[0033] Compared with traditional vertical or hanging air conditioners, mobile air conditioners are smaller in size, more portable and require no installation, and are being chosen by more and more users. In the related art, mobile air conditioners are equipped with a double-headed motor and a fan wheel to deliver air to the condensation area and evaporation area of ​​the air conditioner. However, the shell structure of such mobile air conditioners easily causes air flow backflow in the air conditioner, affecting the air supply effect.

[0034] In view of the technical problems existing in the prior art, the utility model proposes an air-conditioning shell structure, which improves the air inlet structure of the volute used for the mobile air-conditioning, effectively reduces the backflow of the mobile air-conditioning airflow, and enhances the air supply effect.

[0035] Reference Figure 1 and Figure 2 The air conditioner housing structure provided by the embodiment of the first aspect of the utility model includes an outer shell and a volute assembly. The outer shell includes a surrounding shell 100, an upper cover 110 and a bottom shell 120 for covering the surroundings. The upper cover 110 is arranged above the surrounding shell 100 and closes the upper end of the surrounding shell 100. The bottom shell 120 is arranged below the surrounding shell 100 and closes the lower end of the surrounding shell 100. The surrounding shell 100 is connected with the upper cover 110 and the bottom shell 120 through a detachable structure such as a buckle, and then partially fixed with screws. The volute assembly is arranged in the accommodating cavity of the outer shell and is used to install a double-headed motor 400, and the air supply in the shell is realized by the double-headed motor 400.

[0036] Reference Figures 1 to 3The volute assembly includes a first volute 200 and a second volute 300. The housing cavity of the housing is divided by the first volute 200 to form a first heat exchange area 130 and a second heat exchange area 140. Figure 3 As shown, the first heat exchanger is located at the bottom and the second heat exchange area 140 is located at the top. The first heat exchange area 130 is used to install the condensing assembly, and the second heat exchange area 140 is used to install the evaporator assembly 600. The second volute 300 is located in the second heat exchange area 140, and the second volute 300 is installed on the first volute 200 and is located above the first volute 200, so that it is convenient to disassemble the volute assembly. In other embodiments, the second volute 300 can also be installed on the outer shell. The two ends of the double-headed motor 400 are respectively provided with a first wind wheel 410 and a second wind wheel 420, and the double-headed motor 400 is installed on the first volute 200. The first wind wheel 410 is located in the first volute 200, and the second wind wheel 420 is located in the second volute 300. The air supply of the first heat exchange area 130 and the second heat exchange area 140 inside the air-conditioning housing can be achieved by a fan.

[0037] It should be noted that the housing is provided with two sets of air supply structures, one set of air supply structures is used for the air inlet and air outlet of the first heat exchange area 130 in the accommodating cavity, and the other set of air supply structures is used for the air inlet and air outlet of the second heat exchange area 140 in the accommodating cavity. The air supply structure is provided with an air inlet portion and an air outlet portion.

[0038] It is understandable that if Figure 3 As shown, for the air supply structure of the first heat exchange zone 130, external air enters from the first air inlet driven by the double-headed motor 400 and the first wind wheel 410, enters from the air inlet of the first volute 200 after passing through the condenser, enters into the air supply cavity of the first volute 200 after passing through the first wind wheel 410, and then flows out from the first air outlet. The first air outlet used for the first heat exchange zone 130 is generally connected to an external air supply duct to deliver the hot air that has undergone heat exchange in the condenser to the outdoors; for the air supply structure of the second heat exchange zone 140, external air enters from the second air inlet driven by the double-headed motor 400 and the second wind wheel 420, enters from the air inlet of the second volute 300 after passing through the condenser, enters into the air supply cavity of the second volute 300 after passing through the second wind wheel 420, and then flows out from the second air outlet. The second air outlet used for the second heat exchange zone 140 generally delivers cold air to the room.

[0039] Reference Figures 1 to 5In order to improve the air supply efficiency of the air-conditioning shell structure and reduce the internal air flow backflow, the first volute 200 is provided with a first guide portion 210, and the first guide portion 210 is arranged at the air inlet of the first volute 200 and is located below the first wind wheel 410. The first guide portion 210 is used to guide the air that has passed the condenser heat exchange into the air supply cavity of the first volute 200, and to guide the hot air that has entered the air supply cavity of the first volute 200 to flow out, thereby reducing the hot air in the air supply cavity of the first volute 200 from flowing back from the gap between the first volute 200 and the first wind wheel 410 to the first heat exchange area 130.

[0040] It should be noted that if Figure 3 and Figure 5 As shown, the first guide portion 210 is circumferentially arranged around the air inlet of the first volute 200, a first guide surface is provided on the side of the first guide portion 210 close to the first heat exchange zone 130, and a second guide surface is provided on the side of the first guide portion 210 away from the first heat exchange zone 130, the first guide surface and the second guide surface are both arc-shaped surfaces, and the convex sides of the first guide surface and the second guide surface are close to the first heat exchange zone 130.

[0041] It can be understood that in the air-conditioning housing structure provided by the embodiment of the first aspect of the utility model, the first air guide 210 is an arc-shaped structure integrally formed with the housing of the first volute 200, and processing and molding are more convenient. In other embodiments, the first air guide 210 can also be an arc-shaped convex portion and an arc-shaped groove provided on the housing of the first volute 200, the arc-shaped convex portion is located at the bottom, the arc-shaped groove is located at the top, the first air guide surface corresponds to the outer wall surface of the arc-shaped convex portion, and the second air guide surface corresponds to the inner wall surface of the arc-shaped groove.

[0042] When the first wind wheel 410 rotates, the hot air in the first heat exchange area 130 flows into the first wind wheel 410 under the guidance of the first guide surface of the first guide part 210, and then enters the air supply cavity of the first volute 200 through the blades of the first wind wheel 410, and the air flows out along the air supply cavity of the first volute 200, wherein the air at the bottom flows to the second guide surface of the first guide part 210, and after being guided by the second guide surface, the air turns and flows back to the air supply cavity of the first volute 200. Compared with the shell structure without the first guide part 210, the air conditioner shell structure provided by the embodiment of the first aspect of the utility model can effectively reduce air reflux.

[0043] Reference Figures 3 to 5 , the length direction perpendicular to the rotation axis of the first wind wheel 410 is the first direction, that is, Figure 5 The up-down direction shown is the first direction. Along the first direction, the minimum distance L between the end of the second guide surface away from the shell and the inner wall of the shell is 1 Less than the minimum distance L between the inner wall of the first wind wheel 410 and the inner wall of the housing 2The advantage of this design is that the air guided by the second guide surface will be blocked by the bottom of the first wind wheel 410, effectively reducing the air entering the first wind wheel 410.

[0044] It should be noted that the direction of the end of the first guide portion 210 away from the housing is parallel to the length direction of the rotating shaft of the first wind wheel 410, that is, the end of the first guide portion 210 away from the housing faces upward. The advantages of this design are: 1. The air guided by the first guide surface enters the first wind wheel 410 vertically upward, and the airflow is stable and not easy to flow across. 2. The air guided by the second guide surface will hit the bottom of the first wind wheel 410 vertically upward, then slow down the flow rate and return to the air supply cavity, effectively reducing air backflow.

[0045] Reference Figures 3 to 5 The first volute 200 is further provided with a second air guide 220, which is located in the air supply cavity of the first volute 200 and at the top of the first wind wheel 410. The second air guide 220 is arranged circumferentially around the double-headed motor 400, and the minimum distance M between the second air guide 220 and the rotating shaft of the double-headed motor 400 is 1 Smaller than the minimum distance M between the inner wall of the first wind wheel 410 and the rotating shaft of the double-headed motor 400 2 .

[0046] It should be noted that a part of the air entering the air supply chamber of the first volute 200 will flow upward, hit the top inner wall of the first volute 200 and then flow toward the rotation axis direction of the first wind wheel 410. The second guide portion 220 can effectively guide the air to flow from the top of the first wind wheel 410 to the inside of the first wind wheel 410, and then flow to the air supply chamber of the first volute 200 through the first wind wheel 410. This design can make the air flow more stable and reduce air cross-flow.

[0047] Understandably, when M 1 Less than M 2 When the air is in the air supply cavity, the second air guide portion 220 will not guide the air to the air supply cavity of the first volute 200, so that the air in the air supply cavity flows in series and the trajectory of the air flow is unstable. This design effectively improves the air supply efficiency.

[0048] It should be noted that the second guide portion 220 is provided with an inclined third guide surface, and the third guide surface is inclined downward toward the central axis of the first wind wheel 410. In the air conditioner housing structure provided in the first embodiment of the utility model, the first guide surface is a curved surface; in other embodiments, the first guide surface can be a plane, an inclined plane.

[0049] Reference Figures 1 to 4The second volute 300 is disposed on the top of the first volute 200 through a mounting portion, and the second volute 300 is provided with two air inlets, which are located at the upper and lower ends respectively and correspond to each other. The minimum distance N1 from the outer wall of the second wind wheel 420 to the central axis of the second wind wheel 420 is greater than the minimum distance N2 from the edge of the air inlet of the second volute 300 to the central axis of the second wind wheel 420.

[0050] It should be noted that the second volute 300 has two air inlets, which can effectively increase the air volume of the second volute 300 and improve the efficiency of cold air output. 1 Greater than N 2 When the air entering the second wind wheel 420 is turned on, it can be ensured that the air entering the second wind wheel 420 will not flow directly into the air supply cavity of the second volute 300 from the gap between the second wind wheel 420 and the second volute 300 without passing through the second wind wheel 420, thereby effectively reducing air cross-flow and improving the stability of air flow, thereby improving air supply efficiency.

[0051] It should be noted that a third guide portion 310 is provided at the air inlet of the second volute 300, and the third guide portion 310 is provided with an inclined fourth guide surface, and the inclination direction of the fourth guide surface is toward the second wind wheel 420. In the air conditioner housing structure provided by the embodiment of the first aspect of the utility model, the fourth guide surface is a curved surface; in other embodiments, the fourth guide surface can also be a plane.

[0052] Reference Figures 1 to 4 The mobile air conditioner provided by the second embodiment of the utility model includes the above-mentioned air conditioner housing structure, condenser assembly 500 and evaporator assembly 600. The condenser assembly 500 is arranged at the bottom, and the evaporator assembly 600 is arranged at the top. The installation is regular, the pipeline layout is reasonable and compact, and the product has strong integrity.

[0053] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
