Problems solved by technology
[0002] The indoor unit and outdoor unit of the inverter air conditioner usually use the current loop for real-time communication, and the communication power module of the current loop usually uses a half-wave rectification filter type stabilized power supply. After the outdoor unit of the air conditioner is powered on, the communication power module of the current loop is always Open to supply power to the current loop, resulting in low voltage of the power grid, and communication failure between indoor and outdoor units due to insufficient voltage of the communication power supply module

The present invention provides a communication control method and device for an air conditioner, and the air conditioner. The communication control method includes: obtaining the communication status of the communication modules of the indoor unit and the outdoor unit; The communication power supply module for the power supply of the communication module. The communication control method and device of the air conditioner and the air conditioner of the present invention open or close the communication power supply module that supplies power to the communication modules of the indoor unit and the outdoor unit according to the communication status. When the communication power supply module is turned on, it supplies power to the communication module. The communication power supply module When it is turned off, the communication power supply module is charged and the voltage rises, thereby avoiding communication failure between the indoor unit and the outdoor unit due to insufficient voltage of the communication power supply module.
Description
technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a communication control method and device for an air conditioner and the air conditioner. Background technique [0002] The indoor unit and outdoor unit of the inverter air conditioner usually use the current loop for real-time communication, and the communication power module of the current loop usually uses a half-wave rectification filter type stabilized power supply. After the outdoor unit of the air conditioner is powered on, the communication power module of the current loop is always Open to supply power to the current loop, resulting in low voltage of the power grid, and communication failure between the indoor unit and outdoor unit due to insufficient voltage of the communication power supply module. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For th...
