Definitions

  • the invention relates to a cooking appliance according to the preamble of Claim 1 and a cooking space divider according to claim 13.
  • the cooking space of the oven mentioned above is thus through the radiation-permeable Radiation window heated due to the heat radiation from the radiant heater, so that, for example, the desired working temperature is extremely cold can be reached quickly.
  • the radiation windows are translucent or transparent and allow that without a separate, within the Oven muffle grill radiators to be arranged - so with the same Radiant heaters, which are also provided for normal heating of the oven are - can be grilled.
  • the radiation windows are through a plate made of glass ceramic or the like and preferably formed on flange profiles of the surrounding Wall parts of the associated muffle wall attached.
  • the object of the invention is achieved by a cooking appliance according to the Claim 1 and solved by a cavity divider according to claim 13.
  • a lower radiation window in combination arranged for example from glass ceramic and an upper radiation window.
  • the top Radiation window has a transmittance, the value of which is at least in one the wavelength range of heat radiation relevant for cooking from about 0 to 10 ⁇ m, in particular in a wavelength range from 0.5 to 5 ⁇ m, essentially is constant. This ensures that a constant, sufficiently large proportion the heat rays whose wavelengths are in the relevant wavelength range, is let through by the upper radiation window.
  • the constant value of the transmittance of the upper radiation window becomes achieved, for example, by a lattice structure.
  • the size of the Transmittance especially from the average mesh size of the Lattice structure, i.e. with a larger mesh size, the value of the Transmittance of the lattice structure.
  • the lattice structure is preferably a woven fabric made of ceramic fibers, strong in cooking from the top heat radiator is heated. Due to the strong heating fat splashes or the like on the Burnt tissue, which creates a certain self-cleaning effect on the tissue becomes.
  • the mesh size of the fabric is chosen such that there is a desired Value of the transmittance of the upper radiation window. As an additional Protective measure for a user can use the ceramic fiber fabric with a grounded metal grille.
  • the radiant heaters can be formed by quartz radiant heaters his. Quartz radiant heaters can be provided with a shield with which the heat radiation is reflected away from the shield. This is particularly from This is an advantage if directional heat radiation is to be avoided. There thus an efficient use of limited cooking space is possible Quartz radiant heater used in particular in more compact cooking appliances, whose cooking space is small.
  • the upper and / or lower heat radiator arrangement are at least largely identical in construction.
  • the upper heat radiation heater inside the muffle is advantageous arranged. On the one hand, this causes insulation problems in the area of the top wall of the Cooking appliance muffle minimized. On the other hand, there is no need for installation openings for inserting the radiator assembly of the top heat radiator in one Muffle wall of the cooking device muffle to be provided.
  • the glass or glass ceramic cover plate of the cooking space divider according to the invention is exposed to much lower loads than, for example, a glass or Glass ceramic cover plate for a hob. Therefore, the cover plate of the Cooking space divider are formed with a comparatively low material thickness.
  • the total weight of the cooking space divider is due to the lower material thickness reduced while at the same time increasing the radiation permeability of the cover plate.
  • a material thickness of 3 mm is sufficient, whereas the material thickness a glass ceramic cover plate for a hob is about 4 mm.
  • a cooking device of the first exemplary embodiment has a cooking device muffle 1 with a cooking space 3, which is closed with a double full glass door 5 on the front.
  • the upper Radiator arrangement 7 has a tub-like radiator housing 9, in which a Insulating body 11 is added.
  • a band heating conductor 8 is embedded on the insulating body 11 .
  • the band heating conductor 8 runs not only in the form of a ring in the peripheral region of the upper radiator arrangement 7, but also as Panel radiators over the entire surface of the upper radiator assembly 7.
  • the peripheral edge of the tub-like radiator housing 9 frames an upper one Radiation window 13 of the upper radiator arrangement 7 through which the band heating conductor 8 Radiates heat radiation in the cooking space 3.
  • the upper radiation window 13 is through a fabric 15 made of ceramic fibers.
  • the fabric 15 covered by a coarse-meshed grounded metal grid 17.
  • both the top heat and Lower heat radiators 8 and 21 heat radiation through the upper and lower Radiation windows 13 and 28 into the cooking space 3.
  • the degree of transmission determines of the upper and lower radiation windows 13 and 28, which parts of the Heat radiation from the upper and lower radiation windows 13 and 28 be allowed through.
  • a transmittance of the upper radiation window 13 with a constant value ⁇ 1 of, for example, 0.8 has been selected in the wavelength range.
  • this value of the transmittance is essentially constant at least in a wavelength range from 0 to 10 ⁇ m. This ensures that a constant portion of the heat rays, the wavelengths of which are between approximately 0 and 10 ⁇ m, is let through by the upper radiation window 13, at least to a portion of 80%.
  • the heat rays with a wavelength of 2.9 ⁇ m are very high-energy and therefore important heat rays for effective cooking, as shown in the diagram 4 is illustrated.
  • those of the strip heating conductors are located 8 and 21 at a temperature of 1100K emitted heat rays of a wavelength ⁇ of 2.9 ⁇ m near a maximum of the energy distribution curve.
  • the spectral energy distribution ⁇ P / ⁇ shown in FIG a black body that approximates the heating cable conductors 8, 21 is equal.
  • FIG. 2 shows a second exemplary embodiment of the cooking device according to the invention shown.
  • the back of the cooking appliance is in the manner of a wall cabinet on one vertical kitchen wall 39 mounted.
  • the cooking space 3 inside the cooking device muffle 1 can can be checked via a viewing window 41 arranged in the front of the cooking appliance.
  • the Cooking device muffle 1 has a muffle opening 33 on the bottom, which merges with the bottom side Door 5 is lockable.
  • the bottom door 2 is shown lowered, wherein it is in contact with a worktop 37 of a kitchen device with its underside.
  • the bottom door 5 is connected to lifting elements 35 of the cooking device.
  • the Lifting elements 35 can be indicated by a dashed line in FIG Drive device 43 of the cooking device can be adjusted.
  • the bottom door 5 is in contact with a by means of the lifting elements 35 the muffle frame 45 surrounding the cooking space opening 33.
  • the bottom-side door 5 has a door frame 47 which on its cooking chamber 3 facing side is open. This open side is through a glass ceramic plate 28 covered.
  • the lower radiator arrangement 19 is below the glass ceramic plate 28 arranged.
  • the peripheral edge of the trough-shaped radiator housing 23 is the lower radiator assembly 19 connected to an underside of the glass ceramic plate 28.
  • the cooking chamber 3 is Cooking appliance muffle 1 divided by a plate-like cooking space divider 30, which is not guides shown on the side walls of the cooking device muffle 1.
  • the Cooking compartment divider 30 has, according to FIG. 5, a trough-like housing 38.
  • Housing 38 contains an insulating body 36 on which a strip heating conductor 34 is embedded is.
  • the band heating conductor 34 does not only run in a ring shape in the peripheral region of the Cooking space divider 30, but extends as a panel radiator over the entire Area of the cooking space divider 30.
  • the bottom one is in operation of the cooking device with the cooking space divider 30 inserted therein Radiator arrangement 19 by a control device, not shown, of the cooking appliance disabled. Instead, the cooking space divider 30 is used with electrical current supplied so that the cooking space area between the Top heat radiation heater assembly 7 and the cooking space divider 30 is heated.
  • the value of the transmittance of the upper radiation window 13 determines and the glass ceramic cover plate 32 of the cooking space divider 30, which parts of the Heat radiation from the upper radiation window 13 or the glass ceramic cover plate 32 of the cooking space divider 28 are allowed to pass.
