Definitions

  • the invention relates to a hob with a hob plate and a method for operating such a hob.
  • a cooking vessel can be set up at almost any point on the heating area and heated by at least one underlying heating device, preferably also by two, three or even more.
  • an arrangement of known touch sensors or so-called touch switches can be provided. These can be arranged in an operating area and, for example, be arranged as capacitive touch sensors below an operating panel, which is advantageously formed by the hob plate.
  • other types of touch sensors are also known, for example optical, resistive, magnetic or with the action of force.
  • a touch-sensitive sensor field is provided as a longitudinal strip area for each hotplate, with touch sensors being arranged below the longitudinal strip area in order to form it.
  • touch sensors being arranged below the longitudinal strip area in order to form it.
  • only a single sensor field can be provided for all hotplates here.
  • an operating device for entering commands by touching or laying on a finger.
  • a longitudinal strip area with touch sensors arranged underneath for a corresponding stove is known, with precisely one such longitudinal strip area being assigned to each discrete and independent hotplate.
  • the vertical stripe areas are always all active.
  • a further hob with an operating method is known in which a heating area is divided into several strip-shaped sub-areas which run in the front-rear direction.
  • a heating area is divided into several strip-shaped sub-areas which run in the front-rear direction.
  • touch sensors underneath including a display of a power level, whereby a power level can also be changed in a known manner.
  • a further hob is known with a plurality of induction heating coils in a heating area.
  • longitudinal strip areas are arranged next to one another, as are known from the rest of the prior art and probably also have touch sensors underneath.
  • the operating lines as longitudinal strip areas are firmly arranged.
  • the invention is based on the object of creating a hob mentioned at the beginning and a method mentioned at the beginning for operating such a hob, with which problems of the prior art can be solved and, in particular, it is possible to ensure safe operation with a simple and reliable assignment to a to reach a certain hotplate.
  • the hob has a hob plate, a heating area and an operating area.
  • the heating area and operating area are advantageously formed on the hob plate or under the hob plate, and particularly advantageously they take up the entire surface of the hob plate.
  • the hob has an elongated operating device in the operating area, which extends in the direction along an outside of the hob plate.
  • the operating device has an operating panel, which can also be the hob plate, for example, in particular the only continuous hob plate. But this does not have to be the case.
  • the operating device can advantageously be arranged in the operating area in front of the heating area or in a front area of the hob plate, so that the operating area is arranged here.
  • an operating area can also be provided laterally to the left and / or right of the heating area, so that the elongated operating device in this case extends from front to back and not from left to right in front of the heating area.
  • the operating device has at least two longitudinal strip areas lying next to one another, which are arranged in extension to one another. This possible arrangement in extension to one another can either be exact, i.e. in exact extension, or also deviate from an exact extension by up to 5mm or 10mm as an offset. This can then still be viewed as an extension within the meaning of the present invention.
  • the longitudinal stripe areas next to one another can be the same length, but do not have to be.
  • touch sensors are arranged next to one another in the longitudinal direction of the longitudinal stripe area, which, so to speak, form the longitudinal stripe area.
  • Capacitive proximity sensors are particularly advantageous, but other functional principles are also possible, in particular optical contact sensors as a type of reflex light barrier.
  • At least two touch sensors are each assigned a lamp in order to be able to illuminate the position of this respective touch sensor and / or this touch sensor itself or to be able to display it by means of illumination. In this way, an operator can easily It is possible to indicate the point at which a finger has to be placed on top of the control panel in order to operate this touch sensor or the touch switch formed by it.
  • a light source is, for example, an LED. At least one light source is advantageously assigned to each touch sensor, so that, if necessary, all touch sensors can be illuminated.
  • each longitudinal strip area a number of touch sensors, which is less than the total number of touch sensors in this longitudinal strip area, can be activated next to one another without interruption to form a continuous touch-sensitive contact strip in such a way that a left end area and / or a right end area does not active or a non-touch-sensitive free area of the longitudinal strip area is formed.
  • the contact strip can therefore be arranged on the far left, then a non-active or non-touch-sensitive free area is formed on the right end area on the right, and vice versa. It can also be shifted to the center or towards the center in such a way that an inactive or non-touch-sensitive free area is formed both on the left and on the right, i.e. at least one touch sensor is not active and thus does not contribute to the touch strip.
  • a contact strip can be created as a type of operating element for the operating device, which can be shifted or positioned to a certain extent to the left or to the right within the associated longitudinal strip area. It may be possible, as will be explained further below, for the contact strip in its position, for example to the entire hob or to the other longitudinal strip area or contact strip, to depict a relative position of a cooking vessel with a hotplate on the heating area. It is shown in a very simple and intuitive way for an operator that this hotplate can be set in terms of its power, for example, with this touch strip, that is to say can be generally operated.
  • Such contact strips are also known as sliders, see for example the DE 102004044355 A1 or the DE 102013214164 A1 .
  • heating means for standing cooking vessels can be arranged in the heating area under the hob plate. They can be distributed over a large area with such a distribution that a cooking vessel can in principle be placed at any location in the heating area. At this location of the attached cooking vessel, a hotplate is then formed for heating the cooking vessel by a number of heating means arranged underneath, for example induction coils or radiant heaters, essentially determined by the covering of the cooking vessel. Such a hotplate should then be able to be operated by means of a longitudinal strip area of the operating device or a contact strip formed and positioned therein.
  • detection means are provided for detecting a position of a cooking vessel placed on the hob plate or on the heating area.
  • heating means in the form of induction heating coils
  • these can be the induction heating coils themselves, possibly supported by additional so-called pot detection sensors, advantageously also in coil form, for example in accordance with the EP 3 079 443 A1 same applicant. It is also possible for only such pot detection sensors to be provided.
  • the detection means can pass the information on to the operating device via a detected, set-up cooking vessel, so that that contact strip within the longitudinal strip area with which the power of a hotplate formed at the position of the detected cooking vessel can be adjusted is positioned along the longitudinal strip area.
  • the contact strip is then positioned either on the left or on the right within the longitudinal strip area in accordance with a position of the hotplate in a left area or in a right area of one half of the heating area.
  • the positioning of the contact strip within the longitudinal strip area can be graded and this can then be selected according to a position of the hotplate within this half of the heating area.
  • the adjacent longitudinal strip area with its displaceable contact strip is advantageously responsible and provided for the other half of the heating area.
  • a third longitudinal strip area can also be provided in the longitudinal direction of the two existing longitudinal strip areas in order, so to speak, to be able to divide the heating area along this direction not only into two areas, but into three areas.
  • This is advantageous, for example, in the case of wide hobs with a width of 90 cm, in which three cooking vessels can be placed side by side and not just two.
  • a longitudinal strip area is responsible, so to speak, and the position of the set up cooking vessel within this area of the heating area is then mapped or reproduced as well as possible by appropriately positioning the contact strip within the longitudinal strip area.
  • a cooking vessel is located exactly between two adjacent areas of the heating area, so that it cannot be said exactly which of two adjacent corresponding longitudinal stripe areas should be responsible, so to speak, then either a fixed assignment can be made that then always the left or always the right longitudinal stripe area responsible is.
  • it can be checked whether a further cooking vessel is placed on the heating area in front of or behind this cooking vessel, in particular in the same area of the heating area or also relatively close to a separation between two areas of the heating area. If this cooking vessel in front of or behind it is not placed exactly on a dividing line between two areas, but is offset slightly to the left, for example, a corresponding left longitudinal strip area can be provided for this left-hand longitudinal strip area or the longitudinal strip area for the left area of the heating area. For the cooking vessel standing exactly on the dividing line, the right longitudinal strip area can then be provided in front of or behind it, so that these two cooking vessels can also be distinguished from one another very well and instinctively.
  • At least two longitudinal strip areas extending from one another are provided next to one another, possibly even three, and before that two or three longitudinal strip areas extending from one another parallel to them. So a total of four longitudinal strip areas can be provided, possibly even six longitudinal strip areas for particularly wide hobs.
  • a left rear longitudinal strip area and a right rear longitudinal strip area can particularly advantageously have the same position along the longitudinal direction of an outer side of the hob plate in its longitudinal direction as a left front longitudinal strip area and a right front longitudinal strip area. This means that two adjacent longitudinal strip areas are arranged in extension to one another and a front and a rear Longitudinal strip area are also arranged congruently, so to speak.
  • the longitudinal strip areas are advantageously arranged with their longitudinal direction along a front side of the hob plate, that is to say the entire operating device in an operating area in front of the heating area.
  • the detection means can be designed in such a way that they recognize whether a hotplate is located in a rear half of the heating area or in a front half of the heating area. Accordingly, one of the rear longitudinal strip areas or one of the front longitudinal strip areas can be determined for the power setting for this hotplate. In this direction, it is sufficient if two longitudinal strip areas are provided, since it is usually hardly conceivable with the normal depths of hobs and sizes of cooking vessels that three cooking vessels are placed one behind the other on the heating area. In the case of wide hobs, three cooking vessels can certainly be set up next to one another, which is why it can be advantageous here to provide three longitudinal strip areas next to one another.
  • a respective left longitudinal strip area is determined when the hotplate is in the left half of the heating area.
  • a longitudinal strip area on the right is determined when the hotplate is in the right half of the heating area. If the hob is divided in width into three areas of the heating area, then one of three adjacent longitudinal strip areas can be determined.
  • the detection means are designed in such a way that they compare the relative positions of several detected hotplates and thus also cooking vessels in the heating area with one another. In doing so, they set hotplates lying next to one another and hotplates lying one behind the other or in front of one another in relation to one another in such a way that one of the rear longitudinal strip areas or one of the front longitudinal strip areas is provided for their power setting.
  • the contact strip is then shifted to the left or to the right within the longitudinal strip area in such a way that, preferably viewed along this displacement direction, a center point of the contact strip is arranged as close as possible to the center point of the associated hotplate. This can apply alone to a component along this direction or also in general. In this way, the operator instinctively and easily grasp the assignment of a contact strip to a hotplate as being responsible for its operation.
  • At least one digit display preferably a seven-segment display
  • This numerical display is advantageous with two digits, so that two-digit power levels and also two-level timer information can be displayed.
  • Seven-segment displays are very simple number displays, but other designs can of course also be provided.
  • the numerical displays are advantageously provided on the same side for longitudinal strip areas lying one behind the other. It is particularly advantageous to provide numerical displays for all longitudinal stripe areas on the same side, for example to the right of it. Thus, the numerical display of one of these longitudinal stripe areas or both longitudinal stripe areas can be located between two adjacent longitudinal stripe areas.
  • the aforementioned lighting means can be designed to visually identify this contact strip after the contact strip has been arranged within the longitudinal strip area according to a relative position of a cooking area including the cooking vessel set up on the heating area, even before a power of the associated cooking area has been set.
  • the touch sensors of the touch strip or the touch strip themselves can be illuminated with a somewhat reduced luminosity of the illuminants, for example with 10% to 80% luminosity, preferably with 20% to 50% luminosity. The operator therefore sees a correspondingly positioned illuminated contact strip, as it is also generally known as a so-called slider.
  • the power of a hotplate is set below the maximum power level that applies to this hotplate, it can be provided, corresponding to a proportionate length of the touch strip, that the touch sensors are illuminated with high luminosity, starting from the left, according to this set length, advantageously 80% to 100% Luminosity.
  • the rest of the touch sensors or other touch sensors of this touch strip can then only be illuminated with the aforementioned reduced luminosity, which is advantageously below 50%, in order to achieve a clear visual differentiation from the strongly illuminated touch sensors according to the set power.
  • the touch sensors of the longitudinal strip area, which do not form the contact strip are not illuminated at all.
  • a previously operated contact strip with a set power which is represented in the previously described differently strong lighting of the contact strip, is reduced in its luminosity. It can advantageously be reduced to 50% luminosity of the illuminants or even less, this being done in such a way that the set power within the touch strip can be optically estimated based on the length of the relatively more strongly illuminated touch sensors. In this way it can be achieved that the touch strip on which an operation is currently taking place or which has taken place within a relatively short period of 10 seconds or 20 seconds before that is illuminated more intensely than the others.
  • the contact strip on the other cooking vessel or on the other cooking point can be shifted in its longitudinal strip area, advantageously in the opposite direction, although this cooking vessel or this cooking point has not moved.
  • This displacement of the two contact strips relative to one another has the meaning that a differentiation or relative assignment of the two hotplates to the respective contact strips may then be as great as possible.
  • a hob 11 according to the invention is shown with a hob plate 12 which has a front edge 13 or a front side at the front.
  • the structure of the hob 11 or the arrangement of an operating device 18 is oriented in a certain way along this front edge or front side.
  • the hob 11 or the hob plate 12 is divided into a large rear heating area 14 and a narrow front operating area 17, as indicated here by the long dashed line. In practice, this is not necessarily recognizable from above or is not specially marked, but it can be provided.
  • the heating area 14 is divided into four equally sized sub-areas 14a to 14d by dotted lines that form a cross. With a width of the hob 11 of approximately 60 cm, this corresponds to a conventional hob in which individual heating means are provided in each of the sub-areas 14a to 14d. Here, two heating means 15 are indicated by dashed lines for each sub-area 14a to 14d. This corresponds to the above-mentioned principle that cooking vessels can be placed as freely as possible on the hob 11, so that they can then be heated by such a heating means 15, depending on size and position, or by several up to four.
  • the dotted cross for dividing the heating area 14 into the sub-areas 14a to 14d is advantageously not marked on top of the hob plate 12 or the like.
  • an operating device 18 is arranged in the longitudinal direction along the named front edge 13 of the hob 11, specifically below the hob plate 12, which in this case then forms the control panel for it mentioned at the beginning.
  • the operating device 18 has four longitudinal strip areas 20a to 20d which are parallel to one another.
  • the two rear longitudinal strip areas 20a and 20b are arranged exactly in extension of one another, the two front longitudinal strip areas 20c and 20d also and exactly in front of the two rear longitudinal strip areas 20a and 20b.
  • a numeric display 24a to 24d is provided to the right of the longitudinal stripe areas 20a to 20d.
  • a longitudinal strip region 20 of the operating device 18 is shown schematically in a plan view. It consists of individual touch sensors arranged directly next to one another 22. These can then functionally interconnected to form a touch strip mentioned at the outset, for example nine touch sensors 22 next to one another corresponding to a division into nine different power levels, as is usual for cooktops.
  • the structural design of the longitudinal strip area 20 with the touch sensors 22 can, for example, be the DE 10 2013 214 164 A1 , the DE 10 2009 049 559 or the DE 10 2004 044 355 A1 correspond.
  • the touch sensors 22 are advantageously also illuminated, as can be seen from the aforementioned FIG DE 10 2013 214 164 A1 is known.
  • lighting could also be arranged behind or in front of the touch sensors 22 or the longitudinal strip area 20, but it is advantageous within the area of the individual touch sensors 22. This makes it possible to identify them as clearly and clearly as possible. Not all touch sensors 22 have to be illuminated, but advantageously at least those that may form the starting point or end point of a contact strip within the longitudinal strip region 20. In any case, these points should be marked with lighting.
  • a touch strip within the longitudinal strip area 20 of touch sensors 22, several of these touch sensors 22 can simply not be activated or evaluated by a controller or an operation by placing a finger on the hob plate 12 in the operating area 17 above has no effect. Where such a contact strip is then formed, for example, by nine contact sensors 22, is arranged within the longitudinal strip region 20 is the same or is open, as explained above. This is based on the following Figures 4 to 7 still clear.
  • the numeric display 24 is shown with two digits. A seven-segment display can be seen, which also has additional points, symbols or the like. to the right of the two digits.
  • the numerical display 24 primarily shows the power of an associated hotplate set on the longitudinal strip area 20.
  • FIG. 3 an alternative hob 111 according to the invention is shown in a wide design, which can be about 90 cm wide, for example.
  • the hob 111 has a hob plate 112 with a heating area 114. This is divided into six sub-areas by the dotted lines, ie has two more than the hob 11 with a width of about 60 cm from the Fig. 1 .
  • an operating device 118 is arranged with six longitudinal strip areas 120a to 120d.
  • the three rear and the three front are aligned lengthways to each other.
  • Longitudinal strip areas 120 lying one behind the other are exactly congruent.
  • a numeric display 124a to 124f is arranged to the right of each longitudinal strip area 120a to 120f.
  • FIG. 4 an exemplary configuration is shown in which four cooking vessels 26a to 26d are placed on the hob 11 or its hob plate 12. Three cooking vessels 26a to 26c are large, the cooking vessel 26d is rather small. However, this only plays a role for the space available and thus for the possible set-up locations, but not for the operating procedure.
  • the cooking vessels 26a to 26d are relatively well distributed over the individual sub-areas 14a to 14d, which is why the respective assignment to one of the longitudinal strip areas 20a to 20d is simple.
  • the cooking vessel 26a is located at the rear in the heating area 14 and in the left half, that is to say in the sub-area 14a, on the right. For this reason, in the longitudinal strip area 20a, a contact strip 21a identified by hatching is pushed to the far right.
  • This contact strip 21a then forms a control element or a previously explained slider according to the prior art, on which an operator can set a power for the cooking vessel 26a or the cooking position determined by its position, its height by placing a finger at a certain point in relation to the possible total power corresponds to the relative position of the finger between the left end and the right end of the touch strip.
  • a power level can be set or a power increase can take place by wiping over it in a direction from left to right. By swiping over from right to left, the power is reduced.
  • this is well known from the prior art.
  • the right rear cooking vessel 26b is clearly arranged in the right rear area of the heating area 14 or fully in the sub-area 14b, but protrudes a little over the horizontal dotted line forwards into the sub-area 14d. This does not interfere, so the longitudinal strip area 20b is clearly responsible here or is defined for the operation. Because of the more central and only slightly to the right offset arrangement of the cooking vessel 26b a touch strip 21b identified by hatching, shifted slightly to the right from the center within the longitudinal strip area 20b. This means that there is a slightly shorter free space on the right than on the left.
  • the positioning of the contact strip 21b in the longitudinal strip area 20b also approximately reflects the relative position of the cooking vessel 26b in the left / right direction.
  • a front left cooking vessel 26c is arranged quite far to the left in the corresponding sub-area 14c.

  • the contact strip 21d provided for operating the cooking vessel 26d is also positioned on the far left.
  • Fig. 4 shown light hatching of the contact strips 21, which takes place in practice by the aforementioned lighting with a luminosity of advantageously 20% to 50% of the maximum luminosity, an operator is shown where exactly the contact strip as a control element or as a slider for operation or The power setting for the respective cooking vessel 26 is within the longitudinal strip area.

  • the cooking vessel 26a in the sub-area 14a protrudes with a significant portion to the right into the sub-area 14b.
  • this does not change the fact that it is still overall in the left half of the heating area 14 and thus one of the left longitudinal strip areas 20a or 20c is responsible.
  • the cooking vessel 26a is at the same time clearly arranged at the rear, the rear longitudinal strip area 20a is assigned.
  • a contact strip 21a provided therein is accordingly positioned on the far right.

  • An operator recognizes the set power level not only as a number, but also quasi geometrically through the length of the strongly illuminated contact strip 21a.
  • the cooking vessel 26b is arranged in the right rear sub-area 14b and shifted a little bit to the left from the center. That is why the corresponding contact strip is created 21b in the longitudinal strip area 20b also shifted a little bit to the left from its center.
  • the hotplate defined by the cooking vessel 26b is heated to the greatest possible extent. For this reason, the numerical display 24b shows a "9" as the power level, and the entire touch strip 21b is strongly illuminated and consequently strongly hatched.
  • the cooking vessel 26c is arranged relatively centrally in the front left sub-area 14c with a slight shift to the left. For this reason, the contact strip 21c in the longitudinal strip region 20c is also shifted a little to the left from the center.

Then, according to a rule explained at the beginning, an assignment can be made either to a left longitudinal stripe area or to a right Longitudinal strip area take place.
  • the operating device 18 or a control provided therein recognizes that two further cooking vessels 26b and 26c are present. The distance from the cooking vessel 26c is greater, and for this purpose the longitudinal strip area 20d is assigned in an easily recognizable manner. Within this, a rightmost touch strip 21d is placed, which is obvious.
  • the right rear longitudinal strip 20b is used.
  • the corresponding contact strip 21b is naturally positioned to the far left therein.
  • the longitudinal strip 20c is then used for the cooking vessel 26b, in which the contact strip 21c is again positioned on the far left.
  • FIG. 8 Another configuration is shown in which a very large cooking vessel 26c is set up in the right half of the heating area 14, predominantly in the rear area.
  • the rear right longitudinal strip area 20b is therefore assigned for this purpose.
  • the contact strip 21d is again arranged on the far right. In this respect, this corresponds more or less to the Fig. 4 and the Fig. 6 .
  • two equally large and rather small cooking vessels 26a and 26b are arranged in the left half of the heating area 14. They can be clearly distinguished with regard to left and right, but both in the left half. Furthermore, they cannot be distinguished in their arrangement with regard to the rear area or the front area in the left half. That is why it is not easy to assign them here.
  • a quasi-arbitrary assignment is chosen here in that a distinction is only made using the criterion left and right.
  • the rear longitudinal strip region 20a is assigned to the right cooking vessel 26b, and within it the corresponding contact strip 21a is then arranged on the far right.
  • the left front left longitudinal strip region 20c is assigned to the cooking vessel 26a arranged on the left.
  • the contact strip 21c is then shifted to the far left in accordance with the position relative to the cooking vessel 26b.
  • the left rear longitudinal strip 20a is then assigned to the cooking vessel 26b, the contact strip 21a being correspondingly positioned on the far right here.
  • the rule applies here that if there is not an assignment based on both criteria left / right and back / front can, simply some sort of assignment is made. However, this should then apply as a fixed rule, similar to the previous one Fig. 7 explained with the cooking vessel 26a. If two cooking vessels are located in one half of the heating area 14 at the same height with respect to the rear / front, the right cooking vessel is assigned the rear longitudinal strip area and the left cooking vessel is assigned the front longitudinal strip area. Of course, this also applies regardless of the size ratio of the two cooking vessels to one another.
