The first air inlet 113 may be disposed on any wall of the housing 11 corresponding to the first internal cavity unit 13, and the first air inlet 113 corresponding to the first internal cavity unit 13 refers to that the first air inlet 113 is disposed on a side wall of the housing 11 that participates in enclosing to form the first internal cavity unit 13, so that the first air inlet 113 is directly communicated with the first internal cavity unit 13. For example, in the embodiment shown in fig. 1, the first intake vent 113 may be provided on the side wall 112 or the end plate 111 surrounding the portion forming the first internal chamber unit 13.
A second air inlet 114 corresponding to the second internal cavity unit 14 is further disposed on the side wall of the housing 11, and the external air flow can enter the second internal cavity unit 14 through the second air inlet 114. The second air inlet opening 114 may be disposed on any wall of the housing 11 corresponding to the second internal cavity unit 14, and the second air inlet opening 114 corresponding to the second internal cavity unit 14 refers to the second air inlet opening 114 disposed on the side wall of the housing 11 that participates in enclosing to form the second internal cavity unit 14, so that the second air inlet opening 114 is directly communicated with the second internal cavity unit 14. For example, in the embodiment shown in fig. 1, the second air inlet opening 114 may be disposed on the side wall 112 or the end plate 111 surrounding the portion forming the second internal chamber unit 14.
The air guide assembly 12 includes an air guide plate 121 movable between a first position and a second position, and the flow path of the air flow is changed by changing the position of the air guide plate 121. Specifically, the air deflection plate 121 includes a first air deflection plate portion 1211, a second air deflection plate portion 1212, and a third air deflection plate portion 1213. The first air guiding plate 1211 is a full panel and has a shape matching the second opening. The second air guide plate portion 1212 is provided with a ventilation opening 1212a, that is, the second air guide plate portion 1212 has a plate-like structure as a whole, and the ventilation opening 1212a is provided in the plate-like structure as a whole. The third air guide plate portion 1213 is a full panel and has a shape adapted to the first open portion. The whole panel herein refers to a structure having an integral plate shape, and no holes, slits, or the like through which a fluid can pass are provided.

In one embodiment, the motor 123 is a stepper motor, and the position of the air deflector 121 is controlled by controlling the number of steps of the motor 123. Specifically, the first position is set as a reset position of the motor 123, and the motor 123 stops moving after a predetermined number of steps of the motor 123 advances along the first direction, so that the motor 123 drives the air deflector 121 to move to the second position. When the air path needs to be switched, the motor 123 is controlled to move for a predetermined number of steps in a second direction opposite to the first direction, and then the motor 123 stops moving, so that the air deflector 121 is driven by the motor 123 to move to the first position.
Of course, it is understood that in embodiments where the air deflection plate 121 has a first position, a second position, a third position, and a fourth position, the movement of the air deflection plate 121 may also be controlled in a manner similar to that described above.
