Abstract

The invention discloses an air conditioner outdoor unit power source control circuit, an air conditioner and a control method. The air conditioner comprises an outdoor unit and a plurality of indoor units. The power source control circuit comprises a first branch circuit, a second branch circuit, a first on-off control circuit, a second on-off control circuit and a control unit, wherein the firstbranch circuit is used for enabling a firing line signal of the indoor unit to supply power to a switch power source to awaken the outdoor unit when any one of the multiple indoor units is started, one end of the second branch circuit is connected with a firing line, the other end of the second branch circuit is connected with the switch power source, the first on-off control circuit is used for controlling on and off of the first branch circuit, the second on-off control circuit is used for controlling on and off of the second branch circuit, and the control unit is used for controlling the second branch circuit to be on through the second on-off control circuit and the first branch circuit to be off through the first on-off control circuit so as to enable the outdoor unit to be powered on and work after the outdoor unit is awakened. The air conditioner outdoor unit power source control circuit can reduce the energy consumption of the outdoor unit and meet the requirement for the lowenergy consumption.

Description

technical field [0001] The invention relates to the technical field of electric appliance manufacturing, in particular to a power supply control circuit of an outdoor unit of an air conditioner, an air conditioner and a control method. Background technique [0002] Multi-connected air-conditioning system, that is: one-to-many air conditioners, that is, one outdoor unit, which is connected to two or more outdoor units at the same time. In related technologies, in order to ensure that the air conditioner can work normally after any indoor unit is turned on, it is necessary that when all indoor units are turned off, the outdoor unit is in a power-on working state, such as a standby state. At this time, after any indoor unit is turned on, the outdoor machine can work normally. [0003] There are the following disadvantages: because the outdoor unit is in a standby state when all the indoor units are turned off, the outdoor unit has relatively large standby power consumption, th...
