Abstract: There is disclosed a water distiller, primarily for producing water for human consumption which includes a boiler with an electric heater, a fractional distillation tower extending about two or more feet above the boiler, a gas trap at the top of the tower, and a steam conduit exiting from the tower below the gas trap and leading into a condensation tube with a water-cooled jacket. The boiler and tower are of uniform cross-section to facilitate cleaning by running a swab through this tube. An unprocessed water inlet is located in the bottom of the water jacket, and at the top of the water jacket is an exit orifice for preheated input water. A conduit for preheated input water leads to the bottom-most part of the boiler of the distiller. An overflow conduit is provided which is directly opposite the preheated water inlet; the highest point of the overflow conduit serves to automatically regulate the depth and volume of water in the boiler.

Abstract: There is disclosed a water distiller, primarily for producing water for human consumption which includes a boiler, a distillation tower extending about two or more feet above the boiler, and a steam conduit exiting from near the top of the tower leading into a helically grooved condensation tube with a water-cooled jacket. The boiler and tower are of uniform cross-section to facilitate cleaning. The water jacket has a water inlet located in the bottom and an exit orifice for preheated input water at the top. A conduit from the orifice leads to an evaporator for volatile impurities on top of the tower, and a conduit for preheated input water leads to the bottommost part of the boiler from the evaporator. An overflow conduit with an intermittent siphon is provided connected to the bottom of the boiler; the highest and lowest points of the siphon serve to automatically regulate the maximum and minimum depths of water in the boiler.
