COOKING SYSTEM AND METHOD OF OPERATING

Description

[0001] The present invention relates to a cooking system comprising at least one hob device, at least one piece of cooking utensil, at least one operating device with at least one operating element, and at least one communication device. Communication between the hob device and the cookware is possible by means of the communication device. The hob device comprises at least one support surface for the cookware and at least two induction devices arranged beneath the support surface, which can be controlled individually and / or together as a cooking zone by means of the operating device, depending on the position of the cookware. The present invention also relates to a hob device and a piece of cooking utensil for such a cooking system, and furthermore to a method for operating such a cooking system.

[0002] Various types of cooktops have become known, which generally comprise several separately controllable cooking zones. For example, induction cooktops have several induction coils located below the surface for pots and pans, allowing cookware placed above these induction coils to be heated.

[0003] In addition to induction hobs with fixed cooking zones, full-surface induction hobs have also become popular, which do not have predefined cooking zones but instead combine induction coils to form cooking zones in order to achieve particularly flexible usage.

[0004] However, with such cooktops without fixed cooking zones, there is generally no direct mapping of a cooking zone to a control option. Since a direct spatial mapping is not always intuitive, assistance in matching cooking utensils and cooking vessels can be helpful.

[0005] The same problem of a lack of intuitive allocation of controls to cookware also exists with so-called fully integrated cooktops. In such cooktops, the installation space is provided by the work surface. The cooktop's power electronics are located below the work surface or countertop. Here, too, there are no markings for cooking zones.

[0006] Various solutions have been proposed in the prior art. For example, DE 10 2014 207 261 B4 describes a luminous line connecting coils under a cooking utensil to the corresponding control element. However, such a connection between the cookware and the control element is relatively inflexible and cannot be used with fully integrated cooktops, as the appearance of the work surface should generally not be altered or changed as little as possible.

[0007] The document EP 3 096 586 A1 shows a generic solution for the assignment of a cooking utensil to a control element of a hob user interface.

[0008] The document WO 2019 012 354 A1 discloses a cooking utensil in whose immediate vicinity, in particular on the wall of the cooking utensil, display means are provided which inform the user about the positioning of the cooking utensil relative to a heating element.

[0009] The document DE 10 2012 216 719 A1 shows a cooking utensil with an operating and display device on the handle. The use of this operating and display device makes input and display devices on the hob obsolete.

[0010] The document EP 1 742 144 A1 shows a projection device for displaying the operating and display means of a hob.

[0011] The use of a rotatable input device on a hob is known from document EP 2 708 818 A2.

[0012] It is the object of the present invention to improve the assignment of cookware to an associated control element and to provide a simple and reliable display.

[0013] This object is achieved by a cooking system having the features of claim 1, by a cookware having the features of claim 11, by a hob device having the features of claim 12, by an operating device having the features of claim 13, and by a method for operating the cooking system having the features of claim 14. Preferred developments of the invention are the subject of the dependent claims. Further advantages and features of the invention will become apparent from the exemplary embodiments.

[0014] The cooking system according to the invention comprises at least one hob device, at least one piece of cookware, at least one operating device with at least one operating element, and at least one communication device. Communication between the hob device and the cookware is possible via the communication device. The hob device comprises at least one support surface for cookware and at least two induction devices arranged below the support surface, which can be controlled individually and / or together as a cooking zone using the operating device, depending on the position of the cookware.The operating device comprises at least one display device and the cookware comprises at least one display device, wherein the cookware is assigned to the operating element by at least temporarily displaying at least one identical and / or corresponding property on the display devices.

[0015] The hob device is designed in particular as a surface induction hob and preferably as a fully integrated surface induction hob. In this case, in such hobs, a plurality of induction devices or induction coils are preferably provided below a base for cooking utensils, which can be combined to form cooking zones as required, so that optimal heating of the cookware can be achieved. In such hobs, in particular, no fixed cooking zones are provided and accordingly they are not indicated on the base. This is particularly the case when a fully integrated hob is provided. Fully integrated hobs are preferably integrated into an existing work surface and are therefore not immediately visible. In particular with such hobs, the cooking system according to the invention considerably simplifies operation andsetting a power level for a specific cookware on the surface.

[0016] The operating device is preferably integrated into the hob or assigned to the hob. Depending on the design, however, it is preferred that a separate operating device be provided, via which the hob and, depending on the design, other appliances can be operated.

[0017] The fact that the operating device can control the induction devices combined to form a cooking zone means, in particular, that a power level can be set using the operating element. The hob device preferably comprises at least one control device, which, in particular taking into account pot position detection, for example, via the communication device, combines one or more induction coils completely and / or partially to form a variable cooking zone. The operating device can then be used, for example, to set the power level of the induction devices of a cooking zone.

[0018] The communication device preferably comprises at least one receiving device and at least one transmitting device. It is particularly preferred that the communication device can be used to determine the position of the pot or the position of the cookware on the support surface. Furthermore, it is preferred that the communication device ensures that identical or corresponding properties are displayed on the display devices.

[0019] According to the invention, an identical number and / or an identical shape and / or an identical symbol is displayed on the display device of the cookware and on the display device of the operating device as the same or corresponding property. This allows a control element to be clearly assigned to a specific piece of cookware on the installation surface.

[0020] If there are several control elements and / or several cookware items, an assignment can then be made based on the different properties.

[0021] If only one control element is provided for several cooking zones and / or cookware, the display device of the control device can preferably be provided so that the different and / or corresponding properties of the cookware can be selected or switched through in order to select a cooking zone to be actively controlled for a specific cookware.

[0022] The cooking system according to the invention offers many advantages. In particular, it is possible to enable a user to clearly assign a control element to a specific item of cookware, even with surface induction cooktops and / or fully integrated cooktops with variable or unmarked cooking zones.

[0023] This provides intuitive and easy assistance to users in setting the cooking process for a specific item of cookware using the control panel. This eliminates the need for lighting elements built into or on the surface, which significantly limit the flexibility of the display and are also not possible or desirable with cooktops fully integrated into a worktop.

[0024] Furthermore, a separate display device in the control unit and the cookware makes it possible to configure the control unit separately from the cooktop unit or as an external control unit. In particular, this also allows control via an app or similar device, in which certain identical or corresponding properties are displayed to assign a cookware item to a control element.

[0025] The operating device is preferably assigned to the hob device. It is particularly preferred that the operating device is included in the hob device or is the operating device of the hob. In such an embodiment, the operating device of the hob and / or an operating element of the operating device includes the display device, so that corresponding and / or identical properties can be displayed.

[0026] Particularly preferably, the operating device is designed as a separate assembly. In this case, the operating device can be designed, in particular, as a separate assembly and / or a separate assembly can be integrated. For example, the operating device can be provided as the sole or as an additional separate control, for example, on a mobile device and / or on a smartphone, a tablet, or a similar device. In particular, the operating device is then integrated into an app or designed as an app.

[0027] In expedient embodiments, the display device of the cookware and / or the display device of the operating device comprises at least one lighting device with at least one lighting element. Thus, with such an embodiment, a cookware item can be assigned to a specific operating element, for example, via a light signal. It is particularly preferred that different light colors and / or a different number of lighting elements code different cookware items.

[0028] In expedient embodiments, the lighting device comprises at least one light source, wherein the lighting element is preferably designed as a light-coupling element. For example, a light source can be provided separately from the lighting element or the light-coupling element, so that the lighting element can also be provided in locations with limited installation space. The connection between the light source and the lighting element or the light-coupling element can preferably be established via at least one optical fiber or the like.

[0029] Preferably, the display device of the cookware and / or the display device of the operating device comprises at least one projection device. Such a projection device enables, in particular, the projection of colors, shapes, numbers, and / or images onto a projection surface. For example, in the case of a cookware item, the projection surface may be the surface on which the cookware is placed. This makes it possible, in particular, to project at least one property or symbol onto the hob. The lighting element can preferably be part of the projection device and / or provide the projection device.

[0030] Particularly preferably, the display device of the cookware and / or the display device of the operating device comprises at least one display. Even with such an embodiment, identical and / or corresponding properties for coding at least one cookware item to a control element can be displayed. Particularly with a display, the control elements can also be provided as softkeys or the like.

[0031] In expedient developments, the luminous element is arranged or provided in at least one handle and / or on at least one wall of the cookware and / or on at least one lid of the cookware. It is particularly preferred that the luminous element be provided as a luminous strip or elongated luminous strip, as a point-shaped luminous element, as several point-shaped or strip-shaped luminous elements, and / or the like. For example, the different colors of a luminous strip can be used to assign a control element. Depending on the design, assignment can also be based on the number of illuminated elements.

[0032] Preferably, the control element is designed as a control knob, with the display device being provided on the control knob. In this case, for example, a fixed or permanently mounted knob and / or a removable knob can be provided, with an illuminated ring being provided on the knob as the illuminated element or display device.

[0033] Preferably, only one control element is provided for multiple cooking zones or multiple cookware items, whereby a user can control the individual cooking zones or cookware items by selecting a specific displayed property. It is particularly preferred that a user can select the different properties and thus control the different cookware items via intuitive operation, allowing easy adjustment of performance parameters for a cookware item.

[0034] Preferably, the cookware has a double-walled wall at least in sections, with the indicator device of the cookware being arranged at least partially in the double-walled wall. Thus, in particular, with such a design, it is possible to accommodate the indicator device in the cookware in the most space-saving manner possible.

[0035] Particularly preferably, the indicator device of the cookware is arranged at least partially in at least one handle of the cookware. Depending on the design, the indicator device can also be arranged in the lid and / or another accessory part of the cookware. With such a design, the indicator device can be advantageously accommodated.

[0036] In expedient developments, at least one light source is provided in at least one handle of the cookware, and at least one light-coupling element is provided in and / or on at least one wall of the cookware and / or on at least one lid of the cookware. The light source is connected, in particular, to the luminous element or the light-coupling element by means of a light guide or the like. With such a configuration, it is particularly possible to accommodate the light source separately from the light-coupling element, with sufficient space being available for the light source in a handle, depending on the configuration of the cookware.

[0037] In expedient embodiments, at least one performance parameter of the associated cooking zone can be displayed using the display devices of the cookware. This can then be used, for example, to code a performance parameter using the number of light elements. If the display device is designed as a display, for example, on the handle of a cookware item, a performance parameter, such as the power level, can also be displayed here. Even if the display device includes a projection device, a performance parameter can advantageously be projected onto the installation surface in addition to the coding for a specific control element.

[0038] Preferably, the cookware is suitable and designed to provide energy via energy harvesting.

[0039] The cookware according to the invention is designed for use in a cooking system as previously described.

[0040] The cooking hob device according to the invention is designed for use in a cooking system as previously described.

[0041] The operating device according to the invention is designed for use in a cooking system as previously described.

[0042] The cookware and cooktop device according to the invention also offer the advantages already described above for the cooking system. In particular, a user is shown a clear assignment of cookware to a control element, so that, particularly with surface induction cooktops or a cooktop fully integrated into a work surface, intuitive control of the cooking processes can be achieved even with multiple cookware.

[0043] The method according to the invention is suitable for operating a cooking system as described above. The cookware is assigned to a control element by at least temporarily displaying at least one identical and / or corresponding property on the display device of the operating device and the display device of the cookware.

[0044] The method according to the invention also offers many advantages. In particular, the user is clearly and easily informed about which control element controls which cooking zone for which cookware, allowing intuitive and clear control of performance parameters for specific cookware.

[0045] Preferably, only one control element is provided for several cooking zones, with the user selecting a specific item of cookware to be controlled by selecting a specific property. In this case, a knob or a control knob can be provided as the control element, on which only the cooking zone to be actively controlled or the property of this cooking zone is displayed. For example, by tilting, pressing and / or turning, it is possible to select between different properties and thus between the operation of different cooking zones. Even if a display is provided as the display device, a specific cooking zone or a specific item of cookware can be selected by selecting a specific property.

[0046] Further advantages and features of the present invention will become apparent from the embodiments which are explained below with reference to the accompanying figures.

[0047] The figures show: Figure 1 shows a purely schematic representation of an embodiment of a cooking system according to the invention in a perspective view; Figure 2 shows a purely schematic representation of a further embodiment of a cooking system according to the invention; Figure 3 shows a purely schematic representation of a next embodiment of a cooking system according to the invention; Figure 4 shows a purely schematic representation of another embodiment of a cooking system according to the invention; Figure 5 shows a purely schematic representation of a further embodiment of a cooking system according to the invention; Figure 6 shows a purely schematic representation of an embodiment of a cookware according to the invention in a side view; Figure 7 shows a purely schematic representation of a further embodiment of a cookware according to the invention in a side view;Figure 8 shows a purely schematic representation of another embodiment of a cookware according to the invention in a side view; and Figure 9 shows a purely schematic representation of a next embodiment of a cookware according to the invention in a side view.
