Description

Technical area

The The invention relates to a forced ventilated window with frame, sash, a center seal, a receiving groove for holding the center seal, a stop surface, at the center seal to form a room-side and a weather-side seaming chamber sealingly applied, and a device for limiting the air flow from the weather-side seaming chamber in the room-side folding chamber, as well as a device for limiting the airflow of a forced air Window.

Of the Use of thermally insulated windows with improved joint tightness often results, especially in use in wet rooms like baths and kitchens, to increased moisture damage like mold infestation, unless a regular and adequate ventilation of the Rooms ensured can be. A similar Problem occurs in apartments with open gas heating o. The like. On. It has therefore been variously suggested windows with a forced ventilation equip that independently from a manipulation by the residents a minimum ventilation of the Ensures rooms. At higher Air pressure differences between interior and building exterior due to high wind speeds to lead such forced ventilation but too undesirable high volume flows the exchanged air, which causes a high energy loss and possibly Cause drafts.

State of the art

There are already many proposals for forced ventilation windows have been made, which provide a limitation of the air flow at higher pressure differences. The DE 196 10 428 C2 relates to a generic forced-ventilated window with frame, sash and a center seal. The seal has a first sealing lip, the upper end rests with the window closed to a contact surface of the frame or sash. In this first sealing lip are air passage openings. The seal further has a second sealing lip, which is elastically, with the window closed freely movable and arranged at an acute angle to the first sealing lip, that at a certain differential pressure between the outside of the window opposite the inside of the window, the air passage openings at least partially closed become. This solution has proven very successful in practice, however, the seal must be made with very high precision in order to achieve a reproducible closing characteristic of the seal. In addition, this construction is not suitable to close the air passage openings already at relatively low air pressure differences.

The DE 199 29 133 C2 relates to a wing and frame plastic window having a window fold between an outer frame seal and an inner wing seal, wherein air flows between the wing and the frame from outside to inside and vice versa through the window fold. At least one folding ventilator is provided in the window fold, which has an air guiding chamber and a volume flow limiter. The folding fan is attached to the frame. The actual ventilation path and the flow limiter are not accessible from the outside, so they can not be cleaned without much effort. In addition, the construction is relatively expensive.

task

task The present invention is therefore a generic forced ventilation window with flow limitation and a device for limiting the airflow of a forced air Window available to provide that do not have these disadvantages. Further tasks and concerns of the invention will become apparent from the advantages of the teaching of the invention across from the known solutions.

Presentation of the invention

The Invention solves this task by a forced ventilation window according to claim 1 or a device for limiting the air flow according to claim 2, preferably in conjunction with one or more of the features the dependent claims.

The inventive device for limiting the air flow has a main body and a pendulum in it stored flap on. The main body has means for latching fastening in the receiving groove of the forced-ventilated window, which also serves to accommodate the center seal. In the place, at the device of the invention for limiting the air flow in the center seal receiving groove is engaged, while the center seal is recessed. The Air limitation device according to the invention and the center seal thus form together with the center seal stop surface circumferential separation of the folding chamber in a room-side and a weather-side folding chamber.

The axis of rotation of the pendulum-mounted flap is preferably shifted relative to the stop surface of the central seal in the direction of the weather-side folding chamber in the idle state, so that the pendulum-mounted flap in the idle state corresponding ventilation gap of 2 to 8 mm releases. When a predetermined by this distance air pressure difference between the weather-side and room-side folding chamber, the pendulum-mounted flap is brought to the center seal stop surface to concern, whereby the air supply is largely stopped.

Prefers is the pressure difference at which the pendulum-mounted flap limits the volume flow, between 20 and 60 Pascal, in particular between 25 and 45 Pascal.

Around to prevent the pendulum mounted flap when closing the casement Sheared or damaged in any other way is after a particular preferred embodiment the invention provides that the main body stop cam for limiting having the deflection movement of the oscillatingly mounted flap.

To a further preferred embodiment the invention has the pendulum-mounted flap in the stop area, that is, in the region with which the flap bears sealingly against the center seal stop surface, one or more areas of soft elastic material as a stop cushioning. The soft elastic region can be the entire length of the Include flap, it can but also small pimples o. The like. Made of soft elastic Material to be inserted into the flap, these nubs just to survive a few tenths of a millimeter. As a result, a deterioration of the sealing effect is prevented on the one hand, on the other hand reliable a rattle sound when Hitting the flap prevents.

The Receiving groove for holding the center seal can - as is common practice - in the frame profile be arranged, with the stop surface for the center seal regularly part of the sash profile is. However, it is within the scope of the present invention possible, the center seal in a center seal receiving groove of the sash provide and the stop surface form the center seal accordingly on the frame profile.

Appropriately points the forced ventilation window according to the invention in addition to the center seal still an inner stop seal and / or an outer stop seal on, wherein the inner and the outer stop seal in some areas by a closed casement not on the frame fitting Kederdichtung can be replaced. The air duct to the However, inside the room can also - as generally known - by a chamber of the sash guided become. Also regarding the air supply in the weather-compensating chamber corresponding solutions are possible.

Short description of the drawing

The Invention will be described below with reference to an embodiment and the drawing explained in more detail. It show:

1 a cross section through an inventive window in the idle state

2 a cross section like 1 , but with closed ventilation flap

3 a perspective view of the window frame with two ventilation devices

4 a perspective view of the device according to the invention

Best way to carry out the invention

In 4 is the ventilation device according to the invention 5 shown in perspective view. The main body 6 has the in 4 illustrated resting feet 10 as well as two lateral boundaries 11 on. The pendulum-mounted flap 7 indicates storage in the main body 6 on both sides the pins 8th on that in corresponding holes 9 the lateral limits 11 of the basic body 6 are rotatably mounted.

The operation of the ventilation device according to the invention 5 is determined by the in 1 and 2 illustrated cross sections through an inventive forced-ventilated window explained in more detail. In 1 is the ventilation device 5 while at rest, so shown at low air movement. The air initially flows from the weather side into the weather-compensated seam chamber 19 one. In the entire circumferential fold area is the weather-side folding chamber 19 through the center seal 12 ( 3 ) from the room-side folding chamber 20 sealed. Only in the upper horizontal area are - as in 3 illustrated - two juxtaposed ventilation devices 5 . 5 ' provided, which at this point the middle seal 12 quasi replace and with the resting feet 10 in the center seal receiving groove 13 are attached.

At low differences in air pressure between weather compensating chamber 19 and room-side folding chamber 20 hangs the pendulum-mounted flap 7 approximately vertically downwards and is about 4.5 mm to the center seal stop surface 14 ( 1 ) complains, so that the Luftführungsweg 21 from the weather-side folding chamber 19 over the room-side folding chamber 20 into the room interior is free. At an overpressure of more than 35 Pascals in the weather-compensated seam chamber 19 opposite the room-side folding chamber 20 will de flap 7 automatically by the air pressure difference to the middle Dich tung stop surface 14 Pressed and closes the air flow path 21 ,

To avoid rattling, the flap points 7 two slightly protruding areas - the stop dampers 18 - Made of soft elastic material. In the illustrated embodiment, the ventilation device 5 made of rigid PVC by injection molding, the stop damper 18 are molded from soft PVC.

In 2 and 4 are the stop cams 17 to recognize. These stop cams 17 prevent too much deflection of the flap 7 in the direction of the room-side folding chamber 20 to prevent the flap 7 when closing the window from the upper edge of the chamber 15 can be sheared off.
