Here, the air blowing unit 200 shown in fig. 7 is a view in which the air blowing unit 200 shown in fig. 5 is turned over by a certain angle with its longitudinal direction as an axis.
As shown in fig. 2 to 9, the present embodiment first provides a wall-mounted fresh air conditioner indoor unit 011, which generally includes: a casing 10, a fresh air device 100 and an air supply part 200.
The fresh air device 100 is disposed at one lateral end of the casing 10, and a first fresh air outlet 110 is formed at the bottom thereof. The air supply part 200 is connected to the first fresh air outlet 110, and is formed by extending from the first fresh air outlet 110 along the transverse direction of the cabinet 10, and an air outlet 210 is provided at the front side of the air supply part 200, so that fresh air is supplied to the outside of the cabinet 10 through the air outlet 210. An air duct 220 is formed inside the air supply part 200, and the cross section of the air duct 220 gradually decreases from one end near the first fresh air outlet 110 to the other end.
In the scheme of this embodiment, the air supply part 200 connected to the first fresh air outlet 110 is arranged to extend along the transverse direction of the housing 10, and the air outlet 210 is arranged at the front side of the air supply part 200, so that the air outlet range of the fresh air is increased.
In some preferred embodiments, the air outlet 210 may be a strip-shaped opening integrally disposed along the transverse direction of the casing 10, which not only increases the air outlet range of the fresh air, but also improves the air outlet uniformity of the fresh air.
The fresh air flows through the first fresh air outlet 110, enters the air supply duct 220 of the air supply unit 200, and then flows to the outside of the air supply unit 200 through the air outlet 210 at the front side of the air supply duct 220.
The new trend can flow towards the direction of keeping away from first fresh air outlet 110 under the effect of fan (the fan is located inside new trend device 100, not shown in the figure) to make the new trend flow out from the place of keeping away from first fresh air outlet 110 mostly, and then lead to the new trend air-out inhomogeneous.
In order to solve the above technical problem, in the embodiment, an air supply duct 220 is formed inside the air supply part 200, and the cross section of the air supply duct 220 is gradually reduced from one end close to the first fresh air outlet 110 to the other end, so that the wind resistance of the air supply duct 220 is increased along with the increase of the distance from the first fresh air outlet 110. The resistance that makes the new trend receive at a distance from first new trend air outlet 110 is big more to make the new trend can follow the place that the distance from first new trend air outlet 110 is close and flow out, and then improved the homogeneity that the new trend flowed out from air supply unit 200.
