Problems solved by technology

[0003] At present, the existing windows are mainly in the form of aluminum alloy, plastic steel and a small amount of steel windows, wooden windows, etc. These types of windows have a common disadvantage: they can be naturally ventilated when the window is opened, but the effect of sound insulation is not achieved. Poor sound insulation and no natural ventilation

Embodiment 1

[0025] In the first kind of resonant ventilation and sound-absorbing window of the present invention, one end of the glass window 2 on the outside of the wall can be opened outwards, and the transparent sound-absorbing member 6 is a transparent micro-perforated plate 7 arranged on the glass window at the other end. The transparent micro-perforated plate 7 is inclined inwardly from the opening and is installed in the sound-absorbing cavity 5 and fixed on the end wall; the opposite end of the glass window 2 on the inner side of the wall and the outer glass window 2 can be opened inwardly, The transparent sound-absorbing member 6 is a transparent micro-perforated plate 7 arranged on the inner glass window at the other end, and the transparent micro-perforated plate 7 is installed in the sound-absorbing cavity 5 and fixed on the end wall inclined outward from the opening. . The glass windows on the inner side of the wall and the transparent micro-perforated plates on the outer gla...

Embodiment 2

[0027] The second type of acoustic brake type ventilation suction and sound insulation window according to the present invention, the glass window 2 on the outside of the wall is a bay window structure that can be opened on both sides, the glass window 2 on the inside of the wall is divided into three parts, and the glass in the middle part Window 2 can be opened inwardly. The transparent sound-absorbing member 6 is a transparent micro-perforated plate 7 arranged on the bay window glass. The transparent micro-perforated plate 7 is arranged inwardly from both sides of the bay window glass in the sound-absorbing cavity 5 and connected to the bay window glass. The middle forms a high point. In this embodiment, sound-absorbing and insulating bay windows are arranged outside the wall windows, sealed up and down, and a transparent resonant sound-absorbing cavity is installed inside. The top and bottom are equipped with transparent parallel sound-absorbing cavities, and the thicknes...

Embodiment 3

[0029] The third kind of sound brake type ventilation suction and sound insulation window of the present invention, the glass window 2 on the outside of the wall is a bay window structure that can be opened outwards on one side, and the glass window 2 on the inside of the wall is divided into three parts, which can be separated from the outside. The glass window 2 on the opposite side of the opened glass window 2 can be opened inwardly. Other structures are the same as in Embodiment 2.

[0030] In the present invention, the window frame adopts aluminum alloy or heat-insulating broken bridge profiles, and the profiles are all hollow cavity structures. The glass adopts double-layer laminated glass structure. A transparent micro-perforated plate resonant sound-absorbing structure is added on the inner side of the glass, in the form of an oblique cavity resonant structure. The profiles are sealed with sealing strips, and the contact between the window and the wall is fixed and sm...

Abstract

This invention discloses a venting noise insulation widow, which comprises a window frame fixed in the wall and a group of glass widow set in the frame, wherein the window frame including a garment frame set outside the wall and a core frame set inside the wall, and both the garment and core frame are set glass widow can be opened; between the garment and core glass widow forms the acoustic cavity, and a transparent acoustic element is arranged in it; the invention can be the sound lock mode and the resonant mode according to the requirement. Between the garment and core frame it can be set shade and heatproof curtain.

Description

1. Technical field [0001] The invention relates to a window in a commercial and residential building, in particular to a ventilation-absorbing and sound-insulating window that can reduce noise in a room and maintain ventilation. 2. Background technology [0002] With the rapid development of modern industry, transportation and urban construction, environmental noise pollution has become one of the biggest public hazards affecting the quality of life of residents at home and abroad. People living in noisy metropolises, on both sides of traffic roads, and in industrial areas are harmed by noise all day long, seriously affecting people's lives and physical and mental health. Due to the low living standard in the past, people didn't care much about noise, but with the improvement of people's living standard and the enhancement of self-protection awareness, environmental noise has become a problem of great concern to ordinary people, and having a quiet living environment is the c...
