Embodiment Construction

[0071] figure 1 A domestic cooking appliance in the form of an oven 1 is shown. The oven 1 has a cooking space 2 which can be heated by means of at least one heating device 3 . The cooking product G can be brought into the cooking space 2 , where it is accommodated in a cooking utensil in the form of a bowl S. The bowl S is placed on the baking tray B.

[0072] Furthermore, the oven 1 has a plurality of light sources brought into the cooking space wall or behind the muffle 5 in the form of light-emitting diodes 6 producing a plurality of white lights, the light of which is passed through the muffle. At least one opening of 5 enters into said cooking space 2 . The at least one opening can be blocked by a viewing window (not shown).

[0073] Furthermore, the oven 1 has a light sensor in the form of a camera 7 brought into the lid of the muffle 5 . In this case, camera 7 is sensitive, for example, to the visible or “white” spectral range. In this case, the field of view F o...

Abstract

A method (S1-S9) is used for operating a cooking appliance (1), wherein at least one measurement profile (V0) for light reflected by a food (G) is recorded (S3-S6) during a heat treatment cycle, a time (tw) of a turning point is determined (S7) from at least one measurement profile (V0) and at least one action is triggered (S9) on the basis of the determined time (tw) of this turning point (S8). A cooking appliance (1) for performing the method (S1-S7) has, in particular: at least one light source (6) directed at the food (G), at least one light sensor (7) directed at the food (G), an evaluation device (8) for storing the at least one measurement profile (V0) and for determining the time (tw) of the turning point and a control device (8) for triggering the at least one action (S9) on the basis of the determined time (tw) of this turning point. The invention is more particularly advantageously applicable to ovens.

Description

technical field [0001] The invention relates to a method for operating a cooking appliance, in which at least one measurement curve of light reflected from food is recorded during a heat treatment process and the attainment of a target degree of browning is thereby determined. The invention also relates to a cooking appliance which is set up for carrying out the method. The invention can be applied particularly advantageously to ovens. Background technique [0002] The degree of browning of a food product can in principle be regarded as a subjective, taste-dependent variable for the consumer. This makes reproducible identification of the desired degree of browning difficult. [0003] The methods known to date for evaluating the baking and frying results are mainly based on a subjective evaluation of browning by means of an optical evaluation or on the basis of a color chart (eg NCS-color chart, according to the NCS- The color table compares luminance values ​​to a baselin...
