Definitions

  • the invention relates to a method for detecting cookware elements on a matrix hob according to the preamble of claim 1 and a matrix hob according to the preamble of claim 4.
  • an induction hob which comprises a detection arrangement for detecting a position and size of at least one cookware element and a control unit.
  • the control unit is configured to generate, using the inductors, an image of a bottom surface of a cookware element or a plurality of cookware elements mounted on the matrix hob.
  • the cookware element can be classified, for example, as an elongated or oval roasting pan or as a round cooking pot.
  • the control unit then summarizes a plurality of heating elements to a heating zone or a plurality of heating zones depending on a detected size and position of the cookware element.
  • the shape of the heating zone roughly corresponds to a basic form determined by the classification.
  • a hob that can detect and classify the shape of a cookware element for example, from DE 100 33 361 A1 known.
  • the control unit In the classification of cookware elements, the control unit relies on a limited repertoire of basic shapes and can therefore distinguish round cooking pots from oval fryers and rectangular pans. Difficulties arise in this approach, especially when several cookware elements are placed at a very close distance on the hob, so that the detection arrangement no longer records the cookware elements or their bottom surfaces as separate objects due to their limited spatial resolution, but as a contiguous area.
  • the obvious solution to this problem of providing a higher resolution detection device can not be realized with the inductors or heating elements of the hob and / or would normally be in which the cooking pots are placed at a significant distance from each other and a high resolution is therefore not necessary, too expensive.
  • the invention is in particular the object of providing a matrix cooktop and a method for detecting cookware elements on a matrix hob, which usually allows a separation of closely spaced cooking utensils without increased effort.
  • the invention is particularly based on a method for detecting cookware elements on a matrix hob.
  • the method includes generating a first image of a bottom surface of a cookware element or multiple cookware elements mounted on the matrix hob, and classifying a contiguous surface in the image of the bottom surface depending on the shape and / or size of the surface.
  • a pot separation algorithm be used to distinguish areas generated by a cookware element from areas created by two or more cookware elements. Since the pot separation algorithm is applied only after classification and only for certain results of the classification, the associated effort can be omitted in cases where this high cost would be inappropriate. As a result, tightly together cooking utensil elements can be safely separated without constantly having to perform a high-resolution detection and an elaborate pot separation.
  • Separate sensors or detectors can be dispensed with if the first image is generated by a detection arrangement that uses inductors of the hob as detectors.
  • the measurement data of the first image can be used by suitable image processing algorithms for a precise detection of the edges of the cookware elements.
  • an edge image of the contiguous surface is generated for separating area proportions, which are assigned to different cookware elements.
  • the first image can be generated by a dot matrix of measurement points in which each measurement point is assigned a measurement which is a parameter for a degree of coverage between the bottom surface of a cookware element and an environment of the measurement point.
  • the parameter may carry a higher information content if it is a non-binary value, in particular a percentage with one hundred or more possible values.
  • Another aspect of the invention relates to a cooktop having a plurality of heating elements, a detection arrangement for detecting a position and size of at least one cookware element and a control unit.
  • the control unit is configured to generate a first image of a bottom surface of a cookware element or multiple cookware elements positioned on the matrix hob to classify a contiguous surface in the image depending on the shape and / or size of the surface and depending on one detected size and position of the cooking utensil element to combine several heating elements to a heating zone or more heating zones.
  • control unit be adapted to apply, in at least one result of the classification, a pot separation algorithm to distinguish areas generated by a single cookware element from areas created by two or more cookware elements.
  • inventive method can be easily performed and the associated benefits can be fully utilized.
  • Separate sensors may be dispensed with if the heating elements are inductors and if the detection arrangement comprises the inductors for inductively detecting the cookware element.
  • the measured variables of the detection arrangement are each assigned to a measuring point on a hob surface, wherein the measuring points correspond to pixels of the first image.
  • a control unit 22 of the hob receives signals from a user interface 24, which also includes a display (not shown) and operates the inductors 10 depending on the settings made via the user interface 24.
  • 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.
  • the control unit 22 uses the inductors 10 for detecting the cooking pots 12, 14, so that the inductors 10 form a detection arrangement 26 together with the control unit 22.
  • the control unit 22 in particular can interconnect the inductors 10 with suitable capacitors to form a resonant circuit and generate an oscillating current by introducing a voltage pulse. From a decay of this current, the control unit 22 can calculate an attenuation constant. The greater the damping constant, the greater the degree of overlap between the respective inductor 10 and the cooking pot 12, 14.
  • other measuring methods may be used and / or separate sensors may be used.
  • Fig. 2 shows a cooktop with inductors 10 which are arranged in a skewed grid.
  • the grid has three translational symmetry directions, 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 19 which form a heating zone 16, 18, 20.
  • the control unit 22 of the hob usually assigns an inductor 10 then a particular saucepan 12, 13, 14, when the relevant inductor 10 is covered to more than half of the bottom of this cooking pot 12, 13, 14.
  • This rule occurs when, as in the in Fig. 2 illustrated situation, the cooking pots 12, 13, 14 can be clearly separated from each other in the coarse-meshed first image shown hatched. As in 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.
  • 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.
  • Fig. 3 schematically shows a situation in which two cooking pots 12, 14 were placed very close to each other on the hob, so that in connection with FIG. 2 rule described does not occur.
  • the inductors 10 are shown as square boxes and the more than 50% of a cooking pot 12, 14 covered inductors 10 are hatched and form in the in FIG. 3
  • the control unit In order to be able to operate the two cooking pots 12, 14 with heat outputs that can be determined independently of one another, the control unit must use the in coarse meshed first image shown in FIG FIG. 3 illustrated situation of situations in which only a single pan was placed on the hob.
  • 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 quantity or the field of the percentages forms the first image of the bottoms of the cooking pots, whereby the percentage values can be interpreted as gray values and the measurement points as pixels of the image.
  • 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 read whether the cookware element placed on the hob is a single pot (possibly a roasting pan) or two pots.
  • Fig. 4 Simple algorithms that have a centroid of in 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 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 control unit 22 determines from the in Fig. 4 a contiguous surface 28 of pixels (in Fig. 4 hatched), which are covered by a bottom surface of one of the cooking pots 12, 14. Subsequently, the control unit 22 determines characteristics for characterizing the contiguous area. When forming the characteristic quantities, the individual meshes or partial surfaces can be weighted with the measured values or the degree of coverage. Alternatively, the control unit 22 may calculate a development on an orthogonal function system on the two-dimensional plane. The parameters are used by the control unit 22, oval roasters of round pots and the in Fig. 4 and 5 be distinguished situation with two closely spaced pots.
  • control unit 22 can recognize that the surface 28 is likely to represent the bottoms of two different cooking pots 12, 14. The control unit 22 then classifies the first image accordingly as two cooking pots 12, 14. To the related Area 28, all pixels are summarized which have a non-zero coverage or a coverage that exceeds a predetermined threshold, and in addition have at least one adjacent pixel that also meets this criterion.
  • the measured variables determined by the detection arrangement 26 are used as parameters of a pot separation algorithm which uses methods from digital image processing.
  • the gray value image may ultimately be mapped to a binary image in which the image values are binary variables that indicate whether or not a bottom surface of a cookware element covers the pixel. In doing so, the in FIG. 4 percentages interpreted as gray values.
  • the control unit 22 may further determine an edge image of the contiguous area 28 of pixels, wherein a per se known edge detection method may be used. As a result, in particular the situation with two cooking pots 12, 14 can be distinguished from a situation with an elongated pot.
  • the pots 12, 14 can be separated from each other and the control unit 22 can, as in 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 shown in FIG. 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. These 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 depending on the power level set for the respective heating zone 16, 18.
  • the control unit 22 assigns the detected cooking pot 12, 14 to one of the categories “round”, “oval”, “rectangular” and determines in an optimization method the parameters of the respective geometric shape 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.
