Description

The invention relates to a built-in cooking appliance according to the preamble of patent claim 1.

Various kitchen appliances, which can also be referred to as cooking appliances, are known for the preparation of foodstuffs, which can also be referred to as items to be treated or as items to be cooked. These include the hobs on which the food can be cooked in a cookware such as in a saucepan, with or without a lid, in a pan and the like by boiling, roasting and the like. For this purpose, the cooking utensil is placed on a hotplate of the hob and the bottom of the cooking vessel is heated electrically, inductively and the like by the hotplate. The cooking utensil can also be referred to as a cooking vessel, a support for the food to be cooked or a receptacle for the food to be cooked. In this case, the cooking utensil provides a cooking space for the food to be cooked, which in the case of pans and pots can be open or closed by means of a lid.

Cooking appliances are also known which have a cooking chamber which is formed immovably, i.e. fixedly, with the cooking appliance and in which the food to be cooked can be arranged in or on a cooking utensil and cooked with the cooking chamber of the cooking appliance closed. Such a cooking appliance can be, for example, an oven, a steamer, a microwave, a combination oven with a steamer and/or with a microwave, and the like. Such cooking appliances with a fixed cooking chamber usually have a height of about 45 cm in the vertical direction, at least in Germany, with ovens also having a height of about 60 cm being common.

Such cooking appliances with a fixed cooking chamber have in common that they have an outer housing as the outer housing, which essentially encloses the cooking appliance on the outside and protects its individual components and elements and makes them manageable together. An interior space is formed inside the cooking appliance, which represents the cooking chamber and is essentially enclosed by an inner housing as the inner housing, also known as the cooking chamber muffle or muffle. A housing space is formed as an intermediate space between the inner housing and the outer housing, in which functional elements of the cooking appliance such as a controller or a control unit, an electrical power supply and other components can be arranged which serve the intended use of the cooking appliance. In depth from the front, ie viewed from a user's point of view, the outer housing, the inner housing and a panel or a front panel together close the housing space, so that the housing space is not accessible to the user.

The interior of the cooking appliance has a through opening as an access opening at a depth to the front, through which the interior of the cooking appliance is accessible to the user, in order to insert cooking utensils into the interior of the cooking appliance as its cooking chamber and to arrange them there, and to remove cooking utensils after the treatment of the Remove food from the interior of the cooking appliance and remove it from there. The access opening can be opened by the user by means of a closure element, for example in the form of a laterally pivoting door, a downwardly pivoting flap and the like, in order to be able to access the interior of the cooking appliance, as described above, or to close the interior of the cooking appliance and to carry out the cooking process or the cooking process. Such a closure element can be closed or have a viewing window to allow the user to look into the closed interior of the cooking appliance.

Such cooking appliances with a fixed cooking chamber are usually designed as built-in appliances or as kitchen built-in appliances in order to be arranged in a space-saving manner and at a height that is easily accessible to the user in the vertical direction in kitchen furniture, such as in built-in cupboards in a kitchen, with their outer housing and with their locking element , If necessary. Additionally with their panel, see above, to the front towards the user to be flush with the surfaces of the other cooking appliances, drawers, doors and the like of the kitchen furniture, which can improve the visual impression for the user.

In addition to the cooking appliances with a fixed cooking chamber described above, these can also be combined vertically one above the other and/or horizontally next to each other with other built-in kitchen appliances such as warming drawers, vacuum mixing drawers and the like, which can also take on functions in the kitchen. Warming drawers are used, for example, to keep the cooked food warm without further cooking and to preheat dishes. In vacuum mixing drawers, food can be hermetically sealed in a vacuum in a package.

Such drawers as kitchen appliances are basically constructed in a similar way to the cooking appliances described above with a fixed cooking chamber, with drawers being designed to be significantly flatter, ie smaller in the vertical direction, and the user therefore has to be pulled out of the kitchen furniture towards the front to move in the vertical Direction from above to allow access to their interior. For this purpose, the movable part of the drawer, which can also be referred to as a pull-out, has a pull-out shelf, which serves to accommodate, for example, the cooking utensil in the vertical direction from above and can be moved in depth, for example, via rails arranged laterally in the transverse direction compared to the Inner housing of the drawer can be formed. The pull-out shelf usually has a vertically aligned panel in the depth towards the front, which closes the interior of the drawer or its access opening when closed.

Such drawers, also known as built-in drawers, usually have an overall height of about 14 cm in the vertical direction, at least in Germany. Drawers are usually arranged in the vertical direction below a cooking appliance with a fixed cooking space, such as below an oven, below a steamer and the like, or in combination with another drawer in the vertical direction one above the other, but can also be installed individually and independently in kitchen furniture . Since the installation spaces for built-in kitchen appliances in kitchen furniture, which can also be referred to as niches, usually have a vertical height of approx. 60 cm, at least in Germany, a drawer with an overall height of approx. 15 cm and a cooking appliance with a fixed cooking chamber can have approx. 45 cm height can be combined with each other as built-in devices.

The invention addresses the problem of providing a built-in cooking appliance so that a user can visually inspect the cooking chamber during operation and at the same time ensure safety, in particular protection of the environment and/or the user, and/or the visual impression for the user can be improved. At the very least, an alternative to known built-in cooking appliances of this type should be created.

According to the invention, this problem is solved by a built-in cooking appliance having the features of patent claim 1 . Advantageous refinements and developments of the invention result from the following dependent claims.

The invention thus relates to a built-in cooking appliance with an inner housing for accommodating at least one cooking chamber. A cooking space is understood to mean a receiving space in which an item to be cooked can be accommodated for cooking. A cooking chamber can be formed in particular by a cooking utensil and can be open or closed, as described above. A cooking utensil can be removed from the built-in cooking appliance. Such a cooking space can also be formed by a fixed component of the built-in cooking appliance.

The built-in cooking appliance has at least one heating device which is designed to heat at least the cooking chamber. This can be done, for example, by generating warm air, steam, inductively or by means of radiation, as will be described in more detail below. Each of these options for heating the cooking space can also be implemented by more than one heating device. Also can at least two of these options for heating the cooking chamber are provided in order to be used alternatively or simultaneously for cooking the food in the cooking chamber.

The built-in cooking appliance also has at least one first closure element, which is designed to close a through-opening in the inner housing, with the first closure element having at least one transparent window. The first closure element can thus be a door, a flap or the like, as previously known in, for example, ovens, microwaves, steam cookers and the like, so that a closed interior space can be formed, which accommodates the cooking space, so that the cooking operation can be carried out. Through the transparent window as a viewing window, the user can view the cooking chamber, check it visually and, if necessary, control the cooking process accordingly.

The built-in cooking appliance according to the invention is characterized by at least one second closure element, which is designed to at least essentially, preferably completely, cover the first closure element from the environment and at least essentially, preferably completely, to release it, the second closure element being movable independently of the first closure element . In other words, the built-in cooking appliance has at least two closure elements in the form of doors, flaps and the like, both of which can be moved relative to other elements of the built-in cooking appliance. The first closure element facing the cooking chamber serves to close the cooking chamber from the environment so that the cooking process can be carried out and to make it visible to the user through at least one transparent window. The second closure element, facing away from the cooking chamber, serves to cover the first closure element, which can be done in particular outside of operation. Furthermore, the first closure element can be released from the second closure element in order to move the first closure element and thereby make the cooking chamber accessible. Furthermore, in this way the transparent window of the first closure element can be released from the second closure element, so that the user can use the transparent window. For this purpose, the two closure elements can be moved independently of one another relative to one another or relative to other elements of the built-in cooking appliance, as will be described in greater detail below.

The present invention is based on the finding that the first closure element with a transparent window can allow the user to look inside the cooking chamber during operation of the built-in cooking appliance, ie during a cooking process, in order to assess the cooking process and, if necessary, change or stop the cooking process break up. Outside of the operation of the built-in cooking appliance, however, the sight of the first closure element with a transparent window are bothersome to the user. This can be due in particular to the fact that the first closure element with a transparent window is designed to meet the requirements of being able to withstand the heat or heat of a cooking process safely and permanently, which contradicts a visually appealing design of the first closure element with a transparent window user can stand. If the second closure element is therefore provided according to the invention, the second closure element can be designed to be more attractive to the user in terms of its visual design, which can improve the visual impression of the built-in cooking appliance for the user when not in use.

In particular, this can increase the scope for design with regard to the heat resistance of the first closure element with a transparent window, since less of its visual impression for the user needs to be taken into account. In particular, the heat resistance of the first closure element with a transparent window can be increased in this way in such a way that cooking processes can also be carried out inside the built-in cooking appliance at temperatures which are above the temperatures of, for example, previously known ovens and the like. In particular, cooking processes can be carried out with thermal radiation, which can reach particularly high temperatures, as will be described in more detail below.

This can be particularly advantageous in the case of built-in cooking appliances in the form of drawers, since the installation space of the first closure element, which is available for at least one transparent window, is particularly limited there.

According to one aspect of the invention, the first closure element and the second closure element are arranged one behind the other in the respective closed state from the perspective of a user. This can favor the fact that the first closure element, including the viewing window, can be covered as far as possible or completely by the second closure element in relation to the user. This can promote the corresponding properties and advantages described above.

According to a further aspect of the invention, the second closure element is opaque, preferably formed from a flame-retardant material. An opaque second closure element, for example made of metal, can favor covering the first closure element together with the transparent window and making it visually invisible to the user. At the same time, a visually appealing impression of the second closure element can be created for the user. Designing the second closure element to be flame-retardant can also increase safety.

According to a further aspect of the invention, the first closure element and the second closure element are designed to pivot purely in terms of rotation. This can be done, for example, via a hinge-like mechanical element or the like, which can form a pivot axis. This can keep the implementation of the purely rotary pivoting movement comparatively simple. Such a purely rotary pivoting movement can take place about an axis running in the horizontal as a pivoting axis downwards or upwards, as is usual, for example, with the flaps of ovens and the like. Such a purely rotary pivoting movement can alternatively take place around a vertical axis as the pivot axis to the left or to the right, viewed from the user's perspective, as is usual, for example, in doors of microwave ovens and the like.

In this case, the first closure element can be pivoted in the same direction or in the opposite direction as the second closure element. In other words, the pivot axes of both closure elements run horizontally, for example, with both closure elements being able to be pivoted downwards in the same direction. This applies correspondingly to pivoting upwards and to pivoting to the left or to the right about a vertical pivot axis. As a result, the two closure elements can be arranged directly one behind the other, which can promote a particularly compact design.

Alternatively, for example, one closure element can be pivoted horizontally downwards and the other pivoting element can be pivoted upwards in the opposite direction, which can increase the design options. For example, the second, outer closure element can be swiveled upwards and thereby form a screen, in order to divert vapors, which can escape, for example, through a vapor gap in the first, inner closure element, diagonally to the front and thus from the panel elements of other built-in cooking appliances or other kitchen furniture that are are in the vertical above the built-in cooking appliance according to the invention.

According to a further aspect of the invention, the second closure element is designed to be moved both in a translatory and in a pivoting manner. A translational movement is understood to mean a linear or rectilinear movement in one direction. A pivoting movement or a pivoting movement is understood to mean a movement about an axis or about a pivoting axis. Such a pivoting movement can be purely rotational, ie exactly in the circumferential direction around a pivot axis, as described above. However, such a pivoting movement can also take place in a combined rotational and translational manner in the form of an arcuate movement about a pivot axis. For this purpose, the translatory Movement and pivoting movement can be executed in a different order one after the other or combined with one another, which can increase the design options for the movements of the second, outer closure element.

According to a further aspect of the invention, the second closure element is designed to be moved in a combined rotational and translational pivoting manner. This can be done using appropriate mechanical elements. As a result, the possibilities of the pivoting movement can be increased. Such a movable second closure element can carry out movements as previously known from so-called lift screens. As a result, the second closure element can be moved away from the first closure element, in particular in the vertical direction upwards, with a comparatively small movement towards the user.

According to a further aspect of the invention, the first closure element is designed to form a vapor gap opposite the through-opening of the inner housing. In other words, the first closure element can be folded down slightly about a horizontal pivot axis and automatically remain in this position, so that a gap can be formed at the upper edge of the through-opening, through which vapors can escape from the interior or from the cooking chamber during the cooking process can escape to the outside of the built-in cooking appliance. Alternatively, at least one slot-like recess, preferably in the upper area and running horizontally, can be provided in the first closure element, which forms a vapor gap or a vapor slot. For this purpose, several smaller individual recesses can also be used, which together form the vapor gap. In any case, in this way vapors from the interior or from the cooking space can be automatically and specifically removed.

According to a further aspect of the invention, the first closure element has at least one display/operating element which is arranged outside the cooking chamber. As a result, corresponding display and/or operating options for the user can be provided on the first closure element facing him, which can also be released or covered by the second closure element, as described above.

Additionally or alternatively, the second closure element has at least one display/control element, which is arranged within the second closure element. In this way, corresponding display and/or operating options can be provided for the user on the second closure element, which can then be accessible to the user when the second closure element releases the first closure element. These display and/or operating options can be on the inside of the second closure element or on an edge of the second closure element be provided, which can offer good accessibility for the user in particular if the second closure element is designed to be pivotable downwards about a horizontal pivot axis. In any case, in this way the user can be given the opportunity to have information displayed by the built-in cooking appliance and to be able to make operator inputs.

According to a further aspect of the invention, the built-in cooking appliance has an extension which is designed to be moved in the longitudinal direction in an extension direction relative to the inner housing of the built-in appliance towards a user and in the longitudinal direction in an opposite insertion direction relative to the inner housing of the built-in appliance away from a user to be, wherein the cooking chamber and the first closure element with the drawer, preferably on a pull-out shelf of the drawer, is designed to be movable. In other words, the built-in cooking appliance can be designed in the form of a drawer, which can make it easier for the user to access the cooking space, since this can be partially or completely pulled out of the kitchen furniture towards the user and can be reached or removed in the vertical direction from above can. In this case, the first closure element can be moved translationally in the direction of insertion or in the direction of extraction and thereby close or open the passage opening of the inner housing. If necessary, the first closure element can also be pivotally provided on the pull-out, which can increase the design and usage options.

According to a further aspect of the invention, the first closure element of the pull-out is designed to form a closed interior of the built-in device with the inner housing of the built-in device when the pull-out is fully pushed in in the direction of insertion. As a result, the passage opening of the inner housing can be closed by means of the first closure element, as described above, if the built-in cooking appliance has a drawer that can be moved in translation.

According to a further aspect of the invention, the built-in cooking appliance has at least one first heating device, preferably an induction device, which is arranged in the vertical direction below the cooking chamber and is designed to heat at least the cooking chamber from below, preferably inductively, and the built-in cooking appliance has at least a second heating device, preferably a radiant device, particularly preferably a radiant heater with a heating strip, which is arranged in the vertical direction above the cooking chamber and is designed to heat at least the cooking chamber from above, preferably by means of radiation.

By using at least two heating devices, which can be of the same or different design with regard to their mode of operation, as before described, the flexibility in heating the cooking chamber can be increased. In particular, the power or the maximum temperature with which the cooking chamber can be heated can be increased.

Using an induction device as the first heating device can enable the user to carry out an inductively operated cooking process in the built-in cooking appliance according to the invention. For this purpose, the cooking utensil can be inductively heated in the vertical direction from below. A corresponding induction coil can only be as large as the base of the cooking utensil to be used. If necessary, several induction coils can also be used together to inductively heat the cookware.

Using a radiation device as the second heating device can make it possible to act directly on the cooking chamber with thermal radiation. A radiation device is to be understood as meaning a device which emits its power essentially through infrared radiators in the form of thermal radiation. Such a radiation device can also be referred to as a radiant heater or as a heat wave heater. This aspect of the invention is based on the finding that thermal radiation essentially does not heat the ambient air, which it penetrates, but only the cooking utensil or food to be cooked, on which the thermal radiation impinges. The cooking utensil or cooking item can thus be heated directly and as completely as possible by the heat radiation, in that the heat radiation reaches and heats the cooking utensil or cooking item. In other words, the heating by thermal radiation does not take place through the contact of the cooking utensil or the item to be cooked with the heated ambient air, as in the case of convection, but through the direct effect of electromagnetic waves or radiation in the infrared spectral range on the cooking utensil or item to be cooked.

According to the invention, the heating of the cooking utensil or the food to be cooked can be accelerated by both applying heat from below, preferably by means of induction, to heat the cooking utensil or its base and from above, preferably by means of thermal radiation, on the cooking utensil or directly the food to be cooked can take place in the case of a cooking utensil that is open at the top. On the other hand, this can also increase the degree of heating. This can in each case accelerate the cooking process, enable cooking with greater exposure to heat and/or achieve a more even cooking result.

Particularly preferably, the radiation device can have at least one radiant heater with a heating strip. The heating element in this case consists of a free-radiating corrugated heating strip which is arranged upright in the vertical direction and thus over the edge pointing downwards in the vertical direction Heat radiation in the direction of the interior of the built-in cooking appliance and thus the cooking utensil or the food to be cooked can emit. The heating strip is thus narrow in the horizontal and can therefore be surrounded by a comparatively thick thermal insulation, as a result of which the heat losses can be kept low. This can keep the warm-up time of the heating tape comparatively short.

According to a further aspect of the invention, the pull-out, preferably a pull-out shelf of the pull-out, has the first heating device. As a result, the first heating device and preferably the induction device can be arranged to move with the extension, so that the first heating device can be used and thus the cooking utensil is heated, preferably inductively, independently of the positioning of the extension. Accordingly, the preferably inductive cooking process does not have to be interrupted when a user pulls the pull-out out of the inner housing of the built-in cooking appliance in the pull-out direction, for example to examine the food in the cooking chamber directly. This can also allow the cooking process to continue undisturbed in this situation. For this purpose, the first heating device can remain connected to permanently arranged electronic components of the built-in cooking appliance, in particular via sufficiently long and flexible electrical connections.

According to a further aspect of the invention, the inner housing has the first heating device. In other words, the first heating device, preferably the induction device, is arranged in a fixed manner on the inner housing of the built-in cooking appliance and cannot be moved with the pull-out. As a result, the cooking utensil cannot be heated, preferably inductively, if the extension has been pulled out sufficiently far from the inner housing of the built-in cooking appliance. However, this can shorten and simplify the fixed electrical connection between the first heating device and the corresponding electronic components of the built-in appliance, which can reduce the manufacturing and assembly effort and thus keep the costs low.

According to a further aspect of the invention, a control unit of the built-in cooking appliance is designed to recognize a passage opening in the inner housing that is closed by the first closure element and to operate at least one of the two heating devices, preferably exactly the second heating device, only in this state. In other words, by means of a suitable sensor system, such as a button or an electrically disconnectable connection, the control unit can detect whether the passage opening of the inner housing is closed by the first closure element or not. If this is the case, a release to operate at least one heater or both heaters can be done because due to the recognized as closed interior of safe operation for the user and the environment can be assumed. This can be the case in particular if a second heating device and in particular a radiation device is present, which can reach a particularly high temperature of the cooking chamber.

According to a further aspect of the invention, a control unit of the built-in cooking appliance is designed to recognize a first closure element released by the second closure element and only operate at least one of the two heating devices, preferably precisely the second heating device, in this state. Comparable to what was previously described, it can be recognized in this way that the first closure element is released from the second closure element and the first closure element is therefore visible and accessible to the user. For safety reasons, this can additionally or alternatively be seen as a prerequisite for carrying out a cooking process.

According to a further aspect of the invention, the built-in cooking appliance has a width grid dimension with a width in the transverse direction. In this way, a comparatively compact arrangement of the built-in cooking appliance according to the invention in a piece of kitchen furniture can be made possible.

A width grid is to be understood that for the arrangement of fitted kitchen appliances in the width, i.e. in the transverse direction, the fitted kitchen appliances are dimensioned in the form of a grid so that different fitted kitchen appliances from the same manufacturer as well as from different manufacturers can be used seamlessly in combination with one another. In other words, certain dimensions in the width of fitted kitchen appliances are established as standard dimensions, i.e. customary and customary, or standardized, in order to be able to fully utilize the space in the kitchen furniture when combining different fitted kitchen appliances from the same manufacturer as well as from different manufacturers. These dimensions in the width of built-in kitchen appliances can be viewed as a grid.

For example, a standard width of 54 cm is common for fitted kitchen appliances in the European Union, so that the fitted kitchen appliance can be arranged between two 20 mm wide side walls of the kitchen furniture, also known as cleats, which itself has a width grid of 60 cm. In Switzerland, the width of built-in kitchen appliances is 55 cm. In the USA, a width grid of 18 inches, 24 inches or 36 inches is common for cabinets without built-in kitchen appliances. For built-in kitchen appliances, the grid dimensions including studs of the surrounding kitchen furniture of 24 inches and 30 inches have prevailed, although 36-inch wide ovens are also known, which, however, are usually not designed as fitted kitchen appliances.

According to a further aspect of the invention, the built-in cooking appliance has a height grid dimension in the vertical direction with a height of a built-in drawer which corresponds to a fraction of a width of a width grid dimension. This allows a particularly compact design of the built-in cooking appliance according to the invention. In this way, in particular, a simple possibility can be created of combining the built-in cooking appliance according to the invention with other standardized built-in cooking appliances one above the other in the vertical direction.

Comparable to the width grid dimension described above, a height grid dimension is to be understood as meaning that for the arrangement of fitted kitchen appliances in height, i.e. in the vertical direction, the fitted kitchen appliances are dimensioned in the form of a grid, so that different fitted kitchen appliances from the same manufacturer as well as different manufacturers can be seamlessly connected to one another can be used in combination. Dimensions or grids have become established as standard height dimensions, which are usually manufacturer-dependent, but are in the range of 6 cm to 10 cm and correspond to a fraction, i.e. divided by a natural number, of the width grid dimension.

Accordingly, it is common for fitted kitchen appliances in the European Union that the corresponding installation spaces of the kitchen furniture, also known as niches, have a height grid dimension of 15 cm, 45 cm or 60 cm, which, taking into account a floor with a thickness or a height of 10 mm or 20 mm, depending on the weight of the fitted kitchen appliance to be carried, leads to a height grid dimension of 14 cm, 43 cm or 58 cm of the fitted kitchen appliance itself. In the USA, the niche height for fitted kitchen appliances is usually 24 inches or 30 inches and 6 inches for drawers. Here, too, the height grid dimensions of the fitted kitchen appliances themselves, for example 5 3/8 inches for the drawers, are somewhat smaller than the height grid dimensions of the niche, so that the fitted kitchen appliances fit into the niches.

The height and width of a built-in kitchen appliance is always related to its housing, since a door, a flap, a panel and the like of the built-in kitchen appliance, which faces the user when installed, is usually larger in width and height than the Studs or on the floor of the kitchen furniture protrudes and this hides this optically from the user.

In other words, the invention is based on the finding that built-in drawers are limited in terms of height and space. While the drawer is in operation, the user should be able to observe, monitor and control the cooking process, despite the full integration of the device. Sufficient protection against the high heat during operation should be guaranteed. In the event of a grease fire, the cooking chamber may need to be secured so that it cannot be reached quickly, in order to prevent flames from escaping.

It is known that warming drawers have to be opened to operate them. It is also known that vacuum drawers have to be opened for service and operation. Built-in cooking appliances that have a door can be arranged behind a furniture front, which, however, does not belong to the built-in cooking appliance. For example, from the DE 10 2015 103 587 A1 a household appliance for installation behind at least one movable furniture front.

So far there are no built-in drawers known that can reach a similarly high temperature in the cooking chamber as with "normal" built-in cooking appliances. Such “normal” built-in cooking appliances are usually larger in size, which makes it easier for the user to observe, monitor and control the cooking process, since when the warming drawers are closed, it is not possible to observe the food being cooked.

According to the invention, a possibility should therefore be created to monitor the food to be cooked during operation, to control it and to control the device during the cooking process. The safety of the user should be guaranteed despite the high temperatures. Safety measures against flame formation should be initiated and the safety of the user should be guaranteed. It should also be possible to protect the furniture fronts, which can be particularly advantageous when the device is fully integrated.

According to the invention, a built-in cooking appliance is provided for this purpose, which has a first, inner door with a transparent window. This first inner door with viewing window must remain closed during the cooking process. A second, outer door or panel can then be opened to check and control the cooking process. When folding out the second, outer door, the controls should therefore be within reach of the user. These could be either on the inner door or on the outer panel, which are then accessed when flipped open. The outer panel does not have to be made of transparent material, such as stainless steel. possibly For safety reasons, switching on a radiant heater with a heating band when the outer door is closed could be prevented.

The inner door could have a vapor gap and the outer door or panel could be folded up and shield the vapor against kitchen furniture. This shielding of the vapors by the outer door could also be an advantage when the inner door is opened. The inner door could also be used when opening to possibly prevent liquids or dirt from escaping.

The outer door could be used for safety in case of flame formation and possibly coated with flame retardant material to ensure against flame spread to furniture.

The outer door could be designed as a lift panel. The outer panel could be raised and used for operation. The inner door can secure the access to the cooking space.

A built-in appliance can thus be made available which (below) can achieve contact heat and (above) high radiant heat in the cooking chamber. Nevertheless, there is the possibility of full integration into the furniture front or into the kitchen. A risk of burns for the user can be kept as low as possible. The cooking process can be monitored and controlled during operation despite the fully integrated device.

The built-in cooking appliance has a height with a standardized installation dimension. In particular, it is provided that the overall height is in a range that extends from 12 centimeters to 60 centimeters, preferably in a range from 14 centimeters to 35 centimeters.

The built-in cooking appliance 1 has an outer housing 10, which can also be referred to as the outer housing 10 and essentially closes off or encloses the built-in cooking appliance 1 on the outside. An inner housing 12 , which can also be referred to as the inner housing 12 , is arranged inside the outer housing 10 . The inner housing 12 closes in the longitudinal direction X to the front, i.e. from the perspective of a user, upwards and downwards in the vertical direction Z with the outer housing 10, so that an intermediate space (not shown) is formed between the outer housing 10 and the inner housing 12 is, which can also be referred to as the housing space. This intermediate space represents the interior of the built-in cooking appliance 1. The inner housing 12 also essentially encloses an interior space 11 in which a cooking process can be carried out. The interior 11 is accessible to a user in the longitudinal direction X from the front of the built-in cooking appliance 1 through a through-opening 13 as an access opening 13 .

A pull-out shelf 20 of the pull-out 2 is also arranged in the interior 11 and can be moved in the longitudinal direction X relative to the inside of the inner housing 12, for example by means of pull-out mechanisms 21, for example in the form of rail elements 21 or the like.

A first, inner closure element 23 and, on the other hand, a second, outer closure element 3 are arranged on the pull-out shelf 20, which extends horizontally X, Y. Both closure elements 23, 3 are each about a pivot axis (not labeled), which extends in the transverse direction Y and which are offset in the longitudinal direction X to one another by an angle of approximately 90° between the horizontal X, Y and the plane of the vertical direction Z and the transverse direction Y pivotable. Both closure elements 23, 3 can be pivoted independently of one another within this angle, with both closure elements 23, 3 being able to restrict the pivotability of one another.

Both closure elements 23, 3 are arranged directly one behind the other in the longitudinal direction X and the second, outer closure element 3 is formed, the first, inner closure element 23 in the longitudinal direction X, i. H. from a user's point of view, when both closure elements 23, 3 are arranged one on top of the other and folded up in the vertical direction Z. As a result, the first, inner closure element 23 can be hidden from the user by the second, outer closure element 3 .

The second, outer closure element 3, which can also be referred to as a cover 3, can have operating elements and/or display elements in order to give the user operating options and/or to display information. Such operating elements and/or display elements can be arranged on the outer edge of the second, outer closure element 3 or on its inside, facing away from the pivot axis.

In any case, the first, inner closure element 23 of the pull-out 2 can completely or partially release the through-opening 13 of the inner housing 12 for the user. For this purpose, the extension 2 can be moved in the longitudinal direction X in an extension direction A towards the user and in particular can be pulled by the user. In the direction opposite to the insertion direction B, the cover 3 of the pull-out 2 can be pushed or pressed away from the user and the through-opening 13 of the inner housing 12 can thereby be partially or completely closed. In this state, the interior 11 of the inner housing 12 corresponds to a pull-out space of the pull-out 2. For this purpose, the first, inner closure element 23 can be pivoted into the upright position, see for example figure 2 and 3 .

Irrespective of the position of the first, inner closure element 23, the second, outer closure element 3 can be swiveled down towards the user and the user can thus see and access the first, inner closure element 23, see FIG figure 3 . Possibly on the front of the first, inner Closure element 23 arranged controls and / or display elements can be optically detected by the user and used haptically. Furthermore, in this position of the second, outer closure element 3, the user can look into the interior 11 of the built-in cooking appliance 1 through two windows 24 of the first, inner closure element 23 and thereby visually observe, monitor and possibly influence a cooking process there.

In the vertical direction Z from above, the user can place at least one cooking utensil (not shown) on the pull-out shelf 20 of the pull-out 2 in a corresponding pulled-out position of the pull-out 2 . Corresponding markings and/or indentations or other holders (not shown) can be provided there for this purpose. The cooking utensil can also be referred to as a cooking vessel, a support for the food to be cooked or a receptacle for the food to be cooked. The cooking utensil consists of a cooking utensil housing, which can also be referred to as a cooking utensil body, and a cooking utensil closure, which can also be referred to as a cooking utensil cover. Each cooking utensil has a cooking space inside its cooking utensil housing, which the user can close by putting on the cooking utensil closure and opening or making accessible by lifting the cooking utensil closure.

To heat the cooking utensil or the food to be cooked from below, the built-in cooking appliance 1 according to the invention has a first heating device 22 in the form of an induction device 22 that can be moved in the vertical direction Z below the pull-out shelf 20 and with the pull-out 2 . In the area of the induction device 22, the pull-out shelf 20 is designed as a separating element in the form of a glass ceramic, on which the cooking utensil can be placed from above in the vertical direction Z. The induction device 22 has several induction coils in the horizontal X, Y, which almost completely cover the pull-out shelf 20, so that the pull-out shelf 20 can be used for inductively heating a correspondingly large and preferably square-shaped base of the cooking utensil.

To heat the cooking utensil or the food to be cooked, the built-in cooking appliance 1 according to the invention has a second heating device 14 in the form of a radiation device 14 in the vertical direction Z directly below the inner housing 12 and fixedly arranged on the inner housing 12 . The radiation device 14 is enclosed by a separating element in the form of a glass ceramic in such a way that the glass ceramic seals off the inner housing 12 in a gas-tight or vapor-tight manner, as a result of which all components and in particular all electronic components of the radiation device 14 are protected within the glass ceramic and thus from mechanical effects and from moisture can be arranged. Inside the glass ceramic is a radiant heater Heating strip arranged and aligned horizontally X, Y to emit thermal radiation in the infrared spectral range essentially in the vertical direction Z downwards into the interior 11 of the built-in cooking appliance 1 during operation. As a result, the cooking utensil or the item to be cooked can be acted upon in the vertical direction Z from above by means of heat radiation and this can be heated comparatively directly, quickly and/or with little loss.

According to the invention, the cooking utensil, which can fill the interior 11 of the built-in cooking appliance 1 at least in the horizontal X, Y as completely as possible, or the food to be cooked in the cooking utensil can be heated both inductively from below and by means of thermal radiation from above. This can speed up the cooking process, intensify it and/or make it more even.

Designing the built-in cooking appliance 1 as a drawer and arranging it in a piece of kitchen furniture can enable a particularly compact and space-saving implementation of the properties and advantages described above. This can be done in particular by means of a built-in cooking appliance 1 according to the invention, which has a normalized or standardized height in the vertical direction Z of 14 cm and a normalized or standardized width in the transverse direction Y of 54 cm. Comparable to a previously known warming drawer or the like, the built-in cooking appliance 1 according to the invention can thus be arranged in the vertical direction Z below an oven, for example, in order to be able to use the respective cooking options simultaneously and independently of one another. If the oven is designed with a comparatively small height of 43 cm in the vertical direction Z, the built-in cooking appliance 1 according to the invention and the known oven can be used together in a standardized furniture niche with a total height in the vertical direction Z of 58 cm and a Width in the transverse direction Y of 54 cm, in particular with a depth in the longitudinal direction X of 60 cm. This can enable users to provide or use extended cooking options than previously known in a comparatively small and standardized installation space, or known cooking options can be made available in a comparatively small space.

A particular advantage of the built-in cooking appliance 1 according to the invention is that the use of both the first, inner closure element 23 and the second, outer closure element 3 as a panel 3 can improve the visual impression for the user, since the first, inner Closure element 23 with its windows 24 can be hidden by the second, outer closure element 3 . The second, outer closure element 3 can be correspondingly visually appealing and, for example, uniform with the panels of other built-in cooking devices as well Pieces of furniture in the kitchen can be designed. Nevertheless, the functional first, inner closure element 23 can be used, which can serve in particular to close off the through-opening 13 and thus the interior 11 of the built-in cooking appliance 1 for carrying out the cooking process. In particular, the visual control of the cooking process by the user can be made possible by means of the window 24 of the first, inner closure element 23 .

The user's access options to the interior 11 of the built-in cooking appliance 1 can be increased in that the first, inner closing element 23 can not only be moved translationally with the pull-out shelf 20 in the longitudinal direction X, but there is also the possibility that the first, inner closing element 23 to pivot downwards, which can be done together with the second, outer closure element 3 or after the second, outer closure element 3 has been pivoted down.

According to the second exemplary embodiment, the second, outer closure element 3 is not arranged on the pull-out 2 but directly on the outer housing 10 of the built-in cooking appliance 1 about a pivot axis running in the transverse direction Y at the upper edge. The second, outer closure element 3 can be swiveled up through an angle of more than 90° and preferably at least 145°, so that a user can comfortably view and access the first, inner closure element 23 .

The first, inner closure element 23 has a plurality of slots running in the transverse direction Y on its upper edge, which together form a vapor gap 25 through which vapors can escape from the closed interior 11 of the built-in cooking appliance 1 to the outside. In this way, vapors can be discharged from the interior 11 of the built-in cooking appliance 1 to the outside during operation of the cooking process. The fumes can be diverted away from the built-in cooking appliance 1 by the inclined, second, outer closure element 3 .

figure 6 shows a representation of a built-in cooking appliance 1 according to the invention according to a third exemplary embodiment with the pull-out 2 pushed in and with the second closure element 3 swiveled up, viewed at an angle from above. In this case, the vapor gap 25 described above is formed by a gap that is formed between the upper edge of the first, inner closure element 23 and the upper edge of the through-opening 13 of the built-in cooking appliance 1 . For this purpose, the first, inner closure element 23 be held automatically in this position of about 5 ° to 10 ° relative to the plane of the transverse direction Y and the vertical direction Z.

figure 7 shows an illustration of a built-in cooking appliance 1 according to a fourth exemplary embodiment with the drawer 2 pushed in and with the second closure element 3 pivoted up, viewed at an angle from above. figure 8 shows the representation of the figure 7 with the second locking element swung down 3. figure 9 shows the representation of the figure 7 with partially extended drawer 2. figure 10 shows the representation of the figure 9 with the second locking element swung down 3.

In this case, the second, outer closure element 3 is attached to the outer housing 10 of the built-in cooking appliance 1 by means of a pivoting mechanism comparable to a lift panel, so that the second, outer closure element 3 can be moved essentially in the vertical direction Z upwards. This represents an alternative way of pivoting, which can allow for a comparatively compact movement.
