Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: design a self-contained unit that separates with window, it comprises blower fan and supports the support body of blower fan, support body is arranged in the cavity of body of wall, on support body, be provided with air inlet and air outlet, between air inlet and body of wall one side, be provided with arc sound absorption deflector, between air outlet and body of wall opposite side, also be provided with arc sound absorption deflector; And air inlet and air outlet dislocation are arranged.The noise elimination ventilator buries in body of wall, and facade and indoor usage space are not had influence, and is convenient to install; Air inlet and air outlet are arranged at the outside and the indoor of wall respectively, and two arc sound absorption deflectors also are to be in cornerwise position thus, thereby make blower fan place cavity form eddy current; Blower fan can positive and negatively move, and can guarantee that two-way ventilation is accomplished in requirement according to room air, and air quantity also can be regulated size as required.
As preferably, on described deflector, be provided with through hole, which is provided with sound-absorbing porous material; And in body of wall, press close to the metope both sides and also respectively be provided with one deck sound-absorbing porous material.Press close in sound-absorbing material on the deflector and the body of wall and form an arc cavity between the sound-absorbing material of metope, the noise elimination air channel of being made up of high-efficiency multiple sound-absorbing material, the deflector that is covered with sound-absorbing porous material and cavity not only can absorbing high-frequency sound, and the centering low-frequency noise also has good acoustically effective.
As preferably, the indoor of the deflector below air outlet is provided with dismountable front panel, which is provided with the switch panel of control blower fan; Described air outlet is provided with movable blinds.Switch panel is arranged on the indoor, and remote-controlled, allows the people be easy to control turning to of blower fan, also quantity-adjustable; The setting of blinds can make the noise elimination ventilator out of service, behind the blinds sealing air outlet, avoids indoor cold and hot amount loss, better noise insulation.
As preferably, be provided with rain cover in the outside of air inlet, rain cover is wedge shape; Described air inlet is provided with steel wire.This structure can play and prevent that rainwater, leaf, bird, winged insect etc. from entering, thereby prevents to influence the normal use of noise elimination ventilator.
As preferably, the maximum height of described blower fan place cavity with the diameter ratio of fan blade is: 1.5-3: 1.
As preferably, the outside of the deflector above air inlet is provided with supporting network, and the indoor of the deflector below air outlet also is provided with supporting network, is covered with on the supporting network and the metope identical materials.
As preferably, described support body is provided with shell outward.Enclosure is rough grid, makes things convenient for the noise elimination ventilator to whitewash with external wall, and rendering layer can be attached on the noise elimination Ventilator housing securely, is convenient to do the building exterior finish.
Therefore, the utlity model has two-layer sound-absorbing material, the setting of this structure makes acoustically effective better, not only can absorbing high-frequency sound, and the centering low-frequency noise also has good acoustically effective; And because the setting of arc deflector makes at the blower fan cavity and can form eddy current, the positive and negative operation of blower fan can guarantee that two-way ventilation is accomplished in requirement according to room air, and air quantity also can be regulated size as required.
Simultaneously, the utility model also have small and exquisite attractive in appearance, the installation site of outward appearance flexibly, dismounting advantage easy to maintenance.
