Referring to fig. 1 to 5, the balance assembly 100 of the present invention may be used in a household appliance 1000 (see fig. 10), the balance assembly 100 includes a balance ring 10 and a water injection member 20, a chamber 11 is circumferentially disposed in the balance ring 10 along the balance ring 10, the balance ring 10 has a rotation axis L, the balance ring 10 includes a first surface 12 and a second surface 13 connected to each other, the first surface 12 is a balanced inner peripheral surface and faces the rotation axis L, the first surface 12 has a water inlet 121, the water inlet 121 communicates with the chamber 11, the second surface 13 has a water outlet 131, and the water outlet 131 communicates with the chamber 11. The water injection member 20 is provided with a water injection hole 221, the water injection hole 221 being opposite to the water inlet 121, wherein the second face 13 satisfies at least one of the following conditions:

1) the second face 13 is perpendicular to the first face 12;

2) the second face 13 is opposite to the first face 12.

The utility model discloses embodiment's balanced subassembly 100 can be through the effect of water injection spare 20 and water inlet 121 water injection in order to realize adjusting balance in chamber 11 to accessible delivery port 131 outwards discharges water, and the accessible is rationally adjusted into drainage speed like this, realizes the in-process drainage of running at a high speed, and then adapts to the washings and dewaters the situation that leads to eccentric constantly changing at the in-process of running at a high speed, has promoted the damping effect effectively.

Specifically, in the embodiment of the present invention, the household electrical appliance 1000 may be an electrical appliance having a rotation function, such as a clothes treatment apparatus, and the clothes treatment apparatus may be a washing machine, a clothes dryer or a washing and drying all-in-one machine.

Referring to fig. 9, in an example, the household appliance 1000 may further include a body 200 and a cavity 300, the cavity 300 may be rotatably disposed in the body 200, the cavity 300 may be used for placing laundry, and the laundry may include laundry to be washed, dehydrated, or dried. The balance ring 10 of the balance assembly 100 is connected to the cavity 300 and can rotate with the cavity 300, and the rotation axis L of the balance ring 10 is parallel to or coincident with the rotation axis M of the cavity 300. The water injection member 20 may be mounted on the body 200. When the cavity 300 drives the balance ring 10 to rotate, the water injection member 20 can be stationary, which not only facilitates the manufacturing and installation, but also realizes more stable water injection.

When the cavity 300 of the household appliance 1000 rotates at a high speed, the balance ring 10 rotates along with the cavity 300, and at this time, water can be injected into the cavity 11 of the balance ring 10 through the water injection member 20 and the water inlet 121 to perform balance adjustment on the cavity 300 so as to avoid the eccentric condition of the cavity 300 caused by uneven dispersion of washings in the cavity 300, thereby avoiding the vibration caused by collision or friction between the cavity 300 and the body 200 and other parts.

In addition, in the rotating process of the cavity 300, water in the cavity 11 can move to other positions of the cavity 11 under the action of centrifugal force, on one hand, water can not flow out of the water inlet 121, and on the other hand, water can be discharged from the water outlet 131, so that under the condition that the water outlet speed of the water outlet 131 is basically kept unchanged, the water quantity in the cavity 11 can be adjusted by adjusting the water inlet speed of the water injection piece 20, and the water injection device further adapts to the condition that the eccentricity of washed objects in the cavity 300 is continuously changed due to dehydration in the high-speed rotating process, so that the cavity 300 can also keep balanced operation in the high-speed rotating process, and the vibration reduction effect is effectively improved.

In the embodiment shown in fig. 1, the first surface 12 is an inner wall surface of the chamber 11 facing the rotation axis L, and the second surface 13 is an outer wall surface connected to the inner wall surface of the chamber 11. In the embodiment shown in fig. 3, the second surface 13 on which the water outlet 131 is opened is an outer wall surface perpendicular to the inner circumferential surface of the chamber 11. In the embodiment of fig. 1, the second surface 13 on which the water outlet 131 is opened is an outer peripheral surface opposite to the inner peripheral surface. In other embodiments, the second surface 13 may be an outer peripheral surface opposite to the inner peripheral surface and an outer wall surface perpendicular to the inner peripheral surface, and both surfaces are provided with the water outlet 131.

It can be understood that, in the embodiment of the present invention, when the balance ring 10 stops rotating, the water injection member 20 stops injecting water, the centrifugal force in the chamber 11 is lost, and water can be rapidly discharged from the water inlet 121 and/or the water outlet 131 of the chamber 11 under the action of gravity.

Referring to fig. 1, 2 and 5, in some embodiments, the water inlet 121 is arc-shaped, the water outlet 131 is circular, and the area of the water inlet 121 is larger than that of the water outlet 131.

Thus, when the balance ring 10 rotates, the arc-shaped water inlet 121 can more conveniently inject water into the cavity 11 through the water injection member 20. Meanwhile, the water outlet 131 is circular and the area of the water inlet 121 is larger than that of the water outlet 131, so that the influence of excessive water discharge in the chamber 11 to the balance function of the balance ring 10 due to the excessive area of the water outlet 131 can be prevented.

In some embodiments, the diameter of the outlet 131 ranges from (1.8mm, 10.5 mm).

Thus, the area of the water outlet 131 is not too small to cause too slow water outlet, nor too large to cause too fast water outlet.

Specifically, in some examples, the diameter of the outlet 131 may be 1.8mm, 2.8mm, 3.8mm, 4.8mm, 5.8mm, 6.8mm, 7.8mm, 10.5mm, or other values between 1.8mm and 10.5 mm.

Referring to fig. 5-8, in some embodiments, the balance ring 10 defines a plurality of spaced chambers 11.

In this way, the water can be introduced into the chambers 11 corresponding to the water inlets 121 through the different water inlets 121 to control the amount of water injected into the plurality of chambers 11, thereby achieving balance control, and further improving the balance ability of the balance ring 10.

Specifically, the first surface 12 is provided with a plurality of water inlets 121, and the second surface 13 is provided with a plurality of water outlets 131 (see fig. 7). Each chamber 11 communicates with a corresponding one of the water inlet 121 and the water outlet 131. In the embodiment of fig. 5 to 8, the second surface 13 is opposite to the first surface 12, and the second surface 13 is an outer peripheral surface of the gimbal. The plurality of cavities 11 can be distributed along the circumferential direction of the balance ring 10, so that no matter which direction the cavity 300 of the household appliance 1000 is eccentric, the required water quantity can be injected into the corresponding cavity 11 through the water injection piece 20 to adjust the balance direction of the balance ring 10, the water injection is more targeted, the balance response to load eccentricity is quicker, and the adjustment efficiency is higher.

It will be appreciated that in such an embodiment, the number of the water injection holes 221 of the water injection member 20 corresponds to the number of the water inlet ports 121, that is, one water injection hole 221 is provided for each water inlet port 121, so that when water needs to be injected into any one or more of the plurality of chambers 11, only water needs to be injected into the corresponding water inlet port 121 through the corresponding water injection hole 221.

Further, referring to fig. 5 to 8, in some embodiments, three chambers 11 are formed in the balance ring 10 at intervals, the second surface 13 is opposite to the first surface 12, the second surface 13 is formed with three water outlets 131, the first surface 12 is formed with three water inlets 121, each chamber 11 is communicated with one corresponding water inlet 121 and one corresponding water outlet 131, and the three water outlets 131 are uniformly arranged along the circumferential direction of the balance ring 10.

Like this, set up in the compensating ring 10 and have three spaced cavity 11, three delivery port 131 evenly sets up along the circumference of compensating ring 10, can make the compensating ring 10 rotate the in-process like this, and the water in the three cavity 11 all can be through the steady and even outflow of delivery port 131 that corresponds. Meanwhile, the second surface 13 is opposite to the first surface 12, and rotates on the balance ring 10, and water in the chamber 11 is gathered on the second surface 13 under the action of centrifugal force, so that the water outlet 131 of the second surface 13 basically has water to flow out and the flow rate is basically unchanged, and then the water quantity in the chamber 11 can be adjusted only by adjusting the water injection speed of the water injection hole 221, so that the accurate control of the water quantity is realized to enable the balance ring 10 to balance the eccentric condition of the cavity 300 in time.

Specifically, referring to fig. 5 to 8, the three chambers 11 are uniformly arranged along the circumferential direction of the balance ring 10. Three water inlets 121 are correspondingly arranged in the three chambers 11, and the three water inlets 121 are uniformly arranged along the axial direction of the balance ring 10 at intervals and are not interfered with each other. In this way, water can be fed into the corresponding chamber 11 through the three different water inlets 121, so that precise control of the water amount is realized.

It is understood that in such an embodiment, the number of the water injection holes 221 is also three, three water injection holes 221 correspond to three water inlets 121, and one or more of the three chambers 11 may be injected with water through the corresponding water injection holes 221 and water inlets 121, respectively, so that the balance control may be implemented by controlling the amount of water injected in the three chambers 11.

It should be noted that, in some embodiments, the number of the corresponding water inlets 121 of each chamber 11 may be one or more. The number of the water outlets 131 corresponding to each chamber 11 may be one or more, and the number of the water injection holes 221 corresponding to each water inlet 121 may be 1 or more, and is not limited herein.

Referring to fig. 5 to 8, in some embodiments, the first surface 12 is provided with a water channel groove 122 extending along the circumferential direction of the balance ring 10, a groove wall of the water channel groove 122 is provided with an opening 1221, the notch 1222 of the water channel groove 122 is the water inlet 121, and the opening 1221 communicates the water inlet 121 and the chamber 11.

Thus, the control of the water injection amount of the chamber 11 can be realized by controlling the water injection amount of the water channel groove 122, when the chamber 11 needs to be injected with a required water amount, the water injection member 20 can inject the required water amount into the notch 1222 of the water channel groove 122, and the water can flow into the water channel groove 122 to enter the chamber 11 through the opening 1221, so that the control of the water amount in the chamber 11, which is influenced by the water splashing from the balance ring 10 due to the excessive water flow during water injection, can be avoided. In addition, the water channel groove 122 extends along the circumferential direction of the balance ring 10, so that the balance ring 10 can stably flow into the chamber 11 through the water channel groove 122 when rotating.

Specifically, in the illustrated embodiment, the number of the chambers 11 is three, and one water channel groove 122 may be respectively disposed on the first surface 12 of each chamber 11, that is, the number of the water channel grooves 122 is three, and the three water channel grooves 122 respectively extend along the circumferential direction of the balance ring 10 and are arranged along the axial direction of the balance ring 10. The three notches 1222 (i.e., the water inlets 121) of the three water passage grooves 122 correspond to the three water injection holes 221, respectively, and the three openings 1221 of the three water passage grooves 122 communicate with the corresponding chambers 11 and the corresponding notches 1222, respectively. Like this, the control to the water injection volume of three cavity 11 can be realized through the water injection volume of controlling three water channel groove 122, when the required water yield of needs to corresponding cavity 11 injection, can inject the required water yield to corresponding water channel groove 122 through water injection spare 20, and the water injection is more pertinent, and is faster to the eccentric balanced response of load, and eccentric regulation efficiency is higher.

It is understood that in some embodiments, the number of the chambers 11 and the water channel grooves 122 is not limited to three, and the number of the chambers 11 and the water channel grooves 122 may also be set to other values, such as two, four, or more than four, according to the requirements of balance control, manufacturing process, and the like. In some embodiments, the chambers 11 and the water channel 122 may be in the same number and correspond to each other one by one, or in different numbers and correspond to each other one by one.

For example, in one example, the number of the water channel grooves 122 may be greater than the number of the chambers 11, some of the chambers 11 are respectively communicated with one water channel groove 122, and other chambers 11 are respectively communicated with at least two water channel grooves 122, that is, the water channel grooves 122 and the chambers 11 are in a many-to-one relationship. For another example, in some examples, the number of the water passage grooves 122 is greater than the number of the chambers 11, the plurality of water passage grooves 122 includes a dedicated water passage groove 122 communicating with only one chamber 11 and a common water passage groove 122 communicating with at least two chambers 11, and each chamber 11 may have a dedicated water passage groove 122 communicating with the chamber 11. Therefore, when water needs to be injected into one chamber 11, water injection into the corresponding special water channel groove 122 can be controlled, water is not injected into the other special water channel grooves 122 and the common water channel groove 122, and when water needs to be injected into at least two chambers 11, water injection into the corresponding special water channel groove 122 can be controlled, and water injection into the common water channel groove 122 communicated with the at least two chambers 11 which need to be injected with water can also be controlled.

Furthermore, in the illustrated embodiment, the three chambers 11 are of the same volume and shape, which not only facilitates manufacturing, but also facilitates balance adjustment. When the number of chambers 11 is other, the plurality of chambers 11 may still be provided with the same volume and the same shape. Of course, each chamber 11 may be configured to have different volumes and shapes according to the requirement, and is not limited in particular.

It will also be appreciated that in some embodiments, the size of the opening 1221 of each waterway slot 122 may be the same or different. For example, the size of the openings 1221 of the water passage grooves 122, which are sequentially arranged at intervals in the axial direction of the balance ring 10, is gradually increased or decreased, or is increased and then decreased, and is not particularly limited. Additionally, in some embodiments, the dimensions of the notch 1222 (i.e., the water inlet 121) of each channel 122 may be the same or different. For example, the size of the notches 1222 of the water passage grooves 122, which are sequentially spaced in the axial direction of the balance ring 10, is gradually increased or decreased, or is increased and then decreased, and is not particularly limited.

In the embodiment shown in the figures, three openings 1221 are opened in each water channel groove 122. It is understood that in some embodiments, the number of the openings 1221 of each water channel groove 122 may be other values, such as one, two, four or more, and is not particularly limited. In addition, in some embodiments, when two or more openings 1221 are provided for each water channel groove 122, the size of each opening 1221 may be the same or different, and is not limited in particular.

Referring to fig. 1 and 2, in some embodiments, the water injection member 20 is arc-shaped, the water injection member 20 includes a water inlet surface 21 and a water injection surface 22, the water injection surface 22 is opposite to the first surface 12, the water inlet surface 21 is connected to the water injection surface 22 and is perpendicular to the rotation axis L, the water injection surface 22 is provided with water injection holes 221, the water inlet surface 21 is provided with water inlet holes 211, and the water inlet holes 211 are communicated with the water injection holes 221.

Specifically, the water injection member 20 is arc-shaped, the water injection surface 22 is also arc-shaped, and the water inlet 121 is also arc-shaped, so that the water injection surface 22 corresponds to the water inlet 121, and the water injection hole 221 on the water injection surface 22 facilitates water injection to the water inlet 121. The water injection surface 22 is opposite to the first surface 12, and the first surface 12 faces the rotation axis, that is, the water injection surface 22 may also face the rotation axis L, and the water inlet surface 21 is perpendicular to the rotation axis L, that is, the water inlet surface 21 may be perpendicular to the water injection surface 22 or at a certain angle. The water inlet channel is opened in the water injection part 20, and the water inlet channel is communicated with the water inlet 121 and the water injection hole 221, and in some embodiments, the water inlet channel can be in an L shape, so that the water inlet 121 and the water injection hole 221 on the water inlet surface 21 and the water injection surface 22 which are perpendicular to each other or at a certain angle can be communicated through two water inlet sections which are bent relatively. It is understood that in some embodiments, the shape of the water inlet channel inside the water injection member 20 may be other forms, for example, the water inlet channel may be a broken line or a circular arc, which is not limited herein.

In the illustrated embodiment, the number of the water injection members 20 is one, the number of the chambers 11 and the water inlets 121 is three, and three water injection holes 221 corresponding to the three water inlets 121 are formed in the single water injection member 20, that is, in the illustrated embodiment, the water injection members 20 are in a one-to-many manner with the chambers 11 and the water inlets 121. It will be appreciated that in some embodiments, the water injection member 20 may be in one-to-one or many-to-one relationship with the chamber 11 and the water inlet 121. For example, each chamber 11 and the water inlet 121 can correspond to one water injection member 20, and each chamber 11 and the water inlet 121 are separately injected with one water injection member 20. As another example, each chamber 11 and inlet 121 may correspond to a plurality of water injection members 20, and each chamber 11 and inlet 121 may be filled with one or more of the plurality of water injection members 20 corresponding thereto.

In addition, in the rotating process of the cavity 300, water in the cavity 11 moves towards the second surface 13 of the cavity 11 under the action of centrifugal force, on one hand, the water cannot flow out of the water inlet 121, and on the other hand, the water can be discharged from the water outlet 131 on the second surface 13, so that under the condition that the water outlet speed of the water outlet 131 is basically kept unchanged, the water quantity in the cavity 11 can be adjusted by adjusting the water inlet speed of the water injection piece 20, the effect that the water quantity in the cavity 11 is always controlled to be equal to the eccentric mass is achieved, the condition that the eccentricity of washings in the cavity 300 is continuously changed due to dehydration in the high-speed rotating process is further adapted, the cavity 300 can also keep balanced operation in the high-speed rotating process, and the vibration damping effect is effectively improved.

The rotation axis L of the balance ring 10 is parallel to or coincides with the rotation axis M of the cavity 300, that is, the balance ring 10 may be disposed coaxially with the cavity 300 or may be disposed eccentrically in parallel with respect to the cavity 300, and in the illustrated embodiment, the rotation axis L of the balance ring 10 coincides with the rotation axis M of the cavity 300. It can be understood that, in order to ensure that the balance ring 10 has a good balance effect on the cavity 300, when the balance ring 10 is eccentrically disposed in parallel, the value of the eccentric distance may be smaller, for example, in some embodiments of the present invention, the distance between the rotation axis L of the balance ring 10 and the rotation axis L of the cavity 300 may be set to be less than 6mm, for example, 3mm, 4mm, etc.

specifically, the mounting body 202 is fixedly connected with the housing 201 through the vibration damping structure 400, the cavity 300 and the balancing assembly 100 are mounted in the mounting body 202, the mounting body 202 is formed with a water containing chamber 203, the water outlet 131 of the balancing assembly 100 is communicated with the water containing chamber 203, and water flowing out of the water outlet 131 can flow into the water containing chamber 203.

In some embodiments, the household appliance 1000 may further include a drainage structure connected to the mounting body 202, the drainage structure being used for draining water in the water containing chamber 203 to the outside of the household appliance 1000 or directly conveying water in the water containing chamber 203 further back to the water injection member 20 to realize circulating inflow water, so as to realize recycling of water resources.

For example, in one example, the water flow in the water containing chamber 203 may be discharged by the drain pump through the drain line by providing the drain pump and the drain line, the drain line communicating the water containing chamber 203 and the outside of the home appliance 1000. For another example, in one example, the drainage structure may include a drainage pump and a delivery line, the delivery line may connect the water injection member 20 and the water containing chamber 203, and the drainage pump case delivers the water in the water containing chamber 203 back into the water injection member 20 through the delivery line to inject the chamber 11, thereby achieving circulation of the water.

It can be understood that the water inlet 121 of the balancing ring 10 is also communicated with the water containing chamber 203, so that when the balancing ring 10 stops rotating, the water injection member 20 stops injecting water, the water in the chamber 11 loses the effect of centrifugal force, and the water can be rapidly discharged from the water inlet 121 or the water outlet 131 of the chamber 11 into the water containing chamber 203 under the effect of gravity.
