Definitions

  • the invention relates to a refrigerated cabinet with a circumferential mitred sealing frame in the corner regions, in particular for freezers, consisting of a refrigerated goods container and a closet, in the edge regions of which the sealing frame is arranged and in the closed state closes the opening of the refrigerated goods container airtight, the Sealing bellows of the sealing frame has means for accelerated pressure equalization when opening and closing the closure lid.
  • German patent 1 601 171 discloses a sealing frame for a refrigerated cabinet consisting of a profile seal, which has an air passage in the profile seal which is connected to the outside air and which is covered against the interior of the freezer by an additional lip seal. With this arrangement it is achieved that with the closing of the freezer door a rapid pressure equalization between the air in the refrigerator and the outside air surrounding the refrigerator can take place.
  • the air outlet itself is designed as a through hole in the profile seal.
  • a further profile seal arrangement for refrigerated cabinets in which a deliberately induced constriction of the breathing height of the sealing frame is brought about in order to reduce the opening forces in refrigerated cabinet doors.
  • the sealing frame is partially with a tape that z. B. can be an adhesive tape, constricted.
  • the effect of this measure is that when lifting the refrigerator lid, d. H. when the opening force is applied at the points of the constriction, the air balance between the interior of the refrigerator and the outside air can occur earlier, so that the force required for opening is reduced.
  • the disadvantage of this measure is to be seen in the fact that the constrictions have to be made subsequently by wrapping the sealing frame with the adhesive tape at the places provided for this purpose.
  • the constrictions can be produced, for example, by additional work steps if the sealing frame is already connected to one another in the corner regions. Then one or more such radial constrictions are made at a point to be determined above the longitudinal extent of the sealing frame by wrapping with the adhesive tape.
  • the constrictions can also be on the unconnected profile sealing parts. are produced, after which the individual profile sealing parts are then built up in the corner areas by a corresponding connection to the sealing frame.
  • the object of the invention is seen primarily in the creation of a sealing frame for a refrigerated cabinet which receives the means for accelerated pressure equalization in the areas of the weld seams without additional work steps during the assembly of the frame parts to form the sealing frame.
  • the height of the sealing bellows in the miter corners in the unloaded state is reduced to one, which is up to 2 mm above the gap height between the refrigerated goods container and the closed lid.
  • the reduction in cross-section advantageously takes place when the profile individual parts sweat into the sealing frame.
  • the sealing frame according to the invention takes advantage of the possibility, when joining the sealing frame parts in the corner areas, to permanently introduce the reduction in cross section in a single work step, which is necessary for rapid pressure compensation when the refrigerator lid is opened.
  • the invention also takes advantage of the fact that when the individual profile lengths of the sealing frame are joined in the miter corner areas by the application of welding heat, the plastic material used to produce the sealing profile is plasticized, which can not only be used to connect the individual profile parts, but simultaneously for permanent lowering of the cross-section of the profile seal in the connection area of the mitred corners.
  • the plastic material is pressed into the profile seal in these areas and remains in this pressed state due to cooling.
  • the corner welding and the synchronously reducing cross-section can be adjusted so that a breathing movement of the sealing frame is still possible in the corner area with reduced cross-section.
  • this distance can be adjusted up to 2 mm and depends on the weight of the refrigerator lid and the size of the refrigerator itself. In any case, it is essential that this distance information maintains a reduced sealing area which it is easy to overcome when the refrigerator lid is opened, before pressure equalization takes place.
  • the profile seal 1 is shown, which consists of the profile foot 2 and the bellows 3.
  • the profile foot 2 consists of the latching parts 21, 22, which ensure a secure fit of the sealing frame on the closure cover.
  • the sealing bellows 3 consists in the illustration shown of a three-part hollow profile. This three-way division takes place through the blocking walls 31, 32, 33 formed in the sealing bellows 3, which together with the outer walls 34, 35, 36 of the sealing bellows 3 form the partial hollow chambers 37, 38, 39.
  • FIG. 2 shows the profile seal according to FIG. 1 in its working areas.
  • 1 shows the profile seal in its extrusion state
  • FIG. 2 shows the state of the seal as it results after insertion into the sealing cap as a permanent deformation due to the working pressures occurring.
  • the outer walls 34 and 36 of the sealing bellows have been rounded in the shape of the permanent deformation shown in dashed lines and pushed outwards.
  • the inner webs 31, 32 have followed this movement outwards. They now form with the inner web 33 a flattened Y shape compared to the illustration in FIG. 1.
  • the outer wall 35 of the sealing bellows 3 has also flattened in its bulges.
  • FIG. 2 shows, compared to the permanent deformation of the profile seal in the dashed version, the position of the highest compression when the closure lid rests on the refrigerated goods container.
  • the outer walls 34, 36 of the sealing bellows 3 are pressed even further outward, the inner webs 31, 32 are positioned almost at right angles to the inner web 33 and the outer wall 35 bears approximately on the inner webs 31, 32. It is easy to see from this illustration that a further compression of the sealing bellows 3 is no longer possible, since the inner web 33 and the inner webs 31, 32 articulated thereon would oppose this.
  • FIG. 3 shows the profile seal in the welded corner areas.
  • the end region of the pressing according to FIG. 2 has not yet been reached; H. the outer wall 35 of the sealing bellows 3 still protrudes slightly from the inner webs 31, 32.
  • the difference between the final pressing of the profile seal shown in FIG. 2 and the distance between the corner weld shown in FIG. 3 shows the possibility of pressing in the welded corner areas.
