EP3392580B1 - Household refrigerator having a thermal conductivity element arranged at a front flange of the inner liner - Google Patents

Description

The invention relates to a household refrigeration device with an outer housing in which an inner container of the household refrigeration device is arranged. The household refrigerator has a receiving space for food, which is limited by the walls of the inner container. The household refrigeration device furthermore has at least one separate heat-conducting element, which is arranged outside the receiving space and by means of which heat from a heat source separate from the heat-conducting element can be conducted to a condensation-critical point of the household refrigeration device.

In household refrigeration devices, it is known that, for example, moisture from the surroundings can condense in cold places of the household refrigeration device and can lead to condensation there. Such condensate water is undesirable because, on the one hand, when a user grips a component, it can cause the user to reach into the condensate water. On the other hand, it can also happen that this condensate water freezes, especially in areas of a freezer compartment of the household refrigeration device. For example, functional components such as a seal can thereby be impaired, as a result of which undesirable situations can occur precisely when a seal of this type and a door adjoining it, which seals the freezer compartment, for example. On the one hand, the door can freeze to this seal and make it difficult to open the door. If the door is then opened with a correspondingly large amount of force, the seal can be damaged. This can then lead to a sealing function that is no longer fully functional, so that heat can penetrate into the freezer compartment.

From the DE 20 2014 005 490 U1 a household refrigeration device is known in which a heat-conducting element is arranged on an inner wall section of the body or on the inner wall section of the door in order to avoid condensate within the storage space. However, this heat-conducting element is designed only as a simple rail element, which is L-shaped in cross section or is angled. It is only in the area of a contact surface of a door of an internal freezer compartment arranged on the foam side. The heat transfer is therefore limited in this embodiment.

JP 2002 243348 A discloses a refrigeration device in which a heat-conducting plate is arranged on an inner container and faces a seal, the heat-conducting plate having a higher thermal conductivity than an outer housing.

DE 10 2014 225196 A1 discloses a household appliance device which has at least one frame part element which comprises at least one groove, the frame part element having at least two cross-sectional shapes which differ substantially from one another in a partial region with respect to the main direction of extension.

JP S56 63978 U discloses a refrigerator with an outer housing and a door and with a heating element which is arranged in the vicinity of an outer housing seal

It is an object of the present invention to provide a household refrigeration device in which the heat-conducting element is designed and arranged in a more functional manner, so that the heat conduction via this heat-conducting element is improved.

This object is achieved by a domestic refrigeration appliance which has the features of claim 1.

One aspect of the invention relates to a household refrigeration device with an outer housing, in which an inner container of the household refrigeration device is arranged. The outer housing and the inner container are two separate components. A receiving space of the household refrigeration device, which is designed to receive food, is delimited by walls of the inner container. The household refrigerator also has a separate heat-conducting element. This physical and predetermined heat-conducting element is arranged outside the receiving space in the household refrigerator. The heat-conducting element is designed to conduct heat from a heat source separate from the heat-conducting element to a condensation-critical point of the household refrigeration device. The heat-conducting element is arranged on a front flange of the inner container and extends from the front flange to the condensation-critical one Job. Such a configuration enables improved heat conduction via the heat conducting element to the condensation-critical point. Because of this local connection of the heat-conducting element, namely on the front flange of the inner container, due to its local configuration on the domestic refrigeration device, the latter is at a higher temperature level than other components in the household refrigeration device. In particular, due to its local position on the domestic refrigeration appliance, the front flange is at room temperature level or essentially at room temperature level, so that a correspondingly greater amount of heat is present here, which can then be conducted at least in part to the condensation-critical point via the heat conducting element. In comparison to the prior art, this specific thermal connection point of the heat-conducting element on the front flange provides a significantly higher temperature level than the thermal coupling point for the heat-conducting element. In this way, in particular, undesired condensation or even freezing of liquid at the location critical to condensation can be avoided in an improved manner. A condensation-critical point is understood to be one where moisture can accumulate and where it can also freeze there in particular.

According to the invention, thermal insulation foam is introduced into an intermediate space between the outer housing and the inner container, and the heat-conducting element is foamed into this intermediate space.

According to the invention, the heat-conducting element is designed like a clip or like a clip. As a result, it can be attached in a particularly advantageous manner mechanically to the front flange on the one hand and to the location critical to condensation. This clasp-like configuration has a certain reversible deformation elasticity of this heat-conducting element. As a result, the heat-conducting element can already be fastened to the mentioned connection points in an advantageous manner without additional fastening means. According to the invention, a certain clinging self-retention is then achieved at these connection points.

The front flange of the inner container preferably represents a component part lying furthest forward in the depth direction of the household refrigeration appliance or a corresponding component area of the inner container. The front flange is particularly suitable for designs of inner containers in which the Receiving space, which is in particular a cooling compartment, a further receiving space, which is then a freezer compartment, is contained, offset in this depth direction to the front relative to the front side or the front flange of the internal freezer compartment. With such a design, a particularly advantageous avoidance of condensation or freezing on this front flange of the freezer compartment located in the inside of the refrigerator compartment is achieved in this type of appliance in particular. Particularly with these types of devices, this coupling of the heat-conducting element to the front flange of the inner container, which limits the cooling compartment, and thus also to the front flange of the receiving space, which is preferably designed as a cooling compartment, results in a particularly notable thermal coupling for efficient heat transfer to the condensation-critical point.

It is preferably provided that the heat-conducting element is in thermal contact with a front panel of the outer housing that is separate from the heat-conducting element and the front flange of the inner container. As a result of this further advantageous embodiment, a specific component can be provided by the front panel, which is designed to be even more efficient with regard to the heat application and thus enables a further improved thermal coupling for heat transfer from this front panel to the heat-conducting element and from there to the condensation-critical point.

It is preferably provided that the front panel, viewed in the depth direction of the household refrigeration device, covers the heat-conducting element on the front. Such a design means that when viewed from the front of the household refrigeration device and in particular also when the door is open, which delimits the receiving space, this heat-conducting element is not arranged visibly. As a result, it is concealed and protected on the one hand by the front panel, so that no undesirable influences on this heat-conducting element can occur. On the other hand, this configuration also enables a particularly stable mechanical connection of the heat-conducting element, which in turn then also enables a permanent and stable thermal connection to the front panel and, on the other hand, the heat-conducting element is arranged in a positionally secure manner. It is preferably provided that the front panel is made of metal, in particular is a sheet metal component. The advantages mentioned above can be further improved by such an advantageous embodiment. This enables in particular the very efficient application of temperature and then a correspondingly extensive and rapid heat transfer to the heat-conducting element. In addition, such a configuration is also mechanically stable.

It is preferably provided that the heat-conducting element, viewed in the depth direction of the household refrigeration device, has a front-side retaining groove which engages around the front-side front flange of the inner container. This is a further, very advantageous embodiment since it enables a very precise and mechanically stable attachment of the heat-conducting element to the front flange. As a result of this configuration, this fastening structure of the heat-conducting element, which is formed on one side, is also adapted to the conditions of the front flange, in particular its geometrical configuration, so that simple mechanical fastening is also advantageously achieved here. In particular, this front-side holding channel viewed in the depth direction is also a clip-like mounting channel. The channel shape is in deformable, in particular the channel legs of this retaining channel can be moved towards one another and moved away from one another, so that the clinging functionality is improved here.

In a further advantageous embodiment, it is provided that the holding groove has a recess on a gutter leg, into which a coupling element, which is formed on the front flange, extends. This enables a further stabilization of the mechanical fastening. In addition, a positionally accurate installation of the heat-conducting element on the front flange is thus made possible.

In particular, it is provided that the heat-conducting element has a holding web which is connected to the condensation-critical point. This retaining web is preferably designed as an elongated, rectilinear rail. In a sectional view, this holding web can be angled perpendicular to its longitudinal axis, in particular have an L-shape. This also allows it to be mechanically securely coupled to the condensation-critical point. The retaining web and the holding groove are separate sub-elements of the heat-conducting element.

In addition, this configuration also provides the largest possible contact with the condensation-critical point, so that a corresponding extensive heat transfer is made possible.

In a further advantageous embodiment it is provided that the holding web is held on an outside of the inner container. The heat-conducting element is thus arranged completely outside of the receiving space and is arranged on an outer side facing the outer housing.

It is preferably provided that the holding web is an angled web, which is arranged at a step that represents or has a condensation-critical point on the outside of the inner container and is arranged around this step. In particular, this retaining web is arranged clamped on this step. This clamping effect is achieved in particular when the heat-conducting element is elastically deformable in itself, in particular in its clasp-like configuration.

Advantageously, the step on the outside of the inner container forms a front of a freezer compartment area which is formed on the inside in the receiving space. Viewed in the depth direction of the household refrigeration device, this step, which is integrated in the inner container, on the inside of the inner container represents a front side of this freezer compartment or a front flange of the freezer compartment. Viewed in the depth direction forward, the inner container extends even further forward, so that a corresponding volume of the this freezer compartment receiving or having receiving space is formed. This step forms a stop on an inner side of the inner container facing the receiving space, against which a door closing the freezer compartment rests when this door is closed. In particular, a seal can be arranged on this inside of the step, against which this door, which closes the internal freezer compartment, bears in the closed state. The seal can be arranged on the door or the front of this step.

It is preferably provided that the holding groove and the holding web of the heat-conducting element are connected to at least one connecting bracket of the heat-conducting element. In particular, the holding groove extends as a straight shaped component. Correspondingly, an embodiment of the holding web is advantageous. In particular, the holding groove and the holding web extend at a distance from one another and are parallel or essentially parallel to one another with their longitudinal axes. In this context, the connecting bracket is oriented quasi perpendicularly or essentially perpendicularly to these longitudinal extensions of the holding web and the holding groove. In particular, this connecting bracket is designed as a strip-like element. With such a relatively filigree design, the heat-conducting element is designed to be very light-weight and yet provided in a highly functional manner. In particular, the elastic deformability of the heat-conducting element is particularly advantageously made possible by this configuration. In particular, the connecting bracket is designed as an expansion bracket. This means that it is deformable in itself, in particular also due to its geometric configuration, which is particularly uneven, to a certain extent also variable in length. If this basic position or basic shape, in which this connecting bracket is uneven, is deformed in the direction of a flat shape, this increase in length occurs, as a result of which the holding channel and the holding web can then be removed from one another and the entire heat-conducting element virtually spreads out. Due to the basic shape of the connecting bracket, a shortening takes place when the connecting bracket is automatically returned to its basic shape, as a result of which the holding channel and the retaining web are automatically moved towards one another again. As a result, the clamping effect or the clamping effect of the heat-conducting element is also provided functionally.

Viewed in the depth direction, the front flange of the inner container delimiting the receiving space and the further front flange of the inner container delimiting the freezer compartment are spaced apart and the further front flange is arranged on the inside in the receiving space, which in particular forms the cooling compartment. The two front flanges are made in one piece with the inner container.

The heat-conducting element is advantageously formed in one piece. A corresponding three-dimensional structure can be formed or folded from a blank that is produced by appropriate punching and the like.

The heat-conducting element preferably has at least two, preferably three such connecting brackets. In particular, viewed in the longitudinal direction of the holding groove and in the longitudinal direction of the holding web, a first connecting bracket is connected to first ends of the holding groove and the holding web, a second connecting bracket is connected to the opposite ends of the holding groove and the holding web, and a third connecting bracket between the first and the second connecting bracket arranged and connected to the holding trough and the holding web, in particular approximately in the middle of the lengths of the holding web and the holding trough connected to them.

In particular in the exemplary embodiment already described, in which a freezer compartment is formed on the inside in a refrigerator compartment, the warm ambient air condenses in the temperature transition to the freezer compartment on the seal of the front flange of the freezer compartment, which is preferably arranged there on the inside. In order to avoid such ice formation, the corresponding heat-conducting element is formed in the proposed aspects and is coupled to the specific thermal connection points.

It can be provided that the heat-conducting element is additionally fastened to at least one of the connection points using a fastening means, for example an adhesive tape.

Identical or functionally identical elements are provided with the same reference symbols in the figures.

In Fig. 1 is a perspective view of a household refrigerator 1 is shown, which is designed for storing and preserving food. The household refrigerator 1 is designed here as a fridge-freezer. The household refrigerator 1 has a housing 2. The housing 2 comprises an outer housing 3, which closes off the household refrigerator 1 on the outside. In addition, the housing 2 comprises an inner container 4. The inner container 4 is accommodated in the outer housing 3 and a separate component therefor. A thermal insulation material, in particular an insulation foam, is introduced into an intermediate space 5 between the inner container 4 and the outer housing 3.

Walls of the inner container 4 delimit a receiving space 6, which is a cooling compartment here. In addition, the household refrigerator 1 has a freezer compartment 7, which is designed as an internal freezer compartment 7 in the refrigerator compartment 6. The freezer compartment 7 can be closed by a separate door 8. With such a configuration, the door 8 is only accessible if an entire door 9, which covers the entire receiving space or the refrigerator compartment 6 closes at the front, is open. As can be seen in the exemplary embodiment shown, the freezer compartment 7 is formed on the inside in the upper region of the cooling compartment 6 in the height direction (y direction). In addition, it can be seen that in the depth direction (z direction), the freezer compartment 7 is arranged offset to the rear in the cooling compartment 6, so that the inner container 4 extends forwardly beyond this freezer compartment 6.

When viewed in the depth direction, the inner container 4 has a front front flange 10, which in particular is circumferential and thus also forms a boundary frame for a loading opening of the cooling compartment 6. A seal 11 can be arranged on this front flange 10 of the inner container 4, which thus forms the front end of the inner container 4, viewed in the depth direction, against which the door 9 then bears in the closed state.

As can be seen, the front flange 10 is viewed in the depth direction with respect to the door 8 and thus also with respect to one in Fig. 1 not to be recognized further front flange of the freezer compartment 7 arranged offset to the front.

In particular, it is provided that the household refrigeration appliance 1 has a front panel 12 which is separate from this front flange 10 and is only shown schematically here and is symbolically provided with the reference number 12. This front panel 12 is preferably made of metal and is in particular a sheet metal component. In contrast, the inner container 4 is preferably a one-piece, deep-drawn plastic component.

As also in Fig. 1 cannot be seen, this further front flange, which, viewed in the depth direction, delimits the freezer compartment 7 on the front side and thus limits a loading opening of the freezer compartment 7 in a quasi-frame-like manner, has a contact surface against which the door 8 bears in the closed state. A further seal can preferably be arranged on this front flange of the freezer compartment 7 or on the door 8, against which the door 8 then lies in the closed state. It is precisely this area of this front flange of the freezer compartment 7 that is a critical point in terms of condensation. There, due to the ambient air entering the refrigerator compartment 6 when the door 9 is open, moisture can form which can then also freeze. In particular, this can take place if the door 8 is then also opened, if appropriate, and a corresponding one Temperature gradient occurs between the colder freezer compartment 7 and the warmer refrigerator compartment 6.

In order to avoid such condensation and, in particular, freezing of this moisture in the region of this front flange of the freezer compartment 7, the household refrigeration device 1 has at least one specifically designed and locally specifically coupled separate heat-conducting element 13, such as an exemplary embodiment in a perspective view in FIG Fig. 2 is shown. This heat-conducting element 13 has already been completed in its shape in the unassembled state and is predefined accordingly. The heat-conducting element 13 is thus a molded component and not a heat-conducting paste or the like. The heat-conducting element 13 is preferably formed in one piece and in particular made of metal. The heat-conducting element 13 is designed like a clip or like a clip. In the embodiment shown, it has a holding groove 14 which is straight and has a longitudinal axis A. This retaining channel 14 is as it were when viewed in accordance with Fig. 2 open towards the bottom and has two gutter legs 15 and 16. The opening of this holding groove 14 is thus downward, so that this holding groove 14 can be clipped onto a coupling point from above. In particular, the heat-conducting element 13 is thermally connected to this holding groove 14 with the front flange 10, in particular attached to it. In particular, the heat-conducting element 13 is thermally coupled to the holding groove 14 with the front panel 12, in particular is arranged so as to lie directly against it. It is then a direct mechanical and thus also a direct thermal connection between the heat-conducting element 13, in particular the holding channel 14, with this front panel 12.

As can be seen, this holding groove 14 has a cutout 17 into which a coupling element formed on the front panel 12 can extend in the assembled state. However, this coupling element can also be formed on the front flange 10.

In addition to this holding channel 14, the heat-conducting element 13 has a holding web 18 that is separate from it. This is also straight and has a longitudinal axis B. In particular, this retaining web 18 is uneven, in particular as an angled one Rail formed. In particular, this holding web 18 has an L shape in a sectional illustration perpendicular to its longitudinal axis B.

As can be seen, the holding groove 14 and the holding web 18 are spaced apart and arranged parallel or essentially parallel to one another.

The heat-conducting element 13 also has at least one connecting bracket 19, in the exemplary embodiment three connecting brackets 19. The connecting brackets 19 are uneven, in particular strip-like components, which connect the holding channel 14 and the holding web 18. Due to their uneven shape, in particular an angled configuration, they also have a certain elasticity so that they can be reversibly changed in length in the direction of their longitudinal extensions if this unevenness is increased or decreased. As a result, a certain elasticity of deformation of the heat-conducting element 13 is also formed, so that in this connection the holding groove 14 and the holding web 18 can accordingly move away from one another or move towards one another. This also enables the clip-like or clip-like functionality of the heat-conducting element 13. In particular, the holding web 18 is designed in the context of the mechanical and then also thermal coupling with a further point of the household refrigeration device 1, in particular with the condensation-critical point.

In Fig. 3 is shown in a partial perspective view of the household refrigerator 1 with sub-components. In particular, a view of the outer side 20 of the inner container 4 facing away from the freezer compartment 7 is shown, this partial region of the inner container 4, which is shown in FIG Fig. 3 is shown are those walls that delimit the freezer compartment 7.

In the Fig. 3 can already be seen that the heat-conducting element 13 as shown in FIG Fig. 2 is installed on this outside 20 of the inner container 4. For this purpose, it can be seen that the holding web 18 is arranged adjacent to a step 21, which is formed on this outer side 20. This stage 21 forms the transition from the freezer compartment 7 to the refrigerator compartment 6. In particular, a collar 22 of this stage 21 is shown, which on one in Fig. 3 The inside, not to be seen, which lies opposite this outside 20, forms the front flange of the freezer compartment 7. In addition, in Fig. 3 can also be seen that the retaining groove 14 bears against the front flange 10 or is in particular attached. In addition, in Fig. 3 the front panel 12, which is separate from the front flange 10 and has already been mentioned, is also shown with a panel part 23, which is shown here in the not yet assembled state. This front panel 12 is then in the assembled state with the holding channel 14 in particular in direct contact and completely covers the heat-conducting element 13, in particular the retaining channel 14 when viewed from the front. As can be seen, the heat-conducting element 13, viewed in the depth direction, extends forwards over the front flange of the freezer compartment 7 to the front end of the inner container 4, which is formed by the front flange 10.

It is in Fig. 3 it can also be seen that this heat-conducting element 13 thus rests like a clip or clamp-like between two coupling points arranged at different depths, viewed in the depth direction of the household refrigeration device. In particular, this step 21 and in particular this collar 22 thus represent the condensation-critical point on the side facing the cooling compartment 6 and thus on the inside of this inner container 4 opposite the outside 20. The front flange 10, however, and in particular, if it is present, the front panel 12 , represent a heat source via which heat is transferred to the heat-conducting element 13 and can then be transferred from this to this condensation-critical point 24 via this collar 22.

In the finished state, this heat-conducting element 13 is then also surrounded by the insulation foam already mentioned, so that it is embedded accordingly in this intermediate space 5.

In Fig. 4 is in a vertical sectional view (section plane is the yz plane) of the household refrigerator 1 according to Fig. 1 in the upper area, namely the freezer compartment 7 and shown with the door 9 closed.

As in Fig. 4 can also be seen, a seal 25 is arranged on the already mentioned, further front flange 28, which delimits the freezer compartment 7 at the front or frames a loading opening of the freezer compartment 7. The seal 25 can also be arranged on the door 8.

As in Fig. 4 can be seen explicitly, the heat-conducting element 13 thus extends, as it were, from this front-side region of the freezer compartment 7 in the depth direction to the front towards the door 9 and is connected in particular to this front front flange 10 with the holding groove 14, in particular also thermally coupled to the front panel 12 , especially directly connected to it.

As in Fig. 4 can also be seen, the front flanges 10 and 28, viewed in the depth direction of the household refrigeration device 1, are arranged at a distance from one another and the further front flange 28 is embodied offset to the rear in the cooling compartment 6.

In Fig. 5 is an enlarged view of a partial section of the view in Fig. 4 shown, here this enlarged view is shown in the region of the heat-conducting element 13. As especially in Fig. 5 It can be seen that the retaining web 18, which is L-shaped in this cross-section, lies on the step 21 over a large area, in particular over the entire area, on the outside 20. The angled and angled away from the holding web 18 shape of the connecting bracket 19 can be seen.

In addition, the state of the holding groove 14 which is plugged onto the front flange 10 can also be seen.

In this sectional view it can also be seen that a coupling element 26 extends through the recess 17. The coupling element 26, which is integrally molded on the front flange 24 in particular, thus extends in the depth direction to the rear into this recess 17. As in the illustration in Fig. 5 can be seen, the connecting bracket 19 has a trapezoidal configuration.

In addition, it can be seen that this connecting bracket 19 is in particular spaced apart and thus also arranged in a contactless manner with respect to the outside 20 of the inner container 4.

As beyond in Fig. 6 , in which a perspective sectional view of the view in Fig. 5 is shown, can be seen, is on the retaining groove 14, in particular on the retaining web 18 facing and thus in the depth direction rear gutter leg 16 at least one tab 27 is formed in one piece, which in the assembled state can also rest on the outside 20. Due to the curved shape, a certain elastic spring effect is achieved in order to enable appropriate elasticity of movement.
