Definitions

  • the invention relates to a cross-flow fan the preamble of claim 1.
  • Cross-flow fans according to the generic term are already known from GB-A-1 213 582 and FR-A-1 427 356.
  • the previously known ventilation devices show one Cross-flow fan, consisting of a pressure chamber comprehensive guide element, a separation between the suction chamber and Pressure chamber and at least one rotatable in side panels mounted fan roller with approximately parallel to the axis of rotation running blade edges, where the guide element starting from a line of closest approximation to the The circumference of the fan roller is preferably continuous increasing distance from the circumference of the fan roller.
  • the guiding element encompassing the pressure chamber is the inner one Boundary surface one from the top of a frame-like Plate or similar worn hood.
  • the attachment takes place in or by a Cutout or opening in the plate or disc.
  • the cutout also sits the cross flow fan, so that on the one hand, the installation space is cramped or by the encompassing flanges is additionally narrowed.
  • the assembly is made more difficult by additional fasteners od. Like. Are to be provided. At the same time they wear Sections of the cross-flow fan into the room and disturb the overall visual impression.
  • the disadvantage here is that the attachment of the hood to the Panel is only possible via an adhesive connection. Thereby is the assembly of such a ventilation device an existing panel is more complex and subsequently no longer detachable.
  • Cross-flow fans of a similar type are also, for example known from DE-PS 14 28 071 and DE-OS 24 14 610.
  • cross-flow fans are mainly used Cooling electronics, personal computers, copiers and Office machines as well as for the entire IT technology. Despite high Air performance they have a long lifespan and offer furthermore the possibility of point and Area ventilation.
  • the task is therefore to make a cross-flow fan simple and inexpensive to manufacture, and easy assembly allow it on a panel or the like.
  • a roof, a ceiling or a panel or the like be attached.
  • the cross-flow fan 1 shown in FIG. 1 of the drawing works with at least one by one (not shown) Electric motor rotating driven fan roller 2 and is there with a guide element 4 and a pressure chamber 3a one this pressure chamber 3a against a suction chamber 3b delimiting separation 5.
  • the fan roller 2 is with a ring of blades equipped, the blade edges approximately parallel to Axis of rotation are aligned.
  • this is the pressure chamber 3a Guide element 4 shaped so that it is from a line 6 of greatest approximation to the scope of the fan roller 2 with preferably increasing distance from the fan roller 2 removed and in the conveying direction of the air around considerable dimension over the diameter of the fan roller 2 is led out.
  • the guide element 4 comprising the pressure chamber 3a forms the inner boundary surface of one from the top of a plane Plate, a panel or a panel 7 worn hood 8.
  • the flat plate, the board or the panel 7 is included provided at least one cutout 9 through which they or it gets a frame-like shape.
  • the cutout 9 is overlapped overall by the hood 8, which preferably as a deep-drawn molded part made of sheet metal or can be made of plastic material and itself firm and tight on the top with the plate, the board or the Panel 7 can be connected.
  • the hood 8 which preferably as a deep-drawn molded part made of sheet metal or can be made of plastic material and itself firm and tight on the top with the plate, the board or the Panel 7 can be connected.
  • the inner one can be used immediately Boundary surface of the hood 8 itself that the pressure chamber 3a comprehensive guide element 4 form.
  • the hood 8 on its inside with a molded body 10 made of sound absorption and / or thermal insulation material, hard foam, for example, the inner Boundary surface the guide element comprising the pressure chamber 3a 4 forms.
  • the molded body 10 made of sound absorption and / or thermal insulation material down to the Section 9 of the flat plate, panel or panel 7 reaches in and there against a longitudinal part of the inner Frame edge 11 supports.
  • the fan roller 2 can in the area of the cutout 9 of the frame-like flat plate, panel or panel 7 in usually be installed so that they are constantly with one Circumferential part protrudes over the bottom thereof.
  • This peripheral part of the fan roller 2 is from a air permeable overall, e.g. a perforated grid containing, shielding recess 13 added, which releasably the underside of the plate, board or panel 7 is held. She can preferably go there with her Edge edges in a groove 14 running around the cutout 9 be included.
  • the pressure chamber 3a of the cross-flow fan 1 connects to an outlet opening 16 of the hood 8 on, for example, with the help of a Flap can either be released or closed. It is important that the flap 17 over a Hinge element 18 is mounted on the hood 8 so that it in its fully open position essentially as a straight Extension of the end adjacent to the outlet opening 16 of the guide element 4 or molded body 10 continues to run.
  • a separation 5 between the suction chamber 3b and the pressure chamber 3a of the cross-flow fan 1 can be a profile 15a, for example made of metal or plastic. This is, as is clear from Fig. 1, in the area of Outlet opening 16 of the hood 8 with an obtuse angle to Pressure chamber 3a into wall part 22 directed into hood 8 the hood 8 brought into holding engagement.
  • Fig. 1 it can also be seen that the pressure chamber 3a of the Cross-flow fan 1 itself at an outlet opening 16 of the hood 8 connects, which with the help of a flap 17 optionally can be released or closed, the flap 17 on the one hand over a lying on its upper edge Hinge element 18 is mounted on the hood 8 while it on the other hand, over the bottom edge with the slanted into the hood 8 protruding wall part 22 above the profile 15a cooperates.
  • the shape of the inner forming the guide element 4 Boundary surface of the hood 8 and the molded body 10 and also that of the profile 15a serving as separation 5 also all other design features of the cross-flow fan 1 can be optimized in a known manner so that not only a good air performance characteristic is achieved, but itself also a compact design and quiet operation of the Cross flow fan 1 results.
  • the cross-flow fan 1 shown in FIG. 2 can also be used the top of the hood 8 and the bottom of the Shielding trough 13 supporting, flat plate, or board or the panel 7 on the outer frame edges 19 in recordings, e.g. Folds, rails or the like are used, which a passage, an opening, a cutout od. Include or include in a room boundary. This can e.g. from a wall, a ceiling, a door, a floor, a roof, a window of a building, but also from one Housing, a closet, etc. exist.
  • the hood 8 is fastened to the panel 7 in accordance with 1 by integrally from the bottom of the plant or Support flange 25 protruding knobs 26, which in corresponding Immerse the holes 27 in the panel 7.
  • the one-piece Execution of hood 8, support flange 25 and knobs 26 will achieved by the production as an injection molded part, wherein the hood 8 is removed from the mold in the direction of the knobs 26.
