The invention relates to the technical field of intelligent household appliances, and discloses a control circuit for an outdoor unit of an air conditioner. The control circuit comprises a first rectification power supply module, a second rectification power supply module and a first relay; a null line input end of the first rectification power supply module is connected with a null line of an outdoor power line, a live line input end is connected with a live line of the outdoor power line, and two output ends are connected in parallel with the two ends of a first energy storage module and are connected in parallel with a fan control module; a null line input end of the second rectification power supply module is connected with the null line of the outdoor power line, a live line input end is connected with the live line of the outdoor power line, and two output ends are connected in parallel with a chip control module; the static contact end of the first relay is connected with the null line of the outdoor unit power line, and the movable contact end is connected with the null line input end of the first rectification power supply module and the null line input end of the second rectification power supply module. According to the scheme, when an outdoor fan rotates reversely, it is guaranteed that the chip control circuit does not work, and over-current tripping of an air conditioner circuit breaker caused by high voltage generated by reverse rotation of the fan is avoided. The invention further discloses a control method for the outdoor unit of the air conditioner and the air conditioner.
Description
technical field [0001] The present application relates to the technical field of smart home appliances, for example, to a control circuit and control method for an outdoor unit of an air conditioner, and an air conditioner. Background technique [0002] At present, after the air conditioner is turned off and enters the standby mode, the outdoor fan will reverse the power generation under the action of the external wind, so that the chip control circuit of the outdoor unit will work with electricity, causing the power line of the outdoor unit to charge the switching power supply capacitor of the chip control circuit, and the instantaneous value of the charging current will be Larger, which in turn causes the air conditioner circuit breaker to trip. [0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in related technologies: [0004] In the related art, a diode is added in the control circui...
