Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, specifically relating to a centrifugal drainage mechanism, a clothes lifting device, and a washing machine. Background Technology

[0002] Washing machines, as one of the most widely used household appliances in daily life, have helped people get rid of the hassle of laundry and brought great convenience. However, washing machines also have certain drawbacks, such as long washing time and high water consumption. With social development, water resources, as an important natural resource, are becoming increasingly important, and people's awareness of water conservation is also increasing. Therefore, how to achieve water-saving functions in washing machines has become particularly important. In addition, since the inner drum is not only used to hold washing water, but also to rotate to tumble and wash the clothes inside, how to design a drainage mechanism suitable for such washing machines has become an urgent problem to be solved.

[0003] Patent application number 201810163972.0 discloses a sealing valve core structure and a self-cleaning washing machine. The sealing valve core structure includes a valve plug corresponding to the drain outlet on the inner drum side wall, and a counterweight block hinged to the upper end of the valve plug. A sealing valve mounting structure is fixedly installed on the inner drum side wall, and a return spring is clamped between the sealing valve mounting structure and the valve plug. The upper end of the counterweight block is provided with a connecting rib extending upward along the axial direction. The upper end of the valve plug protrudes through the top of the mounting sleeve, and the end of the connecting rib is hinged to the upper end of the valve plug.

[0004] While the aforementioned application's self-cleaning washing machine solves the drainage problem of holeless drum washing machines by using a sealing valve for centrifugal drainage, the connection between the end of the connecting rib and the upper end of the valve plug via a shaft and shaft hole causes the sealing valve to be subjected to lateral force due to lever tension. This results in the valve core position not properly corresponding to the drain hole position, leading to valve core failure and affecting the sealing effect of the inner drum.

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

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a centrifugal drainage mechanism for a washing machine. The lever structure and the valve plug component are connected by a ball joint connection structure, which effectively solves the problem that in the existing centrifugal drainage mechanism, the lever structure and the valve plug are connected by a shaft and a shaft hole, and the valve plug component is affected by the lateral force of the lever tension, which makes the position of the valve plug not correspond well with the position of the drain hole, resulting in valve plug failure and affecting the sealing effect.

[0007] To solve the above-mentioned technical problems, the first aspect of this application discloses a centrifugal drainage mechanism for a washing machine, comprising:

[0008] Centrifuge components;

[0009] The valve plug component seals the drain hole of the washing machine under normal conditions;

[0010] The lever structure has one end connected and fixed to the centrifugal component, and the other end connected to the valve plug component through a ball joint connection structure.

[0011] Furthermore, the ball joint connection structure includes a ball joint seat and a ball joint head that is confined within the ball joint seat;

[0012] The ball head seat is fixedly mounted on the lever structure, and the ball head is correspondingly mounted on the valve plug component; or, the ball head seat is fixedly mounted on the valve plug component, and the ball head is correspondingly mounted on the lever structure.

[0013] Furthermore, the valve plug component includes:

[0014] A valve plug that normally seals the drain hole of the washing machine;

[0015] The valve stem has one end connected to the valve plug and the other end connected to the lever structure for limiting. The ball head or ball head seat is fixedly disposed on the end of the valve stem.

[0016] Furthermore, the ball head is a spherical structure, the ball head seat is a hollow hemispherical structure, and the ball head seat has a hemispherical limiting cavity that matches the outer peripheral wall of the ball head.

[0017] Preferably, the ball head seat is fixedly disposed at the end of the lever structure, the ball head is fixedly disposed at the end of the valve stem, and the ball head seat has a ball head seat opening on the side facing the valve plug component, the inner diameter of the ball head seat opening being smaller than the diameter of the ball head.

[0018] Furthermore, the ball head and the valve stem are integrally formed, and the upper end of the valve stem is constructed into a ball-shaped structure to form the ball head;

[0019] Preferably, the ball head is coaxially arranged with the valve stem.

[0020] Furthermore, the ball head seat and the lever structure are integrally formed, and the end of the lever structure that mates with the valve plug component is constructed as a hollow seat structure with an internal cavity to form the ball head seat;

[0021] Preferably, there is a certain gap between the ball head seat and the ball head.

[0022] Furthermore, a limiting protrusion is provided on the peripheral wall of the ball head, and a limiting groove corresponding to the limiting protrusion is provided in the ball head seat.

[0023] A second aspect of this application provides a clothing lifting device, including a lifting rib housing with an internal receiving chamber, wherein the aforementioned centrifugal drainage mechanism is disposed within the lifting rib housing.

[0024] Furthermore, the lifting rib housing is a housing structure with one end open, and the clothing lifting device also includes:

[0025] A cover plate is installed to seal the open end of the lifting rib shell, and the centrifugal drainage mechanism is fixedly installed on the cover plate.

[0026] Preferably, a valve plug mounting seat is fixedly provided on the mounting cover plate, and the valve plug mounting seat is a sleeve structure with an open lower end and a closed upper end;

[0030] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0031] 1. The centrifugal drainage mechanism provided in this application uses a ball-joint connection to limit the connection between the lever structure and the valve plug component. This effectively avoids the problem of existing lever structures and valve plug components being hinged together via shafts and shaft holes, which can cause the valve plug component to be affected by the lateral force of the lever tension, resulting in a misalignment between the valve plug position and the drain hole position, leading to valve plug failure and affecting the sealing effect of the inner cylinder. The valve plug component in the centrifugal drainage mechanism provided in this application is not affected by the lateral force of the lever structure tension. Under normal conditions, the valve plug and drain hole positions always remain aligned without deviation, improving the reliability and sealing performance of the centrifugal drainage mechanism.

The connection and mating of the valve stem and lever structure can be achieved by utilizing the special shapes of their own structures. The structure is simple, easy to implement, and robust and reliable. It does not require connection and fixation through other connecting parts, making the structure of the centrifugal drainage mechanism more simplified.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0055] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] like Figures 1 to 7As shown, the present invention provides a washing machine, including an outer drum 14 and an inner drum 1 coaxially disposed inside the outer drum 14. The inner drum 1 is a non-perforated inner drum with no water permeable holes. It independently holds the washing water when washing clothes, eliminating the need to fill the space between the inner drum 1 and the outer drum 14 with washing / rinsing water, thus greatly reducing the washing water consumption of the washing machine. It also avoids the possibility of dirt adhering between the inner drum 1 and the outer drum 14, greatly improving user health and user experience, and greatly saving water resources.

[0057] The washing machine provided by this invention is a drum washing machine, but it can also be a top-loading washing machine. The washing machine has a casing 11, inside which is an outer drum 14, and an inner drum 1 is coaxially arranged inside the outer drum 14. During the washing process, the inner drum 1 rotates. Preferably, a clothes lifting device 4 is provided inside the inner drum 1 to continuously lift, drop, and tumble the clothes to clean them. The outer drum 14 has a central mounting hole for mounting and fixing a bearing. A motor shaft 7, which is fastened to the inner drum 1, passes through the bearing and is connected to a drive motor 9. The drive motor 9 drives the inner drum 1 to rotate to wash the clothes.

[0058] In this invention, such as Figure 1 As shown, the motor shaft 7 is a hollow shaft. The outlet end of the water inlet pipe 10 of the washing machine is rotatably and sealed to the hollow shaft through a dynamic sealing structure 8, allowing water to enter the inner drum 1 through the motor shaft 7. The inlet end of the water inlet pipe 10 is equipped with a water inlet valve 12 for controlling the opening and closing of the water inlet. The first outlet of the water inlet valve 12 is connected to the water inlet pipe 10, and the second outlet is connected to the detergent dispenser 13 of the washing machine for dispensing additives into the washing machine.

[0059] In this invention, an openable / closeable inner cylinder door 2 is installed on the front opening of the inner cylinder 1, thereby realizing that the inner cylinder 1 is a sealed chamber structure, and an openable / closeable machine door 3 is installed on the casing 11.

[0060] In this invention, the inner drum 1 has a drain hole on its peripheral wall, and the drain hole is equipped with a centrifugal drainage mechanism 5 that normally seals the drain hole. During the spin-drying program and / or the draining program, the washing machine rotates at high speed, and the centrifugal drainage mechanism 5 opens the drain hole under the action of centrifugal force to perform centrifugal drainage.

[0061] The present invention will be further described in detail below with reference to the embodiments.

[0062] Example 1

[0063] like Figures 1 to 7 As shown, this embodiment discloses a centrifugal drainage mechanism 5 for a washing machine, comprising:

[0064] Centrifuge component 51;

[0065] Valve plug component 52, normally seals the drain hole of the washing machine;

[0066] The lever structure 53 is fixedly connected to the centrifugal component 51 at one end, and is limitedly connected to the valve plug component 52 at the other end through a ball joint connection structure.

[0067] The centrifugal drainage mechanism 5 provided in this application has a ball joint connection between the lever structure 53 and the valve plug component 52, which effectively solves the problem that the existing centrifugal drainage mechanism 5 has a hinged connection between the lever structure 53 and the valve plug component 52 through a shaft and shaft hole, which causes the valve plug component 52 to be subjected to the lateral force of the lever tension, and cannot correspond well with the position of the drainage hole, resulting in the failure of the valve plug 521 and affecting the sealing effect.

[0068] Furthermore, the valve plug component 52 normally seals the drain hole. The valve plug component 52 is connected to the centrifugal component 51 through a lever structure 53. Under the action of centrifugal force, the centrifugal component 51 moves in the radial direction of the inner cylinder towards the circumferential wall of the inner cylinder 1. The lever structure 53 has a lever fulcrum in the middle that rotates with the rotating shaft 6, thereby converting the centrifugal motion of the centrifugal component 51 into the movement of the valve plug component 52 in the radial direction of the inner cylinder 1 towards the center of the inner cylinder 1 to open the drain hole and drain water.

[0069] More specifically, such as Figure 3 and Figure 4 As shown, the centrifugal component 51 includes a counterweight of a certain weight, and the lever structure 53 includes a power arm 532 and a resistance arm 533 located on both sides of the lever fulcrum. The power arm 532 is fixedly connected to the centrifugal component 51, and the end of the resistance arm 533 is limited to the valve plug component 52 through the ball joint connection structure. Under the action of centrifugal force, the centrifugal component 51 moves along the radial direction of the inner cylinder 1 towards the circumferential wall of the inner cylinder 1. The centrifugal component 51 presses the end of the resistance arm 533 of the lever structure 53 towards the center of the inner cylinder 1. Under the limiting action of the ball joint connection structure, the valve plug component 52, as the resistance end of the lever structure 53 moves towards the center of the inner cylinder 1, opens the drain hole on the inner cylinder 1 to drain water.

[0070] The centrifugal drainage mechanism 5 provided in this embodiment uses a ball-joint connection structure to limit the connection between the lever structure 53 and the valve plug component 52. This effectively avoids the lateral force of the lever tension on the valve plug component 52, which is caused by the hinged connection between the existing lever structure 53 and the valve plug component 52 via a shaft and shaft hole. This prevents the valve plug component 52 from being affected by the lateral force of the lever tension, causing the position of the valve plug 521 to not correspond well with the position of the drain hole, resulting in the valve plug 521 failing and affecting the sealing effect of the inner cylinder 1. The centrifugal drainage mechanism 5 provided in this application uses a ball-joint connection structure to limit the connection between the lever structure 53 and the valve plug component 52. The valve plug component 52 is not affected by the lateral force of the lever structure 53. Under normal conditions, the position of the valve plug component 52 and the drain hole can always remain in correspondence without deviation, thus improving the reliability and sealing effect of the centrifugal drainage mechanism 5.

[0071] Furthermore, such as Figure 3 and Figure 4 , Figure 7 As shown, the ball joint connection structure includes a ball joint seat 5331 and a ball head 524 limited within the ball joint seat 5331. The ball joint seat 5331 is fixedly disposed on the end of the lever structure 53, and the ball joint seat 5331 has a limiting cavity. The ball head 524 is correspondingly fixedly disposed on the valve plug component 52, and the ball head 524 is limited within the cavity of the ball joint seat 5331 to realize the limiting connection between the lever structure 53 and the valve plug component 52.

[0072] In the above scheme, when the ball head seat 5331 at the end of the lever structure 53 moves towards the center of the inner cylinder 1, it pulls the ball head 524 upward, thereby causing the valve plug component 52 to move upward and open the drain hole on the inner cylinder 1. Since the ball head 524 is confined within the ball head seat 5331, there is no substantial connection between the two. This effectively avoids the problem that the existing centrifugal drainage mechanism 5 lever structure 53 and valve plug component 52 are connected by a hinge, causing the valve plug component 52 to be affected by the lateral pulling force of the lever structure 53, resulting in a misalignment with the drain hole and affecting the sealing effect of the inner cylinder 1.

[0073] Alternatively, in another variation, the ball head seat 5331 is fixedly mounted on the valve plug component 52, and the ball head 524 is correspondingly mounted on the lever structure 53. The ball head 524 on the lever structure 53 is confined within the ball head seat 5331 of the valve plug component 52 to achieve a limiting connection between the lever structure 53 and the valve plug component 52.

[0074] Furthermore, such as Figure 3 , Figure 7As shown, the valve plug component 52 includes: a valve plug 521 that seals the drain hole of the washing machine under normal conditions, and a valve rod 522 whose lower end is connected to the valve plug 521 and whose upper end is limitedly connected to the lever structure 53.

[0075] The upper end of the valve stem 522 is fixedly provided with the ball head 524, and the end of the lever structure 53 is correspondingly provided with the ball head seat 5331; or, the upper end of the valve stem 522 is fixedly provided with the ball head seat 5331, and the end of the lever structure 53 is correspondingly provided with the ball head 524.

[0076] Specifically, such as Figure 3 , Figure 7 As shown, the ball head 524 is a spherical structure with a diameter larger than the outer diameter of the valve stem 522. Alternatively, the ball head 524 can be a spherical structure with a diameter smaller than the outer diameter of the valve stem 522. The ball head seat 5331 is a hollow hemispherical structure with a hemispherical limiting cavity that matches the outer peripheral wall of the ball head 524.

[0077] Preferably, the ball head seat 5331 is fixedly mounted on the lever structure 53, and the ball head 524 is fixedly mounted on the valve plug component 52. The ball head seat 5331 has a ball head seat opening near the valve plug component 52, and the inner diameter of the ball head seat opening is smaller than the diameter of the ball head 524. More preferably, the inner diameter of the ball head seat opening is smaller than the outer diameter of the valve stem 522, and an annular limiting groove is formed at the end connection position of the ball head 524 and the valve stem 522, which is recessed towards the center of the valve stem 522. The edge of the opening of the ball head seat 5331 is limited within the annular limiting groove to prevent the ball head seat 5331 from sliding up and down along the valve stem 522.

[0078] Furthermore, such as Figure 3 , Figure 7 As shown, the bottom of the ball head seat 5331 has a downward-facing ball head seat opening. The inner diameter of the ball head seat opening is smaller than the diameter of the ball head 524 to ensure that the ball head 524 will not detach from the ball head seat 5331 through the ball head seat opening, thus ensuring the reliability of their fit. The ball head 524 includes an upper hemisphere and a lower hemisphere connected to the valve stem 522. The ball head 524 at the upper end of the valve stem 522 can be completely confined within the ball head seat 5331, or at least the upper hemisphere can be confined within the ball head seat 5331. The edge of the ball head seat opening is engaged with the peripheral wall of the lower hemisphere of the ball head 524.

[0079] Furthermore, the upper end of the valve stem 522 is constructed into a ball-shaped structure to form the ball head 524, and the ball head 524 and the valve stem 522 are integrally formed. The upper end of the valve stem 522 is integrally provided with a spherical ball head 524, and the ball head 524 and the valve stem 522 are integrally formed, which is simple to form and easy to process and manufacture.

[0080] Preferably, such as Figure 3 , Figure 7 As shown, the ball head 524 is coaxially arranged with the valve stem 522 to ensure the synchronicity of the movement of the ball head 524 and the valve stem 522 and the balance of the operation of the entire valve plug component 52.

[0081] Furthermore, the end of the lever structure 53 that mates with the valve plug component 52 is configured as a hollow seat structure with an internal cavity to form the ball head seat 5331, preferably, as shown below. Figure 3 As shown, the ball head 524 is coaxially arranged with the valve stem 522 to ensure the synchronicity of the movement of the ball head 524 and the valve stem 522 and the balance of the operation of the entire valve plug component 52.

[0082] Furthermore, the end of the lever structure 53 that mates with the valve plug component 52 is constructed as a hollow seat structure with an internal cavity to form the ball head seat 5331, and the ball head seat 5331 and the lever structure 53 are integrally formed.

[0083] In this embodiment, the upper end of the valve stem 522 is directly constructed into a ball-shaped structure to form the ball head 524, and the end of the lever structure 53 that mates with the valve plug component 52 is directly constructed into a hollow seat structure with an internal cavity to form the ball head seat 5331. The special shapes of the valve stem 522 and the lever structure 53 themselves can be used to achieve the connection and mating between the two. The structure is simple, easy to implement, and firm and reliable. There is no need to connect and fix it through other connecting parts, which makes the structure of the centrifugal drainage mechanism 5 more simplified.

[0084] Preferably, there is a certain movable gap between the ball head seat 5331 and the ball head 524 to ensure that there is a certain fault-tolerant displacement between the lever structure 53 and the valve plug component 52. Even if the lever structure 53 produces a small lateral displacement in its axial direction, it will not generate a lateral pulling force on the valve plug component 52, and will not pull the valve plug 521 off-center, so that the valve plug 521 can still be kept in the position corresponding to the drain hole.

[0085] More preferably, in one embodiment, the ball head 524 is ellipsoidal in shape. A coordinate system is established with the center of the ellipsoidal ball head 524 as the center. The direction parallel to the axial direction of the valve stem 522 is set as the Y-axis, and the direction perpendicular to the axial direction of the valve stem 522 is set as the X-axis. The diameter d1 of the ball head 524 in the Y-axis direction is larger than the diameter d2 in the X-axis direction. The cavity inside the ball head seat 5331 is spherical in shape, and the diameter D of the cavity is set as D. The diameter D of the cavity matches the diameter d1 of the ball head 524 in the Y-axis direction, and the gap between them is less than a set distance L1, where L1 is less than 1 mm. The diameter d2 of the ball head 524 in the X-axis direction is much smaller than the diameter D of the cavity, and the gap between them is greater than a set distance L2, where L2 is greater than 3 mm.

[0086] Through the above design, the ball head seat 5331 and the ball head 524 fit tightly in the axial direction of the valve stem 522. The ball head 524 can move up and down following the ball head seat 5331, carrying the valve plug component 52. There is a certain amount of play space between the ball head 524 and the ball head seat 5331 in the X-axis direction perpendicular to the axial direction of the valve stem 522. This ensures that when the lever structure 53 undergoes a slight lateral displacement in this direction, it will not generate a lateral pulling force on the valve plug component 52, and will not affect the position of the valve plug 521. This further ensures the correspondence between the valve plug 521 and the drain hole, improving the sealing performance.

[0087] Alternatively, in another solution, the cavity inside the ball head seat 5331 can be set to an ellipsoidal shape, and the ball head 524 can be set to a spherical shape, which can also achieve the above-mentioned technical effect. The design principle is the same as the above solution, so it will not be described again here.

[0088] Furthermore, in another embodiment, a limiting protrusion is provided on the peripheral wall of the ball head 524, and a corresponding limiting groove is provided in the ball head seat 5331 to cooperate with the limiting protrusion. The limiting protrusion can be one or multiple protrusions spaced apart along the circumference of the ball head 524. The cooperation between the limiting protrusion and the limiting groove ensures the stability of the fit between the ball head 524 and the ball head seat 5331, preventing relative rotation between them in the circumferential direction.

[0089] In another embodiment, the ball head 524 is hinged to the upper end of the valve stem 522 via a hinge mechanism. The ball head 524 is movably connected to the valve stem 522 via the hinge, which makes the ball head 524 more flexible relative to the valve stem 522, allowing the valve plug component 52 to move more flexibly and smoothly with the lever structure 53.

[0090] The centrifugal drainage mechanism 5 provided in this embodiment has a lever structure 53 and a valve plug component 52 connected by a ball joint connection structure. The valve plug component 52 is not affected by the lateral force of the lever structure 53. Under normal conditions, the position of the valve plug component 52 and the drain hole can always be kept in correspondence and will not deviate, thereby improving the reliability and sealing of the centrifugal drainage mechanism 5.

[0091] like Figures 2 to 4 As shown, this embodiment also provides a clothing lifting device 4, including a lifting rib housing 41 with an internal accommodating chamber, and the centrifugal drainage mechanism 5 described above is provided inside the lifting rib housing 41.

[0092] Furthermore, the lifting rib housing 41 is a housing structure with one end open, and the clothing lifting device 4 also includes:

[0093] The mounting cover 42 is installed to seal the open end of the lifting rib housing 41, and the centrifugal drainage mechanism 5 is fixedly installed on the mounting cover 42.

[0094] Preferably, such as Figure 3 , Figure 7 As shown, a valve plug mounting seat 525 is fixedly provided on the mounting cover plate 42. The valve plug mounting seat 525 is a sleeve structure with an open lower end and a closed upper end. The closed end of the valve plug mounting seat 525 is provided with a through hole that allows the valve stem 522 to move up and down. A compression spring 523 is provided between the valve plug mounting seat 525 and the valve plug 521.

[0095] Under the action of the compression spring 523, the valve plug 521 tightly abuts against and seals the drain hole of the inner cylinder 1. During high-speed dehydration, the centrifugal component 51 is pressed by the centrifugal force, causing the end of the lever structure 53 that cooperates with the valve plug component 52 to move upward. Under the limiting action of the ball head connection structure, the valve plug 521 moves upward, opens the drain hole, and drains water.

[0096] This embodiment also provides a washing machine having the centrifugal drainage mechanism 5 or the clothes lifting device 4 described above.

[0097] like Figures 1 to 4 As shown, the washing machine includes:

[0098] Inner cylinder 1;

[0099] The inner drum door 2 is installed on the opening of the inner drum 1 and can be opened / closed. When the inner drum door 2 is closed, it forms an independent washing chamber together with the inner drum 1, and independently holds the washing water when washing clothes.

[0100] The inner cylinder 1 has a drain hole on its side wall. The clothing lifting device 4 is installed on the inner wall of the inner cylinder 1 located at the drain hole. The centrifugal drainage mechanism 5 can close / open the drain hole.

[0101] Example 2

[0102] like Figures 1 to 4 As shown, this embodiment provides a washing machine clothes lifting device 4. The rotating shaft 6 is fastened to the mounting cover plate 42 by the fixed support 61. This achieves efficient and fast connection and fixation between the rotating shaft 6 and the mounting cover plate 42, while effectively solving the problems of poor reliability and low stability of the existing centrifugal drainage mechanism 5.

[0103] Specifically, this application discloses a clothes lifting device 4 for a washing machine, comprising:

[0104] The lifting rib shell 41 has an open cavity inside;

[0105] The cover plate 42 is installed at the open end of the lifting rib shell 41;

[0106] The centrifugal drainage mechanism 5 includes a centrifugal component 51 and a valve plug component 52 disposed in the lifting housing, and a lever structure 53 connecting the centrifugal component 51 and the valve plug component 52.

[0107] The lever structure 53 has a pivot point in the middle, which is rotatably connected to a shaft 6. The shaft 6 is supported and fixed to the mounting cover plate 42 by a fixed support member 61.

[0108] The washing machine clothes lifting device 4 provided in this embodiment uses a fixed support 61 to fasten the rotating shaft 6 to the mounting cover plate 42. This achieves efficient and rapid assembly and fixing between the rotating shaft 6 and the mounting cover plate 42, while ensuring a firm and reliable connection. It has the advantages of high reliability and high stability, effectively solving the problems of poor reliability and low stability of the existing centrifugal drainage mechanism 5.

[0109] like Figures 2 to 4 As shown, the clothing lifting device 4 provided in this embodiment consists of two parts: a lifting rib housing 41 and a mounting cover plate 42. The two can be connected by screws or bolts and fixing holes to form an integral part. The mounting cover plate 42 or the lifting rib housing 41 is provided with fixing posts or fixing holes. The clothing lifting device 4 is connected to the inner cylinder 1 by screws / bolts. The valve plug component 52 of the centrifugal drainage mechanism 5 provided in the lifting rib housing 41 corresponds to the position of the drainage hole of the inner cylinder 1.

[0110] like Figure 1 , Figure 2 and Figure 4As shown, the lifting rib housing 41 is provided with spray holes 411, so that water is sprayed onto the clothes through the spray holes after being lifted to a height. The lifting rib housing 41 or the mounting cover plate 42 is provided with a water inlet, so that the inside of the lifting rib housing 41 is connected to the internal cavity of the inner cylinder 1.

[0111] Furthermore, such as Figure 3 and Figure 4 As shown, the rotating shaft 6 has a fixing part that mates with the fixing support member 61. The fixing support member 61 is connected and fixed to the fixing part, supporting and fixing the rotating shaft 6 onto the mounting cover plate 42. The fixing part can be a portion of the fixing support member 61, such as a connecting hole on the rotating shaft 6 or a locking platform or slot integrally formed on the rotating shaft 6. The fixing support member 61 can be connected and fixed to the connecting hole, locking platform, or slot to support and fix the rotating shaft 6 onto the mounting cover plate 42.

[0112] Furthermore, such as Figure 3 and Figure 4 As shown, in this embodiment, the fixing support 61 is a screw with an extended length, and the fixing part is a threaded through hole opened on the rotating shaft 6. The screw passes through the threaded through hole to support and fix the rotating shaft 6 at a set height position above the mounting cover plate 42. By using a screw as the fixing support 61 to connect and fix the rotating shaft 6 and the mounting cover plate 42, a fast and efficient assembly connection is achieved, which is easy to disassemble and install. The connection is not only firm and reliable and not easy to loosen, but also has a simple structure, low cost, and is easy to use and promote.

[0113] In the above scheme, the entire rotating shaft 6 can be configured as a columnar structure with a relatively large diameter, which facilitates the opening of the threaded through hole, so that the threaded through hole can be directly opened on the rotating shaft 6. Alternatively, an extension connecting portion can be formed by extending outward from the outer wall of the rotating shaft 6, and the threaded through hole can be opened on the extension connecting portion.

[0114] Furthermore, in this embodiment, both ends of the rotating shaft 6 are rotatably engaged with the lever structure 53, the threaded through hole is located in the middle of the rotating shaft 6, and the screw is fixedly connected to the middle of the rotating shaft 6. Preferably, the middle portion of the rotating shaft 6 is thickened, and the threaded through hole is located in the thickened middle portion of the rotating shaft 6. This design effectively ensures the structural strength of the rotating shaft 6 and effectively avoids problems such as reduced structural strength and easy deformation during use caused by the threaded through hole.

[0115] Furthermore, such as Figure 3 and Figure 4As shown, a bracket 421 is fixedly mounted on the mounting cover plate 42. The bracket 421 has a threaded connection groove 4211 with an extended length that mates with the screw. The screw is connected and fixed within the threaded connection groove 4211. The bracket 421 is a support structure fixedly mounted on the mounting cover plate 42. A cylindrical groove is formed within the support structure corresponding to the position of the screw. The inner wall of the cylindrical groove is threaded to form the threaded connection groove 4211. The inner diameter of the threaded connection groove 4211 matches the outer diameter of the screw. The screw passes through the threaded through hole of the rotating shaft 6, extends into it, and is threaded and fixed within the threaded connection groove 4211.

[0116] In the above scheme, the screw is connected and fixed to the rotating shaft 6 and the mounting cover plate 42 by threaded connection, which not only makes the structure simple and the connection quick and efficient, but also makes the reliability of the entire clothing lifting device 4 higher and has higher stability.

[0117] Preferably, while supporting and fixing the rotating shaft 6, the bracket 421 also supports the middle position of the lever structure 53, thus supporting the lever structure 53. In this embodiment, the upper end face of the bracket 421 has an arc-shaped support surface that matches the lever structure 53. Through the above design, the bracket 421 provides a relatively stable and gentle support force to the lever structure 53. The bracket 421 supports the lever structure 53 from below, sharing part of the weight of the centrifugal component 51 and the lever structure 53. This effectively avoids the situation where the rotating shaft 6 provides all the support for the lever structure 53, causing the rotating shaft 6 to bear excessive pressure and easily break or deform.

[0118] Preferably, the bracket 421 is integrally formed with the mounting cover plate 42. The bracket 421 is a support structure with a certain extension length that is integrally formed on the mounting cover plate 42 by injection molding. The support structure has an extension width that matches the width of the lever structure 53 and is supported below the fulcrum position in the middle of the lever structure 53.

[0119] Furthermore, such as Figure 3 and Figure 4 As shown, the lever structure 53 includes a connecting part 531 located at the central fulcrum position. The connecting part 531 has a pivot hole 534 in the first direction that cooperates with the pivot 6. The connecting part 531 also has a clearance hole 535 in the second direction for avoiding the fixed support member 61.

[0120] Preferably, the first direction is horizontal and the second direction is vertical. The clearance hole 535 is a long strip-shaped clearance hole that is opened vertically through the connecting part 531 to provide sufficient clearance space for the screw.

[0121] In the above scheme, such as Figure 3 and Figure 4 As shown, the clearance hole 535 effectively avoids the screw. The nut at the end of the screw is hidden in the clearance hole 535, preventing the end of the screw from being exposed on the outside of the lever structure 53, which would easily scratch or interfere with the setting of other components. Furthermore, the screw is not visible from the outside through the above design, improving the overall aesthetics.

[0122] When assembling the centrifugal drain valve mechanism, the connecting part 531 of the lever structure 53 can be placed above the bracket 421, ensuring that the threaded connection groove 4211 on the bracket 421 corresponds to the clearance hole 535 on the lever structure 53. Then, the rotating shaft 6 passes through the rotating shaft hole 534 of the lever structure 53, and the screw passes through the threaded through hole of the rotating shaft 6 and is connected and fixed to the threaded connection groove 4211 of the bracket 421, thereby fastening the rotating shaft 6 to the bracket 421. The assembly and connection are simple, efficient, and highly reliable.

[0123] Furthermore, such as Figure 3 and Figure 4 As shown, the connecting part 531 is a thickened connecting part 531 with an enlarged outer diameter in the middle of the lever structure 53. The lever structure 53 also includes a resistance arm 533 and a power arm 532 connected to both sides of the thickened connecting part 531, wherein: the power arm 532 is connected to the centrifugal component 51, and the resistance arm 533 is connected to the valve plug component 52.

[0124] By enlarging the outer diameter of the connecting part 531 to form a thickened connecting part 531, it is easier to open the pivot hole 534 and the clearance hole 535, while effectively ensuring the structural strength of the lever structure 53 itself. This makes the lever structure 53 less prone to deformation during use, increases its durability, and effectively avoids the problem of low strength and poor durability of the lever structure 53 caused by opening the pivot hole 534 and the clearance hole 535.

[0125] Furthermore, the thickened connecting portion 531 is a columnar structure with an enlarged outer diameter and a first extension length L1, and the extension direction of the thickened connecting portion 531 is perpendicular to the swing direction of the lever structure 53.

[0126] The power arm 532 and the resistance arm 533 are plate-shaped structures with a first width H1 respectively connected to both sides of the thickened connecting part 531. The power arm 532 is connected to the lower part of the thickened connecting part 531 near the centrifugal component 51. The power arm 532 is set slightly upward from the thickened connecting part 531 towards the centrifugal component 51 and is fixedly connected to the centrifugal component 51.

[0127] like Figure 3 and Figure 4 As shown, the resistance arm 533 is connected to the upper part of the thickened connecting portion 531 near the valve plug component 52. The resistance arm 533 is slightly inclined downward from the thickened connecting portion 531 towards the valve plug component 52 and is hinged to the valve plug component 52. The entire lever structure 53 forms a combination structure similar to a "6" and a "9" or two overlapping whistle parts. By adopting the above-described structure, the lever structure 53 allows the centrifugal component 51 to more easily drive the valve plug component 52 to move.

[0128] Preferably, the first width H1 = the first extension length L1, the thickness of the power arm 532 gradually decreases from the thickened connecting part 531 towards the centrifugal component 51, the thickness of the resistance arm 533 gradually decreases from the thickened connecting part 531 towards the valve plug component 52, and the end of the power arm 532 or resistance arm 533 connected to the thickened connecting part 531 is relatively thick to ensure the structural strength of the power arm 532 or resistance arm 533. By setting the power arm 532 or resistance arm 533 to a structure with gradually decreasing thickness, the weight of the entire centrifugal drainage mechanism 5 is effectively reduced while saving material costs.

[0129] like Figures 1 to 4 As shown, this embodiment provides a washing machine with the above-mentioned clothes lifting device 4, including: an inner drum 1; an inner drum door 2, which is openable / closeable and installed on the drum opening of the inner drum 1. When the inner drum door 2 is closed, it forms an independent washing chamber with the inner drum 1, and independently holds washing water when washing clothes; a drain hole is provided on the side wall of the inner drum 1, and the clothes lifting device 4 is installed on the drain hole on the inner wall of the inner drum 1. The centrifugal drainage mechanism 5 can close / open the drain hole.

[0130] Example 3

[0131] like Figures 1 to 7As shown, this embodiment provides a washing machine clothes lifting device 4 based on embodiment one. It is mainly to solve the problems in embodiment one, such as the centrifugal component 51 of the centrifugal drainage mechanism 5 being prone to misalignment due to the high speed rotation and vibration of the washing machine, which affects normal drainage, and the long-term misalignment of the centrifugal component 51 causing deformation of the plastic lifting rib shell 41 and resulting in poor appearance fit.

[0132] The clothing lifting device 4 described in this embodiment also includes a centrifugal drainage mechanism 5, which is disposed in the receiving cavity of the lifting rib housing 41 and can be opened for drainage under centrifugal force. In this embodiment, the centrifugal drainage mechanism 5 is fixedly installed on the mounting cover plate 42.

[0133] The centrifugal drainage mechanism 5 includes a centrifugal component 51 and a valve plug component 52. Under the action of centrifugal force, the centrifugal component 51 generates centrifugal motion on the first moving surface, which drives the valve plug component 52 to open the drain hole on the inner drum 1 of the washing machine for drainage.

[0134] like Figures 4 to 7 As shown, the clothing lifting device 4 provided in this embodiment also includes a limiting structure 54 fixedly mounted on the mounting cover plate 42, the limiting structure 54 restricting the centrifugal component 51 from generating offset movement away from the first motion surface.

[0135] In this embodiment, the limiting structure 54 provided on the mounting cover plate 42 restricts the centrifugal component 51 from deviating from the first motion surface, which can effectively prevent the centrifugal component 51 from tilting during the high-speed rotation of the washing machine, thus affecting the normal drainage of the centrifugal drainage mechanism 5.

[0136] Furthermore, the centrifugal component 51 includes a counterweight that moves centrifugally along the first motion surface under the action of centrifugal force. Due to the high-speed rotation and vibration of the washing machine, the position of the counterweight in the clothes lifting device 4 is prone to problems such as skewness, which affects normal drainage. Moreover, long-term skewness of the counterweight can also easily lead to deformation of the plastic lifting ribs, resulting in problems such as poor appearance fit.

[0137] In this embodiment, the limiting structure 54 includes limiting baffles disposed on the left and right sides of the counterweight. By using the limiting baffles disposed on both sides of the counterweight, the position of the counterweight is restricted, which can effectively prevent the counterweight from tilting to the left or right sides under the action of external force.

[0138] Furthermore, such as Figure 5 and Figure 6As shown, the limiting baffle includes a first limiting plate 541 and a second limiting plate 542 fixedly disposed at intervals on the mounting cover plate 42, and a limiting space is formed between the first limiting plate 541 and the second limiting plate 542 for limiting the installation of the counterweight.

[0139] Furthermore, the counterweight includes a first sidewall and a second sidewall located opposite each other on its left and right sides. A first limiting plate 541 is located outside the first sidewall and parallel to it. A second limiting plate 542 is located outside the second sidewall and parallel to it. A certain gap exists between the first limiting plate 541 and the first sidewall, and a certain gap exists between the second limiting plate 542 and the second sidewall, to avoid interfering with the normal centrifugal motion of the counterweight on the first moving surface.

[0140] Preferably, the first moving surface is parallel to the radial direction of the washing machine drum, and the extending direction of the limiting baffle is parallel to the first moving surface, restricting the counterweight block from shifting left or right relative to the first moving surface. The first limiting plate 541 and the second limiting plate 542 restrict the counterweight block from moving on an offset surface perpendicular to the first moving surface.

[0141] Preferably, the first limiting plate 541 and the second limiting plate 542 are integrally injection molded with the mounting cover plate 42. In this embodiment of the invention, the first limiting plate 541 and the second limiting plate 542 are integrally injection molded with the mounting cover plate 42, which simplifies the molding process and reduces manufacturing costs.

[0142] In this embodiment, the first limiting plate 541 and the second limiting plate 542 are integrally formed on the mounting cover plate 42. Compared with being set inside the lifting rib shell 41, they are easier to form and easier to process.

[0143] Furthermore, the clothing lifting device 4 provided in this embodiment also includes a reinforcing structure for increasing the strength of the limiting baffle.

[0144] Preferably, such as Figure 5 and Figure 6 As shown, the reinforcing structure is a reinforcing rib 543 connected between the limiting baffle and the mounting cover plate 42. There are multiple reinforcing ribs 543, which are spaced apart along the length direction of the limiting baffle. Each reinforcing rib 543 includes a first connecting edge and a second connecting edge that are vertically connected. The first connecting edge is connected and fixed to the limiting baffle, and the second connecting edge is connected and fixed to the mounting cover plate 42.

[0145] More preferably, the reinforcing rib 543 is integrally injection molded with the mounting cover plate 42, the first limiting plate 541, and the second limiting plate 542.

[0146] In this embodiment, by setting the first limiting plate 541 and the second limiting plate 542 on the left and right sides of the counterweight, the left and right swaying of the counterweight can be effectively limited, preventing damage to the centrifugal component due to resonance and other reasons, and avoiding problems such as deformation of the plastic lifting rib shell 41 caused by long-term skew of the centrifugal component 51, resulting in poor appearance fit.

[0147] Furthermore, the garment lifting device 4 also includes a positioning structure, which restricts the position of the mounting cover 42 from shifting.

[0148] This embodiment provides a positioning structure within the clothing lifting device 4 to limit the offset of the mounting cover plate 42, thus providing dual protection. This not only prevents the cover plate from shifting within the lifting rib housing 41, but also effectively ensures the stability of the positions of the first limiting plate 541 and the second limiting plate 542, further preventing the counterweight from becoming misaligned.

[0149] Furthermore, such as Figure 5 As shown, the positioning structure includes a first snap-fit ​​wall 561 and a second snap-fit ​​wall 562 fixedly disposed on both sides of the mounting cover plate 42, and the first snap-fit ​​wall 561 and the second snap-fit ​​wall 562 extend along the length direction of the mounting cover plate 42.

[0150] like Figure 5 and Figure 6 As shown, along the length of the mounting cover plate 42, the mounting cover plate 42 includes a first long strip edge and a second long strip edge that are disposed opposite to each other. The first snap-fit ​​wall 561 is disposed on the upper side of the mounting cover plate 42 near the first long strip edge, and the second snap-fit ​​wall 562 is disposed on the upper side of the mounting cover plate 42 near the second long strip edge.

[0151] The first snap-fit ​​wall 561 and the second snap-fit ​​wall 562 can be elongated snap-fit ​​walls extending along the length direction of the mounting cover plate 42, or they can be snap-fit ​​walls spaced apart on the mounting cover plate 42.

[0152] Furthermore, the positioning structure also includes a first abutting wall 551 and a second abutting wall 552 that are correspondingly fixed on both sides of the lifting rib shell 41. The first locking wall 561 is limited and locked in the first abutting wall 551, and the second locking wall 562 is limited and locked in the second abutting wall 552.

[0153] Preferably, the first snap-fit ​​wall 561 and the second snap-fit ​​wall 562 are located near the two side edges of the mounting cover plate 42, and the first abutment wall 551 and the second abutment wall 552 are formed by the side walls on both sides of the lifting rib shell 41.

[0154] Specifically, such as Figure 5 As shown, the lifting rib housing 41 includes a strip-shaped top wall and side walls connected to both sides of the strip-shaped top wall. The first abutting wall 551 and the second abutting wall 552 are formed by the lower edges of the side walls on both sides of the lifting rib housing 41 extending vertically downwards. The first snap-fit ​​wall 561 and the second snap-fit ​​wall 562 are respectively snapped and limited within the side walls on both sides of the lifting rib housing 41.

[0155] The locking and limiting cooperation between the first locking wall 561 and the first abutting wall 551, and the second locking wall 562 and the second abutting wall 552, makes the fit between the mounting cover plate 42 and the lifting rib shell 41 more stable, and enhances the positional stability of the first limiting plate 541 and the second limiting plate 542.

[0156] Furthermore, in another preferred embodiment, the positioning structure further includes a third locking wall 563 and a fourth locking wall 564 disposed on the mounting cover plate 42 at a distance from the first locking wall 561 and at a distance from the second locking wall 562; the third locking wall 563 is located between the first locking wall 561 and the first limiting plate 541, and the fourth locking wall 564 is located between the second locking wall 562 and the second limiting plate 542.

[0157] The positioning structure also includes a third abutment wall 553 and a fourth abutment wall 554 that are fixedly disposed on the inner wall of the lifting rib shell 41. The third locking wall 563 is locked onto the third abutment wall 553, and the fourth locking wall 564 is locked onto the fourth abutment wall 554.

[0158] Furthermore, the third locking wall 563 is at least partially locked to the outside or inside of the third abutment wall 553, and the fourth locking wall 564 is at least partially locked to the outside or inside of the fourth abutment wall 554.

[0159] Preferably, the upper end of the third locking wall 563 is locked to the inner side of the third abutment wall 553, and the upper end of the fourth locking wall 564 is locked to the inner side of the fourth abutment wall 554.

[0160] like Figure 5 As shown, by engaging and limiting the third locking wall 563 with the third abutting wall 553 and the fourth locking wall 564 with the fourth abutting wall 554, the mounting cover plate 42 is more securely locked and limited within the lifting rib housing 41, ensuring that the mounting cover plate 42 will not shift in the horizontal direction. This further guarantees the stability of the positions of the first limiting plate 541 and the second limiting plate 542, and can better limit the offset of the counterweight.

[0161] In the above scheme, the reinforcing rib 543 is integrally connected with the third snap-fit ​​wall 563 and the fourth snap-fit ​​wall 564.

[0162] Specifically, the reinforcing rib 543 is a plate-shaped pentagonal structure. The reinforcing rib 543 includes a bottom reinforcing edge and a first side reinforcing edge and a second side reinforcing edge that are perpendicularly connected to the bottom reinforcing edge. The first side reinforcing edge is connected and fixed to the first limiting plate 541 or the second limiting plate 542, and the second side reinforcing edge is connected and fixed to the second limiting plate 542.

[0163] like Figure 6 As shown, in this embodiment, a plurality of connecting ribs 565 are connected between the first snap-fit ​​wall 561 and the third snap-fit ​​wall 563, and between the second snap-fit ​​wall 562 and the fourth snap-fit ​​wall 564. The plurality of connecting ribs 565 are spaced apart along the length direction of the mounting cover plate 42 between the first snap-fit ​​wall 561 and the third snap-fit ​​wall 563, and between the second snap-fit ​​wall 562 and the fourth snap-fit ​​wall 564. The connecting ribs further enhance the stability of the structure between the first snap-fit ​​wall 561 and the third snap-fit ​​wall 563, and between the second snap-fit ​​wall 562 and the fourth snap-fit ​​wall 564, and avoid shaking or deformation when the lifting rib shell 41 is engaged with the abutment wall.

[0164] Furthermore, the connecting rib 565 is an L-shaped connecting plate that is connected between the first snap-fit ​​wall 561 and the third snap-fit ​​wall 563, and between the second snap-fit ​​wall 562 and the fourth snap-fit ​​wall 564 respectively. By setting the connecting rib 565 to an L shape, the stability of the connection can be guaranteed on the one hand, and the material cost can be reduced on the other hand.

[0165] In another embodiment, a plurality of drain holes are provided on the mounting cover plate 42 located between the first snap-fit ​​wall 561 and the third snap-fit ​​wall 563, and between the second snap-fit ​​wall 562 and the fourth snap-fit ​​wall 564, to prevent a large amount of residual water from accumulating in the grooves formed by the first snap-fit ​​wall 561, the third snap-fit ​​wall 563 and the mounting cover plate 42 between them, or the grooves formed by the second snap-fit ​​wall 562, the fourth snap-fit ​​wall 564 and the mounting cover plate 42 between them, which would prevent the water from draining, thus preventing bacteria growth and affecting the cleaning effect inside the washing machine.

[0166] Preferably, at least one drain hole is provided on the mounting cover plate 42 between each pair of connecting ribs 565 to ensure that the washing water accumulated in the space between each pair of connecting ribs 565 can be drained, and to ensure that there is no possibility of washing water accumulating in any corner of the mounting cover plate 42.

[0167] It should be noted that in the various embodiments of the present invention, the terms "upper end", "lower end", "upward", and "downward" do not indicate that the device or component referred to must have a specific orientation, but are simplified descriptions for ease of description. In this embodiment, the direction closer to the center of the inner cylinder is simplified as "upper end" and "upward", and the direction away from the center of the inner cylinder and closer to the peripheral wall of the inner cylinder is simplified as "lower end" and "downward".
