Meanwhile, the driving device 152 drives the steam nozzle 150 to move, so that the steam nozzle 150 can spray steam towards different parts or different directions, thereby realizing uniform humidification of air in the indoor unit and further improving the experience comfort level of users.
The movable mounting of the steam nozzle 150 will be described in detail below, specifically as follows:
referring to fig. 5 and 6, in an embodiment, the steam nozzle 150 is slidably installed in the air duct back and forth; and/or, the steam nozzle 150 is slidably installed in the air duct up and down.
In this embodiment, the housing 110 is provided with a sliding groove extending in an up-down direction, and an end portion of the steam nozzle 150 is installed in the sliding groove such that the steam nozzle 150 can slide up and down along the sliding groove. Alternatively, the housing 110 is provided with a sliding groove extending in the front-rear direction. There are various ways for the driving means 152 to drive the steam nozzle 150 to slide, for example, a chain transmission manner or a rack and pinion transmission manner.
In another embodiment, the steam nozzle 150 is installed in the wind tunnel to swing back and forth; and/or the steam nozzle 150 is installed in the air duct in a manner of swinging up and down.
In this embodiment, the driving device 152 is a driving motor, and the driving motor drives the steam nozzle 150 to swing through an eccentric wheel. Specifically, one end of the steam nozzle 150 is hinged to the housing 110, and the other end of the steam nozzle 150 is connected to the driving motor through the eccentric wheel, so that the steam nozzle 150 can swing up and down or back and forth with the hinge point as a pivot. It should be noted that the hinge point may also be located at the middle of the steam nozzle 150, that is, the middle of the steam nozzle 150 is hinged to the housing 110. In addition, in this embodiment, the driving motor may also drive the steam nozzle 150 to swing through the link assembly. Here, the manner in which the driving device 152 drives the steam nozzle 150 to swing is not particularly limited.
Referring to fig. 7 and 8, in another embodiment, the steam nozzle 150 is rotatably installed in the wind tunnel along its axis. Specifically, referring to fig. 9, the driving device 152 is a driving motor, and the driving motor is connected to one end of the steam nozzle 150 to drive the steam nozzle 150 to rotate around its axis.
In this embodiment, considering that the steam nozzle 150 receives a reaction force in a direction opposite to the air injection direction when the steam nozzle 150 injects air, in order to prevent the steam nozzle 150 from moving in the direction opposite to the air injection direction, a bracket may be further provided in the housing 110, the bracket being provided with a mounting groove in which the steam nozzle 150 is rotatably mounted. Specifically, the mounting groove is a U-shaped groove with an upward opening.
Referring to fig. 2 to 4, in the above embodiments, the steam nozzle 150 may be installed at various positions in the air duct.
For example, the steam nozzle 150 is movably installed between the air inlet 111 and the wind wheel 120 (as shown in fig. 2). Thus, the steam nozzle 150 can spray steam toward different positions, and the steam is blown to the wind wheel 120 and the heat exchanger 130 in sequence by the indoor return air entering the air duct from the air inlet 111 and then blown out from the air outlet 112, so as to humidify the indoor air.
Alternatively, the steam nozzle 150 is movably installed between the heat exchanger 130 and the air outlet 112 (as shown in fig. 3). Specifically, the air outlet 112 is provided with an air guide louver 140, and the steam nozzle 150 is movably installed between the heat exchanger 130 and the air guide louver 140. Therefore, indoor return air enters the air duct from the air inlet 111, sequentially passes through the wind wheel 120 and the heat exchanger 130, and finally blows the steam sprayed by the steam spray pipe 150 into the room to humidify the indoor air.
Still alternatively, the steam nozzle 150 is movably installed between the wind wheel 120 and the heat exchanger 130 (as shown in fig. 4). Specifically, referring to fig. 7 and 8, the heat exchanger 130 includes an upper heat exchanging portion 131 and a lower heat exchanging portion 132 arranged in a crossing manner. When the steam nozzle 150 moves upward (slides, swings, or rotates), the steam nozzle 150 may spray steam to the upper heat exchanging part 131; when the steam nozzle 150 is moved downward (slid, swung, or rotated), the steam nozzle 150 may spray steam to the lower heat exchange portion 132. Therefore, indoor return air enters the air duct from the air inlet 111, passes through the wind wheel 120, and then uniformly brings the steam sprayed from the steam spray pipe 150 into the heat exchanger 130, and then blows the steam out of the air outlet 112, so as to humidify the indoor air.
It is worth mentioning that the plurality of the air injection holes 151 are located on the leeward side of the steam injection pipe 150 in order to better realize the injection of the steam injected from the steam injection pipe 150 into the room and the humidification of the air in the room. 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.
In addition, in the above embodiments, there are various arrangements of the plurality of gas injection holes 151 on the steam nozzle 150, and no special limitation is made here. Referring to fig. 10 and 11, a plurality of the gas injection holes 151 are arranged at intervals along the axial direction of the steam nozzle 150. In the axial direction of the steam nozzle 150, the distance between two adjacent gas injection holes 151 is uniform, and of course, the distance between two adjacent gas injection holes 151 may not be uniform.
Further, at least two rows of the gas injection holes 151 are axially formed on the steam nozzle 150. In order to allow the steam nozzle 150 to spray air in different directions, and to achieve uniform humidification, optionally, a plurality of rows of the air spraying holes 151 are formed in the axial direction of the steam nozzle 150. In one embodiment, referring to fig. 10, a plurality of rows of the gas injection holes 151 are arranged in an array; of course, it is understood that in another embodiment, referring to fig. 11, two adjacent rows of the gas injection holes 151 may be alternatively arranged in the circumferential direction of the steam nozzle 150.
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 150a and a second end 150b disposed opposite each other, the first end 150a being provided with an air inlet such that steam inside the steam nozzle 150 flows from the first end 150a to the second end 150 b. Here, the air inlet may be opened at an end surface of the first end 150a of the steam nozzle 150, or may be opened at a sidewall of the first end 150a 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 first end 150a toward the second end 150 b. 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 to the above embodiments, the diameter of the gas injection hole 151 is 1mm to 10 mm. On one hand, the diameter of the air injection hole 151 is too small, which causes a small amount of injected steam and makes it difficult to fully humidify the indoor air; on the other hand, the diameter of the air injection hole 151 is too large, which causes the injection distance to be reduced, so that the air injected through the steam injection pipe 150 falls downward and is not easy to be blown into the room by the indoor return air in the air duct. Therefore, the gas injection holes 151 may alternatively have a diameter of 1mm to 10 mm. Here, it should be noted that the shape of the gas injection holes 151 may be circular, square, triangular, or other shapes, wherein the diameter of the gas injection holes 151 refers to the equivalent diameter of the gas injection holes 151. For ease of molding, the gas injection holes 151 are preferably circular holes.
The utility model also provides an air conditioner, this air conditioner include machine 100 in air condensing units and at least one suspension type air conditioner, and the concrete structure of this air conditioner refers to above-mentioned embodiment, because this suspension type air conditioner indoor set 100 has adopted the whole technical scheme of above-mentioned all embodiments, consequently has all beneficial effects that the technical scheme of above-mentioned embodiment brought at least, and the repeated description is no longer given here.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
