Definitions

  • the present invention relates to a combination appliance comprising a cooking hob and an extraction device for removing air, specifically cooking vapours, from an area above the cooking hob according to the preamble of claim 1.
  • the present invention further relates to a method for assembling a combination appliance comprising a cooking hob and an extraction device according to claim 11.
  • Such kind of extraction device is usually arranged below a worktop of the related cooking hob and it comprises at least one fan for sucking air from the cooking area through an opening arranged in the worktop.
  • Such a configuration of a cooking hob and an extraction device being connected together in a combined arrangement is commonly called a combination appliance.
  • DE 10 2017 121367 A1 discloses the preamble of claim 1, disclosing a downdraft extractor hood with an air conveying channel having a box-shaped design and being positioned below a cooking surface.
  • the air conveying channel is vertically arranged and includes two channel halves, which each communicate in a lower lateral area with an exhaust air suction chamber.
  • a bottom wall of the air conveying channel is arranged in close proximity to a bottom wall of the exhaust air suction chamber.
  • US 2018/229171 A1 discloses a filter unit for a fume extraction device of a combination appliance, also comprising a cooktop.
  • the fume extraction device includes a filter unit with a filter element and a collection region partially surrounding the filter unit for collecting a liquid.
  • the collection region is formed in an overflow container, which is fixedly connected to the cover plate of the cooktop. Between the overflow container and the cover plate of the cooktop, a sealing ring is provided, which is received in a sealing slot on an upper edge of the overflow container.
  • DE 10 2016 130828 A1 discloses an extractor hood for the extraction of fumes below a hob plate through a suction opening.
  • An air conveying channel is positioned below the suction opening.
  • the air conveying channel includes a filter element for the filtration of the air stream. After passing the filter element, the air stream leaves the air conveying channel through an air outlet opening at a lower section of a channel side wall and is forwarded to a fan, which is configured to produce the airflow.
  • a combination appliance in particular for domestic use, comprises a cooking hob and an extraction device.
  • the cooking hob configured for cooking a food item thereon, is covered by a top plate or a worktop, which may be a glass plate.
  • the top plate or worktop includes an opening or a recess that is formed therein providing a passage through the top plate or worktop.
  • the extraction device is arranged below the top plate or worktop and comprises at least one fan for sucking air from an area above the cooking hob through the opening or recess of the top plate or worktop and for conveying the air through an air channel of the extraction device.
  • the air channel of the extraction device includes a channel section, which is arranged downstream of the opening or recess and upstream of the fan.
  • the channel section is further arranged adjacent to components, in particular electrical and/or electronic components, of the cooking hob. More specifically because of an impenetrable wall, the channel section forms a barrier for the prevention of the conveyed air to get in contact with the components of the cooking hob.
  • the channel section comprises an upper portion and a lower portion.
  • the upper portion which is particularly a top edge or top surface, abuts a surface zone of the top plate or worktop, particularly of the bottom of the top plate or worktop.
  • the lower portion which is particularly a bottom surface, abuts and/or is supported by a wall section of the cooking hob.
  • Said wall section is in particular a bottom wall section or a side wall section or an intermediate wall section.
  • the cooking hob being the source for the aspirated cooking vapours may be of any type including electric or gas cooking hobs.
  • the electric cooking hob is an induction cooking hob.
  • the cooking hob may further be an autarkic cooking appliance, particularly integrated in a countertop of kitchen furniture, or it may be part of a stove.
  • a top surface of the top plate or worktop, which is accessible to a user, may be used for putting cookware thereon, specifically in order to perform a cooking process.
  • the cooking hob preferably comprises at least one heating element defining a cooking zone on the worktop or, specifically, the glass plate, which is favourably made out of glass ceramics.
  • One particular advantage of the solution according to the present invention is the fact that the top surface of the top plate or worktop is entirely kept in a flat execution and there are no obstacles provided to the user of the appliance, when moving the cookware along the cooking surface.
  • Said channel section particularly also further sections of the air channel, may be made in plastic or any other suitable material, e. g. sheet metal.
  • the extraction device comprises an exhaust opening for blowing out the air into the atmosphere.
  • Said exhaust opening is notably arranged at the end of the air channel downstream of the fan.
  • at least one filter element or a filter unit may be arranged in the extraction device, more specifically in the path of the air stream, particularly inside of the air channel.
  • a preferred embodiment of the present invention provides for a sealing means, which is arranged or arrangeable at the upper portion of the channel section, in particular between the upper portion and the surface zone of the top plate or worktop. Additionally, or alternatively, the sealing means may be arranged or arrangeable at the lower portion of the channel section, in particular between the lower portion and the wall section of the cooking hob. Said sealing means are adapted to hermetically seal the cooking hob, in particular components of the cooking hob, off from the air conveyed through the air channel. This allows an entire aspiration of the cooking vapours through the opening or recess and prevents any air bypass.
  • One specific solution for the sealing means comprises a layer of glue, which is particularly a circumferential glue bead applied on or contacting the upper portion of the channel section.
  • the upper portion of the channel section preferably surrounds a cross-sectional area of the interior space of the channel section. More preferably, the upper portion of the channel section surrounds a wall of the channel section.
  • An entirely circumferential glue spread surrounding the interior of the channel section not only cares for a fixed connection between the top plate or worktop and the channel section, but also avoids any air bypass and allows to skip any specific additional sealing means.
  • the upper portion of the channel section may comprise a circumferential rim or collar laterally protruding from the channel section wall.
  • the circumferential rim or collar and the bottom of the top plate or worktop are preferably aligned parallel to one another. Additionally, or alternatively, the circumferential rim or collar are preferably arranged or arrangeable spaced from the bottom of the top plate or worktop.
  • the space between the circumferential rim or collar and the bottom of the top plate or worktop particularly forms a receiving space for the layer of glue. That way, the layer of glue is not squeezed out at any point of the area or its application, which would entail the risk of air leakage at a point without gluing.
  • the channel section comprises a pipe section, which includes an insertion space for housing a filter element or a filter unit.
  • the channel section and/or pipe section may have any shape with an arbitrary cross section, however, a rectangular cross section, is a preferred solution for such section(s).
  • the channel section may comprise a supporting means, notably a first supporting means, or a fixation means for a, preferably releasably, fixed positioning of a filter element or a filter unit.
  • a supporting means notably a second supporting means, for supporting a grid or a lid adapted to cover the opening or recess may be included.
  • Said second supporting means is particularly a supporting surface or supporting frame or supporting element.
  • the extraction device may also be characterized by an outlet port of the channel section, which opens out into a suction compartment arranged downstream thereof and upstream of the fan.
  • a circumferential protection edge is arranged at the upper portion of the channel section, which protection edge abuts lateral edges of a cutout of the top plate or worktop, wherein the cutout is specified by the opening or recess.
  • the cutout is rectangular, specifically when also the channel section is of a rectangular shape.
  • the protection edge is arranged at an inlet port located at the opening or recess, thus protecting the edges of the cutout from any mechanical damages.
  • the combination appliance is advantageously characterized by a wall of the channel section, which comprises a double-walled structure including an inner channel section wall and an outer channel section wall. Moreover, the inner channel section wall opens out into a suction compartment arranged downstream thereof and upstream of the fan and particularly penetrates the bottom wall.
  • the outer channel section wall is preferably supported by the bottom wall section of the cooking hob.
  • Supporting ribs may be arranged between the inner channel section wall and the outer channel section wall. Said supporting ribs are particularly orthogonally arranged to the inner and outer channel section walls.
  • a lower portion, which is a lower end surface, of the channel section wall is supported by a bottom wall section of the cooking hob.
  • Said bottom wall section is more specified by a protrusion of the bottom wall protruding from a box or a compartment defined by walls, which comprise the bottom wall and a side wall adjacent to the channel section wall.
  • the bottom wall section is a circumferential edge of a cutout in the bottom wall.
  • the object is further achieved for a method for assembling a combination appliance comprising a cooking hob and an extraction device according to the features of claim 11.
  • a method for assembling a combination appliance comprising a cooking hob and an extraction device, comprises at least a first and a second assembly step.
  • a channel section of an air channel of the extraction device is connected to a top plate or worktop of the cooking hob in a way that an inlet port of the channel section is assigned to an opening or recess formed in the top plate or worktop.
  • the connection between channel section and top plate or worktop is preferably performed in an airtight, i. e. hermetical, manner. More preferably, the channel section is glued on the top plate or worktop.
  • the top plate or worktop is positioned on a substructure, in particular on a lower hob box, of the cooking hob.
  • the channel section is arranged alongside the substructure or penetrates the channel section, so that, as a result, the channel section extends from the opening or recess of the top plate or worktop to or through a bottom wall, in particular to or through a cutout in the bottom wall, of the cooking hob.
  • an outlet port of the channel section opens out or is provided to open out into a suction compartment of a fan of the extraction device.
  • Said fan is configured for sucking air from the area above the cooking hob through the opening or recess of the top plate or worktop and for conveying the air through an air channel of the extraction device.
  • the suction compartment of the fan is arranged beneath the cooking hob in an assembly step prior to the first step, between first and second steps or after the second step.
  • the first assembly step may be performed at an installation location different from that one of the second assembly step.
  • the first assembly step may be executed on a pre-assembly line.
  • the channel section is connected during the first step to the top plate or worktop in a way that the central axis of the channel section passes through the centre of the opening or recess. That way, full alignment between the two involved components is established.
  • a glue bead may be circumferentially applied on an upper portion, in particular on a top surface or top edge, of the channel section.
  • the upper section preferably surrounds a cross-sectional area of the interior space of the channel section. More preferably, the upper section surrounds a wall of the channel section.
  • the glue bead may by circumferentially applied on a border around the opening or recess of the bottom side of the top plate or worktop. More specifically, after said application of the glue bead, a glued joint is established between the upper portion of the channel section and the top plate or worktop. Said glue bead is not only provided for establishing a fixed connection, but also works as a sealing means for preventing air to pass through the respective junction.
  • the lower portion of the channel section is set down during the second step on the bottom wall of the cooking hob. This joining of the two components is performed in particular in a final stage of the second step. On this occasion an at least approximately airtight junction is preferably established at the contact zone.
  • Said lower portion may be a bottom surface or bottom edge of the channel section.
  • Fig. 1 illustrates a combination appliance 10 comprising a cooking hob 12 and a downdraft extraction device 14 installed in a kitchen cabinet 16.
  • the cooking hob 12 is implemented in a cutout of a kitchen countertop 18 forming a top cover plate of the kitchen cabinet 16.
  • the downdraft extraction device 14 is configured to take away cooking vapours occurring during cooking processes, in particular when cooking with uncovered cookware.
  • the cooking hob 12 comprises cooking regions 20a, 20b arranged on a left half and a right half of a cooktop 22 of the cooking hob 12, which left and right halves are separated from each other by a suction opening 24 for an intake of the cooking vapours, the suction opening 24 being arranged alongside a cooktop centreline.
  • the suction opening 24 is covered by a cover grid 26 for preventing items, e. g. cookware, to fall into the suction opening 24.
  • a lid may be used for entirely covering the suction opening when the extraction device 14 is out of use, but for the operation of the extraction device 14 the lid is pivotable into an upright open position.
  • the flow of the sucked-in cooking vapours through the extraction device 14 is driven by the operation of an extraction fan 36 arranged inside of the casing 28.
  • Said extraction fan 36 comprises a bottom-sided intake opening 38 for sucking the cooking vapours from the interior space of the casing 28.
  • a rear-sided fan outlet (not shown) 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 an air duct 44 designed as a rectangular tube and forms a second channel arranged downstream the above-mentioned first channel.
  • an air duct bending by 90 degrees is implemented, which redirects the air flow from horizontal to vertical downwards.
  • the air duct 44 may be guided alongside a rear side of the kitchen cabinet 16 and may be bent again by 90 degrees close to a rear lower edge of the kitchen cabinet 16 in order to direct the airflow towards exhaust opening 30 in the base area 32 of the kitchen cabinet 16.
  • the second end of the air duct 44 is connected to the exhaust opening 30.
  • the embodiment illustrated in Fig. 1 shows a solution of the air 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.
  • a filter assembly 48 which is arranged downstream directly behind the suction opening 24 for providing a purification of the conveyed air.
  • Said filter assembly 48 includes a filter carrier 50 supporting a filter element (not shown) that is usually configured for filtering out grease particles and droplets.
  • the cross-sectional view of Fig. 2 further shows two power boards 54, one for the left cooking region 20a and one for the right cooking region 20b, the power boards 54 providing cooking zones in the left and right cooking regions 20a, 20b with electrical power.
  • the cooking hob 12 is an induction cooking hob and the cooking zones are defined by induction coils (not shown) that are arranged below the cooktop 22 of the cooking hob 12. Attached to the bottom side of the power board 54 assigned to the right cooking region 20b, a further circuit board is arranged forming a control electronics 56 for the combination appliance 10.
  • Fig. 3 illustrates a cross-sectional view of the upper section of the combination appliance 10 representing the area of localisation of the cooking hob 12. This means, that the combination appliance section beneath the cooking hob 12 is cut away.
  • the viewing direction providing the illustration of Fig. 3 is shown in Fig. 2 .
  • the presentation according to Fig. 3 represents the status of the filter assembly 48 being removed from its operating position according to Figs. 1 and 2 and shows a vertical cross-section through an initial channel section 58.
  • the initial channel section is formed as a pipe section with a rectangular horizontal cross-section, which is defined by its front and rear (from user's perspective) channel walls 58a as well as its lateral channel walls 58b, the channel walls 58a, 58b forming a cuboid tube, with an inlet opening directly downstream of the suction opening 24 and an outlet opening opening out into the interior of the casing 28, which is a subsequent air channel segment directly downstream of the initial channel section 58.
  • the casing 28 also works as a suction compartment, which provides the conveyed air to the fan 36 that aspirates the air through the intake opening 38.
  • the filter assembly 48 is not present, however, the suction opening 24 is covered with grid 26.
  • the initial channel section 58 On its bottom side, defining also the outlet opening, the initial channel section 58, more precisely the channel walls 58a, 58b of the channel section 58, rests on a bottom wall 60 of the cooking hob 12.
  • the top sides of the channel walls 58a, 58b of the initial channel section 58 abut with their upper front faces a border around the suction opening 24 on the bottom surface of the cooktop 22. That way, the initial channel section 58 is sandwiched between the upper side of the bottom wall 60 of the cooking hob 12 and the bottom side of the cooktop 22.
  • sealing means are arranged between the initial channel section 58, on the one hand, and the bottom surface of the cooktop 22 as well as the bottom wall 60 of the cooking hob 12, on the other hand.
  • the sealing means on the top side of the initial channel section 58 is realized by a circumferential glue bead 62 continuously surrounding the upper front faces of the channel walls 58a, 58b of the initial channel section 58.
  • the upper portion of the initial channel section 58 comprises a circumferential rim 64 laterally protruding from the upper end of the channel walls 58a, 58b.
  • the circumferential rim 64 and the bottom surface of the cooktop 22 are aligned parallel to one another and the circumferential rim 64 is arranged spaced from the bottom surface of the cooktop 22, wherein the space between the circumferential rim 64 and the bottom surface of the cooktop 22 forms said receiving space for the glue bead 62.
  • the sealing on the bottom side of the initial channel section 58 according to the embodiment of Figs 3 and 4 is simply realized by a firm touching or pressing of the lower front faces of the channel walls 58a, 58b of the initial channel section 58 onto the upper side of the bottom wall 60 of the cooking hob 12, or more precisely, on a border around a cutout in the bottom wall 60 adjacent to the outlet opening of the initial channel section 58, which cutout provides a passage for the conveyed air from the initial channel section 58 to the interior of the casing 28.
  • Figs. 5 and 6 illustrate a second example of the initial channel section 58.
  • the initial channel section 58 comprises a double-walled structure including an inner channel section wall 66a and an outer channel section wall 66b.
  • both inner and outer channel section walls 66a, 66b comprise four single walls, analogous to front and rear walls 58a and lateral walls 58b of the above-described first example.
  • the inner channel section wall 66a opens out into the casing 22 and penetrates the bottom wall 60 of the cooking hob 12, thereby protruding somewhat from the lower surface of the bottom wall 60.
  • the outer channel section wall 66b rests on the bottom wall section of the cooking hob 12.
  • the sealing effect of the second example is increased by an arrangement of two such minimized gaps in series, i. e. both the inner channel section wall 66a and the outer channel section wall 66b of the double-walled channel section about the bottom wall 60 of the cooking hob 12, either on the top surface of the bottom wall 60 (see outer channel section wall 66b) or laterally against the cutout edge (see inner channel section wall 66a).
  • This way of two contacting areas with only small gaps implemented in series increase the sealing effect.
  • supporting ribs 68 are arranged between the inner channel section wall 66a and the outer channel section wall 66b. Said supporting ribs 68 are orthogonally arranged to the inner 66a and outer 66b channel section walls. Further supporting ribs 68 are arranged at the outer surface of the outer channel section wall 66b, which are adapted to rest against an inner wall 70 of the cooking hob 12.
  • a third example of the initial channel section 58 is shown.
  • the embodiment according to this third example is almost entirely congruent with the embodiment of the first example (see particularly Fig. 3 ).
  • the only difference to the first example concerns a circumferential protection edge 72, which is arranged at the inlet port located at the suction opening 24 of the channel section 58.
  • the protection edge 72 abuts against lateral edges of the cutout of the glass cooktop 22, which cutout is specified by the suction opening 24. Due to its function of covering said cutout edges, the circumferential protection edge 72 thus protects these cutout edges from any mechanical damages.
