[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 washing machine technology, and in particular to a multi-drum clothes handling device and a combined clothes handling 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] Most multi-roller garment handling devices on the market currently come with a large-capacity roller and several smaller rollers. To ensure the structural strength of the front end of the smaller rollers, a front-end fitting is usually installed at the opening of the smaller roller. However, to facilitate the user's loading and unloading of garments from the smaller rollers, the loading opening of the front-end fitting must have a certain diameter; that is, the diameter of the loading opening cannot be too small. Combined with the relatively small diameter of the smaller roller, this results in a relatively small radial width of the front-end fitting. Consequently, the front-end fitting is insufficient to prevent the garments from moving forward, causing them to easily get caught in the gap between the front-end fitting and the door seal, leading to fabric entrapment. Utility Model Content

[0006] This application discloses a multi-tube clothing handling device that can effectively prevent clothing from being caught in the gap between the front end of the tube and the door seal, reducing the chance of damage to the clothing.

[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 and a left-to-right 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 one outer cylinder is disposed inside the box, and the at least one outer cylinder is provided with at least two outer cylinder openings, each of the outer cylinder openings being disposed facing one of the take-out ports;

[0011] At least two door seals, each door seal being disposed between an outer cylinder opening and a dispensing / removing port, and each door seal being used to seal the gap between an outer cylinder opening and a dispensing / removing port;

[0012] At least two rollers, each of which is rotatably disposed within the outer cylinder, and each of the rollers comprises:

[0013] A cylindrical body, the interior of which defines a garment processing cavity for receiving garments, and the cylindrical body having an opening communicating with the garment processing cavity; and,

[0014] A front end piece of the cylinder is provided at the opening of the cylinder body, and the front end piece of the cylinder is provided with a clothes dispensing port facing the dispensing port;

[0015] Wherein, the at least two rollers are arranged side by side along the left-right direction;

[0016] The cylinder is inclined from top to bottom in the direction from the front side of the box to the rear side of the box.

[0017] The multi-drum garment processing device provided in this application has at least two drums with independent garment processing chambers, which can achieve the purpose of sorting and washing clothes to meet people's personalized requirements. Furthermore, this application also arranges the drum body to be inclined downwards from the front to the rear of the drum, so that the front end of the drum is higher than the bottom of the drum away from the front end, and the loading port is also higher than the bottom of the drum away from the front end. This allows clothes put into the loading port to be guided along the inner wall of the drum to the bottom of the drum. In other words, the drum body, inclined downwards from the front to the rear of the drum, not only guides clothes put into the loading port to the bottom of the drum, preventing them from piling up at the loading port and facilitating the loading of clothes, but also, when the multi-drum laundry handling device is running, makes the clothes in the drum tend to move towards the bottom of the drum, preventing them from moving towards the loading port and getting caught in the gap between the front end and the door seal. This effectively prevents clothes from getting caught, thereby reducing the chance of damage to clothes and improving the user's laundry experience.

[0018] In addition, by tilting the drum, the downward flow of clothes during washing is lengthened, which increases the tumbling force on the clothes and thus improves the washing efficiency.

[0019] As an optional implementation, in an embodiment of the first aspect of this application, the multi-tube clothing processing device further includes a shock-absorbing assembly, which includes two shock absorbers. One end of the shock absorber is connected to the bottom of the housing, and the other end of the shock absorber is connected to the outer peripheral side of the outer tube. The two shock absorbers of the shock-absorbing assembly are respectively located on both sides of the outer tube in the left-right direction.

[0020] The shock absorber is inclined from front to back in the direction from the bottom of the housing to the top of the housing.

[0021] This configuration provides stable support for the outer cylinder. Furthermore, during operation, the excitation force (centrifugal force) of the tilted cylinder is decomposed into components in the front-to-back and vertical directions. Compared to a cylinder positioned horizontally along the front-to-back direction, the tilted cylinder experiences an additional component in the front-to-back direction. This tilted design allows the force exerted by the shock absorber on the tilted cylinder to be decomposed into components in the front-to-back and vertical directions. In other words, compared to a shock absorber positioned vertically along the vertical direction, the tilted shock absorber exerts an additional component in the front-to-back direction, thus offsetting the front-to-back component of the tilted cylinder's excitation force. This addresses the issue of a large front-to-back excitation force caused by the tilted cylinder, resulting in better shock absorption and reduced vibration and noise during operation of the multi-cylinder garment processing device.

[0022] As an optional implementation, in an embodiment of the first aspect of this application, the orthogonal projection of the axis of the shock absorber in the left-right direction is configured as a first projection line, the orthogonal projection of the axis of the cylinder 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°.

[0023] This configuration ensures that the axis of the shock absorber and the axis of the cylinder are approximately 90° apart. This not only allows the shock absorber to stably support the outer cylinder, but also ensures that the force exerted by the shock absorber on the inclined cylinder 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 inclined cylinder can be used to counteract the front-to-back component of the inclined cylinder's excitation force, thus solving the problem of large front-to-back excitation force caused by the inclined cylinder. This results in better shock absorption and reduces vibration and noise during the operation of the multi-cylinder clothing handling device.

[0024] As an optional implementation, in the embodiment of the first aspect of this application, the box body also has a vertical direction, and the multi-tube clothing handling device further includes at least two suspension spring assemblies, one end of the suspension spring assembly is connected to the top of the box body, and the other end of the suspension spring assembly is connected to the outer peripheral side of the outer tube, and the at least two suspension spring assemblies are respectively located on both sides of the outer tube in the left-right direction;

[0025] The suspension spring assembly includes:

[0026] 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 outer cylinder; and...

[0027] 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 outer cylinder. The second suspension spring and the first suspension spring are located on the same side of the outer cylinder in the left-right direction, and the second suspension spring and the first suspension spring are arranged along the front-back direction.

[0028] 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.

[0029] 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. This stretches the suspension springs that are inclined from front to back, allowing the 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 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, stretching the suspension springs that are inclined from back to front. This stretches the 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 can achieve a shock absorption effect, improving the shock absorption performance of the suspension spring assembly.

[0030] 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.

[0031] This configuration ensures that the connections between the first and second suspension springs and the outer cylinder are concentrated in the middle of the outer cylinder. This makes the connections between the first and second suspension springs and the outer cylinder closer to the center of gravity of the outer cylinder, preventing torque from being generated in the outer cylinder, reducing the probability of the outer cylinder rotating, improving the stability of the outer cylinder, and reducing vibration and noise.

[0032] As an optional implementation, in the embodiment of the first aspect of this application, the top of the box body is provided with a first connecting protrusion and a second connecting protrusion protruding downwards. In the front-rear direction, the first connecting protrusion is closer to the front side of the box body than the second connecting protrusion. In the vertical direction, the height of the first connecting protrusion protruding relative to the box body is less than the height of the second connecting protrusion protruding relative to the box body.

[0033] One of the first connecting protrusion and the second connecting protrusion is connected to the first suspension spring, and the other of the first connecting protrusion and the second connecting protrusion is connected to the second suspension spring.

[0034] In this application, the outer cylinder 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 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 near the front side of the box less than the height of the second connecting protrusion away from the front side of the box, the first and second suspension springs can use suspension springs of the same length. This enables the universal design of the first and second suspension springs and reduces the cost of the suspension spring assembly.

[0035] As an optional implementation, in an embodiment of the first aspect of this application, the width of the first connecting protrusion in the front-back direction decreases from top to bottom, the width of the second connecting protrusion in the front-back direction decreases from top to bottom, and the maximum width of the second connecting protrusion in the front-back direction is greater than the maximum width of the first connecting protrusion.

[0036] By making the width of the first connecting protrusion decrease from top to bottom in the front-back direction, and the width of the second connecting protrusion decrease from top to bottom in the front-back direction, the first and second connecting protrusions can be made to be roughly triangular. Since the triangular structure is relatively stable, the structural stability of the first and second connecting protrusions can be enhanced, the load-bearing capacity of the first and second connecting protrusions can be improved, and the service life of the first and second connecting protrusions can be extended.

[0037] Meanwhile, since the height of the second connecting protrusion is greater than the height of the first connecting protrusion, this application also makes the maximum width of the second connecting protrusion in the front-back direction greater than the maximum width of the first connecting protrusion in the front-back direction, so as to avoid the situation where the width of the second connecting protrusion in the front-back direction is too small at a certain position, thereby ensuring the structural stability of the second connecting protrusion, improving the load-bearing capacity of the second connecting protrusion, and extending the service life of the second connecting protrusion.

[0038] As an optional implementation, in the embodiment of the first aspect of this application, there are at least two outer cylinders, the at least two outer cylinders are arranged side by side along the left-right direction, and each outer cylinder is provided with an outer cylinder opening, and each roller is disposed inside one outer cylinder;

[0039] There are at least four suspension spring assemblies, and each outer cylinder is connected to one suspension spring assembly on each of its two sides in the left-right direction;

[0040] The enclosure includes:

[0041] The main body of the box, wherein the at least two loading and unloading ports are located on the front side of the main body of the box in the front-rear direction; and

[0042] There are at least three crossbeams, which are respectively connected to the main body of the box. The at least three crossbeams are arranged along the left and right direction, and the at least three crossbeams are, in order, a head crossbeam, a middle crossbeam and a tail crossbeam in the left and right direction. The head crossbeam and the tail crossbeam are both connected to a suspension spring assembly, and the middle crossbeam is connected to at least one suspension spring assembly.

[0043] This design not only utilizes the crossbeams to enhance the structural strength of the main body of the box, but also provides mounting positions for the suspension spring assemblies, facilitating their installation.

[0044] As an optional implementation, in an embodiment of the first aspect of this application, the number of beams is the same as the number of suspension spring assemblies, and each suspension spring assembly is connected to one beam.

[0045] This configuration allows for a one-to-one correspondence between the crossbeam and the suspension spring assembly, facilitating standardized design of the crossbeam. This ensures a consistent crossbeam structure, enabling mass production and avoiding the need to design numerous different molds for crossbeam fabrication. It also reduces the use of different molds and lowers design costs.

[0046] As an optional implementation, in the embodiment of the first aspect of this application, there are at least two outer cylinders, which are arranged side by side along the left-right direction, and each outer cylinder has an outer cylinder opening, and each roller is disposed inside one outer cylinder; or,

[0047] There is one outer cylinder, and the at least two rollers share the same outer cylinder.

[0048] When each roller uses an independent outer cylinder, the vibration transmission between two adjacent rollers can be blocked to a certain extent, thereby reducing the resonance formed by multiple rollers, which in turn helps to reduce the overall vibration of the multi-roller garment processing device and reduce noise.

[0049] When two outer cylinders are integrally molded into a single structure, multiple rollers share the same outer cylinder, which reduces the number of parts. Moreover, since there are at least two rollers inside one outer cylinder, the weight is greater than that of a single roller inside each outer cylinder, increasing the overall weight of the cylinder assembly (i.e., the assembly formed by one outer cylinder and at least two rollers) and reducing vibration.

[0050] As an optional implementation, in the embodiment of the first aspect of this application, the inclination angle between the axis of the cylinder and the front-rear direction is 2°-6°.

[0051] When the above relationship is satisfied, it not only ensures that the inner wall of the drum can effectively guide the clothes put in from the loading port to the bottom of the drum, avoiding accumulation at the loading port and facilitating the loading of clothes; it also ensures that when the multi-drum laundry handling device is running, the clothes inside the drum tend to move towards the bottom of the drum, preventing the clothes inside the drum from moving towards the loading port and getting caught in the gap between the front part of the drum and the door seal, thus effectively preventing the cloth from getting caught, thereby reducing the chance of damaging the clothes and improving the user's laundry experience; it also prevents the drum from tilting excessively, allowing the drum to operate smoothly and reducing vibration noise.

[0052] Secondly, this application discloses a combined garment processing device, the combined garment processing device comprising:

[0053] First garment processing device;

[0054] 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.

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

[0056] The multi-drum garment processing device and combined garment processing equipment provided in this application have at least two drums with independent garment processing chambers, which can achieve the purpose of sorting and washing clothes to meet people's personalized requirements. Furthermore, this application also arranges the drum body to be inclined downwards from the front to the rear of the drum, so that the front end of the drum is higher than the bottom of the drum away from the front end, and the loading port is also higher than the bottom of the drum away from the front end. This allows the clothes put in through the loading port to be guided along the inner wall of the drum to the bottom of the drum. In other words, the drum body, which is inclined downwards from the front to the rear of the drum, not only guides the clothes put in through the loading port to the bottom of the drum, preventing them from piling up at the loading port and facilitating the loading of clothes, but also, when the multi-drum laundry handling device is running, makes the clothes in the drum tend to move towards the bottom of the drum, preventing the clothes in the drum from moving towards the loading port and getting caught in the gap between the front end of the drum and the door seal. This effectively prevents the clothes from getting caught, thereby reducing the chance of damage to the clothes and improving the user's laundry experience.

[0057] In addition, by tilting the drum, the downward flow of clothes during washing is lengthened, which increases the tumbling force on the clothes and thus improves the washing efficiency. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0079] The terms "first," "second," etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of this application, a first roller may be referred to as a second roller, and similarly, a second roller may be referred to as a first roller. Both the first roller and the second roller are rollers, but they are not the same roller.

[0080] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. 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.

[0081] 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. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] Multi-roller garment handling devices in related technologies typically include a large-capacity roller and several smaller rollers. To ensure the structural strength of the smaller rollers, a front-end component is usually installed at the opening of the smaller roller. However, to facilitate loading and unloading of garments from the smaller rollers, the loading opening of the front-end component must have a certain diameter, typically not less than 160mm. Furthermore, the diameter of the smaller roller is limited by the width of the housing and vibration, limiting it to approximately 220mm. This results in a relatively small radial width for the front-end component, typically only about (220-160)mm / 2 = 30mm. Consequently, the front-end component struggles to prevent the garments from moving forward, causing them to easily get caught in the gap between the front-end component and the door seal, leading to fabric entrapment.

[0088] In view of this, embodiments of this application provide a multi-tube garment handling device that can effectively prevent garments from being caught in the gap between the front end of the tube and the door seal.

[0089] Specifically, the multi-tube garment processing device provided in this application includes a housing, at least two doors, at least one outer tube, at least two door seals, and at least two rollers. The housing has at least two loading / unloading ports on its front side in the front-rear direction. Each door is rotatably connected to the housing to open or close a loading / unloading port. At least one outer tube is disposed inside the housing, and the at least one outer tube has at least two outer tube openings, each outer tube opening facing a loading / unloading port. Each door seal is disposed between an outer tube opening and a loading / unloading port, and each door seal is used to seal the gap between an outer tube opening and a loading / unloading port. Each roller is rotatably disposed inside the outer tube, and each roller includes a tube body and a front end member. The interior of the tube body defines a garment processing cavity for accommodating garments, and the tube body has a tube body opening communicating with the garment processing cavity. The front end member is disposed at the tube body opening and has a garment loading port facing the loading / unloading port. At least two rollers are arranged side by side in the left-right direction. In the direction from the front side of the housing to the rear side of the housing, the tube body is inclined from top to bottom.

[0090] 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.

[0091] Please see Figure 1 and Figure 2 , Figure 1 and Figure 2All 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] Please see Figures 4 to 6 The multi-tube garment processing device 100 provided in this application embodiment also includes an outer tube 13, which is disposed inside the housing 11, that is, the outer tube 13 is disposed in the accommodating space of the housing 11, and one end of the outer tube 13 is provided with a first outer tube opening 131 facing the first take-up port 111 and a second outer tube opening 132 facing the second take-up port 112, that is, the first outer tube opening 131 is opened facing the first take-up port 111, and the second outer tube opening 132 is opened facing the second take-up 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] Please continue reading. Figure 4 and Figure 5 The multi-tube clothing processing device 100 provided in this application embodiment also includes a first roller 15, which is rotatably disposed inside the outer tube 13. The first roller 15 can rotate relative to the outer tube 13. The interior of the first roller 15 defines a first clothing processing cavity 1511 for accommodating clothing. The first roller 15 is provided with a first clothing inlet 1521 communicating with the first clothing processing cavity 1511. The first clothing inlet 1521 is disposed facing the opening 131 of the first outer tube.

[0113] In this application, the first drum 15 is generally cylindrical to facilitate rotation relative to the outer drum 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.

[0114] 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.

[0115] Please continue reading. Figure 4 and Figure 5The multi-tube clothing processing device 100 provided in this application embodiment also includes a second roller 16, which is rotatably disposed inside the outer tube 13. The second roller 16 can rotate relative to the outer tube 13. The interior of the second roller 16 defines a second clothing processing cavity 1611 for accommodating clothing. The second roller 16 is provided with a second clothing inlet 1621 communicating with the second clothing processing cavity 1611. The second clothing inlet 1621 is disposed facing the opening 132 of the second outer tube.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] In some embodiments, such as Figures 4 to 6 As shown, the first roller 15 and the second roller 16 are arranged side by side in the left-right direction.

[0120] In some embodiments, the first roller 15 includes a first cylinder 151 and a first cylinder front end member 152. The interior of the first cylinder 151 defines a first garment processing cavity 1511 for receiving garments, and the first cylinder 151 has 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 has 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 151 and improve the structural strength of the first roller 15, and also to a certain extent prevents garments from escaping from the first garment processing cavity 1511.

[0121] Optionally, the front end part 152 of the first cylinder can be a ring structure, and its material can be a metal material, such as stainless steel, aluminum alloy, etc.

[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 has 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, and also to a certain extent prevents garments from escaping from the second garment processing cavity 1611.

[0123] Optionally, the second cylinder front end piece 162 can be a ring structure, and its material can be a metal material, such as stainless steel, aluminum alloy, etc.

[0124] 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 front end pieces (i.e., the first tube front end piece 152 and the second tube front end piece 162) cannot 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 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.

[0125] 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. That is, 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. 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 allows the clothes in the first drum 151 to tend to move towards the bottom of the first drum 151 when the multi-drum clothes handling device 100 is running, preventing the clothes in the first drum 151 from moving towards the first loading port 1521 and being 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.

[0126] 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.

[0127] For ease of description, this application, as Figure 5 and Figure 6 As 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.

[0128] 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.

[0129] 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.

[0130] If θ1 > 6°, the first cylinder 151 will be too tilted, which will easily generate large vibration noise during operation.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] If θ2 > 6°, the second cylinder 161 will be too tilted, which will easily generate large vibration noise during operation.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] In one exemplary embodiment, there may be two outer cylinders 13, arranged side by side in a left-right direction. The first roller 15 is disposed within one outer cylinder 13, and the second roller 16 is disposed within the other outer cylinder 13. That is, the first roller 15 and the second roller 16 utilize independent outer cylinders 13, which to some extent can block the vibration transmission between the first roller 15 and the second roller 16, thereby reducing the resonance formed by the first roller 15 and the second roller 16. This, in turn, helps to reduce the overall vibration of the multi-cylinder clothing handling device 100 and lower noise levels.

[0141] Another example is that the outer cylinder 13 can be one, which can be understood as two outer cylinders 13 integrally formed into a single structure. The first roller 15 and the second roller 16 share the same outer cylinder 13. This can reduce the number of parts. Moreover, since there are two rollers inside one outer cylinder 13, it is heavier than the way that there is only one roller inside one outer cylinder 13. This increases the overall weight of the cylinder assembly (i.e., the assembly formed by one outer cylinder 13 and two rollers) and reduces vibration.

[0142] In some embodiments, such as Figure 7 As shown, the multi-tube clothing processing device 100 provided in this application embodiment also includes a shock-absorbing assembly, which includes two shock absorbers 17. One end of the shock absorber 17 is connected to the bottom of the housing, that is, one end of the shock absorber 17 is connected to the bottom plate 11e of the housing, 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 assembly are respectively located on both sides of an outer tube 13 in the left-right direction.

[0143] In this way, the outer cylinder 13 can be fixed to the bottom plate 11e of the box body by the shock absorber 17. As the main load-bearing component of the outer cylinder 13, the shock absorber 17 mainly transmits the vibration to the bottom plate 11e of the box body through the shock absorber 17, which effectively reduces the transmission of vibration to the box body 11 and plays a role in shock absorption, thereby reducing the vibration and noise when the multi-cylinder clothing processing device is working.

[0144] When there are multiple outer cylinders 13, and the number of damping assemblies is the same as the number of outer cylinders 13, the two dampers 17 of one damping assembly are respectively located on both sides of the outer cylinder in the left-right direction, for example, as Figure 8 As shown, when the multi-tube garment processing device has two outer tubes 13, there are two shock-absorbing components, and therefore four shock absorbers 17. Two shock absorbers 17 are located on both sides of one outer tube 13 in the left-right direction, and the other two shock absorbers 17 are located on both sides of the other outer tube 13 in the left-right direction. Thus, each outer tube 13 can be supported by one shock absorber 17 on both sides in the left-right direction, thereby stably supporting each outer tube 13. When the number of shock-absorbing components is greater than the number of outer tubes 13, at least one outer tube 13 corresponds to at least two shock-absorbing components. For example, when there are three shock-absorbing components and two outer tubes 13, the two shock absorbers 17 of two shock-absorbing components are located on both sides of one outer tube 13 in the left-right direction, and the two shock absorbers 17 of the remaining shock-absorbing component are located on both sides of the other outer tube 13 in the left-right direction. Thus, each outer tube 13 can be supported by at least one shock absorber 17 on both sides in the left-right direction, thereby stably supporting each outer tube 13.

[0145] When the multi-tube garment processing device has one outer tube 13, and the number of shock-absorbing components is the same as the number of outer tubes 13, then there are two shock absorbers 17. One shock absorber 17 is located on one side of the outer tube 13 in the left-right direction, and the other shock absorber 17 is located on the other side of the outer tube 13 in the left-right direction. When the number of shock-absorbing components is greater than the number of outer tubes 13, the outer tube 13 is supported by at least two shock absorbers 17 on both sides in the left-right direction. Thus, the outer tube 13 is supported by at least one shock absorber 17 on both sides in the left-right direction, thereby stably supporting the outer tube 13.

[0146] 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.

[0147] 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.

[0148] 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, during operation, 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 excitation force of the inclined cylinder is greater. An additional force component in the front-to-back direction will be added, 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 a force component in the front-to-back direction and a force component in the up-down direction. In other words, compared to a shock absorber 17 that is vertically set in the up-down direction, the force exerted by the tilted shock absorber 17 on the tilted cylinder can have an additional force component in the front-to-back direction, which can offset the excitation force of the tilted cylinder in the front-to-back direction. 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.

[0149] 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 9As 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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-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, 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.

[0156] In some embodiments, such as Figure 9 As shown in the embodiment of this application, the multi-tube garment processing device further includes at least two 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, each outer tube 13 has at least one suspension spring assembly 18 connected to one side in the left-right direction.

[0157] 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.

[0158] 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, and bears a certain weight of the outer cylinder 13 and the roller, while also playing the role of balancing the outer cylinder and reducing its vibration.

[0159] When there are at least two outer cylinders 13, and at least two outer cylinders 13 are arranged side by side in the left-right direction, and each outer cylinder 13 is provided with an outer cylinder opening, and each roller is arranged inside an outer cylinder 13, 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-right direction, so that each outer cylinder 13 is pulled by a suspension spring assembly 18 on both sides in the left-right direction, thereby enabling the outer cylinder 13 to be stably suspended on the box body 11.

[0160] 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.

[0161] In one exemplary configuration, the intermediate crossbeam is connected to two suspension spring assemblies. For example, when the multi-tube garment handling device has two outer tubes 13, there are four suspension spring assemblies 18, with two suspension spring assemblies 18 connected to the left and right sides of one outer tube 13 respectively, and the other two suspension spring assemblies 18 connected to the left and right sides of the other outer tube 13 respectively. In this case, there are three crossbeams 11g and one intermediate crossbeam, which is connected to the two suspension spring assemblies 18. As another example, when the multi-tube garment handling device has three outer tubes 13, there are six suspension spring assemblies 18, with two suspension spring assemblies 18 connected to the left and right sides of one outer tube 13 respectively, the other two suspension spring assemblies 18 connected to the left and right sides of the other outer tube 13 respectively, and the remaining two suspension spring assemblies 18 connected to the left and right sides of the remaining outer tube 13 respectively. In this case, there are four crossbeams 11g and two intermediate crossbeams, with each intermediate crossbeam connected to two suspension spring assemblies 18.

[0162] 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 8 As shown, when the multi-tube garment handling device has two outer tubes 13, there are four suspension spring assemblies 18, two of which are respectively connected to the two sides of one outer tube 13 in the left-right direction, and the other two suspension spring assemblies 18 are respectively connected to the two sides of the other outer tube 13 in the left-right direction. In this case, as... Figure 7 and Figure 8 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.

[0163] 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.

[0164] When the multi-tube garment handling device has an outer tube 13, there are at least two suspension spring assemblies 18, one of which is connected to one side of the outer tube 13 in the left-right direction, and the other is connected to the other side of the outer tube 13 in the left-right direction. Thus, the outer tube 13 is pulled by at least one suspension spring assembly 18 on both sides in the left-right direction, so that the outer tube 13 can be stably suspended on the box.

[0165] 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.

[0166] In some embodiments, such as Figure 9 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.

[0167] 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.

[0168] 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.

[0169] 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.

[0170] As a first exemplary embodiment, such as Figure 9 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.

[0171] As a second 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.

[0172] In both of the above embodiments, whether the component of the excitation force of the inclined cylinder in the front-to-back direction is forward or backward, the suspension spring assembly 18 can achieve a shock absorption effect. However, in the second embodiment described above, 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, increasing the probability of rotation and making the outer cylinder 13 unstable and prone to vibration and noise. Therefore, this application prefers the first embodiment described above, which concentrates 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, in the middle of the outer cylinder 13. This makes the connection points of the first suspension spring and the outer cylinder, and the second suspension spring and the outer cylinder, closer to the center of mass of the outer cylinder 13, preventing the outer cylinder 13 from generating torque, reducing the probability of rotation, improving the stability of the outer cylinder 13, and reducing vibration and noise generation.

[0173] 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.

[0174] 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.

[0175] 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.

[0176] 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.

[0177] 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.

[0178] 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.

[0179] 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.

[0180] Therefore, in some embodiments, such as Figure 11 , Figure 12 and Figure 13 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.

[0181] 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.

[0182] 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.

[0183] 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.

[0184] 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.

[0185] 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.

[0186] 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.
