Description

The invention relates to a hob.

In the kitchen of a private household and in the kitchen in the catering area are electric and / or gas hobs (also known as cooktops) known for preparation and heating of food. The hob generally includes a cooktop made of a glass-like or ceramic Material with separate cooking zones (hotplates) under which Heating devices such as radiant heaters, resistance heating elements, Induction heating elements are arranged or the gas burner exhibit. These hobs are usually in a kitchen worktop installed. The hob is common with a built-in oven generally below or built-in cooker combined.

DE 94 19 782 U1 discloses a cooktop with a glass ceramic cooktop with several cooktops, in which control elements and associated display elements for the cooktop are embodied in an edge region of the glass ceramic cooktop as infrared sensor-controlled contact surfaces. Associated controls for switching on and off, for setting the temperature and for setting a heating function of the hotplate are disclosed for each hotplate. In order to prevent cooking pots or frying pans from being placed on the operating and display elements, the area of the glass ceramic plate with the operating elements and the display elements is bent upwards as an inclined desk.

DE 30 10 714 A1 discloses an operating panel for programming four microcomputer-controlled, electrically heated hotplates of a glass ceramic hob. The control panel includes a pre-selection key for the pre-selection of the cooking time end and a pre-selection key for the pre-selection of the cooking time, four pre-selection keys for selecting the hotplate to be programmed, a four-row ten-digit pre-selection input keyboard for entering the times and the power levels, and a digital electronic display device for displaying the entered number Times. The preselection buttons are designed as sensor fields. To set the cooking time, a large number of control buttons are required with this control panel, which means a high cost and manufacturing effort. It is not described that the control panel is integrated in the hob.

The invention is based on the object, a special one Cooking appliance with a hob with an ergonomically adjustable Specify time control.

This object is achieved according to the invention with the features of claim 1.

a) ein Kochfeld (im allgemeinen plattenförmiger, horizontal verlaufender Kochfeldkörper), vorzugsweise aus Glas oder Glaskeramik, an dem (an der Oberseite) eine oder mehrere Kochstellen (Kochzonen, Aufstellflächen für Gargutbehälter) mit jeweils einer zugeordneten Heizeinrichtung ausgebildet sind, und

b) wenigstens eine Zeitsteuereinrichtung (Vorrichtung zur Zeitprogrammierung) zur Vorgabe (Voreinstellung) von Zeitdauer (Garzeitdauer) und/oder Startzeitpunkt (Garbeginn, Einschaltzeit) und/oder Endzeitpunkt (Garende, Abschaltzeit) für das Garen auf wenigstens einer der Kochstellen, also den Heizbetrieb der zugehörigen Heizeinrichtung, wobei die Zeitsteuereinrichtung wenigstens ein Betätigungselement zum Auswählen oder Einstellen der gewünschten Zeit (Zeitpunkt oder Zeitdauer) und wenigstens ein Anzeigeelement zum Anzeigen der über das wenigstens eine Betätigungselement vorgegebenen Zeit umfaßt.

The cooking device according to claim 1 comprises

a) a cooktop (generally plate-shaped, horizontally running cooktop body), preferably made of glass or glass ceramic, on which (on the top) one or more cooktops (cooking zones, support surfaces for food containers) are formed, each with an associated heating device, and

b) at least one time control device (device for time programming) for specifying (pre-setting) the time duration (cooking time duration) and / or start time (cooking start, switch-on time) and / or end time (end of cooking, switch-off time) for cooking on at least one of the hotplates, i.e. the heating operation of the associated heating device, the time control device comprising at least one actuating element for selecting or setting the desired time (point in time or duration) and at least one display element for displaying the time predefined via the at least one actuating element.

The at least one timing device is now on the hob arranged or, in other words, integrated with the hob, especially at the edge and / or below the Cooktop.

Timer") in das Kochfeld zu integrieren. Dadurch kann in ergonomischer Weise diese Kochstelle direkt am Kochfeld zeitprogrammiert werden und automatisch ohne ständige Überwachung des Kochendes betrieben werden. Ferner wird gemäß der Erfindung auch berücksichtigt, daß die Zeitsteuerung eine Funktion des Kochfeldes ist, die nicht während eines Garvorganges häufig geändert werden muß, anders als beispielsweise die Heizleistungssteuerung, und deshalb ein Zustellen des Bereiches des Kochfeldes mit der eingebauten Zeitsteuereinheit durch Gargutbehälter die Arbeitsabläufe beim Garen nicht negativ beeinflußt. The invention is therefore based on the consideration of a time control device for at least one hotplate (

Timer ") can be integrated into the hob. In this way, this hotplate can be programmed in an ergonomic manner directly on the hob and operated automatically without constant monitoring of the end of cooking. Furthermore, according to the invention, it is also taken into account that the time control is a function of the hob that is not frequently has to be changed during a cooking process, unlike, for example, the heating output control, and therefore a clogging of the area of the hob with the built-in time control unit by food containers does not adversely affect the work processes during cooking.

Advantageous refinements and developments of the subject the invention result from the dependent claims.

In an advantageous embodiment, each time control device below the hob (or one immediately arranged on the actual hob adjacent cover plate). Each actuator of the timing device is then actuated from the top of the hob and each Display element of the timing device from the top visible from the hob. Preferably, the timing device in one, preferably tub or box-shaped, Carrier device (hob holder, hob holder, Trough pan) held below the hob and by it carried.

In principle, it is of course also possible to use the time control device to attach to the underside of the hob, for example by gluing. By arranging the The timer remains below the hob Time control device for dirt and damage on the top of the hob serving as a work surface does not spare or hinder the handling of the Cooking pots or the food on the hob. The timing device can also be integrated in a hob frame his.

In general, the cooking device also includes an operating device for selecting and / or setting a heating intensity in each case for each of the heaters. The adjustable The heating intensity of the heating device determines the cooking intensity for the food to be cooked and in particular a heating output (continuous) or heating level (discrete) or one Hotplate temperature (regulated hotplate) or higher automated versions also in a cooking program fixed course of heating power over time or Hotplate temperature.

Through the integration proposed according to the invention for the first time the timing device in the hob now the problem that with self-sufficient cooktops, where too said control device for setting the cooking intensities must be integrated in the hob, a variety of Control elements in a clear and ergonomic way also on the narrowly limited free, i.e. not from hotplates occupied, surface of the hob in the standard installation dimension of 60 cm x 60 cm must be accommodated.

An advantageous development of the hob according to the invention is therefore based on further consideration, the operating device for setting the cooking intensity on the or the hotplates and the timing device for the Setting the switch-on period of the hotplate as separate and independently of one another (individually, one after the other in in any order) can be assembled and, if necessary, also form removable assembly units, for example by means of separate, separate circuit boards and electronic components mounted on it.

This makes small individual units for self-sufficient hobs formed, the simpler and with greater freedom of design on the hob, taking ergonomic considerations into account can be arranged.

Can also be used for hobs without time control as well for high-quality cooktops with time control, even for one different number of hotplates, the same operating device be used and any necessary Time control devices can be in the desired number and arrangement, offset on self-sufficient hobs (laterally to the hob) to the control device, added become.

The spatial separation of time control device and control device enables in a particularly advantageous embodiment the arrangement of the control device outside the hob (non-self-sufficient hobs). In order to can be used during cooking to regulate or control the cooking temperature operating device frequently required by an operator for the hotplates not through saucepans or frying pans be delivered or hinder their movement and / or be damaged by them. Preferably the control device for the hob on the control panel (Control panel, control panel, control panel) of a separate built-in control box or a cooking appliance (built-in cooker) that additionally includes a oven. Preferably on this control panel the control device for integrated the oven. On the control panel of the cooking appliance thus only the control units used regularly are arranged, while the less frequently used timing device for the hob removed from the control unit is integrated in the hob. This makes a clear Operation of the cooking appliance also with the additional function maintain the timing.

In a further embodiment, the time control device, and possibly also the control device, in one edged its own housing, which consists of a heat-insulating Material is used to protect sensitive electronic components. The control device is then outside the housing arranged the timing device.

The timing device and / or the operating device have in a further embodiment preferably optical, capacitive, inductive or piezoelectric sensors on the all a touch of a touch surface on the of the Able to detect top side facing away from the carrier device (so-called. Touch sensors).

The timing device generally also has a control unit on, preferably at least one microprocessor includes, for processing signals of each actuator and for driving each display element in dependence from the signals of the actuator or actuators, where all components are integrated together on a circuit board are.

To control the heating power of each heater, this Cooktop usually has a power control device, the one with the time control device and the control device is in operative connection. The power control device includes preferably one depending on operations of the operating device adjustable power actuator.

The timing device can now be integrated, depending from the time switchable switching element to Switching through or blocking the heating power for the heating device the hotplate, especially that of the power actuator specified heating power. This switching element for time control can now be used with electrical heating devices in particular an electronic switching element such as for example a semiconductor switch (semiconductor component with pass and blocking behavior, semiconductor valve) or a electromechanical switching element such as a switching relay and be a gas valve in the case of gas-operated heating devices, that opens or closes the gas flow to the hob. In this Version with switching element must be the time control device can not be fully electronic, but can also be electromechanical. In a second alternative is the power control device completely from the Time control device separately and only via control and / or Signal lines, in particular a data bus, connected to it. Here is the timing device in general fully electronic and controls one in the power control device existing switching element.

The time control device can also comprise a clock, so that also a time programming depending on their time is conceivable, especially when using a controllable Clock, for example a radio clock. The time of the clock can at least on the at least one display element being represented.

A particularly individually usable and adjustable hob results when the cooking time and / or the start time and / or the switch-off time can be specified for all hotplates.

Fig. 1 shows a section of a longitudinal section through a schematically illustrated hob 2. The hob 2 includes a cooktop 4, which is surrounded by a circumferential frame 6 is edged on its edge. The hob 4 can a glass ceramic, a glass or another at least in a sub-spectral range of the visible light spectrum translucent material be formed. The frame 6 can be made of stainless steel or a plastic. Below the hob 4 is a trough-shaped or box-shaped Carrier device (trough tray, trough box) 3 arranged. The carrier device 3 and the cooktop plate 4 are with one another at their edges, in particular over the frame 6 connected so that a structural unit is formed and the entire hob 2 with hob 4, frame 6 and Carrier device 3 can be transported and into a Kitchen worktop, not shown, can be installed. The carrier device 3 supports to be arranged under the hob plate 4 further components of the hob 2, in particular Heaters, one of which is an example Cooking area (cooking zone) 13 of the hob 4 arranged Radiant heater 8 is shown, and control and / or Control units.

In addition to the radiant heater 8, a time control device 12 for specifying a cooking time and start time and / or a cooking end time for the radiant heater 8 is mounted in the edge area of the carrier device 3 below the hob plate 4. The time control device 12 comprises a circuit board 9 which is held in an essentially closed housing 5 made of a temperature-resistant and good heat-insulating plastic (polymer material). The edges of the housing 5 lie on the underside of the hob plate 4, possibly with the aid of a seal or sealing compound, so that the circuit board 9 is largely protected all around from dirt and moisture. On the circuit board 9, on the top side facing the hob 4, there is an actuating element 7 with one or more touch sensors, in particular infrared sensors, capacitive sensors, inductive sensors or also piezoelectric sensors, a display element 11, in particular a light-emitting diode arrangement, liquid crystal display or vacuum fluorescence display, in particular in one Design as a seven-segment display or as a graphic (pixel-oriented) display, and a microprocessor 19 for monitoring and evaluating the signal output of the actuating element 7 and for controlling the display element 11 is electrically contacted. The actuating element 7 registers actuations for setting a cooking end time or a cooking duration in an opposite area on the upper side of the hob plate 4, which are indicated by an arrow pointing downwards. The display element 11 emits visible light upwards through the hob plate 4 and is controlled by the microprocessor 19 in such a way that the time just set with the actuating element is shown on the display element 11 for control by the operator. In particular, in one embodiment, an operator can actuate the actuating element 7 until the desired time appears on the display element 11, for example by providing + "and - Touch panels.

Furthermore, on the printed circuit board 9, for example on the latter Bottom, a switching element 17 is provided. The switching element 17 is via an electrical line (supply line, Power line) 10 with the radiant heater 8 and via another electrical line 10 'with one not Power supply part shown to supply the Radiant heater 8 connected to electrical heating power. The power supply part usually includes one Connection to a power network (mains connection) with an upstream Main switch and as a power control device for power or energy control for the radiant heater 8 an actuator, in particular a switching relay or a semiconductor control element, for setting the electrical Heating output or regulation of the electrical heating energy depending from one via one not shown in FIG. 1 Operating device selected cooking intensity (heat setting) in Simple control or temperature control. The switching element 17 of the time control device 12 creates an electrical connection between the two lines 10 and 10 'and thus between the Radiant heater 8 and the power supply part ago and conversely couples the radiant heater when switched off 8 from the power supply. If not activated Time control, the switching element 17 is always closed Status. If, however, a cooking end time or a Is set, the microprocessor 19 holds it Switching element 17 during the time until the set value is reached Boiling or at the end of the set cooking time in its switched-on state and then switches it on This time expires in the off state, causing the power supply of the radiant heater 8 interrupted becomes.

The timing control device 12 can deviate from the in Fig. 1 shown embodiment also no integrated Have switching element. In this case, the microprocessor 19 after the expiry of the time control, the actuator in the Power control device via signal lines, in particular a data bus.

Finally, the time control device 12 can also have one controlled by the microprocessor 19, not shown, acoustic signal generator, for example a small loudspeaker, have at the end of the set period of time or when the set end time is reached acoustic signal, for example a buzzer or a periodic Beep, generated.

In the excerpt shown in Fig. 2 on the schematic Hob 2 shown shows two hotplates 14, 16. Two further hotplates behind the hotplates 14, 16 are arranged, are in this drawing not visible. In the front left and the front right corner are two control fields in an actuation area 24 18 and 20 of a time control device 12 each two as touch elements (sensor buttons, touch fields) 28 trained controls for setting the time and in a display area 22 two each next to the controls arranged display elements 26 arranged. Each Control panel 18 and 20 is for timing two each of the four hotplates provided, each hotplate one Key element 28 associated with associated display element 22 is. The display elements 26 are with two 7-segment displays to display a two-digit minute number.

Pressing a button 28 for a desired hotplate from one arranged in the time control device 12 and logic module, not shown here, which in particular with a suitably programmed microprocessor can be realized, recorded and leads to the number of minutes starting at zero, increasing in order to specify a cooking time displayed for the hotplate in the display area 22 becomes. When you release the button 28 is for the hotplate the number of minutes currently displayed in the display area 22 specified as the cooking time. The 7-segment displays then show continuously of the display elements 26 the remaining Remaining cooking time. An early switch-off of the hotplate results either by pressing the button 28 to im Display area 22 for the number of minutes the value "zero" is displayed or by issuing one not shown here and toggle belonging to an operating device for specifying the heating output. This control device can especially in a separate control box in one Built-in furniture or on a control panel of a not shown Built-in cooker with an oven.

A glass ceramic hob modified compared to hob 2 30 with control fields 32 of a time control device 12 is schematically in Fig. 3 in a section of a supervision shown. The control fields 32 have according to FIG Display area 34 now has four 7-segment displays 26, so that the specification of a cooking time and a Cooking time in 24-hour format for each of the four hotplates is possible. For this purpose, the actuation area 35 of the Control element 32 via two touch elements designed as sensor keys, which are designed as plus button 36 and as minus button 38 are. You can do this by pressing the Plus and minus buttons 36 and 38 are selected on the one hand, whether the hour or minute number should be set and whether the cooking time or the cooking end time are specified should.

Between the two control fields 32 is approximately in the middle an operating device in front of the two hotplates 14 and 16 (Control panel) 31 arranged for setting the heating power the hotplates 14 and 16 and the other two rear Hotplates. The operating device 31 comprises in a left Area a plus sensor button 33 to increase the heating power and a minus sensor button 37 for reducing the heating power. With one in the right area of the control device 31 arranged keypad 39 with four similar to the arrangement of the hotplates can be arranged in a matrix Selected hotplate, its heating output set or should be changed. The currently set heating output is on a between the keypad 39 and the sensor buttons 33 and 37 arranged 7-segment display 41 is displayed.

Another compared to the embodiments according to the figures 2 and 3 alternative embodiment is shown in FIG. 4. In the excerpt from the supervision shown there a hob, in particular a glass ceramic hob, 40 four hotplates 42 to 48 recognizable, their heating power or Cooking intensity by means of an operating device 31, the again as can be constructed in Fig. 3 can be adjusted. In the middle of the hob 40 is a timing device 12 provided for setting the duration or end time of the Operation of the hotplate heaters. An actuation area 52 the timing control device 12 includes one in the drawing Representation of function key element arranged on the left side 54 and on the right side the one already known from FIG. 3 Plus button 36 and minus button 38. A display area 56 of the time control device 12 also has the arrangement of four 7-segment displays already known from FIG. 3 26 to represent a time in 24-hour format.

A signal field 58 is also included in the display area 56. In this signal field 58 there are four annular or circular disc-shaped ones Symbol areas 60, 62, 64 and 66 are provided, the Arrangement of the associated hotplates 42 to 48 is modeled. To display a currently adjustable, the selected hotplate can, for example, be the associated one Symbol range 60 to 66 flash; to represent a The corresponding pre-set hotplate can be used Symbol range 60 to 66 light up permanently. Likewise is a Color change to show the different operating states sensible. So it is the operator of the hob at all times allows you to recognize whether a hotplate is preset and if so, which hotplate (s) with regard to Preset cooking time and / or start or end time is. Within these annular symbol areas 60 to 66 can also be the heat content (hot or cold) of a worker Hotplate as well as after switching it off (residual heat indicator) are displayed.

The saving achieved in this time control device 12 of separate touch elements for each of the four hotplates 42 to 48 is achieved thanks to the function key element 54. The of the timing device 12 further included and not here The logic module shown further switches the function key element 54 automatically after a non-actuation period of for example 30 seconds in a first function "Hob selection". By pressing the plus button 36 or the minus key 38 flashes in the signal field 58 of the ring-shaped Symbol area of the last selected hotplate. With pressing the plus button 36 or the minus button again 38 becomes the next remaining position in the clockwise or counterclockwise direction selected.

If the desired hotplate is selected, is then after pressing the function key element 54 again, the function "Cooking time setting" possible. The cooking time (or Cooking end time) is then, as already explained for FIG the plus button 36 and the minus button 38 adjustable. With the pressing function button element 54 again closes the control panel is back and the operator is at again the function "hotplate selection". A non-actuation of the function key element 54 of more than 30 seconds also leads to this result.

In this way there is a time control for the entire hob 40 with only three pushbuttons (function pushbutton 54, Plus button 36 and minus button 38) with regard to cooking time or cooking end time of each of the hotplates 42 to 48 can be operated.

In the embodiments described in FIGS. 3 and 4 the entire hob 30 or 40 is also completely independent Can be operated from a built-in cooker or an external control box and can be arranged and thus designed as a self-sufficient hob.

The integration of the time control device is particularly advantageous in the hob but in the embodiments in which the control device for setting the hotplate heating intensities is not integrated in the hob (external Service).

Such an embodiment was already apparent from FIG. 2. 5 shows a further embodiment of this type Hob 2 with external control, but integrated Time control. The rectangular hob 2 is in a worktop 99 built into a fitted kitchen and from a frame 6 surrounded. Four are in the form of a matrix on the hob plate 4 arranged hotplates 72, 74, 76 and 78 marked, below which each have an associated heating device, not shown such as one or more radiant heaters are arranged. Hotplates 72, 74, 76 and 78 are assigned to one under the worktop 99 Control panel 80 arranged below the cooktop 2 Control knobs (rotary knobs, rotary knobs) 82, 84, 86 and 88 operable. By turning one of the control knobs 82, 84, 86 and 88, the heating output (heat setting, cooking intensity) the heating device of the associated hotplate 72, 74, 76 or 78 can be set. Behind the control panel 80 is one with the control knobs 82, 84, 86 and 88 mechanical connected and with the heating devices of the hotplates 72, 74, 76 and 78 electrically connected power control device provided that executed in a conventional manner can be. The set heating output can be printed on the control knobs 82, 84, 86 and 88 and / or the control panel 80 are displayed or on next to the Control knobs arranged, controllable optical display elements.

The spatial separation of hob 2 and control device with the control knobs 82, 84, 86 and 88 is advantageous because the control knobs 82, 84, 86 and 88 not the movement of the Food container on hob 2 is interfering. Instead of control knobs 82, 84, 86 and 88 can also be arranged on the control panel 80 Touch sensors are used. Here too these touch sensors on the oblique or vertical running control panel 80 not delivered by food containers are in contrast to the embodiments according to the 3 and 4, in which this is a certain disadvantage.

It is now in hob 2 in a front right here, Corner area a time control device 12 for the hotplate 78 integrated with arranged below the hob 4 Actuators 45 and 47 and indicators 43, the each operable from the surface of the hob 2 or are visible. Delivering the control surface to this Time control device 12 by food containers during a Cooking process is not problematic because of the time control is set only once and then runs automatically.

It can, of course, also in the exemplary embodiment according to FIG. 5 a differently designed and / or for several hotplates provided time control device 12, in particular in a Execution according to one of FIGS. 1 to 4, may be provided.

Below the control panel 80 is a cooking oven (built-in oven) 1 arranged with a lockable by a door 92 Cooking space 95. In the door 92 there is a viewing window 94 for viewing formed in the cooking space 95. Are on the control panel 80 now in addition to the control knobs 82 to 88 for hob 2 further control knobs 83 and 85, especially for heating selection and for temperature selection, and a display 87 for the Cooking oven 1 provided.

All frequently used controls (and associated displays) to operate the hob 2 and oven 1 Combined cooking appliance (built-in cooker) are thus on the control panel 80 ergonomically summarized, while the usually much less frequently used timing device 12 is integrated in the hob 2 and thereby the No clarity of operation on the control panel 80 impaired.
