Definitions

  • the invention relates to a ventilation device, in particular for supplying air to rooms, with an electrically operated blower, which is accommodated in a housing, each having an air passage opening facing the room and an air passage opening facing away from the room, the blower having a drum-shaped rotor which is installed between two parallel longitudinal side walls of the housing.
  • both the fine or permanent ventilation systems and the forced ventilation systems are designed so that they shield the rooms to be ventilated against excessive outside noise.
  • the invention aims to eliminate all of the above-mentioned disadvantages in connection with the ventilation of rooms. It is therefore based on the task of taking precautions for rooms equipped with windows, in particular heat and / or soundproof windows, which allow use-dependent and needs-based ventilation of rooms with as little technical effort as possible, without disturbing ventilation noises occurring. These arrangements should be of such a nature that they can be taken without any major circumstances - even after the fact. H. also possible in the area of windows that have been installed in building walls for a long time.
  • the invention is based on a ventilation device, in particular for the air supply in rooms, with an electrically operated fan, which is housed in a housing, each having an air passage opening facing the room and an air passage opening facing away from the room, the fan being one has a drum-shaped rotor which is installed between two parallel longitudinal side walls of the housing, the rotor of the fan furthermore having a large diameter in relation to its length and the overall thickness of the housing in the direction of the rotor axis being smaller than the width of the free, room-side visible surface conventional window or door frame and / or sash profiles, and wherein at least one air passage opening is provided in a - transverse - housing transverse wall lying parallel to the axis of the rotor.
  • a ventilation device designed according to the invention can be created on the one hand with relatively small structural dimensions and minimal construction weight and on the other hand ensures a sufficiently large air flow even at relatively low rotor speeds of the blower without disturbing ventilation noises appearing.
  • a ventilation device can also be designed so that it does not have to be installed permanently on sash and / or frame profiles of windows or doors or roller shutter boxes, but rather as a more convenient and therefore more flexible or easily transportable device type can be designed, which is possibly available to every individual occupant of a building or every user of any room within this building for individual use and can therefore be used by him as needed.
  • a ventilation device with an overall length between 350 and 400 mm in length, an overall height of approximately 150 mm and an overall thickness between 20 and 50 mm can easily be designed for an air output between 15 and 25 m 3 / h if the blower is operated by a low voltage DC motor for the voltage range between 6 and 12 volts with 1,200 to 1,300 rpm. is driven.
  • the fan can be operated with its own noise that does not reach 30 dB (A).
  • a ventilation device can be designed particularly advantageously if the ratio of the length to the diameter of the fan rotor is approximately between 1: 5 and 1: 7.
  • fans with a rotor diameter between 90 and 120 mm can be used, for example, in which case the effective rotor length could be a minimum of 15 mm and a maximum of 22 mm.
  • an accumulator could be installed in the housing of the ventilation unit, which can be charged from the building's power supply via a transformer and / or via solar cells.
  • a transformer and / or via solar cells can be charged from the building's power supply via a transformer and / or via solar cells.
  • the second air passage opening can be arranged in a longitudinal side wall of the housing. This makes it possible to move the air required by the ventilation device in the interior of the room essentially parallel to the window plane, provided that the ventilation device with its air passage opening provided in the housing transverse wall has been adapted from the air passage in the frame and / or sash profile of a window.
  • both air passage openings are arranged in the same length section of the housing, which is remote from the blower rotor, and are shielded from one another by at least one intermediate wall extending up to the circumference of the blower rotor.
  • a further air passage opening is provided in a longitudinal side wall of the housing according to claim 5, which is located within the rotating circle of the fan rotor and faces the room.
  • This additional air passage opening not only makes it possible to operate the ventilation unit in mixed air mode, in which a certain proportion of room air is injected into the fresh air brought in from outside. Rather, in some cases it would also be conceivable to operate the ventilation device in pure recirculation mode if it is ensured that the air passage opening of the housing facing away from the room can be closed by a suitable shut-off element (flap or slide).
  • the further air passage opening can expediently be designed such that it can be opened and closed and / or its passage cross section can be changed in order to thereby enable the operating behavior of the ventilation device to be influenced.

  • the arrangement of these air passage openings is such that one of them always faces the room to be ventilated and another is turned away from it.
  • a filter insert is arranged interchangeably in the housing between the air passages facing the room and the air openings facing away from the room, which filter insert can preferably be exchanged through an opening in a housing wall and in each case the air passage opening facing the room can be placed in front of the housing.
  • the fan rotor is installed as a radial fan in the housing and axially connects with its suction side to a passage in an intermediate wall of the housing lying parallel to its plane of rotation, which between the space facing and the space facing averted air passage opening is arranged.

  • Another design option of the ventilation device according to the invention is characterized in accordance with claim 7 in that the fan rotor is installed as a tangential fan in the housing and is located directly adjacent to the air passage opening in the housing transverse wall between the two longitudinal side walls, and that the fan rotor above a portion of its circumference is encompassed by an intermediate wall lying transversely to its plane of rotation, which divides from the housing transverse wall containing an air passage opening and ends at a distance from the opposite housing transverse wall.
  • An important further training measure for such a ventilation device consists essentially in the fact that the air passage opening facing the room can be optionally opened and closed by a rotary flap.
  • a particularly advantageous embodiment of the invention is seen in that the rotary flap at the edge of a the air passage opening on its longitudinal and transverse edges delimiting semicircular trough, is designed as a flat plate and carries on both broad sides a larger number of spaced-apart and transverse slats, the free boundary of which is curved in accordance with the trough contour.
