The traditional pulsator washing machine adopts a form of combining an inner barrel and an outer barrel to realize washing and dewatering functions. Therefore, dirt is easily stored and accumulated between the inner barrel and the outer barrel of the traditional washing machine, and bacteria are bred to be not beneficial to body health. The washing barrel of the washing machine without the outer barrel is of a single barrel structure, is different from the inner barrel body of the traditional washing machine, and is not provided with regularly distributed water permeable holes, a totally enclosed barrel wall is adopted, so that the health of washing water is ensured only in the inner barrel, but when the washing is finished and the dewatering is carried out, the inner barrel of the washing machine rotates at high speed to enable the water to move upwards, and how to drain the dewatered water is a problem to be solved.

The drainage runner is arranged on the balance ring main body, so that the drained washing water can be drained into the dewatering runner of the washing barrel during dewatering, and on the basis of not influencing the basic function of the balance ring, the structure of the balance ring is simply improved, so that the balance ring can be better combined with a single-barrel washing machine, and the dewatering requirement of the single-barrel washing machine is met. The washing machine simplifies the whole structure and can meet the requirement of the dewatering function of the washing machine. The invention is described in detail below with reference to specific examples:

as shown in fig. 1 and 2, the present invention provides a balance ring of a washing machine, preferably used in a single-tub washing machine, the balance ring having a drainage channel formed therein, the drainage channel having a water inlet and a water outlet; the water inlet enables the washing water to enter the drainage channel when the washing machine is dehydrated and to be discharged from the water outlet.

Preferably, the balance ring of the washing machine comprises a balance ring main body 1, the balance ring main body 1 is of an annular structure, an annular cavity is formed inside the balance ring main body 1, and a balance substance, such as a balance liquid, is filled in the annular cavity.

A drainage flow channel 11 is further formed in the balance ring main body 1, the drainage flow channel 11 is separated from the annular cavity, a water inlet 111 of the drainage flow channel 11 is formed on the radial inner peripheral wall of the balance ring main body 1, and a water outlet 112 of the drainage flow channel 11 is formed on the axial end face of the balance ring main body 1. Preferably, the annular cavity is located at an upper side of the drain flow passage 11 in the axial direction of the balance ring body 1, i.e., the position of the water inlet 111 is lower than that of the annular cavity, so as to avoid interference between the drain flow passage 11 and the annular cavity.

The balance ring of the washing machine further comprises a water retaining ring 13, the water retaining ring 13 is located on the upper side of the water inlet 111, and the water retaining ring 13 is in an annular structure extending to the radial inner side of the balance ring body 1, such as an annular baffle structure, or an annular convex structure with other shapes. Further, in a preferred embodiment, the water guard ring 13 is flush with the upper side edge of the water inlet 111, so that the washing water is prevented from continuously rising over the water inlet 111. Preferably, the water retaining ring 13 and the balance ring body 1 are integrally formed, or the water retaining ring 13 is an independent component and is formed separately from the balance ring body 1 and then fixedly connected to the inner circumferential wall of the balance ring body 1.

The drainage flow path 11 is preferably an arc-shaped flow path to reduce resistance of the flow path to water flow, for example, the drainage flow path 11 forms an arc-shaped flow path which is bent downward from the water inlet 111 to the water outlet 112. Further preferably, the opening area of the water inlet 111 is larger than the opening area of the water outlet 112, and an inclined surface is formed inside the drainage channel 11 from the water inlet 111 to the water outlet 112. For example, the opening of the water inlet 111 increases along the circumferential direction of the balance ring body 1, so that on one hand, the water inflow can be increased, and on the other hand, the inclined surface formed in the drainage channel 11 also guides the water flow, so that the water flow flows out through the water outlet 112 more quickly. Or, in other embodiments, the drainage channel 11 may also extend a certain length along the circumferential direction inside the balance ring body 1, that is, the water inlet 111 and the water outlet 112 of the drainage channel 11 are arranged at a certain angle in the circumferential direction of the balance ring body 1, so that the arrangement may enable water to enter into the drainage channel 11 and flow towards the water outlet 112 and flow out from the water outlet 112 under the inertia effect, and further facilitate the water flow to flow out.

The balance liquid amount in the first annular cavity 121 is 35-60% of the volume of the first annular cavity 121; the balance liquid in the second annular cavity 122 accounts for 35% -60% of the volume of the second annular cavity 122, so that the balance liquid in the first annular cavity 121 and the balance liquid in the second annular cavity 122 can normally flow, and when the dewatering device rotates, in order to ensure that a cylinder is not collided, the balance liquid can rapidly move to the opposite eccentric direction.

As shown in fig. 3 and 4, in another embodiment, the water outlet 112 of the drainage channel 11 may also be formed on the outer peripheral wall of the balance ring main body 1, and at this time, a lower annular cavity 12 'is also formed on the lower side of the drainage channel 11, and preferably, the lower annular cavity 12' may be divided into two independent cavities, i.e., a radial inner side and a radial outer side, and both the upper side and the lower side of the drainage channel 11 are formed with annular cavities, i.e., both the upper side and the lower side of the drainage channel 11 can play a balance role, so as to improve the balance role of the balance ring. Preferably, the inner independent cavity of the lower annular cavity 12 'communicates with the first annular cavity 121 and the outer independent cavity of the lower annular cavity 12' communicates with the second annular cavity 122.

The invention also provides a washing machine which is a single-barrel washing machine and comprises a washing barrel 2, wherein the open end of the washing barrel 2 is provided with the washing machine balance ring. A dehydration flow passage 21 is arranged on the wall of the washing barrel 2, the inlet of the dehydration flow passage 21 is positioned at the opening end of the washing barrel 2, and the inlet of the dehydration flow passage 21 is communicated with the water outlet 112 of the drainage flow passage 11.

Correspondingly, the water outlet 112 of the drainage channel 11 is formed on the axial end face of the balance ring body 1 at this time, so as to be conveniently communicated with the dehydration channel 21.

Further, in another embodiment, the dewatering water flow path may be disposed outside the washing tub 2, and is formed by an outer wall of the washing tub 2 and a baffle 23, in this embodiment, the water outlet 112 of the drainage flow path 11 is formed on an outer wall surface of the balance ring main body 1, and the baffle 23 may extend to the water outlet 112 to communicate the water outlet 112 with the dewatering flow path 21.
