Description

Technical Field

[0001] The utility model belongs to the technical field of washing machines, and particularly relates to a washing machine balance ring for preventing clothes from getting stuck in the gap. Background Art

[0002] In order to reduce the vibration caused by the eccentricity of clothes, in the prior art, a balance ring is usually installed at the top of the inner barrel of a pulsator washing machine. The balance ring is filled with a balance medium. When the inner barrel rotates at high speed during dehydration and spin-drying, the lag of the flow of the balance medium in the balance ring is used to compensate for the eccentric force of the high-speed rotating inner barrel, thereby playing a balancing role.

[0003] In order to prevent the failure phenomenon of the spin barrel hitting the wall during the operation of the inner barrel of the washing machine, a gap is left between the inner barrel, the outer barrel and the balance ring (refer to Figure 4 shown). When there are more clothes to be washed, during the washing and dehydration process of the clothes, due to the tumbling during the washing process and the huge centrifugal force generated by the high-speed rotation during dehydration, some clothes are likely to enter the movement gap between the inner barrel and the outer barrel, resulting in clothes wear and poor user experience.

[0004] In view of this, a washing machine balance ring for preventing clothes from getting stuck in the gap is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a washing machine balance ring for preventing clothes from getting stuck in the gap in order to solve the above-mentioned problems.

[0006] The technical scheme adopted by the utility model is as follows: A washing machine balance ring for preventing clothes from getting stuck in the gap, comprising: an outer barrel, at the barrel opening of which there is an annular outer barrel cover; an inner barrel, which is rotatably arranged in the outer barrel, and there is a movement gap between the inner barrel and the outer barrel; a balance ring, which is arranged at the top of the inner barrel, and at the inner edge of the top of the balance ring there is an annular convex surface matching the shape of the outer barrel cover, and a gap inlet is formed by surrounding between the annular convex surface and the outer barrel cover, and the gap inlet is inclined upwards and communicated with the movement gap.

[0007] In a preferred embodiment, the balance ring comprises a upper half ring part and a lower half ring part which are buckled together, and the annular convex surface and the upper half ring part are integrally formed.

[0008] In a preferred embodiment, a retaining ring smaller than the aperture of the outer barrel cover is formed circumferentially at the top end of the annular convex surface, and the retaining ring extends upwards inside the outer barrel cover.

[0009] In a preferred embodiment, the balance ring internally has an annular cavity coaxial with it for accommodating a balance medium.

[0010] In a preferred embodiment, a stepped groove is formed by inward depression on the outer peripheral surface of the bottom of the lower half ring portion, and the top of the inner barrel is sleeved on the outer end of the stepped groove.

[0011] To sum up, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows: The new design changes the shape of the balance ring, and a ring-shaped convex surface matching the shape of the outer barrel cover is designed on the upper end surface of the balance ring, which can change the direction of the movement gap inlet. Without increasing the cost, the problem of clothes entering the movement gap and wearing during the washing and dehydration process can be avoided, providing a better user experience and being worthy of promotion.

[0017] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] Referring to Figures 1-4 , a washing machine balance ring for preventing clothes from getting stuck in the gap includes: an outer barrel 1, an annular outer barrel cover 101 is provided at the barrel opening thereof, an inner barrel 2, which is rotatably arranged inside the outer barrel 1, and there is a movement gap 4 between the inner barrel 2 and the outer barrel 1. By designing the movement gap 4, the phenomenon of the dehydration and spinning bucket hitting the wall can be avoided when the inner barrel 2 rotates for dehydration and spinning.

[0019] Further, a balance ring 3 is provided at the top of the inner tub 2. An annular convex surface 302 matching the shape of the outer tub cover 101 is provided at the inner edge of the top of the balance ring 3. A gap inlet 5 is formed by enclosing between the annular convex surface 302 and the outer tub cover 101. The gap inlet 5 is inclined upward and communicates with the movement gap 4. The new design changes the shape of the balance ring 3. An annular convex surface 302 matching the shape of the outer tub cover 101 is designed on the upper end surface of the balance ring 3, which can change the direction of the gap inlet 5. Without increasing the cost, the problem of clothes entering the movement gap and being worn during the washing and dehydration process can be avoided, and the user experience is better, which is worthy of promotion.

[0020] It should be emphasized here that the above method of preventing clothes from getting stuck in the seam only changes the direction of the gap inlet 5 and does not change the size of the gap spacing. While preventing clothes from getting stuck in the seam, it can also avoid the phenomenon of the spin tub hitting the wall at the same time.

[0021] Further, the balance ring 3 includes a upper half ring portion and a lower half ring portion that are buckled together. The annular convex surface 302 and the upper half ring portion are integrally formed parts. Since the annular convex surface 302 and the upper half ring portion are integrally formed parts, while ensuring the overall strength, the overall manufacturing process and cost can also be reduced.

[0022] Further, the balance ring 3 has an annular cavity 301 coaxial with it inside, which is used to accommodate the balance medium. The balance ring is filled with the balance medium. When the inner tub 2 rotates for dehydration and drying, the eccentricity of the high-speed rotating inner tub 2 is compensated by the lag of the flow of the balance medium in the balance ring 3, thus playing a balancing role.

[0023] Among them, the balance medium is preferably brine.

[0024] Further, a retaining ring smaller than the aperture of the outer tub cover 101 is formed circumferentially at the top end of the annular convex surface 302, and the retaining ring extends upward and is arranged inside the outer tub cover 101.

[0025] Further, a stepped groove 303 is formed by inwardly recessing the outer peripheral surface of the bottom of the lower half ring portion. The top of the inner tub 2 is sleeved on the outer end of the stepped groove 303. By designing the stepped groove 303, the balance ring 3 can be integrally lapped on the inner tub 2, which can improve the combination strength between the subsequent inner tub 2 and the balance ring 3.

[0026] To sum up, an annular convex surface 302 matching the shape of the outer tub cover 101 is designed on the upper end surface of the balance ring 3, which can change the direction of the movement gap inlet. Without increasing the cost, the problem of clothes entering the movement gap 4 and being worn during the washing and dehydration process can be avoided, and the user experience is better.

[0027] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
