Problems solved by technology

This causes the metal ball or liquid to be far away from the rotation axis of the inner tub of the washing machine at the initial stage of dehydration, causing the inner tub of the washing machine to shift toward the metal ball or liquid accumulation, causing the inner tub to be unbalanced and sink to one side. It is easy to cause the rotation of the inner tub to be unstable, and the washing machine is not easy to start smoothly, resulting in damage to the washing machine

Embodiment 1

[0036] Such as figure 1 As shown, this embodiment introduces a balance ring, which includes a balance ring 4 with a hollow interior. The balance ring 4 is in the shape of a bowl. The bowl shape is a circle that gradually curves outward from the center, the middle part of the circle is arranged horizontally, and the portion close to the outer periphery gradually curves upward to form a bowl shape. The middle part of the balance ring 4 is provided with a perforation through both sides, and the perforation constitutes a mounting hole 8 for components such as the pulsator / inner tub shaft of the washing machine to pass through the balance ring 3 .

[0037] Such as figure 2 As shown, in this embodiment, the balance ring 4 is composed of a bowl-mounted upper end cover 42 and a lower end cover 41 buckled at a certain distance, and the middle part of the upper end cover 42 and the lower end cover 41 is provided with a mounting hole. 8 through-holes. The side of the upper end cover...

Embodiment 2

[0049] In this embodiment, the balance ring 4 is provided with at least one drainage hole 6 , and the drainage hole 6 is provided through both sides of the balance ring 4 . The drain holes 6 are uniformly arranged around the center of the balance ring 4 so that the center of gravity of the balance ring 4 is the center.

[0050] In this embodiment, the balance ring 4 is provided with a plurality of drain holes 6 of the same shape, preferably six. The drainage holes 6 are uniformly distributed in the area B of the balance ring 4 at equal intervals. There are certain gaps between the drainage holes 6 that the metal balls can pass through, so that the metal balls 5 can pass through the B area and shuttle between the A area and the C area.

[0051] In this embodiment, the opposite ends of the drain hole 6 of the balance ring 4 are respectively provided with mounting ribs protruding into the drain hole 6 , and bolt holes 7 are provided on the mounting ribs. Bolts pass through the ...

Embodiment 3

[0053] In this embodiment, the lower end cover 41 and / or the upper end cover 42 of the chamber 9 constituting the balancing ring are provided with reinforcing ribs 43 , and the reinforcing ribs 43 are extended to the interior of the chamber 9 . The distance between the top surface of the reinforcing rib 43 and the lower end cover 41 needs to be greater than the diameter of the metal ball 5 .

[0054] In this embodiment, in the region B of the chamber 9 of the balance ring, the lower end cover 41 is provided with columnar reinforcing ribs 43 that arch toward the interior of the chamber 9 . The distance between the top surface of the reinforcing rib 43 and the lower end cover 41 needs to be greater than the diameter of the metal ball 5, so that after the metal ball 5 is blocked by the reinforcing rib 43, the metal ball 5 rolls over from both sides of the reinforcing rib 43, so that The metal ball 5 shuttles back and forth between the A zone and the C zone. In this embodiment, a...

Abstract

The invention relates to the field of washing machines, in particular to a balance ring and a washing machine. The balance ring is mounted at the bottom of an inner drum of the washing machine; the balance ring is characterized in that the balance ring adopts a bowl structure low in center and high in periphery; a mounting hole used for allowing an impeller / an inner drum shaft to pass through is formed in the center of the balance ring; the balance ring is provided with a hollow cavity; at least one metal ball is arranged inside the cavity; a path used for allowing the metal ball to roll between the center and the periphery is formed in the cavity. The washing machine adopting the balance ring comprises an inner drum, wherein an inner drum base is arranged at the bottom of the inner drum; the balance ring is mounted on the inner drum base. By arranging the balance ring on the inner drum base of the washing machine, when the washing machine is in dehydration starting, the rectified metal ball is positioned close to the axial center of the inner drum, so that the unbalance rectifying capability of the washing machine is improved, the dehydration bearing capacity of the washing machine is improved, vibration and voice of the washing machine are reduced.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a balance ring and a washing machine. Background technique [0002] In the traditional structure of the liquid balance ring, due to the height and width design limitations of the inner barrel, the balance ring cannot be too large, so the liquid filling volume is limited. During the dehydration process of the washing machine, if the unbalanced load of the clothes exceeds the imbalance correction ability of the liquid balance ring, the washing machine cannot be started normally, or the phenomenon of loud vibration and loud noise will occur. [0003] For example, the Chinese patent application number CN201210377960.0 for a washing machine with a balancer discloses a washing machine with a balancer which can be used universally regardless of the size of the drum. The washing machine includes: a cabinet; a drum rotatably provided in the cabinet; an annular groove provided on the drum;...
