Abstract
Abstract A cooking apparatus having surface heater structures supported above a top wall of the housing thereof. The top wall is devoid of conventional heater openings, consequently, the heater structures overlie portions of the top wall and are disposed substantially parallel thereto. Each heater structure is pivotal away from the top wall to facilitate cleaning of the top wall and also to permit removal of a combination heat shield and spacer for cleaning thereof.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
253 words
Cooking apparatus comprising: housing structure including a top wall having a flat, planar extent; at least one heater structure, said heater structure being electrical and having a flat, planar extent; means for supporting said flat, planar extent of said heater structure in a first position substantially parallel to and above said flat, planar extent of said top wall, said support means being adapted to said support said flat, planar extent of said heater structure away from said flat, planar extent of said top wall for facilitating cleaning of said top wall and said heater structure; said heater structure having attached rigid terminal means received in a ball of a universal coupling means consisting of Said ball and complementary elements carried by said top wall; said rigid terminal means being a portion of said support means and including offset portions displaced vertically above said ball for mounting said flat, planar extent of said heater structure above said flat, planar surface of said top wall and said ball when said heating structure is in said substantially parallel position; a heat shield interposed between said heater structure and said top wall and situated above said flat, planar surface of said top wall for minimizing transfer of heat to the latter; and said heat shield comprising a highly reflective surface facing said heater structure and a plurality of spacers facing said top wall for providing, respectively, heat reflection back to said heater structure and an air space to optimize retardation of heat transfer to said top wall.
Claim 2
Dependent Claim
253 words
Cooking apparatus comprising: housing structure including a top wall having a flat, planar extent; at least one heater structure, said heater structure being electrical and having a flat, planar extent; means for supporting said flat, planar extent of said heater structure in a first position substantially parallel to and above said flat, planar extent of said top wall, said support means being adapted to said support said flat, planar extent of said heater structure away from said flat, planar extent of said top wall for facilitating cleaning of said top wall and said heater structure; said heater structure having attached rigid terminal means received in a ball of a universal coupling means consisting of Said ball and complementary elements carried by said top wall; said rigid terminal means being a portion of said support means and including offset portions displaced vertically above said ball for mounting said flat, planar extent of said heater structure above said flat, planar surface of said top wall and said ball when said heating structure is in said substantially parallel position; a heat shield interposed between said heater structure and said top wall and situated above said flat, planar surface of said top wall for minimizing transfer of heat to the latter; and said heat shield comprising a highly reflective surface facing said heater structure and a plurality of spacers facing said top wall for providing, respectively, heat reflection back to said heater structure and an air space to optimize retardation of heat transfer to said top wall.
Claim 3
Dependent Claim
50 words
Structure as specified in claim 1 wherein: said means for supporting said heater structure include a supporting spider means having downwardly depending leg means; said supporting spider means being disposed immediately below said heater structure; and said legs means of said spider means abuttingly supported by said heat shield means.
Claim 4
Dependent Claim
40 words
Structure as specified in claim 2 wherein; said spacers for said heat shield abuttingly contact said flat, planar surface of said top wall for supporting said heat shield, said spider means and at least a portion of said heater structure.
