Abstract
A burner for a glass top stove includes a heating element, and a reflector. The reflector is shaped to reflect heat and light emitted down and to the sides of the heater back up to the glass top of the burner. The reflector is shaped to form multiple images of the heater on the glass plate. This ensures uniform heating of the glass plate. It also causes a user to believe that there are more heaters than are actually mounted on the burner.
Claims18
A cooking apparatus, comprising:
- a plate upon configured to receive thereon an object to be heated;
- a ring shaped heater mounted under the plate;
- and
- a reflector positioned at least partially below the ring shaped heater so as to reflect heat and light emitted from the ring shaped heater toward the plate, wherein the reflector comprises
- a bottom wall;
- an outer wall that extends upward and outward from the bottom wall;
- and
- a dome that projects upward from a central portion of the bottom wall towards a center of the ring shaped heater such that the dome forms a curved convex shape at the central portion of the bottom wall, with an upwardly curved top of the dome positioned above a top surface of the heater, wherein a center of curvature of the outer wall and a center of curvature of the dome are each located at an outer side of the reflector, the outer side of the reflector being opposite from a side of the reflector facing the heater, and wherein a curvature of the outer wall and a side and top of the dome cause multiple images of the ring shaped heater to be formed on the plate.
