In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "connected" are to be construed broadly, e.g., as being fixed or detachable or integrally connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in a specific case to those of ordinary skill in the art.

Example one

As shown in fig. 1 to 8, the flange assembly of the inner tub of the washing machine according to the present embodiment includes a flange body 100, a sealing plug 200 disposed on the flange body 100, and a driving part including a centrifugal slider 300. The centrifugal slider 300 has a driving surface 321, and the centrifugal slider 300 slides along the radial direction of the flange body 100, and the sealing plug body 200 is in contact with and matched with the driving surface 321 to move.

In the above scheme, the sealing plug body 200 and the centrifugal slider 300 are integrally arranged on the flange body 100, so that the structure is compact, the occupied space is small, the condition that the centrifugal drainage structure occupies a larger space below the inner barrel in the prior art is avoided, and the capacity expansion of the inner barrel is facilitated. The inner barrel flange component can be directly installed below an inner barrel of a washing machine as an integral structure, and the flange body 100 is fixedly connected with the barrel bottom 1 of the inner barrel, and the sealing plug body 200 is correspondingly installed at the drainage port 2, so that the application of the inner barrel flange in the washing machine is realized.

In a further aspect of the present embodiment, the centrifugal slider 300 includes a supporting portion 320 and a centrifugal portion 310, and the driving surface 321 is an inclined supporting surface disposed on the supporting portion 320 and gradually decreasing in height from inside to outside along the radial direction of the flange body 100.

The centrifugal slider 300 slides from inside to outside along the radial direction of the flange body 100, and the driving surface 321 pushes the sealing plug body 200 to move upwards.

In the above scheme, by providing the inclined supporting surface as the driving surface 321 to contact and cooperate with the seal plug body 200, when the centrifugal slider 300 slides along the radial direction of the flange body 100, the seal plug body 200 can move in the vertical direction along with the driving surface 321, and the structure is simple and easy to implement. As shown in fig. 5 to 8, when the centrifugal slider 300 slides outward by centrifugal force, the driving surface 321 pushes the sealing stopper body 200 upward to open the drain opening 2. When the centrifugal slider 300 slides inward and resets, the sealing plug body 200 falls back along the driving surface 321 under the action of gravity, and the water outlet 2 is sealed from the inside of the inner barrel from top to bottom.

In another aspect of this embodiment, the driving surface 321 may also be an inclined supporting surface that is disposed on the supporting portion 320 and gradually increases in height from inside to outside along the radial direction of the flange body 100.

The centrifugal slider 300 slides from inside to outside along the radial direction of the flange body 100, and the sealing plug body 200 moves downwards along the driving surface 321.

In the above scheme, the sealing plug body 200 is arranged below the inner barrel, and the water outlet 2 is sealed from the outside of the inner barrel from bottom to top. When the centrifugal slider 300 slides outward by centrifugal force, the sealing stopper body 200 descends along the driving surface 321 by gravity to open the drain opening 2. When the centrifugal slider 300 slides inward and resets, the driving surface 321 pushes the sealing plug body 200 upward to seal the water outlet 2 from the outside of the inner barrel.

In a preferred embodiment of the present invention, the sealing plug 200 has a mating surface 204 inclined in the same direction as the driving surface 321, and the mating surface 204 and the driving surface 321 are slidably attached to each other.

In the above-described aspect, the mating surface 204 that is in sliding contact with the driving surface 321 is provided, so that the contact between the seal plug body 200 and the support portion 320 of the centrifugal slider 300 is surface contact, and the support of the seal plug body 200 by the support portion 320 is further stabilized.

In a further aspect of the present embodiment, the supporting portion 320 is disposed below the seal plug body 200, the centrifugal portion 310 is disposed outside the seal plug body 200 along the radial direction of the flange body 100, and the centrifugal slider 300 further includes a transition portion 330 connecting the supporting portion 320 and the centrifugal portion 310.

In the above-mentioned solution, the mass of the centrifugal slider 300 is mainly concentrated on the centrifugal portion 310, and the centrifugal portion 310 provides the centrifugal force for sliding the centrifugal slider 300. In the radial direction of the flange body 100, the centrifugal part 310 is closer to the periphery of the flange body 100 relative to the seal plug body 200, the distance between the centrifugal part 310 and the central axis of the flange body 100 is increased, and under the condition that the mass of the centrifugal part 310 is certain, because the rotating radius of the centrifugal part is larger, a larger centrifugal force can be provided at the same rotating speed, and the condition that the centrifugal slider 300 cannot drive the seal plug body 200 to move is avoided.

Further, the centrifugal part 310 is a plate-shaped structure perpendicular to the central axis of the flange body 100, and the transition part 330 extends from the centrifugal part 310 along the radial direction of the flange body 100 and is connected to the support part 320. The support portion 320 extends upward from the end of the transition portion 330 to form a drive surface 321 for contacting and mating with the plug body 200.

For the pulsator washing machine, due to the limitation of the highest rotation speed that can be achieved, in order to provide enough centrifugal force to open the water outlet 2 through the centrifugal slider 300, the mass of the centrifugal part 310 needs to be increased, that is, the volume of the centrifugal part 310 needs to be increased. In the above solution, the centrifugal part 310 is designed to be a plate-shaped structure, so that the centrifugal part can be attached to the flange body 100, or an installation opening matched with the shape of the centrifugal part 310 is formed from the outer periphery of the flange body 100 to the inner side for installation, and the flange does not occupy an extra space below the flange body 100, and has a compact overall structure and a small occupied space.

The supporting portion 320 is disposed at one end of the transition portion 330 near the central axis of the flange body 100, extends vertically upward, and the top end forms an inclined driving surface 321, which can better cooperate with the sealing plug body 200 disposed above.

Preferably, the upper surface of the transition portion 330 is a concave curved surface with gradually increasing height from inside to outside along the radial direction of the flange body 100. The concave curved surface is used for avoiding the structure of the sealing plug body 200 and the barrel bottom 1 of the inner barrel at the water outlet 2, and preventing the centrifugal slider 300 from interfering with the barrel bottom 1 of the inner barrel.

In this embodiment, a structure is adopted in which the sealing plug body 200 blocks the water outlet 2 from the top to the bottom inside the inner barrel.

Specifically, the sealing plug body 200 comprises a sealing cover 201 and a supporting rod 202, wherein one end of the supporting rod 202 is fixedly connected with the sealing cover 201, and the other end of the supporting rod 202 is in contact fit with the driving surface 321.

The end of the support rod 202 contacting and engaging the driving surface 321 has an engaging surface 204 slidably engaging the driving surface 321.

Further, a mounting seat 500 is fixedly arranged on the flange body 100, and the mounting seat 500 includes a fixing portion 501 and a guide portion 502 having a hollow slide way, which is arranged to extend in a direction parallel to the central axis of the flange body 100.

The fixing portion 501 is fixedly connected to the flange body 100, and the guiding portion 502 is slidably sleeved on the supporting rod 202. The support part 320 of the centrifugal slider 300 extends into the hollow slide from the lower end of the guide part 502, and the driving surface 321 is provided at the upper end of the support part 320 and is in contact fit with the lower end of the support rod 202.

Preferably, the sealing gasket 203 is fixedly arranged on the lower side of the periphery of the sealing cover 201, and when the sealing plug body 200 is used for sealing the drainage opening 2, the sealing gasket 203 is in sealing fit with the periphery of the drainage opening 2, so that a better sealing effect is achieved.

When the flange component of the inner barrel is installed, the sealing cover 201 is arranged inside the inner barrel, and the support rod 202 penetrates out of the water outlet 2 to be in contact fit with the supporting part 320 below. The sealing plug body 200 blocks the water outlet 2 from the inside of the inner tub, and when water is contained in the inner tub, water pressure acts on the upper surface of the sealing cover 201 to provide auxiliary sealing force, and the sealing effect is better. The provision of the guide portion 502 restricts the movement of the sealing plug body 200 in the horizontal direction, ensuring that the sealing plug body 200 moves vertically along the driving surface 321 to open/close the drain opening 2.

As shown in fig. 5 to 8, in the present embodiment, after the flange body 100 is mounted on the bottom 1 of the inner tub of the washing machine, the sealing plug 200 seals the water outlet 2 from the inside of the inner tub from top to bottom. During water drainage, the centrifugal slider 300 slides outward along the radial direction of the flange body 100 under the action of centrifugal force, the driving surface 321 pushes the lower end of the support rod 202 upward, the sealing plug body 200 is pushed out from the water outlet 2, and the water outlet 2 is opened.

On the other hand, the sealing plug body 200 blocks the water outlet 2 through the sealing cover 201, the driving surface 321 pushes the sealing plug body 200 upwards to open the water outlet 2, the space between the bottom 1 of the inner barrel and the impeller is effectively utilized, the opening height of the opened water outlet 2 can reach 12mm, and washing foreign matters such as buttons, hair clips, coins, thread scraps and the like can be effectively discharged.

In a further scheme of this embodiment, one side of the centrifugal part 310 close to the central axis of the flange body 100 is provided with a concave bypass opening 301, and the bypass opening 301 has an arc-shaped edge, and the radius of the arc-shaped edge is greater than that of the water discharge opening 2.

The eccentric portion 310 has a first position close to the central axis of the flange body 100 as shown in fig. 5 and 6, and a second position relatively far from the central axis of the flange body 100 as shown in fig. 7 and 8. When the eccentric part 310 is at the first position, the sealing plug body 200 blocks the water outlet 2, and when the eccentric part 310 slides to the second position, the sealing plug body 200 is pushed upwards to open the water outlet 2. When the centrifugal slider 300 is at the first position, the center of the arc-shaped edge of the avoidance port 301 is located below the support rod 202.

In this embodiment, the arrangement of the avoiding opening 301 ensures that the centrifugal slider 300 does not block the space below the water outlet 2 when the water outlet 2 is opened, so that the water discharging process is smoother. On the other hand, in order to realize better matching with the sealing plug body 200, the barrel bottom 1 is convexly arranged below the inner barrel at the periphery of the water outlet 2, and the avoidance port 301 is arranged to avoid the bulge of the barrel bottom 1 at the water outlet 2 when the centrifugal part 310 is at the first position.

In this embodiment, the specific mounting structure of the centrifugal slider 300 and the flange body 100 is as follows.

The flange body 100 is fixedly installed with a guide rail 600, and the eccentric portion 310 of the eccentric slider 300 is slidably disposed on the guide rail 600.

Preferably, the flange body 100 has an inwardly concave mounting opening at an edge thereof, two guide rails 600 are arranged in parallel and fixedly mounted at both sides of the mounting opening, respectively, and the eccentric portion 310 is disposed between the two guide rails 600.

Specifically, as shown in fig. 4, a guide groove 603 is formed in the guide rail 600, mounting portions 302 are respectively provided on both sides of the centrifugal portion 310, and the mounting portions 302 are slidably provided in the guide groove 603. The eccentric portion 310 is further provided with a first limiting portion 303, the guide rail 600 is provided with a second limiting portion 604, and the first limiting portion 303 and the second limiting portion 604 have opposite surfaces to prevent the eccentric portion 310 from being separated from the guide rail 600 when the eccentric slider 300 slides to the outside of the flange body 100.

Further, an elastic member for providing a restoring force to the centrifugal slider 300 in a direction opposite to the centrifugal force is further installed on the guide rail 600.

Preferably, the guide rail 600 includes a guide bar 601 extended in a sliding direction of the centrifugal slider 300, and the centrifugal part 310 is provided with a positioning hole into which the guide bar 601 is inserted. The elastic member is a spring 602 sleeved on the guide rod 601, and two ends of the spring 602 respectively abut against the surfaces of the centrifugal part 310 and the guide rail 600.

Specifically, one end of the guide rod 601 is fixed on the surface of the second position-limiting portion 604 facing the first position-limiting portion 303, and the other end is suspended. A positioning hole is provided through the first stopper 303 of the centrifugal slider 300, and the free end of the guide rod 601 is inserted into the positioning hole. The spring 602 is sleeved on the guide rod 601, and two ends of the spring respectively abut against the first limiting portion 303 and the second limiting portion 604.

When discharging water, the inner tub rotates at a constant speed, the centrifugal slider 300 slides outward of the flange body 100 against the elastic force of the spring 602 by centrifugal force, and pushes the sealing plug 200 to open the drain port 2 through the driving surface 321. When the rotation speed of the inner barrel is reduced until the inner barrel stops rotating, the centrifugal force is gradually reduced, and when the centrifugal force applied to the centrifugal slider 300 is smaller than the elastic force of the spring 602, the spring 602 pushes the first limiting part 303 towards the inner side of the flange body 100, so that the centrifugal slider 300 slides towards the inner side of the flange body 100, and the sealing plug body 200 falls along the driving surface 321 to block the water outlet 2.

In this embodiment, the sealing plug body 200 and the centrifugal slider 300 are integrally disposed on the flange body 100, and when the sealing plug body and the centrifugal slider are applied to a washing machine, they can be directly mounted below the inner tub as an integral structure, and have a compact structure and a small occupied space. The centrifugal slider 300 is designed to be matched with the flange body 100, so that the space below the inner tub is not additionally occupied under the condition of increasing the mass of the centrifugal part 310, the overall structure is more compact, and meanwhile, the centrifugal slider can adapt to the maximum rotating speed which can be reached by the pulsator washing machine and provide enough centrifugal force to open the water outlet 2.

Example two

As shown in fig. 3, the washing machine of the present embodiment includes an inner tub and the inner tub flange assembly of the first embodiment. The flange body 100 is coaxially arranged with the barrel bottom 1 of the inner barrel and is fixedly arranged on the barrel bottom 1 of the inner barrel. The bottom 1 of the inner barrel is provided with a water outlet 2.

In the washing/rinsing process, the sealing plug body 200 blocks the water outlet 2, so that the inner barrel can independently contain water in the washing/rinsing process.

During the draining process, the centrifugal slider 300 slides along the radial direction of the flange body 100 under the action of centrifugal force, and the sealing plug body 200 moves along with the contact and engagement of the driving surface 321 to open the draining port 2.

In this embodiment, the wall of the inner tub is not provided with dewatering holes, and the water outlet 2 is blocked by the sealing plug body 200 to form a closed inner tub during the washing/rinsing process, so that the inner tub can independently contain water during the washing/rinsing process. The washing machine does not need to be provided with an outer barrel, so that the expansion of the inner barrel is realized. When the outer barrel is arranged outside the inner barrel, because the inner barrel independently holds water in the washing/rinsing process, no water is stored between the inner barrel and the outer barrel, on one hand, the using amount of washing/rinsing water is saved, on the other hand, the residue of dirt and thread scraps between the inner barrel and the outer barrel is avoided, and the washing/rinsing machine is more sanitary.

The drainage of the inner tub is achieved by a drain valve assembly integrated on the flange body 100. Specifically, in the washing/rinsing process, the inner tub is in a free state, and the sealing stopper 200 blocks the drain port 2. 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 slide block 300 to slide, the centrifugal slide block 300 slides outwards along the radial direction of the flange body 100 under the action of the centrifugal force, and the sealing plug body 200 moves along with the driving surface 321 to open the water outlet 2, so that the water drainage function is realized.

In this embodiment, the inner barrel can independently contain water in the washing/rinsing process, the water drainage function of the inner barrel is realized through the sealing plug body 200 and the centrifugal slider 300 which are integrated on the flange body 100, the water drainage of the inner barrel is completed by adopting a pure mechanical structure, the driving motor which is arranged independently for realizing the water drainage of the inner barrel in the prior art is omitted, the cost is reduced, meanwhile, the inner barrel does not need to be positioned before the water drainage, and the control is simpler. The sealing plug body 200 and the centrifugal slider 300 are integrated on the flange body 100, so that the structure is compact, the occupied space is small, and the expansion of the inner barrel of the washing machine is facilitated.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
