Definitions

  • the present invention relates to a refrigerator, in particular a household refrigerator
  • the housing of household refrigerators conventionally comprise a body with a plastic deep-drawn inner container and an outer wall, which form a tongue and groove connection on a front frame of the body, and hinged to the body door , which in the closed position on the front frame is tight.
  • the front frame forms an inevitable weak spot in the thermal insulation of the refrigerator.
  • a refrigerator in which a partition wall between two compartments comprises a foam heat insulation wall and, between this and the subjects, each a lining of plastic material.
  • the liners each have a front edge which extends to the front edge of the heat insulating wall and in each of which a semicircular mounting groove is formed, which receives a heating tube.
  • the front edges of the liners are inserted in laterally open recesses of a cover that covers the leading edge of the heat insulation wall. If the heating tube does not remain in its full length in the semicircular groove, it can prevent the mating of the liners and the cover.
  • the object of the invention is to provide a refrigeration device, which allows a simpler and more rational installation of the heating tube.
  • the object is achieved in that, in a refrigerator with an inner container and an outer wall, an edge of the inner container forms a spring and the outer wall of a tongue and groove connection between the inner container and the outer wall, a heating tube is accommodated in a channel formed in the rim. and the heating tube is engaged in the channel.
  • the latching involves overcoming a supernatant until the heating tube reaches its target position in the channel, the same resistance then also counteracts an undesired escape of the heating tube from the channel and thus makes the use of adhesives superfluous.
  • the gutter can be deep drawn in the edge of the inner container, preferably in a same operation with the forming of side walls of the inner container.
  • the gutter may optionally be open to a front of the refrigerator or to a space extending between the inner container and the outer wall.
  • At least one of a pair of opposite sidewalls of the trough should have a first projection behind which the heating tube engages in the latched position.
  • a plane contacting the heating tube at a contact point between it and the one side wall and a plane contacting the heating tube at a contact point between it and the other side wall should cross each other in front of the groove at an angle of at least 10 °.
  • the greater this angle the greater is the resistance that must be overcome for snapping the heating tube into the groove or for releasing it. How large the angle is suitably chosen in each case, depends on the deformability of the inner container and the heating tube, that is, on their material and wall thickness from.
  • the other side wall may have a second projection, behind which the heating tube also engages in the latched position.
  • the projections may overlap one another in the longitudinal direction of the channel and thus form an entrance region of the channel which is narrower than the diameter of the heating tube and which has to be spread open in order to lock the heating tube into the channel.
  • the first projection, the second projection and a third projection of the one side wall can be offset from each other in the longitudinal direction of the channel; Then, in order to effect the locking of the heating tube in the channel, the elastic flexibility of the heating tube itself can be used, and a deformation of the channel is not essential.
  • the depth of the channel is smaller than the diameter of the heating tube, part of the heating tube must protrude from the channel. This part can be pressed against the outer wall in order to achieve efficient heat transfer between the heating tube and the outer wall.

  • Channel 4 and heating tube 10 touch each other here at three points 17, 18, 19, at the bottom of the channel 4 and at the two projections 14, 15. Planes 20, 21, the heating tube 10 and the side walls 12, 13 of the channel 4th at the points 18, 19, cross each other in a direction perpendicular to the sectional plane of Fig. 2 line 22, which lies outside the housing of the refrigerator in front of the channel 4 and the frame section 8.
  • the cross-sectional shape of the channel 4 shown in Fig. 2 in the form of a slightly flattened ellipse can be obtained in which the channel 4 is first deep-drawn in the form of a circular segment with a diameter slightly smaller than that of the heating tube 10 and is widened elastically by pressing the heating tube 10 ,
  • the elastic restoring force which acts on the heating tube 10 at the points 18, 19, keeps it firmly pressed against the point 17 at the bottom of the channel 4 and prevents unwanted Escape of the heating tube 10 from the channel 4 during assembly of the refrigerator.

  • the edge 3 is elastically clamped between side walls 23, 24 of the groove 9, the cross-section of the groove 9 widening towards a bottom 25 ensuring that the edge 3 is drawn into the groove 9 after overcoming a bottleneck at the entrance of the groove 9 and strikes the ground 25.
  • a region 26 of the heating tube 5 projecting from the channel 4 is in direct contact with the front side wall 23 and thus ensures efficient heat transfer to the frame section 8.
  • Fig. 3 shows a plan view from the front of a part of the edge 3, in which it can be seen that the heating tube 10 engages in the locked position behind the projections 14, 15 on both sides of the groove 4 in the straight line shown in FIG.
  • the projections 14, 15 are here elongated in the longitudinal direction of the channel 4, but do not extend over the entire length, in particular curved portions 27 of the channel 4 at the corners of the edge 3 (see Fig. 1) of the projections 14, 15 should be free be.
  • Fig. 4 shows a variant in which only one side of the channel 4, a projection is formed.
  • a projection 15 is provided only on the outer side wall 13;
  • the one projection 15 is sufficient to define at the contact points 18, 19 between the heating tube 5 and the side walls 12, 13 tangential planes 20, 21, which intersect in front of the inner container 3 at 22 and so for the locking of the heating tube 10 in the channel 4 worry.
  • the angle a, under which the planes 20, 21 intersect, in the case of Fig. 4 is smaller than in Fig. 2, and accordingly here is the force at given dimensions of the edge 3 and the heating tube 10 for locking the Heating tube 10 or to release Its latching is required, less than in the case of Fig. 2.
  • an angle of ⁇ of 10 ° should not be fallen below in the rule.
  • FIGS. 6 and 7 show a section and a plan view of the edge 3 according to a third embodiment of the invention.
  • the projections 14, 15 on the two side walls 12, 13 are here less elongated in the longitudinal direction of the channel 4 than in the first and second embodiment and are each distributed alternately on the inner side wall 12 and the outer side wall 13. Again, a locking of the heating tube 10 in the channel 4 under elastic deformation of the channel 4 is possible, but at the same time, the flexibility of the heating tube 10 can be exploited here, in which the heating tube 10 to a projection such as 14 on the side wall 12 to pass, is deflected into a gap 29 between projections 15 of the opposite side wall 13 into it.
  • the width b of the inlet region is smaller than the diameter of the heating tube 5 as measured in the transverse direction of the channel 4, but if in each case the distance d between a projection and a region of the opposite side wall directly opposite this projection is at least as large as the diameter of the heating tube 5, a locking is still possible even if the edge 3 itself is not deformable.
  • a passage is needed in the edge 3, which connects the laid in the channel 4 heating tube 10 with in the space between one of the side walls 2 of the inner container 1 and an opposite wall panel 7 extending supply and discharge lines. This passage must be carefully sealed before the insulating layer surrounding the inner container 1 is formed by foaming the intermediate space.
  • FIG. 8 in a cross section analogous to FIG. 2.

  • the side wall 24 outside the sectional plane of FIG. 8
  • the side wall 24 has a gap through which a feed line or discharge line 31 (integral with the heating tube 10) runs. Since the edge 3 of the inner container 1 has no opening at this point, no elaborate sealing is required to prevent the penetration of insulating foam into the groove 9 and through this to the front of the body.
  • the cross section of the channel 4 is the same as in Fig. 2.
  • Fig. 9 shows in a cross-section analogous to Fig. 2, a fifth embodiment of the invention, in which the channel 4, as in the case of Fig. 8 to the gap 30 is open.
  • the groove 4 is not formed by deep drawing, but it is the fact that the frame 3, since it substantially does not participate in the stretching of the central part of the board during deep drawing of the side walls 2 and the rear wall on finished inner container has a higher wall thickness than this.
