Description

Pump assemblies and refrigeration equipment Technical Field

[0001] This utility model relates to the field of water pumps, and more specifically, to a pump assembly and a refrigeration device. Background Technology

[0002] Currently, during the cooling operation of an air conditioner, condensate will be generated on the surface of the heat exchanger. The condensate drips down the surface of the heat exchanger into the condensate drain pan below. In order to drain the condensate to a position higher than the outlet, a drain pump is installed at the condensate drain pan of the air conditioner.

[0003] In related technologies, a drainage pump includes an upper casing and a lower casing, with blades installed in the upper and lower casings. The upper and lower casings are sealed together by a sealing ring. However, sealing the upper and lower casings with a sealing ring makes the assembly process of the drainage pump more complicated. Summary of the Invention

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the first aspect of this utility model proposes a pump assembly.

[0006] The second aspect of this utility model provides a refrigeration device.

[0007] In view of the above, the first aspect of the present invention provides a pump assembly, including a first housing, a second housing, and an impeller. The second housing is fastened to the first housing, and the second housing and the first housing enclose a pump cavity. The impeller is disposed in the pump cavity. A first welding part is provided on the side of the first housing near the second housing, and the first welding part is arranged circumferentially along the pump assembly. A second welding part is provided on the side of the second housing near the first housing, and the second welding part is arranged circumferentially along the pump assembly. The second welding part is connected to the first welding part.

[0008] The pump assembly provided in this application includes a first housing and a second housing, which are interlocked. The second housing and the first housing enclose a pump cavity. The pump assembly also includes an impeller disposed within the pump cavity, which can cooperate with the inner wall of the pump cavity to drive the liquid. A first welded part is provided on the side of the first housing near the second housing, and a second welded part is provided on the side of the second housing near the first housing. The second welded part is connected to the first welded part, thereby achieving a connection between the first housing and the second housing. The connection between the first welded part and the second welded part can seal the gap between the first housing and the second housing, thus eliminating the need for a sealing ring between the first housing and the second housing. During the assembly of the pump assembly, since a sealing ring is no longer needed between the first housing and the second housing, the assembly steps of the pump assembly are reduced, the assembly process of the pump assembly is simplified, and the assembly efficiency of the pump assembly is improved. Furthermore, since a sealing ring is no longer needed between the first housing and the second housing, the structure of the pump assembly is also simplified, reducing the cost of the pump assembly.

[0009] The first welded part is arranged circumferentially along the pump assembly, and the second welded part is arranged circumferentially along the pump assembly, so that the cooperation of the first welded part and the second welded part can seal the gap between the first housing and the second housing in the circumferential direction of the pump assembly, thereby improving the sealing effect between the first housing and the second housing and reducing the probability of liquid leakage between the first housing and the second housing.

[0010] The first housing and the second housing are connected by the first weld and the second weld, so that the first housing and the second housing can form an integral structure. The connection between the first housing and the second housing has a higher strength, thereby improving the stability of the first housing and the second housing, reducing the noise generated by the vibration of the first housing and the second housing during the operation of the pump assembly, and improving the performance of the pump assembly during operation.

[0011] The first and second housings are sealed together via a first and second weld joint. This reduces the probability of poor sealing between the first and second housings due to factors such as misaligned or missing seal rings, effectively improving the pump assembly's pass rate. Specifically, because the seal ring is located inside the first and second housings, it is difficult to detect its absence from the pump assembly's appearance. However, without welding between the first and second housings, they cannot be securely installed, and the first housing will separate from the second. The absence of the first housing is easily noticeable. Therefore, the probability of the first and second housings not being welded is low. Welding between the first and second housings, compared to sealing with a seal ring, improves the pump assembly's pass rate.

[0012] Optionally, in some technical solutions of this utility model, the second welded part protrudes outward from the first welded part in the radial direction of the pump assembly.

The first mating surface and the second mating surface are in contact, and in the radial direction of the pump assembly, the first mating surface and / or the second mating surface extend along a broken line or curve, which increases the area of ​​the mating surface between the first housing and the second housing and further improves the sealing effect between the first housing and the second housing.

[0021] In this technical solution, the second housing also includes an annular portion and reinforcing ribs. Each of the multiple reinforcing ribs extends radially from the annular portion to the first positioning portion along the pump assembly. The two ends of the reinforcing rib are connected to the annular portion and the first positioning portion, respectively, thereby improving the strength of the second housing, reducing the probability of deformation of the second housing, and thus improving the stability of the second housing during the operation of the pump assembly.

Detailed Implementation

[0047] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0049] The pump assembly and refrigeration equipment according to some embodiments of the present invention are described below with reference to Figures 1 to 10.

[0050] In one embodiment of this utility model, as shown in Figures 1, 2, 3, and 4, a pump assembly is provided, including a first housing 100, a second housing 200, and an impeller 300. The second housing 200 is fastened to the first housing 100, and the second housing 200 and the first housing 100 enclose a pump cavity 210. The impeller 300 is disposed within the pump cavity 210. A first welding portion 110 is provided on the side of the first housing 100 near the second housing 200, and the first welding portion 110 is arranged circumferentially along the pump assembly. A second welding portion 220 is provided on the side of the second housing 200 near the first housing 100, and the second welding portion 220 is arranged circumferentially along the pump assembly. The second welding portion 220 is connected to the first welding portion 110.

[0051] In this embodiment, the pump assembly includes a first housing 100 and a second housing 200, which are interlocked. The second housing 200 and the first housing 100 enclose a pump chamber 210. The pump assembly also includes an impeller 300, which is disposed within the pump chamber 210 and can cooperate with the inner wall of the pump chamber 210 to drive the liquid. A first welded portion 110 is provided on the side of the first housing 100 near the second housing 200, and a second welded portion 220 is provided on the side of the second housing 200 near the first housing 100. The second welded portion 220 is connected to the first welded portion 110, thereby achieving a connection between the first housing 100 and the second housing 200. The connection between the first welded portion 110 and the second welded portion 220 can seal the gap between the first housing 100 and the second housing 200, thus eliminating the need for a sealing ring between the first housing 100 and the second housing 200. When assembling the pump assembly, since a sealing ring is no longer required between the first housing 100 and the second housing 200, the assembly steps of the pump assembly are reduced, the assembly process of the pump assembly is simplified, and the assembly efficiency of the pump assembly is improved. Since a sealing ring is no longer required between the first housing 100 and the second housing 200, the structure of the pump assembly is also simplified, and the cost of the pump assembly is reduced.

[0052] The first welded part 110 is arranged circumferentially along the pump assembly, and the second welded part 220 is arranged circumferentially along the pump assembly, so that the cooperation of the first welded part 110 and the second welded part 220 can seal the gap between the first housing 100 and the second housing 200 in the circumferential direction of the pump assembly, thereby improving the sealing effect between the first housing 100 and the second housing 200 and reducing the probability of liquid leakage between the first housing 100 and the second housing 200.

[0053] The first housing 100 and the second housing 200 are connected by the first welding part 110 and the second welding part 220, so that the first housing 100 and the second housing 200 can form an integral structure, and the connection strength between the first housing 100 and the second housing 200 is higher, thereby improving the stability of the first housing 100 and the second housing 200, reducing the noise generated by the vibration of the first housing 100 and the second housing 200 during the operation of the pump assembly, and improving the performance of the pump assembly during operation.

[0054] The first housing 100 and the second housing 200 are sealed by the first weld 110 and the second weld 220. This also reduces the probability of poor sealing between the first housing 100 and the second housing 200 due to factors such as misalignment or omission of the sealing ring, effectively improving the qualification rate of the pump assembly. Specifically, since the sealing ring is located inside the first housing 100 and the second housing 200, it is difficult to detect the absence of the sealing ring from the appearance of the pump assembly. However, if the first housing 100 and the second housing 200 are not welded together, they cannot be fixed together, and the first housing 100 will separate from the second housing 200. The absence of the first housing 100 in the pump assembly is easily detected. Therefore, the probability of the first housing 100 and the second housing 200 not being welded together is low. Thus, sealing between the first housing 100 and the second housing 200 by welding, compared to sealing between the first housing 100 and the second housing 200 by a sealing ring, can improve the qualification rate of the pump assembly.

[0055] Specifically, when welding the first housing 100 and the second housing 200, the side of the first housing 100 closest to the second housing 200 and the side of the second housing 200 closest to the first housing 100 will be melted at high temperature. That is, at the gap between the first housing 100 and the second housing 200, the first housing 100 and the second housing 200 will be partially melted. After the first housing 100 and the second housing 200 are fused together, the melted parts of the first housing 100 and the second housing 200 are cooled and solidified again, thereby realizing the connection between the first housing 100 and the second housing 200.

[0056] The part of the first housing 100 that melts and then solidifies on the side closest to the second housing 200 is the first welded part 110.

[0057] The part of the second housing 200 that is close to the first housing 100, where it melts and then solidifies, is the second welded part 220.

[0058] Specifically, the first housing 100 and the second housing 200 are welded together.

[0059] Both the first housing 100 and the second housing 200 are plastic housings.

[0060] Furthermore, the pump assembly also includes a bracket 700 for mounting the pump assembly to the refrigeration equipment.

[0061] The bracket 700 is a plastic bracket 700.

[0062] It should be noted that the axial direction of the pump assembly mentioned in this application is the direction shown by arrow A in Figure 1.

[0063] The radial direction of the pump assembly mentioned in this application is the direction in which the diameter or radius of the pump assembly is located, such as the direction shown by arrow B in Figure 1.

[0064] The circumferential direction of the pump assembly mentioned in this application is the direction indicated by arrow C in Figure 3.

[0065] This embodiment provides a pump assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0066] As shown in Figures 1 and 2, in the radial direction of the pump assembly, the second welded portion 220 protrudes outward from the first welded portion 110.

[0067] In this embodiment, in the radial direction of the pump assembly, the second welding part 220 protrudes outward from the first welding part 110, so that a platform is formed at the contact position of the first housing 100 and the second housing 200, thereby making the welding between the first housing 100 and the second housing 200 more convenient, further reducing the welding difficulty between the first housing 100 and the second housing 200, and simplifying the welding process between the first housing 100 and the second housing 200.

[0068] This embodiment provides a pump assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0069] As shown in Figures 4, 5 and 6, a first mating surface 120 is provided on the side of the first housing 100 near the second housing 200; a second mating surface 230 is provided on the side of the second housing 200 near the first housing 100, and the second mating surface 230 contacts the first mating surface 120; wherein, in the radial direction of the pump assembly, the first mating surface 120 and / or the second mating surface 230 extend along a broken line or curve.

[0070] In this embodiment, the first housing 100 has a first mating surface 120, and the second housing 200 has a second mating surface 230. The first mating surface 120 and the second mating surface 230 are in contact, and in the radial direction of the pump assembly, the first mating surface 120 and / or the second mating surface 230 extend along a broken line or curve, which increases the area of ​​the mating surface between the first housing 100 and the second housing 200, and further improves the sealing effect between the first housing 100 and the second housing 200.

[0071] Specifically, the first mating surface 120 and the second mating surface 230 extend along the broken line.

[0072] For example: from the inner side of the first mating surface 120 to the outer side of the first mating surface 120, the first mating surface 120 and the second mating surface 230 first extend radially along the pump assembly, the first mating surface 120 and the second mating surface 230 then extend circumferentially along the pump assembly, and finally the first mating surface 120 and the second mating surface 230 extend radially along the pump assembly.

[0073] The first mating surface 120 extends from the inner side to the outer side of the first mating surface 120. The first mating surface 120 and the second mating surface 230 may also extend alternately along the radial and axial directions of the pump assembly multiple times.

[0074] Specifically, the first mating surface 120 and the second mating surface 230 extend along the curve.

[0075] For example, from the inner side of the first mating surface 120 to the outer side of the first mating surface 120, the first mating surface 120 and the second mating surface 230 extend along an arc or wavy line.

[0076] This embodiment provides a pump assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0077] As shown in Figures 1, 4 and 7, the second housing 200 includes a cover plate 240 and a first positioning part 250. The first positioning part 250 is annular and arranged around the cover plate 240. In the axial direction of the pump assembly, the first positioning part 250 abuts against the first housing 100.

[0078] In this embodiment, the second housing 200 includes a cover plate 240 and a first positioning part 250. In the axial direction of the pump assembly, the first positioning part 250 abuts against the first housing 100. The second housing 200 achieves axial positioning between the first housing 100 and the second housing 200 through the cooperation of the first positioning part 250 and the first housing 100, further improving the accuracy of the position between the first housing 100 and the second housing 200.

[0079] Specifically, the cover plate 240 and the first positioning part 250 form a stepped structure.

[0080] This embodiment provides a pump assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0081] As shown in Figures 1, 4 and 6, the first housing 100 includes a body 130 and a second positioning part 140. The second positioning part 140 is annular and arranged circumferentially along the body 130. The second positioning part 140 is embedded inside the first positioning part 250. In the axial direction of the pump assembly, the second positioning part 140 abuts against the cover plate 240.

[0082] In this embodiment, the first housing 100 includes a body 130 and a second positioning part 140. In the axial direction of the pump assembly, the second positioning part 140 abuts against the cover plate 240, so that the first housing 100 achieves axial positioning between the first housing 100 and the second housing 200 through the cooperation of the second positioning part 140 and the cover plate 240, thereby further improving the accuracy of the position between the first housing 100 and the second housing 200.

[0083] Furthermore, the cooperation between the first positioning part 250 and the first housing 100, and the cooperation between the second positioning part 140 and the cover plate 240, results in multiple cooperation relationships between the first housing 100 and the second housing 200. This improves the positional accuracy between the first housing 100 and the second housing 200, enhances the sealing effect between the first housing 100 and the second housing 200, and reduces the probability of liquid leakage between the first housing 100 and the second housing 200.

[0084] Furthermore, in the cooperation between the first positioning part 250 and the second housing 200, and the cooperation between the second positioning part 140 and the cover plate 240, at least one positioning structure can achieve axial positioning between the first housing 100 and the second housing 200.

[0085] Specifically, the main body 130 and the second positioning part 140 form a stepped structure.

[0086] Specifically, the circumferential direction of the body 130 is the same as the circumferential direction of the pump assembly.

[0087] This embodiment provides a pump assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0088] As shown in Figures 1, 4 and 8, the cover plate 240 is provided with a through hole 242, and the second housing 200 also includes an annular portion 260 and reinforcing ribs 270; the annular portion 260 is connected to the cover plate 240 and is arranged circumferentially along the through hole 242; there are multiple reinforcing ribs 270, which are arranged circumferentially along the annular portion 260, and each of the multiple reinforcing ribs 270 extends radially from the annular portion 260 to the first positioning portion 250 along the pump assembly.

[0089] In this embodiment, the second housing 200 further includes an annular portion 260 and reinforcing ribs 270. Each of the plurality of reinforcing ribs 270 extends from the annular portion 260 to the first positioning portion 250 along the radial direction of the pump assembly. The two ends of the reinforcing rib 270 are respectively connected to the annular portion 260 and the first positioning portion 250, thereby improving the strength of the second housing 200, reducing the probability of deformation of the second housing 200, and thus improving the stability of the second housing 200 during the operation of the pump assembly.
