Description

The invention relates to a household appliance, in particular a household refrigerator, with a body and a closure element which closes a storage space located in the body and is articulated to the body by means of at least one hinge, the hinge comprising a body-side hinge part which is attached to a flat contact surface on the Body is attached.

Such a household appliance can be, for example, a refrigerator such as a refrigerator, a freezer or a fridge-freezer combination.

The closure element, for example a door, is usually articulated to the body, i.e. attached to it, by means of two hinges which are spaced apart along a pivot axis of the closure element. The closure element can be pivoted about the pivot axis in order to enable access to the storage space or to close the storage space. A seal, which is often arranged on the closure element, seals the storage space in a closed state of the closure element. In the case of built-in household appliances, a furniture panel is also arranged on an outside of the closure element. A precise alignment of the closure element with respect to the body in the closed state is necessary on the one hand in order to enable optimal sealing in the closed state of the closure element. On the other hand, in built-in household appliances in particular, precise alignment of the closure element with respect to the body is necessary in order to achieve uniform gaps between the closure element (in particular in the closed state) and adjacent furniture.

To enable a precise alignment of the closure element with respect to the body and at the same time to transfer the necessary forces, the hinges typically have a flat contact surface for contact with the body and are typically fastened to the body by means of two screws.

The object of the present invention is to improve a household appliance of the generic type and to provide an improved hinge for a household appliance.

This object is achieved according to the independent claims. Accordingly, a household appliance, in particular a household refrigerator, has a body and a closure element which closes a storage space located in the body and is articulated to the body by means of at least one hinge, the hinge comprising a body-side hinge part which is attached to a flat contact surface is attached to the body, it is provided that the body has a positioning element which is offset with respect to the bearing surface along a direction running perpendicular to the bearing surface and which forms a form-fitting connection with the body-side hinge part.

The closure element can in particular be articulated to the body by two separate hinges. The closure element can be pivoted along a pivot axis between an open position and a closed position. The storage room is accessible in the open position. In the closed position, the storage room is locked. In particular, the storage space is completely delimited by the body and the closure element in the closed position.

The hinge can be made in one piece or in several pieces. In any case, the hinge comprises a hinge part, namely the body-side hinge part, which is fastened to the body. This hinge part can in particular be screwed to the body, for example by means of two screws.

The hinge part is attached to a flat contact surface of the body. The contact surface of the body represents in particular that surface which is in direct contact with the hinge, in particular the hinge part on the body side.

The present invention is based on the knowledge that a conventional fastening of the hinge to the flat contact surface, for example by means of a screw connection, basically provides the necessary strength of the connection. To achieve the necessary precision when aligning the closure element with respect to the body, however, a precise arrangement of screw holes in the contact surface on the one hand and the hinge part on the other hand is necessary. In addition, precise alignment of the hinge with respect to the body is necessary when installing the hinge.

Instead of fastening the hinge exclusively via the flat contact surface of the body, the invention proposes additionally providing a form-fitting connection. For this purpose, a positioning element is arranged on the carcass which forms the positive connection with the carcass-side hinge part, in particular a counter-positioning element of the carcass-side hinge part. The positioning element is offset with respect to a plane comprising the contact surface - and thus with respect to the contact surface - along a direction running perpendicular to the contact surface.

The additional, form-fitting connection enables precise positioning of the hinge part on the body. During the assembly of the household appliance, the hinge can thus be pre-positioned on the body in a first assembly step in such a way that the positioning element and the counter-positioning element interact and form the form-fitting connection. After this first assembly step, the hinge is optimally positioned in relation to the body. In a subsequent, second assembly step, the hinge can be permanently attached to the body, for example by means of screw connections.

The additional, form-fitting connection according to the invention results in an improved alignment of the hinge and thus of the closure element relative to the body in a simple manner. In addition, simplified and, in particular, faster assembly is made possible. In particular, a door hinge change, often carried out by end customers, in which the hinge or hinges are dismantled and reassembled at an opposite point on the body, is noticeably simplified and leads to a qualitatively better result.

The positive connection is formed separately and independently of a possible screw connection between the hinge and the body.

Embodiments of the present invention are specified in the subclaims.

In principle, an improvement in the alignment of the closure element with respect to the body and a simplification of the assembly can already be achieved if the positive connection acts in only one direction, which lies in a plane (or a plane parallel to it) that includes the contact surface. According to one embodiment, however, it is provided that the form-fitting connection acts in two directions lying perpendicular to one another and lying in a plane comprising the contact surface (or a plane parallel to it). In this way, the hinge is completely fixed within the plane by the form-fitting connection.

According to one embodiment it is provided that the positioning element is arranged adjacent to the contact surface. When looking at the contact surface at right angles, the positioning element is therefore outside the contact surface. Such an embodiment has the advantage that the area of the contact surface can remain unchanged compared to a conventional household appliance. That surface of the hinge which contacts the contact surface, namely the device contact surface, can thus also remain unchanged compared to a conventional hinge. In this case, for example, projections on the body directly adjoining the contact surface can be considered as positioning element. The projections can, for example, be cup-shaped or rib-shaped. In this case, for example, marginal edges of the hinge part on the carcass side come into consideration as the counter-positioning element. If the carcass-side hinge part has two mutually perpendicular edge edges (for example vertical and horizontal), it can in particular be provided that at least one positioning element contacts a first edge edge, while a second positioning element, which is formed separately from the first positioning element, contacts a second edge edge , which is perpendicular to the first edge. It is also conceivable that a single positioning element encompasses two edge edges that are perpendicular to one another at a corner area.

According to one embodiment it is provided that the positioning element is arranged within the contact surface. With a perpendicular view of the contact surface, the positioning element is therefore located completely within the boundaries of the contact surface. This creates a compact structure which, in particular, does not produce any effects of the proposed form-fitting connection on areas of the body outside the contact surface. The creation of additional gaps between the hinge part and a positioning element arranged laterally next to it can also be avoided. The risk of areas that are difficult to clean is thus minimized.

In principle, it is conceivable that the positioning element is configured separately from a component of the body which forms the contact surface. This is particularly advantageous if the positioning element is to be provided only for certain household appliances or in certain manufacturing systems or, for example, as an additional element when changing the door hinge. The positioning element can, for example, be inserted into an existing opening in the body or fastened therein. An improved positioning of the positioning element with respect to the flat contact surface can, however, be achieved if, according to one embodiment, it is provided that the positioning element is formed in one piece on a component of the body which forms the contact surface. In this way, the subsequent positioning of the closure element can be further improved. The component of the body can in particular be a cross member which extends from a left side to a right side of the body, for example in the case of a standing refrigeration device. For example, the cross member can be an upper end strip, a middle one Form an end strip or a lower end strip. The component of the body can comprise plastic and / or metal, in particular the component can be formed by a metal sheet. In this case, the positioning element can be formed or shaped by an embossing process. This has the advantage that the formation and thus the positioning of the positioning element itself can take place in a relatively late manufacturing step of the component. The position of the positioning element within the component can thus be determined very precisely.

According to one embodiment it is provided that the positioning element is arranged or positioned offset in the direction of the body with respect to the direction running perpendicular to the contact surface. The positioning element is thus designed, for example, as a recess or depression or depression or indentation or step. In this way, the positioning element does not protrude from the flat contact surface.

In particular, during the manufacture of the household appliance, the positioning element thus does not form a disruptive contour, so that the body of the household appliance can be transported lying on a front side that encompasses the contact surface, for example.

In this embodiment it can be provided in particular that the body-side hinge part has a counter-positioning element which engages in the positioning element. The counter-positioning element can be designed, for example, as a projection or tab or bracket or as a protruding edge. If the positioning element has a base, for example completely or at least substantially parallel to the contact surface, it can be provided that the counter-positioning element contacts the base. In principle, however, such contact is not necessary. However, it is preferably provided that the counter-positioning element makes contact with the lateral boundary walls of the positioning element extending in the direction of the body and thereby forms the form-fitting connection.

According to one embodiment it is provided that the positioning element is formed by a rotationally symmetrical trough. Such a shape can in particular be manufactured precisely, yet simply and inexpensively, by cold forming (for example embossing) a corresponding metallic component.

In principle, it is conceivable that the positioning element extending in the direction of the body is designed to be closed in accordance with, for example, a blind hole. In this way, there are no special requirements for tightness. Insulation material located behind the contact surface cannot escape through the positioning element. Alternatively, however, it is provided according to one embodiment that the positioning element and the counter-positioning element have aligned openings through which a screw is guided. According to this embodiment, the positive connection is thus arranged in the area of a conventional screw connection. In particular, it can be provided that the positioning element and / or the counter-positioning element are designed to be rotationally symmetrical. In particular, at least one of the openings or both openings can be arranged centrally in the positioning element and / or the counter-positioning element when the contact surface is viewed perpendicularly. It was found that such a position of the positioning element or the counter-positioning element can additionally increase the strength that can be achieved by the screw connection. The local rigidity of the component of the body that provides the contact surface and of the body-side hinge part is increased by the positioning element or counter-positioning element protruding with respect to the flat contact surface.

According to one embodiment it is provided that the body-side hinge part, at least in the area of the counter-positioning element, has a constant wall thickness.

According to one embodiment it is provided that the counter-positioning element forms a recess on a side facing away from the contact surface, the depth of which essentially corresponds to the height of a screw head of the screw. In this way, the additional advantage can be achieved that the screw head can be received completely or at least almost completely in this recess of the hinge part on the body side. This enables the use of screws with larger screw heads without the need to change the internal structure of the hinge due to a larger space requirement for the screw. In particular, according to this embodiment, the use of a flat head screw is conceivable. Compared to the countersunk head screws commonly used, the advantage can be achieved that higher screwing forces can be transmitted. In this context, “essentially” is to be understood as meaning that a protrusion of the screw head with respect to a surface of the first hinge part enclosing the recess is between 0.5 mm and 3 mm, or between 1 mm or 2 mm.

According to one embodiment, it is provided that the counter-positioning element forms a recess on a side facing away from the contact surface, which recess is an annular surface surrounding the opening of the counter-positioning element has, on which circular ring surface an underside of a screw head of the screw rests. This embodiment also enables the transmission of higher screwing forces between the body-side hinge part and the body.

According to one embodiment it is provided that the positioning element is arranged or positioned offset against the direction of the body with respect to the direction running perpendicular to the contact surface. The positioning element thus protrudes from the body, in particular from the contact surface. The positioning element can be formed, for example, by a projection or a bulge or a web or a tab. In this embodiment, the positioning element can form the interlocking connection in particular with one, two, three or more edge edges of the hinge part on the body side. In this case, the positioning element encompasses at least sections of one, two or more of the edge edges of the hinge part on the carcass. In this case, these marginal edges form the counter-positioning element or the counter-positioning elements. According to one embodiment, it is alternatively or additionally provided that the body-side hinge part has a counter-positioning element which, at least in sections, encompasses the positioning element. It can be provided in particular that the counter-positioning element is formed by an opening that is closed or open at the edge.

The closure element can be formed by a door, in particular with a vertically oriented pivot axis, or by a flap, in particular with a horizontally oriented pivot axis.

The object on which the invention is based is further achieved by a hinge for fastening a closure element of a household appliance to a body of a household appliance, the hinge comprising at least one hinge part designed for fastening to the body, which hinge part has a flat device contact surface, it being provided that on the hinge part is formed with at least one opposing positioning element protruding relative to the device contact surface with respect to a direction running perpendicular to the device contact surface. The counter-positioning element can be positioned within the device contact surface in particular when looking at the device contact surface at a right angle. The hinge can in particular have two, three or more counter-positioning means.

According to the previously described embodiments of the household appliance according to the invention, the counter-positioning element can form a positive connection with a corresponding positioning element on a body of a household appliance. The hinge according to the invention thus enables it to be fastened to a household appliance and, in the process, to provide precise positioning with respect to a body of the household appliance. In particular, the hinge according to the invention can be positioned during assembly in a first assembly step by means of the counter-positioning element before the hinge is finally fastened to the body, for example by means of a screw connection, in a subsequent, second assembly step.

The aforementioned features and properties of the hinge, which were disclosed in relation to the description of the household appliance according to the invention, can equally be transferred to the hinge according to the invention.

Identical or functionally identical elements are given the same reference symbols below.

In 1 is a household appliance 1 in the form of a household refrigerator, namely a fridge-freezer combination, which is designed for storing and preserving food. X denotes a width direction, Y a depth direction, and Z a height direction. The refrigeration device 1 in this example has two locking elements 2 ' , 3 ' in the form of doors 2 , 3 on which are used to close storage rooms. The upper door 2 is shown in an open state, so that an upper storage room 4th is accessible while the lower door 3 is shown in a closed state.

One body 5 of the refrigerator 1 has an outer wall 6th as well as an inner wall 7th on. While the outside wall 6th the outer boundary of the body 5 forms, limits the inner wall 7th the storage rooms, ie for example the upper storage room 4th . The inner wall 7th consists of plastic, in particular the inner wall is made by thermoforming.

The outside wall 5 comprises a left side wall as, in particular separately designed, wall elements 8th , a right side wall 9 , a top wall 10 , a bottom wall 11 and a rear wall (not shown) and a machine room wall (not shown). Both side walls 8th , 9 are made of sheet metal.

The body 5 furthermore has three cross members running essentially completely between the two side walls 8, 9 12th , 13th , 14th on. Depending on their position along the vertical direction Z, these form an upper end strip (cross member 12th ), a middle front ledge (cross member 13th ) as well as a lower front ledge (cross member 14th ). The cross members 12th , 13th , 14th serve on the one hand to the stability of the body 5 to increase. On the other hand, the cross members form 12th , 13th , 14th Contact surfaces for horizontal sections of seals 15th which each in the doors 2 , 3 are arranged. The cross members 12th , 13th , 14th consist of sheet metal and are one hand with the side walls 8th , 9 and on the other hand with the inner wall 7th forming inner container of the respective storage rooms connected.

Both doors 2 , 3 are each attached to the body by means of two hinges 5 hinged. So shows the upper door 2 a top hinge 16 as well as a lower hinge 17th as does the lower door 3 a top hinge 18th and a lower hinge 19th on. The upper and lower hinges of a door each allow the corresponding door to pivot about a common pivot axis. In the case of a multi-joint hinge, this enables a translational and rotational movement of the door.

The outside wall 6th and the inner wall 7th are connected to one another and delimit a cavity filled with insulation material. The cross members 12th , 13th , 14th also serve to limit the cavity, ie they are in contact with the insulation material on the back (in this case polyurethane foam).

In the storage room 4th are shelves 20th and a drawer 21 and at the door 2 Door racks 22nd arranged, each of which is used to receive the stored goods to be cooled.

2 shows a section of the cross member serving as the upper front strip 12th in the area of the attachment of the hinge 16 . For illustration purposes only the cross member is 12th shown.

The crossbar 12th has two openings spaced from one another and arranged on a horizontal plane (ie the same height position along the height direction Z) 23 on.

These are used to attach the hinge 16 on the crossbar 12th and thus on the body 5 . The openings are used in particular 23 for fastening the hinge 16 by means of a screw connection comprising two screws. The crossbar 12th exhibits further breakthroughs 24 as well as blind holes 25th which could be used to attach an alternative type of hinge or cover, and to attach the hinge 16 are not needed.

The crossbar 12th has a flat contact surface 26th on whose limitation 27 in 2 is shown in dashed lines. The contact surface 26th lies in a plane spanned by the width direction X and the height direction Z. The contact surface 26th is used to attach the hinge 16 and thus enables the hinge to be positioned 16 in depth direction Y.

The crossbar 12th furthermore has two positioning elements 28 on. The two positioning elements 28 are formed separately from one another and are also on a common horizontal plane. Both positioning elements 28 are designed identically. The positioning elements 28 are along a perpendicular to the contact surface 26th extending direction, namely the depth direction Y, with respect to the contact surface 26th staggered. In particular, the positioning elements 28 with respect to this direction (depth direction Y) in the direction of the body 5 staggered.

The positioning elements 28 are through rotationally symmetrical troughs 29 educated. The hollows 29 each have a trough bottom 30th as well as the hollow bottom 30th with the contact surface 26th connecting side walls 31 on. The hollow bottom 30th is just trained. In particular, the trough bottom runs 30th in a plane spanned by the width direction X and the height direction Z. The side walls 31 are arranged inclined with respect to the depth direction Y, so that the trough has a frustoconical shape 29 is present. The sloping side walls 31 enable simplified production.

The positioning elements 28 are each integral with the cross member 12th educated. In particular, the positioning elements 28 by embossing the cross member 12th generated so that the cross member 12th in the area of the positioning elements 28 has an essentially constant wall thickness and there is a local increase in rigidity.

The positioning elements 28 are both essentially completely within the contact surface 26th arranged.

3 shows a to 2 comparable representation of the upper right end section of the cross member 12th , this time with a hinge attached 16 .

The hinge 16 almost a hinge part on the body 32 , which is formed by a substantially flat section with constant wall thickness. The hinge part on the carcase is different 32 a transition part closes 33 at. On the transition part 33 in turn is a door-side hinge part 34 with a bearing pin formed on it 35 arranged. The hinge 16 is formed in one piece in this embodiment and formed by a stamped and bent component.

The carcase-side hinge part 32 has one of the contact surfaces 26th facing device contact surface 36 (please refer 4th ) on. Between the contact surface 26th and the device contact surface 36 there is extensive contact. The device contact area 36 is thus also in the contact surface 26th just trained.

The hinge 16 , especially the hinge part on the body side 32 , has two opposing positioning elements 37 on. The two opposing positioning elements 37 are designed identically and are on a common height level. The counter-positioning elements 37 are arranged at a distance from one another in the width direction X. The counter-positioning elements 37 are each through cup-shaped bulges on the body-side hinge part 32 integrally formed on this and engage in the trough-shaped positioning elements 28 in depth direction Y.

The counter-positioning elements 37 each have breakthroughs 38 (please refer 4th ) that are aligned with the breakthroughs 23 within the contact area 26th are trained. Screws 39 penetrate the breakthroughs 23 , 38 and attach the hinge 16 permanently by means of a non-positive connection on the cross member 12th and thus on the body 5 .

In 4th is a look at the in 3 The sectional plane shown in dashed lines along the viewing direction A is shown.

In depth direction Y behind an end face 40 the cross member 12th there is a backing part 41 . The deposit 41 has two breakthroughs 42 with one thread each 43 to securely screw the hinge together 16 on the crossbar 12th to enable. The deposit 41 shows 2 to the contour of the positioning elements 28 adjusted setbacks 44 on.

As can be seen, each screw head has 45 a height 46 that is less than a depth 47 the counter-positioning elements 37 . the screw heads 45 are thus one of the device contact surfaces 36 opposite surface 48 of the carcase-side hinge part 32 sunk arranged. By the counter-positioning elements 37 thus there is sufficient space for screws that are larger than conventional screws 39 created. In the present case, it concerns flat head screws, which with a flat circular ring surface as the underside of the screw head 45 the level trough floor 30th to contact.

The counter-positioning elements 37 point starting from the flat section of the body-side hinge part 32 side walls 49 as well as an adjoining floor 50 on. While the ground 50 is flat, are the side walls 49 arranged inclined with respect to the depth direction Y. In particular, the side walls 49 substantially the same slope as the side walls 31 of the positioning element 28 on.

When assembling the hinge 16 this is initially essentially in the depth direction Y to the cross member 12th pushed. Slight deviations in the position of the hinge 16 in the width direction X or height direction Z during this process with respect to the target position, by inserting the counter-positioning elements 37 in the positioning elements 28 corrected. Because of the sloping side walls 31 or. 49 the counter-positioning elements are centered 37 in the positioning elements 27 so that the target position of the hinge 16 is reliably achieved in a simple manner. In one the screws are now the next assembly step 39 screwed in to the hinge 16 finally at the cross beam 12th to fix.

In the then achieved, fastened state of the hinge 16 (in 3 and 4th shown) contacts the device contact surface 36 the contact surface over the entire surface 26th . At the same time, facing surfaces of the side walls make contact 31 and 49 . Between the hollow bottom 30th and these facing surfaces of the floors 50 however, there is a gap 51 before to overdetermine the positioning of the hinge 16 to exclude.

The hinge 16 extends to the counter-positioning elements 37 completely in front of the contact surface 26th .

In the 5 to 7th a second embodiment is shown.

The 5 and 6th show an upper, right-hand section of the household appliance 1 , with in 5 the hinge 55 as well as the door 2 are not shown.

In contrast to the first embodiment, the body 5 , namely the upper cross member 12th , two positioning elements 52 on that with respect to a perpendicular to the contact surface 26th running direction - namely the depth direction Y - opposite to the direction of the body 5 are arranged offset. The positioning elements 52 thus protrude from the body, in particular from the cross member 12th , and in particular from the contact surface 26th , out.

The two positioning elements 52 are through cup-like projections 56 the cross member 12th formed in one piece on this. The positioning elements 42 have different diameters, but are arranged at the same height.

The positioning elements 52 engage in counter-positioning elements 53a , 53b of the hinge 55 a. The counter-positioning elements 53a , 53b are in the hinge part on the cabinet side 32 educated. The counter-positioning elements 53a , 53b grip around the positioning elements 52 at least partially extensively. That in the 5 and 6th Counter-positioning element shown on the left 53a is through an open-edged breakthrough 54a formed, while the counter-positioning element shown on the right 53b through an opening closed at the edge 54b is formed. By the hinge 55 it is a multi-joint hinge according to the prior art. Both breakthroughs 54a , 54b are on this hinge 55 already available and the hinge is used for this 55 even with only partially loosened screws 39 from the body 5 to dismantle by moving it in width direction X in relation to the body This embodiment makes these already existing breakthroughs 54a , 54b thus to use as counter-positioning elements according to the invention 53a , 53b in connection with the corresponding positioning elements 52 to form the positive connection.

As in 7th can be seen, are the interacting positioning elements 52 Counter-positioning elements 53a , 53b on the screws 39 and thus spaced and separated from the screw connections.

8th shows a section of the upper cross member 12th out 1 according to a third embodiment.

As in the second embodiment, the cross member 12th as a positioning element 52 on the one hand a cup-like projection 56 on. In a modification of the second exemplary embodiment, the end strip 12th as a further positioning element 57 a tab 58 on. The tab 58 is in one piece on the cross beam 12th formed and protrudes against the depth direction Y, in this embodiment perpendicular, from the contact surface 26th out.
