Sound insulation ventilating window

Abstract

The invention discloses a sound insulation ventilating window. The sound insulation ventilating window comprises an external window (2) with an air inlet (1), an internal window (4) with an air outlet (3), and a muffling cavity body (5) which is positioned between the internal window (4) and the external window (2), and connected with the external window (2) and the internal window (4); louver muffling sheets (6) controlled by a motor are suspended inside the muffling cavity body (5); and the louver muffling sheets (6) are rotated or gathered under the action of the motor. The sound insulation ventilating window can stop low frequency band noises of which the frequency is lower than 500Hz so as to further weaken the noises from the outside of the window to the inside of the window; meanwhile, the ventilating performance of the sound insulation ventilating window can be guaranteed; the daylighting effect of the sound insulation ventilating window is better, the requirements of indoor noise reduction, heat insulation and daylighting of people can be met, and the structure is simple.

Description

technical field [0001] The invention belongs to the field of building doors and windows, and in particular relates to a sound-insulating ventilation window. Background technique [0002] With the development of urbanization, industrial and traffic noise has become a major factor affecting people's normal life and health. In order to solve this problem, people have made many efforts and invented various forms of sound insulation and ventilation windows. Among them, the most important is the combination of ventilated window profiles and sound-insulating glass, such as laminated glass, insulating glass and vacuum glass. Although the sound insulation can reach more than 30dB(A), it cannot block the sound below 500Hz. The noise in the low-frequency band, and the most important noise frequency band that affects people's normal life and health is concentrated below 500Hz, and the window made of the combination of ventilation window profiles and sound-proof glass cannot meet the req...
