The inner drum is arranged inside the outer drum, and the bottom of the inner drum is movably connected to the output shaft of the motor. The clutch bracket is arranged inside the inner drum and moves along the output shaft of the motor and is used to engage with the bottom of the inner drum. The pulsator is arranged inside the inner drum and is connected to the output shaft of the motor, and the pulsator is connected to the side of the clutch bracket away from the inner drum. Its beneficial effect is that the inner drum has water during washing, only the pulsator and the clutch bracket rotate, and there is no water between the inner and outer drums during dehydration. The pulsator is tightly held together with the inner drum through the clutch, realizing rotation and dehydration together, thereby eliminating the need for a small clutch at the bottom of the inner drum, greatly saving the internal space of the washing machine.

[0004] Obviously, in the prior art including the above-mentioned patent, there is a gap between the inner and outer drums of the washing machine, which is used for water separation for spin-drying function, so it is easy to be in a humid state for a long time and is not easy to clean, resulting in the breeding of bacteria. In order to spin-dry clothes, a plurality of openings are usually provided on the inner drum of the washing machine. These openings make the inner space of the inner drum communicate with the gap between the inner and outer drums, thereby causing the bacteria breeding between the inner and outer drums to flow back into the inner drum in large quantities during the subsequent washing process, causing secondary pollution to the clothes. Therefore, a full-automatic rotating drum mechanism and a full-automatic washing machine are needed to solve the above-mentioned problems. SUMMARY

[0005] The purpose of the present application is to provide a full-automatic rotating drum mechanism and a full-automatic washing machine to solve the above-mentioned deficiencies in the prior art.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the protection scope of the present disclosure.

[0038] Please refer to Figures 1-12The embodiment of the application provides a kind of full-automatic rotary drum mechanism, including first cylinder 1, first cylinder 1 is rotationally arranged with second cylinder 2, second cylinder 2 is rotationally arranged with wave wheel 3, the inner wall of second cylinder 2 is provided with multiple first through holes 4, further comprising: multiple flaps 5, which are movably arranged on the outer wall of second cylinder 2, and multiple second through holes 6 are arranged thereon;Driving assembly has the first state of driving wave wheel 3 to rotate alone and the second state of driving second cylinder 2 and wave wheel 3 to rotate synchronously;In the first state of driving assembly, flap 5 drives second through hole 6 to be staggered with first through hole 4;In the second state of driving assembly, flap 5 drives second through hole 6 to be communicated with first through hole 4.

[0039] Specifically, the first cylinder 1, i.e. the outer cylinder inside the washing machine, is approximately cylindrical in shape, with an open upper end and a closed other face; a horizontal partition is provided inside the first cylinder 1, which divides the first cylinder 1 into a washing space in the upper part and a driving space in the lower part, and a ring-shaped convex body is provided on the upper end of the partition; the second cylinder 2 is supported on the convex body at the lower end, and a rotating ring is coaxially arranged and embedded in the convex body; the rotating ring is hooked on the convex body and is sealingly connected in rotation with the convex body, so that the washing space and the driving space are isolated from each other and water is prevented from entering the driving space. The second cylinder 2, i.e. the inner cylinder inside the washing machine, is approximately cylindrical in shape, with an open upper end and a rough inner wall to increase friction with clothes during washing and improve washing effect; the outer diameter of the second cylinder 2 is smaller than the inner diameter of the first cylinder 1, so that a gap is formed between the outer wall of the second cylinder 2 and the inner wall of the first cylinder 1, which is used for water separation during clothes drying in the washing machine; the lower end of the second cylinder 2 is in the shape of a circular truncated cone with a continuously decreasing outer diameter. The impeller 3 is arranged against the inner bottom surface of the second cylinder 2 and is used to stir water inside the second cylinder 2 during washing. The first through holes 4 are usually arranged vertically on the inner wall of the second cylinder 2, and a plurality of vertical first through holes 4 form a group; a plurality of groups of first through holes 4 are arranged circumferentially on the inner wall of the second cylinder 2; the first through holes 4 are used for draining water during clothes drying and for assisting in draining water after washing in the second cylinder 2. The flap 5 is arranged against the outer surface of the second cylinder 2, and when the second through hole 6 does not correspond to the first through hole 4, the flap 5 blocks the first through hole 4 so that the first through hole 4 cannot communicate with the outside; the second through hole 6 corresponds to the first through hole 4 one by one, and is driven by the flap 5 to realize communication or misalignment with the first through hole 4. The first state of the driving assembly refers to that the second cylinder 2 and the impeller 3 are not rotationally linked, and the driving assembly only drives the impeller 3 to rotate; at this time, the impeller 3 stirs water and clothes in the second cylinder 2 to perform a washing function; further, under the control of the servo system of the washing machine, the driving assembly drives the impeller 3 to reciprocate at a low speed, which can better clean the clothes; the second state of the driving assembly refers to that the second cylinder 2 and the impeller 3 are rotationally linked, and the driving assembly drives the second cylinder 2 and the impeller 3 to rotate synchronously; at this time, under the control of the servo system of the washing machine, the driving assembly drives the second cylinder 2 and the impeller 3 to rotate rapidly in one direction, which can generate a large centrifugal force on the clothes in the second cylinder 2 to remove water from the clothes.

[0040] In actual use, the driving assembly is first in the first state, the second through hole 6 is driven by the flap 5 to be misaligned and separated from the first through hole 4, so that the gap between the second cylinder 2 and the first cylinder 1 and the second cylinder 2 is isolated, then clothes, water, laundry detergent or washing powder are added into the second cylinder 2, the driving assembly in the first state is started by the washing machine servo system to drive the impeller 3 to rotate alone and reciprocate at low speed, so that the water and clothes in the second cylinder 2 are fully stirred, and the washing function is realized. In the washing process, the gap between the second cylinder 2 and the first cylinder 1 and the second cylinder 2 is isolated, so that the backflow of bacteria caused by the water flow between the first cylinder 1 and the second cylinder 2 is avoided, and the clothes in the second cylinder 2 are prevented from being secondarily polluted in the washing process. Then, after the washing function is completed, the impeller 3 stops rotating, the second cylinder 2 naturally drains water outward, and after the natural drainage is completed, the driving assembly is switched from the first state to the second state, and the second through hole 6 is also driven by the flap 5 to be in one-to-one correspondence with the first through hole 4. At this time, the driving assembly in the second state is started by the washing machine servo system to drive the second cylinder 2 and the impeller 3 to synchronously rotate in one direction at a high speed, so that a large centrifugal force is generated on the clothes in the second cylinder 2, thereby the water in the clothes is thrown out and enters the gap between the first cylinder 1 and the second cylinder 2 through the first through hole 4 and the second through hole 6, and the clothes are realized.

[0041] Compared with the prior art, the full-automatic drum mechanism provided by the embodiment of the application is provided with the flap 5, when the driving assembly alone drives the impeller 3 to rotate in the first state, the washing function is realized, at this time, the second through hole 6 is misaligned with the first through hole 4 by the flap 5, so that the gap between the second cylinder 2 and the first cylinder 1 and the second cylinder 2 is isolated, thereby preventing the bacteria breeding in the gap between the first cylinder 1 and the second cylinder 2 from causing secondary pollution to the clothes in the second cylinder 2 by the water flow in the washing process. In addition, when the driving assembly is in the second state, the second through hole 6 is in correspondence with the first through hole 4 by the flap 5, so that the second cylinder 2 can rotate to dry the clothes.

[0042] As a preferred technical solution of the embodiment, a plurality of lifting grooves 7 matched with the flap 5 are arranged on the outer wall of the second cylinder 2, specifically, the lifting grooves 7 are arranged parallel to the axis of the second cylinder 2, the lifting grooves 7 are in one-to-one correspondence with the flap 5, preferably 5-10 in number, and are arranged equidistantly on the outer wall of the second cylinder 2; the second through hole 6 is in correspondence with the first through hole 4 in the horizontal direction, and is driven by the flap 5 in the lifting groove 7 to realize the adjustment of the vertical height difference between the second through hole 6 and the first through hole 4, so as to realize the corresponding communication or misaligned separation of the second through hole 6 and the first through hole 4.

[0043] As a further preferred technical solution of the embodiment, a sealing groove 8 is arranged on the inner side of the lifting groove 7, and a sealing strip 9 is fixedly arranged on the flap 5 and movably connected with the sealing groove 8. Specifically, the sealing groove 8 covers all the first through holes 4, and the length of the sealing strip 9 is not less than that of the sealing groove 8. When the flap 5 is lifted in the lifting groove 7, the sealing strip 9 can keep sealing the gap between the flap 5 and the lifting groove 7.

[0044] As a preferred technical solution of the embodiment, the driving assembly comprises a rotating shaft 10 coaxially connected with the impeller 3, a linkage sleeve 11 sleeved on the rotating shaft 10, the linkage sleeve 11 being fixedly connected with the second cylinder 2 at the upper end, a lifting seat 12 synchronously rotatable being sleeved on the linkage sleeve 11, the lifting seat 12 being provided with a first toothed disc 13 at the lower end, and the rotating shaft 10 being coaxially connected with a second toothed disc 14. Specifically, the first cylinder 1 is provided with a motor 27 at the bottom, the output end of the motor 27 is coaxially connected with the rotating shaft 10, the rotating shaft 10 is vertically arranged in a driving space in the first cylinder 1, and the rotating shaft 10 penetrates through the bottom of the second cylinder 2; the rotating shaft 10 is rotatably connected with the linkage sleeve 11 and is rotatably sealed; the outer wall of the linkage sleeve 11 is in the shape of a polygonal rod, the lifting seat 12 is provided with a through groove matching the shape of the polygonal rod and movably sleeved on the outer side of the linkage sleeve 11, so as to be axially movable relative to the linkage sleeve 11 and synchronously rotatable with the linkage sleeve 11; the second toothed disc 14 is arranged below the first toothed disc 13 and is provided with teeth on the end faces close to each other; when the first toothed disc 13 keeps away from the second toothed disc 14, i.e. the teeth are separated, the rotation of the rotating shaft 10 only drives the rotation of the impeller 3, i.e. corresponding to the first state of the driving assembly; when the first toothed disc 13 keeps engaged with the second toothed disc 14, i.e. the teeth are engaged, the rotation of the rotating shaft 10 not only directly drives the rotation of the impeller 3, but also drives the rotation of the second toothed disc 14 through the first toothed disc 13, and then drives the rotation of the linkage sleeve 11 through the lifting seat 12, so as to drive the rotation of the second cylinder 2, thereby realizing the synchronous rotation of the impeller 3 and the second cylinder 2, i.e. corresponding to the second state of the driving assembly.

[0045] As a further preferred technical solution of the embodiment, the lifting seat 12 is provided with a lifting plate 15, the upper end of the lifting plate 15 is connected with a lifting ring 17 through a connecting rod 16, the lower end of the plurality of flaps 5 is connected with the same rotating ring 18 which is rotatably connected with the lifting ring 17. Specifically, the lifting seat 12 is provided with a snap ring on the side opposite to the first toothed disc 13, and the snap ring and the first toothed disc 13 limit the upper and lower sides of the lifting plate 15 respectively, so that the lifting plate 15 is lifted synchronously with the lifting seat 12; the lifting plate 15 is lifted in the driving space in the first cylinder body 1; the lifting ring 17 is arranged in the washing space of the first cylinder body 1, the connecting rod 16 is movably and sealingly arranged through the partition plate in the first cylinder body 1; the lifting ring 17 is rotatably connected with the rotating ring 18, which can not only realize the lifting of the lifting ring 17 and the flaps 5, but also does not affect the subsequent rotation of the flaps 5 with the second cylinder body 2. The lifting of the lifting plate 15, on the one hand, drives the first toothed disc 13 to lift through the lifting seat 12, so as to control the meshing and separation of the first toothed disc 13 and the second toothed disc 14, that is, to control the switching between the first state and the second state of the driving assembly; on the other hand, the lifting ring 17 is lifted through the connecting rod 16, and the lifting ring 17 drives the flaps 5 to lift through the rotating ring 18, so that the flaps 5 drive the second through hole 6 to correspondingly communicate with the first through hole 4 and dislocate and separate; thereby realizing the linkage of the switching between the first state and the second state of the driving assembly and the communication or dislocation switching of the second through hole 6 and the first through hole 4, and the first state of the driving assembly corresponds to the dislocation and separation of the second through hole 6 and the first through hole 4, and the second state of the driving assembly corresponds to the corresponding communication of the second through hole 6 and the first through hole 4.

[0046] As a further preferred technical solution of the embodiment, the bottom of the first cylinder body 1 is provided with a lifter 19, the output end of the lifter 19 is connected with the lifting plate 15, specifically, the lifter 19 can be an existing device such as an electric lifting rod or a pneumatic lifting rod; the lifter 19 is arranged on the lower side of the first cylinder body 1 in a symmetrical or circumferentially symmetrical manner, and the output end of the lifter 19 is movably arranged through the first cylinder body 1; the lifting of the lifting plate 15 is actively driven by the lifter 19. The upper end of each flap 5 is connected with the same limiting ring 28, the upper end of the limiting ring 28 is provided with circumferentially arranged convex patterns, the upper end of the first cylinder body 1 is provided with an inwardly protruding retaining ring 29, the bottom surface of the retaining ring 29 is provided with a groove which is circumferentially arranged and matched with the convex patterns, in the first state of the driving assembly, the flaps 5 are lifted, the limiting ring 28 is lifted, and the upper end of the limiting ring 28 is inserted into the groove on the bottom surface of the retaining ring 29, thereby the rotation of the second cylinder body 2 can be limited, that is, when the driving assembly in the first state drives the pulsator 3 to rotate alone, it stirs the water and clothes in the second cylinder body 2, and does not drive the second cylinder body 2 to rotate, so as to ensure that the clothes in the second cylinder body 2 are fully rubbed with the inner wall thereof, and the washing effect is better realized.

[0047] In another embodiment of the present application, the lower end of the second cylinder 2 is provided with a drain port 20, and a gate assembly is arranged in the drain port 20. The opening and closing of the gate assembly is linked with the lifting of the flap 5. Specifically, the drain port 20 is provided with a plurality of drain ports corresponding to the positions of the flap 5, and the drain port 20 is arranged on the circular table-shaped slope at the bottom of the second cylinder 2. When the flap 5 is lifted, the gate assembly is closed, that is, in the first state of the driving assembly, the second through hole 6 is separated from the first through hole 4, and the gate assembly is closed to ensure the sealing of the second cylinder 2 and to facilitate the washing of clothes. When the flap 5 is lowered, the gate assembly is opened, that is, in the second state of the driving assembly, the second through hole 6 is in communication with the first through hole 4, and the gate assembly is opened to facilitate the natural drainage of the second cylinder 2 after washing clothes and to facilitate the drainage of the second cylinder 2 during the spinning of clothes. The gate assembly is linked with the lifting of the flap 5, and a separate driving unit is omitted to achieve passive opening and closing. The opening and closing of the gate assembly is just corresponding to the functional state of the second cylinder 2.

[0048] As a preferred technical solution of the present embodiment, the gate assembly includes a plurality of first gate rods 21 arranged in the drain port 20 at intervals. A rotating rod 22 is arranged in the drain port 20, and a plurality of second gate rods 23 are fixedly arranged on the rotating rod 22 and matched with the intervals of the first gate rods 21. Specifically, the first gate rods 21 are arranged obliquely and parallel to the generatrix of the circular table-shaped portion at the bottom of the second cylinder 2. The end of the first gate rod 21 is connected with the inner wall of the drain port 20 to form a wavy edge. The grooves on the wavy edge are matched with and correspond to the second gate rods 23. The interval between adjacent first gate rods 21 is the drainage interval. The rotating rod 22 is arranged at the upper end of the drain port 20 and above the first gate rods 21 and perpendicular to the first gate rods 21. The preferred number of the second gate rods 23 is matched with the number of the drainage intervals. The second gate rods 23 can be clamped above the drainage intervals through the rotation of the rotating rod 22, and the surface of the second gate rods 23 is tangent to the surface of the first gate rods 21. The two ends of the second gate rods 23 are clamped with the grooves of the wavy edge to block the drainage intervals. The second gate rods 23 can also move away from the drainage intervals upward through the rotation of the rotating rod 22 to open the drainage intervals for drainage. At the same time, the second gate rods 23 can push away the clothes that may block the drain port 20 to ensure the smoothness of the space near the drain port 20 and facilitate the drainage, thereby improving the overall efficiency of washing clothes. In addition, a rubber layer can be arranged on the outer surfaces of the first gate rods 21 and the second gate rods 23 to improve the sealing performance when the first gate rods 21 and the second gate rods 23 are closed.

[0049] As a further preferred technical solution of the embodiment, the rotating rod 22 is provided with a telescopic rod 24 penetrating therethrough, and the telescopic rod 24 is hingedly connected with a connecting piece 25, which is fixedly connected with the flap 5. Specifically, the second gate rod 23 is provided with a cavity, and one end of the telescopic rod 24 penetrates through the rotating rod 22 and is arranged in the cavity. The inner wall of the second cylinder 2 is provided with a movable groove for the connecting piece 25 to move. The connecting piece 25 moves up and down with the flap 5, and the end of the telescopic rod 24 moves up and down with the connecting piece 25, thereby driving the rotating rod 22 to rotate, and the rotating rod 22 drives the second gate rod 23 to rotate to close or open the drainage gap. During the rotation of the rotating rod 22, the telescopic rod 24 penetrates into or out of the cavity in the second gate rod 23 to adapt to the change of the position distance between the rotating rod 22 and the connecting piece 25. Since the connecting piece 25 moves up and down with the flap 5, the opening and closing of the drain port 20 are realized, and the switching of the first state and the second state of the driving assembly, the switching of the communication or misalignment of the second through hole 6 and the first through hole 4, and the switching of the opening and closing of the drain port 20 are all interlocked. In actual use, the driving assembly is first in the first state, the flap 5 is raised, the first through hole 4 is misaligned and separated from the second through hole 6, and the flap 5 also drives the end of the telescopic rod 24 to rise through the connecting piece 25, so that the rotating rod 22 drives the second gate rod 23 to rotate downward to close the drainage gap, thereby isolating the inside of the second cylinder 2 from the inside of the first cylinder 1. Then, the driving assembly in the first state can drive the impeller 3 to rotate to smoothly wash clothes, and no secondary pollution occurs during the washing process. After the washing is completed, the driving assembly is switched from the first state to the second state, the flap 5 is lowered, the first through hole 4 is close to the second through hole 6, and the flap 5 also drives the end of the telescopic rod 24 to lower through the connecting piece 25, so that the rotating rod 22 drives the second gate rod 23 to rotate upward to open the drainage gap, thereby allowing the second cylinder 2 to naturally drain water. After the drainage is completed, the driving assembly remains in the second state, the first through hole 4 is in communication with the second through hole 6, and the drain port 20 remains open. Then, the driving assembly in the second state can start to drive the second cylinder 2 and the impeller 3 to rotate synchronously to perform clothes spinning.

[0050] A full-automatic washing machine comprises the full-automatic rotating drum mechanism described above, and further comprises a machine body 26, and the first cylinder 1 is fixedly arranged in the machine body 26. Specifically, the machine body 26 is used for loading the first cylinder 1 and related components thereon, and plays a role of protection and aesthetic appearance. The machine body 26 is provided with a water inlet pipe 30 and a drain pipe 31, and both the water inlet pipe 30 and the drain pipe 31 have one end penetratingly extending to the outside of the machine body 26. The other end of the water inlet pipe 30 penetrates through the upper end of the side wall of the first cylinder 1 and is arranged higher than the second cylinder 2, so as to ensure that the water source is directly added into the second cylinder 2. The other end of the drain pipe 31 penetrates through the bottom of the first cylinder 1 and then penetrates through the partition plate in the first cylinder 1 to be communicated to the bottom surface of the washing space. The lifting plate 15 is provided with a through hole through which the drain pipe 31 penetrates, and the lifting plate 15 is not affected by the lifting movement.

[0051] The foregoing merely illustrates some exemplary embodiments of the application, and it will be appreciated that those skilled in the art will be able to devise various modifications without departing from the spirit and scope of the application. The appended drawings and description are illustrative only, and are not intended to be limiting.
