Abstract

The invention provides an air conditioner external unit humidity detection and protection method and device, and an air conditioner. A humidity sensor is arranged inside a crate of an air conditionerexternal unit, detects the working environment humidity of each functional component of the air conditioner external unit in real time, and gives early warning according to the surface humidity of a radiator of the air conditioner external unit, and when the surface humidity of the radiator of the air conditioner external unit exceeds the safety threshold value, the air conditioner external unit is controlled to stop working, and the dehumidifying function can be started at the same time. By monitoring of the humidity sensor additionally arranged on the radiator of the air conditioner externalunit, the inner working humidity of the air conditioner can be effectively monitored, and the risk possibly generated by direct contact of the sensor and a power device is avoided at the same time; and effective protection and reminding are achieved for extreme bad conditions, and when the humidity exceeds the safety threshold value, a moisture-proof agent is exposed for dehumidifying, and a circuit board is prevented from being damaged and affecting the service life of a product.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a humidity detection and protection method and device for an air conditioner external unit and an air conditioner. Background technique [0002] With the continuous progress of the economy, the application of air conditioners has become more and more extensive, and air conditioners have become one of the most common household appliances. At present, household inverter air conditioners encounter extreme weather in coastal areas, which will easily lead to excessive moisture in the control box of the outdoor unit. High-power devices run under high current conditions for a long time, which will easily damage the circuit board, affect the life of the product, and affect the air conditioner. device reliability. Contents of the invention [0003] In view of this, the present invention aims to provide a humidity detection and protection method, device and air conditioner for ...
