In the present embodiment, the air conditioner cleaning method may be optionally applied to an air conditioner cleaning system.
The air conditioner cleaning method includes:
and step S10, detecting whether the operation time of the air conditioner is greater than a preset cleaning time.
When the air conditioner is powered on, the air conditioner automatically detects the running time of the air conditioner in real time and judges whether the running time is greater than the preset cleaning time. The preset cleaning time is an empirical value determined by a worker according to the use condition of the air conditioner, and the preset cleaning time corresponding to different types of air conditioners may be the same or different. Specifically, when the air conditioner detects the current operation time of the air conditioner, the air conditioner calculates a difference between the operation time and the preset cleaning time, that is, subtracts the preset cleaning time from the operation time to obtain a corresponding difference, and determines whether the difference is greater than zero. It is understood that when the difference is greater than zero, it indicates that the operation time of the air conditioner is greater than the preset cleaning time.
Further, when the operation time of the air conditioner is less than or equal to the preset cleaning time, the air conditioner continues to detect whether the operation time is greater than the preset cleaning time.
Step S20, if the operation time is greater than the preset cleaning time, switching the current operating mode of the air conditioner to a cleaning mode to trigger a cleaning instruction.
If the running time of the air conditioner is detected to be larger than the preset cleaning time, the air conditioner switches the current working mode of the air conditioner to the cleaning mode so as to automatically trigger a cleaning instruction. If the current working mode of the air conditioner is the refrigeration mode, the air conditioner switches the refrigeration mode to the cleaning mode; if the current working mode of the air conditioner is the heating mode, the air conditioner switches the heating mode to the cleaning mode.

The first heat exchanger and the second heat exchanger have the effects of absorbing and releasing heat in the running process of the air conditioner. If in the air conditioner refrigeration process, first heat exchanger plays the heat absorption effect, and the second heat exchanger plays exothermic, then in the heating process, first heat exchanger plays exothermic, and the second heat exchanger plays the heat absorption effect.

In this embodiment, the first spraying device may be a spraying plate or a spraying bar, and a predetermined number of spraying openings are provided on the first spraying device, through which the cleaning agent may be sprayed onto the fin surface of the first heat exchanger.

In this embodiment, the second spraying device may be a spraying plate or a spraying bar, and a predetermined number of spraying openings are provided on the second spraying device, through which the cleaning agent may be sprayed onto the fin surface of the second heat exchanger.

Further, in order to facilitate a user to replenish the detergent in the detergent box in time, the air conditioner may detect the amount of detergent in the detergent box through a water level gauge or other detection means. When the height of the detergent in the detergent box is smaller than or equal to the preset height, the air conditioner outputs alarm information to prompt a user that the detergent amount in the detergent box is small and the user needs to replenish the detergent in time. The preset height may be set according to specific needs, and the preset height is not specifically limited in this embodiment.
Further, a second embodiment of the cleaning method of the air conditioner of the present invention is provided.
The second embodiment of the air conditioner cleaning method is different from the first embodiment of the air conditioner cleaning method in that the air conditioner cleaning method further includes:
and e, controlling a motor corresponding to the first heat exchanger to be in a stop state, and controlling a four-way valve of the air conditioner to be in a power-off state, so that the surface of the fins of the first heat exchanger is frosted.
After the air conditioner triggers a cleaning instruction, the air conditioner controls the motor corresponding to the first heat exchanger to be in a stop state, namely, in a non-rotating state, and controls the four-way valve to be in a power-off state, and controls the motor corresponding to the second heat exchanger and the compressor to be in a running state, so that frost is condensed on the surface of the fins of the first heat exchanger. Specifically, when the four-way valve is in a power-off state, the air conditioner is in a refrigeration mode, the compressor of the air conditioner is powered on to run, and a refrigerant of the air conditioner is controlled to flow through the four-way valve, the second heat exchanger, the capillary tube, the first heat exchanger and the compressor to be reflowed to the surface of the fins of the first heat exchanger.
And f, calculating a first frost forming time of the first heat exchanger.
And g, if the first frost forming time length is greater than a first preset time length, triggering a first spraying instruction.
The air conditioner calculates the time for the first heat exchanger fin surface to frost, records the time for the first heat exchanger fin surface to frost as a first time for frost, and judges whether the first time for frost is greater than a first preset time. If the first frost forming time length is longer than a first preset time length, the air conditioner automatically triggers a first spraying instruction. If the first frost forming time length is less than or equal to a first preset time length, the air conditioner continuously judges whether the first frost forming time length is greater than the first preset time length. The first preset time is an empirical value obtained through testing. The process that the air conditioner judges whether the first frost forming time length is greater than the first preset time length is as follows: and the air conditioner subtracts the first preset time length from the first defrosting time length to obtain a corresponding difference value. When the difference is greater than zero, determining that the first frost condensation time length is greater than a first preset time length; when the difference is less than or equal to zero, determining that the first frost forming time period is equal to or less than a first preset time period.

After the air conditioner triggers the first spraying instruction, the air conditioner controls the spraying opening of the first spraying device to spray the cleaning agent on the surface of the fin of the first heat exchanger through the first spraying instruction. After the cleaning agent is sprayed on the surfaces of the fins of the first heat exchanger, the air conditioner controls the four-way valve to be in a power-on state and controls the motor corresponding to the first heat exchanger to be in a running state, so that the frost on the surfaces of the fins of the first heat exchanger is melted into water, and the water and the cleaning agent are used for washing dirt on the surfaces of the fins of the first heat exchanger, namely washing dust, micro impurities and the like on the surfaces of the fins of the first heat exchanger, so as to clean the first heat exchanger.
