Abstract

The present invention relates to a forcibly ventilated window, or door consisting of hollow-chambered profiled sections with a seal disposed between a blind frame (B) and a casement(F) and sealing outward, and a mechanism for supply of fresh air through the blind frame (B). Fresh air is supplied through the blind frame via at least one ventilating seal (VD) to the interior of the building, and a device arranged in the fresh-air current (L) and acting in dependence on wind pressure regulates amount of fresh air . At least one air-permeable element (T) being incorporated in the window's blind frame (B) front chamber (VK) and situated in the fresh-air current (L) path is provided with a structure that whirls air and/or restrict amount of air flowing inwards when a defined air pressure (p2) is exceeded. Said blind frame (B) is provided on its outer side with at least one aperture (01) and on its inner side with at least one another aperture (02).

Peculiarly ventilated window

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a forced vented window, door or the like of a hollow chamber profile rod with a seal between a window frame and a sash, sealed outwardly and provided with a fresh air inlet through the window frame. or similarly.

BACKGROUND OF THE INVENTION Forced ventilated windows, doors and similar structures are known. Fresh air is supplied either through a ribbed seal in the window flap or through channels in the window frames from outside to inside the building.

At higher wind speeds, or at air pressure differences of more than 50 Pa, undesirable whistling noises, drafts and the like may occur inside the building, adversely affecting indoor comfort.

In order to avoid such adverse effects, it has already been proposed to provide a channel in the upper frieze of a fixed window frame in which a mechanical self-acting flow restrictor is located. However, this limiter is expensive and wasteful. Further disadvantages of these devices have to be seen in the fact that the fresh air flowing into the building and having a lower temperature than the air in the room decreases downwards due to its higher density just outside the window and thus adversely affects the indoor comfort of the room. In order to overcome this disadvantage, it has been proposed to use a flap which diverts the inwardly flowing air upwards towards the ceiling, thereby at least partially causing a swirling flow. This solution to the problem is also unsatisfactory and entails additional costs.

SUMMARY OF THE INVENTION The object of the present invention is to overcome these drawbacks and to create a forced ventilation window in which all the disadvantages of known devices are eliminated, its ventilation device should be invisible, ensure adequate ventilation of the interior even when operating open furnaces such as stoves or fireplaces, stoves and likewise and also when using suction devices and air supply at higher wind speeds up to a predetermined value, for example, pressure differences greater than 50 Pa.

SUMMARY OF THE INVENTION

This object is achieved by a forced ventilated window according to the invention, characterized in that at least one turbulator is installed in the window frame of the window in the direction of the fresh air path from outside to inside to limit the air inlet when the specified air pressure is exceeded. This solution has a number of significant advantages due to the inclusion of at least one turbulator placed on or in the window frame, in particular to improve indoor air, effectively prevent mold, improve noise attenuation, and reliably prevent pollen, dust and the like from entering the interior of the building. In addition, it is possible to provide the required air volume at a predetermined amount of air to be exchanged and / or to use fans, for example, hoods.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a forced ventilation window; FIG. 2 is a cross-sectional view of another exemplary embodiment of a forced-ventilation window; and FIG. 3 is a cross-sectional view of another variant.

DETAILED DESCRIPTION OF THE INVENTION

The invention consists essentially of the known fixed window frame B, the sash frame F of hollow chamber profile bars, the inner reinforcement A, the window panes G and various seals. The door may be of substantially the same or similar construction, so that the description of the illustrated window embodiment also applies to similar doors and other constructions of this type.

VÓ. which all open into the outer hollow chamber HK? Between this outer hollow chamber HK and the window rebate FF there is another open hollow chamber VK, which is connected both to the outer hollow chamber HK and to the window rebate FF. The window rebate FF area is sealed outwardly by the seal D, while a ventilation seal VD is provided on the inside of the building to allow air to flow through the air vents V0 into the outer hollow chamber HK in the window frame B and the second open hollow chamber VK into the window rebate FF. In the path of this air stream L, a turbulator T is placed on the wall of the window frame B opposite the open hollow chamber VK. The turbulator T has a capillary or labyrinth structure and swirls the laminar air stream entering the window frame B. At the same time at higher pressure differentials above predetermined values, for example at an air pressure difference of more than 50 Pa, which is considered acceptable.

The variant of the embodiment according to FIG. 2 corresponds to the example of FIG. 1, but the turbulator is mounted in the hollow chamber VK.

Κ similar phenomena occur when the turbulator T is formed from a plurality of fine capillaries, possibly with a honeycomb structure, which also converts the initially laminar air stream L into a swirling flow, so that the flow resistance increases and draft and possibly other phenomena are associated with higher wind speeds; air flows are eliminated. It will be understood that other bodies with a labyrinth structure may be used for the turbulator T, and in addition, the turbulator T may be provided with replaceable dust protection filters FI and the like. This protection filter FI may be located, for example, upstream or downstream of the turbulator T.

While the seal D seals the window rebate FF outwardly, the ventilation seal VD is provided with the requisite number of transverse and / or longitudinal grooves or ribs and ensures the flow of air L from the window rebate FF into the interior of the building. Instead of this ventilation seal, it is also possible to use another air passage, which is located, for example, in the window frame B, as shown in FIG. 3.

Another exemplary alternative embodiment of the invention in Fig. 3 shows a window frame B in which a turbulator channel TK is formed. Into this turbulator channel TK is inserted turbulator T and possibly other replaceable protective filters FI. The turbulator channel TK is equipped with a swinging flap KL on its inner and outer outlet. which is opened or closed according to the direction of air flow.

The solution according to the invention is not limited to use in windows, doors, vents and the like. The modification of the frame according to the invention can also be used elsewhere in the building, for example with ventilation elements for improving the indoor climate in the building. *
