Description

Domestic appliance with a hinge and hinge for a domestic appliance

Technical Field

The invention relates to a household appliance, in particular a household refrigerator, having a body and a closure element which closes a storage space in the body and is articulated to the body by means of at least one hinge (Scharnier), wherein the hinge comprises a body-side hinge part which is fastened to a flat contact surface on the body.

Background

Such a domestic appliance may be a refrigerator, for example a refrigerator, or a freezer or a combination of freezer and refrigerator.

The closure element (e.g., door) is typically hinged (i.e., stopped) on the body by two hinges spaced from each other along the pivot axis of the closure element. The closure element can be pivoted about a pivot axis in order to gain access to the storage space or to achieve a closed storage space. In the closed state of the closure element, the seal, which is usually arranged on the closure element, seals the storage space. For built-in household appliances

A furniture plate is additionally arranged on the outer side of the closing element. On the one hand, a precise orientation of the closure element in the closed state relative to the body is required for achieving an optimal sealing in the closed state of the closure element. On the other hand, particularly for built-in domestic appliances, a precise orientation of the closure element relative to the body is required for achieving a uniform gap between the closure element (particularly in the closed state) and the adjacent furniture.

In order to achieve a precise orientation of the closure element relative to the body and at the same time to transmit the necessary forces, these hinges typically have a flat rest surface for resting on the body and are typically fixed to the body by means of two bolts/screws (Schrauben).

Disclosure of Invention

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

This object is achieved according to the independent claims. In a domestic appliance, in particular a domestic refrigerator, having a body and a closure element which closes a storage space in the body and is articulated to the body by means of at least one hinge, wherein the hinge comprises a body-side hinge part which is fastened to a flat contact surface on the body, it is provided according to the invention that the body has a positioning element which is arranged offset with respect to the contact surface in a direction extending perpendicular to the contact surface and forms a form-fitting connection with the body-side hinge part.

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

The hinge can be constructed in one piece or in several pieces. In any case, the hinge includes a hinge portion (i.e., a hinge portion on the body side) that is fixed 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 fixed to a flat contact surface of the body. The contact surface of the body here in particular forms the surface: said surface is in direct contact with the hinge, in particular the hinge part on the body side.

The invention is based on the recognition that: the conventional fastening of the hinge (for example by means of a screw connection) to the flat contact surface nevertheless provides the necessary strength for the connection. However, in order to achieve the necessary accuracy in the orientation of the closure element relative to the body, a precise arrangement of the helical bore in the bearing face on the one hand and in the hinge portion on the other hand is necessary. Furthermore, a precise orientation of the hinge with respect to the body is necessary when mounting the hinge.

Instead of the hinge being fixed solely by the flat contact surface of the body, the invention proposes that a form-locking connection be additionally provided. For this purpose, a positioning element is arranged on the body, which positioning element forms a form-locking connection with the hinge part on the body side (in particular a counter-positioning element of the hinge part on the body side). The positioning elements are arranged offset with respect to the plane comprising the rest face (and thus with reference to the rest face) in a direction extending perpendicular to the rest face.

This additional form-locking connection enables a precise positioning of the hinge part on the body. In a first installation step, the hinge can thus be pre-positioned on the body in such a way that the positioning element and the counter-positioning element can interact and form a form-fitting connection when the household appliance is installed. After this first mounting step, the hinge is optimally positioned with respect to the body. In a subsequent second mounting step, the hinge can be permanently fixed to the body (for example by means of a screw connection).

By means of the additional form-locking connection according to the invention, an improved orientation of the hinge and thus of the closure element relative to the body is achieved in a simple manner. Furthermore, a simplified and in particular faster installation is achieved. In particular, the door stop change (taranschlagswechsel) usually performed by the end customer, in which one or more hinges are detached and mounted again at opposite points on the body, is also significantly simplified and leads to better results in terms of quality.

This form-locking connection is formed separately and independently of a possible screw connection between the hinge and the body.

Alternative embodiments of the invention are given in the dependent claims.

Basically, an improved orientation of the closure element relative to the body and a simplified installation can already be achieved if such a form-fitting connection acts in only one direction in a plane comprising the rest face (or a plane parallel thereto). However, according to one embodiment, it is provided that the form-locking connection acts in two directions lying in a plane (or a plane parallel thereto) including the rest face and perpendicular to one another. In this way, the hinge is completely fixed within the plane by means of a form-locking connection.

According to one specific embodiment, it is provided that the positioning element is arranged adjacent to the contact surface (benachbart). When the contact surface is viewed perpendicularly, the positioning element is thus located outside the contact surface. Such embodiments have the advantage that: the area of the rest face can remain unchanged with respect to a conventional household appliance. Thus, the surface of the hinge that comes into contact with the rest surface (i.e. the appliance rest surface) may also remain unchanged with respect to a conventional hinge. In this case, it is conceivable, for example, for a projection on the body which engages directly on the contact surface to be a positioning element. These projections may be, for example, can-shaped or rib-shaped. In this case, the edge (Randkanten) of the hinge part on the body side is considered as a counter-positioning element. If the hinge part on the body side has two edge edges (for example vertical and horizontal) which are perpendicular to one another, it can be provided in particular that at least one positioning element comes into contact with a first edge, while a second positioning element, which is designed separately from the first positioning element, comes into contact with a second edge which is perpendicular to the first edge. Likewise, it is conceivable for a single positioning element to enclose two edge edges which are perpendicular to one another in the corner region.

According to one embodiment, it is provided that the positioning element is arranged within the contact surface. When viewed perpendicularly on the rest face, the positioning element is thus located completely within the boundaries of the rest face. This results in a compact design which, in particular, does not have the effect of the proposed form-locking connection on the region of the body outside the contact surface. The occurrence of additional play between the hinge part and the positioning element arranged laterally next thereto can also be avoided. Thereby, the risk of hard-to-clean parts is minimized.

It is basically conceivable for the positioning element to be formed separately from the component of the body which forms the contact surface. This is particularly advantageous if the positioning element is to be provided as an additional element only in a specific household appliance or in a specific production facility or, for example, in the event of a door stop change. The positioning element can, for example, be inserted into an already existing opening of the body (or be fixed in this opening). However, according to one embodiment, it is provided that, when the positioning element is integrally formed on the component of the body which forms the contact surface, an improved positioning of the positioning element relative to the flat contact surface can be achieved. In this way, the subsequent positioning of the closure element can be improved again. The components of the body can be, in particular, cross bars (quaterperses), which extend from the left to the right of the body, for example in upright refrigeration appliances. For example, the cross-bar may constitute an upper end-bar (Stirleist), a middle end-bar or a lower end-bar. The components of the body may comprise plastic and/or metal, and in particular, the components may be constructed from sheet metal. In this case, the positioning element may be constructed or shaped by a pressing process. This has the advantage that: the configuration of the positioning element itself and thus its positioning can take place in a relatively late production step of the component. Thus, the position of the positioning element inside the component can be determined very accurately.

According to one embodiment, it is provided that the positioning elements are arranged or positioned offset in a direction extending perpendicular to the contact surface in the direction of the body. The positioning element is thus configured, for example, as a recess or depression or cavity or indentation or step. In this way, the positioning element does not project with respect to the flat rest face. Thus, in particular during the production of the domestic appliance, the positioning element does not form an interfering contour, so that the body of the domestic appliance can be transported flat, for example with the front side comprising the resting face.

In this embodiment, it can be provided in particular that the hinge part on the body side has a corresponding positioning element which engages into the positioning element. The counter-positioning element can be embodied, for example, as a projection or a lug (lasch), a bow (B ü gel) or as a projecting edge. If the positioning element has a base (for example, oriented completely parallel or at least substantially parallel to the contact surface), it can be provided that the counter-positioning element comes into contact with this base. Basically, however, such contact is not necessary. However, it is preferably provided that the respective positioning element comes into contact with a lateral limiting wall of the positioning element extending in the direction of the body and forms a form-locking connection in this case.

According to one embodiment, it is provided that the positioning element is formed by a rotationally symmetrical recess. Such shapes can be produced in particular precisely and yet simply and inexpensively by cold-forming (for example pressing) the respective metal component.

It is basically conceivable for the positioning element extending in the direction of the body to be of a closed design, for example as a blind hole. In this way, there is no particular requirement for the sealing properties. The insulating material located behind the resting surface does not pass through the positioning element. Alternatively, however, it is provided according to one embodiment that the positioning element and the counter-positioning element have aligned passages through which the screws are guided. Thus, according to this embodiment, the form-locking connection is arranged in the region of a conventional screw connection. In particular, it can be provided that the positioning element and/or the counter-positioning element are rotationally symmetrical. In particular, at least one or both of these openings can be arranged centrally in the positioning element and/or the corresponding positioning element, when viewed perpendicularly on the contact surface. It has been found that such a position of the positioning element (or of the counter-positioning element) can additionally increase the strength that can be achieved by a screw connection. The local rigidity of the body and of that component of the hinge part on the side of the body which provides the rest face is increased by the positioning element (or corresponding positioning element) projecting relative to the flat rest face.

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

According to one embodiment, it is provided that the corresponding positioning element forms a depression on the side facing away from the contact surface, the depth of which corresponds substantially to the height of the screw head of the screw. In this way, additional advantages can be achieved: the screw head can be completely or at least almost completely received in this recess of the body-side hinge part. This enables the use of screws with larger screw heads without having to change the internal construction of the hinge due to the larger space requirement for the screws. In particular, according to this embodiment, the use of flat-head screws is envisaged. Flat head screws can achieve such advantages over the commonly used countersunk head screws: a higher screw force can be transmitted. Here, "substantially" is understood to mean: the protrusion of the screw head with respect to that surface of the first hinge part which encloses the recess is between 0.5mm and 3mm or between 1mm or 2 mm.

According to one embodiment, it is provided that the counter-positioning element forms a recess on the side facing away from the contact surface, which recess has a circular ring surrounding the passage opening of the counter-positioning element, on which circular ring the underside of the screw head of the screw contacts. This embodiment also enables a high transmission of the screw force between the hinge portion on the body side and the body.

According to one embodiment, it is provided that the positioning elements are arranged (or positioned) offset with respect to a direction running perpendicular to the contact surface, counter to the direction of the body. The positioning element thus protrudes from the body (in particular from the rest face). The positioning element can be formed, for example, by a projection or a bulge or a web (Steg) or a web. In this embodiment, the positioning element can be connected in a form-fitting manner to one, two, three or more edge edges in the hinge section on the body side. In this case, the positioning element surrounds one, two or more of the edge edges of the hinge part acting on the body side at least in sections. In this case, these edge edges form one or more corresponding positioning elements. According to one embodiment, it is alternatively or additionally provided that the hinge part on the body side has a counter-positioning element which surrounds the positioning element at least in sections. In this case, it can be provided, in particular, that the counter-positioning element is formed by a perforation which is closed at the edge or open at the edge.

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

The object on which the invention is based is furthermore achieved by a hinge for fastening a closing element of a household appliance to a body of the household appliance, comprising at least one hinge part which is designed for fastening to the body and which has a flat appliance contact surface, wherein it is provided that at least one corresponding positioning element which projects relative to the appliance contact surface with reference to a direction which runs perpendicular to the appliance contact surface is designed on the hinge part. In particular, the counter-positioning element can be positioned within the appliance contact surface when viewed in the vertical viewing direction. The hinge may in particular have two, three or more corresponding positioning means.

In accordance with the previously described embodiment of the domestic appliance according to the invention, the corresponding positioning element can form a form-fitting connection with a corresponding positioning element on the body of the domestic appliance. The hinge according to the invention can thus be fixed to a domestic refrigeration appliance and can in this case be positioned precisely relative to the body of the domestic appliance. In particular, during mounting, the hinge according to the invention can be positioned by means of corresponding positioning elements in a first mounting step, before the final fixing of the hinge (for example by means of a screw connection) on the body in a subsequent second mounting step.

The previously mentioned features and characteristics of the hinge disclosed in connection with the description of the household appliance according to the invention can equally be transferred to the hinge according to the invention.

By the statements "upper", "lower", "front", "rear", "horizontal", "depth direction", "width direction", "height direction", etc., the positions and orientations are explained which result when the household appliance is used and arranged as intended and when an observer stands in front of the household appliance and looks at the household appliance.

Detailed Description

Fig. 1 shows a household appliance 1 in the form of a household refrigerator (i.e., a refrigerator-freezer combination), which household appliance 1 is designed for storing and preserving food. X denotes a width direction, Y denotes a depth direction and Z denotes a height direction. In this example, the household appliance 1 has two closing elements 2 ', 3' in the form of doors 2, 3, which are used to close the storage space. The upper door 2 is shown in an open state so that the storage space 4 above is accessible, while the lower door 3 is shown in a closed state.

The body 5 of the refrigerator 1 has an outer wall 6 and an inner wall 7. The outer wall 6 forms the outer boundary of the body 5, while the inner wall 7 delimits the storage space (that is to say, for example, the upper storage space 4). The inner wall 7 is made of plastic, in particular by thermoforming.

The outer wall 5 comprises a left side wall 8, a right side wall 9, a top wall 10, a bottom wall 11, as well as a rear wall, not shown, and a machine space wall, not shown, as wall elements (in particular constructed separately). The two

side walls

8, 9 are made of sheet metal.

The body 5 furthermore has three

transverse bars

12, 13, 14 which extend substantially completely between the two

side walls

8, 9. These

crossbars

12, 13, 14 form, depending on their position in the height direction Z, an upper end bar (crossbar 12), a middle end bar (crossbar 13) and a lower end bar (crossbar 14). On the one hand, these

crossbars

12, 13, 14 serve to increase the stability of the body 5. On the other hand, the

crossbars

12, 13, 14 form contact surfaces for the horizontal sections of the seals 15, which seals 15 are arranged in the doors 2, 3, respectively. The

transverse bars

12, 13, 14 are made of sheet metal and are connected on the one hand to the

side walls

8, 9 and on the other hand to the inner containers of the storage spaces which form the inner wall 7.

The two doors 2, 3 are each hinged to the body 5 by means of two hinges. The upper door 2 has an upper hinge 16 and a lower hinge 17, and similarly, the lower door 3 has an upper hinge 18 and a lower hinge 19. The upper and lower hinges of one door are each capable of effecting pivoting of the respective door about a common pivot axis. In the case of a multiple hinge (Mehrgelenkscharnier), the multiple hinge enables both translational and rotational movement of the door.

The outer wall 6 and the inner wall 7 are connected to each other and delimit a cavity filled with an insulating material. Here, the

rails

12, 13, 14 are also used to delimit the cavity, i.e. they are in contact with an insulating material (in this case polyurethane foam) on the rear side.

In the storage space 4, a shelf 20 and a drawer 21 are arranged, and on the door 2, door shelves 22 are arranged, which door shelves 22 are each used for receiving refrigerated goods to be refrigerated.

Fig. 2 shows a section of the transverse bar 12 used as an upper end bar in the fastening region of the hinge 16. For purposes of illustration, only crossbar 12 is shown.

The crossbar 12 has two through openings 23 spaced apart from one another and arranged in a horizontal plane (that is to say at the same height position in the height direction Z). These through openings 23 are used to fix the hinge 16 to the crossbar 12 and therefore to the body 5. In particular, these openings 23 are used to fix the hinge 16 by means of a screw connection (comprising two screws). The transverse bar 12 has further passages 24 and blind holes 25, which further passages 24 and blind holes 25 can be used for fastening alternative hinge types or covers, but are not required for fastening the hinge 16.

The crossbar 12 has a flat rest face 26, the boundary 27 of which rest face 26 is shown in dashed lines in fig. 2. The seating surface 26 is located in a plane spanned by the width direction X and the height direction Z. The abutment surface 26 serves for abutment of the hinge 16 and thus for positioning of the hinge 16 in the depth direction Y.

Furthermore, the crossbar 12 has two positioning elements 28. The two positioning elements 28 are formed separately from one another and are also located on a common horizontal plane. The two positioning elements 28 are identically constructed. These positioning elements 28 are arranged offset with respect to the rest face 26 in a direction extending perpendicular to the rest face 26 (i.e. the depth direction Y). In particular, the positioning elements 28 are arranged in a staggered manner with reference to this direction (depth direction Y) towards the body 5.

These positioning elements 28 are formed by rotationally symmetrical cavities 29. These cavities 29 each have a cavity bottom 30 and a side wall 31 connecting the cavity bottom 30 to the rest surface 26. The cavity bottom 30 is configured flat. In particular, the pocket bottom 30 extends in a plane spanned by the width direction X and the height direction Z. These side walls 31 are arranged obliquely with reference to the depth direction Y so that there is a truncated cone-shaped pattern of cavities 29. These sloping side walls 31 enable a simplified production.

These positioning elements 28 are each constructed integrally with the transverse rod 12. In particular, these positioning elements 28 are produced by pressing the transverse rod 12, so that the transverse rod 12 has a substantially constant wall thickness in the region of the positioning elements 28 and there is a local increase in rigidity.

The two positioning elements 28 are arranged substantially completely within the rest face 26.

Fig. 3 shows a view comparable to fig. 2 of the upper right end section of the transverse bar 12, which here has a hinge 16 fastened to the transverse bar.

The hinge 16 comprises a hinge part 32 on the body side, which hinge part 32 is formed by a substantially flat section with a constant wall thickness. The transition portion 33 engages with this hinge portion 32 on the body side. In turn, a door-side hinge part 34 is arranged on the transition part 33, which door-side hinge part 34 has a journal 35 formed thereon. In this embodiment, the hinge 16 is constructed in one piece and consists of a stamped and bent member (Stanz-Biege-Bauteil).

The hinge part 32 on the body side has a device rest face 36 facing the rest face 26 (see fig. 4). There is a surface contact between the rest surface 26 and the appliance rest surface 36. Thus, the tool support surface 36 is also configured to be flat, as is the support surface 26.

The hinge 16, in particular the hinge part 32 on the body side, has two corresponding positioning elements 37. The two counter-positioning elements 37 are identically designed and lie on a common height plane. These corresponding positioning elements 37 are arranged spaced apart from each other in the width direction X. These counter-positioning elements 37 are each formed integrally on the body-side hinge part 32 by a bowl-shaped bulge of the body-side hinge part 32 and engage in the depth direction Y in the cavity-shaped positioning element 28.

The counter-positioning elements 37 each have a passage 38 (see fig. 4), which passages 38 are formed in alignment with the passages 23 within the contact surface 26. The screws 39 pass through these

openings

23, 38 and permanently fix the hinge 16 to the crossbar 12 and thus to the body 5 by means of a force-fitting connection.

Fig. 4 shows a view of a sectional plane shown in fig. 3 with a dashed line, viewed along the viewing direction a.

The rear piece 41 is located behind the end face 40 of the crossbar 12 in the depth direction Y. The rear part 41 has two openings 42, each provided with a threaded feed 43, in order to achieve a secure fastening of the hinge 16 to the crossbar 12. The rear part 41 has two recesses 44 which match the contour of the positioning element 28.

As can be seen, each screw head 45 has a height 46, said height 46 being smaller than the depth 47 of the corresponding positioning element 37. Thus, the screw head 45 is arranged sunk with respect to the surface 48 of the body-side hinge part 32 opposite the tool rest face 36. Thus, sufficient receiving space for a larger screw 39 than conventional screws is obtained by the corresponding positioning element 37. In the present case, this relates to a flat-head screw which contacts the flat recess bottom 30 with a flat torus as the underside of the screw head 45.

The counter-positioning elements 37, proceeding from the flat section of the body-side hinge part 32, have side walls 49 and a base 50 adjoining them. The bottom 50 is of flat design, while the side walls 49 are arranged obliquely with respect to the depth direction Y. In particular, these side walls 49 have substantially the same inclination as the side walls 31 of the positioning element 28.

When mounting the hinge 16, the hinge 16 is first pushed substantially in the depth direction Y onto the crossbar 12. The slight deviations of the position of the hinge 16 in the width direction X (or height direction Z) in the process with reference to the nominal position are corrected by the introduction of the corresponding positioning element 37 into the positioning element 28. The corresponding positioning elements 37 are centered in the positioning elements 28 due to the

inclined side walls

31 and 49, so that the nominal position of the hinge 16 is reliably reached in a simple manner. In a further mounting step, screws 39 are screwed in order to finally fix the hinge 16 to the crossbar 12.

In the achieved, secured state of the hinge 16 (shown in fig. 3 and 4), the appliance rest face 36 is completely in contact with the rest face 26. At the same time, the surfaces of these

side walls

31 and 49 facing each other come into contact. However, a gap 51 exists between the cavity bottom 30 and the surface of the bottom 50 facing the cavity bottom 30 in order to preclude over-determination when the hinge 16 is positioned.

The hinge 16 extends completely in front of the rest face 26, except for the corresponding positioning element 37.

A second embodiment is shown in fig. 5 to 7.

Fig. 5 and 6 show the upper right section of the household appliance 1, wherein the hinge 55 and the door 2 are not shown in fig. 5 for illustration purposes.

Unlike the first exemplary embodiment, the body 5 (i.e., the upper crossbar 12) has two positioning elements 52, which positioning elements 52 are arranged in a staggered manner with reference to a direction extending perpendicular to the resting surface 26 (i.e., the depth direction Y) opposite to the direction of the body 5. Thus, the positioning elements 52 project from the body (in particular from the crossbar 12), and in particular from the resting face 26.

The two locating elements 52 are integrally constructed on the bowl-shaped projection 56 of the crossbar 12 from the bowl-shaped projection 56. The positioning elements 52 have different diameters here, but are arranged at the same height.

These positioning elements 52 are embedded in corresponding positioning elements 53a, 53b of the hinge 55. These corresponding positioning elements 53a, 53b are constructed in the body-side hinge part 32. The positioning elements 52 are surrounded at least in sections circumferentially by the corresponding positioning elements 53a, 53 b. The counter-positioning element 53a shown on the left in fig. 5 and 6 is formed by an open-edged passage 54a, while the counter-positioning element 53b shown on the right is formed by a closed-edged passage 54 b. The hinge 55 relates to a multi-coupling hinge according to the prior art. These two through-openings 54a, 54b are already present in such a hinge 55 and serve for detaching the hinge 55 from the body 5 even in the case of only partial loosening of the screw 39 in such a way that the hinge 55 can be moved in the width direction X relative to the body 5. This embodiment thus makes use of the two already existing openings 54a, 54b in order to form a form-locking connection as the corresponding positioning elements 53a, 53b according to the invention in combination with the respective positioning element 52.

As can be seen in fig. 7, the cooperating positioning elements 52 and the corresponding positioning elements 53a, 53b are next to the screw 39 and are thus spaced apart and separated from the screw connections.

Fig. 8 shows a section of the upper crossbar 12 from fig. 1 according to a third embodiment.

As in the second exemplary embodiment, the crossbar 12 as the positioning element 52 has, on the one hand, a bowl-shaped projection 56. In a modification of the second exemplary embodiment, the end strip 12 has a web 58 as a further positioning element 57. The webs 58 are integrally formed on the transverse bar 12 and project opposite the depth direction Y (in this embodiment perpendicularly) from the rest face 26.
