Referring to fig. 1 to 5, a ceiling type air conditioner indoor unit 100 according to the present invention includes a casing 110 and a main air nozzle. The housing 110 is provided with an air inlet 111, an air outlet 112, and an air duct communicating the air inlet 111 with the air outlet 112. The steam nozzle 150 is disposed in the air duct, a plurality of air injection holes 151 are disposed on the steam nozzle 150, the steam nozzle 150 includes a first end 150a and a second end 150b which are disposed oppositely, the first end 150a of the steam nozzle 150 is provided with an air inlet, and the distribution density of the air injection holes 151 gradually increases from the first end 150a to the second end 150 b.

In the embodiment of the present invention, the housing 110 includes a front panel and a back panel which are oppositely disposed, and a top plate and a bottom plate which connect the front panel and the back panel. The air inlet 111 is disposed on the bottom plate, and the air outlet 112 is disposed on the front panel. Therefore, indoor return air enters the air channel from the air inlet 111, and steam sprayed out of the steam spray pipe 150 is blown into the room, so that the indoor air is humidified. The ceiling type indoor unit 100 of an air conditioner further includes a wind wheel 120 and a heat exchanger 130, and both the wind wheel 120 and the heat exchanger 130 are disposed in the air duct. The wind wheel 120 is used for driving indoor return air to enter the air duct from the air inlet 111, and the return air flows back to the indoor through the air outlet 112 after passing through the heat exchanger 130 for heat exchange. In order to increase the heat exchange efficiency of the heat exchanger 130, the heat exchanger 130 is provided in a multi-fold shape, for example, two-fold or three-fold, and of course, the heat exchanger 130 may also be provided in a flat plate shape.

The steam nozzle 150 may be disposed at various positions in the air duct, for example, the steam nozzle 150 may be disposed at the air inlet 111, the air outlet 112, or the middle of the air duct. It is not particularly limited thereto and will be described in detail hereinafter. The steam nozzle 150 is formed in a tubular shape and has a cavity formed therein. The steam spray pipe 150 may be fixed to the housing 110, and particularly, an end of the steam spray pipe 150 may be fixed to a side plate of the housing 110. Of course, the steam nozzle 150 may be fixed to the bracket, wherein the bracket is disposed in the housing 110. In addition, there may be a plurality of extending directions of the steam nozzle 150, for example, the steam nozzle 150 extends along the length direction of the wind wheel 120, or the steam nozzle 150 extends along the length direction perpendicular to the wind wheel 120, or the extending direction of the steam nozzle 150 forms an included angle with the length direction of the wind wheel 120, which is not limited herein. The steam nozzle 150 extends along the length of the wind wheel 120 as an example.

The steam nozzle 150 includes first and second opposing ends 150a, 150b, and the first end 150a of the steam nozzle 150 is provided with an inlet for steam to enter the steam nozzle 150. Thus, within the steam nozzle 150, steam 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 order to achieve uniform gas injection throughout the steam nozzle 150, the distribution density of the gas injection holes 151 of the steam nozzle 150 may be gradually increased along the direction from the first end 150a to the second end 150 b. In this way, the amount of steam ejected from each portion of the steam ejection holes 150 is substantially equal, so that uniform humidification can be achieved.

In an embodiment of the present invention, the ceiling type air conditioner indoor unit 100 further includes a steam generating device 160, and the steam generating device 160 is connected to the steam nozzle 150 to provide steam to the steam nozzle 150. Specifically, the steam generating device 160 includes a water tank 161 and a heating device 164, the water tank 161 is disposed in a sealed manner, and the heating device 164 is disposed in the water tank 161 for heating water in the water tank 161. The water tank 161 is provided with a water inlet pipe 162, and the water inlet pipe 162 is used for supplying water to the inside of the water tank 161; the water tank 161 is further provided with a steam delivery pipe 163, and the steam delivery pipe 163 is connected to the steam nozzle 150 to deliver steam to the steam nozzle 150. The steam generator 160 may be provided inside the casing 110 of the ceiling-mounted indoor unit, or may be provided outside the casing 110.

The technical scheme of the utility model through set up steam spray tube 150 in the wind channel of indoor set 100 of ceiling type air conditioner, a plurality of fumaroles 151 have been seted up on this steam spray tube 150, so, vapor in this steam spray tube 150 spouts to the wind channel in through fumarole 151, then blows in indoorly through indoor circulation return air again, in order to carry out the humidification to the room air, thereby when the air conditioner heats, when the room air temperature rose, the relative humidity of room air also can increase, user's experience comfort level has been improved. Meanwhile, in the steam flowing direction, the distribution density of the fumaroles 151 on the steam nozzle 150 is gradually increased, so that the distribution density of the fumaroles 151 located at the rear of the steam flowing direction is greater than the distribution density of the fumaroles 151 located at the front of the steam flowing direction, even if the steam pressure located at the rear of the steam flowing direction is reduced, uniform air injection of all parts of the whole steam nozzle 150 can still be realized, uniform humidification can be realized, and the experience comfort level of a user is further improved.

There are various distributions of the plurality of gas injection holes 151 in the steam nozzle 150. For example, referring to fig. 5, in an embodiment, the plurality of gas injection holes 151 are randomly distributed, and the distribution density of the gas injection holes 151 gradually increases along a direction from the first end 150a to the second end 150 b. That is, in the steam flow direction, the total number of the air injection holes 151 in the front in the flow direction is small, and the total number of the air injection holes 151 in the rear in the flow direction is large. This ensures that the steam sprayed from each part of the entire steam nozzle 150 is very uniform, and uniform humidification is achieved.

Referring to fig. 6, in another embodiment, a plurality of the gas injection holes 151 are arranged at intervals along the axial direction of the steam nozzle 150. Specifically, the steam nozzle 150 is provided with at least one row of gas injection holes 151, and the distance d between two adjacent gas injection holes 151 in the axial direction of the steam nozzle 150 gradually decreases along the direction from the first end 150a to the second end 150 b. That is, in the flow direction of the steam, the distance d between two adjacent gas injection holes 151 in the front in the flow direction is larger (the distribution density of the gas injection holes 151 is larger), and the distance d between two adjacent gas injection holes 151 in the rear in the flow direction is smaller (the distribution density of the gas injection holes 151 is smaller). In this manner, even if the pressure of the steam within the steam nozzle 150 is gradually reduced in the flowing direction of the steam through the steam nozzle 150, the steam can be uniformly sprayed through all parts of the steam nozzle 150.

Further, in the axial direction of the steam nozzle 150, the distance d between two adjacent gas injection holes 151 is 5mm to 300 mm. This is because if the distance d between two adjacent air injection holes 151 is too small, it is not favorable to achieve uniform air injection through the steam injection pipe 150; if the distance d between two adjacent gas injection holes 151 is too large, the amount of gas injection through the steam nozzle 150 is reduced, thereby reducing the humidification efficiency. Preferably, the distance d between two adjacent gas injection holes 151 in the axial direction of the steam injection pipe is 100mm to 200 mm. In this embodiment, the plurality of gas injection holes 151 have a uniform diameter, that is, the plurality of gas injection holes 151 have substantially the same diameter. Thus, the amount of steam ejected from each of the gas ejection holes 151 is also substantially equal. In addition, for convenience of description, the gas injection holes 151 arranged in sequence in the steam flow direction of the steam nozzle 150 may be defined as a first gas injection hole, a second gas injection hole and a third gas injection hole, the distance between the first gas injection hole and the second gas injection hole is d1, the distance between the second gas injection hole and the second gas injection hole is d2, wherein δ d1 is d1-d2, and δ d2 is d2-d 3. In this embodiment, δ d1 may be equal to δ d2, although δ d1 and δ d2 may be random.

The mounting location of the steam nozzle 150 will be described in detail below, specifically as follows:

referring to fig. 2, in an embodiment, the steam nozzle 150 is located between the air inlet 111 and the wind wheel 120; thus, the steam sprayed from the steam nozzle 150 is firstly sucked by the wind wheel 120, then sequentially passes through the heat exchanger 130 and the air outlet 112, and finally flows into the room to humidify the indoor air.

Referring to fig. 3, in another embodiment, the steam nozzle 150 is located between the heat exchanger 130 and the air outlet 112; 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.

Referring to fig. 4, in another embodiment, the steam nozzle 150 is located between the wind wheel 120 and the heat exchanger 130; therefore, indoor return air enters the air duct from the air inlet 111, passes through the wind wheel 120, brings the steam sprayed by the steam spray pipe 150 into the heat exchanger 130, and 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.

There are various shapes of the gas injection holes 151, for example, a circular shape, a triangular shape, a square shape, or other shapes. For ease of molding, the gas injection holes 151 are preferably circular holes. Taking a circular hole as an example, the diameter of the air 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.

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.

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.
