Definitions

  • the invention relates to an extractor device for a kitchen appliance according to the preamble of claim 1.
  • a suction shaft running along one side of the kitchen appliance with a long, narrow suction opening and a fan connected to it via flexible air lines.
  • suction shafts running along both sides of the hob, which lead via pipes into a fan in a base cabinet.
  • This known device has the disadvantage that it takes up a lot of space in the kitchen appliance below the hob and allows no or only very limited usable space for drawers, shelves and similar devices.
  • the invention is based on the object of developing an extractor device of the type mentioned at the outset in such a way that with it the structure of the kitchen appliance below the hob is hardly affected spatially or functionally and a full, unrestricted extraction capacity can also be guaranteed.
  • the fact that the vapors are sucked down from the hob means that the vapors that arise on the hob during the cooking process and rise from the cooking items in the cookware on the hob are reversed and sucked off under a storage level formed by the hob.
  • the upper suction opening of the extractor device is preferably arranged in the storage level defined by the hob.
  • the rest of the structure of the extractor device is advantageously arranged below the storage level of the hob.
  • Both the suction shaft and the housing of the suction fan are each dimensioned with a narrow, elongated cross section.
  • the cross section of the suction shaft and also the cross section of the housing of the suction fan are adapted to the shape of the upper suction opening. This means that the cross section of the suction shaft essentially corresponds to the cross section of the upper suction opening.
  • the housing of the suction fan also has a cross section which is matched to the cross section of the suction opening and to the cross section of the suction shaft.
  • the housing of the suction fan advantageously extends below the elongated suction opening, so that the overall width of the housing corresponds to the length of the suction opening.
  • the overall length of the housing is advantageously approximated to the width of the elongated suction opening, so that the suction shaft and the housing protrude only slightly into the interior of the kitchen appliance when installed.
  • the suction fan with its housing is advantageously composed of a backward-curved radial impeller and a central drive motor rotating this radial impeller. This enables a maximum suction power to be achieved that fully meets the requirements.
  • the ring channel surrounding the exhaust fan radially enables particularly compact and uniform air guidance of the air conveyed via the radial impeller into an exhaust channel.
  • the ring-shaped ring channel surrounding the radial impeller enables the air conveyed from the suction shaft via the backward-curved guide vanes of the radial impeller to move evenly outwards along the entire radius around the radial impeller, before the air is deflected in the ring channel and directed into the exhaust channel.
  • the suction shaft provided with the suction opening formed above and the housing of the suction fan are very advantageously installed in the kitchen appliance separately from the hob so that both the hob and the extractor device can be dimensioned or installed or replaced independently of one another.
  • this makes it possible to design the kitchen appliance with negligible restrictions independently of the extractor device.
  • the device according to the invention is easily accessible and, if necessary, can easily be replaced in the event of a defect.
  • suction shaft and the housing of the suction fan lie directly next to one another with their wider sides and are separated by a partition with the central transverse passage opening.
  • the direct arrangement of the suction shaft next to the housing of the suction fan enables a compact structure, since the suction shaft is guided along the housing of the suction fan to the passage opening in the partition between the housing of the suction fan and the suction shaft.
  • the suction duct opens directly into the housing of the suction fan via the passage opening in the partition, since the passage opening in the partition simultaneously forms the suction opening of the housing for the suction fan.
  • the invention also provides that the exhaust duct on the floor of the kitchen appliance standing on it runs flat in a preferably horizontal plane and is provided there with an odor filter which is also preferably flat.
  • the extractor device according to the invention can be installed in different arrangement variants.
  • a first variant it is provided that the suction opening extends along the rear longitudinal edge of the hob.
  • the arrangement is chosen so that the suction opening runs along at least one of the side edges of the hob, the adjoining suction shaft with the suction fan being able to be built into the kitchen appliance as a side wall freely accessible from the outside.
  • This in Fig. 1 kitchen appliance 1 shown is equipped with a hob 2 and it is designed as a piece of furniture standing on feet 1 ', which has a plurality of pull-out drawer fronts 21, 22 and handles 21' assigned to them and in the interior 14 with corresponding drawers 23, 24 is equipped.
  • this kitchen appliance can be designed differently and installed as part of a kitchen island or on the wall side between pieces of furniture or cupboards arranged next to one another. It can also be installed at a hotplate in any room or anywhere else.
  • an extractor device 3 is provided with a narrow, elongated, upper suction opening 4 running along an edge of the hob 2 with a suction shaft 6 forming this and a suction fan 7 having a housing 10.
  • This housing 10 comprises an annular duct 10 ′ which radially surrounds the suction fan 7 and an exhaust duct 11 adjoining it.
  • the suction duct 6 and the housing 10 of the suction fan 7 with the annular channel 10 ' are arranged directly next to one another in this extractor device 3 and they are each dimensioned with a narrow elongated cross-section, which are adapted to the upper suction opening 4. They are each box-shaped and connected by a central transverse passage opening 13 for the flow of the cooking vapors to be cleaned.
  • This suction shaft 6 and the housing 10 lie directly against one another with their wider opposite sides and are separated from one another by an intermediate wall 12 having the central transverse passage opening 13.
  • the partition can also be provided in two parts, both in the case of the suction shaft 6 and in the case of the housing 10.
  • These narrow elongated cross-sections of the suction shaft 6 with the opening 6 'formed and the housing 10 of the suction fan 7 are each essentially rectangular and the ratio of the horizontal length to the width at the top of the suction opening 4 is in each case a multiple, for example 25: 1. Depending on requirements, this can preferably be selected between 5: 1 and 30: 1.
  • the horizontal length of the suction shaft 6 is expediently dimensioned at the top to be the same as that of the suction opening 4, so that the suction power takes place uniformly over the entire length of the latter.
  • This narrow side of the suction shaft 6 together with the housing 10 is preferably dimensioned with an overall depth of between 90 to 160 mm.
  • Both of the box-shaped sections formed by the suction shaft 6 and the housing 10 protrude only slightly into the interior space 14 of the kitchen appliance 1 in the installed state. On the other hand however, they have a very large overall width, which corresponds approximately to the length of the suction opening 4. As a result, the required suction capacity can be achieved despite the very narrow design.
  • the suction fan 7 is provided within the scope of the invention with a radial impeller with backward-curved guide vanes and a drive motor 8 that rotates, preferably an electric motor, this drive motor 8 being arranged in the center of the housing 10 and thus integrated in the suction fan 7 in a very space-saving manner.
  • This suction fan 7 is used to convey the fumes to be extracted from the suction shaft 6 through the passage opening 13 and then radially outward into an annular channel 10 ′ of the housing 10 and from there into the exhaust channel 11.
  • the downwardly running exhaust duct 11 is provided laterally at the end of the housing 10 of the suction fan 7 with an angled connection piece 15 with bending elements 16, 17 and an adjoining odor filter 5, which when installed are aligned along the underside of the kitchen appliance 1 and are accordingly provided for circulating air .
  • This angled connection piece 15 and the odor filter 5 are also provided with a narrow elongated cross section and run transversely to the housing 10 in a horizontal plane. With the arrangement of their narrow sides in the vertical direction, as in Fig. 1 As can be seen, they can be guided under the kitchen appliance and therefore require little space.
  • the bending elements 16, 17 of the angled connection piece 15 are preferably angled air shafts.
  • the odor filter 5 can advantageously under a storage space 15 of the Kitchen appliance 1 are arranged so that the odor filter is located in the area of the feet 1 'of the kitchen appliance 1.
  • the suction opening 4 of a channel 20 is approximately aligned with the wall-shaped outside of the housing 10 of the suction fan 7, as also in FIG Fig. 1 can be seen.
  • the suction shaft 6 extends in a Z-shape, starting from the suction opening 4 above the housing 10, transversely and consequently correspondingly vertically downwards.
  • the extractor device 3 forms a structural unit which can be produced independently of the kitchen appliance 1 and which as such can be installed in the appliance 1 in a few simple steps without interfering with the overall structure of the appliance.
  • support elements 18, 19 are provided on both sides of the suction shaft 6, for example, which can be fastened to the floor of the kitchen appliance standing thereon.
  • This suction opening 4 extends parallel behind the rear longitudinal edge 2 'of the hob 2.
  • the suction duct 6 with the suction fan 7 connected to it is arranged in such a way that it forms the rear of the kitchen appliance 1 when installed.
  • the invention is sufficiently demonstrated with the above embodiment.
  • the extractor device according to the invention could, however, also be installed laterally next to the hob of the kitchen appliance.
  • an extractor hood device could be installed on both sides of the kitchen appliance and, if required, also on the back or on the sides and back.
  • the outside of the hob could have a shape other than rectangular, for example rounded or elliptical. Accordingly, the suction opening would preferably be adapted to this outer shape of the hob and the suction shaft would also be correspondingly shaped in the same way at the top and would then merge into this box shape running vertically downwards as shown.
  • connection piece 15 would then have to lead laterally away from the exhaust duct 11 accordingly.
  • a line could also be led to the outside from the connection piece as exhaust air.
