Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a washing machine for both dehydration and dehydration, and more particularly to a washing machine for dehydration and washing equipped with a dehydration and washing tub in a shape that improves washing performance during washing.

[Background of the invention]

In general, this type of dehydrating and washing machine is
It had a shape with the same waveform as in Japanese Patent Publication No. 7-37357. This configuration has the disadvantage that the washing effect that occurs when the laundry is rotated along the wall of the tub cannot be sufficiently obtained.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a washing and dehydrating tub for improving washing performance while maintaining other performance such as fabric damage and unevenness in a washing machine.

[Summary of the invention]

In the dehydration and oil washing tank with a protruding part facing the center,
Rather than making the height of the protrusion the same height.

The present invention focuses on the fact that the cleaning effect is further enhanced by providing the protrusion 5' with a high height.

[Embodiments of the invention]

1 person is the outer frame of the dehydrating washing machine (hereinafter referred to as the washing machine), 1
9 is an outer tank supported within this outer frame IA.

22 was rotatably supported within this outer tank 19. This is a dehydration/washing tub (hereinafter referred to as a washing tub).

1 is a dial for operating the washing machine, and 2 is a control unit, both of which are disposed on the outer frame IA, and the outer frame 1 is provided with legs 1o that support the washing machine. . Reference numeral 3 relates to a cover for the outer tank 19, and 4 relates to a water overflow device for overflowing the water in the outer tank 19 from the upper side wall of the outer tank 19 to the outside during rinsing. It is an overflow pipe.

As clearly shown in FIG. 2, the protruding part 5' formed on the washing tub 22 is a large protruding part, and the number 17 (#16) is a dewatering hole.

The side periphery itself is made to protrude in an arc shape toward the center so as to form a protrusion extending in the vertical direction. Further, 6 is a blade provided in the center of the washing tub 22 which rotates the cloth and water to be washed, and 7 is a shaft that drives the blade 6, and 8 is a vertical axis specific to washing. and a drain valve 12 provided at the bottom of the outer tank 19 and operated by an electromagnet or the like at the end of washing and rinsing.
This drain pipe discharges water from the bottom of the outer tank 19 to the outside via the drain hose 10 when opened.

These form a drainage device that drains water in the outer tank 19 from the bottom thereof. Also.

13 is the bottom part of the outer wall of the outer tank 19 (C provided washing,
A clutch 14 for switching dewatering transfers the power of the motor 15 to the washing tub 22 or the impeller 6 via the clutch 13.
These belts rotate the blades 6 during washing and rotate the washing tub 22 during spin-drying. This forms a drive device fixed to the outer wall of the outer tank 19. A hanging rod 18 elastically supports the outer tank 19 within the outer frame IA.

In the above configuration Q, during washing, the motor 15 rotates, the blades 6 rotate via the belt 14 and the clutch 13,
Rotates the laundry to create a cleaning action.

The water flow caused by the impeller 6 is shown in Figure 3, as follows: ■ rotating water flow, ■
Water and sewage flows are generated. Also, at this time, a water flow (2) directed toward the center is generated by the large protrusion 5' on the inner wall of the washing tub, and the laundry is easily caught in the upper and lower water flow (2). The cleaning performance is improved by moving it to the bottom large blade part. Further, the cleaning effect due to the washboard effect of the protrusion 5 of the washing tub 22 is further improved by the large protrusion 5'IC.

By providing the large protrusion 5' as described above.

A water current flows towards the center. This has the effect of promoting the changing of the top and bottom of the cloth, and also improving the washboard effect of the protrusion of the washing tub 22 and improving the cleaning rate.

In addition, by providing a plurality of large protrusions 5' in the washing tub 22 at equal intervals, the rotation of the blade 6 and the shifting of the fabric (which occurs when the fabric becomes lumpy) caused by the large protrusions 5' can be uniformly prevented. , and can prevent abnormal vibrations during dehydration.

〔Effect of the invention〕

According to the present invention, on the protrusion on the inner wall of the washing machine 22.

A simple and inexpensive method of providing a large protrusion 5' generates water flow toward the center, improving the washboard effect and improving cleaning performance while maintaining other washing performance compared to conventional structures. can be done.
