Abstract

PROBLEM TO BE SOLVED: To improve washing efficiency by providing a washing means for executing washing by means of vertically moving washing water while executing a reciprocation in a vertical direction with the rotation of a pulsator and also hitting the wash. SOLUTION: When the pulsator is rotated at the time of a washing operation, washing water at the lower side of the pulsator is made to flow by providing multiple wings 134a in a washing shaft 134 which is integrated with the pulsator so as to be injected upwards from multiple injecting ports 125 which are formed on the upper surface of the pulsator. Elevating/lowering washing members 140 which are moved with the reciprocation in the vertical direction so as to hit the wash and to execute washing are provided in the periphery of the pulsator 120. That is, a cam-shaped bending surface is circularly formed on the upper surface of a peripheral part which is formed in the one-step lower position of the base part of the pulsator. Then, the wash is hit by ring-shaped washing plate 147 against an elastive member 160 with the pin 141 of the elevating/lowering washing members 140, which is provided with a roller in a lower end part, by the rotary movement of the bending surface so that washing efficiency is improved.

The lifting / lowering washing member 140 includes a roller 141.
And a pin 144 and a washing plate 147.

When the pulsator 120 rotates, the roller 141 reciprocates in the vertical direction due to a difference in height of the bent surface 123 when the pulsator 120 rotates. That is, the roller 141 is connected to the curved surface 12.
It rolls along 3 and reciprocates vertically and is spherical.

The lower end 144a of the pin 144 is connected to the roller 141, and the upper end 144b is connected to the support plate 15.
Extends above zero. The roller 141 is connected to the pin 1
The pin 144 is connected to the lower end portion 144a of the pin 144 so as to be rotatable 360 degrees with respect to 44, and rolls on the bent surface 123.

The ring-shaped washing plate 147 is
The pin 144 is coupled to the upper end 144b, and reciprocates vertically by the pin 144. The washing plate 147 moves the washing water vertically and strikes the laundry. Accordingly, the laundry is washed cleanly, and the laundry does not move to the upper side of the center of the pulsator 120. Washing board 1
A large number of projections 147a are formed on 47 to increase the contact area between the laundry and the washing plate 147.

The elastic member 160 is mounted on the support plate 150
Is installed between the upper surface of the washing plate 147 and the bottom surface of the washing plate 147 to return the elevating washing member 140 to the initial state. More specifically, the elastic member 160 may include a coil spring wound around the pin 144. One end 161 of the coil spring 160 is fixed to the support plate 150 and the other end is fixed to the washing plate 147, respectively.
40 is raised and lowered easily.

A bellows 165 wraps around the elastic member 160 to prevent foreign matter and laundry from entering the elastic member 160.

When the position of the elevating washing member 140 is higher than the position of the pulsator 120, the elevating washing member 140 may obstruct the flow of the washing water generated by the rotation of the pulsator 120. In order to prevent this, the upper surface portion 122a of the wing 122 of the pulsator 120
(See FIG. 3) is located higher than the upper surface of the washing plate 147.

FIGS. 6 and 7 are views showing the operating state of the elevating washing member according to one embodiment of the present invention, which will be described. When the washing shaft 134 rotates in the state of FIG.
The wings 134 a cause the washing water that has flowed into the space 115 to be ejected to the upper side of the pulsator 120 through the ejection holes 125. Further, the roller 141 in contact with the bending surface 123
The washing plate 147 moves up and down as shown in FIG. Accordingly, the washing water spouted through the spouting holes 125 strikes the laundry, and the washing plate 147 strikes the laundry and moves the washing water vertically. After the elevating washing member 140 is raised as shown in FIG.
The elevating washing member 140 is lowered as shown in FIG. 6 by the elastic force of the elastic member 160 and its own weight.

[0032]
