1. An induction based cooking system for cooking hobs having a plate on which cooking utensils can be placed comprising:
- a heating unit adapted for positioning below the plate, the unit including, as an integrally mountable element, a flat housing containing;
at least one flat induction coil means;
high frequency generation means including electronic power switch means for energizing the induction coil means;
electronic control means for controlling the high frequency generating means;
a heat sink provided with cooling ribs on at least one side; and
a fan for blowing cooling air alongside the cooling ribs;
wherein the heat sink is a support for the induction coil means, said induction coil means being located on the heat sink and in heat conductive connection therewith; and
the electronic power switch means being mounted in heat conductive connection with the heat sink.

Abstract
An induction based point heating system for cooking utensils or the like contains induction coils positioned below a plate, e.g. a glass ceramic plate. It is constructed as a cohesive component and includes induction generating means and the associated power, frequency generation or control electronics for the induction coils. The component is in the form of a flat plate or tray, which can be pressed from below against the plate. The induction coil is constructed as a flat, disk-like coil, which on its side remote from the plate is adjacent to a magnetic yoke such as a preferably segmented ferrite layer.
