Definitions

  • the invention relates to a cooking appliance with a housing and a cooking chamber arranged in the housing, the cooking chamber being delimited by the cooking chamber walls, a camera for observing the cooking chamber being arranged in the housing outside the cooking chamber, with a first viewing window in a first region of the cooking chamber walls is let in between the camera and the cooking chamber, and wherein the first viewing window has cooling on a side facing away from the cooking chamber.
  • the cooking appliance is designed as a baking oven with a pyrolysis function.
  • Cooking devices such as ovens, in which viewing windows are embedded in the cooking chamber walls, are already known.
  • viewing windows are provided in a mostly vertical front, in particular in a cooking chamber door, through which a person using the cooking appliance can look, for example to observe or check the cooking process of an item to be cooked.
  • viewing windows are arranged in the cooking chamber walls between the cooking chamber and a camera, for example in a horizontal cooking chamber ceiling delimiting the cooking chamber at the top.
  • a camera is used, for example, as a sensor for controlling the cooking appliance, such as automatic shutdown depending on the degree of cooking detected by the camera or automatic browning of the food and/or allows a person using the cooking chamber from a distance via a terminal to observe.
  • the cooling in the area of the camera ensures that temperatures are lower than those in the cooking chamber to prevent damage to the camera.
  • the cooling also results in a reduced temperature on the side of the first viewing window facing the cooking chamber compared to the rest of the cooking chamber, which disadvantageously does not reach a sufficient decomposition temperature for organic impurities in certain operating states of the cooking appliance and causes these impurities to polymerize on the first viewing window, so that a contamination that can only be removed with great effort comes from the first viewing window.
  • contamination occurs during pyrolytic cleaning of the cooking appliance with very high temperatures of over 400° C. in the cooking chamber, during which sufficient decomposition temperatures for the organic contaminants are not reached at the first viewing window due to the reduced temperatures.
  • the soiling then impedes the free view of the camera through the first viewing window, so that controlling the cooking appliance using the camera and/or observing the food to be cooked on a terminal is disrupted.
  • such contamination can cause distortions in a color spectrum coming through the first viewing window, which impedes control of the cooking appliance by the camera.
  • a baking oven in which a coating with hydrophilic and/or lipophilic properties is applied to the walls of the cooking space in order to collect impurities in the area of these coatings and to reduce them in other areas of the baking oven. The cleaning of the oven can then be reduced to the areas of the coatings.
  • the coating is combined with a catalytic coating and a heating layer to remove accumulated contaminants.
  • the object is therefore achieved by a cooking appliance as described above, in which the first viewing window is formed by a transparent substrate and a catalytic layer applied to the substrate on the cooking chamber side for decomposing organic impurities, the catalytic layer being formed with a transparent layer thickness.
  • first component for example "first component”, “second component” and “third component”
  • this numbering is intended purely for differentiation in the designation and does not represent any interdependence of the elements from one another or a mandatory order of the elements
  • a device does not have to have a “first component” in order to be able to have a “second component”.
  • the device can also include a “first component” and a “third component”, but without necessarily having a “second component”.
  • Several units of an element of a single numbering can also be provided, ie for example several "first components”.
  • a cooking appliance is designed in particular as an oven in which, for example, temperatures of approximately 100-250° C. are provided in the cooking chamber for the preparation of food.
  • the cooking appliance also preferably has a pyrolysis function, in which the temperature in the cooking chamber is increased to up to 500° C., so that organic impurities present on the cooking chamber walls are decomposed and detached from the cooking chamber walls. Organic contamination occurs when cooking food, in particular from fats and oils that are released from the food and settle on the walls of the cooking space.
  • the cooking appliance can also be designed as an oven with an integrated microwave.
  • the cooking chamber of the cooking appliance is preferably designed as a cavity in the housing that is insulated against an outer wall of the cooking appliance by means of thermal insulation.
  • the cooking space can preferably be filled with food to be cooked via an opening or such food to be cooked can be removed from the cooking space via the opening.
  • Means for heating the air in the cooking chamber and means for circulating the air in the cooking chamber are preferably provided in or on the cooking chamber.
  • air ducts and/or air baffles are also provided in the cooking chamber or in the walls of the cooking chamber, the geometry of which influences the air flow in the oven.
  • the term air is also used here in the sense of vapors located in the cooking chamber, for example when food to be cooked is located in the cooking chamber and corresponding substances and steam are emitted into the air.
  • means for radiating heat can be provided in the cooking chamber.
  • the first viewing window is sealed in particular with respect to the wall of the cooking space in which it is embedded, so that no air from the cooking space can get past the first viewing window into the area of the camera.
  • the camera is preferably located above the food to be cooked, ie above an upper cooking space wall extending in a horizontal plane, and is directed downwards at the food to be cooked. Such a positioning allows a particularly good view of the food to be cooked. Insofar as the first viewing window has cooling, this can only be cooling for the first viewing window or cooling that also cools other areas or components around the camera and/or the camera itself.
  • the cooling is designed as air cooling, with cooled air circulating around the camera in an air volume adjacent to the first viewing window, so that the cooled air flows along the side of the first viewing window facing away from the cooking chamber.
  • the cooling can also be liquid cooling.
  • the first viewing window can also be designed as a part of a multiple pane on the cooking chamber side, with a coolant flowing along in the spaces between the panes.
  • the first viewing window has a catalytic layer.
  • a catalytic layer By means of such a catalytic layer, it is possible to reduce the decomposition temperature of organic impurities located on the first viewing window.
  • the organic contaminants at the first viewing window are decomposed more easily, in particular even at temperatures at which the contaminants would polymerize without a catalytic layer.
  • the first viewing window is therefore only soiled to a reduced extent, so that an improved view for the camera can be achieved, in particular even after a large number of use and/or cleaning cycles.
  • the catalytic layer is formed in a transparent layer thickness and therefore particularly advantageously has no relevant influence on the view through the first viewing window.
  • a transparent layer thickness can be selected depending on the material or materials used for the catalytic layer.
  • a layer thickness in which the catalytic layer produces a sufficient catalytic effect while remaining transparent can be achieved with materials that have a sufficient Have temperature resistance, in particular for the temperatures prevailing in the cooking chamber during a pyrolysis cleaning.
  • the cooking appliance has an opening for filling the cooking chamber and at least one cooking chamber door for closing the opening, the cooking chamber door forming a cooking chamber wall, a second viewing window being embedded in the cooking chamber door, and the second viewing window being covered by a transparent substrate and a catalytic layer applied to the substrate on the cooking chamber side for decomposing organic impurities is formed, the catalytic layer being formed in a transparent layer thickness.
  • the catalytic layer on the second viewing window can be formed in the same manner and from the same material or materials as the catalytic layer on the first viewing window. Contamination by organic impurities also occurs on the surface of the second viewing window on the cooking chamber side.
  • contamination can also occur on the second viewing window in a manner similar to that on the first viewing window as a result of polymerization of organic contaminants, since the second viewing window is in contact with an environment of the cooking appliance on a side facing away from the cooking chamber and, depending on the air temperature in this environment, on the Cooking chamber side of the second viewing window can be present in relation to the rest of the cooking chamber reduced temperature.
  • the catalytic layer on the second viewing window achieves the same advantages as the catalytic layer on the first viewing window, so that dirt on the second viewing window is reduced or avoided and the view through the second viewing window, for example for a person standing in front of the garrum door is improved.
  • the second viewing window has cooling on a side facing away from the cooking chamber.
  • the temperatures on the cooking chamber side of the second viewing window are particularly reduced compared to the rest of the cooking chamber, so that the problem of the polymerization of organic impurities is particularly high consists.
  • the catalytic layer therefore achieves particularly great advantages in that contamination is avoided.
  • the cooling of the second viewing window can, for example, be in the form of air or liquid cooling.
  • the second viewing window is designed as a part of a multiple pane on the cooking chamber side, with a coolant flowing along in the spaces between the panes.
  • the catalytic layer of the first viewing window and/or the second viewing window has at least one platinum metal, in particular platinum, palladium, iridium and/or ruthenium.
  • platinum metals have a particularly high thermal stability, so that there is no risk of damage to the catalytic layer even when carrying out pyrolysis cleaning at temperatures between 400° C. and 500° C.
  • the catalytic layer of the first viewing window and/or the second viewing window preferably has at least one metal oxide, in particular copper oxide, magnesium oxide and/or manganese oxide.
  • a very good catalytic effect is also achieved with such metal oxides even with thin layer thicknesses, so that the catalytic layer can be applied to the substrate sufficiently thinly to be transparent.
  • metal oxides have a particularly high thermal stability, so that there is no risk of damage to the catalytic layer even when pyrolysis cleaning is carried out at temperatures between 400° C. and 500° C.
  • the catalytic layer preferably has a plurality of substances, in particular at least one platinum metal and at least one metal oxide, in order to set particularly favorable catalytic properties for a specific temperature range.
  • the layer thickness of the catalytic layer of the first viewing window and/or the second viewing window is between 80 nanometers and 1500 nanometers, preferably between 130 nanometers and 1300 nanometers, in particular greater than 16 nanometers and/or less than 1100 nanometers.
  • a sufficient catalytic effect to avoid contamination can be achieved, with the catalytic layer being transparent.
  • the layer thickness is preferably chosen to be as thick as possible with existing transparency in order to make the catalytic layer as durable as possible.
  • the catalytic layer of the first viewing window and/or the second viewing window is applied by a spraying method, an immersion method, an ALD method, a PVD method, a CVD method and/or a sputtering method.
  • a catalytic layer can be formed in each case with a transparent layer thickness and sufficiently adhering to the substrate.
  • ALD stands for "atomic layer deposition” and describes a process for the deposition of extremely thin layers, up to atomic monolayers, on a starting material.
  • PVD stands for "physical vapor deposition” and describes a vacuum-based process in which the material for the catalytic layer is converted into the gas phase and condenses on the substrate to form the catalytic layer.
  • CVD stands for "chemical vapor deposition” and describes a process in which the catalytic layer is deposited on a heated surface of the substrate as a result of a chemical reaction from the gas phase.
  • atoms are released from a solid body by bombardment with high-energy ions and go into the gas phase.
  • the sputtering process can be used in particular in connection with the PVD process for converting the material for the catalytic layer into the gas phase.
  • At least one of the first viewing window and the second viewing window between the substrate and the catalytic layer on a support layer is particularly preferably designed as a porous layer or a frit for receiving the catalytic layer and can serve, for example, to increase the binding force between the catalytic layer and the substrate.
  • the support layer can also serve to provide a framework for the catalytic layer such that the surface area of the catalytic layer is increased for improved mass transfer.
  • the catalytic layer even if it is applied to the carrier layer, is understood to be applied to the substrate.
  • the carrier layer particularly preferably has at least one silicon oxide, such as a silicon dioxide.
  • the carrier layer can optionally be applied to the substrate in a coating process that precedes the coating with the catalytic layer, or the carrier layer and the catalytic layer are applied to the substrate simultaneously in a common coating process.
  • the carrier layer in which it is applied to the substrate before the catalytic layer is applied, the carrier layer is particularly preferably burned in before the catalytic layer is applied to the substrate.
  • a particularly good bond between the carrier layer and the substrate is achieved by baking.
  • the support layer and the catalytic layer are applied together, they can also form a combined layer that performs the function of a support layer and the function of the catalytic layer.
  • a combined layer is understood on the one hand as a catalytic layer applied to the substrate and on the other hand as a carrier layer arranged between the catalytic layer and the substrate.
  • the substrate of the first viewing window and/or the second viewing window is made of glass.
  • glass offers the particular advantages that it is transparent, has good thermal stability and is chemically inert to the catalytic layer and/or the carrier layer.
  • the solution described above includes the teaching that the ceramic layer has a lipophobic property.
  • the ceramic layer thus forms a large contact angle with oils and/or fats, so that such substances cannot be deposited on the first viewing window. This advantageously ensures that no organic impurities are deposited on the viewing window, which would impair the view through the viewing window.
  • the first viewing window thus remains free of dirt and condensation, so that overall a significantly improved view through the viewing window is made possible.
  • a lipophobic property of the ceramic layer can be achieved, for example, by combining different ceramics in the ceramic layer and thus forming a combined layer. Ceramic particles can also be embedded in another material or other materials, for example in a matrix of another material or other materials, with a combined layer also being formed. Furthermore, a lipophobic property can also be achieved, for example, by additional structuring or chemical treatment of the surfaces of the ceramic layer.
  • the cooking appliance has an opening for filling the cooking chamber and at least one cooking chamber door for closing the opening, the cooking chamber door forming a cooking chamber wall and the first viewing window being embedded in the cooking chamber door.

  • the hydrophilic ceramic oxide coating described above also achieves the advantage that no drops form on the first viewing window that run down the first viewing window and meet a seal at a lower end. Instead, a layer of water forms on the first viewing window, which has a more favorable surface-to-volume ratio compared to the droplets and thus promotes rapid mass transport of the liquid back into the vapor phase. In this respect, there is no need for a liquid-tight seal with respect to the environment in the lower area of the first viewing window in order to prevent liquid from escaping from the cooking appliance. It is therefore possible to use seals that are suitable for higher temperatures but are only vapor-tight.
  • a cooking appliance with a housing and a cooking chamber arranged in the housing, the cooking chamber being delimited by the walls of the cooking chamber, a camera for monitoring the cooking chamber being arranged in the housing outside the cooking chamber, with the Cooking chamber walls a first viewing window is let in between the camera and the cooking chamber, the first viewing window being formed by a transparent substrate and a hydrophilic ceramic layer applied to the substrate on the cooking chamber side, and the ceramic layer being formed in a transparent layer thickness.
  • the cooking device for a camera located inside the housing has the advantage that water deposited on the first viewing window forms a small contact angle and thus a thin layer of water is created, which produces less refraction than water droplets that would otherwise form.
  • the water thus forms no fogging on the first viewing window, as already described above with regard to the first solution, and the view through the first viewing window is not fogged up or prevented by such a fogging.
  • the camera is preferably arranged above the cooking chamber, with the first viewing window being embedded in a cooking chamber wall delimiting the cooking chamber at the top and extending in a horizontal plane.
  • the ceramic layer of the first viewing window also has a previously described lipophobic property, so that no dirt can accumulate on the first viewing window.

  • the cooking appliance has a door seal for sealing the opening closed by the cooking chamber door from the surroundings of the cooking appliance, the door seal being made in particular of glass silk.
  • a seal prevents steam and/or liquid from escaping from the cooking chamber into the vicinity of the cooking appliance at the door.
