Abstract
Description
Technical Field
[0001] The present invention relates to a hinge element for large household appliances, comprising a base and a functional body made of plastic material. Background Technology
[0002] Large household appliances typically have a receiving space arranged within a housing and a door arranged on the housing for opening or closing the receiving space. Examples of this type of large household appliance are refrigeration appliances (refrigerators, freezers, horizontal freezers, wine cabinets, refrigerator combinations), dishwashers, cooking appliances, or washing machines. It is known that doors are rotatably mounted using hinge elements having a base typically fixed to the housing. Such hinge elements are known to include a functional body made of plastic material. This functional body typically forms a support pin, which is received into a corresponding support bushing of the door.
[0003] EP2281095A1 discloses a hinge element for a door of a household appliance, wherein the hinge element has a mounting section for mounting on a housing of the household appliance, a support arm extending from the mounting section, and a support element disposed on the free end of the support arm, wherein at least one of the two support screws of the hinge element is received in a support pin made of plastic material in an anti-torsion manner, the support pin being mounted in a support structure fixed to the door. Summary of the Invention
[0004] The object of this invention is to provide a hinge element that has better precision than known hinge elements, while still being easy and inexpensive to manufacture. Another object of this invention is to provide a large household appliance that provides a more precise connection between the door and the housing compared to known large household appliances, and which can be easily and inexpensively manufactured in the process.
[0005] This objective was achieved in accordance with the independent claims.
[0006] This invention is based on a hinge element for large household appliances, specifically a large household appliance hinge element. This type of hinge element is characterized by its ability to withstand strong forces over a long service life, both due to its size design and the materials used. Therefore, this type of hinge element must withstand the weight of a closing element of up to 70 kg during 200,000 opening and closing cycles without significantly negatively impacting its function.
[0007] Hinges are used here to connect, i.e., to rotatably secure, the closing element of a large household appliance to the appliance's housing. The closing element may in particular be a door or baffle, which is arranged on the outside of the housing to close off receiving spaces (e.g., spaces for food).
[0008] A hinge element comprises both a base and a functional element. The base, particularly implemented as an inherently rigid member, preferably forms the main element of the hinge element and serves to safely and reliably transmit forces acting on the hinge element (especially in cases of deformation of the hinge element without negatively impacting its function) between the closing element and the housing. In contrast, the functional element represents an additional component of the hinge element that performs at least one required function of the hinge element (e.g., providing a sliding surface, providing a supporting surface, providing a stop). The base and functional element may be made of different materials or be manufactured from different materials.
[0009] According to the invention, a non-removable connection is further provided between the substrate and the functional body. A non-removable connection is understood herein as a connection in which the substrate and the functional body can no longer be disassembled, separated, or detached from each other unless the substrate and / or the functional body and / or the connecting agent (e.g., adhesive) located therebetween are destroyed. Therefore, this non-removable connection forms a non-destructive non-removable or non-destructive removable connection.
[0010] This invention is based on the knowledge that a non-removable connection method makes it possible to position the functional element relative to the substrate with very high precision. Therefore, during the manufacturing process of the support element, the distance or angle between specific points or surfaces located on both the substrate and the functional element can be fixed or precisely defined. Thus, for example, by precisely determining the distance or angle between the contact surface on the substrate used to bring the support element and the housing into contact and the functional surface on the functional element used to provide a sliding surface, a support element with very precise operation can be provided.
[0011] Furthermore, this non-removable connection ensures that this high precision is maintained even during prolonged use. Unlike known support elements, which have individual support pins attached to bolts on the base, this non-removable connection prevents even minimal movement between the base and the functional unit during operation. Wear in the connection area between the base and the functional unit is prevented. If the functional unit forms a support pin, it can also, for example, prevent unwanted rotation of the support pin relative to the base.
[0012] Furthermore, the use of the hinge element of this invention simplifies the production of large household appliances because the hinge element, as a single component, is easier to handle or assemble. Since attaching the individual functional element is not required as an additional work step, the risk of incorrectly connecting the base and the functional element is eliminated. The non-removable connection also eliminates the possibility of accidentally releasing the functional element from the base during the manufacture of large household appliances.
[0013] When the doorstop is replaced at a later time, especially by the end consumer, the hinge element detaches from the housing and must be reattached to the other side of the housing during this process, thus eliminating the risk of the functional component accidentally detaching from the base. Therefore, there is no possibility of mistakenly reattaching the detached functional component to the base.
[0014] Embodiments of the present invention are specifically described in the dependent claims.
[0015] The non-removable connection between the substrate and the functional body can be achieved through methods such as material bonding between the substrate and the functional body. Therefore, according to one embodiment, the substrate and the functional body can be configured to be glued together. For example, spray adhesive or liquid adhesive can be used as the adhesive. It is conceivable that a functional body with a plastic material can be directly glued to or bonded to a substrate, such as a metal one. Similarly, it is conceivable that the functional body is formed from two pre-assembled components, which are implemented independently of each other and both have a plastic material, and they are directly glued together (e.g., an upper half and a lower half as two pre-assembled components). Combinations of these two variations are also conceivable.
[0016] According to one embodiment, the functional body is configured to be formed by a coating of the substrate. In particular, if the functional body is implemented as a support pin, the coating may be formed by a sliding layer. The coating may be, for example, sprayed and / or have a layer thickness of less than 1 mm.
[0017] Similarly, it is conceivable that the non-detachable connection between the substrate and the functional body is achieved through the shape-fit connection between the substrate and the functional body.
[0018] According to one embodiment, the functional body is configured to be formed, particularly at least partially formed, by overmolding a substrate, or the functional body is configured to be molded, particularly at least partially molded, on the substrate. Therefore, the non-removable connection between the substrate and the functional body is produced by a plastic injection molding method. Here, the substrate can be inserted into an injection molding tool and fully or partially injection molded from the plastic material of the functional body. In this way, particularly precise geometry of the hinge element or precise positioning of the functional body relative to the substrate can be achieved. Here, the position of the substrate in the injection molding tool can be accurately fixed by a corresponding support, so that the molded functional body has a defined position relative to the substrate and high repeatability.
[0019] According to one embodiment, the functional body is configured to completely cover or enclose the substrate. Therefore, the substrate is completely surrounded by the functional body, specifically, no external surfaces of the substrate are exposed.
[0020] According to an alternative embodiment, the functional body is configured to cover or enclose only a portion of the substrate. Thus, the substrate has an exposed outer surface on one hand and a surface covered by the functional body on the other. This embodiment makes manufacturing more cost-effective than having the functional body completely cover or enclose the substrate, as less plastic material is required to manufacture the functional body. Furthermore, the exposed outer surface can be used or implemented for attachment to the housing of large household appliances. Therefore, the exposed outer surface of the substrate can provide fastening openings for screws to secure hinge elements to the housing, allowing the screws to directly contact the substrate for direct force transmission.
[0021] According to one embodiment, the functional body is configured to have at least one functional surface. This functional surface refers to a surface that contacts the closure element, particularly a surface that helps or may help position the closure element relative to the housing, and / or a surface that serves or may serve as a guiding surface when the closure element rotates relative to the housing, and / or a surface that helps or may directly help transmit forces between the closure element and the housing (i.e., at least in contact with the closure element or the housing). If two, three, or more functional surfaces are formed by an identical functional body, these functional surfaces can be implemented together or separately from each other. Implementing more than one functional surface on an identical functional body allows the functional body to be implemented more firmly. Therefore, each functional surface can be implemented larger to reduce their respective surface pressures when subjected to force. In general, a larger force can therefore be applied to the functional surfaces.
[0022] According to one embodiment, the functional surface is configured to form a sliding surface and / or a stop surface and / or a guide surface. The sliding surface interacts, in particular, with another sliding surface implemented on the closing element during movement of the closing element. This sliding surface may be formed, for example, by the outer lateral region of a support pin formed by the functional body. Alternatively or additionally, the sliding surface may be formed by an annular surface, particularly an annular surface adjacent to and extending radially outward from the outer region. The stop surface may be formed, in particular, by a surface parallel to the pivot and / or is flat, serving to limit the maximum opening angle of the closing element. For this purpose, another stop surface is provided on the closing element, which contacts the stop surface of the functional body when the opening angle reaches its maximum. The guide surface may interact, in particular, with another guide surface on the closing element to facilitate automatic closing of the closing element from its minimum opening angle. For this purpose, the other guide surface may be implemented on a spring arm of the closing element, wherein the spring arm is arranged on the closing element. The guide surface may be parallel to the pivot. Because the functional body has a precise arrangement relative to the base, the closing element can be precisely guided during movement to achieve precise end stop at a predetermined maximum door opening angle, and the closing element can be reliably closed from the minimum door opening angle.
[0023] According to one embodiment, the functional body is configured to form a support pin and / or a door stop and / or a door closer. The support pin can be formed entirely and / or solely by the functional body. The support pin can interact with a support bushing, which is implemented entirely and / or solely on the closure element. In particular, the rotatable mounting of the closure element relative to the housing does not require other components. For hinge elements installed in large household appliances, the support pin is submerged in the support bushing. The support bushing can be implemented, for example, on the closure strip of the closure element, particularly as an integral part, for example, through a blind hole. The support pin preferably has an annular outer region as a functional surface (sliding surface). However, it is conceivable that the support pin is solid, for example, in the form of a solid cylinder. According to one embodiment, the support pin is formed substantially or entirely of a hollow cylinder, wherein the reinforcing ribs are preferably formed internally in their internal lateral regions. This further reduces material usage. Furthermore, the risk of sinking due to material buildup is lower during the manufacturing of the functional body by plastic injection molding. Therefore, a more uniform functional surface can be produced in the outer region of the support pin. The door stop can be formed by the accumulation of material from the functional body. The door stop is preferably formed as a plane, particularly oriented as a plane parallel to the pivot. At the maximum opening angle, the door stop interacts with a stop arranged on the closing element, thereby limiting the maximum opening angle of the closing element. The stop can also be integrally implemented on the closing strip of the closing element, or fixed thereto. The door closer can also be formed by the accumulation of material from the functional body, for example, forming a closing cam. The door closer can particularly be implemented as a curved functional surface. The door closer interacts particularly with a spring element implemented on or fixed to the closing element, which engages with the closing element at its minimum opening angle. A closing force is generated in this process acting on the closing element. If the functional body is injected into the matrix by injection molding, a sufficiently large material accumulation can be produced, particularly for door stops and door closers. This results in a more stable and durable structure compared to conventional elements installed as one or more independent components.
[0024] According to one embodiment, the substrate is configured to have reinforcing protrusions covered by support bushings and / or doorstops and / or door closers. The substrate, in particular, has protrusions extending into the support bushings and / or doorstops and / or door closers, thereby further increasing its stability. The reinforcing protrusions or extensions are preferably completely covered by or included therein by the functional body. In particular, if the functional body is molded onto the substrate by injection molding, these reinforcing protrusions can have a geometry optimally selected to increase stability. Thus, for example, cutouts can be made in the reinforcing protrusions, which would remain free space during conventional, connected assembly of the functional body. However, within the scope of the injection molding method, the cutouts can also be closed by the functional body, thereby further increasing the strength of the hinge element.
[0025] According to one embodiment, the base is configured to have a particularly exposed fastening section. The fastening section is used to assemble hinge elements onto the housing of a large household appliance. Here, the fastening section may have one, two, or more fastening openings (e.g., unthreaded openings). The fastening section has a contact surface that is preferably planar, which rests planarly against the surface of the housing, particularly the end face, when the hinge element is assembled. It is conceivable that the entire fastening section is covered by a functional body. This makes it possible to avoid damaging the surface of the housing by using a functional body made of plastic material. It is also conceivable that the fastening section is fully exposed or at least partially exposed. The exposed portion is understood here as the corresponding part of the fastening section not being covered by the functional body, but rather representing the external surface. In this way, direct force transmission can occur between the fastening element, such as a screw, and the fastening section. For example, it is conceivable that the fastening section has exposed fastening openings but also a contact surface covered by a functional body.
[0026] Preferably, the substrate is configured to have a different material than the functional body or be composed of a different material. In particular, the substrate is configured to have higher stiffness than the functional body or be composed of a material with higher stiffness. Thus, the substrate material can be a plastic with higher stiffness compared to the plastic material of the functional body. However, according to one embodiment, the substrate may include or be composed of metal. In this way, typically in the case of large household appliances, the substrate can withstand the forces acting on the hinge element during long-term use.
[0027] According to one embodiment, the substrate is configured as a single-piece structure. Therefore, the substrate is manufactured from a single component. If the substrate is made of metal, it can in particular be a stamped or bent component or a metal injection-molded component.
[0028] The materials used for the functional body can be selected based on the function it provides. Therefore, according to one embodiment, the material of the functional body includes PA6 or POM, or is composed of PA6 or POM. These plastics have good sliding properties.
[0029] According to one embodiment, the functional body is configured as a single unit. Therefore, the functional body is manufactured from a single component (e.g., injection molding). In particular, the functional body can be implemented using a single material, i.e., a material with a homogeneous material structure.
[0030] Essentially, one can imagine that a single, adhesive functional element is fixed to the substrate in a non-removable manner. All functional surfaces of the functional element are implemented on the single functional element.
[0031] Similarly, it is conceivable that functional bodies made of other plastic materials can be non-removably fixed to or non-removably connected to the substrate. Functional bodies and other functional bodies can be implemented particularly far apart from each other, i.e., separately, and without direct contact. It is conceivable that the inseparable connection between two functional bodies and the substrate is based on different or the same connection type. For example, it is conceivable that functional bodies and other functional bodies are injection molded onto the substrate. The features described for the functional bodies of the present invention can also be applied to other functional bodies.
[0032] Similarly, in addition to functional elements that are non-detachably connected to the base, additional functional components can be fixed to the hinge element, particularly non-detachably, through form-fitting and / or force-fitting. For example, additional functional components can form doorstops or door closers.
[0033] The large household appliance of the present invention includes a housing, wherein: a receiving space (for storing items to be cooled); a closing element by which the receiving space of the housing can be closed; and a hinge element as described in the present invention by which the closing element can be attached to the housing in a hinged manner.

[0043] Figure 1 A large household appliance 1, in the form of a refrigerator-freezer combination, is shown. The appliance 1 includes a housing 2 having a first receiving space 3 and a second receiving space 4 for receiving items to be refrigerated. These two receiving spaces 3 and 4 can be closed by two independent closing elements 5 and 6. The closing elements 5 and 6 are formed by doors rotatably mounted about a vertical pivot 7. Each closing element 5 and 6 is connected to the housing by two vertically spaced hinge elements. Thus, the first closing element 5 is attached to the housing 2 via an upper hinge element 8 and a middle hinge element 9. The second closing element 6 is attached to the housing via a middle hinge element 9 and a lower hinge element 10. The hinge elements 8, 9, and 10 are fixed to an end face 11 of the housing 2. The hinge elements 8, 9, and 10 have support pins that engage with corresponding support bushings of the closing elements 5 and 6. The upper hinge element 8 has a downwardly oriented support pin, and the lower hinge element 10 has an upwardly oriented support pin. The central hinge element 9 has an upwardly oriented support pin (for engaging with the support bushing of the first closing element 5) and a downwardly oriented support pin (for engaging with the second closing element 6). Closing elements 5 and 6 each have outer walls 12 and 13 and inner walls 14 and 15, which define cavities filled with insulating material. These cavities are closed by closing strips 16, 17, 18, and 19 at the upper or lower edge sections of closing elements 5 and 6. In the closing strips 16-19, which are formed of plastic, the support bushing is integrally implemented as a blind hole. The support pins of hinge elements 8, 9, and 10 engage directly with the support bushings without the need for other elements or components.
[0044] Figure 2 and Figure 3 The central hinge element 9 is shown from different angles. The hinge element 9 consists only of a base 20 and a functional body 21, which is non-removably fixed to the base. In this exemplary embodiment, the functional body 21 is injection molded onto the base 20.
[0045] The metal substrate 20 includes a fastening section 22 and a support arm 23. The support arm 23 extends approximately perpendicularly to the main extending plane of the fastening section 22 and protrudes forward (opposite to the depth direction y) relative to the end face 11. The fastening section 22 is configured for fastening to the housing 2, and thus has a planar contact surface 24 on one side and two fastening openings 25 on the other. The contact surface 24 faces away from the support arm 23. The support arm 23 has a first end 26 through which the support arm is connected to the fastening section 22. The substrate 20 has a reinforcing structure 27 formed in a rounded edge shape. This structure extends from the fastening section 22, beyond the first end 26, and into the support arm 23. The rounded edge 27 terminates before the functional body 21 opposite to the depth direction Y.
[0046] The functional body 21, composed entirely of plastic, has two support pins 28 and 29. The two support pins 28 and 29 extend vertically in opposite directions along the height axis Z, starting from the central section 30. The upper support pin 28 engages with the support bushing of the lower door closure strip 17 of the first closure element 5. The lower support pin 29 engages with the support bushing of the upper door closure strip 18 of the second closure element 6. Both support pins 28 and 29 have a cylindrical design including an annular outer region. The outer region forms functional surfaces 31 and 32, which serve as sliding surfaces engaging with the annular inner region of the support bushing. The two support pins 28 and 29 are at least partially (starting from their free ends) implemented as hollow cylinders. A reinforcing rib 33 is integrally formed within a cavity defined by its inner region. The reinforcing rib 33 extends from the inner region toward the center, i.e., toward the pivot 7. Annular end faces 34 and 35 are present at the free ends of the support pins 28 and 29. End faces 34 and 35 are located in a horizontal plane (including the plane in the width direction x and depth direction y). The reinforcing rib 33 is retracted or concave relative to end faces 34 and 35 so as not to create any interfering profile for the support bushings of the closing elements 5 and 6.
[0047] The functional body 21 also includes a door closer 36. The door closer 36 has a curved functional surface 37, which is configured to be parallel to the pivot 7. The door closer 36 is formed by a buildup of material from the functional body 21, particularly in the form of a closing cam, and can interact with a spring element, which is specifically implemented or arranged on the closing bar 18 of the closing element 6. The door closer 36 is arranged on the central section 30.
[0048] Functional body 21 also has a door stop 38, which is configured to have a planar functional surface 39 aligned parallel to pivot 7. Functional surface 39 is also arranged on central section 30 and is substantially opposite door closer 36 relative to pivot 7.
[0049] The central section 30 of functional body 21 has two annular shoulders 40, 41. Shoulders 40, 41 are directly adjacent to the support pins 28, 29 in the axial direction and therefore face the free ends of the support pins 28, 29. Shoulders 40, 41 form guide surfaces 42, 43, which represent annular sliding surfaces. Recesses 44 to prevent excessive material buildup in functional body 21 are implemented in the shoulders 40, 41, thereby ensuring high precision of their functional surfaces 31, 37, 42, 43.
[0050] Figure 4 It is the hinge element 9 along Figure 2 A cross-sectional view along line IV-IV. The support arm 23 has a second end 45, which is opposite to the first end 26 and serves as a free end. In the depth direction y, the second end 45 is completely covered by the functional body 21 along the coverage section 46. The functional body 21 here completely surrounds the base 20 as an injection-molded element. Specifically, the functional body 21 has no air-filled closed cavity, or there is no air-filled closed cavity between the base 20 and the functional body 21.
[0051] Especially according to Figure 5 As can be seen, the support arm 23 has two reinforcing protrusions 47 and 48. The reinforcing protrusions 47 and 48 are substantially perpendicular to the support arm 23 and therefore substantially parallel to the pivot 7. The reinforcing protrusions 47 and 48 are formed by pins with rectangular cross-sectional profiles and extend approximately 50% of the longitudinal extension distance of the support pins 28 and 29 in the direction toward the end faces 34 and 35.
[0052] Figure 5 It shows Figures 2 to 4 The base 20 of the hinge element 9 of the invention. The stamped and bent portion shown is the result of a first manufacturing step of the hinge element 9. Based on a planar metal blank extending in a plane, this base 20 is shaped into the shape of the first manufacturing step. The first manufacturing step may in particular include non-cutting processes (e.g., bending) for generating, for example, support arms 23 or reinforcing protrusions 47, 48, processes (e.g., drilling) for generating fastening openings 25, or processes (e.g., stamping) for generating the external shape. In a subsequent second manufacturing step of the hinge element 9, the functional body 21 is connected to the base 20 by a non-removable connection. In this exemplary embodiment, the base 20 has been placed in an injection molding tool such that only the covering section 46 is covered by the injection-molded plastic material of the functional body 21, ultimately resulting in the functional body 21.
[0053] Since the exact location of the reinforcing protrusions 47 and 48 has only a small impact on improving the stability of the support pins 28 and 29, the reinforcing protrusions 47 and 48 are eccentrically arranged relative to the pivot 7 in all cases. Thus, both reinforcing protrusions 47 and 48 can be formed from a single metal blank.
[0054] The base 20 has two additional reinforcing protrusions 49, 50, which are implemented in the area of the door closer 36 or the door stop 38.
[0055] Figure 6 and Figure 7 The base 20 of the hinge element according to a second exemplary embodiment of the invention is shown from two different angles. The base 20 is also a metal stamped and bent component. The fastening section 22 substantially corresponds to the fastening section 22 of the first exemplary embodiment. The support arm 23 also has a rounded edge 27.
[0056] The second end 45 of the support arm 23 represents the same as the first exemplary embodiment (see reference). Figure 5 The significant difference is that the two reinforcing protrusions 49, 50 are also integrally mounted here to reinforce the door closer 36 or door stop 38 formed by the functional body (not shown). However, any reinforcing body 51 used to reinforce the support pins 28, 29 is formed by a single web. The web here extends from the main extension plane of the second end 45, first perpendicularly, particularly vertically, along a first direction (especially in the height direction z), and then from the fold 52 along a second direction opposite to the first direction (especially opposite to the height direction z). Therefore, this reinforcing protrusion 51 simultaneously reinforces both support pins 28, 29, and thus its width can be measured to be wider (here, the width is measured in a plane perpendicular to the pivot 7). However, compared with according to Figure 5 Compared to the first exemplary embodiment, this requires the use of a large amount of material. However, the stability of the support element 9 can be further improved.
[0057] Figure 6 and Figure 7 Functional body 21, not shown in the figure, may specifically correspond to according to Figures 2 to 4 Functional body 21 of the first exemplary embodiment. The dashed line here represents the boundary of the section (covered section 46) that is covered or molded by functional body 21 in the depth direction y, starting from the second end 45.
