Description

Die Erfindung betrifft eine Kochmulde mit den Merkmalen des Oberbegriffs des Anspruches 1. Eine solche kochmulde ist aus DE-A-4 336 752 bekannt.The invention relates to a hob with the features of Preamble of claim 1. Such a hob is known from DE-A-4 336 752.

Bei Kochmulden ist es bekannt, die Heizleistung des Heizkörpers für eine Kochplatte manuell, z.B. mit Hilfe von Knebeln, an unterschiedlich gewünschte bzw. erforderliche Garkenngrößen anzupassen. Bei den Garkenngrößen handelt es sich z.B. um unterschiedliche Garungsarten (Wärmen, Kochen, Braten, Dünsten etc.) oder um unterschiedliche Garungsintensitäten (schwaches Kochen, starkes Kochen etc.). Nachteilig bei den vorbekannten Kochmulden ist es, daß deren Bedienungselemente nur eine ungenügende Anpassung der Heizleistung an unterschiedliche Garkenngrößen ermöglichen. Im einfachsten Fall erlauben die vorbekannten Bedienungselemente lediglich die Auswahl einer bestimmten Leistungsstufe (z.B. 1-3, 1-9). Eine Verminderung der Heizleistungszufuhr findet nicht statt. Ein Anwender muß deshalb den Garvorgang ständig überwachen. Komfortablere Bedienungselemente gestatten zeitgesteuerte Ankoch- bzw. Anbratphasen eines Garvorganges. Unabhängig davon, ob das Gargut in dieser ersten Phase des Garvorgangens kocht oder nicht kocht, wird bei diesem System die Leistungszufuhr nach einer fest eingestellten Zeitdauer vermindert. Der Anwender muß deshalb wiederum umständlich den ordnungsgemäßen Ablauf des Garvorganges überwachen.In cooking hobs, it is known the heating power of the radiator for a hotplate manually, e.g. with the help of gags, to different desired or required cooking parameters adapt. The cooking parameters are e.g. around different types of cooking (heating, cooking, roasting, steaming etc.) or different cooking intensities (weak cooking, strong cooking etc.). A disadvantage of the Known hobs is that their controls only insufficient adjustment of the heating output to different ones Enable cooking parameters. In the simplest case the known controls only allow Selection of a certain performance level (e.g. 1-3, 1-9). A There is no reduction in the heating power supply. On The user must therefore constantly monitor the cooking process. More comfortable Control elements allow time-controlled parboiling or searing phases of a cooking process. Independently of, whether the food is cooking in this first phase of the cooking process or not boiling, this system uses power decreased after a fixed period of time. The user must therefore be cumbersome the proper Monitor the progress of the cooking process.

Der Erfindung liegt die Aufgabe zugrunde, eine Kochmulde der eingangs näher genannten Art bedienungsfreundlich zu gestalten. Diese Aufgabe wird durch die Merkmalskombination des Anspruches 1 gelöst.The invention has for its object a hob user-friendly design mentioned in the beginning. This task is achieved through the combination of features of the claim 1 solved.

Zu diesem Zweck ist an der Kochmulde ein Bedienfeld angeordnet. Durch Betätigung des Bedienfeldes wählt der Anwender eine erste Garkenngröße, z.B. "Kochen", aus. Das Bedienfeld ist mit einer die Temperatur der Kochplatte überwachenden und den Heizkörper zur Temperaturregelung der Kochplatte ansteuernden Regel- oder Steuereinrichtung gekoppelt, so daß die Regel- oder Steuereinrichtung die ausgewählte Garkenngröße als Signal empfängt. Da jeder Garkenngröße gleichzeitig eine vorbestimmte Temperatur oder ein vorbestimmter Temperaturbereich für die Kochplatte zugeordnet ist, erreicht der Anwender das Ziel der ausgewählten Garkenngröße ohne weitere Überprüfungen des Gargutes oder manuelle Regelungen der Heizleistung. Da die Regel- oder Steuereinrichtung die aktuelle Kochplatten-Temperatur ständig mit dem der Garkenngröße entsprechenden Temperaturbereich oder Temperatur vergleicht, wird mit der erfindungsgemäßen Kochmulde der gesamte Garvorgang oder eine einzelne Garphase allein durch eine Elektronik der Regel- oder Steuereinrichtung automatisch abgeschlossen.According to the invention, the cooking process is monitored redundant for the user. In the hob according to the invention the cooking process is regulated automatically. This enables one Comfortable operation of the hob simply by choosing one certain cooking parameters, e.g. a certain type of cooking. For this purpose, a control panel is arranged on the hob. The user selects by pressing the control panel a first cooking parameter, e.g. "Cooking" from. The control panel is used to monitor the temperature of the hotplate and the radiator for temperature control of the hotplate controlling regulating or control device coupled so that the regulating or control device the selected cooking parameter received as a signal. Because every cooking parameter at the same time a predetermined temperature or a predetermined temperature range assigned to the hotplate, the User the target of the selected cooking parameter without further Checking the food to be cooked or manual regulation of the heating output. Because the regulating or control device is the current one Hotplate temperature constantly with that of the cooking size Compares temperature range or temperature, the entire cooking process with the hob according to the invention or a single cooking phase using electronics alone the regulating or control device is automatically completed.

Die automatische Regelung des Garvorganges kann erfindungsgemäß weiter vereinfacht werden, indem einer manuell ausgewählten Garkenngröße eine zusätzliche Garkenngröße, z.B. auch die Gardauer zugeordnet wird. Auf diese Weise lassen sich unsinnige Kombinationen mehrerer nacheinander ausgewählter Garkenngrößen vermeiden. Außerdem lassen sich innerhalb eines Garvorganges mehrere Garphasen zeitlich verbessert aufeinander abstimmen. Der gesamte Garvorgang ist dadurch zeitlich und auch hinsichtlich des Energieverbrauchs optimiert. Zudem ermöglicht dies auch eine verbesserte Qualität des Gargutes selbst.The automatic control of the cooking process can be according to the invention can be further simplified by having one manually selected Cooking parameter an additional cooking parameter, e.g. also the Cooking time is assigned. This way you can make nonsense Combinations of several successively selected cooking parameters avoid. In addition, within one Cooking process several cooking phases improved in time with each other vote. The entire cooking process is therefore timed and also optimized in terms of energy consumption. moreover this also enables an improved quality of the food self.

In the control panel is a designation corresponding to the food, in particular the name of the food to be cooked and the type of cooking entered, e.g. e.g. "Vegetables" and "Cooking". The correspondingly predetermined one Cooking intensity is in the regulating or control device saved and the selected cooking parameters automatically assigned, making the cooking process fully automatic is regulated.

Anspruch 3 betrifft eine weitere Maßnahme zur Vereinfachung der automatischen Regelung des Garvorganges. Als Garkenngröße wird lediglich die Bezeichnung des Gargutes, z.B. "Milchreis", in das Bedienfeld eingegeben. Die Auswahl weiterer Garkenngrößen durch den Anwender ist überflüssig, da der ausgewählten Bezeichnung bereits eine vorbestimmte Garungsart, Garungsintensität und gegebenenfalls Gardauer als zusätzliche Garkenngrößen in der Regel- oder Steuereinrichtung abgespeichert und der ausgewählten Garkenngröße zugeordnet sind. Deshalb erfolgt nach Eingabe der Bezeichnung des Gargutes wiederum eine vollautomatische Regelung des gesamten Garvorganges.Claim 3 relates to a further measure for simplification automatic control of the cooking process. As a cooking parameter only the name of the food to be cooked, e.g. "Rice pudding" entered in the control panel. The selection of others Cooking parameters by the user are superfluous because the selected name already a predetermined type of cooking, Cooking intensity and, if necessary, cooking time as an additional Cooking parameters in the regulating or control device saved and assigned to the selected cooking parameter are. Therefore, after entering the name of the food to be cooked again a fully automatic control of the entire cooking process.
