Definitions
- the present invention relates to a housing for a refrigerator, especially for a kuM-freezer combination device.
- the housings of refrigeration devices are conventionally constructed from an inner container, usually in the form of a one-piece plastic sheet deep-drawn shell, and an outer housing wall, which is usually composed of sheet metal plates, and which together delimit an intermediate space with a thermally insulating Foam material is filled.
- an inner container usually in the form of a one-piece plastic sheet deep-drawn shell
- an outer housing wall which is usually composed of sheet metal plates, and which together delimit an intermediate space with a thermally insulating Foam material is filled.
- Such a low outside temperature means that only very short run times of the refrigerant circuit are required to keep said warmest zone cool, which can be insufficient to simultaneously keep a colder zone of the device at its desired temperature.
- the heating element is used to artificially heat the warmest zone, so as to provoke runtimes of the refrigerant circuit which are sufficient to keep the colder zone at the desired temperature.
- the heating element used for this usually has the form of a foil heater, with a heating wire embedded between flexible foils, and is glued to an outer surface of the inner container, so that it is surrounded on the outside by the foam material in the fully assembled refrigeration device.
- the problem may arise that if the adhesive of the heating element is incomplete, local detachments of the heating element can occur, for example by penetration of the material forming the foam into pockets between the film and the inner container and foaming of the material in the pocket, or by pulling on the electrical supply lines of the heating element by expanding foam in the vicinity. If such detachments are present, the heat generated by the heating element cannot be released into the interior of the refrigerator in the desired manner, and it can local overheating, which damages the insulation foam and impairs its insulation effect.
- the object of the present invention is to provide a housing for a refrigerator with a film heater, in which a detachment of the film heater from the inner container during foaming is effectively prevented or at least limited to a non-critical level for the function of the device.
- a housing with the features of claim 1.
- the penetration of foam-forming material between the film heater and the inner container is prevented or at least at least if the film heater is incompletely bonded to the inner container to the extent that no detachments can occur over a large area and any material that may have penetrated between the inner container and the film heater escapes again largely between the inner container and the film when foamed under the counterpressure of the support plate, instead of tearing the latter off the inner container.
- the holding plate is provided with local openings which leave parts of the film heater visible in the assembled state of the holding plate, so that it can be ensured that the film heating has not been detached or moved by the attachment of the holding plate.
- the openings can be, in particular, spaces between wings that protrude transversely from a support tab of the holding plate.
- this support lip crosses the film heater in its longitudinal direction, and the wings extend in the transverse direction to the edge of the film heater in order to effectively protect it over its entire surface from detachment.
- two U-shaped claws are preferably formed on the support rib, which grip around the insulation-side sections of the support elements.
- their isolation-side section preferably has a shaft from which wings project, behind which the Can snap the claws of the holding plate.
- the claws can each be cranked onto the cavity, the offset being subjected to an elastic bending load when it is locked behind the wings, which holds the holding plate pressed against the film heating .
- a spring tongue can be used for the same purpose, which is molded onto a claw on its side facing away from the carrier rib and is supported on the inner container.
- FIG. 1 is a perspective view of the inner container of a refrigeration device with a film heater held thereon by a holding plate;
- FIG. 2 shows a detailed view of the inner container and the film heater attached to it, without the holding plate;
- Fig. 3 is a perspective view of the holding plate
- FIG. 4 shows a section through the holding plate along the line IV-IV from FIG. 3;
- FIG. 5 shows a detailed view of the inner container with the film heater and the holding plate.
- the inner container 1 shown in Fig. 1 for a refrigerator is formed by deep drawing from flat plastic material. It delimits two storage zones. A smaller zone in the upper area of the inner container 1 is provided in order to form a freezer compartment 2, the larger zones underneath form a normal cooling compartment 3. At the level of the normal cooling compartment 3, a plurality of openings are cut in the side walls of the inner container, in which suspension elements 4 for shelves to be mounted inside the normal cooling compartment 3, telescopic pull-outs or the like are arranged.
- the suspension elements 4 are each composed of two parts, an inner part 5, which is inserted from the inside of the inner container 1 into the corresponding opening and is held therein by latching or bayonet locking, and an outside of the section of the inner container 1 penetrating through the wall Inner part 5 turned outer part 6.
- the outer part 6 is approximately cup-shaped, with a flexible brim 7 projecting from the edge of the cup facing the inner container 1, which is pressed against one another by the locking of the inner and outer parts 5, 6 against one another in a foam-tight manner against the surface of the inner container 1 is held, and wings 8 projecting outward from the cup.
- Fig. 2 shows the lower region of the inner container 1 with the foil heater 9 without the holding plate 10.
- a heating wire 11 is enclosed between two plastic films 12, one of which is glued flat to the inner container 1.
- Electrical supply lines 13 for supplying energy to the heating wire 11 are guided on the rear of a frame 14 of the inner container to a control circuit (not shown).
- the holding plate 10 held by the two suspension elements 4 adjacent to the foil heater 9 pressed against the foil heater 9 is shown in FIG. 3 in an enlarged perspective view and in FIG. 4 in section along the line IV-IV from FIG. 3.
- the holding plate 10 has a rigid support rib 15, which ends at its ends in two U-shaped claws 16 which are open transversely to the longitudinal direction of the support rib 15.
- the support rib 15 has a cross section in its area between the claws 16 with a V-like curved central area 17 and flat side strips 18 adjoining it laterally.
- the side strips 18 are extended at both intervals at regular intervals
- On the sides of the support rib 15 projecting wings 19, 20 are formed.
- the wings 19, 20 have a flat underside facing the film heater 9 and an upper side stiffened by narrow webs 21.
- the wings 19 extending to the open side of the claws 16 are slightly angled at their free ends 22, so that the tips of these wings 19 cannot get caught on the edges of the foil heater 9 when the holding plate 10 is pressed against the outside of the inner container 1 and is shifted thereon in order to cast them onto the suspension elements 4 adjacent to the film heater 9.
- the legs of the claws 16 are pushed through a gap between the wall of the inner container 1 and the edge facing this wall of a wing 8 protruding radially from the outer part 6 of a suspension element 4 until they slide elastically against them during the pushing through Leg pressed tongue 24 has completely passed the gap and moves away from the leg again and the wing 8, as can be seen in particular in FIG. 5, abuts the stop 23. In this position, the wing 8 is caught between the tongue 24 and the stop 23, and the holding plate is on the Suspension elements locked.
- the support rib 15 has a cranked section 26 at the transition to the right claw 16, and is on a side of the right claw 16 facing away from the support rib a flexible tongue 25 is formed, which touches the inner container 1 with its free end. Tongue 25 and cranked section 26 are under a bending load, so that the right claw resiliently presses against the wings 8 of the right suspension element and the holding plate 10 resiliently against the foal heating 9.
- the feed lines 13 of the film heater 9 can be passed to the time between the sticking of the spring tongue to the inner container 1 and the foaming of the gap between the inner container 1 and (not ) outer wall plates of the refrigerator housing to provide strain relief for the feed lines 13 of the film heater 9.
