Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and in particular relates to a centrifugal drainage mechanism of a washing machine and the washing machine. Background Art

[0002] Washing machines, as one of the most widely used household appliances in daily life, have helped people get rid of the trouble of washing clothes and brought great convenience. However, washing machines also have certain disadvantages, such as long washing time and high water consumption. With the development of society, water resources as a key natural resource have become increasingly important, and people's awareness of water conservation has also increased. Therefore, how to achieve water-saving functions in washing machines has become particularly important. In addition, because the inner drum not only holds wash water but also rotates to shake and clean the clothes inside, how to provide a drainage mechanism suitable for such washing machines has become a difficult problem that needs to be solved urgently.

[0003] Patent application number 201810163972.0 discloses a sealing valve core structure and a no-clean washing machine. The sealing valve core structure comprises a valve plug mounted corresponding to a drain port provided on the sidewall of an inner drum, and a counterweight hingedly connected to the upper end of the valve plug. A sealing valve mounting structure is fixedly mounted on the sidewall of the inner drum, with a return spring sandwiched between the sealing valve mounting structure and the valve plug. The upper end of the counterweight is provided with a connecting rib extending axially upward. The upper end of the valve plug extends through the top of the mounting sleeve, and the end of the connecting rib is hingedly connected to the upper end of the valve plug.

[0004] The aforementioned no-clean washing machine proposed in the application solves the drainage problem of hole-free drum washing machines by using a sealing valve for centrifugal drainage. However, because the end of the connecting rib is hingedly connected to the upper end of the valve plug via a shaft and a shaft hole, the sealing valve is subjected to lateral force due to the pull of the lever. This causes the position of the valve core to misalign with the position of the drainage hole, resulting in valve core failure and affecting the sealing effect of the inner drum.

[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 shortcomings of the existing technology and provide a centrifugal drainage mechanism for a washing machine. The lever structure and the valve plug component are connected by a connecting ring, which effectively solves the problem that the lever structure and the valve plug of the existing centrifugal drainage mechanism are hingedly connected by an axis and an axis hole, and the valve plug component is affected by the lateral force of the lever pull, so that the position of the valve plug cannot correspond well with the position of the drainage hole, resulting in failure of the valve plug and affecting the sealing effect.

[0007] To solve the above technical problems, the present application discloses, in a first aspect, a centrifugal drainage mechanism for a washing machine, comprising:

[0008] centrifugal components;

[0009] Valve plug component, which seals the drain hole of the washing machine under normal conditions;

[0010] A lever structure has one end connected to the centrifugal component and the other end connected to the valve plug component via a connecting ring.

[0011] Furthermore, the valve plug component includes:

[0012] valve plug;

[0013] A valve stem, one end of which is connected to the valve plug and the other end of which is provided with a valve stem connection hole;

[0014] The upper end of the connecting ring is suspended on the lever structure, and the lower end passes through the valve stem connecting hole to connect the valve stem to the lever structure.

[0015] Furthermore, a connecting beam is fixedly provided on the end of the lever structure that cooperates with the valve stem;

[0016] The connecting ring has an annular connecting body, which passes through the valve stem connecting hole and is hung on the connecting beam;

[0017] Preferably, a limiting groove is provided on the peripheral wall of the connecting crossbeam to limit the position of the connecting ring, and the connecting ring is suspended in the limiting groove;

[0018] Preferably, a beam connecting hole is provided on the connecting beam, and the connecting ring passes through the valve stem connecting hole and the beam connecting hole respectively.

[0019] Furthermore, the annular connecting body includes an arc-shaped hook portion suspended on the connecting beam and a lifting portion matched with the valve stem connecting hole;

[0020] The arc-shaped hook portion is an arc-shaped rod-shaped structure that matches the curvature of the outer peripheral wall of the connecting beam, and the lifting portion passes through the valve stem connecting hole and is at least partially arranged in a straight rod shape;

[0021] Preferably, the lifting portion includes a straight section located in the middle and a first curved section and a second curved section connected to both ends of the straight section and bent upward.

[0022] Furthermore, the annular connecting body further comprises a first waist connecting section connected between the arc-shaped hooking portion and the first curved section, and a second waist connecting section connected between the arc-shaped hooking portion and the second curved section;

[0023] Preferably, the arc-shaped hooking portion, the first waist connecting section, the pulling portion, and the second waist connecting section are connected end to end to form a long ring-shaped body, and an opening is provided on the first waist connecting section or the second waist connecting section.

[0024] Furthermore, the connecting ring is made of elastic material, and the opening is an elastically deformable opening, and the opening can be opened or closed under the action of its own elasticity;

[0025] Alternatively, the connecting ring is made of a non-elastic material, and after the valve stem is connected to the lever structure, the annular connecting body closes the opening through a closing mechanism.

[0026] Furthermore, the valve stem connecting hole is a through hole opened on the end of the valve stem and extending transversely along the radial direction of the valve stem;

[0027] The valve stem connecting hole includes a cylindrical hole with a constant inner diameter in the middle and tapered holes connected to both ends of the cylindrical hole and gradually expanding from the inside to the outside.

[0028] Furthermore, the end of the lever structure that cooperates with the valve plug component is provided with a notch groove, and the connecting beam is fixedly connected in the notch groove;

[0029] Preferably, the central axis of the valve stem connecting hole intersects with the projection of the connecting beam on the same plane.

[0030] Furthermore, the connecting ring includes multiple layers of nested rings, the innermost nested rings gradually extending outward to the outermost nested rings to form a paper clip structure, and the outermost nested rings are respectively hooked and connected to the lever structure and the valve plug component;

[0031] Alternatively, the connecting ring includes a plurality of ring-shaped chain links, which are connected in series to form a chain-shaped connecting ring, wherein the chain link at the upper end of the connecting ring is connected to the lever structure, and the chain link at the lower end is connected to the valve plug component.

[0032] A second aspect of the present application provides a washing machine having the above-mentioned centrifugal drainage mechanism.

[0033] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0034] The centrifugal drainage mechanism provided by the present application has a lever structure and a valve plug component connected by a hooking connection ring, which effectively avoids the problem that the existing lever structure and the valve plug component are hingedly connected by a shaft and an axis hole, which causes the valve plug component to be affected by the lateral force of the lever pull, resulting in the valve plug position not being well aligned with the position of the drainage hole, causing the valve plug to fail and affecting the sealing effect of the inner cylinder. The valve plug component of the centrifugal drainage mechanism provided by the present application will not be affected by the lateral force of the lever structure pull. Under normal conditions, the position of the valve plug and the drainage hole can always remain aligned and will not deviate, thereby improving the sealing and reliability of the centrifugal drainage mechanism.

[0055] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0056] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0057] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0058] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0059] like Figures 1 to 7As shown, the present invention provides a washing machine, comprising an outer drum 14 and an inner drum 1 coaxially arranged in the outer drum 14. The inner drum 1 is a non-porous inner drum, and the inner drum 1 has no water permeable holes. When washing clothes, washing water is independently held. There is no need to fill washing / rinsing water between the inner drum 1 and the outer drum 14, which greatly reduces the washing water consumption of the washing machine, avoids the possibility of dirt adhesion between the inner drum 1 and the outer drum 14, greatly improves user health and user experience, and greatly saves water resources.

[0060] The washing machine provided by the present invention is a drum washing machine, which may also be a pulsator washing machine. The washing machine comprises a housing 11, within which is an outer drum 14. An inner drum 1 is coaxially disposed within outer drum 14. During the washing process, inner drum 1 rotates. Preferably, a clothing lifting device 4 is disposed within inner drum 1 to continuously lift, drop, and shake the clothing to clean it. Outer drum 14 has a central mounting hole, into which a bearing is mounted and fixed. A motor shaft 7, which is securely connected to inner drum 1, passes through the bearing and is connected to a drive motor 9. The drive motor 9 drives inner drum 1 to rotate and wash the clothing.

[0061] In the present invention, Figure 1 As shown, the motor shaft 7 is a hollow shaft. The outlet end of the washing machine's water inlet pipe 10 is rotatably and hermetically connected to the hollow shaft via a dynamic seal structure 8, allowing water to flow into the inner drum 1 through the motor shaft 7. A water inlet valve 12 is provided at the inlet end of the water inlet pipe 10 for controlling the opening and closing of the water inlet. A first water outlet of the water inlet valve 12 is connected to the water inlet pipe 10, and a second water outlet is connected to a dispenser box 13 of the washing machine for dispensing additives into the washing machine.

[0062] In the present invention, an openable / closable inner cylinder door 2 is installed on the front cylinder opening of the inner cylinder 1, thereby realizing that the inner cylinder 1 is a sealed cabin structure, and an openable / closable machine door 3 is installed on the casing 11.

[0063] In the present invention, a drainage hole is provided on the peripheral wall of the inner drum 1, and a centrifugal drainage mechanism 5 is provided on the drainage hole for sealing the drainage hole under normal conditions. During the dehydration process and / or the drainage process, the washing machine rotates at high speed, and the centrifugal drainage mechanism 5 opens the drainage hole under the action of centrifugal force to perform centrifugal drainage.

[0064] The present invention will be further described in detail below with reference to the embodiments.

[0065] Example 1

[0066] like Figures 3 to 7 As shown, this embodiment discloses a centrifugal drainage mechanism 5 of a washing machine, comprising:

[0067] Centrifugal component 51;

[0068] The valve plug component 52 seals the drain hole of the washing machine under normal conditions;

[0069] One end of the lever structure 53 is connected to the centrifugal component 51 , and the other end is connected to the valve plug component 52 via a connecting ring 57 .

[0070] The centrifugal drainage mechanism 5 provided in the present application has a lever structure 53 and a valve plug component 52 connected by a connecting ring 57, which effectively avoids the problem that the existing lever structure 53 and the valve plug component 52 are hingedly connected by an axis and an axis hole, which will cause the valve plug component 52 to be affected by the lateral force of the lever pull, so that the position of the valve plug 521 does not correspond well to the position of the drainage hole, resulting in failure of the valve plug 521 and affecting the sealing effect of the inner tube 1.

[0071] Furthermore, a drainage hole is provided on the inner cylinder 1, and the valve plug component 52 seals the drainage hole under normal circumstances. 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 cylinder toward the peripheral wall of the inner cylinder 1. The middle part of the lever structure 53 has a lever fulcrum that rotates with the rotating shaft 6, so as to convert the centrifugal motion of the centrifugal component 51 into the valve plug component 52 that moves in the radial direction of the inner cylinder 1 toward the center of the inner cylinder 1 to open the drainage hole for drainage.

[0072] More specifically, if Figure 3 and Figure 4 As shown, the centrifugal component 51 includes a counterweight having 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 connected to the valve plug component 52 via the connecting ring 57. Under the action of centrifugal force, the counterweight moves along the radial direction of the inner cylinder 1 in a direction away from the center of the inner cylinder 1. Under the action of the lever structure 53, the counterweight presses the end of the resistance arm 533 of the lever structure 53 in a direction toward the center of the inner cylinder 1. Under the pull of the connecting ring 57, the valve plug component 52 moves toward the center of the inner cylinder 1 along with the resistance end of the lever structure 53, thereby opening the drainage hole on the inner cylinder 1 for drainage.

[0073] Furthermore, if Figure 3 、 Figure 4 、 Figure 7 As shown, the valve plug component 52 includes:

[0074] Valve plug 521;

[0075] The valve stem 522 has one end connected to the valve plug 521 and the other end is provided with a valve stem connection hole 5221;

[0076] The upper end of the connecting ring 57 is suspended on the lever structure 53 , and the lower end passes through the valve stem connecting hole 5221 to connect the valve stem 522 to the lever structure 53 .

[0077] The centrifugal drainage mechanism 5 provided by the present application has a hook connection between the lever structure 53 and the valve stem 522 via a connecting ring 57, which effectively avoids the problem that the existing lever structure 53 and the valve plug component 52 are hingedly connected via an axis and an axis hole, which would cause the valve plug component 52 to be affected by the lateral force of the lever pull, resulting in the position of the valve plug 521 not being well aligned with the position of the drainage hole, causing the valve plug 521 to fail and affecting the sealing effect of the inner tube 1. The valve plug component 52 of the centrifugal drainage mechanism 5 provided by the present application will not be affected by the lateral force of the lever structure 53 pull. Under normal conditions, the position of the valve plug 521 and the drainage hole can always remain aligned and will not deviate, thereby improving the sealing and reliability of the centrifugal drainage mechanism 5.

[0078] Furthermore, if Figure 3 、 Figure 4 、 Figure 7 As shown, a connecting beam 5331 is fixedly provided on the end of the lever structure 53 that cooperates with the valve stem 522; the connecting ring 57 has an annular connecting body, which passes through the valve stem connecting hole 5221 and is suspended on the connecting beam 5331.

[0079] In one embodiment, the annular connecting body passes through the valve stem connecting hole 5221 and is directly hung on the connecting beam 5331 .

[0080] Preferably, if Figure 3 、 Figure 4 、 Figure 7 As shown, the connecting crossbeam 5331 is provided with a retaining groove on its circumferential wall to engage with the connecting ring 57, and the connecting ring 57 is suspended within the retaining groove. The retaining groove is formed by partially recessing the top wall of the connecting crossbeam 5331 along its width. The retaining groove corresponds to the position of the valve stem connecting hole 5221 and extends in the same direction as the valve stem connecting hole 5221. The retaining groove allows the connecting ring 57 to be mounted on the connecting crossbeam 5331 within the retaining groove, thereby retaining the connecting ring 57 in position and effectively preventing the connecting ring 57 from sliding back and forth on the connecting crossbeam 5331, which could affect the sealing effect of the valve plug 521.

[0081] Alternatively, in another embodiment, the connecting crossbeam 5331 is provided with a crossbeam connection hole, and the connecting ring 57 passes through the valve stem connection hole 5221 and the crossbeam connection hole, respectively. The position of the crossbeam connection hole corresponds to the position of the valve stem connection hole 5221, and the crossbeam connection hole extends in the same direction as the valve stem connection hole 5221. The annular connecting body sequentially passes through the valve stem connection hole 5221 and the crossbeam connection hole, thereby achieving a more secure and stable connection between the valve stem 522 and the lever structure 53.

[0082] Furthermore, the annular connecting body includes an arc-shaped hooking portion 571 suspended on the connecting beam 5331 and a pulling portion 572 matched with the valve stem connecting hole 5221 .

[0083] The arc-shaped hooking portion 571 is an arc-shaped rod-shaped structure that matches the curvature of the outer peripheral wall of the connecting beam 5331 , and the pulling portion 572 passes through the valve stem connecting hole 5221 and is at least partially arranged in a straight rod shape.

[0084] Preferably, the lifting portion 572 includes a straight section in the middle and a first curved section and a second curved section connected to both ends of the straight section and bent upward.

[0085] Furthermore, if Figure 3 、 Figure 7 As shown, the annular connecting body further includes a first waist connecting section 573 connected between one end of the arc-shaped hooking portion 571 and the first curved section, and a second waist connecting section 574 connected between the other end of the arc-shaped hooking portion 571 and the second curved section.

[0086] Preferably, the arc-shaped hooking portion 571 , the first waist connecting section 573 , the pulling portion 572 , and the second waist connecting section 574 are sequentially connected end to end to form a long strip annular structure similar to a water drop shape, forming the connecting ring 57 .

[0087] In this embodiment, Figure 3 、 Figure 4 、 Figure 7 As shown, an opening 575 is provided on the first waist connecting section 573 or the second waist connecting section 574 .

[0088] Furthermore, in one embodiment, the connecting ring 57 is made of elastic material, and the opening 575 is an elastically deformable opening 575 , and the opening 575 can be opened or contracted and closed under the action of its own elasticity.

[0089] For example, the connecting ring 57 can be made of materials such as spring steel, elastic engineering plastics such as PEEK, etc. When the connecting ring 57 connects the valve stem 522 and the lever structure 53, the opening 575 can be elastically deformed and opened. After the connecting ring 57 passes through the valve stem connecting hole 5221 and is hung on the connecting beam 5331, the opening 575 of the connecting ring 57 recovers its deformation under the action of its own elasticity and automatically shrinks and closes, effectively preventing the connecting beam 5331 or the valve stem 522 from detaching from the connecting ring 57 through the opening 575, so that the lever structure 53 is disconnected from the valve plug component 52.

[0090] Alternatively, in another embodiment, the connecting ring 57 is made of a non-elastic material, and after the valve stem 522 is connected to the lever structure 53 , the annular connecting body closes the opening 575 through a closing mechanism.

[0091] For example, the connecting ring 57 can be made of non-elastic materials such as stainless steel and brass. In one embodiment, after the connecting ring 57 passes through the valve stem connecting hole 5221 and is connected to the connecting beam 5331, a closing tool is used to achieve permanent deformation of the ring opening 575 to force closure.

[0092] Alternatively, in another embodiment, the closing mechanism includes a connecting rod, also provided with a connecting rod and a positive projection on one end of the annular connecting body located at the opening 575, and a negative projection on the other end of the annular connecting body. One end of the connecting rod is hinged to the annular connecting body, and the other end of the connecting rod is provided with a positive latching groove and a negative latching groove corresponding to the positive projection and the negative projection, respectively. The connecting rod can be buckled in a positive or negative manner so that the positive latching groove and the negative latching groove respectively engage with the positive projection and the negative projection, thereby opening or closing the opening 575 of the connecting ring 57. This structure is simple and easy to use.

[0093] Furthermore, the valve stem connection hole 5221 is a through-hole extending transversely through the end of the valve stem 522 along the radial direction of the valve stem 522. The valve stem connection hole 5221 comprises a cylindrical hole with a constant inner diameter in the middle, and tapered holes at both ends of the cylindrical hole that gradually expand outward from the inside. By increasing the inner diameters at both ends of the valve stem connection hole 5221, the connecting ring 57 can be smoothly and quickly inserted into the valve stem connection hole 5221, improving assembly efficiency.

[0094] In the above scheme, the lifting portion 572 of the annular connecting body is inserted into the valve stem connecting hole 5221, the outer diameter of the straight section of the lifting portion 572 matches the inner diameter of the cylindrical hole of the valve stem connecting hole 5221, the straight section is limited to the cylindrical hole, and the first curved section and the second curved section are located in the conical hole.

[0095] Furthermore, a notch groove is provided at the end of the lever structure 53 that cooperates with the valve plug component 52, and the connecting beam 5331 is fixedly connected in the notch groove.

[0096] Preferably, the central axis of the valve stem connecting hole 5221 intersects with the projection of the connecting beam 5331 on the same horizontal plane. More preferably, the central axis of the valve stem connecting hole 5221 is perpendicular to the projection of the connecting beam 5331 on the same horizontal plane.

[0097] Furthermore, in one embodiment, the connecting ring 57 may include multiple layers of nested rings, with the innermost nested rings gradually extending outward to the outermost nested rings to form a paperclip-like structure, with the outermost nested rings respectively hooked and connected to the lever structure 53 and the valve plug component 52. The connecting ring 57 may be formed from a single piece of metal wire bent into a paperclip-like structure. By configuring the connecting ring 57 to resemble a paperclip, the structural strength of the connecting ring 57 is increased, and the problem of the valve stem 522 or the connecting crossbeam 5331 being easily separated from the connecting ring 57 is eliminated, thereby achieving a more stable connection.

[0098] Alternatively, in another embodiment, the connecting ring 57 includes a plurality of ring-shaped links, which are connected in series to form a chain-like connecting ring 57. The upper link of the connecting ring 57 is connected to the lever structure 53, and the lower link is connected to the valve plug component 52. The upper link can be directly mounted on the connecting beam 5331 or hooked on the beam connection hole, and the lower link can pass through the valve stem connection hole 5221. By configuring the connecting ring 57 as a chain-like structure, the flexibility and adaptability of the entire connecting ring 57 can be increased. At the same time, during assembly and connection, one or more links can be appropriately added or deleted according to actual needs to adjust the length of the entire connecting ring 57 to meet different usage requirements.

[0099] like Figures 1 to 4 As shown, this embodiment further provides a clothing lifting device 4, comprising a lifting rib shell 41 with a accommodating chamber therein, wherein the centrifugal drainage mechanism 5 is disposed in the lifting rib shell 41.

[0100] Furthermore, the lifting rib housing 41 is a housing structure with one end open, and the clothing lifting device 4 further includes:

[0101] The installation cover plate 42 is sealed at the open end of the lifting rib housing 41 , and the centrifugal drainage mechanism 5 is fixedly installed on the installation cover plate 42 .

[0102] Preferably, if Figure 3 and Figure 4As 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 for 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.

[0103] The valve plug 521 is tightly abutted against and sealed on the drainage hole of the inner drum 1 under the action of the compression spring 523. During high-speed dehydration, the centrifugal component 51 presses the end of the lever structure 53 that cooperates with the valve plug component 52 to move upward under the action of the centrifugal force. The valve plug 521 moves upward under the drive of the connecting ring 57, opens the drainage hole, and drains water.

[0104] This embodiment also provides a washing machine having the above-mentioned centrifugal drainage mechanism 5 or the above-mentioned clothes lifting device 4.

[0105] like Figures 1 to 4 As shown, the washing machine comprises:

[0106] Inner tube 1;

[0107] The inner drum door 2 is openably mounted 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 to independently hold washing water when washing clothes.

[0108] A drainage hole is provided on the side wall of the inner drum 1 , the clothing lifting device 4 is mounted on the inner wall of the inner drum 1 at the drainage hole, and the centrifugal drainage mechanism 5 can close / open the drainage hole.

[0109] Example 2

[0110] like Figures 1 to 4 As shown, this embodiment provides a clothes lifting device 4 for a washing machine on the basis of the first embodiment, wherein the rotating shaft 6 is fastened to the mounting cover 42 by means of a fixed support 61, thereby achieving efficient and rapid connection and fixation between the centrifugal drainage mechanism 5 and the mounting cover 42, and effectively solving the problems of poor reliability and low stability of the existing centrifugal drainage mechanism 5.

[0111] Specifically, the present application discloses a clothes lifting device 4 for a washing machine, comprising:

[0112] The lifting rib housing 41 has an open cavity inside;

[0113] Install the cover plate 42, which is installed on the open end of the lifting rib housing 41;

[0114] 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 connected between the centrifugal component 51 and the valve plug component 52;

[0115] The lever structure 53 has a pivot point in the middle thereof. The pivot point is rotatably connected to a shaft 6 . The shaft 6 is supported and fixed on the mounting cover 42 via a fixing support 61 .

[0116] The clothes lifting device 4 for the washing machine provided in this embodiment fastens the rotating shaft 6 to the mounting cover 42 by means of a fixed support 61, thereby achieving efficient and rapid assembly and fixation between the rotating shaft 6 and the mounting cover 42, and providing a firm and reliable connection, with the advantages of high reliability and high stability, and effectively solving the problems of poor reliability and low stability of the existing centrifugal drainage mechanism 5.

[0117] 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 42. The two parts can be connected by screws or bolts and fixing holes to form an integrated component. The mounting cover 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 drum 1 via screws or bolts. The valve plug component 52 of the centrifugal drainage mechanism 5, located within the lifting rib housing 41, corresponds to the position of the drainage hole in the inner drum 1.

[0118] like Figure 1 、 Figure 2 and Figure 4 As shown, the lifting rib housing 41 is provided with a spray hole 411, which enables the lifting water to be sprayed on the clothes through the spray hole after being lifted up. The lifting rib housing 41 or the mounting cover 42 is provided with a water inlet, which enables the interior of the lifting rib housing 41 to communicate with the internal chamber of the inner drum 1.

[0119] Furthermore, if Figure 3 and Figure 4 As shown, the rotating shaft 6 has a fixing portion that cooperates with the fixing support 61. The fixing support 61 is connected and fixed to the fixing portion, supporting and fixing the rotating shaft 6 on the mounting cover 42. The fixing portion can be a partial structure of the fixing support 61, such as a connecting hole defined on the rotating shaft 6 or a fixture or slot integrally provided on the rotating shaft 6. The fixing support 61 can be connected and fixed to the connecting hole, fixture, or slot to support and fix the rotating shaft 6 on the mounting cover 42.

[0120] Furthermore, if Figure 3 and Figure 4As shown, in this embodiment, the fixing support member 61 is a screw having an extended length, and the fixing portion is a threaded through-hole formed in the rotating shaft 6. The screw passes through the threaded through-hole to support and fix the rotating shaft 6 at a set height above the mounting cover 42. By using a screw as the fixing support member 61 to connect and fix the rotating shaft 6 and the mounting cover 42, a fast and efficient assembly connection is achieved, and disassembly and installation are easy. Not only is the connection secure and reliable, and not prone to loosening, but the structure is simple, the cost is low, and it is easy to use and promote.

[0121] In the above solution, the entire shaft 6 can be configured as a columnar structure with a relatively large diameter to facilitate the formation of the threaded through hole, so that the threaded through hole can be directly formed on the shaft 6. Alternatively, the outer wall of the shaft 6 can be extended outward to form an extended connecting portion, and the threaded through hole can be formed on the extended connecting portion.

[0122] Furthermore, in this embodiment, the ends of the rotating shaft 6 are rotatably engaged with the lever structure 53, the threaded through-hole is provided in the middle of the rotating shaft 6, and the screw support 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 provided in the thickened middle portion of the rotating shaft 6. This arrangement effectively ensures the structural strength of the rotating shaft 6 and effectively avoids problems such as reduced structural strength of the rotating shaft 6 and easy deformation during use caused by the threaded through-hole.

[0123] Furthermore, if Figure 3 and Figure 4 As shown, a bracket 421 is fixedly mounted on the mounting cover 42. A threaded connection groove 4211 extending in length is provided within the bracket 421, which mates with the screw. The screw is secured within the threaded connection groove 4211. The bracket 421 is a support structure fixed to the mounting cover 42. A cylindrical groove is defined within the support structure at a position corresponding to 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 extends through the threaded through-hole of the rotating shaft 6 through the rear end and is threadedly secured within the threaded connection groove 4211.

[0124] In the above solution, the screw rod is connected and fixed to the rotating shaft 6 and the mounting cover plate 42 by threaded connection, which not only has a simple structure and fast and efficient connection, but also makes the entire clothing lifting device 4 more reliable and has higher stability.

[0125] Preferably, while supporting and fixing the rotating shaft 6, the bracket 421 is also supported at the middle position of the lever structure 53 to support the lever structure 53. In this embodiment, the upper end face of the bracket 421 has an arc-shaped supporting surface that cooperates with the lever structure 53. Through the above design, the bracket 421 provides a relatively stable and gentle supporting force for the lever structure 53. The bracket 421 is supported below the lever structure 53 to share part of the weight of the centrifugal component 51 and the lever structure 53, effectively avoiding the rotating shaft 6 providing all the support for the lever structure 53, so that the rotating shaft 6 is under too much pressure and is prone to breakage or deformation.

[0126] Preferably, the bracket 421 is integrally arranged with the mounting cover 42. The bracket 421 is a pillar structure with a certain extended length that is arranged on the mounting cover 42 by integral injection molding, and the pillar structure has an extended 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.

[0127] Furthermore, if Figure 3 and Figure 4 As shown, the lever structure 53 includes a connecting portion 531 located at the middle fulcrum position, the connecting portion 531 is provided with a rotating shaft hole 534 that cooperates with the rotating shaft 6 in the first direction, and the connecting portion 531 is provided with an avoidance hole 535 in the second direction for avoiding the fixed support member 61.

[0128] Preferably, the first direction is the horizontal direction, the second direction is the vertical direction, and the avoidance hole 535 is a through hole with a long cross section that is opened on the connecting portion 531 from top to bottom, providing sufficient avoidance space for the screw.

[0129] In the above scheme, if Figure 3 and Figure 4 As shown, the avoidance hole 535 is provided to effectively avoid the screw, and the nut at the end of the screw is hidden in the avoidance hole 535 to prevent the end of the screw from being exposed to the outside of the lever structure 53, which may cause scratches with other components or interfere with the settings of other components. In addition, the screw cannot be seen from the outside due to the above design, thereby improving the overall aesthetics.

[0130] When assembling the centrifugal drain valve mechanism, the connection part 531 of the lever structure 53 can be placed above the bracket 421 to ensure that the threaded connection groove 4211 on the bracket 421 corresponds to the avoidance hole 535 on the lever structure 53. Then, the rotating shaft 6 is passed through the rotating shaft hole 534 of the lever structure 53, and the screw is passed through the threaded through hole of the rotating shaft 6 to connect and fix it with the threaded connection groove 4211 of the bracket 421, so that the rotating shaft 6 is fastened to the bracket 421. The assembly connection is simple, efficient and reliable.

[0131] Furthermore, if Figure 3 and Figure 4 As shown, the connecting portion 531 is a thickened connecting portion 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 on both sides of the thickened connecting portion 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.

[0132] By enlarging the outer diameter of the connecting portion 531 to form a thickened connecting portion 531, it is convenient to provide the rotating shaft hole 534 and the avoidance hole 535, while effectively ensuring the structural strength of the lever structure 53 itself, so that the lever structure 53 is not easily deformed during use, thereby increasing durability, and effectively avoiding the problem of low strength and poor durability of the lever structure 53 due to the provision of the rotating shaft hole 534 and the avoidance hole 535.

[0133] Furthermore, the thickened connecting portion 531 is a columnar structure with an enlarged outer diameter and a first extension length L1 , and an extension direction of the thickened connecting portion 531 is perpendicular to the swing direction of the lever structure 53 .

[0134] The power arm 532 and the resistance arm 533 are plate-like structures connected on both sides of the thickened connection part 531 and have a first width H1 respectively, wherein: the power arm 532 is connected to the lower part of the thickened connection part 531 on the side close to the centrifugal component 51, and the power arm 532 is slightly inclined upward from the thickened connection part 531 to the direction close to the centrifugal component 51, and is fixedly connected to the centrifugal component 51.

[0135] like Figure 3 and Figure 4 As shown, the resistance arm 533 is connected to the upper portion of the thickened connecting portion 531 near the valve plug 52. The resistance arm 533 is arranged at a slight downward angle from the thickened connecting portion 531 toward the valve plug 52 and is hingedly connected to the valve plug 52. The entire lever structure 53 forms a structure similar to a "6" and a "9" or two whistle parts stacked together. This structural arrangement of the lever structure 53 allows the centrifugal component 51 to more easily drive the valve plug 52.

[0136] Preferably, the first width H1 = the first extension length L1, the thickness of the power arm 532 gradually decreases from the thickened connection part 531 toward the direction close to the centrifugal component 51, and the thickness of the resistance arm 533 gradually decreases from the thickened connection part 531 toward the direction close to the valve plug component 52. The end of the power arm 532 or the resistance arm 533 connected to the thickened connection part 531 is set to be relatively thick to ensure the structural strength of the power arm 532 or the resistance arm 533. The power arm 532 or the resistance arm 533 is set to a structure with gradually decreasing thickness, which saves material costs and effectively reduces the weight of the entire centrifugal drainage mechanism 5.

[0137] Example 3

[0138] like Figures 1 to 7 As shown, this embodiment provides a clothes lifting device 4 for a washing machine on the basis of the first embodiment, mainly to solve the problems in the first embodiment, that the centrifugal component 51 of the centrifugal drainage mechanism 5 is easily deflected due to the high-speed rotation and vibration of the washing machine, thereby affecting normal drainage, and that the centrifugal component 51 is deflected for a long time, resulting in deformation of the lifting rib shell 41 made of plastic, resulting in poor appearance and other problems.

[0139] The clothes lifting device 4 of this embodiment further includes a centrifugal drainage mechanism 5 , which is disposed in the accommodation chamber of the lifting rib housing 41 and can be opened to drain water under the action of centrifugal force. The centrifugal drainage mechanism 5 of this embodiment is fixedly mounted on the mounting cover 42 .

[0140] The centrifugal drainage mechanism 5 includes a centrifugal component 51 and a valve plug component 52. The centrifugal component 51 generates centrifugal motion on the first motion surface under the action of centrifugal force, driving the valve plug component 52 to open the drainage hole on the inner drum 1 of the washing machine to drain water.

[0141] like Figures 4 to 7 As shown, the clothing lifting device 4 provided in this embodiment further includes a limiting structure 54 fixedly provided on the mounting cover 42 , and the limiting structure 54 limits the centrifugal component 51 from generating an offset motion away from the first motion surface.

[0142] In this embodiment, a limiting structure 54 is provided on the mounting cover 42 to limit the centrifugal component 51 from producing an offset movement away from the first motion surface, thereby effectively preventing the centrifugal component 51 from being skewed during high-speed rotation of the washing machine, thereby affecting the normal drainage of the centrifugal drainage mechanism 5.

[0143] Furthermore, the centrifugal component 51 includes a counterweight block that performs centrifugal motion 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 block in the clothing lifting device 4 is very likely to be skewed, affecting normal drainage. In addition, long-term deflection of the counterweight block is also likely to cause deformation of the lifting ribs made of plastic material, resulting in problems such as poor appearance.

[0144] In this embodiment, the limiting structure 54 includes limiting baffles arranged on the left and right sides of the counterweight block. By limiting the position of the counterweight block by the limiting baffles arranged on both sides of the counterweight block, the counterweight block can be effectively prevented from being deflected to the left or right by external force.

[0145] Furthermore, if Figure 5 and Figure 6 As shown, the limiting baffle includes a first limiting plate 541 and a second limiting plate 542 fixedly arranged at intervals on the installation cover 42, and a limiting space for the limiting installation of the counterweight block is formed between the first limiting plate 541 and the second limiting plate 542.

[0146] Furthermore, the counterweight includes a first sidewall and a second sidewall disposed opposite each other on its left and right sides. A first limiting plate 541 is located outside the first sidewall and parallel to the first sidewall of the counterweight. A second limiting plate 542 is located outside the second sidewall and parallel to the second sidewall of the counterweight. A certain gap is provided between the first limiting plate 541 and the first sidewall, and a certain gap is provided between the second limiting plate 542 and the second sidewall to avoid interfering with the normal centrifugal motion of the counterweight on the first motion surface.

[0147] 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, limiting the left and right deviation of the counterweight relative to the first moving surface. The first limiting plate 541 and the second limiting plate 542 limit the movement of the counterweight in an offset plane perpendicular to the first moving surface.

[0148] Preferably, the first and second limiting plates 541, 542 are integrally injection molded with the mounting cover 42. In the embodiment of the present invention, the first and second limiting plates 541, 542 are integrally injection molded with the mounting cover 42, which has a simple molding process and low manufacturing cost.

[0149] In this embodiment, the first limiting plate 541 and the second limiting plate 542 are integrally formed on the installation cover plate 42 , which is easier to form and more convenient to manufacture than being arranged in the lifting rib shell 41 .

[0150] Furthermore, the clothing lifting device 4 provided in this embodiment also includes a reinforcing structure for increasing the strength of the limiting baffle.

[0151] Preferably, if 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. The 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.

[0152] More preferably, the reinforcing rib 543 is integrally formed with the mounting cover plate 42 , the first limiting plate 541 , and the second limiting plate 542 by injection molding.

[0153] This embodiment can effectively limit the left and right swing of the counterweight block by providing the first limit plate 541 and the second limit plate 542 on the left and right sides of the counterweight block, thereby preventing the centrifugal component from being damaged due to resonance and other reasons, and avoiding the long-term deflection of the centrifugal component 51, which may cause the plastic lifting rib shell 41 to be deformed, resulting in poor appearance and other problems.

[0154] Furthermore, the clothing lifting device 4 further includes a positioning structure, which limits the position of the installation cover 42 from being offset.

[0155] This embodiment provides a positioning structure in the clothing lifting device 4 to limit the displacement of the installation cover plate 42, thereby playing a double protection role. While avoiding the displacement of the packaging cover plate in the lifting rib shell 41, it also effectively ensures the stability of the position of the first limit plate 541 and the second limit plate 542, further avoiding the deviation of the position of the counterweight block.

[0156] Furthermore, if Figure 5 As shown, the positioning structure includes a first clamping wall 561 and a second clamping wall 562 fixedly arranged on both sides of the installation cover plate 42 , and the first clamping wall 561 and the second clamping wall 562 are extended along the length direction of the installation cover plate 42 .

[0157] like Figure 5 and Figure 6 As shown, along the length direction of the mounting cover plate 42, the mounting cover plate 42 includes a first long edge and a second long edge arranged opposite to each other, the first clamping wall 561 is arranged on the upper side of the mounting cover plate 42 close to the first long edge, and the second clamping wall 562 is arranged on the upper side of the mounting cover plate 42 close to the second long edge.

[0158] The first clamping wall 561 and the second clamping wall 562 may be long strip-shaped clamping walls extending along the length direction of the installation cover plate 42 , or may be clamping walls spaced apart on the installation cover plate 42 .

[0159] Furthermore, the positioning structure also includes a first retaining wall 551 and a second retaining wall 552 fixedly arranged on both sides of the lifting rib shell 41, the first clamping wall 561 is limited and clamped in the first retaining wall 551, and the second clamping wall 562 is limited and clamped in the second retaining wall 552.

[0160] Preferably, the first clamping wall 561 and the second clamping wall 562 are arranged near the edges of both sides of the installation cover 42 , and the first retaining wall 551 and the second retaining wall 552 are formed by the side walls on both sides of the lifting rib shell 41 .

[0161] Specifically, if Figure 5 As shown, the lifting rib housing 41 includes a strip-shaped top wall and side walls connected to the strip-shaped top wall. The first retaining wall 551 and the second retaining wall 552 are formed by vertically extending downward from the lower edges of the side walls on both sides of the lifting rib housing 41. The first clamping wall 561 and the second clamping wall 562 are respectively clamped and retained within the side walls on both sides of the lifting rib housing 41.

[0162] Through the clamping and limiting cooperation between the first clamping wall 561 and the first retaining wall 551, and the second clamping wall 562 and the second retaining wall 552, the cooperation between the mounting cover plate 42 and the lifting rib shell 41 is more stable, and the position stability of the first limiting plate 541 and the second limiting plate 542 can be enhanced.

[0163] Furthermore, in another preferred embodiment, Figure 5 As shown, the positioning structure also includes a third clamping wall 563 arranged on the mounting cover plate 42 and spaced apart from the first clamping wall 561, and a fourth clamping wall 564 arranged and spaced apart from the second clamping wall 562; the third clamping wall 563 is located between the first clamping wall 561 and the first limiting plate 541, and the fourth clamping wall 564 is located between the second clamping wall 562 and the second limiting plate 542.

[0164] The positioning structure also includes a third retaining wall 553 and a fourth retaining wall 554 fixedly arranged on the inner wall of the lifting rib shell 41 , the third clamping wall 563 is limitedly clamped on the third retaining wall 553 , and the fourth clamping wall 564 is limitedly clamped on the fourth retaining wall 554 .

[0165] Furthermore, the third engaging wall 563 is at least partially engaged with the outer side or inner side of the third retaining wall 553 , and the fourth engaging wall 564 is at least partially engaged with the outer side or inner side of the fourth retaining wall 554 .

[0166] Preferably, the upper end of the third clamping wall 563 is limitedly clamped on the inner side of the third retaining wall 553 , and the upper end of the fourth clamping wall 564 is limitedly clamped on the inner side of the fourth retaining wall 554 .

[0167] like Figure 5 As shown, by coordinating the third clamping wall 563 with the third retaining wall 553, and the fourth clamping wall 564 with the fourth retaining wall 554, the mounting cover plate 42 is more firmly clamped and limited in the lifting rib shell 41, so that the mounting cover plate 42 will not be offset in the horizontal direction, further ensuring the stability of the position of the first limiting plate 541 and the second limiting plate 542, and can better limit the offset of the counterweight block.

[0168] In the above solution, the reinforcing rib 543 is connected to the third clamping wall 563 and the fourth clamping wall 564 and is integrally provided.

[0169] Specifically, the reinforcing rib 543 is a plate-shaped pentagonal structure, and the reinforcing rib 543 includes a bottom reinforcing edge and a first side reinforcing edge and a second side reinforcing edge perpendicularly connected to the bottom reinforcing edge, wherein 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.

[0170] like Figure 6 As shown, in this embodiment, a plurality of connecting ribs 565 are connected between the first clamping wall 561 and the third clamping wall 563, and between the second clamping wall 562 and the fourth clamping wall 564. The plurality of connecting ribs 565 are arranged at intervals along the length direction of the mounting cover 42 between the first clamping wall 561 and the third clamping wall 563, and between the second clamping wall 562 and the fourth clamping wall 564. The connecting ribs are arranged to further enhance the structural stability between the first clamping wall 561 and the third clamping wall 563, and between the second clamping wall 562 and the fourth clamping wall 564, thereby avoiding shaking and deformation when the supporting wall of the lifting rib shell 41 cooperates.

[0171] Furthermore, the connecting rib 565 is an L-shaped connecting plate respectively connected between the first clamping wall 561 and the third clamping wall 563, and the second clamping wall 562 and the fourth clamping wall 564. By setting the connecting rib 565 to an L shape, on the one hand, the stability of its connection can be guaranteed, and on the other hand, the material cost can be reduced.

[0172] In another embodiment, a plurality of drainage holes are provided at intervals on the mounting cover plate 42 located between the first clamping wall 561 and the third clamping wall 563, and between the second clamping wall 562 and the fourth clamping wall 564, to prevent a large amount of residual water from accumulating in the groove formed by the first clamping wall 561, the third clamping wall 563 and the mounting cover plate 42 therebetween, or in the groove formed by the second clamping wall 562, the fourth clamping wall 564 and the mounting cover plate 42 therebetween, which cannot be discharged and breeds bacteria, thereby affecting the cleaning effect inside the washing machine.

[0173] Preferably, at least one drain hole is provided on the installation cover plate 42 between every two connecting ribs 565 to ensure that the washing water accumulated in the space between every two connecting ribs 565 can be discharged, ensuring that there is no possibility of washing water accumulation in any corner position in the installation cover plate 42.

[0174] It should be noted that in the various embodiments of the present invention, the "upper end", "lower end", "upward" and "downward" do not indicate that the device or element referred to must have a specific orientation, but are simplified descriptions for the convenience of description.
