door.

Description

technical field [0001] The invention relates to the technical field of air conditioner sliding doors. Background technique [0002] Exhaust outlets of existing air conditioners, especially cabinet-type air conditioners, are mostly equipped with sliding doors that can slide up and down. The door is closed to prevent outside dust from entering the exhaust port. The traditional air conditioner uses two photoelectric switches to control the sliding door of the air conditioner. The photoelectric switches are placed in the left and right or upper and lower positions respectively. When it reaches the corresponding position, it makes a position judgment to achieve the purpose of control. [0003] Simultaneously, in order to prevent the sliding door from exceeding the stroke range, all air conditioners with sliding door structure add sliding blocks to the operating structure, so that the extreme position that the sliding door can operate is also just within the detection range of t...
