Description

Field of the Technology

[0001] Air ventilation, recovery systems, making connections to or in air ventilation hoses

State of the Art

[0002] Currently, the air ventilation is becoming more and more popular also in new-build family houses. Whether it is air conditioning systems, recovery systems or controlled active air exchange. In current practice, the emphasis is primarily put on a trouble-free operation of air ventilation systems and also on the simplicity and the speed of its installation.

[0003] In partitions or in drop ceilings, the air ventilation system is distributed by air ventilation hoses, and in the interior, it is ended with an exit opening usually fitted with a mushroom valve, which enables the air flow from the air ventilation system into the room. The exit opening is situated in the interspace behind the curtain wall or in the drop ceiling. The exit openings into walls or ceilings are not fixed, they only passively hold due to the insertion of an intermediate piece between the exit opening and the mushroom valve. This unsecured connection can increase the susceptibility to failure of the system, when frequent handling the mushroom valve or its opening and closing for the regulation of the passing air can result in minor shocks leading to the exit opening falling out of the wall, and thus to the system failure. In a standard way, the air ventilation exit opening is fixed in the drop ceiling using clamps holding the exit opening body or an air ventilation hose, which is very inconvenient for the most common installation into plasterboard, since an aperture must be cut into the plasterboard for the exit opening, to which an interior valve is fitted, and the exit opening itself is not fixed, and its installation to the valve is difficult and requires sealing.

Description of the Invention

[0004] The air ventilation exit opening according to this invention disposes of a fixing rim for rear fixing the air ventilation exit opening directly into the partition, i.e. into its unexposed side, which is a wall or a drop ceiling, made usually of plasterboard or drop ceiling panels, thus eliminating anchoring to the ceiling or the wall behind this partition when looking from the interior. The exit opening is provided with a hose and a partition end cylindrical parts which are connected by the exit opening body, wherein a fixing rim is situated between the exit opening body and the partition end cylindrical part. Using the partition end cylindrical part, the exit opening is inserted into the aperture in the partition and onto which an interior, preferably mushroom, valve is fitted. The partition end cylindrical part of the exit opening is inserted into the aperture in the partition from the non-interior side and from the other exposed interior side of the partition, an interior valve closing the whole air ventilation distribution and connecting the air ventilation piping with the interior is fitted. The exit opening is fixed to the partition by screwing from the non-interior side of the building partition through an interior valve collar through the partition into the fixing rim of the exit opening. This way, the whole air ventilation exit opening is well fixed and removable.

[0005] The exit opening has two end pieces, a hose end cylindrical part for connecting the air ventilation hose, and a partition end cylindrical part for inserting into the aperture in the building partition and fitting the interior valve. These two end parts preferably have a different diameter. The inner diameter of the hose end cylindrical part for connecting the air ventilation hose is greater than the outer diameter of the air ventilation hose, preferably at most by 3 mm greater, to ensure a good connection between the air ventilation hose and the exit opening. The connection between the hose end cylindrical part and the air ventilation hose is usually sealed by a sealing to minimize the gas leaks in the connection. The partition end cylindrical part for fitting the interior valve, or its diameter, is variable and corresponds to the selected interior valve for which it is produced.

[0006] The fixing rim is preferably compact and is situated all around the exit opening at the edge between the exit opening body and the partition end cylindrical part of the exit opening for fitting the interior valve, which facilitates the fixation of the exit opening in the partition - after the installation into the partition, the fixing rim is situated either from the interior exposed side of the partition and/or it is situated from the rear side of the partition or the drop ceiling, i.e. most frequently the plasterboard. In both cases, the fixing rim is fixed to the partition using simple screwing a screw. Then, the interior valve is fitted directly into the exit opening or via an intermediate piece. This interior valve covers the exit opening and its fixing screws, and forms the exposed component of the whole air ventilation system.

[0007] The fixing rim has an annular ring, wherein the inner circle has a diameter equal to the outer diameter of the partition end cylindrical part of the exit opening and it directly fits tightly to it, and the distance between the outer circle and the inner circle is 0.7 to 4 mm; the rim is offset from the edge of the end part of the exit opening by 0.5 to 4 cm with thickness of 0.15 to 0.8 cm and is made of plastic. This ensures that the rim can be screwed through by screws and at the same time, the rim is not too wide to make the installation difficult. The rim thickness is of importance especially for high-quality fastening of screws to prevent screwing into the rim edge and to provide a tight connection.

[0008] With respect to the fact that the rim is made as a part of the exit opening, which is usually plastic, the rim is also plastic, mostly made of polypropylene, polyurethane, ABS or polystyrene. The rim can be made of metal as well, e.g. aluminium or thin-walled steel, and can be pressed into the plastic exit opening. In such cases, screws designed for metal must be used.
