Abstract

The utility model relates to a draught soundproof window and belongs to the field of construction door and window. The utility model comprises a two-track sliding window and a sound-absorbing apparatus (3). The sliding window is provided with hollow glass in different thickness. Structure of the sliding window and other parts of the utility model are similar to normal windows. The sound-absorbing apparatus (3) is positioned in a window opening (6) between the two-track windows, wherein cavity and the sound-absorbing apparatus (3) is capable of reducing noise, opening window sash (1),(5) to k (opening angle of the window sash), m (opening angle of the window sash) according to need to reduce noise and air renewal, adjusting opening angle of k and m to modify effect of draught and noise reduction, keeping distance between two window frames (2), (4) large as possible to enhance effect of soundproof. The two-track window is capable of reducing noise effectively, and simultaneously guarantee draught, and has simple structure, low cost nearly equal to normal window, applicable for new building windows and also for rebuilding windows.

Description

A kind of ventilation soundproof window

Technical field

The utility model relates to a kind of ventilation soundproof window, belongs to the building doors and windows field.

Background technology

At present, traditional window soundproof effect is undesirable, many ventilation soundproof windows newly developed, though soundproof effect is well, and complex structure, manufacturing cost height.In addition, just can not ventilation when traditional window is closed, window and can not the barrier noise.Install blower fan or air-conditioning on the wall additional, though can play the effect of ventilation, the expense height, to expend the energy, maintenance cost high and maintenance is inconvenient, and blower fan and air-conditioning itself have noise, influences people's work and rest.Though the soundproof window of somebody's exploitation also can be accomplished ventilation under the situation that does not expend the energy, complex structure, the manufacturing cost height, and the ventilation amount is little.

Summary of the invention

In order to overcome above defective and deficiency, the utility model provides a kind of ventilation soundproof window, and its structure is very simple, and manufacturing cost approaches general window, and soundproof effect is also good.Can also ventilation when reducing noise, purify air.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of ventilation soundproof window is made of twice sliding sash and sound arrester.The glass of sliding sash adopts hollow glass, and the thickness of glass is inequality.The structure of sliding sash and other parts are identical with common window, so that reduce cost and convenient the popularization and old window transformation.In the window opening mouth between the twice sliding sash sound arrester is installed, sound arrester forms in the window opening mouth around shape (total length of sound arrester equals to build the girth of window opening mouth, and denumerable section is spliced).The sound arrester inner core is that (composition is the oil fiber to the environment friendly acoustical absorption cotton, sound-absorbing effect is good, nontoxic, environmental protection is renewable, insect protected, protection against the tide, fire prevention) or glass wool, outside for approaching perforated plate (material available metal, plastics etc.), the bottom is thin plate (material available metal, plastics etc.).On the sound arrester that opens and closes part near sash, install purifier additional, in this purifier active carbon is housed, can filter out airborne dust, impurity, peculiar smell and pernicious gas, deleterious particle in the inlet chamber.During use, the per pass window is only opened a sash, and direction is opposite, forms staggered (specifically seeing Fig. 1).Air and noise enter the cavity that forms between the twice window from the opening part of the first road window, are positioned at the opening part inlet chamber of opposite side again from the second road window.Noise is subjected to stopping of twice window and sound arrester and wall in such cavity, will constantly change direction.According to the reactive muffling principle, noise will be subjected to reflection, resonance, stack and interference when passing through such cavity, make it to be decayed, and reaches the noise elimination purpose, and this method is mainly used in the elimination low frequency noise.In addition, noise according to the resistance noise reduction principle, will be subjected to the environment friendly acoustical absorption cotton in the sound arrester or the absorption of glass wool by such cavity the time, reach the noise elimination purpose, and this method is mainly used in eliminates the medium-high frequency noise.The distance h that strengthens between the twice window can improve low frequency sound insulation; Distance h is big more, and noise reduction effect is good more.The extended distance k, the m that window are big more, and noise reduction effect is poor more, and ventilation effect is corresponding also good more.When h, m were zero, window stopped ventilation, but noise reduction effect the best.

The beneficial effects of the utility model are: can effectively reduce noise, can also ventilation when reducing noise, purify air, and structure is very simple, and manufacturing cost approaches general window.Not only be applicable to newly-built window, also be applicable to the reconstruction window.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a principle schematic of the present utility model.

Fig. 2 is a sound arrester cross sectional view of the present utility model.

Fig. 3 is a sound arrester vertical view of the present utility model.

1. sash among the figure, 2. window frame, 3. sound arrester, 4. window frame, 5. sash, 6. building window opening mouth, k. the sash of the first road window and the distance between window frame (being extended distance), h. the spacing of twice window frame, the sash of the m. second road window and the distance between window frame (being extended distance), 11. environment friendly acoustical absorption cotton or glass wools, 12. thin Pierced Aluminum Plank, 13. thin aluminum sheet, the total length of a. sound arrester (equal to build the girth of window opening mouth, denumerable section is spliced).

The specific embodiment

In Fig. 1, Fig. 2, the glass of sash adopts the hollow glass towards inert gas, and the thickness of layer glass is respectively 4mm, 5mm, and hollow layer is 12mm.The twice sliding sash is installed in building window opening mouth (6), sound arrester (3) is installed in the window opening mouth between the twice sliding sash.Sound arrester (3) inner core is environment friendly acoustical absorption cotton (11), and the outside is the thin Pierced Aluminum Plank (12) of thickness 0.7mm, and the bottom is the thin aluminum sheet (13) of thickness 1mm.The width of sound arrester (3) is 50mm, and height H also is 50mm, and the length of installation base is 15mm, and available nailing or expansion bolt are fixed on sound arrester (3) in the window opening mouth.Open sash (1), (5) as required respectively to k (extended distance), m (extended distance), air and noise enter the cavity that forms between the twice window from the opening part (extended distance is k) of the first road window, are positioned at opening part (extended distance the is m) inlet chamber of opposite side again from the second road window.Noise is subjected to stopping of twice window and sound arrester and wall in such cavity, will constantly change direction, makes it to be decayed, and reaches the noise elimination purpose.In addition, noise will be subjected to the absorption of the environment friendly acoustical absorption cotton (11) in the sound arrester when passing through such cavity, reach the noise elimination purpose.The big I of k, m is opened as required or is closed sash and regulate arbitrarily; But k, m are big more, and noise reduction effect is poor more, and ventilation effect is corresponding also good more.When h, m were zero, window stopped ventilation, but noise reduction effect the best.Distance h between twice window window frame (2), (4) can be big as far as possible according to the degree of depth of window opening mouth, and h is big more, and noise reduction effect is good more.
