Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a clothes treatment device. BACKGROUND

[0002] The technical field of household appliances involves a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, vacuum cleaners, etc. The main trends in the development of these products are intelligentization, energy saving and environmental protection, user experience optimization, and the application of new materials. The optimization of user experience is achieved through design innovation and functional enhancement to meet the needs of consumers for health, convenience, and personalization.

[0003] As an important branch of household appliances, clothes treatment devices include clothes dryers and washer-dryers. Clothes dryers heat and dry clothes by recycling heat energy. The drum containing clothes rotates during the drying process to increase the contact area between the clothes and the hot air, making the drying more uniform and improving the drying efficiency. When the motor controls the rotation of the drum in the clothes treatment device, due to manufacturing tolerances, the geometric center of the drum may deviate from its original rotation center, causing the drum to have a circular runout. As a result, the drum will have periodic fluctuations, which will generate exciting forces on the output shaft of the motor, causing the output shaft to vibrate and produce noise. CONTENT OF THE INVENTION

[0004] The present application discloses a clothes treatment device that can reduce the vibration of the motor output shaft.

[0005] To achieve the above-mentioned purpose, the present application discloses a clothes treatment device, comprising:

[0006] A housing comprising a base, the housing comprising:

[0007] A drum rotatably connected to the housing, the drum forming a drying cavity inside, the drying cavity being used to accommodate clothes;

[0008] An air duct assembly in communication with the drying cavity, used to guide the drying gas into the drying cavity;

[0009] A heat supply system for providing a heat source to exchange heat between air and the heat source to form the drying gas;

[0010] A fan corresponding to the air duct assembly, the fan being used to send the drying gas into the air duct assembly and make the drying gas pass through the air duct assembly into the drying cavity;

[0011] a driving assembly disposed on the base, the driving assembly being in driving connection with the drum and the fan respectively, the driving assembly being configured to drive the drum and the fan to rotate, the driving assembly comprising:

[0012] an output shaft in driving connection with the drum to drive the drum to rotate;

[0013] a balancing assembly disposed on the output shaft, the balancing assembly being configured to compensate for the vibration generated by the output shaft when the output shaft rotates, the balancing assembly comprising:

[0014] a second balancing member disposed on the output shaft, the second balancing member being provided with a containing space, the containing space being filled with a plurality of solid particles, the plurality of solid particles being capable of colliding with each other when the output shaft rotates.

[0015] The balancing assembly is additionally provided on the output shaft of the second motor, and the collision between the solid particles can convert the vibration energy generated by the output shaft into heat energy generated by the collision to compensate for the vibration generated by the output shaft. By reducing the vibration of the output shaft, the noise caused by the vibration can be effectively reduced. Further, the stability of the clothes treatment device is ensured, the overall service life of the clothes treatment device is prolonged, the maintenance cost and the frequency of replacing the device of the user are reduced, and the cost performance of the device is improved.

[0016] As an optional implementation, the solid particles include at least one of iron sand, lead particles or steel balls.

[0017] In this way, the iron sand, the lead particles and the steel balls have relatively regular shapes (approximately spherical shapes), and such regular shapes make them have good fluidity in the containing space. When the output shaft rotates, the solid particles can move smoothly in the containing space, and the three kinds of solid particles can all generate heat energy through collision to effectively compensate for the vibration.

[0018] As an optional implementation, the total volume of the solid particles accounts for 10% to 90% of the volume of the containing space.

[0019] In this way, the volume ratio of the solid particles can make the distribution and flow state of the solid particles in the containing space optimal, so that the solid particles can generate heat energy through sufficient friction and collision to compensate for the vibration generated by the output shaft when the output shaft rotates.

[0020] As an optional implementation, the second balancing member has a ring structure, the containing space is an annular space, and the center of the second balancing member is located on the axis of the output shaft.

[0021] Thus, the annular structure can be evenly distributed in the circumference direction of the output shaft, and the solid particles in the annular space can move uniformly when the output shaft rotates, so that the vibration generated by the output shaft can be more stably and uniformly compensated.

[0022] As an optional implementation, the second balancing member further comprises:

[0023] A pushing member is arranged in the accommodation space, and when the second balancing member rotates, the pushing member can apply a pushing force in the rotation direction to the solid particles.

[0024] Thus, the pushing member can push the solid particles to move in the accommodation space, effectively enhancing the vibration reduction effect of the balancing assembly.

[0025] As an optional implementation, the pushing member is a plurality of pushing members, and the plurality of pushing members are distributed in the circumference direction of the second balancing member.

[0026] Thus, this makes each part of the second balancing member inside the second balancing member during rotation. The pushing member can apply a pushing force to the solid particles.

[0027] As an optional implementation, the pushing member is a plate-shaped structure, and the pushing member extends in the radial direction of the second balancing member.

[0028] Thus, the plate-shaped pushing member can more effectively apply a pushing force to the solid particles, which can cover a larger area in the radial direction, increase the contact area with the solid particles, and enable the pushing member to more fully push the solid particles to move during rotation of the output shaft. The balancing assembly can improve the compensation effect of the vibration of the output shaft, especially when the rotation speed of the output shaft changes, the distribution of the solid particles can be adjusted more quickly to adapt to the vibration caused by the new eccentric state.

[0029] As an optional implementation, the second balancing member comprises:

[0030] An inner ring wall is arranged around the output shaft;

[0031] An outer ring wall is arranged around the inner ring wall, and the accommodation space is formed between the outer ring wall and the inner ring wall;

[0032] The pushing member is connected to the outer ring wall, and the pushing member is arranged in a spaced manner with the inner ring wall.

[0033] Thus, when the balancing medium is solid particles, a plurality of solid particles can flow between a plurality of subspaces through the spacing between the pushing member and the inner ring wall, so that the solid particles in each subspace can also collide with each other to generate heat energy, and the vibration generated by the output shaft can be more fully compensated.

[0034] As an optional implementation, the second balancing member is a plurality of second balancing members, each of the plurality of second balancing members is a ring structure, and the plurality of second balancing members are sequentially sleeved along a radial direction of the output shaft.

[0035] In this way, when only the second balancing member is arranged on the output shaft, the limited space in the housing is effectively utilized under the premise of ensuring the ring structure of the second balancing member, so that the outermost second balancing ring can be fixed on the output shaft, and each second balancing member can realize the effect of compensating vibration. When the output shaft rotates at high speed, the plurality of second balancing members work cooperatively to better suppress the relatively large vibration generated during high-speed rotation, thereby improving the stability of the entire clothes processing device.

[0036] As an optional implementation, the second balancing member further comprises:

[0037] A plurality of separation rings are arranged in the accommodation space, centers of the plurality of separation rings are located on the axis of the output shaft, the plurality of separation rings are sequentially arranged along the radial direction of the output shaft, and adjacent two separation rings are arranged at intervals to separate the accommodation space into a plurality of annular spaces, and the plurality of annular spaces are respectively filled with the solid particles.

[0038] In this way, the second balancing member is of an integrated structure, which is designed more simply and compactly, reduces the cumbersome steps in the installation process, reduces the probability of error, significantly improves the construction efficiency, and reduces the number of parts. This not only simplifies the installation process, but also reduces the connection points between parts, thereby reducing the risk of failure caused by loose or damaged connection points. The flow range of the solid particles in each annular space is limited, so that the solid particles move orderly in the respective annular spaces to compensate for vibration, thereby enhancing the stability of the entire balancing assembly.

[0039] As an optional implementation, the balancing assembly further comprises:

[0040] A connecting bracket is connected to the output shaft.

[0041] The second balancing member is connected to the connecting bracket.

[0042] In this way, this connection mode enables the second balancing member to maintain a stable positional relationship when the output shaft rotates. The connecting bracket provides a reliable connection basis for the second balancing member, prevents displacement of the second balancing member during operation, and ensures the stability of the structure of the entire balancing assembly.

[0043] As an optional implementation, the connecting bracket is a ring-shaped bracket, the ring-shaped bracket is sleeved on the output shaft, the second balancing member is a ring structure, and the second balancing member is sleeved on an outer periphery of the ring-shaped bracket.

[0044] Thus, the annular support provides a stable support structure for the second balance member, and this design ensures that the annular support and the annular structure of the second balance member can better match, so that the connection between the second balance member and the output shaft is more stable when the output shaft rotates, thereby ensuring the stability of the balance assembly.

[0045] As an optional implementation, the connecting support comprises:

[0046] a sleeve, which is sleeved on the output shaft and can transmit torque between the sleeve and the output shaft;

[0047] a support ring, which is arranged around the outer periphery of the sleeve and is coaxially arranged with the sleeve, and the second balance member is sleeved on the outer peripheral wall of the support ring;

[0048] a support rib, which is connected between the sleeve and the support ring.

[0049] Thus, the sleeve is sleeved on the output shaft and can transmit torque, which ensures reliable power transmission between the connecting support and the output shaft, enhances the stability of the connecting support on the output shaft, prevents the connecting support from sliding or deviating relative to the output shaft, and thereby improves the structural stability of the entire balance assembly. The support ring is arranged around the outer periphery of the sleeve and is coaxially arranged with the sleeve, which further enhances the integrity of the connecting support, and the coaxial arrangement makes the force transmission more uniform, reducing the additional stress caused by eccentricity. When the output shaft rotates at high speed, the design of the support rib can effectively prevent the connecting support from deforming or being damaged. The support ring provides a matching outer peripheral wall for the sleeve of the second balance member, so that the second balance member can be stably installed on the connecting support, which helps to improve the compensation effect of the balance assembly on the vibration of the output shaft.

[0050] As an optional implementation, the support rib is a plurality of support ribs, each of which extends in the radial direction of the output shaft, and the plurality of support ribs are distributed in the circumferential direction of the output shaft.

[0051] Thus, the circumferentially distributed support ribs ensure that no local area bears excessive force, thereby avoiding the risk of damage to the connecting support due to local stress concentration, which helps to improve the overall structural strength and stability of the connecting support and prolong its service life.

[0052] As an optional implementation, the connecting support is made of a hard material.

[0053] Therefore, the connecting bracket made of hard material can provide better structural stability, so as to ensure that the connecting bracket can withstand corresponding force and vibration during rotation of the output shaft, reduce the possibility of deformation of the connecting bracket during long-term use, and maintain the stability of the overall structure of the balancing assembly.

[0054] As an optional implementation, the connecting bracket is made of plastic.

[0055] Therefore, the plastic material generally has a lighter mass, which helps to reduce the overall weight of the clothes processing device. The plastic material also has good corrosion resistance and can resist the corrosion of chemicals and moisture that may be encountered in daily use, thereby prolonging the service life of the connecting bracket. The plastic material can be formed into various complex shapes through molding processes such as injection molding, which provides greater flexibility for the design of the connecting bracket. In addition, the plastic material generally has a lower cost, and the use of a plastic connecting bracket can reduce production costs, thereby reducing product prices and improving market competitiveness.

[0056] As an optional implementation, the second balancing member made of rubber material has good elasticity and damping characteristics, which can absorb and dissipate vibration energy, further enhancing the balancing effect.

[0057] As an optional implementation, the driving assembly comprises:

[0058] The first motor is connected to the fan and is used to drive the fan to rotate.

[0059] The second motor is drivingly connected to the drum through a transmission belt and is used to drive the drum to rotate. The second motor comprises the output shaft.

[0060] Therefore, the rotational speeds of the drum and the fan can be controlled separately. The fan is controlled by the first motor, and the second motor only controls the rotation of the drum.

[0061] As an optional implementation, the second motor is a fixed-frequency AC motor.

[0062] Since the fixed-frequency AC motor has a lower cost, the overall cost of the machine can be reduced. Moreover, the fixed-frequency AC motor has a relatively simple structure and high-efficiency operating characteristics, and has a high energy conversion efficiency, which can save energy costs for the clothes processing device that operates for a long time. The maintenance and repair costs are relatively low, and the service life is long, which can reduce maintenance costs and downtime.

[0063] As an optional implementation, the second motor further comprises:

[0064] The motor housing;

[0065] The output shaft is arranged in the motor shell, and the output shaft comprises a first end and a second end, and the first end and the second end respectively extend out of two opposite side walls of the motor shell.

[0066] The first end is in transmission connection with the roller, and the balance assembly is arranged at the second end.

[0067] In this way, the two ends of the output shaft extend out of the motor shell, and the balance assembly is additionally arranged at the second end, so that the forces on the two ends of the output shaft during rotation are more balanced, the center of gravity of the output shaft can be balanced, the vibration of the output shaft is further reduced, and the stability of the driving assembly is improved.

[0068] As an optional implementation, the second motor further comprises:

[0069] An axial positioning structure is arranged between the balance assembly and the output shaft to prevent the balance assembly from moving axially relative to the output shaft.

[0070] In this way, the axial positioning structure can ensure that the position of the balance assembly on the output shaft is fixed, and displacement of the balance assembly in the axial direction is prevented, especially when the output shaft rotates at a high speed, the unstable compensation vibration effect caused by movement of the balance assembly can be reduced, thereby improving the stability and reliability of the entire driving assembly.

[0071] Compared with the prior art, the application has the following beneficial effects:

[0072] The laundry treatment device provided by the embodiments of the application additionally arranges a balance assembly on the output shaft of the second motor, and when the output shaft rotates, the collision between solid particles can convert the vibration energy generated by the output shaft into heat energy generated by collision, so as to compensate for the vibration generated by the output shaft. By reducing the vibration of the output shaft, the noise caused by the vibration can be effectively reduced. Further, the stability of the operation of the laundry treatment device is ensured, the overall service life of the laundry treatment device is prolonged, the maintenance cost of the user and the frequency of replacement of the equipment are reduced, and the cost performance of the device is improved.

[0101] The laundry treatment device is an important branch of household appliances, and the laundry treatment device includes a clothes dryer and a washer-dryer. The clothes dryer uses heat energy to heat and dry clothes by recycling, and a drum containing clothes rotates during the drying process to increase the contact area of the clothes with hot air, making the drying more uniform and improving the drying efficiency. When the motor controls the rotation of the drum in the laundry treatment device, due to the manufacturing tolerance of the drum, the geometric center of the drum deviates from its original rotation center, so that the drum produces circular runout, so the drum has periodic fluctuations, which generates exciting force to the motor, causing the motor to vibrate and produce noise, which brings a bad user experience.

[0102] Based on this, the embodiment of the present application discloses a laundry treatment device, a balancing assembly is arranged at the shaft end of the motor for controlling the rotation of the drum, which is used to compensate for the vibration generated by the output shaft of the motor during rotation, thereby reducing noise.

[0103] The technical solutions of the present application will be further described below in conjunction with the embodiments and the drawings.

[0104] Please refer to Figure 1 , Figure 1 The structure schematic diagram of the laundry treatment device 100 disclosed by the embodiment of the present application. The embodiment of the present application discloses a laundry treatment device 100, which can be a clothes dryer or a washer-dryer.

[0105] The laundry treatment device 100 includes a housing 1, which serves as the external structure of the device, typically made of metal or plastic, for protecting the internal components of the laundry treatment device 100 and providing a stable support. The housing 1 is designed with durability, heat dissipation performance, noise control, safety, and maintainability in mind. The housing 1 is designed to surround the drum 2 inside to accommodate and protect the drum 2 and other internal structures. The housing 1 includes a base for locating part of the internal structures.

[0106] In some embodiments, referring to Figure 2 , Figure 2 The laundry treatment device 100 disclosed in the embodiments of the present application is shown in the internal structure diagram. The housing 1 is provided with a drum 2, and the drum 2 forms a drying cavity for accommodating laundry. The drum 2 accommodating laundry rotates during the drying process to increase the contact area of the laundry with hot air, making the drying more uniform and improving the drying efficiency. The drum 2 is usually made of stainless steel to ensure strength and corrosion resistance. The drum 2 can be provided with protrusions inside, which can increase the contact area with wet laundry and promote the conduction of hot air to the laundry, thereby improving the drying efficiency.

[0107] In some embodiments, in combination with Figure 2 The housing 1 is provided with a feeding port 1a, which is arranged in the axial direction of the drum 2 and corresponds to the drum 2, for feeding laundry into the drum 2.

[0108] In some embodiments, in combination with Figure 3 , Figure 3 The laundry treatment device 100 disclosed in the embodiments of the present application is shown in the internal structure diagram (omitting the drum 2), and the housing 1 is provided with an air duct assembly 3, which is in communication with the drying cavity and is used to guide the drying gas into the drying cavity. The air duct is designed with aerodynamics in mind to optimize the airflow path, reduce air resistance, and improve the transmission efficiency of the drying gas. The air duct can be provided with a fan inside, and the fan can be provided with a wind guide inside, which is used to guide the airflow to the drum of the laundry treatment device 100, so that the laundry can be fully contacted with the drying gas.

[0109] In some embodiments, in combination with Figure 3 The housing 1 is provided with a heating system 4, which is used to provide a heat source, which can adopt electric heating or heat pump system, etc., so that the air exchanges heat with the heat source to form drying gas. The efficient heating system 4 can quickly transfer heat to the air duct, reduce energy consumption, and at the same time provide enough heat to ensure that the laundry can be dried in a short time.

[0110] In some embodiments, in combination with Figure 3The shell 1 is provided with a fan (not shown in the figure), which is correspondingly arranged with the air duct assembly 3. The fan is used to send drying gas into the air duct assembly 3, and make the drying gas enter the drying cavity through the air duct assembly 3.

[0111] Among them, the main dryer includes heat pump type dryer, condensing type dryer and exhaust type dryer, different types of dryers have the above structure, but the drying principle is different.

[0112] The working principle of heat pump type dryer is usually based on heat pump technology, which uses recycled heat to heat and dry clothes. The working principle of heat pump type dryer is to realize low temperature drying through heat pump circulation system (heating system 4). The heat pump circulation system is usually composed of compressor 6, condenser, throttle valve and evaporator, and is filled with appropriate circulating working medium. In the working process, the low-temperature and low-pressure working medium absorbs the heat of the surrounding environment (such as the inside of the dryer) in the evaporator and evaporates into gas. In this process, the working medium absorbs the moisture in the clothes, and its temperature rises. Then, the high-temperature working gas is sucked into the compressor 6 and compressed, and the temperature and pressure increase, and it is transformed into high-temperature and high-pressure gas. This high-temperature working gas (drying gas) then flows into the condenser, where it releases heat and transfers heat to the air inside the dryer through the air duct assembly 3 (the air duct assembly 3 is in communication with the drying cavity, used to guide the drying gas into the drying cavity). At the same time, the working medium itself condenses into liquid. The condensed liquid working medium is depressurized by the throttle valve and enters the evaporator, where it absorbs more heat and evaporates into gas again, completing the cycle. The fan drives the gas flow in the air duct assembly 3 to achieve circulation. This cycle repeats until the moisture in the clothes is completely evaporated, achieving the drying effect. The advantage of heat pump type dryer is that it has higher energy efficiency, because it can recover heat from the environment for drying, instead of directly consuming electricity to generate heat like traditional resistance heating dryers. In addition, the temperature produced by the heat pump type dryer during operation is relatively low, which is more gentle to clothes, helping to protect the fibers of clothes and reduce the risk of shrinkage and damage.

[0113] The working principle of condensing type dryer is based on condensation technology, which is used to remove water from wet clothes. The heater (heating system 4) inside the dryer is powered to heat, producing dry hot air, which is blown into the drum 2 of the dryer by the fan, passing through the wet clothes and absorbing the moisture in the clothes. The humid hot air then flows through the condenser, where the cooling surface of the condenser causes the water vapor in the air to condense into water droplets, which are collected in the container inside the condenser or discharged through the connected hose. The dry hot air loses moisture after passing through the condenser and becomes dry and is heated again, circulating in the air duct assembly 3 into the drum 2 again to continue drying the clothes. The condensed water is discharged outside the dryer through a pre-set way (water tank or drain pipe).

[0114] The exhaust type clothes dryer is a device that removes moisture from clothes by heating air and blowing it into the inside of the drum 2. The clothes dryer is equipped with heating elements (heating system 4), usually electric heating wires, which heat the air drawn in, and the heated air is delivered to the inside of the drum 2 of the clothes dryer through the fan in the air duct assembly 3, the hot air passes through the clothes, absorbs the moisture in the clothes, and flows to the other end of the clothes dryer with the hot air, and the hot air containing moisture is discharged to the indoor or outdoor environment through the exhaust pipe.

[0115] The washer-dryer usually integrates the washing and drying functions, and they can use different drying technologies to dry the clothes. The heat pump type is suitable for families pursuing drying quality due to its low-temperature drying, energy saving, environmental protection, and gentle to clothes. The condensing type and the exhaust type have relatively simple structure and low cost, which are suitable for users with limited budget.

[0116] In some embodiments, in combination Figure 2 The housing 1 is also provided with a drive assembly 5, which is arranged on the base. The drive assembly 5 is in driving connection with the drum 2 and the fan respectively. The drive assembly 5 can drive the drum 2 and the fan to rotate synchronously or separately. When the drum 2 and the fan are arranged on the same motor, they rotate synchronously. When the drum 2 and the fan are controlled by two motors respectively, they rotate separately. This embodiment does not limit this.

[0117] In some embodiments, the drive assembly 5 includes a first motor (not shown in the figure), which is connected to the fan for driving the fan to rotate.

[0118] In some embodiments, the drive assembly 5 further includes a second motor 51 in driving connection with the drum 2 for driving the drum 2 to rotate.

[0119] In some embodiments, in combination Figure 2 and Figure 4 , Figure 4 The structure diagram of the second motor 51 (including the belt pulley 22) disclosed in the embodiments of the present application. The second motor 51 includes an output shaft 511, which is in driving connection with the drum 2 through a transmission belt 21 to drive the drum 2 to rotate. Since the diameter of the drum 2 is much larger than that of the output shaft 511, when the output shaft 511 rotates at high speed, the transmission belt reduces the rotating speed of the drum 2, so that the clothes in the drum 2 rotate at a slower speed, increasing the contact area between the clothes and the hot air, and making the drying more uniform.

[0120] It should be noted that the output shaft 511 usually has two states, namely low-speed rotation state and high-speed rotation state, and the low speed usually refers to the rotating speed of the motor in the starting stage, and the high speed usually refers to the rotating speed of the output shaft 511 exceeding the rotating speed of the output shaft 511 when the suspension system resonates at a low frequency, and the high and low of the two rotating speeds are only relative concepts, and are not a certain speed range. The low frequency resonance refers to a phenomenon that the vibration frequency of the washing machine matches the natural frequency of the washing machine during the operation of the washing machine, so that the vibration amplitude is significantly increased.

[0121] In some embodiments, in combination Figure 2 and Figure 4 The second motor 51 further comprises a belt pulley 22 arranged on the output shaft 511, and the belt pulley 22 is in transmission connection with the drum 2 through the transmission belt 21.

[0122] Since one end of the driving assembly 5 is connected with the drum through the transmission belt 21, and the other end is connected with the fan, when the rotating speeds of the drum 2 and the fan are adjusted, they can only be adjusted synchronously, and when it is desired to control the drum 2 to rotate rapidly, the rotating speed of the output shaft 511 is increased, but the rotating speed of the fan cannot be reduced at the same time, and the fan can only increase the rotating speed synchronously with the output shaft 511 and the drum 2. In order to control the rotating speeds of the drum 2 and the fan respectively, the fan is controlled by the first motor, and the second motor 51 only controls the rotation of the drum 2. In addition, since there are manufacturing and installation tolerances of the drum 2, the geometric center of the drum 2 deviates from the original rotating center, so that the drum 2 generates circular runout, and then generates exciting force to the second motor 51, so that the motor vibrates and generates noise.

[0123] Therefore, the balancing assembly 513 is additionally arranged on the output shaft 511 of the second motor 51, and the vibration generated by the output shaft 511 is compensated when the output shaft 511 rotates. By reducing the vibration of the output shaft 511, the noise caused by the vibration can be effectively reduced, and the use experience of the clothes treatment device 100 is improved. In addition, since the output shaft 511 is connected with the drum 2 through the transmission belt 21, the transmission belt 21 is connected with the output shaft 511 through the belt pulley 22 arranged on the output shaft 511, the vibration is compensated by arranging the balancing assembly 513, the vibration of the belt pulley 22 is reduced, the relative displacement of the transmission belt 21 on the belt pulley 22 due to the vibration is further reduced, and even the possibility of falling off is reduced. The wear of the transmission belt 21 and the belt pulley 22 caused by the vibration is also reduced, the stability of the operation of the clothes treatment device 100 is further ensured, the overall service life of the clothes treatment device 100 is prolonged, the maintenance cost and the replacement frequency of the user are reduced, and the cost performance of the device is improved.

[0124] The balancing assembly 513 is arranged on the output shaft 511 and can rotate with the output shaft 511, and the balancing assembly 513 can increase the moment of inertia of the output shaft 511 when the output shaft 511 rotates. In this way, the increase of the moment of inertia can help to improve the stability of the rotation of the output shaft 511, and further reduce the vibration of the output shaft 511 during rotation, reduce the noise generated by the clothes treatment device 100 during operation, and prevent the transmission belt 21 from slipping or even falling off the belt pulley 22 due to vibration.

[0125] In some embodiments, in combination Figure 4 The balancing assembly 513 includes a first balancing member 5131 arranged on the output shaft 511. Since the center of mass of the first balancing member 5131 is located on the axis of the output shaft 511, the rotation stability of the output shaft 511 is effectively improved when the output shaft 511 rotates, and further the vibration of the output shaft 511 is reduced.

[0126] In some embodiments, in combination Figure 4 The first balancing member 5131 can have a uniform mass distribution and a ring structure, and the first balancing member 5131 is sleeved on the output shaft 511, and the center of the first balancing member 5131 is located on the axis of the output shaft 511.

[0127] The ring structure makes the mass distribution of the first balancing member 5131 more uniform in the circumferential direction, and can ensure that the force in the circumferential direction of the first balancing member 5131 is more uniform when the output shaft 511 rotates, and each part on the circumference can generate a more uniform centrifugal force. Compared with irregular shapes, it is more conducive to maintaining the stability of rotation, can more accurately compensate for the vibration of the output shaft 511, reduce the vibration generated by the rotation of the output shaft 511, and further reduce the noise, and reduce the possibility of displacement of the transmission belt 21 relative to the belt pulley 22.

[0128] In some embodiments, the second motor 51 is a fixed-frequency AC motor. Since the fixed-frequency AC motor has a lower cost, the cost of the entire machine can be reduced. And the fixed-frequency AC motor has stable speed and reliable operation performance, can ensure the stability and efficiency of the work load, can provide stable power output, and ensure the normal operation of the device. The fixed-frequency AC motor has a relatively simple structure and high efficiency operation characteristics, and has a high energy conversion efficiency, which can save energy costs for the clothes treatment device 100 that runs for a long time. Its maintenance and repair cost is relatively low, and the service life is long, which can reduce the maintenance cost and downtime.

[0129] In some embodiments, when the garment handling device 100 is a 110L platform and the motor is a fixed-frequency AC motor, a first balancing component 5131 is added to simulate and test the maximum amplitude of vibration generated by the second motor 51 and the pulley 22. The base and inner cross-section of the second motor 51 are constrained to remain stationary, and a certain force of 100N is applied to the output shaft 511 to characterize the comprehensive eccentric force, including eccentricity factors. When the output shaft 511 is in a high-speed rotating state, the first balancer 5131 is 180 degrees out of phase with the output shaft 511 to balance the eccentric force. The balance distance between the center of mass of the first balancer 5131 and the axis of the output shaft 511 is set to 0.001mm, and the rotational speed of the output shaft 511 is 3000rpm. The mass of the first balancer 5131 is applied in sequence as follows: 100g, 200g, 300g, 400g, 500g, 600g, 700g, 800g, 900g, 1000g. The results are shown in Table 1 from the simulation test.

[0130]

[0131] Table 1

[0132] Table 1 can be used to draw the following diagram: Figure 17 The graph shows the trend of the maximum amplitude corresponding to the mass of the first balancing component 5131 (the maximum amplitude of the second motor 51 and the maximum amplitude of the pulley 22 are both rounded to two decimal places). Figure 17 This is a graph showing the trend of the maximum amplitude corresponding to the mass of the first balancing component 5131 disclosed in this application. As can be seen from the graph, as the mass of the first balancing component 5131 increases, the overall maximum amplitude of the second motor 51 and the maximum amplitude of the pulley 22 gradually decrease. Therefore, the greater the mass of the first balancing component 5131, the smaller the amplitude of the second motor 51 and the pulley 22, resulting in better vibration compensation. The possibility of the transmission belt 21 experiencing relative displacement or even detachment on the pulley 22 due to vibration is reduced. The wear of the transmission belt 21 and pulley 22 caused by vibration further ensures the operational stability of the clothing processing device 100, helps extend the overall service life of the clothing processing device 100, reduces user maintenance costs and the frequency of equipment replacement, and improves the cost-effectiveness of the equipment.

[0133] In some embodiments, the mass of the first balancing component 5131 can be determined to be 150g~400g based on the actual working conditions. And according to the following formula (1), it can be seen that the greater the load on the roller 2, the greater the mass of the first balancing component 5131 required.

[0134] (1)

[0135] Where m is the mass of the first balancing component 5131, and M is the mass of the roller 2 when fully loaded, M = 10 kg. is the outer diameter of the first counterbalance 5131, k is a correlation coefficient, is the radius of the drum 2, is the radius of the pulley 22, is the length of the drum, is the axial distance between the drum 2 and the pulley 22.

[0136] The main function of the first counterbalance 5131 is to compensate for the vibration generated when the output shaft 511 rotates. According to actual work tests, if the mass is less than 150g, the amount of vibration compensation for the output shaft 511 is small, and the vibration of the pulley 22 on the output shaft 511 is still relatively obvious. The transmission belt 21 will produce displacement on the pulley 22, which will affect the stability and service life of the entire device. If the mass of the first counterbalance 5131 exceeds 400g, the volume of the first counterbalance 5131 is large, which will interfere with the inner wall of the base of the clothes treatment device 100. Therefore, the first counterbalance 5131 with a mass of 150g to 400g can achieve better vibration compensation effect in a limited installation space, effectively improving the rotation stability of the output shaft 511.

[0137] In some embodiments, the first counterbalance 5131 is made of steel. Steel is a high-strength material that can withstand large stresses and deformations. Steel has a large density, so the same volume can be used to make a first counterbalance 5131 with a larger mass, which can better compensate for vibration. In the clothes treatment device 100, the first counterbalance 5131 needs to compensate for the vibration generated when the output shaft 511 rotates. The first counterbalance 5131 made of steel can provide sufficient strength and durability to ensure that it will not be easily damaged during long-term use. Steel generally has a certain corrosion resistance, which can prolong the service life of the first counterbalance 5131 and reduce the frequency of maintenance and replacement. In addition, choosing steel as the material of the first counterbalance 5131 can effectively control the production cost while ensuring product quality.

[0138] In some embodiments, the thickness of the first balancing piece 5131 is 3-7 mm. If the thickness of the first balancing piece 5131 is less than 3 mm, the first balancing piece 5131 cannot provide sufficient strength and stability, is prone to deformation, affects the service life of the device, and in order to ensure that the mass of the first balancing piece 5131 is large enough, the outer diameter of the corresponding first balancing piece 5131 needs to be set larger. Since the second motor 51 is usually arranged on the base, the base usually has components such as the fan assembly of the air duct assembly 3 and the heat supply system 4, so the space of the base is limited, and the outer diameter of the first balancing piece 5131 that is too large will interfere with the inner wall of the base. If the thickness of the first balancing piece 5131 is greater than 7 mm, it is also likely to interfere with the inner wall of the base of the clothes treatment device 100. Therefore, the thickness is set to 3-7 mm, so that the first balancing piece 5131 can achieve better vibration compensation effect under the premise that there is enough installation space for other components on the base, effectively improving the rotation stability of the output shaft 511.

[0139] In some embodiments, according to actual working conditions, the outer diameter of the first balancing piece 5131 is 60-100 mm.

[0140] According to the above formula (1) and the following rotational inertia formula (2), and combined with the actual working conditions, it can be concluded that when the outer diameter of the first balancing piece 5131 is less than 60 mm, the rotational inertia of the first balancing piece 5131 is too small to effectively compensate for the vibration of the output shaft 511, and the vibration of the belt pulley 22 on the output shaft 511 is still obvious. The transmission belt 21 will displace or even fall off the belt pulley 22, thereby affecting the stability and service life of the entire device. If the outer diameter of the first balancing piece 5131 exceeds 100 mm, the first balancing piece 5131 has a large volume, and since the second motor is usually arranged on the base, the base of the clothes treatment device 100 usually also has other components (such as the fan assembly of the air duct assembly 3 and the heat supply system 4), so the space of the base is limited, and the first balancing piece 5131 will interfere with the inner wall of the base. Therefore, the first balancing piece 5131 with an outer diameter of 60-100 mm can achieve better vibration compensation effect under the limited installation space, effectively improving the rotation stability of the output shaft 511.

[0141] (2)

[0142] wherein I is the rotational inertia of the first balancing piece 5131 rotating around the axis of the output shaft 511, m is the mass of the first balancing piece 5131, is the outer diameter of the first balancing piece 5131.

[0143] In some embodiments, combined with Figure 4 and Figure 8 ,Figure 8 This is a cross-sectional view of the second balancing member 5132 when the balancing medium is a liquid. The balancing assembly 513 includes the second balancing member 5132, which is fixed relative to the output shaft 511. The second balancing member 5132 has a receiving space 5132a inside, which contains the balancing medium. When the output shaft 511 rotates, the balancing medium can move within the receiving space 5132a to compensate for the vibration generated by the output shaft 511.

[0144] In some embodiments, the balancing medium includes a liquid medium. The liquid medium has good fluidity and can rapidly adjust its distribution according to centrifugal force and vibration. Due to the excitation force, the second balancing member 5132 has an initial eccentricity e relative to the output shaft 511. Under the action of centrifugal force, the liquid gradually deviates to one side. After the rotational speed stabilizes, the center of gravity of the liquid shifts by an offset y relative to the center of the second balancing member 5132. The excitation force F of the second balancing member is proportional to the rotational speed. The mass M of the second balancing component containing liquid and the excitation force cause the eccentricity e of the second balancing component 5132, i.e. When the output shaft 511 rotates at low speed, the centrifugal force on the liquid is small, and the eccentric position of the output shaft 511 and the liquid distribution position are roughly in the same direction. When the rotational speed of the output shaft 511 exceeds the rotational speed of the output shaft 511 at the low-frequency resonance of the suspension system (critical speed), the centrifugal force on the liquid becomes larger. As the pressure increases, F increases, causing the offset y of the liquid response to also increase and exceed the eccentricity e generated by the second balancing element 5132. The centrifugal force generated by y This is greater than the excitation force F. Centrifugal force is an inertial force; the greater the centrifugal force, the greater the inertia. Due to its greater inertia, the liquid cannot keep up with the changes in the excitation force F and thus lags behind. Therefore, there is a phase difference between the excitation force F and the offset y of the liquid's center of gravity, and this phase difference increases with increasing rotational speed. When passing the critical speed, the phase difference between the two vectors reaches 90°, and their directions reverse, at which point the amplitude y reaches its maximum. Beyond the critical speed, as the rotational speed increases, the phase difference between the excitation force F and the offset y of the liquid's center of gravity becomes increasingly larger. Far from the critical speed, the phase difference between the two vectors is 180°, and the excitation force and response directions are completely opposite. This reduces the centrifugal force generated by the eccentricity of the output shaft 511, thereby reducing the vibration of the output shaft 511.

[0145] Low-frequency resonance refers to a low-frequency, oscillating resonance that drum 2 inevitably experiences during rotation. At this speed, drum 2 is prone to oscillation, causing the machine body to shift. Because it is difficult to control the speed at low frequencies, and because the resonant speed is affected by the load inside drum 2, it changes with the load, especially under heavy loads, the low-frequency resonant speed of the washing machine will become smaller.

[0146] In some embodiments, the liquid medium can be saline and / or silicone oil, i.e. saline or silicone oil or a mixture of saline and silicone oil.

[0147] In a first possible implementation, the saline is a solution formed by dissolving salt in water, and the density thereof can be adjusted by changing the concentration of the salt. In the balancing assembly 513, a suitable density (e.g. 1.0 g / cm3-1.5 g / cm3) helps to better achieve vibration compensation, and a higher density can provide a greater inertial force to compensate for vibration when the output shaft 511 rotates, especially when dealing with vibrations of a larger amplitude or generated at a higher speed. By adjusting the concentration of the saline to change the density, the balancing assembly 513 can more accurately adapt to the operating state of the device. Moreover, the saline is low in preparation cost, and the raw materials (salt and water) are easy to obtain, thereby reducing the production cost. In a second possible implementation, the silicone oil has high chemical stability and is not prone to chemical reactions with other substances. The silicone oil will not deteriorate or lose its balancing effect due to a reaction with the materials of the balancing assembly 513 (e.g. the container wall, etc.), which helps to maintain the long-term stable operation of the clothes treatment device 100 and reduces the decline in vibration compensation ability due to changes in the balancing medium. The silicone oil also has certain lubricity, which can reduce the friction between internal components. When the output shaft 511 rotates, the distribution of the silicone oil in the second balancing member 5132 can not only compensate for vibration but also reduce energy loss and noise due to component friction, which helps to improve the overall efficiency and service life of the device. In addition, the silicone oil is a colorless, odorless, non-toxic and non-volatile liquid. It can be used for a long time and will not cause harm to the human body. In a third possible implementation, the saline and the silicone oil are used in combination. Not only can the two liquids of different densities be used to appropriately adjust the overall density of the balancing medium and improve the flowability of the balancing medium, but also the balancing medium has high chemical stability, which makes the movement of the balancing medium in the balancing assembly 513 smoother, further improves the ability of the balancing medium to compensate for vibration, and relatively reduces the production cost of the balancing medium when the balancing medium is silicone oil by mixing the saline.

[0148] In some embodiments, the volume of the liquid medium accounts for 30%-50% of the volume of the accommodation space 5132a. Such a liquid volume ratio can make the distribution and flow state of the liquid medium in the accommodation space 5132a optimal, so that the liquid can timely adjust the position to compensate for the vibration when the output shaft 511 rotates.

[0149] When the volume of the liquid is too small, the balancing medium distributed in the accommodation space 5132a is too little to effectively compensate for the vibration, and the effect of reducing the vibration is not obvious. That is, when the volume of the liquid is less than 30%, the mass of the liquid is not enough, and the balancing medium cannot balance the vibration of the output shaft 511 of the motor in the clothes treatment apparatus 100. If the volume of the liquid is too large, the movable range of the liquid medium inside is too small, and the effect of automatically adjusting the center of mass position according to the eccentric position of the output shaft 511 is not good, which results in the inability to effectively compensate for the vibration. That is, when the volume of the liquid is greater than 50%, the movement space of the liquid is not enough, and the vibration of the output shaft 511 of the motor in the clothes treatment apparatus 100 cannot be effectively compensated.

[0150] Preferably, the volume of the liquid medium accounts for 40% of the volume of the accommodation space 5132a. While ensuring the cost, the liquid medium with a volume of 40% can better distribute and flow in the accommodation space 5132a, and the liquid can timely adjust the position to compensate for the vibration generated when the output shaft 511 rotates.

[0151] In some embodiments, in combination Figure 10 The balancing medium includes a plurality of solid particles, Figure 10 When the balancing medium is solid particles, the plurality of solid particles can collide with each other, and the solid particles can also collide with the side wall of the second balancing member 5132, so that the vibration energy generated by the output shaft 511 is converted into heat energy generated by the collision to compensate for the vibration generated by the output shaft 511.

[0152] In some embodiments, the solid particles include at least one of iron sand, lead particles, or steel balls. The iron sand, lead particles, and steel balls have relatively regular shapes (approximately spherical shape). The regular shape makes them have good fluidity in the accommodation space 5132a, and when the output shaft 511 rotates, the solid particles can move smoothly in the accommodation space 5132a. Moreover, the three kinds of solid particles can all generate heat energy by collision to effectively compensate for the vibration.

[0153] In a first possible implementation, the solid particles are iron sand. The iron sand has a relatively large density, and when colliding with other particles or the side wall of the second balancing member 5132, it can more effectively convert the vibration energy of the output shaft 511 into heat energy due to its relatively large mass under the same change in speed according to the law of conservation of energy. When the output shaft 511 generates a certain vibration speed, the momentum change of the iron sand particles when colliding is large, so that the vibration energy can be more fully absorbed and converted, and the vibration of the output shaft 511 is better compensated. Moreover, the iron sand particles are relatively irregular in shape but hard in texture, and are not easily worn or deformed during long-term use, so that the distribution state of the iron sand in the accommodation space 5132a can be maintained, and the vibration energy can be continuously and stably converted. As a relatively common and low-cost material, the use of iron sand as solid particles can effectively control the production cost while meeting the functional requirements for compensating the vibration of the output shaft 511.

[0154] In a second possible implementation, the solid particles are lead particles. The lead particles also have a relatively high density, and when colliding with other particles or the side wall of the second balancing member 5132, they can effectively absorb the vibration energy of the output shaft 511 and convert it into heat energy. The lead has a relatively soft texture, which makes it have a certain damping effect when colliding. It can slow down the collision speed between particles and between particles and the side wall, so that the energy conversion process is more gentle, reducing the impact on the structure of the balancing assembly 513 caused by violent collisions, thereby prolonging the service life of the balancing assembly 513, and also stably compensating for the vibration of the output shaft 511.

[0155] In a third possible implementation, the steel balls have a relatively high hardness and are not easily worn during long-term mutual collisions and collisions with the side wall. This enables the steel balls to maintain their shape and mass characteristics for a relatively long period of time, continuously and stably compensating for the vibration of the output shaft 511 and reducing the risk of performance degradation of the balancing assembly 513 due to particle wear. The high strength of the steel balls also makes them not easily deformed or damaged when subjected to a relatively large vibration impact force. In the case of a relatively large vibration of the output shaft 511, the steel balls can still effectively participate in the energy conversion process, ensuring the compensation effect of the vibration and maintaining the stable operation of the clothes treatment device 100.

[0156] In some embodiments, the total volume of the solid particles accounts for 10% to 90% of the volume of the accommodation space 5132a. Such a volume ratio of the solid particles can enable the distribution and flow state of the solid particles in the accommodation space 5132a to be optimal, so that the solid particles can generate heat energy through relatively full friction and collision when the output shaft 511 rotates, compensating for the vibration of the output shaft 511.

[0157] If the total volume of the solid particles accounts for less than 10% of the volume of the accommodation space 5132a, the collision opportunity between them is reduced, and thus the efficiency of converting vibration energy into heat energy is reduced, which cannot be effectively compensated when the output shaft 511 of the motor in the clothes treatment device 100 vibrates, resulting in a weakened damping effect; if the total volume of the solid particles accounts for more than 90% of the volume of the accommodation space 5132a, the movement space of the solid particles is not enough, and too many solid particles will hinder the flow of the balancing medium, and cannot achieve sufficient friction and collision between the particles, thereby reducing the energy conversion efficiency, which cannot be effectively compensated when the output shaft 511 of the motor in the clothes treatment device 100 vibrates, affecting the damping effect.

[0158] In some embodiments, in combination with Figures 4 to 6 , Figure 5 For Figure 4 The cross-sectional view at A-A in FIG. 13, the second balancing member 5132 is a ring structure, and the accommodation space 5132a is an annular space. The center of the ring structure is located on the axis of the output shaft 511. The ring structure can be uniformly distributed around the output shaft 511, and the balancing medium in the annular space can move uniformly when the output shaft 511 rotates, thereby more stably and uniformly compensating for the vibration generated by the output shaft 511.

[0159] In some embodiments, in combination with Figure 8 and Figure 10 The second balancing member 5132 further comprises a pushing member 51321, which is arranged in the accommodation space 5132a and fixedly connected to the inner wall of the second balancing member 5132. When the second balancing member 5132 rotates, the pushing member 51321 can apply a pushing force to the balancing medium in the direction of rotation, effectively enhancing the damping effect of the balancing assembly 513.

[0160] When the pushing member 51321 rotates with the second balancing member 5132, it applies a pushing force to the balancing medium in the direction of rotation. For liquid medium, the pushing force of the pushing member 51321 can provide a pushing force for the liquid medium to flow better in the accommodation space 5132a, and the liquid medium can more quickly adjust its own distribution so that when the rotation speed of the output shaft 511 exceeds the low-frequency resonance point of the suspension system, the mass center of the liquid medium after the system is eccentric from the mass center, reaches the position in the opposite direction more quickly, thereby reducing the eccentric equivalent more quickly and improving the damping effect.

[0161] For solid particle balancing medium, the pushing force of such pushing member 51321 can promote more frequent and more violent collisions between solid particles and between solid particles and the wall of the accommodation space 5132a, which means that more vibration energy can be converted into heat energy, thereby enhancing the ability to convert the vibration energy of the output shaft 511 into heat energy and effectively compensating for the vibration generated by the output shaft 511.

[0162] In some embodiments, combined with Figure 11 , Figure 11 for Figure 7 A cross-sectional view of the second balancing member 5132 shows that there are multiple pushing members 51321 distributed circumferentially along the second balancing member 5132. This ensures that during the rotation of the second balancing member 5132, each region inside the second balancing member 5132 can be pushed by the pushing members 51321 to exert a thrust on the balancing medium, and the thrust on the balancing medium is more uniform.

[0163] For the liquid medium, all the liquid media between the pushers 51321 can be subjected to the same thrust, which can adjust the distribution of the liquid medium more quickly. When the output shaft 511 rotates at high speed, the center of mass of the liquid medium and the center of mass of the system after eccentricity will reach a position with a phase difference of 180 degrees more quickly, thereby reducing the eccentricity equivalent and improving the vibration reduction effect more quickly. For the solid particles, all the solid particles between the pushers 51321 can be subjected to uniform thrust. The collision between solid particles or between solid particles and pushers 51321 and the inner wall will convert vibration energy into frictional heat energy more quickly and effectively. The uniform thrust makes the collision between particles more uniform in the circumferential direction, and will not result in excessively violent collisions in some parts while insufficient collisions in others. This will improve the overall energy conversion efficiency and more effectively convert the vibration energy of the output shaft 511 into heat energy and other forms of energy, thus enhancing the vibration reduction effect.

[0164] In some embodiments, combined with Figure 8 , Figure 10 and Figure 11 The pusher 51321 has a plate-like structure and extends radially along the second balancer 5132. The thickness direction of the plate-like structure extends circumferentially along the annular structure of the second balancer 5132. The plate-like pusher 51321 can more effectively apply thrust to the balancing medium. Due to its radial extension along the second balancer 5132, it can cover a larger area radially, increasing the contact area with the balancing medium. During the rotation of the output shaft 511, the pusher 51321 can more fully push the balancing medium to move, improving the compensation effect of the balancing assembly 513 on the vibration of the output shaft 511. Especially when the rotational speed of the output shaft 511 changes, it can more quickly adjust the distribution of the balancing medium to adapt to the vibration caused by the new eccentric state.

[0165] In some embodiments, combined with Figure 11The plurality of pushing members 51321 divide the accommodation space 5132a into a plurality of subspaces, the plurality of subspaces are arranged along the circumference of the second balancing member 5132, and the pushing member 51321 is provided with a communication hole 51322, and the communication hole 51322 is in communication with two adjacent subspaces along the circumference.

[0166] The liquid medium can flow freely in the plurality of subspaces through the communication hole 51322, and such partitioned flow can avoid disordered flow of the liquid in the accommodation space 5132a. The existence of the communication hole 51322 can ensure the ordered flow of the liquid between different subspaces along the circumference of the second balancing member 5132, and help to more accurately control the flow path of the liquid, so that the liquid can more effectively adjust its distribution to compensate for vibration according to the vibration of the output shaft 511.

[0167] In some embodiments, in combination with Figure 8 and Figure 9 , Figure 9 for Figure 8 The communication hole 51322 includes a first communication hole 51322a, which is arranged on the side of the pushing member 51321 close to the inner diameter of the balancing member.

[0168] In some embodiments, the communication hole 51322 further includes a second communication hole 51322b, which is arranged on the side of the pushing member 51321 close to the outer diameter of the balancing member.

[0169] When the output shaft 511 rotates at a low speed, the centrifugal force acting on the liquid medium is small, and the liquid medium adjusts its distribution in the accommodation space 5132a through the first communication hole 51322a. When the output shaft 511 rotates at a high speed, the centrifugal force acting on the liquid medium is large, and the liquid medium adjusts its distribution in the accommodation space 5132a through the second communication hole 51322b. The different positions of the first communication hole 51322a and the second communication hole 51322b will cause the liquid to form a specific flow direction in the accommodation space 5132a (i.e. from the inner diameter side of the balancing member to the outer diameter side of the balancing member). During the process of the output shaft 511 changing from low speed to high speed, the liquid tends to flow from the inner diameter side (where the first communication hole 51322a is located) to the outer diameter side (where the second communication hole 51322b is located) due to the centrifugal force. Such directional flow helps to more accurately adjust the distribution of the liquid in the accommodation space 5132a to adapt to the eccentric vibration of the output shaft 511, thereby effectively compensating for the vibration. Compared with a single communication hole 51322 or a design without a specific position communication hole 51322, such a design with different position communication holes 51322 can more accurately control the flow path of the liquid, and improve the response speed and compensation effect of the balancing assembly 513 on vibration.

[0170] In some embodiments, in combination Figure 9 The projection area of the first communication hole 51322a along the radial direction of the output shaft 511 is greater than the projection area of the second communication hole 51322b along the radial direction of the output shaft 511. When the output shaft 511 rotates at a low speed, the flow rate of the liquid medium passing through the first communication hole 51322a is also slow, and when the output shaft 511 rotates at a high speed, the flow rate of the liquid medium passing through the second communication hole 51322b is fast, so the area of the first communication hole 51322a is greater than the area of the second communication hole 51322b, thereby ensuring that the flow rates of the liquid medium passing through the first communication hole 51322a and the second communication hole 51322b are not greatly different, so that the liquid medium can flow in each sub-space through the communication hole 51322 at a similar flow rate regardless of whether the output shaft 511 rotates at a low speed or a high speed, thereby ensuring the response speed and compensation effect of the balancing assembly 513 on vibration.

[0171] In some embodiments, in combination Figure 9 The first communication hole 51322a has a first preset length along the axial direction of the output shaft 511 and has a first preset width along the radial direction of the output shaft 511.

[0172] In some embodiments, the second communication hole 51322b has a second preset length along the axial direction of the output shaft 511 and has a second preset width along the radial direction of the output shaft 511.

[0173] In some embodiments, the first preset length is greater than the second preset length, and the first preset width is equal to the second preset width. Since the first communication hole 51322a and the second communication hole 51322b are arranged along the radial direction of the second balancing member 5132 on the pusher 51321, the space in the radial direction is limited, while the space in the axial direction of the second balancing member 5132 is sufficient. Under the premise that the first preset width and the second preset width in the radial direction are the same, the first preset length is greater than the second preset length, so that the area of the first communication hole 51322a is greater than the area of the second communication hole 51322b, thereby ensuring that the liquid medium can flow in each sub-space through the communication hole 51322 at a similar flow rate regardless of whether the output shaft 511 rotates at a low speed or a high speed, thereby ensuring the response speed and compensation effect of the balancing assembly 513 on vibration.

[0174] In some embodiments, in combination Figure 8 and Figure 9The communication hole 51322 further comprises a third communication hole 51322c, which is arranged between the first communication hole 51322a and the second communication hole 51322b and penetrates the first communication hole 51322a and the second communication hole 51322b respectively. During the process that the output shaft 511 changes from low-speed rotation to high-speed rotation, the liquid medium flows from the first communication hole 51322a to the second communication hole 51322b, and the liquid medium can also flow between the subspaces through the third communication hole 51322c, which does not hinder the liquid medium from passing between the first communication hole 51322a and the second communication hole 51322b, thereby ensuring that the liquid medium can smoothly adjust its own distribution in the accommodation space 5132a.

[0175] In some embodiments, in combination with Figure 10 and Figure 18 , Figure 18 is Figure 10 FIG. 6 is a local enlarged view of C in FIG. 5, and the second balancing member 5132 comprises an inner ring wall 51323 arranged around the output shaft 511.

[0176] In some embodiments, the second balancing member 5132 further comprises the inner ring wall 51323, and an outer ring wall 51324 is arranged around the inner ring wall 51323, and the accommodation space 5132a is formed between the outer ring wall 51324 and the inner ring wall 51323.

[0177] In some embodiments, the pushing member 51321 is connected with the outer ring wall 51324, and the pushing member 51321 is arranged in a spaced manner with the inner ring wall 51323. When the balancing medium is solid particles, the solid particles can flow between the subspaces through the space between the pushing member 51321 and the inner ring wall 51323, so that the solid particles in each subspace can also collide with each other to generate heat energy, thereby more fully compensating the vibration generated by the output shaft 511.

[0178] In some embodiments, in combination with Figure 11 The second balancing member 5132 is in a plurality of ring structures, and the plurality of second balancing members 5132 are sequentially sleeved along the radial direction of the output shaft 511, and the innermost second balancing member 5132 is directly connected with the output shaft 511.

[0179] In this way, when only the second balance member 5132 is arranged on the output shaft 511, the limited space in the housing 1 is effectively utilized under the premise of ensuring the annular structure of the second balance member 5132, so that the outermost second balance ring can be fixed on the output shaft 511, and each second balance member 5132 can compensate the vibration. When the output shaft 511 rotates at high speed, the multiple second balance members 5132 work together to better suppress the larger vibration generated during high-speed rotation, thereby improving the stability of the entire clothes treatment device 100.

[0180] Moreover, if one of the balance members fails (for example, the internal balance medium leaks or the structure is damaged), the other balance members can still compensate for the vibration, thereby reducing the risk of serious vibration problems of the entire clothes treatment device 100 caused by the failure of a single balance member, improving the reliability and stability of the device, prolonging the service life of the device, and facilitating maintenance and repair.

[0181] In some embodiments, in combination with Figure 11 The second balance member 5132 further includes multiple separation rings 51325, the multiple separation rings 51325 are arranged in the accommodation space 5132a, the centers of the multiple separation rings 51325 are located on the axis of the output shaft 511, the multiple separation rings 51325 are sequentially arranged along the radial direction of the output shaft 511, and adjacent two separation rings 51325 are arranged at intervals to separate the accommodation space 5132a into multiple annular spaces, and the multiple annular spaces are respectively filled with balance medium.

[0182] In this way, the second balance member 5132 has an integrated structure, which is more compact and simple in design, reduces the cumbersome steps in the installation process, reduces the probability of errors, significantly improves the construction efficiency, and reduces the number of parts. This not only simplifies the installation process, but also reduces the connection points between parts, thereby reducing the risk of failure caused by loose or damaged connection points. The flow range of the balance medium in each annular space is limited, so that the balance medium moves orderly in the respective annular space to compensate for the vibration, thereby enhancing the stability of the entire balance assembly 513.

[0183] It can be understood that, taking the second balance member 5132 with three annular spaces or the three second balance members 5132 working together (three-cavity balance member) as an example, the vibration compensation effect of the second balance member 5132 with only one annular space (single-cavity balance member) on the output shaft is different from that of the first balance member 5131. The maximum amplitude of the second motor 51 and the pulley 22 caused by vibration is simulated and tested according to the three cases.

[0184] In some embodiments, the clothes treatment device 100 is a 110L platform, the motor is a fixed frequency AC motor, the constraint foot and the inner cross section are constrained, a force of 200N is applied to the motor shaft, and a comprehensive eccentric force such as an eccentric factor is represented. The output shaft 511 is in a high-speed rotating motion state, the second balance piece 5132 and the output shaft 511 are eccentric in phase by 180 degrees, the second balance piece 5132 only has one annular space and is filled with brine with the same volume ratio, the offset amount of the center of mass position of the second balance piece 5132 is set to be 0.5mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, and 4.0mm in sequence, and the maximum amplitude of the second motor 51 and the pulley 22 due to vibration is obtained. At the same time, for comparison and analysis, the center of mass offset of the balance piece is set to be 4.0mm, the single-cavity balance piece and the three-cavity balance piece are filled with brine, the maximum amplitude of the second motor 51 and the pulley 22 due to vibration is simulated, and the working conditions of the three balance pieces are analyzed. According to the above two simulation experiments, Table 2 is obtained.

[0185]

[0186] Table 2

[0187] According to Table 2, the change trend graph of the maximum amplitude corresponding to the offset amount of the single-cavity balance piece can be drawn respectively (as shown in Figure 19 , and the change trend graph of the maximum amplitude corresponding to the type of the balance piece when the offset amount of the balance piece is 4mm (as shown in Figure 20 ).

[0188] According to Table 2, Figure 19 and Figure 20 , only the salt water offset aggregation effect in the second balance piece 5132 is considered, and with the high-speed rotation of the output shaft 511, the balance force generated by the second balance piece 5132 can reduce the maximum amplitude of the second motor 51 and the pulley 22.

[0189] As can be seen from Figure 19 , with the increase of the offset amount of the center of mass position of the same single-cavity balance piece, the overall maximum amplitude of the second motor 51 and the maximum amplitude of the pulley 22 gradually decrease. For the same balance piece, the center of mass position of the balance piece is eccentric in phase with the output shaft 511 by 180 degrees, the greater the offset amount of the center of mass position, the smaller the amplitude of the second motor 51 and the amplitude of the pulley 22, the better the compensation effect on vibration, and the less likely the transmission belt 21 to produce relative displacement or even fall off on the pulley 22 due to vibration.

[0190] As can be seen from Figure 20It can be seen that, for the first balancing member 5131, the single-cavity balancing member (the second balancing member 5132 containing salt water inside), and the three-cavity balancing member (the second balancing member 5132 containing salt water inside) with the same outer diameter and the same offset amount of 4 mm of the center of mass, the maximum amplitude of the second motor 51 with the first balancing member 5131 is greater than that of the second motor 51 with the single-cavity balancing member, and the maximum amplitude of the second motor 51 with the single-cavity balancing member is greater than that of the second motor 51 with the three-cavity balancing member. Correspondingly, the maximum amplitude of the pulley 22 on the output shaft 511 with the first balancing member 5131 is greater than that of the pulley 22 on the output shaft 511 with the single-cavity balancing member, and the maximum amplitude of the pulley 22 on the output shaft 511 with the single-cavity balancing member is greater than that of the pulley 22 on the output shaft 511 with the three-cavity balancing member. Therefore, under a certain offset amount, the vibration compensation effect of the first balancing member 5131, the single-cavity balancing member, and the three-cavity balancing member increases in turn, and the three-cavity balancing member has the best vibration compensation effect, and the possibility of the transmission belt 21 generating relative displacement on the pulley 22 or even falling off due to vibration is the smallest, which more effectively ensures the stability of the clothes treatment device 100.

[0191] In some embodiments, the first balancing member 5131 and the second balancing member 5132 are connected by a welding process. Figure 12 , Figure 12 FIG. 1 is a structural schematic diagram of the first balancing member 5131 and the second balancing member 5132 disclosed in the embodiments of the present application. The first balancing member 5131 is connected to the output shaft 511, and the second balancing member 5132 is connected to the side of the first balancing member 5131 along the axial direction.

[0192] Since the second balancing member 5132 is a hollow structure and cannot be directly fixed to the output shaft 511, the second balancing member 5132 is connected to the first balancing member 5131 to form a more stable structure. During the operation of the clothes treatment device 100, especially during high-speed rotation or load changes, this connection method can enhance the overall stability of the balancing assembly 513. This design can compensate for the vibration of the output shaft 511 at different axial positions, and the two balancing members act simultaneously to compensate for the vibration, making the vibration compensation effect better and reducing the possibility of the transmission belt 21 generating relative displacement on the pulley 22 or even falling off due to vibration to a greater extent.

[0193] In some embodiments, the second balancing member 5132 is connected to the first balancing member 5131 by a welding process.

[0194] The cladding process is a common metal surface repair and protection technology. By melting metal powder or wire and cladding it to the damaged part, the performance of the metal structure is repaired and enhanced. It is widely used in industrial manufacturing and maintenance, and needs to go through the processes of cleaning and pretreating the surface, selecting appropriate cladding equipment and related parameters, cladding operation, polishing and grinding, coating, etc. Compared with traditional welding methods, the cladding process does not require a large amount of heat input, can effectively reduce thermal deformation and residual stress, reduce the influence on the base material, has good adhesive strength, and can provide good wear resistance, corrosion resistance and high temperature resistance.

[0196] In some embodiments, in combination Figure 13 , Figure 13 A structural schematic view of the connecting bracket 5133 disclosed in the embodiments of the present application is shown in FIG. 13. The balancing assembly 513 further comprises a connecting bracket 5133, which is connected to the output shaft 511, and the second balancing member 5132 is connected to the connecting bracket 5133.

[0197] This connection mode enables the second balancing member 5132 to maintain a stable positional relationship when the output shaft 511 rotates. The connecting bracket 5133 provides a reliable connection basis for the second balancing member 5132, preventing the second balancing member 5132 from shifting during operation and ensuring the stability of the entire balancing assembly 513 structure.

[0198] The presence of the connecting bracket 5133 can effectively transmit torque, enabling the second balancing member 5132 to work in coordination with the output shaft 511, and also reducing the shaking of the second balancing member 5132 caused by vibration through the support and connection of the connecting bracket 5133 when the output shaft 511 vibrates, thereby improving the stability of the entire balancing assembly 513.

[0199] In some embodiments, in combination Figure 13 The connecting bracket 5133 is a ring-shaped bracket, which is sleeved on the output shaft 511, and the second balancing member 5132 has a ring structure, which is sleeved on the outer periphery of the ring-shaped bracket.

[0200] The annular support is arranged on the output shaft 511 to provide a stable support structure for the second balancing member 5132, which ensures that the annular support and the annular structure of the second balancing member 5132 can better match, so that the connection between the second balancing member 5132 and the output shaft 511 is more stable when the output shaft 511 rotates, thereby ensuring the stability of the balancing assembly 513.

[0201] In some embodiments, in combination Figure 13 The connecting support 5133 includes a sleeve 51331 arranged on the output shaft 511 and capable of transmitting torque between the sleeve 51331 and the output shaft 511.

[0202] In some embodiments, the connecting support 5133 further includes a support ring 51332 arranged around the outer periphery of the sleeve 51331, and the support ring 51332 is coaxially arranged with the sleeve 51331, and the second balancing member 5132 is arranged on the outer peripheral wall of the support ring 51332.

[0203] In some embodiments, the connecting support 5133 further includes a support rib 51333 connected between the sleeve 51331 and the support ring 51332.

[0204] The sleeve 51331 is arranged on the output shaft 511 and can transmit torque, which ensures reliable power transmission between the connecting support 5133 and the output shaft 511, enhances the stability of the connecting support 5133 on the output shaft 511, prevents the connecting support 5133 from sliding or deviating relative to the output shaft 511, and thereby improves the structural stability of the entire balancing assembly 513. The support ring 51332 is arranged around the outer periphery of the sleeve 51331 and coaxially arranged with the sleeve 51331, which further enhances the integrity of the connecting support 5133, and the coaxial arrangement makes the force transmission more uniform, reducing the additional stress caused by eccentricity. When the output shaft 511 rotates at high speed, the design of the support rib 51333 can effectively prevent the connecting support 5133 from deforming or being damaged. The support ring 51332 provides a matching outer peripheral wall for the sleeve of the second balancing member 5132, so that the second balancing member 5132 can be stably installed on the connecting support 5133, which helps to improve the compensation effect of the balancing assembly 513 on the vibration of the output shaft 511.

[0205] In some embodiments, in combination Figure 13 The support rib 51333 is a plurality of support ribs, each support rib 51333 extends in the radial direction of the output shaft 511, and the plurality of support ribs 51333 are distributed in the circumferential direction of the output shaft 511, and the connecting line of the two ends of each support rib 51333 in the axial direction of the output shaft 511 passes through the axis of the output shaft 511.

[0206] The uniform distribution of the support ribs 51333 can evenly distribute the force on the connecting bracket 5133 in the circumferential direction. During the operation of the clothes treatment device 100, the connecting bracket 5133 needs to bear forces from multiple aspects, such as the gravity of the second balancing member 5132, the centrifugal force, and the impact force due to the vibration of the output shaft 511, etc. The uniformly distributed support ribs 51333 ensure that no local area bears excessive force, thereby avoiding the risk of damage to the connecting bracket 5133 due to local stress concentration, which helps to improve the overall structural strength and stability of the connecting bracket 5133 and prolong its service life.

[0207] In some embodiments, the connecting bracket 5133 is made of a hard material. The connecting bracket 5133 made of a hard material can provide better structural stability, ensuring that the connecting bracket 5133 can bear the corresponding force and vibration during the rotation of the output shaft 511, reducing the possibility of deformation of the connecting bracket 5133 during long-term use, and maintaining the stability of the overall structure of the balancing assembly 513.

[0208] In some embodiments, the connecting bracket 5133 is a plastic piece. Plastic materials generally have a lighter mass, which helps to reduce the overall weight of the clothes treatment device 100. Plastic materials also have good corrosion resistance and can resist the erosion of chemicals and moisture that may be encountered in daily use, thereby prolonging the service life of the connecting bracket 5133. Plastic materials can be molded into various complex shapes through molding processes such as injection molding, which provides greater flexibility for the design of the connecting bracket 5133. In addition, plastic materials generally have lower costs, and the use of plastic connecting brackets 5133 can reduce production costs, thereby reducing product prices and improving market competitiveness.

[0209] In some embodiments, the first balancing member 5131 is made of metal and the second balancing member 5132 is made of rubber.

[0210] The metal first balancing member 5131 generally has a higher density and rigidity, which can provide stable mass distribution and help compensate for vibration during the rotation of the output shaft 511. The rubber second balancing member 5132 has good elasticity and damping characteristics, which can absorb and dissipate vibration energy, further enhancing the balancing effect. The combination of the two can take advantage of their respective strengths in different vibration frequency ranges, improving overall balancing performance. In addition, while meeting performance requirements, material costs and manufacturing process feasibility are considered. This combination is more economically advantageous than a single-material balancing assembly 513, and it is also easier to produce and manufacture.

[0211] In some embodiments, the connecting bracket 5133 is made of a hard material. The connecting bracket 5133 made of a hard material can provide better structural stability, ensuring that the connecting bracket 5133 can bear the corresponding force and vibration during the rotation of the output shaft 511, reducing the possibility of deformation of the connecting bracket 5133 during long-term use, and maintaining the stability of the overall structure of the balancing assembly 513. Figure 7 and Figure 14 , Figure 7Another structural schematic view of the second balancing member 5132 (including the output shaft 511) disclosed in the embodiments of the present application is shown in the following, Figure 14 for Figure 7 the exploded view, the second motor 51 further comprises a limiting portion 5111, which is arranged on the output shaft 511 and used to limit the movement of the first balancing member 5131 along the circumference of the output shaft 511.

[0212] In some embodiments, the second motor 51 further comprises a matching portion 5112, which is arranged on the inner hole wall of the first balancing member 5131, and the matching portion 5112 cooperates with the limiting portion 5111 to enable the output shaft 511 to drive the first balancing member 5131 to rotate, so that the first balancing member 5131 can compensate for the vibration generated by the output shaft 511 during the rotation of the output shaft 511, effectively reducing the noise caused by the vibration, and reducing the possibility of relative displacement or even falling of the transmission belt 21 on the belt pulley 22 due to vibration, thereby prolonging the service life of the equipment and reducing maintenance and replacement costs. In this way, the output shaft can drive the first balancing member to rotate without adding other parts, simplifying the assembly process.

[0213] In some embodiments, in combination with Figure 7 and Figure 14 , the limiting portion 5111 is a flat portion formed on the outer circumferential surface of the output shaft 511, and the matching portion 5112 is a flat portion formed on the inner hole wall of the first balancing member 5131, and the flat portion is in contact with the flat portion to prevent the first balancing member 5131 from rotating relative to the output shaft 511. Among them, the flat portion usually refers to a flat part on the shaft workpiece, which is different from the circular cross section of the shaft, and it is flat. Flat parts are very common in mechanical processing, especially on shaft parts that need to be connected or transmitted with other parts. For example, on some transmission shafts, the flat portion can be used for key connection with other parts, or used as a positioning surface.

[0214] This structure ensures the effective transmission of power from the output shaft 511 to the first balancing member 5131, avoids energy loss caused by relative rotation, and makes the structure of the entire drive assembly 5 more compact and reliable. In the operation of the clothes treatment device 100, the balancing assembly 513 can work cooperatively with the output shaft 511 to accurately compensate for the vibration generated by the output shaft 511.

[0215] In some embodiments, in combination with Figure 4 and Figure 5The second motor 51 further comprises a motor shell 512, and the output shaft 511 penetrates through the motor shell 512. The output shaft 511 comprises a first end 511a and a second end 511b, and the first end 511a and the second end 511b respectively extend out of two opposite side walls of the motor shell 512. The first end 511a is in transmission connection with the roller 2, and the balancing assembly 513 is arranged at the second end 511b.

[0216] The two ends of the output shaft 511 extend out of the motor shell 512, and the balancing assembly 513 is additionally arranged at the second end 511b, so that the forces on the two ends of the output shaft 511 are more balanced when the output shaft 511 rotates. The balancing assembly 513 can balance the center of gravity of the output shaft 511, further reduces the vibration of the output shaft 511, and improves the stability of the driving assembly 5.

[0217] In some embodiments, in combination with Figure 7 and Figure 14 The second motor 51 further comprises an axial positioning structure 514 arranged between the balancing assembly 513 and the output shaft 511 to prevent the balancing assembly 513 from moving axially relative to the output shaft 511.

[0218] The axial positioning structure 514 can ensure that the position of the balancing assembly 513 on the output shaft 511 is fixed, preventing displacement in the axial direction. Especially when the output shaft 511 rotates at high speed, the axial positioning structure 514 can reduce the instability of the compensation vibration effect caused by the movement of the balancing assembly 513, thereby improving the stability and reliability of the entire driving assembly 5.

[0219] In some embodiments, in combination with Figure 7 and Figure 14 The axial positioning structure 514 comprises a shaft shoulder 5141 arranged on the output shaft 511.

[0220] In some embodiments, the axial positioning structure 514 further comprises a stopper 5142 arranged on the output shaft 511 in a detachable manner, and the balancing assembly 513 is arranged between the shaft shoulder 5141 and the stopper 5142.

[0221] The shaft shoulder 5141 is generally where the shaft diameter changes, forming a stepped shape. It can be a portion of the shaft where the diameter suddenly increases or decreases during machining, such as turning. In this embodiment, the output shaft 511 is machined to have a portion where the diameter suddenly decreases to accommodate the balancing assembly 513, so that one side of the balancing assembly 513 abuts the larger-diameter side in the axial direction. The other side of the balancing assembly 513 abuts the stopper 5142, and the shaft shoulder 5141 cooperates with the stopper 5142 to provide precise axial positioning of the balancing assembly 513. This allows the balancing assembly 513 to be accurately installed at a predetermined position on the output shaft 511, ensuring that it properly compensates for vibrations during rotation of the output shaft 511. Moreover, by flexibly removing the stopper 5142, the balancing assembly 513 can be easily removed for maintenance or replacement of damaged components (such as the stopper 5142, the balancing assembly 513, etc.).

[0222] In some embodiments, the stopper 5142 can be a nut that is threadedly connected to the shaft end of the output shaft 511. The nut is a common and standardized fastener that is easy to install and remove, facilitating regular maintenance or replacement of damaged components (such as the stopper 5142, the balancing assembly 513, etc.). The nut has good fastening performance and cooperates with the shaft shoulder 5141 to provide reliable axial positioning, preventing the balancing assembly 513 from shifting axially during operation.

[0223] In some embodiments, in combination with Figure 4 The balancing assembly 513 includes a first balancing member 5131, which is disposed on the output shaft 511.

[0224] In some embodiments, the balancing assembly 513 further includes an absorption member (not shown in the figure), which is disposed on the output shaft 511. The absorption member can be made of sound-absorbing material and / or water-absorbing material, i.e., it can be made of sound-absorbing material, water-absorbing material, or both.

[0225] The addition of the first balancing member 5131 to the output shaft 511 of the motor effectively reduces vibrations. The addition of the absorption member, which is made of sound-absorbing material, can absorb the noise generated by the second motor 51, further reducing the noise of the entire machine. The absorption member, which is made of water-absorbing material, can absorb the liquid water condensed from the water vapor around the second motor 51 and can throw off the absorbed water during high-speed rotation of the output shaft 511, improving the collection efficiency of the condensed water.

[0226] In some embodiments, the absorption member is made of porous material.

[0227] The porous material has good sound absorption performance, which can effectively absorb the noise generated during the operation of the device, providing a more quiet use environment. This is particularly important for laundry treatment devices 100 in a home environment, as users generally want to be undisturbed by noise when using these devices.

[0228] The porous material can also absorb moisture, maintaining a dry environment inside the device, thereby improving the performance and lifespan of the device. By reducing noise and absorbing moisture, the absorbing member of porous material can effectively improve the stability and safety of the drive assembly 5.

[0229] In some embodiments, the material of the absorbing member includes sponge, polyurethane foam, or foam rubber.

[0230] When the absorbing member is a sponge, the sponge is a porous material that can effectively absorb sound waves and reduce noise propagation. The sponge can also absorb a large amount of moisture, which is useful for absorbing moisture around the second motor 51 and maintaining a dry working environment. In addition, the elasticity and porosity of the sponge also provide a certain damping effect. When the output shaft 511 vibrates and generates a certain impact, the sponge can be compressed to reduce the impact force. When the absorbing member is polyurethane foam, the polyurethane foam has excellent sound absorption performance and can effectively absorb and isolate noise. The elasticity and plasticity of the polyurethane foam make it a good damping and cushioning material, protecting the first balancing member 5131 from impact and vibration. When the absorbing member is foam rubber, the porous structure of the foam rubber provides good sound absorption and insulation effects. The foam rubber also has elasticity and plasticity, which can achieve good damping effects.

[0231] In some embodiments, the absorbing member has a ring structure. The ring structure allows the absorbing member to be evenly distributed on the output shaft 511, so that the sound absorption and / or water absorption effects of the absorbing member are the same in the circumferential direction of the output shaft 511. The ring structure ensures that the absorbing member remains balanced during rotation, which helps to reduce displacement and vibration caused by uneven stress on the absorbing member, thereby reducing noise and improving the stability of the device. The ring structure can uniformly increase the contact area between the absorbing member and air or moisture, which helps to improve the efficiency of the absorbing member in absorbing noise and moisture, thereby improving the overall care effect.

[0232] In some embodiments, in combination Figure 4 The absorbing member and the first balancing member 5131 are arranged in an axial direction, and the absorbing member is connected to the first balancing member 5131. Since the absorbing member is flexible and cannot be directly fixed to the output shaft 511, the absorbing member is fixed to the first balancing member 5131, which has a larger area of contact, forming a more stable structure. This connection method can enhance the overall stability of the balancing assembly 513 during the operation of the laundry treatment device 100, especially during high-speed rotation or load changes.

[0233] The absorbing member is attached to the first balancing member 5131 in the axial direction, so that the absorbing member has better noise absorption effect, and can effectively absorb the noise generated by the first balancing member 5131 in the process of compensating the vibration on the premise that it can absorb the noise generated by the output shaft 511. In addition, the first balancing member 5131 provides a relatively stable mounting platform for the fixation of the absorbing member. When the output shaft 511 rotates at high speed, the absorbing member is not easy to fall off from the output shaft 511 due to the centrifugal force.

[0234] In some embodiments, when the absorbing member is made of water-absorbing material, the output shaft 511 rotates at high speed, and the water absorbed in the absorbing member is thrown out. The water can flow along the inner wall of the base of the clothes treatment device 100 to the water collecting groove (not shown in the figure), and then be pumped into the water box (not shown in the figure) by the water pump.

[0235] During the operation of the clothes treatment device 100, the absorbing member can absorb a large amount of water. When the output shaft 511 rotates at high speed, the water in the absorbing member is thrown out due to the centrifugal force. The setting of the water collecting groove prevents the water from flowing or accumulating randomly in the device. The water collecting groove can collect the water thrown out by the absorbing member in time, avoiding the accumulation of water on other parts in the device, thereby reducing the problems such as rust and corrosion of the parts caused by water.

[0236] For the clothes treatment device 100 containing electrical elements, such as the compressor 6 and fan motor in the heat supply system 4, a dry environment is an important condition to ensure the normal operation and electrical safety. The presence of water can cause electrical faults such as short circuit. The water collecting groove maintains a dry environment in the device by collecting water, which helps to ensure the safe operation of electrical elements.

[0237] In addition, if the absorbing member absorbs too much water and cannot discharge the water in time, its absorption capacity will decrease. The water collecting groove collects the water thrown out in time, so that the absorbing member can maintain good absorption performance. Whether it is the absorption of water or the absorption of noise, the effect can be maintained. The absorbing member in a long-term wet state can affect the performance and structural integrity of the material. By discharging the water in time through the water collecting groove, the absorbing member can work in a relatively dry state, reducing the problems such as aging and deformation of the material caused by long-term wetness, thereby prolonging the service life of the absorbing member.

[0238] In some embodiments, in combination Figure 15 , Figure 15 The schematic view of the positions of the compressor 6, the second fan 5134 and the motor is disclosed in the embodiments of the present application. The clothes treatment device 100 further comprises a compressor 6, which is arranged on one side of the second motor 51.

[0239] The compressor 6 compresses the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas, and the high-temperature and high-pressure refrigerant gas enters the condenser. In the condenser, the refrigerant gas releases heat, which is used to heat air. The heated drying gas is sent into the drum 2 of the clothes treatment device 100 and contacts the wet clothes, so that the water in the clothes evaporates into water vapor. The air containing the water vapor is guided to the evaporator. The refrigerant in the evaporator absorbs the heat in the air, so that the water vapor condenses into liquid water, thereby achieving dehumidification. The dehumidified air is again sent into the compressor 6 to start a new cycle until the clothes are dried.

[0240] In some embodiments, the fan includes a first fan corresponding to the air duct assembly 3. The first fan is driven to rotate by the first motor. The first fan is used to send the drying gas into the air duct assembly 3 and make the drying gas pass through the air duct assembly 3 into the drying cavity.

[0241] In some embodiments, the clothes treatment device 100 further includes a second fan 5134 arranged on the output shaft 511 opposite the compressor 6. When the output shaft 511 of the second motor 51 rotates, the second fan 5134 can be driven to rotate to deliver cooling air to the compressor 6.

[0242] During the operation of the compressor 6, a large amount of heat is generated. Originally, a refrigeration fan is arranged on the side of the compressor 6 away from the second motor 51 to cool the compressor 6. In this embodiment, the refrigeration fan is cancelled, and the compressor 6 is moved away from the second motor 51. A fan is added at the shaft end of the output shaft 511 to cool the compressor 6. In this way, the cooling of the compressor 6 is ensured, and the vibration of the output shaft 511 is compensated.

[0243] In some embodiments, in combination with Figure 16 , Figure 16 The structure of the second fan 5134 disclosed in the embodiments of the present application is shown in the schematic view. The second fan 5134 includes an inner ring fan 51341, which is an axial flow fan. The inner ring fan 51341 is connected to the output shaft 511. When the output shaft 511 rotates, the inner ring fan 51341 can rotate with it.

[0244] In some embodiments, the second fan 5134 further includes an outer ring fan 51342, which is an axial flow fan. The outer ring fan 51342 is connected to the outer periphery of the inner ring fan 51341. The air outlet directions of the inner ring fan 51341 and the outer ring fan 51342 are opposite, so that when the output shaft 511 rotates forward and reversely, the second fan 5134 can deliver cooling air to the compressor 6.

[0245] When the output shaft 511 is in one of the forward rotation state or the reverse rotation state, the inner ring fan 51341 delivers cooling air to the compressor 6, and the outer ring fan 51342 delivers cooling air to the second motor 51; when the output shaft 511 is in the other of the forward rotation state or the reverse rotation state, the outer ring fan 51342 delivers cooling air to the compressor 6, and the inner ring fan 51341 delivers cooling air to the second motor 51. Therefore, no matter whether the output shaft 511 is in the forward rotation state or the reverse rotation state, one of the inner ring fan 51341 and the outer ring fan 51342 can deliver cooling air to the compressor 6, and the other can deliver cooling air to the second motor 51.

[0246] The working principle of the axial fan is to generate airflow through the rotation of the impeller, which is usually composed of multiple blades. When the second motor 51 is started, the output shaft 511 drives the impeller to start rotating, causing the flow of air. The blades suck air from one side of the impeller and then discharge it to the other side through the hollow part in the center of the shaft. When the air is sucked in, it passes through the blades and is compressed, and then the air is pushed to the end of the blades, forming a high-speed airflow that is ejected through the end of the blades and then pushed along the axis direction of the impeller.

[0247] During the operation of the clothes treatment apparatus 100, the output shaft 511 can be rotated in the forward direction or the reverse direction due to different operating modes or fault handling, etc. Regardless of the rotation direction of the output shaft 511, the supply of cooling air to the compressor 6 can be ensured, so that the compressor 6 can continuously work in a suitable temperature range, improving the reliability and service life of the compressor 6 and making the entire device operate more stably. In addition, under the premise of always being able to deliver cooling air to the compressor 6, cooling air can also be delivered to the second motor 51 at all times, further ensuring the normal operation of the second motor 51.

[0248] In some embodiments, in combination with Figure 16 The second fan 5134 further includes a first connecting ring 51342a, which is arranged around the outer periphery of the inner ring fan 51341, and the inner surface of the first connecting ring 51342a is connected with the inner ring fan 51341, and the outer ring fan 51342 is connected to the outer surface of the first connecting ring 51342a.

[0249] The arrangement of the first connecting ring 51342a enhances the connection stability between the inner ring fan 51341 and the outer ring fan 51342. During the rotation of the fan, especially at high speed, this stable connection structure can reduce the shaking and deformation of the blades, thereby improving the overall stability and reliability of the fan.

[0250] In some embodiments, in combination with Figure 16The second fan 5134 further comprises a second connecting ring 51342b, which is arranged around the outer periphery of the outer ring fan 51342 and connected with the outer ring fan 51342.

[0251] The arrangement of the second connecting ring 51342b further enhances the structural strength of the outer ring fan 51342. During the rotation of the fan, especially when facing different working conditions and load changes, the second connecting ring 51342b can provide additional support force to reduce the risk of deformation and damage of the fan blades.

[0252] In some embodiments, in combination with Figure 16 The inner ring fan 51341 comprises a plurality of first fan blades (not shown in the figure), and the edge connected with the first connecting ring 51342a is a first edge 51341a.

[0253] In some embodiments, the outer ring fan 51342 comprises a plurality of second fan blades (not shown in the figure), and the edge connected with the second connecting ring 51342b is a second edge 51342c. The first edge 51341a and the second edge 51342c are both helical lines, and the directions of rotation of the first edge 51341a and the second edge 51342c are opposite.

[0254] In this way, the directions of rotation of the first edge 51341a and the second edge 51342c are opposite, so that when the output shaft 511 rotates, the air outlet directions of the inner ring fan 51341 and the outer ring fan 51342 are opposite. The second fan 5134 can deliver cooling air to the compressor 6 and the motor body regardless of the direction of rotation of the output shaft 511, which can increase the service life of the compressor and the second motor and improve the cooperative working efficiency of the entire device.

[0255] In some embodiments, in combination with Figure 4 、 Figure 15 and Figure 16 The second motor 51 comprises a motor shell 512, and the first end 511a of the output shaft 511 extends out of the motor shell 512 towards the side wall of the compressor 6. The first end 511a of the output shaft 511 is in driving connection with the drum 2, and the second fan 5134 is arranged at the first end 511a of the output shaft 511.

[0256] This layout enhances the integration between components. Since the second fan 5134 is arranged close to the compressor 6 and shares the same shaft end with the belt pulley 22, power can be transmitted from the output shaft 511 to the drum 2 while conveniently driving the second fan 5134 to rotate, thereby providing cooling air for the compressor 6 and improving the cooperative working efficiency of the entire device. In limited space, reasonable layout reduces the overall volume of the device and saves space resources.
