Problems solved by technology

[0003] At present, the air conditioners on the market generally use AC water pumps, but the motor torque of AC water pumps is small, it is difficult to start, the speed of the water pump fluctuates when the water pump is expected to be heavy load, and even the performance of the motor is abnormal.
In addition, the noise of the AC motor is large, the vibration of the motor is obvious, and the operation fluctuates

Embodiment 1

[0086] see image 3 , the fault category includes the first fault category, according to the fault category of the work index parameter, the water pump 200 is controlled to work, including:

[0087] According to the first fault category, the driving torque of the water pump 200 is adjusted to a preset torque.

[0088]It can be understood that the first fault category of the water pump 200 is a fault category that can restore the normal operation of the water pump 200 by adjusting the driving torque of the water pump 200 . The range of the first fault category includes the low speed of the water pump 200, the high speed of the water pump 200, or the stop of the water pump 200. By detecting the working index parameters such as the speed of the water pump 200 or the current of the water pump 200, it can be judged whether the fault of the water pump 200 belongs to the first fault category. A failure category.

[0089] Exemplarily, the water pump 200 includes a water pump control...

Embodiment 2

[0096] see Figure 4 , the fault category includes the second fault category, according to the fault category of the work index parameter, the water pump 200 is controlled to work, including:

[0097] According to the second fault category, the water pump 200 is controlled to be shut down due to a fault.

[0098] Exemplarily, the air conditioner 1000 includes a main controller. Control water pump 200 failure shutdown, including:

[0099] The main controller controls the water pump 200 to shut down in case of failure.

[0100] It can be understood that the main controller can send a start signal and / or a shutdown signal to control the water pump 200 to start and / or shut down.

[0101] Exemplarily, the air conditioner 1000 further includes a liquid level sensor, and the liquid level sensor is signal-connected with the main controller for detecting the liquid level of the condensed water in the water receiving tray 400 . After the liquid level in the water receiving tray 400 ...

Abstract

The embodiment of the invention discloses a drainage fault control method of an air conditioner and the air conditioner. The air conditioner comprises a shell, a water pan, a water pump and a controller. The water pump is arranged above the water pan and used for discharging condensate water in the water pan. The main controller is in signal connection with the water pump. When the air conditioner works, water begins to be accumulated in the water pan, and the main controller controls the water pump to be started. The controller obtains working index parameters of the water pump and determines whether the water pump breaks down or not according to the working index parameters. And if the working index parameters are not in the preset index parameter range, determining fault categories of the water pump according to the types of the working index parameters, and controlling the water pump to perform different subsequent processing works according to different fault categories. According to the technical scheme, different treatment modes are carried out on different fault types, stable operation after the water pump breaks down is guaranteed, and the drainage stability of the air conditioner is improved.

Description

technical field [0001] The present application relates to the technical field of air conditioners, in particular to an air conditioner drainage fault control method and the air conditioner. Background technique [0002] In air conditioners, refrigerators and other electrical appliances that can produce condensed water, there are often situations where the condensed water cannot be discharged directly by gravity. It is necessary to use a water pump to discharge the accumulated condensed water in the air conditioner, so as not to affect the normal operation of the air conditioner. [0003] At present, the air conditioners on the market generally use AC water pumps, but the motor torque of AC water pumps is small, it is difficult to start, the speed of the water pump fluctuates when the water pump is expected to be heavy load, and even the motor performance is abnormal. In addition, the noise of the AC motor is large, the vibration of the motor is obvious, and the operation flu...
