Definitions

• the present invention relates to a refrigerator with an interior divided into several compartments, in particular a fridge-freezer combination device, in which a freezer compartment is equipped with a pivotable flap, which makes it possible to separate the freezer compartment from the rest of the interior in a largely airtight manner.
• Such a refrigerator is known from DE 36 13 439 A1.
• a heat-insulating partition extends between the freezer compartment and the normal refrigerator compartment, which occupies the rest of the interior of the refrigerator, and the flap is pivotally mounted on trunnions which are mounted on the front edge of this partition.
• These journals can be subjected to considerable tensile forces, particularly when the flap is open, which require robust anchoring to the partition.
• the partition itself is generally not very resilient, since, like the housing of the refrigerator, it is designed as a rather thin-walled hollow body filled with insulating foam material.
• a reinforcement plate In order to anchor the trunnions securely and tear-free, a reinforcement plate must be provided in the interior of the partition, which has the threaded holes in which the screws can engage. Matching these holes, holes must be created in the outer shell of the partition wall, which coincide exactly with those of the reinforcement plate, and care must be taken to ensure that when the partition wall is filled with the insulating foam material, it cannot escape through the holes.
• the object of the invention is to provide a refrigeration device with an interior divided into several compartments, in which at least one compartment can be closed with a flap, which enables the flap to be installed easily and yet reliably.
• a refrigerator with the features of claim 1.
• forces acting on the flap are introduced into this wall parallel to its surface, ie in a direction in which one comparatively thin wall has a considerable load-bearing capacity.
• the trunnions are each inserted into a recess in the wall in the direction of the axis. It is thus possible to manufacture the bearing journals from one material and with a thickness that can be selected regardless of the properties of the wall. This is particularly expedient if the wall that receives the trunnions is a deep-drawn inner container of a refrigerator.
• the hollow, in particular cup-shaped bearing journals for reasons of material saving, are preferably introduced with an open side of the cup into the recesses in order to avoid the ingress of dirt.
• the trunnions are each provided with a circumferential rim that defines a stop up to which the trunnions can be inserted into the recesses in the wall.
• the flap has a recess on each of the two flanks of the housing facing the bearing journal, into which the journal engages in order to form an articulated connection.
• the cutouts are each connected with a groove that is open toward the edge of the side flank.
• these can each be recessed more deeply into the side flank than the grooves, or they can be slightly wider than the grooves.
• the grooves are preferably each open to a narrow side of the side flanks.
• the narrow side is the lower side flank of the flap. This ensures that the flap can essentially only be dismantled in its open position and the flap cannot be pressed out of its anchoring when it is closed by the goods protruding from the compartment behind it.
• each groove is closer to an outer side of the flap than that which is connected to the same groove and forms the hinge Deepening.
• the groove also slopes downward from the recess toward its open end in the open position of the flap, so that a horizontal pull on the flap is not sufficient to release it from the joint, but an upward force must be added.
• the bearing pins each have a recess at their tip, into which a projection of a side flank of the flap engages.
• the recess is preferably provided with an edge opening through which the projection can be moved sideways out of the recess.
• the cross section of the projection and the orientation of the edge opening are expediently chosen such that the projection is only able to pass the edge opening when the flap is in the open position.
• Figure 1 is a view of a refrigerator with a remote freezer, to which the present invention is applicable.
• FIG. 2 shows a perspective view of a hinge structure for the freezer compartment door of the refrigeration device from FIG. 1;
• Fig. 4 shows an alternative embodiment of a hinge structure for the freezer compartment door of the refrigerator.
• the two-temperature refrigerator 10 shown in a perspective front view in FIG. 1 comprises a heat-insulating body 12, on which an outer door 11 is hinged about a vertical axis.
• the interior of the body 12 is through a thermally insulating horizontal partition 14 divided into a normal cooling compartment 13 and a freezer compartment 15.
• the body 12 is constructed from an outer housing and an inner container deep-drawn from flat plastic material, which delimit an intermediate space filled with insulating foam material.
• a flap 16 is pivoted about a horizontal axis at the level of the intermediate wall 14.
• the flap 16 is shown in the figure in the open, horizontal position; in the closed position it closes the front of the opening of the freezer compartment 15 essentially airtight.
• FIG. 2 shows an exploded perspective view of a small piece of the inner container 17 of the body 12, a bearing pin 18 and part of the flap 16, seen from its inside facing the freezer compartment 15.
• the bearing pin 18 is a substantially cylindrical, cup-shaped hollow body with a closed end facing the flap 16 and an open end, which is provided to engage positively and non-positively in a recess 19 deep-drawn on the inner container 17.
• a circumferential rim 20 of the bearing pin 18 lies against the inner container 17 in the assembled state of the bearing pin and thus defines the depth of penetration of the pin into the recess 19.
• the side flank 21 of the flap 16 facing the bearing pin 18 has on its outer edge facing the outer door 11 a web 22 which also extends along the lower edge of the flank 21 and has an S-shaped curve there.
• This course delimits a circular depression 24 and a groove 23, which runs obliquely downward from the depression 24 and opens onto the lower edge of the flank 21, which is shown enlarged in FIG. 3.
• the diameter of the head section 24 is slightly larger than the width of the groove 23.
• the diameter of the head section is adapted to that of the bearing journal 18 such that the head section 24 can be freely rotated around the bearing journal 18, but the bearing journal 18 is too wide to without escaping elastic deformation through the groove 23.
• a blind hole 25 is formed on the opposite side flanks 21 of the flap 16 to receive an end portion of a tensioning strap (not shown), the other end portion of which is attached to the inner wall of the freezer compartment 15, and whose length is dimensioned such that it is taut in the open, horizontal position of the flap 16.
• FIG. 4 shows an exploded view of a second embodiment of a joint arrangement according to the present invention.
• a bearing pin 28 is provided so that it can be inserted into a recess 19 in the inner container 17.
• the bearing journal 28 differs from the bearing journal 18 of FIG. 2 in that the former has a recess 29 on its tip facing the flap 16, and in that the S-shaped region of the web 22 is characterized by a short journal 30 with an elongated, non-circular one Base area is replaced.
• a long dimension of the base of the pin 30 corresponds to the inner diameter of the recess 29, a short dimension corresponds to the width of an edge opening or notch 31 which is formed in the wall of the bearing pin 28 surrounding the recess 29.
• the longer length of the pin 30 lies in front of the edge opening 31 and therefore cannot escape from the recess 29.
• the short dimension of the pin 30 finally comes to lie in front of the edge opening 31, so that - possibly with a slight elastic deformation of the flank 21 of the flap 16, the bearing pin 18 or the inner container 17 in the vicinity of the recess 19 -
• the flap 16 can be pulled out of its anchoring or assembled.
• the elastic deformation can be a widening of the edge opening 31 if it is slightly narrower than the short dimension of the bearing pin 28 or it can is a deformation of the inner container 17 and / or the flank 21 transverse to the direction of the pivot axis defined by the bearing pin 28 and the pin 30.
