Definitions

the present invention relates to a ventilation device comprising an air flow passage for allowing air to flow through said air flow passage from an inlet to an outlet and a self-regulating valve which is arranged in the air flow passage so as to be tiltable about a tilting point in order to regulate an air flow opening in the air flow passage, in such a way that, at negative pressure at the outlet with respect to the inlet at an increasing pressure difference between the inlet and the outlet, said self-regulating valve moves in a first direction of rotation in order to restrict the air flow opening and, at positive pressure at the outlet with respect to the inlet at an increasing pressure difference, moves in a second direction of rotation, opposite to the first direction of rotation, in order to restrict the air flow opening.
the present invention relates to a method for converting an existing ventilation device to a ventilation device according to the present invention.
the pressure differences across building components are continuously subject to changes due to variations in temperatures, wind speeds and directions, as well as the use of the building (opening doors and windows, use of ventilation devices). With conventional ventilation devices, this results in a continuous change in the air flow rate.
An increasing number of ventilation devices are provided with an automatic adjustment of the air flow opening (cross section of the passage) and consequently also of the air flow rate, based on the pressure difference across the ventilation grille (the ventilation device).
Such ventilation devices are known, inter alia, from NL 1 025 600 C2 , EP 0 606 945 A1 , NL 1 014 499 C , EP 2 051 020 A1 , EP 0 362 913 A1 , EP 0 503 722 A1 , NL 9 102 132 A , DE 35 28 527 A1 etc. and are usually described as being self-regulating.
such self-regulating ventilation grilles may be provided with a self-regulating valve which automatically changes the cross section of the passage or the air flow opening of a ventilation device when the pressure difference across the ventilation device changes.
the present invention relates to such ventilation devices which operate without an actuator or motor (with an autonomous self-regulating valve).
Such ventilation devices are typically provided for supplying outdoor air to an interior space of a building. In this case, it is usually undesirable for hotter indoor air from the interior space of the building to flow outside via this ventilation device.
DE 35 28 527 A1 describes such a ventilation device with a self-regulating valve which restricts the air flow opening at positive pressure at the outlet with respect to the inlet at increasing pressure difference across the valve and, at a certain pressure difference, even closes it off completely, thus preventing air from flowing through the ventilation grille in the opposite direction.
this self-regulating valve to too great an extent prevents the supply of air through this ventilation device, so that such a ventilation device cannot be designed to be compact.
a ventilation device comprising an air flow passage for allowing air to flow through said air flow passage from an inlet to an outlet and a self-regulating valve which is arranged in the air flow passage so as to be tiltable about a tilting point in order to regulate an air flow opening in the air flow passage, in such a way that, at negative pressure at the outlet with respect to the inlet at an increasing pressure difference between the inlet and the outlet, said self-regulating valve moves in a first direction of rotation in order to restrict the air flow opening and, at positive pressure at the outlet with respect to the inlet at an increasing pressure difference, moves in a second direction of rotation, opposite to the first direction of rotation, in order to restrict the air flow opening, in which the self-regulating valve comprises a control limb which, viewed from the inlet to the outlet, is arranged upstream of the tilting point and comprises a return limb which, viewed from the inlet to the outlet, is substantially arranged downstream of the tilting point, at an angle with respect to the control limb, in
the self-regulating valve hinders the air flow only to a minimal extent during normal operation and this self-regulating valve moves much more evenly.
the expression "arranged at an angle with respect to each other” should be interpreted broadly, in the sense that these limbs are not arranged completely in line with each other.
the limbs themselves may in this case have all kinds of shapes and may also be arranged partially in line with each other, if desired. Preferably, however, these limbs are also at an angle with respect to each other in a narrower sense.
the term "impingeable" indicates that the air flow can act on the respective limb, in such a way that a movement of the self-regulating valve is initiated thereby.
the self-regulating valve is arranged in the air flow passage in such a way that, at negative pressure at the outlet with respect to the inlet at increasing pressure difference, the forces acting on the return limb will initially outweigh any forces which may act on the control limb and eventually the forces acting on the control limb outweigh any forces which may act on the return limb.
the valve may in this case be arranged in such a way that, at negative pressure at the outlet with respect to the inlet at increasing pressure difference, an air flow initially flows onto the return limb, then onto both the control limb and the return limb and subsequently only flows onto the control limb.
the self-regulating valve is preferably arranged in the air flow passage in such a way that, at positive pressure at the outlet with respect to the inlet at a certain pressure difference, the air flow opening is closed off by means of the return limb.
control limb and the return limb are the only limbs of the self-regulating valve of a ventilation device according to the present invention which are impingeable by the air flow.
control limb and the return limb are configured in such a way that the rotary movement in the first direction of rotation at increasing pressure difference is slower than the rotary movement in the second direction of rotation at increasing pressure difference.
the self-regulating valve is configured such that, when there is no pressure difference between the inlet and the outlet, the return limb partially closes off the through-flow opening.
the self-regulating valve is placed on one or more supporting bodies in order to arrange it in the air flow passage.
placing the valve on a supporting body in this way results in a line contact between the valve and this supporting body which forms said tilting point.
this line contact may move, in which case said tilting point will also move.
the self-regulating valve comprises a hook element
the ventilation device comprises a corresponding hook element which is arranged in the air flow passage, onto which the hook element of the self-regulating valve is hooked in order to arrange the self-regulating valve in the air flow passage.
this supporting body is configured as said hook element.
the tilting point is arranged at the top of the air flow passage, so that the self-regulating valve is arranged substantially at the top of the air flow passage.
the self-regulating valve of a ventilation device according to the present invention is arranged closer to the inlet of the air flow passage than to the outlet.
the control limb of a ventilation device according to the present invention preferably extends substantially between the tilting point and the inlet.
the return limb preferably extends between the tilting point and the outlet.
the object of the present invention is also achieved by providing a method for converting a ventilation device, comprising an air flow passage for allowing air to flow through said air flow passage from an inlet to an outlet, in which a self-regulating valve is arranged in the air flow passage in such a way that an above-described embodiment of a ventilation device according to the present invention is obtained.
this method may be provided for converting a ventilation device comprising a self-regulating valve which is arranged in the air flow passage so as to be tiltable about a tilting point to regulate an air flow opening in the air flow passage, in which the fitted self-regulating valve is then preferably replaced by a self-regulating valve by means of which an above-described embodiment of a ventilation device according to the present invention is obtained.
the illustrated ventilation devices (1) are typically ventilation grilles (1) which are intended to be incorporated or installed at the top of a window in order to make air flow through a wall in which this window is incorporated possible.
These ventilation devices (1) comprise several part profiled sections which are assembled to form, on the one hand, a top profiled section (12) and, on the other hand, a bottom profiled section (13).
the various part profiled sections may be made, for example, from plastic or aluminium, for example by means of extrusion. Together with head plates which are attached to the ends of these profiled sections (12, 13), these profiled sections (12, 13) form an elongated, substantially beam-shaped housing for the ventilation grilles (1).
An air flow passage (2) extends between the top profiled section (12) and the bottom profiled section (13) through which air from an inlet (3), which is typically arranged in an exterior space, can flow to an outlet (4), which is typically arranged in an interior space.
a self-regulating valve (5) is suspended in the air flow passage (2) so as to be tiltable about a tilting point (6).
a hook-shaped profiled-section part (9) is provided in the top profiled section (12) in the illustrated ventilation devices (1).
the self-regulating valve (5) is in turn provided with a hook-shaped part (10) by means of which this valve (5) is hooked onto the top profiled section (12) via the hook-shaped profiled-section part (9) in order to suspend this valve (5) in the air flow passage (2).
the self-regulating valve (5) may, for example, be made of plastic by means of extrusion.
the self-regulating valve (5) of the ventilation device (1) comprises a control limb (7) which extends substantially on a first side of the tilting point (6) and a return limb (8) which extends substantially on a second side of the tilting point (6), viewed in the direction of air flow.
This control limb (7) and this return limb (8) are substantially arranged according to the direction of air flow and are both impingeable.
the counterweight (11) of the self-regulating valve (5) does not extend substantially according to the direction of air flow and is not impingeable, as the air flow cannot act thereon in such a manner here that this would initiate a movement of the self-regulating valve (5).
the air flow in this case initially only has an impact on the inner part of the self-regulating valve (5), in which case the air flow flows only onto the return limb (8), as can be seen in Fig. 4 . Only after a specific angular displacement does the air flow also have an impact on the outer part of the self-regulating valve (5), in which case the air flow also flows onto the control limb (7), as can be seen in Fig. 5 . Subsequently, the impact on the inner part of the self-regulating valve (5) gradually diminishes and the air flow only flows onto the control limb (7), as can be seen in Fig. 6 . In this way, the movement of the self-regulating valve (5) is more even compared to the existing self-regulating valve (5).
the air flow causes the self-regulating valve (5) to move in the opposite direction of rotation (S).
the prior-art self-regulating valve (5) in this case returns to its starting position, as can be seen in Fig. 3 .
the self-regulating valve (5) according to the invention initially also returns to its starting position ( Fig. 4 ), following which the air flow has a great impact on the outer part of the valve (5), with air flow only flowing onto the return limb (8), as can be seen in Fig. 8 , until this return limb (8) closes off the air flow opening, as can be seen in Fig. 9 , and air discharge via the ventilation grille (1) is prevented.
the self-regulating valve (5) according to the invention has the additional advantage that so-called flapping of this valve (5), i.e. caused by the valve (5) hitting against the top profiled section (12), is prevented.
the valve (5) will want to tilt back when the pressure difference decreases.
the prior-art valve (5) tilts so quickly in this case that it will start to flap.
the valve (5) according to the invention after only a slight rotation, the inner part of the valve (5) is again subjected to the impact of the rest of the air flow through the air flow passage (2), as can be seen in Fig. 7 , as a result of which the movement of the valve (5) is slowed down and the risk of flapping is significantly reduced.
