Detailed Embodiments

[0026] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments and features in the present application can be combined with each other arbitrarily.

[0027] Analysis and research found that during the operation of the air blower, the air beam blown from the first cavity to the windward area through the communication port, a part of it blows towards the heat exchanger in the windward area, and the other part blows towards the first area in the windward area. Among them, the air beam blowing towards the first area will form a turbulent flow in the first area to generate a swirling sound, and the swirling sound will be transmitted to the windward area and blown out of the air duct machine along with the air beam blowing towards the heat exchanger.

[0028] The air duct machine provided by the embodiment of the present utility model, as Figures 1 to 5 shown, includes: a housing 100, the interior of the housing 100 is separated into a first cavity 110 and a second cavity 120 by a partition wall 200. The first cavity 110 and the second cavity 120 are arranged in sequence in the first horizontal direction (such as the front-back direction). The second cavity 120 includes a first area 121 and a second area 122. The first area 121 and the second area 122 are arranged in sequence in the second horizontal direction (such as the left-right direction). The partition wall 200 is provided with a communication port 210, and the first horizontal direction and the second horizontal direction intersect; a heat exchanger 300, the heat exchanger 300 is arranged in the second area 122, and an air-facing area is formed between the heat exchanger 300, the partition wall 200 and the bottom wall 130 of the housing 100. The communication port 210 communicates the first cavity 110 and the air-facing area; and a first wind blocking member 400, the first wind blocking member 400 is located between the air-facing area and the first area 121, and is arranged to separate the air-facing area and the first area 121.

[0029] In this air duct machine, the first wind blocking member 400 is located between the air-facing area and the first area 121 and is used to separate the air-facing area and the first area 121. In this way, the air beam blown from the first cavity 110 to the air-facing area through the communication port 210 is basically all blown towards the heat exchanger 300 in the air-facing area, and basically will not be blown towards the first area 121 in the air-facing area. Therefore, basically no turbulent flow will be generated in the first area 121 to generate a swirling sound, so there is basically no swirling sound in the air beam blown out of the air duct machine.

[0030] Among them, as Figure 2As shown, the air duct machine further includes: a throttling component 500, which is disposed in the first region 121 and is connected to the heat exchanger 300. Furthermore, on one side of the heat exchanger 300 in the second region 122 that is opposite to the windward region, an air outlet region is formed (i.e., the air outlet region is located on the side of the windward region that is opposite to the communication port 210). The air duct machine further includes: a second wind baffle 600, which is disposed between the air outlet region and the first region 121 and is configured to separate the air outlet region and the first region 121. In this solution, the first region 121 is basically set as a closed region. During the operation of the air duct machine, the sound generated by the throttling component 500 (as well as other sounds in the first region 121) is restricted within the first region 121 and cannot spread out, and will not enter the windward region and the air outlet region and be blown out of the air duct machine along with the air beam. In this way, the noise transmitted during the operation of the air duct machine is smaller. It is possible that the throttling component 500 is set as an electronic expansion valve (or capillary tube, etc.), and the sound generated by the electronic expansion valve during the operation of the air duct machine is the start-stop sound of the electronic expansion valve.

[0031] In some examples, as Figures 3 to 5 shown, the first wind baffle 400 is provided with a clamping portion 410, and the partition wall 200 is provided with a clamping cooperation portion 220. The clamping portion 410 is clamped with the clamping cooperation portion 220 to assemble the first wind baffle 400 and the partition wall 200 together. Compared with screw connection, the operation of clamping connection is simpler and the assembly efficiency is higher.

[0032] In some examples, as Figure 3 and Figure 4 shown, the first wind baffle 400 is further provided with a guiding portion 420, and the partition wall 200 is further provided with a guiding cooperation portion 230. The guiding portion 420 is matched with the guiding cooperation portion 230 and is configured to guide the clamping portion 410 to be clamped with the clamping cooperation portion 220, so that the assembly speed of the clamping portion 410 and the clamping cooperation portion 220 can be effectively improved.

[0033] It is possible that, as Figure 4 shown, the clamping portion 410 is located on the side of the guiding portion 420 close to the bottom wall 130 of the housing 100, and the clamping cooperation portion 220 is located on the side of the guiding cooperation portion 230 close to the bottom wall 130 of the housing 100; or it is possible that the clamping portion 410 is located on the side of the guiding portion 420 away from the bottom wall 130 of the housing 100, and the clamping cooperation portion 220 is located on the side of the guiding cooperation portion 230 away from the bottom wall 130 of the housing 100, etc. The above can all achieve the purpose of the present application, and its gist does not deviate from the design concept of the present utility model, so it will not be elaborated here and all should fall within the protection scope of the present application.

[0034] It is possible that the guiding portion 420 is arranged as a guiding post, and the guiding mating portion 230 is arranged as a guiding groove. At this time, the width of the guiding groove is set to gradually decrease from top to bottom. In this way, during the process of installing the first wind shield 400 along the side surface of the partition wall 200 towards the bottom wall 130 of the housing 100, when the first wind shield 400 is initially installed, it is easier for the guiding post to insert into the upper part of the guiding groove, and after the first wind shield 400 is installed in place, the positioning effect of the guiding post in the lower part of the guiding groove is also better; or it is possible that, as Figure 4 shown, the guiding portion 420 is arranged as a guiding groove, and the guiding mating portion 230 is arranged as a guiding post. At this time, the width of the guiding groove is set to gradually increase from top to bottom. In this way, during the process of installing the first wind shield 400 along the side surface of the partition wall 200 towards the bottom wall 130 of the housing 100, when the first wind shield 400 is initially installed, it is easier for the lower part of the guiding groove to be sleeved on the guiding post, and after the first wind shield 400 is installed in place, the positioning effect of the upper part of the guiding groove on the guiding post is also better; the above can all achieve the purpose of the present application, and its gist does not deviate from the design concept of the present utility model, so it will not be elaborated here and all should fall within the protection scope of the present application.

[0035] Certainly, it is also possible that the width of the guiding groove remains unchanged from bottom to top or other changing manners, etc., which can all achieve the purpose of the present application, and its gist does not deviate from the design concept of the present utility model, so it will not be elaborated here and all should fall within the protection scope of the present application.

[0036] It is possible that the clamping portion 410 is arranged as a buckle, and the clamping mating portion 220 is arranged as a clamping groove. In this way, during the process of installing the first wind shield 400 along the side surface of the partition wall 200 towards the bottom wall 130 of the housing 100, the buckle is clamped downward into the clamping groove; or it is possible that the clamping portion 410 is arranged as a clamping groove, and the clamping mating portion 220 is arranged as a buckle. In this way, during the process of installing the first wind shield 400 along the side surface of the partition wall 200 towards the bottom wall 130 of the housing 100, the clamping groove is sleeved downward on the buckle; the above can all achieve the purpose of the present application, and its gist does not deviate from the design concept of the present utility model, so it will not be elaborated here and all should fall within the protection scope of the present application.

[0037] In an embodiment, as Figure 3 and Figure 4As shown, the clamping portion 410 is located on one side of the guiding portion 420 close to the bottom wall 130 of the housing 100. The clamping and mating portion 220 is located on one side of the guiding and mating portion 230 close to the bottom wall 130 of the housing 100. A clamping groove is convexly provided at a position on the side of the partition wall 200 facing the second cavity 120 and close to the bottom wall 130 of the housing 100. The notch of the clamping groove faces away from the bottom wall 130 of the housing 100. A notch 430 is provided at a position on one end of the first wind shield 400 facing the partition wall 200 and close to the bottom wall 130 of the housing 100. Both the side of the notch 430 facing the partition wall 200 and the side of the notch 430 facing the bottom wall 130 of the housing 100 are through. A clamping buckle is convexly provided on the mouth wall of the notch 430 opposite to the bottom wall 130 of the housing 100. The clamping buckle extends towards the side where the bottom wall 130 of the housing 100 is located. After the first wind shield 400 is installed in place, the clamping buckle is snapped into the clamping groove. At this time, one end of the first wind shield 400 facing the bottom wall 130 of the housing 100 is hermetically abutted against the bottom wall 130 of the housing 100. One end of the first wind shield 400 facing the heat exchanger 300 is hermetically abutted against the side plate of the heat exchanger 300 (close to the first region 121). One end of the first wind shield 400 facing the partition wall 200 is hermetically abutted against the partition wall 200.

[0038] In one embodiment, as Figure 4 and Figure 5 shown, a sealing edge 460 is further convexly provided at one end of the side of the first wind shield 400 close to the partition wall 200. The sealing edge 460 abuts against the side of the partition wall 200 and is fixedly connected to the partition wall 200 by screws.

[0039] In some embodiments, as Figure 4 and Figure 5 shown, the first wind shield 400 is provided as a wind shield plate. Sealing sponges 440 and anti-condensation sponges 450 are provided at the edge of the wind shield plate. The sealing sponges 440 are used to seal the gap between the wind shield plate and the side plate of the heat exchanger 300 to avoid air leakage at this place.

[0040] In some embodiments, as Figure 1 and Figure 2As shown in the figure, the air duct machine further includes: a fan 700 disposed in the first cavity 110. The air outlet of the fan 700 is communicated with the windward area through the communication port 210. The air inlet of the fan 700 is located in the first cavity 110. The fan 700 is arranged to form an air beam that blows from the first cavity 110 through the communication port 210 and the windward area to the heat exchanger 300 in sequence; and a water receiving tray 800 disposed in the second cavity 120 and on one side of the heat exchanger 300 away from the bottom wall 130 of the housing 100. After the air duct machine is installed on the ceiling, the bottom wall 130 of the housing 100 is located at the upper part. The upper end of the heat exchanger 300 is far from the upper end of the partition wall 200, the lower end of the heat exchanger 300 is close to the lower end of the partition wall 200, the water receiving tray 800 is located below the heat exchanger 300 (i.e., the water receiving tray 800 is located at the lower part of the housing 100), and the first wind blocking member 400 is in a triangular shape.

[0041] Of course, it can also be that after the air duct machine is installed on the ceiling, the bottom wall 130 of the housing 100 is located at the lower part (not shown in this embodiment in the figure). The upper end of the heat exchanger 300 is close to the upper end of the partition wall 200, the lower end of the heat exchanger 300 is far from the lower end of the partition wall 200, the water receiving tray is disposed between the bottom wall 130 of the housing 100 and the heat exchanger 300, and a windward area is formed among the water receiving tray 800, the heat exchanger 300 and the partition wall 200. The first wind blocking member 400 is in a triangular shape, which can also achieve the purpose of the present application. Its gist does not depart from the design concept of the present invention, so it will not be elaborated here and should also be within the protection scope of the present application.

[0042] In some embodiments, the second wind blocking member 600 is set as a partition board, and a sealing sponge for sealing the gap is provided at the edge of the partition board.

[0043] The air conditioner (not shown in the figure) provided by the embodiment of the present invention includes the air duct machine described in any of the above embodiments.

[0044] This air conditioner has all the advantages of the air duct machine provided in any of the above embodiments, so it will not be elaborated here.

[0045] In summary, for the air duct machine provided by the embodiment of the present invention, the first wind blocking member is located between the windward area and the first area and is used to separate the windward area and the first area. In this way, the air beam blowing from the first cavity through the communication port into the windward area basically blows towards the heat exchanger within the windward area and basically does not blow towards the first area within the windward area. Therefore, basically no turbulent flow is generated in the first area to produce a swirling sound, so the air beam blown out by the air duct machine basically has no swirling sound.
