Description

A washing machine impeller

technical field

The invention belongs to the technical field of washing machines, and particularly relates to a washing machine pulsator.

Background technique

With the rapid growth of the number of people living alone, people are increasingly reluctant to use public washing machines and the great development of social productivity, miniaturized washing machines are becoming more and more popular. The pulsator structure is more suitable for the miniaturization of the washing machine than the drum structure. The pulsator washing machine is easy to operate, saves time and electricity, and occupies a small space, so it is very popular in the market. However, because the mini washing machine has few modes and programs, no complex transmission structure, and no inverter motor, the mini washing machine cannot customize different washing modes and processes for different types of laundry.

SUMMARY OF THE INVENTION

In order to overcome the deficiencies of the above-mentioned existing functional technologies, the purpose of the present invention is to provide a washing machine pulsator suitable for a mini washing machine, which has the characteristics of practicality, convenience and simple structure, and can meet various washing needs by adding additional structures to the pulsator. .

In order to achieve the above purpose, the technical scheme adopted in the present invention is: a washing machine pulsator, comprising a pulsator body, and three roller bases are arranged on the pulsator body; the top of each roller base is provided with a rotatable washing roller, close to A circular groove is opened at the center of the pulsator body, and a triangular groove is opened near the edge of the pulsator body.

The rotatable washing roller is a triangular body, and a washing convex rib is installed on the three sides of the triangular body; .

One end of the three roller bases points to the center of the pulsator body, and the other end of the three roller bases points to the outer edge of the pulsator body; the angle between the ends of the two roller bases that point to the center of the pulsator body is 120 °.

The end of the rotatable washing roller pointing to the center of the pulsator body is connected to one end of the circular shaft; the other end of the circular shaft is installed in the circular groove of the roller base near the center of the pulsator body 1 .

The circular shaft sleeve is provided with a spring.

One end of the rotatable washing roller pointing to the outer edge of the pulsator body is fixedly connected with one end of the triangular shaft, and the other end of the triangular shaft is set in the triangular groove at the outer edge of the pulsator body 1 .

The beneficial effects of the present invention are:

Three kinds of ribs with different materials and structures are installed on the rotatable washing roller to adapt to different types of laundry. The three kinds of ribs are hard plastic ribs, rubber ribs and ribs with brushes on the surface. The hard plastic rib is used to wash the general laundry; the rubber rib is used to wash the laundry with hard objects such as metal, which can prevent the rib and the laundry from rigid collision and cause damage and reduce washing noise; Ribs with soft brush for stubborn stains.

The triangular shaft of the present invention can be inserted into the triangular groove every time it rotates 120 degrees, which ensures the accurate switching of the washing ribs on three sides. Since the other end is equipped with a spring, it can automatically reset after switching. The triangular shape of the shaft and the groove can lock the rotatable washing roller to ensure that the rotatable washing roller does not rotate during the washing process. The structure has the characteristics of simple structure, convenient operation, economical and practical.

Detailed ways

The structural principle and working principle of the present invention will be further described in detail below with reference to the accompanying drawings.

1, 2, 3, and 4, a washing machine pulsator includes a pulsator body 1, and three roller bases 2 are provided on the pulsator body 1; and a rotatable washing roller 3 is provided on the top of each roller base 2 , a circular groove is opened near the center of the pulsator body 1, and a triangular groove is opened near the edge of the pulsator body 1.

The rotatable washing roller 3 is a triangular body, and a washing rib of different structure and material is installed on the three sides of the triangular body to adapt to different types of laundry. Plastic rib, rubber rib and rib with brush on the surface. The hard plastic rib is used to wash the general laundry; the rubber rib is used to wash the laundry with hard objects such as metal, which can prevent the rib and the laundry from rigid collision and cause damage and reduce washing noise; Ribs with soft brush for stubborn stains.

One end of the three roller bases 2 points to the center of the pulsator body 1, the other end of the three roller bases 2 points to the outer edge of the pulsator body 1; the two roller bases 2 point to one of the ends of the center of the pulsator body 1. The included angle between them is 120°.

The end of the rotatable washing roller 3 that points to the center of the pulsator body 1 is connected to one end of the circular shaft 4; the other end of the circular shaft 4 is installed in the circular groove of the roller base 2 near the center of the pulsator body 1 Inside.

The circular shaft 4 is sleeved with a spring 5; the spring 5 is used to reset the rotatable washing roller 3 after changing the washing rib.

One end of the rotatable washing roller 3 pointing toward the outer edge of the pulsator body 1 is fixedly connected to one end of the triangular shaft 6 , and the other end of the triangular shaft 6 is set in a triangular groove at the outer edge of the pulsator body 1 . Before each rotation of the washing rib, push the rotatable washing roller 3 to the center of the pulsator body 1, so that the triangular shaft 6 is separated from the triangular groove, and then the rotatable washing roller 3 can be rotated to switch the washing rib; Rotate 120 degrees to insert the triangular groove, which ensures the accurate switching of the washing ribs on three sides. The triangular shaped shaft cooperates with the triangular groove to lock the rotatable washing roller 3, which ensures that the rotatable washing roller 3 does not rotate during the washing process.

The working principle of the present invention is:

The rotatable washing roller is equipped with three kinds of ribs of different materials and structures to adapt to different kinds of washed objects. The three kinds of ribs are hard plastic ribs, rubber ribs and ribs with brushes on the surface. The hard plastic rib is used to wash the general laundry; the rubber rib is used to wash the laundry with hard objects such as metal, which can prevent the rib and the laundry from rigid collision and cause damage and reduce washing noise; Ribs with soft brush for stubborn stains.

Before each rotation of the washing rib, push the rotatable washing roller to the center of the pulsator body to make the triangular shaft out of the triangular groove, and then turn the rotatable washing roller to switch the washing rib. The triangular shaft can be inserted into the triangular groove every time it rotates 120 degrees, which ensures the accurate switching of the three-sided washing rib. Since the other end is equipped with a spring, it can automatically reset after switching. The triangular shape of the shaft and the groove can lock the rotatable washing roller to ensure that the rotatable washing roller does not rotate during the washing process.
