Abstract
A convection oven is provided with a fan for circulating air in the cooking chamber of the oven. The food is held in a food holder which is attached to but spaced from the inside surface of the oven door. Heating elements are at the top and the bottom of the cooking chamber. A flue opening is in the bottom of the cooking chamber and the heating elements are positioned above the lengthwise lower ends of the flue opening for inducing external air around the lower heating elements and the lower surface of the food and food holder. A method is disclosed for introducing external air into the bottom of a convection heating oven, to cool the lower surface of the food in the oven and provide turbulence to the circulating air for enhancing the cooking of the food.
Claims18
A convection oven having a cooking chamber, the cooking chamber having a back wall, front wall, opposite left and right end walls, a top wall and a bottom wall;
- a food holder in the cooking chamber, the food holder having a bottom;
- upper and lower heating elements in the cooking chamber spaced respectively above and below the food holder;
- a fan for circulating air in the cooking chamber around the food holder and the heating elements;
- and
- a flue opening in the bottom wall having opposite upper lengthwise edges, opposite upper widthwise edges, opposite lower lengthwise edges, and opposite lower widthwise edges for admitting external air into the cooking chamber adjacent to the lower heating elements, the lower heating elements lying parallel and adjacent to the upper lengthwise edges.
A convection oven comprising:
- a cooking chamber, the cooking chamber having a back wall, front wall, opposite left and right end walls, a top wall and a bottom wall;
- a food holder in the cooking chamber;
- upper and lower heating elements in the cooking chamber spaced respectively above and below the food holder;
- a fan for circulating air in the cooking chamber around the food holder and the heating elements;
- and
- a flue opening in the bottom wall for admitting external air into the cooking chamber adjacent to the lower heating elements, the lower heating elements lying parallel and adjacent to opposite lower lengthwise edges of the flue opening.
A method of enhancing the cooking of food in a food holder located in a cooking chamber of a convection oven, the cooking chamber having a bottom wall, comprising:
- internally heating the cooking chamber above and below the food holder;
- circulating air around the cooking chamber to enhance the heating of the food in the food holder;
- introducing external air into the cooking chamber through a flue opening in the bottom wall below the food holder to increase turbulence of the air below the food holder and reduce the heat below the food holder.
A convection oven comprising:
- a cooking chamber, the cooking chamber having a back wall, front wall, opposite left and right end walls, a top wall and a bottom wall;
- a food holder in the cooking chamber;
- upper and lower heating elements in the cooking chamber spaced respectively above and below the food holder;
- a fan for circulating air in the cooking chamber around the food holder and the heating elements;
- and
- a flue opening in the bottom wall for admitting external air into the cooking chamber adjacent to the lower heating elements, the flue opening extending substantially the full length of the food holder.
