Definitions

  • the invention relates to a hob with a plurality of heating elements and a detection arrangement for detecting a position and size of at least one cookware element according to the preamble of claim 1 and a method for operating a hob according to the preamble of claim 9.
  • Hobs with a plurality of heating elements are known from the prior art, which are of similar design and are arranged in particular in a grid or in a matrix.
  • Generic cooking hobs comprise a detection arrangement which detects cooking utensils placed on the hob.
  • a control unit of the hob evaluates the measurement results of the detection arrangement and summarizes groups of heating elements, which are arranged in the region of a detected cooking utensil element to largely freely definable heating zones together.
  • the size and shape of the heating zones is thus adapted flexibly to the user-freely selected position of the cookware and the size of the cooking utensil, while in classic cooktops with fixed heating zones, the heating zone is selected depending on the size of the cookware.
  • a control unit operates the heating elements combined to form a heating zone with a heating power which is determined as a function of a power level set via the user interface. If the user sets the highest power level, the heating elements of a heating zone are each operated at the maximum heating power, while at lower power levels, the heating elements are operated at a predetermined fraction of the maximum heating power.
  • an induction hob is known in which the total heating power of a heating zone is predetermined by the power level selected by the user.
  • the distribution of the total heating power to the individual inductors depends on the degree of coverage of the inductors by the bottom of the cooking pot to be heated. Since the sum of the degrees of coverage of the inductors of a heating zone also depends on the position of the cooking pot, this method also leads not to a completely location-independent surface heating power.
  • the calculation and regulation of the heating power is very expensive, since under certain circumstances, each of the inductors must be operated with a different heating power. The different heat outputs can easily lead to problems with flicker or intermodulation hum.
  • the total heating power of a heating zone is therefore dependent on the number of heating elements combined to the heating zone for the same power level selected by the user.
  • the heating elements are then usually assigned to a heating zone which is adapted to a particular pot when a degree of coverage between the bottom of this pot and the relevant heating element exceeds a predetermined strictly undergraduatedeckungsgrad.
  • the number of combined to form a heating zone heating elements depends on a position of the pot. For example, the same pot can cover three heating elements in a first position and, in a second position, cover four heating elements for more than the predetermined fraction.
  • the invention is therefore in particular the object of providing a generic cooktop with a plurality of heating elements and a detection arrangement for detecting a position and size of at least one cookware element, the control unit can determine a total heating of a heating zone at least largely independent of a position of the cooking utensil on the hob , Furthermore, the invention relates to a method for operating a hob, according to in which the total heating power can be determined independently of the position of a cooking utensil on the hob. More particularly, the invention relates to a cooktop having a plurality of heating elements, a user interface for inputting a power level, a detection arrangement for detecting a position and size of at least one cookware element and a control unit.
  • the control unit is designed to summarize a plurality of heating elements to a heating zone depending on the detected position and size of the cooking utensil element. Furthermore, the control unit determines a total heating power the heating zone depending on the input via the user interface power level and operates the heating elements accordingly with the thus determined total heating power.
  • control unit is designed to calculate from measured variables of the detection arrangement a bottom surface of the cookware element and to determine the total heating power depending on the bottom surface. While known hobs at best determine the number of heating elements that are not in a reversibly unique relationship to the bottom surface of the cookware element and determine the total heating power implicitly depending on the number of heating elements, the invention seeks to avoid the above problems, the immediate dependence of To avoid total heat output from the number of heating elements.
  • the bottom surface of the cookware element is determined in particular with a higher accuracy than would be possible by the mere counting of completely or partially covered by the bottom of the cookware element heating elements.
  • the controller may be further configured to determine the bottom surface of the cookware element at least partially independent of a number of the heating elements of a heating zone associated with the cookware element.
  • this partially independent determination of the floor area can be achieved by taking into account a correction factor, while further embodiments of the invention use methods borrowed from digital image processing and described in more detail below.
  • the invention can be used in particular in induction cooking fields, in which the heating elements are inductors. Since the inductors can be used simultaneously as sensors for detecting the cookware element, additional sensors of the detection arrangement can be saved.
  • the measurement is carried out by the detection arrangement in regular grid points, so that the measured variables of the detection arrangement are each assigned to a measuring point on a hob surface, wherein the measuring points form a measuring point grid.
  • the control unit is designed to determine the floor area with the aid of the course of the measured variables between these measuring points.
  • sensors in particular inductive sensors, in a certain way out of focus. If, for example, a maximum value of a measured variable means that the sensor is completely covered by the cookware bottom, and the measured value 0 means that there is no cookware bottom in a larger environment of the sensor, there will inevitably be a transitional area at the edge of the cookware bottom in which the measured variables Assume values between the maximum value and 0. The exact position of the edge can be determined by a suitable image processing method in this transition region with great precision.
  • the edges of the cookware elements can be detected with high precision by methods borrowed from digital image processing.
  • the control unit is designed to determine in such a binary image a coherent surface of pixels which are covered by a bottom surface.
  • control unit is adapted to an edge image of the contiguous surface of pixels determine so as to determine the shape of the bottom surface and / or the number of cookware elements arranged in the contiguous surface.
  • a situation with two closely spaced round pots can thereby be distinguished more clearly from, for example, a situation with an oval roasting pan.
  • the total heating power can be determined in a simple and reproducible manner by a multiplication of the ground surface thus determined with a maximum surface heating power and with a factor dependent on the power level.
  • the factor may describe a percentage of the heating power generated by the individual heating elements at the maximum heating power.
  • the surface heating power is a monotonically decreasing function of the floor surface. As a result, due to the geometric situation typically worse coupling of the heating elements to the bottom of smaller Cookware elements are compensated.
  • the effective coupling of the heating elements in the cookware tray is determined in smaller pots in particular by proportionally higher losses at the edge of the floor or the heating zone.
  • Another aspect of the invention relates to a method of operating a cooktop.
  • the method comprises the steps of detecting a position and size of at least one cookware element by a detection arrangement, combining a plurality of heating elements into a heating zone depending on the detected size and position of the cookware element, determining a total heating power of the heating zone depending on a set power level and operating the heating elements of the heating zone the total heat output.
  • the method further comprises calculating a bottom surface of a cookware element from measured variables of the detection arrangement, wherein the total heating power of the heating zone is determined depending on the bottom surface.
  • Fig. 1 schematically shows a cooktop with a plurality of heating elements formed as inductors 10, which are arranged in a grid.
  • the first cooking pot 12 five inductors 10 largely covers, while the second cooking pot 14 has a small pot diameter and only one inductor 10 completely covered.
  • the inductors 10 largely covered by the respective cooking pots 12, 14 each form a heating zone 16, 18 assigned to the corresponding cooking pot 12, 14.
  • a cooktop control unit 22 receives signals from a user interface 24, which also includes a display (not shown), and operates the inductors depending on the settings made via the user interface. In particular, a user may select a power level for each of the heating zones 16, 18 via the user interface 24. There are typically 16 to 18 different power level values available to the user.
  • Fig. 2 shows a cooktop with inductors 10 which are arranged in a skewed grid.
  • the grid has three axes of symmetry, each at an angle of 60 ° to each other, so that three adjacent inductors 10 are each arranged in an equiangular triangle.
  • cooking hob shown are three cooking pots 12, 13, 14 arranged in different positions.
  • the cooking pots 12, 13, 14 have circular bottoms of identical diameter.
  • Each of the cooking pots 12, 13, 14 is associated with a group of inductors 10, which form a heating zone 16, 18, 20.
  • the control unit 22 of the hob then assigns an inductor 10 to a particular saucepan 12, 13, 14, when the relevant inductor 10 is covered more than half of the bottom of the relevant saucepan 12, 13, 14.
  • Fig. 2 This is evident in the case of the cooking pot 12 for seven inductors, while in the case of the cooking pots 13 and 14 six or eight inductors 10 are covered to more than 50% of the corresponding cooking pot 13, 14. Since the cooking pots 12 - 14 have exactly the same diameter, shows FIG. 2 clearly that the number of inductors associated with the heating zone 16, 18, 20 of a cooking pot 12, 13, 14, not only on the size of the saucepan 12, 13, 14, but also depends on its position.
  • the control unit 22 uses the inductors 10 for detecting the cooking pots 12, 13, 14, so that the inductors 10 form a detection arrangement 26 together with the control unit 22.
  • the control unit 22 connects the inductors 10 with suitable capacitors to a resonant circuit and generates an oscillating current by the introduction of a voltage pulse. From a decay of this current, the control unit 22 calculates a damping constant. The greater the damping constant, the greater the degree of overlap between the respective inductor 10 and the cooking pot 12, 13, 14.
  • other measuring methods may be used and / or separate sensors may be used.
  • control unit 22 determines by suitable algorithm not only the number of inductors 10 combined to the respective heating zone 16, 18, 20, but also with an accuracy which greater than the achievable by the counting of the inductors 10 accuracy is the bottom surface of the cooking pots 12, 13, 14th
  • the heating powers of the heating zones 16, 18, 20 are determined by the control unit 22 as a product of the bottom surface of the corresponding cooking pot 12, 13, 14, a maximum surface heating power and a factor between 0 and 1, which is dependent on the power level set via the user interface ,
  • the value of this factor dependent on the power level is read by the control unit 22 from a table which is stored in a memory unit (not shown) of the control unit 22.
  • the power level B stands for "booster" and describes an operating mode in which the heating elements can be operated for a short time with a heat output that exceeds their nominal power.
  • a plurality of inverters or power output stages can be used in parallel with the operation of the inductors 10.
  • Fig. 3 schematically shows a situation in which two cooking pots 12, 14 were placed very close to each other on the hob.
  • the inductors 10 are shown as square boxes and the more than 50% of one or two of the cooking pots 12, 14 covered inductors 10 are hatched.
  • Fig. 4 shows the situation Fig. 3 (or a similar situation), wherein each of the inductors 10 is assigned a percentage value, which forms a measured variable and which describes a degree of coverage of the respective inductor 10 through the bottom of one of the cooking pots 12, 14.
  • the more than 50% of a cooking pot 12, 14 covered inductors 10 are shown hatched. From the hatched area alone, it is obviously difficult to tell whether the cookware element placed on the hob is a single pot (possibly a roasting pan) or two pots. Simple algorithms that have a centroid of in Fig.
  • Fig. 4 determine hatched area and would calculate a radius of the heating zone depending on a total area of the hatched area, would result in an obviously inadequate result of a single round heating zone, the Fig. 4 is shown as a dashed circle. Even a simple summation of the degrees of coverage would not allow a distinction between the two cooking pots 12, 14. A heating zone described by the dashed circle would not sufficiently heat any of the saucepans 12, 14 and would not allow independent power control of the two cooking pots 12, 14 either.
  • the measured variables determined by the detection arrangement 26 are applied to a pattern recognition algorithm known from image processing.
  • the control unit 22, with the aid of this pattern recognition algorithm can determine an edge image of a contiguous area of pixels, whereby a per se known edge detection method can be used.
  • the edge image is used to more accurately characterize the shape of the bottom surface and / or to determine the number of pots 12, 14 placed on the surface.
  • the situation with two pots 12, 14 can be distinguished from a situation with an elongated pot.
  • the pots 12, 14 can be separated from one another and the control unit 22 can, as in FIG Fig. 5 represented each of the cooking pots 12, 14 assign a separate heating zone 16, 18.
  • the bottom surface of the saucepans 12, 14 can also be easily determined after separating the cooking pots 12, 14, for example, as the area of the in Fig. 5 illustrated circles.
  • the heating zones 16, 18 defined in this way are then assigned by the control unit 22 in each case to different groups of inductors 10, which generate the heat output of the respective heating zone 16, 18. This assignment is in FIG. 5 shown. Inducers 10, which are overlapped by both heating zones 16, 18, remain inactive.
  • the control unit 22 determines for each of the heating zones 16, 18 a heating power in the manner described above and operates the corresponding heating zone 16, 18 associated inductors 10 so that in the sum of a certain total heating power is generated. This total heating power is calculated by the control unit 22 for each active heating zone 16, 18 in the manner described above, depending on the bottom surface of the cooking pots 12, 14 and on the power level set for the respective heating zone 16, 18.
  • the control unit 22 assigns the detected cooking pot 12, 14 one of the categories “round”, “oval”, “rectangular” and determines the parameters of the respective geometric shape in an optimization method so that the covered area is best described , In the case of round pots, the control unit determines the radius and calculates the floor area from the radius.
