Description

ventilation sound insulation window

technical field

The utility model relates to a sound-insulation window, in particular to a ventilation and sound-insulation window.

Background technique

At present, urban traffic noise has become the main cause of environmental pollution. Due to the complexity of traffic noise sources, it is very difficult to control, and in some aspects there are almost no effective solutions. Urban traffic noise includes noise generated by roads, railways, urban railways, airports, etc., and noise barriers can be used to control traffic noise. Barriers have a better effect on noise reduction for low-rise buildings, and the effect of buildings above six floors is poor. The most harmful noise is usually on the tenth floor. Most of the roads, railways, and urban railways in my country's large and medium-sized cities are high-rise buildings, and the sound insulation of barriers is generally 10-15dB. Therefore, the effect of using barriers to control traffic noise There are still some problems. It is a better method to control traffic noise with sound-proof windows, especially for road noise. However, Chinese people have the habit of opening windows to ventilate. The government invests in replacing soundproof windows for residents along the line in order to control noise. Residents still have the opinion that "opening the windows makes you noisy, and closing them makes you suffocate." In addition, although the proportion of railways and airports in the urban traffic noise control market is not large, the noise of railways and airports exceeds 80-90dB, and the noise energy is concentrated below the low frequency of 250Hz. have very serious effects.

Contents of the invention

In view of the above problems, the purpose of this utility model is to provide a ventilation and sound insulation window which not only has sound insulation but also ventilation, and has the function of dust reduction.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a ventilation and sound insulation window, which includes two window frames installed in the same window opening, and divides each window frame into upper and lower parts. The inner and outer double-layer glass windows installed between the window frame and the center sill are characterized in that it also includes a first noise reduction channel, which is arranged at the bottom of the two window frames, and the first noise reduction channel The air inlet of the sound channel is arranged horizontally on the outdoor side, and the air outlet is arranged horizontally and upwardly between the two window frames. The air inlet is provided with an openable sealing block, and the air inlet and outlet are separated by The sound-absorbing partition is divided into a rotating sound-absorbing channel; a second sound-absorbing channel is sealed and connected between the middle poles of the two window frames, and the air inlet of the second sound-absorbing channel is horizontally arranged at the bottom , the air outlet is arranged horizontally on the top, and the air inlet and outlet are separated by a sound-absorbing partition to form a return sound-absorbing passage; the outer glass window, wherein the upper part of the upper part is a fixed window glass, and the lower part of the middle part is a glass shutter ; The inner glass window, wherein the upper part of the upper part is a glass shutter, and the lower part of the middle part is two inward opening casement windows.

The sound-absorbing baffles and the sound-absorbing channels are made of steel plates, powdered quartz plates and glass wool sound-absorbing materials.

A rainproof cover is arranged on the top of the sealing block.

Mutually sealed soft sealing strips are arranged between the glass louvers.

The soft sealing strip includes a fixed part connected with glass louvers and a cantilever part used for sealing, which are formed by co-extrusion of soft and hard PVC materials.

The sealing block is connected to the casing of the first noise reduction channel through a hinge and a magnetic sealing strip.

A drawer for ash discharge is provided at the bottom of the first muffler channel.

Because the utility model adopts the above technical scheme, it has the following advantages: 1. Since two mufflers are provided at the bottom and the middle of the double-layer window, the muffler can pass through the bottom of the window without opening the outdoor window. The fresh air enters the air inlet of the channel, and after a period of silencing, it passes through the silencing channel in the middle for a second stage of silencing, and then enters the room, thus realizing the utility model purpose of not only being able to ventilate, but also having high sound insulation. After testing, this kind of use state of the utility model can achieve the effect of sound insulation of 35 decibels, reaching the effect of three-level sound insulation windows. 2. The utility model solves the low-frequency resonance trough phenomenon existing in ordinary insulating glass, which is the weakest frequency section in the sound insulation of ordinary sound-insulating windows. The utility model increases the sound insulation of the low-frequency resonance trough frequency section by 15dB, and reaches More than 30dB, which will have a significant effect on the control of railway and airport noise. 3. The utility model utilizes the position setting of the two noise-absorbing channels and the setting of the sound-absorbing material in the noise-absorbing channel, which not only effectively attenuates the noise under the action of the sound-absorbing material, but also makes the coarse dust in the air flow Effective landing in collision and volume change, thus playing the role of dust removal. 4. The utility model is equipped with a dust-collecting drawer in the first silencing channel at the bottom, so the dust can be cleaned conveniently; and the second silencing channel corresponding to the middle part is set at the lower part and the outlet at the upper part, so It can be cleaned by back blowing of air flow or vacuum cleaner, and the accumulated dust can be easily removed. 5. The utility model uses glass louvers in the inner and outer glass windows, and installs soft sealing strips on the glass louvers. When the glass louvers are closed, it not only has a good light transmission effect, but also has a particularly good sealing effect. At the same time, the glass It is divided into thin strips, which increases the damping characteristics and improves the sound insulation performance; after testing, the utility model can achieve a sound insulation effect of 44 decibels in a fully enclosed use state, basically reaching the upper limit of the sound insulation of existing sound insulation windows . 6. The utility model hides the second noise-absorbing channel between the center poles of the window, which not only does not affect the appearance of the window, but also does not expose it to the outside, and has a long service life. 7. The utility model is equipped with a sealing block installed through a hinge and a magnetic sealing strip at the entrance of the first noise-eliminating channel, and a rainproof cover, so that the only part exposed to the outdoors is well protected, and the horizontal setting The unique rain cover and sealing block add a concave-convex plane to the whole building, which are neatly arranged under each glass window, and the appearance is very beautiful. 8. The sound insulation and absorption material used in the utility model and the setting position of the material fully consider the sound insulation and absorption effect, and the installation and production are also very convenient. The utility model can be widely used in various buildings, especially in buildings with relatively high requirements on the sound insulation effect. The utility model applies the acoustic technology to the door and window manufacturing industry, solves the contradiction between ventilation and sound insulation, makes it reach 35dB in the semi-ventilated state, 44dB in the closed state, and the ventilation area reaches more than 600cm ² .
