Abstract
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.

Claim 3
Dependent Claim
34 words
The distiller according to claim 1 wherein the steam chamber further including means for mounting the baffle means so that the facing surface portion extends in a nonparallel relationship with respect to the tray.
Claim 4
Dependent Claim
31 words
The distiller according to claim 1 wherein the tray and top portion of the steam chamber are made of plastic material, and wherein the baffle means is made of metal material.
Claim 5
Dependent Claim
27 words
The distiller according to claim 1 wherein, in use, a portion of at least one of the depending sidewalls extends into the water contained in the tray.
Claim 6
Dependent Claim
34 words
The distiller according to claim 1 wherein said check valve is vertically oriented so that in the absence of steam pressure said communication is closed by the force of gravity exerted on the valve.
