EP3030853B1 - Domestic refrigeration appliance with an inner case and removable guide rails for a tray arranged therein - Google Patents

Description

The invention relates to a household refrigerating appliance with an inner container which delimits an inner space for receiving food, and which has a guide device with which a tray which can be removed from the inner space can be moved.

Domestic refrigerators, such as a refrigerator, are known from the prior art, in which a shell or a drawer is arranged in an interior space for receiving food in a lower region. This can absorb food and can be pushed into the interior and pulled out. Usually, such a shell is arranged at the lower region of the inner container. For horizontal displacement, a guide device is provided. For example, integrated components for guiding can be provided here on the inner container. This may possibly increase the complexity of the shape of this inner container and make it difficult to produce.

In addition, the variability in the use and placement of the inner container is limited by such an integrated design of a guide device. Even with a removed shell, this makes it difficult to assemble with other removable components, since the integrated guide elements extend into the interior space and thereby possibly hinder, in order then to introduce other components as a replacement.

In addition, due to the design of these integrated guide elements in the area near the floor, the cleanability may also be restricted or expensive.

In addition, embodiments of such household refrigerators are known in which no guide device is provided, but a corresponding shell can only be placed on the bottom of the inner container and moved along the ground. This may undesirably affect the soil, For example, be scratched. Especially with extensive placement of such a shell of food, which then also results in a correspondingly higher weight, such unwanted deterioration of the soil is then seen at least in the long term. Also, in such an embodiment, the ease of movement of a sliding movement is limited and a user must bring a relatively higher force in case of possibly extensive placement of this shell with food to then move the shell can.

The EP 2 594 878 A2 discloses a refrigerator. The cooling device comprises a first rail which is installed in a depression of a bottom of a storage compartment and a corresponding second rail which is arranged at the bottom of a drawer.

The EP 2 581 694 A2 discloses a refrigerator having storage containers disposed on a shelf to enhance space utilization in the refrigerator. The refrigerator has a number of shelves, which are removable resting on support structures. On two sides of the shelves serving as a guide receiving devices for appropriate projections of the storage container are arranged.

The DE 10 2010 013 701 A1 discloses a pull-out system for a refrigerator and / or freezer with a guide means for guiding a pull-out component and with a transfer means, which preferably serves for damped and / or braked transfer of an extendable component into or out of an end position.

It is an object of the present invention to provide a household refrigerator, which is improved in terms of manageability and placement with a shell.

This object is achieved by a household refrigerator according to claim 1. Preferred embodiments are subject of the dependent claims.

A domestic refrigeration appliance according to the invention comprises an inner container which delimits an interior for receiving food. The domestic refrigerator also includes a guide device with which a removable from the interior Shell, in which food can be introduced for storage, is movable. This shell is thus a food intake bowl. The interior of the household refrigerator is accordingly a food intake interior.

An essential idea of the invention is to be seen in that the guide device has two guide rails, which are arranged non-destructively releasably on an inner side of the inner container. By such a configuration, it is possible that a said shell can be guided smoothly and purposefully and thus the corresponding movement can be achieved user friendly. This also avoids an undesired impairment of the inner container during a relative movement between the shell and the inner container. It is also particularly advantageous that thereby the guide rails can be easily cleaned due to their removability. Not least, a more variable use of this partial volume of the interior, in which the shell can be introduced, achieved by such a reversibly repeatable removal option. The assembly with other components is then possible and with removed guide rails also achieved an alternative use of this partial volume of the interior.

In an advantageous embodiment, the inner container has a bottom and at its opposite edges adjoining vertical side walls. In each case a guide rail is arranged at transition regions between the bottom and a side wall. By such a specified positional arrangement of the guide rails in lower corner regions between a bottom and a side wall and a stable and secure positioning is possible. In addition, the entire width of the interior is utilized by such a configuration, so that a correspondingly wide shell can be used. This, in turn, then has a greater useful volume to be stocked with food.

It is preferably provided that at least one guide rail extends over at least 90% of the depth of the interior. By means of such an extent extent in this depth direction, a corresponding guidance of the shell is made possible virtually over the entire depth. As a result, the movement guidance is very much along its entire path defined predetermined and undesirable spreading or jamming or even required by a user threading midway such a movement in the interior or from the interior is thereby avoided.

In an advantageous embodiment, the two guide rails are designed to be identical, so that the previously mentioned and possibly also subsequent explanations for at least one of these guide rails then apply to both.

It is provided that at least one guide rail is fastened to a rear wall of the inner container. This improves position fixation and positional adjustment. Especially with a heavier shell, which is then possibly also circumferentially equipped with food, this remains at least one guide rail then very accurate location and stable in position during the movement of the shell. Also, this remains the smooth over the entire way, jerk-free and in particular anti-displacement motion control of the shell.

It is provided that the rear wall of the inner container has a bulge to the rear, in which an engagement element of a guide rail extends. This bulge is thus in particular turned away from the interior facing outward. The position fixation of a guide rail in the finally introduced end position is thereby advantageously supported again. Just a shift in the width direction of the household refrigeration device is thereby particularly effectively prevented, so that the above-mentioned advantages in terms of motion control of the shell are again positively supported.

It is preferably provided that the engagement element of the guide rail is a movable tab, which rests in the mounted state of a guide rail on a ceiling of the bulge. As a result, an undesirable vertical movement of this guide rail is prevented. Advantageously, it is provided that the tab is biased in the assembled end state of the guide rail on the inner container upwards, so that this vertical position fixation favors again.

It is preferably provided that at least one guide rail has a plate-like abutment part on a rear end associated with the rear wall, which in the mounted state of the guide rail rests against an inner side of the rear wall. In particular, it is provided that this plate-like stop member is arranged at a distance from the tab and above the tab and viewed towards the rear in the depth direction of the household refrigerating appliance designed to be shorter tab. As a result, the position centering and accurate positioning of a guide rail in the interior is advantageously supported.

In particular, it is provided that this plate-like stop member rests in the mounted end state of the guide rails above the bulge on the inside of the rear wall. A diverse mechanical contacting and interaction of the guide rails with their individual components with the inner container, in particular the bulge on the one hand and the inside of the rear wall on the other hand is achieved. The mechanical meshing is thereby made possible in a particularly advantageous manner and the positional arrangement is achieved. In addition, the assembly and disassembly of a guide rail is very simple by such a configuration and quickly possible, on the other hand, however, given a sufficiently reliable and secure fit of this guide rail in the inner container.

It is preferably provided that at least one guide rail is fastened to a bottom of the inner container. This is especially given in addition to the attachment of a guide rail on the rear wall of the inner container. Viewed over the entire length of a guide rail thus at least these two attachment areas are provided. As a result, the position fixation can be further improved.

In particular, it is provided that the bottom of the inner container has a depression and an insertion channel for a fastener is formed down to a recess bottom, so that the fastener in the assembled state under a top of the floor, in particular at the level of the recess bottom or lower, is arranged. This means that viewed in the vertical direction, the height position of this fastener is mounted in the mounted end state such that it does not stand in the interior, preferably even does not stand in the recess of the soil. As a result, the depression in the bottom can be used to accommodate further components, so that here the possibility of fixing and fixing the position, in particular also of a guide rail, can again be favored.

In addition, by such a recess, the recording option of other functional parts allows, so that they can be arranged at least partially submerged. As a result, no undesired installation space of the interior is restricted here, and, on the other hand, if appropriate, a positionally reliable arrangement of such a functional part is also made possible.

It is preferably provided that at least one guide rail on a guide rail bottom has a recess which is arranged in the mounted state in a recess in a bottom of the inner container. The achievable advantages have already been mentioned above.

Preferably, it is provided that in the recess in the guide rail floor an upwardly out of the recess and out of the depression non-destructive detachable roller is arranged. Such a roller can in particular be such a functional part as mentioned above. By such a partially sunk arrangement of a roller then the motion control of the shell can be further improved and in particular designed very smoothly.

It is preferably provided that the recess for the guide rail bottom is formed in a front third of the extent extent of the guide rail viewed in the depth direction of the household appliance. Especially with very large-sized guide rails is thus in conjunction with a preferably existing rear connection to the inner container respectively at the two ends of the guide rail allows a very close attachment and position-secure connection. In addition, just by this local configuration, a positional arrangement of this releasable roller is reached, which engages already at the beginning of the coupling and movement of the shell when inserted into the interior and thus the entire smooth rolled movement of this shell substantially over the entire path of movement of the shell in the Interior allows.

It is preferably provided that at least one guide rail on a guide rail bottom at a rear end of a guideway has a ramp-like Führungsbahnerhöhung. The guideway thus forms that portion of the guide rail on which the shell rests directly contacting and can be moved relative thereto. By this ramp-like Führungsbahnerhöhung an increase of at least the rear end of the shell in the reached inserted end position in the interior is made possible. A slip-proof final positioning is favored thereby. By this increase, the extraction of the shell from the interior is then promoted, starting from the reached inserted end position of the shell, so that a smoother start of extraction is achieved for a user. The guide rail elevation comprises in particular a ramp and a subsequent support plateau.

It is preferably provided that the shell on an underside of a shell bottom on opposite sides in a rear third of the extent extent of the shell in the depth direction of the domestic refrigeration device viewed in each case at least one shell roll which when moving the shell in guideways of Roll along guide rails. In addition to the device side and thus in particular the inner side of the container or guide rail side rollers also these shell rollers are then provided. As a result, the movement guidance of the shell is favored again.

A very preferred embodiment is the fact that viewed in the width direction of the household refrigerating appliance, the shell rollers and the ramp-like Führungsbahnerhöhungen are each arranged offset from one another. This is in particular designed such that in the inserted end position of the shell in the interior of the shell rollers are lifted from the guideway and the underside of the shell bottom is seated on the Führungsbahnerhöhungen. Especially with circumferentially loaded shell is thus exerted after the introduction of the shell into the interior and the reaching of the end position no permanent weight load on these shell rollers. Rather, they are preferably completely relieved, so that the rollers and in particular the roller bearings are not undesirable worn.

In an advantageous embodiment, it is provided that the guide rail on the path of movement of the shell and thus in particular on a guideway has an elevation upwards, which represents a pull-out stop. Such an extension stop element is preferably formed viewed in a front third of the guide rail in the depth direction of the household refrigerating appliance. This pull-out stop element, viewed in this depth direction, is preferably arranged at a distance behind an above-mentioned roller. By this embodiment, an extract position of the shell can be achieved, which requires no removal and desired, but only the viewing of the shell from above and the food introduced therein also allows for removal without the shell would move further forward and then fall out would. This pull-out stop element is preferably also designed as a tilt protection element, optionally with at least one other component of the guide rail. As a result, an undesirable tilting tendency of the shell forward down below can be prevented if it is already pulled out relatively far.

Preferably, the guide rails are made of plastic. As a result, they are designed very low weight and relatively easy to manufacture, for example, as an injection molded part feasible.

By the rear connection of a guide rail to the rear wall, in particular the above-mentioned advantageous specific embodiments, can also be achieved by such a mechanical coupling with the inner container that forces acting directly on the shell guide or the guide rails, in the housing and thus in particular can be transferred to an inner container. Such an embodiment can thus save an explicit screw connection in the rear region of the guide rails with the inner container.

Preferably, a guide rail has, in addition to a guide rail bottom, a vertical guide rail side wall which, in the assembled state, faces a guide rail in the inner container of a vertical side wall, in particular bears against it. As a result, at least over the entire length of such a guide rail, an angled cross-section profile, in particular an L-like profile, achieved, whereby the support on the floor and on the side wall is favored again. In a further advantageous embodiment, at an upper edge of such a vertical guide rail side wall, a horizontal web projecting inwards and thus away from a vertical side wall of the inner container is formed. Through this, the movement guidance of the shell is again favored and stabilized, since the shell is held again in the width direction of the household refrigerator. In addition, by such a configuration, the guide rail is mechanically stabilized in itself, so that the torsional rigidity is improved.

It is preferably provided that the pull-out stop element already mentioned above in the depth direction of the household refrigerating appliance is arranged at the level or in front of a front end of this vertical guide rail side wall and / or this horizontal bar. This means that the pull-out stop element, viewed in the direction of the depth, is arranged on the side facing away from a rear wall of the inner container.

In the figures, identical or functionally identical elements are provided with the same reference numerals.

In Fig. 1 is shown in an exemplary representation of a household refrigerator 1, which is designed as a fridge-freezer combination device. However, the household refrigerator 1 may also be designed as a cooling device as such. The household refrigerator 1 comprises a body or a housing 2, which surrounds an inner container 3. The inner container 3 defines with its walls a first inner space, which is a cooling space 4, and a second inner space, separated therefrom, which is a freezing space 5. The cooling space 4 is generally used for frost-free cooling of refrigerated goods, preferably at temperatures between + 4 ° C and + 8 ° C. However, the refrigerated space 4 can also be designed as a zero-degree compartment, in particular for keeping fruit or vegetables fresh. The refrigerator compartment 4 is accessible when the door 6 is open, which closes the refrigerator compartment 4 at the front.

The freezer compartment 5 is generally used for freezing frozen food at, for example, -18 ° C. The freezer compartment 5 is accessible with the freezer compartment door 7 open.

In the refrigerator 4, a refrigerated goods or fresh food container 8 may be mounted extendable, which is closed by means of a lid 9 mounted above the fresh food container 8. As shown, an additional cover 10, for example in the form of a glass shelf, can be arranged above the lid 9.

The inner container 3 has two vertical side walls 3a and 3b. It also has a back wall 3c, a ceiling wall 3d and a bottom 3e.

Viewed in the width direction and thus in the x direction, the bottom 3e edges 11 and 12, to which the opposite vertical side walls 3a and 3b open. As a result, transition areas 13 and 14 are formed at these locations.

The household refrigerator 1 further comprises a food receiving tray 15, which may be a drawer. The shell 15 may be provided in addition to or instead of the fresh food container 8. It can be provided that in the drawer 8, an ambient humidity is adjustable, which corresponds to the ambient humidity in the refrigerator 4 outside of the fresh food container 8. However, it can also be provided that in the shell 15, an ambient humidity can be adjusted, which is different from the cooling chamber 4 and, for example, equal to the ambient humidity in the fresh food container 8.

The shell 15 can be pulled out and inserted horizontally in the depth direction and thus in the z-direction. The shell 15 is intended for receiving and storing food.

The shell 15 is provided with a guiding device 16 as shown in FIG Fig. 2 is shown in subcomponents, motion-guided. For this purpose, the guide device 16 at the opposite transition regions 13 and 14 each have a guide rail, of which in Fig. 2 only the guide rail 17 is shown. The two guide rails, of which only the guide rail 17 will be explained below, since the opposite guide rail is identical in construction, are detachable from the inner container 3 in a non-destructively detachable manner and can be placed again. The guide rail 17 extends in the depth direction and thus in the z-direction over at least 90% of the depth of the cooling space 4th

The guide rail 17 includes a guide rail bottom 18. At a rear end of the guide rail 17, a stop 19 is formed. This is in the assembled final state on the rear wall 3c or on the inside 32 at. In addition, the guide rail 17 comprises a vertical guide rail side wall 20, which is arranged on the guide rail bottom 18 and the adjacent vertical side wall 3a of the inner container 3 faces facing, in particular abuts when the guide rail 17 is arranged in the final assembled state in the inner container 3.

At a viewed in the vertical direction and thus in the y-direction upper end of this guide rail side wall 20, a horizontal web 21 is formed extending from the Side wall 3a facing away from the interior 3 extends. In this regard, however, it is shorter in the width direction than the guide rail bottom 18. In addition, the guide rail side wall 20 and the web 21 are formed shorter than the guide rail bottom 18th

On the guide rail bottom 18 is a ramp-like Führungsbahnerhöhung 22 is formed in a rear region and the stop 19 opening, which is a guideway 23 as part of belonging. On the guide track 23, the shell 15 is guided during horizontal displacement. This Führungsbahnerhöhung 22 thus represents a pedestal on which the shell 15 is seated in the fully inserted end position.

On the guide rail bottom 18, a pull-out stop element 24 is also formed beyond. This is raised above at the top, so that a partially extended intermediate position of the shell 15 can be stopped and forward extension is prevented. As a result, an undesired slipping out of the shell 15 can be avoided. In addition, it is preferably provided that the pull-out stop element 24 is designed in particular in interaction with the web 21 as a tilt protection device. The shell 15 can then not tilt over in this partially pulled position undesirably far forward and down.

In addition, the guide rail 17 includes a front roller 25, whose positional arrangement and configuration in the following Fig. 3 explained in more detail and shown.

In Fig. 3 is an enlarged perspective sectional view of the portion I in Fig. 2 shown.

This roller 25 is rotatably mounted about an axis A, which extends horizontally and thus in the x direction. This axis A extends laterally toward the side wall 3a and is held fixed in particular in the guide rail 17 and / or in the side wall 3a. This roller 25 with the axis A is also non-destructive solvable mountable and disassemblable so that it is reversibly repeatable removable and attachable again.

As from the illustration in Fig. 2 and Fig. 3 can be seen, the impeller 25 is partially sunk arranged in the guide rail bottom 18. This includes a recess 26, in which this roller 25 is embedded. The recess 26 is also arranged in a recess 27 of the bottom 3e, in particular accurately positioned and fixed in position therein. This recess 27 has on an indentation bottom 28 an insertion channel 29 for a fastening element 30. The fastener 30 is here in particular a screw. The extent of the insertion channel 29 in the y-direction is dimensioned such that in the final assembled state of the fastening element 30, this does not project beyond a height level of the recess bottom 28 in the vertical direction.

Also, the recess 26 in the guide rail bottom 18 has a continuous recess through which the fastener 30 is accessible and thereby is correspondingly assembled and disassembled. By this embodiment, the guide rail 17 is attached to the bottom 3e non-destructively releasably. This recess 26 of the guide rail 17 is formed in a front third of the extent extent of this guide rail 17 viewed in the depth direction of the household refrigerating appliance 1.

Moreover, according to the present invention, the guide rail 17 is also fixed to the rear wall 3c. For this purpose, as shown in Fig. 4 , which is an enlarged perspective sectional view of the view in FIG Fig. 2 In the region of the stop 19, a bulge 31 is formed on the rear wall 3c. This bulge 31 thus extends to the side facing away from the cooling chamber 4 to the outside and thus represents an outward bulge. In this engages the guide rail 17 a. For this purpose, a strip-like or plate-like engagement element 33 is formed in the rear stop 19. This is elastically deformable in the vertical direction. In the mounted final state of the guide rail 17 shown, this engagement element 33 is disposed on a ceiling 34 of the bulge 31 in particular biased fitting. This engagement element 33 is in particular a tab.

In addition, a plate-like stop member 35 is formed in the stop 19. This is positioned at a distance from the engagement element 33 and formed and arranged above this engagement element 33, in particular designed to extend substantially parallel thereto. In the final assembled state of the guide rail 17, it is with its free rear edge on the inside 32 fitting and thus also positioned above and outside of the bulge 31 on the inside 32.

In Fig. 5 is the representation according to Fig. 4 shown in a different perspective. The ramp-like Führungsbahnerhöhung 22 is also shown enlarged and its course and the geometric design illustrated.

In Fig. 6 is a partial side view of the household refrigerator 1 shown in a schematic side view. In this case, the shell 15 is shown in an intermediate position between a fully inserted and an extended position. The shell 15 comprises a shell bottom 36. At this shell bottom 36 shell wheels 37 are arranged in a rear third of the extent extent of the shell 15, wherein in Fig. 6 only one shell wheel 37 can be seen. The two shell wheels are arranged on the shell 15 and thus also on the shell bottom 36 so that they roll in the width direction (x direction) along the guide tracks 23 of the guide rails 17, respectively.

As in Fig. 6 can be seen running these shell rollers 37 on the guideway 23 as long as the final inserted end position of the shell 15 in the cooling chamber 4 is not reached yet.

This is in Fig. 7 a representation shown in which this shell 15 is then shown in the inserted end position. As can be seen thereby, the tray bottom 36 is then on the rear part, a support plateau 22b, the ramp-like Führungsbahnerhöhung 22 after he was raised above a Auffahrschräge 22a. This Führungsbahnerhöhung 22 is designed so that in this end position according to Fig. 7 then the shell rollers 37 are arranged without weight load, in particular lifted from the guideway 23 are positioned.

An effect of the weight of the shell 15 on the shell rollers 37 is prevented. <B> LIST OF REFERENCES </ b> 1 Household refrigerator 22b edition platform 2 casing 23 guideway 3 inner container 24 Drawer stop element 3a Vertical sidewall 25 caster 3b Vertical sidewall 26 deepening 3c rear wall 27 deepening 3d ceiling wall 28 well bottom 3e ground 29 introduction channel 4 refrigerator 30 fastener 5 freezer 31 bulge 6 door 32 inside 7 Freezer door 33 engaging member 8th Cling container 34 ceiling 9 cover 35 stop part 10 cover 36 shell bottom 11 edge 37 cup wheel 12 edge 13 Transition area 14 Transition area 15 Bowl 16 guiding device 17 guide rail eighteen Guide rail floor 19 attack 20 Guide rail side wall 21 web 22 Guideway increase 22a Auffahrschräge
