  • the cleaning device comprises a device for, preferably metered, donations of at least one detergent, rinse aid and / or descaling agent.
  • the measuring device is suitable for detecting the level of the Beschwadungs worn the steam generating device, the cooling device and / or the dispensing device of the cleaning device, preferably via at least one level sensor and / or weight sensor.
  • the present invention is based on the knowledge that desired cooking results can be reproducibly ensured by completely inexperienced operators of a cooking appliance only if the operators only have to bring food into the cooking appliance and then the cooking process, especially after switching on the cooking appliance and closing the oven door , is done completely automatically.
  • the invention is based on the finding that a desired cooking chamber cleaning of completely inexperienced operators of a cooking appliance can only be ensured if the operator has to refill detergents only on request of the cooking appliance.
  • FIG. 1 thus shows a cooking appliance 1 with a cooking chamber door 2, which comprises only a single actuating element in the form of an on / off switch 3.
  • An operator of the cooking appliance 1 according to the invention must only open the cooking chamber door 2 for introducing not shown Gargut in a cooking chamber, not shown, place the food in the oven, close the Garrraumt 2 and turn on the cooking appliance 1 via the on / off switch 3.
  • a control device in operative connection with a measuring device (not shown) and a storage device (not shown)
  • a heater (not shown) and / or a steam generating device is operated to automatically perform a cooking process.
  • the food is automatically detected, so that then the cooking process either as a function of preset parameters or stored in a storage device of the control Garprofilen can be performed.

  • the cooking appliance 1 'of the embodiment according to Figure 2 differs from the Gareredaus arrangement 1 according to Figure 1 in particular in that no actuator is provided and instead of a cooking chamber door 2, an air curtain 2' is provided. More specifically, in a cooking chamber 10 'an air guide member 11' for separating a fan chamber 12 'is arranged, in which an impeller 13' and wound around this Bankwarel 14 'are arranged, the impeller 13' air also targeted to a plurality of parallel air nozzles 15 'leads, which in each case an air intake opening 16' is opposite, so that between the air nozzles 15 and the air intake openings 16 optionally an air curtain 2 'for closing the cooking chamber 10' can be generated.
  • an infrared sensor 17' is also arranged, via which the arrangement of a food (not shown) in the cooking chamber 10 ', even the position of such a food in the cooking chamber 10', can be detected, such as in the context of DE 10 2005 046 716.4 described in order immediately after detection of a food in the cooking chamber 10 'automatically close the same about the air curtain 2' and initiate a cooking process in which the food to be cooked with heat and / or steam is acted upon, again on the basis of a cluster process according to WO 2004/62372 A2.
  • a cooking process sensor 17 " can also be used in a further cooking appliance according to the invention (not shown) both for detecting a food 5" in a cooking space and for detecting specific quantities of food to be cooked 5 " the cooking process sensor 17 "the arrangement of a food 5", in which it is at least partially introduced, has been detected in the oven, for example on the basis of the disclosure of DE 100 61 821 C2, a cooking process is automatically started an actuator as part of a Switching device is thus not necessary. Rather, a switching device is provided by the cooking process sensor 17 ". In addition, the cooking process is automatically guided by means of the cooking process sensor 17 ", as described, for example, in DE 199 45 021.
  • a regulating device 20 which receives and evaluates the output data of the cooking process sensor 17" is entered Steam generator 21 ", an impeller 23", a heater 24 "and a display device 25" driven.
  • the food to be cooked 5 can thus be specifically subjected to heat and / or steam.
  • a cleaning process can be initiated automatically, namely as soon as it has been detected via the cooking process sensor 17 "that no food item 5" is arranged in the cooking space.
  • a cleaning device 22 is specifically actuated via the regulating device 20 'Both during the cooking process and during the cleaning process, the respective stage of the process can be displayed via the display device 25", including the detected type of cooking product or the degree of soiling.
  • the display device 25 but can also be communicated to an operator automatically, whether water, detergent or the like can be refilled.
