ABSTRACT:
A water filtering, sterilizing and heating apparatus is provided. The apparatus includes filter tank provided with activated carbon therein, to filter bacteria, miscellaneous impurities and odor in water. The output of the filter is coupled to a microwave oscillator to vibrate and churn the water coming from the filter tank. The water from the microwave oscillator is coupled to an ultraviolet light sterilizing tank having an ultraviolet lamp disposed vertically in the center thereof. A storage tank is provided to receive and store the water coming from the ultraviolet light sterilzing tank. The fluid level in the storage tank is maintained by automatically controlling the passage of water thereto by means of an electromagnetic valve actuated by a micro switch responsive to displacement of a float. The temperature of the stored water being kept at a preset temperature by means of a heater and a temperature sensor.
