Definitions
- the invention relates to a hinge element for a large household appliance, comprising a base body and a functional body made of plastic.
- Large household appliances typically have an accommodating space arranged in a body and a door arranged on the corpus for opening or closing the accommodating space.
- Examples of such large household appliances are refrigerators (refrigerators, freezers, chest freezers, wine storage cabinets, fridge-freezers), dishwashers, cooking appliances or washing machines.
- a hinge element for the rotatable mounting of the door, which hinge element has a base body that is typically fastened to the body. It is known to provide this hinge element with a functional body made of plastic.
- the functional body typically forms a bearing bolt that is accommodated in a corresponding bearing bush of the door.
- EP2281095A1 discloses a hinge element for a door of a household appliance, the hinge element having a mounting section for mounting on a body of the household appliance, a support arm protruding from the mounting section and bearing elements arranged at the free ends of the support arm, with at least one of the two bearing pins of the hinge element being non-rotatably in one made of plastic bearing pin is included, which is mounted in a bearing eye fixed to the door.
- the object of the present invention is to provide a hinge element which has improved precision compared to the known hinge elements and is nevertheless simple and inexpensive to produce.
- the object is also to provide a large household appliance which, compared to the known large household appliances, provides a more precise connection of the door to the body and can be produced easily and inexpensively.
- the invention is based on a hinge element for a large household appliance, ie a large household appliance hinge element.
- hinge elements are characterized in that they withstand the high impact of force over a long life cycle on the one hand due to their dimensioning and on the other hand due to the materials used.
- Such hinge elements have to withstand weight forces of a closure element of up to 70 kg over 200,000 opening cycles without any noticeable impairment of the function occurring.
- the hinge element serves to attach a closure element of a large household appliance to a body of the large household appliance, i.e. to fasten it in a rotatable manner.
- the closure element can in particular be a door or a flap which, arranged on the outside of the body, closes a receiving space (for example for food).
- the hinge element comprises a base body on the one hand and a functional body on the other hand.
- the base body in particular designed as an inherently rigid component, preferably forms a main element of the hinge element and serves to transmit the forces acting on the hinge element safely and reliably (in particular without deforming the hinge element that would impair its function) between the closure element and the body.
- the functional body represents an additional element of the hinge element, which enables at least one function necessary for the hinge element (e.g. providing a sliding surface, providing a support surface, providing a stop).
- the base body and the functional body have different materials or are made of different materials.
- the base body and the functional body are permanently connected to one another.
- a non-detachable connection is to be understood as meaning a connection that no longer allows the base body and the functional body to be dismantled or separated or detached from one another except by destroying the base body and/or the functional body and/or a connecting means (e.g. adhesive) located between them.
- the inseparable connection thus forms a non-destructively non-detachable connection or a non-destructively detachable connection.
- the present invention is based on the finding that the non-detachable connection enables very precise positioning of the functional body in relation to the base body.
- distances or angles between specific points or surfaces, which lie on the one hand on the base body and on the other hand on the functional body can be precisely fixed or defined during the manufacture of the bearing element.
- a very precisely working bearing element can be provided.
- the non-detachable connection also allows this high level of precision to be maintained over a long period of use.
- the non-detachable connection also prevents minimal movements between the base body and the functional body during operation. Abrasion in the area where the base body and functional body are connected can be prevented. If the functional body forms a bearing bolt, for example, an undesirable co-rotation of the bearing bolt relative to the base body can also be prevented.
- the production of large household appliances is simplified with a hinge element according to the invention, since the hinge element is easier to handle and assemble as a one-piece component. Since it is not necessary to attach a separate functional body as an additional work step, there is no risk of the base body and functional body being joined together incorrectly. Due to the non-detachable connection, an unintentional detachment of the functional body from the base body during the manufacture of the large household appliance is also ruled out. If the door hinges are changed at a later point in time, in particular by an end user, in which case the hinge element must be detached from the body and attached again on an opposite side of the body, the risk of the functional body accidentally detaching from the base body is also ruled out. Thus, there is also no possibility of incorrectly attaching a detached functional body to the base body.
- the non-detachable connection between the base body and the functional body can take place, for example, by means of a material connection between the base body and the functional body.
- the base body and the functional body are glued together.
- spray adhesive or liquid adhesive can be used as the adhesive.
- the functional body made of plastic is glued directly to or onto the, e.g. metallic, base body.
- the functional body is also conceivable for the functional body to be formed by two preassembled components which are designed separately from one another and each have plastic and which are glued directly to one another (e.g. an upper and a lower half as two preassembled components). Combinations of both variants are also conceivable.
- the functional body is formed by a coating of the base body.
- the coating can be formed by a sliding layer.
- the coating can be sprayed on, for example, and/or have a layer thickness of less than 1 mm.
- the non-detachable connection between the base body and the functional body takes place by means of a form-fitting connection of the base body and the functional body.
- the functional body is formed by an overmolding, in particular at least in sections, of the base body or that the functional body on the base body, in particular at least in sections, is injected.
- the non-detachable connection between the base body and the functional body is thus produced by a plastic injection molding process.
- the base body can be inserted into an injection molding tool and either completely or partially encapsulated by the plastic material of the functional body.
- a particularly precise geometry of the hinge element or precise positioning of the functional body relative to the base body can be achieved.
- the position of the base body within the injection molding tool can be precisely defined by a corresponding holder, so that the molded functional body has a defined position with respect to the base body with high repetition accuracy.
- the functional body completely covers or covers the base body.
- the base body is thus completely enclosed by the functional body, in particular the base body has no exposed outer surfaces.
- the functional body covers or covers the base body only in sections.
- the base body thus has exposed outer surfaces on the one hand and surfaces covered by the functional body on the other hand.
- this embodiment enables more cost-effective production, since less plastic material is required to produce the functional body.
- the exposed outer surfaces can be used or designed for attachment to the body of the large household appliance.
- fastening openings for screws can be provided in the exposed outer surfaces of the base body, so that screws for fastening the hinge element to the body can contact the base body directly in order to enable direct force transmission.
- the functional body has at least one functional surface.
- the functional surface represents a surface that is or can be in contact with the closure element, in particular a surface that contributes or can contribute to positioning the closure element relative to the body and/or a surface that occurs when the closure element is pivoted serves or can serve as a guide surface relative to the body and/or a surface that directly contributes or can contribute to the transmission of force between the closure element and the body (ie at least contacts the closure element or the body).
- two, three or more functional surfaces are formed by one and the same functional body, they can be designed to be connected or separate from one another.
- the formation of more than one functional surface on one and the same functional body means that the functional body can be made more solid.
- the individual functional surfaces can thus be made larger, so that their respective surface pressures are reduced when a force is applied. Overall, higher forces can therefore act on the functional surfaces.
- the functional surface forms a sliding surface and/or a stop surface and/or a guide surface.
- the sliding surface interacts in particular with a further sliding surface which is formed on the closure element.
- the sliding surface can be formed, for example, by an outer lateral surface of a bearing pin formed by the functional body.
- the sliding surface can be formed by an annular surface, in particular an annular surface adjoining said outer lateral surface and extending radially outward from it.
- the stop surface can in particular be formed by a surface oriented parallel to a pivot axis and/or a flat surface and can serve to limit a maximum opening angle of the closure element.
- a further stop surface is provided on the closure element, which contacts the stop surface of the functional body at the maximum opening angle.
- the guide surface can in particular interact with a further guide surface formed on the closure element, in order to promote automatic closing of the closure element from a minimum opening angle.
- the further guide surface can be formed on a spring arm of a closing element, with the closing element being arranged on the closing element.
- the guide surface can be formed parallel to the pivot axis.
- the functional body forms a bearing bolt and/or a door stop and/or a door closer.
- the bearing bolt can be formed entirely and/or exclusively by the functional body.
- the bearing bolt can interact with a bearing bush, which is in particular formed entirely and/or exclusively on the closure element.
- no further components are required for the rotatable mounting of the closure element with respect to the body.
- the bearing bolt dips into the bearing bush.
- the bearing bush can, for example, be formed on an end strip of the closure element, in particular in one piece, for example by means of a blind hole.
- the bearing bolt preferably has an annular outer surface as a functional surface (sliding surface).
- the bearing pin is solid, for example in the form of a solid cylinder. According to one embodiment, however, it is provided that the bearing pin is essentially or completely formed by a hollow cylinder, reinforcement ribs preferably being formed on an inner lateral surface of the hollow cylinder. In this way, the use of materials can be further reduced. In addition, there is a lower risk of sink marks due to accumulations of material, particularly when the functional body is produced by a plastic injection molding process. A more uniform functional surface on the outer lateral surface of the bearing bolt can thus be generated.
- the door stop can be formed by an accumulation of material of the functional body.
- the door stop preferably forms a flat surface, which can be oriented in particular parallel to the pivot axis.
- the door stop interacts with a stop body, which is arranged on the closure element, at a maximum opening angle and thus limits the maximum opening angle of the closure element.
- the stop body can also be designed in one piece on an end strip of the closure element or be attached to it.
- the door closer can also be formed by an accumulation of material of the functional body, for example form a door-closing cam. In particular, the door closer can form a curved functional surface.
- the door closer interacts in particular with a spring element which is formed on the closure element or is attached to the closure element, in which it engages with the spring element at a minimum opening angle of the closure element Spring element arrives. In the process, closing forces acting on the closure element are generated.
- the functional body is molded onto the base body by an injection molding process, a sufficiently large accumulation of material can be produced, in particular for the door stop and the door closer. Compared to conventional elements mounted as one or more separate components, a more stable and durable construction can be made possible.
- the base body has a reinforcing projection covered by the bearing bush and/or a door stop and/or the door closer.
- the base body has extensions that extend into the bearing bush and/or the door stop and/or the door closer and thus further increase their stability.
- the reinforcing projections or extensions are preferably completely covered or bordered by the functional body.
- these reinforcing projections can have geometries that can be optimally selected for increasing stability.
- an undercut can be formed on a reinforcement projection, which would remain as a free space during the assembly of a conventional, plugged-on functional body.
- the base body has an, in particular exposed, fastening section.
- the fastening section is designed for mounting the hinge element on the body of the large household appliance.
- the fastening section can have one, two or more fastening openings (for example unthreaded through-openings).
- the fastening section has a preferably planar contact surface which, when the hinge element is installed, rests flat against a surface, in particular an end face, of the body. It is conceivable that the entire attachment section is covered by the functional body. In this way, damage to the surface of the body by the functional body made of plastic can be avoided. It is also conceivable that the fastening section is designed to be completely or at least partially exposed.
- the corresponding portion of the attachment portion is not covered by the functional body, but is an outer surface.
- direct force transmission can take place between a fastening element, for example a screw, and the fastening section.
- the fastening section has exposed fastening openings but has a contact surface covered by the functional body.
- the base body has a different material or consists of a different material than the functional body.
- the base body has a material with a higher strength or consists of a material with a higher strength than the functional body.
- the material of the base body could be a plastic with a higher strength than the plastic of the functional body.
- the base body has metal or consists of metal. In this way, the base body can reliably absorb the forces that typically act on the hinge element in large household appliances, even over a long period of use.
- the base body is designed in one piece.
- the base body is thus made from a single component. If the base body is made of metal, the base body can in particular be a stamped and bent component or a metal injection molded component.
- the material used for the functional body can be selected with regard to the functions it provides. According to one embodiment, it is provided that the functional body has PA6 or POM or consists of PA6 or POM. These plastics have good sliding properties.
- the functional body is designed in one piece.
- the functional body is thus made from a single component (for example injection molding).
- the functional body can be made of one material, ie it can have a homogeneous material structure.
- a further functional body comprising plastic is permanently fastened to the base body or is permanently connected to it.
- the functional body and the further functional body can in particular be spaced apart from one another, i.e. in particular be designed separately from one another and have no direct contact with one another.
- the non-detachable connection of the two functional bodies to the base body is based on different types of connection or the same type of connection is present.
- the functional body and the additional functional body are molded onto the base body. The features described in relation to the functional body according to the invention can also be applied to the further functional body.
- an additional functional element is fastened to the hinge element by means of a positive and/or non-positive connection, in particular is detachably fastened.
- the additional functional element can form a door stop or a door closer, for example.
- a large household appliance comprises a body in which a receiving space (for refrigerated goods) is formed, a closure element with which the receiving space of the body can be closed, and a hinge element according to the invention with which the closure element is hinged to the body.

- the base body 20 of the hinge element 9 is formed into the illustrated shape in the first manufacturing step.
- the first manufacturing step can include non-cutting machining (e.g. bending) to produce e.g. the bearing arm 23 or the reinforcing projections 47, 48, machining (e.g. drilling) to produce the fastening openings 25 or machining (e.g. stamping) to produce the outer ones include shape.
- the functional body 21 is attached to the base body 20 by means of the non-detachable connection.
- the base body 20 was placed in an injection molding tool in such a way that only the covering section 46 is overmoulded with the plastic material of the functional body 21 and the functional body 21 is formed as a result.
- both reinforcing projections 47, 48 can be formed from a single metal blank.

- This reinforcing projection 51 which is used at the same time to reinforce the two bearing bolts 28, 29, can thus be dimensioned wider (the width is measured in a plane perpendicular to the pivot axis 7). Admittedly, compared to the first exemplary embodiment according to FIG. 5, a higher use of material is required. However, the stability of the bearing element 9 can be increased again.
- the functional body 21 not shown in FIGS. 6 and 7 can in particular correspond to the functional body 21 of the first exemplary embodiment according to FIGS. 2 to 4.
