[0002] Clothes processing equipment is a common household appliance. At present, consumers have higher and higher requirements for clothing processing equipment, especially its noise problem, which seriously affects consumers' user experience.

In the prior art, the motors of clothing processing equipment mainly include variable frequency motors and fixed frequency motors. Among them, fixed frequency motors do not require frequency conversion boards, so they have relatively low prices and have attracted much attention from consumers. However, the problem that comes with it is that certain specific frequencies of fixed frequency motors, such as 100Hz frequency motors, have large vibration amplitudes when working, and generate large noise, resulting in large overall shaking amplitudes of the clothing processing equipment equipped with the motor and large noise of the whole machine. Therefore, it is necessary to equip the motor with a vibration reduction and noise reduction structure to reduce the vibration and noise of the motor and improve the user experience of the clothing processing equipment.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] Clothes processing equipment is a common household appliance. At present, consumers have higher and higher requirements for clothing processing equipment, especially its noise problem, which seriously affects consumers' user experience. The noise of clothing processing equipment is mainly caused by the vibration generated by the internal motor of the clothing processing equipment when it is working. In the prior art, the motors of clothing processing equipment mainly include variable frequency motors and fixed frequency motors. Among them, fixed frequency motors do not require frequency conversion boards, so they have relatively low prices and have attracted much attention from consumers. However, the problem that comes with it is that certain specific frequencies of fixed frequency motors, such as 100Hz frequency motors, have large vibration amplitudes when working, and generate large noise, resulting in large overall shaking amplitudes of the clothing processing equipment equipped with the motor and large noise of the whole machine. Therefore, it is necessary to equip the motor with a vibration reduction and noise reduction structure to reduce the vibration and noise of the motor and improve the user experience of the clothing processing equipment.

[0034] Reference below Figure 1-Figure 4A motor front cover assembly according to an embodiment of the utility model is described.

[0035] According to the utility model, the motor front cover assembly 1 includes a front cover body 11, a vibration-damping shell 12, a vibration-damping member 13 and a swinging member 14. The vibration-damping shell 12 is arranged on the front cover body 11; the vibration-damping member 13 is deformably arranged in the vibration-damping shell 12 and is connected to the inner wall of the vibration-damping shell 12; the swinging member 14 is connected to the vibration-damping member 13 and is swingably arranged in the vibration-damping shell 12. The swinging member 14 can selectively swing in the vibration-damping shell 12 to buffer the vibration generated by the front cover body 11.

[0036] According to the motor front cover assembly 1 of the utility model, a front cover body 11 is provided, and the front cover body 11 can be covered on at least part of the outer periphery of the motor to protect the motor, and a vibration-damping shell 12 is provided on the front cover body 11, and a vibration-damping member 13 and a swinging member 14 are provided in the vibration-damping shell 12. Specifically, the vibration-damping member 13 is deformably connected to the inner wall of the vibration-damping shell 12, and the swinging member 14 is connected to the vibration-damping member 13 and can selectively swing in the vibration-damping shell 12. When the motor generates vibration during operation, the vibration will be transmitted to the front cover body 11, and the front cover body 11 will transmit the vibration to the vibration-damping shell 12. When the vibration-damping shell 12 is affected by the vibration, the vibration-damping member 13 can be deformed to buffer the vibration of the vibration-damping shell 12, and at the same time, the swinging member 14 can swing in the vibration-damping shell 12 to offset part of the vibration. The front cover assembly can achieve vibration reduction in two ways, namely, deformation energy absorption and swing energy absorption, by cooperating with the vibration damping member 13 and the swinging member 14. The vibration reduction effect is good and can reduce the influence of the vibration generated by the motor on the front cover body 11, thereby reducing the influence of the motor vibration on the equipment or other structures connected to the motor, thereby reducing the vibration and noise of the entire equipment, which can effectively improve the user experience.

[0037] According to one embodiment of the utility model, the swing member 14 includes a swing shell 141 and a counterweight 142. The swing shell 141 is swingably disposed on the vibration-damping shell 12 and connected to the vibration-damping member 13. A accommodating cavity is formed in the swing shell 141; the counterweight 142 is accommodated in the swing shell 141.

[0038] Since the swing member 14 is swingably arranged in the vibration-damping housing 12, the structure of the swing member 14 will affect the vibration-damping effect of the swing member 14. Specifically, the swing member 14 is provided with a swing housing 141 and a counterweight 142. The swing housing 141 is connected to the vibration-damping member 13 and is swingably arranged in the vibration-damping housing 12. A cavity is formed in the swing housing 141, and the counterweight 142 can be assembled into the cavity of the swing housing 141. When the vibration-damping housing 12 is vibrated, the swing member 14 can swing in the vibration-damping housing 12 to offset a part of the vibration, thereby realizing the vibration-damping function. The arrangement of the counterweight 142 and the swing housing 141 makes the weight of the swing member 14 controllable. It can be simply understood that, when facing different motors, counterweights 142 of different masses can be used, so that the swing member 14 has different vibration-damping effects, and then the swing member 14 can buffer and reduce vibration of various types of motors, thereby improving the vibration-damping effect and adaptability of the swing member 14.

[0039] According to one embodiment of the present invention, the natural frequency of the motor is f 0 , the resonance frequency of the vibration-damping housing 12, the vibration-damping member 13 and the swinging member 14 is f, the stiffness of the vibration-damping member 13 is K, the mass of the swinging member 14 is M, and they satisfy: f 0 =f≈(K / M) 1 / 2 .

[0040] The vibration damping member 13 and the swing member 14 have different buffering and vibration reduction effects for different motors. It can be understood that the vibration reduction effects of the vibration damping member 13 and the swing member 14 are related to the natural frequency of the motor. Specifically, when the resonance frequency of the vibration damping housing 12, the vibration damping member 13 and the swing member 14 is f, the stiffness of the vibration damping member 13 is K, and the mass of the swing member 14 is M, the resonance frequency of the system formed by the vibration damping housing 12, the vibration damping member 13 and the swing member 14 can be expressed as f≈(K / M) 1 / 2 At this time, when the natural frequency of the motor is 0 When it is equal to the resonance frequency f of the vibration-damping housing 12, the vibration-damping member 13 and the swinging member 14, the vibration-damping system formed by the vibration-damping housing 12, the vibration-damping member 13 and the swinging member 14 has the best vibration-damping effect on the motor, the displacement of the swinging member 14 is the largest, and the vibration energy absorbed is the most.

[0041] For example, when the natural frequency of the motor is 100 Hz, the vibration generated by the 100 Hz motor will amplify the vibration noise of 100 Hz frequency when it is transmitted to other structures through the motor's secondary wheel and belt. When the 100 Hz vibration reaches the vibration damping housing 12, the vibration damping system formed by the vibration damping housing 12, the vibration damping member 13 and the swing member 14 will resonate, and the vibration displacement will reach a peak value, thereby effectively absorbing the vibration energy of 100 Hz frequency, so that the noise ultimately transmitted by the motor as a whole is reduced.

[0042] When the natural frequency of the motor is other values, the resonant frequency of the system formed by the vibration-damping shell 12, the vibration-damping member 13 and the swinging member 14 can be adjusted to be consistent with the natural frequency of the motor by changing the weight of the counterweight 142 and changing the stiffness of the vibration-damping member 13, so that the vibration-damping effect of the vibration-damping shell 12, the vibration-damping member 13 and the swinging member 14 is in the best state.

[0043] According to an embodiment of the present invention, the swing displacement of the swing member 14 in the first direction is d 1 , and satisfy: -1mm≤d 1 ≤1mm; the swing displacement of the swing member 14 in the second direction is d 2 , and satisfy: -2mm≤d 2 ≤2mm; wherein the first direction is orthogonal to the second direction.

[0044] Since the swing member 14 realizes buffering and vibration reduction by swinging, the swing amplitude and swing angle of the swing member 14 will affect the vibration reduction effect of the swing member 14. Specifically, the swing member 14 can swing in the first direction and the second direction, the first direction and the second direction are orthogonal to each other, and the plane where the first direction and the second direction are located can be perpendicular to the direction of the torque transmitted by the motor. It can also be simply understood that when the motor front cover assembly 1 is assembled with the motor, after the vibration of the motor is transmitted to the motor front cover, the direction of the vibration is in a plane perpendicular to the direction of the motor output torque, and the first direction and the second direction orthogonal to each other are respectively orthogonal to the direction of the motor output torque, that is, the first direction and the second direction are in the plane of the motor front cover vibration transmission. At this time, the swinging of the swing member 14 in the first direction and the second direction can effectively improve the swinging energy absorption effect of the swing member 14.

[0045] In actual processing, the swing displacement of the swing member 14 in the first direction is d 1 , and satisfy: -1mm≤d 1 ≤1mm; the swing displacement of the swing member 14 in the second direction is d 2 , and satisfy: -2mm≤d 2 ≤2mm; Since the vibration-damping housing 12 is directly disposed on the front cover body 11, such as Figure 1 to Figure 3 As shown, the mating surface of the vibration-damping housing 12 and the front cover body 11 is in the first direction. Therefore, compared with the first direction, the vibration amplitude in the second direction is larger, and d 2 Greater than d 1 The swing member 14 can be made to swing to the maximum extent to absorb energy according to the vibration direction within a limited space, thereby improving the vibration reduction effect of the swing member 14. 1 Satisfy -1mm≤d 1 ≤1mm can reduce the vibration of the swing member 14 in the first direction, wherein, if d 1Too large, that is, the swing amplitude of the swing member 14 is too large, which will cause new vibration. On the contrary, if d 1 Too small means that the swing amplitude of the swing member 14 is too small, resulting in a reduced vibration reduction effect of the swing member 14; similarly, d 2 Satisfy -2mm≤d 2 ≤2mm can reduce the vibration of the swing member 14 in the second direction, wherein, if d 2 Too large, that is, the swing amplitude of the swing member 14 is too large, which will cause new vibration. On the contrary, if d 2 Too small means that the swing amplitude of the swing member 14 is too small, resulting in reduced vibration reduction effect of the swing member 14.

[0046] According to an embodiment of the utility model, the length of the vibration damper 13 is L, and satisfies: 25mm≤L≤75mm. Specifically, due to the limited space in the vibration damper housing 12, the length of the vibration damper 13 will affect the assembly of the vibration damper 13. In actual processing, the length of the vibration damper 13 can be represented by L, and satisfies: 25mm≤L≤75mm. When the length of the vibration damper 13 is too short, the deformation of the vibration damper 13 in the vibration damper housing 12 is small, and the shock absorption effect is poor; when the length of the vibration damper 13 is too long, the vibration damper 13 occupies a large space and is difficult to assemble. Therefore, the length L of the vibration damper 13 can be selected as any value in the range of 25mm to 75mm, and the specific value can be selected according to the actual motor power and other conditions.

[0047] In some embodiments, the vibration damper 13 can be assembled into the vibration damping shell by bending. The bent vibration damper 13 presents a spring-like structure, which can increase the deformation of the vibration damper 13 and thereby improve the vibration reduction and energy absorption effect of the vibration damper 13.

[0048] According to one embodiment of the present invention, the thickness of the vibration damping member 13 is d 3 , and meet: 0.5mm≤d 3 ≤1.5mm. Similar to the above embodiment, when the thickness of the vibration damper 13 is too small, the vibration damper 13 itself has low structural strength, and the vibration damper 13 is easily damaged when the vibration is large; when the thickness of the vibration damper 13 is too large, the structural strength of the vibration damper 13 is high, and it is difficult to deform, and it is impossible to effectively reduce vibration and absorb energy by deformation. Therefore, the thickness d of the vibration damper 13 is 3 It can be in the range of 0.5 mm to 1.5 mm, in which case the vibration-absorbing element 13 has a good vibration-absorbing effect.

[0049] According to one embodiment of the utility model, the vibration damping member 13 includes a first section 131, a second section 132 and a third section 133, the first section 131 is constructed as a plurality and is arranged at intervals in the first direction; the second section 132 is constructed as a plurality and is arranged at intervals in the first direction, the plurality of second sections 132 are parallel to the plurality of first sections 131 and their projections in the second direction are arranged staggered; the third section 133 is constructed as a plurality extending in the second direction and arranged at intervals in the first direction, and one third section 133 is respectively connected to adjacent first sections 131 and second sections 132; wherein, at least one second section 132 is connected to the vibration damping housing 12, and at least one third section 133 is connected to the swing housing 141.

[0050] The vibration damper 13 can be bent in the vibration damping shell. Specifically, the vibration damper 13 includes a first section 131, a second section 132 and a third section 133 connected to each other, wherein the first section 131 is constructed as a plurality of sections and arranged at intervals in the first direction; the second section 132 is also constructed as a plurality of sections and arranged at intervals in the first direction, and the plurality of second sections 132 are parallel to the plurality of first sections 131 and their projections in the second direction are staggered; the third section 133 is also constructed as a plurality of sections arranged at intervals in the first direction, and at the same time, the third section 133 extends in the second direction and is located between two adjacent first sections 131 and second sections 132. It can be simply understood that the two ends of a third section 133 are respectively connected to a first section 131 and a second section 132 adjacent to each other. Therefore, the vibration damper 13 presents a bending structure similar to a "spring" through the connection relationship between the first section 131, the second section 132 and the third section 133, so that the vibration damper 13 can be deformed in the first direction and the second direction, thereby improving the vibration damping effect of the vibration damper 13.

[0051] In addition, the free end of one of the third connecting sections can also be connected to the swing housing 141. When the vibration damping member 13 is deformed, the vibration damping member 13 can drive the swing member 14 to move, thereby increasing the swing amplitude of the swing member 14 and further improving the vibration damping effect of the swing member 14.

[0052] According to one embodiment of the utility model, the front cover body 11 includes a frame 111 and a connecting arm 112. The frame 111 is covered on the outer periphery of the motor, and a avoidance hole suitable for the motor output shaft 101 to pass through is provided at the center of the frame 111; the connecting arm 112 is connected to the frame 111, and the front cover output shaft 102 is provided on the connecting arm 112. The vibration damping housing 12 is provided on the connecting arm 112 and is located between the motor output shaft 101 and the front cover output shaft 102.

[0053] Specifically, a frame 111 and a connecting arm 112 are provided on the front cover body 11, wherein the frame 111 is covered on the outer periphery of the motor, and the connecting arm 112 extends radially along the frame 111. A avoidance hole is provided at the center of the frame 111, and the motor output shaft 101 can pass through the avoidance hole. The front cover output shaft 102 is provided at one end of the connecting arm 112 away from the frame 111. Torque and rotation can be transmitted between the motor output shaft 101 and the front cover output shaft 102 through structures such as belts, so that the torque of the motor can be transmitted to other devices or structures for the normal operation of the overall device. The vibration-damping housing can be provided on the connecting arm 112 and located between the motor output shaft 101 and the front cover output shaft 102. A plane that fits at least part of the outer surface of the vibration-damping housing can be machined on the connecting arm 112 to improve the stability of the vibration-damping housing assembly. The vibration-damping housing is located between the motor output shaft 101 and the front cover output shaft 102, and can reduce vibration on the vibration transmission path, effectively reducing the vibration and noise of the overall structure.

[0054] In some embodiments, the vibration-damping shell, the vibration-damping member 13 , and the swinging member 14 may be integrally formed with the front cover body 11 .

[0055] In some embodiments, the material of the vibration-damping shell, the vibration-damping member 13 and the swinging member 14 can be a cast aluminum alloy or the like which is the same as the material of the front cover body 11 , wherein the counterweight block 142 in the swinging member 14 can be a steel structure.

[0056] The motor according to the utility model is briefly described below.

[0057] The motor according to the utility model includes the motor front cover assembly 1 in the above embodiment. Since the motor according to the utility model is provided with the motor front cover assembly 1 in the above embodiment, the motor front cover assembly 1 can reduce the vibration generated by the operation of the motor through the deformation of the vibration-damping member 13 and the swinging of the swinging member 14, thereby effectively reducing the vibration and noise of the overall structure of the motor.

[0058] The following is a brief description of the clothes processing device according to the present utility model.

[0059] According to the utility model, the clothing processing device includes the motor in the above embodiment. Since the clothing processing device according to the utility model is provided with the motor in the above embodiment, after the clothing processing device is equipped with the motor in the above embodiment, the noise and vibration generated by the motor will be buffered and weakened by the motor front cover assembly 1, thereby reducing the vibration and noise transmitted to the clothing processing device, and improving the user experience of the clothing processing device.

[0060] In summary, the motor front cover assembly 1 is provided with a frame 111 which is covered on the outer periphery of the motor, and a connecting arm 112 extending in the radial direction is formed on the frame 111, and a front cover output shaft 102 is provided on the connecting arm 112. The motor output shaft 101 passes through the center of the frame 111 and can transmit torque to the front cover output shaft 102 so as to be transmitted to other structures to be driven.

When the motor generates vibration during operation, the vibration is transmitted to the frame 111 and the connecting arm 112. At this time, the vibration damping member 13 can be deformed to absorb part of the vibration energy, and the swinging member 14 can also absorb part of the vibration energy by swinging. The front cover assembly is acted upon simultaneously by the swinging member 14 and the vibration damping member 13, thereby achieving double energy absorption, reducing the vibration and noise of the motor and improving the user experience.
