[0002] At present, the drum of a washing machine usually adopts a structure of an inner drum and an outer drum, that is, an outer drum is sleeved on the outer periphery of the inner drum, and the output end of a driving motor is fixedly connected with the inner drum after penetrating through the outer drum to drive the inner drum to rotate. The inner drum and the outer drum are both supported by cantilever beams, that is, the end of the inner drum connected with the driving motor and the end of the outer drum penetrated by the output end of the driving motor are both supported by bearings, and the other ends of the inner drum and the outer drum are both free ends without support. In this structure, the inner drum will vibrate and swing greatly during rotation, and the whole drum will also vibrate due to the influence of the inner drum. In addition, the outer drum occupies a large space, which affects the size design of the inner drum, resulting in a small volume of the inner drum. CONTENT OF THE UTILITY MODEL

[0003] The present application provides a clothes processing device, which can reduce the vibration of a rotating drum, improve the rotation stability of the rotating drum, and increase the volume of the inner drum without changing the overall volume of the clothes processing device.

[0006] The second end of the rotating drum is flexibly supported by the support and the constraint assembly, the cantilever beam support of the rotating drum is changed to a simply supported beam support, the constraint assembly can appropriately support and constrain the position of the second end of the rotating drum when the rotating drum rotates, effectively reducing the vibration of the rotating drum during rotation, and improving the rotation stability of the rotating drum. The traditional outer drum can be omitted, and the rotating drum can utilize the space originally occupied by the outer drum, thereby increasing the volume of the rotating drum without increasing the overall volume of the clothes processing device.

[0007] In a possible implementation, the constraint assembly comprises: a first sub-constraint member arranged at the second end of the rotating cylinder; and a second sub-constraint member arranged at the support, and configured to be arranged in cooperation with the first sub-constraint member to apply a force along a radial direction of the rotating cylinder to the first sub-constraint member to support the second end in suspension.

[0008] The two sub-constraint members are arranged in cooperation to reasonably configure the interaction of the force therebetween, and effectively improve the support efficiency between the first sub-constraint member and the second sub-constraint member.

[0009] In a possible implementation, the first sub-constraint member and the second sub-constraint member are both magnetic structures, and the polarities of the sides of the first sub-constraint member and the second sub-constraint member facing each other are the same, so that the second sub-constraint member is used to apply a repulsive force to the first sub-constraint member to support the second end in suspension.

[0010] The first sub-constraint member and the second sub-constraint member adopt magnetic structures, and the suspension support is realized by the interaction of magnetic fields, so that the contact between the second end and the support can be avoided, and the friction and noise can be reduced.

[0011] In a possible implementation, the first sub-constraint member comprises a plurality of first magnets, and the plurality of first magnets are arranged at the second end in a circumferential direction of the rotating cylinder; and the second sub-constraint member comprises a plurality of second magnets, and the plurality of second magnets are arranged at the support in the circumferential direction of the rotating cylinder.

[0012] The first magnets and the second magnets are arranged in the circumferential direction of the rotating cylinder, so that the second end can be uniformly stressed, and the stability of the magnetic suspension support can be improved.

[0013] In a possible implementation, one side of the rotating cylinder close to the support is provided with a first accommodating groove, and the first magnets are arranged in the first accommodating groove; and one side of the support close to the rotating cylinder is provided with a second accommodating groove, and the second magnets are arranged in the second accommodating groove.

[0014] The first magnets are arranged in the first accommodating groove, and the second magnets are arranged in the second accommodating groove, so that the magnets can be limited by the accommodating grooves, and the protrusions of the first magnets relative to the surface of the second end and the protrusions of the second magnets relative to the surface of the support can be reduced, and the mutual collision of the first magnets and the second magnets due to the swing of the rotating cylinder during the rotation of the rotating cylinder can be avoided.

[0015] In a possible implementation, the end face of the second end is provided with a first protruding ring, the first protruding ring is arranged around the axis of the rotating drum, the support is provided with a second protruding ring corresponding to the first protruding ring, and the second protruding ring is arranged around the axis of the rotating drum; the first sub-restricting members are arranged around the outer periphery of the first protruding ring at intervals, and the second sub-restricting members are arranged around the inner periphery of the second protruding ring at intervals.

[0016] By arranging the protruding rings for assembling the restricting members, the restricting members are appropriately away from the main body part of the support, and the restricting members can be prevented from being affected by the metal structure of the main body part of the support.

[0017] In a possible implementation, the support comprises: a first sub-support, which is arranged at the first end to support the first end; and a second sub-support, which is arranged at the second end to support the second end in suspension; the first sub-support and the second sub-support are oppositely arranged along the axial direction of the rotating drum and are connected to each other.

[0018] By arranging the first sub-support and the second sub-support to support the two ends of the rotating drum respectively, the supporting effect on the rotating drum can be improved.

[0019] In a possible implementation, the second sub-support is provided with an avoiding hole penetrating through along the axial direction of the rotating drum, and the second sub-support is sleeved around the outer periphery of the second end; the outer periphery of the second sub-support is provided with a first notch and a second notch, the first notch and the second notch are respectively located on the two sides of the second sub-support along a first direction, and the first notch and the second notch are both configured to expose at least part of the second end of the rotating drum; wherein the first direction is the width direction of the cabinet.

[0021] In a possible implementation, the drum body part further comprises: a first counterweight structure, which is arranged on one side of the second sub-support along a second direction; and a second counterweight structure, which is arranged on the other side of the second sub-support along the second direction; wherein the second direction is the height direction of the cabinet.

[0022] By arranging the counterweight structures on the second sub-support, the overall weight of the support can be increased, the inertia of the support is increased, and the influence of the vibration of the rotating drum on the support is reduced.

[0023] In a possible implementation, the drum body part further comprises: a third counterweight structure, which is arranged on the first sub-support.

[0024] Setting a third counterweight structure on the first sub-support can prevent the weight of the cylinder from being concentrated on the second sub-support, optimize the weight distribution of the cylinder, and prevent the cylinder from tilting.

[0026] The garment processing apparatus disclosed in this application, by incorporating a support and constraint assembly within the garment processing apparatus, flexibly suspends and supports the second end of a rotating cylinder, transforming the cantilever beam support of the rotating cylinder into a simply supported beam support. When the rotating cylinder rotates, the constraint assembly can appropriately support and constrain the position of the second end of the rotating cylinder, effectively reducing the vibration generated during rotation and improving the rotational stability of the rotating cylinder. Furthermore, the second end being suspended and supported by the support and constraint assembly eliminates the need for a traditional outer cylinder design, allowing the rotating cylinder to utilize the space originally occupied by the outer cylinder, thereby increasing the volume of the rotating cylinder without increasing the overall volume of the garment processing apparatus.

[0043] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0044] In the present application, the terms "upper", "lower", "bottom", "inner", "outer", "middle", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0045] In addition, in addition to indicating the orientation or positional relationship, the above-mentioned part of the terms can also be used to indicate other meanings, for example, the term "upper" can also be used to indicate a certain dependent relationship or connection relationship in some cases. Those skilled in the art can understand the specific meaning of these terms in the present application according to the specific situation. ​​​​​​

[0046] In addition, the terms "mount", "set", "provided with", "connected", "linked" should be understood broadly. For example, it can be fixed connection, detachable link, or integral structure; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication between two devices, elements or components. The specific meaning of the above terms in the present application can be understood according to the specific circumstances by those skilled in the art.

[0047] In addition, the terms "first", "second" and the like are mainly used to distinguish different devices, elements or components (the specific types and structures can be the same or different), and are not intended to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise stated, the meaning of "multiple" is two or more.

[0048] In laundry treating devices, such as drum washing machines, pulsator washing machines, clothes dryers and the like. Taking a drum washing machine as an example, the support of the drum is usually a cantilever beam type support. Specifically, one end (usually the rear end) of the inner drum is drivingly connected with the output shaft of the motor and is supported by the output shaft of the motor, and the other end (usually the front end) of the inner drum is a free end. Due to the fact that one end of the inner drum is not supported, affected by factors such as gravity, manufacturing tolerances of the product, and uneven distribution of laundry in the inner drum, when the inner drum rotates, the inner drum will vibrate / oscillate, and thus generate noise.

[0049] In addition, the outer side of the inner drum is usually also sleeved with an outer drum, the openings of the inner drum and the outer drum are consistent, the bottom of the outer drum is provided with a through hole for the output shaft of the motor to pass through and drivingly connect the inner drum, and the outer drum is supported on the output shaft of the motor through a rotating bearing. The outer drum is usually used to prevent water or cleaning agent in the inner drum from splashing into the circuit inside the laundry treating device, and serves as a drainage passage of the inner drum. Due to the limitation of the outer drum, the available space of the inner drum is greatly reduced, resulting in a smaller volume of the inner drum.

[0050] At present, in order to reduce the vibration of the inner drum during rotation, methods such as optimizing the structure and weight distribution of the inner drum, improving the coaxiality of the inner drum and the output shaft of the motor, and improving the supporting force of the output shaft of the motor on the inner drum are generally used. However, considering that the inner drum needs to rotate at high speed during part of the working process, sufficient mechanical strength is required, therefore, the structure shape and weight distribution of the inner drum are difficult to be greatly adjusted, and due to the reasons of mechanical strength and economy, the density of the material used to manufacture the inner drum is usually large, resulting in a large total weight of the inner drum. In addition, various tolerances accumulated during the manufacturing process of the product are difficult to avoid, which also reduces the coaxiality of the inner drum and the output shaft of the motor.

[0051] In addition, there are also ways to reduce the vibration of the entire device by setting counterweights on the outer drum, or setting springs or shock absorbers between the outer drum and the cabinet of the laundry treatment device. However, by adding counterweights or setting springs / shock absorbers on the outer drum, the internal space of the laundry treatment device is further occupied, the available space of the inner drum is limited, and the weight of the laundry treatment device itself is increased. In addition, adding counterweights or setting springs / shock absorbers on the outer drum cannot fundamentally reduce the vibration of the inner drum during rotation.

[0052] Therefore, the existing optimization methods have limited effect on reducing the vibration of the inner drum and increasing the volume of the inner drum, and it is difficult to meet the needs of actual production and use.

[0053] To solve the above technical problems, one embodiment of the present application provides a laundry treatment device, which is internally provided with a support and a constraint assembly, and the second end of the rotating drum is flexibly suspended and supported by the support and the constraint assembly, so that the cantilever beam support of the rotating drum is changed to a simply supported beam support. When the rotating drum rotates, the constraint assembly can appropriately support and constrain the position of the second end of the rotating drum, effectively reduce the vibration generated by the rotating drum during rotation, and improve the rotation stability of the rotating drum. In addition, since the rotating drum is designed without holes, and the second end is suspended and supported by the support and the constraint assembly, the traditional outer drum design can be omitted, and the space originally occupied by the outer drum can be used by the rotating drum, so that the volume of the rotating drum can be increased without increasing the overall volume of the laundry treatment device.

[0054] It should be noted that the laundry treatment device of the present application can be a drum washing machine, a pulsator washing machine, a dryer, a dry-wash integrated machine, or other equipment for cleaning, drying, and the like. Textile fabrics, and the following will be described by taking a drum washing machine as an example, but not limited thereto.

[0055] The technical solutions of the present application will be further described below in conjunction with the embodiments and the drawings.

[0056] Please refer to Figures 1-2 , Figure 1 is a front view of a laundry treatment device according to an embodiment of the present application, Figure 2 is Figure 1 is a cross-sectional view of the laundry treatment device shown in FIG. 1 along the line AA'.

[0057] The laundry treatment device 100 includes a cabinet 110, a driving mechanism 120, and a drum portion 130. The cabinet 110 is the outer shell of the laundry treatment device 100, which has a receiving space, and the driving mechanism 120 and the drum portion 130 are arranged inside the cabinet 110.

[0058] The box body 110 can be hexahedron-shaped or cylindrical, and generally comprises a main body part 111 provided with a first opening 111a and a cover 112 pivotally connected to the main body part 111 and rotatable relative to the main body part 111 to cover or expose the first opening 111a. After the cover 112 is opened, the user can put the clothes to be treated into the barrel part 130 through the first opening 111a.

[0059] The driving mechanism 120 can be an electric motor, for example, a direct drive motor. By using the direct drive motor, the barrel part 130 can be directly driven, and a transmission mechanism does not need to be arranged between the direct drive motor and the barrel part 130. This can not only save the internal space of the clothes treating device 100 and provide a basis for increasing the volume of the barrel part 130, but also reduce noise, wear and energy loss caused by the transmission device, prolong the service life of the clothes treating device 100 and improve the energy efficiency of the clothes treating device 100.

[0060] Please refer to Figures 3-6 , Figure 3 is a perspective structural schematic view of a barrel part according to an embodiment of the present application, Figure 4 is Figure 3 is a perspective structural schematic view of a rotating barrel shown in Figure 5 is Figure 4 is a side schematic view of a rotating barrel shown in Figure 6 is Figure 5 is a cross-sectional schematic view of a rotating barrel along the BB line shown in

[0061] In some embodiments, the barrel part 130 comprises a rotating barrel 131 having a first end 131a and a second end 131b oppositely arranged in the axial direction thereof, and the first end 131a is connected with the driving mechanism 120 to rotate under the driving of the driving mechanism 120. For example, when the driving mechanism 120 is a direct drive motor, the output shaft (rotation shaft) of the direct drive motor is fixedly connected with the first end 131a, and the rotation axis of the rotating barrel 131 coincides with the rotation axis of the output shaft. When the direct drive motor works, the output shaft drives the rotating barrel 131 to rotate coaxially with the output shaft, so as to realize the treatment of the clothes put into the interior of the rotating barrel 131.

[0062] It should be noted that, since the outer cylinder in the traditional design is omitted in the present application, the rotating cylinder 131 does not need to be provided with through holes matched with the outer cylinder. Specifically, the rotating cylinder 131 includes a first bottom wall 131c fixedly connected with the output shaft and a first side wall 131d arranged around the first bottom wall 131c, the first bottom wall 131c is located at the first end 131a, the first side wall 131d surrounds a cylindrical structure, the cylindrical structure is provided with a second opening 131e at a position opposite to the first bottom wall 131c, and the first side wall 131d is not provided with through holes penetrating through itself. In this way, it can be prevented that water and / or cleaning agent in the rotating cylinder 131 splashes to the outside of the rotating cylinder 131 during the treatment of clothes, so as to avoid the pollution, corrosion or short circuit of the internal structure or circuit of the clothes treatment device 100. At the same time, since the water and / or cleaning agent in the rotating cylinder 131 will not splash to the outside of the rotating cylinder 131, the traditional outer drum structure can be omitted, the internal space of the clothes treatment device 100 is saved, so that the size of the rotating cylinder 131 can be appropriately enlarged without increasing the volume of the cabinet 110, so as to increase the volume of the rotating cylinder 131, and thus meet the user's demand for small volume and large capacity of the clothes treatment device.

[0063] Please refer again to Figures 4-6 In some embodiments, the rotating cylinder 131 is provided with an internal flow channel (not labeled), for example, the inner side of the rotating cylinder 131 can be provided with a plurality of convex ribs 131f, the plurality of convex ribs 131f extend substantially along the axial direction of the rotating cylinder 131 and are arranged at intervals around the circumference of the rotating cylinder 131, and the inside of the convex ribs can form the internal flow channel, so that the internal flow channel can be used to discharge water and / or cleaning agent in the rotating cylinder 131. In this way, the weight distribution of the rotating cylinder 131 can be relatively balanced, the structural symmetry is good, and it is beneficial to reduce the vibration of the rotating cylinder 131 during rotation.

[0064] In some embodiments, at least part of the symmetrically arranged convex ribs 131f among the plurality of convex ribs 131f are provided in a hollow structure to form a drainage flow channel 131g, and the wall of the convex rib 131f surrounding the drainage flow channel 131g is provided with a plurality of water outlet holes 131h penetrating through itself, the plurality of water outlet holes 131h are in communication with the drainage flow channel 131g and jointly form the aforementioned internal flow channel.

[0065] Please refer to Figure 7 and Figure 8 , Figure 7 is Figure 3 a side view schematic diagram of the cylinder part shown in Figure 8 Figure 4A perspective view of the bracket shown in FIG. 13B. In some embodiments, the barrel portion 130 further comprises a bracket 132 disposed at least partially around the outer periphery of the second end 131b. The bracket 132 disposed around the outer periphery of the second end 131b can be annular and fitted around the outer periphery of the second end 131b.

[0066] That is, the laundry treating apparatus 100 disclosed herein can support the rotating drum by the bracket, thereby eliminating the need for the outer drum, and thus increasing the volume of the rotating drum without increasing the overall volume of the laundry treating apparatus 100.

[0067] In some embodiments, the bracket can be provided only at the second end of the rotating drum, i.e., to support the rotating drum at the second end thereof. Alternatively, the bracket can be provided at both the first and second ends of the rotating drum to support the first and second ends of the rotating drum. Details will be described below with reference to the accompanying drawings.

[0068] Referring to FIG. 13B, Figure 9 , Figure 9 is Figure 8 A perspective view of the first sub-bracket shown in FIG. 13B. In some embodiments, the bracket 132 can comprise a first sub-bracket 132a provided at the first end 131a to support the first end 131a. It will be understood that the first sub-bracket 132a can substantially surround the outer periphery of the first end 131a of the rotating drum 131, and the first sub-bracket 132a can be provided with a through hole for the output shaft of the driving mechanism 120 to pass through and fixedly connect the first end 131a of the rotating drum 131. The first sub-bracket 132a and the output shaft can be rotatably connected by a rotary bearing, which can be any one selected according to actual needs, and the present application does not make specific limitations.

[0069] Referring again to FIG. 13B, Figure 9 In some embodiments, the first sub-bracket 132a comprises a first main body portion 132b, a first upper portion 132c, and a first lower portion 132d. The first main body portion 132a is provided with a through hole 132e for the output shaft of the motor to pass through. The first upper portion 132c is disposed at one side of the first main body portion 132b along the height direction H of the cabinet 110, and the first lower portion 132d is disposed at the other side of the first main body portion 132b along the height direction H of the cabinet 110. The first main body portion 132b is integrally connected with the first upper portion 132c and the first lower portion 132d. In this way, the first sub-bracket 132a is of an integral structure, and the first sub-bracket 132a can be installed as an integral structure at one time when the laundry treating apparatus 100 is assembled, thereby reducing the number of components of the laundry treating apparatus 100 and simplifying the assembly process.

[0070] Referring again to FIG. 13B, Figure 9In some embodiments, the first sub-bracket 132a is provided with a first gap 132f and a second gap 132g, the first gap 132f and the second gap 132g are distributed on both sides of the first sub-bracket 132a along the width direction W of the cabinet 110, and the first gap 132f and the second gap 132g both expose at least part of the second end 131b of the rotating drum 131. In this way, the volume of the first sub-bracket 132a can be reduced, thereby saving the internal space of the clothes treatment apparatus 100 and improving the space utilization rate inside the clothes treatment apparatus 100.

[0071] It can be understood that the first upper portion 132c and the first lower portion 132d can be spaced apart along the height direction H of the cabinet 110, i.e., the first upper portion 132c and the first lower portion 132d are separated, and the gap therebetween forms the first gap 132f and the second gap 132g.

[0072] Please refer to Figure 10 , Figure 10 is Figure 8 a perspective view of the second sub-bracket. In some embodiments, the bracket 132 further includes a second sub-bracket 132h, and the second sub-bracket 132h is arranged at the second end 131b to support the second end 131b in a floating manner. The first sub-bracket 132a and the second sub-bracket 132h are oppositely arranged along the axial direction of the rotating drum 131. In this way, the support of the bracket 132 to the rotating drum 131 forms a simply supported beam type support, i.e., both ends of the rotating drum 131 can be supported, effectively improving the stability of the rotating drum 131 when rotating. Since the support of the second sub-bracket 132h to the second end 131b is a floating support, the friction between the second sub-bracket 132h and the second end 131b can be reduced, and the influence of the vibration of the rotating drum 131 on the second sub-bracket 132h can also be reduced.

[0073] Alternatively, the first sub-bracket 132a and the second sub-bracket 132h are connected to each other, for example, the first sub-bracket 132a can be fixedly connected to the second sub-bracket 132h by screws or bolts. Alternatively, the first sub-bracket 132a and the second sub-bracket 132h can be separately arranged, for example, the second sub-bracket 132h is fixed to the cabinet 110.

[0074] In order to further reduce the influence of the rotating drum 131 on the cabinet 110 when rotating, a damping structure (not shown in the figure) can be arranged between the bracket 132 and the cabinet 110. For example, the damping structure can be arranged between the first sub-bracket 132a and / or the second sub-bracket 132h and the cabinet 110. Alternatively, the damping structure can be a spring or a shock absorber. For example, when the damping structure is arranged as a spring, one end of the spring is fixedly connected to the bracket 132, and the other end of the spring is fixedly connected to the cabinet 110.

[0075] In some embodiments, the damping structure can be arranged only below the support 132, and two or more damping structures can be arranged. For example, two damping structures are arranged below the second sub-support 132h, and the two damping structures can be arranged at intervals along the width direction W of the cabinet 110 to provide two different support points for the second sub-support 132h, thereby improving stability.

[0076] Referring again to Figure 10 In some embodiments, the second sub-support 132h is provided with an avoidance hole 132i extending through the second sub-support 132h along the axial direction of the rotating drum 131, and the second sub-support 132h is sleeved on the outer periphery of the second end 131b. It can be understood that the second opening 131e is opposite to and communicates with the avoidance hole 132i, and the clothes are put into or taken out of the rotating drum 131 through the first opening 111a, the second opening 131e, and the avoidance hole 132i.

[0077] Referring again to Figure 10 In some embodiments, the second sub-support 132h includes a second main body portion 132j, a second upper portion 132k, and a second lower portion 132l. The second main body portion 132j can be provided with the avoidance hole 132i, the second upper portion 132k is arranged on one side of the second main body portion 132j along the height direction H of the cabinet 110, and the second lower portion 132l is arranged on the other side of the second main body portion 132j along the height direction H of the cabinet 110. The second main body portion 132j is connected to the second upper portion 132k and the second lower portion 132l as a whole. In this way, the second sub-support 132h is a unitary structure, and the second sub-support 132h can be installed as a unitary structure at one time when the clothes treatment apparatus 100 is assembled, thereby reducing the number of components of the clothes treatment apparatus 100 and simplifying the assembly process. It can be understood that the second sub-support 132h can be detachably connected to the first sub-support 132a through the second upper portion 132k and / or the second lower portion 132l.

[0078] In some embodiments, the second sub-support 132h is provided with a third notch 132m and a fourth notch 132n, and the third notch 132m and the fourth notch 132n are arranged on both sides of the second sub-support 132h along the width direction W of the cabinet 110. The third notch 132m and the fourth notch 132n both expose at least a portion of the second end 131b of the rotating drum 131. In this way, the volume of the second sub-support 132h can be reduced, thereby saving the internal space of the clothes treatment apparatus 100 and improving the space utilization rate of the clothes treatment apparatus 100.

[0079] It can be understood that the second upper portion 132k and the second lower portion 132l can be spaced apart along the height direction H of the cabinet 110, that is, the second upper portion 132k and the second lower portion 132l are separated, and the space between the two forms the third gap 132m and the fourth gap 132n.

[0080] Please refer to Figure 11 , Figure 11 is a schematic diagram of a front view of the cylinder portion with the counterweight structure in the embodiment of the present application.

[0081] In some embodiments, the cylinder portion 130 further comprises a first counterweight structure 133 and a second counterweight structure 134, the first counterweight structure 133 is arranged on one side of the second sub-bracket 132h along the height direction H of the cabinet 110, and the second counterweight structure 134 is arranged on the other side of the second sub-bracket 132h along the height direction H of the cabinet 110. In this way, the weight of the second sub-bracket 132h can be increased, thereby increasing its inertia, reducing the influence of the vibration of the rotating cylinder 131 on the second sub-bracket 132h, and further improving the stability of the cylinder portion 130.

[0082] Please refer to Figure 11 In some embodiments, the cylinder portion 130 further comprises a third counterweight structure 135, and the third counterweight structure 135 is arranged on the first sub-bracket 132a. In this way, the overall weight of the bracket 132 can be increased to increase the inertia of the bracket 132, thereby improving the stability of the cylinder portion 130. Secondly, the weight distribution of the bracket 132 can be optimized, avoiding the main weight of the bracket 132 being concentrated on the second sub-bracket 132h, thereby avoiding the bracket 132 from tilting.

[0083] Please refer to Figures 11-15 wherein, Figure 12 is Figure 11 is a schematic diagram of an enlarged view of the A region in Figure 13 is Figure 11 is a schematic diagram of an enlarged view of the B region in Figure 14 is a schematic diagram of a front view of the cylinder portion with the counterweight structure in the embodiment of the present application. Figure 15 is Figure 14 is a schematic diagram of an enlarged view of the C region in. In some embodiments, the laundry treating apparatus 100 realizes the floating support of the second end 131b through a constraint assembly 136 arranged between the rotating cylinder 131 and the bracket 132. Specifically, the constraint assembly 136 is configured to apply a force along the radial direction of the rotating cylinder 131 to the second end 131b, so as to make the bracket 132 floating support the second end 131b.

[0084] For example, the constraint assembly 136 is arranged between the second end 131b and the second sub-support 132h, and the second sub-support 132h is used to suspend and support the second end 131b. In this way, the rotating cylinder 131 is supported at opposite ends, which can achieve better support effect.

[0085] In some embodiments, the constraint assembly 136 includes a first sub-constraint and a second sub-constraint, the first sub-constraint is arranged at the second end 131b of the rotating cylinder 131, and the second sub-constraint is arranged at the support 132 (e.g., the second sub-support 132h). The second sub-constraint is arranged in cooperation with the first sub-constraint to apply a force along the radial direction of the rotating cylinder 131 to the first sub-constraint to suspend and support the second end 131b. In this way, the second end 131b of the rotating cylinder 131 can be non-contact supported by the support 132, which can reduce the friction between the second end 131b and the support 132 and reduce the structural wear. In addition, since the non-contact support can be considered as flexible support, the second end 131b of the rotating cylinder 131 still has a certain movement space and will not directly contact / impact the support 132, so that the influence of the vibration / oscillation of the rotating cylinder 131 on the support 132 can be reduced.

[0086] In some embodiments, the first sub-constraint and the second sub-constraint can both be magnetic structures, and the polarities of the sides of the first sub-constraint and the second sub-constraint facing each other are the same. For example, the S pole of the first sub-constraint faces the S pole of the second sub-constraint, or the N pole of the first sub-constraint faces the N pole of the second sub-constraint. In this way, the second sub-constraint can apply a repulsive force to the first sub-constraint to suspend and support the second end 131b. When the second end 131b of the rotating cylinder 131 deviates from the axis of the output shaft due to vibration, the repulsive force applied by the second sub-constraint to the first sub-constraint can drive the second end 131b to reset to a certain extent.

[0087] In still some embodiments, the first sub-constraint is an air floating surface (not shown in the figure), and the second sub-constraint is a gas jet hole (not shown in the figure). The gas jet hole sprays gas flow to the air floating surface to blow up the air floating surface and achieve air floating support.

[0088] It can be understood that the box body 110 can be provided with a gas source (not shown in the figure), such as a gas pump. The support 132 (the second sub-support 132h) is provided with an air duct (not shown in the figure). The gas pump is in communication with the air duct through an air pipe and provides gas flow to the air duct. The air duct is in communication with the gas jet hole, so that the gas flow is sprayed out of the gas jet hole to the air floating surface. The air floating surface can be the outer side of the second end 131b, or a penetration prevention plate can be arranged outside the second end 131b, and the outer side of the penetration prevention plate is used as the air floating surface.

[0089] In some embodiments, the cross section of the air floating surface in the radial direction of the rotating cylinder 131 can be set as a U shape, or a semi-circular shape, so that the air flow ejected from the air injection holes can be more effectively utilized.

[0090] It can be understood that the air injection holes are multiple, and the multiple air injection holes can be arranged on the second sub-bracket 132h in the circumferential direction of the rotating cylinder 131 and are in communication with each other inside the second sub-bracket 132h. The air floating surface is arranged around the axis of the rotating cylinder 131 outside the second end 131b.

[0091] In still other embodiments, the first sub-restricting member can be a combination of the first magnet 136a and the air floating surface, and / or the second sub-restricting member can be a combination of the second magnet 136b and the air injection hole. The specific arrangement mode thereof can be selected according to actual conditions, and will not be described here.

[0092] The present embodiment is described by taking the first sub-restricting member and the second sub-restricting member as magnetic structures.

[0093] Please refer again to Figure 11 and Figure 15 In some embodiments, the first sub-restricting member can include multiple first magnets 136a arranged on the second end 131b in the circumferential direction of the rotating cylinder 131. The second sub-restricting member can include multiple second magnets 136b arranged on the bracket 132 in the circumferential direction of the rotating cylinder 131. For example, the multiple second magnets 136b can be arranged on the second sub-bracket 132h. In this way, since the non-contact support is achieved by magnetic levitation support, and the magnetic levitation support is achieved by magnetic field interaction, in addition to the effect of the non-contact support described above, noise can be avoided between the second end 131b and the second sub-bracket 132b during the rotation of the rotating cylinder 131. Of course, as other embodiments, the first sub-restricting member can also include one magnet extending around the circumference of the rotating cylinder. Correspondingly, the second sub-restricting member can also include one magnet extending around the circumference of the second sub-bracket.

[0094] In some embodiments, the multiple first magnets 136a are arranged as a magnetic ring around the axis of the rotating cylinder 131, and the multiple second magnets 136b are arranged as a magnetic ring around the axis of the rotating cylinder 131. In this way, the multiple second magnets 136b can magnetically levitate support the multiple first magnets 136a in the entire circumferential direction of the rotating cylinder 131, so that the forces on different positions of the second end 131b in the circumferential direction are balanced, and the stability of the rotating cylinder 131 during rotation is improved.

[0095] Please refer again to Figure 12 and Figure 13In some embodiments, one side of the rotating cylinder 131 close to the support 132 is provided with a first accommodating groove 131i, and the first magnet 136a is arranged in the first accommodating groove 131i. Correspondingly, one side of the support 132 close to the rotating cylinder 131 is provided with a second accommodating groove 132o, and the second magnet 136b is arranged in the second accommodating groove 132o. In this way, the magnets can be accommodated in the accommodating grooves, avoiding the magnets protruding from the surface of the rotating cylinder 131 or the support 132, so that the first magnet 136a and the second magnet 136b can be prevented from colliding with each other and being displaced or even falling off during the rotation of the rotating cylinder 131.

[0096] For example, the first accommodating groove 131i is a plurality of first accommodating grooves 131i, and the plurality of first accommodating grooves 131i are arranged on the second end 131b along the circumferential direction of the rotating cylinder 131. The second accommodating groove 132o is a plurality of second accommodating grooves 132o, and the plurality of second accommodating grooves 132o are arranged on the second sub-support 132h along the circumferential direction of the rotating cylinder 131. The plurality of first magnets 136a are arranged in the plurality of first accommodating grooves 131i one by one in a one-to-one correspondence, and the plurality of second magnets 136b are arranged in the plurality of second accommodating grooves 132o one by one in a one-to-one correspondence.

[0097] Of course, the number of the first magnets 136a and the second magnets 136b can be the same or different, the number of the first magnets 136a and the number of the first accommodating grooves 131i can be the same or different, and the number of the second magnets 136b and the number of the second accommodating grooves 132o can be the same or different. It can be understood that the number of the first magnets 136a can be less than the number of the first accommodating grooves 131i, and the number of the second magnets 136b can be less than the number of the second accommodating grooves 132o. In addition, the shape of the first magnet 136a and the second magnet 136b is not limited, for example, it can be a cylindrical structure or a hexahedral structure.

[0098] In some embodiments, the first magnet 136a and the second magnet 136b are both permanent magnets. In this way, after the first magnet 136a and the second magnet 136b are arranged, the magnetic levitation support can be realized by using the magnetism of the permanent magnet itself. Of course, the second magnet 136b can also be arranged as an electromagnet, so that the strength of the magnetic field of the second magnet 136b can be changed by changing the current applied to the second magnet 136b, and then the support strength can be changed according to the actual vibration / oscillation of the rotating cylinder 131, which is high in flexibility.

[0099] Please refer to Figure 11 and Figure 13In some embodiments, the end surface of the second end 131b is provided with a first protruding ring 131j, which is arranged around the axis of the rotating cylinder 131, and the support 132 is provided with a second protruding ring 132p corresponding to the first protruding ring 131j, which is also arranged around the axis of the rotating cylinder 131.

[0100] For example, the second protruding ring 132p is arranged on the second main body part 132j of the second sub-support 132h, the first protruding ring 131j and the second protruding ring 132p are opposite to each other, and the second protruding ring 132p is arranged on the outer periphery of the first protruding ring 131j. At this time, the first magnet 136a is arranged on the outer periphery of the first protruding ring 131j, i.e. on the side of the first protruding ring 131j facing the second protruding ring 132p, and the second magnet 136b is arranged on the inner periphery of the second protruding ring 132p, i.e. on the side of the second protruding ring 132p facing the first protruding ring 131j.

[0101] It can be understood that the first accommodating groove 131i is arranged on the side of the first protruding ring 131j facing the second protruding ring 132p, and the opening of the first accommodating groove 131i faces the second protruding ring 132p; and the second accommodating groove 132o is arranged on the side of the second protruding ring 132p facing the first protruding ring 131j, and the opening of the second accommodating groove 132o faces the first protruding ring 131j.
