めに設けた定圧弁である。Filtered water is water until the water level of the electrode rod E 1 to initially, or hot water by the heater 2, or thermistor 4, a cold water conditions. When the cold / hot water is supplied from the water supply port B, the water level in the water storage tank 1 gradually decreases. Water level electric valve 3 opened by the control circuit 5 when it reaches up to E 2, filtered water that has passed through the filtration cartridge 7 is supplied from the raw water supply port A is water storage tank 1. And when the water level reaches the electrode rod E 1, closes the electric valve 3 by the control circuit 5, the water storage tank 1
, The storage of filtered water is stopped. At this time, the time during which the electric valve 3 is open is measured by the time measurement circuit 8. Since the filtration flow rate is large while the filtration cartridge 7 is still new, the speed at which the filtered water accumulates in the water storage tank 1 is high, and the time during which the electric valve 3 is open is short. As the filtering cartridge 7 approaches the replacement time, the time during which the electric valve 3 is open becomes longer. And if it is over a certain time,
It is determined that it is time to replace the filtration cartridge 7, and the time measurement circuit 8 displays on the filtration cartridge replacement time display section 9 that the replacement time for the filtration cartridge has come. Reference numeral 10 denotes a constant pressure valve provided to suppress a change in the amount of filtered water due to pressure.
