Non-spitting noiseless electric steam vaporizer
First Claim
1. A vaporizer comprising a liquid container having an upper opening, a cap positioned on said container overlying said upper opening, said cap having a steam outlet opening and a vent opening, electrodes depending into said container from said cap, at least one tube depending from said cap and communicating with said vent opening, an inner housing cooperating with said cap to define a steam collection space communicating with said steam outlet and including a depending heating chamber surrounding said electrodes and having a water inlet opening therein communicating with the container, an opening between said steam collection space and the interior of said container, said inner housing including isolated conduit means open to said container externally of said heating chamber, said at least one tube communicating with said conduit means to form a closed isolated steam flow path from the interior of said container to said vent opening, and fastening means detachably securing said cap and said inner housing in an assembled condition.

Abstract
A cool-running noiseless, non-spitting electric steam vaporizer has a liquid container with a top opening closed by a cap having a steam outlet and a vent opening. An inner housing cooperates with the cap to define a steam collection space communicating with the steam outlet and includes a depending heating chamber communicating with the steam collection space and surrounding a pair of electrodes extending into the container from the cap. An opening between the steam collection space and the container allows excess steam produced during periods of rapid boiling to flow to the container. An isolated conduit extending through the steam collection space from the container interior to the vent opening allows the excess steam to be exhausted without noise or spitting. An insulative double walled outer housing surrounds the heating chamber.

- 1. A vaporizer comprising a liquid container having an upper opening, a cap positioned on said container overlying said upper opening, said cap having a steam outlet opening and a vent opening, electrodes depending into said container from said cap, at least one tube depending from said cap and communicating with said vent opening, an inner housing cooperating with said cap to define a steam collection space communicating with said steam outlet and including a depending heating chamber surrounding said electrodes and having a water inlet opening therein communicating with the container, an opening between said steam collection space and the interior of said container, said inner housing including isolated conduit means open to said container externally of said heating chamber, said at least one tube communicating with said conduit means to form a closed isolated steam flow path from the interior of said container to said vent opening, and fastening means detachably securing said cap and said inner housing in an assembled condition.
- 11. A vaporizer comprising a liquid container having an upper opening, a top cap positioned on said container overlying said opening, said cap having a steam outlet opening therein and at least one vent opening therein, an inner cap secured at least partially within said top cap and having a steam outlet communicating with said steam outlet opening of said top cap and having a vent communicating with said at least one vent opening, electrodes depending into said container from said inner cap, at least one tube depending from said inner cap and communicating with said vent, an inner housing cooperating with said inner cap to define a steam collection space communicating with said steam outlet and including a depending heating chamber surrounding said electrodes and having a water inlet opening therein communicating with the container, an opening between said steam collection space and the interior of said container, said inner housing including isolated conduit means open to said container externally of said heating chamber, said at least one tube communicating with said conduit means to form a closed isolated steam flow path from the interior of said container, through the steam collection space to said vent, and fastening means detachably securing said top cap, said inner cap and said inner housing in an assembled condition.
- 18. A vaporizer comprising a liquid container having an opening closed by a cover, a heating chamber in said container defining a steam-receiving space and having an aperture through which liquid in said container can enter said chamber, heating means in said chamber, steam outlet means in said cover communicating with said heating chamber through which steam normally produced by said heating means passes, a vent opening in said cover, said heating chamber having an opening located above said aperture, communicating with said steam-receiving space, and leading to the interior of said container outside said chamber, enclosed isolated conduit means extending from said container interior to said vent opening in said cover and passing through said steam-receiving space, excess steam passing through said opening into said container interior, through said conduit means, and out through said vent opening.
