The rotating shaft 253 is rotated, and the first valve plate 251 and the second valve plate 252 can synchronously rotate along with the rotating shaft 253; when the first valve plate 251 is disengaged from the opening of the first chamber 23, the second valve plate 252 seals the opening of the second chamber 24; and the second valve plate 252 is disengaged from the opening of the second chamber 24, the first valve plate 251 seals the opening of the first chamber 23.
For example, the angle between the first valve plate 251 and the second valve plate 252 may be 90 degrees. As shown in fig. 9, when the air conditioner is in the fresh air mode, in other words, when the valve plate assembly 25 is in the first state, the first valve plate 251 is parallel to or attached to the partition 22, and the second valve plate 252 rotates to the opening of the second chamber 24 and seals the opening of the second chamber 24.
As shown in fig. 10, when the air conditioner is in the indoor air circulation mode, in other words, when the valve plate assembly 25 is in the second state, the second valve plate 252 is parallel to or attached to the partition 22, and the first valve plate 251 rotates to the opening of the first chamber 23 and seals the opening of the first chamber 23.
It can be understood that, in order to make each valve plate rotate in each chamber, a movable gap is arranged between the valve plate and the side plate, in order to ensure the sealing effect between the valve plate and each opening, each opening can be provided with a sealing flange, when the valve plate rotates to the opening position, the sealing flange can be abutted against the valve plate, and then the influence of the gap between each valve plate and the side plate on the sealing effect is eliminated.
The first valve plate 251 can completely seal the opening of the first chamber 23 in the present embodiment, and the second valve plate 252 can also completely seal the opening of the second chamber 24; in other embodiments, the first valve plate 251 can completely seal the opening of the first chamber 23, and the second valve plate 252 can be provided with vent holes, so that the air conditioner can be in a fresh air mode, and can mix partial indoor air to adjust the temperature of fresh air. For example, in winter, the temperature of outdoor fresh air is lower, the temperature of indoor wind is higher, the air conditioner is in the fresh air mode, and the introduced outdoor fresh air can mix partial indoor wind to raise the temperature of the mixed fresh air and improve the comfort level of the air conditioner.
Referring to fig. 6, a washing structure 30 according to an embodiment of the present invention includes a water tank 31 and a washing assembly 32 disposed in the water tank 31; wherein, the water tank 31 is provided with a water tank air inlet 312 communicated with the opening of the air inlet structure 20, so that the air passing through the air inlet structure 20 flows into the water tank 31, and the water washing component 32 performs the water washing treatment on the air. For example, the water washing assembly 32 is used for washing the air entering the water tank 31 with water, so that dust, bacteria, viruses and the like in the air are dissolved in the water or removed by water molecules and negative ions formed by the water washing assembly 32, thereby completing the water washing purification of the air.
