装置を必要としないものである。Here, in the bath water circulation purifying apparatus of the present invention, during normal circulation operation, all of the valves 12, 15 and 16 are opened, and the three-way valves 20 and 23 are closed, and the circulation pump 2 is closed.
In this case, the circulation pump 2 is operated to operate the circulation water passage 1 through the suction port 14.
A part of the bathtub water sucked into the tank is heated by the heater 3 and sent to the discharge port 7 side, and another part of the bathtub water flows to the bypass passage 4 and passes through the filter tank 5 when the filter medium is filtered. It is purified by being filtered by 5a and sent to the discharge port 7 side. Then, when the heated bathtub water flowing through the circulation channel 1 passes through the throttle portion 7a provided near the inside of the discharge 7, the purified bathtub water flowing through the bypass channel 4 flows through the circulation channel 1 by the ejector effect. The bathtub water is sucked into the bathtub water side and merged, and the merged bathtub water is jetted from the discharge port 7 into the bathtub water in the bathtub 6 as jet water. This is the “normal circulation mode”. Here, the downstream end of the bypass passage 4 is connected to the circulation passage 1 at a throttle portion 7 a provided near the discharge port 7 to the bath 6 of the circulation passage 1, and is bypassed by the bathtub water flowing through the circulation passage 1. Since the bathtub water flowing through the path 4 is sucked by the ejector effect, the bathtub water flowing through the filtration tank 5 flows smoothly and merges with the heated bathtub water flowing through the circulation flow path 1. As a result, the bathtub water can pass through the filter medium 5a of the filter tank 5 smoothly and be effectively purified. Then, by connecting the downstream end of the bypass passage 4 to the throttle part 7a provided near the discharge part 7 in order to jet the bathtub water from the discharge part 7, the filter medium 5a can be smoothly connected as described above. No special device is required to allow the air to pass through.

のである。In the sterilization (or bacteriostatic) operation, the operation is performed in the order of “salt water supply” mode → “electrolysis” mode → “chlorine water supply” mode. That is, the valve 12, the valve 15, and the valve 16 are all opened, and the three-way valve 20 is opened only on the side of the second branch 19 to allow bathtub water to flow to the second branch 19. By operating the circulation pump 2 in a state where 23 is closed, the salt solution is supplied from the salt dissolving tank 22 to the electrolytic tank 21 (this is a “salt water supply” mode). After supplying the saline solution to the electrolytic cell 21 in this manner, a voltage is applied to the electrode 26 with all of the valves 12, 15, and 16 opened and the three-way valves 20 and 23 closed. Electrolysis produces chlorine (this is the "electrolysis" mode). In this case, the circulation pump 2 is operated. Next, the valve 12, the valve 15, and the valve 16 are all opened, and the three-way valve 20 is opened only on the first branch passage 18 side so that bathtub water flows to the first branch passage 18 side.
Further, when the three-way valve 23 is closed and the circulation pump 2 is operated in this state, the chlorine water in the electrolytic cell 21 is supplied to the filtration tank 5, passes through the filter medium 5a and flows into the bath 6 together with the bath water (this is "Chlorine water supply" mode). By flowing chlorine water in the circulation channel 1 in this manner, bath water and pathogenic bacteria in the apparatus are suppressed, and slime that gives discomfort is removed.

In this case, the bath head water flows backward from the upstream side of the bypass 4 to the filtration tank 5 and the salt dissolving tank 22 due to the head pressure. However, in the present embodiment, the bathtub water flows only from the filtration tank 5 side to the downstream side of the bypass passage 4 downstream of the filtration tank 5 and prevents the bathtub water from flowing backward from the downstream side to the filtration tank 5 side. Since the check valve 10 is provided, even when the filtration tank 5 and the chlorine generator A are disposed below the water surface of the bathtub, the check valve 10 allows the hot water in the bathtub 6 to flow from the bypass passage 4. It is possible to prevent the water from flowing back to the filtration tank 5 and the salt dissolution tank 22 and overflowing from the filtration tank 5 and the salt dissolution tank 22.

The bathtub water flowing through the bypass passage is sucked by the ejector effect by the water flow, and the manual open / close valves are provided on the upstream side of the circulation pump in the circulation passage and on the downstream side of the heater, respectively. A check valve is provided on the downstream side to allow bathtub water to flow only from the filtration tank side to the downstream side, and to prevent backflow of bathtub water from the downstream side to the filtration tank side. When performing maintenance and inspection of the tank or replenishment of the salt that is the raw material of chlorine generated in the chlorine generator, even if the filtration tank or the chlorine generator is placed below the surface of the bathtub, the check must be made. Hot water in bathtub by valve The bath does not flow backward from the bypass to the filter tank or chlorine generator, and does not overflow from the filter tank or chlorine generator, making it easy to replace, maintain, inspect, refill, etc. It does not get wet with water, and it is only necessary to provide a check valve, so even with the existing bathtub water circulation purification device, the above-mentioned water leakage can be prevented only by installing a check valve in the bypass. The effect can be easily exerted.

置。1. A circulation pump for circulating bath water in a circulation channel, a heater provided downstream of the circulation pump in the circulation channel, a bypass branched from the circulation pump and the heater in the circulation channel, and a bypass. In a bath tub water circulation / purification device provided with a chlorine generator provided in the middle of the road and a filter tank for purifying bath water flowing through the bypass at a downstream side of the chlorine generator, the downstream end of the bypass circulates. The bathtub water flowing through the bypass passage is sucked by the ejector effect by the water flow of the bathtub water flowing through the circulating water passage connected to the throttle portion near the discharge port to the bathtub of the waterway, and is arranged upstream of the circulation pump of the circulation waterway. Manual open / close valves are provided on the side and the downstream side of the heater, respectively, so that the bath water flows only from the filtration tank side to the downstream side downstream of the filtration tank in the bypass path, and from the downstream side to the filtration tank side. A bath water circulation / purification device comprising a check valve for preventing back flow of bath water.
