Description

The invention relates to a heatable slide-in cooking space divider. The invention also relates to a cooking appliance, comprising a cooking chamber with a plurality of insertion levels, in each of which a slide-in cooking space divider can be inserted, each of the slide levels being associated with an electrical connection for an electrically operable slide-in cooking space divider.

Out DE 10 065 215 A1 a cooking appliance with a cooking space divider is known, which can be used in a cooking chamber of a cooking appliance muffle for dividing the cooking chamber. The cooking space divider has an electrically heatable radiator arrangement which is connected to a power supply when the cooking space divider is inserted. To cook food faster and more efficient, the radiator arrangement of the cooking compartment divider on a radiant heater, which is covered by a glass or glass ceramic cover plate of the cooking compartment divider. The glass or glass ceramic cover plate can serve as a storage area for a food container. In addition, protrudes from an end face of the housing, an electrical plug-in contact for serving as a radiator Bandheizleiter the cooking space divider. When used in the cooking chamber, the electrical plug contact for power supply with a plug connection to a rear wall of the Gargerätemuffel in combination. During operation of the cooking appliance with the cooking space divider inserted therein, a lower heating element arrangement is deactivated by a control device, not shown, of the cooking appliance. Instead, the inserted cooking chamber divider is supplied with electric current, so that the cooking chamber area is heated between a top heat radiation radiator arrangement and the cooking space divider.

It is the object of the present invention to at least partially overcome the disadvantages of the prior art and in particular to provide a possibility for a particularly energy-saving preparation of food.

This object is achieved according to the features of the independent claims. Preferred embodiments are in particular the dependent claims. The object is achieved by a heated drawer-cooking compartment divider, wherein an upper side of the drawer-Garraumteilers is designed as a Gargutaufnahme.

Under a slide-in cooking space divider can be understood in particular a cooking space divider, which can be arranged horizontally or horizontally in a cooking chamber of a cooking appliance. The drawer-Garraumteiler can be inserted for example in guides, which are located on the side walls of the cooking chamber. The drawer-Garraumteiler can alternatively be hung on an inner side of a cooking chamber door and then inserted by means of the cooking chamber door into the cooking chamber. By means of the use of the heated cooking space divider, a cooking space to be heated can be reduced, as a result of which an energy required for heating the cooking space can be reduced.

The fact that the top of the drawer-Garraumteilers is designed as a Gargutaufnahme, the food can therefore be placed directly on the top of the drawer-Garraumteilers improves, in contrast to a use of a Gargeschirrs the heat transfer. Consequently, the power consumption can be further reduced. The drawer cooking divider thus acts as a food support. Also, such a heated cooking space can be spatially better utilized. In addition, the degree of heat introduced by this insertion-cooking space divider or energy, in contrast to an unheated cooking space divider is substantially independent of a distance to a cooking chamber floor and in particular to a possibly there existing underheating.

It is an embodiment that the insertion-cooking chamber divider has a surface heating. Under a surface heating, in particular, a heater can be understood, which significantly heats a large part of the drawer-Garraumteilers. The surface heating may e.g. have a meandering shape.

It is an embodiment that the top of the drawer-Garraumteilers is designed trough-shaped and the surface heating is arranged on a bottom of the drawer-Garraumteilers. Due to the trough-shaped design, many kinds of food can be placed on the drawer divider without preparation. First, their contamination can be avoided by the underside arrangement of the surface heating as well as temperature peaks are reduced to the surface. The surface heating can in particular, heat a bottom of the trough-shaped area. It is a particularly space-saving and unobtainable development that the surface heating is a sheet resistance heating, for example with a thin-film heating or a thick-film heating.

It is still an embodiment that the insertion-cooking space divider has a temperature sensor, in particular a temperature sensor mounted on the underside. The temperature sensor may be electrically connected to the cooking appliance in a drawer divider inserted into the cooking compartment, e.g. via a suitable plug contact. By means of the temperature sensor, for example, a burning of an applied food can be avoided.

The object is also achieved by a cooking device having a cooking chamber with several insertion levels, in each of which a drawer-Garraumteiler is inserted, each of the insertion levels is associated with an electrical connection for an electrically operable drawer-Garraumteiler, wherein the cooking appliance is adapted to a Setting power entry at least in the slot-cooking compartment divider in dependence on a occupied by the drawer-cooking compartment divider shelf level. Thus, the power input and consequently a heating power of the cooking appliance can be automatically adjusted to the selected rack level, so that a user does not need to make this adjustment itself. Rather, a user can set, for example, a specified in a recipe setting for a bottom heat, without having to worry about the rack level of the drawer-Garraumteilers. This increases user-friendliness considerably. The cooking appliance can for this purpose have a control unit which can control the power input as a function of the shelf level.

It is also an embodiment that the cooking appliance is set up for a manual input of the rack level. As a result, a knowledge of the shelf level can be introduced into the cooking appliance with particularly simple means. The cooking appliance can in particular set up a user interface for entering the shelf level.

It is also an embodiment that the cooking device is set up for automatic detection of the rack level. This makes a particularly simple operation possible. The cooking appliance can for this purpose have a shelf level detection. This can detect, for example, a contacting of the electrical connections of the cooking appliance.

It is a development that the automatically detected rack level is manually confirmed, which increases operational safety and preparation safety.

It is still an embodiment that the cooking appliance is adapted to set a power entry in the drawer-Garraumteiler and in at least one other radiator, in particular Oberhitzeheizkörper, depending on a occupied by the drawer-Garraumteiler shelf level.

It is a further development that a bottom heat radiator present in the cooking appliance can be deactivated in the presence of the plug-in cooking chamber divider.

In an alternative embodiment, the cooking appliance no longer has a lower heat radiator. In this case, when a bottom heat is desired, always the slide-in cooking compartment divider must be inserted.

It is yet another embodiment that the cooking appliance is set up to run a program automatic, wherein by means of the program automatic a preferred insertion height depending on at least one of the cooking means to be cooked by the automatic program is determined. This allows a food to be cooked particularly energy-efficiently and gently.

The automatic program can be used, in particular, to automatically or semi-automatically prepare a specific food or meal with parameters stored in the appliance (for example cooking time, cooking temperature, selection of radiators, etc.) and with parameters entered by the user (weight, etc.). The automatic program can correspond to a recipe.

It is also an embodiment that by means of the program automatic a preferred insertion height depending on at least one of a user inputable parameters of the program automatic (eg type and / or amount of food to be treated) is determined. Thus, a particularly energy-efficient and appropriate preparation of the food can be achieved.

1. (a) automatisch von dem Gargerät in Abhängigkeit von der Einschubhöhe als einer Korrektur zu einer herkömmlichen Unterhitze und einer Einschubhöhe eines herkömmlichen Gargutträgers; und/oder
2. (b) automatisch von dem Gargerät in Abhängigkeit von einem bestimmten Gargut, insbesondere im Rahmen einer Programmautomatik. So kann die in den Oberhitzeheizkörper eingebrachte Leistung für ein hohes und sich somit näher an dem Oberhitzeheizkörper befindliches Gargut (z.B. ein ganzes Huhn) geringer eingestellt werden als für ein flaches Gargut (z.B. Huhn in Form von sog. 'Nuggets'). Diese Art des Garguts kann z.B. über die Programmautomatik abgefragt und/oder eingegeben werden;
   und/oder
3. (c) automatisch von dem Gargerät in Abhängigkeit von einem durch mindestens einen Temperatursensor des Einschub-Garraumteilers abgefühlten Temperaturwert; und/oder
4. (d) manuell. Durch die manuelle Einstellung kann entweder die in Schritt (a) oder (b) erfolgte Einstellung korrigiert werden und/oder das Verhältnis kann frei eingestellt werden, z.B. reichend von einer Leistungseinbringung nur in den (mindestens einen) Oberhitzeheizkörper bis hin zu einer Leistungseinbringung nur in den Einschub-Garraumteiler. Die manuelle Einstellbarkeit kann beispielsweise mittels eines dedizierten Bedienelements durchgeführt werden. Das Bedienelement kann beispielsweise körperlich ausgestaltet sein, z.B. als ein entsprechender Drehknopf, oder mittels eines berührungsempfindlichen Bildschirms gebildet werden, z.B. als ein sog. 'Slider' oder 'Zirkularslider'.

It is also an embodiment that on the cooking appliance (directly or indirectly), a ratio of a power input in the drawer-Garraumteiler and a power input is adjustable in a top heat radiator. This makes it particularly easy to set a browning of the food at its top and bottom. The ratio can be set, for example:

1. (a) automatically by the cooking appliance as a function of the shelf height as a correction to a conventional bottom heat and a shelf height of a conventional food support; and or
2. (B) automatically by the cooking appliance in response to a particular food, in particular in the context of a program automatic. Thus, the introduced into the upper heat radiator power for a high and thus closer to the upper heat radiator befindliches food (eg a whole chicken) can be set lower than for a flat food (eg chicken in the form of so-called 'nuggets'). This type of food can be queried and / or entered via the automatic program, for example;
   and or
3. (c) automatically by the cooking appliance in response to a sensed by at least one temperature sensor of the drawer-Garraumteilers temperature value; and or
4. (d) manually. By manual adjustment, either the adjustment made in step (a) or (b) can be corrected and / or the ratio can be freely adjusted, eg ranging from a power input only in the (at least one) top heat radiator up to a power input only in the slide-in cooking compartment divider. The manual adjustability can be performed, for example, by means of a dedicated control element. The control element can be embodied physically, for example as a corresponding rotary knob, or formed by means of a touch-sensitive screen, for example as a so-called 'slider' or 'circular slider'.

It is a further development that the cooking appliance, in particular in a setting automatically carried out by the cooking appliance, is adapted to change the ratio during a heating or cooking cycle (dynamic). Thus, for example, a turning of food to be reproduced and, for example, a food to be cooked on both sides without a turn 'grilled'.

In the following figure, the invention will be described schematically with reference to an embodiment schematically. In this case, the same or equivalent elements may be provided with the same reference numerals for clarity.

The figure shows a sectional view in side view of a cooking appliance in the form of a baking oven 1. The oven 1 has a cooking chamber 2, which is bounded by corresponding furnace walls 3 and front of an oven door 4. In the lateral furnace walls 3a guide rails 5 are for insertion u.a. of food carriers (o.Abb.) available. Laterally opposite guide rails 5 define a rack level.

In or on an upper furnace wall 3b is a Oberhitzeheizkörper 6, and in or on a bottom-side furnace wall 3c is a lower heat radiator 7. The upper heat radiator 6 and the lower heat radiator 7 are driven for their operation by a control unit 8, e.g. operated clocked.

In one, here: the middle, rack level is a slide-Garraumteiler 9. The drawer-Garraumteiler 9 divides the cooking chamber 2 into two approximately equal subspaces. The slide-in cooking space divider 9 has on its underside a meander-shaped surface heating 10 in the form of a resistance thick-film line. The slide-in cooking space divider 9 is thus an electrically operated cooking space divider.

To operate the surface heating 10, the slide-in cooking compartment divider 9 has an electrical plug-in element 11 on its edge adjacent to a rear oven wall 3d, which plug-in element can be plugged into an electric plug counter element 12 serving as an electrical connection in the rear oven wall 3d. The slide-in cooking chamber divider 9 can be supplied with electrical energy (current, voltage, etc.) via the electrical plug-in counter element 12, which can be controlled or regulated by means of the control unit 8. Each of the shelf levels is associated with its own electrical mating counter 12.

The slide-in cooking space divider 9 has on its upper side a trough-shaped Gargutaufnahme 13, in which to be treated food (o.Abb.) Can be directly placed or filled. The Gargutaufnahme 13 can be heated over a large area by means of the surface heating 10, so that in the Gargutaufnahme 13 befindliches food is directly heated by the drawer-Garraumteiler 9. This allows a particularly effective use of heat and is space-saving, so that the upper part space of the cooking chamber 2, which is bounded on the bottom side by the insertion cooking space divider 9, may be narrower in the case of a food that is housed in a separate vessel. In turn, energy can be saved.

The slide-in cooking compartment divider 9 also has a temperature sensor 14 on its lower side (alternatively: on its upper side). The temperature sensor 14 is communicatively coupled via the electrical plug-in element 11 and the electrical plug counter element 12 with the control unit 8. This allows the control unit to monitor, for example, a temperature at the drawer divider 9, e.g. for temperature control or as overheating protection, to prevent a food from burning or overcooking, etc.

The control unit 8 is set up to control a power input into the slide-in cooking chamber divider 9 and / or into the upper heat radiator 6 while the lower heat radiator 7 is switched off or deactivated in the case of a slide-in cooking compartment divider 9 inserted or inserted. The control unit 8 is due to a contacted by the plug-in element 11 plug counter 12 in a position to recognize occupied by the drawer-Garraumteiler 9 insertion level and to adjust following a power input into the drawer-Garraumteiler 9 and / or in the upper heat radiator 6.

Thus, with an occupancy of a higher insertion level and consequently a narrower upper subspace, an energy input for treating a food can be reduced overall compared to a larger upper subspace. Furthermore, since the contact heat transferred to the food to be cooked by means of the drawer divider 9 is substantially independent of the insertion height, the radiant heat generated by the upper heat radiator 6 is due to the distance changing with the shelf height can change the food to be cooked, the control unit 8 is also adapted to adjust a ratio of the power input in the drawer-Garraumteiler 9 and in the upper heat radiator 6 depending on the occupied shelf level. The ratio can be set directly as such or indirectly by setting the power settings accordingly.

The control unit 8 can also adjust the ratio of the power input in the drawer-Garraumteiler 9 and in the upper heat radiator 6 (directly or indirectly) depending on a type and / or quantity of the food, since a distance of the food to the upper heat radiator 6 also from the Type of food (eg a whole poultry or poultry pieces) and its quantity can depend.

Of course, the present invention is not limited to the embodiment shown.
