Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a clothing processing device. Background Technology

[0002] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The technological development trends for these products primarily focus on intelligentization, energy conservation and environmental protection, optimized user experience, and the application of new materials. Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.

[0003] As an important branch of household appliances, garment handling devices include dryers and washer-dryer combos. Dryers use circulating heat energy to heat and dry clothes. The drum holding the clothes rotates during the drying process to increase the contact area between the clothes and hot air, resulting in more even drying and improved efficiency. However, when the motor controls the rotation of the drum within the garment handling device, manufacturing tolerances cause the drum's geometric center to deviate from its original rotation center, resulting in circular runout. This periodic fluctuation of the drum excites the motor's output shaft, causing it to vibrate and generate noise. Utility Model Content

[0004] This application discloses a clothing processing device that can reduce the vibration of the motor output shaft.

[0005] To achieve the above objectives, this application discloses a garment processing device, comprising:

[0006] The housing includes a base, and the housing contains:

[0007] A roller is rotatably connected to the housing, and a drying chamber is formed inside the roller for holding clothes.

[0008] An air duct assembly, which is connected to the drying chamber, is used to guide drying gas into the drying chamber;

[0009] A heating system is provided to supply a heat source so that air exchanges heat with the heat source to form the drying gas;

[0010] A fan is provided corresponding to the air duct assembly. The fan is used to send the drying gas into the air duct assembly and to allow the drying gas to enter the drying chamber through the air duct assembly.

[0011] A drive assembly, disposed on the base, is connected to the roller and the fan respectively, and is configured to drive the roller and the fan to rotate. The drive assembly includes:

[0012] An output shaft is connected to the roller drive to drive the roller to rotate;

[0013] A balancing assembly, disposed on the output shaft, is configured to compensate for vibrations generated by the output shaft during rotation. The balancing assembly includes:

[0014] A second balancing component is disposed on the output shaft. The second balancing component has a receiving space containing a balancing medium.

[0015] Therefore, by adding a balancing component to the output shaft of the second motor, the balancing medium automatically adjusts its distribution within the accommodating space to compensate for the vibration generated by the output shaft when it rotates. By reducing the vibration of the output shaft, the noise caused by vibration can be effectively reduced. This further ensures the stability of the garment processing device's operation, helps extend the overall service life of the device, reduces the user's maintenance costs and the frequency of equipment replacement, and improves the device's cost-effectiveness.

[0016] As an optional implementation, the balancing medium includes a liquid medium.

[0017] Thus, the liquid medium exhibits good fluidity, and can rapidly adjust its distribution according to centrifugal force and vibration.

[0018] Due to the excitation force, the second balancing component 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 produces an offset y relative to the center of the second balancing component 5132. The excitation force F of the second balancing component is proportional to the rotational speed ω. The mass M of the second balancing component containing liquid and the eccentricity e caused by the excitation force, i.e., F = Mω, are the factors that affect the second balancing component 5132. 2 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 is large. As ω increases, F increases, and the offset y that causes the liquid response also increases and exceeds the eccentricity e generated by the second balancing component 5132. The centrifugal force Myω generated by y 2This 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.

[0019] As an optional implementation, the liquid medium includes brine and / or silicone oil.

[0020] Thus, brine, a solution formed by salt dissolved in water, can have its density adjusted by changing the salt concentration. In the balancing component, a suitable density helps to better achieve vibration compensation, while a higher density can provide greater inertial force to compensate for vibration when the output shaft rotates. Furthermore, brine is inexpensive to prepare, and the raw materials (salt and water) are readily available, reducing production costs. Silicone oil has high chemical stability and does not easily react with other substances. It will not deteriorate or lose its balancing effect due to reactions with the materials of the balancing component (such as container walls), which helps maintain the long-term stable operation of the garment processing device and reduces the decrease in vibration compensation capability caused by changes in the balancing medium. Silicone oil also has a certain degree of lubrication, which can reduce friction between internal components. When the output shaft rotates, the distribution of silicone oil in the second balancing component not only compensates for vibration but also reduces energy loss and noise caused by component friction, helping to improve the overall efficiency and service life of the equipment. In addition, silicone oil is a colorless, odorless, non-toxic, and non-volatile liquid. It can be used for a long time without causing harm to the human body.

[0021] As an optional implementation, the volume of the liquid medium occupies 30% to 50% of the volume of the accommodating space.

[0022] In this way, such a liquid volume ratio can optimize the distribution and flow of the liquid medium within the containment space, so that the liquid can adjust its position in time to compensate for the vibrations generated when the output shaft rotates.

[0023] As an optional implementation, the second balancing component is a ring structure, the accommodating space is an annular space, and the center of the second balancing component is located on the axis of the output shaft.

[0024] In this way, the annular structure can be evenly distributed around the output shaft, and the balance medium in the annular space can move evenly when the output shaft rotates, which can more stably and evenly compensate for the vibration generated by the output shaft.

[0025] As an optional implementation, the second balancing component further includes:

[0026] A pusher is disposed within the accommodating space. When the second balancing member rotates, the pusher can apply a thrust in the direction of rotation to the balancing medium.

[0027] In this way, the pusher can move the balancing medium within the accommodating space, effectively enhancing the vibration reduction effect of the balancing assembly.

[0028] As an optional implementation, there are multiple pushers, which are distributed circumferentially along the second balancing member.

[0029] This ensures that during the rotation of the second balancing component, each region inside the second balancing component can have a pushing component exerting a thrust on the balancing medium, and the thrust on the balancing medium is more uniform.

[0030] As an optional implementation, the pusher is a plate-like structure and extends radially along the second balancer.

[0031] Thus, the plate-shaped pusher can more effectively apply thrust to the balancing medium and cover a larger area in the radial direction, increasing the contact area with the balancing medium. During the rotation of the output shaft, the pusher can more fully drive the balancing medium to move, which can improve the compensation effect of the balancing assembly on the vibration of the output shaft. Especially when the output shaft speed changes, it can more quickly adjust the distribution of the balancing medium to adapt to the vibration caused by the new eccentric state.

[0032] As an optional implementation, the plurality of pushers divide the accommodating space into a plurality of subspaces, the plurality of subspaces being arranged circumferentially along the second balancing member, and each pusher having a connecting hole that connects two adjacent subspaces circumferentially.

[0033] In this way, the liquid medium can flow freely in multiple sub-spaces through the connecting holes. This zoned flow can avoid disordered flow of the liquid within the containment space. The presence of the connecting holes ensures that the liquid flows in an orderly manner along the circumference of the second balancing element between different sub-spaces, which helps to control the flow path of the liquid more precisely. This allows the liquid to adjust its distribution more effectively to compensate for vibration according to the vibration of the output shaft.

[0034] As an optional implementation, the connecting hole includes:

[0035] A first connecting hole is provided on the side of the pusher near the inner diameter of the balancer;

[0036] The second connecting hole is disposed on the side of the pusher near the outer diameter of the balancer.

[0037] Thus, when the output shaft rotates at a lower speed, the centrifugal force on the liquid medium is small, and the liquid medium adjusts its distribution within the accommodating space through the first connecting hole. When the output shaft rotates at a high speed, the centrifugal force on the liquid medium is larger, and the liquid medium adjusts its distribution within the accommodating space through the second connecting hole. This helps to more accurately adjust the distribution of the liquid within the accommodating space to adapt to the eccentric vibration of the output shaft, thereby effectively compensating for the vibration.

[0038] As an optional implementation, the projected area of ​​the first connecting hole along the radial direction of the output shaft is greater than the projected area of ​​the second connecting hole along the radial direction of the output shaft.

[0039] In this way, the flow rate of the liquid medium through the first connecting hole and the second connecting hole is not much different, so that the liquid medium can flow through the connecting holes in each subspace at a similar flow rate, regardless of whether the output shaft rotates at low speed or high speed, thus ensuring the response speed and compensation effect of the balancing component to vibration.

[0040] As an optional implementation, the first connecting hole has a first preset length along the axial direction of the output shaft, and the first connecting hole has a first preset width along the radial direction of the output shaft;

[0041] The second connecting hole has a second preset length along the axial direction of the output shaft, and the second connecting hole has a second preset width along the radial direction of the output shaft;

[0042] The first preset length is greater than the second preset length, and the first preset width is equal to the second preset width.

[0043] Thus, with limited space in the radial direction, it ensures that the liquid medium can flow through the connecting holes in each subspace at a similar flow rate, regardless of whether the output shaft rotates at low or high speed, thus guaranteeing the response speed and compensation effect of the balancing component to vibration.

[0044] As an optional implementation, the connecting hole further includes:

[0045] A third connecting hole is disposed between the first connecting hole and the second connecting hole, and the third connecting hole communicates with both the first connecting hole and the second connecting hole.

[0046] In this way, as the output shaft changes from low-speed rotation to high-speed rotation, the liquid medium flows from the first connecting hole to the second connecting hole, and the liquid medium can also flow between the subspaces through the third connecting hole. This does not obstruct the liquid medium from passing between the first and second connecting holes, ensuring that the liquid medium can smoothly adjust its distribution within the accommodating space.

[0047] As an optional implementation, there are multiple second balancing components, each of which is a ring structure, and the multiple second balancing components are sequentially nested along the radial direction of the output shaft.

[0048] Thus, when only the second balancing component is provided on the output shaft, the limited space inside the housing is effectively utilized while ensuring the ring structure of the second balancing component. This allows the outermost second balancing ring to be fixed on the output shaft, and each second balancing component can achieve the effect of compensating for vibration. When the output shaft rotates at high speed, multiple second balancing components work together to better suppress the large vibration generated during high-speed rotation and improve the stability of the entire garment processing device.

[0049] As an optional implementation, the second balancing component further includes:

[0050] Multiple partition rings are disposed within the accommodating space, with the centers of the multiple partition rings located on the axis of the output shaft. The multiple partition rings are arranged sequentially along the radial direction of the output shaft, with adjacent partition rings spaced apart, to divide the accommodating space into multiple annular spaces, each of which is filled with the balancing medium.

[0051] Thus, the second balancing component is a one-piece structure, designed to be simpler and more compact. This reduces cumbersome steps in the installation process, lowers the chance of errors, significantly improves construction efficiency, and reduces the number of parts. This not only simplifies the installation process but also reduces the number of connection points between components, thereby reducing the risk of failure due to loose or damaged connections. It also restricts the flow range of the balancing medium within each annular space, allowing the balancing medium to move orderly within its respective annular space to compensate for vibration and enhance the stability of the entire balancing assembly.

[0052] As an optional implementation, the balancing component further includes:

[0053] A first balancing component is disposed on the output shaft, and the center of mass of the first balancing component is located on the axis of the output shaft. A second balancing component is connected to one side of the first balancing component along the axial direction.

[0054] Thus, when the output shaft rotates, the rotational stability of the output shaft is effectively improved, thereby reducing the vibration generated by the output shaft. Since the second balancing component is a hollow structure, it is inconvenient to fix it directly to the output shaft. Therefore, the second balancing component is connected to the first balancing component, forming a more stable structure. During the operation of the garment processing device, especially during high-speed rotation or load changes, this connection method can enhance the overall stability of the balancing assembly. This design can compensate for the vibration of the output shaft at different axial positions. The two balancing components work simultaneously to compensate for vibration, making the vibration compensation effect better and reducing the vibration of the pulley to a greater extent. This effectively reduces the possibility of the transmission belt causing relative displacement or even detachment on the pulley due to vibration.

[0055] As an optional implementation, the driving component includes:

[0056] A first motor is connected to the fan and is used to drive the fan to rotate;

[0057] A second motor, connected to the roller via a transmission belt, is used to drive the roller to rotate. The second motor includes:

[0058] Motor housing;

[0059] The output shaft passes through the motor housing, and the output shaft includes a first end and a second end, which respectively extend out of two opposite side walls of the motor housing.

[0060] The first end is connected to the roller drive, and the balancing component is disposed at the second end.

[0061] In this way, the speed of the drum and the fan can be controlled separately. The fan can be controlled by the first motor alone, while the second motor only controls the rotation of the drum. The two ends of the output shaft extend out of the motor housing. A balancing component is added to the second end to make the forces on the two ends of the output shaft more balanced when rotating. This can balance the center of gravity of the output shaft, further reduce the vibration of the output shaft, and improve the stability of the drive component.

[0062] Compared with the prior art, the beneficial effects of this application are:

[0063] The garment processing device provided in this application embodiment adds a balancing component to the output shaft of the second motor. When the output shaft rotates, the balancing medium automatically adjusts its distribution within the accommodating space to compensate for the vibration generated by the output shaft. By reducing the vibration of the output shaft, the noise caused by vibration can be effectively reduced. This further ensures the operational stability of the garment processing device, helps extend the overall service life of the device, reduces user maintenance costs and the frequency of equipment replacement, and improves the cost-effectiveness of the device.

[0092] As an important branch of home appliances, garment handling devices include dryers and washer-dryer combos. Dryers use circulating heat energy to heat and dry clothes. The drum holding the clothes rotates during the drying process to increase the contact area between the clothes and hot air, resulting in more even drying and improved efficiency. When the motor controls the rotation of the drum within the garment handling device, due to manufacturing tolerances, the drum's geometric center may deviate from its original rotation center, causing circular runout. This periodic fluctuation of the drum excites the motor, causing it to vibrate and generate noise, resulting in a poor user experience.

[0093] Based on this, this application discloses a garment processing device, in which a balancing component is provided at the shaft end of the motor that controls the rotation of the drum to compensate for the vibration generated by the output shaft of the motor when it rotates, thereby reducing noise.

[0094] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0095] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the clothing processing device 100 disclosed in an embodiment of this application. The clothing processing device 100 can be a dryer or a washer-dryer combo.

[0096] The garment handling device 100 includes a housing 1, which serves as the external structure of the device and is typically made of metal or plastic. The housing 1 protects the internal components of the garment handling device 100 and provides robust support. The housing 1 is designed with durability, heat dissipation, noise control, safety, and maintainability in mind. The interior of the housing 1 is designed around a roller 2 to house and protect the roller 2 and other internal structures. The housing 1 includes a base for mounting some of the internal structures.

[0097] In some embodiments, please refer to Figure 2 , Figure 2 This is a schematic diagram of the internal structure of the garment processing apparatus 100 disclosed in this application. A roller 2 is provided inside the housing 1, and a drying chamber is formed within the roller 2. The drying chamber is used to hold garments. The roller 2, holding the garments, rotates during the drying process to increase the contact area between the garments and the hot air, resulting in more uniform drying and improved drying efficiency. The roller 2 is typically made of stainless steel to ensure strength and corrosion resistance. The inside of the roller 2 may have protrusions that increase the contact area with the wet garments, promoting the conduction of hot air to the garments, thereby improving drying efficiency.

[0098] In some embodiments, combined with Figure 2 The housing 1 is provided with a feeding port 1a, which is located on the axial direction of the roller 2 and corresponds to the roller 2, and is used to feed clothes into the roller 2.

[0099] In some embodiments, combined with Figure 3 , Figure 3This is a schematic diagram of the internal structure of the clothing handling device 100 (drum 2 omitted) disclosed in this application embodiment. The housing 1 contains an air duct assembly 3, which communicates with the drying chamber and guides drying gas into the chamber. The air duct design takes aerodynamics into account to optimize airflow path, reduce wind resistance, and improve the transmission efficiency of drying gas. A fan can be installed inside the air duct to generate power. Air guides can also be installed inside the air duct to guide airflow into the dryer drum, ensuring that the clothes can fully contact the drying gas.

[0100] In some embodiments, combined with Figure 3 The housing 1 is equipped with a heating system 4, which provides a heat source. It can be an 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 provide enough heat to ensure that the clothes can be dried in a short time.

[0101] In some embodiments, combined with Figure 3 A fan (not shown in the figure) is provided inside the housing 1. The fan is correspondingly arranged with the air duct assembly 3. The fan is used to send the drying gas into the air duct assembly 3 and to make the drying gas enter the drying chamber through the air duct assembly 3.

[0102] Clothes dryers mainly include heat pump dryers, condenser dryers, and exhaust dryers. Different types of dryers all have the above structures, but their drying principles are different.

[0103] Heat pump dryers typically operate on the principle of heat pump technology, using cyclical heat energy to heat and dry clothes. The working principle involves a heat pump circulation system (heating system 4) to achieve low-temperature drying. This system usually consists of a compressor 6, a condenser, a throttling valve, and an evaporator, filled with a suitable circulating refrigerant. During operation, the low-temperature, low-pressure refrigerant absorbs heat from the surrounding environment (such as inside the dryer) in the evaporator and evaporates into a gas. In this process, the refrigerant absorbs moisture from the clothes while its own temperature rises. Subsequently, the high-temperature refrigerant gas is drawn into and compressed by the compressor 6, increasing its temperature and pressure, transforming into a high-temperature, high-pressure gas. This high-temperature refrigerant gas (drying gas) then flows into the condenser, where it releases heat and transfers it to the air inside the dryer through the air duct assembly 3 (which connects to the drying chamber and guides the drying gas into the chamber). Simultaneously, the refrigerant itself condenses into a liquid state. The condensed liquid working fluid is depressurized through a throttling valve and enters the evaporator, where it absorbs more heat and re-evaporates into gas, completing the cycle. A fan drives the gas flow within the air duct assembly 3 to achieve this circulation. This cycle repeats continuously until the moisture in the clothes is completely evaporated, achieving a drying effect. The advantage of heat pump dryers lies in their high energy efficiency, as they recover heat from the environment for drying, rather than directly consuming electricity like traditional resistance heating dryers. Furthermore, heat pump dryers generate lower temperatures during operation, which is gentler on clothes, helping to protect clothing fibers and reducing the risk of shrinkage and damage.

[0104] Condenser dryers work on the principle of condensation technology to remove moisture from wet clothes. An internal heater (heating system 4) heats the air, producing dry, hot air. This hot air is blown into the dryer drum 2 by a fan, passing through the wet clothes and absorbing moisture. The humid hot air then flows through the condenser, where the cooling surfaces condense water vapor into droplets. These droplets are collected in a container inside the condenser or drained through a connected hose. The dried hot air, having lost its moisture after condensation, is reheated and recirculated into the drum 2 within the air duct assembly 3 to continue drying the clothes. The condensed moisture is discharged outside the dryer via a preset method (water tank or drain pipe).

[0105] An exhaust-type clothes dryer is a device that removes moisture from clothes by heating air and blowing it into the drum 2. The dryer is equipped with heating elements (heating system 4), usually electric heating wires, which heat the intake air. The heated air is then transported into the drum 2 of the dryer by a fan within the air duct assembly 3. The hot air passes through the clothes, absorbs the moisture from them, and flows with the hot air to the other end of the dryer. The hot air containing moisture is then discharged into the indoor or outdoor environment through the exhaust pipe.

[0106] Washer-dryer combos typically combine washing and drying functions in one appliance, and they can use different drying technologies to dry clothes. Heat pump dryers, due to their advantages such as low-temperature drying, energy efficiency, environmental friendliness, and gentleness on clothes, are suitable for families who prioritize drying quality. Condenser and ventilated dryers have relatively simple structures and low costs, making them suitable for users with limited budgets.

[0107] In some embodiments, combined with Figure 2 The housing 1 is also provided with a drive assembly 5, which is set on the base. The drive assembly 5 is connected to the roller 2 and the fan respectively. The drive assembly 5 can drive the roller 2 and the fan to rotate synchronously or separately. When the roller 2 and the fan are both set on the same motor, they rotate synchronously. When the roller 2 and the fan are controlled by two motors respectively, they rotate separately. This embodiment does not limit this.

[0108] In some embodiments, the drive component 5 includes a first motor (not shown) connected to the fan for driving the fan to rotate.

[0109] In some embodiments, the drive assembly 5 further includes a second motor 51, which is connected to the roller 2 for driving the roller 2 to rotate.

[0110] In some embodiments, combined with Figure 2 and Figure 4 , Figure 4 This is a schematic diagram of the structure of the second motor 51 (including pulley 22) disclosed in the embodiment of this application. The second motor 51 includes an output shaft 511, which is connected to the roller 2 via a transmission belt 21 to drive the roller 2 to rotate. Since the diameter of the roller 2 is much larger than the diameter of the output shaft 511, when the output shaft 511 rotates at high speed, the speed of the roller 2 is reduced by the belt, so that the clothes inside the roller 2 rotate at a slower speed, increasing the contact area between the clothes and the hot air, and making the drying more uniform.

[0111] It should be noted that the output shaft 511 typically has two states: low-speed rotation and high-speed rotation. Low speed usually refers to the motor's rotation speed during startup, while high speed usually refers to the output shaft 511's rotation speed exceeding the speed of the output shaft 511 when the suspension system resonates at low frequencies. These two rotational speeds are relative concepts, not specific speed ranges. Low-frequency resonance refers to the phenomenon where, during washing machine operation, the washing machine's vibration frequency matches its natural frequency, resulting in a significant increase in vibration amplitude.

[0112] In some embodiments, combined with Figure 2 and Figure 4The second motor 51 also includes a pulley 22, which is mounted on the output shaft 511 and is connected to the roller 2 via a transmission belt 21.

[0113] Since one end of the drive assembly 5 is connected to the roller 2 via pulley 22 and transmission belt 21, and the other end is connected to the fan, the roller 2 and the fan can only be adjusted synchronously when their speeds are adjusted. When it is desired to control the roller 2 to rotate rapidly, the speed of the output shaft 511 is increased, but the fan speed cannot be reduced simultaneously; the fan can only increase its speed synchronously with the output shaft 511 and the roller 2. To control the speeds of the roller 2 and the fan separately, the fan is controlled separately by the first motor, while the second motor 51 only controls the rotation of the roller 2. Furthermore, due to manufacturing and installation tolerances, the geometric center of the roller 2 may deviate from its original rotation center, causing the roller 2 to run out of rotation. This runout generates an excitation force on the second motor 51, causing the motor to vibrate and produce noise.

[0114] Therefore, a balancing component 513 is added to the output shaft 511 of the second motor 51 to compensate for the vibration generated by the output shaft 511 when it rotates. By reducing the vibration of the output shaft 511, the noise caused by vibration can be effectively reduced, improving the user experience of the garment processing device 100. In addition, since the output shaft 511 is connected to the roller 2 via the transmission belt 21, and the transmission belt 21 is connected to the output shaft 511 by the pulley 22 mounted on the output shaft 511, the vibration of the pulley 22 is reduced by setting the balancing component 513 to compensate for the vibration. This further reduces the possibility of the transmission belt 21 being displaced on the pulley 22 due to vibration, or even falling off. It also reduces the wear of the transmission belt 21 and the pulley 22 caused by vibration, further ensuring the stability of the garment processing device 100's operation, helping to extend the overall service life of the garment processing device 100, reducing the user's maintenance costs and the frequency of equipment replacement, and improving the cost-effectiveness of the device.

[0115] A balancing component 513 is disposed on the output shaft 511 and can rotate with the output shaft 511. The balancing component 513 can increase the moment of inertia of the output shaft 511 when the output shaft 511 rotates. In this way, while achieving independent control of the rotation of the fan and the drum 2, the increase in the moment of inertia helps to improve the stability of the rotation of the output shaft 511, thereby reducing the vibration that may be generated by the output shaft 511 during rotation, reducing the noise generated by the garment handling device 100 during operation, and preventing the transmission belt 21 from slipping or even falling off the pulley 22 due to vibration.

[0116] In some embodiments, combined with Figure 4The balancing assembly 513 includes a first balancing element 5131, which is disposed on the output shaft 511. Since the center of mass of the first balancing element 5131 is located on the axis of the output shaft 511, when the output shaft 511 rotates, it effectively improves the rotational stability of the output shaft 511, thereby reducing the vibration generated by the output shaft 511.

[0117] In some embodiments, combined with Figure 4 The first balancing component 5131 can be a ring-shaped structure with uniform mass distribution. The first balancing component 5131 is sleeved on the output shaft 511, with its center located on the axis of the output shaft 511. The ring-shaped structure makes the mass distribution of the first balancing component 5131 more uniform in the circumferential direction. When the output shaft 511 rotates, it ensures that the force on the first balancing component 5131 in the circumferential direction is more uniform, and the various parts on the circumference can generate a relatively uniform centrifugal force. Compared with irregular shapes, this is more conducive to maintaining rotational stability, can more accurately compensate for the vibration of the output shaft 511, reduce the vibration generated by the rotation of the output shaft 511, thereby reducing noise and reducing the possibility of displacement of the transmission belt 21 relative to the pulley 22.

[0118] In some embodiments, the second motor 51 is a fixed-frequency AC motor. Fixed-frequency AC motors have lower costs, thus reducing the overall cost of the device. Furthermore, fixed-frequency AC motors offer stable speed and reliable operation, ensuring the stability and efficiency of the workload, providing stable power output, and ensuring the normal operation of the device. Fixed-frequency AC motors have a relatively simple structure and efficient operating characteristics, and high energy conversion efficiency, which can save energy costs for the clothing processing device 100, which operates for extended periods. Their maintenance and repair costs are also relatively low, and their long service life reduces maintenance costs and downtime.

[0119] 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.

[0120]

[0121] Table 1

[0122] Table 1 can be used to draw the following diagram: Figure 17 The graph shown depicts the trend of the maximum amplitude corresponding to the mass of the first balancing component 5131 (the maximum amplitudes of the second motor 51 and 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.

[0123] In some embodiments, the mass of the first balancing component 5131 can be determined to be 150g to 400g based on the actual working conditions. And it can be seen from the following formula (1) that the greater the load on the roller 2, the greater the mass of the first balancing component 5131 required.

[0124]

[0125] Where m is the mass of the first balancing component 5131, M is the mass of the roller 2 when fully loaded, M = 10 kg, r3 is the outer diameter of the first balancing component 5131, k is the correlation coefficient, R1 is the radius of the roller 2, R2 is the radius of the pulley 22, L1 is the length of the roller, and L2 is the center distance between the roller 2 and the pulley 22.

[0126] The primary function of the first balancing component 5131 is to compensate for vibrations generated during the rotation of the output shaft 511. According to actual operational tests, if the mass is less than 150g, the amount of vibration compensation for the output shaft 511 is relatively small, and the vibration of the pulley 22 on the output shaft 511 remains quite noticeable. This may cause displacement of the transmission belt 21 on the pulley 22, thus affecting the stability and service life of the entire device. If the mass of the first balancing component 5131 exceeds 400g, its large size will cause interference with the inner wall of the base of the clothing processing device 100. Therefore, a first balancing component 5131 weighing between 150g and 400g can achieve a good vibration compensation effect within a limited installation space, effectively improving the rotational stability of the output shaft 511.

[0127] In some embodiments, the first balancing component 5131 is made of steel. Steel is a high-strength material capable of withstanding significant stress and deformation. Steel also has a high density, allowing for the manufacture of a first balancing component 5131 with a greater mass for the same volume, resulting in better vibration compensation. In the garment handling device 100, the first balancing component 5131 needs to compensate for vibrations generated when the output shaft 511 rotates. The steel material provides sufficient strength and durability, ensuring it will not be easily damaged during long-term use. Steel typically has a certain degree of corrosion resistance, extending the service life of the first balancing component 5131 and reducing the frequency of maintenance and replacement. Furthermore, choosing steel as the material for the first balancing component 5131 effectively controls production costs while ensuring product quality.

[0128] In some embodiments, the thickness of the first balancing component 5131 is 3mm to 7mm. If the thickness of the first balancing component 5131 is less than 3mm, it cannot provide sufficient strength and stability, is prone to deformation, and affects the service life of the device. Moreover, in order to ensure that the mass of the first balancing component 5131 is large enough, its outer diameter needs to be set larger. Since the second motor 51 is usually mounted on the base, which typically houses components such as the heating system 4 and the fan assembly of the air duct assembly 3, the base space is limited. An excessively large outer diameter of the first balancing component 5131 will interfere with the inner wall of the base. If the thickness of the first balancing component 5131 is greater than 7mm, it may also interfere with the inner wall of the base of the clothing handling device 100. Therefore, the thickness is set to 3mm to 7mm, so that the first balancing component 5131 can achieve a better vibration compensation effect while ensuring sufficient installation space for other components on the base, effectively improving the rotational stability of the output shaft 511.

[0129] Based on the above formula (1) and the following formula for moment of inertia (2), and combined with the actual working conditions, it can be concluded that when the outer diameter of the first balancing component 5131 is less than 60mm, the moment of inertia of the first balancing component 5131 is too small and cannot effectively compensate for the vibration of the output shaft 511. The vibration of the pulley 22 on the output shaft 511 is still quite obvious, and the transmission belt 21 will be displaced or even fall off on the pulley 22, thus affecting the stability and service life of the entire device. If the outer diameter of the first balancing component 5131 exceeds 100mm, the volume of the first balancing component 5131 is large. Since the second motor is usually set on the base, and other components (heating system 4 and fan assembly of air duct assembly 3, etc.) are usually also set on the base of the clothing processing device 100, the base space is limited, and the first balancing component 5131 will interfere with the inner wall of the base. Therefore, the first balancing component 5131 with an outer diameter of 60mm to 100mm can achieve a better vibration compensation effect under limited installation space, effectively improving the rotational stability of the output shaft 511.

[0130] I = mr3 2 (2)

[0131] Where I is the moment of inertia of the first balancing member 5131 when it rotates about the axis of the output shaft 511, m is the mass of the first balancing member 5131, and r3 is the outer diameter of the first balancing member 5131.

[0132] 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.

[0133] 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 produces 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 ω. The mass M of the second balancing member containing liquid and the eccentricity e caused by the excitation force, i.e., F = Mω, are the eccentricities of the second balancing member 5132. 2e. 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 is large. As ω increases, F increases, and the offset y that causes the liquid response also increases and exceeds the eccentricity e generated by the second balancing component 5132. The centrifugal force Myω generated by y 2 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.

[0134] 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.

[0135] In some embodiments, the liquid medium may be brine and / or silicone oil, i.e., brine or silicone oil or a mixture of brine and silicone oil.

[0136] In a first possible implementation, the brine is a solution formed by dissolving salt in water, the density of which can be adjusted by changing the salt concentration. In the balancing component 513, a suitable density (e.g., 1.0 g / cm³) is achieved. 3 -1.5g / cm 3 This helps to better achieve vibration compensation. Higher density can provide greater inertial force to compensate for vibration when the output shaft 511 rotates. Especially when dealing with vibrations generated at large amplitudes or high speeds, the density can be changed by adjusting the brine concentration, which enables the balancing component 513 to adapt more accurately to the operating state of the equipment. Moreover, the brine preparation cost is low and the raw materials (salt and water) are easy to obtain, reducing production costs.

[0137] In the second possible implementation, silicone oil has high chemical stability and does not easily react with other substances. Silicone oil will not deteriorate or lose its balancing effect due to reaction with the material of the balancing component 513 (such as the container wall). This helps to maintain the long-term stable operation of the clothing treatment device 100 and reduce the decrease in vibration compensation capability caused by changes in the balancing medium. Silicone oil also has a certain degree of lubrication, which can reduce friction between internal components. When the output shaft 511 rotates, the distribution of silicone oil in the second balancing component 5132 can not only compensate for vibration, but also reduce energy loss and noise caused by component friction, which helps to improve the overall efficiency and service life of the equipment. In addition, silicone oil is a colorless, odorless, non-toxic and non-volatile liquid that can be used for a long time without causing harm to the human body.

[0138] In a third possible implementation, the brine and silicone oil are mixed. This not only allows for the appropriate adjustment of the overall density of the balancing medium by using two liquids of different densities, thus improving the fluidity of the balancing medium, but also gives the balancing medium higher chemical stability, making its movement within the balancing component 513 smoother. This further enhances its ability to compensate for vibrations and relatively reduces the production cost of silicone oil as the balancing medium by mixing brine.

[0139] In some embodiments, the volume of the liquid medium occupies 30% to 50% of the volume of the accommodating space 5132a. This liquid volume ratio allows for optimal distribution and flow of the liquid medium within the accommodating space 5132a, enabling the liquid to adjust its position promptly and compensate for vibrations when the output shaft 511 rotates. If the liquid volume is too small, there will be too little balancing medium distributed within the accommodating space 5132a, which will not effectively compensate for vibrations, and the vibration reduction effect will be insignificant. That is, when the liquid volume is less than 30%, the liquid mass is insufficient, and the balancing medium cannot balance the vibration of the motor output shaft 511 within the clothing handling device 100. Conversely, if the liquid volume is too large, the liquid medium's internal range of motion will be too small, resulting in poor automatic adjustment of its center of mass position based on the eccentric position of the output shaft 511, leading to ineffective vibration compensation. That is, when the liquid volume is greater than 50%, the liquid's movement space is insufficient, and it cannot effectively compensate for the vibration of the motor output shaft 511 within the clothing handling device 100.

[0140] Preferably, the volume of the liquid medium occupies 40% of the volume of the accommodating space 5132a. While ensuring cost, the liquid medium with a volume ratio of 40% can be better distributed and flowed within the accommodating space 5132a. When the output shaft 511 rotates, the liquid can adjust its position in time to compensate for the resulting vibration.

[0141] In some embodiments, combined with Figure 10The equilibrium medium consists of multiple solid particles. Figure 10 This is a cross-sectional view of the second balancing member 5132 (including the output shaft 511) when the balancing medium is solid particles. When the output shaft 511 rotates, multiple solid particles can collide with each other, and the solid particles will also collide with the side wall of the second balancing member 5132, converting the vibration energy generated by the output shaft 511 into heat energy generated by the collision to compensate for the vibration generated by the output shaft 511.

[0142] In some embodiments, the solid particles include at least one of iron shot, lead pellets, or steel balls. The iron shot, lead pellets, and steel balls have relatively regular shapes (approximately spherical), which allows them to move smoothly within the accommodating space 5132a when the output shaft 511 rotates. Moreover, all three types of solid particles can generate heat through collisions, effectively compensating for vibrations.

[0143] In a first possible implementation, the solid particles are iron sand. Iron sand has a relatively high density, and when it collides with other particles or the sidewall of the second balancing element 5132, due to its relatively large mass, it can more effectively convert the vibration energy of the output shaft 511 into heat energy under the same velocity change, according to the law of conservation of energy. When the output shaft 511 generates a certain vibration velocity, the momentum change of the iron sand particles during collision is large, thus more fully absorbing and converting vibration energy, providing better compensation for the vibration of the output shaft 511. Moreover, the iron sand particles have a relatively irregular shape but are hard, and during long-term use, they are not easily worn or deformed, maintaining their distribution within the accommodating space 5132a, and continuously and stably converting vibration energy. As a relatively common and low-cost material, using iron sand as solid particles can effectively control production costs while meeting the functional requirements of vibration compensation for the output shaft 511.

[0144] In a second possible implementation, the solid particles are lead particles. Lead particles have a relatively high density, and when they collide with other particles or the sidewall of the second balancing component 5132, they can effectively absorb the vibration energy of the output shaft 511 and convert it into heat energy. Lead is relatively soft, a property that provides a certain damping effect during collisions. This slows down the collision speed between particles and between particles and the sidewall, making the energy conversion process smoother and reducing the impact on the structure of the balancing component 513 caused by violent collisions. This extends the service life of the balancing component 513 and also stably compensates for the vibration of the output shaft 511.

[0145] In a third possible implementation, the steel balls possess high hardness, making them resistant to wear during prolonged mutual collisions and impacts with the sidewalls. This allows the steel balls to maintain their shape and mass characteristics for an extended period, continuously and stably compensating for vibrations in the output shaft 511 and reducing the risk of performance degradation in the balancing component 513 due to particle wear. The high strength of the steel balls also prevents them from easily deforming or being damaged when subjected to significant vibrational impacts. Even under conditions of substantial vibration in the output shaft 511, the steel balls can still effectively participate in the energy conversion process, ensuring effective vibration compensation and maintaining the stable operation of the clothing handling device 100.

[0146] In some embodiments, the total volume of solid particles occupies 10% to 90% of the volume of the accommodating space 5132a. This volume ratio optimizes the distribution and flow of solid particles within the accommodating space 5132a, allowing for sufficient frictional collisions and heat generation from the solid particles when the output shaft 511 rotates, thus compensating for vibrations generated by the output shaft 511. If the total volume of solid particles occupies less than 10% of the volume of the accommodating space 5132a, the chances of collisions between them decrease, resulting in reduced efficiency in converting vibrational energy into heat. This fails to effectively compensate for vibrations in the output shaft 511 of the motor within the clothing processing device 100, leading to a weakened vibration damping effect. Conversely, if the total volume of solid particles occupies more than 90% of the volume of the accommodating space 5132a, the movement space for the solid particles is insufficient. Excessive solid particles hinder the flow of the balancing medium, preventing sufficient frictional collisions between particles and reducing energy conversion efficiency. This also fails to effectively compensate for vibrations in the output shaft 511 of the motor within the clothing processing device 100, affecting the vibration damping effect.

[0147] In some embodiments, combined with Figures 4 to 6 , Figure 5 for Figure 4 In the cross-sectional view at point AA, the second balancing element 5132 is a ring-shaped structure, and the accommodating space 5132a is an annular space. The center of the second balancing element 5132 is located on the axis of the output shaft 511. The annular structure can be evenly distributed around the circumference of the output shaft 511, and the balancing medium in the annular space can move evenly when the output shaft 511 rotates, which can more stably and evenly compensate for the vibration generated by the output shaft 511.

[0148] In some embodiments, combined with Figure 8 and Figure 10The second balancing component 5132 also includes a pushing component 51321. The pushing component 51321 is disposed within the accommodating space 5132a and fixedly connected to the inner wall of the second balancing component 5132. When the second balancing component 5132 rotates, the pushing component 51321 can apply a thrust along the rotation direction to the balancing medium, effectively enhancing the vibration reduction effect of the balancing assembly 513. When the pushing component 51321 rotates with the second balancing component 5132, it applies a thrust along the rotation direction to the balancing medium. For liquid media, the thrust of the pushing component 51321 provides thrust to the liquid media, allowing it to flow better within the accommodating space 5132a. The liquid media can adjust its distribution more quickly so that when the rotational speed of the output shaft 511 exceeds the low-frequency resonance point of the suspension system, the center of mass of the liquid media and the center of mass of the system after eccentricity reach a position with a phase difference of 180 degrees more quickly, thereby reducing the eccentricity equivalent more quickly and improving the vibration reduction effect. For a solid particle balancing medium, the thrust of this pusher 51321 will cause more frequent and more intense collisions between solid particles and between solid particles and the wall of the accommodating space 5132a. This 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.

[0149] In some embodiments, combined with Figure 11 , Figure 11 for Figure 7 A cross-sectional view of the second balancing member 5132 shows 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 within the member is subjected to thrust from the pushing members 51321, resulting in a more uniform thrust on the balancing medium. For the liquid medium, all pushing members 51321 experience the same thrust, allowing for faster adjustment of the liquid medium distribution. This enables the center of mass of the liquid medium to reach a 180-degree phase difference with the system's center of mass after eccentricity when the output shaft 511 rotates at high speed, thus reducing the eccentricity equivalent more quickly and improving vibration damping. For solid particles, all solid particles between each pusher 51321 can be subjected to uniform thrust. The collision between solid particles or the collision between solid particles and pushers 51321 and inner wall can 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 there will be no situation where the collision is too violent in some parts and the collision is insufficient in other parts. This improves the overall energy conversion efficiency and more effectively converts the vibration energy of the output shaft 511 into heat energy and other forms of energy, thus enhancing the vibration reduction effect.

[0150] 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.

[0151] In some embodiments, combined with Figure 11 Multiple pushers 51321 divide the accommodating space 5132a into multiple subspaces, which are arranged circumferentially along the second balancing member 5132. Each pusher 51321 is provided with a connecting hole 51322, which connects two adjacent subspaces circumferentially. The liquid medium can flow freely within the multiple subspaces through the connecting holes 51322. This partitioned flow can prevent disordered flow of liquid within the accommodating space 5132a. The presence of the connecting holes 51322 ensures that the liquid flows orderly along the circumferential direction of the second balancing member 5132 between different subspaces, which helps to more accurately control the flow path of the liquid and allows the liquid to more effectively adjust its distribution to compensate for vibration according to the vibration of the output shaft 511.

[0152] In some embodiments, combined with Figure 8 and Figure 9 , Figure 9 for Figure 8 The enlarged view at point B shows that the connecting hole 51322 includes a first connecting hole 51322a, which is located on the side of the pusher 51321 near the inner diameter of the balancer.

[0153] In some embodiments, the connecting hole 51322 further includes a second connecting hole 51322b, which is disposed on the side of the pusher 51321 near the outer diameter of the balancer.

[0154] When the output shaft 511 rotates at a lower speed, the centrifugal force on the liquid medium is small, and the liquid medium adjusts its distribution within the accommodating space 51322a from the first connecting hole 51322a. When the output shaft 511 rotates at a high speed, the centrifugal force on the liquid medium is larger, and the liquid medium adjusts its distribution within the accommodating space 51322a from the second connecting hole 51322b. The different positions of the first connecting hole 51322a and the second connecting hole 51322b cause the liquid to form a specific flow direction within the accommodating space 5132a (i.e., from the inner diameter side of the balancing member to the outer diameter side of the balancing member). When the output shaft 511 rotates from a low speed to a high speed, due to the centrifugal force, the liquid tends to flow from the inner diameter side (the side where the first connecting hole 51322a is located) to the outer diameter side (the side where the second connecting hole 51322b is located). This directional flow helps to more accurately adjust the distribution of the liquid within the accommodating space 5132a to adapt to the eccentric vibration of the output shaft 511, thereby effectively compensating for the vibration. Compared to a single connecting hole 51322 or a design without a specific connecting hole 51322, this setting of connecting holes 51322 with different positions can more accurately control the flow path of the liquid, and improve the response speed and compensation effect of the balancing component 513 to vibration.

[0155] In some embodiments, combined with Figure 9 The projected area of ​​the first connecting hole 51322a along the radial direction of the output shaft 511 is larger than the projected area of ​​the second connecting hole 51322b along the radial direction of the output shaft 511. When the output shaft 511 rotates at low speed, the flow velocity of the liquid medium through the first connecting hole 51322a is also relatively slow. When the output shaft 511 rotates at high speed, the flow velocity of the liquid medium through the second connecting hole 51322b is relatively fast. Therefore, the area of ​​the first connecting hole 51322a is larger than the area of ​​the second connecting hole 51322b, thereby ensuring that the flow rate of the liquid medium through the first connecting hole 51322a and the second connecting hole 51322b is not significantly different. This ensures that the liquid medium can flow through the connecting hole 51322 at a similar flow rate in each subspace, regardless of whether the output shaft 511 rotates at low or high speed, thus guaranteeing the response speed and compensation effect of the balancing component 513 to vibration.

[0156] In some embodiments, combined with Figure 9 The first connecting hole 51322a has a first preset length along the axial direction of the output shaft 511, and the first connecting hole 51322a has a first preset width along the radial direction of the output shaft 511.

[0157] In some embodiments, the second connecting hole 51322b has a second preset length along the axial direction of the output shaft 511, and the second connecting hole 51322b has a second preset width along the radial direction of the output shaft 511.

[0158] 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 connecting hole 51322a and the second connecting hole 51322b are provided on the pusher 51321 along the radial direction of the second balancer 5132, the space in the radial direction is limited, while the space in the axial direction of the second balancer 5132 is relatively sufficient. Under the premise that the first preset width and the second preset width are the same in the radial direction, the first preset length is greater than the second preset length, so that the area of ​​the first connecting hole 51322a is greater than the area of ​​the second connecting hole 51322b. This ensures that regardless of whether the output shaft 511 rotates at low or high speed, the liquid medium can flow through the connecting hole 51322 in each subspace at a similar flow rate, thus ensuring the balancing assembly 513's response speed and compensation effect to vibration.

[0159] In some embodiments, combined with Figure 8 and Figure 9 The connecting hole 51322 also includes a third connecting hole 51322c, which is disposed between the first connecting hole 51322a and the second connecting hole 51322b, and is connected to both the first connecting hole 51322a and the second connecting hole 51322b. This allows the liquid medium to flow from the first connecting hole 51322a to the second connecting hole 51322b during the transition from low-speed to high-speed rotation of the output shaft 511. The liquid medium can also flow between the sub-spaces through the third connecting hole 51322c without obstructing its passage between the first and second connecting holes 51322a and 51322b, ensuring that the liquid medium smoothly adjusts its distribution within the accommodating space 5132a.

[0160] In some embodiments, combined with Figure 10 and Figure 18 , Figure 18 for Figure 10 A partial enlarged view at point C shows that the second balancing member 5132 includes an inner ring wall 51323, which is arranged around the output shaft 511.

[0161] In some embodiments, the second balancing member 5132 further includes an inner ring wall 51323, an outer ring wall 51324 is disposed around the inner ring wall 51323, and an accommodating space 5132a is formed between the outer ring wall 51324 and the inner ring wall 51323.

[0162] In some embodiments, the pusher 51321 is connected to the outer ring wall 51324, and the pusher 51321 is spaced apart from the inner ring wall 51323. When the balancing medium is solid particles, multiple solid particles can flow between multiple subspaces through the gap between the pusher 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, thus more fully compensating for the vibration generated by the output shaft 511.

[0163] In some embodiments, combined with Figure 11 Multiple second balancing elements 5132 are provided, each with a ring-shaped structure. These elements are sequentially arranged radially along the output shaft 511, with the innermost ring directly connected to the output shaft 511. Thus, when only the second balancing elements 5132 are provided on the output shaft 511, the limited space within the housing 1 is effectively utilized while maintaining the ring-shaped structure of the second balancing elements 5132. This allows the outermost ring of the second balancing element to be fixed to the output shaft 511, and each second balancing element 5132 can compensate for vibration. When the output shaft 511 rotates at high speed, the multiple second balancing elements 5132 work together to better suppress the large vibrations generated during high-speed rotation, improving the overall stability of the garment processing device 100.

[0164] Moreover, if one of the balancing components fails (such as leakage of internal balancing medium or structural damage), the other balancing components can still continue to compensate for vibration, reducing the risk of serious vibration problems in the entire garment processing device 100 due to the failure of a single balancing component. This improves the reliability and stability of the device, extends its service life, and makes maintenance and repair more convenient.

[0165] In some embodiments, combined with Figure 11The second balancing component 5132 also includes multiple partition rings 51325, all disposed within the accommodating space 5132a. The centers of the partition rings 51325 are all located on the axis of the output shaft 511. The partition rings 51325 are arranged radially along the output shaft 511, with adjacent partition rings spaced apart, dividing the accommodating space 5132a into multiple annular spaces, each filled with a balancing medium. This design makes the second balancing component 5132 a single, integrated structure, resulting in a simpler and more compact design. It reduces the complexity of the installation process, lowers the probability of errors, significantly improves construction efficiency, and reduces the number of parts. This not only simplifies the installation process but also reduces the number of connection points between components, thereby reducing the risk of failure due to loose or damaged connections. The flow range of the balancing medium within each annular space is restricted, allowing the balancing medium to move orderly within its respective annular space to compensate for vibration and enhance the stability of the entire balancing assembly 513.

[0166] It is understandable that, taking the second balancing component 5132, which includes three annular spaces, as an example, or the three second balancing components 5132 working together (three-cavity balancing component), the vibration compensation effect on the output shaft is different compared to the second balancing component 5132, which only has one annular space (single-cavity balancing component), and also differs to some extent from the vibration compensation effect on the output shaft of the first balancing component 5131. The following simulation test is conducted on the maximum amplitude of vibration generated by the second motor 51 and pulley 22 under these three conditions.

[0167] In some embodiments, the garment processing device 100 is a 110L platform, the motor is a fixed-frequency AC motor, the base and inner cross-section are constrained, and a certain force of 200N is applied to the motor shaft to characterize the comprehensive eccentric force, including eccentricity factors. When the output shaft 511 is in a high-speed rotating state, the second balancer 5132 is 180 degrees out of phase with the output shaft 511. Considering the second balancer 5132, which has only one annular space filled with salt water of the same volume ratio, the offset of its center of mass is set to 0.5mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, and 4.0mm, respectively, to obtain the maximum amplitude of vibration generated by the second motor 51 and pulley 22. Simultaneously, for comparative analysis, the offset of the balancer's center of mass is set to 4.0mm, and both the single-cavity and three-cavity balancers are filled with salt water. The maximum amplitude of vibration generated by the second motor 51 and pulley 22 is simulated, and the working conditions of the three different balancers are analyzed. Based on the two simulation experiments above, Table 2 is derived.

[0168]

[0169] Table 2

[0170] Table 2 can be used to plot the trend of the maximum amplitude and the offset of the single-cavity balancing component (e.g., Figure 19 As shown), and when the offset of the balancing component is 4mm, the trend of the maximum amplitude corresponding to the type of balancing component (as shown). Figure 20 (As shown). Referring to Table 2, Figure 19 and Figure 20 Considering only the salt water shift and accumulation effect within the second balancing element 5132, the balancing force generated by the second balancing element 5132 can reduce the maximum amplitude of the second motor 51 and pulley 22 as the output shaft 511 rotates at high speed. Figure 19 It can be seen that as the offset of the center of mass of the same single-cavity balancing component increases, the overall maximum amplitude of the second motor 51 and the maximum amplitude of the pulley 22 gradually decrease. For the same balancing component, the center of mass of the balancing component is 180 degrees out of phase with the output shaft 511. The greater the offset of its center of mass, the smaller the amplitude of the second motor 51 and the pulley 22, resulting in better vibration compensation and a lower probability of the transmission belt 21 displacing relative to the pulley 22 due to vibration or even falling off. Figure 20 It can be seen that for the first balancing component 5131, the single-cavity balancing component (the second balancing component 5132 containing salt water), and the three-cavity balancing component (the second balancing component 5132 containing salt water) with the same outer diameter, and with a center-of-gravity offset of 4mm, the overall maximum amplitude of the second motor 51 equipped with the first balancing component 5131 is greater than that of the second motor 51 equipped with the single-cavity balancing component, and the overall maximum amplitude of the second motor 51 equipped with the single-cavity balancing component is greater than that of the second motor 51 equipped with the three-cavity balancing component. Correspondingly, the maximum amplitude of the pulley 22 on the output shaft 511 equipped with the first balancing component 5131 is greater than that of the pulley 22 on the output shaft 511 equipped with the single-cavity balancing component, and the maximum amplitude of the pulley 22 on the output shaft 511 equipped with the single-cavity balancing component is greater than that of the pulley 22 on the output shaft 511 equipped with the three-cavity balancing component. Therefore, under a certain offset, the vibration compensation effect of the first balancing component 5131, the single-cavity balancing component and the three-cavity balancing component increases in sequence. The three-cavity balancing component has the best vibration compensation effect. The transmission belt 21 has the least possibility of relative displacement or even falling off on the pulley 22 due to vibration, which more effectively ensures the stability of the operation of the clothing processing device 100.

[0171] In some embodiments, combined with Figure 12 , Figure 12This is a schematic diagram of the connection between the first balancing component 5131 and the second balancing component 5132 disclosed in this application embodiment. The first balancing component 5131 is connected to the output shaft 511, and the second balancing component 5132 is connected to one side of the first balancing component 5131 along the axial direction. Since the second balancing component 5132 is a hollow structure, it is inconvenient to directly fix it to the output shaft 511. Therefore, the second balancing component 5132 is connected to the first balancing component 5131, forming a more stable structure. During the operation of the garment handling 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. The two balancing components work simultaneously to compensate for vibration, making the vibration compensation effect better and reducing the vibration of the pulley 22 to a greater extent. This effectively reduces the possibility of the transmission belt 21 causing relative displacement or even detachment on the pulley 22 due to vibration.

[0172] In some embodiments, the second balancing member 5132 is connected to the first balancing member 5131 via a welding process. Welding is a common metal surface repair and protection technology. It involves melting metal powder or wire and applying it to the damaged area to repair and enhance the performance of the metal structure. It has wide applications in industrial manufacturing and repair, and requires processes such as surface cleaning and pretreatment, selection of appropriate welding equipment and parameters, welding operation, polishing, and coating. Compared to traditional welding methods, welding does not require a large amount of heat input, effectively reducing thermal deformation and residual stress, minimizing the impact on the substrate material, providing good adhesion strength, and offering excellent wear resistance, corrosion resistance, and high-temperature resistance.

[0173] The second balancing component 5132 and the first balancing component 5131 are connected using a welding process, achieving a relatively secure connection between them. During the operation of the garment handling device 100, especially when the output shaft 511 rotates, vibrations and centrifugal forces are generated. The connection formed by the welding process can withstand these forces, preventing loosening or separation between the second balancing component 5132 and the first balancing component 5131, thereby ensuring the overall structural integrity of the balancing assembly 513. This ensures that the balancing assembly 513 can effectively compensate for the vibration of the output shaft 511 throughout the entire service life of the garment handling device 100.

[0174] In some embodiments, combined with Figure 13 , Figure 13This is a schematic diagram of the connecting bracket 5133 disclosed in an embodiment of this application. The balancing assembly 513 also includes a connecting bracket 5133, which is connected to the output shaft 511. The second balancing member 5132 is connected to the connecting bracket 5133. This connection method allows the second balancing member 5132 to maintain a stable position when the output shaft 511 rotates. The connecting bracket 5133 provides a reliable connection foundation for the second balancing member 5132, preventing displacement of the second balancing member 5132 during operation and ensuring the stability of the entire balancing assembly 513 structure. The presence of the connecting bracket 5133 can effectively transmit torque, enabling the second balancing member 5132 to work in coordination with the rotation of the output shaft 511. Simultaneously, when the output shaft 511 vibrates, the supporting and connecting effect of the connecting bracket 5133 reduces the swaying of the second balancing member 5132 due to vibration, thereby improving the stability of the entire balancing assembly 513.

[0175] In some embodiments, combined with Figure 13 The connecting bracket 5133 is an annular bracket, which is sleeved on the output shaft 511. The second balancing component 5132 is an annular structure, which is sleeved on the outer periphery of the annular bracket. The annular bracket sleeved on the output shaft 511 provides a stable support structure for the second balancing component 5132. This design ensures that the annular structure of the annular bracket and the second balancing component 5132 can better cooperate, making the connection between the second balancing component 5132 and the output shaft 511 more stable when the output shaft 511 rotates, thereby ensuring the stability of the balancing assembly 513.

[0176] In some embodiments, combined with Figure 13 The connecting bracket 5133 includes a sleeve 51331, which is sleeved on the output shaft 511 and can transmit torque between itself and the output shaft 511.

[0177] In some embodiments, the connecting bracket 5133 further includes a support ring 51332, which is disposed around the outer periphery of the sleeve 51331. The support ring 51332 is coaxially disposed with the sleeve 51331, and the second balance member 5132 is sleeved on the outer peripheral wall of the support ring 51332.

[0178] In some embodiments, the connecting bracket 5133 further includes a support rib 51333, which connects the sleeve 51331 and the support ring 51332. The sleeve 51331 is fitted onto the output shaft 511 and can transmit torque, ensuring reliable power transmission between the connecting bracket 5133 and the output shaft 511, enhancing the stability of the connecting bracket 5133 on the output shaft 511, preventing the connecting bracket 5133 from sliding or shifting relative to the output shaft 511, thereby improving the structural stability of the entire balancing assembly 513. The support ring 51332 is arranged around the outer periphery of the sleeve 51331 and is coaxial with the sleeve 51331. This structure further strengthens the integrity of the connecting bracket 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 bracket 5133 from deforming or being damaged. The support ring 51332 provides a matching outer peripheral wall for the second balancer 5132, enabling the second balancer 5132 to be stably installed on the connecting bracket 5133, which helps to improve the compensation effect of the balancer assembly 513 on the vibration of the output shaft 511.

[0179] In some embodiments, combined with Figure 13 Multiple support ribs 51333 are provided, each extending radially along the output shaft 511, and distributed circumferentially along the output shaft 511. The line connecting the two ends of each support rib along the axial direction of the output shaft 511 passes through its axis. This distribution ensures that the force borne by the connecting bracket 5133 is evenly distributed circumferentially. During operation of the garment handling device 100, the connecting bracket 5133 needs to withstand forces from multiple sources, such as the gravity of the second balancing member 5132, centrifugal force, and impact forces generated by the vibration of the output shaft 511. The support ribs 51333 ensure that no local area bears excessive force, thus avoiding the risk of damage to the connecting bracket 5133 due to localized stress concentration. This helps improve the overall structural strength and stability of the connecting bracket 5133 and extends its service life.

[0180] In some embodiments, the connecting bracket 5133 is made of a rigid material. The rigid material of the connecting bracket 5133 provides better structural stability, ensuring that the connecting bracket 5133 can withstand the corresponding forces and vibrations 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 balance assembly 513.

[0181] In some embodiments, the connecting bracket 5133 is a plastic component. Plastic materials are generally lightweight, which helps reduce the overall weight of the garment handling device 100. Plastic materials also have good corrosion resistance, resisting the erosion of chemicals and moisture that may be encountered in daily use, thereby extending 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 in the design of the connecting bracket 5133. In addition, plastic materials are generally low-cost; using a plastic connecting bracket 5133 can reduce production costs, thereby lowering product prices and improving market competitiveness.

[0182] In some embodiments, the first balancer 5131 is made of metal, and the second balancer 5132 is made of rubber. The metal first balancer 5131 typically has high density and rigidity, providing a stable mass distribution that helps compensate for vibrations when the output shaft 511 rotates. The rubber second balancer 5132, on the other hand, has good elasticity and damping characteristics, absorbing and dissipating vibration energy, further enhancing the balancing effect. The combination of the two allows them to leverage their respective advantages across different vibration frequency ranges, improving overall balancing performance. Furthermore, considering material costs and manufacturing feasibility while meeting performance requirements, this combination may be more economical than a single-material balancer 513, and is also easier to manufacture.

[0183] In some embodiments, combined with Figure 7 and Figure 14 , Figure 7 This is a schematic diagram of another structure of the second balancer 5132 disclosed in the embodiments of this application (including the output shaft 511). Figure 14 for Figure 7 The exploded view shows that the second motor 51 also includes a limiting part 5111, which is disposed on the output shaft 511 and is used to limit the movement of the first balancer 5131 along the circumferential direction of the output shaft 511.

[0184] In some embodiments, the second motor 51 further includes a mating part 5112, which is disposed on the inner wall of the first balancing member 5131. The mating part 5112 engages with the limiting part 5111 to enable the output shaft 511 to drive the first balancing member 5131 to rotate. This allows the first balancing member 5131 to compensate for the vibration generated by the output shaft 511 during its rotation, effectively reducing noise caused by vibration and minimizing the possibility of the transmission belt 21 shifting relative to the pulley 22 or even falling off due to vibration. This extends the service life of the equipment and reduces maintenance and replacement costs. Thus, the output shaft can drive the first balancing member to rotate without adding other parts, simplifying the assembly process.

[0185] In some embodiments, combined with Figure 7 and Figure 14 The limiting part 5111 is a flat portion formed on the outer peripheral surface of the output shaft 511, and the mating part 5112 is a flat portion formed on the inner wall of the first balancing member 5131. The flat portion fits against the flat portion to prevent the first balancing member 5131 from rotating relative to the output shaft 511. Here, the flat portion typically refers to a flat portion on a shaft-like workpiece. This flat portion differs from the circular cross-section of the shaft; it is flat. Flat portions are common in machining, especially on shaft-like parts that need to be connected or transmitted with other components. For example, on some drive shafts, the flat portion can be used for keyed connections with other components or as a positioning surface. This structure ensures the effective transmission of power from the output shaft 511 to the first balancing member 5131, avoiding energy loss caused by relative rotation, and making the entire drive assembly 5 more compact and reliable. During the operation of the garment handling device 100, it ensures that the balancing assembly 513 works in coordination with the output shaft 511 to accurately compensate for the vibrations generated by the output shaft 511.

[0186] In some embodiments, combined with Figure 4 and Figure 5 The second motor 51 also includes a motor housing 512, with an output shaft 511 passing through it. The output shaft 511 includes a first end 511a and a second end 511b, which extend from opposite sidewalls of the motor housing 512. The first end 511a is connected to the roller 2 via a transmission, and a balancing component 513 is disposed at the second end 511b. The two ends of the output shaft 511 extend from the motor housing 512, and the addition of the balancing component 513 at the second end 511b makes the forces on both ends of the output shaft 511 more balanced during rotation, thus balancing the center of gravity of the output shaft 511, further reducing the vibration of the output shaft 511, and improving the stability of the drive assembly 5.

[0187] In some embodiments, combined with Figure 7 and Figure 14 The second motor 51 also includes an axial positioning structure 514, which is disposed 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. The axial positioning structure 514 can ensure that the balancing assembly 513 is fixed in position on the output shaft 511 and prevent it from being displaced in the axial direction. Especially when the output shaft 511 rotates at high speed, it 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 drive assembly 5.

[0188] In some embodiments, combined with Figure 7 and Figure 14 The axial positioning structure 514 includes a shoulder 5141, which is disposed on the output shaft 511.

[0189] In some embodiments, the axial positioning structure 514 further includes a stop 5142, detachably mounted on the output shaft 511, and a balancing assembly 513 disposed between the shoulder 5141 and the stop 5142. The shoulder 5141 is typically where the shaft diameter changes, forming a step-like shape. It can be a portion whose diameter suddenly increases or decreases during shaft machining, created by processes such as turning. In this embodiment, the output shaft 511 has a portion with a suddenly decreasing diameter during machining to accommodate the balancing assembly 513, so that one side of the balancing assembly 513 abuts against the side with the larger diameter in the axial direction. The other side of the balancing assembly 513 abuts against the stop 5142. The shoulder 5141 and the stop 5142 cooperate to provide precise axial positioning for the balancing assembly 513. This allows the balancing assembly 513 to be accurately mounted at a predetermined position on the output shaft 511, ensuring its proper function of compensating for vibrations when the output shaft 511 rotates. Furthermore, the balancing assembly 513 is more easily disassembled by flexibly removing the stop 5142.

[0190] In some embodiments, the stop 5142 can be a nut, threadedly connected to the end of the output shaft 511. The nut is a common and standardized fastener, easy to install and remove, facilitating periodic maintenance or replacement of damaged components (such as the stop 5142, the balancing assembly 513, etc.). The nut has good tightening performance and, when engaged with the shaft shoulder 5141, provides reliable axial positioning, preventing axial displacement of the balancing assembly 513 during operation.

[0191] In some embodiments, combined with Figure 4 The balancing assembly 513 includes a first balancing element 5131, which is disposed on the output shaft 511.

[0192] In some embodiments, the balancing assembly 513 further includes an absorber (not shown in the figure), which is disposed on the output shaft 511. The absorber is made of sound-absorbing material and / or water-absorbing material; that is, the absorber can be a sound-absorbing material or a water-absorbing material, or a material that can absorb both sound and water. Adding a first balancing assembly 5131 to the output shaft 511 of the motor can effectively reduce vibration. When the absorber is made of sound-absorbing material, it can absorb the noise generated by the second motor 51, thereby further reducing the overall noise of the machine. When the absorber is made of water-absorbing material, it can absorb the liquid water condensed from the water vapor around the second motor 51, and can throw the adsorbed water out when the output shaft 511 rotates at high speed, improving the collection efficiency of condensate.

[0193] In some embodiments, the absorbent element is made of a porous material. Porous materials have excellent sound absorption properties, effectively absorbing noise generated during device operation and providing a quieter operating environment. This is particularly important for the clothing handling device 100 in a home environment, as users typically prefer to use these devices without being disturbed by noise. Porous materials can also absorb moisture, maintaining a dry environment inside the device, thereby improving its performance and lifespan. By reducing noise and absorbing moisture, the porous absorbent element effectively improves the stability and safety of the drive assembly 5.

[0194] In some embodiments, the absorber is made of sponge, polyurethane foam, or foam rubber. When the absorber is sponge, sponge is a porous material that effectively absorbs sound waves and reduces noise transmission. Sponge can also absorb a large amount of moisture, used to absorb moisture around the second motor 51 and maintain a dry working environment. Additionally, the elasticity and porosity of sponge also provide a certain degree of vibration damping; when the output shaft 511 vibrates and generates a certain impact, the sponge can be compressed to reduce the impact force. When the absorber is polyurethane foam, polyurethane foam has excellent sound absorption properties and can effectively absorb and isolate noise. The elasticity and plasticity of polyurethane foam make it a good shock-absorbing and cushioning material, protecting the first balancing member 5131 from impacts and vibrations. When the absorber is foam rubber, the porous structure of foam rubber provides good sound absorption and insulation effects. Foam rubber also has elasticity and plasticity, achieving a good vibration damping effect.

[0195] In some embodiments, the absorber is an annular structure. The annular structure allows the absorber to be evenly distributed along the output shaft 511, ensuring uniform sound absorption and / or water absorption effects around the circumference of the output shaft 511. The annular structure also ensures the absorber remains balanced during rotation, helping to reduce displacement and vibration caused by unbalanced forces, thereby reducing noise and improving equipment stability. The annular structure can also uniformly increase the contact area between the absorber and air or moisture, which helps improve the efficiency of noise and moisture absorption, thus enhancing the overall care effect.

[0196] In some embodiments, combined with Figure 4The absorber and the first balancer 5131 are arranged axially, and the absorber is connected to the first balancer 5131. Since the absorber is flexible and cannot be directly fixed to the output shaft 511, fixing the absorber to the first balancer 5131 results in a larger contact area and a more stable structure. During the operation of the garment handling device 100, especially during high-speed rotation or load changes, this connection method enhances the overall stability of the balancer assembly 513. The axial contact between the absorber and the first balancer 5131 improves the absorber's noise absorption effect, ensuring that it can absorb noise generated by the vibration of the output shaft 511, and also effectively absorb noise generated by the first balancer 5131 during vibration compensation. Furthermore, the first balancer 5131 provides a more stable mounting platform for the absorber, preventing it from easily detaching from the output shaft 511 due to centrifugal force when the output shaft 511 rotates at high speed.

[0197] In some embodiments, when the absorbent is made of a water-absorbing material, the output shaft 511 rotates at high speed, and the water absorbed inside the absorbent is flung out. This water can flow along the inner wall of the base of the clothing treatment device 100 to the water collection tank (not shown in the figure), and then be pumped into the end water box (not shown in the figure) by a water pump. During the operation of the clothing treatment device 100, the absorbent absorbs a large amount of water. When the output shaft 511 rotates at high speed, the water inside the absorbent is flung out due to centrifugal force. The water collection tank prevents this water from flowing or accumulating randomly inside the device. The water collection tank can collect the water flung out by the absorbent in a timely manner, preventing water from accumulating on other components inside the device, thereby reducing problems such as rust and corrosion caused by water.

[0198] For clothing processing devices 100 containing electrical components, such as the compressor 6 and fan motor in the heating system 4, a dry environment is crucial for ensuring their normal operation and electrical safety. The presence of moisture can cause electrical faults such as short circuits. The collection tank maintains a dry environment inside the device by collecting moisture, which helps ensure the safe operation of electrical components. Furthermore, if the absorbent absorbs too much moisture and cannot drain it promptly, its absorption capacity will decrease. The collection tank collects the water that is shaken out, allowing the absorbent to maintain good absorption performance, ensuring effective absorption of both moisture and noise. Prolonged dampness can affect the material properties and structural integrity of the absorbent. By draining moisture promptly through the collection tank, the absorbent can operate in a relatively dry state, reducing material aging and deformation caused by prolonged dampness, thus extending the lifespan of the absorbent.

[0199] In some embodiments, combined with Figure 15 , Figure 15This is a schematic diagram showing the positions of the compressor 6, the second fan 5134, and the motor disclosed in this application embodiment. The clothes handling device 100 also includes a compressor 6, which is located on one side of the second motor 51. The compressor 6 compresses the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas. The high-temperature, high-pressure refrigerant gas enters the condenser, where it releases heat. This heat is used to heat the air. The heated drying gas is then sent into the drum 2 of the clothes handling device 100, where it comes into contact with the wet clothes, causing the moisture in the clothes to evaporate into water vapor. The air containing water vapor is guided to the evaporator, where the refrigerant absorbs the heat from the air, causing the water vapor to condense into liquid water, thereby achieving dehumidification. The dehumidified air is then sent back into the compressor 6 to start a new cycle until the clothes are dried.

[0200] In some embodiments, the fan includes a first fan, which is correspondingly disposed with the air duct assembly 3. A first motor drives the first fan to rotate. The first fan is used to send drying gas into the air duct assembly 3 and to allow the drying gas to enter the drying chamber through the air duct assembly 3.

[0201] In some embodiments, the garment handling device 100 further includes a second fan 5134, which is disposed on the output shaft 511 and opposite to the compressor 6. When the output shaft 511 of the second motor 51 rotates, it can drive the second fan 5134 to rotate, so as to deliver cooling air to the compressor 6. During the operation of the compressor 6, the compressor 6 generates a lot of heat. Originally, a cooling fan was provided on the side of the compressor 6 away from the second motor 51 to cool the compressor 6. In this embodiment, the cooling fan is eliminated, and the compressor 6 is moved to the side away from the second motor 51. A fan is added to the shaft end of the output shaft 511 to cool the compressor 6. This not only ensures the cooling of the compressor 6, but also compensates for the vibration of the output shaft 511.

[0202] In some embodiments, combined with Figure 16 , Figure 16 This is a schematic diagram of the structure of the second fan 5134 disclosed in the embodiment of this application. 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 accordingly.

[0203] In some embodiments, the second fan 5134 further includes an outer ring fan 51342, which is an axial 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 the output shaft 511 can drive the second fan 5134 to deliver cooling air to the compressor 6 when rotating forward and in reverse.

[0204] When the output shaft 511 is in either forward or reverse rotation, the inner ring fan 51341 supplies cooling air to the compressor 6, and the outer ring fan 51342 supplies cooling air to the second motor 51. When the output shaft 511 is in either forward or reverse rotation, the outer ring fan 51342 supplies cooling air to the compressor 6, and the inner ring fan 51341 supplies cooling air to the second motor 51. Therefore, regardless of whether the output shaft 511 is in forward or reverse rotation, either the inner ring fan 51341 or the outer ring fan 51342 can supply cooling air to the compressor 6, and the other can supply cooling air to the second motor 51.

[0205] The axial fan operates by generating airflow through the rotation of an impeller, typically composed of multiple blades. When the second motor 51 starts, the output shaft 511 drives the impeller to rotate, causing airflow. The blades draw air in from one side of the impeller and then discharge it to the other side through the hollow section at the center of the shaft. As air is drawn in, it passes through the blades and is compressed, then pushed to the blade tips, forming a high-speed airflow. This high-speed airflow is ejected from the blade tips and propels along the impeller's axis. During the operation of the garment handling device 100, the output shaft 511 may rotate forward or backward due to different operating modes or malfunctions. Regardless of the direction of rotation, the output shaft 511 ensures a continuous supply of cooling air to the compressor 6, guaranteeing its operation within a suitable temperature range, improving its reliability and lifespan, and making the entire device operate more stably. Furthermore, while ensuring a constant supply of cooling air to the compressor 6, the second motor 51 is also continuously supplied with cooling air, further ensuring its normal operation.

[0206] In some embodiments, combined with Figure 16 The second fan 5134 also includes a first connecting ring 51342a, which is disposed around the outer periphery of the inner ring fan 51341, and the inner surface of the first connecting ring 51342a is connected to the inner ring fan 51341, while the outer ring fan 51342 is connected to the outer surface of the first connecting ring 51342a.

[0207] The first connecting ring 51342a enhances the connection stability between the inner ring fan 51341 and the outer ring fan 51342. During fan rotation, especially at high speeds, this stable connection structure reduces blade wobble and deformation, thereby improving the overall stability and reliability of the fan.

[0208] In some embodiments, combined with Figure 16The second fan 5134 also includes a second connecting ring 51342b, which is disposed around the outer periphery of the outer fan 51342 and is connected to the outer fan 51342.

[0209] The second connecting ring 51342b further enhances the structural strength of the outer ring fan 51342. During fan rotation, especially when facing different operating conditions and load changes, the second connecting ring 51342b can provide additional support, reducing the risk of fan blade deformation and damage.

[0210] In some embodiments, combined with Figure 16 The inner ring fan 51341 includes a plurality of first blades (not shown in the figure), and the edge of the first blade for connecting with the first connecting ring 51342a is the first edge 51341a.

[0211] In some embodiments, the outer ring fan 51342 includes a plurality of second blades (not shown in the figure), the edge of which the second blades are connected to the second connecting ring 51342b is a second edge 51342c. Both the first edge 51341a and the second edge 51342c are helical, and the first edge 51341a and the second edge 51342c have opposite directions of rotation.

[0212] Thus, with the first edge 51341a and the second edge 51342c rotating in opposite directions, the inner ring fan 51341 and the outer ring fan 51342 can deliver cooling air to the compressor 6 and the motor body when the output shaft 511 rotates. This increases the service life of the compressor and the second motor and improves the overall efficiency of the device.

[0213] In some embodiments, combined with Figure 4 , Figure 15 and Figure 16 The second motor 51 includes a motor housing 512. The first end 511a of the output shaft 511 extends from the motor housing 512 towards the side wall of the compressor 6. The first end 511a of the output shaft 511 is connected to the roller 2 via a drive mechanism. The second fan 5134 is located at the first end 511a of the output shaft 511. This layout enhances the integration between components. Because the second fan 5134 is located close to the compressor 6 and shares the same shaft end with the pulley 22, power can be easily transmitted from the output shaft 511 to the roller 2 while simultaneously driving the second fan 5134 to rotate, thereby providing cooling air to the compressor 6 and improving the overall efficiency of the device. Within a limited space, this rational layout reduces the overall volume of the device, saving space resources.
