Definitions

  • the invention relates to a blower with a guide channels for the housing to be conveyed medium and with a rotatably mounted impeller with vane grille, which is accommodated in a block made of sound-absorbing material, such as porous plastic, and is surrounded by an approximately spiral-shaped boundary wall of the housing block. in particular to a built-in blower intended as a fan for installation in systems.
  • the invention is intended to remedy these deficiencies and, accordingly, to create a blower that develops a lower level of noise than the previously known blowers and can be installed without any problems even in confined installation spaces without appreciable impairment of the desired noise reduction with respective adaptation to the available installation spaces.
  • An expedient embodiment of the invention is characterized in that at least one of the housing cover plates receiving the housing block between itself also consists of sound-absorbing material, for example of a foam having a certain hardness.
  • a smooth, but sound-permeable lining can consist of a fiber flow applied to the sound-absorbing material and a smooth film covering the latter on the inside of the channel, or, according to another design feature of the invention, can be realized by "skin" of the surfaces facing the flow, at least of the housing block consisting of sound-absorbing material.
  • Another expedient embodiment of the invention is that, when it is designed as a built-in blower, the impeller is mounted with the vane grille on a support plate, which in turn is connected to the housing and is mounted via at least one elastically flexible element in an overall arrangement accommodating the blower.
  • This measure noticeably dampens vibrations and on the other hand prevents the transmission of structure-borne noise.
  • the Trag plate, on which the impeller is rotatably mounted can also be accommodated in an overall arrangement with limited elastic compliance via an end wall of the housing, this end wall then forming the elastically flexible element and consisting of sound-absorbing material with a predetermined elasticity.
  • the housing block consisting of sound-absorbing material extends essentially over the axial length of the impeller grille and contains the flow channels for the medium to be conveyed.
  • One of the front cover plates can be provided with a recess adapted to the hub of the impeller and the cover plate removed from it can have an axially directed inflow channel for the medium to be conveyed, which is adapted to the diameter of the impeller grille.
  • a housing made of the inner housing block made of sound-absorbing material and the front cover plates accommodating it between itself can be easily adapted to the available installation spaces in terms of size and shape because the sound-absorbing materials, such as porous plastic with a certain hardness, are extremely easy to machine.
  • the blower illustrated in the drawing is a radial blower 10, the impeller 11 of which is rotatably mounted on a support plate 14 with the blade grille 12 by means of a hub 13, which is only indicated, in a manner not of interest here.
  • the support plate 14 is in turn received on an elastic support plate support 15.
  • the housing consists of a middle part 16 and a hub-side and suction-side cover plate 17, 18.
  • a receiving space with an approximately spiral boundary wall 20 for the impeller 11 with the vane grille 12, which forms a channel enclosing the impeller and into the in the region of an end face of the middle part 16 of the outlet channel 21 emerging from the latter.
  • the hub-side cover plate 17 is equipped with a central recess 22 adapted to the diameter of the impeller hub 13 and the suction-side cover plate 18 has an axially directed suction duct 23 adapted to the inner diameter of the blade grille 12.
  • the elastic support plate support 15, the hub-side cover plate 17 and the housing middle part 16 consist of foam of a certain hardness and elasticity, which has proven to be an excellent sound-absorbing material.
  • the boundary wall 20 surrounding the impeller and the outflow channel 21 are coated with a fiber flow (not shown further) and the latter is covered with a smooth film on the inside of the channel.
  • a similar coating can be provided in the region of the side of the cover plate 17 covering the receiving space for the impeller on the one hand and the outflow channel 21 on the other hand.
  • FIG. 3 The assembly of the device is illustrated in FIG. 3.
  • the cover plate 17 on the end face of the housing is received between the elastic support plate support 15 receiving the support plate 14 and the middle part 16 of the housing.
  • the other end face of the housing is covered with the axially directed flow channel 23 by means of the cover plate 18 shown in FIG. 1 and not shown in FIG. 3.
  • the manner in which the housing parts are connected to one another and to the latter, the support plate 14 or the support plate support 15, which rotatably receives the impeller, is in itself indifferent and is therefore not shown further.
  • the individual components be connected to one another by connecting means arranged in the corner regions and extending coaxially with the impeller, or also, for example, by gluing.
  • the support of the blower in its entirety by means of the elastic plate 15 which, for example, bears against an abutment of an overall arrangement accommodating the blower.
  • blower housing essentially of easily workable, sound-absorbing material, such as porous foam of a certain hardness, it is particularly easy to adapt such a housing to the available installation spaces in terms of shape and size.
