0013An “induction heating line element” is to be understood in particular to mean an object which carries electrical current in at least one heating operating state and which is in particular intended to provide at least a large part of the energy provided by the induction heating unit by means of the electrical current.

0014The induction heating line element consists in particular at least in large part of at least one electrically conductive material, in particular at least one metal and / or at least one metal alloy. For example, the induction heating line element could at least largely consist of copper and / or aluminum. “At least a large part” is to be understood in particular to mean a proportion, in particular a mass fraction and / or volume fraction, of at least 70%, in particular of at least 80%, advantageously of at least 90% and preferably of at least 95%.

0015A “buffer area” is to be understood in particular to mean a spatial area of ​​the induction heating line element which, in at least one heating operating state, at least partially compensates for at least one change in thermal extension, in particular at least a partial area, of the induction heating line element.

0016The phrase that the buffer area is intended to compensate at least partially for a thermal change in the extent of the induction heating line element is to be understood in particular to mean that the buffer area, in at least one heating operating state, changes the thermal extent of the induction heating line element alone or together with at least one further buffer area of ​​the Induction heating line element compensated. For example, the induction heating line element could, in particular exclusively, have the buffer area. The induction heating line element preferably has in particular at least two, advantageously at least four, particularly advantageously at least eight, preferably at least sixteen and particularly preferably a multiplicity of buffer areas which, in at least one heating operating state, in particular together compensate for the change in thermal extension of the induction heating line element.

0017The phrase that the buffer area is intended to at least partially compensate for "at least one" thermal extension change of the induction heating line element should be understood in particular to mean that the buffer area in at least one heating operating state compensates for a change in the thermal extension of at least one partial area of ​​the induction heating line element and / or a thermal change in the extension of at least two partial areas of the induction heating line element and / or a change in the thermal extension of the, in particular the entire, induction heating line element.

0018“Provided” is to be understood in particular to be specially designed and / or equipped. The fact that an object is provided for a specific function should in particular be understood to mean that the object fulfills and / or carries out this specific function in at least one application and / or operating and / or heating operating state. It is further proposed that the buffer area has at least one extension along at least one circumferential direction of the induction heating line element, and in particular additionally in at least one direction oriented at least substantially perpendicular to the extension plane, which is substantially smaller than an extension, in particular at least a partial section, of the induction heating line element along the circumferential direction of the induction heating line element and, in particular, as an entire extent of the induction heating unit in the circumferential direction of the induction heating line element. In particular, the direction is at least substantially identical to at least one circumferential direction of the induction heating line element. The phrase that the buffer area has at least one extension along at least one direction, which is "significantly smaller" than an extension of the induction heating line element along the direction, should in particular be understood to mean that an extension of the buffer area along the direction is a maximum of 20%, in particular a maximum 15%, advantageously at most 10%, particularly advantageously at most 8%, preferably at most 6% and particularly preferably at most 5% of the extent, in particular of the section, of the induction heating line element along the direction. The expression “substantially perpendicular” is intended here to define, in particular, an orientation of a direction relative to a reference direction, the direction and the reference direction, viewed in particular in one plane, enclosing an angle of 90 ° and the angle a maximum deviation of in particular a maximum of 8 ° , advantageously at most 5 ° and particularly advantageously at most 2 °. This enables in particular optimal heating properties and / or particularly low electrical losses and / or particularly low line losses and / or a particularly advantageous heat distribution.

0019It is also proposed that the induction heating line element has at least one compensation loop in the buffer area. In particular, the compensation loop has at least one compensation arc and / or at least one curved region of the induction heating line element. In particular, the compensation loop is provided for at least partial compensation of the change in thermal extension of the induction heating line element. The induction heating line element is at least partially flexible, in particular in the buffer area, in particular due to the compensating loop. In particular, the compensation loop and / or the buffer area absorbs at least one thermal change in the extension of the induction heating line element in at least one heating operating state and advantageously absorbs the, in particular recorded, thermal extension change of the induction heating line element. As a result, the change in thermal extension of the induction heating line element can be compensated for in a particularly simple and / or uncomplicated manner, which in particular enables rapid and / or uncomplicated production of the induction heating line element.

0020For example, the induction heating line element in the buffer area could have at least two, in particular at least three, advantageously at least four, particularly advantageously at least five, preferably at least six and particularly preferably a plurality of compensating loops. The compensating loops could, for example, be arranged in the form of a helix. In particular, the induction heating line element could have at least one screw-like shape in the buffer area, which could be defined in particular by the compensating loops. The induction heating line element could have at least a V-like shape in the buffer area, which could be defined in particular by the compensating loops. The induction heating line element preferably has at least one partial section in the buffer area, which is aligned, in particular at least essentially, in at least one plane, which is in particular at least substantially perpendicular to at least one extension plane, which is in particular spanned by at least a large part of the induction heating line element U-like shape and / or, in particular at least, has an at least substantially arcuate shape. The subsection of the induction heating line element is defined in particular by the compensating loop and / or is identical to the compensating loop. As a result, in particular with a geometrically simple configuration, compensation for the change in thermal extension of the induction heating line element can be achieved, as a result of which, in particular, low manufacturing costs can be achieved.

0021For example, the induction heating line element could have at least one partial section in the buffer area, which could in particular be defined by the compensation loop and / or be designed identically to the compensation loop and which in particular could be arranged at least to a large extent within at least one extension plane spanned by at least a large part of the induction heating line element. The induction heating line element preferably has at least one partial section in the buffer area, which is defined in particular by the compensation loop and / or is identical to the compensation loop and which protrudes from at least one extension plane spanned by at least a large part of the induction heating line element. The sub-area of ​​the induction heating line element has in particular at least one point which is at a distance from the extension plane of at least 2 mm, in particular of at least 3 mm, advantageously of at least 4 mm, particularly advantageously of at least 5 mm and preferably of at least 6 mm. In particular, the partial area of ​​the induction heating line element has at least one point which is at a distance from the extension plane of a maximum of 40 mm, in particular a maximum of 30 mm, advantageously a maximum of 20 mm, particularly advantageously a maximum of 15 mm and preferably a maximum of 10 mm. As a result, in particular a particularly advantageous construction of the induction heating line element can be achieved, since the induction heating line element can be produced in a particularly simple manner, for example by using simple stamping technology and / or pressing technology and / or forming technology.

0022The induction heating line element could, for example, in particular exclusively, have the buffer area. The induction heating line element preferably has at least one further buffer area, which is provided to at least partially compensate for at least one thermal change in the extension of the induction heating line element, which is caused in particular by at least one thermal expansion, and which is closest to the buffer area in the circumferential direction of the induction heating line element. In particular, an extent of the induction heating line element from the buffer area to the further buffer area in the circumferential direction is at most as large as an extent of the induction heating line element from the buffer area to at least one second additional buffer area of ​​the induction heating line element that differs from the further buffer area. In this way, a particularly advantageous and / or optimal construction can be achieved in particular, since the change in thermal extension, in particular in several subregions, of the induction heating line element can be compensated for in a particularly distributed manner.

0023It is further proposed that the buffer area and the further buffer area are part of a thermal compensation unit, which is intended to at least change at least one outer dimension of the induction heating line element and advantageously of the induction heating unit, in particular in at least one extension plane spanned by at least a large part of the induction heating line element to prevent essentially and advantageously completely. In at least one heating operating state, the thermal compensation unit reduces in particular a change in the outer dimension of the induction heating line element, in particular in the extension plane, to a maximum of 10%, in particular to a maximum of 7%, advantageously to a maximum of 5%, particularly advantageously to a maximum of 3%, preferably to a maximum of 2 % and particularly preferably to a maximum of 1%, in particular an outer dimension of the induction heating line element outside the heating operating state. In particular, the thermal compensation unit is provided to at least substantially and advantageously completely prevent at least a change in a surface extension spanned by the induction heating line element, and advantageously by the induction heating unit, in the extension plane. In particular, the thermal compensation unit in at least one heating operating state reduces a change in an area extension spanned by the induction heating line element in the extension plane to a maximum of 10%, in particular to a maximum of 7%, advantageously to a maximum of 5%, particularly advantageously to a maximum of 3%, preferably to a maximum of 2% and particularly preferably to a maximum of 1%, in particular of an area extension spanned by the induction heating line element outside the heating operating state in the extension plane. A surface extension spanned by the induction heating line element in at least one heating operating state in the extension plane differs from a surface extension spanned by the induction heating line element outside the heating operating state in the extension plane by a maximum of 10%, in particular by a maximum of 7%, advantageously by a maximum of 5%, particularly advantageously by a maximum of 3 %, preferably by a maximum of 2% and particularly preferably by a maximum of 1%. The thermal compensation unit has at least three, in particular at least four, advantageously at least six, particularly advantageously at least eight, preferably at least sixteen and particularly preferably a multiplicity of buffer areas, specifically in particular including the buffer area and the further buffer area and / or in addition to the buffer area and the further buffer area. As a result, in particular optimal heating properties and / or a long-lasting design can be achieved, as a result of which in particular a high level of operating comfort and / or brand loyalty of an operator can be ensured.

0024For example, the induction heating line element, in particular in the extension plane, could have at least one outer dimension, which could in particular be oval and / or circular and / or elliptical. The induction heating line element has, in particular in the extension plane, in particular at least one outer dimension, which is in particular rectangular and / or square. For example, the induction heating line element could in particular be tubular and / or at least one oval-like and / or circular and / or elliptical and / or in at least one cross-sectional plane, which in particular could be oriented at least substantially perpendicular to the extension plane and / or to at least one longitudinal direction of the induction heating line element / or have a ring-like shape. The induction heating line element is preferably flat and / or strip-like and in particular has at least one longitudinal extent which is substantially greater than a transverse extent of the induction heating line element and than a thickness of the induction heating line element and which in particular has at least one transverse extent which is in particular substantially greater than a thickness of the Induction heating line element.

0025It is further proposed that the induction cooking device device has at least one fastening element for at least partially fastening the induction heating line element, which is arranged in the circumferential direction of the induction heating line element, in particular at least essentially centrally, between the buffer area and the further buffer area. Starting from the buffer area and as it progresses in the circumferential direction of the induction heating line element, the fastening element follows in particular, and in particular the further buffer area follows the fastening element. In particular, a distance in the circumferential direction of the induction heating line element from the buffer area to the fastening element and a further distance in the circumferential direction of the induction heating line element from the fastening element to the further buffer area are at least substantially identical. The route and the further route differ in particular by a maximum of 10%, in particular by a maximum of 7%, advantageously by a maximum of 5%, particularly advantageously by a maximum of 3%, preferably by a maximum of 2% and particularly preferably by a maximum of 1%. In particular, the fastening element, in particular in at least one heating operating state, fastens at least one fastening section of the induction heating line element, in particular to at least one fastening object. In particular in at least one heating operating state, the fastening element in particular fastens the fastening section of the induction heating line element in particular statically and / or immovably. The fastening element fixes, in particular in at least one heating operating state, in particular the fastening section of the induction heating line element, in particular on at least one fastening object. In particular, the induction cooking device device has the fastening object. For example, the fastening object could be at least one muffle wall, in particular the muffle, and / or at least one muffle insulation unit, which could in particular be part of the induction cooking device device. The induction heating line element has in particular at least one fastening object which is provided for fastening the induction heating line element to the fastening object and by means of which the induction heating line element, in particular in at least one heating operating state, is fastened and / or fixed to the fastening object. The phrase that the fastening element is intended for "at least partial" fastening of the induction heating line element is to be understood in particular to mean that the fastening element, in particular in at least one heating operating state, fastens and / or fixes the induction heating line element alone or advantageously together with at least one further fastening element . In particular, the fastening element is fastened and / or fixed, in particular in at least one heating operating state, at least one fastening section of the induction heating line element. In particular, the further fastening element is fastened and / or fixed, in particular in at least one heating operating state, at least one further fastening section of the induction heating line element that is different from the fastening section of the induction heating line element. For example, the fastening element could fix the induction heating line element, in particular on the fastening object, by means of at least one fastening caused by clamping and / or by means of at least one fastening caused by latching and / or by means of at least one using at least one clamp, in particular using at least one wire clamp. caused fastening and / or by means of at least one fastening caused by at least one flap and / or by at least one brim and / or by means of at least one fastening caused by at least one clamp and / or by means of at least one fastening caused by at least one seam and / or by means of at least attach and / or fix an attachment caused by pressing. As a result, a stable configuration can be achieved in particular. In particular, a change in the thermal extension of the induction heating line element can be compensated for at least substantially equally distributed by the buffer area and the further buffer area, whereby in particular a change in an external dimension of the induction heating line element and / or a change in thermal extension of the induction heating line element can be minimized.

0026In particular, the fastening element and the buffer area are spaced apart from one another in the plane of extension, in particular at maximum, in the circumferential direction of the induction heating line element. Starting from a center point and / or center of gravity of the induction heating line element in the extension plane, the fastening element and the buffer area in the extension plane in the circumferential direction of the induction heating line element are at least 10 °, in particular by at least 15 °, advantageously by at least 20 °, particularly advantageously by at least 25 °, preferably spaced by at least 30 ° and particularly preferably by at least 40 °.
