Abstract
Abstract A cooking apparatus having an oven, heating means for heating said oven, and support means to support article means in said oven to be effected by the output of the heating means. Electrode means carried by the apparatus and being disposed in the oven, said electrode means being in electrically spaced relation to the article means. A potential differential imposed between the article means and the electrode means to tend to cause soiling particles of the article means to move toward the electrode means during the heating thereof by the heating means to tend to prevent soilage of the cooking apparatus. Means for creating air movement in said oven to direct the soiling particles toward the electrode means and means can be provided to ionize such soiling particles so that the same are more readily attracted by the electrode means.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
127 words
In a cooking apparatus having an oven, heating means for heating said oven, support means to support article means in said oven to be affected by the output of said heating means, the improvement comprising electrode means carried by said apparatus and being disposed in said oven, said electrode means being in electrically spaced relation to said article means, means for imposing a potential differential between said article means and said electrode means to tend to cause soiling particles of said article means to move toward said electrode means during the heating thereof by said heating means to tend to prevent soilage of said cooking apparatus, and means for creating an air movement in said oven that tends to direct said soiling particles toward said electrode means.
Claim 2
Dependent Claim
127 words
In a cooking apparatus having an oven, heating means for heating said oven, support means to support article means in said oven to be affected by the output of said heating means, the improvement comprising electrode means carried by said apparatus and being disposed in said oven, said electrode means being in electrically spaced relation to said article means, means for imposing a potential differential between said article means and said electrode means to tend to cause soiling particles of said article means to move toward said electrode means during the heating thereof by said heating means to tend to prevent soilage of said cooking apparatus, and means for creating an air movement in said oven that tends to direct said soiling particles toward said electrode means.
Claim 3
Dependent Claim
33 words
In a cooking apparatus as set forth in claim 1, said means for imposing a potential differential comprising means imposing one potential on said electrode means and an opposite potential on said particles.
Claim 4
Dependent Claim
24 words
In a cooking apparatus as set forth in claim 1, said heating means comprising an electrical heating means and being disposed in said oven.
Claim 5
Dependent Claim
80 words
In a cooking apparatus as set forth in claim 1, said support means comprising interior surface means of said oven of said cooking apparatus, said article means comprising soilage on said surface means that resulted from previous cooking operations in said oven, said heating means being adapted to elevate the temperature in said oven to a temperature that causes said soilage to leave said surface means in the form of smoke and particles that are attracted by said electrode means.
