    Cooking device.
    The present invention refers to a cooking appliance device according to the preamble of claim 1.
    Through the state of the art, a cooking device device made as a cooking hob device with a heating unit is already known. The heating unit has an internal heating element and an essentially polygonal external heating element. The external heating element has a main extension plane and a direction of the main extension. When the heating unit is perpendicularly observed on the main extension plane, the external heating element has an essentially rectangular conformation, and the internal heating element has an essentially circular conformation. When the heating unit is perpendicularly observed on the main extension plane, the density of the turns between the innermost turn of the inner heating element and the outermost turn of the outer heating element is considerably lower in the direction of the main extension that the density of the turns between the innermost turn of the inner heating element and the outermost turn of the outer heating element in an orthogonal direction oriented perpendicular to the direction of the main extension. As a consequence of the lack of symmetry with respect to the direction of the main extension and the orthogonal direction, an irregular heat distribution is obtained in the supported cooking battery. In addition, this lack of symmetry with respect to the direction of the main extension and the orthogonal direction results in power losses, which cause hot spots in the orthogonal direction compared to the direction of the main extension.
    The invention solves the technical problem of providing a generic cooking appliance device with better properties in relation to the heating of the cooking battery resting on it. According to the invention, this technical problem is solved by the features of claim 1, while advantageous embodiments and improvements of the invention can be extracted from the secondary claims.
    The invention refers to a cooking appliance device, in particular, to a cooking hob device, with at least one heating unit having at least one internal heating element and at least one external heating element approximately or exactly polygonal, where at least one of the heating elements has a main extension plane and a direction of the main extension, where, when the heating unit is perpendicularly observed on the main extension plane, the density of the turns between the turn more inside of the inner heating element and the outermost turn of the outer heating element in the direction of the main extension approximately or exactly coincides with the density of the turns between the innermost turn of the inner heating element and the outermost turn of the element of external heating in at least one orthogonal direction l oriented approximately or exactly and, preferably, totally perpendicular to the direction of the main extension.
    Through the embodiment according to the invention, optimum heating of the supported cooking battery can be achieved. In particular, optimized surface heating can be achieved in comparison to a heating unit with two oval heating elements, since it is possible to achieve a uniform distribution of power losses and these can be adapted in the direction of extension Main and in the orthogonal direction. Uniform surface heating can be achieved independently of a ferrite arrangement. Thanks to the external heating element

An optimized thermal distribution in the supported cooking battery is made possible. It is possible to achieve a simple heating unit manufacturing process. In areas that differ from areas arranged in the direction of the main extension and in the orthogonal direction, sufficient space can be obtained to provide at least one other unit, such as at least one sensor unit. The density of the turns approximately or exactly the same in the direction of the main extension and in the orthogonal direction can be achieved for different embodiments of the approximate or exactly polygonal conformation of the external heating element.

    of the main extension. When the heating unit is perpendicularly observed on the main extension plane, the heating elements are elongated. The term "approximately or exactly in parallel" includes the concept of the orientation of a direction relative to a reference direction in a plane, where the direction present with respect to the reference direction is a deviation less than 8 °, advantageously, less than 5 ° and, particularly advantageously, less than 2 °. Thus, a simple and / or rapid heating unit manufacturing process is made possible, so that the costs can be lowered.
    When the heating unit is perpendicularly observed on the main extension plane, the external heating element could have, by way of example, an approximate or exactly triangular and / or approximate or exactly n-angular conformation, where n could be greater than three and preferably greater than six. Advantageously, when the heating unit is perpendicularly observed on the main extension plane, the external heating element has an approximate or exactly rectangular shape. When the heating unit is perpendicularly observed on the main extension plane, the external heating element could, by way of example, have an approximate or exactly square shape. When the heating unit is perpendicularly observed on the main extension plane, the external heating element has an approximate or exactly rectangular conformation and distinct from a square conformation. In this way, two heating units of analogous structure can be arranged compactly with respect to each other, so that an optimized surface heating can be achieved.
    Likewise, it is proposed that, when the heating unit is perpendicularly observed on the main extension plane, the internal heating element has an approximate or exactly oval shape. When the heating unit is perpendicularly observed on the main extension plane, the interior heating element could have an approximate or exactly circular shape. Alternatively or additionally, when the heating unit is perpendicularly observed on the main extension plane, the interior heating element could have an approximate or exactly ellipsoidal conformation. In this way, space between the heating units can be created to provide at least one other unit which, when the heating unit is perpendicularly observed on the main extension plane, could be arranged in corner areas of the external heating element between the element of internal heating and the external heating element. Thanks to the approximate or exactly oval conformation of the interior heating element, in comparison with an interior heating element with an approximate or exactly rectangular conformation it is possible to avoid changes in the direction when winding a heating line, thus making possible a simple manufacturing process.
    Furthermore, it is proposed that, when the heating unit is perpendicularly observed on the main extension plane, the interior heating element has an approximate or exactly rectangular shape. When the heating unit is perpendicularly observed on the main extension plane, the approximate or exactly rectangular conformation of the external heating element and the approximate or exactly rectangular conformation of the internal heating element could be correspondingly performed, where the approximate or exactly conformation Rectangular of the external heating element could be translatable to the approximate or exactly rectangular conformation of the internal heating element, for example, by a uniform reduction. In this way, a supported cooking battery can be heated and / or heated in a particularly advantageous manner.

Advantageously, when the heating unit is perpendicularly observed on the main extension plane, the innermost turn of the outer heating element and the outermost turn of the inner heating element have a distance of 0 in the direction of the main extension. At least 5 mm, preferably at least 1 mm, advantageously, at least 1.5 mm and, preferably, at least 2 mm. When the heating unit is perpendicularly observed on the main extension plane, the innermost turn of the outer heating element and the outermost turn of the inner heating element have a distance of at least 0.5 mm in the orthogonal direction, preferably, 1 mm minimum, advantageously, 1.5 mm minimum and, preferably, 2 mm minimum. In this way, uniform heating of the surface is made possible and / or the appearance of hot spots is prevented.
    Likewise, it is proposed that, when the heating unit is perpendicularly observed on the main extension plane, the innermost turn of the outer heating element and the outermost turn of the inner heating element present in the direction of the main extension a distance of 25 mm maximum, preferably 20 mm maximum, advantageously, 15 mm maximum and, preferably, 10 mm maximum. When the heating unit is perpendicularly observed on the main extension plane, the innermost turn of the outer heating element and the outermost turn of the inner heating element have a maximum distance of 25 mm in the orthogonal direction, preferably 20 mm maximum, advantageously, 15 mm maximum and, preferably, 10 mm maximum. In this way, a compact embodiment can be achieved. By observing the heating unit perpendicularly on the main extension plane, a flexible arrangement of the heating unit is made possible by its reduced extension, so that a great freedom of configuration can be achieved.
    By way of example, the internal heating element and the external heating element could be electrically connected in parallel with each other. The internal heating element and the external heating element could be separately activated. The first of the heating elements could be in an activated state, for example, in at least one operating state, and the second of the heating elements could be in a deactivated state in the same operating state. Preferably, the internal heating element and the external heating element are electrically connected in series. In at least one operating state, an electric heating current flows first through the first of the heating elements and then through the second of the heating elements. The heating elements can be activated and / or deactivated exclusively together. In at least one operating state, the internal heating element and the external heating element are both in an activated state, or both in a deactivated state. The heating unit could have at least one transition area through which the internal heating element and the external heating element could be separated from each other. By way of example, the transition area could have a width of at least 0.5 cm, preferably at least 1 cm and, advantageously, at least 2 cm. Preferably, the transition area has a width of less than 8 cm, preferably less than 6 cm and, advantageously, less than 5 cm. As an alternative, an embodiment is conceived in which there is no transition area, in which the heating element

    interior and the external heating element become directly the other. In the transition area advantageously lies at most one, preferably, at most average and, preferably, at most one quarter of a loop of at least one heating line of the heating unit. The heating unit has at least one and, advantageously, the heating line. In this way, the heating elements can be directed and / or operated in a particularly simple manner, thus being able to use a simple control algorithm. In this way, it becomes possible that the complexity of the programming is reduced and / or that the costs are low.
    Furthermore, it is proposed that the cooking device device has at least one sensor unit that is intended to detect at least one cooking parameter and which is arranged between the heating elements when the heating unit is perpendicularly observed on the extension plane principal. The term "sensor unit" includes the concept of a unit that has at least one detector to detect at least one cooking parameter and which is intended to emit a value that characterizes the cooking parameter, where the cooking parameter is advantageously a physical and / or chemical variable The cooking parameter could be, for example, a cooking state whereby different moments of a cooking process could be differentiated from each other Advantageously, the cooking parameter is a temperature. expression consisting in that the sensor unit is arranged "between" the heating elements includes the concept that, when the heating unit is perpendicularly observed on the main extension plane, there is at least one straight line that joins at least one point of the internal heating element and at least one point of the external heating element and cutting the sensor unit. When the heating unit is perpendicularly observed on the main extension plane, a straight line that leaves the sensor unit and follows in at least one direction always cuts at least one of the heating elements. Thus, great comfort can be achieved for the user. It is possible to use the free space in a reasonable manner, so that a compact realization can be achieved.
    Likewise, it is proposed that the cooking appliance device has at least one other heating unit that is performed analogously to the heating unit and which is provided in at least one operating state together with the heating unit for heating a Single cooking battery. In at least one operating state, the heating unit and the other heating unit form a common heating zone for heating at least one large cooking battery. The heating unit and the other heating unit are identical and, advantageously, not differentiable from each other. In this way, it is possible to heat even large cooking batteries optimally. Thanks to the approximate or exactly polygonal outer heating element of each of the two heating units, the heating units can be arranged compactly with respect to each other, so that optimized surface heating can be achieved preferably in comparison with two heating units adjacent to each other, each with two external heating elements that differ from an approximate or exactly polygonal conformation.

In an operating state, the heating unit 12a and the other heating unit 28a form a common heating zone. The other heating unit 28a is provided in an operating state together with the heating unit 12a to heat a cooking battery resting on it. The other heating unit 28a is performed analogously to the heating unit 12a. Therefore, only the heating unit 12a is described below and, in relation to the description of the other heating unit 28a, it refers to the exposed description of the heating unit 12a.
    Together with the heating unit 12a and the other heating unit 28a, the cooking device 10a has at least one additional heating unit 38a (see Figure 2). In the present embodiment, the cooking device 10a has two additional heating units 38a (see Figure 2). Only one of each of the objects present several times is accompanied by a reference symbol in the figures. Next, only one of the additional heating units 38a is described.
    When the additional heating unit 38a is perpendicularly observed on the main extension plane of the additional heating unit 38a, the additional heating unit 38a has an essentially oval, in particular, circular conformation. The additional heating unit 38a forms an autonomous heating zone to heat the cooking battery placed on top of it.

The sensor unit 26a is intended to detect a cooking parameter. In the present embodiment, the sensor unit 26a is provided to detect a temperature parameter. The cooking parameter is set as a temperature parameter.
    Figure 5 shows very simplified the result of a simulation of the temperature distribution of the cooking battery base 56a heated by the heating unit 12a, in a schematic representation. The denser the scratching, the hotter the corresponding area will be. It can be seen that the temperature distribution is essentially uniform without hot spots.
    Other embodiments of the invention are shown in Figures 6 to 9. The following descriptions are essentially limited to the differences between the examples of embodiment, where, in relation to components, characteristics and functions that remain the same, reference can be made to the description of the example of embodiment of Figures 1 to 5. For differentiation of the examples of embodiment, the letter "a" of the reference symbols of the embodiment example of Figures 1 to 5 has been replaced by the letters "b" to "d" in the reference symbols of the examples of embodiment of Figures 6 to 9. In relation to components indicated in the same way, in particular, as regards components with the same reference symbols, it is also possible to refer basically to the drawings and / or to the description of the embodiment example of Figures 1 to 5.
    Figure 6 shows an alternative cooking appliance device 10b. The cooking device 10b has two heating units 12b. Together with the heating units 12b, the cooking device 10b has two other heating units 28b. Each of the heating units 12b and each of the other heating units 28b form a common heating zone in an operating state.

    Figure 7 shows a heating unit 12c of an alternative cooking appliance device 10c. The heating unit 12c has an internal heating element 14c and an external heating element 16c essentially polygonal. When the heating unit 12c is perpendicularly observed on the main extension plane of one of the heating elements 14c, 16c, the density of the turns between the innermost turn of the inner heating element 14c and the outermost turn of the heating element outside 16c in the direction of the main extension 18c of one of the heating elements 14c, 16c essentially coincides with the density of the turns between the innermost turn of the inner heating element 14c and the outermost turn of the outer heating element 16c in an orthogonal direction 20c oriented essentially perpendicular to the direction of the main extension 18c.
    In the present embodiment, the ratio of the density of the turns between the innermost turn of the inner heating element 14c and the outermost turn of the outer heating element 16c in the direction of the main extension 18c and the density of the turns between the innermost turn of the inner heating element 14c and the outermost turn of the outer heating element 16c in the orthogonal direction 20c amounts to approximately 0.99.
    In this exemplary embodiment, the main extension 42c is smaller than the orthogonal extension 44c and amounts to approximately 72.3 mm. In this exemplary embodiment, the orthogonal extension 44c amounts to approximately 73 mm. The main extension 42c is smaller than the orthogonal extension 44c by approximately 0.7 mm.
    Figure 8 shows very simplified the result of a simulation of the power losses during the heating of a cooking battery heated by the heating unit 12c. The denser the scratching, the greater the power losses in the area in question. It can be seen that the power losses are essentially uniformly distributed and that there are no hot spots where the power losses are particularly high.
    Figure 9 shows a heating unit 12d of an alternative cooking appliance device 10d. The heating unit 12d has an internal heating element 14d and an external heating element 16d essentially polygonal. The heating elements 14d, 16d each have a main extension plane. In the present exemplary embodiment, the main extension plane of the internal heating element 14d and the main extension plane of the external heating element 16d are oriented essentially parallel to each other. Next, only one of the main extension drawings is described.
    The heating elements 14d, 16d each have an address of the main extension 18d. Next, only one of the addresses of the main extension 18d is described. The heating elements 14d, 16d in each case have longitudinal extensions 22d, 24d that are oriented essentially parallel to the direction of the main extension 18d.
    When the heating unit 12d is perpendicularly observed on the main extension plane, the external heating element 16d has an essentially rectangular shape. In this exemplary embodiment, the internal heating element 14d has an essentially rectangular shape when the heating unit 12d is perpendicularly observed on the main extension plane.
