Description

[Detailed description of the invention] This invention relates to a spin-rinse washing machine that transfers clothes after washing to a spin-drying tank, and rinses the clothes by repeatedly supplying water and spinning in this spin-sink tank.
This is an improved dehydration cap unit attached to the dehydration tank to prevent clothes put into the dehydration tank from flying out and to remove iron rust contained in water supplied to the dehydration tank.

Conventionally, the dewatering cap unit in this type of washing machine has a plurality of through holes 2, as shown in FIG.
0, a cap cover 23 that is removably attached to the dehydration cap 21 with a claw part 22, and a rust removal filter 24 that is inserted into the space between the dehydration cap 21 and the cap cover 23 when they are attached. has been done. However, in this conventional dehydration cap unit, water can pass through the gap between the outer periphery of the filter 24 and the inner side wall of the cap cover 23 and through the through holes that fit into the claws 22 of the cap cover 23 of the dehydration cap 21. Therefore, some water does not pass through the filter 24. As a result, the water entering the dehydration tank is not completely filtered, and there are cases where iron rust adheres to clothing.

The present invention improves the conventional incomplete filtration function and makes it more complete, thereby eliminating rust on clothing caused by water supplied into the dehydration tank.

The present invention will be explained below with reference to the drawings. In Fig. 1, 1 is an outer casing, 2 is a dewatering tank molded from synthetic resin and installed inside the outer casing 1, and a drain port 3 is provided at the bottom.
has. A drain hose 4 is connected to the drain port 3. Reference numeral 5 denotes a dehydration tank rotatably installed inside the dehydration receiving tank 2, and a dehydration motor 7 elastically supported at the bottom of the outer casing 1 via a suspension 6.
It is fixed through a seal portion 10 having cushioning properties via a coupling ring 8 and a shaft 9. A cover plate 11 placed and fixed on the dehydration receiving tank 2 at the upper part of the dehydration tank 5 has a through hole 11a in the center, and is provided with an inner lid 12 that can be opened and closed over the hole 11a. A water supply nozzle 13 is provided to supply water into the interior.

A dehydration cap unit is detachably attached to the upper part of the dehydration tank 5. Reference numeral 14 designates a dehydration cap constituting the dehydration cap unit, which has a knob 14a at the center of the upper surface, a circumferential rib 14b at the outer periphery of the upper surface, and a plurality of holes on the inner plane of the circumferential rib 14b. A through hole 14c is provided. Further, on the lower surface of this dehydration cap 14, a circumferential rib 1 is provided.
A circumferential rib 14d having approximately the same diameter as the circumferential rib 4b and a presser rib 14e are provided inside the circumferential rib 14d. Reference numeral 15 designates a dish-shaped cap cover that is removably attached to the inside of the rib 14d with claws 15a, and has a plurality of through holes 15b provided in its flat surface. Further, reference numeral 16 denotes a filter having a filtration function, which is placed in the space created when the cap cover 15 is attached to the dehydration cap 14. At this time, the outer periphery of the filter 15 is held between a presser rib 14e on the lower surface of the dehydration cap 14 and a presser rib 15c provided on the inner surface of the cap cover 15 opposing thereto. Further, the claw hole for fitting the dehydration cap 14 and the cap cover 15 is formed by the presser rib 14 on the lower surface of the dehydration cap 14.
Since it is provided on the circumferential rib 14d provided on the outside of the dehydration cap 14, the circumferential rib 14 of the dehydration cap 14
The structure is such that all the water supplied in b passes through the filter 16 and falls into the dehydration tank 5.

In the washing machine having the above configuration, the clothes that have been washed in a separate washing tank are transferred to the dehydration tank 5, where water is supplied from the water supply nozzle 13 and the subsequent dehydration is repeated, thereby dehydrating and rinsing the clothes. It is something that In this case, water is supplied from the water supply nozzle 13 into the circumferential rib 14b of the dewatering cap 14,
All of this passes through the filter 16 and is supplied into the dehydration tank 5.

As mentioned above, in this invention, when performing dehydration rinsing in the dehydration tank, all of the water supplied to the dehydration tank passes through the filter of the dehydration cap unit, so iron rust etc. contained in the water can be completely removed. , clothes in the dehydration tank will not be contaminated with iron rust, etc. This can be achieved with a simple construction of a presser rib that simply faces the position of the through hole of the dehydration cap, and the effect is extremely large.
