Description

[Detailed Description of the Invention] The present invention relates to a water supply device for a dehydration and rinsing device that exerts a rinsing effect through the dehydration rotation of a dehydration basket.

In recent two-tank washing machines, rather than washing in the washing tank and then rinsing, water is supplied into a spin-drying basket rotatably placed in the spin-drying tank, and rinsing is performed by rotating the spin-drying basket. This method has come to be widely used. In other words, after washing, the cloth is transferred to a dehydration tank and dehydrated, water is directly supplied into the dehydration basket, the water is absorbed by the cloth in the dehydration basket, and then dehydration is performed, and this cycle is repeated. Rinse quickly with less water.

The water supply structure in this type of dewatering and rinsing equipment is
As shown in the figure, a ring-shaped guide 2 is provided in a tank 1, a bottom part 4 of a cylindrical water supply nozzle 3 is inserted into this guide 2, and an upper surface 6 of the water supply nozzle 3 is inserted into a panel 5 above the guide 2. It was fixed in a sandwich shape.

However, such a system has a drawback that a gap is created between the bottom 4 of the water supply nozzle 3 and the guide 2, and water that is intended to be supplied flows out from this gap.

Recently, a nozzle as shown in Fig. 2 has been proposed as a substitute for the water supply nozzle. A groove 8 is provided at the rear of the dehydration receiver cover 7 attached to the upper opening of the dehydration tank.
The water flowing out from the water channel 10 at the bottom of the panel 9 is received by the groove 8, and the water is supplied into the dewatering basket using the groove 8 as a guide. There was a drawback that the water overflowed from the groove 8. Furthermore, since the groove 8 is integrated with the dehydration receiving cover 7 and the dehydration receiving cover 7 is pressed down by the panel 9, the dehydration receiving cover 7 cannot be opened or closed, and a handkerchief is placed between the dehydration tank and the dehydration basket. The problem was that when small items such as items were to fall, it was extremely difficult to retrieve them.

The present invention provides a water supply device that solves the above-mentioned problems in the conventional water supply structure.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 3 to 5. In the figure, 11 is an outer box of the washing machine, and 12 is a dehydration tank, which is housed in the outer box 11 together with a washing tank (not shown). Reference numeral 13 denotes a dehydration basket, which is rotatably arranged inside the dehydration tank 12. 14 is an operation panel equipped with a dehydration timer 15 and the like, and 16 is a dehydration receiving cover that covers the periphery of the upper opening of the dehydration tank 12 and has a cloth input port in the center.

An electromagnetic water supply valve 17 is located on the left side of the operation panel 14.
is provided, and supplies water in conjunction with the dehydration timer 15.
The water is supplied to the water supply nozzle 1 via the water injection hose 18.
9 into the dehydration basket 13. The water supply nozzle 19 is provided with a guide hole 20 that serves as a guide to indicate the most appropriate amount of water to be poured even during rinsing work.If you adjust the water supply amount by looking at the water coming out of this guide hole 20, you can avoid wasting water. You can perform rinsing work effectively without using it.

A pair of substantially L-shaped claws 21 with bent ends facing each other is provided on the back surface of the dehydration receiving cover 16, and a substantially U-shaped rib 22 is formed protruding from the top surface of the water supply nozzle 19. It has been done. A pair of claws 21 engage and hold both sides of the water supply nozzle 19, and a rib 22 abuts against the back surface of the dehydration receiving cover 16.
This restricts the vertical and horizontal movement of the water supply nozzle 19, and by attaching the pawls 21 to stepped portions 23 provided on both sides of the water supply nozzle 19, the back and forth movement of the water supply nozzle 19 is restricted. do.

Further, the rib 24 on the upper surface of the water supply nozzle 19 works together with the dewatering receiving cover 16 to securely fix the water supply nozzle.

Fixing part 2 consisting of the rear end side of the dehydration receiving cover 16
5 is clamped and fixed between the operation panel 14 and the top surface of the dehydration tank 12, and a hinge part 26 is provided between this fixing part 25 and the cloth input port of the dehydration receiving cover 16. The receiving cover 16 can be opened and closed from the front side. The claw 21 is formed on the fixing part 25, and the fixing part 2
A rib 22 is in contact with the back surface of 5.

In the above configuration, the water supply nozzle 16 can be reliably positioned by the dehydration receiver cover 16, and the water supply nozzle 19 is unlikely to vibrate due to vibrations during dehydration and washing, and the reference hole 2
The water coming out of 0 is in a stable state.

Further, as shown in FIG. 4, the water supply nozzle 19 is supported by a claw 21 provided on a fixed part 25, and the dehydration receiving cover 16 is fixed by its hinge part 26 regardless of the water supply nozzle 19. It can be freely opened and closed in the directions of arrows a and b.

Further, as shown in FIG. 5, the water supply nozzle 19 can be assembled by inserting and fitting it from the rear of the dewatering receiving cover 16, and the assembly work is easy.
Good service. Further, since the water injection hose 18 between the electromagnetic water supply valve 17 and the water supply nozzle 19 is used as a water passage, there is no fear of water leakage.

As is clear from the above explanation, according to the present invention,
The water supply nozzle of the dewatering and rinsing device is easy to install and has good serviceability, and there is no need to worry about water leakage.
Furthermore, there are effects such as less vibration occurring when the dewatering basket is rotated and no hindrance to opening and closing of the dewatering tray cover.
