Description

The invention relates to a device for a household appliance and a household appliance with such a device.

It is known that household appliances, such as an oven, have a door for closing a cooking chamber. The door may be a hinged door which is pivotable about an axis. However, the door may also be designed so that it can be sunk in a receiving space under the cooking chamber when it is converted, starting from the closed state in the open state.

In addition, doors for such ovens are known in which a door handle arranged on the outside is movable relative to a plate-like base part. Also, such a pivoting brings advantages, since then with completely open door this door handle can also be used in a user-friendly and the door can be moved. In the context, embodiments are known in which this pivotable door handle is connected by means of a coupling device in the form of a cable with corresponding components, so that automatically pivoted at a Türverschwenkung this cable pull the door handle.

In conventional doors, it is also known that a hinge, which is provided for connecting the door to the housing of the household appliance, with a smaller hinge blade and a hinge housing as two hinge parts, which are rotatably coupled to each other is formed. In the much larger hinge housing more functional parts, such as a spring or the like are included. Previous designs have provided that this hinge housing is fixed on the door side and the hinge blade is mounted on the housing side. In newer embodiments, it is provided that in hinged version the hinge blade is connected to the door and the hinge housing is fixed in the household appliance housing.

It is an object of the present invention to provide a device for a household appliance and such a household appliance, in which or in which a simple and user-friendly assembly and disassembly of the door can be done by the hinge.

This object is achieved by a device and a household appliance according to the independent claims.

A device according to the invention for a household appliance comprises a door with a plate-like base part, on which a handle is arranged. The device further comprises a coupling device, which is connected to the handle and through which the handle is pivotable relative to the base depending on the movement of the door. The device further comprises a hinge which has two relative to each other and interconnected hinge parts, over which the door is pivotable on the household appliance. An essential idea of the invention lies in the fact that the hinge is non-destructively releasably releasably connected to the door and the coupling device with the door connected to the first hinge part non-destructive. Such a configuration allows a simple and user-friendly assembly and disassembly of the door from the hinge even in a configuration with a door handle pivotable relative to the base.

In particular, it is provided that the non-destructive detachable connection between the coupling device and the hinge part, for example, automatically coupled during assembly and thus in an assembly of the components. This is particularly user-friendly and simple, since thus in the assembled mounted end position of the two components to each other, these are automatically coupled already mechanically.

It is preferably provided that the coupling device has a lug-like end piece which can be coupled to the first hinge part. This allows a very targeted coupling. On the other hand, the freedom of movement and the possibility of movement between the coupling device and the first hinge part is maximized and there are no unwanted space wasting occurring. It is preferably provided that this tab-like end piece is a sheet metal strip. This makes it on the one hand very flat construction, on the other hand mechanically very stable design. On the one hand, an unwanted release of the coupling can be avoided on the other hand, a robust mechanical design can be provided, which also works permanently reliable and is wear-resistant.

It is preferably provided that the end piece is elastically deformable. In particular, when the tail is designed for example of spring steel, it can be resiliently reversibly deform in particular in one direction, which is practically perpendicular to the broad surface side of this strip. This elastic deformability ensures easy handling and decoupling of the first hinge part, especially during disassembly. This configuration of the elastic deformability of the end piece, it is possible that no additional additional assembly components, such as screws or the like, are required in order to connect the tail to the first hinge part can. Rather, a component is provided by this configuration of the tail, which automatically generates a certain coupling force with the first hinge part in the coupled state by its shape and spring action and this coupled state is then automatically held. By then such a deformation is also effected by this elastic deformation possibility starting from the coupled state, a decoupling and thus disassembly can also be achieved very easily. Again, then during disassembly no loosening a screw or the like is required, so that the disassembly state is reached faster. Not least, this also saves components with regard to the connection between the hinge part and the end piece.

It is preferably provided that a receptacle is formed in the end piece, in which engages in the coupled with the first hinge part state arranged on the first hinge part coupling pin. On the one hand, such a coupling design is very effective and very direct relative to the motion transmission. Component tolerances and extensive component chains that form between the door handle and the first hinge part are thereby avoided. Not least, such a coupling between a bolt and a receptacle is also mechanically very stable, simple and functionally reliable.

It is preferably provided that the receptacle is a slot in which the coupling pin is movable relative to the end piece depending on the movement of the first hinge part. The advantages mentioned above are thereby further favored. Incidentally, a certain motion guide device for the coupling pin is created by the slot.

It is preferably provided that the receptacle is formed in a plate-like central part of the end piece. As a result, a very flat construction is also possible with regard to the lateral space and on the other hand selected a relatively large-scale part of the tail as such a direct coupling point. The slot can be designed and shaped situation specific in this plate-like middle part, so that the motion sequences and the power transmission to the individual components are improved.

It is preferably provided that the end piece is connected to a connecting device, which is connected to the handle for moving it depending on the movement of the door. This connection device may comprise a rigid guide part and / or a cable device. The tail is thus not directly connected to the door handle, but indirectly coupled via this connection means, so that here too different configurations of a door can be accommodated.

It is preferably provided that the end piece is arranged on the door such that it is automatically brought into engagement with a coupling pin arranged on the first hinge part when the door is connected to the first hinge part. The advantages already mentioned are essential.

It is preferably provided that the end piece comprises a relative to a plate-like central part of the end piece away from the first hinge part end part as a release tab. This embodiment is particularly advantageous for disassembly and decoupling, since thereby the release tab can be easily mechanically contacted with their specific position to a central part, then in particular the elastic deformation and in particular the Wegbieten the tail of the first Hinge part, in particular in a direction perpendicular to a plate-like surface, in particular to this plate-like central part is reached. Such a plate-like central part comprises compared to the side edges or narrow sides of a large-scale front and a back or a large-scale front surface and a large-scale rear surface. The said bending direction or spring direction is then perpendicular to these large surfaces and not on the narrow edge sides.

It is particularly preferred that a release element is arranged movably on the hinge, with which, depending on the movement, pushing away of the end piece located in the coupled state with the first hinge part of the first hinge part can be effected. It is thus achieved here by pressing the release element automatic decoupling of the tail with the hinge part. This is particularly preferred when this release element automatically when moving, in particular turning mechanically attacks the release tab and bends away by the further movement of the release element this release tab and thus the tail of the first hinge part, so that the decoupling between the tail and the first hinge part, in particular with the coupling pin is reached. A particularly simple and user-friendly decoupling and thus disassembly is achieved.

Preferably, it is provided that by turning, in particular about an axis of rotation in the direction of pushing away the end piece, the release element, a release hook of the release element engages behind the end piece, in particular a sloping end portion of the end piece, between the end portion and the first hinge part and upon further rotation the release element, the end piece is pushed away from the first hinge part and dissolved, in particular a coupling pin of the first hinge element is released from a receptacle in the end piece. The above advantages are particularly noteworthy in this specified embodiment.

In a particularly advantageous manner, it is provided that the first hinge part is a hinge blade and the second hinge part is a hinge base body or a hinge housing. In particular, the device is thus designed so that the door can be coupled to the hinge blade and the hinge housing or the hinge base body is arranged and fixed in a housing of the household appliance. Just In such embodiments, it is particularly advantageous that when disassembling the door from the hinge also a very simple and previously unrealizable decoupling provided for the door handle movement coupling device is achieved with the hinge.

Furthermore, the invention relates to a household appliance, in particular a cooking appliance, preferably an oven, with a device according to the invention or an advantageous embodiment thereof.

Further features of the invention will become apparent from the claims, the figures and the description of the figures.

Fig. 3

an enlarged view of a partial section of Fig. 2

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

In Fig. 1 is shown in a schematic representation of a cooking appliance, in particular oven designed household appliance 1. The household appliance 1 comprises a housing 1a, in which a cooking chamber 2 is formed. The cooking chamber 2 is bounded by walls of a muffle 3, which has a feed opening at the front. The cooking chamber 2 is closed at the front by a door 4. The door 4 is configured in the embodiment as a hinged door and can be pivoted about a lower horizontal axis A relative to the housing 1a. The door 4 is hinged to the housing 1a via hinges 5 and 6. The hinge 5 comprises a hinge blade 5 a designed as a first hinge part, which is connected to the door 4, in particular a plate-like base part 4 a of the door 4, which has door panes and possibly door profiles. The hinge 5 further includes a hinge body 5b and a hinge housing which is rotatable relative to the hinge blade 5a and connected thereto. The hinge base 5b is fixed in the housing 1a. It is a component in which, for example, further springs and the like of the hinge are arranged. In an analogous manner, the hinge 6 is constructed.

The muffle 3 comprises at the front a flange 7, against which the door 4 rests in the closed state in the exemplary embodiment.

For example only, the household appliance 1 comprises an operating device 8, which is shown schematically and exemplarily both in terms of position and in terms of design. The operating device 8 comprises a display unit 9 and operating elements 10 and 11. In addition, the household appliance 1 also includes by way of example cooking zones 12, 13, 14 and 15, which are also to be understood schematically in number and position and not exhaustive.

On an outer side 16 of the plate-like base part 4 a of the door 4, a handle 17 is arranged. The handle 17 is movable relative to the plate-like base part 4 a, in particular pivotable about a horizontal axis B. Thus, starting from the closed state of the door 4, in which the handle 17 is then in its basic position, this is gripped and carried out when opening and thus pivoting the door 4 about the axis A pivotal movement of the handle 17 about the axis B. Even in the fully open state of the door 4, which then oriented substantially horizontally is and thus almost in the xy plane, a user can then grab the then pivoted by 90 ° door handle 4 front.

It is thus possible that automatically the handle 17 is pivoted depending on the movement of the door 4. For this purpose, a device 18 is provided, with which the handle 17 is coupled to the hinge 5.

In the embodiment of the household appliance 1, it is provided that the door 4 can be completely reversibly removed from the hinge blade 5a in a non-destructive manner and thus decoupled or disassembled. For this purpose, it is also provided that the coupling device 18 which is connected to the hinge 5, according to non-destructive reversible decoupled. For this purpose, as shown in Fig. 2 , which is a perspective enlarged sectional view I of Fig. 1 shows, provided that the coupling device 18 is non-destructive releasably connected to the hinge blade 5a and the hinge 5 non-destructively releasably connected to the door 4.

In Fig. 2 the positional state is shown, in which the door 4 is fully closed, so that the hinge blade 5a is oriented substantially perpendicular to the hinge base body 5b. The hinge blade 5a is rotatable about the pivot pin 5c relative to the hinge base 5b fixed to the housing 1a. By the bolt 5 c and the axis of rotation A is realized.

On the hinge blade 5a, a coupling pin 19 is arranged. The coupling device 18 comprises an end piece 20, which is designed as a tab-like end piece, which is coupled to the hinge blade 5a. The end piece 20 is a sheet metal strip which is formed of spring steel. It comprises a plate-like central part 21, on which an end part 22 is formed integrally downwardly. The end portion 22 is formed as a release tab and is inclined to the central part 21, in a direction obliquely downward and oriented away from the hinge blade 5a.

In the middle part 21, a receptacle designed as a continuous opening is furthermore designed, which in the exemplary embodiment is a slot 23. Through this slot 23, the coupling pin 19 extends in the coupled state therethrough. The middle part 21 is on the opposite side of the end portion 22 in a slightly tortuous Connecting strip 24 via which is connected to a connecting device 25. The connecting device 25 may comprise a rigid guide part and / or a cable device and is connected to the door handle 17.

In Fig. 2 the coupled state of the coupling device 18 is shown with the hinge blade 5a. Due to the spring action of the end piece 20, this automatically presses against the hinge blade 5a.

On the hinge 5, in particular the hinge blade 5a, a release element 26 is arranged. How to do it in Fig. 3 , which is an enlarged view of a partial section of the illustration in Fig. 2 As can be seen, the release element 26 comprises a securing element 27. The entire release element 26 is rotatable about an axis C, which is perpendicular to the wide and large surface area of the hinge blade 5a and in particular oriented parallel to the axis A. The release element 26 is thus also rotatable about an axis C, which is substantially perpendicular to the large surface area of the central part 21.

The securing element 27 is in the in Fig. 3 It is at a level of the middle part 21 and the end part 22 with a securing bracket 27a slightly spaced from the middle part 21 and the end part 22 and in this respect on the opposite side to the hinge blade 5a , An undesired loosening of the end piece 20 by lifting off the bolt 19 is thereby prevented.

If, on the other hand, a decoupling of the end piece 20 from the coupling bolt 19 and thus also from the hinge blade 5a takes place in the desired manner, then the release element 26 is moved about the axis C, starting from the in FIG Fig. 3 shown state rotated according to the arrow G.

The release element 26 comprises a release hook 26a, which is formed as a plate-like strip and on a base portion 26b, which is plate-like, adjacent and is positioned inclined thereto. The inclination of the plate-like release hook 26a, which is designed as a substantially strip-shaped flat plate, on the other hand, is oriented away from the hinge blade 5a. Upon rotation of the release element 26 about the axis C, the release hook 26a is brought to a rear side 22a of the end part 22, and upon further rotation, due to the position and orientation of the release hook 26a and the position and orientation of the end part 22, it is elastically pushed away by correspondingly generated lifting forces from the hinge blade 5a in the direction of the axis C. and thus also a decoupling of the coupling pin 19 of the slot 23 achieved. In this then reached decoupled end position the end piece 20 is held against its spring action in the decoupled state and the door 4 can be lifted or removed from the hinge blade 5a. In this case, the tail 20 strokes past the coupling pin 19, without this would still protrude into the slot 23 or snap back into it.

Starting from this decoupled state, an automatic coupling can then be generated when mounting the door 4 on the hinge 5, since this can be guided by the mechanical stability in design of the end piece 20 almost automatically on the hinge bar 5 and then snapping the coupling pin 19 in the slot 23 is made automatically when the door 4 is coupled in the final state with the hinge 5.
