Abstract
Abstract The portable water distiller is constructed to distill water placed within a housing and to dispense it directly into a separate storage vessel or to a distilled water space in the housing. In the latter case, the distillers are provided with a flexible impermeable partition which may be in the form of a bag and which divides the interior of the housing into a raw water space and a distilled water space. A boiler is disposed within the raw water space in order to vaporize the water and a compact radiator and fan assembly is mounted on top of the housing in order to condense the vapor into distilled water for delivery to the distilled water space within the housing. A heater-thermostat shut-off means is also provided for turning off the heater when the supply of water is too low.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
87 words
A portable water distiller comprising a self-supporting housing; a flexible impermeable partition mounted within said housing to define a raw water space and a distilled water space therein; a cap mounted on said housing, said cap including an opening for passage of raw water into said raw water space within said housing; a heater disposed in said housing for vaporizing the raw water in said raw water space; and means for condensing the vaporized raw water and for delivering the condensed water into said distilled water space.
Claim 2
Dependent Claim
87 words
A portable water distiller comprising a self-supporting housing; a flexible impermeable partition mounted within said housing to define a raw water space and a distilled water space therein; a cap mounted on said housing, said cap including an opening for passage of raw water into said raw water space within said housing; a heater disposed in said housing for vaporizing the raw water in said raw water space; and means for condensing the vaporized raw water and for delivering the condensed water into said distilled water space.
Claim 3
Dependent Claim
123 words
A water distiller comprising a self-supporting housing; a cap removably mounted on said housing; a flexible impermeable partition mounted within said housing to define a raw water space and a distilled water space therein; a heater disposed in said housing for vaporizing the raw water in said raw water space; and means for condensing the vaporized raw water and for delivering the condensed water into said distilled water space, said means including a radiator in said cap in communication with said raw storage space to receive a flow of vapor therefrom, a fan for blowing air over said radiator to condense the vapor therein to water and an outlet connected to said radiator for dispensing the water therefrom to said distilled water space.
Claim 4
Dependent Claim
123 words
A water distiller comprising a self-supporting housing; a cap removably mounted on said housing; a flexible impermeable partition mounted within said housing to define a raw water space and a distilled water space therein; a heater disposed in said housing for vaporizing the raw water in said raw water space; and means for condensing the vaporized raw water and for delivering the condensed water into said distilled water space, said means including a radiator in said cap in communication with said raw storage space to receive a flow of vapor therefrom, a fan for blowing air over said radiator to condense the vapor therein to water and an outlet connected to said radiator for dispensing the water therefrom to said distilled water space.
Claim 5
Dependent Claim
31 words
A water distiller as set forth in claim 2 which further comprises a boiler in said raw water space having an upper end in communication with an inlet to said radiator.
Claim 6
Dependent Claim
18 words
A water distiller as set forth in claim 2 wherein said outlet communicates with said distilled water space.
Claim 7
Dependent Claim
71 words
A water distiller as set forth in claim 4 which further comprises a boiler located in said raw water space, said boiler having an upper end in communication with said radiator to deliver vapor thereto and a port communicating said raw water space with the interior of said boiler to permit entry of raw water into said boiler interior, and wherein said heater is mounted in said interior of said boiler.
Claim 8
Dependent Claim
15 words
A water distiller as set forth in claim 5 wherein said boiler is thermally insulated.
Claim 9
Dependent Claim
30 words
A water distiller as set forth in claim 4 which further comprises a spout on said housing in selective communication with said distilled water space for dispensing distilled water therefrom.
Claim 10
Dependent Claim
24 words
A water distiller as set forth in claim 4 wherein said heater is supported from said cap and depends into said raw water space.
Claim 11
Dependent Claim
49 words
A water distiller as set forth in claim 8 which further comprises a boiler mounted within said partition in said housing and about said heater, said boiler having a port communicating said raw water space with the boiler interior to permit entry of raw water into said boiler interior.
Claim 12
Dependent Claim
27 words
A water distiller as set forth in claim 9 which further comprises a thermostat-heater shut-off means supported from said cap and depending into said raw water space.
Claim 13
Dependent Claim
43 words
A water distiller as set forth in claim 9 wherein said boiler has a mouth at an upper end and which further comprises a stopper mounted on an underside of said cap for closing said mouth, said heater being mounted in said stopper.
Claim 14
Dependent Claim
26 words
A water distiller as set forth in claim 11 which further comprises a conduit mounted in said stopper and communicating said boiler interior with said radiator.
Claim 15
Dependent Claim
24 words
A water distiller as set forth in claim 9 which further comprises a fixed guide within said housing for maintaining said boiler in place.
