Description

TECHNICAL FIELD

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

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

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

[0004] The present application discloses a clothes treatment device that can independently control the fan and the rotation of the drum while ensuring the cooling of the compressor and compensating for the vibration of the output shaft.

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

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

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

[0008] An air duct assembly in communication with the drying cavity for guiding drying gas into the drying cavity;

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

[0010] A compressor arranged in the base;

[0011] A first fan is arranged corresponding to the air duct assembly, and is used to send the drying gas into the air duct assembly and make the drying gas pass through the air duct assembly into the drying cavity.

[0012] A driving assembly is in driving connection with the drum and the first fan respectively, and is configured to drive the drum and the first fan to rotate, and the driving assembly comprises:

[0013] A first motor is connected to the first fan and is used to drive the first fan to rotate;

[0014] A second motor is in driving connection with the drum through a transmission belt and is used to drive the drum to rotate, and the second motor comprises:

[0015] An output shaft is in driving connection with the drum to drive the drum to rotate;

[0016] A second fan is arranged on the output shaft and opposite to the compressor, and the output shaft can drive the second fan to rotate when rotating to send cooling air to the compressor.

[0017] In this way, the second fan added at the shaft end of the output shaft cools the compressor, which not only ensures the cooling of the compressor, but also compensates the vibration of the output shaft, so as to effectively reduce the noise caused by the vibration.

[0018] As an optional implementation, the second fan comprises:

[0019] An inner ring fan, which is an axial fan, is connected to the output shaft;

[0020] An outer ring fan, which is an axial fan, is connected to the outer periphery of the inner ring fan;

[0021] The air outlet directions of the inner ring fan and the outer ring fan are opposite, so that the output shaft can drive the second fan to send cooling air to the compressor when rotating in the forward direction and the reverse direction.

[0022] In this way, the cooling air supply to the compressor can be ensured regardless of the rotating direction of the output shaft, so as to ensure that the compressor can continuously work in a suitable temperature range, improve the reliability and service life of the compressor, and make the entire device operate more stably.

[0023] As an optional implementation, the second fan further comprises:

[0024] A first connecting ring is arranged around the outer periphery of the inner ring fan, and the inner surface of the first connecting ring is connected to the inner ring fan.

[0025] The outer ring fan is connected to the outer surface of the first connecting ring.

[0026] In this way, the connection stability between the inner ring fan and the outer ring fan is enhanced. During the rotation of the fan, especially at high speed, this stable connection structure can reduce the shaking and deformation of the fan blades, thereby improving the overall stability and reliability of the fan.

[0027] As an optional implementation, the second fan further comprises:

[0028] A second connecting ring, which surrounds the outer periphery of the outer ring fan, and the inner surface of the second connecting ring is connected to the outer ring fan.

[0029] In this way, the arrangement of the second connecting ring further enhances the structural strength of the outer ring fan. During the rotation of the fan, especially when facing different working conditions and load changes, the second connecting ring can provide additional support force to reduce the risk of deformation and damage of the fan blades.

[0030] As an optional implementation, the inner ring fan comprises:

[0031] A plurality of first blades, the edge of which for connecting with the first connecting ring is a first edge;

[0032] The outer ring fan comprises:

[0033] A plurality of second blades, the edge of which for connecting with the second connecting ring is a second edge, the first edge and the second edge are both spiral lines, and the rotation directions of the first edge and the second edge are opposite.

[0034] In this way, the rotation directions of the first edge and the second edge are opposite, which can realize that the air outlet directions of the inner ring fan and the outer ring fan are opposite when the output shaft rotates, and the second fan can deliver cooling air to the compressor and the motor body when the output shaft rotates in any direction, thereby increasing the service life of the compressor and the second motor.

[0035] As an optional implementation, the second motor further comprises:

[0036] A motor shell;

[0037] The first end of the output shaft protrudes from the motor shell towards the side wall of the compressor;

[0038] The first end of the output shaft is in transmission connection with the drum, and the second fan is arranged at the first end of the output shaft.

[0039] Therefore, the layout enhances the integration between components, and since the second fan is arranged close to the compressor, the power is transmitted from the output shaft to the drum while conveniently driving the second fan to rotate, thereby providing cooling air for the compressor and improving the cooperation efficiency of the whole device. In the limited space, the reasonable layout reduces the overall volume of the device and saves space resources.

[0040] As an optional implementation, the second motor further comprises:

[0041] A limiting portion is arranged on the output shaft;

[0042] A matching portion is arranged on the inner hole wall of the second fan, and the matching portion is matched with the limiting portion to enable the output shaft to drive the second fan to rotate.

[0043] Therefore, the output shaft can drive the second fan to rotate without adding other parts, thereby simplifying the assembly process.

[0044] As an optional implementation, the limiting portion is a flat portion formed on the outer circumferential surface of the output shaft;

[0045] The matching portion is a flat portion formed on the inner hole wall of the second fan, and the flat portion is matched with the flat portion to prevent the second fan from rotating relative to the output shaft.

[0046] Therefore, the effective transmission of power from the output shaft to the second fan is ensured, the energy loss caused by relative rotation is avoided, the structure of the whole driving assembly is more compact and reliable, and in the operation of the clothes treatment device, the second fan can work cooperatively with the output shaft to cool the compressor and compensate the vibration generated by the output shaft.

[0047] As an optional implementation, the second motor further comprises:

[0048] An axial positioning structure is arranged between the second fan and the output shaft to prevent the second fan from moving axially relative to the output shaft.

[0049] Therefore, the axial positioning structure can ensure the position of the second fan on the output shaft to be fixed, prevent the second fan from moving in the axial direction, especially when the output shaft rotates at a high speed, reduce the instability of the effects of failing to cool the compressor normally and compensating the vibration caused by the movement of the second fan, thereby improving the stability and reliability of the whole driving assembly.

[0050] As an optional implementation, the axial positioning structure comprises:

[0051] A shaft shoulder is arranged on the output shaft;

[0052] A stop component is detachably mounted on the output shaft;

[0053] The second fan is disposed between the shoulder and the stop.

[0054] In this way, the shoulder and the stop piece cooperate to provide precise axial positioning for the second fan. This ensures that the second fan can be accurately installed in the predetermined position on the output shaft and can perform its function of cooling the compressor and compensating for vibration when the output shaft rotates. It also makes it easier to disassemble the second fan.

[0055] Compared with the prior art, the beneficial effects of this application are:

[0056] The clothing processing device provided in this application adds a second fan to the end of the output shaft to cool the compressor. This not only ensures the cooling of the compressor, but also compensates for the vibration of the output shaft, effectively reducing the noise caused by vibration. Attached Figure Description

[0087] The laundry treatment device is an important branch of household appliances, and the laundry treatment device includes a clothes dryer and a washer-dryer. The clothes dryer heats and dries clothes by recycling heat energy. A drum containing clothes rotates during the drying process to increase the contact area of the clothes with hot air, making the drying more uniform and improving the drying efficiency. When the motor controls the rotation of the drum in the laundry treatment device, due to the manufacturing tolerance of the drum, the geometric center of the drum deviates from its original rotation center, so that the drum produces circular runout. Therefore, the drum will have periodic fluctuations, which will generate exciting force on the motor, causing the motor to vibrate and produce noise, which brings a bad user experience.

[0088] Based on this, the embodiments of the present application disclose a laundry treatment device. A balancing assembly is arranged at the shaft end of the motor that controls the rotation of the drum, which is used to compensate for the vibration generated by the output shaft of the motor during rotation, thereby reducing noise.

[0089] The technical solutions of the present application will be further described below in conjunction with the embodiments and the drawings.

[0090] Please refer to Figure 1 , Figure 1 The structure schematic diagram of the laundry treatment device 100 disclosed by the embodiments of the present application is shown. The embodiments of the present application disclose a laundry treatment device 100, which can be a clothes dryer or a washer-dryer.

[0091] The laundry treatment device 100 includes a housing 1, which is the external structure of the device, usually made of metal or plastic, used to protect the internal components of the laundry treatment device 100 and provide stable support. Durability, heat dissipation performance, noise control, safety and maintainability are considered when designing the housing 1. The housing 1 is designed around the drum 2 inside to accommodate and protect the drum 2 and other internal structures. The housing 1 includes a base for setting part of the internal structure.

[0092] In some embodiments, please refer to Figure 2 , Figure 2A structure diagram of the inside of the laundry processing device 100 disclosed in the embodiments of the present application. The shell 1 is provided with a drum 2, and the drum 2 forms a drying cavity for loading laundry. The drum 2 loaded with laundry rotates during the drying process to increase the contact area between the laundry and the hot air, making the drying more uniform and improving the drying efficiency. The drum 2 is usually made of stainless steel to ensure strength and corrosion resistance. The drum 2 can be equipped with protrusions that can increase the contact area with wet laundry and promote the conduction of hot air to the laundry, thereby improving the drying efficiency.

[0093] In some embodiments, in combination with Figure 2 , the shell 1 is provided with a feeding port 1a, which is arranged in the axial direction of the drum 2 and corresponds to the drum 2, for feeding laundry into the drum 2.

[0094] In some embodiments, in combination with Figure 3 , Figure 3 A structure diagram of the inside of the laundry processing device 100 (omitting the drum 2) disclosed in the embodiments of the present application. The shell 1 is provided with an air duct assembly 3, which communicates with the drying cavity and is used to guide the drying gas into the drying cavity. The air duct is designed considering aerodynamics to optimize the airflow path, reduce air resistance, and improve the transmission efficiency of the drying gas. The air duct can be equipped with a fan, and the fan can be equipped with a wind guide piece for guiding the airflow to the drum of the laundry processing device, ensuring that the laundry can fully contact the drying gas.

[0095] In some embodiments, in combination with Figure 3 , the shell 1 is provided with a heating system 4 for providing a heat source, which can use electric heating or heat pump system, etc. to exchange heat between the air and the heat source to form drying gas. The efficient heating system 4 can quickly transfer heat to the air duct, reduce energy consumption, and at the same time provide enough heat to ensure that the laundry can be dried in a short time.

[0096] In some embodiments, in combination with Figure 3 , the shell 1 is provided with a fan (not shown in the figure), which is arranged corresponding to the air duct assembly 3. The fan is used to send the drying gas into the air duct assembly 3, and the drying gas enters the drying cavity through the air duct assembly 3.

[0097] Among them, the clothes dryer mainly includes a heat pump type clothes dryer, a condenser type clothes dryer and an exhaust type clothes dryer. Different types of clothes dryers all have the above structure, but the drying principle is different.

[0098] The working principle of a heat pump type clothes dryer is generally based on heat pump technology, which uses heat energy recycling to heat and dry clothes. The working principle of a heat pump type clothes dryer is to achieve low-temperature drying through a heat pump circulation system (heating system 4). The heat pump circulation system is usually composed of a compressor 6, a condenser, a throttle valve and an evaporator, and is filled with appropriate circulating working medium. During operation, the low-temperature and low-pressure working medium absorbs heat from the surrounding environment (such as the interior of the clothes dryer) in the evaporator and evaporates into gas. In this process, the working medium absorbs the moisture in the clothes, and its temperature rises. Subsequently, the high-temperature working gas is sucked into the compressor 6 and compressed, and the temperature and pressure increase, changing into high-temperature and high-pressure gas. This high-temperature working gas (drying gas) then flows into the condenser, where it releases heat, which is transferred to the air inside the clothes dryer through the air duct assembly 3 (the air duct assembly 3 is in communication with the drying chamber for guiding the drying gas into the drying chamber), while the working medium itself condenses into a liquid state. The condensed liquid working medium is depressurized by the throttle valve and enters the evaporator, where it absorbs more heat and re-evaporates into gas, completing the cycle. The fan drives the gas flow in the air duct assembly 3 to achieve circulation. This cycle is repeated until the moisture in the clothes is completely evaporated, achieving the drying effect. The advantage of a heat pump type clothes dryer is that it has a higher energy efficiency, as it can recover heat from the environment for drying, rather than directly consuming electricity to generate heat like traditional resistance heating clothes dryers. In addition, the heat pump type clothes dryer produces lower temperatures during operation, which is gentler on clothes and helps protect the fibers of the clothes, reducing the risk of shrinkage and damage to the clothes.

[0099] The working principle of a condensation type clothes dryer is based on condensation technology, which is used to remove water from wet clothes. The heater (heating system 4) inside the dryer is powered to heat up, producing dry hot air that is blown into the dryer's drum 2 by a fan, passing through the wet clothes and absorbing the moisture in the clothes. The humid hot air then flows through the condenser, where the cooling surface of the condenser causes the water vapor in the air to condense into droplets, which collect in a container inside the condenser or are drained through a connected hose. The dry hot air loses its moisture after passing through the condenser and becomes dry and is reheated again, circulating in the air duct assembly 3 into the drum 2, continuing to dry the clothes. The condensed water is drained outside the dryer through a pre-set method (water tank or drain pipe).

[0100] An exhaust type clothes dryer is a device that removes moisture from clothes by heating air and blowing it into the interior of the drum 2. The dryer is equipped with heating elements (heating system 4), usually electric heating wires, which heat the air drawn in. The heated air is transported to the interior of the dryer's drum 2 through the air duct assembly 3 by a fan, and the hot air passes through the clothes, absorbing the moisture in the clothes and flowing with the hot air to the other end of the dryer. The hot air containing moisture is discharged to the indoor or outdoor environment through the exhaust pipe.

[0101] Washing and drying machines usually integrate washing and drying functions, and they can use different drying technologies to dry clothes. Heat pump type is suitable for families pursuing drying quality due to its low-temperature drying, energy saving, environmental protection and mildness to clothes. The structure of condensing type and exhaust type is relatively simple and low in cost, which is suitable for users with limited budget.

[0102] In some embodiments, in combination Figure 2 The housing 1 is also provided with a driving assembly 5 arranged on the base. The driving assembly 5 is in driving connection with the drum 2 and the fan respectively. The driving assembly 5 can drive the drum 2 and the fan to rotate synchronously or separately. When the drum 2 and the fan are arranged on the same motor, they rotate synchronously. When the drum 2 and the fan are controlled by two motors respectively, they rotate separately. The present embodiment does not limit this.

[0103] In some embodiments, the driving assembly 5 includes a first motor (not shown in the figure) connected to the fan for driving the fan to rotate.

[0104] In some embodiments, the driving assembly 5 further includes a second motor 51 in driving connection with the drum 2 for driving the drum 2 to rotate.

[0105] In some embodiments, in combination Figure 2 and Figure 4 , Figure 4 The second motor 51 (including the pulley 22) disclosed in the embodiments of the present application is a structural schematic view. The second motor 51 includes an output shaft 511 in driving connection with the drum 2 through a transmission belt 21 to drive the drum 2 to rotate. Since the diameter of the drum 2 is much larger than that of the output shaft 511, when the output shaft 511 rotates at high speed, the rotation speed of the drum 2 is reduced through the belt, so that the clothes in the drum 2 rotate at a slower speed, increasing the contact area between the clothes and the hot air, and making the drying more uniform.

[0106] It should be noted that the output shaft 511 usually has two states, namely a low-speed rotation state and a high-speed rotation state. Low speed usually refers to the rotation speed of the motor during the starting stage, and high speed usually refers to the rotation speed of the output shaft 511 when the rotation speed exceeds the low-frequency resonance of the suspension system. The high and low of the two rotation speeds are only relative concepts, and are not a certain speed range. The low-frequency resonance refers to the phenomenon that the vibration frequency of the washing machine matches the natural frequency of the washing machine itself during the operation of the washing machine, so that the vibration amplitude increases significantly.

[0107] In some embodiments, in combination Figure 2 and Figure 4The second motor 51 further comprises a belt pulley 22, which is arranged on the output shaft 511 and is in transmission connection with the drum 2 through the transmission belt 21.

[0108] Since one end of the driving assembly 5 is connected with the drum through the transmission belt 21 and the other end is connected with the fan, when the rotating speed of the drum 2 and the fan is adjusted, they can only be adjusted synchronously. When it is desired to control the drum 2 to rotate rapidly, the rotating speed of the output shaft 511 is increased, but the rotating speed of the fan cannot be reduced at the same time, and the fan can only be increased in rotating speed synchronously with the drum 2 and the output shaft 511. In order to control the rotating speed of the drum 2 and the fan separately, the fan is controlled by the first motor alone, and the second motor 51 only controls the rotation of the drum 2. In addition, since there are manufacturing and installation tolerances of the drum 2, the geometric center of the drum 2 deviates from the original rotating center, so that the drum 2 generates circular runout, and further generates exciting force to the second motor 51, causing the motor to vibrate and generate noise.

[0109] Therefore, the balancing assembly 513 is additionally arranged on the output shaft 511 of the second motor 51, which compensates the vibration generated by the output shaft 511 when the output shaft 511 rotates. By reducing the vibration of the output shaft 511, the noise caused by the vibration can be effectively reduced, and the use experience of the clothes treatment device 100 is improved. In addition, since the output shaft 511 is connected with the drum 2 through the transmission belt 21, the transmission belt 21 is connected to the output shaft 511 through the belt pulley 22 arranged on the output shaft 511. By arranging the balancing assembly 513 to compensate the vibration, the vibration of the belt pulley 22 is reduced, the relative displacement of the transmission belt 21 on the belt pulley 22 due to the vibration is further reduced, and even the possibility of falling off is reduced. The wear of the transmission belt 21 and the belt pulley 22 caused by the vibration is also reduced, which further ensures the stability of the operation of the clothes treatment device 100, helps to prolong the overall service life of the clothes treatment device 100, reduces the maintenance cost and the frequency of replacing the equipment of the user, and improves the performance-price ratio of the device.

[0110] The balancing assembly 513 is arranged on the output shaft 511 and can rotate with the output shaft 511. The balancing assembly 513 can increase the moment of inertia of the output shaft 511 when the output shaft 511 rotates. In this way, on the premise of realizing independent control of the rotation of the fan and the drum 2, the increase of the moment of inertia helps to improve the stability of the rotation of the output shaft 511, and further reduces the vibration that may be generated during the rotation of the output shaft 511, reduces the noise generated during the operation of the clothes treatment device 100, and prevents the transmission belt 21 from slipping or even falling off on the belt pulley 22 due to the vibration.

[0111] In some embodiments, in combination with Figure 4The balancing assembly 513 comprises a first balancing piece 5131 arranged on the output shaft 511. The center of mass of the first balancing piece 5131 is located on the axis of the output shaft 511. When the output shaft 511 rotates, the rotation stability of the output shaft 511 is effectively improved, and the vibration generated by the output shaft 511 is reduced.

[0112] In some embodiments, the first balancing piece 5131 is arranged on the output shaft 511. Figure 4 The first balancing piece 5131 is in a ring structure, and the first balancing piece 5131 is sleeved on the output shaft 511. The center of the first balancing piece 5131 is located on the axis of the output shaft 511.

[0113] The ring structure makes the mass distribution of the first balancing piece 5131 more uniform in the circumferential direction. When the output shaft 511 rotates, the force in the circumferential direction of the first balancing piece 5131 is more uniform, and the centrifugal force of each part in the circumference is more uniform. Compared with irregular shapes, it is more conducive to maintaining the stability of rotation, can more accurately compensate for the vibration of the output shaft 511, reduce the vibration generated by the rotation of the output shaft 511, and further reduce noise and the possibility of displacement of the transmission belt 21 relative to the pulley 22.

[0114] In some embodiments, the second motor 51 is a fixed-frequency AC motor.

[0115] The fixed-frequency AC motor has a lower cost, thereby reducing the cost of the entire machine. The fixed-frequency AC motor has stable speed and reliable operation performance, can ensure the stability and efficiency of the work load, can provide stable power output, and ensure the normal operation of the device. The fixed-frequency AC motor has a relatively simple structure and high efficiency, and has a high energy conversion efficiency. For the clothes treatment device 100 that operates for a long time, energy costs can be saved. The maintenance and repair costs are relatively low, the service life is long, and the maintenance costs and downtime can be reduced.

[0116] In some embodiments, the clothes treatment device 100 is a 110L platform. When the motor is a fixed-frequency AC motor, the first balancing piece 5131 is added to simulate and test the maximum amplitude of the vibration generated by the second motor 51 and the pulley 22.

[0117] The base and inner section of the second motor 51 are kept stationary. A force of 100N is applied to the output shaft 511 to represent the comprehensive eccentric force, including eccentricity factors. With the output shaft 511 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 masses of the first balancer 5131 are applied sequentially: 100g, 200g, 300g, 400g, 500g, 600g, 700g, 800g, 900g, and 1000g. The simulation results are shown in Table 1.

[0118]

[0119] Table 1

[0120] 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 embodiment. 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 stability of the clothing processing device's operation, 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.

[0121] In some embodiments, the mass of the first balancing component 5131 can be determined to be 150g to 400g, depending on the actual working conditions.

[0122] Furthermore, 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.

[0123]

[0124] 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.

[0125] The main function of the first balancing piece 5131 is to compensate the vibration generated when the output shaft 511 rotates. According to actual working tests, if the mass is less than 150 g, the compensation amount of the vibration of the output shaft 511 is small, and the vibration of the belt pulley 22 on the output shaft 511 is still obvious, which may cause displacement of the transmission belt 21 on the belt pulley 22, thereby affecting the stability and service life of the entire device. If the mass of the first balancing piece 5131 exceeds 400 g, the first balancing piece 5131 has a large volume and may interfere with the inner wall of the base of the clothes treatment device 100. Therefore, the first balancing piece 5131 with a mass of 150 g to 400 g can achieve a good vibration compensation effect in the limited installation space, thereby effectively improving the rotation stability of the output shaft 511.

[0126] In some embodiments, the first balancing piece 5131 is made of steel.

[0127] Steel is a high-strength material that can withstand a large stress and deformation. Steel has a large density, and the same volume can be used to make a first balancing piece 5131 with a larger mass, thereby achieving a better vibration compensation effect. In the clothes treatment device 100, the first balancing piece 5131 needs to compensate the vibration generated when the output shaft 511 rotates. The first balancing piece 5131 made of steel can provide sufficient strength and durability to ensure that it will not be easily damaged during long-term use. Steel generally has a certain corrosion resistance, which can prolong the service life of the first balancing piece 5131 and reduce the frequency of maintenance and replacement. In addition, the selection of steel as the material of the first balancing piece 5131 can effectively control the production cost while ensuring the product quality.

[0128] In some embodiments, the thickness of the first balancing piece 5131 is 3 mm to 7 mm. If the thickness of the first balancing piece 5131 is less than 3 mm, the first balancing piece 5131 cannot provide sufficient strength and stability and is prone to deformation, which affects the service life of the device. In addition, in order to ensure that the mass of the first balancing piece 5131 is large enough, the outer diameter of the first balancing piece 5131 needs to be set larger. Since the second motor 51 is usually arranged on the base, the base usually has components such as the heat supply system 4 and the fan assembly of the air duct assembly 3, so the space of the base is limited. The outer diameter of the first balancing piece 5131 that is too large may interfere with the inner wall of the base. If the thickness of the first balancing piece 5131 is greater than 7 mm, it may also interfere with the inner wall of the base of the clothes treatment device 100. Therefore, the thickness is set to 3 mm to 7 mm, so that the first balancing piece 5131 can achieve a good vibration compensation effect under the premise that other components on the base have sufficient installation space, thereby effectively improving the rotation stability of the output shaft 511.

[0129] In some embodiments, the outer diameter of the first balancing member 5131 is 60-100 mm according to actual working conditions.

[0130] According to the above formula (1) and the following rotational inertia formula (2), and combined with actual working conditions, it can be concluded that when the outer diameter of the first balancing member 5131 is less than 60 mm, the rotational inertia of the first balancing member 5131 is too small to effectively compensate for the vibration of the output shaft 511, and the vibration of the pulley 22 on the output shaft 511 is still relatively obvious, and the transmission belt 21 will produce displacement on the pulley 22 or even fall off, thereby affecting the stability and service life of the entire device. If the outer diameter of the first balancing member 5131 exceeds 100 mm, the first balancing member 5131 has a large volume, and since the second motor is usually arranged on the base, the base usually also has other components (such as the fan assembly of the heating system 4 and the air duct assembly 3), so the space of the base is limited, and the first balancing member 5131 will interfere with the inner wall of the base. Therefore, the first balancing member 5131 with an outer diameter of 60-100 mm can achieve a better vibration compensation effect in a limited installation space, effectively improving the rotational stability of the output shaft 511.

[0131] I = mr3 2 (2)

[0132] Wherein, I is the rotational inertia of the first balancing member 5131 rotating around 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.

[0133] In some embodiments, combined with Figure 4 and Figure 8 , Figure 8 is a 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, the second balancing member 5132 is fixed relative to the output shaft 511, the second balancing member 5132 has a containing space 5132a inside, and the containing space 5132a contains a balancing medium. When the output shaft 511 rotates, the balancing medium can move in the containing space 5132a to compensate for the vibration generated by the output shaft 511.

[0134] 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. 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 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.

[0135] 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.

[0136] 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.

[0137] 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) The higher density can provide greater inertial force to compensate for vibration when the output shaft 511 rotates, especially when dealing with larger vibration amplitudes or vibrations generated at higher speeds. By adjusting the saltwater concentration to change the density, the balancing assembly 513 can more accurately adapt to the operating state of the device. Moreover, the preparation cost of saltwater is low, and the raw materials (salt and water) are easy to obtain, thereby reducing production costs.

[0138] In the second possible implementation, the silicone oil has high chemical stability and is not prone to chemical reactions with other substances. The silicone oil will not deteriorate or lose its balancing effect due to reactions with the materials of the balancing assembly 513 (such as the container wall, etc.), which helps to maintain the long-term stable operation of the clothes treatment device 100 and reduces the decline in vibration compensation ability due to changes in the balancing medium. The silicone oil also has certain lubricity, which can reduce the friction between internal components. When the output shaft 511 rotates, the distribution of silicone oil in the second balancing member 5132 not only compensates for vibration but also reduces energy loss and noise due to component friction, which helps to improve the overall efficiency and service life of the device. 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.

[0139] In the third possible implementation, the saltwater and silicone oil are used in combination. Not only can the overall density of the balancing medium be appropriately adjusted by using two liquids with different densities to improve the flowability of the balancing medium, but also the balancing medium has high chemical stability, making its movement in the balancing assembly 513 smoother, which can further improve its ability to compensate for vibration and relatively reduce the production cost of the balancing medium when it is silicone oil.

[0140] In some embodiments, the volume of the liquid medium occupies 30% to 50% of the volume of the accommodation space 5132a. Such a liquid volume ratio can make the distribution and flow state of the liquid medium in the accommodation space 5132a optimal, so that the liquid can adjust the position in time to compensate for the vibration when the output shaft 511 rotates.

[0141] When the volume of the liquid is too small, the balancing medium distributed in the accommodation space 5132a is too little to effectively compensate for the vibration, and the effect of reducing the vibration is not obvious. That is, when the volume of the liquid is less than 30%, the mass of the liquid is not enough, and the balancing medium cannot balance the vibration of the output shaft 511 of the motor in the clothes treatment apparatus 100. If the volume of the liquid is too large, the movable range of the liquid medium inside is too small, the effect of automatically adjusting the center of mass position according to the eccentric position of the output shaft 511 is not good, and the vibration cannot be effectively compensated. That is, when the volume of the liquid is greater than 50%, the movement space of the liquid is not enough, and the vibration of the output shaft 511 of the motor in the clothes treatment apparatus 100 cannot be effectively compensated.

[0142] Preferably, the volume of the liquid medium accounts for 40% of the volume of the accommodation space 5132a.

[0143] While ensuring the cost, the liquid medium with a volume of 40% can better distribute and flow in the accommodation space 5132a, and the liquid can timely adjust the position to compensate for the vibration generated when the output shaft 511 rotates.

[0144] In some embodiments, in combination Figure 10 The balancing medium includes a plurality of solid particles, Figure 10 When the balancing medium is a solid particle, the cross-sectional view of the second balancing member 5132 (including the output shaft 511) is shown. When the output shaft 511 rotates, the plurality of solid particles can collide with each other, and the solid particles and the side wall of the second balancing member 5132 can also collide with each other. The vibration energy generated by the output shaft 511 is converted into heat energy generated by collision to compensate for the vibration generated by the output shaft 511.

[0145] In some embodiments, the solid particles include at least one of iron sand, lead particles, or steel balls. The shapes of the iron sand, lead particles, and steel balls are relatively regular (approximately spherical). Such regular shapes make them have good fluidity in the accommodation space 5132a. When the output shaft 511 rotates, these solid particles can move smoothly in the accommodation space 5132a, and these three kinds of solid particles can all generate heat energy by collision to effectively compensate for the vibration.

[0146] In a first possible implementation, the solid particles are iron sand. The iron sand has a relatively large density, and when colliding with other particles or the side wall of the second balancing member 5132, it can more effectively convert the vibration energy of the output shaft 511 into heat energy due to its relatively large mass under the same change in velocity according to the law of conservation of energy. When the output shaft 511 generates a certain vibration speed, the momentum change of the iron sand particles when colliding is large, so that the vibration energy can be more fully absorbed and converted, and the vibration of the output shaft 511 is better compensated. Moreover, the iron sand particles are relatively irregular in shape but hard in texture, and are not easily worn or deformed during long-term use, so that the distribution state of the iron sand in the accommodation space 5132a can be maintained, and the vibration energy can be continuously and stably converted. As a relatively common and low-cost material, the use of iron sand as solid particles can effectively control the production cost while meeting the functional requirements for compensating the vibration of the output shaft 511.

[0147] In a second possible implementation, the solid particles are lead particles. The lead particles also have a relatively high density, and when colliding with other particles or the side wall of the second balancing member 5132, they can effectively absorb the vibration energy of the output shaft 511 and convert it into heat energy. The lead has a relatively soft texture, which makes it have a certain damping effect when colliding. It can slow down the collision speed between particles and between particles and the side wall, so that the energy conversion process is more gentle, reducing the impact on the structure of the balancing assembly 513 that may be caused by violent collisions, thereby prolonging the service life of the balancing assembly 513, and also stably compensating for the vibration of the output shaft 511.

[0148] In a third possible implementation, the steel balls have a relatively high hardness and are not easily worn during long-term mutual collisions and collisions with the side wall. This enables the steel balls to maintain their shape and mass properties for a relatively long period of time, continuously and stably compensating for the vibration of the output shaft 511 and reducing the risk of performance degradation of the balancing assembly 513 due to particle wear. The high strength of the steel balls also makes them less likely to deform or be damaged when subjected to relatively large vibration impact forces. In the case of relatively large vibration of the output shaft 511, the steel balls can still effectively participate in the energy conversion process, ensuring the compensation effect of the vibration and maintaining the stable operation of the clothes treatment device 100.

[0149] In some embodiments, the total volume of the solid particles accounts for 10% to 90% of the volume of the accommodation space 5132a. Such a volume ratio of the solid particles can enable the distribution and flow state of the solid particles in the accommodation space 5132a to be optimal, so that the solid particles can generate heat energy through relatively full friction and collision when the output shaft 511 rotates, compensating for the vibration of the output shaft 511.

[0150] If the total volume of the solid particles accounts for less than 10% of the volume of the accommodation space 5132a, the collision opportunity between them is reduced, and thus the efficiency of converting vibration energy into heat energy is reduced, which cannot be effectively compensated when the output shaft 511 of the motor in the clothes treatment device 100 vibrates, resulting in a weakened damping effect; if the total volume of the solid particles accounts for more than 90% of the volume of the accommodation space 5132a, the movement space of the solid particles is not enough, and too many solid particles will hinder the flow of the balancing medium, and cannot achieve sufficient friction and collision between the particles, thereby reducing the energy conversion efficiency, which cannot be effectively compensated when the output shaft 511 of the motor in the clothes treatment device 100 vibrates, affecting the damping effect.

[0151] In some embodiments, in combination with Figures 4 to 6 , Figure 5 For Figure 4 The cross-sectional view at A-A in FIG. 13, the second balancing member 5132 is a ring structure, and the accommodation space 5132a is an annular space. The center of the ring structure is located on the axis of the output shaft 511. The ring structure can be uniformly distributed around the output shaft 511, and the balancing medium in the annular space can move uniformly when the output shaft 511 rotates, thereby more stably and uniformly compensating for the vibration generated by the output shaft 511.

[0152] In some embodiments, in combination with Figure 8 and Figure 10 The second balancing member 5132 further comprises a pushing member 51321, which is arranged in the accommodation space 5132a and fixedly connected to the inner wall of the second balancing member 5132. When the second balancing member 5132 rotates, the pushing member 51321 can apply a pushing force to the balancing medium in the direction of rotation, effectively enhancing the damping effect of the balancing assembly 513.

[0153] When the pushing member 51321 rotates with the second balancing member 5132, it applies a pushing force to the balancing medium in the direction of rotation. For liquid medium, the pushing force of the pushing member 51321 can provide a pushing force for the liquid medium to flow better in the accommodation space 5132a, and the liquid medium can more quickly adjust its own distribution so that when the rotation speed of the output shaft 511 exceeds the low-frequency resonance point of the suspension system, the mass center of the liquid medium after the system is eccentric from the mass center, reaches the position in the opposite direction more quickly, thereby reducing the eccentric equivalent more quickly and improving the damping effect.

[0154] For solid particle balancing medium, the pushing force of such pushing member 51321 can promote more frequent and more violent collisions between solid particles and between solid particles and the wall of the accommodation space 5132a, which means that more vibration energy can be converted into heat energy, thereby enhancing the ability to convert the vibration energy of the output shaft 511 into heat energy and effectively compensating for the vibration generated by the output shaft 511.

[0155] In some embodiments, in combination with Figure 11 , Figure 11 For Figure 7 The cross-sectional view of the second balancing member 5132, the pushers 51321 are multiple, and the multiple pushers 51321 are distributed along the circumference of the second balancing member 5132. This allows each part of the second balancing member 5132 to have a pusher 51321 to apply a pushing force to the balancing medium during the rotation of the second balancing member 5132, and the balancing medium receives a more uniform pushing force.

[0156] For liquid medium, each liquid medium between the pushers 51321 can receive the same pushing force, which can adjust the distribution of the liquid medium more quickly, so that when the output shaft 511 rotates at high speed, the mass center of the liquid medium and the mass center after the system is eccentric, more quickly reach the position with a phase difference of 180 degrees, and then reduce the eccentric equivalent amount more quickly, improve the damping effect.

[0157] For solid particles, each solid particle between the pushers 51321 can receive a uniform pushing force, and the solid particles collide with each other or the pushers 51321 and the inner wall, which can convert vibration energy into friction heat energy more quickly and better. The uniform pushing force makes the collision between the particles more uniform in the circumferential direction, and there is no situation that local collision is too violent and other parts of the collision are insufficient, thereby improving the overall energy conversion efficiency, more effectively converting the vibration energy of the output shaft 511 into heat energy and other forms of energy, and enhancing the damping effect.

[0158] In some embodiments, in combination with Figure 8 , Figure 10 and Figure 11 The pusher 51321 is a plate structure, and the pusher 51321 extends along the radial direction of the second balancing member 5132, and the thickness direction of the plate structure extends along the circumferential direction of the annular structure of the second balancing member 5132.

[0159] The plate structure of the pusher 51321 can more effectively apply a pushing force to the balancing medium. Since it extends along the radial direction of the second balancing member 5132, it can cover a larger area in the radial direction, 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, and can improve the compensation effect of the balancing assembly 513 on the vibration of the output shaft 511, especially when the rotation 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.

[0160] In some embodiments, in combination with Figure 11The plurality of push members 51321 divide the accommodation space 5132a into a plurality of subspaces, the plurality of subspaces are arranged along the circumference of the second balancing member 5132, and the push member 51321 is provided with a communication hole 51322, and the communication hole 51322 communicates two adjacent subspaces in the circumferential direction.

[0161] The liquid medium can flow freely in the plurality of subspaces through the communication hole 51322, and such partitioned flow can avoid disordered flow of the liquid in the accommodation space 5132a. The existence of the communication hole 51322 can ensure the ordered flow of the liquid between different subspaces along the circumference of the second balancing member 5132, and help to more accurately control the flow path of the liquid, so that the liquid can more effectively adjust its distribution to compensate for vibration according to the vibration of the output shaft 511.

[0162] In some embodiments, in combination with Figure 8 and Figure 9 , Figure 9 for Figure 8 The local enlarged view of B in FIG. 13B shows that the communication hole 51322 includes a first communication hole 51322a, which is arranged on the side of the push member 51321 close to the inner diameter of the balancing member.

[0163] In some embodiments, the communication hole 51322 further includes a second communication hole 51322b, which is arranged on the side of the push member 51321 close to the outer diameter of the balancing member.

[0164] When the output shaft 511 rotates at a low speed, the centrifugal force acting on the liquid medium is small, and the liquid medium adjusts its distribution in the accommodation space 5132a through the first communication hole 51322a. When the output shaft 511 rotates at a high speed, the centrifugal force acting on the liquid medium is large, and the liquid medium adjusts its distribution in the accommodation space 5132a through the second communication hole 51322b. The different positions of the first communication hole 51322a and the second communication hole 51322b will cause the liquid to form a specific flow direction in the accommodation space 5132a (i.e. from the inner diameter side of the balancing member to the outer diameter side of the balancing member). During the process of the output shaft 511 changing from low speed to high speed, the liquid tends to flow from the inner diameter side (where the first communication hole 51322a is located) to the outer diameter side (where the second communication hole 51322b is located) due to the centrifugal force. Such directional flow helps to more accurately adjust the distribution of the liquid in the accommodation space 5132a to adapt to the eccentric vibration of the output shaft 511, thereby effectively compensating for the vibration.

[0165] Compared with the single communication hole 51322 or the design without the communication hole 51322 in a specific position, the arrangement of the communication holes 51322 in different positions can more accurately control the flow path of the liquid, improve the response speed and compensation effect of the balancing assembly 513 on vibration.

[0166] In some embodiments, in combination Figure 9 The projection area of the first communication hole 51322a along the radial direction of the output shaft 511 is greater than the projection area of the second communication hole 51322b along the radial direction of the output shaft 511. When the output shaft 511 rotates at a low speed, the flow rate of the liquid medium passing through the first communication hole 51322a is also slow, and when the output shaft 511 rotates at a high speed, the flow rate of the liquid medium passing through the second communication hole 51322b is fast, so the area of the first communication hole 51322a is greater than the area of the second communication hole 51322b, thereby ensuring that the flow rates of the liquid medium passing through the first communication hole 51322a and the second communication hole 51322b are not greatly different, so that the liquid medium can flow in each sub-space through the communication holes 51322 at a similar flow rate regardless of whether the output shaft 511 rotates at a low speed or a high speed, thereby ensuring the response speed and compensation effect of the balancing assembly 513 on vibration.

[0167] In some embodiments, in combination Figure 9 The first communication hole 51322a has a first preset length along the axial direction of the output shaft 511 and a first preset width along the radial direction of the output shaft 511.

[0168] In some embodiments, the second communication hole 51322b has a second preset length along the axial direction of the output shaft 511 and a second preset width along the radial direction of the output shaft 511.

[0169] 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.

[0170] Since the first communication hole 51322a and the second communication hole 51322b are arranged along the radial direction of the second balancing member 5132 on the pusher 51321, the space in the radial direction is limited, while the space in the axial direction of the second balancing member 5132 is relatively sufficient. Under the premise that the first preset width and the second preset width along the radial direction are the same, the first preset length is greater than the second preset length, so that the area of the first communication hole 51322a is greater than the area of the second communication hole 51322b, thereby ensuring that the liquid medium can flow in each sub-space through the communication holes 51322 at a similar flow rate regardless of whether the output shaft 511 rotates at a low speed or a high speed, thereby ensuring the response speed and compensation effect of the balancing assembly 513 on vibration.

[0171] In some embodiments, in combination Figure 8and Figure 9 The communication hole 51322 further comprises a third communication hole 51322c, which is arranged between the first communication hole 51322a and the second communication hole 51322b and penetrates the first communication hole 51322a and the second communication hole 51322b respectively.

[0172] In the process of changing from low-speed rotation to high-speed rotation, the liquid medium flows from the first communication hole 51322a to the second communication hole 51322b, and the liquid medium can also flow between the subspaces through the third communication hole 51322c, which does not hinder the liquid medium from passing between the first communication hole 51322a and the second communication hole 51322b, ensuring that the liquid medium can smoothly adjust its own distribution in the accommodation space 5132a.

[0173] In some embodiments, in combination with Figure 10 and Figure 18 , Figure 18 For Figure 10 The second balancing member 5132 comprises an inner ring wall 51323, which is arranged around the output shaft 511.

[0174] In some embodiments, the second balancing member 5132 further comprises an inner ring wall 51323, and an outer ring wall 51324 is arranged around the inner ring wall 51323, and the accommodation space 5132a is formed between the outer ring wall 51324 and the inner ring wall 51323.

[0175] In some embodiments, the pushing member 51321 is connected with the outer ring wall 51324, and the pushing member 51321 is arranged spaced apart from the inner ring wall 51323.

[0176] When the balancing medium is solid particles, the plurality of solid particles can flow between the plurality of subspaces through the space between the pushing member 51321 and the inner ring wall 51323, so that the solid particles in each subspace can also collide with each other to generate heat energy, and more fully compensate for the vibration generated by the output shaft 511.

[0177] In some embodiments, in combination with Figure 11 The second balancing member 5132 is annular, and a plurality of second balancing members 5132 are sequentially arranged along the radial direction of the output shaft 511, and the innermost second balancing member 5132 is directly connected with the output shaft 511.

[0178] In this way, when only the second balance member 5132 is arranged on the output shaft 511, the limited space in the housing 1 is effectively utilized under the premise of ensuring the annular structure of the second balance member 5132, so that the outermost second balance ring can be fixed on the output shaft 511, and each second balance member 5132 can compensate the vibration. When the output shaft 511 rotates at a high speed, the multiple second balance members 5132 work together to better suppress the relatively large vibration generated during high-speed rotation, thereby improving the stability of the entire clothes treatment device 100.

[0179] Moreover, if one of the balance members fails (for example, the internal balance medium leaks or the structure is damaged), the other balance members can still compensate the vibration, thereby reducing the risk of serious vibration problems of the entire clothes treatment device 100 caused by the failure of a single balance member, improving the reliability and stability of the device, prolonging the service life of the device, and facilitating maintenance and repair.

[0180] In some embodiments, in combination with Figure 11 The second balance member 5132 further includes multiple separation rings 51325, the multiple separation rings 51325 are arranged in the accommodation space 5132a, the centers of the multiple separation rings 51325 are located on the axis of the output shaft 511, the multiple separation rings 51325 are sequentially arranged along the radial direction of the output shaft 511, and adjacent two separation rings 51325 are arranged at intervals to separate the accommodation space 5132a into multiple annular spaces, and the multiple annular spaces are respectively filled with balance medium.

[0181] In this way, the second balance member 5132 has an integrated structure, which is more compact and simple in design, reduces the cumbersome steps in the installation process, reduces the probability of errors, significantly improves the construction efficiency, and reduces the number of parts. This not only simplifies the installation process, but also reduces the connection points between parts, thereby reducing the risk of failure caused by loose or damaged connection points. The flow range of the balance medium in each annular space is limited, so that the balance medium moves orderly in the respective annular space to compensate the vibration, thereby enhancing the stability of the entire balance assembly 513.

[0182] It can be understood that, taking the second balance member 5132 with three annular spaces (three-cavity balance member) or the three second balance members 5132 working together as an example, the vibration compensation effect of the second balance member 5132 with only one annular space (single-cavity balance member) on the output shaft is different from that of the first balance member 5131. The maximum amplitude of the second motor 51 and the pulley 22 caused by vibration is simulated and tested according to the three cases.

[0183] In some embodiments, the laundry treatment device 100 is a 110L platform, the motor is a fixed frequency AC motor, the constraint foot and the inner cross section are applied with a force of 200N on the motor shaft, and the comprehensive eccentric force is represented by the eccentric factor.

[0184] When the output shaft 511 is in a high-speed rotating state, the second balance member 5132 and the output shaft 511 are in an eccentric phase of 180 degrees. Considering that the second balance member 5132 has only one annular space and is filled with brine with the same volume ratio, the offset amount of the center of mass of the second balance member 5132 is set to be 0.5mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, and 4.0mm in sequence, and the maximum amplitude of the second motor 51 and the pulley 22 caused by vibration is obtained. At the same time, for comparison and analysis, the center of mass of the balance member is set to be offset by 4.0mm, and the single-cavity balance member and the three-cavity balance member are both filled with brine. The maximum amplitude of the second motor 51 and the pulley 22 caused by vibration is obtained by simulation, and the working conditions of the above three different balance members are analyzed. According to the above two simulation experiments, Table 2 is obtained.

[0185]

[0186] Table 2

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

[0207] In some embodiments, the connecting bracket 5133 is made of a hard material.

[0208] The connecting bracket 5133 made of a hard material can provide better structural stability, ensuring that the connecting bracket 5133 can bear the corresponding force and vibration during the rotation of the output shaft 511, reducing the possibility of deformation of the connecting bracket 5133 during long-term use, and maintaining the stability of the overall structure of the balancing assembly 513.

[0209] In some embodiments, the connecting bracket 5133 is a plastic part.

[0210] Plastic materials generally have a lighter mass, which helps to reduce the overall weight of the clothes treatment device 100. Plastic materials also have good corrosion resistance and can resist the erosion of chemicals and moisture that may be encountered in daily use, thereby prolonging the service life of the connecting bracket 5133. Plastic materials can be molded into various complex shapes through molding processes such as injection molding, which provides greater flexibility for the design of the connecting bracket 5133. In addition, plastic materials generally have lower costs, and the use of plastic connecting brackets 5133 can reduce production costs, thereby reducing product prices and improving market competitiveness.

[0211] In some embodiments, the first balancing piece 5131 is made of metal and the second balancing piece 5132 is made of rubber.

[0212] The first balancing piece 5131 made of metal generally has a higher density and rigidity, which can provide stable mass distribution and help compensate for vibration when the output shaft 511 rotates. The second balancing piece 5132 made of rubber has good elasticity and damping characteristics, which can absorb and dissipate vibration energy, further enhancing the balancing effect. The combination of the two can take advantage of their respective strengths in different vibration frequency ranges, improving overall balancing performance. In addition, while meeting performance requirements, the material cost and manufacturing process feasibility are considered. This combination may have more economic advantages than a balancing assembly 513 made of a single material, and it is also convenient for production and manufacturing.

[0213] In some embodiments, the connecting bracket 5133 is made of a hard material. Figure 7 andFigure 14 , Figure 7 Another structural schematic view of the second balancing member 5132 (including the output shaft 511) disclosed in the embodiments of the present application is shown in the following, Figure 14 is an exploded view of Figure 7 The second motor 51 further comprises a limiting portion 5111 arranged on the output shaft 511, which is used to limit the movement of the first balancing member 5131 along the circumference of the output shaft 511.

[0214] In some embodiments, the second motor 51 further comprises a matching portion 5112 arranged on the inner hole wall of the first balancing member 5131, which cooperates with the limiting portion 5111 to enable the output shaft 511 to drive the first balancing member 5131 to rotate, so that the first balancing member 5131 can compensate for the vibration generated by the output shaft 511 during the rotation of the output shaft 511, effectively reducing the noise caused by the vibration and reducing the possibility of the transmission belt 21 generating relative displacement on the belt pulley 22 due to vibration or even falling off, thereby prolonging the service life of the equipment and reducing maintenance and replacement costs.

[0215] In this way, the output shaft can drive the first balancing member to rotate without adding other parts, simplifying the assembly process.

[0216] In some embodiments, in combination with Figure 7 and Figure 14 The limiting portion 5111 is a flat portion formed on the outer circumferential surface of the output shaft 511, and the matching portion 5112 is a flat portion formed on the inner hole wall of the first balancing member 5131, which is in contact with the flat portion to prevent the first balancing member 5131 from rotating relative to the output shaft 511. Among them, the flat portion usually refers to a flat part on the shaft workpiece, which is different from the circular cross-section of the shaft, and it is flat. Flat parts are very common in mechanical processing, especially on shaft parts that need to be connected or transmitted with other parts. For example, on some transmission shafts, the flat portion can be used for key connection with other parts, or used as a positioning surface.

[0217] This structure ensures the effective transmission of power from the output shaft 511 to the first balancing member 5131, avoids energy loss caused by relative rotation, and makes the structure of the entire drive assembly 5 more compact and reliable. In the operation of the clothes treatment device 100, it can ensure that the balancing assembly 513 works cooperatively with the output shaft 511 to accurately compensate for the vibration generated by the output shaft 511.

[0218] In some embodiments, in combination with Figure 4 and Figure 5The second motor 51 further comprises a motor shell 512, and the output shaft 511 penetrates through the motor shell 512. The output shaft 511 comprises a first end 511a and a second end 511b, and the first end 511a and the second end 511b respectively extend out of two opposite side walls of the motor shell 512. The first end 511a is in transmission connection with the roller 2, and the balancing assembly 513 is arranged at the second end 511b.

[0219] The two ends of the output shaft 511 extend out of the motor shell 512, and the balancing assembly 513 is additionally arranged at the second end 511b, so that the forces on the two ends of the output shaft 511 are more balanced when the output shaft 511 rotates. The balancing assembly 513 can balance the center of gravity of the output shaft 511, further reduces the vibration of the output shaft 511, and improves the stability of the driving assembly 5.

[0220] In some embodiments, in combination with Figure 7 and Figure 14 The second motor 51 further comprises an axial positioning structure 514 arranged between the balancing assembly 513 and the output shaft 511 to prevent the balancing assembly 513 from moving axially relative to the output shaft 511.

[0221] The axial positioning structure 514 can ensure that the position of the balancing assembly 513 on the output shaft 511 is fixed, preventing displacement in the axial direction. Especially when the output shaft 511 rotates at high speed, the axial positioning structure 514 can reduce the instability of the compensation vibration effect caused by the movement of the balancing assembly 513, thereby improving the stability and reliability of the entire driving assembly 5.

[0222] In some embodiments, in combination with Figure 7 and Figure 14 The axial positioning structure 514 comprises a shaft shoulder 5141 arranged on the output shaft 511.

[0223] In some embodiments, the axial positioning structure 514 further comprises a stopper 5142 arranged on the output shaft 511 in a detachable manner, and the balancing assembly 513 is arranged between the shaft shoulder 5141 and the stopper 5142.

[0224] The shaft shoulder 5141 is generally where the shaft diameter changes, forming a stepped shape. It can be a portion of the shaft where the diameter suddenly increases or decreases during machining, such as turning. In this embodiment, the output shaft 511 is machined to have a portion where the diameter suddenly decreases to accommodate the balancing assembly 513, so that one side of the balancing assembly 513 abuts the larger-diameter side in the axial direction. The other side of the balancing assembly 513 abuts the stopper 5142, and the shaft shoulder 5141 cooperates with the stopper 5142 to provide precise axial positioning of the balancing assembly 513. This allows the balancing assembly 513 to be accurately installed at a predetermined position on the output shaft 511, ensuring that it functions properly to compensate for vibrations during rotation of the output shaft 511. Moreover, by flexibly disassembling the stopper 5142, the balancing assembly 513 can be more easily disassembled.

[0225] In some embodiments, the stopper 5142 can be a nut that is threadedly connected to the shaft end of the output shaft 511. The nut is a common and standardized fastener that is easy to install and disassemble, facilitating regular maintenance or replacement of damaged components (such as the stopper 5142, the balancing assembly 513, etc.). The nut has good fastening performance and cooperates with the shaft shoulder 5141 to provide reliable axial positioning, preventing the balancing assembly 513 from shifting axially during operation.

[0226] In some embodiments, in combination with Figure 4 The balancing assembly 513 includes a first balancing member 5131, which is disposed on the output shaft 511.

[0227] In some embodiments, the balancing assembly 513 further includes an absorption member (not shown in the figure) disposed on the output shaft 511. The absorption member can be made of sound-absorbing material and / or water-absorbing material, i.e., it can be made of sound-absorbing material, water-absorbing material, or both.

[0228] The addition of the first balancing member 5131 to the output shaft 511 of the motor effectively reduces vibrations. The addition of the absorption member, which is made of sound-absorbing material, can absorb the noise generated by the second motor 51, further reducing the noise of the entire machine. The absorption member, which is made of water-absorbing material, can absorb the liquid water condensed from the water vapor around the second motor 51 and can fling off the absorbed water during high-speed rotation of the output shaft 511, improving the collection efficiency of the condensed water.

[0229] In some embodiments, the absorption member is made of porous material.

[0230] The porous material has good sound absorption performance, which can effectively absorb the noise generated during the operation of the device, providing a more quiet use environment. This is particularly important for laundry treatment devices 100 in a home environment, as users generally want to be undisturbed by noise when using these devices.

[0231] The porous material can also absorb moisture, maintaining a dry environment inside the device, thereby improving the performance and lifespan of the device. By reducing noise and absorbing moisture, the absorbing member of porous material can effectively improve the stability and safety of the drive assembly 5.

[0232] In some embodiments, the material of the absorbing member includes sponge, polyurethane foam, or foam rubber.

[0233] When the absorbing member is a sponge, the sponge is a porous material that can effectively absorb sound waves and reduce noise propagation. The sponge can also absorb a large amount of moisture, which is useful for absorbing moisture around the second motor 51 and maintaining a dry working environment. In addition, the elasticity and porosity of the sponge also provide a certain damping effect. When the output shaft 511 vibrates and generates a certain impact, the sponge can be compressed to reduce the impact force.

[0234] When the absorbing member is polyurethane foam, the polyurethane foam has excellent sound absorption performance and can effectively absorb and isolate noise. The elasticity and plasticity of the polyurethane foam make it a good shock-absorbing and cushioning material, protecting the first balance member 5131 from impact and vibration.

[0235] When the absorbing member is foam rubber, the porous structure of the foam rubber provides good sound absorption and insulation effects. The foam rubber also has elasticity and plasticity, achieving good shock-absorbing effects.

[0236] In some embodiments, the absorbing member is in a ring structure.

[0237] The ring structure allows the absorbing member to be evenly distributed on the output shaft 511, so that the sound absorption and / or water absorption effects of the absorbing member are the same in the circumferential direction of the output shaft 511. The ring structure ensures that the absorbing member remains balanced during rotation, helping to reduce displacement and vibration caused by uneven stress on the absorbing member, thereby reducing noise and improving the stability of the device.

[0238] The ring structure can uniformly increase the contact area between the absorbing member and air or moisture, which helps to improve the efficiency of the absorbing member in absorbing noise and moisture, thereby improving the overall care effect.

[0239] In some embodiments, in combination Figure 4 The absorbing member is arranged in the axial direction with the first balance member 5131, and the absorbing member is connected to the first balance member 5131.

[0240] Since the absorbent is flexible and not convenient to be directly fixed to the output shaft 511, the absorbent is fixed to the first balancing component 5131, which has a larger contact area and forms a more stable structure. During the operation of the garment handling device 100, especially when rotating at high speed or when the load changes, this connection method can enhance the overall stability of the balancing component 513.

[0241] The absorber and the first balancing component 5131 are axially fitted, which improves the noise absorption effect of the absorber. This ensures that it can absorb the noise generated by the vibration of the output shaft 511, and also effectively absorb the noise that the first balancing component 5131 may generate during vibration compensation. Furthermore, the first balancing component 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.

[0242] 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 thrown 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.

[0243] During the operation of the garment processing device 100, the absorbent element absorbs a large amount of water. When the output shaft 511 rotates at high speed, the water inside the absorbent element is flung out due to centrifugal force. The water collection tank prevents this water from flowing or accumulating freely inside the device. The water collection tank can collect the water flung out by the absorbent element in a timely manner, preventing water from accumulating on other components inside the device, thereby reducing problems such as rust and corrosion caused by moisture.

[0244] For clothing processing devices 100 containing electrical components, such as compressor 6 and fan motor in 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.

[0245] Furthermore, if the absorbent absorbs too much moisture and cannot drain it promptly, its absorption capacity will decrease. The collection tank collects the dissipated moisture in a timely manner, allowing the absorbent to maintain good absorption performance, ensuring effective absorption of both moisture and noise. Prolonged exposure to moisture can negatively impact the absorbent's material properties and structural integrity. By promptly draining moisture through the collection tank, the absorbent can operate in a relatively dry state, reducing material aging and deformation caused by prolonged dampness, thus extending its service life.

[0246] In some embodiments, combined with Figure 15, Figure 15 The schematic view of the compressor 6, the second fan 5134 and the motor position disclosed in the embodiments of the present application, the clothes treatment apparatus 100 further comprises a compressor 6, the compressor 6 is arranged at one side of the second motor 51.

[0247] The compressor 6 compresses the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas, and the high-temperature and high-pressure refrigerant gas enters the condenser. In the condenser, the refrigerant gas releases heat, which is used to heat air. The heated drying gas is sent into the drum 2 of the clothes treatment apparatus 100, contacts with the wet clothes, and evaporates the water in the clothes into water vapor. The air containing water vapor is guided to the evaporator. The refrigerant in the evaporator absorbs the heat in the air, so that the water vapor is condensed into liquid water, thereby achieving dehumidification. The dehumidified air is sent into the compressor 6 again to start a new cycle until the clothes are dried.

[0248] In some embodiments, the fan comprises a first fan, the first fan is arranged corresponding to the air duct assembly 3, the first motor drives the first fan to rotate, and the first fan is used to send the drying gas into the air duct assembly 3 and make the drying gas pass through the air duct assembly 3 into the drying cavity.

[0249] In some embodiments, the clothes treatment apparatus 100 further comprises a second fan 5134, the second fan 5134 is arranged on the output shaft 511 and opposite to the compressor 6. When the output shaft 511 of the second motor 51 rotates, the second fan 5134 can be driven to rotate to deliver cooling air to the compressor 6.

[0250] In the working process of the compressor 6, a large amount of heat is generated. The refrigeration fan originally arranged on the side of the compressor 6 away from the second motor 51 is used to cool the compressor 6. In the embodiments, the refrigeration fan is cancelled, the compressor 6 is moved outwardly away from the second motor 51, and a fan is added at the shaft end of the output shaft 511 to cool the compressor 6. In this way, the cooling of the compressor 6 is ensured, and the vibration of the output shaft 511 is compensated.

[0251] In some embodiments, in combination Figure 16 , Figure 16 The structural schematic view of the second fan 5134 disclosed in the embodiments of the present application, the second fan 5134 comprises an inner ring fan 51341, the inner ring fan 51341 is an axial flow fan, and the inner ring fan 51341 is connected to the output shaft 511. When the output shaft 511 rotates, the inner ring fan 51341 can rotate with it.

[0252] In some embodiments, the second fan 5134 further comprises an outer ring fan 51342, which is an axial fan, connected to the outer periphery of the inner ring fan 51341, and the inner ring fan 51341 is opposite to the air outlet direction of the outer ring fan 51342, so that the output shaft 511 can drive the second fan 5134 to deliver cooling air to the compressor 6 in both forward rotation and reverse rotation.

[0253] When the output shaft 511 is in one of the forward rotation state or the reverse rotation state, the inner ring fan 51341 delivers cooling air to the compressor 6, and the outer ring fan 51342 delivers cooling air to the second motor 51; when the output shaft 511 is in the other of the forward rotation state or the reverse rotation state, the outer ring fan 51342 delivers cooling air to the compressor 6, and the inner ring fan 51341 delivers cooling air to the second motor 51. Therefore, no matter whether the output shaft 511 is in the forward rotation state or the reverse rotation state, one of the inner ring fan 51341 and the outer ring fan 51342 can deliver cooling air to the compressor 6, and the other can deliver cooling air to the second motor 51.

[0254] Among them, the working principle of the axial fan is to generate airflow through the rotation of the impeller, which is usually composed of multiple blades. When the second motor 51 starts, the output shaft 511 drives the impeller to start rotating, causing air flow. The blades suck air from one side of the impeller, and then discharge it to the other side through the hollow part in the center of the shaft. When the air is sucked in, it passes through the blades and is compressed, and then the air is pushed to the end of the blades to form a high-speed airflow, which is ejected through the end of the blades and then pushed along the axis direction of the impeller.

[0255] During the operation of the clothes treatment device 100, the output shaft 511 may be rotated in the forward direction or the reverse direction due to different working modes or fault handling, etc. No matter the rotation direction of the output shaft 511, the supply of cooling air to the compressor 6 can be ensured, so that the compressor 6 can continuously work in the appropriate temperature range, improve the reliability and service life of the compressor 6, and make the whole device run more stably. In addition, under the premise of always being able to deliver cooling air to the compressor 6, cooling air can also be delivered to the second motor 51 at all times, further ensuring the normal operation of the second motor 51.

[0256] In some embodiments, in combination with Figure 16 , the second fan 5134 further comprises a first connecting ring 51342a, which is arranged around the outer periphery of the inner ring fan 51341, and the inner surface of the first connecting ring 51342a is connected with the inner ring fan 51341, and the outer ring fan 51342 is connected to the outer surface of the first connecting ring 51342a.

[0257] The first connecting ring 51342a enhances the stability of the connection between the inner fan 51341 and the outer fan 51342. During the rotation of the fan, especially at high speed, the stable connection structure can reduce the shaking and deformation of the fan blades, thereby improving the overall stability and reliability of the fan.

[0258] In some embodiments, in combination with Figure 16 , the second fan 5134 further comprises a second connecting ring 51342b, the second connecting ring 51342b is arranged around the outer periphery of the outer fan 51342, and the second connecting ring 51342b is connected with the outer fan 51342.

[0259] The second connecting ring 51342b further enhances the structural strength of the outer fan 51342. During the rotation of the fan, especially when facing different working conditions and load changes, the second connecting ring 51342b can provide additional support force to reduce the risk of deformation and damage of the fan blades.

[0260] In some embodiments, in combination with Figure 16 , the inner fan 51341 comprises a plurality of first fan blades (not shown in the figure), and the edge of the first fan blades for connecting with the first connecting ring 51342a is a first edge 51341a.

[0261] In some embodiments, the outer fan 51342 comprises a plurality of second fan blades (not shown in the figure), and the edge of the second fan blades for connecting with the second connecting ring 51342b is a second edge 51342c. The first edge 51341a and the second edge 51342c are both helical lines, and the rotation directions of the first edge 51341a and the second edge 51342c are opposite.

[0262] In this way, the rotation directions of the first edge 51341a and the second edge 51342c are opposite, so that when the output shaft 511 rotates, the air outlet directions of the inner fan 51341 and the outer fan 51342 are opposite. The second fan 5134 can deliver cooling air to the compressor 6 and the motor body when the output shaft 511 rotates in any direction, which can increase the service life of the compressor and the second motor and improve the cooperative working efficiency of the entire device.

[0263] In some embodiments, in combination with Figure 4 , Figure 15 and Figure 16 , the second motor 51 comprises a motor shell 512, the first end 511a of the output shaft 511 extends out of the motor shell 512 towards the side wall of the compressor 6, the first end 511a of the output shaft 511 is in driving connection with the drum 2, and the second fan 5134 is arranged at the first end 511a of the output shaft 511.

[0264] The layout enhances the integration between components, since the second fan 5134 is arranged close to the compressor 6 and shares the same shaft end with the belt pulley 22, so that the power is transmitted from the output shaft 511 to the drum 2, and the second fan 5134 is conveniently driven to rotate, thereby providing cooling air for the compressor 6, and improving the cooperative working efficiency of the whole device. In the limited space, the reasonable layout reduces the overall volume of the device, and saves the space resources.
