Definitions

  • the invention relates to an arrangement for sealing a door closing an oven muffle with a sealing profile made of heat-resistant, elastomeric material, in particular silicone rubber, the sealing profile enclosing the area of the charging opening of the oven at least on three sides and in the corner regions on the door or on the muffle frame under tension is releasably attached.
  • a corresponding seal is known from US-A-3 131 684, which essentially consists of a U-profile with a sealing lip attached to one leg, bent back and a cylindrical thickening on the other leg.
  • a circumferential gap with a bulge at the gap foot is provided, which surrounds the oven muffle on all four sides and in which the seal is clamped over its entire length with its cylindrical, thickened end.
  • Such a seal and in particular your bracket also requires a high level of design and manufacturing effort.
  • the oven door has straight incisions running in sections, the lateral boundaries of which are bent up and comprise a T-shaped shoulder on the lower leg of a basically L-shaped sealing profile. Because of the complicated cross-sectional shape, such a sealing profile is relatively difficult to manufacture and insert into the corresponding incisions in the door. In addition, with such a mounting of the profile, a pretension in the longitudinal direction thereof can only be achieved with additional aids.
  • the present invention has for its object to provide an arrangement for sealing an oven door, in which an easy-to-manufacture sealing profile can be held safely and under tension in the oven door or in the muffle frame without additional aids.
  • the sealing profile has an approximately L-shaped cross section with an incision in one of the free legs and from its free end and that the sealing profile obtained as a straight profile strand for fastening in the corner regions with its incision in tongues bent sheet metal incisions of the oven door or the muffle frame is jammed.
  • the leg provided with the cut is expediently divided into an inner profile web and an outer profile web, the inner profile web being longer than the outer profile web and bent outwards at its end.
  • the incisions in the corners of the oven door or the muffle frame can be designed in the shape of a quarter circle and bent up in such a way that the free end of the curved incisions runs parallel to the level of the door or the muffle frame and the sealing profile is guided around this incision in the corresponding arc.
  • extruded profile strands can be used continuously, which are easily guided around the sheet metal incisions and have a secure fit without additional fasteners and ensure an optimal seal.
  • the sealing profile 1 has an approximately L-shaped cross section.
  • the upward leg 2 is slightly arched inwards so that it is easier to put on the muffle flange of the oven later.
  • the foot part 3 of the sealing profile 1, which extends horizontally to the right in the drawing, is provided with a horizontally ending incision 4.
  • the profile web 5 running above this incision 4 is somewhat longer than the profile web 6 lying below the incision 4 and is bent downward at its free end 7 such that it roughly encompasses the profile web 6 while leaving the incision 4 free.
  • FIG. 2 shows a view of the inside of the door in the area of the upper left corner, since this section is sufficient to explain the mode of operation.
  • FIG. 3 which shows a cross section corresponding to the section line 111-111 according to FIG. 2
  • the inside of the oven door 10 has an approximately quarter-circle-shaped incision 11 in the corner region with short radial cuts 12 and 13 at the ends of the Incision 11, so that there is an exposed, quarter-circle-shaped tongue 14.
  • This tongue 14 is now bent up in accordance with the cross section in FIG free end 15 again runs parallel to the plane of door 10. This results in a free gap in height and width between the outer cut edge 16 of the incision 11 and the inner edge 15.
  • the sealing profile 1 with its incision 4 is pushed over the free end 15 of the tongue 14 and bent according to the arc of the tongue 14, so that the profile 1 on the inside of the door 10 then a course corresponding to dash-dotted line 17 takes.
  • the front corner 18 then lies above the cut edge 16 on the inside of the door 10, while the lower profile web 6 and the upper profile web 5 enclose the tongue 14.
  • the free end 7 of the upper profile web 5 lies flat and sealingly on the tongue 14 in accordance with the curvature thereof.
  • the sealing profile 1 can then be fixed at the other corners of the door in the same way to corresponding incisions and guided around these corners, so that there is a closed sealing frame.
