Abstract
An oven for cooking by hot air impingement includes a housing defining a cooking chamber adapted to receive a food product for cooking, a hot air plenum configured and dimensioned to hold a volume of air and a conduit for providing gaseous communication therebetween. Associated with the plenum is a thermal energy source for heating gas disposed in the plenum.
Claims3
An oven for cooking a food product at least partially by hot gas flow, comprising:
- (A) a housing defining a cooking chamber adapted to receive and hold a food product for cooking;
- (B) a hot gas plenum configured and dimensioned to hold and heat a volume of hot gas;
- (C) conduit means for providing gaseous communication between said cooking chamber and said plenum;
- (D) means for sensing the temperature in said plenum;
- (E) means for sensing the temperature in said cooking chamber;
- and
- (F) control means for selectively and variably causing the flow of hot gas between said plenum and said cooking chamber via said conduit means depending at least in part on said sensed temperature in said plenum and said sensed temperature in said cooking chamber.
