Definitions

  • the invention relates to a ventilation device for an individual ventilation system according to the preamble of claim 1.
  • Individual ventilation systems are understood to mean systems in which a large number of ventilation devices each have their own branch line to the common one Main line are connected.
  • the ventilation devices for such individual ventilation systems represent independent units that can work together or independently of the other units.
  • the ventilation devices are each equipped with their own fan.
  • Single ventilation systems with a common main line are mainly used for the ventilation of windowless rooms in buildings.
  • Such rooms are mostly sanitary rooms such as bathrooms, toilets or the like. However, other rooms such as kitchens, storage rooms or the like can also be used for ventilation.
  • the main line is arranged in a vertical shaft of the building, which is usually designed as a supply shaft.
  • the main line ends in an outlet or a chimney in the roof area of the house.
  • the branch line with which the connection between the housing and the main line is established, usually consists of a so-called "flex tube”.
  • the existing fire damper in such ventilation devices is used to prevent in the event of a fire that hot fire gases through the ventilation device and the stub pipe get into the riser pipe and thus possibly into other connected rooms and can thus cause the fire to spread.
  • the fire protection flap is arranged between the fan of the ventilation device and the spur line. In this way, the combustion gases can be prevented from entering the ventilation riser pipe from the burning room.
  • the majority of the fan in the event of a fire is fully exposed to the hot fire gases even after the fire damper is closed.
  • the entire ventilation device must always be removed in order to be able to reach the fire damper.
  • the fire damper is to be checked for its effectiveness without previous fire, which is necessary from time to time.
  • a fire protection device has already become known in the case of individual fans, which has a flap designed as a drop flap behind the intake grille of the front panel.
  • this fire protection device can only be accommodated in a large housing, so that the appearance of the fan from the front, that is to say from the side of the room to be ventilated, is not ideal.
  • the installation of the housing is only possible in one position because of the function of the drop flap, which must always be arranged pivotably about a horizontal axis.
  • the front panel has to Special dowels are anchored to the wall, which further affects the appearance from the room and requires increased installation effort.
  • an extractor hood which can be used in kitchens or the like is known and is essentially formed by a base body, a base and a cover.
  • a connection piece is attached to an opening, which leads to the extraction of the captured kitchen fumes to an extraction line.
  • a fan is normally installed in the housing, which pushes the kitchen fumes to the exhaust line through a nozzle.
  • a rectangular perforated plate is fitted horizontally in Schierer under the cover to seal the discharge nozzle and is held in the normal state by a fuse against the tensile force of a spring so that the opening formed in the perforated plate lies exactly below the circular opening of the exhaust air nozzle.
  • the invention has for its object to further develop a ventilation device of the generic type in such a way that, while maintaining the advantages of a fire damper arranged in front of the fan, the ventilation device can be installed with little assembly effort in practically any position and a shapely design of the ventilation device.
  • the invention is based on the idea of providing the fire damper on the front of the ventilation device, which is intended for installation in a wall or ceiling, close behind the filter arrangement, in order to facilitate easy filter change on the one hand and good accessibility of the fire damper for inspection without major dismantling work to enable.
  • a ventilation device of the type according to the invention is built very flat, so that practically any shape and design is possible is.
  • the flat plate is designed as a type of slide which can be moved in a straight line on the front wall of the housing from its open position into the closed position via guides.
  • the flat plate is arranged on a lever and can thus be pivoted from its open position into the closed position on an arc. Both types have the advantage that they can be made relatively flat and therefore only require relatively little space perpendicular to the plane of the front wall.
  • the front wall of the housing can also carry a plate made of heat-resistant material for further fire and sound insulation.
  • the reference numeral 1 denotes the housing for a ventilation device, in which a fan with a motor and fan blades is arranged.
  • the motor and the fan blade and the part of the housing 1 which extends to the left in FIG. 1 have been omitted for the sake of clarity.
  • the housing 1 is embedded in a masonry that its right edge in Fig. 1 is flush with the wall.
  • the housing 1 is anchored in the wall with claws 10. Starting from the housing part, not shown, the housing 1 is connected to the main line, also not shown, via a connecting piece and a spur line.
  • This housing front wall 3 can consist of a sheet metal plate provided with a bent edge. Within the bent edge, on the side of the fan blade, not shown, a plate 21 made of highly heat-resistant material, e.g. Asbestos. This plate 21 can serve the additional fire retardancy, but also the further sound insulation of the engine and fan noise.
  • a passage 15 for the air to be extracted from the room to be vented In the present exemplary embodiment, the part of the electric motor (not shown) protrudes into the passage 15.
  • straight guides 7 are fastened parallel to one another and have a double cranked, Z-shaped cross section and such a distance have from each other that between them the flat plate 8 of the fire protection device is easily moved back and forth.
  • a guide rod 5 is attached to the front wall 3 of the housing by means of two rod holders 13, 14 and is surrounded by a compression spring 6.
  • the rod holder 14 located at the top in FIG. 2 serves as a first spring abutment for the compression spring 6.
  • the second spring abutment is formed by a part 9 projecting at right angles from the flat plate 8, through which the guide rod 5 extends. In this way, the plate 8 is additionally guided on the guide rod 5.
  • the plate 8 itself can be moved back and forth in a straight line so that in an end position, in which it strikes end stops 7a in the plate guides 7, it completely covers the passage 15 in the front wall 3 of the housing and in the plate 21, thus closing this passage . In its other end position, it completely clears the passage 15.
  • the compression spring 6 strives to move the flat plate 8 into its closed position in contact with the end stops 7a of the plate guides 7.
  • a slightly melting part 12 acting as a thermal release device is fixedly arranged, which protrudes beyond the adjacent plate guide 7 into the path of the flat plate 8 and is thus able to counter this plate Force the spring 6 to lock in its open position.
  • the part 12 consists of a material that is strong enough on the one hand to perform the function mentioned, but on the other hand melts at a certain temperature, about 72 ° C.
  • the part 12 can also be designed as a bimetallic strip which deforms approximately at the temperature mentioned so that it releases the path of the flat plate 8.
  • a e.g. attached as a leaf spring end position securing 11 which then lies with its free end behind the folded rear edge 8a of the flat plate 8 when it is in its fully closed position.
  • a perforated front frame 4 which is removably attached to the housing and which contains a filter material 4a, serves as a cover for the ventilation device to the space to be vented.
  • a cover grille with a soundproofing filling which is also made of a highly heat-resistant material (e.g. asbestos) and thus also has a fire-retardant effect.
  • the plate guide 7 and the guide rod 5 can be arranged obliquely on the sound insulation wall 3, e.g. diagonally, as shown in Fig. 3.
  • the part forming the release device melts.
  • the plate 8 is no longer locked and is held by the force of the spring 6 moved up to the stops 7a in the plate guides 7. This position corresponds to the complete closing of the passage 15.
  • the free end of the end position safety device 11 which is designed, for example, as a leaf spring, falls behind the surface of the flat plate 8 in the open position under slight spring pressure the folded rear edge 8a of the plate 8. As a result, the flat plate 8 is locked in this position.
  • the hot (fire) gases are prevented from penetrating further into the interior of the fan, for example up to the heat-sensitive motor or even via the connecting piece and the branch line into the main line.
  • the plate 21 behind the housing front wall 3 causes less heat energy to get into the space behind the housing front wall 3, so that the risk of ignition of the engine and any grease residues or other combustible materials in the subsequent pipe system is reduced. Due to the hot (fire) gases and the resulting thermal energy, the attachment frame 4 and the protective grille in front of it in Fig. 1 to the right of the front wall 3 of the housing can be destroyed, but not the interior of the ventilation device itself Fire in other rooms connected to the main line can be prevented.
  • a flat plate 16 in the form of a disc is used for closing the passage 15 instead of the flat plate 8 which can be displaced in a straight line and spring-loaded manner is than the diameter of the passage 15.
  • the disk can be circular.
  • This disc is attached to one end of a lever 17, the other end of which is fixedly connected to an eccentrically to the center of the passage 15 and perpendicular to the housing front wall 3 in this shaft 18.
  • the length of the lever 17 and the location of the mounting of the shaft 18 in the front wall 3 are selected so that the disk 16 can be pivoted around the shaft 18 into a position against the stop 24 in which it closes the passage 15 (in Fig.
  • a thermal release device designed as a strip 22 made of an easily meltable material is also fastened, in such a way that it opposes the tension of the disc 16 on the other side of the front wall attached tension spring 20 holds in its "open position".
  • the thermal release device can have a bimetallic strip instead of the strip 22 made of easily meltable material, which locks the disc in its open position at normal temperature. If the room temperature increases beyond the permissible level, the strip 22 of easily meltable material melts and thus releases the pivoting path of the disc 16 into the closed position or the bimetal strip bends so that the pivoting path of the disc 16 also is released.
  • a plate 21 can be attached, which also fulfills both fire protection and sound insulation tasks and is made of a highly heat-resistant material.
  • the parts 19 and 20 are correspondingly further out.
  • the mode of operation of the second embodiment corresponds analogously to that of the first embodiment:
  • the disk 16 In the normal operating position, that is to say in the position in which the pivotable disk 16 clears the passage, the disk 16 is located, for example, in one shown in FIG Location.
  • the spring 20 endeavors to bring the disk 16 via the lever 19, the shaft 18 and the lever 17 in the direction of the arrow 23 into the position shown in dashed lines in FIG. 4, in which it rests on the stop 24.
  • the disc 22 is prevented from this pivoting movement by the strip 22 made of easily meltable material or by the bimetal strip which lies in the pivoting path of the disc 16.
  • the thermal release device or the corresponding bimetallic strip which is designed as a strip of easily meltable material, melts and the disk 16 is brought up to the stop 24 by the tensile force of the spring 20, as a result of which the passage 15 is closed.
  • the fan motor and the space behind it can only come into contact with hot gases to a very limited extent, so that there can be saved on insulating material. It is also an advantage that the part of the fan facing the room to be ventilated can be made very flat and therefore elegant. In addition, the claimed design enables much better sound insulation.
