Definitions

  • 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 14 and a cooking utensil for carrying out such a method according to claim 15.
  • a cooking process can also be supported, for example, by the hob and/or by a mobile device, in that the cooking process is tracked there, presented to the user and the next actions in the recipe process are displayed or corresponding instructions are given to the user.
  • the hobs should visually disappear further and further from the kitchen. This also includes making the hob controls increasingly inconspicuous or making them disappear completely. This may result in relocating the cooktop controls to the cookware. Therefore, it may be necessary or at least desirable to be able to exchange information between the cookware and the hob. This may include the transmission of instructions as well as metrics.
  • the method can be implemented in accordance with standards while avoiding a long-distance effect by using an inductive power on the part of the hotplate as an emitted signal of the pairing, the reception of which by the cookware only triggers the emission of the second signal. Because the inductive power of the hotplate can only be absorbed by the cookware when there is direct contact or with a maximum distance of approx. 5 cm between the hotplate or its coil and the cookware, the pairing can only be successful if this Framework conditions are met. Otherwise, pairing will not take place and the automated cooking process will not start.
  • the communicating electronic cooking item or items have a switching device, which can be a mechanical, capacitive or electromechanical button and can be arranged on the handle of the communicating electronic cooking device. By pressing this switch-on device, electrical power is supplied to the signal processing unit. As soon as it is supplied with electrical power, 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 switching device which can be a mechanical, capacitive or electromechanical button and can be arranged on the handle of the communicating electronic cooking device.
  • EP 3 416 457 A1 As well as the EP 3 111 144 B1 is that the use of a mobile device or its app can be dispensed with in order to carry out a pairing between a hotplate on the hob and the cookware and, if necessary, to start an automated cooking process.
  • the disadvantage is that for a pairing or a pairing between a hotplate of the hob and the cookware, a step of actuating the actuating element of the cookware by a user and thus an action by the user on the cookware is required, which is perceived as cumbersome by the user can.
  • 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 the pairing. Finally, a signal is sent out one after the other by the cookware, a hotplate or all hotplates are operated by the hob in response to receiving the signal and a second signal is sent in response to a detected operation of a hotplate of the cookware, which in turn is sent by the hob is to be received. Only then has a pairing been successfully completed. This can lead to a time delay in pairing, which can be perceived as annoying by the user.
  • the invention therefore presents the problem of providing a method for operating a cooking system of the type described above, so that a pairing between a hotplate of a hob and a cookware or cooking utensil is easier, faster and/or more comfortable for the user than previously known. A long-distance effect should be ruled out. At least an alternative to known such methods of pairing between a hotplate of a hob and a cookware or cooking utensil should be created.
  • a cooking utensil or a cookware such as a pot, a pan, a wok and the like can be recognized as being on a specific hotplate of the hob by, on the one hand, one of the cooking utensils
  • Information specific to the cooking utensil is sent out as cooking utensil parameters and received by the hob.
  • the cooking utensil can have a corresponding transmission unit and, if necessary, a further control unit.
  • the cooking utensil can also provide an electrical supply for this using a battery, an accumulator, a capacitor or even using energy harvesting.
  • the transmission is preferably carried out wirelessly, such as via Bluetooth.
  • the hob has a, preferably wireless, receiving unit and also a control unit in order to receive the information about the cooking utensil parameter from the cooking utensil, if necessary to temporarily store it and process it.
  • the hob can preferably be supplied with electricity using a cable.
  • the data transfer from the cooking utensils to the hob can take place directly or indirectly, for example via a home WLAN, a mobile phone network and the like.
  • the hob checks the hotplate and preferably all free, i.e. unpaired or unpaired, hotplates to determine whether there is a cooking utensil on the hotplate or on one of the free hotplates the same value of the cooking utensil parameter that is received from the cooking utensil can be recognized.
  • cooking utensil being sent is on this hotplate on the hob. Accordingly, cooking utensils and cooking areas can be paired and the cooking utensils can be operated there. This can therefore be done comparatively easily, quickly and in particular in comparatively few steps, some of which can take place in parallel to one another, which can correspondingly accelerate the pairing process.
  • the hob or its control unit concludes that the cooking utensil is not on the hotplate or . is not on any hotplates on the hob. This can be the case if the cooking utensil sends its value of the cooking utensil parameter to the hob, but is not on the hob or on the entire hob, so that no value of the cooking utensil parameter of the cooking utensil on the hob is sent from the hob or can be determined on any of its cooking areas. This also applies for those of several hotplates on the hob on which the cooking utensils are not located.
  • the hob has one or more hotplates, in particular 2, 3, 4, 5, 6 or more hotplates.
  • the value of the cooking utensil parameter of the cooking utensil is determined by the hob for several cooking zones, preferably simultaneously. Accordingly, several hotplates of the hob can be checked as described above to see whether the corresponding cooking utensils with the matching cooking utensil parameters are located there or not. Doing this for several hotplates in parallel can speed up the process.
  • the value of the cooking utensil parameter of the cooking utensil is determined by the hob for the cooking area, preferably in a standby mode of the hob, continuously repeating, preferably at time intervals, until there is a match.
  • the determination can thus take place continuously, so that the determination does not have to be started additionally by the user, which could represent additional effort for the user.
  • the determination can be carried out continuously or periodically at intervals of a few seconds.
  • the determination by the hob can only be made continuously for this purpose if the hob is in a standby mode, i.e. is switched on or activated and is waiting to carry out a cooking process.
  • the value of the cooking utensil parameter of the cooking utensil is determined by the hob by means of inductive coupling.
  • an inductive coupling to the cooking utensil or its base can be established on the part of the hotplate of an inductive hob or on the part of a hotplate of another hob equipped with an inductive sensor, and from this inductive coupling a parameter characteristic of the cooking utensil can be determined, which also is known to the cooking utensil itself and can be emitted accordingly by the cooking utensil. This can be one way of implementing it.
  • the cooking utensil parameter of the cooking utensil represents the base dimension of the cooking utensil.
  • the bottom dimension of the cooking utensil which can be determined in particular by means of inductive coupling as described above, represents the characteristic parameter for the cooking utensil. This can represent one possible implementation.
  • the value of the cooking utensil parameter of the cooking utensil is sent from the cooking utensil to the hob continuously and repeatedly, preferably at time intervals, until there is a match.
  • pairing can take place even if the cooking utensil is already activated or starts transmitting before the hob is ready to receive. Doing this continuously but at different times can save effort and energy, as already described above.
  • the value of the cooking utensil parameter of the cooking utensil is sent from the cooking utensil to the hob in response to activation of the cooking utensil.
  • the cooking utensil can be activated by an additional action by the user, such as the actuation of a control or activation element of the cooking utensil, for example by pressing or touching a button or the like.
  • activation can also take place through a movement or operation of the cooking utensil, which can be detected by sensors from the hob or the cooking utensil itself.
  • This can be, for example, a movement of the cooking utensil, which can be detected by a motion sensor of the cooking utensil itself or by a motion sensor or optical sensor of the hob.
  • activating can trigger or cause the following procedural steps.
  • the cooking utensil is activated by a movement of the cooking utensil that is detected by sensors. As previously described, this can be done automatically and relieve the user of an additional step of activation, such as by pressing or touching a button or the like. This can also speed up activation.
  • the value of the cooking utensil parameter of the cooking utensil is sent from the cooking utensil to the hob for several cooking utensils.
  • the method according to the invention as described above, can also be used on several cooking utensils in order to pair them with the hob. Accordingly, the properties and advantages described above can be implemented and used.
  • several cooking utensils with the same values of the cooking utensil parameter on the hob can be distinguished from one another by the time offset of sending, receiving, determining and comparing.
  • the method according to the invention is carried out one after the other for several cooking utensils as described above, so that only one cooking utensil is paired with the hob at the same time.
  • cooking utensils with the same cooking utensil parameter values can also be clearly assigned to a cooking area because the cooking utensils cannot be confused with one another despite their identical cooking utensil parameter values.
  • several cooking utensils with the same values of the cooking utensil parameter can be distinguished from one another by an input from a user on the hob. If it happens that several cooking utensils with the same cooking utensil parameter values are to be paired at the same time, the comparison cannot lead to a clear result. In this case, user intervention may be necessary in order to clearly assign the individual cooking utensils to the cooking zones of the hob.
  • this can remain an exceptional case, so this effort for the user can usually be avoided as described above.
  • Information can thus be output to the user that a match between the values of the cooking utensil parameters of the cooking utensil was recognized by the hob or its control unit.
  • Such information can be output visually, acoustically, haptically and/or through other communication, for example via a mobile device. This allows the user to be informed about a successful pairing.
  • the invention also relates to a hob for carrying out a method as described above.
  • a hob can be provided to enable the previously described method according to the invention to be carried out with its properties and advantages.
  • the invention also relates to cooking utensils for carrying out a method as described above.
  • cooking utensils can be provided to...
  • a longitudinal direction X extends, which can also be referred to as depth X or length X.
  • a transverse direction Y extends perpendicular to the longitudinal direction X, which can also be referred to as width Y.
  • a vertical direction (not shown), which can also be referred to as height, extends perpendicular to both the longitudinal direction X and the transverse direction 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 utensils 2.
  • the hob 1 is an inductive hob 1 and has one or more hotplates 10, in particular 2, 3, 4, 5, 6 or more hotplates 10.
  • the hob 1 has a total of five hotplates 10, which are in one First to fifth hotplates 10a, 10b, 10c, 10d, 10e can be distinguished.
  • an operating/display element 11 is provided, which has a confirmation element 12.
  • a first cooking utensil 2a in the form of a cooking pot 2a is operated on the second hotplate 10b and a second cooking utensil 2b in the form of a pan 2b is operated on the fourth hotplate 10d.
  • Each cooking utensil 2 in turn has an actuating element 20 on the handle or handle.
  • the hob 1 is in a ready or stand-by mode, into which the hob 1 was placed by the user by operating the control/display element 11. Now the hob 1 is ready to be operated, ie to receive input from the user, for example to select the power level of a hob. Furthermore, the hob 1 now simultaneously detects the presence of a cooking utensil 2 on the respective hob 10 for all of its five hotplates 10 at intervals of, for example, 10 seconds.
  • a value of a cooking utensil parameter of the cooking pot 2a is wirelessly sent from the cooking pot 2a to the hob 1.
  • the cooking utensil parameter of the cooking pot 2a represents the base dimension of the cooking pot 2a.
  • the transmitted value of the cooking utensil parameter of the cooking pot 2a is received by the hob 1 by means of a wireless receiver 300 and temporarily stored there. The repeated detection of the presence of a cooking utensil 2 on the respective hotplate 10 of the hob 1 continues to be carried out, although so far without results.
  • the hob 1 cannot determine whether the activated cooking pot 2a or another, in particular non-sending, cooking utensil 2 has been placed on the second hotplate 2b of the hob 2.
  • the hob 1 now determines 400 a value of the cooking utensil parameter of the cooking utensil 2 for that hotplate 10 for which the presence of any cooking utensil 2 has been detected.
  • This specific value of the cooking utensil parameter is now in a step of comparing 500 compared to the received value of the cooking utensil parameters of the cooking pot 2a compared.
  • the cooking pot 2a is the cooking utensil 2 recognized as being present.
  • the cooking pot 2a can be operated 600 by the hob 1 on the second hotplate 10, which represents a pairing of the cooking utensil 2 to the hotplate 10.
  • the user can now be informed 800 about the correspondence of the values of the cooking utensil parameters of the cooking utensil 2 in order to point out to the user that the cooking pot 2a can be used on the second hotplate 10b of the hob 1.
  • the cooking utensil 2 is not operated 700 by the hob 1 on the hotplate 10, i.e. no pairing takes place.
  • pan 2b as a second cooking utensil 2b, which can be paired in this way with the fourth hotplate 10d of the hob 1.
  • Both cooking utensils 2 can be distinguished on the one hand in that they have different base dimensions and therefore different cooking utensil parameters. Accordingly, both cooking utensils 2 can also be paired with the hob 1 or its cooking zones 10 at the same time or parallel to one another, without being confused.
  • one of the cooking utensils 2 can be caused to send out a wireless signal by means of its actuating element 20, which can also be received by the hob 1 and assigned to the corresponding cooking area 10.
