The air discharge aperture is arranged at an upper part of the box column and is provided with an at least partially closable screen (4) (shown as an adjustable louvered screen). The air fan (2) with the driving motor (3) is arranged at a lower part of said box column to communicate with an aperture (8) in the exterior wall. A pipe member (9) is arranged to line the aperture (8) and is provided with an entry grille (10). As shown there are dust filters 6' (which may be a sound damper), 16 (eg for sterilising) and 6. The apparatus may also include heater elements and humidifying means (not shown). <IMAGE>

Description

SPECIFICATION Ventilating apparatus for sealed spaces TECHNICAL FIELD OF THE INVENTION This invention relates to apparatus for ventilating sealed spaces, which are used for domestic occupation, for example, extraction fans which are provided with a driving motor and are installed in a wall box set into an outside wall of a room. These extraction fans convey the spent air of the room to the outside of the building, by which operation the pressure of the air inside the room is reduced. In consequence of this fresh air from the surroundings will flow into the room, this replacement air is then uncontrolled and unpurified. A further disadvantage is that an aperture must be knocked out of the outer wall of the building to allow fitting of the wall box.
BACKGROUND ART In some known sound proofed double glazed windows of sealed rooms, which in the usual way are not open for ventilation, there is installed both above and below the window frame a box shaped air lock provided with sound damping material, see for example, German Patent Specification DE-AS 19 31 346. In such cases one of the air locks contains an air supply fan provided with a driving motor, whilst the other air lock serves for removing the air from the room. The vertical height demanded by these air locks makes it necessary to reduce the possible effective surface area of the window. Furthermore, if the air locks are subsequently installed, large wall apertures have to be broken away.
An object of the present invention is to provide a ventilating apparatus, which will satisfy the requirements for sealed spaces, and which can be installed in a simple manner, and will avoid the necessity for making large apertures in the walls.
DISCLOSURE OF THE INVENTION According to the present invention ventilating apparatus for sealed spaces comprises an air lock, the interior of which is at least partly lined with sound damping material, the air lock having an opening in which there is arranged a motor driven air fan and also having a screened air discharge aperture, the air lock being designed as a box column arranged to be mounted on the floor of the sealed space and either supported against or at a relatively small distance from an exterior wall of the space, the air discharge aperture being arranged at an upper part of the box column and being provided with an at least partially closable screen, and the air fan with the driving motor being arranged at a lower p3rt of said box column to communicate with an aperture in the exterior wall.
Preferably the ventilating apparatus has a pipe member arranged to line the aperture and provided with an entry grille.
The ventilating apparatus may also have dust filter elements removably arranged in the air lock and extending over the cross-section of the air lock.
A dust filter may be arranged in a pipe member arranged to line the aperture, and the dust filter may be designed as a sound damper.
Inside the air lock there may be arranged a plurality of air guiding surfaces which extend longitudinally in spaced relation and are provided with sound damping material.
The air lock may also include heater elements and may be provided with means for sterilization and/or hb nidification of the air.
A sound damper may be installed in a pipe member which supports an entry grille and is separate from but aligned with a pipe member lining the opposite end of the aperture.
The separate pipe member and/or the pipe member lining the opposite end of the aperture may be provided with a wall perforation and the space remaining inside the wall aperture may be designed as a resonator.
The air lock may be of rectangular cross section and may be constituted by two substantially Ushaped parts, consisting of plastics material reinforced with glass fibre, and optionally provided with a sound damping lining.
The air lock may also include a pedestal member supporting the air fan, together with a driving motor and electrical control elements and may further include a head member, which supports the air discharge screen as well as electrical switching means, both said pedestal member and said head member being removably mounted.
The electrical control elements may be arranged in the pedestal member, and the electrical switching devices arranged in the head member, in each case being screened from the air flow space.
The partially closable screen may be provided with pivotable adjustable elements.
Some embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a side elevation of a ventilation apparatus according to the invention, shown in longitudinal section; Figure 2 is a similar ventilating apparatus having several guiding surfaces arranged in spaced relation as seen in front elevation, and shown partly in longitudinal section; and Figure 3 illustrates a dust filter and sound damper installed in an entry duct of the ventilating apparatus shown in Figures 1 and 2.
BEST MODES FOR CARRYING OUT THE INVENTION Referring to Figure 1 of the drawings, the ventilating apparatus comprises an air lock 1 of box column formation, the interior of which is lined with sound damping material 1 3. This air lock 1 is arranged to rest on the floor of a room to be ventilated and is located at a small distance from an exterior wall 5, in which is made a relatively small aperture 8. The aperture 8 is lined with a pipe member 9 having an inlet grille 10, and leading to an air fan 2 driven by a motor 3 and arranged at an opening in the lower wall of the box column. At the upper end of the air lock 1 there is located an air discharge aperture, which is open towards the room to be ventilated, and which is provided with an adjustable louvered screen 4, for example, of the type already known for use in power driven vehicles.
Extending over the entire cross-section of the air lock 1 there are fitted dust filter elements 6 through which the air stream is forced. Instead of or in addition to these air filters, a dust filter 6', optionally designed as a sound damper, may be arranged in the pipe member 9. Further dust filters 16, for example of plate form, may be provided for sterilising the air.
As can be seen in Figure 2 a plurality of guiding surfaces 7, provided with a covering of sound damping material, are arranged in spaced relation in the longitudinal direction of the air lock. With the object of preventing the formation of water or condensation, heater elements, for example electric heating wires, may be mounted on the walls or other parts of the structure.
As seen in Figure 1 the air lock 1 is of substantially square cross-section and comprises a pedestal member 1 a supporting the air fan 2 with the driving motor 3, and a head member 1 b supporting the air discharge screening means 4 and an electrical switching arrangement, both the pedestal member 1 a and the head member 1 6 being removable. The electrical control elements 11 in the pedestal member 1 a as well as the electrical switching arrangement 12 in the head member 1 b are screened by wall members from the air current.
Referring finally to Figure 3 a sound damper 14 can be installed in a pipe member 9' which supports the entry grille 10, and forms a separate component aligned with the pipe member 9.
By the provision of a wall perforation 9a in the pipe members 9 and/or 9', the remaining space within the wall aperture 8 becomes a resonator.
Finally the pipe members 9 and 9' can be interconnected by springs 15, whereby they are securely seated within the aperture 8 of the wall 5 and the buffer discs 5a and 5b. Furthermore additional dust filters 1 6, for example of plate form, may be provided, possibly for sterilizing the air.
