Example one

As shown in fig. 1 to 13, the present embodiment provides a flange 700 and an inner tub flange assembly for a washing machine.

In this embodiment, the edge of the flange plate 700 is partially recessed to form a mounting opening 710, and the mounting opening 710 has a certain extension in the circumferential direction of the flange plate 700. The mounting opening 710 has two first edges 711 at both ends in an extending direction thereof, and a second edge 712 connecting the two first edges 711. The second edge 712 is provided with a first mounting portion 720 protruding inward of the mounting opening 710.

The inner barrel flange component comprises the flange plate 700, a centrifugal drainage device is arranged in a mounting hole 710 on the flange plate 700, and the centrifugal drainage device specifically comprises:

a mounting bracket 500 connected to the first mounting portion 720;

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

the centrifugal slider 300 slides relative to the flange 700 under the action of centrifugal force, and drives the valve plug 200 to move relative to the mounting bracket 500.

In the above solution, the flange plate 700 forms the mounting opening 710 by locally recessing the edge, providing a mounting space for the centrifugal drainage device, and the centrifugal drainage device is fixed to the flange plate 700 by connecting the first mounting portion 720 protruding towards the inner side of the mounting opening 710 with the mounting bracket 500 in the centrifugal drainage device. The centrifugal drainage device is integrally integrated on the flange plate 700, the structure is compact, the occupied space is small, the centrifugal drainage device and the flange plate can be assembled in advance to form an inner barrel flange component, then the centrifugal drainage device is integrally installed in the washing machine, and the assembling process is simple.

Specifically, the first mounting portion 720 according to the present embodiment is formed to extend from the second edge 712 to the outer circumference of the flange 700 by a certain length.

In detail, the first mounting portion 720 is provided with a first mounting hole 721. Preferably, the first mounting holes 721 are provided at least two in the extending direction of the first mounting portion 720. During assembly, the first mounting portion 720 and the mounting bracket 500 are connected by a screw passing through the first mounting hole 721, so as to fix the centrifugal drainage device.

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 both 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 710 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 a drain escape opening 730, and the first mounting portion 720 is disposed on the second edge 712 in a region outside the drain escape opening 730.

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

When interior bucket flange subassembly is applied to washing machine, the drainage dodges mouthful 730 and is located the outlet 101 below on the interior bucket to dodge the drainage rivers, set up first installation department 720 in the drainage and dodge the region outside mouthful 730, prevent to cause to block the drainage rivers, influence washing machine's drainage efficiency.

In detail, the mounting bracket 500 includes a fixing portion 511 coupled to the first mounting portion 720, and a guide portion 521 for mounting the valve plug 200, which are coupled to each other by a coupling portion 522. The guide portion 521 is located in a region corresponding to the drainage escape opening 730, and the fixing portions 511 include two portions respectively located at both sides of the guide portion 521.

Because the relative fixed part 511 unsettled setting of guide part 521, all set up first installation department 720 and fixed part 511 as two, preferably relative guide part 521 symmetry to fix simultaneously in guide part 521 both sides, it is better to the fixed effect of installing support 500, the structure is more firm.

Further, the two fixing portions 511 of the mounting bracket 500 are connected by a transition portion 512, and both ends of the connecting portion 522 are respectively connected to the transition portion 512 and the guide portion 521. The guide part 521 is provided with a hollow slideway extending vertically, and one side of the transition part 512 facing the guide part 521 is provided with an arc-shaped edge, and the circle center of the arc-shaped edge is positioned on the 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.

In a further aspect of this embodiment, an upper surface of the transition portion 512 is higher than an upper surface of the fixing portion 511. The fixing portion 511 is connected to the lower surface of the first mounting portion 720 of the flange 700, and a space is provided between the two first mounting portions 720. The upper surface of the transition portion 512 is higher than the upper surface of the fixing portion 511, so that the space between the two first mounting portions 720 can be filled.

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, the mounting bracket 500 is matched with the first mounting portion 720 of the flange 700 and is arranged in the notch 311.

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 force, and its edge facing the central axis of the flange 700 is close to a second edge 712 of the mounting opening 710. The notch 311 is formed to avoid the protruding structure formed by the mounting bracket 500 and the first mounting portion 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.

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 installation opening 710 extends along the circumferential direction of the flange plate 700 to have a certain length, the centrifugal slider 300 has a flat structure and has an outline matching the installation opening 710, and the increase of the mass of the centrifugal slider 300 can be effectively realized by increasing the installation opening 710 and the extension length of the centrifugal slider 300 along the circumferential direction of the flange plate 700.

In a further aspect of 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 fillet 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 centrifugal slider 300, and specifically, the second mounting portion 740 and the slide 600 can be connected by passing a screw through the second mounting hole 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 embodiment also provides a washing machine which comprises an inner barrel and the inner barrel flange component. The inner barrel is provided with a water outlet 101, and the flange plate 700 is coaxially arranged with the barrel bottom 100 of the inner barrel and fixedly arranged on the barrel bottom 100 of the inner barrel.

In the washing/rinsing process, the valve plug 200 blocks the water outlet 101, so that the inner barrel independently holds water in the washing/rinsing process; during the draining process, the centrifugal slider 300 slides outwards along the flange 700 under the action of centrifugal force, and drives the valve plug 200 to move to open the drain opening 101 for draining.

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 in the centrifugal drainage device 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 is integrally integrated on the flange plate 700 to form an integrated inner barrel flange component which can be directly arranged on the barrel bottom 100 of the inner barrel, and the valve plug 200 corresponds to the drainage port 101 in position, so that the drainage port 101 can be controlled to be opened and closed.

During the washing/rinsing process, the inner tub is in a free state, and the valve plug 200 blocks the drain opening 101. During water drainage, the inner barrel is controlled to rotate at a certain rotating speed, so that sufficient centrifugal force is generated to enable the centrifugal slider 300 to slide, the centrifugal slider 300 slides outwards along the radial direction of the flange plate 700 under the action of the centrifugal force, the valve plug 200 is driven to move to open the water outlet 101, and the water drainage function is realized.

In the washing machine of the embodiment, the inner barrel can independently contain water in the washing/rinsing process, and the inner barrel flange component with the centrifugal drainage device is arranged below the inner barrel, so that the drainage function of the inner barrel is realized. The flange plate 700 is provided with the mounting port 710 so as to provide a mounting space for the centrifugal drainage device, the centrifugal drainage device is connected with the mounting bracket 500 in the centrifugal drainage device through the first mounting part 720, the integrated arrangement of the centrifugal drainage device on the flange plate 700 is realized, the whole structure is compact, the occupied space is small, the space occupation below the inner barrel is saved, and the expansion design of the inner barrel is facilitated.

Example two

As shown in fig. 3 to 12, the present embodiment is further defined by the first embodiment, and the centrifugal drainage device further includes a reversing transmission mechanism connecting the centrifugal slider 300 and the valve plug 200. The centrifugal slider 300 drives the valve plug 200 to move through a reversing transmission mechanism, and the reversing transmission mechanism can convert the sliding of the centrifugal slider 300 in one direction into the movement of driving the valve plug 200 in the other direction.

Specifically, as shown in fig. 3 to 9, when the centrifugal slider 300 horizontally slides along the radial direction of the flange 700, the valve plug 200 vertically moves relative to the mounting bracket 500 in a direction parallel to the central axis of the flange 700 to open/close the drain opening 101, the drain opening 101 is provided on the bottom 100 of the inner tub, and when the drain opening 101 is opened, water is directly drained downwards, and the drainage efficiency is higher.

In the centrifugal drainage apparatus of the present embodiment, the mounting bracket 500 specifically includes:

a base 510 connected to the flange 700;

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

The vertical projection of the extending direction of the connecting frame 520 on the plane of the flange plate 700 coincides with the vertical projection of the extending direction of the reversing transmission mechanism on the plane of the flange plate 700.

In the above scheme, when the flange assembly of the inner barrel is mounted on the barrel bottom 100 of the inner barrel, the connecting frame 520 and the reversing transmission mechanism of the mounting bracket 500 are located below the water outlet 101, and through the structural design of the centrifugal drainage device, the extending directions of the connecting frame 520 and the reversing transmission mechanism are superposed on the plane where the flange plate 700 is located, that is, the vertical projection on the horizontal plane in the figure, 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 water drainage efficiency.

On the other hand, the washing machine drain water 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.

The reversing transmission mechanism specifically comprises:

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.

The perpendicular projection of the extension direction of the connecting frame 520 on the plane of the flange plate 700 coincides with the perpendicular projection of the extension direction of the connecting rod 420 on the plane of the flange plate 700.

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 connecting portion 522 for connecting the base 510 and the guide portion 521.

The vertical projection of the extending direction of the connecting portion 522 on the plane of the flange 700 coincides with the vertical projection of the extending direction of the connecting rod 420 on the plane of the flange 700.

Further, the connecting rod 420 extends from the centrifugal slider 300 to the reversing rod 410 from the outside to the 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 flange plate 700 is larger than the distance between the valve plug 200 and the central axis, i.e., the centrifugal slider 300 has a larger rotation radius. In this manner, the 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, and the convex region downward on the barrel bottom 100 can be effectively avoided, so that the mounting bracket 500 can be mounted closer to the barrel bottom 100, that is, the flange plate 700 can be as close as possible to the lower surface of the barrel bottom 100 of the inner barrel, 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. The arrangement mode can enable the connecting part 522 to be closer to the connecting rod 420 in the vertical direction, the overall structural design of the centrifugal drainage device is more compact, the longitudinal height of the centrifugal drainage device is enabled to be as close as possible to the thickness of the flange plate 700, the volume of the centrifugal drainage device protruding out of the lower surface of the flange plate 700 is reduced, and therefore the occupation of the lower space of the inner barrel can be reduced when the centrifugal drainage device is applied to a washing machine, and the expansion of the inner barrel is facilitated.

In this embodiment, the base 510 specifically includes:

two fixing parts 511 which are arranged at intervals, are respectively positioned at two sides of the guide part 521 and are connected with the flange plate 700;

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.

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 the water outlet 101 is sealed from top to bottom, when water is contained in the inner barrel, 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 rod 202 in the horizontal direction, thereby effectively converting the horizontal movement of the centrifugal slider 300 into the movement of the valve plug 200 in the vertical direction by the reversing rod 410.

In this embodiment, by designing the structure of the centrifugal drainage device, the extension directions of the connection frame 520 of the mounting bracket 500 and the reversing transmission mechanism are overlapped on the plane where the flange plate 700 is located, specifically, the extension directions of the connection portion 522 and the connection rod 420 in the reversing transmission mechanism are overlapped on the plane where the flange plate 700 is located, so that the shielding of the centrifugal drainage device on the area below the water outlet 101 can be reduced, thereby reducing the blocking effect of the centrifugal drainage device on drainage water flow in the drainage process of the washing machine, and improving the drainage efficiency. Meanwhile, the connecting part 522 is vertically overlapped with the connecting rod 420, so that the area exposed in the drainage water flow is reduced, and the hooking of the thread scraps can be reduced, thereby avoiding the influence of the thread scraps hooking on the working effect of the centrifugal drainage device.

EXAMPLE III

As shown in fig. 1 to 14, the present embodiment is further defined by the first or second embodiment, and the centrifugal drainage apparatus further includes an elastic member 610 having a certain length, and the elastic member 610 applies a restoring force to the centrifugal slider 300, the restoring force being opposite to the sliding direction of the centrifugal slider 300 under the action of the centrifugal force.

The inner barrel flange component is applied to a washing machine, the inner barrel is controlled to rotate at a certain rotating speed during water drainage, the centrifugal sliding block 300 slides outwards along the radial direction of the flange plate 700 under the action of centrifugal force, and the reversing transmission mechanism drives the valve plug 200 to move to open the water outlet 101. In the process that the rotating speed of the inner barrel is reduced until the inner barrel stops rotating, the centrifugal force borne by the centrifugal slider 300 is gradually reduced, when the centrifugal force borne by the centrifugal slider 300 is smaller than the reset force generated by the elastic piece 610, the centrifugal slider 300 slides towards the center of the flange plate 700 under the action of the reset force, the valve plug 200 is driven by the reversing transmission mechanism to plug the water outlet 101, and the automatic reset of the centrifugal drainage device is realized.

In this embodiment, the longitudinal direction of the elastic member 610 is parallel to the sliding direction of the centrifugal slider 300, and the outer circumferential side of the elastic member 610 is completely covered with the centrifugal slider 300 and the second mounting portion 740 on the flange 700.

In the above scheme, the outer circumferential side of the elastic member 610 for applying the reset force to the centrifugal slider 300 is completely covered, so that the elastic member 610 is protected from being easily contacted with the drain water of the washing machine, and for the elastic member 610 made of a metal material, the elastic member 610 can be prevented from being rusted in a humid environment for a long time, so that the elastic member is prevented from being elastically failed and the reset force cannot be provided. 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.

The elastic member 610 in this embodiment is a spring, and generates an elastic force as a restoring force of the centrifugal slider 300 when being compressed. The elastic member 610 may be any elastic means that can provide an elastic force when it is compressed.

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, and the first covering portion and the second covering portion are matched with the second mounting portion 740 on the flange 700, so that the outer peripheral side of the elastic element 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, and the structure is simple and easy to realize.

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 disposed within the clamping slot 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 a further aspect of this embodiment, the centrifugal slider 300 is provided with a first stopping portion 322, and the slide 600 has a second stopping portion 602 opposite to and spaced apart 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.

By designing the spacing distance between the first stop portion 322 and the second stop portion 602, and the initial length of the elastic member 610, the elastic member 610 has a certain precompression force when the valve plug 200 is located at a position for closing the drain opening 101, that is, the centrifugal slider 300 is located near the central axis of the flange 700. 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.

When the eccentric sliding block 300 slides towards the periphery of the flange 700, the first stopping portion 322 and the second stopping portion 602 gradually approach each other, and further compress the elastic member 610 to generate a larger elastic force, and drive the valve plug 200 to open the drain opening 101. When the centrifugal force applied to the centrifugal slider 300 gradually disappears, the elastic force generated by the elastic member 610 can be used as a restoring force of the centrifugal slider 300, and the centrifugal slider 300 slides toward the central axis of the flange 700 by pushing the first stopping portion 322 rightward, so as to drive the valve plug 200 to re-close the water outlet 101.

Specifically, the clamping groove 326 extends along the length direction of the elastic member 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.

In a further aspect of this embodiment, the slide 600 is provided with a guide groove 601, the centrifugal slider 300 is provided with a sliding portion 321 extending along the sliding direction of the centrifugal slider 300, and the sliding portion 321 is slidably inserted into the guide groove 601.

In the above scheme, the guide groove 601 on the slide 600 is matched with the sliding portion 321 on the centrifugal slider 300, so as to play a main guiding role in the sliding process of the centrifugal slider 300, and the second mounting portion 740 is matched with the auxiliary guiding role of the centrifugal slider 300, so that the centrifugal slider 300 can be prevented from deviating from the sliding path, and the valve plug 200 can be driven to move more stably.

Specifically, 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 an opening. 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 is spaced from the upper surface of the supporting portion 604, and a guide groove 601 is formed between the lower surface of the second abutting portion 602 and the upper surface of the supporting portion 604.

In this 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 600 to guide the centrifugal slider 300, and on the other hand, can be used to block 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.

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. Furthermore, 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 phenomenon that the centrifugal slider 300 is scratched or even collided with the internal structure of the washing machine when the water outlet 101 is opened by the sliding of the centrifugal slider 300 is avoided.

In a further aspect of the present embodiment, the centrifugal slider 300 includes a centrifugal mass body 310, and a sliding member 320 fixedly connected to the centrifugal mass body 310. The centrifugal slider 300, the second mounting portion 740 and the slide 600 are formed on the sliding member 320, and the centrifugal slider 300 is slidably mounted on the flange 700 and the slide 600 via the sliding member 320.

Specifically, 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 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, and the sliding of the centrifugal slider 300 is hindered, which may cause a situation that the water outlet 101 cannot be opened.

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 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.
