Multifunctional griddle
View Patent ↗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.
1. A multifunctional griddle comprising:
an upper housing section and a lower housing section interconnected by a hinge assembly, wherein said upper and said lower housing sections include upper and lower handles disposed in interlocking engagement;
an upper heater assembly including a heating plate having an integrated heating element, wherein said upper heating assembly is disposed within said upper housing section, and a lower heater assembly including a heating plate having an integrated heating element disposed within said lower housing section;
a temperature controlling means electrically interconnected to said upper heater assembly and said lower heater assembly, said temperature controlling means also being electrically connected to a power source; and
a plurality of interchangeable cooking plates having a cooking surface on a first side thereof and a flat heat transfer surface on a second side thereof, said cooking plates being disposed in face-to-face relation with said upper heater assembly and said lower heater assembly respectively to provide a sliding interface therebetween to facilitate interchangeability of said cooking plates, each of said interchangeable cooking plates including plate retaining means for securing said cooking plates in position, wherein said plate retaining means include an integral clasp formed on a front edge thereof for sliding engagement with a mating clip formed on said upper and lower handles, said clasp interlocking with said clip to retain said cooking plates in position during operation.
2. The multifunctional griddle of claim 1 wherein said plate retaining means further includes a retaining ledge integrally formed along a back edge of said cooking plates for sliding engagement with a mating plate retainer formed on each half-section of said hinge assembly to retain said cooking plates in position during operation.
3. The multifunctional griddle of claim 1 wherein said plurality of interchangeable cooking plates include at least one waffle-iron surface and at least one grilling surface.
4. The multifunctional griddle of claim 3 wherein said heating plates and said cooking plates are fabricated from materials having a high coefficient of heat conductivity.
5. The multifunctional griddle of claim 1 wherein said heating elements are constructed of stainless steel tubing wherein a resistance heater wire is enclosed.
6. The multifunctional griddle of claim 1 wherein said temperature controlling means includes a rheostatic temperature controller.
7. The multifunctional griddle of claim 1 wherein said upper and lower housing sections are fabricated from a heat-resistant material.
