Description

[Detailed Description of the Invention] The present invention relates to a water supply switching device for a washing machine that switches the water supply to a washing tub and a dehydration tub by a pressing operation.

Conventionally, in a two-tub washing machine having a centrifugal spin-drying tank, the laundry washed in the washing tub is transferred to the spin-drying tank, the spin-drying operation is performed once, and then water is supplied to the spin-drying tank and the spin-drying operation is performed again. I was told to reduce the amount of water when rinsing in the next washing tub.
A so-called dewatering and rinsing method has been adopted, and as a result, there is a demand for a water supply switching structure that can easily switch the water supply to the washing tub and the water supply to the dehydration tub.

This invention provides a structure that allows easy and reliable switching of water supply to the washing tub and spin-drying tub.
Examples thereof will be described below.

In the figure, 1 is a panel stand placed and fixed on the upper part of the main body (not shown), which includes a laundry side water supply channel 2 which is a water supply channel to the washing tank, and a dewatering side water supply channel which is a water supply channel to the dewatering tank (not shown). It has a water conduit 3. 2a and 3a are water supply ports. In addition, 4 has a pipe part 5 to which a water supply hose is connected, and this pipe part 5 on the central upper surface part.
This is a water supply table having two fan-shaped through holes 6 formed by concentric arcs and facing each other, and is mounted on the panel stand 1 with screws or the like so as to straddle the washing side conduit 2 and the dewatering side conduit 3. Fixed position.

The water supply joint 7 has a connecting pipe 8 at the top, two claws 9 at opposing positions across the connecting pipe 8, and a discharge port 10 at the bottom, and is hollow inside with a vertical plate 11 with a cylindrical tip on the side of the body, through which the connecting pipe 8 and the discharge port 10 communicate. The water supply joint 7 is rotatably connected to the water supply stand 4 by the claws 9 and the connecting pipe 8.

Reference numeral 12 denotes an operation panel to which electrical components and the like are attached, and is placed and fixed on the panel stand 1. A double push button 13 is slidably provided on the front side of the operation panel 12, and a cutout hole 1 is provided at the end of the push button 13.
4 is formed.

A movable body 15 is attached to the cover 17 by rotatably supporting the shaft 16 with a bearing 18 of the cover 17, and includes a groove 19 that connects to the vertical plate 11 of the water supply joint 7;
It has a guide 20 that spreads laterally from the tip thereof, and a cylindrical part 21 that rotatably fits into the notch hole 14 of the push button 13.

By incorporating the movable body 15 into the cover 17 and fixing it to the operation plate 12, and further incorporating the push button 13 from the surface of the operation plate 12, as shown in FIG.
By moving the push button 13 up and down, the groove 19 of the movable body 15 rotates.

When the operation plate 12 to which the movable body 15, cover 17, and push button 13 are attached is placed and fixed on the panel stand 1, the groove 1 of the movable body 15 will open as shown in FIG.
9 and the cylindrical portion 11a at the tip of the vertical plate 11 of the water supply joint 7 are joined.

Here, by moving the push button 13 up and down,
The water supply joint 7 rotates via the movable body 15, and the discharge port 10 of the water supply joint 7 selectively moves above the washing side conduit 2 or the dewatering side conduit 3, as shown in FIGS. 4A and 4B, Water supply can be switched. At this time, when the push button 13 on the washing tank side is pressed, water is supplied to the washing side conduit 2 as shown in Fig. 4A, and when the push button 13 on the dehydration tank side is pressed, water is supplied to the dehydration side conduit 2 as shown in Fig. 4B. The structure is such that water is supplied to waterway 3.

In addition, in FIG. 5, an operation board 1 is mounted on the panel stand 1.
2, even when the water supply joint 7 is in the state of supplying water to the dewatering side and the movable body 15 is in the state of supplying water to the washing side, the inclined guide 2 of the movable body 15
0, the vertical plate 11 of the water supply joint 7
The cylindrical portion 11a at the tip is properly joined to the groove portion 19 along the guide 20. Therefore, the operation plate 12 can be fixed to the panel stand 1 regardless of the states of the water supply joint 7 and the movable body 15.

As is clear from the above embodiments, according to the present invention, the water supply can be switched between the washing side and the dewatering side with the easy operation of pressing a push button. When water is supplied to the dewatering side, pressing the push button closer to the dewatering side supplies water to the dehydrating side, making it easy for the operator to understand the water supply status and make selections. Furthermore, when assembling the panel stand and operation board, there is no need to position push buttons or water supply joints, so assembly is easy.
