Description

Device for preventing water dispersion in washing machine

The present invention relates to a fully automatic washing machine, and more particularly, to a washing machine provided with a shield for preventing scattering of water installed in an auto balancer in order to prevent the washing water that is permeated during permeation laundering and scattering. will be.

In general, the automatic washing machine is a product that removes contaminants such as clothes and bedding by using friction and impact of water flow due to emulsification of detergent and rotation of the washing blade. Automatically set the method, watering up to the appropriate level according to the amount and type of laundry, and washing under the control of the controller.

1 is a cross-sectional view of a conventional permeable washing machine. Referring to this, the permeable washing machine includes a main body 1 having a large appearance, an outer tub 2 fixed inside the main body 1, and an inside of the outer tub 2; Inner tub (3) rotatably installed on the surface and provided with a plurality of dehydration holes on the surface, washing blade (4) integrally formed in the inner tub (3) and rotated together, and the outer tub (5) Tub cover 5 is fastened to the upper portion and the drive means 6 for transmitting a driving force to the inner tub (3).

The outer tub 2 has a cylindrical shape in which the upper part is opened, and serves to receive the washing water in the body 1.

In addition, the inner tub 3 is installed inside the outer tub 2 and can be selectively rotated in the forward and reverse directions.

The washing blade 4 is integrally installed at the lower portion of the inner tub 3 and rotates together with the inner tub 3.

In addition, the tub cover 5 is fastened to the upper portion of the tub 2 and serves to guide the water permeated during permeation to the inner tub 3 again.

In the washing machine configured as described above, the washing water flow during permeation washing will be described in detail.

In the conventional permeation washing machine, the washing blade 4 and the inner tub 3 are integrally formed, and the inner tub 3 and the washing blade 4 are configured to rotate at a high speed by the driving means 6.

The wash water in the inner tub 3 separates the contaminants attached to the laundry material from the laundry while passing through the laundry by the centrifugal force formed by the high speed rotation of the inner tub 3.

Then, the wash water that has passed through the laundry passes through the dehydration hole (3a) formed in the inner tub (3) to move to the outer tub (2).

In addition, the washing water introduced into the outer tub 2 rises along the wall surface of the outer tub 2 by centrifugal force.

At this time, the dehydration hole (3a) is formed on the side wall of the inner tub (3) so that the wash water in the inner tub (3) can exit the dehydration hole (3a) to move to the outer tub (2).

On the other hand, the tub cover (5) is installed on the upper portion of the tub 2, the raised washing water is no longer raised and collides with the tub cover (5).

Washing water impinged on the tub cover (5) is to repeat the process of being re-introduced into the inner tub (3) to perform the washing.

That is, the washing water exiting from the inner tub 3 toward the outer tub 2 by the rotational force of the inner tub 3 rises on the inner circumferential surface of the outer tub 2, and the raised washing water is the tub cover 5. After colliding with the inner tub 3, the process flows back into the inner tub 3 again.

In the case of permeation laundering, washing is more effective than the conventional washing method because the washing water passes through the laundry and passes through the two steps of tapping the laundry by falling through the washing water.

However, as described above, when the washing water to be re-introduced into the inner tub (3) hits the floating laundry, it may not be completely re-introduced into the inner tub (3).

This situation occurs mainly when laundry is protruded upward from the tub cover 5 and washing is performed.

The case where the laundry protrudes above the tub cover 5 occurs when a large amount of laundry is put into the inner tub 3.

That is, when a large-capacity duvet lamp is put into the inner tub 3, the corner of the duvet or the like may protrude to the tub cover 5 position.

And the size is completely put into the inner tub (3), but in the case of a bed pillow that swells like a balloon when the wash water is supplied to float in the water similarly protrudes to the top of the tub cover (5).

In particular, in the case of the pillow for the bed as described above, due to the floating property in the water permeate washing through the outer tub (2) to be injected into the inner tub (3) is hit by a pillow is scattered to the outside.

That is, the washing water to be introduced into the inner tub (3) by the tub cover (5) during permeation washing flows down between the outer tub (2) and the main body (1).

When the leaked wash water falls out of the outer tub (2) and hits the bottom surface of the washing machine, it jumps up and flows into the electrical equipment provided at the lower portion of the outer tub (2). May occur.

In addition, in a country where a carpet culture is developed in which a washing machine is installed on a floor on which a carpet is placed, the carpet may be discarded by the leaked water.

In addition, when the electricity generated from the electric equipment of the washing machine is leaked by the wet carpet, serious problems may occur.

The present invention is to solve the above problems, the present invention is to prevent the laundry from floating more than the height of the auto balancer, so that the washing water re-introduced into the inner tub during permeation washing so as not to scatter far from the tub cover laundry The purpose is to prevent short-circuit and safety accidents caused by the inflow of wash water into the electrical equipment.
