Definitions
- the invention relates to a ventilator, adapted to be mounted in a window or door, and comprising a housing provided with an air inlet window situated at the outer side of said housing, and, in particular, being shielded against rain, and with an air outflow window situated at the inner side of said housing, which air inlet window comprises a downwardly directed passage in the outer housing portion, and in which air passage a hinged vane with a horizontal hinge axis is arranged, which vane is adapted to move between a first lower and substantially horizontal position, and an upper inclined position, both positions being determined by a stop, the wall of said passage cooperating with the edge of said vane which is opposed to the hinge axis being curved in such a manner that said wall is situated at a distance from said vane edge when the vane is in its first preferred position.
- Such a ventilator is known from the Australian patent 19.729/67 which patent describes a ventilator with a vane inside the housing, which vane can be in the open or closed position. With a ventilator according to this Australian patent the vane will be in the closed position when the air current through the housing will be above a certain value. Such a vane will return to the open position when the air current is underneath a certain value which is lower than the air current above which the vane will return to the closed position.
- the French patent 2.087.198 describes also a ventilator with a certain number of independent vanes placed beside each other, each vane consisting of a flexible or elastic sheet, which will be moved to the closed position due to air current. The same as what happened to the vane with the Australian ventilator happend with the French ventilator. In both cases the vane can only be in an open position or a closed position and not in between.
- the aim of the invention is to provide a ventilator with which it is possible to adapt the air flow through the ventilator such that within a certain range of changing of the wind intensities, the air flow will substantially stay constant.
- the ventilator is characterised in that when said vane is moving towards the upper position, said passage will be gradually reduced and in the closed position of said vane, leak openings in said vane provide a given minimum or smallest air flow passage, so as to maintain a residual air passage.
- said leak openings are formed by notches in the free edge of said vane.
- the ventilator is also provided with a second vane, which can be operated from the outside and which can be put into an open or a closed position. This makes it possible to close the ventilator in case the wind becomes to strong, that even in the closed position of the vane with the leak openings the air current is to great.
- the ventilator shown is intended to be fixed in a frame 1 having a rebate 2 by means of a glass lath 3, and bears, on the other side, on a glass pane 4 with an intermediate sealing rim 5.
- the invention is, however, not restricted to this embodiment.
- the ventilator according to the invention comprises a housing 6 having, at its outer side, an inlet window 7, and, at its inner side, an outlet window 8.
- the inlet window 7 is downwardly directed, so that raining in is prevented, and, moreover, a favourable flow in the case of wind gusts is obtained.
- a vane 9 is provided, which is hingedly connected, at one side 10, with the housing 6, the lower position thereof being defined by an inner ledge 11 of the housing 6. In this lower position, in which the vane 9 is substantially horizontally directed, the free edge 12 of said vane is at some distance from a curved wall 13 of the housing 6, so that a flow passage 14 remains free.
- the vane 9 is preferably provided with openings 23 which, in the closed position, provide a given airflow passage, so as to counteract fluttering of said vane around the closed position.
- These openings 23 can be made in the form of notches in the edge 12.
- a second hinged vane 16 with a horizontal hinge axis 17 is provided, which vane can be moved and fixed by means of an actuating handle not shown.
- the housing 6 possesses in front of the free edge 18 of said vane a curved wall portion 19, the curvature of which deviating from the path described by the edge 18 in such a manner that a gradual change of the airflow passage will be obtained.
- a distribution hood 20 is provided over the outlet window 8, said hood being provided with holes or slots 21 by means of which a good mixing effect can be obtained.
- the second hinged vane 16 can be made of plastics, and form a unitary structure with the insulation bridges 22 between the front and the rear housing portions.

Description
- The invention relates to a ventilator, adapted to be mounted in a window or door, and comprising a housing provided with an air inlet window situated at the outer side of said housing, and, in particular, being shielded against rain, and with an air outflow window situated at the inner side of said housing, which air inlet window comprises a downwardly directed passage in the outer housing portion, and in which air passage a hinged vane with a horizontal hinge axis is arranged, which vane is adapted to move between a first lower and substantially horizontal position, and an upper inclined position, both positions being determined by a stop, the wall of said passage cooperating with the edge of said vane which is opposed to the hinge axis being curved in such a manner that said wall is situated at a distance from said vane edge when the vane is in its first preferred position.
- Such a ventilator is known from the Australian patent 19.729/67 which patent describes a ventilator with a vane inside the housing, which vane can be in the open or closed position. With a ventilator according to this Australian patent the vane will be in the closed position when the air current through the housing will be above a certain value. Such a vane will return to the open position when the air current is underneath a certain value which is lower than the air current above which the vane will return to the closed position.
- The French patent 2.087.198 describes also a ventilator with a certain number of independent vanes placed beside each other, each vane consisting of a flexible or elastic sheet, which will be moved to the closed position due to air current. The same as what happened to the vane with the Australian ventilator happend with the French ventilator. In both cases the vane can only be in an open position or a closed position and not in between.
- The aim of the invention is to provide a ventilator with which it is possible to adapt the air flow through the ventilator such that within a certain range of changing of the wind intensities, the air flow will substantially stay constant.
- According to the invention the ventilator is characterised in that when said vane is moving towards the upper position, said passage will be gradually reduced and in the closed position of said vane, leak openings in said vane provide a given minimum or smallest air flow passage, so as to maintain a residual air passage.
- Under normal circumstances with little wind said vane is in its lower, prefered position, in which the air passage is sufficient for ventilation. When the wind increases, said vane is lifted, and the passage will be narrowed so that the airflow rate will not substantially change. In the closed position of the vane there will still remain a minimum or smallest possible air flow.
- Preferably said leak openings are formed by notches in the free edge of said vane. Preferably the ventilator is also provided with a second vane, which can be operated from the outside and which can be put into an open or a closed position. This makes it possible to close the ventilator in case the wind becomes to strong, that even in the closed position of the vane with the leak openings the air current is to great.
- The invention will be elucidated below in more detail by reference to a drawing, showing a diagrammatic cross-section of a ventilator according to the invention.
- The ventilator shown is intended to be fixed in a frame 1 having a
rebate 2 by means of aglass lath 3, and bears, on the other side, on a glass pane 4 with anintermediate sealing rim 5. The invention is, however, not restricted to this embodiment. - The ventilator according to the invention comprises a
housing 6 having, at its outer side, aninlet window 7, and, at its inner side, anoutlet window 8. Theinlet window 7 is downwardly directed, so that raining in is prevented, and, moreover, a favourable flow in the case of wind gusts is obtained. - In the inlet portion of the housing 6 a
vane 9 is provided, which is hingedly connected, at oneside 10, with thehousing 6, the lower position thereof being defined by aninner ledge 11 of thehousing 6. In this lower position, in which thevane 9 is substantially horizontally directed, thefree edge 12 of said vane is at some distance from acurved wall 13 of thehousing 6, so that aflow passage 14 remains free. - In the upper position of the
vane 9, which is, for instance, defined by a stop at theterminal edge 15 of thewall 13, saidpassage 14 is substantially closed. The curvature of thewall 13 deviates in such a manner from the path of thevane edge 12 that thepassage 14, when said vane is moving, will gradually change. - The
vane 9 is preferably provided withopenings 23 which, in the closed position, provide a given airflow passage, so as to counteract fluttering of said vane around the closed position. Theseopenings 23 can be made in the form of notches in theedge 12. - It has appeared that with such a vane, even in the case of wind gusts, a substantially uniform airflow through the ventilator can be obtained.
- In order to close the air passage or to allow controlling the airflow therethrough, in the outlet window 8 a second hinged
vane 16 with ahorizontal hinge axis 17 is provided, which vane can be moved and fixed by means of an actuating handle not shown. Thehousing 6 possesses in front of thefree edge 18 of said vane acurved wall portion 19, the curvature of which deviating from the path described by theedge 18 in such a manner that a gradual change of the airflow passage will be obtained. - In order to uniformly distribute the inflowing air, preferably a
distribution hood 20 is provided over theoutlet window 8, said hood being provided with holes orslots 21 by means of which a good mixing effect can be obtained. - In particular the second hinged
vane 16 can be made of plastics, and form a unitary structure with theinsulation bridges 22 between the front and the rear housing portions.
