Abstract
Abstract A steam generating device comprising a metallic evaporation body of desired shape, such as a dish-like shape, a cylindrical shape and so on; and a thin layer provided on the surface of the body, the layer having a rough surface and a water absorption ability. In use, the device is heated and, then, a little water is intermittently supplied on the thin layer, so that the water is instantaneously evaporated.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
42 words
A device for generating steam comprising; a metallic evaporation body of desired shape; and a thin layer provided on the surface of said body, the layer comprising a carbohydrate material, said material being coated on said surface and burned into the surface.
Claim 2
Independent Claim
42 words
A device for generating steam comprising; a metallic evaporation body of desired shape; and a thin layer provided on the surface of said body, the layer comprising a carbohydrate material, said material being coated on said surface and burned into the surface.
Claim 3
Dependent Claim
29 words
A device as set forth in claim 1 further including heater means for heating said body and layer; and means for intermittently supplying a little water to said layer.
Claim 4
Dependent Claim
67 words
A device as set forth in claim 2 in which said water supplying means includes a water reservoir; and a normally closed passage which is adapted to introduce the water in said reservoir onto said layer, the water in said reservoir being pressurized whereby upon opening said passage the water is supplied onto said layer through said passage regardless of the inclination of said steam generating device.
Claim 5
Dependent Claim
50 words
A device as set forth in claim 3 in which said water supplying means is adapted to intermittently supply about 0.5 cc of water per one time and said heater means is adapted to heat said body so that said layer provided thereon becomes about 145° C - 160° C.
Claim 6
Dependent Claim
35 words
A device as set forth in claim 3 in which said means for supplying water is made from flexible material and is compressed by compression means so that the water in the reservoir is pressurized.
Claim 7
Dependent Claim
17 words
A device as set forth in claim 5 in which said compression means is a compressed spring.
