A laundry treating apparatus 1000 and a balance ring 1 according to an embodiment of the present invention will be described with reference to fig. 1 to 9.

Referring to fig. 1, 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. 1, 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 illustrated with reference to fig. 1-5, 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 balance ring assembly 10 is positioned in the outer barrel cavity 310 of the outer barrel 30, the balance ring assembly 10 comprises a balance ring 1 and a water injection part 2, and the balance ring 1 is connected with the inner barrel 20 to rotate along with the inner barrel 20.

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. When the front and rear two balance rings are provided, the structures of the two balance rings may be the same or different.

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.

Optionally, 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 1 will be further described below.

Referring to fig. 2 to 6, in some embodiments of the present invention, the balancing ring 1 may include an annular body 11, the body 11 has a chamber 101 therein, the body 11 has a water inlet 102, the water inlet 102 extends along a circumferential direction of the body 11, and in some embodiments, the water inlet 102 is an annular opening formed in the body 11, so that when the balancing ring 1 rotates, the water filling member 2 can fill the chamber 101 through the annular water inlet 102, and water entering the chamber 101 may be gathered at an outer wall surface of the chamber 101 under the action of centrifugal force and may not 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.

In the embodiment shown in fig. 2 to 6, 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. 3 to 8, the body 11 may be provided with three water passage grooves 103, the three water passage grooves 103 respectively extending along the circumferential direction of the body 11, and in some embodiments, the water passage 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 the axial 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 passage groove 103 to feed water into the chamber 101 through the water passage groove 103.

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.

Referring to fig. 1 to 9, in some embodiments of the present invention, the body 11 is provided with a plurality of water passage grooves 103, and for convenience of description, the water passage groove 103 located outermost in the axial direction of the body 11 is referred to as a first water passage groove 113, and the water passage groove 103 located innermost in the axial direction of the body 11 is referred to as a second water passage groove 123. In some embodiments of the present invention, the notch of the second water channel groove 123 is provided on the outer side of the second water channel groove 123 in the axial direction (i.e., axial direction) of the body 11. In other embodiments of the present invention, the notch of the first water channel groove 113 is provided on the outer side of the first water channel groove 113 in the axial direction of the body 11.

For example, in the embodiment shown in fig. 2 to 6, the notch of the second water channel groove 123 is disposed on the outer side groove wall of the second water channel groove 123 in the axial direction of the body 11, at this time, the second water channel groove 123 may form an axial water inlet structure, and at this time, the degree of the water injection port of the water injection member 2 injecting water into the second water channel groove 123 extending inward in the axial direction may be reduced, which is beneficial to reducing the length of the water injection member 2.

In the embodiment shown in fig. 7 to 9, the notch of the first water channel groove 113 is provided on the outer groove wall of the first water channel groove 113 in the axial direction of the body 11, in which case the outer groove wall is located on the axially outer side of the body 11 and is also the axially outer end surface of the body 11, and the first water channel groove 113 is formed in an axial water inlet structure, in which case the water injection port of the water injection member for injecting water into the first water channel groove 113 may not be inserted into the annular hole of the balance ring 1.

Researches show that the water channel groove 103 with the axial water inlet structure has better water inlet and outlet effects and good balance adjusting effect, can reduce the vibration of the clothes treatment equipment to a greater extent, is favorable for saving the internal space of the clothes treatment equipment 1000, can improve the cylinder capacity of the inner cylinder 20, and is especially favorable for increasing the volume of the cylinder opening of the inner cylinder 20; when the inner cylinder 20 is not processed to increase the volume, the distance between the balance ring 1 and the adjacent component is relatively large, so that the mutual interference can be reduced, the assembly performance and the operation performance are improved, the vibration is further reduced, the requirement on the shape of the inner cylinder 20 is favorably reduced by increasing the space, and the inner cylinder 20 is easier to manufacture.

It is understood that the structure of the second water channel groove 123 shown in fig. 2 to 6 and the structure of the first water channel groove 113 shown in fig. 7 to 9 may also be used in the same embodiment, as needed. That is, in some alternative embodiments of the present invention, either or both of "the notch of the second water channel groove 123 is disposed on the outer side of the second water channel groove 123 in the axial direction (i.e., the axial direction) of the body 11" and "the notch of the first water channel groove 113 is disposed on the outer side of the first water channel groove 113 in the axial direction of the body 11" may be satisfied.

According to some embodiments of the present invention, the body 11 includes a main body 1101 and a plurality of water channel ribs 1102, the plurality of water channel ribs 1102 being connected to the main body 1101. The main body 1101 is provided with a cavity 101 therein, and each water channel groove 103 is formed by two adjacent water channel ribs 1102 matched with the main body 1101. Optionally, in some embodiments of the present invention, at least a portion of a cross section taken along the axial cross section of the body 11 of the at least one waterway rib 1102 forming the first waterway groove 113 extends obliquely outward with respect to the axial direction of the main body portion 1101 and inward with respect to the radial direction of the main body portion 1101. In other embodiments of the present invention, at least a portion of a cross section taken along the axial cross section of the body 11 of the at least one waterway rib 1102 forming the second waterway groove 123 extends obliquely outward with respect to the axial direction of the main body portion 1101 and inward with respect to the radial direction of the main body portion 1101.

For example, in some examples of the present invention, as in the embodiment shown in fig. 3 to 6, at least a part of a cross section of the second water channel groove 123, which is formed by cutting the water channel rib 1102 of the second water channel groove 123 on the axially inner side of the body 11 along the axial cross section of the body 11, may extend obliquely outward with respect to the axial direction of the main body portion 1101 and inward with respect to the radial direction of the main body portion 1101, that is, at least a part of the cross section extends obliquely outward with respect to the axial direction of the body 11 and inward of the annular hole 1110 of the body 11. In other specific examples of the present invention, the first water channel groove 113 may also 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.

Studies have shown that, when the first and second water channel grooves 113 and 123 are formed with the inclined portions, not only is the increase in volume of the inner tube 20 facilitated, but also the molding is more convenient.

The structure of the water channel 103 will be further described below with reference to some embodiments.

Referring to fig. 2 to 6, in some embodiments of the present invention, the notch section 1231 of the second water channel groove 123, which is cut along the axial section of the body 11, may be formed to extend obliquely outward with respect to the axial direction of the body 11 and inward with respect to the radial direction of the body 11. In this way, not only is the manufacturing more convenient, but also the notch of the second water channel groove 123 can be oriented towards the axial direction of the body 11, so that the space occupation of the balance ring 1 in the radial direction can be reduced, and the volume of the inner barrel 20 can be further increased, that is, the barrel capacity of the inner barrel 20 can be increased.

It is to be understood that, although in this embodiment, only the notch sections 1231 are provided to be inclined, the second waterway groove 123 may be entirely provided to be inclined, that is, in this embodiment of the present invention, at least the notch sections 1231 of the second waterway groove 123 may be inclined to extend outwardly with respect to the axial direction of the body 11 and toward the inside of the annular hole 1110 of the body 11.

As shown in fig. 6, an inner groove wall of the second water passage groove 123 in the axial direction of the body 11 may be disposed obliquely with respect to the axial direction of the body 11, where the inner groove wall of the second water passage groove 123 is a water passage rib 1102 located inside the second water passage groove 123 in the axial direction of the body 11. The inclined axial inner wall has a flow guiding effect on water, and the area of the water inlet is relatively large, so that water inlet and water discharge are facilitated, and the installation of the parts such as the water injection piece 2 and the like adjacent to the water inlet is facilitated.

As shown in fig. 6, the inclined portion of the waterway rib 1102 may have an inclination angle γ 0 with respect to the axial direction of the body 11, and γ 0 may satisfy: gamma 0 is more than or equal to 30 degrees and less than or equal to 60 degrees. Like this, the degree of inclination of notch section 1231 is comparatively moderate, not only is convenient for make, and is better to the water conservancy diversion effect moreover. For example, in some specific examples of the invention, γ 0 is 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, etc., respectively.

As shown in fig. 6, a flange 1230 extending outward along the axial direction of the body 11 may be disposed at the front edge of the water channel rib 1102 located inside the second water channel groove 123 along the axial direction of the body 11, when water is injected into the second water channel groove 123 from the notch, the flange 1230 may have a certain water retaining and guiding effect, which may not only reduce the direct inward splash of water into the ring hole 1110, but also promote the water flowing out into the second water channel groove 123, thereby improving the water inlet effect, reducing the water loss, and at the same time, the flange 1230 may also increase the strength of the body 11, so that the structure of the balance ring 1 is more stable and reliable.

In the embodiment shown in fig. 3 to 6, in addition to the second water channel groove 123, a section taken along an axial section of the body 11 by the other water channel grooves 103 provided on the inner circumferential surface of the body 11 may extend in a direction perpendicular to the axial direction of the body 11, that is, in a radial direction of the body 11. Therefore, the other water channel grooves 103 can form a radial water inlet structure, which is more beneficial to utilizing the action of centrifugal force and gravity and can promote water inlet and water discharge. This compensating ring 1 can have these two kinds of water directions of intaking of axial and radial, and it is effectual to intake, not only makes the structure of compensating ring 1 compacter, more is favorable to making the structure of water injection spare 2 become compacter and small and exquisite moreover, can further do benefit to the volume that increases inner tube 20.

Referring to fig. 6, the second water channel groove 123 may include a notch section 1231 and a water passing groove section 1232, the water passing groove section 1232 may be used to communicate the notch section 1231 with the chamber 101, and a section formed by cutting the water passing groove section 1232 along an axial section of the body 11 may extend in a direction perpendicular to an axial direction of the body 11, that is, in a radial direction of the body 11, so that it is more advantageous to utilize the action of centrifugal force and gravity, and water inlet and water discharge may be facilitated. Meanwhile, the second water channel groove 123 can axially feed water and then change the direction to flow to the chamber 101 along the radial direction, and the water flow can become more stable before flowing to the chamber 101, which is beneficial to more uniform distribution of water in the chamber 101.

When the other water channel grooves 103 also extend along the radial direction of the body 11, the structure of the second water channel groove 123 is more matched with the radial water inlet structure of the other water channel grooves 103, which is beneficial to reducing the unbalanced impact on the body 11 when the chamber 101 is filled with water, so that the stress of the balance ring 1 is more uniform when the water is filled, and the balance of the balance ring 1 is better.

The first water channel groove 113 will be further described with reference to the embodiments shown in fig. 7 to 9. Referring to fig. 7 to 9, the first water channel groove 113 may be provided at an axially outer end surface of the body 11, and the remaining water channel grooves 103 may be provided at a radially inner end surface of the body 11. Accordingly, the first water channel grooves 113 are moved to the axial end surface of the body 11, and the number of the water channel grooves 103 on the inner circumferential surface of the body 11 can be reduced, so that the positions of the water channel grooves 103 located on the axial inner side can be moved outward, which is advantageous for vacating the positions of the axial inner ends of the radial inner side of the body 11, and thus the installation space of the inner cylinder 20 can be increased.

Further, the first water channel groove 113 may extend in an axial direction of the body 11, and the remaining water channel grooves 103 extend perpendicular to the axial direction of the body 11, that is, the extending direction of the remaining water channel grooves 103 is perpendicular to the axial direction of the body 11, that is, the remaining water channel grooves 103 extend in a radial direction of the body 11. Therefore, the manufacturing is more convenient, and the effect of thinning the body 11 is better.

According to some embodiments of the present invention, still referring to the embodiments shown in fig. 2 to 6, the axial front end of the inner cylinder 20 may be provided with the balance ring 1, the front portion of the inner cylinder 20 has a cylinder opening portion 230, and the cylinder opening portion 230 extends into the ring hole 1110 of the balance ring 1. At least a portion of the barrel portion 230 can extend obliquely forwardly and inwardly relative to the axial direction of the inner barrel 20. Here, "inwardly" is the direction into the annular ring 1110 of the body 11. Therefore, the inclined cylinder opening part 230 can not only increase the volume of the inner cylinder 20, but also reduce the molding difficulty and facilitate molding and manufacturing; in addition, for some clothes treating apparatuses that introduce air into the inner tub 20, such an arrangement also has an air guiding effect.

Further, as shown with reference to fig. 2 to 6, the port portion 230 may include a first port section 231 and a second port section 232, the first port section 231 extends in an axial direction of the inner tube 20, the second port section 232 is connected to a rear portion of the first port section 231, and the second port section 232 may extend obliquely forward and inward with respect to the axial direction of the inner tube 20. Alternatively, the projection of the second water channel groove 123 in the radial direction of the body 11 may be located within the projection of the second port section 232 in the radial direction of the body 11.

Therefore, the tube opening part 230 is in a partially inclined state, the front end outlet is approximately in an axial direction, the sealing is facilitated, the rear end can be in an inclined state, the forming is facilitated, and further, the tube opening part 230 in the inclined state is matched with the structure of the water channel groove 103, the assembly is facilitated, and the interference between the balance ring 1 and the inner tube 20 is reduced. Alternatively, the second mouth end 232 may extend in a single inclined degree as a whole, or may be divided into a plurality of sections extending in a plurality of inclined degrees.

Optionally, as shown in fig. 6, the front end of the first opening end 231 may be provided with an outward bent flange, which not only can increase strength, but also makes the structure smoother, and meanwhile, is favorable for being matched with a door sealing ring to achieve better sealing.

As shown in fig. 6, the inner groove wall of the second water channel groove 123 in the axial direction of the body 11 may be spaced from the second port section 232 by a distance M, which may satisfy: m is more than or equal to 1mm and less than or equal to 5 mm. When the value of M is within the above range, the interference between the inner drum 20 and the balance ring 1 can be reduced well, the waste of space is reduced, and the transmission of the vibration of the balance ring 1 generated under the impact of water to the inner drum 20 can also be reduced, so that the vibration of the laundry treating apparatus 1000 is smaller, and the operation is more stable.

Other configurations and operations of the laundry treating apparatus according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.
