Cooking gap control of a cooking apparatus

1. A method of controlling a cooking apparatus, comprising:

initiating a cooking cycle by positioning a food product upon a lower heating plate of a cooking appliance;

identifying an initial thickness of a food product on the lower heating plate of the cooking apparatus;

identifying a predetermined cook time for a food product;

calculating whether a difference exists between an initial gap value corresponding to the initial thickness of the food product and a predefined final gap value;

when the step of calculating the difference between the initial gap value corresponding to the initial thickness of the food product and the predefined final gap value results in a difference being calculated, adjusting the position of the lower heating plate with respect to an upper heating plate to result in compression of the food product disposed upon the lower heating plate until there is no longer a difference between the thickness of the food product and the predefined final gap value, and controlling a rate of ascent of the lower heating plate toward the upper heating plate based on the calculated difference between the initial gap value and the predefined final gap value;

controlling the rate of ascent of the lower heating plate until the predefined gap value is reached; and

sensing that the food product has been cooked based upon a combination of the predetermined final gap value being reached and the predetermined cook time being elapsed.

2. The method of claim 1 , wherein identifying the initial thickness of the food product includes identifying the initial thickness of a first food product and a second food product, the first food product having a thickness greater than the second food product, and

controlling the rate of ascent of the lower heating plate includes adjusting at least one of a pressure applied to a food product resting upon the lower heating plate by ascent of the lower heating plate toward the upper heating plate or the rate of ascent to cook the first food product for a period of time longer than the second food product.

3. The method of claim 1 , wherein identifying the initial thickness of the food product includes identifying an initial thickness of a first food product and a second food product, the first food product having an initial thickness greater than the second food product, the method further comprising:

identifying the first and second food products being of a same type;

setting a final gap value for each of the first and second food products to be the same based on the identifying the first and second food products as being of the same type; and

controlling at least one of the pressure or the rate of ascent of the lower heating plate to cook the first food product for longer than the second food product.

4. The method of claim 1 , wherein controlling the rate of ascent of the lower heating plate further comprises adjusting the pressure applied to a food product resting upon the lower heating plate by ascent of the lower heating plate toward the upper heating plate based on the calculated difference between the initial gap value and the predefined final gap value.

5. The method of claim 1 , further comprising controlling the pressure applied to a food product resting upon the lower heating plate by ascent of the lower heating plate toward the upper heating plate until the predefined gap value is reached.

6. A cooking apparatus, comprising:

a base including a lower heating plate;

an upper heating unit including an upper heating plate; and

a controller configured to identify an initial thickness of a food product on the lower heating plate of the cooking apparatus, calculate whether a difference exists between an initial gap value corresponding to the initial thickness of the food product and a predefined final gap value, and when the step of calculating the difference between the initial gap value corresponding to the initial thickness of the food product and the predefined final gap value is complete, adjusting the position of the lower heating plate with respect to an upper heating plate to result in compression of the food product disposed upon the lower heating plate until there is no longer a difference between the thickness of the food product and the predefined final gap value, and controlling a rate of ascent of the lower heating plate toward the upper heating plate based on the calculated difference between the initial gap value and the predefined final gap value, controlling the rate of ascent of the lower heating plate until the predefined gap value is reached; and

sensing that the food product has been cooked based upon a combination of the predetermined final gap value being reached and the predetermined cook time being elapsed.

7. The cooking apparatus of claim 6 , further comprising at least one food product sensor configured to detect the initial thickness of the food product and transmit a corresponding food product sensor signal to the controller.

8. The cooking apparatus of claim 6 , further comprising an accelerometer to detect the rate of ascent of the lower heating plate.

9. The cooking apparatus of claim 6 , wherein identifying the initial thickness of the food product includes identifying the initial thickness of a first food product and a second food product, the first food product having a thickness greater than the second food product, and

controlling the rate of ascent of the lower heating plate includes controlling at least one of a motor or an actuator to adjust the rate of ascent to cook the first food product for a period of time longer than the second food product.

10. The cooking apparatus of claim 6 , wherein controlling the rate of ascent of the lower heating plate includes adjusting the rate of ascent of the lower heating plate toward the upper heating plate based on the calculated difference between the initial gap value and the predefined gap value.

11. The cooking apparatus of claim 6 , wherein further comprising controlling the pressure applied to a food product resting upon the lower heating plate by ascent of the lower heating plate toward the upper heating plate and controlling the rate of ascent of the lower heating plate includes controlling at least one of a motor and an actuator to adjust the pressure of at least one of the upper heating plate and the lower heating plate on the food product based on the calculated difference between the initial gap value and the predefined final gap value.

12. The cooking apparatus of claim 6 , wherein the controller is configured to control at least one of a motor and an actuator to control the rate of ascent of the lower heating plate until the predefined gap value is reached, and

the controller is configured to maintain the upper heating plate and the lower heating plate in position after the predefined gap value is reached until a predetermined cook cycle ending condition is detected.
