A request for correction of the description (replacing "...duct connectors 2, 5, 6,
7..." by "...duct connectors 3, 5, 6, 7...") has been filed pursuant to Rule 88 EPC.
A decision on the request will be taken during the proceedings before the Examining
Division (Guidelines for Examination in the EPO, A-V, 3.). |

[0001] The present invention concerns a ventilating apparatus.
[0002] Apparatuses of the mentioned type are mounted outside the room or rooms that shall
be ventilated or the apparatuses are mounted within the room itself or in connection
with the room. In both cases ducts may be drawn to the apparatuses for extract air,
exhaust air, outdoor air and supply air respectively and many times ducts are drawn
from different places to the apparatus and after that around the apparatus itself
in order to be connected to an inlet of the apparatus.
[0003] Such a design leads to extra many and long ducts.
[0004] With the ventilating apparatus according to the present invention a substantial simplification
of the mounting of ducts to the apparatus is achieved. This is achieved with the ventilating
apparatus according to the present invention such as it is defined by the characteristics
mentioned in the claims.
[0005] In the drawing figure 1 shows a sketch in principal of known designs, figure 2 shows
the corresponding sketch in principal for the apparatus according to the invention,
figure 3 shows an apparatus from above, figure 4 shows the apparatus in figure 3 seen
from below, figure 5 shows a connection sleeve coupling and figure 6 shows a dead
end cover.
[0006] The ventilating apparatus 1 according to the present invention in both ends of the
apparatus 1 comprises duct connectors 2 and 6 respectively for exhaust air and duct
connectors 5 and 7 respectively for outdoor air. This leads to the fact that the connection
of the ducts may be done on that side of the apparatus 1 that is most suitable in
relation to the duct extension. In the duct connectors that are used connection sleeve
couplings 8 are inserted which connection sleeve couplings are mounted to the duct
connectors with a bayonet grip. The duct connectors that are not used are closed with
dead end covers 9 which in the same way are entered into the duct connectors in the
ventilating apparatus and locked with a bayonet grip.
[0007] The ventilating apparatus 1 according to the present invention is delivered with
duct connectors 2, 5, 6, 7 in both ends and connection sleeve couplings 8 are mounted
in the connectors that are to be used for connection of ducts while other connectors
are closed with dead end covers 9.
[0008] While it is possible to use duct connectors in both ends of the ventilating apparatuses
1, both up and down respectively, either up or down or both up and down, this leads
to a substantial simplification of the duct extensions to and from the apparatus 1
since it is no longer necessary to draw ducts around the apparatus in order for them
to reach and be connected to the right duct or sleeve coupling which is the case with
the known designs.
[0009] The ventilating apparatus 1 may be produced as a standard and be ordered as such
while the selection of duct connectors for connection sleeve couplings 8 or dead end
covers 9 may be done on the building site. This leads to reduced production costs
and logistics costs in total among other things due to fewer variants of apparatuses.
Several duct pieces are also saved which gives lower costs for the duct system in
total and later on a lower energy consumption during operation due to a shorter transport
of the air.
[0010] With the ventilating apparatus according to the invention a shorter time for mounting
is also achieved due to fewer duct pieces. The principle with a unity apparatus is
withheld with the simplicity this involves.
[0011] The ventilating apparatus according to the invention may be freely mounted laterally
or horizontally and both in warm and cold surroundings, for example on a wall, in
cold attics or eventually be hanged in the ceiling.
1. Ventilating apparatus comprising connectors for ducts, characterized in that the connector (3) for exhaust air in the first end of the apparatus is in direct
connection with a further connector (6) for exhaust air in the second end of the apparatus
through the inner of the apparatus and that the connector (5) for outdoor air in the
first end of the apparatus is in direct connection with a further connector (7) for
outdoor air in the second end of the apparatus through the inner of the apparatus.
2. Ventilating apparatus according to claim 1, characterized in that two connection sleeve couplings (8) and two dead end covers (9) are delivered with
the apparatus for connection of two ducts to two connectors and closing of two connectors.
