Abstract
In one aspect, the present invention provides a consumer appliance that uses RF energy to heat foods stored in a container that is suitable for RF heating.
Claims12
A system that uses induction heating to heat food stored in a container, the system comprising:
- a housing having a door, wherein a cylindrical cavity configured to receive a cylindrical container is formed in the door of the housing and the door is configured to move between an open position in which the cavity is accessible to a user of the system and a closed position in which the cavity is not accessible to the user;
- a cylindrical induction heating coil housed in the door of the housing and configured to provide energy to a container placed in the cavity, wherein the cylindrical induction heating coil is coaxial with the cylindrical cavity and the cylindrical induction heating coil is wrapped around the cylindrical cavity;
- an oscillator for providing an RF signal;
- a power generator housed in the housing and coupled to the induction heating coil and to the oscillator, wherein the power generate is configured to amplify the RF signal provided by the oscillator;
- and
- a controller configured to control the operation of the power generator.
