Speed cooking oven with radiant mode

Abstract

A speed cooking with gas flow by-pass for radiant mode. A speed cooking oven with radiant mode is disclosed comprising a cooking cavity, a controller, thermal heating source, blower assembly, air directing means, a vent assembly and a gas by-pass system. Hot gas is circulated by the blower motor assembly into the oven cavity where the hot air is directed in a manner wherein a conflicting, colliding turbulent gas flow is directed at a food product providing for the rapid cooking of food products. Alternatively, gas may be diverted around the cooking cavity and maintained at the same temperature, lower temperature or elevated temperature as compared to the cooking cavity without having a direct effect on the food product being cooked.

1 . An oven for cooking a food product by hot gas, comprising: 
 a housing;    a cooking chamber disposed within the housing;    a thermal means for heating the gas;    a gas circulating chamber disposed between the housing and the cooking chamber;    a flow means for circulating the gas through the gas circulating chamber, over the thermal means, through the cooking chamber, and back through the gas circulating chamber; and    a by-pass system for reducing the flow of gas into the cooking chamber, the by-pass system being operable between a bypass mode in the flow of gas through the cooking chamber is reduced, and a non-bypass mode in which the flow of gas through the cooking chamber is not reduced.    
     
     
         2 . The oven according to  claim 1 , wherein the by-pass system comprises: 
 a first door in the wall of the gas circulating chamber, the first door being operable between and opened position and a closed position;    a second door in the cooking chamber, the second door being operable between and opened position and a closed position; and    a conduit between the first door and the second door;    wherein the bypass mode is achieved when the first door is in the opened position and the second door is in the closed position, and the non-bypass mode is achieved when the first door is in the closed position and the second door is in the opened position.    
     
     
         3 . The oven according to  claim 2 , wherein the first door and the second door are each sliding doors.  
     
     
         4 . The oven according to  claim 1 , wherein the cooking chamber is radiantly heated by the hot gas flowing through the gas circulating chamber when the by-pass system is in the by-pass mode.  
     
     
         5 . The oven according to  claim 1 , wherein the second door is adjacent the thermal means.  
     
     
         6 . The oven according to  claim 1 , wherein the first door is disposed in a lower portion of a back wall of the gas circulating chamber, and the second door is disposed in a top wall of the cooking chamber.  
     
     
         7 . The oven according to  claim 1 , further comprising: 
 a control system for selectively activating the by-pass system.    
     
     
         8 . The oven according to  claim 1 , further comprising: 
 a control system for activating the by-pass system according to a preprogrammed schedule.    
     
     
         9 . The oven according to  claim 1 , further comprising: 
 a microwave cooking subsystem for sending microwave energy into the cooking chamber.    
     
     
         10 . The oven according to  claim 1 , further comprising: 
 a speed cooking subsystem for speed cooking the food product.
