Abstract
A super-thin environmental protection ventilated noise elimination window comprises a window frame and two layers glasses of internal and external arranged on the window frame, which is characterized in that at least one first level noise elimination device and one second noise elimination device are arranged between the two layers glasses, the first level noise elimination device is embedded in a noise elimination chamber between the two layer glasses, one plane of the noise elimination chamber closed to the external layer glass is equipped with a wind inlet, one plane of the noise elimination chamber far from the window frame is equipped with a wind outlet and the lower portion of the wind outlet is equipped with a manger. The second noise elimination device comprises a noise elimination chamber and a cascade glass arranged on the external layer glass, a wind outlet of the noise elimination chamber is located at one side of the internal glass and a wind inlet of the noise elimination chamber is located at a position closed to the cascade glass. The noise elimination window has a thickness of about 9 centimeters and is capable of being replaced without need to change the prior window frame structure and meanwhile distinctively reduces noise. The noise elimination chamber is appended with noise reflex arc and averagely reduces noise to 25 decibels, furthermore, has excellent properties of light transmittance and ventilation.
Description
Technical field
The utility model relates to ventilation noise elimination window, particularly a kind of ultrathin environmental protection ventilation noise elimination window.
Background technology
Continuous increase along with city automobile, car noise has become a kind of new environomental pollution source, more and more influence people's dwelling environment, environment-friendly type ventilation noise elimination window arises at the historic moment, but, present ventilation noise elimination window is because the defective in the design, cause that anti-acoustic capability is poor, sluggish in air circulation, defective such as daylighting difference and outward appearance are bad, for example the patent No. is 89220934.8 design employing elbow type sound insulation aeration technology, this scheme is stretched out the building outside because of elbow part, not only influence the outward appearance of building, and cause the hidden danger of falling object from high altitude.
Summary of the invention
In view of the above-mentioned deficiency of prior art, it is a kind of aesthetic in appearance that the utility model provides, the ultrathin environmental protection ventilation noise elimination window that daylighting, sound insulation and performance of ventilating are good.
This ultrathin environmental protection ventilation noise elimination window comprises window frame and is installed on inside and outside layer glass on the window frame, it is characterized in that: between layer glass (15,16), be provided with at least one one-level silencing apparatus and a secondary silencing apparatus, described one-level silencing apparatus is positioned at nearly window frame (14) and locates, the one-level silencing apparatus contains the sound attenuation room (2) that is embedded between the layer glass, sound attenuation room (2) sets into air port (1) near the one side of glass outer (16), sound attenuation room (2) sets out the air port away from the one side of window frame, and the bottom of air outlet is provided with watertight shutter (7); Described secondary silencing apparatus comprises sound attenuation room (5) and is arranged at laminated glass (6) on the glass outer (16), and the air outlet of sound attenuation room (5) is positioned at inner layer glass (15) one sides, and the air intake of sound attenuation room (5) is positioned at nearly laminated glass (6) and locates.
The characteristics of this ultrathin environmental protection ventilation noise elimination window are:
1, good looking appearance, and thick 9cm that has an appointment of window, it is just replaceable must not change original window frame structure.
2, noise reduction is obvious, is added with the sound attenuation room of noise reflex arc, 25 decibels of noise reduction average out tos;
3, printing opacity, perspective, ventilation, the unbalanced contradiction of noise reduction have been solved.
Description of drawings
Fig. 1 is the stereogram of an exemplary embodiments of the present utility model;
Fig. 2 is the sectional drawing of Fig. 1 embodiment;
Fig. 3 is the front view of its second embodiment;
Fig. 4 is the sectional view of Fig. 3.
The specific embodiment
Further specify below in conjunction with accompanying drawing.
The embodiment one of this ultrathin environmental protection ventilation noise elimination window as shown in Figure 1 and Figure 2.It comprises: window frame 14, and be installed on inside and outside layer glass 15,16 on the window frame, between layer glass, be provided with two one-level silencing apparatus and a secondary silencing apparatus, two one-level silencing apparatus lay respectively at the window frame place on left and right both sides, and the secondary silencing apparatus is between two one-level silencing apparatus.The one-level silencing apparatus contains the sound attenuation room 2 that is embedded between the layer glass, and the one side of 2 outer layers of glass of sound attenuation room 16 sets into air port 1, and sound attenuation room 2 sets out the air port away from the one side of window frame, and the bottom of air outlet is provided with watertight shutter 7, is used for preventing that rainwater from flowing into.The secondary silencing apparatus comprises sound attenuation room 5 and the laminated glass 6 that is installed on the glass outer 16, and the air outlet of sound attenuation room 5 is positioned at inner layer glass 15 1 sides, and the air intake of sound attenuation room 5 is positioned at nearly laminated glass 6 places.
The sound attenuation room 2 of the described one-level silencing apparatus of present embodiment is surrounded by polylith abatvoix 4, its integral body is hollow rectangular shape, side in the face of air intake vent 1 in the sound attenuation room 2 can be installed noise reflex arc 3, when sound wave arrives the noise reflex arc, be reflected outside the exit window according to the sound wave of reflection theorem about 1/3, remaining sound wave is after abatvoix 4 is further subdued, and by the space of inside and outside two-layer sound control glass, the air outlet that enters secondary sound attenuation room 5 is in the air inlet chamber.Described sound attenuation room 2 also can be hollow cylinder shape or other shape.With reference to Fig. 2, the sound attenuation room 5 of its secondary silencing apparatus is the isosceles triangle arrangement by three blocks of abatvoixs and constitutes.Constitute between the above-mentioned abatvoix and internal and external layers of glass of sound attenuation room, can adopt transparent adhesive tape, double faced adhesive tape bonding between the abatvoix, or connect by fastener.
Fig. 3, Fig. 4 are embodiment two structure charts.Embodiment two is basic identical with embodiment one structure, and both main distinctions are:
1, embodiment two installs vertical louvres window formula anechoic sheet 11 or horizontal venetian blind type anechoic sheet 12 between one-level silencing apparatus and secondary silencing apparatus, and anechoic sheet 11 and anechoic sheet 12 are made by abatvoix, is applicable to that outdoor noise is on average greater than 70 decibels environment.
2, among the embodiment two, in the sound attenuation room 2 of one-level silencing apparatus noise reflex arc 3 is not installed.The structure of sound attenuation room 2 is slightly different with embodiment one in addition.
