Description

Handle for a door of a household appliance with a specific light guide, as well as a door and household appliance

One aspect of the invention relates to a handle for a door of a household appliance. The handle has an elongated front bar and at least one handle block which is connected to the front bar. The handle can be positioned on the door using the handle block. The handle also has at least one light source which is arranged in the handle. In addition, the handle has at least one light guide element with which light from the light source can be emitted from the front bar. Furthermore, one aspect of the invention relates to a door for a household appliance. In addition, one aspect of the invention relates to a household appliance.

A handle for a household appliance is known from DE 10 2011 055 279 A1. The handle has an elongated central part, on which ends of the S-shaped, curved grip blocks open in one piece. The handle is arranged on a front of a door of the household appliance via these handle blocks. A light source and a rod-shaped light guide are arranged in this elongated central part of the handle. A front cover of this elongated central part has a continuous gap-like opening, through which the light guide arranged behind it is exposed. Light that is emitted via the light guide radiates through this gap-like opening in the front cover.

In the above-mentioned prior art, in which both the light source and the light guide are arranged in the handle itself, the positioning of the light source and light guide is restricted by the individual shape of the S-shaped handle blocks arranged in extension to the elongated central part. In addition, the light guide is accessible from the front so that it can also be damaged.

In addition, designs of doors are known in which a light source is not arranged in the handle itself, but in the door. In these configurations, the light from the light source on the door side is first radiated into the handle and distributed there individually. Such configurations are under construction elaborate and the light guide complicated. Relatively high light losses can occur. This restricts the light from being emitted via the handle.

It is an object of the present invention to provide a handle for a door of a household appliance, a door and a household appliance, in which a compact and protected construction of the components is achieved and also a light-intensive and flexible generation of light images is made possible.

This object is achieved by a handle, a door and a household appliance according to the independent claims.

One aspect of the invention relates to a handle for a door of a household appliance. The handle has an elongated front bar. In addition, the handle has at least one handle block separate from the front. This handle block is connected to the front bar. The entire handle can be positioned or attached to the door using the handle block. The handle has a light source which is arranged in the handle itself. In addition, the handle has a light guide element separate from the light source, with which light from the light source can be radiated in a defined manner from the front strip. The front bar is designed as an at least partially transparent plate which covers the light guide element on the front. Light that is emitted by the light guide element can be emitted at least through a translucent material area of the front bar. Such a configuration provides a handle in which both the at least one light source and the at least one light guide element itself are contained. It has thus already been achieved that the light from the light source can also be radiated radially from the handle. As a result, light images can be emitted very precisely and with sharp contours and also with high light intensity from the handle itself.

The design with the solid and uninterrupted front bar as a plate creates a front cover element. As a result, the light guide element, which is located behind it, is completely covered on the front. Nevertheless, it is possible that the light which is emitted by the light guide element can be radiated through the front strip in a defined manner. This means that when the handle is viewed from the front and thus when the front bar is viewed from the front, one of the Front bar emitted and emitted light image are generated. This also means that the light guide element is covered by the front bar and when the handle is viewed from the front it can no longer be recognized as such an opposite element. As a result, an improved optical appearance of the handle is also achieved, even if no light image is generated. In particular, this also creates a calmer visual appearance. In this context, the front bar thus serves both as a front end part and thus as a cover, and on the other hand also as a radiation element of the light which is emitted by the light guide element through the front bar. By designing the front bar as a plate, this front bar is made relatively thin. The structure of the handle in a direction perpendicular to the longitudinal axis of the handle, in particular perpendicular to the front bar and in the direction of the handle blocks, is thus reduced.

It can be provided that the light guide element is plate-shaped. Both a flat plate and a certain uneven and deformed plate can be provided in the context. This configuration provides a geometrically specified light guide element which enables particularly extensive light guidance. It is thus possible to emit light over a large length of the front bar from the light guide element into the front bar and from there to the front. Relatively extensive light images with relatively long light lines can thus be generated in a very uniform and homogeneous manner. In addition, such a geometric configuration of the light guide element also creates a mechanically more stable component. It then also helps to stabilize the entire handle. In particular, such a light guide element can also contribute to the position stabilization of other components of the handle.

It is preferably provided that the light guide element is arranged between the front bar and the handle block. This effectively creates a sandwich structure. It can be provided that in such a configuration the front bar is spaced apart and thus arranged in particular in a contactless manner with respect to the handle block.

It is preferably provided that the light guide element is designed to be elastically deformable. In particular, an elastic compressibility of the Light guide element formed in a direction perpendicular to the front bar. In particular, the light guide element is designed to be compressible in a direction perpendicular to its plane. This is a particularly noteworthy version. This is because the light guide element is also formed as a tolerance compensation element. Especially when the light guide element is arranged between the front bar and the handle block, it can also be provided as a specific spacer element by this configuration. Manufacturing tolerances and position tolerances can be compensated for by this elastic compressibility of the light guide element in this specific direction. In addition, due to this elastic deformability, the light guide element can also take on the functionality of a sealing element.

In an advantageous embodiment it is provided that the light guide element is arranged as a compressible spacer element between the front bar and the handle block. In particular, a squeezed arrangement of the light guide element can be formed between the front bar and the handle block in the context. This further improves the advantages mentioned above. This compressed, in particular squeezed, state can be achieved by mechanically connecting the handle block to the front bar. For example, screwing or jamming or latching can be provided here. During this assembly, the light guide element located in between is compressed accordingly, in particular squeezed.

The light guide element preferably has a size that corresponds to a size of the front strip. In particular, the dimensions of the light guide element when viewed on the projection on the front bar are smaller in area or at most the same size as the dimensions of the front bar. An embodiment is also possible in which the light guide element projects beyond the extent of the front strip.

With regard to its plate-like configuration, the light guide element can also have a certain trough shape. In such an embodiment, a peripheral tub rim is provided. This tub rim is preferably the area which rests with one side against a rear side of the front bar and with the opposite side rests against the handle block. In particular, the depression forming the trough shape or trough arranged in such a configuration without contact to the back or inside of the front bar.

In such an embodiment, it can preferably be provided that only this tub rim is elastically deformable, in particular compressible.

It is advantageously provided that the handle block has a support base on its end facing the front bar, on which the light guide element rests in such a way that it is sunk into the handle block at least in some areas. As a result, the light guide element is arranged embedded. A certain degree of positional security is thus achieved. In such an embodiment, the light guide element can be designed as a flat plate. In this embodiment, it is particularly provided that the orientation of the plate-shaped light guide element is parallel to the plane of the front bar. In particular when looking at the projection on the front strip, the light guide element has a flat dimension which is smaller than the front strip. In particular, the light guide element is arranged completely within the surface of the front strip if such a projection is used as a basis.

In this embodiment it can be provided that the light guide element lies flat with its front side on the rear side of the front bar.

In an advantageous embodiment it is provided that the light guide element is arranged recessed in the front bar in such a way that it is completely framed by the handle block on the circumference. A particularly secure position arrangement of the light guide element in the handle block itself is achieved. In such a configuration, a direct abutment of the front bar and the handle block can then be provided.

It is preferably provided that the front bar is rectangular.

In this context, the front bar is an elongated rectangular plate.

It can be provided that when the handle is viewed from the front, the front bar completely covers the light guide element and the handle block. In this Projection view, which is directed perpendicular to the plane of the front bar, the light guide element and the handle block are completely behind the front bar and thus within this area of the front bar. In this regard, there is no lateral projection of the light guide element and / or the handle block.

In an advantageous embodiment it is provided that the front bar is formed in one piece. In particular, it is made of real glass at least in some areas, in particular completely. Such a configuration allows light from the light source to be transmitted through it particularly advantageously. This enables individual light images and / or a high degree of homogeneity of the light image generated. It is also achieved that there is little loss of light when passing through the front bar. The front strip can also be formed at least in regions from synthetic glass.

In an advantageous embodiment, it is provided that the handle block is designed as an elongated channel-like component. In particular, the handle block has a length that is at least 80% of the length of the front bar. The handle block is preferably formed in one piece.

In particular, the area dimension, in particular when looking at a projection perpendicular to the front bar of the handle, of the light guide element is at least 50% of the area of the front bar, in particular at least 60%, in particular at least 70%, in particular at least 80%, in particular at least 90%.

In an advantageous embodiment, the handle block is funnel-shaped on its side facing the front bar. This means that the handle block widens towards the front bar. This enables a stable connection of the front bar to the handle block. On the other hand, this shape of the handle block allows the front bar to reach behind, so that the front bar is also formed as a grip bar that can be gripped and gripped behind. In particular, however, the handle block is formed in such a way that it is not possible to completely grasp the front bar. The limitation of the encompassing is formed by the concavely curved wall of the funnel shape of the handle block. In an advantageous embodiment it is provided that the handle block is hollow. This configuration provides it with a reduced weight, so that the handle is also of reduced weight. Nevertheless, it is very stable. A particular advantage of this configuration is that this cavity of the handle block can be used to hold additional components. In particular, it is provided that the light source is arranged in this cavity of the handle block. It can preferably be provided that the at least one light source is arranged on a bottom of the handle block in this cavity.

The light source can be a light emitting diode. Several light sources can also be part of the handle.

In an advantageous embodiment it is provided that opaque areas are produced on an inside of the front bar. Defined zones can thus be formed, through which the light from the at least one light source of the handle cannot be emitted. Individual light images or light patterns can thus be generated. For example, these can be lines or symbols or the like. In this regard, text can also be generated as light by the light sources. The opaque areas of the front bar can be produced as an opaque film. In particular, such a film can be applied to a rear side of the front bar facing the handle block. Alternatively, an opaque coating can also be formed. This can also be formed, for example, on this rear side of the front bar. In addition, it is possible for the material composition of the front strip to be formed in such a way that individual areas have an opaque material integrated. For example, these can be individually colored glass materials.

Another aspect of the invention relates to a door for a household appliance with a handle according to the above-mentioned aspect or an advantageous embodiment thereof. Another aspect of the invention relates to a household appliance, in particular for preparing food, with a handle according to the above-mentioned aspect or an advantageous embodiment thereof and / or according to a door as mentioned above. If the handle has several light sources, these can also be arranged in such a way that light cones of the emitted light from these light sources overlap in regions on the back of the front strip. In this way, individual brightness zones of the generated light pattern can also be formed. The homogeneity of the photo in the overlapping cone areas can also be increased.

It can be provided that the light source is designed as a multicolor light-emitting diode. It is also possible that there are several light sources in which at least some are each designed to emit light with an individual light color. Different multicolored light images can also be generated in this way. In addition, it is also possible that dynamically changeable light images can be displayed by a plurality of light sources. For example, a running light can be displayed in the context. For example, an operating state of the household appliance can also be displayed optically. A pulsation of at least one light source can also be generated in the event of a dynamic change in the light image. For example, a status display or a warning display can be optically symbolized. Other light images or lighting patterns can also be generated.

In an advantageous embodiment, it is provided that the front bar and the handle block separate from it are connected to one another by mechanical fastening means. For example, these can be screw connections. In this context, it is also possible for bushings, for example for electrical lines, to be additionally formed at the screwing points. The light source can thus be supplied with electrical energy in the handle. The handle can also have an additional display unit. This can also be supplied with energy accordingly. In addition, this configuration can then also be used to transmit data signals via these mechanical connection points. Preferably, three separate screw locations of this type are formed along the longitudinal direction of the handle.

It can also be provided that the front strip is formed from an extruded profile. For example, this can be an aluminum extruded profile or a plastic extruded profile. A front cover of this extruded profile can be formed by a transparent cover. In this embodiment in particular, the light source can then also be arranged in the front strip itself.

In addition, it is also possible that in an advantageous embodiment the light guide element is exposed to the side and / or upwards and / or downwards. In this context, these directions are arranged in a plane which is oriented parallel to the plane of the front bar. This also allows the light guide element to be emitted light not only through the front strip, but also in parallel to the side and / or upwards and / or downwards. In particular, additional or also different light effects can be generated in the context. In particular, an indirect background lighting of the front bar or the handle can take place in the context. In particular, the front bar then appears positioned in front of a corona-like photo.

In particular, in such an embodiment, it can be provided as an alternative to a regionally transparent front bar that the front bar is completely non-transparent. This forms a further independent aspect of the invention relating to a handle for a household appliance.

In this embodiment too, a static light image or a dynamic light image, such as a pulsating light or a running light, can be generated.

With information such as "top", "bottom", "front", "back," horizontal "," vertical "," depth direction "," width direction "," height direction "and the like, those are given for the intended use and arrangement of the household appliance Positions and orientations given.

The features and combinations of features mentioned above in the description and the features and combinations of features mentioned below in the figure description and / or shown in the figures alone can be used not only in the respectively specified combination but also in other combinations or alone, without the scope of Leaving invention. So there are also to be regarded as embodiments encompassed and disclosed by the invention, which are not explicitly shown or explained in the figures, but which emerge and can be generated by separate combinations of features from the embodiments explained. Designs and combinations of features that do not have all the features of an originally formulated independent claim are therefore also to be regarded as disclosed. In addition, versions and combinations of features, in particular those explained above, are to be regarded as disclosed which go beyond or differ from the combinations of features set out in the references of the claims.

Exemplary embodiments of the invention are explained in more detail below with the aid of schematic drawings. Show:

and

Fig. 7 shows a further embodiment of a handle in a schematic sectional view. Identical or functionally identical elements are provided with the same reference symbols in the figures.

In Fig. 1, a household appliance 1 is shown in a schematic representation. The household appliance 1 is designed here for preparing food. It can be an oven. The household appliance 1 has a housing 2 in which a cooking space 3 is formed. This cooking space 3 can be closed at the front by a door 4. A handle 6 is formed on an outside 5 of the door 4 facing away from the cooking chamber 3. The handle 6 is shown in an exemplary embodiment in FIG. 2 and is shown there in a sectional illustration. The handle 6 has a longitudinal axis A. It is placed on the outside 5 and thus protrudes forward from the front relative to this outside 5. In the exemplary embodiment shown, the handle 6 has a front bar 7. The front bar 7 is a flat plate here. In particular, it is formed in one piece. The front bar 7 is preferably made of real glass. In addition, the handle 6 has a handle block 8 separate from the front bar 7. When viewed in the direction of the longitudinal axis A, the handle block 8 is of the same or substantially the same length as the front bar 7. The handle block 8 is in particular in one piece, for example made of plastic or metal. In the embodiment shown here, the handle block 8 with which the handle 6 can be attached to the outside 5 is funnel-shaped. This means that it is widened like a funnel on its side 9 facing the front strip 7, as can be seen in FIG. 2.

It can be provided that the handle 6 is fastened to the door 4 by fastening means, in particular screw connections 10, 11 and 12.

In particular, it is provided that these screw connections 10 to 12 also form a mechanically fixed connection between the front bar 7 and the handle block 8. The screw connections 10 to 12 can also be designed as bushings in order to be able to route electrical lines from the outside of the handle 6 into the handle 6.

In particular, the handle block 8 is hollow at least in some areas. In this context, it thus has a channel shape which widens towards the top. The front bar 7 is dimensioned in such a way that when viewed from a projection, in which one looks in a direction perpendicular to the front bar 7, it completely covers the handle block 8 arranged behind it. With regard to its arrangement and surface dimensions, the handle block 8 is thus completely contained within this projection surface formed by the front bar 7.

In addition, the handle 6 also has at least one light guide element 13. The light guide element 13 is arranged here between the handle block 8 and the front bar 7. A light guide element 13 is generally a light-conducting element defined in its interior, so that light is guided in a defined manner from a coupling-in point of the light-guide element 13 to an exit point of the light-guide element 13.

As can be seen in the illustration in FIG. 3, in which a sectional plane perpendicular to the longitudinal axis A is shown, at least one light source 15 is arranged on a bottom 14 of the hollow handle block 8. The light source 15 is spaced apart from the light guide element 13, which is formed in particular in one piece.

In the embodiment shown in Fig. 3, the light guide element 13 is formed like a plate. In particular, it has a tub shape here. In this connection, the light guide element 13 has, in particular, a web 16 running all the way round. This web 16 can be referred to as a tub web. As can be seen here, the web 16 rests with an upper side 16a on a rear side 7a of the front bar 7. With a rear side 16b, the web 16 bears against an upper edge 8a of the handle block 8. In particular, the front bar 7 is arranged in a contactless manner with the handle block 8 in this embodiment. In this embodiment, the light guide element 13 is thus also formed as a spacer element between the front bar 7 and the handle block 8. The light guide element 13 preferably extends essentially over the same area dimensions as the front bar 7. However, it is not configured and arranged laterally, upwards and downwards to the front bar 7.

It is advantageously provided that the light guide element 13 is elastically deformable, in particular compressible, at least in some areas. In the embodiment in FIG. 3, this compressibility is perpendicular to the plane in which the light guide element 13 extends. In particular, this is compressibility thus in a direction perpendicular to the longitudinal axis A and in particular in a direction which is also oriented perpendicular to a longitudinal axis of the handle block 8. The longitudinal axis of the handle block 8 is oriented parallel to the longitudinal axis A.

The light guide element 13 can thus also be arranged squeezed between the front bar 7 and the handle block 8. In particular, the web 16 can be compressed, in particular squeezed, in this context. The squeezing is generated in particular when the screw connections 10 to 12 are screwed together.

It is provided that light which is emitted by the light source 15 is coupled into the light guide element 13 and exits there in a defined manner at exit points and is radiated through the front bar 7 due to the arrangement and configuration, light L1 then coming from the front bar 7 at the front emerges and appears as a photo within the area of the front bar 7. In an advantageous embodiment it is provided that the light guide element 13, as already mentioned above, is exposed laterally and / or upwards and / or downwards. These directions are oriented in a plane that is parallel to the plane in which this front bar 7 is stretched. This exposed light radiation is shown by L2 in FIG. 3. This means that light can be emitted virtually in two different spatial directions, namely through the light emission L1 through the front strip 7 and also through the light emission L2.

As can also be seen, the back 7a of the front bar 7 is made opaque in some areas. In this connection, this opaque region 17 can be formed on this rear side 7a by printing or a film. Likewise, a material can be provided in the material of the front bar 7, which has this opacity. In the exemplary embodiment, that surface area that extends between the lines identified by 18 is opaque and thus the light L1 can only be radiated through the front bar 7 at the edge zones of the front bar 7.

However, this is not restrictive, but should only be understood as an example. Various other configurations for the transmission of light through the front bar 7 can also be made possible. FIG. 4 shows the design of the handle 6 according to FIG. 3, but with regard to a side view and not in a sectional illustration. The narrow web 16 of the light guide element 13 that runs around in this regard without interruption can be seen. FIG. 5 shows an enlarged representation of subarea I of FIG. 4. It can be seen here that the web 16 ends slightly set back to the dimensions of the front strip 7, in particular to an edge 7b. The same is formed with the upper edge 8a of the handle block 8.

The handle block 8 can be formed from a plastic. For example, this can be a thermoplastic material. This can also be BMC (Bulk Molding Compound). A configuration made of metal, for example a metal die-cast component, can also be provided.

In particular, the light guide element 13 is designed as a collective light guide, through which the coupled light is collected. It can be provided that the light guide element 13 has an eroding structure on a side edge 13a, which is then also the side edge of the web 16.

It can be provided that the edge 7b of the front strip is ground so that the light can be scattered better.

The light guide element can be made of silicone, PVC (polyvinyl chloride), TPU (thermoplastic polyurethane) or similar material. It can also be provided that turbidity and / or scattering particles for homogenizing the light guides are present in the material of the light guide element.

6 shows a further exemplary embodiment of a handle 6 in a sectional illustration perpendicular to the longitudinal axis A. In this embodiment, the light guide element 13 is made smaller in terms of area than in the embodiment according to FIGS. 3 to 5. In this embodiment, the hollow handle block 8 has a base 20. The plate-shaped light guide element 13, which is flat here, sits on this. As a result, the light guide element 13 is arranged, at least in regions, sunk into a cavity 19 of the handle block 8. In particular, a fully embedded arrangement is provided here. 6, it can also be provided that a tint film is arranged on the rear side 7a. This also creates a so-called black panel effect. In the area, the material of the front strip 7 can additionally or instead be formed, for example, as gray glass, which has a transmissivity of in particular less than 90 percent. This can also be done in other examples.

In this embodiment in FIG. 6, a seal between the front bar and the handle block can be produced, for example, by means of a circumferential foam adhesive tape or an adhesive bead.

In addition, a further exemplary embodiment of a handle 6 is shown in FIG. 7 in a sectional illustration perpendicular to its longitudinal axis. In this embodiment, it is provided that the front bar 7 is made of metal, for example as an aluminum extrusion or plastic extrusion. A front cover can be made transparent. In this embodiment there is no light source in the handle block 8, rather it is arranged in the front bar 7 in the embodiment in FIG. In this embodiment, the front cover of the front bar 7, which is formed here in several parts, is convexly curved.
