Abstract
A waffle iron comprises textured upper, lower, and perimeter heatable plates that can be assembled to create a cavity into which batter and other prepared ingredients are dispensed to cook a waffle having sufficient depth to feature a waffle pattern along its top and bottom faces as well as along its thickness and to fully contain within its batter separate, prepared ingredients which are enclosed within the waffle to make a single unit and can be eaten in its entirety by hand without having to fold the waffle around those ingredients, sandwich those ingredients between waffles, or use any other means to keep the waffle from separating from the ingredients. The waffle can be visually inspected for doneness during the cooking process or removed from the assembled unit once cooked by separating the individual plates. Electronic means may also be employed to monitor or alert of doneness.

DESCRIPTION OF EMBODIMENT
(31) In one embodiment, a device is provided to cook the waffle over a flame or electric burner. FIG. 1 is an exploded diagram showing a bottom plate 1 with waffle features along a bottom surface 2 that include a top face 3 and inclined vertical faces 4. The bottom plate includes cross members 5 and 6; an outside cooking surface 7 and side wall 8. The bottom plate has a side plate support lip which comprises a flat top face 9 and an inclined vertical face 10. A first side plate insert 11 has a top edge 12 and a bottom edge 13 that rests on the flat top face of the bottom plate support lip 9. The first side plate insert has an outside surface 14 and an inside surface 15 with a plurality of waffle features 16. The side plate waffle features may match the size and shape of the bottom plate waffle features or may have a different shape or size. In this example the top plate 17 is identical to the bottom plate 1 and both side plates 11, 18 are identical, but the top and bottom surfaces of these could differ or include additional surfaces that would allow for a locking assembly, for example. In this example, the diameter of the side plate support lip 19 and the inner diameter of the side plate 20 are 5; the diameter of the bottom plate outside surface 7 is 5; the diameter of the side plate outside surface 14 is 5; the height of the inclined vertical face of the side plate support lip 10 is ; the height of the side wall 8 is 1. Other sizes or shapes may be used.
(32) The plates 1, 11, 17, 18 are preferably type III anodized aluminum alloy such as 6061 with a food-safe non-stick coating applied to the surfaces in contact with food. FIG. 2 is an example of this embodiment machined from anodized aluminum with a polytetrafluoroethylene coating on the food contact surfaces. The handle 21 may be of the same material as the bottom plate and can be used to flip the device when cooking. The plates 1, 11, 17, 18 could also be fabricated from a stainless steel alloy, in which case no non-stick coating would typically be applied.
(33) FIGS. 3-4 depict the device's operation. In FIG. 3, the plates 1, 17 rest flat side down on top of a heating surface. Next, each side plate 11, 18 is placed on the flat top of the bottom plate support lip 9 to create a cavity 22 into which batter and ingredients are dispensed. The heating surface heats the plates 1, 11, 17, 18 to a sufficient temperature to cook the batter. Batter (not shown) is then poured into the bottom plate to where it just covers the waffle features. Next, the filling ingredients (not shown) are placed into the batter. The cavity 22 is filled when the remaining batter is poured over the filling to just below the top of the side plates 17, 18. As shown in FIG. 4, the unit is closed by placing the top plate 17 atop the side plates 17, 18. The entire unit is then flipped to allow for an even distribution of batter inside the cavity 22 such that the bottom plate 1 rests atop the side plates 17, 18 with its flat surface opposite the heating surface. During the cooking process, the entire unit may be flipped to cook the batter sufficiently on both sides. Either plate not resting on the heating surface may be removed during the cooking process to visually inspect doneness. The cooked waffle is removed from the unit by individually separating each plate 1, 11, 17, 18.
DESCRIPTION OF EMBODIMENT
(34) FIG. 5 is a front perspective of a second embodiment where the device is heated directly from an electrical source. This electrically-heated waffle maker comprises a bottom plate 23 with waffle features fixed to the bottom of a rear plate 24 with waffle features along its front surface; a top plate 25 with waffle features; and two side plates 26, 27 with waffle features. The top plate 25 is attached to the top face of the rear plate 24 by a horizontally-oriented hinge 28. The side plates 26, 27 are attached to the side surfaces of the rear plate 23 by vertically-oriented hinges 29, 30. The bottom and top plates 23, 25 have cooperating bottom and top retaining structures 31, b, respectively, which are supported by a front support 33 extending upwardly from a bottom base control unit 34 to support the forward ends of the plates 23, 25. The rear plate 24 is attached to a rotating bracket 35 which is mounted to a rear support 36, also extending upwardly from the bottom base control unit 34 to support the rearward ends of plates 23, 25. The front support 33 has a scoop-shaped top 37 into which the bottom retaining structure 31 rests. A handle arm 38 with a plastic end 39 protrudes from the top retaining structure 32. The handle arm 38 bends downward away from the front support 33. The bottom base control unit 34 encloses the electronics (not shown) to regulate heat to the plates 23, 24, 25, 26, 27; indicate power and heating status; and toggle power to the device. The bottom base control unit 34 provides mounting support for a knob 40 to regulate the heat to the bottom and top plates 23, 25; a knob 41 to regulate the heat to the side plates 26, 27; a pilot light 42 indicating whether or not is on, a pilot light 43 indicating whether or not the device is heated and ready for use; and a toggling power switch 44. The temperature knobs 40, 41 can be moved to three preset positions (LOW, MEDIUM, HIGH) allowing the bottom/top portions of the batter to cook at a different rate than the batter along the perimeter.
(35) The plates 23, 24, 25, 26, 27 are preferably cast aluminum which are heated when a voltage is applied thereto such as through internal electrical leads (not shown) and may be enclosed in a shell around the surfaces that do not have waffle features by a non-conductive material. The exposed metal surfaces are treated with a polytetrafluoroethylene coating.
(36) FIGS. 6, 7 depict the operation of the electrically-heated waffle maker. The side plates 26, 27 rotate to a closed position, making a cavity 45 into which batter (not shown) is poured to just where it covers the top of the waffle features of the bottom plate 23. The filling ingredients (not shown) are then placed onto the batter and then the remaining batter is poured up to top surface of the side plates 26, 27. The top plate 25 rotates down along the horizontal axis aligned with the hinge 28 to a closed position resting on the top surface of the side plates 26, 27. A cooking cycle of the waffle maker is initiated when the closed unit 46 is rotated 180 along the rotating bracket 35 using the handle arm 38 and plastic end 39. An alarm (not shown) housed in the bottom base control unit 34 sounds at the end of the cooking cycle. The alarm is stopped when the closed assembly is rotated back 180 to its original position. The waffle is removed from the device lifting the top plate 25 using the handle arm 38 which automatically rotates side plates 26, 27 along hinges 29, 30.
DESCRIPTION OF EMBODIMENT

FIG. 8 is an exploded diagram showing a bottom assembly 47 comprised of a bottom plate 48 and a handle 49. The bottom plate has waffle features along a bottom surface 50 that include a top face 51 and inclined vertical faces 52. The bottom plate includes cross members 53 and 54; an outside cooking surface 55 and side wall 56. The bottom plate has a side plate insert support lip which comprises a flat top face 57 and an inclined vertical face 58.
(38) A scissor assembly 59 comprises two side plate inserts 60, 61 which attach to handles 62, 63 respectively and rotate along hinge 64. A first side plate insert 60 has a top edge 65 and a bottom edge 66 that rest on the flat top face of side plate insert support lip 57 of the bottom plate. The first side plate insert has an outside surface 67 and an inside surface 68 with a plurality of waffle features 69. The side plate insert waffle features may match the size and shape of the bottom plate waffle features or may have a different shape or size.
(39) In this example the top assembly 70 is identical to the bottom assembly 47 and both side plate inserts 60, 61 are identical, but the top and bottom surfaces of these could differ or include additional surfaces. In this example, the diameter of the side plate support lip 73 and the inner diameter of the side plate 74 are 5; the diameter of the bottom plate outside surface 55 is 5; the diameter of the side plate outside surface 67 is 5; the height of the inclined vertical face of the side plate support lip 58 is ; the height of the side wall 56 is 1. Other sizes or shapes may be used.
(40) The plates 48, 71, 60, 61 are preferably an aluminum alloy such as A380 with a type III anodized finish or a food-safe non-stick coating applied to any of its surfaces. The handles 49, 72 may be of the same or a different material than that of the bottom plate. The plates 48, 71, 60, 61 could also be fabricated from a stainless steel alloy, in which case no non-stick coating would typically be applied.
(41) FIG. 9 is an example of this embodiment machined from aluminum with a polytetrafluoroethylene coating on the plate surfaces 48, 71, 60, 61 and handles 49, 72, 62, 63 machined from a stainless steel alloy.
(42) FIGS. 10-12 depict the device's operation. In FIG. 10, the assemblies 47, 70 rests flat side down on top of a heating surface. Next, the scissor assembly 59 is placed on the flat top of the bottom plate support lip 57 to create a cavity 75 into which batter and ingredients are dispensed. The heating surface heats plates 48, 71, 60, 61 to a sufficient temperature to cook the batter. Batter (not shown) is then poured along the bottom surface 50 of the bottom plate to where it just covers the waffle features. Next, the filling ingredients (not shown) are placed into the batter. The cavity is filled when the remaining batter is then poured over the filling to just below the top of the side plate inserts. As shown in FIG. 11, the unit is closed by placing the top assembly 69 atop the bottom assembly 47. The entire unit is then flipped using handles 49, 72 to allow for an even distribution of batter inside the cavity such that the bottom assembly rests atop the scissor assembly 59 with the flat surface of the bottom plate 47 facing opposite the heating surface. During the cooking process, the entire unit may be flipped to cook the batter sufficiently on both sides.
