The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0055] The present invention will be further described in detail below with reference to the embodiments.

The boss structure 643 is an internally hollow circular truncated cone boss structure 643 formed by downward recessing the extension mounting plate 642. The fastening protrusion is fixedly arranged on the lower surface of the circular truncated cone boss structure 643. The boss structure 643 enhances the strength and stability of the limiting protrusion structure on the one hand, and forms a stepped limiting step between the boss structure 643 and the limiting protrusion on the other hand. When the limiting protrusion is inserted and matched with the positioning hole 402, the limiting boss can also play a certain limiting role.

[0090] Example Two

[0091] As shown in Figures 1-7 , the embodiment provides a clothes lifting device 5 for a washing machine on the basis of the first embodiment, mainly to solve the problem that the position of the centrifugal component 71 of the centrifugal drainage mechanism 70 in the clothes lifting device 5 is easy to deviate due to high-speed rotation and vibration of the washing machine, which affects normal drainage, and the lifting device made of plastic material is deformed, and the appearance does not match well.

[0092] Specifically, as shown in Figures 3-5 , the clothes lifting device 5 comprises a shell 50 having an open cavity at one end, and a packaging baffle 60 which is blocked at the open end of the shell 50 to form an installation chamber 501 in the clothes lifting device 5 for installation of the centrifugal drainage mechanism 70, a lint filter and the like.

[0093] The clothes lifting device 5 further comprises a centrifugal drainage mechanism 70 which is installed in the receiving chamber of the shell 50 and can be opened for drainage under the action of centrifugal force. Preferably, in the embodiment, the centrifugal drainage mechanism 70 is fixedly installed on the packaging baffle 60.

[0094] The centrifugal drainage mechanism 70 comprises a centrifugal component 71 and a valve plug component 72, the centrifugal component 71 generates centrifugal motion on the first motion surface under the action of centrifugal force, driving the valve plug component 72 to open the drain port 401 on the inner drum 40 of the washing machine, and to drain water.

[0095] The laundry lifting device 5 provided in the embodiment further comprises a limiting structure 62 fixedly arranged on the packaging baffle 60, the limiting structure 62 limits the eccentric component 71 from generating eccentric motion deviating from the first motion surface.

[0096] The limiting structure 62 arranged on the packaging baffle 60 limits the eccentric component 71 from generating eccentric motion deviating from the first motion surface, which can effectively prevent the position of the counterweight block 711 of the eccentric component 71 from being deviated and other problems during high-speed rotation of the washing machine, and affect normal drainage of the centrifugal drainage mechanism 70.

[0097] Further, the eccentric component 71 comprises a counterweight block 711 generating centrifugal motion along the first motion surface under the action of centrifugal force, due to high-speed rotation and vibration of the washing machine, the position of the counterweight block 711 in the laundry lifting device 5 is prone to be deviated and other problems, affecting normal drainage, and long-term deviation of the counterweight block 711 also easily causes deformation of the lifting rib made of plastic material, and causes appearance mismatching and other problems.

[0098] In the embodiment, the limiting structure 62 comprises limiting baffles arranged on left and right sides of the counterweight block 711, the position of the counterweight block 711 is limited by the limiting baffles arranged on both sides of the counterweight block 711, which can effectively prevent the counterweight block 711 from being deviated to left and right sides under the action of external force.

[0099] Further, as shown in Figure 4 and Figure 5 The limiting baffles comprise a first limiting plate 621 and a second limiting plate 622 fixedly arranged on the packaging baffle 60 at intervals, and a limiting space for limiting installation of the counterweight block 711 is formed between the first limiting plate 621 and the second limiting plate 622.

[0100] Further, the counterweight 711 comprises a first side wall and a second side wall oppositely arranged on the left and right sides of the counterweight 711, wherein the first limiting plate 621 is located outside the first side wall and parallel to the first side wall of the counterweight 711. The second limiting plate 622 is located outside the second side wall and parallel to the second side wall of the counterweight 711. The first limiting plate 621 and the first side wall have a certain gap distance, and the second limiting plate 622 and the second side wall have a certain gap distance, so as to avoid affecting the normal centrifugal motion of the counterweight 711 on the first motion plane.

[0101] Preferably, the first motion plane is parallel to the radial direction of the drum of the washing machine, and the extension direction of the limiting baffle is parallel to the first motion plane and limits the left and right deviation of the counterweight 711 relative to the first motion plane. The first limiting plate 621 and the second limiting plate 622 limit the motion of the counterweight 711 on the deviation plane perpendicular to the first motion plane.

[0102] Preferably, the first limiting plate 621 and the second limiting plate 622 are integrally injection molded with the packaging baffle 60. In the embodiment of the present application, the first limiting plate 621 and the second limiting plate 622 are integrally injection molded with the packaging baffle 60, which is simple in forming process and low in manufacturing cost.

[0103] In the embodiment, the first limiting plate 621 and the second limiting plate 622 are integrally formed on the packaging baffle 60, which is easier to form and more convenient to process than being arranged in the shell 50.

[0104] Further, the laundry lifting device 5 provided in the embodiment further comprises a reinforcing structure for increasing the strength of the limiting baffle.

[0105] Preferably, the reinforcing structure is a reinforcing rib 623 connected between the limiting baffle and the packaging baffle 60, and the reinforcing rib 623 is a plurality of reinforcing ribs arranged at intervals along the length direction of the limiting baffle. The reinforcing rib 623 comprises a first connecting edge and a second connecting edge connected perpendicularly, the first connecting edge is connected and fixed with the limiting baffle, and the second connecting edge is connected and fixed with the packaging baffle 60.

[0106] More preferably, the reinforcing rib 623 is integrally injection molded between the packaging baffle 60 and the limiting baffle.

[0107] Further, the laundry lifting device 5 further comprises a positioning structure for limiting the deviation of the position of the packaging baffle 60.

[0108] The embodiment further sets the positioning structure in the clothes lifting device 5 to limit the offset of the packaging baffle 60, which plays a double protection role. The position of the packaging cover plate in the shell 50 is prevented from being offset, and the stability of the positions of the first limiting plate 621 and the second limiting plate 622 is effectively ensured, further avoiding the phenomenon that the position of the counterweight 711 is skewed.

[0109] Further, the positioning structure includes the first clamping wall 631 and the second clamping wall 632 fixedly arranged on both sides of the packaging baffle 60, and the first clamping wall 631 and the second clamping wall 632 are arranged along the length direction of the packaging baffle 60.

[0110] As shown in Figures 4-7 , along the length direction of the packaging baffle 60, the packaging baffle 60 includes the oppositely arranged first long edge and the second long edge, the first clamping wall 631 is arranged on the upper side of the packaging baffle 60 close to the first long edge, and the second clamping wall 632 is arranged on the upper side of the packaging baffle 60 close to the second long edge.

[0111] The first clamping wall 631 and the second clamping wall 632 can be long strip-shaped clamping walls arranged along the length direction of the packaging baffle 60, or can be clamping walls arranged on the packaging baffle 60 at intervals.

[0112] Further, the positioning structure further includes the first resisting wall 541 and the second resisting wall 542 fixedly arranged on both sides of the shell 50, the first clamping wall 631 is limitingly clamped in the first resisting wall 541, and the second clamping wall 632 is limitingly clamped in the second resisting wall 542.

[0113] Preferably, the first clamping wall 631 and the second clamping wall 632 are arranged on the packaging baffle 60 close to the two side edges, and the first resisting wall 541 and the second resisting wall 542 are formed by the side walls on both sides of the shell 50.

[0114] Specifically, as shown in Figure 2 and Figure 4 , the shell 50 includes the strip-shaped top wall 51 and the side wall 52 connected on both sides of the strip-shaped top wall 51, and the first resisting wall 541 and the second resisting wall 542 are formed by the lower edges of the side walls 52 on both sides of the shell 50 extending vertically downward. The first clamping wall 631 and the second clamping wall 632 are respectively clamped and limited in the side walls 52 on both sides of the shell 50.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] like Figure 4 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.

[0121] 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.

[0122] 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.

[0123] As Figure 5 shown in the embodiment, a plurality of connecting ribs 635 are connected between the first clamping wall 631 and the third clamping wall 633, and between the second clamping wall 632 and the fourth clamping wall 634. The connecting ribs 635 are arranged along the length direction of the packaging baffle 60 between the first clamping wall 631 and the third clamping wall 633, and between the second clamping wall 632 and the fourth clamping wall 634. The connecting ribs 635 further enhance the stability of the structure between the first clamping wall 631 and the third clamping wall 633, and between the second clamping wall 632 and the fourth clamping wall 634, so as to avoid the phenomenon of shaking and deformation when the blocking wall of the shell 50 is matched.

[0124] Further, the connecting ribs 635 are L-shaped connecting plates between the first clamping wall 631 and the third clamping wall 633, and between the second clamping wall 632 and the fourth clamping wall 634. By setting the connecting ribs 635 as L-shaped, on the one hand, the stability of the connection can be ensured, and on the other hand, the material cost can be reduced.

[0125] In another embodiment, a plurality of water drainage holes are arranged on the packaging baffle 60 between the first clamping wall 631 and the third clamping wall 633, and between the second clamping wall 632 and the fourth clamping wall 634. The water drainage holes can prevent a large amount of residual water from being stored in the groove formed by the first clamping wall 631, the third clamping wall 633 and the packaging baffle 60 therebetween, or in the groove formed by the second clamping wall 632, the fourth clamping wall 634 and the packaging baffle 60 therebetween, and cannot be drained, which can breed bacteria and affect the cleaning effect inside the washing machine.

[0126] Preferably, at least one water drainage hole is arranged on the packaging baffle 60 between every two connecting ribs 635, so as to ensure that the washing water in the space between every two connecting ribs 635 can be drained, and to ensure that the washing water cannot be stored in any corner position in the packaging baffle 60.

[0127] Example Three

[0128] The embodiment provides a laundry lifting device 5 for a washing machine on the basis of the first embodiment or the second embodiment, and mainly aims to solve the problem that the counterweight of the centrifugal drainage mechanism arranged in the shell is easy to impact other components and generate noise when doing centrifugal motion.

[0129] As Figures 1-7 shown in the embodiment, the embodiment provides a laundry lifting device 5 for a washing machine, which comprises:

[0130] a shell 50 having an open cavity at one end;

[0131] The centrifugal drainage mechanism 70 is arranged in the shell 50 and comprises a centrifugal component 71 and a valve plug component 72 connected with the centrifugal component 71.

[0132] The centrifugal component 71 comprises a counterweight 711 capable of generating centrifugal motion under the action of centrifugal force, and the counterweight 711 drives the valve plug component 72 to act.

[0133] The shell 50 has a mounting cavity 501 in the cavity for mounting the centrifugal drainage mechanism 70, and the mounting cavity 501 and / or the counterweight 711 is provided with a buffer structure.

[0134] The laundry lifting device 5 for the washing machine provided by the present application effectively avoids the noise caused by the counterweight 711 impacting the inner drum 40 or the side wall of the mounting cavity 501 due to the centrifugal motion of the counterweight 711, and the phenomenon of affecting the user experience, and the buffer structure also protects the counterweight 711 and prolongs the service life of the centrifugal drainage mechanism 70.

[0135] Further, the shell 50 is provided with an encapsulation baffle 60 near the open end, and the encapsulation baffle 60 divides the mounting cavity 501 for mounting the centrifugal component 71 above the cavity of the shell 50.

[0136] As shown in the drawings, Figures 1-5 The centrifugal drainage mechanism 70 provided by the present embodiment comprises a centrifugal component 71 and a valve plug component 72, the centrifugal component 71 comprises a counterweight 711 and a connecting rod 712, and the counterweight 711 comprises a counterweight shell and a counterweight 711 arranged in the counterweight shell.

[0137] The counterweight shell is arranged outside the counterweight 711 and covers the counterweight 711, effectively avoiding direct contact between the counterweight 711 and the washing water, which is prone to rust and corrosion and affects the normal work of the centrifugal drainage mechanism 70. The counterweight shell also has a protective effect and avoids damage to the counterweight 711 during centrifugal motion.

[0138] As shown in the drawings, Figure 2 , Figure 3 and Figure 5As shown, one end of the connecting rod 712 of the centrifugal drainage mechanism 70 is rotatably connected with the counterweight block shell 711, and the other end is rotatably connected with 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 with the counterweight block shell outside the counterweight block 711, which is easier to process and form compared with being directly connected and fixed with the counterweight block 711. The counterweight block 711 generates centrifugal motion under the action of centrifugal force, driving the valve plug component 72 to act to open the drainage port 401 on the inner cylinder 40 for drainage.

[0139] As shown in the drawings, Figures 2-7 The centrifugal component 71 is arranged in the installation chamber 501 above the packaging baffle 60. The buffer structure includes a first embossed structure 604 arranged on the packaging baffle 60 and outwardly recessed at a position corresponding to the counterweight block 711. The first embossed structure 604 arranged on the packaging baffle 60 provides a larger buffer space for the downward movement of the counterweight block 711, avoiding the phenomenon of impacting the packaging baffle 60 and generating a larger noise due to the limited activity space of the counterweight block 711.

[0140] Further, the first embossed structure 604 includes an embossed peripheral wall protruding from the lower surface of the packaging baffle 60 and an embossed bottom wall 6044. The shape and size of the embossed bottom wall 6044 are adapted to the cross-sectional shape and size of the counterweight block 711. The first embossed structure 604 provides sufficient buffer space for the entire counterweight block 711, protecting the counterweight block 711 while avoiding the phenomenon of impacting the packaging baffle 60 and generating noise.

[0141] Further, the centrifugal drainage mechanism 70 further includes a valve plug component 72 connected with the counterweight block 711 through a lever structure. The counterweight block 711 generates centrifugal motion under the action of centrifugal force, driving the valve plug component 72 to act to open the drainage port 401 on the inner cylinder 40 for drainage.

[0142] As shown in the drawings, Figure 2 and Figure 6 The first embossed structure 604 is arranged to extend close to the side of the valve plug component 72 and is provided with a buffer taper angle 6043 for avoiding the lever structure. The cross section of the first embossed structure 604 is similar to the shape of a pencil tip. The first embossed structure 604 is provided with a top corner structure gradually inclined and extending to the side of the valve plug component 72 at a position corresponding to the lever structure, forming the buffer taper angle 6043. The buffer taper angle 6043 can avoid the lever structure, providing the first embossed structure 604 with a larger buffer space for the counterweight block 711.

[0143] Further, as shown in the drawings, Figure 2 , Figure 6As shown, the buffer structure further comprises a chamfer structure arranged on the side of the counterweight 711 away from the valve plug component 72. The chamfer structure is formed by the missing corner of the end of the counterweight 711 away from the valve plug component 72. The falling of the counterweight 711 can be provided with more buffer space, so as to ensure that the centrifugal drainage mechanism 70 has sufficient space to open or close the drainage port 401.

[0144] Preferably, in the embodiment, as shown in Figure 2 、 Figure 3 、 Figure 5 As shown, the counterweight 711 is in the shape of a quadrangular prism. The buffer missing corner is a chamfer structure arranged below the end of the counterweight 711 away from the valve plug component 72. The chamfer structure has an inclined wall surface extending from the bottom wall of the counterweight 711 to the left end wall of the counterweight 711.

[0145] Further, as shown in Figure 2 、 Figure 6 The buffer structure further comprises a first buffer pad 713 arranged 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 meets the design requirements of the buffer protection of the counterweight 711.

[0146] The first buffer pad 713 can be wrapped outside the entire bottom wall of the counterweight 711. The first buffer pad 713 can be fixed on the counterweight 711 by bonding or clamping.

[0147] Preferably, the bottom wall of the counterweight 711 comprises a flat wall surface and an inclined wall surface formed by the chamfer structure. In order to save materials, the first buffer pad 713 is arranged between the flat wall surface and the inclined wall surface.

[0148] Because the junction position of the flat wall surface and the inclined wall surface of the counterweight 711 will first contact the packaging baffle 60 when falling, the above design wraps the junction position of the flat wall surface and the inclined wall surface in the first buffer pad 713, which effectively plays a buffer and shock absorption protection role while minimizing the use of materials.

[0149] Alternatively, in another scheme, the first buffer pad 713 is arranged outside the inclined wall surface of the chamfer structure, and the first buffer pad 713 has a certain elastic thickness.

[0150] Further, as shown in Figure 2 、 Figure 6As shown, the buffer structure further comprises a second buffer pad 6041 arranged on the profiled bottom wall 6044 of the first profiled structure 604, and the second buffer pad 6041 is arranged on the profiled bottom wall 6044, so that when the counterweight 711 falls, the first buffer pad 713 and the second buffer pad 6041, and the first profiled structure 604 all play an effective buffering and damping role, achieving the purpose of damping and noise reduction for the counterweight 711 from multiple perspectives.

[0151] Preferably, the profiled bottom wall 6044 is provided with a buffer pad mounting position corresponding to the intersection position of the chamfer structure of the counterweight 711 and the bottom wall of the counterweight 711, and the second buffer pad 6041 is embedded and mounted in the buffer pad mounting position. The upper surface of the second buffer pad 6041 is slightly higher than the upper surface of the profiled bottom wall 6044, or is flushly arranged.

[0152] The buffer pad mounting position can be a mounting hole arranged through the profiled bottom wall 6044, or a blind hole. The second annular pad 6041 is embedded and pressed in the buffer pad mounting position. The second buffer pad does not occupy the falling space of the counterweight 711. When the space of the first profiled structure 604 cannot provide sufficient buffer space for the counterweight 711, the second buffer pad 6041 provides more buffer space for the counterweight 711. Even if the counterweight 711 hits the second buffer pad 6041, it will not produce a large noise, further improving the buffering and noise reduction effect of the buffer structure.

[0153] Further, as shown in the drawings, Figures 2-7 The profiled bottom wall 6044 of the first profiled structure 604 is provided with one or more spaced drain holes 6042. If the installation chamber 501 of the shell 50 accumulates washing water, the water can be drained through the drain holes 6042 in time. Since the profiled bottom wall 6044 of the first profiled structure 604 is the lowest position of the entire installation chamber 501, it is more conducive to water flow collection and discharge to arrange the drain holes 6042 on the profiled bottom wall 6044 of the first profiled structure 604.

[0154] Preferably, a one-way valve is arranged in the drain hole 6042. The one-way valve allows water in the installation chamber 501 to be drained through the drain hole 6042, but water in the inner cylinder 40 cannot enter the installation chamber 501 through the drain hole 6042, further ensuring the sealing effect of the installation chamber 501.

[0155] Further, in another extended solution, the top wall 51 of the shell 50 is provided with a second embossed structure protruding upward corresponding to the position of the counterweight 711, and the buffer structure further comprises a second embossed structure providing a buffer space for the rising of the counterweight 711. By providing the second embossed structure, the phenomenon that the counterweight 711 collides with the top wall 51 of the shell 50 to generate a larger noise when doing centrifugal motion can be effectively avoided.

[0156] Moreover, by providing the second embossed structure, the initial position of the counterweight 711 can be correspondingly raised, which also means that a larger buffer space is provided for the falling of the counterweight 711.

[0157] Example Four

[0158] The embodiment is based on the above-mentioned embodiment and provides an improved clothes lifting device for a washing machine, mainly to solve the problem that the components of the centrifugal drainage mechanism installed in the existing clothes lifting device are easy to attach and entangle lint, causing the centrifugal drainage mechanism to not close in place or not to drain normally.

[0159] As shown in Figures 1-6 , the embodiment provides a clothes lifting device 5 for a washing machine, and the cavity of the shell 50 is spaced apart from a separately closed installation chamber 501, and the centrifugal drainage mechanism 70 is at least partially installed in the installation chamber 501.

[0160] As shown in Figure 2 , Figure 6 Since the shell 50 is provided with a water inlet 521 for the washing water in the inner drum 40 to flow into the shell 50, the cavity of the shell 50 is in communication with the inside of the inner drum 40, and the centrifugal drainage mechanism 70 is directly installed in the cavity of the shell 50. During the washing process, lint inevitably enters the shell 50 along with the water flow, and then enters the centrifugal drainage mechanism 70.

[0161] In the embodiment, the centrifugal drainage mechanism 70 is installed in the separately closed installation chamber 501 additionally provided in the cavity of the shell 50, which can play a role in blocking the lint from entering the centrifugal drainage mechanism 70 twice. The lint in the inner drum 40 will not enter the installation chamber 501 along with the water flow, so that the centrifugal drainage mechanism 70 is in a lint-free environment, which fundamentally avoids the possibility of lint attachment and entanglement, and effectively ensures the reliability of the work of the centrifugal drainage mechanism 70.

[0162] Further, as shown in Figure 2 and Figure 6As shown, a partition baffle 56 is fixed in the middle of the shell 50, and a folding baffle 601 corresponding to the partition baffle 56 is arranged on the packaging baffle 60. Two chambers are separated in the shell 50, one is a mounting chamber 501 for mounting the centrifugal drainage mechanism 70 and the like, and the other is a filtering chamber 502 for mounting the lint filter and the like. The partition baffle 56, the folding baffle 601, the second limiting baffle 552, the second folding wall 645, the packaging baffle 60, and the shell 50 together form the mounting chamber 501 which is arranged in a relatively independent and closed manner. The partition baffle 56, the folding baffle 601, the first limiting baffle 551, the first folding wall 644, the packaging baffle 60, and the shell 50 together form the filtering chamber 502.

[0163] Since the mounting chamber 501 is arranged in an independent and closed manner, the centrifugal part 71 of the centrifugal drainage mechanism 70 is arranged in the mounting chamber 501, and the partition baffle 56 and the packaging baffle 60, the folding baffle 601, the second limiting baffle 552, and the second folding wall 645 can play a role of blocking the impurities and lint from entering the mounting chamber 501 along with the washing water.

[0164] In this embodiment, the packaging baffle 60, the folding baffle 601, the partition baffle 56, the second limiting baffle 552, and the second folding wall 645 can be closed plate structures, so that the mounting chamber 501 is a sealed chamber, and the water in the inner cylinder 40 cannot enter the mounting chamber 501, thereby avoiding the entry of the lint impurities into the mounting chamber 501.

[0165] Alternatively, in another scheme, the packaging baffle 60, the folding baffle 601, the partition baffle 56, the second limiting baffle 552, and the second folding wall 645 can also be plate structures with a plurality of filter holes. The packaging baffle 60 and the partition baffle 56 play a role of filtering the lint in the washing water twice, and the water in the inner cylinder 40 can enter the mounting chamber 501 through the filter holes, but the lint cannot enter the mounting chamber 501.

[0166] Preferably, the packaging baffle 60, the folding baffle 601, the partition baffle 56, the second limiting baffle 552, and the second folding wall 645 in this embodiment are closed plate structures, which can block the entry of the lint into the mounting chamber 501, and effectively block the entry of the washing water into the mounting chamber 501, further ensuring the reliability of the operation of the centrifugal drainage mechanism 70.

[0167] Further, the shell 50 comprises a top wall 51 and a side wall 52 connected between the top wall 51 and the inner wall of the inner drum 40, and the distance between the bottom wall of the packaging baffle 60 and the top wall 51 of the shell 50 is less than the distance between the top wall 51 of the shell 50 and the inner wall of the inner drum 40.

[0168] The gap space between the bottom wall of the packaging baffle 60 and the inner wall of the inner drum 40 forms a drainage cavity 503 between the lower wall surface of the packaging baffle 60 and the inner wall surface of the inner drum 40, the drainage cavity 503 is in communication with the inner chamber of the inner drum 40 and the drain port 401 on the inner drum 40 respectively, and the washing water in the inner chamber of the inner drum 40 can enter the drain port 401 on the inner drum 40 through the drainage cavity 503 and then be discharged from the drain port 401.

[0169] Further, as shown in Figures 2-7 , the side wall 52 comprises a first side wall and a second side wall connected to the two long edges of the top wall 51, and the lower edges of the first side wall and the second side wall are provided with notches to form water inlets 521 for water inlet.

[0170] The notches are provided on the lower edges of the first side wall and the second side wall correspondingly, and the notches have a certain axial extension length and are in the shape of a long strip. The packaging baffle 60 is embeddedly installed in the notches of the first side wall and the second side wall.

[0171] The shell 50 further comprises end side walls 53 connected to the front and rear ends of the top wall 51, and the upper edges of the first limiting ribs 551 and the second limiting ribs 552 are connected to the junction positions of the top wall 51 of the shell 50 and the shell 50, and the two side edges are connected to the first side wall and the second side wall of the shell 50 respectively.

[0172] In an embodiment, as shown in Figure 2 , Figure 6 The laundry lifting device 5 provided by the embodiment is provided with a special-shaped grid rib 603 allowing the washing drainage water to flow through with a certain bending angle below the two sides of the packaging baffle 60 and corresponding to the position of the water inlet 521, and the lint will be blocked and attached to the special-shaped grid rib 603 when the washing water flows through the water inlet 521, and will not enter the drainage cavity 503.

[0173] Preferably, as shown in Figure 7As shown, the special-shaped grid ribs 603 are arranged in multiple rows along the two long edges of the sealing baffle 60. The multiple special-shaped grid ribs 603 arranged in multiple rows along the two long edges of the sealing baffle 60 can effectively block the lint from entering the drainage cavity 503 and blocking the drainage port 401, thereby avoiding the phenomenon that the lint adheres to the centrifugal drainage mechanism 70 or blocks the drainage port 401, which affects the normal drainage.

[0174] Further, the special-shaped grid ribs 603 are arc-shaped grid ribs with arc-shaped bending corners, for example, the special-shaped grid ribs 603 can be in a forward "S" shape or a reverse "S" shape. Alternatively, the special-shaped grid ribs 603 are fold-shaped grid ribs with straight bending corners, for example, the special-shaped grid ribs 603 can be in a "<" shape or a ">" shape. When the washing water flows through the special-shaped grid ribs 603, the lint is blocked at the arc-shaped bending corners or the straight bending corners of the special-shaped grid ribs 603 and cannot enter the drainage cavity 503.

[0175] Further, the gap space between the adjacent two special-shaped grid ribs 603 forms a flow guide channel. The bending corners are arranged to form an arc-shaped reversing flow guide channel from the inlet to the outlet, which plays a role in blocking the lint and reverses the water flow to increase the water flow rate.

[0176] Preferably, the outlet end of the special-shaped grid rib 603 is bent or folded towards the drainage port 401 to guide the drainage water flow to converge towards the drainage port 401.

[0177] For example, the special-shaped grid rib 603 is an arc-shaped grid rib in a forward "S" shape or a reverse "S" shape. The arc-shaped grid rib located below the left side of the drainage port 401 is in a forward "S" shape, the arc-shaped grid rib located below the right side of the drainage port 401 is in a reverse "S" shape, the arc-shaped grid rib located above the left side of the drainage port 401 is in a reverse "S" shape, and the arc-shaped grid rib located above the right side of the drainage port 401 is in a forward "S" shape.

[0178] For another example, the special-shaped grid rib 603 is a fold-shaped grid rib in a "<" shape or a ">" shape. The fold-shaped grid rib located below the left side of the drainage port 401 is in a forward "<" shape, the arc-shaped grid rib located below the right side of the drainage port 401 is in a ">" shape, the arc-shaped grid rib located above the left side of the drainage port 401 is in a reverse "<" shape, and the arc-shaped grid rib located above the right side of the drainage port 401 is in a forward ">" shape.

[0179] Through the above design, the gap space between the two special-shaped grid ribs 603 forms a flow guide channel with the outlet end towards the direction of the drainage port 401, which facilitates the convergence of the water flow.

[0180] Preferably, the arc-shaped grid ribs / row-changing grid ribs have a plurality of arc-shaped turning angles / flat bending angles, respectively. By arranging a plurality of turning angles or bending angles, the water flow is bent multiple times, and the effect of blocking lint is better.

[0181] Alternatively, the arc-shaped grid ribs / row-changing grid ribs are arranged in a multi-layer structure with an upper layer and a lower layer being staggered. By arranging a plurality of arc-shaped grid ribs / row-changing grid ribs, the water flow is bent multiple times, and the effect of blocking lint is better.

[0182] In the above scheme, the arc-shaped grid ribs / row-changing grid ribs are arranged in a staggered manner between the upper layer and the lower layer, and the arc-shaped grid ribs / row-changing grid ribs in the upper layer are arranged between the two grid ribs in the lower layer. If the lint passes through the flow guide channel between the two grid ribs in the lower layer, the grid rib in the upper layer can block the lint from passing through again, further preventing the lint from entering the drain cavity 503 of the shell 50.

[0183] In another embodiment, the special-shaped grid ribs 603 include longitudinal ribs and a plurality of guide ribs arranged on both sides of the longitudinal ribs. The guide ribs on adjacent two longitudinal ribs are staggered and inserted. By arranging a plurality of guide ribs on both sides of the longitudinal ribs, a bent flow guide channel is formed, which effectively blocks the lint.

[0184] The guide rib can be a horizontal transverse rib. Preferably, the guide rib is arranged obliquely, and the guide rib is an inclined rib inclined toward the outlet of the flow guide channel, which guides the water flow.

[0185] More preferably, the guide rib at the outlet end of the flow guide channel is inclined toward the drain port 401 of the inner cylinder 40, which facilitates the water flow to the drain port 401.

[0186] The laundry lifting device 5 for the washing machine provided in the embodiment can effectively block the lint from entering the drain cavity 503 and blocking the drain port 401 by arranging the special-shaped grid ribs 603 at the water inlet 521 of the shell 50, which can make the washing and draining water flow at a certain bending angle, thereby avoiding the lint from adhering to the centrifugal drainage mechanism 70 or blocking the drain port 401, and preventing the normal drainage from being affected.

[0187] Further, the filter structure is installed in the filter cavity 502. The filter structure arranged in the filter cavity 502 includes a filter screen, a comb-shaped filter structure, and various structures that can filter. A through hole is formed in the top wall of the shell 50, and the comb-shaped filter structure includes a plurality of comb-shaped protrusions, each of which forms a plane for intercepting impurities parallel to the top wall 51 of the shell 50 where the through hole is arranged. The cross section of these filter structures is used as a filter section to intercept lint and other impurities.

[0188] As Figure 2 , Figure 4 , Figure 6 shown in the embodiment, a plurality of through holes are formed on the top wall 51 or the side wall 52 of the shell 50 corresponding to the filter cavity 502, and the through holes are in communication with the filter cavity 502. Preferably, the through holes are formed on the top wall 51 of the shell 50. The filter cavity 502 exchanges water flow with the inner cylinder 40 through the through holes formed on the shell 50, and the drain cavity 503 guides the water in the inner cylinder 40 to the drain port 401 formed on the inner cylinder 40. At least an opening 651 is required to be formed in the filter cavity 502 so that the drain water can flow into the drain port 401 through the opening 651.

[0189] Since the drain water in the filter cavity 502 ultimately needs to flow to the drain port 401 for drainage, a flow guide plate 652 can be arranged on the sealing baffle 60 to guide the water flow to the drain port 401. The arrangement of the flow guide plate 652 makes the water flow in the filter cavity 502 easily gather towards the drain port 401, so that the water flow to the drain port 401 is larger, that is, the water flow containing wire scraps and other impurities after cleaning the filter structure can flow to the drain port 401 under the guidance of the flow guide plate 652 and be drained. Since the water flow contains wire scraps and other impurities that hinder the flow of water after cleaning the filter structure, the arrangement of the flow guide plate 652 can make the water flow more concentrated, thereby making the water flow to the drain port 401 larger, so that the wire scraps and other impurities are more easily drained from the drain port 401.

[0190] Specifically as Figure 2 , Figure 5 shown, the flow guide plate 652 is an inclined structure that gradually inclines from the first folding wall 644 to the opening 651 below the folding baffle 601, which is more conducive to the drain water flowing along the inclined flow guide plate 652 to the drain port 401, and the inclined structure of the flow guide plate 652 can improve the flow rate of the drain water, which is more conducive to washing away the wire scraps and other impurities in the drain water. Preferably, all the flow guide plates 652 form a conical surface with the tip pointing to the drain port 401. The conical surface formed by the inclined flow guide plate 652 makes the cross-sectional area of the water flow to the drain port 401 gradually decrease, so that the flow rate of the water flow to the drain port 401 accelerates, which is more conducive to draining the water flow with wire scraps from the drain port 401.

[0191] Further, as Figures 2-7 shown, 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 the natural state, the valve plug 722 blocks the drain port 401 to ensure the sealing of the inner cylinder 40, and the sealing baffle 60 has a valve plug through hole corresponding to the position of the drain port 401, which can be passed through by the valve plug column 721.

[0192] The counterweight 711 and the connecting rod 712 of the centrifugal component 71 and the hinge point of the connecting rod 712 and the valve plug column 721 are provided in the installation chamber 501, effectively avoiding that the wire scraps are wound and attached at the hinge position of the counterweight 711 or the connecting rod 712 and the valve plug column 721, affecting the normal work of the centrifugal drainage mechanism 70.

[0193] Preferably, as shown in Figure 2 , Figure 5 , the mounting seat 723 is integrally formed on the packaging baffle 60, the inner through hole of the mounting seat 723 is coaxially arranged with the valve plug through hole on the packaging baffle 60, and the valve plug column 721 is movably arranged in the mounting seat 723. The valve plug column 721 and / or the mounting seat 723 are provided with a water sealing structure. By providing the water sealing structure, the wire scraps can be further prevented from entering the installation chamber 501 with the washing water, so that the centrifugal drainage mechanism 70 is in a wire scrap-free environment, reducing the possibility of wire scrap attachment and winding.

[0194] As shown in Figure 2 , Figure 4 , Figure 5 , the middle part of the connecting rod 712 is provided with a rotating shaft hole or a rotating shaft, the mounting seat 723 is extended close to the side of the counterweight 711 and is provided with a rotating shaft support, the rotating shaft support is rotationally supported with the rotating shaft hole of the connecting rod 712, and when the counterweight 711 rotates up and down around the fulcrum of the rotating shaft support and the connecting rod 712 under the action of the centrifugal force, the valve plug 722 is driven to move up and down in the second space between the lower side wall of the packaging baffle 60 and the inner wall of the inner cylinder 40, so as to open or close the drainage port 401.

[0195] Further, as shown in Figure 2 , Figure 6 , the packaging baffle 60 is injection molded with a first bolt column, the inner wall of the shell 50 is injection molded with a second bolt column 54, and the packaging baffle 60 is threadedly connected with the second bolt column 54 through the first bolt column and the bolt 605, so as to be tightly installed at the lower side opening of the partition baffle 56.

[0196] The above is only the preferred embodiment of the present application, not any form of limitation on the present application, although the present application has been disclosed as above with the preferred embodiment, however, it is not intended to limit the present application, any person skilled in the art can make some changes or modifications to the above-mentioned technical content with the above-mentioned technical content without departing from the technical solution range of the present application, and any simple modification, equivalent change and modification of the above-mentioned embodiment according to the technical essence of the present application are still within the scope of the present application.
