Description

The present invention relates to a hinge, in particular for a household appliance, according to the preamble of claim 1.

Such a hinge, in particular for a household appliance, for example, is already the EP 2 759 669 A2 to be known as known. The hinge comprises a first hinge part, which is formed for example as a housing of the hinge. Furthermore, the hinge comprises a second hinge part, which is held pivotably on the first hinge part. The second hinge part is, for example, a swivel arm, which can be connected to a door of the household appliance, for example. Furthermore, the first hinge part can be fastened, for example, to a device housing of the household appliance, so that in the completely produced state of the household appliance, the door is held pivotably on the appliance housing via the hinge. As a result, the door can be pivoted relative to the device housing and thereby moved, for example, between a closed position and an open position.

The hinge further comprises a third hinge part provided in addition to the first hinge part and in addition to the second hinge part, which is coupled to the second hinge part and is displaceable relative to the first hinge part, that is translationally movable. Characterized in that the third hinge part is coupled to the second hinge part, the third hinge part is with the second Hinge part mitbewegbar. In other words, when the second hinge part is pivoted relative to the first hinge part, as a result of the coupling of the second hinge part with the third hinge part, the third hinge part is displaced relative to the first hinge part, that is moved translationally.

The third hinge part is usually referred to as a car. Furthermore, the EP 1 199 433 A2 a hinge for furniture, comprising a hinge arm connected to a door-side hinge part, and a fluid damper having a housing and an operating part. It is envisaged that the housing of the fluid damper is placed on the outside of the hinge arm and that the actuating part engages the door or the door-side hinge part.

The WO 2012/168748 A1 discloses a hinge according to the preamble of claim 1. The EP 1 995 524 A2 discloses a hinge for wings or doors, in particular of household electrical appliances.

Furthermore, the EP 3 073 038 A1 to take a hinge for doors of household electrical appliances as known.

Object of the present invention is to develop a hinge of the type mentioned in such a way that a particularly advantageous function of the hinge in a particularly simple manner and can be realized as needed.

This object is achieved by a hinge having the features of patent claim 1. Advantageous embodiments with expedient developments of the invention are specified in the remaining claims.

A first, not according to the invention aspect relates to a damper module for a first hinge part, a second hinge part pivotably held on the first hinge part and a hinge part coupled to the second hinge part and accommodated at least partially in the first hinge part and displaceable relative to the first hinge part having hinge, in particular for a household appliance. The damper module comprises a base element, which has at least one fastening element, by means of which the damper module, in particular reversibly detachable, can be fastened to the first hinge part. In other words, the damper module by means of the fastener and thus on the base member, in particular reversibly detachable, that is non-destructively detachable, fastened to the first hinge part. Under the reversibly releasable fastenability is to be understood that the damper module can be fastened by means of the fastener to the first hinge part and released again from the first hinge part, without causing damage or destruction of the first hinge part or the damper module.

The damper module further comprises at least one damper device at least indirectly retained on the base member for damping relative movement between the first hinge member and the second hinge member. By damping the relative movements, excessively fast relative movements between the first hinge part and the second hinge part can be avoided. Furthermore, it can be avoided that relative movements between the first hinge part and the second hinge part excessively rapid speed changes occur, so that it can be avoided, for example, that the relative movements between the first hinge part and the second hinge part ends excessively fast or excessively abrupt.

Furthermore, the damper module comprises at least one actuating element which can be moved relative to the base element and which is held, for example, at least indirectly movably on the base element relative to the base element. About the actuator for damping the relative movements between the first hinge part and the second hinge part, the damper device is actuated. By actuating the damper device, the relative movements between the first hinge part and the second hinge part can be damped, wherein the damper device can be actuated via the actuating element. In this case, the actuating element is designed to cooperate with the third hinge part for damping the relative movements in the installed position of the damper module, which occupies the installation position in the state fastened by means of the fastener on the first hinge part, in particular reversibly detachable.

In other words, the damper module assumes its installation position when the damper module is fastened to the first hinge part by means of the fastening element and thus via the base element, in particular reversibly detachable. In this installation position, the actuating element can interact with the third hinge part, in particular in such a way that the third hinge part can come into support contact with the actuating element in its translatory movements relative to the first hinge part. Since the third hinge part coupled to the second hinge part, in particular positively connected, is, the third hinge part with the second hinge part mitbewegbar. If the second hinge part is pivoted relative to the first hinge part, the third hinge part is thereby displaced by the second hinge part relative to the first hinge part, that is, moved translationally. Since in the installed position, the actuating element engages, for example, in the first hinge part or since the third hinge part protrudes, for example, from the first hinge part, the third hinge part acts in its translational movement relative to the first hinge part with the actuating element, whereby the actuating element of the third hinge part relative to the base element is moved. As a result, the damper device is actuated via the actuating element, so that the damper device interacts with the second hinge part via the third hinge part. As a result, the pivoting or the movement of the second hinge part is damped relative to the first hinge part by means of the damper device.

The damper module is designed as a module or module part, that is to say as an assembly, in particular an independent assembly. This means that the damper module per se or in itself forms an independent, coherent or assembled structural unit, which in particular is assembled or can be assembled independently of the hinge parts. The damper module can thus be assembled independently of the hinge parts and in particular pre-assembled and handled. Further, since the damper module is fastened to the first hinge part in a non-destructively releasable manner by means of the fastening element and thus connected to the first hinge part and released again from the first hinge part, without damaging or damaging it the first hinge part or the damper module comes, the first hinge part or the hinge parts can be equipped in a particularly simple manner and as needed with the damper module. The damper module in this case has at least one function, which consists in damping relative movements between the first hinge part and the second hinge part, in particular by the intermediary of the third hinge part. The hinge parts or the hinge as a whole can therefore be equipped as needed with the damper module and thus be extended in a particularly simple and cost-effective manner to the said function of the damper module.

If, for example, initially a first construction variant of the domestic appliance is provided, wherein in this first construction variant no damping of the relative movements between the first hinge part and the second hinge part is provided, then the damper module is not used in the first construction variant. In other words, the damper module is simply omitted in the first construction variant, so that in the first construction variant, although the hinge parts, but not the damper module is used.

Since the damper module by means of the fastener or by means of the base member can be connected non-destructively releasably connected to the first hinge part, so that the hinge in the manner described particularly simple to the said function of the damper module can be added, the first construction variant in a particularly simple and cost-effective manner a second construction variant be developed or supplemented, wherein in this second construction variant, a damping of the relative movements between the first hinge part and the second hinge part is provided. In the second construction variant, the damper module is used in order to dampen the relative movements between the first hinge part and the second hinge part by means of the damper module, in particular by means of the damper device of the damper module.

To further develop the first construction variant for the second construction variant, the damper module is connected in a simple manner via the fastening element to the first hinge part, so that the hinge is supplemented by the previously described function of the damper module. This way it is on especially easy and cost-effective way possible to realize different functions of the hinge as a whole and to represent the different construction variants. In particular, it is possible to further develop the first construction variant according to its needs to the second construction variant by supplementing it with the damper module after the first construction variant has been produced. Thus, for example, a person can first use the first construction variant. If, for example, this person decides, after a certain period of time, that damping of the relative movements between the first hinge part and the second hinge part is advantageous or if the person desires such damping, then the first design variant can be easily developed into the second construction variant by virtue of the Hinge is added to the damper module in a simple way. In this way, a particularly advantageous function of the hinge can be realized in a particularly simple manner and particularly needs-based.

Furthermore, it is also possible in a particularly simple manner to refine the second construction variant to the first construction variant. For this purpose, the damper module is simply detached and removed from the first hinge part in a non-destructive way, whereby the described function of the damper module is removed from the hinge as a whole.

As already indicated, the damper module is preferably used for household appliances. By means of the damper module can be realized in a particularly simple and cost-effective manner needs different construction variants of such a household appliance. Under a household appliance is a particular electrical device to understand, the household appliance is also referred to as a kitchen appliance, for example. For example, the household appliance has a device housing, by which at least one treatment chamber of the household appliance is formed. Furthermore, the household appliance has at least one door, which is also referred to as a flap or lid. In the fully manufactured state of the household appliance, the door is movable over at least one previously described hinge, in particular pivotally supported on the device housing, so that the door relative to the device housing between a closed position and at least one open position moves, in particular pivoted, can. In this case, for example, the first hinge part attached to the door and the second hinge part attached to the device housing or vice versa.

In the closed position, at least a portion of the treatment space is covered by the door and thus closed. In the open position, the door releases the subarea, so that, for example, objects and / or food can be arranged in the treatment room via the released subarea or removed from the treatment chamber. The treatment room is used, for example, for treating, in particular processing and / or processing, objects and / or foods arranged in the treatment room. The treatment room is, for example, a cooking space for cooking food. Furthermore, the treatment space may be a heating space for heating objects and / or foods arranged in the treatment space. The treatment room can also be a laundry room for washing and / or cleaning objects. Thus, the household appliance is designed for example as a stove, oven, microwave oven or dishwasher. Furthermore, it is conceivable that the treatment room is used for cooling objects and / or foods. Thus, the household appliance is designed for example as a refrigerator, freezer or freezer or the like home appliance.

The actuator is pivotally supported on the base member about a pivot axis relative to the base member. In other words, the actuating element is not or not only displaceable relative to the base element, but the actuating element is at least pivotable relative to the base element. As a result, leverage ratios can be adjusted particularly advantageously and as needed, so that the relative movements between the first hinge part and the second hinge part can be damped particularly well. By setting the lever ratios, it is to be understood, for example, that a first distance between the pivot axis of the actuating element and a first crosspoint and a second distance between the pivot axis of the actuating element and a second crosspoint can be adjusted as required.

It can be provided that the third hinge part protrudes from the first hinge part, so that the actuating element can cooperate in the installed position with the third hinge part.

However, it has proven to be particularly advantageous if the actuating element is designed to engage in the installation position of the damper module in the first hinge part and to cooperate with the third hinge part for damping the relative movements. Since in the installed position, the actuating element engages in the first hinge part, the third hinge part can cooperate with its translational movements relative to the first hinge part with the actuating element and come in particular in support system with the actuating element, so that the relative movements can be particularly well damped. Since the actuating element engages in the installed position in the first hinge part, it can be avoided that the third hinge part protrudes from the first hinge part, so that the space requirement of the hinge can be kept low.

In an advantageous embodiment, the actuating element projects beyond the base element along a support direction, along which the damper module is supported in its installed position on the first hinge part, towards the first hinge part. In order to attach the damper module to the first hinge part, the base element is arranged, for example, on the first hinge part and thereby supported in the support direction. In this support direction, the actuating element projects beyond the base element to the first hinge part, so that the actuating element engages in the support direction or along the support direction in the first hinge part. As a result, the third hinge part can cooperate particularly well with the actuating element, so that the damper device can be actuated via the actuating element during relative movements between the first hinge part and the second hinge part. As a result, the relative movements between the first hinge part and the second hinge part can be damped particularly well.

By damping the relative movements between the first hinge part and the second hinge part, for example, relative movements between the previously described door and the device housing of the household appliance described above can be damped, so that, for example, an excessively hard impact of the door against the device housing can be avoided.

At the first crosspoint, the actuator is, for example, hingedly connected to the damper device. At the second coupling point, the actuating element can cooperate, for example, with the third hinge part. By adjusting these distances as needed, for example, a translation, in particular a damper ratio can be realized, so that, for example, if the third hinge part moves at a first speed and / or a first path, then a movement of the damper device, in particular at least one damper part of Damper device, with a different from the first speed second speed and / or results in a relation to the first path different second path. In particular, it is possible by the setting of the lever ratios, even with only small ways by which the third hinge part is moved to realize high speeds with which the damper device is moved or actuated, thereby also at small distances of the third hinge part a high To realize damping force or a high damping effect, by means of which the relative movements between the first hinge part and the second hinge part can be attenuated. As a result, a particularly advantageous function of the damper module and thus of the hinge can be represented.

It has been found to be particularly advantageous if the pivot axis of the actuating element extends at least substantially perpendicular to the support direction.

In a further embodiment, the damper device comprises at least a first damper part, which is designed, for example, as a cylinder. Further, the damper device comprises, for example, a second damper part which is accommodated at least partially in the first damper part and which is displaceable relative to the first damper part and which is designed, for example, as a piston. In this case, the actuating element is pivotally coupled to one of the damper parts. As a result, for example, forces acting on the actuating element from the third hinge part can be transferred to the damper device in a particularly advantageous manner, so that the relative movements between the first hinge part and the second hinge part can be damped particularly well. Furthermore, this can be a Verharken or Tilting the damper parts can be avoided, so that there is a defined and clean running of the second damper part in the first damper part. As a result, unwanted, caused by the damper module impairments of the pivoting of the second hinge part relative to the first hinge part can be avoided, so that, for example, the aforementioned door of the household appliance can be easily moved, for example by a person even when using the damper module.

It has proven to be particularly advantageous if the second damper part is movable relative to the first damper part by means of the actuating element. In this case, the actuating element is preferably connected positively and / or non-positively with the second damper part.

A further embodiment is characterized in that the correspondingly different damper part is supported, in particular held, in an articulated manner on the base element. In other words, it is preferably provided that the actuating element with the one damper part is in particular hingedly coupled, wherein the other damper part hinged to the base member, in particular held, is. As a result, a particularly advantageous function of the damper module and thus of the hinge as a whole can be realized.

In order to realize a particularly advantageous function of the damper module and thus of the hinge as a whole, it is provided in a further embodiment that the damper module comprises at least one second actuating element, which is held pivotably on the base element about a pivot axis relative to the base element, via which damper device for damping the relative movements is operable. In this case, the second actuating element is designed to cooperate with the third hinge part for damping the relative movements in the installation position of the damper module. Preferably, the second actuating element is designed to engage in the installation position of the damper module in the first hinge part and cooperate for damping the relative movements with the third hinge part.

Further, the aforementioned other damper part is pivotally coupled to the second actuator. The damper device is thus coupled, for example via one damper part articulated to the first actuating element and the other damper part articulated to the second actuating element, so that the damper device is held on the base member via the pivotally held on the base member actuating elements, in particular articulated.

As a result of this embodiment of the damper module, a bidirectional damping of the relative movements between the first hinge part and the second hinge part can be represented. In other words, if, for example, the second hinge part is pivoted in a first direction of rotation or pivoting relative to the first hinge part, this results, for example, in a displacement of the third hinge part relative to the first hinge part in a first direction. If, for example, the second hinge part is pivoted relative to the first hinge part in a second rotational or pivoting direction opposite to the first pivoting or rotating direction, this results, for example, in a displacement of the third hinge part relative to the first hinge part in a second direction opposite to the first direction , During the displacement of the third hinge part in the first direction, the third hinge part cooperates, for example, with the first actuating element, thereby damping the pivoting of the second hinge part in the first rotary or pivoting direction by means of the damper device. When the third hinge part is displaced in the second direction, the third hinge part cooperates, for example, with the second actuating element, whereby the pivoting of the second hinge part about the second rotary or pivoting direction is damped. As a result, for example, both an excessively hard opening and an excessively hard closing of the door of the household appliance can be avoided, so that a particularly advantageous function can be represented.

A particularly advantageous damping function can be realized in that the pivot axes of the actuating elements are parallel to each other. Preferably, the rotational pivot axes coincide so that the pivot axes are coaxial with each other. As a result, the space requirement of the damper module can be kept very low, which benefits its function.

Another embodiment is characterized in that the damper device is designed as a fluid damper. The relative movements between the first hinge part and the second hinge part can thus be damped with the aid of a fluid, in particular a liquid and / or a gas, so that a particularly advantageous damping effect can also be realized if the door has a high weight, for example.

Finally, it has proved to be advantageous in the first aspect, when the fastener is at least substantially hook-shaped and thereby formed to engage behind a wall portion of the first hinge part in the installed position, thereby the damper module, in particular reversibly releasably and, positively on the first Fasten hinge part. In particular, it is thus possible to lock the fastening element with the first hinge part, in particular with the wall region, so that the damper module can be reversibly detachably fastened to the first hinge part in a particularly simple and cost-effective manner and released again from the first hinge part.

A second aspect of the invention relates to a hinge, in particular for a household appliance. The hinge includes a first hinge part, a second hinge part pivotally attached to the first hinge part, and a third hinge part coupled to the second hinge part and slidable relative to the first hinge part. The first hinge part, for example, a housing of the hinge, wherein the third hinge part is at least partially disposed in the housing. For example, the third hinge part is mounted longitudinally displaceable on the first hinge part.

The second hinge part is for example a pivoting arm, which can be pivoted relative to the first hinge part. In finished manufactured state of the household appliance, for example, the first hinge part on the device housing and the second hinge part attached to the door or vice versa.

The third hinge part is, for example, a so-called car. Since the third hinge part is coupled to the second hinge part, in particular connected in a form-fitting manner, the third hinge part is connected to the second hinge part Hinge part mitbewegbar. In other words, if the second hinge part is pivoted relative to the first hinge part, this causes, for example, a displacement of the third hinge part relative to the first hinge part. In order to realize a particularly advantageous function of the hinge in a particularly simple manner and especially as required, the hinge comprises a damper module which has a base element which has at least one fastening element. By means of the fastening element, the damper module, in particular reversibly detachable, attached to the first hinge part. The damper module further has at least one damper device held at least indirectly on the base element for damping relative movements between the first and the second hinge part. Furthermore, the damper module has at least one actuating element which can be moved relative to the base element and via which the damper device can be actuated for damping the relative movements. In this case, the actuating element by means of the third hinge part is movable relative to the base element for damping the relative movements. Advantages and advantageous embodiments of the first aspect are to be regarded as advantages and advantageous embodiments of the second, inventive aspect and vice versa.

According to the invention, the actuating element is held pivotably on the base element about a pivot axis relative to the base element. In other words, the actuating element is not or not only displaceable relative to the base element, but the actuating element is at least pivotable relative to the base element. As a result, leverage ratios can be adjusted particularly advantageously and as needed, so that the relative movements between the first hinge part and the second hinge part can be damped particularly well. By setting the lever ratios, it is to be understood, for example, that a first distance between the pivot axis of the actuating element and a first crosspoint and a second distance between the pivot axis of the actuating element and a second crosspoint can be adjusted as required. The actuator is partially disposed outside of the hinge part, wherein the actuator engages the first hinge part and is movable relative to the base element for damping the relative movements by means of the third hinge part. The damper device has at least a first damper part and at least one at least partially received in the first damper part and displaceable relative to the first damper part second damper part, wherein the actuating element is pivotally coupled to one of the damper parts.

To realize a particularly advantageous function, it is provided in an advantageous embodiment of the invention that the second hinge part between at least a first position and at least one second position is pivotable relative to the first hinge part. The first position is, for example, the aforementioned closed position, wherein the second position is, for example, the aforementioned open position or vice versa. In this case, the mitbewegbare with the second hinge part third hinge part is spaced in at least one of the positions of the actuating element and comes when pivoting the second hinge part relative to the first hinge part of the at least one position in the other position in support system with the actuating element. In other words, if the second hinge part is pivoted relative to the first hinge part from the at least one position into the other position, the third hinge part thereby comes into support engagement with the actuating element.

As a result, the third hinge part moves the actuator relative to the base member. As a result, the actuating element actuates the damper device, which dampens the pivoting of the second hinge part as a result of their operation. This makes it possible to provide the first hinge part and thus the hinge as a whole in a simple manner and as needed with the damper module or to remove the damper module in a simple manner from the first hinge part, without this the actuator must be connected in a complicated manner with the third hinge part , To equip the hinge with the damper module, we connected the damper module in a simple manner with the first hinge part or attached to the first hinge part. As a result, the damper module is brought into its installation position, and further, the actuating element is inserted into the first hinge part. As a result, the third hinge part can come in support system with the actuator. An additional connection of the actuating element with the third hinge part is not provided and is not required.

Finally, it has proven to be particularly advantageous if the fastening element is positively connected to the first hinge part, so that the damper module is held in a form-fitting manner on the first hinge part. As a result, the damper module can be fastened to the first hinge part in a particularly simple manner and as required and released from the first hinge part. In particular, it is advantageously provided that the fastening element and thus the damper module are locked in total with the first hinge part. As a result, the damper module is firmly held on the first hinge part. Furthermore, the damper module can be easily removed again from the first hinge part.

Fig. 1 shows a generally designated 10 damper module according to a first embodiment according to the invention for a generally designated 12 hinge, which in this case comprises the damper module 10, that is equipped with the damper module 10. The hinge 12 comprises a first hinge part in the form of a housing 14. Further, the hinge 12 comprises a second hinge part in the form of a pivot arm 16 which is pivotally supported on the housing 14. This means that the pivot arm 16 is held on the housing 14 about a pivot axis 18 relative to the housing 14 pivotally. For this purpose, the hinge 12 comprises a bolt 20, which engages in each case in the housing 14 and in the pivot arm 16, so that the pivot arm 16 is pivotally connected by means of the bolt 20 with the housing 14.

The hinge 12 is used for a household appliance, which in its completely manufactured state has a device housing, by which at least one treatment space is formed. Furthermore, the household appliance in its completely manufactured state comprises at least one door, which is held pivotably on the housing via the hinge 12. In this case, for example, the housing 14 is fixed to the device housing, wherein the pivot arm 16 is attached to the door. In the fully manufactured state of the household appliance, the door is thus movable relative to the device housing between a closed position and at least one open position, in particular pivotable. The closed position corresponds, for example, with a first position of the pivot arm 16, wherein the open position corresponds, for example, with a second position of the pivot arm 16. Thus, the pivot arm 16 is pivotable relative to the housing 14 between the first position and the second position. In the closed position, at least a portion of the treatment space is covered by the door and thus closed. In the open position, the door releases the subarea, so that, for example, objects and / or food can be arranged in the treatment room via the released subarea or removed from the treatment chamber.

As will be explained in more detail below, the damper module 10 serves to dampen relative movements between the pivot arm 16 and the housing 14, whereby relative movements between the door and the device housing are damped. As a result, for example, an excessively hard impact of the door against the device housing can be avoided.

In Fig. 1 the housing 14 is shown transparent. The hinge 12 in this case comprises a third hinge part in the form of a so-called carriage 22. This means that the third hinge part is formed separately from the first hinge part and the second hinge part and is provided in addition to the first hinge part and in addition to the second hinge part. In this case, the carriage 22 is pivotally coupled to the pivot arm 16, so that the carriage 22 is mitbewegbar with the pivot arm 16. The carriage 22 is at least partially, in particular at least predominantly or completely, arranged in the housing 14 and relative to the housing 14 translationally movable, that is displaceable. In Fig. 1 illustrates a double arrow 24 a direction of movement along which the carriage 22 relative to the housing 14 slidably, that is translationally movable.

The carriage 22 is coupled to the pivot arm 16 such that a bolt 26 is provided which is partially disposed in the carriage 22 and partially on the pivot arm 16. This means that the bolt 26 engages in the carriage 22 and in the pivot arm 16. In the present case, the swivel arm 16 has a guide slot 28 into which the bolt 26 engages. If the pivot arm 16 is pivoted relative to the housing 14 about the pivot axis 18, so the carriage 22 is thereby displaced by means of the pivot arm 16 relative to the housing 14 along the direction of movement. For example, if the door is opened, that is moved from the closed position to the open position, the pivot arm 16 is moved from the first position to the second position. Here, the pivot arm 16 is relative to the image plane of Fig. 1 pivoted clockwise about the pivot axis 18 relative to the housing 14. Thereby, the carriage 22 via the pivot arm 16 relative to the housing 14 with respect to the image plane of Fig. 1 moved to the right.

If the door of the household appliance is closed, that is to say moved out of the open position into the closed position, then the pivot arm 16 is pivoted from the second position into the first position. In this case, the pivot arm 16 relative to the image planes of Fig. 1 pivoted counterclockwise relative to the housing 14. Thereby, the carriage 22 via the pivot arm 16 relative to the housing 14 with respect to the image planes of Fig. 1 moved to the left. Thus, the carriage 22 is moved with the pivot arm 16. In particular, it can be provided that the carriage 22 is mounted longitudinally displaceably on the housing 14.

The hinge 12 comprises a spring 30 designed, for example, as a helical spring, which on the one hand is connected to the carriage 22 and on the other hand is held on the housing 14. By moving the pivot arm 16 from the first position to the second position and thereby moving the carriage 22 relative to the housing 14, the spring 30 is tensioned so that the spring 30 provides a spring force which acts on the carriage 22 and over the carriage 22 acts on the pivot arm 16. This spring force causes, for example, a force acting about the pivot axis 18 Torque, which counteracts the opening of the door. Furthermore, the torque assists in closing the door. As a result, a particularly advantageous function of the hinge 12 can be displayed, so that the door is particularly easy to use, that is, can be moved.

In order to be able to realize a particularly advantageous function of the hinge 12 in a particularly simple manner and as required, the hinge 12 comprises the damper module 10. The damper module 10 is a module or a module part, which is designed as an assembly. In other words, the damper module 10 is an independent assembly or an independent structural unit which is assembled or preassembled independently of the hinge parts (housing 14, swivel arm 16 and carriage 22). In its assembled state, the damper module 10 can be reversibly detachably connected to the housing 14 and thus released again from the housing 14, without resulting in damage or destruction of the damper module 10 or the housing 14.

Fig. 1 shows a first embodiment of the damper module 10 and thus the hinge 12 in total. The damper module 10 includes a base member 32 which is formed, for example, as a plate. In the present case, the base element 32 is formed from a metallic material, in particular from a steel. In particular, it can be provided that the base element 32 is formed as a sheet metal component. Alternatively, it is conceivable that the base element 32 is formed from a plastic. Here, the base member 32 is formed, for example, as an injection molded part and thus produced by injection molding.

The base element 32 is preferably formed in one piece and has a plurality and in the present case, for example, two fastening elements 34, which in the present case are at least substantially hook-shaped. In other words, the fasteners 34 are formed as respective hooks. By means of the fastening elements 34, the damper module 10 is reversibly releasably fastened to the housing 14 or fastened. Thus, the damper module 10 can be attached as required to the housing 14 and from the housing 14 again be solved without causing damage or destruction of the damper module 10 or the housing 14.

The damper module 10 further comprises at least one damper device 36, which is held at least indirectly on the base element 32 and which is preferably designed as a fluid damper. By means of the damper device 36 relative movements between the pivot arm 16 and the housing 14 are damped. For this purpose, the damper module 10 further comprises at least one actuation element 38 movable relative to the base element 32. The actuation element 38 is held, for example, at least indirectly movably on the base element 32 relative to the base element 32. In this case, the actuating element 38 is designed to engage in the installed position of the damper module 10 in the housing 14 and to cooperate with the carriage 22 for damping the relative movements between the pivot arm 16 and the housing 14. The damper module 10 assumes its installation position by means of the fastening elements 34 on the housing 14 reversibly releasably secured state, which in Fig. 1 is shown. Thus shows Fig. 1 the installation position of the damper module 10. In this installation position, the actuating element 38 engages in the housing 14 a. In other words, the actuator 38 protrudes into the housing 14, so that the carriage 22 - when the carriage 22 is moved relative to the housing 14 - can cooperate with the actuator 38.

In the installed position, the damper module 10, in particular the base element 32, on the housing 14 along an in Fig. 1 supported by an arrow 40 support direction. In this case, the actuating element 38 projects beyond the base element 32 along or in the support direction toward the housing 14. For this purpose, the actuating element 38 has a tab 42 which projects into the housing 14 along the support direction.

In the first embodiment, it is provided that the actuating element 38 is held on the base member 32 about a pivot axis 18 spaced from the pivot axis 44 relative to the base member 32 pivotally. Furthermore, the damper device 36 comprises a first damper part 46, designed as a cylinder, for example, which is connected in an articulated manner to the actuation element 38 or coupled. For this purpose, the first damper part 46 is pivotally connected to the actuating element 38 about a pivot axis 48 spaced from the pivot axes 18 and 44 relative to the actuating element 38.

The damper device 36 further comprises a second damper part 50, which is designed, for example, as a piston or piston element and which is accommodated at least partially on the first damper part 46 and is displaceable relative to the first damper part 46. For this purpose, the second damper part 50 comprises, for example, a translationally movably received in the first damper part 50 and in Fig. 1 unrecognizable piston and connected to the piston and thus with the piston relative to the damper part 46 mitbewegbare piston rod. For example, the first damper portion 46 and the piston define at least one working chamber in which a fluid, such as a liquid or gas, may be received or received. This fluid is used as a damping fluid for damping the relative movements.

In the first embodiment, the second damper part 50 is pivotally supported on the base member 32. In the present case, the second damper part 50 with the base member 32 at one of the pivot axes 18, 44 and 48 spaced, in Fig. 1 unrecognizable pivot axis relative to the base member 32 pivotally connected. Thus, the damper device 36 via the damper part 50, the damper part 46 and the actuator 38 to the base member 32, in particular articulated or pivotable held.

If the door of the household appliance is in its open position, the swivel arm 16 is in its second position. In the second position, the carriage 22 is initially still spaced from the actuator 38, in particular from the tab 42. If the door of the household appliance is closed, so that the pivot arm 16 is pivoted from the second position to the first position, the carriage 22 is relative to the image plane of Fig. 1 moved to the left relative to the housing 14. For example, in an in Fig. 1 shown and disposed between the first position and the second position intermediate position of the pivot arm 16 comes the carriage 22 in support system with the tab 42 and thus with the actuator 38 total. As a result of this support system, the car 22 touches For example, the tab 42. In particular, the carriage 22 comes in a contact point 52 in support system with the tab 42 and thus with the actuator 38th

In other words, the carriage 22 cooperates with the actuating element 38 at the contact point 52. If the pivot arm 16 from the intermediate position continues to move in the direction of and in particular in the first position, so that the carriage 22 further based on the image plane of Fig. 1 is shifted to the left relative to the housing 14, the actuator 38 is moved by means of the carriage 22 about the pivot axis 44 relative to the base member 32. As a result, the damper device 36 is actuated by means of the actuating element 38. For example, since the damper part 50 is pivotable relative to the base member 32 but not slidable relative to the base member 32, the piston is immersed in the cylinder, resulting in a reduction in volume of the working chamber. As a result of this reduction in volume, for example, at least part of the fluid initially taken up in the working chamber is displaced out of the working chamber, in particular pushed, by means of the piston. Alternatively or additionally, at least a portion of the fluid received in the working chamber is compressed. As a result, the movement of the carriage 22 is damped, so that via the carriage 22 by means of the damper device 36, the pivoting of the pivot arm 16 and thus the movement of the door are damped.

Furthermore, it is conceivable that the fluid contained in the working chamber is compressed in the manner of a gas spring by the described reduction in volume of the working chamber. Alternatively or additionally, it is conceivable that as a result of the described damping of the pivot arm 16 and its movement relative to the housing 14, an in Fig. 1 not shown spring element of the damper device 36 stretched, in particular compressed, is. The compressed fluid or the tensioned spring device of the damper device 36 provides, for example, in the first position of the pivot arm 16, a spring force, which via the actuator 38 to the carriage 22 and in this case based on the image planes of Fig. 1 works to the right. The carriage 22 is held, for example by means of the pivot arm 16 against movement.

If the swivel arm 16 is moved, for example, from the first position to the second position, then the compressed fluid or the tensioned spring device of the damper device 36 can at least partially relax, so that the damper part 50 at least partially moved out of the damper part 46 and the actuator 38 relative to the base member 32 is pivoted back. Following this, the damper device 36 is again available to dampen over the carriage 22, the pivot arm 16 when it is moved back to the first position.

By using the damper module 10 as a module component, a modular construction of the hinge 12 can be represented. As part of this modular design, the hinge 12 can be equipped as needed with the damper module 10 and thus used as needed with the damper module 10 or without the damper module 10.

In order to fasten the damper module 10 to the housing 14, the damper module 10 is first supported on the housing 14 along the support direction, so that the actuation element 38, in particular the tab 42, is inserted into the housing 14. Further, for example, the fasteners 34 are inserted through, for example, formed as through holes openings of the housing 14 therethrough. Subsequently, the damper module 10, for example, relative to the housing 14 translationally and thereby with respect to the image plane of Fig. 1 moved to the left. As a result, the hook-shaped fastening elements 34 engage behind respective wall regions of the housing 14, so that the damper module 10 is held on the housing 14 in a form-fitting manner by means of the fastening elements 34. In particular, the fastening elements 34 are latched to the housing 14.

To release the damper module 10 from the housing 14, the damper module 10, for example, based on the image plane of Fig. 1 moved to the right relative to the housing 14, so that the fasteners 34 no longer engage behind the corresponding wall regions. Following this, the damper module 10 can be moved away from the housing 14 against the support direction. An additional, separate connection of the actuator 38 to the carriage 22 is not provided and not required, so that the hinge 12 simple and can be equipped as needed with the damper module 10. As a result, different construction variants of the hinge 12 can be realized in a simple manner.

Fig. 2 and 3 show a second, non-inventive embodiment of the damper module 10 and thus of the hinge 12. In the second embodiment, the damper device 36 is formed as a horizontal damper. This means that the damper part 50 is translationally movable relative to the damper part 46 along a damping direction, wherein this damping direction extends at least substantially parallel to the direction of movement of the carriage 22. In contrast, in the first embodiment, the damper direction is oblique or perpendicular to the direction of movement of the carriage 22. In the first embodiment, the damper direction includes an angle with the direction of movement which is greater than 10 degrees, more preferably greater than 45 degrees, and less than 180 degrees , in particular less than 170 degrees and preferably less than 135 degrees.

In the first embodiment of the invention, the damper part 50 is pivotally connected to the base member 32. In the second, non-inventive embodiment, the damper part 46 is fixed to the base member 32 and thus can be moved relative to the base member 32 neither translational nor rotational. Thus, the damper part 50 can not be rotationally moved relative to the base member 32. Especially good Fig. 2 recognizable are the fasteners 34 which are formed as hooks. Also, in Fig. 2 the designated 54 wall portions of the housing 14 can be seen, wherein formed as a hook fasteners 34 engage behind the corresponding wall portions 54 in the installed position of the damper module 10. As a result, the damper module 10 is held in a form-fitting manner on the housing 14 via the base element 32.

Fig. 2 shows the intermediate position of the pivot arm 16, in which the carriage 22 just comes with the tab 42 and thus with the actuator 38 in support system. Fig. 3 shows the hinge 12, wherein the pivot arm 16 is in its first position. By moving the pivot arm 16 from the intermediate position to the first position, the actuating element 38 is moved by means of the carriage 22 and in this case referred to the image plane of Fig. 3 pivoted clockwise, whereby the damper part 50 is at least partially moved into the damper part 46.

As a result, the pivoting of the actuating element 38 is damped, which in turn dampens the movement of the carriage 22 and, as a result, the pivoting of the pivoting arm 16.

Fig. 4 and 5 show a third, non-inventive embodiment of the hinge 12. Also in the third embodiment, the damper device 36 is formed as a horizontal damper. Furthermore, it is provided in the third embodiment that the actuating element 38 is not held approximately pivotably on the base member 32, but the actuating element 38 is held on the base member 32 relative to the base member 32 movable. In this case, the base member 32 has a receptacle 56 in which the damper device 36 is at least partially received. Furthermore, the actuating element 38 engages in the receptacle 56. By the receptacle 56, a guide is formed, by means of which the actuating element 38 is guided when the actuating element 38 is displaced relative to the base member 32. Furthermore, the actuating element 38 has a receptacle 58, in which the damper device 36, in particular the damper part 50, is at least partially accommodated.

In the second embodiment, the actuating element 38 is designed as a drag lever, via which the damper device 36 is actuated by the carriage 22. In the third embodiment, the actuating element 38 is designed as a slide, via which the damper device 36 is actuated by the carriage 22. The slider (actuating element 38) has on one of the damper device 36 and the base member 32 remote from the side engaging in the housing 14 tab 42 at least one support member 60 through which a support surface 62 is formed. About the support surface 62, the actuating element 38 in the installation position of the damper module 10 on the housing 14, in particular along the support direction, can be supported or supported. The support surface 62 is arranged on a side of the contact point 52 facing away from the damper device 36 or the base element 32. In particular, the support surface 62 is supported in the installed position of the damper module on a side facing away from the carriage 22 of the housing 14, wherein the support surface 62 and the support member 60 can slide along the top, when the actuator 38 relative to the base member 32 and thus relative to the Housing 14 is moved translationally.

In the third embodiment, the actuator 38 is displaced from the carriage 22 relative to the housing 14 as the pivot arm 16 is moved from the second position to the first position. During this displacement of the actuating element 38 relative to the housing 14, the supporting surface 62 or the supporting element 60 slides on the housing 14, in particular on the upper side. This creates a friction between the support element 60 and the housing 14, whereby a braking force is created by this friction, which increases the damping effect for damping the relative movement between the pivot arm 16 and the housing 14.

The advantage of the pivotable actuating element 38 relative to the displaceable actuating element 38 is, for example, that in the pivotable actuating element 38 lever ratios can be adjusted as needed, thereby achieving a particularly high damping effect. In particular, it is possible, for example, to adjust distances between the pivot axis 44 and the contact point 52 and between the pivot axis 44 and the pivot axis 48 and thus respective lever arms as needed. As a result, for example, a damping ratio can be created so that even with only a small distance traveled by the carriage 22 high damping effects or damping forces can be ensured. As a result, the door can be advantageously damped in its movement even when the door has a high weight.

Fig. 4 shows the third embodiment in the intermediate position of the pivot arm 16. If the pivot arm 16 moves from the intermediate position further in the direction of or in the first position, the actuator 38 is pushed by the carriage 22 in the base member 32, in particular in the receptacle 56 , which in turn the damper part 50 is inserted into the damper part 46. Thereby, the respective movement of the carriage 22 and thus of the pivot arm 16 and in the wake of the door is damped.

Fig. 6 to 8 show a fourth, inventive embodiment of the damper module 10 and thus of the hinge 12. In the fourth embodiment, the damper device 36th Double acting, so that the pivot arm 16 is attenuated both during movements from the first position to the second position and during movements from the second position to the first position. In other words, in the fourth embodiment, the carriage 22 is damped both when the carriage 22 relative to the housing 14 with respect to the image plane of Fig. 6 to 8 is moved to the right, so even if the carriage 22 relative to the respective image plane of Fig. 6 to 8 is moved to the left relative to the housing 14.

For this purpose, the damper module 10 comprises at least one on the base member 32 about the pivot axis 44 relative to the base member 32 pivotally held second actuator 64, via which for damping the relative movements between the pivot arm 16 and the housing 14, the damper device 36 is actuated. For this purpose, the second actuating element 64 is adapted to engage in the installation position of the damper module 10 in the housing 14 and to cooperate with the carriage 22 for damping the relative movements. For this purpose, the second actuating element 64 has an engaging into the housing 14 tab 66, via which the carriage 22 can cooperate in its displacements relative to the housing 14. In the fourth embodiment, the damper part 46 is pivotally coupled to the first actuator 38 in the manner described. The second damper part 50 is pivotably coupled to the second actuator 64 so that the damper part 50 is pivotally connected to the second actuator 64 about a pivot axis 68 spaced from the pivot axes 44 and 48 and pivotally relative to the second actuator 64.

Further, the carriage 22 pins 70 and 72, which are arranged spaced apart in the direction of movement of the carriage 22. The tabs 42 and 66 engage between the pins 70 and 72. If the pivot arm 16 is moved from the second position to the first position, then the pin 72 comes into support engagement with the tab 42, so that the actuating element 38 is pivoted about the pivot axis 44 relative to the base element 32. As a result, the damper part 50 dips into the damper part 46, whereby the movement of the carriage 22 and thus the movement of the pivot arm 16 are damped. This is especially good Fig. 7 recognizable. However, if the pivot arm 16 is moved from the first position to the second position, then the carriage 22 comes through the pin 70 in support system with the tab 66 and thus with the actuator 64. As a result, the actuator 64 of the carriage 22 to the Swivel axis 44 pivoted relative to the base member 32, whereby also the damper part 50 is immersed in the damper part 46. As a result, the respective movements of the carriage 22 and thus of the pivot arm 16 are damped. When closing the door is thus the actuator 38 about the pivot axis 44 relative to the image plane of Fig. 7 pivoted clockwise. When opening the door, the actuator 64 by means of the carriage 22 about the pivot axis 44 with respect to the image plane of Fig. 8 pivoted counterclockwise.

The respective other actuating element 64 or 38 comes into supporting contact with the base element 32, so that the respective other actuating element 64 or 38 can not escape, but is supported, so that the damper part 50 can dip into the damper part 46. In other words, initially the actuators 38 and 64 are in, for example, an in Fig. 6 shown starting position or neutral position. If the door is closed, so that the car 22 relative to the image planes of Fig. 6 and 7 is shifted to the left, the actuator 38 is pivoted clockwise relative to the base member 32. Forces acting on the actuating element 64 by the actuating element 38 via the damper device 36 are supported on the base element 32, since the actuating element 64 is in support contact with the base element 32 or comes into support contact with the base element 32. For this purpose, a support surface 74 is formed by the base element 32, on which the actuating element 64 is supported or supported. Thus, via the actuating element 64, the damper part 50 can be supported on the base element 32, so that the damper part 50 can dip into the damper part 46. This is especially good Fig. 7 recognizable.

If - starting from the initial or neutral position - the door is opened so the actuator 64 is pivoted by the carriage 22 in the counterclockwise direction. From the actuating element 64 via the damper device 36 to the corresponding other actuator 38 acting Forces can be supported on the base element 32 via the actuating element 38, since the actuating element 38 comes into support contact with the base element 32 or is in support contact with the base element 32. For this purpose, the base element 32 has a support surface 76, on which the actuating element 38 can be supported or supported. As a result, the damper part 50 can dip into the damper part 46, as a result of which the corresponding relative movements can be damped.

In order to keep the space requirement of the damper module 10 is particularly low, the pivot axis 44 about which the actuator 38 is pivotable relative to the base member 32, the pivot axis 44 about which the actuator 64 relative to the base member 32 is pivotable. Thus, also in the fourth embodiment, the damper device 36 via the actuators 38 and 64, in particular pivotally mounted on the base member 32.
