[0037] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this application will not be described separately.

[0039] The term "comprises" or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed or that are inherent to such process, method, article, or apparatus. "Multiple" means greater than or equal to two.

[0040] The terms "some embodiments", "exemplarily" or "specifically" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application. In the present application, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0041] In the following description, the terms "upper", "lower", "outer" and "inner" used to describe the orientation refer to orientations in normal use.

[0042] In the related art, the clothes processing device is driven by a motor, but the noise of the motor is more prominent near certain frequencies. Therefore, the present application provides a technical solution to reduce the vibration noise of the motor, which effectively reduces the overall noise of the clothes processing device by suppressing the vibration noise of the motor.

[0043] The present application embodiment provides a clothes processing device, please refer to Figure 1 , Figure 6 and Figure 7 , including a clothes processing drum (not shown), a motor 10 and a dynamic vibration absorber 20.

[0044] The laundry processing device further comprises a housing, in which the laundry processing drum, the motor 10 and the dynamic vibration absorber 20 are all arranged. The housing is an appearance part of the laundry processing device, and provides installation space for components such as the laundry processing drum, the motor 10 and the dynamic vibration absorber 20.

[0045] The clothes processing drum has a clothes processing chamber, and the clothes processing chamber is used to accommodate clothes that need to be processed.

[0046] The motor 10 includes a motor housing 11, which is used to connect the components of the motor 10 together and protect the internal structure thereof. In some specific embodiments, the motor 10 also includes a power mechanism 12 disposed on the motor housing 11, and the power mechanism 12 is used to drive the laundry processing drum to rotate. It should be noted that the power mechanism 12 can be directly or indirectly connected to the laundry processing drum, that is, the power mechanism 12 can directly or indirectly drive the laundry processing drum to rotate.

[0047] It should be noted that the power mechanism 12 refers to a structure for transmitting torque. The power mechanism at least includes a motor shaft, and the motor shaft is used to output torque.

[0048] Please refer to Figure 1 , Figure 6 and Figure 7 The dynamic vibration absorber 20 includes a connecting member 21, an elastic support member 22 and a mass body 23, wherein the connecting member 21 is connected to the motor housing 11, and the elastic support member 22 connects the mass body 23 and the connecting member 21. In other words, the mass body 23 and the connecting member 21 are not directly connected, but are connected via the elastic support member 22.

[0049] In the laundry processing device of the embodiment of the present application, during use, the power mechanism of the motor 10 drives the laundry processing drum to rotate. When the motor 10 generates vibration, the dynamic vibration absorber 20 is forced to vibrate. Specifically, the vibration of the motor housing 11 is transmitted to the connecting member 21, and the connecting member 21 transmits the vibration to the elastic support member 22, and the elastic support member 22 drives the mass body 23 to vibrate.

[0050] In the clothes processing device of the embodiment of the present application, the motor 10 can be regarded as the main vibration system, and its vibration frequency can be regarded as the excitation frequency. When the excitation frequency is substantially the same as the natural frequency of the dynamic vibration absorber 20, the dynamic vibration absorber 20 has a good vibration absorption effect. Therefore, the dynamic vibration absorber 20 can have a good vibration absorption effect on the vibration with the excitation frequency near its natural frequency, and can effectively suppress the amplitude and vibration noise of the motor 10, thereby reducing the vibration noise of the clothes processing device; in addition, during installation, it is only necessary to connect the connector 21 to the motor housing 11, and the installation and disassembly procedures are relatively simple, saving time and effort.

[0051] It should be noted that, since the motor 10 is the main vibration system, its damping itself is relatively small. Therefore, even if the dynamic vibration absorber 20 of the embodiment of the present application has no other additional damping, it can still absorb the vibration of the motor 10 well.

[0052] The motor in the embodiment of the present application can be a fixed frequency motor or a variable frequency motor, which is not limited here.

[0053] It should be noted that for fixed-frequency motors, the noise of fixed-frequency motors is particularly prominent at certain specific frequencies. Therefore, for fixed-frequency motors, the embodiments of the present application can set the natural frequency of the dynamic vibration absorber to be near the specific frequency at which the noise of the fixed-frequency motor is prominent, which has a particularly obvious noise reduction effect on the fixed-frequency motor.

[0054] For some examples, please refer to Figure 1 , the mass body 23 is supported by the elastic support member 22. In other words, the mass body 23 is spatially positioned by the elastic support member 22, the elastic support member 22 needs to bear the weight of the mass body 23, and the elastic support member 22 needs to achieve a certain elastic deformation and have good structural strength to support the mass body 23. In this way, there is no need to set other structures on the motor housing 11 to support the mass body 23, which can simplify the installation structure between the dynamic vibration absorber 20 and the motor housing 11. The motor housing 11 can be changed with little structure or basically without structure change. On the basis of the existing motor housing 11, a dynamic vibration absorber 20 can be added at a relatively low cost, thereby improving the noise reduction performance of the clothing processing equipment and realizing the replacement of the clothing processing equipment.

[0055] In addition, the elastic support member 22 is helpful for realizing that the dynamic vibration absorber 20 has a lower natural frequency, for example, about 100 Hz, which is helpful for absorbing low-frequency vibrations.

[0056] For some examples, please refer to Figure 2 The mass body 23 has a receiving cavity 23A, and the elastic support member 22 is received in the receiving cavity 23A. This embodiment is conducive to reducing the space occupied by the dynamic vibration absorber 20. In addition, it can improve the reliability between the elastic support member 22 and the mass body 23, and the mass body 23 is not easy to separate from the elastic support member 22. Furthermore, the elastic support member 22 can elastically support the mass body 23 on the circumference surrounding the receiving cavity 23A, so that the mass body 23 can play a good vibration absorption role in any direction of vibration within the circumference surrounding the receiving cavity 23A.

[0057] It can be understood that, for example, the accommodating cavity 23A is cylindrical or any other centrally symmetrical shape, and any direction within the circumference surrounding the accommodating cavity 23A refers to any direction within a plane perpendicular to the central axis of the accommodating cavity 23A.

[0058] The specific shape of the mass body 23 is not limited.

[0059] For example, in some embodiments, please refer to Figure 1 and Figure 3The mass body 23 is roughly in the shape of a hollow cylinder, and the space inside the mass body 23 is the above-mentioned accommodating chamber 23A. Specifically, the mass body 23 is sleeved on the outer periphery of the elastic support member 22. The mass body 23 has a large mass, which not only plays the role of containing the elastic support member 22, but also cooperates with the elastic support member 22 to vibrate in various radial directions, and has a good vibration absorption effect. In addition, the structure is simple, which reduces the difficulty of manufacturing.

[0060] The material of the mass body 23 is not limited. For example, it can be a material with a high density such as metal or ceramic.

[0061] The mass body 23 may be an integrated structure, such as an integrated metal part or an integrated ceramic part. Of course, the mass body 23 may also be formed by connecting a plurality of independent parts to each other.

[0062] The specific shape of the elastic support member 22 is not limited.

[0063] For example, in some embodiments, please refer to Figure 3 The elastic support member 22 includes an inner ring portion 221, an outer ring portion 222 and a plurality of curved connecting portions 223. The outer ring portion 222 surrounds the outer circumference of the inner ring portion 221, and an annular area 32A is formed therebetween.

[0064] It should be noted that the inner ring portion 221 and the outer ring portion 222 may be coaxially arranged, that is, the axis of the inner ring portion 221 coincides with the axis of the outer ring portion 222. The inner ring portion 221 and the outer ring portion 222 may also be non-coaxially arranged, that is, the axis of the inner ring portion 221 and the axis of the outer ring portion 222 do not coincide. In the embodiment of the present application, the inner ring portion 221 and the outer ring portion 222 are coaxially arranged as an example for description.

[0065] The connecting member 21 is connected to the inner ring portion 221, and the mass body 23 is connected to the outer ring portion 222. The winding connection portion 223 is arranged in the annular area 32A. One end of the winding connection portion 223 is connected to the inner ring portion 221, and the other end is connected to the outer ring portion 222. In other words, the inner ring portion 221 and the outer ring portion 222 are not in contact, and the two are connected by the winding connection portion 223.

[0066] The meandering connection portion 223 has a length component along the circumferential direction so as to generate elastic deformation along the radial direction when vibrating. In this embodiment, the elastic support member 22 realizes elastic deformation by means of the meandering connection portion 223 .

[0067] It should be noted that, during vibration, the flexural connection portion 223 undergoes elastic deformation, thereby causing the outer ring portion 222 and the inner ring portion 221 to undergo radial relative displacement, thereby achieving vibration.

[0068] The structural form of the inner ring portion 221 facilitates the connection between the inner ring portion 221 and the connecting member 21. Specifically, the connecting member 21 can be inserted into the inner ring portion 221, so that the connection is convenient and the two can have a larger contact area, thereby improving the connection reliability of the two. The connection method between the inner ring portion 221 and the connecting member 21 is not limited, for example, bonding, interference fit, screw connection, etc.

[0069] The structure of the outer ring 222 facilitates the connection between the outer ring 222 and the mass body 23. Specifically, the mass body 23 can be sleeved on the outer ring 222. In this way, the connection is convenient, and the two can have a larger contact area, thereby improving the connection reliability of the two. The connection method between the outer ring 222 and the mass body 23 is not limited, for example, bonding, interference fit, screw connection, etc.

[0070] In this embodiment, the structural form of the elastic support member 22 enables the curved connection portion 223 to effectively support the outer ring portion 222 and the mass body 23 and achieve better elastic deformation.

[0071] It should be noted that, in this embodiment, during vibration, the vibration displacement directions of the outer ring portion 222 and the mass body 23 relative to the connecting member 21 are mainly along various directions of the plane perpendicular to the axial direction of the outer ring portion 222, and the vibration displacement along the axial direction is very small, or even almost non-existent.

[0072] The winding method of the winding connection portion 223 is not limited.

[0073] For some examples, please refer to Figure 3 A single winding connection portion 223 is wound back and forth along the circumferential direction, and a plurality of winding connection portions 223 are arranged at intervals along the circumferential direction. Figure 3 The illustrated embodiment has two winding connection portions 223 , but it is understandable that the number of the winding connection portions 223 may be more than two.

[0074] The circumferential reciprocating winding means, for example, starting from the connection between the winding connection portion 223 and the inner ring portion 221, extending along a first circumferential direction for a distance, turning radially outward, and then extending along a second circumferential direction, wherein the first direction and the second direction are opposite. Depending on the number of windings of the winding connection portion 223, the winding connection portion 223 can be extended alternately in the first direction and the second direction.

[0075] In some embodiments, the center angle of the curved connection portion 223 is not less than 90°. It is understandable that the center angle of the curved connection portion 223 is the center angle defined by the entire area of ​​the curved connection portion 223 relative to the center of the inner circle 221, with the center of the inner circle 221 as the reference.

[0076] In this embodiment, the meandering connection portion 223 has a relatively long extension length along the circumferential direction, so that the meandering connection portion 223 is more likely to undergo elastic deformation.

[0077] For other embodiments, please refer to Figure 4 and Figure 5 A single winding connection part 223 extends in a spiral shape, and a plurality of winding connection parts 223 are arranged radially. All the winding connection parts 223 provide good radial support for the mass body 23 and can also have good elastic deformation; in addition, it is also easy to manufacture.

[0078] In some embodiments, the spiral extension angle of a single winding connection portion 223 is not less than 90°, so that the spiral winding connection portion 223 is more likely to undergo elastic deformation.

[0079] It should be noted that the above-mentioned “angle of spiral extension” refers to the central angle defined by the entire area where the curved connecting portion 223 is located relative to the center of the inner circle portion 221 , with the center of the inner circle portion 221 as a reference.

[0080] For some examples, please refer to Figure 1 and Figure 8 One end of the connecting member 21 is passed through the inner ring portion 221, and the other end is connected to the motor housing 11. On the one hand, the vibration direction of the dynamic vibration absorber 20 is mainly along the radial direction of the inner ring portion 221. Since the connecting member 21 is passed through the inner ring portion 221, the inner ring portion 221 will not be separated from the connecting member 21 in the radial direction, which can ensure the vibration absorption reliability of the dynamic vibration absorber 20; in addition, it is also convenient to connect the connecting member 21 with the inner ring portion 221.

[0081] For some examples, please refer to Figure 1 or Figure 4 The elastic support member 22 is an integrated plastic member. In this way, the elastic support member 22 has good structural strength, can reliably support the mass body 23, and can also produce elastic deformation. In addition, the structure is reliable and not easy to fail.

[0082] The specific material of the plastic is not limited, such as ABS (Acrylonitrile Butadiene Styrene) plastic, POM (Polyoxymethylene) plastic or PA (Polyamide) plastic, etc. The above plastics have good rigidity, and the elastic support member 22 formed also has sufficient elasticity.

[0083] It should be noted that the motor 10, as the main vibration system, has different excitation frequencies at different speeds. In the related art, when the excitation frequency of the motor is around 100 Hz, the noise radiated by the motor is abnormally obvious and louder than the noise at other excitation frequencies. Therefore, it is necessary to weaken the vibration peak of this frequency.

[0084] To this end, in some embodiments, the natural frequency of the dynamic vibration absorber 20 is 80 Hz to 120 Hz (Hertz). For example, 80 Hz, 90 Hz, 100 Hz, 110 Hz or 120 Hz. In this embodiment, the natural frequency of the dynamic vibration absorber 20 is designed to be 80 Hz to 120 Hz, so that it is near the frequency band where the vibration noise of the motor is more obvious, which can effectively reduce the vibration peak noise.

[0085] The natural frequency specifically refers to the natural frequency of the first-order vibration mode of the vibration system composed of the mass body 23, the elastic support member 22, and the connecting member 21, which is related to the mass of the mass body 23, the stiffness of the elastic support member 22, and the like.

[0086] Specifically, the natural frequency of the dynamic vibration absorber is f0, the equivalent stiffness of the elastic support member 22 is K, the equivalent mass of the mass body 23 is M, and the relationship f0≈(K / M) 1 / 2 When the excitation frequency to be suppressed is equal to f0, the amplitude of the mass body 23 and the elastic support member 22 reaches the maximum, and the vibration energy absorbed is the largest.

[0087] For some examples, please refer to Figures 6 to 9 , the opposite ends of the motor shaft 121 along the axial direction protrude from the opposite sides of the motor housing 11. The laundry processing device includes two support bases 30, and the two ends of the motor shaft 121 are respectively supported on the corresponding support bases 30, so that the motor housing 11 is suspended. In other words, the motor housing 11 is not directly fixed to the support base 30 or other fixed structures.

[0088] Since the motor housing 11 is suspended in the air, the motor housing 11 will vibrate greatly, and the vibration energy of the motor 10 is more concentrated in the form of vibration displacement of the motor housing 11. In the embodiment of the present application, the dynamic vibration absorber 20 is connected to the motor housing 11, which can better reduce the vibration of the motor 10.

[0089] For example, please refer to Figure 6 and Figure 7 The clothing processing device includes a base 40, a clothing processing drum is located above the base, and the bottom end of the support base 30 is connected to the base.

[0090] For some examples, please refer to Figures 6 to 8 , the connecting member 21 is parallel to the motor shaft 121. The main vibration direction of the motor 10 is along the radial direction of the motor shaft 121, and the connecting member 21 is arranged parallel to the motor shaft 121. Correspondingly, the dynamic vibration absorber 20 is also forced to vibrate in the radial direction of the motor shaft to effectively absorb the vibration of the motor 10.

[0091] In some embodiments, the motor shaft 121 may be coaxially connected to the laundry processing drum to drive the laundry processing drum to rotate.

[0092] For other embodiments, please refer to Fig. 9 The power mechanism 12 also includes a transmission shaft 122, and the motor shaft 121 is used to drive the transmission shaft 122 to rotate. For example, power transmission can be achieved between the motor shaft 121 and the transmission shaft 122 through gear transmission, chain transmission, belt transmission, etc.

[0093] The laundry processing device further comprises a conveyor belt 50, which is wound around the transmission shaft 122 and the laundry processing drum to drive the laundry processing drum to rotate. In this way, the laundry processing drum can be driven to rotate at a relatively low speed.

[0094] Exemplarily, the clothes processing device further includes an elastic member 60, one end of which is connected to the motor housing 11. The other end of the elastic member 60 can be directly or indirectly connected to the base, or other structures, as long as it can provide force support for the elastic member 60. It can be understood that since the motor housing 11 is suspended, the conveyor belt 50 will generate a first torque on the motor housing 11, and the elastic force applied by the elastic member 60 to the motor housing 11 will generate a second torque on the motor housing 11, wherein the directions of the first torque and the second torque are opposite.

[0095] It should be noted that due to the characteristics of belt transmission, the rotation of the clothing processing drum or the change in the center of mass position due to the storage of the clothes to be processed inside the clothing processing drum, the clothing processing drum may rotate eccentrically. Therefore, the suspended setting of the motor housing 11 allows the motor housing 11 to adjust the position of the transmission shaft 122 by swinging, and the first torque and the second torque are in a dynamic equilibrium state, thereby allowing the conveyor belt 50 and the clothing processing drum to always be in a suitable tension state, thereby reducing the chance of slipping and the chance of the conveyor belt 50 being stuck due to being too tensioned.

[0096] The specific form of the elastic member 60 is not limited, for example, it can be a tension spring, a rubber band, etc. In the embodiment of the present application, the elastic member 60 is a tension spring.

[0097] For some examples, please refer to Figure 8 and Fig. 9 The motor housing 11 includes a housing body 111 and an extension frame 112. Two ends of the motor shaft 121 protrude from opposite sides of the housing body 111. The housing body 111 contains components such as the stator and the rotor of the motor.

[0098] The extension frame 112 may be a separate structural member, which is fixed to the shell body 111 by bolts. Of course, the extension frame 112 may also be an integrated structure with a part of the shell body 111.

[0099] The extension frame 112 protrudes from the outer peripheral surface of the shell body 111, and the transmission shaft 122 and the dynamic vibration absorber 20 are both disposed on the extension frame 112. Exemplarily, one end of the elastic member 60 is connected to the extension frame 112.

[0100] It should be noted that a pulley or other structure may be provided on the transmission shaft 122 , and the conveyor belt is wound around the pulley.

[0101] It is understandable that both the elastic member 60 and the transmission shaft 122 can be connected to the extension frame, and the extension frame 112 is subjected to both the first torque and the second torque. Therefore, the vibration amplitude of the extension frame in the related art is relatively obvious. In the embodiment of the present application, the dynamic vibration absorber 20 is arranged on the extension frame 112 to suppress the vibration generated by the extension frame 112 being subjected to the above torque, which can significantly reduce the vibration amplitude and vibration noise of the extension frame 112, thereby suppressing the vibration amplitude and vibration noise of the motor assembly.

[0102] Exemplarily, the connecting member 21 of the dynamic vibration absorber 20 is parallel to the axial direction of the transmission shaft 122 and is arranged on the extension frame 112, so that the displacement direction and displacement magnitude of the connecting member 21 are relatively close to the displacement direction and displacement magnitude of the transmission shaft 122, and the vibration absorption effect of the dynamic vibration absorber 20 is better. In some embodiments, the connecting member 21 and the transmission shaft 122 are coaxially arranged.

[0103] It should be noted that the connecting member 21 is not linked to the transmission shaft 122 , the two are not connected, and the connecting member 21 will not move with the transmission shaft 122 .

[0104] For some examples, please refer to Figures 6 to 8 The transmission shaft 122 and the dynamic vibration absorber 20 are arranged on opposite sides of the extension frame 112 along the axial direction of the transmission shaft 122. In this way, interference between the dynamic vibration absorber 20 and the power mechanism 12 can be avoided, and the space on the side of the extension frame 112 away from the transmission shaft 122 can be fully utilized, making the structure compact.

[0105] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
