EP2550486B1 - Cooking appliance and method for operating a cooking appliance - Google Patents

Description

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 invention also relates to a method for operating a cooking appliance.

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 the 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.

The EP 2 119 967 A1 discloses a lighting with multiple light sources exclusively for the cooking chamber. The light of the light sources is conducted by means of light guides in the cooking chamber.

The WO 03/036176 A1 deals with the illumination of the cooking chamber exclusively, for which purpose the light of a light source arranged in the cooking appliance is deflected into the cooking chamber via a mirror arranged in a door.

The DE 20 2005 012027 U1 deals with the issue of process control of cooking in an oven.

It is an object of the present invention to provide a cooking appliance and a method in which the displaying and lighting of components is made more user-friendly and more extensive for a user in order to achieve situation-specific better perceptibility.

This object is achieved by a cooking appliance having the features of claim 1, and a method comprising the features of claim 19.

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 further includes a lighting device having at least a first light source. The lighting device comprises at least one first light source for illuminating the cooking chamber and for displaying information which is activated in at least one first operating mode of the cooking appliance and has at least one second light source which is activated in a different mode to the first second operating mode.

A beam of light is oriented with its main optical axis of an activated second light source in the cooking chamber at least partially forward from the oven and obliquely downwards. This is particularly advantageous when a component of the cooking appliance is to be illuminated, which protrudes in regions from the cooking chamber and is thus positioned projecting forward. Since conventional lights in a cooking appliance only illuminate the cooking chamber, it is therefore possible to illuminate the area that protrudes from the cooking chamber, especially in the case of a partially extended baking tray or the like.

Preferably, the at least one second light source is activated only in the second mode. As a result, the signalizing effect can be perceived particularly easily and the illumination of a component resulting therewith can be recognized particularly easily for a user.

Preferably, the at least one second light source is arranged directly adjacent to a first light source. A space-saving design is achieved. Furthermore, different lighting scenarios can then be performed virtually from one location, which the user intuitively perceives and easily recognizes in the different operating modes.

The second operating mode preferably comprises opening a door closing the cooking chamber and / or extracting the food support from the cooking chamber or a pyrolysis operation at least in regions. In particular, the second mode of operation is the opening of the door and / or the extraction of a food support from the cooking chamber. In particular, the second light source is open with the door and / or the Pull out automatically activated. The above advantages are enhanced.

Preferably, with the activation of the second light source, the automatic deactivation of the at least one first light source is coupled. This can be done directly with the activation of a second light source. However, it can also be provided that the deactivation of a first light source takes place only after a certain period of time, for example of a few seconds, has lapsed after activation of a second light source.

The first mode may be, for example, the running of a cooking program such as baking or cooking.

If there are a plurality of first and a plurality of second light sources, the deactivation of a specific first light source may depend on the activation of a specific second light source. This means that then also a first light source can remain activated and another first light source is deactivated. In particular, this may depend on the insertion level, in which a first light source is deactivated and a second light source is to be activated, so that, for example, other insertion levels are further illuminated by the associated first light source.

In particular, the cooking appliance comprises a control unit which is designed to control the activation and deactivation of the light sources.

The at least one second light source can be arranged in the muffle or outside the muffle.

It is preferably provided that, when the cooking appliance is viewed from the front, this first light source is positioned outside the cooking chamber and 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, she is also special here protected against mechanical influences. 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 also has at least one reflector for reflecting the light of the light source into the cooking chamber and / or into the cooking chamber closing door is formed. 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 this 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 at least when the door of the cooking appliance open for illumination and display of an associated Garraumebene and thus a shelf 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 oriented at partially protruding from the cooking chamber food support for illuminating the top of the protruding part of the food support.

Preferably, the at least one light source is arranged to be movable and, depending on the door being opened and / or at least partially pulled out of the food support from the cooking chamber, 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 can also be provided that, in addition to a light source for illuminating the cooking chamber and for displaying information, at least one further light source is arranged adjacent to the first light source, wherein the light cone of the further light source is directed at least partially 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.

In a method according to the invention for operating a cooking appliance with a cooking space which is bounded by walls of a muffle and which has a feed opening at the front, which is bounded on the circumference by a front edge of the muffle, and with a lighting device with at least one light source, the lighting device is provided with at least a first light source for illuminating the cooking chamber (2) and for displaying information, which in at least one first operating mode of the cooking appliance is activated, and formed with at least one second light source, which is activated in a first different second operating mode.

Advantageous embodiments of the cooking appliance according to the invention are to be regarded as advantageous embodiments of the method.

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

a plan view of the illustration according to 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 is shown in a simplified perspective view of a baking oven 1 as a cooking appliance. 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 that the door 10 is hinged laterally and is pivotable about a vertical axis.

In addition, the oven 1 comprises an operating device 11, which is arranged by way of example only on the front side. The operating device 11 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 shown a perspective view of some components of the oven 1, wherein in addition a horizontal section is formed in the xz-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, a circumferential seal 14 is formed. Towards the front and thus in the x-direction in front of the front edge 13, a carrier 14 and 15 is arranged in each case in a first vertical region 13a of the front edge 13 and then a second vertical section 13b of the front edge 13.

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 first 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.

Furthermore, each light source 18a to 18d immediately adjacent thereto has at least one second light source 29a to 29d. However, the light sources 29a to 29d may also be arranged inside the muffle 3. In particular, the first light sources 18a to 18d are activated in a first operating mode and the second light sources 29a to 29d are activated in a different second operating mode. If the modes of operation run at least simultaneously at times, at least one first and at least one second light source 18a to 18d or 29a to 29d can also be temporarily activated at the same time. If, for example, a cooking program is running, in particular at least one of the first light sources 18a to 18d has to be activated. If the door 10 is then opened while the cooking program is running and a food support is pulled out of the garraum 2 in regions, the second light source 29a to 29d is automatically activated for illuminating the food support from above in this insertion level. It can also be provided that with the opening of the door then the at least one first light source 18a to 18d is deactivated.

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 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. In Fig. 3 is still the fourth side of this light source 18d shown, which is designed to illuminate the top 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.

In addition, as shown in Fig. 3 Also be provided that the lighting device 12 is designed so that in the carriers 14 and 15 and visual displays can be made as information for the user. As shown in Fig. 3 For example, a number can be visually displayed, which indicates the number of the associated shelf 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 the related further explanation is on Fig. 4 directed. This shows a plan view of the illustration according to Fig. 2 and thus a consideration in the xz-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 in Fig. 2 and Fig. 3 recognizable by reference numerals 25, 26, 27 and 28.

In the Fig. 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 can then be provided, for example, that with the door 10 open and partially pulled out of the cooking chamber 2 Gargutträger 20 of the front of the cooking chamber 2 projecting portion of the food support 20 can be illuminated at its top. 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 first light source 18a, a further, not shown, at least one second light source 29a 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 set its light cone with the optical main axis fixed, the light cone then 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.
