Definitions

  • the invention relates to a door sealing strip of a cooking device according to the preamble of claim 1 and a cooking device according to the preamble of claim 8.
  • a cooking device can be, for example, an oven, a stove, a grill or a microwave device, in particular such a cooking device with a pyrolytic self-cleaning function.
  • a sealing strip in the manner of the preamble of claim 1 is known from DE-G 91 06 860.6, which shows a sealing jacket made of glass silk with a wire core running axially inside the sealing jacket.
  • the oven flange can be thermally decoupled from the oven by means of slots or other means. So that these slots are not visible to the customer on the one hand and sealed against the oven, on the other hand, they lie behind the oven seal, in special versions basically a circumferential groove of the oven flange in which the oven seal is arranged. Due to the thermal decoupling, a strong temperature jump now occurs at the decoupling point. On the oven side of the slots, the temperatures are very high, especially in pyrolysis operation, e.g. B. greater than 350 ° C.
  • the object of the invention is to provide a cooking device door seal which is suitable both for high temperatures, such as occur, for example, in a pyrolysis operation, and also has a permanently good sealing effect.
  • the invention is characterized according to claim 1 by a core strand made of a highly heat-resistant fiber material as a sealing element and by a jacket made of a likewise, but less heat-resistant plastic as a sealing element, which partially surrounds the core strand with the exception of a gap exposing the core strand, in which the core strand a hotter cooking device area can be sealingly applied than the jacket, which can be sealingly applied to a less hot cooking device area.
  • the advantages of the invention lie in particular in the easier cleanability (smooth surface), the better visual impression (fiber material, in particular glass silk quickly becomes stained) and in the better technical function (better sealing effect, in particular since the seal is not so saturated with grease and hardens).
  • the core strand can be formed by any suitable fiber material which is temperature-resistant in accordance with the requirements.
  • the core strand can, for example be formed by a glass fiber seal.
  • the core strand can be replaced by a
  • Glass fiber seal or a glass braid hose can be formed.
  • Glass is highly heat-resistant and an inexpensive material.
  • the jacket is preferably made of silicone.
  • Silicone is a well-known heat-resistant sealing material with very good sealing properties.
  • the jacket can also be formed from any other plastics which are sufficiently heat-resistant in accordance with the requirements.
  • the core strand is preferably coated with the material of the jacket, for example by spraying, dipping or other known coating techniques.
  • a coating is resource-saving and inexpensive, since only small amounts of the jacket material are necessary to partially surround the core strand with the jacket. Furthermore, a coating adheres non-slip to the fiber material and closes fiber gaps.
  • the jacket preferably surrounds the core strand over a wrap angle of more than 180 °. This largely avoids contamination of the fiber material, for example with grease, a very good sealing effect is achieved, and the fiber material is largely invisible. The visual impression is determined by the plastic.
  • the at least one door seal strand is designed according to at least one of claims 1 to 7, that the core strand is arranged in the jacket gap contacting a high-temperature cooking device area and that the jacket is arranged contacting a cooking device area which is lower in temperature relative thereto.
  • the core strand of fiber material comes into contact with the high temperatures of the cooking chamber.
  • the coat e.g. B. made of silicone, only comes into contact with sealing points that have a temperature below 300 ° C, for which silicone is just still suitable.
  • a single closed door seal strand can be provided, which surrounds the cooking space opening in a ring shape.
  • two or more door seal strands can be provided which partially surround the cooking chamber opening.
  • a door seal strand which can be the only door seal strand or one of the two or more door seal strands.
  • the cooking space flange is provided with at least one heat decoupling slot, that the core strand is arranged in contact with the hot side of the cooking space flange in the jacket gap, but the jacket is spaced from this hot side.
  • Heat decoupling slot against the cooking space Furthermore, lowering the temperature in an outer region on a side of the door sealing strip facing away from the cooking space and thereby also reducing the temperature of the jacket on the cooking space door.
  • the jacket can also be arranged in contact with a cold side of the cooking space flange which is thermally decoupled from the hot side by the at least one heat decoupling slot.
  • the jacket can be arranged in contact with the oven door.
  • Advantage More beautiful appearance and better sealing effect of the door sealing strip, since the jacket against the door achieves a better sealing effect than fiber material.
  • the door sealing strand can be fastened to the cooking space flange, the cooking space door sealingly abutting the jacket of the door sealing strand in the closed state and being spaced apart from the door sealing strand in the open state.
  • the inside of the door opposite the cooking space, which in its open position is particularly exposed to more dirt than the vertically extending cooking space flange, can be designed as a smooth surface that is easier to clean than with door seal string attached to it.
  • the silicone coating can, for example, extend over a wrap angle of approximately 200 °. However, it is also conceivable to pull the silicone coating into the heat decoupling slot (wrap angle, for example, approximately 270 °).
  • FIG. 1 shows a partial cross-sectional view of a cooking appliance according to the invention along the plane I-1 of FIG. 3;
  • FIG. 2 shows a partial cross-sectional view of a further embodiment of a cooking appliance according to the invention along the plane I-1 of FIG. 3;
  • FIG. 3 shows a front view of the cooking device with the cooking chamber door opened downward; 4 shows a cross section through an embodiment of a door sealing strip according to the invention;
  • Fig. 5 shows a cross section through a further embodiment of a door seal strand according to the invention.
  • a cooking appliance 2 has a cooking space flange 4 and a cooking space door 6, with which a cooking space opening 8 of a cooking space 7, which is formed in a cooking space muffle 9 (oven), can be closed.
  • the cooking device 2 also contains one
  • the door sealing strand 10 can be fastened, for example, to the cooking space flange 4, as shown in FIG. 3, or to the cooking space door 6.
  • the cooking space flange 4 is part of the cooking device, which surrounds the cooking space opening 8 and is opposite the cooking space door 6 in the door closing position.
  • the following description relates to a cooking appliance 2 with the cooking chamber door 6 closed (closed position). It goes without saying that when the oven door 6 is open (Open position) the door seal strand 10 only the oven door 6 or only the
  • Cooking chamber flange 4 contacts, depending on whether the door seal strand 10 is attached to the cooking chamber door 6 or to the cooking chamber flange 4.
  • the cooking space flange 4 contains at least one heat decoupling slot 12 which extends around the cooking space opening 8 and which forms a hotter high-temperature part 4-1 of the cooking space flange 4 closer to the cooking space opening 8 and from a less hot, low-temperature part 4-2 of the cooking space flange opposite it and further away from the cooking space opening 8 4 thermally decoupled.
  • the high-temperature part 4-1 is exposed to higher temperatures (for example> 350 ° C.) than the low-temperature part 4-2 (for example ⁇ 280 ° C.) during operation of the cooking device 2.
  • the heat decoupling slot 12 can consist of a slot extending around the entire cooking space opening 8, or of a multiplicity of openings or individual slots which are arranged one after the other around the cooking space opening 8.
