[0038] The specific embodiments of the application have been shown by the above-mentioned drawings, and will be described in more detail hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the application by any means, but to illustrate the concept of the application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0039] In order to make the purpose, technical scheme and advantages of the embodiments of the application more clear, the technical scheme of the embodiments of the application will be clearly and completely described below in combination with the drawings in the embodiments of the application. Obviously, the described embodiments are part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the application. In the case of no conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0040] In the prior art, the volute includes a cover plate and a side wall plate vertically arranged on one side of the cover plate along the spiral line, the side wall plate and the cover plate enclose an air duct, an impeller is rotationally arranged in the air duct, an air inlet is formed in the cover plate and communicates with the air duct, the air inlet is axially opposite to the impeller, the side wall plate and the cover plate form an air outlet on the side of the side wall plate, and the air outlet is located on one side of the impeller.

[0041] In some scenarios, it is necessary for the cabinet air conditioner to have a large air volume, but as the air volume increases, the noise of the cabinet air conditioner will also increase. In order to increase the air volume of the air conditioner, the impeller is usually enlarged or the air outlet is enlarged, but this will obviously increase the space occupation of the air duct structure, which is not feasible when the size of the air conditioner is limited. In addition, in order to avoid the noise of the cabinet air conditioner being too large after the air volume is increased, a gasket is usually attached to the air duct of the cabinet air conditioner or the profile of the side wall plate is adjusted to reduce the noise, but the specific implementation is relatively complex and inconvenient, and the air volume is easily limited.

[0042] Therefore, the volute structure of the existing cabinet air conditioner is prone to not being able to balance the wind increasing effect and the noise reduction effect of the air conditioner.

[0043] In order to overcome the defects in the prior art, the volute structure and the air conditioner provided in the embodiments of the present application, the volute structure includes a cover plate and a side wall plate arranged on one side of the cover plate, and the side wall plate and the cover plate can enclose an air duct to facilitate the circulation of airflow in the air conditioner.

[0044] Among them, at least part of the side wall plate is inclined to the outside of the air conditioner relative to the cover plate, by setting the side wall plate to be inclined outward, the surface area of the side wall plate can be increased to improve the flow guiding effect of the side wall plate on the airflow in the air duct, thereby improving the flow characteristics of the airflow in the air duct, reducing the airflow resistance and reducing the airflow noise of the air conditioner.

[0045] And, the side wall plate is arranged to be inclined outward, which can increase the space of the air duct, improve the capacity of the air duct for airflow, and thus increase the circulation of airflow in the air duct, so as to increase the air volume of the air conditioner. Therefore, the volute structure and the air conditioner provided in the embodiments of the present application can balance the wind increasing effect and the noise reduction effect of the air conditioner.

[0046] The content of the present application will be described in detail below with reference to the drawings, so that those skilled in the art can more clearly and detailedly understand the content of the present application.

[0047] Referring to Figures 1 to 6 Fig. 1, the embodiments of the present application provide a volute structure 100, which includes:

[0048] a cover plate 110;

[0049] a side wall plate 120 connected to the cover plate 110, and the side wall plate 120 and the cover plate 110 jointly enclose at least part of an air duct;

[0050] At least a portion of the side panel 120 is inclined outward relative to the cover plate 110.

[0051] It is understandable that the cover plate 110 of the volute structure 100 can be provided with one or two. When only one cover plate 110 is provided, such as Figures 1 to 3 As shown, a cover plate 110 is provided on one side of the side panel 120, and the side of the side panel 120 opposite to the cover plate 110 is connected to the back plate 210 of the air conditioner body 200. Thus, the cover plate 110, the side panel 120 and the back plate 210 together form an air duct. In this way, the cover plate 110 on one side can be omitted, thereby saving space occupied by the volute structure 100.

[0052] When two cover plates 110 are provided on the volute structure 100, the two cover plates 110 are respectively covered on the opposite sides of the side panel 120 so that the two cover plates 110 and the side panel 120 together form an air duct. This application does not limit this.

[0053] The profile of the side panel 120 is spiral-shaped, and the back panel 210 has an air inlet 111. The side panel 120 and the cover plate 110 form an air outlet 112 on one side of the side panel 120. In this way, the impeller 220 can be installed inside the side panel 120 and the impeller 220 is opposite to the air inlet 111. When the impeller 220 rotates, it can draw air into the air duct from the air inlet 111. The airflow flows along the spiral formed by the side panel 120 to the air outlet 112 and is discharged.

[0054] In existing volute structures 100, the side panels 120 are all vertically arranged relative to the cover plate 110. However, in the volute structure 100 provided in this application embodiment, at least a portion of the side panels 120 are inclined outward relative to the cover plate 110. That is, relative to the cover plate 110 where the air inlet 111 is provided, the angle between the inner wall of at least a portion of the side panels 120 and the cover plate 110 is an obtuse angle, and the angle between the outer wall of the at least a portion of the side panels 120 and the cover plate 110 is an acute angle.

[0055] It is understood that, compared to setting the side panel 120 perpendicular to the cover plate 110, at least part of the side panel 120 in this application is set outward relative to the cover plate 110. Under the same height dimension perpendicular to the cover plate 110, the surface area of ​​the side panel 120 can be larger, thereby enabling the side panel 120 to more fully guide the airflow in the air duct, thereby improving the airflow guiding effect.

[0056] Moreover, the outward tilt of the side panel 120 increases the space inside the air duct, thereby increasing the air volume capacity of the volute structure 100 and the air duct.

[0057] Therefore, the volute structure 100 provided by the embodiment of the present application comprises a cover plate 110 and a side wall 120 arranged on one side of the cover plate 110, and the side wall 120, the cover plate 110 and the air conditioner can form an air duct so as to facilitate the airflow circulation in the air conditioner.

[0058] At least part of the side wall 120 is arranged to be inclined to the outside of the air conditioner relative to the cover plate 110. By arranging the side wall 120 to be inclined outward, the surface area of the side wall 120 can be increased, so as to improve the airflow guiding effect of the side wall 120 on the airflow in the air duct, thereby improving the flow characteristics of the airflow in the air duct, reducing the airflow resistance and reducing the airflow noise of the air conditioner.

[0059] In addition, the side wall 120 is arranged to be inclined outward, so as to increase the space of the air duct, improve the capacity of the air duct for the airflow, thereby increasing the circulation of the airflow in the air duct and increasing the air volume of the air conditioner. In this way, the volute structure 100 and the air conditioner provided by the embodiment of the present application can take into account the wind increasing and noise reducing effects of the air conditioner.

[0060] In some embodiments, referring to FIG. 1, Figures 1 to 6 As shown in FIG. 1, the side wall 120 comprises:

[0061] a volute part 121 connected to the cover plate 110, the volute part 121 being used for accommodating an impeller 220;

[0062] a volute tongue part 122 connected to one side of the volute part 121 and connected to the cover plate 110, the volute tongue part 122 and the cover plate 110 forming an air outlet 112 of the communication air duct;

[0063] Part of the volute tongue part 122 is inclined relative to the cover plate 110.

[0064] It can be understood that the volute part 121 is used for accommodating the impeller 220, and the impeller 220 is opposite to the air inlet 111 on the cover plate 110, so that the volute part 121 corresponds to the air inlet part of the air duct.

[0065] The volute tongue part 122 is located on one side of the volute part 121 and forms the air outlet 112 with the cover plate 110 and the back plate 210 of the air conditioner main body 200, so that the volute tongue part 122 corresponds to the air outlet part of the air duct.

[0066] In this way, by arranging part of the volute tongue part 122 to be inclined relative to the cover plate 110, the airflow outflow direction and speed distribution at the air outlet 112 can be further adjusted, so that the airflow can flow out more smoothly, the airflow turbulence and backflow can be reduced, the air outlet efficiency and noise reduction effect of the air conditioner can be improved, and the stability and uniformity of the air supply can be enhanced.

[0067] In other embodiments, the at least part of the volute portion 121 can be further inclined relative to the cover plate 110 to increase the air flow accommodating space of the volute portion 121 and to increase the air volume.

[0068] The air flow in the volute portion 121 can be made smoother, and the cooperation between the volute portion 121 and the impeller 220 can be optimized to make the impeller 220 rotate more smoothly in the volute portion 121 and reduce the friction noise between the impeller 220 and the air flow.

[0069] Further, referring to FIG. 1, the volute tongue portion 122 includes: Figures 2 to 7

[0070] A first volute tongue segment 1221 connected to the volute portion 121 and tangent to the volute portion 121;

[0071] A second volute tongue segment 1222 connected to the volute portion 121 and spaced apart from the first volute tongue segment 1221 on a side of the first volute tongue segment 1221 facing the volute portion 121;

[0072] The second volute tongue segment 1222 is inclined relative to the cover plate 110.

[0073] It can be understood that the first volute tongue segment 1221 is tangent to the volute portion 121, which can make the first volute tongue segment 1221 and the volute portion 121 form a spiral structure, the inner wall of the first volute tongue segment 1221 naturally extends along the inner wall of the volute portion 121, so that the air flow entering the volute tongue portion 122 is smoother and the air flow disturbance is reduced.

[0074] The second volute tongue segment 1222 is spaced apart from the first volute tongue segment 1221 and located on a side of the first volute tongue segment 1221 facing the volute portion 121, so that the first volute tongue segment 1221 cooperates with the second volute tongue segment 1222 to stably guide the air flow in the volute portion 121.

[0075] Based on the spiral design of the side wall 120, the air flow tends to flow towards the second volute tongue segment 1222 when flowing through the volute tongue portion 122 and flows out of the air outlet 112 along the second volute tongue segment 1222.

[0076] Therefore, the second volute tongue segment 1222 is inclined relative to the cover plate 110, which can effectively guide and adjust the air flow to be more orderly when flowing out of the volute tongue portion 122, reduce the turbulence and backflow of the air flow, and further achieve the effect of stable wind increase and noise reduction.

[0077] ​And, in some embodiments, the first volute tongue segment 1221 can also be arranged to be inclined relative to the cover plate 110, and the inclination direction of the first volute tongue is opposite to that of the second volute tongue segment 1222, so that the first volute tongue segment 1221 and the second volute tongue segment 1222 can both be inclined towards the outside of the cover plate 110, further improving the wind increasing and noise reducing effect of the volute structure 100.

[0078] In specific implementation, referring to Figure 6 It is shown that the inclination angle a of the second volute tongue segment 1222 relative to the cover plate 110 is greater than or equal to 5° and less than or equal to 15°.

[0079] It can be understood that arranging the inclination angle a of the second volute tongue segment 1222 relative to the cover plate 110 to be 5° to 15° can more effectively adjust the outflow direction and speed distribution of the airflow, and reduce the friction between the airflow and the volute tongue portion 122 when flowing, thereby reducing noise. Moreover, arranging the inclination angle of the second volute tongue segment 1222 in this range can also prevent the inclination angle of the second volute tongue segment 1222 from being too large, thereby making the processing of the volute structure 100 more difficult, and avoiding the volute structure 100 occupying more space and resulting in a lower space utilization rate.

[0080] For example, in the present embodiment, the inclination angle a of the second volute tongue segment 1222 relative to the cover plate 110 is 6°, and in other embodiments, a can also be arranged to be 5°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14° or 15°, etc., which is not limited in the present application.

[0081] And, in some embodiments, referring to Figures 3 to 7 It is shown that the distance between the second volute tongue segment 1222 and the first volute tongue segment 1221 gradually increases from the end close to the volute portion 121 to the end away from the volute portion 121.

[0082] It can be understood that in this way, the volute tongue portion 122 forms a flared structure with gradually increasing diameter on one side of the volute portion 121, so that when the air in the volute portion 121 initially flows to the volute tongue portion 122, it can be concentrated together by the volute tongue portion 122 for guidance, so that the airflow quickly forms a flow trend along the extension direction of the volute tongue portion 122 when entering the volute portion 121, avoiding dispersion and disorder of the airflow.

[0083] And as the airflow further flows along the volute tongue portion 122, the space of the volute tongue portion 122 becomes more and more abundant due to the gradually increasing distance between the second volute tongue segment 1222 and the first volute tongue segment 1221, reducing the retention and obstruction of the airflow, improving the flow efficiency of the airflow, and thereby increasing the air volume of the air outlet 112 of the volute tongue portion 122.

[0084] And, as the spacing between the second volute tongue segment 1222 and the first volute tongue segment 1221 gradually increases, the increase is relatively smooth, which helps the airflow to be more stable during the flow process, avoids the airflow from rubbing against the volute tongue segment due to sudden changes in the spatial size, and reduces the noise of the air flow in the volute tongue portion 122.

[0085] Further, referring to Figures 4 to 7 It is shown that the inner side walls of the first volute tongue segment 1221 and the second volute tongue segment 1222 are both flat.

[0086] It can be understood that, by setting the wall surfaces of the first volute tongue segment 1221 and the second volute tongue segment 1222 as flat, the processing difficulty of the volute structure 100 is relatively low, and the volute structure 100 is easier to process and manufacture. At the same time, the flat wall surface of the structure can make the volute tongue portion 122 more stable, facilitate uniform distribution of stress, and avoid deformation of the volute tongue portion 122 and the volute structure 100 due to local stress concentration.

[0087] And, the flat wall surface is more likely to form a regular airflow guide surface, making the airflow flow path of the volute tongue portion 122 more stable, reducing the vortex generated by the change of the wall surface, improving the stability and uniformity of the airflow flow, and ensuring the supercharging and noise reduction effect of the volute structure 100.

[0088] In addition, in some embodiments, referring to Figures 2 to 4 It is shown that a support rib plate 1211 is arranged between the second volute tongue segment 1222 and the volute portion 121, and the support rib plate 1211 has a reinforcing rib 1212.

[0089] It can be understood that, as the second volute tongue segment 1222 is arranged obliquely relative to the cover plate 110, when the impeller 220 rotates or other components in the air conditioner main body 200 vibrate, the structural stability of the second volute tongue segment 1222 is poor.

[0090] To this end, the support rib plate 1211 is arranged between the second volute tongue segment 1222 and the volute portion 121, which can provide support for the second volute tongue segment 1222, effectively increase the structural rigidity and stability between the second volute tongue segment 1222 and the volute portion 121, and prevent the second volute tongue segment 1222 and the volute tongue portion 122 from deforming or shaking during the operation of the air conditioner.

[0091] And, the reinforcing rib 1212 arranged on the support rib plate 1211 in a crisscross manner can further improve the strength of the support rib plate 1211, effectively disperse stress, and avoid local stress concentration of the support rib plate 1211 when stressed, which can cause damage.

[0092] And, in specific implementation, the support rib plate 1211, the cover plate 110 and the side wall plate 120 are integrally injection molded.

[0093] It can be understood that, compared with the existing volute structure 100 which is usually a foam piece, the volute structure 100 of the embodiment of the present application sets the support rib plate 1211, the cover plate 110 and the side wall plate 120 as an integral injection molding piece, so that the overall structural strength of the volute structure 100 is higher, and thus the thickness of the wall plate of the volute structure 100 can be reduced.

[0094] In this way, without changing the external space occupied by the volute structure 100, the internal space of the volute structure 100 can be effectively increased by reducing the thickness of the wall plate of the volute structure 100, and thus the airflow flux of the volute structure 100 is improved, so that the air volume of the air conditioner is increased.

[0095] In the embodiment, the thickness of the wall plate of the volute structure 100 is greater than or equal to 2 mm and less than or equal to 4 mm.

[0096] It can be understood that the thickness of the wall plate of the volute structure 100 made of the existing foam piece is usually about 8 mm, and the thickness of the wall plate of the volute structure 100 can be controlled to be 2 mm to 4 mm by setting the volute structure 100 as an integral injection molding piece, so that the thickness of the wall plate of the volute structure 100 is significantly reduced, the internal space of the volute structure 100 is significantly increased, and the effect of increasing the air volume is ensured.

[0097] For example, in the embodiment, the thickness of the wall plate of the volute structure 100 is set to 3 mm, and in other embodiments, the thickness of the wall plate can also be set to 2 mm or 4 mm, which is not limited in the present application.

[0098] The embodiment of the present application also provides an air conditioner, which comprises an air conditioner main body 200 and the volute structure 100 in any of the above embodiments arranged on the air conditioner main body 200.

[0099] The volute structure 100 has been described in detail in the above embodiments, and will not be described here.

[0100] In summary, the air conditioner provided by the embodiment of the present application sets the volute structure 100, which comprises a cover plate 110 and a side wall plate 120 arranged on one side of the cover plate 110, and the side wall plate 120 and the cover plate 110 can enclose an air duct so as to facilitate the flow of air in the air conditioner.

[0101] At least part of the side wall plate 120 is arranged to be inclined to the outside of the air conditioner relative to the cover plate 110, and by arranging the side wall plate 120 to be inclined outward, the surface area of the side wall plate 120 can be increased to improve the flow guiding effect of the side wall plate 120 on the airflow in the air duct, and thus the flow characteristics of the airflow in the air duct are improved, the airflow resistance is reduced, and the airflow noise of the air conditioner is reduced.

[0102] And, the side wall plate 120 is outwardly inclined to be arranged, so that the space of the air duct is increased, the capacity of the air duct for airflow is improved, and the flow capacity of the airflow in the air duct is increased, so that the air volume of the air conditioner is increased. Therefore, the volute structure 100 and the air conditioner provided by the embodiment of the present application can increase the air volume and reduce the noise of the air conditioner.
