Abstract
The utility model relates to a sound insulation ventilation window, composed of a ventilating fan, an elbowed muffler, a glass window, a screen window and a louver. The sound insulation ventilation window can generate greater sound insulating effect through the sealing stripe of a double-layer or a single layer glass window, simultaneously, the ventilating fan can keep the circulation of the fresh air of the room, and the lighting effect is excellent. The sound insulation ventilation window mainly solves the problem that a building near a street is influenced by the traffic noise, and keeps the ventilation and the aeration of the room.
Description
The utility model relates to a kind of sound insulation vent window, and this window can reduce outdoor noise to indoor influence, simultaneously can also holding chamber in the circulation of fresh air.
Traffic noise accounts for more than 50% in urban environment noise pollutes, in the building of main line of communication both sides, be subjected to impact of traffic noise serious, particularly indoor when needing ventilation to window, outdoor noise is even more serious to indoor influence, therefore, reduces traffic noise to the influence in the building of main line of communication both sides, the circulation of the interior fresh air of holding chamber again just becomes the problem that people pay close attention to simultaneously.The overlooking noise of external at present solution mainly contains two kinds of methods to indoor influence, a kind of method is to take to seal window to solve the sound insulation problem, and the device that installs an air-conditioner solves the room ventilation problem, and this method is unsuitable for China's national situation, because China's power shortage, air-conditioner at short notice can not large-scale promotion.Another kind method is that Europe patent (patent No. ET87486) proposes, and it also is to take to seal window to solve the sound insulation problem, and ventilation stack is set in window frame, and the upper and lower side of window is provided with the turnover ventilation opening respectively, solves ventilating problem, this complex structure, cost height.Present domestic transport solution noise does not also have ripe way to indoor influence, the patent No. provides a kind of micro silencer ventilation louvre for 87210249 patent, and this louvre can reduce room noise, can also keep the indoor natural ventilating ventilation, but sound insulation factor is low, and daylighting is also not ideal enough.
The purpose of this utility model provides a kind of sound insulation vent window, and it can produce bigger defening effect, adopts the circulation of mechanical ventilation for indoor maintenance fresh air simultaneously, and good daylighting effect can also be arranged.
Sound insulation vent window provided by the utility model is made up of ventilation fan (1), elbow sound absorber (2), glass window (3) and (4), screen window (5) and louvre (6), as shown in the figure.The end face and the ventilation fan of elbow sound absorber are installed in the same vertical plane, and the bending direction and the sound source position of elbow are anti-phase, and angle of bend is 0～90 °, is advisable with 90 °.Glass window can be double-deck, promptly at original glass window (3), at this moment should add weather strip to improve sound insulation factor.The other end of window screening, louvre and elbow sound absorber is installed in same horizontal level, also can be not at same horizontal level and other positions in window frame.The louver sheet of louvre is generally movable adjustable, and its inclination angle is 0～180 °, also can make fixed.
Above-mentioned sound insulation vent window relies on double window or layer glass window to add weather strip sound insulation, reduces the noise that noise in the ventilation opening inlet chamber and ventilation fan produce with the elbow sound absorber.This structure defening effect is remarkable, when ventilation fan does not turn round, sound insulation factor can reach 27～28 decibels (A), and when ventilation fan turned round, sound insulation factor can reach 15～20 decibels (A), in addition, but by fresh air enough in the ventilation fan supply chamber, this sound proof window can provide good daylighting effect simultaneously, and summer can be heat insulation, can be incubated winter, also can reduce in the dust inlet chamber.
Description of drawings: Fig. 1 is sound insulation vent window elevation, and Fig. 2 is sound insulation vent window vertical view, and Fig. 3 is sound insulation vent window lateral view.1-ventilation fan among the figure, 2-elbow sound absorber, the original glass window in 3-room, the new glass window of installing in 4-Indoor sill edge, 5-air-vent window screening, 6-louvre, 7-wall.
Embodiment.
Sound insulation vent window window opening is of a size of: wide 1800mm, high 1500mm, the windowsill outer rim is installed a door frame steel sash in bare glass window indoor, thickness of glass is 3mm, in the sash of steel sash middle and upper part, adorn an elbow sound absorber (seeing accompanying drawing), angle of bend is 90 °, elbow sound absorber total length is 650mm, width is identical with the width and the height dimension of middle and upper part sash with height, ventilation fan is in the outermost end of elbow sound absorber, air-vent screen window and movable louvre are at the indoor end of elbow sound absorber, and the three (sees accompanying drawing) in same horizontal plane.The switch of ventilation fan and louvre is all indoor.Through noise testing, when ventilation fan did not leave, traffic noise can drop to 42～43 decibels (A) by 70 decibels (A), and sound insulation factor reaches 27～28 decibels (A); When ventilation fan turned round, noise can drop to 49～50 decibels (A) by 65～69 decibels (A), if use low-noise scavenger fan, room noise can further reduce.The ventilation volume of ventilation fan is 4.5m
3/ min can fully satisfy hygienic requirements (2.52m
3/ min) required ventilation volume.This sound insulation vent window can be opened or close according to user's needs, is applicable to residential houses at the front, also is applicable to the industrial plant factory building.
Claims (3)
1, a kind of sound insulation vent window, comprise ventilation fan (1), elbow sound absorber (2), glass window (3) and (4), screen window (5), louvre (6), the bending direction and the sound source position that it is characterized in that the elbow sound absorber are anti-phase, and angle of bend is in 0～90 degree scope.
2, sound insulation vent window according to claim 1 is characterized in that glass window can adopt double-layer glass, also can adopt single-glass to add weather strip, and glass window can be fixed, also can be openable.
3, sound insulation vent window according to claim 1 is characterized in that screen window, louvre and elbow sound absorber can be connected in same horizontal level, also can disconnect, or be installed on the diverse location of window frame; The louver sheet of louvre can be made into movable adjustable, also can be made into fixingly, and its inclination angle is in 0～180 degree scope.
