Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile air conditioning systems, in particular to an air door device, an air conditioner, a vehicle and a cleaning method. BACKGROUND

[0002] When the automobile air conditioning system is used for a long time without cleaning, an unpleasant smell such as mold smell is often smelled when the automobile air conditioner is turned on, and the evaporator in the air conditioner is a main component in which mold is easily grown and then mold smell is generated. In the market practice of the automobile air conditioning industry, it is found that mold growth on the evaporator cannot be avoided for almost all automobile air conditioning systems, and therefore it is necessary to clean the automobile air conditioning system regularly or irregularly.

[0003] At present, one of the most commonly used methods for cleaning the automobile air conditioning system is direct cleaning with an automobile air conditioner cleaner. This method requires that the air conditioner filter be removed, the automobile air conditioner cleaner in foaming form be sucked from the air inlet of the air blower, and the air outlet of the instrument panel be closed tightly (to prevent the automobile air conditioner cleaner from flowing out of the air outlet). Due to the blockage of the air conditioner box body air duct and various structures of the air blower, the evaporator surface cannot be cleaned in all directions, which will greatly reduce the effect of removing bacteria and mold.

[0004] Comparative document 1 (CN 210108133 U) discloses an air conditioning system and a vehicle. The air conditioning system comprises a casing, an evaporator, a temperature air door and an evaporator cleaning assembly arranged in the casing. The evaporator cleaning assembly comprises a first cleaning nozzle, the first cleaning nozzle is fixedly arranged with the temperature air door, and the liquid outlet direction of the first cleaning nozzle is towards the evaporator. Although this scheme realizes self-cleaning of the evaporator, the cleaning nozzle is separately arranged on the temperature air door, which changes the center of gravity of the air door shaft, further changes the driving requirement, increases the energy consumption, reduces the balance and stability of the temperature air door, and easily brings greater noise during use of the air conditioner, thereby reducing the user experience.

[0005] Comparative document 2 (CN 212353526 U) discloses an automobile air conditioner with a cleaning structure. The automobile air conditioner comprises an internal and external circulation air door, an air conditioner filter, an intermediate transition air duct, an air blower, an evaporator, a cold and warm mixed air door and a warm air core body, and further comprises a cleaning plug cover. The intermediate transition air duct between the air blower and the evaporator is provided with a cleaning hole on the outer side. The cleaning plug cover seals the cleaning hole. The automobile air conditioner sends air through the air blower of the automobile air conditioner, so that the automobile air conditioner cleaner (or air conditioner bactericide, etc.) flows through the entire automobile air conditioner and the air duct, etc., thereby cleaning the entire automobile air conditioning system. However, this scheme cannot avoid the problem that the evaporator surface cannot be cleaned in all directions due to the blockage of the air conditioner box body air duct and various structures of the air blower.

[0006] At present, there is no effective solution to the above problems. SUMMARY

[0092] 2. The processing method is simpler, can improve the cleaning effect without additional energy consumption, is more economical and practical, and can improve the user's use experience.

[0093] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0094] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this application.

[0095] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0096] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
