Description

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

[0002] Such systems and methods for their operation are already known in the art in a multitude of embodiments. The known systems include, for example, a piece of furniture with a built-in niche formed in a furniture carcass and having a niche opening, a built-in appliance for food preparation arranged in the niche, and a storage device with a storage space and a storage mechanism arranged under the built-in appliance in the niche, wherein the built-in appliance arranged in the niche is inaccessible by means of a furniture door of the furniture when the door is closed and accessible when the door is open.and wherein the storage space is designed to accommodate the furniture door in its open position, and the storage mechanism is designed, firstly, to transfer the furniture door from its closed position to its open position and from its open position to its closed position, and secondly, has longitudinal guides arranged on both sides of the furniture door on the furniture body and / or on the built-in appliance, and rotatably arranged guide rollers on the furniture door corresponding to the longitudinal guides.

[0003] A generic system is known from the publication DE 10 2019 102 411 A1, in which the door is inserted into a storage space next to the built-in appliance.

[0004] German publication DE 12 74 306 A describes a built-in appliance with a door that can be inserted into the base of the appliance. The door is movable along a guide rail with at least one guide roller. A slot is formed axially to the guide rail, in which another guide roller is movable.

[0005] The publication DE 10 2006 002 409 A1 shows a built-in appliance with a door that can be inserted into the base of the appliance. The door is movable by means of a guide element with at least one guide roller along a single fixed guide on each side of the door.

[0006] Publication US 2007 / 0159037A1 discloses a furniture carcass with a furniture door that can be inserted laterally into the carcass, wherein the furniture door is movable along two fixed longitudinal guides.

[0007] The publication DE 199 06 913 A1 also reveals two immovable longitudinal guides for a door in a built-in appliance.

[0008] The printed document WO 02 / 101185 A1 shows a single fixed longitudinal guide with a branch at one of the end sections of the longitudinal guide.

[0009] The invention is based on the objective 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.

[0010] According to the invention, this problem is solved by a system having the features of claim 1. Furthermore, this problem is solved by a method having the features of claim 10.

[0011] The built-in appliance for food preparation can be, for example, an oven, a microwave oven, a steam cooker, a combination oven with multiple different heating modes, or a coffee machine. The aforementioned list is purely exemplary and not exhaustive. Furthermore, the built-in appliance can be 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 described in the following dependent claims.

[0012] The advantage achievable with the invention lies particularly 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 moved back and forth between its closed and open positions relative to the furniture body and the built-in appliance without collision. The longitudinal guides, which are movably or automatically movable on the furniture body and / or the built-in appliance, enable a pivoting movement of the furniture door when moving from its open position to its closed position or vice versa, almost without the translational movement usually associated with a furniture door that pivots about an axis of rotation.Accordingly, an unwanted collision of the furniture door with the furniture body and the built-in appliance during its movement from the open to the closed position, or vice versa, is effectively prevented.

[0013] In principle, the system can be freely selected within wide suitable limits in terms of type, function, material and dimensions.

[0014] An advantageous further development of the system according to the invention provides that the adjustment mechanism is designed such that the longitudinal guides and / or the corresponding guide rollers, which are automatically movable and held on the furniture body and / or the built-in device, are automatically movable depending on a closing and / or opening command of 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 moving it from its closed position to its open position and vice versa is no longer necessary. A user of the system thus has their hands free for other tasks. Furthermore, the adjustment mechanism can be controlled by a multitude of closing and / or opening commands from different devices.These devices could, for example, be the built-in appliance installed in the recess. The closing and / or opening commands could be triggered by the built-in appliance itself, depending on a predefined operating state and / or a predefined automatic program running within the appliance. Alternatively, the closing and / or opening commands could be triggered by a mobile device, such as a smartphone or similar device.

[0015] A further advantageous embodiment of the system according to the invention provides 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 each side of the furniture door such that the two longitudinal guides arranged on one side are arranged one above the other and spaced apart from each other, preferably that the two guide rollers arranged on one side are arranged at a constant distance on the furniture door regardless of the position of the furniture door relative to each other, particularly preferably that these guide rollers are each arranged at a constant distance from an inner side of the furniture door.This allows the system according to the invention, in particular the storage mechanism of the system according to the invention, to be implemented in a structurally and technically robust and functionally reliable manner. This applies particularly to the preferred and especially to the particularly preferred embodiment of this further development. For example, the aforementioned spacing of the guide rollers enables a sufficiently long lever arm to absorb the weight force of the furniture door acting in its open position, i.e., in its horizontal position, by means of the storage mechanism without additional aids such as Teflon glides or the like.

[0016] An advantageous further development of the aforementioned further development of the system according to the invention provides that the longitudinal guides arranged at the top of both sides are designed as the longitudinal guides that are movably or automatically movable and are held on the furniture body and / or the built-in appliance; preferably, only the two aforementioned longitudinal guides are designed as the longitudinal guides that are movably or automatically movable and are held on the furniture body and / or the built-in appliance. In this way, the design and manufacturing of the system according to the invention are further simplified. This applies in particular to the preferred embodiment of this further development.

[0017] An advantageous further development of the two latter 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 furthest from the installation niche opening and a second section extending transversely upwards, preferably vertically upwards, towards the first section, wherein the first and the second sections are connected to each other by means of a transition section of the respective longitudinal guide in a guide roller-guiding manner. This ensures that 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 two latter embodiments of the system according to the invention.

[0018] An advantageous embodiment of the system according to the invention, as defined in one of claims 3 to 5, provides that the longitudinal guides arranged at the bottom of both sides have a horizontally extending first section farther from the installation niche opening and a second section near the installation niche opening, extending transversely downwards to the first section, preferably in a downward curve, wherein the first and second sections are connected to each other by means of a transition section of the respective longitudinal guide in a guide roller-guiding manner, preferably in that the transition section extends continuously upwards from the first section 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 are also implemented in a robust and therefore functionally reliable manner according to one of the last three embodiments of the system according to the invention.

[0019] A particularly advantageous embodiment of the system according to the invention provides that the guide rollers are arranged on the furniture door in such a way that the overall width of the furniture door remains constant regardless of whether the guide rollers are present on the furniture door. This makes it possible to advantageously use the system according to the invention even with furniture and built-in appliances of standard dimensions. It is therefore not necessary, for example, to design and manufacture the furniture carcass and / or the built-in appliance installed in the recess of the furniture carcass with dimensions that deviate from standardized ones. Accordingly, the application of the system according to the invention is also simplified, since, according to this embodiment, the system according to the invention is designed to fit the standard dimensions commonly used for furniture with recesses and built-in appliances for such recesses.Thus, according to the present further development, the system according to the invention is also suitable for subsequent conversion, i.e. as a retrofit kit.

[0020] Analogous to the aforementioned further development of the system according to the invention, another advantageous further development of the system according to the invention provides that the storage mechanism and the furniture door are designed to be coordinated in such a way that the depth of the installation niche is constant, regardless of whether the storage space is located under the built-in appliance or whether the furniture door is located in the open position within that storage space. In this way, the required depth of the installation niche is minimized; in particular, the depth of the installation niche does not need to extend beyond the dimensions of the furniture door in the open position, or only by a few centimeters. It is even possible that a depth of the installation niche deviating from 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.

[0021] A further advantageous embodiment of the system according to the invention provides that the storage mechanism is designed such that the longitudinal guides, which are movably or automatically movable on the furniture body and / or the built-in appliance, are movable horizontally towards the opening of the built-in niche when the furniture door is moved from its closed position to its open position, and horizontally in the opposite direction to the opening of the built-in niche when the furniture door is moved from its open position to its closed position. This results in a simple movement sequence for the longitudinal guides, which are movably or automatically movable on the furniture body and / or the built-in appliance, so that these longitudinal guides are implemented in a particularly simple manner from a design and manufacturing perspective.Due to the simple movement sequence, for example, unwanted 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 further development.

[0022] The direction of the recessed opening is defined as running from the back of the furniture to the front. According to one aspect, the direction of the recessed opening is orthogonal to the plane of the furniture front or to the plane of the furniture door in the closed position.

[0023] Accordingly, an advantageous further development of the method according to the invention provides that the longitudinal guides, which are movably or automatically movable on the furniture body and / or the built-in device, are moved horizontally in the direction of the installation niche opening when the furniture door is moved from its closed position to its open position, and horizontally in the opposite direction to the direction of the installation niche opening when the furniture door is moved from its open position to its closed position.

[0024] A further advantageous embodiment of the method according to the invention provides that, when the furniture door is moved from its closed position to its open position by means of the adjustment mechanism, firstly, in a first movement phase of the furniture door, by moving the longitudinal guides, which are movably or automatically movable and held on the furniture body and / or the built-in appliance, in the direction of the installation niche opening, is pivoted about an axis of rotation of the furniture door and is simultaneously lifted upwards, and secondly, in a second movement phase of the furniture door, which immediately follows the first movement phase, by moving the longitudinal guides, which are movably or automatically movable and held on the furniture body and / or the built-in appliance, in the opposite direction to the direction of the installation niche opening, is inserted horizontally into the storage space.In this way, the overall movement of the furniture door of the system according to the invention, when transitioning to its open position, is divided into functionally separate movement segments. Accordingly, each of the two movement segments can be designed in a predetermined manner for its specific function, thus significantly simplifying the construction of the adjustment mechanism. The same applies to the transition of the furniture door from its open position to its closed position. However, in this case, the aforementioned movement segments are traversed in reverse order.

[0025] An embodiment of the invention is shown purely schematically in the drawings and is described in more detail below. It shows Fig. 1 An embodiment of the system according to the invention for carrying out the method according to the invention in a frontal view, with the furniture door in its closed position, Fig. 2 the embodiment in a partial, cutaway side view, with the furniture door in its closed position, Fig. 3 the embodiment in a partial, cutaway side view, with the furniture door in a first intermediate position, Fig. 4 the embodiment in a partial, cutaway side view, with the furniture door in a second intermediate layer, Fig. 5 the embodiment in a partial, cutaway side view, with the furniture door in a third intermediate layer, Fig. 6 the embodiment in a partial, cutaway side view, with the furniture door in a fourth intermediate layer, Fig. 7 the embodiment in a partial, cutaway side view, with the furniture door in a fifth intermediate layer, Fig. 8 the embodiment in a partial, cutaway side view, with the furniture door in a sixth intermediate layer, Fig. 9 the embodiment in a partial, cutaway side view, with the furniture door in its open position and Fig. 10 the embodiment in a partial, cut-away side view, with the furniture door in its open position, with a movement trace of the guide roller guided in the upper longitudinal guide.

[0026] In the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 to Fig. Figure 10 is an embodiment of the system according to the invention for carrying out the method according to the invention, shown purely by way of example.

[0027] System 2 comprises a piece of furniture 4 designed as kitchen furniture with a built-in niche 8 formed in a furniture carcass 6 of the furniture 4, the niche opening being 10; a built-in appliance 12 designed as an oven for preparing food, arranged in the niche 8; and a storage device 14 with a storage space 16 and a storage mechanism 18 arranged under the built-in appliance 12 in the niche 8, wherein the built-in appliance 12 arranged in the niche 8 is concealed by means of a furniture door 20 of the furniture 4 in a recess 10 that covers the niche 8. Fig. 1 and Fig. 2. The closed position of the furniture door 20 shown is inaccessible and in a position that is in the Fig. 9 and Fig. 10 shown, the open position of the furniture door 20 is accessible, and the storage space 16 is designed to accommodate the furniture door 20 in its open position.

[0028] The storage mechanism 18 is designed, firstly, to transfer the furniture door 20 from its closed position to its open position and from its open position to its closed position. Secondly, the storage mechanism 18 has longitudinal guides 22, 24 arranged on both sides of the furniture door 20 on the built-in device 12, and rotatably arranged guide rollers 26, 28 on the furniture door 20 corresponding to the longitudinal guides 22, 24. In the Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 to Fig. In Figure 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 in the Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 to Fig. 10 is symbolized by means of dashed lines. The corresponding guide rollers 26, 28 and their mounting on the furniture door 20 are shown in the Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 to Fig. Figure 10 is also shown in a highly simplified form for the sake of clarity. The non-visible longitudinal guides and guide rollers are designed and arranged on the other side of the built-in appliance 12 and the furniture door 20 analogously to the visible longitudinal guides 22, 24 and guide rollers 26, 28.

[0029] According to the invention, two of the longitudinal guides 22, 24, namely the longitudinal guides 22, are corresponding to each other and automatically movable on opposite sides of the furniture door 20 on the installation device 12 such that the furniture door 20 can be moved back and forth between its closed and open positions relative to the furniture body 6 and the installation device 12 without collision. The adjustment mechanism 18 is designed such that the longitudinal guides 22, which are automatically movable on the installation device 12, and the corresponding guide rollers 26 are automatically movable depending on a closing and / or opening command of the furniture door 20 applied to the adjustment mechanism 18.

[0030] Thus, four longitudinal guides 22, 24 are mounted on the built-in appliance 12, and four guide rollers 26, 28 are mounted on the furniture door 20, with each of the four guide rollers 26, 28 corresponding to one of the longitudinal guides 22, 24, and with two of the four longitudinal guides 22, 24 being arranged on either side of the furniture door 20 such that the two longitudinal guides 22, 24 located on one side are arranged one above the other and spaced apart from each other, namely such that the two guide rollers 26, 28 located on one side are arranged at a constant distance from each other on the furniture door 20, regardless of the position of the furniture door 20 relative to each other. Furthermore, these guide rollers 26, 28 are each arranged 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 such that the overall width of the furniture door 20 remains constant regardless of whether the guide rollers 26, 28 are present on the furniture door 20. Accordingly, the overall width of the furniture door 20 does not change with 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 is perpendicular to the plane of the image. Fig. 2.

[0031] In the present embodiment, only the longitudinal guides 22 arranged at the top of both sides are designed as the longitudinal guides 22 that are automatically movable on the installation device 12. These longitudinal guides 22 arranged at the top of both sides have a first section 30 extending horizontally away from the installation niche opening and a second section 32 extending transversely upwards, i.e., vertically upwards, near the installation niche opening, wherein the first and the second sections 30, 32 are connected to each other by means of a transition section 34 of the respective longitudinal guide 22 in a guide roller-guiding manner.

[0032] In contrast, the longitudinal guides 24 arranged at the bottom of both sides are fixed to the built-in device 12. These longitudinal guides 24, arranged at the bottom of both sides, have a first section 36 extending horizontally away from the installation niche opening and a second section 38 extending transversely downwards to the first section 36 in a downward curve closer to the installation niche opening. The first and second sections 36, 38 are connected to each other by means of a transition section 40 of the respective longitudinal guide 24, guided by guide rollers. In the present embodiment, the transition section 40 is designed such that, starting from the first section 36, it first extends continuously upwards to a vertex and then from the vertex downwards into the second section 38.

[0033] The storage mechanism 18 and the furniture door 20 are designed to be coordinated in such a way that the depth of the installation niche 8 remains constant regardless of whether the storage space 16 located below the built-in appliance 12 and the furniture door 20 in its open position within this storage space 16 are present. Accordingly, the presence of the storage device 14 necessitates a depth of the installation niche 8 that is no greater, or only a few centimeters greater, than the depth of the furniture door in its open position. The depth of the installation niche 8 lies in the plane of the image. Fig. 2 horizontal.

[0034] The storage mechanism 18 is further designed such that the longitudinal guides 22, which are automatically movable on the built-in device 12, are movable horizontally towards the installation niche opening 10 when the furniture door 20 is moved from its closed position to its open position, and horizontally in the opposite direction to the installation 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.

[0035] The following describes the functioning of the system and the method according to the present embodiment. Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 to Fig. 10 explained in more detail.

[0036] First, the furniture door 20 of system 2 is located in its in the Fig. 1 and Fig. 2 shown in the closed position. In this closed position, the cabinet door 20 covers, firstly, the recess opening 10 and thus the recess 8. Secondly, in its closed position, the cabinet door 20 prevents access to the built-in appliance 12 located in the recess 8. In the closed position of the cabinet door 20, the cabinet door 20 forms a uniform joint pattern with the remaining part of the cabinet 4 in both the horizontal and vertical directions. The joints of the cabinet 4 thus run continuously in both the horizontal and vertical directions. Accordingly, the joint pattern shown in 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.

[0037] To remove the furniture door 20 from its closed position into its Fig. 9 and Fig. To convert the opening position shown in Figure 10, a user of system 2 (not shown) triggers an opening command to the storage mechanism 18 of the storage 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 triggering a closing command to the storage mechanism 18 for the automatic closing of the furniture door 20.

[0038] After receiving the aforementioned opening command, an adjustment motor (not shown) of the stowage mechanism 18 is controlled by means of a control unit (not shown) of the stowage mechanism 18 such that this adjustment motor moves the guide rollers 26, which are guided in the longitudinal guides 22, in the plane of the image. Fig. 2 to the left. Simultaneously, another adjustment motor (not shown) of the stowing mechanism 18 is controlled by the control unit of the stowing mechanism 18 in such a way as to synchronize the movement of the two guide rollers 26, such that this adjustment motor moves the two longitudinal guides 22 in the plane of the image. Fig. 2 also moved to the left. Due to the design of the longitudinal guides 22 explained above, 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 aligned in the image plane of the Fig. Move 2 to the left and upwards. See the Fig. 2 to Fig. 5. Due 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 along with this movement, with the guide rollers 28 each following the second section 38 of the longitudinal guides 24 in the respective plane of the Fig. 2, Fig. 3, Fig. 4 to Fig. 5 from bottom to top. This combined movement of the guide rollers 26, 28 ensures a collision-free pivoting of the furniture door 20 when transferring the furniture door 20 from its closed position to its open position.

[0039] As the furniture door 20 pivots further towards the opening position of the furniture door 20, the longitudinal guides 22 enter a position in the Fig. The left end position is shown in Figure 6. Accordingly, further pivoting of the furniture door 20 towards the open position of the furniture door 20 results in the guide rollers 26, guided in the longitudinal guides 22, moving along the second sections 32 of the longitudinal guides 22 in the plane of the image. Fig. 6 move downwards again and secondly 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. Move 6 of 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 Fig. 7 in a summary. During the movement of the guide rollers 28 along the transition sections 40, the furniture door 20 is moved in the plane of the image due to the above-explained design of these transition sections 40. Fig. 6 is raised again so that the furniture door 20 is guided past the furniture body 6 and the built-in appliance 12 without collision at this point of the transition of the furniture door 20 from its closed position to its open position.

[0040] In the next step, the guide rollers 26, which are guided in the longitudinal guides 22, also move 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 Fig. 7 in a summary.

[0041] As the furniture door 20 moves further towards its open 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 its further movement towards the open position. As soon as the guide rollers 26, 28 are each on a section 30, 36 in the plane of the image, the guide rollers 26, 28 run in the horizontally extending first sections 30, 36 of the corresponding longitudinal guides 22, 24. Fig. Once the right end of the respective longitudinal guide 22, 24 has been reached, the furniture door 20 has reached its open position. The furniture door 20 is then automatically retracted into the storage compartment 16 of the storage device 14 located below the built-in appliance 12. See the Fig. 9 and Fig. 10.

[0042] In the Fig. 10 is additionally a movement track 42 of the in the Fig. The visible guide roller 26 is shown. The movement track 42 is represented as a solid line. Furthermore, the one in the Fig. 10 visible longitudinal guide 22 in the Fig. 10 shown in both end positions. The image plane of the Fig. The dashed line shown 10 further to the left of the visible second section 32 of the longitudinal guide 22 corresponds, analogously to the Fig. 6, the left end position of the longitudinal guide 22. The one in the image plane of the Fig. The dashed line shown 10 further to the right 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. As can be seen from Figure 10, the guide rollers 26 guided in the longitudinal guides 22 describe the movement track 42 when the furniture door 20 is moved from its closed position to its open position.

[0043] The movement 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 storage mechanism 18, analogous to the movement 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 sequence from the Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 to Fig. 10.

[0044] The furniture door 20 is thus moved back and forth between its closed and open positions relative to the furniture carcass 6 and the built-in device 12 without collision by means of the longitudinal guides 22, which are automatically movable on the built-in device 12. The longitudinal guides 22 and the corresponding guide rollers 26 are moved automatically depending on a closing and / or opening command of the furniture door 20 applied to the adjustment mechanism. When the furniture door 20 moves from its closed position to its open position, the longitudinal guides 22 move horizontally in the direction of the installation niche opening 10. When the furniture door 20 moves from its open position to its closed position, the longitudinal guides 22 move horizontally in the opposite direction to the installation niche opening 10.When the furniture door 20 is moved from its closed position to its open position by means of the adjustment mechanism 18, firstly, in a first movement phase of the furniture door 20, by means of movement of the automatically movable longitudinal guides 22 held on the built-in device 12 in the direction of the installation niche opening 10, is pivoted about an axis of rotation of the furniture door 20 (not shown) and simultaneously raised upwards, and secondly, in a second movement phase of the furniture door 20 immediately following the first movement phase, by means of movement of the automatically movable longitudinal guides 22 held on the built-in device 12 in the opposite direction to the direction of the installation niche opening 10, it is pushed horizontally into the storage space 16.

[0045] Due to the inventive design of the system and the method, it is possible for the furniture door 20 to be moved back and forth between its closed and open positions relative to the furniture body 6 and the built-in device 12 without collision. The longitudinal guides 22, which are automatically movably held on the built-in device 12, allow the furniture door 20 to pivot when moving from its open to its closed position or vice versa, almost without the translational movement usually associated with a furniture door pivoting about an axis of rotation. Accordingly, an unwanted collision of the furniture door 20 with the furniture body 6 and with the built-in device 12 is effectively prevented when moving from its open to its closed position or vice versa.Furthermore, according to the present embodiment of the invention, the front of the furniture 4 also has a symmetrical appearance when the furniture door 20 is open. The movement of the furniture door 20 when transitioning from the closed to the open position and vice versa is smooth and therefore aesthetically pleasing. In the present system 2, the furniture 4 and the built-in appliance 12 can each be designed as standard components, i.e., with standard dimensions. With the furniture door 20 in its closed position, the front of the furniture 4 presents a harmonious overall impression, since the joints formed by the furniture door 20 blend seamlessly into the surrounding joint pattern, both horizontally and vertically, without any gaps or similar irregularities.

[0046] The invention is not limited to the described 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 steam cooker, a microwave oven, a combination appliance with several 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.

[0047] The invention is not limited to the design and manufacturing features of the described embodiment. For example, it is conceivable that at least two of the longitudinal guides are mutually corresponding and movably mounted on opposite sides of the cabinet door to the built-in appliance. Accordingly, the cabinet door could be manually moved from its closed position to its open position and vice versa. In contrast to the embodiment described, it is also possible that at least two of the longitudinal guides are mutually corresponding and movably mounted on opposite sides of the cabinet door not to the built-in appliance, but to the cabinet body, either movably or automatically. The same applies to the longitudinal guides that are fixed, i.e., immovably mounted, on the cabinet body and / or the built-in appliance.
