Definitions

  • the invention relates to a refrigerator, in particular a refrigerator or Freezer, with one between the opposite end faces the sealing frame of the refrigerated goods container and the side hinged to it Door arranged circumferential seal, comprising a plastic profile.
  • the seal which is preferably attached to the door, on a contact surface of the Sealing frame of the refrigerated goods container strikes at an angle of Is inclined at 90 ° to the outer surface of the refrigerated goods container.
  • the refrigerated goods container is preferably made from an inner container polymeric material and an outer container made of painted sheet metal are crimped accordingly in the edge area to accommodate the inner container. For the most part there is an insulation layer between the two components made of foamed PUR.
  • the door of the refrigerator is made in a comparable way, also with an inner door Made of preferably polymeric material, an outer door made of mostly painted sheet metal and insulation, preferably in the form of foamed PUR.
  • the hermetic seal of the gap between the door and the container becomes modern refrigerators and freezers with all-round, too rectangular sealing frames welded sealing profiles achieved with magnetic tapes in intended hollow chambers are equipped and mostly bellows-like Have walls to compensate for different sealing joint dimensions.
  • the invention is therefore based on the object of a refrigerator of the type mentioned Kind in such a way that the sealing gap differences to be compensated also taking into account strong temperature differences between indoor and the outside space are smaller, thus reducing the seal play of the seal can be.
  • the invention provides that the contact sealing surface, against which the seal rests - in the preferred case on the sealing frame of the refrigerated goods container - at an angle ⁇ ⁇ 90 ° to the outer surface of the refrigerated goods container is inclined, where appropriate in this inclined contact sealing surface a flat, the seal receiving groove can be molded.
  • the seal can of course also be glued or screwed on could, is preferably the mounting surface for the seal on the door or the Refrigerated goods container with at least one circumferential, one clamp fastening leg of the seal receiving groove, if necessary also two parallel grooves are provided for two clamping leg of the seal be, the clamp fastening leg in the simplest case a fir tree profile may have, which also takes into account manufacturing tolerances a secure clamp bracket is guaranteed.
  • the grooves in the corners of the sealing frame are intended in an embodiment of the invention rounded and the seal through a weld to a sealing ring be connected, what compared to the standard version angularly formed in the corners saves three welds, which is quite expensive in terms of cost Beat book.
  • the design and inclination of the contact sealing surface according to the invention is special intended for refrigerated cabinets, where the refrigerated goods container and the door consist of a non-magnetic, in particular polymeric material, the Seal in this case must necessarily be a compression seal.
  • the door of such a refrigerator can be locked in any manner is not the subject of the present application and should therefore also are not described in detail.
  • the inclination of the system sealing surface according to the invention thus has a double advantage, namely the possibility of retracting the seal, although it is thicker is as the sealing gap, and on the other hand reducing the necessary Oversizing the compression seal diameter due to the Door deflections.
  • the seal for such Refrigerating cabinet consisting of a polymeric material has at least one hollow chamber contain, in which, if necessary, an additional filling, in particular Foam filling or other materials with sufficient resilience can be introduced, wherein the seal made of one or more polymeric Materials with preferably different hardness can be made.
  • an absolutely play-free hinge is included with the help of the hinges that can be used for such refrigeration units for reasons of cost possible - can finally be provided in a further development of the invention that the seal, at least on the opening side opposite the hinge the door, is provided with a reinforced profile approach.
  • Fig. 1 shows the previously common design of sealing a door to the container a refrigerator, both the door 1 and the refrigerated goods container 2 double-skin from a plastic inner door 1a or a plastic inner container 2a and an outer door 1b or an outer container 2b made of painted sheet metal are built up, which are preferably foamed with foamed polyurethane or the like and are therefore very well insulated.
  • the edge 3b of the outer housing is bent over 90 ° over the inner housing and thus forms the system sealing surface at the same time 4, on which the seal 5 rests, with a in a pocket inserted magnetic bar 6 is provided.
  • FIG. 2 is one corresponding to FIG. 1 Section through a refrigerator according to the invention, in which both the refrigerated goods container 2, as well as the door 1 made of one or more non-magnetic, in particular polymeric materials.
  • a magnetic seal can of course not be used and one requires a compression seal, different in FIGS. 4 to 6 trained compression seals 5 'to 5' '' are shown.
  • Crucial for the structure according to the invention is independent of whether as in FIG. 2 the seal 5 ', 5 ", 5' '' is attached to the door 1, or as in Fig.
  • the inclination of the contact sealing surface 10 also has the advantage that the seal, whose diameter is definitely larger than that Sealing joint, not at the edge of the sealing frame with a 90 ° inclination of the contact sealing surface as with the prior art and trigger the closing movement can hinder. At the same time, this would not only damage the seal, there would even be a risk of being pulled out completely the seal from its holder on the door.
  • FIGS. 10 to 12 show round cord seals with hollow chambers 11 and 12, respectively in the case of the seal 5 '' 'in Fig. 6, the hollow chamber 11 with a foam 13 is filled out. Basically, this applies to all of these seals - this also applies to the Seals according to FIGS. 10 to 12 - that they are made of one or more polymeric Materials with preferably different hardnesses can be produced, the hollow chambers open or filled with foam inserts could be.
  • FIG. 7 and 8 show the corner formation of the refrigerator part 1 and 2, in which the groove 15 for the seal is formed, namely that in FIG. 7 is the conventional one Common case shown, in which the seal forms a rectangular frame while 8 shows the preferred case according to the invention, in which the groove in the corners are rounded so that the seal is only in one place at a time Sealing ring needs to be welded together while at the angular one Training four strips at the four corners need to be welded. This three additional welding processes make the design of the seal more expensive considerably.
  • the seal 5 is on the one hand with two Clamping attachment legs 14 for engaging two corresponding parallel ones spaced grooves 15 and on the other hand has an additional profile approach 18, which is specifically on the side of the hinge remote from the Door (left in Fig. 13) between the door and the sealing frame of the refrigerated goods container jammed and thus prevents the loaded door from lowering.
  • 11 and 12 show modifications of the sealing profile according to FIG. 10 with a division in several hollow chambers 12 on the one hand or with a training in which in the Hollow chamber 11 a foam cord 13 'is drawn.
  • the invention has Inclination of the system sealing surface also has the advantage that the Basically not similar to a round compression seal must run in over the inner edge of the sealing frame of the counterpart, which creates a significant risk of damage or destruction or tearing the seal out.
