Abstract
Abstract A distiller that includes a micro-wave generating unit in a housing, a water holding chamber for vaporizing water by micro-wave energy and means for conducting water vapor outwardly through the housing while preventing the passage of micro-waves, a condenser for the vapor and a distilled water reservoir. The distiller is automatically operated by sensor operated valves. The heat from the condenser may be used to preheat the feed water.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
136 words
A distillation system utilizing a conventional, kitchen-type micro-wave oven to supply energy for distillation of fluids comprising: (a) a conventional, kitchen-type micro-wave oven; (b) a boiler means dimensioned and designed to fit within the micro-wave oven; (c) tubular prevention means adapted and dimensioned to pass through a wall of the micro-wave oven, and adapted for quick connection to and disconnection from a connection means to the boiler means and a connection means to the condensing means and dimensioned and designed for preventing the passage of micro-wave energy to the exterior of the micro-wave unit while conducting vapors from the boiler means to the condensing means; (d) condensing means having a connection means adapted for quick connection to and disconnection from the prevention means, a heat exchange relationship with a cooling means, and a condensed fluid outlet.
Claim 2
Dependent Claim
136 words
A distillation system utilizing a conventional, kitchen-type micro-wave oven to supply energy for distillation of fluids comprising: (a) a conventional, kitchen-type micro-wave oven; (b) a boiler means dimensioned and designed to fit within the micro-wave oven; (c) tubular prevention means adapted and dimensioned to pass through a wall of the micro-wave oven, and adapted for quick connection to and disconnection from a connection means to the boiler means and a connection means to the condensing means and dimensioned and designed for preventing the passage of micro-wave energy to the exterior of the micro-wave unit while conducting vapors from the boiler means to the condensing means; (d) condensing means having a connection means adapted for quick connection to and disconnection from the prevention means, a heat exchange relationship with a cooling means, and a condensed fluid outlet.
Claim 3
Dependent Claim
15 words
The sytem of claim 1 including a fluid storage means adapted to receive condensed fluid.
Claim 4
Dependent Claim
18 words
The system according to claim 2 including a refrigeration means in energy flow communication with said storage means.
Claim 5
Dependent Claim
30 words
The system of claim 1 wherein the boiler means is removably disposed within the cooking chamber and further comprises a vessel having walls of heat resistant, substantially micro-wave transparent material.
Claim 6
Dependent Claim
53 words
The system of claim 1 wherein the prevention means further comprises a metallic micro-wave barrier of generally tubular construction which is fixedly mounted through the wall of the micro-wave oven by metallic micro-wave barrier fastening means so as to form a micro-wave barrier between the inner and outer portions of the micro-wave oven.
Claim 7
Dependent Claim
63 words
The prevention means of claim 5 wherein the conduit describes a path through the wall of the oven which is generally perpendicular to a surface of the wall and has a portion adjacent to the interior surface of the wall describing at least two turns of at least 90° and designed and dimensioned to prevent the transmission of micro-waves through the prevention means.
Claim 8
Dependent Claim
41 words
The system of claim 1 wherein the boiler is provided with means, responsive to a low level of fluid, and adapted to turn on the micro-wave oven and responsive to a high level of fluid to turn off the micro-wave oven.
