Definitions

  • Hob with a screen and method of operating a hob
  • the invention relates to a hob with a screen according to the preamble of claim 1 and to a method for operating such a hob according to the preamble of claim 6.
  • So-called matrix cooktops with a large number of heating elements are known from the prior art, which can be flexibly combined to form different heating zones.
  • the heating zones are adapted to the size and / or shape of a cookware element that can be freely positioned by the operator on the hob. Because of the freely selectable by the operator tray level, which can also be changed by moving a cooking pot, a fixed assignment between Heizzo- nen and switching elements for adjusting a heating power of this heating zone is very difficult or impossible.
  • the use of touch screens to operate these heating zones is relatively complicated, since the operator first has to select a heating zone whose settings are to be changed, and then has to change the settings. Touch screens are also very expensive and difficult to operate, especially with dirty fingers.
  • the invention is in particular the object of making the operation of a generic hob simple and intuitive, without having to use a touch screen.
  • the invention is particularly based on a hob with a plurality of heating elements, which are preferably arranged in a grid with 4 x 4, 6 x 6 or 8 x 8 or more points.
  • the otherwise uniform grid may be interrupted in an area of a user interface.
  • the cooktop further comprises a detection arrangement for detecting a position and / or size of a cookware element, a control unit which forms a heating zone adapted to the position and / or size of the cookware element and assigns one or more heating elements to the heating zone.
  • a user interface comprises a screen with a plurality of switching elements arranged next to the screen.
  • the control unit includes a driver for driving the screen and is programmed to generate in at least one operating mode a screen display containing at least one icon of a heating zone.
  • the pictogram illustrates a position and / or size of the heating zone.
  • the screen display contains an icon associated with the icon of the heating zone, which assigns the heating zone to one of the switching elements.
  • the symbol is an arrow pointing to the switching element and / or to the icon.
  • the arrow can have one or two points and have many conceivable shapes. Furthermore, it is conceivable to represent the symbol as a simple line or the like.
  • the symbol in a further embodiment of the invention is proposed to form the symbol as a circle segment, which is arranged concentrically to the icon.
  • the circle segment represents an angular range in which the switching element is arranged with respect to a center of the screen. If, for example, the circle segment represents an upper left section of a circle or ring, it can be intuitively detected that the upper left switching element is assigned to the relevant heating zone.
  • the control unit assigns a switching element to each heating zone and, for this purpose, calculates the distances from the pictograms of the heating zones to the switching elements. The calculated distances are taken into account during the assignment.
  • the control unit may also include specially adapted hardware with storage space for storing the various distances.
  • the control unit calculates a distance between the free icon and the free switching element for each possible pairing between a free switching element and a free icon.
  • the pairings are arranged with increasing or decreasing distance.
  • the control unit selects the pairing with the shortest distance and assigns the switching element from the selected pairing to the icon of the selected pairing.
  • the selected switching element and the selected pictogram or heating zone are then no longer "free" in the sense of this method, and all pairings comprising one of these elements are deleted from the list of pairings with the remaining free switching elements and free icons repeated until all the icons are assigned to a switching element.
  • Another aspect of the invention relates to a method of operating a cooktop having a plurality of heating elements.
  • the method includes detecting a position and / or size of a cookware element, forming at least one heating zone adapted to the cookware element depending on the detected size and / or position of the cookware element, and associating one or more heating elements with the heating zone.
  • a screen image is generated on the screen of a user interface.
  • the user interface comprises a plurality of switching elements arranged next to the screen.
  • the screen display comprises at least one icon of a heating zone, which illustrates a position and / or size of the heating zone on the hob.
  • the screen display contains the symbol associated with the icon of the heating zone, which assigns the heating zone one of the switching elements.
  • FIG. 1 shows a hob with a plurality of heating elements, a control unit and a user interface
  • FIG. 2 shows the user interface of FIG. 1 in a first embodiment of the invention
  • Fig. 3 shows the user interface according to an alternative embodiment of the invention.
  • Fig. 4 shows the user interface of the hob according to a further alternative embodiment of the invention.
  • Fig. 1 shows a hob with a plurality of heating elements 10, a control unit 16 and a user interface 20.
  • the control unit 16 operates the user interface and operates the heating elements 10, which are formed as inductors.
  • the control unit 16 uses the heating elements 10 as inductive sensors for detecting cooking utensils 14 and summarizes those heating elements 10, which are at least partially covered by a bottom of the cookware element 14, to a freely configurable heating zone 18, in size and position adapted to the size and position of the cookware element 14.
  • the control unit 16 therefore forms, together with the heating elements 10, a detection arrangement 12 for detecting a cooking element 14.
  • the user interface comprises a screen 22 and a plurality of switching elements 28a-28f arranged next to the screen, as well as further switching elements 30 at a front edge of the hob are arranged. Both the screen 22 and the switching elements are covered by a cover plate 32.
  • the switching elements 28a-28f are capacitive switching elements that are directly under the Ab- cover plate 32 arranged sensors.
  • the resolution of the screen is at least 160x120 pixels.
  • FIG. 2 shows an electronic board of the user interface 20 without the cover plate 32. On the electronic board are both the screen 22 and the sensors the switching elements 28a - mounted 28f.
  • the screen display comprises one icon per heating zone 18 or per heated cookware element 14.
  • five cooking pots are placed on the hob, so that the control unit 16 forms five heating zones 18 which are shown as pictograms 24 in the form of circles are shown on the screen 22.
  • Each icon 24 is associated with a symbol 26, which is designed as an arrowhead, which points from the icon 24 to one of the switching elements 28a - 28f, thus allowing an optical association between the icon 24 and the relevant switching element 28a.
  • the icon 24, which is assigned via the symbol 26 to this switching element 28a is optically highlighted (for example by a full-surface representation of the circle).
  • a heating power of the heating zone 18, which is symbolized by the selected icon 24, can be increased via an incrementing key 34 or reduced via a decrementing key 36 of the user interface 20.
  • FIG. 3 shows an alternative embodiment of the invention, which differs in the shape of the symbols 26 from the embodiment according to FIG. 2.
  • the symbols 26 are arrows that point from the switching elements 28a-28f to the respective icon 24.
  • the symbols 26 are circle segments which are each arranged concentrically with the icon 24 to which the symbol 26 is assigned.
  • the circle segment represents an angular range in which the switching element is arranged with respect to a center of the screen 22.
  • the symbol 26 forms the upper edge of a circular ring so that the user can intuitively detect that the upper left switching element 28a associated with the relevant icon 24 and the respective heating zone 18.
  • a number may be indicated on the symbol 26, which corresponds to a number 38 which is printed on the cover plate 32 as a 7-segment display or as an imprint in the area of the switching element 28a.
  • the control unit 16 To associate the heating zones 18 and icons 24, respectively, with the various switching elements 28a-28f, the control unit 16 forms a list of all possible pairings of free switching elements 28a-28f and pictograms 24. If M switching elements and N icons are available, M x N results pairings. For each of these pairings, the control unit 16 calculates a distance between an edge of the icon 24 and the switching element 28a-28f of the pairing. For this purpose, the control unit 16 accesses a memory in which the positions of the switching elements 28a-28f are stored as a two-dimensional vector relative to the screen plane.
  • the distance between the switching elements 28a-28f and the edge of the icon 24 results from the subtraction of a circle radius of the icon 24 from the distance of the centers of the icon Switching element 28a - 28f and the
  • Pictogram 24 The distances thus determined are ordered by the control unit 16 in a list of size and the pairing with the smallest distance is selected.
  • the association between the switching element 28a-28f and the icon 24 is determined. Accordingly, in the embodiment shown in FIGS. 2-4, the assignment of the upper left icon 24 to the upper left switch element 28a would be determined first. Subsequently, all pairings containing either the selected switching element 28a or the selected icon 24 are deleted from the list and again the pairing with the shortest distance from the remaining pairings is selected. This selection process is repeated until all the icons 24 are associated with one of the switching elements 28a-28f.
