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 smoothly circulates the washing water for permeation washing as the washing water rising on the wall surface of the washing tub is continuously rotated along the circumferential surface of the washing tub and is not circulated or scattered and the washing water is reduced. Had a problem that could not be made.

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 be sprayed upward.

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,

The purpose of the present invention is to improve the performance of 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 be re-injected 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.

Referring to the operation of the present invention as described above is as follows.

First, when the laundry is put into the washing tub 802 coupled to the permeable washing machine 801 of FIG. 1 and the washing start button is pressed, water is supplied and the motor 805 starts driving.

In addition, the washing inner tub 802 and the washing blade 803 are driven at a high speed by the driving of the motor 105.

At this time, the wash water in the wash tub 802 is discharged to the wash tub 804 through the laundry holes of the wash tub 802 after passing through the laundry.

In addition, the washing water discharged to the washing tub 804 is moved upward by riding on the inner wall surface of the washing tub 804 by the high speed rotational force of the washing tub 802.

In addition, the washing water rising to the upper side of the washing tub 804 is re-supplied into the washing tub 802 by the guide of the tub cover 811.

As described above, the permeable washing machine 801 of the present invention can perform permeation washing while circulating the washing water in the V-shape.

At this time, the washing water raised upward along the wall surface of the washing tub 804 by the high-speed rotation of the washing tub 802 is in contact with the bottom surface of the tub cover 811, the washing water tub cover 811 Under the direction of the first direction switching rib 812 formed as shown in the first embodiment of FIG.

However, in the third embodiment, since the wash water falls to the center or across the center of the washing tub 802 while drawing a parabola, in terms of efficiency, the washing water is vertically washed by the lower induction rib 813. The drop in 802 is lower than in the first and second embodiments.

However, since the third embodiment can achieve the object of the present invention sufficiently, it will be included in the scope of the present invention.

Meanwhile, in the fourth exemplary embodiment of FIG. 13 of the present invention, the plurality of second direction switching ribs are symmetrical with the plurality of first direction switching ribs 812 formed on the bottom surface of the tub cover 811.

By forming the 822, the direction of the washing water rising on the wall surface of the washing tub 804 by the bidirectional rotation of the washing tub 802 or the washing blade 803 can be changed to the center direction of the washing tub 802. It was made.

In addition, in Fig. 12 of the present invention, instead of the first buffering rib 815 of the second embodiment, the lowering guide rib

By forming the first through hole 816 in the 813, the washing water passing through the end of the first direction switching rib 812 is supplied to the washing tub 132 while passing through the first through hole 816 without resistance. It will be able to minimize the scattering of the wash water.

In addition, the wash water passing through the end of the second direction switching rib 822 is symmetrically lower than the first through part 816 of the downward direction rib 813 so that the washing water can be supplied to the washing tub 802 without resistance. By forming a second through-hole 826 in the directional induction rib 813, the washing water diverted by the second directional switching rib 822 collides with the downward guiding rib 813, and thus the washing water is scattered. Can be minimized.

Further, in the fifth embodiment of Fig. 15 of the present invention, the second buffering ribs 825 having lower heights are provided between the end portions of the second turning ribs 822 and the downwardly directed ribs 813. The washing water moving along the second direction switching rib 822 is weakened by the force of the washing water by colliding with the second buffering ribs 825 before hitting the lower induction rib 813. In addition, when the wash water collides with the lower induction rib 813, the direction is changed, thereby minimizing the generation of water splashes, noise, and bubbles due to the circulating water.

In addition, the height of the second buffer rib 825 is also formed to be lower than the height of the second direction switching rib 822 and the downward direction rib 813.
