[0012] In an embodiment, the present invention improves a built-in system including a built-in cooking appliance and a fixing device.

[0013] In an embodiment, the present invention provides a built-in system wherein the fixing device is configured as a latching device; the first fixing element, which is configured as a first latching element, and the second fixing element, which is configured as a second latching element and pre-attached to the furniture unit, being configured and arranged to match each other such that, when the built-in cooking appliance is moved in an installation direction to transfer the built-in system to its installed state, the first latching element comes into latching engagement with the second latching element such that the built-in cooking appliance is held to the furniture unit along the installation direction when the built-in system is in the installed state.

[0014] The advantage provided by the invention is, in particular, that a built-in system including a built-in cooking appliance and a fixing device is improved. The inventive design of the built-in system significantly simplifies the installation of the built-in cooking appliance into an installation niche of a furniture unit, such as a kitchen furniture unit. An installer only has to push the built-in cooking appliance into the installation niche, i.e., only move it in the installation direction. In doing so, the two latching elements come into latching engagement, and the built-in cooking appliance is held to the furniture unit both in the installation direction and in a direction opposite to the installation direction. Accordingly, installation can always be carried out without tools.

[0015] The built-in system according to the invention can, in principle, be freely selected within wide suitable limits in terms of type, function, material, arrangement of components, and dimensions. For example, the invention can be advantageously used both with household appliances and with commercial appliances, i.e. built-in cooking appliances for professional use. Furthermore, the inventive built-in cooking appliance may be in the form of, for example, an oven, a steam cooker, a microwave oven, or a combination appliance having a plurality of different types of heating.

[0016] An especially advantageous refinement of the built-in system according to the invention provides that the first latching element has a peg and the second latching element is configured as a catch corresponding to the peg, or that the first latching element is configured as a catch and the second latching element has a peg corresponding to the catch. In this way, the two latching elements, and thus the latching device, are designed to be particularly simple, robust, and functionally reliable in terms of construction and manufacture.

[0017] An advantageous refinement of the aforementioned embodiment of the built-in system provides that the peg and the catch are configured to match each other such that the peg, which is connected to the catch when the built-in system is in the installed state, is disengageable by a removal force acting in a direction opposite to the installation direction. This not only enables a simplified installation of the inventive built-in system, i.e., a simplified transfer of the inventive built-in system to the installed state, but also enables the built-in system to be transferred from the installed state back to the removed state; i.e. a transfer of the inventive built-in system to the removed state.

[0018] A particularly advantageous refinement of the latter two embodiments of the built-in system according to the invention provides that the peg and the catch are configured and arranged to match each other so as to compensate for tolerances, preferably, that the peg and the catch are configured to compensate for tolerances perpendicular to the installation direction, particularly preferably, that the catch is oversized compared to the peg along a vertical axis and to such an extent that the peg is securely held in the catch, despite any tolerances along the vertical axis This ensures proper functioning of the built-in system, even when there are component and assembly tolerances. This applies particularly to the preferred embodiment. The particularly preferred embodiment further provides a way to compensate for such tolerances that is very easy to implement in terms of design and production.

[0019] A further advantageous refinement of the built-in system according to the invention provides that the first latching element is formed as a plastic part, preferably, that the first latching element is releasably attached to the front frame, particularly preferably, that the first latching element is attached to the front frame by means of latching connections. This firstly makes the first latching element cost-effective and flexible to manufacture. Secondly, in the case of front frames made from metal, e.g., stainless steel, an advantageous combination of materials is obtained in this way. The preferred embodiment has the further advantage that the first latching element is not only detachable from the front frame, but that this can be accomplished very easily. The aforementioned advantages apply especially to the particularly preferred embodiment of this refinement, which allows for both easy installation and easy removal of the first latching element.

[0020] An advantageous refinement of the inventive built-in system described herein provides that, in a plan view, the peg is configured as an acute-angled wedge at a free end of the peg, preferably, that in this top view, the acute-angled wedge merges into a constriction of the peg on both sides thereof in a direction toward a root of the peg, this transition being configured as an obtuse-angled wedge, and the catch being configured to correspond to this peg. This allows the built-in system to be transferred to the installed state with relatively little force. The preferred embodiment of this refinement further ensures that, in the installed state, the peg is held by the catch with sufficient retention force, despite the above-described simplification in the transfer to the installed state. Thus, the peg and the catch are here configured to match each other such that, firstly, the built-in system can be easily transferred to the installed state and that, secondly, the built-in cooking appliance is functionally securely held to the furniture unit when in the installed state.

[0021] An advantageous refinement of the inventive built-in system as described herein provides that the catch is configured as a spring having two lateral spring arms, the spring arms latchingly cooperating with the peg when in engagement therewith, preferably, that the two lateral spring arms are disposed on a central base plate of the catch for attachment of the catch to the furniture unit or to the front frame, particularly preferably, that the catch is configured as a single-piece sheet-metal member. In this way, the catch is configured to be a particularly simple in terms of construction and manufacture. The preferred embodiment of this refinement also has the advantage that the catch firstly has a central portion for attachment to the furniture unit and, secondly, a portion separate therefrom for force-transmitting engagement of the catch with the peg. Accordingly, the above-mentioned portions can be tailored to the respective function. The particularly preferred embodiment of this refinement further provides a particularly simple and robust implementation of the catch.

[0022] An advantageous refinement of the latter refinement of the built-in system according to the invention provides that the base plate is formed with markings to assist in the attachment of the catch to the furniture unit, preferably that one catch for holding a peg when the built-in system is in the installed state is provided on each side of the built-in cooking appliance on a side panel of the furniture unit, the markings being arranged so as to assist in installing the built-in cooking appliance centrally between two side panels of the furniture unit, particularly preferably, that the markings are suitably arranged for side panels having wall thicknesses of 16 mm and 19 mm. In this way, the attachment of the catch to the furniture unit is significantly simplified with little additional effort. When attaching the catch, the installer can bring furniture edges or the like into coincidence with the corresponding markings so as to align the catch with the furniture unit. The markings may be formed, for example, as notches or the like on the catch. The preferred embodiment is particularly advantageous because it also enables the built-in cooking appliance to be spatially aligned relative to the furniture unit, namely to laterally center the built-in cooking appliance in the installation niche. The particularly preferred embodiment has the additional advantage that the catch can be used for furniture units having different side panel wall thicknesses, namely for side panel wall thicknesses of 16 mm, 19 mm, and 20 mm. This is firstly because the catch has markings for the side panel wall thicknesses of 16 mm and 19 mm, and secondly because the lateral outer edges of the catch, for example of its base plate, represent further markings for a side panel wall thickness of 20 mm.

[0023] An especially advantageous refinement of the built-in system according to the invention provides that the built-in system is configured such that when the built-in system is in the installed state, the latching device is completely invisible to a user of the built-in cooking appliance, even when the cooking chamber door of the built-in cooking appliance is open, preferably, that the latching element associated with the front frame is attached to the front frame such that this latching element is disposed behind a front panel of the built-in cooking appliance in the viewing direction of the user. This significantly improves the overall appearance of the inventive built-in system, in particular of the built-in cooking appliance. This applies especially to the preferred embodiment of this refinement. This advantage is not to be underestimated, especially in the case of premium built-in cooking appliances, as these are designed to meet the highest demands, including in terms of styling. For example, a front frame embodied as a stainless steel front frame comes into its own much better in this way. The aforementioned front panel may, for example, be designed as a control panel, as usual. The front panel and a remainder of a front of the built-in cooking appliance form a unit terms of design and aesthetic appeal, especially in the case of premium built-in cooking appliances. According to this refinement, this overall appearance is not affected by the latching device.

[0024] Further, another advantageous refinement of the built-in system according to the invention provides that the built-in system is suitably configured for tool-lessly transferring the built-in system to the installed state and for tool-lessly transferring the built-in system to a removed state of the built-in system. This allows for easy and time-saving installation and removal of the built-in cooking appliance.

[0025] In FIGS. 1 through 5, an exemplary embodiment of the inventive built-in system is illustrated in purely schematic form.

[0026] Built-in system 2 includes a built-in cooking appliance 4 in the form of a household oven to be built into an installation niche 6 of a furniture unit 8 in the form of a kitchen furniture unit, and further includes a total of two fixing devices for mechanically fixing built-in cooking appliance 4 to furniture unit 8. Built-in cooking appliance 4 includes a housing 10, a cooking chamber 14 disposed in housing 10 and closable by a cooking chamber door 12 of built-in cooking appliance 4, a front frame 16 of stainless steel formed on the housing or connected to housing 10, and a total of two fixing elements attached to front frame 16 and forming part of the fixing device for fixing the built-in cooking appliance 4 to furniture unit 8, the first fixing element of the fixing device cooperating with a second fixing element of the fixing device in such a way that when built-in system 2 is in an installed state, built-in cooking appliance 4 is disposed in installation niche 4 and fixed to furniture unit 8 by means of the fixing device. FIGS. 1a and 1b each show cooking chamber door 12 open, i.e., in an open position.

[0027] In accordance with the invention, the fixing device is configured as a latching device 18; the first fixing element, which is configured as a first latching element 20, and the second fixing element, which is configured as a second latching element and pre-attached to furniture unit 8, being configured and arranged to match each other such that, when built-in cooking appliance 4 is moved in an installation direction to transfer built-in system 2 to its installed state, first latching element 20 comes into latching engagement with the second latching element such that built-in cooking appliance 4 is held to furniture unit 8 along the installation direction when built-in system 2 is in the installed state. The two latching devices 18 are analogous in configuration, so that the following textual descriptions and graphical representations relating to one of the latching devices 18 apply analogously to the latching device 18 that is not described in the text or shown in the drawing.

[0028] First latching element 20 has a peg 22 and the second latching element is configured as a catch 24 corresponding to peg 22 and pre-attached to furniture unit 8. Peg 22 and catch 24 are configured to match each other such that peg 22, which is connected to catch 24 when built-in system 2 is in the installed state, is disengageable by a removal force acting in a direction opposite to the installation direction. Accordingly, built-in cooking appliance 4 can also be transferred from the installed state to the removed state shown in FIG. 1a. In the present exemplary embodiment, built-in system 2 is suitably configured both for tool-lessly transferring built-in system 2 to the installed state and for tool-lessly transferring built-in system 2 to a removed state of built-in system 2. Peg 22 and catch 24 are here configured and arranged to match each other so as to compensate for tolerances, peg 22 and catch 24 being configured to compensate for tolerances perpendicular to the installation direction, namely, by catch 24 being oversized along a vertical axis, as compared to peg 22, and to such an extent that peg 22 is securely held in catch 24, despite any tolerances along the vertical axis. The installation direction points vertically into the image plane in FIG. 1a and extends from bottom to top in FIG. 5. The vertical axis runs from bottom to top in the respective image planes in FIGS. 1a and 1b and perpendicular to the image plane in FIG. 5. Of course, one may conceive of embodiments of the invention where the first latching element is configured as a catch and the second latching element has a peg corresponding to the catch.

[0029] In the present exemplary embodiment, first latching element 20 is formed as a plastic part, the first latching element 20 being releasably attached to front frame 16 by means of latching connections. For this purpose, first latching element 20 has latching noses, and front frame 16 has correspondingly configured latching openings. However, the aforementioned latching connections are not limited to this configuration. In a plan view shown in FIG. 2, peg 22, which is raised from a base plate of first latching element 20 for attachment of first latching element 20 to front frame 16, is configured as an acute-angled wedge at a free end of peg 22. In this top view, the acute-angled wedge merges into a constriction 26 of peg 22 on both sides thereof in a direction toward a root of peg 22, i.e., in a direction toward the base plate, this transition being configured as an obtuse-angled wedge, and catch 24 being configured to correspond to this peg 22. In this regard, see FIGS. 2, 4 and 5 together.

[0030] Catch 24 is here configured as a spring having two lateral spring arms, the spring arms latchingly cooperating with peg 22 when in engagement therewith. In this regard, see FIG. 5. The two lateral spring arms are disposed on a central base plate 28 of catch 24 for attachment of the catch to furniture unit 8. In the present exemplary embodiment, catch 24 is configured as a single-piece sheet-metal member. Base plate 28 is formed with markings 30, 32 to assist in the attachment of catch 24 to furniture unit 8. One catch 24 for holding a peg 22 when built-in system 2 is in the installed state is provided on each side of built-in cooking appliance 4 on a side panel of furniture unit 8, the markings 30, 32 being arranged so as to assist in installing built-in cooking appliance 4 centrally between two side panels of furniture unit 8. Markings 30 correspond to a side panel wall thickness of furniture unit 8 of 16 mm, and markings 32 correspond to a side panel wall thickness of furniture unit 8 of 19 mm. The lateral outer edges of base plate 28 are spaced so far apart that they correspond to a side panel wall thickness of furniture unit 8 of 20 mm. In this regard, see FIG. 3.

[0031] In the present exemplary embodiment, built-in system 2 is further configured such that latching device 18 is completely invisible to a user of built-in cooking appliance 4 when built-in system 2 is in the installed state, even when cooking chamber door 12 of built-in cooking appliance 4 is open. For this purpose, the first latching element 20 associated with front frame 16 is attached to front frame 16 such that this first latching element 20 is disposed behind a front panel 34 of built-in cooking appliance 4 in the viewing direction of the user. Front panel 34 is here configured as a control panel of built-in cooking appliance 4.

[0032] In the following, the functioning of the inventive built-in system according to the present exemplary embodiment will be described with reference to FIGS. 1a through 5.

[0033] Initially, built-in system 2 is in the removed state shown in FIG. 1a. The two catches 24 are attached to a respective one of the two side panels of furniture unit 8 by means of screws and through-holes provided in base plate 28. For this purpose, the two lateral outer edges of the respective base plate 28 serve as markings for alignment of the respective catch 24 with the corresponding side panel of furniture unit 8.

[0034] In order to transfer built-in system 2 from its removed state to its installed state shown in FIG. 1b, the installer grasps built-in cooking appliance 4 and pushes it in the installation direction into installation niche 6 of furniture unit 8. As soon as the two pegs 22 of the first latching elements 20 mounted on front frame 16 engage with the corresponding catches 24, pegs 22 latch with catches 24 so that built-in cooking appliance 4 is held to furniture unit 8 in the installation direction and in a direction opposite to in the installation direction. As this occurs, built-in cooking appliance 4 is also aligned relative to furniture unit 8, namely in the horizontal axis in the image plane of FIG. 1b. The engagement of the respective peg 22 with the corresponding catch 24 is significantly simplified by the free end of peg 22 formed as an acute-angled wedge and the spring arms of catch 24, which are open in the manner of legs. Once peg 22 has been moved far enough in the installation direction, the two spring arms of catch 24 engage behind peg 22 in such a way that peg 22 and catch 24 can only be disengaged by a force greater than that required for transfer to the installed state. Built-in cooking appliance 4 is in its installed state and is detachably fixed along the installation direction by means of pegs 22 and catches 24. The overall appearance of built-in system 2, in particular of built-in cooking appliance 4, is not affected by latching device 18, namely by first latching elements 20 with pegs 22, which are attached to front frame 16, and catches 24 attached to the side panels of furniture unit 8. Instead, the desired aesthetics of the front of built-in cooking appliance 4, including front frame 16 and front panel 34, can fully unfold.

[0035] If it should become necessary to remove built-in cooking appliance 4 from installation niche 6, i.e., to transfer built-in cooking appliance 4 from its installed state to its removed state, this can be done without excessive force and without tools. In this regard, see also the explanations above, but in reverse order.

[0036] The inventive design of built-in system 2 significantly simplifies the installation of built-in cooking appliance 4 into installation niche 6 of furniture unit 8. The installer only has to push built-in cooking appliance 4 into installation niche 6, i.e., only move it in the installation direction. In doing so, the aforementioned latching elements come into latching engagement, and built-in cooking appliance 4 is held to furniture unit 8 both in the installation direction and in a direction opposite to the installation direction. The installation can be carried out without tools.

[0037] While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive. It will be understood that changes and modifications may be made by those of ordinary skill within the scope of the following claims. In particular, the present invention covers further embodiments with any combination of features from different embodiments described above and below. Additionally, statements made herein characterizing the invention refer to an embodiment of the invention and not necessarily all embodiments.

[0038] The terms used in the claims should be construed to have the broadest reasonable interpretation consistent with the foregoing description. For example, the use of the article “a” or “the” in introducing an element should not be interpreted as being exclusive of a plurality of elements. Likewise, the recitation of “or” should be interpreted as being inclusive, such that the recitation of “A or B” is not exclusive of “A and B,” unless it is clear from the context or the foregoing description that only one of A and B is intended. Further, the recitation of “at least one of A, B and C” should be interpreted as one or more of a group of elements consisting of A, B and C, and should not be interpreted as requiring at least one of each of the listed elements A, B and C, regardless of whether A, B and C are related as categories or otherwise. Moreover, the recitation of “A, B and / or C” or “at least one of A, B or C” should be interpreted as including any singular entity from the listed elements, e.g., A, any subset from the listed elements, e.g., A and B, or the entire list of elements A, B and C.
