Description

The invention relates to a method for operating a cooking system according to claim 1, a hob for carrying out such a method according to claim 6, and cooking utensils for carrying out such a method according to claim 7.

The trend in domestic cooking continues to make the implementation of the cooking processes easier, more convenient and / or safer for the user with regard to the desired cooking result. This can be supported in that complete automatic programs or assistance functions are made available to the user, which are intended to relieve the user of part of the execution or even the complete execution of the cooking process. A cooking process can also be supported, for example, by the hob and / or by a mobile device, in that the cooking process is followed there, displayed to the user and the next actions in the recipe sequence are displayed or appropriate instructions are given to the user.

The hobs should also visually disappear further and further from the kitchen. This also includes making the control elements of the hobs increasingly inconspicuous or making them disappear completely. This can lead to the controls and the display elements of the hobs being relocated to the cookware. It may therefore be necessary or at least desirable for information to be able to be exchanged between the cookware and the hob. This can include the transmission of instructions as well as of measured quantities.

The EP 1 280 443 B1 describes an electronic frying pan system having a pan for preparing food, a handle connected to the pan for moving or manipulating the pan, one or more temperature sensors connected to the pan to generate signals that indicate a pan characteristic or a plurality of pan characteristics, and display electronics, which are connected to the sensors and are provided in or with the handle, in order to provide at least one indication or display of the pan characteristics to a user of the pan. The display electronics have a processor to process the signals to associate food characteristics corresponding to food being prepared in the pan, and the display electronics include a user interface for selecting one of a plurality of food characteristics.

The DE 20 203 566 U1 describes a cooking vessel with a handle with sensor electronics to which at least one temperature sensor is connected. The temperature sensor is provided on the handle. The handle is designed to be removable from the cooking vessel together with the temperature sensor. When the handle is attached, the temperature sensor extends to the wall material of the cooking vessel in a temperature-transmitting manner. The handle or the sensor system have a display, preferably an LC display, which is designed in particular to display various states or operating processes of the cooking vessel. The handle or the sensor system have a control, preferably with a microprocessor, with cooking programs being contained in particular in the microprocessor. Switching means or the like for actuating the temperature display or a sensor system are provided on the handle. A power supply, preferably with a removable battery or an accumulator, is provided in the handle.

The EP 2 361 538 A1 describes an electronic pan having a pan body, a handle and a power generation based on the difference in the temperature unit and a temperature measuring unit. The power generation based on the difference in the temperature unit consists of a semiconductor cooling disk, a voltage-increasing and regulated electronic module and an energy storage unit. The temperature measuring unit consists of a temperature sensor, a microprocessor, a circuit board and a liquid crystal display for displaying the temperature. The temperature sensor is arranged directly under the shell body. The circuit board is arranged in the chamber of the handle. The semiconductor cooling disk connected to the pan body is provided inside the chamber at the connection of the handle and the pan body. The other surface of the semiconductor cooling disk is firmly contacted with metallic heat exchanger disks. The power generation due to the difference in the temperature unit, the temperature measuring unit and the liquid crystal display is connected to the circuit board, respectively.

The disadvantage of all these electronic cooking utensils is that very complex electronics must be arranged in the handle of the cooking utensils in order to be able to implement the functions. This can lead to corresponding costs for the development, manufacture and assembly of the electronics. It may also be necessary to arrange the electronics in the handle because of their space requirements, which can prevent the use of such electronics in cookware without a handle and limit it to pans.

In any case, the electronics must also be protected, for example, from moisture, which can make appropriate sealing measures necessary, in particular around the cookware To make it dishwasher-safe. Alternatively, the handle can be removed by the user, but this can mean additional work for the user.

The invention thus poses the problem of providing a cooking system so that electronic support can be made possible for the user on the cooking utensil with less effort than previously known. In particular, simplified electronic display options are to be created on the cookware. At least one alternative to known cooking systems or cooking utensils is to be provided.

According to the invention, this problem is solved by a method for operating a cooking system with the features of claim 1, by a hob with the features of claim 6 and by a cookware with the features of claim 7. Advantageous refinements and developments of the invention emerge from the following subclaims.

• • Erzeugen einer Ausgabeinformation seitens des Kochfelds,
• • Aussenden der Ausgabeinformation von dem Kochfeld an das Gargeschirr,
• • Empfangen der Ausgabeinformation des Kochfelds seitens des Gargeschirrs und
• • Ausgeben der Ausgabeinformation des Kochfelds durch das Gargeschirr.

The invention thus relates to a method for operating a cooking system, preferably an inductive cooking system, the cooking system having a hob and cooking utensils, the method comprising the steps:

• • Generating output information from the hob,
• • Sending the output information from the hob to the cookware,
• • Receiving the output information of the hob from the cookware and
• • Output information for the hob through the cookware.

In other words, the generation of output information from the cookware, as previously known, can be shifted to the hob. This can usually take place there without additional expense in terms of electronics or data processing, since such hobs usually have sufficiently powerful electronics or data processing anyway to also generate output information relating to the cookware. At the same time, however, it is possible to dispense with correspondingly powerful electronics or data processing on the part of the cooking utensil, which can reduce the costs of the cooking utensils, require less installation space there and / or lower the energy consumption of the cooking utensils.

The electronics required on the cookware to output the output information from the hob can be reduced to a transmitter / receiver unit and a display element. Possibly. Simple, compact, inexpensive and / or energy-saving electronics can be used there to operate the transmitter / receiver unit and the display element such as a liquid crystal display and to forward the output information received from the hob from the transmitter / receiver unit to the display element. According to the invention, this can be done much more easily and / or more cost-effectively than previously known.

• • Erfassen einer Sensorinformation seitens des Gargeschirrs,
• • Aussenden der Sensorinformation von dem Gargeschirr an das Kochfeld und
• • Empfangen der Sensorinformation des Gargeschirrs seitens des Kochfelds,

wobei das Erzeugen der Ausgabeinformation seitens des Kochfelds in Abhängigkeit der empfangenen Sensorinformation des Gargeschirrs erfolgt.According to one aspect of the invention, the further preceding steps take place:

• • Acquisition of sensor information from the cookware,
• • Sending the sensor information from the cookware to the hob and
• • Receipt of the sensor information from the cookware by the hob,

wherein the generation of the output information on the part of the hob takes place as a function of the received sensor information of the cooking utensil.

In other words, processing or use of sensor information, which can be detected on the cookware, for example by means of a sensor element such as a temperature sensor, can be shifted from the cookware to the hob or its electronics or data processing. This can also offer the advantages described above if sensor information is to be recorded from the cookware.

• • Erfassen einer Bedieneingabe seitens des Gargeschirrs,
• • Aussenden der Bedieneingabe von dem Gargeschirr an das Kochfeld und
• • Empfangen der Bedieneingabe des Gargeschirrs seitens des Kochfelds,

wobei das Erzeugen der Ausgabeinformation seitens des Kochfelds in Abhängigkeit der empfangenen Bedieneingabe des Gargeschirrs erfolgt.According to a further aspect of the invention, the further preceding steps take place:

• • Acquisition of an operator input from the cookware,
• • Sending the operator input from the cookware to the hob and
• • Receiving the operator input for the cookware from the hob,

wherein the generation of the output information on the part of the hob takes place as a function of the received operating input of the cooking utensil.

In other words, the processing or use of operating inputs, which can be made by the user on the cooking utensil, for example by means of an operating element such as a button, can be shifted from the cooking utensil to the hob or its electronics or data processing. This can also offer the advantages described above if operating inputs from the cookware are to be recorded.

According to a further aspect of the invention, the output information of the hob is output by the cooking utensil by means of an optical display element. Such an optical display option can be created simply, compact, inexpensive and / or with low energy consumption by means of a light element such as an LED, which can light up or flash in one or more colors, for example, or by means of a graphic display element such as a liquid crystal display. At the same time, simple information, including numerical values and the like, can be displayed to a user on the cookware in this way.

According to a further aspect of the invention, a display element, an operating element and / or a sensor element of the cooking utensil is activated in response to a successful pairing of the hob and cooking utensils. As a result, one, several or all of these elements on the cooking utensil can be activated as soon as a pairing between the hob and cooking utensils has been established and these elements can thus be used to avoid remote action. If in this case, for example, the control element is illuminated or information is shown by the display element, the successful pairing of the hob and cookware can also be displayed in this way to the user.

The invention also relates to a hob for performing a method as described above. In this way, a hob can be provided in order to enable the previously described method according to the invention with its properties and advantages to be carried out.

The invention also relates to cooking utensils for carrying out a method as described above. In this way, cooking utensils can be provided in order to enable the previously described method according to the invention with its properties and advantages to be carried out.

• 1 eine schematische Darstellung eines Kochsystems zur Durchführung eines erfindungsgemäßen Verfahrens von Vorne; und
• 2 ein Ablaufdiagramm eines erfindungsgemäßen Verfahrens.

An embodiment of the invention is shown purely schematically in the drawings and is described in more detail below. It shows

• 1 a schematic representation of a cooking system for performing a method according to the invention from the front; and
• 2 a flow chart of a method according to the invention.

The above figures are viewed in Cartesian coordinates. A longitudinal direction X extends, which can also be referred to as depth X or length X. A transverse direction (not shown), which can also be referred to as the width, extends perpendicular to the longitudinal direction. A vertical direction extends perpendicular to both the longitudinal direction X and the transverse direction Z which also called height Z can be designated.

1 shows a schematic representation of a cooking system 1 , 2 for carrying out a method according to the invention from the front. The cooking system 1 , 2 consists of a hob 1 as well as from a cookware 2 . The cookware 2 is to improve the displayability of the 1 in height Z above the hob 1 arranged.

The stove top 1 is as an inductive hob 1 executed and has several hotplates 11 on, of which only one hotplate 11 in the 1 is shown by way of example. The stove top 1 has a cover 10 in the form of a glass plate 10 on which the surface of the hob 1 forms on which cookware 2 on the hotplates 11 can be turned off. Under every hotplate 11 is a heating element 12th provided, which in this case an induction coil 12th is. The stove top 1 also has a transmitting / receiving unit 13th on, which is able to receive wireless signals, for example from the cookware 2 to receive as well as wireless signals, e.g. to the cookware 2 to send out. Both the induction coil 12th as well as the sender / receiver unit 13th are signal-transmitting with a control unit 14th of the hob 1 connected, which process signal or data, generate as well as the induction coil 12th and the transmitter / receiver unit 13th can operate or control.

The cookware 2 is a pan in this case 2 , which have a cookware body 20th as a pan body 20th has, on which a handle element laterally 21 or a handle 21 is arranged. In the bottom of the pan body 20th is a sensor element 24 in the form of a temperature sensor 24 provided so that a temperature of the bottom of the pan body 20th can be detected by sensors at this point. The handle 21 has a display element 22nd in the form of a liquid crystal display 22nd on. Furthermore, the handle 21 a control element 23 in the form of a button 23 on. Furthermore, the handle 21 a transmitter / receiver unit 25th on. The display element 22nd , the control element 23 , the sensor element 24 as well as the sender / receiver unit 25th are each transmitting signals with a control unit 26th connected (not shown).

The control unit 26th of the cookware 2 , which also acts as a signal processing unit 26th can be referred to, according to the invention is comparatively simple, compact, inexpensive and energy-saving and is only capable of the display element 22nd , the control element 23 , the sensor element 24 as well as the sender / receiver unit 25th to coordinate with each other. In other words, the control unit 26th of the cookware 2 essentially just the display element 22nd , the control element 23 , the sensor element 24 as well as the sender / receiver unit 25th operate and sensor information from the sensor element 24 as well as input from the control element 23 received and this to the sender / receiver unit 25th forward so that the sender / receiver unit 25th the sensor information or operator inputs then, for example, to the hob 1 can send. Output information from the hob, for example, can be used in the opposite direction 1 by means of the transmitter / receiver unit 25th detected and via the control unit 26th of the cookware 2 to the display element 22nd be forwarded to be displayed to a user there.

The actual processing of the sensor information or operator input from the cookware 2 , which from the sender / receiver unit 13th of the hob 1 can be detected, takes place in the control unit 14th of the hob 1 . The sensor information or operating inputs for the cookware can be entered there 2 Among other things, it can be used to generate the output information, which is then sent from the hob 1 by means of its transmitter / receiver unit 13th to the cookware 2 can be sent.

• In Reaktion auf ein erfolgtes Pairing von Kochfeld 1 und Gargeschirr 2 kann ein Aktivieren 000 des Anzeigeelements 22, des Bedienelements 23 und des Sensorelements 24 des Gargeschirrs 2 erfolgen. Dies kann beispielsweise dem Benutzer dadurch angezeigt werden, indem z.B. das Bedienelement 23 beleuchtet wird und das Anzeigeelement 22 eine Information anzeigt.

This can be done by means of a method according to the invention, as in the flowchart of FIG 2 shown as follows:

• In response to the hob being paired 1 and cookware 2 can activate 000 of the display element 22nd , the control element 23 and the sensor element 24 of the cookware 2 respectively. This can for example be displayed to the user by, for example, the control element 23 is illuminated and the display element 22nd displays information.

A capture now takes place 100a sensor information from the cookware 2 by means of the sensor element 24 eg in the form of a current temperature value, this sensor information can be sent out 200a from the cookware 2 to the hob 1 transmitted and there by receiving 300a the sensor information of the cookware 2 side of the hob 1 can be obtained.

On the hob 1 can now on the part of its control unit 14th a generating 400 output information as a function of the sensor information received from the cookware 2 take place by, for example, the sensor information of the temperature sensor 24 of the cookware 2 is converted into a temperature value. This temperature value can now be used as output information on the part of the hob 1 by sending it out 500 from the hob 1 to the cookware 2 transmitted and there by receiving 600 the output information of the hob 1 on the part of the cookware 2 can be obtained. By means of the display element 22nd of the cookware 2 can then output 700 the output information of the hob 1 through the cookware 2 done so that the user can see the current temperature of the cookware 2 on the handle 21 can be displayed.

In the case of an operator input by the user by means of the operator control element 23 can be compared to capturing 100b the operator input from the cookware 2 take place, which by means of sending 200b the operator input from the cookware 2 to the hob 1 transmitted and there by means of receiving 300b the operator input for the cookware 2 side of the hob 1 can be obtained. In this case, generating 400 the output information from the hob 1 depending on the operator input received from the cookware 2 and attached to the cookware as described above 2 transmitted and displayed there.
