Abstract
The utility model discloses a noise insulation ventilator comprising shells of an air inlet and an air outlet set on both sides, a sound absorbable layer disposed on the inside of shell, a fan disposed on the air outlet inside the shell and some clapboards alternatively and intervably disposed on the upper cantilever of the shell between the air inlet and the air outlet, inwhich said clapboards are double-layer micropore plates with empty cavities. The utility model has the advantages of a good noise-proof effect, can be associatedly used in the door and the window or exterior walls made by any materials no matter what thickness.
Description
Technical field
The utility model relates to a kind of ventilator, particularly a kind ofly can will effectively intercept the ventilator of external noise.
Background technology
At present, constantly spread the urban area, and the traffic major trunk roads extend in all direction, and viaduct, expressway and quick main line star sieve gather, and add that car enters speeding up of family, and the flow motor on the highway sharply increases progressively.The noise that automobile and road surface friction produce and the blare of automobile engine become a kind of insufferable urban environment noise and pollute, and force the resident family of major trunk roads both sides to close door and window all day, replenish but indoor air is changed.In order to address the above problem, some to have occurred and can intercept the ventilator of noise.A kind of ventilator is for example arranged, comprise the housing that has air inlet and air outlet, be provided with blower fan in the housing, in order to reach the purpose every noise, the sidewall in the housing is provided with the parallel staggered dividing plate of cantilever, and has all laid sound absorbing layer on whole outer inwall of housing and the dividing plate.Said structure has played the purpose that intercepts noise to a certain extent, but also there is following defective: because the material of sound absorbing layer common foaming sponge, asbestos, mineral wool or the clamping plate of adopting are made more, so inflammable, easily adsorb dust, of long duration perishable rotten, cause new pollution; In addition, the restriction of said structure also is limited for the obstruct of outside noise; The problem that also has the ventilation deficiency simultaneously.
The utility model content
The utility model is the defective that overcomes prior art, provides a kind of good every noise effects, easy care cleaning and the big ventilator of ventilation.
In order to achieve the above object, it is a kind of every the noise ventilator that the utility model provides, comprise that both sides are provided with the housing of air inlet and air outlet, the housing madial wall is provided with sound absorbing layer, the air outlet place is provided with blower fan in the housing, housing opposing sidewalls upper cantilever between air inlet and the air outlet is staggered to be interval with some dividing plates, and wherein, described dividing plate is the double-deck microwell plate that has cavity.Adopt said structure, form mazy air channel in housing, the dividing plate that has the double-deck microwell plate formation of cavity intercepts noise, absorb effectively.
The diameter of the micropore on the described dividing plate is the 0.1-0.3 millimeter.
The area summation of micropore accounts for the 20-30% of top plate area on the top plate of described dividing plate, and the area summation of micropore accounts for the 5-15% of lower plywood area on the lower plywood.
The top plate of described dividing plate and the distance between the lower plywood are the 6-15 millimeter.
Described housing is the double-decker that has cavity.
Described housing is the fixing branch body structure of plug-in mounting.
Described housing and dividing plate are made of aluminium alloy plate.
Described sound absorbing layer is flame-retardant expanded sponge or foamed plastics.
Described air outlet and air inlet are provided with aluminium alloy and decorate blinds.
Described blower fan has the antivibration mounting that is made of four pyramid type rubber feet.
Advantage of the present utility model is, good every anti noise, dividing plate by staggered spaced and parallel setting in the housing, and dividing plate made the in addition double-deck microwell plate structure of cavity, and housing also adopts double-decker, inwall is provided with sound absorbing layer, can make indoor noise≤40 decibel (during machine operation) effectively with the isolation of noise.
Because housing of the present utility model and dividing plate all adopt aluminium alloy plate to make, thus pollution-free, safe and reliable, only clean the air inlet blinds and get final product.
Because the utility model adopts special fan, exhaust air rate is big, adopts the small, dedicated blower fan of 10W, exhaust air rate 〉=280m
3/ h.
Simple in structure, easily to make, cost is low, can be applicable.
Applied widely.The utility model can be made various sizes according to different occasions, can with the door and window or the supporting use of outer body of wall of any material and thickness.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is explained in detail.
As depicted in figs. 1 and 2, Fig. 1 provides a kind of outside drawing every the noise ventilator for the utility model, and Fig. 2 is the cross-sectional view of the utility model under user mode.Being installed between the body of wall 7 of square every the noise ventilator, housing 1 is for having the double-decker of cavity, and its both sides are provided with air inlet 5 and air outlet 6, and air outlet and air inlet place are provided with aluminium alloy and decorate blinds, are beneficial to sound insulation and are easy to clean.Housing 1 madial wall is provided with sound absorbing layer, and sound absorbing layer is flame-retardant expanded sponge in this example, also can adopt the sound-absorbing material of porous such as foamed plastics.Air outlet 6 places are provided with blower fan 4 in the housing 1, and blower fan 4 can adopt the small, dedicated blower fan of 10W, and exhaust air rate is reached 〉=280m
3/ h upgrades indoor air as early as possible.Housing opposing sidewalls upper cantilever between air inlet and the air outlet interlocks and is interval with some dividing plates 2, form mazy air channel, and dividing plate 2 is for having the double-deck microwell plate of cavity, the diameter of the micropore on the dividing plate is the 0.1-0.3 millimeter, the area summation of micropore accounts for the 20-30% of top plate area on the top plate of described dividing plate, and the area summation of micropore accounts for the 5-15% of lower plywood area on the lower plywood.The top plate of described dividing plate and the distance between the lower plywood are the 6-15 millimeter.The diameter of micropore is 0.2 millimeter in this example, the gross area sum of all micropores accounts for 25% of the top plate gross area on the top plate of dividing plate, the gross area sum of all micropores accounts for 10% of the lower plywood gross area on the lower plywood of dividing plate, distance between the upper and lower laminate is 10 millimeters, and this moment, the effect of dividing plate noise reduction was best.Because it is indoor that noise must could arrive through the passage of S shape, acoustic resistance is big, has played certain soundproof effect, passes through the noise reduction of dividing plate simultaneously again, and the sound absorbing layer absorption of noise on the box wall, makes soundproof effect reach optimum degree.
In order to eliminate the noise of ventilator self, blower fan has the antivibration mounting that is made of four pyramid type rubber feet.
For the ease of safeguarding cleaning, described housing can be the fixing branch body structure of plug-in mounting, and the mode of plug-in mounting can be projection and groove assembling mode etc. as shown in Figure 2.Housing 1 and dividing plate 2 all are to be made of aluminium alloy plate simultaneously, and be pollution-free, easily cleans long service life.
