Description

Technical area

The invention relates to a compulsorily ventilated window or door designed as a central sealing system comprising a frame made of frame profiles, a folding area extending between frame and sash, a center seal which separates the folding area into a weather-side and a room-side folding area, wherein the Air duct through the weather-side and the room-side folding area is carried out, and means for autonomously limiting the amount of air at a defined pressure difference between the weather-side and the room-side fold region, wherein the frame profiles and / or the sash profiles have at least one hollow chamber, which via a wall to the weather side and adjacent the room-side fold area.

The use of heat-insulated windows with improved joint tightness often leads, especially when used in damp rooms such as bathrooms and kitchens, to increased moisture damage such as mold infestation, unless regular and adequate ventilation of the rooms can be ensured. It is therefore known to provide windows with a forced ventilation, which ensures a minimum ventilation of the rooms. In order to avoid undesirable high volume flows of the exchanged air and associated draft phenomena at higher differences in air pressure between the interior and building exterior due to high wind speeds, means for autonomously limiting the amount of air are used when exceeding a defined pressure difference.

State of the art

From the DE 196 10 428 C2 is a generic forced-ventilated window with a center seal is known in which the air flow through a perforated center seal. In these systems, a reliable limitation of the air flow when exceeding a defined pressure difference between the weather-side and the room-side folding chamber, however, very difficult.

From the DE 202 21 802 U1 is a similar forced ventilated window with air flow restriction known in which closes after unclamping the center seal a pendulum mounted in a base flap when a defined air pressure difference is exceeded, the air path between the weather-side and the room-side folding chamber. However, such airflow limitations are not applicable to all central seal systems. In addition, these can be easily damaged by the free accessibility of the swinging flap.

From the DE 199 29 133 C2 an air flow limiting device for a center seal system is known, which also provides a pendulum-mounted flap that closes the vent path when a defined air pressure difference between the weather-side folding chamber and the room-side folding chamber, the fan flap is covered to the outside by a protective housing. This ventilation device is used in the folding area and is perceived by its large visible volume as aesthetically disturbing.

A similar approach follows the EP 1 837 477 B1 Here, the air flow through slots between the weather-side folding chamber and one of the steel reinforcement chamber of the frame upstream ventilation chamber on the one hand and corresponding slots between the room-side folding chamber and the ventilation chamber on the other hand. The air duct is at the EP 1 837 477 B1 deliberately passed through a ventilation chamber, which is sealed off from the steel chamber, in order to avoid condensation in the steel chamber. Such a construction is thus possible only in profile systems having a ventilation chamber upstream of the steel chamber.

task

Object of the present invention is to provide a forced-ventilated window with fan module and a fan module for this purpose, the high air exchange rates at low air pressure differences between the weather-side and the room-side folding chamber can be used, without interfering internals in the rebate and manages universally applicable for central sealing systems.

Presentation of the invention

The invention solves this problem by a forced-ventilated window with door according to claim 1, preferably with one or more of the features of the dependent claims 2 to 8, and by a fan module according to claim 9, preferably with one or more of the features of the dependent claim 10.

Core of the present invention is the use of a fan module, which is inserted into a corresponding opening of the falzseitig the steel reinforcement chamber bounding wall of the frame profile or the sash profile and opens a ventilation path between the weather-side hemming and the room-side seaming area with the fan door open. The air duct is thus not directly through the steel reinforcement chamber, but only by a fan module inserted into the steel reinforcement chamber.

According to a preferred embodiment of the invention, the opening of the folded side interrupts in the steel reinforcement chamber bounding wall of the frame profile or the sash profile at the same time also the central sealing plane, so that the fan module according to the invention can be used very easily. In order to close the center seal plane again, the fan module preferably has a continued center seal, which connects seamlessly to the center seal attached to the frame profile or to the sash profile.

According to a preferred embodiment of the invention, a ventilation flap is inserted in the fan module, which is deflected when a defined pressure difference between the weather-side seaming area and the room-side seaming area is exceeded, thereby closing the ventilation path through the fan module. Particularly preferred is the fan door alone by their Gravity in the rest position, ie with open ventilation path, pivoted. With increasing air flow - in accordance with an increasing air pressure difference between the weather-side folding area and the room-side rebate - in this preferred embodiment of the invention, the fan flap pivoted from its center of gravity and moved in the end of its pivoting movement against a stop bar on which the fan valve then sealingly abuts and thus the Ventilation path closes. Particularly preferably, the striking of the fan flap is damped at the stop bar, for example, by soft elastic materials to minimize impact noises.

In a particularly preferred embodiment of the invention, means are used which limit the pendulum deflection of the pendulum-mounted fan flap. Depending on requirements, for example, thereby the fan door forcibly be locked in an open position, forcibly in a closed position or in a central position. Conveniently, locking means are used, which engage in their end position or are secured in other ways against accidental adjustment.

In order to enable a simple installation and for maintenance purposes disassembly of the fan module according to the invention in or out of the opening of the wall of the hollow chamber, the fan module preferably comprises means for latching attachment.

The fan module according to the invention allows by relatively large if necessary volume even with smaller differences in air pressure between weather-side and raumseitigem fold area relatively high air exchange rates, without disturbing aesthetically in the rebate area between frame profile and casement profile. At the same time, condensate formation in the steel reinforcement chamber is reliably prevented by the closed design, without the need for special glazing or sash frames with separate ventilation chambers.

Best way to carry out the invention

In Fig. 1 is the upper horizontal portion of a forced ventilation window according to the invention with frame profile 1, sash profile 2, steel reinforcement 12 and inventive fan module 20 is shown. The folding area 13 between the frame profile 1 and sash profile 2 is bounded to the outside by the frame overlap 6 and the outer stop seal 7 and the interior of the room by the inner stop seal 8 and subdivided by the center seal 3 in a weather-side seaming area 14 and a room-side folding area 15. The center seal 3 is thereby inserted or extruded with its foot region into the center seal receiving groove 4 of the frame profile 1 in the PCE method ( Fig. 2 ) and is sealingly against the center seal stopper 5 of the sash profile 2. The air supply to the weather-side seaming area 14 is offset laterally - in Fig. 1 not shown - by an interruption of the outer stop seal 7. The connection between the room-side folding area 15 and the interior of the room is - as well known from the prior art - possibly also laterally offset either via a notch of the inner stop seal 8 or by a milling in the room-side rollover of the sash profile 2 (in Fig. 1 not shown).

The frame profile 1 has to stiffen a large hollow chamber 10 (steel reinforcement chamber) for receiving the steel reinforcement 12. The steel reinforcement 12 is - as known from the prior art - by means of corresponding screw 17 with the frame profile 1 shear-resistant connected ( Fig. 2 ). The casement profile (2) also has a corresponding steel reinforcement (in Fig. 1 not shown).

The fan module 20 according to the invention is in Fig. 4 shown in a spatial view in more detail. It consists of the fan housing 21 and the fan insert 22 (FIG. Fig. 5 ). The fan insert 22 in turn is composed of the fan cover 23, the fan flap 24 and the thumbwheel 32 and the axle pin 35 ( Fig. 9 ). The air guide takes place with open fan flap 24, starting from the weather-side seaming area 14 first via the entry slots 27 in the fan module 20, then through the gap between the fan valve 24 and stop bar 25 in the interior of the room facing the fan housing 21 and then through the outlet slots 28 in The fan-flap depends on lower air movement following the gravity approximately vertically downwards, as in Fig. 6 shown. When a defined amount of air is exceeded, the fan flap 24 moves counterclockwise until it stops at the stop bar 25 (FIG. Fig. 6 ) created and the ventilation path thereby at least largely shuts off.

The assembled fan module 20 becomes - as in FIGS. 2 and 3 shown - in an opening (cutout 9) of the wall 11 of the hollow chamber 10 (steel reinforcement chamber) clipped. For clipping serve the clips 29 of the fan cover 23 ( Fig. 5 ). As in particular in Fig. 3 shown, interrupts the cutout 9 also the center sealing region of the frame profile 1. The fan module 20 therefore has a continued center seal 31, which continues the contour of the interrupted center seal 3 and the center seal plane 16 closes again. The air can therefore not flow directly from the weather-side seaming region 14 into the room-side seaming region 15, but only through the fan module 20.

As in particular in Fig. 1 and 2 shown, the largest part of the fan module 20 is sunk in the hollow chamber 10 of the frame profile 1, so that it does not appear optically disturbing. In order to prevent moisture from penetrating into the hollow chamber 10, the fan housing 21 is designed to be at least largely dense and, for example, sealed by a molded soft elastic seal or a sealing compound against the wall 11 of the hollow chamber 10. The air guide is thus not directly through the steel reinforcement chamber 10, but only through the inserted into the steel reinforcement chamber 10 fan module 20th

In order to prevent ingress of insects into the fan module 20, the inlet slots 27 are arranged side by side in the illustrated example with a smaller distance. If necessary, however, the outlet slots 28 can be arranged correspondingly close to each other.

The fan module 20 shown in the figures has - according to the preferred embodiment of the invention - additional means limiting the pendulum deflection of the pendulum-mounted fan valve 24. For this purpose, a thumbwheel 32 is used, which can limit the pendulum movement of the fan valve 24 with a locking pin 33. The thumbwheel 32 is mounted on the pivot pin 35 itself pivotally, wherein the locking pin 33 - as in FIGS. 9 and 10 recognizable - engages through the guide slot 36 and projects into the pendulum region of the fan valve 24. In Fig. 1 . 7 and 8 the adjusting wheel 32 is rotated in the clockwise direction to the outermost position and secured in this position via small knobs 34 in the guide slot 36 against unintentional adjustment. In this position will the fan door 24 is pressed against the stop bar 25, so that the ventilation path is interrupted.

In Fig. 6 however, the thumbwheel 32 is rotated counterclockwise to the outermost position and secured in this position also via small nubs 34 in the guide slot 36 against unintentional adjustment. In this position of the adjusting wheel 32, the locking pin 33 is outside the pivoting range of the fan valve 24, so that at low air pressure differences between the weather-side seaming area 14 and the room-side seaming area 15 a corresponding ventilation can take place, said ventilation automatically at a defined pressure difference is exceeded by the fan valve 24 is closed.

In the FIGS. 9 and 10 the assembly of the fan module 20 according to the invention is explained in more detail: first, the setting wheel 32 is inserted with the locking pin 33 in the guide slot 36 and secured to the axle 35. The fan flap 24 is engaged in the guide grooves 26 of the both sides of the fan cover 23 arranged arms and the thus completed fan insert 22 inserted into the fan housing 21. Serve this purpose, the clips 30, which engage in corresponding recesses in the interior of the fan housing 21. The complete fan module 20 is in turn used with the aid of the front side of the fan housing 21 projecting clips 29 in the opening 9 of the wall 11 of the hollow chamber 10 of the frame profile 1. The clips 29 are shaped so that the entire fan module 20 at any time for maintenance or cleaning purposes from the opening 9 can be removed again.

The continued center seal 31 of the fan module 20 can, if necessary z. B. in two-component injection molding process integrally with the fan cover 23 or be subsequently inserted by inserting a short center seal piece in a groove 37 of the fan cover 23.
