The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example one

As shown in fig. 1 to 10, the present embodiment provides a centrifugal drainage device and a washing machine, wherein the centrifugal drainage device is installed at the bottom of an inner tub of the washing machine, and can open or close a drainage port 101 on the inner tub, thereby controlling drainage of the inner tub.

The centrifugal drainage device described in this embodiment specifically includes:

the mounting bracket (500) is mounted,

a valve plug 200 relatively movably mounted on the mounting bracket 500;

and a driving part for moving the valve plug 200.

The driving part includes:

a centrifugal slider 300 which slides under the action of centrifugal force;

and a reversing transmission mechanism connecting the valve plug 200 and the centrifugal slider 300 and used for converting the sliding of the centrifugal slider 300 in one direction into the movement of the valve plug 200 in the other direction.

The mounting bracket 500 includes:

the base (510) is provided with a base,

and a coupling frame 520 for coupling the base 510 and the valve plug 200.

The perpendicular projection of the extension direction of the connecting bracket 520 on the plane on which the eccentric slider 300 slides coincides with the perpendicular projection of the extension direction of the reversing gear mechanism on the plane on which the eccentric slider 300 slides.

In this embodiment, the centrifugal slider 300 drives the valve plug 200 to move through a reversing transmission mechanism, and the reversing transmission mechanism can convert the movement of the centrifugal slider 300 in the horizontal direction into the movement of the valve plug 200 in the vertical direction. When the centrifugal slider 300 horizontally slides along the radial direction of the inner barrel, as shown in fig. 1 to 7, the valve plug 200 vertically moves in a direction parallel to the central axis of the inner barrel to open/close the drain port 101, so that the drain port 101 can be disposed on the bottom 100 of the inner barrel, and the drain port 101 directly drains downward when opened, resulting in higher drainage efficiency.

The connecting frame 520 and the reversing transmission mechanism of the mounting bracket 500 are located below the water outlet 101, and in this embodiment, through the structural design of the centrifugal drainage device, the extending directions of the connecting frame 520 and the reversing transmission mechanism are overlapped on the plane where the centrifugal slider 300 slides, that is, the vertical projection on the horizontal plane in the drawing, so that the occupation of the area below the water outlet 101 can be reduced. When the washing machine drains water, the condition that the water outlet 101 is blocked by a large area is avoided, thereby ensuring higher drainage efficiency. On the other hand, the washing machine drain may carry a large amount of lint, which may be caught to remain at any position through which the drain water flows. The extension directions of the connecting frame 520 and the reversing transmission mechanism are provided with coincident projections on the horizontal plane, and the area exposed in the drainage water flow can be reduced, so that the hooking residue of the thread scraps is reduced, and the phenomenon of water leakage caused by the fact that the drainage efficiency is reduced due to the hooking of the thread scraps or the phenomenon that the centrifugal drainage device acts to seal the inner barrel is avoided.

In this embodiment, in order to realize the movements of the centrifugal slider 300 and the plug 200 in different directions, the reversing transmission mechanism specifically includes:

the left end of the connecting rod 420 is connected to the centrifugal slider 300 and moves along with the centrifugal slider 300;

one end of the reversing rod 410 is hinged to the right end of the connecting rod 420, and is driven by the connecting rod 420 to move in the same direction as the centrifugal slider 300, and the other end of the reversing rod 410 is hinged to the valve plug 200 to drive the valve plug 200 to move in the other direction.

A perpendicular projection of the extending direction of the link frame 520 on the plane on which the centrifugal slider 300 slides coincides with a perpendicular projection of the extending direction of the link rod 420 on the plane on which the centrifugal slider 300 slides.

In the preferred embodiment, the extending direction of the connecting rod 420 is parallel to the sliding direction of the centrifugal slider 300, i.e. the connecting rod 420 and the connecting frame 520 both extend along the radial direction of the bottom 100 of the inner barrel. The above-mentioned manner can ensure that the acting force applied to the reversing lever 410 by the connecting rod 420 does not have a component along the circumferential direction of the barrel bottom 100, thereby reducing the component of the acting force applied to the valve plug 200 in the horizontal direction and reducing the frictional resistance applied to the valve plug 200 when moving relative to the mounting bracket 500.

In this embodiment, the centrifugal slider 300 horizontally slides leftward under the action of centrifugal force, and the connecting rod 420 drives one end of the reversing rod 410 to synchronously move leftward with the centrifugal slider 300. The other end of the reversing lever 410 swings about its one end hinged to the connecting lever 420, thereby moving the valve plug 200 upward in the vertical direction in the mounting bracket 500.

In detail, the right end of the connecting rod 420 has a connecting groove in which the lower end of the reversing lever 410 is disposed to be hinged to the connecting rod 420.

In a further aspect of this embodiment, the connecting frame 520 includes:

a guide 521 for mounting the valve plug 200;

and a connection part 522 for connecting the base 510 and the guide part 521.

Here, a perpendicular projection of the extending direction of the connecting portion 522 on the plane on which the centrifugal slider 300 slides coincides with a perpendicular projection of the extending direction of the connecting rod 420 on the plane on which the centrifugal slider 300 slides.

Further, the connecting rod 420 extends from the centrifugal slider 300 to the reversing rod 410 from outside to inside along the radial direction of the barrel bottom 100, so that the distance between the centrifugal slider 300 and the central axis of the inner barrel bottom 100 is greater than the distance between the valve plug 200 and the central axis, i.e. the centrifugal slider 300 has a larger rotation radius. Such a centrifugal slider 300 may provide greater centrifugal force

In this embodiment, the connection portion 522 is disposed above the connection rod 420 and extends in the same direction, thereby forming an overlapped structure to reduce the obstruction of the drain opening 101 when installed in the washing machine, and the structure is simple.

In a preferred embodiment of the present invention, the upper surface of the connecting portion 522 is an inwardly concave curved surface with a height gradually decreasing from the two ends to the middle.

In this embodiment, the valve plug 200 seals the water outlet 101 from the inner barrel, and for better sealing effect, the part of the barrel bottom 100 located at the periphery of the water outlet 101 protrudes below the barrel bottom 100 to be matched with the valve plug 200. The guide 521 is positioned corresponding to the drain opening 101, and the base 510 is used for fixing the mounting bracket 500 and is disposed on the periphery of the drain opening 101 such that the connection 522 extends from the periphery of the drain opening 101 to a position close to the center of the drain opening 101, and the middle area of the connection 522 passes through an area protruding downward on the tub bottom 100. The upper surface of the connecting part 522 is set to be the concave curved surface with the height gradually reduced from two ends to the middle part, so that the downward convex area on the barrel bottom 100 can be effectively avoided, the mounting bracket 500 can be mounted closer to the barrel bottom 100, and the structure is more compact.

In a further aspect of this embodiment, the lower surface of the connecting portion 522 is provided with a groove 5221 extending in the same direction as the connecting rod 420, and the connecting rod 420 is partially disposed in the groove 5221. Above-mentioned setting mode can make connecting portion 522 and connecting rod 420 be closer in vertical direction, with the compacter of centrifugal drainage device's overall structure design, reduces its whole volume, and then can reduce the occupation to interior bucket below space when being applied to in the washing machine, is favorable to the dilatation of interior bucket.

In this embodiment, the base 510 specifically includes:

two fixing parts 511 which are arranged at intervals and are respectively positioned at two sides of the guide part 521 and used for fixing the base 510;

a transition part 512 for connecting the two fixing parts 511.

The connecting portion 522 has two ends connected to the transition portion 512 and the guide portion 521, respectively.

In this embodiment, the fixing portion 511 of the base 510 is connected to a structure below the inner barrel, so as to fix the mounting bracket 500 relative to the inner barrel, and the guiding portion 521 is suspended relative to the fixing portion 511. The two fixing portions 511 are preferably symmetrical with respect to the guide portion 521, so that the fixing effect on the mounting bracket 500 is better and the structure is more firm.

In a further aspect of this embodiment, the guiding portion 521 has a hollow slideway extending vertically, and a side of the transition portion 512 facing the guiding portion 521 has an arc-shaped edge, and a center of the arc-shaped edge is located on an axis of the hollow slideway. The radius corresponding to the arc-shaped edge is larger than that of the water outlet 101, so that the transition part 512 can avoid the area below the water outlet 101, and the transition part 512 is prevented from blocking the drainage water flow to influence the drainage efficiency.

The valve plug 200 in this embodiment specifically includes a sealing cap 201 and a supporting rod 202, the sealing cap 201 is used for sealing/opening the water outlet 101, and two ends of the supporting rod 202 are respectively connected to the sealing cap 201 and the reversing rod 410. Specifically, the lower end of the supporting rod 202 is slidably disposed in the hollow slide way of the guiding portion 521, and is hinged to the reversing rod 410, and the upper end of the supporting rod 202 extends out of the guiding portion 521 and is fixedly connected to the sealing cover 201.

Further, the right side of the guide portion 521 is provided with an avoiding groove 5211 which extends vertically and has an open lower end, and when the reversing rod 410 swings to drive the supporting rod 202 to move, the lower half portion of the reversing rod 410 passes through the avoiding groove 5211 and extends out of the guide portion 521 when the sealing cover 201 seals the water outlet 101. The lower end of the support bar 202 has an open mounting groove, and the upper end of the reversing bar 410 is inserted into the mounting groove to be hinged with the support bar 202.

Preferably, a sealing gasket 203 is fixedly arranged on the lower side of the periphery of the sealing cover 201, and when the valve plug 200 seals the drainage opening 101, the sealing gasket 203 is in sealing fit with the periphery of the drainage opening 101 on the inner side of the bucket bottom 100, so that a better sealing effect is achieved.

Because the sealing cover 201 is positioned in the inner barrel and seals the water outlet 101 from top to bottom, when water is contained in the inner barrel, the water pressure acts on the upper surface of the sealing cover 201 to provide auxiliary sealing force, and the sealing effect is better. The guide 521 may limit the movement of the support bar 202 in the horizontal direction, thereby effectively converting the horizontal movement of the centrifugal slider 300 into a movement that drives the valve plug 200 in the vertical direction by the reversing lever 410.

For the pulsator washing machine, due to the limitation of the highest rotational speed that can be achieved, in order to provide a centrifugal force sufficient to open the drain port 101 through the centrifugal slider 300, it is necessary to increase the mass of the centrifugal slider 300, that is, to require a centrifugal slider 300 having a larger volume. In this embodiment, the centrifugal slider 300 has a plate-shaped structure, and can be attached to the bottom 100 of the inner tub as much as possible when being applied to a washing machine, so that the volume can be increased by increasing the tiled area of the inner tub when the excessive space below the inner tub is not occupied, and the centrifugal slider has a larger mass, thereby improving the centrifugal force which can be provided by the centrifugal slider.

Specifically, the centrifugal slider 300 in this embodiment has a certain length along the circumferential extension of the inner barrel, and the mass of the centrifugal slider 300 can be effectively increased by increasing the length of the centrifugal slider 300 along the circumferential extension of the inner barrel.

The washing machine provided by the embodiment comprises an inner barrel, wherein a water outlet 101 is formed in the bottom 100 of the inner barrel. The washing machine also comprises the centrifugal drainage device.

In the washing/rinsing process, the valve plug 200 blocks the water outlet 101, so that the inner barrel independently holds water.

During the draining process, the centrifugal slider 300 slides from inside to outside along the radial direction of the inner barrel under the action of centrifugal force, and the reversing transmission mechanism drives the valve plug 200 to move along the direction parallel to the central axis of the inner barrel to open the draining port 101.

In this embodiment, at least the region lower than the highest water level of the washing machine is not provided with dewatering holes on the wall of the inner barrel, and the water outlet 101 is blocked by the valve plug 200 to form a closed inner barrel in the washing/rinsing process, so that the inner barrel can independently contain water in the washing/rinsing process. The washing machine is not provided with an outer barrel, only the water collecting device is arranged below the inner barrel, and the height of the upper edge of the water collecting device is lower than that of the barrel opening of the inner barrel, so that the capacity expansion of the inner barrel is realized.

The centrifugal drainage device can be directly arranged on the bottom 100 of the inner barrel or arranged on a flange 700 fixedly connected below the bottom 100 of the inner barrel. The valve plug 200 corresponds to the position of the drain port 101, and thus, the opening and closing of the drain port 101 can be controlled.

During the washing/rinsing process, the inner barrel is in a free state, and the valve plug 200 blocks the water outlet 101. When water is drained, the inner barrel is controlled to rotate at a certain rotating speed, so that enough centrifugal force is generated to enable the centrifugal slider 300 to slide, the centrifugal slider 300 slides outwards along the radial direction of the barrel bottom 100 under the action of the centrifugal force, the reversing rod 410 is driven to swing, and the valve plug 200 is driven to move to open the water outlet 101, so that the water draining function is realized.

In the washing machine of this embodiment, interior bucket can independently contain water at washing/rinsing in-process, through installing the drainage function that the interior bucket was realized to the centrifugal drainage device in interior bucket bottom, adopts the drainage of pure mechanical structure completion interior bucket, has saved the driving motor who sets up alone for the drainage of realizing interior bucket among the prior art, and the cost is reduced need not fix a position the interior bucket before the drainage simultaneously, controls simplyr. Through the structural design of the centrifugal drainage device, when the centrifugal drainage device is installed in a washing machine, the occupation of the area below the drainage port 101 can be reduced, the blockage of drainage water flow is avoided, and the drainage efficiency is improved.

In this embodiment, the first mounting portion 720 is specifically connected to the fixing portion 511 of the mounting bracket 500, and when assembling, the first mounting portion 720 and the fixing portion 511 of the mounting bracket 500 can be connected and fixed by passing a screw through the first mounting hole 721, thereby fixing the mounting bracket 500 on the flange plate 700.

In a further aspect of this embodiment, two first mounting portions 720 are symmetrically disposed in the mounting opening 710, and the extending directions of the two first mounting portions 720 are parallel to each other.

Further, both the first edges 711 are parallel to the extending direction of the first mounting portion 720.

In the centrifugal drainage device, the centrifugal slider 300 is a plate-shaped structure perpendicular to the central axis of the flange 700, and is mounted in the mounting opening 710 in a matching manner.

In the above solution, under the action of centrifugal force, the centrifugal slider 300 slides along the radial direction relative to the flange 700, and the relative positions of the mounting bracket 500 and the flange 700 are always fixed, i.e. there is relative sliding between the centrifugal slider 300 and the mounting bracket 500 in the same direction. The shape of the mounting opening 710 matches with the outline of the centrifugal slider 300, the extending directions of the first mounting portion 720 and the first edge 711 are parallel to the sliding direction of the centrifugal slider 300, and in the sliding process of the centrifugal slider 300, the gap between the edge of the mounting opening 720 and the first edge 711 and the gap between the edge of the first mounting portion 720 and the edge of the mounting bracket 500 are always kept stable, so that the unstable sliding path of the centrifugal slider 300 is avoided, and the effect of driving the valve plug 200 to move is better.

In a further aspect of this embodiment, the second edge 712 is partially recessed inward to form the drain escape opening 730, and the first mounting portion 720 is disposed on the second edge 712 in a region other than the drain escape opening 730.

Preferably, two first installation parts 720 are respectively located at both sides of the drainage escape opening 730.

When the inner barrel flange component is applied to a washing machine, the drainage avoiding opening 730 is positioned below the drainage opening 101 on the inner barrel, so that drainage water flow is avoided, the first installation part 720 is arranged in the region outside the drainage avoiding opening 730, and the phenomenon that the drainage water flow is blocked to influence the drainage efficiency of the washing machine can be prevented.

The two first mounting portions 720 are connected to the two fixing portions 511 of the mounting bracket 500, respectively, so that the mounting bracket 500 can be more stably fixed to the flange plate 700.

In this embodiment, the upper surface of the transition portion 512 connecting the two fixing portions 511 is higher than the upper surface of the fixing portion 511. A space is formed between the two first mounting portions 720, the fixing portion 511 is connected to the lower surface of the first mounting portion 720, and the transition portion 512 disposed higher than the fixing portion 511 can fill the space between the two first mounting portions 720.

Furthermore, the edge of the centrifugal slider 300 facing the central axis of the flange 700 is provided with a concave notch 311, and when the centrifugal slider 300 is located at a position close to the central axis of the flange 700, that is, the centrifugal slider 300 is not subjected to centrifugal force, so that the valve plug 200 is located at a position for blocking the drain hole 101, the mounting bracket 500 is arranged in the notch 311 in a matching manner with the first mounting portion 720 of the flange 700.

In the above embodiment, after the mounting bracket 500 is connected and fixed to the first mounting portion 720, a protruding structure with a certain size is formed inside the mounting opening 710. The centrifugal slider 300 is located entirely inside the mounting opening 710 when not subjected to centrifugal forces, and its edge facing the central axis of the flange 700 is close to the second edge 712 of the mounting opening 710. The notch 311 can avoid the protruding structure formed by the mounting bracket 500 and the first mounting part 720 at the inner side of the mounting opening 710, so that the centrifugal slider 300 can be mounted on a plane flush with the flange plate 700 without being mounted higher or lower than the flange plate 700, and the effect of reducing the height of the inner barrel flange assembly in the longitudinal direction is achieved.

In this embodiment, a central region 751 of the lower surface of the flange 700 is recessed, and the central region 751 is connected to a peripheral region 752 of the lower surface of the flange 700 by an angled transition surface 753.

The second edge 712 of the mounting opening 710 is positioned within the central region 751 and the end of the first edge 711 remote from the periphery of the flange 700 is positioned within the peripheral region 752. The first edge 711 and the second edge 712 are connected by a rounded corner 713.

The lower surface of the flange 700 outside the radius 713 is flush with a central region 751 of the lower surface of the flange 700 and defines a vertical cut 754 along an extension of the first edge 711 away from the outer periphery of the flange 700.

In this embodiment, second mounting portions 740 are formed outside the two first edges 711 of the mounting opening 710, and second mounting holes 741 are formed in the second mounting portions 740. The second mounting portion 740 is used for mounting the slide 600 for guiding the eccentric slide 300, and the second mounting portion 740 and the slide 600 can be connected by screws passing through the second mounting holes 741. The centrifugal slider 300 is slidably mounted to the slide 600 so as to be more stably slidable in the radial direction of the flange 700.

The flange plate 700 of the embodiment is provided with a mounting opening 710 formed by locally concave edges, so as to provide a space for mounting the centrifugal drainage device, and a first mounting part 720 protruding towards the inner side of the mounting opening 710 is arranged and used for being connected with the centrifugal drainage device, so that the centrifugal drainage device is fixed with the flange plate 700. The flange plate 700 and the centrifugal drainage device can be assembled in advance to form an inner barrel flange component, and then the inner barrel flange component is integrally installed in the washing machine, so that the assembling process is simple. Through the transformation to ring flange 700 structure, with the integrated setting on ring flange 700 of centrifugal drainage device, compact structure, whole small, reducible occupation to interior bucket below space is favorable to the dilatation of interior bucket.

EXAMPLE III

As shown in fig. 1 to 14, this embodiment is further limited to the first or second embodiment, and the centrifugal drainage apparatus further includes a slide way 600, and the slide way 600 is provided with a guide groove 601 parallel to the sliding direction of the centrifugal slider 300. The centrifugal slider 300 is provided with a sliding portion 321 corresponding to the guide groove 601, and the sliding portion 321 is slidably inserted into the guide groove 601.

In the above solution, the guide groove 601 on the slide 600 cooperates with the sliding portion 321 on the centrifugal slider 300 to guide the sliding direction of the centrifugal slider 300, so as to ensure that the centrifugal slider 300 can slide outward along the radial direction of the inner barrel when the centrifugal drainage device rotates with the inner barrel, thereby better driving the reversing rod 410 to push the valve plug 200 upward for drainage.

In a preferred embodiment of the present invention, the centrifugal slider 300 includes a centrifugal block body 310 and a sliding member 320 fixedly connected to the centrifugal block body 310. The sliding portion 321 is formed on the slider 320, and the slider 320 is slidably mounted on the slide 600.

Specifically, in order to provide a larger mass to generate a larger centrifugal force, the centrifugal block body 310 is made of a metal material, and if the centrifugal block body is directly mounted on the slide way 600, the friction coefficient between the two is larger, so that a larger frictional resistance is generated when the centrifugal slider 300 slides, which hinders the sliding of the centrifugal slider 300, and may cause the water outlet 101 to be unable to open.

In this embodiment, sliding members 320 are disposed on two sides of the centrifugal block body 310 for sliding in cooperation with the slide 600. The sliding member 320 is made of a material capable of reducing a friction coefficient, for example, the sliding member 320 made of plastic is fixed at two ends of the centrifugal block body 310, the friction coefficient between the sliding member 320 and the slide 600 is small, so that the sliding friction force applied to the centrifugal slider 300 can be reduced, the centrifugal slider 300 can slide under the action of a smaller centrifugal force, and the opening of the water discharge port 101 can be controlled.

In a further aspect of this embodiment, an elastic member 610 is further installed between the centrifugal slider 300 and the slide 600, that is, between the slider 320 and the slide 600, and the elastic member 610 applies a restoring force to the centrifugal slider 300, where the restoring force acts in a direction opposite to a direction in which the centrifugal slider 300 slides under the action of the centrifugal force.

Specifically, a first stopping portion 322 is disposed on the centrifugal slider 300, and a second stopping portion 602 is disposed on the slide 600 and spaced from the first stopping portion 322. Two ends of the elastic element 610 respectively abut against the opposite surfaces of the first abutting portion 322 and the second abutting portion 602.

The elastic member 610 in this embodiment is a spring, and the elastic member 610 may be any elastic device capable of providing an elastic force when being compressed.

When the centrifugal drainage device of the embodiment is installed in a washing machine, the elastic member 610 is in a compressed state in a normal state, and can apply a rightward elastic force to the centrifugal slider 300, thereby ensuring that the valve plug 200 is stably positioned at a position for closing the drainage opening 101.

When the water is drained, the inner tub rotates at a certain rotation speed, the centrifugal slider 300 slides toward the outer circumference of the tub bottom 100 against the elastic force of the elastic member 610 under the centrifugal force, and then drives the valve plug 200 to open the drain opening 101 upward through the connecting rod 420 and the reversing rod 410.

When the rotation speed of the inner tub decreases until the rotation of the inner tub stops, the centrifugal force applied to the centrifugal slider 300 is gradually reduced, and when the centrifugal force applied to the centrifugal slider 300 is smaller than the elastic force generated by the elastic member 610, the elastic member 610 pushes the first stopping portion 322 rightward, so that the centrifugal slider 300 slides toward the center of the tub bottom 100, and the valve plug 200 is pulled downward to close the drain opening 101 through the connecting rod 420 and the reversing rod 410.

In a further scheme of the embodiment, the centrifugal drainage device is mounted on the flange plate 700 to form an inner barrel flange assembly, wherein the flange plate 700 is provided with a second mounting part 740, and the centrifugal slider 300 is slidably mounted on the second mounting part 740 along the radial direction of the flange plate 700. The elastic member 610 is provided between the centrifugal slider 300 and the second mounting portion 740, and the longitudinal direction thereof is parallel to the sliding direction of the centrifugal slider 300, and the outer peripheral side of the elastic member 610 is completely covered by the centrifugal slider 300 and the second mounting portion 740.

In the above scheme, the outer circumferential side of the elastic member 610 is completely covered, so that the elastic member 610 is protected from being easily contacted with the drain water of the washing machine, and the elastic member 610 made of a metal material can avoid the situation that the elastic member 610 fails to provide a reset force due to corrosion in a humid environment for a long time. On the other hand, the elastic member 610 is prevented from being hooked with the thread scraps, so that the elastic member 610 cannot be effectively deformed to cause elastic failure. The structure protects the elastic member 610 inside the centrifugal drainage device from easily losing elasticity, thereby prolonging the service life of the centrifugal drainage device.

In another embodiment of this embodiment, a coating structure capable of coating the outer peripheral side of the elastic member may be separately formed by the centrifugal slider or the second mounting portion on the flange, thereby achieving the same effect.

In a specific aspect of this embodiment, the eccentric slider 300 has a surface opposite to and spaced apart from the second mounting portion 740, and the elastic member 610 is mounted between the surfaces of the eccentric slider 300 opposite to the second mounting portion 740.

The centrifugal slider 300 and/or the second mounting portion 740 are formed with a first covering portion 324 and a second covering portion 325, wherein the first covering portion 324 is located above the elastic member 610, and the second covering portion 325 is located below the elastic member 610. The first covering portion 324, the second covering portion 325, and the surface of the centrifugal slider 300 opposite to the second mounting portion 740 completely cover the outer circumferential side of the elastic member 610.

In detail, the first and second cover portions 324 and 325 may be formed entirely of the centrifugal slider 300, entirely of the second mounting portion 740, or one of the first and second cover portions 324 and 325 may be formed of the centrifugal slider 300 and the other may be formed of the second mounting portion 740.

In a further aspect of this embodiment, the surface of the eccentric slider 300 facing the second mounting portion 740 partially protrudes toward the second mounting portion 740 to form the first covering portion 324 and the second covering portion 325. The first covering portion 324 and the second covering portion 325 form a clamping groove 326 with an opening therebetween, the elastic member 610 is placed inside the clamping groove 326, and the opening of the clamping groove 326 is blocked by the second mounting portion 740.

The centrifugal slider 300 is provided with the first covering portion 324 and the second covering portion 325, which are matched with the second mounting portion 740 on the flange plate 700, so that the outer circumference of the elastic member 610 is completely covered by the inner surface of the clamping groove 326 and the surface of the second mounting portion 740 facing the centrifugal slider 300.

Preferably, the depth of the clamping groove 326 is gradually increased from two sides close to the first covering portion 324 and the second covering portion 325 to the middle portion, so as to form a concave curved surface connecting the first covering portion 324 and the second covering portion 325. In this embodiment, the cylindrical spring is used as the elastic member 610, and the concave curved surface formed in the clamping groove 326 can be better attached to the outer peripheral surface of the elastic member 610, so that the elastic member 610 is stably retained in the clamping groove 326 and is not easy to displace.

In a further aspect of this embodiment, the second mounting portion 740 of the flange 700 is at least partially positioned within the retaining groove 326.

The edge of the second mounting portion 740 is inserted into the clamping groove 326, so that the open blocking effect of the second mounting portion 740 on the clamping groove 326 is ensured, and the elastic member 610 is not exposed to the outside due to the dislocation of the second mounting portion 740 and the centrifugal slider 300 in the sliding process of the centrifugal slider 300. On the other hand, the clamping groove 326 extends along the direction parallel to the sliding direction of the centrifugal slider 300, the edge of the second mounting portion 740 is inserted into the clamping groove 326, and in the sliding process of the centrifugal slider 300, the clamping groove can be matched with the slide way 600 to play an auxiliary guiding role for the centrifugal slider 300, so that the stability of the sliding path of the centrifugal slider 300 is further ensured.

In this embodiment, the slide 600 is mounted on the second mounting portion 740, and two ends of the elastic element 610 respectively abut against the first abutting portion 322 on the centrifugal slider 300 and the second abutting portion 602 on the slide 600. By designing the distance between the first stop portion 322 and the second stop portion 602 and the initial length of the elastic member 610, when the valve plug 200 is located at a position for closing the drain opening 101, i.e. the centrifugal slider 300 is located near the center of the flange 700, the elastic member 610 is in a compressed state and has a certain precompression force. The elastic member 610 pushes the first stopping portion 322 rightwards by the pre-compression force, so that the centrifugal slider 300 applies a downward pulling force to the valve plug 200 through the connecting rod 420 and the reversing rod 410, and the sealing effect of the valve plug 200 on the drain opening 101 is assisted.

In a specific embodiment of this embodiment, the clamping groove 326 on the centrifugal slider 300 extends along the length direction of the elastic element 610, one end of the clamping groove 326 is closed to form the first stopping portion 322, and the other end of the clamping groove 326 is open. The second stopper 602 of the slide 600 closes the open end of the holding groove 326. The elastic element 610 is disposed inside the clamping groove 326, and two ends of the elastic element respectively abut against the first abutting portion 322 and the second abutting portion 602.

Further, the slide 600 has a slide fixing portion 603 connected to a lower surface of the second mounting portion 740, and the slide fixing portion 603 is formed with a hole. The second mounting portion 740 is provided with a second mounting hole 741, and the second mounting portion 740 and the slide fixing portion 603 can be connected into a whole by passing a screw through the second mounting hole 741 and the opening of the slide fixing portion 603, so that the slide 600 and the flange plate 700 can be mounted and fixed.

The lower edge of the surface of the slide fixing portion 603 facing the inner side of the mounting opening 710 protrudes into the mounting opening 710 to form a supporting portion 604, the second abutting portion 602 protrudes out of the surface of the slide fixing portion 603 facing the inner side of the mounting opening 710, the lower surface of the second abutting portion 602 and the upper surface of the supporting portion 604 are arranged at intervals, a guide groove 601 is formed between the two, and the guide groove is matched with the sliding portion 321 on the centrifugal slider 300 to realize the guide effect on the sliding of the centrifugal slider 300.

In the centrifugal slider 300 of the present embodiment, the sliding portion 321 and the second covering portion 325 are the same structure disposed on the centrifugal slider 300, and on one hand, cooperate with the guide groove 601 on the slide track 600 to guide the centrifugal slider 300, and on the other hand, can be used to shield the lower surface of the elastic member 610, and cooperate with the first covering portion 324 and the second mounting portion 740 to cover the outer peripheral side of the elastic member 610. The same structure realizes two effects, can simplify the structure of the centrifugal slider 300, and simultaneously makes the whole structure of the inner barrel flange component more compact.

Specifically, the centrifugal mass body 310 in the centrifugal slider 300 is only used to provide mass that can generate sufficient centrifugal force, and the mating mounting structures of the centrifugal slider 300 with the second mount 740 and the slideway 600 are formed on the slider 320. In detail, the centrifugal block body 310 extends a certain length along the circumferential direction of the flange plate 700, the sliding members 320 are disposed at two ends of the centrifugal block body 310 in the length direction, the first covering portion 324, the second covering portion 325 (i.e., the sliding portion 321) and the first abutting portion 322 are all formed by the sliding members 320, and the outer circumferential side of the elastic member 610 is completely covered by the sliding members 320 and the second mounting portion 740 on the flange plate 700.

In a further scheme of the embodiment, a limiting boss 323 is formed by partially protruding the lower surface of one end of the sliding part 321 close to the central axis of the flange 700, and the limiting boss 323 is arranged opposite to one end of the supporting part 604 close to the central axis of the flange 700.

In the above solution, the limit boss 323 cooperates with the support portion 604 to limit the slidable range of the centrifugal slider 300, and when the centrifugal slider 300 slides to the position where the limit boss 323 abuts against the right end of the support portion 604, the centrifugal slider 300 cannot slide further, so that the maximum distance that the centrifugal slider 300 can slide can be accurately controlled. Further, when the internal structure of the washing machine is designed, enough space can be reserved for the sliding of the centrifugal slider 300, and the centrifugal slider 300 is prevented from being scratched or even collided with the internal structure of the washing machine when the centrifugal slider 300 slides to open the water outlet 101.

In this embodiment, the centrifugal drainage device is integrally disposed on the flange plate 700 to form an inner barrel flange assembly, and the elastic member 610 for applying a restoring force to the centrifugal slider 300 is disposed, so that the centrifugal slider 300 can be automatically restored after the centrifugal force disappears, and the state that the valve plug 200 blocks the drain opening 101 is restored. Through the structural design of the centrifugal slider 300, the flange plate 700 and the slide 600, the elastic part 610 is completely covered by the surrounding structure and cannot be in direct contact with the drainage of the washing machine in the drainage process, so that the elastic part 610 can be prevented from being corroded or hooking thread scraps, the elastic failure of the elastic part 610 is avoided, and the service lives of the centrifugal drainage device and the washing machine are prolonged.

Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present invention.
