In an embodiment, referring to fig. 4 to 6, the rotation axis of the inner tub 10 extends in a horizontal direction, for example, in the case where the laundry treating apparatus 100 is a drum washing machine, the drain opening may circulate 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 may be drained without dead angle.

In an embodiment, referring to fig. 7 to 9, after the lever 321 toggles the limiting component 22 to rotate a first preset angle along a third direction, the lever 321 can be separated from the limiting component 22 when the lever 321 is in an extended state; after the shift lever 321 shifts the limiting assembly 22 to rotate a second preset angle along the fourth direction, the shift lever 321 can be separated from the limiting assembly 22 when the shift lever 321 is in an extended state. So design, even though the driving lever 321 stretches out, the driving lever 321 can not influence the rotation of the inner cylinder 10, can not suppress the inner cylinder 10, and can not influence the sealing performance of the sealing element 21.

In an embodiment, referring to fig. 7 to 10, the limiting assembly 22 includes a dial 221, a first dial 222, a second dial 223, a first limiting portion 224, a second limiting portion 225, and an elastic reset unit 226; the dial 221 has a first rotation center, that is, the dial 221 is capable of rotating about the first rotation center O; the first dial 222 is rotatably connected with the dial 221; the second dial 223 is rotationally connected with the dial 221, that is, the first dial 222 can rotate relative to the dial 221, the second dial 223 can rotate relative to the dial 221, for convenience of description, a rotational connection point of the first dial 222 and the dial 221 is denoted as a first rotational point A1, a rotational connection point of the second dial 223 and the dial 221 is denoted as a second rotational point A2, and the first dial 222 and the second dial 223 are arranged at intervals along the rotational direction of the dial 221; the first limiting part 224 is arranged on one side of the first shifting piece 222, which faces away from the second shifting piece 223; the second limiting part 225 is arranged on one side of the second shifting piece 223, which faces away from the second shifting piece 223; the first shifting piece 222 abuts against one side of the first limiting portion 224 under the action of the elastic reset unit 226; the second shifting member 223 abuts against one side of the second limiting portion 225 under the action of the elastic reset unit 226, specifically, the second shifting member 223 abuts against one side of the second limiting portion 225 facing the first shifting member 222, that is, the first shifting member 222 and the second shifting member 223 are located between the first limiting portion 224 and the second limiting portion 225. In a state in which the shift lever 321 is extended, the shift lever 321 can abut against one side of the first shift piece 222 and/or the second shift piece 223 in the rotational direction of the inner cylinder 10; one end of the driving rod 23, which is far away from the sealing element 21, is fixedly connected with the driving plate 221, and the driving rod 321 can abut against one side of the first driving element 222 and/or the second driving element 223 along the rotation direction of the inner cylinder 10.

Since the inner cylinder 10 rotates, the position of the shift lever 321 is unchanged, and thus the rotation locus of the shift lever 321 on the inner cylinder 10 is a circle I. The limit component 22 moves synchronously with the inner barrel 10, so that the track of the first rotation center O is a circle II. Assuming that the seal 21 is in the sealing position when the limit assembly 22 is in the position shown in fig. 8, the seal 21 is in the let-down position when the limit assembly 22 is in the position shown in fig. 9. When the 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, in this case, the second shifting member 223 is located inside the circle I, and when the shifting lever 321 extends toward the limiting assembly 22, the second shifting member 223 does not contact the shifting lever 321, and the first shifting member 222 has a superposition portion with the circle I. If the inner cylinder 10 rotates clockwise in fig. 8, the shift lever 321 abuts against one side of the first shift member 222 facing the second shift member 223, because one side of the first shift member 222 facing away from the second shift member 223 abuts against the first limiting portion 224, the first shift member 222 cannot rotate freely under the action of the first limiting portion 224, the first shift member 222 drives the shift plate 221 to rotate counterclockwise around the first rotation center O, the first shift member 222 gradually moves away from the circle I, when the limiting assembly 22 rotates with the inner cylinder 10 until the first shift member 222 is separated from the shift lever 321, please refer to fig. 9, that is, the first shift member 222 is located inside the circle I, the shift plate 221 is not forced to rotate any more, the torque of the shift plate 221 to the driving rod 23 disappears, the driving rod 23 cannot drive the seal member 21 to move, that is, the shift plate 221 and the shift lever 321 cannot interfere with the movement of the seal member 21 any more, in this case, the seal member 21 is already at the dodge position or can continue to move to the dodge position under the driving of other reset members. When the inner cylinder 10 rotates to the condition that the deflector rod 321 is abutted against one side, deviating from the first deflector piece 222, of the second deflector piece 223, the deflector rod 321 forces the second deflector piece 223 to rotate anticlockwise around the second rotation point A2, and when the limiting component 22 follows the inner cylinder 10 to continue rotating until the second deflector piece 223 is separated from the deflector rod 321, the second deflector piece 223 is reset under the action of the elastic reset unit 226; the movement process after the inner cylinder 10 rotates for one circle is the same as that above, in the process, even if the deflector rod 321 stretches out, the deflector rod 321 can not influence the rotation of the inner cylinder 10, can not hold down the inner cylinder 10, and can not influence the position of the sealing element 21 in the avoiding position.

When the spacing assembly 22 needs to be switched from the position shown in fig. 9 to the position shown in fig. 8, the inner cylinder 10 is reversed, that is, the inner cylinder 10 rotates in the counterclockwise direction in fig. 9, please refer to fig. 9 first, when the spacing assembly 22 follows the inner cylinder 10 to rotate until the deflector 321 abuts against one side of the second deflector 223 facing the first deflector 222 (the position shown in fig. 9), the second deflector 223 cannot rotate freely under the action of the second spacing portion 225, that is, the second deflector 223 forces the deflector 221 to rotate clockwise around the first rotation center O, that is, at this time, the deflector 221 revolves around the rotation axis of the inner cylinder 10, and also rotates around the first rotation center O, and during the clockwise rotation of the deflector 221 around the first rotation center O, the second deflector 223 gradually moves away from the circle I, and when the spacing assembly 22 rotates along with the inner cylinder 10 until the second deflector 223 is separated from the deflector 321, please refer to fig. 8, that is, the second deflector 223 is located inside the circle I, the second deflector 223 cannot force the deflector 221 to rotate freely under the action of the second spacing portion 225, that the deflector 221 disappears, that the deflector 221 cannot move around the first rotation center O, that is, the deflector 221 can move around the first rotation center O, and the deflector 21 can move around the first rotation center O, and the second deflector 221 can move again, and the sealing member 21 can move under the sealing member 21 can move, and the sealing member 21 can move. When the sealing member 21 can be driven by other resetting members to move continuously, the driving plate 221 can be driven by the driving rod 23 to rotate continuously clockwise by a certain angle by the sealing member 21. In the rotation process of the inner cylinder 10 entering the next circle, when the inner cylinder rotates to the point that the deflector rod 321 is abutted against one side of the first deflector member 222, which is away from the second deflector member 223, the deflector rod 321 forces the first deflector member 222 to rotate clockwise around the first rotation point A1, after the deflector rod 321 passes over the first deflector member 222, the first deflector member 222 is reset under the action of the elastic reset unit 226, and as the second deflector member 223 is not contacted with the deflector rod 321, the deflector rod 321 does not influence the rotation of the inner cylinder 10 and the stability of the sealing member 21 at the sealing position.

When the spacing assembly 22 needs to be switched again from the sealing position shown in fig. 8 to the evasive position shown in fig. 9, the inner barrel 10 is again rotated clockwise in fig. 8, the principle of which has been set forth above and will not be described again.

It should be noted that, if the first dial 222 and the second dial 223 have the overlapping portion with the circle I at a position somewhere in the middle between the position shown in fig. 8 and the position shown in fig. 9, the dial 321 may be directly located between the first dial 222 and the second dial 223 after being extended, and depending on the rotation direction of the inner cylinder 10, if the inner cylinder 10 rotates clockwise as shown in fig. 8 or fig. 9, the dial 321 may force the first dial 222 to drive the dial 221 to rotate counterclockwise, and if the inner cylinder 10 rotates counterclockwise, the dial 321 may force the second dial 223 to drive the dial 221 to rotate clockwise.

If the lever 321 is extended to be located outside the first dial 222 and the second dial 223, that is, the lever 321 is not located between the first dial 222 and the second dial 223. In the case that the inner cylinder 10 rotates counterclockwise in fig. 9, the shift lever 321 abuts against one side of the first shift member 222 away from the second shift member 223, the shift lever 321 forces the first shift member 222 to rotate clockwise around the first rotation point A1, after the shift lever 321 passes over the first shift member 222, the first shift member 222 is reset under the action of the elastic reset unit 226, and the shift lever 321 forces the second shift member 223 to drive the dial 221 to rotate clockwise, and then the position shown in fig. 8 is reached. If the inner cylinder 10 rotates clockwise, when the limit component 22 follows the inner cylinder 10 to rotate until the deflector rod 321 abuts against one side of the second deflector 223, which faces away from the first deflector 222, the second deflector 223 rotates freely around the second rotation point A2, when the deflector rod 321 passes over the second deflector 223, the second deflector 223 resets under the action of the elastic resetting unit 226, and the limit component 22 continues to move according to the inner cylinder 10 until the deflector rod 321 abuts against one side of the first deflector 222, which faces towards the second deflector 223, the first deflector 222 cannot rotate freely, the dial 221 forces the first deflector 222 to drive the dial 221 to rotate anticlockwise around the first rotation center O, and then the position shown in fig. 9 is reached.

It should be noted that the lever 321 may be retracted when appropriate, for example, after one or several rotations of the inner barrel 10, the lever 321 is retracted.

As can be seen from the above, the limiting assembly 22 of the embodiment of the present application can output two torques in opposite directions without holding the inner cylinder 10, and has smart design, simple structure and high reliability.

In an embodiment, referring to fig. 10, the first limiting portion 224 is a first protrusion protruding from the surface of the dial 221; and/or, the second limiting portion 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 it can function to block the rotation of the first dial 222; the first limiting portion 224 and the driving plate 221 may be integrally formed, or may be a split structure and fixedly connected. Similarly, the specific structural form of the second protrusion is not limited, as long as it can block the second dial 223 from rotating; the second limiting portion 225 and the driving plate 221 may be integrally formed, or may be a split structure and fixedly connected.

The specific structure of the elastic restoring unit 226 is not limited, for example, referring to fig. 7 and 10, in an embodiment, the elastic restoring unit 226 is a tension spring, and the tension spring is connected between the first pulling member 222 and the second pulling 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 with the first shifting member 222, and the first shifting member 222 abuts against one side of the first limiting portion 224 under the action of the first torsion spring; the second torsion spring is connected with the second shifting piece 223, and the second shifting piece 223 is abutted against one side of the second limiting part 225 under the action of the second torsion spring.

In the process that the driving plate 221 assembly follows the inner cylinder 10 to rotate, the driving plate 221 always faces one side of the driving plate 321, that is, the disc surface of the driving plate 221 rotates in the same plane, under the condition that the position of the driving plate 321 is unchanged, the first driving piece 222 (or the second driving piece 223) can have a certain contact time with the driving plate 321, and in the process that the inner cylinder 10 drives the driving plate 221 to rotate, the driving plate 321 can be gradually separated from the first driving piece 222 (or the second driving piece 223).

In one embodiment, referring to fig. 5 and 6, the laundry treating apparatus 100 includes a cover 60. The cover 60 is open to one side of the drain opening, the cover 60 and the inner cylinder 10 together enclose a receiving chamber, a part of the sealing member 21 and the driving rod 23 is located in the receiving chamber, and one end of the driving rod 23 away from the sealing member 21 extends out of the receiving chamber. That is, one end of the driving lever 23 is located outside the accommodation chamber. The cover 60 provides the installation space for the sealing member 21 and the driving lever 23, so that the sealing member 21 and the driving lever 23 and the like do not interfere with the outer tub 40 and other structures during the rotation of the inner tub 10, and the gap between the inner tub 10 and the outer tub 40 can be reduced, so that the structure of the laundry treating apparatus 100 is more compact. And simultaneously, the sealing element 21 and the driving rod 23 are protected, and the reliability of the drainage structure 20 is improved.

The drain structure 20 may seal the drain port and the escape drain port from the outside of the inner tube 10, and may be switched between a sealing position and an escape position as needed.
