Description

Domestic refrigerating appliance with a door opening unit introduced from below into a floor unit and method for assembling a household refrigerating appliance

The invention relates to a household refrigerator with a housing in which a receiving space for food is formed. In addition, the household refrigerator also includes a door which is designed to close the receiving space and is arranged accordingly. The door is movably disposed on the housing, the housing having a bottom unit. Moreover, the invention also relates to a method for mounting a door opening unit of the household refrigerating appliance.

Domestic refrigerators have a variety of components that usually have to be arranged compact in order to keep the volume of the household refrigerator as compact as possible. In this context, components of a refrigeration cycle are required, which are arranged at different positions in the household refrigerator and interact. In addition, however, other components of electronic nature are also provided, which are associated, for example, with an operating device and / or a display device. Since even with household refrigerators, the thermal insulation effect is essential, also appropriate thermal insulating material must be provided so that the receiving space can be controlled accordingly and also remains cool. This also results in further requirements to the effect that components and feeds of electrical and / or fluidic nature can not be laid arbitrarily, so as not to impair this thermal insulation effect and thus not undesirable circumferential and often penetrate the thermal insulation material.

It is an object of the present invention to provide a household refrigerating appliance and a method in which the attachment of a specific functional component is simple and can be easily brought to its final position with regard to the assembly process. This object is achieved by a household refrigerator and a method according to the independent claims.

An inventive household refrigerator comprises a housing in which a receiving space for food is formed. The household refrigerator further comprises at least one door for closing the receiving space. The door is arranged movably on the housing. The housing comprises a floor unit. This floor unit is designed as an outer part of the housing and thus at least partially closes off the household refrigerating appliance to the outside. This floor unit comprises a receiving shaft, in which a door opening unit, which is designed for at least opening support of the door, is arranged. This receiving shaft has a viewed in the height direction of the household refrigeration device downwardly open access opening, through which in particular this door opening unit can be inserted from below for mounting in the receiving space. Thus, according to the invention, a very specific functional module or a specific functional unit, namely this door opening unit, is installed, which thus makes possible a further advantageousness with regard to the functionality of the household refrigerating appliance. Namely, with this door opening unit, it becomes easier for a user to open the door since the required pulling forces are reduced. For through this door opening unit a certain additional pressing of the door is generated, which simplifies handling. Just when, due to thermodynamic conditions in the receiving space, the door has sucked a little harder in its closed end position, this door opening unit supports and facilitates the door opening procedure for a user. Just this specific door opening unit is then arranged by the invention also item part quite individually and then installed in their final position. Thereby, this opening support function is achieved particularly advantageous and in which this opening unit is arranged in the bottom unit, it is not disturbing in the way, even if the door is open and optionally an opening plunger is extended forward. An abutment of a user himself or with an object when filling the receiving space or when removing it from the receiving space on the opening plunger is avoided by this fully installed at the lower position position. As a result, an undesirable damage to the opening plunger can be avoided. Just this position of the door opening unit is then particularly advantageous by the invention with regard to the shoring. The accessibility from below allows the final installation of the door opening unit even if the thermally insulating material is already introduced in the appropriate places. It can thus be done from below even when the foaming process is completed. This also has significant advantages in terms of the subsequent steps in the manufacturing process, because the door opening unit with its door feed lines does not have to be fixed in position before the foaming process and be protected from escaping foam material. In particular, it is provided that the floor unit has a bottom plate in which the access opening is formed. As a result, an access opening is created, which extends in a plane in which also extends the bottom plate, so that viewed in the height direction of the household refrigerating appliance and the receiving shaft is designed as flat as possible. If the access opening would not only extend in one plane but also have a certain three-dimensional shape, the receiving shaft would also have to be made correspondingly more voluminous. In addition, this specific position of the access opening in this particular flat base plate is also advantageous for the insertion behavior of the door opening unit into the receiving shaft. Thus, no complex movement sequence has to be carried out in order to be able to thread the door opening unit over the access opening, but simple insertion with a simple pivoting movement is sufficient.

It is preferably provided that the receiving shaft has a hood-like cover, which is arranged on the ground unit as a separate component via the access opening. The receiving shaft is then bounded laterally and upwardly by the insides of the cover and the access opening is covered from above. The cover is formed so that it is open towards the front when viewed in the depth direction of the household refrigerating appliance, so that an opening plunger of the door opening unit can move out of the receiving shaft in this depth direction. This embodiment then protects the door opening unit in front of the inwardly following structure of the household refrigerating appliance, in particular a thermal insulation material, which is then introduced. By this cover is on the one hand the receiving shaft clearly limited, on the other hand, a direct contact of the thermal insulation material with the door opening unit can be improved prevented.

The cover is in particular in one piece, preferably made of plastic. In particular, it is provided that the cover has a stiffening structure, in particular integrated. As a result, precisely that region which forms the ceiling is stiffened, so that undesired bulging or pushing through in the direction of the volume space of the receiving shaft is avoided when the thermally insulating material is introduced. In particular, an insulating expansion foam can not then undesirably press down this cover blanket. This also avoids that the volume space of the receiving shaft would be reduced so that the door opening unit would then no longer find room, especially in the height direction. In particular, it is provided that the stiffening structure has line-shaped stiffeners, which are preferably formed in a grid structure, in particular in a matrix pattern. The mechanical stability of the cover is thereby increased particularly advantageous. Preferably, it is provided that the cover integrally has a groove-like and downwardly open cable channel for cable feed to the door opening unit. This makes it particularly easy to move an electrical cable or a cable in the form of a hose or other line for fluid supply to the door opening unit locally specifically and then also already protected to record. As a result, the assembly is simplified and achieved faster and accurate registration of these cables. By integrating this cable channel into the cover, the connecting and connecting of the cable to the door opening unit is thus also possible at any time in a targeted manner, so that no unnecessary additional installation effort with incorrect mountings occurs here as well. Electrical and / or fluidic contact or a corresponding connection between the cable and the door opening unit is therefore always reliable. It is preferably provided that the cover is attached non-destructively non-releasably attached to the ground unit, in particular glued or welded. For example, ultrasound welding can be mentioned here particularly advantageously, in particular if the bottom unit is also formed in this connection region with the cover made of plastic. This embodiment also makes it possible to realize a very tight connection, so that undesired passage of thermally insulating material, in particular insulating foam, is prevented at the component interface between the cover and the bottom unit.

In particular, it is provided that in a further advantageous embodiment, the cover is attached non-destructively releasably attached to the ground unit. It can also be provided in particular a screwing or latching.

It is preferably provided that viewed in the depth direction of the household refrigerating appliance in front of the receiving shaft and thus a front side cover strip is arranged, which covers a slot-shaped front opening of the cover and which has a respect to the dimensions of the front opening smaller passage for passing through an opening plunger of the door opening unit. By this cover strip, a corresponding position stop for the cover is also provided in the depth direction, so that it can also be arranged accurately positioned and then attached to the ground unit. In addition, by dimensioning the implementation of this cover also prevents the mounting of the door opening unit as this entire component over the slot-shaped front opening of the cover could undesirably slip out far forward, so that here by this cover the positionally accurate attachment of the door opening unit is supported.

Preferably, it is provided that the cover strip is integrated in the bottom unit and thus in particular also so that it is made in one piece. As a result, the number of components can be avoided and the permanently positionally accurate arrangement of the cover strip can be achieved in particular to the access opening. Additional installation effort to attach the cover strip is not required.

It is advantageously provided that, viewed in the depth direction, the household refrigerating appliance is arranged in front of the covering strip and thus at the end side a further end strip is that has a further passage for passing through an opening plunger of the door opening unit. This front strip is in particular an angled component, so that the stability is correspondingly high. As a result, a front-side stop can be formed by this front strip, which stabilizes the housing at this point. In particular, this front strip is formed of metal, so that the bottom unit at this front point at which then opens the receiving shaft and in particular is limited by the cover strip of the bottom unit, stabilized. An abutment of other components, for example, during assembly, or a Daranstoßen when installing the domestic refrigerator then protects the floor unit and in particular the cover and the door opening unit from unwanted mechanical damage, so that damaging the cover and / or the door opening unit is prevented , Furthermore, the particular L-shaped end strip is a support part for the ground unit. The end strip is then preferably connected to other supporting parts, so that a stable support structure is formed. Also in this front strip, the dimensioning is preferably provided for the further implementation that only the opening plunger can extend therethrough and this is provided with a correspondingly low clearance. As a result, no unnecessarily large dimensioned further implementation is provided, so that an entry of dust or liquids or the like is restricted, in particular the passage of these media up to the receiving shaft is avoided.

In particular, it is provided that the cover on its side facing away from the receiving shaft with thermal insulation material, in particular insulation foam, is covered. It is thus provided a direct contact of the insulating material with this cover, so that even in the region of the receiving shaft still a sufficient thermal insulation effect to the receiving space occurs.

It is preferably provided that the access opening to a separate cover to the bottom unit is closed downwards, wherein the lid is non-destructively releasably attached, in particular screwed. As a result, the accessibility is always given even after installation, for example, for maintenance or replacement of the door opening unit. This is therefore very quick and easy and beyond even without extensive dismantling of other functional components. All you have to do is remove this cover. The lid is beyond Also advantageous so that no contamination of the receiving shaft occurs via the access opening, and also the high functional resistance of the door opening unit remains.

It is preferably provided that the bottom unit is formed in one piece. Viewed in the depth direction of the household refrigerating appliance, the floor unit has, in addition to a front-side base plate, a rear-side covering hood which adjoins the rear and which is designed to define a machine room of the household refrigerating appliance. In the engine room in particular components of the refrigeration cycle of the household refrigerator are arranged. This embodiment thus makes possible a ground unit which shoots the housing completely downwards and accommodates different functional components of the household refrigerating appliance at different points or provides individual receiving shafts.

Preferably, it is provided that the door opening unit has a main housing, in which an opening plunger is movably arranged, wherein this front side of the main housing this opening plunger herauserstreckt or can extend out. The door opening unit comprises in addition to the main housing to a separate contact housing, which has at least one electrical connection and / or a pressure hose connection, and which is arranged on the back of the main body non-destructively releasably, in particular latched.

In particular, it is provided that the door opening unit has a position in which, in particular rectilinear sliding movement of the opening plunger in the depth direction of the household refrigeration appliance with the door closed, a corresponding contacting the door through the opening plunger and then take place force is applied to at least opening support the door. In particular, therefore, this door opening unit is arranged in the area of the floor unit so that it is covered by the door when the household refrigerator is viewed from the front while the door is closed. The door opening unit thus sits with the door closed behind the door and is covered by the flat dimensions of the door.

Furthermore, the invention also relates to a method for assembling a door for at least opening support of a household refrigerating appliance, in particular one Household refrigerating appliance according to the invention preferably according to one of the preceding embodiments, formed door opening unit, in which the door opening unit viewed in the height direction of the household refrigerating appliance from a bottom of an outer part of the housing of the household refrigerating appliance forming bottom unit of the household refrigerating appliance introduced by a downwardly open access opening in the bottom unit in a receiving shaft and is positioned there in its final position. Such a mounting scenario of a very specific functional unit of the household refrigerator allows particularly high flexibility in the production process of domestic refrigeration appliance and also allows in the finished state, the accessibility to the door opening unit at any time. It is also easily and quickly brought into the final position by this mounting scenario and can therefore also be assembled and disassembled accordingly. In addition, it is very space-saving and not distracting positioned for other units just by this design. Advantageously, the receiving shaft is covered at the top by a cover which is mounted prior to the introduction of the door opening unit. In particular, this cover is attached to the floor unit, to which the cover is a separate component and is provided accordingly. Preferably, gluing or ultrasonic welding is carried out here. However, it can also be provided a screwing or latching. This cover is provided as a trough-like component and thus represents a hood-like cover of this downwardly open access opening in the bottom unit. In the method according to the invention is then advantageously achieved that an introduction of a thermally insulating material in a space between the bottom unit and an inner container, the limited the receiving space with its walls, even then can be carried out when the door opening unit is still not mounted in principle in the receiving shaft. This also has significant advantages for the course of the entire manufacturing process of household refrigeration appliance, just for the introduction of the thermally insulating material on the one hand and the corresponding Verbau the door opening unit on the other. In particular, it is provided that the cover integrated has a cable channel, so that the introduction of the thermally insulating material prior to installation of the door opening unit does not affect a subsequent cable installation. The exact position and the exact Guideway for these cables is then already fixed by the cable channel and is no longer affected by the introduction of the thermally insulating material. Thus, even after the introduction of the thermal insulation material relocation of the leads, in the form of electrical cables or cables in the form of hoses or lines of fluids quickly, accurately and permanently always in the same place possible. It can then be provided that this area is closed foam-tight with a foam part.

In the subsequent subsequent assembly of the door opening unit, in particular after the introduction of the thermally insulating material, this is made possible very easily from below via this access opening. A comprehensive complex langwegiges moving the door opening unit far into the interior of the housing is no longer necessary. Due to the large-sized access opening and then directly provided in this respect receiving shaft mounting the door opening unit is also very easy and fast. Through the cable channel no cable is exposed exposed or visible even when installed, especially when the access opening is closed from below even by a separate lid.

In an advantageous embodiment, it can be provided that, after fastening the cover on the floor unit and before introducing the thermally insulating material, a support element similar to the door opening unit is introduced into the receiving shaft, through which the volume of the receiving space is filled, so that during insertion the thermally insulating material no undesirable deformation of the cover occurs and thus no undesirable reduction of the volume of the receiving shaft occurs. Even with expanding insulation foam and thus corresponding mechanical force on the cover this remains dimensionally stable and after curing of the insulation foam can then be removed from this support element to then finally mount the door opening unit can.

In Fig. 1, a household refrigeration appliance 1 is shown in a simplified perspective view, which is designed for receiving food. The household refrigerating appliance 1 comprises a housing 2, in which at least one receiving space 3 for receiving food is formed. In particular, it is provided here that two separate receiving spaces are provided, which can be closed by a respective door. In particular, it is provided here that a receiving space 3 can be closed by a door 4 and a further receiving space 5 by a further door 6. The doors 4 and 6 are arranged in the width direction and thus in the x-direction side by side and positioned in the vertical direction and thus in the y-direction at the same height to each other. They can be actuated independently of one another and are each arranged pivotably on the housing 2 about a vertical axis.

The household refrigerating appliance 1 further comprises a bottom unit 7, which constitutes an outer part of the housing 2, and closes the housing 2 downwards and thus viewed downwards in the height direction. The floor unit 7 also covers a machine room 8 to the front and from above, wherein in the engine room 8 in particular components of a refrigeration cycle of the household refrigerating appliance 1 are arranged. In Fig. 2, another embodiment of a household refrigerator 1 is shown. In contrast to the representation according to FIG. 1, here the first receiving space 3 is likewise a coherent receiving space which extends over the entire width. Viewed in the height direction below the receiving space 3, a second receiving space 5 is formed, which is closed by a separate door 9. The receiving space 3, however, is closed by the doors 4 and 6.

Another embodiment of a household refrigerator 1 is shown in FIG. In this embodiment, in contrast to the embodiment according to FIG. 2, the upper contiguous receiving space 3 can be closed by a single door 4.

4, the household refrigerating appliance 1 according to FIG. 3 is shown in a partial representation, wherein the following explanations apply to this embodiment also for the embodiments according to FIGS. 1 and 2. As can be seen, the receiving space 5 is bounded by an inner container 10 or its walls. The bottom unit 7 is a separate, in particular one-piece unit made of plastic, which is arranged below the inner container 10. A gap 1 1 between the bottom unit 7 and the inner container 10 is filled with a thermally insulating material, in particular an insulating foam. The bottom unit 7 is formed with a receiving shaft, wherein in FIG. 4, a cover 12 of the receiving shaft can be seen, which mitbegrenzt the volume of the receiving shaft and covers from above. In this receiving shaft, a door opening unit can be inserted and positioned in the receiving shaft via a in the bottom unit 7 downwardly open and thus accessible from below access opening. The door opening unit has an opening plunger 13, which is displaceably mounted in the linear direction and thus in the depth direction (z-direction). The receiving shaft already mentioned has towards the front and thus to the door 9 a front opening, through which then this opening plunger 13 can move. As can be seen in Fig. 4, the door opening unit and thus also the opening plunger 13 is arranged so that in the closed state of the door 9, this also covers the door opening unit in the vertical plane and thus in the xy plane. To actuate the door opening unit moves the opening plunger 13 forward, and the case The opening force generated acts on the door 9, so that it is pressed from the closed state.

In Fig. 5, the illustration of FIG. 4 is shown from a different perspective. It can be seen that the bottom unit 7 has a front or front base plate 14 viewed in the depth direction of the domestic refrigerator 1, to which a rear cover 25 for covering the machine room 8 terminates to the rear. The door 9 is shown here in the closed state. In Fig. 6, the illustration of FIG. 4 is shown from below. It is looked in the context of the bottom unit 7 and in particular on the bottom plate 14. The formed in the bottom plate 14 and already mentioned downwardly open access opening 15 can be seen here with respect to their geometric configuration. It is here covered by a separate cover 16 down. As a result, the receiving shaft is closed at the bottom by this cover 16.

Subsequently, a front strip 17 separate from the ground unit 7 is arranged on the ground unit 7. This is formed in one piece and preferably made of metal. It is in particular angled, preferably L-shaped, designed and extends in particular over the entire width of the bottom unit 7. It represents a front-side outer part or final part. As a result, the bottom unit 7 is covered towards the front by this front bar 17 and also worn because the ground unit 7 is seated on an angle leg. The front strip 17 is then connected to other support elements to form a support structure.

This front strip 17 has a further opening 18 through which the opening plunger 13 can extend. This further opening 18 is dimensioned so that the opening plunger 13 can move through it with very little play.

In Fig. 7 is a view of the underside of the housing 2 and thus also on the bottom unit 7 is shown in a further perspective view. Here is the lid 16, which is screwed with screws 19 to the bottom plate 14, removed. The after bottom open access opening 15 can be seen. In addition, the cover 12 is shown, which limits the receiving shaft 20 then formed upwards and to the side each. The cover 12 is a separate component to the bottom unit 7, which is attached to the bottom plate 14. In particular, a non-destructively unsolvable fastening may be provided here, such as, for example, gluing or welding, in particular in the form of ultrasonic welding. However, it may also be provided a non-destructive detachable connection, such as a latching or screwing.

In addition, an embodiment of a door opening unit 21 is shown in FIG. This comprises a main housing 22, in which the opening plunger 13 is movably arranged. In addition, the door opening unit 21 comprises a main housing 22 separate contact housing 23, which is fixed to the back of the main housing 22, in particular it is locked. The contact housing 23 is much smaller than the main housing 22 and carries electrical connections and / or connections to the fluid line. In this context, one or more cables 24 are guided via the contact housing 23 to the main housing 22. The cables 24 may be electrical cables and / or cables in the form of hoses or conduits through which fluidic media can be routed. This door opening unit 21 is then inserted during assembly from below via the downwardly open access opening 15 in the receiving shaft 20 and then arranged there in its end position and mounted.

In Fig. 8, the bottom unit 7 is shown in a perspective view. The back cover 25 can be seen as well as the bottom plate 14. In the bottom plate 14 as shown in Fig. 8, the cover 12 is shown. This cover 12 also has an integrated cable channel 26, in which the cables 24 are guided. The cable duct 26 is also completely closed to the intermediate space 1 1, so that the thermal insulation material, which is introduced into the intermediate space 1 1, also does not reach the cables 24, which are introduced later.

The cover 12 has a front opening 27 on the front, which extends over the entire width of the cover 12. On the bottom plate 14 is integrally formed a cover strip 28 which covers this front opening 27 towards the front and thus to the door 9. Only a small passage 29 is formed in this cover strip 28, through which in turn the opening plunger 13 can pass through with little play. The door opening unit 21, which is already arranged in Fig. 8 in the receiving shaft 12, thus can not slip out of the receiving shaft 20 in the depth direction to the front, as this is prevented by this cover strip 28. This cover strip 28 is, as previously indicated, covered by the front panel 17 separate thereto front. The opening 29 and the further opening 18 are arranged in alignment with each other.

In Fig. 9, the bottom unit 7 is shown without the cover 12. The access opening 15 is completely visible here.

In Fig. 10, the door opening unit 21 is shown in a perspective view. Here, the contact housing 23 is mounted on the back of the main body 22. In addition, a heat sink 30 is arranged on this rear side of the main housing 22. In Fig. 10, the lid 16 is shown for clarity.

In Fig. 1 1, the cover 12 is shown in a perspective plan view. The integrated cable channel 26 is also shown. As can be seen, the hood-like cover 12 in the front region comprises an angular, in particular square cover 31, which has an integrated stiffening structure 32 on its outside. The stiffening structure 32 is formed in particular by line stiffeners. These line stiffeners are formed in lines which are oriented perpendicular to one another, so that a quadrangular pattern results or represents a matrix structure. As a result, in particular the roof is stiffened accordingly, so that when introducing the thermal insulation material, corresponding forces can be absorbed and no unwanted strong bulge of this roof occurs. At the back of this hood 31 then the cable channel 26 is then arranged and opening it.

In addition, the cover 12 includes a flange 33, with which the cover 12 is seated on the bottom plate 14 and thus can then be attached accordingly.

In Fig. 12, the cover 12 is shown with a view from below, in which case then the channel 26 is formed as a groove or groove. In this embodiment, it is provided that the Front opening 27 does not extend over the entire width of the cover 12, but that here also an end wall 34 is formed through which a only the opening plunger 13 passing through opening 35 is formed.

With regard to the assembly, reference is made to the following FIGS. 13 to 19. First, it is provided that the bottom unit 7 is provided with the access opening 15. This access opening 15 is formed in the bottom plate 14. In a subsequent step, the separate cover 12 is then placed from above on the bottom plate 14 and in the embodiment by non-destructive ultrasonic welding unsolvable connected. The access opening 15 is closed by the cover 12 from above. Thereby, the receiving shaft 20 is formed, which has a corresponding opening through the access opening 15 down and is limited by the walls of the cover 12.

The cover 12 is attached directly and directly behind the cover strip 28 of the bottom plate 14.

In accordance with a further assembly step, the front strip 17 is then fastened to the floor unit 7 in FIG. 14. Here, for example, a screwing be provided. In a further method step, according to FIG. 15, a pressure hose representing a cable is first preassembled in the cable duct 26. Furthermore, three electrical lines are preassembled as a further cable with a plug from the wiring harness in the cable channel 26. This pressure hose and the lines are introduced from below via the access opening 15 in the cable channel 26 and laid there. In a further subsequent assembly step, as shown in FIG. 16, a support member 36 is then inserted from below via the access opening 15 into the receiving shaft 20. This support member 36 symbolizes the door opening aid 21 during the foaming process, so that the cover 12, in particular in the region of the hood 31 is not undesirable pressed or deformed by the expanding insulating foam.

According to the further method, the pressure hose is then adjusted in abutment with the support part 36 in the illustration according to FIG. 17. In addition, the thermally insulating material is then introduced. After the introduction and in particular the curing of this insulating foam, the support member 36 is then removed from the receiving shaft 20 again. The pressure hose and the said electrical leads are then connected with the protruding ends to the contact housing 23. This is followed by threading through these cables through a cover of the contact housing 23 and then connecting to a base of the contact housing 23, which is then closed by the cover of the contact housing 23.
