Definitions

  • the invention relates to a microwave domestic appliance, in particular for uniform cooking, the microwave energy used for the cooking process being generated by a magnetron and conducted directly or by means of a waveguide, preferably a rectangular conductor, to at least one feed opening of a cooking space and coupled into it.
  • the object of the invention is therefore to develop an arrangement with the aid of which the cooking, regardless of the food to be cooked and its volume, is realized without adverse effects
  • the arrangement according to the invention for solving this problem is characterized in that means for combined steam-microwave cooking are arranged in the cooking chamber, which have a water film insulated from the food to be cooked, the water film primarily protecting the food against direct microwave radiation directed to the microwave feed opening is.
  • a further advantageous arrangement according to the invention is characterized in that a control connected to the magnetron reduces the ventilation of the cooking space during the cooking process and that the control selectable microwave cooking power to the cooking space in which a food item housed in a steam cooker is located, as impulse power with a Feeds adjusted cycle ratio feeds.
  • the arrangement according to the invention combines the advantages of microwave cooking and steam cooking. There is no overheating as a result of non-uniform microwave energy density distribution, an expensive steam supply or such generation is not necessary, the nutrient-preserving cooking guaranteed by the arrangement according to the invention being particularly advantageous.
  • the constructive design of the steam cooker allows the use of the lower part as serving and cooking dishes.
  • the microwave domestic appliance 1 is a microwave domestic appliance 1 with a control panel 2, not shown, a cooking space 3, a controller 4 for a magnetron 5, the microwave energy generated by means of a waveguide 6 via a feed opening 7 to a steam cooker 8 located in the cooking space 3, the contains a food 9, recognizable.
  • the feed opening 7 acts according to FIG. 1 from the view of the cooking space 3 as an upper feed opening 7.
  • the steam cooker 8 is designed accordingly.
  • the steam cooker 8 is varied accordingly with regard to its internal structure.
  • the microwave energy can also be fed in via the feed opening 7 by means of a rotating antenna or field stirrer, which can be located in the cooking space or waveguide.
  • the steam cooker 8 consists of microwave-permeable materials, such as glass, ceramic, plastic. It allows combined steam and microwave cooking via differently designed steam pressure compensation surfaces. This is due to the thickness of the water films introduced, both the Vapor pressure is limited and the microwave energy supply, which can act directly on the food 9, is metered.
  • the maximum steam pressure occurring in the steam cooker 8 is limited by the weight of a steam cooker lid 11, the water films being selected so that this maximum steam pressure remains unmatched. Since part of the water vapor spreading around the food 9 condenses, the water film jacket thus created acts as a protection against peripheral overcookings and burns
  • a steam cooker 8 is shown, the overall structure of which requires a microwave coupling into the cooking space 3 from above. This is illustrated in FIG. 2a by a symbolically indicated rotary antenna 10.
  • the steam cooker 8 consists of a steam cooker lid 11, an insert 12 and a steam cooker lower part 13. On the bottom of the steam cooker lower part 13, which can be grooved, a food 9, for example undivided cauliflower, is introduced. Water is placed in the insert 12 so that a water film a few millimeters thick is formed.
  • the cooker software or automatic program supplies the microwave energy required for the cauliflower case by the controller 4.
  • the insert 12 of the steam cooker 8 covers approximately 80% of the microwave inlet area of the steam cooker 8 and only around 10% each of an edge surface 14, less than 20% of the microwave energy generated by the steam cooker 8 reaches the food directly.
  • the water film With increasing microwave energy supply, the water film finally evaporates, the water vapor passes through the edge surfaces 14 and surrounds the food.
  • the water vapor which initially condenses on all sides, also protects larger volumes of food to be cooked, here, for example, cauliflower, also against peripheral burns which can be caused by reflected microwave energy.
  • the food to be cooked is subjected to a combined microwave and steam cooking, since after the water film has evaporated, the microwave energy can act more directly on the food 9 both from the insert 12 and from the rest of the vessel rim shown, the overall structure of which requires a microwave coupling from below into the cooking space 3.
  • this is indicated by a symbolic Rotating antenna 10 * clarified.
  • the food 9 is placed in an insert 12 * here.
  • the water film is generated so that the food 9 is again protected from direct microwave energy radiation until the combined steam-microwave cooking takes place, as already described.
  • An improved supply of steam to the food to be cooked 9 can be ensured in that not only the edge surfaces 14 but also a perforated pattern in the bottom of the insert 12 * allow steam to enter.
