Ventilation noise-insulation window

Abstract

The invention discloses a ventilation noise-insulation window comprising a window body. A noise-reduction ventilation device is arranged on a window body and comprises a channel communicating with theoutdoor space and the indoor space; an air purifying device, a fan for driving air to flow, a low-frequency silencer for eliminating low-frequency noise and a high-frequency silencer for eliminatinghigh-frequency noise are arranged on the channel; the air purifying device, the high-frequency silencer, the low-frequency silencer and the fan are connected one by one through pipelines to form an air passage; and the high-frequency silencer is arranged in front of the low-frequency silencer in the air flowing direction. Noise, especially the low-frequency radiation noise, transmitted from the outside environment can be lowered while large-flow ventilation of a room is achieved; when the window is closed, the overall noise-insulation amount of the window is 35-40 dB; and air in the room can be purified, and environment information is displayed through a display screen.

Description

technical field [0001] The invention relates to the field of energy-saving and environment-friendly equipment, in particular to a ventilation and sound insulation window. Background technique [0002] Noise pollution, air pollution, and water pollution are listed as the three major pollution sources in the city. With the rapid development of my country's economy, the construction of high-level transportation infrastructure such as expressways and high-speed railways is also getting faster and faster, and more and more people live beside the busy traffic roads. Traffic noise nuisance has become a prominent environmental problem in the 21st century, seriously affecting people's work, study and life. [0003] At present, it is a better way to control construction noise with sound-proof windows, especially for traffic noise. However, people's habit of opening windows for ventilation will lead to a direct decline in the sound insulation performance of sound-proof windows. Alth...
