Definitions

  • the invention is related to the field of building and ventilation technology, more specifically to ventilation windows.
  • WO 2014/098435 A1 discloses a window with a ventilation structure.
  • the window comprises a window frame having upper and lower openings which are divided by a horizontal member, and upper and lower window panes respectively mounted in the upper and lower openings for selectively opening and closing the upper and lower openings. At least a pair of the horizontal members are spaced apart from each other in the window frame, and a ventilation hole is disposed between the horizontal members.
  • the window can ventilate the indoor air smoothly without regard to weather conditions, and prevent rain from coming into the room through the open window.
  • Working or building the installation housing and waiting for the plastering to dry will extend the installation period and cause extra costs.
  • This kinds of ventilation devices are disclosed in German patent application publications DE 10 2011 055522 A1 and DE 10 2012 104198 A1 .
  • German patent application publication DE 32 00 113 A1 discloses a window in which the window frames have venting ducts in the longitudinal direction which are divided by means of heat-exchanging partitions.
  • the individual ducts are connected by means of air inlet and air outlet openings to the inside and to the outside. Venting ducts of different frames are interconnected by means of passages. The airflows directed from the outside inwards or from the inside outwards predominantly cross one another in the lower and upper frame limbs.
  • the ventilation device described in Skaala Oy's Finnish patent application 20135214 is more easily mountable than HAUTAU GmbH's ventilation machine, because the ventilation device described in patent application 20135214 is inside the perimeter formed by the frames, in which case no extra housings need to be made in the body structures.
  • the objective at present is to make an as large light opening area as possible in the window, which means that slimmer sashes need to be used.
  • the susceptibility of the sashes to various deformations grows.
  • any cuts and holes made in the sashes increase the possibility of deformations and problems resulting from deformations.
  • a first objective of the invention is to facilitate the installation of a ventilation window.
  • a second objective of the invention is to improve the tightness of a ventilation window.
  • the ventilation window comprises a) a frame, b) an outer sash arranged in connection with the frame, to which outer sash at least one pane is fastened, and c) an inner sash arranged in connection with the frame, to which inner sash at least one pane is fastened.
  • the outer sash and the inner sash are fastened to the frame or one of the sashes is fastened to the frame and the other sash is fastened to a sash fastened to the frame so that an intermediate space has been arranged between the outer sash and the inner sash.
  • the ventilation window comprises i) a ventilation device which has been installed or is to be installed inside the frame or on the surface of the frame on the side of the intermediate space, which ventilation device extends to the intermediate space, ii) at least one fresh air duct for leading fresh air from the exterior to the ventilation device through at least one inlet such as an orifice or nozzle located in the frame on the exterior side and from the ventilation device further to the interior as inlet air through at least one outlet such as an orifice or nozzle located in the frame on the interior side, and iii) at least one exhaust air duct for leading exhaust air from the interior to the ventilation device through at least one inlet such as an orifice or nozzle located in the frame on the interior side and from the ventilation device further to the exterior as waste air through at least one outlet such as an orifice or nozzle located in the frame on the exterior side.
  • the existence of the intermediate space can be utilised in the placing of the ventilation device. It may be possible to install a ventilation window comprising a ventilation device in a window installation opening that has been made in the body structure, where the installation opening does not have a separate installation housing, or an installation housing that is possibly needed can be implemented as a smaller installation housing.
  • a ventilation window comprising a ventilation device in a window installation opening that has been made in the body structure, where the installation opening does not have a separate installation housing, or an installation housing that is possibly needed can be implemented as a smaller installation housing.

  • the ventilation device When the ventilation device remains on the inside of the plane defined by the external edge of the frame when seen from the light opening area of the frame on the side of the ventilation device, it is not necessary to work an extra installation housing in a concrete body structure or it is not necessary to build an extra installation housing in a wooden body structure. In this way, it is possible to expedite the installation of the ventilation window.
  • the ventilation device When the ventilation device extends in the frame to a recess made in the frame on the outer edge of the frame when seen from the light opening area, it may be possible to better utilise the volume taken by the perimeter of the frame and/or to enable the accessibility of the ventilation device from the front of the ventilation window (in other words from the front of the ventilation window from the interior side) or from the back of the ventilation window (in other words from the front of the ventilation window from the exterior side).

  • the length of the frame-side arm of the hinges of the outer sash is most preferably 40 - 60%, most advantageously approximately one half, of the protrusion of the ventilation device from the surface of the frame on the side of the light opening area, it is possible to implement the hinging of the outer sashes so that the length of the arm of the hinge on the side of the frame does not essentially impair the functioning, carrying capacity and strength features of the hinge as compared to the use of ordinary hinges.
  • the length ratio of the arms has an impact on the opening arc of the outer sash.
  • a longer frame-side part reduces the corner reduction and enables installation in narrower windows (in other words in smaller widths).
  • a lengthening of the frame-side part takes the pivot point towards the light opening area, in which case the end of the outer sash on the side of the ventilation machine remains behind the pivot point and turns outward in connection with opening.
  • On the outside of the sash in turn, there is a facing frame sheet with seals. This prevents the pivot point from being taken too much towards the intermediate space.
  • increasing the size of the shaft of the hinge on the side of the sash increases the rotational radius (cf.
  • the arm on the side of the outer sash for the avoidance of the ventilation device should possibly be implemented as a longer arm, in which case it would bend more easily in connection with the washing of the outer side of the outer sash. It is also possible to implement the opening of the outer sash by means of a slide hinge/fitting to be installed in the upper sash and the lower sash.
