Definitions

  • the present invention relates to a method for operating a cooking field device and a cooking field device with which such a method can be carried out.
  • the invention relates to a cooking field device with an induction hob, wherein a plurality of induction coils generates the required heating energy and emits by induction to the bottom of the pot positioned on the hob.
  • graphical displays can be used which have a plurality of display points on a display surface and thus a positioned on the hob pot, for. Mapping true to scale so that the user can directly see which pot is located where.
  • the inventive method for operating a cooking field device is performed with a hob having a plurality of induction coils and a smaller and predetermined number of display units. Each display unit is associated with a predetermined surface portion of the hob. Each display unit serves to indicate an operating state of an associated cooktop zone.
  • a detection device a pot position is detected on the hob, and there are identified by the pot at the current pot position covered induction coils. From the positions of the currently identified induction coils, a representative detection point for the current pot position is determined. On the basis of the position of the representative detection point, the associated predetermined surface section of the hob is determined, and the current display unit associated with the predetermined surface section is determined.
  • a significant advantage of the method according to the invention is that a discrete and predetermined and usually quite small number of display units is used to represent the operating conditions of a discrete number of cooking surface zones, each cooking surface zone may have a plurality of induction coils.
  • a cooktop zone is preferably substantially or at least partially associated with the surface section.
  • the coordinates of the Center of the detected induction coils can be used.
  • a weighting with the area of the covered induction coils is used to make a geometric weighting.
  • a covered induction coil is in the context of the present invention, an induction coil, which is covered to a considerable extent by a pot. This means that when operating a covered induction coil, this induction coil induces energy in the pot bottom to a considerable extent. Alternatively, it is possible to approximate a geometric overlap. Thus, a coil is considered covered if it appreciably or even covers the bottom of the pot in the vertical direction.
  • the cooktop in the context of the present invention is a ceremoniesnkochfeld, in which the surface portions and the cooktop zones are arranged in particular in rows and columns.
  • the number of induction coils is preferably considerably larger than the number of input units for operating the cooking field device. It is possible and preferred that the number of input units corresponds to the number of cooktop zones. But it is also possible that a small number and z. B. also serves only a single input unit to operate all cooktop zones.
  • At least one pot parameter is determined from the number and positions of the currently identified induction coils.
  • a geometric image of a pot positioned on the hob can be determined. If the induction coils are relatively small in relation to the dimensions of the pot bottom and a corresponding number of induction coils are used and arranged relatively dense, a relatively accurate geometric shape of the pot bottom geometry and a correspondingly accurate pot dimension can be determined.
  • the degree of overlap of the individual induction coils can also be taken into account in order to determine a pot bottom geometry and / or a pot dimension.
  • a measure of a degree of coverage may be determined by taking into account the power output of an induction coil compared to its power setting.
  • An induction coil completely covered by the bottom of the pot emits more power at a given setting than an induction coil, which is covered, for example, only half or a quarter of a pot bottom.
  • the ratio of the active power to the apparent power of a coil for determining the coverage.
  • the phase relationship between coil current and coil voltage is a measure of the overlap and can be evaluated.
  • Such cover values can in turn be used to determine the pot size and pot geometry or pot parameters.
  • At least one pot parameter is taken into account for determining the currently representative detection point. If, for example, based on the number, position and degree of coverage of the identified induction coils, it is concluded that the bottom of the pot is circular, then this information can be used to determine a meaningful representative detection point. If, on the other hand, it is determined that the pot bottom geometry is more rectangular or elongated rectangular, then this information can also be used to determine a meaningful representative detection point.
  • a new representative detection point is determined. It is also possible for a new representative detection point to be determined at fixed or variable time intervals. Thus, it can be ensured that changes in the operation are recognized in good time, at least if the time interval between two successive determinations is sufficiently small to detect dynamic processes. Time intervals between measurements in the second or millisecond range are possible.
  • the associated display unit when the representative recognition point changes, is redetermined and activated when the associated display unit has changed. For example, it is possible that a pot is first detected on a particular cooktop zone. If the user deliberately or unconsciously shifts the pot positioned, for example, at the edge of the cooking surface zone during the cooking process, the pot can be moved from the first cooking surface zone, for example, into the second cooking surface zone.
  • the display unit of the first cooktop zone is deactivated and the display unit of the second cooktop zone is activated. In a corresponding manner, in each case the previous display unit is deactivated and the newly assigned display unit is activated.
  • the pot position is updated and it will maintain the set power level, even if the surface section is changed.
  • the set power level and other set parameters are maintained, although the associated cooktop zone has changed.
  • the respectively covered induction coils of the now second cooktop zone are activated, while the no longer covered induction coils in the first cooking surface zone are disabled.
  • the display unit of the second cooktop zone is activated. In any case, it is possible that a pot is heated with indication coils from different surface sections.
  • Such a configuration is very advantageous because it greatly facilitates the cooking process for the user and makes a large number of settings superfluous. In many cooking processes, it can happen unintentionally or intentionally that a pot leaves a cooking surface zone. With this embodiment of the method according to the invention a manual activation of the induction coils in the second cooktop zone is not necessary, but the power level once set follows the pot, even if the pot leaves the first activated cooktop zone.
  • the current covered by the pot induction coils are operated according to the set power level. It is possible and preferred that after each change in position of the pot, the respective power output of each currently covered by the pot induction coils is adjusted. This is possible if the pot is moved within a cooktop zone. This is also possible if the pot is moved or displaced from one cooktop zone to another cooktop zone.
  • the power output of each currently covered by the pot induction coils is set so that the sum of the power outputs of the covered induction coils at least substantially equal to the set power level. Possible deviations are, as they are common in the prior art.
  • a signal is output when the power output of each currently covered by the pot induction coils falls below or exceeds the set power level by a predetermined value.
  • the respective power of the individual induction coils is preferably reduced accordingly.
  • a signal is preferably output from the associated display unit.
  • the display unit may be lit by a flash signal having a predetermined clock frequency or a certain rhythm, or may also output a sound signal or another signal in order to alert the user to the current situation.
  • the current display unit is checked after each change in position of the pot and adjusted if necessary.
  • the set power level is stored for a predetermined period after lifting or after removing the pot.
  • the previously set power level again set or remains set, in particular at least when the restart is detected within the predetermined period.
  • a predetermined period may be, for example, 60 seconds or even 2 minutes, 5 minutes or 10 minutes or the like.
  • the power level also be maintained when the pot is placed on another surface portion.
  • information for pot detection can be stored.
  • Such information may in particular be the temperature of the pot, a phase position of the inductor current, an inductor current, a pot size and a Topfart.
  • Other parameters of the pot can also be used.
  • the pot can be reliably detected, for example, reliably over the temperature of the pot, the bottom of the pot and the pot dimensions, so that even after removing a pot and restarting the pot is reliably recognized again to allow further operation, in which no User input must be made.
  • the currently assigned display unit outputs a signal when the currently assigned display unit is set. This is done for example after the first recognition of a pot in a cooking process. If the currently assigned display unit is specified, preferably a power level for the currently assigned cooktop zone can be selected. Such an operating mode is particularly advantageous if a common input unit is provided for a plurality of cooktop zones.
  • a signal may be, for example, a flashing light, flashing or change of color to alert the user.
  • the method is carried out simultaneously when using multiple pots and also when using multiple pots.
  • the individual pots can then be reliably distinguished from each other.
  • a cooking field device has a hob, which is associated with a plurality of induction coils and a smaller and predetermined number of display units. Each display unit is associated with a predetermined area portion of the hob and each display unit serves to indicate an operating state of an associated cooking area zone.
  • a detection device is provided which is suitable and arranged to detect a pot position on the hob and to identify the induction coils covered by the pot at the current pot position and to determine a representative detection point for the current pot position from the positions of the currently identified induction coils , In this case, the detection device is furthermore suitable and set up to determine the associated surface section of the hob based on the position of the representative detection point and to determine the current display unit assigned to the surface section.
  • the cooking field device has a plurality of induction coils per cooking surface zone.
  • the number of induction coils per cooktop zone is preferably less than or equal to 2. It is possible and preferred that each induction coil is assigned to exactly one cooktop zone. But it is also possible that individual induction coils are each associated with two cooktop zones when the boundaries of the surface sections intersect the surfaces of the induction coils. Even a flexible assignment during operation is possible.
  • the invention allows the operation of a hob, in which the power output is associated with the pot and no longer with a cooking or cooking surface zone.
  • a cooking field device is used which has more induction coils than display positions or display units.
  • On the display units are each a display element and optionally an input unit for adjusting the power for each cooking surface zone. Or there is provided an input unit for adjusting the power of all cooktop zones.
  • the user puts a pot on the hob of the hob field.
  • the hob can have no mark for positioning the pot.
  • the detection device of the cooking field device detects the position of the pot and calculates the associated display unit from the number and the positions of the covered coil devices.
  • the associated display unit lights up and thereby signals the input readiness to the user.
  • the user can then select the power level.
  • the corresponding power is delivered to the pot. If the user now shifts the pot to any other position (not only within the cooking surface zone) on the hob as a whole, then recognizing the cooking field device detects the displacement and recalculates the position of the pot.
  • the display unit of the other cooking surface zone is activated while the display unit of the previously active cooking surface zone is deactivated.
  • the power level is set automatically at the new position on the new cooktop zone. It is advantageous that the user does not have to make any further inputs, but that this process takes place automatically when moving a pot.
  • the display setting will not change and the same display unit will remain active.
  • the power delivered to the pot is recalculated and it may be that other induction coils are activated or operated at a different level.
  • the cooking field device can not balance the power, it may provide a suitable signal, e.g. emit a flashing on the display unit or a buzzer or the like sounds to alert the user that the set power level is not reached.
  • the pot bottom geometry such as the length, width and diameter of the pot, can be used.
  • the number of induction coils and the area dimensions of the active induction coil and the number of display units and the position of the display units and the active Koch vomiretician can be used.

Accordingly, the display unit 8 of the associated cooktop zone 28 is activated. Regardless, however, the induction coils 51, 52 and 53 are activated to deliver the previously set power level with a defined power to the pot 10. To a corresponding extent, the power of the individual induction coils 51, 52 and 53 is adjusted.
