Abstract
A delay timer incorporated into an induction cooking cartridge permits the use of the induction cooking cartridge with conventional modular cooktops including bi-metal power switches without damage to the induction circuitry.
Claims16
An induction cooking cartridge for a cooktop with a modular chassis having a bi-metal switch with a transient settling time, comprising:
- an inverter power control circuit electrically connectable to the bi-metal switch;
- an inverter circuit electrically connected to the inverter power control circuit;
- and
- a delay timer disposed between the inverter power control circuit and the inverter circuit for delaying operation of the inverter circuit during the settling time.
In a modular cooktop having a chassis configured to receive at least one modular cooking cartridge and a bi-metal switch mounted on the chassis for providing power to the modular cooking cartridge, the improvement comprising:
- a modular induction cooking cartridge including an induction cooking unit;
- and
- a delay timer for delaying operation of the induction cooking unit for an amount of time at least about as long as a settling time associated with the bi-metal switch.
In a modular cooktop including a chassis for receiving at least one modular induction cooking cartridge and a bi-metal switch attached to the chassis for providing power to the modular induction cooking cartridge, the improvement comprising:
- an inverter power control circuit;
- an inverter circuit;
- and
- a delay timer electrically connected to the inverter power control circuit and the inverter circuit for delaying operation of the inverter circuit at least as long as the settling time of the bi-metal switch.
A method of using an induction cooktop with a modular cooktop chassis having a bi-metal switch with a settling time, comprising the steps of:
- providing an induction cooking cartridge having an inverter cooking circuit in said cooktop;
- and
- introducing a time delay in the operation of the inverter cooking circuit upon operation of the bi-metal switch.
