Description

The invention relates to a hinge for a door of a household appliance, with a hinge base body and an associated and relatively pivotable hinge sword. The invention further relates to a door for a domestic appliance with a hinge, which has a hinge base body and a hinged sword connected thereto and pivotable relative thereto. Moreover, the invention also relates to a domestic appliance with a hinge and a door which is pivotally mounted by means of the hinge to a domestic appliance housing. Furthermore, the invention also relates to a method for actuating a door handle of a door of a domestic appliance.

The GB 2 235 723 A describes a hinge for a door of a dishwasher, wherein a first plate part of the hinge is arranged on a body of the dishwasher and a second plate part of the hinge on a door of the dishwasher.
From the DE 199 23 994 A1 a household appliance hinge device is known. This has a trained as a plate-like sheet metal bracket hinge sword, which is connected to a home appliance housing. The hinge device further comprises a hinge base, which is rotatably mounted with the hinge blade and is also arranged in the door. In the hinge base body, a tension spring is arranged, which is connected to a connecting rod, wherein the connecting rod is in turn connected rotatably connected to the hinge blade. In such an embodiment, the relatively large and heavy hinge body is thus arranged in the door itself. The other arranged therein separate components, in particular the connecting rod and the tension spring, on the one hand are larger components, on the other hand also have a corresponding weight. In the door itself, an arrangement of sub-components of the hinge is thus arranged, which are space-consuming and, moreover, are relatively heavy.

In addition, ovens are known at the door to close a cooking chamber outside a door handle is arranged, which is formed relatively pivotable to this outside. Especially when the door is opened in a completely open end position, the pivoting of the door handle can thus take place to the effect that even with progressive and in particular completely open door, the handle bar is easily accessible to a user and is tangible. If the door is then closed again, the door handle automatically pivots back and stands in front of the door completely closed, in particular vertically back to the front.
It is an object of the present invention to provide a hinge for a door of a domestic appliance, which on the one hand enables a simple transmission of movement to hinge-external components of the door. In addition, also a corresponding door should be created, which further ensures that the operation of the door itself can be done without restriction, however, the hinge portion is formed in the door compact and weight-reduced. In addition, a corresponding home appliance to be created, and a method to be created, with which a reliable and secure handle operation is made possible on a door of a household appliance, given given compact and weight-reduced design of a door arranged in the hinge area.
This object is achieved by a hinge, a door, a household appliance and a method according to the claims. A hinge according to the invention for a door of a household appliance comprises a hinge base body and a hinged sword connected thereto and pivotable relative thereto. These two components form the main components for connection to the door on the one hand and, for example, to a household appliance housing on the other hand to move the door relative to the household appliance housing, in particular to be able to pivot.
On the hinge base body, a transmission element is rotatably mounted, which is coupled to an actuator such that this actuator performs a relative movement to the hinge blade depending on the relative movement between the hinge blade and the hinge body. The transmission element and the actuator are separate components above it In addition, also represent separate components to the hinge body and the hinge sword. By such a multi-component design of the hinge with the very specific connections and couplings, a hinge is created which, on the one hand, allows a transmission of movement to a hinge-external component to be reliably and safely and precisely ensured when the hinge is actuated. This is then done in particular via the actuator. In addition, this construction of the hinge also allows quasi an inverse installation of the hinge is easily possible by namely the hinge sword is connected on the door side and the hinge body is not attached to the door, but for example to a home appliance housing. Since the hinge sword is a very small and weight-minimized component, then the door is only provided with a corresponding light and small hinge component. This can save space in the door. In addition, also force effects in the movement of the door on the hinge blade on the one hand and the hinge body on the other hand can be better distributed and there are less leverage on the hinge blade.

It is preferably provided that the actuator is formed without direct connections to the hinge body. The coupling of the actuator is thus given only indirectly via the transmission element with the hinge body. For a mechanically more stable and in particular for a very uniform and smooth movement, this has significant advantages. The transmission element is in particular connected directly to the hinge base body and the bearing at the connection point simultaneously represents the axis of rotation about which the transmission element is pivotable relative to the hinge base body.

In addition, it is provided that the transmission element and the actuator are rotatably connected to each other relative to each other, in which case in particular only one connection point is formed, which then also represents the axis of rotation. The transmission element is preferably connected only at two points, on the one hand to the hinge base, and on the other hand to the actuator. Through the said components and their rotatable connections a multi-joint and in many ways relative to each other pivotable component arrangement can be created, which favors the above advantages.

It is envisaged that the hinge blade has a guide in which the actuator is guided to perform its relative movement to the hinge blade. Through this very specific connection of the actuator directly to the hinge blade whose precise motion control and thus the precise relative movement of the actuator to the hinge sword is favored. In addition, the actuator is also mechanically stable to a component, namely the hinge sword, connected. The guide is integrated in particular in the hinge blade, so that no further components are required here.

It is preferably provided that the guide has a slot in the hinge blade, in particular. As a result, in a particularly advantageous manner, a linear linear movement of the actuator can be generated relative to the hinge blade, whereby, depending on the movement of the hinge blade, a particularly precise motion transmission can be made from the actuator to the hinge-external component.

In the hinge according to the invention, the actuator is dependent on its movement to actuate the said hinge-external component, which is a door-side arranged functional unit is formed. In a particularly advantageous manner can thus be effected automatically by the taking place when moving the hinge relative movement between the hinge blade and the hinge base body actuation of this door-side functional unit and thus in particular a relative movement of this functional unit to other components of the door to be initiated.

The functional unit is a door handle movable relative to the door, which is arranged on the door. In particular, by the movement of the actuating transmitter, a pivoting movement of the door handle, which is arranged in particular on an outer side of the door, caused. In particular, this relative movement of the door handle is caused relative to a front window of the door.

It is preferably provided that the transmission element is a double hoop, which has two spaced-apart plate-like bracket. Thereby a mechanically very stable component can be created, which can also be exposed to high mechanical forces during movement.

In particular, these two brackets are arranged parallel to one another and connected to one another via a bolt. Preferably, this pin also forms the connecting part to the hinge body, so that this pin also forms the axis of rotation.

In a particularly advantageous manner, it is provided that the actuating transmitter extends into the free space between the mutually parallel bracket inside. This allows a very compact and space-minimized design can be created, which also allows a particularly mechanically stable connection of the components.

Preferably, it is provided that the hinge blade has two plate-like parts which are arranged parallel and spaced from each other. Again, the above-mentioned advantages in terms of mechanical stability can be mentioned. It is particularly advantageous if these two plate-like parts of the hinge blade extend into the free space between the parts or brackets of the transmission element.

In particular, it is advantageous if the actuating transmitter extends into a free space between the two plate-like parts of the hinge blade. In addition to a very space-saving design, the above-mentioned leadership of the actuator in the leadership of the hinge blade can be achieved particularly advantageous. In particular, a two-sided connection of the actuator on the two plate-like parts can thus be effected here. In particular, namely, the two plate-like parts each have a guide, in particular a slot, in which hineinerstreckt the actuator with arranged on opposite sides guide pin.

The actuator is in particular a one-piece plate-like strip, which can also be referred to as a push rod.

In another embodiment, it can also be provided that the hinge blade only has a plate-like body which extends into the free space between the plate-like brackets of the transmission element.

It is advantageously provided that a further separate component, namely a holding element, is arranged on the hinge bar. This retaining element is movable relative to the hinge blade. It can be positioned in different positions relative to the hinge bar. In this case, a holding position may be formed, which is designed for abutment on the hinge base body in a different intermediate position between the hinge blade and the hinge base body to the two end positions. This means that the intermediate position between the two components mentioned relative to the hinge base body relative to the two end positions of the hinge blade is held automatically by this retaining element in its holding position and without any further action by a user. The holding position is characterized in particular in that in this the door can be removed from the home appliance housing. This holding element thus also serves as a stop or position locking element. In particular, the retaining element is a flap or a bracket. It is rotatably mounted on the hinge bar. In a first basic position, which is different from the holding position, the holding element extends with its longitudinal axis parallel to the longitudinal axis of the hinge blade. As a result, a very tidy and space-saving arrangement can be created. In addition, the holding element in this end position also serves to lock the door when it is arranged in the closed state and thus also the hinge blade and the hinge base body have reached a first end position in which they with their longitudinal axes substantially at an angle of 90 ° oriented to each other.

In addition, in such a first end position of the hinge, it is also provided that the longitudinal axis of the actuating transmitter is oriented parallel to the longitudinal axis of the hinge blade and thus in particular perpendicular to the longitudinal axis of the hinge base body. In this first end position of the actuator is pushed out with a maximum length on a front side of the hinge blade. In this case, the front side represents the side facing the door and thus the side facing away from the hinge base body.

The actuator is in particular arranged so that it extends out of the hinge body facing away from the side of the hinge blade out and its relevant length regarding the stretching out depending on the movement between the hinge blade and the hinge body is changeable.

In this first end position of the hinge blade and the hinge base body to each other, the transmission element is arranged in an inclined position with its longitudinal axis, which is arranged at an angle between 40 ° and 60 °, in particular 45 °.

It is preferably provided that the two centers of the axes of rotation, on the one hand allow the rotation between the hinge blade and the hinge base body and on the other hand, the rotation of the transmission element to the hinge body, lie on a straight line which is parallel to the longitudinal axis of the hinge body.

On the other hand, it is provided that the centers of the axes of rotation on the one hand between the hinge blade and the hinge body and on the other hand lie between the actuator and the transmission element on a straight line which is parallel to the longitudinal axis of the hinge blade.

In the already mentioned first end position between the hinge blade and the hinge base, these two straight lines, which extend between in each case two centers of the axes of rotation, are perpendicular to one another.

In a second end position between the hinge blade and the hinge main body, which represents the opened state and thus also the open state of a door relative to a domestic appliance housing, these two straight lines run parallel, in particular they are located on a common straight line.

It is preferably provided that the hinge base body has an elongated housing in which a tension spring connected to the hinge blade is arranged. The tension spring is used in particular for assisting movement in the door opening, wherein they when opening the door is stretched and thus generates a correspondingly greater drag. The tension spring is preferably connected with its hinged sword end facing with another separate component, in particular a coupling element, which is rotatably connected to the hinge blade. With another end, the tension spring is arranged on a stationary connection element in the housing of the hinge base body.

It can also be provided that the hinge base body has a damper, with which the movement of the door is at least partially attenuated over the entire path of movement. In particular, such a damping takes place within a movement path shortly before reaching the closed position and thus the first end position of the hinge, in which then the door is in the closed state. The damper is arranged in particular in the housing of the hinge base body.

The invention further relates to a door for a domestic appliance, which has at least one hinge with a hinge blade and a hinge base body, wherein the hinge bar is arranged on the door and is connected to the door. The hinge base is in particular connected to a household appliance housing. Such an arrangement of a hinge allows a very weight-reduced and space-minimized component of the hinge, namely the hinge bar, in the door, and the much larger and heavier component, the hinge base, door outside and is arranged in the home appliance housing. The above advantages can be achieved thereby.

In such an arrangement of the hinge is provided that a hinge according to the invention or an advantageous embodiment thereof is formed. For then again a corresponding coupling can be ensured with a arranged on the door handle and automatically the movement of the hinge components are transmitted relative to each other on the door handle, so that it is automatically pivoted. In particular, the invention also includes a door for a household appliance, which, regardless of the arrangement of the hinge, has a hinge according to the invention or an advantageous embodiment thereof.

It is preferably provided that a door handle formed as a functional unit is arranged on an outer side of the door and can be pivoted relative to the door, depending on the movement of the door. Even when the door is opened and brought in particular in its open second end position, the user can still easily grasp the door handle, as this was pivoted horizontally with his handlebar and thus is tangible from the front. If the door is then closed again, the door handle automatically pivots from this reached end position back to its starting position, when the door is completely vertical and is closed, and then in particular perpendicular to the outside of the door again protrudes forward. The design can be formed both at bottom hinged doors that can be pivoted about a horizontal axis, as well as doors that are struck laterally and are pivotable about a vertical axis of rotation.

Preferably, a coupling unit is arranged in the door, which is connected to the actuator of the hinge on the one hand and the door handle on the other hand, and by means of which the movement of the actuator on the door handle is transferable.

Preferably, the coupling unit has a carriage biased in position with a spring, which is connected to the actuator, and which is arranged in the door relatively displaceable.

In particular, it is provided that the carriage is connected to a cable pulling device which is connected to the door handle. The carriage includes for this purpose in particular a deflection pin on which the cable of the cable is arranged and deflected. Depending on the displacement of the carriage and then this deflection pin is linearly displaced in a linear direction, which brings about effects on the rope, which is connected at the other end to the pivoting mechanism of the door handle.

Moreover, the invention also relates to a domestic appliance with a hinge according to the invention or an advantageous embodiment thereof and / or a door according to the invention or an advantageous embodiment thereof.

Preferably, it is provided that the door has two such hinges, by means of which a connection to the household appliance, in particular to a household appliance housing, is given.
The invention further relates to a method for actuating a handle on a door of a domestic appliance, in which the door arranged on at least one hinge according to the invention is pivoted on a domestic appliance housing. A hinged hinge of the hinge is connected to the door and a hinge base is connected to the home appliance housing. On the hinge base body, a transmission element is rotatably mounted, which is coupled with an actuator such that it performs a relative movement to the hinge blade depending on the relative movement between the hinge blade and the hinge body and initiates a movement of the door handle depending on the relative movement of the actuator or is triggered.
Advantageous embodiments of the hinge according to the invention and the door according to the invention are to be regarded as advantageous embodiments of the method according to the invention. In particular, it is provided that the said objects and components for performing sequences of movements between the individual components are connected and coupled accordingly, so that then the movements are transmitted accordingly and the operation and movement of the door handle takes place.
In particular, it is provided that, depending on the relative movement between the hinge blade and the hinge base body, the actuation transmitter pushes out and retracts in a defined manner via a front side of the hinge blade, which faces away from the hinge base body. In particular, it is provided that the actuator is retracted in a second end position of the hinge blade relative to the hinge base, which corresponds to the open state of the hinge, maximum in the hinge blade. In contrast, when moving the hinge sword starting from this second end position in the first end position, in which the door is then closed, the actuator is pushed forward from the hinge blade, in the first end position then the maximum Ausschiebeposition is reached.

The actuator is guided in a slot of the hinge sword.

Preferably, it is provided that for removing and removing the door and thus separating the door from the domestic appliance housing, a holding element, which is rotatably mounted on the hinge bar, is pivoted from an end position to a holding position. If the door is then moved, for example, from a fully open position in the direction of the closed position, the holding element located in the holding position is guided on this movement path to a stop of the hinge base body, so that the further movement of the door in the direction of the closed position is prevented is. The door has then reached an intermediate position in which the removal is possible. The intermediate position is automatically held by the holding element which is struck on the hinge base body.

Due to the interlocking arrangement and quasi-nested positioning of the components hinge body, transmission element, actuator and hinge blade can also be a very protected arrangement can be achieved so that in a relative movement and no spreading or jamming can occur. Especially when disassembling the door in the intermediate position is prevented by this arrangement and nesting of the components that a user tweaks or otherwise can access the components, so that high security is ensured here.

Preferably, it is provided that the hinge blade and in particular the actuating transmitter open into a door profile arranged on the inside of the door, wherein the coupling unit, in particular with the carriage and the cable pulling device, is arranged in the door profile. This also ensures a very tidy, space-saving and protected arrangement of the components on the door side. In particular, the door profiles have elongated, shaft-like housing receptacles in which these components are arranged. In particular, this also a screen is guaranteed on the door side.

In the figures, identical or functionally identical elements are provided with the same reference numerals.

In Fig. 1 is shown in a schematic perspective view of an oven designed as household appliance 1. However, the domestic appliance 1 may also be, for example, a microwave cooking appliance or a steam cooking appliance or the like. It may also be a dishwasher, etc., for example.

The domestic appliance, hereinafter referred to as oven 1, comprises a cooking chamber 2, which is bounded by a muffle 3 and its walls. The muffle 3 has on the front side a charging opening, which can be closed by a door 4. In the exemplary embodiment, the door 4 is a bottom hinged door, which is pivotable about a horizontally oriented axis A. The door 4 is attached via two hinges 5 and 6 to a household appliance housing 7 and pivotable relative thereto.

The oven 1 further comprises an operating device 8, which has a display unit 9 and operating elements 10 and 11. Both positionally and in terms of the number, the display unit 9 and the controls 10 and 11 are to be understood as exemplary only. The same applies to cooking zones 12, 13, 14 and 15, which includes the oven 1.

On the door 4, which has a front screen 16, a horizontally oriented handle 17 is arranged, which is pivotable about a horizontally oriented axis B relative to the front screen 16. The handle 17 can be pivoted depending on the movement of the door 4. It is coupled to the hinges 5 and / or 6 by means of specific and subsequently explained devices. If the door 4 is in the fully closed state and is thus vertical, the handle 17 is in a first basic position, in which it is virtually perpendicular to the front. This relates in particular to the unspecified and illustrated handle bars, via which a handle bar of the handle 17 is arranged on the windscreen 16.

If the door 4 is opened and moved in the direction of its fully opened second end position, the handle 17 is automatically pivoted about the axis B. The handle bar of the handle 17 is thus almost always facing the user, so that they can easily grab them. In the fully open state of the door 4, in which it is oriented horizontally with its front panel 16, thus showing the handle bar 17 is not in the direction to the ground, but is so pivoted that it again points to the front and can be gripped by a user even with the door 4 fully open.

In the exemplary embodiment, it is provided in particular that the hinges 5 and 6 each have a hinge blade and an associated hinge base body. The hinge blades of the hinges 5 and 6 are connected to the door 4, whereas the hinge base body are in the appliance housing 7.

Hereinafter, exemplary embodiments of the hinges 5 and 6 are explained in more detail. Since the two hinges 5 and 6 are constructed analogously, the following description is made on the basis of the hinge 5.

In Fig. 2 is shown in a perspective view of the hinge 5 in section. The hinge 5 in this case comprises an already mentioned hinge base body 18 which comprises a housing 19. In addition, this hinge base 18 is rotatably connected with its housing 19 with the already mentioned hinge blade 20. For this purpose, a bolt 21 is provided, so that a rotation about an axis C between these two components is ensured.

As can be seen, the hinge blade 20 is formed with a first plate-like part 20a. Parallel and spaced therefrom is a second plate-like part 20b of the same design (FIG. Fig. 5 ), whereby the hinge blade 20 is formed. The hinge blade 20 extends on a side facing away from the hinge base 18 side 20c in a door profile 4a. This is arranged on an inner side of a door glass, in particular glued. The door profile 4a is an elongated, hollow component.

At this point, it should be mentioned that the door 4 has at least the front screen 16. However, the door 4 preferably comprises at least one further inner door pane, which is arranged at a distance from the front pane 16. In addition, even more washers may be present. The door profile 4a is arranged on the inside of the cooking chamber 2 nearest and facing door glass.

The hinge 5 furthermore comprises a transmission element 22 provided as a separate component. This transmission element 22 comprises a first plate-like bracket 22a and a spaced-apart and parallel extending second plate-like bracket 22b ( Fig. 5 ).

The two brackets 22a and 22b of the transmission element 20 are connected to a bolt 23. By means of this bolt 23, a direct connection of the transmission element 22 with the housing 19 of the hinge base body 18 is given. The trained as a double bow transmission element 22 is thereby arranged about the axis D of the bolt 23 is relatively rotatable to the housing 19.

The transmission element 22 has no direct connection to the hinge blade 20.

In addition, the hinge 5 also comprises an actuating transmitter 24 designed as a separate component. This is formed in one piece and, as shown in FIG Fig. 2 to recognize, designed as an elongated straight strip, where it can also be referred to as a push rod. The actuator 24 is coupled via a connecting pin 25 with the transmission element 22. The bolt 25 has a longitudinal axis E, which is oriented parallel to the axes C and D. About this longitudinal axis E, which also represents the axis of rotation, the actuating element 24 is rotatable relative to the transmission element 22.

A longitudinal axis F of the actuating element 24 extends parallel to a longitudinal axis G of the hinge blade 20.

In addition, it is provided that the actuator 24 extends with its front end 24a on the front side 20c of the hinge blade 20 addition.

In Fig. 2 a second end position of the hinge 5 is shown, in which the fully open state is shown, which then also characterizes the fully open state of the door 4.

In this arrangement it is provided in particular that cross-section centers of the bolts 21, 23 and 25 lie on a straight line which then extends parallel to the longitudinal axes F and G.

In Fig. 2 In addition, it can still be seen that there is a holding element 26 on the hinge blade 20, in particular the two plate-like parts 20a and 20b. The holding member 26 is rotatably attached to these plate-like parts 20a and 20b. In Fig. 2 is the first end position shown.

In the illustration according to Fig. 3 is the hinge 5 as shown in FIG Fig. 2 shown in a first end position, in which the door 4 is in the fully closed state. In this arrangement, the hinge blade 20 is oriented vertically with its longitudinal axis G, whereas the housing 19 and thus also the hinge base body 18 is still oriented horizontally with its longitudinal axis H oriented.

As in this view according to Fig. 3 can be seen, in the two plate-like parts 20a and 20b each have a slot 27 and 28 ( Fig. 5 ) educated. The elongated holes 27 and 28 are guides in which the bolt 25 is guided. The actuator or the actuator 24 can therefore only move in a linear linear movement relative to the hinge blade 20 forward and backward. In Fig. 3 is shown in this first end position of the hinge 5 of the fully and thus maximum extended state of the actuator 24.

As can also be seen, a front end 24a of the actuator 24 is in contact with another pin 29 which is guided in a slot 30 of the door profile 4a. The bolt 29 is associated with a coupling unit, by means of which the movement of the door handle 17 depending on a movement of the hinge 5 and / or the hinge 6 is effected. By means of the hinge 5 and in particular of the actuator 24 can thus be dependent on the relative movement between the hinge blade 20 and the hinge body 18, a hinge-external component, namely the door handle 17, automatically operated.

In this first end position of the hinge 5 as shown in FIG Fig. 3 are the cross-sectional centers of the bolts 21 and 23 on a first straight line extending horizontally, said straight line is perpendicular to the straight line extending through the cross-sectional centers of the bolts 21 and 25.

In Fig. 4 is shown in a further perspective sectional view of the hinge 5 in an intermediate position. In this intermediate position, a locking of the position of the door 4 is ensured. This is made possible in that the holding element 26 of his in Fig. 2 and Fig. 3 shown first end position is folded up and is posted on a stop 31 on the housing 19. The door 4 can thus no longer automatically and automatically go into this fully closed position in this intermediate position. In this intermediate position of the hinge 5 and thus also the door 4, the door 4 can be removed from the domestic appliance housing 7.

By the holding member 26 is in the illustration according to Fig. 3 in which the door 4 is arranged in the closed state, this also locked.

In Fig. 5 is shown in a perspective view, the hinge 5, wherein also a partial section is shown here. In contrast to the representation in Fig. 2 showing the same second end position of the hinge 5, here the transmission element 22 and the hinge blade 20 and the holding member 26 are shown in their entirety.

In addition, it can also be seen that the hinge blade 20 and the actuator 24 extend into the interior of a hollow part 4b of the door profile 4a, wherein this hollow part 4b is formed as a shaft in which the bolt 29 is secured over pins 32 out. The split pins 32 also secure a cable 33, which is associated with a cable pulling device.
