Referring to fig. 1, the present invention provides a method for detecting an abnormal closing and jamming of an air deflector assembly, which is suitable for an air conditioner, and the method includes steps S110 to S230.
In step S110, the air conditioner starts.
And step S120, the air conditioning unit normally operates.
And step S130, judging whether the rotating speed of the indoor fan of the air conditioner fluctuates abnormally or not.
If the result of the step S130 is yes, the step S140 is started.
When the step S130 is executed in the negative, the step S120 is started.
Specifically, in this embodiment, after the setting of the rotational speed of the fan is completed and the actual operation of the fan is stable, the rotational speed of the fan may slightly fluctuate above and below the set value, where an abnormal fluctuation refers to a large fluctuation suddenly appearing above and below the set value under normal conditions, for example, the set value is 1200, the actual operation range ± R of the fan after stabilization is normal conditions, and if the rotational speed is not adjusted, the fluctuation exceeds the range, the rotational speed is abnormal. The air conditioning unit is powered on and operates, after the indoor fan of the air conditioner is normally started, the detection module detects the rotating speed information of the indoor fan of the air conditioner, the judgment module judges whether the detected rotating speed signal of the indoor fan of the air conditioner has abnormal fluctuation or not, when the detected rotating speed signal of the indoor fan of the air conditioner has abnormal fluctuation, the control module starts to execute the step S140, and when the rotating speed signal of the indoor fan of the air conditioner acquired by the detection device has no abnormal fluctuation, the control module starts to execute the step S120.
And step S140, controlling the air guide plate assembly to run to a first preset position, and enabling the indoor fan of the air conditioner to rotate reversely for a preset time and then to recover to rotate normally.
The first preset position is a position where the air guide plate assembly is perpendicular to the air outlet.
Specifically, in this embodiment, the control module controls the air guide plate assembly to move to a position where air blowing is most smooth, and enables the indoor fan of the air conditioner to rotate reversely for a preset time and then to return to normal, and the air guide plate assembly includes a horizontal air guide plate and a vertical air guide plate.
The air conditioner is provided with an air inlet, a heat exchange device, a blowing device, an indoor fan, an air outlet, an air guide device and an air deflector, wherein air fluid is sucked from the air inlet under the action of the blowing device, the temperature of the air fluid is adjusted through the heat exchange device, the air fluid with the adjusted temperature is sent out from the air outlet, and the air deflector assembly is arranged at the air outlet to adjust the blowing angle.
In the normal operation process of the air conditioner, the smooth flow of air fluid at the air inlet and the air outlet of the air conditioner needs to be ensured. Under the condition that air fluid flowing in and out of the air conditioner is smooth, the fluctuation of the rotating speed of an indoor fan of the air conditioner is very small, and the indoor fan stably runs within a set value range; under the condition of non-adjustment of the rotating speed, when the air inlet or the air outlet is blocked by something, abnormal data can appear in the rotating speed value of the indoor fan of the air conditioner, and the indoor fan of the air conditioner can have larger rotating speed fluctuation. Therefore, when the fan in the air conditioning room fluctuates abnormally, the air inlet may be blocked or the air outlet may be blocked.
The reason for the blockage of the air inlet can be that some objects floating in the air are adsorbed on the filter screen of the air inlet, and the blockage of the air outlet can be caused by the abnormal closing and blocking of the air deflector assembly. The air guide plate assembly is controlled by the control module to move to the position where the air conditioner blows air most smoothly, the air conditioner indoor fan rotates reversely at the maximum limit rotating speed for a period of time, the original air inlet becomes the air outlet, the original air outlet becomes the air inlet, and the air conditioner indoor fan rotates reversely at the maximum limit rotating speed to clean the filter screen of the original air inlet.

Specifically, the detection module detects the rotating speed of the indoor fan of the air conditioner, the judgment module judges whether the rotating speed of the indoor fan of the air conditioner fluctuates abnormally or not, the indoor fan of the air conditioner recovers to rotate normally after rotating reversely for a period of time, the rotating speed of the indoor fan of the air conditioner fluctuates abnormally, which indicates that the abnormal fluctuation of the rotating speed of the fan in the forward rotation is not caused by the floating objects absorbed by the air inlet, the reason of the abnormal fluctuation of the rotating speed of the fan needs to be further judged, and the step S160 is executed.
And when the fan in the air conditioning room reversely rotates for a period of time and then normally rotates, and the rotating speed of the fan in the air conditioning room does not have abnormal fluctuation, the air deflector assembly of the air conditioner is normal, the abnormal fluctuation of the rotating speed during the forward rotation of the fan is caused by floaters adsorbed by the air inlet, the floaters blocked at the air inlet are blown away when the fan in the air conditioning room reversely rotates at the maximum limit rotating speed, the air conditioning unit can be normally operated, the step S170 is executed, and the step S170 is executed for the air conditioning unit to normally operate.
And step S160, recording the rotating speed fluctuation range of the indoor fan of the air conditioner when the air deflector assembly runs to a first preset position, and executing step S180.
And S180, controlling the air deflector assembly to operate to a second preset position, recording the rotating speed fluctuation range of the indoor fan of the air conditioner when the air deflector assembly operates to the second preset position, and executing S190.
The second preset position is a position where the air guide plate assembly is parallel to the air outlet.
And step S190, judging whether the fluctuation range of the rotating speed of the indoor fan of the air conditioner recorded twice has deviation.
When the execution result of step S190 is yes, step S200 is started.
When the execution result of step S190 is no, step S170 is started.
Specifically, in this embodiment, when the information module records that the control module controls the air guide plate assembly to move to the position where air is blown most smoothly, the fluctuation range of the rotating speed of the indoor fan of the air conditioner and the fluctuation range of the rotating speed of the indoor fan of the air conditioner recorded when the control module controls the air guide plate assembly to move to the position where air is blown most smoothly under the condition that other variables of the air conditioner are not changed. The judging module judges whether the fluctuation range of the rotating speed of the indoor fan of the air conditioner recorded twice has deviation, if the fluctuation range of the rotating speed of the indoor fan of the air conditioner recorded twice has deviation, the air deflector assembly of the air conditioner can normally operate under the control of the control module, and then the air deflector assembly is abnormal-free, and the air conditioning unit normally operates. If the rotation speed fluctuation range of the indoor fan of the air conditioner recorded twice is not deviated, it is indicated that the air deflector assembly of the air conditioner cannot normally operate under the control of the control module, and further, the air deflector assembly is abnormal, and the step S200 is started to be executed.
And step S200, stopping the air conditioning unit, starting the air conditioning unit after executing a reset instruction, and executing step S210.
And step S210, judging whether the rotating speed of the indoor fan of the air conditioner fluctuates abnormally.
When the execution result of step S210 is yes, step S220 is started to be executed.
When the execution result of step S210 is no, step S230 is started.
And step S220, the air conditioning unit is stopped, and the fault information of the air guide plate assembly is generated.
And step S230, the air conditioning unit recovers normal operation.
Specifically, after a reset instruction is executed once, the air conditioning unit is started, and the rotating speed of the indoor fan of the air conditioner normally fluctuates, it is indicated that the air deflector assembly of the air conditioner is repaired normally, and the air conditioning unit can continue to operate normally.
