Therefore, it should not be understood as a limitation on the present invention.

[0026] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" 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. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figure 1-3As shown, in order to solve the problem of high cost of motor positioning and installation of washing machines in the prior art, the motor positioning structure 1 of the washing machine of the present invention includes an inner ring 11 and an outer ring assembly 12 sleeved on the inner ring 11, the washing machine includes an outer drum 3, a bearing seat 4 and a motor 2, the bearing seat 4 is arranged on the outer drum 3, the motor 2 is installed on the bearing seat 4, in order to ensure the stability and position accuracy of the motor 2 when it is installed on the bearing seat 4, before the motor 2 is installed, the motor positioning structure 1 is installed on the bearing seat 4, the motor positioning structure 1 is used to position the motor 2, and then the stator 21 of the motor 2 is sleeved on the outer ring assembly 12 of the motor positioning structure 1, so that the outer ring assembly 12 can position the stator 21, and the stator 21 is fixed on the bearing seat 4 after the stator 21 is positioned. Generally, the stator 21 can be fixed to the bearing seat 4 by using screws 211, and the motor positioning structure 1 is taken out after the stator 21 is fixed, so that the motor positioning structure 1 can be reused, and in order to facilitate the removal of the motor positioning structure 1, a handle 113 can be provided on the inner ring 11. After the motor positioning structure 1 is taken out, the rotor 22 of the motor 2 is fixed on the rotating shaft 41. Generally, the center of the rotor 22 is fixed on the rotating shaft 4 by bolts 221. The inner ring 11 and the outer ring assembly 12 of the motor positioning structure 1 can be set in a detachable connection form. For example, the inner ring 11 and the outer ring assembly 12 are connected by magnetic attraction. At this time, a support chassis 111 can be set on the inner ring 11. The support chassis 111 and / or the outer ring assembly 12 have magnetism, so that the support chassis 111 and the outer ring assembly 12 are connected by magnetic attraction. Figure 1 As shown, the support chassis 111 can support the outer ring assembly 12 sleeved on the inner ring 11. When the outer ring assembly 12 includes multiple outer rings 121, that is, an appropriate number of outer rings 121 are selected according to the size of the motor 2 and are sleeved in sequence to form the outer ring assembly 12. In order to prevent the outer ring 121 from rotating on the inner ring 11, a groove 112 can be provided on the inner ring 11, and a protrusion 122 can be correspondingly provided on the outer ring 121. When the outer ring 121 is installed on the inner ring 11, the protrusion 122 is clamped in the groove 112. It should be noted that the support chassis 111 is set to have magnetism. At this time, the support chassis 111 is magnetically connected to the bearing seat 4, which can ensure that the motor positioning structure 1 can be quickly removed from the bearing seat 4 after the stator 21 is positioned. In addition, since the motor positioning structure 1 is sleeved on the bearing seat 4, the accuracy of the motor positioning structure 1 positioning the motor 2 can be guaranteed.

[0028] It should also be noted that when the inner ring 11 and the outer ring assembly 12 are connected by magnetic attraction, the multiple outer rings 121 of the outer ring assembly 12 can be connected to the supporting chassis 111. At this time, the supporting chassis 111 supports all the outer rings 121. The inner outer ring 121 in the outer ring assembly 12 can directly contact and magnetically attract the supporting chassis 111, while the outer outer ring 121 is snap-fitted or magnetically connected to the adjacent outer ring 121 so that the entire outer ring assembly 12 is fixed on the inner ring 11. The above is not restrictive and can be set according to the needs of technicians in this field. Therefore, the above are all within the protection scope of the present invention.

[0029] The outer ring assembly 12 can be configured to nest multiple outer rings 121 together. Of course, it can also be configured in other forms. For example, an adjustment assembly (not shown in the figure) is provided in the outer ring assembly 12. The adjustment assembly can adjust the outer diameter of the outer ring assembly 12. The outer diameter of the outer ring assembly 12 is adjusted according to the size requirements of the motor 2, thereby achieving the positioning of the stator 21 of the motor 2 by the outer ring assembly 12. The above is not restrictive and can be configured according to the needs of technicians in this field.

[0030] Of course, since the motor positioning structure 1 is a reusable component, in order to ensure that the motor positioning structure 1 can position different stators 21 and simplify the structure of the motor positioning structure 1, the outer ring component 12 can also include only one outer ring 121. Since the motor positioning structure 1 is a component that appears in the tooling process, multiple outer rings 121 with different outer diameters can be configured on the tooling assembly line. When positioning the motor 2, an outer ring 121 that matches the size of the stator 21 of the motor 2 is selected to enter the tooling program. At this time, only one outer ring 121 that matches the size of the stator 21 needs to be selected and sleeved on the inner ring 11 to form the motor positioning structure 1. There is no need to set multiple outer rings 121 that are sleeved in sequence. After the outer ring 121 is sleeved on the inner ring 11 to form the motor positioning structure 1, the motor positioning structure 1 is set on the bearing seat 4, and then the stator 21 is set on the bearing seat 4 according to the positioning of the motor positioning structure 1. After the stator 21 is fixed to the bearing seat 4 by screws 221, the motor positioning structure 1 is taken out. In addition, when the outer ring assembly 12 includes only one outer ring 121 , magnetically connecting the outer ring assembly 12 and the inner ring 11 enables the outer ring assembly 12 and the inner ring 11 to be quickly connected and separated, thereby being more conducive to rapid replacement of the outer ring assembly 12 .

[0031] It should be noted that if Figure 2 , 3As shown, the stator 21 in the above-mentioned embodiment includes a mounting portion 210, and the stator 21 is fixed to the bearing seat 4 through the mounting portion 210. When the stator 21 is sleeved on the outer ring assembly 12, one end of the mounting portion 210 of the stator 21 abuts against the outer ring assembly 12. At this time, the stator 21 is positioned by abutting against the outer ring assembly 12 through one end of the mounting portion 210. A mounting hole 212 for a screw 211 is provided on the mounting portion 210. After the stator 21 is positioned, the stator 21 is fixed to the bearing seat 4 through the screw 211.

[0032] It should also be noted that the bearing seat 4 can be integrally formed with the outer cylinder 3. Of course, the bearing seat 4 can also be installed on the outer cylinder 3 after the outer cylinder 3 is formed. The above is not restrictive and can be set according to the needs of technical personnel in this field.

[0033] In addition, in order to ensure that the stator 21 can be smoothly mounted on the outer ring assembly 12, a chamfer can be set on the outer ring assembly, or the chamfer of the outer ring assembly 12 can be set to an arc shape. At this time, it can also avoid collisions between the stator 21 and the outer ring assembly 12 during contact.

[0034] The motor installation method of the present invention refers to Figure 2 , 3 The structure of the washing machine in Figure 4 As shown, the main steps of the motor installation method of the present invention specifically include the following steps:

[0035] Step S100: adjusting the outer diameter of the outer ring assembly 12 to match the size of the stator 21;

[0036] Step S200: sleeve the outer ring assembly 12 on the inner ring 11 to form the motor positioning structure 1, and fix the motor positioning structure 1 on the bearing seat 4;

[0037] Step S300: sleeve the stator 21 on the outer ring assembly 12 and fix the stator 21 on the bearing seat 4;

[0038] Step S400: taking out the motor positioning structure 1.

[0039] Before positioning and installing the motor 2, first select a suitable outer ring assembly 12 according to the size of the stator 21 of the motor 2. After the outer ring assembly 12 is selected, the outer ring assembly 12 is sleeved on the inner ring 11 to form a motor positioning structure 1. The motor positioning structure 1 is then set on the bearing seat 4. In order to ensure that the motor positioning structure 1 can be stably set on the bearing seat 4, the motor positioning structure 1 is fixed to the bearing seat 4. For example, the motor positioning structure 1 is set to be magnetically attracted to the bearing seat 4. Of course, the way the motor positioning structure 1 is fixed to the bearing seat 4 is not restrictive, and other ways can also be used to fix it to the bearing seat 4. After the motor positioning structure 1 is fixed to the bearing seat 4 Finally, the stator 21 of the motor 2 is sleeved on the motor positioning structure 1. After the motor 2 is positioned, the motor positioning structure 1 fixed on the bearing seat 4 is taken out. The above operation can ensure the reuse of the motor positioning structure 1. In the prior art, the motor 2 is positioned by a positioning ring, and the positioning ring needs to be molded separately and cannot be reused. Therefore, the positioning time and cost of the motor 2 are increased. The present invention positions the motor 2 by means of tooling and positions the motor 2 by setting the motor positioning structure 1. There is no need to use a positioning ring. After the positioning is completed, the motor positioning structure 1 is taken out, thereby realizing the reuse of the motor positioning structure 1 and further saving costs.

[0040] like Figure 5 As shown, the following is a first specific implementation of the motor installation method of the present invention, which specifically includes the following steps:

[0041] Step S100: adjusting the outer diameter of the outer ring assembly 12 to match the size of the stator 21;

[0042] Step S200: sleeve the outer ring assembly 12 on the inner ring 11 to form the motor positioning structure 1, and fix the motor positioning structure 1 on the bearing seat 4;

[0043] Step S300: sleeve the stator 21 on the outer ring assembly 12 and fix the stator 21 on the bearing seat 4;

[0044] Step S400: taking out the motor positioning structure 1;

[0045] Step S500 : after taking out the motor positioning structure 1 , fix the rotor 22 on the rotating shaft 41 .

[0046] After the motor positioning structure 1 is taken out, the rotor 22 is installed on the rotating shaft 41, so as to facilitate the subsequent driving effect of the motor 2 on the inner drum. It should be noted that the washing machine includes an outer drum 3 and an inner drum (not shown in the figure), the inner drum is installed in the outer drum 3, the bearing seat 4 is installed on the outer drum 3, the motor 2 is arranged on the bearing seat 4, the inner drum is fixedly connected with the rotating shaft 41, the rotating shaft 41 can pass through the outer drum 3 and the bearing seat 4, the rotating shaft 41 and the bearing seat 4 are rotatably connected, the rotor 22 of the motor 2 is fixed on the rotating shaft 41, the rotor 22 can drive the rotating shaft 41 to rotate, and then the rotating shaft 41 drives the inner drum to rotate, so as to ensure the inner drum to clean the clothes during the rotation process, because the motor 2 drives the inner drum, the working stability of the motor affects the working efficiency of the inner drum, therefore, accurately positioning the motor 2 can reduce the loss of the motor 2 and improve the working efficiency. And using the motor positioning structure 1 to position the motor 2 can not only ensure the accuracy of the positioning of the motor 2 but also save costs.

[0047] It should be noted that when the outer ring assembly 12 is configured to include multiple outer rings 121, and multiple outer rings 121 are sequentially arranged to form the outer ring assembly 12, adjusting the outer diameter of the outer ring assembly 12 to match the size of the stator 21 means adjusting the number of outer rings 121 according to the size of the stator 21 so that the outer diameter of the outer ring assembly 12 matches the size of the stator 21.

[0048] The size of the outer ring assembly 12 can be adjusted by sequentially installing multiple outer rings 121 as described above, and can also be achieved by replacing outer rings 121 with different outer diameters, that is, replacing outer rings 121 with different outer diameters according to different sizes of the stator 21 to form different motor positioning structures 1. Of course, it can also be achieved by directly adjusting the outer diameter of the outer ring assembly 12 by setting an adjustment assembly in the outer ring assembly 12. The above is not restrictive and can be set according to the needs of technical personnel in this field. Therefore, the above are all within the protection scope of the present invention.

[0049] In summary, the motor positioning structure 1 of the washing machine of the present invention includes an inner ring 11 and an outer ring assembly 12 sleeved on the inner ring 11, the bearing seat 4 is arranged on the outer cylinder 3, and the motor 2 is installed on the bearing seat 4. In order to ensure the stability and position accuracy of the motor 2 when it is installed on the bearing seat 4, before the motor 2 is installed, the motor positioning structure 1 is installed on the bearing seat 4, and then the stator 21 of the motor 2 is sleeved on the outer ring assembly 12 of the motor positioning structure 1, so that the outer ring assembly 12 can position the stator 21, and after the motor 2 is positioned, the motor 2 is fixed on the bearing seat 4, and then the motor positioning structure 1 is taken out so that the motor positioning structure 1 can be reused, thereby saving costs. In order to facilitate the removal of the motor positioning structure 1, a handle 113 can be set on the inner ring 11, and a supporting chassis 111 can be set on the inner ring 11. The supporting chassis 111 and / or the outer ring assembly 12 are magnetic, so that the supporting chassis 111 is magnetically connected to the outer ring assembly 12. The supporting chassis 111 is used to support the outer ring assembly 12 sleeved on the inner ring 11. When the outer ring assembly 12 includes multiple outer rings 121, an appropriate number of outer rings 121 are selected according to the size of the motor 2 and are sleeved in sequence to form the outer ring assembly 12 to achieve subsequent positioning of the motor 2. In order to prevent the outer ring assembly 12 from rotating on the inner ring 11, a groove 112 can be set on the inner ring 11, and a protrusion 122 can be correspondingly set on the outer ring assembly 12. When the outer ring assembly 12 is installed on the inner ring 11, the protrusion 122 is snapped into the groove 112. The support chassis 111 is set to be magnetic, and the support chassis 111 is magnetically connected to the bearing seat 4, which can ensure that the motor positioning structure 1 can be quickly removed from the bearing seat 4 after the stator 21 is positioned. In addition, since the motor positioning structure 1 is sleeved on the bearing seat 4, the accuracy of the motor positioning structure 1 in positioning the motor 2 can be ensured. Since the motor positioning structure 1 is a reusable component, in order to ensure that the motor positioning structure 1 can position different stators 21 while simplifying the structure of the motor positioning structure 1, the outer ring component 12 can be in the form of only one outer ring 121, and the outer diameter of the outer ring 121 matches the size of the stator 21 of the motor 2. When positioning the motor 2, it is only necessary to select an outer ring 121 that matches the size of the stator 21 and is sleeved on the inner ring 11 to form the motor positioning structure 1. There is no need to set a plurality of outer rings 121 that are sleeved in sequence. After the outer ring 121 is sleeved on the inner ring 11 to form the motor positioning structure 1, the motor positioning structure 1 is set on the bearing seat 4, and then the stator 21 is set on the bearing seat 4 according to the positioning of the motor positioning structure 1. After the stator 21 is fixed to the bearing seat 4 by screws 221, the motor positioning structure 1 is taken out.

[0050] It should be noted that the above-mentioned implementation mode is only used to illustrate the principle of the present invention and is not intended to limit the scope of protection of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above-mentioned structure so that the present invention can be applied to more specific application scenarios.
