Definitions

  • the invention relates to a cooking device for a wok pan with a holder adapted to the shape of the wok pan and a heating device.
  • the wok pan as a traditional cooking vessel in Asian cuisine is also increasingly used in the western world. It consists of a hemispherical pot made of metal with a handle attached. In the countries of origin, heating is still carried out over an open fire. In modern kitchens, the only possible heat source is a gas hob to heat the wok pan from below with the gas flame. Suitable brackets have also been developed for this so that the wok pan can be safely placed over the gas flame.
  • the invention has for its object to provide a cooking device with which a wok pan can be heated by electrical energy in almost the same way as by a flame.
  • the holder for the wok pan consists of a cuvette in the form of an upwardly open spherical cap for receiving the wok pan, and the heating device is designed as an electrical induction heater.
  • the spherical cap-shaped cuvette is matched with its inner surface to the shape of the wok pan, which can thus be inserted into the cuvette so that on the one hand the induction heat is transferred to the wok pan without loss, and on the other hand the wok pan can still be moved.
  • the magnetic induction field heats the iron-containing material of the wok in the same way as a gas burner, so that there is no difference in the preparation of the dishes. Like a flame, the induction field can be switched off and the intensity can be regulated, so that there is no difference in this respect either.
  • the receiving cuvette is preferably made of ceramic or earthenware, which is well permeable to the magnetic induction field without being heated by it itself.
  • the glass ceramic material known for stovetops is also suitable for this purpose.
  • the cuvette can be installed in a table or single device, the housing of which accommodates the electrical generator for the induction coil or the induction coils.
  • Several cuvettes can also be arranged on the top of the housing in order to be able to cook in two or more wok pans at the same time and / or to work with wok pans of different shape and size.
  • Another possibility is to integrate the cooking appliance into the hob of an electric cooker.
  • the surface of the cooker is given a circular cutout in which the receiving cuvette for the wok pan is inserted in a sealed manner.
  • the wok pan can then be used on the stove like other cooking vessels.
  • Induction-heated cookers which have the same control technology as the cooking device according to the invention are particularly suitable.
  • the drawing shows an example of a cooking device according to the invention in section.
  • the wok pan 1 forms a hemispherical vessel with a handle-like handle.
  • the vessel wall consists of iron or an iron-containing material.
  • a cuvette 2 made of ceramic material in the form of a spherical cap serves to hold the vessel, the lower part of which holds the wok.
  • the cuvette 2 is fitted into the surface of a hob or a table device in the manner shown.
  • the outer surface of the wok pan 1 and the inner surface of the cuvette 3 do not have the same radius of curvature, but the cuvette is curved with a larger radius than the cuvette.
  • the wok pan can be rotated and swiveled in the cuvette in order to move and mix the items to be cooked therein. Since the energy transfer takes place inductively, a complete flat system is not necessary.
  • the ratio of the radii of curvature must be selected so that the wok pan 1 is sufficiently mobile on the one hand, and on the other hand is still securely held in the cuvette 3. This requirement is met in that the radius of the cuvette is 3 to 5% larger than that of the wok pan, ie the radii are calculated using the following equation: where R denotes the radius of the cuvette spherical cap and r the radius of the wok pan spherical cap.
  • induction coils 4 On the underside of the cuvette 2 there are induction coils 4, which are supplied with energy by an electric generator 6.
  • induction coils 4 two layers of induction coils 4 are provided, of which the lower layer supplies thermal energy only to the middle or lower region of the wok pan, in which most of the cooking material is located.
  • the induction coil lying directly on the underside of the cuvette runs in a spiral shape in such a way that the turns are closer to one another in the middle than in the outer areas.
  • the induction coil or induction coils are attached to the underside of the cuvette using a hardenable, temperature-resistant two-component adhesive.
  • the items to be cooked are also heated locally in the wok pan in the same way as over a gas flame.
  • the induction heating can be controlled without inertia, and the ceramic cell is not heated by the induction field, so that the energy losses are very low.
  • a cuvette made of ceramic material can be produced in such a way that a lithium-aluminum-silicate mixture is shaped into a cuvette of suitable shape and size in a pottery process and this burns after drying at 1150 ° C. Then a glaze made of aluminum silicate is applied with a small amount of lead and fired at 1000 ° C.
  • a particularly suitable base material consists of the base materials clay and lithium silicate which are mixed in such a ratio that the coefficient of thermal expansion of the finished cuvette at 800 ° C has a value of ⁇ 2 ⁇ 10 ⁇ 6 / ° C.
  • a wall thickness of the cuvette is important factor. For reasons of strength, the wall must not be too thin. On the other hand, the effectiveness of the induction heating decreases with increasing wall thickness, and the thermal stresses in the wall material also increase. A wall thickness of 5 to 7 mm best meets the requirements.
  • the cuvette 3 is inserted in the manner shown in the plate 2 of a tabletop or a cooker, so that it is flush with the surface.
  • the cuvette must be elastically embedded in the cover plate 2 so that movements, shocks, thermal expansion and. Like. Can not have a harmful effect.
  • the cuvette must be tightly and seamlessly enclosed.
  • the attachment and sealing is carried out according to the invention by an intermediate layer 5 made of temperature-resistant silicone plastic.
