Description

[0001] The invention relates to a system comprising a piece of furniture with a built-in niche and a built-in appliance of the type mentioned in the preamble of patent claim 1 and a method for operating the system.

[0002] Such systems and methods for their operation are already known from the prior art in a large number of embodiments, for example from the document DE 75 19 943 U. The known systems comprise, for example, a piece of furniture with a built-in niche formed in a furniture body of the furniture with a built-in niche opening, a built-in appliance for preparing food arranged in the built-in niche and a storage device with a storage space arranged below the built-in appliance in the built-in niche and a storage mechanism, wherein the built-in appliance arranged in the built-in niche is inaccessible by means of a furniture door of the furniture in a closed position of the furniture door covering the built-in niche and accessible in an open position of the furniture door,and wherein the storage space is designed to accommodate the furniture door in its open position and the storage mechanism is designed, on the one hand, to transfer the furniture door from its closed position to its open position and from its open position to its closed position and, on the other hand, has longitudinal guides arranged on the furniture body and / or on the built-in appliance on both sides of the furniture door and rotatably arranged guide rollers on the furniture door corresponding to the longitudinal guides.

[0003] Furniture doors which can be inserted into a furniture body are known from the documents IT MI20 110 131 A1 and US 1 115 345 A as well as GB 398 619 A.

[0004] From the document DE 27 45 788 A1, a cooking appliance is known which has a receiving space in the lower housing area into which an appliance door can be inserted. The document DE 199 06 913 A1 also shows a device for translationally moving the appliance door of a cooking appliance in a horizontal plane.

[0005] The invention therefore addresses the problem of improving a system comprising a piece of furniture with a built-in niche and a built-in appliance, and a method for operating the system.

[0006] According to the invention, this problem is solved by a system having the features of patent claim 1, which is characterized in that at least two of the longitudinal guides are mounted on the furniture body and / or the built-in appliance in a manner corresponding to each other and on opposite sides of the furniture door, such that they are movable or automatically movable, such that the furniture door can be moved back and forth between its closed position and its open position relative to the furniture body and the built-in appliance without collision. Furthermore, this problem is solved by a method having the features of patent claim 9.

[0007] The built-in appliance for preparing food can be designed, for example, as an oven, a microwave, a steamer, a combination cooking appliance with a variety of different heating methods, or a coffee machine. However, the above list is purely exemplary and not restrictive. Furthermore, the built-in appliance can be designed as a household appliance or a commercial appliance, i.e., a built-in appliance for professional use. Advantageous embodiments and further developments of the invention are set out in the following subclaims.

[0008] The advantage achievable with the invention lies in the fact that a system comprising a piece of furniture with a built-in niche and a built-in appliance, and a method for operating the system are improved. Due to the inventive design of the system and the method, it is possible for the furniture door to be transferred back and forth relative to the furniture body and the built-in appliance between its closed position and its open position without collision. The longitudinal guides, which are held movably or automatically on the furniture body and / or the built-in appliance, enable a pivoting movement of the furniture door when transferring the furniture door from its open position to its closed position or vice versa, almost without the translational movement usually associated with a furniture door pivoting about a rotation axis.Accordingly, an unwanted collision of the furniture door when it is transferred from its open position to its closed position or from its closed position to its open position with the furniture body on the one hand and with the built-in appliance on the other hand is effectively prevented.

[0009] In principle, the system can be freely selected within wide, suitable limits in terms of type, mode of operation, material, and dimensions. An advantageous development of the system according to the invention provides that the adjustment mechanism is designed such that the longitudinal guides automatically mounted on the furniture body and / or the built-in appliance and / or the corresponding guide rollers can be moved automatically in response to a closing command and / or opening command for the furniture door applied to the adjustment mechanism. In this way, the user-friendliness of the system according to the invention is significantly increased. Manual operation of the furniture door when transferring it from its closed position to its open position and vice versa is no longer necessary. A user of the system therefore has their hands free for other activities, for example.Furthermore, the adjustment mechanism can be controlled by a plurality of closing and / or opening commands from different devices. These devices can be, for example, the built-in appliance installed in the installation niche. For example, the closing and / or opening command can be triggered by the built-in appliance depending on a predetermined operating state of the built-in appliance and / or a predetermined automatic program running in the built-in appliance. However, it is also conceivable that the closing and / or opening command to the storage mechanism can be triggered by a mobile device, such as a smartphone or the like.

[0010] In the system according to the invention, it is provided that four longitudinal guides are held on the furniture body and / or the built-in appliance and four guide rollers are held on the furniture door, wherein each of the four guide rollers corresponds to one of the longitudinal guides, and wherein two of the four longitudinal guides are arranged on either side of the furniture door in such a way that the two longitudinal guides arranged on one of the two sides are arranged one above the other and spaced from one another, preferably that the two guide rollers arranged on one of the two sides are arranged at a constant distance on the furniture door regardless of the position of the furniture door to one another, particularly preferably that these guide rollers are each arranged on the furniture door at a constant distance from an inner side of the furniture door.As a result, the system according to the invention, in particular the stowage mechanism of the system according to the invention, can be implemented in a structurally and technically robust and functionally reliable manner. This applies particularly to the preferred and, in particular, to the particularly preferred embodiment of this development. For example, the aforementioned spacing of the guide rollers enables a sufficiently long lever arm to absorb the weight of the furniture door acting in the open position of the furniture door, i.e., in its horizontal position, by means of the stowage mechanism without additional aids such as Teflon glides or the like.

[0011] An advantageous refinement of the aforementioned refinement of the system according to the invention provides that the longitudinal guides arranged at the top on both sides are designed as the longitudinal guides movably or automatically held on the furniture body and / or the built-in appliance. Preferably, only the two aforementioned longitudinal guides are designed as the longitudinal guides movably or automatically held on the furniture body and / or the built-in appliance. In this way, the structural and manufacturing design of the system according to the invention is further simplified. This applies in particular to the preferred embodiment of this refinement.

[0012] An advantageous development of the last two embodiments of the system according to the invention provides that the longitudinal guides arranged at the top on both sides have a horizontally extending first section, far from the installation niche opening, and a second section, near the installation niche opening, extending transversely upwards, preferably vertically upwards, to the first section. The first and second sections are connected to one another by means of a transition section of the respective longitudinal guides, guiding rollers. As a result, the longitudinal guides arranged at the top on both sides of the furniture door are implemented in a robust and thus functionally reliable manner according to one of the last two embodiments of the system according to the invention.

[0013] An advantageous development of the system according to the invention according to one of claims 4 or 5 provides that the longitudinal guides arranged at the bottom on both sides have a horizontally running first section far from the installation niche opening and a second section close to the installation niche opening running transversely downwards to the first section, preferably in a downward curve, wherein the first and the second section are connected to one another by means of a transition section of the respective longitudinal guide in a guide roller-guiding manner, preferably that the transition section, starting from the first section, initially transitions continuously upwards to a vertex and then continuously downwards from the vertex into the second section.In this way, the longitudinal guides arranged at the bottom on both sides of the furniture door according to one of the last three embodiments of the system according to the invention are also implemented in a robust and therefore functionally reliable manner. A particularly advantageous development of the system according to the invention provides that the guide rollers are each arranged on the furniture door in such a way that the overall width of the furniture door remains constant regardless of the presence of the guide rollers on the furniture door. This makes it possible for the system according to the invention to be advantageously used even with furniture and built-in appliances with standard dimensions. It is therefore not necessary, for example, to design and manufacture the furniture body and / or the built-in appliance inserted into the installation niche of the furniture body deviating from standardized dimensions.The application of the system according to the invention is also simplified accordingly, since the system according to this development is designed to match the standard dimensions commonly used for furniture with built-in niches and built-in appliances for such built-in niches. Thus, the system according to the present development is also suitable for subsequent conversion, i.e., as a retrofit kit.

[0014] Analogous to the aforementioned development of the system according to the invention, another advantageous development of the system according to the invention provides that the storage mechanism and the furniture door are designed to be coordinated with one another in such a way that the depth of the built-in niche is constant regardless of the presence of the storage space arranged beneath the built-in appliance and the furniture door arranged in this storage space in the open position. In this way, the design of the depth of the built-in niche is minimized; in particular, the depth of the built-in niche does not have to extend beyond the dimension of the furniture door in the open position, or only by a few centimeters. It is even possible that a depth of the built-in niche deviating from the usual standard dimensions is not required for the system according to the invention. See also the advantages mentioned for the aforementioned embodiment of the system according to the invention.

[0015] A further advantageous development of the system according to the invention provides that the storage mechanism is designed such that the longitudinal guides, which are movably or automatically mounted on the furniture body and / or the built-in appliance, can be moved horizontally in the direction of the built-in niche opening when the furniture door is transferred from its closed position to its open position, and horizontally in the direction opposite to the direction of the built-in niche opening when the furniture door is transferred from its open position to its closed position. This enables a simple movement sequence for the longitudinal guides, which are movably or automatically mounted on the furniture body and / or the built-in appliance, so that these longitudinal guides are implemented in a particularly simple manner in terms of design and manufacturing technology.Due to the simple movement sequence, for example, undesired tilting or jamming during the movement of the aforementioned longitudinal guides is effectively prevented, so that the robustness and functional reliability of the system according to the invention are further improved according to this development.

[0016] The direction of the built-in niche opening is defined as from the rear wall of the furniture to the front of the furniture. According to one aspect, the direction of the built-in niche opening is oriented orthogonally to the plane of the furniture front or to the plane of the furniture door in the closed position.

[0017] Accordingly, an advantageous development of the method according to the invention provides that the longitudinal guides held movably or automatically on the furniture body and / or the built-in appliance are moved horizontally in the direction of the installation niche opening when the furniture door is transferred from its closed position to its open position and horizontally in the direction opposite to the direction of the installation niche opening when the furniture door is transferred from its open position to its closed position.

[0018] A further advantageous development of the method according to the invention provides that the furniture door, when being transferred from its closed position to its open position by means of the adjustment mechanism, is firstly pivoted about a rotation axis of the furniture door and simultaneously lifted upwards in a first movement section of the furniture door by moving the longitudinal guides, which are held movably or automatically on the furniture body and / or the built-in appliance, in the direction of the built-in niche opening, and secondly, in a second movement section of the furniture door, which directly follows the first movement section in time, by moving the longitudinal guides, which are held movably or automatically on the furniture body and / or the built-in appliance, in the direction opposite to the direction of the built-in niche opening, is pushed horizontally into the storage space.In this way, the overall movement of the furniture door of the system according to the invention is divided into functionally separate movement sections when transferring it to its open position. Accordingly, each of the two movement sections can be configured in a predetermined manner for its function, thus significantly simplifying the design of the adjustment mechanism. The same applies to the transfer of the furniture door from its open position to its closed position. However, for this purpose, the aforementioned movement sections are executed in reverse order.

[0019] An embodiment of the invention is shown purely schematically in the drawings and is described in more detail below. It shows Figure 1 shows an embodiment of the system according to the invention for carrying out the method according to the invention in a front view, with the furniture door in its closed position, Figure 2 shows the embodiment in a partial, sectional side view, with the furniture door in its closed position, Figure 3 shows the embodiment in a partial, sectional side view, with the furniture door in a first intermediate position, Figure 4 shows the embodiment in a partial, sectional side view, with the furniture door in a second intermediate position, Figure 5 shows the embodiment in a partial, sectional side view, with the furniture door in a third intermediate position, Figure 6 shows the embodiment in a partial, sectional side view, with the furniture door in a fourth intermediate position, Figure 7 shows the embodiment in a partial, sectional side view, with the furniture door in a fifth intermediate position, Figure 8 shows the embodiment in a partial,sectional side view, with the furniture door in a sixth intermediate position, Figure 9 the embodiment in a partial, sectional side view, with the furniture door in its open position and Figure 10 the embodiment in a partial, sectional side view, with the furniture door in its open position, with a movement track of the guide roller guided in the upper longitudinal guide. ,

[0020] In the Fig. 1 to 10 An embodiment of the system according to the invention for carrying out the method according to the invention is shown purely by way of example.

[0021] The system 2 comprises a piece of furniture 4 designed as a kitchen furniture with a built-in niche 8 formed in a furniture body 6 of the furniture 4 with a built-in niche opening 10, a built-in appliance 12 arranged in the built-in niche 8 and designed as an oven for preparing food and a stowage device 14 with a stowage space 16 arranged below the built-in appliance 12 in the built-in niche 8 and a stowage mechanism 18, wherein the built-in appliance 12 arranged in the built-in niche 8 can be stowed away by means of a furniture door 20 of the furniture 4 in a recess covering the built-in niche 8 and extending into the Fig. 1 and 2 shown closed position of the furniture door 20 and in a position in the Figs. 9 and 10 shown opening position of the furniture door 20, and wherein the storage space 16 is designed to accommodate the furniture door 20 in its opening position.

[0022] The stowage mechanism 18 is designed, on the one hand, to transfer the furniture door 20 from its closed position to its open position and from its open position to its closed position. On the other hand, the stowage mechanism 18 comprises longitudinal guides 22, 24 arranged on the built-in device 12 on both sides of the furniture door 20 and rotatably arranged guide rollers 26, 28 arranged on the furniture door 20 corresponding to the longitudinal guides 22, 24. Fig. 2 to 10 Only two of the four longitudinal guides 22, 24 and only two of the four guide rollers 26, 28 are visible, namely the guide rollers 26, 28 corresponding to the two visible longitudinal guides 22, 24. The visible longitudinal guides 22, 24 are shown in the Fig. 2 to 10 symbolized by dashed lines. The corresponding guide rollers 26, 28 and their mounting on the furniture door 20 are shown in the Fig. 2 to 10Also shown in a highly simplified manner for clarity. The invisible longitudinal guides and guide rollers on the other side of the built-in appliance 12 and the furniture door 20 are designed and arranged in a similar manner to the visible longitudinal guides 22, 24 and guide rollers 26, 28.

[0023] According to the invention, two of the longitudinal guides 22, 24, namely the longitudinal guides 22, are held on the built-in appliance 12 in a corresponding manner and on opposite sides of the furniture door 20 in such a way that the furniture door 20 can be moved back and forth between its closed position and its open position relative to the furniture body 6 and the built-in appliance 12 without collision. The adjustment mechanism 18 is designed such that the longitudinal guides 22, which are held automatically on the built-in appliance 12, and the corresponding guide rollers 26 are automatically movable depending on a closing command and / or opening command of the furniture door 20 applied to the adjustment mechanism 18.

[0024] Thus, four longitudinal guides 22, 24 are held on the built-in appliance 12 and four guide rollers 26, 28 are held on the furniture door 20, wherein each of the four guide rollers 26, 28 corresponds to one of the longitudinal guides 22, 24, and wherein two of the four longitudinal guides 22, 24 are arranged on either side of the furniture door 20 such that the two longitudinal guides 22, 24 arranged on one of the two sides are arranged one above the other and spaced from one another, namely such that the two guide rollers 26, 28 arranged on one of the two sides are arranged at a constant distance on the furniture door 20, regardless of the position of the furniture door 20 relative to one another. Furthermore, these guide rollers 26, 28 are each arranged on the furniture door 20 at a constant distance from an inner side of the furniture door 20.Furthermore, the guide rollers 26, 28 are each arranged on the furniture door 20 in such a way that the overall width of the furniture door 20 remains constant regardless of the presence of the guide rollers 26, 28 on the furniture door 20. Accordingly, the overall width of the furniture door 20 does not change due to the presence of the guide rollers 26, 28 compared to the overall width of the furniture door 20 without the guide rollers 26, 28. The overall width of the furniture door 20 runs perpendicular to the image plane of the . Fig. 2 .

[0025] In the present exemplary embodiment, only the longitudinal guides 22 arranged at the top on both sides are designed as the longitudinal guides 22 automatically movable on the built-in appliance 12. These longitudinal guides 22 arranged at the top on both sides have a horizontally extending first section 30 far from the installation niche opening and a second section 32 close to the installation niche opening extending transversely upwards, namely vertically upwards, to the first section 30, wherein the first and second sections 30, 32 are connected to one another by means of a transition section 34 of the respective longitudinal guide 22 in a guide roller-guiding manner.

[0026] In contrast, the longitudinal guides 24 arranged at the bottom on both sides are immovably, i.e., fixedly, held on the built-in appliance 12. These longitudinal guides 24 arranged at the bottom on both sides have a horizontally extending first section 36 far from the installation niche opening and a second section 38 close to the installation niche opening, which runs transversely downwards to the first section 36, namely in a downward curve, wherein the first and second sections 36, 38 are connected to one another by means of a transition section 40 of the respective longitudinal guide 24 by guide rollers. In the present exemplary embodiment, the transition section 40 is designed such that the transition section 40, starting from the first section 36, initially transitions continuously upwards to a vertex and then continuously downwards from the vertex into the second section 38.

[0027] The storage mechanism 18 and the furniture door 20 are designed to be coordinated with one another in such a way that the depth of the built-in niche 8 is constant regardless of the presence of the storage space 16 arranged beneath the built-in appliance 12 and the furniture door 20 arranged in this storage space 16 in the open position. Accordingly, the presence of the storage device 14 requires a depth of the built-in niche 8 that is not greater, or only a few centimeters greater, than the depth of the furniture door in the open position. The depth of the built-in niche 8 runs in the image plane of the Fig. 2 horizontal.

[0028] The storage mechanism 18 is further configured such that the longitudinal guides 22, which are automatically movable on the built-in appliance 12, can be moved horizontally in the direction of the built-in niche opening 10 when the furniture door 20 is moved from its closed position to its open position, and horizontally in the direction opposite to the direction of the built-in niche opening 10 when the furniture door 20 is moved from its open position to its closed position. This will be explained in more detail below.

[0029] The functioning of the system according to the invention and the method according to the invention according to the present embodiment are described below with reference to Fig. 1 to 10 explained in more detail.

[0030] First, the furniture door 20 of the system 2 is in its Fig. 1 and 2shown closed position. In this closed position, the furniture door 20 covers the built-in niche opening 10 and thus the built-in niche 8. On the other hand, the furniture door 20 in its closed position prevents access to the built-in appliance 12 located in the built-in niche 8. In the closed position of the furniture door 20, the furniture door 20 forms a joint pattern with a remainder of the furniture 4 in the horizontal and vertical direction that is uniform with other joints of the furniture 4. The joints of the furniture 4 thus run continuously in the horizontal and vertical directions. Accordingly, the Fig. 1 The front of the furniture 4 shown with the furniture door 20 in its closed position presents a pleasing overall visual appearance.

[0031] In order to move the furniture door 20 from its closed position to its Figs. 9 and 10To transfer the furniture door to the opening position shown, a user of system 2 (not shown) triggers an opening command to the stowage mechanism 18 of the stowage device 14 for the automatic opening of the furniture door 20. For example, this opening command can be triggered by tapping the furniture door 20. However, other measures known to those skilled in the art for triggering an opening command for a furniture door are also conceivable. The same applies to the triggering of a closing command to the stowage mechanism 18 for the automatic closing of the furniture door 20.

[0032] After receiving the aforementioned opening command, an adjustment motor (not shown) of the stowage mechanism 18 is controlled by a control (not shown) of the stowage mechanism 18 in such a way that this adjustment motor moves the guide rollers 26 guided in the longitudinal guides 22 in the image plane of the Fig. 2to the left. At the same time, a further adjustment motor (not shown) of the stowage mechanism 18 is controlled in such a way that it is coordinated with the movement of the two guide rollers 26 by means of the control of the stowage mechanism 18 that this adjustment motor moves the two longitudinal guides 22 in the image plane of the Fig. 2 also moves to the left. Due to the above-explained design of the longitudinal guides 22, the two guide rollers 26 are deflected upwards by means of the second sections 32 of the longitudinal guides 22. The guide rollers 26 are thus guided in the longitudinal guides 22 in such a way that the guide rollers 26 are absolutely in the image plane of the Fig. 2 to the left and up. See the Fig. 2 to Fig. 5Due to the rigid coupling of the guide rollers 26, 28 explained above, the guide rollers 28 guided in the longitudinal guides 24 are automatically moved during this movement, wherein the guide rollers 28 each guide the second section 38 of the longitudinal guides 24 in the respective image plane of the Fig. 2 to 5 from bottom to top. This combined movement of the guide rollers 26, 28 ensures collision-free pivoting of the furniture door 20 when transferring the furniture door 20 from its closed position to its open position.

[0033] When the furniture door 20 is pivoted further in the direction of the opening position of the furniture door 20, the longitudinal guides 22 move into a Fig. 6shown left end position. Accordingly, the further pivoting of the furniture door 20 in the direction of the opening position of the furniture door 20 leads to the fact that, on the one hand, the guide rollers 26 guided in the longitudinal guides 22 move along the second sections 32 of the longitudinal guides 22 in the image plane of the Fig. 6 move downwards again and on the other hand the guide rollers 28 guided in the longitudinal guides 24 move along the second sections 38 of the longitudinal guides 24 in the image plane of the Fig. 6 from the second sections 38 of the longitudinal guides 24 via the transition sections 40 into the first sections 36 of the longitudinal guides 24. See the Fig. 6 and 7 in a synopsis. During the movement of the guide rollers 28 along the transition sections 40, the furniture door 20 is positioned in the image plane of the Fig. 6raised again so that the furniture door 20 is also guided past the furniture body 6 and the built-in appliance 12 without collision at this point of transfer of the furniture door 20 from its closed position to its open position.

[0034] In the further course, the guide rollers 26 guided in the longitudinal guides 22 also pass from the second sections 32 of the longitudinal guides 22 via the transition sections 34 into the first sections 30 of the longitudinal guides 22. See also the Fig. 6 and 7 in a summary.

[0035] During the further movement of the furniture door 20 in the direction of its opening position, the guide rollers 26, 28 run in the respective horizontally extending first sections 30, 36 of the corresponding longitudinal guides 22, 24. Accordingly, the height of the furniture door 20 no longer changes during the further movement in the direction of the opening position of the furniture door 20. As soon as the guide rollers 26, 28 each stop at a position in the image plane of the Fig. 9 right end of the respective longitudinal guide 22, 24, the furniture door 20 has reached its open position. The furniture door 20 is then automatically retracted into the storage space 16 of the storage device 14 located under the built-in appliance 12. See the Figs. 9 and 10 .

[0036] In the Fig. 10 There is also a movement track 42 of the Fig. 10 visible guide roller 26. The movement track 42 is shown as a solid line. Furthermore, the Fig. 10visible longitudinal guide 22 in the Fig. 10 shown in both end positions. The image plane of the Fig. 10 further left shown dashed line of the visible second section 32 of the longitudinal guide 22, analogous to the Fig. 6 , the left end position of the longitudinal guide 22. The image plane of the Fig. 10 further right, the dashed line of the visible second section 32' of the longitudinal guide 22 corresponds, analogously to the Fig. 2 , the right end position of the longitudinal guide 22. As can be seen from the Fig. 10 As can be seen, the guide rollers 26 guided in the longitudinal guides 22 describe the movement track 42 when the furniture door 20 is transferred from its closed position to its open position.

[0037] A transfer of the furniture door 20 from its open position to its closed position is triggered and carried out in the manner already explained above with reference to the opening command by means of a closing command to the stowing mechanism 18, analogous to the transfer of the furniture door 20 from its closed position to its open position. Accordingly, the movement of the furniture door 20 results in the reverse order from the Fig. 2 to 10 .

[0038] The furniture door 20 is thus transferred back and forth between its closed position and its open position relative to the furniture body 6 and the built-in appliance 12 by means of the longitudinal guides 22 automatically movable on the built-in appliance 12, wherein the longitudinal guides 22 automatically movable on the built-in appliance 12 and the corresponding guide rollers 26 are automatically moved depending on a closing command and / or opening command of the furniture door 20 applied to the adjustment mechanism. The longitudinal guides 22 automatically movable on the built-in appliance 12 move horizontally in the direction of the built-in niche opening 10 when the furniture door 20 is transferred from its closed position to its open position, and horizontally in the direction opposite to the direction of the built-in niche opening 10 when the furniture door 20 is transferred from its open position to its closed position.When the furniture door 20 is transferred from its closed position to its open position by means of the adjustment mechanism 18, firstly, in a first movement section of the furniture door 20, by moving the longitudinal guides 22, which are automatically movable on the built-in appliance 12, in the direction of the built-in niche opening 10, it is pivoted about a rotation axis (not shown) of the furniture door 20 and simultaneously lifted upwards and secondly, in a second movement section of the furniture door 20 directly following the first movement section, by moving the longitudinal guides 22, which are automatically movable on the built-in appliance 12, in the direction opposite to the direction of the built-in niche opening 10, it is pushed horizontally into the storage space 16.

[0039] Due to the inventive design of the system and the method, it is possible for the furniture door 20 to be transferred back and forth between its closed position and its open position relative to the furniture body 6 and the built-in appliance 12 without collision. The longitudinal guides 22, which are automatically movable on the built-in appliance 12, enable a pivoting movement of the furniture door 20 when transferring the furniture door 20 from its open position to its closed position or vice versa, almost without the translational movement usually associated with a furniture door pivoting about a rotation axis. Accordingly, an undesired collision of the furniture door 20 with the furniture body 6 on the one hand and with the built-in appliance 12 on the other hand is effectively prevented when transferring it from its open position to its closed position or from its closed position to its open position.By means of the invention according to the present exemplary embodiment, a symmetrical appearance of the front of the furniture 4 is also achieved when the furniture door 20 is in the open position. The movement of the furniture door 20 when it is transferred from the closed position to its open position and vice versa is fluid and thus attractive. In the present system 2, the furniture 4 and the built-in appliance 12 can each be designed as standard components, i.e., with conventional standard dimensions. With the furniture door 20 in its closed position, a harmonious overall impression of the front of the furniture 4 results, since the joints formed by the furniture door 20 fit into the remaining joint pattern both horizontally and vertically without cracks or the like.

[0040] The invention is not limited to the illustrated embodiment. For example, the invention can also be advantageously used in other cooking appliances with a cooking chamber or in other built-in appliances. Accordingly, the built-in appliance can also be designed, for example, as a steamer, a microwave oven, a combination appliance with a plurality of different heating functions, or a coffee machine. Furthermore, the invention can be advantageously used in both household appliances and commercial cooking appliances, i.e., cooking appliances for professional use.

[0041] In particular, the invention is not limited to the design and manufacturing features of the illustrated embodiment. For example, it is conceivable that at least two of the longitudinal guides are held on the built-in appliance in a corresponding manner and are mounted on opposite sides of the furniture door in a merely movable manner. Accordingly, the furniture door could be manually moved from its closed position to its open position and vice versa. In contrast to the exemplary embodiment, it is also possible for at least two of the longitudinal guides to be held on the furniture body in a corresponding manner and are mounted on opposite sides of the furniture door in a movable or automatically movable manner not on the built-in appliance. The same applies to the longitudinal guides that are immovably, i.e., fixedly, arranged on the furniture body and / or on the built-in appliance.
