Abstract

The invention provides a device and method for detecting inversion of a compressor. The device comprises a piston mechanism, an optoelectronic switch and a detection circuit. The piston mechanism can be arranged on an air inlet of the compressor in a sealed mode and comprises a sealing ring and a guide rod in the sealing ring. The optoelectronic switch is arranged at the top end of the piston mechanism and comprises an emitting end and a receiving end which are located on the two sides of the piston mechanism, when the air inlet does not exhaust air, the receiving end receives an optical signal emitted by the emitting end, and when the air inlet exhausts air, the guide rod is jacked up to be between the emitting end and the receiving end, transmission of the optical signal is blocked, and the receiving end cannot receive the optical signal emitted by the emitting end. The detection circuit is connected with the optoelectronic switch and used for judging whether the receiving end receives the optical signal or not, and if the receiving end does not receive the optical signal, the inversion of the compressor is judged, and an alarm circuit is controlled to give an alarm. Therefore, accuracy and reliability for detecting the inversion of the compressor are improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and more specifically, to a device and method for detecting reverse rotation of a compressor. Background technique [0002] At present, in the process of testing the program of the main board of the external unit of the household air conditioner, it often occurs that the compressor is reversed due to incorrect wiring of the main board of the external unit or incorrect program of the main board. Among them, the reverse performance of the compressor is mainly the discharge of gas from the air inlet. [0003] Since the reverse rotation of the compressor will affect the normal operation of the air conditioning unit, for example, the air conditioning unit will perform heating in the cooling mode, and the air conditioning unit will perform cooling in the heating mode. Therefore, in order to eliminate the reverse rotation problem of the compressor, in the prior art, it is mainly judged whether...
