Definitions

  • the invention relates to an oven seal for sealing the gap between the door and oven muffle of an oven, the seal being made of heat-resistant, elastic material and moving the loading opening of the oven muffle as a three- or four-sided sealing frame, and the sealing frame being provided with fastening means via which it is fixed on the muffle flange or on the inside of the door with a sealing effect.
  • Such oven seals are known in a variety of embodiments.
  • DE 32 00 652 C3 results in a four-sided seal which consists of stretched frame parts which are mitred in the corner areas.
  • the frame parts are hollow chamber profiles and rectangular shaped metallic tabs are inserted in the corner areas, which have a hook on the corner punched out on three sides of the bracket body and bent downwards.
  • the two partial flaps are glued in the hollow chambers of the sealing profiles pushed together by miter.
  • the four corner areas of the sealing profiles are assembled into a rectangular sealing frame, in which the hooks protrude from the sealing plane in the mitred corners. Special through openings can be punched out for these hooks in the miter areas of the individual corners.
  • the elastic sealing frame is then hooked into openings on the door or on the oven muffle via the hooks, whereby a certain pre-tensioning of the frame areas of the seal is intended to prevent harmful wave formation.
  • oven seal is known from DE 30 47 380 A1, which likewise has fastening means arranged in the corner regions, by means of which the seal is fastened to the muffle flange or to the inside of the door.
  • these fastening means can be metal hooks connected to the seal and with hook-like ends projecting beyond the seal. These hooks have at least one elongated extension, which is fixed inside the seal designed as a hollow profile by, for example, gluing.
  • elastic locking knobs molded onto the seal can also serve as connecting means, which in turn can be pressed into and locked into locking openings in the muffle flange or the inside of the door.
  • a latching foot serving as a fastening means is formed longitudinally on the underside of the seal, which protrudes into a circumferential bead on the muffle flange or on the inside of the door and is mainly pressed into a receiving space in the corner areas, which is bent by bending opposite edge areas Groove is formed while maintaining a continuous slot opening.
  • the elaborate manufacture of individual shapes with different profile dimensions can be dispensed with when producing the sealing profile.
  • the profile can rather be generated regardless of length in the simple extrusion process and then cut to the length required for the production of the sealing frame.
  • the further advantage of the latching foot extending over the entire length of the seal is that this latching foot can be pressed into a receptacle at any point or can be inserted in a latching manner.
  • a circumferential bead is first inserted on the inside of the door or on the muffle flange. This process takes place without cuts in the sheet metal cover. The incisions are only made where the seal actually has to be held, i.e. primarily in corner areas. Here, a straight cut is made at the base of the bead, e.g. can follow the curve of the corner. After this incision process, the opposite edge regions of the bead formed in this way are bent open and a slot opening is created on the free edges which should correspond to the thickness dimension of the latching foot.
  • the latching foot is then inserted and fixed in this slot opening.
  • the latching foot advantageously has an arrowhead as a latching element at its free end, which is connected to the underside of the seal via a foot region, the width of this foot region corresponding to the clear width of the slot opening.
  • the main advantage of the oven seal according to the invention is seen in the fact that the circumferential latching foot extends over its entire length into the circumferential bead on the muffle flange and on the inside of the door.
  • This latching foot only performs a latching function in the receiving spaces which are produced by bending opposite edge regions of the bead to form a continuous slot opening.
  • the snap-in foot has no function in the circumferential groove.
  • an assembly flag can be formed on the arrowhead of the latching foot.
  • the seal can be pressed into the profile receptacle from above as well as drawn in from below using this assembly flag. This retraction can take place, for example, by pliers-like working means, by means of which the arrowhead of the latching foot is pulled through from below through the slot opening in the profile holder. In this way, the assembly of the seal on the inside of the door or on the muffle flange can be facilitated.
  • Fig. 1 shows the seal 1 with the sealing lug 11, the sealing body 12, the latching foot 13 and the arrow tip 14.
  • the latching foot 13 can have a continuous hollow chamber 130 in its foot region 131, into which a mechanical aid, not shown in the drawing, can be used Gluing two free seal ends can be used.
  • the arrow tip 14 projects beyond the cross section of the foot area 131 with the arrow beads 141, 142. Instead of the arrow tip 14 with the two arrow beads 141, 142, only a left arrow bead 141 or a right arrow bead 142 can be used, if necessary, on the free end of the foot area 131 one-sided locking element can be used.
  • the projecting cross-sectional areas 121, 122 are formed as sealing lips, which in the locked state are sealingly supported on the outside 21 of the inside of the door or the muffle flange 2.
  • the seal 1 is connected to the inside of the door or the muffle flange 2 in such a way that the latching foot 13 with the arrow tip 14 is introduced into the clear receiving space 23 of the surrounding bead 24 via the continuous slot opening 22. In the profile shape shown, this is introduced by pressing in in the direction of the arrow from above. After pressing in, the projecting cross-sectional areas 121, 122 of the sealing body 12 engage behind the opposite edge areas 25, 26, which have been created by cutting and bending open partial areas of the groove 24 and producing the continuous slot opening 22. In this way, the seal 1 is firmly anchored to the inside of the door or the muffle flange 2.
  • FIG. 2 shows the top view of a corner area of the inside of the door or of the muffle flange 2 with the partial areas of the circumferential groove 24 and the receiving spaces 23 created by cutting and providing opposite edge areas 25, 26.
  • bent edge regions 25, 26 are arranged directly in the corner, but can also be located on the extended sides of the inside of the door or the muffle flange 2 in the case of larger dimensions.
  • Fig. 3 shows a changed profile shape of the seal 1 with the mounting tab 15 at the free end of the arrow tip 14.
  • the hollow chamber 130 in the foot region 131 of the Locking foot 13 is missing. This hollow chamber 130 is not a mandatory requirement, since the free ends of the sealing profile 1 can also be connected to one another without them.
