Problems solved by technology

[0009] This structure of the known air conditioner operating device, the lower end of its operating button 26 is made into a boss 26a, and the structure of the boss 26a is set in the hole 22b on the display cover 22, so that the operating button 26 can only be positioned at a certain position in the hole 22b. Therefore, there is a deformation of the display cover 22 or a size error of the operation button 26, and the resulting displacement of the operation button 26 in the left, right or circumferential direction affects the quality of operation, and even produces insufficient pressure with the contact switch 24b. Disable the operation of the operation button 26

Abstract

The operation device of air conditioner is formed from display cover, printed circuit board and operation button. On the display cover a guide sleeve and a spacing projection are set, on the printed circuit board several contact switches are set, and on the operation button the key groove, projection and press portion are set, and a ring groove is set on the periphery of the press portion, and the spring is mounted between said ring groove and contact switch. By adopting the above structure and measures, the operation button can be leftware-rightward moved. After operation the operation button can be automatically restored into its original state by means of spring action, so that the operation accuracy of the operation button can be raised.

Description

technical field [0001] The invention belongs to the field of air conditioning, in particular to an air conditioner operating device. Background technique [0002] Generally have following device in known technology air conditioner: with the compressor of high-temperature high-pressure compressor coolant; The refrigerant that above-mentioned compressor provides is carried out heat exchange, changes into the condenser of low-temperature refrigerant; The refrigerant that condenser provides is added The regulating valve that expands into a low-temperature and low-pressure refrigerant; the evaporator that vaporizes the refrigerant flowing through the above-mentioned regulating valve and absorbs heat; uses the refrigeration cycle composed of the above devices to keep the indoor air cool and comfortable. [0003] The air conditioner is composed of two parts: an indoor unit and an outdoor unit. The indoor unit includes a compressor, an outdoor heat exchanger, and a...
