The invention provides a pulsator mechanism for a washing machine and the washing machine, and aims to improve the washing effect of clothes, meet the washing requirement of users and improve the user experience.
Specifically, the washing machine provided by the invention is a pulsator washing machine, and comprises an outer tub and an inner tub arranged in the outer tub, wherein the pulsator mechanism comprises a pulsator arranged at the bottom of the inner tub, at least one spray hole arranged on the pulsator and a water blocking component arranged at the bottom of the pulsator, and the water blocking component can enable water to flow back and be sprayed into the inner tub through the at least one spray hole in the rotating process of the pulsator. The water retaining assembly can adopt a structure of a plurality of ribs or a structure of an impeller, and a person skilled in the art can flexibly set the specific structure of the water retaining assembly in practical application, so long as water can flow back through the water retaining assembly and be sprayed into the inner barrel through the spray hole, and clothes can vertically roll. In addition, the number of the spraying holes is preferably a plurality of, so that water sprayed from the bottom of the pulsator can uniformly act on the clothes in the inner tub, and the clothes can be continuously tumbled. Of course, the number of injection holes may be one, and those skilled in the art may flexibly set the specific number of injection holes in practical applications, and the number of injection holes may be changed without departing from the principle and scope of the present invention. The following describes the technical scheme of the invention in detail by combining the structure that the water retaining component is a plurality of ribs.
Preferably, as shown in fig. 1 to 3, the water blocking assembly includes a mounting member provided at the bottom of the pulsator 1 and a plurality of first ribs 2 circumferentially distributed around the mounting member, the plurality of first ribs 2 being capable of causing water to flow back during rotation of the pulsator 1. Wherein the mounting member may preferably be an annular baffle plate 3, and the injection holes 4 are annularly distributed around the annular baffle plate 3, and the annular baffle plate 3 may form a blocking effect on water so that the water can smoothly enter the inner tub through the injection holes 4. Of course, the mounting member may be other structural members, such as a mounting shaft, a mounting block, etc., and a specific structure of the mounting member may be flexibly set by those skilled in the art in practical applications, so long as a plurality of the first ribs 2 can be mounted by the mounting member. As shown in fig. 1 and 2, the plurality of first ribs 2 are preferably distributed around the annular baffle 3 in a turbine shape so that water is more likely to form a backflow during rotation of the pulsator 1.
It is further preferable that a return space is formed between two adjacent first ribs 2, and the injection hole 4 is provided in the return space. The number of the injection holes 4 in each return space may be one or more, and those skilled in the art can flexibly set the number of the injection holes 4 in each return space in practical applications, and the change of the spatial arrangement does not deviate from the principle and scope of the present invention. Further, as shown in fig. 1, 2, 4 and 5, the injection hole 4 in each of the backflow spaces is preferably provided at a position close to the annular barrier 3 so that water can flow from the rim of the pulsator 1 to the middle when it is refluxed, thereby allowing water to enter the inner tub through the injection hole 4. Of course, the above-described positions of the injection holes 4 in each of the backflow spaces are merely exemplary, and those skilled in the art can flexibly set the specific positions of the injection holes 4 in practical applications as long as backflow water can be injected into the inner tub through the injection holes 4.
It should be noted that the first rib 2 is fixedly connected to or integrally provided with the annular barrier 3. When the first rib 2 and the annular baffle 3 are in detachable fixed connection, the maintenance and the replacement of the first rib 2 can be facilitated, and when the first rib 2 and the annular baffle 3 are manufactured in an integrated mode, the unified manufacturing of the die can be facilitated.
Still further preferably, as shown in fig. 1 to 3, a second rib 5 is provided in the return space, the second rib 5 serving to shunt water in the return space. That is, a second rib 5 may be provided in each of the backflow spaces to divert the water in the backflow space, for example, in the structure shown in fig. 1 and 2, one second rib 5 may be provided in each of the backflow spaces, the water in the backflow space may be divided into two parts by the second rib 5, and the water of both parts may flow from the edge of the pulsator 1 to the middle portion when the pulsator 1 rotates, thereby being sprayed into the inner tub through the spraying holes 4 in the backflow space. Wherein the arrangement direction and shape of the second ribs 5 are preferably set to coincide or substantially coincide with the first ribs 2.
Preferably, at least one rib 6 is provided on the first rib 2, and the at least one rib 6 can increase the injection speed of water through the injection hole 4 when the rotation direction of the pulsator 1 is changed.

Alternatively, as shown in fig. 1 to 5, the injection hole 4 has a long strip shape. Of course, this is not restrictive, and a person skilled in the art may flexibly set a specific shape of the injection hole 4, such as a circular shape, an oval shape, or a rectangular shape, etc., in practical applications, as long as the backwater water can be injected into the inner tub through the injection hole 4, and the shape of the injection hole 4 is changed without departing from the principle and scope of the present invention.
In addition, as shown in fig. 1 to 5, the top of the pulsator 1 is provided with a plurality of protrusions 7 distributed in a ring shape, and water in the inner tub can rotate along with the pulsator 1 in the rotating process by the effect of the plurality of protrusions 7, so that acting force on transverse rotation of clothes is generated, and then the clothes are continuously rolled by vertical acting force generated by water jet of the injection hole 4, so that the washing effect of the clothes is improved to the greatest extent.
Thus far, the technical solution of the present invention has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present invention is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present invention, and such modifications and substitutions will fall within the scope of the present invention.
