ABSTRACT:
A water purification device comprises a raw water channel forming plate extending spirally along the inner wall of a filter tank. A collector for collecting filtered water, positioned in the layer of the filter medium substantially at the center of the raw water channel forming plate, is also disclosed. Since the raw water is filtered from the periphery of the layer of the filter medium and the continuous raw water channel formed by the spirally extending raw water channel forming plate enables the number of influx points of raw water into the raw water channel to be reduced to one at a minimum, the structure is simplified and manufacture costs are reduced.
