Referring to fig. 1, fig. 1 is a schematic view of a drum assembly 100 according to an exemplary embodiment of the present application.

The drum assembly 100 provided herein may be applied to a drum washing machine.

The drum assembly 100 includes an outer tub 10, an inner tub 20, and a balance ring 30. The outer cylinder 10 includes a first end 101 and a second end 102 in an axial direction, the first end 101 being provided as a mounting end for mounting a power supply. In a practical application scenario, the first end 101 is set to face away from the rear end of the gate, and the second end 102 is set to face toward the front end of the gate. The outer tub 10 may be provided as a circular tub.

The inner tube 20 is provided inside the outer tube 10 and is rotatably provided with respect to the outer tube 10. The hollow part of the inner cylinder 20 is provided with a washing cavity 200, the wall of the inner cylinder 20 is provided with a water through hole 201, and the inner cylinder 20 and the outer cylinder 10 are coaxially arranged. The inner barrel 20 may be provided as a circular barrel. The balance ring 30 is disposed at an end of the inner cylinder 20 corresponding to the second end 102, that is, the balance ring 30 is disposed at an end of the inner cylinder 20 facing the door.

Referring to fig. 2, fig. 2 is a schematic diagram of a gimbal 30 according to an exemplary embodiment of the present application.

The balance ring 30 includes a water storage chamber 301 and a valve 302 for opening or closing the water storage chamber 301, and the valve 302 is configured to be opened by the water pressure in the washing chamber 200 and closed after the water pressure disappears. In an actual application scenario, when the water level in the washing chamber 200 is higher than the valve 302, the valve 302 is opened under the action of water pressure, and at this time, the water storage chamber 301 is communicated with the washing chamber 200, and water in the washing chamber 200 can flow into the water storage chamber 301.

As can be seen from the above description, the balance ring 30 is disposed at the end of the inner cylinder 20 opposite to the mounting end, the water storage cavity 301 is disposed inside the balance ring 30, and during transportation, the water storage cavity 301 of the balance ring 30 is empty, and at this time, the overall weight of the drum assembly 100 is small, and the transportation difficulty is small. When the balance ring is used, water can be injected into the water storage cavity 301 by utilizing water pressure, the weight of the balance ring 30 is increased, and at the moment, the weight of a motor arranged on the outer cylinder 10 can be balanced by utilizing the weight of the balance ring 30 after water addition, so that the balance weight requirement of the roller assembly 100 is met.

Referring to fig. 3, fig. 3 is an enlarged view of a portion a in fig. 2.

In one embodiment, the valve 302 includes a movable valve body 3020 and a compression spring 3022, where the compression spring 3022 is disposed in the water storage cavity 301, and one end of the compression spring 3022 is fixed, and the other end is connected to the valve body 3020. A valve body 3020 is located in the water storage chamber 301, sealing the water storage chamber 301 from the inside. The compression spring 3022 is compressively deformable, and the valve body 3020 seals the water storage chamber 301 by the urging force of the compression spring 3022. That is, the hydraulic pressure overcomes the elasticity of the compression spring 3022, so that the compression spring 3022 is compressed and deformed, and the compression spring 3022 can drive the valve body 3020 to move toward the inner side of the water storage chamber 301 after being compressed and deformed, so that the water storage chamber 301 is opened. After the water pressure disappears, the compression spring 3022 is restored to deform, and the valve body 3020 is pushed to reset, so that the water storage chamber 301 is closed. The valve 302 is simple in structure and convenient to implement. It should be noted that the compression spring 3022 needs to be set with reference to the water pressure in the washing chamber 200 to ensure that the valve body 3020 can be opened under the water pressure.

The manner of setting the water storage chamber 301 is not limited. For example, a plurality of water storage chambers 301 isolated from each other may be provided inside the balance ring 30, and each water storage chamber 301 may be opened and closed by one valve 302. In this embodiment, the water storage chamber 301 is provided as an integral communication structure. In particular, the water storage chamber 301 is configured as an annular chamber extending along the outer contour of the balance ring 30, which is more convenient to manufacture. And, the valve 302 may be provided in plurality, and the plurality of valves 302 may be provided at uniform intervals to collectively seal the water storage chamber 301. The plurality of valves 302 may increase the flow rate during fill and increase the fill rate.

Referring to fig. 4 to 6, fig. 4 is a schematic view illustrating the assembly of the balance ring 30 to the inner cylinder 20. Fig. 5 is an exploded view of the inner barrel 20 and the gimbal 30. Fig. 6 is an axial view of the gimbal 30 assembled to the inner barrel 20.

In the embodiment shown in fig. 4, the inner barrel 20 is a cylindrical barrel, and the shape of the balance ring 30 is adapted to the shape of the inner barrel 20, so that the integrity of the balance ring 30 and the inner barrel 20 in appearance can be achieved. The balance ring 30 is symmetrically arranged, so that the uniformity of the weight of each part of the balance ring 30 can be improved, and the vibration of the inner cylinder 20 during rotation can be reduced.

In one embodiment, the cross section of the balance ring 30 is square, and corners are rounded. Therefore, the surface of the corner is relatively smooth, sharp corners can be avoided, and damage to a user in the using process is avoided. The cross section of the balance ring 30 may be square or rectangular.

In one embodiment, to avoid the gimbal 30 taking up additional space, the end face of the gimbal 30 facing the second end 102 is flush with the end face of the inner barrel 20 at the second end. That is, the balance ring 30 is located inside the washing chamber 200 of the inner cylinder 20, and does not protrude outside the inner cylinder 20, thereby avoiding interference with components outside the inner cylinder 20.

In the embodiment shown in fig. 4 and 5, the outer shape of the balance ring 30 is the same as the shape of the inner wall of the inner cylinder 20, and may be all provided in a circular shape, and the outer wall of the balance ring 30 is connected with the inner wall of the inner cylinder 20. By this arrangement, the clearance between the balance ring 30 and the inner tube 20 in the radial direction is small, and the structural compactness is improved. The balancing ring 30 can be adhesively or otherwise attached to the inner barrel 20. In a specific embodiment, the balancing ring 30 is detachably connected to the inner cylinder 20 by a connection including, but not limited to, a snap fit, a bolt connection. The balance ring 30 may be made of plastic material, for example, but not limited thereto, by a blow molding process.

The present application also provides a drum washing machine (not shown). The drum washing machine includes a motor and the drum assembly 100 described above. The motor comprises a motor body and a motor shaft, wherein the motor body is arranged at the first end 101 of the outer cylinder 10, the motor shaft is connected with the inner cylinder 20, and the inner cylinder 20 can be driven to rotate.

In one embodiment, the drum washing machine is provided with a water injection process, a washing process, and a dehydration process, during which the valve 302 of the balancing ring 30 is opened by the water pressure of the washing chamber, and the water storage chamber 301 is filled with water, and at this time, the weight of the balancing ring 30 is increased. During washing and/or dewatering, the water level is low, the water pressure is low, the valve 302 is closed, the water storage cavity 301 is in a sealed state, water in the water storage cavity 301 cannot flow out, and at this time, the balance ring 30 can be used for balancing the weight of the motor.
