It is understood that the balancing ring 1 according to the embodiment of the present invention is not limited to be applied only to the laundry treating apparatus 1000 of the structure shown in fig. 1 and 2, but may be applied to other structures of laundry treating apparatuses, as will be understood by those skilled in the art.

A laundry treating apparatus 1000 according to an embodiment of the present invention will be described below with reference to fig. 1 to 2 first.

Referring to fig. 1 to 3, a laundry treating apparatus 1000 according to some embodiments of the present invention may include a treating drum device 100, an apparatus case 200, a driving device 300, a control system, and the like. The process cartridge device 100 may be provided in the equipment enclosure 200, and the door assembly 400 may be provided on the equipment enclosure 200 to open and close the process cartridge device 100. Wherein the equipment enclosure 200 is optional, for example, in some alternative embodiments, the disposal bin assembly 100 may be exposed directly to the outside or embedded in a wall or cabinet.

As shown in fig. 2, the driving device 300 may be a driving motor, such as a direct-drive motor, to drive the processing drum device 100 to operate under the control of the control system. Optionally, the door assembly 400 is connected to the front of the processing barrel device 100, and the driving device 300 is connected to the rear of the processing barrel device 100, so that the operation habit is better met, and meanwhile, the driving device 300 can be hidden, and the driving effect is better.

According to some embodiments of the present invention, as shown in fig. 1, a processing cartridge assembly 100 may include an outer cartridge 30, an inner cartridge 20, and a gimbal assembly 10. The inner cylinder 20 is disposed in the outer cylinder cavity 310 of the outer cylinder 30, and the inner cylinder 20 has a rotation axis disposed horizontally or obliquely, that is, the rotation axis of the inner cylinder 20 is parallel to or oblique to a horizontal plane.

The center axis of the balance ring 1 is parallel to or coincident with the rotation axis of the inner cylinder 20, that is, the balance ring 1 may be disposed coaxially with the inner cylinder 20 or may be disposed eccentrically with respect to the inner cylinder 20. In order to ensure that the balance ring 1 has a good balance effect on the inner cylinder 20, when the balance ring 1 is eccentrically arranged, the eccentric distance may be smaller, for example, in some embodiments of the present invention, the distance between the central axis of the balance ring 1 and the rotation axis of the inner cylinder 20 may be set to be less than 5mm, for example, 2mm, 3mm, and the like.

The balance ring 1 may be used singly or in pairs. For example, as shown in fig. 1, in some embodiments of the present invention, the processing cartridge assembly 100 may include two balance rings 1, and the two balance rings 1 are respectively disposed at two axial ends of the inner cartridge 20. Thus, the operation of balance adjustment can be performed from both ends of the inner cylinder 20, and the adjustment effect is better. Of course, the balance ring 1 may be provided only at one end of the inner cylinder 20 to perform balance adjustment from one end of the treatment cylinder apparatus 100.

The water injection piece 2 can inject water into the balance ring 1, so that the gravity center of the balance ring 1 is changed, the eccentricity of the inner barrel 20 is adjusted, and the balance adjusting function is achieved. Alternatively, the control system may be connected to the water injection member 2 to control the water injection member 2 to actively inject water to the balance ring 1, so that the laundry treating apparatus 1000 has an active balance control function.

Alternatively, as shown in fig. 1, the water injection member 2 may be installed on the outer cylinder 30, and when the inner cylinder 20 drives the balance ring 1 to rotate, the water injection member 2 may be stationary, which not only facilitates manufacturing and installation, but also enables more stable water injection. The structure of the gimbal ring 1 will be further described below.

Referring to fig. 1 to 3, in some embodiments of the present invention, the balancing ring 1 includes a ring-shaped body 11, the body 11 has a chamber 101 therein, the body 11 has a water inlet 102, the water inlet 102 extends along the circumference of the body 11, and in some embodiments, the water inlet 102 is an annular opening provided in the body 11. Therefore, when the balance ring 1 rotates, the water injection piece 2 can inject water into the chamber 101 through the annular water inlet 102 more conveniently, and the water entering the chamber 101 is gathered on the outer wall surface of the chamber 101 under the action of centrifugal force and cannot flow out of the water inlet 102; when the balance ring 1 stops rotating, water can flow out through the water inlet 102 under the action of gravity, and the water drainage effect is good.

Referring to fig. 1 to 3, in some embodiments of the present invention, the notch of the water passage groove 103 (i.e., the water inlet 102) may be provided at an axial end surface of the body 11. Can follow axial one side of body 11 and carry out the water injection to body 11 like this, not only make things convenient for the water injection operation, the piece that injects water moreover need not to stretch into in the annular ring 1110 of body 11 to can not occupy the space of the annular ring 1110 of body 11, be favorable to the installation of clothes treatment facility's inner tube 20, can reduce the interference to inner tube 20, promote the section of thick bamboo capacity of inner tube 20.

In the embodiment shown in fig. 1 to 3, the number of the chambers 101 may be three, and the three chambers 101 are distributed along the circumferential direction of the body 11. Therefore, the balance control can be realized by controlling the water injection amount in the three chambers 101, and the control effect is good. With continued reference to fig. 1-3, the body 11 may be provided with three water channel grooves 103, the three water channel grooves 103 respectively extending along the circumferential direction of the body 11, and in some embodiments, the water channel grooves 103 may extend in a closed ring shape along the circumferential direction of the body. The three water passage grooves 103 may be arranged in a radial direction of the body 11. The three water channel grooves 103 are in one-to-one correspondence with the three chambers 101.

From this, control to the water injection volume of three cavity 101 can be realized through the water injection volume of controlling three water channel groove 103, when the required water yield of needs injection to corresponding cavity 101, can inject the required water yield to corresponding water channel groove 103 through water injection spare 2, and the water injection is more pointed, and is quicker to the eccentric balanced response of load, and it is higher to adjust efficiency, can effectively shorten the time of handling the clothing. Wherein, the notch of the water channel groove 103 is the water inlet 102.

It should be noted that, in the embodiment of the present invention, the number of the chambers 101 and the water channel grooves 103 is not limited to three as described above, and the number of the chambers 101 and the water channel grooves 103 may be set to other values, such as two, four or more, according to the requirements of balance control, manufacturing process and the like. The chambers 101 and the water channel 103 may be in the same number and correspond to each other, or may be in different numbers and correspond to each other. That is, in an embodiment of the present invention, each chamber 101 may communicate with at least one water channel groove 103 to feed water into the chamber through the water channel groove.

For example, the number of the water channel grooves 103 may be greater than the number of the chambers 101, some chambers 101 are respectively communicated with one water channel groove 103, and other chambers 101 are respectively communicated with at least two water channel grooves 103, that is, the water channel grooves 103 and the chambers 101 are in a many-to-one relationship.

For another example, in some alternative embodiments of the present invention, the number of the water passage grooves 103 is greater than the number of the chambers 101, the plurality of water passage grooves 103 includes a dedicated water passage groove communicating with only one chamber 101 and a common water passage groove communicating with at least two chambers 101, and each chamber 101 may have a dedicated water passage groove communicating with the chamber 101. Therefore, when water needs to be injected into one cavity 101, the water can be injected into the corresponding special water channel groove, water can be injected into other special water channel grooves and the public water channel groove, when water needs to be injected into at least two cavities 101, water can be injected into the corresponding special water channel groove, and water can be injected into the public water channel groove communicated with the at least two cavities 101 needing water injection.

For another example, in other alternative embodiments of the present invention, each water channel groove 103 is communicated with all the chambers 101, and the size of the opening 104 of each water channel groove 103 communicated with a plurality of chambers 101 is different, so that the water channel groove 103 can inject different amounts of water into the plurality of chambers 101, respectively, thereby achieving the adjustment of the balance.

Those skilled in the art can understand that, besides the adjustment of the water injection amount to each chamber 101 by controlling the water inlet state of the plurality of water channel slots 103 can be realized by controlling the number of the water channel slots 103 communicated with the chambers 101, the size of the openings 104 of the water channel slots 103 communicated with the plurality of chambers 101, and the like, the plurality of water channel slots 103 can be set to other structural forms as long as the requirement of adjusting the water injection amount of each chamber 101 by controlling the water inlet state of the plurality of water channel slots 103 can be satisfied, and the description is omitted here.

According to the balance ring 1 of the embodiment of the invention, the plurality of circumferentially distributed cavities 101 are arranged in the body 11, the plurality of water channel grooves 103 which are radially arranged and circumferentially extend are arranged on the body 11, water can be injected into the corresponding cavities 101 through the water channel grooves 103, and the water injection amount of each cavity 101 can be adjusted by controlling the water injection state of the plurality of water channel grooves 103, so that the distribution condition of the weight of the balance ring 1 along the circumferential direction can be realized, the centering of a load is realized, the balance adjustment is finally achieved, and the vibration of the clothes treatment equipment 1000 can be effectively reduced.

Referring to fig. 3 to 14, in some embodiments of the present invention, the axially outer side of the body 11 may be provided with a plurality of water channel ribs 1102, the plurality of water channel ribs 1102 may be arranged in a radial direction of the body 11, and each water channel rib 1102 may extend in a circumferential direction of the body 11. The plurality of waterway slots 103 may be formed by the body 11 and the plurality of waterway ribs 1102 in cooperation. Wherein each waterway rib 1102 may extend obliquely outward with respect to the axial direction of the body 11 and toward the inside of the annular hole 1110 of the body 11.

Therefore, the water channel groove 103 can be obliquely arranged relative to the axial direction of the body 11, the oblique water channel groove 103 has a flow guiding effect on water, water can enter the cavity 101 more quickly under the action of centrifugal force when the water is injected into the body 11, and the water can flow out more quickly under the action of gravity when the body 11 discharges water outwards, so that the water inlet and discharge efficiency can be improved.

As shown in fig. 3 and 4, the body 11 may include a plurality of tiles 1104, and the plurality of tiles 1104 are individually molded. That is, each tile 1104 is a separate molded tile. The plurality of splicing blocks 1104 are sequentially connected end to end along the circumferential direction of the body 11. Each channel rib 1102 is formed by sequentially connecting a plurality of rib segments 1103 arranged on a plurality of splicing blocks 1104 in an end-to-end manner. That is to say, each water channel rib 1102 comprises a plurality of rib segments 1103 and the plurality of rib segments 1103 are arranged on the plurality of splicing blocks 1103 in a one-to-one correspondence manner, and meanwhile, each splicing block 1103 is further provided with a plurality of rib segments 1103 and the plurality of rib segments 1103 respectively belong to the plurality of water channel ribs 1102 in a one-to-one correspondence manner.

Therefore, during manufacturing, the plurality of splicing blocks 1104 can be formed firstly, then the plurality of splicing blocks 1104 are connected together, and compared with the integrally formed structure of the plurality of splicing blocks 1104, the split forming structure is more easily subjected to mold stripping, the influence on the shape of a formed part can be reduced during mold stripping, the shape retentivity is good, the size of a single forming part can be reduced, the cost of a mold is reduced, the production is more convenient, and the mass production is facilitated.

The present invention is not particularly limited as to how the channel ribs 1102 and the body 11 are specifically fitted to form the plurality of channel grooves 103. Alternatively, according to some embodiments of the present invention, the two side walls of any one of the channel slots 103 may be respectively formed by two adjacent channel ribs 1102. That is, any one of the waterway grooves 103 is located between two adjacent waterway ribs 1102, as shown in fig. 3, for example. The structure is more regular, and the consistency of the water channel grooves 103 is better.

In other embodiments of the present invention, among the plurality of water channel grooves 103, the two side wall of the water channel groove 103 located at the outer side are respectively formed by the water channel rib 1102 and the body 11, that is, the water channel groove 103 located at the outer side is located between the water channel rib 1102 and the body 11, for example, as shown in fig. 1, a balance ring.

Of course, in some embodiments of the present invention, which are not shown, it is also possible to make both side walls of the inner channel groove 103 be respectively formed by the channel rib 1102 and the body 11, or to make both side walls of the outer channel groove 103 and both side walls of the inner channel groove 103 be formed by the body 11 and the channel rib 1102. That is, in the embodiment of the present invention, among the plurality of water channel grooves 103, both side groove walls of the water channel groove 103 located at the outer side and/or the inner side may be respectively formed of the water channel rib 1102 and the body 11. This can reduce the number of the water channel ribs 1102, and is more convenient for demolding.

Alternatively, as shown in fig. 1, according to some embodiments of the present invention, the inclination angle of the waterway rib 1102 with respect to the axial direction of the body 11 may be γ, and γ may satisfy: gamma is more than 0 degree and less than or equal to 60 degrees. When the balance ring 1 satisfies this condition, not only more do benefit to the shaping, the demolding is more smooth and easy, and the water guide is effectual moreover, can promote into water and drainage, and is blockier to the response speed of balance adjustment, and the regulating effect is better, is favorable to reducing the vibration of clothing treatment facility 1000. For example, in some specific examples of the invention, γ is 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, etc., respectively.

Alternatively, the inclination degrees of the plurality of waterway ribs 1102 may be the same or different. Alternatively, according to some embodiments of the present invention, a plurality of the waterway ribs 1102 may be arranged in parallel. Thus, not only is the width of the water channel groove 103 more uniform, the water flow more stable, but also the manufacture is easier.

As shown in fig. 1 to 3, in some embodiments of the present invention, the axially outer end faces of the plurality of water passage ribs 1102 may be flush with each other, and the axially outer end faces of the plurality of water passage ribs 1102 may be located in a plane perpendicular to the axial direction of the body 11. Therefore, the structure of the balance ring 1 is more regular, and the forming and demolding performance is better.

Referring to fig. 3 to 14, the plurality of tiles 1104 extend in the same length in the circumferential direction of the body 11. Therefore, the balance ring is more convenient to manufacture, the splicing effect of the balance ring 1 is better, and the whole structure is more stable.

Alternatively, as shown in fig. 4 to 9, two circumferential end surfaces of each of the tiles 1104 are planes respectively located in the axial section of the body 11. That is, the two circumferential end surfaces of each tile 1104 are each a plane, and the extension of the plane may pass through the central axis of the body 11. Thus, the splicing line of the two splicing blocks 1104 can be positioned in the radial direction of the body 11, the splicing gap is smaller, and the connection operation is more convenient.

According to some embodiments of the present invention, as shown with reference to fig. 3 to 14, the body 11 may include a first individual molding member 110 and a second individual molding member 120, the first individual molding member 110 and the second individual molding member 120 being respectively ring-shaped. The first individual molded article 110 includes the above-described plurality of tiles 1104, that is, the first individual molded article 110 is mainly composed of the plurality of tiles 1104. The first separate molding member 110 and the second separate molding member 120 may be axially connected, i.e., an axially inner end of the first separate molding member 110 and an axially outer end of the second molding member 120 may be connected together. Also, the first and second

separate molding pieces

110 and 120 may cooperate to form a plurality of chambers 101. Therefore, the balance ring 1 can be divided into more parts for molding, the mold size is smaller, the manufacturing efficiency is higher, and meanwhile, the splicing blocks 1104 can be axially positioned through the second single molding piece 120, so that the manufacturing error of the body 11 is smaller.

In some embodiments, the first individual molding member 110 and the second individual molding member 120 may be fusion-joined, that is, the first individual molding member 110 and the second individual molding member 120 may be axially fusion-joined. This not only facilitates the operation, but also ensures the connection between the first and second

separate molding members
