Description

Method for optically displaying a shelf level of a

Cooking appliance and cooking appliance

The invention relates to a method for optically displaying a shelf level of a food support in a cooking chamber of a cooking appliance, in which depending on a food to be cooked a preferred position in the cooking chamber is displayed.

Such methods and cooking appliances are already well known from the general state of the art and in particular from the Seriengargerätbau. For example, DE 10 2006 061 739 A1 discloses a muffle with walls delimiting a cooking chamber, on which support webs for attaching at least one food support are formed, and which has a lighting device, which for

Illumination is arranged from below and above the formed by the food support part spaces of the cooking chamber. Also, the document discloses

Method for illuminating a cooking chamber of a cooking appliance. For visual display of a subspace above a food support those Auflagestege shine on which the food support is not introduced, and which above that

Support webs are arranged on soft the food support is actually applied. DE 10 2009 003 136 A1 describes a cooking appliance with a muffle and a method for operating a cooking appliance. The muffle has on side walls support webs for a food support. In this case, the support webs are arranged in pairs so that different insertion levels are formed for the food support and optical display elements are arranged to display a shelf level on the muffle adjacent to the respective associated support webs. During an operating function of the cooking appliance while at least one preferred rack level is displayed, which by selecting the operating function by lighting the assigned

Display element is displayed. In this case, the operating function is functionally assigned to a specific lighting device of the cooking chamber and the automatic activation of the lighting device depends on the selection of the operating function. Displaying the shelf level in a cooking chamber for a food support is relatively imprecise and is therefore only partially user-friendly.

Object of the present invention is to provide a method and a cooking appliance in which a visual display of a rack level is specified.

This object is achieved by a method and a cooking appliance according to the independent claims.

In a method according to the invention, an insertion level for a food support in a cooking chamber of a cooking appliance is visually displayed. In order to introduce the food support in the cooking chamber of the cooking appliance Einschubbenen are formed. A

Shank level is formed in particular by supporting webs, which are arranged on a left vertical side wall and on a right vertical side wall of the cooking chamber. The support webs of a rack level are arranged in pairs opposite and the same altitude. Depending on the food to be cooked, a preferred position in the cooking space is displayed. An essential idea of the invention is that as the preferred position, that insertion level is optically displayed, on which the food support is to be applied directly to the food. For this purpose, at least one arranged on the cooking chamber side walls arranged support web, which is designed to support the food support and the shelf level itself, emits light.

It is provided that exactly that insertion level is visually displayed, which has been identified as the preferred position for the food to be cooked. There is a visual indication of the preferred position of the rack level even before the introduction of the food support instead, on which the food support to be applied directly to the food. In this case, light is preferably emitted by the support webs located on the left and right side walls, which are designed to support the food support and the insertion level on which the food support is to be actually applied. This light emission, serves for visual display of the shelf level, which has been identified as the preferred position for the food to be cooked. The support webs radiate to at least partially in terms of their dimensions, the light directly. As a result, the optical display of a Shelf level precise and visually precise. As a result, the intuitive understanding of a user is improved and incorrect positioning of a food support can be reduced.

In an advantageous embodiment of the method, the support web can radiate light in a first light color for optical display of the insertion level. It has proven to be particularly advantageous if the first light color is a signalizing or particularly attention-grabbing light color, in particular a red light color. For example, a red light color may prompt the operator to take action so that the intuitive operability can also be improved here.

It has also proven to be advantageous if, when a successful edition of the food support on the support web, the correct introduction to the correct

Shaft level and especially in a correct end position of the food support on the preferred rack level is visually confirmed. It becomes the user one

Feedback on a done action given, whereby a high level of security for the user can be guaranteed.

For example, different light colors can be selected on the one hand for displaying the preferred shelf level and on the other for confirming the correct position of the food support. It may be a first light color, in particular a red light color, can be used for optical representation of the insertion level, while confirming the correct placement of the food support on the preferred

Shutter level, for example, a white light color can be emitted. Also possible is an optical confirmation, which is visually displayed by means of a flashing signal as light emission of the support webs. For example, a short flash after the correct contact with the correct support bars can indicate to the user that the food support has been moved to the correct rack level. In addition to the short flashing but also other light signals are possible, for example, a change in light intensity. The entire possibilities can alternatively but also in

Be formed combination. In a further advantageous embodiment, for visual confirmation, at least one additional support web defining a further insertion level and arranged on a side wall delimiting the cooking chamber, which is designed to support a food support, emit light. In other words, after the introduction of the food support on the preferred rack level, another support web, in particular two other support webs, which are horizontally opposite in pairs and above the preferred shelf level, emit light. These embodiments also have the advantage that, on the one hand, the user can visually be shown in the simplest way the correct introduction of the food support and this can be reliably recognized by the user and thus also clearly understood.

Preferably, the blasting of the light, which indicates the correct movement of the food support is carried out optically, also at least in phases during a

subsequent preparation process of the food. As a result, the food to be cooked is illuminated on the food support during the cooking process, so that the user can easily inform himself about the preparation state of the food to be cooked by looking at the food.

It has also proven to be advantageous if the light emitted by the further support web light is emitted with a light emitted from the support web light different color. This means that the preferred support web, which forms the shelf level, radiates a different light color, as the other support web, in particular one of the overlying support webs, so for the user on the one hand, the preferred shelf level and on the other a lighting of the oven can be intuitively displayed ,

Furthermore, it has proven to be advantageous if the light of the support web is emitted as a light line. This has the advantage that not only the insertion level can be displayed to the user via a light point, but the preferred one

Shaft level over the entire three-dimensional space for the user is visible and a direction of insertion or a slide can be visually displayed. It has also proved to be advantageous if the type of food over a

Input device is specified, which communicates with a communication network

communicates, in particular with a so-called Home Connect network. In this communication network, in particular, a plurality of household appliances are networked with each other. For example, the home connect network can be an intelligent networking of many household appliances. By means of an application, for example on a mobile smartphone, can be communicated with the Home Connect network, so that the user can access the individual household appliances. The ability to connect the cooking appliance to the home-connect network has the advantage that the user can control the cooking appliance in the simplest way possible.

In a further advantageous embodiment, the type of food can be done via the selection of an automatic program of the cooking appliance. This means that, for example, via the input device, the user has a preparation program

can select which describes a specific preparation of a food, and thus the cooking appliance independently provides the corresponding parameter values, so that the user should bring only the food in the cooking chamber and a further control of the cooking appliance via the automatic program. Thus, the user can easily prepare a food by means of the cooking appliance. It has proven to be advantageous if the support web itself as a light guide

is provided and is emitted via the light guide light for displaying the rack level. The support bar is used multifunctionally, both as a carrier of the food support, as well as a light guide, which leads to a reduction of components. It can also be provided that the light guide is partially surrounded by a shell. This protects the optical fiber. The shell may be a tubular or channel-like component. The shell may also be a scratch resistant coating. The shell may also have holes through which the light guide can emit light. The invention also includes a cooking appliance with a cooking chamber through which walls of a

Muffel is limited, and with pairs on the same height positioned support webs, which are arranged on side walls of the muffle and which forms Einschubbenen for a food support. The cooking appliance is doing to perform a method one of the preceding claims. In particular, it comprises a control unit.

The terms "top", "bottom", "front", "rear", "horizontal", "vertical", etc. are intended to place the device when used and disposed of as intended and in front of the device and in the direction of the device Looking device

The muffle 3 is arranged in a housing 1 a of the cooking appliance 1 and the cooking chamber 2 is closed by a door 1 b, which is pivotally mounted on the housing 1 a. The muffle 3 comprises a ceiling wall, a bottom wall and a rear wall, and in particular vertically extending

Side walls 4, 5. At the cooking chamber 3 facing inner sides of the side walls 4, 5 support webs 6, 7, 8, 9, 10, 1 1 are arranged, which are in pairs at the same height, so that in the vertical direction a plurality of stacking levels arranged one above the other forms. These shelving levels make height nivus for one

Food support 15, so that this food support 15 can be horizontally placed in the cooking appliance 1. Each pair of opposite and located on the same height level support webs 6 to 1 1 define a shelf level.

With support webs 6, 7, 8, 9, 10, 1 1 can be non-variable editions. At least some support webs 6 to 1 1 can also be formed variable in length, for example, be telescopic extensions.

In FIG. 1, the food support 15 is introduced by way of example on a lower insertion level, which is defined by the support webs 6, 7.

In the embodiment, an input device 12 is located on the cooking appliance 1, by means of which, for example, an automatic program can be selected by the user, so that the type of the food can be entered via this input device 12 before preparation, so that a preferred one is automatically selected via the automatic program

Shelf level as well as the duration of the preparation and the temperature can be provided. This is controlled by a control unit of the cooking appliance 1, as is the entire procedure for visual indication of a shelf level. It can also be provided that the input device 12 is connected to a communication network 13, in particular a home-connect network, which can communicate with a plurality of other household appliances is networked. Thus, for example, with a mobile smartphone, which is also networked with the communication network 13, for example, a temperature or a running time of the cooking device 1 can be preset and / or the type of subsequent cooking food to be prepared can be entered.

In this embodiment, the shell 17 is formed of two grooves 17a, 17b, which surround the light guide 14 from above and below. However, the grooves 17a, 17b are arranged at a distance from each other, so that the light emitted by the light guide 14 can exit through the gap between the grooves 17a, 17b. In particular, a coherent light line is created here.

In FIG. 3, by way of example, at least one light source 16, for example a light-emitting diode, is shown. This is arranged outside the cooking chamber 2. Their emitted light couples into the light guide 14. In the method for optically displaying a shelf level of a food support 15 in a cooking chamber 2, in one embodiment, the input via an input device 12 first. For example, the user may use a smartphone to enter a food to be cooked. The input device communicates by means of a communication network 13 with the cooking appliance. The input can be made in particular via an automatic program, so that, for example, after entering the type of food to be cooked, the automatic program presets a cooking process, in particular a cooking duration and a temperature control, automatically.

After entering the food can be displayed in the cooking chamber in a next step, the preferred position for the food support 15, which is dependent on the food to be cooked. As a preferred position that insertion level is visually displayed on which the food support 15 is to be applied directly to the food by, for example, two of the support webs 6 to 1 1, which form the preferred shelf level, even emit light. In the embodiment in Fig. 1 then light up the support webs 6 and 7, when the lowest insertion level, which is formed by the support webs 6 and 7, the preferred. In particular, the support webs 6 and 7 emit light, for example in a red light color. The user is displayed before the introduction of the food support 15, in soft position he has to hang the food support 15.

In a next step, the introduction of the food support 15 is carried out with the food to be cooked on the preferred rack level. In Fig. 1, the food support 15 is shown in the already introduced state on the support webs 6 and 7. After the food support 15 has been introduced correctly, in particular to the correct

Shank level and in particular in the correct end position on this rack level, preferably a confirmation of the correct introduction can take place. In this embodiment, the confirmation is optically via a light emitting,

in particular a white light beam. The visual confirmation takes place in such a way that light emission takes place from at least one other support web 8, 9, 10, 11. In particular, a blasting of an acknowledgment light is carried out by a further support web 8 to 11 located above the support webs 6 and 7 in the height direction. In particular, it is provided that initially one of the two support webs 8, 9 lights up for confirmation, in the height direction next on the support webs. 6 and 7 follows. The same applies, in particular, if, for example, a preferred insertion level is given by the support webs 8 and 9, so that then in particular at first one of the support webs 10, 1 1 disposed above an optical

Confirmation signal generated. If the preferred shelf level for a food to be cooked is the top shelf level, defined here by the support webs 10 and 11, then it can also be provided here that for the optical confirmation of the correct position of the food support 15, first one of the two support webs 8, 9 arranged directly underneath shines.
