Definitions

  • the present invention relates to a stove according to the preamble of claim 1.
  • Such a stove is known from DE 34 19 452 C, wherein at each of the two free ends of the seal or the sealing strip inside the seal a fastening element is fastened with a fastening hook by gluing, with which the aforementioned free ends in corresponding openings in Front flange of the oven muffle are locked with pre-tension.
  • a tensile force is exerted on both the horizontal and the vertical direction on the sealing piece and the fastening element fastened thereon, which is suspended in a lower corner region opening.
  • This prestressing in two mutually perpendicular directions also results in a smooth, undistorted sealing contour in the lower corner areas with a seal pressed onto the substrate.
  • the object of the present invention is to develop the known prior art in such a way that a satisfactory sealing in the lower corner regions is possible even without the two end section fastening elements.
  • the fastening hook has an inclined surface which preferably abuts the lower opening, via which the fastening hook is pulled into the opening due to the tensile force predetermined by the prestressing of the rubber seal in the vertical direction, as a result of which the seal on the flange or the door is pressed.
  • the fastening element In order to be able to specify the course of the seal through the fastening element, it has an arc-shaped rail part which is firmly connected to the sealing material, preferably glued.
  • the legs of the rail part In order to avoid accumulation on the inside of the door or the muffle of condensing vapors on the essentially horizontal end section of the seal, the legs of the rail part form an obtuse angle.
  • the seal is inclined slightly downwards and thus forms a kind of drainage channel for the unwanted liquid.
  • the two legs can also form an acute angle in such a way that the condensing vapor is collected and stored by the essentially horizontal end section of the seal and is evaporated in the furnace muffle during subsequent heating phases.
  • the opening has an insertion area and a holding area with the stop surface, which are arranged at a certain angle to one another.
  • the clear width of the insertion area is larger than the corresponding width of the fastening element. What is meant by this is that the width of the insertion area is correspondingly oversized in order in any case to offer sufficient space for the fastening element, regardless of the enamel layer thickness applied.
  • the inner wall of the opening has a curved pivot surface, via which the fastening element pivots from the inserted position into the holding position.
  • the lower opening is arranged in relation to the vertical course of the seal suspended at the top in such a way that the fastening element suspended in the lower opening Torque is exerted.
  • the fastening hook is screwed or pulled over its inclined surface like a screw into the lower opening. If there is a stop surface, the fastener almost automatically turns into the desired defined angular position.
  • the fastening hook has a hook extension next to the inclined surface. This also improves the excellent fit of the fastener in the lower opening.
  • a front flange 1 of a furnace muffle of a stove is shown schematically, which forms a fixed closure part and surrounds a cooking space opening 3.
  • a hinged or sliding oven door (not shown) serves as the movable closure part, which comes to rest on the front flange 1 with its peripheral inner surface in the closed position.
  • the door has fastening hooks with which it is held in the assembly openings 5 of the front flange 1 on the stove.
  • the sealing strip 9 is fastened to the front flange 1 by means of two identical upper fastening elements 11 and two identical lower fastening elements 13, which are all fastened in the corner regions of the substantially rectangular oven opening 3 in the manner described below.
  • the sealing strip 9 is cut open and the upper and lower fastening elements 11, 13 inserted therein and glued to the sealing material.
  • hook-shaped tabs protrude in a manner known per se from the contact surface of the seal, which are hung in corresponding, essentially circular upper fastening openings 15 of the front flange 1.
  • the lower fastening elements 13 are also glued accordingly to the sealing strip 9 and are hung in the lower fastening openings 17 described below (FIG. 3).
  • the lower fastening openings 17 are arranged approximately in a vertical extension in the corner region of the flange below the upper fastening openings 15 in the front flange 1. In this area, the sealing strip 9 extends obliquely downwards beyond the mounting opening 5, as a result of which condensing vapors within the sealing frame on the front flange 1 are conducted away from the mounting opening 5 by the seal 7.
  • the fastening element 13 has a fastening hook 21 with a dovetail-shaped hook end section 23 (FIGS. 2a, b, c).
  • the fastening hook 21 is rectangular bent by an arcuate or banana-shaped rail part 25.
  • the rail part 25 is designed as a flat plate, from which the fastening hook 21 is bent with the aid of two free cuts 26.
  • the two legs of the rail part 25 form an obtuse angle of approximately 140 °.
  • the rail part 25 is glued into the sealing strip 9 in a manner known per se, so that only the fastening hook 21 protrudes from the sealing material.
  • the likewise plate-shaped fastening hook 21 or its hook end section 23 has on its narrow sides opposite one another an inclined surface 27 and a hook extension 29.
  • the hook extension 29 ends in a kink 31, which is formed approximately at the middle height of the inclined surface 27.
  • a running surface 33 extends above the kink 31 on the narrow side of the plate-shaped fastening hook 21.
  • FIG. 3 a lower fastening opening 17 with an inserted lower fastening element 13 is viewed from the oven behind the front flange 1 (FIG. 1). Therefore, the fastening element 13 is mainly shown by the front flange 1 (not shown) in broken lines.
  • the tensile force exerted on the fastening element 13 by the tensile force predetermined by the seal 7, which is suspended by the corresponding upper fastening element 11, is represented by an arrow of forces 35.
  • the lower fastening opening 17 on the flange 1 is an elongated opening with an insertion region 37 and an adjoining holding region 39 widening the opening 17.
  • the inner wall of the fastening opening 17 is formed in the insertion region 37 by a rectilinear contact surface 41 which is in an opening bend 42 and a certain angle merges into a straight stop surface 43 of the holding area 39.
  • the angle is on the desired contact pressure the seal, the prevailing prestressing of the seal and the inclination of the inclined surface 27 of the fastening hook 21 in order to ensure an optimal hold of the fastening element 13 in the fastening opening 17.
  • the opening 17 is delimited by an arcuate pivot surface 45, over which the running surface 33 of the fastening hook 21 slides when the fastening element 13 is rotated clockwise from an insertion position in the insertion region 37 into a holding position in the holding region 39.
  • the inner wall of the fastening opening 17 is formed following the swivel surface 45 by a wall surface running parallel to the contact surface 41, the edge 47 of which on the side facing away from the seal 7 interacts with the fastening hook 21 when the seal 7 is assembled as follows.
  • the fastening hook 21 lies against the stop surface 43 in a defined angular position and the hook extension 29 engages with the others Stabilization behind the front flange 1.
  • the fastening hook 21 protrudes through the fastening opening 17 of the front flange 1 and claws with both the inclined surface 27 and the hook extension 29 in a defined manner.
