Abstract
The utility model discloses an environment friendly sound insulation ventilator containing a tank with an air feed port and an air drainage port, muffling channel and a centrifugal ventilator are arranged in the tank, the wind feed port, the muffling channel, the centrifugal ventilator and the wind drainage port are connective in sequence. The utility model not only ensures indoor ventilation quantity but also indoor noise, meanwhile, it will not impact on the normal lives of the users.
Description
Technical field
The utility model relates to a kind of sound insulation ventilator of environment-friendly type.
Background technology
No matter the window of installing with regard to existing structure is that the main function of timber window, steel sash, aluminum window, plastic-steel window is with regard to daylighting and ventilation.But because process of urbanization is more and more faster, the town dweller is subjected to the puzzlement of noise more and more.Seething traffic noise, the construction noise in construction site, the amusement noise of two family house on the street ... city symphony of forming like this make that the town dweller is restless by day and sleepless by night, the difficult peace of sleeping and eating, escape nowhere to follow.Noise invisible, colourless also tasteless is a kind of evil of sensation is being engulfed people just as the demon health.The incidence of disease of " noise sickness " grows with each passing day, even is regarded as a kind of new people's slow poison desperately that causes.Therefore, noise is known as the 3rd public hazards that are only second to atmosphere pollution by common people.The resident who is subjected to noise pollution in the city is in order to prevent in interference of noise.Use medi-empty glass window, it has reached a part of defening effect but the sound insulation that is difficult to reach the different kinds of building thing requires and lose the ventilation function of window.Long-time no fresh air replenishes, and causes new air pollution.People can cause bigger injury to healthy in crowded airless room, SARS in 2003 has just been beaten alarm bell to people.
In order to solve the ventilating problem of sash sound insulation.Successively have multiple patented technology to propose a plan, patent No. 89220934.8. utilizes elbow type sound insulation aeration technology! Be to have reached purpose on the function, but this scheme is stretched out building external because of elbow, the outward appearance of building is difficult to handle to promote the use of be restricted.
The patent No. 92239550.0 be utilize the window opening upper and lower part or about portion dislocation glass is installed, utilize the way of gravity-flow ventilation.The contradiction that also can solve sound insulation and ventilate is subjected to poor, the blast of indoor exogenous damp but solve the back rate of air circulation; And the ventilation angle waits until that the influence of factors vary is difficult to reach the standard of the rate of air circulation of country's " IAQ ", and particularly formula such as school, meeting room place is more inadequate.
Patent No. 99256002.0. adopts mechanical ventilator to add the way of double pane, though the louver problem of sound insulation and ventilating problem ventilator that solved is difficult to handle, when running into storm, rainwater enters bellows inside easily.In addition, inlet air, air draft are arranged in the same bellows, air intake vent is easy to generate short circuit like this, does not reach ventilation effect; In addition, double window is opened inconvenient, must have a window will be made as sliding window.
The utility model content
At the shortcoming of prior art, the sound insulation vent window that the purpose of this utility model provides a kind of good looking appearance, not only can insulate against sound but also can ventilate.
To achieve these goals, the technical solution of the utility model is: a kind of environment-friendly type sound insulation ventilator, comprise the casing with air inlet and exhaust outlet, be provided with noise elimination passage and centrifugal blower in described casing, described air inlet, noise elimination passage, centrifugal blower and exhaust outlet communicate successively.
Connect with vibration abatement between the inner bottom surface of described centrifugal blower and casing, this vibration abatement comprises a plurality of bolts that are with spring, the top and bottom of each bolt are equipped with rubber blanket, and the upper end of bolt connects with described centrifugal blower, and the lower end of bolt connects with the inner bottom surface of casing.
Described noise elimination passage comprises the sound absorber composition that a plurality of cross sections are identical, the longitudinal section is different.
Described noise elimination passage has two and lay respectively at two ends, the left and right sides in the casing, simultaneously two air inlet correspondences be opened in casing the indoor two ends, the left and right sides and communicate with the noise elimination passage respectively.
The housing of described casing is formed by U type aluminium and sound insulationg board.
Described air inlet and exhaust outlet are provided with the decoration louver outward.
Described interior is provided with one deck sound-absorbing material.
Compared with prior art, the utility model had both guaranteed indoor ventilation volume, had reduced indoor noise again and people's normal life was not impacted.

The specific embodiment
See also Fig. 1 to Fig. 9, the environment-friendly type sound insulation ventilator of present embodiment, comprise the casing 3 with air inlet 1 and exhaust outlet 2, be provided with three-dimensional noise elimination passage 4 and centrifugal blower 5 in casing 3, air inlet 1, three-dimensional noise elimination passage 4, centrifugal blower 5 and exhaust outlet 2 communicate successively.Connect with vibration abatement 6 between the inner bottom surface of centrifugal blower 5 and casing 3, this vibration abatement 6 comprises a plurality of bolts 8 that are with spring 7, the top and bottom of each bolt are equipped with rubber blanket 9, the upper end of bolt 8 connects with described centrifugal blower by spring pad 13, and the lower end of bolt 8 connects with the inner bottom surface of casing.Three-dimensional noise elimination passage 4 has two and lay respectively at two ends, the left and right sides in the casing 3, simultaneously two air inlet correspondences be opened in casing the indoor two ends, the left and right sides and communicate with the noise elimination passage respectively.The housing 10 of casing is formed by U type aluminium and sound insulationg board.Air inlet and exhaust outlet are provided with outward decorates louver 11.Interior is provided with one deck sound-absorbing material 12.
Environment-friendly type sound insulation ventilator is installed in the top of the window opening of building, indoor ventilation is mainly undertaken by centrifugal blower, when the centrifugal blower in the environment-friendly type sound insulation ventilator starts just directly to outdoor air draft, when exhaust air rate begins to certain the time, the indoor negative pressure that just forms, outdoor air in crack between a door and its frame by the window opposite and the window seam inlet chamber and keep balance, thereby has formed the system of an indoor air convection under the effect of negative pressure.Sound insulation process in the environment-friendly type sound insulation ventilator mainly is the sound-absorbing material in the case, three-dimensional noise elimination ventilating duct and against shock device are implemented, sound-absorbing material be fire-retardant and acoustic absorptivity greater than 0.7 cone, with the solid passage of eliminating the noise, increase mobile distance of the air of air in case and resistance, to reach the purpose of noise reduction.Adopt the against shock device, avoided centrifugal blower vibrations to casing in running to produce, reduce noisiness.
After adopting the utility model, indoor noise figure reaches the noise criteria of all kinds of common building things below 40dBA.
