The present embodiment is described by taking the dial assembly 40 as an example of the clothes treating apparatus, and it is understood that the dial assembly 40 can be applied to other fields. Specifically, the embodiment of the present application provides a clothes treating apparatus, please refer to fig. 3 to 7, the clothes treating apparatus includes an inner cylinder 11, a dial assembly 40, a drain assembly 20 and a shift lever 51; the inner cylinder 11 can contain water, that is, when the clothes treatment equipment is used for washing clothes, the washing water is contained in the inner cylinder 11, the inner cylinder 11 can also be called a non-porous inner cylinder, so that the problem that dirt and dirt are easily stored in the outer cylinder when the water is contained in the outer cylinder in the prior art can be solved; a water discharge hole 110 is formed on the inner cylinder 11; referring to fig. 8, the drainage assembly 20 includes a driving rod 22 and a sealing member 21, wherein one end of the driving rod 22 is fixedly connected to the dial 41, so that the dial 41 can rotate around a first rotation center O, which is located on the rotation center line L1, to drive the rod 22 to rotate, that is, the driving rod 22 has a rotation center line L1; the other end of the driving rod 22 drives the sealing member 21 to switch between a sealing position for sealing the drain hole 110 and an avoiding position for avoiding the drain hole 110; the shift lever 51 can be selectively extended or retracted toward the dial assembly 40, and in a condition where the shift lever 51 is extended, the shift lever 51 can abut against one side of the first dial 42 and/or the second dial 43 in the rotation direction of the inner cylinder 12, that is, the shift lever 51 can interfere with the first dial 42 and/or the second dial 43.

Referring to fig. 5 and 6, since the inner cylinder 12 rotates, the position of the shift lever 51 is not changed, and therefore, the rotation track of the shift lever 51 on the inner cylinder 12 is a circle I. The first center of rotation O has a trajectory that is circular pi since the dial assembly 40 follows the synchronous movement of the inner barrel 12.

Referring to fig. 5, the sealing member 21 is in the sealing position, the first toggle member 42 is located outside the circle I, when the toggle lever 51 extends toward the dial assembly 40, the first toggle member 42 does not contact the toggle lever 51, and the second toggle member 43 has an overlapping portion with the circle I. If the inner cylinder 11 rotates clockwise in fig. 5, when the shift lever 51 abuts against a side of the second dial 43 away from the first dial 42, the shift lever 51 forces the second dial 43 to rotate clockwise around the second rotation point a2, and when the dial assembly 40 continues to rotate along with the inner cylinder 11 until the second dial 43 disengages from the shift lever 51, the second dial 43 is reset by the elastic reset unit 46; the movement process after the inner cylinder 11 rotates for a circle is the same as the above, and in the process, even if the shift lever 51 extends out, the shift lever 51 does not influence the rotation of the inner cylinder 11, the inner cylinder 11 cannot be locked, and the sealing performance of the sealing element 21 cannot be influenced.

When the sealing member 21 needs to be switched from the sealing position shown in fig. 5 to the avoiding position shown in fig. 6, the inner cylinder 11 is reversed, that is, the inner cylinder 11 rotates in the counterclockwise direction of fig. 5, when the dial assembly 40 rotates along with the inner cylinder 11 until the shift lever 51 abuts against the side of the second dial 43 facing the first dial 42 (the position shown in fig. 5), the second dial 43 cannot rotate freely under the action of the second stopper 45, the second dial 43 forces the dial 41 to rotate counterclockwise around the first rotation center O, that is, when the dial 41 revolves around the rotation axis L2 of the inner cylinder 11 and also rotates around the first rotation center O, during the counterclockwise rotation of the dial 41 around the first rotation center O, the first dial 42 gradually coincides with the circle I, the second dial 43 gradually moves away from the circle I, when the dial assembly 40 disengages from the shift lever 51 as the inner cylinder 11 rotates to the second dial 43, referring to fig. 6, that is, the second toggle element 43 is located outside the circle I, the toggle element 51 no longer forces the dial 41 to rotate, the torque of the dial 41 on the driving rod 22 disappears, the driving rod 22 does not drive the sealing member 21 to move, that is, the dial 41 and the toggle element 51 no longer interfere with the movement of the sealing member 21, and in this case, the sealing member 21 is already in the avoidance position or can continue to move to the avoidance position by the driving of other reset elements. It should be noted that, when the sealing member 21 can continue to move under the driving of other reset members, the sealing member 21 can drive the dial 41 to continue to rotate counterclockwise by a certain angle through the driving rod 22.

In the rotating process that the inner cylinder 11 enters the next circle, when the inner cylinder is rotated to the position that the shifting lever 51 abuts against one side of the first shifting piece 42, which is far away from the second shifting piece 43, the shifting lever 51 forces the first shifting piece 42 to rotate anticlockwise around the first rotating point A1, after the shifting lever 51 passes through the first shifting piece 42, the first shifting piece 42 resets under the action of the elastic resetting unit 46, and the second shifting piece 43 is not in contact with the shifting lever 51, so that the shifting lever 51 cannot influence the rotation of the inner cylinder 11, and the stability of the sealing element 21 at the avoiding position is not influenced.

When it is necessary to switch from the retracted position shown in fig. 6 to the sealing position shown in fig. 5, the inner cylinder 11 rotates clockwise in fig. 6, and the principle is the same as that of switching from the sealing position to the retracted position, and the description thereof is omitted.

It should be noted that if the shift lever 51 extends at a position intermediate between the sealing position and the avoiding position, i.e. when the first toggle member 42 and the second toggle member 43 both have a portion coinciding with the circle I, and may be located directly between the first toggle member 42 and the second toggle member 43, depending on the rotation direction of the inner cylinder 11, if the inner cylinder 11 rotates clockwise as shown in fig. 5 or 6, the shift lever 51 will force the first shift lever 51 to drive the dial 41 to rotate clockwise, and if the inner cylinder 11 rotates counterclockwise, the shift lever 51 will force the second shift lever 51 to drive the dial 41 to rotate counterclockwise.

If the shift lever 51 extends outside of the first toggle member 42 and the second toggle member 43, that is, the shift lever 51 is not located between the first toggle member 42 and the second toggle member 43. Under the condition that the inner cylinder 11 rotates counterclockwise in fig. 5 or 6, the shift lever 51 abuts against a side of the first dial 42 away from the second dial 43, the shift lever 51 forces the first dial 42 to rotate counterclockwise around the first rotation point a1, after the shift lever 51 passes over the first dial 42, the first dial 42 is reset under the action of the elastic reset unit 46, and the shift lever 51 further forces the second dial 43 to drive the dial 41 to rotate counterclockwise, and then reaches the position shown in fig. 6. If the inner cylinder 11 rotates clockwise, when the dial plate assembly 40 rotates along with the inner cylinder 11 until the shift lever 51 abuts against one side of the second dial 43 away from the first dial 42, the second shift lever 51 rotates freely around the second rotation point a2, when the shift lever 51 passes over the second shift lever 51, the second shift lever 51 is reset under the action of the elastic reset unit 46, the dial plate assembly 40 moves continuously according to the inner cylinder 11 until the shift lever 51 abuts against one side of the first dial 42 toward the second dial 43, the first dial 42 cannot rotate freely, the dial plate 41 forces the first dial 42 to drive the dial plate 41 to rotate clockwise around the first rotation center O, and then the position shown in 5 is reached.

It should be noted that the shift lever 51 may be retracted at an appropriate time, for example, the shift lever 51 may be retracted after the inner cylinder 11 rotates one or several times.

From the above, the dial assembly 40 of the embodiment of the present application can output two torques in opposite directions without locking the inner cylinder 11, and has the advantages of ingenious concept, simple structure and high reliability.

In one embodiment, referring to fig. 1 and 2, a perpendicular line passing through the first rotation point a1 and perpendicular to a connection line between the first rotation point a1 and the second rotation point a2 is a first perpendicular line, a perpendicular line passing through the second rotation point a2 and perpendicular to a connection line between the first rotation point a1 and the second rotation point a2 is a second perpendicular line, and the first rotation center O is located between the first perpendicular line and the second perpendicular line, so that the layout of the first toggle member 42, the second toggle member 43 and the first rotation center O can be more compact and reasonable, and the space occupied by the dial assembly 40 can be reduced as much as possible.

In an embodiment, referring to fig. 1 and fig. 2, the first position-limiting portion 44 is a first protrusion protruding from the surface of the dial 41; and/or the second limiting part 45 is a first protrusion protruding from the surface of the dial 41. The specific structural form of the first protrusion is not limited as long as the first poking member 42 can be prevented from rotating; the first position-limiting portion 44 and the dial 41 may be formed integrally, or may be formed separately and fixedly connected. Similarly, the specific structural form of the second protrusion is not limited as long as the second poking member 43 can be prevented from rotating; the second limiting portion 45 and the dial 41 may be formed integrally, or may be formed separately and fixedly connected.

For example, referring to fig. 1, in an embodiment, the elastic reset unit 46 is a tension spring, the tension spring is connected between the first shifting member 42 and the second shifting member 43, specifically, the tension spring and the first position-limiting portion 44 are located at two opposite ends of the first shifting member 42 along the first rotation point a1, the tension spring and the second position-limiting portion 45 are located at two opposite ends of the second shifting member 43 along the first rotation point a1, the tension spring applies a moment around the first rotation point a1 to the first shifting member 42, and the first shifting member 42 abuts against one side of the first position-limiting portion 44 under the action of the moment. Similarly, the tension spring applies a moment around the second rotation point a2 to the second dial 43, and the second dial 43 abuts against one side of the second limiting portion 45 under the action of the moment.

Similarly, the second position-limiting portion 45 may be disposed close to the second rotation point a2, or may be disposed far from the second rotation point a2, as long as the second position-limiting portion 45 does not interfere with the shift lever 51.

In the clothes treatment equipment of the embodiment of the application, in the washing process or other occasions without water drainage, the sealing element 21 is in the sealing position, the water drainage hole 110 is blocked by the sealing element 21, and water in the inner drum 11 cannot flow out of the inner drum 11; when drainage or dehydration is required, the driving rod 22 drives the sealing element 21 to move, the sealing element 21 moves to the avoidance position, the drain hole 110 is opened, and water in the inner cylinder 11 is drained out of the inner cylinder 11 through the drain hole 110.

In one embodiment, referring to fig. 7, the water discharge holes 110 are formed in the rotation circumferential direction of the inner drum 11, so that the water is thrown out of the water discharge holes 110 by centrifugal force during the dehydration process of the inner drum 11; the dial assembly 40 is disposed outside the inner cylinder 11 along the direction of the rotation axis L2, one end of the driving rod 22 away from the sealing member 21 protrudes outside the inner cylinder 11 along the direction of the rotation axis L2, that is, the extending direction of the driving rod 22 is substantially parallel to the direction of the rotation axis L2 of the inner cylinder 11, the dial assembly 40 rotates along with the inner cylinder 11, the dial 41 always faces one side of the shift lever 51, that is, the dial face of the dial 41 rotates in the same plane, the first shift member 42 (or the second shift member 43) can have a certain contact time with the shift lever 51 under the condition that the position of the shift lever 51 is not changed, and the shift lever 51 can gradually separate from the first shift member 42 (or the second shift member 43) during the process that the inner cylinder 11 drives the dial 41 to rotate.

In the embodiment of the present application, the dial 41 includes a first position and a second position in the rotational direction; when the dial 41 is rotated to the first position, the shift lever 51 and the first dial 42 can be disengaged, and thereafter the shift lever 51 no longer interferes with the first dial 42, that is, the dial 51 no longer forces the first dial 42 to rotate the dial 41; the dial 41 is rotated to the second position, the shift lever 51 and the second dial 43 can be disengaged, after which the shift lever 51 no longer interferes with the first dial 42, i.e. the dial 51 no longer forces the first dial 42 to rotate the dial 41.

Specifically, in one embodiment, before or while the seal 21 moves to the retracted position, the dial 41 rotates to the first position, that is, during switching of the seal 21 from the sealing position to the retracted position, before or at the latest while the seal 21 moves to the retracted position, the shift lever 51 and the second shift member 43 disengage, preventing the inner cylinder from being locked. Before or simultaneously with the movement of the seal 21 to the sealing position, the dial 41 is rotated to the second position, that is, during the switching of the seal 21 from the escape position to the sealing position, the shift lever 51 and the first shift member 42 are disengaged before or at the latest when the seal 21 is moved to the sealing position, preventing the inner cylinder from being locked.

In order to avoid interference of other objects with the movement of the sealing member 21 and the driving rod 22, in the embodiment of the present application, referring to fig. 8, 9, 12, 15 and 19, the clothes treating apparatus further includes a cover 30, a side of the cover 30 facing the water discharge hole 110 is open, the cover 30 and the inner drum 11 together enclose a receiving cavity 301, the sealing member 21 and a portion of the driving rod 22 are disposed in the receiving cavity 301, and an end of the driving rod 22 away from the sealing member 21 extends out of the receiving cavity 301, that is, an end of the driving rod 22 is located outside the receiving cavity 301. The cover 30 provides an installation space for the sealing member 21 and the driving rod 22, and also protects the sealing member 21 and the driving rod 22, thereby improving the reliability of the drainage structure.

The drain module 20 may seal the drain hole 110 and the escape drain hole 110 from the outside of the inner cylinder 11, or may seal the drain hole 110 and the escape drain hole 110 from the inside of the inner cylinder 11, as long as it can switch between the sealing position and the escape position as necessary.

In the embodiment of the present application, referring to fig. 7, the drainage assembly 20 seals the drainage hole 110 and avoids the drainage hole 110 from the inner side of the inner drum 11, that is, the sealing member 21 is located at the inner side of the inner drum 11, so that the sealing member 21, the driving rod 22 and other structures do not interfere with the outer drum 12 and other structures during the rotation of the inner drum 11, the gap between the inner drum 11 and the outer drum 12 can be reduced, and the structure of the laundry processing apparatus is more compact.

The cover 30 may be provided separately in the inner tub 11, or may be an existing structure using a laundry treatment apparatus. For example, in the embodiment of the present application, please refer to fig. 8, 9, 12, 15 and 19, the cover 30 is a lifting rib 30 "disposed in the inner cylinder 11, that is, the sealing element 21 and a part of the driving rod 22 are disposed in the lifting rib 30". In the process of washing clothes by the clothes treatment equipment, on one hand, the lifting ribs 30' carry the clothes to rotate together, and after the clothes are lifted to a certain height, the clothes fall into water again under the action of self gravity to generate the stick beating and falling effects, thereby achieving the washing effect. In the embodiment of the application, the existing structure of the clothes treatment equipment is fully utilized, the space inside the lifting rib 30' is fully utilized, and the capacity of washing clothes in the inner drum 11 can not be reduced.

The sealing member 21 is not limited in structural form, and may be made of rubber or silica gel as a whole, or may be made of a combination of hard material and soft material. In the embodiment of the present application, referring to fig. 10, 11, 13, 14, 17 to 21, the sealing member 21 includes a supporting frame 211 and a sealing ring 210, the sealing ring 210 is covered on an end portion of the supporting frame 211, the sealing ring 210 has a sealing surface 21a facing the water drain hole 110, and the sealing ring 210 seals the water drain hole 110 through the sealing surface 21 a. In this way, the support frame 211 serves as a main structure of the seal 21, and can improve the structural strength of the seal 21, prevent the seal 21 from being deformed such as warped or twisted, and improve the structural reliability of the seal 21. Further, in order to facilitate the connection between the sealing ring 210 and the supporting frame 211, a flange structure 2112 is formed at one end of the supporting frame 211 close to the sealing ring 210, and the sealing ring 210 is wrapped around the flange structure 2112, so that it is ensured that the sealing surface 21a has a sufficient sealing area, and the structure of the drainage assembly 20 is compact. During assembly, the sealing ring 210 is only required to be wrapped around the flange structure 2112, and the sealing ring 210 is tightly wrapped on the flange structure 2112 under the action of self elasticity and cannot be separated from the flange structure 2112.

The driving rod 22 may directly drive the sealing member 21 to move, or may indirectly drive the sealing member 21 to move through other structures. In the embodiment of the present application, the laundry treating apparatus includes a rotating member 23, at least a part of the rotating member 23 is connected between the sealing member 21 and the driving lever 22, the rotating member 23 has a second rotation center O ', the driving lever 22 drives the rotating member 23 to rotate around the second rotation center O', and the driving lever 22 drives the sealing member 21 to switch between the sealing position and the avoiding position through the rotating member 23. The transition connection between the drive rod 22 and the sealing element 21 via the rotary part 23 facilitates the conversion of the rotation of the drive rod 22 into the desired movement pattern of the sealing element 21 as required.

The rotating member 23 can drive the sealing member 21 in various manners, for example, in some embodiments, referring to fig. 8 to 14, the rotating member 23 drives the sealing member 21 to rotate around the second rotation center O'; in other embodiments, referring to fig. 15-22, the rotary member 23 drives the seal member 21 in translation. It should be noted that the translation refers to a straight line formed by connecting any two points on the sealing member 21, and the straight line is always parallel in the whole movement process of the sealing member 21.

It is understood that the second rotation center O' and the rotation center line L1 may be eccentrically disposed; it may be arranged concentrically, i.e. the second rotation center O' is located on the rotation center line L1.

In order to facilitate the sealing member 21 to be stably located at the sealing position after the torque of the driving rod 22 is removed during the washing process of the clothes treating apparatus, the drainage assembly 20 includes the elastic positioning member 25, and the elastic positioning member 25 applies a force to the sealing member 21 toward the drainage hole 110 when the sealing member 21 is located at the sealing position, so that the sealing member 21 can be stably and reliably abutted against the drainage hole 110 by the elastic positioning member 25 regardless of whether the torque of the driving rod 22 is removed or not.

The elastic positioning member 25 applies a force to the sealing member 21 toward the water discharge hole 110, which means that the force applied to the sealing member 21 by the elastic positioning member 25 may be a force itself along the moving direction of the sealing member 21, or a force having a component along the moving direction of the sealing member 21.

The resilient positioning element 25 may be a compression spring 25 "or a torsion spring 25'.

In the case of the elastic positioning member 25 using the torsion spring 25 ', the torsion spring 25 ' applies a second moment about the second rotation center O ' to the rotating member 23 in a condition where the sealing member 21 is in the escape position, the second moment being opposite to the first moment; alternatively, the elastic positioning member 25 is in a free state.

In some embodiments, the sealing member 21 and the torsion spring 25 'are coupled to opposite sides of the rotating member 23 along the second rotation center O'; in other embodiments, the sealing member 21 and the torsion spring 25 'are located on the same side of the rotating member 23 along the second rotation center O'.

The following description of the embodiments of the present application refers to the accompanying drawings

First embodiment

Referring to fig. 7 to 11, in the present embodiment, the rotation axis L2 of the inner cylinder 11 extends along the horizontal direction, the sealing member 21 seals the water discharge hole 110 from the inner side of the inner cylinder 11, and part of the structures of the sealing member 21, the rotation member 23, the torsion spring 25' and the driving rod 22 are disposed in the lifting rib 30 ″.

The second rotation center O 'is concentric with the rotation center line L1, that is, the second rotation center O' is located on the rotation center line L1, the driving lever 22 is fixedly connected with the rotation member 23, specifically, the driving lever 22 is connected to the second rotation center O 'of the rotation member 23, so that the rotation member 23 can drive the sealing member 21 to rotate around the second rotation center O', and thus, the connection structure between the driving lever 22, the rotation member 23 and the sealing member 21 is simple, and the consistency and reliability of the movement can be maintained.

The sealing member 21 and the torsion spring 25 'are connected to opposite sides of the rotating member 23 along the second rotation center O'.

It should be noted that the sealing member 21 and the rotating member 23 may be fixedly connected; or the sealing element can be hinged to form a movable included angle between the sealing element 21 and the inner wall of the inner cylinder 11, so that the sealing element 21 can be in better fit contact with the inner wall of the inner cylinder 11, the sealing performance is improved, and water leakage is prevented.

In order to better support the driving rod 22, in the embodiment, the drainage assembly 20 includes a supporting seat 24, a through hole (not shown) is formed on the supporting seat 24, and the driving rod 22 is rotatably disposed through the through hole. That is, the through-hole is located on the rotation center line L1. Further, the number of the supporting seats 24 is two, and the rotating member 23 is located between the two supporting seats 24, so that on one hand, the stress state of the driving rod member 22 can be improved, the driving rod member 22 is prevented from supporting the rotating member 23 in a cantilever manner, on the other hand, the two supporting seats 24 clamp the rotating member 23 in the middle, a certain limiting effect is performed on the rotating member 23, and the rotating member 23 is prevented from shifting along the direction of the rotating center line L1.

Further, in the present embodiment, the rotating member 23 includes the seat body 231 and the stopper 232, and the stopper 232 protrudes from one side of the seat body 231 along the rotation center line L1, that is, the stopper 232 abuts against one lateral side of the supporting seat 24 under the condition that the sealing member 21 is in the sealing position. When the driving rod 22 drives the rotating member 23 to rotate until the stopping portion 232 abuts against the supporting seat 24, the supporting seat 24 limits the further movement of the rotating member 23, and the torsion spring 25' applies the first torque W1 to the rotating member 23 to reliably abut the rotating member 23 against one side of the supporting seat 24.

The two opposite sides of the seat body 231 along the rotation center line L1 are both provided with the stopping portions 232, and the two stopping portions 232 and the support seat 24 are used for stopping and positioning, so that the stress condition of the rotating member 23 can be improved.

The operation principle and the operation process of the drain assembly 20 of the present embodiment will be described below.

Specifically, referring to fig. 10, when the sealing member 21 is in the sealing position, the torsion spring 25 'applies a force F1 to the rotating member 23, the force F1 generates a first torque W1 about the second rotation center O' to the rotating member 23, and the first torque W1 is clockwise in fig. 10. Referring to fig. 11, when the sealing member 21 is in the retracted position, the torsion spring 25 'applies a force F2 to the rotating member 23, the force F2 generates a second moment W2 about the second rotation center O' to the rotating member 23, and the second moment W2 is counterclockwise in fig. 11.

Since the first torque W1 is clockwise and the second torque W2 is counterclockwise, that is, when the sealing member 21 rotates between the sealing position shown in fig. 10 and the retracted position shown in fig. 11, the torque applied to the rotary member 23 by the torsion spring 25 'is reversed, specifically, there is a critical point at an intermediate position between the sealing position and the retracted position, at which the torque applied to the rotary member 23 by the torsion spring 25' is 0, and when the rotary member 23 passes the critical point, the torque applied to the rotary member 23 by the torsion spring 25 'is reversed, in which case, even if the torque of the driving lever member 22 is cancelled, the rotary member 23 can continue to rotate under the action of the second torque W2 applied by the torsion spring 25' until it moves to the position shown in fig. 11.

It will be appreciated that there should be structural elements blocking the seal 21 when the seal 21 is in the sealing position shown in figure 11, for example, it may be that part of the rotary member 23 abuts the support seat 24 described above. That is, the sealing position and the escape position are both extreme positions at which the sealing member 21 can move.

The seal 21 is switched from the sealing position shown in fig. 10 to the escape position shown in fig. 11 as an example. With the seal 21 in the sealed position, the state of the dial assembly 40 is with reference to fig. 5. The inner cylinder rotates in the counterclockwise direction in fig. 5, the driving lever 51 extends to force the second dial 43 to drive the dial 41 to rotate in the counterclockwise direction around the first rotation center line O, the driving rod 22 inputs the torque rotating in the counterclockwise direction in fig. 10, so that the rotating member 23 starts to rotate in the counterclockwise direction from the sealing position shown in fig. 10, and the driving rod 22 needs to continuously input the torque to overcome the clockwise first torque W1 applied to the rotating member 23 by the torsion spring 25' before the rotating member 23 crosses the above-mentioned critical point; when the rotating member 23 crosses the critical point, the torsion spring 25 ' reverses the moment of the rotating member 23, i.e., applies the second moment W2 in the counterclockwise direction, and even if the torque of the driving lever 22 is cancelled, the rotating member 23 can rapidly rotate counterclockwise to the avoiding position under the action of the torsion spring 25 ', and is locked at the avoiding position by the torsion spring 25 '. It should be noted that, during the rotation of the rotating member 23 driven by the torsion spring 25', since the driving lever 22, the rotating member 23 and the dial 41 are fixedly connected together, the driving lever 22 will in turn make the dial 41 rotate counterclockwise. The principle of switching the sealing member 21 from the escape position to the sealing position is the same as described above, and the direction is opposite to that described above, and thus, the description thereof is omitted.

Since the seal 21 is fixed after the sealing position and the avoiding position, if the shift lever 51 and the first or

second shift element

42 or 43 are not disengaged after the seal 21 has reached the sealing position or the avoiding position, the shift lever 51 may block the dial assembly 40, and thus the inner cylinder 12. To this end, the toggle lever 51 and dial assembly 40 are configured to: in the process of switching the sealing member 21 from the sealing position to the avoiding position, after the torque applied to the rotating member 23 by the torsion spring 25' is reversed, and before or while the sealing member 21 moves to the avoiding position, the dial 41 rotates to the second position, that is, the shift lever 51 is disengaged from the second shift member 43; during the switching of the sealing member 21 from the escape position to the sealing position, after the torque applied to the rotating member 23 by the torsion spring 25' is reversed, and before or while the sealing member 21 is moved to the sealing position, the dial 41 is rotated to the second position, that is, the shift lever 51 is disengaged from the first shift member 42. In this way, after the shift lever 51 is separated from the first dial 42 or the second dial 43, the dial 41 can continue to rotate in the same direction under the action of the torsion spring 25', so that the first dial 42 or the second dial 43 is further away from the dial 51, and the first dial 42 or the second dial 43 can be prevented from contacting with the dial 51 under the action of external vibration, and therefore, the reliability of the clothes treatment device can be further improved.

It will be appreciated that the torsion spring 25' in the first embodiment can also be in a free state when the sealing member 21 is in the retracted position, in which case, if the driving lever 22 is removed from the torque, the sealing member 21 is not stressed, the rotating member 23 cannot rotate in the counterclockwise direction in fig. 11, and the sealing member 21 is in a stationary state; when the rotating member 23 is rotated by a certain angle in the clockwise direction of the state shown in fig. 11 by external vibration or the like, the torsion spring 25 ' enters a compressed state, and the torsion spring 25 ' applies a moment in the counterclockwise direction of fig. 11 to the rotating member 23, forcing the rotating member 23 to return to the position shown in fig. 11 again, whereby it can be seen that the torsion spring 25 ' can maintain the sealing member 21 in the escape state.

It will be appreciated that in another embodiment, the torsion spring 25 'and the sealing member 21 may be disposed on the same side of the rotating member 23 along the second rotation center O'.

The dial 41 drives the lever 22 to rotate around the rotation center line L1, the sliding contact portion 221 rotates around the rotation center line L1 to drive the rotation member 23 to rotate around the second rotation center O ', and the rotation member 23 drives the seal member 21 to rotate around the second rotation center O', so that the seal member 21 is switched between the sealing position and the escape position.

The second torque W4 is in the counterclockwise direction of fig. 14.

It will be appreciated that in another embodiment, the torsion spring 25 'and the sealing member 21 may be disposed on opposite sides of the rotation member 23 along the second rotation center O'.

The guide surface 26a guides the movement of the seal member 21, and prevents the seal member 21 from being deflected or rotated.

In the present embodiment, the guide portion 26 is provided on the mount base 31. It will be appreciated that in embodiments where the mount 31 is not provided, the guide 26 may be provided directly on the cover 30.

Under the condition that the sealing member 21 is at the sealing position, please refer to fig. 17, the switching portion 234 abuts against the inner wall of the head end of the second sliding groove 21b along the extending direction, that is, the switching portion 234 is at the first limit position, and the switching portion 234 can not slide in the second sliding groove 21b along the same direction any more; referring to fig. 18, under the condition that the sealing member 21 is at the avoiding position, the adapting portion 234 abuts against the inner wall of the end of the second sliding groove 21b in the extending direction, that is, the adapting portion 234 is at the second limit position, and the adapting portion 234 cannot slide in the second sliding groove 21b in the same direction any more.

In order to stably hold the seal member 21 at the retracted position, when the rotation center line L1, the adapter 232, and the compression spring 25 ″ are located in the same plane under the condition that the seal member 21 is at the retracted position, the compression spring 25 ″ applies an urging force to the rotating member 23 in the direction toward the water discharge hole 110, the rotation center line L1 is located on an extension line of the urging force, the arm of force is 0, the compression spring 25 ″ cannot apply a moment to the rotating member 23, and the rotating member 23 is located at the dead angle position.

In order to prevent the rotor 23 from being unbalanced in the event of vibration, i.e. to prevent the rotor 23 from deviating from the line of the compression spring 25 ″ in the event of vibration, in the exemplary embodiment of the present application, see fig. 21, the side of the sliding groove 21b adjacent to the compression spring 25 ″ is recessed in the direction of the compression spring 25 ″ to form a locking recess 21b ', and the adapter 232 engages with the locking recess 21 b' when the sealing element 21 is in the retracted position. Since the locking notch 21 b' can prevent the rotation piece 23 from laterally deflecting, the stability of the rotation piece 23 is increased, so that the rotation piece 23 is stably locked at the escape position. When it is required to switch the sealing member 21 from the retracted position to the sealing position, the torque input from the driving lever 22 to the rotary member 23 needs to overcome the resistance torque of the friction force of the locking notch 21 b' and the rotary member 23 to the rotary member 23, and once the rotary member 23 rotates out of the dead angle position, the compression spring 25 ″ applies the first torque to the rotary member 23, so as to rapidly rotate the sealing member 21 to the sealing position.

Fifth embodiment

The resilient positioning element 25 is a torsion spring 25'. In order to facilitate the torsion spring 25 'to apply the first moment and/or the second moment to the rotating member 23, an abutting portion may be formed on the driving lever 22, or an abutting portion may be formed on one side of the gear structure in the axial direction, and one end of the torsion spring 25' may be connected to the abutting portion. It should be noted that the connection position between the torsion spring 25 'and the abutting portion needs to be eccentric to the rotation center line L1, and the torsion spring 25' can apply a moment to the gear structure to lock the gear structure in the sealing position or the avoiding position.

A third aspect of the embodiments of the present application provides a method for controlling any one of the above-mentioned clothes treating apparatuses, referring to fig. 23, including the steps of:
