Description

Technical Field

[0001] The present invention generally relates to cooking appliances, and more particularly to small cooking stoves. Background Art

[0002] Ordering food in a restaurant or preparing a hot sandwich at home, especially a breakfast sandwich, is a popular food item. A hot sandwich may include a plurality of different independent filling portions arranged in layers between two slices of bread. For example, the filling portions of a typical breakfast sandwich may include ham, bacon, sausage patties, vegetables, cheese, eggs, etc. and various combinations thereof, and the filling portions for hot sandwiches vary widely.

[0003] Preparing a hot sandwich at home, especially a breakfast sandwich, can be a complex and time-consuming task. Multiple utensils are required to separately prepare the independent portions and then combine these independent portions into a complete sandwich. For example, an oven can be used to bake an English muffin and a microwave oven can be used to heat pre-cooked ham. A cooking pan or skillet appliance on a cooktop appliance may be required to cook eggs. Using multiple utensils makes it difficult to coordinate the preparation of the independent portions to ensure that all the independent portions are completed and ready at approximately the same time, thereby forming a complete sandwich in which all the portions are properly cooked and at the desired temperature. In addition, the process of cleaning multiple utensils adds additional time, frustration, and complexity to the home cooking process.

[0004] So far, no way has been found to create a kitchen appliance capable of preparing a hot sandwich such that all the portions are heated, baked, and / or cooked to present a fully assembled sandwich to the user. The appliance disclosed below achieves the above and other objects and at least overcomes the above drawbacks of traditional kitchen appliances and methods for preparing hot sandwiches. Summary of the Invention
