Speed cooking oven
View Patent ↗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 maimer wherein a conflicting, colliding turbulent gas flow is directed at a food product providing for the rapid cooking of food products.
1. A speed cooking oven for cooking a food product by hot gas and microwave energy, said oven comprising:
(a) an oven cavity for containing said food product, said oven cavity having a bottom;
(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 variable speed blower motor for causing circulation of the gas;
(d) a thermal means for heating the gas;
(e) a control means for controlling the gas;
(f) a first gas directing means associated with the conduit means and disposed above the food product and above said bottom of the oven cavity;
(g) a second gas directing means associated with the conduit means disposed above the food product and above said bottom of the oven cavity, 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;
(h) a third gas directing means associated with the conduit means and disposed below the food product and above said bottom of the oven cavity;
(i) a fourth gas directing means associated with the conduit means disposed below the food product and above said bottom of the oven cavity, 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;
(j) microwave waveguides disposed above said bottom of the oven cavity for launching microwave energy into the oven cavity:
(k) wherein said bottom of the oven cavity is smooth and continuous with no heating elements, air ducts or microwave launchers to facilitate easy cleaning of the bottom of the oven cavity.
2. The speed cooking oven according to claim 1 , wherein the gas is circulated at a velocity of about 2000 feet per minute or higher.
3. The speed cooking oven according to claim 1 , wherein the gas is circulated at a velocity of about 6000 feet per minute or lower.
4. The speed cooking oven according to claim 1 , wherein the gas is circulated at a velocity in the range between about 2000 feet per minute and 6000 feet per minute.
5. The speed cooking oven according to claim 1 , wherein the gas is circulated at a velocity of up to 2000 feet per minute.
6. The speed cooking oven according to claim 1 , wherein the gas is circulated at a velocity of 6000 feet per minute or higher.
7. The speed cooking oven according to claim 4 wherein said first and second gas directing means direct gas from opposite sides of the oven cavity.
8. The speed cooking oven according to claim 7 wherein said microwave waveguides launch microwave energy from said opposite sides of the oven cavity.
