Definitions

  • the present invention relates to a connection of the oven and oven support frame according to the preamble of claim 1.
  • a seal is provided around the oven opening, which seals against the closed oven door.
  • Such a seal is, according to a first technique, detached from the oven / oven support frame connection, or, according to a second fastening technique, a connection of the oven and oven support frame is used to provide the seal mentioned.
  • Fig. 1a shows schematically a plan view of the oven attached to the receiving frame, while Fig. 1b shows a cross section along line I-I of Fig. 1a.
  • the oven space 1 is defined by the oven 3, which, bent outwards, which forms an oven frame 5.
  • the outermost frame area 7, as can be seen in particular in FIG. 1b, is bent back in an S-shape.
  • the receiving space 9 with a correspondingly bent-up receiving frame 11 is bent in at the edges, as can be seen at 13.
  • a sealing profile 15 is clamped in the gap 17 defined between the bent-in oven part 13 and the S-shaped part of the oven frame 5 and engages behind the bent part 13 of the receiving frame 11.
  • the sealing profile 15 lies close to the oven door, shown in broken lines at 19 when it is closed.
  • the provision of a gap between an oven and oven support frame has the essential advantage of thermal insulation between the oven and connecting parts.
  • this gap is used at the same time for anchoring the necessary seal and thereby utilizing the thermal-insulating properties of the sealing materials usually used, such as silicone rubber.
  • the present invention is based on the above-mentioned second technique, implemented in known ovens according to the aforementioned FIGS. 1a and 1b.
  • the present invention aims to overcome these disadvantages, which is achieved in a connection of the type mentioned in its execution according to the characterizing part of claim 1.
  • the oven and oven holder are mechanically connected in the front area in that opposite tabs, each on the two frames, bridge the gap and are detachably connected.
  • connection mentioned is completed with a seal which is anchored in the gap essentially along its entire length.
  • the seal preferably has a profile with a sealing part which projects outwards from the aforementioned frames and with a receiving part in the gap, the mentioned receiving part being less elastic, i.e. to facilitate insertion of the seal into the gap. is harder than at least parts of the sealing section, namely in particular parts that come into contact with the door.
  • the sealing profile subsequent to the receiving part, has a rear grip part which engages behind the edges of the bent frame parts.
  • the rear grip portion is preferably made harder or less elastic than that mentioned receiving section, which facilitates their passage through the gap.
  • the seal is preferably made of silicone rubber, this for normal temperature furnaces up to approx. 300 o C, or of a glass fiber fabric hose for higher temperature ranges of, for example, 500 o C.
  • the last-mentioned seal preferably comprises, on the head side, a wire mesh reinforcement to form the sealing part, a stiffening insert for Formation of the receiving part and preferably a wire insert to form the rear grip part.
  • the oven frame 5 of the oven 3 is essentially bent back at a right angle, as is the mounting frame 11.
  • the oven frame side and the mounting frame side are thus formed with two substantially parallel, opposite edge parts 5a and 11a, which between them the gap 17, essentially perpendicular to the frame surfaces 5, 11.
  • the gap 17 extends around the entire oven opening, with the exception of a few, for example two anchoring sections 23.
  • the parts 5a and 11a are cut in pairs, so that the tabs 21 defined in each case between cuts the respective frame, also opposite one another, can be bent into the gap 17, where, for example by means of screws, the oven frame and the receiving frame are connected to these few narrow anchoring sections 23.
  • FIG. 3 shows, again in cross-sectional representation, the gap area of the arrangement according to the invention according to FIG. 2 with inserted seal 25.
  • the profile of the seal has a sealing section 27, designed as a hollow profile, a receiving part 29, which is received in the gap 17, and a rear grip section 31.
  • the hardness of the material of the receiving section 29 and of the rear grip section 31 is chosen to be greater than that of the material on the sealing section 27.
  • the silicone material has a hardness of 80S on the receiving section 29 and the rear grip section 31, on the other hand a hardness of only 50S on the sealing section 27 and 31 respectively.
  • 4 to 8 show further possible configurations of the sealing profile used according to the invention. 4 and 5, in which again the same reference numerals are used, do not require any further explanations, apart from the interaction of the receiving part 29a and the rear engagement part 31b in the embodiment according to FIG. 5.
  • the receiving part 29a is so narrow that it can be accommodated in the gap 17 with some play.
  • a secure anchoring of the seal 25 is ensured by the conically tapering rear grip portion 31b, on which a barbed profile 32 is molded.
  • increasing pressure increasingly broader parts of the barb-reinforced rear gripping part 31b are brought into engagement with the edges of the gap-defining pipe or muffle frame parts, so that when the seal is released, a tension in the one entered in FIG. 5 with x Direction takes place, namely on the edges mentioned on the one hand and on the frames 5 and 11 of FIG. 2 each as abutment surfaces.
  • connection according to the invention also allows flexible insertion of either silicone rubber seals of the type shown in FIGS. 3 to 5 for thermal Load ranges up to, for example, 300 o C, but also allow for high thermal loads, for example at 500 o C, to insert seals that are highly resistant to high temperatures, such as those made of glass fiber fabric hose, without further changes, FIGS. 6 to 8.
  • FIG. 6 shows a seal of the last-mentioned type which, as can be readily seen, can be inserted into the gap 17 without any problems. It is formed by a glass fiber fabric hose 34.
  • the sealing section 27 c is reinforced with a metal wire mesh 36, which fabric is stitched in the areas 37.
  • the hose 34 then forms the receiving part 39, where a reinforcing insert, such as a steel strip insert 41, is inserted.
  • the rear grip part of the seal, 43 is formed by inserting a wire 46.
  • barbs 48 are formed on the receiving part 39, acting as rear engaging parts, or, according to FIG. 8, the receiving part is formed by the one leg of individual hooks 50, which also form the respective rear engaging parts.
  • FIG. 9a shows a seal 60 made of silicone rubber which is particularly preferred today. It in turn comprises a hook-shaped rear gripping section 62, a receiving section 64 and a sealing section 66. Preferably, the receiving section 64 and rear gripping section 62 are again harder than the sealing section 66. Two side sealing tabs 68 are formed on the sealing section, which, as can be seen in FIG. 9b, with the sealing profile in place, fit snugly against the frame surfaces 5 or 11.
  • the inward bend 70 on the sealing section 66 continues a predetermined kink when creating the seal to the oven door 19 as shown in FIG. 1b.
