[0002]

2. Description of the Related Art Conventionally, a push-wash type dewatering washing machine is known from JP-A-58-138485. This push-wash type dehydration washing machine is shown in FIG. In FIG. 3, the push-wash dewatering washing machine includes a case 31, an outer husk 32 provided in the case 31, an inner tub 33 rotatably provided inside the outer husk 32, and an inner tub 33. Is provided on the bottom of the press washing plate 35 having a plurality of through holes 34 on the surface, and between the case 31 and the outer bowl 32, the push washing plate 35 is moved at a constant stroke. Lifting mechanism A for moving up and down with, and the middle tub 33 provided on the upper part of the middle tub 33.
And a lifting lid 40 that is lifted up and down.

[0003]

In a conventional push-wash dewatering washing machine, a case 31, an outer rice cake 32 provided in the case 31, and a rotatably provided inside the outer rice cake 32 are provided. A trough 33, a push-wash plate 35 that is provided at the bottom of the middle trough 33 so as to be able to move up and down, and has a plurality of through holes 34 formed in the surface, and is provided between the case 31 and the outer bowl 32. Since the raising / lowering mechanism A for raising / lowering the washing plate 35 with a constant stroke and the raising / lowering lid 40 provided on the upper part of the middle tub 33 and moved up and down inside the middle tub 33 are provided, the apparatus becomes bulky and By pushing up and down the push-wash plate 35 provided at the bottom of the trough 33 to be placed inside the case 31 with a constant stroke, the laundry in the trough 33 is pushed up in the trough 33 from the bottom to the top. Wash, that is, wash from bottom to top Because in a manner to perform the washing by pressing while the push-up, a problem that the laundry inside is not able to wash down the well laundry escapes of medium-tub 33 is there.

[0004]

According to a first aspect of the present invention, an outer tub for containing a liquid and a plurality of holes for dewatering are formed around the outer tub, and the inner tub is rotatably provided in the outer tub. A drive means provided on the outer tub for rotating the middle tub, a lid member provided on the upper part of the outer tub for closing the upper part of the outer tub, the outer tub and the lid. A vertical movement member provided between the lid member and the lid member for moving the lid member up and down with respect to the outer tub, and a plurality of holes for liquid inflow are formed on the surface to freely move in and out of the middle tub. And a push washing member that is arranged so as to be movable up and down, and that is provided on the lid member,
A vertical movement moving means for moving the push-washing member in the inside of the trough so that the push-washing member can move up and down, and the push-washing member is provided between the push-washing member and the up-down movement moving means. A push-wash type dewatering washing machine comprising: a cushioning member that softens the vertical movement of the push-washing member in the middle tub when the push-washing member moves up and down.

[0005]

According to the first aspect of the present invention, since the lid member is supported so as to be movable up and down and the push-wash member is supported via the cushioning member, the push-wash member can be flexibly moved up and down in the middle trough from above. Move to wash the laundry.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 denotes an outer tub of the washing machine whose upper part is opened. Inside the outer tub 1, a rotatable middle tub 2 is provided. A large number of holes 3 for dehydration are formed on the peripheral surface of the middle trough 2.
Has been drilled. The middle tub 2 is connected to a motor 4 provided at a lower portion of the outer tub 1 so as to be rotationally driven. Two columns 5 are erected near the periphery of the outer casing 1, and the columns 5 are provided so as to be vertically expandable and contractable. A lid member 6 is fixed to the upper portion of the column 5.
A hole 9 is formed in the center of the lid member 6. Lid member 6
A motor 7 is mounted on the upper part of the. A crank mechanism composed of a crank 10 and a connecting rod 11 is connected to an output shaft 8 of the motor 7. The link rod 11 is provided with a support rod 12 that is vertically movable. At the lower end of the support rod 12, there is provided a disc-shaped push washing member 15 having a large number of holes 14 for liquid inflow formed on the surface thereof. A part of the support rod 12 is pushed by the motor 7 when the push-wash member 15 moves up and down in the trough 2 via the crank mechanism, regardless of the amount of laundry in the trough 2. An elastic spring 16 is provided so that the washing member 15 presses the laundry. Reference numeral 17 is a flexible hose for injecting water into the outer tub 1, 18 is a pipe for draining water for rinsing and washing, 19 is a drain pipe, 20 is a base, and 21
Is a caster, and 22 is a locking tool for locking the column 5 in a stretched state.

[0007] Laundry and detergent are put in the middle tub 2.
By contracting the column 5, the lid member 6 is lowered to close the opening of the outer tub 1. Water is injected into the outer tub 1 through the injection pipe 17. The motor 7 is started and the output shaft 8 is rotationally driven. By rotating the output shaft 8 to vertically move the support rod 12 through the crank mechanism and vertically move the push-wash member 15 in the trough 3, the laundry in the trough 3 is pushed and washed. Then, when the laundry is pushed and washed, the water in the outer tub 1 is drained by the drain pipe 19, the motor 4 is started, the middle tub 2 is rotated, and the laundry is dehydrated.

Although the above-mentioned embodiment shows an example applied to a dehydration washing machine using water as a washing medium, the present invention can also be applied to a washing machine for dry cleaning using a dry cleaning liquid as a washing medium.

[0009]

EFFECT OF THE INVENTION In the present invention, since the lid member is supported so as to be vertically movable, it can be used by lowering the lid, and the device can be made small in size, and the push-washing member is inside the trough. It is arranged so that it moves up and down from above via the cushioning member, and since the push-wash member is moved up and down from above in the inside of the trough for washing, the laundry is flexibly pressed inside the trough. , Soap water is gradually sucked into and discharged from the laundry, and delicate wool fibers can be washed in a state similar to hand kneading without damaging the fabric.
