循環浄化装置が提案されている。2. Description of the Related Art In recent years, a bath that can be used for a 24-hour bath in a home bath has been provided. In this case, it is necessary to purify and sterilize the bathtub water constantly or periodically so that the bathtub water in the bathtub 10 can be used for a long time. For this purpose, as shown in FIG. 8, a circulation pump 2 for circulating bath water and a filtration tank 3 for filtering the bath water are provided, and a bypass 4 is provided in the circulation water 1. 4 is provided with a salt dissolving tank 19 and an electrolytic tank 6 having a pair of electrodes 5 built-in downstream thereof. The downstream side of the bypass 4 is connected to the primary side of the filtration tank. There is proposed a bath tub water circulation purifying apparatus in which a valve 7 is provided at the same time and a valve 18 is provided upstream of a salt dissolving tank 19.

After opening, while turning on and off the circulation pump 2 in small increments (that is, while inching the circulation pump 2),
The salt concentration in the electrolytic bath 6 is measured while measuring the electric conductivity between the pair of electrodes 5 provided in the electrolytic bath 6, and when the target salt concentration is reached, the circulation pump 2 is stopped and the valve 18 is closed. Next, a voltage is applied between the electrodes 5 of the electrolytic cell 6 to generate free chlorine. Next, the valve 7 on the upstream side of the electrolytic cell 6 is opened, and the chlorine water generated in the electrolytic cell 6 is supplied to the bath water for sterilization.

Since the on / off operation of the circulation pump 2 is repeated little by little, the salt dissolving tank 1 is turned off when the circulation pump 2 is turned off between on and on.
Since the specific gravity of the saline solution in the tank 9 is higher than that of water, there is a problem that the salt solution flows out to the upstream side through the opened valve 18, so that the salt is wasted and the salt in the salt dissolving tank 19 is consumed. There is a problem that becomes faster.

However, in the present invention, when the salt solution is supplied from the salt dissolving tank 19 to the electrolytic tank 6, the water can flow into the salt dissolving tank 19 from the second branch 17 via the opened valve 18. Further, since a check valve 25 for preventing water from flowing back to the second branch 17 via the valve 18 opened from the salt dissolving tank 19 is provided, water is supplied upstream from the salt dissolving tank 6 to the water. Also, the salt solution having a large specific gravity is prevented from flowing out due to the difference in specific gravity, and wasteful consumption of salt in the salt dissolving tank 19 can be prevented.

If a check valve 11 having a directionality in which water flows only from 9 to the electrolytic cell 6 is provided, water flows backward from the electrolytic cell 6 to the salt dissolving tank 19 by water pressure when the circulating pump 2 is operating. Even if the water level in the salt dissolving tank 19 is going to rise, it is blocked by the check valve 11. As a result, the water level in the salt dissolving tank 19 rises more than the predetermined water level, and the excess saline solution is released from the salt dissolving tank 19 by releasing the pressure by stopping the operation of the circulation pump 2. It is possible to prevent a phenomenon that the saline solution flows into the tank 6. That is, when the circulation pump 2 is turned on / off or the flow path is changed, the salt dissolving tank 19 is switched from the electrolytic tank 6 by the respiration.
The saline solution does not flow into the container. Therefore, it is possible to prevent the salt concentration from being unable to be controlled during the electrolysis and the salt from being consumed in the salt dissolving tank 19 from being consumed quickly.

る。According to the first aspect of the present invention, when the salt solution is supplied from the salt dissolving tank to the electrolytic tank, the salt solution is opened, and the salt solution supplied from the salt dissolving tank is supplied to the electrolytic tank. When chlorine water generated by electrolysis is discharged from the discharge port, a valve that closes is provided upstream of the salt dissolving tank in the second branch, and the circulating pump is turned on and off when the valve is open. When supplying salt solution from the salt dissolving tank to the electrolytic tank repeatedly in small increments,
To allow water to flow from the second branch to the salt dissolving tank via the opened valve and to prevent water from flowing back to the second branch via the valve opened from the salt dissolving tank. Since a check valve is provided, when the saline solution is supplied from the salt dissolving tank to the electrolytic tank to bring the inside of the electrolytic tank to a predetermined salt concentration, the circulating pump is turned on and off with the valve opened in small increments. Even if it is repeated, when the circulating pump that repeats the above on and off in small increments is turned off, the check valve prevents the salt solution having a large specific gravity in the salt dissolving tank from flowing backward through the valve opened from the salt dissolving tank to the upstream side. As a result, wasteful consumption of salt in the salt dissolving tank can be prevented, and the cost can be reduced.
