EXHAUST AIR BLOW-OUT DEVICE
FIELD OF THE INVENTION
20185111 prh 08 -02- 2018
The present invention relates to an exhaust air blow5 out device adapted for mounting to the outer wall of a building.
BACKGROUND OF THE INVENTION
In prior art is known an exhaust air blow-out device. 10 The exhaust air blow-out device comprises a connector collar. The connector collar has a circular crosssection and an inner surface having an inner first diameter. The connector collar is connectable to an exhaust air channel of a mechanical house ventilation 15 system to form a part of the exhaust air channel. A throttling device is arranged inside the connector collar for increasing blow-out rate of the exhaust air. The current building regulations require that the blow-out rate should be at least 5 m/s so that the ex20 haust air does not mix with the fresh intake air, the intake opening being often located near to the exhaust air blow-out device. However, exhaust air rate coming via the exhaust air channel from the mechanical house ventilation system to the blow-out device may be less 25 than the required 5 m/s. Therefore, a throttling device is needed to increase the blow-out rate of the exhaust air. The problem with the prior art exhaust air blow-out devices is that the throttling rate of the throttling device is fixed and not variable de30 pending on the prevailing exhaust air rate coming from the mechanical house ventilation system. A further problem is that the throttling device causes noise.

The exhaust air blow-out device comprises a connector collar. The connector collar has a circular cross-section and an inner surface having an inner first diameter. The connector collar is connectable to an exhaust air channel 20 of a mechanical house ventilation system to form a part of the exhaust air channel. The exhaust air blowout device comprises a throttling device. The throttling device is arranged inside the connector collar for increasing blow-out rate of the exhaust air. Ac25 cording to the invention the throttling device comprises a nose cone element having an outer contour with aerodynamic shape of a nose cone. The nose cone element is arranged concentrically inside the connector collar. The nose cone element comprises a tip di30 rected towards the exhaust air flow and a circular trailing edge having a second diameter smaller than the first diameter defining a circular blow-out gap between the inner surface of the connector collar and the trailing edge of the nose cone element the exhaust 35 air being blown out via said circular gap forming a throttling means the second diameter defining the throttling rate. The nose cone element comprises a tip
20185111 prh 08 -02- 2018 section and a set of adjusting sections connectable successively with the tip section to form an assembly forming the nose cone element having a desired second diameter of the trailing edge. Each of the adjusting 5 sections have an outer contour being a part of said nose cone shape and gradually increasing second diameters of the trailing edges, so that the number of adjusting sections can be varied for adjusting the exhaust air blow-out rate by adjusting the face area of 10 the blow-out gap.
The advantage of the invention is that due to the aerodynamic nose cone shape the throttling device has a small resistance of flow while being able to increase 15 the blow-out rate of the exhaust air. Further, the aerodynamic nose cone shape reduces noise of the blowout exhaust air flow.
