Definitions

  • the present invention relates to a ventilator for ventilation between a limited space and the outside air
  • the ventilator is of the type wherein the flow of outside air past the ventilator is used to convey air to and from the space, so that a circulation is obtained.
  • the problem which the present invention is intended to solve is therefore to provide a ventilator which is capable both of forcing air into a space and of sucking air out thereof, to bring about a circulation without using mechanical means but simply by means of the flow of outside air.
  • the requirement is that the ventilator should not need any readjustment after a change in wind direction, either manually or, for example, by the action of the wind.
  • the ventilator should fulfil its function substantially without movable parts.
  • Figures 1-3 show the basic principle of the present invention
  • Figure 4 is a perspective view of the ventilator according to the invention
  • Figure 5 is an axial section through the ventilator of figure 4 on the line V-V in Figure 6
  • Figure 6 is a cross-section through the ventilator on the line VI-VI in Figure 5
  • Figures 7 and 8 show a second and third form of embodiment respectively of the ventilator according to the invention
  • Figure 9 shows diagrammatically the use of the ventilator as a heat exchanger.
  • Figures 10 - 12 show diagrammatically a couple of examples of the installation of the ventilator according to the invention in boats and the path of the air flows with the heating unit respectively disconnected and connected up.
  • the basic principle of the ventilator according to the present invention is that a passage connection between the environment and the space intended for ventilation is divided up into a plurality of passage sections delimited from one another. These are adapted to maintain separate flows of incoming and outgoing air for communication between the outside air and the delimited space. As a result of the flow of the outside air past the ventilator, excess pressure develops in certain sections and low pressure in others.
  • the passage sections in which excess pressure develops in relation to the delimited space act as air intakes, while the passage sections in which low pressure prevails in relation to said space act as evacuation passages for air from the space to the outside air.
  • the invention is not a result of a simple dimensioning measure with a successive improvement of the ventilation characteristics in proportion to the number of passage sections.
  • the need for at least six sections can also be expressed so that the angle between two partitions which delimit the respective passage sections (a regular star shape is presupposed) should be so small that regardless of the direction of an external flow of air, at least two of the partitions belonging to any passage section facing the flow of air always have a substantially oblique inclination to the main direction of the flow of air.
  • the ventilator is mounted in a partition wall 1 between a delimited space 2 and the outside air.
  • the ventilator is mounted in an opening 3 in said partition wall so that a connecting passage 4 is formed by a ventilation drum 5 which comprises a flange 6 mounted with a sealing action against the outside of the partition wall.
  • the ventilator comprises a hood 7 which is closed in the upward direction and from which a plurality of partitions 8 extend downwards internally, extending in a plurality of planes extending through the centre axis of the ventilator, that is to say the longitudinal axis 9 of the connecting passage 4 and being directed radially outwards from said axis.
  • These partitions delimit a plurality of passage sections 10, eight in the example, into which said connecting passage is divided according to the invention.
  • the hood 7 is connected to the flange 6 by a number of outer and inner wall portions 11, 12 which serve as water breaks. Between these are provided outer openings 13 which are in communication with the associated passage sections 10.
  • the ventilation drum 5 comprises a collar 38 which serves as an obstacle to water.
  • the hood 7 and the openings 13 are also shown in Figure 4.
  • the partitions 8 extend through the connecting passage 4 and into said delimited space 2 and are crossed by a regulating disc 14 which comprises slits extending in the form of a star through which the partitions 8 extend and which are displaceable in hei ⁇ ht to regulate the flows of air.
  • 15 designates a cover which limits the movement of the regulating disc.
  • 17 designates a cover plate which is connected on the one hand to. the ventilation drum 4 and on the other hand to the partition wall 1, which may consist, for example, of a roof in a boat cabin, a caravan or a house.
  • the arrows 18 and 19 in Figure 5 indicate the path of the flow of air which is oppositely directed in two passage sections 10 situated opposite one another, in accordance with the principle of the invention.
  • What is important for the air circulation in the delimited space 2 is that the flows of air are directed sideways and substantially follow the inside of the partition wall 1, as a result of which a satisfactory circulation is obtained in the space as a result of the fact that the incoming air is conveyed along the partition wall, for example horizontally and then falls down, while the spent air in the space, which normally has a higher temperature than the incoming air, rises in the direction of the partition wall 1 and flows along this towards the ventilator from substantially the opposite direction in relation to the incoming stream of air and is evacuated in the direction of the arrows 19.
  • Figure 7 shows another form of embodiment of the ventilator which can be completely shut off by means of an upper valve disc 20, which forms a coherent unit with a lower valve disc 21 which is dished and comprises radially directed disc-shaped elements 22.
  • These form extension members of the partitions 23 which extend between the upper and the lower valve discs. 24 designates portions of the partitions which are rigidly connected to the hood 25. while the unit with the valve discs 20 and 21 and the partition portions 23 is displaceable in height between an open position, the upper position shown in the Figure, and a closed position in which the upper valve disc bears against the annular bearing surfaces 37 of the collar 26.
  • the unit which is displaceable in height can be fixed in position by means of a friction device, snap device or the like.
  • the displaceable unit may be so balanced that it automatically closes the ventilator if water flows in and collects in the dished lower valve disc 21 and causes the closing by the weight of the water.
  • the upper valve disc 20 is provided with recesses which cooperate with the portions 24 of the partitions, the edges 27 forming guides.
  • the alteration in height of the displaceable unit is brought about by means of a screw device which consists of a spindle 29 which can be turned by a knob 28 and which is in mesh, through a threaded portion 30 with the hood 31.
  • the upper valve disc 32 is guided in a corresponding manner to the form of embodiment shown in Figure 5. as a result of which turning of the unit which is displaceable in height and which consists of the upper valve disc 32, the partition portions 34 and a tubular portion 35 is avoided, while the lower valve disc 33 and the partition portions 36 are turned on turning of the screw device.
  • FIG 9 shows diagrammatically that the ventilator according to the invention can also be used as a heat exchanger and be equipped to advantage with a relatively long ventilation drum so that large contact surfaces are obtained between inflowing fresh air and evacuated room air.
  • the Figure only shows the connecting passage with the portions of the partitions situated in this.
  • the other parts of the ventilator can be made, for example, in accordance with the form of embodiment shown in Figure 5 but the embodiments shown in Figures 5 and 6 are also conceivable.
  • the direction of the inflowing fresh air is indicated by arrows which are designated by 38 while the direction of the outflowing room air is designated by arrows 39.
  • the arrows 40 and 41 indicate diagrammatically the main direction of flow of the fresh air and room air respectively in the heat exchanger.
  • FIGS 10 - 12 show examples of the installation of the ventilator 42 according to the invention in a motor boat 43 and a sailing boat 44.
  • the motor boat 43 comprises both a forward cabin and an after cabin 45, 46.
  • the ventilator works with the wind as a driving force in the manner described above, an exchange of air being obtained substantially in accordance with the arrows shown in Figure 8.
  • a boat is provided with a heating unit 47, 48 with a fan connected in, warm air is introduced into the cabins via warm-air ducts 49, 50, 51 and excess pressure is obtained in the cabins.
  • the ventilator automatically reduces the supply of fresh air but evacuates spent room air in proportion to the warm air supplied.
  • the ventilator When the heating unit is not in operation, the ventilator again works automatically with the wind as a driving force.
  • a boat equipped with a heating unit pan thus be made with ventilation ducts in the conventional manner.
  • the passage sections can be formed otherwise than as shown, for example in the form of a tube for each section which comprises opening ends directed sideways.

Abstract

Ventilateur destine a la ventilation entre un espace delimite et l'air exterieur. Un passage de connexion (4) s'etendant au travers du ventilateur est divise en une pluralite de sections de passage (10) qui sont delimitees les unes par rapport aux autres a l'aide d'au moins une portion de parois externes (7/20/32) et des cloisons (8) qui sont dirigees symetriquement et de meme longueur s'etendant exterieurement a partir de l'axe longitudinal central (9) du passage de connexion (4). Les sections sont adaptees pour maintenir une communication entre l'air exterieur et l'espace, et comprennent a leurs extremites externes, face a l'air exterieur, une ouverture externe (13) et, a leur extremite interne, face a l'espace, une ouverture interne. Les ouvertures externes sont dirigees de cote par rapport a l'axe longitudinal (9) du passage de connexion (4), de sorte que les ouvertures soient distribuees sur la peripherie du ventilateur. L'angle entre deux cloisons adjacentes (8) est assez petit pour que, independamment du sens du courant d'air exterieur, au moins deux des cloisons (8) sensiblement transversales a l'axe longitudinal (9) et appartenant a l'une des sections de passage en regard du courant d'air soient toujours sensiblement obliques par rapport a la direction principale du courant d'air. En consequence, avec chaque direction du vent, au moins une entree en forme d'entonnoir est dirigee dans le sens du vent.
