Moreover, the air conditioner self-cleaning system is simple to operate, and can avoid the problems of long time consumption and high cost caused by manual cleaning of the evaporator 101.

In an alternative embodiment of the present invention, the washing device 13 may specifically include: a washing pump 131, a liquid storage tank 132, a liquid delivery pipe 133, a nozzle member 134, and a liquid level sensor 135; the liquid level sensor 135 is located in the liquid storage tank 132, and can be used for detecting the liquid level of the cleaning liquid in the liquid storage tank 132 to obtain a liquid level value.
The liquid pipe 133 is connected to the liquid reservoir 132, the washing pump 131 and the nozzle part 134 in this order.
The nozzle member 134 is opposite to the second side of the evaporator 101.
The controller 11 is respectively connected to the liquid level sensor 135 and the washing pump 131, and can be used for controlling the washing pump 131 to be turned on to perform a washing process on the evaporator 101 when the liquid level value meets a first preset condition.

In the embodiment of the present invention, a liquid level sensor 135 may be disposed in the liquid storage tank 132, and the liquid level sensor 135 may be configured to detect a liquid level of the cleaning liquid in the liquid storage tank 132 to obtain a liquid level value. In specific application, before the washing pump 131 is started, the liquid level sensor 135 can be controlled to detect the liquid level of the washing liquid in the liquid storage tank 132, when the liquid level value meets the first preset condition, the storage amount of the washing liquid in the liquid storage tank 132 can be considered to meet the washing requirement, under the condition, the washing pump 131 can be started, when the liquid level value does not meet the first preset condition, the storage amount of the washing liquid in the liquid storage tank 132 can be considered to not meet the washing requirement, under the condition, a user can be reminded to fill the washing liquid in the liquid storage tank 132 in a warning mode of sound, light or the like, and the washing pump 132 is prevented from being burnt out.
In practical applications, the first preset condition may be set according to actual conditions, for example, the first preset condition may be a cleaning amount of the cleaning liquid in the liquid storage tank 132 being three times, a cleaning amount of the cleaning liquid being five times, or the like. The first preset condition is not specifically limited in the embodiment of the present invention.
Specifically, the liquid pipe 133 is connected to the liquid storage tank 132, the washing pump 131 and the nozzle component 134 in sequence, so that the cleaning liquid in the liquid storage tank 132 can be conveyed into the washing pump 131, and then the cleaning liquid can be conveyed to the nozzle component 134 through the washing pump 131. In the embodiment of the present invention, since the nozzle component 134 is opposite to the second side of the evaporator 101, the nozzle component 134 can spray the cleaning liquid to cover the surface of the evaporator 101, so as to directly clean away the contaminants, microorganisms and harmful bacteria adhered to the evaporator 101, and the cleaning efficiency is high.
In the embodiment of the present invention, the first washing time of the washing device 13 may be set according to actual needs, and the first washing time may be 8 seconds, 10 seconds, 12 seconds, or the like. When the operation time of the washing pump 131 and the nozzle part 134 corresponds to the first washing time, the washing process of the evaporator 101 may be considered to be completed, and at this time, the washing pump 131 and the nozzle part 134 may be controlled to stop operating.
In another alternative embodiment of the present invention, the bacteriostatic device 14 may comprise: an ultraviolet sterilizing lamp 141; wherein the ultraviolet sterilizing lamp 141 is opposite to the second side of the evaporator 101.

In practical applications, since the ultraviolet disinfection lamp 141 can be used to kill bacteria propagules, spores, mycobacteria, coronaviruses, fungi, rickettsiae, chlamydia, etc., the ultraviolet disinfection can be used to disinfect the surfaces of objects, water and air contaminated by the above viruses. Moreover, the ultraviolet disinfection lamp 141 has the advantages of long service life and high disinfection efficiency, so in the embodiment of the invention, the ultraviolet disinfection lamp 141 is arranged opposite to the second side of the evaporator 101, so that substances such as microorganisms and harmful bacteria on the evaporator 101 can be killed, the disinfection efficiency is high, and the service life is long.
In the embodiment of the present invention, the ultraviolet disinfection time of the ultraviolet disinfection lamp 141 may be set according to actual needs, and the ultraviolet disinfection time may be 8 seconds, 10 seconds, 12 seconds, or the like. When the operation time of the ultraviolet sterilizing lamp 141 corresponds to the ultraviolet sterilizing time, it is considered that the ultraviolet sterilizing process of the evaporator 101 is completed, and at this time, the operation of the ultraviolet sterilizing lamp 141 may be controlled to be stopped.
In a specific application, when the air quality detected by the air quality sensor 12 is "poor", the controller 11 may automatically control the washing pump 131 to be turned on, spray the cleaning liquid through the nozzle part 134 to perform the washing process on the evaporator 101, and control the ultraviolet sterilizing lamp 141 to perform the bacteriostatic process on the evaporator 101.

The controller 11 is connected to the heating sheet 142, and is configured to control the heating sheet 142 to perform the bacteriostatic treatment on the evaporator 101 after the washing device 13 stops performing the washing treatment on the evaporator 101.
In practical applications, after the operation time of the washing pump 131 and the nozzle component 134 is matched with the first washing time, the washing process of the evaporator 101 is considered to be completed, and at this time, the operation of the washing pump 131 and the nozzle component 134 may be controlled to stop, and the washing process of the evaporator 101 may be stopped. Then, the heating sheet 142 is controlled to perform bacteriostatic treatment on the evaporator 101.
In the embodiment of the present invention, since the heating sheet 142 is opposite to the second side of the evaporator 101, the moisture on the evaporator 101 can be evaporated by the heat generated by the heating sheet 142, so that the environment where the evaporator 101 is located is relatively dry, and the growth of substances such as microorganisms and harmful bacteria on the evaporator 101 is suppressed.
In the embodiment of the present invention, the heating time of the heating sheet 142 may be set according to actual needs, and the heating time may be 8 seconds, 10 seconds, 12 seconds, or the like. When the operation time of the heating sheet 142 corresponds to the heating time, the bacteriostatic treatment of the evaporator 101 may be considered to be completed, and at this time, the operation of the heating sheet 142 may be controlled to stop.
In practical applications, the air conditioning system of the vehicle may further include: a blower 102; the controller 11 is connected to the blower 102, and may be configured to control the blower 102 to rotate in the first direction to draw air in the air conditioning system of the vehicle after the heater sheet 142 stops performing the bacteriostatic treatment on the evaporator 101.
In practice, when the blower 102 is rotated in the first direction, air within the air conditioning system of the vehicle may be drawn out, and correspondingly, when the blower 102 is rotated in a second direction opposite to the first direction, external air may be drawn into the air conditioning system and the vehicle. Specifically, the first direction and the second direction may be a clockwise direction and a counterclockwise direction, or a counterclockwise direction and a clockwise direction, and the specific directions of the first direction and the second direction are not limited in the embodiment of the present invention.
