Claims
- 1. An electrical energy cooking device for cooking food, comprising, in combination, first and second plate electrodes positionable in spaced relation to one another for forming a cooking compartment of pre-determined minimum thickness, means for heating said plates to thereby pre-heat the said plates to transfer heat from said plates to said food placed therebetween, and first and second electronic control means connected to said electrodes to selectively couple electrical energy by means of said electrodes through said food, said first electronic control means controlling the total electrical energy applied to said food in response to a selected level, and said second electronic control means controlling and maintaining the rate at which said electrical energy is applied to said food relatively constant at a selected level during a selected cooking period.
- 2. An apparatus as in claim 1 wherein said control means provides a pre-set time delay after said heat transfer is initiated before the electrical energy is applied to said food.
- 3. An apparatus as in claim 1 wherein said control means include current control means, first circuit means for providing a voltage representative of the voltage being developed across said electrodes, second circuit means for providing a current representative of current being coupled to said electrodes, multiplier means for receiving said representative voltage and current to provide a voltage proportional to instantaneous power input to said food.
- 4. Apparatus as in claim 3 further including filter means for receiving said proportional voltage and providing a voltage indicative of the average power input to the food during a given period of time, and means to connect said voltage indicative of the average power input to control the conduction of said current control means and thereby the rate of power input to the food.
- 5. An apparatus as in claim 4 wherein said cooking devide operates from a source of alternating current energy, means to provide pulses in synchronism with the alternating current for controlling the conduction of the current control means, integrating means for providing a signal representative of the integration of the power input to said food, comparator means for comparing the total electrical energy input to the food with a pre-selected input level to turn OFF said synchronized pulses when said total electrical energy input equals the pre-selected input level to thereby turn OFF the power input to said food.
- 6. An apparatus as in claim 1 wherein said first electronic means includes means for integrating the electrical energy applied to the food during the selected cooking period and means for switching off the power when the selected level of total electrical energy is attained.
