Referring to fig. 1 to 5, a balance assembly 100 according to an embodiment of the present invention is applied to a household appliance 1000. The home appliance 1000 includes a balancing assembly 100, a first cavity 200 and a second cavity 300. The first chamber 200 is rotatably connected to the second chamber 300, and a load can be placed in the first chamber 200. The balancing assembly 100 includes a balancing body 10 and a balancer 20. The balance body 10 is installed in the first chamber 200. An annular chamber 13 is provided in the balance body 10, and a balancer 20 is provided in the chamber 13. The balancer 20 is movable within the chamber 13. The home appliance 1000 may be a laundry treating appliance such as a washing machine, a dryer, or other home appliances 1000 having the first cavity 200 capable of rotating. The load can be clothes, quilts and other objects needing to be cleaned.

It can be understood that when the household appliance 1000 is in operation, the first cavity 200 can rotate relative to the second cavity 300, and the load in the first cavity 200 is easily distributed unevenly, and is eccentric. In case that the first chamber 200 is rotated and the load is eccentric, the home appliance 1000 may generate a large vibration. The balance body 10 is fixedly connected to the first chamber 200 and rotates together with the first chamber 200. Therefore, it is possible to offset or reduce the eccentric mass when the first chamber 200 rotates by means of the self-gravity and the centripetal force of the balancer 20 by controlling the movement of the balancer 20 within the balancing body 10, and thus it is possible to reduce the vibration of the home appliance 1000.

In the illustrated embodiment, the first chamber 200 is rotatably provided in the second chamber 300. It is understood that in other embodiments, the first cavity 200 and the second cavity 300 may be connected in other manners, and are not limited in particular. In the present embodiment, the household appliance 1000 is a washing machine, which can be used to wash clothes, and the clothes are placed in the first cavity 200. The first chamber 200 is a washing chamber (inner tub), the second chamber 300 is a water chamber (outer tub), the water chamber and the washing chamber are cylindrical, the washing chamber is rotatably disposed in the water chamber, and the water chamber and the washing chamber are disposed in a housing (not shown) of the household appliance 1000. The washing chamber may have a rotation axis X arranged horizontally, obliquely or vertically. That is, the axis of rotation X of the washing chamber is parallel, inclined or perpendicular to the horizontal plane. It will be appreciated that one or more balance bodies 10 may be provided at any position of the washing chamber, and the balance bodies 10 rotate with the rotation of the washing chamber. The central axis Y of the chamber 13 is parallel to or coincides with the rotation axis X of the washing chamber, i.e. the balancing body 10 may be arranged coaxially with the washing chamber or eccentrically with respect to the washing chamber. The balance 10 may also be spirally arranged on the washing chamber.

In addition, referring to fig. 1, in order to further reduce the transmission of the vibration inside the washing machine to the outside, the water containing cavity may be connected to the mounting plate 400 through a vibration damping structure, and the mounting plate 400 may be fixed to the bottom plate of the housing or may be the bottom plate of the housing. The vibration damping structure can adopt structural components such as springs, hydraulic pressure and the like to reduce the transmission of vibration.

Referring to fig. 1-3, the household appliance 1000 is a drum washing machine. The first cavity 200 comprises a first end 201 and a second end 202 along the axis of rotation X. The first end 201 and the second end 202 are respectively mounted with the balance body 10. At least one balancer 20, for example, one or two or more than two, is provided in the chamber 13 of each balancing body 10. Preferably, two balancers 20 are provided in the chamber 13 of the balancing body 10, and the initial balancing positions of the two balancers 20 are symmetrically arranged along the radial direction of the balancing body 10, in such a manner that the first chamber 200 can be balanced in an unloaded state.

Specifically, the second end 202 of the first cavity 200 may be connected to a rotating shaft 600 (see fig. 17), the rotating shaft 600 is rotatably connected to the fixing frame 500, and a power device (not shown) of the household appliance 1000 may be connected to the rotating shaft 600 to drive the first cavity 200 to rotate. In the embodiment shown in fig. 3, the first end 201 of the first cavity 200 is a front end, and the second end 202 is a rear end, and the front end may refer to an end facing a user. In other embodiments, the first end 201 or the second end 202 of the first cavity 200 is provided with the balance body 10, or the balance body 10 is provided between the first end 201 and the second end 202. The mount 500 may be a tripod.

In the embodiment shown in fig. 3, the balance body 10 has a ring shape, and the balance body 10 may be referred to as a balance ring. It is understood that in other embodiments, the balancing body 10 may have other shapes, such as a plate shape, a square ring shape, an elliptical ring shape, etc., and is not particularly limited thereto.

Referring to fig. 4, each of the balancers 10 includes a first ring body 11 and a second ring body 12, the first ring body 11 and the second ring body 12 together form a sealed chamber 13, and two balancers 20 are disposed in the chamber 13. Since the balance body 10 has a circular ring shape, the balancer 20 can move circularly in the chamber 13 of the balance body 10. In the embodiment shown in fig. 3, the first ring member 11 defines a chamber 13, which may be referred to as a balance ring body 22, and the second ring member 12 may be referred to as an end cap, wherein the second ring member 12 is connected to the first ring member 11 to seal the chamber 13.

Referring to fig. 4, the inner wall 131 of the chamber 13 includes a first sidewall 1311, a second sidewall 1312, a first connecting wall 1313 and a second connecting wall 1314. The first sidewall 1311 and the second sidewall 1312 are sequentially spaced apart in a radial direction of the chamber 13, and the first sidewall 1311 is closer to the central axis Y of the chamber 13 than the second sidewall 1312. The first connection wall 1313 connects the first and second side walls 1311 and 1312, the second connection wall 1314 connects the first and second side walls 1311 and 1312, and the second connection wall 1314 and the first connection wall 1313 are oppositely disposed. Specifically, the first ring body 11 includes a first side wall 1311, a second side wall 1312, and a first connection wall 1313, and the second ring body 12 includes a second connection wall 1314. In the illustrated embodiment, the central axis Y of the chamber 13 coincides with the rotation axis X of the first cavity 200.

Referring to fig. 6 to 9, the balancer 20 includes a power member 21, a body 22, a support structure 23, a brush wire structure 24, and a balance control plate 25. The power part 21 is connected with the balance control board 25, the balance control board 25 is provided with a balance controller 251 to control the operation of the balancer 20, for example, the balance controller 251 controls the power part 21 to drive the balancer 20 to move in the cavity 13 of the balance body 10; as another example, the control balancer 20 communicates with the home appliance 1000, and the like.

Specifically, the power unit 21 includes a driver 211 and a coupling gear 2121, and the driver 211 is connected to the coupling gear 2121. Referring to fig. 5 and 11, the balance assembly 100 further includes a ring-shaped tooth portion 30, the tooth portion 30 is disposed in the chamber 13 along the circumference of the balance body 10, specifically, the tooth portion 30 is disposed on the first sidewall 1311, and the combination gear 2121 is engaged with the tooth portion 30.

It can be understood that the balancer 20 is driven by the engagement of the coupling gear 2121 with the tooth portion 30, the engagement has the characteristics of high precision and stable transmission, and there is no slip risk, and the coupling gear 2121 is engaged with the tooth portion 30 provided on the first side wall 1311 near the central axis Y of the balance body 10, so that it is possible to prevent the balancer 20 from being driven difficultly due to resistance caused by too tight engagement due to centrifugal force generated when the first chamber 200 rotates, thereby ensuring smooth and stable movement of the balancer 20 in the chamber 13 when the first chamber 200 rotates, particularly, at high speed.

In the illustrated embodiment, the number of the coupling gears 2121, with which each balancer 20 meshes with the tooth 30, is single. In this way, one annular tooth 30 may be provided on the first side wall 1311, and the combination gear 2121 and the tooth 30 are single, which can save cost. In other embodiments, the number of the combination gears 2121 may be two or other numbers, and the number of the teeth 30 may be set according to actual needs. Two or more combining gears 2121 may be engaged with one tooth portion 30.

It is understood that in other embodiments, the tooth 30 may be disposed on the second sidewall 1312 of the chamber 13, and is not limited herein.

Referring to fig. 6, the main body 22 is formed with an opening 221, the power member 21 is formed in the main body 22, and the coupling gear 2121 is partially exposed from the opening 221. In this way, the portion of the coupling gear 2121 exposed from the opening 221 is engaged with the tooth portion 30 provided on the first side wall 1311, and the power member 21 can move the balancer 20 by the engagement action of the driving coupling gear 2121 with the tooth portion 30. It should be noted that the body 22 may be integrally formed by using a steel plate with a relatively high rigidity, so that the balancer 20 may be reliably and stably maintained when the first chamber 200 rotates at a high speed. It is understood that the body 22 may be made of other metal or non-metal materials, and is not limited thereto.

Further, in some embodiments, the power component 21 further comprises a speed regulation structure 212, the speed regulation structure 212 comprising a combination gear 2121, the speed regulation structure 212 being connected to the drive member 211. In this way, the speed adjusting structure 212 can adjust the output torque of the driving member 211, thereby adjusting and controlling the moving speed of the balancer 20. Specifically, referring to fig. 10, the speed adjustment structure 212 includes a first stage transmission structure 2122 and a second stage transmission structure 2123, the first stage transmission structure 2122 is connected to the output shaft 2111 of the driving member 211, and the second stage transmission structure 2123 is connected to the first stage transmission structure 2122 and the combining gear 2121. In this manner, the reduction ratio of the balancer 20 can be realized by the two-stage transmission structure.

Referring to fig. 9 and 10, the governor structure 212 can include a housing 2124 and a first stage transmission 2122 and a second stage transmission 2123 located within the housing 2124. The case 2124 may be made of a firm, non-deformable thick steel plate, and the entire case 2124 is rectangular. In other embodiments, the housing 2124 may have other shapes such as a cube, a prism, or a cylinder. The conjoined gear 2121 is connected to the second stage transmission structure 2123 and partially exposed from the housing 2124.

Specifically, in an embodiment of the present invention, the first stage transmission structure 2122 includes a worm 21221 and a worm wheel 21222. The second stage gearing arrangement 2123 includes a first gear 21231 and a second gear 21232. The worm 21221 connects the output shaft 2111 of the driving member 211 with the worm wheel 21222, the worm wheel 21222 is fixedly connected with the first gear 21231, the first gear 21231 is engaged with the second gear 21232, and the second gear 21232 is connected with the combination gear 2121. In the embodiment shown in fig. 10, the second gear 21232 is a duplicate gear that meshes with the first gear 21231 and the coupling gear 2121, respectively. In other embodiments, the second gear 21232 can be a single gear, selected according to a reduction ratio or other parameters, and is not particularly limited herein.

In the process of operating the power component 21, firstly the driving component 211 drives the worm 21221 to rotate through the output shaft 2111, then the worm 21221 drives the worm wheel 21222 matched with the worm to rotate, so as to realize the first-stage transmission, and further the worm wheel 21222 drives the first gear 21231, and then the first gear 21231 drives the second gear 21232, so as to realize the second-stage transmission. The second gear 21232 rotates the coupling gear 2121, thereby moving the balancer 20 in the chamber 13. Since the worm wheel 21222 and the worm 21221 have self-locking performance, the worm wheel 21222 and the worm 21221 can also function as a limit, and the balancer 20 can be stably stopped at a certain position in the chamber 13 under the condition that the driving member 211 does not work.

Referring to fig. 9, the driving member 211 further includes a displacement detecting member 80. In the case where the power unit 21 drives the balancer 20 to move within the chamber 13, the displacement detecting member 80 is used to detect the number of rotations of the output shaft 2111, the number of rotations of the output shaft 2111 being correlated with the position of the balancer 20.

It will be appreciated that the drive member 211 may be a motor, with the output shaft 2111 being a motor shaft. In the case where the power element 21 drives the balancer 20 to move within the chamber 13, the number of rotations of the output shaft 2111 is correlated with the position of the balancer 20. Therefore, the moving distance of the balancer 20 can be determined by detecting the number of rotations of the output shaft 2111, and the position of the balancer 20 can be determined in conjunction with the initial balancing position of the balancer 20. The initial equilibrium position may refer to a position before the balancer 20 starts moving within the chamber 13 or a position that can be determined during movement of the balancer 20.

Specifically, the displacement detecting member 80 includes a hall sensor and a magnetic member. The hall sensor is arranged on the output shaft 2111 of the driving piece 211 and rotates along with the rotation of the output shaft 2111, and the magnetic piece is fixedly arranged at other positions of the driving piece 211 or the balancer 20 and is kept still. When the hall sensor is rotated to a position opposite to the magnetic member, the hall sensor outputs a pulse signal under the influence of the magnetic field generated by the magnetic member, so that the number of rotations of the output shaft 2111 can be detected. The magnetic member may be a permanent magnet. It is understood that the hall sensor may be fixed, and the magnetic member is disposed on the output shaft 2111 of the driving member 211 and rotates with the rotation of the output shaft 2111.

In other embodiments, the displacement detecting member 80 may be an optical sensor, an ultrasonic sensor, or the like. In one example, the optical sensor includes a light emitting element and a light receiving element, one of which is fixed to the output shaft 2111 to rotate with the rotation of the output shaft 2111, and the other of which is fixed to the driving element 211 or other position of the balancer 20 to be kept stationary. One rotation of the output shaft 2111 allows the light receiving element to receive the light signal emitted from the emitting element, so that the number of rotations of the output shaft 2111 can be detected. The detection principle of the ultrasonic sensor is similar to that of the optical sensor, and is not described in detail herein.

In other embodiments, in the case where the displacement detecting member 80 is an optical sensor, the optical sensor includes a light emitting element and a light receiving element, and the output shaft 2111 of the driving member 211 is provided with a member having a reflectance different from that of the output shaft 2111, for example, a dark color coating layer is formed on the output shaft 2111 of the driving member 211. The light emitting element and the light receiving element are arranged obliquely below the output shaft 2111 and are symmetrically arranged along the output shaft 2111, light emitted by the light emitting element is incident on the output shaft 2111 or the component, the light receiving element receives the light reflected by the output shaft 2111 or the component, and because the reflectivity of the output shaft 2111 is different from that of the component, the light receiving element correspondingly receives light signal intensity with difference conductance, so that in the rotating process of the output shaft 2111, the displacement detection element 80 detects a plurality of pulses, one pulse can correspond to one circle of rotation of the output shaft 2111, two pulses can correspond to one circle of rotation of the output shaft 2111, more than two pulses can correspond to one circle of rotation of the output shaft 2111, and the like, and specific calibration can be carried out according to actual conditions.

Referring to fig. 5 and 6, the support structure 23 is disposed on the body 22, and the support structure 23 is supported on the inner wall 131 of the chamber 13. In this manner, the operation of the balancer 20 is more stabilized by the contact of the support structure 23 with the inner wall 131.

Specifically, the supporting structure 23 includes a roller 231, the roller 231 is rotatably disposed on the body 22, and the roller 231 contacts the second sidewall 1312. In the case where the balancer 20 moves, the roller 231 can rotate relative to the body 22. It can be understood that the roller 231 plays a role of bearing the centrifugal force and the gravity of the entire balancer 20. Referring to fig. 7, the roller 231 may be a bearing and is connected to the body 22 through a fixing shaft 2311. The fixing shaft 2311 is fixedly connected with the body 22 by welding, screwing, snapping, interference, and the like, which is not limited in detail herein. The roller 231 is sleeved on the fixing shaft 2311, and the roller 231 can rotate relative to the body 22. The rollers 231 are disposed at both ends of the body 22 along the circumferential direction of the chamber 13, and when the driving member 211 drives the combining gear 2121 to drive the balancer 20 to move, the rollers 231 rotate around the fixing shaft 2311 and rotate relative to the body 22, so that the balancer 20 moves more stably in the chamber 13. In other embodiments, the roller 231 may include a shaft and a wheel, the wheel is fixedly connected to the shaft, and the shaft is rotatably connected to the body 22. The number of wheels may be one, or two or more than two.

It is understood that in other embodiments, the support structure 23 may also include rollers (not shown) disposed between the body 22 and the second sidewall 1312 that roll between the body 22 and the second sidewall 1312 upon movement of the balancer 20. In this manner, the arrangement of the rolling members can reduce the friction between the balancer 20 and the second side wall 1312 to ensure that the balancer 20 can move smoothly in the chamber 13, and at the same time, the arrangement of the rolling members can play a role in bearing the centrifugal force of the entire balancer 20. In particular, in such embodiments, the rolling members may be balls.

Further, the support structure 23 includes an anti-friction member 232, the anti-friction member 232 is rotatably disposed on the body 22, and the anti-friction member 232 contacts the first connecting wall 1313 and/or the second connecting wall 1314. In the case where the balancer 20 moves, the anti-friction member 232 can rotate relative to the body 22. Thus, the movement space of the balancer 20 is further defined, the deviation of the balancer 20 in other directions is reduced, and the resistance to the movement of the balancer 20 is reduced, thereby improving the stability of the movement of the balancer 20. It is understood that the balancer 20 is located in the sealed chamber 13, a desired moving direction of the balancer 20 is in a circumferential direction of the chamber 13 when the balancer 20 moves, and the balancer 20 may rub against the first connection wall 1313 and/or the second connection wall 1314 during the movement. The anti-friction member 232, which is provided on the body 22 and contacts the first connecting wall 1313 and/or the second connecting wall 1314, can correct and limit the moving direction of the balancer 20, and can effectively reduce the friction force when the balancer 20 contacts the first connecting wall 1313 and/or the second connecting wall 1314.

In one embodiment, the anti-friction members 232 may be rotatably provided at both sides of the body 22, and the anti-friction members 232 located at both sides of the body 22 contact the first connecting wall 1313 and the second connecting wall 1314. In another embodiment, the anti-friction member 232 may be rotatably disposed at one side of the body 22, and the anti-friction member 232 at one side of the body 22 contacts the first connecting wall 1313 or the second connecting wall 1314.

In one example, the anti-friction member 232 includes bull's-eye wheels, and three bull's-eye wheels are provided at intervals on both sides of the body 22 contacting the first and second connecting walls 1313 and 1314. In other embodiments, the side contacting the first connecting wall 1313 may be provided with a bull's-eye wheel, or the side contacting the second connecting portion may be provided with a bull's-eye wheel. The number of the bull's-eye wheels arranged on each side face can be one, two or other number, and is not limited in particular. Of course, the anti-friction member 232 may be other members having an anti-friction function.

Note that, a balance control plate 25 is provided at one of the end portions of the body 22. The balancer 20 further includes a bumper 26, and the bumper 26 is provided at an end of the body 22. The bumper 26 protrudes relative to the balance control plate 25. The bumper 26 can protect the balance control panel 25 from being hit by other objects. In the illustrated embodiment, the bumper 26 may be a bumper beam.

Referring to fig. 5, 6 and 11-15, the inner wall 131 of the chamber 13 is provided with a rail structure 40, and the rail structure 40 includes a rail 41. The balancer 20 includes a filament arrangement 24, and the filament arrangement 24 includes filaments 241. The brush filaments 241 are electrically connected to the guide rail 41 so as to be relatively slidable. In this way, the balancer 20 in the balancing body 10 can be supplied with power and/or communicate with the rail 41 and the brush wires 241, and the balancer 20 is supplied with power by the brush wires, which requires fewer parts, has excellent conductivity by virtue of the electrical connection of the brush wires 241 with the rail 41, and can ensure the reliability of power supply and/or communication. Preferably, the brush filaments 241 are elastically and electrically connected with the guide rail 41, so that the reliability of power supply and/or communication can be further ensured.

In one embodiment, the brush filaments 241 have elasticity, and can stably adhere to the guide rail 41 by virtue of the pre-tightening force of the brush filaments 241, so that the brush filaments 241 are stably and electrically connected with the guide rail 41 without additional components for providing the pre-tightening force. The brush wire 241 may be made of copper-silver alloy with better conductivity, and the guide rail 41 may be made of copper guide rail 41. In another embodiment, the elastic guide rail 41 may be used to electrically connect the brush filaments 241, so as to ensure the reliability of the electrical connection between the brush filaments 241 and the guide rail 41.

Specifically, in such an embodiment, the guide rail 41 is formed with an annular rail, the brush filaments 241 elastically abut against the annular rail, and when the balancer 20 moves in the chamber 13, the brush filaments 241 move in the annular rail and maintain a state of abutting against the annular rail. Thus, the brush wires 241 can be kept in contact with the guide rails 41 regardless of the movement of the balancer 20 in the chamber 13 due to the elastic force of the brush wires 241, thereby ensuring the reliability of power supply and communication.

Referring to fig. 13, in some embodiments, the track 41 includes a first conductive track 411 and a second conductive track 412, the brush filament 241 includes a first conductive brush filament 2411 and a second conductive brush filament 2412, the first conductive brush filament 2411 is slidably connected to the first conductive track 411, and the second conductive brush filament 2412 is slidably connected to the second conductive track 412. In this manner, the balancer 20 may take electric power from the conductive rail through the conductive brush wires by electrically connecting the conductive brush wires and the conductive rail, and transmit the electric power to electric components of the balancer 20, for example, the balance control board 25 and the driving member 211, thereby enabling the balancer 20 to normally operate.

In the embodiment shown in fig. 13, the track structure 40 further includes a first track base 42, the first conductive track 411 and the second conductive track 412 are spaced apart from each other on the first track base 42, and the first track base 42 is disposed on the inner wall 131 of the chamber 13, for example, the first side wall 1311. The filament arrangement 24 includes a filament mount 242, and first and second electrically conductive filaments 2411 and 2412 are disposed on the filament mount 242. In other embodiments, the rail structure 40 may omit the first rail housing 42, and the first conductive rail 411 and the second conductive rail 412 may be directly disposed on the inner wall 131 of the chamber 13, for example, the first sidewall 1311. The filament arrangement 24 may omit the filament mount 242, and the first conductive filaments 2411 and the second conductive filaments 2412 may be directly provided on the body 22 of the balancer 20.

Further, referring to fig. 13, in some embodiments, the track 41 includes a first communication track 413 and a second communication track 414, the brush filaments 241 include a first communication brush filament 2413 and a second communication brush filament 2414, the first communication brush filament 2413 is slidably coupled to the first communication track 413, and the second communication brush filament 2414 is slidably coupled to the second communication track 414. In this manner, the balancer 20 can communicate with the controller 60 through the communication brush and the communication rail by electrically connecting the communication rail and the communication brush, for example, the balancer 20 acquires a movement instruction from the controller 60, the balancer 20 feeds back its current position information to the controller 60, and the like.

In the embodiment shown in fig. 13, the rail structure 40 comprises a second rail seat 43, the first communication rail 413 and the second communication rail 414 are arranged at a distance from the second rail seat 43, and the second rail seat 43 is arranged on the inner wall 131 of the chamber 13, for example, on the first side wall 1311. The filament arrangement 24 includes a filament mount 242, and first and second communication filaments 2413 and 2414 are disposed on the filament mount 242. In other embodiments, the rail structure 40 may omit the second rail mount 43, and the first communication rail 413 and the second communication rail 414 may be disposed directly on the inner wall 131 of the chamber 13, such as the first sidewall 1311. The brush wire structure 24 may omit the brush wire holder 242, and the first and second communication brush wires 2413 and 2414 may be directly provided at the body 22 of the balancer 20.

Referring to fig. 15, the first conductive brush filaments 2411, the second conductive brush filaments 2412, the first communication brush filaments 2413, and the second communication brush filaments 2414 are disposed on two sides of the brush filament base 242. Thus, the reliability of power transmission and communication can be further improved. Under the condition that the conductive brush wires and/or the communication brush wires on one side have faults, the conductive brush wires on the other side can still realize power transmission, and the communication brush wires can still realize communication. In other embodiments, it is understood that the first conductive brush filaments 2411, the second conductive brush filaments 2412, the first communication brush filaments 2413 and the second communication brush filaments 2414 can be disposed on one side of the brush filament holder 242 to save cost.

It is understood that, in the embodiment of the present invention, each of the conductive guide rail and the communication guide rail is formed with an annular rail, that is, the first conductive guide rail 411, the second conductive guide rail 412, the first communication guide rail 413 and the second communication guide rail 414 are formed with an annular rail, so that the first conductive brush filaments 2411, the second conductive brush filaments 2412, the first communication brush filaments 2413 and the second communication brush filaments 2414 can elastically abut against the corresponding annular rails.

Referring to fig. 5 and 15, in the embodiment of the present invention, the brush filament 241 is elongated, the brush filament 241 is connected to the brush filament seat 242, the brush filament 241 is disposed opposite to the guide rail 41, and the middle portion of the brush filament 241 is bent toward the side of the guide rail 41, so that the brush filament 241 elastically abuts against the circular track of the guide rail 41.

In this way, the bent portions of the brush wires 241 are abutted against the guide rail 41, which makes it possible to make the connection of the brush wires 241 with the guide rail 241 reliable.

Specifically, in such an embodiment, the brush filaments 241 are in a normal state before the balancer 20 is mounted, and during the mounting process, the body 22 of the balancer 20 may be first mounted in the cavity 13, and then the brush filaments 241 are bent to cause a certain amount of elastic deformation of the brush filaments 241 so as to place the brush filaments 241 in the cavity 13 to abut against the annular rail of the guide rail 31.

Referring to fig. 11, in the illustrated embodiment, the first conductive track 411, the second conductive track 412, the first communication track 413 and the second communication track 414 are all disposed along the circumferential direction of the inner wall 131 of the chamber 13, the first conductive track 411 and the second conductive track 412 are located on one side of the tooth portion 30, and the first communication track 413 and the second communication track 414 are located on the other side of the tooth portion 30. That is, the tooth portion 30 is provided between the conductive rail and the communication rail at an intermediate position of the housing 13, so that the engaging gear 2121 is also located at an intermediate position of the housing 13. In this way, the engagement of the coupling gear 2121 with the teeth 30 and the support structure 23 can effectively support the balancer 20 to prevent the balancer 20 from shaking.

In the above embodiment, the guide rail 41 is provided on the first sidewall 1311 of the chamber 13. It will be appreciated that in other embodiments, the rail 41 may be disposed on the second side wall 1312, and the brush filaments 241 are located adjacent to one side of the second side wall 1312 and the rail 41 is also in sliding electrical connection. In such an embodiment, the guide rail 41 is formed with a circular track, and the roller 231 may be located within the circular track, within which the roller 231 moves in the case where the balancer movement 20 moves.

In this way, the brush wire 241 and the roller 231 share a circular track, the circular track can guide the movement of the roller while the brush wire 241 is connected, the roller 231 is located in the circular track, which can facilitate to control the movement track of the roller 231 and prevent the roller 231 from shifting, and the brush wire 231 and the roller 231 share a track, which can simplify the structure of the balancing assembly 100 without providing an additional guiding structure to guide the movement of the roller 231.

Referring to fig. 16-19, the balancing assembly 100 includes a transceiver 50 and a controller 60. The radio 50 comprises a first radio 51 and a second radio 52. The first wireless transceiver 51 is configured to be mounted in the first cavity 200, and the second wireless transceiver 52 is configured to be mounted in the second cavity 300. The first wireless transceiver 51 and the second wireless transceiver 52 are disposed opposite to each other at an interval, and the controller 60 is connected to the first wireless transceiver 51.

It will be appreciated that the controller 60 is connected to the first conductive track 411, the second conductive track 412, the first communication track 413 and the second communication track 414 by first conductors 61. The controller 60 may obtain power from the first and second wireless transceivers 51 and 52 and transmit the power to the first and second conductive rails 411 and 412 through the first wire 61, so that the balancer 20 may obtain power from the first and second conductive rails 411 and 412 through the first and second conductive brush filaments 2411 and 2412.

The controller 60 may communicate with the balancer 20 through the first wire 61, the first communication rail 413, the second communication rail 414, the first communication brush filaments 2413, and the second communication brush filaments 2414. Specifically, in one embodiment, the controller 60 may transmit a movement instruction of the balancer 20 to the first and second communication rails 413 and 414 through the first wire 61, so that the balancer 20 may acquire the corresponding movement instruction from the first and second communication rails 413 and 414 through the first and second communication brush filaments 2413 and 2414. In another embodiment, the balancer 20 may transmit current position information of the balancer 20 to the first and second communication rails 413 and 414 through the first and second communication brush wires 2413 and 2414, so that the controller 60 may acquire the current position information of the balancer 20 through the first wire 61 connected to the first and second communication rails 413 and 414. In other embodiments, other information and instructions may also be exchanged between the controller 60 and the balancer 20.

Specifically, the first transceiver 51 includes a first wire coil 511 and a first circuit board 512, and the second transceiver 52 includes a second wire coil 521 and a second circuit board (not shown). When power is supplied to the balancer 20, the second wire coil 521 is used to generate a varying magnetic field when power is applied, and the first wire coil 511 is used to generate an induction current when the varying magnetic field is sensed. The first cavity 200 is provided with a rotating shaft 600, the rotating shaft 600 can be rotatably connected with the second cavity 300, and a power device of the household appliance 1000 is connected with the rotating shaft 600 to drive the first cavity 200 to rotate. Referring to fig. 2, 16 and 19, a fixing frame 500 is fixedly connected to a rear end of the first cavity 200, and the fixing frame 500 is rotatably connected to the rotating shaft 600. The shaft 600 is a hollow shaft. The first wire coil 511 can be mounted at one end of the rotating shaft 600 through the first bracket 513, the first wire coil 511 is connected with the first circuit board 512 through the second conducting wire 514 penetrating through the inside of the rotating shaft 600, and the first circuit board 512 is connected with the controller 60. The second wire coil 521 can be installed on the outer surface of the second cavity 300 through the second bracket 522, the second wire coil 521 is connected with a second circuit board, the second circuit board is connected with a power line of the household appliance 1000, and the power line is connected with commercial power. As such, the external power is transmitted to the controller 60 in the form of wireless power transmission to transmit the power to the balancer 20 through the controller 60.

In the illustrated embodiment, the mount 500 is a tripod, which includes a first tripod 501, a second tripod 502, and a third tripod 503. Wherein, the first foot rest 501 is provided with a control panel 62, and the controller 60 is arranged on the control panel 62; the second leg frame 502 is mounted with a first circuit board 512; a third tripod 503 is mounted with a balance plate 504. Thus, the balance plate 504 can balance the eccentricity caused by the first circuit board 512 and the control plate 62, so that the tripod can keep balance and the vibration can be reduced.

Referring to fig. 5 and 20, the balancing assembly 100 includes a marking member 70 and a displacement detecting member 80. In the case where the balancer 20 moves in the chamber 13, the marker 70 and the displacement detecting member 80 relatively move, and the displacement detecting member 80 is used to detect the number of times the marker 70 passes the displacement detecting member 80, the number of times the marker 70 passes the displacement detecting member 80 being related to the position of the balancer 20. In this way, the displacement detecting member 80 can detect the number of times the marker 70 passes the displacement detecting member 80, and thus can acquire the moving distance of the balancer 20, so that the position of the balancer 20 can be determined.

It is understood that in the case where the balancer 20 moves in the chamber 13, the marker 70 and the displacement sensing member 80 relatively move to pass the displacement sensing member 80, and the number of times the marker 70 passes the displacement sensing member 80 is related to the position of the balancer 20. Therefore, the moving distance of the balancer 20 can be determined by detecting the number of times the identification member 70 passes the displacement detection member 80, and the position of the balancer 20 can be determined in combination with the initial balancing position of the balancer 20.

Specifically, the teeth of the coupling gear 2121 may be used as the marker 70, so that it may not be necessary to provide a marker additionally. Of course, the teeth of the tooth system 30 can also be used as the identifier 70. The displacement detecting member 80 includes at least one of a light sensor, a hall sensor, and an ultrasonic sensor. Hereinafter, the details will be described by taking the teeth of the coupling gear 2121 as the indicator 70 and the displacement detector 80 as an optical sensor.

The teeth of the combination gear 2121 are provided with grooves, and the teeth and the grooves are uniformly distributed in a staggered manner. The coupling gear 2121 is engaged with the tooth portion 30 to rotate, and the balancer 20 is moved by the rotation of the coupling gear 2121. In this case, the teeth of the coupling gear 2121 may serve as the identification member 70, and accordingly, the displacement sensing member 80 may be installed at a position on the equalizer 20 opposite to the teeth or grooves of the coupling gear 2121. When the coupling gear 2121 rotates, the displacement detecting member 80 is relatively immovable. During the rotation of the engaging gear 2121, the teeth and the grooves of the engaging gear 2121 pass through the displacement detecting member 80 alternately, so that the number of times the teeth of the engaging gear 2121 pass through the displacement detecting member 80, that is, the number of teeth of the engaging gear 2121 that pass through the displacement detecting member 80, can be detected. It will be appreciated that in other embodiments, the recess between two teeth may also be used as the identifier.

In the case that the displacement detecting member 80 is an optical sensor, the optical sensor includes a light emitting element and a light receiving element, and the light emitting element and the light receiving element may be disposed on the same side of the coupling gear or disposed on opposite sides of the coupling gear, respectively. Since the teeth of the coupling gear 2121 have a shielding effect on the light emitted from the light emitting member, and the grooves have no shielding effect on the light emitted from the light emitting member. In the case where the light emitting element and the light receiving element are provided on the same side of the coupling gear, the light receiving element may receive a strong light signal intensity reflected from the teeth, and no light signal intensity reflected from the grooves, or a weak light signal intensity reflected from the grooves (possibly due to light reflected from other components than the grooves), and regular pulse signals may be obtained through processing by the balance controller 251, the number of pulses is the number of teeth rotated in the coupling gear 2121, so that the moving distance of the balancer 20 may be obtained, and the position of the balancer 20 may be obtained in combination with the initial balance position of the balancer 20. In the case where the light emitting element and the light receiving element are respectively disposed on opposite sides of the coupling gear, the light receiving element may receive a strong light signal intensity passing through the recess, receive no or weak light signal intensity due to the light shielding by the teeth, and may process regular pulse signals through the balance controller 251, the number of pulses is the number of teeth rotated in conjunction with the gear 2121, thereby obtaining a moving distance of the balancer 20, and then the position of the balancer 20 may be obtained in conjunction with the initial balance position of the balancer 20. In one example, the light emitting element may be a light emitting diode (e.g., a visible light emitting diode, or an infrared light emitting diode) and the light receiving element may be a photodiode.

In other embodiments, alternate black and white stripes may be used as the markers 70, and correspondingly, the displacement detectors 80 may be photo sensors.

In the present embodiment, the chamber 13 is provided with an initial equilibrium position. The balance controller 251 is electrically connected to the displacement sensing member 80, and the balance controller 251 is used to determine the position of the balancer 20 according to the number of times the marker 70 passes the displacement sensing member 80 and the initial balance position. In this manner, the location of the balancer 20 is easily determined.

It will be appreciated that the initial equilibrium position of the balancer 20, in the absence of movement of the balancer 20, refers to the default position when the balancer 20 is stationary within the chamber 13. The balance controller 251 records an initial balance position, and determines the position of the balancer 20 in combination with the distance the balancer 20 has moved, when the balancer 20 starts moving from the default position. Specifically, the displacement detector 80 may output regular pulse signals according to the number of times that the identifier 70 passes through the displacement detector 80, the balance controller 251 may receive the pulse signals output by the displacement detector 80, process the pulse signals to obtain the moving distance of the balancer 20, and finally calculate the current position of the balancer 20 by combining the initial balance position of the balancer 20. The current position information of the balancer 20 may be transmitted to the controller 60.

In embodiments of the present invention, a plurality (two or more) of initial equilibrium positions may be provided in the chamber 13. In the case where there are a plurality of balancers 20 (two or more) in the chamber 13, each initial balancing position is stopped with a corresponding one of the balancers 20. In one embodiment, two initial equilibrium positions are provided in the chamber 13, with the number of balancers 20 being two. In the case where the two balancers 20 are not moved, one balancer 20 remains stationary at each initial balancing position. Preferably, the two initial equilibrium positions are arranged 180 degrees symmetrically. Thus, in the case where the balancer 20 does not move, the balance of the balance body 10 and thus the first chamber 200 can be maintained, preventing unnecessary vibration from being introduced when the first chamber 200 rotates. In other embodiments, the number of the initial equilibrium positions may be three or more, and the specific positions may be set as needed, and are not particularly limited herein.

Referring to fig. 5, the balance assembly 100 includes a calibration member 90 and a calibration detecting member 110. In the case where the balancer 20 moves in the chamber 13, the correcting member 90 moves relative to the correction detecting member 110, and the correction detecting member 110 detects the correcting member 90 to eliminate a position error of the balancer 20.

It is understood that, since the balancer 20 moves for a long time, an accumulated error may occur when the displacement sensing member 80 senses the number of rotations of the output shaft 2111 of the driving member 211 or the number of times the displacement sensing member 80 senses the passage of the identification member 70 through the displacement sensing member 80. When the moving distance of the balancer 20 is calculated by the information of the number of times of error, the determined position of the balancer 20 may be erroneous. Therefore, the position error of the balancer 20 can be eliminated by providing the correcting member 90 and the correction detecting member 110.

Specifically, when the calibration detecting member 110 passes each calibration member 90, information that it detects the calibration member 90 is transmitted to the balance controller 251. Further, the balance controller 251 acquires information of the position where the balancer 20 passes through the correction element 90, and sets the position where the balancer 20 is located to a value of 0, that is, the position can be regarded as a starting point to recalculate the moving distance of the balancer 20, so as to avoid that the position of the balancer 20 cannot be accurately determined due to accumulated distance errors caused by long-time movement of the balancer 20. In this embodiment, after the calibration detecting member 110 passes through each calibration member 90, the number of turns of the output shaft 2111 of the driving member 211 detected by the displacement detecting member 80 or the number of passes of the identification member 70 detected by the displacement detecting member 80 is fed back to the balance controller 251 again by way of a pulse signal from 0, and the moving distance of the balancer 20 by the balance controller 251 is calculated again, so as to obtain the accurate position information of the balancer 20 in the balance body 10.

Referring to fig. 21, two calibration members 90 are disposed in the chamber 13, the two calibration members 90 are symmetrically disposed at 180 degrees along the radial direction of the balance body 10, and the position of each calibration member 90 may correspond to an initial balance position. The correction member 90 is provided on the inner wall 131 of the chamber 13. One of the correction members 90 includes one correction portion that is convex, and the other correction member 90 includes two correction portions that are convex, and which correction member 90 passes through the balancer 20 is distinguished by the difference in structural characteristics, and thus it is possible to determine which initial balancing position the balancer 20 is located at.

The correction detecting member 110 may be one of a light sensor, an ultrasonic sensor, and a hall sensor. The correction detection part 110 triggers different pulse signals through the correction parts 90 with different structures, the number of pulses of the pulse signals is the same as that of the correction parts on the correction parts 90, so that the balancer 20 can be determined to pass through a certain correction part 90 according to the pulse signals output by the correction detection part 110, and the specific position of the balancer 20 in the cavity 13 can be determined. In this manner, the position of the balancer 20 can be positioned within the chamber 13. In other embodiments, the number of the correction members 90 may be three, four, or more than four, and each correction member 90 may include a different number of correction portions. The number and position of the correction pieces 90 and the number of correction portions of the correction pieces 90 may be adjusted according to circumstances, and are not limited to the above-described embodiment.

It should be noted that the correcting member 90 may correspond to an initial balance position, and after the operation of the balancer 20 is completed, the balancer 20 may be returned to the initial balance position by the cooperation of the correcting detecting member 110 and the correcting member 90, thereby resetting the balancer 20. In addition, the correcting member 90 may be mounted on a ring member 91, the tooth portion 30 is a tooth portion of a ring gear 31, and in the example of fig. 13, the ring member 91, the first rail holder 42, the ring gear 31, and the second rail holder 43 are arranged in parallel in the first sidewall 1311 of the chamber 13 in this order. It is understood that in other embodiments, the corrector 90 and/or the teeth 30 may be formed directly on the first sidewall 1311.

To sum up, the present invention provides a balance assembly 100 for a household appliance 1000. The household appliance 1000 comprises a first cavity 200 capable of rotating. The balancing assembly 100 includes a balancing body 10, a balancer 20, and a ring-shaped tooth 30. The balance body 10 is used for being installed in the first cavity 200, and an annular cavity 13 is arranged in the balance body 10. The inner wall 131 of the chamber 13 includes a first sidewall 1311 and a second sidewall 1312. The first sidewall 1311 and the second sidewall 1312 are disposed radially along the balance body 10, and the first sidewall 1311 is closer to the central axis Y of the chamber 13 than the second sidewall 1312. A balancer 20 is located within the chamber 13. The balancer 20 includes a power unit 21, the power unit 21 includes a driving member 211 and a coupling gear 2121, and the driving member 211 is connected to the coupling gear 2121. The teeth 30 are provided along the circumference of the balance body 10, the teeth 30 are provided on the first sidewall 1311, and the coupling gear 2121 meshes with the teeth 30.

In the balancing assembly 100 of the above embodiment, the balancer 20 is driven by the engagement of the coupling gear 2121 with the tooth portion 30, the engagement has the characteristics of high precision and stable transmission, and there is no risk of slipping, and the coupling gear 2121 is engaged with the tooth portion 30 of the first sidewall 1311 disposed near the central axis Y of the balancing body 10, so that it is possible to prevent the balancer 20 from being driven difficultly due to resistance caused by over-tightening of the engagement due to a centrifugal force generated when the first chamber 200 rotates, thereby ensuring smooth and stable movement of the balancer 20 in the chamber 13 when the first chamber 200 rotates, particularly, when the first chamber rotates at a high speed.
