Since water that has entered the inside and is replaced with air flows into the overflow chamber 65, water easily accumulates in the overflow chamber 65, and therefore the accumulated water is appropriately flowed to the bath reheating circulation path 30 side. I had to drain it.
For this reason, in addition to the drawback that it takes time to drain the overflow chamber 65, the drainage solenoid valve 67, the three-way switching valve 70, the bypass path 31a for both transportations, and the check valve 31b are required, which leads to an increase in cost. Also, when the flow rate of hot water supply is small, or when the bathtub is located lower than the edge cutoff valve device 60, etc., the overflow of the overflow chamber 65 by the first check valve 62 becomes insufficient and water enters the overflow chamber 65. However, there was a problem that it became full and overflowed to the outside.
And for this reason, the overflow solenoid valve 66 is required,
This led to a further increase in cost.

The first hot water supply check valve and the second hot water supply check valve flow into the bath-fired circulation path and are introduced into the bathtub. During hot water supply, water also flows into the air charge chamber that is connected to the side, but the electromagnetic air charge valve forcibly closes the air charge port on the ceiling from the air charge chamber, so overflow occurs. do not do.
Therefore, it is not necessary to increase the volume of the air charge chamber. In addition, water that flows in through the first hot water supply check valve at the beginning of hot water supply or when hot water supply is stopped tends to flow to the second hot water supply check valve side below the hot water supply check valve and does not enter the side air charge chamber. In addition, a small amount of water accumulated in the air charge chamber flows into the hot water supply passage along with the hot water supply water through the second hot water supply check valve toward the bath reheating circulation path at the next hot water supply. Further, when the hot water supply is not performed, the hot water supply valve is closed and the electromagnetic air charge valve opens the air charge chamber. Therefore, the air that has entered the air charge chamber from the outside does not have the first hot water supply check valve and the second hot water supply check valve. Enter the hot water supply path between the hot water supply check valve and the hot water supply check valve to cut off the water flow. If water enters the air charge chamber for any reason while not hot water is supplied, the electromagnetic air charge valve is located in the air charge chamber and faces the air charge port on the ceiling. The water pressure prevents the electromagnetic air charge valve from closing the air charge port and overflowing water to the outside. As described above, in the configuration of the present invention, since it is possible to reliably prevent water from overflowing from the air charge chamber, it is not necessary to use a special overflow solenoid valve for overflow prevention, Also, since water does not collect in the air charge chamber, there is no need to specially drain the air charge chamber, and therefore a dedicated drain solenoid valve, a three-way switching valve between the hot water supply path and the bath reheating circulation path, etc. It is unnecessary, and cost reduction can be achieved by saving members. Also, it is not necessary to take the time exclusively for drainage.

Is closed, and the electromagnetic air charge valve 96 is closed. Hot water from the hot water supply passage 51 directly connected to the water supply or the like enters the edging valve device 90 with high pressure from the opened hot water supply solenoid valve 91, and
Passing through the hot water supply check valve 92, falling downward, further flowing through the second hot water supply check valve 95 into the bath reheating circulation path 30, and passing through both the return pipe 31 and the forward pipe 32 to the bathtub. Introduced in 20. Since the electromagnetic air charge valve 96 forcibly closes the air charge port 93a of the air charge chamber 93 during hot water supply, water is reliably prevented from flowing out through the air charge chamber 93. When the bath hot water supply of a predetermined amount is completed, the controller 80 closes the hot water supply solenoid valve 91 and releases the electromagnetic air charge valve 96 from the forced close state. As a result, the electromagnetic air charge valve 96 is charged by its own weight with the air charge port 93.
Release a. When the air charge port 93a is opened, air flows from the air charge port 93a to the air charge chamber.
It passes through 93 to enter the hot water supply passage between the first hot water supply check valve 92 and the second hot water supply check valve 95, and cuts off the water flow. At the end of hot water supply, the water that has flowed downward from the first hot water supply check valve 92 or the water in the air charge chamber 93 flows down toward the second hot water supply check valve 95 below, and while water pressure is present, the second Flows through the hot water supply check valve 95 to the side of the bath reheating circulation path 30. Therefore, almost no water accumulates in the air charge chamber 93. Therefore, it is not necessary to drain the water in the air charge chamber 93. Of course, since the water remaining upstream of the second hot water supply check valve 95 flows out together with the next hot water supply, the accumulated water amount does not gradually accumulate.

コストを低減することができる。According to the present invention having the above-described structure and operation, the bath drop hot water supply rim cutoff valve device according to claim 1 forcibly closes the air charge port from the inside of the air charge chamber only when hot water is supplied. An electromagnetic air charge valve is installed to prevent water from leaking from the air charge chamber to the outside when hot water is supplied. Even if it enters, the electromagnetic air charge valve is pushed by the water pressure to close the air charge port, so that overflow can be reliably prevented. Therefore, there is no need for a special overflow solenoid valve for preventing overflow. Further, when the hot water supply is finished, the electromagnetic air charge valve releases the closing of the air charge port, so that the outside air can enter the hot water supply passage side through the air charge chamber, and the edge of the water flow can be cut off. Further, the water remaining in the edge valve device during hot water supply or at the end of hot water flow down to the second hot water check valve side below the first hot water check valve, and the second hot water check valve is still open. While it is running, it flows away to the bath reheating circulation side, so little water remains, and it does not flow much to the air charge chamber side on the side of the hot water supply passage. And the remaining water is discharged together with the hot water at the next hot water supply,
Residual water will not accumulate and fill the air charge chamber. Therefore, since water does not collect in the air charge chamber etc., it is not necessary to take a dedicated time for draining, and a drain solenoid valve and other members associated with performing a special drain operation, for example, bath reheating from the hot water supply channel A three-way switching valve or the like at the connection position to the commercial circulation path is not necessary, and the manufacturing cost can be reduced.
