Figure 5 A grounding structure for a motor of a household appliance according to another embodiment of the present invention is schematically shown, wherein a plug slot 20 is shown in a horizontal cross-sectional view, a grounding plate 30 is shown in a plan view, and the grounding plate 30 is not inserted into the plug slot 20 .

[0059] First, Figure 1As shown, a motor for household appliances according to an embodiment of the utility model includes a motor end cover 10, which is installed at one end of the motor and includes an end cover body 11, a drive device mounting portion 12, a plurality of heat dissipation ribs 13 and a reinforcing rib 14. The end cover body 11 is formed in a cover shape, and a bearing chamber 111 for fixing and mounting a bearing is formed thereon. The drive device mounting portion 12 is arranged on the end cover body 11, and is particularly formed to extend away from the end cover body 11 from one side of the end cover body 11, and is suitable for installing a motor drive device, such as a drive circuit board. A plurality of heat dissipation ribs 13 protrude from the outer surface of the end cover body 11 to increase the heat dissipation area of ​​the motor end cover 10 and improve the heat dissipation performance of the motor end cover 10. The reinforcing rib 14 protrudes from the end cover body 11 more than the plurality of reinforcing ribs 13, so that the structural strength of the motor end cover 10 can be increased on the one hand, and the heat dissipation area of ​​the motor end cover 10 can be further increased on the other hand, and the heat dissipation performance of the motor end cover 10 can be improved. In addition, the reinforcing rib 14 may be formed to be connected to the driving device mounting portion 12 that protrudes away from the end cover body 11 .

[0060] Preferably, the end cover body 11, the drive device mounting portion 12 and the heat dissipation ribs 13 are an integrally formed structure. Optionally, the reinforcing ribs 14 can also be integrally formed with the end cover body 11, the drive device mounting portion 12 and the heat dissipation ribs 13. In addition, preferably, the motor end cover 10 can be at least partially made of a conductive material, that is, the end cover body 11, the drive device mounting portion 12, the heat dissipation ribs 13 and / or the reinforcing ribs 14 can be integrally formed of a conductive material. The conductive material is, for example, aluminum or an aluminum alloy.

[0061] According to one embodiment of the utility model, the motor for household appliances further includes a grounding structure, which includes a plug-in slot 20 and a conductive grounding plate 30, wherein the plug-in slot 20 is formed on the motor end cover 10, and the grounding plate 30 is suitable for being inserted into the plug-in slot 20 to establish an electrical connection with the plug-in slot 20, and further establish an electrical connection with the motor end cover 10.

[0062] The grounding sheet 30 is provided with a resilient elastic structure at the edge, and the elastic structure can be elastically compressed in at least one dimension transverse to the insertion direction of the grounding sheet 30 into the plug slot 20, and by means of the elastic compression, the grounding sheet 30 can be inserted into the plug slot 20. In the plugged state inserted into the plug slot 20, the grounding sheet 30 is locked in the plug slot 20 by means of the rebound effect of the elastic structure.

[0063] More specifically, as shown in Figures 2(A) and Figure 5As shown, the grounding plate 30 has a plate-shaped grounding plate body 31, and the elastic structure includes at least one clamping arm 32 extending integrally from the grounding plate body 31. The grounding plate 30 is inserted into the plug-in slot 20 through the elastic deformation of the clamping arm 32 and is clamped in the plug-in slot 20 by means of the rebound effect of the elastically deformed clamping arm 32.

[0064] As shown in FIG. 2(A) and FIG. 2(B), in a preferred exemplary embodiment, the snap-on arm 32 includes at least one bent snap-on arm 321 extending from a front end 311 of the grounding plate body 31 in the insertion direction and bending and extending rearward in the insertion direction. The bent snap-on arm 321 has a bent connection portion 3211 integrally connected to the grounding plate body 31 and bent backward, and a snap-on portion 3212 further extending backward from the bent connection portion 3211, and the angle between the snap-on portion 3212 and the grounding plate body 31 is an acute angle. Thus, the elastic compressibility of the elastic structure can be provided by the bent connection portion 3211, so that the grounding plate 30 can be easily inserted into the plug-in slot 20; and when the grounding plate 30 is inserted into the plug-in slot 20 and is in the plug-in state, as shown in FIG. Figure 3 As shown schematically, with the help of the rebound effect of the bent connecting portion 3211, the end of the clamping portion 3212 is clamped on the inner wall of the plug-in slot 20 and fits tightly with the inner wall of the plug-in slot 20, thereby realizing the installation and fixation of the grounding plate 30 in the plug-in slot 20 and establishing a stable electrical connection.

[0065] In a preferred embodiment, as shown in FIG. 2(A) and FIG. 2(B), the grounding plate 30 has two bent snap-fit ​​arms 321, which are bent backward from the front end 311 of the grounding plate body 31 toward the opposite side of the grounding plate body 31, thereby providing elastic compression and rebound effects on the opposite sides of the grounding plate body 31, thereby more stably maintaining the grounding plate 30 in the plug slot 20 and better establishing electrical connection.

[0066] Optionally, the two bent clamping arms of the grounding plate 30 may also extend from the front end 311 of the grounding plate body 31 toward the two opposite sides 312 of the grounding plate body 31 ( Figure 5 Alternatively, the grounding plate 30 may include four bent clamping arms extending from the front end 311, wherein two bent clamping arms close to the side edge 312 are bent backward toward the corresponding side edge 312, and the two bent clamping arms in the middle are bent backward toward the opposite side surfaces of the grounding plate body 31. The specific number and arrangement positions of the bent clamping arms in the above-mentioned embodiments are not restrictive, and those skilled in the art can select, combine or modify them as needed.

[0067] like Figure 4 and Figure 5As shown, in another preferred exemplary embodiment, the clamping arm 32 includes at least one protruding clamping arm 322 extending obliquely from the side 312 of the grounding plate body 31 to the rear in the insertion direction. According to the actual size of the grounding plate 30, a plurality of protruding clamping arms can be formed at each side 312 of the grounding plate body 31. Preferably, two protruding clamping arms 322 are formed at each side 312 of the grounding plate body 31. Preferably, each protruding clamping arm 322 is formed with a taper whose size gradually decreases as it approaches the rear end in the insertion direction. Thus, when the grounding plate 30 is inserted, the protruding clamping arm 322 can be easily compressed to facilitate the insertion of the grounding plate 30 into the plug slot 20; and after insertion, due to the rebound effect of the protruding clamping arm 322, its end, especially the relatively sharp end, can be fully clamped on the inner wall of the plug slot 20 and fit closely with the inner wall of the plug slot 20, thereby realizing the installation and fixation of the grounding plate 30 in the plug slot 20 and establishing a stable electrical connection.

[0068] The structure of the grounding plate 30 is not limited to the above two exemplary embodiments. For example, the clamping arm 32 of the grounding plate 30 may include both a bent clamping arm 321 and a protruding clamping arm 322, and the number and setting position of each clamping arm may be adjusted as needed, for example, the protruding clamping arm 322 may also protrude from the side of the grounding plate body 31 (at a position staggered from the bent clamping arm), and each side may be provided with a plurality of bent clamping arms 321 and / or protruding clamping arms 322.

[0069] For each of the above embodiments, advantageously, the inner dimension of the plug slot 20 on the scale where the grounding sheet 30 is suitable for being elastically compressed is smaller than the natural dimension of the grounding sheet 30 on the corresponding scale when it is not compressed. For example, the opening gap of the plug slot 20 is only slightly larger than the minimum compression thickness and / or minimum compression width of the grounding sheet 30 including the elastic structure. In addition, at the opening edge of the opening 21 of the plug slot 20, at least at the section corresponding to the clamping arm 32, a step protruding toward the inside of the opening 21 is formed, thereby further preventing the grounding sheet 30 from falling out of the plug slot 20.

[0070] In an optional embodiment, the grounding structure is provided at the drive device mounting portion 12. Preferably, the plug slot 20 is formed on a side of the drive device mounting portion 12 away from the end cover body 11, and is particularly open away from the end cover body 11. Such a design can facilitate the installation and arrangement of the grounding sheet and the grounding harness connected thereto.

[0071] In an optional embodiment, the plug slot 20 is formed by removing a portion of the conductive material of the motor end cover 10. That is, according to the motor of the utility model, a grounding structure can be formed in a simple and low-cost manner.

[0072] In addition, the reinforcing rib 14 may also be connected to the plug slot 20. According to the actual application of the motor, the reinforcing rib 14 connected to both the drive device mounting portion 12 and the plug slot 20 may additionally provide, for example, shielding against water and / or dust, thereby protecting the drive device and the grounding structure.

[0073] The utility model also provides a household appliance, such as a washing machine, etc. The household appliance has a motor for a household appliance according to any of the above embodiments of the utility model, wherein the grounding plate is connected to a grounding device through a wire.

[0074] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of the present disclosure, even when only a single embodiment is described with respect to specific features. The feature examples provided in the present disclosure are intended to be illustrative, not limiting, unless otherwise stated. In specific implementations, multiple features may be combined with each other as required and as technically feasible. Various substitutions, changes, and modifications may also be conceived without departing from the spirit and scope of the present disclosure.
