Air conditioner, outdoor unit and power supply communication control system thereof

Abstract

The invention belongs to the field of air conditioners and particularly relates to an air conditioner, an outdoor unit and a power supply communication system thereof. During normal work, detected communication signal current is converted into corresponding high level or low level to be output to an integral module through a communication detection module in the power supply communication system of the outdoor unit, voltage is output to control on-off of a switching module after processing is conducted by the integral module, a switching power module works normally after the switching module is turned on, and a current loop communication circuit of the whole air conditioner works normally; after the switching module is in the standby state, the communication detection module outputs low level continuously due to the fact that no communication signal current exists, the voltage output by the integral module is lower than the breakover voltage of the switching module, the switching module works in the cut-off state, the switching power module is controlled not to work, and the whole air conditioner is in the low-power-consumption standby state. According to the air conditioner, the outdoor unit and the power supply communication system thereof, the technical problems that according to an existing air conditioner to which power is supplied by an outdoor unit, power consumption is high when the air conditioner is in the standby state and the requirement for low energy consumption cannot be met are solved.

Description

technical field [0001] The invention belongs to the field of air conditioners, and in particular relates to an air conditioner, an outdoor unit and a power supply communication control system thereof. Background technique [0002] At present, as countries around the world pay more and more attention to environmental protection issues and continuously introduce higher standards for standby energy consumption, all home appliance manufacturers are working hard to reduce the standby energy consumption of home appliances. [0003] For inverter air conditioners on the market, most of the time is in the standby state, and the standby power consumption is also high. An air conditioner generally includes an indoor unit and an outdoor unit, and the indoor unit usually supplies power to the outdoor unit. If the air conditioner is designed for low-power standby, the indoor unit usually cuts off the power supply of the outdoor unit so that the outdoor unit Completely power down, thereby...
