[0002] This application claims priority to Chinese Patent Application No. 2025204219454, filed on March 11, 2025, entitled "Multi-tub Washing Machine", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of clothing processing technology, and in particular to a multi-tube clothing processing device and a combined clothing processing equipment. Background Technology

[0004] With economic development and improved living standards, washing machines have become increasingly common, and people have higher and higher requirements for their performance. Especially with increased hygiene awareness, while meeting the washing needs of ordinary clothes, more and more users need to wash inner and outer garments, children's clothes, etc., separately, or wash small amounts of clothing promptly. Ordinary washing machines, due to their single capacity, cannot meet these needs for separate washing and care. Therefore, twin-tub and multi-tub washing machines have emerged, enabling separate washing of clothes in different sections.

[0005] Currently, most multi-drum laundry detergent units on the market have a large-capacity drum and several smaller drums. To facilitate the loading and unloading of clothes from the smaller drums, the loading openings of these smaller drums must have a certain diameter; that is, the diameter of the loading opening cannot be too small. This can cause clothes to easily move outside the smaller drums during washing, resulting in fabric entanglement. Furthermore, because multi-drum laundry detergent units have multiple independent drums, they generate greater vibrations during washing, which can easily cause collisions between the outer drum and the casing, as well as operating noise, thus affecting their operational safety. Utility Model Content

[0006] This application discloses a multi-tube garment processing device and a combined garment processing equipment, which can solve the problem of fabric jamming while providing better shock absorption and reducing vibration and noise during the operation of the multi-tube garment processing device.

[0007] To achieve the above objectives, in a first aspect, this application discloses a multi-tube garment processing device, the multi-tube garment processing device comprising:

[0008] The box has a front-to-back direction, a left-to-right direction and a top-to-bottom direction, and the box has at least two loading and unloading ports on the front side in the front-to-back direction;

[0009] At least two doors, each of which is rotatably connected to the housing to open or close one of the loading / unloading ports;

[0010] At least two cylindrical assemblies are disposed inside the housing, each cylindrical assembly is provided with a cylindrical opening, and each cylindrical opening is oriented toward a loading / unloading port;

[0011] At least two damping assemblies, each comprising two shock absorbers, one end of which is connected to the bottom of the housing, and the other end of which is connected to the outer peripheral side of the cylindrical assembly; the two shock absorbers of at least one damping assembly are respectively located on opposite sides of the cylindrical assembly in the left-right direction; and,

[0012] At least four suspension spring assemblies, one end of which is connected to the top of the housing and the other end of which is connected to the outer peripheral side of the cylinder assembly, and at least two of the suspension spring assemblies are respectively located on both sides of a cylinder assembly in the left-right direction;

[0013] Wherein, the at least two cylindrical assemblies are arranged side by side along the left-right direction, and in the direction from the front side of the box to the rear side of the box, the cylindrical assemblies are inclined from top to bottom;

[0014] The suspension spring assembly is inclined relative to the front-to-back direction, and the shock absorber is inclined relative to the up-down direction from front to back in the direction from the bottom of the housing to the top of the housing.

[0015] The multi-drum laundry handling device provided in this application has at least two independent drum assemblies with separate laundry handling chambers, enabling the sorting and washing of clothes to meet individual needs. Furthermore, this application positions the drum assemblies at an angle from top to bottom in the direction from the front to the rear of the unit, allowing the drum opening to be higher than the bottom of the drum assembly near the rear of the unit. This design encourages the clothes inside the drum assemblies to move towards the bottom of the assembly during operation, preventing them from moving towards the opening and getting caught in the fabric. This reduces the likelihood of damage to clothes and improves the user's laundry experience.

[0016] Meanwhile, because the excitation force (i.e., centrifugal force) of the tilted cylinder assembly is decomposed into components in the front-to-back direction and the vertical direction, the excitation force in the front-to-back direction becomes larger, leading to particularly noticeable and severe vibration. Therefore, this application also tilts the suspension spring assembly relative to the front-to-back direction, and tilts the shock absorber from front to back in the direction from the bottom to the top of the housing. In this way, the force exerted by the suspension spring assembly on the tilted cylinder assembly can have an additional component in the front-to-back direction, and the force exerted by the shock absorber on the tilted cylinder assembly can also have an additional component in the front-to-back direction, thus offsetting the front-to-back component of the excitation force of the tilted cylinder assembly. This solves the problem of large excitation force in the front-to-back direction caused by the tilted cylinder assembly, thereby achieving a better shock absorption effect and reducing vibration and noise during the operation of the multi-cylinder garment processing device. In other words, through the reasonable use of the tilted suspension spring assembly and the tilted shock absorber, their mutual cooperation allows for better control of the vibration of the tilted cylinder assembly in the front-to-back direction, effectively reducing the vibration generated during the operation of the entire machine, reducing the probability of collision and operating noise between the cylinder assembly and the housing, and improving the performance and reliability of the product.

[0017] As an optional implementation, in an embodiment of the first aspect of this application, the projection of the axis of the shock absorber in the left-right direction is configured as a first projection line, the projection of the axis of the cylinder assembly in the left-right direction is configured as a second projection line, and the angle between the first projection line and the second projection line is configured as α, where 85° < α < 95°.

[0018] This configuration allows the axis of the shock absorber and the axis of the cylinder assembly to be approximately 90° apart. This not only ensures that the shock absorber can stably support the cylinder assembly, but also ensures that the force exerted by the shock absorber on the tilted cylinder assembly can be decomposed into components in the front-to-back direction and the vertical direction. The front-to-back component of the shock absorber's force on the tilted cylinder assembly can be used to counteract the front-to-back component of the excitation force of the tilted cylinder assembly, thus solving the problem of large front-to-back excitation force caused by the tilted cylinder assembly. This results in better shock absorption and reduces vibration and noise during the operation of the multi-cylinder garment handling device.

[0019] As an optional implementation, in an embodiment of the first aspect of this application, the suspension spring assembly includes:

[0020] A first suspension spring, one end of which is connected to the top of the housing, and the other end of which is connected to the outer peripheral side of the cylinder assembly; and

[0021] The second suspension spring has one end connected to the top of the housing and the other end connected to the outer peripheral side of the cylinder assembly. The second suspension spring and the first suspension spring are located on the same side of the cylinder assembly in the left-right direction, and the second suspension spring and the first suspension spring are arranged along the front-back direction.

[0022] In the direction from the bottom of the housing to the top of the housing, one of the first suspension spring and the second suspension spring is inclined from back to front, and the other of the first suspension spring and the second suspension spring is inclined from front to back.

[0023] Understandably, when the multi-tube garment processing device is working, if the excitation force of the tilting tube assembly has a forward component in the front-to-back direction, the tube assembly tends to move forward. This stretches the suspension springs that are tilted from front to back, allowing the suspension springs to exert a backward component of the force on the tilting tube assembly, thus counteracting the forward component of the excitation force of the tube assembly. Conversely, if the excitation force of the tilting tube assembly has a backward component in the front-to-back direction, the tube assembly tends to move backward, stretching the suspension springs that are tilted from back to front. This stretches the suspension springs to exert a forward component of the force on the tilting tube assembly, thus counteracting the backward component of the excitation force of the tilting tube assembly. Therefore, whether the excitation force of the tilting tube assembly has a forward or backward component in the front-to-back direction, the suspension spring assembly can provide shock absorption, improving the shock absorption effect of the suspension spring assembly.

[0024] As an optional implementation, in an embodiment of the first aspect of this application, in the front-rear direction, the first suspension spring is closer to the front side of the housing than the second suspension spring, and in the direction from the bottom of the housing to the top of the housing, the first suspension spring is inclined from back to front, and the second suspension spring is inclined from front to back.

[0025] This configuration allows the connection points between the first suspension spring and the cylinder assembly, and the connection points between the second suspension spring and the cylinder assembly, to be concentrated in the middle of the cylinder assembly. This makes the connection points between the first suspension spring and the cylinder assembly, and the connection points between the second suspension spring and the cylinder assembly, relatively close to the center of mass of the cylinder assembly. This reduces or avoids the rotational torque generated by the cylinder assembly due to the forces of the first and second suspension springs, thereby reducing the probability of the cylinder assembly rotating, improving the fixed stability of the cylinder assembly, and reducing the generation of vibration and noise.

[0026] As an optional implementation, in the embodiment of the first aspect of this application, the axes of the first suspension spring and the second suspension spring intersect at a first point. On a projection plane perpendicular to the left and right directions, the line segment connecting the first point and the center of mass of the cylinder assembly is a first connecting line, which is parallel to the up and down directions.

[0027] This configuration ensures that the point of application of the combined force of the first and second suspension springs on the cylinder assembly is zero or approximately zero in the front-to-back direction from the center of mass of the cylinder assembly. This effectively prevents the cylinder assembly from generating rotational torque due to the forces of the first and second suspension springs, thus maintaining a balanced state and preventing the cylinder assembly from tilting or moving. This avoids unnecessary vibration or displacement during start-up or shutdown, resulting in better shock absorption and reducing vibration and noise during the operation of the multi-cylinder garment processing device.

[0028] As an optional implementation, in an embodiment of the first aspect of this application, the axes of the first suspension spring and the second suspension spring intersect at a first point, and the first suspension spring and the second suspension spring are symmetrically arranged about a first straight line, the first straight line passing through the first point, and on a projection plane perpendicular to the left and right directions, the first straight line and the axis of the cylinder assembly are arranged perpendicularly.

[0029] Because of the tilted design of the drum assembly, the clothes are concentrated at the rear end of the drum assembly during the operation of the multi-drum garment handling device, resulting in greater vibration at the rear end. By decomposing the resultant force of the first and second suspension springs on the drum assembly in the front-to-back direction, a rearward component force is generated. This allows the suspension spring assembly to effectively dampen the vibration at the rear end of the drum assembly, thus better controlling the vibration of the tilted drum assembly at the rear end. This effectively reduces the vibration generated during the operation of the entire machine, lowers the probability of collisions between the drum assembly and the housing and the operating noise, and improves the performance and reliability of the product.

[0030] As an optional implementation, in the embodiment of the first aspect of this application, the included angle between the first suspension spring and the first straight line is defined as γ1, and the included angle between the second suspension spring and the first straight line is defined as γ2, 15°≤γ1≤45°, γ2=γ1.

[0031] When the above relationship is satisfied, the vertical component forces of the first and second suspension springs are both greater than their horizontal component forces. This ensures that the vertical component forces of the first and second suspension springs are sufficiently large to maintain the stability of the cylinder assembly in the vertical direction, while also preventing the horizontal component forces of the first and second suspension springs from being too small. This effectively counteracts the horizontal component force of the inclined cylinder assembly's excitation force, solving the problem of large horizontal excitation forces caused by the inclined cylinder assembly. This facilitates the cylinder assembly to reach a balanced state, preventing it from tilting or moving, thus avoiding unnecessary vibration or displacement during start-up or shutdown. This results in better shock absorption and reduces vibration and noise during the operation of the multi-cylinder garment processing device.

[0032] As an optional implementation, in an embodiment of the first aspect of this application, on a projection plane perpendicular to the front-back direction, the angle between the axis of the suspension spring assembly and the up-down direction is defined as β, where 5°≤β≤20°.

[0033] When the above relationship is satisfied, the component force of the suspension spring assembly in the vertical direction can be large enough to maintain the stability of the cylinder assembly in the vertical direction, while the component force of the suspension spring assembly in the horizontal direction can be kept small enough to maintain the stability of the cylinder assembly in the horizontal direction. This facilitates the cylinder assembly to reach a balanced state, prevents the cylinder assembly from tilting or moving, and avoids unnecessary vibration or displacement during start-up or shutdown. This can achieve a better shock absorption effect and reduce vibration and noise during the operation of the multi-cylinder clothing processing device.

[0034] As an optional implementation, in an embodiment of the first aspect of this application, the tilt angle between the axis of the cylindrical assembly and the front-rear direction is 2°-6°.

[0035] When the above relationship is satisfied, it can not only ensure that the inner wall of the drum assembly can effectively guide the clothes put in from the drum opening to the bottom of the drum assembly, avoiding accumulation at the drum opening and facilitating the loading of clothes; it can also make the clothes inside the drum assembly tend to move towards the bottom of the drum assembly when the multi-drum laundry handling device is running, preventing the clothes inside the drum assembly from moving towards the drum opening and causing cloth to get caught, thereby reducing the chance of damaging the clothes and improving the user's laundry experience; it can also prevent the drum assembly from tilting excessively, so that the drum assembly can operate smoothly and reduce vibration noise.

[0036] Secondly, this application discloses a combined garment processing device, the combined garment processing device comprising:

[0037] First garment processing device;

[0038] The second garment processing device is a multi-tube garment processing device as described in the first aspect above, and the second garment processing device is detachably mounted on the top of the first garment processing device.

[0039] Compared with the prior art, the beneficial effects of this application are as follows:

[0040] The multi-drum laundry handling device provided in this application embodiment has at least two drum assemblies with independent laundry handling chambers, enabling the sorting and washing of clothes to meet individual needs. Furthermore, this application also arranges the drum assemblies at an angle from top to bottom in the direction from the front to the rear of the cabinet, so that the loading opening of the drum assembly is higher than the bottom of the drum assembly near the rear of the cabinet. This allows the clothes inside the drum assembly to tend to move towards the bottom of the drum assembly during operation, preventing clothes from moving towards the loading opening and getting caught, thus reducing the likelihood of damage to clothes and improving the user's laundry experience.

[0041] Meanwhile, because the excitation force (i.e., centrifugal force) of the tilted cylinder assembly is decomposed into components in the front-to-back direction and the vertical direction, the excitation force in the front-to-back direction becomes larger, leading to particularly noticeable and severe vibration. Therefore, this application also tilts the suspension spring assembly relative to the front-to-back direction, and tilts the shock absorber from front to back in the direction from the bottom to the top of the housing. In this way, the force exerted by the suspension spring assembly on the tilted cylinder assembly can have an additional component in the front-to-back direction, and the force exerted by the shock absorber on the tilted cylinder assembly can also have an additional component in the front-to-back direction, thus offsetting the front-to-back component of the excitation force of the tilted cylinder assembly. This solves the problem of large excitation force in the front-to-back direction caused by the tilted cylinder assembly, thereby achieving a better shock absorption effect and reducing vibration and noise during the operation of the multi-cylinder garment processing device. In other words, through the reasonable use of the tilted suspension spring assembly and the tilted shock absorber, their mutual cooperation allows for better control of the vibration of the tilted cylinder assembly in the front-to-back direction, effectively reducing the vibration generated during the operation of the entire machine, reducing the probability of collision and operating noise between the cylinder assembly and the housing, and improving the performance and reliability of the product.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0067] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

[0070] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The technological development trends for these products primarily focus on intelligentization, energy conservation and environmental protection, optimized user experience, and the application of new materials. Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.

[0071] As an essential household appliance widely used in people's lives, washing machines have greatly reduced people's housework burden. Generally, a family only has one washing machine. However, with the improvement of people's quality of life, sorting and washing clothes has become a lifestyle trend and pursuit. More and more users are sorting their clothes for washing, such as washing inner and outer garments separately, washing baby and adult clothes separately, washing clothes with different levels of soiling separately, and washing clothes of different colors separately.

[0072] In response, users usually increase the number of washing machines, but multiple washing machines are costly, take up a lot of space, and have high maintenance costs. Therefore, multi-drum clothing handling devices with twin or more drums have emerged to realize the washing of clothes in separate drums.

[0073] Multi-drum laundry handling devices in related technologies typically include a large-capacity drum and several smaller drums. To facilitate the user's loading and unloading of clothes from the smaller drums, the loading opening of the smaller drums must have a certain diameter; that is, the diameter of the loading opening cannot be too small. Otherwise, during washing, the clothes may easily move outside the loading opening of the smaller drums, resulting in fabric entanglement.

[0074] Specifically, to ensure the structural strength of the front end of the small drum, a front end piece is usually installed at the opening of the small drum. However, to facilitate users in taking clothes out of the small drum, the loading port of the front end piece must have a certain diameter, that is, the diameter of the loading port of the front end piece cannot be too small, usually not less than 160mm. In addition, the diameter of the small drum is limited by the width of the box and vibration, so the diameter of the small drum can only be about 220mm. This results in a relatively small radial width of the front end piece of the small drum. For example, the width of the front end piece is usually only about (220-160)mm / 2=30mm. As a result, the front end piece is not enough to prevent the clothes in the drum from moving forward, which makes it easy for the clothes to be caught in the gap between the front end piece and the door seal, resulting in the problem of fabric being caught.

[0075] Furthermore, multi-drum laundry handling units, due to their multiple independent drums, experience greater vibrations during washing, which can easily cause collisions between the outer drum and the casing, as well as operating noise, thus affecting their operational safety.

[0076] In view of this, the embodiments of this application provide a multi-tube garment processing device that can effectively solve the problem of fabric jamming while achieving better shock absorption.

[0077] Specifically, the multi-tube garment processing device provided in this application includes a box body, at least two doors, and at least two tube assemblies. The box body has at least two loading / unloading ports on its front side in the front-rear direction. Each door is rotatably connected to the box body to open or close a loading / unloading port. At least two tube assemblies are disposed inside the box body, and each tube assembly has a tube opening, with each tube opening facing a loading / unloading port. The at least two tube assemblies are arranged side by side in the left-right direction. In the direction from the front side of the box body to the rear side of the box body, the tube assemblies are inclined from top to bottom.

[0078] Because the multi-drum laundry handling device provided in this application has at least two drum assemblies with independent laundry handling chambers, it can achieve the purpose of sorting and washing clothes, meeting people's personalized requirements. At the same time, this application also arranges the drum assemblies at an angle from top to bottom in the direction from the front side to the rear side of the cabinet, so that the drum opening of the drum assembly can be higher than the bottom of the drum assembly near the rear side of the cabinet. Therefore, when the multi-drum laundry handling device is running, the clothes inside the drum assembly tend to move towards the bottom of the drum assembly, thereby preventing the clothes from moving towards the drum opening and causing the clothes to get caught, thus reducing the probability of damage to the clothes and improving the user's laundry experience.

[0079] In some embodiments, the multi-tube garment processing device provided in this application further includes a shock absorber and a suspension spring assembly. One end of the shock absorber is connected to the bottom of the housing, and the other end is connected to the outer peripheral side of the tube assembly. The shock absorber is located on the side of the tube assembly in the left-right direction. One end of the suspension spring assembly is connected to the top of the housing, and the other end is connected to the outer peripheral side of the tube assembly. The suspension spring assembly is located on the side of the tube assembly in the left-right direction. The suspension spring assembly is inclined relative to the front-back direction, and the shock absorber is inclined from front to back in the direction from the bottom of the housing to the top of the housing.

[0080] Because the excitation force (i.e., centrifugal force) of the tilted cylinder assembly is decomposed into components in the front-to-back direction and components in the up-to-down direction, the excitation force in the front-to-back direction becomes larger, resulting in particularly noticeable and severe vibration. Therefore, this application also tilts the suspension spring assembly relative to the front-to-back direction, and tilts the shock absorber from front to back in the direction from the bottom to the top of the housing. In this way, the force exerted by the suspension spring assembly on the tilted cylinder assembly can have an additional component in the front-to-back direction, and the force exerted by the shock absorber on the tilted cylinder assembly can also have an additional component in the front-to-back direction, so as to offset the component of the excitation force of the tilted cylinder assembly in the front-to-back direction, thereby solving the problem of large excitation force in the front-to-back direction caused by the tilted cylinder assembly, thus achieving a better shock absorption effect and reducing vibration and noise during the operation of the multi-cylinder clothing processing device.

[0081] In other words, through the proper use of the inclined suspension spring assembly and the inclined shock absorber, the two work together to better control the vibration of the inclined cylinder assembly in the front-to-back direction, effectively reducing the vibration generated during the operation of the whole machine and improving the performance and reliability of the product.

[0082] In some embodiments, the multi-tube garment processing device provided in this application further includes at least two door seals, each door seal being disposed between a tube opening and a take-out / put-out port, and each door seal being used to seal the gap between a tube opening and a take-out / put-out port.

[0083] That is, the front end of the door seal is connected to the front side of the cabinet, and the rear end of the door seal is connected to the front face of the drum assembly. The door seal at least serves to seal the gap between the front face of the drum assembly and the front side of the cabinet, preventing washing water from flowing forward from the drum opening and into the gap between the front face of the drum assembly and the front side of the cabinet.

[0084] In some embodiments, the tilt angle between the axis of the cylinder assembly and the front-to-back direction is 2°-6°.

[0085] When the above relationship is satisfied, it can not only ensure that the inner wall of the drum assembly can effectively guide the clothes put in from the drum opening to the bottom of the drum assembly, avoiding accumulation at the drum opening and facilitating the loading of clothes; it can also make the clothes in the drum assembly tend to move towards the bottom of the drum assembly when the multi-drum laundry handling device is running, preventing the clothes inside the drum assembly from moving towards the drum opening and causing cloth to get caught, thereby reducing the chance of damaging the clothes and improving the user's laundry experience; it can also prevent the drum assembly from tilting excessively, so that the drum assembly can operate smoothly and reduce vibration noise.

[0086] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0087] Please see Figure 1 and Figure 2 , Figure 1 and Figure 2 All figures are external views of the multi-tube clothing processing device. This application provides a multi-tube clothing processing device 100, which includes a housing 11. The housing 11 forms the external appearance of the multi-tube clothing processing device 100, and the interior of the housing 11 has a receiving space (not shown). This receiving space is used to house and fix various components within the multi-tube clothing processing device 100 to ensure the structural stability of the multi-tube clothing processing device 100. The housing 11 also needs to be aesthetically pleasing so that the multi-tube clothing processing device 100 placed indoors improves the user's daily life experience.

[0088] like Figure 1 As shown, the box has a front-to-back direction, a left-to-right direction, and a top-to-bottom direction. Specifically, the box 11 has a front side and a rear side, which are opposite sides in the front-to-back direction; the box 11 has a left side and a right side, which are opposite sides in the left-to-right direction; the box 11 has a top and a bottom, which are opposite ends in the top-to-bottom direction.

[0089] The enclosure 11 can be installed on the indoor floor or in the space below the room, and the front of the enclosure 11 is usually facing the user, while the rear of the enclosure 11 is usually facing the wall.

[0090] like Figure 2 and Figure 3 As shown, Figure 3 This is an internal structural diagram of a multi-tube garment handling device. The housing 11 has a front plate 11a located at the front, a rear plate 11b located at the rear of the housing 11, a pair of side plates 11c located on the left and right sides of the housing 11, a top plate 11d located at the top of the housing 11, and a bottom plate 11e located at the bottom of the housing 11. The front plate 11a, rear plate 11b, top plate 11d, bottom plate 11e, and side plates 11c enclose a receiving space.

[0091] The front panel 11a and the rear panel 11b are the two ends of the housing 11 that are arranged opposite each other in the front-to-back direction, and the side where the front panel 11a is located is the side of the multi-tube clothing handling device 100 facing the user. The top panel 11d and the bottom panel 11e are the two ends of the housing 11 that are arranged opposite each other in the vertical direction (i.e., the up-down direction), and the two side panels 11c are the two ends of the housing 11 that are arranged opposite each other in the left-to-right direction.

[0092] In some embodiments, the housing 11 has at least two access ports on its front side in the front-rear direction, such as two access ports, three access ports, four access ports, etc. The at least two access ports can be arranged side by side in the vertical direction or side by side in the horizontal direction.

[0093] The following will provide a more detailed explanation of the technical solution of this application, taking the example of two loading and unloading ports on the front side of the box 11 in the front-rear direction.

[0094] like Figure 2 As shown, the box body 11 has two loading and unloading ports on the front side in the front-rear direction. That is, the front panel 11a has two loading and unloading ports, namely the first loading and unloading port 111 and the second loading and unloading port 112. The first loading and unloading port 111 and the second loading and unloading port 112 are arranged side by side in the left-right direction. The first loading and unloading port 111 and the second loading and unloading port 112 are respectively connected to the accommodating space. Both the first loading and unloading port 111 and the second loading and unloading port 112 are used for loading and unloading clothes.

[0095] In some embodiments, the box body 11 includes a main body 11f and at least three crossbeams 11g, wherein the first loading port 111 and the second loading port 112 are both located on the front side of the main body 11f in the front-rear direction, and the at least three crossbeams 11g are respectively connected to the main body 11f, and the at least three crossbeams 11g are arranged in the left-right direction.

[0096] Specifically, the main body 11f of the container can be composed of the aforementioned front plate 11a, rear plate 11b, top plate 11d, bottom plate 11e, and side plates 11c, with each crossbeam 11g connecting the front plate 11a and the rear plate 11b. Thus, at least three crossbeams 11g can be used to enhance the structural strength of the main body 11f of the container.

[0097] Please continue to refer to section 2 and... Figure 3 The multi-tube clothing handling device 100 provided in this application embodiment also includes a first door 12a and a second door 12b. The first door 12a is rotatably connected to the housing 11 to open or close the first take-out port 111, and the second door 12b is rotatably connected to the housing 11 to open or close the second take-out port 112.

[0098] When the multi-drum laundry handling device is not in use, the first door 12a closes the first loading / unloading port 111, and the second door 12b closes the second loading / unloading port 112 to prevent external dust and clothes from entering the cabinet 11. When laundry is needed, the first door 12a opens the first loading / unloading port 111 to put clothes into the cabinet 11, and the second door 12b opens the second loading / unloading port 112 to put clothes into the cabinet 11.

[0099] When the multi-drum laundry handling device 100 is washing clothes, the first door 12a closes the first loading and unloading port 111 to prevent clothes from being thrown out of the cabinet 11, and the second door 12b closes the second loading and unloading port 112 to prevent clothes from being thrown out of the cabinet 11, ensuring the smooth progress of the washing process; when the washing is completed, the first door 12a opens the first loading and unloading port 111 to make it easier to take out the clothes, and the second door 12b opens the second loading and unloading port 112 to make it easier to take out the clothes.

[0100] In some embodiments, the multi-tube garment processing device 100 provided in this application further includes two tube assemblies 13a, which are disposed in the housing 11. Each tube assembly 13a is provided with a tube opening 13b, and each tube opening 13b is disposed facing a take-out port.

[0101] In some embodiments, each tube assembly may include an outer tube and a roller. The outer tube is disposed within the housing 11, that is, the outer tube is disposed within the receiving space of the housing 11, and the front end of the outer tube is provided with an outer tube opening facing the loading / unloading port. The roller is rotatably disposed within the outer tube, and the interior of the roller defines a clothing processing chamber for receiving clothing. The roller is provided with a clothing loading port communicating with the clothing processing chamber, and the clothing loading port is disposed facing the outer tube opening. The tube assembly opening includes an outer tube opening and a clothing loading port.

[0102] In other words, such as Figure 4 and Figure 5 As shown, the multi-tube garment handling device 100 provided in this application embodiment includes two outer tubes 13 and two rollers. Each roller may include a tube body and a front end member. The interior of the tube body defines a garment handling cavity for accommodating garments, and the tube body has an opening communicating with the garment handling cavity. The front end member is located at the opening of the tube body and has a garment inlet facing the loading / unloading port. This allows the front end member to enhance the structural strength of the tube body and the rollers, and also, to a certain extent, prevents garments from escaping from the garment handling cavity.

[0103] Optionally, the front end of the cylinder can be a ring structure, and its material can be a metal material, such as stainless steel, aluminum alloy, etc.

[0104] In this application, both outer cylinders 13 are disposed inside the housing 11, that is, the two outer cylinders 13 are disposed in the housing space of the housing 11, and one end of one outer cylinder 13 is provided with a first outer cylinder opening 131 facing the first take-out port 111, and one end of the other outer cylinder 13 is provided with a second outer cylinder opening 132 facing the second take-out port 112. That is, the first outer cylinder opening 131 is opened facing the first take-out port 111, and the second outer cylinder opening 132 is opened facing the second take-out port 112.

[0105] The outer cylinder 13 can be a cylindrical structure, generally made of plastic, and is generally constructed as a bucket for holding washing water. That is, the internal space of the outer cylinder 13 can be used to hold washing liquids such as water, detergent, fabric softener, etc.

[0106] In some embodiments, the multi-tub garment handling device 100 provided in this application further includes a first door seal 14a. The first door seal 14a is disposed at the first outer tub opening 131 of the outer tub 13 and extends to the first loading / unloading port 111. The first door seal 14a is used to seal the gap between the first outer tub opening 131 and the first loading / unloading port 111. That is, the front end of the first door seal 14a is connected to the front plate 11a, and the rear end of the first door seal 14a is connected to the front end face of the outer tub 13. Thus, the first door seal 14a at least seals the gap between the front end face of the outer tub 13 and the front plate 11a of the casing, preventing washing water from flowing forward from the first outer tub opening 131 into the gap between the front end face of the outer tub 13 and the front plate 11a.

[0107] Specifically, the first door seal 14a is an annular structure, arranged around the first access port 111 and the first outer cylinder opening 131, and positioned between the first access port 111 and the first outer cylinder opening 131 to seal the gap between them. When the first door 12a closes the first access port 111, the first door seal 14a prevents water from the outer cylinder 13 from entering the tank 11, and simultaneously prevents water from the outer cylinder 13 from overflowing from the first access port 111 of the tank 11.

[0108] Optionally, the first door seal 14a is made of an elastic sealing material, such as rubber, plastic, silicone, etc. The peripheral edge of the front end of the first door seal 14a is sealed to the peripheral edge of the first access port 111, and the peripheral edge of the rear end of the first door seal 14a is sealed to the peripheral edge of the first outer cylinder opening 131, thereby sealing the gap between the first access port 111 of the box body 11 and the first outer cylinder opening 131 of the outer cylinder 13. Therefore, when the first door 12a closes the first access port 111 on the front side of the box body 11, the first door seal 14a can prevent water in the outer cylinder 13 from entering the box body 11, and at the same time, the first door 12a can prevent water in the outer cylinder 13 from overflowing from the first access port 111 of the box body 11.

[0109] In some embodiments, the multi-tub garment handling device 100 provided in this application further includes a second door seal 14b. The second door seal 14b is disposed at the second outer tub opening 132 of the outer tub 13 and extends to the second loading / unloading port 112. The second door seal 14b is used to seal the gap between the second outer tub opening 132 and the second loading / unloading port 112. That is, the front end of the second door seal 14b is connected to the front plate 11a, and the rear end of the second door seal 14b is connected to the front end face of the outer tub 13. Thus, the second door seal 14b at least seals the gap between the front end face of the outer tub 13 and the front plate 11a of the casing, preventing washing water from flowing forward from the second outer tub opening 132 into the gap between the front end face of the outer tub 13 and the front plate 11a.

[0110] Specifically, the second door seal 14b has a ring structure and is arranged around the second access port 112 and the second outer cylinder opening 132. The second door seal 14b is positioned between the second access port 112 and the second outer cylinder opening 132 to seal the gap between them. When the second door 12b closes the second access port 112, the second door seal 14b prevents water from the outer cylinder 13 from entering the tank 11, and simultaneously prevents water from the outer cylinder 13 from overflowing from the second access port 112 of the tank 11.

[0111] Optionally, the second door seal 14b is made of an elastic sealing material, such as rubber, plastic, silicone, etc. The front peripheral edge of the second door seal 14b is sealed to the peripheral edge of the second access port 112, and the rear peripheral edge of the second door seal 14b is sealed to the peripheral edge of the second outer cylinder opening 132, thereby sealing the gap between the second access port 112 of the housing 11 and the second outer cylinder opening 132 of the outer cylinder 13. Therefore, when the second door 12b closes the second access port 112 at the front of the housing 11, the second door seal 14b prevents water from the outer cylinder 13 from entering the housing 11, and simultaneously prevents water from the outer cylinder 13 from overflowing from the second access port 112 of the housing 11.

[0112] For ease of description, the two rollers are defined as the first roller 15 and the second roller 16, respectively.

[0113] In this assembly, a first roller 15 is rotatably disposed within one of the outer cylinders 13. The first roller 15 is rotatable relative to the outer cylinder 13. The interior of the first roller 15 defines a first garment processing chamber 1511 for receiving garments. The first roller 15 is provided with a first garment inlet 1521 communicating with the first garment processing chamber 1511, and the first garment inlet 1521 is disposed facing the opening 131 of the first outer cylinder. One of the cylinder assemblies 13a includes one of the outer cylinders 13 and the first roller 15. The opening 13b of the cylinder assembly 13a includes the first outer cylinder opening 131 and the first garment inlet 1521.

[0114] In this application, the first drum 15 is generally cylindrical to facilitate rotation relative to one of the outer drums 13, and is typically made of stainless steel. The peripheral wall of the first drum 15 has water passage holes (not shown in the figure), through which washing liquid can enter the first garment processing chamber 1511 of the first drum 15. The first garment processing chamber 1511 is used to hold garments to be washed. When the first drum 15 rotates relative to the outer drum 13, it can perform the washing function on the garments in the first garment processing chamber 1511. It should be noted that in other embodiments, the first garment processing chamber 1511 can also be used for drying clothes, such as in a washer-dryer combo.

[0115] Typically, the first loading port 1521 and the first outer drum opening 131 of the multi-drum garment handling device 100 are coaxially arranged, and the diameter of the first loading port 1521 is larger than that of the first outer drum opening 131, so that after the first door 12a is opened, the clothes can be sequentially placed into the first garment handling chamber 1511 of the first drum 15 through the first loading port 111, the first outer drum opening 131 and the first loading port 1521 for washing, dehydration and other operations.

[0116] The second roller 16 is rotatably disposed within another outer roller 13. The second roller 16 is rotatable relative to the other outer roller 13. The interior of the second roller 16 defines a second garment processing chamber 1611 for receiving garments, and the second roller 16 is provided with a second garment inlet 1621 communicating with the second garment processing chamber 1611. The second garment inlet 1621 is disposed facing the opening 132 of the second outer roller. The other roller assembly 13a includes another outer roller 13 and the second roller 16. The opening 13b of the roller assembly 13a includes the second outer roller opening 132 and the second garment inlet 1621.

[0117] In this application, the second drum 16 is generally cylindrical to facilitate rotation relative to the outer drum 13, and is typically made of stainless steel. The peripheral wall of the second drum 16 has water passage holes (not shown in the figure), through which washing liquid can enter the second garment processing chamber 1611 of the second drum 16. The second garment processing chamber 1611 is used to hold garments to be washed. When the second drum 16 rotates relative to the outer drum 13, it can perform the washing function on the garments in the second garment processing chamber 1611. It should be noted that in other embodiments, the second garment processing chamber 1611 can also be used to dry clothes, such as in a washer-dryer combo.

[0118] Typically, the second loading port 1621 and the second outer drum opening 132 of the multi-drum garment handling device 100 are coaxially arranged, and the diameter of the second loading port 1621 is larger than that of the second outer drum opening 132, so that after the second door 12b is opened, the clothes can be sequentially placed into the second garment handling chamber 1611 of the second drum 16 through the second loading port 112, the second outer drum opening 132 and the second loading port 1621 for washing, dehydration and other operations.

[0119] Since the multi-roller clothing processing device 100 provided in this application embodiment has relatively independent clothing processing chambers and a first roller 15 and a second roller 16 arranged side by side in the left and right direction, it can achieve the purpose of sorting and washing clothes to meet people's personalized requirements.

[0120] In some embodiments, such as Figures 4 to 6 As shown, the two cylinder assemblies 13a are arranged side by side in the left-right direction, and the first roller 15 and the second roller 16 are arranged side by side in the left-right direction.

[0121] In some embodiments, the first roller 15 includes a first cylinder body 151 and a first cylinder front end member 152. The interior of the first cylinder body 151 defines a first garment processing cavity 1511 for receiving garments, and the first cylinder body 151 is provided with a first cylinder opening (not shown) communicating with the first garment processing cavity 1511. The first cylinder front end member 152 is disposed at the first cylinder opening and is provided with a first garment loading port 1521 facing the first loading port 111. This allows the first cylinder front end member 152 to enhance the structural strength of the first cylinder body 151 and improve the structural strength of the first roller 15.

[0122] In some embodiments, the second roller 16 includes a second cylinder 161 and a second front end member 162. The interior of the second cylinder 161 defines a second garment processing cavity 1611 for receiving garments, and the second cylinder 161 is provided with a second cylinder opening (not shown) communicating with the second garment processing cavity 1611. The second front end member 162 is disposed at the second cylinder opening and has a second garment loading port 1621 facing the second loading port 112. This allows the second front end member 162 to enhance the structural strength of the second cylinder 161 and improve the structural strength of the second roller 16.

[0123] Understandably, the greater the length of the box 11 in the front-to-back direction and / or the width in the left-to-right direction, the larger the floor space occupied by the box 11. To reduce the floor space occupied by the box 11 and to achieve a compact design, the width of the box 11 in the left-to-right direction is generally not too large. Meanwhile, the first roller 15 and the second roller 16 are arranged side-by-side in the left-to-right direction, so that the maximum diameter of the first cylinder 151 and the second cylinder 161 is approximately 220mm. Furthermore, to facilitate the user's loading and unloading of clothing from the first cylinder 151 and the second cylinder 161, the first loading port 1521 of the first cylinder's front end member 152 and the second loading port 1621 of the second cylinder's front end member 162 must maintain a certain straightness. The diameters of the first loading opening 1521 of the first tube front end piece 152 and the second loading opening 1621 of the second tube front end piece 162 cannot be too small, usually not less than 160mm. This results in the first tube front end piece 152 and the second tube front end piece 162 having a radial width of only about (220-160)mm / 2=30mm in the corresponding tube body. As a result, the tube front end pieces (i.e., the first tube front end piece 152 and the second tube front end piece 162) are unable to prevent the clothes in the tube body (i.e., the first tube body 151 and the second tube body 161) from moving forward. This makes it easy for the clothes to be caught in the gap between the tube front end piece and the door seal (i.e., the first door seal 14a and the second door seal 14b), resulting in the problem of fabric being caught.

[0124] In this application, the first tubular body 151 is inclined downwards from top to bottom in the direction from the front side of the box body 11 to the rear side of the box body 11, for example, gradually inclined downwards. This allows the front end member 152 of the first tubular body to be higher than the bottom of the first tubular body 151 away from the front end member 152. Consequently, the first garment inlet 1521 can be higher than the bottom of the first tubular body 151 away from the front end member 152. This allows clothing inserted into the first garment inlet 1521 to be guided along the inner wall of the first tubular body 151 to the bottom of the first tubular body 151. In other words, it is inclined downwards from top to bottom in the direction from the front side of the box body 11 to the rear side of the box body 11. The first drum 151 not only guides the clothes put in from the first loading port 1521 to the bottom of the first drum 151, preventing them from piling up at the first loading port 1521 and facilitating the loading of clothes; it also ensures that the clothes in the first drum 151 tend to move towards the bottom of the first drum 151 when the multi-drum laundry handling device 100 is running, preventing the clothes in the first drum 151 from moving towards the first loading port 1521 and getting caught in the gap between the front end piece 152 of the first drum and the first door seal 14a. This effectively prevents the clothes from getting caught, thereby reducing the chance of damaging the clothes and improving the user's laundry experience.

[0125] The second roller 16 is inclined downwards from top to bottom in the direction from the front side of the housing 11 to the rear side of the housing 11, for example, gradually inclined downwards. This allows the front end member 162 of the second roller to be higher than the bottom of the second roller 161 away from the front end member 162. Consequently, the second loading port 1621 is also higher than the bottom of the second roller 161 away from the front end member 162. This allows clothing loaded into the second loading port 1621 to be guided along the inner wall of the second roller 161 to the bottom of the second roller 161. In other words, the second roller 16 is inclined downwards from top to bottom in the direction from the front side of the housing 11 to the rear side of the housing 11. The second drum 161 not only guides the clothes put in from the second loading port 1621 to the bottom of the second drum 16, preventing them from piling up at the second loading port 1621 and facilitating the loading of clothes; it also ensures that the clothes in the second drum 161 tend to move towards the bottom of the second drum 161 when the multi-drum laundry handling device 100 is running, preventing the clothes in the second drum 161 from moving towards the second loading port 1621 and getting caught in the gap between the front end piece 162 of the second drum and the second door seal 14b. This effectively prevents the clothes from getting caught, thereby reducing the chance of damaging the clothes and improving the user's laundry experience.

[0126] For ease of description, this application, as Figure 5 and Figure 6As shown, the inclination angle between the axis of the first cylinder 151 and the front-rear direction is defined as θ1, and the inclination angle between the axis of the second cylinder 161 and the front-rear direction is defined as θ2. It is understood that the above definitions are merely for the convenience of description in this application and should not be used to limit the scope of protection of this application.

[0127] If θ1 < 2°, when clothes are being loaded, the inner wall of the first cylinder 151 cannot effectively guide the clothes put in from the first loading port 1521 to the bottom of the first cylinder 151, making it easy for clothes to accumulate at the first loading port 1521, which is not conducive to loading clothes; moreover, when the multi-cylinder clothing handling device 100 is running, there is still a risk that clothes will move toward the first loading port 1521 and get into the gap between the front end of the first cylinder 152 and the first door seal 14a.

[0128] In some embodiments, θ1≥2° not only ensures that the inner wall of the first drum 151 can effectively guide the clothes put in from the first loading port 1521 to the bottom of the first drum 151, avoiding accumulation at the first loading port 1521 and facilitating the loading of clothes; it also makes the clothes in the first drum 151 tend to move towards the bottom of the drum when the multi-drum clothes handling device 100 is running, preventing the clothes in the first drum from moving towards the first loading port 1521 and being caught in the gap between the front end member 152 of the first drum and the first door seal 14a, thereby effectively preventing the occurrence of cloth entrapment, thus reducing the probability of damage to clothes and improving the user's laundry experience.

[0129] If θ1 > 6°, the first cylinder 151 will be too tilted, which will easily generate large vibration noise during operation.

[0130] In some embodiments, θ1 ≤ 6°. This setting can prevent the cylinder from tilting excessively, allowing the cylinder to operate smoothly and reducing vibration and noise.

[0131] In some embodiments, 2°≤θ1≤6°. For example, 2°≤θ1≤3°, 3°≤θ1≤4°, 4°≤θ1≤5°, or 5°≤θ1≤6°. Exemplarily, θ1 = 2°, 2.5°, 3°, 3.5°, 4°, 4.5°, 5°, 5.5°, or 6°, etc.

[0132] This design not only ensures that the inner wall of the first drum 151 can effectively guide the clothes put in from the first loading port 1521 to the bottom of the first drum 151, preventing them from piling up at the loading port 1521 and facilitating the loading of clothes; it also ensures that when the multi-drum laundry handling device 100 is running, the clothes in the first drum 151 tend to move towards the bottom of the first drum 151, preventing the clothes in the first drum from moving towards the first loading port 1521 and getting caught in the gap between the front end piece 152 of the first drum and the first door seal 14a, thus effectively preventing the clothes from getting caught, thereby reducing the chance of damaging the clothes and improving the user's laundry experience; it also ensures that the first drum 151 operates smoothly and reduces vibration noise.

[0133] Similarly, if θ2 < 2°, when clothes are being loaded, the inner wall of the second cylinder 161 cannot effectively guide the clothes put in from the second loading port 1621 to the bottom of the second cylinder 161, making it easy for clothes to accumulate at the second loading port 1621, which is not conducive to loading clothes; moreover, when the multi-cylinder clothing handling device 100 is running, there is still a risk that clothes will move toward the second loading port 1621 and be trapped in the gap between the second cylinder front end piece 162 and the second door seal 14b.

[0134] In some embodiments, θ2≥2° not only ensures that the inner wall of the second drum 161 can effectively guide the clothes put in from the second loading port 1621 to the bottom of the second drum 161, avoiding accumulation at the second loading port 1621 and facilitating the loading of clothes; it also ensures that when the multi-drum laundry handling device 100 is running, the clothes in the second drum 161 tend to move towards the bottom of the drum, preventing the clothes in the second drum from moving towards the second loading port 1621 and being caught in the gap between the front end member 162 of the second drum and the second door seal 14b, thereby effectively preventing the cloth from getting caught, thus reducing the probability of damage to the clothes and improving the user's laundry experience.

[0135] If θ2 > 6°, the second cylinder 161 will be too tilted, which will easily generate large vibration noise during operation.

[0136] In some embodiments, θ2 ≤ 6°. This setting can prevent the cylinder from tilting excessively, allowing the cylinder to operate smoothly and reducing vibration and noise.

[0137] In some embodiments, 2°≤θ2≤6°. For example, 2°≤θ2≤3°, 3°≤θ2≤4°, 4°≤θ2≤5°, or 5°≤θ2≤6°. Exemplarily, θ2 = 2°, 2.5°, 3°, 3.5°, 4°, 4.5°, 5°, 5.5°, or 6°, etc.

[0138] This design not only ensures that the inner wall of the second drum 161 can effectively guide the clothes placed in through the second loading port 1621 to the bottom of the second drum 161, preventing them from piling up at the loading port 1621 and facilitating the loading of clothes; it also ensures that when the multi-drum laundry handling device 100 is running, the clothes in the second drum 161 tend to move towards the bottom of the second drum 161, preventing them from moving towards the second loading port 1621 and getting caught in the gap between the front end piece 162 and the second door seal 14b, thus effectively preventing the clothes from getting caught and reducing the chance of damaging the clothes, improving the user's laundry experience; it also ensures that the second drum 161 operates smoothly and reduces vibration noise.

[0139] For ease of description, this application, as Figure 6 and Figure 7 As shown, the axis of the cylinder assembly's centroid M on its radial cross-section is defined as the cylinder axis N. The distance from the centroid M to the cylinder axis N in the left-right direction is defined as d1, and the distance from the centroid M to the cylinder axis N in the up-down direction is defined as d2. The cylinder body has a front end face and a rear end face opposite each other in its axial direction. The distance from the centroid M of the cylinder assembly to the front end face of the cylinder body in the axial direction is defined as d3, and the distance from the centroid M of the cylinder assembly to the rear end face of the cylinder body is defined as d4. It is understood that the above definitions are merely for the convenience of description in this application and should not be used to limit the scope of protection of this application.

[0140] If d1 > 1mm, the cylinder assembly will generate a rotational torque due to external forces, making it difficult to achieve a static or balanced state in the left and right directions. It is prone to tilting or moving, which can easily generate vibration and noise.

[0141] In some embodiments, 0mm ≤ d1 ≤ 1mm, for example, 0mm ≤ d1 ≤ 0.1mm, 0.1mm ≤ d1 ≤ 0.3mm, 0.3mm ≤ d1 ≤ 0.5mm, 0.5mm ≤ d1 ≤ 0.7mm, 0.7mm ≤ d1 ≤ 0.9mm, or 0.9mm ≤ d1 ≤ 1mm. Exemplarily, d1 = 0mm, 0.1, 0.2, 0.3, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 0.95mm, or 1mm, etc.

[0142] This effectively prevents the cylinder assembly from generating rotational torque due to external forces, thus helping the cylinder assembly maintain a balanced state in the left and right directions, preventing tilting or movement, thereby avoiding unnecessary vibration or displacement during start-up or shutdown, and further reducing vibration and noise during the operation of the multi-cylinder clothing handling device.

[0143] If d2 > 40mm, the cylinder assembly will generate a rotational torque due to external forces, making it difficult to achieve a static or balanced state in the vertical direction. It is prone to tilting or moving, which can easily generate vibration and noise.

[0144] In some embodiments, 0mm ≤ d2 ≤ 40mm, for example, 0mm ≤ d1 ≤ 0.1mm, 0.1mm ≤ d1 ≤ 0.3mm, 0.3mm ≤ d1 ≤ 0.5mm, 0.5mm ≤ d1 ≤ 0.7mm, 0.7mm ≤ d1 ≤ 0.9mm, or 0.9mm ≤ d1 ≤ 1mm. For example, d1 = 0mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 0.95mm, or 1mm, etc.

[0145] This allows the center of gravity of the cylinder assembly to be easily adjusted to the preset position in the vertical direction, while effectively preventing the cylinder assembly from generating rotational torque due to external forces. This helps the cylinder assembly maintain a balanced state in the vertical direction, preventing tilting or movement, and thus avoiding unnecessary vibration or displacement during start-up or shutdown. Consequently, it can reduce vibration and noise during the operation of the multi-cylinder clothing handling device.

[0146] If d4 / d3 < 0.4, the front end face of the cylinder assembly deviates far from the center of mass of the cylinder assembly in the front-rear direction, resulting in a larger torque, which makes the front end of the cylinder assembly more prone to vibration and swaying.

[0147] In some embodiments, d4 / d3≥0.4 can reduce the torque from the front end face of the cylinder assembly to the center of mass of the cylinder assembly in the front-rear direction, thereby reducing the vibration and noise at the front end of the cylinder assembly.

[0148] If d4 / d3 > 0.6, the rear end face of the cylinder assembly will deviate far from the center of mass of the cylinder assembly in the front-rear direction, resulting in a larger torque and making the rear end of the cylinder assembly more prone to vibration and swaying.

[0149] In some embodiments, d4 / d3≤0.6 can reduce the torque from the rear end face of the cylinder assembly to the center of mass of the cylinder assembly in the front-rear direction, thereby reducing vibration and noise at the front end of the cylinder assembly.

[0150] In some embodiments, 0.4 ≤ d4 / d3 ≤ 0.6, for example, 0.4 ≤ d4 / d3 ≤ 0.42, 0.42 ≤ d4 / d3 ≤ 0.45, 0.45 ≤ d4 / d3 ≤ 0.47, 0.47 ≤ d4 / d3 ≤ 0.5, 0.5 ≤ d4 / d3 ≤ 0.53, 0.53 ≤ d4 / d3 ≤ 0.55, 0.55 ≤ d4 / d3 ≤ 0.58, or 0.58 ≤ d4 / d3 ≤ 0.6. For example, d4 / d3 = 0.4, 0.41, 0.42, 0.43, 0.44, 0.45, 0.46, 0.47, 0.48, 0.49, 0.5, 0.51, 0.52, 0.53, 0.54, 0.55, 0.56, 0.57, 0.58, 0.59, or 0.6, etc.

[0151] This design helps maintain the balance of the tubular assembly in the front-to-back direction, reducing vibration and noise during the operation of the multi-tubular garment handling device.

[0152] Because the drum assembly of this application is tilted, when the multi-drum garment processing device is running, such as during dehydration, the garments are mainly concentrated at the rear end of the drum assembly, resulting in greater vibration at the rear end of the drum assembly compared to the front end. Therefore, this application preferably uses 0.4≤d4 / d3≤0.5, so that the center of mass of the drum assembly can be shifted towards the rear end of the drum assembly, thereby reducing the torque from the rear end of the drum assembly to the center of mass of the drum assembly, which helps to reduce vibration and noise.

[0153] In some embodiments, such as Figure 8 As shown, the multi-tube clothing processing device provided in this application embodiment also includes at least two shock-absorbing components. The shock-absorbing component includes two shock absorbers 17. One end of the shock absorber 17 is connected to the bottom of the box, that is, one end of the shock absorber 17 is connected to the bottom plate 11e of the box, and the other end of the shock absorber 17 is connected to the outer peripheral side of the outer tube 13. The two shock absorbers 17 of at least one shock-absorbing component are located on both sides of an outer tube 13 in the left-right direction.

[0154] That is to say, when the number of damping components is the same as the number of outer cylinders 13, the two dampers 17 of one damping component are located on both sides of one outer cylinder in the left-right direction. For example, when there are two damping components and two outer cylinders 13, the two dampers 17 of one damping component are located on both sides of one outer cylinder 13 in the left-right direction, and the two dampers 17 of the other damping component are located on both sides of the other outer cylinder 13 in the left-right direction. When the number of damping components is greater than the number of outer cylinders 13, at least one outer cylinder 13 corresponds to at least two damping components. For example, when there are three damping components and two outer cylinders 13, the two dampers 17 of two damping components are located on both sides of one outer cylinder 13 in the left-right direction, and the two dampers 17 of the remaining damping component are located on both sides of the other outer cylinder 13 in the left-right direction.

[0155] The outer cylinder 13 is thus fixed to the bottom plate 11e of the housing by shock absorbers 17. As the main load-bearing component of the outer cylinder 13, the shock absorber 17 transmits vibrations primarily to the bottom plate 11e of the housing, effectively reducing the transmission of vibrations to the housing 11 and thus playing a role in shock absorption. This reduces vibration and noise during the operation of the multi-cylinder clothing handling device. Furthermore, each outer cylinder 13 can be supported by at least one shock absorber 17 on both sides in the left-right direction, thus ensuring stable support for each outer cylinder 13.

[0156] like Figure 9 As shown, there are two shock absorption components, and therefore four shock absorbers 17. Two shock absorbers 17 are located on the left and right sides of one of the outer cylinders 13, and the other two shock absorbers 17 are located on the left and right sides of the other outer cylinder 13. That is, each outer cylinder 13 is supported by at least one shock absorber 17 on both sides in the left and right direction, so that each outer cylinder 13 can be stably supported.

[0157] Optionally, one end of the shock absorber 17 can be fixed to the fixing device of the base plate 11e by fixing bolts, and the other end can be fixed to the fixing connector of the outer cylinder 13 by fixing bolts and screws.

[0158] Optionally, the shock absorber 17 may include an elongated damper and a sleeve, wherein the damper is made of rubber polymer material as the main raw material, is inserted into the sleeve, and can be stretched back and forth, and the bottom plate 11e of the housing and the outer cylinder 13 are respectively provided at both ends of the damper and the sleeve.

[0159] Because the first roller 15 and the second roller 16 in this application are inclined, in order to stably support the outer cylinder 13, in some embodiments, the shock absorber 17 is inclined from front to back in the direction from the bottom to the top of the housing, for example, gradually inclined from front to back. This can stably support the outer cylinder 13. Moreover, when the multi-cylinder garment handling device is operating, the excitation force (i.e., centrifugal force) of the inclined first roller 15 and the second roller 16 is decomposed into a component force in the front-back direction and a component force in the up-down direction. That is, compared with the cylinder that is horizontally arranged in the front-back direction, the inclined cylinder... The excitation force will have an additional component in the front-to-back direction, causing the shock absorber 17 to be tilted. This allows the force exerted by the shock absorber 17 on the tilted cylinder to be decomposed into components in the front-to-back direction and components in the up-down direction. In other words, compared to a shock absorber 17 that is vertically positioned in the up-down direction, the force exerted by the tilted shock absorber 17 on the tilted cylinder can have an additional component in the front-to-back direction, which can offset the front-to-back component of the excitation force of the tilted cylinder. This solves the problem of a large excitation force in the front-to-back direction caused by the tilted cylinder, thereby achieving a better shock absorption effect and reducing vibration and noise during the operation of the multi-cylinder clothing processing device.

[0160] For ease of description, this application defines the projection of the axis of the shock absorber 17 in the left-right direction as the first projection line, and the projection of the axis of the cylinder in the left-right direction as the second projection line, and so on. Figure 10 As shown, the angle between the first projection line and the second projection line is defined as α. It is understood that the above definition is merely for the convenience of description in this application and should not be used to limit the scope of protection of this application.

[0161] If α≤85°, the vertical component of the force exerted by the shock absorber 17 on the outer cylinder 13 will be too small, affecting the support effect of the shock absorber 17 on the outer cylinder 13 and easily generating large vibration noise during operation.

[0162] In some embodiments, α > 85°, such that the axis of the shock absorber 17 can be approximately perpendicular to the axis of the outer cylinder 13, so that the shock absorber 17 can stably support the outer cylinder 13 and reduce vibration noise.

[0163] If α ≥ 95°, the shock absorber 17 will be vertically installed, so the shock absorber 17 only exerts a force on the inclined cylinder in the vertical direction, and does not exert a force in the front-back direction. As a result, the shock absorber 17 is unable to counteract the front-back component of the excitation force of the inclined cylinder, resulting in poor shock absorption effect of the shock absorber 17. Consequently, the multi-cylinder clothing processing device is prone to generating large vibration noise during operation.

[0164] In some embodiments, α < 95°. This setting ensures that the force exerted by the shock absorber 17 on the inclined cylinder can be decomposed into components in the front-to-back direction and components in the up-to-down direction. The front-to-back component of the force exerted by the shock absorber 17 on the inclined cylinder can be used to counteract the front-to-back component of the excitation force of the inclined cylinder, thereby solving the problem of large excitation force in the front-to-back direction caused by the inclined roller.

[0165] In some embodiments, 85° < α < 95°. For example, 85° < α ≤ 87°, 87° ≤ α ≤ 89°, 89° ≤ α ≤ 91°, 91° ≤ α ≤ 93°, or 93° ≤ α < 95°. Exemplarily, α = 85°, 86°, 87°, 88°, 89°, 90°, 91°, 92°, 93°, 94°, 94.5°, or 94.8°, etc.

[0166] This configuration allows the axis of the shock absorber 17 to be approximately 90° to the axis O of the cylinder. This not only ensures that the shock absorber 17 can stably support the outer cylinder 13, but also ensures that the force exerted by the shock absorber 17 on the inclined cylinder can be decomposed into components in the front-to-back direction and components in the up-and-down direction. The front-to-back component of the force exerted by the shock absorber 17 on the inclined cylinder can be used to counteract the front-to-back component of the excitation force of the inclined cylinder, thus solving the problem of large excitation force in the front-to-back direction caused by the inclined roller. This results in better shock absorption and reduces vibration and noise during the operation of the multi-cylinder clothing handling device 100.

[0167] In some embodiments, such as Figure 10 As shown in the embodiment of this application, the multi-tube garment processing device further includes at least four suspension spring assemblies 18. One end of each suspension spring assembly 18 is connected to the top of the housing, and the other end is connected to the outer peripheral side of the outer tube 13. At least two suspension spring assemblies 18 are located on both sides of an outer tube 13 in the left-right direction. That is to say, each outer tube 13 is connected to at least one suspension spring assembly 18 on one side in the left-right direction.

[0168] In this way, the outer cylinder 13 can be suspended on the box body by the suspension spring assembly 18, so that the vibration is mainly transmitted to the top of the box body through the suspension spring assembly 18, which effectively reduces the transmission of vibration to the box body and plays a role in shock absorption, thereby reducing the vibration and noise of the multi-cylinder clothing processing device during operation.

[0169] In other words, the suspension spring assembly 18 is located on the side of the outer cylinder 13 in the left-right direction, connected to the outer cylinder 13 and the housing, bearing a certain weight of the cylinder assembly, and at the same time playing the role of balancing the cylinder assembly and reducing the vibration of the cylinder assembly.

[0170] For ease of description, this application, as Figure 9As shown, on a projection plane perpendicular to the front-to-back direction, the angle between the axis of the suspension spring assembly 18 and the vertical direction is defined as β. It is understood that the above definition is merely for the convenience of this application's description and should not be used to limit the scope of protection of this application.

[0171] If β < 5°, the force exerted by the suspension spring assembly 18 on the cylinder assembly in the left-right direction is too small, making it difficult to maintain the stability of the cylinder assembly in the left-right direction.

[0172] In some embodiments, β≥5° can prevent the force exerted by the suspension spring assembly 18 on the cylinder assembly from being too small in the left and right directions, so that the suspension spring assembly 18 can maintain the stability of the cylinder assembly in the left and right directions, making it easier for the cylinder assembly to reach a balanced state.

[0173] If β > 20°, the force exerted by the suspension spring assembly 18 on the cylinder assembly in the vertical direction becomes smaller, making it difficult to maintain the stability of the cylinder assembly in the vertical direction.

[0174] In some embodiments, β≤20° can prevent the force exerted by the suspension spring assembly 18 on the cylinder assembly from being too small in the vertical direction, so that the suspension spring assembly 18 can maintain the stability of the cylinder assembly in the vertical direction, making it easier for the cylinder assembly to reach a balanced state.

[0175] In some embodiments, 5°≤β≤20°, for example, 5°≤β≤8°, 8°≤β≤10°, 10°≤β≤12°, 12°≤β≤15°, 15°≤β≤18°, or 18°≤β≤20°. For example, β = 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, or 20°, etc.

[0176] This configuration ensures that the force component of the suspension spring assembly 18 in the vertical direction is large enough to maintain the stability of the cylinder assembly in the vertical direction, while also preventing the force component of the suspension spring assembly in the horizontal direction from being too small, thus enabling the suspension spring assembly to maintain the stability of the cylinder assembly in the horizontal direction. This facilitates the cylinder assembly to reach a balanced state, preventing the cylinder assembly from tilting or moving, thereby avoiding unnecessary vibration or displacement during start-up or shutdown. It can achieve a better shock absorption effect and reduce vibration and noise during the operation of the multi-cylinder clothing processing device.

[0177] like Figure 10 As shown, there are at least four suspension spring assemblies 18. Each outer cylinder 13 is connected to a suspension spring assembly 18 on both sides in the left and right directions, so that each outer cylinder 13 is pulled by a suspension spring assembly 18 on both sides in the left and right directions, thereby enabling the outer cylinder 13 to be stably suspended on the box body 11.

[0178] There are at least three crossbeams 11g, and the at least three crossbeams 11g are respectively connected to the main body of the box. The at least three crossbeams are arranged in the left and right direction, and the at least three crossbeams are the first crossbeam, the middle crossbeam and the last crossbeam in the left and right direction. The first crossbeam and the last crossbeam are both connected to a suspension spring assembly 18, and the middle crossbeam is connected to at least one suspension spring assembly 18.

[0179] In one exemplary configuration, the intermediate crossbeam is connected to two suspension spring assemblies. There are four suspension spring assemblies 18, with two assemblies 18 connected to the left and right sides of one outer cylinder 13, and the other two assemblies 18 connected to the left and right sides of another outer cylinder 13. In this case, there are three crossbeams 11g and one intermediate crossbeam, which is connected to the two suspension spring assemblies 18. Alternatively, when the multi-cylinder garment handling device has three outer cylinders 13, there are six suspension spring assemblies 18, with two assemblies 18 connected to the left and right sides of one outer cylinder 13, two assemblies 18 connected to the left and right sides of another outer cylinder 13, and the remaining two assemblies 18 connected to the left and right sides of the remaining outer cylinder 13. In this case, there are four crossbeams 11g and two intermediate crossbeams, each intermediate crossbeam connected to two suspension spring assemblies 18.

[0180] In another exemplary configuration, the intermediate crossbeam is connected to a suspension spring assembly 18, wherein the number of crossbeams 11g is the same as the number of suspension spring assemblies 18, for example, as... Figure 9 As shown, there are four suspension spring assemblies 18, two of which are respectively connected to the two sides of one outer cylinder 13 in the left-right direction, and the other two suspension spring assemblies 18 are respectively connected to the two sides of another outer cylinder 13 in the left-right direction. In this case, as... Figure 8 and Figure 9 As shown, the box has four crossbeams 11g, with two in the middle. The four crossbeams 11g are connected to the main body of the box, and the four crossbeams 11g are arranged in the left and right direction. Each suspension spring assembly 18 is connected to a crossbeam 11g, that is, each suspension spring assembly 18 is suspended on a crossbeam 11g.

[0181] Understandably, if the housing 11 has three crossbeams 11g, the two side crossbeams 11g (i.e., the front and rear crossbeams) have reserved connection points for one suspension spring assembly 18, while the middle crossbeam 11g (i.e., the middle crossbeam) needs to reserve connection points for two suspension spring assemblies 18. This results in a different structure for the middle crossbeam compared to the front and rear crossbeams, requiring different molds to manufacture it, thus increasing design costs. Therefore, this application uses four crossbeams 11g, ensuring a one-to-one correspondence between the crossbeams 11g and the suspension spring assemblies 18. This facilitates standardized design of the crossbeams 11g, ensuring consistent structure and enabling mass production. It avoids the need to design numerous different molds to manufacture the crossbeams 11g, reducing the use of different molds and lowering design costs.

[0182] Optionally, hooks are provided at both ends of the suspension spring assembly 18. One end of the suspension spring assembly 18 is used to hang on the crossbeam 11g, and the other end of the suspension spring assembly 18 is used to hang on the outer cylinder 13.

[0183] In some embodiments, such as Figure 10 As shown, the suspension spring assembly 18 provided in this embodiment includes a first suspension spring 181 and a second suspension spring 182. One end of the first suspension spring 181 is connected to the top of the housing, that is, one end of the first suspension spring 181 is connected to the crossbeam 11g, and the other end of the first suspension spring 181 is connected to the outer peripheral side of the outer cylinder 13. One end of the second suspension spring 182 is connected to the top of the housing 11, that is, one end of the second suspension spring 182 is connected to the crossbeam 11g, and the other end of the second suspension spring 182 is connected to the outer peripheral side of the outer cylinder 13. The second suspension spring 182 and the first suspension spring 181 are located on the same side of the outer cylinder 13 in the left-right direction, and the second suspension spring 182 and the first suspension spring 181 are arranged in the front-back direction; in the direction from the bottom of the housing 11 to the top of the housing 11, one of the first suspension spring 181 and the second suspension spring 182 is inclined from back to front, for example, gradually inclined from back to front, and the other of the first suspension spring 181 and the second suspension spring 182 is inclined from front to back, for example, gradually inclined from front to back.

[0184] Understandably, when the multi-tube garment processing device is working, if the excitation force of the inclined tube in the front-to-back direction is forward, the tube tends to move forward, which will stretch the suspension springs that are inclined from front to back. This allows the suspension springs to exert a backward component of the force on the inclined tube in the front-to-back direction, thus counteracting the forward component of the excitation force of the inclined tube in the front-to-back direction. Conversely, if the excitation force of the inclined tube in the front-to-back direction is backward, the tube tends to move backward, which will stretch the suspension springs that are inclined from back to front. This allows the suspension springs to exert a forward component of the force on the inclined tube in the front-to-back direction, thus counteracting the backward component of the excitation force of the inclined tube in the front-to-back direction. Therefore, whether the excitation force of the inclined tube in the front-to-back direction is forward or backward, the suspension spring assembly 18 can achieve a shock absorption effect, improving the shock absorption effect of the suspension spring assembly 18.

[0185] It is understood that in other embodiments, the first suspension spring 181 and the second suspension spring 182 are tilted in the same direction, that is, in the direction from the bottom of the housing 11 to the top of the housing 11, both the first suspension spring 181 and the second suspension spring 182 are tilted from back to front, or both the first suspension spring 181 and the second suspension spring 182 are tilted from front to back. However, with this arrangement, the suspension spring assembly 18 can only exert a backward or forward component of the force on the inclined cylinder in the front-back direction, and cannot simultaneously take into account the random forward and backward components of the excitation force of the inclined cylinder in the front-back direction, resulting in poor shock absorption.

[0186] In this application, in the front-rear direction, the first suspension spring 181 is closer to the front side of the housing 11 than the second suspension spring 182.

[0187] As a first exemplary embodiment, such as Figure 10 As shown, in the direction from the bottom of the box to the top of the box, the first suspension spring 181 is inclined from front to back, for example, gradually inclined from front to back, and the second suspension spring 182 is inclined from back to front, for example, gradually inclined from back to front.

[0188] As a second exemplary embodiment, such as Figure 11 As shown, in the direction from the bottom of the box to the top of the box, the first suspension spring 181 is inclined from back to front, for example, gradually inclined from back to front, and the second suspension spring 182 is inclined from front to back, for example, gradually inclined from front to back.

[0189] In both of the above embodiments, the suspension spring assembly 18 can achieve a shock absorption effect, whether the component of the excitation force of the inclined cylinder in the front-rear direction is forward or backward. However, in the second embodiment, the connection points of the first suspension spring 181 and the outer cylinder 13, and the connection points of the second suspension spring 182 and the outer cylinder 13 are distributed at both ends of the outer cylinder 13. These connection points are relatively far from the center of mass of the outer cylinder 13, causing the outer cylinder 13 to generate torque and tend to rotate. This increases the probability of the outer cylinder 13 rotating, making it unstable and prone to vibration and noise. Therefore, this application prefers the second embodiment described above. In this embodiment, the connection points of the first suspension spring 181 and the outer cylinder 13, and the connection points of the second suspension spring 182 and the outer cylinder 13 are concentrated in the middle of the outer cylinder 13. Thus, the connection points of the first suspension spring 181 and the outer cylinder 13, and the connection points of the second suspension spring 182 and the outer cylinder 13 are relatively close to the center of mass of the outer cylinder 13. This reduces or avoids the rotational torque generated by the force of the first suspension spring 181 and the second suspension spring 182 on the outer cylinder 13, thereby reducing the probability of the outer cylinder 13 rotating, improving the fixed stability of the outer cylinder 13, and reducing the generation of vibration noise.

[0190] In some embodiments, such as Figure 11 and Figure 12 As shown, the axes of the first suspension spring 181 and the second suspension spring 182 intersect at the first point A. On the projection plane perpendicular to the left and right direction, the line segment connecting the first point A and the center of mass M of the cylinder assembly is the first connecting line, which is parallel to the up and down direction.

[0191] This configuration ensures that the point of application of the combined force of the first suspension spring 181 and the second suspension spring 182 on the cylinder assembly is zero or approximately zero in the front-to-back direction from the center of mass M of the cylinder assembly. This effectively prevents the cylinder assembly from generating rotational torque due to the forces of the first suspension spring 181 and the second suspension spring 182, thus maintaining a balanced state and preventing the cylinder assembly from tilting or moving. This avoids unnecessary vibration or displacement during start-up or shutdown, resulting in better shock absorption and reducing vibration and noise during the operation of the multi-cylinder clothing processing device.

[0192] In some embodiments, the first suspension spring 181 and the second suspension spring 182 are symmetrically arranged about a first straight line, the first straight line passes through a first point A, and on a projection plane perpendicular to the left and right direction, the first straight line is perpendicular to the axis of the cylinder assembly.

[0193] Because of the tilted arrangement of the tubular assembly, the clothes are concentrated at the rear end of the tubular assembly during the operation of the multi-tubular garment processing device, resulting in greater vibration at the rear end. By decomposing the resultant force of the tubular assembly on the first suspension spring 181 and the second suspension spring 182 in the front-to-back direction, a rearward component force is generated. This allows the suspension spring assembly 18 to effectively dampen the rear end of the tubular assembly, thereby better controlling the vibration of the tilted tubular assembly at the rear end. This effectively reduces the vibration generated during the operation of the whole machine, lowers the probability of collision between the tubular assembly and the housing and the operating noise, and improves the performance and reliability of the product.

[0194] For ease of description, this application defines the angle between the first suspension spring and the first straight line as γ1, and the angle between the second suspension spring and the first straight line as γ2, where γ2 = γ1. It is understood that the above definitions are merely for ease of description and should not be used to limit the scope of protection of this application.

[0195] If γ1 < 15°, the vertical component of the force exerted by the first suspension spring 181 and the second suspension spring 182 on the cylinder assembly is too small, making it difficult to maintain the stability of the cylinder assembly in the vertical direction.

[0196] In some embodiments, γ1≥15° can prevent the components of the first suspension spring 181 and the second suspension spring 182 from being too small in the vertical direction of the cylinder assembly, so that the suspension spring assembly 18 can maintain the stability of the cylinder assembly in the vertical direction, making it easier for the cylinder assembly to reach a balanced state.

[0197] If γ1 > 45°, the force exerted by the first suspension spring 181 and the second suspension spring 182 on the cylinder assembly will be reduced in the vertical direction, making it difficult to maintain the stability of the cylinder assembly in the vertical direction.

[0198] In some embodiments, 15°≤γ1≤45°, for example, 15°≤γ1≤18°, 18°≤γ1≤20°, 20°≤γ1≤25°, 25°≤γ1≤30°, 30°≤γ1≤33°, 33°≤γ1≤35°, 35°≤γ1≤38°, 38°≤γ1≤40°, 40°≤γ1≤42°, or 42°≤γ1≤45°. For example, γ1 = 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, or 45°, etc.

[0199] This configuration ensures that the vertical force components of the first and second springs 181 and 182 are both greater than their horizontal force components. This provides sufficient vertical force to maintain the stability of the cylinder assembly while preventing insufficient horizontal force components. This effectively counteracts the horizontal force component of the inclined cylinder assembly, addressing the issue of excessive horizontal force caused by the inclined assembly. It facilitates the cylinder assembly reaching a balanced state, preventing tilting or movement, and avoiding unnecessary vibration or displacement during startup or shutdown. This results in better shock absorption and reduces vibration and noise during operation of the multi-cylinder garment handling device.

[0200] In some embodiments, the top of the housing is provided with a first connecting protrusion 113 and a second connecting protrusion 114 protruding downwards, that is, the crossbeam 11g is provided with a first connecting protrusion 113 and a second connecting protrusion 114 protruding downwards. In the front-rear direction, the first connecting protrusion 113 is closer to the front side of the housing 11 than the second connecting protrusion 114. In the vertical direction, the height of the first connecting protrusion 113 protruding relative to the housing is less than the height of the second connecting protrusion 114 protruding relative to the housing, that is, the height of the first connecting protrusion 113 protruding relative to the crossbeam 11g is less than the height of the second connecting protrusion 114 protruding relative to the crossbeam 11g. One of the first connecting protrusion 113 and the second connecting protrusion 114 is connected to the first suspension spring 181, and the other of the first connecting protrusion 113 and the second connecting protrusion 114 is connected to the second suspension spring 182.

[0201] In this application, the outer cylinder 13 is inclined from top to bottom in the direction from the front side of the box to the rear side of the box. Therefore, the closer the outer cylinder 13 is to the front side of the box in the front-back direction, the closer it is to the top of the box. By making the height of the first connecting protrusion 113 near the front side of the box less than the height of the second connecting protrusion 114 away from the front side of the box, the first suspension spring 181 and the second suspension spring 182 can use suspension springs of the same length. This can achieve a universal design for the first suspension spring 181 and the second suspension spring 182, thereby helping to reduce the cost of the suspension spring assembly 18.

[0202] In some embodiments, the width of the first connecting protrusion 113 in the front-back direction decreases from top to bottom, thereby making the first connecting protrusion 113 approximately triangular. The triangular structure is relatively stable, which can enhance the structural stability of the first connecting protrusion 113, improve the load-bearing capacity of the first connecting protrusion 113, and extend the service life of the first connecting protrusion 113.

[0203] Similarly, the width of the second connecting protrusion 114 decreases from top to bottom in the front-back direction, which makes the second connecting protrusion roughly triangular. The triangular structure is relatively stable, thereby enhancing the structural stability of the second connecting protrusion 114, improving its load-bearing capacity, and extending its service life.

[0204] Understandably, the width of the first connecting protrusion 113 decreases from top to bottom in the front-back direction, which can make the first connecting protrusion 113 roughly triangular or roughly trapezoidal; similarly, the width of the second connecting protrusion 114 decreases from top to bottom in the front-back direction, which can make the second connecting protrusion 114 roughly triangular or roughly trapezoidal.

[0205] In some embodiments, the maximum width of the second connecting protrusion 114 in the front-rear direction is greater than the maximum width of the first connecting protrusion 113 in the front-rear direction. This avoids a situation where the height of the second connecting protrusion 114 is greater than the height of the first connecting protrusion 113, which would result in the width of the second connecting protrusion 114 being too small at a certain position in the front-rear direction. This ensures the structural stability of the second connecting protrusion 114, improves its load-bearing capacity, and extends its service life.

[0206] Since the multi-drum clothing handling device 100 in this application includes a first drum 15 and a second drum 16, the multi-drum clothing handling device 100 in this application is a twin-drum washing machine. Therefore, the multi-drum clothing handling device 100 in this application can usually only realize the washing or drying of two types of clothing at the same time. For multi-member families, its use is relatively limited, which is not conducive to the research and development and market promotion of the multi-drum clothing handling device 100 in the current washing machine market.

[0207] Therefore, in some embodiments, such as Figure 13 , Figure 14 and Figure 15 As shown, this application embodiment also provides a combined garment processing device 1000, which includes a first garment processing device 200 and a second garment processing device, wherein the second garment processing device is a multi-tube garment processing device 100 as described in any of the foregoing embodiments, and the second garment processing device is disposed on the first garment processing device 200.

[0208] In one exemplary embodiment, the first garment handling device 200 may further include a third drum 19, which may be disposed inside the housing of the multi-drum garment handling device 100 and located below the first drum 15 and the second drum 16 in the vertical direction, or located above the first drum 15 and the second drum 16 in the vertical direction. That is, the first drum 15, the second drum 16 and the third drum 19 may be arranged in a triangular or inverted triangular shape, thereby enabling the separate washing of garments of different sizes or with different washing requirements, avoiding cross-contamination, ensuring reliable operation of the washing work on the basis of reasonable planning of home space, facilitating the market promotion of the combined garment handling equipment 1000, and improving the convenience and reliability of people using multi-drum washing.

[0209] The third roller 19 can extend in the front-back direction of the multi-roller garment processing device 100, with its depth direction being able to extend along the front-back direction.

[0210] In another exemplary embodiment, the second clothing processing device is detachably mounted on top of the first clothing processing device 200. The first clothing processing device 200 can be a drum washing machine, dryer, or washer-dryer combo, etc. The functions of the first clothing processing device 200 and the second clothing processing device are independent of each other; that is, when the first clothing processing device 200 is processing clothing, the second clothing processing device may not be operating, and vice versa. Of course, the first clothing processing device 200 and the second clothing processing device can also process clothing simultaneously.

[0211] The first garment processing device 200 extends vertically along the second garment processing device, horizontally along the second garment processing device, and deeply along the second garment processing device. The second garment processing device is detachably mounted on top of the first garment processing device 200 in its vertical direction.

[0212] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0213] Furthermore, the embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the content of this specification should not be construed as a limitation of this application, and the protection scope of this application should be determined by the appended claims.
