As such, the first wireless communication module 32 and the second wireless communication module 52 have a variety of options and are highly replaceable. The selection of the wireless gateway 34 is adapted to the type of the first wireless communication module 32 and the second wireless communication module 52. The wireless communication network is built by using the WiFi module in the ISM frequency band as an example. The control system 30 uses a WiFi module as the first wireless communication module 32, uses a WiFi gateway as the wireless gateway 34, and the balancer 50 uses a WiFi module as the second wireless communication module 52, and the second wireless communication module 52 and the first wireless communication module 32 in different balancers 50 can be combined into a wireless communication network through the wireless gateway 34 of the control system 30 to communicate with each other. The WiFi module can be networked by using a TCP/IP protocol so as to realize stable data communication. The operating frequency of the wireless communication module in the ISM band is above 2.4GHZ, and the electromagnetic field generated by the power motor 80 of the washing device 100 and the like does not interfere with the communication, so that the data transmission is stable and reliable.

In the present embodiment, the washing chamber 20 is rotatably located within the body 10. It is understood that in other embodiments, the washing chamber 20 and the body 10 may be connected in other manners, and are not limited in particular. In the embodiment of the present invention, the washing device 100 is used for washing clothes, etc., and the clothes are placed in the washing chamber 20. When the washing apparatus 100 is in operation (e.g., during a dehydration stage), the washing chamber 20 rotates at a high speed, and the laundry in the washing chamber 20 may be unevenly distributed and may be eccentric. When the washing chamber 20 rotates at a high speed, the washing apparatus 100 generates a large vibration. The balance ring 40 is connected and fixed to the washing chamber 20 and rotates with the washing chamber 20. Accordingly, the eccentric mass when the washing chamber 20 rotates can be offset by controlling the movement of the balancer 50 in the balancing ring 40. Specifically, the control system 30 acquires a vibration signal of the washing apparatus 100, and then generates a control command according to the vibration signal, the control command being transmitted to the corresponding balancer 50 through the wireless communication network to control the movement of the balancer 50. The control instructions include a target position of the balancer 50.
Specifically, the body 10 of the washing device 100 is provided with a door assembly (not shown) to close the washing chamber 20. The body 10 may include a housing (not shown) and a water containing chamber 12. The washing chamber 20 is rotatably provided in the water containing chamber 12. The water holding chamber 12 and the washing chamber 20 may be provided in a housing, and a door assembly may be provided on the housing to close the washing chamber 20 and the water holding chamber 12. The housing is optional, in some embodiments, the water containing cavity 12 can be directly exposed outside or embedded in a wall or a cabinet, and the door assembly is disposed on the water containing cavity 12 to close the washing cavity 20 and the water containing cavity 12. The washing chamber 20 may have a rotation axis X arranged horizontally, obliquely or vertically. That is, the rotation axis X of the washing chamber 20 is parallel, inclined or perpendicular to the horizontal plane. It will be appreciated that one or more balancing rings 40 may be disposed at any position of the washing chamber 20, with the balancing rings 40 rotating with the rotation of the washing chamber 20. The central axis of the balancing ring 40 is parallel to or coincides with the rotation axis X of the washing chamber 20, that is, the balancing ring 40 may be disposed coaxially with the washing chamber 20 or eccentrically with respect to the washing chamber 20. In the illustrated embodiment, washing device 100 is a drum washing machine. In other embodiments, the washing device 100 may be a pulsator washing machine.
Referring to fig. 3 and 4, in some embodiments, the washing chamber 20 has an axis of rotation X. The washing chamber 20 comprises a first end 22 and a second end 24 of the axis of rotation X. A balancing ring 40 is attached to each of the first end 22 and the second end 24. At least one balancer 50 is disposed within each of the balancing rings 40.
Therefore, the two ends of the washing cavity 20 along the rotation axis thereof can be connected with the balance rings 40, so that the effect of balancing the eccentricity of the washing cavity 20 is better. In the illustrated embodiment, the balancing ring 40 comprises a first balancing ring 402 and a second balancing ring 404, the washing chamber 20 has a horizontally arranged rotation axis X, the washing chamber 20 comprises a first end 22 and a second end 24 along the rotation axis X, the first balancing ring 402 is connected to the first end 22 of the washing chamber 20, the second balancing ring 404 is connected to the second end 24 of the washing chamber 20, and the first balancing ring 402 and the second balancing ring 404 are coaxially arranged with the washing chamber 20. Specifically, the second end 24 of the washing chamber 20 is fixedly coupled to the spider 60, the first balance ring 402 is threadedly coupled to the first end 22 of the washing chamber 20, and the second balance ring 404 is threadedly coupled to the spider 60. The water containing cavity 12 and the washing cavity 20 are both cylindrical, and the first end 22 of the washing cavity 20 is a front end and the second end 24 is a rear end. The front end may refer to the end facing the user. In other embodiments, the first end 22 or the second end 24 of the washing chamber 20 is provided with a balancing ring 40, or the balancing ring 40 is provided between the first end 22 and the second end 24.
Hereinafter, the first balancing ring 402 is connected to the first end 22 of the washing chamber 20, the second balancing ring 404 is connected to the second end 24, and two balancers 50 are disposed in the first balancing ring 402 and the second balancing ring 404, respectively.
The first balance ring 402 and the second balance ring 404 are substantially identical in structure except for the difference in the positions where they are coupled to the washing chamber 20. The first balance ring 402 is described in detail below as an example. The initial positions of the two balancers 50A and 50B within the first balancing ring 402 are symmetrically arranged in such a manner that the washing chamber 20 can be balanced in an unloaded state.
Referring to fig. 4 and 5, the first balancing ring 402 includes the end cap 42, the ring seat 44, the first ring gear 462, the second ring gear 464, and the carrier ring 48. The ring seat 44 and the carrier ring 48 together form a receiving cavity in which the balancers 50A and 50B perform a circular motion.
Referring to fig. 2 and 6, the balancer 50 includes a power module 54, a driving module 56, a control board 58, a bracket 51, a guide module 53, and a carrying module 55. Drive module 56 includes a first gear 562, a second gear 564, and a drive assembly 566, with first gear 562 and second gear 564 being symmetrically disposed on opposite sides of drive assembly 566. The power module 54 may be charged via wireless charging techniques. The drive assembly 566 may include a drive motor, and the power module 54 transmits power to the control panel 58, and the control panel 58 controls the forward, reverse, stop, etc. motion of the drive assembly 566 to control the movement of the equalizer 50. The power module 54, the driving module 56, the control board 58, the guide module 53, the carrying module 55, and the like are fixed on the bracket 51. The supporter 51 may be made of a thick stainless steel plate, and the supporter 51 may not be deformed during the entire operation of the balancer 50.
Referring to fig. 7, a first gear 562 and a second gear 564, which are symmetrically arranged, are engaged with the first ring gear 462 and the second ring gear 464 of the balance ring 40, respectively. The drive assembly 566 may be a two-stage drive for driving the first gear 562 and the second gear 564 in a circular motion along the first gear 462 and the second gear 464 throughout the balancer 50. Wherein the first gear 562 and the second gear 564 rotate in synchronization. The balancer 50 is provided at both ends thereof with guide blocks 53 for preventing the balancer 50 from directly rubbing against the inner wall of the ring seat 44 of the balancing ring 40, and the guide blocks 53 have rollers rotatably coupled to the inner wall of the ring seat 44. A carrier module 55 is secured under the drive assembly 566, and the carrier module 55 moves along the carrier ring 48 as the equalizer 50 moves. The washing chamber 20 performs a circular motion while rotating, and the carrying module 55 serves to bear a centrifugal force of the balancer 50 under the circular motion of the washing chamber 20. The carrier module 55 may be a carrier cart.
Referring to fig. 8, the balancer 50 further includes a first position sensor 572 and a second position sensor 574. The first position sensor 572 cooperates with the protrusions 442 on the inner wall of the ring seat 44 to identify position, while the second position sensor 574 is accurately positioned by identifying the number of teeth on the first gear 562 or the second gear 564. During the movement of the balancer 50, the first gear 562 and the second gear 564 rotate synchronously, and the numbers of teeth of the first gear 562 and the second gear 564 rotate are the same. At least one protrusion 442 cooperating with the first position sensor 572 may be distributed on the ring seat 44 to function as a position correction. The second position sensor 574 precisely determines the moving distance of the balancer 50 by calculating the number of teeth through which the first gear 562 or the second gear 564 rotates, thereby achieving precise positioning of the balancer 50.
In some embodiments, the balancer 50 is configured to communicate with the remaining balancers via a wireless communication network to obtain the location of the remaining balancers 50.
In this manner, when a plurality of balancers 50 are provided in the same balancing ring 40, the balancers 50 can communicate with each other to obtain the positions of the other balancers 50, thereby preventing the balancers 50 from colliding with each other during movement.
It can be understood that the control system 30 controls the movement of the balancers 50 through the wireless communication network according to the vibration signal of the washing apparatus 100, so as to prevent the two balancers 50 in the same balancing ring 40 from colliding with each other. The various balancers 50 communicate with each other via a wireless communication network, and may coordinate their positions and directions of movement with each other. Each balancer 50 transmits its current location to the other balancers 50 through a wireless communication network, thereby further preventing the balancers 50 in the same balancing ring 40 from colliding with each other during movement.
In some embodiments, body 10 includes water holding cavity 12, and washing cavity 20 is rotatably disposed in water holding cavity 12. The control system 30 includes a first control circuit 36. The first control circuit 36 is used for acquiring a vibration signal of the water containing cavity 12, determining a target position of the balancer 50 according to the current position and moving direction of the balancer 50 and the vibration signal, and sending the target position to the balancer 50 through a wireless communication network so as to move the balancer 50 to the target position.
Thus, the balancer 50 is controlled to move to the target position, so that the eccentric mass of the washing chamber 20 during rotation can be offset, thereby reducing the vibration level of the washing apparatus 100.
It will be appreciated that the water containing chamber 12 comprises a third end 122 and a fourth end 124 along the axis of rotation X of the washing chamber 20. When the washing chamber 20 rotates at a high speed, the washing device 100 generates a large vibration, and the third end 122 and the fourth end 124 of the water containing chamber 12 are greatly displaced. Therefore, the vibration signal of the water containing chamber 12 can be obtained by detecting the displacement of the third and fourth terminals 122 and 124, so that the target position of the balancer 50 can be determined according to the vibration signal of the water containing chamber 12 and the current position and moving direction of the balancer 50. The displacement may refer to a vibration amplitude.
In some embodiments, the balancer 50 is configured to transmit the current position of the balancer 50 to the first control circuit 36 via a wireless communication network during movement of the balancer 50 to the target position.
In this way, the current position of the balancer 50 is fed back to the control system 30 during movement, forming a closed loop control that ensures that the balancer 50 can move to the target position.
In some embodiments, the washing apparatus 100 comprises a vibration sensor 70, the vibration sensor 70 is disposed in the water containing cavity 12, and the first control circuit 36 is configured to collect a vibration signal from the water containing cavity 12 via the vibration sensor 70.
In this manner, the vibration signal of the water containing chamber 12 is collected by the vibration sensor 70, so that the target position of the balancer 50 can be determined based on the vibration signal. Specifically, the vibration sensor 70 can be disposed at the third end 122 and the fourth end 124 of the water containing cavity 12 for detecting the vibration signal of the third end 122 and the vibration signal of the fourth end 124. The third end 122 corresponds to the first gimbal 402, and the collected vibration signal is used to determine the target position of the balancer 50 in the first gimbal 402; the fourth end 124 corresponds to the second gimbal 404, and the acquired vibration signal is used to determine the target position of the balancer 50 within the second gimbal 404. The vibration sensor 70 may be an acceleration sensor or a displacement sensor. The displacement sensor may directly detect the displacement of the third and fourth terminals 122 and 124. The acceleration sensor can detect the acceleration of the third terminal 122 and the fourth terminal 124, and then calculate the displacement of the third terminal 122 and the fourth terminal 124 by integration.
Referring to fig. 2, in some embodiments, the washing apparatus 100 includes a power motor 80, and the power motor 80 is used for driving the washing chamber 20 to rotate. The control system 30 includes a first switch module 38 and the balancer 50 includes a second switch module 59. In the case where the washing apparatus 100 receives a signal for controlling the rotation of the washing chamber 20 and the balancer 50 is in the off state, the control system 30 is configured to transmit an activation signal to the second switching module 59 through the first switching module 38, and the second switching module 59 is configured to turn on the balancer 50 according to the activation signal.
Thus, when the balancer 50 is required to move to offset the eccentric mass when the washing chamber 20 rotates, the balancer 50 is turned on again, so that the power consumption of the balancer 50 can be reduced.
It can be understood that, in case of receiving the signal for controlling the rotation of the washing chamber 20, the control system 30 controls the power motor 80 to drive the washing chamber 20 to rotate, and as the rotation speed of the washing chamber 20 increases, the vibration amplitude of the body 10 will become larger. In case that the rotation speed is greater than the preset value, it is necessary to control the balancer 50 to move to offset the eccentric mass when the washing chamber 20 rotates. Accordingly, the balancer 50 may be activated to control the movement of the balancer 50 in case the washing apparatus 100 receives a signal for controlling the rotation of the washing chamber 20. The preset value may be 0 or a value greater than 0, for example, the preset value is 45 rpm.
In some embodiments, in case the rotation speed of the washing chamber 20 is less than a preset value or the power motor 80 is turned off, the control system 30 is configured to send a turn-off signal to the second switching module 59 through the first switching module 38, and the second switching module 59 is configured to turn off the balancer 50 according to the turn-off signal.
In this way, when the balancer 50 is not required to move, the balancer 50 is closed, and the amount of electricity of the balancer 50 is stored.
It can be understood that, in case that the rotation speed of the washing chamber 20 is less than the preset value, the vibration of the body 10 is small, and the movement of the balancer 50 may not be controlled to offset the eccentric mass when the washing chamber 20 rotates. Thus, the balancer 50 may be turned off to conserve power. The preset value is a value greater than 0, for example, the preset value is 40 rpm. Of course, the balancer 50 may be controlled to be closed in case the rotation speed of the washing chamber 20 is 0, that is, in case the rotation of the washing chamber 20 is stopped. When the power motor 80 is turned off, indicating the end of a certain washing stage, the washing chamber 20 may not immediately stop rotating due to inertia, but the rotation speed of the washing chamber 20 gradually decreases, and at this time, the vibration of the washing apparatus 100 is relatively small, so that the balancer 50 may be turned off when the power motor 80 stops rotating.
Further, the balancer 50 includes a power module 54 and a second control circuit 582, the power module 54 includes a battery 542 and a switch 544, the switch 544 connects the battery 542 and the second control circuit 582, the second switch module 59 is configured to control the switch 544 to be closed according to the activation signal and to be opened according to the closing signal, and the second control circuit 582 is configured to control the balancer 50 to move according to a control instruction of the control system 30 in a case where the switch 544 is closed.

After receiving the activation signal from the first switching module 38, the second switching module 59 analyzes the information to activate the balancer 50, so as to control the switching element 544 to close, thereby connecting the battery 542 with the second control circuit 582, so that the balancer 50 can start to operate, and the second wireless communication module 52 starts to operate. After waiting for all balancers 50 to operate, the second wireless communication module 52 and the first wireless communication module 32 start networking through the wireless gateway 34, and after the networking is successful, the control system 30 can control the movement of the balancers 50 through the wireless communication network.
When the washing apparatus 100 finishes the dehydration stage, the control system 30 transmits the information for turning off the balancer 50 to the first switch module 38, and the first switch module 38 converts the information for turning off the balancer 50 into a turn-off signal (wireless signal) and transmits the turn-off signal. After receiving the shutdown signal sent by the first switch module 38, the second switch module 59 analyzes the information to shut down the balancer 50, thereby controlling the switch 544 to be turned off, so that the balancer 50 can store power.
