Description

Technical Field

[0001] The invention belongs to the technical field of washing machines, and in particular relates to an inner barrel flange assembly of a washing machine and the washing machine. Background Art

[0002] Most existing washing machines include an inner barrel and an outer barrel that are interconnected. When the washing machine is working, the outer barrel contains washing water, and the inner barrel contains clothes to be washed. The washing water can exist between the inner barrel and the outer barrel. As the working time of the washing machine increases, the dirt and lint in the washing water will be retained in the space between the inner barrel and the outer barrel, and it is difficult to clean, resulting in bacteria and odor after years of use. To solve this problem, the prior art proposes a washing machine without a dehydration hole on the inner barrel, so that the inner barrel can independently hold washing water during the washing process, but at the same time, the existing drainage method cannot achieve drainage of the hole-free inner barrel.

[0003] Chinese patent application number 201610767640.4 discloses a washing machine with no water between inner and outer barrels, comprising: an outer barrel; an inner barrel rotatably arranged in the outer barrel; during the washing / rinsing process, the inner barrel is filled with water, and there is no water between the inner barrel and the outer barrel; a drainage hole is provided at the bottom of the inner barrel, and a drainage sealing device is provided on the outer wall of the bottom of the inner barrel corresponding to the drainage hole; during washing / rinsing, the drainage sealing device keeps the drainage hole closed, and during dehydration, the drainage sealing device opens the drainage hole under the action of centrifugal force.

[0004] However, in the above scheme, adding a drainage sealing device under the inner barrel occupies the space at the bottom of the inner barrel, which is not conducive to the expansion of the inner barrel. When the volume of the centrifugal block is limited, it is further limited by the rotation speed of the pulsator washing machine. The centrifugal force that the centrifugal block can provide is limited, and the drainage sealing device may not be able to open the drainage hole. At the same time, since the valve plug and the centrifugal block move synchronously along the radial direction of the inner barrel, an inlet pipe, a connecting pipe, a sealing pipe and an outlet pipe are also arranged under the inner barrel to cooperate with the movement direction of the valve plug to achieve the sealing of the inner barrel. The structure is complex, and the sealing effect is not ideal due to the influence of water pressure.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an inner barrel flange assembly of a washing machine and a washing machine, in which a sealing plug body and a centrifugal slider are integrated on a flange body, the structure is compact, and the space occupied is small.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] An inner drum flange assembly of a washing machine comprises a flange body, a sealing plug body arranged on the flange body, and a driving component, wherein the driving component comprises a centrifugal slider; the centrifugal slider has a driving surface, the centrifugal slider slides along the radial direction of the flange body, and the sealing plug body contacts and cooperates with the driving surface and moves accordingly.

[0009] Furthermore, the centrifugal slider includes a supporting portion and a centrifugal portion, and the driving surface is an inclined supporting surface arranged on the supporting portion and gradually decreasing in height from inside to outside along the radial direction of the flange body;

[0010] The centrifugal slider slides radially from inside to outside along the flange body, and the driving surface pushes the sealing plug body to move upward.

[0011] Furthermore, the centrifugal slider includes a supporting portion and a centrifugal portion, and the driving surface is an inclined supporting surface arranged on the supporting portion and gradually increasing in height from inside to outside along the radial direction of the flange body;

[0012] The centrifugal sliding block slides radially from inside to outside along the flange body, and the sealing plug moves downward along the driving surface.

[0013] Furthermore, the sealing plug body has a mating surface inclined in the same direction as the driving surface, and the mating surface and the driving surface are arranged to be relatively slidable in contact with each other.

[0014] Furthermore, the support portion is arranged below the sealing plug body, the centrifugal portion is arranged on the radial outer side of the sealing plug body along the flange body, and the centrifugal slider also includes a transition portion connecting the support portion and the centrifugal portion.

[0015] Furthermore, the centrifugal part is a plate-like structure perpendicular to the central axis of the flange body, the transition part extends radially from the centrifugal part along the flange body and connects to the support part, and the support part extends upward from the end of the transition part to form a driving surface that contacts and cooperates with the sealing plug body.

[0016] Furthermore, the upper surface of the transition portion is an inner concave curved surface whose height gradually increases from inside to outside along the radial direction of the flange body.

[0017] Furthermore, the sealing plug body comprises a sealing cover and a support rod, one end of the support rod is fixedly connected to the sealing cover, and the other end of the support rod is in contact with the driving surface;

[0018] Preferably, one end of the support rod that contacts and cooperates with the driving surface has a mating surface that is arranged to fit and slide relative to the driving surface.

[0019] Furthermore, a mounting seat is fixedly arranged on the flange body, and the mounting seat comprises a fixing portion and a guide portion having a hollow slideway, and the hollow slideway is extended in a direction parallel to the central axis of the flange body;

[0020] The fixing part is fixedly connected to the flange body, and the guiding part is relatively slidably sleeved on the supporting rod; the centrifugal sliding block includes a supporting part extending into the hollow slideway, and the driving surface is arranged on the supporting part and contacts and cooperates with one end of the supporting rod.

[0021] Another object of the present invention is to provide a washing machine, comprising an inner tub and the inner tub flange assembly described above, wherein the flange body is coaxially arranged with the bottom of the inner tub and fixedly mounted on the bottom of the inner tub; a drainage port is provided on the bottom of the inner tub;

[0022] During the washing / rinsing process, the sealing plug body blocks the drain port, so that the inner barrel can independently hold water during the washing / rinsing process;

[0023] During the drainage process, the centrifugal slider slides radially along the flange body under the action of centrifugal force, and the sealing plug body contacts and cooperates with the driving surface and moves accordingly to open the drainage port.

[0024] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0025] The inner barrel flange assembly of the present invention integrates the sealing plug body and the centrifugal slider on the flange body, has a compact structure, occupies a small space, and the sealing plug body can move with the driving surface of the centrifugal slider. The drainage function of the independent water-containing inner barrel can be achieved through a simple mechanical structure, reducing the manufacturing cost.

[0026] The inner barrel flange assembly of the present invention provides an inclined support surface as a driving surface to contact and cooperate with the sealing plug body, so that when the centrifugal slider slides along the radial direction of the flange body, the sealing plug body can move in the vertical direction with the driving surface. The structure is simple and easy to implement. The sealing plug body is provided with a matching surface that fits and slides with the driving surface, which provides more stable support for the sealing plug body.

[0027] The inner barrel flange assembly of the present invention has a structural design for the centrifugal slider, so that the centrifugal part of the plate-like structure can be installed on the flange body, or an installation opening matching the shape of the centrifugal part is opened on the flange body for installation, thereby increasing the mass of the centrifugal part to provide a greater centrifugal force without occupying additional space under the inner barrel, and the overall structure is more compact.

[0028] In the washing machine of the present invention, the sealing plug body blocks the drain port during the washing / rinsing process to form a closed inner barrel, thereby avoiding the situation where water accumulates between the inner and outer barrels and causes dirt and lint to remain. The sealing plug body can open the drain port for drainage under the drive of the centrifugal slider, and the drainage function of the inner barrel is realized through a purely mechanical structure, thereby reducing the manufacturing cost. At the same time, when draining water, it is only necessary to control the inner barrel to rotate at a certain speed, and it is not necessary to position the inner barrel, and the control method is simpler.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] Embodiment 1

[0045] like Figures 1 to 8 As shown, the inner drum flange assembly of the washing machine described in this embodiment includes a flange body 100, a sealing plug body 200 arranged on the flange body 100, and a driving component, wherein the driving component includes 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 contacts and cooperates with the driving surface 321 and moves accordingly.

[0046] In the above scheme, the sealing plug body 200 and the centrifugal slider 300 are integrated on the flange body 100, which has a compact structure and occupies a small space, avoiding the situation in the prior art that the centrifugal drainage structure occupies a large space under the inner barrel, which is conducive to the expansion of the inner barrel. The inner barrel flange assembly as an integral structure can be directly installed under the inner barrel of the washing machine. By fixing the flange body 100 with the barrel bottom 1 of the inner barrel and installing the sealing plug body 200 at the drain port 2, the inner barrel flange of this embodiment can be used in the washing machine.

[0047] In a further solution of this embodiment, the centrifugal slider 300 includes a support portion 320 and a centrifugal portion 310 , and the driving surface 321 is an inclined support surface arranged on the support portion 320 and gradually decreasing in height from inside to outside along the radial direction of the flange body 100 .

[0048] The centrifugal slider 300 slides radially from inside to outside along the flange body 100, and the driving surface 321 pushes the sealing plug body 200 to move upward.

[0049] In the above solution, by setting the inclined support surface as the driving surface 321 to contact and cooperate with the sealing plug body 200, when the centrifugal slider 300 slides along the radial direction of the flange body 100, the sealing plug body 200 can move in the vertical direction with the driving surface 321, which has a simple structure and is easy to implement. Figures 5 to 8 As shown, when the centrifugal slider 300 slides outward under the action of centrifugal force, the driving surface 321 pushes the sealing plug body 200 upward to open the drain port 2. When the centrifugal slider 300 slides inward to reset, the sealing plug body 200 falls back along the driving surface 321 under the action of gravity, and blocks the drain port 2 from top to bottom from the inside of the inner barrel.

[0050] In another solution of this embodiment, the driving surface 321 may also be an inclined supporting surface provided on the supporting portion 320 and whose height gradually increases from the inside to the outside along the radial direction of the flange body 100 .

[0051] The centrifugal slider 300 slides radially from inside to outside along the flange body 100 , and the sealing plug body 200 moves downward along the driving surface 321 .

[0052] In the above scheme, the sealing plug body 200 is arranged below the inner barrel, and blocks the drain port 2 from the outside of the inner barrel from bottom to top. When the centrifugal slider 300 slides outward under the action of centrifugal force, the sealing plug body 200 descends along the driving surface 321 under the action of gravity to open the drain port 2. When the centrifugal slider 300 slides inward to reset, the driving surface 321 pushes the sealing plug body 200 upward to block the drain port 2 from the outside of the inner barrel.

[0053] In a preferred solution of this embodiment, the sealing plug body 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 arranged to be relatively slidable in a fitting manner.

[0054] In the above scheme, by setting a mating surface 204 that slides with the driving surface 321, the contact between the sealing plug body 200 and the supporting portion 320 of the centrifugal slider 300 is made into surface contact, and the support portion 320 supports the sealing plug body 200 more stably.

[0055] In a further solution of this embodiment, the support portion 320 is arranged below the sealing plug body 200, the centrifugal portion 310 is arranged on the radial outer side of the sealing plug body 200 along the flange body 100, and the centrifugal slider 300 also includes a transition portion 330 connecting the support portion 320 and the centrifugal portion 310.

[0056] In the above scheme, the mass of the centrifugal slider 300 is mainly concentrated on the centrifugal part 310, and the centrifugal part 310 provides the centrifugal force that drives the centrifugal slider 300 to slide. In the radial direction of the flange body 100, the centrifugal part 310 is closer to the outer periphery of the flange body 100 relative to the sealing plug body 200, which increases the distance between the centrifugal part 310 and the central axis of the flange body 100. When the mass of the centrifugal part 310 is constant, due to its larger rotation radius, it can provide a greater centrifugal force at the same speed, thereby avoiding the situation where the centrifugal slider 300 cannot drive the sealing plug body 200 to move.

[0057] Further, the centrifugal part 310 is a plate-like structure perpendicular to the central axis of the flange body 100, and the transition part 330 extends radially from the centrifugal part 310 along the flange body 100 to connect to the support part 320. The support part 320 extends upward from the end of the transition part 330 to form a driving surface 321 that contacts and cooperates with the sealing plug body 200.

[0058] For a pulsator washing machine, due to the limitation of the maximum speed it can reach, in order to provide sufficient centrifugal force to open the drain port 2 through the centrifugal slider 300, it is necessary to increase the mass of the centrifugal part 310, that is, it is necessary to increase the volume of the centrifugal part 310. In the above scheme, the centrifugal part 310 is designed as a plate-like structure, so that it can be installed on the flange body 100, or an installation opening matching the shape of the centrifugal part 310 is opened from the outer circumference of the flange body 100 to the inside for installation, without occupying additional space under the flange body 100, and the overall structure is compact and occupies little space.

[0059] The support portion 320 is arranged at one end of the transition portion 330 close to the central axis of the flange body 100, extending vertically upward, and forming an inclined driving surface 321 at the top, which can better cooperate with the sealing plug body 200 arranged above.

[0060] Preferably, the upper surface of the transition portion 330 is a concave curved surface whose height gradually increases from inside to outside along the radial direction of the flange body 100. The concave curved surface is used to avoid the sealing plug body 200 and the bottom 1 structure of the inner barrel at the drain port 2, and prevent the centrifugal slider 300 from interfering with the bottom 1 of the inner barrel.

[0061] In this embodiment, a sealing plug body 200 is used to seal the drain outlet 2 from top to bottom inside the inner barrel.

[0062] Specifically, the sealing plug body 200 includes a sealing cover 201 and a support rod 202 , one end of the support rod 202 is fixedly connected to the sealing cover 201 , and the other end is in contact with the driving surface 321 .

[0063] One end of the support rod 202 that contacts and cooperates with the driving surface 321 has a matching surface 204 that is arranged to be slidable relative to the driving surface 321 .

[0064] Furthermore, a mounting seat 500 is fixedly disposed on the flange body 100 , and the mounting seat 500 includes a fixing portion 501 and a guide portion 502 having a hollow slideway, and the hollow slideway is extended in a direction parallel to the central axis of the flange body 100 .

[0065] The fixing portion 501 is fixedly connected to the flange body 100, and the guide portion 502 is relatively slidably sleeved on the support rod 202. The support portion 320 of the centrifugal slider 300 extends from the lower end of the guide portion 502 into the hollow slideway, and the driving surface 321 is arranged at the upper end of the support portion 320 and contacts and cooperates with the lower end of the support rod 202.

[0066] Preferably, a sealing gasket 203 is fixedly provided on the lower side of the outer periphery of the sealing cover 201, and when the sealing plug body 200 blocks the drain outlet 2, the sealing gasket 203 is sealed and fitted with the outer periphery of the drain outlet 2, thereby achieving a better sealing effect.

[0067] When the inner barrel flange assembly of this embodiment is installed, the sealing cover 201 is set inside the inner barrel, and the support rod 202 passes through the drain port 2 and contacts and cooperates with the support portion 320 below. The sealing plug body 200 blocks the drain port 2 from the inside of the inner barrel. When the inner barrel is filled with water, 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 setting of the guide portion 502 limits 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 / block the drain port 2.

[0068] like Figures 5 to 8 As shown, in this embodiment, after the flange body 100 is installed with the inner barrel bottom 1 of the washing machine, the sealing plug body 200 blocks the drain port 2 from top to bottom from the inside of the inner barrel. When draining water, the centrifugal slider 300 slides radially outward along the flange body 100 under the action of centrifugal force, and the driving surface 321 pushes the lower end of the support rod 202 upward, pushing the sealing plug body 200 away from the drain port 2, and opening the drain port 2.

[0069] On the other hand, the sealing plug body 200 blocks the drain outlet 2 through the sealing cover 201, and the driving surface 321 pushes the sealing plug body 200 upward to open the drain outlet 2, effectively utilizing the space between the bottom 1 of the inner barrel and the impeller, so that the opening height of the drain outlet 2 after being opened can reach 12 mm, which can effectively discharge washing foreign objects such as buttons, hairpins, coins, and thread scraps.

[0070] In a further solution of this embodiment, the centrifugal portion 310 has a concave avoidance opening 301 on one side close to the central axis of the flange body 100 . The avoidance opening 301 has an arc-shaped edge, and the radius of the arc-shaped edge is greater than the radius of the drain port 2 .

[0071] The centrifugal part 310 has Figure 5 and Figure 6 The first position close to the central axis of the flange body 100 as shown, and Figure 7 and Figure 8 The second position shown is relatively far from the central axis of the flange body 100. When the centrifugal part 310 is in the first position, the sealing plug body 200 blocks the drain port 2, and when the centrifugal part 310 slides to the second position, the sealing plug body 200 is pushed upward to open the drain port 2. When the centrifugal slider 300 is in the first position, the center of the arc edge of the avoidance port 301 is located below the support rod 202.

[0072] In this embodiment, the setting of the avoidance opening 301 ensures that when the drain port 2 is opened, the centrifugal slider 300 does not block the space below the drain port 2, and the drainage process is smoother. On the other hand, in order to achieve better cooperation with the sealing plug body 200, the barrel bottom 1 is convexly arranged at the outer periphery of the drain port 2 toward the lower part of the inner barrel, and the avoidance opening 301 is provided to achieve the avoidance of the protrusion of the barrel bottom 1 at the drain port 2 when the centrifugal part 310 is in the first position.

[0073] In this embodiment, the specific installation structure of the centrifugal slider 300 and the flange body 100 is as follows.

[0074] The guide rail 600 is fixedly mounted on the flange body 100 , and the centrifugal portion 310 of the centrifugal slider 300 is slidably disposed on the guide rail 600 .

[0075] Preferably, the edge of the flange body 100 has a concave mounting opening, two guide rails 600 are arranged in parallel and fixedly installed on both sides of the mounting opening respectively, and the centrifugal part 310 is arranged between the two guide rails 600 .

[0076] Specifically, Figure 4 As shown, a guide groove 603 is provided on the guide track 600, and mounting parts 302 are respectively provided on both sides of the centrifugal part 310, and the mounting parts 302 are slidably provided in the guide groove 603. A first limiting part 303 is also provided on the centrifugal part 310, and a second limiting part 604 is provided on the guide track 600. The first limiting part 303 and the second limiting part 604 have opposing surfaces to prevent the centrifugal part 310 from falling off the guide track 600 when the centrifugal slider 300 slides toward the outside of the flange body 100.

[0077] Furthermore, an elastic member is installed on the guide rail 600 , and the elastic member is used to provide a restoring force opposite to the direction of the centrifugal force to the centrifugal slider 300 .

[0078] Preferably, the guide track 600 includes a guide rod 601 extending along the sliding direction of the centrifugal slider 300, and a positioning hole is provided on the centrifugal part 310, and the guide rod 601 is inserted into the positioning hole. The elastic member is a spring 602 sleeved on the guide rod 601, and the two ends of the spring 602 are respectively against the surface of the centrifugal part 310 and the guide track 600.

[0079] Specifically, one end of the guide rod 601 is fixed on the surface of the second limit portion 604 facing the first limit portion 303, and the other end is suspended. A positioning hole is provided through the first limit portion 303 of the centrifugal slider 300, and the suspended end of the guide rod 601 is inserted into the positioning hole. The spring 602 is sleeved on the guide rod 601, and the two ends are respectively against the first limit portion 303 and the second limit portion 604.

[0080] When draining, the inner barrel rotates at a certain speed, and the centrifugal slider 300 overcomes the elastic force of the spring 602 under the action of centrifugal force and slides toward the outer side of the flange body 100, thereby pushing the sealing plug body 200 to open the drain port 2 through the driving surface 321. In the process of the inner barrel speed decreasing until it stops rotating, the centrifugal force gradually decreases. When the centrifugal force on the centrifugal slider 300 is less than the elastic force of the spring 602, the spring 602 pushes the first limiter 303 toward the inner side of the flange body 100, causing the centrifugal slider 300 to slide toward the inner side of the flange body 100, and the sealing plug body 200 falls along the driving surface 321 to block the drain port 2.

[0081] In this embodiment, the sealing plug body 200 and the centrifugal slider 300 are integrated on the flange body 100. When used in a washing machine, they can be directly installed under the inner barrel as an integral structure, with a compact structure and small space occupation. The structural design of the centrifugal slider 300 cooperates with the flange body 100, and can increase the mass of the centrifugal part 310 without occupying additional space under the inner barrel. The overall structure is more compact, and can also adapt to the maximum speed that can be achieved by the pulsator washing machine, providing sufficient centrifugal force to open the drain port 2.

[0082] Embodiment 2

[0083] like Figure 3 As shown, the washing machine described in this embodiment includes an inner barrel and the inner barrel flange assembly described in the first embodiment. The flange body 100 is coaxially arranged with the barrel bottom 1 of the inner barrel and fixedly mounted on the barrel bottom 1 of the inner barrel. The barrel bottom 1 of the inner barrel is provided with a drain port 2.

[0084] During the washing / rinsing process, the sealing plug body 200 blocks the drain port 2, so that the inner barrel can independently hold water during the washing / rinsing process.

[0085] During the drainage process, the centrifugal slider 300 slides radially along the flange body 100 under the action of centrifugal force, and the sealing plug body 200 contacts and cooperates with the driving surface 321 and moves accordingly to open the drainage port 2.

[0086] In this embodiment, no dehydration hole is provided on the barrel wall of the inner barrel. During the washing / rinsing process, the sealing plug body 200 blocks the drain port 2 to form a closed inner barrel, so that the inner barrel can independently hold water during the washing / rinsing process. The outer barrel may not be provided in the washing machine, so as to expand the capacity of the inner barrel. When an outer barrel is provided outside the inner barrel, since the inner barrel can independently hold water during the washing / rinsing process, no water is stored between the inner and outer barrels, which saves the amount of washing / rinsing water on the one hand, and avoids the residue of dirt and lint between the inner and outer barrels on the other hand, which is more hygienic.

[0087] The drainage of the inner tub is achieved through the drainage valve assembly integrated on the flange body 100. Specifically, during the washing / rinsing process, the inner tub is in a free state, and the sealing plug body 200 blocks the drainage port 2. When draining, the inner tub is controlled to rotate at a certain speed, thereby generating sufficient centrifugal force to slide the centrifugal slider 300. The centrifugal slider 300 slides radially outward along the flange body 100 under the action of the centrifugal force, and the sealing plug body 200 moves with the driving surface 321 to open the drainage port 2, thereby realizing the drainage function.

[0088] In this embodiment, the inner tub can independently hold water during the washing / rinsing process, and the inner tub drainage function is realized by the sealing plug body 200 and the centrifugal slider 300 integrated on the flange body 100. The inner tub drainage is completed by a purely mechanical structure, eliminating the need for a separate drive motor for draining the inner tub in the prior art, reducing costs, and at the same time, there is no need to position the inner tub before draining, making control simpler. The sealing plug body 200 and the centrifugal slider 300 are integrated on the flange body 100, with a compact structure and small space occupation, which is conducive to the expansion of the inner tub of the washing machine.
