Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a two-tank washing machine, and particularly to an improvement of a washing tank lid of a two-tank washing machine.

The washing tank lid of a conventional two-tub washing machine is made of styrene and is relatively rigid, so it does not deform much even when pressed from above.

When this washing tank lid is manufactured using polypropylene, the polypropylene material itself does not have much rigidity and is easily bent by pressure from the top surface.

An object of the present invention is to suppress the deflection of a washing tank lid made of polypropylene.

In the present invention, the washing lid is formed into a rectangular shape and made of polypropylene resin, and a downward facing peripheral wall is formed on the outer periphery, and a hook is integrally formed on this peripheral wall in a place adjacent to the dehydrating lid. , consisting of a horizontal root portion that comes into contact with the top of the dewatering tray cover, a middle portion that hangs down from the root portion, and an outer end portion that extends approximately horizontally from the middle portion,
On the bottom of the washing lid on the opposite side of the hook,
An inner wall rib is formed that runs almost parallel to the peripheral wall, and the rib that comes into contact with the upper edge of the washing tank on the opposite side of the dehydrated water receiving tank is formed to connect the inner wall rib and the peripheral wall. It is characterized by integrally forming a protrusion protruding downward from the ribs and slightly entering the washing tank from the upper end edge of the washing tank.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The washing machine body 1 has an outer frame 4 in which a tank body 7 is placed.
and a synthetic resin panel 6 on which a knob 5 is arranged. The tank body 7 is made of synthetic resin and includes a dehydrated water receiving tank in which the dehydrating tank 3 is placed, and a washing tank 2.

A water supply opening 8, into which a water supply hose is inserted, is provided at the center of the upper surface of the panel portion 6.

Furthermore, a washing tank lid 10 and a dehydration tank lid 11 made of synthetic resin are attached to the upper part of the metal outer frame 4 so as to be openable and closable.

A synthetic resin shelf 9 for storing small items is placed in contact with the upper surface of the panel portion 6.

In addition, inside the washing tank 2, there is an overflow filter device 1 in an overflow box which is a recess in the side wall.
2 is detachably attached. This overflow filter device 12 includes an overflow box cover 13.
and a partition plate 13 that is provided so as to be able to move vertically and integrally within this overflow box cover 13.
a, and an overflow strainer 14. A drainage strainer 15 is attached to the lower part of the overflow filter device 11. Further, a pulsator 16 is disposed at the bottom of the washing tank 2.

On the other hand, a synthetic resin dehydration receiving cover 17 having an opening is provided on the upper surface of the dehydration tank 3, and an inner lid 18 made of synthetic resin that can be opened and closed is attached to this dehydration receiving cover 17.

A synthetic resin towel rack 19 is attached to the front of the washing tank 2.

Next, the washing tank lid 10 will be explained.

The washing tank lid 10 is made of polypropylene resin and has a rectangular shape. Wash tank lid 1
A peripheral wall portion 21 is formed on the outer periphery of 0. The peripheral wall part has four wall parts 21a, 21b, 21c, 21
d. Wall portion 21b, wall portion 2
Inner wall ribs 22a, 22b are provided that run parallel to 1c. An auxiliary inner wall rib 23 is formed between the inner wall rib 22a and the wall portion 21b. The right end of the auxiliary inner wall rib 23 extends parallel to the wall portion 21c.

Four pairs of ribs 25 are formed to connect the auxiliary inner wall ribs 23 and the wall portion 21b. Auxiliary inner wall rib 2
One rib 26 is formed to connect the wall portion 21c to the wall portion 21c.

Rib 29 connecting inner wall rib 22b and wall portion 21c
is formed. The inner wall rib 22b has a rib 2
A protrusion 28 is integrally formed at a location corresponding to 9.

The peripheral wall portion 21, the inner wall ribs 22a and 22b, the auxiliary inner wall ribs 23, and the ribs 25, 26, and 29 are formed so as to hang down from the lower surface of the washing lid 10.

The protrusion 28 protrudes from the upper edge of the washing tank 2 so as to slightly enter into the washing tank 28. Further, the rib 29 is formed so as to come into contact with the upper edge of the washing tank 2.

A hook 27 is formed on the wall portion 21a of the peripheral wall portion 21. The hook 27 is for hooking the washing tank lid 10 onto the washing machine main body 1, as shown in FIG.

This hook 27 has a structure as shown in FIGS. 7, 8, and 9.

That is, the hook 27 is composed of a root portion 27a extending horizontally from the lower end of the wall portion 21a, an intermediate portion 27b hanging diagonally from the root portion 27a, and an outer end portion 27c extending approximately horizontally from the intermediate portion. be done. The reinforcing ribs 27d, 27d are connected to the wall portion 21a.
It is reinforced by connecting it to hook 27.

Now, when the washing tank lid 10 is placed over the washing tank 2, the ribs 29 come into contact with the upper edge of the washing tank 2. At the same time, the root portion 27a of the hook 27 comes into contact with the upper part of the dehydration receiving cover 27. In this way, the washing tank lid 10 is placed on top of the washing tank 2.

When the washing tank lid 10 is pushed from above, the center of the washing tank lid 10 is depressed and the whole body is bent into a curved shape.
At this time, the protruding portion 28 and the intermediate portion 27b of the hook 27 prevent the deflection from becoming extremely large.

That is, as the washing tank lid 1C is bent, the middle part 27b of the hook 27 is moved to the dehydration receiving cover 17.
At the same time, the protrusion 28 comes into contact with the inner surface of the upper edge of the washing tank 2. This contact prevents the washing tank lid 10 from further bending.

Since the washing tank lid 10 is made of polypropylene resin, it is easily bent, but as described above, the bending is suppressed, so that it does not bend excessively.

As described above, in the present invention, the washing lid has a rectangular shape and is made of polypropylene resin, and a downward facing peripheral wall is formed on the outer periphery, and a hook is integrated into this peripheral wall adjacent to the dehydrating lid. The hook is composed of a horizontal root part that comes into contact with the top of the dehydration receiving cover, a middle part that hangs down from this root part, and an outer end part that extends almost horizontally from this middle part. The lower surface of the washing lid on the opposite side is formed with an inner wall rib that runs almost parallel to the surrounding wall, and the rib that comes into contact with the upper edge of the washing tank on the opposite side of the dehydrated water receiving tank connects the inner wall rib and the surrounding wall. A two-tank washing machine characterized in that the inner wall rib is integrally formed with a protrusion near the rib that protrudes below the rib and enters a little into the washing tank from the upper edge of the washing tank. be.

According to this configuration, the following actions and effects can be expected.

(1) The middle part of the hook abuts on the dehydration receiver cover, and the protruding part of the inner wall rib abuts on the inside of the washing tank, preventing the washing tank lid from bending excessively.

(2) Since the protruding portion is provided on only a portion of the inner wall rib, there is no sink mark on the surface of the washing tank lid, and it is just for appearance.
