Washing water induction structure of tub cover for permeation washing machine {WASHING MACHINE}

The present invention relates to a permeable washing machine, in particular, a plurality of first direction switching ribs formed on the bottom surface of the tub cover, the inner circumferential surface of the tub cover the washing water is changed by the first direction switching rib inside the washing tank Tub cover for permeable washing machine that can change the direction of the washing water flowing in the V-shape by the high speed rotation of the washing tank or the washing blade to the center direction of the washing tank by forming a downward direction rib for feeding downward to the laundry. It relates to a washing water induction structure of.

The conventional permeable washing machine rotates the washing tank and the washing vanes at high speed to make the water flow in the washing tank V-type, and the centrifugal force washes the contaminants in the laundry while passing through the laundry, and exits to the dehydration hole formed on the side of the washing tank. .

Then, the washing water discharged to the dehydration hole is raised through the wall surface of the washing tub, and the washing and rinsing strokes are repeated while being re-introduced into the washing tub.

However, the conventional permeation washing machine as described above does not circulate because the washing water rising on the wall surface of the washing tub continuously rotates along the circumference of the washing tub, so that the washing water is reduced and the washing water is reduced so that the circulation of the washing water for permeation washing is reduced. Had a problem that does not work smoothly.

In addition, a lot of washing water flows to the surface of the tub cover by the strong water flow of the washing water to the upper side.

In particular, since the surface of the conventional tub cover is formed in a flat shape, when excessive washing water is scattered, only a part of the washing water is discharged to the drain hose through an overflow hole formed in the washing tank, and most of the washing water is washed out. It goes over the circumference and flows to the outer wall of the laundry outer tub.

Therefore, the washing water flows through the outer wall surface of the washing tub to the floor, causing insulation breakdown of the electrical equipment in the washing machine, and acting as a cause of failure.

In addition, when the wash water leaks outside of the washing machine, that is, indoors, the user may be in a dangerous situation in which an electric shock may occur.

In particular, when a strong water flow hits the tub cover, the noise is greatly generated and bubbles are generated.

The purpose of the present invention for solving and solving these conventional problems,

It provides the purpose of enabling permeation washing by changing the direction of the washing water flow rising in the V shape by the high speed rotation of the washing tank or the washing blade to the center direction of the washing tank and re-injecting it into the washing tank.

And, for another purpose of the present invention,

It also provides the purpose of minimizing the generation of water splashing, noise, bubbles caused by the washing water flow circulated in the V shape by the high speed rotation of the washing tank or washing blade.

In order to achieve the above objects, the present invention,

A plurality of first direction switching ribs are formed on the bottom surface of the tub cover, and the inner circumferential surface of the tub cover is configured to downwardly supply washing water whose direction is changed by the first direction switching rib to the laundry inside the washing tub. Forming the rib makes it possible to achieve the object of the present invention.
