[0045] Reference Figures 1-8 , which is an embodiment of the motor fixing structure of the utility model, specifically relates to a motor fixing component of a clothing processing device, which is intended to isolate the vibration of the motor itself in the clothing processing device from being transmitted to components such as the washing tub, so as to reduce the overall noise of the clothing processing device.
[0046] See also Figure 2The motor 200 fixing structure includes a motor 200 and a fixing assembly 300 .
[0047] The motor 200 housing is provided with a first support portion 210, which is provided with a first mounting hole 211. The first support portion 210 protrudes to one side at a certain angle toward the front and outside of the motor 200 housing. The outer end of the first support portion 210 is a cylindrical structure, and the first mounting hole 211 is provided through the cylindrical structure of the first support portion 210.
[0048] The fixing assembly 300 is used to fix the motor 200 on the mounting component.
[0049] In some embodiments of the present application, the mounting component is the outer drum 100 of the laundry processing device. The output shaft on the front side of the motor 200 is connected to the inner drum through a belt to drive the inner drum to rotate.
[0050] See also Figure 2 and Figure 3 Specifically, the fixing assembly 300 includes a first shock absorber 310 , a threaded connection 320 and a gasket 330 .
[0051] like Figure 5 As shown, the first shock absorber 310 includes a first sleeve portion 311, a first flange portion 312 and a second flange portion 313 provided at both ends of the first sleeve portion 311. The first shock absorber 310 has a central hole that passes through the sleeve portion, the first flange portion 312 and the second flange portion 313 along its axial direction.
[0052] The first shock absorber 310 is installed in the first mounting hole 211 , that is, the first sleeve portion 311 is sleeved in the first mounting hole 211 , and the first flange portion 312 and the second flange portion 313 respectively abut against the first support portions 210 at both ends of the mounting hole.
[0053] The first shock absorber 310 can isolate the motor 200 from the outer cylinder 100 , weaken the vibration transmitted from the motor 200 to the outer cylinder 100 , and play a role in vibration isolation, thereby reducing equipment noise.
[0054] The material of the first shock absorber 310 can be selected according to actual needs as long as it can achieve the expected vibration isolation and noise reduction effect. For example, the first shock absorber 310 is rubber or thermoplastic elastomer.
[0055] The threaded connector 320 includes a shaft with a fixed head portion, wherein the shaft portion is provided with external threads. When the motor 200 is assembled, the shaft portion of the threaded connector 320 passes through the center hole of the first shock absorber 310 and is fixedly connected to the threaded hole in the outer cylinder 100. The threaded connector 320 can be a screw, bolt, or threaded rod.
[0056] The washer 330 is sleeved on the rod of the threaded connector 320 and is located between the head of the threaded connector 320 and the first flange portion 312 , respectively abutting against the head of the threaded connector 320 and the first flange portion 312 .
[0057] The installation of gasket 330 ensures that motor 200 remains securely fixed, preventing it from tilting under belt tension. This significantly reduces vibration and noise while ensuring normal operation of the equipment. Furthermore, under appropriate tightening torque, gasket 330 uniformly compresses first damper 310, evenly distributing the torque generated by motor 200's vibration. This reduces eccentric vibration and extends the motor's service life.
[0058] The material of the gasket 330 can be selected according to actual needs so as to achieve the desired fastening effect. For example, the gasket 330 can be a metal gasket. In other embodiments, the gasket 330 can also be fixedly connected to the head of the threaded connector 320, that is, the gasket 330 and the threaded connector 320 are a fixedly connected integral structure.
[0059] The above-mentioned motor 200 fixing structure, by providing the first shock absorber 310, can completely isolate the motor 200 from the mounting component, thereby weakening the vibration transmitted to the mounting component by the motor 200. At the same time, the first shock absorber 310 isolates the threaded connection 320, blocking the transmission path of vibration through the threaded connection 320, thereby improving the overall shock absorption performance.
[0060] In some embodiments of the present application, the outer side wall of the first sleeve portion 311 of the first shock absorber 310 is provided with a first protrusion 3111 , that is, the contact surface between the first sleeve portion 311 and the inner wall of the first mounting hole 211 is provided with a first protrusion 3111 .
[0061] The first protrusion 3111 contacts the first support portion 210 of the motor 200. Since there is a gap between two adjacent first protrusions 3111, the contact area between the first shock absorber 310 and the first support portion 210 is reduced, effectively reducing the vibration transmitted from the motor 200 to the outer drum 100, thereby further reducing the overall noise of the clothing processing equipment.
[0062] The specific structure and size of the first protrusion 3111 can be selected according to actual needs.
[0063] For example, in some embodiments, Figure 5 As shown, the first protrusion 3111 is annular. In other embodiments, the first protrusion 3111 may be in the shape of an elongated strip extending along the axial direction of the first sleeve portion 311 .
[0064] The number of the first protrusions 3111 is at least two, and the specific number is not limited. For example, the number of the first protrusions 3111 is 6. The first protrusions 3111 are evenly distributed in an annular shape along the circumference of the first shock absorber 310 .
[0065] In some embodiments of the present application, a second protrusion 3131 is provided on the outer end surface of the second flange portion 313 of the first shock absorber 310 .
[0066] The second protrusions 3131 are in contact with the outer drum 100. Since there is a gap between two adjacent second protrusions 3131, the contact area between the first shock absorber 310 and the outer drum 100 is reduced, effectively reducing the vibration transmitted from the motor 200 to the outer drum 100, thereby further reducing the overall noise of the clothing processing equipment.
[0067] The specific structure and size of the second protrusion 3131 can be selected according to actual needs.
[0068] For example, in some embodiments, Figure 5 As shown, the second protrusion 3131 is fan-shaped.
[0069] In other embodiments, Figure 6 As shown, the second protrusion 3131 is rectangular, or the second protrusion 3131 is hemispherical, etc.
[0070] The number of the second protrusions 3131 is at least two, but is not limited to a specific number. For example, the number of the second protrusions 3131 is 6. The second protrusions 3131 are evenly distributed along the circumference of the first shock absorber 310 and are coaxially arranged with the first shock absorber 310 to improve the stability of the fit.
[0071] In other embodiments of the present application, a first groove may be provided on the outer sidewall of the first sleeve portion 311, and a second groove may be provided on the outer end surface of the second flange portion 313, thereby reducing the contact area between the first shock absorber 310 and the motor 200 and the outer cylinder 100. The shape, size, and number of the first and second grooves may be set according to actual needs.
[0072] In order to improve the fixing stability of the motor 200, in some embodiments of the present application, the housing of the motor 200 may be provided with two or more first support portions 210, and the motor 200 may be fixed to the outer cylinder 100 via a plurality of fixing assemblies 300.
[0073] In order to improve the stability of the motor 200, in some embodiments of the present application, such as Figure 2As shown, the housing of the motor 200 is provided with a second support portion 220, and a second mounting hole 221 is formed in the second support portion 220. The second support portion 220 is formed to protrude toward the rear side of the housing of the motor 200, and the rear end of the second support portion 220 is a cylindrical structure. The second mounting hole 221 of the second support portion 220 is provided through the cylindrical structure of the second support portion 220.
[0074] The second supporting portion 220 abuts against the mounting component and mainly plays a supporting and positioning role.
[0075] A second shock absorber 340 is sleeved within the second mounting hole 221. The second shock absorber 340 specifically comprises a second sleeve portion 341 and a third flange portion 342 disposed at one end of the second sleeve portion 341. The second sleeve portion 341 sleeves within the second mounting hole 221, and the third flange portion 342 is configured to support and abut between the second support portion 220 and the mounting component.
[0076] The second shock absorber 340 can isolate the motor 200 from the outer cylinder 100 , weaken the vibration transmitted from the motor 200 to the outer cylinder 100 , and play a role in vibration isolation, thereby reducing equipment noise.
[0077] The material of the second shock absorber 340 can be selected according to actual needs as long as it can achieve the expected vibration isolation and noise reduction effect. For example, the second shock absorber 340 is rubber or thermoplastic elastomer.
[0078] In some embodiments of the present application, Figure 7 As shown, a third protrusion 3411 is provided on the outer wall of the second sleeve portion 341. The third protrusion 3411 contacts the second support portion 220 of the motor 200. Since there is a gap between two adjacent third protrusions 3411, the contact area between the second shock absorber 340 and the second support portion 220 is reduced, effectively reducing the vibration transmitted from the motor 200 to the outer drum 100, thereby further reducing the overall noise of the laundry processing apparatus.
[0079] The specific structure and size of the third protrusion 3411 can be selected according to actual needs. For example, in some embodiments, the third protrusion 3411 is annular. In other embodiments, Figure 7 As shown, the third protrusion 3411 may be in the shape of a long strip extending along the axial direction of the second sleeve portion 341 .
[0080] In some embodiments of the present application, a fourth protrusion 3421 is provided on the outer end surface of the third flange portion 342 .
[0081] The fourth protrusion 3421 contacts the outer drum 100. Since there is a gap between two adjacent fourth protrusions 3421, the contact area between the second shock absorber 340 and the outer drum 100 is reduced, effectively reducing the vibration transmitted from the motor 200 to the outer drum 100, thereby further reducing the overall noise of the clothing processing equipment.
[0082] The specific structure and size of the fourth protrusion 3421 can be selected according to actual needs. For example, in some embodiments, Figure 7 As shown, the fourth protrusion 3421 is fan-shaped. In other embodiments, such as Figure 8 As shown, the fourth protrusion 3421 is rectangular, or the fourth protrusion 3421 is hemispherical, etc.
[0083] The number of the fourth protrusions 3421 is at least two, but is not limited to a specific number. For example, the number of the fourth protrusions 3421 is 6. The fourth protrusions 3421 are evenly distributed along the circumference of the first shock absorber 310 and are coaxially arranged with the second shock absorber 340 to improve the stability of the fit.
[0084] In other embodiments of the present application, a third groove may be provided on the outer sidewall of the second sleeve portion 341, and a fourth groove may be provided on the outer end surface of the third flange portion 342, thereby reducing the contact area between the second shock absorber 340 and the motor 200 and the outer cylinder 100. The shape, size, and number of the third and fourth grooves may be set according to actual needs.
[0085] In some embodiments of the present application, the first protrusion 3111 and the third protrusion 3411 provided on the first shock absorber 310 and the second shock absorber 340 may have the same or different specific structures; the second protrusion 3131 and the fourth protrusion 3421 provided on the first shock absorber 310 and the second shock absorber 340 may have the same or different specific structures.
[0086] In some embodiments of the present application, in order to ensure a reliable assembly effect, the outermost diameter of the gasket 330 is preferably greater than or equal to the outermost diameter of the first flange portion 312 of the first shock absorber 310 .
[0087] The present application also provides a clothing processing device, which can be a washing machine, a shoe washer, a clothes dryer, etc. The clothing processing device includes an outer drum 100, an inner drum, and the above-mentioned motor 200 fixing structure, wherein the mounting component is the outer drum 100, that is, the motor 200 is fixed to the outer drum 100, and is used to drive the inner drum to rotate.
[0088] Specifically, if Figure 2As shown, a cylindrical fixing portion 110 is provided on the outer cylinder 100 , a screw hole is opened on the cylindrical fixing portion 110 , and the cylindrical fixing portion 110 passes through the center hole of the first shock absorber 310 and is threadedly fixedly connected to the threaded connector 320 .
[0089] The outer cylinder 100 is further provided with a cylindrical support positioning portion 120 , which passes through the center hole of the second shock absorber 340 . The second support portion 220 of the motor 200 is positioned and supported on the cylindrical support positioning portion 120 on the outer cylinder 100 through the second shock absorber 340 .
[0090] The above-mentioned clothing processing device completely isolates the motor 200 from the outer drum 100 by providing a first shock absorber 310 and a second shock absorber 340. The first shock absorber 310 and the second shock absorber 340 provide a buffer to weaken the vibration transmitted to the equipment by the motor 200, play a vibration isolation role, and effectively isolate the vibration of the motor 200 and the propagation of solid-borne sound, thereby reducing the noise of the entire machine.
[0091] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents.
