| titleOfInvention | Control system for and method of controlling a cooking appliance |
| abstract | ABSTRACT OF THE DISCLOSURE A cooking appliance, such as a deep fat fryer, includes programmable control system which monitors the operation of the cooking appliance and enables appropriate actions at proper times. The system includes a microcomputer which processes data and implements various timing and control functions. A microcomputer multiplex input circuit includes control switches to select operational states of the appliance, has a diode matrix for implementation of certain input data, interconnects the microcomputer with other circuits to implement multiplexing of the circuits for additional input data, and includes a monitor circuit to turn off the appliance if multiplexing stops. A temperature control circuit generates a signal responsive to the cooking fluid temperature and compares it with various reference signals representative of specified fluid temperatures, as called for by the computer. The comparison results are multiplexed to the microcomputer. A cooking control circuit includes an oscillator with an integrating capacitor. The cooking control circuit generates a voltage proportional the cooking fluid temperature, modifies it according to the desired doneness of the food being cooked and converts it to a current which charges the capacitor. The oscillator provides a series of pulses which vary in frequency as the temperature of the fluid varies. These pulses are multiplexed to the microcomputer. Output circuits connect the microcomputer to various contactors controlling operation of the appliance and to indicators, such as lights and a buzzer, which indicate the state of operations. The control system provides a low heat energy melt state and a cooking state with energy input suitable for cooking food. It signals when a load of food is done. Abstract of the Disclosure continued.... Additionally it enables signals when unwanted temperature conditions exist and turns off the heat when comparison results indicate the fluid temperature has gone outside set limits. |
