Description

Cooking appliance

The invention relates to a cooking appliance with a cooking chamber which is delimited by walls of a muffle and which has a feed opening on the front side, which is bounded on the circumference by a front edge of the muffle. The cooking appliance further comprises a lighting device with at least one light source.

There are cooking appliances, known as ovens, which have different insertion levels for baking trays, grilles and the like in the oven. On the different shelving levels then these food supports can be introduced and the food to be cooked is prepared. There are also known cooking appliances in this context, in which these shelf levels as well as the entire oven can be illuminated by a lighting device. From DE 10 2005 044 347 A1 an oven with a corresponding lighting device for illuminating a cooking chamber is known. In this, the light sources, which are formed as light emitting diodes, arranged outside the cooking chamber. For this purpose, they are integrated into a side wall of the muffle, to which a partition wall is arranged between the light source and the muffle space. In addition, insulating material is also provided between the partition wall and the light source.

It is an object of the present invention to provide a cooking appliance in which the positioning of a light source of a lighting device outside the cooking chamber can be improved.

This object is achieved by a cooking appliance having the features of claim 1.

An inventive cooking appliance comprises a cooking space in which food can be prepared. The cooking chamber is limited by walls of a muffle. The muffle has a front feed opening. The feed opening is peripherally limited by a front edge of the muffle. The cooking appliance also includes a lighting device with at least one light source. The at least one light source is designed for illuminating the cooking chamber and / or for displaying information and is positioned outside the cooking chamber. When viewed from the front of the cooking appliance, this light source is arranged in front of the front edge of the muffle. This position of the light source is a particularly exposed in terms of space-minimal design. In particular, this position is also with respect to thermal stress of the light source in comparison to other positions particularly uncritical. Additional measures, such as insulating materials or the like are not required here. In addition, it is also particularly protected from mechanical influences positionable here. In particular, in addition to the illumination of the cooking chamber, a particularly suitable information presentation that is simple and quick for the user is thus possible as well.

It is particularly preferably provided that the at least one light source is arranged between the front edge of the muffle and in a front view of the device in front of the front edge arranged trim strip of the cooking appliance. This is particularly advantageous in that the already existing space between the front edge and the front flange of the muffle and the trim strip is used accordingly. In particular, a carrier arranged therein is provided for receiving the light source. This allows a particularly mechanically stable positioning.

It can be provided that the light source is concealed from the trim strip when viewing the front of the device. This results in an advantageous embodiment in that, when introducing a food support quasi a shock protection for the light source is ensured. Damage can be avoided.

Preferably, the carrier is a metal part, which is strip-like or formed as a hollow profile. The at least one light source can thereby also be recessed in the carrier, whereby it is even more protected and improved in terms of space minimization improved. The thermal influence on the light source can be further reduced. In particular, the light source is arranged on a carrier connecting the front edge of the muffle and the trim strip. The carrier acts in such a configuration, as it were, as a mechanical connecting element between said components and is thus designed to be multifunctional. In addition to the inclusion of the light source, it is thus also provided as a mechanical stabilization and connection part.

In addition, it can be provided that the carrier is also formed at least one reflector for reflecting the light of the light source in the cooking chamber and / or in a door closing the cooking chamber. The light distribution and the visual information presentation can be further improved.

It when the light source is arranged so that it is arranged at a closed state of the cooking chamber closing door side of the door is particularly advantageous. As a result, additional space is required in view of the depth of the cooking appliance. In particular, thus the opening and closing of the door is ensured without restriction and the immediately adjacent light source is not affected in terms of mechanical stress or wear. Preferably, in particular when the cooking appliance is viewed from the front, the light source is arranged relative to the closed door such that in the depth direction of the door and thus in terms of its thickness, the light source is laterally disposed within the depth dimension of the door adjacent to that door. Since in this context usually seals are formed on the front muffle flange and the front edge, which seal the cooking chamber with the door closed, thus the light source is also formed practically in front of this seal. Precisely because a door of a cooking chamber is usually formed from a plurality of plates arranged one behind the other, in particular a glass material, thermal insulation to the outside is also achieved thereby. Due to this type of positioning of the light source, due to the design of the door, which according to an advantageous embodiment is likewise formed from at least two door glass plates in the form of a door inner pane and an outer door pane, a corresponding thermal insulation is achieved. Preferably, it is provided that the light source is covered by the door depth in the closed state of the door and the illumination of the cooking chamber is prevented. Preferably, it is provided in such an embodiment that the cooking appliance has a further lighting device, which is then provided in the closed state of the door for illuminating the cooking chamber and in particular individual insertion levels.

Advantageously, however, it can be provided that the door has a light-reflecting surface and in the closed state of the door, the light of the light source via the reflective surface in the cooking chamber for the illumination thereof can be introduced. In this case, a particularly specified advantageous embodiment is achieved in which this specifically arranged light source can also be used to illuminate the cooking chamber even when the door is closed. The reflective surface is preferably a flail arranged between a door inner pane and an outer door pane.

Preferably, the lighting device comprises at least two light sources, which are arranged one below the other so that they are each formed at least when the door of the cooking appliance open for illumination and / or display an associated Garraumebene and thus a rack level. In particular, in each case a light source, viewed in the vertical direction as it were, is arranged at the level at which the shelf level is also positioned at its height level. In an advantageous manner, it can be provided that the first light source for generating light is formed in a first visible spectral range for the human eye and the at least second light source for generating light in a different spectral range that is visible to the human from the first. Such a configuration also makes it possible to achieve a simple and color-identifiable illumination of individual insertion levels that can be recognized by a user at any time. A user, even if he is further away from the cooking appliance, at any time easily and quickly recognize which shelf level is illuminated and possibly occupied accordingly. Preferably, a light source is arranged so that when the door is open its light cone is at least partially directed forward and downward. The light cone is therefore also defined and directed forward out of the cooking appliance out. Partially pulled out or partially pushed in food carriers can therefore be fully illuminated.

Preferably, the light cone is at partially out of the oven to the front

protruding food support for lighting the top of the protruding part of the food support oriented.

Preferably, the at least one light source is arranged to be movable and dependent on an opening of the door and / or an at least partial withdrawal of the

Gargutträgers from the oven, the light cone is pivotable. This can be detected by sensors and controlled by a control unit. This allows a very precise and needs-based lighting done.

Preferably, it may also be provided that, in addition to a light source for illuminating the cooking chamber and / or for displaying information, at least one further

Light source is arranged adjacent to the first light source, wherein the light cone of the other light source is at least partially directed forward and downward with the door open and the other light source with the opening of the door and / or a pulling out of the food support from the cooking chamber can be activated. Thus, at least two light sources are formed next to each other, so that they are arranged practically on a plane. For example, this may be formed by an array of light-emitting diodes. When you take off the baking sheet, for example, then the other light source can be turned on and also partially illuminate the baking sheet partially pulled out.

In particular, the light source is a light emitting diode. This is particularly bright and energy-efficient operable and also very compact and small. However, since such light emitting diodes are relatively sensitive to temperature, an arrangement according to the invention or an advantageous embodiment is particularly suitable for this type of light sources. Further features of the invention will become apparent from the claims, the figures and the description of the figures. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or in the figures alone can be used not only in the respectively specified combination but also in other combinations or in isolation, without the scope of To leave invention.

Embodiments of the invention are explained in more detail below with reference to schematic drawings. Show it:

Fig. 1 is a schematic perspective view of an embodiment of a cooking appliance according to the invention;

2 is a perspective view of subcomponents of an embodiment of a cooking appliance according to the invention;

3 is a partial section of a cooking appliance when viewed from the front in accordance with a first specific mode of operation; and

Fig. 4 is a plan view of the illustration of FIG. 1 with additionally closed door of the cooking appliance.

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

In Fig. 1, a baking oven 1 is shown as a cooking appliance in a simplified perspective view. The oven 1 comprises a cooking chamber 2, in which food can be introduced for preparing. The cooking chamber 2 is bounded by a muffle 3, which comprises corresponding side walls 4 and 5, a ceiling 6, a bottom 7 and a rear wall 8. On the front side, a charging opening 9 is formed, which can be closed by a door 10. In the embodiment shown, the door 10 is hinged down and pivotable about a horizontal axis. It can also be provided be that the door 10 is hinged laterally and is pivotable about a vertical axis.

In addition, the oven 1 comprises an operating device 1 1, which is arranged only by way of example on the front side. The operating device 1 1 may have one or more operating elements and a display unit. In addition, the oven may also have cooking zones, not shown, on which preparation containers such as pots and pans and the like can be placed.

The oven 1 further comprises a lighting device 12, which is designed for illuminating the cooking chamber 2 and / or for displaying information for a user.

In Fig. 2 is a perspective view of some components of the oven 1 is shown, in addition, a horizontal section is formed in the x-z plane.

In the illustration according to FIG. 2, the door 10 is not shown. The muffle 3 has on the front side and to the boundary of the feed opening 9 on the circumference a front edge 13 or a muffle flange. At this front edge 13 is a circumferential seal

14 trained. Towards the front and thus in the x-direction in front of the front edge 13 is in a first vertical portion 13 a of the front edge 13 and front then to a second vertical portion 13 b of the front edge 13 each have a carrier 14 and

15 arranged.

Again in the extension in the x direction, a decorative strip 16 and 17 is arranged in front of the carriers 14 and 15.

When viewing the front of the oven 1, the decorative strip 16 is thus arranged immediately in front of the carrier 14 and this in front of the vertical section 13a of the front edge 14. The same applies to the arrangement of the carrier 15 with respect to the trim strip 17 and the vertical portion 13b. In particular, the carrier 14 is connected to the portion 13a on the one hand and the trim strip 16 on the other. The same applies to the carrier 15 with respect to the connection with the trim strip 17 and the section 13b.

In the carrier 14, a plurality of light sources 18a, 18b and 18c are arranged. These are designed as light-emitting diodes. The light sources 18a to 18c are thus arranged outside the cooking chamber 2 and thus positioned between the trim strip 16 and the portion 13a in front extension in front of the section 13a. In a corresponding manner 15 corresponding light sources are arranged in the carrier. The light sources 18a to 18c are designed to illuminate the cooking chamber 2 and in particular for illumination in each case of an associated insertion level and for displaying information. In particular, they are positioned so that they are concealed when viewed frontally of the oven 1 by the moldings 16 and 17.

The carrier 14 and 15 are designed in the embodiment as elongated at least partially hollow profiles. In addition to receiving the light sources 18a to 18c, they are also designed as receiving parts for reflectors. Thus, for example, the light of the light source 18a is formed via a reflector arranged in the carrier 14 in the direction of the cooking chamber 2 and in particular the insertion level assigned to this light source 18a and provided for the specific illumination.

By way of example, the light cone for illuminating a specific insertion level in the cooking chamber 2 is schematically indicated for the light source 18c. Likewise, another light cone of an opposite light source is sketched on the carrier 15. In Fig. 3 is a front view of a partial section of the oven 1 is shown. In this embodiment, three Gargutträger 19, 20 and 21 are inserted in different insertion levels in the cooking chamber 2. FIG. 3 also shows the fourth fourth light source 18d which is formed on this side and which is designed to illuminate the uppermost shelf level. On this top shelf level of the food support 19 is arranged.

It is provided that the light sources 18a to 18d are designed to generate specific light colors. In particular, it is provided that, for example at least one of the light sources 18a to 18d is designed to generate light in a spectral range which is visible to humans, which is different from a spectral range of one or more of the other light sources 18a to 18d. As a result, different illuminations of the individual insertion levels that are visible to humans can be generated.

Moreover, as shown in FIG. 3, provision may also be made for the lighting device 12 to be designed in such a way that optical displays can also be provided as information for the user in the carriers 14 and 15. According to the representation in FIG. 3, for example, a number can be visually displayed, which indicates the number of the associated insertion level.

The light sources 18a to 18d are thus arranged on the oven 1 that they are positioned in the area in front of the oven between the oven flange and the front surface of a trim strip.

According to a first embodiment can be provided that the illumination of the cooking chamber 2 and the individual insertion levels can be done only when the door 10 of the oven 1 is open. In particular, however, it is also provided that, even with the door 10 closed, a corresponding illumination of the cooking chamber or of the specific insertion levels with these light sources 18a to 18d can take place.

For further explanation in this regard, reference is made to FIG. 4. This shows a plan view of the illustration according to FIG. 2 and thus a viewing in the x-z plane. In addition, the door 10 is shown in the closed state. It is in this illustration again the series arrangement in the x-direction of the trim strip 16 and 17, the carrier 14 and 15 and the vertical portions 13a and 13b of the front edge 13 can be seen.

Furthermore, a reflector 22 in the carrier 14 is shown by way of example. By means of this, the light of the light source 18a is reflected from the carrier 14. With the door 10 closed, which has a thickness d, the light source 18a and the door 10 are positioned relative to one another such that the light source 18a is disposed laterally of the door 10 and in the depth direction, and thus in the x direction, between the depth dimensions of the door 10. This means that in the closed state of the door 10, this extends with its thickness d both forward and backward over the dimensions of the light source 18a. The same applies to the arrangement of the other light sources 18b to 18d and the light sources in the carrier 15th

The door 10 includes at least one door inner pane not marked in detail and a door outer pane arranged at a distance therefrom. In addition, there may also be more door washers.

In the door 10, a first mirror 23 is disposed adjacent to the light sources 18a to 18d. With this, the light emitted by the light source 18a light is reflected in the direction of the cooking chamber 2 and in particular for the illumination of the third insertion level. The same is achieved with a arranged on the opposite side mirror 24 with respect to an arranged in the carrier 15 illuminant.

Preferably, the light sources 18a to 18d are covered by light-transmissive elements disposed in recesses in the carrier 14 and the carrier 15. These transparent covers are identified in FIGS. 2 and 3 by reference numerals 25, 26, 27 and 28.

In FIGS. 2 to 4, embodiments are shown in which the light sources 18a to 18d illuminate into the cooking chamber 2. It can also be provided that, for example, the light source 18a is arranged pivotably and / or the reflector 22 is arranged pivotably. As a result, the light cone of the light source 18a can be changed in its orientation. Starting from the illustration in FIG. 4, it can then also be provided, for example, that with the door 10 open and partially pulled out of the cooking chamber 2, the area of the food support 20 projecting forward from the cooking chamber 2 can be illuminated on its upper side. The extraction can be detected by a corresponding sensor and the change in position of the light cone by a control by a control unit. In a further embodiment it can be provided that, adjacent to the light source 18a, a further, not shown, light source is arranged practically at the same height. Only when the door 10 is opened and the food support 20 is pulled out of the oven, this further light source is activated. It is then preferably arranged stationary and their light cone fixed, which then also illuminates the forward over the cooking chamber 2 projecting portion of the partially extracted food support 20.

Corresponding embodiments are then also provided for the light sources 18b to 18d.
