Detailed Description

It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application.

In the description of the embodiments of the present application, "up", "down", "left", "right", orientation or positional relationship is based on the orientation or positional relationship shown in fig. 1, it being understood that these orientation terms are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be considered as limiting the present application.

Referring to fig. 1 to 3, the drum assembly of the laundry appliance includes a washing tub 3, a sealing valve 10, a fixing seat 20 and a driving mechanism 30. Wherein, the washing tub 3 can hold water and is provided with the outlet 3a, that is to say, when the clothes treatment equipment is in the process of washing clothes, the washing water is held in the washing tub 3, this washing tub 3 also can be called as the aporate inner tube, can avoid the problem of the easy dirty and dirty collection that leads to through outer tub flourishing water among the prior art. The sealing valve 10 is used for closing the water discharge opening 3a, and specifically, the sealing valve 10 closes the water discharge opening 3a during the washing of the laundry in the washing tub 3, so that the inside of the washing tub 3 can contain water.

The fixing seat 20 is connected with the washing tub 3 to rotate along with the washing tub 3, and the driving mechanism 30 is connected with the fixing seat 20, that is, in the rotating process of the washing tub 3, the fixing seat 20 and the driving mechanism 30 can also rotate along with the washing tub 3.

The driving mechanism 30 comprises a mass body 31, a gear transmission system 33 and an elastic resetting member 32, the mass body 31 and the sealing valve 10 are in transmission connection through the gear transmission system 33, the mass body 31 moves along the radial direction of the washing tub 3 under the action of centrifugal force, so as to drive the sealing valve 10 to open the water outlet 3a through the gear transmission system 33. The sealing valve 10 can be returned to the sealing position closing the drain port 3a by the elastic returning member 32. That is, the mass body 31 and the elastic restoring member 32 jointly drive the sealing valve 10 to switch between the drainage position (refer to fig. 2) that opens the drainage port 3a and the sealing position (refer to fig. 1) that closes the drainage port 3 a.

In the cylinder assembly of the embodiment of the present application, the mass body 31 drives the sealing valve 10 to move under the action of the centrifugal force, and no matter the washing tub 3 rotates to any position, the centrifugal force of the mass body 31 is enough to open the sealing valve 10, so that the drainage port 3a can be opened without rotating the washing tub 3 to a precise position, and the drainage reliability of the washing tub 3 is high; in addition, without power-on and wiring, the connection of the driving mechanism 30 with the washing tub 3 is facilitated; moreover, the transmission of the movement between the mass body 31 and the sealing valve 10 is simple and reliable by means of the gear transmission system 33.

Specifically, the default position of the sealing valve 10 is the sealing position, and when the rotation speed of the washing tub 3 does not exceed the preset value, the centrifugal force of the mass body 31 is not sufficient to drive the sealing valve 10 to move, and the sealing valve 10 is maintained at the sealing position. When the rotation speed of the washing tub 3 exceeds the preset value, the mass body 31 moves in the radial direction of the washing tub 3 under the centrifugal force and drives the gear train 33 to switch the sealing valve 10 from the sealing position shown in fig. 1 to the drainage position shown in fig. 2.

When the rotation speed of the washing tub 3 is reduced to not more than the preset value, the centrifugal force of the mass body 31 is small enough not to overcome the elastic force of the elastic restoring member 32, and the elastic force of the elastic restoring member 32 drives the sealing valve 10 to restore from the drainage position shown in fig. 2 to the sealing position shown in fig. 1. It should be noted that, during the resetting process of the sealing valve 10, the mass body 31 is also reset by the gear transmission system 33.

The number of the drain ports 3a is not limited, and may be one, or two or more. The position of the drain opening 3a may be at the closed end of the washing tub 3 in the axial direction, or at the sidewall of the washing tub 3 in the circumferential direction.

The axis of rotation of the washing tub 3 may be in the horizontal direction, i.e. a drum-type washing tub; the axis of rotation of the washing tub 3 may also be in the vertical direction, for example, a pulsator type washing tub; the axis of rotation of the washing tub 3 may also be an inclined direction between the horizontal direction and the vertical direction, for example, a stirring type washing tub.

The sealing valve 10, the driving mechanism 30 and the fixing seat 20 may be all disposed in the washing tub 3, or may be all disposed outside the washing tub 3, which is not limited herein.

For example, in an embodiment, referring to fig. 1 and fig. 6, the barrel assembly includes a lifting rib 4 disposed in the washing tub 3, a mounting cavity 3b is formed between the lifting rib 4 and a part of the inner wall of the washing tub 3, the water outlet 3a is located on the corresponding inner wall of the mounting cavity 3b, and the sealing valve 10, the driving mechanism 30 and the fixing seat 20 are disposed in the mounting cavity 3 b. In the process of washing clothes by the clothes treatment equipment, the lifting ribs 4 carry the clothes to rotate together, and the clothes are lifted to a certain height and then fall into water again under the action of self gravity to generate the stick beating and falling effects, so that the washing effect is achieved. In this embodiment, on the one hand, the sealing valve 10, the driving mechanism 30 and the fixing seat 20 do not interfere with the rotation of the washing tub 3, and on the other hand, the existing structure of the laundry treatment apparatus is fully utilized, the space inside the lifting rib 4 is fully utilized, the laundry washing capacity of the washing tub 3 is not reduced, and no additional installation space is required, so that the structure of the drum assembly is compact.

In some embodiments, the movement path of the sealing valve 10 may be a straight line, and in other embodiments, the movement path of the sealing valve 10 may also be a curved line.

In some embodiments, the sealing valve 10 can reciprocate in the axial direction of the washing tub 3, and in other embodiments, the sealing valve 10 can also reciprocate in the radial direction of the washing tub 3.

For example, in an embodiment, referring to fig. 1 and fig. 6, the drainage port 3a is disposed on a circumferential sidewall of the washing tub 3, and the mass body 31 and the sealing valve 10 both linearly reciprocate along a radial direction of the washing tub 3, and the movement directions of the two are parallel and opposite. In this embodiment, the power transmission of the gear transmission system 33 does not need to be steered vertically, which is beneficial to the structural arrangement of the gear transmission system 33, and the driving mechanism 30 can be more compact in structure and occupy less space.

The specific configuration of the gear train 33 is not limited. For example, referring to fig. 1 and 5, in an embodiment, the gear transmission system 33 includes a first rack 331, a second rack 333, and at least one gear 332 engaged between the first rack 331 and the second rack 333, and the gear 332 is rotatably connected to the fixing base 20, that is, the gear 332 rotates around the rotation connection. The first toothed rack 331 is arranged on the sealing valve 10, i.e. the first toothed rack 331 moves synchronously with the sealing valve 10. The second rack 333 is provided on the mass body 31, that is, the second rack 333 moves in synchronization with the mass body 31. In this way, the first rack 331, the second rack 333, and the gear 332 can achieve the linear reverse movement of the mass body 31 and the sealing valve 10, and the sealing valve has a simple structure and requires a small installation space. It should be noted that the opposite movement means that the movement directions of the mass body 31 and the sealing valve 10 are opposite.

It should be noted that the gear train 33 may be a two-stage transmission or a more-stage transmission as long as the linear opposite movement of the mass body 31 and the sealing valve 10 can be realized. Illustratively, in one embodiment, the gear train 33 is a two-stage transmission, the meshing transmission between the first rack 331 and one gear 332 is a one-stage transmission, and the transmission between the gear 332 and the second rack 333 is a two-stage transmission, and vice versa.

The sealing valve 10 is switched from the sealing position shown in fig. 1 to the drainage position shown in fig. 2 as an example. When the mass body 31 moves in the radial outward direction of the washing tub 3 under the action of the centrifugal force, the lower direction in fig. 1 is the radial outward direction, the second rack 333 moves in the downward direction in fig. 1 in synchronization with the movement of the mass body 31, the second rack 333 drives the gear 332 to rotate counterclockwise, the gear 332 rotates to drive the first rack 331 to move in the radial inward direction of the washing tub 3, that is, in the upward direction shown in fig. 1, and the sealing valve 10 moves in the radial inward direction of the washing tub 3 in synchronization with the first rack 331, so that the sealing valve 10 can be switched from the sealing position shown in fig. 1 to the water discharging position shown in fig. 2.

In one embodiment, the first rack 331 and the sealing valve 10 are integrally formed; in another embodiment, the first rack 331 and the sealing valve 10 are separate and fixedly connected together, for example, by screws, bolts, welding, etc.

In one embodiment, the second rack 333 and the mass body 31 are integrally formed; in another embodiment, the second rack 333 and the mass body 31 are of a split structure and are fixedly connected together, for example, by screws, bolts, welding, and the like.

The number of gear trains 33 is not limited and may be, for example, one or more sets. In the embodiment where the number of gear trains 33 is multiple, the multiple gear trains 33 are uniformly spaced along the circumference of the sealing valve 10 to balance the lateral forces generated by the gear trains 33 and avoid lateral deflection of the sealing valve 10 during movement.

It should be noted that the lateral direction in the embodiment of the present application refers to any side perpendicular to the movement direction of the sealing valve.

Exemplarily, in the present embodiment, the number of the gear trains 33 is two, and the two gear trains 33 are symmetrically arranged along the circumferential direction of the sealing valve 10, that is, the two gear trains 33 are arranged along a straight line.

The specific structural form of the sealing valve 10 is not limited, and in an exemplary embodiment, referring to fig. 9, the sealing valve 10 includes a valve plate 101 and a valve column 102, wherein a first rack 331 is disposed on a surface of the valve column 102 and extends along a length direction of the valve column 102. The valve plate 101 is used for sealing the water outlet 3a, and the valve column 102 is used for facilitating the connection of the sealing valve 10 and the first rack 331 and can also play a guiding role.

The valve sheet 101 and the valve column 102 are fixedly connected by, for example, screw fastening, bonding, integral molding, or the like.

The fixing seat 20 further comprises a guide post 23 arranged in the shell 21, the spring is sleeved on the guide post 23, and the guide post 23 plays a role in installing and limiting the spring. When the sealing valve 10 is in the drainage position, the guide post 23 projects into the accommodation chamber 102a, so that space can be saved.

In an embodiment, referring to fig. 9, the sealing valve 10 includes a positioning protrusion 1022 protruding from the surface of the spool 102, referring to fig. 11, a limiting hole 22c extending along the sliding direction of the spool 102 is formed on the guide wall 22, and the positioning protrusion 1022 extends into the limiting hole 22c and can slide in the limiting hole 22 c. The positioning protrusion 1022 and the limiting hole 22c are engaged with each other, so that on one hand, a guiding movement of the sealing valve 10 can be performed, and on the other hand, an assembly is also facilitated, specifically, during the assembly process, the spool 102 is pressed against the spring, and meanwhile, the positioning protrusion 1022 is also inserted into the limiting hole 22c, at this time, the sealing valve 10 is released, the spring is still in a compressed state, the spool 102 moves in a direction away from the spring under the action of the spring until the positioning protrusion 1022 comes into contact with a sidewall stop of the limiting hole 22c, and therefore, the spool 102 cannot be separated from the fixing seat 20 under the action of the spring, and a pre-positioning of the spool 102 is achieved. If there is no engagement between the positioning protrusion 1022 and the position-limiting hole 22c, the operator needs to hold the spool 102 all the time during the assembly process, otherwise the spool 102 will be ejected out of the holder 20 by the spring.

In one embodiment, the movement stroke of the sealing valve 10 is equal to the extension length of the limiting hole 22 c. That is, the drainage position and the sealing position of the sealing valve 10 are determined by the cooperation of the positioning projection 1022 and the stopper hole 22 c.

In an embodiment, the extension length of the limiting hole 22c is greater than the movement stroke of the sealing valve 10, and when the sealing valve 10 is in the sealing position, referring to fig. 1, the mass body 31 abuts against one end of the housing 21 away from the water outlet 3 a. When the sealing valve 10 is in the drainage position, referring to fig. 2, an end of the spool 102 away from the sealing valve 10 abuts an end of the housing 21 away from the drainage port 3 a. That is, in this embodiment, the fitting of the positioning projection 1022 and the stopper hole 22c does not determine the drainage position or the sealing position of the sealing valve 10.

In one embodiment, referring to fig. 1 to 3, the cylinder assembly further includes a flexible sealing element 40, the flexible sealing element 40 is connected to the fixing base 20 and jointly encloses a sealing cavity 40a, the valve plate 101, the valve column 102 and the driving mechanism 30 are all disposed in the sealing cavity 40a, the valve plate 101 is connected to the flexible sealing element 40, and the valve column 102 is connected to the gear transmission system 33. Since the valve plate 101, the valve column 102 and the driving mechanism 30 are all arranged in the sealing cavity 40a, the valve plate, the valve column 102 and the driving mechanism 30 are not contacted with the washing water, on one hand, the flock in the washing water cannot enter the sealing cavity 40a, so that the flock and other impurities are prevented from being blocked or wound on the driving mechanism 30 and the sealing valve 10, the normal movement of the sealing valve 10 and the driving mechanism 30 can be ensured, and the working reliability and the service life of the sealing valve 10 are improved; on the other hand, in the case where the drive mechanism 30 or the sealing valve 10 is made of a metal material, the corrosive action of the washing water on the metal material can be avoided.

The particular configuration of the flexible seal 40 is not limited.

In an exemplary embodiment, referring to fig. 12 to 14, the flexible sealing member 40 includes a first flange 41, a telescopic tube 42 and a sealing abutting structure 43, the telescopic tube 42 can be extended and retracted along its length direction, and the telescopic tube 42 can be extended and retracted to accommodate the reciprocating motion of the sealing valve 10; opposite ends of the extension tube 42 in the length direction are open, the sealing abutting structure 43 closes a first end of the extension tube 42, the valve plate 101 is connected with the sealing abutting structure 43, and the first flange 41 protrudes out of the circumferential surface of a second end of the extension tube 42 and is connected with one end of the housing 21 facing the water outlet 3a in a sealing manner. The first flange 41 is configured to enable the flexible sealing element 40 to have a large installation contact area with the fixed seat 20, so as to improve the connection reliability of the flexible sealing element 40 with the fixed seat 20.

It should be noted that the flexible sealing member 40 may be an integrally formed structure to improve the structural reliability of the flexible sealing member 40. The material of the flexible sealing member 40 is not limited, and includes, but is not limited to, silicone, rubber, etc.

The flexible sealing member 40 is required to reliably seal the water discharge opening 3a in the sealing position and also reliably avoid the water discharge opening 3a in the drainage position, so as to avoid a large movement force acting on the sealing valve 10, thereby improving the movement reliability of the sealing valve 10. To this end, in an embodiment of the present application, the bellows 42 is a bellows that accommodates movement of the sealing valve 10 by expansion or folding of the bellows itself without significant resistance to elastic deformation of the bellows itself.

In one embodiment, when the sealing valve 10 is in the sealing position and the bellows is in the natural state, referring to fig. 13 and 14, the included angle θ of the recess inside the bellows is in the range of 65 ° to 85 °. It should be noted that the natural state refers to a state in which the bellows is neither compressed nor stretched. The bellows does not exert a resistance on the sealing valve 10 throughout the movement of the sealing abutment structure 43 towards the drain opening 3a driven by the sealing valve 10. The bellows is compressed during the movement of the sealing valve 10 driving the seal abutment structure 43 away from the drain opening 3 a. The range of the included angle theta of the depressions enables the corrugated pipe to have a suitable number of wrinkles. Specifically, the corrugated pipe is formed by arranging a plurality of folds along the length direction, and if the included angle θ of the concave part is smaller than the minimum value of the included angle range, the number of the folds of the corrugated pipe is obviously increased under the same installation space, so that the weight of the corrugated pipe is increased, and the compression resistance is also increased. If the included angle θ of the recess is larger than the maximum value of the above-mentioned included angle range, the number of folds of the bellows is significantly reduced in the same installation space, which may result in poor compression stability of the bellows, which may be twisted laterally, and in addition, the sealing abutting structure 43 needs to be away from the water discharge opening 3a for water discharge to avoid affecting the water discharge flow rate, so that, in order to make the sealing abutting structure 43 have a large movement stroke, the bellows may be elastically straightened during the movement of the sealing valve 10 driving the sealing abutting structure 43 toward the water discharge opening 3a, which may generate a large resistance to the movement of the sealing valve 10.

In one embodiment, referring to fig. 12-14, the sealing structure 43 includes a support end plate 431 and a sealing lip 432, wherein the support end plate 431 closes the first end of the bellows 42. Referring to fig. 1 to fig. 3, the valve sheet 101 is stacked on the surface of the support end plate 431, that is, the valve sheet 101 and the support end plate 431 are closely attached to each other in a face-to-face manner, and the sealing lip 432 is disposed on a side of the support end plate 431 facing away from the valve sheet 101. Referring to fig. 1 and fig. 3, when the sealing valve 10 is in the sealing position, the valve plate 101 abuts the sealing lip 432 around the water outlet 3 a. That is, in this embodiment, the sealing of the drain opening 3a is achieved by the sealing lip 432. The configuration of the seal lip 432 can reduce the requirement for flatness of the structure around the drain opening 3a, and the contact area between the seal lip 432 and the surface of the washing tub 3 is small, so that the seal lip 432 can be sealed around the drain opening 3a well even if the structure around the drain opening 3a is not flat.

In an embodiment, referring to fig. 13 and 14, the inner side of the supporting end plate 431 has a ring groove 431a, and the edge of the valve plate 101 is clamped into the ring groove 431 a. During assembly, the support end plate 431 is forced to be elastically deformed in the process that the valve plate 101 is clamped into the ring groove 431a, and after the valve plate 101 is clamped into the ring groove 431a, the support end plate 431 is wrapped on the edge of the valve plate 101 under the action of self elastic restoring force, so that the valve plate 101 and the support end plate 431 can be quickly connected.

In one embodiment, referring to fig. 14, the supporting end plate 431 is provided with a mounting hole 431b penetrating through the supporting end plate 431. Referring to fig. 1 and 2, the sealing valve 10 includes an inverted buckle 103 protruding from the valve plate 101 toward the drain opening 3a, and the inverted buckle 103 sealingly passes through the installation hole 431b and abuts against the structure around the installation hole 431 b. The structural form of the reverse buckle 103 can also realize the quick and reliable connection between the support end plate 431 and the valve plate 101. Specifically, during assembly, the reverse buckle 103 penetrates through the installation hole 431b from the side of the seal cavity 40a, the installation hole 431b is propped open by the reverse buckle 103 in the process of penetrating through the installation hole 431b, after the reverse buckle 103 penetrates through the installation hole 431b, the support end plate 431 tightly abuts against a connecting structure between the reverse buckle 103 and the valve plate 101 under the action of self elastic restoring force, and the structural form of the reverse buckle 103 can prevent the valve plate 101 from being separated from the support end plate 431, so that the connection reliability between the seal valve 10 and the support end plate 431 is improved.

It should be noted that, in an embodiment, please refer to fig. 3, the connection between the valve plate 101 and the supporting end plate 431 is realized only by the cooperation between the valve plate 101 and the ring groove 431 a; in another embodiment, the connection between the valve plate 101 and the support end plate 431 is realized only by the matching of the reverse buckle 103 and the mounting hole 431 b; in another embodiment, referring to fig. 1, the valve sheet 101 is connected to the supporting end plate 431 by the cooperation of the valve sheet 101 and the ring groove 431a and the cooperation of the inverse buckle 103 and the installation hole 431 b.

The specific manner of forming the annular groove 431a on the support end plate 431 is not limited, and for example, in an embodiment, the edge of the support end plate 431 may further include a flange bent toward the tube side of the extension tube 42, and the annular groove 431a may be formed on the folded inner side.
