  • Patent number: 7960673
    Abstract: A portable electric grill including an exhaust fan for indoor grilling is disclosed. The present grill is constructed to permit its supporting frame to be folded from an open position wherein the horizontally disposed grilling plates are supported by folding leg members to a closed position wherein the grilling plates are folded vertically along with the leg members for convenient portability and storage. The present grill provides heating elements associated with each grilling plate, which permits the grilling plates to be selectively energized. An air filter is disposed within the air intake of the exhaust fan utilizing filter media capable of capturing particulate matter of a size range found in cooking fumes generated by the grill. In an alternative embodiment the present grill is designed to permit operation in an either an unfolded or a folded position and also includes a detachable exhaust fan module for the user's convenience.

  • Patent number: 7335860
    Abstract: A multifunctional griddle having hinged top and bottom heating plate assemblies which receive reversible cooking plates or, alternatively, interchangeable cooking plates for cooking different types of foods such as waffles, pancakes, and hot sandwiches. In one embodiment the reversible cooking plates are nested in face-to-face contact with mating top and bottom heating plates to improve heat transfer to the cooking plates. This is accomplished by forming a mating waffle grid in the heating plates for receiving the waffle iron surfaces of the cooking plates in intermeshing engagement. The intermeshing engagement of the cooking plates with the heating plates also reduces the overall vertical height of the appliance providing a slimmer profile. In an alternative embodiment a set of interchangeable cooking plates is provided having a sliding interface with modified heating plates. In this embodiment the cooking plates are conveniently interchanged to vary the cooking configurations of the appliance.

  • Patent number: 7285751
    Abstract: An automatic electric muffin maker for baking muffins and related foodstuffs is disclosed. The present muffin maker comprises a housing assembly enclosing a bottom heating plate having an integrated heating element and a top heating element for browning (i.e. to scorch slightly in cooking). Advantageously, the heating plate includes a plurality of integrally formed, internally tapered heating wells which receive a mating baking pan having tapered cylindrical mold cups configured to provide complementary surface-to-surface engagement within the heating wells and efficient heat transfer therebetween. The heating elements are electrically interconnected to a heat control thermostat, which regulates the baking cycle. In an alternative embodiment the baking functions are carried out by electronic controls including a timed cooking cycle which changes to a warming mode upon completion.
