In addition to constantly replacing the water in the faucet with fresh water, by switching a switching valve that is separate from the valve that opens and closes the faucet, water from the water supply pipe can be discharged directly from the outlet of the faucet. Except for applying pressure to the operating handle of the switching valve, the switching valve is automatically switched by water pressure so that the water is discharged through the circulation tank again, and moreover, it is possible to take up a large space around the faucet. The faucet has a good appearance and there is no fear of the faucet falling off.

The illustrated embodiment will be described below.

In the drawing, the faucet main body A has a connection pipe 2 having a connection part 1 to a water supply pipe (not shown),
The connecting pipe 2 communicates with a discharge vibro through a first communication port 3 having a valve body 4 that is opened and closed by a handle 20, and the discharge vibro is connected to a water supply pipe 7.

Reference numeral 5 in the figure is a valve chamber.

The open end of the water supply pipe 7 is connected to the inner bottom of a sealed circulation tank 9, as shown in FIG.

A drainage pipe 10 connected to the upper part of the above-mentioned circulation tank 9 through a connecting plug 8 is connected at an upper end to a drainage channel 12 connected to the faucet main body A through a connecting part 11.

Although the drain pipe 10 in the illustrated example encloses the water supply pipe 7 and has a double structure with the water supply pipe 7, it is not limited to this structure.

The above-mentioned drainage waterway 12 is not shown in the drawing, but the faucet main body A
It is communicated with the discharge port 13 through water channels running inside both sides of the discharge port 13.

The aforementioned connection pipe 2 and discharge port 13 are connected to the switching valve 1.
They are communicated through a second communication port 17 having a diameter of 4.

The above-mentioned switching valve 14 has two positions, as shown in FIG. 1, in which the first communication port 3 is open and the second communication port 17 is closed, and in a first position, as shown in FIG. The operating shaft 19 is attached to an operating shaft 19 so as to be rotatable between two positions: a second position in which the first communicating port 3 is closed and a second communicating port 17 is open. The operating handle 18 is projected outside A.
is attached.

The illustrated switching valve 14 has a pressure receiving plate portion 15 at its lower end with a shaft 16.
is hinged, and a stopper 15' is provided protruding from the side surface of the pressure receiving plate portion 15 on the first communication port 3 side.

Because of this structure, when the switching valve 14 is rotated to the above-mentioned second position and is in the state shown in FIG. 2, the stopper 15
' is in contact with the peripheral wall of the connecting pipe 2, and the pressure receiving plate portion 15 protrudes into the connecting pipe 2, so that it can receive the pressure of the water flow flowing from the water pipe.

Due to this received pressure, the switching valve 14 is moved from the second position to the first position.
When a rotational force is applied to the operating handle 18 to rotate it to the first position shown in the figure, and the rotational force acting on the operating handle 18 is removed, that is, when the finger is released, the switching valve 14 automatically moves to the first position. is rotated to the position.

In addition, a check valve 21 is installed at a position near the connection part 1 of the connection pipe 2 to prevent backflow of water from the connection pipe 2 to the water supply pipe.
It's decorated.

With the above configuration, when the connection part 1 connects the faucet main body A to the water supply pipe by turning the connection part handle 20 and opening the valve body 4, water flows from the connection pipe 2 through the first communication port 3. The water reaches the discharge vibro, passes through the water supply pipe 7, and flows into the circulation tank 9.

The air in the circulation tank 9 is discharged through the drain pipe 10 and replaced with water.

When the valve body 4 is opened, the switching valve 14 switches between the sheet metal and the second
Even if it is in the state shown in the figure, the pressure of the flowing water will not be absorbed by the pressure receiving plate 15.
As a result, water immediately enters the state shown in FIG. 1 and water flows into the circulation tank 9.

When the circulation tank 9 becomes full, the water in the tank continues to be discharged from the drain pipe 10, through the drain channel 12 of the faucet main body A, and from the discharge port 13, and when the valve body 4 is closed, the water is discharged. Stop.

When the valve body 4 is opened again after the above-mentioned condition has been reached, new water flows into the circulation tank 9 in the same manner as described above, and the water that had accumulated in the tank flows through the drain pipe 10. The water is discharged from the discharge port 13, and the circulation tank 9 is always filled with fresh water.

When the operating handle 18 is used to rotate the switching valve 14 from the first position shown in FIG. 1 to the second position shown in FIG. 2, and the operating handle 18 is maintained in that position by hand, Water is directly discharged from the discharge port 13 through the second communication port 17 from the connecting pipe 2 section.

This phenomenon is the same even if the valve body 4 is opened while the valve body 4 is open, or even if the valve body 4 is opened after the switching valve 14 is operated.

When the operating handle 18 is released, the water pressure of the drift ice acts on the pressure receiving plate 15 of the switching valve 14, so the switching valve 14 is immediately moved from the second position shown in FIG. 2 to the first position shown in FIG. The water is rotated to the position shown in FIG.

As described above, according to the present invention, by opening the faucet, tap water flows into the circulation tank, which is a water storage tank, and the water accumulated in the tank is discharged to the drainage channel in the faucet. By discharging water from the outlet of the faucet, the water in the circulation tank can be constantly replaced with fresh water, and by switching a switching valve that is different from the valve that opens and closes the faucet, water from the water supply pipe can be directly supplied to the outlet of the faucet. It is also possible to discharge the water from the tank, and in this case, without pressurizing the operating handle of the switching valve, the switching valve is automatically switched by water pressure so that the water is discharged through the circulation tank again. Furthermore, it is possible to take up a large space around the faucet, and the appearance is good and there is no fear of the faucet coming off.
