In other embodiments, the fresh air device 600 may be provided with a fresh air wind wheel corresponding to the fresh air flow path, and a moisture removal wind wheel corresponding to the moisture removal flow path, and the fresh air wind wheel is started when the fresh air device 600 is in the fresh air state, and the moisture removal wind wheel is started when the fresh air device 600 is in the moisture removal state, so that the fresh air device 600 is switched between the fresh air state and the moisture removal state.

Specifically, in this embodiment, please continue to refer to fig. 8 to 11, the wind wheel is set as a centrifugal wind wheel 680, the fresh air outlet 610 is set corresponding to the radial direction of the centrifugal wind wheel 680, the dehumidifying flow path includes an air inlet section 601 disposed between the wet air inlet 620 and the centrifugal wind wheel 680, and an air outlet section 602 disposed between the air exchanging port 630 and the centrifugal wind wheel 680, the air inlet section 601 and the air outlet section 602 are communicated with the same axial side of the centrifugal wind wheel 680, a communication port 670 is disposed between the two, and the fresh air device 600 further includes a fourth valve 660 disposed corresponding to the communication port 670; in the fresh air state, the fourth valve 660 opens the communication port 670, and in the moisture removal state, the fourth valve 660 closes the communication port 670. It can be appreciated that, in the moisture removal state, the air outlet section 602 is used for discharging moisture from the centrifugal wind wheel 680 towards the ventilation port, and in the fresh air state, the air outlet section 602 is used for delivering air from the ventilation port towards the centrifugal wind wheel 680, so that when the fresh air device 600 is in the fresh air state, the air enters the air outlet section 602 from the ventilation port, one part enters the centrifugal wind wheel 680 from the communication position between the air outlet section 602 and the centrifugal wind wheel 680, the other part enters the centrifugal wind wheel 680 from the communication position between the air inlet section 601 and the centrifugal wind wheel 680 through the communication port 670, and the centrifugal wind wheel 680 then delivers fresh air into a room from the fresh air outlet 610 in the radial direction thereof, thereby avoiding the influence of the original fresh air delivery capacity due to the addition of a moisture removal flow channel; when the fresh air device 600 is in a moisture-discharging state, moisture enters the air inlet section 601 from the wet air inlet 620 and enters the centrifugal wind wheel 680 from the communication position of the air inlet section 601 and the centrifugal wind wheel 680, and the third valve 650 closes the fresh air outlet 610, so that the centrifugal wind wheel 680 conveys the moisture to the air outlet section 602 and then discharges the moisture outdoors, and the fourth valve 660 closes the communication opening 670, thereby avoiding the circulating flow of the wet air among the air inlet section 601, the centrifugal wind wheel 680 and the air outlet section 602 and ensuring the discharge efficiency of the moisture. In other embodiments, the communication between the air outlet segment 602 and the centrifugal wind wheel 680 is large enough, so that the communication between the air outlet segment 602 and the centrifugal wind wheel 680 can meet the requirement for the air volume when the fresh air is introduced, and the air inlet segment 601 and the air outlet segment 602 are independent from each other and are not communicated by the communication port 670.

Further, in the present embodiment, referring to fig. 10 and 11, the air outlet section 602 is provided with a volute 690 to form a tapered and expanding moisture air outlet flow path. Without loss of generality, the volute 690 is disposed adjacent to the communication between the air outlet segment 602 and the centrifugal wind wheel 680, so that in the dehumidifying state, moisture enters the air outlet segment 602 from the centrifugal wind wheel 680, and the volute 690 adjusts the air outlet segment 602 into a tapered and gradually-expanding flow path, so that the effect of pressurizing the moisture can be achieved, and the discharge of the moisture from the air exchanging port 630 is promoted. In other embodiments, an axial flow wind wheel may be disposed at the air exchanging port 630, when the fresh air device 600 is in a fresh air state, the axial flow wind wheel rotates forward, air enters the air outlet section 602 from the air exchanging port 630, when the fresh air device 600 is in a moisture removing state, the axial flow wind wheel rotates reversely, and moisture is discharged from the air outlet section 602 through the air exchanging port 630.

In an embodiment, referring to fig. 1 and 8, the air conditioner includes an indoor unit and an outdoor unit, the casing 100 is the casing 100 of the indoor unit, and the air inlet 120 and the dehumidifying element 200 are disposed in the indoor unit. In other embodiments, the air conditioner may be provided as a unitary air conditioner, and the specific structure of the unitary air conditioner is also referred to the above embodiments.

The foregoing description is only of the optional embodiments of the present utility model, and is not intended to limit the scope of the utility model, and all the equivalent structural changes made by the description of the present utility model and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the utility model.
