DETAILED DESCRIPTION

[0034] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0036] It should be noted that like reference numerals and characters refer to like elements throughout the following figures and description, and thus, once certain terminologies are defined in one figure, they do not need to be further defined and explained in the subsequent figures.

[0037] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed during use, and are merely for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] In addition, the terms "horizontal", "vertical", and the like do not mean that the components must be absolutely horizontal or vertical, but can be slightly inclined. For example, "horizontal" only means that it is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0039] In the description of the present application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "provided", "mounted", "connected", "linked" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be mechanically connected, can be electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, or can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0040] At present, the air intake module of the vehicle-mounted air conditioner is provided in a horizontal manner, that is, the opposite sides of the air intake module are respectively the vehicle interior air intake side and the vehicle exterior air intake side. When the mixed air intake mode is used, the vehicle interior air enters the inlet of the air blower from the vehicle interior air intake side, the vehicle exterior air enters the inlet of the air blower from the vehicle exterior air intake side, and the mixed air is delivered by the air blower to the air conditioner to participate in heat exchange. Since the two are horizontally arranged, there is a counterattack situation. In order to adjust the ratio of the vehicle interior air and the vehicle exterior air, the position of the mixed air door needs to be rotated. After the position of the mixed air door is adjusted, the vehicle exterior air is easy to enter the vehicle interior air intake side and then enter the vehicle interior. If the vehicle exterior air is cold air, it is easy to affect the temperature environment in the vehicle interior, causing discomfort to the passengers.

The outside air can enter the fan-shaped air door from the first air inlet and be blocked by the plate-shaped air door, and under the blocking of the plate-shaped air door, the outside air directly enters the ventilation port and then enters the air outlet 101 to be sucked by the air blower and sent into the air conditioner. Similarly, the inside air can enter the fan-shaped air door from the second air inlet and be blocked by the plate-shaped air door, and the inside air can enter the ventilation port and then enter the air outlet 101 to be sent into the air conditioner under the action of the air blower. By adjusting the position of the fan-shaped air door between the first air inlet and the second air inlet and adjusting the position of the plate-shaped air door between the first air inlet side 216 and the second air inlet side 217, the inside-outside air inlet amount can be adjusted, and when the fan-shaped air door and the plate-shaped air door are in any position in the inside-outside mixed air inlet mode, the outside air is blocked by the plate-shaped air door and is not easy to enter the vehicle, so as not to easily affect the temperature environment in the vehicle.
