Embodiment 1

[0028] According to an embodiment of the present invention, an embodiment of a method for detecting an air conditioner motor is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0029] figure 1 It is a flowchart of a method for detecting an air conditioner motor according to an embodiment of the present invention, such asfigure 1 As shown, the method includes the following steps:

[0030] Step S102, if the rotational speed fluctuation value of the air conditioner motor is less than the rotational speed fluctuation threshold, obtain the current operating data of the air conditioner motor;

[0031] Step S104, if the air conditioner motor needs to be detected, output a ...

Embodiment 2

[0090] According to an embodiment of the present invention, an embodiment of a device for implementing the above method for detecting an air conditioner motor is also provided, Figure 5 is a schematic structural diagram of a device for detecting an air conditioner motor according to an embodiment of the present invention, as shown in Figure 5 As shown, the above-mentioned device for detecting the air conditioner motor includes: a first acquisition module 50, a processing module 52, a second acquisition module 54 and a determination module 56, wherein:

[0091] The first acquisition module 50 is used to acquire the current operating data of the air conditioner motor when the speed fluctuation value of the air conditioner motor is less than the speed fluctuation threshold; the processing module 52 is used to output the data when the above air conditioner motor needs to be detected. The control signal for controlling the speed is sent to the above-mentioned air-conditioning mot...

Abstract

The invention discloses a method and device for detecting an air conditioner motor. The method comprises the steps that on the condition that a rotation speed fluctuating value of the air conditionermotor is smaller than a rotation speed fluctuating threshold value, current running data of the air conditioner motor are acquired; on the condition that the air conditioner motor needs to be detected, a control signal used for controlling the rotation speed is output to the air conditioner motor, and the load of the air conditioner motor is controlled through load interference amount control; feedback data of the air conditioner motor under the control signal and load interference amount control are acquired; and whether the air conditioner motor is released from cross-flow fan blades in an air conditioner or not is determined according to the current running data, the load interference amount and the feedback data. According to the method and device for detecting the air conditioner motor, the technical problems that an air conditioner indoor unit does not output air due to the fact that the air conditioner motor runs in a released mode, and meanwhile related load parts are very prone to being mechanically damaged are solved.

Description

technical field [0001] The invention relates to the field of motor detection, in particular to a method and device for detecting an air conditioner motor. Background technique [0002] In the prior art, the air conditioner controls the speed of the air conditioner motor through the feedback of the speed of the air conditioner motor to achieve closed-loop control, but the feedback signal of the air conditioner motor can only reflect the speed value, and the feedback signal cannot make the air conditioner controller perceive Check whether the motor of the air conditioner is in normal working condition, or it has tripped with the cross-flow fan blade and is in the no-load condition. [0003] Moreover, because the air conditioner motor trips and runs, the air conditioner internal unit will not produce air, and at the same time, it is very easy to cause mechanical damage to related load components, which may cause safety hazards in severe cases. [0004] For the above problems, ...
