The invention relates to a cooking appliance, in particular a commercial
Combi steamer, especially for fully automatic
Cooking of food.
so also commercial cooking appliances, are in the state of the art
On the one hand is in the WO 2004/062372 A2
described that, with the help of a cluster analysis, cooking processes can be compacted, typed, profiled and mathematically clearly characterized and described despite their highly complex contexts, so that the running of a cooking process can be reduced to a few key variables to be defined. On the other hand it is from the EP 1 022 972 B1
It is known that by taking into account the temporal behavior of measured variables which relate to changing properties of the food during a cooking process, the quantity and in particular the thickness of a food can be taken into account in the guidance of a cooking process without being directly measured or entered into the cooking appliance Need to become.
Steps have already been taken to automate a cleaning process, such as in the DE 199 61 835 C2
described. Thereafter, from a cooking space effluent effluent water is at least partially reused and a cleaning cycle automatically controlled by a special sensor.
Special measuring devices that automate a cooking process have also been developed. So it is for example from the DE 199 45 021 A1
Known via a Garprozessfühler, which is at least partially inserted into a food, at least to determine a specific Gargut- and / or cooking appliance size for Garprozesssteuerung. As Gargutgröße are there explicitly the core temperature of the food, the placement of the Garprozessfühlers in the food, the diameter of the food, the density of the food, the Gargutart, the degree of ripeness of the food, the pH value of the food, the consistency of the food, the storage state of the Garguts, the smell of the food, the taste of the food, the quality of the food, the browning of the food, the crusting of the food, the vitamin degradation of the food, the formation of carcinogenic substances in the food, the hygiene of the food and / or the thermal conductivity of the food described. How can one recognize whether such a Garprozessfühler is actually placed in a cooking product, so that only when detected lancing the Garprozessfühlers a normal operation of a cooking process is continued, with the adjustment of a possible Fehlstechung, is for example in the DE 100 61 821 C2
described. A method for detecting improper application of a Garprozessfülhlers is also from the DE 102 11 643 A1
known. Furthermore, under the WO 2004/109246 A1
describes how, in particular, the thermal conductivity and / or the specific thermal conductivity of a cooking product can be detected via a cooking process sensor. The DE 101 09 246 C1
also teaches how the color inside a food can be detected by detecting electromagnetic radiation and used for cooking process control. In the DE 101 09 252 C2
is still the evaluation of sound waves in a food to be described in particular for determining the consistency of the same, which can also be used for Garprozesssteuerung.
Alternatively or in addition to Garprozessfühlern that are stabbing into a cooking appliance, a variety of other measuring devices in the art for detecting specific Gargutgrößen is also known. For example, the DE 101 14 080 C1
the detection of the pH value, the electrical conductivity, the optical behavior, the spectroscopic behavior, the odor and / or the behavior upon the action of enzymes of organic liquid substances emerging from a food during cooking for controlling a cooking process and / or cleaning process , In the DE 10 2004 062 737.1-34
is a sniffer sensor for detecting the atmosphere, for example, the Garinnenraums known, depending on the output values controls a control system cooking processes. In the DE 10 2005 046 716.4
is described as an infrared measuring device, the position of a food in a cooking chamber for selectively applying the same with heat, cold, steam, a gas, a liquid, a solid, electromagnetic radiation, an electric field and / or a magnetic field for the purpose of automating a cooking process is detectable.
In the case of automation of a cooking process, the detection of the installation site and / or installation height of the cooking appliance is used to set predetermined cooking programs and internal parameters, as in the context of DE 103 01 526 B3
Furthermore, it can be useful for automating cooking processes in cooking appliances whose cooking chamber is closable with a cooking chamber door, to automatically consider the opening degree of the cooking chamber door and the duration of the opening of the cooking process, as in the context of DE 10 2005 020 744.8
An automation of a cooking process or cleaning process should also be realized with energy savings, in particular here special is to refer to storage facilities, as for example. In the EP 1 092 115 B1
Finally, the shows EP 1 666 798 A2
a cooking appliance, which performs a fully automatic cooking process, wherein on an operating front of the device only either an on-off switch or no control element is present.
The WO 2008/088124 A1
proposes a cooking appliance in which the user is identified via an RFID tag.
The present invention is based on the object, an improved
Cooking device to provide.
A first aspect of the invention solves this problem
Cooking appliance, in particular for fully automatic cooking of
Food to be cooked, with one front panel, with exactly one emergency stop button on the front
is arranged, and no switch or another button.
The invention is based on the recognition that the existing measurement
Although control technology is capable of a cooking process fully automatically
but that is a better solution
gives as either no control at all or just an on-off switch
provided. This better solution lies in exactly one emergency stop button.
Button of the type proposed here differs from one
On-off switch by allowing only operability,
which causes an immediate shutdown of the cooking appliance.
The solution proposed here is therefore on the one hand opposite
the variant with the on-off switch advantageous because the power
is transferred to the automatic sensor of the device,
so that no operator errors can occur. on the other hand
is the solution proposed here compared to the
Variant with a control panel completely without controls
advantageous because an emergency stop button a much higher
technical safety in operation guaranteed.
is a standby mode via a proximity detector
activatable, in particular via a motion detector or
an RFID sensor. A cooking appliance, which this aspect
has at least two modes, namely
on the one hand a standby mode and on the other hand a standby mode.
In standby mode are those sensors of the cooking appliance
activated, which are required to automatically initiate the cooking process.
Since the cooking appliance has no on-switch on the
Front panel are in any case sensors for initiating
the cooking process available. These sensors consume energy
even if it is just a monitoring electronics
for a door contact switch. In the introduction to the description
was a non-exhaustive overview of various

the operator only in front of the cooking chamber door of the cooking appliance
needs to go, whereupon the proximity sensor detects that
someone stands there, whereupon the cooking appliance lights
turns on in the oven. Oven doors usually have a viewing window,
so that the operator takes a look whenever she wishes
can throw on the food, but this is very energy efficient

was already mentioned that the person detection sensor
is preferably activated during a cooking process.
Alternatively, it is conceivable that the person detection sensor in
a stand-by mode is activated.
a third aspect of the invention solves the problem
a cooking appliance, in particular in an embodiment as above
described, with additional, other sensors, in particular all
Sensors, then turned on, especially only then turned on

the cooking appliance is detected.
Aspect has already been mentioned. If no person before the
Gargerät is detected, at least one sensor should be active,
namely the person detection sensor, the room
monitor for an operator in front of the cooking appliance
should. This is preferably a pure motion sensor and / or a
RFID sensor. A heat sensor is also conceivable
in a kitchen, however, mostly with the danger

understands that the most energy-efficient programming provides
that without present operator only the person detection sensor
is active, wherein upon entering the operator in the detection area
the remaining, other sensors are activated.
also good variant provides that when entering the operator
in the detection area only the light and a door contact sensor
to be activated. By opening the cooking chamber door
the remaining, other sensors are activated.
The invention will be explained in more detail below with reference to an exemplary embodiment:
A commercial cooking appliance in the form of a combi steamer is used in a catering business to have various cooking products prepared by untrained personnel.
Cooking device has various connections,
especially for gas, water, electrical energy and wastewater.
an operating front of the cooking appliance are a cooking chamber door
with a handle and an emergency stop button. Other controls are located
not on the front of the cooking appliance. Also the side walls
and the rear wall of the cooking appliance are free of controls.
A main switch is located inside the cooking appliance
for maintenance purposes.
To cook a food, the operator uses the food either directly or with packaging or food support. She goes with the food in front of the cooking appliance. There she is from a Be detected motion detector of the cooking appliance. The cooking appliance is in stand-by mode until then.
Control electronics in the cooking appliance detects by
the feedback from the active motion detector that is
