The drum includes a cylinder body, a front flange fixedly connected to the front end of the cylinder body, and a rear flange fixedly connected to the rear end of the cylinder body. The front flange has a central opening, and the central opening serves as the drum opening so as to take in and out clothes from the inner washing space of the cylinder body. A tripod is fixedly connected to the rear flange, and the tripod passes through the outer tub and is connected to the motor through a bearing and a pulley for transmission to realize the forward and reverse rotation of the tripod, and then drive the drum to rotate forward and backward;

[0003] For the existing drum washing machines, a clothes lifting part is provided on the inner surface of the cylinder wall of the cylinder body. Its main function is that when the drum washing machine washes clothes, on the one hand, it makes the clothes generate frictional force with it, and the part of the clothes close to the clothes lifting part rubs against the clothes lifting part to generate a rubbing effect; on the other hand, the clothes lifting part drives the clothes to rotate together, and the clothes are lifted out of the liquid surface and sent to a certain height, and then fall back into the washing liquid due to gravity, and collide with the washing liquid to generate a beating and falling effect, so as to achieve the washing effect. Since the clothes lifting part is only provided on the cylinder wall of the cylinder body, it can only rub and knead the clothes around the cylinder wall and lift the clothes around the cylinder wall to collide with the liquid surface, and cannot realize the rubbing and kneading of the clothes at the front end of the drum and the lifting of the clothes at the front end of the drum to collide with the liquid surface, reducing the washing effect on the clothes.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the technical problems in the prior art, and provide a drum assembly and a washing machine. By providing a clothes lifting part protruding into the drum on the annular end cover at the front end of the drum, the rubbing and kneading of the clothes at the front end of the drum and the lifting of the clothes at the front end of the drum to collide with the liquid surface are realized, so as to achieve the purpose of enhancing the washing effect on the clothes.

[0006] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

A clothes lifting part protruding into the drum is provided on the annular end cover.

[0008] Further, the clothing lifting part is in a strip structure, and the strip-shaped clothing lifting part extends along the circumferential direction of the annular end cover.

[0009] Further, the radial width of the clothing lifting part gradually decreases along the protruding direction of the clothing lifting part.

[0010] Further, a plurality of strip-shaped clothing lifting parts are provided on the annular end cover, and the distances between at least two strip-shaped clothing lifting parts and the drum opening are not equal;

[0011] Preferably, a plurality of clothing lifting parts are distributed in a circle along the circumferential direction of the annular end cover, and multiple circles are provided on the annular end cover;

[0012] Further preferably, the strip-shaped clothing lifting parts are alternately distributed in a concave-convex manner along the extending direction of the clothing lifting part.

[0013] Further, screws are provided on the annular end cover and penetrate the annular end cover in the direction of the drum, and the parts of the screws penetrating the annular end cover are partially hidden on the strip-shaped clothing lifting parts.

[0014] Further, grooves with openings facing the annular end cover are provided on the strip-shaped clothing lifting parts, and the strip-shaped clothing lifting parts are buckled on the annular end cover, and the parts of the screws penetrating the annular end cover are completely embedded in the grooves.

[0015] Further, a locking part for locking and cooperating with the part of the screw penetrating the annular end cover is provided in the groove of the strip-shaped clothing lifting part.

[0016] Further, the locking part includes a mounting seat completely embedded in the groove of the strip-shaped clothing lifting part. A locking hole is provided on the mounting seat, and the opening of the locking hole faces the annular end cover. The screw is inserted into the locking hole through the opening of the locking hole and is locked and cooperated with the locking hole.

[0017] Further, a sealing part is provided in the gap between the screw and the annular end cover and the groove.

Detailed implementation manners

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0032] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0033] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] As Figure 1 and Figure 2 shown, the present invention provides a drum assembly, which includes a drum 1. The front end of the drum 1 is constituted by an annular end cover 2. The outer circumference of the annular end cover 2 is connected to the drum wall of the drum 1, and the inner circumference encloses a drum opening 21. The annular end cover 2 is provided with a clothing lifting portion 3 protruding into the drum 1.

[0035] In an embodiment of the present invention, the front end of the drum 1 is provided with an opening. The drum 1 has an annular end cover 2 that covers a part of the opening at the opening. The outer circumference of the annular end cover 2 is connected to the drum wall of the drum 1, and the inner circumference of the annular end cover 2 encloses a drum opening 21. The drum opening 21 is a part of the opening;

[0036] The annular end cover 2 is provided with a laundry lifting part 3 protruding into the drum 1, which can generate frictional force with the laundry at the front end of the drum 1. The part of the laundry close to the laundry lifting part 3 rubs against the laundry lifting part 3 to produce a kneading effect, and the laundry lifting part 3 rotating with the drum 1 drives the laundry at the front end of the drum 1 to rotate together. The laundry is lifted out of the liquid level and sent to a certain height, and then falls back into the laundry detergent due to gravity, hitting the laundry detergent to produce the effects of beating and dropping, so as to realize the frictional kneading of the laundry at the front end of the drum 1 and the lifting of the laundry at the front end of the drum 1 to impact the liquid level, improving the washing effect of the laundry;

[0037] For this drum 1 assembly, not only is a laundry lifting part provided on the side wall of the drum 1, but also a laundry lifting part is provided on the annular end cover 2 at the front end of the drum 1, increasing the range of frictional kneading of the laundry and the probability of the laundry being lifted to a certain height.

[0038] Among them, the annular end cover 2 at the front end of the drum 1 can be an annular front flange 22. The outer periphery of the annular front flange 22 is connected to the drum 1, and the inner periphery encloses the drum opening 21. The laundry lifting part 3 is provided on the annular front flange 22 and protrudes into the drum 1 relative to the annular front flange 22, that is, the laundry lifting part 3 is provided on the side of the annular front flange 22 facing the inside of the drum 1, or the annular end cover 2 is a folded edge formed by bending the side wall of the drum.

[0039] The drum 1 can be a perforation-free inner drum, which is used for a drum washing machine and is used to hold washing water and laundry.

[0040] Such as Figure 2 and Figure 3 As shown, in the embodiment of the present invention, the laundry lifting part 3 is in a strip structure, and the strip laundry lifting part 31 extends along the circumferential direction of the annular end cover 2.

[0041] In the embodiment of the present invention, the laundry lifting part provided on the annular end cover 2 is in a strip structure. Specifically, the laundry lifting part is in a long strip structure, and the strip laundry lifting part 31 is provided on the annular end cover 2 along the circumferential direction of the annular end cover 2, that is, the strip laundry lifting part 31 extends along the rotation direction of the drum 1. Since the laundry and the strip laundry lifting part 31 rotate with the drum, the above-mentioned strip laundry lifting part 31 can extend the time of contact and friction with the laundry, and can increase the contact with the laundry to increase the probability of the laundry being lifted, preventing the laundry from falling before being lifted to a certain height;

[0042] The annular front flange 22 is in a stepped shape, including a first annular section and a second annular section arranged concentrically. The second annular section is located inside the first annular section. The outer periphery of the first annular section is connected to the drum 1, and the inner periphery of the second annular section forms the drum opening 21. The strip laundry lifting part 31 is provided on the side of the second annular section facing the drum 1 and extends on the second annular section along the circumferential direction of the second annular section.

[0043] The annular end cap 2 is circular-ring-shaped. Therefore, the strip-shaped garment lifting part 31 extending circumferentially along the annular end cap 2 is arc-shaped.

[0044] As Figure 3 shown, in the embodiment of the present invention, the radial width of the garment lifting part 3 gradually decreases along the protruding direction of the garment lifting part.

[0045] In the embodiment of the present invention, the strip-shaped garment lifting part 31 protrudes into the drum 1 on the annular end cap 2. The radial width of the strip-shaped garment lifting part 31 gradually decreases along the protruding direction of the garment lifting part. That is to say, the strip-shaped garment lifting part 31 has an inclined surface along its own protruding direction and inclines towards the inside of the drum 1, so that after the strip-shaped garment lifting part 31 lifts the garment, the garment can fall down along the inclined surface of the strip-shaped garment lifting part 31, reducing the blockage of the garment falling.

[0046] As Figure 6 shown, in the embodiment of the present invention, the strip-shaped garment lifting part 31 is hollow inside to form a groove 311, and the opening 312 of the groove is formed at the large-size end of the strip-shaped garment lifting part 31 in the protruding direction of the garment lifting part and faces the annular end cap 2.

[0047] In the embodiment of the present invention, the strip-shaped garment lifting part 31 is hollow inside. On the one hand, it reduces the weight of the strip-shaped garment lifting part 31. On the other hand, it reduces the material for making the strip-shaped garment lifting part 31, saving costs;

[0048] The groove 311 has an opening. The opening 312 of the groove is arranged at the large-size end of the strip-shaped garment lifting part 31 in the protruding direction of the garment lifting part. The opening 312 of the groove faces the annular end cap 2, and the annular end cap 2 closes the opening 312 of the groove, which is equivalent to the annular end cap 2 buckling on the strip-shaped garment lifting part 31;

[0049] Specifically, the cross-section of the strip-shaped garment lifting part 31 along the circumferential direction of the annular end cap 2 is triangular. The strip-shaped garment lifting part 31 includes a first wall and a second wall protruding into the drum 1. The first wall and the second wall are smoothly transitioned. That is to say, there is a connecting surface between the first wall and the second wall, and the connecting surface is an arc surface protruding towards the inside of the drum 1, reducing the excessive frictional damage to the garment. The first wall and the second wall are also arc walls, aiming to reduce the excessive frictional damage to the garment.

[0050] Among them, the material used for the strip-shaped garment lifting part 31 is plastic. Since the strip-shaped garment lifting part 31 extends into the drum 1 and rubs against the garment, therefore, using plastic as the material for the strip-shaped garment lifting part 31 can avoid rusting when encountering water by itself and reduce the pollution to the garment and the washing water.

[0051] Specifically, several strip-shaped clothing lifting portions 31 are provided on the annular end cover 2, and the distances between at least two strip-shaped clothing lifting portions 31 and the drum opening 21 are not equal, all for increasing the contact area with the clothing; several strip-shaped clothing lifting portions 31 are distributed in a circle along the circumferential direction of the annular end cover, and multiple circles are provided on the annular end cover 2.

[0052] Further specifically, the strip-shaped clothing lifting portions 31 are alternately concave and convex along the extending direction of the lifting portions, increasing the friction force with the clothing.

[0053] As Figure 4 、 Figure 5 and Figure 6 shown, in the embodiment of the present invention, screws 23 for fixing components on the annular end cover 2 are provided on the annular end cover 2. The screws 23 sequentially pass through the components and the annular end cover 2 and extend into the drum 1. A locking member 4 that is in locking cooperation with the screw 23 is provided in the groove 311 of the strip-shaped clothing lifting portion 31.

[0054] In the embodiment of the present invention, a door hinge 6 is provided on the annular end cover 2. The door hinge 6 is a component fixed on the annular end cover 2. The annular end cover 2 is hinged to the door body through the door hinge 6, enabling the door body to open or close the drum opening 21; the door hinge 6 is fixed on the annular end cover 2 through the screw 23. Specifically, the door hinge 6 includes a hinge seat 61 and a hinge. The hinge is provided on the hinge seat 61. The hinge seat 61 is strip-shaped. The strip-shaped hinge seat 61 extends along the circumferential direction of the annular end cover 2. The strip-shaped hinge seat 61 faces the strip-shaped clothing lifting portion 31. The length of the strip-shaped hinge seat 61 extending along the circumferential direction of the annular end cover 2 is equal to the length of the strip-shaped clothing lifting portion 31 extending along the circumferential direction of the annular end cover 2; the hinge seat 61 has two first fixing holes penetrating the hinge seat 61 along its own extending direction. Corresponding second fixing holes penetrating the annular end cover 2 are provided on the annular end cover 2. The screw 23 sequentially passes through the first fixing hole and the second fixing hole to penetrate the hinge seat 61 and the annular end cover 2 and extends into the drum 1 to be connected and fixed to the locking member 4. The locking member 4 is located inside the drum.

[0055] Screws that penetrate the annular end cover 2 in the direction towards the inside of the drum are provided on the annular end cover 2. The part of the screw penetrating the annular end cover 2 is hidden on the strip-shaped clothing lifting portion 31. The screw 23 is in locking cooperation with the locking member 4 provided in the groove 311 of the strip-shaped clothing lifting portion 31. If the locking member 4 is made of metal, then the strip-shaped clothing lifting portion made of plastic can seal the screw 23 and the locking member 4, preventing the screw 23 and the locking member 4 from contacting water and being corroded. Of course, the locking member 4 can also be a non-metallic part, as long as it can be in locking cooperation with the screw 23 to fix the door hinge 6 on the annular end cover 2.

[0056] As Figure 4 、 Figure 5 and Figure 6As shown in the figure, in the embodiment of the present invention, the locking member 4 includes a mounting seat 41 disposed in the groove 311 of the strip-shaped clothing lifting portion 31. A locking hole 411 is provided on the mounting seat 41. The opening 412 of the locking hole 411 faces the same direction as the opening 312 of the groove. The screw 23 is inserted into the locking hole 411 through the opening 412 of the locking hole and is in locking cooperation with the locking hole 411.

[0057] In the embodiment of the present invention, specifically, the locking member 4 includes a mounting seat 41. The mounting seat 41 is disposed in the groove 311 of the strip-shaped clothing lifting portion 31. A locking hole 411 is provided on the mounting seat 41. The opening 412 of the locking hole faces the same direction as the opening 312 of the groove, that is, the opening 412 of the locking hole faces the annular end cover 2. The annular end cover 2 seals the opening 412 of the locking hole. The mounting seat 41 is completely embedded in the groove 311. In order to achieve the locking between the screw 23 and the locking hole 411, the radial dimension of the screw 23 is slightly larger than the radial dimension of the locking hole 411. The screw 23 is tightly inserted into the locking hole 411 through the opening 412 of the locking hole. Among them, the thread on the rod portion of the screw 23 can increase the friction force between the screw 23 and the locking hole 411, and further increase the locking force between the two.

[0058] The material of the mounting seat 41 can be plastic, and the mounting seat 41 and the strip-shaped clothing lifting portion 31 are integrally formed.

[0059] As Figure 4 、 Figure 5 and Figure 6 As shown in the figure, in the embodiment of the present invention, a seal 5 for sealing the gap between the locking hole 411 and the screw 23 is provided in the locking hole 411.

[0060] In the embodiment of the present invention, in order to prevent water from entering the gap between the locking hole 411 and the screw 23 and causing the screw 23 to be corroded and rusted, a seal 5 is provided in the gap between the locking hole 411 and the screw 23;

[0061] Specifically, the seal 5 includes a seal seat 51. At least part of the seal seat 51 is embedded in the locking hole 411. A receiving hole 511 is provided on the seal seat 51. The opening 512 of the receiving hole faces the same direction as the opening 312 of the groove. The screw 23 is inserted into the receiving hole 511 through the opening 512 of the receiving hole and cooperates with the mounting seat 41 to clamp the seal seat 51 tightly; the seal 5 includes a seal seat 51. At least part of the seal seat 51 is embedded in the locking hole 411. The seal seat 51 exposed outside the locking hole 411 can be in contact with the annular end cover 2, which can further prevent water from entering the gap between the locking hole 411 and the screw 23; a receiving hole 511 is provided on the seal seat 51. The opening 512 of the receiving hole faces the annular end cover 2. The annular end cover 2 covers the opening 512 of the receiving hole. The screw 23 is tightly inserted into the receiving hole 511 through the opening 512 of the receiving hole, so that the seal seat 51 is tightly clamped in the gap between the screw 23 and the locking hole 411.

[0062] As Figure 5 shown, in the embodiment of the present invention, a through hole is provided on the annular end cover 2. At least part of the seal seat 51 passes through the through hole of the annular end cover 2 and is in contact with the component.

[0063] In the embodiment of the present invention, the seal seat 51 includes a first part embedded in the locking hole 411 and a second part exposed outside the locking hole 411. The seal seat 51 is cylindrical. The first part and the second part are coaxially arranged. The radial dimension of the second part is smaller than that of the first part. The second part passes through the through hole of the annular end cover 2 and is in contact with the component, which increases the sealing performance between the annular end cover 2 and the door hinge 6 and further prevents water from entering the gap between the screw 23 and the locking hole 411.

[0064] As Figure 6 shown, in the embodiment of the present invention, a radially protruding insertion protrusion 513 is provided on the outer wall of the seal seat 51, and an insertion groove 413 for inserting the insertion protrusion 513 is provided on the inner wall of the mounting seat 41.

[0065] In the embodiment of the present invention, in order to enhance the installation strength of the seal seat 51 on the mounting seat 41 and avoid the decrease in sealing performance caused by the misalignment of the seal seat 51, therefore, the seal seat 51 is positioned on the mounting seat 41 by means of insertion;

[0066] Specifically, a radially protruding insertion protrusion 513 is provided on the outer wall of the seal seat 51, and an insertion groove 413 is provided on the inner wall of the mounting seat 41. The insertion protrusion 513 is inserted into the insertion groove 413; the insertion protrusion 513 extends along the axial direction of the seal seat 51, increasing the insertion length of the insertion protrusion 513, thereby increasing the insertion strength between the insertion protrusion 513 and the insertion groove 413.

[0067] The above are only the preferred embodiments of the present invention, and there is no limitation to the present invention in any form. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, may make some changes or modifications using the technical content prompted above into equivalent embodiments of equivalent changes.
