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 cooktops to suck in the vapors rising during cooking and in particular to free them of fat components. The cleaned air is then either discharged as exhaust air from the kitchen or blown back into the kitchen in a recirculation mode.
  • Extractor hoods for recirculation mode are known from the publication EP 2 498 006 A1 and from the publication 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, for example activated carbon filters.
  • filters for example activated carbon filters.
  • the air flow through the fan is passed or pressed through such a filter before it leaves the extractor hood.
  • extractor hoods with a round or rounded cross-section or housing, as described in the document DE 10 2012 022 571 A1 or the publication EP 3 163 175 A1 or the publication CN 108 592 116 A are known, often offer very poor or uncomfortable access to the filters.
