Abstract

A speed cooking oven is disclosed comprising a cooking cavity, a controller, thermal heating source, blower assembly, air directing means and a vent assembly. Hot air 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.

Claims

1. A speed cooking oven for cooking a food product by hot gas, comprising:

(a) a housing defining a cooking chamber having a top, bottom, right side wall, left side wall and back wall;

(b) a conduit means associated with the cooking chamber, said conduit means providing for the circulation of the gas to and from the cooking chamber;

(c) a flow means for causing circulation of the gas;

(d) a thermal means for heating the gas;

(e) a control means for controlling the gas flow;

(f) a damper means for adjusting the amount of gas delivered via said conduit means to said gas directing means;

(g) a first gas directing means associated with the conduit means and disposed above the food product; and

(h) a second gas directing means associated with the conduit means disposed above the food product, wherein the first and second gas directing means are configured to cause the gas from the first gas directing means to collide with the gas from the second gas directing means upon the upper surface of the food product.

2. A speed cooking oven for cooking a food product by hot gas, comprising:

(a) a housing defining a cooking chamber having a top wall, bottom wall, right side wall, left side wall and back wall;

(b) a conduit means associated with the cooking chamber, said conduit means providing for the circulation of the gas to and from the cooking chamber;

(c) flow means for causing circulation of the gas;

(d) thermal means for heating the gas;

(e) control means for controlling the gas;

(f) a damper means for adjusting the amount of gas delivered via said conduit means to said gas directing means;

(g) a first gas directing means associated with the conduit means and disposed below the food product; and

(h) a second gas directing means associated with the conduit means disposed below the food product, wherein the first and second gas directing means are configured to cause the gas from the first gas directing means to collide with the gas from the second gas directing means upon the bottom surface of the food product.

3. A speed cooking oven for cooking a food product by hot gas, comprising:

(a) a housing defining a cooking chamber having a top wall, bottom wall, right side wall, left side wall and back wall;

(b) a conduit means associated with the cooking chamber, said conduit means providing for the circulation of the gas to and from the cooking chamber;

(c) a flow means for causing circulation of the gas;

(d) a thermal means for heating the gas;

(e) a control means for controlling the gas;

(f) a damper means for adjusting the amount of gas delivered via said conduit means to said gas directing means;

(g) a first gas directing means associated with the conduit means and disposed above the food product;

(h) a second gas directing means associated with the conduit means disposed above the food product, wherein the first and second gas directing means are configured to cause the gas from the first gas directing means to collide with the gas from the second gas directing means upon the upper surface of the food product;

(i) a third gas directing means associated with the conduit means and disposed below the food product; and

(j) a fourth gas directing means associated with the conduit means disposed below the food product, wherein the third and fourth gas directing means are configured to cause the gas from the third gas directing means to collide with the gas from the fourth gas directing means upon the bottom surface of the food product.
