Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laundry equipment, in particular to a laundry lifting device for a washing machine and the washing machine. BACKGROUND

[0002] In the prior art, the outer cylinder of the drum washing machine contains water, and the inner cylinder rotates to wash. Holes are arranged on the inner cylinder wall for feeding washing water into the inner cylinder or for dehydrating the clothes in the inner cylinder. The washing water flows between the inner and outer cylinders for a long time, causing dirt and scale to accumulate between the inner and outer cylinders, resulting in a large number of bacteria breeding, secondary pollution of the clothes, and a serious threat to the health of consumers. In addition, the water filling between the inner and outer cylinders is a waste of water. Therefore, a non-hole inner cylinder washing machine has been designed. Since the inner cylinder is not only used to contain washing water, but also rotates to beat and wash the clothes in the cylinder, how to set up a dehydration structure and a drainage structure suitable for the above washing machine has become a difficult problem to be solved urgently.

[0003] A Chinese patent application with the application number 201810163971.6 discloses an inner cylinder lifting rib and a self-cleaning washing machine. The inner cylinder lifting rib includes a lifting rib body extending along the inner cylinder side wall structure line. The body is a shell structure with an open bottom and is buckled to the inner side wall of the inner cylinder. The inner part of the body is hollow to form an installation cavity for installing a sealing valve. The lower side of the lifting rib is provided with two vertical downward extending limiting ribs in the installation cavity. The two limiting ribs are separated by a certain gap, and the counterweight block of the sealing valve moves in the gap. The counterweight block generates a corresponding opening of the drainage port under the action of centrifugal force. The valve plug column can also be pulled back to the original position by the return spring, and the valve core corresponds to the drainage port. In this way, the centrifugal force of the high-speed rotation of the inner cylinder is used to act on the valve plug column, and the drainage port is opened and closed correspondingly.

[0004] The self-cleaning washing machine disclosed in the above application solves the problem of drainage of the non-hole drum washing machine by using a sealing valve for centrifugal drainage. However, it has the following defects: there is no effective buffer structure in the lifting rib body or on the counterweight block. The counterweight block is easy to hit the side wall of the lifting rib body or the inner wall of the inner cylinder when it is in centrifugal motion. Not only will it produce a lot of noise, affecting the user's experience, but also it will damage the structure of the sealing valve in the long run, shortening the service life of the sealing valve.

[0005] Therefore, the present application is proposed. SUMMARY

[0006] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a laundry lifting device for a washing machine. By providing a buffer structure in the installation cavity in the lifting shell and / or on the counterweight part, the problem of noise caused by the counterweight part hitting the side wall of the installation cavity or the inner cylinder when it is in centrifugal motion is effectively solved.

[0051] The present application will be further described in detail below with reference to the embodiments.

[0052] Example One

[0053] The present embodiment provides a laundry lifting device for a washing machine, mainly to solve the problem that the counterweight part of the centrifugal drainage mechanism arranged in the lifting shell is easy to hit the inner drum or the mounting chamber or the side wall of the lifting shell when doing centrifugal motion, producing noise.

[0054] As shown in Figures 1 to 6 The present embodiment provides a laundry lifting device for a washing machine, comprising:

[0055] The lifting shell 50 has an open cavity inside;

[0056] The centrifugal drainage mechanism 70 is arranged in the lifting shell 50, comprising a centrifugal part 71 and a valve plug part 72 connected with the centrifugal part 71;

[0057] The centrifugal part 71 comprises a counterweight part 711 capable of producing centrifugal motion under the action of centrifugal force, and the counterweight part 711 drives the valve plug part 72 to act under centrifugal motion;

[0058] The cavity of the lifting shell 50 has a mounting chamber 501 for mounting the centrifugal drainage mechanism 70, and the mounting chamber 501 and / or the counterweight part 711 is provided with a buffer structure.

[0059] The laundry lifting device for washing machines provided by the application effectively avoids the noise caused by the impact of the counterweight part 711 on the inner drum 40 or the side wall of the mounting chamber 501 due to the centrifugal movement of the counterweight part 711, and the phenomenon of affecting the user experience, and the buffer structure can also protect the counterweight part 711 and prolong the service life of the centrifugal drainage mechanism 70.

[0060] Further, the lifting shell 50 is provided with an encapsulation baffle 60 near the open end, and the encapsulation baffle 60 divides the cavity of the lifting shell 50 to form a mounting chamber 501 for mounting the centrifugal part 71. The structure and setting mode of the mounting chamber 501 and the encapsulation baffle 60 are described in detail in Embodiment Two.

[0061] As shown in Figures 1 to 5 The centrifugal part 71 is arranged in the mounting chamber 501 above the encapsulation baffle 60, and the buffer structure includes a first embossing structure 604 arranged on the encapsulation baffle 60 and outwardly recessed at the position corresponding to the counterweight part 711. The first embossing structure 604 arranged on the encapsulation baffle 60 provides a larger buffer space for the downward movement of the counterweight part 711, so as to avoid the impact of the counterweight part 711 on the encapsulation baffle 60 due to the limited movement space of the counterweight part 711 and the generation of larger noise.

[0062] Further, the first embossing structure 604 includes an embossing peripheral wall and an embossing bottom wall 6044 protruding from the lower surface of the encapsulation baffle 60, and the shape and size of the embossing bottom wall 6044 are matched with the shape and size of the cross section of the counterweight part 711. The first embossing structure 604 provides sufficient buffer space for the entire counterweight part 711, protects the counterweight part 711, and avoids the impact of the counterweight part 711 on the encapsulation baffle 60 and the generation of noise.

[0063] Further, the centrifugal drainage mechanism 70 further includes a valve plug part 72 connected to the counterweight part 711 through a lever structure, and the counterweight part 711 generates centrifugal movement under the action of centrifugal force, drives the valve plug part 72 to act, and opens the drainage port 401 on the inner drum 40 to drain water.

[0064] As shown in Figure 3 and Figure 4As shown, the first pressing structure 604 is provided with a buffer taper angle 6043 for avoiding the lever structure on the side close to the valve plug component 72. The cross section of the first pressing structure 604 is similar to the shape of a pencil head. The first pressing structure 604 is provided with a top corner structure gradually extending to the side of the valve plug component 72 corresponding to the position of the lever structure, forming the buffer taper angle 6043. The buffer taper angle 6043 can avoid the lever structure, and provide more buffer space for the counterweight part 711.

[0065] Further, as shown in Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 As shown, the buffer structure further includes a buffer missing angle of the counterweight part 711 away from the side of the valve plug component 72. The end missing angle of the counterweight part 711 away from the valve plug component 72 can provide more buffer space for the falling of the counterweight part 711, so as to ensure that the centrifugal drainage mechanism 70 has sufficient activity space to open or close the drainage port 401.

[0066] Preferably, in the embodiment, as shown in Figure 5 、 Figure 6 The counterweight part 711 is in the shape of a quadrangular prism. The buffer missing angle is a cut corner structure 7113 below the end of the counterweight part 711 away from the valve plug component 72. The cut corner structure 7113 has an inclined wall surface extending from the bottom wall of the counterweight part 711 to the left end wall of the counterweight part 711.

[0067] Further, as shown in Figure 1 、 Figure 6 The buffer structure further includes a first buffer pad 713 provided outside the bottom wall of the counterweight part 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 buffer protection of the counterweight part 711.

[0068] The first buffer pad 713 can be wrapped outside the entire bottom wall of the counterweight part 711. The first buffer pad 713 can be fixed on the counterweight part 711 by bonding or clamping.

[0069] Preferably, the bottom wall of the counterweight part 711 includes a flat wall surface and an inclined wall surface formed by the cut corner structure 7113. In order to save materials, the first buffer pad 713 is wrapped and arranged at the position between the flat wall surface and the inclined wall surface.

[0070] Because the junction of the flat wall and the inclined wall will first come into contact with the encapsulation baffle 60 when the counterweight 711 falls, the above design is adopted to cover the junction of the flat wall and the inclined wall within the first buffer pad 713, which can effectively buffer and shock absorb while minimizing the amount of material.

[0071] 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.

[0072] Furthermore, such as Figures 1 to 6 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.

[0073] Preferably, a buffer pad mounting position is provided on the 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 bottom wall 6044, or flush with it.

[0074] 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.

[0075] Furthermore, such as Figures 1 to 4 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 lifting 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.

[0076] Preferably, a one-way valve is installed in the drain hole 6042. The one-way valve is configured to allow water in the installation chamber 501 to be drained through the drain hole 6042, but prevent water in the inner cylinder 40 from entering the installation chamber 501 through the drain hole 6042, thereby further ensuring the sealing effect of the installation chamber 501.

[0077] Further, in another development, the top wall 51 of the lifting housing 50 is provided with a second embossed structure protruding upward at a position corresponding to the position of the counterweight part 711. The buffer structure further includes a second embossed structure providing a buffer space for the upward movement of the counterweight part 711. The second embossed structure can effectively prevent the counterweight part 711 from colliding with the top wall 51 of the lifting housing 50 and generating a large noise when the counterweight part 711 is in centrifugal motion.

[0078] In addition, the initial position of the counterweight part 711 can be raised correspondingly by the second embossed structure, which also provides a larger buffer space for the downward movement of the counterweight part 711.

[0079] The embodiment also provides a washing machine with the laundry lifting device.

[0080] The inner cylinder 40 is configured to independently hold washing water when washing laundry, and the side wall is provided with a drain port 401.

[0081] The laundry lifting device is installed on the inner wall of the inner cylinder 40 at a position corresponding to the position of the drain port 401.

[0082] The centrifugal drainage mechanism 70 is installed in the lifting housing 50 of the laundry lifting device to block and close the drain port 401. The centrifugal drainage mechanism 70 can open the drain port 401 to drain water under the action of centrifugal force.

[0083] Example Two

[0084] The embodiment provides an improved laundry lifting device for a washing machine based on the first embodiment, which is mainly used to solve the problem that the components of the centrifugal drainage mechanism installed in the existing laundry lifting device are prone to be attached and entangled with lint, causing the centrifugal drainage mechanism to not close properly or not to drain water normally.

[0085] As shown in Figures 1-6 The embodiment provides a laundry lifting device for a washing machine, which includes:

[0086] The lifting housing 50 has an open cavity inside.

[0087] The centrifugal drainage mechanism 70 is installed in the lifting housing 50, as shown in Figure 1 ,Figure 5 As shown, the initial state of the centrifugal drainage mechanism 70 is closed state, blocking the drainage port 401 on the inner cylinder 40, as shown in Figure 2 、 Figure 5 As shown, the centrifugal drainage mechanism 70 can act to open the drainage port 401 under the action of centrifugal force to drain water;

[0088] As shown in Figure 1 、 Figure 2 And Figure 6 As shown, the cavity of the lifting shell 50 is spaced apart from the independently closed installation chamber 501, and the centrifugal drainage mechanism 70 is at least partially installed in the installation chamber 501.

[0089] Because the lifting shell 50 is provided with a water inlet 521 for the washing water in the inner cylinder 40 to flow into the lifting shell 50, the cavity of the lifting shell 50 is in communication with the inside of the inner cylinder 40, and the centrifugal drainage mechanism 70 is directly installed in the cavity of the lifting shell 50. During the washing process, lint inevitably enters the lifting shell 50 along with the water flow, and then enters the centrifugal drainage mechanism 70.

[0090] In this embodiment, the centrifugal drainage mechanism 70 is installed in the independently closed installation chamber 501 additionally provided in the cavity of the lifting shell 50, which can play a role in secondary blocking of lint entering the centrifugal drainage mechanism 70. The lint in the inner cylinder 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, fundamentally avoiding the possibility of lint attachment and entanglement, and effectively ensuring the reliability of the centrifugal drainage mechanism 70.

[0091] Further, a plurality of partitions are fixedly provided in the lifting shell 50, and the installation chamber 501 is spaced apart from the independently closed installation chamber 501 by the partitions. The partitions can be integrally injection molded with the lifting shell 50 to form the independently closed installation chamber 501; or the partitions can be integrally connected with the lifting shell 50 by a connecting piece to form the independently closed installation chamber 501.

[0092] Specifically, the partitions include a partitioning baffle that separates the cavity of the lifting shell 50 to form the installation chamber 501 with an open lower end, and a packaging baffle 60 that is packaged on the open lower end of the partitioning baffle to form the independently closed installation chamber 501, and the centrifugal component 71 of the centrifugal drainage mechanism 70 is arranged in the installation chamber 501.

[0093] By setting the partitioning baffle and the encapsulating baffle 60 in the lifting shell 50, a mounting chamber 501 is spaced in the cavity of the lifting shell 50, and the centrifugal component 71 of the centrifugal drainage mechanism 70 is arranged in the mounting chamber 501. The partitioning baffle and the encapsulating baffle 60 serve to prevent the lint from entering the mounting chamber 501 along with the washing water.

[0094] In the embodiment, the encapsulating baffle 60 and the partitioning baffle can be closed plate structures, so that the mounting chamber 501 is a sealed chamber, and the water in the inner drum 40 cannot enter the mounting chamber 501, thereby preventing the lint from entering the mounting chamber 501.

[0095] Alternatively, in another solution, the encapsulating baffle 60 and the partitioning baffle can also be plate structures with a plurality of filter holes. The encapsulating baffle 60 and the partitioning baffle serve to filter the lint in the washing water twice. The water in the inner drum 40 can enter the mounting chamber 501 through the filter holes, but the lint cannot enter the mounting chamber 501.

[0096] Preferably, the encapsulating baffle 60 and the partitioning baffle in the embodiment are closed plate structures, which can effectively prevent the washing water from entering the mounting chamber 501 while preventing the lint from entering the mounting chamber 501, thereby further ensuring the reliability of the centrifugal drainage mechanism 70.

[0097] Further, the lifting shell 50 includes a top wall 51 and a peripheral side wall 52 connected between the top wall 51 and the inner wall of the inner drum 40 of the washing machine. The distance between the encapsulating baffle 60 and the top wall 51 of the lifting shell 50 is less than the distance between the top wall 51 of the lifting shell 50 and the inner wall of the inner drum 40.

[0098] The bottom wall of the encapsulating baffle 60 has a gap space with the inner wall of the inner drum 40. The gap space between the lower wall of the encapsulating baffle 60 and the inner wall of the inner drum 40 forms a drainage chamber 503 for draining the washing water. The drainage chamber 503 is in communication with the inner portion of the inner drum 40 and the drainage port 401 on the inner drum 40, respectively. The washing water in the inner drum 40 can enter the drainage port 401 on the inner drum 40 through the drainage chamber 503 and then be drained from the drainage port 401.

[0099] As Figure 1 , Figure 2 , Figure 5As shown, the partitioning baffle comprises a first baffle 611 and a second baffle 612 oppositely arranged inside the lifting housing 50 along the length direction of the lifting housing 50, the first baffle 611 and the second baffle 612 are respectively connected to the top wall 51 and the peripheral side wall 52 of the lifting housing 50, and the first baffle 611 and the second baffle 612 are integrally injection molded with the lifting housing 50.

[0100] The relative distance between the first baffle 611 and the second baffle 612 is less than the length of the lifting housing 50, and the length of the mounting chamber 501 is less than the length of the lifting housing 50 along the length direction of the lifting housing 50.

[0101] Preferably, the mounting chamber 501 is located close to one side end of the lifting housing 50, which can provide more installation space for installing the filter component in the lifting housing 50 compared to being arranged at the middle position of the lifting housing 50.

[0102] Further, as shown, Figure 2 、 Figure 3 、 Figure 6 As shown, the peripheral 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 arranged to form a water inlet 521 corresponding to the notch for water inlet, and the water inlet 521 is communicated with the water outlet 401 on the inner cylinder 40 and the inner chamber of the inner cylinder 40.

[0103] The notch corresponding to the lower edges of the first side wall and the second side wall is provided with the gap, and the gap has a certain axial extension length, and the gap has a long strip shape. The packaging baffle 60 is embedded and installed in the notch of the first side wall and the second side wall.

[0104] The upper edges of the first baffle 611 and the second baffle 612 are connected to the top wall 51 of the lifting housing 50, and the two side edges are respectively connected to the first side wall and the second side wall of the lifting housing 50.

[0105] Preferably, the lifting housing 50 further comprises a third baffle 613, the first baffle 611 and the third baffle 613 are arranged close to the two side ends of the lifting housing 50, and the first baffle 611 / second baffle 612 is spaced apart by three spaces in the cavity of the lifting housing 50, and the spaces located on the outer sides of the first baffle 611 / second baffle 612 are used for independently arranging the mounting structure of the lifting housing 50.

[0106] The first side wall and the lower edge of the second side wall of the lifting housing 50 between the first baffle 611 and the third baffle 613 are provided with a gap, and the packaging baffle 60 is installed in the installation position formed by the first baffle 611, the second baffle 612, the first side wall and the second side wall. The second baffle 612 is arranged in the lifting 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 packaging baffle 60. Taking the installation chamber 501 arranged in the lifting housing 50 close to the cylinder opening end of the inner cylinder 40 as an example, the first baffle 611 is arranged close to the cylinder opening side, and the second baffle 612 and the inner wall surface of the packaging baffle 60 form the installation chamber 501.

[0107] In an embodiment, as shown in the drawings, the laundry lifting device provided by the embodiment is provided with a special-shaped grid blocking rib 603 capable of making the washing drain water flow through at a certain bending angle at positions corresponding to the water inlet 521 below both sides of the packaging baffle 60. When the washing water flows through the water inlet 521, the lint is blocked and attached to the special-shaped grid blocking rib 603 and cannot enter the drain cavity 503. Figures 3 to 6

[0108] Preferably, the special-shaped grid blocking rib 603 is a plurality of special-shaped grid blocking ribs arranged at intervals along the two long edges of the packaging baffle 60. Through the plurality of special-shaped grid blocking ribs arranged at intervals along the two long edges of the packaging baffle 60, the lint can be effectively blocked from entering the drain cavity 503 to block the drain opening 401, and the phenomenon that the lint is attached to the centrifugal drain mechanism 70 or blocks the drain opening 401 to affect normal drainage is avoided.

[0109] Further, the special-shaped grid blocking rib 603 is an arc-shaped grid rib with an arc-shaped bending angle, for example, the special-shaped grid blocking rib 603 can be a forward “S” shape or a reverse “S” shape; or the special-shaped grid blocking rib 603 is a folded grid rib with a straight bending angle, for example, the special-shaped grid blocking rib 603 can be a “<” or “>” shape; when the washing water flows through the special-shaped grid blocking rib 603, the lint is blocked at the arc-shaped bending angle or the straight bending angle of the special-shaped grid blocking rib 603 and cannot enter the drain cavity 503.

[0110] Further, the gap space between the adjacent two special-shaped grid blocking ribs 603 forms a flow guide channel. The bending angle is arranged to form an arc-shaped reversing flow guide channel between the inlet and the outlet of the flow guide channel, which plays a role in blocking and filtering lint and plays a role in reversing and increasing the flow rate of water flow.

[0111] ​Preferably, the outlet end of the special-shaped lattice ribs 603 is bent or folded towards the drain port 401 to guide the water flow to converge towards the drain port 401.

[0112] For example, the special-shaped lattice ribs 603 are arc-shaped lattice ribs in the shape of a positive "S" or a negative "S", the arc-shaped lattice rib below the left side of the drain port 401 is in the shape of a positive "S", the arc-shaped lattice rib below the right side of the drain port 401 is in the shape of a negative "S", the arc-shaped lattice rib above the left side of the drain port 401 is in the shape of a negative "S", and the arc-shaped lattice rib above the right side of the drain port 401 is in the shape of a positive "S".

[0113] For another example, the special-shaped lattice ribs 603 are zigzag-shaped lattice ribs in the shape of "<" or ">", the zigzag-shaped lattice rib below the left side of the drain port 401 is in the shape of a positive "<", the arc-shaped lattice rib below the right side of the drain port 401 is in the shape of ">", the arc-shaped lattice rib above the left side of the drain port 401 is in the shape of a negative "<", and the arc-shaped lattice rib above the right side of the drain port 401 is in the shape of a positive ">".

[0114] Through the above design, the gap space between the two special-shaped lattice ribs 603 forms a flow guide channel outlet end towards the direction of the drain port 401, facilitating the convergence of the water flow.

[0115] Preferably, the arc-shaped lattice rib / zigzag-shaped lattice rib has a plurality of arc-shaped turning angles / flat bending angles, and the water flow is bent multiple times through the plurality of turning angles or bending angles, and the effect of blocking the lint is better.

[0116] Alternatively, the arc-shaped lattice rib / zigzag-shaped lattice rib is a multi-layer structure arranged in an up-down staggered manner, and the water flow is bent multiple times through the plurality of arc-shaped lattice ribs / zigzag-shaped lattice ribs, and the effect of blocking the lint is better.

[0117] In the above scheme, the arc-shaped lattice rib / zigzag-shaped lattice rib is arranged in an up-down staggered manner, the upper arc-shaped lattice rib / zigzag-shaped lattice rib is arranged between the two lattice ribs of the lower layer, and if the lint passes through the flow guide channel between the two lattice ribs of the lower layer, the upper lattice rib can play a role in blocking the lint from passing through again, further avoiding the lint from entering the drain cavity 503 of the lifting shell 50.

[0118] In another embodiment, the special-shaped lattice 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 arranged in an interlaced manner, and the plurality of guide ribs arranged on both sides of the longitudinal ribs form a bending flow guide channel, which plays an effective role in blocking the lint.

[0119] The guide ribs can be horizontal transverse ribs. Preferably, the guide ribs are inclined ribs that are inclined towards the direction of the outlet of the flow guide channel, and play a role of guiding water flow.

[0120] More preferably, the guide ribs at the outlet end of the flow guide channel are inclined towards the direction of the drain opening 401 of the inner cylinder 40, so as to facilitate the collection and discharge of water flow towards the drain opening 401.

[0121] The laundry lifting device for the washing machine provided in the embodiment can effectively block lint from entering the drain cavity 503 and plugging the drain opening 401, and avoid the phenomenon that lint adheres to the centrifugal drainage mechanism 70 or is plugged at the drain opening 401, thereby affecting normal drainage.

[0122] Further, the first spacing space formed between the packaging baffle 60 and the inner wall of the lifting shell 50 is the mounting chamber 501. The second spacing space is formed between the outer wall of the baffle and the inner wall of the lifting shell 50 and the inner wall of the inner cylinder 40 located at the outer periphery of the drain opening 401, and the second spacing space is respectively in communication with the inside of the inner cylinder 40 and the drain opening 401 formed on the inner cylinder 40. The water in the inner cylinder 40 flows through the second spacing space and is discharged through the drain opening 401.

[0123] Preferably, the second spacing space includes the drain cavity 503 located below the packaging baffle 60, the mounting chamber 501 is located at the position close to the end of the lifting shell 50, and the second spacing space further includes the filter cavity 502 formed between the outer side of the first baffle 611 / second baffle 612 and the inner wall of the lifting shell 50, and the filter structure is installed in the filter cavity 502.

[0124] As shown in Figure 1 、 Figure 2 and Figure 6 in the embodiment, the filter cavity 502 is formed by the space between the right side surface of the second baffle 612 and the inner wall surface of the lifting shell 50, a plurality of through holes are formed on the top wall 51 or the peripheral side wall 52 of the lifting 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 lifting shell 50. The filter cavity 502 exchanges water flow with the water in the inner cylinder 10 through the through holes formed on the lifting shell 50, and the drain cavity 503 guides the water in the inner cylinder 40 to the drain opening 401 formed on the inner cylinder 40.

[0125] Further, as shown in Figure 1 、 Figure 5As shown, the centrifugal drainage mechanism 70 further comprises a valve plug component 72, which comprises a valve plug post 721 coaxially arranged with the drainage port 401 and a valve plug 722 connected to the lower end of the valve plug post 721. In the natural state, the valve plug 722 is blocked at the drainage port 401 to ensure the sealing of the inner cylinder 40. The encapsulation baffle 60 is provided with a valve plug through hole corresponding to the position of the drainage port 401, which can be passed through by the valve plug post 721.

[0126] The centrifugal component 71 comprises a counterweight part 711 located in the mounting chamber 501 and a connecting part 712, one end of which is fixedly connected with the counterweight part 711, and the other end is hingedly connected with the upper end of the valve plug post 721. The middle part of the connecting part 712 is rotatably supported and fixed, forming a lever structure.

[0127] The hinged point of the connecting part 712 and the valve plug post 721 is located in the mounting chamber 501. Under the action of centrifugal force, the counterweight part 711 moves downward, which will drive the valve plug post 721 to move upward by the lever principle, and then the valve plug 722 opens the drainage port 401 on the inner cylinder 40 to drain water.

[0128] The hinged points of the counterweight part 711 and the connecting part 712 of the centrifugal component 71, and the connecting part 712 and the valve plug post 721 are all provided in the mounting chamber 501, which effectively avoids the possibility of wire scraps being attached to the hinged position of the counterweight part 711 or the connecting part 712 and the valve plug post 721, affecting the normal work of the centrifugal drainage mechanism 70.

[0129] Preferably, a sleeve-shaped mounting seat 723 is mounted on the upper side of the encapsulation baffle 60, the inner through hole of the mounting seat 723 is coaxially arranged with the valve plug through hole on the encapsulation baffle 60, and the valve plug post 721 is movably arranged in the mounting seat 723. The valve plug post 721 and / or the mounting seat 723 are provided with a water sealing structure. By setting the water sealing structure, it can further prevent wire scraps from entering the mounting chamber 501 with washing water, so that the centrifugal drainage mechanism 70 is in a wire-free environment, reducing the possibility of wire scraps being attached and entangled.

[0130] As Figure 1 and Figure 2As shown, the middle part of the connecting part 712 is provided with a rotating shaft hole or rotating shaft, the mounting seat 723 extends close to the side of the counterweight part 711 and is provided with a rotating shaft support 724, the rotating shaft support 724 is rotationally supported and matched with the rotating shaft hole of the connecting part 712, when the counterweight part 711 rotates up and down around the fulcrum of the rotating shaft support 724 and the connecting part 712 under the action of centrifugal force, the valve plug 722 is driven to move up and down in the second interval 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 drain port 401.

[0131] Further, as shown in Figure 3 、 Figure 4 、 Figure 6 , the packaging baffle 60 is provided with a bolt hole, the inner wall of the lifting shell 50 is injection molded with a bolt column 53, the packaging baffle 60 is threadedly connected with the bolt column 53 through the bolt 605, and the packaging baffle 60 is tightly installed at the lower side opening of the partition baffle

[0132] Specifically, four bolt holes are respectively arranged at four corner positions of the packaging baffle 60, four downwardly extending bolt columns 53 are injection molded on the inner wall of the lifting shell 50, and the packaging baffle 60 is tightly installed at the lower end of the lifting shell 50 through the bolt 605.

[0133] Preferably, as shown in Figure 1 、 Figure 2 , the packaging baffle 60 is provided with a first flange 601 / second flange 602 that respectively abuts and limits the first baffle 611 / second baffle 612. The side edge of the packaging baffle 60 close to the first baffle 611 extends downward to form the first flange 601, the outer wall surface of the first flange 601 abuts and matches the inner wall surface of the first baffle 611, the second flange 602 that extends upward is arranged on the packaging baffle 60 at a position corresponding to the second baffle 612, the second flange 602 covers the lower edge of the second baffle 612, and the outer wall surface of the second baffle 612 abuts and matches the inner wall surface of the second flange 602.

[0134] Through the structures of the first flange 601 and the second flange 602, the packaging baffle 60 tightly matches the first baffle 611 and the second baffle 612, the sealing effect at the junction position is ensured through the face-to-face abutment contact mode, and the metal filings are prevented from entering the installation chamber 501 from the connection position of the first baffle 611 and the second baffle 612 and the packaging baffle 60 along with the washing water.

[0135] The embodiment also provides a washing machine with the above-mentioned clothes lifting device, which comprises:

[0136] an inner cylinder 40;

[0137] An inner drum door is installed on the drum opening of the inner drum 40, and cooperates with the inner drum 40 to form an independent washing chamber when closed, and independently holds washing water when washing clothes.

[0138] A drain port 401 is arranged on the sidewall of the inner drum 40, and the clothes lifting device is installed on the inner wall of the inner drum 40 at the drain port 401, and the centrifugal drainage mechanism 70 can close / open the drain port 401.

[0139] Example Three

[0140] The embodiment is an improved scheme for the centrifugal drainage mechanism in the clothes lifting device based on Embodiment One or Embodiment Two, mainly to solve the problems of easy rusting and corrosion of the counterweight part and poor stability between the counterweight part and the connecting part.

[0141] As shown in Figures 1-6 , the centrifugal drainage mechanism 70 provided by the embodiment includes a centrifugal part 71 and a valve plug part 72, the centrifugal part 71 includes a counterweight part 711 and a connecting part 712, and the counterweight part 711 includes a counterweight block shell 7112 and a counterweight block 7111 arranged in the counterweight block shell 7112.

[0142] By additionally arranging the counterweight block shell 7112 outside the counterweight block 7111, the counterweight block shell 7112 covers the counterweight block 7111, effectively avoiding direct contact between the counterweight block 7111 and the washing water, which is easy to rust and corrode and affects the normal work of the centrifugal drainage mechanism 70. The counterweight block shell 7112 also plays a certain protective role, avoiding damage to the counterweight block 7111 during centrifugal movement.

[0143] As shown in Figure 1 , Figure 2 and Figure 5 , one end of the connecting part 712 of the centrifugal drainage mechanism 70 is connected with the counterweight block shell 7112, the other end is rotationally connected with the valve plug part 72, the middle part of the connecting part 712 is rotationally supported and fixed, forming a lever structure, and the connecting part 712 is connected and fixed with the counterweight block shell 7112, which is more easily processed and formed than being directly connected and fixed with the counterweight block 7111. The counterweight block 7111 produces centrifugal movement under the action of centrifugal force, driving the valve plug part 72 to act to open the drain port 401 on the inner drum 40 for drainage.

[0144] Further, as shown in Figure 1 , Figure 2As shown, the connecting portion 712 is connected to one end of the valve plug member 72 and gradually expands outward to connect to one end of the weight block shell 7112. By connecting one end of the valve plug member 72 to one end of the weight block shell 7112 in a gradually expanding manner, the connecting area of the connecting portion 712 and the weight block shell 7112 is increased, so that the strength between the connecting portion 712 and the weight block shell 7112 is higher and the stability is better.

[0145] Further, in this embodiment, the connecting portion 712 is a plate-shaped structure with a triangular cross-section, and one side of the connecting portion 712 is fixedly connected to the side wall of the weight block shell 7112 near the valve plug member 72.

[0146] The connecting portion 712 can be a right triangle, and one right angle side of the connecting portion 712 is fixedly connected to the outer wall surface of the weight block shell 7112. The width of the connecting portion 712 gradually increases from the end connected to the valve plug member 72 to the end connected to the weight block shell 7112. The stability of the triangle is higher, and the connecting area of the connecting portion 712 and the weight block shell 7112 is larger, so the stability is better.

[0147] Preferably, the longitudinal cross-section of the connecting portion 712 is triangular, and the connecting portion 712 is a longitudinally arranged triangular plate-shaped structure. Compared with the connecting portion 712 being arranged as a transversely arranged triangular plate-shaped structure, the connecting portion 712 requires the least space for movement when the weight portion 711 rotates up and down, thereby improving the space utilization in the lifting shell 50.

[0148] Further, in combination with Figure 1 , Figure 5 As shown, a reinforcing structure for improving strength is arranged at the connecting position of the connecting portion 712 and the weight block shell 7112, and the reinforcing structure is a plate-shaped reinforcing rib 7121 connected between the connecting portion 712 and the weight block shell 7112.

[0149] Preferably, the plate-shaped reinforcing rib 7121 is at least two and is arranged on the left and right sides of the connecting portion 712. The plate-shaped reinforcing rib 7121 is triangular, and the adjacent two sides are respectively connected to the connecting portion 712 and the weight block shell 7112.

[0150] By arranging the plate-shaped reinforcing rib 7121 on both sides of the connecting portion 712, the strength of the connecting portion 712 and the weight block shell 7112 at the connecting position is further improved, effectively avoiding the phenomenon of easy fracture at the connecting position of the connecting portion 712 and the weight portion 711.

[0151] Further, as shown in Figure 5As shown, the connecting portion 712 has a protruding extension connecting rib 7122 arranged on the upper edge of the connecting portion 712, which extends from the upper edge of the connecting portion 712 to the direction of the weight portion 711; the extension connecting rib 7122 has a certain extension length, and the lower side of the extension connecting rib 7122 is fixedly connected with the upper side wall of the weight block shell 7112.

[0152] The extension connecting rib 7122 is fixedly connected with the upper side and the right side of the weight block shell 7112, which further increases the stability of the connection between the connecting portion 712 and the weight block shell 7112.

[0153] Further, in the embodiment, the weight block shell 7112 and the connecting portion 712 are connected and fixed by melting or bonding, and preferably, the weight block shell 7112 and the connecting portion 712 are integrally formed by injection molding, and the weight block shell 7112 and the connecting portion 712 are integrally injection molded.

[0154] Further, the weight block shell 7112 has a closed accommodating cavity arranged therein for accommodating the weight block 7111, the weight block 7111 is made of metal material, and the weight block shell 7112 is made of non-metal material with corrosion resistance, so that the weight block shell 7112 will not rust and corrode.

[0155] Preferably, the weight block shell 7112 is made of high-hardness plastic material, which not only has good corrosion resistance, but also has strong weight, thereby reducing the weight of the inner cylinder 40.

[0156] Further, along the length direction of the weight block 7111, the weight block shell 7112 includes an open peripheral side wall at both ends, and a first end side wall and a second end side wall arranged at both ends of the peripheral side wall, and one end of the connecting portion 712 is fixedly connected with the first end side wall / second end side wall.

[0157] The peripheral side wall of the weight block shell 7112 includes a first side wall, a second side wall, a third side wall and a fourth side wall connected in sequence, and the first side wall, the second side wall, the third side wall and the fourth side wall are smoothly connected at the respective connecting positions, and the adjacent side walls are smoothly connected, thereby avoiding the straight angle connection and being easy to scratch other components.

[0158] Further, in an embodiment, a gap is provided between the outer wall of the counterweight shell 7112 and the counterweight 7111, and a sealing medium is filled in the gap. By filling the sealing medium in the gap between the outer wall of the counterweight shell 7112 and the counterweight 7111, the probability of the washing water entering the accommodation cavity of the counterweight shell 7112 and contacting the counterweight 7111 is further reduced.

[0159] Preferably, the sealing medium is glue, and the gap between the counterweight 7111 and the counterweight shell 7112 is filled with glue to bond the counterweight 7111 and the counterweight shell 7112 into one body. The sealing medium is glue, which not only has a sealing effect but also has a connecting and fixing effect, and bonds the counterweight 7111 and the counterweight shell 7112 into one body to avoid the phenomenon that the counterweight 7111 shakes up and down in the counterweight shell 7112.

[0160] The embodiment also provides a washing machine with the centrifugal drainage mechanism 70, which comprises:

[0161] The inner drum 40 independently holds washing water when washing clothes;

[0162] The clothes lifting device is installed on the drain port 401 of the inner wall of the inner drum 40;

[0163] The centrifugal drainage mechanism 70 is installed in the lifting shell 50 of the clothes lifting device to block and close the drain port 401, and the centrifugal drainage mechanism 70 can open the drain port 401 to drain water under the action of centrifugal force.

[0164] Example Four

[0165] In order to solve the problem that the filtering structure provided in the existing clothes lifting device cannot achieve self-cleaning effect and needs to be cleaned or replaced regularly, the embodiment provides a clothes lifting device for a washing machine on the basis of the first embodiment to the third embodiment, and mainly introduces the filtering structure in the lifting shell in detail.

[0166] The embodiment provides a clothes lifting device, and the filtering structure in the clothes lifting device can be self-cleaned, so that the filtering structure can be kept clean and the filtering effect can be ensured without manually cleaning the filtering structure.

[0167] As Figures 1 to 6As shown, the clothes lifting device provided by the embodiment includes a lifting shell 50 arranged on the inner wall of the inner cylinder 4, the lifting shell 50 constitutes the outer contour of the clothes lifting device, and an inner cavity is formed between the lifting shell 50 and the inner wall of the inner cylinder 4. The lifting shell 50 is provided with a through hole for water inflow and outflow, so that the water in the inner cylinder can flow into the inner cavity of the clothes lifting device through the through hole, and the water flow in the inner cavity of the clothes lifting device can flow out of the inner cavity through the through hole. The filter structure is arranged in the inner cavity, so that the water flowing through the inner cavity of the clothes lifting device can be filtered by the filter structure. A plurality of water outlets 401 for discharging water in the inner cylinder are arranged on the inner wall of the inner cylinder 4, and the inner cavity covers at least one water outlet 401. Such arrangement enables the water flow to flow into the inner cavity of the clothes lifting device through the through hole on the lifting shell 50 and then be discharged through the water outlet 401. That is, the water discharge flow in the inner cylinder includes a water discharge path from the through hole to the water outlet 401. Since the inner cavity covers at least one water outlet 401, the inner cavity at least includes one water discharge path as described above, and the filter structure is arranged in the inner cavity, so that the water discharge path can pass through the filter structure in the inner cavity. In this way, the filter structure can be washed by the water discharge flowing along the water discharge path, so as to wash away the lint and other impurities remaining on the filter structure by the water flow, thereby achieving the effect of cleaning the filter structure.

[0168] As shown in Figures 1 to 3 , and Figure 5 , Figure 6 , the filter structure arranged in the filter cavity 502 includes a filter screen, a comb-shaped filter structure 5021 and other filter structures. In order to enable the water in the inner cylinder 4 to wash the filter structure and be filtered by the filter structure, the position of the filter structure arranged in the inner cavity should also be reasonable, which is beneficial to the filtering process of the filter structure and the washing away of the lint and other impurities remaining thereon. The filter structure includes a filter cross section for intercepting impurities in the water flow. After the filtering process, the impurities will adhere to the filter cross section. In order to ensure the filtering effect of the filter structure, the washing water flow needs to flow through the filter cross section, and when the filter structure is washed by the water discharge flow, the water discharge flow also needs to flow through the surface of the filter cross section to wash away the lint and other impurities remaining on the filter cross section. The filter cross section can be the cross section of the filter screen or the cross section of the comb-shaped filter structure 5021 that can intercept the lint and other impurities, such as the through hole provided in the top wall of the lifting shell 50, and each row of comb-shaped protrusions forms a plane for intercepting impurities parallel to the top wall 51 of the lifting shell 50 where the through hole is arranged. The cross section of these filter structures is used as the filter cross section to intercept the lint and other impurities. The direction of the water flow at the position of the filter cross section in the inner cavity forms an included angle with the filter cross section. In this way, the washing water flow and the water discharge flow will definitely flow through the filter cross section, so that the washing water flow is filtered by the filter cross section and the water discharge flow can wash away the lint and other impurities remaining on the surface of the filter cross section.

[0169] Preferably, the water flow direction at the position of the filtering section in the inner cavity is perpendicular to the filtering section. Preferably, the flushing water flow and the drainage water flow are perpendicular to the filtering section, so that the flushing water flow and the drainage water flow have the maximum contact area with the filtering section, which is more conducive to the filtration of the flushing water flow, and the drainage water flow can flush away the impurities in the process of flowing. The above-mentioned impurity blocking plane only needs to be flushed by the drainage water flow to flush away the impurities thereon, so the drainage water flow and the flushing water flow at the position of the filtering section intersect with the filtering section. Or if it is other types of filtering structure, the drainage water flow and the flushing water flow also need to flow at the position of the filtering section.

[0170] More preferably, the filtering section is arranged parallel to the top wall 51 of the lifting shell 50 on which the through holes are arranged. Since the through holes are arranged on the top wall 51 of the lifting shell 50 for water inlet, the filtering section is arranged parallel to the top wall 51, so that the water flow entering from the through holes on the top wall 51 is perpendicular to the filtering section. And no matter it is the flushing water flow or the drainage water flow, it enters the inner cavity from the through holes, and the filtering section is arranged at the position parallel to the top wall 51 on which the through holes are arranged, so that the drainage water flow entering the inner cavity is more easily flushed to the filtering section, and the flushing water flow entering the inner cavity can be filtered. And the filtering section is projected to the top wall 51, and the projection covers at least part of the through holes on the top wall 51; preferably, the projection covers all the through holes on the top wall 51. In this way, the water flow entering from the through holes on the top wall 51 can flow to the filtering section. That is, for the filter screen, the filter screen needs to be arranged parallel to the top wall 51, so that the drainage water flow flowing from the through holes on the top wall 51 can directly flow to the filter screen, so as to achieve the effect that the flushing water flow is filtered by the filter screen and the filter screen is flushed by the drainage water flow.

[0171] More preferably, the filtering section is arranged at a position close to the top wall 51 in the filtering cavity 502. Since the through holes for water inlet are arranged on the top wall 51, the filtering section is arranged close to the top wall 51, so that the filtering section is close to the through holes for water inlet. The water flow entering the inner cavity is certainly greater close to the water inlet, so that the filtering section is arranged close to the through holes for water inlet, so that the filtering section can be flushed by a larger water flow, and thus it is beneficial to clean the impurities such as thread scraps remaining on the filtering structure. And the water flow at the position of the through holes has the maximum flow rate, so that the filtering section is arranged on the top wall 51 close to the through holes, so that the filtering section can filter more water flow entering the inner cavity, and thus a better filtering effect can be achieved.

[0172] Specifically, the second baffle 612 is arranged in the laundry lifting device to guide the flow of the drainage water flow and the washing water flow, the top wall 51 of the lifting shell 50 is provided with through holes, the inner wall of the inner drum 4 surrounds the filter cavity 502 which covers at least part of the through holes on the top wall 51, and the filter structure is arranged in the filter cavity 502. That is, the filter cavity 502 is connected with the drainage port 401 on the inner wall of the inner drum 4 and the through holes of the lifting shell 50 to drain the water in the inner drum 4. In addition, the filter structure is arranged in the filter cavity 502. Therefore, when the water in the inner drum of the washing machine flows along the filter cavity 502, the filter structure in the filter cavity 502 can be cleaned. The position and structure of the laundry lifting device on the inner wall of the inner drum 4 in the embodiment are reasonable, so that the inner cavity of the laundry lifting device can form the filter cavity 502 for guiding the drainage water flow and the washing water flow. The washing water flow can flow through the filter structure under the guidance of the filter cavity 502 and be filtered by the filter structure, and the drainage water flow can flow through the filter structure under the guidance of the filter cavity 502. In this way, the filter structure can be automatically cleaned by the water flow of the drainage water in the inner drum.

[0173] As can be seen from the above, the drainage water flow in the filter cavity 502 is the water supply for cleaning the filter structure, and the water flow in the filter cavity 502 should be sufficient during drainage. Therefore, a partition plate type structure can be arranged in the inner cavity of the laundry lifting device. The partition plate type structure can surround the filter cavity 502, so that the filter cavity 502 with the partition plate type structure can make the drainage flow along a set trajectory. As shown in FIGS. 1, Figure 2 、 Figure 6 The filter structure is arranged between the second baffle 612 and the third baffle 613; preferably, the area between the second baffle 612 and the third baffle 613 covers all the through holes on the top wall 51. The second baffle 612 and the third baffle 613 are partition plate type guide structures. By limiting the second baffle 612 and the third baffle 613, the drainage water flow and the washing water flow can only flow within the range between the second baffle 612 and the third baffle 613. If the flow range of the drainage water flow is too wide, the impact force of the drainage water flow will be insufficient, which will affect the cleaning effect of the filter structure.

[0174] Since the drainage port 401 is located outside the second baffle 612, the second baffle 612, the top wall 51 and the inner wall of the inner drum 4 cannot surround the above-mentioned closed filter cavity 502, because this will make the drainage water flow unable to flow into the drainage port 401. Therefore, the filter cavity 502 needs to be provided with at least an opening 5022, so that the drainage water flow can flow into the drainage port 401 through the opening 5022.

[0175] Specifically as Figure 1 、 Figure 2As shown, the second baffle 612 has a gap between its end wall near the drain outlet 401 and the inner wall of the inner cylinder 4. This gap forms an opening 5022 for water to flow from the inner cavity to the drain outlet 401, allowing the drainage water to flow out through the opening 5022 and eventually be discharged through the drain outlet 401. 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 in the filter chamber 502 to gather at the drain outlet 401, resulting in a larger water flow to 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. Since the water flow contains debris such as lint that obstructs the flow of water after cleaning the filter structure, the guide plate 5023 is installed to make the water flow more concentrated, thereby making the water flow to the drain 401 larger, and making it easier for lint and other debris to be discharged from the drain 401.

[0176] Specifically, such as Figures 1 to 3 , Figure 5 As shown, the 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.

[0177] The garment lifting device provided in this embodiment has a reasonable internal structure, which allows the rinsing water entering the garment lifting device to be filtered by the filter structure; the drainage water cleans the filter structure inside the garment lifting device, achieving the purpose of washing away residual lint and other impurities on the filter structure, and ensuring the filtration effect of the filter structure. That is, the garment lifting device provided by this invention can self-clean the filter structure, so that the filter structure can be self-cleaned by the drainage inside the inner cylinder 40 without manual cleaning.

[0178] The implementation schemes in the above embodiments can be further combined or replaced, and the embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention. Various changes and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the design concept of the present invention shall fall within the protection scope of the present invention.
