Abstract
Abstract An electric barbecue grill comprises a cooking vessel and a housing connected centrally thereof. Electric heating means are provided and include a heating elements mechanically mounted on a hollow member of the housing in relative positions for different cooking modes and an electrical cord disposed in the hollow member for protection. A grillwork is provided for supporting a refractory bed adjacent the heating element unit, and electric controls for selectively energizing the heating elements for different cooking modes are disposed in the hollow member to be thermally protected from heat emanating from the heating element unit and the refractory bed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
198 words
An electric barbecue arrangement comprising: cooking vessel means with food support means associated therewith and having an open top defined by an outer lip and a generally centrally disposed portion inwardly of said lip; housing means, including a hollow member connected to said cooking vessel means at said centrally disposed portion; electric heating means, including heating element means mechanically mounted on said hollow member and electrical cord means disposed within said hollow member for protection, said heating element means further including a first, radially inwardly disposed heating element loop for use in a first cooking mode and a second heating element loop disposed radially outwardly of said first heating element loop for use in a second cooking mode; grill work means mounted in said vessel means for supporting a refractory bed adjacent and in heat exchange relationship with said heating element means; and electrical control means for said heating element means disposed in said hollow member to be thermally protected from heat emanating from said heating element means and said refractory bed, said control means including means for selectively energizing the first and second heating element loops whereby to accomplish cooking by either the first or second mode.
