The present disclosure relates generally to appliances, and more particularly to small cooking appliances.
Hot sandwiches, particularly breakfast sandwiches, are popular food items, whether ordered in a restaurant or made at home. Hot sandwiches may include multiple different individual filling components layered between two pieces of bread. For example, a hot breakfast sandwich can be made from English muffins, bagels, pancakes, waffles, or the like. The filling components for hot sandwiches vary greatly. Typical filling components of a breakfast sandwich could include ham, bacon, Canadian bacon, sausage patties, vegetables, cheese, egg, and the like and various combinations thereof.
Making hot sandwiches at home, particularly breakfast sandwiches, can be a complicated and time-consuming task. Multiple appliances must be used to separately prepare the individual components, which are then assembled into a complete sandwich. For example, a toaster may be used to toast the English muffin and a microwave may be used to heat pre-cooked ham. A skillet or griddle appliance or the same on a stovetop appliance might be required to cook the egg. The use of multiple appliances causes difficulty coordinating the preparation of the individual components to ensure that all the individual components are done and ready at about the same time, thereby resulting in a complete sandwich in which all components are properly cooked and at desired temperatures. Moreover, the process of cleaning the various appliances adds additional time, frustration, and complexity to the home cooking process.
It has heretofore not been discovered how to create a kitchen appliance that is capable of preparing a hot sandwich whereby all the components are heated, toasted, and/or cooked so that a fully assembled sandwich is presented to a user. The appliance of the following disclosure accomplishes the above and other objectives and overcomes at least the above-described disadvantages of conventional kitchen appliances and methods of making hot sandwiches.

The ring assembly of the illustrated embodiment comprises top ring 20, bottom ring 22, and center cooking plate 24. In an embodiment illustrated herein, top ring 20 and bottom ring 22 are movably attached to each other (see
In one embodiment, top ring 20 and bottom ring 22 are together selectively movably attached to bottom housing 14. This configuration enables top ring 20 to be movable between a closed position (see
In an alternative embodiment, the top ring and the bottom ring may not be movably attached to each other but only to the bottom housing. In the alternative embodiment discussed above, in which the ring assembly is not attached to appliance 10, the top and bottom rings would not be movably attached to the bottom housing. In such an embodiment, the top and bottom rings may be movably attached to each other, may be pivotably attached to each other, may be attached to each other is any other suitable manner, or may be in contact but otherwise not be attached to each other at all. In such an embodiment in which the top and bottom rings are not attached to each other or to the bottom housing, the top ring may be stackable on the bottom ring. Appropriate guides or other structure may be present on the top and/or bottom rings to help maintain the rings in such a stacked configuration.
Center cooking plate 24 is movable between a closed position and an open position. Center cooking plate's closed position is most broadly defined by a position wherein center cooking plate 24 overlaps the circumference of at least one of top ring 20 or bottom ring 22 (see
Top and bottom cooking surfaces 16, 18 selectively form, along with the ring assembly, top and bottom cooking cavities. The top cooking cavity is formed by the top cooking surface 16, the top ring 20, and the center cooking plate 24 when each are properly positioned (see, e.g.,
Appliance 10 may comprise a handle 30 affixed to top housing 12, a handle 32 affixed to top ring 20, and a handle 34 affixed to bottom ring 22. These separate and independent handles enable a user to independently move the top housing, the top ring, and the bottom ring. Appliance 10 may further comprise a handle 36 affixed to center cooking plate 24 to enable a user to slide or pivot center cooking plate 24 relative to the top or bottom rings 20, 22. One or more of the handles 30, 32, 34, 36 may have one or more through-holes 38 defined therein to inhibit heat transfer to the portion of the handle that a user would grasp. Handles 30, 32, 34, 36 may also comprise a hollow construction to further insulate the handles. Latches (not illustrated) or other types of locking mechanisms may be included (such as in conjunction with top housing handle 30) to keep the appliance in a fully closed position during cooking.
Appliance 10 comprises display/control panel 40. Display/control panel 40 may comprise any desired combination of user input elements (e.g., buttons, switches, knobs, dials, etc.) to enable a user to control operation of appliance 10 and/or display elements (e.g., lights, alphanumeric displays, etc.) to provide information to a user. For example, display/control panel 40 may comprise a “power” light and a “preheat” light. As another example, display/control panel 40 may comprise any suitable means for turning the appliance on and off (e.g., a simple on/off switch) and/or for controlling the cooking time (e.g., a timed on/off switch). Alternatively, on/off switches and the like may be omitted and the appliance may be turned on and off simply by plugging in and unplugging the appliance from a power source. Further, display/control panel 40 may comprise a timer (electromechanical or digital) that simply times the cooking of the food item but does not control power to the appliance.
The ring assembly of appliance 10 may comprise at least one spacer element to maintain a desired spacing between the top and bottom rings. The desired spacing corresponds to the thickness of the center cooking plate. The spacing should be large enough to enable the center cooking plate to readily slide or pivot between its open position and its closed position while the top and bottom rings are in their respective closed positions and small enough to reduce the likelihood of food items (especially uncooked egg) inadvertently escaping when the center cooking plate is in its closed position. Specifically, as illustrated in
The ring assembly of appliance 10 may comprise a closed position stop guide to ensure that, when the center cooking plate is in its closed position, the center cooking plate properly overlaps a bottom open end of the top ring and a top open end of the bottom ring. Thus, the top and bottom cooking cavities are appropriately defined, and thus the likelihood of food items, such as uncooked egg or the like, inadvertently escaping when the center cooking plate is in its closed position is reduced. Spacer element top portion 70 can function as the closed position stop guide. For example, handle 36 of the center cooking plate 24 could contact spacer element top portion 70 when center cooking plate 24 is in its fully closed position.
In an embodiment of the disclosure in which heating elements are provided in both the top and bottom housings, the top heating element will conductively heat the top cooking surface and the bottom heating element will conductively heat the bottom cooking surface. When the top housing is in a closed position, contact is maintained between (i) the bottom cooking surface and the bottom ring, (ii) the bottom ring and the center cooking plate, (iii) the center cooking plate and the top ring, and (iv) the top ring and the top cooking surface. As such, conductive heat transfer occurs from the top cooking surface and/or the bottom cooking surface to the top ring, the bottom ring, and the center cooking plate.
In an embodiment of the disclosure in which heating elements are provided in both the top and bottom housings, in addition to a power cord that goes from the bottom housing to a wall electrical outlet (not illustrated) to provide electrical power to the appliance, power cord 82 routes power from the bottom housing to the top housing to supply the top heating element.

Alternatively, either or both of top cooking surface 16 and bottom cooking surface 18 may comprise one or more channels, dimples, or any other suitable indentations to engage, respectively, with one or more corresponding ridges, rims, bumps, or other suitable projection(s) on bottom ring 22 and/or top ring 20. Such structure for engagement between the ring assembly and top and bottom cooking surfaces 16, 18 may be particularly desirable in an embodiment in which, as described above, the ring assembly is not attached to appliance 10 but merely rests on lower cooking surface 18. Further, either or both of top cooking surface 16 and bottom cooking surface 18 may be ridged or ribbed rather than planar.
The embodiments of the appliance illustrated herein has a generally round horizontal cross-sectional shape, which is well suited for preparing sandwiches made using round bread, such as English muffins and bagels. However, alternative embodiments of the appliance may have any other desirable horizontal cross-sectional shape. For example, one alternative embodiment of the appliance may have a generally square horizontal cross-sectional shape. Another alternative embodiment of the appliance may have a horizontal cross-sectional shape that resembles a standard slice of bread (i.e., three straight sides and one convex side).
A method for cooking a food item comprising a plurality of layers will now be described with reference to
When the appliance is preheated, top housing 12 and top ring 20 are raised to their open positions and bottom ring 22 is kept closed, as illustrated in
Once center cooking plate 24 is in the closed position and top ring 20 is lowered, additional food layers may then be placed into top ring 20 such that the first additional food layer sits directly on the center cooking plate. Advantageously, because the center cooking plate is heated, this food layer may comprise a food item that requires cooking or heating, although such a food layer is not required. For example, an uncooked egg may be placed on center cooking plate 24. The heated center cooking plate can appropriately cook or heat the egg to food safe temperatures. One or more additional layers of food items may then be placed on top of the food layer that sits directly on center cooking plate 24. The top layer (i.e., the last layer to be placed into the top ring) may be, for example, the other half of the English muffin.
After all of the desired layers are placed into top ring 20, top housing 12 is lowered into its closed position, as illustrated in
After sufficient time has elapsed, center cooking plate 24 is moved to its open position in which the movable cooking plate 24 is no longer separating the top cooking cavity from the bottom cooking cavity, as illustrated in

In embodiments of the disclosure described above, one or more additional layers of food items may then be placed on top of the food layer that has been placed directly on the center cooking plate. The food layer that has been placed directly on the center cooking plate is often an uncooked egg. A user may not desire to place a food layer directly on top of an uncooked egg, especially if the food layer to be placed on top of the uncooked egg is a bread item (e.g., the top half of an English muffin). Such a bread item placed directly on top of an uncooked egg may absorb some of the uncooked egg prior to cooking, which may cause the cooked sandwich to have undesirable properties (e.g., texture). For this reason, it may be desirable to elevate one or more food layers (such as a bread item) to keep the elevated item(s) physically separated from the item below until the cooking is complete and the sandwich is ready to be assembled.
