[0043] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be fully conveyed to those skilled in the art.

[0044] It should be understood that the terms used herein are only for the purpose of describing specific exemplary embodiments and are not intended to be limiting.

[0047] As Figures 1 to 10 shown, according to an embodiment of the present application, an embodiment of the present invention provides a laundry treatment drum 100, which can be applied to a laundry treatment device.

[0048] As Figure 1 and Figure 2 shown, the laundry treatment drum 100 includes a housing member 200, a filter member, and a movable assembly 400. The housing member 200 is disposed within the laundry treatment drum 100. The housing member 200 has a first opening 220 and a second opening 230. The first opening 220 faces the interior of the laundry treatment drum 100 and communicates with the laundry treatment drum 100. The second opening 230 faces away from the laundry treatment drum 100 and communicates with the outside of the laundry treatment drum 100. The filter member is disposed in the housing member 200 and is adapted to filter impurities entering the housing member 200 so that the impurities are contained within the housing member 200. The movable assembly 400 is disposed at the second opening 230, and the movable assembly 400 is capable of moving so that the impurities contained within the housing member 200 enter the outside of the laundry treatment drum 100 through the position of the second opening 230.

[0049] The laundry treatment drum 100 can be the inner drum of a laundry treatment device. A laundry treatment chamber 110 is provided inside the laundry treatment drum 100. The laundry treatment device generally further includes an outer drum, and for the sake of easy description, the outer drum is defined as the second cylinder 600. The second cylinder 600 (i.e., the outer drum) is sleeved on the outer periphery of the laundry treatment drum 100 (i.e., the inner drum) and is spaced apart from each other. The laundry treatment drum 100 can rotate relative to the second cylinder 600 about its own axis. A discharge port 610 is provided on the second cylinder 600. The discharge port 610 communicates with the second cylinder 600. A control valve is provided on the discharge port 610. The opening or closing of the discharge port 610 can be controlled through the control valve. When the discharge port 610 is open, the laundry treatment device can drain water outwards; when the discharge port 610 is closed, the cleaning water can be temporarily stored inside the laundry treatment device to perform operations such as washing on the laundry treatment device.

[0050] The laundry treatment chamber 110 refers to the accommodation chamber formed inside the laundry treatment drum 100. The external water flow refers to the water flow outside the laundry treatment drum 100, and more specifically, the water flow between the laundry treatment drum 100 and the second cylinder 600. The internal water flow refers to the water flow inside the laundry treatment drum 100, that is, the water flow from the laundry treatment chamber 110.

[0051] The receiving member 200 is connected to the laundry treatment drum 100 and is located inside the laundry treatment chamber 110. The receiving member 200 forms a receiving cavity 210, and both the first opening 220 and the second opening 230 communicate with the receiving cavity 210.

[0052] The filter element is used to filter debris such as lint in the water flow so that the debris such as lint is received in the receiving cavity 210 of the receiving member 200. The filter element can be provided inside the receiving cavity 210 and is located between the first opening 220 and the second opening 230. Specifically, the filter element can be configured as a filter net, and the filter net can be fixed to the receiving member 200 by means such as pasting and is provided corresponding to the first opening 220. The filter element should be able to ensure the normal passage of water flow, but debris such as lint is intercepted and remains in the receiving cavity 210.

[0053] The movable component 400 is arranged to be movable at the second opening 230, and it can be used to control the opening or closing of the second opening 230. That is to say, the movable component 400 can close the second opening 230 or can also make the second opening 230 conductive. When the second opening 230 is closed, basically no or only a small amount of water flow can flow through the position corresponding to the second opening 230, that is, the movable component 400 cuts off between the outside of the laundry treatment drum 100 and the laundry treatment chamber 110. When the movable component 400 makes the second opening 230 conductive, the water flow can be made to conduct unidirectionally.

[0054] In this embodiment, the laundry treatment drum can collect lint during the laundry treatment process in the receiving member 200 through the cooperation of the receiving member 200 and the filter member thereon; through the movement of the movable component 400, the impurities received in the receiving member 200 can enter the outside of the laundry treatment drum 100 through the position of the second opening 230. In this way, the collection and cleaning of sundries can be completed during the laundry treatment process of the laundry treatment device, improving the convenience of the collection and cleaning operations of sundries. Moreover, the collection and discharge of sundries can be realized by relying on the flowing action of water, without disassembling the receiving member, reducing the labor intensity of the user, and the collection and discharge of sundries are relatively convenient.

[0055] In some embodiments of the present application, as Figures 2 to 4 shown, the movable component 400 includes a first one-way conduction member 410, and the first one-way conduction member 410 is disposed at the second opening 230 for controlling the closing or one-way conduction of the second opening 230.

[0056] The first one-way conduction member 410 can move toward the inner side of the laundry treatment drum 100 to make the second opening 230 conduct unidirectionally, or the first one-way conduction member 410 can move toward the outer side of the laundry treatment drum 100 to make the second opening 230 conduct unidirectionally. In order to improve the one-way conduction ability of the first one-way conduction member 410, generally, the first one-way conduction member 410 can only move toward one of the inner side and the outer side of the laundry treatment drum 100. In the case where only the first one-way conduction member 410 is provided and the second one-way conduction member 420 is not provided, after the first one-way conduction member 410 moves, it should be able to make the impurities in the receiving member 200 enter the outside of the laundry treatment drum 100.

[0057] In some embodiments, the movable component 400 can have a first state and a second state, and the movable component 400 can switch between the first state and the second state. In the first state, the movable component 400 is adapted to external water flow to flow into the receiving cavity 210 from the second opening 230, so that the external water flow flows through the filter member and then flows from the first opening 220 to the laundry treatment cavity 110. In the second state, the movable component 400 is adapted to internal water flow to flow out of the receiving cavity 210 from the second opening 230, so that the internal water flow flows through the first opening 220, the filter member, and the second opening 230 to the outside of the laundry treatment drum 100.

[0058] The movable component 400 can further include a third state of closing the second opening 230. The movable component 400 can be a multi-way movable component, which realizes the switching between the first state and the second state by switching different conduction ports. The movable component 400 can also adopt other structures.

[0059] During the process of the laundry treating device treating laundry, sundries such as hair and lint on the laundry can enter the water in the laundry treating chamber 110. The water with sundries can enter between the laundry treating drum 100 and the second cylinder 600, thus serving as external water flow. When the movable assembly 400 is in the first state, the external water flow flows into the receiving chamber 210, and after being filtered by the filter element, it flows back into the laundry treating chamber 110 of the laundry treating drum 100. The filter element can filter the sundries in the water flow passing through it, so that the sundries are intercepted in the receiving member 200. When the movable assembly 400 is in the second state, the sundries intercepted by the filter element are separated from the filter element and can enter the outside of the laundry treating drum 100 through the second opening 230. The internal water flow flows through the filter element from the first opening 220 and flows towards the second opening 230, and then can discharge the sundries from the outside of the laundry treating drum 100 (i.e., between the laundry treating drum 100 and the second cylinder 600). Among them, the process of the sundry receiving chamber 210 moving to the outside of the laundry treating drum 100 through the second opening 230 can be carried out by being carried under the impact of the internal water flow, or can be realized by other acting forces on the sundries. For example, when the second opening 230 is opened, the sundries can move out of the second opening 230 under the action of centrifugal force.

[0060] It can be understood that during the process of the laundry treating device needing to collect sundries, the movable assembly 400 can be in the first state. At this time, the discharge port 610 can be in the closed state; during the process of the laundry treating device needing to clean sundries, the movable assembly 400 can be in the second state. At this time, the discharge port 610 can be in the open state, so that the sundries can directly discharge from the discharge port 610 after passing through the outside of the laundry treating drum 100. During the operation of the laundry treating device, the movable assembly 400 can be in the first state during the laundry washing stage and in the second state during the laundry dehydration stage.

[0061] According to the laundry treating drum of this embodiment, as Figure 3 shown, in the first state, the movable assembly 400 is adapted for the external water flow to flow into the receiving chamber 210 from the second opening 230. In this way, the external water flow can flow into the receiving chamber 210 from the outside of the laundry treating drum 100, and after filtering sundries such as lint through the filter element, it flows into the laundry treating chamber 110 from the first opening 220. The sundries such as lint in the water flow are collected in the receiving chamber 210 under the filtering action of the filter element. As Figure 4As shown, in the second state, the movable component 400 is adapted to allow the internal water flow to flow out of the receiving cavity 210 from the second opening 230. In this way, debris can flow from the second opening 230 to the outside of the laundry processing drum 100, and the internal water flow can flow into the receiving cavity 210 from the laundry processing cavity 110 via the first opening 220 and the filter element, and then be discharged via the second opening 230. The debris collected in the receiving cavity 210 can flow to the outside of the laundry processing drum 100 and be discharged under the driving action of the water flow. By switching the movable component 400 between the first state and the second state, the collection and cleaning of debris can be completed during the process of processing laundry, improving the convenience of the debris collection and cleaning operations. Moreover, the collection and discharge of debris can be achieved by relying on the flowing action of the water flow, without disassembling the receiving member 200, reducing the labor intensity of the user, and making the collection and discharge of debris more convenient.

[0062] The following presents a structure that can achieve the switching of the movable component 400 between the first state and the second state.

[0063] Referring to Figures 2 to 7 As shown, the movable component 400 may further include a second one-way conduction member 420. A communication hole 415 is provided on the first one-way conduction member 410. The second one-way conduction member 420 is connected to the first one-way conduction member 410 and is provided corresponding to the communication hole 415. The second one-way conduction member 420 is used to control the closing or one-way conduction of the communication hole 415, and the conduction direction of the first one-way conduction member 410 is opposite to that of the second one-way conduction member 420.

[0064] One of the first one-way conduction member 410 and the second one-way conduction member 420 is one-way conductive in the first state, and the other is one-way conductive in the second state.

[0065] It can be understood that the communication hole 415 communicates the two sides of the first one-way conduction member 410. When the communication hole 415 is conductive, it is actually equivalent to the second opening 230 being conductive. The conduction direction of the first one-way conduction member 410 can be understood as the water flow direction flowing through the second opening 230 when the first one-way conduction member 410 makes the second opening 230 conductive. The conduction direction of the second one-way conduction member 420 can be understood as the conduction direction of the flowing through the flow hole when the second one-way conduction member 420 makes the communication hole 415 conductive.

[0066] In one implementation, the first one-way conduction member 410 conducts in one direction in the first state, and the second one-way conduction member 420 conducts in one direction in the capillary cleaning state. Specifically, the one-way conduction of the first one-way conduction member 410 is that the first one-way conduction member 410 makes the second opening 230 conductive, so that the external water flow outside the laundry treatment cylinder 100 can flow into the accommodation cavity 210 through the second opening 230, and after being filtered by the filter member, it flows to the laundry treatment cavity 110 of the laundry treatment cylinder 100. The one-way conduction of the second one-way conduction member 420 is that the second one-way conduction member 420 makes the communication hole 415 conductive, so that the internal water flow in the laundry treatment cavity 110 of the laundry treatment cylinder 100 can flow into the accommodation cavity 210 through the filter member, and flows to the outside of the laundry treatment cylinder 100 through the communication hole 415.

[0067] In another implementation, the second one-way conduction member 420 conducts in one direction in the first state, and the first one-way conduction member 410 conducts in one direction in the capillary cleaning state. Specifically, the one-way conduction of the second one-way conduction member 420 is that the second one-way conduction member 420 makes the communication hole 415 conductive, and enables the external water flow outside the laundry treatment cylinder 100 to flow into the accommodation cavity 210 through the communication hole 415, and after being filtered by the filter member, it flows to the laundry treatment cavity 110 of the laundry treatment cylinder 100. The one-way conduction of the first one-way conduction member 410 is that the first one-way conduction member 410 makes the second opening 230 conductive, so that the internal water flow in the laundry treatment cavity 110 of the laundry treatment cylinder 100 can flow into the accommodation cavity 210 through the filter member, and flows to the outside of the laundry treatment cylinder 100 through the communication hole 415.

[0068] The first one-way conduction member 410 can be movably connected to the housing member 200. Specifically, the first one-way conduction member 410 can be installed on the housing member 200 so as to be able to slide linearly. The first one-way conduction member 410 can open or close the second opening 230 by sliding; the first one-way conduction member 410 can also be rotatably installed on the housing member 200, and the first one-way conduction member 410 opens or closes the second opening 230 by rotating. Among them, the linear movement or rotation of the first one-way conduction member 410 can be driven independently by a power member. For example, a motor can be used in cooperation with a transmission member to drive the first one-way conduction member 410 to move or rotate; the linear movement or rotation of the first one-way conduction member 410 can also be achieved by relying on the power member combined with the water flow force, centrifugal force, etc. generated during the operation of the laundry treatment device.

[0069] The second one-way conduction member 420 can be movably connected to the first one-way conduction member 410. Specifically, the second one-way conduction member 420 can be installed on the first one-way conduction member 410 to be able to linearly slide. The second one-way conduction member 420 can open or close the communication hole 415 on the first one-way conduction member 410 through sliding; the second one-way conduction member 420 can also be rotatably installed on the first one-way conduction member 410, and the second one-way conduction member 420 can open or close the communication hole 415 on the first one-way conduction member 410 through rotation. Among them, the linear movement or rotation of the second one-way conduction member 420 can be driven separately by a power member. For example, a motor can be used in cooperation with a transmission member to drive the second one-way conduction member 420 to move or rotate; the linear movement or rotation of the second one-way conduction member 420 can also be achieved by relying on the power member combined with the water flow force, centrifugal force, etc. generated during the operation of the laundry treatment device.

[0070] It should also be noted that the first one-way conduction member 410 can be integrally movably arranged or partially movably arranged. For example, the first one-way conduction member 410 is a flexible member such as a rubber sheet. One end of the first one-way conduction member 410 can be fixedly connected to the receiving member 200, and the other end can be movably arranged. The second opening 230 is opened or closed by the movement or rotation of the movable part. The second one-way conduction member 420 can be integrally movably arranged or partially movably arranged. For example, the second one-way conduction member 420 is a flexible member such as a rubber sheet. One end of the second one-way conduction member 420 can be fixedly connected to the receiving member 200, and the other end can be movably arranged. The communication hole 415 is opened or closed by the movement or rotation of the movable part.

[0071] Optionally, in some embodiments, among the first one-way conduction member 410 and the second one-way conduction member 420, one of them is configured to conduct under the impact of external water flow, and the other is configured to conduct unidirectionally under the centrifugal force when the laundry treatment drum 100 is at a preset rotational speed.

[0072] Specifically, when the first one-way conduction member 410 is used to conduct in the first state, the second one-way conduction member 420 is used to conduct unidirectionally in the second state. At this time, the first one-way conduction member 410 can be adapted to be impacted by the external water flow outside the laundry drum 100 to make the second opening 230 conduct unidirectionally, and the external water flow can flow into the receiving cavity 210 through the second opening 230; the second one-way conduction member 420 can be adapted to make the communication hole 415 conduct under the action of centrifugal force, and the internal water flow and sundries can flow out of the receiving cavity 210 through the communication hole 415, where the centrifugal force is the centrifugal force generated during the rotation of the laundry drum 100 at a preset speed. When the second one-way conduction member 420 is used to conduct in the first state, the first one-way conduction member 410 is used to conduct unidirectionally in the second state. At this time, the second one-way conduction member 420 can be adapted to be impacted by the external water flow outside the laundry drum 100 to make the communication hole 415 conduct unidirectionally, and the external water flow can flow into the receiving cavity 210 through the communication hole 415; the first one-way conduction member 410 can be adapted to make the second opening 230 conduct under the action of centrifugal force, and the internal water flow and sundries can flow out of the receiving cavity 210 through the second opening 230, and the centrifugal force is the centrifugal force generated during the rotation of the laundry drum 100 at a preset speed.

[0073] The preset speed is the speed of the laundry drum 100 during the sundries cleaning process, and this preset speed is usually greater than the maximum rotation speed of the laundry drum 100 during the lint collection process. Specifically, the preset speed can be the speed of the laundry treatment device in the laundry dehydration stage, and this preset speed is greater than the maximum speed of the laundry drum 100 in the laundry washing stage.

[0074] It should be noted that as Figure 4 shown, when the first one-way conduction member 410 makes the second opening 230 conduct unidirectionally, the second one-way conduction member 420 is usually in a state of closing the communication hole 415; as Figure 3 shown, when the second one-way conduction member 420 makes the communication hole 415 conduct unidirectionally, the first one-way conduction member 410 is usually in a state of closing the second opening 230. As Figure 2 shown, when neither the first one-way conduction member 410 nor the second one-way conduction member 420 is affected by the impact of the external water flow, and the laundry drum 100 does not rotate (or the rotation speed is lower than the preset speed), the first one-way conduction member 410 is usually in a state of closing the second opening 230, and the second one-way conduction member 420 is usually in a state of closing the communication hole 415.

[0075] In the state where the first one-way conduction member 410 closes the second opening 230 in this embodiment, it can be maintained by the driving member 412 of the first one-way conduction member 410. Specifically, in one embodiment, the first one-way conduction member 410 includes a driving member 412 and a baffle 411. The baffle 411 is rotatably connected to the receiving member 200, and the driving member 412 is connected to the baffle 411.

[0076] Among them, the driving member 412 is used to make the baffle 411 close the second opening 230. The baffle 411 can rotate toward one of the inner side and the outer side of the receiving member under the action of an external force, so as to conduct the second opening 230.

[0077] For the convenience of description, the external force that makes the baffle 411 rotate is defined as the first acting force. The first acting force can be the impact force of external water flow or the centrifugal force when the laundry treatment drum 100 is at a preset rotational speed. That is to say, the baffle 411 can rotate under the impact of external water flow or under the centrifugal force when the laundry treatment drum 100 is at a preset rotational speed.

[0078] The baffle 411 can be a plate member that is generally a flat plate. One side surface 202 of the baffle 411 can face the receiving cavity 210 of the receiving member 200, and the other side surface of the baffle 411 can face the outside of the receiving member 200, which is also the outside of the laundry treatment drum 100. The communication hole 415 can be provided on the baffle 411 and penetrate through the opposite two side surfaces of the baffle 411.

[0079] It can be understood that the driving member 412 should be able to apply a force to the baffle 411 so that the baffle 411 can maintain the state of closing the second opening 230. At the same time, when the baffle 411 is in the state of conducting the second opening 230, after the corresponding external force is withdrawn, the driving member 412 should also have the ability to reset the baffle 411 to the state of closing the second opening 230. When the first one-way conduction member 410 is applicable to the first state to make the second opening 230 conduct unidirectionally, when the baffle 411 is impacted by external water flow, it should be able to overcome the acting force of the driving member 412 and make the baffle 411 rotate, thereby making the second opening 230 conduct unidirectionally; when the first one-way conduction member 410 is applicable to the second state to make the second opening 230 conduct unidirectionally, when the baffle 411 is acted upon by a certain intensity of centrifugal force, it should be able to overcome the acting force of the driving member 412 and make the baffle 411 rotate, thereby making the second opening 230 conduct unidirectionally.

[0080] To prevent the baffle 411 from rotating in the reverse direction so that the baffle 411 can control the unidirectional conduction of the second opening 230, such as Figures 2 to 4As shown, a stopper 240 is provided on the receiving member 200. The baffle 411 is located on one side of the stopper 240, and in a state where the baffle 411 closes the first opening 220, the baffle 411 abuts against the stopper 240.

[0081] In a specific embodiment, as Figures 2 to 4 shown, the baffle 411 has opposite first and second ends. The first end is rotatably connected to the receiving member 200, and the second end is disposed on one side of the stopper 240 and can abut against the side surface of the stopper 240 facing the second end. The baffle 411 can rotate around the first end to move the second end closer to or away from the stopper 240.

[0082] The stopper 240 can be a stop block, and the stop block can be fixedly connected to the receiving member 200. The stopper 240 can limit the movement of the baffle 411 so that the baffle 411 realizes unidirectional conduction.

[0083] Specifically, in a manner where the first one-way conduction member 410 is applicable to the first state to unidirectionally conduct the second opening 230, and the baffle 411 is applicable to be impacted by external water flow to unidirectionally conduct the second opening 230, the stopper 240 is provided on the side of the baffle 411 facing the outside of the laundry treatment drum 100, and the stopper 240 restricts the movement of the second end of the baffle 411 towards the outside of the laundry treatment drum 100. That is to say, under the restriction of the stopper 240, the second end of the baffle 411 can only move inside the stopper 240 (the side facing the laundry treatment chamber 110). During use, when the baffle 411 abuts against the stopper 240, the second opening 230 is closed. When the baffle 411 is impacted by external water flow, the second end of the baffle 411 can move inward to conduct the second opening 230. When the baffle 411 is subjected to an outward acting force, such as a relatively high centrifugal force, due to the restriction of the stopper 240, the baffle 411 always remains in contact with the stopper 240 and cannot conduct the second opening 230.

[0084] As Figures 2 to 4 shown, in a manner where the first one-way conduction member 410 is applicable to the second state to unidirectionally conduct the second opening 230, and the baffle 411 unidirectionally conducts the second opening 230 under the action of a certain strength of centrifugal force, the stopper 240 is provided on the side of the baffle 411 facing the inside of the laundry treatment drum 100 (that is, facing the laundry treatment chamber 110), and the stopper 240 restricts the movement of the second end of the baffle 411 towards the inside of the laundry treatment drum 100. That is to say, under the restriction of the stopper 240, the second end of the baffle 411 can only move outside the stopper 240 (the side facing the laundry treatment chamber 110). During use, as Figure 4As shown, when the baffle 411 abuts against the stopper 240, the second opening 230 is closed. When the baffle 411 is under the action of a certain strength of centrifugal force, the second end of the baffle 411 can move outwards to conduct the second opening 230. When the baffle 411 is subjected to an inward acting force, such as the impact of external water flow, due to the limitation of the stopper 240, the baffle 411 always remains in contact with the stopper 240 and cannot conduct the second opening 230.

[0085] In some embodiments, the driving member 412 can be an elastic structure. The driving member 412 has a resilience force, and the resilience force drives the baffle 411 to have a tendency to close the second opening 230.

[0086] The driving member 412 can rely on the elastic force generated by its own deformation to close the second opening 230 by the baffle 411. The driving member 412 can be a spring, a spring sheet, or a rubber block and other components that can undergo elastic deformation. When the baffle 411 is in the state of closing the second opening 230, the driving member 412 can be in a natural state or in a slightly deformed state, and apply a force to the baffle 411 to maintain the baffle 411 in the state of closing the second opening 230; when the baffle 411 moves to conduct the second opening 230, the driving member 412 will deform and accumulate elastic potential energy, so that the baffle 411 has a tendency to reset to close the second opening 230.

[0087] Optionally, as Figure 6 and Figure 7 shown, in one implementation, the driving member 412 includes a torsion spring 413, and the torsion spring 413 is connected between the baffle 411 and the receiving member 200.

[0088] The torsion spring 413 includes a main body portion and two torsion arms. The main body portion is spirally arranged to form a mounting hole. One end of the main body portion is fixedly connected to one of the torsion arms, and the other end of the main body portion is fixedly connected to the other torsion arm.

[0089] In a specific embodiment, as Figures 2 to 4 、 Figure 6 and Figure 7 shown, the first one-way conduction member 410 further includes a connecting shaft 414. The baffle 411 is connected to the receiving member 200 through the connecting shaft 414. The connecting shaft 414 is rotatably connected to the receiving member 200 and fixedly connected to the baffle 411. The torsion spring 413 is sleeved on the connecting shaft 414 through the mounting hole. The two torsion arms of the torsion spring 413 are connected to the receiving member 200. The baffle 411 and the connecting shaft 414 can rotate together around the axis of the connecting shaft 414 to make the second opening 230 conduct unidirectionally. When the baffle 411 moves to conduct the second opening 230, the rotation of the baffle 411 and the connecting shaft 414 causes the torsion spring 413 to deform, so that the torsion spring 413 accumulates elastic potential energy.

[0090] Among them, connection holes can be provided on the baffle 411, and the connection shaft 414 can pass through and be fixed in the connection holes. The torsion spring 413 and the connection shaft 414 can be fixedly arranged. Specifically, the connection shaft 414 can pass through the installation hole and be fixedly arranged with an interference fit with the main body part of the torsion spring 413. As Figure 6 and Figure 7 shown, positioning members 217 are respectively arranged on both sides of the torsion spring 413 of the receiving member 200, and the two torsion arms are respectively connected to the corresponding positioning members 217 to be connected to the receiving member 200 through the positioning members 217.

[0091] It should be noted that the arrangement of the torsion spring 413 is not limited to the above-given manner. For example, the main body part can be installed on the receiving member 200 through a fixed shaft, and the two torsion arms are respectively connected to the receiving member 200 and the baffle 411. When the baffle 411 conducts the second opening 230, the torsion spring can be deformed to store elastic potential energy.

[0092] It should also be noted that the reset of the baffle 411 or maintaining the state of closing the second opening 230 may not be limited to relying on the form of the driving member 412. That is to say, the first one-way conduction member 410 may not be provided with the driving member 412. For example, the baffle 411 can rely on its own characteristics to maintain or reset to the state of closing the second opening 230. Specifically, the first one-way conduction member 410 can be a flexible elastic member with bending ability, such as a rubber pad. The rubber pad closes the second opening 230 in the natural state. In this way, after the rubber pad is unidirectionally conducted by the action of centrifugal force or water flow impact, it can be reset to close the second opening 230 under the action of its own elastic restoring force. The state in which the second one-way conduction member 420 closes the communication hole 415 in this embodiment can be maintained by the second one-way conduction member 420 through a driving member 412, such as a torsion spring 413, or the second one-way conduction member 420 can rely on its own structural characteristics to maintain. For example, the second one-way conduction member 420 can be a flexible rubber pad. The rubber pad closes the communication hole 415 in the natural state. In this way, after the rubber pad is unidirectionally conducted by the action of centrifugal force or water flow impact, it can be reset to close the communication hole 415 under the action of its own elastic restoring force.

[0093] In some embodiments, such as Figures 2 to 4 , and in combination with Figure 5As shown, the communication hole 415 is provided on the baffle 411. The second one-way conduction member 420 includes a valve sheet 421. The valve sheet 421 is connected to the baffle 411 and covers the communication hole 415. Specifically, one end of the valve sheet 421 may be fixedly connected to the baffle 411, and the other end of the valve sheet 421 is located on one side of the baffle 411 and abuts against the baffle 411. The end of the valve sheet 421 that abuts against the baffle 411 can move relative to the baffle 411 to control the opening or closing of the communication hole 415.

[0094] For the convenience of description, the end of the valve sheet 421 fixedly connected to the baffle 411 is defined as the first end portion, and the side of the valve sheet 421 that abuts against the baffle 411 is defined as the second end portion. When the second end portion of the valve sheet 421 abuts against the baffle 411, the communication hole 415 is closed; the second end portion of the valve sheet 421 can move toward the other side of the inner side and the outer side of the receiving member under the action of an external force, so that the communication hole 415 is conducted.

[0095] For the convenience of description, the external force that causes the valve sheet 421 to move is defined as the second acting force. The second acting force may be the impact force of external water flow or the centrifugal force when the laundry treatment drum 100 is at a preset rotational speed. That is to say, the baffle 411 can rotate under the impact of external water flow or under the action of the centrifugal force when the laundry treatment drum 100 is at a preset rotational speed.

[0096] It should be noted that, under the impact of the external water flow, one of the second opening 230 and the connecting hole 415 is connected, that is, under the impact of the external water flow, one of the baffle 411 and the valve plate 421 can be moved; when the laundry treatment drum 100 is under the centrifugal force of the preset speed, the other of the second opening 230 and the connecting hole 415 is connected, that is, under the impact of the external water flow, the other of the baffle 411 and the valve plate 421 can be moved. That is, when the baffle 411 and the valve plate 421 are set, they can be configured as follows: the baffle 411 rotates under the impact of the external water flow, and the valve plate 421 moves and opens the connecting hole 415 under the centrifugal force of the laundry treatment drum 100 at the preset speed, or the baffle 411 rotates under the centrifugal force of the laundry treatment drum 100 at the preset speed, and the valve plate 421 moves and opens the connecting hole 415 under the impact of the external water flow. The baffle 411 and the valve plate 421 are configured such that the baffle 411 rotates under the impact of the external water flow, and when the valve plate 421 moves and opens the connecting hole 415 under the centrifugal force of the laundry treatment drum 100 at a preset speed, the valve plate 421 is arranged on the side of the baffle 411 facing the accommodating chamber 210, that is, the inner side of the baffle 411, and the baffle 411 limits the outward movement of the valve plate 421. During use, when the valve plate 421 abuts against the baffle 411, the connecting hole 415 is closed. When the valve plate 421 is impacted by the external water flow, the second end of the valve plate 421 can move inward to open the connecting hole 415. When the valve plate 421 is subjected to an outward force, such as a high centrifugal force, due to the limitation of the baffle 411, the valve plate 421 always keeps abutting against the baffle 411, and cannot open the second opening 230. Figures 2 to 4 As shown, the baffle 411 and the valve plate 421 are configured so that when the baffle 411 rotates under the centrifugal force of the clothes processing drum 100 at a preset speed, and the valve plate 421 moves under the impact of the external water flow and opens the connecting hole 415, the valve plate 421 is arranged on the side of the baffle 411 away from the accommodating chamber 210, that is, the outer side of the baffle 411, and the baffle 411 limits the inward movement of the valve plate 421. During use, when the valve plate 421 abuts against the baffle 411, the connecting hole 415 is closed. When the valve plate 421 is subjected to a centrifugal force of a certain strength, the second end of the valve plate 421 can move outward to make the connecting hole 415 conductive. When the valve plate 421 is subjected to an inward force, such as the impact of the external water flow, due to the limitation of the valve plate 421, the valve plate 421 always keeps abutting against the baffle 411 and cannot make the connecting hole 415 conductive.

[0097] In some embodiments, the valve plate 421 is a flexible sheet-like member, the first end of the valve plate 421 is fixedly connected to the baffle 411, and the other end of the valve plate 421 is set as a free end. In the natural state, the second end of the valve plate 421 abuts against the baffle 411 and seals the connecting hole 415. Under the impact of external water flow or the centrifugal force of a certain intensity generated by the clothing treatment drum 100, the valve plate 421 can be deformed and elastically bent, so that the connecting hole 415 is conductive. Among them, one end of the valve plate 421 can be connected to the baffle 411 by means of snap connection, bonding, etc. In a specific embodiment, Figure 2 and Figure 5 As shown, the baffle 411 is provided with a slot 416 corresponding to the first end of the valve plate 421 , and the first end of the valve plate 421 is provided with a protrusion 422 , which is locked in the slot 416 to fix the first end of the valve plate 421 to the baffle 411 .

[0098] The valve plate 421 may be a sheet-like member with elasticity and flexibility, such as a silicone sheet, a rubber sheet, or soft plastic. The baffle 411 may be provided with a limiting boss 417 at the circumferential edge of one side where the valve plate 421 is provided, and the valve plate 421 is provided on the inner side of the limiting boss 417 .

[0099] Optionally, in some implementations, the second end of the valve plate 421 can be connected to the first end of the baffle 411, and the first end of the valve plate 421 abuts against the second end of the baffle 411, so that the valve plate 421 and the baffle 411 are unidirectionally conductive from different directions respectively.

[0100] In a specific embodiment, Figures 2 to 4 As shown, the baffle 411 and the valve plate 421 are configured such that the baffle 411 rotates under the centrifugal force of the laundry treatment drum 100 at a preset speed, and the valve plate 421 moves under the impact of the external water flow and opens the connecting hole 415. In this embodiment, a limiting boss 417 protrudes inwardly from the circumferential edge of the baffle 411, and the valve plate 421 is arranged on the inner side of the limiting boss 417. A clamping groove 416 is arranged on the side of the baffle 411 facing the receiving cavity 210, and a clamping protrusion 422 is arranged on the first end of the valve plate 421, and the clamping protrusion 422 is clamped in the clamping groove 416. The second end of the valve plate 421 is used to abut against the side of the baffle 411 facing the receiving cavity 210 to seal the connecting hole 415.

[0101] In some embodiments, a through opening 120 is provided on the clothing treatment drum 100, and the second opening 230 of the containing member 200 corresponds to and is connected to the through opening 120. The clothing treatment drum 100 is provided with a guide member 500 at the through opening 120, and the guide member 500 is used to guide the external water flow outside the clothing treatment drum 100 to the through opening 120.

[0102] When there is water flow outside the clothing treatment drum 100, the guide member 500 can make the external water flow outside the clothing treatment drum 100 flow toward the through-port 120, which is conducive to more external water flow entering the receiving cavity 210. In this way, the filter element can filter more water flow, which is conducive to improving the collection effect of debris such as hair and improving the cleanliness of clothing treatment.

[0103] Specifically, the flow guide 500 may include a scraper 510, which is arranged obliquely along the radial direction of the laundry treatment drum 100. The scraper 510 may be provided on one side of the through-hole 120, and along the radial direction of the laundry treatment drum 100, the inner end of the scraper 510 (one end of the scraper 510) is connected to the laundry treatment drum 100, and the outer end of the scraper 510 (the other end of the scraper 510) protrudes outward relative to the outer circumference of the laundry treatment drum 100. It should be noted that the degree of protrusion of the outer end of the scraper 510 should not affect the rotation of the laundry treatment drum 100 relative to the second barrel 600.

[0104] The arrangement of the scraper 510 forms an oblique hole on the inner cylinder, and the oblique hole faces the outside of the clothing treatment cylinder 100. In the process of the clothing treatment device treating the clothes, the second cylinder 600 (outer cylinder) is always stationary. When the clothing treatment cylinder 100 (inner cylinder) rotates, a speed difference is formed between the inner and outer cylinders. At this time, the oblique hole opened on the clothing treatment cylinder 100 (inner cylinder), that is, the scraper 510, continuously scrapes the water between the inner and outer cylinders, forcing it to flow to the through-port 120, and then enter the receiving chamber 210, and after passing through the filter, it flows to the clothing treatment chamber 110 of the clothing treatment cylinder 100 (inner cylinder). In other words, this structure forces a passive water flow to be formed between the inner and outer cylinders. The water suspended by the scraper 510 is also the external water flow, which contains debris such as hair scraps. The debris such as hair scraps can be filtered by the filter and collected in the receiving chamber 210 of the receiving member 200.

[0105] Optionally, along the reverse direction of the rotation direction B of the laundry processing drum 100 , the scraper 510 gradually tilts toward the inside of the laundry processing drum 100 .

[0106] The scraper 510 may be disposed upstream of the through opening 120 along the rotation direction B of the laundry treatment tub 100 to facilitate the water flow to be introduced into the communication hole 415. Specifically, as Figures 2 to 4As shown, the laundry treatment drum 100 can be configured to rotate clockwise about its own axis. The scraper 510 is disposed on the side of the through opening 120 in the counterclockwise direction, and the scraper 510 is inclined gradually closer to the inner side of the laundry treatment drum 100 in the counterclockwise direction. When the laundry treatment drum 100 rotates clockwise, the water on the scraper 510 is guided countercurrently along the side of the scraper 510 facing the diversion port to the through opening 120 and flows into the accommodation cavity 210 through the second opening 230 or the through opening 120. Under the action of the centrifugal force of the laundry treatment drum 100, the scraper 510 has a greater effect of scraping and guiding the external water flow, which is more conducive to the collection of debris such as lint.

[0107] In this embodiment, one or more (more than two) accommodation members 200 can be provided. When multiple accommodation members 200 are provided, the multiple accommodation members 200 can be arranged at intervals in the circumferential direction of the laundry treatment drum 100, or can be dispersed along the axial direction A of the laundry treatment drum 100. In a specific embodiment, referring to Figure 1 As shown, in this embodiment, a plurality of accommodation members 200 are provided, and the plurality of accommodation members 200 are arranged at intervals in the circumferential direction of the laundry treatment drum 100.

[0108] In some embodiments, reinforcing ribs 130 are provided on the laundry treatment drum 100. The reinforcing ribs 130 are located inside the laundry treatment drum 100 and protrude into the laundry treatment cavity 110. The accommodation member 200 can be provided at the position of the reinforcing ribs 130. It can be that mounting openings are provided on the reinforcing ribs 130, and the mounting openings communicate the outside and the laundry treatment cavity 110 of the laundry treatment drum 100, and the accommodation member 200 is installed in the mounting openings. It can also be that the accommodation member 200 is formed by a partial or integral part of the reinforcing ribs 130, that is to say, the accommodation member 200 in this application is a part of the reinforcing ribs 130 or the reinforcing ribs 130 are integrally formed. As Figures 2 to 4 As shown, in this embodiment, the reinforcing ribs 130 can all form the accommodation member 200, that is to say, the accommodation member 200 serves as the reinforcing ribs 130.

[0109] Among them, the reinforcing ribs 130 can extend along the axial direction A of the laundry treatment drum 100. Two or more reinforcing ribs 130 can be provided on the laundry treatment drum 100. The multiple reinforcing ribs 130 can be arranged at intervals in the circumferential direction of the laundry treatment drum 100. At least one of the multiple reinforcing ribs 130 is provided with or forms the accommodation member 200. In a specific embodiment, as Figure 1 As shown, the multiple reinforcing ribs 130 are arranged at equal intervals in the circumferential direction of the laundry treatment drum 100, and the accommodation member 200 is formed on each reinforcing rib 130. Specifically, the number of the reinforcing ribs 130 can be 3.

[0110] The receiving member 200 may include a housing located within the laundry processing chamber 110, which includes a bottom plate 201, end plates 203, and side plates 202. The bottom plate 201 is spaced from the laundry processing drum 100 and is disposed opposite the second opening 230. The side plates 202 and the end plates 203 are connected between the laundry processing drum 100 and the bottom plate 201. The side plates 202 are disposed on both sides in the drum rotation direction B, and the first opening 220 is disposed on the side plates 202. The end plates 203 are disposed at both ends of the bottom plate 201 in the axial direction A of the laundry processing drum 100 and are connected to the side plates 202 to define a receiving cavity 210. The connecting shaft 414 of the baffle 411 may extend along the axis of the laundry processing drum 100 and is rotatably connected to the end plates 203 at both ends.

[0111] The housing of the receiving member 200 further includes two first partition plates 204, which are spaced between the two end plates 203. The two first partition plates 204 are connected to the bottom plate 201 and form a receiving cavity 210 with the bottom plate 201. An isolation cavity 219 is formed between the first partition plates 204 and the end plates 203. The connecting shaft 414 passes through the first partition plates 204 and extends into the isolation cavity 219, and the connecting shaft 414 is rotatably connected to both the first partition plates 204 and the end plates 203. Torsion springs 413 may be disposed at both ends of the connecting shaft 414 and located within the isolation cavity 219. A positioning member 217 is disposed within the isolation cavity 219, and the positioning member 217 is connected to the first partition plates 204 and the end plates 203, and the positioning member 217 is connected to the torsion springs 413.

[0112] A first opening 220 may be disposed on one side plate 202 of the housing. On the inner side of the other side plate 202 of the housing, a second partition plate 205 may be disposed. The second partition plate 205 is connected to the two first partition plates 204 and the bottom plate 201 at both ends. A receiving cavity 210 is formed between the second partition plate 205, the two first partition plates 204, and the side plate 202 provided with the first opening 220. A connecting portion 218 may be disposed between the side plate 202 not provided with the first opening 220 and the second partition plate 205. Fasteners such as screws pass through the connecting portion 218 to fix the housing to the laundry processing drum 100.

[0113] It should be noted that a connecting portion 218 may also be disposed within the isolation cavity 219 for fixing the housing to the laundry processing drum 100.

[0114] In this embodiment, a receiving member 200 may be provided with a plurality of first one-way conduction members 410. A plurality of baffles 411 may be provided. The plurality of baffles 411 may be arranged along the rotation direction B of the laundry processing drum 100, or may also be arranged along the axial direction A of the laundry processing drum 100. The plurality of baffles 411 are jointly used to control the opening and closing of the second opening 230. Among them, when the plurality of baffles 411 are all in contact with the corresponding stoppers 240, the second opening 230 is closed. When one or more of the baffles 411 are movable, the second opening 230 can be made conductive, and the directions in which the plurality of baffles 411 can move are the same. In this embodiment, as Figure 6 shown, there are four baffles 411, which are divided into two groups. Two of the baffles 411 in one group are arranged along the axial direction A of the laundry processing drum 100 and are connected to the same connecting shaft 414. The other two baffles 411 in the other group are arranged along the axial direction A of the laundry processing drum 100 and are connected to the same connecting shaft 414. The two groups of baffles 411 are arranged in sequence along the rotation direction B of the laundry processing drum 100.

[0115] Among them, the housing may be provided with a third partition 206 between the two baffles 411 in each group. The connecting shaft 414 passes through the third partition 206 and is rotatably connected to the third partition 206. The third partition 206 can position the two baffles 411 arranged along the axial direction A of the laundry processing drum 100.

[0116] It should be noted that when a receiving member 200 has a plurality of first one-way conduction members 410, all of the first one-way conduction members 410 may be provided with communication holes 415 and connected to second one-way conduction members 420, or a partial number of the first one-way conduction members 410 may be provided with communication holes 415 and connected to second one-way conduction members 420.

[0117] In this embodiment, a first one-way conduction member 410 may be provided with one or more communication holes 415. When a first one-way conduction member 410 is provided with a plurality of communication holes 415, a second one-way conduction member 420 may be respectively provided corresponding to the plurality of communication holes 415, or a second one-way conduction member 420 may simultaneously control the opening and closing of the plurality of communication holes 415. In this embodiment, a plurality of communication holes 415 are provided on one baffle 411, and a valve plate 421 is provided corresponding to some adjacent communication holes 415 among the plurality of communication holes 415.

[0118] Taking the configuration of the baffle 411 and the valve plate 421 as an example, where the baffle 411 rotates under the rotational action of the laundry treatment drum 100 at a preset rotational speed, and the valve plate 421 moves and opens the communication hole 415 under the impact of external water flow, the principle of collecting and cleaning debris in the laundry treatment drum of this embodiment will be specifically described. In this embodiment, the first end of the baffle 411 is rotatably connected to the receiving member 200 through a connecting shaft 414. A stopper 240 is provided inside the second end of the baffle 411. A torsion spring 413 is sleeved on the connecting shaft 414. When the torsion spring 413 is used to apply a force to the baffle 411 to close the second opening 230; a limiting boss 417 is provided on the circumferential edge of the baffle 411. The valve plate 421 is arranged inside the limiting boss 417. A clamping groove 416 is provided on the side of the baffle 411 facing the receiving cavity 210. A clamping protrusion 422 is provided at the first end of the valve plate 421. The clamping protrusion 422 is clamped in the clamping groove 416. The second end of the valve plate 421 is used to abut against the side of the baffle 411 facing the receiving cavity 210 to seal the communication hole 415. A through hole 120 is provided on the laundry treatment drum 100, and a scraping plate 510 is inclined corresponding to the through hole 120. The scraping plate 510 has a certain outward convex height to facilitate water scraping without affecting the gap between the inner and outer cylinders. Using the rotational speed difference between the inner and outer cylinders (the laundry treatment drum 100 and the second cylinder 600), a passive water flow is forcibly formed. The reinforcing rib 130 forms the receiving member 200. The internal space of the reinforcing rib 130 serves as a debris storage space, and a filtering member is arranged therein.

[0119] In the first state, the second opening 230 of the receiving member 200 is the water inlet end, and the first opening 220 is the water outlet end. The valve plate 421 functions as a one-way valve. When external water flow enters the receiving cavity 210, the valve plate 421 can be easily washed open by the external water flow, and the external water flow smoothly passes through the communication hole 415; when the water in the receiving cavity 210 wants to flow back from the water inlet end, the valve plate 421 closes tightly to prevent the water flow from passing through. As Figure 8 and Figure 9 shown, when the inner cylinder (the laundry treatment drum 100) rotates counterclockwise, a passive water flow is generated, and filtration can be achieved. When it rotates clockwise, due to the one-way opening function of the valve plate 421, backflow can be prevented; this process can also be referred to Figure 3 shown, where Figure 3 in, when the inner cylinder (the laundry treatment drum 100) rotates clockwise, a passive water flow is generated, and filtration can be achieved. Among them Figure 3 , Figure 8 and Figure 9 the arrow C shown represents the flow direction of the external water flow.

[0120] The baffle 411 itself should have a counterweight to facilitate the opening of the baffle 411 by centrifugal force. The torsion spring 413 on the connecting shaft 414 of the baffle 411 and its own configuration satisfy the following principle: when the laundry treatment device is washing clothes normally, although the rotation speed of the laundry treatment drum 100 is slow, there is also a centrifugal force at this time. Therefore, the torsion spring 413 needs to be able to resist the centrifugal force in this case to ensure that the baffle 411 is tightly closed. When the laundry treatment device enters the dehydration stage, it is hoped that the debris such as lint clusters in the collection chamber can be discharged at this time. Therefore, in the dehydration stage, the baffle 411 should be able to be smoothly opened by the centrifugal force. In this way, due to the existence of the torsion spring 413, the baffle 411 is in a state of closing the second opening 230 under normal circumstances (when the laundry treatment drum 100 of the laundry treatment device is stationary or at a low rotation speed during normal washing). When the baffle 411 is in the closed state, the receiving member 200 can perform normal debris collection operations. If the baffle 411 is subjected to a large centrifugal force, the baffle 411 can rotate and move towards the outer cylinder (the second cylinder 600) to open the second opening 230. At this time, the receiving member 200 cannot collect debris, but the debris in the receiving cavity 210 (such as the previously collected lint clusters) can enter the space between the inner and outer cylinders through the opened second opening 230. That is to say, as Figure 4 and Figure 10 shown, the cleaning of debris utilizes the principle of centrifugal force. When the laundry treatment device is dehydrating, the inner cylinder (the laundry treatment drum 100) rotates at a high speed, and the centrifugal acceleration increases much more than that in the normal washing state. The large centrifugal force opens the baffle 411 on the receiving member 200, and the debris such as lint clusters in the receiving member 200 are centrifugally thrown out. Then, under the flushing of the wall-attached water flow, the debris is finally brought to the discharge port 610 of the laundry treatment device and then discharged from the laundry treatment device. Among them Figure 4 and Figure 10 the arrow D shown in indicates the flow direction of the internal water flow, Figure 10 and the arrow E in indicates the direction in which the water flow carries the debris out.

[0121] Among them, in the laundry washing state, there is a relatively large amount of free water in the laundry treatment chamber 110. This water can enter between the laundry treatment cylinder 100 and the second cylinder 600 and be lifted by the scraper 510. Therefore, the valve plate 421 can be unidirectionally opened and enter the receiving chamber 210 to collect debris and other sundries. When the baffle 411 is opened under the action of centrifugal force, the laundry treatment device usually has drained the free water (water not absorbed by the laundry) in the laundry treatment chamber 110, and the laundry treatment device is at a rotational speed higher than the washing state. That is to say, the centrifugal force generated by the rotation of the laundry treatment cylinder 100 in the laundry washing state cannot overcome the acting force of the torsion spring 413 to open the second opening 230. Therefore, in the laundry washing stage, only the valve plate 421 unidirectionally opens the communication hole 415. After the free water is drained in the laundry dehydration stage, there is basically no free water between the laundry treatment cylinder 100 and the second cylinder 600, and the scraper 510 can basically not lift water. Therefore, only the baffle 411 unidirectionally opens the second opening 230. In the stage of draining free water in the laundry dehydration stage, the baffle 411 can be in a state of closing the second opening 230 and the valve plate 421 can be in a state of closing the communication hole 415.

[0122] For the laundry treatment cylinder of this embodiment, by providing the scraper 510, the ability of the laundry treatment device to collect sundries can be enhanced, and the sundries collected in the receiving member 200 can be automatically removed without the need to stop the laundry treatment device, which is convenient and fast to operate.

[0123] Some embodiments of the present application further provide a laundry treatment device, including a second cylinder 600 and the laundry treatment cylinder proposed in the present application or any embodiment of the present application. Among them, the laundry treatment cylinder 100 of the laundry treatment cylinder is located inside the second cylinder 600, and the laundry treatment cylinder 100 is rotatably arranged relative to the second cylinder 600.

[0124] The laundry treatment device may further include a housing. The second cylinder 600 is arranged inside the housing and fixedly arranged with the housing. The discharge port 610 of the second cylinder 600 is communicated with the liquid discharge port of the laundry treatment device. The second cylinder 600 is equivalent to an outer cylinder, and the laundry treatment cylinder 100 is equivalent to an inner cylinder. A driving device for driving the rotation of the laundry treatment cylinder 100 may also be arranged inside the housing. The laundry treatment device may further include other related components for laundry treatment, such as a water inlet assembly, a detergent accommodating assembly, a controller, etc.

[0125] The laundry treatment device of this embodiment may be a side-opening drum washing machine. Specifically, the laundry treatment cylinder 100 and the second cylinder 600 are provided with a communicated laundry pick-up and drop-off opening, and the laundry pick-up and drop-off opening is arranged on the side of the laundry treatment device.

[0126] In some embodiments, the movable component 400 is configured such that when the laundry treating apparatus is in the laundry washing stage, the movable component 400 is in the first state, and when the laundry treating apparatus is in the laundry dehydration stage, the movable component 400 is in the second state.

[0127] Specifically, it can be that the laundry treating apparatus automatically controls the laundry treating apparatus to be in the corresponding sundry treatment process according to the working stage it is in through the controller of the laundry treating apparatus. It can also be that the relevant structure of the laundry drum automatically controls the laundry treating apparatus to be in the corresponding sundry treatment process according to the different acting forces that can be generated in the working stage of the laundry treating apparatus.

[0128] Specifically, in some embodiments, the movable component 400 is configured such that when the laundry treating apparatus is in the laundry washing stage and the laundry drum 100 is in a rotating state, the movable component 400 causes the second opening 230 to conduct under the impact of the external water flow outside the laundry drum 100, so that the laundry treating apparatus is in the process of collecting sundries.

[0129] Specifically, it can be that the valve piece 421 opens the communication hole 415 under the impact of the external water flow, thereby realizing the one-way conduction of the second opening 230 in the laundry washing stage.

[0130] Optionally, the movable component 400 can also be configured such that when the laundry treating apparatus is in the laundry dehydration stage and the rotation speed of the laundry drum 100 is at a preset rotation speed, the movable component 400 causes the second opening 230 to open under the centrifugal force of the rotation speed of the laundry drum 100, so that the laundry treating apparatus is in the process of cleaning sundries. The preset rotation speed is greater than the maximum rotation speed of the laundry drum 100 in the laundry washing stage.

[0131] Specifically, it can be that the baffle 411 causes the second opening 230 to open under the centrifugal force of the rotation of the laundry drum 100, and makes the second opening 230 conduct unidirectionally in the laundry dehydration stage.

[0132] Wherein, the lower limit value of the preset rotation speed ranges from the rotation speed of the laundry drum 100 when the cumulative water output of the laundry in the laundry treating apparatus reaches 30% to 80% of the total water output of the laundry.

[0133] Among them, the lower limit value of the preset rotation speed is the minimum value of the preset rotation speed. That is to say, when the laundry drum 100 reaches or is approximately at this lower limit value, the movable component 400 (baffle 411) can cause the second opening 230 to open under the action of centrifugal force. The total amount of water discharged from the laundry is the total amount of all water adsorbed by the laundry. Specifically, after the free water in the laundry treatment chamber 110 of the laundry treatment device is discharged, the laundry drum 100 starts to rotate, causing the laundry in the laundry treatment device to discharge the adsorbed water. During the rotation of the laundry drum 100, the total amount of water discharged by the laundry treatment device can be considered as the total amount of water discharged from the laundry. The cumulative amount of water discharged from the laundry is the total amount of water discharged by the laundry from the start of the rotation of the laundry drum 100 to the current moment. During the dehydration stage of the laundry treatment device, the process of water adsorption and discharge from the laundry is less at the beginning, more in the middle, and less at the end. The lower limit value of the preset rotation speed can be set to the middle stage when the water adsorbed by the laundry is discharged the most. Specifically, it can be when the cumulative amount of water discharged from the laundry reaches 30%, 40%, 50%, 55%, 60%, 70%, 80%, etc. of the total amount of water discharged from the laundry.

[0134] The value range of the lower limit value of the preset rotation speed can also be 30% to 60% of the maximum rotation speed of the laundry treatment device. Specifically, the lower limit value of the preset rotation speed can be 30%, 40%, 50%, 60%, etc. of the maximum rotation speed of the laundry treatment device.

[0135] Among them, the rotation speed during the dehydration stage of the laundry treatment device can increase in a stepped manner, and the lower limit value of the preset rotation speed is set to the middle stage of the rotation speed of the laundry treatment device.

[0136] In one embodiment, the value range of the lower limit value of the preset rotation speed is 300 revolutions per minute to 500 revolutions per minute.

[0137] The maximum rotation speed of the laundry treatment device can be 800 revolutions per minute or 1000 revolutions per minute. The specific limit values of the preset rotation speed can be 300 revolutions per minute, 350 revolutions per minute, 400 revolutions per minute, 500 revolutions per minute.

[0138] In a specific embodiment, the lower limit value of the preset rotation speed is set to about 400 revolutions per minute.

[0139] It can be understood that the limitation of the preset rotation speed in the embodiments of the present application can not only reduce the possibility of the failure of the debris collection due to the unidirectional conduction of the movable component 400 (baffle 411) in the washing state, but also enable better cleaning ability of the debris. Taking the lower limit value of the preset rotation speed as 400 revolutions per minute as an example, when the dehydration rotation speed of the laundry drum 100 reaches about 400 revolutions per minute, the centrifugal force on the baffle 411 can reach a value greater than the torque of the torsion spring 413 to open the baffle 411. This is because if the rotation speed at which the baffle 411 can be opened is not high enough and is not sufficient to widen the rotation speed difference from the normal washing rotation speed, then there is a high probability that the low rotation speed (about 60 revolutions per minute) of the laundry drum 100 during normal washing will open the baffle 411, which will obviously make the function of the receiving member 200 unreliable. In addition, if the dehydration rotation speed of the drum is much greater than 400 revolutions per minute when the centrifugal force on the baffle 411 can reach the degree to open the baffle 411, then since most of the water on the clothes has already been thrown out, at this time, debris such as lint balls in the receiving member 200 can only move out by their own centrifugal force. Moreover, after the debris enters the space between the inner and outer drums, it is likely to be thrown and adhered to the outer drum wall. Then, without the flushing of water flow, it will adhere to the outer drum wall for a long time until it may be flushed down during the next laundry. In this way, secondary pollution will be caused and the effect of debris collection will not be achieved.

[0140] It should be noted that in this embodiment, the lint collection process is not limited to being during the laundry washing process. As long as there is water in the laundry treatment chamber 110 and the water can enter between the laundry drum 100 and the second cylinder 600, the laundry drum 100 can be configured to rotate to enable the receiving member 200 to collect debris. The lint cleaning process is not limited to being completed during the laundry dehydration stage. In some cases, the rotation speed of the laundry treatment device can also be directly set within the preset rotation speed to achieve the lint cleaning process.

[0141] The above descriptions of the various embodiments tend to emphasize the differences between the various embodiments. Their similarities or similarities can be referred to each other. For the sake of brevity, they will not be elaborated herein. The descriptions of the laundry drum and the laundry treatment device of any embodiment of the present application can be borrowed from each other.

[0142] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
