The invention discloses an air conditioner and a fault detection method and device thereof, and relates to the technical field of air conditioners. The operation state of a driving unit is monitored in real time, and an air conditioner door plate is accurately positioned when the driving unit breaks down. The fault detection method comprises the steps that a motor is controlled to rotate in a setrotation range in a set rotation direction according to the current position information of the air conditioner door plate and the target position information of the air conditioner door plate; rack parameter information sent by the detection device and real-time rotation information sent by the motor are received; and in the set rotation range, under the condition that it is determined on the basis of the rack parameter information that the motor encounters one-time rotation blocking, the rotation blocking position information of the air conditioner door plate is determined when the motor encounters rotation blocking according to the current position information of the air conditioner door plate, the set rotation direction of the motor and the actual rotation information of the motor. Thefault detection device is used for executing the fault detection method. The fault detection method is applied to air conditioner control.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and its fault detection method and fault detection device. Background technique [0002] At present, in order to improve the indoor air quality during the operation of the air conditioner, an air purification module is installed in the indoor unit of the air conditioner. The air purification module is located at the lower part of the temperature adjustment module of the air conditioner indoor unit, and the air outlet of the air purification module is located below the air outlet of the temperature adjustment module. . The air purification module is provided with a filter screen for filtering the indoor air. The filter screen is located on both sides of the air outlet of the air conditioning module, and the direction of the filter screen socket is towards the front of the indoor unit. [0003] In order to facilitate the replacement of the air filter, t...
