Description

Technical Field

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

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

[0003] The Chinese invention patent application, application number 201810163971.6, discloses an inner drum lifting rib and a no-clean washing machine. The rib comprises a lifting rib body extending along the structural line of the inner drum sidewall. The body is a shell structure with an open lower side that snaps onto the inner drum sidewall. The body is hollow inside to form a mounting cavity for installing a sealing valve. The lifting rib is provided with a water passage structure that guides wash water in the inner drum into the mounting cavity. The outer periphery of the lifting rib body is in contact with the inner drum sidewall and is provided with at least one notch to allow wash water in the inner drum to flow through the notch into the mounting cavity.

[0004] The no-clean washing machine proposed in the above application solves the drainage problem of the hole-free drum washing machine by using a sealing valve for centrifugal drainage. However, since the hollow installation cavity inside the lifting rib body is connected to the interior of the inner drum, the washing water in the inner drum flows into the installation cavity from the notch. During the washing process, it is inevitable that lint will enter the lifting rib body with the water flow, and then enter the sealing valve. In particular, the counterweight block of the sealing valve, or the position where the counterweight block is hinged to the upper end of the valve plug, is extremely susceptible to lint adhesion and entanglement. Not only is it difficult to remove, but it also seriously affects the normal operation of the sealing valve, causing the sealing valve to not close properly, dripping or leaking, or the lint interferes with the normal opening of the centrifugal drainage mechanism, affecting the normal drainage of the washing machine.

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

[0054] The present invention will be further described in detail below with reference to the embodiments.

[0055] Example 1

[0056] This embodiment provides a clothes lifting device for a washing machine, which is mainly intended to solve the problem that the various components of the centrifugal drainage mechanism installed in the existing clothes lifting device are easily attached with lint, causing the centrifugal drainage mechanism to not close properly or fail to drain normally.

[0057] like Figure 1-6 As shown, this embodiment provides a clothes lifting device for a washing machine, comprising:

[0058] A lifting shell 50 having an open cavity therein;

[0059] The centrifugal drainage mechanism 70 is installed in the lifting shell 50, as shown in FIG. Figure 1 、 Figure 5 As shown, the initial state of the centrifugal drainage mechanism 70 is the closed state, which blocks and closes the drainage port 401 on the inner cylinder 40. Figure 2 、 Figure 5 As shown, the centrifugal drainage mechanism 70 can be operated to open the drainage port 401 to drain water under the action of centrifugal force;

[0060] Combine Figure 1 、 Figure 2as well as Figure 6 As shown, an independently enclosed installation chamber 501 is separated in the cavity of the lifting shell 50 , and the centrifugal drainage mechanism 70 is at least partially installed in the installation chamber 501 .

[0061] Since the lifting shell 50 is provided with a water inlet 521 for the washing water in the inner drum 40 to flow into the lifting shell 50, the cavity of the lifting shell 50 is connected to the interior of the inner drum 40, and the centrifugal drainage mechanism 70 is directly installed in the cavity of the lifting shell 50. During the washing process, it is inevitable that lint will enter the lifting shell 50 with the water flow and then enter the centrifugal drainage mechanism 70.

[0062] In this embodiment, the centrifugal drainage mechanism 70 is installed by additionally providing an independently enclosed installation chamber 501 in the cavity of the lifting shell 50. The installation chamber 501 can play a secondary role in blocking wire chips from entering the centrifugal drainage mechanism 70. The wire chips 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 wire chip-free environment, fundamentally avoiding the possibility of wire chips adhering to and entangled, and effectively ensuring the reliability of the operation of the centrifugal drainage mechanism 70.

[0063] Furthermore, a plurality of partitions are fixedly installed in the lifting housing 50, and an independent and enclosed installation chamber 501 is separated by the partitions in the lifting housing 50. The partitions can be integrally injection-molded with the lifting housing 50 to form the independent and enclosed installation chamber 501; or the partitions can be connected to the lifting housing 50 via connectors to form the independent and enclosed installation chamber 501.

[0064] Specifically, the partition includes a partition baffle that separates the cavity of the lifting shell 50 to form an installation chamber 501 with an opening at the lower end, and an encapsulation baffle 60 that is encapsulated on the lower end opening of the partition baffle to form an independently enclosed installation chamber 501, and the centrifugal component 71 of the centrifugal drainage mechanism 70 is arranged in the installation chamber 501.

[0065] By arranging a partition baffle and an encapsulation baffle 60 in the lifting shell 50, an independently enclosed installation chamber 501 is separated in the cavity of the lifting shell 50, and the centrifugal component 71 of the centrifugal drainage mechanism 70 is arranged in the installation chamber 501. The partition baffle and the encapsulation baffle 60 play a secondary role in blocking impurities and lint from entering the installation chamber 501 along with the washing water.

[0066] In this embodiment, the encapsulation baffle 60 and the partition baffle can be closed plate structures, so that the installation chamber 501 is a sealed chamber, and the water in the inner cylinder 40 will not enter the installation chamber 501, thereby preventing wire scraps and impurities from entering the installation chamber 501.

[0067] Alternatively, in another embodiment, the encapsulation baffle 60 and the partition baffle may also be a plate-like structure having a plurality of filter holes. The encapsulation baffle 60 and the partition baffle play the role of secondary filtration of lint in the washing water. The water in the inner drum 40 may enter the installation chamber 501 through the filter holes, but the lint will be blocked outside and will not enter the installation chamber 501.

[0068] Preferably, the encapsulation baffle 60 and the partition baffle in this embodiment are closed plate structures, which can not only prevent the wire scraps from entering the installation chamber 501, but also effectively prevent the washing water from entering the installation chamber 501, further ensuring the reliability of the centrifugal drainage mechanism 70.

[0069] Furthermore, 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 washing machine inner drum 40, and the distance between the encapsulation baffle 60 and the top wall 51 of the lifting shell 50 is smaller than the distance between the top wall 51 of the lifting shell 50 and the inner wall of the inner drum 40.

[0070] There is a gap between the bottom wall of the packaging baffle 60 and the inner wall of the inner drum 40. The gap space formed between the lower wall of the packaging baffle 60 and the inner wall of the inner drum 40 is a drainage cavity 503 for discharging washing water. The drainage cavity 503 is respectively connected to the inside of the inner drum 40 and the drainage port 401 on the inner drum 40. The washing water in the inner drum 40 can enter the drainage port 401 on the inner drum 40 through the drainage cavity 503 and then be discharged from the drainage port 401.

[0071] like Figure 1 、 Figure 2 、 Figure 5 As shown, the partition baffle includes a first baffle 611 and a second baffle 612 relatively arranged inside the lifting shell 50 along the length direction of the lifting shell 50, and 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 shell 50, and the first baffle 611 and the second baffle 612 are injection molded as one piece with the lifting shell 50.

[0072] The relative distance between the first baffle 611 and the second baffle 612 is smaller than the length of the lifting shell 50 . Along the length direction of the lifting shell 50 , the length of the installation chamber 501 is smaller than the length of the lifting shell 50 .

[0073] Preferably, the installation chamber 501 is located near one end of the lifting shell 50 , which can provide a larger installation space for installing the filter component in the lifting shell 50 compared to being located in the middle of the lifting shell 50 .

[0074] Furthermore, if Figure 2 、 Figure 3 、 Figure 6 As shown, the peripheral side wall 52 includes 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 at least partially corresponding to the notches to form a water inlet 521 for water intake, and the water inlet 521 connects the drain outlet 401 on the inner tube 40 and the internal chamber of the inner tube 40.

[0075] The lower edges of the first side wall and the second side wall are correspondingly provided with the notches, the notches have a certain axial extension length, and are in the shape of a long strip. The packaging baffle 60 is embedded in the notches of the first side wall and the second side wall.

[0076] The upper edges of the first baffle 611 and the second baffle 612 are connected to the top wall 51 of the lifting shell 50 , and the side edges thereof are respectively connected to the first side wall and the second side wall of the lifting shell 50 .

[0077] Preferably, a third baffle 613 is also provided in the lifting shell 50, and the first baffle 611 and the third baffle 613 are arranged at positions close to the two side ends of the lifting shell 50. The first baffle 611 / the second baffle 612 separate three spaces in the cavity of the lifting shell 50, and the spaces located on both sides of the first baffle 611 / the second baffle 612 are used for independently setting up the installation structure of the lifting shell 50.

[0078] The lower edges of the first and second side walls of the lifting housing 50 between the first baffle 611 and the third baffle 613 are notched, and the encapsulating baffle 60 is installed within the mounting position formed by the first and second baffles 611, 612, and the first and second side walls. The second baffle 612 is disposed within the lifting housing 50 between the first and third baffles 611, 613, with the lower edge of the second baffle 612 extending to the upper wall surface of the encapsulating baffle 60. For the purpose of explanation, the installation chamber 501 is located within the lifting housing 50 near the barrel end of the inner barrel 40. The first baffle 611 is disposed near the barrel end, and the installation chamber 501 is formed between the second baffle 612, the first baffle 611, and the inner wall surface of the encapsulating baffle 60.

[0079] In one embodiment, Figures 3 to 6As shown, the clothing lifting device provided in this embodiment is provided with special-shaped grid retaining ribs 603 corresponding to the water inlet 521 on both sides of the lower part of the packaging baffle 60, which can allow the washing discharge water to flow through at a certain bending angle. When the washing water flows through the water inlet 521, the lint will be blocked and attached to the special-shaped grid retaining ribs 603 and will not enter the drainage cavity 503.

[0080] Preferably, the special-shaped grid retaining ribs 603 are multiple and are arranged at intervals along the two long edges of the packaging baffle 60. By arranging the multiple special-shaped grid retaining ribs 603 at intervals on the two long edges of the packaging baffle 60, it is possible to effectively prevent wire scraps from entering the drainage chamber 503 and blocking the drainage outlet 401, thereby avoiding the wire scraps from adhering to the centrifugal drainage mechanism 70 or blocking the drainage outlet 401, thereby affecting normal drainage.

[0081] Furthermore, the special-shaped grid retaining rib 603 is an arc-shaped grid retaining rib with an arc-shaped bend corner, for example, the special-shaped grid retaining rib 603 can be a forward "S" or reverse "S" shape; or, the special-shaped grid retaining rib 603 is a folded grid retaining rib with a straight bend corner, for example, the special-shaped grid retaining rib 603 can be a "<" or ">" shape; when the washing water flows through the special-shaped grid retaining rib 603, the wire scraps will be blocked at the arc-shaped bend corner or the straight bend corner of the special-shaped grid retaining rib 603 and will not enter the drainage cavity 503.

[0082] Furthermore, the gap space between two adjacent special-shaped grid ribs 603 forms a diversion channel, and by setting the bending angle, the diversion channel forms an arc-shaped reversing diversion channel from the inlet to the outlet, which on the one hand blocks and filters the wire scraps, and on the other hand increases the water flow rate by reversing.

[0083] Preferably, the outlet end of the special-shaped grid retaining rib 603 is bent or curved toward the drain outlet 401 to guide the drainage water to converge toward the drain outlet 401 .

[0084] For example, the special-shaped grid retaining rib 603 is an arc-shaped grid rib in a positive "S" shape or a reverse "S" shape, then the arc-shaped grid rib located at the lower left side of the drain outlet 401 is in a positive "S" shape, the arc-shaped grid rib located at the lower right side of the drain outlet 401 is in a reverse "S" shape, the arc-shaped grid rib located above the left side of the drain outlet 401 is in a reverse "S" shape, and the arc-shaped grid rib located above the right side of the drain outlet 401 is in a positive "S" shape.

[0085] For another example, the special-shaped grid retaining rib 603 is a folded grid rib in the shape of "<" or ">", then the folded grid rib located at the lower left side of the drain outlet 401 is in the positive "<" shape, the arc-shaped grid rib located at the lower right side of the drain outlet 401 is in the shape of ">", the arc-shaped grid rib located at the upper left side of the drain outlet 401 is in the negative "<" shape, and the arc-shaped grid rib located at the upper right side of the drain outlet 401 is in the positive ">" shape.

[0086] Through the above design, the gap space between the two special-shaped grid retaining ribs 603 forms a diversion channel with the outlet end facing the drain outlet 401, which is convenient for the collection of water flow.

[0087] Preferably, the arc-shaped grid ribs / folded grid ribs respectively have multiple arc-shaped bending angles / straight bending angles. By setting multiple bending angles or bending angles, the water flow is bent multiple times, and the effect of blocking wire chips is better.

[0088] Alternatively, the arcuate grid ribs / folded grid ribs are a multi-layer structure with upper and lower layers staggered. By arranging multiple layers of arcuate grid ribs / folded grid ribs, the water flow is bent multiple times, and the effect of blocking wire chips is better.

[0089] Moreover, in the above scheme, the arc-shaped grid ribs / folded grid ribs are staggeredly arranged between the upper and lower layers, and the upper-layer arc-shaped grid ribs / folded grid ribs are arranged between the two grid ribs of the lower layer. If the wire scraps pass through the guide channel between the two grid ribs of the lower layer, the grid ribs of the upper layer can play a secondary role in blocking the passage of the wire scraps, further preventing the wire scraps from entering the drainage cavity 503 of the lifting shell 50.

[0090] In another embodiment, the special-shaped grid retaining rib 603 includes longitudinal ribs and multiple guide ribs arranged on both sides of the longitudinal ribs. The guide ribs on two adjacent longitudinal ribs are staggered and interspersed. By forming a curved diversion channel through the multiple guide ribs arranged on both sides of the longitudinal ribs, it plays a role in effectively blocking wire chips.

[0091] The guide ribs are horizontal ribs. Preferably, the guide ribs are inclined, and are inclined toward the outlet of the guide channel, so as to guide the water flow.

[0092] More preferably, the guide ribs at the outlet end of the diversion channel are inclined toward the drain outlet 401 of the inner tube 40 , so as to facilitate the water flow to be collected and discharged toward the drain outlet 401 .

[0093] The clothes lifting device for a washing machine provided in this embodiment can effectively prevent lint from entering the drainage chamber 503 and blocking the drainage port 401 by providing a special-shaped grid retaining rib 603 at the water inlet 521 of the lifting shell 50, which allows the washing discharge water to flow through at a certain bending angle, thereby avoiding the lint from adhering to the centrifugal drainage mechanism 70 or blocking the drainage port 401 and affecting normal drainage.

[0094] Furthermore, the first space formed between the encapsulating baffle 60, the partitioning baffle, and the inner wall of the lifting shell 50 serves as the installation chamber 501. A second space is formed between the outer wall of the baffle, the inner wall of the lifting shell 50, and the inner wall of the inner tube 40 located outside the drain port 401. The second space is connected to the interior of the inner tube 40 and the drain port 401 provided on the inner tube 40, respectively. Water in the inner tube 40 flows through the second space and is discharged from the drain port 401.

[0095] Preferably, the second partition space includes a drainage chamber 503 located below the packaging baffle 60, the installation chamber 501 is located near the end position of the lifting shell 50, and the second partition space also includes a filter chamber 502 formed between the outer side of the first baffle 611 / second baffle 612 and the inner wall of the lifting shell 50, and a filtering structure is installed in the filter chamber 502.

[0096] like Figure 1 、 Figure 2 as well as Figure 6 As shown, in this embodiment, the filter chamber 502 is formed by the space between the right side of the second baffle 612 and the inner wall of the lifting housing 50. Multiple through-holes are provided on the top wall 51 or the peripheral side wall 52 of the lifting housing 50, corresponding to the filter chamber 502. These through-holes communicate with the filter chamber 502. Preferably, the through-holes are provided on the top wall 51 of the lifting housing 50. The filter chamber 502 exchanges water with the water in the inner drum 10 through the through-holes provided in the lifting housing 50. The drainage chamber 503 drains the water in the inner drum 40 toward the drainage port 401 provided therein.

[0097] Furthermore, if Figure 1 、 Figure 5 As shown, the centrifugal drainage mechanism 70 also includes a valve plug component 72, which 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 a natural state, the valve plug 722 is sealed at the drain port 401 to ensure the sealing of the inner tube 40. A valve plug through hole is provided on the packaging baffle 60 corresponding to the drain port 401, through which the valve plug column 721 can pass.

[0098] The centrifugal component 71 includes a counterweight portion 711 and a connecting portion 712 located in the installation chamber 501. One end of the connecting portion 712 is fixedly connected to the counterweight portion 711, and the other end is hinged to the upper end of the valve plug column 721. The middle part of the connecting portion 712 is rotatably supported and fixed to form a lever structure.

[0099] The hinge point between the connecting portion 712 and the valve plug 721 is located within the mounting chamber 501. The counterweight 711 moves downward under the action of centrifugal force, and through the principle of leverage, it drives the valve plug 721 upward, thereby causing the valve plug 722 to open the drain port 401 on the inner cylinder 40 for drainage.

[0100] The counterweight portion 711 and the connecting portion 712 of the centrifugal component 71, as well as the hinge point between the connecting portion 712 and the valve plug 721 are all arranged in an installation chamber 501, which effectively prevents wire scraps from being entangled and attached to the counterweight portion 711 or the hinge position between the connecting portion 712 and the valve plug 721, thereby affecting the normal operation of the centrifugal drainage mechanism 70.

[0101] Preferably, a sleeve-shaped mounting seat 723 is mounted on the upper side of 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. The valve plug 721 is disposed in the mounting seat 723 so as to be movable up and down. A water-sealing structure is provided on the valve plug 721 and / or the mounting seat 723. The water-sealing structure further prevents lint from entering the installation chamber 501 along with the wash water, thereby maintaining the centrifugal drainage mechanism 70 in a lint-free environment and reducing the possibility of lint adhering to and becoming entangled.

[0102] like Figure 1 and Figure 2 As shown, a rotating shaft hole or rotating shaft is provided in the middle of the connecting part 712, and a rotating shaft bracket 724 is extended from the mounting seat 723 near the side of the counterweight part 711. The rotating shaft bracket 724 is rotationally supported and cooperated 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 bracket 724 and the connecting part 712 under the action of centrifugal force, it drives the valve plug 722 to move up and down in the second interval space between the lower side wall of the packaging baffle 60 and the inner wall of the inner cylinder 40, thereby opening or closing the drain outlet 401.

[0103] Furthermore, if Figure 3 、 Figure 4 、 Figure 6As shown, the encapsulated baffle 60 is provided with a bolt hole, and the inner wall of the lifting shell 50 is injection-molded with a bolt column 53. The encapsulated baffle 60 is threadedly connected to the bolt column 53 through the bolt hole by a bolt 605, and the encapsulated baffle 60 is fastened to the lower opening of the partition baffle.

[0104] Specifically, four bolt holes are respectively provided at the four corners of the packaging baffle 60 , and four downwardly extending bolt columns 53 are correspondingly injection-molded on the inner wall of the lifting shell 50 , and the packaging baffle 60 is fastened to the lower end of the lifting shell 50 by bolts 605 .

[0105] Preferably, if Figure 1 、 Figure 2 As shown, the packaging baffle 60 is provided with a first flange 601 and a second flange 602, which respectively abut and limit with the first baffle 611 and the second baffle 612. The side edge of the packaging baffle 60 adjacent to the first baffle 611 extends downward to form the first flange 601, and the outer wall surface of the first flange 601 closely abuts and fits with the inner wall surface of the first baffle 611. The packaging baffle 60 is provided with an upwardly extending second flange 602 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 closely abuts and fits with the inner wall surface of the second flange 602.

[0106] By setting the first flange 601 and the second flange 602 structure, the packaging baffle 60 is tightly matched with the first baffle 611 and the second baffle 612. The surface-to-surface contact method ensures the sealing effect at the junction position, preventing wire scraps from entering the installation chamber 501 along with the washing water from the connection position between the first baffle 611 and the second baffle 612 and the packaging baffle 60.

[0107] This embodiment also provides a washing machine having the above-mentioned clothes lifting device, comprising:

[0108] Inner cylinder 40;

[0109] The inner drum door is openably mounted on the opening of the inner drum 40. When the inner drum door is closed, it forms an independent washing chamber with the inner drum 40 to independently hold washing water when washing clothes.

[0110] A drain port 401 is provided on the side wall of the inner drum 40 , and the clothing lifting device is mounted on the drain port 401 on the inner wall of the inner drum 40 . The centrifugal drainage mechanism 70 can close / open the drain port 401 .

[0111] Example 2

[0112] This embodiment is an improvement to the centrifugal drainage mechanism 70 based on the first embodiment, and is mainly intended to solve the problems of the existing counterweight portion 711 being prone to rust and corrosion and the poor stability between the counterweight portion 711 and the connecting portion 712 .

[0113] like Figure 1-6 As shown, the centrifugal drainage mechanism 70 provided in this embodiment includes a centrifugal component 71 and a valve plug component 72. The centrifugal component 71 includes a counterweight portion 711 and a connecting portion 712. The counterweight portion 711 includes a counterweight block shell 7112 and a counterweight block 7111 arranged in the counterweight block shell 7112.

[0114] The counterweight housing 7112 is provided outside the counterweight 7111, and the counterweight housing 7112 covers the counterweight 7111, thereby effectively preventing the counterweight 7111 from directly contacting the washing water, which would easily cause rust and corrosion, and affect the normal operation of the centrifugal drainage mechanism 70. The counterweight housing 7112 also plays a certain protective role, preventing the counterweight 7111 from being damaged during the centrifugal movement.

[0115] like Figure 1 、 Figure 2 as well as Figure 5 As shown, the connection portion 712 of the centrifugal drainage mechanism 70 is connected to the counterweight housing 7112 at one end and rotatably connected to the valve plug component 72 at the other end. The middle portion of the connection portion 712 is rotatably supported and fixed to form a lever structure. The connection portion 712 is fixed to the counterweight housing 7112, which is easier to process and form than directly connecting to the counterweight 7111. The counterweight 7111 generates centrifugal motion under the action of centrifugal force, driving the valve plug component 72 to open the drain port 401 on the inner cylinder 40 for drainage.

[0116] Furthermore, if Figure 1 、 Figure 2 As shown, the connecting portion 712 is gradually expanded outward from one end connected to the valve plug component 72 to the end connected to the counterweight housing 7112. By gradually expanding outward from one end connected to the valve plug component 72 to the end connected to the counterweight housing 7112, the connection area between the connecting portion 712 and the counterweight housing 7112 is increased, making the strength and stability between the connecting portion 712 and the counterweight housing 7112 higher.

[0117] Furthermore, in this embodiment, the connecting portion 712 is a plate-like structure with a triangular cross-section, and one side edge of the connecting portion 712 is connected and fixed to the side wall of the counterweight shell 7112 close to the valve plug component 72.

[0118] The connecting portion 712 can be in the shape of a right-angled triangle, with a right-angled side of the connecting portion 712 connected and fixed to the outer wall surface of the counterweight shell 7112. The width of the connecting portion 712 gradually increases from the end connected to the valve plug component 72 to the end connected to the counterweight shell 7112. The triangle has higher stability, and the area where the connecting portion 712 is connected to the counterweight shell 7112 is larger, and the stability is better.

[0119] Preferably, the longitudinal cross-section of the connecting portion 712 is triangular in shape, and the connecting portion 712 is a longitudinally arranged triangular plate-like structure. Compared with setting the connecting portion 712 as a transversely arranged triangular plate-like structure, the connecting portion 712 requires the smallest movable space when rotating up and down with the counterweight portion 711, thereby improving the space utilization rate within the lifting shell 50.

[0120] Further, combined with Figure 1 、 Figure 5 As shown, a reinforcement structure for improving strength is provided at the connection position between the connection portion 712 and the counterweight shell 7112 . The reinforcement structure is a plate-shaped reinforcement rib 7121 connected between the connection portion 712 and the counterweight shell 7112 .

[0121] Preferably, there are at least two plate-shaped reinforcement ribs 7121, which are provided on the left and right sides of the connecting portion 712. The plate-shaped reinforcement ribs 7121 are triangular in shape, with two adjacent sides connected to the connecting portion 712 and the counterweight shell 7112, respectively.

[0122] By providing plate-shaped reinforcing ribs 7121 on both sides of the connecting portion 712, the strength of the connection between the connecting portion 712 and the counterweight shell 7112 is further strengthened, effectively avoiding the phenomenon of easy breakage at the connection position between the connecting portion 712 and the counterweight portion 711.

[0123] Further, if Figure 5 As shown, the connecting portion 712 has a protruding extended connecting rib 7122, and the extended connecting rib 7122 is formed by extending from the upper edge of the connecting portion 712 toward the counterweight portion 711; the extended connecting rib 7122 has a certain extension length, and the lower side surface of the extended connecting rib 7122 is fixedly connected to the upper side wall of the counterweight block shell 7112.

[0124] The extended connecting rib 7122 is provided to fix the counterweight shell 7112 from its upper side, and the counterweight shell 7112 is connected and fixed from both the upper side and the right side of the counterweight shell 7112, thereby further increasing the stability of the connection between the connecting portion 712 and the counterweight shell 7112.

[0125] Furthermore, in this embodiment, the counterweight shell 7112 and the connecting portion 712 are connected and fixed by melting or bonding. Preferably, the counterweight shell 7112 and the connecting portion 712 are integrally formed by injection molding, and the counterweight shell 7112 and the connecting portion 712 are an integral injection molded part.

[0126] Furthermore, the counterweight shell 7112 has a closed accommodating cavity for accommodating the counterweight 7111. The counterweight 7111 is made of metal material, and the counterweight shell 7112 is made of corrosion-resistant non-metallic material. The counterweight shell 7112 will not rust or corrode.

[0127] Preferably, the counterweight shell 7112 is made of a high-hardness plastic material, which is not only corrosion-resistant but also heavy, thereby reducing the load on the inner cylinder 40 .

[0128] Furthermore, along the length direction of the counterweight block 7111, the counterweight block shell 7112 includes a peripheral side wall with open 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 part 712 is connected and fixed to the first end side wall / second end side wall.

[0129] The peripheral side walls of the counterweight shell 7112 include a first side wall, a second side wall, a third side wall and a fourth side wall which are connected end to end in sequence. The first side wall, the second side wall, the third side wall and the fourth side wall are connected with each other at their respective connections in a smooth transition manner, and the adjacent side walls are connected with each other in a smooth transition manner to avoid right-angle connections which are easy to be scratched by other parts.

[0130] Furthermore, in one embodiment, there is a gap between the counterweight shell 7112 and the outer wall of the counterweight 7111, and the gap is filled with a sealing medium. By filling the gap between the counterweight shell 7112 and the outer wall of the counterweight 7111 with the sealing medium, the probability of washing water entering the accommodating cavity of the counterweight shell 7112 and contacting the counterweight 7111 is further reduced.

[0131] Preferably, the sealing medium is colloid, 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 together. The use of colloid as the sealing medium not only provides a sealing effect but also serves as a connecting and fixing function, bonding the counterweight 7111 and the counterweight shell 7112 together to prevent the counterweight 7111 from shaking up and down within the counterweight shell 7112.

[0132] This embodiment further provides a washing machine having the centrifugal drainage mechanism 70, comprising:

[0133] The inner drum 40 is used to independently hold washing water when washing clothes;

[0134] A clothing lifting device, the clothing lifting device being installed on the drain outlet 401 on the inner wall of the inner drum 40;

[0135] The centrifugal drainage mechanism 70 is installed in the lifting shell 50 of the clothing lifting device to block and close the drainage port 401. The centrifugal drainage mechanism 70 can open the drainage port 401 to drain water under the action of centrifugal force.

[0136] Example 3

[0137] This embodiment provides a clothes lifting device for a washing machine based on the first and / or second embodiments, mainly to solve the problem that the counterweight part 711 of the centrifugal drainage mechanism 70 is prone to hit the inner drum 40 or the side wall of the installation chamber 501 during centrifugal motion, thereby generating noise.

[0138] like Figures 1 to 6 As shown, this embodiment provides a clothes lifting device for a washing machine, comprising:

[0139] A lifting shell 50 having an open cavity therein;

[0140] The centrifugal drainage mechanism 70 is provided in the lifting housing 50 and includes a centrifugal component 71 and a valve plug component 72 connected to the centrifugal component 71;

[0141] The centrifugal component 71 includes a counterweight portion 711 that can generate centrifugal motion under the action of centrifugal force. The centrifugal motion of the counterweight portion 711 drives the valve plug component 72 to move.

[0142] The cavity of the lifting shell 50 has an installation chamber 501 for installing the centrifugal drainage mechanism 70 , and a buffer structure is provided in the installation chamber 501 and / or on the counterweight portion 711 .

[0143] The clothes lifting device for a washing machine provided by the present invention effectively avoids the phenomenon of noise caused by the counterweight part 711 performing centrifugal movement and hitting the inner drum 40 or the side wall of the mounting chamber 501, thereby affecting the user experience, by providing a buffer structure in the mounting chamber 501 in the lifting shell 50 and / or on the counterweight part 711. At the same time, the buffer structure can also protect the counterweight part 711 and extend the service life of the centrifugal drainage mechanism 70.

[0144] Furthermore, a sealing baffle 60 is installed near the open end of the lifting housing 50. The sealing baffle 60 defines a mounting chamber 501 above the cavity of the lifting housing 50 for mounting the centrifugal component 71. The structure, arrangement, formation, and effects of the mounting chamber 501 and sealing baffle 60 are the same as those in the first embodiment, and therefore, will not be further described here.

[0145] like Figures 1 to 5 As shown, the centrifugal component 71 is disposed in the mounting chamber 501 above the packaging baffle 60. The buffer structure includes a first, outwardly recessed, pressure-profile structure 604 disposed on the packaging baffle 60 corresponding to the position of the counterweight 711. The downwardly recessed first, pressure-profile structure 604 disposed on the packaging baffle 60 provides a larger buffer space for the counterweight 711 to move downward, thereby preventing the counterweight 711 from hitting the packaging baffle 60 due to its limited movement space and generating loud noise.

[0146] Furthermore, the first profiled structure 604 includes a profiled peripheral wall protruding from the lower surface of the packaging baffle 60 and a profiled bottom wall 6044. The shape and size of the profiled bottom wall 6044 are adapted to the cross-sectional shape and size of the counterweight 711. The first profiled structure 604 provides sufficient buffer space for the entire counterweight 711, protecting the counterweight 711 while preventing it from colliding with the packaging baffle 60 and generating noise.

[0147] Furthermore, the centrifugal drainage mechanism 70 further includes a valve plug component 72 connected to the counterweight 711 via a lever structure. The counterweight 711 generates centrifugal motion under the action of centrifugal force, driving the valve plug component 72 to open the drain port 401 in the inner drum 40 for drainage. The lever structure is the connecting portion 712 in Embodiment 1 or Embodiment 2, and its specific structure and function are not further described here.

[0148] like Figure 3 and Figure 4 As shown, the first pressure-profile structure 604 extends near the valve plug component 72 and is provided with a buffer cone angle 6043 for avoiding the lever structure. The cross-section of the first pressure-profile structure 604 is shaped like a pencil head. The first pressure-profile structure 604 is provided with a top angle structure that gradually extends toward the valve plug component 72 at a position corresponding to the lever structure, forming the buffer cone angle 6043. The buffer cone angle 6043 can avoid the lever structure, providing the first pressure-profile structure 604 with a larger buffer space for the counterweight portion 711.

[0149] Further, if Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 As shown, the buffer structure also includes a buffer notch set on the side of the counterweight part 711 away from the valve plug component 72. The end notch of the counterweight part 711 away from the valve plug component 72 can provide a larger buffer space for the falling of the counterweight part 711 to ensure that the centrifugal drainage mechanism 70 has sufficient room for movement to open or close the drain port 401.

[0150] Preferably, in this embodiment, Figure 5 、 Figure 6 As shown, the counterweight portion 711 is in the shape of a quadrangular prism, and the buffer notch is a cut-angle structure 7113 below the end of the counterweight portion 711 away from the valve plug component 72. The cut-angle structure 7113 has an inclined wall surface extending from the bottom wall of the counterweight portion 711 to the left end wall of the counterweight portion 711.

[0151] Furthermore, if Figure 1 、 Figure 6 As shown, the buffer structure also includes a first buffer pad 713 arranged 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 is set to meet the design requirements of the buffer protection counterweight part 711.

[0152] The first buffer pad 713 may cover the entire bottom wall of the counterweight portion 711 , and the first buffer pad 713 may be fixed to the counterweight portion 711 by bonding or clamping.

[0153] Preferably, the bottom wall of the counterweight portion 711 includes a straight wall surface and an inclined wall surface formed by the cut-angle structure 7113. In order to save materials, the first buffer pad 713 is arranged to cover a position between the straight wall surface and the inclined wall surface.

[0154] Because the intersection of the straight wall and the inclined wall will first contact the packaging baffle 60 when the counterweight part 711 falls, the above design is adopted to enclose the intersection of the straight wall and the inclined wall in the first buffer pad 713, which plays an effective buffering and shock-absorbing protection role while minimizing material.

[0155] Alternatively, in another solution, the first buffer pad 713 is arranged outside the inclined wall surface of the cut-angle structure 7113, and the first buffer pad 713 has a certain elastic and retractable thickness.

[0156] Furthermore, if Figures 1 to 6As shown, the buffer structure also includes a second buffer pad 6041 arranged on the corrugated bottom wall 6044 of the first corrugated structure 604. The second buffer pad 6041 is arranged on the corrugated bottom wall 6044. In this way, when the counterweight part 711 falls, the first buffer pad 713 and the second buffer pad 6041, as well as the first corrugated structure 604, will play an effective role in buffering and shock absorption, thereby achieving the purpose of shock absorption and noise reduction for the counterweight part 711 from multiple angles.

[0157] Preferably, a buffer pad mounting position is provided on the profiled bottom wall 6044 at the junction of the angled structure 7113 of the counterweight portion 711 and the bottom wall of the counterweight portion 711, and the second buffer pad 6041 is embedded in the buffer pad mounting position, and the upper surface of the second buffer pad 6041 is slightly higher than the upper surface of the profiled bottom wall 6044, or is flush with it.

[0158] The buffer pad installation position can be a through installation hole opened in the profiled bottom wall 6044, or a blind hole. The second annular pad 6041 is embedded and extruded in the buffer pad installation position. The second buffer pad will not occupy the falling space of the counterweight part 711. At the same time, when the space in the first profiled structure 604 cannot provide enough buffer space for the counterweight part 711, the second buffer pad 6041 will play its role and provide a larger buffer space for the counterweight part 711. At the same time, even if the counterweight part 711 hits the second buffer pad 6041, it will not generate a lot of noise, further enhancing the buffering and noise reduction effect of the buffer structure.

[0159] Further, if Figures 1 to 4 As shown, one or more drain holes 6042 are provided on the bottom wall of the first corrugated structure 604 at intervals. If washing water accumulates in the installation chamber 501 of the lifting shell 50, it can be drained in time through the drain holes 6042. At the same time, since the corrugated bottom wall 6044 of the first corrugated structure 604 is the lowest position of the entire installation chamber 501, the drain holes 6042 are opened on the corrugated bottom wall 6044 of the first corrugated structure 604, which is more conducive to the collection and discharge of water.

[0160] Preferably, a one-way valve is installed in the drain hole 6042. Through the one-way valve, the water in the installation chamber 501 can be discharged through the drain hole 6042, but the water in the inner cylinder 40 cannot enter the installation chamber 501 from the drain hole 6042, further ensuring the sealing effect of the installation chamber 501.

[0161] Furthermore, in another embodiment, a second press-type structure protruding upward is provided on the top wall 51 of the lifting housing 50 at a position corresponding to the counterweight 711. The buffer structure also includes a second press-type structure that provides a buffer space for the rise of the counterweight 711. The second press-type structure effectively prevents the counterweight 711 from striking the top wall 51 of the lifting housing 50 during centrifugal motion, thereby generating loud noise.

[0162] Furthermore, by providing the second press-type structure, the initial position of the counterweight portion 711 can be raised accordingly, which is equivalent to providing a larger buffer space for the falling of the counterweight portion 711 .

[0163] This embodiment further provides a washing machine having the above-mentioned clothes lifting device, comprising:

[0164] The inner drum 40 is used to independently hold washing water when washing clothes, and a drain outlet 401 is provided on the side wall;

[0165] The clothing lifting device is installed on the inner wall of the inner drum 40 at the position corresponding to the drain outlet 401;

[0166] The centrifugal drainage mechanism 70 is installed in the lifting shell 50 of the clothing lifting device to block and close the drainage port 401. The centrifugal drainage mechanism 70 can open the drainage port 401 to drain water under the action of centrifugal force.

[0167] Example 4

[0168] In order to solve the problem that the filtering structure provided in the existing clothing lifting device cannot achieve the self-cleaning effect and needs to be cleaned or replaced regularly, this embodiment provides a clothing lifting device for a washing machine based on the first to third embodiments, and mainly introduces the filtering structure in the lifting shell in detail.

[0169] This embodiment provides a clothing lifting device, in which the filter structure inside the clothing lifting device can be self-cleaning, and the filter structure can be kept clean and the filtering effect can be guaranteed without manual cleaning of the filter structure.

[0170] like Figures 1 to 6As shown, the clothing lifting device provided in this embodiment includes a lifting shell 50 disposed on the inner wall of the inner drum 4. The lifting shell 50 forms the outer contour of the clothing lifting device, and an inner cavity is formed between the lifting shell 50 and the inner wall of the inner drum 4. The lifting shell 50 is provided with a through hole for water flow in and out, so that water in the inner drum can flow into the inner cavity of the clothing lifting device through the through hole, and water in the inner cavity of the clothing lifting device can flow out of the inner cavity through the through hole. A filtering structure is provided in the inner cavity, so that water flowing through the inner cavity of the clothing lifting device can be filtered and processed by the filtering structure. Multiple drain ports 401 are provided on the inner wall of the inner drum 4 to discharge water from the inner drum, and the inner cavity covers at least one drain port 401. This arrangement allows water to flow into the inner cavity of the clothing lifting device through the through hole in the lifting shell 50 and then be discharged through the drain port 401. That is, the drainage flow in the inner cylinder includes a drainage path flowing from the through hole to the drainage port 401. Since the inner cavity covers at least one drainage port 401, the inner cavity includes at least one drainage path as described above, and a filtering structure is provided in the inner cavity, so that the drainage path can pass through the filtering structure in the inner cavity. In this way, the drainage flowing along the drainage path can be used to flush the filtering structure, so that the drainage water flow can be used to wash away impurities such as lint remaining on the filtering structure, thereby achieving the effect of cleaning the filtering structure.

[0171] like Figures 1 to 3 ,as well as Figure 5 、 Figure 6 As shown in , the filtering structure provided in the filter cavity 502 includes a filter mesh, a comb-shaped filtering structure 5021 and other structures capable of filtering. In order to enable the water in the inner cylinder 4 to flush the filtering structure and pass through the filtering treatment of the filtering structure, the position of the filtering structure in the inner cavity should also be reasonable, which is conducive to the filtering treatment of the filtering structure and the washing away of debris such as residual wire scraps. The filtering structure includes a filtering section that intercepts debris in the water flow. After the debris is filtered during the filtering process, the filtering section will cause the debris to adhere to the filtering section. In order to ensure the filtering effect of the filtering structure, it is necessary to make the flushing water flow through the filtering section, and when the drainage water flow is used to flush the filtering structure, the drainage water flow also needs to flow through the surface of the filtering section to wash away impurities such as residual wire scraps on the filtering section. Among them, the filtering cross section can be the cross section of the filter screen; or it can be the cross section of the comb-shaped filtering structure 5021 that can intercept debris such as lint. For example, as shown in the figure, a through hole is provided on the top wall of the lifting shell 50, and each row of comb-shaped protrusions forms a plane for intercepting impurities that is parallel to the top wall 51 of the lifting shell 50 where the through hole is provided. The cross sections in these filtering structures are used as filtering cross sections to intercept impurities such as lint. The direction of the water flow at the position of the filtering cross section in the inner cavity forms an angle with the filtering cross section. In this way, the flushing water flow and the drainage water flow will definitely flow through the filtering cross section, and then the flushing water flow will be filtered through the filtering cross section, and the drainage water flow can wash away the lint and other debris remaining on the surface of the filtering cross section.

[0172] Preferably, the direction of the water flow in the inner cavity passing through the filter section is perpendicular to the filter section. Preferably, the flushing water flow and the drainage water flow are perpendicular to the filter section, so that the contact area between the drainage water flow and the flushing water flow and the filter section is maximized, which is more conducive to the filtration of the flushing water flow, and the drainage water flow washes away the debris during the flow. The above-mentioned plane that intercepts impurities only needs to be flushed by the drainage water flow to wash away the impurities on it, so the drainage water flow and the flushing water flow at the filter section position both intersect with the filter section. Or if it is other types of filtering structures, it is also necessary for the drainage water flow and the flushing water flow to flow through the filter section position.

[0173] More preferably, the filtration cross section is arranged parallel to the top wall 51 of the lifting shell 50, which has a through hole on the lifting shell 50. Since the through hole is arranged on the top wall 51 of the lifting shell 50 for water to enter, the filtration cross section is arranged parallel to the top wall 51, so that the water flow entering through the through hole on the top wall 51 is perpendicular to the filtration cross section. Moreover, whether it is the above-mentioned flushing water flow or drainage water flow, both enter the inner cavity through the through hole. The filtration cross section is arranged at a position parallel to the top wall 51 where the through hole is arranged, so that the drainage water flow entering the inner cavity can more easily flush the filtration cross section, and the flushing water flow entering the inner cavity can be filtered. The filtration cross section is projected onto 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 through the through hole on the top wall 51 can flow toward the filtration cross section. That is, the filter screen needs to be arranged parallel to the top wall 51 so that the drainage water flowing in from the through hole of the top wall 51 can flow directly to the filter screen, thereby achieving the effect of filtering the flushing water through the filter screen and flushing the filter screen with the drainage water.

[0174] More preferably, the filtration section is set in the filter cavity 502 at a position close to the top wall 51. Since the water inlet through hole is set on the top wall 51, the filtration section is set close to the top wall 51, that is, the filtration section is close to the water inlet through hole. The water flow entering the inner cavity is definitely larger the closer to the water inlet. Therefore, setting the filtration section close to the water inlet through hole can make the filtration section receive a larger water flow to flush, thereby facilitating the cleaning of impurities such as lint remaining on the filter structure. In addition, the water flow rate at the through hole position is the largest. Setting the filtration section on the top wall 51 close to the through hole can allow the filtration section to enter a larger amount of water flow in the inner cavity for filtration, thereby achieving a better filtration effect.

[0175] Specifically, a second baffle 612 is provided within the clothing lifting device to guide the flow of drain and wash water. The top wall 51 of the lifting housing 50, which is provided with a through hole, and the inner wall of the inner drum 4 form a filter chamber 502. The filter chamber 502 covers at least a portion of the through hole on the top wall 51, and the filter structure is disposed within the filter chamber 502. Specifically, the filter chamber 502 connects the through hole in the lifting housing 50 with the drain port 401 on the inner wall of the inner drum 4, draining water from the inner drum. Furthermore, the filter structure is disposed within the filter chamber 502. This allows water in the washing machine's inner drum to flow through the filter chamber 502, thereby cleaning the filter structure within the filter chamber 502. The position and structure of the clothing lifting device on the inner wall of the inner drum 4 of this embodiment are reasonably set, so that a filter chamber 502 for guiding the above-mentioned drainage water flow and flushing water flow can be formed in the inner cavity of the clothing lifting device, so that the flushing water flow can flow through the filter structure under the guidance of the filter chamber 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 chamber 502. In this way, the drainage water flow in the inner drum can be used to automatically clean the filter structure.

[0176] 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 it should be ensured that the filter cavity 502 has sufficient water flow when draining. Therefore, a partition structure can be set in the inner cavity of the clothing lifting device. The partition structure can surround the filter cavity 502, so that the filter cavity 502 with the partition structure can make the drainage flow along the set trajectory. As shown in Figure 1, Figure 2 、 Figure 6 As shown, the top wall 51 is connected to a second baffle 612 and a third baffle 613 that enclose the filter chamber 502. 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 baffle-type guiding structures. Through the limitation of the second baffle 612 and the third baffle 613, the drainage water flow and the flushing water flow can only flow within the range between the second baffle 612 and the third baffle 613, avoiding the drainage water flow from flowing too wide, causing the drainage water flow to diverge too much, resulting in insufficient impact force of the drainage water flow, and affecting the cleaning effect of the filter structure.

[0177] Since the drain outlet 401 is located outside the second baffle 612, the second baffle 612, the top wall 51, and the inner wall of the inner tube 4 cannot form the aforementioned closed filter chamber 502, as this would prevent the drainage water from flowing into the drain outlet 401. Therefore, at least an opening 5022 must be provided in the filter chamber 502 to allow the drainage water to flow into the drain outlet 401 through the opening 5022.

[0178] Specific as Figure 1 、 Figure 2As shown in FIG, a gap is defined between the end sidewall of the second baffle 612 near the drain outlet 401 and the inner wall of the inner cylinder 4. This gap forms an opening 5022 through which water in the inner cavity flows toward the drain outlet 401, allowing the drainage water to flow out through the opening 5022 and ultimately to be discharged through the drain outlet 401. Because the drainage water in the filter chamber 502 ultimately needs to flow toward the drain outlet 401 for discharge, a guide plate 5023 can be provided within the filter chamber 502 to guide the water toward the drain outlet 401. The provision of the guide plate 5023 facilitates the flow of water in the filter chamber 502 to converge toward the drain outlet 401, resulting in a larger flow toward the drain outlet 401. This allows the water, after cleaning the filter structure and containing debris such as lint, to flow toward the drain outlet 401 under the guidance of the guide plate 5023 and be discharged. Since the water flow after cleaning the filter structure contains debris such as lint that hinders the flow of water, the guide plate 5023 is provided to make the water flow more concentrated, thereby making the water flow to the drain outlet 401 larger, making it easier for the lint and the like to be discharged from the drain outlet 401.

[0179] Specific as Figures 1 to 3 、 Figure 5 As shown in , the guide plates 5023 are inclined structures that gradually tilt from the third baffle 613 toward the opening 5022 below the second baffle 612. This facilitates the drainage water flow along the inclined guide plates 5023 toward the drain outlet 401. Furthermore, the inclined structure of the guide plates 5023 increases the flow rate of the drainage water flow, further facilitating the removal of debris such as lint from the drainage water flow. Preferably, all guide plates 5023 form a conical surface with the cone tip pointing toward the drain outlet 401. The conical surface formed by the inclined guide plates 5023 gradually reduces the cross-sectional area of the water flow toward the drain outlet 401, thereby accelerating the flow rate of the water flow toward the drain outlet 401 and further facilitating the discharge of the water flow carrying lint from the drain outlet 401.

[0180] The clothing lifting device provided in this embodiment has a rational internal structure, enabling flushing water entering the clothing lifting device to be filtered by the filter structure. The drainage water then cleans the filter structure, flushing away impurities such as lint residue remaining on the filter structure and ensuring the filter structure's filtration effectiveness. In other words, the clothing lifting device provided by the present invention is self-cleaning, eliminating the need for manual cleaning of the filter structure. The filter structure can be self-cleaned by draining water from the inner drum 40.

[0181] 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 do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various changes and improvements made to the technical solutions of the present invention by professional and technical personnel in this field shall fall within the scope of protection of the present invention.
