[0049] It should be noted that, without conflict, the embodiments in the present application and the technical features in the embodiments can be combined with each other. The detailed description in the specific implementation manners should be understood as an explanatory illustration of the gist of the present application and should not be regarded as an improper limitation to the present application.

[0050] In the description of the embodiments of the present application, the orientation or positional relationship of "upper", "lower", and "height direction" is based on the orientation or positional relationship when the laundry treatment device is in normal use. For example, as shown in the attached Figure 3 orientation or positional relationship, it should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0051] On the one hand, an embodiment of the present application provides a lid 11 for a laundry treatment device. Please refer to Figures 1 to 8 , a laundry input channel 11a is provided in the middle area of the lid 11, and laundry is put in or taken out through the laundry input channel 11a. The lid 11 forms a plurality of independent water injection cavities 11b, and each water injection cavity 11b is formed with a water injection port and a water spraying port. The water spraying ports of each water injection cavity 11b are all located at the bottom side of the lid 11 to spray water to the inner drum balancing device 14 located below the lid 11.

[0052] The lid 11 can supply water to the inner drum balancing device 14 of the cylinder assembly. Exemplarily, an embodiment of the present application also provides a cylinder assembly. Please refer to Figures 1 to 3 , the cylinder assembly includes an outer tub 12, an inner drum 13 rotatably disposed in the outer tub 12, an inner drum balancing device 14 connected to the inner drum 13, and the lid 11 in any embodiment of the present application. The inner drum balancing device 14 includes an annular balancing member 141 surrounding the top side of the inner drum 13. The annular balancing member 141 is formed with a plurality of independent annular water inlet ports 141a. Each annular water inlet port 141a surrounds the top end of the annular balancing member 141. That is to say, the annular water inlet ports 141a are arranged in sequence along the radial direction of the annular balancing member 141, and the plurality of annular water inlet ports 141a are concentrically distributed, and the annular water inlet ports 141a are not communicated with each other. The lid 11 is disposed at the top end of the outer tub 12. The lid 11 is used to cover the gap between the outer tub 12 and the inner drum 13. The lid 11 is located above the annular balancing member 141, and the top end of the annular water inlet port 141a is open to receive the liquid from at least one water spraying port.

[0053] In the barrel assembly provided by the embodiment of the present application, water enters the water injection cavity 11b through the water injection port, and then flows out from the water spray port. The water flowing out from the water spray port enters the annular water inlet 141a. The inner barrel balancing device 14 is arranged roughly coaxially with the inner barrel 13. During the rotation of the inner barrel 13, the inner barrel balancing device 14 will rotate together with the inner barrel 13, while the barrel cover 11 will not rotate with the inner barrel 13. Multiple annular water inlets 141a are distributed in concentric circles. During the washing or dehydration process, the inner barrel 13 continues to rotate, and the annular water inlet 141a can continuously receive the water flow from the water spray port. Therefore, the process of the water spray port injecting water into the annular water inlet 141a will not be affected by the rotation of the inner barrel 13. The water injection cavity 11b, the water injection port and the water spray port are formed on the barrel cover 11, and the barrel cover 11 is fully utilized to supply water to the inner barrel balancing device 14, which can not only save the limited space in the clothing processing equipment, but also reduce product components, simplify the manufacturing process, and reduce costs.

[0054] The specific arrangement of the water injection port and the water spray port is not limited. For example, in one embodiment, please refer to Figure 4 and Figure 5 In the top projection of the barrel cover 11, the barrel cover 11 is in a circular ring shape, and multiple water injection ports are arranged along the circumference of the barrel cover 11. In this way, the water inlet pipe used to supply water to the water injection port can be arranged along the circumference of the barrel cover 11, which is convenient for simplifying the pipeline arrangement of the water inlet pipe and avoiding mutual interference between the water inlet pipes. Multiple water spray ports are arranged along the radial direction of the barrel cover 11, and the direction of the water flow out of the water spray ports is toward the annular water inlet 141a. In this way, the water flow out of the water spray ports is prevented from touching the inner wall surface of the annular water inlet 141a, causing the water to splash out of the annular water inlet 141a.

[0055] In one embodiment, please refer to Figures 4 to 6 ,as well as Figure 10 The barrel cover 11 includes an annular cover body 111 formed with a clothing delivery channel 11a, a plurality of water injection pipes 112 connected to the annular cover body 111, at least one partition rib, a water injection shell 113, and a plurality of water spray pipes 114 connected to the water injection shell 113. The inner space of the water injection pipe 112 is a water injection port, the inner space of the water spray pipe 114 is a water spray port, and the water injection shell 113 (see Figure 10 ) A partial area of ​​the bottom side of the annular cover body 111 is detachably covered to form a water injection space, and partition ribs are arranged in the water injection space to divide the water injection space into a plurality of water injection chambers 11b. In this way, the water injection shell 113 is easy to load and unload.

[0056] There is no limitation on the detachable connection method between the water injection shell 113 and the annular cover body 111. Exemplarily, the water injection shell 113 and the annular cover body 111 include but are not limited to snap connection, threaded connection, screw connection or bolt connection, etc.

[0057] In another embodiment, the water injection shell 113 and the annular cover body 111 are an integrally formed structure.

[0058] It should be noted that the number of partition ribs can be one or more.

[0059] In one embodiment, please refer to Figure 5 , in the top view projection of the bucket lid 11, the water injection pipe 112 is within the projection range of the annular lid body 111. Exemplarily, the laundry treatment device includes an outer box body with a door panel provided on the top side, a cylinder assembly is located inside the outer box body, and the door panel can be opened or closed to pick up and place clothes from the washing cavity of the inner cylinder 13. The space inside the outer box body is limited. In the top view projection of the bucket lid 11, the water injection pipe 112 is within the projection range of the annular lid body 111, which can prevent the water injection pipe 112 from increasing the size of the bucket lid 11 in its radial direction. Thus, the original assembly gap between the bucket lid 11 and the outer box body is avoided from being changed.

[0060] In order to further prevent the water spray pipe 114 from increasing the size of the bucket lid 11 in its radial direction, in one embodiment, please refer to Figure 5 and Figure 6 , in the top view projection of the bucket lid 11, the water spray pipe 114 is within the projection range of the annular lid body 111. Thus, the original assembly gap between the bucket lid 11 and the outer box body of the laundry treatment device is further avoided from being changed.

[0061] The water injection pipe 112 is located above the water spray pipe 114. In one embodiment, please refer to Figure 4 , the water injection pipe 112 does not exceed the top surface of the annular lid body 111. Designed in this way, it is avoided that the water injection pipe 112 increases the size of the bucket lid 11 in the up and down direction, and the original assembly gap between the bucket lid 11, the annular balance member 141 and the door panel is avoided from being changed.

[0062] In order to prevent the water spray pipe 114 from increasing the size of the bucket lid 11 in the up and down direction, in one embodiment, please refer to Figure 4 , the water spray pipe 114 does not exceed the bottom surface of the annular lid body 111. Thus, it is further avoided that the water injection pipe 112 increases the size of the bucket lid 11 in the up and down direction, and the original assembly gap between the bucket lid 11, the annular balance member 141 and the inner cylinder 13 is avoided from being changed.

[0063] In one embodiment, please refer to Figure 5 , the annular lid body 111 and the water injection pipe 112 are of an integrally formed structure. Thus, the production process of the annular lid body 111 and the water injection pipe 112 can be simplified, and the production cost can be reduced. Exemplarily, the annular lid body 111 and the water injection pipe 112 are integrally injection molded.

[0064] In order to further simplify the production process of the water injection shell 113 and the water spray pipe 114 and reduce the cost, in one embodiment, please refer to Figure 9, the water injection shell 113 and the water spray pipe 114 are of an integrally formed structure. Exemplarily, the water injection shell 113 and the water spray pipe 114 are integrally injection molded.

[0065] In one embodiment, please refer to Figure 4 and Figure 5 , a partial area of the annular cover body 111 protrudes towards the top side to form a top cover 1111. The space inside the top cover 1111 is part of the water injection cavity 11b. In this way, the shape of the annular cover body 111 is changed to a lesser extent to increase the volume of the water injection cavity 11b. Each water injection pipe 112 is connected to one side of the top cover 1111 along the radial direction of the bucket cover 11 outward, so as to facilitate the arrangement of the water inlet pipe. The water injection shell 113 is hermetically covered around the bottom side of the top cover 1111, so as to prevent water leakage at the joint between the water injection shell 113 and the top cover 1111.

[0066] The sealing method between the water injection shell 113 and the top cover 1111 is not limited. For example, the joint between the water injection shell 113 and the top cover 1111 can be bonded with waterproof glue, or a sealing structure such as a sealing ring can be provided at the joint between the water injection shell 113 and the top cover 1111.

[0067] In one embodiment, please refer to Figures 7 to 10 , the partition ribs include a first sub-partition rib 1151 provided on the end face of the top cover 1111 facing the water injection shell 113, and a second sub-partition rib 1152 provided on the end face of the water injection shell 113 facing the top cover 1111. A limiting groove 1151a that opens towards the water injection shell 113 is formed on the first sub-partition rib 1151. The second sub-partition rib 1152 is inserted into the limiting groove 1151a through the open part of the limiting groove 1151a to divide the water injection space into a plurality of water injection cavities 11b. The insertion of the second sub-partition rib 1152 into the limiting groove 1151a not only facilitates the positioning and assembly of the water injection shell 113 onto the top cover 1111, but also prevents the water liquid in adjacent two water injection cavities 11b from flowing through.

[0068] In another embodiment, a positioning groove that opens towards the top cover 1111 is formed on the second sub-partition rib 1152. The first sub-partition rib 1151 is inserted into the positioning groove through the open part of the positioning groove to divide the water injection space into a plurality of water injection cavities 11b. This also facilitates the positioning and assembly of the water injection shell 113 onto the top cover 1111, and prevents the water liquid in adjacent two water injection cavities 11b from flowing through.

[0069] In order to further simplify the production process, in one embodiment, please refer to Figure 8 , the first sub-partition rib 1151 and the top cover 1111 are of an integrally formed structure. The second sub-partition rib 1152 and the water injection shell 113 are of an integrally formed structure.

[0070] The specific structural shape of the water injection shell 113 is not limited. Exemplarily, in one embodiment, please refer to Figures 9 to 11, the water injection shell 113 includes a bottom plate 1131 and a surrounding rib 1132 surrounding the bottom plate 1131. The space jointly enclosed by the bottom plate 1131 and the surrounding rib 1132 is part of the water injection space. A part of the bottom plate 1131 protrudes towards the bottom side to form a plurality of water outlet parts 11311. The partition rib extends into the water outlet part 11311 to divide the space in the water outlet part 11311 into a plurality of water outlet cavities 11311a that are radially spaced along the annular cover body 111. The water outlet cavity 11311a is part of the water injection cavity 11b, that is to say, the water outlet cavities 11311a are independent of each other. A plurality of spray pipes 114 are distributed radially along the annular cover body 111, and the spray pipes 114 are communicated with the water outlet cavities 11311a. The surrounding rib 1132 hermetically covers a partial area on the bottom side of the annular cover body 111. The bottom plate 1131, the surrounding rib 1132 and a partial area on the bottom side of the annular cover body 111 jointly enclose to form a water injection space. Without significantly increasing the overall size of the water injection shell 113, the water outlet part 11311 can not only increase the volume of the water injection cavity 11b, but also facilitate the end of the spray pipe 114 to be close to the annular water inlet 141a, thereby further avoiding the water flow splashing ejected from the water spray port.

[0071] In a specific embodiment, please refer to Figures 8 to 11 , the surrounding rib 1132 hermetically covers the periphery of the top cover 1111. The bottom plate 1131, the surrounding rib 1132 and the top cover 1111 jointly enclose to form a water injection space. Specifically, the second sub-partition rib 1152 is arranged on the end surface of the bottom plate 1131 facing the top cover 1111. The second sub-partition rib 1152 extends into the water outlet part 11311 to divide the space in the water outlet part 11311 into a plurality of water outlet cavities 11311a that are radially spaced along the annular cover body 111. Since the space between the bottom plate 1131 and the top cover 1111 is large and the water outlet cavity 11311a is small, a shape that is large at the top and small at the bottom is formed, so that the water flow in the water injection cavity 11b can enter the annular water inlet 141a more quickly.

[0072] In an embodiment, please refer to Figure 10 , in the cross-section of the spray pipe 114, the spray pipe 114 includes a circular sub-channel 114a and a plurality of arc-shaped sub-channels 114b that are circumferentially spaced along the circular sub-channel 114a. Each arc-shaped sub-channel 114b is communicated with the circular sub-channel 114a. Designed in this way, the water flow flowing out from the water spray port is generally columnar instead of conical divergent, which plays a role in gathering the water flow and further avoiding water flow splashing.

[0073] In an embodiment, please refer to Figure 3 and Figure 16, the inner cylinder balancing device 14 includes a water storage balancing member 142 disposed below the annular balancing member 141, that is to say, the position of the annular balancing member 141 is higher than that of the water storage balancing member 142. The annular balancing member 141 is formed with a plurality of mutually independent water storage cavities 141b, and the water storage cavities 141b communicate with at least one annular water inlet 141a, that is, the water liquid in any two annular water inlets 141a does not flow through each other, and the water liquid in any two water storage cavities 141b does not flow through each other either. A plurality of water storage balancing members 142 are distributed at intervals along the circumferential direction of the annular balancing member 141, and the water storage balancing member 142 communicates with at least one water storage cavity 141b, that is, the water in the water storage cavity 141b can flow into the water storage balancing member 142 under the action of gravity.

[0074] During the dehydration stage, the inner cylinder 13 starts to rotate at a low speed and can be accelerated to a high speed within a short time. For example, it rotates at 800 - 1200 revolutions per minute, and uses a large centrifugal force at high speed to dehydrate the clothes. When the rotational speed of the inner cylinder 13 is relatively low, the centrifugal force received by the water liquid is very small. Therefore, the water liquid can enter the annular balancing member 141 from the annular water inlet 141a relatively smoothly. Under the action of its own gravity, the water liquid will enter the water storage balancing member 142 from the annular balancing member 141. That is, in the low-speed stage, the amount of water in the annular balancing member 141 is very small, and most of it enters the water storage balancing member 142 to resist the load eccentric mass of the inner cylinder 13 together with the injected water volume and the overall mass of the water storage balancing member 142. That is, in the low-speed stage, the balance adjustment mainly relies on the water storage balancing member 142. When the rotational speed of the inner cylinder 13 increases, if the inner cylinder 13 has a load eccentricity, at a relatively high rotational speed of the inner cylinder 13, the centrifugal force of the water liquid in the annular balancing member 141 is relatively large, and the water liquid remains in the water storage cavity 141b and is thrown on the inner side wall of the water storage cavity 141b. It is not easy for the water liquid to enter the water storage balancing member 142. Therefore, in the high-speed stage, the inner cylinder 13 can rely on the annular balancing member 141 to play a better balance adjustment role. It should be noted that if a certain amount of water liquid has been stored in the water storage balancing member 142 in the low-speed stage, then in the high-speed stage, the water storage balancing member 142 can also play a certain balance adjustment role with the mass of the stored water liquid. Therefore, in the low-speed stage, the cylinder assembly can perform balance adjustment through the water storage balancing member 142, and in the high-speed stage, the cylinder assembly can perform balance adjustment through the annular balancing member 141. That is to say, in the full rotational speed range of the inner cylinder 13, it can play a good balancing role for the inner cylinder 13, effectively reducing the risk of barrel collision and reducing vibration noise, and improving the user experience.

[0075] In one embodiment, please refer to Figure 3 and Figure 14, a plurality of water storage chambers 141b are circumferentially distributed along the circumference of the annular balance member 141. It can be understood that the plurality of water storage chambers 141b should be distributed as evenly as possible to better perform balance adjustment. For example, in the embodiment of the present application, taking the number of water storage chambers 141b as 3 as an example, the central angle corresponding to each water storage chamber 141b is approximately 120°.

[0076] In one embodiment, please refer to Figure 14 and Figure 15 , at least a part of the water storage chamber 141b is located on the outer periphery of the annular water inlet 141a that is radially outermost along the annular balance member 141. An inlet 141b' communicating with the annular water inlet 141a is formed on the side wall of the water storage chamber 141b along the radially inner side of the annular balance member 141. An outlet 141b'' communicating with the water storage balance member 142 is formed on the bottom wall of the water storage chamber 141b; in the top view projection of the cylindrical body assembly, at least a part of the outlet 141b'' is located on the radially inner side of the inlet 141b' along the annular balance member 141.

[0077] When the rotational speed of the inner cylinder 13 is relatively low, the centrifugal force received by the liquid is very small. Therefore, the liquid can smoothly enter the water storage chamber 141b from the inlet 141b', and then enter the water storage balance member 142 from the outlet 141b''. When the rotational speed of the inner cylinder 13 is relatively high, the liquid in the annular water inlet 141a quickly enters the water storage chamber 141b through the inlet 141b' under the action of a large centrifugal force. The liquid moves away from the inner side of the annular balance member 141 under the action of the centrifugal force. Therefore, it is difficult for the liquid to flow to the outlet 141b'', so that most of the liquid remains in the water storage chamber 141b, further restricting the liquid from entering the water storage balance member 142. Therefore, at the high-speed stage, the inner cylinder 13 can better rely on the annular balance member 141 to perform balance adjustment.

[0078] In another embodiment, the inlet 141b' is arranged on the bottom wall of the annular water inlet 141a. When the rotational speed of the inner cylinder 13 is relatively low, the centrifugal force received by the liquid is very small, which is convenient for the liquid in the annular water inlet 141a to quickly enter the water storage chamber 141b through the inlet 141b'.

[0079] The specific structural form of the water storage chamber 141b is not limited. In one embodiment, please refer to Figure 14 and Figure 15, a part of the water storage cavity 141b is located on the outer periphery of the annular water inlet 141a which is radially outermost along the annular balance member 141, and another part of the water storage cavity 141b extends below the annular water inlet 141a which is radially innermost along the annular balance member 141. The water outlet 141b" is arranged below the annular water inlet 141a which is radially innermost along the annular balance member 141. This makes the water outlet 141b" as close as possible to the radially inner side of the annular balance member 141. In the high-speed stage of the inner cylinder 13, it is more difficult for the water liquid to flow to the water outlet 141b", so that most of the water liquid remains in the water storage cavity 141b, further restricting the water liquid from entering the water storage and balance member 142.

[0080] The specific structural shape of the annular balance member 141 is not limited. Exemplarily, in one embodiment, please refer to Figures 12 to 14 , the annular balance member 141 includes an annular housing 1411, annular vertical plates 1412, annular enclosing plates 1413, annular transverse plates 1414 and partition plates. The annular housing 1411 has an annular cavity. The annular enclosing plates 1413 are vertically arranged between the two side walls of the annular cavity. The annular transverse plates 1414 are horizontally arranged in the annular cavity. The two ends of the annular transverse plates 1414 along the radial direction of the annular housing 1411 are respectively connected to the side wall of the annular cavity close to the center of the annular housing 1411 and the annular enclosing plates 1413. The annular transverse plates 1414 and the annular enclosing plates 1413 together divide the annular cavity into a water inlet area and a water storage area, and the top side of the water inlet area is open. A plurality of annular vertical plates 1412 are sequentially arranged at intervals along the radial direction of the annular housing 1411 in the water inlet area to divide the water inlet area into a plurality of annular water inlets 141a. A plurality of partition plates are arranged at intervals along the circumferential direction of the annular housing 1411 in the water storage area to divide the water storage area into a plurality of water storage cavities 141b, and the plurality of water storage cavities 141b are arranged along the circumferential direction of the annular housing 1411. In this way, the appearance of the annular balance member 141 is generally circular. It can not only reduce the design difficulty, has a simple structure, makes full use of the space in the annular housing 1411, makes the structure of the annular balance member 141 compact, is convenient for production and manufacturing, but also is convenient for the water liquid to be thrown on the inner wall surface of the annular housing 1411 under the action of centrifugal force.

[0081] In one embodiment, please refer to Figure 14 and Figure 15, on the upper surface of the annular transverse plate 1414, a plurality of stepped surfaces are formed, which are distributed along the height direction of the annular housing 1411. The heights of the plurality of stepped surfaces increase sequentially from the inside to the outside along the radial direction of the annular housing 1411, that is, the height of the stepped surface located on the radially outer side of the annular housing 1411 is higher than that of the stepped surface located on the radially inner side of the annular housing 1411. An annular longitudinal plate 1412 is arranged on each stepped surface. At least one water inlet 141b' is formed in the part of the annular transverse plate 1414 located between two adjacent stepped surfaces. The water inlet 141b' communicates the water-containing cavity 141b with the corresponding annular water inlet 141a. In this way, it is not only convenient to open the water inlet 141b' along the radial direction of the annular housing 1411. When the rotational speed of the inner cylinder 13 is relatively large, the water liquid in the annular water inlet 141a can quickly enter the water-containing cavity 141b through the water inlet 141b' under the action of a large centrifugal force, but also can prevent the water liquid in the annular water inlet 141a from entering the adjacent annular water inlet 141a through the water inlet 141b'.

[0082] In one embodiment, please refer to Figure 14 and Figure 15 , on the bottom plate 1131 of the annular housing 1411, a water outlet 141b'' is formed. In the top view projection of the cylindrical body assembly, at least part of the water outlet 141b'' is located on the radially inner side of the water inlet 141b' along the annular balancing member 141. When the rotational speed of the inner cylinder 13 is relatively large, the water liquid moves away from the inner side of the annular housing 1411 under the action of centrifugal force. Therefore, it is difficult for the water liquid to flow to the water outlet 141b'', so that most of the water liquid remains in the water-containing cavity 141b, further restricting the water liquid from entering the water storage and balancing member 142. Therefore, in the high-speed stage, the inner cylinder 13 can better play the role of balance adjustment by relying on the annular balancing member 141.

[0083] In one embodiment, please refer to Figure 14 and Figure 15 , the annular balancing member 141 includes at least one water baffle 1415 arranged in the water-containing cavity 141b. Each water baffle 1415 divides the water-containing cavity 141b into a plurality of connected sub-water-containing cavities 141b, and the plurality of sub-water-containing cavities 141b are distributed along the circumferential direction of the annular balancing member 141. Specifically, the water baffle 1415 is located in the space surrounded by two side walls of the annular housing 1411 along its radial direction, the annular transverse plate 1414, and the annular enclosing plate 1413. On the one hand, the water baffle 1415 can not only make the water flow distribution in the water-containing cavity 141b relatively uniform, but also drive the water flow to rotate together; on the other hand, the water baffle 1415 can also play a role in strengthening the structural strength of the annular balancing member 141.

[0084] The setting of the water baffle 1415 needs to ensure that the water in each sub-water-containing cavity 141b can flow. For example, please refer to Figure 14 and Figure 15, in one embodiment, at least one notch 1415a is provided on the radially outer side of the water baffle 1415 along the annular balance member 141, and adjacent two sub-water storage cavities 141b communicate with each other through the notch 1415a. When the inner cylinder 13 rotates at a high speed, the water liquid in the water storage cavity 141b is distributed on the inner side wall of the water storage cavity 141b under the action of centrifugal force, and the water flow between adjacent two sub-water storage cavities 141b can flow through the notch 1415a along the inner side wall of the water storage cavity 141b and then circulate. For another example, please refer to Figure 14 , in one embodiment, there is a spaced space 1415b between the bottom surface of the water baffle 1415 and the bottom wall of the water storage cavity 141b, and adjacent two sub-water storage cavities 141b communicate with each other through the spaced space 1415b. In this embodiment, when the inner cylinder 13 rotates at a low speed, the water flow in adjacent two sub-water storage cavities 141b circulates through the spaced space 1415b.

[0085] It can be understood that, in some embodiments, only the above-mentioned notch 1415a may be provided, in other embodiments, only the above-mentioned spaced space 1415b may be provided, and in still other embodiments, both the notch 1415a and the spaced space 1415b are provided.

[0086] In one embodiment, please refer to Figure 12 , the annular balance member 141 includes at least one reinforcing rib 1416 disposed in the annular water inlet 141a, and the reinforcing rib 1416 connects two inner side walls of the annular water inlet 141a along the radial direction of the annular balance member 141. The reinforcing rib 1416 can strengthen the structural strength of the annular balance member 141 at the annular water inlet 141a. In addition, the reinforcing rib 1416 does not completely block the space in the annular water inlet 141a to ensure that the annular water inlet 141a can continuously receive water flow.

[0087] It should be noted that one or more reinforcing ribs 1416 can be provided in any one or more annular water inlets 141a.

[0088] The specific structural shape of the reinforcing rib 1416 is not limited, for example, sheet-like, strip-like, etc.

[0089] The specific position of the water storage balance member 142 is not limited. Exemplarily, in one embodiment, please refer to Figure 1 , the water storage balance member 142 is located on the inner side of the inner cylinder 13 along its radial direction, that is, the water storage balance member 142 is disposed inside the inner cylinder 13. In this way, the water storage balance member 142 does not occupy the narrow installation space between the inner cylinder 13 and the outer barrel 12, and therefore does not increase the risk of the inner cylinder 13 hitting the barrel. In another embodiment, the water storage balance members 142 are all located on the outer side of the inner cylinder 13 along its radial direction, that is, the water storage balance members 142 can all be disposed between the circumferential outer surface of the inner cylinder 13 and the circumferential inner surface of the outer barrel 12.

[0090] In one embodiment, please refer to Figure 3 , Figure 12 and Figure 13 , the inner cylinder balancing device 14 includes water guiding members 144 provided corresponding to the water storage balancing members one by one. The water guiding members 144 are connected between the annular housing 1411 and the water storage balancing members 142. The water guiding members 144 include a water passing portion 1441 and a housing portion 1442. The top of the water passing portion 1441 is connected to the bottom of the annular housing 1411 and extends along the circumferential direction of the annular housing 1411. A water passing port 1441a is provided on the inner side of the water passing portion 1441 along the radial direction of the annular housing 1411. The bottom of the water passing portion 1441 is open to communicate with the water storage balancing member 142. The housing portion 1442 covers around the water outlet 141b, and the top of the housing portion 1442 is open to receive the water liquid from the water containing cavity 141b. The water liquid in the water containing cavity 141b enters the housing portion 1442 from the top of the housing portion 1442, and the water liquid in the housing portion 1442 enters the water passing portion 1441 through the water passing port 1441a. The housing portion 1442 is used to guide the water liquid in the water containing cavity 141b to the water passing portion 1441, which is convenient for reducing the size of the water passing portion 1441 along the radial direction of the annular housing 1411. For example, when the water guiding member 144 is located in the inner cylinder 13, the water guiding member 144 can fit the inner cylinder 13 to avoid occupying too much space inside the inner cylinder 13.

[0091] In some embodiments, the annular balancing member 141 and the water guiding member 144 are integrally formed. In this way, it is convenient to simplify the process of the annular balancing member 141 and the water guiding member 144 and reduce the manufacturing cost.

[0092] The assembly method between the water storage balancing member 142 and the water guiding member 144 is not limited. Exemplarily, in one embodiment, please refer to Figure 3 , the top end of the water storage balancing member 142 and the bottom end of the water passing portion 1441 are hermetically inserted and matched. In this way, it is not only convenient to quickly position and install the water storage balancing member 142 on the water passing portion 1441, but also convenient for the water liquid to quickly enter the water storage balancing member 142 to avoid the water liquid flowing out from the connection between the water storage balancing member 142 and the water passing portion 1441.

[0093] The sealing method between the top end of the water storage balancing member 142 and the bottom end of the water passing portion 1441 is not limited. For example, the connection between the top end of the water storage balancing member 142 and the bottom end of the water passing portion 1441 can be bonded with waterproof glue, or a sealing structure such as a sealing ring can be provided.

[0094] The specific position of the water guiding member 144 is not limited. Exemplarily, in one embodiment, please refer to Figure 1, both the water guide member 144 and the water storage and balance member 142 are located on the inner side of the inner cylinder 13 along its radial direction, that is, both the water guide member 144 and the water storage and balance member 142 can be arranged inside the inner cylinder 13. In this way, the water guide member 144 and the water storage and balance member 142 do not occupy the narrow installation space between the inner cylinder 13 and the outer barrel 12. Therefore, the risk of the inner cylinder 13 hitting the barrel is not increased. In another embodiment, both the water guide member 144 and the water storage and balance member 142 are located on the outer side of the inner cylinder 13 along its radial direction, that is, both the water guide member 144 and the water storage and balance member 142 can be arranged between the circumferential outer surface of the inner cylinder 13 and the circumferential inner surface of the outer barrel 12.

[0095] In one embodiment, please refer to Figure 3 , the water storage and balance member 142 is formed with a water storage cavity 142a and a drainage channel 142b located below the water storage cavity 142a. The bottom wall of the water storage cavity 142a is communicated with the drainage channel 142b, and the top end of the water storage and balance member 142 is open to receive the water liquid from the water containing cavity 141b. The water liquid enters the water storage cavity 142a through the top end of the water storage and balance member 142, and the water liquid in the water storage cavity 142a and the overall mass of the water storage and balance member 142 jointly resist the load eccentric mass of the inner cylinder 13. The drainage channel 142b is used to drain the water liquid in the water storage and balance member 142. That is to say, when the balance adjustment function is completed or when it is necessary to drain the water liquid in the water storage cavity 142a for other reasons, the water liquid can be drained out of the water storage and balance member 142 under the action of its own gravity through the drainage channel 142b.

[0096] The drainage channel 142b is used to drain the water liquid in the water storage and balance member 142. That is to say, the water liquid entering the water storage cavity 142a will be drained out through the drainage channel 142b and will not be stored in the water storage cavity 142a for a long time. In some embodiments, the drainage channel 142b can be always in an open state. In other embodiments, the drainage channel 142b can be selectively opened or closed. For example, during the washing stage, the drainage channel 142b can be kept closed to prevent the washing water from flowing back into the water storage cavity 142a through the drainage channel 142b. Before the start of the dehydration stage, the drainage channel 142b is in an open state so that there is basically no water in the water storage cavity 142a before the start of dehydration. During the dehydration process, the drainage channel 142b is in a closed state so that the water can be stored in the water storage cavity 142a. When the dehydration is over, the drainage channel 142b is in an open state to drain the water in the inner cylinder balance device 14.

[0097] The method for selectively opening or closing the drainage channel 142b is not limited. In one embodiment, please refer to Figure 2 and Figure 3, the cylinder assembly includes a float 15, which can selectively open or close the drainage channel 142b under the combined action of its own gravity and the buoyancy of the liquid. During the washing process, the float 15 overcomes its own gravity under the buoyancy of the liquid to block the drainage channel 142b, and the drainage channel 142b is closed; when the water level drops, the float 15 can drop under its own gravity until it disengages from the drainage channel 142b, and the drainage channel 142b is opened.

[0098] In some embodiments, please refer to Figure 1 , the inner cylinder 13 includes a cylinder body 131 and a cylinder bottom 132 provided at the lower end of the cylinder body 131. The cylinder body 131 is wound from a metal plate. The cylinder bottom 132 can be made of plastic material or other materials. It can be understood that the cylinder bottom 132 is not a closed structure. Exemplarily, when the laundry treatment device is a pulsator washing machine, a relatively large mounting hole is provided in the middle of the cylinder bottom 132, and the pulsator of the laundry treatment device is provided at the mounting hole.

[0099] The specific structure of the water storage and balance member 142 is not limited. In one embodiment, please refer to Figure 3 and Figure 16 , the water storage and balance member 142 includes a water tank 1421 and a drain pipe 1422 provided at the lower end of the water tank 1421. The space inside the water tank 1421 is a water storage cavity 142a, and the space inside the drain pipe 1422 is a drainage channel 142b. A plurality of limiting cavities 13a communicating with the outer tub 12 are formed on the cylinder bottom 132 of the inner cylinder 13. The bottom end of each drain pipe 1422 extends into a corresponding limiting cavity 13a, and the float 15 is floatingly arranged in the limiting cavity 13a to block or open the bottom end of the drain pipe 1422. The drain pipe 1422 rotates synchronously with the inner cylinder 13. In this way, the drain pipe 1422 and the limiting cavity 13a remain relatively stationary, so as to facilitate the float 15 to block or open the bottom end of the drain pipe 1422 during the rotation of the inner cylinder 13. The drain pipe 1422 extends into the limiting cavity 13a to prevent the float 15 from disengaging from the limiting cavity 13a. The formation of the limiting cavity 13a on the cylinder bottom 132 of the inner cylinder 13 simplifies the structure of the cylinder assembly and reduces the design difficulty.

[0100] The manner in which the limiting cavity 13a communicates with the outer tub 12 is not limited. In one embodiment, please refer to Figure 3 , the top end of the limiting cavity 13a has an opening, the bottom end of the drain pipe 1422 extends into the limiting cavity 13a through the opening, and at least one communication port is formed on the circumferential surface of the limiting cavity 13a, and the communication port communicates the limiting cavity 13a with the outer tub 12. In this way, the limiting cavity 13a communicates with the atmosphere, and the liquid in the outer tub 12 can enter the limiting cavity 13a through the communication port, so that the float 15 can float in the limiting cavity 13a under the action of buoyancy and gravity.

[0101] The specific structure of the float 15 is not limited. Exemplarily, in one embodiment, please refer toFigure 2 and Figure 3 The float 15 is spherical. In the top view projection of the cylinder assembly, the projection pattern of the limiting cavity 13a is circular. Specifically, the diameter of the projection pattern of the limiting cavity 13a is greater than the diameter of the float 15, so as to prevent the limiting cavity 13a from interfering with the up-and-down floating of the float 15; the diameter of the float 15 is greater than the inner diameter of the bottom end of the drain pipe 1422, so that the float 15 can block the bottom end of the drain pipe 1422.

[0102] It can be understood that the diameter of the projection pattern of the limiting cavity 13a can be slightly greater than the diameter of the float 15. In this way, the limiting cavity 13a will not interfere with the up-and-down floating of the float 15, and the float 15 is prevented from shaking radially along the seat body. The diameter of the float 15 is slightly greater than the inner diameter of the drain pipe 1422 to avoid excessive sizes of the float 15 and the seat body and occupying unnecessary space.

[0103] The specific structure of the limiting cavity 13a is not limited. For example, in one embodiment, please refer to Figure 3 , the cylinder has a cylindrical structure, and the space inside the cylindrical structure is the limiting cavity 13a, and at least one communication port is formed on the circumferential surface of the cylindrical structure. The drain pipe 1422 is a straight pipe with a uniform inner diameter.

[0104] In one embodiment, please refer to Figure 2 , a plurality of water tanks 1421 are evenly distributed along the circumference of the inner cylinder 13. Thus, it is convenient to balance and adjust the load eccentricity that occurs during the rotation of the inner cylinder 13.

[0105] In one embodiment, please refer to Figure 1 and Figure 2 , the cylinder assembly includes a connecting member. The connecting member sequentially penetrates through the circumferential side wall of the inner cylinder 13 and the side wall of the water tank 1421 close to the inner surface of the inner cylinder 13 along the outer side in the radial direction of the inner cylinder 13 to fix the water tank 1421 to the inner cylinder 13. Using the connecting member to fix the water tank 1421 to the cylinder body 131, on the one hand, the connection between the water tank 1421 and the inner cylinder 13 is strengthened by the connecting member, and on the other hand, since the connecting member sequentially penetrates through the circumferential side wall of the inner cylinder 13 and the side wall of the water tank 1421 close to the inner surface of the inner cylinder 13 along the outer side in the radial direction of the inner cylinder 13, the clothes in the washing cavity of the inner cylinder 13 can be prevented from wearing the connecting member.

[0106] The specific structural shape of the connecting member is not limited. For example, the connecting member is a screw. A stud is provided in the water tank 1421. The screw sequentially penetrates through the circumferential side wall of the inner cylinder 13 and the side wall of the water tank 1421 close to the inner surface of the inner cylinder 13 from the outer side in the radial direction of the inner cylinder 13 and is screwed into the stud. In this way, it is convenient to load and unload the water tank 1421.

[0107] In another embodiment, the water tank 1421 can also be welded to the inner cylinder 13. Thus, it can also play a role in preventing the water tank 1421 from loosening.

[0108] In one embodiment, please refer to Figure 13 and Figure 16 , in the top view projection of the cylinder assembly, both the water tank 1421 and the water passing part 1441 are in a fan-shaped arc concentric with the inner cylinder 13. In this way, it is convenient for the top end of the water tank 1421 and the bottom end of the water passing part 1441 to be hermetically plugged. The radially outer surface of the water tank 1421 along the annular housing 1411 and the radially outer surface of the water passing part 1441 along the annular housing 1411 are both attached to the inner surface of the inner cylinder 13. Thus, it is convenient to arrange the water tank 1421 and the water passing part 1441 to reduce the space occupied by the water tank 1421 and the water passing part 1441 inside the inner cylinder 13.

[0109] In one embodiment, please refer to Figure 4 , Figure 5 , Figures 12 to 15 , the bucket cover 11 is provided with a downwardly bent lower bent part 116 at the inner end along its radial inner side; the inner cylinder balancing device 14 includes an annular anti-hooking plate 143 surrounding the radially inner surface of the annular balancing member 141, and the annular anti-hooking plate 143 extends obliquely upward in a direction away from the annular balancing member 141; in the top view projection of the cylinder assembly, the edge line of the annular anti-hooking plate 143 along the radially inner side of the annular balancing member 141 overlaps with the edge line of the lower bent part 116. The upper part of the annular anti-hooking plate 143 and the lower bent part 116 are substantially in the same arc surface. In this way, when taking clothes from the washing cavity of the inner cylinder 13, the clothes are prevented from being hooked to the lower bent part 116, resulting in damage to the clothes and / or the bucket cover 11.

[0110] It should be noted that there is a gap between the annular anti-hooking plate 143 and the lower bent part 116 to prevent the lower bent part 116 from interfering with the rotation of the annular anti-hooking plate 143 along with the inner cylinder 13. Further, the closer the top end of the annular anti-hooking plate 143 is to the lower bent part 116, the smaller the gap between the top end of the annular anti-hooking plate 143 and the lower bent part 116 is better, which can better prevent the clothes from being hooked to the lower bent part 116.

[0111] In the embodiment of the present application, the material of the inner cylinder balancing device 14 is not limited. Exemplarily, the inner cylinder balancing device 14 is made of plastic.

[0112] On the other hand, the embodiment of the present application provides a laundry treatment device, which includes the cylinder assembly, the electromagnetic valve and the control device in any embodiment of the present application; the electromagnetic valve can selectively conduct or cut off the upstream water path of the water injection port, and the control device is used to control the opening or closing of the electromagnetic valve.

[0113] Exemplarily, when the solenoid valve is in the open state, the upstream water path of the water injection port is connected, and water can enter the water injection port through the upstream water path to supply water to the annular balance member 141; when the solenoid valve is in the closed state, the upstream water path of the water injection port is cut off, and water cannot enter the water injection port through the upstream water path, thereby stopping the water supply to the annular balance member 141.

[0114] The specific type of the clothes processing device is not limited, for example, the clothes processing device can be an integration of any one or more of a washing machine, a washing machine, and a shoe washing machine. No limitation is made here.

[0115] The rotation axis of the inner drum 13 may be along the vertical direction, for example, a pulsator washing machine; the rotation axis of the inner drum 13 may also be inclined at a certain angle relative to the vertical direction, for example, an agitator washing machine.

[0116] In the washing stage, the inner drum 13 rotates at a very low speed, for example, at 40 revolutions per minute, and rotates intermittently, so there is no need to perform balance adjustment, that is, in the washing stage, there is no need to inject water into the annular balance member 141. Before the dehydration stage begins, there is basically no water in the inner drum balancing device 14, so that it is convenient to inject water according to the load eccentricity information of the inner drum 13 in the dehydration stage.

[0117] In the clothing processing device of the embodiment of the present application, when the inner drum 13 has load eccentricity, the control device can control the solenoid valve to open to inject water into the corresponding annular water inlet 141a, and the inner drum balancing device 14 can play a good active balancing role, effectively reduce the risk of hitting the drum and reduce vibration noise, thereby improving the user experience.

[0118] It should be noted that the control device can control the solenoid valve to inject water into only one of the annular water inlets 141a at a time, or can control the solenoid valve to inject water into multiple annular water inlets 141a at the same time. In the embodiment of the present application, multiple means at least two, for example, two, three or more.

[0119] It is understandable that the control device needs to determine the annular water inlet 141a to be filled with water and the amount of water according to the load eccentricity information of the inner drum 13. The laundry processing device can obtain the load eccentricity information in a manner already known in the prior art, which will not be described in detail here.

[0120] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0121] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
