- the lower edges of the hooks 66 are spaced from said top surface by forming a gap 74 in between after fixation of the entire extraction fan 36 to the bottom wall 60. That way, in normal condition, e. g. directly after the assembly of the combination appliance 10, and without any shock impact thereon, the hooks 66 do not perform any supporting function.

- the general working concept of the fastening system herein disclosed is as follows. Due to the fact that the combination appliance 10 comprises heavy components like the extraction fan 36, which are attached to other components like the cooking hob wall 60, there is a risk of damages specifically during transportation or installation of the combination appliance 10, especially in case of an unintended drop of the appliance 10 causing shocks and related displacement forces acting on the individual components. Rigid connections of these components directly transmit emerging forces caused by these shocks to the parts or components that are connected to them. In the specific case of the cooktop 22 comprising a glass ceramic plate, more specifically having a cutout forming or comprising the suction opening 24, there is a high risk for damages on the glass material because cut surfaces and edges of glass material provide weak points of the entire element.
- the principal purpose of the specific fastening system provides a combination of one or more flat flaps 68 and one or more very strong hooks 66 with orientation orthogonally to the mounting plane, which are arranged on a connection part, specifically on the motor plate 64 of the extraction fan 36.
- Said hooks 66 and flaps 68 may be positioned in a central area or in a side area of the connection part, or in any position therebetween.
- the flat flaps 68 are deformed elastically within the limits of the material properties of the used material, which is preferably a metal.
- the result may be only an elastic deformation of the flaps 68.
- a more enhanced shock intensity inducing a higher relative movement leads to a plastic deformation of the flaps 68, which plastic deformation process includes an increased shock absorption capacity.
- the vertically oriented hooks 66 allow said relative movement of the component and the related elastic and plastic deformation of the flat flaps 68 within the predefined distance, corresponding to the provided gap 74, only.
- the vertical hooks 66 are sufficiently rigid for keeping the relative movement within said predefined distance. To this end, it is provided that no such shocks and related forces shall be taken into account, which would end up with any plastic deformation of the hooks 66.
- the fastening system is preferably designed in such a way, that drop tests, as required by standards in the household business, will at most lead to plastic deformation of the flaps 68, but will not lead to any plastic deformation of the hooks 66.
- the shocks during transport and installation may be compensated by elastic and plastic deformation of the flat flaps 68, while the vertically oriented hooks 66 ensure a proper retaining positioning of all components.
- the included gap 74 is dependent on the maximum elastic deformation level of the material as well as the distance of the hooks 66 to the flaps 68.
- the fixation system may include a plurality of pairs of cooperating flaps 68 and hooks 66 in a way that the motor plate 64 is entirely attached by these means to the bottom wall 60 of the cooking hob housing 58.
- the motor plate 64 may be fastened to the bottom wall 60 of the cooking hob housing 58 on only one side, while the other side of the motor plate 64 may comprise fastening means, e. g. screws and related holes, for a rigid connection to the bottom wall 60 after said displacement of the motor plate 64 alongside the bottom surface of the bottom wall 60, so that the inventive concept will operate only one-sided, which may reduce the protective effect of the fastening system but may nevertheless be a sufficient solution.
- the fastening system can be downsized and the number of involved parts can be reduced.
- No flexible parts like silicone, rubber or springs are necessary as it is provided in solutions known from the prior art.
- such flexible or soft parts might be used in addition.
- the packaging of the entire combination appliance 10 for its safe transportation may be designed less complex and in a more cost-efficient way.
- combination appliance 10 with specific dimensions is presented by FIGs. 1 to 6
- the herein described setups of combination appliance 10 may be applicable to all known sizes of cooking hobs 12 and respective combination appliances 10 with a width of at least 580 mm. Two, three or four cooking zones may be provided, specifically depending on the size of the cooking hob 12.

Description
- The present invention relates to a household appliance comprising a fastening system for an attachment of a component or an assembly to a casing wall or to a frame or support part according to the preamble of
claim 1. - In order to support persons in performing domestic work, household appliances of different kinds are known. In particular, cooking processes are performed using cooking appliances. For example, cooking hobs comprise cooking zones for placement of cookware receiving the food to be cooked. The cooking zones are generally arranged on a cooktop, in particular a glass ceramic cooktop, which forms an upper wall of the cooking hob. Moreover, there are cooking hobs known, in which a cooking fumes extraction functionality is integrated. More specifically, such kind of a combination appliance comprises a cooking hob and an integrated downdraft extraction device with an extraction opening in the cooktop of the cooking hob. With such a combination of a cooking hob and an extraction device, a compact solution is provided. On the other hand, each type of household appliance, but particularly such a combination appliance, requires a plurality of mechanical fastening solutions, which are exposed to different mechanical stress situations during the lifetime of the household appliance, especially during its transportation and/or installation, where vibrations or shocks usually occur.
- It is an object of the present invention to provide a household appliance comprising a fastening system for an attachment of a component or an assembly to a casing wall or to a frame or support part, having a, preferably cost-efficient, solution for such a fastening system, which is designed to ensure prevention of damages to the household appliance under the impact of a mechanical stress situation usually occurring during the lifetime of the appliance.
- The object is achieved for a household appliance comprising a fastening system for an attachment of a component or an assembly to a casing wall or to a frame or support part by the characterizing features of
claim 1. - A household appliance comprises a fastening system for an attachment of a component or an assembly at a casing wall or at a frame or support part. The fastening system according to the present invention includes at least a first fastening means and a second fastening means. The first fastening means is configured to be plastically deformed under the influence of a first force exceeding a first force threshold and the second fastening means is configured to be plastically deformed under the influence of a second force exceeding a second force threshold. The first and second forces are directed orthogonally to the mounting plane. The first force threshold is lower than the second force threshold.
- The household appliance is particularly a cooking appliance, more particularly a cooking hob or a combination appliance comprising a cooking hob. Further, said mounting plane is particularly the area of attachment of the component or assembly at the casing wall or frame or support part, e. g. the area of the component or assembly abutting against or touching the casing wall or frame or support part.
- With such dimensioning of first and second fastening means, it may be provided that a plastic deformation of the first fastening means occurs at a force level, specifically arising from a particular shock impulse, which force level will at most cause an elastic deformation or displacement of the second fastening means.
- The second force threshold is preferably higher than a predetermined force value, the fastening system is required to withstand throughout the entire lifetime of the household appliance. This entire lifetime particularly includes the transportation and/or installation of the household appliance, during which it usually receives the major mechanical impact, e. g. stress situations like vibrations and/or shocks. On the other hand, the first force threshold may be lower than said predetermined value, which may cause the first fastening means to undergo a plastic deformation in case of occurrence of a force, e. g. sourcing from a shock impulse, with a force level that may appear, during the lifetime of the appliance, specifically during transportation or installation.
- In some implementations, the first fastening means is configured to absorb a shock by an elastic deformation, if this shock includes a force within a first force value range, and by a plastic deformation, if this shock includes a force within a second force value range. The second force value range is specifically above the first force value range, i. e. a lower limit value of the second force value range is higher than the upper limit value of the first force value range. More specifically, the lower limit value of the second force value range abuts the upper limit value of the first force value range.
- Moreover, the fastening system may include a shock absorption capacity within the second force value range, which is increased in comparison with the first force value range. Said increased shock absorption capacity is preferably induced by absorption of mechanical deformation energy associated with plastic deformation.
- According to an embodiment, the first fastening means and the second fastening means are located in close proximity to each other. With such positioning, the first and second fastening means may closer cooperate with each other, specifically in dependence of the force that is applied. However, a more distant positioning may work as well, what may also depend on the exact location of the respective fastening means, e. g. a positioning close to a centre of gravity of the entire system.
- One specific solution for the household appliance according to the present invention provides that the fastening system comprises a plurality of first fastening means and a plurality of second fastening means. Preferably, one of each of the plurality of first fastening means and one of each of the plurality of second fastening means form a pair of first and second fastening means, so as to have provided a plurality of pairs of first and second fastening means. In such construction, each pair includes one first and one second fastening means, which are located close to each other.
- According to a particularly specific embodiment, the first fastening means comprises at least one fastening flap, preferably a plurality of fastening flaps. Additionally, or alternatively, the second fastening means comprises at least one fastening hook, preferably a plurality of fastening hooks.
- In some implementations, a main direction of extent of the fastening flap is oriented parallel to the mounting plane, the fastening flap preferably being formed as a flat element. With such orientation of the fastening flap in combination with its preferred flat design, a low level of the force value, at which plastic deformation starts to occur, is realized.
- Moreover, a main direction of extent of the fastening hook may be oriented orthogonally to the mounting plane. Likewise, the fastening hook is preferably formed as a flat element.
- In some implementations, the fastening hook is configured to be inserted in an opening of the casing wall or of the frame or support part. The opening is preferably a slit-shaped opening. A hook end portion of the fastening hook is configured to engage behind the casing wall or the frame or support part. Preferably, the engagement is provided after the fastening hook, more specifically the component or assembly, has performed a sliding movement in a direction parallel to the mounting plane.
- According to a specific embodiment, the hook end portion is arranged at a rear surface of the casing wall or of the frame part at least directly after fastening the component or the assembly at the casing wall or the frame part. Said rear surface faces away from the component or assembly. Further, a gap is formed between the hook end portion and the rear surface and is configured to allow at least a movement of the component or assembly relative to the mounting plane, i. e. relative to the casing wall or to the frame or support part, within the force value range, in which elastic deformation of the first fastening means takes place, or, as preferred, to allow even a movement of the component or assembly relative to the mounting plane within the force value range, in which plastic deformation of the first fastening means takes place. Accordingly, the gap between the hook end portion and the rear surface of the casing wall or of the frame part may define a maximum level of plastic deformation of the first fastening means and/or a maximum relative movement between the component or assembly and the casing wall or the frame or support part.
- One specific solution according to the present invention is characterized in that the first fastening means and/or the second fastening means is/are integrally formed with a housing or a supporting structure of the component or the assembly. That way, no additional component or part is needed, supporting the task of providing a cost-efficient solution.
- Moreover, it may be provided that at least one of the first fastening means and the second fastening means is a metal part, which is preferably produced by a sheet metal punching and forming process. Certainly, also other material, notably any material usually used in the manufacturing of household appliances, may find use as well. More specifically, such material is selectable from a group of plastic, fibre or any similar materials. In order to realize plastic deformation of the first fastening means, it is preferred to use material of low brittleness, or even flexible plastic or fibre material, even though it may not be excluded that a specific shock absorption will be performed by causing fine cracks on the first fastening means. In some implementations, different materials for first and second fastening means are applied, for example using more flexible material for the first fastening means than for the second fastening means. Even more, due to the fact that the household appliance shall be constructed in that way that mechanical stress situation usually occurring during the lifetime of the appliance do not effect any plastic deformation or damage of the second fastening means, it may be possible to use material of high brittleness for this element.
- More specifically, the household appliance is a combination appliance comprising a cooking hob and the component or assembly is an extraction device or a component or assembly of the extraction device, preferably an extraction fan. The component or assembly is particularly attached to a bottom wall of the cooking hob.
- Novel and inventive features of the present invention are set forth in the appended claims.

FIG. 1 illustrates a general setup of astandard combination appliance 10 comprising acooking hob 12 and adowndraft extraction device 14 installed in akitchen cabinet 16. Thecooking hob 12 is implemented in a cut-out of akitchen countertop 18 forming a top cover plate of thekitchen cabinet 16. Thedowndraft extraction device 14 is configured to take away cooking vapours occurring during cooking processes, in particular when cooking with uncovered cookware. Thecooking hob 12 comprisescooking regions cooktop 22 of thecooking hob 12, which left and right halves are separated from each other by asuction opening 24 for an intake of the cooking vapours, thesuction opening 24 being arranged alongside a cooktop centreline. Thesuction opening 24 is covered by acover grid 26 for preventing items, e. g. cookware, to fall into thesuction opening 24. Instead of the cover grid 26 a lid may be used for entirely covering the suction opening when theextraction device 14 is out of use, but for the operation of theextraction device 14 the lid is pivotable into an upright open position. - A
housing 28 of theextraction device 14 is shown inFIG. 1 in transparent illustration. Saidhousing 28 provides a closed outer shell or channel segment for a flow of the sucked-in cooking vapours on their way from thesuction opening 24 to anexhaust opening 30 in abase area 32 of thekitchen cabinet 16. Saidexhaust opening 30 is also covered, namely by anoutlet grille 34. - The flow of the sucked-in cooking vapours through the
extraction device 14 is driven by the operation of anextraction fan 36 arranged inside of thehousing 28. Saidextraction fan 36 comprises a bottom-sided intake opening 38 for sucking the cooking vapours from the interior space of thehousing 28. - A rear-sided fan outlet is arranged for a horizontal exit of the air blown out backwards from the
extraction fan housing 42. The fan outlet is connected to a first end of anair duct 44 designed as a rectangular tube and forms a second channel arranged downstream the above-mentioned first channel. Directly at the passage from the fan outlet to theair duct 44, an air duct bending by 90 degrees is implemented, which redirects the air flow from horizontal to vertical downwards. Theair duct 44 may be guided alongside a rear side of thekitchen cabinet 16 and may be bent again by 90 degrees close to a rear lower edge of thekitchen cabinet 16 in order to direct the airflow towards exhaust opening 30 in thebase area 32 of thekitchen cabinet 16. Accordingly, the second end of theair duct 44 is connected to theexhaust opening 30. The embodiment illustrated inFIG. 1 shows a solution of theair duct 44 with an inclined section of its downwardly directed portion, directed slightly to the right. Naturally, a solution with said portion arranged in an exact vertical direction is considerable as well. - The course of the cooking vapours from the cooking area through the
extraction device 14 to a re-entry into ambient air is illustrated inFIG. 1 by dottedarrows 461 to 465. On their way through theextraction device 14, the cooking vapours pass through afilter assembly 48, which is arranged downstream directly behind thesuction opening 24 for providing a purification of the conveyed air. Saidfilter assembly 48 includes afilter carrier 50 supporting a filter element (not shown) that is usually configured for filtering out grease particles and droplets. - The structure of the
combination appliance 10 with theair duct 44 inside of thekitchen cabinet 16 and theexhaust opening 30 on the front of thecabinet 16 as shown inFIG. 1 is only one installation option. In other exemplary installations, the illustratedair duct 44 may be replaced by a direct blow-out opening at the cabinet rear side through an opening in the rear-sided cabinet wall or by an air channel guided through a wall of the installation location of thecombination appliance 10, e. g. for an air exhaust outdoors. - The cross-sectional view of
FIG. 2 further shows twopower boards 54, one for theleft cooking region 20a and one for theright cooking region 20b, thepower boards 54 providing cooking zones in the left andright cooking regions cooking hob 12 is an induction cooking hob and the cooking zones are defined by induction coils (not shown) that are arranged below thecooktop 22 of thecooking hob 12. Attached to the bottom side of thepower board 54 assigned to theright cooking region 20b, a further circuit board is arranged forming acontrol electronics 56 for thecombination appliance 10. Acooking hob housing 58 encloses the components of thecooking hob 12, specifically saidpower boards 54 and said control electronic 56. As illustrated inFIG. 3 in dotted lines, thecooking hob housing 58 is fixed to thecooktop 22 by screws viabrackets 62, which themselves are attached to the bottom side of thecooktop 22 by gluing. - Furthermore, the
combination appliance 10 is shown in parts inFIG. 3 with a presentation method similar to that one ofFIG. 2 . In contrast to the illustration ofFIG. 2 , the presentation ofFIG. 3 includes the frontal surface of thecombination appliance 10. Moreover, theextraction device housing 28 and thefilter assembly 48 are removed for an increased focus on the present inventive concept. - The
extraction fan 36 is attached to abottom wall 60 of thecooking hob housing 58, which attachment forms a hanging arrangement when thecombination appliance 10 is installed in thekitchen cabinet 16, by means of fastening elements illustrated inFIG. 3 with dotted lines. These fastening elements includehooks 66 and flaps 68, which are arranged at different lateral edges of amotor plate 64. Themotor plate 68, which is shown in isolated illustration inFIG. 5 , forms an integral element, more precisely a top plate, of thefan housing 42 and provides a supporting structure for theentire extraction fan 36. The top surface of the assembledmotor plate 64 entirely abuts against the bottom surface of thebottom wall 60 of thecooking hob housing 58. - The fastening details are generally provided with
FIG. 4 , presenting thecooking hob housing 58 isolated from thecooking hob 12, as well as with detailed illustration according toFIG. 6 showing an enlarged view of detail VI indicated inFIG. 4 .Rectangular openings 70 and slits 72 are implemented in thebottom wall 60 ofcooking hob housing 58, which are configured to receive thehooks 66 and theflaps 68 that are integrally formed, more specifically received by a punching and bending process of a sheet metal, with lateral edges of themotor plate 64. Theflaps 68 are in a stepped arrangement to the main plane of themotor plate 64, so that theflaps 68 are configured to engage behind thebottom plate 60 of thecooking hob housing 58. In a similar way, also thehooks 66 engage behind saidbottom plate 60 after their insertion in therelated slits 72 and a displacement ofmotor plate 64 alongside the bottom surface ofbottom wall 60. In contrast to the engagement of theflaps 68, which provides a touching support on the top surface of thebottom wall 60 at contact surfaces 76, the lower edges of thehooks 66 are spaced from said top surface by forming agap 74 in between after fixation of theentire extraction fan 36 to thebottom wall 60. That way, in normal condition, e. g. directly after the assembly of thecombination appliance 10, and without any shock impact thereon, thehooks 66 do not perform any supporting function. Instead, only after any shock impact onto theappliance 10 such supporting function comes into effect, as will be described in more detail further down below. The enlarged detail view according toFIG. 6 further illustrates that an easy insertion of theflaps 68 is provided by an angledfree edge 78 forming a lead-in chamfer during the assembly process. - The general working concept of the fastening system herein disclosed is as follows. Due to the fact that the
combination appliance 10 comprises heavy components like theextraction fan 36, which are attached to other components like thecooking hob wall 60, there is a risk of damages specifically during transportation or installation of thecombination appliance 10, especially in case of an unintended drop of theappliance 10 causing shocks and related displacement forces acting on the individual components. Rigid connections of these components directly transmit emerging forces caused by these shocks to the parts or components that are connected to them. In the specific case of thecooktop 22 comprising a glass ceramic plate, more specifically having a cutout forming or comprising thesuction opening 24, there is a high risk for damages on the glass material because cut surfaces and edges of glass material provide weak points of the entire element. Usually, such kind of shocks with an impact on glass elements will cause glass breakage. In order to avoid such damages, the herein disclosed combination offlat flaps 68 andrigid hooks 66 dampens such shocks, on the one hand, and, on the other hand, except slight but acceptable displacements, the components stay in their original positions. - In other words, the principal purpose of the specific fastening system provides a combination of one or more
flat flaps 68 and one or more verystrong hooks 66 with orientation orthogonally to the mounting plane, which are arranged on a connection part, specifically on themotor plate 64 of theextraction fan 36. Said hooks 66 and flaps 68 may be positioned in a central area or in a side area of the connection part, or in any position therebetween. There is no limitation or specific preference as to the number ofhooks 66 and flaps 68. In case of shocks, theflat flaps 68 are deformed elastically within the limits of the material properties of the used material, which is preferably a metal. Depending on the shock intensity causing a related relative movement of the component, the result may be only an elastic deformation of theflaps 68. A more enhanced shock intensity inducing a higher relative movement, however, leads to a plastic deformation of theflaps 68, which plastic deformation process includes an increased shock absorption capacity. On the other hand, the vertically oriented hooks 66 allow said relative movement of the component and the related elastic and plastic deformation of theflat flaps 68 within the predefined distance, corresponding to the providedgap 74, only. Moreover, thevertical hooks 66 are sufficiently rigid for keeping the relative movement within said predefined distance. To this end, it is provided that no such shocks and related forces shall be taken into account, which would end up with any plastic deformation of thehooks 66. More specifically, the fastening system is preferably designed in such a way, that drop tests, as required by standards in the household business, will at most lead to plastic deformation of theflaps 68, but will not lead to any plastic deformation of thehooks 66. In the same manner, the shocks during transport and installation may be compensated by elastic and plastic deformation of theflat flaps 68, while the vertically oriented hooks 66 ensure a proper retaining positioning of all components. The includedgap 74 is dependent on the maximum elastic deformation level of the material as well as the distance of thehooks 66 to theflaps 68. - As already indicated above, the fixation system may include a plurality of pairs of cooperating
flaps 68 and hooks 66 in a way that themotor plate 64 is entirely attached by these means to thebottom wall 60 of thecooking hob housing 58. Alternatively, themotor plate 64 may be fastened to thebottom wall 60 of thecooking hob housing 58 on only one side, while the other side of themotor plate 64 may comprise fastening means, e. g. screws and related holes, for a rigid connection to thebottom wall 60 after said displacement of themotor plate 64 alongside the bottom surface of thebottom wall 60, so that the inventive concept will operate only one-sided, which may reduce the protective effect of the fastening system but may nevertheless be a sufficient solution. - All in all, with the disclosed combination of soft first fastening means, which absorb hard shocks, and rigid second fastening means, which keep the attached component in almost unchanged position, the fastening system can be downsized and the number of involved parts can be reduced. No flexible parts like silicone, rubber or springs are necessary as it is provided in solutions known from the prior art. Naturally, in order to further increase the effect as provided by the present invention, such flexible or soft parts might be used in addition. Moreover, the packaging of the
entire combination appliance 10 for its safe transportation may be designed less complex and in a more cost-efficient way. - Finally, although a
combination appliance 10 with specific dimensions is presented byFIGs. 1 to 6 , the herein described setups ofcombination appliance 10 may be applicable to all known sizes ofcooking hobs 12 andrespective combination appliances 10 with a width of at least 580 mm. Two, three or four cooking zones may be provided, specifically depending on the size of thecooking hob 12. - Although illustrative embodiments of the present invention have been described herein with reference to the accompanying drawings, it is to be understood that the present invention is not limited to these precise embodiments, and that various other changes and modifications may be affected therein by one skilled in the art without departing from the scope or spirit of the invention. All such changes and modifications are intended to be included within the scope of the invention as defined by the appended claims.
- Moreover, features which are described in the context of separate aspects and embodiments of the invention may be used together and/or be interchangeable. Similarly, features described in the context of a single embodiment may also be provided separately or in any suitable sub-combination.
