Referring to fig. 5, the cross section of the steam nozzle 150 is circular, and the diameter of the circular cross section along the horizontal direction is used as a boundary, so that the upper portion of the pipe wall of the steam nozzle 150 above the boundary is defined as the upper portion, and the lower portion of the pipe wall of the steam nozzle 150 below the boundary is defined as the lower portion.
In this embodiment, the steam nozzle 150 is located between the wind wheel 120 and the heat exchanger 130. Specifically, the heat exchanger 130 includes an upper heat exchange portion 131 and a lower heat exchange portion 132 which are arranged at an included angle, the openings of the first type of gas injection holes 151a face the upper heat exchange portion 131, and the openings of the second type of gas injection holes 151b face the lower heat exchange portion 132. That is, the first type gas injection holes 151a may inject gas toward the upper heat exchange portion 131, and the second type gas injection holes 151b may inject gas toward the lower heat exchange portion 132. Therefore, on one hand, the steam jet pipe 150 can jet air in different directions, so that the air of the indoor unit can be uniformly humidified; on the other hand, the surface of the heat exchanger 130 can be cleaned to remove the dirt attached to the surface of the heat exchanger 130.
Further, referring to fig. 6 and 7, the axis of the steam nozzle 150 has a first projection point P on a projection plane perpendicular to the steam nozzle 150, the center of the first type of gas injection holes 151a has a second projection point M on the projection plane, and a connecting line between the first projection point P and the second projection point M and a projection of the windward side of the upper heat exchange portion 131 on the projection plane form an included angle θ, wherein θ is greater than or equal to 30 ° and less than or equal to 90 °. Here, it should be noted that a connecting line between the first projection point P and the second projection point M is used to indicate the jetting direction of the first type gas injection holes 151 a. That is, the included angle between the spraying direction of the first type of air spraying holes 151a and the windward side of the upper heat exchanging part 131 is θ, wherein θ is greater than or equal to 30 ° and less than or equal to 90 °. When θ is 90 °, the first-type air injection holes 151a inject air perpendicularly toward the windward side of the upper heat exchange portion 131.
Similarly, the center of the second type of air injection hole 151b has a third projection point on the projection plane, and an included angle between a connecting line between the first projection point P and the third projection point and the projection of the windward side of the lower heat exchange portion 132 on the projection plane is β, wherein β is greater than or equal to 30 ° and less than or equal to 90 °. Here, it should be noted that a connecting line between the first projection point P and the third projection point N is used to indicate the ejection direction of the second type gas injection holes 151 b.
Referring to fig. 8 and 9, in another embodiment, the gas injection holes 151 further include a third type of gas injection holes 151c, and the third type of gas injection holes 151c are located between the first type of gas injection holes 151a and the second type of gas injection holes 151 b.

This is because it is considered that if the air injection holes 151 are provided on the windward side of the steam nozzle 150, when the indoor return air in the wind tunnel is blown toward the steam nozzle 150, the indoor return air is likely to enter the steam nozzle 150 from the air injection holes 151, thereby causing the steam nozzle 150 not to inject air normally.
The plurality of air injection holes 151 are arranged in the axial direction of the steam nozzle 150 at intervals, wherein at least two rows of the air injection holes 151 are arranged in the axial direction of the steam nozzle 150. In order to make the steam nozzle 150 inject the air in different directions to achieve uniform humidification, optionally, a plurality of rows of the air injection holes 151 are formed in the axial direction of the steam nozzle 150 (as shown in fig. 8). In one embodiment, the plurality of rows of the gas injection holes 151 are arranged in an array. Of course, in other embodiments, two adjacent rows of the gas injection holes 151 may be staggered in the circumferential direction of the steam nozzle 150 (as shown in fig. 9).
It is understood that the steam nozzle 150 has an inlet for steam, and the inlet of the steam nozzle 150 is disposed at an end or a middle portion of the steam nozzle 150. To facilitate the input of steam into the steam nozzle 150, the air inlet may be provided at an end of the steam nozzle 150. Specifically, the steam nozzle 150 includes a first end and a second end disposed opposite to each other, the first end being provided with an air inlet such that steam inside the steam nozzle 150 flows from the first end to the second end. Here, the air inlet may be opened at an end surface of the first end of the steam nozzle 150, or may be opened at a side wall of the first end of the steam nozzle 150.
It is contemplated that the steam pressure within the steam nozzle 150 may gradually decrease in the direction of flow of steam through the steam nozzle 150, thereby resulting in non-uniform steam throughout the steam nozzle 150. Therefore, in a preferred embodiment, in order to achieve uniform gas injection throughout the steam nozzle 150, the diameter of the gas injection holes 151 may be gradually increased along the direction from the first end toward the second end. In this embodiment, the distance between any two adjacent gas injection holes 151 is consistent in the axial direction of the steam nozzle 150, that is, the distance between any two adjacent gas injection holes 151 is approximately equal. Of course, it is understood that the distance between any two adjacent gas injection holes 151 may be different in the axial direction of the steam nozzle 150, and is not limited herein.
In addition, in the embodiments, the gas injection holes 151 are provided with nozzles, and when steam enters from the gas inlet of the steam nozzle 150 and is injected from the gas injection holes 151, the nozzles can rotate around the center line of the corresponding gas injection holes 151 under the driving of the gas flow. Thus, in the rotating process of the nozzle, air can be sprayed towards all directions, and uniform humidification can be better realized.
