Embodiment 1

[0036] On the basis of the above embodiments, the air inlet 3 and the air outlet 9 are provided with useful filter screens and protective screens, which can purify the air while preventing animals from entering the ventilation duct and affecting the use of the equipment.

Embodiment 2

[0038] In the direction from the air inlet 3 to the air outlet 9, there are fan 20, high-frequency sound-absorbing cavity 13, and low-frequency sound-absorbing cavity 13 in sequence. The low-frequency sound-absorbing chamber 13 is set at the last position. The low-frequency sound-absorbing chamber 13 can reduce the low-frequency noise of the fan 20 while eliminating the low-frequency noise of the external environment. Noise from the system into the room. The rotating shaft of blower fan 20 is connected with motor 21, and the connection point that fan 20, motor 21 links to each other with fixed frame is all provided with damping device, just can reduce vibration and sound.

Embodiment 3

[0040] On the basis of the basic implementation, the air inlet 3 is provided with a self-closing baffle, the self-closing baffle includes a sound insulation baffle, the sound insulation baffle is movably connected to the base plate 1 through a hinge, the base plate 1 is provided with a driving device, and the driving device The drive end of the drive unit is dynamically connected to the sound insulation baffle through a transmission mechanism; the drive device includes a drive motor, and the drive motor is electrically connected to the main control platform through a cable. A sealing rubber pad is provided at the joint where the sound insulation baffle and the air inlet 3 meet, further reducing the noise introduced into the room and saving energy.

[0041] When the room does not need to be ventilated, the main control platform controls the movement of the drive motor, and then drives the sound insulation baffle through the driving device to match the sound insulation baffle wit...

Abstract

The invention discloses a ventilation and sound insulation window, which comprises a window, an active noise reduction ventilator is arranged on the window, the active noise reduction ventilator includes a ventilation channel, and a high frequency noise reduction device and a low frequency noise reduction device are arranged on the ventilation channel , the ventilation channel is provided with a fan for increasing the air circulation rate; the low-frequency muffler device includes a low-frequency muffler chamber, and a sound wave generator is arranged on the low-frequency muffler chamber. It can achieve large-flow ventilation in the room and at the same time reduce the noise introduced from the external environment; especially the low-frequency noise less than 300Hz that is not easy to attenuate and has strong penetrability can be effectively controlled to reduce low-frequency radiation noise; when the window is closed, the window as a whole The sound insulation is 35‑40dB, reaching the level 4 sound insulation performance of building doors and windows (GB/T8485‑2000).

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...
