Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
146 words
A portable steam generating apparatus in supplying moist heat for the prepAration of food in an enclosed chamber, comprising in combination a hermetically sealed water and steam chamber having a closeable filling aperture in the upper portion thereof, an electric heating element hermetically mounted within said chamber, means for selectively energizing said heating element for controlled durations of time, and steam emitting means having one end disposed in the upper portion of said water chamber and projecting outward therefrom at an angle above the horizontal, said steam emitting means being elongated and having a plurality of axially aligned apertures, the lower edges of said apertures being positioned above the bottom of said steam emitting means and being located in the lower quadrants when viewed from the outward end of said steam emitting means, to provide a continuous channel for return of condensed steam to said chamber.
Claim 2
Dependent Claim
146 words
A portable steam generating apparatus in supplying moist heat for the prepAration of food in an enclosed chamber, comprising in combination a hermetically sealed water and steam chamber having a closeable filling aperture in the upper portion thereof, an electric heating element hermetically mounted within said chamber, means for selectively energizing said heating element for controlled durations of time, and steam emitting means having one end disposed in the upper portion of said water chamber and projecting outward therefrom at an angle above the horizontal, said steam emitting means being elongated and having a plurality of axially aligned apertures, the lower edges of said apertures being positioned above the bottom of said steam emitting means and being located in the lower quadrants when viewed from the outward end of said steam emitting means, to provide a continuous channel for return of condensed steam to said chamber.
Claim 3
Dependent Claim
58 words
A portable steam generating apparatus as defined in claim 1, including steam actuated switching means responsive to steam pressure in the upper portion of said chamber to de-energize said heating element when the steam pressure exceeds a first predetermined amount, and to permit energization of said heating element when the steam pressure is below a second predetermined amount.
Claim 4
Dependent Claim
62 words
A portable steam generating apparatus as defined in claim 1, wherein said steam emitting means comprises a portion secured to said water chamber and a detachable portion, said portions being connectable by a fluid tight coupling, and said detachable portion containing at least one array of apertures therein and an axially aligned channel portion for conveying condensed steam to said water chamber.
