Definitions

  • the invention relates to a method for operating a cooking system, a hob for carrying out such a method and a cooking utensil for carrying out such a method.
  • a cooking process can also be supported, for example, by the hob and/or a mobile device, by tracking the cooking process, presenting it to the user, showing the next steps in the recipe sequence and giving the user appropriate instructions.
  • the hobs are to disappear visually from the kitchen more and more. This also includes making the controls on the hobs more and more inconspicuous or making them disappear completely. This may lead to the hob controls being moved 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 may include the transmission of instructions as well as measurements.
  • the user's single actuation of the cookware's operating element triggers a pairing between the hob or its hotplate and the cookware, which leads to a connection between the hotplate and the cookware.
  • the user's single actuation of the cookware's operating element triggers a signal being sent from the hotplate back to the cookware, which triggers a reaction from the cookware, which leads to a successful pairing of the cookware and the hob or hotplate.
  • This successful pairing can be used by the hob as a reason be used, for example, to carry out an automated cooking process for this cooking area.
  • This automated cooking process can be triggered by the user by pressing the operating element of the cookware once.
  • the process can be implemented in accordance with standards and without remote effects by using an inductive power as the transmitted pairing signal from the cooking area, the reception of which by the cookware triggers the transmission of the second signal. Because the inductive power of the cooking area can only be received by the cookware when there is direct contact or at a maximum distance of approx. 5 cm between the cooking area or its coil and the cookware, pairing can only be successful if this framework is met. Otherwise, no pairing takes place and the automated cooking or cooking process is not started.
  • the communicating electronic cooking item(s) have a switch-on device, which can be a mechanical, capacitive or electromechanical button and can be arranged on the handle of the communicating electronic cooking appliance. By pressing this switch-on device, electrical current is supplied to the signal processing unit. As soon as it is supplied with electrical current, the signal processing unit generates an activation signal. This activation signal is generated ad hoc by the signal processing unit and then sent by the communication module.
  • a switch-on device can be a mechanical, capacitive or electromechanical button and can be arranged on the handle of the communicating electronic cooking appliance.
  • a disadvantage is that pairing between a cooking zone on the hob and the cookware still requires a step of operating the cookware's operating element by a user and thus an action by the user on the cookware, which the user may find cumbersome.
  • Another disadvantage is that several steps are required on the part of the cookware and the hob, which must be carried out one after the other and alternately in order to achieve pairing. Finally, a signal is sent out one after the other from the cookware, one or all of the hobs is operated by the hob in response to receiving the signal, and a second signal is sent in response to a detected operation of a hob on the cookware, which in turn is sent out by the hob. is received. Only then is pairing successful. This can lead to a delay in pairing, which the user may find annoying.
  • the EP 3 273 831 B1 describes a device for managing the cooking of foodstuffs, intended to be removably arranged on a cooking vessel cooperating with a hotplate, the cooking management device being arranged to emit signals intended either to control the hotplate or to prompt the user to act on the hotplate and/or the foodstuffs being cooked, characterized in that the cooking management device comprises a system for detecting the type and/or size of the cooking vessel on which it is arranged, the detection system acting on the cooking management device to adapt the signals emitted as a function of the type and/or size of the cooking vessel detected.
  • the EN 10 2011 085 524 A4 describes a cooking device with at least two cooking devices, at least two sensor devices that can be attached to the respective cooking device for detecting at least one parameter influencing a cooking process in the respective cooking device, wherein the sensor devices communicate wirelessly with a base station and wherein the base station is designed to monitor and manage at least two cooking devices, characterized in that at least two different foods to be cooked can be selected at the base station, which are to be cooked in the at least two cooking devices, wherein the sensor devices each have an RFID chip or a thermoelectric generator and wherein the thermoelectric generator uses the temperature difference between the internal temperature in the cooking device and the ambient temperature to generate energy.
  • the invention therefore addresses the problem of providing a method for operating a cooking system of the type described at the outset, so that pairing or a connection between a hotplate of a hob and a piece of cookware or cooking utensils can be carried out more easily, quickly and/or conveniently for the user than previously known. In this case, a remote effect should be excluded.
  • an alternative to known methods of pairing or a connection between a hotplate of a hob and a piece of cookware or cooking utensils should be created.
  • the attempt to establish wireless communication between a cooking utensil in the form of a sensor or system cooking utensil with a corresponding hob or one of its cooking areas is deliberately attempted with a wireless communication transmission power that reduces the range within which this attempt can be successful. Accordingly, the range or distance between the cooking utensil and the hob or cooking area can be kept sufficiently small so that successful pairing can only take place in the immediate vicinity. This ensures that long-distance effects can be excluded.
  • the first, lower transmission power is sufficiently low to only be received by the hob if the cooking utensil is arranged sufficiently close to the hob, preferably to the cooking area of the hob, to exclude a long-distance effect.
  • the second, higher transmission power is sufficiently high to enable a higher data transmission than with the first, lower transmission power.
  • the cooking utensil can be activated by an additional action by the user, such as activating a control or activation element of the cooking utensil, for example by pressing or touching a button or the like. This can create the prerequisite for carrying out the following steps and functions described above. Otherwise, these can be prevented and energy for operating the cooking utensil can be saved accordingly.
  • the cooking utensil can also be transferred from a rest, ready or standby mode to an active operation. In each case, this takes place as a separate step and independently of the query step, etc.
  • the request is made in response to an activation of the cooking utensil.
  • the activation can be carried out by a corresponding action of the user, as described above, or alternatively by a movement or Operation of the cooking utensil can be carried out in a way that can be detected by the cooking utensil itself. This can be, for example, a movement of the cooking utensil, which can be detected by a motion sensor on the cooking utensil itself.
  • activation can trigger or initiate the following process steps, so that no additional action by the user is required. This can speed up the process or relieve the user of another step.
  • the cooking utensil is activated by a movement of the cooking utensil detected by a sensor. This can take place automatically as already described and relieves the user of an additional activation step, such as by pressing or touching a button or the like. This can speed up the process and/or relieve the user accordingly.
  • the request for wireless pairing includes a user selecting a function and/or a functional parameter of the cooking utensil.
  • a user selecting a function and/or a functional parameter of the cooking utensil can be seen as an incentive to carry out the pairing as described above and thus also to activate the selected function or to carry out the corresponding parameterization, so that a corresponding further step can be saved. This can speed up the process and/or relieve the user accordingly.
  • the second, higher or Using normal transmission power can make it possible to exploit the possibilities of data transmission of the sensor values as well as possible or even completely, which can improve the quality of the data transmission and thus of the control or regulation.
  • the sensor value is a temperature value, preferably a food temperature value. This can enable the corresponding implementation of a cooking process.
  • the invention also relates to a hob for carrying out a method as described above.
  • a hob can be provided to enable the above-described method according to the invention to be carried out with its properties and advantages.
  • the invention also relates to a cooking utensil for carrying out a method as described above.
  • a cooking utensil can be provided to enable the above-described method according to the invention to be carried out with its properties and advantages.
  • the integration of cooking zone-independent assistance functions in the form of "intelligent” cooking utensils is increasingly being planned.
  • the intelligent cooking utensils must be equipped with suitable sensors, electronics, UI/UX (user interface), measuring electronics and an energy storage device and connected wirelessly, for example with Bluetooth (BT).
  • BT Bluetooth
  • the "smart cookware” can also be referred to as sensor cooking utensils or system cooking utensils.
  • the "smart cookware" can be connected directly to the hob via BT. Assistance levels can be selected via the UI/UX on the cookware. Temperatures and/or power levels are also conceivable.
  • the disadvantage is that reducing the transmission power can also lead to a significant reduction in the data rate of the interface.
  • a solution is therefore being sought in which the transmission line is set dynamically.
  • the idea is that all safety-critical requirements from the "smart cookware" such as selecting the assistance or power levels, switching on, etc. are requested with a comparatively low transmission line in order to ensure that remote operation can be ruled out or that the "smart cookware" is located in the vicinity of the hob.
  • the transmission power can easily be increased after selecting the assistance in order to achieve the maximum data rate on the interface. This applies to all actions and situations that are not critical from the point of view of the system safety analysis.
  • the above figures are viewed in Cartesian coordinates.
  • a longitudinal direction X which can also be referred to as depth X or length X.
  • a transverse direction Y Perpendicular to the longitudinal direction X there is a transverse direction Y, which can also be referred to as width Y.
  • a vertical direction Z Perpendicular to both the longitudinal direction X and the transverse direction Y there is a vertical direction Z, which can also be referred to as height Z and corresponds to the direction of gravity.
  • the longitudinal direction X and the transverse direction Y together form the horizontal X, Y, which can also be referred to as the horizontal plane X, Y.
  • FIG. 1 shows a schematic representation of a cooking system 1, 2 for carrying out a method according to the invention from above.
  • the cooking system 1, 2 consists of a hob 1 with several cooking dishes 2.
  • the hob 1 is an inductive hob 1 with several cooking zones 10 in the form of a first cooking zone 10a and a second cooking zone 10b. Furthermore, an operating/display element 11 and a wireless transmitting/receiving unit 12 are provided.
  • a first cooking utensil 2a in the form of a cooking pot 2a is operated on the first cooking zone 10a and a second cooking utensil 2b in the form of a pan 2b is operated on the second cooking zone 10b.
  • Each cooking utensil 2 has a control/display element 20 on the handle or on the handle as well as a transmitting/receiving unit 21.
  • the wireless communication between the wireless transmitting/receiving unit 12 of the inductive hob 1 and the wireless transmitting/receiving units 21 of the cooking utensils 2 takes place via Bluetooth (BT).
  • BT Bluetooth
  • the hob 1 is in a stand-by mode, into which the hob 1 was placed by the user by operating the control/display element 11.
  • the hob 1 is now ready to be operated, ie to receive inputs from the user, eg for selecting the power level of a hotplate 10.
  • a request 200 is made for wireless pairing of the cooking utensil 2 with the hob 1 or with the specific first hotplate 10a of the hob 10 with a first, lower transmission power.
  • a pairing request is specifically sent 230 with the first, lower transmission power from the wireless transmission/reception unit 21 of the cooking utensil 2 to the wireless transmission/reception unit 12 of the hob 1.
  • the first, lower transmission power is sufficiently low to only be received by the hob 1 if the cooking utensil 2 is arranged sufficiently close to the hob 1 or to the first hotplate 10a of the hob 1 to rule out a remote effect.
  • the pairing request of the wireless transmitting/receiving unit 21 of the cooking utensil 2 is received 260 by the wireless transmitting/receiving unit 12 of the hob 1, which leads to the wireless pairing 300 of the cooking utensil 2 with the hob 1 or with its first cooking point 10a.
  • a pairing confirmation is now sent 330 with the first, lower transmission power from the wireless transmitting/receiving unit 12 of the hob 1 to the transmitting/receiving unit 21 of the cooking utensil 2.
  • the cooking utensil 2 is now operated 400 on the hob 1 or on its first cooking zone 10a with a second, higher transmission power. Thanks to the second, higher transmission power, the possibilities of higher data transmission can be used than with the first, lower transmission power of the pairing.
  • a sensor value is transmitted 430 with the second, higher transmission power from the wireless transmitting/receiving unit 21 of the cooking utensil 2 to the transmitting/receiving unit 12 of the hob 1.
  • the cooking point 10 of the hob 1 is operated 470 depending on the received sensor value of the cooking utensil 2. This can enable a temperature-controlled or temperature-regulated cooking operation or cooking process with a correspondingly high quality of the wireless data transmission.
