[0061] Figure 1 The internal structure of a drum washing machine according to some embodiments is shown. Figure 1 , Figure 2 The internal structure of a drum washing machine according to some embodiments is shown. Figure 2 .

[0062] See also Figure 1 to Figure 2 A drum washing machine may include a housing (not shown in the figure). The housing is the external integral structure of the drum washing machine. The housing may be a hollow structure with an internal space, in which other component structures of the drum washing machine may be arranged, such as a circuit structure, an air duct structure, a driving mechanism, and a drainage structure.

[0063] In some embodiments, the box body may be provided in a rectangular parallelepiped shape or in a cylindrical shape, but is of course not limited to the above shapes.

[0064] In some embodiments, a clothing loading port may be opened on the housing, and the user may put clothing into the drum washing machine for washing through the clothing loading port.

[0065] In some embodiments, the box body may include a front panel (not shown in the figure). The front panel is formed with the clothing loading port, which can be selectively opened or closed. When opened, it is convenient to put the clothes to be washed therein, and when closed, it is convenient to take out the washed clothes to prevent dust and other impurities from entering the washing machine.

[0066] In some embodiments, the drum washing machine may include a washing drum. The washing drum may be arranged in the cabinet for washing clothes.

[0067] In some embodiments, the washing tub as a whole may be a cylindrical structure with an opening at one end and a washing chamber formed inside. The opening of the washing tub and the clothing loading port may be arranged opposite to each other to facilitate the loading of clothing into the washing tub through the clothing loading port.

[0068] In some embodiments, the washing tub may include an outer tub 10. The outer tub 10 may be disposed in the housing, and the outer tub 10, as a container for holding washing water, may be a cylindrical structure with one end open. A drain port may be provided at the bottom of the outer tub 10, through which the washing water after washing is discharged out of the housing.

[0069] In some embodiments, the washing drum may include an inner drum 20. The inner drum 20 is rotatably disposed in the outer drum 10, and the clothes finally enter the inner drum 20. The inner drum 20 may be a cylindrical structure with one end open. The clothes in the inner drum 20 are repeatedly raised and lowered by the rotation of the inner drum 20, so that the clothes are beaten to remove the stains in the clothes, and are used for washing the clothes.

[0070] In some embodiments, a plurality of water holes may be formed on the peripheral wall of the inner drum 20 , and wash water can enter the inner drum 20 from the outer drum 10 , or enter the outer drum 10 from the inner drum 20 , through the plurality of water holes.

[0071] In some embodiments, a mounting hole 200 may be opened on the peripheral wall of the inner cylinder 20 , and the shape of the mounting hole 200 may be circular or rectangular, which is not limited here.

[0072] In some embodiments, the opening of the inner drum 20 may also be formed on the front surface thereof, and the opening may be directly opposite to the clothing loading port.

[0073] In some embodiments, there may be a certain gap between the outer drum 10 and the inner drum 20, and the gap forms a cavity. The cavity can be connected to the inside of the inner drum 20 through a water hole. After washing is completed, the washing water can be discharged into the cavity and discharged through the drain port of the outer drum 10.

[0074] In some embodiments, a water containing cavity for containing washing water may be provided between the inner bottom of the outer tub 10 and the outer bottom of the inner tub 20. The water containing cavity is a part of the cavity, which is communicated with the interior of the inner tub 20.

[0075] In some embodiments, the drum washing machine includes lifting ribs 30. The lifting ribs 30 can be arranged on the inner drum 20. By arranging the lifting ribs 30, when the inner drum 20 rotates, the clothes can be driven to tumble up and down, thereby rubbing the clothes, simulating manual washing of clothes, and enhancing the washing effect of the clothes.

[0076] In some embodiments, the lifting ribs 30 may protrude from the inner circumferential wall of the inner drum 20, so that when the inner drum 20 rotates, the clothes can be caught, so as to be brought up and then dropped, thereby repeatedly hitting the clothes.

[0077] In some embodiments, the lifting ribs 30 may extend along the axial direction of the inner drum 20, and the overall layer is in a long strip shape, so that the clothes can be better rolled up when the inner drum 20 rotates. The lifting ribs 30 may be hollow inside, thereby reducing costs.

[0078] In some embodiments, friction patterns may be provided on the lifting ribs 30, so that the friction effect is stronger when in contact with clothing, and the ability to drive clothing is higher.

[0079] Figure 3 The internal structure of a drum washing machine according to some embodiments is shown. Figure 3 , Figure 4 Shows Figure 3 Sectional view along the AA direction, Figure 5 An example is shown Figure 4 A partial enlarged view of point B in the middle.

[0080] Continue to see Figures 3 to 5 In some embodiments, a screw hole may be provided on the lifting rib 30. The position of the screw hole corresponds to the position of the mounting hole 200 on the inner drum 20. When fixing the lifting rib 30, the lifting rib 30 may be fixed to the inner circumferential wall of the inner drum 20 by passing the screw 320 through the mounting hole 200 and the screw hole, so that the lifting rib 30 can rotate with the inner drum 20, driving the clothes to flip up and down.

[0081] In some embodiments, the lifting rib 30 and the inner cylinder 20 are connected by screws 320, and the connection method is simple and firm, and the lifting rib 30 is not easy to loosen.

[0082] In some embodiments, a fixing column 300 extending toward the inner wall of the inner drum 20 may be provided inside the lifting rib 30, and a screw hole is provided on the fixing column 300. By providing the fixing column 300, the length of the screw hole can be increased, so that the connection between the screw 320 and the lifting rib 30 is more stable. The fixing column 300 is provided inside the lifting rib 30, and the ability of the outer periphery of the lifting rib 30 to lift clothes will not be affected.

[0083] In some embodiments, the screw 320 may include a rod and a head connected to one end of the rod. The rod of the screw 320 is screwed into the screw hole to fix the lifting rib 30 and the inner cylinder 20. The head of the screw 320 is located outside the mounting hole 200, so that the head of the screw 320 abuts against the outer circumferential wall of the inner cylinder 20 to cooperate with the inner circumferential wall of the inner cylinder 20 to limit the radial movement of the lifting rib 30.

[0084] In some embodiments, the head of the screw 320 may be provided with a cross groove or a slotted groove, so that the screw 320 may be a cross screw 320 or a countersunk screw 320 for easy insertion.

[0085] Figure 6 The schematic diagram of the structure of the inner drum of a drum washing machine according to some embodiments is exemplarily shown. Figure 7 An example is shown Figure 6 A partial enlarged view of point C in the middle. Figure 8 The schematic structural diagram of the lifting ribs of the drum washing machine according to some embodiments is exemplarily shown.

[0086] Continue to see Figures 6 to 8 In some embodiments, a buckle 310 may be provided inside the lifting rib 30. The position of the buckle 310 is spaced from the position of the fixing column 300. A buckle position 210 may be provided on the inner circumferential wall of the inner cylinder 20 at a position corresponding to the position 210 of the buckle 310, and the lifting rib 30 may be buckled with the inner circumferential wall of the inner cylinder 20 by the buckle 310 in the buckle position 210, so that the lifting rib 30 and the inner cylinder 20 are fixed more firmly in cooperation with the screw 320.

[0087] In some embodiments, a plurality of buckles 310 and screw holes may be provided and distributed at different locations of the lifting rib 30 , thereby enhancing the connection stability between the lifting rib 30 and the inner cylinder 20 .

[0088] In some embodiments, the buckle position 210 may be a clamping hole, and the buckle 310 is buckled into the clamping hole, thereby connecting the lifting rib 30 and the inner tube 20 .

[0089] In some embodiments, the clamping hole may include a first hole segment and a second hole segment along the axial direction of the inner cylinder 20. The first hole segment and the second hole segment are connected, and the first hole segment and the second hole segment may be rectangular holes. The widths of the first hole segment and the second hole segment are different, and the width of the first hole segment may be greater than the width of the second hole segment. The first hole segment is closer to the opening end of the inner cylinder 20 relative to the second hole segment.

[0090] In some embodiments, when installing the lifting rib 30, the lifting rib 30 can be pushed from the outside of the inner tube 20 to the bottom of the inner tube 20, so that the buckle 310 first passes through the first hole section to facilitate the buckle 310 to pass through, and finally buckles on the second hole section to facilitate the installation and removal of the lifting rib 30.

[0091] In this embodiment, a disassembly hole 100 may be provided on the outer drum 10, and the disassembly hole 100 may be a circular hole or a rectangular hole. A removable plugging cover 40 is provided on the disassembly hole 100, and the plugging cover 40 is used to block the disassembly hole 100. When the plugging cover 40 is removed, it is convenient to operate the screw 320, and after the lifting rib 30 is installed, the disassembly hole 100 is blocked by the plugging cover 40 to prevent the washing water from leaking from the disassembly hole 100 to the outside of the outer drum 10 and damaging the parts in the box.

[0092] In some embodiments, the disassembly hole 100 is configured as follows: in the radial direction of the inner cylinder 20, the mounting hole 200 can be rotated to be opposite to the position of the disassembly hole 100, and the disassembly hole 100 is used for the disassembly tool to be inserted to install and remove the screw 320. In this way, when it is necessary to disassemble the lifting rib 30, the mounting hole 200 is rotated to be opposite to the disassembly hole 100, and the screw 320 is removed by the disassembly tool, so that the lifting rib 30 can be disassembled without disassembling the outer cylinder 10, and the installation is similar, thereby greatly improving the convenience of installation and removal of the lifting rib 30, saving maintenance time, and reducing maintenance costs.

[0093] In some embodiments, the disassembly tool may be a screwdriver matching the screw 320 , or may be any tool that can rotate the head of the screw 320 .

[0094] Fig. 9 The schematic structural diagram of the blocking cover of the drum washing machine according to some embodiments is exemplarily shown.

[0095] See also Fig. 9 In some embodiments, the plugging cover 40 may include a cover body 400. The cover body 400 may be in a flat plate shape, and the cover body 400 abuts against the outer peripheral wall of the outer cylinder 10. The cover body 400 may cover the disassembly hole 100, so that the cover body 400 may block the disassembly hole 100.

[0096] In some embodiments, the plugging cover 40 may include a plug 410. The plug 410 is connected to one end of the cover body 400 facing the outer peripheral wall of the outer cylinder 10, so that the plugging cover 40 may be stepped as a whole.

[0097] In some embodiments, the plug 410 can be inserted into the disassembly hole 100, and the peripheral side of the plug 410 is sealed and connected to the inner wall of the disassembly hole 100. The plug 410 can be used to clamp the plug cover 40 into the disassembly hole 100, such as the plug 410 and the disassembly hole 100 are transitionally matched, and the size of the two is used to clamp the plug 410. Through the arrangement of the plug 410 and the cover body 400, the plug cover 40 seals the disassembly hole 100, and when it is necessary to disassemble, the plug cover 40 can be pulled out.

[0098] In some embodiments, a handle piece can be provided on the end surface of the cover body 400 facing away from the plug 410. The handle piece can be provided to facilitate the operator to pull out the plug 40 by simply pulling the handle piece when it is necessary to pull out the plug 40.

[0099] In some embodiments, the handle piece can be a handle groove opened on the end surface of the cover body 400 facing away from the plug 410. The plug cover 40 can be directly lifted through the handle groove, which is convenient and quick to operate.

[0100] In some embodiments, the handle member may also be a pull rope provided on an end surface of the cover body 400 facing away from the plug 410, and the plug cover 40 can be directly pulled out by the pull rope.

[0101] In some embodiments, a limiting ring plate 110 may be provided on the outer peripheral wall of the outer cylinder 10, and the limiting ring plate 110 protrudes from the outer peripheral wall of the outer cylinder 10 to form a ring-blocking structure. The disassembly hole 100 is located in the limiting ring plate 110, and the peripheral side of the cover body 400 can abut against the inner wall of the ring plate. The limiting ring plate 110 is used to clamp the cover body 400, and the plug 410 is used to clamp the plug cover 40 on the outer cylinder 10.

[0102] In some embodiments, when the mounting hole 200 rotates with the inner cylinder 20 to be opposite to the disassembly hole 100 , the mounting hole 200 and the disassembly hole 100 are coaxially arranged, which facilitates the disassembly tool to align the head of the screw 320 to disassemble the screw 320 .

[0103] In some embodiments, the diameter of the disassembly hole 100 may be larger than the diameter of the installation hole 200, so as to facilitate the operation of the disassembly tool and make the disassembly easier for the operator.

[0104] In some embodiments, the outer wall of the inner cylinder 20 can be partially recessed toward the lifting rib 30 to form a recess 220, and the mounting hole 200 is opened on the bottom surface of the recess 220, so that the recess 220 can be used to position the disassembly and assembly auxiliary tool, and the disassembly and assembly auxiliary tool can be extended into the recess 220.

[0105] The present application also provides a disassembly and assembly auxiliary tool, which is used in a drum washing machine to assist an operator in using the disassembly tool to install and remove the screws 320, making the installation and removal of the screws 320 more convenient.

[0106] Fig.10 The schematic diagram of the structure of the disassembly and assembly auxiliary tool according to some embodiments is exemplified.

[0107] See also Fig.10In some embodiments, the disassembly and assembly auxiliary tool may include a barrel 50. The barrel 50 is arranged to penetrate, and a hollow passage is formed inside the barrel 50. The barrel 50 is used to extend into the disassembly hole 100, and the outer diameter of the barrel 50 is less than or equal to the hole diameter of the disassembly hole 100. When the screw 320 needs to be installed or removed, the barrel 50 is inserted into the disassembly hole 100, one end of the barrel 50 is aligned with the installation hole 200, and the disassembly tool is inserted from the inside of the barrel 50 to install or remove the screw 320.

[0108] In some embodiments, a fracture 500 is formed on the peripheral wall of the cylinder 50 along its axial direction, and the fracture 500 extends to one end of the cylinder 50 in the axial direction to form a clamping end 510. By providing the fracture 500, the cylinder 50 has a certain amount of deformation. When the cylinder 50 is inserted into the disassembly hole 100, the disassembly tool rotates the screw 320 outward, and then uses the clamping end 510 to clamp the screw 320, thereby preventing the screw 320 from falling into the space between the inner cylinder 20 and the outer cylinder 10 during the disassembly process, which increases the maintenance workload.

[0109] In some embodiments, the cylinder 50 can be made of plastic material, so that after the fracture 500 is set, it has a large plastic deformation, which makes it convenient for the operator to clamp the end of the cylinder 50 outside the outer cylinder 10 to deform and shrink the clamping end 510 of the cylinder 50, thereby clamping the head of the screw 320.

[0110] In some embodiments, the edge of the clamping end 510 of the barrel 50 can extend toward the axis direction of the barrel 50 to form a support ring plate 520, and the support ring plate 520 can be in the shape of a flat plate. The fracture 500 extends to the support ring plate 520. When the clamping end 510 shrinks and deforms, the support ring plate 520 shrinks inward, thereby clamping the head of the screw 320. When clamping, the support ring plate 520 can extend into the bottom wall of the head of the screw 320, and the support ring plate 520 abuts against the bottom wall of the head of the screw 320. When the disassembly hole 100 is extended outward, the clamping end 510 of the barrel 50 clamps the head of the screw 320, and the support ring plate 520 supports the bottom wall of the head of the screw 320, further ensuring that the screw 320 will not fall off.

[0111] In some embodiments, the inner diameter of the support ring plate 520 may be larger than the head diameter of the screw 320 , so that when the clamping end 510 is deformed, the support ring plate 520 may shrink and abut against the bottom wall of the head of the screw 320 to clamp the screw 320 .

[0112] In some embodiments, the peripheral wall of the cylinder 50 may be provided with two of the above-mentioned fractures 500 at intervals along its circumferential direction. Providing the two fractures 500 can make the deformation space of the cylinder 50 larger. When the operator pinches the cylinder 50, the clamping end 510 is more easily deformed and the screw head is clamped tighter.

[0113] In some embodiments, the two breaks 500 may be arranged opposite to each other, and the longer the break 500 extends in the axial direction of the cylinder 50 , the larger the deformation space of the cylinder 50 .

[0114] In some embodiments, when the lifting rib 30 needs to be removed, the inner cylinder 20 can be first rotated until the mounting hole on the inner cylinder 20 and the removal hole 100 on the outer cylinder 10 are opposite, and then the cylinder body 50 is inserted into the removal hole 100, so that the clamping end 510 of the cylinder body 50 is clamped on the recessed portion 220 of the inner cylinder 20, and finally the screw is unscrewed by the disassembly tool, and the head of the screw 320 is clamped by the clamping end 510 of the cylinder body 50, so as to bring the screw 320 out of the removal hole 100, thereby completing the separation of the lifting rib 30 and the inner cylinder 20.
