An “operational state” is intended to be understood in this case and hereinafter as a functionally coupled state in which a shortest connection between the supplying induction element and the receiving induction element is minimal and in which the supplying induction element, in particular, inductively transmits energy to the receiving induction element and in which, in particular, the supplying induction element and the receiving induction element are functionally coupled together. Advantageously in the operational state the supplying induction element and the receiving induction element, when viewed perpendicular to the plane, are arranged at least partially and advantageously at least for the most part so as to overlap. “At least for the most part” is intended to be understood, in particular, as in a proportion, in particular a mass portion and/or volume portion, of at least 70%, in particular of at least 80%, advantageously of at least 90% and preferably of at least 95%.

For example, the further sub-region could be at least partially, in particular at least for the most part, and advantageously entirely identical to at least one first portion and/or to at least one second portion of the supplying induction element.
The phrase that an object in the operational state is arranged “at an angle” relative to a plane is intended to be understood, in particular, that in the operational state the object encloses with the plane a minimum angle of more than 0° and a maximum of 90°. In particular, in the operational state the object encloses with the plane a minimum angle of at least 5°, in particular of at least 10°, advantageously of at least 15°, particularly advantageously of at least 20°, preferably of at least 25° and particularly preferably of at least 30°.

The expression “substantially perpendicular” in this case is intended to define, in particular, an orientation of a direction relative to a reference direction, wherein the direction and the reference direction, in particular viewed in one plane, enclose an angle of 90°, and the angle has a maximum deviation of in particular less than 8°, advantageously of less than 5° and particularly advantageously of less than 2°.
The supply unit has, in particular, at least one positioning plate which is provided, in particular, for positioning a positioning unit which is configured as a positioning unit. A “positioning plate” is intended to be understood, in particular, as at least one, in particular, plate-like unit which is provided for positioning at least one receiving unit configured as a positioning unit, in particular for the purpose of energy transmission to the receiving unit. For example, the positioning plate could be configured as a substrate, in particular a base and/or a floor. The positioning plate could alternatively or additionally be configured, for example, as a sub-region of at least one worktop, in particular at least one kitchen worktop, in particular of the supply unit. Alternatively or additionally, the positioning plate could be configured as a hob plate. The positioning plate which is configured as a hob plate could form, in particular, at least one part of a hob external housing and, in particular, together with at least one external housing unit, to which the positioning plate which is configured as a hob plate could be connected in particular in at least one assembled state, could form the hob external housing at least for the most part.

In the operational state, the positioning plate in particular forms the plane. The plane, in particular, is identical to a principal extension plane of the positioning plate. A “principal extension plane” of an object is intended to be understood, in particular, as a plane which is parallel to a largest side surface of a smallest imaginary geometric cuboid which only just fully encloses the object and runs through the central point of the cuboid.
In particular, the sub-region has at least one principal extension plane which is oriented at an angle relative to the principal extension plane of the positioning plate and/or to the plane.
“Provided” is intended to be understood, in particular, as specifically programmed, designed and/or equipped. By an object being provided for a specific function is intended to be understood, in particular, that the object fulfills and/or performs this specific function in at least one use state and/or operational state.
It is further proposed that the supplying induction element has at least one first portion with at least one first principal extension plane and at least one second portion with at least one second principal extension plane which differs from the first principal extension plane. For example, the supplying induction element could have at least one third portion with at least one third principal extension plane which, in particular, could differ from the first principal extension plane and from the second principal extension plane. As a result, in particular, a compact and/or space-saving configuration may be achieved. In particular, a particularly high degree of efficiency and/or uniform electromagnetic radiation may be achieved.
The first principal extension plane and the second principal extension plane could be oriented, for example, at an angle relative to one another. Preferably, the first principal extension plane and the second principal extension plane are oriented at least substantially parallel to one another. “Substantially parallel” is intended to be understood here, in particular, as an orientation of a direction relative to a reference direction, in particular in one plane, wherein the direction relative to the reference direction has a deviation, in particular, of less than 8°, advantageously of less than 5° and particularly advantageously of less than 2°. Advantageously, the first principal extension plane and/or the second principal extension plane are oriented at least substantially parallel to a principal extension plane of the positioning plate and/or to the plane. The first portion and the second portion are arranged spaced apart from one another, in particular, in at least one assembled state in a direction which is oriented parallel to the shortest connection between the supplying induction element and the receiving induction element. As a result, in particular, a particularly high degree of efficiency may be achieved.
It is further proposed that the sub-region is arranged at least for the most part between the first portion and the second portion. The sub-region connects, in particular, the first portion and the second portion together. In particular, the principal extension plane of the sub-region is oriented at an angle relative to the first principal extension plane and/or to the second principal extension plane. Particularly advantageously, an angle between the principal extension plane of the sub-region and the first principal extension plane and/or the second principal extension plane is at least substantially 45°. For example, the supplying induction element in the sub-region could have an at least substantially double-bend-shaped and/or S-shaped cross section. “At least substantially” is intended to be understood, in particular, in this context as a deviation of a maximum of 20°, preferably a maximum of 5° and particularly preferably a maximum of 0.5°. As a result, in particular, a simple and/or uncomplicated and/or rapidly executable production and/or assembly may be possible.
Moreover, it is proposed that the supply unit has at least one further supplying induction element which has at least one further first portion which extends at least substantially inside the first principal extension plane and at least one further second portion which extends at least substantially inside the second principal extension plane. As a result, in particular, an optimal energy transmission may be possible. In particular, it may be achieved that in a first operational state in which the receiving induction element is arranged above the supplying induction element and in a second operational state in which the receiving induction element is arranged above the further supplying induction element, a spacing between the receiving induction element and the corresponding supplying induction element is equal. In particular, at least one of, advantageously at least a large part of, and preferably each of the supplying induction elements has an identical spacing from the receiving induction element, in an operational state in which the receiving induction element is arranged above the corresponding supplying induction element. In particular, due to an identical configuration of the supplying induction elements advantageously a simple and/or uncomplicated control may be possible, whereby in particular low costs may be achieved. In particular, a particularly compact construction and/or a high degree of efficiency may be achieved.
It is additionally proposed that the supplying induction element and the further supplying induction element are arranged so as to overlap one another at least in some sections, when viewed perpendicular to the plane and/or to the first principal extension plane and/or to the second principal extension plane. In particular, the supplying induction element and the further supplying induction element are arranged so as to overlap at least partially in a direction which is oriented parallel to the shortest connection between the supplying induction element and the receiving induction element. The phrase that the supplying induction element and the further supplying induction element are arranged so as to overlap “at least partially” is intended to be understood, in particular, that at least a partial portion of the supplying induction element and at least a partial portion of the further supplying induction element are arranged so as to overlap. For example, merely a partial portion of the supplying induction element and at least a partial portion of the further supplying induction element could be arranged so as to overlap, when viewed perpendicular to the first principal extension plane and/or to the second principal extension plane, wherein in particular a further partial portion of the supplying induction element and a further partial portion of the further supplying induction element may be arranged without overlapping. Alternatively, for example, the supplying induction element and the further supplying induction element could be arranged so as to overlap fully and/or to be congruent, when viewed perpendicular to the first principal extension plane and/or the second principal extension plane. Particularly advantageously, the further first portion of the further supplying induction element and the second portion of the supplying induction element could be arranged so as to overlap at least partially and advantageously at least for the most part. As a result, in particular, a particularly compact and/or space-saving construction and/or a high degree of efficiency may be achieved. For example, an arrangement of the supplying induction element and the further supplying induction element in a row and/or in a matrix may be possible.
It is further proposed that the supplying induction element has an oval, in particular circular and/or elliptical, shape when viewed perpendicular to the plane and/or to the first principal extension plane and/or to the second principal extension plane. As a result, in particular, simple and/or uncomplicated production and/or assembly may be achieved.
For example, the supplying induction element and/or the further supplying induction element could have a polygonal shape, such as for example an at least substantially rectangular and/or square and/or n-angular shape when viewed perpendicular to the plane and/or to the first principal extension plane and/or to the second principal extension plane. Preferably, the supplying induction element and/or the further supplying induction element has a rectangular and/or square shape, when viewed perpendicular to the plane and/or to first principal extension plane and/or to the second principal extension plane. As a result, in particular, a compact arrangement of the supplying induction elements may be possible.
The supply unit could be configured, for example, as an energy charging device, in particular as an induction energy charging device and, in particular, provided to transmit energy by means of the supplying induction element to at least one receiving unit which could be configured in particular as a mobile device, such as for example a laptop and/or a tablet and/or a mobile telephone, and/or a hand-held power tool and/or a self-propelled implement and/or as a remote control and/or a remote operation. Alternatively or additionally, the supply unit could be configured, for example, as a cooking appliance, in particular as an induction cooking appliance, such as for example in particular an oven, in particular an induction oven and/or as a grill, in particular as an induction grill. Preferably, the supply unit is configured as a hob and advantageously as an induction hob. In particular, by means of the energy provided by the supplying induction element the supply unit heats at least one part of the receiving unit, in particular at least a receiving space of the receiving unit. As a result, in particular, the receiving unit may be supplied with the energy provided for the receiving unit, whereby in particular optimal cooking results and/or a reliable functionality of electrical and/or electronic units integrated in the receiving unit may be achieved.
Moreover, it is proposed that the receiving unit is configured as a positioning unit which is provided, in particular, for positioning on a positioning plate and which has at least one receiving space for receiving food, in particular food to be cooked. A “positioning unit” is intended to be understood, in particular, as a unit which is provided for coupling to the supply unit, in particular to the supplying induction element and which, in particular during the course of coupling to the supply unit receives and/or absorbs energy from the supply unit in at least one operational state. The positioning unit could have, for example, at least one item of cookware. Alternatively or additionally, the positioning unit could have at least one pad apparatus which, in particular, could be provided for positioning at least one item of cookware, in particular the item of cookware. The pad unit could be provided, in particular, for an arrangement between the positioning plate and the item of cookware. Alternatively or additionally, the positioning unit could have at least one housing unit which could be configured, in particular, as an external housing unit and, in particular, could define an external housing. In particular, at least one object of the positioning unit, in particular at least one receiving induction element and/or the transmitting unit, could be integrated at least for the most part in the housing unit. The positioning unit has, in particular, at least one coupling unit which is provided, in particular, for coupling to the supply unit. The coupling unit has, in particular, at least one coupling element which is provided, in particular, for coupling to the supply unit. The coupling element could be configured, in particular, as a coil and/or as an induction element, in particular as a receiving induction element. In particular, the positioning unit could have at least two, advantageously at least three, preferably at least five and particularly preferably a plurality of coupling elements which in each case could be provided, in particular, for coupling to the supply unit and configured, in particular, as receiving induction elements. In particular, in the operational state the receiving induction element could heat a wall at least partially defining the receiving space by means of at least one portion of the energy received by the supplying induction element. A “receiving space” is intended to be understood, in particular, as a spatial region which, in the operational state in which the supply unit in particular transmits energy to the receiving unit, is defined at least for the most part by the receiving unit and in which, in particular, food may be arranged in the operational state. The food could be arranged, in particular, in the receiving space, in particular in fluid form, in particular in liquid form and/or at least for the most part in liquid form and/or in solid form in the receiving space. As a result, in particular, food may be cooked particularly efficiently and/or in a targeted manner since, in particular, an energy required for a cooking process may be accurately transmitted.
A particularly optimized and/or efficient energy transmission may be achieved, in particular, by a method for operating an induction energy transmission system which comprises at least one supply unit that has at least one supplying induction element provided to supply energy, and at least one receiving unit which comprises at least one receiving induction element, wherein energy is received from the supplying induction element when in at least one operational state in which a shortest connection between the supplying induction element and the receiving induction element is minimal, and wherein the supplying induction element comprises at least one sub-region which in the operational state is oriented at an angle relative to a plane that is at least substantially perpendicular to the shortest connection between the supplying induction element and the receiving induction element.

In an operational state, the induction heating units 10a, which in particular are activated, supply energy at least to a positioned receiving unit 106a, in particular by means of the magnetic flux. In an operational state, the control unit 46a controls an energy supply to the, in particular, activated induction heating units 10a, 32a, 48a. In an installed position, the induction heating units 10a are arranged below the positioning plate 42a.
One of the induction heating units 10a, 32a, 48a is shown by way of example in
The induction heating element 12a has a first portion 20a. The induction heating element 12a has a second portion 22a. The first portion 20a extends inside a first principal extension plane 24a. The second portion 22a extends inside a second principal extension plane 26a. The second principal extension plane 26a is different from the first principal extension plane 24a. The first principal extension plane 24a and the second principal extension plane 26a run parallel to one another. The first principal extension plane 24a and the second principal extension plane 26a are offset parallel to one another. The first principal extension plane 24a extends parallel to the hob plane 14a. The sub-region 16a is arranged between the first portion 20a and the second portion 22a. The principal extension plane 18a of the sub-region 16a runs obliquely to the first principal extension plane 24a. The principal extension plane 18a of the sub-region 16a runs obliquely to the second principal extension plane 26a. The first portion 20a and the second portion 22a are of equal size. The first portion 20a and the second portion 22a have an equal surface area, width and/or length. The induction heating unit 10a and a further induction heating unit 32a of the induction hob apparatus are shown in
The further induction heating unit 32a comprises a further induction heating element 34a. The further induction heating element 34a has a further first portion 50a and a further second portion 52a. The further first portion 50a extends in an operational state and/or in an assembled state inside the first principal extension plane 24a. The further second portion 52a extends inside the second principal extension plane 26a. The induction heating element 12a and the further induction heating element 34a partially overlap one another in a direction 36a viewed perpendicular to the first principal extension plane 24a. In particular, the further first portion 50a of the further induction heating element 34a overlaps at least for the most part the second portion 22a of the induction heating element 12a.
In a variant of the invention, the induction heating element 12a′ of the induction heating unit 10a′ has a third portion 54a′ in addition to the first portion 20a′ and second portion 22a′. The third portion 54a′ extends at least substantially inside a third principal extension plane. The third principal extension plane is different from the first and second principal extension planes 24a′, 26a′. The first principal extension plane 24a′, the second principal extension plane 26a′ and the third principal extension plane run parallel to one another. The first principal extension plane 24a′, the second principal extension plane 26a′ and the third principal extension plane are arranged offset in parallel to one another. The second principal extension plane 26a′, viewed in a direction 36a′ perpendicular to the first principal extension plane 24a′, is arranged between the first principal extension plane 24a′ and the third principal extension plane. The induction heating element 12a′ has two sub-regions 16a′ which run along a principal extension plane 18a′ of one of the sub-regions 16a′ and a principal extension plane of a further sub-region 16a′ which both deviate from the hob plane 14a′. The principal extension plane 18a′ of the sub-region 16a′ and the principal extension plane of the further sub-region 16a′ run parallel to one another. The portions 20a′, 22a′, 54a′ divide the induction heating element 12a′ in at least one direction into three parts of equal length. As is shown, a plurality of induction heating elements 12a′ overlap one another such that the first portion 20a′ and the second portion 22a′ of an induction heating element 12a′ overlaps a further second portion 52a′ and a further third portion 62a′ of a further induction heating element 34a′ of an induction heating unit 32a′.

In a method for producing the induction hob apparatus, in a method step the first portion 20a of the induction heating element 12a of the induction heating unit 10a is supplied with at least one first force component 80a perpendicular to a principal extension plane of the induction heating unit 10a. The force component 80a in this case acts on one of the heating element supports 28a, 30a. In this case the force component 80a is exerted on the second heating element support 30a. A force component 82a opposing the force component 80a acts in the second portion 22a on the induction heating element 12a of the induction heating unit 10a via the first heating element support 28a. At least by means of the first force component 80a the principal extension plane 24a of the first portion 20a is displaced relative to a principal extension plane 26a of the second portion 22a of the induction heating unit 10a. In this case the heating element supports 28a, 30a rupture along their predetermined rupture points. The induction heating element 12a is bent and/or permanently plastically deformed in some sections. More specifically, the induction heating unit 10a is folded and/or bent twice. The induction heating element 12a in this case is bent in a double-bend-shaped and/or S-shaped manner. The heating element supports 28a, 30a form an insulating layer. This insulating layer is separated in an intermediate portion arranged between the first portion 20a and the second portion 22a, in particular separated in a controlled manner. Subsequently, the induction heating units 10a thus produced are arranged so as to overlap one another as shown by way of example in
