SU1337505A1 - Noise-protected ventilation window - Google Patents

Description

The invention relates to the construction, in particular to the construction of windows with enhanced heat and sound protection characteristics.

The purpose of the invention is to increase the noise-shielding properties of the window in the ventilation mode and the thermophysical properties in the closed position, as well as ease of operation.

The invention is illustrated in the drawings.

Fig. 1 shows a sound insulating ventilation window, general view; in fig. 2 is a section A-A in FIG. one; on fig.Z - section bb in fig. one.

The noise-protective ventilation window contains box I, on which outer 3 and inner 4 bindings are fixed by means of hinges 2, and the middle binder 5 is fixed on the inner cover 4 in its upper part by hinges 6. In the middle part of the outer cover 3 there is a louvre grille 7, closed the entrance slit and the slots of the middle 5 and the inner 4 bindings are equipped with flaps 8 and 9 reinforced by means of hinges 10. The width of the middle binder 5 is smaller than the inner size of the box 1, resulting in side gaps 11, than in the closed position, the middle 5 and outer 3 bindings have sealing pads around each other 12. In the open position, the middle binding 5 is sealed in the upper and lower parts with an internal binding 4 by gaskets 13. The vertical bars 14 of box I have sound-absorbing plates 15 .

Research Institute bind 5 in the open position forms two labyrinth channels 16 of variable cross section.

The noise ventilation window operates as follows.

In the closed position, the middle cover 5 is pressed with gaskets 2 to the outside cover 3 along the entire perimeter, and valves 8 and 9 are closed. In this state, the window has heat and sound insulation characteristics corresponding to the best domestic and foreign triple glazed windows. In order to organize the ventilation of the room, while maintaining sound insulation, it is necessary to open valve 9 of the inner cover 4 and move the middle cover 5 against the stop with the internal cover 4, while the specified covers in the upper and lower parts are packed with gaskets 13. In this state, the air flow moves through the labyrinth the channel b in the direction indicated by the arrows, and the sound energy is effectively reduced both by moving along the labyrinth channel 16 and by absorbing the plates 15, which are perpendicular to the direction sound propagation through the labyrinth channel; 16. At the same time, due to the variable cross-section of the channels along the vertical, the flow of air from the street will be more active at the bottom of the window, and the entry into the room will be from above. To more efficiently ventilate the room, as well as to clean the louver 7, it is necessary to open valves 8 and 9.
