Definitions
- the present invention relates to a housing for a refrigerator with an outer housing box enclosing an inner space, and at least one intermediate floor, which is mounted in the inner space to divide it into subspaces.
- Typical refrigerators of this type are combination appliances, in which one compartment acts as a freezer compartment and a second as a standard refrigerator compartment.
- the shelves Since different temperatures must be maintained in the various compartments, the shelves must be tightly connected to the inner wall of the casing box and thermally insulated in a manner similar to the outer casing box which co-surrounds the compartments.
- such shelves are constructed as a hollow body, which are attached with their lateral edges close to the inner walls of the housing box and which are then foamed to achieve the necessary insulation capacity.
- This technique is similar to that with which the outer casing box is traditionally made: this is made up of outer and inner walls defining a cavity between them, which is foamed for thermal insulation.
- a refrigerator with two compartments of different refrigeration or freezing temperature, between which an isolated partition plate is arranged.
- the insulated partition plate is a one-piece molding made of a structural foam.
- Object of the present invention is to provide a housing for a refrigerator with a subdivided by an intermediate floor interior, in which the cost of the production of the inner bottom are reduced and its attachment is simplified.
- Another object is to specify a recycling-friendly housing.
- the invention provides that first an insulating body or core is produced from a foam material whose strength is sufficient to fix it directly to the inner wall of the housing.
- a dimensionally accurate production of a hollow body is superfluous; a dense covering of the core, which is desirable for protection of the foam material from contamination and from the ingress of moisture, may be constructed of one or more easily manufactured plates.
- the intermediate floor made of foam material can be easily mounted by sliding the core on at least one groove or a projection which is formed on the inner wall of the housing box.
- a complementary to a groove of the inner wall projection or to a projection of the inner wall complementary groove is formed on a lateral edge of the core.
- nubs are provided according to the invention on the lateral flanks of the core, which are deformed during insertion of the core into the interior and thus ensure a tight connection of the core to the inner wall.
- a sealing band can be arranged on the lateral flanks of the core.
- the already mentioned plates of the tight cover are conveniently held on the core by a plug or clamp connection.
- a connection is easily detachable during disassembly of the refrigerator and favors a sorted recovery of the materials used.
- it allows easy replacement of individual plates in case of damage, in contrast to the conventional art, where in case of damage to the hollow body this must be completely replaced together with its foaming.
- At a front of the core is preferably formed at least one groove for receiving heaters, which, when each of the subspaces is assigned a separate door, prevents condensation of humidity at the front of the core.
- a fan is provided in the subspace located below the intermediate floor, in particular for circulating cold air in the subspace, preferably at least one rib is formed on the underside of the intermediate floor, which surrounds a surface of the underside below which the fan is arranged.
- a rib if moisture on the underside of the false floor precipitates outside of this surface, prevents condensation droplets from migrating along the bottom to over the fan and dripping onto it.
- the area surrounded by the rib surface of the underside may be concave, so that condensate forming on the surface runs in the direction of the rib and drips on this.
- the core is preferably made of EPS (polystyrene foam).
- Fig. 1 shows in a highly schematic representation of a section through a refrigerator housing, in which the present invention is applicable.
- the housing comprises an outer housing box, which is composed of an inner container 1 and outer walls 2, and in which a gap 3 between inner container 1 and outer walls 2 is filled with insulating foam.
- An intermediate floor 4 divides the interior of the housing box into an upper subspace 5, for example a freezer compartment, and a lower subspace 6, for example a normal refrigeration compartment.
- Each of these subspaces 5, 6 is associated with a door 7 and 8, which adjoin one another at a gap 9 at the level of the intermediate bottom 4.
- the intermediate bottom 4 has a substantially L-shaped cross-section with a extending from the doors 7, 8 to the rear wall of the inner container 1 horizontal main portion 10 and an angled at the front edge of the main portion 10 down portion 11.
- This form of the false bottom 4 guaranteed on the one hand in the amount of the gap 9 a sufficiently thick insulating layer against penetrating into the gap from the outside heat;
- its thickness may be limited to a small value required for effective thermal insulation between the subspaces 5, 6 or sufficient mechanical strength of the intermediate bottom 4 so as not to reduce the available storage volume in the inner container 1 to compromise on the necessary level.
- Fig. 2 shows in an exploded perspective view of the structure of the intermediate bottom 4.
- This comprises a one-piece core 12 made of expanded polystyrene (EPS), which substantially fills the intermediate bottom 4.
- EPS expanded polystyrene
- Two horizontal grooves 13 are formed on the observer facing the front side 14 of the core 12; they are intended to receive a hot gas pipe (not shown) through which hot refrigerant is passed after passing through the compressor of a chiller and before passing through its heat exchanger to keep the front 14 warm so as to prevent condensation in the gap 9 is avoided.
- the horizontal grooves 13 are connected in the left edge region of the front side 14 by a vertical groove and go on the right edge portion in along the right side edge 15 extending grooves, so that the hot gas pipe is continuously laid through these grooves.
- a sealing tape 30 made of a closed-cell foam material such as ZPE is provided to (not shown) following the attachment of the hot gas line in the grooves or in specially provided for the sealing strip grooves on the side edges 15, front 14 and rear side of the core 12 to be and thus to ensure a tight connection of the false bottom 4 to the inner container 1.
- a sealing tape 30 is shown, but such sealing tapes can also be placed in pairs, in each case in the vicinity of the top and bottom of the core 12, respectively.
- both side edges 15 of the core 12 each have a guide groove 16 in the horizontal direction. It is provided to accommodate a formed on the inner container 1, complementary rib, so that the intermediate bottom 4 can be mounted by simply pushing the core 12 on these ribs.
- a horizontal rib could also be provided on a side flank of the core, which engages in a complementarily shaped groove of a side wall of the inner container 1.
- the top 17 of the core 12 is defined by an upper cover plate 18, e.g. Made of solid polystyrene, protected against damage and contamination.
- the cover plate 18 engages with its bent down front edge 19 in the upper of the two grooves 13 a; an analogous groove engagement with a groove on one of the side flanks 15 of the core or the rear side thereof may further be provided to clamp the upper cover plate 18 to the core 12.
- the underside of the upper cover plate could also be provided with thorns, possibly reinforced with barbs, which can be driven into the latter for mounting the cover plate on the core 12.
- a lower cover plate 20 which covers the underside of the core 12 is equipped at its front edge 21 in an analogous manner as the cover plate 18 with a retaining lug for engaging in the lower of the grooves 13. Also, it can be clamped by engagement of another retaining lug in a lateral or rearward groove of the core in the same manner as the upper cover plate 18 without adhesion to the core 12; also a fortification with the help of thorns comes into question.
- Fig. 2 also shows a downwardly directed rib 25 on the lower cover plate 20, which extends approximately C-shaped around a surface 26 of the lower cover plate adjacent to the rear wall of the inner container in the assembled state of the intermediate bottom.
- this surface 26 is provided to accommodate below her in the lower part of space 6, an electric blower 27.
- the rib 25 prevents moisture drops, which could form, for example, by condensation on the lower cover plate 20 outside of the surface 25 enclosed by the rib 25, reach the blower 27.
- a corresponding protection of the blower 27 in front of itself on the surface 26 forming condensate can be achieved when the surface 26 is down to the rib 25 down.
- a rib 28 is formed, which engages supportingly in the guide groove 16. In this way, a high load capacity of the false floor 4 is achieved without requiring excessive wall thicknesses of the cover plates 18, 20 or the core 12 are required.
- an additional rib 29 may be formed on the inner container 1 in the region of the lower partial space 6, on which the lower cover plate 20 rests.
