Definitions

  • the present invention relates to a cooking appliance with a Druckgarraum and a heater and a method for cooking in such a cooking appliance.
  • Such a cooking appliance in the form of a so-called combi steamer in which food to be cooked can be acted upon with hot air and / or steam, for example, from the DE 199 55 820 A1 known.
  • Another generic cooking appliance, namely in the form of a crucible, is from the EP 1 493 365 A1 known. Although these known cooking appliances have basically proven themselves, they are limited in their field of application. There is also a need to speed up the cooking process in such cooking appliances.
  • Object of the present invention is therefore to develop the generic cooking appliance such that the disadvantages of the prior art are overcome.
  • the heating device comprises at least one microwave source for emitting microwaves of wavelength ⁇ in the Druckgarraum.
  • a control or regulating device is in operative connection with the microwave source.
  • control or regulating device is in operative connection with a compressed air generating device and / or at least one sensor, in particular for detecting a pressure in the Druckgarraum and / or absorbed in Druckgarraum microwave energy.
  • the Druckgarraum in particular via at least one door or at least a lid, is pressure-tight closed, and / or the walls of Druckgarraums are formed of stainless steel.
  • Preferred cooking appliances are further characterized in that the dimensions of the Druckgarraums in all three spatial directions is not a multiple of ⁇ / 2.
  • Embodiments of the invention may be characterized in that a first microwave source is at least partially disposed in the lid or the door, and / or at least a first microwave conductor, in particular in the form of a coaxial conductor or waveguide, at least partially through the lid or door.
  • a second microwave source is arranged in a separate from Druckgarraum installation space, in particular electrical installation space.
  • a further embodiment is characterized in that a third microwave source is at least partially disposed in a side wall of Druckgarraums, and / or at least a third microwave conductor, in particular in the form of a coaxial conductor or waveguide, at least partially through the side wall.
  • a fourth microwave source is at least partially disposed in a bottom of Druckgarraums, and / or at least a fourth microwave conductor, in particular in the form of a coaxial conductor or waveguide, at least partially through the bottom.
  • the heating device comprises at least one electric heater, a heat conductor and / or a heat storage, preferably in each case in operative connection with the control or regulating device.
  • a steam generating device preferably in each case in operative connection with the control or regulating device.
  • Cooking devices of the invention may also be characterized by a display device and / or an operating device, in each case in operative connection with the control or regulating device.
  • the invention also provides a method for charging food in a cooking appliance according to the invention with pressure and microwaves, preferably with pressure and microwaves and contact heat and / or hot air and / or steam, during a cooking process, in particular cooking.
  • the invention is based on the surprising finding that cooking processes can be dramatically accelerated thereby, without sacrificing quality and without complicating an operator, by combining a pressure-gating function and a supply of microwave energy with one another in a cooking appliance.
  • energy supplied from the outside can be optimally transmitted via the pressure cooking, while additionally absorbing microwave energy.
  • This is particularly advantageous when cooking food with a high water content and / or in a liquid with a high water content, because on the one hand water when heating leads to build up a vapor pressure and on the other hand well absorbed microwaves.
  • the microwave application leads to an acceleration of the warming of the water or the liquid to a boiling temperature, which also builds up a certain vapor pressure faster.
  • the microwave power supplied to the food can also be regulated as a function of the amount of liquid and / or the amount of food that determine the absorption of microwave power.
  • a cooking appliance according to the invention comprises, for example, a crucible 2 with a lid 3 for limiting a Druckgarraums 4.
  • the crucible 2 via the cover 3 pressure-tight manner, so that a Druckgaren in the Druckgarraum 4 is possible.
  • a fluid can escape via a device outlet 5 with the interposition of a shut-off device in the form of a valve 6.
  • the crucible 2 can also over the lid 3 water from a water supply line 7 with the interposition of a further shut-off device in the form of a valve 8 are supplied via a nozzle 9, which allows cooking in a moist cooking atmosphere.
  • Microwaves of wavelength ⁇ can reach the pressure cooking chamber 4 via a magnetron 10 arranged in the lid 3 and a waveguide 11 in order to apply microwaves to the food which is not shown, without leaving the pressure cooking space 4. It is useful to form the crucible 2 completely made of stainless steel.
  • the crucible 2 and thus the Druckgarraum 4 is heated by a hot plate 12, which finally allows in particular a cooking by transfer of contact heat, hot air and / or in a not shown, heated water bath.
  • Both the valves 6, 8, the magnetron 11 and the heating plate 12 are controlled via a control device 13, which in turn is connected to a sensor 14 in Druckgarraum 4, so as to perform a targeted cooking taking advantage of all the Garterion described above which leads to optimum flexibility and considerable time advantage when preparing food.
  • the dimensions of the crucible 2 are further selected so that they do not coincide with a multiple of ⁇ / 2 in one of the three spatial directions, so that there is no standing wave in Druckgarraum 4 and thus can not build hot spots in the same.
