Definitions

  • the present invention relates to a circulating air refrigeration device, also referred to as a no-frost refrigeration device, and a method for its assembly.
  • a circulating air refrigeration device also referred to as a no-frost refrigeration device
  • an evaporator is usually housed in a chamber which is separated by an intermediate wall of a storage area in the interior of the device housing.
  • the evaporator of such a refrigerator outside the housing with other parts such as the aforementioned partition, sauceleitblechen, air guide plates or the like.
  • these other components Pre-assembled to an assembly, which is then inserted as a whole in the refrigerator housing, these other components, in the mounted state hide the evaporator, be attached to the housing.
  • the object of the invention is to provide a circulating air refrigeration appliance and a mounting method therefor, which allow to reduce such scattering.
  • the object is achieved in that in a circulating air refrigeration device with a housing which surrounds at least one storage area and an evaporator chamber, in which an evaporator is housed, protrude at an evaporator chamber bounding the inner wall of the housing projections on which the evaporator is latched.
  • the direct attachment of the evaporator to the projections reduces the scattering in the evaporator position; moreover, since the latched evaporator is not hidden behind other parts at the moment of its installation, it is possible to visually inspect its placement and, if necessary, correct it.
  • a pair of pliers is formed at the tip of the projections, which surrounds a tube of the evaporator.
  • An insertion opening for the pipe on the pliers is preferably remote from the inner wall supporting the projection, so that the evaporator can be snapped into the pliers in a movement directed towards the inner wall. In such a latching movement, the projections are substantially loaded only on pressure, torques that could excessively burden the connection of the projections with the inner wall carrying them are avoided.
  • a stem of the protrusion is preferably formed by at least two struts extending from the forceps to the inner wall and spaced apart by a gap.
  • This design makes it possible to carry out the projections easily and with a small cross-sectional area and yet stable, even against torques acting thereon. Further, the division into a plurality of struts allows rapid heating of the protrusions when the evaporator is defrosted, so that even the protrusions are reliably removed from ice during defrosting, even if they consist of a poorer heat-conducting material than the evaporator, in particular of a plastic.
  • the projections are preferably molded parts, which are each anchored in an opening of the inner wall. This makes it possible to form the inner wall in a known and well-controlled manner by deep drawing.
  • the mold parts preferably each have an engaging in the opening of the inner wall head portion which is undercut two flanks to engage behind the edge of the opening at two locations, and which has a gap between the two flanks.
  • the gap makes it easier for the two flanks to move elastically toward one another when the head section is fitted in the opening, be it when the head section is pressed into the opening or when the head section already inserted into the opening is rotated.
  • the invention is particularly advantageously applicable to a finned evaporator, but is generally suitable for any type of evaporator having tubes that can be gripped by a pair of pliers.
  • a partition between storage area and evaporator chamber is preferably mounted independently of the evaporator in the housing. This makes it possible to To remedy a fault by removing the partition to expose the evaporator chamber, but leave the evaporator in place.
  • the object is further achieved by a method for mounting a circulating air refrigeration appliance, in particular a device as described above, in which first an evaporator is latched to protruding from an inner wall of a housing of the device protrusions and then a partition wall is mounted on the inner wall, which is the interior of the housing divided into a storage area and an evaporator chamber.
  • the protrusions are preferably created by anchoring shaped parts in an opening of the inner wall.
  • Figure 1 is a schematic vertical section through the upper portion of the body of a refrigeration device according to the invention.
  • Fig. 2 is a perspective view of a support member used for mounting the evaporator in the refrigerator of FIG. 1.
  • Fig. 1 shows a schematic section through the upper region of the body 1 of a refrigeration device.
  • the body 1 has in a conventional manner a solid outer skin made of sheet metal, which is connected at a front of the body sealed to a deep-drawn plastic container, which forms an inner wall 2 of the body.
  • the space between outer skin and inner wall 2 is substantially filled with insulating foam material.
  • carrier parts 3 are latched, two of which can be seen in the figure.
  • the carrier parts 3 are formed from a solid plastic such as POM and form at their end remote from the inner wall 2 each end a pair of pliers with two jaws 4, which are sufficiently elastically deformable to a tube 5 of a finned evaporator. 6 - A -
  • the evaporator has a plurality of parallel lamellae 7, one of which can be seen in the figure.
  • the lamellae 7 are sheets of substantially rectangular outline with a plurality of open-edged recesses through which the tube 5 runs in serpentine lines.
  • the support members 3 anchor the evaporator 6 fixed to the ceiling of the inner container; Therefore, it requires no further support by a mounted below partition 8, which delimits an evaporator receiving chamber 9 from an underlying storage area 10 for refrigerated goods.
  • a fan 11 is further accommodated, which sucks air from an inlet opening 12 of the evaporator chamber 9 through the evaporator 6 and ejects via a to the rear wall of the body 1 adjacent outlet opening 13 back into the storage area 10.
  • Fig. 2 shows a perspective view of one of the support members 3.
  • the integrally molded plastic carrier part 3 has a two-part base plate 15 which rests in the assembled state on the underside of the ceiling of the inner wall forming container.
  • a serving for anchoring to the ceiling head portion 16 has two opposite flanks 17a, 17b, each upwardly converging inclined surfaces 18 and at the bottom of the inclined surfaces 18 each have an undercut 19 whose height corresponds to the thickness of the inner container.
  • a gap 20 which separates the two parts of the base plate 15 extends into the head portion 16 and facilitates the flanks 17 to move towards each other when the head portion 16 is pressed into an opening of the inner container and elastic again move apart as soon as the inclined surfaces 18 have passed through the opening, so that in the assembled state of the inner container in the undercuts 19 locked.
  • Two of the parts of the base plate 15 downwardly extending struts 21 carry a circular arc-shaped pliers 22, wherein the ends of the arc form the jaws 4.
  • the pliers have a downwardly directed opening 23, in which the brought up from below tube 5 of the evaporator 6 (not shown in Fig. 2) can be pressed.
  • the temporary deformation of the forceps 22 during pressing leads to a bending stress of the struts 21, which may cause the two parts of the Base plate 15 temporarily move towards each other. But since at the same time the base plate 15 is pressed against the inner container, thereby the anchoring of the support member 3 is not affected on the inner container.
  • the two spaced apart by the gap 20 struts 21 give the support member 3 a great security against kinking with little material use.
  • the cross-sectional area of the struts 21 can be kept significantly smaller than that of a comparable resilient individual strut. This saves on the one hand material and costs, on the other hand allows rapid heating of the support member 3, when the evaporator is defrosted, so that the support member 3 is reliably defrosted despite the poor compared to the metal of the evaporator 6 conductivity of its plastic material.
  • different types of carrier parts 3 can be used, which differ in the length of their struts 21.
  • the width b of the struts 21 and the pliers 22 is significantly smaller than the distance of the parallel slats 7 of the evaporator 6 from each other with about 5 mm to the pliers 22 can easily and with a certain play in the lateral direction between the slats 7 to introduce ,
  • the head portion 16 is mountable not only by being press-fitted into an opening of the inner wall 2 but also in the manner of a bayonet mechanism by first being inserted into an elongated opening of the inner container without deformation until the base plate 15 contacts the inner container, and then 90 ° Is rotated so that the longitudinal edges of the elongated hole engage in the undercuts 19.
