Description
Technical field:
The utility model relates to a kind of structure of window, particularly a kind ofly has natural ventilation, and isolates or reduce the window arrangement of noise.
Background technology:
At present, the kind of the structure and material of all kinds of windows of people's inhabitation and workplace is a lot, and the form of unlatching is also different.Traditional windowing mainly is ventilation, but thing followed problem is an outdoor noise also in the inlet chamber, influences people's living and working environment.If close window air lock external noise, but lost ventilation function simultaneously.Reduce noise, the mode with airtight or double-deck hollow window achieves the goal usually.Therefore, under the state of natural ventilation, can isolate as far as possible and reduce noise is the fine target that modern people seek assiduously.
Utility model patent ZL98249482.3 " noise reduction window " discloses a kind of ventilation noise reduction window, but, its windage is bigger, noise reduction is provided with certain limitation, and the structure that it adopts whole window to protrude outside wall, in many urban architectures, be restricted, can not on the basis of existing window, reequip.Utility model patent ZL01242822.1 " natural ventilation noise reduction window " discloses the noise reduction window of another kind of form, but its muffler part is embedded in opaque article of formation in the sash.Though can play the noise reduction effect, misfit with the traditional architectural aesthetics, a kind of sense of discomfort is visually arranged.The same situation that has an opaque article in sash of utility model patent ZL02226342.x " natural ventilation noise reduction window " causes visual discomfort.
Summary of the invention:
The purpose of this utility model be for provide a kind of simple in structure, elegant in appearance, install and the equal natural ventilation window for noise elimination very easily of repacking.
The technical solution of the utility model is achieved in that natural ventilation window for noise elimination, form by double window fan structure 1 and single window fan structure 2 two parts, it is characterized in that: described double window fan structure 1 comprises towards outdoor exterior window 11 with towards indoor interior window 12, at double window fan structure 1 and the single window fan structure 2 middle sound absorbers 3 that are provided with, described sound absorber 3 is made up of air vent 31, acoustical cotton 32 and microperforated panel 33, air vent 31 evenly is arranged on the gas channel, in microperforated panel 33 is housed, and be lined with acoustical cotton 32.
Described double window fan structure 1 can be arranged above and below with single window fan structure 2.
Described double window fan structure 1 and single window fan structure 2 also can about arrange.
The inside of described air vent 31 is provided with the bending angle.
The inner and outer shell of described sound absorber 3 and microperforated panel 33 are made the back plastic-blasting by galvanized sheet metal.Technological merit of the present utility model is:
1. do not protrude outside the body of wall, can not violate the building regulations in some cities.
2. applied widely, all very convenient to newly-built or existing window installation repacking.
3. simple in structure, with aluminum window ease of connection, convenience are installed.
4. sound absorber adopts galvanized steel plain sheet to make, and the appearance plastic-blasting is antirust corrosion-resistant, long service life.
5. be equipped with perforated percentage in the sound absorber around the gas channel and be about 2% microperforated panel, sound absorbent of inner liner, tool good sound absorption decrease of noise functions.
6. material source is extensive, and cost is relatively low, the actual promotional value of tool.
7. the requirement of natural ventilation can be satisfied, the purpose of sound insulation and noise reducing can be reached again.
8. specious.Need not embed an opaque section in the sash, meet the traditional architecture aesthetic requirement.
9. need not energy consumption.
10. be specially adapted to places such as near the dwelling house of elevated road, the main line of communication, lively fairground or industrial enterprise, office, hospital, school.Can improve people's living environment quality effectively.

The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is specifically described, the utility model is made of double window fan structure 1, single window fan structure 2 and sound absorber 3.Sound absorber 3 places between double window fan structure 1 and the single window fan structure 2, and described double window fan structure 1 can be arranged above and below with single window fan structure 2, referring to Fig. 1, also can about arrange, referring to Fig. 2.Described double window fan structure 1 is formed ventilating sound-proof denoising structure system, and by forming towards the outdoor exterior window of opening 11 with towards indoor interior window 12 2 parts of opening, these two parts form a multi-direction controlled airway.Described sound absorber 3 is made up of air vent 31, acoustical cotton 32 and microperforated panel 33, air vent 31 evenly is arranged on the gas channel, in perforated percentage is housed is about 2% microperforated panel 33, and be lined with acoustical cotton 32, the inside of air vent 31 is provided with the bending angle, can improve acoustically effective like this, and its inner and outer shell and microperforated panel 33 are made the back plastic-blasting by galvanized sheet metal, play antirust corrosion-resistant, the effect of long service life.
Double window fan structure 1, formation can be controlled the gas channel of rate of air circulation or switching.Form double-deck sound proof window during contract fully, full open forms transom window.Over window 11, inside the Pass during window 12, the air that contains noise is flowed through behind the double window fan structure 1, direction changes, noise energy is at first tentatively decayed.Flow through again behind the air vent 31 of sound absorber 3, also absorbed simultaneously and decay, reached the optimum state of natural ventilation noise reduction, referring to Fig. 3 by microperforated panel 33 and acoustical cotton 32 around the sound absorber 3.In like manner, top and the bottom or about part all can make multi-form combination setting.
The utility model is tested result of use of the present utility model through Minhang District Environmental Monitoring one station, Shanghai City after Minhang District building, Shanghai City is installed and used, and the result is as follows:
| Sequence number | Point position | Noise source | Measured value Leq dB (A) | |
| 1 | 1 meter outside window | Traffic noise | 68.7 | |
| 2 | Indoor | Traffic noise | 55.1 | The standard- |
| 3 | Indoor | Traffic noise | 40.8 | The complete shut-down window |
| 4 | Indoor | Traffic noise | 45.8 | (over window, inside the Pass window) ventilating sound-proof state |
Conclusion
According to the on-the-spot test result as can be seen, the utility model is effectively to the control traffic noise to the influence of dwelling environment, can reach standard of environmental noise of urban area GB3096-93.In each side such as natural ventilation and isolation, reduction noises, result of use is good, is a kind of natural ventilation window for noise elimination with extensive promotional value.
