    Description: The invention relates to a cooking device, comprising a top-side heating plate for supporting food to be cooked, wherein the heating plate is subdivided into a plurality of individually heatable heating zones. The cooking device is in particular a Teppan or Teppan Yaki device.
    EP 0 197 905 B1 discloses an apparatus for preparing foodstuffs, in particular by frying, comprising a plate and a heat source for heating the plate, the plate being made of a material of the composite material with an upper layer of corrosion-resistant material and one of the heat the lower layer of material having better heat conductivity than the material of the upper layer exposed to heat to expose the heat to the upper layer, the plate being of the type in which the upper layer is made of metal and one on the lower layer is sprayed on layer.
    WO 2009/007 781 A2 discloses a composite cooking structure for use as an upper grill plate comprising a plurality of thermally autonomous cooking zones and having a multi-layered structure including a top hard level part for providing a cooking surface.
    EP 1 553 863 B1 discloses a multi-purpose worktop for a stove or grill, comprising a multi-layer plate having a plurality of metallic layers attached to each other, of which at least the uppermost layer is made of sheet metal, wherein in the multi-layer plate a plurality of limited work areas are formed, which from each other Boundary zones are separated, in which of the metallic layers only or only the top layer of sheet metal is present, wherein in the work areas under the top layer, the other metallic layers are present. It is an embodiment that under at least one of the working areas an energy source for heating or cooling of the work area is attached.
    It is the object of the present invention, at least partially overcome the disadvantages of the prior art and in particular to provide a cooking appliance of the type in question, which is particularly reliable and versatile use. [0006] This object is achieved according to the features of the independent claim , Preferred embodiments are in particular the dependent claims.
    The object is achieved by a cooking device, comprising a top-side heating plate for top-side support of food, wherein the heating plate is divided into a plurality of individually heatable heating zones, wherein at least a first set of several contiguous adjacent heating zones of a second set of several contiguous adjacent Heating zones is completely surrounded.
    As a result, a particularly diverse distribution of the heating plate can be made in different temperature ranges. In particular, it is thus possible to heat at least one central or at least not edge-side region of the heating plate differently from an edge-side region, so that the edge regions of the heating plate represented by the second set are colder, for example, as with professional devices. This, in turn, advantageously makes it possible, after cooking on at least one heating zone of a first set, to move the food to at least one heating zone of the second set and to store it there, for example. to be kept warm. Also, this results in the advantage that the edge of the hot plate can be deliberately kept so low that the surrounding material is not damaged, while central areas can reach high operating temperatures. For example, standards for built-in appliances which limit wood temperatures to a wood furniture (e.g., a table top) accommodating the cooking appliance may be complied with in simple and non-heating plate operation. In addition, the flexible individual activation of the heating zones makes it possible to operate the heating plate with wide, laterally continuous zones, as was previously the case.
    The heating plate is in particular a plate which is flat or planar at its upper-side support surface for the food to be cooked at least substantially (i.e., except for possibly present structures which do not influence a cooking result, such as an edge-side channel). Such a heating plate is in particular no on its support surface for the food ribs having plate. However, the heating plate can basically also be a grill plate.
    The heating plate is provided for direct support of the food to be treated. The heating plate may e.g. be a steel plate and may be particularly suitable for roasting food. The steel may in particular be stainless steel, e.g. a Cr-Ni steel. The steel may be provided with a coating at least on its upper side, e.g. with a non-stick coating, hard chrome, ceramic, etc. The steel may also be uncoated. The heating plate may also be a multilayer plate or multilayer plate with layers of different material or multilayer material.
    That the heating plate is divided into a plurality of individually heatable heating zones, may be implemented so that the heating zones can be individually heated by them each associated, arranged under the hotplate general radiator. A radiator is basically not limited in its kind and may be e.g. a tubular heater, a flat thick-film heating, a plasma-sprayed heater, a gas burner, etc. include. An electrically powered heater may be preferred for versatility, a gas burner e.g. for its rapid temperature change.
    However, a locally limited to the respective heating zone heating may also be done inductively by appropriately arranged and controllable inductor coils. To reduce heat transfer from a heating zone to an adjacent heating zone, they may be thermally decoupled from each other, for example by thermal barriers introduced at the bottom of the heating plate between the heating zones, e.g. Heat seals, underside (especially non-continuous) slots, etc. These heat barriers are so narrow that their presence is virtually unnoticeable to a user of the cooking appliance and also a continuous hot plate smoothes out strong temperature jumps.
    That a set consists of several contiguously adjacent heating zones means, in particular, that each of the heating zones of a set is arranged adjacent to at least one other heating zone of that set. In other words, the heating zones of a set are arranged contiguously, except for possibly existing, practically negligible heat barriers between them.
    It is an embodiment that the heating zones of at least a first set are operable as a common heating zone. This allows a large coherent inner Summenheizzone. The fact that the heating zones of a set of several heating zones are operable as a common heating zone means, in particular, that they can be operated in the same way, in particular, they can be operated at the same temperature. So they practically form a uniform heating zone, namely the «Summenheizzone» composed of the individual heating zones of this set.
    It is still an embodiment that the common heating zone formed from the heating zones of a first set (ie the Summenheizzone of the first set) is operable at a higher temperature than the surrounding heating zones of the second set. As a result, an edge region of the heating plate represented by the second set is comparatively colder. This makes it possible to move food after preparation in an inner region of the heating plate edge, for example. to keep it warm. Also, there is the advantage that the edge of the heating plate can be kept cool so that surrounding material is not damaged.
    It is a further embodiment that a part of the heating zones of at least a first set and a part of the heating zones of the second set are operable as a common, strip-shaped heating zone. This can produce a conventional temperature behavior of a teppan. The temperature of different strip-shaped heating zones of the heating plate, which are arranged in particular parallel to each other, may be individually adjustable.
    It is yet a further embodiment that the heating zones form at least a first set a square, in particular rectangular, common outer contour. This outer contour may be specially shaped square. This embodiment allows an at least approximately equal distribution of the heating plate in different heating zones both in a horizontal position and in a vertical position.
    It is also an embodiment that the heating zones of at least a first set form a closed curved, in particular circular, common outer contour. This embodiment also allows at least approximately equal distribution of the heating plate in different heating zones both in a horizontal position and in a vertical position.
    It is also an embodiment that the cooking device comprises a first set of two heating zones and a second set of two heating zones. This gives the advantage of a particularly simple and inexpensive cooking device.
    It is also an embodiment that a first heating zone of the first set and an adjacent first heating zone of the second set may be formed and arranged in mirror image to a second heating zone of the first set and an adjacent second heating zone of the second set. This facilitates a division of the heating plate in two similar, in particular half, Summenheizzonen.
    It is still an embodiment that the heating zones are operable as independently operable halves of the heating plate or zusammenschalbar. The halves may e.g. (In particular from the perspective of the control panel) in the so-called. "Horizontal" arrangement or configuration may be arranged one above the other or may be arranged in the so-called. "Vertical" arrangement on the left side and right side.
    It is still an embodiment that a vertical and horizontal arrangement of the halves is selectively adjustable. This allows easy adaptation to different installation conditions.
    It is also an embodiment that the cooking device is a frying plate or grill plate, including a so-called. "Hot Plate" or a plancha. It is a particularly preferred development that the cooking device is a Teppan or Teppan Yaki device. With the Teppan food can be prepared directly at the table, but in a kitchen. The teppan may e.g. installed in a countertop or in a table top, in particular, be embedded. The Teppan may also be a portable Teppan. By means of a tepan, e.g. Food cooked in the form of Teppanyaki. Typical teppanyaki dishes are Okonomiyaki, Monjayaki and Yakisoba. However, the kind of the food to be cooked is basically not limited and may be e.g. also include fried eggs, vegetables, etc.
    The cooking appliance may be a household appliance or a professional device.
    The above-described characteristics, features and advantages of this invention, as well as the manner in which they are achieved, will become clearer and more clearly understood in connection with the following schematic
    Description of exemplary embodiments, which are explained in more detail in connection with the drawings. In this case, the same or equivalent elements may be provided with the same reference numerals for clarity.
    Fig. 1 shows a plan view of a cooking device with a heating plate according to a first embodiment;
    Fig. 2 shows a plan view of a cooking device with a hot plate according to a second Ausführungsbei game; and
    Fig. 3 shows a plan view of a cooking device with a hotplate according to a third embodiment.
    Fig. 1 shows a cooking device in the form of a teppan 1 according to a first embodiment. The Teppan 1 has a top-side heating plate 2, at the edge of a control panel 3 with at least one control element and possibly at least one display element (o. Fig.) Connects, here for example separated by a glass bar 4. The teppan 1, for example, in a Table top or built into a worktop. Cooked food is typically prepared directly on the heating plate 2.
    The heating plate 2 is a continuous steel plate, which underside, e.g. By radiator (not shown) in a plurality of independently operable or heated heating zones 5, 6, 7 and 8 is divisible. The division of the heating plate 2 into the heating zones 5 to 8 is implemented, for example, in such a way that the heating zones 5 to 8 can be individually heated by means of their respective heating elements (see Fig.) Arranged below the heating plate 2. In particular, a temperature of a heating zone 5 to 8 may basically be set individually.
    To reduce heat transfer from a heating zone 5 to 8 on an adjacent heating zone 5 to 8, they may be thermally decoupled from each other, for example, by below the heating plate 2 at a boundary between two heating zones 5 to 8 introduced thermal barriers W. These heat barriers W are so narrow that their presence is virtually imperceptible to a user of the Teppan 1.
    The operation of the heating zones 5 to 8 may be coordinated by means of a control device (not shown) of the teppan 1. The control device may in particular be adapted to operate the heating zones 5 to 8 in certain combinations. A desired combination may, for example, be predetermined by the user's choice of a particular operating mode. The user's choice may be e.g. be made by an input to the control panel 3.
    The heating zones 5 and 6 both have a rectangular basic shape and extend with their longer longitudinal sides 9, 10 over the entire width B of the heating plate 2. The heating zones 5 and 6 have at their adjoining longitudinal sides 9 a rectangular central cutout 11a or 11b. In the cutouts 11a and 11b, the corresponding rectangular shaped heating zones 7 and 8 are arranged. The equal shaped "inner" heating zones 7 and 8 may also be considered as a first set of heating zones, while the "outer" heating zones 5 and 6 may be considered as a second set of heating zones.
    The heating zones 5, 7 and the heating zones 6, 8 are formed in mirror image with respect to a horizontal center line M when viewed together. The heating zones 5, 7 form a rectangular first half and the heating zones 6, 8 form a rectangular second half of the heating plate 2. Both the first half and the two heating zones 5, 7 together and the second half or the two heating zones 6, 8 each extend over the entire width B of the heating plate 2, but only over half its height H. They are thus parallel to a longitudinal extent of the control panel 3. Their height H may be generally different.
    The orientation of the heating zones 5, 7 and the heating zones 6, 8 over the entire width B of the heating plate 2 or parallel to the control panel 3 can also generally be referred to as a "horizontal arrangement" of the heating plate 2. A 90 ° rotated arrangement with an extension of both sets 5, 7 and 6, 8 over the entire height H of the heating plate 2 (but eg only half the width B) can also be generally referred to as a "vertical arrangement" of the heating plate 2 , The heating zones 5 to 8 may be operated in particular in the following combinations or configurations: A) All the heating zones 5 to 8 are collectively or jointly controllable, e.g. All of them are operated at the same temperature. For a user, therefore, the sum of all heating zones 5 to 8 operated in the same way or the sum heating zones 5 to 8 as the entire heating plate 2 is. In other words, the first set of heating zones 7, 8 and the second set of heating zones 5, 6 operated together. The user may, for example, select this configuration on the control panel 3 and thereafter set the temperature of the heating zones 5 to 8 by means of a single setting. This can e.g. by explicitly setting the temperature above a setting of a cooking level (eg «0» (off) to «9» (hottest level) or «low», «medium» or «hot» etc.) or by setting a program (eg "Vegetables", "meat", "Okonomiyaki" etc.) happen. This configuration is indicated for the heating zones 5 to 8 in FIG. 2, wherein contiguous or jointly operable heating zones have the same hatching.
    B) All heating zones 5 to 8 are individually controllable or can be operated individually. The user may do this at the e.g. 1, the temperature (directly, via a cooking stage, etc.) shown in Fig. 1 for each of the heating zones 5 to 8 set individually. This configuration is indicated for the heating zones 5 to 8 in FIG. 3, wherein heating zones 5 to 8 which can be operated independently or separately have a mutually different hatching.
    C) The heating zones 5, 7 and the heating zones 6, 8 (corresponding to each half 5, 7 or 6, 8 of the heating plate 2) can each be operated jointly or coherently, in particular in the sense of being practically indistinguishable by a user Sumheizheizzone 5, 7 and 6, 8. The user likes to set on the control panel 3, the temperature of each of the halves 5.7 and 6.8 (directly, via a cooking stage, etc.) separately. This configuration is indicated for the heating zones 5 to 8 in FIG. 4, wherein contiguous or jointly operable heating zones have the same hatching.
    D) The first set of heating zones 7, 8 and the second set of heating zones 5, 6 are each operable continuously, in particular in the sense of an "inner" Summenheizzone 7, 8 or an "outer" Summenheizzone 5, 6. Both Summenheizzonen 5, 6 and 7, 8 have a rectangular outer contour. The user may set the temperature of the "inner" Summenheizzone 7, 8 and the "outer" Summenheizzone 5, 6 separately on the control panel 3. In particular, a temperature T1 of the inner cumulative heating zone 7, 8 may be higher than a temperature 12 of the outer cumulative heating zone 5, 6. This configuration is indicated for the heating zones 5 to 8 in FIG. 5, wherein contiguous heating zones have the same hatching ,
    Fig. 6 shows a plan view of an alternative heating plate 12 of the teppan 1, wherein the inner heating zones 13 and 14 of a first set now have no rectangular outer contour, but each having a semicircular outer contour. Accordingly, the recesses 15 of the second set of outer heating zones 16 and 17 also have a semicircular outer contour. The common sum heating zone of the first set of internal heating zones 13 and 14 is circular.
    The heating zones 13, 16 and the heating zones 14, 17 are further mirror images of each other when viewed in relation to the center line M and form a rectangular first half and a rectangular second half of the heating plate 12. The teppan 1 with the heating plate 12 can be operated analogously to a Teppan 1 with the heating plate 2.
    Fig. 7 shows a plan view of another possible heating plate 22 of a teppan 1. The heating plate 22 corresponds to the heating plate 2 with a further mirror image subdivision of the heating zones along a vertical center line M2. The heating plate 22 in this case has a first set of rectangular inner heating zones 23, 24, 25 and 26, which together can form a rectangular inner sum heating zone 23 to 26, of which each of the heating zones 23 to 26 forms a quadrant. A second set of outer heating zones 27, 28, 29 and 30 has a rectangular outer contour as sum heating zone 27 to 30. The outer heating zones 27, 28, 29 and 30 are also arranged in the manner of quadrants. Each of the outer heating zones 27 to 30 has a recess 31 for a respective inner heating zone 23 to 26 in its corner facing the center O of the heating plate 22.
    The heating zones 23 to 30 may be operated in particular in the following combinations or configurations: E) All heating zones 23 to 30 are collectively or jointly controllable, e.g. They are all operated at the same temperature (see figure, analogous to configuration A). For a user so the entire heating plate 2 can be operated uniformly.
    F) All heating zones 23 to 30 are analogous to configuration B individually controlled or can be operated individually (o. Fig.).
    G) The heating zones 23, 24, 27 and 28 corresponding to an upper half of the heating plate 22 and the heating zones 25, 26, 29 and 30 corresponding to a lower half of the heating plate 22 are each operable together, in particular in the sense of a by a user virtually indistinguishable total heating zone. The user may set the temperature of each of the halves 23, 24, 27 and 28 or 25, 26, 29 and 30 (directly, via a cooking stage, etc.) on the control panel 3 separately. This configuration G is indicated in FIG. 8, wherein contiguous or jointly operable heating zones have the same hatching. Configuration G practically corresponds to configuration C of FIG. 4 and may also be referred to as a "horizontal configuration".
    H) The one - in relation to the vertical center line M2 - left half of the heating plate 22 corresponding heating zones 23, 26, 27 and 30 and a right half of the heating plate 22 corresponding heating zones 24, 25, 28 and 29 are each common operable, in particular in the sense of a virtually no differentiable Summenheizzone by a user. The user may set the temperature of each of the halves 23, 26, 27 and 30 or 24, 25, 28 and 29 (directly, via a cooking stage, etc.) on the control panel 3 separately. This configuration G is indicated in FIG. 9, wherein coherently or jointly operable heating zones have the same hatching. Configuration H may also be referred to as a "vertical configuration".
    The horizontal configuration and the vertical configuration may be optionally adjustable by a user or a service technician in particular.
    I) The first set of heating zones 23 to 26 and the second set of heating zones 27 to 30 are each operable in a continuous manner, in particular in the sense of an "inner" Sumheizheizzone 23 to 26 or an "outer" Sumheizheizzone 27 to 30. Both Sumheizheizzonen 23 to 26 and 27 to 30 have a rectangular outer contour. The user may set the temperature of the inner Summenheizzone 23 to 26 and the outer Summenheizzone 27 to 30 separately on the control panel 3. In particular, such that a temperature T1 of the inner cumulative heating zone 23 to 26 may be higher than a temperature T2 of the outer cumulative heating zone 27 to 30. This configuration I is in
