Abstract

The invention discloses a discharge circuit of an air conditioner and a discharge method thereof. The discharge circuit of the air conditioner comprises a switching module, a voltage dividing module and a discharge module, wherein the switching module is connected with two ends of a power supply of the air conditioner, and the total resistance of the switching module is larger than or equal to 100M[omega]; the voltage dividing module is connected with the two ends of the power supply and the is connected with the switching module; and the discharge module is connected with the two ends of the power supply and is connected with the switching module, and when the switching module is cut-off, the discharge module starts discharging. According to the invention, the technical problem that a special discharge chip has large power consumption in the prior art is solved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner discharge circuit and a discharge method thereof. Background technique [0002] After the air conditioner is powered off, the voltage must drop below 34V within 1 second, so as to avoid the danger of electric shock caused by the power off of the air conditioner. Requirements in the national standard: Appliances intended to be connected to the mains through a plug shall be so constructed that, in normal use, when the prongs of the plug are touched, there will be no risk of electric shock due to charged capacitors . [0003] The electrical equipment is powered by the rated voltage, and then any one of its switches is placed in the "off" position. The electrical equipment is disconnected from the power supply when the voltage peaks, and in 1s after disconnection, use a switch that will not have a significant impact on the measurement. The instrument measures the ...
