Definitions

  • the present invention relates to a device for venting a cavity, in particular a basement or a living space, according to the preamble of claim 1.
  • fans with which air can be blown in a certain direction or can also be passed into a cavity.
  • fan blades are attached to a hub and surrounded by a fan housing having a suction side and a discharge side.
  • the motor for driving the hub and the fan blades is arranged in the region of the rotational axis of the hub.
  • a ventilation device is for example from the DE 297 23 738 U1 known. If such fans are to be used to extract hot air from the source of the fire in the event of a fire, there is the problem that the hot air flowing past the engine heats the engine.
  • the invention has for its object to provide an improved device for venting a cavity such as a basement or a living room, with which the aforementioned disadvantages are overcome and is easy to use and versatile.
  • a cover assembly can be mounted on the suction side, whereby a part of the suction side is covered.
  • This cover assembly has at least one opening to which a relatively slender suction hose can be connected.
  • the free end of the suction hose can then be easily moved to the suction, such as a fire in a cellar.
  • the device according to the invention sucks very selectively at a desired location.
  • the extracted hot air is not passed by the motor of the fan and heats it up, but the engine is intensively cooled by the air flowing past this, which is sucked into the venting device via the surface of the suction side not covered by the cover assembly.
  • a particularly good compromise between exhaust performance and sufficient cooling of the engine is achieved when the cover assembly covers 20 to 80% and preferably about 40 to 60% of the area of the suction side.
  • the operation of the device according to the invention is substantially facilitated by the relatively small diameter suction hoses.
  • the cover assembly can be easily attached by means of a quick release on the fan housing or mounted by means of a hinge to the fan housing pivotally. Handling is further improved when each suction hose is fastened to the cover assembly with a quick-release fastener.
  • the transport and storage of the device according to the invention can be simplified if the fan housing is designed as a winding drum for the suction hose or the suction hoses.
  • the handling of the cover assembly is more flexible if it is divided into at least two cover parts, to each of which a suction hose can be connected via an associated opening.
  • the engine is cooled particularly well, when the cover parts are each mounted at an equal angular distance from each other.
  • the attachment of the cover and the connection of the suction hoses to them is particularly easy to do, if two cover parts are provided, which are each arranged laterally on both sides of the motor, that is, each other horizontally opposite each other.
  • a particularly high suction performance with good cooling of the engine can be achieved if three cover parts with a pitch of 120 ° (and intermediate free ring segments) are arranged from each other.
  • a cover with the associated Suction hose below and the other two cover parts are arranged horizontally opposite each other further up.
  • cover parts are ring-like segments, wherein the outer contour of these segments is defined by the fan housing of the axial fan and the inner boundary of these segments is defined by the housing of the motor, which does not necessarily have to be cylindrical and thus slightly modifies the ring shape of the segment ,
  • Fig. 1 shows a first embodiment of the venting device 10 according to the invention, in which the cover assembly 30 in three cover parts (also called Hutzen) is divided 31 to 33.
  • the cover members 31 to 33 are each as ring segments with a Angle coverage of 90 ° formed, whereby about three quarters of the suction side are covered.
  • the three cover parts 31 to 33 each have an angular distance of 120 ° from each other and are by means of here only indicated quick fasteners 52 -. B. in the form of snap fasteners - attached.
  • the only schematically indicated fan blades 12 are only partially covered by the cover parts 31 to 33, and also the fan blades 12 bearing hub 14 and arranged in a housing 22, motor 20 are also shown only schematically, since these components correspond to a conventional axial fan.
  • Openings 34, 35 and 36 are now provided in the cover parts 31 to 33, via which respective suction hoses 37, 38 and 39 can also be connected by means of quick-release fasteners 36 (for example locking, screw or bayonet locks) which are also shown only schematically.
  • quick-release fasteners 36 for example locking, screw or bayonet locks
  • venting device 10 is formed as an axial fan, which is shown from its suction side 17 forth, wherein the direction of movement of the sucked through the suction hoses 37 to 39 of the desired suction air is indicated in each case with an arrow A.
  • the suction side 17 is sucked according to the arrows B in the venting device 10 and thereby cools the drive motor 20, after which they at the outlet side 18 (see. Fig. 2 ) is blown out again.
  • Fig. 2 shows in plan view a second advantageous embodiment of the venting device 10 according to the invention in a housing 22, a motor 20 is mounted, which drives a hub 14 via a drive shaft 13 to which the fan blades 12 are attached. These fan blades 12 are surrounded by a funnel-shaped fan housing 16, which is shown here conically for the sake of simplicity.
  • the motor 20 is arranged on the suction side 17.
  • the cover assembly 40 is divided in this embodiment only in two cover parts 41 and 42, which at an angular distance of 180 ° from each other (in the drawing plane above or below, which corresponds to a lateral arrangement left and right of the motor 20) is arranged.
  • the cover member 41 has an opening 44
  • the cover member 42 has an opening 45.
  • suction hoses 47 and 48 can be connected to the cover 41 and 42, which in turn fire air can be sucked, which by respective arrows A is specified.
  • fresh air is sucked into the fan above and below the motor 20 at the areas not covered by the cover parts 41, 42, which is indicated by dashed arrows B.
  • the sucked fresh and blast air is blown out on the outlet side 18 together according to a double arrow C in directed, laminar outflow.
  • the cover members 41 and 42 are pivotally attached to the fan housing 16 by means of hinges 54 only shown schematically.
  • the funnel-shaped fan housing 16 can also be used to wind up the relatively slim suction hoses 47 and 48 when they are separated from the cover parts 41 and 42, respectively, by loosening the quick-release closures 56, which are shown only schematically.
  • these two cover parts 41 and 42 are also formed as ring segments and each cover an angular range of 80 °, thereby a coverage of about one third of the suction side 17 is achieved.
  • a coverage of one third to two thirds, preferably about half, of the suction side 17 should be optimal.
  • the venting device 10 can be located relatively far from the point to be vented (and possibly very hot in case of fire), whereby the suction power is not affected at the desired location, because the suction effected by the suction tubes connected to the covering very targeted and efficient becomes.
  • the ventilation device 10 according to the invention is very versatile, since the suction hoses can also be easily introduced into sewer or basement manholes or through windows or doors of a living room, in addition their length can be varied by coupling several hoses.
