  • the evacuation air 39 inlet 22 emerge into the contraction 26.
  • Fig 3 shows in detail the evacuation air 39 inlet 22 situated inserted inside the exhaust air duct 38.
  • the evacuation air duct 39 reduces area from the exhaust air duct 38 wherein a contraction 26 with increased air speed comes up.
  • the central position of the inlet 22 in the exhaust air duct gives favourable conditions for the evacuation air to flow into the exhaust air duct.
  • Fig 4 shows in detail in a cross section how the evacuation air duct 39 in the example fig 3 has been furnished with a tightening 27 in the end and apertures 28 in the walls of the duct 39 in the length inside the exhaust air duct 38.
  • the location of the apertures 28 for the exhaust air gives outflow inside the contraction 26 which has formed between the walls of the ducts 38 and 39 respectively.
  • Fig 5 shows a detail of a contraction 26 with bigger cross section areas 29, 29' on each sides and the connection of the evacuation air duct 39 to the exhaust air duct 38.
  • a piece of the evacuation duct 39 has been inserted and been furnished with an aperture 28 in the duct wall facing downstream.
  • Fine adjustment achieves with a turn 31 of the evacuation duct 39 in order to make the openings 28 take up different positions for correct suction effectiveness result.
  • Fig 6 shows a detail of the ending 22 of the evacuation air duct 39 in eligible inserted position 32 inside the evacuation duct attaining certain separate layers of air with different velocity, for adjustment of correct suction effectiveness result.
  • Fig 7 shows an additional detail of the evacuation air duct 39 ending 22, with slanted ending 33, in eligible inserted position 32 inside the evacuation duct attaining certain separate layers of air with different velocity, and in eligible turn 31, for adjustment of correct suction effectiveness result.
  • Fig 8 shows a further detail of how a contraction with insignificant air friction has been created by inserting of a spray nozzle shaped inset of sheet material 45 situated inside a T-duct 46.
  • the evacuation air duct 39 from the oven connects to the side opening duct.
  • the contraction part 26 of the nozzle shaped inset 45 has apertures 28 been made to allow oven exhaust air to flow around the nozzle shaped inset into the space 47 which has been formed between the wall of the exhaust air duct and the wall of the nozzle shaped inset and further on flow through the apertures 28 into the stove exhaust air duct 38.
  • Fig 1 shows how a stove kitchen fun over the stove can be used inside a kitchen 34 with an oven 35 situated on a different place than below the stove 36.

Abstract

La présente invention concerne un dispositif d'évacuation d'air dans un bâtiment, comprenant un conduit d'évacuation ou gaine d'échappement (38) qui s'étend depuis un premier point d'évacuation et qui comporte un ventilateur d'évacuation (37), et comprenant un deuxième conduit d'évacuation (39) qui s'étend depuis un deuxième point d'évacuation dans le bâtiment. La gaine d'échappement (38) présente une partie de section plus petite, ou rétrécissement (26), à l'intérieur de laquelle débouche le deuxième conduit de façon que la gaine d'échappement admet l'air évacué depuis le deuxième point d'évacuation grâce à une dépression créée par une vitesse augmentée appelée effet Venturi, qui est générée par le ventilateur de la gaine d'échappement (38).
