Abstract
An appliance of the preparation of meat or similar products is disclosed, and which includes an outer casing, and an inner casing which is adapted to receive the food product. An air venting system is provided by which the inner casing may be closed and air tight, or opened so as to be in communication wit the outside air. A circulating fan and a heating element are positioned in the inner casing, and a control system is provided by which the appliance may be selectively operated in a cooking mode wherein the air venting system is closed, a grilling mode wherein the air venting system is open, and a hot maintenance mode wherein the air venting system is closed and the circulating fan and heating elements are operated at relatively low levels.
Claims9
An appliance for the preparation of meat or other food products, comprising
- an outer casing,
- an inner casing positioned within said outer casing so as to define a space therebetween,
- air venting means which is movable between a closed position wherein said inner casing is substantially air tight and an open position wherein the interior of said inner casing is in communication with the environment outside of said outer casing,
- means positioned in said inner casing for supporting a food product,
- an air circulating fan rotatably mounted in said inner casing, and a drive motor for rotating said air circulating fan,
- a heating element mounted in said inner casing, and
- control mans for selectively
- (1) moving said air venting means between said closed and open positions;
- (2) controlling the operating speed of said drive motor between at least two predetermined operating speeds;
- and
- (3) controlling the temperature of said heating means between at least two predetermined operating temperatures.
An appliance for the preparation of meat or other food products, comprising
- an otuer casing,
- an inner casing positioned within said outer casing so as to define a space therebetween, and with said inner casing including a traverse wall which divides the interior of said inner casing into a first portion, and a second portion, and wherein said transverse wall includes openings which permit air of circulate between said first and second portions,
- air venting means which is movable between a closed position wherein said inner casing is substantially air tight and an open position wherein the interior of said inner casing is in communication with the environment outside of said outer casing, said air venting mean comprising in inlet opening means nd separate air outlet opening means, and an exhaust fan for drawing air through said inner casing when said air venting means is in said open position,
- means positioned in said first portion of said inner casing or supporting a food product,
- an air circulating fan rotatably mounted in said second potion of said inner casing, and a drive motor for rotating said air circuiting fan,
- a cooling fan rotatably mounted in said space between said outer casing and said inner casing, and means of operatively connecting said cooling fan to said drive motor such that said air circulating fan and said cooling fan are commonly driven,
- a heating element mounted in said second portion of said inner casing, and
- control means or selectively
- (1) moving said air venting means between said closed an open positions;
- (2) controlling the operating speed of said drive motor between at least two predetermined operating speeds;
- (3) controlling the temperature of said heating means between at least two predetermined operating temperatures, and
- (4) controlling the operation of said exhaust fan.
