Description
Technical field
The present invention relates to blower fan technical field, specifically a kind of blower fan inlet air plenum sound insulation Rainproof louver window.
Background technology
Fan noise is a kind of characteristic properties of blower fan, and most of noise can only eliminate its impact on people's productive life by the mode installing noise damper or sound insulation additional.And the blower fan that some occasion uses, general airflow pressure is higher, and blower fan intrinsic noise is large, and the using and the reserved two parallel connections are outdoor to be arranged on building top, fan outlet adapter road, and fan inlet is free state.Eliminate the impact of fan noise, silencing means must be installed at air inlet.Traditional noise damper will reach good noise reduction, and general volume is comparatively large, and heavier-weight considers outdoor installation, and muffler inlet also needs to install rain cover.And assembling position limits by size and building load-bearing, traditional noise damper cannot meet installation requirement, if the noise damper of selection of small, cannot meet noise reduction again.
Through retrieval, CN202451013 discloses a kind of utility model patent of ventilating silencing window shade, this patent comprises housing frame, movable shutters, parallel four-bar structure, retaining mechanism, described movable shutters is located at outside housing frame, described parallel four-bar structure is located at the inside wall of housing frame and the folding of movable shutters described in connection control, described retaining mechanism is used for being located at described parallel four-bar structure and goes out, described parallel four-bar structure is for controlling the folding of described movable shutters, described retaining mechanism is used for the folding degree of fixing described movable shutters, described ventilation shutter comprises frame, louvre blade, described frame comprises side frame, top margin frame, boundary frame area, described louvre blade is the dihedral that Open Side Down, the lower groove of described top margin frame has the groove of a del, the upper surface of described boundary frame area is herringbone, described louvre blade and described top margin frame, louvre blade, boundary frame area is hollow structure, sound insulation is filled out in described hollow structure, damping material, described air inlet upper, lower wall panels is provided with bloop, its deficiency is: one is complex structure, cost of production is high, louvre blade due to movable shutters is the symmetrical dihedral that Open Side Down, when ventilating, it is movable louvre blade must to be arranged to, logical wind action could be realized, therefore, add parallel four-bar structure, and need to increase locking mechanism to control the folding degree of movable shutters, two is due to the inlet end blade of movable shutters and the wallboard of outlet side blade being all provided with sound-absorption hole, although energy sound-deadening and noise-reducing, but can not be rainproof, in the louvre blade in use easily making rainwater or snow-broth enter into hollow structure along sound-absorption hole and boundary frame area, by sound insulation, damping material soaks and makes sound insulation, damping material is ineffective, three is because sound insulation materials is not coated, in the process of blower ventilation, the operation vibrations of motor, sound insulation materials is easily caused to reveal from suction hole, and cause affecting sound insulation and noise reduction effect.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide that a kind of structure is simple, compact appearance, lightweight, resistance is little, sound insulation, rainproof, the sound insulation Rainproof louver window of noise reduction.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of sound insulation Rainproof louver window, comprise framework and blinds, parallel blinds is provided with in framework, described blinds is intersected by inlet end blinds and outlet side blinds to be formed by fixedly connecting, described blinds lumen loading has acoustical cotton, it is characterized in that described blinds two ends are fixedly connected with framework respectively, the height of described inlet end blinds is the half of outlet side blinds height, be beneficial to intercept partial noise and import surrounding environment into, acoustic reflection number of times not only can be made to increase and coincidence effect and increase absorption, and, air-flow is also made to pass through comparatively smoothly, thus reach high noise elimination, the requirement of low resistance loss, the periphery of described outlet side blinds is coated with porous plate, upper surface and the side of described inlet end blinds are coated with weather shield, lower surface is provided with lower porous plate, described weather shield upper end is fixedly connected with blinds upper surface, outlet side through transition arc surface, lower end is fixedly connected with lower porous plate through arc convex, be beneficial to prevent rainwater or snow-broth from entering in blinds along air intake, reach sound insulation, good muffling effect, the effect of ventilation long service life.
The present invention also can be coated with fiberglass fabric by the acoustical cotton external surface in blinds, is beneficial to prevent acoustical cotton from revealing, reaches the effect that long service life, sound-absorbing and soundproof effect are good.
The present invention, owing to adopting said structure, has that structure is simple, compact appearance, lightweight, resistance is little, sound insulation, rainproof, the advantages such as noise reduction.
