Abstract
Abstract A vapor generating device including a housing having an open top and closed bottom with a cleaning solvent therein. The housing is provided with first heat means in the bottom thereof to boil the solvent and cooling means in the top thereof to condense the solvent and prevent the solvent from escaping from the housing. A second heat means is provided in the bottom of the housing operable whenever a change in energy requirement within the housing is necessary. The vapor generating device is particularly useful as a cleaning device.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
113 words
A vapor generating device for immersing objects to be cleaned in a vaporizing solvent comprising: A housing having at least one container therein for vaporizing and condensing the vaporizing solvent, said container having an open top and a closed bottom with cooling means in an upper portion thereof, the container having a heat means in a lower portion thereof operable in response to a change in energy requirements in said container, said heat means includes a first heat means and a second heating means, the first heating means having a fixed heat input and the second heating means having a variable heat input actuated by a sensing device disposed in said upper portion.
Claim 2
Dependent Claim
113 words
A vapor generating device for immersing objects to be cleaned in a vaporizing solvent comprising: A housing having at least one container therein for vaporizing and condensing the vaporizing solvent, said container having an open top and a closed bottom with cooling means in an upper portion thereof, the container having a heat means in a lower portion thereof operable in response to a change in energy requirements in said container, said heat means includes a first heat means and a second heating means, the first heating means having a fixed heat input and the second heating means having a variable heat input actuated by a sensing device disposed in said upper portion.
Claim 3
Dependent Claim
29 words
The device of claim 1 wherein said container includes temperature sensing means at a preselected position in the upper portion thereof in actuating communication with said second heating means.
Claim 4
Dependent Claim
35 words
