Definitions

  • the invention relates to a cooking system.
  • 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 also supposed to disappear visually from the kitchen more and more. This also includes making the hob controls more and more inconspicuous or making them disappear completely. This can lead to the hob controls and display elements being moved to the cookware. It can 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 and measurements.
  • a second operating mode for induction hobs is now known: areas of the hob have a fixed power level, which is set at the factory or can be changed by the user in the menu settings. If a cooking utensil is placed or pushed onto an area of the hob and is recognized by the hob, this area of the hob will be operated at the assigned power level. This can save the user from having to set the power level and activate the hotplate. This can increase the comfort of use and save time.
  • the EP 3 509 394 A1 describes a method for operating a hob which has at least one user interface and which, in at least one operating state in which only a heating power of a maximum of one heating power limit is available for heating a cooking utensil with at least one existing heating type, which is smaller than a heating power that can be selected for the existing heating type in at least one other operating state, prevents the heating power limit from being exceeded.
  • Exceeding the heating power limit is prevented by adapting the user interface depending on the existing heating type.
  • the input selection of the user interface can thus be limited, for example, by hiding heating powers that would exceed the heating power limit.
  • the invention therefore addresses the problem of improving the possibilities for a user to set or change a cooking parameter of a hob. This should be possible in particular during the ongoing cooking process. This should in particular improve or ensure the safety of the hob or cooking process. This should be possible in particular for induction hobs, especially for surface induction hobs. In any case, this should be possible in a way that is as simple, cost-effective, space-saving and/or intuitive as possible. At the very least, an alternative to the known possibilities should be created.
  • the invention thus relates to a cooking system with a hob with a plurality of cooking zones, wherein at least one first cooking zone is assigned a first predetermined value of a cooking parameter and at least one second cooking zone is assigned a second predetermined value of the cooking parameter, with a cooking utensil detection device which is designed and configured to determine the position of a cooking utensil on the hob, wherein the cooking system, preferably a control unit of the cooking system, is designed and configured to operate the cooking zone automatically with the respective predetermined value of the cooking parameter if the cooking utensil is detected on the cooking zone, and with an operating element, preferably of the hob, which is designed and configured so that a user can change at least one of the two predetermined values of the cooking parameter, preferably during operation of the cooking point, wherein the cooking system, preferably the control unit of the cooking system, is designed and configured to allow the value of the cooking parameter of the first cooking point to be changed only as a function of the value of the cooking parameter of the second cooking point.
  • the cooking zones can be formed by positions or areas of the hob that are specifically designed as cooking zones, for example by individual gas burners, electric cooking zones or induction coils.
  • the cooking zones can also be formed flexibly by several induction coils of a full-surface cooking zone, which can be operated together if required to form cooking zones.
  • the cooking utensil can in particular be a pot, a pan or the like. Such cooking utensils can be referred to as system cooking utensils.
  • the cooking utensil detection can be carried out optically, for example by means of at least one optical detection unit, which can preferably be arranged above the hob, for example on or in an extractor hood, or behind the hob and can be aligned with the hob.
  • this can also be done additionally or alternatively by means of an interaction between the hob and the cooking utensil, for example by detecting the presence or absence of a cooking utensil by means of an existing or missing inductive coupling, which the hob can attempt to establish, in particular for a short time only for this purpose.
  • This can also be done by the cooking utensil sending out a signal for this purpose, which can be received and recognized by the hob or not.
  • the respective cooking zone can be operated directly with this value of the cooking parameter when the user places or pushes the cooking utensil onto the corresponding cooking zone and this is recognized by the cooking system.
  • a cooking parameter such as a power, a power level or a temperature or food temperature
  • the user can change the value of the cooking parameter of at least one of the two cooking zones or both cooking zones by means of a control element, which can be part of the cooking zone or a separate control element, for example in the form of a mobile device such as a smartphone of the user.
  • a control element which can be part of the cooking zone or a separate control element, for example in the form of a mobile device such as a smartphone of the user.
  • This can enable the user to set the value of the cooking parameter of at least one cooking zone according to his or her preferences. This in particular during the ongoing cooking process can accelerate the use of the changed setting or enable it directly.
  • the cooking system and in particular its control unit, in particular the hob or the mobile device can check the admissibility of the user's input or change of the cooking parameter before this is implemented or saved if necessary.
  • the value of the cooking parameter to be changed for one cooking zone can be considered in relation to the current value of the cooking parameter for the other cooking zone, as will be described in more detail below. This makes it possible according to the invention to ensure that the values of the cooking parameters for both cooking zones remain coordinated with one another despite the user changing the cooking parameter.
  • a sensible parameterization of the two cooking surfaces can be maintained or ensured in order to be able to operate the cooking utensils directly on both cooking surfaces as described above, without having to make additional settings for the cooking parameter values on one cooking surface.
  • a weaker cooking process with a lower cooking parameter value of the second cooking surface can take place in the depth behind the user, away from the user. This can be done in a comparable transverse direction, for example from left to right.
  • At least a third cooking zone can be provided, which can have an even lower cooking parameter value, so that the second cooking zone can have an average cooking parameter value.
  • the third cooking zone can be used, for example, to keep food warm in the cooking utensils and can be arranged further back or right at the back of the hob, since in this case the user will hardly need to intervene in the cooking process, such as stirring or turning the food.
  • the cooking system preferably the control unit of the cooking system, is designed and configured to allow only a value that is equal to or lower than the value of the cooking parameter of the first cooking zone as the changed value of the cooking parameter of the second cooking zone. This can ensure that the value of the cooking parameter of the second cooking zone exceeds the value of the cooking parameter of the first cooking zone cannot be exceeded. This means that the first cooking zone can always remain the cooking zone with the highest cooking parameter value and can only be expanded by the second cooking zone. This means that even if the cooking parameter value of the second cooking zone is changed, the user can still use the hob as usual and thus make it more intuitive to use.
  • the cooking system preferably the control unit of the cooking system, is designed and configured to only allow a value that is equal to or greater than the value of the cooking parameter of the second cooking point as the changed value of the cooking parameter of the first cooking point. This can enable the use described above also with regard to the first cooking point.
  • the cooking system preferably the control unit of the cooking system, is designed and configured to allow only predetermined higher values as values of the cooking parameters of the first cooking zone, preferably to allow selection, than for the second cooking zone.
  • the restricted selection can be made in particular by a correspondingly restricted selection of a display of the control element. This can also be done by dimly displayed or grayed out information that is not available for selection.
  • the cooking system preferably the control unit of the cooking system, is designed and configured to give the user a notice if the change in the value of the cooking parameter is not permitted. This can make it easier for the user to select permissible values, as impermissible selections can be better recognized or perceived by the user. Such a notice can be provided visually, acoustically and/or haptically.
  • the cooking system preferably the control unit of the cooking system, is designed and configured to automatically increase the value of the cooking parameter of the first cooking zone to the value of the cooking parameter of the second cooking zone if the changed value of the cooking parameter of the second cooking zone is greater than the value of the cooking parameter of the first cooking zone.
  • a supposedly impermissible selection by the user can thus be automatically "corrected" by the cooking system or its control unit in that the value of the cooking parameter of the first cooking zone can also be increased and thus not be less than the value of the cooking parameter of the second cooking zone.
  • the cooking system preferably the control unit of the cooking system, is designed and arranged to determine the value of the The cooking parameter of the second cooking zone is automatically reduced to the value of the cooking parameter of the first cooking zone if the changed value of the cooking parameter of the first cooking zone is lower than the value of the cooking parameter of the second cooking zone. Accordingly, the aspect described above can also be transferred to the other cooking zone and applied there in a comparable manner.
  • the cooking system preferably the control unit of the cooking system, is designed and configured to automatically change the value of the cooking parameter of the second cooking zone in a predetermined relationship, preferably to half, to the value of the cooking parameter of the first cooking zone, or vice versa. This allows the previous or desired relationship between the values of the cooking parameters of both cooking zones to be automatically maintained.
  • the cooking system preferably the control unit of the cooking system, is designed and configured to automatically change the value of the cooking parameter to the closest value of the cooking parameter if the change in the value of the cooking parameter is not permitted by the user.
  • This can also represent a possibility of automatically "correcting" a supposedly impermissible selection by the user by the cooking system or its control unit and implementing the direction of the change by the user as far as possible within the scope of what is permitted.
  • the cooking parameter is the power level of at least one cooking zone or the power of at least one cooking zone or the temperature at at least one cooking zone.
  • the use of the temperature of the cooking zones can in particular be the temperature of the food to be cooked, in particular in order to be able to carry out a temperature-controlled cooking process.
  • the power level of a cooking zone is preferably a setting that can be set by the user on a control element.
  • the power of a cooking zone is in particular the heating power of the cooking zone, for example in the form of a surface power or an electrical power.
  • the cooking utensil has at least one sensor for detecting a cooking temperature as a cooking parameter and at least one transmitter for transmitting the detected cooking parameter, and the hob has a receiver for receiving the detected cooking parameter from the cooking utensil. This can enable the implementation of a temperature-controlled cooking process.
  • the cooking utensil detection device is designed to optically determine the position of a cooking utensil on the hob. This can enable the concrete implementation, as already described above.
  • the cooking utensil detection system is designed to determine the position of a cooking utensil on the hob from the interaction between the hob and the cooking utensil. This can enable the specific implementation, as already described above.
  • the present invention also relates to a hob for use in a cooking system as described above with a plurality of cooking zones, wherein at least one first cooking zone is assigned a first predetermined value of a cooking parameter and at least one second cooking zone is assigned a second predetermined value of the cooking parameter.
  • the present invention further relates to a cooking utensil for use in a cooking system as described above.
  • This makes it possible to provide a cooking utensil in order to be able to implement and use a cooking system as described above.
  • the cooking utensil preferably has at least one sensor for detecting a cooking temperature as a cooking parameter and at least one transmitter for transmitting the detected cooking parameter, the corresponding aspects described above can be implemented and used using this cooking utensil.
  • hobs are now known that offer a second operating state or operating mode in addition to the "normal assignment of power levels" operating state.
  • This second operating state is characterized by the fact that there are areas in the hob surface to which power levels are permanently assigned or which can also be changed by the user.
  • the second operating state can be called Move function, PowerMove, or something similar.
  • the maximum and minimum limits of the possible power levels to be set should be clear. It should also be ensured that areas remain in a logical order.
  • the display element can provide different information to the user.
  • the cooking parameters displayed may flash or be replaced by a special symbol.
  • the following message could be displayed: a symbol or text can be displayed.
  • acoustic signals can be emitted.
  • 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 Perpendicular to both the longitudinal direction X and the transverse direction Y there is a vertical direction (not shown), which can also be referred to as height 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.
  • Figure 1 shows a schematic plan view of a cooking system 1, 2 according to the invention according to a first embodiment.
  • Figure 2 shows the settings of the values of the cooking parameters of the three cooking positions 11a, 11b, 11c or cooking zones 11a, 11b, 11c of the hob 1 of the cooking system 1, 2 of the first embodiment.
  • the hob 1 is designed as a full-surface hob 1 and has a hob plate 10 in the form of a glass ceramic plate 10, on which several, for example two, three, four or five cooking utensils 2 can be placed.
  • Several jointly operated induction coils (not shown) below the hob plate 10 form cooking zones 11 as cooking points 11.
  • the hob 1 or its hob plate 10 with the induction coils underneath is divided into three equal parts, which are rectangular in shape and arranged parallel to one another.
  • the first cooking point 11a or cooking zone 11a faces the user at depth X.
  • the second cooking point 11b or cooking zone 11b and then finally the third cooking point 11c or cooking zone 11c follow at depth X, see Figure 1 .
  • the cooking surface 1 has a control element 12 and next to it a display element 13 as a liquid crystal display, on which, among other things, the value of a cooking parameter such as the power level of a selected cooking zone 11 can be displayed by an area as a cooking parameter display 13a. Furthermore, an area of the liquid crystal display of the display element 13 can symbolically display the selected cooking zone 11 as a cooking zone display 13b or as a cooking zone display 13b, see Figure 2 .
  • a cooking utensil detection system (not shown) is provided, which can be arranged, for example, as an optical detection system above or behind the hob 1 and can be aligned with the hob 1.
  • cooking utensil detection can also be carried out by the hob 1 itself by briefly operating the individual induction coils, as a "ping", so to speak, in order to detect whether or not a cooking utensil 2 located above the induction coils is present through its inductive coupling.
  • the values of the power levels of the three cooking zones 11a, 11b, 11c can be fixed in a corresponding operating state or operating mode of the cooking zone 1, so that a cooking utensil 2, here as a pot 2, can be placed or pushed by the user onto one of the three cooking zones 11a, 11b, 11c, recognized by means of the cooking utensil detection and automatically operated by the cooking zone or its control unit (not shown) at the predetermined power level, so that the user no longer has to select the power level of the cooking zone 11a, 11b, 11c and no longer has to switch on the cooking zone 11a, 11b, 11c.
  • the first, front cooking zone 11a has the highest cooking parameter value with the power level "9", so that the user can monitor the comparatively intensive cooking process more easily and/or stir, turn and the like the food more easily and quickly, which may be required more often than with lower settings due to the comparatively intensive cooking process.
  • the second, middle cooking zone 11b has the medium cooking parameter value with the power level "5".
  • the third, rear cooking zone 11c has the lowest cooking parameter value with the power level "3.5", so that a cooking process can take place there which will hardly require any intervention by the user in the cooking process such as stirring or turning the food.
  • FIG 3 shows a schematic plan view of a cooking system 1, 2 according to the invention according to a second embodiment.
  • Figure 4 shows the settings of the values of the cooking parameters of the three cooking zones 11a, 11b, 11c of the cooking surface 10 of the cooking system 1, 2 of the second embodiment.

  • the three cooking zones 11a, 11b, 11c are parameterized as in the first embodiment.
  • the control unit of the cooking zone 1 can check the parameter change desired or made by the user and only allow and implement the change if certain conditions are met or if certain exclusions are not present. This can be done by taking into account a dependency or relationship between the value of the power level of those cooking zones 11a, 11b, 11c whose value is to be changed and at least one other cooking zone 11a, 11b, 11c.
  • the first cooking zone 11a only a value that is equal to or lower than the value of the power level of the first cooking zone 11a can be permitted as the changed value of the power level of the second cooking zone 11b. Also, only a value that is equal to or higher than the value of the power level of the second cooking zone 11b can be permitted as the changed value of the power level of the first cooking zone 11a. For example, only predetermined higher values than for the second cooking zone 11b can be permitted or selected as the values of the power level of the first cooking zone 11a. In any case, it can be ensured that the first cooking zone 11a always has the highest power level, either alone or together with the second cooking zone 11b.
  • a notice may be displayed to alert the user to this and allow them to make an permissible change.
