Embodiment 1

[0025] Such as figure 2As shown, the step of "judging whether to implement the self-cleaning mode for the outdoor unit according to the fan current of the outdoor unit and the exhaust temperature of the compressor" includes: calculating the ratio of the fan current of the outdoor unit to the standard current value and the first preset value Comparison; if the ratio is less than the first preset value, compare the difference between the discharge temperature of the compressor and the standard discharge temperature with the second preset value; according to the comparison result, determine whether to implement the self-cleaning mode for the outdoor unit. If the ratio is not less than the first preset value, the self-cleaning mode is not performed on the outdoor unit. The step of "judging whether to execute the self-cleaning mode on the outdoor unit according to the comparison result" includes: if the difference between the discharge temperature of the compressor and the standar...

Embodiment 2

[0027] As another modification of the first embodiment, the step of "judging whether to execute the self-cleaning mode for the outdoor unit according to the fan current of the outdoor unit and the discharge temperature of the compressor" includes: comparing the discharge temperature of the compressor with the standard discharge temperature The temperature difference is compared with the second preset value; if the difference between the discharge temperature of the compressor and the standard discharge temperature is smaller than the second preset value, the ratio of the fan current of the outdoor unit to the standard current value and the first Preset value comparison; according to the comparison result, it is judged whether to execute the self-cleaning mode for the outdoor unit. If the difference between the discharge temperature of the compressor and the standard discharge temperature is not less than the second preset value, the self-cleaning mode is not executed on the out...

Abstract

The invention belongs to the technical field of air conditioners, and aims to solve the problem that if the existing air conditioners are judged by a single condition of the fan current of an outdoor unit, the air conditioner is likely to frequently execute a self-cleaning mode due to misjudgment. Therefore, the present invention provides a self-cleaning control method for an air conditioner, the air conditioner includes an outdoor unit and a compressor, the self-cleaning control method includes: obtaining the fan current of the outdoor unit and the exhaust temperature of the compressor; According to the fan current of the outdoor unit and the exhaust temperature of the compressor, determine whether to implement the self-cleaning mode for the outdoor unit. The present invention judges through the combination of the discharge temperature of the compressor and the current of the fan of the outdoor unit, so that the air conditioner does not frequently execute the self-cleaning mode due to the fluctuation of the fan current of the outdoor unit due to misjudgment.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a self-cleaning control method for an air conditioner. Background technique [0002] The air conditioner is a device that can cool / heat the room. As time goes by, the dust accumulation on the indoor and outdoor units of the air conditioner will gradually increase. After the dust accumulation reaches a certain level, a large number of bacteria will grow. Since the indoor unit of the air conditioner and the outdoor unit of the air conditioner are always installed outdoors (specifically, on the outer wall of the building), the accumulation rate of dust is obviously higher than that of the indoor unit, so the outdoor unit of the air conditioner needs to be cleaned in time. [0003] In the prior art, the cleaning methods of the air conditioner include manual cleaning and self-cleaning of the air conditioner. It is time-consuming and labor-intensive to use manual clea...
