According to one aspect of the invention, it is proposed that the user interface comprises a means for selecting a dish to be cooked, in which the control unit is configured to determine at least one degree of heating of roast and / or fry recommended depending on the dish selected. Through the recommendation, also a user inexperienced can easily determine the degree of roast heating and / or correct frying, and a burning of the cooking product through a degree of roast heating and / or frying too high, or a unpleasant consistency that may be conditioned by a cooking temperature too low.

Temperature sensors in such fields of cooking, which directly measure the temperature of the piece of cooking battery, especially without contact by measurements optics of an infrared spectrum emitted by the piece of cooking battery, were used until now mainly in the industrial sector, where a rapid adjustment of the degree of roast and / or fry heating and specialized personnel Know the recommended settings. Therefore, it has resulted in technical prejudice that recommendations of the degree of warming of roasted and / or fried that necessarily need a selection complex of the dish or cooking product lead to complexity unwanted command process.

However, lately fields of cooking of this type with temperature regulating circuits of roasted closed increasingly also in the sector of household appliances, where no user can be expected relevant specialized knowledge. Simultaneously, it they use more prepared dishes, especially frozen dishes, which they can also be prepared without problems by inexperienced and amateur chefs. Therefore, more and more frequently Cooking fields with temperature sensors are used by inexperienced users, for whom a grade one recommendation heating roast and / or fry dependently on a Selected dish leads to a large increase in comfort.

In an improvement of the invention, proposes that the control unit be configured to display in the graphic display the degree of heating of roast and / or fry recommended. The user can then easily read the grade roast heating and / or frying recommended and adopt or Modify the recommendation.

If the control unit is configured to assume the degree of heating of roast and / or recommended frying for the activation of the heating zone, if the user does not select no other degree of warming can be simplified more handling, since after the selection of the dish you can Suppress other user interventions.

Similar advantages can be achieved if the control unit is configured to assume the degree of roast and / or fry heating recommended for operation of the heating zone, if the user makes adjustments of another heating zone or does not make any input for more time than a predetermined time interval.

The dish selection can be simplified if The medium for the selection of a dish to be cooked is configured for the representation of several groups of dishes with heating degrees of roasting and / or frying the same or similar in the user interface The dishes can be stored in a series of tree-type menus, being able to choose the user for example in a first step between non-frozen cooking products and frozen cooking products, in a second step between meat, fish and vegetables, and in a third step between dishes special.

The idea of the invention is usable in a manner especially advantageous in those cooking fields in which the temperature sensor is set as temperature sensor by infrared

The handling can be simplified further if the User interface is configured for the selection of three or four degrees of roasting and / or frying heating possible.

Likewise, the process of cooking if the control unit is set to determine a recommended cooking time depending on the dish selected.

It is also proposed that the control unit be configured for at least a second mode of operation enter by reading a direct adjustment of the degree of heating of roasting and / or frying of the user interface. The user experienced can use the second mode of operation and avoid a delay in the adjustment by selecting the dish.

If the control unit is configured to direct in at least one other mode of operation a power of heating for heating the heating zone of temperature dependent manner measured by the sensor temperature, the user can choose depending on the need between a regulated operation and an unregulated operation of the cooking field in the other mode of operation.

The user may slightly change the degree of roast heating and / or frying especially starting from grade roast heating and / or frying recommended if the interface of user understands means for increasing and decreasing the degree roast heating and / or frying.

An especially comfortable handling is attainable if the graphical user interface is configured as a screen tactile.

Another aspect of the invention relates to a procedure for operating a cooking field with at minus a heating zone, a temperature sensor for the determination of a temperature of a cooking battery piece arranged on the heating zone, a user interface with a graphic display and means for the introduction of a heating degree of roast and / or fry, and a control unit which is configured for at least one mode of operation regulate the temperature determined by the temperature sensor in a theoretical value depending on the degree of roast heating and / or tight frying.

To configure the procedure with greater ease of use, it is proposed that through the user interface select a dish to be cooked, and that the unit of command determine at least one degree of roast heating and / or recommended frying depending on the dish selected.

Figure 1 shows a cooking field with five heating zones 10, in each of which is arranged at least one temperature sensor 12 for the determination of a temperature of a cooking battery piece 14 arranged on the heating zone 10. Also, the field cooking has a user interface 16 with a display Figure 18 and means 20 for the introduction of a degree of roast heating and / or frying, and a control unit 22 that is set to regulate in at least one mode of operation, and in fact in a regulated roast operation, the temperature determined by the temperature sensor 12 in a theoretical value depending on the degree of roast heating and / or deep fried

Temperature sensor 12 is configured as thermal resistance and is arranged under the plate cover 24 of the cooking field, which is made of glass or ceramic hob In especially advantageous configurations, it they use two thermal resistances to be able to separate the radiant heat influences of the elements of heating the heating zones 10 of the heat which is transmitted by the cooking battery piece 14.

In alternative embodiments (no represented here), the temperature sensor 12 may be configured as infrared temperature sensor 12 and / or protrude from the cover plate 24, so that it can measure directly the infrared radiation emitted by a base of the cooking battery piece 14, and can detect so depending on the intensity of that one, and especially on its spectrum, according to Wien's law or Planck's radiation formula, the temperature of the base of the cooking battery piece 14. In comparison with temperature measurements with sensors temperature 12 that are arranged under the cover plate 24, through this you can achieve a measurement especially Accurate and more reliable.

User interface 16 is configured to the selection of three or four degrees of roast heating and / or Frying possible. A larger number would be thinkable, but according to the current state of the art would not provide any or, in any case, small advantages, in terms of the accuracy of the determination of the temperature, due to the inaccuracy of the temperature sensor 12.

The control unit 22 comprises a unit exciter not explicitly represented here for commissioning operation of the user interface 16, that is, for the activation of graphic display 18 and for introduction by User signal reading, which the user can activate by touching corresponding panels and / or keys of the user interface 16.

The user interface 16 further comprises a screen, that is, the display 18, and sensors arranged below of the display 18, sensitive to contact. The sensors of the contact sensitive user interface represented here only schematically they form a means of selection (figure 5) 20 for the selection of a dish to be cooked.

Figure 2 shows user interface 16 in A detailed representation. After connecting the cooking field by contacting the connection surface of on-off 32 of user interface 16, the welcome screen shown in figure 2 appears. The user can select one of the five heating zones 10 by gently touching one of the five connection panels 34a - 34e, to carry out adjustments for the actuation of the zone of heating 10 selected. In the embodiment example represented, the user selects the heating zone 10 bottom left by touching connection panel 34e.

After the selection of the heating zone 10, the representation of the screen shown in the Figure 3, in which the selected heating zone 10 is optically highlighted by a large increase. The expert too you can naturally choose other means to optically highlight the heating zone 10 selected. By driving band 30 or by contact of the increase key 26 or of the decrease key 28, the user can connect the zone of heating 10 selected in a normal operating mode and set a desired temperature or heating degree. Other connection surface 36 serves to connect a function enhancer (Booster function).

Alternatively to this, the user can select a first roasting sensor operating mode manual by touching a connection surface 38, and you can select a roasting sensor program operating mode by touching other connection surface 40. In manual operation mode of the roasting sensor, the user can choose using band 30 or by contacting the increment key 26 or the decrease 28 a desired broil level of three basic settings, which are then visualized by bars of different height in a schematic bar chart 42.

If the user selects a mode of Roasting sensor program operation by touching the other connection surface 40, the screen shown in the Figure 4, in which in a lower row the name of a dish to be cooked eligible. Through the operation of the increment key 26 or the decrease 28, the user can select another dish. Unit control 22 selects possible dishes from a list cyclic In figure 4, for example, vegetables are selected frozen, and in figure 5 cordon bleu.

The control unit 22 is configured by appropriate hardware and software to determine at least one grade roast heating and / or frying recommended for activation of the heating zone 10 selected or activated depending on the dish selected by the user with the medium 20. To do this, the control unit 22 represents in a circle representing the heating zone 10 selected a bar chart 42, which represents the degree of roast heating and / or recommended frying.

Bar chart 42 has three bars of different height, of which one is colored each time. The state with minimum heating power is represented by the smaller colored bar, the state with power of medium heating is represented by the medium bar colored, and the state with maximum heating power is represented by the largest colored bar. The diagram of bars 42 represents on each chosen plate a degree of roast heating and / or recommended frying, which the user still can be modified by actuating the band 30 or the keys 26, 28. For the dish chosen in Figure 4, the degree of roast heating and / or recommended frying is the degree of medium heating, and for the dish chosen in figure 5, the degree of heating of roast and / or recommended frying is the degree of maximum heating. On the screens represented in the Figures 4 and 5, the pan symbol 44 represents the mode of roasting operation, with which the area of lower left heating selected. Adjustment band 46 symbolized indicates that the degree of roast heating and / or Recommended frying can be modified by driving the band 30.

By recommending the degree of roast heating and / or frying which is shown by the command 22 on graphic display 18, also a user inexperienced can easily determine the degree of roast heating and / or correct frying and can prevent burning of the cooking product by a degree of heating roast and / or fried too high, or a consistency unpleasant that may be caused by a temperature of cooking too low.

If the user in a time interval default of approximately 3 seconds does not select any Another degree of heating, the control unit 22 assumes the degree roast heating and / or frying recommended for heating zone drive 10. The user can increase or decrease the degree of heating of roast and / or fry in operation at any time by contacting a increment key 26 or a decrease key 28. The increment 26 and decrease key 28 of the interface user 16 forms means 20 for increasing and decreasing the heating degree of roast and / or fry. User interface 16 further comprises a contact sensitive band 30. The unit of command 22 detects the place of a contact in one direction longitudinal of the band 30 and determines the degree of heating roasted and / or fried depending on the place of contact, if  The user wants to modify it. In another embodiment thinkable, the user can move their finger through the band 30, and the control unit 22 increases the degree of roast heating and / or frying or, in another mode of operation, a degree of regular heating, in an amount determined by the unit of control 22 in a manner dependent on movement parameters detected, especially the path length of the movement and / or a movement speed of the movement.

The control unit 22 assumes the degree of roast and / or fry heating recommended for operation of the heating zone 10 also if the user leads to make adjustments to another heating zone 10 and thereby indicate that I would not want to make any other adjustments in the area of heating 10 selected first.

Figure 6 shows a status screen that shows the display 18, if the user has not made any intervention for a few seconds. The symbol for the zone of heating down to the right indicates that the sensor mode of Roast is set to maximum temperature. The symbol for the zone heating up to the left carries the figure 8'5, which indicates that this heating zone is operated in a mode of normal operation in the heating degree 8'5. The scratched or color of the heating zone in the upper right indicates a residual heat from this heating zone.

Next to the connection surfaces already mentioned, the user interface 16 comprises in figure 2 also a timer key 46 for starting and setting a Timer function, a child safety key 48 for the configuration of a child insurance and an information key 50 for obtaining information and / or user settings of the field Cooking

Figure 7 shows another embodiment of the invention, in which the means 20 for the selection of a dish to be cooked includes a display 18 and is configured for the representation of several groups of dishes with heating degrees of roasting and / or frying the same or similar in the graphical user interface 16. Groups are represented each time in the form of a list. The user can change the lists represented by cursor keys, replace a member of the pre-selected group using other cursor keys, or confirm the selection of a group and / or a plate.

In another embodiment, the unit of knob 22 can be configured to determine not only the degree roast heating and / or recommended frying, but also a recommended cooking time, depending on the dish selected.
