<p>PROBLEM TO BE SOLVED: To solve the problems that it is necessary to exchange an activated carbon cartridge because the adsorptivity is reduced with the increase of the water floe quantity in the water purification by activated carbon and it is necessary to transport water or a water heater in order to transfer the water purified by a purifier to the water heater, so that much labor and time are required. SOLUTION: The maintenance free photocatalytic water purifying apparatus for decomposing and removing a harmful material in a treating water has hot water storage vessel 28 for storing at least hot water, a hot water supply part composed of a heater 29 for heating the water in the hot water storage vessel, a water discharge passage 25 for discharging water to the outside, a water supply passage 27 for supplying water to a hot water supply part, a switching valve 32 for switching the water discharge passage 25 and the water supply passage 27 to each other, a reaction passage 1 capable of efficiently transmitting light from a light source 9 and a photocatalytic body 2 in the reaction passage.</p> |
