In one embodiment, referring to fig. 2 and 3, the drain driving structure 30 includes a sealing ring 35. The sealing ring 35 is fixedly disposed on the peripheral wall of the extension hole, and the shift lever 321 is sealingly inserted into the sealing ring 35.

Referring to fig. 4 to 9, in another aspect, a clothes treating apparatus 100 is provided, where the clothes treating apparatus 100 includes an inner drum 10, an outer drum 40, a box 50, a drainage structure 20, and a drainage driving structure 30 in any one of the above embodiments.

The drain driving structure 30 is disposed in the accommodating space 100a, and the driving rod 321 can extend into the outer tub 40 through the mounting hole 40 a.

The inner barrel 10 is isolated from the outer barrel 40, the inner barrel 10 is not only used for containing clothes, beating or stirring clothes, but also used for containing water, the inner barrel 10 can also be called as a non-porous inner barrel 10, and the problem that in the prior art, dirt is easily stored and contained in the outer barrel 40 due to the fact that the outer barrel 40 is used for containing water can be avoided. In order to allow the lever 321 to move the drain structure 20, a mounting hole 40a is formed at one axial side of the outer tub 40, and the lever 321 extends into the outer tub 40 through the mounting hole 40 a. Since the drain driving structure 30 is disposed in the accommodating space 100a, the drain driving structure 30 is prevented from occupying a space between the outer tub 40 and the inner tub 10, so that the space between the inner tub 10 and the outer tub 40 is minimized to make the structure of the laundry treating apparatus 100 compact. The drainage driving structure 30 is disposed outside the outer tub 40, and is convenient for isolating the inner tub 10 from the drainage driving structure 30 through the outer tub 40, which is beneficial to prevent the drainage driving structure 30 from contacting the water discharged from the inner tub 10 too much.

In one embodiment, referring to fig. 7 to 10, the drainage structure 20 includes a sealing member 21, a limiting member 22 and a driving rod 23.

In a state where the shift lever 321 extends toward the stopper assembly 22, the shift lever 321 can selectively shift the stopper assembly 22 to rotate around the first rotation center in a third direction or a fourth direction to drive the sealing member 21 to switch between a sealing position for sealing the drain opening and an avoiding position for avoiding the drain opening, and the third direction is opposite to the fourth direction.

The limiting component 22 can be selectively shifted to rotate around the first rotation center along the third direction or the fourth direction by the same shifting lever 321, for example, the third direction is a counterclockwise direction, and the fourth direction is a clockwise direction, which is simple in structure and convenient to operate.

It can be understood that, the driving lever 321 drives the limiting component 22 to rotate around the first rotation center, which means that the limiting component 22 rotates along with the inner cylinder 10 during the rotation of the inner cylinder 10, and after the driving lever 321 extends out, the driving lever 321 remains stationary, and there is a relative motion between the limiting component 22 and the driving lever 321, so that the driving lever 321 can drive the driving plate 221 component to rotate.

In one embodiment, referring to fig. 4 to 6, the inner cylinder 10 has a rotation axis, and the water outlet is formed in a rotation circumferential direction of the inner cylinder 10, so that water in the inner cylinder 10 is thrown out of the water outlet by centrifugal force during the dehydration process of the inner cylinder 10; the limiting component 22 is disposed on the outer side of the inner cylinder 10 along the rotation axis direction, and one end of the driving rod 23 away from the sealing component 21 protrudes out of the outer side of the inner cylinder 10 along the rotation axis direction. That is, the extending direction of the driving rod 23 is substantially parallel to the direction of the rotation axis of the inner cylinder 10, and the limiting assembly 22 rotates along with the inner cylinder 10, that is, the limiting assembly 22 rotates substantially in the plane perpendicular to the rotation axis.

It should be noted that the rotation axis of the inner cylinder 10 may extend in the horizontal direction, may also extend in the vertical direction, and may also extend in an inclined direction between the horizontal direction and the vertical direction, which is not limited herein.

In one embodiment, referring to fig. 4-6, the rotation axis of the inner tub 10 extends along a horizontal direction, for example, in the case that the laundry treating apparatus 100 is a drum washing machine, the water outlet can be circulated through the lowest point of the rotation track of the inner tub 10 during the rotation of the inner tub 10, so that the water in the inner tub 10 can be emptied without dead angles.

In an embodiment, referring to fig. 7 to 9, after the driving lever 321 drives the limiting assembly 22 to rotate by a first predetermined angle along the third direction, the driving lever 321 can be separated from the limiting assembly 22 when the driving lever 321 is in the extended state; after the shifting lever 321 shifts the limiting assembly 22 to rotate by the second preset angle along the fourth direction, the shifting lever 321 can be separated from the limiting assembly 22 in the extended state of the shifting lever 321. By the design, even if the shifting lever 321 extends out, the shifting lever 321 cannot influence the rotation of the inner barrel 10, the inner barrel 10 cannot be locked, and the sealing performance of the sealing element 21 cannot be influenced.

In an embodiment, referring to fig. 7 to 10, the position-limiting assembly 22 includes a dial 221, a first dial 222, a second dial 223, a first position-limiting portion 224, a second position-limiting portion 225, and an elastic reset unit 226; the dial 221 has a first rotation center, that is, the dial 221 is rotatable about the first rotation center O; the first dial 222 is rotationally connected with the dial 221; the second dial 223 is rotationally connected with the dial 221, that is, the first dial 222 is able to rotate relative to the dial 221, and the second dial 223 is able to rotate relative to the dial 221, for convenience of description, a rotational connection point of the first dial 222 and the dial 221 is referred to as a first rotational point a1, a rotational connection point of the second dial 223 and the dial 221 is referred to as a second rotational point a2, and the first dial 222 and the second dial 223 are disposed at intervals along a rotational direction of the dial 221; the first position-limiting part 224 is disposed on a side of the first toggle piece 222 away from the second toggle piece 223; the second limiting part 225 is arranged on one side of the second shifting piece 223 departing from the second shifting piece 223; the first toggle piece 222 abuts against one side of the first limit part 224 under the action of the elastic reset unit 226; the second toggle member 223 abuts against one side of the second limiting portion 225 under the action of the elastic reset unit 226, specifically, the second toggle member 223 abuts against one side of the second limiting portion 225 facing the first toggle member 222, that is, the first toggle member 222 and the second toggle member 223 are located between the first limiting portion 224 and the second limiting portion 225. In the state that the shift lever 321 is extended, the shift lever 321 can abut against one side of the first toggle piece 222 and/or the second toggle piece 223 along the rotation direction of the inner cylinder 10; the end of the driving rod 23 away from the sealing member 21 is fixedly connected to the dial 221, and the shift rod 321 can abut against one side of the first dial 222 and/or the second dial 223 along the rotation direction of the inner barrel 10.

Since the inner cylinder 10 rotates, the position of the lever 321 is not changed, and thus, the rotation locus of the lever 321 on the inner cylinder 10 is a circle I. Since the limiting assembly 22 follows the inner cylinder 10 to move synchronously, the trajectory of the first rotation center O is a circle pi. It is assumed that the sealing member 21 is in the sealing position when the stop assembly 22 is in the position shown in fig. 8 and that the sealing member 21 is in the clearance position when the stop assembly 22 is in the position shown in fig. 9. When the position-limiting assembly 22 needs to be switched from the position shown in fig. 8 to the position shown in fig. 9, please refer to fig. 8 first, in this case, the second toggle member 223 is located inside the circle I, when the toggle rod 321 extends toward the position-limiting assembly 22, the second toggle member 223 does not contact with the toggle rod 321, and the first toggle member 222 has an overlapping portion with the circle I. If the inner cylinder 10 is rotated in the clockwise direction of fig. 8, the shift lever 321 abuts on a side of the first toggle member 222 facing the second toggle member 223, because one side of the first shifting piece 222 departing from the second shifting piece 223 abuts against the first limit portion 224, the first shifting piece 222 cannot rotate freely under the action of the first limit portion 224, the first shifting piece 222 drives the dial 221 to rotate counterclockwise around the first rotation center O, the first shifting piece 222 gradually leaves away from the circle I, when the position-limiting assembly 22 rotates with the inner cylinder 10 until the first shifting element 222 is separated from the shifting lever 321, please refer to fig. 9, i.e., the first dial 222 is located inside the circle I, the first dial 222 no longer forces the dial 221 to rotate, the torque of the dial 221 on the drive rod 23 disappears, the drive rod 23 does not drive the seal 21 to move, that is, the dial 221 and the lever 321 no longer interfere with the movement of the seal 21, in which case, the sealing element 21 is already in the retracted position or can be moved further into the retracted position by a further restoring element. When the inner cylinder 10 rotates until the shifting lever 321 abuts against one side of the second shifting piece 223 departing from the first shifting piece 222, the shifting lever 321 forces the second shifting piece 223 to rotate counterclockwise around the second rotation point a2, and when the limiting assembly 22 continues to rotate along with the inner cylinder 10 until the second shifting piece 223 is separated from the shifting lever 321, the second shifting piece 223 is reset under the action of the elastic resetting unit 226; the movement process after the inner cylinder 10 rotates for one circle is the same as the above, and in the process, even if the shift lever 321 extends out, the shift lever 321 does not influence the rotation of the inner cylinder 10, the inner cylinder 10 is not locked, and the avoiding position of the sealing element 21 is not influenced.

When the position-limiting assembly 22 needs to be switched from the position shown in fig. 9 to the position shown in fig. 8, the inner cylinder 10 rotates reversely, that is, the inner cylinder 10 rotates in the counterclockwise direction of fig. 9, please refer to fig. 9 first, when the position-limiting assembly 22 rotates along with the inner cylinder 10 until the shift rod 321 abuts against one side of the second shift member 223 facing the first shift member 222 (the position shown in fig. 9), the second shift member 223 cannot rotate freely under the action of the second limiting portion 225, the second shift member 223 forces the dial 221 to rotate clockwise around the first rotation center O, that is, the dial 221 rotates both around the rotation axis of the inner cylinder 10 and around the first rotation center O, during the clockwise rotation of the dial 221 around the first rotation center O, the second shift member 223 gradually moves away from the circle I, when the position-limiting assembly 22 rotates along with the inner cylinder 10 until the second shift member 223 disengages from the shift rod 321, please refer to fig. 8, that the second shift member 223 is located inside the circle I, the second toggle member 223 no longer forces the dial 221 to rotate, the torque of the dial 221 on the drive rod 23 disappears, the drive rod 23 does not drive the seal 21 to move, that is, the dial 221 and the toggle rod 321 no longer interfere with the movement of the seal 21, in which case the seal 21 is already in the sealing position or can continue to move to the sealing position under the drive of the other reset member. 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 221 to continue to rotate clockwise by a certain angle through the driving rod 23. In the rotating process that the inner cylinder 10 enters the next circle, when the inner cylinder rotates to the side, which is away from the second toggle piece 223, of the toggle rod 321 and the first toggle piece 222, to abut against, the toggle rod 321 forces the first toggle piece 222 to rotate clockwise around the first rotating point a1, after the toggle rod 321 crosses the first toggle piece 222, the first toggle piece 222 resets under the action of the elastic resetting unit 226, because the second toggle piece 223 does not contact with the toggle rod 321, so the toggle rod 321 does not influence the rotation of the inner cylinder 10, and the stability of the sealing member 21 at the sealing position is not influenced.

When the limiting assembly 22 needs to be switched from the sealing position shown in fig. 8 to the avoiding position shown in fig. 9 again, the inner barrel 10 rotates in the clockwise direction of fig. 8 again, and the principle is stated above and is not described again.

It should be noted that if the shift lever 321 extends to be located between the first dial 222 and the second dial 223 at a position somewhere in the middle between the position shown in fig. 8 and the position shown in fig. 9, namely, when the first dial 222 and the second dial 223 both have an overlapped portion with the circle I, the shift lever 321 will force the first dial 222 to drive the dial 221 to rotate counterclockwise if the inner cylinder 10 rotates clockwise as shown in fig. 8 or 9, and the shift lever 321 will force the second dial 223 to drive the dial 221 to rotate clockwise if the inner cylinder 10 rotates counterclockwise, depending on the rotation direction of the inner cylinder 10.

If the shift lever 321 is extended to be located outside the first toggle member 222 and the second toggle member 223, that is, the shift lever 321 is not located between the first toggle member 222 and the second toggle member 223. Under the condition that the inner cylinder 10 rotates counterclockwise in fig. 9, the shift lever 321 abuts against a side of the first dial 222 away from the second dial 223, the shift lever 321 forces the first dial 222 to rotate clockwise around the first rotation point a1, after the shift lever 321 passes over the first dial 222, the first dial 222 is reset under the action of the elastic reset unit 226, and the shift lever 321 further forces the second dial 223 to drive the dial 221 to rotate clockwise, and then reaches the position shown in fig. 8. If the inner cylinder 10 rotates clockwise, when the limiting component 22 rotates along with the inner cylinder 10 until the shifting lever 321 abuts against one side of the second shifting piece 223 departing from the first shifting piece 222, the second shifting piece 223 rotates freely around the second rotation point a2, when the shifting lever 321 passes over the second shifting piece 223, the second shifting piece 223 resets under the action of the elastic resetting unit 226, when the limiting component 22 moves continuously according to the inner cylinder 10 until the shifting lever 321 abuts against one side of the first shifting piece 222 facing the second shifting piece 223, the first shifting piece 222 cannot rotate freely, and the shifting piece 221 forces the first shifting piece 222 to drive the shifting piece 221 to rotate around the first rotation center O in the counterclockwise direction, and then the position shown in fig. 9 is reached.

It should be noted that the rod 321 can be retracted when appropriate, for example, after one or more rotations of the inner cylinder 10, the rod 321 is retracted.

From the above, the limiting component 22 of the embodiment of the present application can output two torques in opposite directions without locking the inner cylinder 10, and has the advantages of ingenious concept, simple structure and high reliability.

In an embodiment, referring to fig. 10, the first position-limiting portion 224 is a first protrusion protruding from the surface of the dial 221; and/or the second limiting part 225 is a second protrusion protruding from the surface of the dial 221. The specific structural form of the first protrusion is not limited as long as the first poking member 222 can be prevented from rotating; the first position-limiting portion 224 and the dial 221 may be integrally formed, or may be separate and fixedly connected. Similarly, the specific structural form of the second protrusion is not limited as long as the second toggle member 223 can be prevented from rotating; the second limiting portion 225 and the dial 221 may be integrally formed, or may be separate and fixedly connected.

For example, referring to fig. 7 and 10, in one embodiment, the elastic reset unit 226 is a tension spring connected between the first toggle member 222 and the second toggle member 223. In another embodiment, the elastic reset unit 226 includes a first torsion spring and a second torsion spring, wherein the first torsion spring is connected to the first toggle member 222, and the first toggle member 222 abuts against one side of the first position-limiting portion 224 under the action of the first torsion spring; the second torsion spring is connected to the second toggle member 223, and the second toggle member 223 abuts against one side of the second limiting portion 225 under the action of the second torsion spring.

During the rotation of the dial 221 assembly along with the inner cylinder 10, the dial 221 always faces one side of the shift lever 321, that is, the dial face of the dial 221 rotates in the same plane, under the condition that the position of the shift lever 321 is unchanged, the first dial piece 222 (or the second dial piece 223) can have a certain contact time with the shift lever 321, and during the rotation of the dial 221 driven by the inner cylinder 10, the shift lever 321 can gradually separate from the first dial piece 222 (or the second dial piece 223).

In one embodiment, referring to fig. 5 and 6, the laundry treating apparatus 100 includes a housing 60. The cover 60 is open on the side facing the outlet, the cover 60 and the inner barrel 10 together enclose an accommodating chamber in which the sealing member 21 and part of the drive rod 23 are located, and the end of the drive rod 23 remote from the sealing member 21 extends out of the accommodating chamber. That is, one end of the driving rod 23 is located outside the accommodating chamber. The cover 60 provides an installation space for the sealing member 21 and the driving rod 23, so that the sealing member 21, the driving rod 23 and other structures do not interfere with the outer tub 40 and other structures during the rotation of the inner tub 10, the gap between the inner tub 10 and the outer tub 40 can be reduced, and the structure of the laundry treatment apparatus 100 is more compact. Meanwhile, the sealing member 21 and the driving rod 23 are protected, and the reliability of the drainage structure 20 is improved.

The drain structure 20 may be configured such that the drain port and the escape port are sealed from the outside of the inner tube 10, and the sealed position and the escape position can be switched as needed.

In one embodiment, referring to fig. 5 and 6, the cover 60 is a lifting rib. During the process of washing the clothes by the clothes treatment device 100, on one hand, the lifting ribs rotate together with the clothes, and after the clothes are lifted to a certain height, the clothes fall into the 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 present application, the existing structure of the laundry processing apparatus 100 is fully utilized, the space inside the lifting rib is fully utilized, and the laundry washing capacity of the inner drum 10 is not reduced.
