It is the object of the present invention to overcome the disadvantages of the prior art, at least in part, and in particular to provide an improved possibility for preparing food at low temperatures on a hob.

This object is achieved according to the features of the independent claims. Preferred embodiments are in particular the dependent claims.

The object is achieved by a system comprising a cooking appliance with a hob for attaching at least one cookware and having at least one attachable to the hob cookware, wherein the cookware has at least one temperature sensor for detecting a temperature of food that is absorbed by the cookware ,

The cookware further comprises an electrical or electronic circuit which is connected to the at least one temperature sensor and which is adapted to receive and process at least one temperature signal of the temperature sensor. This circuit can also be referred to below as "pot electronics" without limiting the generality. The at least one temperature sensor thus detects the temperature of the food or the cookware and passes them to the (electrical or electronic) circuit of the cookware on.

The cookware also has a transmission device which is adapted to receive the temperature signal processed by the circuit (and possibly other data) and to transmit or forward it wirelessly to the cooking appliance. The transfer device of the cookware can advantageously also receive data.

The cookware further includes electrical supply means for supplying electrical power to its powered components (e.g., the circuit and / or the transmitter). The cookware is therefore an electrically operable cookware.

The cooking appliance has a transmission device (hereinafter also referred to as "receiving device" without limiting the generality) at least for receiving the temperature data transmitted by the transmission device of the cookware. The transmission device of the cooking appliance can also be set up to transmit signals or data.

The cooking appliance also has a circuit connected to the receiving device (hereinafter also referred to as "stove electronics" without restricting the general public) for setting an energy supply to at least one cookware. Among other things, the circuit is set up to regulate the temperature of the food by means of the transmitted temperature data.

This system has the advantage of providing a very accurate temperature control for cooktops that is accurate even at low temperatures (e.g., 80 ° C or 65 ° C or less). So a cooking result can be achieved particularly reliable. If, for example, additional food is added, the temperature sensor registers this, and the heating power is increased until the desired temperature is reached again and then keeps this setpoint temperature constant. For the customer, this means an advantageous cooking experience, since now a target temperature can be specified, which is then set and held automatically on the cooking appliance. There is now hardly any risk of overcooking or burning if the target temperatures are sensibly chosen. Also, the formation of a fat burning is now impossible because the cooking device when reaching a target temperature for frying (for example, 180 ° C) reduces the heating power and fat so that it can not be overheated.

The cookware is used to prepare cooked food received therein or of food (s) received therein. The cookware may for example be a pot, a roasting pan, a pan, a Dampfgaraufsatz etc.

The cooking appliance has in particular a hob. The cooking appliance may be a stand-alone cooking appliance or a hob / oven or a cook / back combination, e.g. a cooker.

The transmission device can be integrated into the circuit of the cookware (pot electronics) or the circuit can have a transfer function. The circuit and a module having the circuit can be made very small (e.g., in Surface Mount Technologist, "SMT") and have low power consumption.

It is a development that the circuit - advantageously sealed - is installed in a housing on a side wall of the cookware, so that a user is not disturbed by it. It is also a development that the circuit is installed in the handle of the cookware. This offers the advantage that even at high temperatures of the cookware, the circuit remains relatively cool.

It is an embodiment that the circuit is implemented in surface mount technology and as a module - in particular by means of a housing - tightly encapsulated, since this results in a compact design with low power consumption, easy installation with high protection against external influences ,

It is a further development that the at least one temperature sensor has at least one sensor element (for example a thermocouple or a PT100 temoperature sensor) fixedly connected to a bottom of the cookware. Alternatively or additionally, at least one temperature sensor can also be connected to a side wall of the cookware by pressure, adhesive bonding, clipping on, etc.

At least one temperature sensor can be arranged in a housing of the pot electronics. Also, at least one thermocouple, which is located in the cookware and immersed directly in the food therein, can be used. A temperature sensor can therefore sense the temperature of the food directly on the food or indirectly via a temperature of the cooking utensils.

The circuit and / or the transmission device may be located generally on the cookware and / or in the cookware.

The transmitter may transmit data, for example, over the air (e.g., using a Bluetooth standard or WLAN standard, etc.) or other suitable transmission techniques (e.g., infrared radiation, transformer coupling, etc.). The transmission device can transmit data unidirectionally or bidirectionally.

The electrical supply device may have an energy store such as a battery, an accumulator, a supercapacitor, etc. The electrical utility may alternatively or additionally be configured to receive energy wirelessly (e.g., in the form of an alternating magnetic field, solar energy, etc.). The wireless reception can be carried out, for example, by way of a transformer via a coil, by means of a design of the electrical supply device (and possibly the circuit) as an RFID element, by means of a solar cell, by means of a Peltier element, etc. The wireless power supply has the advantage that no battery change is required.

It is a development that the cookware has an electrical supply device in the form of a coil, which is designed for transformer coupling with a coil of the cooking appliance. In transformer energy transfer, the coil ("primary coil") in the cooking appliance may be operated with AC voltage to produce an AC magnetic field at the location of the cooker coil ("secondary coil"). This magnetic field induced in the secondary coil, which is advantageously located in the region of the bottom of the cookware, a voltage that can serve to supply the circuit, etc. of the cookware. This transformer power supply by means of two closely spaced coils has the advantage that results in a particularly finely adjustable energy transfer, which is particularly advantageous for treating food at low temperatures (up to about 80 ° C). Also, so electrical consumers such as the pot electronics, etc. can be integrated into the cookware, as a defined electrical power supply is provided. The cookware can then also be referred to as an "intelligent" electrically operated cookware.

The transformer power supply by means of two closely spaced coils has the further advantage that also the signal transmission from the cookware to the cooking appliance (and possibly also in the opposite direction) can be implemented by the supply signal, a corresponding communication signal is superimposed. So it is generally an embodiment that the at least one intended for transformer coupling coil of Cookware and / or the cooking appliance is provided both for energy transmission and for data transmission by means of the transformer coupling. The transmission device can thus use, in particular, coils for wireless data transmission, which are already present for the power supply of the cookware. Alternatively, the energy and signal transmission can also take place separately from the power supply via a transformer-coupled coil pair, which is provided only for data transmission.

So it is a development that the cooking appliance has one or more arranged under the cooktop coil (s), which serves for supplying energy to a set for transforming operation cookware and / or for transformatory data or signal transmission. In particular, the hob can have a plurality of cooking zones, wherein at least one cooking point is assigned at least one coil.

It is a general embodiment that the cooking appliance has a hob with at least one cooking point, which is associated with at least one cooking coil at least one coil for transforming energy transfer to a cooking appliance placed on the hob and at least one cookware has an electrical supply device in the form of a coil, the is designed for transformer coupling with a coil of the cooking appliance.

It is still an embodiment that at least one cooking point, which is associated with a coil, additionally associated with at least one heat-transmitting heating element. The heat-transmitting heating element serves to heat the cookware for heat treatment of food therein. The at least one heat-transferring heating element may e.g. a gas burner, an electrically operated resistance heating conductor, etc.

In particular, the cooking appliance can automatically detect whether the cooker is a cookware as described above or not. If this is the case, a temperature control can be provided or activated. If this is not the case, the cooking appliance can operate the cookware by means of a power setting, in particular provide only a power control for operation. So even conventional cookware, which are not electrically powered, can be heated.

In addition or as an alternative to the heat-transmitting heating element, it is also possible to provide at least one coil for inductive heating of the cookware by eddy currents and / or at least one halogen emitter. The heat-transmitting heating element, the inductive heating coil and / or the halogen radiator may also be collectively referred to as cookware heating means.

The received at the receiving device of the cooking device temperature data signal (which includes information about the current temperature) is used by the stove electronics of the cooking appliance to regulate a power supply or heating power to the cookware in order to maintain the cooking temperature at a set value. The heating power can also be gently heated by a user input for sensitive food. e.g. so that only a portion of the available heating capacity is used. The stove electronics can thus process the provided temperature signal and can have a corresponding control algorithm for temperature control by means of a control of the heating power.

It is a development that the system is set up to perform an automatic pan detection. So the cooking appliance can recognize on which hob a cookware is. This pot detection can be realized for systems with transformatory energy transfer, inter alia, as follows: If the cooking appliance is turned on, so for a short time at each hob, the respective associated coil ("cooktop coil") is turned on for energy. Each cookware located on a cooking station is now supplied with energy and can signal its existence to the cooking appliance by means of a signal transmission via the transmission device, e.g. by means of a transmission of temperature data. The stove electronics now knows on which hob a cookware with the appropriate circuit is. If the operator activates a specific hob, which the cooking appliance knows is not fitted with a cookware with a circuit on it, then this cooking hob is operated in normal operation with a power control.

In principle, the cooking appliance of each metallic cookware can be determined by an inductance measurement. For example, if the cooking appliance is switched on, the cooking appliance - e.g. by means of its stove electronics - check the inductance of its coils. If this deviates at least by a certain amount from the known inductance of the coil without thereon cooking utensils, it is assumed that there is a cookware on the corresponding hotplate.

It is still a further development that the cookware is adapted to transmit an identification number to the cooking appliance by means of the transmission device, in particular if the signal transmission is not carried out by transformation, so that the cooking appliance the assignment of a Cookware is allowed to a corresponding hotplate.

It is also a further development that the system, in particular its cooking appliance, has an automatic shutdown function. If, for example, the stove electronics detects that there is no metal on a hob or if a level of a received data signal falls below a predetermined limit, the heating power is automatically switched off.

It is also a further development that the system, in particular its cooking appliance, a "Topfschiebefunktion" has. For example, if it is recognized that a cookware is moved from one hob of the cooking appliance to another hob, the cooking parameters (eg, a set temperature) of the previous hob for the new hob are automatically taken, and the user only needs to activate the new hob so that it is operated with the "moved" cooking parameters.

• a) Reiskochen: Hierbei kann ein Temperatursprung, der auftritt, wenn das zum Reiskochen verwendete Wasser verdampft ist, mit hoher Genauigkeit erkannt werden. Anschließend kann von einem Kochmodus in einen Warmhaltemodus umgeschaltet werden.
• b) Steakprogramm: Hier kann die genaue Temperaturmessung dazu verwendet werden, Fleisch zunächst scharf anzubraten, und dann bei geringerer Temperatur durchzubraten.
• c) Kochen von Beilagen wie Nudeln, Kartoffeln oder Gemüse bei konstanter Temperatur oder mit einem Dampfgaraufsatz.
• d) Teig gehen lassen.
• e) Würste erwärmen und warmhalten, ohne dass sie platzen (z.B. Weißwürste bei 75°C).
• f) Joghurtherstellung.
• g) Niedrigtemperaturgaren.
• h) Dünsten bei vorgegebener Temperatur.
• i) Frittieren.

The system described above allows a very accurate temperature measurement of the food (measuring the temperature of the product), especially in a temperature range around 65 ° C or lower, where conventional IR temperature measurements of an outside of the cookware no longer work reliably. The exact temperature measurement and thus also temperature control makes it possible - for example also in conventional resistance heating conductors as cookware heating means - for example the following cooking programs or preparation programs:

• a) Rice cooking: Here, a temperature jump, which occurs when the water used for rice cooking is evaporated, can be detected with high accuracy. Subsequently, it is possible to switch from a cooking mode to a keep-warm mode.
• b) Steak program: Here the exact temperature measurement can be used to sear meat first, and then to cook at a lower temperature.
• c) Cooking side dishes such as noodles, potatoes or vegetables at constant temperature or with a steam cooking attachment.
• d) let dough go.
• e) heat sausages and keep them warm without bursting (eg white sausages at 75 ° C).
• f) yoghurt production.
• g) low temperature cooking.
• h) steaming at a given temperature.
• i) frying.

It is an embodiment that preparation or cooking programs are executable or feasible, in which at least one desired temperature of the food to be 80 ° C, especially 70 ° C, especially 60 ° C, especially 50 ° C, especially 40 ° C, in particular 30 ° C, is. In particular, a maximum target (food) temperature 80 ° C, in particular 70 ° C, in particular 60 ° C, in particular 50 ° C, in particular 40 ° C, in particular 30 ° C, amount. In particular, so are also cooking or cooking programs feasible, in which a minimum target (food) temperature below 80 ° C, especially 70 ° C, especially 60 ° C, especially 50 ° C, especially 40 ° C, especially 30 ° C. , lies. Such a "low temperature" control is made possible by the high accuracy of the temperature measurement even at low temperatures, as e.g. by an IR measurement on an outside of the cookware is not possible. In particular, a cooking temperature of 65 ° C or even less can still be determined with sufficient accuracy and set as a target (food) temperature.

It is a development that the system is adapted to operate at least one cookware without temperature control, e.g. with a heating power set manually, for example via cooking levels.

It is still a further development that the system has a "Guided Cooking" function in which the cooking appliance - e.g. on the basis of stored cooking programs - can automatically set cooking temperatures and cooking times, heat, switch off and require after addition of necessary ingredients or after performing certain operations by the user.

It is also a development that the system is set up to perform at least one automatic cooking step. It can be carried out after the definition of cooking time and cooking temperature, a cooking cycle with automatic temperature control and shutdown after the set cooking time.

It is further a development that the system is adapted to receive recipes, e.g. for Guided Cooking from an external unit to receive and save. The external unit may be a smartphone, a computer, a laptop, a smart watch, and so on.

It is also a further development that the cooking appliance by means of an external device such as a smartphone, a computer, a laptop, a smart watch, etc. is monitored, in particular also controllable, is.

It is also a development that the cooking appliance can be connected to a domestic appliance network, for example, the so-called. "Home Connect". The cooking appliance can be monitored and, if necessary, controlled via the domestic appliance network.

The object is also achieved by a cookware as described above and / or by a cooking appliance as described above.

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 an embodiment which will be described in detail in conjunction with the drawings.

1 shows a sketch of a system 1 . 2 with a cooking device in the form of a cooker 1 and with an attached cookware in the form of an electrically operable, intelligent pot 2 , The stove 1 has a hob on the top 3 on, which comprises a plurality of cooking zones (not shown), wherein on the hobs a respective cookware is placed.

The pot 2 has a receiving space on the upper side open 4 for food or food. In the area of a floor 2a of the recording room 4 there is a temperature sensor 5 that with a circuit in the form of a pot electronics 6 electrically connected (indicated by dashed lines). The temperature sensor 5 feels indirectly above the ground 2a a temperature of in the receiving space 4 from the food. The pot electronics 6 is configured to at least one temperature signal of the temperature sensor 5 record and process, eg to digitize, format and / or calculate derived data. The processed temperature signal is from the pot electronics 6 to a transmission device in the form of a wireless transmitter 7 passed on. The transmitter 7 can in the pot electronics 6 be integrated. The pot electronics 6 and the transmitter 7 are here in one handle 2 B of the pot 2 integrated, which is particularly advantageous for protection against thermal overload. The pot electronics 6 can be implemented in Surface Mount Technology (SMT) and sealed as a module.

The pot electronics 6 and the transmitter 7 be by means of an electrical supply device in the form of a ("pot" -) coil 8th powered. The sink 8th can be connected to a rectifier, etc. (not shown) to produce a DC supply voltage. The sink 8th at the same time serves as antenna for the transmitter 7 , Also regarding the coil 8th it is advantageous if it is not arranged so that it is shielded by the bottom of the pot. This is the coil 8th formed here as a lateral winding, for example as a laterally around the bottom of the pot 2a wrapped around winding. The sink 8th may be shed for their protection.

The stove 1 also has a ("hearth") coil on each of the hobs 9 on, the at essay of the pot 2 with its coil 8th transformer (ie, similar to two transformer halves) can couple. The stove 1 has a control panel for its operation 10 on. A user can use the keypad 10 for a pot's operation 2 set input parameters - eg select a treatment or cooking program, select a desired cooking temperature, etc. - and activate the associated hotplate. The hotplate is then powered by a circuit in the form of a stove electronics 11 controlled, via a power control 12 which the coil 9 energized with alternating current.

Through this energization the coil generates 9 an alternating magnetic field at the location of the coil 8th , In the coil 8th As a result, an alternating voltage is generated which - if necessary rectified and smoothed - for the operation of the pot electronics 6 and the sender 7 is used. The pot electronics 9 can then be from the temperature sensor 5 process received temperature signals, and the transmitter 7 can process the processed temperature signals to the coil 8th impress. The sink 8th thereby sends the processed temperature signals wirelessly as temperature data to the coil 9 , which therefore also (like the coil 8th ) serves as a power coil and data transmission coil. This temperature data can be from the stove electronics 11 be processed so that the stove electronics 11 the actual cooking temperature is present. The stove electronics 11 uses the actual cooking temperature to the cooking temperature in the pot 2 to regulate to a set or specified by a cooking program cooking temperature.

Each of the cooking zones also has a cookware heating means, here a heat-transmitting heating element 13 like an electrically operated resistance heating, on to heat the food. Thus, at the hob also a conventional pot, pan, etc. can be operated. In particular, the conventional heating element 13 be operated in a conventional power mode when the stove 1 recognizes that although there is a cookware at the associated hotplate, this is not a transformer-operated cookware.

To detect if a smart pot 2 is present at a cooking place, the stove, the individual cooking zones on the associated hearth coils 9 briefly with energy for the stove electronics 6 supply. This can be the stove electronics 11 recognize on which hotplate a suitable pot 2 stands, because the pot 2 delivers to the stove 1 a temperature signal as soon as it is supplied with energy. Of course, the present invention is not limited to the embodiment shown.

Generally, "on", "an", etc. may be taken to mean a singular or a plurality, in particular in the sense of "at least one" or "one or more" etc., unless this is explicitly excluded, e.g. by the expression "exactly one", etc.

Also, a number may include exactly the specified number as well as a usual tolerance range, as long as this is not explicitly excluded.
