Definitions

  • the present invention relates to a cooking device with means for pyrolytic self-cleaning, with a heated oven muffle, the free, front opening cross-section can be closed by an oven door.
  • Such a cooking device is known from US 3,710,776, the Oven door a front panel with a small see-through window and one attached to it has tub-like door floor. in the door floor is a window Front panel corresponding further viewing window arranged. Between the two a small shielding element is held for small viewing windows and other viewing windows, that corresponds to the size of the two see-through windows.
  • the shielding element between the two see-through windows to heat transfer from the oven muffle, which is clearly shown in pyrolysis mode, through the Reduce oven door to outside.
  • the shielding element can be used during normal cooking lowered in the oven door from the viewing window area become. This means that the operator can see into the oven muffle or Cooking space released.
  • a disadvantage of the prior art is the complex structure the oven door.
  • the object of the present invention is therefore a cooking appliance according to the preamble of claim 1 so that despite the simple structure of the oven door the front temperatures during pyrolysis operation are kept sufficiently low can.
  • a cooking appliance according to the preamble of the patent claim 1 achieved in that a flat shielding element is provided, the Easily removable for pyrolysis operation on the oven muffle or the oven door is attached and at least over substantially the free opening cross-section the oven muffle extends, thereby transporting heat out of the oven muffle to the oven door is reduced.
  • the cooking appliance can therefore be of a simple design Oven door must be equipped according to cooking devices without pyrolysis operation. It the use of the structurally complex and deep construction and thus is eliminated the usable cooking space volume reducing pyrolysis door.
  • the buyer attaches this shielding element himself for pyrolysis on the cooking appliance and takes it off again during normal operation of the cooking appliance.
  • the heat transfer out of the oven muffle through the oven door is in pyrolysis mode in particular reduced by the fact that the shielding element is essentially over extends the entire free opening cross-section of the oven muffle.
  • the arrangement is effective when the shielding element between the oven door and the oven muffle is arranged in the opening of the oven muffle and this closes.
  • the oven door advantageously has fastening elements on its inside to attach the shielding element. This is when the oven door is open simple assembly of the shielding element possible. Furthermore, if necessary Fastening elements that are particularly troublesome when cleaning the oven omitted on the oven muffle.
  • the oven muffle has muffle fastening elements for fastening the Shielding element. This is especially beneficial if one already exists existing mounting device for holding a food support on the inside the oven muffle is also used to attach the shielding element. It are therefore no additional annoying fasteners on the oven muffle to provide, but it can already be used otherwise for attachment of the shielding element are used.
  • the shielding element is an accessory of the cooking device, in particular for example a baking sheet or a drip pan. This is included with the cooking device anyway. It was also surprisingly found that just by attaching, for example, the baking sheet in the opening the oven muffle a significant and sufficient reduction in the front temperature the oven door is accessible.
  • the shielding element advantageously lies tightly on the circumference the inner wall of the oven muffle or the muffle flange and closes the Oven muffle on the front.
  • the shielding element can be provided with an additional one essentially on the circumference elastic sealing element.
  • the oven door has at least one area transparent front panel and a transparent door window panel arranged behind it on.
  • the free visible area in the cooking space is optimal if the transparent ones Areas of the front panel and the door window panel at least about the extend the free opening cross-section of the oven muffle.
  • This large clear view area is made possible according to the invention in that the flat shielding element essentially over the entire free opening cross-section of the oven muffle extends.
  • the circulating air fan advantageously remains in pyrolysis mode, at least at oven temperatures greater than about 150 ° C, in particular greater than about 300 ° C turned off. This prevents too much hot air from passing the shielding element is pushed to the oven door.
  • the cooking appliance has a security element that checks the presence of the shielding element and depends on it blocks or releases the pyrolysis operation. Because according to the invention a simple built-in oven door, which is actually unsuitable for pyrolysis operation it is particularly important that the pyrolysis operation only be started can, if the operator has mounted the shielding element appropriately.
  • an oven 1 has an oven muffle 3, which is open on the front. Muffle walls 5 limit the cooking space of the Oven 1, which is thermally insulated on the circumference in a manner known per se (not shown).
  • An oven door hinged to the oven 1 9 closes the oven muffle 3 or the cooking space on the front.
  • the oven door 9 has a trough-shaped door base 11 with a see-through opening.
  • the door base 11 is connected to a transparent front panel 13. In the inspection opening a transparent door window plate 15 is held on the door base 11. At the Door base 11 is attached to the muffle opening frame-like seal 17.
  • the structure of the oven door 9 is not suitable for the temperature of the Limit the front panel 13 to a permissible level in pyrolysis mode. Therefore a conventional drip pan 19 from above in each case closed at the bottom, vertically extending mounting grooves 21 of the door panel 11 pushed and thus securely attached. A bottom 23 of the trough-shaped drip pan 19 is immersed in the oven muffle 3 a. Only a small gap remains between the fat pan 19 and the inside of the muffle walls 5. At the same time is between the bottom of the fat pan 23 and the door window plate 15 a thermally insulating air chamber is formed.
  • An insulation plate 31 is made of, for example Glass fiber material attached to the inside of the front panel 13.
  • An operator initially has one equipped without an insulation plate 31 Removing the front plate (not shown) and a second with the insulation plate 33 provided front panel 13 to replace. It is advantageous if the Front panel 13 only via easily releasable snap-in connections to the door base 11 connected is.
  • the insulation plate extends to improve the thermal insulation 31 over essentially the entire area of the front panel 13. Alternatively it would also be possible to close the insulation plate 31 directly on the door window plate 15 keep.
  • a heat shield 41 has its inside Bottom area on both sides of the plug-in parts projecting essentially vertically 43 on. These are dimensioned such that they are formed on the muffle wall 5 horizontally running guide grooves can be inserted. These guide grooves (not otherwise) are used for inserting and holding food carriers, for example Baking trays.
  • the heat shield 41 is on its side facing the cooking space Mirrored side to reflect the heat radiation inwards. Farther it consists of poorly heat-conducting material to prevent the heat conduction To prevent the cooking chamber from the oven door 9.
  • the oven door 9 itself is a low-profile conventional door that can also be used in conventional stoves without the possibility of Pyrolysis operation can be used.
  • the heat shield 41 can be circumferentially with a Seal should be provided to prevent hot air from the oven muffle 3 is pressed.
  • the oven muffle 3 is so far open that the by an air blower (not shown) and the high pressure built up can be broken down.
  • a heat shield 51 is shown in FIG Oven muffle 3 immersed in the muffle flange 7.
  • the heat shield indicates this 51 in a laterally projecting edge 53 on a fastening hook 55.
  • the heat shield 51 For assembly the heat shield 51 with the fastening hook 55 in the front area of the Oven 1 arranged outlet openings 57 of the oven 1 hung. Doing so the presence of the fastening hook 55 of the heat shield 51 in the blow-out opening 57 detected by a detector 59.
  • the detector 59 reports this via a Signal line 61 to a safety circuit, not shown, of the oven 1.
  • a self-cleaning operating button is printed by an operator, the oven door 9 in itself locked in a known manner, and the pyrolysis operation starts.
