22内に水を充満させるのである。The operation of the filtering device equipped with the automatic hot water reheating device at the time of dropping (hot water supply) will be described. The three-way valve 16 makes the reheating circuit 4 and the hot water supply circuit 3 communicate with each other, and the three-way valves 25 and 26 make the circulation circuit 2 Controlled to close the side. Then, when the drop opening / closing valve 19 is opened, hot water flows from the hot water supply circuit 3 into the reheating circuit 4, passes through the bath heat exchanger 6 and the circulation circuit 2, and is dropped into the bathtub 1. Therefore, in this case, the hot water does not pass through the filtration tank 22. Then, the water level detection operation of a certain procedure is performed, the water level is detected by the pressure sensor 7, and when the set water level is reached, the drop opening / closing valve 19 is closed. After that, open the three-way valve 25 to the circulation circuit 2 side, and filter the tank.
The inside of 22 is filled with water.

る。Next, the operation at the time of additional heating will be described. At this time as well, the three-way valve 26 closes the circulation circuit 2 side as in the case of dropping. Then, when the pump 5 is operated, hot water is sucked from the bathtub 1 into the circulation circuit 2 and returns to the bathtub 1 through the bath heat exchanger 6 and the flow control valves 31 and 32. Therefore, also in this case, the hot water does not pass through the filtration tank 22. The hot water is heated by a burner (not shown) when passing through the heat exchanger 6 for bath.

されたあと再び循環回路２のポンプ５吸込側に戻る。During filtration, the three-way valve 25 is controlled so that the filtration tank 22 side and the pump suction side of the circulation circuit 2 communicate with each other.
The three-way valve 26 is controlled to close in the direction of the backwash drain circuit 24, and the pump 5 is operated. Hot water is sucked from the bathtub 1 into the circulation circuit 2, and is divided into one flowing into the filtering circuit 23 and one discharged into the bathtub 1. The hot water that has flowed to the filtration circuit 23 passes through the filtration tank 22, and after removing fine dirt such as scales in the bath water, returns to the pump 5 suction side of the circulation circuit 2 again.

に洗い流され、逆洗水と共に排出される。Next, at the time of backwashing, the three-way valve 25 is controlled so as to connect the backwash circuit 30 side and the filtration tank 22 side, and the three-way valve 26 connects the filtration tank 22 side and the backwash drain circuit 24. Controlled. Further, the three-way valve 16 connects the hot water supply circuit 3 and the backwash circuit 30, and the drop opening / closing valve 19 is controlled to open. The hot water in the hot water supply circuit 3 flows into the backwash circuit 30, and the governor 27 throttles the flow rate so that the flow rate is always constant and the air separator 28 separates the water from the water.
22 is backflowed and drained from the backwash drain circuit 24. At this time, the backwash water flows back through the filter tank 22, so that the dirt adhering to the filter material in the filter tank 22 is peeled off by the backwash water, washed off, and discharged together with the backwash water.

る必要がない。Also, at this time, the three-way valve 25 or the three-way valve 26 fails for some reason, and the backwash circuit 30 is supplied with water pressure (usually 17.5 Kg / cm 2 ).
Even if it is fragile, the overpressure relief valve 39 discharges water to the drain pipe 40 to reduce the pressure.
There is no danger of it exploding. Further, since the water discharged to the drain pipe 40 joins the backwash drain circuit 24 and is discharged to the drain port (not shown), it is not necessary to separately provide the overpressure relief valve with a drain circuit outside the device.

でたりる。Next, the operation during the bubble bath operation will be described. The three-way valve is controlled in the same way as during reheating. When the air amount control valve 37 of the air supply pipe 36 connected to the bubble jetting device 35 is opened, bubbles are mixed into the discharge jet flow into the bathtub 1 to form a bubble bath. Further, each operation described above is controlled by a single control device including a microcomputer, and its operating device may correspond to the control device.
尚、上記動作はそれぞれ単独運転について説明したが、
濾過及び逆洗運転は追焚きあるいは泡運転と同時運転で
き、その時は三方弁25、26を切換えればよい。In addition, although each of the above operations has been described as an independent operation,
The filtering and backwashing operations can be operated at the same time as the reheating or foaming operation. At that time, the three-way valves 25 and 26 can be switched.

常に好都合なものである。(Effects of the Invention) As described above, according to the present invention, the backwash circuit is provided with the overpressure relief valve, and the water discharged from the overpressure relief valve is guided to the backwash drain circuit. This is very convenient because it prevents the parts such as the filter tank from bursting due to the water pressure during washing, and does not require a separate drainage circuit for the overpressure relief valve outside the equipment.
