Definitions

  • HOUSEHOLD APPLIANCE WITH A SYMMETRIC BEARING ANGLE OF A HINGE FOR A DOOR, AND METHOD FOR MANUFACTURING A HOUSEHOLD APPLIANCE
  • One aspect of the invention relates to a household appliance with a housing. At least one receiving space for food is formed in the housing.
  • the household appliance has at least one hinge that is arranged on a front of the housing.
  • the household appliance also has a door that is arranged on the hinge. As a result, the door is pivotably arranged relative to the housing.
  • One aspect of the invention also relates to a method.
  • Household appliances are known, for example, as household refrigeration appliances. These typically have a housing with a door pivotally mounted thereon. A hinge is implemented to allow this pivoting. Hinges of this type have bearing brackets. In this context, there are also configurations in which these bearing brackets are arranged on the front of the door. For example, they are screwed to a front flange of the housing. Such a configuration is known, for example, from EP 1 679481 A2.
  • the bearing bracket there has an elongated, horizontal rail with which the bearing bracket is attached directly to the front of the housing. Furthermore, viewed in the width direction, this bearing bracket has a bearing pin arranged asymmetrically to this rail.
  • the door is mounted on this bearing bolt. With such a completely asymmetrical bearing bracket, the door can only be mounted in one direction.
  • a hinge device for a domestic refrigerator is known from DE 203 12 282 U1.
  • the hinge device has a bearing block which can be screwed onto a body of the household refrigeration appliance.
  • This bearing block has a vertically oriented plate with which the bearing block can be screwed to the body. Viewed in the width direction, this plate has two separate mounting openings which are formed at a distance from one another and through which the screws can be passed.
  • this bearing block has two separate bearings, which are formed side by side in the width direction.
  • a bearing bolt which is designed separately thereto, can be inserted and fastened into one of these bearings, in particular screwed into it.
  • On this bearing pin a bearing bush can then be rotatably attached, which in turn can be attached to the door.
  • the two bearings are arranged offset to the assembly openings.
  • This bearing bracket can also only be installed and used in a specific position of the housing.
  • One aspect of the invention relates to a household appliance with a housing. At least one receiving space for food is formed in the housing.
  • the household appliance also has at least one hinge. This hinge is arranged on a front of the housing.
  • the household appliance also has a door. This door is arranged on the hinge and is thereby pivotally arranged relative to the housing.
  • the hinge has a bearing bracket that is fastened to an end face of the front with at least one fastening element. The bearing angle is constructed symmetrically when the household appliance is viewed from the front.
  • a symmetrical structure means in particular that functionally essential features of the bearing bracket are arranged symmetrically to one another.
  • the symmetry is to be seen in particular in relation to a vertical axis of the bearing bracket.
  • the vertical axis extends in the vertical direction of the household appliance.
  • Functional features of the bearing bracket are in particular those that relate to a support function and/or holding function for attachments on the bearing bracket that are separate from the bearing bracket and/or those that have a function of connecting the bearing bracket to another component of the household appliance.
  • Such features are, for example, a bearing bolt or a bearing journal for a door and/or at least one hole through which a fastening element, in particular a screw, can be passed so that the bearing bracket can be attached to a component, in particular a housing, of the household appliance.
  • the bearing angle is symmetrical only with respect to these features. It is then only component-related symmetric.
  • the bearing angle can also be asymmetrical.
  • the bearing angle can also be symmetrical in this respect and is then completely symmetrical. It is then not only symmetrical in relation to the components.
  • the bearing bracket is designed for optional installation on a left-hand end face of the front in the width direction and when viewing the household appliance from the front, or on a right-hand end face of the front.
  • the door is thus arranged in the same position on the housing in the height direction of the household appliance and in the width direction of the household appliance in the closed state.
  • Such a symmetrical bearing bracket can thus be used both for right-hand and left-hand installation on an end face of the front of the housing.
  • This one bearing angle can thus be used both for household appliances in which the door can be rotated about a vertical axis of rotation on the left when viewed from the front.
  • this bearing angle can also be used in household appliances in which a door, when viewed from the front, is intended to be pivotable about a right-hand vertical axis of rotation.
  • the bearing angle is embodied symmetrically, viewed in the width direction.
  • the installation position of the bearing bracket on the left-hand end face and in particular in relation to a left-hand end of the housing can be formed with the same spacing as a corresponding right-hand shoring, in which this bearing bracket then has the same distance to a right-hand end of the housing.
  • the door is always arranged in the same height and width position on the housing, whether it is to be installed as a left-hand or right-hand door according to the invention.
  • receptacles on the front of the housing which are provided for receiving fastening elements, are formed at the same distance with regard to their respective adjacent, left-hand and right-hand ends or walls of the housing.
  • a distance measured in the width direction from a left-hand end of the housing is equal to the distance from fastening elements that are correspondingly formed on the right-hand side and that are arranged or formed adjacent to a right-hand edge of the housing are, is.
  • Such fastening element receptacles are also formed on the front of the housing symmetrically to a center of the front of the housing, such a bearing bracket that is symmetrical in this respect in the width direction can also result in a symmetrical installation position of the bearing bracket relative to this center of the housing or the center of the front of the housing .
  • the bearing bracket is embodied symmetrically with respect to an axis of symmetry oriented in the vertical direction of the household appliance.
  • the bearing bracket has a contact plate that rests directly on the face of the front.
  • the contact plate is completely in contact with this end face. This means that maximum support of these Contact plate results on the front side. This enables a particularly stable attachment of the bearing bracket.
  • the bearing bracket is arranged such that it projects forward from the end face.
  • the bearing bracket thus does not extend backwards over this face but only forwards.
  • the contact plate is therefore the component of the bearing bracket that is arranged furthest to the rear, viewed in the depth direction.
  • the bearing bracket has, in one embodiment, a support plate protruding forward at an angle from it. This support plate is designed to support a bearing bolt that extends in the vertical direction.
  • the bearing pin is also part of the bearing bracket.
  • the contact plate and this support plate form an L-shape.
  • the contact plate has at least two holes, viewed in the width direction of the domestic appliance and spaced apart from one another, for the passage of fastening elements. These fasteners are in particular screws. In one exemplary embodiment, these two holes are formed at the same height on the contact plate, viewed in the height direction of the household appliance. However, a related height offset can also be formed.
  • these holes are formed symmetrically to a vertical axis of the bearing bracket, this vertical axis being formed in the center of the bearing bracket when viewed from the front.
  • these holes are thus formed symmetrically to a center of the contact plate.
  • the bearing bracket has a bearing pin.
  • the bearing pin is in particular formed in one piece on the bearing bracket. “In one piece” here and in the following is to be understood in particular as being formed from one piece, for example by casting, injection molding or reshaping.
  • the bearing bolt preferably extends in the vertical direction. Viewed in the depth direction of the domestic appliance, the bearing bolt is arranged offset forwards with respect to the contact plate.
  • the bearing bolt is integrated in particular on the support plate mentioned above.
  • the bearing bolt extends with its longitudinal axis, which is oriented in particular in the vertical direction of the household appliance, perpendicular to the plane in which the support plate extends.
  • the bearing pin Viewed in the width direction of the household appliance, the bearing pin is arranged in a projection view or when projected into the contact plate from the front such that it is arranged centrally in relation to the contact plate, in particular in relation to the complete bearing angle. If holes are provided in the contact plate (e.g. for fastening the bearing bracket), it can be provided in particular that the bearing pin, viewed in the width direction of the household appliance, is arranged in a projection view or when projecting into the contact plate from the front such that it is centered between the holes is arranged in the contact plate. When the household appliance is viewed from the front and thus also when the bearing angle is viewed from the front, these holes in the contact plate are formed symmetrically to the bearing pin when viewed in the width direction.
  • an axis of symmetry can be seen in this regard, which extends in the height direction.
  • a distance measured in the width direction between the axis of symmetry of the bearing pin and one hole is equal to the corresponding distance between the axis of symmetry and the other hole.
  • the bearing pin is arranged symmetrically to this axis of symmetry. This configuration is particularly advantageous. Because of this symmetrical structure between the bearing pin and the holes arranged laterally thereto in a front-side projection view, the above-mentioned installation is possible in a particularly simple manner. On the one hand, the bearing bracket is simple and symmetrical in design.
  • the bearing bolt viewed in the width direction of the household appliance, is smaller than a smallest distance, measured in the width direction, between the two holes.
  • fastening elements can be easily inserted and mounted in these holes without the bearing bolt being in the way when viewed in the depth direction.
  • an assembly tool can simply be used to reach past the bearing bolt and the fastening element can be introduced into the holes arranged behind it and fastened.
  • this is correspondingly advantageous for screws that then have to be screwed accordingly.
  • the bearing bracket in particular the bearing bolt, defines an axis of rotation of the door arranged thereon.
  • the axis of rotation is arranged centrally between the holes when viewed in the width direction when projected into the contact plate.
  • the angle is always formed in such a way that an axis of rotation provided for the door is symmetrical to the holes. This also enables the corresponding symmetrical installation of the bearing bracket on the left-hand or right-hand side on the face of the front of the door and then also enables the same relative position of the door to the housing for both positions.
  • the bearing bracket has at least one, in particular integrated, positioning element. Viewed in the depth direction of the household appliance, this positioning element protrudes further to the rear than the contact plate. In one exemplary embodiment, this positioning element protrudes into a receptacle or an introduction in the face of the front of the housing.
  • a further mechanical coupling of the bearing bracket to the housing is thus achieved, in particular one interlocking coupling (e.g. a backlash-free interlocking coupling).
  • this also improves or enables the bearing bracket to be secured against twisting about an axis oriented in the depth direction. This further improves the fixing of the position of the bearing bracket on the end face of the front of the housing.
  • this positioning element is at a different height than the holes in the contact plate. This also supports the fixed position of the bearing bracket on the face of the front.
  • the introduction can be formed by a receptacle or a bore, for example a blind hole.
  • the hinge includes a cable routing device.
  • at least one cable of the household appliance can be laid or laid between the door and the housing by means of this cable routing device.
  • components that are arranged in the door can also be supplied with energy and/or data signals and/or a control signal, including an analog one.
  • the electronic components in the door can exchange signals with components in the housing and, in this respect, can in particular also communicate.
  • the proposed concept is particularly advantageous precisely in the case of such configurations of household appliances.
  • the cable routing device is thus built into the hinge and in this respect is also arranged in it in a space-saving and compact manner. An already existing interface between the door and the housing, which is formed by the hinge, is thus used multifunctionally.
  • the bearing bracket has an integrated bearing pin.
  • integrated is to be understood as meaning that the two elements are formed integrally, ie in one piece with one another.
  • the hinge has a bush that is separate from the bearing bracket.
  • the socket has at least one plug-in channel. This is intended for inserting the bearing pin into the bush. The bearing pin thus engages in this plug-in channel when installed. A corresponding mechanical coupling is thus also achieved.
  • the plug-in channel has an inner contour with a clamping structure.
  • the clamp structure is intended to be clamped with the bearing bolt. This allows a highly effective mechanical Coupling between the socket and the bearing pin can be achieved. In particular, a non-rotatable coupling between the bushing and the bearing pin is thus also achieved. A relative rotational movement between the bushing and the bearing bolt, in particular about the axis of rotation of the door, is thus prevented.
  • the clamping structure has at least one clamping pin, in particular two clamping pins, which interact in a clamping manner with the outside of the bearing bolt.
  • the socket is part of the cable routing device.
  • the socket then has a cable bushing.
  • This cable bushing can in particular be a cable duct.
  • this cable bushing is thus designed for the passage of a cable.
  • the cable is also arranged and routed in a particularly protected manner. Undesirable mechanical influences on the cable can thus also be avoided when the door is pivoted relative to the bearing bracket. Kinks or chafing on the cable during such a movement of the door can thus be prevented.
  • the plug-in channel of the socket is separated from the cable bushing of the socket.
  • the channels provided in this regard are separate from one another.
  • the cable is thus stored in a different channel than the bearing pin, which engages in the socket. Undesirable impairments of the cable can also be avoided in this way.
  • this also makes it possible for the bushing to be connected to the bearing pin in a mechanically stable manner. Coupling forces required for this can be generated independently of the cable, which is laid in the preferably different duct, namely the cable duct.
  • the bushing is fastened in a rotationally fixed manner to the bearing pin that is separate therefrom.
  • the bearing bracket is designed in one piece, in particular made of metal. It preferably has the contact plate, the carrier plate already mentioned and the bearing bolt. In one embodiment, the bearing bolt has a cuboid shape.
  • the hinge has an adapter part that is separate from the bearing bracket.
  • This adapter part is arranged in a rotationally fixed manner on a bearing bolt of the bearing bracket.
  • a bushing of the hinge that is preferably present is arranged seated on the adapter part that is separate therefrom, viewed in the vertical direction.
  • the mutually separate parts in the form of the bushing and the adapter part are thus arranged stacked on the bearing bracket, which is in turn separate therefrom, in particular placed on the bearing bolt and arranged stacked.
  • the adapter part acts together with a spring, in particular a plastic spring, of the household refrigeration appliance.
  • the plastic spring is attached to the door and slides over the adapter piece attached to the hinge when the door is closed. This generates a torque on the door, which closes the door or keeps it closed from a certain opening angle.
  • a stopper is mounted on the door together with a plastic spring which hits the adapter part and stops the door at a certain opening angle.
  • the household refrigeration appliance also has a partially automatic locking function.
  • a bearing bracket without a locking function is implemented. If the hinge has this additional adapter part, then a bearing bracket with a locking function is implemented.
  • the bearing bracket has the already mentioned and horizontally oriented support plate or coupling plate.
  • a stand of the household appliance that is separate from the bearing bracket is arranged directly, in particular fastened, on this coupling plate.
  • this base is screwed to the coupling plate.
  • the coupling plate has a threaded hole into which the base can be screwed with a threaded screw. This design not only allows the base to be attached to the bearing bracket, but also allows the base to be adjusted in height allows, this can be adjusted depending on the screwing position of the base in the thread of the threaded hole.
  • the coupling plate has a first section at a first height level (H1) and a second section at a second height level (H2) that differs from the first height level (H1).
  • the height levels are measured in the height direction (y-direction) of the household appliance.
  • the first portion and/or the second portion is preferably substantially or fully planar (notwithstanding e.g. additional embossing to increase rigidity) and/or preferably horizontally oriented. This configuration not only increases the stability of the bearing bracket. Rather, the two sections that are offset in the vertical direction create areas of the bearing bracket that advantageously enable different functions.
  • the first height level (H1) is greater than the second height level (H2) and the bearing bolt is formed on the first section or is formed adjacent to the first section and a threaded borehole accommodating the base is in the second section is trained.
  • the threaded hole lies completely below the first height level (H1). In this way, a sufficient distance between an upper end of the threaded screw on the one hand and a lower end of the door on the other hand can be made possible even when the base is in a completely screwed-in position. The threaded screw can therefore not collide with the door. On the other hand, however, a sufficient adjustment of the device height can still be achieved with the stand.
  • the bearing bracket is made of metal. In particular, it can be a sheet metal angle.
  • the separate adapter part is arranged on the bearing bolt in a rotationally fixed manner.
  • the adapter part has a feed-through hole through which the bearing bolt extends.
  • the adapter part can also be screwed to the bearing bracket, in particular the coupling plate or the carrier plate.
  • the socket is then placed on this adapter part, which here then can also be referred to as a normally open socket, attached. It too is then attached to the bearing pin.
  • the holes in the contact plate are arranged in such a way that these holes can be accessed even when the bushing is already mounted on the bearing bolt and screws can be inserted into the holes in the contact plate with a tool, for example a screwdriver. In particular, this can also take place when viewed in the depth direction of the household appliance and a corresponding assembly of the screws in the depth direction past the socket can be made possible.
  • the hinge is constructed in such a way that the holes in the contact plate are also accessible when the door is already arranged on the hinge. Access to these holes and fitting with screws can then also take place, which can then also be correspondingly screwed with a tool.
  • the exemplary embodiments already mentioned above with at least one positioning element on the bearing bracket can also be implemented in such a way that a plurality of positioning elements are present. Since such a bearing bracket is produced by forming and/or stamping, these positioning elements can also be produced at no cost. They can easily be generated at the same time as this forming and/or stamping process. In particular, no additional material is required for this.
  • the positioning elements can also be formed by separate pins which are non-detachably attached in the bearing bracket.
  • pressing into receiving holes in the contact plate can be provided here.
  • the coupling plate can have embossing. This increases the torsional rigidity.
  • the adapter part has an indentation that is open at the edge. This makes it easy to guide the cable past the adapter part. at In this exemplary embodiment, the cable then does not have to be passed through a hole that is closed all the way around or on the peripheral side.
  • the cable bushing in the socket is not circular but oval in cross section.
  • the upper end and/or the lower end of this cable bushing can be rounded. This avoids sharp edges or corners. This avoids damage to the cable.
  • the adapter part is designed for installation on the bearing bracket in a symmetrical manner. When the door hinges are changed, it can thus be removed from the bearing bracket, rotated by 180° and reinstalled on the bearing bracket.
  • the contact plate protrudes in the same direction from the coupling plate or the carrier plate as the bearing bolt.
  • a U-like shape of the bearing bracket is thus formed. Since the bearing pin protrudes around the contact plate in the same direction from the coupling plate or the carrier plate, the height of the bearing angle is also reduced compared to exemplary embodiments in which the bearing pin protrudes from the coupling plate in a positive vertical direction and the contact plate from the coupling plate in a negative vertical direction protrudes.
  • the design of the hinge also improves the automatic attachment, eg gluing, of the base, in particular a cardboard base of the housing of the household appliance. Because there is no longer any space for the hinge screwed from below on the bottom of the device.
  • the bearing bracket is attached and screwed exclusively from the front or the screw connection is only provided on the face of the front.
  • the installation position of the base of the household appliance is no longer directly on the housing, but rather on this bearing angle, also means that this base no longer has to be reached under the housing during assembly.
  • the installation position of the base is thus shifted forward when viewed in the depth direction. This also means damage to the bottom of the case, in particular if it's made of cardboard, avoided.
  • the door is thus also better protected against damage from the adjustable foot or the pedestal when it is being installed. The possibility of the device tipping over when installing the base is also reduced.
  • the advantageous exemplary embodiment with the cable routing in the hinge also makes it easy to install electronic components, an operating and/or display unit and/or a camera or the like in the door.
  • this cable only has to be threaded through the advantageously designed bushing, but no longer has to be guided all the way through other components of the hinge.
  • the exemplary embodiments mentioned also create a standard system as a hinge, which can be used both for household appliances with such a cable and without such a cable. This is also possible both for devices with a closer in the area of the hinge and without such a closer in the area of the hinge.
