Abstract

The invention relates to a continuous ventilation system for aluminum or plastic windows, whereby the system is integrated in a window frame having a large outer pre-chamber on the frame profile.

Description

Modern, due to their sophisticated sealing systems, very tightly closing plastic and aluminum windows require continuous ventilation in order to provide a certain minimum supply ventilation of the room and minimal air exhaust from it even with the window closed.

For this purpose, it has already been proposed to install openings or perforated seals or also cut out seals between separate window frames and window sashes, or to incorporate fans on separate window frames or in the sash in glass.

However, provided with openings and cut out seals, however, there is not sufficient passage for air. The resulting air infiltration through the seams is in practice insufficient to meet hygiene requirements. In addition, whistled noises are created with these openings and cut out seals, which are very disturbing and therefore unacceptable to users.

With installed fans located in a certain area of the upper cross member of the separate frame, although there is more passage for air, drafts appear. If, finally, the fan is built into the glass, then the glass area is reduced and the flow of light is reduced. In addition, these installed or built-in fans cannot be brought into line with the required soundproofing.

Therefore, the invention is based on the task of creating a continuous ventilation system for aluminum or plastic windows, which, with a simple design, provides high air exchange and at the same time high quality sound insulation.

To solve this problem, in accordance with the invention, it is provided that the continuous ventilation system is integrated in a separate window frame with a large external prechamber on the profile of the frame, in particular, is configured so that the forechambers of the cross members of the separate window frame are interconnected as communicating vessels, and in the lower prechamber the cross member has a suction hole, and in the prechamber of the upper cross member there are connecting holes, the latter being included in the ventilation profile installed on the upper cross member of the separate window frame l with the outlet openings on the inside of the room.

The embodiment according to the invention provides particularly favorable air exchange already because the suction openings are made at the lower end of the window and the exhaust openings are made in the interior space at the upper end so that there is a very good draft effect. The incoming cold air when heated up is heated in the side racks of the frame so that it is already heated out on the inside of the window. This eliminates not only a draft, but also prevents fogging of the window. In addition, this method of supplying air in large pre-chambers of the separate frame profiles has the advantage that the sound insulation specified by the suitably executed frame profiles is not disturbed by the open path of continuous ventilation. The long path from the suction openings in the lower cross member of the separate frame through the side struts of the frame to the upper cross member of the frame and, finally, into the installed ventilation profile, provides due to many turns, as before, very good sound insulation. But the quality of soundproofing of the windows is crucial in view of the ever-increasing noise load of the environment, in particular for buildings near streets or factories.

Moreover, in an embodiment of the invention, it can be provided that the suction openings are located at the lowest point of the prechamber of the lower cross member of the frame, which also has the advantage that there are no problems with penetrating showers and that possible condensate can be discharged directly through these suction openings outwards on the windowsill.

In an improved embodiment of the invention, it can be envisaged that a replaceable filter, in particular a pollen filter, is used in front of the vents of the ventilation profile, and it is especially advantageous for the ventilation profile to extend along the entire length of the upper cross member of the frame.

The prechamber can either be made directly on the profile of the split window frame or formed by a separate mounted on the profile of the split frame, in particular, a thrust profile.

Other advantages, features and details of the invention result from the following description of two exemplary embodiments of the invention, and also with reference to the drawing. Shown:

FIG. 1 is a vertical longitudinal section of a separate frame made in accordance with the invention of the window;

FIG. 2 is an enlarged partial sectional view of the upper cross member of the frame; and FIG. 3 - corresponding to FIG. 2 is a section through a window with a modified ventilation profile mounted on the upper cross member.

Shown in FIG. 1 and 2, a separate frame 3, which is integrated in the masonry window opening 1 indicated only schematically, 2 consists of profiles 4, preferably made of plastic, which, in accordance with the invention, are provided with a large chamber 5. In the shown embodiment, this prechamber 5 is made on the profile 4 of a separate frame. But it can also be formed by a separate profile, which is installed on the profile 4 of a separate frame. Like the upper crossbar

6, both the lower cross member 7 and, of course, also the side posts 8 of the separate frame are provided with a prechamber 5 in accordance with the invention, the prechambers of all the cross members and the pillars of the frame are interconnected like communicating vessels, as indicated by the dot-dash line in FIG. one.

The prechamber 5 of the lower cross member 7 of the separate frame 3 at the lowest point is equipped with suction openings 9 for air, which at the same time can serve as exhaust slots for condensate that may form in the frame. On the upper cross member 6 of the separate frame 3, a ventilation profile 10 is installed, communicating through the connecting holes 11 in the chamber 5 of the upper cross member with the latter. Outlets 12 are provided on the interior side of the window relative to the room, in front of which a pollen filter 13 can be installed, preferably replaceable. Only the strokes indicate the window sill 14, which can be held with the help of the specified window sill 15. The air drawn in on the outside of the window through the suction slots 9 rises along both side racks 8 of the separate window frame 3 along their forechambers upwards and enters the prechamber 5 of the upper cross member, from where it the connecting holes 11 and the ventilation profile 10 enters the outlet openings 12 into the room. There the air comes out already warmed up so that there is ventilation without draft, and the main ventilation in winter can be carried out without interruption.

By milling the prechamber 5 of the lower cross member 7 to create air suction holes 9, the thermal insulation (K value) of the separate frame is reduced. Depending on the stated requirements for thermal insulation for this purpose, a heat-insulating wedge 22 can be installed in the chamber 21 formed by the internal stiffness wall 20, which has a good effect on sound insulation. For this reason, it may be necessary, if necessary, to provide such heat-insulating foam wedges in the chamber 21 of the pre-chambers 5 along the perimeter of the separate frame.

The embodiment of FIG. 3, which also shows the upper part of the window sash 16 with seals 17 and 18, which, of course, should not be interrupted during continuous ventilation in accordance with the invention, differs from the image in FIG. 1 and 2 essentially in that instead of a ventilating profile 10 extending over the entire width of the window, a nozzle fan 10 ', commercially available shortened in comparison with the window width, is used, the suction pipe 19 of which, usually ending freely around the profile of the split frame at the upper end, is included in the prechamber 5 of the upper cross member. Performing with suction holes 9 in the lower cross member of a separate frame in the embodiment of FIG. 3 is the same as in FIG. 1 and 2.
