The balance ring 40 is connected to the inner cylinder 20 to rotate with the inner cylinder 20, and the center axis of the balance ring 40 is parallel or coincident with the rotation axis of the inner cylinder 20.
In some specific examples of the present invention, as shown in fig. 13, there are two balancing rings 40, and two balancing rings 40 are provided at both axial ends of the inner tube 20, respectively. Thus, the balance adjustment operation can be performed from both ends of the inner cylinder 20, and the adjustment effect is better.
According to the balancing ring 40 for the laundry treating apparatus of the embodiment of the present invention, by dividing the balancing ring body 100 into the plurality of splicing sections 210 arranged along the circumferential direction thereof, each splicing section 210 is individually formed, the size of a single forming part is reduced, the mold is more easily ejected, the cost of the mold is reduced, the production is more convenient, and the mass production is facilitated.

In some embodiments of the present invention, as shown in fig. 1-8, the water inlets 120 of the plurality of water distribution cavities 110 are disposed on the inner circumferential surface of the weight ring body 100, and the water inlets 120 of the plurality of water distribution cavities 110 are disposed at intervals along the axial direction of the weight ring body 100.
Further, the water inlets 120 of the plurality of water distribution cavities 110 are staggered in the circumferential direction of the weight ring body 100, so as to accurately fill water into the target water distribution cavities 110.
It should be understood that each water distribution cavity 110 may also have a plurality of water inlets 120, and the plurality of water inlets 120 of the same water distribution cavity 110 are disposed at intervals along the circumferential direction of the weight ring body 100, in this embodiment, the water inlets 120 of the plurality of water distribution cavities 110 refer to water inlets 120 of different water distribution cavities 110, that is, the water inlets 120 of different water distribution cavities 110 are disposed at intervals along the axial direction of the weight ring body 100, and the water inlets 120 of different water distribution cavities 110 are disposed in a staggered manner along the circumferential direction of the weight ring body 100.
In some specific examples of the present invention, as shown in fig. 1, 4, 7 and 8, the inner circumferential surface of the weight ring body 100 is provided with a plurality of water channel ribs 400, the plurality of water channel ribs 400 define a plurality of water channel grooves 410 on the inner circumferential surface of the weight ring body 100, each water channel groove 410 extends along the circumferential direction of the weight ring body 100, and the plurality of water channel grooves 410 are spaced apart along the axial direction of the weight ring body 100. The number of the water channel grooves 410 is identical to the number of the water distribution cavities 110, the plurality of water channel grooves 410 are communicated with the water inlets 120 of the plurality of water distribution cavities 110 in a one-to-one correspondence, and the plurality of water channel grooves 410 are independent from each other, i.e., water in each water channel groove 410 can flow into a predetermined one of the water distribution cavities 110 through the corresponding water inlet 120. The water inlets 120 of the different water distribution cavities 110 are separated by the plurality of water channel ribs 400, so that water is prevented from flowing into the other water distribution cavities 110 when water is injected into one of the water distribution cavities 110, and accurate water injection is facilitated. Wherein each of the water course bars 400 is divided into a plurality of portions respectively belonging to the plurality of splice segments 210 in the circumferential direction of the ferrule body 100.
Further, as shown in fig. 8, each of the water channel grooves 410 has a notch facing the central axis of the weight ring body 100 in the radial direction of the weight ring body 100, and water blocking ribs 411 are provided at the notch of each of the water channel grooves 410, that is, water blocking ribs 411 extending in the axial direction of the weight ring body 100 are provided at the inner periphery of the water channel ribs 400, and it is understood that, for the plurality of water channel ribs 400, since only one side is used to define the water channel groove 410 for the two water channel ribs 400 located at the outermost side in the axial direction of the weight ring body 100, the cross section of the water channel ribs 411 is L-shaped, whereas the water channel ribs 400 located at the inner side in the axial direction of the weight ring body 100 are T-shaped since both sides are used to define the water channel grooves 410, respectively, and therefore the cross section of the water channel ribs 400 located at the inner side is T-shaped. In this way, the water blocking rib 411 can prevent water from splashing during water spraying toward the waterway groove 410.
In some embodiments of the present invention, as shown in fig. 1-12, a plurality of partition plates 130 are disposed in the weight ring body 100, the plurality of partition plates 130 are disposed at intervals along the circumferential direction of the weight ring body 100, and the plurality of partition plates 130 divide the interior of the weight ring body 100 into a plurality of water distribution cavities 110, i.e., separate the interior of the weight ring body 100 into a plurality of water distribution cavities 110 by using the plurality of partition plates 130.
In some specific examples of the present invention, as shown in fig. 1 to 3, the number of the spliced segments 210 is identical to the number of the water distribution cavities 110, and the connection position of the adjacent spliced segments 210 is located at the center between the adjacent separators 130 in the circumferential direction of the balance weight ring body 100. For example, the counterweight ring body 100 has three water distribution cavities 110, and is formed by sequentially splicing three splicing sections 210 end to end, and the connection position (i.e., the dividing position) of two adjacent splicing sections 210 is between two separators 130, preferably at the middle between two separators 130.
For the three water inlets 120, the water inlet 120 is positioned at the middle in the axial direction of the counterweight ring body 100, and the water inlet 120 and the partition 130 are symmetrically arranged relative to the axial middle surface of the counterweight ring body 100; the water inlets 120 are axially located at two sides of the counterweight ring body 100, the distances between the two water inlets in the axial direction of the counterweight ring body 100 and the center of the axial width of the counterweight ring body are equal, and the distances between the two water inlets 120 and the adjacent ends of the splicing section 210 are equal along the circumferential direction of the counterweight ring body 100, so that a symmetrical structure is formed, and the reduction of the number of dies is facilitated.
In other specific examples of the present invention, as shown in fig. 4 to 6, the number of the spliced segments 210 is identical to the number of the water distribution cavities 110, and the connection positions of the adjacent spliced segments 210 are immediately adjacent to the same side of the partition 130 in the circumferential direction of the ferrule body 100. For example, the counterweight ring body 100 has three water distribution cavities 110, and is formed by sequentially splicing three splicing sections 210 end to end, the connection positions (i.e., the dividing positions) of two adjacent splicing sections 210 are adjacent to the same side of the partition 130 in the circumferential direction of the counterweight ring body 100, and each dividing position is located at the counterclockwise side of the corresponding partition 130 in the circumferential direction of the counterweight ring body 100 in the views shown in fig. 5 and 6, so as to form a symmetrical structure, thereby facilitating the reduction of the number of dies.
Optionally, adjacent splice segments 210 are hot melt joined or snap joined.
In some embodiments of the present invention, as shown in fig. 7-12, a water baffle 300 is disposed in the water distribution cavity 110, and the water baffle 300 has a water through hole 310, i.e. the water baffle 300 has a function of reducing the flow rate of water, but cannot completely block the water, so as to improve the balance effect of the balance ring 40.
However, since the plurality of water baffles 300 are disposed, the weight ring body 100 needs to be divided into a larger number of spliced segments 210, which affects the overall structural strength and manufacturing convenience of the weight ring body 100, so that the weight ring body 100 is further divided in the axial direction on the basis of dividing the weight ring body 100 circumferentially, and in order to improve the symmetry of the divided portions, the number of water baffles 300 in the water distribution cavity 110 of each spliced segment 210 is equal, and the water baffles 300 in the water distribution cavity 110 of each spliced segment 210 are disposed at equal intervals (i.e. uniformly distributed) along the length direction of the water distribution cavity 110.
Specifically, as shown in fig. 7 to 12, each of the splicing sections 210 includes a plurality of splicing blocks 220, the plurality of splicing blocks 220 are arranged along the axial direction of the balance weight ring body 100, and the plurality of splicing blocks 220 are respectively formed separately and sequentially connected along the axial direction of the balance weight ring body 100, that is, after the plurality of splicing blocks 220 are formed separately, the plurality of splicing sections 210 are spliced first, and then the plurality of splicing sections 210 are spliced into the balance weight ring body 100. The partition 130 is divided into a plurality of parts respectively belonging to the plurality of splice blocks 220 in the axial direction of the ferrule 100, and the present invention is not limited thereto, and since the water baffle 300 itself needs to be provided with the water through holes 310, the water baffle 300 may be divided into a plurality of parts in the axial direction (i.e., whether the number coincides with the splice blocks 220) according to the actual situation.
The water deflector 300 is divided into a plurality of portions respectively belonging to the plurality of splice blocks 220 in the axial direction of the ferrule body 100. Therefore, not only can the setting requirement of the water baffle 300 be met, but also the demolding can be facilitated, and the mold cost is reduced.
In some embodiments of the present invention, as shown in fig. 9, the connection position of the adjacent spliced segments 210 is located at the partition 130 in the circumferential direction of the balance weight ring body 100 and divides the partition 130 into two parts respectively belonging to the adjacent spliced segments 210. That is, the dividing positions of the adjacent splice segments 210 are provided on the partition 130, and the partition 130 is divided into a plurality of portions in the circumferential direction and the axial direction of the ferrule body 100, respectively, with the arrangement of the splice segments 210 and the splice blocks 220.
