Definitions

  • This invention relates to an improved ventilation grid, more particularly a ventilation grid for installation in windows, doors and such, which substantially consists of a housing in which a ventilation duct is situated which defines an inlet opening and an outlet opening, whereby the ventilation duct can be closed off by means of a rotatable closing element on which one or more closing parts are provided.
  • a ventilation grid of the aforementioned type such as known from EP-A-0 021 164 the closing parts are made in a straight manner, such that between the two closing parts, a duct with straight, parallel walls is formed.
  • Such aforementioned ventilation duct in fact consists of different parts, amongst which one part which is formed by the aforementioned closing parts, which parts are connected to each other at certain angles, whereby, moreover, a lot of irregularities may prevail in the ventilation duct and in the inlet opening, such as protrusions, sudden changes in flow direction and similar on the applied profiles.
  • a first disadvantage of these known ventilation ducts is that the air flow in the ventilation duct meets a large resistance, as this duct does not have smooth walls.
  • a second disadvantage of the aforementioned known ventilation ducts is that, as a result of the angles and the irregularities comprised in the duct, a lot of air turbulences arise in said ventilation duct, which then again results in an increasing resistance for the air flow.
  • a third known disadvantage consists in that the flow sounds in the ventilation duct can be increased up to a level which is experienced as impairing by certain persons, which increase also is a result of the air turbulences and of the resistance undergone by the air flow in the ventilation duct.
  • the distance between the two curved closing parts is variable throughout the length of formed duct, which leads to irregularities in the airflow through said duct and which is also a source of undesirable noise.
  • the airflow in the ventilation duct meets a large resistance, as the duct shows several sudden changes in flow direction in the duct as well as in the inlet and outlet openings and also comprises protruding parts in the airflow, resulting in only a limited airflow through the ventilation grid, and hence resulting in poor ventilation.
  • the present invention aims at an improved ventilation grid which provides in a better flow through the ventilation duct, as a result of which the aforementioned and other disadvantages are excluded.
  • the invention relates to an improved ventilation grid of the type substantially consisting of a housing in which a ventilation duct is situated which defines an inlet opening and an outlet opening, whereby the ventilation duct can be closed off by means of a rotatable closing element substantially consisting of two closing parts installed diametrically opposite each other, in between which a duct is situated, characterized in that at least one of the aforementioned closing parts of the closing element is made curved.
  • the closing element of an improved ventilation grid according to the invention is formed by two closing parts situated diametrically opposite each other which each have a curved wall or which, in other words, are made shell-shaped.
  • the walls of the closing parts are situated on two concentric circles to which the duct walls in front of and behind the closing element may connect.
  • a ventilation grid according to the invention substantially consists of a housing 1 in which a slot-shaped ventilation duct 2 is provided which defines an inlet opening 3 and an outlet opening 4 in the housing 1.
  • the housing 1 At the height of the inlet opening 3, the housing 1 has an outward-bent lip 5.
  • a closing element 6 is provided which substantially consists of two shell-shaped closing parts 7-8, in between which a duct 9 is situated.
  • the closing parts 7-8 are connected to each other at their extremities by means of two end pieces 10 which, by means of pivot pins 11, are beared in the end pieces of the housing 1.
  • one or more spacing elements 12 installed in slots 13-14 may be provided between the closing parts 7-8.
  • spacing elements 12 provide in a reinforcement of the closing element 6, which certainly is necessary for long ventilation ducts 2.
  • the aforementioned shell-shaped closing parts 7-8 have curved walls 15-16, namely, a convex wall 15 and a concave wall 16, in such a manner that the walls 15-16 follow the curvature of the ventilation duct 2, such that the resistance for the air flow diminishes.
  • the closing parts 7-8 each are provided at their edges 17-18, 19-20 respectively, with sealing elements 21 known in themselves, for example, in the form of brushes or such, which can cooperate with parts 22 of the ventilation duct 2.
  • the ventilation duct 2 can be provided with a valve 23 at its inlet opening 3, which valve itself is movable and which, under the influence of pressure differences or wind load on the ventilation grid, enlarges or diminishes said inlet opening.
  • the ventilation grid according to this preferred form of embodiment is provided with a grid 26 at its outlet opening 4, which grid is clicked onto the housing 1 and which prevents that the ventilation duct 2 is visible from the room where it is ending and which, at the same time, serves as a protection against insects.
  • the closing element 6 When the ventilation grid is closed, as represented in figure 1, the closing element 6 is turned in such a manner that the closing parts 7-8 close off the ventilation duct 2 hermetically, in that the sealing elements 21 are pressed against the aforementioned parts 22 of the ventilation duct 2.
  • the ventilation duct 2 is turned open until it comes into the position as represented in figure 2.
  • the closing element 6 is held, amongst others, in the closed position and in the completely opened position, in its place by the friction between the sealing elements 21 and the parts 22 of the ventilation duct 2.
  • the air resistance in the ventilation duct 2 is strongly reduced, in particular at the height of the closing element 6, which in its turn has as a consequence that considerably less air turbulences occur in the ventilation duct 2, with a better air flow and less flow sounds as a result.
  • the ventilation duct 2 moreover is provided with acoustically insulating material 27-28, more particularly in the zone in front of and the zone behind closing element 9.
  • the insulating material 27-28 is formed in such a manner that the streamline of the ventilation duct 2 is improved in that the angles of the ventilation duct 2 are rounded and the irregularities of the duct 2 are covered by this acoustically insulating material.
  • the closing parts 7-8 of the closing element 6 can be situated in the same plane as the plane of the walls 29-30 of the acoustically insulating material 27-28 in the ventilation duct 2, as a result of which a better air flow is obtained, whereas the acoustically insulating material 27-28 moreover provides for a further reduction of the flow sounds.
  • acoustically insulating material might be provided in the slots 13-14 of the closing parts, between the spacing elements 12, such that the walls 15-16 will cause even less air turbulences.
