Apparatus for discharging smokes, fumes and greases from kitchens

Abstract

The invention relates to a new device for discharging smokes, fumes and greases from various indoor premises and comprising a set of ceiling elements arranged with smoke, fumes and grease discharging slits therebetween. It is characterized in that the ceiling elements it includes are hollow and crossed by water whose circulation is ensured by pipes interconnecting the elements, which elements form condensers with water-cooled heat-transfer surfaces. Discharging of the grease deposits collected on the condensers is effected by washing with water containing a detergent, this water being supplied by spray-rails, while the washing water and the dissolved greases are collected by the drains. Hoods are provided above the slits separating the drains (the later being close to one another) in order to completely secure the premises against dripping of the greases and washing water during the cleaning operation, which is performed only when it proves necessary.
