Abstract
A countertop oven particularly well suited for preparing convenience foods, such as frozen dinners and hot sandwiches is provided. The oven includes at least one heating and serving tray with heat resistant handles, the tray sliding into slots in the oven side-walls with the handles on the outside so that the heating and serving tray may be removed from the oven and placed directly on a table for serving. In a preferred embodiment of the invention, the oven includes two pairs of slots for receiving two heating and serving trays and includes three heating elements. This heating configuration permits cooking on the two trays in about sixty percent of the time compared to conventional countertop ovens.
Claims20
An oven comprising:
- a steel oven housing including a top wall and an opposed bottom wall, two opposed side walls between the top and bottom walls and a rear wall joined to the top, bottom and side walls for defining an oven cavity;
- a door openably mounted to the front of said housing for providing access to the oven cavity;
- each of the opposed side walls formed with at least one cooperating slot from the front of the oven housing extending towards the rear of the oven;
- heating means for providing heat to the oven cavity;
- and
- a heating and serving tray formed with heat-resistant handles, said tray adapted to slide into the cooperating slots in the oven side walls with the handles remaining on the exterior of the oven housing to facilitate removal of the heated tray and food thereon after heating and wherein the heating and serving tray is a substantially rectangular grill and formed with a metal rod about the perimeter, the metal rod mounted to the heat-resistant handles in the front region and the rear sides of the rod spaced apart from the heat-resistant handles whereby when said tray is inserted into the slots, the side wall is positioned between the rod in the rear section of the tray and the heat-resistant handle.

A countertop oven comprising:
- an inner steel oven housing including a top wall and an opposed bottom wall, two opposed side walls between the top and bottom walls and a rear wall joined to the top, bottom and side walls for defining an oven cavity;
- an outer steel housing including a top wall, two opposed side walls and a rear wall for cooperating with the inner steel housing and spaced apart therefrom for providing an insulated compartment in the back of the oven between the cooperating rear walls and for providing the oven with an insulated top and side walls;
- an oven door openably mounted to the front of oven for selectively providing access to the oven cavity;
- each of the opposed inner and outer side walls formed with two slots from the front of the oven housing extending approximately mid-way to the rear of the oven, the upper slots formed in about the mid-point in height of the side walls and including a downwardly projecting notch and the second lower slots formed in the lower portion of the oven walls spaced apart from the bottom wall;
- three levels of heating elements in the oven cavity, a first upper heating element disposed in the region near the top of the oven cavity, a middle heating element disposed in the region below the upper pair of cooperating slots and a lower heating element disposed below the lower pair of cooperating slots and above the oven bottom;
- a heating and serving tray formed with heat-resistant handles in each pair of cooperating slots, said trays adapted to slide into the cooperating slots in the oven side walls with the handles remaining on the exterior of the outer oven housing to facilitate removal of the heated trays and food thereon after heating;
- and
- heating control circuit means for controlling the oven heating elements positioned in the insulated circuit compartment between the rear walls of the oven.
