And, during the rinsing stroke clean water is supplied into the washing tank (10).

The reservoir 8 is formed in a cylindrical shape with an open upper portion, and a cover 9 is installed at an upper end thereof to prevent upward detachment of the laundry (W), and a drain hose for draining the laundry liquid contained at one lower portion thereof. 9a and the drain valve 9b are arrange | positioned.

The washing tank 10 has a cylindrical shape with an open top, and is equipped with a balance 11 at the top thereof to maintain the equilibrium of the washing tank 10 to prevent vibration, and to have turbulent flow in the washing liquid rotated along an inner circumferential surface thereof. Embossing 20 for generating and diffusing protrudes.

3 is an enlarged perspective view of the washing tank according to the present invention, Figure 4 is an enlarged front view of the washing tank embossing according to the present invention, Figure 5 is an enlarged cross-sectional view of the washing tank embossing according to the present invention.

As shown in FIGS. 3 to 5, the embossing 20 protrudes in and outward of the washing tub 10 to generate and diffuse turbulent flow of the washing liquid that is rotated along the inner circumferential surface of the washing tub 10.

That is, the embossing 20, as shown in Figures 3 to 5, is formed with a ridge 22 which is raised in the inner direction (C) of the washing tank 10, in the center of the ridge 22 It consists of a double structure in which the recessed part 30 recessed in the outer direction D of the washing tank 10 is formed.

Here, the ridge 22 is protruded in a hexagonal shape, as shown in Figure 4, the portion of the washing solution to be hit by the side of the ridge 22, the upper and lower directions of the ridge 22 (A, B), and as shown in FIG. 5, it is formed to protrude gradually toward the center, and guides the rest of the washing liquid hit by the side of the ridge 22 toward the inner direction C of the washing tank 10. .

In addition, the depression 30 is formed in a circular shape, and the portion 31 bent at the ridge 22 is formed to be not angularly smooth, so that the vortex (or vortex) washes over the ridge 22. Vortex flow) and increase turbulence.

On the other hand, the embossing 20 is formed in the side position of the hand 10a, the depression 30 is formed with a separate hand 38 in the center or eccentric position.

Looking at the operation of the present invention configured as described above are as follows.

First, when the user puts the laundry in the washing tank 10 and operates the washing machine, the washing liquid is supplied into the washing tank 10 so that the water rises up to a predetermined height in the storage tank 8 and the washing tank 10, and The motor 14 and the clutch 16 are operated to wash while rotating the pulsator 12 and the washing tank 10.

At this time, the washing liquid is rotated inside the washing tank 10 to remove the contaminants on the laundry by the action of the detergent contained in the washing liquid.

On the other hand, the washing liquid is guided along the inner circumferential surface of the washing tank 10 of the washing liquid is turbulent is formed and diffused while passing through the periphery of the embossing 20 to increase the washing power of the laundry, around the embossing 20 The laundry turbulence formation process is described in more detail as follows.

Some of the washing liquid rotated along the inner circumferential surface of the washing tank 10 after hitting the side of the ridge 22, as shown in Figure 4, the up and down directions (A, B) of the ridge 22 Splashed and mixed with the washing liquid passing through the upper and lower sides of the ridge 22 to form turbulence on the upper and lower sides of the ridge 22.

In addition, some of the washing liquid rotates along the inner circumferential surface of the washing tank 10 is splashed in the inner direction (C) of the washing tank 10, as shown in Figure 5, and rotated inwardly of the ridge 22 The turbulence is formed inside the ridge 22 while being mixed with the washing liquid.

Then, the washing liquid guided along the inner surface of the ridge 22 does not flow along the bent portion 31 of the depression 30, peeling and reattachment, as shown in FIG. Vortex is generated in a portion E of the depression 30 that is rapidly recessed. The peeling and reattachment of the washing liquid reduces the dynamic pressure of the washing liquid, and the reduced dynamic pressure is converted into turbulent energy, thereby increasing the momentum, heat energy, and mass transfer of contaminants and water of the laundry. The cleaning ability is improved.

Finally, the washing solution rotated along the depression 30 hits the bending portion 31 of the depression 30 and is splashed in the inner direction C of the washing tub 10, and the ridge 22 The turbulence is formed inside the ridge 22 while being mixed with the washing liquid which has been rotated inward.

On the other hand, after a predetermined time elapses after the washing as described above, the motor 14 and the clutch 16 stops the operation, the drain valve 9b provided in the lower portion of the reservoir 8 is opened while the reservoir 8 The water inside is drained to the outside through the drain hose 9b.

When the drainage is completed as described above, the water is supplied to the washing tank 10 again to rise to a certain height of the washing tank 10 and the water storage tank 8, and then the rinsing operation is performed. In this case, the embossing 20 forms turbulent current in the washing liquid flowing along the inner circumferential surface of the washing tank 10 as in the washing operation so that the bubbles in the laundry (W) can be quickly separated.

When the washing and rinsing operation is completed as described above, only the washing tank 10 is rotated at a high speed so that a dehydration operation for removing water contained in the laundry (W) is performed. The washing tank 10 has a high speed. The water contained in the laundry (W) rotated by the water tank 22 is more rapidly through the water hole 38 formed in the embossing 20 by the centrifugal force, and the water hole 10a formed in a portion other than the embossing 20. After being moved to, it is drained to the outside through the drain valve 9b and the drain hose 9a.

The washing tank embossing of the washing machine according to the present invention constituted as described above forms a turbulence around the ridge raised in the inner direction of the washing tank, and the recessed portion recessed in the outer direction of the washing tank in the center of the ridge generates vortex. There is an advantage of improving the washing ability of the laundry by increasing the momentum, heat energy, mass transfer of pollutants and water of the laundry.

In addition, since the recess of the embossing is made of water in the center or eccentric position, the washing tank can have more water, thereby reducing the dehydration time and improving the dewatering performance.
