Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below are exemplary embodiments for explaining the present invention with reference to the drawings and should not be construed as limiting the present invention, and those skilled in the art can make various changes, modifications, substitutions and alterations to the embodiments without departing from the principle and spirit of the present invention, the scope of which is defined by the claims and their equivalents.

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 balance ring 1 includes an annular body 11, the body 11 has a chamber 101 therein, and the balance ring 1 has a water inlet 102 on an inner circumferential surface thereof. The water injection member 2 injects water into the balance ring, and the water outlet flow of the water injection port of the water injection member 2 enters the chamber 101 through the water inlet 102. Alternatively, the water inlet 102 extends along the circumferential direction of the body 11, i.e., 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 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. By the arrangement, the sufficient depth of the water channel groove 103 is ensured, and the splashing prevention function is also realized.

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 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, and the water injection port 201 is located in the ring 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 direction of 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 and fig. 32 to 36 show two 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.

Referring to fig. 32 to 35, 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.

The laundry treating apparatus 1000 according to the embodiment of the present invention may be a washing machine, a dryer, or a washer-dryer.

Taking a washing machine as an example, in some embodiments of the present invention, the control system may include a detection unit, wherein during the dewatering process of the washing machine, the rotation speed of the driving motor is changed from low to high, the detection unit may detect the vibration magnitude of the treatment tube device 100 in real time, and control the state of the water injection member 2 or a water supply pipe connected to the water injection member 2 according to the detected vibration signal and a control algorithm, so as to inject water into the corresponding cavity 101 of the balance ring 1, so as to balance the load eccentricity of the inner tube 20.

For example, when the eccentricity of the load is close to the first chamber 111, the water can be injected into the second chamber 121 and the third chamber 131, and the injected water can be accumulated on the outer wall surface of the balance ring 1 due to the centrifugal force, and the eccentricity of the load can be greatly balanced, so that the vibration of the treating drum device 100 of the washing machine can be effectively reduced during the dehydration.

When the dewatering is finished, the rotation speed of the driving motor is reduced, and the water in the chamber 101 flows out along the water inlet 102 under the action of gravity. The water flowing out of the balance ring 1 will flow onto the water receiving plate 40, and the water can flow out of the drain port 401 under the guidance of the water receiving plate 40 and flow to the bottom of the outer cylinder 30. At this time, the water in the outer tub 30 may be discharged through the drain pipe. Alternatively, the water supply and drainage of the washing machine may be provided at the front and rear sides of the washing machine, respectively, so that interference of water supply and drainage is less and the washing machine operates more reliably.
