Detailed Description

It should be noted that, in the case of no conflict, the embodiments of the present application and the technical features of the embodiments may be combined with each other, and the detailed description in the specific embodiments should be interpreted as an explanation of the gist of the present application and should not be construed as unduly limiting the present application.

In the description of the embodiments of the present application, the terms "upper," "lower," "left," "right," orientation or positional relationship are based on the orientation or positional relationship shown in fig. 1, and it should be understood that these orientation terms are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present application.

Referring to fig. 1 to 3, a drum assembly of a laundry device according to an embodiment of the present application includes a tub 3, a sealing valve 10, a fixing base 20, and a driving mechanism 30. Wherein, the washing tub 3 can hold water and is provided with a water outlet 3a, that is, when the laundry treatment apparatus is in the process of washing laundry, the washing water is held in the washing tub 3, and the washing tub 3 can also be called a non-porous inner tub, so that the problem of easy dirt collection caused by the water holding of the outer tub in the prior art can be avoided. The sealing valve 10 is used to close the drain port 3a, and in particular, the sealing valve 10 closes the drain port 3a during washing of laundry in the washing tub 3, so that water can be contained in the washing tub 3.

The fixing base 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 base 20, that is, the fixing base 20 and the driving mechanism 30 rotate along with the washing tub 3 during the rotation of the washing tub 3.

The driving mechanism 30 includes a mass body 31, a gear train 33, and an elastic restoring member 32, the mass body 31 is in driving connection with the sealing valve 10 through the gear train 33, and the mass body 31 moves in the radial direction of the washing tub 3 under the action of centrifugal force to drive the sealing valve 10 to open the drain port 3a through the gear train 33. The sealing valve 10 can be returned to the sealing position closing the drain port 3a by the elastic return member 32. That is, the mass body 31 and the elastic restoring member 32 drive the sealing valve 10 in combination to switch between a drainage position (see fig. 2) where the drain port 3a is opened and a sealing position (see fig. 1) where the drain port 3a is closed.

According to the barrel assembly provided by the embodiment of the application, the sealing valve 10 is driven to move by the mass body 31 under the action of centrifugal force, no matter the washing barrel 3 rotates to any position, only the centrifugal force of the mass body 31 is enough to open the sealing valve 10, so that the water outlet 3a can be opened without rotating the washing barrel 3 to an accurate position, and the drainage reliability of the washing barrel 3 is high; in addition, the connection of the driving mechanism 30 and the washing tub 3 is facilitated without the need of switching on a power supply and arranging electric wires; further, the transmission of the motion between the mass body 31 and the sealing valve 10 is performed by the gear train 33, and the transmission is simple and reliable.

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

When the rotational speed of the washing tub 3 is reduced to not more than a preset value, the centrifugal force of the mass body 31 is small enough 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. During the resetting process, the sealing valve 10 also drives the mass body 31 to be reset through the gear transmission system 33.

The number of the water discharge openings 3a is not limited, and may be one or two or more. The drain port 3a may be located at the closed end of the tub 3 in the axial direction or may be located at the sidewall of the tub 3 in the circumferential direction.

The rotation axis of the tub 3 may be in a horizontal direction, i.e., a drum-type tub; the rotation axis of the washing tub 3 may be in a vertical direction, for example, a pulsator type washing tub; the rotation axis of the washing tub 3 may also be an oblique 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 base 20 may be disposed in the washing tub 3, or may be disposed outside the washing tub 3, and are not limited thereto.

In an exemplary embodiment, referring to fig. 1 and 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 portion of the inner wall of the washing tub 3, the water outlet 3a is located on the inner wall corresponding to the mounting cavity 3b, and the sealing valve 10, the driving mechanism 30 and the fixing base 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 after the clothes are lifted to a certain height, the clothes are dropped into water again under the action of self gravity to generate a stick-beating and drop-dropping effect, 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 base 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 capacity of the washing tub 3 for washing laundry is not reduced, and additional other installation space is not required, so that the structure of the drum assembly is compact.

In some embodiments, the motion trajectory of the sealing valve 10 may be a straight line, and in other embodiments, the motion trajectory of the sealing valve 10 may be a curved line.

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

In an exemplary embodiment, referring to fig. 1 and 6, the drain port 3a is provided on a sidewall of the washing tub 3 in a circumferential direction, and the mass body 31 and the sealing valve 10 are linearly reciprocated in a radial direction of the washing tub 3 in parallel and opposite directions. In this embodiment, the power transmission of the gear train 33 does not need to be vertically turned, which is advantageous for the structural arrangement of the gear train 33, and can make the driving mechanism 30 more compact and occupy less space.

The specific structural form of the gear train 33 is not limited. For example, referring to fig. 1 and 5, in one embodiment, the gear 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, wherein the gear 332 is rotatably connected to the fixed base 20, that is, the gear 332 rotates around the rotational connection. The first rack 331 is provided on the sealing valve 10, i.e., the first rack 331 moves in synchronization with the sealing valve 10. The second rack 333 is disposed on the mass body 31, that is, the second rack 333 moves synchronously with the mass body 31. In this way, through the structural forms of the first rack 331, the second rack 333 and the gear 332, the mass body 31 and the sealing valve 10 can move along the straight line in the opposite direction, and the structure is simple, and the required installation space is small. The reverse movement means that the movement direction of the mass body 31 and the sealing valve 10 is opposite.

The gear train 33 may be a two-stage transmission or a multi-stage transmission, as long as the mass body 31 and the sealing valve 10 can move in a linear reverse direction. Illustratively, in one embodiment, the gear train 33 is a two-stage drive, the meshed drive between the first rack 331 and one gear 332 is a one-stage drive, and the drive between the gear 332 and the second rack 333 is a two-stage drive, and vice versa.

The sealing valve 10 is described by taking as an example the switching from the sealing position shown in fig. 1 to the drainage position shown in fig. 2. When the mass body 31 moves in the radial outward direction of the washing tub 3 under the action of centrifugal force, the lower part in fig. 1 is in the radial outward direction, the second rack 333 moves in the radial outward direction of the washing tub 3 synchronously with the mass body 31, the second rack 333 drives the gear 332 to rotate counterclockwise, and the gear 332 drives the first rack 331 to move in the radial inward direction of the washing tub 3, that is, move in the upper direction shown in fig. 1, and the sealing valve 10 moves in the radial inward direction of the washing tub 3 synchronously with the first rack 331, so that the sealing valve 10 can be switched from the sealing position shown in fig. 1 to the drainage 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 is formed as a separate structure and is fixedly connected to the sealing valve 10, for example, by screws, bolts, welding, or the like.

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 in a split structure and are fixedly connected together, for example, by means of screws, bolts, welding, etc.

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

Illustratively, in the embodiment of the present application, the number of gear trains 33 is two, and the two sets of gear trains 33 are symmetrically arranged along the circumferential direction of the sealing valve 10, i.e., the two sets of gear trains 33 are arranged along a straight line.

The specific structure 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 spool 102, wherein a first rack 331 is disposed on a surface of the spool 102 and extends along a length direction of the spool 102. The valve plate 101 is used for sealing the water outlet 3a, and the valve column 102 is convenient for connecting the sealing valve 10 with the first rack 331 and can also play a guiding role.

The manner of fixing the valve plate 101 to the spool 102 is not limited, and may be, for example, screw fastening, adhesion, integral molding, or the like.

In one embodiment, referring to fig. 8, the mass body 31 has a through hole 31a, the spool 102 is disposed through the through hole 31a, and the second rack 333 is fixedly disposed on an inner wall of the through hole 31 a. That is, the mass body 31 is an integral structure provided around the spool 102, so that the mass body 31 can have a larger mass, occupy a smaller installation space, and can make the movement of the mass body 31 smoother.

The outer contour shape of the mass body 31 is not limited, and may be circular, elliptical, polygonal, or the like. In one embodiment of the present application, the outer contour of the mass body 31 is circular in shape.

The guide wall 22 provides an installation position for the gear 332, so that the interference between the mass body 31 and the gear 332 in the moving process is avoided, and in addition, the guide wall 22 plays a good guide role for the movement of the valve column 102, so that the valve column 102 is prevented from deflecting transversely; further, the guide wall 22 effectively blocks the spool 102 from the mass body 31, preventing the spool 102 from colliding with the mass body 31.

In one embodiment, the end of the casing 21 facing away from the drain opening 3a is a closed end, and the end of the guide wall 22 is fixedly connected to the closed end of the casing 21, for example, integrally formed, clamped, bonded, or the like.

The circumferential profile of the mass body 31 may be adapted to the sliding channel, and the specific shape of the two is not limited, for example, in an embodiment, the circumferential profile of the mass body 31 is circular, and the projection of the sliding channel in a plane perpendicular to the moving direction of the mass body 31 is also circular.

Without the engagement of the locating boss 1022 and the stop aperture 22c, the operator would need to hold the spool 102 all the time during assembly, otherwise the spool 102 would be sprung out of the seat 20.

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 protrusion 1022 and the limiting hole 22 c.

In one 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 facing away from the drain port 3 a. When the sealing valve 10 is in the drainage position, referring to fig. 2, the end of the spool 102 away from the sealing valve 10 abuts against the end of the housing 21 away from the drain port 3 a. That is, in this embodiment, the engagement of the positioning projection 1022 and the limiting aperture 22c does not determine the drainage position or the sealing position of the sealing valve 10.

In an embodiment, referring to fig. 1 to 3, the barrel assembly further includes a flexible sealing member 40, the flexible sealing member 40 is connected with the fixing base 20 and encloses a sealing cavity 40a together, 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 with the flexible sealing member 40, and the valve column 102 is connected with the gear transmission system 33. Because the valve plate 101, the valve column 102 and the driving mechanism 30 are arranged in the sealing cavity 40a, the valve plate is not contacted with the washing water, on one hand, the filings in the washing water can not enter the sealing cavity 40a, the filings 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, when 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 specific structural form of the flexible seal member 40 is not limited.

Illustratively, in one embodiment, referring to fig. 12-14, the flexible seal member 40 includes a first flange 41, a bellows 42, and a seal abutment 43, the bellows 42 being capable of telescoping along its length to accommodate reciprocation of the sealing valve 10 by telescoping of the bellows 42; the opposite ends of the telescopic tube 42 in the length direction are open, the sealing abutting structure 43 closes the first end of the telescopic tube 42, the valve plate 101 is connected with the sealing abutting structure 43, and the first flange 41 protrudes from the circumferential surface of the second end of the telescopic tube 42 and is connected with one end of the housing 21 facing the drain port 3a in a sealing manner. The structural form of the first flange 41 can enable the flexible sealing element 40 to have a larger installation contact area with the fixed seat 20, and the connection reliability of the flexible sealing element 40 and the fixed seat 20 is improved.

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 seal 40 is not limited, and includes, for example, but is not limited to, silicone, rubber, and the like.

The flexible seal 40 is required to reliably seal the drain port 3a in the sealing position and reliably avoid the drain port 3a in the draining position, and to avoid a large movement force on the sealing valve 10, so as to improve the movement reliability of the sealing valve 10. To this end, in one embodiment of the application, the bellows 42 is a bellows that accommodates movement of the sealing valve 10 by stretching or collapsing the bellows itself without itself having significant resistance to elastic deformation.

In one embodiment, when the sealing valve 10 is in the sealing position, the bellows is in a natural state, and referring to fig. 13 and 14, the included angle θ of the recess in the bellows is 65 ° to 85 °. The natural state refers to a state in which the bellows is neither compressed nor stretched. The bellows does not apply resistance to the sealing valve 10 throughout the process of driving the sealing abutment structure 43 toward the drain port 3a by the sealing valve 10. The bellows is compressed as the sealing valve 10 drives the sealing abutment 43 away from the drain opening 3 a. The range of the included angle theta of the concave parts enables the corrugated pipe to have a proper number of folds. Specifically, the corrugated tube is formed by arranging a plurality of folds along the length direction, if the included angle theta of the concave part is smaller than the minimum value of the included angle range, the number of the folds of the corrugated tube can be obviously increased under the same installation space, so that the weight of the corrugated tube can be increased, and the compression resistance can be increased. If the included angle θ of the recess is larger than the maximum value of the above 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, the bellows may be laterally twisted, and in addition, the seal abutting structure 43 needs to be spaced from the drain port 3a during drainage to avoid affecting drainage flow, so that the seal abutting structure 43 has a larger movement stroke, and the bellows may be elastically straightened during the movement of the seal abutting structure 43 toward the drain port 3a driven by the seal valve 10, which may generate a larger resistance to the movement of the seal valve 10.

In one embodiment, referring to fig. 12 to 14, the sealing abutment structure 43 includes a support end plate 431 and a sealing lip 432, the support end plate 431 closing the first end of the telescopic tube 42. Referring to fig. 1 to 3, the valve plate 101 is stacked on the surface of the support end plate 431, that is, the valve plate 101 and the support end plate 431 are closely attached face to face, and the sealing lip 432 is disposed on the side of the support end plate 431 facing away from the valve plate 101. Referring to fig. 1 and 3, when the sealing valve 10 is in the sealing position, the valve plate 101 abuts the sealing lip 432 around the drain opening 3 a. That is, in this embodiment, the sealing of the drain port 3a is achieved by the sealing lip 432. The structural form of the sealing lip 432 can reduce the requirement on the flatness of the structure around the drain port 3a, the contact area between the sealing lip 432 and the surface of the washing tub 3 is small, and even if the structure around the drain port 3a is not too flat, the sealing lip 432 can seal around the drain port 3a well.

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

In one embodiment, referring to fig. 14, the support end plate 431 is provided with a mounting hole 431b penetrating the support end plate 431. Referring to fig. 1 and 2, the sealing valve 10 includes a back-off 103 protruding from a side of the valve plate 101 facing the drain port 3a, and the back-off 103 passes through the mounting hole 431b in a sealing manner and abuts on a structure around the mounting hole 431b. The structure of the back-off 103 can also realize quick and reliable connection of the support end plate 431 and the valve plate 101. Specifically, during assembly, the back-off 103 passes through the mounting hole 431b from one side of the sealing cavity 40a, in the process of passing through the mounting hole 431b, the mounting hole 431b is propped open by the back-off 103, after the back-off 103 passes through the mounting hole 431b, the supporting end plate 431 is tightly abutted to a connecting structure between the back-off 103 and the valve plate 101 under the action of self elastic restoring force, the structural form of the back-off 103 can prevent the valve plate 101 from separating from the supporting end plate 431, and the connection reliability of the sealing valve 10 and the supporting end plate 431 is improved.

It should be noted that, in an embodiment, referring to fig. 3, the valve plate 101 is connected to the support end plate 431 only by the cooperation of the valve plate 101 and the annular groove 431 a; in another embodiment, the valve plate 101 is connected to the support end plate 431 only by the cooperation of the back-off 103 and the mounting hole 431 b; in still another embodiment, referring to fig. 1, the valve plate 101 is connected to the support end plate 431 by matching the valve plate 101 with the ring groove 431a and matching the back-off 103 with the mounting hole 431b.

The specific manner of forming the annular groove 431a in the support end plate 431 is not limited, and for example, in one embodiment, the edge of the support end plate 431 may have a flange that is bent toward the tube side of the telescopic tube 42, and the annular groove 431a may be formed inside the folded flange.
