In the description of the present invention, it is to be understood that the terms "central," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present invention and for simplicity in description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and are not to be construed as limiting the present invention. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

A laundry treating apparatus 1000 according to an embodiment of the present invention is described below with reference to fig. 1 to 36.

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. 2, 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 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. 2 to 6, the water injection member 2 may be installed on the outer cylinder 30, and the water injection member 2 may be stationary when the inner cylinder 20 rotates the balance ring 1, which not only facilitates manufacturing and installation, but also enables more stable water injection. The structure of the water injection member 2 will be described in detail later, and the structure of the balance ring 1 will be further described below.

Referring to fig. 7 to 12, in some embodiments of the present invention, the balancing ring 1 includes an annular body 11, the body 11 has a chamber 101 therein, an inner circumferential surface of the body 11 has a water inlet 102, and the water inlet 102 extends along a circumferential direction of the body 11, that is, the water inlet 102 is an annular opening provided on the inner circumferential surface of the body 11. Therefore, when the balance ring 1 rotates, the water injection piece 2 can conveniently inject water into the chamber 101 through the annular water inlet 102, 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.

it will be appreciated that the chamber 101 in the balance ring 1 may be arranged in different configurations to achieve the effect of adjusting the load eccentricity by water injection. The structure of the gimbal 1 is further described below with reference to some embodiments.

Fig. 7 to 12 show a gimbal 1 according to a first embodiment of the present invention. As shown in fig. 7 to 12, 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.

As shown with continued reference to fig. 7 to 12, the inner circumferential surface of the body 11 may be provided with three water passage grooves 103, the three water passage grooves 103 extending in the circumferential direction of the body 11 and arranged in the axial direction of the body 11, respectively. The three water passage grooves 103 are in one-to-one correspondence with the three chambers 101, and the bottom wall surface 1031 of each water passage groove 103 has three openings 104 to communicate the water passage groove 103 with the corresponding chamber 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.

according to some embodiments 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 and manufacturing process. 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.

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 passage groove 103 is communicated with all the chambers 101, and the size of the opening 104 of each water passage groove 103 communicated with the plurality of chambers 101 is different, so that the water passage groove 103 can inject different amounts of water into the plurality of chambers 101, respectively, thereby achieving the adjustment of the balance.

In this regard, for convenience of description, referring to fig. 9 to 12 as an example, the channel grooves 103 are three, respectively a first channel groove 113, a second channel groove 123 and a third channel groove 133, and the chambers 101 are three, respectively a first chamber 111, a second chamber 121 and a third chamber 131, and the size of the opening 104 of the first channel groove 113 for communicating with the first chamber 111 may be set large and the size of the opening 104 for communicating with the second chamber 121 and the third chamber 131 may be set small, the size of the opening 104 of the second channel groove 123 for communicating with the second chamber 121 may be set large and the size of the opening 104 for communicating with the first chamber 111 and the third chamber 131 may be set small, and the size of the opening 104 of the third channel groove 133 for communicating with the third chamber 131 may be set large and the size of the opening 104 for communicating with the first chamber 111 and the second chamber 121 may be set small.

thus, when water injection into one of the chambers 101 is mainly required, water injection into the corresponding water channel groove 103 having a large amount of injected water can be controlled, and for example, when water injection into the first chamber 111 is mainly required, water injection into the first water channel groove 113 can be controlled.

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.

In addition, in the embodiment shown in fig. 7 to 12, the plurality of chambers 101 may be completely staggered in the circumferential direction of the body 11, that is, any two chambers 101 do not have an overlapping portion in the circumferential direction of the body 11, in other words, there are no two chambers 101 at any position in the circumferential direction of the body 11, and there is only one chamber 101 if there is. Therefore, the balance adjusting effect can be improved.

Of course, the present invention is not limited to this, and the plurality of chambers 101 may also be arranged along the circumferential portion of the body 11 in a staggered manner, that is, two adjacent chambers 101 may extend to the same position in the circumferential direction of the body 11, and at the same time, the two adjacent chambers 101 also extend to different positions in the circumferential direction of the body 11.

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 circumferentially extending water channel grooves 103 are arranged on the inner circumferential surface of 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 of the weight of the balance ring 1 along the circumferential direction can be realized, the centering of the load is realized, and the balance adjustment is finally realized.

As shown in fig. 10 to 12, three openings 104, through which the water passage groove 103 communicates with each chamber 101, may be provided at intervals in the circumferential direction of the body 11, so that water inflow is smoother and more uniform. It is understood that the number of the openings 104 of the water channel 103 communicating with each chamber 101 is not limited to three, and may be other numbers, such as one, two, four, etc., and may be flexibly set according to actual needs.

With continued reference to fig. 10-12, the three chambers 101 may be of the same volume and shape, which not only facilitates manufacturing, but also makes balancing adjustments easier. According to some embodiments of the present invention, when the number of chambers 101 is other, the plurality of chambers 101 may still be configured to have the same volume and the same shape. Of course, the present invention is not limited thereto, and the plurality of chambers 101 may be provided to have different volumes and shapes as needed.

alternatively, according to some embodiments of the present invention, the depth direction of each water channel groove 103 and the orientation of the notch (i.e., the water inlet 102) of each water channel groove 103 are perpendicular to the axial direction of the body 11. That is, the direction of the groove bottom wall surface 1031 of the water passage groove 103 toward the groove bottom is substantially the extending direction of the radial section of the body 11, and the direction of the groove bottom is also substantially the extending direction of the radial section of the body 11, so that the direction of the groove bottom wall surface 1031 of the water passage groove 103 toward the groove bottom is substantially directly opposite to the center of the body 11, which not only makes it easier for water to enter the groove bottom, but also makes it possible for water to enter the chamber 101 more quickly and smoothly through the water passage groove 103, further improving the regulation efficiency.

Fig. 13 to 15 show a gimbal 1 according to a second embodiment of the present invention. The structure in this embodiment is substantially the same as that in the first embodiment, and the difference is mainly in the structure of the notch of the water passage groove 103. As shown in fig. 13 to 15, the water blocking rib 105 may be disposed at an edge of the notch (i.e., the water inlet 102), so that water may splash to some extent when being sprayed onto the inner wall surface of the body 11, and the water blocking rib 105 may effectively reduce splashing, so that water sprayed from the water injection member 2 is not easy to splash, and the water injection efficiency is improved.

The specific structure of the water retaining rib 105 is not particularly limited, and the water retaining rib can meet the requirement of forming a certain inhibition effect on the splashing of water. Alternatively, taking the embodiment shown in fig. 14 as an example, the water blocking rib 105 may be disposed such that the notch is substantially formed as a necking structure, and water entering the notch may be blocked by the water blocking rib 105 and is not prone to splash outwards. Optionally, in this embodiment, the water blocking rib 105 is a flange extending from the edge of the notch to the inside of the notch along the axial direction of the body 11, so that the structure is not only convenient to manufacture, and the appearance is more regular and beautiful, but also the splashing prevention effect is better.

Of course, the water blocking rib 105 may also be a flange extending into the notch in an axial direction inclined to the body 11, and the flange may extend along a straight line or a curved line. Alternatively, as shown in fig. 19, the water blocking rib 105 may be provided as a protrusion provided at the edge of the notch, and this structure may also play a role of splash prevention.

In addition, in order to eliminate the splash and reduce the influence on the inflow water, the protruding dimension of the water blocking rib 105 in the groove is not likely to be too large, and for example, the protruding dimension may be set within 3mm, for example, 1mm or 2 mm.

Optionally, the water blocking rib 105 may be an integral piece with the body 11, or may be a separate piece assembled with the body 11, and the water blocking rib 105 may be flexibly disposed according to actual conditions.

As shown in fig. 19, in some embodiments of the present invention, the depth h of the water channel groove 103 may be set to 5mm or more. The arrangement ensures the sufficient depth of the water channel groove and also plays a role in preventing splashing.

fig. 16 to 20 show a gimbal 1 according to a third embodiment of the present invention. The structure in this embodiment is substantially the same as that in the second embodiment, and the difference is mainly in the structure of the inner wall surface of the chamber 101. In short, the present embodiment optimizes the structure of the chamber 101, and the chamber 101 is chamfered at the corners to make the water in the balance ring 1 easier to drain, and to make the flocks entering the balance ring 1 during the washing process easier to drain.

As shown in fig. 16, 17, and 19, alternatively, the chamber 101 is formed with an axial-end inside angle 106 between the inner wall surfaces of both ends of the chamber 101 in the axial direction of the body 11 and the inner wall surface of the inner end of the chamber 101 in the radial direction of the body 11, that is, an angle formed at the junction of the chamber side wall surface 1011 of the chamber 101 and the chamber bottom wall surface 1012 of the chamber 101 is the axial-end inside angle 106. Optionally, the axial end inside corners 106 of both ends of the cavity 101 are chamfered. This configuration may weaken the dead corner area within the chamber 101, avoid the accumulation of lint, and make the inner wall surface of the chamber 101 smoother, thereby facilitating the drainage of water and debris.

it is understood that both axial end inside corners 106 of the cavity 101 may be chamfered at the same time, or only one of them may be chamfered, that is, in the embodiment of the present invention, the axial end inside corner 106 formed by the cavity 101 between the inner wall surface of at least one end in the axial direction of the body 11 and the inner wall surface of the inner end of the cavity 101 in the radial direction of the body 11 may be chamfered.

Further, the axial end inside corner 106 may be further rounded. This can further eliminate the dead corner region, and thus the interior of the chamber 101 can be made smoother, and drainage of water, lint, and the like can be facilitated.

alternatively, as shown in fig. 17, 18, and 20, a circumferential end-inside angle 107 is formed between the inner wall surfaces of both ends of the chamber 101 in the circumferential direction of the body 11 and the inner wall surface of the inner end of the chamber 101 in the radial direction of the body 11, that is, an angle formed at the junction of the chamber end wall surface 1013 of the chamber 101 and the chamber bottom wall surface 1012 of the chamber 101 is the circumferential end-inside angle 107. Alternatively, the circumferential end inside corners 107 of both ends of the cavity 101 may be chamfered. This also reduces the dead space within the chamber 101 and facilitates the removal of water and debris.

It is understood that both circumferential end inside corners 107 of the cavity 101 may be chamfered at the same time, or only one of them may be chamfered, that is, in the embodiment of the present invention, the circumferential end inside corner 107 formed between the inner wall surface of at least one end of the cavity 101 in the circumferential direction of the body 11 and the inner wall surface of the inner end of the cavity 101 in the radial direction of the body 11 may be chamfered.

further alternatively, the circumferential end inside corner 107 may be a rounded corner. This can further eliminate the dead corner region, and thus the inside of the chamber 101 can be more smoothly formed, and the discharge of the water, the lint, and the like can be facilitated.

As shown in fig. 20, optionally, the compartment wall 108 separating two adjacent compartments 101 is provided with a closed cavity 1081 at the inner end in the radial direction of the body 11. In other words, adjacent compartments 101 may be separated by a compartment wall 108, the side of the compartment wall 108 facing into the compartment 101 constituting a compartment end wall surface 1013 of the compartment 101. Optionally, the inner end of the compartment wall 108 is provided with a closed cavity 1081 in the radial direction of the body 11, so that the material consumption can be reduced and the cost can be reduced while the chamfer is provided. Optionally, the width of the closed cavity 1081 may decrease from inside to outside along the radial direction of the body 11, and therefore, the closed cavity 1081 may be formed in a substantially triangular shape, and is more matched with the chamfer structure, so that the structural design is more reasonable, and the manufacturing is facilitated.

In embodiments with closed cavities 1081, each compartment wall 108 may have a closed cavity 1081, or some of the compartment walls 108 may have a closed cavity 1081, for example, in the embodiment shown in fig. 18, three compartment walls 108 are provided, two of the compartment walls 108 having a closed cavity 1081, and the other compartment wall 108 having a solid structure.

in some embodiments of the present invention, the body 11 may be an integral component, in which case, the compartment wall 108 is integrally formed on the body 11, so that the overall structural strength is high, the sealing performance is good, and the deviation of the position or size of the compartment 101 caused by the assembly error in the later period can be reduced. Of course, the body 11 may also be a fitting, for example, in other embodiments of the present invention, the body 11 is composed of a main portion and a partition plate, the partition plate may be fitted in the body 11 to partition a plurality of chambers 101, and the partition plate may constitute the partition wall 108, wherein the connection point of the partition plate and the main portion may be arc-shaped to form the arc-shaped angle.

Fig. 21 to 24 show a gimbal 1 according to a fourth embodiment of the present invention. The structure in this embodiment is substantially the same as that in the third embodiment, and the difference is mainly in the internal structure of the chamber 101. The structure in this embodiment can improve the operation stability of the clothes treatment device.

specifically, referring to fig. 21-24, optionally, at least one partition wall 109 is provided within the chamber 101 to partition the chamber 101 into a plurality of subcavities 1010 distributed along the circumference of the body 11. That is, the chamber 101 may be provided with the partition walls 109, the partition walls 109 may divide the chamber 101 into a plurality of sub-chambers 1010, and the partition walls 109 may be correspondingly arranged according to the required number of the sub-chambers 1010, for example, in fig. 24, for each chamber 101, there are three sub-chambers 1010 and two partition walls 109. When there are two sub-chambers 1010, a partition wall 109 may be provided in the chamber 101. A plurality of sub-chambers 1010 may be distributed along the circumferential direction of the body 11, and adjacent two sub-chambers 1010 may communicate with each other through the communication port 1091 of the partition wall 109, so that adjacent two sub-chambers 1010 may achieve the flow of water with each other through the communication port 1091.

Considering that when the balance ring 1 moves at a high speed, the water in the chamber 101 is easily gathered at one end of the chamber 101 due to the gravity and the centrifugal force, and is easily vibrated. Such a structural design as described above can partition the inside of the chamber 101, and the water in the chamber 101 can flow among the plurality of sub-chambers 1010, so that the water distribution inside the chamber 101 is more uniform, resulting in a more stable operation of the laundry treating apparatus 1000, for example, a more stable dehydration process, and vibration and noise can be reduced.

The number, shape, distribution position and the like of the communication ports 1091 are not particularly limited, and taking the structure shown in fig. 22 as an example, two communication ports 1091 may be provided, and the two communication ports 1091 are respectively provided at both ends in the radial direction of the partition wall 109, so that the adjustment effect is good. As shown in fig. 22, the communication port 1091 may be a substantially elongated hole to facilitate the passage of water, and the corners of the communication port 1091 may be rounded. Therefore, the uniformity of water distribution can be further improved, and the balance effect is more obvious.

Alternatively, the partition wall 109 may be constituted by a partition plate provided in the chamber 101, or the partition wall 109 may be integral with the body 11, and may be flexibly provided depending on the actual situation. In addition, in order to improve the overall strength and stability of the gimbal 1, a rib 12 may be provided on the body 11, as shown in fig. 21. The specific structure of the reinforcing ribs 12 is not particularly limited, and for example, as shown in fig. 21, the reinforcing ribs 12 may be arranged so as to extend in the radial direction of the body 11 and be distributed in the circumferential direction.

according to some embodiments of the present invention, the balance ring 1 may be used singly or in pairs. For example, as shown in fig. 2 and 5, 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 both 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.

Fig. 25 and 26 show two arrangements of the gimbal 1, both of which enable control of the balancing. For convenience of description, it is assumed that the two balance rings 1 are the first balance ring 110 and the second balance ring 120, respectively. In the embodiment shown in fig. 25, the chambers 101 of the two balancing rings 1 corresponding to each other are aligned with each other in the circumferential direction of the inner cylinder 20, i.e. the first chamber 111 of the first balancing ring 110 is aligned with the first chamber 111 of the second balancing ring 120 in a front-to-back manner, and when the projections of the two chambers 101 along the axial direction of the balancing rings 1 coincide with each other, the second chamber 121 and the third chamber 131 are also aligned with each other, respectively.

in the embodiment shown in fig. 26, the two balancing rings 1 have the same number of chambers 101 corresponding to one another, and optionally, the chambers 101 of the two balancing rings 1 corresponding to one another are arranged offset in the circumferential direction of the inner cylinder 20 by an angle of 180 degrees, that is, one balancing ring 1 is mounted rotated by 180 degrees with respect to the other balancing ring 1. At this time, alternatively, in the embodiment shown in fig. 27, when the chambers 101 are three, one chamber 101 of one balance ring 1 may correspond to the other two chambers 101 of the other balance ring 1, for example, the first chamber 111 of the first balance ring 110 may correspond to the second chamber 121 and the third chamber 131 of the second balance ring 120.

It should be noted that the above two configurations are described as examples, and the arrangement of the two balance rings 1 is not particularly limited. That is, in the embodiment of the present invention, the chambers 101 of the two balancing rings 1 corresponding to each other may be aligned with each other in the circumferential direction of the inner cylinder 20, or may be disposed in a staggered manner, where the staggered manner includes both a partial staggered manner and a complete staggered manner, and for example, the staggered angle may be 30 degrees, 45 degrees, 60 degrees, 75 degrees, 90 degrees, 120 degrees, or the like.

in some embodiments of the present invention, only one chamber 101 may be disposed in the balance ring 1, in this case, only one water channel groove 103 may be disposed, and the chamber 101 may be disposed on a part of the circumferential direction of the body 11, in this case, in order to achieve balance adjustment, a plurality of balance rings 1 may be disposed on the inner cylinder 20, for example, a plurality of balance rings 1 may be disposed at one axial end of the inner cylinder 20, and the chambers 101 of the plurality of balance rings 1 may be disposed in a staggered manner in the circumferential direction, so that balance adjustment of the processing cylinder apparatus 100 may also be achieved by adjusting the amount of water injected into each chamber 101.

in addition, when the balance ring 1 is provided in plural, for example, two, the water injection member 2 may be provided in plural so as to inject water to the plural balance rings 1, respectively. Of course, in some embodiments, the water injection member 2 may be provided as one, and the water injection member 2 may be provided to be movable so as to inject water to different balance rings 1.

As shown in fig. 1 to 3 and 27, according to some embodiments of the present invention, a water receiving plate 40 may be disposed in the outer cylindrical cavity 310, the water receiving plate 40 has a drain port 401, and the water receiving plate 40 is configured to receive water falling from an upper portion of the balance ring 1 and allow the water to flow from the drain port 401 to a bottom of the outer cylindrical cavity 310.

The structure of water receiving plate 40 can form into the multiple, refer to fig. 2, 3 and 27 and show, water receiving plate 40 can form into the arc that extends along the circumference of stabilizer ring 1, and the lower half of inboard at stabilizer ring 1 is established to the arc, and the circumference both ends of arc are all upwards not surpassed the central axis of stabilizer ring 1, that is to say, the height that highly all is not higher than the central axis of stabilizer ring 1 at the circumference both ends of arc. For example, they may be flush. Therefore, the space between the balance ring 1 and the inner cylinder 20 and the space between the balance ring and the outer cylinder 30 are more matched, the space utilization is more reasonable, the water receiving plate 40 is moderate in size and can receive most of water falling from the upper part of the balance ring 1, and the water receiving effect is better.

Alternatively, as shown in fig. 2, the axially outer end of the water receiving plate 40 may be connected to the side wall of the outer cylinder 30, the drain port 401 may be provided at the connection point, and the axially inner end of the water receiving plate 40 may be provided with a water blocking flange 41, as shown in fig. 2 and 27. The water retaining flange 41 can prevent water from dripping downwards from the axial inner end of the water receiving plate 40, so that water flows downwards from the sewer port 401, and the water receiving effect is improved.

Referring to fig. 2, according to some embodiments of the present invention, when there are two balance rings 1, the water receiving plate 40 may also be provided in two numbers, so that water flowing down from each balance ring 1 can be guided to the bottom of the outer cylinder chamber 310 through the water receiving plate 40. The specific structure of the water receiving plate 40 will be described in detail later, and will not be described in detail here.

The structure of the water injection member 2 will be further described with reference to the accompanying drawings.

referring to fig. 32 to 36, in some embodiments of the present invention, the water injection member 2 has a water injection port 201, the water injection port 201 is located in the annular hole 1110 of the balance ring 1, as shown in fig. 35, the outlet water flow of the water injection port 201 enters the cavity 101 of the balance ring 1 through the water inlet 102, and an angle α formed by a linear velocity V of the balance ring 1 at a falling point of the outlet water flow and an outlet direction (or water injection direction) L1 of the water injection port 201 is smaller than 90 °. Here, the linear velocity V is a direction extending in a tangential direction of the effluent water stream drop point Z and in the same direction as the rotation direction W of the gimbal 1.

Thereby, the water discharging direction may be inclined to a tangent line of the body 11 at the water discharging flow falling point Z and also to a straight line L2 extending in a radial direction of the body 11 passing through the water feeding point Z, and the water filling direction of the water filling member 2 approximately tends to balance the rotating direction W of the ring 1. When the water current jets into the balance ring 1, the reaction force of the inner wall surface of the balance ring 1 is small, the water sputtering is less, and the water is more favorably injected into the balance ring 1.

According to some embodiments of the invention, α may further satisfy: alpha is less than or equal to 30 degrees. Therefore, the water injection direction is closer to the tangential direction of the balance ring 1, the water injection effect can be further improved, and the water sputtering is further reduced. For example, in some specific examples of the invention, α is 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, etc., respectively.

As described above, in the embodiment of the present invention, there may be at least one water passage groove 103, and when there is one water passage groove 103, there may be one or more water injection ports 201; when there are a plurality of water channel grooves 103, the water injection ports 201 may also be provided as one or more, and at this time, when one water injection port 201 is provided, a portion of the water injection member 2 where the water injection port 201 is provided may be moved to realize water injection to different water channel grooves 103 through one water injection port 201.

Alternatively, as shown in fig. 34 to fig. 36, the number of the water injection ports 201 may be plural, for example, two, three, four, or the like, and the plural water injection ports 201 and the plural water passage grooves 103 may correspond to one another. Thus, the water injection is more conveniently controlled.

the present invention is not particularly limited with respect to the specific structure of the water injection member 2, and fig. 28 to 31, 32 to 36, and 37 to 40 show three structures of the water injection member 2, respectively. As shown in fig. 28 to 31, in some embodiments of the present invention, the water injector 2 may include a main housing 21, and the main housing 21 may have at least one water injection passage 203 therein, and an outlet of the water injection passage 203 is a water injection port 201. The water injection passage 203 and the water injection port 201 may be provided in plurality as needed. In this case, the water injection member 2 may be formed substantially as a single body, and thus, the installation is convenient.

Alternatively, as shown in fig. 31, when the water injection passage 203 is plural, the plural water injection passages 203 may be arranged side by side. The water route is more regular like this, and rivers are comparatively smooth and easy to, the thickness of water injection spare 2 can be less relatively, does benefit to and installs in the space between inner tube 20 and the compensating ring 1. The shape of the water injection channel 203 is not particularly limited, and may be a straight line or a broken line, and may be flexibly set as required.

According to some embodiments of the present invention, as shown in fig. 26 to 31 and 1 to 6, the water injection member 2 may be adjacently disposed at an inner side of the body 11, and the water injection member 2 may be integrally extended in an arc shape along a circumferential direction of the body 11. During the rotation of the inner cylinder 20, the water injection member 2 may be stationary, and at this time, a certain distance is kept between the water injection member 2 and the balance ring 1, and also between the water injection member and the inner cylinder 20. The arrangement enables the main housing 21 to be integrally formed into an arc shape, and the radial thickness of the water injection member 2 along the body 11 can be reduced, so that the space is saved, the space between the balance ring 1 and the inner drum 20 can be utilized best, the volume of the inner drum 20 can be increased, and the processing capacity of the clothes processing equipment 1000 can be increased.

In addition, in order to facilitate the installation of the water injection member 2, in the embodiment shown in fig. 28 to 31, a protruding installation plate may be provided at an end of the water injection member 2 away from the water injection port 201, and the installation plate is located outside the gap between the balance ring 1 and the inner cylinder 20, specifically, see the water injection member 2 located at the front side in fig. 5. Of course, the mounting plate is not essential and can be removed, in which case the connection to the other components is effected directly via the water injection member 2, for example, the water injection member 2 located on the rear side in fig. 5 is without a mounting plate.

In the balance ring assembly 10 of the embodiment shown in fig. 37 to 40, the water injection member 2 extends into the ring hole 1110 of the balance ring 1, and the water injection member 2 also extends integrally in an arc shape along the circumferential direction of the balance ring 1, so as to achieve the effect of saving space. It should be noted here that "extend into an arc shape along the circumferential direction of the balance ring 1 as a whole" is to be understood in a broad sense here, and it is understood that the water injection member 2 extends into an arc shape strictly according to the circumferential direction of the balance ring 1, and at this time, the water injection member 2 and the inner circumferential surface of the balance ring 1 may be arranged in parallel, and the size of the gap between the two is constant; it is of course also conceivable for the balancing ring 1 to extend in an arc-like manner approximately in the circumferential direction of the balancing ring 1, in which case the gap between the balancing ring 1 and the water injection piece 2 may vary slightly in the circumferential direction of the balancing ring 1.

Alternatively, the centre of the arc may be located on the centre axis of the balance ring 1, i.e. the water injection piece 2 is arranged coaxially with the balance ring 1, i.e. the centre axis of the water injection piece 2 coincides with the centre axis of the balance ring 1, e.g. the line L3 shown in fig. 37 is two coinciding centre axes. Therefore, the shapes of the water injection piece 2 and the balance ring 1 can be matched, and the installation and water injection performance can be improved. In addition, in some embodiments of the present invention, the central axis of the water injection member 2 may also coincide with the central axis of the tub 30 of the laundry treating apparatus 1000 for easier installation.

Furthermore, the inner circumferential surface of the water injection member 2, the outer circumferential surface of the water injection member 2 and the inner circumferential surface of the balance ring 1 are concentric cylindrical arc surfaces. Here, the outer peripheral surface of the water injection member 2 is an inner surface of the water injection member 2 facing the inner peripheral surface of the gimbal 1, and the inner peripheral surface of the water injection member 2 is an inner surface of the water injection member 2 facing the center of the gimbal 1. Therefore, the inner circumferential surface and the outer circumferential surface of the water injection piece 2 are parallel cambered surfaces, the water injection piece 2 can be formed into an arc-shaped plate-shaped structure with uniform thickness, the gap between the water injection piece 2 and the balance ring 1 can be basically kept unchanged in the circumferential direction and the axial direction of the balance ring 1, and the gap between the water injection piece 2 and the inner cylinder is also basically kept unchanged in the circumferential direction and the axial direction of the balance ring 1, so that the manufacturing is convenient, and the water injection effect is good.

according to some embodiments of the present invention, the central angle α 1 of the water injection member 2 satisfies: alpha 1 is more than or equal to 5 degrees and less than or equal to 30 degrees. Here, the central angle α 1 is an angle formed by connecting both ends of the water injection member 2 in the circumferential direction with the center of the water injection member 2, that is, a central angle corresponding to the arc-shaped extension length of the water injection member 2. In the embodiment shown in fig. 37, the water injection member 2 and the balance ring 1 are concentrically arranged, and the central angle α 1 is an angle formed by connecting the center of the balance ring 1 and the circumferential ends of the water injection member 2. Research shows that when the water injection part 2 meets the angle value requirement, the size of the water injection part 2 is more reasonable, the manufacturing is more facilitated, the product yield can be improved, and the water injection effect is more excellent. In some specific examples of the invention, the central angles α 1 are 10 degrees, 15 degrees, 20 degrees, 25 degrees, etc., respectively.

as described above, in the embodiment of the present invention, the balance ring 1 may have one water inlet 102, or may have a plurality of water inlets 102, when there is one water inlet 102, there may be one water injection port 201 of the water injection member 2, and when there are a plurality of water inlets 102, there may be a plurality of water injection ports 201 corresponding to the water inlets 102 one to one, so as to facilitate controlling water injection. In the embodiment shown in fig. 28 to 31, the water inlet 102 is plural, wherein the structure of the balancing ring 1 is substantially similar to that of the balancing ring 1 described in the previous embodiments, for example, as shown in fig. 39 and 40, the balancing ring 1 may include a plurality of circumferentially distributed chambers 101, the inner circumferential surface of the balancing ring 1 may be provided with a plurality of water passage grooves 103, and the like, and the specific structure of the balancing ring 1 may be referred to the description of the previous embodiments, and will not be described in detail herein.

as shown in fig. 40, the water injection ports 201 may include a plurality of, for example, three, and the plurality of water injection ports 201 may be spaced apart along the circumference of the balance ring 1 to correspond more to the positions of the plurality of circumferentially spaced water inlet ports 102 to further facilitate water injection. In the present embodiment, the internal structure of the water injector 2 is substantially similar to that shown in fig. 28 to 31, specifically, a plurality of water injection channels 203 arranged side by side may be provided in the water injector 2, the water injection channels 203 may be formed in an L shape and include a first channel section 2031 and a second channel section 2032, the first channel section 2031 extends in the axial direction of the balance ring 1, the second channel section 2032 extends in the circumferential direction of the balance ring 1, and an outlet of the second channel section 2032 is the water injection port 201. From this, the piece that annotates water can realize intaking and go out water from the direction of difference, more does benefit to the installation of each part to the waterway structure of buckling makes water filling port 201 play water more steady. Alternatively, the junction of the first channel section 2031 and the second channel section 2032 may be rounded to reduce water flow resistance.

referring to fig. 32 to 36, in other embodiments of the present invention, the water injection member 2 may include at least one nozzle 22, each nozzle 22 having a water injection passage 203 therein, an outlet of the water injection passage 203 being a water injection port 201. When a plurality of water injection passages 203 and water injection ports 201 are required, a corresponding number of nozzles 22 may be provided, and at this time, the water injection member 2 may be assembled by a plurality of nozzles 22. Alternatively, a plurality of nozzles 22 may be provided in a structure separable from each other to facilitate increasing or decreasing the number of the water injection ports 201.

Alternatively, as shown in fig. 34, when there are a plurality of nozzles 22, the plurality of nozzles 22 may be arranged side by side, the manufacture and installation are convenient, and the thickness of the water injection member 2 may be relatively small, facilitating installation into the space between the inner cylinder 20 and the balance ring 1. In addition, in the embodiment where the water injection member 2 includes the nozzle 22, the water injection member 2 may also extend in an arc shape along the circumferential direction of the body 11, so as to further achieve the effects of reducing the thickness and saving the space.

The position of the water injection member 2 in the circumferential direction of the balance ring 1 is not particularly limited in the present invention, and for example, as shown in fig. 2, the water injection member 2 may be provided inside the upper portion of the balance ring 1; for another example, the water injection member 2 may be provided inside the lower portion of the balance ring 1. When the water injection piece 2 is arranged on the inner side of the upper part of the balance ring 1, the water injection piece 2 can be prevented from being immersed by water of the clothes treatment equipment 1000 in a washing stage, flocks and the like are prevented from entering the water injection piece 2, and sealing is facilitated.

in the embodiment shown in fig. 32 to 37, the water injection member 2 is located at the lower portion of the balance ring 1, but the location of the water injection member 2 is not limited thereto, and may be flexibly located at different locations according to the actual situation, for example, in the embodiment shown in fig. 1 to 6, the water injection member 2 may be located at the upper portion of the balance ring 1. Research finds that the water injection piece 2 is better installed on the upper side than on the lower side.

in connection with the laundry treating apparatus 1000 according to some embodiments of the present invention, for example, as shown in fig. 1 to 6 and 37 to 40, the water injection member 2 is connected to the outer tub, the water injection member 2 is inserted into the annular hole 1110 of the balancing ring 1 to spray water toward the water inlet 102, so that water can enter the chamber 101 of the balancing ring 1, and the height of the water injection member 1 is not lower than the height of the central axis of the balancing ring 1, that is, the height of the lowest point of the water injection member 2 is higher than the height of the central axis of the balancing ring 1, so that the water injection member 2 can be located at a relatively high position, and when the laundry treating apparatus 1000 is washing, the water injection member 2 can reduce the entrance of lint dropped from the laundry during the washing and washing, so that the balancing system can balance the laundry more reliably and smoothly.

Here, it should be noted that, since the balance ring 1 rotates with the inner cylinder 20, in the technical solution in which the balance ring 1 is coaxial with the inner cylinder 20, the height of the central axis of the balance ring 1 does not change, whereas in the technical solution in which the balance ring 1 is eccentric with respect to the inner cylinder 20, the central axis of the balance ring 1 floats up and down within a small range with rotation, and the above-mentioned "the height of the water injection member 1 is not lower than the height of the central axis of the balance ring 1" means that the height of the water injection member 1 is not lower than the height of the central axis of the balance ring 1 when the balance ring 1 rotates to any angle.

No particular limitation is imposed on the specific height value of the water injection member 2 above the central axis of the balance ring 1, and optionally, according to some embodiments of the present invention, as shown in FIG. 38, the vertical distance between the water injection member 2 and the central axis of the balance ring 1 is d1, d1 is greater than or equal to 0.5r1, and r1 is the inner diameter of the balance ring 1, i.e., the radius of the inner circumferential surface of the balance ring 1. Thus, the distance between the water injection piece 2 and the washing liquid level is larger, the water injection piece 2 is effectively prevented from being submerged by washing water, the washing water is further reduced from entering the water injection piece 2, and the washing water splashed upwards can be particularly prevented from entering the water injection piece 2.

As an alternative embodiment, the vertical plane of the rotation axis of the inner cylinder 20 may pass through the water injection member 2, for example, in the embodiment shown in fig. 3, the vertical plane of the rotation axis of the inner cylinder 20 (i.e., the central axis of the inner cylinder 20) may pass through one end of the water injection member 2, and for example, in the embodiment shown in fig. 6, the vertical plane of the rotation axis of the inner cylinder 20 may pass through substantially the middle of the water injection member 2. Thus, the water injection member 2 tends to be disposed at a higher position, and further, foreign substances such as washing water and lint are avoided.

Optionally, according to some embodiments of the present invention, the water injection member 2 may be disposed within a range corresponding to a central angle α 2, a center of the central angle α 2 is located on the rotation axis of the inner cylinder 20, and the central angle α 2 may be bisected by a vertical plane in which the rotation axis of the inner cylinder 20 is located, where α 2 is equal to or less than 120 degrees. That is, the water injection member 2 may be provided at any position within an angular range of 120 degrees of the upper portion of the inner tube 20 with reference to the inner tube 20. Therefore, the distance between the water injection piece 2 and the washing liquid level is large, and water inflow and flock of the water injection piece 2 are effectively avoided. Further, α 2 further satisfies: alpha 2 is less than or equal to 60 degrees. Thus, the water injection member 2 is disposed at a higher position, and the effect of preventing foreign matter from entering is more excellent.

the water board 40 is further described below with reference to some of the drawings and embodiments.

Referring to fig. 41 to 49, in some embodiments of the present invention, the water receiving plate 40 is an arc-shaped plate extending along the circumferential direction of the balance ring 1, a part of the arc-shaped plate is disposed at the lower half portion of the inner side of the balance ring 1, and another part of the arc-shaped plate may be located outside the ring hole 1110 and may be higher or lower than the lower hole wall of the ring hole 1110 (as shown in fig. 45, the mounting flange 42 at the axially outer end of the water receiving plate 40 extends downward to be lower than the lower hole wall of the ring hole 1110).

Of course, the above is only a part of the embodiments of the present invention, and in other embodiments of the present invention, the water receiving plate 40 may fully extend into the ring hole 1110 of the balance ring 1, and have a height higher than the lower hole wall of the ring hole 1110 and lower than the central axis of the balance ring 1. For example, in some embodiments of the invention, the upper portion of the water receiving plate 40 may also extend upward beyond the height of the central axis of the gimbal 1. That is, in the embodiment of the present invention, at least a portion of the water receiving plate 40 may be disposed at a lower half portion of the inner side of the gimbal 1.

as shown in fig. 43, according to some embodiments of the present invention, the central angle of the water receiving plate 40 is α 3, where α 3 satisfies: alpha 3 is more than or equal to 60 degrees and less than or equal to 200 degrees, good water retaining effect can be achieved within the angle range, and water falling from the upper part of the balance ring 1 is reduced and drops into the balance ring 1 again. It can be understood that, in order to realize a good water retaining effect, the water receiving plate 40 is preferentially arranged at the middle position of the lower half part of the inner side of the balance ring 1, and the heights of the two ends of the water receiving plate 40 can be set to be the same or different. To achieve better water receiving effect, α 3 may be further set within a range of 120 to 180 degrees. Optionally, in some specific examples of the present invention, α 3 is respectively 90 degrees, 120 degrees, 160 degrees, 180 degrees, and the like.

In some embodiments of the present invention, the heights of both circumferential ends of the water receiving plate 40 (i.e., both circumferential ends of the water receiving plate 40 along the balance ring 1) are not higher than the height of the central axis of the balance ring 1, and α 3 is greater than or equal to 120 degrees and less than or equal to 180 degrees, at this time, the effective utilization rate of the water receiving plate 40 is greater, and the water receiving effect is good. As shown in fig. 43, the lowest portion of the water receiving plate 40 may be provided with a drain port 401, so as to ensure that the water receiving plate 40 drains more thoroughly and smoothly, and reduce the amount of stagnant water on the water draining plate 40.

As shown in fig. 41 to 48, the axial outer end of the water receiving plate 40 is connected to the side wall of the outer cylinder 30, and a drain 401 is provided at the connection point, at least a part of the upper surface of the water receiving plate 40 is formed as a water receiving surface for receiving water, and the water receiving surface extends downward relative to the horizontal direction and obliquely toward the direction close to the drain, as shown in fig. 45, the inclination angle of the water receiving surface relative to the horizontal direction is β, where β satisfies: beta is more than or equal to 3 degrees and less than or equal to 20 degrees. Like this, the water receiving face of small-angle slope not only can realize good water receiving effect, and the water receiving face can have the effect of water guide moreover, makes water flow down in time from water collector 40, avoids water to deposit for a long time on water collector 40. For example, in some specific examples of the invention, β is 5 degrees, 10 degrees, 12 degrees, 15 degrees, 17 degrees, etc., respectively.

Optionally, as shown in fig. 45, an upward protruding water retaining flange 41 is disposed at an axial inner end of the water receiving plate, the water retaining flange 41 may have a water retaining effect, so that water is prevented from flowing back from the axial inner end of the water receiving plate 40, and the water flow direction is more controllable.

According to some embodiments of the present invention, as shown in fig. 42 to 45, the axially outer end of the water receiving plate 40 is provided with a mounting flange 42 protruding downward, and the water receiving plate 40 is connected to the outer cylinder 30 through the mounting flange 42, so that the installation is more convenient and firm. The underside of the water receiving plate 40 may be provided with a reinforcing structure 43, the reinforcing structure 43 being connected to the mounting flange 42. From this, additional strengthening 43 can not take place to interfere with water receiving water guide structure, and the water receiving face can set up to the smooth surface to do benefit to the water guide, can improve water receiving plate 40's bulk strength moreover, water receiving plate 40 installs more reliably, and shape stability is high, is difficult for taking place to warp. With this structure, when there is a gap between the mounting flange 42 and the outer cylinder 30, water on the water receiving plate 40 can flow out not only from the drain port 401 but also downward between the inner and outer cylinders from the gap.

The specific structure of the reinforcing structure 43 is not particularly limited, and optionally, in some embodiments of the present invention, as shown in fig. 47 to 49, the reinforcing structure includes a plurality of reinforcing ribs, the plurality of reinforcing ribs are distributed at intervals along the circumferential direction of the water-receiving plate, and each reinforcing rib extends from the axial inner end of the water-receiving plate 40 to the inner side surface of the mounting flange 42 to be connected with the mounting flange 42, so that the reinforcing structure 43 is not only convenient to manufacture, but also has a good reinforcing effect.

Referring to fig. 41 to 46, in some embodiments of the present invention, a balancing ring 1 is installed at the front portion of the inner cylinder 20, and a front cover portion 50 extending into a ring hole 1110 of the balancing ring 1 is provided at the front portion of the inner cylinder 20, and the front cover portion 50 can receive water falling from the upper portion of the balancing ring 1. The water receiving plate 40 is provided between the front cover part 50 and the balance ring 1 to receive water falling from the front cover part 50. Thus, water falling from the upper portion of the balance ring 1 may flow to the drain plate 40 through the transition of the front cover portion 50, and water falling on the front cover portion 50 may flow from the upper portion thereof to the lower portion thereof and then fall on the drain plate 40. Therefore, the water receiving fall between the upper part of the balance ring 1 and the water receiving plate 40 can be reduced, and the water receiving effect is better.

As shown in fig. 46 and 47, the front cover part 50 is provided at the axial front end thereof with a water blocking edge 51 protruding outward, so that a water guiding groove 52 can be formed on the outer circumferential surface of the front cover part 50, water falling onto the front cover part 50 can flow to the water guiding groove 52 and then flow downward along the water guiding groove 52, the water flow control effect is better, and the water blocking edge 51 can block the water from overflowing outward, resulting in being poured into the inner barrel 20.

Alternatively, the protruding height H of the water blocking edge 51 may satisfy: h is larger than or equal to 3mm, and the water receiving plate 40 can extend forwards to exceed the water retaining edge 51. Therefore, the water baffle 51 has a moderate height, so that a good water baffle effect can be ensured, meanwhile, a sufficient gap can be ensured between the water baffle and the balance ring 1, and the water receiving plate 40 can more completely receive water falling from the front cover part 50.

The water guard plate 51 may be a straight edge or a bent edge. For example, as shown in fig. 45 and 46, in some embodiments of the present invention, the water guard edge 51 may be formed to be bent outwardly and then rearwardly. This makes the front cover 50 smoother, improves the strength and appearance of the front cover 50, and improves the water blocking effect.

As shown with continued reference to fig. 45 and 46, according to some embodiments of the present invention, at least a portion of the outer circumferential surface of the front cover portion 50 may extend obliquely forward and inward with respect to the axial direction of the inner tube 20, whereby the front cover portion 50 may form a flow guiding structure, so that the water flow on the front cover portion 50 is more controllable.

alternatively, the entire front cover portion 50 may be inclined substantially along one angle, or may be inclined and extend at a plurality of angles, for example, in the embodiment shown in fig. 45 and 46, the outer peripheral surface of the front cover portion 50 includes a first guide surface 53 and a second guide surface 54, the second guide surface 54 extends obliquely forward and inward with respect to the axial direction of the inner cylinder 20, the second guide surface 54 is located at the rear side of the first guide surface 53, the second guide surface 54 extends obliquely forward and inward with respect to the axial direction of the inner cylinder 20, and the inclination angle of the second guide surface 54 is larger than the inclination angle of the first guide surface 53. Therefore, the front cover 50 is formed with two inclined surfaces, which not only facilitates the diversion of water, but also makes it easier for water to concentrate in the water chute 52 and flow downward. Alternatively, the first flow guiding surface 53 and the second flow guiding surface 54 may be connected in a step shape, which not only has a good flow guiding effect, but also has a high structural strength.

Fig. 50 to 58 illustrate a laundry treating apparatus 1000 according to one embodiment of the present invention, the laundry treating apparatus 1000 including an inner tub 20, an outer tub 30, a balance ring 1, a water filling member 2, and the like. The outer cylinder 30 has an outer cylinder chamber 310, the inner cylinder 20 is rotatably disposed in the outer cylinder chamber 310, and the inner cylinder 20 has a rotation axis disposed horizontally, but of course, in other embodiments of the present invention, the inner cylinder 20 may have an inclined rotation axis. The balance ring 1 is connected with the inner cylinder 20 to rotate along with the inner cylinder 20, and the central axis of the balance ring 1 is coincided with the rotating shaft of the inner cylinder 20. Of course, in other embodiments of the invention, the central axis of the balancing ring 1 may also be parallel to the axis of rotation of the inner cylinder.

the balance ring 1 has a chamber 101 therein, and the inner circumferential surface of the balance ring 1 has a water inlet 102 for feeding water. The laundry treating apparatus 1000 may achieve balancing by injecting water into the chamber 101 of the balancing ring 1. The structure of the balance ring 1 is substantially similar to that of the balance ring 1 in some embodiments described above, and reference is made to the above description, which is not described in detail herein.

In this embodiment, the laundry processing apparatus 1000 may further introduce hot air into the inner drum 20 to dry the laundry in the inner drum 20, and the laundry processing apparatus 1000 further has a condensation chamber, in which the wet air after heat exchange with the wet and cold laundry may be condensed. Wherein, the water injection piece 2 can inject water into the condensation cavity so as to enable the condensation cavity to have condensed water. In this embodiment, the water injection member 2 may also inject water into the balance ring 1, and water injected from the water injection port 201 of the water injection member 2 may enter the chamber 101 through the water inlet 102.

in some correlation techniques, the water injection structure to the condensation chamber water injection and the water injection structure to the balance ring water injection are different structures, and the clothes treatment equipment needs to have two sets of water injection structures, so that the cost is increased, the installation is inconvenient, the occupied space is also reduced, the structure is not compact, the size of the clothes treatment equipment is increased under the same washing capacity, or the washing capacity is reduced under the same whole machine size, and the great waste is caused.

in the embodiment of the present invention, the laundry treating apparatus 100 may inject water into the balance ring 1 through the water injection member 2, or may inject water into the condensation chamber through the water injection member 2, so that the water injection system may be shared by the water injection of the balance ring 1 and the water injection of the condensation chamber, thereby reducing the number of components, saving the internal space, facilitating the improvement of the space utilization rate and the increase of the washing volume, and reducing the cost of the laundry treating apparatus 1000.

According to some embodiments of the present invention, the water injection member 2 may inject water to the balance ring 1 and the condensation chamber at different stages, for example, in the laundry treating apparatus 1000 having a drying mode and a washing mode, the water injection member 2 may inject water to the condensation chamber in the drying mode and inject water to the water inlet 102 to achieve water injection to the balance ring 1 in the washing mode. In the washing mode, the water injection part 2 can control water injection to the water injection part 2 according to the stage of balancing required, and if the washing mode comprises a rinsing stage, a dewatering and spin-drying stage and other stages, the water injection part 2 can inject water to the balancing ring 1 in the dewatering and spin-drying stage to realize balancing.

the specific arrangement position of the condensation cavity is not particularly limited, and the condensation cavity can be flexibly arranged at a position which is beneficial to water injection of the water injection member 2, and the position is easy to understand for a person skilled in the art. For example, in some embodiments, the condensation chamber is disposed adjacent to the water injection member 2 and has a port facing the water injection member 2 such that the water injection member 2 can inject water into the condensation chamber through the port. In some specific examples, the water injection member 2 is movably arranged, so that water can be injected to the corresponding part conveniently and pertinently, and the water injection effect is improved.

alternatively, in some embodiments of the present invention, for example, as shown in fig. 50 to 52, the outer drum cavity 310 may be used as a condensation cavity, specifically, the outer drum cavity 310 may be used as a cavity for storing water in cooperation with the inner drum 20 when the laundry treating apparatus 1000 is in the washing mode; when the laundry treating apparatus 1000 is in the drying mode, the outer drum cavity 310 can be used as a condensing cavity, and the air blown out from the inner drum 20 can enter the outer drum cavity 310 to condense in the outer drum cavity 310. Therefore, the condensation cavity does not need to be additionally arranged, the outer cylinder cavity 310 can realize the effect of one object with multiple purposes, the utilization rate of the internal space is higher, and the miniaturization of the clothes treatment equipment and the larger treatment volume are facilitated.

In such an embodiment, the water injection member 2 may inject water into the outer cylindrical cavity 310 directly when injecting water into the condensation cavity, or may inject water into the balance ring 1 first and then flow out from the balance ring 1 to the outer cylindrical cavity 310. Specifically, clothes treating apparatus 1000 is under the stoving mode, the rotational speed of inner tube 20 and stabilizer ring 1 is lower, and centrifugal force is less, and this moment, if there is water in the stabilizer ring 1, when water rotates the upper portion of stabilizer ring 1 along with stabilizer ring 1, centrifugal force is less than the action of gravity, and water can flow out in stabilizer ring 1 naturally to flow into outer cylinder chamber 310 in, at this moment, stabilizer ring 1 can play the effect of supplementary notes water 2 water injection, makes the water can pour into outer cylinder chamber 310 into more evenly, and the water injection effect promotes.

In practical use, the balance ring 1 is generally used in the laundry processing apparatus 1000 during spin-drying, at this time, the rotation speeds of the inner drum 20 and the balance ring 1 are high, and the centrifugal force is large, at this time, when there is water in the balance ring 1, even if the water rotates to the upper portion of the balance ring 1 along with the balance ring 1, since the centrifugal force is greater than the gravity, the water does not flow out from the balance ring 1, at this time, the balance ring 1 can continuously maintain the balance adjusting function until the rotation speed of the inner drum 20 is reduced.

like this, no matter annotate water spare 2 to the water injection of balance ring 1, still to outer barrel cavity 310 water injection, all can realize to balance ring 1 water injection through annotating water spare 2, water injection control structure is simpler controllable, and the water injection effect is better simultaneously.

Although the water injection member 2 for injecting water indirectly into the outer cylindrical chamber 310 by directly injecting water into the gimbal ring 1 is also a water injection member for injecting water into the gimbal ring 1 in the above description, the water injection member 2 may be provided to inject water only into the outer cylindrical chamber 310, that is, the water injection member 2 may maintain the state in which water is injected into the gimbal ring 1 to achieve water injection into the outer cylindrical chamber 310, but a water injection structure for injecting water into the gimbal ring 1 to achieve balance adjustment may be a water injection structure provided separately from the water injection member 2. That is, the balance ring 1 and the outer cylinder cavity 310 may not share a set of water injection system, and in the drying mode, indirect water injection may be achieved to the outer cylinder cavity 310 through the water injection member 2, specifically, the water injection member 2 may inject water to the chamber 101 through the water inlet 102, and when the water injected into the chamber 101 rotates to the upper portion along with the balance ring 1, the water flows out from the water inlet 102 and flows into the outer cylinder cavity 310 under the action of gravity; in a washing mode (e.g., in a spin drying), the balancing ring 1 may be supplied with water through another water supply structure.

in the embodiment that the balance ring 1 and the outer cylinder cavity 310 do not share the water injection structure and the water injection member 2 injects water to the outer cylinder cavity 310 indirectly, compared with the mode of direct water injection in the related art, the water injection effect of the clothes treatment equipment 1000 to the outer cylinder cavity 310 is improved to some extent, water can drip downwards from the balance ring 1, not only can the water injection height be improved by means of the balance ring 1, but also the water flowing out from the balance ring 1 can be in the downward dripping effect, so that the water injection is more uniform, the water injection area is larger, the cooling area of water flow can be increased to a greater extent, the condensation effect is larger, the material cost of a condensation system is greatly reduced, and the requirement of the condensation system on the structural space of the clothes treatment equipment 1000 is also reduced.

Alternatively, the balancing ring 1 can be disposed at the front part of the inner barrel 20, at the rear part of the inner barrel 20, or the balancing ring 1 can be disposed at both the front part and the rear part of the inner barrel 20 to achieve simultaneous front-rear balancing. Referring to fig. 50 to 56, in some embodiments of the present invention, the tub chamber 310 is a condensing chamber in the drying mode, the balancing ring 1 is provided at the rear of the tub 20, and at least a portion of the water flowing out of the water inlet 102 can flow down along the rear sidewall of the tub 30. Therefore, the contact area of the water and the outer cylinder 30 is larger, the condensation effect on the air can be improved, meanwhile, the water injection is closer to the rear part of the outer cylinder 30 and is further away from the inner cylinder 20, and the phenomenon that the water enters the inner cylinder 20 to re-wet the dried clothes can be reduced.

in some embodiments of the present invention, the water flowing out from the balancing ring 1 flows downwards along the rear sidewall of the outer cylinder 30, and in other embodiments of the present invention, a part of the water flowing out from the balancing ring 1 flows downwards along the rear sidewall of the outer cylinder 30, and another part of the water does not flow against the rear sidewall of the outer cylinder 30, but directly falls at a position adjacent to the rear sidewall of the outer cylinder 30, and the falling water can flow to the bottom of the outer cylinder cavity 310, so that the outer cylinder 30 can be cooled, and the condensation effect can also be achieved.

In order to improve the water injection effect, optionally, the water injection member 2 may inject water to the balance ring 1 along a predetermined water injection direction, which may be referred to in fig. 33, specifically, the water injection member 2 has the water injection port 201 located in the annular hole 1110 of the balance ring 1, and an angle α formed by a water outlet direction of the water injection port 201 and a direction of a linear velocity of the balance ring 1 at a drop point Z of a water outlet flow of the water injection port 201 is smaller than 90 °, so that splashing of water may be reduced, and water injection may be smoother.

further, referring to fig. 55, a falling point Z of the water injection flow of the water injection member 2 is located at an upper portion of the gimbal ring 1 and at a downstream side of a water outlet portion of the gimbal ring 1 (i.e., a portion of the gimbal ring 1 from which water flows out, in some embodiments, a portion of the balancing ring 1 from which water flows out is located at a highest point of an inner circumferential surface of the gimbal ring 1, and in other embodiments, a portion of the balancing ring 1 from which water flows out is located at a position slightly lower than a highest point of the inner circumferential surface of the gimbal ring 1, or a position within a range extending from the highest point of the inner circumferential surface of the gimbal ring 1 to both sides by a predetermined distance) in a rotation direction W of the gimbal ring 1, and an inclination angle θ: theta is more than or equal to 15 degrees and less than or equal to 75 degrees. For example, θ can be 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, and the like.

like this, not only can guarantee good water injection effect, even the stabilizer ring 1 is in the state of going out water when the water injection moreover, the water that flows out from the play water position of stabilizer ring 1 can keep away from water injection spare 2, reduces unrestrained to water injection spare 2, and simultaneously, the water that gets into in the stabilizer ring 1 can move just to flow out in the stabilizer ring 1 after half a circle, can also play the effect of adjusting balance.

Therefore, the water receiving plate 40 can shield the balance ring 1, and water flowing out of the upper part of the balance ring 1 is prevented from falling into the balance ring 1. Here, the water receiving plate 40 may be similar to the water receiving plate 40 in some embodiments, and the structure thereof will not be described in detail herein, and reference may be made to the foregoing description.

Thus, the water guard 60 can block water from the upper side from falling into the lower portion of the balance ring 1, and the water guard 60 can also play a role of controlling water. The specific structure of the splash plate 60 will be described in further detail below.
