Description

Technical Field

[0001] This invention relates to the field of laundry equipment technology, and more specifically, to a clothes lifting device for a washing machine and a washing machine. Background Technology

[0002] In existing drum washing machines, the outer drum holds water while the inner drum rotates and washes. The inner drum has holes in its wall for introducing washing water or for spin-drying the clothes inside. However, the washing water flows between the inner and outer drums for extended periods, causing dirt and scale to accumulate between them, leading to bacterial growth and secondary contamination of clothes, seriously threatening consumer health. Furthermore, the water filling the space between the inner and outer drums is a waste of water. Therefore, perforated drum washing machines have been designed. Since the inner drum not only holds washing water but also rotates to tumble and wash the clothes, designing a suitable spin-drying and drainage structure for this type of washing machine has become a pressing problem.

[0003] Chinese invention patent application No. 201711260471.6 discloses a washing machine. The inner drum of the washing machine is a container that is sealed after the opening is fastened by the door. The inner drum is a conical tube with unequal sizes at one end of the bottom and one end of the opening. Multiple lifting ribs are provided on the side wall of the inner drum. The lifting ribs are hollow inside and connected to the inside of the inner drum. At least one drain port is provided at the large end of the inner drum and is connected to the hollow part of the lifting rib. A sealing valve is provided at the drain port and is located inside the lifting rib. When the inner drum rotates at high speed, the valve body of the sealing valve moves along the axial direction of the inner drum towards the middle of the inner drum under the action of centrifugal force to open the drain port provided at the end of the inner drum.

[0004] The self-cleaning washing machine proposed in the above application solves the drainage problem of the non-porous drum washing machine by using a sealing valve for centrifugal drainage. However, it has the following defects: due to the high-speed rotation and vibration of the washing machine, the position of the counterweight of the sealing valve is prone to skew, which affects normal drainage. Furthermore, the long-term skew of the counterweight can also cause deformation of the plastic lifting ribs, resulting in poor appearance and other problems.

[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 clothes lifting device for washing machines and a washing machine. The present invention restricts the centrifugal component from deviating from the first motion surface by setting a limiting structure, which can effectively prevent the position of the centrifugal component from deviating during the high-speed rotation of the washing machine, thus preventing problems such as affecting the normal drainage of the centrifugal drainage mechanism.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A clothes lifting device for a washing machine, comprising:

[0009] The shell has a cavity that is open at one end;

[0010] A sealing baffle is used to seal the open end of the housing;

[0011] A centrifugal drainage mechanism is disposed within a housing, and the centrifugal drainage mechanism includes a centrifugal component capable of generating centrifugal motion on a first moving surface;

[0012] It also includes a limiting structure disposed on the encapsulation baffle, the limiting structure restricting the centrifugal component from generating offset movement away from the first motion surface.

[0013] It also includes a limiting structure disposed on the encapsulation baffle, the limiting structure restricting the centrifugal component from generating offset movement away from the first motion surface.

[0014] Furthermore, the centrifugal component includes a counterweight that moves centrifugally along a first motion surface under the action of centrifugal force, and the limiting structure includes limiting baffles disposed on the left and right sides of the counterweight.

[0015] 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 displacement of the counterweight relative to the first moving surface.

[0016] Furthermore, the limiting baffle includes a first limiting plate and a second limiting plate fixedly disposed at intervals on the encapsulation baffle, and a limiting space is formed between the first limiting plate and the second limiting plate for limiting the installation of the counterweight.

[0017] Preferably, the first limiting plate and the second limiting plate are integrally injection molded with the encapsulation baffle.

[0018] Furthermore, the counterweight includes a first sidewall and a second sidewall arranged opposite to each other on the left and right sides;

[0019] The first limiting plate is located outside the first side wall, and the second limiting plate is located outside the second side wall. There is a certain gap distance between the first limiting plate and the first side wall, and between the second limiting plate and the second side wall.

[0020] Furthermore, it also includes a reinforcing structure for increasing the strength of the limiting baffle;

[0021] Preferably, the reinforcing structure is a reinforcing rib connected between the limiting baffle and the encapsulation baffle.

[0022] Furthermore, it also includes a positioning structure that restricts the position of the encapsulation baffle from shifting.

[0023] Furthermore, the positioning structure includes a first snap-fit ​​wall and a second snap-fit ​​wall fixedly disposed on both sides of the encapsulation baffle;

[0024] The positioning structure also includes a first abutment wall and a second abutment wall fixedly disposed on both sides of the housing, the first snap-fit ​​wall being limited and snapped into the first abutment wall, and the second snap-fit ​​wall being limited and snapped into the second abutment wall.

[0025] Preferably, the first snap-fit ​​wall and the second snap-fit ​​wall are located near the two side edges of the encapsulation baffle, and the first abutting wall and the second abutting wall are formed by the side walls on both sides of the housing.

[0026] Furthermore, the positioning structure also includes a third latching wall and a fourth latching wall that are spaced apart from the first latching wall and spaced apart from the second latching wall on the encapsulation baffle.

[0027] The positioning structure also includes a third abutment wall and a fourth abutment wall fixedly disposed on the inner wall of the housing. The third snap-fit ​​wall is limited and snap-fitted onto the third abutment wall, and the fourth snap-fit ​​wall is limited and snap-fitted onto the fourth abutment wall.

[0028] Furthermore, the third locking wall is at least partially locked onto the outside or inside of the third abutment wall, and the fourth locking wall is at least partially locked onto the outside or inside of the fourth abutment wall.

[0029] Preferably, the upper end of the third locking wall is locked to the inside of the third abutment wall, and the upper end of the fourth locking wall is locked to the inside of the fourth abutment wall.

[0030] Another object of the present invention is to provide a washing machine having the above-described clothes lifting device, comprising:

[0031] The inner drum holds the washing water separately when washing clothes, and a drain outlet is provided on the side wall;

[0032] A clothes lifting device is installed on the inner wall of the inner drum, corresponding to the position of the drain outlet;

[0033] The centrifugal drainage mechanism is installed on the encapsulation baffle of the clothing lifting device to block and close the drain outlet. Under the action of centrifugal force, the centrifugal drainage mechanism can open the drain outlet to drain water.

[0034] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0035] 1. The present invention, by setting a limiting structure on the encapsulation baffle, restricts the centrifugal component from deviating from the first motion surface, which can effectively prevent the position of the counterweight of the centrifugal component from becoming skewed during the high-speed rotation of the washing machine, thus affecting the normal drainage of the centrifugal drainage mechanism.

[0036] 2. The present invention provides a positioning structure within the garment lifting device to limit the displacement of the encapsulation baffle, thus providing dual protection. This not only prevents the encapsulation cover from shifting within the housing but also effectively ensures the stability of the positions of the first and second limiting plates, further preventing the counterweight from becoming misaligned.

[0037] 3. In this invention, the first limiting plate and the second limiting plate are set on the packaging baffle, which makes them easier to process and manufacture. Furthermore, they are processed by integral injection molding with the packaging baffle, which simplifies the molding process and increases production efficiency.

[0059] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0060] 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.

[0061] Example 1

[0062] like Figures 1 to 5As shown, an embodiment of the present invention provides a washing machine clothes lifting device 5, including: a housing 50 having a cavity with one open end; and an encapsulation baffle 60 sealing the open end of the housing 50 to form an installation chamber 501 within the clothes lifting device 5 for installing a centrifugal drainage mechanism 70, a lint filter, etc.

[0063] Furthermore, the garment lifting device 5 also includes a centrifugal drainage mechanism 70, which is installed in the receiving cavity of the housing 50 and can be opened to drain water under centrifugal force. Preferably, in this embodiment, the centrifugal drainage mechanism 70 is fixedly installed on the encapsulation baffle 60.

[0064] The centrifugal drainage mechanism 70 includes a centrifugal component 71 and a valve plug component 72. Under the action of centrifugal force, the centrifugal component 71 generates centrifugal motion on the first moving surface, which drives the valve plug component 72 to open the drain port 401 on the inner drum 40 of the washing machine for drainage.

[0065] The clothing lifting device 5 provided in this embodiment also includes a limiting structure 62 fixedly disposed on the encapsulation baffle 60, the limiting structure 62 restricting the centrifugal component 71 from generating offset movement away from the first motion surface.

[0066] In this embodiment, the limiting structure 62 provided on the encapsulation baffle 60 restricts the centrifugal component 71 from deviating from the first motion surface, which can effectively prevent the counterweight block 711 of the centrifugal component 71 from tilting during the high-speed rotation of the washing machine, thus affecting the normal drainage of the centrifugal drainage mechanism 70.

[0067] Furthermore, the centrifugal component 71 includes a counterweight 711 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 711 in the clothes lifting device 5 is prone to problems such as skewness, which affects normal drainage. In addition, the long-term skewness of the counterweight 711 can also easily lead to deformation of the plastic lifting ribs, resulting in problems such as poor appearance fit.

[0068] In this embodiment, the limiting structure 62 includes limiting baffles disposed on the left and right sides of the counterweight 711. By using the limiting baffles disposed on both sides of the counterweight 711, the position of the counterweight 711 is restricted, which can effectively prevent the counterweight 711 from tilting to the left or right sides under the action of external force.

[0069] Furthermore, the limiting baffle includes a first limiting plate 621 and a second limiting plate 622 fixedly disposed at intervals on the encapsulation baffle 60, and a limiting space is formed between the first limiting plate 621 and the second limiting plate 622 for the limiting installation of the counterweight block 711.

[0070] Furthermore, the counterweight 711 includes a first sidewall and a second sidewall located opposite to each other on its left and right sides. A first limiting plate 621 is located outside the first sidewall and parallel to it. A second limiting plate 622 is located outside the second sidewall and parallel to it. A certain gap exists between the first limiting plate 621 and the first sidewall, and between the second limiting plate 622 and the second sidewall, to avoid interfering with the normal centrifugal motion of the counterweight 711 on the first moving surface.

[0071] 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 offset of the counterweight 711 relative to the first moving surface. The first limiting plate 621 and the second limiting plate 622 limit the movement of the counterweight 711 on the offset surface perpendicular to the first moving surface.

[0072] Preferably, the first limiting plate 621 and the second limiting plate 622 are integrally injection molded with the encapsulation baffle 60. In this embodiment of the invention, the first limiting plate 621 and the second limiting plate 622 are integrally injection molded with the encapsulation baffle 60, which simplifies the molding process and reduces manufacturing costs.

[0073] In this embodiment, the first limiting plate 621 and the second limiting plate 622 are integrally formed on the encapsulation baffle 60. Compared with being set inside the housing 50, this is easier to form and easier to process.

[0074] Furthermore, the clothing lifting device 5 provided in this embodiment also includes a reinforcing structure for increasing the strength of the limiting baffle.

[0075] Preferably, the reinforcing structure is a reinforcing rib 623 connected between the limiting baffle and the encapsulation baffle 60. There are multiple reinforcing ribs 623, which are spaced apart along the length direction of the limiting baffle. Each reinforcing rib 623 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 encapsulation baffle 60.

[0076] More preferably, the reinforcing rib 623 is integrally injection molded with the encapsulation baffle 60 and the limiting baffle.

[0077] Furthermore, the garment lifting device 5 also includes a positioning structure, which restricts the position of the encapsulation baffle 60 from shifting.

[0078] This embodiment provides a positioning structure within the clothing lifting device 5 to limit the offset of the encapsulation baffle 60, thus providing dual protection. This not only prevents the encapsulation cover from shifting within the housing 50, but also effectively ensures the stability of the positions of the first limiting plate 621 and the second limiting plate 622, further preventing the counterweight 711 from becoming misaligned.

[0079] Furthermore, such as Figure 2 As shown, the positioning structure includes a first snap-fit ​​wall 631 and a second snap-fit ​​wall 632 fixedly disposed on both sides of the encapsulation baffle 60, and the first snap-fit ​​wall 631 and the second snap-fit ​​wall 632 extend along the length direction of the encapsulation baffle 60.

[0080] like Figure 2 and Figure 3 As shown, along the length of the encapsulation baffle 60, the encapsulation baffle 60 includes a first long strip edge and a second long strip edge disposed opposite to each other. The first snap-fit ​​wall 631 is disposed on the upper side of the encapsulation baffle 60 near the first long strip edge, and the second snap-fit ​​wall 632 is disposed on the upper side of the encapsulation baffle 60 near the second long strip edge.

[0081] The first snap-fit ​​wall 631 and the second snap-fit ​​wall 632 can be elongated snap-fit ​​walls extending along the length direction of the encapsulation baffle 60, or they can be snap-fit ​​walls spaced apart on the encapsulation baffle 60.

[0082] Furthermore, the positioning structure also includes a first abutment wall 541 and a second abutment wall 542 that are fixedly disposed on both sides of the housing 50. The first snap-fit ​​wall 631 is limited and snap-fitted into the first abutment wall 541, and the second snap-fit ​​wall 632 is limited and snap-fitted into the second abutment wall 542.

[0083] Preferably, the first snap-fit ​​wall 631 and the second snap-fit ​​wall 632 are located near the two side edges of the encapsulation baffle 60, and the first abutment wall 541 and the second abutment wall 542 are formed by the side walls on both sides of the housing 50.

[0084] Specifically, such as Figure 2 As shown, the housing 50 includes a strip-shaped top wall 51 and side walls 52 connected to both sides of the strip-shaped top wall 51. The first abutting wall 541 and the second abutting wall 542 are formed by the lower edges of the side walls 52 on both sides of the housing 50 extending vertically downwards. The first snap-fit ​​wall 631 and the second snap-fit ​​wall 632 are respectively snapped and limited within the side walls on both sides of the housing 50.

[0085] The engagement and limiting cooperation between the first snap-fit ​​wall 631 and the first abutment wall 541, and between the second snap-fit ​​wall 632 and the second abutment wall 542, makes the fit between the encapsulation baffle 60 and the housing 50 more stable, and enhances the positional stability of the first limiting plate 621 and the second limiting plate 622.

[0086] Furthermore, in another preferred embodiment, the positioning structure further includes a third latching wall 633 and a fourth latching wall 634 disposed on the encapsulation baffle 60 at a distance from the first latching wall 631 and at a distance from the second latching wall 632; the third latching wall 633 is located between the first latching wall 631 and the first limiting plate 621, and the fourth latching wall 634 is located between the second latching wall 632 and the second limiting plate 622.

[0087] The positioning structure also includes a third abutment wall 543 and a fourth abutment wall 544 that are fixedly disposed on the inner wall of the housing 50. The third locking wall 633 is locked onto the third abutment wall 543, and the fourth locking wall 634 is locked onto the fourth abutment wall 544.

[0088] Furthermore, the third locking wall 633 is at least partially locked to the outside or inside of the third abutment wall 543, and the fourth locking wall 634 is at least partially locked to the outside or inside of the fourth abutment wall 544.

[0089] Preferably, the upper end of the third locking wall 633 is locked to the inner side of the third abutment wall 543, and the upper end of the fourth locking wall 634 is locked to the inner side of the fourth abutment wall 544.

[0090] like Figure 2 As shown, by engaging and limiting the third snap-fit ​​wall 633 with the third abutment wall 543 and the fourth snap-fit ​​wall 634 with the fourth abutment wall 544, the encapsulation baffle 60 is more securely snapped and limited within the housing 50, so that the position of the encapsulation baffle 60 will not shift in the horizontal direction, further ensuring the stability of the positions of the first limiting plate 621 and the second limiting plate 622, and playing a better role in limiting the offset of the counterweight 711.

[0091] In the above scheme, the reinforcing rib 623 is integrally connected with the third snap-fit ​​wall 633 and the fourth snap-fit ​​wall 634.

[0092] Specifically, the reinforcing rib 623 is a plate-shaped pentagonal structure. The reinforcing rib 623 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 621 or the second limiting plate 622, and the second side reinforcing edge is connected and fixed to the second limiting plate 622.

[0093] like Figure 3 As shown, in this embodiment, a plurality of connecting ribs 635 are connected between the first snap-fit ​​wall 631 and the third snap-fit ​​wall 633, and between the second snap-fit ​​wall 632 and the fourth snap-fit ​​wall 634. The plurality of connecting ribs 635 are spaced apart along the length direction of the encapsulation baffle 60 between the first snap-fit ​​wall 631 and the third snap-fit ​​wall 633, and between the second snap-fit ​​wall 632 and the fourth snap-fit ​​wall 634. The connecting ribs further enhance the stability of the structure between the first snap-fit ​​wall 631 and the third snap-fit ​​wall 633, and between the second snap-fit ​​wall 632 and the fourth snap-fit ​​wall 634, and avoid shaking or deformation when the housing 50 is engaged with the abutment wall.

[0094] Furthermore, the connecting rib 635 is an L-shaped connecting plate between the first snap-fit ​​wall 631 and the third snap-fit ​​wall 633, and between the second snap-fit ​​wall 632 and the fourth snap-fit ​​wall 634 respectively. By setting the connecting rib 635 to an L-shape, the stability of the connection can be ensured on the one hand, and the material cost can be reduced on the other hand.

[0095] In another embodiment, the encapsulation baffle 60 located between the first snap-fit ​​wall 631 and the third snap-fit ​​wall 633, and between the second snap-fit ​​wall 632 and the fourth snap-fit ​​wall 634, is provided with a plurality of drainage holes at intervals. This prevents a large amount of residual water from accumulating in the grooves formed by the first snap-fit ​​wall 631, the third snap-fit ​​wall 633 and the encapsulation baffle 60 between them, or the grooves formed by the second snap-fit ​​wall 632, the fourth snap-fit ​​wall 634 and the encapsulation baffle 60 between them, which would prevent the water from draining, thus preventing bacteria growth and affecting the cleaning effect inside the washing machine.

[0096] Preferably, at least one drain hole is provided on the encapsulation baffle 60 between each pair of connecting ribs 635 to ensure that the washing water accumulated in the space between each pair of connecting ribs 635 can be drained, and to ensure that there is no possibility of washing water accumulating in any corner of the encapsulation baffle 60.

[0097] like Figure 1 , Figure 4 , Figure 5 As shown, this embodiment also provides a washing machine having the above-mentioned clothes lifting device 5, including:

[0098] The inner drum 40 is used to hold washing water independently when washing clothes, and a drain outlet 401 is provided on the side wall.

[0099] The clothing lifting device 5 is installed on the inner wall of the inner cylinder 40 at the position corresponding to the drain outlet 401;

[0100] The centrifugal drainage mechanism 70 is installed inside the housing 50 of the clothing lifting device 5 to block and close the drain outlet 401. Under the action of centrifugal force, the centrifugal drainage mechanism 70 can open the drain outlet 401 to drain water.

[0101] Example 2

[0102] This embodiment provides a clothes lifting device 5 for a washing machine based on embodiment one. It is mainly to solve the problem that the counterweight of the centrifugal drainage mechanism set in the shell is prone to hitting other parts and generating noise when it is in centrifugal motion.

[0103] like Figures 1 to 8 As shown, this embodiment provides a clothes lifting device 5 for a washing machine, including:

[0104] The housing 50 has a cavity with one end open;

[0105] Centrifugal drainage mechanism 70, located inside housing 50, includes centrifugal component 71 and valve plug component 72 connected to centrifugal component 71;

[0106] The centrifugal component 71 includes a counterweight 711 that can generate centrifugal motion under the action of centrifugal force. The centrifugal motion of the counterweight 711 drives the valve plug component 72 to move.

[0107] The cavity of the housing 50 has an installation chamber 501 for installing the centrifugal drainage mechanism 70, and a buffer structure is provided in the installation chamber 501 and / or on the counterweight 711.

[0108] The washing machine clothes lifting device 5 provided by the present invention effectively avoids the phenomenon of noise caused by the counterweight 711 impacting the inner drum 40 or the side wall of the installation chamber 501 during centrifugal motion, which affects the user experience, by setting a buffer structure in the installation chamber 501 inside the housing 50 and / or on the counterweight 711. At the same time, the buffer structure can also protect the counterweight 711 and extend the service life of the centrifugal drainage mechanism 70.

[0109] Furthermore, a sealing baffle 60 is installed inside the housing 50 near the open end, and the sealing baffle 60 divides the cavity of the housing 50 to form an installation chamber 501 for installing the centrifugal component 71.

[0110] like Figure 1-8 As shown, the centrifugal drainage mechanism 70 provided in this embodiment includes a centrifugal component 71 and a valve plug component 72. The centrifugal component 71 includes a counterweight 711 and a connecting rod 712. The counterweight 711 includes a counterweight shell and a counterweight 711 disposed inside the counterweight shell.

[0111] By adding a counterweight shell around the counterweight 711, the counterweight 711 is enclosed, effectively preventing the counterweight 711 from directly contacting the washing water and thus avoiding rust and corrosion, which could affect the normal operation of the centrifugal drainage mechanism 70. At the same time, the counterweight shell also provides some protection, preventing damage to the counterweight 711 during centrifugal motion.

[0112] like Figure 4 , Figure 5 as well as Figure 8 As shown, one end of the connecting rod 712 of the centrifugal drainage mechanism 70 is rotatably connected to the counterweight shell 711, and the other end is rotatably connected to the valve plug component 72. The middle part of the connecting rod 712 is rotatably supported and fixed, forming a lever structure. The connecting rod 712 is connected and fixed to the counterweight shell outside the counterweight 711, which is easier to process and shape than directly connecting and fixing to the counterweight 711. Under the action of centrifugal force, the counterweight 711 generates centrifugal motion, which drives the valve plug component 72 to open the drain port 401 on the inner cylinder 40 for drainage.

[0113] like Figures 4 to 8 As shown, the centrifugal component 71 is disposed within the mounting chamber 501 located above the encapsulation baffle 60. The buffer structure includes a first molding structure 604 recessed outward on the encapsulation baffle 60 corresponding to the position of the counterweight 711. The recessed first molding structure 604 on the encapsulation baffle 60 provides a larger buffer space for the downward movement of the counterweight 711, avoiding the phenomenon of the counterweight 711 impacting the encapsulation baffle 60 and generating excessive noise due to limited movement space.

[0114] Furthermore, the first molding structure 604 includes a molding peripheral wall and a molding bottom wall 6044 protruding from the lower surface of the encapsulation baffle 60. The shape and size of the molding bottom wall 6044 are adapted to the cross-sectional shape and size of the counterweight 711. The first molding structure 604 provides sufficient buffer space for the entire counterweight 711, protecting the counterweight 711 while preventing it from impacting the encapsulation baffle 60 and generating noise.

[0115] Furthermore, the centrifugal drainage mechanism 70 also includes a valve plug component 72 connected to the counterweight 711 via a lever structure. The counterweight 711 generates centrifugal motion under the action of centrifugal force, which drives the valve plug component 72 to open the drain port 401 on the inner cylinder 40 for drainage.

[0116] like Figure 6 and Figure 7As shown, the first pressed structure 604 extends near the valve plug component 72 and is provided with a buffer cone angle 6043 for avoiding the lever structure. The cross-section of the first pressed structure 604 is similar to that of a pencil tip. The first pressed structure 604 is provided with a apex structure that gradually slopes towards the valve plug component 72, corresponding to the position of the lever structure, forming the buffer cone angle 6043. The buffer cone angle 6043 can avoid the lever structure, allowing the first pressed structure 604 to provide a larger buffer space for the counterweight 711.

[0117] Furthermore, such as Figure 6 , Figure 7 As shown, the buffer structure also includes a chamfered structure 7113 on the side of the counterweight 711 away from the valve plug component 72. The chamfered structure 7113 is formed by the notched corner of the end of the counterweight 711 away from the valve plug component 72, which can provide a larger buffer space for the falling of the counterweight 711, so as to ensure that the centrifugal drainage mechanism 70 has enough room to move to open or close the drain port 401.

[0118] Preferably, in this embodiment, as Figure 4 , Figure 5 , Figure 8 As shown, the counterweight 711 is in the shape of a quadrangular prism, and the buffer notch is a chamfered structure 7113 below the end of the counterweight 711 away from the valve plug component 72. The chamfered structure 7113 has an inclined wall surface extending from the bottom wall of the counterweight 711 to the left end wall of the counterweight 711.

[0119] Furthermore, such as Figure 4 , Figure 8 As shown, the buffer structure also includes a first buffer pad 713 disposed outside the bottom wall of the counterweight 711. The first buffer pad 713 can be made of rubber material and has good elasticity. The first buffer pad 713 satisfies the design requirements of buffering and protecting the counterweight 711.

[0120] The first buffer pad 713 can cover the entire bottom wall of the counterweight 711, and the first buffer pad 713 can be fixed to the counterweight 711 by means of adhesive or snap-fit.

[0121] Preferably, the bottom wall of the counterweight 711 includes a flat wall and an inclined wall formed by the chamfered structure 7113. In order to save materials, the first buffer pad 713 is disposed between the flat wall and the inclined wall.

[0122] Because the junction of the flat wall and the inclined wall will first contact the encapsulation baffle 60 when the counterweight 711 falls, the above design covers the junction of the flat wall and the inclined wall within the first buffer pad 713, which effectively buffers and protects against shocks while minimizing the amount of material used.

[0123] Alternatively, in another embodiment, the first buffer pad 713 is disposed outside the inclined wall of the chamfered structure 7113, and the first buffer pad 713 has a certain elastic stretching thickness.

[0124] Furthermore, such as Figures 4 to 7 As shown, the buffer structure also includes a second buffer pad 6041 disposed on the bottom wall 6044 of the first molding structure 604. The second buffer pad 6041 is disposed on the bottom wall 6044, so that when the counterweight 711 falls, the first buffer pad 713, the second buffer pad 6041, and the first molding structure 604 will all play an effective role in buffering and shock absorption, thereby achieving the purpose of shock absorption and noise reduction for the counterweight 711 from multiple angles.

[0125] Preferably, a buffer pad mounting position is provided on the molded bottom wall 6044 at the junction of the chamfered structure 7113 of the counterweight 711 and the bottom wall of the counterweight 711. The second buffer pad 6041 is embedded in the buffer pad mounting position. The upper surface of the second buffer pad 6041 is slightly higher than the upper surface of the molded bottom wall 6044, or flush with it.

[0126] The buffer pad mounting position can be a through mounting hole opened in the bottom wall of the molded structure 6044, or a blind hole. The second annular pad 6041 is embedded and pressed into the buffer pad mounting position. The second buffer pad will not occupy the falling space of the counterweight 711. At the same time, when the space of the first molded structure 604 cannot provide enough buffer space for the counterweight 711, the second buffer pad 6041 will play its role, providing a larger buffer space for the counterweight 711. At the same time, even if the counterweight 711 hits the second buffer pad 6041, it will not generate much noise, further improving the buffering and noise reduction effect of the buffer structure.

[0127] Furthermore, such as Figures 4 to 7 As shown, one or more spaced drainage holes 6042 are provided on the bottom wall of the first molding structure 604. If washing water accumulates in the mounting chamber 501 of the housing 50, it can be drained in time through the drainage holes 6042. At the same time, since the molding bottom wall 6044 of the first molding structure 604 is the lowest position of the entire mounting chamber 501, it is more conducive to the water flow to collect and be discharged by opening the drainage holes 6042 on the molding bottom wall 6044 of the first molding structure 604.

[0128] Preferably, a one-way valve is installed in the drain hole 6042. The one-way valve allows water in the installation chamber 501 to be discharged through the drain hole 6042, but water in the inner cylinder 40 cannot enter the installation chamber 501 through the drain hole 6042, thus further ensuring the sealing effect of the installation chamber 501.

[0129] Furthermore, in another extended embodiment, the top wall 51 of the housing 50 is provided with a second pressing structure protruding upwards at the position corresponding to the counterweight 711. The buffer structure also includes a second pressing structure that provides buffer space for the counterweight 711 to rise. The second pressing structure effectively prevents the counterweight 711 from impacting the top wall 51 of the housing 50 and generating significant noise during centrifugal motion.

[0130] Furthermore, through the second compression structure, the initial position of the counterweight 711 can be raised accordingly, which is equivalent to providing a larger buffer space for the fall of the counterweight 711.

[0131] Example 3

[0132] This embodiment provides an improved clothes lifting device for washing machines based on Embodiment 1. The main purpose is to solve the problem that the centrifugal drainage mechanism installed in the existing clothes lifting device is prone to the accumulation and entanglement of lint on its components, which causes the centrifugal drainage mechanism to not close properly or to fail to drain normally.

[0133] like Figure 1-8 As shown, this embodiment provides a clothes lifting device 5 for a washing machine. The cavity of the housing 50 has an independently enclosed installation chamber 501, and the centrifugal drainage mechanism 70 is at least partially installed in the installation chamber 501.

[0134] like Figure 4 , Figure 5 , Figure 8 As shown, since the housing 50 is provided with an inlet 521 for the washing water in the inner drum 40 to flow into the housing 50, the cavity of the housing 50 is connected to the inside of the inner drum 40. However, the centrifugal drainage mechanism 70 is directly installed in the cavity of the housing 50. During the washing process, lint inevitably enters the housing 50 with the water flow and then enters the centrifugal drainage mechanism 70.

[0135] In this embodiment, the centrifugal drainage mechanism 70 is installed in an additional, independently enclosed installation chamber 501 within the cavity of the housing 50. This installation chamber 501 serves to prevent wire debris from entering the centrifugal drainage mechanism 70. Wire debris inside the inner cylinder 40 will not enter the installation chamber 501 with the water flow, thus placing the centrifugal drainage mechanism 70 in a debris-free environment. This fundamentally avoids the possibility of wire debris adhering and tangling, effectively ensuring the reliability of the centrifugal drainage mechanism 70's operation.

[0136] Furthermore, multiple partitions are fixedly installed inside the housing 50, which divide the housing 50 into an independently enclosed installation chamber 501. The partitions can be integrally injection molded with the housing 50 to form the independently enclosed installation chamber 501; or, the partitions can be integrally connected with the housing 50 via connectors to form the independently enclosed installation chamber 501.

[0137] Specifically, the partition includes a partition baffle that forms a mounting chamber 501 with a lower opening in the cavity of the partition housing 50, and an encapsulation baffle 60 that is encapsulated on the lower opening of the partition baffle to form an independently enclosed mounting chamber 501. The centrifugal component 71 of the centrifugal drainage mechanism 70 is disposed in the mounting chamber 501.

[0138] By using a partition baffle and a sealing baffle 60 provided inside the housing 50, an independent and enclosed installation chamber 501 is created within the cavity of the housing 50. The centrifugal component 71 of the centrifugal drainage mechanism 70 is placed inside the installation chamber 501. The partition baffle and the sealing baffle 60 serve to secondary block impurities and debris from entering the installation chamber 501 with the washing water.

[0139] In this embodiment, the encapsulation baffle 60 and the partition baffle can be closed plate-shaped structures, so that the mounting chamber 501 is a sealed chamber, and the water in the inner cylinder 40 will not enter the mounting chamber 501, thereby preventing wire debris and impurities from entering the mounting chamber 501.

[0140] Alternatively, in another embodiment, the encapsulation baffle 60 and the partition baffle can also be plate-shaped structures with multiple filter holes. The encapsulation baffle 60 and the partition baffle serve to filter the lint in the washing water in a secondary manner. The water in the inner cylinder 40 can enter the installation chamber 501 through the filter holes, but the lint will be blocked outside and will not enter the installation chamber 501.

[0141] Preferably, in this embodiment, the encapsulation baffle 60 and the partition baffle are closed plate-shaped structures, which can not only prevent wire debris from entering the installation chamber 501, but also effectively prevent washing water from entering the installation chamber 501, thereby further ensuring the reliability of the centrifugal drainage mechanism 70.

[0142] Furthermore, the housing 50 includes a top wall 51 and a side wall 52 connecting the top wall 51 and the inner wall of the washing machine inner drum 40. The distance between the encapsulation baffle 60 and the top wall 51 of the housing 50 is less than the distance between the top wall 51 of the housing 50 and the inner wall of the inner drum 40.

[0143] There is a gap between the bottom wall of the encapsulation baffle 60 and the inner wall of the inner cylinder 40. The gap between the lower wall of the encapsulation baffle 60 and the inner wall of the inner cylinder 40 forms a drain cavity 503 for discharging washing water. The drain cavity 503 is connected to the inside of the inner cylinder 40 and the drain outlet 401 on the inner cylinder 40. The washing water in the inner cylinder 40 can enter the drain outlet 401 on the inner cylinder 40 through the drain cavity 503 and then be discharged from the drain outlet 401.

[0144] like Figure 4 , Figure 5 , Figure 8 As shown, the partition baffle includes a first baffle 611 and a second baffle 612 disposed opposite to each other at the front and rear ends of the housing 50 along the length direction of the housing 50. The first baffle 611 and the second baffle 612 are respectively connected to the top wall 51 and the side wall 52 of the housing 50. The first baffle 611 and the second baffle 612 are integrally injection molded with the housing 50.

[0145] The relative distance between the first baffle 611 and the second baffle 612 is less than the length of the housing 50, and along the length direction of the housing 50, the length of the mounting chamber 501 is less than the length of the housing 50.

[0146] Preferably, the installation chamber 501 is located near one end of the housing 50, which provides more installation space for installing filter components inside the housing 50 compared to a location in the middle of the housing 50.

[0147] Furthermore, such as Figures 4 to 7 As shown, the sidewall 52 includes a first sidewall and a second sidewall connected to the two long strips of the top wall 51. The lower edges of the first sidewall and the second sidewall are provided with at least a portion corresponding to the notch to form a water inlet 521 for water intake. The water inlet 521 connects the drain outlet 401 on the inner cylinder 40 and the internal cavity of the inner cylinder 40.

[0148] The first and second sidewalls have corresponding notches along their lower edges. The notches have a certain axial extension length and are elongated. The encapsulation baffle 60 is embedded in the notches of the first and second sidewalls.

[0149] The upper edges of the first baffle 611 and the second baffle 612 are connected to the top wall 51 of the housing 50, and the two side edges are connected to the first side wall and the second side wall of the housing 50, respectively.

[0150] Preferably, a third baffle 613 is also provided inside the housing 50. The first baffle 611 and the third baffle 613 are located near the two ends of the housing 50. The first baffle 611 and the second baffle 612 divide the cavity of the housing 50 into three spaces. The spaces located on the two outer sides of the first baffle 611 and the second baffle 612 are installation spaces for independently installing the housing 50.

[0151] The lower edges of the first and second sidewalls of the housing 50 between the first baffle 611 and the third baffle 613 are notched. The encapsulation baffle 60 is installed within the mounting position formed by the first baffle 611, the second baffle 612, the first sidewall, and the second sidewall. The second baffle 612 is disposed within the housing 50 between the first baffle 611 and the third baffle 613, and the lower edge of the second baffle 612 extends to the upper wall surface of the encapsulation baffle 60. Taking the installation chamber 501 disposed within the housing 50 near the opening end of the inner cylinder 40 as an example, the first baffle 611 is disposed near the opening side, and the installation chamber 501 is formed between the second baffle 612, the first baffle 611, and the inner wall surface of the encapsulation baffle 60.

[0152] In one implementation, such as Figures 6 to 8 As shown, the garment lifting device 5 provided in this embodiment has irregularly shaped grid baffles 603 at the positions corresponding to the water inlet 521 on both sides below the encapsulation baffle 60, which allows the washing water to flow through at a certain bending angle. When the washing water flows through the water inlet 521, the lint will be blocked and attached to the irregularly shaped grid baffles 603, and will not enter the drain cavity 503.

[0153] Preferably, the irregular grid baffle 603 is arranged in multiple ways along the two long strips of the encapsulation baffle 60. By arranging multiple irregular grid baffle 603s at intervals along the two long strips of the encapsulation baffle 60, it is possible to effectively prevent wire debris from entering the drainage chamber 503 and blocking the drainage outlet 401. This avoids the phenomenon of wire debris adhering to the centrifugal drainage mechanism 70 or blocking the drainage outlet 401, thus affecting normal drainage.

[0154] Furthermore, the irregular grid baffle 603 is an arc-shaped grid baffle with an arc-shaped bend, for example, the irregular grid baffle 603 can be a forward "S" or a reverse "S" shape; or, the irregular grid baffle 603 is a folded grid baffle with a straight bend, for example, the irregular grid baffle 603 can be a "<" or ">" shape; when the washing water flows through the irregular grid baffle 603, the lint will be blocked at the arc-shaped bend or straight bend of the irregular grid baffle 603 and will not enter the drain cavity 503.

[0155] Furthermore, the gap between two adjacent irregular grid baffles 603 forms a flow guiding channel. The set bending angle makes the flow guiding channel form an arc-shaped reversing flow guiding channel from the inlet to the outlet. On the one hand, it plays the role of blocking filter wire debris, and on the other hand, it plays the role of reversing the flow direction and increasing the flow velocity of water.

[0156] Preferably, the outlet end of the irregular grid baffle 603 is bent or folded toward the drain outlet 401 to guide the drainage water to converge toward the drain outlet 401.

[0157] For example, if the irregular grid baffle 603 is an arc-shaped grid baffle in the shape of a forward "S" or a reverse "S", then the arc-shaped grid baffle located on the lower left side of the drain outlet 401 is in the shape of a forward "S", the arc-shaped grid baffle located on the lower right side of the drain outlet 401 is in the shape of a reverse "S", the arc-shaped grid baffle located on the upper left side of the drain outlet 401 is in the shape of a reverse "S", and the arc-shaped grid baffle located on the upper right side of the drain outlet 401 is in the shape of a forward "S".

[0158] For example, if the irregular grid baffle 603 is a folded grid baffle in the shape of "<" or ">", then the folded grid baffle located on the lower left side of the drain outlet 401 is in the shape of a forward "<", the arc-shaped grid baffle located on the lower right side of the drain outlet 401 is in the shape of ">", the arc-shaped grid baffle located on the upper left side of the drain outlet 401 is in the shape of a reverse "<", and the arc-shaped grid baffle located on the upper right side of the drain outlet 401 is in the shape of a forward ">".

[0159] Through the above design, the gap space between the two irregular grid baffles 603 forms a flow channel with the outlet end facing the drain 401, which facilitates the collection of water flow.

[0160] Preferably, the arc-shaped grid ribs / folded grid ribs each have multiple arc-shaped bends / straight bends. By setting multiple bends or bends, the water flow bends multiple times, resulting in a better effect of blocking wire debris.

[0161] Alternatively, the arc-shaped grid ribs / folded grid ribs are multi-layered structures with staggered upper and lower layers. By setting multiple layers of arc-shaped grid ribs / folded grid ribs, the water flow can bend multiple times, and the effect of blocking wire debris is better.

[0162] Furthermore, in the above scheme, the arc-shaped grid ribs / folded grid ribs are arranged in a staggered manner between the upper and lower layers. The upper arc-shaped grid ribs / folded grid ribs are located between the two grid ribs of the lower layer. If the wire debris passes through the guide channel between the two grid ribs of the lower layer, the grid ribs of the upper layer can play a secondary role in blocking the wire debris from passing through, further preventing the wire debris from entering the drainage cavity 503 of the housing 50.

[0163] In another embodiment, the irregular grid baffle 603 includes longitudinal ribs and multiple guide ribs arranged on both sides of the longitudinal ribs. The guide ribs on two adjacent longitudinal ribs are staggered and interwoven. The multiple guide ribs arranged on both sides of the longitudinal ribs form a curved guide channel, which effectively blocks the wire debris.

[0164] The guide rib can be a horizontally arranged transverse rib. Preferably, the guide rib is inclined, and the guide rib is inclined in the direction of the flow channel outlet, so as to guide the water flow.

[0165] More preferably, the guide ribs located at the outlet end of the flow channel are inclined toward the drain outlet 401 of the inner cylinder 40, so that the water flow can be collected and discharged at the drain outlet 401.

[0166] The washing machine clothes lifting device 5 provided in this embodiment, through the irregular grid baffle 603 set in the water inlet 521 of the housing 50, which allows the washing drain water to flow through at a certain bend angle, can effectively prevent lint from entering the drain chamber 503 and blocking the drain outlet 401, thus avoiding the phenomenon of lint adhering to the centrifugal drainage mechanism 70 or blocking the drain outlet 401, which would affect normal drainage.

[0167] Furthermore, the first gap space formed between the encapsulation baffle 60, the partition baffle, and the inner wall of the housing 50 is the mounting chamber 501. A second gap space is formed between the outer wall of the partition, the inner wall of the housing 50, and the inner wall of the inner cylinder 40 located around the drain outlet 401. The second gap space communicates with the inside of the inner cylinder 40 and the drain outlet 401 opened on the inner cylinder 40, respectively. Water in the inner cylinder 40 flows through the second gap space and is discharged from the drain outlet 401.

[0168] Preferably, the second space includes a drainage cavity 503 located below the encapsulation baffle 60, the mounting chamber 501 is located near the end of the housing 50, and the second space also includes a filter cavity 502 formed by the outer side of the first baffle 611 / second baffle 612 and the inner wall of the housing 50, and a filter structure is installed in the filter cavity 502.

[0169] Specifically, the filtration structure within the filter chamber 502 includes various filtration structures such as a filter screen and a comb-shaped filter structure 5021. The top wall of the housing 50 has through holes, and the comb-shaped filter structure 5021 includes multiple rows of comb-shaped protrusions. Each row of comb-shaped protrusions forms a plane parallel to the top wall 51 of the housing 50 with the through holes, intercepting impurities. The cross-sections of these filtration structures are used as filtration sections to intercept impurities such as lint.

[0170] like Figure 3 , Figure 4 as well as Figure 8 As shown, in this embodiment, the filter chamber 502 is formed by the space between the right side of the second baffle 612 and the inner wall of the housing 50. Multiple through holes are provided on the top wall 51 or side wall 52 of the housing 50 corresponding to the filter chamber 502, and these through holes communicate with the filter chamber 502. Preferably, the through holes are located on the top wall 51 of the housing 50. The filter chamber 502 exchanges water flow with the water in the inner cylinder 40 through the through holes on the housing 50, and the drain chamber 503 guides the water in the inner cylinder 40 to the drain outlet 401 on the inner cylinder 40. At least one opening 5022 needs to be provided in the filter chamber 502 so that the drained water can flow into the drain outlet 401 through the opening 5022.

[0171] Since the drainage water in the filter chamber 502 ultimately needs to flow to the drain outlet 401 for discharge, a guide plate 5023 can be installed in the filter chamber 502 to guide the water flow to the drain outlet 401. The guide plate 5023 makes it easier for the water flow in the filter chamber 502 to converge at the drain outlet 401, resulting in a larger flow of water towards the drain outlet 401. Even after cleaning the filter structure, water containing debris such as lint can flow to the drain outlet 401 and be discharged under the guidance of the guide plate 5023. Because the water flow after cleaning the filter structure contains debris such as lint that obstructs the water flow, the guide plate 5023 further concentrates the water flow, resulting in a larger flow of water towards the drain outlet 401, making it easier for debris to be discharged from the drain outlet 401.

[0172] Specifically, such as Figures 4 to 6The guide plate 5023 is an inclined structure that gradually slopes from the third baffle 613 towards the opening 5022 below the second baffle 612. This facilitates the flow of drainage water along the inclined guide plate 5023 towards the drain outlet 401. Furthermore, the inclined structure of the guide plate 5023 increases the flow velocity of the drainage water, making it easier to flush away debris such as lint from the drainage water. Preferably, all guide plates 5023 form a conical surface with the tip pointing towards the drain outlet 401. The conical surface formed by the inclined guide plates 5023 gradually reduces the cross-sectional area at the drain outlet 401, accelerating the flow velocity of the water towards the drain outlet 401 and further facilitating the discharge of water containing lint from the drain outlet 401.

[0173] Furthermore, such as Figures 4 to 8 As shown, the centrifugal drainage mechanism 70 also includes a valve plug component 72. The valve plug component 72 includes a valve plug column 721 coaxially arranged with the drain port 401 and a valve plug 722 connected to the lower end of the valve plug column 721. In its natural state, the valve plug 722 seals the drain port 401 to ensure the sealing of the inner cylinder 40. The sealing baffle 60 has a valve plug through hole at the position corresponding to the drain port 401, through which the valve plug column 721 can pass.

[0174] The counterweight 711 and connecting rod 712 of the centrifugal component 71, as well as the hinge point of the connecting rod 712 and valve plug 721, are all provided in the installation chamber 501, which effectively prevents lint from getting tangled and attached to the counterweight 711 or the hinge point of the connecting rod 712 and valve plug 721, thus affecting the normal operation of the centrifugal drainage mechanism 70.

[0175] Preferably, a sleeve-shaped mounting base 723 is installed on the upper side of the encapsulation baffle 60. The inner through hole of the mounting base 723 is coaxially arranged with the valve plug through hole on the encapsulation baffle 60. The valve plug 721 is movably disposed within the mounting base 723. A water-sealing structure is provided on the valve plug 721 and / or the mounting base 723. The water-sealing structure further prevents wire debris from entering the mounting chamber 501 with the washing water, ensuring that the centrifugal drainage mechanism 70 is in a debris-free environment and reducing the possibility of wire debris adhesion and entanglement.

[0176] like Figure 4 and Figure 5As shown, a pivot hole or pivot is provided in the middle of the connecting rod 712. A pivot bracket 724 extends from the mounting base 723 near the counterweight 711. The pivot bracket 724 is rotatably supported by the pivot hole of the connecting rod 712. When the counterweight 711 rotates up and down around the pivot bracket 724 and the pivot point of the connecting rod 712 under the action of centrifugal force, it drives the valve plug 722 to move up and down in the second interval space between the lower side wall of the encapsulation baffle 60 and the inner wall of the inner cylinder 40, thereby opening or closing the drain port 401.

[0177] Furthermore, such as Figures 6 to 8 As shown, the encapsulation baffle 60 is injection molded with a first bolt post, and the inner wall of the housing 50 is injection molded with a second bolt post 53. The encapsulation baffle 60 is threadedly connected to the second bolt post 53 by bolts 605 passing through the first bolt post, and the encapsulation baffle 60 is fastened to the lower opening of the partition baffle 56.

[0178] Preferably, such as Figure 4 , Figure 5 As shown, the encapsulation baffle 60 is provided with a first flange 601 and a second flange 602 that respectively abut and limit the engagement of the first baffle 611 and the second baffle 612. The first flange 601 is formed by extending downward from the side edge of the encapsulation baffle 60 near the first baffle 611. The outer wall surface of the first flange 601 is in close contact with the inner wall surface of the first baffle 611. The second flange 602 is provided on the encapsulation baffle 60 at a position corresponding to the second baffle 612, extending upward. The second flange 602 covers the lower edge of the second baffle 612, and the outer wall surface of the second baffle 612 is in close contact with the inner wall surface of the second flange 602.

[0179] The structure of the first flange 601 and the second flange 602 ensures that the encapsulation baffle 60 fits tightly with the first baffle 611 and the second baffle 612. The face-to-face contact ensures a sealing effect at the junction, preventing lint from entering the installation chamber 501 from the connection between the first baffle 611, the second baffle 612 and the encapsulation baffle 60 with the washing water. At the same time, it limits the displacement between the encapsulation baffle 60 and the housing 50 in the extension length direction of the clothing lifting device 5, further ensuring the stability between the encapsulation baffle 60 and the housing 50.

[0180] In this embodiment, the encapsulation baffle 60 is fastened to the lower end of the housing 50 by bolts 605, thus limiting the position of the encapsulation baffle 60 in the vertical direction. The position of the encapsulation baffle 60 in the front-back direction is limited by the cooperation of the first flange 601 with the first baffle 611 and the second flange 602 with the second baffle 612.
