Abstract

An acoustic air ventilator (10) comprises a substantially box shaped structure having a top plate (32) and base plate (26) and four walls disposed there between and an elongate duct (38) arranged between an inlet port (56) and an exit port (60), the duct defining a flow path for air, wherein the ventilator is positioned, in use, adjacent to a window frame (12) within a building and the inlet port is provided in the base plate of the ventilator.

Description

* 2446224 Acoustic Ventilator Apparatus The present invention relates
to acoustic ventilation apparatus and more particularly but not exclusively to an acoustic ventilator for buildings.
it is known and desirable to provide ventilators within buildings which allow the ingress of fresh air into the building.
However ventilators may necessarily be left open which allows external noise to pass there through and it is particularly prevalent in road facing buildings.
Acoustic ventilators attempt to alleviate this problem but known examples can be unsightly and involve complicated internal features. One example of an acoustic ventilator is disclosed in prior patent GB2398377. However this particular ventilator comprises a complex inner structure of a plurality of tubes disposed to direct high frequency noise towards an acoustic damping material. The tube structure also necessitates the ventilator to be of a fairly thick size thus restricting its aesthetic qualities and the range of locations it can be employed within a building.
There is a need therefore for an acoustic ventilator which aims to address at least one disadvantage of known building acoustic ventilators whether discussed herein or otherwise.
According to the present invention there is provided an acoustic air ventilator comprising a substantially box shaped structure having a top plate and base plate and four walls disposed therebetween and an elongate air duct arranged between an inlet port and an exit port, said duct defining a flow path for air wherein said ventilator is positioned, in use, adjacent to a window frame within a building and said inlet port is provided in the base plate of ventilator.
Advantageously the ventilator inlet port is hidden from view when in situ.
Preferably the ventilator is positioned over a window within a building.
Preferably the ventilator inlet port is a slot provided in the base plate of the ventilator.
Preferably the ventilator is an elongate box shaped structure.
Preferably the inlet port is provided at one end of the base plate of the box shaped ventilator and the outlet port is provided at the other end of the base plate.
Preferably the elongate duct is a substantially u-shaped channel.
Preferably the ventilator is positioned between a window lintel and the top of a window frame. -3 -
Preferably the ventilator comprises first and second tray elements, and first and second u-shaped end cover plates, the first tray element comprising a base plate and two upstanding end walls and the second tray being positioned in an upside-down manner over the first tray, said second tray also comprising a flat base plate and two upstanding end walls.
Preferably the upper tray is positioned in an upside-down manner such that it is positioned over the lower tray.
Preferably the first end cover plate partially overlaps the base plates of the first and second trays.
Preferably the first end cover plate comprises an opening in the form of an air inlet port.
Preferably the inlet port is provided in the underside part of the u-shaped end cover plate.
Preferably the air outlet port is provided in the underside of the second end cover plate.
Preferably the inlet port is an elongate slot.
Preferably the outlet port is an elongate slot. -4
Preferably the filler material is foam.
Preferably the filler material is rock wool.
Preferably the first end cover plate is fixed to the base plate of the first and second trays by plastic rivet fixings.
Preferably a foam material is provided between the first end cover plate and the base plate of the first and second trays.
An embodiment of the present invention in which: Figure 1 is a side cross section of a ventilator in situ.
Figure 2 is a side cross section of a ventilator in accordance with an embodiment of the present invention, Figure 3 is a perspective view of the underside of a ventilator according to an embodiment of the present invention.
Figure 4 is a perspective view of the ventilator according to an embodiment of the present invention.
Figures 1 to 4 illustrate a first embodiment of a ventilator apparatus 10 which comprises a substantial box-like structure situated between a window frame -5 12 and the brickwork of a building 14. Internally within the building the box shaped ventilator apparatus 10 fits within the plasterboard window recess 16 and the plasterboard internal wall 18 and the building block work 20.
Advantageously the slim box like ventilation apparatus 10 is designed to fit snugly within the building elements such that no obtrusive external ventilator structure is seen.
The ventilation apparatus 10 comprises a lower tray 22 and an upper tray 24.
The lower tray 22 compnses a base plate 26 disposed between two upstanding walls 28 and 30. The upstanding wall element 28 is of a larger depth than its opposing wall element 30. This ensures that the flow of air through the air duct is efficient but also provides an optimum level of sound absorption by ventilator.
The second tray 24 also comprises a base plate 32 disposed between two walls 34 and 36. Each tray is filled to its deepest point with acoustic foam or other suitable sound absorbent material such as rock wool. The second tray 24 is positioned over the first tray 22 and spaced apart to provide an elongate air path 38 there between. The upper tray 24 is of a longer length than the lower tray 22 such that in situ the upper tray 24 extends beyond the end of end 40 of the lower tray 22. This provides a chamber 42 at the internally positioned at the end of the ventilator 10.
End cover plates 44 and 46 are provided over the opposing walls 28, 34, 30 and 36. Each end plate 44 and 46 is essentially a box lid shaped structure manufactured from steel or aluminium. The cover plate 44 comprises and end base plate 48 and two opposing walls extending there from, this cover plate 44 is partially positioned over the end walls 28 and 34 of the trays 22 and 24 such that a gap is provided between the base plate 48 of the end cover plate 44 and the watls 34 and 28. This allows a chamber to be provided between the ends 28 and 34 of the trays 22 and 24. The end cover plate 44 is affixed to the trays 22 and 24 via plastic rivets 50 seen more clearly when referring to Figures 3 and 4.
The first cover plate 44 comprises a slot 56 in its underside wall 58 to allow the ingress of air into the chamber 54. Advantageously the slot is hidden from view once the ventilator 10 is in situ within the building.
The second end cover plate 46 abuts against the end wall 36 of the upper plate 24 but does not abut against the upstanding wall 30 of the lower tray 22 thus forming an air chamber 42. A slot 60 is provided in the underside wall 62 of the end cover plate 46 which allows the egress of air from the chamber into the building. This is provided by a slot or grill 64 being provided in the plasterboard 16.
Acoustic absorbent foam material 66 is provided as filler between the first end cover plate 48 and the upper and lower trays 22 and 24. This advantageously ----7 attenuates the noise from the end cover plate through the trays and then into the building.
The end wall 70 of the first cover plate 48 sits flush with the external brickwork face 72 thus providing an attractive finish. The ventilator slot 56 is hidden from view and therefore also provides an attractive finish to the exterior of the building.
Internally, again the exit slot 60 is hidden from view behind plasterboard thus allowing the slot or grill 64 within the internal plasterboard to be of an aesthetically pleasing design and not one dictated by the design constraints of the ventilator.
The elongate slot and internal arrangements of the trays and end cover plates provides an essentially u-shaped air channel which incorporate changes in direction of the air essential for high noise reduction and draft prevention and providing an attenuator with good sound reducing properties. The elongate air channel 38 also advantageously provides maximum air transfer which is both simple and easy to install.
