The problem of easy storage of dirt and dirt caused by the water contained in the outer tub 12; the inner tub 11 is formed with a drainage hole 11a (refer to FIG. 4 ).

8 , 9 , 17 and 18 , the drain valve assembly 3 includes a valve core 31 , an elastic positioning member, an elastic restoring member, and a transmission rod mechanism 32 connected to the inner cylinder 11 , that is, the transmission rod mechanism 32 will follow the inner The drum 11 is rotated. 10 and FIG. 20 , the transmission rod mechanism 32 has a rotation centerline L, that is, the transmission rod mechanism 32 revolves around the rotation axis of the inner cylinder 11 while rotating around the rotation centerline L.

The valve body 31 has a sealing position (see FIG. 2 ) for sealing the drainage hole 11 a, and a drainage position (see FIG. 4 ) for opening the drainage hole 11 a.

The first end of the transmission rod mechanism 32 drives the valve core 31 to move. During the rotation of the inner cylinder 11 , the driving device 20 can selectively toggle the second end of the transmission rod mechanism 32 to drive the transmission rod mechanism 32 around the rotation centerline L Rotationally, that is, the drive device 20 provides the power source for the transmission lever mechanism 32 .

The elastic positioning member can maintain the valve core 31 in the sealing position or the draining position, that is, when the valve core is in the sealing position, the valve core 31 can maintain the sealing position under the action of the elastic positioning member, and when the valve core is in the draining position , the valve core 31 can be maintained at the drain position under the action of the elastic positioning member. The elastic restoring member can at least drive the second end of the transmission rod mechanism 32 to restore. In the washing process, or in other situations where drainage is not required, please refer to 2 and FIG. 3, the valve core 31 is in the sealing position, the drain hole 11a is blocked by the valve core 31, and the water in the inner cylinder 11 will not flow into the inner cylinder 11. 4, the valve core 31 is switched from the sealing position to the draining position, the drain hole 11a is opened, and the water in the inner cylinder 11 is discharged from the inner cylinder 11 through the drain hole 11a.

In the clothes treating apparatus of the embodiment of the present application, no matter what the rotational speed of the inner cylinder 11 is, as long as the transmission rod mechanism 32 can be rotated, the valve core 31 can be switched between the sealing position and the draining position. The reliability is high, and the service life of the drain valve assembly 3 can be effectively increased. Furthermore, at least the second end of the transmission rod mechanism 32 is driven to reset by the elastic reset member, so that it is convenient for the driving device 20 to toggle the second end of the transmission rod mechanism 32 at the same position.

It should be noted that the restoration of the second end of the transmission rod mechanism 32 refers to that the second end of the transmission rod mechanism 32 returns to the initial position before being toggled by the driving device 20 .

It should be noted that, the laundry treatment device drains water through the drain hole 11a during or after washing, and the laundry treatment device can also drain water through the drain hole 11a during the dehydration process.

In one embodiment, the valve core 31 also has an intermediate critical position between the sealing position and the draining position. It should be noted that the said intermediate critical position between the sealing position and the draining position refers to that, on the movement stroke of the valve core 31, the intermediate critical position is between the sealing position and the draining position, that is to say, When the valve core 31 passes through the intermediate critical position in the process of moving from the sealing position to the draining position, the valve core 31 also passes through the intermediate critical position in the process of moving from the draining position to the sealing position.

When the transmission rod mechanism 32 drives the valve core 31 to cross the intermediate critical position, the elastic positioning member can drive the valve core 31 to continue to move to the sealing position or the draining position. Specifically, when the valve core 31 moves from the sealing position to the drain position and crosses the intermediate critical position, the elastic positioning member can drive the valve core 31 to continue to move to the drain position, that is, after the valve core 31 crosses the intermediate critical position, even if The transmission rod mechanism 32 stops driving the valve core 31, and the valve core 31 can also continue to move to the drainage position under the action of the elastic positioning member.

When the transmission rod mechanism 32 drives the valve core 31 to move beyond the intermediate critical position, the elastic reset member can at least drive the second end of the transmission rod mechanism 32 to idle and reset. Since the elastic positioning member can drive the valve core 31 to continue to move to the sealing position or the drainage position, as long as the transmission rod mechanism 32 drives the valve core 31 to cross the intermediate critical position, if the driving device 20 stops driving the transmission rod mechanism 32, the transmission rod mechanism At least the second end of the 32 can be idling and reset under the action of the elastic reset member. In this way, when the driving device 20 needs to toggle the transmission rod mechanism 32 next time, the driving device 20 will toggle the first position of the transmission rod mechanism 32 at the same position. In this way, the driving and matching structure of the transmission rod mechanism 32 and the driving device 20 can be simplified.

It should be noted that the idling refers to that the transmission rod mechanism 32 will not form a driving force to the valve core 31 during the idling process.

In order to facilitate the support and installation of the inner tub 11, please refer to FIG. 1 to FIG. 4. In one embodiment, the laundry treatment device includes an outer tub 12, the inner tub 11 is rotatably arranged in the outer tub 12, and the outer tub 12 is opposite to the inner tub. 11 acts as a support. The clothes treating apparatus may drain water through the outer tub 12, specifically, the water discharged from the drain hole 11a enters the outer tub 12, and the outer tub 12 concentrates the water to be discharged out of the clothes treating apparatus.

The drainage holes 11a may be provided at suitable positions in the inner cylinder 11 as long as the water in the inner cylinder 11 can be drained through the drainage holes 11a. The number and specific shape of the drainage holes 11a are not limited.

The first lever 322 is connected to the second end of the transmission rod 321 , and the driving device 20 selectively toggles the first lever 322 . Specifically, after the driving device 20 toggles the first lever 322, since the transmission lever mechanism 32 rotates with the inner cylinder 11, the first lever 322 rotates under the joint action of the driving device 20 and the inner cylinder 11, and the first lever 322 rotates The lever 322 drives the transmission rod 321 to rotate synchronously.

In this embodiment, the movement of the valve core 31 is translation, so that the side of the valve core 31 used to close the drain hole 11a always faces the drain hole 11a. When the valve core 31 is switched from the drain position to the sealing position, the valve core 31 The side used to close the drain hole 11a can be directly or indirectly pressed against the periphery of the drain hole 11a smoothly and reliably, which can greatly improve the sealing reliability of the drain hole 11a, and the sealing effect is better.

The connection method of the first lever 322 and the transmission rod 321 is not limited, as long as the two can achieve synchronous movement, for example, they can be integrally formed, snap-connected, screwed, etc., which are not limited here.

It can be understood that, in order to facilitate the connection between the first lever 322 and the transmission lever 321, in some embodiments, please refer to FIG. 8 and FIG. 17, the first lever 322 includes a fixedly connected rod portion 3221 and a cylindrical portion 3222, which drives the The device 20 is in contact with the rod part 3221 , one end of the rod part 3221 is connected to the cylinder part 3222 , and the cylinder part 3222 is sleeved on the second end of the transmission rod 321 .

It should be noted that the rotation direction of the transmission lever mechanism 32 is related to the rotation direction of the inner cylinder 11. For example, when the inner cylinder 11 rotates clockwise in FIG. 5, if the driving device 20 turns the first lever 322, Then, the first lever 322 can only drive the transmission lever mechanism 32 to rotate counterclockwise around the rotation center line L as shown in FIG. 5 .

At this time, the transmission rod mechanism 32 will not drive the valve core 31 to move, and the valve core 31 can still be maintained at the current sealing position. , so that the reliability of the laundry treatment device can be improved. When the inner cylinder 11 is reversed and the driving device 20 moves the first lever 322, the first end of the transmission lever 321 biases the first driving surface 3231b, forcing the reversing mechanism 323 to rotate counterclockwise in FIG. 14 .
