Abstract

The invention discloses an anti-leakage control device, an air conditioner and an anti-leakage control method thereof. The device comprises: a control switch, arranged between a filter circuit and a grounding terminal, for switching on or off the filter circuit under the control of a control unit; The path between the circuit and the ground terminal is used to disconnect the path between the filter circuit and the ground terminal to prevent the filter circuit from leaking to the ground terminal; the control unit is used to determine the operating parameters of the air conditioner when the air conditioner is powered on, and The on or off of the control switch is controlled according to the operating parameters of the air conditioner; the operating parameters of the air conditioner include: working state and / or operating mode. The solution of the present invention can solve the problem of high safety risk in use in the way of improving the anti-electromagnetic interference ability of the inverter air conditioner by connecting Y capacitors in series between the neutral line and the ground, and achieve the effect of reducing the safety risk in use.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an anti-leakage control device, an air conditioner and an anti-leakage control method thereof, in particular to a filter control circuit for realizing anti-leakage control, an air conditioner with the filter control circuit, and the air conditioner anti-leakage control method. Background technique [0002] In order to improve the anti-electromagnetic interference ability of inverter air conditioners, Y capacitors are generally connected in series between the neutral line and the ground. However, when the capacity of the Y capacitor is large, the Y capacitor will generate a large leakage current, which will lead to an increase in the leakage current of the air conditioner, and if the large leakage current exceeds a certain limit, the user will have the risk of electric shock; At the same time, if the Y capacitor fails and breaks down, it will cause the ground...
