The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0035] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] As shown in the drawings, Figures 1 to 11 In the embodiments of the present application, a barrel assembly is disclosed, comprising an outer barrel 3, an annular outer barrel cover 4 mounted on the top opening; an inner barrel 2 arranged in the outer barrel 3, a top opening of the inner barrel 2 is provided with a balance ring 1, the balance ring 1 is provided with a first shielding part 190 extending upward, and the extension end of the first shielding part 190 is higher than the inner circumferential edge of the upper surface of the outer barrel cover 4.

[0037] Through the above arrangement, the first shielding part 190 extending upward is arranged on the balance ring 1 to shield the gap between the balance ring 1 and the outer barrel cover 4, so as to avoid the case that small clothes fall into the inner and outer barrels 3 through the gap.

[0038] In the embodiments of the present application, the first shielding part 190 is an annular rib coaxial with the balance ring 1.

[0039] In the embodiment of the utility model, the outer bucket cover 4 coincides with the outer circumferential part of the balance ring 1 in the vertical direction, and the first shielding part 190 extends upward from the top of the inner circumferential part of the balance ring 1; preferably, the first shielding part 190 extends vertically upward.

[0040] Through the above setting, the first shielding part 190 and the balance ring 1 cooperate with the outer bucket cover 4 to form a zigzag channel, so that small clothes are more difficult to enter the spacing space between the inner bucket 2 and the outer bucket 3 through the gap between the balance ring 1 and the outer bucket cover 4.

[0041] In one embodiment of the utility model, the first shielding part 190 is connected to the top of the balance ring 1, and the connection position is arranged at a distance from the inner circumferential edge of the balance ring 1.

[0042] In another preferred embodiment of the utility model, the first shielding part 190 is flushly connected to the inner circumferential edge of the top of the balance ring 1; without reducing the radial width of the balance ring 1, the width of the overlapping surface of the balance ring 1 and the outer bucket cover 4 in the vertical direction is improved, thereby increasing the length of the horizontally extending gap formed by the cooperation of the outer bucket cover 4 and the balance ring 1, and further improving the effect of blocking small clothes; in addition, by increasing the outer diameter of the balance ring 1, the cross-sectional area of the balance ring 1 is increased without changing the length difference between the inner diameter and the outer diameter, and the maximum capacity of the internal balance liquid is increased, and in combination with the increase of the outer diameter of the balance ring 1, the size of the centrifugal force generated during the rotation of the balance ring 1 is significantly improved, thereby greatly improving the damping effect of the balance ring 1.

[0043] In the embodiment of the utility model, the distance between the first shielding part 190 and the inner circumferential edge of the outer bucket cover 4 is greater than the distance between the balance ring 1 and the outer bucket cover 4 in the vertical direction; so that the first shielding part 190 is farther away from the outer bucket cover 4 relative to the balance ring 1, preventing the first shielding part 190 from colliding with the outer bucket cover 4 due to the eccentric rotation of the inner bucket 2.

[0044] In the embodiment of the utility model, the outer bucket cover 4 comprises an annular fixed wall 402 extending upward from the top of the outer bucket 3, and an annular top wall 401 connected to the top end edge of the fixed wall 402, and the top wall 401 is inclined downward from the outer circumferential edge to the inner circumferential edge; the extension end of the first shielding part 190 is higher than the inner circumferential edge of the top wall 401.

[0045] By the above arrangement, by setting the top wall 401 extending downwardly inclined, to reduce the height of the inner periphery of the top wall 401, further reduce the spacing distance between the top wall 401 and the balance ring 1; in addition, to improve the impact resistance of the top wall 401 in the radial direction; then, the top of the outer bucket cover 4 is formed as a slope, so that during the dehydration process of the clothes treatment equipment, the water in the inner bucket 2 and the outer bucket 3 splashes onto the top wall 401 of the outer bucket cover 4, the water is guided to flow radially inwardly through the slope formed by the top wall 401, and then stopped at the extension end of the first shielding portion 190, so that the water flows into the spacing space between the inner bucket 2 and the outer bucket 3, and is directly discharged through the drain port at the bottom of the outer bucket 3, thereby avoiding the water flowing back to the inner bucket 2 and re-wetting the clothes.

[0046] In the embodiment of the application, the inner periphery of the top wall 401 is provided with a second shielding portion 403 extending downwardly bent, and the second shielding portion 403 coincides with the first shielding portion 190 in the radial direction; so that the second shielding portion 403 shortens the spacing between the outer bucket cover 4 and the balance ring 1 in the vertical direction; at the same time, when the balance ring 1 collides with the outer bucket cover 4, the second shielding portion 403 improves the contact area between the balance ring 1 and the outer bucket cover 4, and reduces the pressure when the two collide.

[0047] In another preferred embodiment of the application, the extension end of the first shielding portion 190 is lower than the outer periphery of the top wall 401 of the outer bucket cover 4.
