It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The remote control terminal 102 is wirelessly connected with the air conditioner 104, a user operates on the remote control terminal 102 side, when the user thinks that the air conditioner 104 needs to be self-cleaned, the user presses a self-cleaning button on the remote control terminal 102, the remote control terminal 102 sends a self-cleaning instruction to the air conditioner 104, and the air conditioner 104 responds to the self-cleaning instruction of the air conditioner; detecting the current environment temperature and humidity, and determining the dew point temperature of the current environment according to the current environment temperature and humidity; acquiring the temperature of the indoor evaporation assembly pipe in the self-cleaning condensation stage according to the dew point temperature; and controlling the output frequency of the compression assembly according to the temperature of the pipe. .
In one embodiment, as shown in fig. 2, there is provided a self-cleaning method for an air conditioner, which is described by taking the method as an example for the air conditioner in fig. 1, and comprises the following steps:
s200: responding to the self-cleaning command of the air conditioner.
The air conditioner self-cleaning instruction is used for indicating that the air conditioner needs to perform self-cleaning operation at present, namely the air conditioner enters a self-cleaning working condition. Specifically, the air conditioner self-cleaning instruction may be sent by a user operating a remote control terminal, or may be a self-cleaning period set by the user, for example, once in half a month or once in a month.
S400: and detecting the current environment temperature and humidity, and determining the dew point temperature of the current environment according to the current environment temperature and humidity.
The method comprises the steps of detecting the current ambient temperature and humidity, specifically detecting the current ambient temperature and humidity through a sensor, acquiring multiple groups of ambient temperature and humidity data in a periodic repeated detection mode in the detection process, generating an ambient temperature and humidity data set, rejecting the maximum value array and the minimum value array in the data set, and calculating the average value of the remaining arrays to obtain the accurate current ambient temperature and humidity. And further determining the dew point temperature of the current environment according to the environment temperature and the environment humidity.
The dew point temperature is the temperature of air cooled to saturation under the condition that the water vapor content and the air pressure are not changed, and is in a form of words, the temperature when the water vapor in the air becomes dew is called the dew point temperature, and the condition that the air temperature is reduced below the dew point is the necessary condition for water vapor condensation. Specifically, according to the environmental temperature and the humidity, the corresponding environmental dew point temperature can be determined and obtained through a table look-up mode, namely, a corresponding relation table of the environmental temperature, the humidity and the environmental dew point temperature can be constructed according to experiment/historical experience, and when the dew point temperature of the current environment needs to be determined, the dew point temperature of the current environment is directly determined according to the current environmental temperature and the humidity table look-up.
S600: and acquiring the temperature of the indoor evaporation assembly pipe in the self-cleaning condensation stage according to the dew point temperature.
And further determining the temperature of the indoor evaporation assembly pipe in the clean dew-forming stage according to the dew point temperature. Specifically, the indoor evaporation assembly refers to an air-conditioning indoor evaporator, a refrigerant exchanges heat with the environment in the air-conditioning indoor evaporator to absorb heat in the environment, so that the temperature of the surface of the evaporator is reduced, and water vapor in the air is condensed into water drops to be collected in a receiving disc of the air conditioner when meeting the surface of a pipeline of the evaporator. The temperature of the evaporator is reasonably determined according to the dew point temperature, so that water vapor in the air can be effectively condensed into water drops under the condition of the least refrigerating capacity, and the energy consumption is reduced while the effective condensation is realized. Here, the tube temperature of the indoor evaporation assembly in the self-cleaning condensation stage can be obtained according to the dew point temperature by means of a table look-up. Specifically, for a certain type of air conditioner, the corresponding pipe temperature and dew point temperature correction constants of the air conditioner under different wind gears can be determined in an experimental data analysis mode, and when the pipe temperature needs to be determined, the correction constant corresponding to the current wind gear is only needed to be identified, and then the pipe temperature of the evaporation assembly is determined according to the dew point temperature and the correction constant.

The compression component is specifically a compressor in the air conditioner, and the output frequency of the compressor is controlled, so that the energy consumption of the air conditioner can be adjusted/controlled. The output frequency of the compression assembly is reasonably controlled according to the temperature of the pipe, so that the condensation self-cleaning can be realized, and meanwhile, the unified output aiming at different environmental conditions is avoided, and the purpose of saving energy is achieved. The output frequency of the compression assembly can be determined according to the tube temperature by adopting a table look-up mode, the most basic output frequency of reasonable compression corresponding to the tube temperature can be tested and verified in an experimental state, a tube temperature-output frequency corresponding relation table is constructed, reasonable output frequency is obtained according to the tube temperature and the tube temperature-output frequency corresponding relation table in actual application, and the compression assembly is controlled to work according to the reasonable output frequency, so that the effective self-cleaning function is realized, the energy consumption can be reduced, and the purpose of energy conservation is achieved.

In the whole process, the dew point temperature which is in accordance with the current environment condition is determined according to the current environment temperature and the current environment humidity, so that the proper pipe temperature is obtained, and the output power frequency of the compression assembly is controlled based on the proper pipe temperature, so that the self-cleaning operation of the whole air conditioner can be adaptively adjusted according to the environment condition, and the purpose of energy conservation is achieved.
As shown in fig. 3, in one embodiment, after S200, the method further includes:
s320: detecting the water level in the water pan;
s340: and when the water level in the water pan is lower than the preset warning water level, starting a self-cleaning function, and entering a step of detecting the current environmental temperature and humidity.

In addition, since the air conditioner may generate more condensed water in the self-cleaning mode, which may cause a great increase in the water level in the water pan, if a proper water storage space is not prepared in advance, the condensed water may overflow the upper edge of the water pan, overflow the air conditioning unit, destroy the room, and the like. If the water level in the water pan is not lower than the preset warning water level, the water pumping function of the water pan is started, namely, the drainage water pump is controlled to work, so that the condensed water in the water pan is pumped and discharged outdoors.
In practical application, the water level of a water receiving disc of the indoor unit is detected in real time, and if the water level of the indoor unit does not reach the warning water level, a water pump of the indoor unit is always in a closed state; if the water level of the indoor unit water pan reaches the warning water level, a water pump of the indoor unit is started, the water level of the indoor unit water pan is detected in real time while the water pump is started, and when the water level is lower than the warning water level, the currently running water pump is closed to stop draining; therefore, the indoor unit can be guaranteed to have a certain water volume in the indoor water receiving tray when being self-cleaned, and the situation that the water volume of the water receiving tray overflows the unit excessively to destroy a suspended ceiling and the like of a room can be avoided.
