[0002]

2. Description of the Related Art Conventionally, a water supply device equipped with a cartridge having a function of removing calcium and trihalomethane in tap water and adding a component beneficial to the human body to tap water has been widely used. In such a water supply device, a cartridge is provided between a water supply pipe and a discharge pipe of the raw water, and the raw water passes through the cartridge. In order to achieve this, branch valves having various structures have been developed.

FIG. 6A is an external view of a conventional water supply device, in which a first cartridge 5 is provided on a side surface of a water tap main body 3. In this water supply device, the branch valve 4 is disposed in the middle of the flow of water from the water stop cock 1 to the first cartridge 5, and the supply of water to the first cartridge 5 is started by operating the branch valve 4. Alternatively, it can be stopped. The water that has passed through the first cartridge 5 is discharged from the discharge pipe 7 through a water passage inside the water tap main body 3.

FIG. 6B is an external view of another conventional water supply apparatus, in which a second cartridge 6 is provided in a sink. A branch valve 4 is arranged in the middle of the flow path from the water-side stopcock 1 to the second cartridge 6, and the supply of water to the second cartridge 6 can be started or stopped by operating the branch valve 4. Also in this water supply device, the water that has passed through the second cartridge 6 is discharged from the discharge pipe 7 through the water passage inside the water tap main body 3.

[0005]

On the other hand, with the recent technological development and diversification of life, various functions have been required for cartridges as described above, and tap water is simply filtered as in the past. In addition to these, addition of an active ingredient is performed. However, in the conventional water supply apparatus, as described above, there is only an idea that each cartridge is provided independently, and there is no apparatus provided with a plurality of cartridges.

Accordingly, an object of the present invention is to achieve the above-mentioned multi-functionality with a relatively simple structure in a water supply device provided with a cartridge.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention comprises a hydrant body having a built-in branch valve and a discharge pipe connected to the hydrant body. A plurality of cartridges capable of filtering raw water, adding components to the raw water, or changing the water quality are provided in the middle of the flow path connecting the discharge ports of the pipes. According to the present invention,
Multifunctionalization can be achieved with a relatively simple structure.

The water is supplied to the supply port 10 of the cartridge 5 and supplied to the first cartridge 5. Since the water outlet side of the first cartridge 5 is connected to the discharge pipe 7, the flow of the water is again changed to the branch valve 4.
It is discharged to the outside through the discharge pipe 7 without flowing into the inside. That is, water that has passed only through the first cartridge 5 can be obtained. At this time, the water supply port 11 of the fixed ceramic plate 8 to the second cartridge 6 overlaps with the second long groove 16 of the movable ceramic plate 14, but the other four supply ports of the fixed ceramic plate 8, etc. Since it does not overlap with any of the above, the water passage is shut off. Similarly, the water communication port 13 of the fixed ceramic plate 8 to the discharge pipe 7 overlaps with the third long groove 17 of the movable ceramic plate 14.
Since it does not overlap with any of the other four supply ports of the fixed-side ceramic plate 8, it is blocked as a water passage and prevents the backflow of water from the discharge pipe 7.

In the serial mode shown in FIG. 5D, the water flowing in from the hydrant connection port 9 of the fixed ceramic plate 8 is supplied to the second cartridge 6 of the fixed ceramic plate 8 by the second long groove 16 of the movable ceramic plate 14. Water is supplied to the second cartridge 6. Then, the water that has passed through the second cartridge 6 flows into the branch valve 4 again, and the first
The water supply port 1 to the first cartridge 5 of the fixed ceramic plate 8 from the return port 12 of the water from the cartridge 5 through the first long groove 15 of the movable ceramic plate 14
0 and is supplied to the first cartridge 5. Since the water outlet side of the first cartridge 5 is connected to the discharge pipe 7, the flow of the water is discharged to the outside through the discharge pipe 7 without flowing into the branch valve 4 again. That is, water that has passed through both the first cartridge 5 and the second cartridge 6 can be obtained. At this time, the water communication port 13 of the fixed-side ceramic plate 8 to the discharge pipe 7 is blocked by the flat portion 30 of the movable-side ceramic plate 14 to prevent the backflow of water from the discharge pipe 7.
