Description

The invention relates to a cooking device. In particular, the invention relates to a cooking device comprising a hob composed of several surface sections and a heating device with several heating units for heating pots that are positioned on the hob, each heating unit being assigned to at least one surface section. For the flexible use of different pots with different pot bottom dimensions and geometries on the hob, it is advantageous if each heating unit is assigned to at least one surface section so that one or more heating units covered by the pot can be active when heating a pot positioned on one or more surface sections which are assigned to the surface unit or units on which the pot is positioned ie which are occupied by the pot. As a result, not only a certain type of pot and pot size can be used on one or more surface sections, but they are also suitable for a wide variety of pots.

A detection device of the cooking device serves to recognize the position of pots on the hob and to identify one or more occupied surface sections on which or on which pots are positioned. As a result, each heating unit assigned to an occupied area segment can be switched to active when a pot is recognized on the area segment assigned to it. The recognition device can be designed to directly recognize and identify an occupied surface section and / or to recognize and identify it indirectly by recognition and identification by means of a heating unit, this heating unit being assigned to the occupied surface section. The detection device is adapted to the heating device with its sensor system in order to directly and / or indirectly detect and identify one or more occupied surface sections.

A display device of the cooking device is used to display the operating state of the occupied area or sections and / or the associated heating unit (s). It is known from prior art that is not documented in print that the display has a display area which corresponds to a reduced hob area of the hob. The display device is designed to display a pot recognized by the recognition device on the occupied surface section or sections by means of at least one geometric element in a region of the display surface that is assigned to the occupied surface section or sections of the hob.

In order to enable an unambiguous and directly visible assignment of a pot positioned on the hob to one or more surface sections, graphic displays can therefore be used which have a large number of geometric elements on a display surface and thus a pot positioned on the hob, for example true to scale map so that the user can see directly where each pot is located. However, it is sometimes difficult and not very intuitive for the user to recognize which operating parameters are set for a specific pot that occupies one or more surface sections, or to change a set operating parameter. The document WO2009 / 053279A1 shows a cooking device according to the preamble of claim 1.

The invention thus has the problem of providing a cooking device which has an improved display device. In particular, a cooking device is to be provided in which a user can clearly and intuitively identify operating parameters of a pot positioned on the hob and assign them unambiguously. According to the invention, this problem is solved by a cooking device having the features of claim 1. Advantageous configurations and developments of the invention emerge from the following subclaims.

The advantages that can be achieved with the invention are, in addition to a display of operating parameters for a pot that occupies one or more surface sections, that the user can grasp the operating parameters at a glance and clearly assign them to the pot. The cooking device provides the user with status information for each hotplate at a glance.

According to the invention, it is provided that the geometric element is designed as a line element with a dividing line, having sub-areas on both sides of the dividing line and that the display device is designed to display a plurality of operating parameters of the occupied area or sections in the sub-areas of the geometric element. This ensures a clear and unambiguous display of the operating parameters for the user and enables the user to clearly assign them to a pot. A clear and intuitively understandable metaphor of the real situation on the hob is provided by means of the design of the display device.

Different technologies such as halogen heaters or induction coil (s) and their combinations can be used for the heating device. The cooking device can, for example, have full-surface induction, zone induction / halogen, temperature-controlled hobs and combinations thereof. The heating unit is preferably a heating coil and can be used as an indirect heating coil in the form of an induction coil or as a direct heating coil in the form of a heating coil, for example a metal heating coil or a halogen heater or a halogen incandescent lamp. The cooking device can be any known type of stove. However, the cooking device is preferably an induction cooker. The hob is preferably a full-surface induction field and the heating units of the heating device are designed as a plurality of induction coils which generate the required heating energy and emit it by electromagnetic induction to the bottom of the pot positioned on the hob.

The detection device for detecting the position of pots on the hob and for identifying one or more occupied surface sections on which or on which pots are positioned can be designed to recognize and identify a degree of coverage of a heating device and / or a surface section. If several surface sections are occupied by a pot, they form a cooking surface zone. If a surface section is only partially occupied by the pot, it is considered to be occupied by it if it is covered to a considerable extent by the pot or is significantly covered in one direction.

The display device has a display area which corresponds to a reduced hob area of the hob but is otherwise preferably true to scale. This means that it has a proportional length and width ratio like the hob, but is reduced in size. Preferably the surface sections from which the hob is composed are in rows and columns, i.e. arranged in a matrix. The display area also preferably has areas which are also in columns and rows, i.e. are arranged in a matrix, so that each area of the display surface is assigned to a surface section of the hob.

According to the invention, the line element has a transverse line which runs at an angle to the dividing line and thus defines further subregions of the line element. The transverse line is preferably arranged perpendicularly or essentially perpendicularly to the dividing line. Furthermore, the dividing line and the transverse line preferably intersect in the middle and thus form a cross. With regard to its position on the display area, the center point of the transverse line and the dividing line preferably corresponds to the location of the center point of the recognized pot on the hob.

The operating parameter is preferably selected from the group consisting of

• Operating temperature to be set for a pot occupying one or more surface sections,
• Residual heat duration of one or more heating units and / or one or more surface sections,
• Residual heat output level of one or more heating units and / or one or more surface sections,

• On-off status of the operating temperature to be set,
• On-off state of the booster level,
• On-off state of an automatic parboil and / or
• On-off state of a keep warm function.

By displaying several of the operating parameters at the depicted location of the pot on the display surface, the user receives intuitively clear and comprehensive status information for this pot.

Preferably, one of the displayed operating parameters is the operating temperature to be set or the power level and another displayed operating parameter is the remaining heating time. In a preferred embodiment, one of the displayed operating parameters is also a residual heat output level or the residual heat temperature and another displayed operating parameter is the residual heat duration. One of the displayed operating parameters is preferably the remaining heating time or the remaining heating time. One of the displayed operating parameters is preferably the on-off state of the power level, if another displayed operating parameter is the power level, the on-off state of the operating temperature to be set, if another displayed operating parameter is the operating temperature to be set, the on-off state the booster level if the Another another displayed operating parameter is the booster level, and / or the on-off status of a keep warm function.

In a preferred embodiment, a length extension and an alignment of the geometric element depend on a size of the pot recognized by the detection device and its alignment on the hob. The length extension of the geometric element preferably depends on the geometric dimensions of the pot recognized by the detection device, in particular its pot base size. Preferably, the length of the dividing line and the length of the transverse line correspond to the scale of the respective extension of the pot base. In the case of round pot bottoms, the dividing line and cross line are therefore the same length. Their length depends on the absolute diameter of the respective pots. The alignment of the geometric element preferably depends on the alignment of the pot on the hob. The display device is preferably designed to also display the geometric element with a corresponding angular orientation in the case of an angular orientation of a recognized pot on the hob. If the pot has a round or square pot bottom, a length extension of the transverse line in its direction of extension is preferably equal to a length extension of the dividing line in its direction of extension. If the pot has an elliptical or rectangular but not square pot bottom, a length extension of the transverse line in its direction of extension is preferably different from a length extension of the dividing line in its direction of extension. In a preferred embodiment, the dividing line and the transverse line cross each other on the display surface at a point which corresponds to a center point of the pot bottom of the pot positioned on the hob.

In a preferred embodiment, the display device is designed as a line type of the geometric element depending on an operating state of the heating unit (s) for heating the recognized pot and / or the occupied surface section (s) and / or a presence of the recognized pot on the surface section (s) to change. The line type can be, for example, a solid line, dashed line, dash-dot line, dash-two-dot line. For example, a solid line can signal that a pot has been recognized by the recognition device and the surface sections occupied by the pot are active. Furthermore, a dashed line can signal that a pot has been recognized by the recognition device but the surface sections occupied by the pot are inactive. A two-dot chain line can signal that a pot has been recognized by the recognition device, but that there is an error. As an alternative or in addition, different colored designs of the geometric element can also be used to indicate the operating state of the heating unit (s) for heating the recognized pot and / or the occupied area (s) and / or the presence or absence of the recognized pot on the area or sections that he occupied or has occupied. For example, a first colored configuration signals that the heating unit (s) and / or surface section (s) are in the on state, and a second colored configuration signals that the heating unit (s) and / or surface section (s) are in the off -Condition.

The display device is preferably designed to change a color design of each displayed operating parameter as a function of the adjustability of the operating parameter. For example, information about the operating parameters is shown with color semantics, in which a first colored configuration of the operating parameter signals that a hob operation is in focus, a second colored configuration of the operating parameter signals that a hob operation is not in focus, a third colored configuration of the The operating parameter signals that a hob function can be selected, a fourth color design of the operating parameter signals that a hob function cannot be selected, a fifth color design of the operating parameter signals that a hob value can be selected and a sixth color design of the operating parameter signals that a hob value is not available can be selected. The operating parameter can be represented in the form of one or more letters, numbers and / or symbols.

In a preferred embodiment, the display device is designed as a touchscreen. This gives the user the option of direct interaction with the operating parameters of each hotplate.

Preferably, the touchscreen is designed to move and / or allow to move the geometric element in at least one further area of the display surface, which is assigned to the surface section (s) of the hob, to the or to the displacement of the pot on the hob detected by the detection device which the pot has been moved. The geometric element can therefore move along on the display surface in accordance with the displacement of the pot on the hob. In a preferred embodiment, the cooking device is designed to automatically move the geometric element into at least one further area of the display surface in the event of a displacement of the pot on the hob detected by the detection device, the at least one further area being assigned to the surface section (s) that the moved pot occupies after it has been moved. In another preferred embodiment, the cooking device is designed with the geometric element in at least one further area of the display surface in the event of a displacement of the pot on the hob detected by the detection device to be moved by the user and / or to have the user confirm the displacement of the geometric element.

In a preferred embodiment, the cooking device has a memory which stores the operating parameters assigned to the geometric element, so that when the geometric element is shifted, the operating parameters assigned to the geometric element are shifted with the geometric element.

The touchscreen is preferably designed in such a way that a displayed length extension and / or alignment of the geometric element is and / or are adjustable. This allows the user to manually correct the geometric element if necessary. For example, the user can enlarge or reduce the dividing line and / or transverse line by means of zooming and thus also influence the size of the heated zone in relation to the bottom of the pot.

According to the invention, the touchscreen is designed in such a way that a displayed operating parameter can be adjusted by touch. For example, the display device is designed such that when the user touches the operating parameter, he provides a selection of adjustable parameters such as values or the like for touching. For example, the display device has a further display area on which the selection is made available after the user touches the operating parameter.

Fig. 1 shows a plan view of a cooking device according to the invention. The cooking device 1 comprises a hob 2, which is composed of several - purely by way of example forty-eight - surface sections 21. The cooking device 1 also has a heating device 3 with a plurality of heating units 31 for heating pots (not shown) which are positioned on the hob 2. Each heating unit 31 is assigned to a surface section 21. The heating units 31 are shown with hatched and dashed borders because they are actually not visible in the top view shown but are covered by the hob 2. The individual surface sections 21 are also shown in the plan view not visible to the user, he rather perceives the hob 2 visually as a homogeneous individual surface, ie the lines separating the surface sections 21 from one another are imaginary lines which the user does not see; therefore they are also shown in dashed lines. The cooking device 1 also has a detection device 4 for detecting the position of pots (not shown) on the hob 2 and for identifying one or more occupied surface sections 21 on which or on which pots (not shown) are positioned. The detection device 4 is also shown in dashed lines because it is actually not visible in the top view shown. The cooking device 1 also has a display device 6 for displaying an operating state of the occupied surface section (s) 21 and / or the associated heating unit (s) 31. The display device 6 has a display surface 61 which, in this embodiment, corresponds to a reduced-scale hob surface 211 of the hob 2. That is to say, the display device 6 has the same ratio of length and width dimensions as the hob 2. The display device 6 is also designed to display a pot (not shown) recognized by the recognition device 4 on the occupied surface section (s) 21 by means of at least one geometric element 62 in at least one area 611 of the display surface 61, which corresponds to the occupied surface section (s) 21 of the hob 2 is assigned. The individual areas 611 are not visible to the user when viewed from above, but rather he perceives the display device 6 visually as a single area, ie the lines separating the areas 611 are imaginary lines that the user does not see and are therefore again shown in dashed lines. The number of areas 611 corresponds to the number of surface sections 21; an area 611 is assigned to each surface section. In the in Fig. 1 The top view shown in the figure, no surface section 21 of the hob 2 is occupied by a pot so that the display device 6 does not display any geometric element.

Figs. 2 to 6 each show a top view of the in Fig. 1 Cooking device shown in operation. During operation in this context means that one or more surface sections 21 of the hob 2 are occupied by one or more pots. In the Figs. 2 to 6 the aforementioned imaginary lines of the display device 6 as well as the heating units 31 are omitted for the sake of clarity, while the imaginary lines of the hob 2 to show the surface sections 21 are shown as solid lines for the sake of clarity.

Fig. 2 shows a top view of the in Fig. 1 shown cooking device 1, in which a pot 5 is placed on the hob 2 by the user so that six surface sections 21 are occupied by him. The display device 6 is designed, the pot 5 recognized by the recognition device (not shown) on the occupied surface sections 21 by means of at least one geometric element 62 in areas (not shown) of the display surface 61 which are assigned to the occupied surface sections 21 of the hob 2. The geometric element 62 of the display device 6 is designed as a line element with a dividing line 621 and has subregions 623 on both sides of the dividing line 621. The line element also has a transverse line 622 which runs perpendicular to the dividing line 621, centrally through the dividing line 621 and thus defines further subregions 623 in the form of four quadrants. Overall, four subregions 623 are defined by the cross-like configuration of the line element. The display device 6 is designed to display a plurality of operating parameters (not shown) of the occupied surface sections 21 in the sub-areas 623 of the geometric element 62, which is not shown here for the sake of clarity but is shown in FIG Fig. 7 and 8a to 8e is explained in more detail.

Fig. 3 shows a top view of the in Fig. 2 shown cooking device 1, in which on the hob 2 by the user in addition to the in Fig. 2 Pot 5 shown, two further pots 5 are placed on further surface sections 21 of the hob 2, so that four further surface sections 21 are occupied by one further pot 5 with a round pot bottom and eight further surface sections 21 are occupied by the other further pot 5. The display device 6 is designed to display the pots 5 recognized by the recognition device (not shown) on the occupied surface sections 21 by means of at least one geometric element 62 in areas (not shown) of the display surface 61 that are assigned to the occupied surface sections 21 of the hob 2 . The three geometric elements 62 are each designed as a line element with a dividing line 621 and a transverse line 622 arranged at an angle to the dividing line 621 and have sub-areas 623 on both sides of the dividing line 621 and the transverse line 622, so that the cross-like design of each line element defines four sub-areas 623 are. The display device 6 is designed to display a plurality of operating parameters (not shown) of the occupied surface sections 21 in the sub-areas 623 of the geometric element 62, which is not shown here for the sake of clarity. A length extension and an alignment of the geometric element 62 depends on a size of the pot 5 recognized by the recognition device (not shown) and its alignment on the hob 2, as can be seen by comparing the three geometric elements 62 of the three pots 5. The geometric element 62 of the pot 5, which occupies the eight surface sections 21 and is inclined when viewed from above, has a different length and orientation than the geometric elements 62 of the two pots 5, which occupy four or six surface sections 21. In this way, the arrangement of the crosses on the display surface 61 represents an image of the real situation of the pots 5 on the hob 2 that can be intuitively recognized via the cross-pattern distribution and cross-pattern design.

Fig. 4 shows a top view of the in Fig. 3 Cooking device 1 shown, in which the user has removed the pot 5, which has occupied the eight surface sections 21, from the hob 2. The display device 6 is designed to change a line type of the geometric element 62 depending on the presence of the recognized pot 5 on the surface section or sections 21, so that the pot 5 removed from the hob 2 is displayed by the display device 6 in the form of dashed lines. As a result, an indication is visualized, for example, that the previously occupied surface sections 21 of the pot 5 that has since been removed can still be hot.

Fig. 5 shows a top view of the in Fig. 4 shown cooking device 1, in which the user the one pot 5, which in the plan view of Fig. 3 is arranged at the bottom right and occupies four surface sections 21, has shifted them to the top right on the hob so that the pot 5 occupies other surface sections 21 than in FIG Fig. 3 . The occupancy of the surface sections 21 of the pot 5 according to Fig. 3 is in Fig. 4 shown in dashed lines and the shift is shown by the arrow. The detection device 4 has recognized the displacement of the pot 5 on the hob 2 and has moved the geometric element 62 associated with this pot 5 into further areas (not shown) of the display surface 61 which are assigned to the surface sections 21 of the hob 2 to which the pot 5 has been moved. The display device 6 is designed to change a line type of the geometric element 62 depending on the presence of the detected pot 5 on the surface section or sections 21, so that the pot 5 moved on the hob 2 in the form of dashed lines from the display device 6 to the Areas (not shown) is displayed which are assigned to the surface sections 21 from which the pot 5 has been removed and is displayed in the form of solid lines by the display device 6 in the areas (not shown) which are assigned to the surface sections 21, the the pot 5 is occupied.

Fig. 6 shows a top view of the in Fig. 5 Cooking device 1 shown, in which the display device 6 shows the on the hob 2 according to the Fig. 3 and 4th displaced pot 5 in the areas (not shown) which are assigned to the surface sections 21 from which the pot 5 has been removed no longer indicates.

Fig. 7 FIG. 13 shows an enlarged plan view of a display device of FIG Fig. 2 shown cooking device. This in Fig. 2 The geometric element 62 of the display device 6 shown is designed as a line element with a dividing line 621 and a transverse line 622 running centrally perpendicular to the dividing line 621. The line element is thus designed as a cross and has four quadrant subregions 623 on both sides of the dividing line 621 and the transverse line 622. Overall, this cross-like configuration of the line element defines four subregions 623. The display device 6 is designed to display one operating parameter 63 in each of the four sub-areas 623 of the geometric element 62, the operating parameters 63 being shown here purely in sketch form.

Figures 8a to 8e each show an enlarged partial plan view of the in Fig. 7 display device shown, wherein Figures 8a to 8e each possible combinatorial configurations with regard to the display of the operating parameters of the in Fig. 7 represent the display device shown. Figures 8a to 8e each show the geometric element 62 with the dividing line 621 and the transverse line 622 running perpendicular to the transverse line and with the sub-areas 623 designed as four quadrants, with certain operating parameters 63 being displayed in the sub-areas 623. The assignment of the four quadrants 623 with assigned operating parameters can be fixed, but can also be designed to be variable and adaptable to user preferences. Various variations are described below purely by way of example. In preferred embodiments, the display surface 61 is designed as a touch-sensitive touch display. As a result, a user can select the operating parameters of a specific pot that he has selected by touching them and, in a further step, change them as required via an optically designed adjustability also visualized on the display.

Figure 8a shows as the displayed operating parameter 63 a power level of the heating units (not shown), which is assigned to the surface sections (not shown) occupied by the pot (not shown), in the form of a number and in the form of an on-off state of a warming function in the form of an icon.
