For the persons with ordinary skills in the art, the specific meaning of the above terms in the present disclosure can be understood based on the specific situation.

[0042] As shown in FIG. 1 to FIG. 5, the present disclosure provides a washing machine balancing ring, comprising a balancing ring body 2, wherein a ring-shaped rib 4 is arranged in the periphery of the balancing ring body 2, the balancing ring body 2 is connected to the ring-shaped rib 4, and multiple drainage holes 5 are disposed between the balancing ring body 2 and the ring-shaped rib 4.

[0043] In the present disclosure, the periphery of the balancing ring body is provided with a ring-shaped rib, multiple drainage holes are disposed between the balancing ring body and the ring-shaped rib, so that the drainage holes are located on the top of the inner tub, and penetrate from top to bottom, thus the drainage is not affected by the balancing ring. Therefore, the drainage is smoother, and the drainage and dewatering efficiency are higher. The position of the drainage holes is higher, so that when the washing speed is low, even if the water rises along the tub wall under the action of washing centrifugal force, the water will fall back into the tub at the top, thereby effectively preventing washing water from rising along the tub wall and overflowing from the drainage holes.

[0044] The ring-shaped rib is arranged in the periphery of the balancing ring body, the ring-shaped rib and the balancing ring body are coaxially arranged, the height of the ring-shaped rib is preferably less than or equal to the height of the balancing ring body.

[0045] As shown in FIG. 1 to FIG. 5, this embodiment provides a washing machine balancing ring. There is a gap between the ring-shaped rib and the balancing ring body, the ring-shaped rib is connected to the balancing ring body through a connecting structure, and the connecting structure is provided with multiple drainage holes 5.

[0046] There is a gap between the balancing ring body and ring-shaped rib in the periphery, so as to facilitate the setting of the top drainage hole, and the balancing ring body and the ring-shaped rib are connected by the connecting structure, therefore, the balancing ring can be installed by fixing the ring-shaped rib, the structure is simple, and the fixation is easy.

[0047] Further, the connecting structure comprises reinforcing ribs 6 and/or a ring-shaped plate (not marked), so that the following solutions can be used for the setting between the ring-shaped rib and the balancing ring body:

[0048] Method 1: as shown in FIG. 4, the balancing ring body 2 and the ring-shaped rib 4 are connected by multiple reinforcing ribs 6. There is a gap between the adjacent reinforcing ribs, thereby forming the drainage holes 5. The reinforcing ribs are longitudinal reinforcing ribs. The longitudinal reinforcing ribs can be the same height as the ring-shaped rib, so as to form a passage, or can also be less than the height of the ring-shaped rib. The space between the outer side wall of the balancing ring and the inner side wall of the ring-shaped rib can be divided into small areas to facilitate drainage. This method has simple structure, good connecting and supporting effect, can form large drainage holes, can drain water smoothly and has good drainage effect.

[0049] Method 2: the balancing ring body and the ring-shaped rib are connected by a ring-shaped plate, and multiple drainage holes are distributed in the ring-shaped plate; the inner ring of the ring-shaped plate is fixed to the balancing ring body, and the outer ring of the ring-shaped plate is fixed to the ring-shaped rib, so that the supporting, connecting and fixing effects are better; and meanwhile, multiple circles of drainage holes can be arranged on the ring-shaped plate, so that a good drainage effect can be achieved.

[0050] Method 3: the balancing ring body is connected to the ring-shaped rib by the reinforcing ribs and the ring-shaped plate, the reinforcing ribs are arranged on one side of the ring-shaped plate or penetrate through the ring-shaped plate, and the ring-shaped plate between adjacent reinforcing ribs is provided with drainage holes. The combination of the method 1 and the method 2 can further improve the connecting and supporting effects, and be also conducive to keeping the deformation of the inner tub assembly small during rotating at high speed, so as to reduce the vibration noise when the washing machine performs dewatering. At the same time, multiple drainage holes can be arranged to achieve the effect of smooth drainage. In addition, the inner tub assembly of the present disclosure is the whole inner tub, comprising the tub body, the tub bottom and the balancing ring.

[0051] Method 4: as shown in FIG. 5, the connecting structure comprises an outer ring-shaped convex rib 7 that is disposed on the balancing ring body and is convex in a peripheral direction, the upper end of the ring-shaped rib 4 is bent inwardly and is fixedly connected to the outer ring-shaped convex rib 7, and the outer ring-shaped convex rib is provided with multiple drainage holes 5. The balancing ring body of the method is provided with a ring-shaped convex rib, and is connected with the ring-shaped rib in a wrapping manner to achieve fixation. The fixing effect is slightly poor, but the structure is simple and the implementation is easy. The ring-shaped convex rib and the part, wrapping the ring-shaped convex rib, of the ring-shaped rib are correspondingly provided with drainage holes that penetrate from top to bottom. Therefore, the drainage can also be achieved, and are not affected by the balancing ring, so as to achieve effect of smooth drainage.

Embodiment 2

[0052] As shown in FIG. 2 to FIG. 4, a balancing ring body 2 is provided with a ring-shaped water-retaining rib 9 which is convex in the periphery direction of the balancing ring body, and the ring-shaped water-retaining rib is arranged above the water outlet end of the drainage holes 5. The ring-shaped water-retaining rib is arranged above the water outlet end of the drainage holes, an appropriate distance away from the drainage holes is suggested to meet the following condition that the water that is ejected quickly can be blocked, and the smooth drainage is not hindered.

[0053] When the washing machine performs dewatering, the rotation speed is relatively high, and the water flow may be ejected rapidly from the drainage holes under the action of centrifugal force. The water flow can be blocked by the ring-shaped water-retaining rib that is arranged above the drainage holes, so as to avoid this situation and bad influence on the surrounding environment such as walls, thus enhancing user experience.

Embodiment 3

[0054] As shown in FIG. 2, the lower end of the balancing ring body of this embodiment is provided with a downward lower ring-shaped rib 10, there is a gap between the outer wall of the lower ring-shaped rib 10 and the inner wall of the ring-shaped rib 4, thereby forming a drainage passage 11.

[0055] Further, the drainage passage is composed of a plurality of longitudinally arranged passages, and top end of each passage is provided with at least one drainage hole.

[0056] Preferably, each passage is mainly composed of a lower ring-shaped rib that coordinates with a longitudinal reinforcing rib and a ring-shaped rib.

[0057] For the structure of this embodiment, on the top of the inner tub, the drainage passage is formed by using the lower ring-shaped rib below the balancing ring and the ring-shaped rib in the periphery, which facilitates the rising of the water in the inner tub and facilitates the smooth drainage. Combined with the longitudinal reinforcing ribs, a plurality of longitudinally arranged passages are formed, the top end of each passage is provided with a drainage hole, so as to further increase the drainage speed and improve dewatering efficiency.

Embodiment 4

[0058] As shown in FIG. 1 to FIG. 5, a water-saving washing machine inner tub of the present disclosure comprises a tub body 1 and a tub bottom 3 mounted on a lower portion of the tub body, wherein the balancing ring is mounted on the opening of the tub body, the ring-shaped rib 4 is fixedly connected to the upper end of the tub body 1, and the tub body 1 and the tub bottom 3 are each of a sealed structure.

[0059] The balancing ring is mounted on the upper portion of the tub body. The ordinary non-porous inner tub is only provided with a circle of dewatering holes in the tub wall below the balancing ring, or notches are formed at the bottom of the balancing ring to form a drainage groove. During draining, the inner tub rotates at a high speed, thus generating a large centrifugal force. Therefore, the water in the inner tub and the clothes can be discharged from the drainage holes in the side wall, but when the water rises to the top, part of the water will fall back into the inner tub under the action of the top balancing ring, thus greatly affecting the drainage and dewatering efficiency. The periphery of the balancing ring of the present disclosure is provided with a ring-shaped rib, and a plurality of drainage holes are arranged between the ring-shaped rib and the balancing ring. During centrifugal dewatering, the water in the inner tub rises to the top and is directly discharged without being affected by the balancing ring, so that the drainage is smoother and the drainage and dewatering are more efficient. The drainage holes in the application are positioned at the top end, the position of the drainage holes is raised, and the tub top and the tub bottom are each of a sealed water storage structure, so that the washing water can be prevented from overflowing from the drainage holes, the overflowing of the washing water caused by splashing of the washing machine is effectively prevented or reduced, and water can be saved; and meanwhile, the ring-shaped rib is fixedly connected with the upper end of the tub body, so that the riveted structural strength between the inner tub and the balancing ring is higher, in such a way, when the washing machine performs dewatering, the deformation of the inner tub assembly is smaller, thus reducing vibration noise during dewatering of the washing machine.

[0060] Further, the ring-shaped rib 4 of the balancing ring is inserted into the opening of the tub body 1, and the upper end of the tub body 1 is fixedly connected to the ring-shaped rib 4.

[0061] Preferably, the upper end of the tub body is bent from the outside to the inside and wraps the ring-shaped rib, and the upper end of the tub body is fixedly riveted with the ring-shaped rib.

[0062] Through the above manner, the upper end of the tub body can wrap the ring-shaped rib therein and perform riveted fixing. The fixing strength is higher, so that when the washing machine performs dewatering, the deformation of the inner tub body assembly is small, thereby reducing the vibration noise during the dewatering of the washing machine. Simultaneously, sealed connection between the ring-shaped rib and the tub body can be achieved to prevent water from entering the outer tub.

Embodiment 5

[0063] As shown in FIG. 1 to FIG. 4, the tub body of this embodiment is provided with a ring-shaped constricting structure 8 having an inner diameter smaller than the inner diameter of the tub body below the balancing ring, and the constricting structure 8 is a ring-shaped protrusion that is concave by the tub body from outside to the inside and is formed in the inner wall of the tub body, or the constricting structure 8 is an inner ring-shaped convex rib disposed circumferentially on the inner wall of the tub body.

[0064] The constricting structure is a circle of protrusion at the upper end of the tub body, where the protrusion is pressed from outside to inside and faces the inner wall of the tub body. In the case of washing, that is, the rotation speed is lower, the washing water that rises along the inner tub under the action of centrifugal force during the washing can flow back into the inner tub at the structure without being discharged from the drainage holes at the upper end, and the fixation of the ring-shaped rib is facilitated.

[0065] Further, the ring-shaped rib 4 of the balancing ring is inserted into the constricting structure 8, and the upper end of the constricting structure is fixedly connected to the ring-shaped rib. The ring-shaped rib is clamped in the constricting structure and is connected to the constricting structure, so as to realize the fixing of the balancing ring, and the installation is simple and the implementation is easy.

[0066] Preferably, the upper end of the constricting structure is bent from the outside to the inside and wraps the ring-shaped rib, and the upper end of the constricting structure is fixedly riveted with the ring-shaped rib. This manner not only can enhance the fixation strength, but also can achieve sealing, so as to prevent water from flowing into the outer tub.

[0067] Preferably, the upper end of the tub body is bent at a degree of 180 from the outside to the inner wall, wraps the ring-shaped rib, and is fixedly riveted with the ring-shaped rib.

[0068] When the upper end of the tub body is bent at a degree of 180 from the outside to the inner wall, the upper end of the tub body can wrap the ring-shaped rib therein and perform riveted fixing. The fixing strength is higher, full sealing can be achieved, so that when the washing machine performs dewatering, the deformation of the inner tub body assembly is small, thereby reducing the vibration noise during the dewatering of the washing machine. Simultaneously, water can be prevented from flowing into the outer tub.

Embodiment 6

[0069] The embodiment provides a washing machine, and the washing machine is provided with the above-mentioned washing machine inner tub.

[0070] The washing machine of the present disclosure is a full-automatic washing machine, and can be a turbine full-automatic washing machine, a dual power washing machine, and the like. During washing, the inner tub rotates at a low speed, and the washing water rises along the tub wall. When reaching the constricting structure at the upper end of the tub body, the washing water can fall back into the tub body, even if the water level is higher, the rising washing water will not overflow from the drainage holes at the top end. During drainage or dewatering, the inner tub rotates at a very high speed, and the water in the inner tub rises along the tub wall and is discharged from the drainage holes between the balancing ring body and the ring-shaped rib. The drainage is not affected by the balancing ring and is smoother, and the dewatering efficiency is higher. At the same time, the balancing ring body and the ring-shaped rib are fixed by the longitudinal reinforcing ribs, the ring-shaped rib is wrapped by the upper end of the tub body that is folded inwardly at a degree of 180 , and the ring-shaped rib and the upper end of the tub body are riveted by rolling riveting to be fixed, so that the fixing strength is high, the sealing is good. And when the washing machine performs dewatering, the deformation of the inner tub assembly is smaller, thus reducing the vibration noise during the dewatering of the washing machine and preventing water from flowing into the outer tub.
