Problems solved by technology
[0005] The object of the present invention is to provide an air conditioner zero live wire conditioning device and its control method, and an air conditioner to solve the problem of using zero line, live line and communication line for communication between the indoor unit and the outdoor unit of the air conditioner. If the live wire is reversed, it will cause the communication between the indoor unit and the outdoor unit of the air conditioner to be unable to communicate normally, which will affect the normal start-up and use of the air conditioner. By detecting and correcting the zero live wire of the outdoor unit of the air conditioner, it is possible to prevent the outdoor unit of the air conditioner from The problem of communication failure caused by the reverse connection of the neutral and live wires of the air conditioner, and the effect of improving the communication reliability of the outdoor unit and indoor unit of the air conditioner

Embodiment Construction
[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0033] The indoor unit and outdoor unit of the air conditioner use neutral wire, live wire and communication wire for communication. Once the neutral wire and live wire on the outdoor unit side of the air conditioner are reversed, the communication between the indoor unit and the outdoor unit of the air conditioner will fail. This kind of communication failure nee...

The invention discloses a null line and live line conditioning device of an air conditioner, a control method of the null line and live line conditioning device and the air conditioner. The null line and live line conditioning device comprises a null line and live line detection unit for detecting whether a to-be-detected end of an alternating current power supply input end of an outdoor unit is a null line input end or a live line input end to obtain a detection result; the control unit is used for generating a control instruction according to the detection result; and the phase-change switch unit acts according to the control instruction, so that the live wire input end in the first input end and the second input end is connected to the live wire connecting end of the null-live wire communication unit, and the null wire input end in the first input end and the second input end is connected to the null wire connecting end of the null-live wire communication unit. According to the scheme, the null line and the live line of the air conditioner outdoor unit are detected and corrected, the problem of communication faults caused by reverse connection of the null line and the live line of the air conditioner outdoor unit can be solved, and the communication reliability of the outdoor unit and the indoor unit of the air conditioner is improved.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a zero live wire conditioning device for an air conditioner and a control method thereof, an air conditioner, in particular to a zero live wire self-regulating circuit for an air conditioner and a control method thereof, and a zero live wire self-regulating circuit for an air conditioner air conditioner. Background technique [0002] Most air conditioners consist of an indoor unit and an outdoor unit. The indoor unit and the outdoor unit need to communicate with each other to realize complex functions. For example, an inverter air conditioner needs to change the operating frequency of the compressor of the outdoor unit according to different working conditions, which requires frequent communication between the indoor unit and the outdoor unit. The distance between the indoor and outdoor units is far and there are many interferences. In order to ensure the ...
