Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and more specifically, to a balancing component and a household appliance. Background Art

[0002] In household appliances, high-speed rotation of the cavity can easily lead to uneven load distribution within the cavity. For example, during the spin cycle of a washing machine, the laundry in the washing unit is unevenly distributed and eccentric. When the washing unit rotates at high speed, it generates significant vibration. Therefore, a balancing ring is often used to balance the eccentric mass and reduce vibration. Specifically, the balancing ring is usually equipped with a balancing weight, which can be moved to offset or reduce the vibration and noise of the cavity.

[0003] In related art, a drive device is mounted on a balancing weight to drive the weight's movement. When the weight moves, the drive device also moves with the weight. However, when the cavity of a household appliance (such as the inner drum of a washing machine) is running at high speed, the drive device is easily affected by centrifugal force, resulting in the drive device being unable to smoothly drive the weight's movement.

Of course, they are merely examples, and the purpose is not to limit this application.

[0063] See also Figure 1-Figure 3 The balancing assembly 100 of the embodiment of the present application can be used in a household appliance 1000. The household appliance 1000 includes a balancing assembly 100, a first cavity 200, and a second cavity 300.

[0064] The first cavity 200 is rotatably connected to the second cavity 300, and the first cavity 200 can be used to place a load. The balancing assembly 100 includes a balancing body 10 and a balancing weight 20. The balancing body 10 is mounted in the first cavity 200. An annular chamber 13 is provided within the balancing body 10, and the balancing weight 20 is located within the chamber 13. The balancing weight 20 can rotate within the chamber 13 around the central axis Y of the chamber 13. The household appliance 1000 can be a laundry appliance such as a washing machine or a dryer, or other household appliance 1000 having a rotatable first cavity 200. The load can be items that need to be washed, such as clothing and quilts, or other items.

[0065] Understandably, Figure 1In the illustrated embodiment, the first cavity 200 is rotatably positioned within the second cavity 300. When the household appliance 1000 is operating, the first cavity 200 rotates within the second cavity 300. This can easily lead to uneven load distribution within the first cavity 200, resulting in eccentricity. For example, when a washing machine is spinning clothes, the uneven distribution of the load can easily cause the first cavity 200 to rotate eccentrically. Consequently, when the eccentric first cavity 200 rotates at high speed, the household appliance 1000 can generate significant vibration. The balancing body 10 is attached to and fixed to the first cavity 200, rotating with it. Therefore, by controlling the movement of the balancing weight 20 within the balancing body 10, the eccentric mass of the first cavity 200 can be offset or reduced by the weight and centripetal force of the balancing weight 20 during rotation, thereby reducing vibration in the household appliance 1000.

[0066] It can be understood that in other embodiments, the first cavity 200 and the second cavity 300 can be connected in other ways, and are not limited to the first cavity 200 being able to be rotatably located in the second cavity 300. As long as the first cavity 200 can be rotated relative to the second cavity 300, no specific limitation is made here.

[0067] In the example of the present application, the household appliance 1000 is a washing machine that can be used to wash clothes, and the clothes can be placed in the first cavity 200. The first cavity 200 is a washing cavity (inner barrel), and the second cavity 300 can be a water storage cavity (outer barrel). The water storage cavity and the washing cavity are both cylindrical, and the washing cavity can be rotatably arranged in the water storage cavity. The water storage cavity and the washing cavity can be arranged in the housing (not shown) of the household appliance 1000. The washing cavity can have a rotation axis X that is set horizontally, inclined or vertically. In other words, the rotation axis X of the washing cavity is parallel to, inclined to, or perpendicular to the horizontal plane relative to the horizontal plane. It can be understood that one or more balancing bodies 10 can be set at any position in the washing cavity, and the balancing body 10 rotates with the rotation of the washing cavity. The central axis Y of the chamber 13 is parallel to or coincides with the rotation axis X of the washing cavity, that is, the balancing body 10 can be set coaxially with the washing cavity, or can be set eccentrically relative to the washing cavity. The balancing body 10 can also be arranged on the washing chamber in a spiral shape.

[0068] In addition, please combine Figure 2 To further reduce the transmission of vibrations from within the washing machine to the outside, the water chamber can be connected to a mounting plate 400 via a vibration-damping structure. Mounting plate 400 can be fixed to, or be the bottom plate of, the housing. The vibration-damping structure can utilize springs, hydraulic components, and other structural elements to reduce vibration transmission.

[0069] See also Figure 1 and Figure 2Household appliance 1000 is a drum washing machine. The first cavity 200 includes a first end 201 and a second end 202 along the rotation axis X. A balancing body 10 is connected to each of the first and second ends 201, 202. Each balancing body 10 has at least one balancing weight 20 disposed within its cavity 13, for example, one, two, or more. Preferably, two balancing weights 20 are disposed within the cavity 13 of the balancing body 10. The two balancing weights 20 are initially arranged symmetrically. This arrangement ensures that the two balancing weights 20 do not introduce additional vibration into the first cavity 200.

[0070] Specifically, the second end 202 of the first cavity 200 is fixedly connected to the fixing frame 500, the fixing frame 500 can be connected to a rotating shaft (not shown), and the power device (not shown) of the household appliance 1000 can be connected to the rotating shaft to drive the first cavity 200 to rotate. Figure 2 In the illustrated embodiment, the first end 201 of the first cavity 200 is the front end, and the second end 202 is the rear end. The front end may refer to the end facing the user. In other embodiments, the balancing body 10 may be disposed at either the first end 201 or the second end 202 of the first cavity 200, or between the first end 201 and the second end 202. The mounting bracket 500 may be a tripod.

[0071] In the embodiment of the present application, the balancing body 10 is annular and can be referred to as a balancing ring. It is understood that in other embodiments, the balancing body 10 can be in other shapes, such as a plate, a square ring, an elliptical ring, etc., which are not specifically limited here.

[0072] See also Figure 1 and Figure 3 The balancing body 10 includes a first ring body 11 and a second ring body 12, which are connected and together form a sealed chamber 13, in which a balancing weight 20 is arranged. Since the balancing body 10 is annular and the chamber 13 is also annular, the balancing weight 20 can rotate around the central axis Y of the chamber 13 in the chamber 13 of the balancing body 10, that is, perform a circular motion in the chamber 13. In the illustrated embodiment, the first ring body 11 can be referred to as the balancing ring body, and the second ring body 12 can be referred to as the end cover. It should be noted that the central axis Y of the chamber 13 can be understood as the axis passing through the geometric center of the annular chamber 13.

[0073] See also Figure 3-Figure 5 In this embodiment, the balancing assembly 100 further includes a transmission component 30 and a power component 40 .

[0074] The power component 40 is fixedly connected to the balancing body 10, and the balancing weight 20 is connected to the transmission member 30. The transmission member 30 is arranged in the chamber 13 and can rotate around the central axis Y of the chamber 13 in the chamber 13. The power component 40 is configured to drive the transmission member 30 to rotate in the chamber 13, thereby driving the balancing weight 20 to rotate around the central axis Y in the chamber 13. In this way, in the process of controlling the movement of the balancing weight 20, the power component 40 will not move with the movement of the balancing weight 20. The power supply method of the power component 40 does not require brushes, but can adopt a direct wire power supply method, which greatly improves the power supply reliability and stability. It should be noted that in the embodiment of the present application, the balancing weight 20 can be directly fixed on the transmission member 30, or it can be installed on the transmission member 30 through other components. In addition, in the embodiment of the present application, the balancing weight 20 can also be configured to be able to move a certain distance relative to the transmission member 30, and it only needs to drive the balancing weight 20 to move together when the transmission member 30 rotates. Figure 3-5 In the embodiment shown, the balancing weight 20 can be directly fixed on the transmission member 30 by screws. It can be understood that in other embodiments, the balancing weight 20 can also be installed on the transmission member 20 through other connecting elements. The balancing weight 20 can move relative to the connecting element, and the transmission member 30 can drive the balancing weight to move through the connecting element.

[0075] Specifically, please combine Figure 3-Figure 6 In this embodiment, the power component 40 includes a driving member 41 and a rotating member 42. The driving member 41 is fixedly connected to the balancing body 10, and the rotating member 42 connects the driving member 41 and the transmission member 30. The driving member 41 is configured to drive the rotating member 42 to rotate to drive the transmission member 30 to rotate in the chamber 13.

[0076] It should be noted that, in this article, fixed connection can be understood as the two being directly fixedly connected together or being fixedly connected together through other components. For example, in this embodiment, the fixed connection between the driving member 41 and the balancing body 10 can be that the driving member 41 is directly fixedly installed on the balancing body 10 or is fixedly installed on the balancing body 10 through other components, and the two are relatively fixed.

[0077] The driving member 41 can be a motor and electrically connected to a balancing control board (not shown). The balancing control board includes a balancing controller that controls the motor to drive the transmission member 30 to rotate, thereby driving the balancing weight 20 to perform circular motion about the central axis Y within the chamber 13 of the balancing body 10. In one embodiment, the rotating member 42 includes a gear, with the motor shaft of the motor connected to the gear. A toothed portion 301 is provided on the side of the transmission member 30 near the central axis Y of the chamber 13, and the gear meshes with the toothed portion 301.

[0078] Specifically, in such an embodiment, the transmission member 30 can be a ring gear with an annular tooth portion 301 on the inner side. The motor drives the ring gear through the gear to rotate around the central axis Y of the chamber 13 in the chamber 13 of the balancing body 10, thereby driving the balancing weight 20 to rotate around the central axis Y of the chamber 13 in the chamber 13.

[0079] It can be understood that the power component 40 drives the transmission member 30 by meshing the gear with the tooth portion 301. The meshing has the characteristics of high precision and stable transmission, and there is no risk of slipping. In addition, the gear and the tooth portion 301 on the transmission member 30 that is located on the side close to the central axis Y of the chamber 13 engage with each other, which can avoid the centrifugal force generated when the first cavity 200 of the household appliance 1000 rotates at high speed, causing the meshing to be too tight and causing resistance, thereby ensuring that when the first cavity 200 rotates at high speed, the balance block 20 moves stably in the chamber 13.

[0080] In the illustrated embodiment, only one gear meshes with the tooth portion 301. This allows only one annular tooth portion 301 to be provided on the inner wall of the transmission member 30, and both the gear and the tooth portion 301 are single, thus saving costs. In other embodiments, the number of gears may be two or another number, and the number of tooth portions 301 may be adjusted based on actual needs.

[0081] In addition, in the illustrated embodiment, the power component 40 may further include a speed regulating mechanism 43, which connects the rotating member 42 to the output shaft of the driving member 41. The speed regulating mechanism 43 can adjust the transmission ratio between the driving member 31 and the rotating member 42, thereby adjusting the rotational speed of the rotating member 42. Specifically, the speed regulating mechanism 43 may include at least two connected gears, and the at least two gears may include a duplex gear.

[0082] In some embodiments, the transmission member 30 is annular, a tooth portion 301 is formed on the inner side of the transmission member 30 , and the outer side of the transmission member 30 contacts the inner wall 131 of the chamber 13 .

[0083] In this way, the outer side of the transmission member 30 abuts against the inner wall 131 of the chamber 30 , so that the transmission member 30 can stably rotate in the chamber 13 .

[0084] Furthermore, in such an embodiment, the balancing assembly 100 may also include a rolling member, which may be arranged between the inner wall 131 of the chamber 13 and the outer side of the transmission member 30. When the transmission member 30 rotates, the rolling member rotates between the inner wall 131 of the chamber 13 and the outer side of the transmission member 30.

[0085] In this way, the provision of the rolling element can reduce the friction between the transmission element 30 and the balancing body 10, improve the stability of the rotation, and bear the centrifugal force generated when the transmission element 30 rotates. Specifically, in such an embodiment, there are multiple rolling elements, and the multiple rolling elements are evenly spaced along the circumference of the transmission element 30. In this way, the centrifugal force of the transmission element 30 can be evenly borne and the stable rotation of the transmission element 30 can be ensured.

[0086] See also Figure 3-Figure 7 In some embodiments, the balancing assembly 100 may further include a guide structure 50 that connects the balancing body 10 and the transmission member 30. The guide structure 50 is configured to guide the transmission member 30 to rotate within the chamber 13 about the central axis Y of the chamber 13. In this way, the guide structure 50 can guide the rotation of the transmission member 30 and the balancing weight 20, thereby allowing the transmission member 30 and the balancing weight 20 to stably and smoothly perform circular motion within the chamber 13 about the central axis Y of the chamber 13, thereby achieving the purpose of balancing the eccentric mass.

[0087] See also Figure 3-Figure 7 The guide structure 50 includes a first connecting member 51 and a second connecting member 52 . The first connecting member 51 is disposed in the chamber 13 and fixedly connected to the balancing body 10 .

[0088] In the illustrated embodiment, the driving member 41 of the power component 40 is fixedly connected to the first connecting member 51, thereby achieving a fixed connection with the balancing body 10. Specifically, the power component 40 is fixedly mounted to the first connecting member 51 via a first fixing member 60. The first fixing member 60 can be plate-shaped. The driving member 41 of the power component 40 can be mounted on one end of the first fixing member 60, and the first connecting member 51 can be mounted on the other end of the other side of the first fixing member 60. In other words, the driving member 41 and the first connecting member 51 are separated on opposite sides of the first fixing member 60. This disperses the forces acting on the first fixing member 60, ensuring its reliability. Furthermore, the fixing of the driving member 41 to the first connecting member 51 via the first fixing member 60 facilitates assembly and disassembly of the driving member 41.

[0089] It is understandable that in other embodiments, the driving member 41 can also be directly fixed on the first connecting member 51 or the balancing body 10 by screws or other fixing elements. There is no specific limitation here, and it is only necessary to ensure that the driving member 41, the first connecting member 51 and the balancing body 10 are relatively fixed.

[0090] Further, see Figure 3-Figure 7In such an embodiment, the second connecting member 52 is provided in the first connecting member 51 and is rotationally connected to the first connecting member 51, and the transmission member 30 is fixedly connected to the second connecting member 52. When the transmission member 30 rotates, the transmission member 30 drives the second connecting member 52 to rotate relative to the first connecting member 51. In this way, the rotational connection between the transmission member 30 and the balancing body 10 is achieved through two connecting members, which can effectively reduce the friction force so that the transmission member 30 can rotate smoothly, and the second connecting member 52 can guide the rotation of the transmission member 30 and the balancing weight 20 so that they can move in a predetermined direction, that is, the circumferential direction of the chamber 13. At the same time, the first connecting member 51 and the second connecting member 52 can bear the centrifugal force of the balancing weight 20 when it rotates at high speed. Figure 5 In the illustrated embodiment, the transmission member 30 is disposed on the inner wall 131 of the second connecting member 52. It is understood that in other embodiments, the transmission member may be disposed at other locations on the second connecting member 52, which is not specifically limited herein.

[0091] Further, see Figure 3-Figure 7 In the illustrated embodiment, the guide structure 50 may further include a rolling member 53, which is arranged between the first connecting member 51 and the second connecting member 52. When the second connecting member 52 rotates relative to the first connecting member 51, the rolling member 53 rolls between the first connecting member 51 and the second connecting member 52.

[0092] In this way, the second connecting member 52 is rotatably connected to the first connecting member 51 through the rolling member 53. When the second connecting member 52 rotates, the rolling member 53 rolls accordingly between the first connecting member 51 and the second connecting member 52. The friction force generated by the rolling friction is small. In this way, when the first connecting member 51, the second connecting member 52 and the rolling member 53 bear the centrifugal force of the balancing weight 20, the small friction force can reduce the loss of the entire balancing weight 20 and the transmission member 30 during high-speed rotation and improve the ability of high-speed movement.

[0093] In one example, the guide structure 50 includes a bearing, the first connecting member 51 can be the outer ring of the bearing, and the second connecting member 52 can be the inner ring of the bearing. The rolling member 53 can be a ball or roller of the bearing, such as a tapered roller. In other words, the bearing can be a ball bearing or a tapered roller bearing. It will be understood that in such an embodiment, the use of a bearing to connect the transmission member 30 and the balancing body 10 to guide the movement of the transmission member 30 and the balancing weight 20 can improve the stability of the movement of the transmission member 30 and the balancing weight 20. At the same time, the use of a bearing to bear the centrifugal force of the balancing weight 20 reduces the inherent friction of the bearing, thereby reducing the energy consumption of the entire balancing assembly 100 and improving the ability to move at high speeds.

[0094] It is understood that in other embodiments, the guide structure 50 may omit the rolling member 53, and the first connecting member 51 and the second connecting member 52 may be smoothly connected in rotation. For example, the first connecting member 51 and the second connecting member 52 may be connected to form a circular guide rail, which is smoothly connected and can rotate relative to each other.

[0095] See also Figure 3 and Figure 4 In one example, there can be at least two guide structures 50 and at least two transmission members 30. The at least two guide structures 50 are arranged side by side along the central axis Y of the chamber 13. The at least two transmission members 30 are respectively fixedly connected to the second connecting members 52 of the at least two guide structures 50. In other words, the two transmission members 30 are also arranged side by side along the central axis Y of the chamber 13. The balancing assembly 100 may further include a second fixing member 70 fixedly connected to the first connecting members 51 of the at least two guide structures 50.

[0096] In this way, each transmission member 30, driven by the corresponding power component 40, can drive the balancing weight 20 to multiple different positions, thereby achieving the purpose of adjusting eccentricity and achieving balance using multiple balancing weights 20. Each transmission member 30 is equipped with a guide structure 50 for guidance, allowing each transmission member 30 to rotate smoothly and stably. Furthermore, connecting the first connecting member 51 of the two guide structures 50 via the second fixing member 70 not only ensures a stable connection between the two, but also allows the guide structure 50 and other components to be replaced by removing the second fixing member 70 if one of the guide structures 50 is damaged.

[0097] Specifically, in the illustrated embodiment, within a chamber 13, there are two guide structures 50, two transmission members 30, and two power components 40. The teeth 301 on each transmission member 30 mesh with the corresponding rotating member 42 of the power component 40. It is understood that in other embodiments, the number of guide structures 50, transmission members 30, and power components 40 may be more than two, or even one, and this is not a limitation.

[0098] See also Figure 4 、 Figure 8 as well as Figure 9 In some embodiments, the balancing weight 20 is arranged in parallel with the transmission member 30 along the center axis Y direction of the chamber 13.

[0099] In this way, the centrifugal force generated when the balancing weight 20 performs circular motion around the central axis Y of the chamber 13 in the chamber 13 will not directly act on the transmission member 30, so that when the first cavity 200 of the household appliance 1000 rotates at high speed, the balancing weight 20 can rotate smoothly around the central axis Y of the chamber 13.

[0100] Furthermore, in such an embodiment, the balancing block 20 is connected to one side of the transmission member 30, and the driving member 41 is arranged on the side of the transmission member 30 opposite to the balancing block 20, and the balancing block 20, the transmission member 30 and the driving member 41 are arranged in sequence along the central axis Y direction of the chamber 13.

[0101] In this way, the balancing weight 20 and the driving member 41 are respectively arranged on both sides of the transmission member 30 , which can save space in the radial direction of the balancing assembly 100 .

[0102] See also Figures 8-10 In some embodiments, the number of transmission members 30, balancing weights 20 and power members 40 can be two each. The two transmission members 30 are concentrically arranged in the chamber 13, and the two balancing weights 20 are fixedly connected to the two transmission members 30 respectively. One power member 40 is used to drive one of the transmission members 30 to rotate, and the other power member 40 is used to drive the other transmission member 30 to rotate.

[0103] In this way, the ability of the balancing assembly 100 to balance eccentricity can be improved by respectively driving the two concentric transmission members 30 to rotate through the two power components 40, thereby respectively driving the two balancing blocks 20 to move. For example, the balancing blocks 20 can be driven by the two power components 40 to move to different positions to jointly adjust the balance, and there are many adjustment methods.

[0104] Specifically, see Figures 10 to 15 The two transmission members 30 include a first transmission member 31 and a second transmission member 32. The first transmission member 31 is closer to the central axis Y of the chamber 13 than the second transmission member 32. The first transmission member 31 is formed with a first tooth portion 311 on the side away from the central axis Y of the chamber 13, and the second transmission member 32 is formed with a second tooth portion 321 on the side facing the central axis Y of the chamber 13. The two power components 40 include a first gear 421 and a second gear 422. The first gear 421 and the second gear 422 are both located between the first transmission member 31 and the second transmission member 32. The first gear 421 is engaged with the first tooth portion 311, and the second gear 422 is engaged with the second tooth portion 321.

[0105] In this way, the two power components 40 can respectively drive the first transmission member 31 and the second transmission member 32 to rotate via the first gear 421 and the second gear 422, thereby driving the two balancing weights 20 to rotate within the chamber 13 about the central axis Y of the chamber 13 to adjust the balance. Furthermore, the first gear 421 and the second gear 422 are both located between the first transmission member 31 and the second transmission member 32, which effectively reduces the radial space occupied by the power components 40 on the balancing body 10, thereby making the balancing assembly 100 more compact and smaller in size, thereby saving costs.

[0106] Also, see Figures 10 to 15In the illustrated embodiment, the two balancing weights 20 are located on the same circumference with the central axis X of the chamber 13 as the center line.

[0107] In this way, the two balancing weights 20 move on the same circumference, which can reduce the space of the balancing assembly 100 in the radial direction.

[0108] See also Figure 13 In some embodiments, the balancing assembly 100 further includes a connecting plate 80, which is fixedly connected to one side of the transmission member 30, and the balancing block 20 is mounted on the connecting plate 80, and the balancing block 20 can move relative to the connecting plate 80 along the radial direction of the chamber 13.

[0109] In this way, when the transmission member 30 drives the balancing weight 20 to move, the balancing weight 20 can move a certain buffer distance relative to the connecting plate 80 under the action of centrifugal force, thereby buffering the centrifugal force to prevent the centrifugal force from directly acting on the transmission member 30 and affecting the stability of the movement.

[0110] Further, see Figure 13 、 Figure 16 as well as Figure 17 In such an embodiment, the connecting plate 80 may be formed with a mounting hole 81, and the balancing block 20 may be formed with a mounting post 23, the mounting post 23 cooperates with the mounting hole 81, and the mounting post 23 can move in the mounting hole 81 so that the balancing block 20 can move relative to the connecting plate 80 along the radial direction of the chamber 13.

[0111] In this way, by cooperating with the mounting column 23 and the mounting hole 81, on the one hand, the connecting plate 80 can drive the balance block 20 to move along with the transmission member 30 through the cooperation of the two. On the other hand, the mounting column 23 can move radially along the chamber 13 in the mounting hole 81 to buffer the centrifugal force, prevent the centrifugal force from directly acting on the transmission member 30 or reduce the centrifugal force acting on the transmission member 30. At the same time, the cooperation between the two is relatively simple and convenient for disassembly and assembly.

[0112] Specifically, see Figure 13 In this embodiment, the mounting hole 81 can be a waist-shaped hole, which is opened in the radial direction of the chamber 13. In this way, on the one hand, the connecting plate 80 can drive the balance weight 20 to move through the waist-shaped hole, and on the other hand, the balance weight 20 can also move along the waist-shaped hole under the action of centrifugal force. It is understood that in other embodiments, the mounting hole 81 can also have other shapes, such as an elliptical hole.

[0113] It can be fixedly mounted on the transmission member 30 via the connecting plate 80. For example, see Figure 13 and Figure 15In the illustrated embodiment, the two balancing weights 20 are fixedly mounted on the first transmission member 31 and the second transmission member 32 respectively via the connecting plates 80. Of course, in other embodiments, the balancing weights 20 and the transmission member 30 may also be directly fixedly connected together, for example, by welding or directly fixing them together with screws.

[0114] Further, see Figure 8 In this embodiment, one of the two transmission members 30 is rotatably connected to the first ring body 11, and the other of the two transmission members 30 is rotatably connected to the second ring body 12. In other words, one of the first transmission member 31 and the second transmission member 31 is rotatably connected to the first ring body 11, and the other is rotatably connected to the second ring body 12.

[0115] Specifically, in Figure 8 In the illustrated embodiment, the first transmission member 31 is rotationally connected to the second ring body 12, and the second transmission member 32 is rotationally connected to the first ring body 11. The second ring body 12 includes a plate portion 121 and a protruding ring portion 122 protruding from the plate portion 121. The first and second ring bodies 11 and 12 cooperate to form the balancing body 10. The plate portion 121, the protruding ring portion 122 of the second ring body 12, and the inner wall of the first ring body 11 together form a closed annular chamber 13. The outer peripheral wall of the protruding ring portion 122 and the inner wall of the first ring body 131 serve as the two inner walls of the chamber 13 along the radial direction of the chamber 13.

[0116] In such an embodiment, the first transmission member 31 and the second ring body 12 can be rotationally connected by forming an annular groove on the outer peripheral wall of the convex ring portion 122 of the second ring body 12, and the first transmission member 31 is disposed in the annular groove and can rotate therein. It is understood that in such an embodiment, the rotational connection method of the second transmission member 32 and the first ring body 11 can be the same as or different from the rotational connection method of the first transmission member 31 and the second ring body 12. For example, an annular groove can be formed on the inner wall of the first ring body 11, and the second transmission member 32 can be disposed in the annular groove and can rotate therein.

[0117] Furthermore, it is understood that, in order to reduce friction during relative rotation between the first transmission member 31 and the second ring body 12, and to reduce friction between the second transmission member 32 and the first ring body 11, in some embodiments, a ball bearing may be provided between the first transmission member 31 and the second ring body 12. When the first transmission member 31 rotates relative to the second ring body 12, the ball bearing rotates therebetween, achieving rolling friction between the first transmission member 31 and the second ring body 12 via the ball bearing. A ball bearing may also be provided between the second transmission member 32 and the first ring body 11. When the second transmission member 32 rotates relative to the first ring body 11, the ball bearing rotates therebetween, achieving rolling friction between the second transmission member 32 and the first ring body 12 via the ball bearing.

[0118] Of course, in some embodiments, the first transmission member 31 and the second ring body 12 are rotatably connected, and the second transmission member 32 and the first ring body 11 are rotatably connected by the guide structure 50 (e.g., the bearing) in the above embodiment to achieve the rotatable connection between the first transmission member 31 and the second ring body 12, and the second transmission member 32 and the second ring body 12. In this way, the use of the guide structure 50 can effectively reduce the friction between the two, thereby reducing energy loss and enabling the first transmission member 31 to rotate smoothly and at high speed. The specific structure of the guide structure 50 can be understood with reference to the above, and will not be repeated here.

[0119] That is to say, in Figures 8-10 In the illustrated embodiment, the first transmission member 31 and the second ring body 12 of the balancing body 10 can be rotationally connected via the aforementioned guide structure 50, and the second transmission member 32 and the first ring body 11 of the balancing body 10 can also be rotationally connected via the aforementioned guide structure 50, without specific limitation herein.

[0120] See also Figure 16 In some embodiments, the balancing weight 20 may include a body 21 and a support structure 22. The body 21 is fixedly connected to the transmission member 30. The support structure 22 is provided on the body 21 and supported on the inner wall 131 of the chamber 13. In this way, the contact between the support structure 22 and the inner wall 131 reduces the shaking of the balancing weight 20 when it moves in the chamber 13.

[0121] Specifically, the balancing weight 20 is supported on the inner wall 131 of the chamber 13 by the support structure 22. When the balancing weight 20 moves in the chamber 13, the inner wall 131 of the chamber 13 can withstand the centrifugal force of the balancing weight 20, thereby preventing the balancing weight 20 from shaking during movement.

[0122] Please combine Figure 17 The balancing weight 20 can be in contact with the inner wall 131 of the chamber 13 in a rolling manner. Specifically, the support structure 22 may include a roller 221, which is rotatably mounted on the body 21 and contacts the inner wall 131 of the chamber 13. When the balancing weight 20 moves, the roller 221 can rotate relative to the body 21. It can be understood that the roller 221 plays the role of supporting the entire balancing weight 20.

[0123] Specifically, the roller 221 can be connected to the body 22 via a fixed shaft 222. The fixed shaft 222 is fixedly connected to the body 21. The fixed connection method can be metal welding, screw connection, snap-on connection, or interference fit, which is not specifically limited here. The roller 221 is passed through the fixed shaft 222, and the roller 221 is sleeved on the fixed shaft 222. The body 21 includes a first side 211 and a second side 212 that are opposite to each other. The rollers 221 are provided at both ends of the first side 211 and on both sides of the second side 212. When the driving member 41 drives the transmission member 30 to move the balancing weight 20, the rollers 221 rotate about the fixed shaft 222 and rotate relative to the body 21, allowing the balancing weight 20 to move smoothly within the chamber 13. Furthermore, it will be understood that the balancing weight 20 is sealed within the chamber 13 of the balancing body 10. When the balancing weight 20 moves, it rubs against the inner wall 131 of the chamber 13. The roller 221 provided on the body 21 can effectively reduce friction between the balancing weight 20 and the inner wall 131 of the chamber 13. It is understood that in other embodiments, the balancing weight 20 and the inner wall 131 of the chamber 13 may also be in sliding contact. In this case, lubricating oil may be added to the balancing weight 20 and the inner wall 131 of the chamber 13 to further reduce friction. This is not specifically limited herein; the contact method between the balancing weight 20 and the inner wall 131 of the chamber 13 can be such that friction between the balancing weight 20 and the inner wall 131 of the chamber 13 is reduced.

[0124] Furthermore, in some embodiments, the roller 221 may include a bearing 2211 and a vibration damper 2212. The bearing 2211 is rotatably mounted on the body 21. Specifically, the bearing 2211 is mounted on the fixed shaft 222, and the vibration damper 2212 is mounted on the bearing 2211. The bearing 2211 is supported on the inner wall 131 of the chamber 13 via the vibration damper 2212. In this way, when the balancing weight 20 moves, the vibration damper 2212 can reduce vibration generated between the roller 221 and the inner wall 131 of the chamber 13. Specifically, the vibration damper 2212 is elastic. In one example, the vibration damper 2212 can be a rubber ring. When the balancing weight 20 is subjected to centrifugal force, the vibration damper 2212 can deform to contact the inner wall 131 of the chamber 13, thereby reducing vibration between the roller 221 and the inner wall 131 of the chamber 13. In another example, the vibration damper 2212 can also be an elastic element such as a silicone ring. It is understood that in some embodiments, the vibration damper 2212 can be omitted from the roller 221, and the bearing 2211 can be directly supported on the inner wall 131 of the chamber 13. It is understood that in other embodiments, the roller 221 can also adopt other structures, not limited to the bearing 2211.

[0125] Also, see Figure 13 and Figure 17In the illustrated embodiment, there are three mounting holes 18 and three mounting posts 23, one of which is directly formed on or mounted on the body 21. The other two mounting posts 23 are directly formed on one end of the fixed shaft 222. In this way, the mounting posts 23 can be directly formed by the fixed shaft 222 without the need for additional mounting posts 23.

[0126] In addition, by Figure 3-Figure 6 It can be seen that in Figure 3-Figure 6 In the embodiment shown, the balancing mass 20 is a plate-shaped mass. It is understood that in some embodiments, Figure 3-Figure 6 The balancing weight 20 in the embodiment shown may also be Figure 11-16 The structure of the balance weight 20 shown in FIG is not specifically limited here. The material of the balance weight 10 can be metal or non-metal, and non-metal can include plastic, ceramic, etc. It is not specifically limited here.

[0127] In summary, a balancing assembly 100 according to an embodiment of the present application is used in a household appliance 1000. The balancing assembly 100 includes a balancing body 10, a balancing weight 20, a transmission member 30, and a power component 40. An annular chamber 13 is provided in the balancing body 10. The transmission member 30 is disposed in the chamber 13 and is capable of rotating around the central axis Y of the chamber 13. The balancing weight 20 is located in the chamber 13 and is fixedly connected to the transmission member 30. The power component 40 is fixedly connected to the balancing body 10. The power component 40 is configured to drive the transmission member 30 to rotate in the chamber 13, thereby driving the balancing weight 20 to rotate around the central axis Y of the chamber 13 in the chamber 13.

[0128] The present invention provides a household appliance 1000, comprising a first cavity 200, a second cavity 300, and the balancing assembly 100 of the above embodiment. The first cavity 200 is rotatably connected to the second cavity 300, and the balancing body 10 of the balancing assembly 100 is installed in the first cavity 200.

[0129] In the balancing assembly 100 and household appliance 1000 of the above-described embodiment, the transmission member 30 is fixedly connected to the balancing weight 20, and the power component 40 is fixed to the balancing body 10 and can drive the transmission member 30 to rotate, thereby driving the balancing weight 20 to rotate within the chamber 13. As such, the power component 40 is fixed relative to the balancing body 10 and does not move with the balancing weight 20. When the power component 40 drives the transmission member 30 to rotate, thereby driving the balancing weight 20 to rotate, it is not affected by centrifugal force. This allows the power component 40 and the transmission member 30 to smoothly drive the transmission member 30 to rotate, thereby driving the balancing weight 20 to rotate, even during high-speed rotation of the chamber of the household appliance 1000.
