Abstract
The utility model relates to a low-noise silencing ventilator whose box is a box-type structure, an exhaust fan is arranged on one side of the four side walls, a tuyere is arranged on the opposite side thereof, and the inside of the box is provided with a transverse barrier forming a labyrinthine passageway. Acoustic material is laid on the inner of the box, so the silencing effect is good. The exhaust fan uses the pumpdown running, so the self-body noise of the silencing ventilator is low. Compared with the condition of windowing when the single window is closed, the noise can be decreased by 12-15 db by using the ventilator, compared with the condition of windowing when the double window is closed, the noise can be decreased by 18-20 db, and the machine self-noise is less than 35 db.
Description
The utility model relates to ventilation unit
Dwelling house is subjected to the interference of traffic noise deeply along the street, and outdoor noise is to pass into indoor by the window on the exterior wall, opens the window, and just has noise to import into, closes window, and the hermetyic window seam, and it is indoor just to stop that noise imports into.As single window is made into double window then noise jamming will reduce greatly.But having sealed the window room just can't ventilate.To solve room ventilation and can adopt two kinds of ways at present closing under the situation of window, the one, the device that installs an air-conditioner, the 2nd, ventilating fan is installed.The device that installs an air-conditioner in a large number costs an arm and a leg, and expends a large amount of electric energy, is not suitable for the present national conditions of China, and air-conditioner is less in order to reduce its ventilation volume of power consumption, can not satisfy the requirement of ventilation fully, and machine itself also produces noise.Though install that the ventilating fan price is lower, little power consumption, ventilation volume is big but the very big outdoor noise of the noise of machine itself also can pass through can not reduce indoor noise jamming in the inlet chamber of ventilating fan hole.
The purpose of this utility model is that design a kind of machine noise own is lower and can stop the ventilator that outdoor noise is entered the room.
Formation of the present utility model is: this noise elimination ventilator is a case structure, one side in the sidewall of four sides is installed ventilating fan, and its relative one side is opened the air port, and horizontal obstruct is set in the casing, form tortuous labyrinth passage, external noise can not be led directly to import into indoor.Laterally intercepting is a fan-shaped column.Sound-absorbing material is all laid in cabinet wall and horizontal obstruct, reflects and diffraction in casing to reduce sound wave, so just can obtain bigger sound deadening capacity on short length, thereby reduce box sizes.But the maze-type structure gas-flow resistance is big, when air velocity is high, air-flow regeneration noise is bigger, the horizontal obstruct of this structure is taked fan-shaped to reduce resistance, reduce the ventilating fan rotating speed simultaneously,, reduced the air-flow regenerated noise to lower air velocity, levy sound deadening capacity when big thereby protect, self-noise is very low.
Illustrate that accompanying drawing is as follows:
Fig. 1 is the structural representation (top plan view) of the utility model noise elimination ventilator
Fig. 2 is the structure vertical section schematic diagram of the utility model noise elimination ventilator
Accompanying drawings embodiment is as follows:
The utility model noise elimination ventilator (see figure 1) is made casing (1) with sheet metal, family expenses ventilating fans (2) are installed on a sidewall, on its relative sidewall, offer ventilating opening and installation activity louver (5), the mosquito net (6) of setting up defences in the inboard of ventilating opening, the inwall of whole box body (four sidewalls and top, the end) all lays sound-absorbing material (3), horizontal obstruct (8) is set in the middle of casing, laterally intercepting (8) is a fan-shaped column, on, contact with the top and the bottom of casing down, laterally intercept the labyrinth passage that in casing, forms complications, to strengthen the noise elimination effect.Laterally the surface that intercepts is provided with aluminium expanded sheets (7), laterally intercepts inner filling sucting sound material (4), and sound-absorbing material can be used foamed plastics.
Be to reduce air velocity the motor speed of family expenses ventilating fan is descended, its concrete measure is to reduce supply voltage, and general family expenses ventilating fan is by the 220V mains supply, existing with auto-transformer with 220V voltage reduce to 125V, 110V, 95V three retainings are selected for use as required.Because the specified ventilation of general family expenses ventilating fan is bigger, so its ventilation still can satisfy the room air-conditioning requirement when step-down is used.Auto-transformer can be placed in box house, also can be placed in the outer suitable place of case.
The utility model noise elimination ventilator can reach ventilation＞200M/ hour, adopts summer this noise elimination ventilator that room temperature is raise in the north, and entering of air lock external noise effectively.Cooperate single window to close (filling out envelope window seam) room noise value and can reduce the 12-15 decibel with windowing to compare, cooperate double window to close and to reduce noise 18-20 decibel with windowing to compare.The requirement for restriction to noise is satisfied when sleeping night in own noise＜35 of this noise elimination ventilator decibel.
The utility model noise elimination ventilator is a case structure, can directly be placed in to compare easy for installationly on the windowsill with the silencer of bent-tube boiler, and volume is little.
Claims (3)
1, a kind of noise elimination ventilator is characterized in that casing is a case structure, and the one side in the sidewall of four sides is installed ventilating fan, opens the air port in its relative one side, and horizontal obstruct is set in the casing, and laterally intercepting is a fan-shaped column, forms labyrinth passage in casing.
2, according to claim 1, said noise elimination ventilator is characterized in that at the inwall of casing and laterally intercepts deadener all is set.
3,, it is characterized in that ventilating opening is provided with blind window and mosquito-proof net according to claim 1,2 said noise elimination ventilator.
