Description

Domestic refrigerator with a specific boundary wall of a machine room

The invention relates to a household refrigerator with a housing in which an inner container which defines an interior for receiving food, is arranged. In addition, the household refrigerating appliance includes a machine room separated from the interior, in which components of a refrigeration cycle of the household refrigerating appliance are arranged.

A household refrigerator, such as a refrigerator or a freezer or a combined refrigerator-freezer, comprises a refrigeration cycle for refrigeration in the food receiving space in the inner container. This usually includes a compressor, an evaporator and a condenser. This allows the generation of cold temperatures in the interior. Usually, it is provided that the compressor is arranged in the machine room. In addition, it is usually also provided that electronic components and / or collecting containers for accumulating defrost water are arranged therein. The engine room is usually limited by walls. For electrical power supply and / or for the fluidic conduction of the refrigerant lines are led to the components in the engine room. In known embodiments, a type of chamber is provided here with slotted walls, wherein the lines are placed in these slots of the chamber walls. Several foam parts are used for foam-side sealing, which envelop the lines. Since usually between the inner container and the housing, which surrounds the inner container, a gap is formed in the thermally insulating material, in particular a foam material, is introduced, thus disadvantages are given in this embodiment. Because occurs in the manufacture and thus the introduction of the foam in the space such a in the chamber, a chamber occluding part is pressed within the manufacturing and assembly tolerances. This also has a disadvantageous effect on the tightness. It is an object of the present invention to provide a household refrigerator, in which a reliably tight routing is achieved in the engine room.

This object is achieved by a household refrigerator, which has the features of claim 1.

A domestic refrigeration appliance according to the invention comprises a housing which surrounds an inner container which delimits an interior for receiving food. In addition, the household refrigerating appliance comprises a machine room separated from the interior, in which at least some components of a refrigeration circuit of the household refrigerating appliance are arranged. An essential idea of the invention is to be seen in that the machine room has a boundary wall, on which a line feedthrough box for passing at least one line from outside the machine room into the machine room is arranged. The box has a pot and a lid for closing the pot, wherein the lid is integrally connected to the pot. By this configuration, a wiring is achieved in the engine room, in which the box can be closed reliably holding and sealed. Even if thermally insulating material, in particular foam material, is introduced during manufacture between the housing and the inner container, the box remains closed. The problems mentioned in the prior art do not occur here.

It is preferably provided that the connection between the lid and the pot is a film hinge. This embodiment allows a very smooth movement of the lid. It is also permanently stable in function and relatively easy to manufacture. Especially in the case of a one-piece design of the lid with the holding pot, therefore, such a film hinge is particularly advantageous.

It is preferably provided that the box is formed at least with its pot on a side facing away from the engine room outside of the boundary wall and facing away from the outside of the engine room to the outside. This box is thus a raised on the outside of the boundary wall outwardly component. This is advantageous in that the engine room characterized in its useful volume is not limited. Since a corresponding intermediate space is then formed between the machine room and the housing anyway, in which then the thermally insulating material, in particular the foam material, is introduced, such an additional element in the form of this receiving pot does not interfere with this intermediate space. In addition, especially in such an arrangement of the box with the pot, the invention is particularly advantageous because thus at least this pot is circumferentially exposed to the foam material. Especially the one-piece design of the pot with the lid then allows in such a configuration particularly advantageous to prevent the box could be pressed by the foam material and the foam material could reach undesirable locations.

It is preferably provided that the cover is arranged partially facing the engine room in the closed state of the box. Also, this then some protection against the foam material is achieved because the foam material then covers the pot or surrounds and partially the lid.

It is preferably provided that the box is integrally formed with the boundary wall. As a result, a position-safe arrangement of the box is achieved and also allows the integration of the box in the boundary wall, a component reduction. In particular, however, this also manufacturing advantages and installation advantages are achieved because no separate items must be made, which would then be associated with additional effort.

Preferably, the boundary wall with the box made of plastic, in particular as an injection molded part.

Preferably, it is provided that the lid has an at least partially circumferential rib on a side facing the pot in the closed state of the box, which rests against inner sides of the walls of the pot in the closed state of the box. By such a configuration, a special tightness of the closed box is achieved. Thus, not only a lid is constructed, which rests on the pot, but it is almost achieved in the closing direction of the lid meshing between the lid and the pot, so that in particular, this circumferential rib also engages in the interior of the volume enclosed by the pot and extends into it. Also, the positional fixation between the lid and the pot is improved by such an embodiment. It is preferably provided that the lid has a latching element on a inside facing the pot in the closed state of the box, which engages in a closed position of the box in a locking receptacle on an inner side of a first wall of the receptacle pot. By this configuration, the closed state of the box is kept mechanically improved. In addition, by virtue of this specific configuration and arrangement of the latching element, in the closed state of the box, the connecting element, which is preferably designed as a film hinge, is relieved of its load between the cover and the receiving pot. As a result, it remains permanently stable in function. Preferably, it is provided in the context that this locking element is arranged on the inside of the lid immediately adjacent to the film hinge and also the locking receptacle is arranged on the inside of the first wall of the receiving pot adjacent to the film hinge. The advantages mentioned above are thereby further favored.

It is preferably provided that the cover has a tab-like latching receptacle on one edge side, into which, in the closed state of the box, a latching element engages on an outer side of a second wall of the receptacle pot. Preferably, this edge side of the lid is one of the edge sides, to which the connecting element, in particular the film hinge, for connection to the pot, not arranged. Preferably, this edge side with the tab-like locking receptacle of those edge side of the lid opposite to which this connecting element is arranged. By means of this specific embodiment, a mechanically fixed coupling of the lid to the pot is then achieved on the opposite side of the connecting element in the closed state, so that the closed state is held at several points and thus several edge sides.

It is preferably provided that in the box at least one sealing element is arranged with a line feedthrough as a filling body. By this configuration, the at least one cable through the box is not inside the box exposed and loose running, but at least partially surrounded by this sealing element and thus also supported part position. In addition, an improved protection against a foam material is achieved by this sealing element again. The sealing element is thus also a support body for the performed lines, and the sealing element surrounds the line circumferentially completely. This means that the sealing element has a passage in the form of a hole or a bore, through which then extends the at least one line.

Preferably, the sealing element is arranged in an inner space of the box at least in two spatial directions accurately in it. At least in these two spatial directions thus fixing a position to the lid and the pot is achieved in the closed state of the box. Preferably, it is provided here that the sealing element is arranged in three spatial directions accurately in the interior of the box. As a result, the volume provided in the box is quasi filled by the sealing element and only the at least one passage for the line is present.

It is preferably provided that the cover has a groove for receiving a further boundary wall of the machine room on an outer side facing away from an interior of the box. This allows a very simple connection between two separate boundary walls, and the lid then serves in the context as a multifunctional part. Not least is achieved by such a configuration then also that the further boundary wall hineinerstreckt into this groove in the lid and extends beyond the dimensions of the lid, so that by the support of this further boundary wall then also on other components further pressing and against an opening direction effecting holding this further boundary wall is achieved on the lid. As a result, an undesirable opening of the lid is even better prevented.

It is preferably provided that the groove in the lid is oriented vertically in the closed state of the lid. The groove on the outside of the lid is preferably designed as a slit-like configuration protruding from the outside, into which the further boundary wall then extends. Preferably, it is provided that these deck-internal groove opens in the closed state of the lid at both ends in the groove external to the lid, which are designed to receive the further boundary wall. It is thus virtually created a continuous and directly merging Gesamtnut into which the other boundary wall on the dimensions of the lid can extend into time and thus in this regard position part outside the lid is held reliably.

It is preferably provided that the further boundary wall is a cardboard wall, which is thus designed from the material cardboard. This can thus be provided relatively thin and yet fully functional and cost-minimal.

It is preferably provided that the boundary wall is formed with the box made of plastic. The boundary wall with the box is preferably a vertical side wall that defines the engine room. In particular, it is provided that a line feedthrough channel of the box is oriented at an angle between 30 ° and 70 °, in particular between 30 ° and 60 ° to a vertical. Such an oblique introduction causes advantages in terms of unwanted and strong kinks of the line. In particular, it is provided that by the preferred inclination of the box at an angle between 30 ° and 70 °, preferably between 30 ° and 60 °, relative to a vertical and the lid partially within the engine room and partially outside the engine room in a space between the engine room and the inner container or the housing is arranged. By this arrangement, in which then virtually the other boundary wall causes this division of the lid on the one hand in a partial area extending in the engine room, on the other hand in a partial area extending outside the engine room, the reliable closed position is held and then Also located outside of the engine room section of the lid by the then directly acting foam material additionally pressed.

Further features of the invention will become apparent from the claims, the figures and the description of the figures. The features mentioned above in the description and Combinations of features, as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figures, can be used not only in the respectively specified combination but also in other combinations or alone, without departing from the scope of the invention. Thus, embodiments of the invention are to be regarded as encompassed and disclosed, which are not explicitly shown and explained in the figures, however, emerge and can be produced by separated combinations of features from the embodiments explained.

Embodiments of the invention are explained in more detail below with reference to schematic drawings. 1 shows a perspective front view of an exemplary embodiment of a household refrigerating appliance according to the invention; Fig. 2 is a rear perspective view of the household refrigerator according to FIG.

10 shows two exemplary perspective views of sealing elements for use in the box.

In the figures, identical or functionally identical elements are provided with the same reference numerals. In Fig. 1, a household refrigeration device 1 is shown in a perspective front view, which has a designed as an outer housing 2 housing. The housing 2 surrounds an inner container, which defines two different separate inner spaces 3 and 4, wherein the inner spaces 3, 4 are designed for receiving food. By way of example, the lower interior 4 is closed by a door 5. The upper interior 3 is shown for inspection in this without such a door, which is actually present in the household refrigerator 1, however.

The household refrigerator 1 may be a refrigerator or a freezer or a refrigerated combined freezer. It comprises at least one refrigeration cycle, by means of which a corresponding cold temperature is generated in the interior spaces 3 and 4. The refrigeration cycle comprises a refrigerant compressor 6 or compressor shown in FIG. 2, which shows a perspective view of the domestic refrigerator 1 from behind. The refrigeration cycle also includes, in particular, a condenser and an evaporator. The refrigerant circulates in the circuit.

As can be seen in Fig. 2, the refrigerant compressor 6 is disposed in a rear lower portion of the household refrigerator 1. This area represents a machine room 12. It is separated from the interiors 3 and 4. The engine room 12 is designed to receive components of the refrigeration cycle.

The refrigerant compressor 6 generates in operation a waste heat, which is used, defrost water formed in the household refrigerator 1, which is collected to evaporate. For this purpose, the household refrigerating appliance 1 comprises a device 7, which is designed to receive defrosting water and which is likewise arranged in the machine room 12 in at least subcomponents. For this purpose, a collecting tray 8 of the device 7, which is designed to collect defrosting water, is arranged in the machine room 12. It is arranged virtually above the refrigerant compressor 6, so that the thermal coupling is given to the evaporation of the collected defrost water.

The device 7 also includes a collecting bowl 9 for the defrosting water, which is connected by a connecting line 10 with the drip tray 8.

The device 7 further comprises a carrier shell 1 1, which is provided for receiving the collecting tray 9, and which is also arranged in the machine room 12.

The engine room 12 is bounded by boundary walls. For this purpose, a first lateral boundary wall 13 is provided in the enlarged partial view in Fig. 3, which represents a vertical wall. To the inner container further boundary walls 14 and 15 are provided, wherein in addition a not shown in Fig. 3 and the first boundary wall 13 opposite lateral boundary wall is provided. These lateral boundary walls, of which only the boundary wall 13 is shown in FIG. 3, are one-piece plastic parts, which are produced in particular as injection-molded parts. In contrast, the other boundary walls 14 and 15 cardboard walls.

In addition, it should be mentioned that in a gap 16 between the engine room 12 and the inner container which defines the interiors 3 and 4, and moreover also in the intermediate space between this inner container and the housing 2, a thermally insulating material, in particular a foam, is introduced.

As can be seen in Fig. 3, one or more lines for the electrical power supply of the arranged in the engine room 12 components and / or To provide lines for guiding the refrigerant, which are guided in this engine room 12. For this purpose, it is provided in the exemplary embodiment that at this lateral first boundary wall 13, a line feedthrough box 17 is formed integrally and thus in one piece. Lines 18a, 18b and 18c are shown by way of example. The box 17 has a cuboid shape and is also inclined relative to a vertical, which thus extends in the y-direction, at an angle α between 30 ° and 60 °. This refers to a defined longitudinal axis A of the box 17th

In addition, it is preferably provided that the box 17 is integrally formed on an outer side 13a, which thus faces away from the machine room 12 and faces the intermediate space to the inner container and / or the housing 2. The box 17 thus extends raised against the outer side 13 a in this space and it is thus outside of the engine room 12 and thus arranged foam side. This means that it is surrounded by the foam in the gap and thus substantially extends with its dimensions within this gap.

In Fig. 4 is a perspective sectional view of the view in Fig. 3 is shown. The box 17 comprises a pot 19 and a lid 20 which is integrally connected to the pot 19.

In Fig. 5, the illustration in Fig. 4 is shown in a different perspective. The orientation about the arrangement of the box 17 relative to the walls 13, 14 and 15 can be seen. In the closed state of the box 17, as shown in Fig. 3 to 5, the lid 20 of the boundary wall 13 faces and the pot 19 facing away in this regard.

FIG. 6 shows an enlarged view of the partial section of FIGS. 3 to 5, in which the box 17 is arranged.

The lid 20 is connected in the context of film hinges 21 and 22 with the pot 19 and pivotable relative thereto. In addition, it is too recognize that on an outer side 20a of the lid 20, which is thus facing away from the pot 19, a raised groove 23 is formed. This groove 23, which is designed as a relation to the outer side 20a raised projecting slot, the wall 15 is inserted and received. As can be seen from Fig. 6, the groove 23 is vertically oriented in the closed state of the box 17 and thus extending in the y direction. Due to the orientation of the box 17 and thus also of the lid 20, this groove 23 extends quasi across the lid 20 and thus in particular between two opposite corners of this cover 20th

By virtue of this orientation and arrangement of the groove 23 and the wall 15 then inserted therein, which likewise delimits the machine room 12, the outside 20a is subdivided into two almost triangular surface regions or partial regions 20b and 20c. It can be seen that in the closed state of the box 17, the portion 20b is located in the machine room 12 and the portion 20c extends outside thereof and thus in the space which is filled with foam, is arranged. In addition, it can be seen that opposite ends 23a and 23b of the groove 23 open into adjacently arranged and further open-out grooves 24 and 25, so that cover-overlapping an overall groove is formed into which the further boundary wall 15 is inserted. In Fig. 7, the boundary wall 13 is shown in a perspective view, in which case the integrated box 17 is shown in the open state. As can be seen in this view and, moreover, in the enlarged illustration in FIG. 8, on an inner side 20d which, in the closed state of the box 17, faces the pot 19 and thus also the inner volume 26 of the box 17, at least in regions circumferential rib 27 integrally formed. This engages in the closed state of the box 17 in the pot 19, so that the lid 20 is not only seated on the pot 19, but is arranged interlocking. The rib 27 is preferably seated on a pedestal 35, which is formed on the inside of the peripheral boundary walls of the pot 19, on.

In addition, it is provided that the cover 20 has a latching element 28 at an inner side 20 d facing the receiving pot 19 in the closed state of the box 17. The locking element 28 is on the edge side, on which the connection of the Cover 20 is given to the film hinges 21 and 22, arranged. The latching element 28 engages in the closed state of the box 17 in a latching receptacle 29, which is formed on an inner side of a circumferential first wall of the receiving pot 19. Also, this locking receptacle 29 is disposed adjacent to the film hinges 21 and 22 and thus formed in particular on that first wall of the receiving pot, to which the film hinges 21 and 22 open.

By this film hinge close locking coupling between the lid and the pot 19, a relief of the film hinges 21 and 22 is achieved in the closed state of the box 17.

In addition, it is provided that on one edge side 30 of the lid 20, which is opposite to that edge side which opens to the film hinges 21 and 22, a tab-like locking receptacle 31 is formed. This is designed so that in the closed state of the box 17, a latching element 32, which is formed on an outer side of a further lateral wall of the pot 19, engages. This locking element 32 is formed on that peripheral wall or lateral wall of the receiving pot 19, which is opposite to the side wall to which the film hinges 21 and 22 open. It is thus achieved for latching coupling between the locking element 28 and the locking receptacle 29 beyond an additional on opposite walls or edge sides detent coupling, so that the closed state of the box 17 is held particularly advantageous.

9, the illustration in Fig. 8 is shown, but with a view to the outer side 13 a of the boundary wall 13, so that is not looked at from the engine room 12 to the outside, but is looked from the outside in the direction of the engine room 12.

In Fig. 10, two embodiments of perspective views of a sealing element 33 are shown, as they can be arranged in the box 17. The sealing elements 33 are also cuboidal parts, which are preferably in all three spatial directions accurately in the box 17 can be attached and thus completely fill the inner volume 26 to a passage 34. The bushings 34 are axial and formed depending on the respective diameter for receiving different lines. The sealing element 33 is thus also a packing.
