Abstract
A steam chamber has a bottom portion that defines a tray for holding water to be distilled and a top portion for collecting steam created in the chamber by heating the water in the tray. An outlet conducts steam from the top portion of the steam chamber to a condenser. A check valve occupies the outlet for opening communication between the steam chamber and the condenser in response to steam pressure above atmospheric pressure in the steam chamber and for closing communication between the steam chamber and the condenser in the absence of the steam pressure in the steam chamber. In a preferred arrangement, a baffle member extends between the tray and the top portion of the steam chamber for allowing steam to enter the top portion of the steam chamber while preventing water globules carried in the steam from entering the top portion of the steam chamber.
