Description

Structure for preventing water dispersion in washing machine

The present invention relates to a fully automatic washing machine, and more particularly, when the washing machine is driven by permeation washing, the laundry penetrates the laundry and escapes to the outside of the inner tub. It relates to a washing machine for preventing the phenomenon flowing into.

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 characteristic of floating in water, the washing water that is injected into the inner tub (3) during the permeate washing is scattered to the outside by hitting the pillow.

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 shielded to prevent the scattered wash water from flowing into the electrical equipment when the wash water flowed back into the upper tub cover when the laundry was re-introduced into the inner tub during permeation washing By doing so, the purpose of the present invention is to prevent short-circuits or safety accidents caused by the inflow of wash water into electrical equipment.

Hereinafter, with reference to FIGS. 4A and 4B and FIGS. 5A and 5B, a guide G for preventing permeation washing water from colliding with the laundry and scattering when the laundry is suspended near the tub cover 50 will be described.

4A illustrates a tub cover 50 having a guide G formed therein to prevent the washing water from scattering. 4B is a cross-sectional view taken along the line A-A of FIG. 4A.

As shown in FIGS. 4A and 4B, the guide G extends from the lower guide rib 53 forming the inner circumference of the tub cover 50 toward the center of the tub cover.

The guide G is installed to be inclined upwardly from an upper end of the lower induction rib 53.

In addition, at the end of the guide (G) is formed a guide rib (Gr) formed to extend vertically downward from the inner end in order to reflow the wash water scattered by the laundry into the inner tub (30).

In addition, despite the installation of the guide G on the inner and outer sides of the tub cover 50, if the wash water is scattered to the tub cover 50, the wash water falls out of the tub cover 50. Shielding ribs 5a and 5b are formed to prevent exiting.

At this time, the shielding ribs 5a and 5b are spaced apart in the radial direction and formed to have an annular shape.

In addition, at least one drain hole 60 is formed in the region between the shielding ribs 5a and 5b of the tub cover to allow the washing water introduced into the tub cover upper surface to flow back into the inner tub. .

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

First, the laundry is put into the interior of the inner tub 30 constituting the permeable washing machine of FIG. 2 and the washing start button is pressed to start washing.

When the washing machine starts to operate, washing water flows into the inner tub 30, and at the same time, the driving means B starts driving.

In addition, the inner tub 30 and the washing blade 40 are simultaneously rotated at a high speed by the driving means B. FIG.

At this time, the wash water in the inner tub 30 passes through the laundry and is discharged to the outer tub 20 through the washing holes of the inner tub 30.

And the wash water discharged to the outer tub 20 ascends to the upper side on the inner wall surface of the outer tub 20 by the centrifugal force by the high-speed rotation of the inner tub 30 continues.

In addition, the washing water rising to the upper side of the tub 20 is re-supplied into the inner tub 30 by the guide of the tub cover 50. As described above, the permeable washing machine of the present invention may perform permeation washing while circulating washing water forming a 'V' shape.

During the permeation washing that proceeds as described above, the wash water re-introduced through the tub cover 50 into the inner tub 30 collides with the laundry projecting to the upper portion of the tub cover 50 and is scattered in all directions.

And some of the washing water scattered in all directions will have a tendency to move toward the tub cover 50.

However, the wash water intended to move to the top of the tub cover 50 impinges on the guide rib Gr and no longer moves to the outside of the tub cover 50.

In addition, the washing water collided with the guide rib Gr falls into the inner tub 30 and is collected in the inner tub 30. In addition, the wash water collected by the inner tub 30 repeatedly passes through the laundry by permeation washing and ascends the outer tub 20.

And, despite the installation of the guide (G), even if the washing water is scattered to the upper surface of the tub cover 50, the shielding rib (5a) in a direction perpendicular to the upper surface of the tub cover on the inner and outer sides of the upper surface of the tub cover (50) ) 5b is formed, and the shielding ribs 5a and 5b prevent the wash water from escaping out of the tub cover 50.

On the other hand, the wash water that collects in the area between the shield ribs 5a and 5b on the upper surface of the tub cover 50 is introduced into the inner tub 30 again through the drain hole 60 formed on the upper surface of the tub cover 50. .

Hereinafter, another embodiment of the guide G will be described with reference to FIGS. 5A and 5B.

Figure 5a is a longitudinal sectional view showing another embodiment of the guide (G) to prevent the scattering of the wash water, Figure 5b is a cross-sectional view B-B of Figure 5a.

5A and 5B, in the present embodiment, the guide G extends from the inner circumferential end of the tub cover 50 toward the center of the inner tub 30 and washes water scattered by the laundry. It is curved toward the downward direction for easy reflow into the inner tub 30.

Therefore, when the guide G extends to the center of the inner tub 30, the floating laundry is in contact with the end of the guide G of the tub cover 50, and thus, between the laundry and the lower guide rib 53. There is a constant space formed.

Therefore, the wash water guided toward the laundry inside the inner tub 30 by the lower induction rib 53 prevents the washing water from being scattered in contact with the end of the guide G. Instead of being scattered, it flows into the inner tub 30 through a space formed between the laundry and the lower induction rib 53.

In addition, in the present embodiment, even if the washing water is scattered to the upper surface of the tub cover 50, despite the installation of the guide (G) on the inside and outside of the upper surface of the tub cover 50, the washing water is the tub cover 50 Shielding ribs 5a and 5b are formed to prevent them from escaping outward.

At this time, the shielding ribs 5a and 5b are spaced apart in the radial direction and formed to have an annular shape.

In addition, at least one drain hole 60 is formed in the region between the shielding ribs 5a and 5b of the tub cover to allow the washing water introduced into the tub cover upper surface to flow back into the inner tub. The operation is the same as in the above-described embodiment.

This invention is within the scope of the basic technical idea, many modifications are possible to those of ordinary skill in the art.

According to the present invention as described above, by the guide installed on the inner cover of the tub cover of the washing machine has the advantage that can prevent the washing water introduced into the inner tub during the washing impinge on the laundry to be scattered.
