Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water supply device for a washing machine that moderates the flow rate of water discharged from a water supply valve and supplies it to a washing tub.

Conventionally, in this type of water supply device, the bottom plate of the operation box is integrally molded and depressed to form a water supply device having a water outlet facing above the washing tub. At the same time as arranging the members, a cover plate is adhesively fixed to the upper surface of the water supply device, and the outlet body of the water supply valve disposed in the operation box is inserted into the water supply device through the insertion port formed in the cover plate. This is the inserted configuration. However, with this conventional structure, the lid plate is glued to the top surface of the water dispenser, which makes assembly difficult, and due to poor adhesion or changes over time, the lid plate and water dispenser may leak from the adhesive point into the operation box. It also had the disadvantage of causing water leaks.

The present invention has been made in view of the above circumstances, and aims to provide a water supply device for a washing machine that can be assembled very easily by omitting adhesive connection points and does not cause water leakage from the water supply device. purpose.

The following is an example of the present invention shown in Figures 1 and 2.
This will be explained with reference to the figures. 1 is the outer box, 2 is the water tank,
3 is a rotating tank that serves as a washing tank and dehydration tank, 4 is an outer box 1
A cover member made of, for example, plastic is fixed to the upper surface of the machine, 5 is an opening for taking in and taking out laundry, and 6 is a lid for opening and closing this opening 5. Reference numeral 7 denotes an operation box integrally formed on the rear part of the cover member 4, and has an operation panel 8 slanted on the front side secured by screws. Reference numeral 9 denotes a water supply device in the form of a rectangular container with an open upper surface formed by integrally molding plastic into the bottom surface of the operation box 7, and a rotary tank 3 at the front end thereof.
A water outlet 9a facing upward is formed. Reference numeral 10 denotes a water supply electromagnetic valve (water supply valve) fixed to the rear plate part 7a of the operation box 7 with screws, and the inlet body 11 is connected to the rear plate part 7a.
An approximately L tube is connected to one end of the water supply hose 12 through the inlet body 11 and protrudes to the rear of the operation box 7.
A letter-shaped elbow 13 is connected via a cap nut 14. Reference numeral 15 denotes an outlet body of the water supply electromagnetic valve 10, which is directed downward and faces into the water supply device 9. Reference numeral 16 denotes a cover member made of plastic, for example, which is formed in the shape of a short rectangular cylinder with an open bottom and has an integral top plate 16a.An insertion hole 17 is formed in the center of the top plate 16a, and a water hole is formed in the circumferential side of the bottom end. Notch 1 as a substantially U-shaped outflow part for outflow
A plurality of 6b are formed at predetermined intervals.
Before attaching the water supply electromagnetic valve 10 to the back plate 7a, the outlet body 15 is fitted into the insertion hole 17 of the cover member 16, and the water flow relaxation member 18 made of open cell material such as sponge is inserted into the cover member 16. After that, the water supply solenoid valve 10 is fixed to the back plate part 7a, and the cover member 16 is inserted into the water supply device 9 by the water supply solenoid valve 10.
The water supply solenoid valve 10 is clamped and fixed between the inner bottom surface of the water supply solenoid valve 10 and the water supply device 9. In addition, the water flow mitigation member 18 is connected to the lower end of the outlet body 15 and the water supply device 9.
sandwiched between the top surfaces of In addition, water supply hose 1
The other end of 2 is connected to a water faucet or the like (not shown).

Now, when the water supply electromagnetic valve 10 is energized and opened during water supply, the water flowing out from the outlet body 15 has a reduced flow velocity when passing through the water flow moderating member 18, and passes through the notch 16b to the lower part of the cover member 16. The water flows out into the surroundings, flows inside the water supply device 9 toward the water outlet 9a, and is supplied into the rotating tank 3 from the water outlet 9a.

As described above, according to this embodiment, the cover member 16 in which the water flow mitigation member 18 is disposed is connected to the top plate 16.
The outlet body 15 of the solenoid valve 10 for water supply is fitted into the insertion hole 17, and the cover member 16 is connected to the solenoid valve 10 for water supply. Since the valve 10 and the inner bottom surface of the water supply device 9 are supported by being clamped and fixed, there is no need for a lid that is fixed by adhesive as in the conventional structure, and the water supply solenoid valve 10 can be mounted in the operation box. 7 completes the installation of the cover member 16 and the water flow mitigation member 18, making the assembly very simple. Further, the cover member 16 has a top plate 16a.
Since it is integrally molded into a short cylindrical shape with Since the flow rate of the water flowing out is sufficiently weakened, water will not splash in the water supply device 9, and electrical components installed in the operation box 7 will not leak.

In the above configuration, the cover member 16 is fixed to the inner bottom surface of the water supply device 9 exclusively by the water supply solenoid valve 10, but in order to securely fix the cover member 16, some screws are used. It is also possible to add other fixing means such as.

FIG. 3 shows another embodiment of the present invention, and only the parts different from FIG. 1 will be explained.
That is, the cover member 19 is formed by integrally molding plastic into a rectangular cylinder shape having an upper surface plate 19a integrally and having an open lower surface. Protrusion 20
The protrusion 20 is formed by integral molding and is used as a water flow relaxation member, and the same functions and effects as those of the previous embodiment can be obtained, and the number of parts is reduced, making assembly even easier. Note that 19b is a notch for water to flow out as an outflow portion formed at the lower end of the cover member 19, similar to the notch 16b in FIG.

As explained above, the present invention is very easy to assemble because there are no adhesive connection points, and the installation of the cover member and water flow mitigation member is completed by attaching the water supply valve. Therefore, it is possible to provide a water supply device for a washing machine that is suitable when the water supply device is formed integrally with the operation box.
