Definitions

  • the invention relates to a cooking appliance system according to patent claim 1 and a method for operating the cooking appliance system according to patent claim 14.
  • Various kitchen appliances which can also be referred to as cooking appliances, are known for the preparation of foodstuffs, which can also be referred to as items to be treated or as items to be cooked.
  • These include the hobs on which the food can be cooked in a cookware such as in a saucepan, with or without a lid, in a pan and the like by boiling, roasting and the like.
  • the cooking utensil is placed on a hotplate of the hob and the bottom of the cooking vessel is heated electrically, inductively and the like by the hotplate.
  • the cooking utensil can also be referred to as a cooking vessel, a support for the food to be cooked or a receptacle for the food to be cooked.
  • the cooking utensil provides a cooking space for the food to be cooked, which in the case of pans and pots can be open or closed by means of a lid.
  • Cooking appliances are also known which have a cooking chamber which is formed immovably, i.e. fixedly, with the cooking appliance and in which the food to be cooked can be arranged in or on a cooking utensil and cooked with the cooking chamber of the cooking appliance closed.
  • a cooking appliance can be, for example, an oven, a steamer, a microwave, a combination oven with a steamer and/or with a microwave, and the like.
  • Such cooking appliances with a fixed cooking chamber usually have a height of about 45 cm in the vertical direction, at least in Germany, with ovens also having a height of about 60 cm being common.
  • Such cooking appliances with a fixed cooking chamber have in common that they have an outer housing as the outer housing, which essentially encloses the cooking appliance on the outside and protects its individual components and elements and makes them manageable together.
  • An interior space is formed inside the cooking appliance, which represents the cooking chamber and is essentially enclosed by an inner housing as the inner housing, also known as the cooking chamber muffle or muffle.
  • a housing space is formed as an intermediate space between the inner housing and the outer housing, in which functional elements of the cooking appliance such as a controller or a control unit, an electrical power supply and other components can be arranged which serve the intended use of the cooking appliance.
  • the outer housing, the inner housing and a panel or a front panel together close the housing space, so that the housing space is not accessible to the user.
  • the interior of the cooking appliance has a through opening as an access opening at a depth to the front, through which the interior of the cooking appliance is accessible to the user, in order to insert cooking utensils into the interior of the cooking appliance as its cooking chamber and to arrange them there, and to remove cooking utensils after the treatment of the Remove food from the interior of the cooking appliance and remove it from there.
  • the access opening can be opened by the user by means of a closure element, for example in the form of a laterally pivoting door, a downwardly pivoting flap and the like, in order to be able to access the interior of the cooking appliance, as described above, or to close the interior of the cooking appliance and to carry out the cooking process or the cooking process.
  • a closure element can be closed or have a viewing window to allow the user to look into the closed interior of the cooking appliance.
  • Such cooking appliances with a fixed cooking chamber are usually designed as built-in appliances or as kitchen built-in appliances in order to be arranged in a space-saving manner and at a height that is easily accessible to the user in the vertical direction in kitchen furniture, such as in built-in cupboards in a kitchen, with their outer housing and with their locking element , If necessary. Additionally with their panel, see above, to the front towards the user to be flush with the surfaces of the other cooking appliances, drawers, doors and the like of the kitchen furniture, which can improve the visual impression for the user.
  • these can also be combined vertically one above the other and/or horizontally next to each other with other built-in kitchen appliances such as warming drawers, vacuum mixing drawers and the like, which can also take on functions in the kitchen.
  • Warming drawers are used, for example, to keep the cooked food warm without further cooking and to preheat dishes.
  • vacuum mixing drawers food can be hermetically sealed in a vacuum in a package.
  • Such drawers as kitchen appliances are basically constructed in a similar way to the cooking appliances described above with a fixed cooking chamber, with drawers being designed to be significantly flatter, ie smaller in the vertical direction, and the user therefore has to be pulled out of the kitchen furniture towards the front to move in the vertical Direction from above to allow access to their interior.
  • the movable part of the drawer which can also be referred to as a pull-out, has a pull-out shelf, which serves to accommodate, for example, the cooking utensil in the vertical direction from above and can be moved in depth, for example, via rails arranged laterally in the transverse direction compared to the Inner housing of the drawer can be formed.
  • the pull-out shelf usually has a vertically aligned panel in the depth towards the front, which closes the interior of the drawer or its access opening when closed.
  • Such drawers also known as built-in drawers, usually have an overall height of about 14 cm in the vertical direction, at least in Germany.
  • Drawers are usually arranged in the vertical direction below a cooking appliance with a fixed cooking space, such as below an oven, below a steamer and the like, or in combination with another drawer in the vertical direction one above the other, but can also be installed individually and independently in kitchen furniture . Since the installation spaces for built-in kitchen appliances in kitchen furniture, which can also be referred to as niches, usually have a vertical height of approx. 60 cm, at least in Germany, a drawer with an overall height of approx. 15 cm and a cooking appliance with a fixed cooking chamber can have approx. 45 cm height can be combined with each other as built-in devices.
  • Such cooking devices such as ovens or steam cookers with oven function usually have a heating device which is arranged below the top of the inner housing in the interior and is aligned in the vertical direction downwards into the cooking chamber or toward the cooking chamber.
  • Such heating devices are therefore also referred to as top heat.
  • Such a top heat is usually realized, for example in an oven, by an uncovered heating coil mounted on the ceiling, which radiates intensively downwards and can thus achieve intensive browning of the food by means of thermal radiation.
  • a cooking appliance that can be used to identify a cooking utensil positioned in the cooking appliance is described in the publications DE 10 2017 121 401 A1 and DE 10 2008 031 378 A1 described.

  • a width grid of 18 inches, 24 inches or 36 inches is common for cabinets without built-in kitchen appliances.
  • the grid dimensions including studs of the surrounding kitchen furniture of 24 inches and 30 inches have prevailed, although 36-inch wide ovens are also known, which, however, are usually not designed as fitted kitchen appliances.
  • a better cooking result can be achieved with certain foods if the cooking process is completed as quickly as possible. It can therefore be advantageous for the cooking result in some cases to preheat a top heating element in a cooking appliance and to keep the energy transfer to the food as high as possible from the start of the cooking process. Preheating is also common in other cooking appliances such as ovens, pizza ovens and pans.
  • the top heating element of a cooking appliance according to the invention as a high-temperature drawer preferably has a radiant heating element with a heating strip.
  • this heating element can be covered with a glass ceramic.
  • the transmission of the glass ceramic for the radiated radiation can be limited. Losses can therefore occur when penetrating the glass ceramic.
  • the transmission can be about 50% with a glass ceramic that is approx. 4 mm thick.
  • the remaining 50% of the power can primarily heat the glass ceramic.
  • the glass ceramic can then also give off the heat mainly as radiation. This can cause a time delay in the radiation power on the food.
  • the radiant power increases only slowly and on the other hand, the radiator and the glass ceramic continue to radiate for significantly longer after they have been switched off.
  • the heating element system After switching on the top heating element, the heating element system, preferably consisting of heating element and glass ceramic, heats up with a certain time constant and radiates an ever higher temperature with stronger heating radiant power.
  • the glass ceramic can additionally reinforce this behavior. This delays the heating of the top heating element and thus also the cooking compartment and the food to be cooked.
  • this delay can be reduced by realizing automatic preheating in a cooking appliance according to the invention.
  • automatic preheating can take place when the cooking appliance is switched on.
  • the cooking appliance can carry out a heating impulse directly after switching on the appliance and heat the upper heating element, preferably and the glass ceramic, to a certain temperature.
  • This can have the advantage that the preheating time from the program selection to the insertion of the food can be shortened, since the cooking appliance is heated up before the program selection of the food to be cooked. If food is to be placed in the cold cooking compartment, the heating-up time from inserting the food to be cooked until the target temperature is reached can be shortened, since the cooking appliance is heated up before the food is put in.
  • automatic preheating can take place when the appliance door is opened.
  • the cooking appliance can carry out a heating impulse directly after opening the appliance door and heat the upper heating element, preferably and the glass ceramic, to a certain temperature. This can have the advantage that the preheating time from selecting the program to inserting the food can be reduced.
  • automatic preheating can take place when there is activity in front of the device.
  • the activity in front of the cooking appliance can be detected, for example, using a proximity sensor, camera or mobile phone data, etc.
  • a proximity sensor for example, a camera pointing into the cooking chamber or to the outside.
  • automatic preheating can take place from context-related information. If, for example, a guided recipe is used when preparing a dish, for example when cooking a recipe with the app of a mobile device, the information in the guided recipe can be used to predict when the cooking appliance has to be preheated and which parameters for the corresponding one cooking process are required.

  • Specifying a limit value for the operating time makes it possible to stop an unwanted preheating process in a timely manner.
  • the specified operating time is less than one minute, preferably in a range from 10 to 40 seconds.
  • the preheating is terminated, ie the first heating device and/or the second heating device is switched off.
  • One aspect of the method is that the first heating device is operated at high power when it is switched on. This enables rapid preheating of the interior.
  • a further aspect of the method is that the second heating device is operated at medium power or low power when it is switched on.
  • the second heating device is switched on at the same time as the first heating device. This ensures that when the cool cooking chamber is set up on the second separating element, the stresses in the separating element and/or in the cooking chamber do not become too great.
