Description

Technical Field

[0001] The utility model belongs to the technical field of washing equipment, and particularly relates to a balance ring of a washing equipment and a washing equipment with the balance ring. Background Art

[0002] During the operation of a washing machine, due to the uneven distribution of the washing objects, the center of the barrel during rotation does not completely coincide with the center of the barrel, which may cause the barrel to be eccentric, and further cause the barrel and the washing machine cabinet to collide, reducing the user experience.

[0003] In the prior art, in order to reduce the eccentricity of the barrel, a balance ring is usually provided at the top of the barrel. The balance ring has an annular cavity inside, which is filled with a balance medium. A partition for blocking the balance medium is also provided inside the cavity. When the barrel rotates and becomes eccentric, the balance medium is concentrated on the other side opposite to the eccentric direction under the action of hysteresis and the blocking of the partition, compensating for the offset of the barrel center, thereby correcting the eccentricity, reducing the running noise of the washing machine, and avoiding damage to the washing machine caused by collision.

[0004] The patent with the application number CN201711341747.3 discloses a washing machine balance ring, which includes a first balance part and a second balance part. The first balance part and the second balance part are cladded to form a sealed cavity. The sealed cavity includes a first cladding surface close to the inner side of the ring and a second cladding surface close to the outer side of the ring. The second cladding surface includes an inner cladding surface close to the inner side of the ring and an outer cladding surface close to the outer side of the ring. The sealed cavity formed by the first cladding surface and the inner cladding surface forms a first flow channel, and the sealed cavity formed by the inner cladding surface and the outer cladding surface forms a second flow channel, which improves the deviation correction ability of the balance ring through the double flow channels. Although the above solution provides a balance ring with deviation correction ability, due to the limitation of the cross-sectional area of the internal flow channel of the balance ring, the amount of the balance medium that can be filled is small, and when the eccentricity is relatively serious, there may be a problem that the deviation correction force provided by the balance ring is not enough to correct the eccentricity.

[0005] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Invention

[0054] See Figures 1-6 , which is an embodiment of a balance ring of a washing device proposed by the present utility model. A balance ring 100 of a washing device is fixedly provided on a rotatably provided washing tub. The balance ring 100 may be fixedly provided on the upper part of the washing tub or may be provided at the bottom of the washing tub. Taking the balance ring 100 being provided at the bottom of the washing tub as an example for explanation, the balance ring 100 is fixedly provided on the inner tub bottom 200. The balance ring 100 being provided at the bottom of the washing tub is beneficial to reducing the space occupied in the washing device cabinet and is also beneficial to making the distance between the center of gravity of the balance ring and the washing tub closer, achieving a better deviation correction effect.

[0055] In this embodiment, the balance ring 100 includes: a plurality of receiving cavities 10 spaced circumferentially, and connection channels 20 provided between two adjacent receiving cavities 10. Both the receiving cavities 10 and the connection channels 20 extend circumferentially. A balance medium is injected into the receiving cavities 10, and the connection channels 20 are used to enable the flow of the balance medium between the adjacent receiving cavities 10. Each receiving cavity 10 has two end walls 11 arranged radially, and the connection channels 20 are arranged between the two end walls 11 of two adjacent receiving cavities 10. By providing the connection channels 20, for the flow of the balance medium between two adjacent receiving cavities 10, it needs to pass through the connection channels 20. Firstly, the cross-section of the connection channels 20 is much smaller than that of the receiving cavities 10, so that the flow rate of the balance medium between the two receiving cavities 10 is small. Secondly, the connection channels 20 extend circumferentially, and the balance medium needs to flow a certain distance circumferentially through the connection channels 20 to reach the adjacent receiving cavity 10. Therefore, it is beneficial to delay the flow rate of the balance medium between adjacent receiving cavities 10 and beneficial to improve the deviation correction ability.

[0056] In some embodiments of the present application, the connection channel 20 has an inner connection channel 21 located on the inner side and an outer connection channel 22 located on the outer side. By providing the inner connection channel 21 and the outer connection channel 22, when the washing tub rotates at a low speed, the centrifugal force on the balance medium in the receiving cavity 10 is small, and the flow of the balance medium between adjacent receiving cavities mainly passes through the inner connection channel 21. When the washing tub rotates at a high speed, the centrifugal force on the balance medium in the receiving cavity 10 is relatively large, and the balance medium moves outward and upward in the receiving cavity 10, and the flow of the balance medium between adjacent receiving cavities 10 mainly passes through the outer connection channel 22. This can ensure the flow of the balance medium between adjacent receiving cavities and improve the adaptability of the balance ring to different working conditions.

[0057] In some embodiments of the present application, the receiving cavity 10 has a top wall 12, and a connection top 25 is connected between two adjacent receiving cavities 10. A plurality of top walls 12 and a plurality of connection tops 25 are connected in sequence to form a top plate. The top wall 12 and the connection top 25 are arranged flush, so that a top plate of the annular balance ring 10 can be formed. The upper end surfaces of the top wall 12 and the connection top 25 are coplanar. When the balance ring 100 is installed and fixed to the washing tub, the top plate of the balance ring 10 contacts the inner barrel bottom 200, which is beneficial to increase the contact area and improve the firmness of the fixation. It further includes a plurality of fixing ears 30 extending inwards along the top plate. The plurality of fixing ears 30 are spaced circumferentially, and fixing holes 31 are provided on the fixing ears 30. The balance ring 100 is installed and fixed to the washing tub by a plurality of screws.

[0058] In some embodiments of the present application, the end wall 11 is connected to the top plate. An inner connection hole connected to the inner connection channel 21 and an outer connection hole connected to the outer connection channel 22 are provided in the end wall 11. Both ends of the inner connection channel 21 are connected to two inner connection holes provided in two adjacent end walls 11; both ends of the outer connection channel 22 are connected to two outer connection holes provided in two adjacent end walls 11.

[0059] In some embodiments of the present application, the top of the inner connection channel 21 is the connection top 25, and the top of the outer connection channel 22 is the connection top 25. The inner connection channel 21 and the outer connection channel 22 are arranged at intervals in the radial direction. Both the inner connection channel 21 and the outer connection channel 22 extend downward from the connection top 25, which is beneficial to realizing the integral injection molding of the balance ring 10.

[0060] In some embodiments of the present application, the accommodation cavity 10 has an arc-shaped inner cavity wall 13. The inner connection channel 21 has a first inner side wall 213 connected to the inner cavity wall 13, and the inner cavity wall 13 and the first inner side wall 213 are coaxially arranged. The inner connection channel 21 is arranged on the inner diameter side of the accommodation cavity 10, so that the inner connection channel 21 and the outer connection channel 22 are as far away from each other as possible in the radial direction, so that the balance medium does not pass through the inner connection channel 21 when the washing tub rotates at a high speed, improving the blocking effect on the balance medium and increasing the deviation correction ability.

[0061] In some embodiments of the present application, the accommodation cavity 10 has an arc-shaped outer cavity wall 14. The outer connection channel 22 has a second outer side wall 224 connected to the outer cavity wall 14, and the outer cavity wall 14 and the second outer side wall 224 are coaxially arranged. The outer connection channel 21 is arranged on the outer diameter side of the accommodation cavity 10, so that the inner connection channel 21 and the outer connection channel 22 are as far away from each other as possible in the radial direction, so that the balance medium only passes through the outer connection channel 22 when the washing tub rotates at a high speed, improving the blocking effect on the balance medium and increasing the deviation correction ability.

[0062] In some embodiments of the present application, the inner connection channel 21 has a first outer side wall 214 coaxially arranged with the first inner side wall 213, and the first outer side wall 214 is sleeved on the outside of the first inner side wall 213. The outer connection channel 22 has a second inner side wall 223 coaxially arranged with the second outer side wall 224, and the second outer side wall 224 is sleeved on the outside of the second inner side wall 223. The first outer side wall 214 and the second inner side wall 223 are coaxially arranged at intervals.

[0063] In some embodiments of the present application, the balancing medium in the accommodation cavity 10 is generally at about half the height of the accommodation cavity 10. In the static state, the balancing medium is set to reach the inner connection channel 21, and the balancing medium cannot reach the outer connection channel 22. When the washing tub rotates at a low speed, the centrifugal force on the balancing medium in the accommodation cavity 10 is small, and the circulation of the balancing medium between adjacent accommodation cavities mainly passes through the inner connection channel 21; when the washing tub rotates at a high speed, the centrifugal force on the balancing medium in the accommodation cavity 10 is relatively large, and the balancing medium moves outward and upward in the accommodation cavity 10, and the circulation of the balancing medium between adjacent accommodation cavities 10 mainly passes through the outer connection channel 22.

[0064] Specifically, the inner connection channel 21 has a first bottom wall 211, the outer connection channel 22 has a second bottom wall 221, and the plane where the first bottom wall 211 is located is lower than the second bottom wall 221; the liquid level of the balancing medium in the accommodation cavity 10 is higher than the first bottom wall of the inner connection channel 21. At this time, the balancing medium is distributed in the inner connection channel 21, and the circulation of the balancing medium in adjacent accommodation cavities 10 is realized by flowing through the inner connection channel 21. The liquid level of the balancing medium in the accommodation cavity 10 is lower than the second bottom wall of the outer connection channel 22. At this time, the balancing medium cannot reach the outer connection channel 22.

[0065] In some embodiments of the present application, the cross-sectional area of the inner connection channel 21 is larger than the cross-sectional area of the outer connection channel 22. When the washing tub rotates at a low speed, while the inner connection channel 21 delays and blocks the balancing medium, it allows a relatively larger amount of the balancing medium to flow between adjacent accommodation cavities 10 through the inner connection channel 21, avoiding the problem of excessive deviation correction caused by the slow flow of the balancing medium in the balance ring during low-speed rotation. When the washing tub rotates at a high speed, while the outer connection channel 22 delays and blocks the balancing medium, it allows a relatively smaller amount of the balancing medium to flow between adjacent accommodation cavities 10 through the outer connection channel 21, which is beneficial to improving the deviation correction ability of the balance ring. Here, both the low-speed rotation and the high-speed rotation are a range of rotational speeds, and in the intermediate rotational speed region between low speed and high speed, the inner connection channel 21 and the outer connection channel 22 can both play a role in the circulation of the balancing medium. The specific numerical ranges of low speed and high speed are related to the size data of the balance ring itself, the height of the liquid level of the balancing medium in the accommodation cavity 10, and the specific gravity of the balancing medium, etc.

[0066] In some embodiments of the present application, the radial dimension of the inner connection channel 21 is greater than the radial dimension of the outer connection channel 22; the ratio of the radial dimension inside the accommodation cavity 10 to the radial dimension inside the inner connection channel 21 is 4 to 6, preferably set, and the ratio of the radial dimension inside the accommodation cavity 10 to the radial dimension inside the inner connection channel 21 is 5 to 5.8. The ratio of the radial dimension inside the accommodation cavity 10 to the radial dimension inside the outer connection channel 22 is 7 to 10, preferably set, and the ratio of the radial dimension inside the accommodation cavity 10 to the radial dimension inside the outer connection channel 22 is 8 to 9.

[0067] In some embodiments of the present application, the axial dimension inside the inner connection channel 21 is greater than the axial dimension inside the outer connection channel 22. The ratio of the axial dimension inside the inner connection channel 21 to the axial dimension inside the outer connection channel 22 is 2 to 3; preferably, the ratio of the axial dimension inside the inner connection channel 21 to the axial dimension inside the outer connection channel 22 is 2.5 to 3.

[0068] In some embodiments of the present application, the ratio of the axial dimension inside the accommodation cavity 10 to the axial dimension inside the inner connection channel 21 is 1 to 2; preferably, the ratio of the axial dimension inside the accommodation cavity 10 to the axial dimension inside the inner connection channel 21 is 1.4 to 1.6; more preferably, the ratio of the axial dimension inside the accommodation cavity 10 to the axial dimension inside the inner connection channel 21 is 1.5.

[0069] In some embodiments of the present application, the ratio of the axial dimension inside the accommodation cavity 10 to the axial dimension inside the outer connection channel 22 is 4 to 5; preferably, the ratio of the axial dimension inside the accommodation cavity 10 to the axial dimension inside the outer connection channel 22 is 4 to 4.5.

[0070] In some embodiments of the present application, the ratio of the circumferential dimension of the accommodation cavity 10 to the circumferential dimension of the outer connection channel 22 is 12 to 16; preferably, the ratio of the circumferential dimension of the accommodation cavity 10 to the circumferential dimension of the outer connection channel 22 is 14 to 15. Figure 1 The shown balance ring 100 is provided with twelve accommodation cavities 10 and 12 connection channels 20 in the circumferential direction. The central angle corresponding to each accommodation cavity 10 in the circumferential direction is 28°, and the central angle corresponding to each connection channel 20 in the circumferential direction is 2°.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, for those of ordinary skill in the art, it is still possible to modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions required to be protected by the present invention.
