A first aspect of the embodiments of the present application provides a balancing device 10 for laundry treatment equipment, please refer to FIG. 3 to FIG. 8 , comprising an annular water guide 11 and a plurality of water storage assemblies 12; the annular water guide 11 is used for On the top side of the inner cylinder 20 surrounding the clothes treating device, the annular water guide 11 has a plurality of water inlet channels 11a, and each water inlet channel 11a has an annular water inlet 11b for receiving the inlet water flow; a plurality of water storage components 12 is connected to the annular water guide member 11 and arranged along the circumferential direction of the annular water guide member 11. Each water storage assembly 12 includes a water tank 121, and the water tank 121 has a water storage cavity 121a, and an inlet 121b communicating with the water storage cavity 121a and The water outlet 121c, the water storage chamber 121a has a plurality of sub-chambers 121d arranged in layers in the vertical direction, the plurality of sub-chambers 121d are connected in sequence, the inlet 121b is communicated with the first sub-chamber 121d along the flow direction of the water flow, the water outlet 121c is communicated with the last sub-chamber 121d along the water flow direction; the inlet 121b of each water tank 121 is communicated with at least one water inlet channel 11a correspondingly.

A second aspect of the embodiments of the present application provides a barrel assembly 100, please refer to FIGS. 2, 3, 13 to 15, including an inner barrel 20, an outer barrel 30, a water injection assembly 40 and any embodiment of the present application The inner barrel 20 is rotatably arranged in the outer barrel 30, the annular water guide 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 along the circumferential direction of the inner barrel 20. Arrangement; the water injection assembly 40 is connected to the outer tub 30 to selectively inject water into one or more annular water inlets 11b.

A third aspect of the embodiments of the present application provides a laundry treatment device, please refer to FIG. 1 , including a casing 200 , a controller and the barrel assembly 100 of any embodiment of the present application; the barrel assembly 100 is disposed on the casing 200 Among them, the controller is electrically connected with the water injection assembly 40 to control the water injection assembly 40 to inject water into the annular water inlet 11b of the corresponding water inlet channel 11a.

It should be noted that, referring to FIGS. 13 to 15 , the controller can control the water injection assembly 40 to inject water into only one annular water inlet 11b at a time, or control the water injection assembly 40 to inject water into multiple annular water inlets 11b simultaneously.

The laundry treatment device may be an integration of any one or more of a clothes dryer, an all-in-one washer-dryer, a dehydrator, and a washing machine. The rotation axis of the inner tub 20 may be in a vertical direction, for example, the laundry treatment device may be a pulsator washing machine, and the rotation axis of the inner tub 20 may also be inclined at a certain angle relative to the vertical direction, for example, the clothes treatment device may be Agitator washing machine. The rotation center line of the balancing device 10 is substantially coincident with the rotation axis of the inner cylinder 20 , that is, the balancing device 10 can be arranged coaxially 20 with the inner cylinder.

In the washing stage, the rotation speed of the inner tub 20 is very low, for example, at 40 rpm, and it rotates intermittently, so there is no need to balance the inner tub 20, and therefore, the water storage chamber 121a does not need to be filled with water in the washing stage. That is to say, at the beginning of the dehydration stage, there is basically no water in the water tank 121, so that it is convenient to inject water into the corresponding water tank 121 according to the load eccentricity information of the inner cylinder during the dehydration stage.

The drain port 12b can be always open, or the drain port 12b can be selectively opened or closed. For example, during the washing stage, the drain port 12b can be kept closed to prevent the washing water from flowing back from the drain port 12b into the water storage assembly 12. middle. Before the dehydration phase begins, the drain 12b is in an open state so that substantially no water is stored in the water storage assembly 12 before dehydration begins.

Specifically, in the dehydration stage, the inner cylinder 20 initially rotates at a low speed. If the load eccentricity occurs in the inner cylinder 20, 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 1, the water injection assembly 40 injects water into the water tank 121 on the left side of FIG. Even when the rotation speed of the inner cylinder 20 is low, as long as the load eccentricity of the inner cylinder 20 occurs, 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 play a better role in the inner cylinder 20. Therefore, the balancing device 10 of the embodiment of the present application can play a better balancing effect on the inner cylinder 20 during the full rotation speed of the inner cylinder 20 .

In addition, since the water storage cavity 121a has a plurality of sub-chambers 121d which are arranged in layers in the vertical direction and communicated in sequence, when the water flows into the water storage cavity 121a, it needs to flow through the sub-chambers 121d in sequence before finally reaching the water outlet 121c , which is equivalent to prolonging the flow path and flow time of the water in the water storage cavity 121a. 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 Therefore, it takes a relatively long time for the water flow to flow out from the water outlet 121c after entering the water storage cavity 121a. It can be understood that, in the dehydration stage, the inner cylinder 20 is in the low speed stage for a short time, and the water flow is in the storage chamber 121c. The flow time in the water cavity 121a is sufficient for the inner cylinder 20 to pass the low-speed stage. Therefore, in the low-speed stage, the mass of the water injected into the water storage cavity 121a can basically act as a balancing mass, so that the balancing effect of the balancing device 10 is improved. better. After entering the high-speed stage, the water in the water storage cavity 121a is subject to a large centrifugal force, and is close to the radially outward inner surface of the water storage cavity 121a, and the water flow is not easy to flow downward under the action of gravity, thereby making the water storage cavity 121a. The water flow in 121a remains in the water storage cavity 121a, and will not be discharged from the drain port 121c, and the load eccentricity can be greatly balanced, which can effectively reduce the vibration and noise of the laundry treatment equipment during dehydration, and reduce the inner cylinder 20. reduce the risk of bucket collision and improve user experience.

Furthermore, dividing the water storage chamber 121a into a plurality of sub-chambers 121d can make the water volume distribution in the water storage chamber 121a relatively uniform, reduce the fluctuation amplitude of the water flow in the water storage chamber 121a, and reduce the vibration of the balancing device 10 itself. and noise; and, when the inner cylinder 20 rotates at a high speed, the sub-chamber 121d can block the water flow from floating upward along the inner surface of the water storage cavity 121a, preventing the water flow from entering the annular water inlet 11b and splashing out.

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

There are various positions for the annular water inlet 11b on the annular water guide 11 . In one embodiment, please refer to FIGS. 3 to 7 . The top side, thereby, can facilitate the water injection assembly 40 to inject water into the annular water inlet 11b. In other embodiments, the annular water inlets 11b of all the water inlet channels 11a may also be arranged on the radial side walls of the annular water guide 11 . Specifically, in the embodiment in which the water storage assembly 12 is arranged in the inner cylinder 20 Among them, the annular water inlets 11b of all the water inlet channels 11a are arranged on the radial inner side wall of the annular water guide 11. In the embodiment in which the water storage assembly 12 is arranged between the inner barrel 20 and the outer barrel 30, all inlets The annular water inlets 11b of the water channel 11a are all arranged on the radial outer side wall of the annular water guide 11, or, a part of the annular water inlets 11b of the water inlet 11a are arranged on the top side of the annular water guide 11, and the other part is The annular water inlet 11b of the water channel 11a is arranged on the radial side wall of the annular water guide 11 .

It should be noted that, in the embodiment in which the water storage assembly 12 is disposed between the inner barrel 20 and the outer barrel 30 , the annular water guiding member 11 surrounds the outer surface of the top end of the inner barrel 20 . In the embodiment in which the water storage assembly 12 is disposed in the inner barrel 20 , the annular water guide 11 surrounds the inner surface of the top end of the inner barrel 20 .

A plurality of water storage assemblies 12 can be connected to each other or arranged at intervals, but the water storage chambers 121a of each water storage assembly 12 are not connected, that is, the water in the water storage chambers 121a of one water storage assembly 12 cannot be into the water storage cavity 121a of the other water storage assembly 12 . In one embodiment, the plurality of water tanks 121 are evenly distributed along the circumferential direction of the annular water guiding member 11 , that is, the plurality of water tanks 121 are evenly distributed along the circumferential direction of the inner cylinder, thus, it is convenient for the inner cylinder 20 to appear during the rotation process. The load eccentricity is balanced and adjusted.

The water storage cavity 121a of each water storage assembly 12 may be communicated with only one water inlet water channel 11a, or may be communicated with two or more water inlet water channels 11a, but each water inlet water channel 11a is only connected with one water storage channel 11a. The water storage chambers 121a of the components 12 are connected, that is to say, each water inlet channel 11a can only supply water to the water tanks 121 of one water storage component 12, and cannot supply water to the water tanks 121 of multiple water storage components 12 at the same time.

In one embodiment, please refer to FIGS. 7 to 9 , the water storage assembly 12 further includes at least one partition 122 disposed in the water storage cavity 121a, and all the partitions 122 divide the water storage cavity 121a into vertical layers. A plurality of sub-chambers 121d are provided, and the plurality of sub-chambers 121d communicate with each other through a water passage. That is to say, the partitions 122 are arranged approximately in the horizontal direction, and when there are multiple partitions 122 , the multiple partitions 122 are arranged approximately in parallel and at intervals.

The way of forming the water passage is not limited. For example, in one embodiment, a part of the edge of each partition 122 is spaced from the inner wall of the box 1211 to form the water passage 122a, so that the plurality of sub-chambers 121d are communicated in sequence.

In another embodiment, each partition 122 is provided with at least one water passage 122a so that the plurality of sub-chambers 121d are communicated in sequence. The chambers 121d can communicate in sequence. That is to say, the periphery of the partition plate 122 is connected to the inner wall of the box body 1211 in a sealed manner, and the water passage 122a is directly disposed on the partition plate 122 .

It can be understood that when at least two partitions 122 are provided in the water storage cavity 121a, a part of the partitions 122 may be provided with a water passage 122a, and a part of the edge of another part of the partitions 122 may be spaced from the inner wall of the box 1211 to form the water passage 122a.

In one embodiment, please refer to FIG. 8 , the number of partitions 122 is at least two, and the water passages 122 a corresponding to two adjacent partitions 122 are arranged in a staggered manner. Since the water flow flows from the upper sub-chamber 121d to the lower sub-chamber 121d, staggering the water passages 122a corresponding to the two adjacent partitions 122 can extend the flow path of the water flow as much as possible and extend the water flow in the water storage space. Residence time in cavity 121a.

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 arranged staggered from the water passage 122a corresponding to the first partition 122 along the water flow direction, and/or, The water passage 122a corresponding to the last baffle 122 along the water flow direction is arranged staggered from the water outlet 121c. Therefore, the residence time of the water flow in the water storage chamber 121a can also be prolonged.

It can be understood that, when the water tank 121 is provided with only one partition plate 122, and one partition plate 122 divides the water storage cavity 121a into two sub-chambers 121d, the inlet 121b can also be arranged in a staggered arrangement with the water passage 122a corresponding to the partition plate 122. , and/or, the water outlet 121c and the water passage 122a corresponding to the partition plate 122 are arranged staggered.

When the inner cylinder 20 rotates, the water flow in the water storage cavity 121a will be concentrated to the outside of the water storage cavity 121a under the action of centrifugal force. Therefore, the water outlet 121c should be arranged as close as possible to the annular water guide member 11 and radially inward. At the edge of the side, during the rotation of the inner cylinder 20, the flow of water in the water tank 121 from the water outlet 121c can be reduced as much as possible, thereby further prolonging the residence time of the water in the water storage cavity 121a.
