Definitions

  • the present invention relates to an extractor hood comprising at least one housing device with at least one treatment section with a round cross section.
  • the housing or the treatment section comprises at least one inlet opening for sucking in vapors and at least one outlet opening for blowing out treated air.
  • the present invention also relates to a method for changing filter units in such an extractor hood.
  • Extractor hoods are often used in kitchens above hobs in order to suck in the vapors that rise during cooking and in particular to free them from fat components.
  • the cleaned air is then either discharged from the kitchen as exhaust air or blown back into the kitchen in a recirculation mode.
  • Extractor hoods for air recirculation are known from the publication EP 2 498 006 A1 and from the pamphlet DE 10 2017 100 855 A1 .
  • Odor pollution in recirculation mode can be achieved, for example, by means of odor-absorbing and/or neutralizing filters, such as activated carbon filters.
  • filters such as activated carbon filters.
  • the air flow through the fan is directed or pressed through such a filter before leaving the extractor hood.
  • the extractor hood comprises at least one housing device with at least one treatment section with at least one round cross section.
  • the housing device or the treatment section has at least one inlet opening for sucking in vapors and at least one outlet opening for blowing out treated air.
  • at least one essentially flow-tight separating device is arranged in the processing section, which divides the processing section into at least one lower inlet section with the inlet opening and at least one upper blow-out section with the outlet opening.
  • An essentially flow-tight separating device is designed in such a way that a maximum of 10 percent of the air flow to which it is exposed bypasses the separating device as leakage air flow.
  • At least one passage is provided in the separating device as a connection between the lower inlet section and the upper blow-out section, with at least one fan device being arranged on the passage, which draws in air from the inlet opening and blows it out in the direction of the outlet opening.
  • at least one essentially ring-shaped receiving space for accommodating at least two filter units, which is accessible at least in sections via at least one recess in the separating device in order to remove the filter units through this recess and/or use.
  • the term essentially ring-shaped is to be understood in such a way that the figurative-technical term ring is not only reduced to a circular ring, but also includes other basic ring shapes. Neither is the relationship between the distance from the inside of the ring to the center and the distance from the outside of the ring to the center defined.
  • the extractor hood according to the invention is in particular an extractor hood which is suitable or designed exclusively or also alternatively for recirculation mode.
  • the filter units which can be inserted into the essentially ring-shaped receiving space, are preferably designed as odor filters and such odor filters, for example activated carbon filters, remove odors from the air that has already been cleaned by grease filters, which is particularly important when the air is blown back into the kitchen during recirculation mode is advantageous.
  • the housing device or the processing section has a round cross section.
  • the processing section preferably has a substantially cylindrical shape, at least in sections.
  • a dome-shaped configuration of the housing device or the extractor hood or the processing section is also preferred.
  • an essentially cylindrical shape can also include conical or asymmetrical spatial bodies.

  • blower device is arranged at the passage means in particular that the blower device is directly or indirectly operatively connected to the opening or the passage, so that the blower device can convey air from the inlet opening to the outlet opening.
  • the blower device is positioned above the passage on or on the separating device and is preferably fastened to the separating device.
  • the annular receiving space is preferably delimited by the housing device in the blow-out section and the blower device arranged in the blow-out section.
  • the annular receiving space preferably extends around the blower device.
  • the blower device Since the blower device is arranged in the upper exhaust section, the blower device preferably sucks rising fumes through a grease filter arranged in or at the inlet opening into the extractor hood or into the preparation section and forces the air, which has already been cleaned of grease components, through the air that is arranged in the annular receiving space Filter units, which are designed in particular as odor filters. In this way, a particularly advantageous air flow is achieved by means of the blower device.
  • the recess in the separating device is preferably provided in such a way that the filter units movable in the circumferential direction in the receiving space can be inserted into and removed from the annular receiving space substantially transversely to the radius of the annular receiving space, i.e. in the axial direction.
  • the specification essentially transverse to the radius is not limited to a strict geometric movement perpendicular to the radius, but includes different orientations in a common handling space.
  • the tolerance includes a deviation of up to 60°.
  • the recess in the separating device via which access to the annular receiving space is provided, can be closed so that during normal operation of the extractor hood the entire air flow is reached through the passage in the separating device via the blower device.
  • the recess is then only opened when a filter unit is to be removed from the annular receiving space or when a filter unit is to be changed.
  • the recess can also be closed again by means of a closure device.
  • At least one grease filter is preferably provided on or in the inlet opening.
  • the rising vapor is freed from grease components.
  • Such a grease filter can preferably be accommodated in a visually appealing decorative panel, with the removal of the decorative panel preferably simultaneously removing the grease filter or filters so that they can be easily cleaned or replaced.

  • a significant advantage is that the separating device forms an upper and a lower section in the processing section, so that the processing section is divided into a suction side and a pressure side for the blower device.
  • the fan sucks rising fumes through the grease filter and then pushes the sucked air through the other filter units, in particular through the odor filter. This results in a particularly favorable flow behavior reached.
  • the configuration of the upper blow-out section as an annular receiving space with the recess for removing and inserting filter units ensures particularly favorable accessibility to the filter units.
  • At least one driver device is provided in the upper blow-out section in order to displace the filter units within the annular receiving space, in particular to move them from an inaccessible area of the annular receiving space to the recess.
  • the driver device is provided to transport inaccessible filter units to the recess for removing the filter units from the annular receiving space.
  • the shifting of the filter units by means of the driver device can be motorized or achieved automatically and/or manually, depending on the configuration.
