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

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

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

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

According to some embodiments of the present invention, as shown in fig. 1, a processing cartridge assembly 100 may include an outer cartridge 30, an inner cartridge 20, and a balance 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 central axis of the balancing device 1 is parallel to or coincident with the rotation axis of the inner cylinder 20, that is, the balancing device 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 balancing device 1 has a good balancing effect on the inner cylinder 20, when the balancing device 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 balancing device 1 and the rotating axis of the inner cylinder 20 may be set to be less than 5mm, for example, 2mm, 3mm, and the like.

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

The water injection piece 2 can inject water into the balancing device 1, so that the gravity center of the balancing device 1 is changed, the eccentricity of the inner barrel 20 is adjusted, and the effect of balancing 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 into the balancing device 1, so that the laundry treating apparatus 1000 has an active balancing control function.

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

Referring to fig. 3 to 8, in some embodiments of the present invention, the balancing apparatus 1 includes a body 11, in this embodiment, the body 11 is annular, and in other embodiments, the body 11 may not be annular, and for example, may be disc-shaped.

The three water passage grooves 103 may be arranged in a radial direction of the body 11. The three water channel grooves 103 are in one-to-one correspondence with the three chambers 101.

Therefore, the control of the water injection amount of the three chambers 101 can be realized by controlling the water injection amount of the three water channel grooves 103, when the required water amount needs to be injected into the corresponding chambers 101, the required water amount can be injected into the corresponding water channel grooves 103 through the water injection pieces 2, the water injection is more targeted, the balance response to load eccentricity is quicker, the regulation efficiency is higher, and the time for treating clothes can be effectively shortened. Wherein, the notch of the water channel groove 103 is the water inlet 102.

The chambers 101 and the water channel 103 may be in the same number and correspond to each other, or may be in different numbers and correspond to each other. That is, in an embodiment of the present invention, each chamber 101 may communicate with at least one water channel groove 103 to feed water into the chamber through the water channel groove.

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

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

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

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

This may further facilitate the water intake and drainage of the balancing apparatus 1.

Further, the groove bottom of the water passage groove 103 away from the notch overlaps with the radially inner end of the corresponding chamber 101 in the radial direction of the body 11. Like this, the water intaking in the water channel groove 103 can directly enter into the radial inner end of cavity 101, and the water that gets into can move under the effect of centrifugal force to the radial outer end of cavity 101 in order to vacate the convenient follow-up water of the radial inner end of cavity 101, can make like this intake more fast smooth and easy. When drainage is required, the rotational speed of the balancing device 1 is reduced and the water tends to move under gravity towards the radially inner end of the chamber 101, thus making it easier to enter the bottom of the channel groove 103 and thus also facilitating drainage.

As shown in fig. 6, the notch (i.e., the water inlet 102) may be inward beyond the radially inner end of the chamber 101 in the radial direction of the body 11. Like this, in balancing unit 1's upper portion, the notch can be less than the radial inner end of cavity 101, more does benefit to the discharge of water, and simultaneously, when intaking, water also does benefit to more under the centrifugal force and removes to the basin inslot, can reduce the loss volume of intaking.

According to some embodiments of the present invention, the water passage groove 103 may be outwardly not more than a half of a radial length of the corresponding chamber 101 in a radial direction of the body 11. In this way, the height of the water channel groove 103 is not too high at the upper part of the balancing device 1, so as to be more beneficial to the outward discharge of water, and the height of the water channel groove 103 is not too low at the lower part of the balancing device 1, so that the water in the chamber 101 can be reduced from being thrown out of the water channel groove 103 in the balancing process, the balancing effect is good, and the arrangement is also beneficial to the water inlet.

As shown in fig. 6, the water passage groove 103 extends obliquely outward with respect to the axial direction of the body 11 and inward with respect to the radial direction of the body 11. Here, inward is a direction toward the middle of the body 11, for example, toward the inside of the ring hole 1110 of the body 11. Thus, the obliquely arranged water channel 103 has a flow guiding effect on water, so that not only can water enter the cavity 101 more quickly under the action of centrifugal force when the water is injected into the body 11, but also the water can flow out more quickly under the action of gravity when the water is discharged outwards from the body 11, and the water inlet and discharge efficiency can be improved.

Alternatively, the radially inner side surface 1a of the water passage groove 103 may extend obliquely outward with respect to the axial direction of the body 11 and inward with respect to the radial direction of the body 11, as shown in fig. 6. Like this, when body 11 drainage, water can flow outwards along the radial medial surface 1a that the slope set up, and water can be more fast and outwards flow out more easily under the water conservancy diversion of radial medial surface 1a, and balancing unit 1's drainage performance promotes.

As shown in fig. 6, the radially inner side surface 1a of the water channel groove 103 may have an inclination angle γ 1 with respect to the axial direction of the body 11, and γ 1 may satisfy, according to some embodiments of the present invention: gamma 1 is more than 0 degree and less than or equal to 60 degrees, so that the water guide plate is convenient to manufacture and has excellent water guide effect. For example, in some specific examples of the present invention, γ 1 is 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, etc., respectively.

Alternatively, the radially outer side surface 1b of the water passage groove 103 may extend obliquely outward with respect to the axial direction of the body 11 and inward with respect to the radial direction of the body 11, as shown in fig. 6. Thus, when the body 11 is filled with water, the water can flow inwards along the inclined radial outer side surface 1b, the water can flow inwards into the cavity 101 more quickly and easily under the flow guidance of the radial outer side surface 1b, and the water inlet performance of the balance device 1 is improved.

With continued reference to fig. 6, the radially outer side surface 1b of the water channel groove 103 may have an inclination angle γ 2 with respect to the axial direction of the body 11, and γ 2 may satisfy, according to some embodiments of the present invention: gamma 2 is more than 0 degree and less than or equal to 60 degrees. Therefore, the water guide plate is convenient to manufacture and has excellent water guide effect. For example, in some specific examples of the invention, γ 2 is 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, etc., respectively.

It should be noted that, in the embodiment of the present invention, one water channel groove 103 may be obliquely disposed, a part of the water channels may be obliquely disposed, or all the water channel grooves 103 may be obliquely disposed, which may be specifically set according to actual situations; in a certain water channel groove 103, only the radially inner surface 1a of the water channel groove 103 may be obliquely arranged, only the radially outer surface 1b of the water channel groove 103 may be obliquely arranged, both the radially inner surface 1a and the radially outer surface 1b of the water channel groove 103 may be obliquely arranged, and the degree of inclination of the radially inner surface 1a and the radially outer surface 1b may be the same or different, and these may be selectively arranged according to actual conditions.

A balancing device 1 according to one embodiment of the invention is shown in fig. 1 to 8. The balancer 1 is annular as a whole and includes an annular body 11. The body 11 has three chambers 101 therein, and the three chambers 101 are spaced apart along the circumference of the body 11. The axial outer end of body 11 still is equipped with three water channel groove 103, and three water channel groove 103 communicates with three cavity 101 one-to-one, and every cavity 101 communicates with the water channel groove 103 that corresponds through the rectangular shape opening 104 of a plurality of circumference spaced apart settings along body 11, and a plurality of openings 104 are equidistant spaced apart to, every opening 104 all sets up on the axial wall of cavity 101. Each water channel groove 103 extends obliquely with respect to the axial direction of the body 11 outward and toward the direction inside the annular ring 1110, and the notch of the water channel groove 103 may be disposed opposite to the opening 104. The water passage groove 103 overlaps with the corresponding chamber 101 in the radial direction of the body 11. The axially outer end of the body 11 is provided with a groove into which the water channel 103 extends, which is advantageous for shortening the axial dimension of the body 11. Some internal corners within chamber 101 may be chamfered, for example, chamber 101 may include a first sub-chamber and a second sub-chamber, the first sub-chamber being radially outward of the second sub-chamber, the internal corners of the second sub-chamber proximate the notch may be chamfered, optionally the chamfer may be a fillet.

Alternatively, according to some embodiments of the present invention, as shown in fig. 3 to 6, the opening 104 for communicating the chamber 101 and the water channel groove 103 may be provided in the axial cavity wall of the chamber 101. Thus, the chamber 101 may have an axial water inlet structure, which is more adaptive to the structure of the axial water inlet channel 103, and the water inlet is smoother. In addition, the water channel groove 103 and the chamber 101 may overlap in the radial direction of the body 11, which is more beneficial to the water intake and drainage of the balancing device 1, and the balancing device 1 has a faster response speed in balancing, which is beneficial to better reduce the vibration of the clothes treatment apparatus 1000.

According to some embodiments of the invention, as shown in fig. 6, the axial cavity wall of the chamber 101 may have a wall portion perpendicular to the axial direction of the body 11, and the opening 104 may be provided in the wall portion. In this way manufacturing is facilitated and the water entering from the opening 104 can be guided by the wall portion to move faster towards the radially outer end of the chamber 101, which facilitates the draining, while at the same time the water in the chamber 101 can also flow faster to the opening 104 guided by the wall portion over a shorter distance, which results in an improved draining efficiency.

Alternatively, in some embodiments of the present invention, the opening 104 may extend along the axial direction of the body 11, which is more convenient for manufacturing and higher in forming accuracy, and the water at the opening 104 may flow along the axial direction of the body 11 with a shorter flow path. In other embodiments of the present invention, the opening 104 may extend obliquely outward relative to the axial direction of the body 11 and inward of the annular ring 1110 of the body 11. Thereby, the water is displaced obliquely outwards in relation to the axial direction at the opening 104, so that the water can also enter the chamber 101 relatively quickly by the action of the centrifugal force and the guiding action of the inclined opening 104, and the angle of the water when entering the chamber 101 with the radial direction of the chamber 101 is typically less than 90 degrees, which reduces the resistance to the turning of the water, so that the water is more likely to flow under the action of the centrifugal force towards the radially outer end of the chamber 101, and which is also advantageous for drainage.

As shown in fig. 6, according to some embodiments of the present invention, the inner end of the opening 104 is flush with the inner end of the chamber 101 in the radial direction of the body 11. Thus, no step or section difference exists between the inner end of the opening 104 and the radial inner end of the body 11, the resistance of water inlet and outlet is reduced, water inlet and water discharge are smoother and more thorough, and the water accumulation in the chamber 101 during water discharge and the water accumulation at the outlet during water inlet are reduced.

Alternatively, both ends of the opening 104 are flush with both ends of the groove bottom of the water passage groove 103, which is away from the notch, respectively, in the radial direction of the body 11, as shown in fig. 6. Like this, in the footpath of body 11, the size of opening 104 equals with the tank bottom size of water channel groove 103 for the velocity of flow is unchangeable basically when the business turn over opening 104 for water, and rivers are more stable, simultaneously, can further reduce uneven structures such as the segment difference or the step of opening 104 department, further reduce the water resistance, promote the smooth and easy nature that rivers flow.

The number of the openings 104 is not particularly limited, and the openings can be flexibly arranged according to actual conditions, and one or more openings 104 can be provided to communicate with each chamber 101. When the number of the openings 104 is plural, the plural openings 104 may be spaced apart along the circumference of the body 11, as shown in fig. 7, so as to improve the uniformity of water intake and drainage, increase the probability of water intake and drainage, and improve the efficiency of water intake and drainage. The opening 104 may be an elongated opening extending along the circumference of the body 11, which not only facilitates manufacturing, but also facilitates water ingress and drainage.

In some embodiments of the invention, as shown in fig. 7, the elongated opening may be a curved waist-shaped opening, and the two centers of the waist-shaped opening are concentric with the body 11. Therefore, the shape of the opening 104 is more adaptive to that of the body 11, the influence of the opening 104 on the overall balance performance of the balance device 1 can be reduced, the structural design of the balance device 1 is more reasonable, and the comprehensive performance is improved.

With reference to some embodiments of the present invention, each chamber 101 may communicate with the corresponding water channel 103 through a plurality of spaced openings 104, so that water inlet and outlet effects are better. Further, as shown in fig. 7, in the circumferential direction of the body 11, both ends of the distribution area of the openings 104 may be respectively shorter than both ends of the chamber 101, that is, both ends of the chamber 101 respectively exceed both ends of the distribution area of the openings 104 in the circumferential direction of the body 11, where edges of both ends of the distribution area of the openings 104 are respectively based on the edge lines of the openings 104 at both ends, in other words, the openings 104 at both ends do not exceed both ends of the chamber 101 in the circumferential direction of the body 11. In this way, manufacturing is facilitated and the influence of the opening 104 on the balancing device 1 can be reduced.

Alternatively, as shown with reference to fig. 7, the distance separating two adjacent openings 104 may be less than one fifth of the extension length of the openings 104. Therefore, the interval between the openings 104 is relatively smaller, the size of the openings 104 is relatively larger, the water passing area can be increased, water inlet and water discharge tend to be continuous in the circumferential direction of the body 11, continuous water inlet flow and water outlet flow are achieved, and the water inlet effect and the water outlet effect can be improved.

In some specific examples of the present invention, as shown in fig. 7, the chambers 101 are in the same number and in one-to-one correspondence with the water channel grooves 103, and a plurality of chambers 101 may be in communication with the corresponding water channel grooves 103 through the same number of openings 104. Thus, the balance device 1 is more convenient to manufacture, more uniform in gravity distribution and better in self-balance.

Referring to fig. 9-14, according to some embodiments of the invention, at least one internal corner 1120 of at least one chamber 101 may be chamfered. In the description of the present invention, the "internal angle" is also called the reentrant angle, i.e. the angle of concavity, which is less than 180 degrees. The "external angle" is also referred to as a convex angle, i.e., a raised angle, which is greater than 180 degrees.

Research shows that the internal corner 1120 has a certain adhesion effect on water, when the balancing apparatus 1 is draining, the outflow speed of water at the internal corner 1120 is slower than that of water at other positions in the chamber 101, and the water at the internal corner 1120 is difficult to drain and easy to accumulate at the internal corner 1120, which not only affects the drainage performance of the balancing apparatus 1, but also is easy to breed bacteria for a long time, thereby reducing the cleanliness of the interior of the clothes treatment apparatus. And when setting up reentrant corner 1120 chamfer, not only can improve the dead angle structure of reentrant corner 1120 department, reduce the deposit of water, the chamfer can also play certain water conservancy diversion effect to water moreover, not only makes the outflow speed of water promote, and water exhaust is also cleaner moreover, can promote balancing unit 1's drainage effect and efficiency. Moreover, when injecting water into the body 11, some chamfers can also play the effect of water guide for water flows in cavity 101 more easily, thereby can also promote into water efficiency.

Alternatively, in actual manufacturing, the internal corners 1120 to be chamfered may be flexibly set in consideration of the water intake and drainage conditions, the manufacturing conditions, and the like, for example, all the internal corners 1120 may be chamfered, or some of the internal corners 1120 may be selected. Optionally, according to some embodiments of the invention, the channel slots 103 and the corresponding chambers 101 communicate through the openings 104, at least one internal corner 1120 of each chamber 101 near the opening 104 being chamfered. In this way, the chamfer may be adjacent to the opening 104, which may further enhance the water diversion effect.

Referring to fig. 11-14, chamber 101 may include a first sub-chamber 101a and a second sub-chamber 101b, with second sub-chamber 101b being located radially outward of first sub-chamber 101a, that is, first sub-chamber 101a being closer to an inner circumferential surface of body 11 and second sub-chamber 101b being closer to an outer circumferential surface of body 11. The opening 104 may be provided in the wall of the first sub-chamber 101a, so that water can be fed from the inner side of the chamber 101, and the water feeding effect is good. The volume of the second sub-cavity 101b can be greater than the volume of the first sub-cavity 101a, so that water can be stored in the cavity 101 more favorably, and the effect of balance adjustment can be favorably improved.

Optionally, at least one internal corner 1120 of the first sub-cavity 101a may be chamfered and at least one internal corner 1120 of the second sub-cavity 101b may be chamfered. Like this, not only can improve the water guide effect of first sub-chamber 101a, can improve the water guide effect of second sub-chamber 101b moreover, can show and improve into drainage effect.

It should be noted that only one chamber 101 may be configured to include the first sub-chamber 101a and the second sub-chamber 101b, or a plurality of chambers 101 may be configured to have the above structure, and the number of chambers 101 configured to have the above structure may be flexibly configured according to actual situations.

According to some embodiments of the present invention, referring to fig. 14, the opening 104 may be provided on an axially outer wall surface of the first sub-cavity 101a and provided with the opening 104, the opening 104 communicates the water channel groove 103 and the first sub-cavity 101a so that the water channel groove 103 and the chamber 101 can communicate, an axially outer end of the second sub-cavity 101b may extend outward beyond the first sub-cavity 101a, and a junction of a radially inner wall surface of the second sub-cavity 101b and the axially outer wall surface of the first sub-cavity 101a forms an external corner, and an internal corner 1120 between the radially inner wall surface of the second sub-cavity 101b and the axially outer wall surface of the second sub-cavity 101b may be chamfered, and for convenience of description, the chamfered internal corner 1120 is referred to as a first chamfer 1121.

From this, first chamfer 1121 can be with the water that is located the axial outer end department of second subchamber 101b towards opening 104 water conservancy diversion for water is changeed when balancing unit 1 low-speed is rotated and is flowed to opening 104 through the external corner more easily, promotes drainage ability, and the external corner then can block water and outwards flow, makes water can deposit more steadily in second subchamber 101b when high-speed is rotated, improves the stability of adjusting the balance.

Further, a portion of the radial inner wall surface of the second subcavity 101b between the corner tip of the male corner and the first chamfer 1121 may extend in the axial direction of the body 11, and an extension length of the portion in the axial direction of the body 11 may be smaller than a dimension of the first chamfer 1121 extending in the axial direction of the body 11. In this way, not only is manufacturing easier, but the chamfer is relatively larger in size, which may improve the water guiding effect so that water can flow more easily through the male corner and towards the opening 104.

As shown in fig. 14, according to some embodiments of the invention, the opening 104 may be disposed on an axially outer wall surface of the first sub-cavity 101a, and an internal corner 1120 between a radially inner wall surface of the first sub-cavity 101a and an axially inner wall surface of the first sub-cavity 101a may be chamfered, and for convenience of description, the chamfered internal corner 1120 is referred to as a second chamfer 1122. Therefore, the water in the first chamber 101 can flow to the opening 104 more quickly and easily under the flow guide of the second chamfer 1122, the water discharge effect can be further improved, the water entering from the opening 104 can be rushed to the second chamfer 1122 during water inflow, the water can naturally change the direction to flow into the second sub-chamber 101b under the flow guide of the second chamfer 1122, and the water inflow effect is further improved.

Further, a portion of the radial inner wall surface of the first subchamber 101a located between the second chamfer 1122 and the axial outer wall surface of the first subchamber 101a may extend in the axial direction of the body 11, and the extension length of the portion in the axial direction of the body 11 may be greater than the dimension of the second chamfer 1122 extending in the axial direction of the body 11. In this way, the size of the second chamfer 1122 is smaller, so that the occupation of the internal space of the first sub-cavity 101a adjacent to the opening 104 can be reduced under the condition of good water guiding effect, and the position of the first sub-cavity 101a corresponding to the opening 104 can have a larger space, so as to be more beneficial to the entry and the discharge of water.

Alternatively, the axial inner wall surface of the first sub-chamber 101a and the axial inner wall surface of the second sub-chamber 101b may join to form a plane perpendicular to the axial direction of the body 11. In this way, the inner wall surface of the chamber 101 in the axial direction may be substantially formed as a plane perpendicular to the axial direction of the body 11, the inner surface of the chamber 101 may be more flat, which not only facilitates manufacturing, but also the water may flow more smoothly in the chamber 101, the turbulent flow of the water may be reduced, and the water may flow more quickly and easily inward to the second chamfer 1122 or from the second chamfer 1122 into the second sub-cavity 101b under the flow guidance of the plane.

According to some embodiments of the invention, in the above description, the chamfer may be a rounded corner. Therefore, the water guide device is more convenient to manufacture, the water guide effect is further improved, and the water inlet and outlet performance of the balance device 1 is further improved. In some specific examples of the present invention, the rounded corners may correspond to a central angle of 90 degrees.

As shown in fig. 14, in some embodiments of the present invention, the outer external corner of the body 11 corresponding to the chamfer may be a rounded corner disposed concentrically with the chamfer. Thus, the balance device 1 is more beautiful in appearance, and the material consumption and the cost can be reduced.

Referring to fig. 9 to 14, the balancing apparatus 1 according to some embodiments of the present invention may include a body 11. Specifically, the body 11 may have a plurality of cavities 101 therein, and the plurality of cavities 101 may be distributed along the circumferential direction of the body 11. The axially outer side wall of the body 11 may be provided with a recess 1130 recessed into the cavity 101, and the recess 1130 may extend in the circumferential direction of the body 11. The inner wall surface of the recess 1130 may be provided with a plurality of openings 104.

A plurality of water channel grooves 103 are formed in the recessed portion 1130, the water channel grooves 103 may be arranged in a radial direction of the body 11, and each water channel groove 103 may extend in a circumferential direction of the body 11. Each chamber 101 may communicate with at least one water channel groove 103 through at least one opening 104, water may be introduced into the chamber 101 through the water channel groove 103, and the center of gravity of the laundry treating apparatus may be adjusted by controlling the amount of water introduced into each chamber 101, thereby achieving control of the balance of the laundry treating apparatus. A partition groove 1131 is formed between the groove side wall 1102 of the outermost water channel groove 103 and the side wall surface of the recessed portion 1130 in the radial direction of the body 11.

In the above structure, since the recess 1130 is disposed on the body 11, the water channel 103 can extend into the recess 1130, so that the axial dimension of the body 11 can be shortened under the condition that the depth of the water channel 103 is not changed, and the thickness of the balancing device 1 can be reduced, which is beneficial for installing other components in the laundry processing apparatus, such as the inner drum 20.

Simultaneously, the axial lateral wall of body 11 sets up to the partition recess 1131 that waits wall thickness and cooperation set up, more does benefit to and makes, and the product demolding nature is good, and the yield promotes, and the water channel groove 103 also is more convenient for set up simultaneously, can adjust water channel groove 103 according to the demand of advancing the drainage more easily to promote into drainage effect.

As shown in fig. 11 to 14, the outer end of the groove side wall 1102 of the water passage groove 103 may extend outward not beyond the axially outer end face of the body 11. In this way, the axial outer end of the balancing device 1 can be made more regular, and installation and manufacturing are facilitated. Further, the axially outer end face of the body 11 may be a plane perpendicular to the axial direction of the body 11, and the outer end of the groove side wall 1102 of the water passage groove 103 may be flush with the axially outer end face of the body 11. In this way, the structure of the balancing device 1 can be made more regular, making it easier to manufacture and install, and at the same time facilitating the installation of other components adjacent to the balancing device 1.

Of course, the present invention is not limited to such an arrangement, for example, in some embodiments of the invention not shown, the outer ends of the channel side walls 1102 of the water channel 103 may also extend outwardly beyond the axially outer end face of the body 11.

As shown in fig. 11 to 14, the recess 1130 may be provided at a radially inner end of the body 11 and communicate with the annular hole 1110 of the body 11. Accordingly, the radially inner wall surface of the recess 1130 may be completely absent or may be partially present.

Referring to fig. 11-14, in some embodiments of the invention, the junction of the sidewall surface of the recess 1130 and the axially outer end surface of the body 11 may be rounded, such as by a rounded corner. Thus, the sharp angle structure of the body 11 can be reduced, the beauty and safety of the balancing device 1 can be improved, and water inflow and drainage can be promoted. Alternatively, the radius of the fillet may be equal to or less than the dimension of the side wall surface of the recess 1130 extending in the axial direction of the body 11, the manufacturability is good, and the effect of promoting water inflow and drainage is good. The recess further describes the trough side wall 1102 of the water channel trough 103 below. As shown in fig. 11 to 14, in some embodiments of the present invention, the groove sidewall 1102 of the water channel groove 103 may be formed of a plurality of partition ribs, which may be spaced apart in a radial direction of the body 11, each partition rib may extend in a circumferential direction of the body 11, and the water channel groove 103 may be defined between adjacent two partition ribs. This configuration not only facilitates manufacturing, but also makes more efficient use of the space in the recess 1130.

According to some embodiments of the present invention, the body 11 is a unitary piece, in which case the channel side walls 1102 of the channel 103 are integrally formed with the body 11. Therefore, the balance device is convenient to manufacture, the structural connection firmness degree and the sealing performance are better, and water leakage of the balance device 1 can be avoided. In addition, the body 11 and the tank side wall 1102 of the water passage tank 103 may be provided with equal wall thickness, which may further improve the manufacturing performance.

Referring to fig. 15 to 26, in some alternative embodiments of the present invention, a plurality of partition ribs may be arranged in a radial direction of the body 11, and each partition rib may extend in a circumferential direction of the body 11. Each of the partition ribs may extend obliquely outward relative to the axial direction of the body 11 and toward the inside of the annular hole 1110 of the body 11.

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

As shown in fig. 15 and 16, the body 11 may include a plurality of tiles 1104, and the plurality of tiles 1104 are individually molded. That is, each tile 1104 is a separate molded tile. The plurality of splicing blocks 1104 are sequentially connected end to end along the circumferential direction of the body 11. Each separating rib is formed by sequentially connecting a plurality of rib segments 1103 arranged on a plurality of splicing blocks 1104 in a one-to-one correspondence manner. That is to say, each separation rib includes a plurality of muscle sections 1103 and these a plurality of muscle sections 1103 one-to-one set up on a plurality of splice 1103, still is provided with a plurality of muscle sections 1103 on every splice 1103 simultaneously and these a plurality of muscle sections 1103 belong to a plurality of separation ribs one-to-one respectively.

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

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

Referring to fig. 15 to 26, the plurality of tiles 1104 extend in the same length in the circumferential direction of the body 11. Therefore, the balance device is more convenient to manufacture, the splicing effect of the balance device 1 is better, and the whole structure is more stable.

Alternatively, as shown in fig. 16 to 21, two circumferential end surfaces of each of the tiles 1104 are respectively planes located in the axial section of the body 11. That is, the two circumferential end surfaces of each tile 1104 are each a plane, and the extension of the plane may pass through the central axis of the body 11. Thus, the splicing line of the two splicing blocks 1104 can be positioned in the radial direction of the body 11, the splicing gap is smaller, and the connection operation is more convenient.

According to some embodiments of the present invention, as shown with reference to fig. 15 to 26, the body 11 may include a first individual molding member 110 and a second individual molding member 120, the first individual molding member 110 and the second individual molding member 120 being respectively ring-shaped. The first individual molded article 110 includes the above-described plurality of tiles 1104, that is, the first individual molded article 110 is mainly composed of the plurality of tiles 1104. The first separate molding member 110 and the second separate molding member 120 may be axially connected, i.e., an axially inner end of the first separate molding member 110 and an axially outer end of the second molding member 120 may be connected together. Also, the first and second separate molding pieces 110 and 120 may cooperate to form a plurality of chambers 101. Therefore, the balance device 1 can be divided into more parts for molding, the mold size is smaller, the manufacturing efficiency is higher, and meanwhile, the splicing blocks 1104 can be axially positioned through the second single molding piece 120, so that the manufacturing error of the body 11 is smaller.

In some embodiments, the first individual molding member 110 and the second individual molding member 120 may be fusion-joined, that is, the first individual molding member 110 and the second individual molding member 120 may be axially fusion-joined. This not only facilitates the operation, but also ensures the connection between the first and second separate molding members 110 and 120 to be more reliable and have a better sealing property.

In some embodiments of the present invention, the second separately molded part 120 is formed by injection molding, and each of the splice 1104 and the corresponding rib segment 1103 are formed by injection molding, so that the manufactured balancing device 1 has high quality. The connection manner of the first single molding member 110 and each of the splicing blocks 1104 is not particularly limited, and optionally, in some embodiments of the present invention, the first single molding member and each of the splicing blocks 110 may be connected by heat melting, so that the connection quality is high.

As shown in fig. 16 and 17, the axially outer end surface of the second single molding member 120 may be provided with a plurality of second grooves 101b, the plurality of second grooves 101b may be provided at intervals in the circumferential direction of the second single molding member 120, the plurality of splice blocks 1104 may cover the plurality of grooves 101b in a one-to-one correspondence, the plurality of cavities 102 include a plurality of second grooves 101b in a one-to-one correspondence, and each of the second grooves 101b may constitute at least a part of the corresponding cavity 102. Therefore, the plurality of cavities 102 are more independent, the manufacturing is more convenient, the forming effect is better, and the product yield is improved.

As shown in fig. 17 to 20, the inner circumferential surface of the second separately molded part 120 may include a plurality of arc surfaces, the plurality of arc surfaces are distributed along the circumferential direction of the second separately molded part 120, the plurality of arc surfaces are in one-to-one correspondence with the plurality of second grooves 101b, and the inner surface of the radial inner wall surface of each second groove 101b is the corresponding arc surface. Each arc surface is a cylindrical arc surface or a conical arc surface, and each arc surface takes the central axis of the body 11 as a rotating shaft. The radiuses of the cambered surfaces are different so that a step is formed at the joint of two adjacent cambered surfaces. The structure is more matched with the structures of a plurality of chambers 101 with different volumes, so that the balance device 1 with axial water inflow is more convenient to manufacture, and the forming effect is better.

Alternatively, as shown in fig. 16 to 20, the junction between the radial inner wall surface and the axial inner wall surface of the second groove 101b may be rounded, for example, by a round corner transition, so that the inside of the chamber 101 may be more rounded, the water may flow more smoothly, and splashing of the water may be reduced. Optionally, the outer surface of the second single-molded part 120 corresponding to the connection portion is also in a round and smooth transition structure such as a rounded corner, which may further facilitate demolding, and at the same time, make the appearance of the balancing apparatus 1 more round and smooth, improve the appearance, and reduce interference with other components.

As shown in fig. 17, 21 to 26, in some embodiments of the present invention, the inner circumferential surface and the outer circumferential surface of the first separately molded member 110 may be concentrically disposed, and the inner circumferential surface and the outer circumferential surface of the first molded member 110 respectively have the central axis of the body 11 as a rotation axis, and the inner diameter of the axially inner end of the first separately molded member 110 is the same as the minimum inner diameter of the axially outer end of the second separately molded member 120. Here, the minimum inner diameter of the second separately formed piece 120 is the smallest one of the inner diameters of the plurality of arc surfaces of the second separately formed piece 120.

Thereby, the molding and the demolding are more convenient, and when the first individual molding member 110 and the second individual molding member 120 are connected together, the connection of the first individual molding member 110 and the second individual molding member 120 can be substantially flush, which not only facilitates the positioning connection but also makes the inner circumferential surface of the balancing device 1 smoother, which is more advantageous for reducing the interference with the installation of other components in the laundry treating apparatus 1000.

Alternatively, the axially outer end surface of the second separate molding member 120 may be a plane perpendicular to the axial direction of the body 11, and the axially inner end surface of the first separate molding member 110 may also be a plane perpendicular to the axial direction of the body, and these two planes may be fitted together, which facilitates the manufacture of the first separate molding member 110 and the second separate molding member 120, and the connection of the first separate molding member 110 and the second separate molding member 120 is more reliable and more airtight.

The axial inner end surface of each splicing block 1104 is provided with a first groove 101a, and each cavity 101 is formed by a second groove 101b and the first groove 101 a. This advantageously increases the volume of the chamber 101. Further, the radially inner end of the axially outer wall surface of each first groove 101a is provided with an opening 104, the opening 104 may communicate the first groove 101a with the water passage groove 103, the opening 104 may include a plurality of openings 104, and the plurality of openings 104 may be spaced apart in the circumferential direction of the body 11. Therefore, the water channel groove 103 can feed water into the chamber 101 through the plurality of openings 104, the water feeding efficiency is higher, and the position of the openings 104 on the inner side is more favorable for utilizing the centrifugal force during water feeding and the gravity during water discharging, and is more favorable for water feeding and water discharging.

It should be noted that although in the embodiment shown in fig. 15 and fig. 26, the cavity 101 is formed by the first separate molding member 110 and the second separate molding member 120, and one part of the cavity 101 is disposed in the first separate molding member 110 and the other part is disposed in the second separate molding member 120, the balancing device 1 needs to be axially and circumferentially connected during manufacturing. However, the invention is not limited thereto, and in other embodiments of the invention, the second individual molding member 110 may be absent, and only the first individual molding member 120, and in this case, a cavity may be directly formed in each of the blocks 1104, and in this case, the balancing device 1 may be formed by only circumferentially splicing the plurality of blocks 1104.
