Abstract
An apparatus for fluid distillation in general, and in particular, or water, adapted for consumer or home use, but capable of being made and operated so that it is suitable for separating solvents and solutes and other industrial use. The apparatus includes a housing having divider structure to form one or more compartments for receiving water to be distilled. The divider structure also presents a fluid passage for receiving water vapor which is formed when the upper portion of the water in the housing is boiled by a heater. An aerator is provided in the housing below the heater and in a location within the water compartment. The aerator operates to direct air under a slight pressure into the water so that air bubbles can be generated in the water. The air bubbles will rise and break the surface of the water as the upper part of the water is being boiled by the heater. This causes a vapor pressure to be generated in the space above the water level and water vapor is then caused to move through the fluid passage downwardly to a lower chamber in which the water vapor is collected as a condensate. As the water vapor moves downwardly in the fluid passage, it moves in heat exchange relationship to the water in the compartment of the housing. Several embodiments of the housing of the present invention are disclosed.
