Embodiment Construction

[0030] Subsequently, the invention is explained in more detail by way of example with regard to the application of (induction) cooktops, without the invention being restricted to use in such domestic cooking appliances or in general domestic cooking appliances.

[0031] The hob 10 has a plurality (four in the exemplary embodiment) of heating zones 12 , an operating device 14 and a hob controller (apparatus controller in the context of the invention) 16 . The hob controller 16 is connected to the operating device 14 and the heating zones 12 and controls the operation of these heating zones according to the user's settings via the operating device 14 .

[0032] as in figure 1 As outlined in , the hob 10 also has at least one sensor 18 for detecting noises that are being heated (heated, cooked, etc.) ) due to the formation and collapse of air bubbles. By way of example, the sensor 18 is arranged below the glass-ceramic plate of the hob 10 in the middle region between the four h...

Abstract

A boiling state of a liquid can be detected during a process of heating the liquid in a heating zone (12), for example of a cooking appliance (10): a sensor (18) senses noise caused during the heatingof the liquid in the form of a measuring signal (A), an analytical unit (20) converts a time diagram (B) of the sensed measuring signal (A) into a frequency spectrum (D) and then determines the boiling state of the liquid by using an intelligent algorithm (E) on the basis of the frequency spectrum (D).

Description

technical field [0001] The invention relates to a method and a device for detecting the boiling state of a liquid during a heating process in a heating zone, in particular a liquid in a cooker in a heating zone of a domestic cooking appliance. Background technique [0002] In the case of conventional domestic cooking appliances, in particular hobs, the user must personally monitor the heating and cooking process of the food in the cooking utensil on the heating zone of the appliance and manually terminate or adjust the cooking process if necessary. Heating process. In order to improve user safety and operating comfort, there is a need for automatic monitoring and, if necessary, adjustment of the heating process. For this purpose, the boiling state of the liquid in the cooking appliance must be able to be recognized automatically. Different methods are known for determining the temperature of a cooker or its contents, but no reliable method is known for identifying the boil...
