Abstract
An induction heating system (40) is provided and includes a plurality of induction heating coils (118). Touch control pads (50, 52, 70, 72) are provided together with circuitry (80) for generating energization control signals. Circuitry (112, 116) is provided for electrically energizing the induction heating coils (118). An electronic digital processor (82) is responsive to the energization control signals for generating energization signals for actuating and controlling the energization circuitry (112, 116) to thereby vary the energization of the plurality of induction heating coils (118).
Claims2
In an induction cooking system, the combination comprising:
- a plurality of induction heating coils operable at a plurality of power levels;
- energization means for electrically energizing said plurality of induction heating coils;
- a first touch control pad associated with each one of said plurality on induction heating coils for being touched to increase the output of said energization means to thereby increase the power level of said associated one of said plurality of induction heating coils;
- a second touch control pad associated with each one of said plurality of induction heating coils for being touched to decrease the output of said energization means to thereby decrease the power level of said associated one of said plurality of induction heating coils;
- a digital microprocessor responsive to said energization control signals generated by said first and second touch control pads for actuating and controlling said energization means to thereby vary the energization of said plurality of induction heating coils;
- and
- a single display means associated with said plurality of induction heating coils interconnected to said digital microprocessor for alternately and selectively displaying at a single predetermined location on said single display means a representation of the instantaneous power level of a selected one of said plurality of induction heating coils.
