A second aspect of the embodiments of the present application provides a cartridge assembly 100, please refer to fig. 2, fig. 3, and fig. 13 to fig. 15, which includes an inner cartridge 20, an outer cartridge 30, a water injection assembly 40, and a balancing apparatus 10 of any of the embodiments of the present application; the inner barrel 20 is rotatably arranged in the outer barrel 30, the annular water guide member 11 is connected with the inner barrel 20 and surrounds the top side of the inner barrel 20, and the plurality of water storage assemblies 12 are arranged along the circumferential direction of the inner barrel 20; the water filling assembly 40 is connected with the outer tub 30 to selectively fill water into the one or more annular water inlets 11b.

A third aspect of an embodiment of the present application provides a laundry device, referring to fig. 1, including a housing 200, a controller, and a cartridge assembly 100 of any embodiment of the present application; the cartridge assembly 100 is disposed in the housing 200, and the controller is electrically connected to the water injection assembly 40 to control the water injection assembly 40 to inject water to the annular water inlet 11b of the corresponding water inlet waterway 11 a.

It should be noted that, referring to fig. 13 to 15, the controller can control the water injection assembly 40 to inject water to only one of the annular water inlets 11b at a time, and also control the water injection assembly 40 to inject water to a plurality of annular water inlets 11b at the same time.

The laundry appliance may be any one or an integration of a dryer, an all-in-one washer dryer, a spin dryer, and a washer. The rotation axis of the inner tub 20 may be in a vertical direction, for example, the washing apparatus may be a pulsator washing machine, and the rotation axis of the inner tub 20 may also be inclined at a certain angle with respect to the vertical direction, for example, the washing apparatus may be a pulsator washing machine. The centre line of rotation of the balance 10 substantially coincides with the axis of rotation of the inner barrel 20, that is, the balance 10 may be arranged coaxially with the inner barrel 20.

In the washing stage, the rotation speed of the inner tub 20 is low, for example, 40 rpm, and the inner tub 20 is intermittently rotated, so that there is no need to balance the inner tub 20, and therefore, there is no need to fill the water storage chamber 121a with water in the washing stage, and the opening and closing unit 123 may close the water discharge port 12b to prevent wash water from flowing backward from the water discharge port 12b into the water storage assembly 12. Before the dehydration stage is started, the opening and closing unit 123 opens the water discharge port 12b so that water is not substantially stored in the water storage assembly 12 before the dehydration is started, and thus, it is possible to facilitate the water supply to the corresponding water tank 121 according to the load eccentricity information of the inner tub 20 at the dehydration stage.

Specifically, in the dehydration stage, the inner tub 20 initially rotates at a low speed, and if the inner tub 20 is eccentric by a load, the controller controls the water injection assembly 40 to actively supply water to the corresponding water tank 121, for example, if the load is eccentric to the right side of fig. 1, the water injection assembly 40 injects water to the left water tank 121 of fig. 1, so that the amount of injected water and the entire mass of the water storage assembly 12 together resist the load eccentricity of the inner tub 20. Even under the condition that the rotating speed of the inner cylinder 20 is low, as long as the inner cylinder 20 is eccentric in load, the water injection assembly 40 can inject water into the corresponding water tank 121 in time to resist the eccentric mass of the inner cylinder 20, and a good balance effect is achieved on the inner cylinder 20, so that the balance device 10 of the embodiment of the application can achieve a good balance effect on the inner cylinder 20 in the full rotating speed section of the inner cylinder 20.

It should be noted that, in some embodiments, the water storage assembly 12 may be disposed between the inner tub 20 and the outer tub 30 along a radial direction of the inner tub 20. In other embodiments, the water storage assembly 12 may also be disposed inside the inner tub 20 along the radial direction of the inner tub 20, so that the water storage assembly 12 does not occupy a narrow installation space between the inner tub 20 and the outer tub 30, and thus, the risk of collision of the inner tub 20 is not increased.

There are various positions of the annular water inlet 11b on the annular water guide 11, and in one embodiment, referring to fig. 3 to 7, the annular water inlets 11b of all the water inlet paths 11a are disposed on the top side of the annular water guide 11, thereby facilitating the water filling assembly 40 to fill the annular water inlets 11b with water. In other embodiments, the annular water inlets 11b of all the water inlet paths 11a may also be disposed on the radial sidewall of the annular water guiding member 11, specifically, in an embodiment where the water storage assembly 12 is disposed in the inner barrel 20, the annular water inlets 11b of all the water inlet paths 11a are disposed on the radial inner sidewall of the annular water guiding member 11, and in an embodiment where the water storage assembly 12 is disposed between the inner barrel 20 and the outer barrel 30, the annular water inlets 11b of all the water inlet paths 11a are disposed on the radial outer sidewall of the annular water guiding member 11, or, a part of the annular water inlets 11b of the water inlet paths 11a are disposed on the top side of the annular water guiding member 11, and another part of the annular water inlets 11b of the water inlet paths 11a are disposed on the radial sidewall of the annular water guiding member 11.

It should be noted that, in the embodiment where the water storage assembly 12 is disposed between the inner tub 20 and the outer tub 30, the annular water guide 11 surrounds the outer surface of the top end of the inner tub 20. In the embodiment where the water storage assembly 12 is provided to the inner tub 20, the annular water guide 11 surrounds the inner surface of the top end of the inner tub 20.

The water storage units 12 may be connected to each other or disposed at intervals, however, the water storage cavities 121a of each water storage unit 12 are not communicated with each other, that is, water in the water storage cavity 121a of one water storage unit 12 cannot flow into the water storage cavity 121a of another water storage unit 12. In one embodiment, the plurality of water tanks 121 are uniformly distributed along the circumferential direction of the annular water guide 11, that is, the plurality of water tanks 121 are uniformly distributed along the circumferential direction of the inner cylinder, thereby facilitating the balance adjustment of the load eccentricity occurring during the rotation of the inner cylinder 20.

In an embodiment, the water storage assemblies 12 may also be fixedly connected to the inner cylinder 20, for example, a stud may be provided on the water tank 121, a screw passes through the stud from one side of the water tank 121 radially far away from the inner cylinder 20 and is fastened to the inner cylinder 20, and the water tank 121 may also be welded to the inner cylinder 20, thereby preventing the water storage assemblies 12 from loosening.

The water storage cavity 121a of each water storage module 12 may be communicated with only one water inlet path 11a, or may be communicated with two or more water inlet paths 11a, however, each water inlet path 11a is communicated with only one water storage cavity 121a of one water storage module 12, that is, each water inlet path 11a can only supply water to the water tank 121 of one water storage module 12, and cannot simultaneously supply water to the water tanks 121 of a plurality of water storage modules 12.

The opening and closing unit 123 selectively opens or closes the drain opening in various ways, and in an exemplary embodiment, referring to fig. 7 to 9, the opening and closing unit 123 includes a float 1232, and the float 1232 can switch between an open state of opening the drain opening 121c and a closed state of closing the drain opening 121c under the combined action of its own weight and buoyancy. Specifically, the water outlet 121c may be disposed on a corresponding bottom wall of the water storage chamber 121a, and the float 1232 floats up by the washing water and blocks the water outlet 121c when the laundry device is in a washing state. It should be noted that when the float 1232 loses its buoyancy, the float 1232 can move downward under its own weight, and at this time, the float 1232 opens the water outlet 121c. When the laundry device is in the dehydrating state, the float 1232 drops down by its own weight and the drain port 121c is opened.

The float 1232 is not limited to be installed, for example, in an embodiment, referring to fig. 7 to 9, the opening and closing unit 123 includes an installation bracket 1231, the installation bracket 1231 and the water tank 121 are kept relatively static, that is, the installation bracket 1231 may be connected to the water tank 121, or may be connected to other components such as the inner cylinder 20, as long as it is ensured that the installation bracket 1231 does not move relative to the water tank 121, the float 1232 is located below the water outlet 121c and is slidably connected to the installation bracket 1231, and the float 1232 can slide toward the water outlet 121c under the action of buoyancy to close the water outlet 121c. That is, the float 1232 may open or close the drain opening 121c by sliding along the mounting bracket 1231, and thus, the control of the moving direction of the float 1232 may be facilitated.

In one embodiment, referring to fig. 3 to 5 and fig. 7 to 9, the water tank 121 includes a tank 1211 and a pipe 1212 connected to each other; the top end of the tube body 1212 is connected to the case 1211, the bottom end of the tube body 1212 is provided with a water outlet 121c, and the bottom end of the case 1211 is not lower than the bottom end of the inner tube 20. Specifically, in the embodiment where the water storage assembly 12 is disposed between the inner barrel 20 and the outer barrel 30, in this way, the water tank 121 is prevented from interfering with the outer barrel 30 during the rotation of the inner barrel 20. In the embodiment where the water storage assembly 12 is disposed in the inner tub 20, the water tank 121 does not substantially affect the bottom structure of the inner tub 20, and the water tank 121 can be installed on the existing structure of the inner tub 20.

In the embodiment where the water storage assembly 12 is disposed in the inner barrel 20, the bottom of the water tank 121 can be supported on the edge of the bottom of the inner barrel 20, so that the bottom of the inner barrel 20 can support the water tank 121 to improve the stress condition of the water tank 121.

In the embodiment where the water storage assembly 12 is disposed in the inner barrel 20, the bottom end of the tube 1212 is not higher than the bottom end of the inner barrel (20), and the bottom end of the tube 122 penetrates through the bottom of the inner barrel 20. That is, the bottom end of the pipe 122 is located at a lower position, so that the water in the outer tub 30 can be more reliably contacted.

In one embodiment, the mounting bracket 1231 is removably coupled to the tank 121, for example, in an embodiment of the tank 121 where the tube 1212 is disposed, the mounting bracket 1231 can be removably coupled to the tube 1212. Thus, the float 1232 can be easily attached or replaced, and in other embodiments, the attachment bracket 1231 can be detachably connected to a component such as a barrel body or a barrel bottom of the inner barrel 20, or the attachment bracket 1231 can be fixedly connected to a component such as a barrel body or a barrel bottom of the water tank 121 or the inner barrel 20, for example, the attachment bracket 1231 can be welded to a barrel body of the water tank 121 or the inner barrel 20, and the attachment bracket 1231 can be integrally formed with a barrel bottom of the inner barrel 20 by injection molding or the like.

When the float 1232 is in the closed state of closing the drain port 121c, the end surface of the end of the plug 12322 away from the sleeve 12321 abuts against the step surface 1212a, and the abutment surface abuts against the bottom end of the tank 121 located on the periphery of the drain port 121c. That is, the plug 12322 can simultaneously close both the inside and outside of the drain port 121c, thereby further improving the sealing effect.

In an embodiment, referring to fig. 7, 10 and 11, the water storage assembly 12 further includes at least one partition plate 122 disposed in the water storage cavity 121a, all the partition plates 122 divide the water storage cavity 121a into a plurality of sub-cavities 121d disposed in a vertical layered manner, and the sub-cavities 121d are communicated with each other through water passing ports. That is, the partition plates 122 are arranged substantially in the horizontal direction, and when the number of the partition plates 122 is plural, the plural partition plates 122 are disposed substantially in parallel at intervals.

For example, in one embodiment, a portion of the edge of each partition 122 is spaced from the inner wall of the casing 1211 to form a water outlet 122a, so that the sub-chambers 121d are sequentially communicated.

The plurality of sub-chambers 121d are vertically layered in the water storage cavity 121a, so that after the water enters the water storage cavity 121a, the water needs to sequentially flow through the sub-chambers 121d to finally reach the water outlet 121c, which is equivalent to prolonging the flow path and the flow time of the water flow in the water storage cavity 121a, and therefore, if the load eccentricity occurs when the rotation speed of the inner cylinder 20 is low, the water entering the water storage cavity 121a has a longer flow path and flow time, so that the water flow needs a relatively longer time to flow out from the water outlet 121c after entering the water storage cavity 121a, and it can be understood that, in the dehydration stage, the time when the inner cylinder 20 is in the low-speed stage is very short, the flow time of the water flow in the water storage cavity 121a is enough to enable the inner cylinder 20 to pass through the low-speed stage, and therefore, in the low-speed stage, the quality of the water injected into the water storage cavity 121a can basically serve as a quality balancing function, so that the balancing effect of the balancing device 10 is better. And after entering high-speed stage, the water in the water storage chamber 121a receives great centrifugal force, and hug closely the radial outside internal surface in water storage chamber 121a, rivers are difficult for flowing downwards under the action of gravity, make the rivers in the water storage chamber 121a stay in the water storage chamber 121a from this, and can not discharge from outlet 121c, the load is eccentric can obtain balance by a wide margin, vibration and noise that can effectual reduction laundry equipment when the dehydration, reduce the risk of hitting the bucket of inner tube 20, promote user experience and feel.

Moreover, the water storage cavity 121a is divided into a plurality of sub-cavities 121d, so that the water distribution in the water storage cavity 121a is relatively uniform, the fluctuation amplitude of the water flow in the water storage cavity 121a is reduced, and the vibration and noise of the balance device 10 are reduced; and, when the inner cylinder 20 rotates at a high speed, the sub-chamber 121d can prevent the water flow from floating upwards along the inner surface of the water storage chamber 121a, and prevent the water flow from flowing back into the annular water inlet 11b and splashing out.

In another embodiment, each partition plate 122 is provided with at least one water passing opening 122a to enable the plurality of sub-chambers 121d to be communicated in sequence, that is, each partition plate 122 can be provided with a water passing opening 122a respectively to enable the plurality of sub-chambers 121d to be communicated in sequence. That is, the partition 122 has a periphery that is hermetically coupled to the inner wall of the case 1211, and the water passing hole 122a is directly formed in the partition 122.

It is understood that when at least two partitions 122 are disposed in the water storage cavity 121a, a water passing hole 122a may be disposed on a portion of the partitions 122, and a portion of the edge of another portion of the partitions 122 is spaced from the inner wall of the case 1211 to form the water passing hole 122a.

In an embodiment, referring to fig. 10, the number of the partition plates 122 is at least two, and the water passing openings 122a corresponding to two adjacent partition plates 122 are arranged in a staggered manner. Because the water flow flows from the upper sub-chamber 121d to the lower sub-chamber 121d, the water passing openings 122a corresponding to the two adjacent partition plates 122 are arranged in a staggered manner, so that the flow path of the water flow and the residence time of the water flow in the water storage chamber 121a can be prolonged as much as possible.

In addition, in the embodiment of the water tank 121 provided with at least two partitions 122, the inlet 121b of the water tank 121 may also be disposed to be offset from the water passing opening 122a corresponding to the first partition 122 in the flow direction of the water flow, and/or the water passing opening 122a corresponding to the last partition 122 in the flow direction of the water flow may be disposed to be offset from the water discharging opening 121c. Thereby, the staying time of the water flow in the water storage chamber 121a can be also extended.

It can be understood that, when the water tank 121 is provided with only one partition 122 and one partition 122 divides the water storage cavity 121a into two sub-cavities 121d, the inlet 121b may be arranged to be staggered with respect to the water passing hole 122a corresponding to the partition 122, and/or the water outlet 121c may be arranged to be staggered with respect to the water passing hole 122a corresponding to the partition 122.

In one embodiment, referring to fig. 5, the water outlet 121c is located at the edge of the corresponding bottom wall of the water storage cavity 121a close to the radially inward side of the annular water guiding member 11, that is, the water outlet 121c may be located as far as possible on the side of the water storage cavity 121a close to the axis of the inner cylinder 20. When the inner cylinder 20 rotates, the water flow in the water storage cavity 121a is concentrated to the outside of the water storage cavity 121a by the centrifugal force, so that the position of the water outlet 121c is as close as possible to the edge of the radially inward side of the annular water guide 11, and the water flow in the water tank 121 can be reduced as much as possible flowing out from the water outlet 121c during the rotation of the inner cylinder 20, thereby further prolonging the staying time of the water flow in the water storage cavity 121 a.

In an embodiment, referring to fig. 7 and 11, the water passing openings 122a are located at the edge of the corresponding partition 122 close to the radially inward side of the annular water guiding member 11, that is, the water passing openings 122a may also be located as close as possible to the axial side of the water storage cavity 121a close to the inner cylinder 20, so that the water is prevented from flowing from the upper sub-cavity 121d to the lower sub-cavity 121d through the water passing openings 122a during the high-speed rotation of the inner cylinder 20.

In one embodiment, referring to fig. 4 and 5, a surface of the water tank 121 facing the inner cylinder 20 is attached to the inner cylinder 20. Specifically, in the embodiment where the water storage assembly 12 is disposed in the inner cylinder 20, the surface of the box 1211 facing the side of the inner cylinder 20 is attached to the inner surface of the inner cylinder 20, and in the embodiment where the water storage assembly 12 is disposed between the inner cylinder 20 and the outer cylinder 30, the surface of the box 1211 facing the side of the inner cylinder 20 is attached to the outer surface of the inner cylinder 20, so that the space occupied by the water tank 121 can be reduced.

In an embodiment, referring to fig. 4 and 5, in a top projection of the inner cylinder 20, a surface of the water tank 121 facing away from the inner cylinder 20 is shaped like an arc coaxial with the inner cylinder 20. Thereby, the space occupied by the water tank 121 can also be reduced.

When the surface of the water tank 121 facing one side of the inner cylinder 20 is attached to the inner cylinder 20, and the surface shape of the water tank 121 facing the radially outward side of the inner cylinder 20 is an arc shape coaxial with the inner cylinder 20, the structure of the water tank 121 can be more compact, and the space occupied by the water tank 121 can be greatly reduced.

In an embodiment, referring to fig. 5, 7, 10, and 12, the water tank 121 includes a tank 1211 and a plug 1213, the inlet 121b is located at a top end of the plug 1213, a bottom end of the plug 1213 is connected to a top end of the tank 1211, and a top end of the plug 1213 is in sealed insertion fit with the annular water guiding member 11. Specifically, the joint of the top end of the plug 1213 and the annular water guide member 11 may be bonded with a waterproof adhesive, or a sealing structure such as a sealing ring may be provided, so that the top end of the plug 1213 and the annular water guide member 11 are hermetically fitted to each other, thereby facilitating positioning of the water storage module 12 and preventing water in the water inlet channel 11a from leaking out of the joint of the plug 1213 and the annular water guide member 11.

In a specific embodiment, referring to fig. 7 and 12, a bottom wall corresponding to each water inlet channel 11a is provided with a water outlet 11c and a boss 11d surrounding the water outlet 11c, and the boss 11d extends into the inlet 121b of the corresponding plug 1213. The boss 11d not only can position the water storage unit 12, but also can further reduce the possibility that the water in the water inlet waterway 11a seeps out from the connection part of the water storage unit 12 and the annular water guide 11.

In an embodiment, referring to fig. 4, 5, and 7, the balancing apparatus 10 further includes a ring-shaped mounting plate 13 fixedly connected to the ring-shaped water guiding member 11, and at least a portion of the water storage assembly 12 is located at a radially inward side of the ring-shaped mounting plate 13 and fixedly connected to the ring-shaped mounting plate 13. The water storage assemblies 12 and the annular mounting plate 13 are fixedly connected through welding, bonding, fastening and the like, so that the annular mounting plate 13 can connect the plurality of water storage assemblies 12 and the annular water guide member 11 into a whole to play a role in preventing the water storage assemblies 12 from loosening.

In an embodiment, the water storage assemblies 12 are fixedly connected to the inner cylinder 20, for example, studs may be disposed on the water tank 121, screws may pass through the studs from a side of the water tank 121 away from the inner cylinder 20 and be fastened to the inner cylinder 20, and the water tank 121 may also be welded to the inner cylinder 20, thereby also preventing the water storage assemblies 12 from loosening.

In one embodiment, referring to fig. 13 to 15, the water injection assembly 40 includes a water inlet valve 41 and a plurality of water injection pipes 42, each of the water injection pipes 42 injects water toward a corresponding one of the annular water inlets 11b, and the water inlet valve 41 can selectively open or close a water path in each of the water injection pipes 42. That is, by providing the water inlet valve 41 and the plurality of water injection pipes 42, the controller can control the water injection assembly 40 to selectively inject water into the one or more annular water inlets 11b.

In an embodiment, referring to fig. 13 to 15, the outer tub 30 includes a tub 31 and a ring-shaped cover 32 located on the top of the tub 31, the ring-shaped cover 32 is located above the ring-shaped water guiding member 11, the ring-shaped water inlets 11b of all the water inlet waterways 11a are arranged on the top side of the ring-shaped water guiding member 11, the ring-shaped cover 32 is provided with an opening 32a penetrating through the ring-shaped cover 32, and the end of the water injection pipe 42 extends into the lower side of the ring-shaped cover 32 from the opening 32a and is aligned with the corresponding ring-shaped water inlet 11b. This arrangement facilitates both the arrangement of the water injection assembly 40 and the injection of water into the corresponding annular water inlet 11b by the water injection pipe 42.

In a specific embodiment, referring to fig. 15 and 16, the water injection pipe 42 has a water inlet passage 42a, and in a plane projection perpendicular to the water flow direction, the water inlet passage 42a located downstream of the water inlet valve 41 in the water flow direction includes a circular sub-passage 42b and a plurality of arc sub-passages 42c arranged at intervals along the circumference of the circular sub-passage 42b, and each arc sub-passage 42c is communicated with the circular sub-passage 42 b. The shape of the water inlet channel of the water injection pipe in the plane projection perpendicular to the water flow direction in the related art is generally circular, but for such a water injection pipe, after the water flows out from the water inlet channel, the water flow is in a conical divergent shape, so that the water flow is easily splashed into the adjacent annular water inlets and flows into the water storage assembly which does not need to be filled with water, whereas in the embodiment, after the water inlet channel 42a of the water inlet valve 41 downstream along the water flow direction is provided to include the circular sub-channel 42b and the plurality of arc sub-channels 42c arranged at intervals along the circumferential direction of the circular sub-channel 42b, the water flow gathering function can be performed, so that after the water flows out from the water inlet channel 42a, the water flow approximately flows in a columnar shape to the corresponding annular water inlet 11b and is not easily splashed into the adjacent annular water inlet 11b, thereby ensuring that the balancing device 10 can have a good balancing effect.
