Abstract
A modular induction heated cooking hob inductor and hob are disclosed. The inductor is a wound conductor having turns at substantially right angles to previous turns. Parallel turns of the conductor are separated by a layer of insulation adjacent to the turns of the conductor. The hob may comprise multiple inductors. The inductor may have sensors for detecting a device to be heated and/or illuminatable segments that light up in response to the presence of an object to be heated.
Claims19
An inductor for a cooking hob comprising:
- a wound conductor with a rectangular cross section having a plurality of turns, each turn being a substantially a right angle to a previous turn and at substantially a right angle to a next turn;
- and
- a layer if insulation having a plurality of turns, each turn being at substantially a right angle to a previous turn and at substantially a right angle to a next turn, the layer of insulation being adjacent to the conductor and located between adjacent turns of the conductor, and being thinner than the thickness of the conductor.
A cooking hob comprising:
- an inductor, the inductor comprising
- a wound conductor with a rectangular cross section having a plurality of turns, each turn being at substantially a right angle to a previous turn and at substantially a right angle to a next turn;
- and
- a layer of insulation having a plurality of turns, each turn being at substantially a right angle to a previous turn and at substantially a right angle to a next turn, the layer of insulation being adjacent to the conductor, and located between adjacent turns of the conductor, and being thinner than the thickness of the conductor;
- a generator connected to the inductor for supplying power thereto.
A cooking hub supplied with a high frequency electric conductor comprising:
- a wound conductor with a rectangular cross section having a plurality of turns, each turn being at substantially a right angle to a previous turn and at substantially a right angle to a next turn;
- and
- a layer of insulation having a plurality of turns, each turn being at substantially a right angle to a previous turn and at substantially a right angle to a next turn, the layer of insulation being adjacent to the conductor, and located between adjacent turns of the conductor, and being thinner than the thickness of the conductor,
- wherein the generator supplies power to the indicator,
- a top surface formed by a protective electrically insulating layer underneath which the inductor is placed;
- a layer of ferrite underneath the inductor in order to loop the magnetic circuit of the inductor;
- a heat diffuser forming a magnetic screen underneath the layer of ferrite;
- a printed circuit board bearing the components of the generator associated with the inductor, this board being mounted underneath the diffuser, power components of the board being in heat-conduction contact therewith;
- the conductors being directly connected to the printed circuit;
- at least one of the supply conductors of the inductor passing through current sensors prior to the supply conductors being connected to the printed circuit.
