Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
An installation for discharging smoke, fumes and greases from various premises, more particularly from restaurant or community kitchens comprising a set of hollow ceiling elements each shaped as a long hollow gutter tile having its concave surface facing downwardly and having slits therebetween for discharging smoke and fumes, a water circulation pipe system, piping means connecting said hollow elements for passage of water between and through said elements, and connected to said water circulation pipe system, drains extending beneath said hollow elements with slits between said drains for the passage of smoke and fumes therebetween, said drains connected to a sewer, said hollow ceiling elements forming water-cooled condensers having heat-transfer surfaces for collecting the grease for discharge by said drains.
Claim 2
Dependent Claim
120 words
An installation for discharging smoke, fumes and greases from various premises, more particularly from restaurant or community kitchens comprising a set of hollow ceiling elements each shaped as a long hollow gutter tile having its concave surface facing downwardly and having slits therebetween for discharging smoke and fumes, a water circulation pipe system, piping means connecting said hollow elements for passage of water between and through said elements, and connected to said water circulation pipe system, drains extending beneath said hollow elements with slits between said drains for the passage of smoke and fumes therebetween, said drains connected to a sewer, said hollow ceiling elements forming water-cooled condensers having heat-transfer surfaces for collecting the grease for discharge by said drains.
Claim 3
Dependent Claim
54 words
An installation as claimed in claim 1, further comprising: a discharge chimney; flues located over said ceiling elements for directing the smokes and fumes into said discharge chimney, said flues being tiered and their respective passageway sections being calculated for increasing size according to the increasing distance of their offtake points from said chimney.
Claim 4
Dependent Claim
35 words
An as claimed in claim 1, further comprising: a kitchen hot-water installation, said cooling-water circulating pipes being caused to communicate with said hot-water installation, whereby the same recovers the heat transferred to the cooling water.
Claim 5
Dependent Claim
64 words
An installation as claimed in claim 1, further comprising: said slits provided between said drains, which drains are close to one another, the successive passages of the smokes and fumes through these slits and thereafter through said slits provided between said condenser ceiling elements, causing a slowing down of said smokes and fumes, thereby to assist the depositing of greases on said ceiling elements.
Claim 6
Dependent Claim
31 words
An installation as claimed in claim 1, further comprising: vents providing an additional passage for the smokes and fumes, which vents are provided in and extend through said condenser ceiling elements.
Claim 7
Dependent Claim
23 words
An installation as claimed in claim 1, wherein the longitudinal edges of said condenser ceiling elements are tapered in order to assist dripping.
Claim 8
Dependent Claim
81 words
An installation as claimed in claim 1, further comprising: said slits provided between said drains, which drains are close to one another; spray-rails, usable only for occasional washing purposes, arranged beneath said condenser ceiling elements; spray-rails for washing purposes only, arranged above said slits separating said condenser ceiling elements, the washing liquid and the dissolved greases being collected by said drains; hoods provided above said drain separating slits in order to secure the premises against dripping of greases and washing water.
