Definitions

  • the invention relates to a fan assembly with shut-off device against fire transmission according to the preamble of the main claim.
  • shut-off device for ventilation systems in which a drop flap is provided which is guided in a frame provided with rails.
  • the frame is inserted on or in a wall and has an opening that is to be closed with the drop flap in the event of a fire.
  • the drop flap is held in the open position by a fuse, which melts when heated and falls due to gravity, so that the opening is closed off.
  • This design has the disadvantage that the shut-off device can only be installed vertically on walls but not horizontally on ceilings.
  • a fire shut-off device for an exhaust hood, in which a flap which can be pivoted or displaced by spring force parallel to the plane of a base plate is held in its open position by a fusible triggering device and closes in the event of fire due to the melting of the trigger device.
  • the publication does not provide more precise information on the triggering device.
  • the publication does not provide any teaching on a design of the device which ensures reliable functioning while at the same time simply enabling the regular functional tests of the locking mechanism which are required in such devices (required by law in Germany).
  • the invention has for its object to provide a fan assembly with shut-off device against fire transmission according to the preamble of the main claim, which enables rapid detection of increased exhaust air temperature as a result of a fire and simple regular function test.
  • the base plate of the shut-off device is used at the same time as a holder or mounting plate for the fan or an adapter connected to the fan, rapid and cost-saving assembly or disassembly of the fan and particularly rapid monitoring of the shut-off device are made possible. Due to the mounting holes in the base plate, which are designed as elongated holes, assembly can be carried out in alignment with the blow-out cross section, even if the fan is inclined.
  • the shut-off devices can also be installed with one of the fans according to the position of the pipeline in the transition area of the rooms in all positions of use.
  • the base plate 1 which is preferably made of steel, has bores 8 which, in the exemplary embodiment, are designed as elongated holes, via which the base plate 1 can be fastened to the wall or ceiling by means of screws.
  • an exhaust port 2 which is made of plastic, for example, is connected to the base plate 1 by a snap-fit quick coupling, wherein it is aligned with the opening 10 in the base plate 1.
  • the quick coupling is formed by punched and bent out of the base plate 1 tabs 9, which cooperate with the flange of the exhaust port.
  • a non-illustrated leak-proof check valve is integrated in the exhaust air connection 2, which prevents used air from flowing back into the space to be vented.
  • a pin 3 preferably made of steel, is arranged laterally to the exhaust air opening 10 of the base plate 1 and the latched exhaust air connector 2 and, as shown in FIG. 3, is connected to the base plate 1 by flanging or riveting or the like.
  • a locking plate 4 made of sheet steel is rotatably mounted on the pin 3.
  • a thermal release device 5 which serves as a retaining stop for the shut-off plate 4.
  • the shut-off plate 4 is prestressed by a spiral spiral spring 6 in such a way that it wants to move into a position in which the opening 10 is closed.
  • the thermal release device 5 prevents it from moving in this way.
  • the spiral spring 6 is arranged on the pin 3, the one end 11 of the spring 6 engaging in a stop plate 12 connected to the shut-off plate 4, while the other end 13 of the spiral spring 6 abuts a stop 14 connected to the base plate 1. In this way, the shut-off plate 4 is held in a biased standby position which does not restrict the exhaust air flow.
  • the thermal release device 5 consists of two stamped copper sheet parts 15, 16, which are held together by fusible link 7 with a melting point of 72 ° C.
  • the stamped part 15 projects into the exhaust air cross section or the opening 10 of the base plate 1 and acts as a temperature sensor for the actual temperature of the exhaust air stream flowing through.
  • the stamped part 16 is slightly bent at one end such that it overlaps the edge of the shut-off plate 4. In this way, the shut-off plate cannot slide over the triggering device 5 due to vibrations, for example, and can cause an undesired closing of the exhaust air line.
  • the trigger device is constructed as a unit and can be positively connected to the base plate 1 by means of hooks 17 and eyes 18 arranged on the base plate 1 or the trigger device 5.
  • the base plate 1 according to FIG. 1 has bent tabs 30 and at least one detent spring 31, which serves to hold the housing of a fan 19.
  • the base plate 1 with the shut-off device is screwed to the wall 21 of an exhaust duct 22 via screws 20, in which the exhaust air duct 23 is guided.
  • the exhaust air line 23 is provided with a flexible connecting line 24 which is placed on the exhaust air connector 2.
  • FIG. 5 shows a further exemplary embodiment of the fan arrangement with a shut-off device for ceiling mounting.
  • the fan unit 25 is mounted directly or in a housing box on the ceiling via connecting elements 26.
  • the base plate 1 is again attached to the wall 21 of the exhaust duct 22.
  • the base plate 1 serves as a holder for an adapter 27, which consists of a plastic plate with attached connector.
  • the adapter 27 is placed on the tabs 30 of the base plate 1, and the detent spring 31 engages in a recess in the adapter.
  • a flexible connecting line 28 is pushed onto the connecting piece and is connected to the fan outlet, in front of which a non-return flap 29 is located.
  • the fan arrangement is covered by a grid ceiling 32.
  • shut-off plate 4 is pivoted about the pin 3 in the plane of the base plate 1 in such a way that the opening 10 is closed.
  • Guides 33 which are punched out and bent out of the base plate 1, guide and limit the shut-off plate 4 during its pivoting movement, so that it is aligned with the opening 10. This prevents the transmission of fire and smoke in the cross-section of the exhaust air opening from the ventilated room into the pipe system of the ventilation system in both directions.
  • a stop 34 is provided which, similar to a tab, also from the Base plate 1 is punched out and prevents the locking plate 4 from moving back from the locked state.
  • the base plate is arched in the area indicated by the boundary line 35 toward the room or the fan unit in order to ensure that the shut-off device works properly.
  • the shut-off device can also be used in connection with fire protection boxes, flanged into or screwed onto it, so that a defined fire closure is formed.
  • the entire opening and tube cross section remains free except for the temperature sensor protruding into the opening.
  • Different pipe diameters are possible by using the shut-off plate.
  • the fan can be designed as a roof fan, which is connected to the individual rooms via ventilation lines.
  • the adapter is designed as a grid, which is attached in front of the wall opening and is connected to the base plate.
  • the fan can thus be arranged in front of or behind the shut-off device in accordance with the different types, the shape and design of the adapter also being able to be adapted to the particular circumstances of the air supply or removal.
