DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0038] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the prior art, when installing a washing machine motor, a positioning ring must be installed at the bearing seat first, and then the stator of the motor is positioned by the positioning ring. However, since each washing machine needs to perform the above operation, the production cost is high.

[0041] In view of this, if Figure 1-5 As shown, the utility model provides a washing machine motor mounting structure, including a bearing seat arranged at the bottom of an outer drum 1, and a positioning portion 4 is protruded on the side of the bearing seat away from the outer drum 1, and the positioning portion 4 is used for positioning and connecting with the inner peripheral wall of the motor stator.

[0042] Compared with the prior art in which a positioning ring is installed for positioning when the motor stator is installed, the positioning portion 4 of the utility model is directly arranged on the bearing seat, so that the user can directly install the motor stator, saving the operation process.

[0043] Preferably, in the present invention, the positioning portion 4 and the bearing seat are integrally formed.

[0044] On the other hand, since the positioning part 4 of the utility model is directly arranged on the bearing seat, a plurality of positioning parts 4 can be arranged at intervals from each other under the premise of playing a limiting role. As the spacing between adjacent positioning parts 4 increases, the material cost required for the positioning part 4 is reduced compared with the positioning ring.

[0045] Specifically, Figure 2 As shown, the bearing seat in the present invention can be set as an annular structure, the center of which is configured as a transmission shaft mounting hole 5 of the washing machine, and a plurality of positioning parts 4 are arranged at intervals along the circumferential direction on the outer periphery of the transmission shaft mounting hole 5.

[0046] Furthermore, in addition to the positioning portion 4, a plurality of stator mounting portions 302 are also provided on the periphery of the transmission shaft mounting hole 5. The motor stator can be set on the bearing seat through the stator mounting portion 302, and the positioning portion 4 is set between the stator mounting portion 302 and the transmission shaft mounting hole 5.

[0047] The positioning is performed using the straight line formed between the center of the drive shaft mounting hole 5 and the stator mounting portion 302. The positioning portion 4 can be arranged on the above straight line, that is, the center of the drive shaft mounting hole 5, the positioning portion 4 and the stator mounting portion 302 are on the same straight line. Alternatively, since a plurality of positioning portions 4 are arranged on the periphery of the drive shaft mounting hole 5, the positioning portion 4 may not be on the above straight line.

[0048] like Figure 3 and Figure 4 As shown, the positioning portion 4 includes a wide portion 401 , which extends a certain distance along the circumference of the transmission shaft mounting hole 5 . When the motor of the washing machine is installed, the motor stator is arranged in contact with the outer ring wall of the wide portion 401 .

[0049] As the extension distance of the wide portion 401 increases, the contact area between the motor stator and the positioning portion 4 also increases. At this time, in addition to better positioning the electronic stator, the stress between the motor stator and the positioning portion 4 can be reduced as much as possible, thereby maximizing the service life of the electronic stator and the positioning portion 4.

[0050] In order to ensure that the positioning portion 4 can provide a better positioning effect for the motor stator, the outer peripheral end of the positioning portion 4 in the utility model extends outward in an arc shape from the protruding top wall of the positioning portion 4 to the bearing seat, that is, if the positioning portion 4 on the bearing seat is cut along the radial direction of the transmission shaft mounting hole 5, the cross-section of the positioning portion 4 extends approximately in an arc shape to the bearing seat.

[0051] By providing the positioning portion 4, the process of installing the positioning ring in the prior art can be saved, but the bearing seat of the utility model includes two components, the outer cylinder rear 2 and the bearing seat body 3. The outer cylinder rear 2 is an annular structure, and its inner ring side is arranged on the outer periphery of the bearing seat body 3. Since the materials used for the two components are inconsistent, when the injection molding is cooled, the shrinkage of the two materials is inconsistent, and there may be a flash gap between the outer cylinder rear 2 and the bearing seat body 3 that are originally fitted together. In severe cases, it may even cause the bearing seat body 3 to fall off.

[0052] In order to avoid the above situation, the positioning portion 4 of the utility model is arranged at the end of the outer cylinder rear 2 away from the outer cylinder 1, and the positioning portion 4 is arranged at the connection between the bearing seat body 3 and the outer cylinder rear 2. When the outer cylinder rear 2 shrinks during injection molding cooling, the positioning portion 4 integrally formed with the outer cylinder rear 2 can limit its shrinkage to a certain extent, thereby reducing the generation of flash gaps between the outer cylinder rear 2 and the bearing seat body 3.

[0053] Specifically, in the utility model, the middle part of the bearing seat body 3 is protruding outward, the outer cylinder rear 2 covers the outer peripheral edge of the protruding end face of the bearing seat body 3, and the two ends of the positioning part 4 are respectively connected to the two sides of the outer cylinder rear 2 covering the outer peripheral edge of the protruding end face of the bearing seat body 3.

[0054] When the outer cylinder rear 2 on both sides of the bearing seat body 3 has a tendency to retract, since the positioning part 4 connects the outer cylinder rear 2 on both sides, the retraction tendency of the outer cylinder rear 2 on both sides of the bearing seat body 3 is restricted, thereby reducing the generation of flash gaps between the outer cylinder rear 2 and the bearing seat body 3, ensuring the stability of the connection between the outer cylinder rear 2 and the bearing seat body 3.

[0055] In the present invention, the outwardly protruding portion of the bearing seat body 3 includes an inner ring portion 301 and a stator mounting portion 302 , wherein the stator mounting portion 302 is protrudingly disposed on the outer peripheral wall of the inner ring portion 301 .

[0056] Correspondingly, the outer cylinder 2 includes a first covering structure 201 covering the stator mounting portion 302 and a second covering structure 202 covering the inner ring portion 301 .

[0057] The first covering structure 201 is extended in an arc shape along the edge of the protruding end surface of the stator mounting portion 302 , and the first covering structure 201 is an open structure, and its end facing away from the outer cylinder 1 is open.

[0058] The second covering structure 202 is circumferentially extended at the outer peripheral edge of the protruding end surface of the inner ring portion 301 and connected to the first covering structure 201 . The second covering structure 202 is also an open structure, and its end facing away from the outer tube 1 is open.

[0059] The two ends of the wide portion 401 of the positioning portion 4 are respectively connected to the two ends of the connection between the second covering structure 202 and the first covering structure 201 to limit the retraction tendency of the first covering structure 201 and the second covering structure 202 here, so that they are in a fit state with the bearing seat body 3 they cover.

[0060] Furthermore, the positioning portion 4 of the present invention further includes an auxiliary connecting portion 403 , which is connected to the outer ring end of the wide portion 401 .

[0061] Specifically, the auxiliary connection portion 403 extends a certain length along the circumference of the inner ring portion 301, and either end of the length extension direction needs to be connected to the inner wall of the first covering structure 201. At this time, in addition to the two ends of the wide portion 401 being connected to the first covering structure 201 and the second covering structure 202, the setting of the auxiliary connection portion 403 increases the connection area between the positioning portion 4 and the outer cylinder rear 2, thereby increasing the structural stability of the positioning portion 4, so that it can provide a more stable positioning effect for the motor stator.

[0062] Preferably, the two ends of the auxiliary connection part 403 in the length extension direction can be respectively connected to the two ends of the arc of the first coating structure 201. In this case, the auxiliary connection part 403 is used to increase the connection area between the positioning part 4 and the outer cylinder 2, thereby increasing the structural stability of the positioning part 4. Since its two ends are respectively connected to the two ends of the arc of the first coating structure 201, when the first coating structure 201 is cooled during injection molding and has a tendency to shrink, the auxiliary connection part 403 can also limit its shrinkage tendency, so that it maintains a state of close connection with the outer wall of the stator mounting part 302.

[0063] Furthermore, the positioning portion 4 in the present invention further includes a narrow portion 402 disposed perpendicularly to the wide portion 401 , and the narrow portion 402 extends a certain length along the circumference of the second covering structure 202 , and at this time, the wide portion 401 and the narrow portion 402 form a T-shaped structure.

[0064] The wide portion 401 of the positioning portion 4 is connected to the auxiliary connecting portion 403 via the narrow portion 402 . Either end of the narrow portion 402 in the length extension direction can be connected to the second covering structure 202 , or both ends of the narrow portion 402 in the length extension direction can be connected to the second covering structure 202 .

[0065] When either end of the narrow portion 402 is connected to the second covering structure 202 , the narrow portion 402 can increase the connection area between the positioning portion 4 and the outer cylinder rear 2 , thereby further increasing the structural stability of the positioning portion 4 .

[0066] When both ends of the narrow portion 402 in the length extension direction are connected to the second covering structure 202, the narrow portion 402 at this time is not only used to increase the connection area between the positioning portion 4 and the outer cylinder rear 2, thereby increasing the structural stability of the positioning portion 4, but also, because both ends of its length extension direction are connected to the second covering structure 202, when the second covering structure 202 is cooled during injection molding and has a tendency to shrink, the narrow portion 402 can also limit its shrinkage tendency, so that it maintains a state of being fitted and connected with the outer peripheral wall of the inner ring portion 301.

[0067] Preferably, the positioning portion 4 of the present invention is further provided with an auxiliary support portion 404 between the wide portion 401 and the auxiliary connection portion 403 . The auxiliary support portion 404 connects the wide portion 401 and the auxiliary connection portion 403 into a whole, further increasing the structural stability of the positioning portion 4 .

[0068] The auxiliary support portion 404 can be configured as a rod-shaped structure, one end of which is connected to the wide portion 401 and the other end is connected to the auxiliary connection portion 403. In this case, in order to ensure the connection function, multiple auxiliary support portions 404 need to be provided.

[0069] Alternatively, the cross-section of the auxiliary support portion 404 can also be set to be triangular-shaped and extend a certain distance along the outer ring wall of the wide portion 401. At this time, its adjacent two side walls are respectively connected to the wide portion 401 and the auxiliary connection portion 403, thereby fully ensuring the connection area and improving the integrity of the auxiliary connection portion 403 and the wide portion 401.

[0070] If the width of the auxiliary connection part 403 is smaller than the width of the wide part 401, the width of the auxiliary support part 404 can be consistent with the width of the wide part 401. At this time, the auxiliary support part 404 outside the auxiliary connection part 403 can be connected to the second covering structure 202, which can still increase the structural stability of the positioning part 4.

[0071] Taking into account that the auxiliary support portion 404 is a structure protruding from the outer ring wall of the wide portion 401, in order to prevent the auxiliary support portion 404 from affecting the normal installation of the motor stator, the sum of the thickness of the auxiliary support portion 404 and the wide portion 401 needs to be adapted to the thickness of the second covering structure 202. On the premise of increasing the structural stability of the positioning portion 4 as much as possible, the sum of the thickness of the auxiliary support portion 404 and the wide portion 401 can be equal to the thickness of the second covering structure 202, or slightly exceed the thickness of the second covering structure 202.

[0072] On the other hand, considering that the auxiliary connecting portion 403 and the narrow portion 402 extend from the end of the outer cylinder 1 away from the outer cylinder 1 at the rear 2 of the outer cylinder to the direction close to the outer cylinder 1, in order to avoid interference between the bearing seat body 3 and the auxiliary connecting portion 403 and the narrow portion 402, as shown in FIG. Figure 4 and Figure 5As shown, in the present invention, a recess 303 is further provided at the connection between the stator mounting portion 302 and the outer peripheral wall of the inner ring portion 301 for accommodating the auxiliary connecting portion 403 and the narrow portion 402 of the positioning portion 4 .

[0073] The length of the recess 303 matches the length of the narrow portion 402 and the auxiliary connecting portion 403 . To facilitate the processing of the recess 303 , the narrow portion 402 and the auxiliary connecting portion 403 extend at the same distance in the direction close to the outer tube 1 .

[0074] When the narrow portion 402 and the auxiliary connecting portion 403 of the positioning portion 4 are embedded in the recess 303, in addition to the auxiliary connecting portion 403 and the narrow portion 402 increasing the structural stability of the positioning portion 4, the recess 303 can also limit the positioning portion 4 by limiting the radial displacement of the auxiliary connecting portion 403 and the narrow portion 402 along the inner ring portion 301, thereby enabling the positioning portion 4 to have a better limiting effect on the motor stator.

[0075] When the motor stator is connected to the stator mounting portion 302 by bolt connection, in order to ensure the connection strength, the side wall of the stator mounting portion 302 needs to have a certain thickness. Therefore, in the utility model, the stator mounting portion 302 and the recess 303 need to be arranged at intervals. The bearing seat body 3 arranged between the stator mounting portion 302 and the recess 303 can, on the one hand, ensure the side wall thickness of the stator mounting portion 302 and ensure the stability of the connection between the motor stator and the bearing seat. On the other hand, this part of the bearing seat body 3 can also limit the radial outward displacement of the auxiliary connecting portion 403 of the positioning portion 4 along the inner ring portion 301, thereby increasing the structural stability of the positioning portion 4, thereby further increasing the stability of the motor stator when installed on the bearing seat.

[0076] The utility model also provides a washing machine, comprising an outer drum 1 and a motor arranged at the bottom of the outer drum 1. To facilitate the installation of the motor, the bottom of the outer drum 1 is provided with the above-mentioned washing machine motor installation structure.

[0077] Specifically, when installing the motor, the user first abuts the inner peripheral wall of the electronic stator against the outer annular wall of the wide portion 401 of the positioning portion 4, then fixes the motor stator through the stator mounting portion 302, and finally installs the motor rotor.

[0078] Compared with the prior art, the utility model provides a positioning portion 4 on the bearing seat, so that the user can directly limit the motor stator through the positioning portion 4, thereby saving the process of installing the positioning ring and reducing the production cost.

[0079] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
