HINGE ARRANGEMENT AND FURNITURE OR HOUSEHOLD APPLIANCE

Description

State of the art

[0001] In the case of furniture and household appliances with swivel elements that can be movably mounted on them, such as e.g. Various arrangements are known for the movable attachment of the pivot element to the body of a piece of furniture or household appliance, such as doors or flaps. In the operating state of the furniture or household appliance, the pivot element is movable relative to the body, for example, about a horizontally or vertically oriented pivot axis via the hinge arrangement, in order to allow access to an interior of the body and / or the pivot element and, when the pivot element is closed, to separate the interior from the outside. The pivot element is regularly e.g. Can be moved manually and / or powered.

[0002] In furniture and household appliances such as cabinets, refrigerators, and freezers, compact and mechanically stable hinge assemblies are specifically designed for their intended use. This allows a standardized and proven hinge assembly to be used in a wide variety of applications. The hinge assembly is typically attached to the cabinet body and the pivoting element. For mass-produced items like refrigerators and freezers, it is desirable to design and prepare both the furniture or appliance and the hinge assembly accordingly, thus enabling standardization. This allows proven hinge assemblies to be used universally, unchanged in their design, for a multitude of different furniture and household appliances, which is both economical and advantageous during assembly.

[0003] The state of the art is defined in CN 110685524 A , DE 102020112492 A1, US 2007 / 186480 A1 and WO 2010 / 105281 A1. Purpose and advantages of the invention

[0004] The object of the present invention is to further improve a hinge arrangement mentioned above and / or an associated piece of furniture or household appliance from an economic and technical perspective, in particular with regard to increased ease of use for the user.

[0005] This problem is solved by the features of claim 1. The dependent claims relate to expedient and advantageous further developments of the invention.

[0006] The invention relates to a hinge arrangement comprising a drive device and a hinge with a hinge arm, wherein the hinge is designed to move a pivoting element of a household appliance or a piece of furniture, wherein the pivoting element can be movably received on a body of the household appliance or furniture via the hinge, wherein one side of the hinge is designed for attachment to the body and another side of the hinge is designed for attachment to the pivoting element, wherein the drive device has a drive motor unit designed for arrangement on the pivoting element and wherein an end section of the drive motor unit is coupled to the hinge arm, so that the pivotally mounted hinge arm of the hinge can be set in motion by the drive motor unit in such a way that, in the assembled state of the hinge arrangement, a movement of the pivoting element relative to the body takes place.For example, the hinge assembly is a motorized hinge, such as an electric door opener or an electric hinge, for example, for automatically moving refrigerator doors, freezer doors, or the like. For example, the hinge assembly has a standard hinge designed to be mounted via two end sections of the hinge to a hinge-prepared section on the cabinet and to a hinge-prepared section on the pivot element. For example, the hinge includes exactly one hinge arm, exactly two, exactly three, or more than three hinge arms that are articulated and movable on the hinge. For example, the multiple pivot axes of the hinge arm or arms are aligned parallel to each other. For example, the hinge is a multi-joint hinge, such as a four-, five-, or six-joint hinge.For example, prepared sections are provided at both ends of the hinge, such as a flat contact surface for mounting against the pivot element on one side and the cabinet on the other. The contact surface has at least one opening or through-hole, such as a through-hole or a screw receptacle, by means of which the hinge, or one side of the hinge, can be detachably but securely attached to the cabinet on one side and the pivot element on the other, for example, by screwing it in place. A fastener, such as a screw, engages through the through-hole and into a material area of ​​the pivot element or into material of the cabinet.For example, the one or more through holes on the hinge are through holes that are already standard on a known hinge for mounting on furniture or household appliances. For example, the through holes can be used additionally or exclusively for connecting the hinge to a flange component, e.g., with a screw that engages the flange component and the mounting surface, and then engages the material of the pivot element or the body, connecting the respective sections. For example, a pivot element might have exactly one hinge assembly with its corresponding hinge and exactly one other hinge, i.e., exactly two hinges. For example, the two hinges might be similar in function and design, e.g., identical. For example, the drive device might be an electric motor, e.g.,...A linear actuator or, for example, a spindle drive. For instance, the drive device is a linear actuator with a linearly reciprocating actuating element, such as a push rod. For example, the actuating element is implemented by a driven rotating spindle or is moved linearly by one. The actuating element is mechanically coupled to the hinge arm, for example, via a motion coupling. For example, the actuating element is part of a lever assembly. The actuating element can be coupled to the hinge, for example, via a receptacle on the hinge arm, which includes, for example, an externally accessible screw or mounting contour on the hinge arm. Alternatively, the actuating element can be coupled to the hinge via a screw-on or plug-in contour accessible from the outside on the mounted hinge, for example, with a screw-in or plug-in opening on the hinge arm.For example, the hinge is designed to function correctly without the drive motor unit, providing a pivoting motion of the pivoting element. For example, the hinge is a standard hinge. For example, the hinge is designed without a drive device acting on the hinge arm or any other drive device such as a drive motor, so that the pivoting element is movable relative to the body when an external pulling or pushing force is applied to the pivoting element, for example, by a person. The hinge allows the pivoting element to pivot in two opposite directions relative to the body.

[0007] For example, in a hinge arrangement with a drive device, when the coupled actuator moves towards the hinge, the pivoting element is driven away from the cabinet from a closed position (e.g., a position close to the cabinet) by the drive device. When the actuator, coupled to the hinge arm, moves away from the hinge, the pivoting element is forced towards the cabinet from a position open (e.g., an open position) by the driven movement of the hinge arm. The drive device can be switched accordingly.

[0008] Optionally, a coupling is provided between the drive unit and the hinge arm. For example, a reduction or step-down gearbox, or another type of gearbox, and / or a coupling such as a slip clutch and / or an overload clutch may be present.

[0009] For example, the cabinet-side end of the hinge engages with a cabinet mounting arrangement of the hinge, for instance, in the area of ​​a cabinet edge that is vertical in the usable state. This edge is formed on the outside of the cabinet between a lower section on the front of the cabinet and a section on a side panel adjoining the front panel. For example, the mounting arrangement includes an element with legs, such as an angle element with legs that are perpendicular to and connected to each other. One leg of the angle element engages the section on the front panel, and the other leg engages the section on the side panel. For example, the vertical cabinet edge and adjoining sections are engaged at the bottom right or bottom left of the cabinet, depending on whether the pivot element is hinged or pivoted on the right or left side of the cabinet.Elements of the hinge extend from the leg at the front towards the pivot element or the fastening element of the hinge that can be attached to it.

[0010] The core of the invention lies in the fact that a first flange component and a second flange component are provided for arranging the drive motor unit on the swivel element, wherein the drive motor unit can be arranged on the swivel element by means of the first flange component and by means of the second flange component, wherein the first flange component and the second flange component each have an attachment section for fastening the respective flange component and each have a coupling section for coupling the drive motor unit to the respective flange component, wherein in the arranged state of the flange components on the swivel element the coupling section of the first flange component and the coupling section of the second flange component are aligned towards each other, so that the two flange components are symmetrically arranged, wherein the drive motor unit is located between the first flange component and the second flange component.

[0011] For example, the drive motor unit is in direct contact with the coupling section of the first flange component. For example, the drive motor unit is in direct contact with the coupling section of the second flange component. For example, the drive motor unit is in direct contact with the coupling section of the first flange component. For example, the drive motor unit is in direct physical contact with, or touching, a section of, the coupling section of the first flange component.

[0012] Alternatively, for example, the drive motor unit is indirectly in contact with the coupling section of the first flange component. For example, the drive motor unit is indirectly in contact with the coupling section of the second flange component. For example, the drive motor unit is in indirect contact with the coupling section of the first flange component at one point.

[0013] For example, the hinge assembly comprises the hinge with, for example, exactly one pivotally mounted hinge arm or with several pivotally mounted hinge arms. The hinge is, for example, a multi-joint hinge or a four- or five-joint hinge. For example, the hinge assembly comprises the drive device and the flange components. For example, a swivel element is pivotally mounted to the body with an additional hinge. For example, exactly one drive device is usually sufficient to move exactly one swivel element. For example, the swivel element is pivotally mounted to the body via exactly two pivot bearing points, each with a hinge.

[0014] For example, exactly two flange components are provided. For example, the two flange components are designed as mirror images of each other. For example, the two flange components are provided on outer sections of the drive motor unit, such as at the longitudinal ends of the drive motor unit, e.g., at opposite longitudinal ends of the drive motor unit. The mounting between the two flange components allows for the economically advantageous attachment of the drive motor unit to the pivoting element. Furthermore, mounting the drive motor unit to the pivoting element is simple. For example, the flange components are designed to be mounted on the pivoting element, for example, in the lower edge area on a flat inner surface of a refrigerator door or in the area of ​​a narrow horizontal underside of the refrigerator door.Due to the two separate flange components, their positioning on the swivel element is easily and individually variable and adaptable. For example, the flange components can be adjusted to the length of the drive motor unit. Both flange components can be attached to the swivel element using the same fastening method, such as corresponding screws or plug-in fasteners, so that only one type of fastener is required. This also simplifies installation. The symmetry of the flange components is related to the hinge arrangement. For example, the two separate flange components are not identical. For example, the two flange components are designed as mirror images. For example, the flange components are aligned with each other along their respective longitudinal axes at the hinge arrangement and thus, when mounted on the swivel element.For example, the longitudinal axes of the two flange components lie on a common spatial axis, thus facilitating the attachment of the hinge assembly to the pivot element. For example, the two flange components are spaced apart to provide an area in which the drive motor unit is appropriately positioned. For example, the drive motor unit and the flange components are designed so that the drive motor unit can be detachably connected to the two flange components. Preferably, opposing sections of the drive motor unit can be connected to the respective coupling sections of the flange components. For example, end sections of the drive motor unit can be connected to the respective coupling sections of the flange components. Each section of the drive motor unit can be connected to the respective coupling section of the flange components, for example, by snapping, plugging, and / or clamping.For example, each coupling section has an elastically flexible coupling section that can be connected to a matching counterpart section. Alternatively, each coupling section may have an elastically flexible coupling section that can be detachably locked to, for example, a rigid detent section matching the coupling section on the respective end section of the drive motor unit. For example, the detent may be fixed but externally releasable, e.g., by manual action, such as applying a release force to the coupling section. For example, the drive motor unit may be detachably mounted on the two flange components. For example, the drive motor unit may be clamped or detented on the two flange components. This is the case, for example, in the installed, functional state of the hinge assembly on the furniture or household appliance.

[0015] During assembly of the hinge assembly, the drive motor unit can initially be separated from the rest of the hinge assembly, which simplifies the process. The two flange components, for example, are easier to transport, select, and mount on the pivot element without the drive motor unit attached. Only the alignment, such as the coincidence of the longitudinal axes to a common spatial axis, and the distance between the two flange components on the pivot element need to be observed during assembly.

[0016] For example, of the two flange components, exactly one flange component, which faces away from the pivoting element side of the hinge, can be attached to the pivoting element without contact with the hinge, at a corresponding distance from the pivot arm. The drive motor unit is then located within this distance in the fully assembled state. For example, the other flange component is attached to the hinge, such as to a mounting element of the hinge. For example, the mounting element serves to attach the corresponding side of the hinge to the pivoting element. For example, the other flange component, which is, for example, a flange component near the hinge arm, can also be attached directly to the pivoting element. For example, connecting elements such as screws are provided, via which the common orSimultaneous connection of the other flange component to the swivel element and also to the fastening element of the hinge is established.

[0017] For example, both flange components are designed as an additional component, such as an adapter, for a complete, non-driven hinge, such as a conventional hinge or a hinge assembly, and can be additionally attached to it. For example, starting from such a known hinge or hinge assembly that does not include a drive device or drive motor unit, the hinge arrangement according to the invention can be designed. For example, a known hinge can be retrofitted with a drive motor unit. This allows, for example, a simple retrofit of a refrigerator with a conventional hinge. For example, a known hinge for a non-motorized refrigerator door can be easily retrofitted so that the refrigerator door can be moved automatically or electrically with the retrofitted hinge.

[0018] For example, a well-known hinge mechanism can be retrofitted with a drive device or drive motor without any modifications to the hinge mechanism itself.

[0019] For example, the flange components are attached to the pivoting element in the operating state of the hinge arrangement. e.g.The flange components are linearly offset from each other in the same orientation or spaced apart along a line. For example, both longitudinal axes of the flange components coincide or are parallel and offset from each other, e.g., within one width or half the width of the drive motor unit. For example, the drive motor unit is mounted between the separate flange components. The two coupling sections are aligned with each other when mounted on the pivot element, e.g., perfectly aligned. For example, the longitudinal axis of the drive motor unit is perpendicular, e.g., at a right angle or at an angle to a pivot axis of the hinge or perpendicular to a pivot axis of the hinge arm.

[0020] For example, every flange component in its basic form is designed as an angled element with, for example, exactly two, three, or more than three mutually oriented, flat sections. For example, one section forms the mounting section, and another section forms the coupling section. For example, the coupling section is formed by exactly one section or by exactly two or more than two mutually angular sections.

[0021] The flange component is designed, for example, as an angle element. The flange component is made, for example, of sheet metal and / or plastic.

[0022] For example, in the arranged state of the drive motor unit on the swivel element, the coupling section of the first flange component and the coupling section of the second flange component are aligned towards each other, so that the two flange components are mirror-symmetrical.

[0023] For example, a mirror plane exists with respect to the coupling section of the first flange component and the coupling section of the second flange component. For instance, the respective narrow sides of the mounting section and the coupling section point towards each other or are aligned with each other. This facilitates easy assembly of the hinge assembly with the drive device on the pivot element. For example, a corresponding mirror plane lies at the midpoint of a distance between the two flange components in the longitudinal direction of the flange components or in the longitudinal direction of the drive motor unit. The mirror plane is, for example, perpendicular to the longitudinal direction of the drive motor unit. For instance, the two flange components are designed to be mirror-symmetrical in shape relative to each other.

[0024] For example, the coupling section of the first flange component and the coupling section of the second flange component are identically designed. This simplifies assembly. For example, it is possible to have the same design at both points on the drive motor unit, e.g., at opposite longitudinal ends, where the coupling section engages. For example, the coupling section is a thin and / or flat and / or planar section. For example, the coupling section has a straight leading edge with flanks that connect at right angles on both sides.

[0025] For example, the coupling section is connected to the drive motor unit via two spaced-apart connection or bearing points of the coupling section.

[0026] This allows, for example, a multi-point mounting such as a two-point mounting. The connection via the coupling section is designed to be detachable, for example, by plugging it in. The two bearing points enable a variable connection to the drive motor unit. For example, one bearing point on the coupling section of the flange component is designed so that a different type of mounting is possible between the flange component and the drive motor unit. For example, a bolted connection is possible, such as a bolted connection to the other bearing point.

[0027] For example, the other flange component is connected to the corresponding side of the drive motor unit via the coupling section, for example by plugging it in.

[0028] For example, the mounting section of the first flange component and the mounting section of the second flange component are identically designed. This allows for a uniform connection method, e.g., to the pivot element. For example, the mounting section of the flange component connects to one side of the hinge. This connection to one side of the hinge is made, for example, to a fastening element, such as a fastener of the hinge itself.

[0029] For example, the first flange component engages a first end section of the drive motor unit, and the second flange component engages a second end section of the drive motor unit, with the first and second flange components being spaced apart. This provides stable support. For example, a two-point support or two-point mounting of the drive motor unit is provided. For example, the second end section of the drive motor unit can be attached to the pivot element via the second flange component. For example, the first end section of the drive motor unit can be attached to a section of the pivot element spaced away from the hinge via the first flange component. For example, the first flange component provides an additional mounting option for the drive motor unit on the corresponding side of the hinge.For example, the first flange component is set up to attach the pivot-element-side side of the hinge to the pivot element.

[0030] For example, the mounting section and the coupling section are aligned at an angle to each other. For example, the flange component is a bent sheet metal element.

[0031] For example, the mounting section and the coupling section are both plate-shaped. Their angled shape provides mechanical stability and enables the drive motor unit to be securely attached to the pivot element and / or the corresponding side of the hinge. When attached to the pivot element, such as the inside of a refrigerator door, the coupling section extends, for example, perpendicular to the plane of the inside of the pivot element. Similarly, when attached to the pivot element, such as the inside of a refrigerator door, a flat and / or planar side of the mounting section extends parallel to the plane of the inside of the pivot element.

[0032] For example, the mounting section and the coupling section are oriented at an angle to each other, e.g., at right angles. For example, a surface of the mounting section and a surface of the coupling section are connected to each other via an edge section, such as a bending edge. For example, the edge section runs aligned with the longitudinal axis of the drive motor unit, e.g., parallel to the longitudinal axis of the drive motor unit.

[0033] For example, the mounting section is designed for connection with a fastening element, which serves to attach the other side of the hinge to the pivot element. This allows the relevant flange component to be connected to the hinge securely and appropriately, ensuring the precise and stable positioning of the drive motor unit relative to the remaining part of the hinge assembly. For example, the mounting section is formed integrally with the hinge.

[0034] For example, the mounting section has a flat section, such as a base. For example, the flat section of the mounting section is designed to engage the underside of the fastener. For example, the flat section is sandwiched between other flat areas. For example, the flat section is located between one side of the pivot element and one side of the fastener. For example, the flange component is connectable to the pivot element on one side and to the fastener on the other. For example, the corresponding side of the hinge is connected to the pivot element. For example, the fastener is a component of a standard hinge designed to attach the hinge to the pivot element.

[0035] For example, the mounting section has a base for flat contact with the swivel element and a web section formed above the base, with the web section separated from the base by a material-free area. This enables a variably adjustable and stable connection of the flange component to the swivel element on the one hand and to a counter section on the other. For example, the base serves to attach the flange component to the swivel element. For example, the base serves to screw the flange component to, for example, an inner surface of the swivel element. For example, the base rests with its underside against, for example, the inner surface of the swivel element. For example, the fastening element is supported on the top surface of the base. For example, the underside of a fastening element is supported on the top surface of the base.For example, the underside of the hinge is present to attach the corresponding side of the hinge to the pivot element. For example, the web section serves for further fixing or connection to the hinge and / or to sections of the drive motor unit. For example, the base and / or the web section each have a through-hole for a screw fastener. The through-hole allows the flange component to be attached to a counterpart section, for example, by screwing it on. For example, the flange component can be attached to a flange component on a section of the drive motor unit, for example, by screwing it on. For example, the flange component can be attached to the other flange component on the hinge, for example, by screwing it on. For example, the flange component can be attached to a part of the hinge that engages with the pivot element, for example, by screwing it on.

[0036] For example, the web section is a sheet metal section, e.g., a strip-shaped sheet metal section. The sheet metal section is, for example, freely cantilevered above the ground. For example, a free end of the web section is oriented opposite a free end of the coupling section. For example, the free ends are oriented in their respective longitudinal directions towards one and the other longitudinal side, for example, facing outwards in a common direction on the flange component. For example, both opposite longitudinal ends of the flange component serve to connect the flange component to other sections, such as sections of the drive motor unit. For example, on the hinge-side flange component, a section of the drive motor unit is detachably attached to one end of the coupling section.For example, another component engages at the free end of the web section; for example, a side of the hinge engages at the free end of the web section.

[0037] For example, on the flange component facing away from the hinge, in addition to the coupling section, the web section also serves to connect to other sections.

[0038] For example, in addition to the coupling section, the web section also serves for further attachment to or with the drive motor unit, which increases the connection stability. For example, the planes of the base on the one hand and the web section on the other, or the surface of the base and the surface of the web section, are aligned with each other, e.g., parallel to each other.

[0039] According to the invention, the drive motor unit is detachably mounted on the first flange component and / or on the second flange component by a connection that can be set without tools. This facilitates the assembly and disassembly of the drive motor unit between the two flange components.

[0040] For example, the drive motor unit is attached to the first flange component and the second flange component, or to both flange components, in the same manner, for example, by being plugged in the same way or otherwise detachably attached in the same way. For example, the attachment is achieved by a plug connection, clamp connection, and / or snap connection. The type of connection is, for example, a positive-locking detachable connection.

[0041] For example, the first flange component and / or the second flange component provides a stop in a longitudinal direction for the mounted drive motor unit. Additionally or alternatively, the first flange component and / or the second flange component provides a stop in a direction transverse to the longitudinal direction of the drive motor unit. For example, a fixed mounting position of the drive motor unit is established on the swivel element. In a further or third direction, perpendicular to the two aforementioned longitudinal directions and transverse to the longitudinal direction, or, for example, normal to the surface of the swivel element, the drive motor unit is supported by the flange component. The drive motor unit is supported, for example, on one side of the flange component. The drive motor unit is supported, for example, on the top surface of the base of the flange component.For example, the drive motor unit is permanently fixed to the furniture or household appliance in its operating state.

[0042] For example, the drive motor unit engages the hinge arm via a lever assembly. For example, the lever assembly establishes a coupling between the drive motor unit and the hinge arm. For example, a mechanical coupling is established between the drive motor unit and the hinge arm, with a motion coupling between a driven, movable part of the drive motor unit and the hinge arm. For example, the movable part of the drive motor unit is the push element, which has a motion coupling with the hinge arm. For example, the lever assembly engages at a point on the hinge that is easily accessible from the outside when the hinge assembly is mounted. For example, the easily accessible point on the hinge includes the receptacle on the hinge arm. For example, the engagement point or receptacle on the hinge arm is provided or prepared as standard.For example, this allows for the optional addition of a function to a known hinge, such as a damping function with a damper or for another additional component. For instance, the attachment point on a known hinge is used for the detachable docking of a damper to dampen movement at the hinge, ensuring a damped movement of the pivot element relative to the body.

[0043] For example, the one-piece or multi-piece lever assembly engages, on one side, a linearly movable push element of the drive motor unit, such as a push rod. On the other hand, the lever assembly engages, directly or indirectly, the hinge arm. For example, the lever assembly includes a component that can be attached separately to the hinge, such as a mounting element or adapter element, which may be made of a plastic material.

[0044] For example, the lever arrangement is designed such that, when the drive device is activated, the pivoting element moves relative to the body in an opening or closing direction, driven by the kinematics defined by the hinge. For example, the lever arrangement is designed such that during a linear forward movement of the push element, such as a push rod, driven by the drive motor unit, the hinge arm pivots around a hinge arm axis. For example, the movement of the hinge arm, via further hinge arms of the hinge, results in a pivoting movement of the pivoting element relative to the body, or leads to an opening movement of the pivoting element in an opening direction or in a closing direction opposite to the opening direction. The lever arrangement transmits a torque to the rotatably mounted lever arm of the hinge about its axis of rotation or pivoting.

[0045] For example, the lever assembly comprises a control lever that is pivotally connected to a mounting element of the lever assembly, the mounting element being detachably engaged with a receptacle on the hinge arm of the hinge. For example, the mounting element is a plug-in element that can be attached to a receptacle designed as a plug-in receptacle, for example, and locked into place. For example, the mounting element of the lever assembly provides a multi-point or two-point connection point for the control lever of the drive motor unit on the hinge arm. This achieves a space-saving and reliable coupling of the drive motor unit and the hinge arm of the hinge.

[0046] For example, the control lever is connected to the push element. For example, the control lever is connected to a push rod of the drive motor unit. For example, the location on the hinge arm includes a prepared contour that can be used for, or serves for, coupling the lever assembly to the hinge arm. For example, the contour includes two spaced-apart, shaped insertion openings in a top surface of the hinge arm. For example, the location on the hinge arm, such as the prepared contour, includes two differently shaped insertion openings in a top surface of the hinge arm. For example, the location on the hinge arm, such as the contour, includes a round opening and an oblong hole.

[0047] For example, the connection of a section, such as a mounting element of the lever assembly, to the hinge or hinge arm is made using a standard receptacle already present on the hinge. For instance, the standard receptacle already present on the hinge includes an opening that serves as a plug-in and / or screw-in receptacle and is known, for example, as a "Zamak receptacle".

[0048] For example, the control lever has a curved shape, for instance, for a hinged connection between the control lever and the mounting element. For example, the control lever includes two opposing, spaced-apart bearing points, for instance, for a hinged connection between the control lever and the mounting element. For example, the control lever has a curved shape and includes two opposing, spaced-apart bearing points. For example, the curved shape is relative to a side view. For example, in a top view and along the longitudinal axis of the drive motor unit, the control lever is straight. For example, the curved shape of the control lever bridges a height difference. For example, it bridges a height difference that is normal to the bottom of the flange component and / or, when mounted, to an inside side of the swivel element.For example, the height offset refers to different heights between a central longitudinal axis of the sliding element and the point on the hinge arm where the lever arrangement or the mounting element engages.

[0049] The invention also extends to a piece of furniture or household appliance with a body and a pivoting element movably mounted on the body, wherein a hinge arrangement according to one of the embodiments described above is provided for moving the pivoting element.

[0050] This allows the discussed features and advantages to be achieved in a piece of furniture or household appliance such as a refrigerator. Since it should be possible to optionally hinge the swivel element on the left or right side of the cabinet, a specially designed set of two flange components, or a left-side set with two matching flange components and a right-side set with two matching flange components, must be provided to allow the door to be hinged on either the right or left side of the cabinet.

[0051] Further features and advantages are explained in more detail with reference to the exemplary embodiments shown in the figures. Specifically, the figures show: Fig. 1 shows a schematic representation of a household appliance in a perspective view from the front with a pivoting element movably mounted on it via a hinge arrangement in an open position relative to a body of the household appliance; Fig. 2 shows a partially opened hinge of the hinge arrangement according to Fig. 1 with a mounting element in perspective view, Fig. 3 the arrangement according to Fig. 2 with a drive device indicated by dashed lines and shown in sections from the side in a first fully pivoted position in the state attached to a household appliance, which is shown partially and partially obscured, Figs. 4 to 7 the arrangement according to Fig. 2 without parts of the household appliance and the drive device from the side in different pivot positions, Fig. 8 shows a section of the hinge arrangement according to Fig. 1with a drive motor unit, with two flange components and a cutout of one side of the hinge, Fig. 9 the cutout A in Fig. 8 enlarged, Fig. 10, section B in Fig. 8 enlarged and Fig. 11 the two flange components according to Fig. 8 , whereas opposite Fig. 8 The interrupted and partially shown drive motor unit and the section of the side of the hinge are only indicated by dashed lines.

[0052] Fig. 1 Figure 1 schematically shows a household appliance 1, for example a refrigerator, with a body 2 and a pivoting element 3 movably mounted on the body 2, which in the exemplary embodiment forms a refrigerator door of the refrigerator.

[0053] To move the swivel element 3 in an opening direction P1 and a closing direction P2 relative to the housing 2, a hinge arrangement 4 with a hinge 5 at the bottom, on the front right of the appliance 1, is provided. The swivel element 3 is accordingly hinged on the right side of the refrigerator. At the top right of the appliance 1, a hinge 11 corresponding to the hinge 5 acts between the housing 2 and the swivel element 3. The hinges 5 and 11 are, for example, standard hinges, such as multi-joint hinges like a hinge assembly, e.g., a wide-angle hinge with several pivotally mounted hinge arms.

[0054] The two hinges 5, 11 form a movement or pivot bearing of the pivoting element 3 on the body 2. The two hinges 5, 11 are each positioned between the body 2 and the pivoting element 3 in such a way that, in the installed state of the household appliance 1, both hinges 5, 11 form a common vertical pivot axis S about which the pivoting element 3 can pivot back and forth relative to the body 2 in the directions P1 and P2.

[0055] The swivel element 3 can be moved from a closed position on the body 2, which Fig. 3 This indicates that, with a pivot angle of 0 degrees between a front vertical surface of the body 2 and a vertical inner or outer surface of the pivoting element 3, the openings in the direction of P1 will be adjusted or opened to varying degrees relative to the body 2. The further Figures 4 to 7show the successively opening hinge 5 in its different opening positions without body 2 and without swivel element 3.

[0056] Accordingly, it shows Fig. 4 a position of the hinge 5 corresponding to a pivot position of the pivot element 3 or a partially open position of the hinge 5, in which the pivot element 3, starting from the closed state at zero angle degree position according to Fig. 3 would be partially opened or pivoted by 20 degrees in the direction of P1 towards the body 2 or its vertical front.

[0057] Accordingly, it shows Fig. 5 a position of the hinge 5 or a partially open position of the hinge 5, in which the pivoting element 3, starting from the closed state, according to Fig. 3 would be partially opened or swivelled at an angle of 45 degrees to the body 2 or its vertical front.

[0058] Accordingly, it shows Fig. 6a position of the hinge 5 or a partially open position of the hinge 5, in which the pivoting element 3, starting from the closed state, according to Fig. 3 would be partially opened or swivelled at an angle of 90 degrees to the body 2 or its vertical front.

[0059] Finally, it shows Fig. 7 a position of the hinge 5 or a partially open position of the hinge 5, in which the pivoting element 3, starting from the closed state, according to Fig. 3 would be fully opened or pivoted to its maximum extent by 115 degrees relative to body 2 or its vertical front.

[0060] The hinge arrangement 4 comprises the hinge 5, which includes a hinge arm 6 and further unspecified hinge arms, a drive device 7 and flange components 12, 13.

[0061] The flange component 12 according to Fig. 2-7 is designed as an alternative to the flange component 12 according to Figs. 8-11 .

[0062] The hinge 5, as well as the upper hinge 11, forms the basic mechanical unit for moving the swivel element 3 of the household appliance 1. All joint axes of the hinge arms are aligned parallel to each other, as with standard hinges. One of these joint axes coincides with the swivel axis S (see figure). Fig. 4 ).

[0063] The pivoting element 3 is movably mounted on the body 2 via the hinge 5. One side 9 of the hinge 5 is designed for attachment to the body 2, and another side 10 of the hinge 5 is designed for attachment to the pivoting element 3. The drive device 7 (see Fig. 8 ) has a drive motor unit 8, which is designed for arrangement on the pivoting element 3. The drive device 7 is designed as an electric drive device.

[0064] A longitudinally viewed end section 8a of the drive motor unit 8 is coupled to the hinge arm 6, which Figs. 8 and 9 Figure 7 shows in more detail. In an energized drive operation of the drive device 7, the drive device 7 is supplied with power via a connection (not shown) to an energy supply arrangement, e.g., internally within the drive device 7 with an energy storage device such as a battery and / or externally with an electrical cable supply. With the drive motor unit 8 activated and energized, the articulated hinge arm 6 can be moved into a pivoting motion S3 about a hinge arm pivot axis during the opening process of the pivoting element 3 (see Figure 8). Fig. 4 ), wherein the hinge arm pivot axis coincides with the pivot axis S of the pivot element (see Fig. 4). Thus, in the assembled state of the hinge arrangement 4 and the hinge 11 on the household appliance 1, the pivoting element 3 moves relative to the body 2 in the direction of P1 or, if the hinge arm 6 is turned in the direction opposite to the direction S3, in the closing direction P2.

[0065] Accordingly, the hinge arrangement 4 is designed as a motorized hinge, for example as an electric door opener such as a refrigerator door opener.

[0066] Two separate flange components 12 and 13 are provided for mounting the drive motor unit 8 on the pivot element 3. The flange components 12 and 13 are, for example, additional or separate components for the hinge 5. Alternatively, the hinge-side flange component 12 could also be formed integrally with the side 10 of the hinge 5. The drive motor unit 8 can be mounted on the pivot element 3 by means of the flange components 12 and 13. The drive motor unit 8 is received at each end on opposite longitudinal end sections of the drive motor unit 8 between the two flange components 12 and 13. Attaching and removing the drive motor unit 8 from the two flange components 12 and 13 is advantageously done manually with a simple assembly operation, for example, by a technician.

[0067] Both flange components 12 and 13 each have a mounting section 14 for attaching the flange component 12, 13 to the pivot element 3 and a coupling section 15 for coupling the drive motor unit 8 to the flange component 12, 13. The mounting section 14 and the coupling section 15 are each flat, planar sections, for example, sheet metal sections, if the flange component 12, 13 is made of sheet metal. The mounting section 14 and the coupling section 15 are, for example, at right angles to each other. The mounting section 14 and the coupling section 15 are, for example, integrally connected to each other in the area of ​​a bending edge.

[0068] In the arranged state of the flange components 12, 13 on the pivot element 3, the two coupling sections 15 are aligned towards each other. For example, the respective narrow sides of the mounting section 14 and the coupling section 15 point towards each other. The two flange components 12 and 13 are symmetrical. A corresponding mirror plane E is in Fig. 11 hinted at.

[0069] How in particular the Figures 8 and 11 To illustrate, in the arranged state of the drive motor unit 8 on the pivoting element 3, the two coupling sections 15, or rather their narrow end faces, are aligned towards each other on the flange components 12, 13 attached to the pivoting element 3. Thus, the two flange components are mirror-symmetrical with respect to the plane E.

[0070] The sides 9 and 10 of the hinge 5 each have openings 16, e.g., screw holes for the insertion or passage of fasteners such as screws, and / or recesses 17 for attaching the hinge 5 to the household appliance 1. The openings 16 and recesses 17 are standard features of standard hinges and can also be used in the hinge arrangement 4, for example, in conjunction with the standard mountings for the fasteners already provided on the household appliance 1, the body 2, and the swivel element 3. For this purpose, side 10 of the hinge 5 has a flat and / or plate-like fastening element 10a with, for example, exactly two spaced-apart openings 16. The flange component 12 can also be connected to side 10 of the hinge 5 via the recess 17 and / or the openings 16.

[0071] The drive motor unit 8 engages the hinge arm 6 of the hinge 5 via a lever assembly 18. The lever assembly 18 establishes a coupling between the drive motor unit 8 and the hinge arm 6. This coupling is a mechanical coupling and includes a motion coupling, e.g., a kinematic coupling between elements of the drive motor unit 8 on the one hand and the hinge 5 on the other. The movement of a driven, movable part, such as one shown in the figures, is thus achieved. Fig. 9 The concealed linearly movable push rod of the drive motor unit 8 causes a movement coupling with the hinge arm 6, which can thereby pivot about a hinge axis of the hinge 5 or about the pivot axis S. Depending on the drive direction of the push rod, the hinge arms are thus opened or closed, and the pivot element 3 is thereby pivoted relative to the body 2 in the respective direction P1 or P2.

[0072] The lever assembly 18 has a control lever 19, which is connected to a linear element of the drive motor unit 8, e.g., a push rod. The control lever 19 is pivotally connected to an attachment element 20, such as a plug-in element of the lever assembly 18. The attachment element 20 engages, for example, by screwing or snapping, a receptacle 21 on the hinge arm 6 of the hinge 5. The receptacle 21 is a standard feature of the hinge, e.g., easily accessible from the outside, as a plug-in and / or screw-in receptacle, and can be used to connect the drive motor unit 8 via the lever assembly 18.

[0073] The control lever 19 has a curved shape and comprises two opposing, spaced-apart bearing points at its hinge-side end section for a pivotal connection with the mounting element 20. The control lever 19 is pivotally articulated about a pivot axis G (see figure). Fig. 2) connected to the mounting element 20, which is fixedly attached to the hinge arm 6. For this purpose, for example, aligned round openings are provided, two on the mounting element 20 and two on the control lever 19, through which a joint element, such as a joint pin 22, passes and is axially secured.
