PURPOSE:To prevent the rottenness of stored water, and to supply tasty drinking water by supplying the outside with water introduced into a water tank through a filter medium and a sterilizer while circulating purified water at all times through the filter medium. CONSTITUTION:A water tank 11 is installed, and a fixed quantity of well water, city water, etc., is introduced through a water-supply installation such as a ball tap 12. The inside of the tank 11 is filled with a filter medium 13, and filtered water is stored on the bottom of the tank 11. A pump 14 is mounted, and water on the bottom of the tank 11 is sprayed onto the filter medium 13 from a nozzle 22 through a first clear water introducing pipe 32 and a circulating water supply pipe 21. When a cock on the outside connected to a clear water supply pipe 36 is opened, a sterilizer such as an electric sterilizer 15 is supplied with water in the tank 11 through a second clear water introducing pipe 35 from the pump 14. The cock on the outside is fed with sterilized water through the pipe 36. Accordingly, the rottenness of water in the tank can be prevented while tasty drinking water purified at all times can be fed. |
