User recognition can be performed by any technical means,
which make it possible
the user at the cooking appliance
to identify. On the one hand, it is conceivable for the user to
as a person, to recognize, for example, by name. alternative
It is conceivable that the identification only up to one user group
goes into detail, so for example a group of trained
technical realization of a user recognition is a
USB stick reader on the cooking appliance
provided. The user guides

Also a file stored on the USB stick can be executed

advantageous because there by means of the stored data, the control panel
can be. For example, a record of personal
Settings are read from a file and the cooking appliance afterwards
be set. These settings can affect both the cooking process
as well as the operating process of the device.

User recognition can also be over

With. Both active and passive RFID chips are available to the user
both read-only RFID chips and readable and writable chips
Another technical realization option can be seen in a chip card reader. Smart cards, often called smart cards, are known from numerous technical fields and can also be both read out and described. An advantage of smart cards is that they can be adapted in format to the often used credit card size and, for example, can carry a photo of the user, so that the cards can serve not only for identification by a cooking appliance, but also for identification for a menu without the use of additional readers.
the technical realization of the user recognition lies in the
Entering a code on the cooking appliance.
Biometric recognition can be used, for example via a
Fingerprint sensor, a camera for detecting the iris, the face,
the whole person, the retina, etc., or a microphone for the voice.
Microphone can also log in to the device via voice recognition or
Speech recognition done, for example, the pronounced name
and / or a password.
a purely optical recognizer is conceivable, for example via a
Barcode reader. A barcode reader can be fast and reliable
Read barcodes from plastic cards or cardboard signs.
technically further realization of a user identification is
in a detection for a

further, technically quite simple implementation of a user recognition
provides that on the cooking appliance

if several cooking appliances

an activation device is provided for the user recognition,
in particular in the form of a motion detector and / or a timer.
For example, in the case of an RFID sensor this only then
scan the environment for RFID chips when a motion detector is detected
indicates that there is a person in front of him. This can
to be extended so that the user recognition only then
is activated when the person has a certain amount of time, for example
two or three seconds, before the cooking device lingers. With such
Activation can be largely ruled out that a passing on the cooking appliance

the individual setting has a language setting. One
Users can get started with such functionality immediately
in a for
Language, preferably in his native language, on the cooking appliance.
Also, the individual setting may have a noise setting. So it is conceivable that a user specifies certain acoustic signals, regardless of the acoustic signals of other users. It is conceivable that a user who uses several cooking appliances simultaneously with other users adjusts the same acoustic signal on each cooking appliance, so that it is already clearly identifiable by the acoustic signal to which operator this acoustic signal is directed. Even if the user is currently not on the acoustically-signaling cooking appliance, he will even realize that the cooking program set in motion has now expired, for example, and he will go to the signaling cooking appliance.
individual adjustment may also have a number of trays.
This can be used, for example, for a specific

that the individual setting is a user interface for a display
