Specifically, the laundry treating apparatus 1 may further include a cabinet, and the tub 30 is provided inside the cabinet.

The inner cylinder is provided with an axial placement space with one side open, the open side of the placement space defines a clothes putting opening, and the open side of the inner cylinder and the open side of the outer cylinder are positioned on the same axial side, so that a user can conveniently put clothes into the inner cylinder through the clothes putting opening or take the clothes away from the inner cylinder through the clothes putting opening.

Alternatively, when the laundry treating apparatus 1 is a washing machine, the rotation of the inner tub with respect to the outer tub 30 may be performed such that the laundry is continuously turned over, thereby performing washing, dehydrating, etc. operations of the laundry in the inner tub.

Alternatively, when the laundry treating apparatus 1 is a dryer, the inner drum rotates relative to the outer drum 30, so that the laundry can be turned over continuously, which is advantageous for improving the drying effect of the laundry in the inner drum, and avoiding the problem of poor drying effect caused by the fact that the laundry is accumulated and cannot be turned over.

Optionally, when the laundry treatment apparatus 1 is a washing and drying integrated machine, the inner drum rotates relative to the outer drum 30, so that the laundry can be turned over continuously, operations such as washing and dewatering the laundry in the inner drum can be realized, and drying effects on the laundry in the inner drum can be improved, so that the problem of poor drying effects caused by incapability of turning due to accumulation of the laundry is avoided.

The driving part is connected to the inner cylinder for driving the inner cylinder to rotate, and specifically, as shown in fig. 3 to 4, the bottom of the outer cylinder 30 has a connection hole 302, one end of the driving part is connected to the inner cylinder through the connection hole 302, and the other end of the driving part is located at the outer side of the outer cylinder 30, thereby driving the inner cylinder to rotate. Specifically, the driving part may include a driving motor (not shown) and a connection shaft 40, one end of the connection shaft 40 is connected to the inner cylinder through the connection hole 302, the other end of the connection shaft 40 is located at the outer side of the outer cylinder 30 and connected to the driving motor located at the outer side of the outer cylinder 30, the driving motor drives the connection shaft 40 to rotate, and the rotation of the connection shaft 40 drives the rotation of the inner cylinder.

The balancer 20 is provided on the inner cylinder, and the balancer 20 extends in a ring shape in the circumferential direction of the inner cylinder. Specifically, in some alternative embodiments of the present invention, the front portion of the inner barrel is provided with a balancer 20, the middle portion of the inner barrel is provided with a balancer 20, or the rear portion of the inner barrel is provided with a balancer 20. Of course, the invention is not so limited, and in alternative embodiments, both the front of the inner barrel and the rear of the inner barrel are provided with balancers 20. The specific arrangement positions and the number of the balancers 20 on the inner cylinder may be set according to actual needs, and the present invention is not particularly limited.

By providing the balancer 20 on the inner cylinder, the eccentricity of the inner cylinder can be compensated for, and the reliability of the inner cylinder can be improved.

The power supply system 10 may electrically connect the main control board and the balancer 20 to supply power to the balancer 20, or to implement signal transmission between the balancer 20 and the main control board, or to both supply power to the balancer 20 and implement signal transmission between the balancer 20 and the main control board.

In some embodiments, the power supply system 10 may electrically connect the main control board and the balancer 20 through wires (for example, the external wires and the wires 103 described below), so as to supply power to the balancer 20 through wires, so that the motor driving the balancing module 203 of the balancing module 203 in the housing 201 of the balancer 20 moves in the housing 201 to move to a side of the inner cylinder where the load is small when the inner cylinder rotates, so as to avoid the eccentric problem of the inner cylinder, while the signal transmission between the balancer 20 and the main control board may be in a wireless manner, particularly, bluetooth, infrared, etc., so that the signal transmission between the balancer 20 and the main control board is convenient for the main control board to know the position of the balancing module 203, and the moving direction of the balancing module 203, thereby further facilitating the control of the balancing module 203.

In other embodiments, the power supply system 10 may electrically connect the main control board and the balancer 20 through lines (such as the external wiring and the wiring 103 described below), so that signal transmission between the balancer 20 and the main control board is realized in a wired manner, and the signal transmission between the balancer 20 and the main control board is convenient for the main control board to know the position of the balancing module 203 and the moving direction of the balancing module 203, thereby further facilitating control over the balancing module 203. The balancer 20 may be powered by wireless (e.g., coil charging) so that the motor driving the balancing module 203 of the balancing module 203 in the housing 201 of the balancer 20 moves in the housing 201 to move to the side of the inner cylinder with less load when the inner cylinder rotates, thereby avoiding the problem of eccentric movement of the inner cylinder.

In other alternative embodiments, the power supply system 10 may electrically connect the main control board and the balance device 20 through lines (such as the external wiring and the wiring 103 described below), so as to realize signal transmission between the balance device 20 and the main control board and power supply to the balance device 20 in a wired manner, where the signal transmission between the balance device 20 and the main control board is convenient for the main control board to know the position of the balance module 203 and the movement direction of the balance module 203, thereby further facilitating control over the balance module 203. And the power supply to the balancer 20 facilitates the motor driving the balancing module 203 of the balancing module 203 in the housing 201 of the balancer 20 to move in the housing 201 to the side of the inner cylinder where the load is small when the inner cylinder rotates, avoiding the problem of the eccentricity of the inner cylinder.

Specifically, referring to fig. 2 and 7, the power supply system 10 includes a conductive member assembly 101 and a conductive loop assembly 102. Wherein the conductive member assembly 101 includes a conductive member 1011 (for example, the conductive member 1011 is a carbon brush or a copper wire), the conductive member 1011 is electrically connected to the conductive member 1022, one of the conductive member assembly 102 and the conductive member assembly 101 is stationary with respect to the outer cylinder 30, one of the conductive member assembly 102 and the conductive member assembly 101 is adapted to be electrically connected to the main control board through an external connection wire, the other of the conductive member assembly 102 and the conductive member assembly 101 rotates in synchronization with the inner cylinder, and the other of the conductive member assembly 102 and the conductive member assembly 101 is electrically connected to the balancer 20 (for example, a first connection terminal hereinafter) through a trace 103, and the conductive member 1011 and the conductive member 1022 are always kept in contact to achieve an electrical connection relationship when the inner cylinder rotates, so that it is known that the inner cylinder is rotatable with respect to one of the conductive member assembly 102 and the conductive member assembly 101, the other of the conductive member assembly 101 is stationary with respect to the conductive member assembly 102, so that the conductive member assembly 101 has a relative rotation relationship with the main control board, and the conductive member 1011 and the conductive member 1022 are always kept in contact with the balancer 20 regardless of the rotation of the inner cylinder, thereby achieving an electrical connection relationship between the main control board and the balancer 20.

Specifically, in some embodiments, the conductive member assembly 101 is stationary relative to the outer cylinder 30, that is, the inner cylinder is rotatable relative to the conductive member assembly 101, as shown in fig. 7, the conductive member 1011 of the conductive member assembly 101 has a wiring portion 10111, the wiring portion 10111 is electrically connected to the main control board through an external wiring, and since the outer cylinder 30 and the main control board are stationary, the conductive member assembly 101 is also stationary, so that there is no problem of winding on the external wiring connected between the wiring portion 10111 and the main control board.

The conductive ring assembly 102 rotates synchronously with the inner cylinder, that is, the conductive ring assembly 102 rotates relative to the outer cylinder 30 and the conductive member assembly 101, the conductive ring 1022 of the conductive ring assembly 102 is connected with the balancer 20 through the wiring 103, and the wiring 103 connected between the conductive ring 1022 of the conductive ring assembly 102 and the balancer 20 does not have any winding problem because the conductive ring assembly 102, the inner cylinder and the balancer 20 rotate synchronously.

Meanwhile, under the condition that the inner cylinder rotates, the conductive piece 1011 of the conductive piece assembly 101 and the conductive ring 1022 of the conductive ring assembly 102 are always matched and electrically connected, so that the electric connection relationship between the main control board and the balancer 20 can be realized, and when the inner cylinder rotates, power is supplied to the balancer 20, signal transmission between the main control board and the balancer 20 is realized, and the like.

The static implementation of the conductive member assembly 101 with respect to the outer tub 30 may be various, specifically, the conductive member assembly 101 may be mounted on the outer tub 30 or the conductive member assembly 101 may be mounted on the casing of the laundry treating apparatus 1, etc. as one implementation, however, the present invention is not limited thereto, and the conductive member assembly 101 may be mounted on other static components of the laundry treating apparatus 1, so long as the conductive member assembly 101 is convenient to cooperate with the conductive ring assembly 102.

The manner in which the conductive ring assembly 102 rotates in synchronization with the inner barrel can be varied, and in particular, the conductive ring assembly 102 can be mounted on a drive member. Alternatively, the conductive ring assembly 102 may be mounted on a portion of the connection shaft 40 of the driving part outside the outer cylinder 30, and the conductive ring 1022 surrounds the outer circumference of the connection shaft 40; or the conductive ring assembly 102 may be mounted on the rotor of the drive motor of the drive member, with the conductive ring 1022 encircling the outer periphery of the connecting shaft 40; alternatively, the conductive ring assembly 102 may be mounted on other parts of the driving member that rotate synchronously with the connecting shaft 40, and the conductive ring 1022 surrounds the outer circumference of the connecting shaft 40, so long as the synchronous rotation of the conductive ring assembly 102 and the inner cylinder can be ensured.

In other embodiments, the conductive ring assembly 102 is stationary relative to the outer barrel 30, that is, the inner barrel is rotatable relative to the conductive ring assembly 102, the conductive ring 1022 of the conductive ring assembly 102 is electrically connected to the main control board through the external connection, and since the outer barrel 30 and the main control board are stationary, the conductive ring assembly 102 is stationary, and thus the external connection between the conductive ring 1022 and the main control board is not a winding problem.

Also, the conductive member assembly 101 rotates in synchronization with the inner cylinder, that is, the conductive member assembly 101 rotates with respect to the outer cylinder 30 and the conductive ring assembly 102, the conductive member assembly 101 has the wiring portion 10111, the wiring portion 10111 is connected with the balancer 20 through the wiring 103, and since the conductive member assembly 101, the inner cylinder and the balancer 20 rotate in synchronization, the wiring 103 connected between the wiring portion 10111 of the conductive member assembly 101 and the balancer 20 does not have a winding problem.

Meanwhile, under the condition that the inner cylinder rotates, the conductive piece 1011 and the conductive ring 1022 are always matched and electrically connected, so that the electric connection relationship between the main control board and the balancer 20 can be realized, and when the inner cylinder rotates, power is supplied to the balancer 20, signal transmission between the main control board and the balancer 20 is realized, and the like.

The stationary implementation of the conductive ring assembly 102 with respect to the outer tub 30 may be varied, and in particular, the conductive ring assembly 102 may be mounted on the outer tub 30, and the conductive ring 102 may be mounted on the casing of the laundry treating apparatus 1 in a ring shape along the outer circumference of the connection shaft 40, or the like, as one implementation, however, the present invention is not limited thereto, and the conductive ring assembly 102 may be mounted on other stationary components of the laundry treating apparatus 1, as long as the conductive member assembly 101 is conveniently mated with the conductive ring assembly 102.

The manner in which the conductor assembly 101 rotates in synchronization with the inner cylinder may be various, specifically, the conductor assembly 101 may be mounted on the driving member, specifically, the conductor assembly 101 may be mounted on a portion of the connecting shaft 40 of the driving member located outside the outer cylinder 30, or the conductor assembly 101 may be mounted on a rotor of a driving motor of the driving member, or the conductor assembly 101 may be mounted on other members of the driving member that rotate in synchronization with the connecting shaft 40, as long as the synchronous rotation of the conductor assembly 101 and the inner cylinder can be ensured.

Regardless of whether the conductive member assembly 101 is stationary relative to the outer cylinder 30 or the conductive ring assembly 102 is stationary relative to the outer cylinder 30, when the inner cylinder rotates, different circumferential portions of the conductive ring 1022 are periodically in contact with the conductive member 1011, and since the conductive ring 1022 is formed in a ring shape, the entire conductive ring 1022 is always in contact with and electrically connected to the conductive member 1011 when the inner cylinder rotates.

In the related art, power and communication are generally supplied to the balancing module 203 in the balancer 20 by wireless transmission, however, the wireless transmission has problems of high cost, poor structural reliability, and the like.

In view of this, according to the laundry treating apparatus 1 of the embodiment of the present invention, by providing the power supply system 10 and one of the conductive member assembly 101 and the conductive ring assembly 102 is stationary with respect to the outer tub 30 and electrically connected to the main control board through the outer wiring, the other of the conductive member assembly 101 and the conductive ring assembly 102 rotates in synchronization with the inner tub and is electrically connected to the balancer 20 through the wiring 103, and the conductive ring 1022 and the conductive member 1011 are always contacted to achieve the electrical connection relationship when the inner tub rotates, thereby achieving the power supply to the balancer 20 and/or the signal transmission between the balancer 20 and the main control board in a wired manner, with higher reliability and simple structure, which is advantageous for reducing the cost. In addition, by using the conductive member 1011 as an electrical connection member of the power supply system 10, it is advantageous to ensure that the conductive ring 1022 and the conductive member 1011 always maintain a good electrical connection relationship.

In some embodiments of the present invention, as shown in fig. 5 to 6, the connection shaft 40 is formed with a routing channel 401 penetrating the connection shaft 40 in an axial direction of the connection shaft 40, and the routing 103 is electrically connected with the balancer 20 after passing through the routing channel 401. Specifically, for example, the conductive member assembly 101 is stationary relative to the outer cylinder 30, the conductive ring assembly 102 rotates in synchronization with the inner cylinder, one end of the trace 103 is connected to the balancer 20 (for example, to a first connection terminal of the balancer 20 described below), and the other end of the trace 103 passes through the trace passage 401, then protrudes out of the trace passage 401, and is connected to the conductive ring 1022 of the conductive ring assembly 102. For another example, the conductive ring assembly 102 is stationary relative to the outer cylinder 30, the conductive member assembly 101 rotates synchronously with the inner cylinder, one end of the trace 103 is connected to the balancer 20 (for example, to a first connection terminal of the balancer 20 described below), and the other end of the trace 103 passes through the trace channel 401 and then extends out of the trace channel 401 and is connected to the brush head 10113 of the conductive member 1011 of the conductive member assembly 101. Therefore, the structure is simple, the length of the wire 103 is shortened, the problem that the wire 103 is wound when the inner barrel rotates is avoided, meanwhile, the wire 103 channel can also play a role in protecting the wire 103, and the problem of short circuit is avoided.

In some alternative embodiments, the conductive ring 1022 is disposed around the outer circumference of the connection shaft 40, and the central axis of the conductive ring 1022 is disposed coaxially with the rotational center line of the inner cylinder, so as to facilitate ensuring that the conductive ring 1022 and the conductive element 1011 are always in electrical connection.
