Abstract:
An apparatus for extracting potable water from the environmental air comprising:a housing having an air inlet with an air filter, an air outlet and an air blower for drawing air into the housing through the air inlet and pushing it out of the housing through the air outlet; a moisture collecting system having dew-forming surfaces disposed so that the air drawn into the housing passes therethrough and moisture from the air condenses in the dew-forming surfaces; a water reservoir capable of receiving water collected as moisture in said moisture collecting system and having a bottom and a side surface constituting a surface of revolution around a longitudinal axis of the reservoir, the reservoir having an outlet port formed at the bottom thereof along said longitudinal axis, for the withdrawal of water from said reservoir, and a circulation inlet port formed in said side surface, said circulation inlet port being designed so as to enable the introduction of water into the reservoir tangentially to said side surface; a water circulation line extending from said outlet port to said inlet port of the water reservoir through a water filtration and sterilization system to provide the circulation of water through said reservoir by means of a pumping device; a water dispensing valve for the external dispensing of water from the circulation water line.
