Abstract

The utility model relates to a silencing ventilator for an enclosed soundproof window, which is composed of an outer frame, a window frame, a silencing ventilating box, an opening-closing board, and a fixing frame. One or a plurality of ventilating holes and the silencing ventilating box are arranged on the transverse frame or the vertical frame of the window frame, and the inner through opening of the silencing ventilating box are arranged in the ventilating holes; the surfaces of the ventilating holes are provided with the opening-closing board to manually control the opening or the closing of the inner through opening. One or two ventilating holes are opened at the lower part of the track of the bottom beam of the outer frame, and the opening position is aligned with the outer through opening of the silencing ventilating box to make outdoor sir flow into a room through the inner through opening of the ventilating box. Because the air flows through the silencing section of the silencing ventilating box, then the air flows into the room through the inner through opening of a ventilating section to have the soundproof effect.

Description

The noise reduction gas permeable devices of enclosed type soundproof window

The utility model is the noise reduction gas permeable devices of relevant a kind of enclosed type soundproof window, particularly at the able to turn on or off noise reduction gas permeable devices of air hermetic enclosed type soundproof window.

Development along with nation-building, the means of transportation and the vehicles extend to the rural area by the city, town and country are flourishing flourishing because of traffic, also bring noise pollution because of traffic is flourishing, comprise the vehicles (as locomotive, automobile, train, aircraft etc.), factory's construction waits the various noises that produced, and makes to be near the household of noise source, the puzzlement that noise is stood by office, changes in fact at home and necessity of working environment; Because of the centralized dwelling house in city, too press close to each other simultaneously, so that each interior at home noise that activity produced (comprise the household appliances sound, the confused noise of voice or quarrel etc. are made a noise in crying of child or pet), all can the phase mutual interference.

Is a kind of after window is closed substantially at present, makes it the gap with urgent means and eliminate fully and reach effect airtight, sound insulation with the window that blocks indoor external noise.Utilize the airtight effect that reaches sound insulation, certainly will cause indoor-outdoor air not circulate, make the people indoor because of oxygen deficiency lassitude, often this was also unhealthful in the past, and common air pressure because of indoor and outdoor, temperature imbalance, cause the glass of window often to adhere to water smoke, influence printing opacity.

The purpose of this utility model has the noise reduction gas permeable devices of the enclosed type soundproof window of soundproof effect when being a kind of can breathing freely is provided.

For reaching above-mentioned purpose, the technical solution of the utility model is:

The noise reduction gas permeable devices of enclosed type soundproof window mainly is made up of housing, window frame, the ventilative box of noise reduction, keying plate and fixed border, it is characterized in that:

Offer one or more air-vents on the horizontal frame of window frame or straight frame, the bottom girder of housing is offered one or two air vent below its track, and offering the position is the outer port of aiming at the ventilative box of noise reduction;

The noise reduction box of breathing freely is long square type box-like body, places in the ducted body of horizontal frame or straight frame, and is inserted by the outside by fixed border and to be fastened, and the air vent place of one end and housing establishes extends gas hood, with steering current through pass in and out herein; Each is divided into noise elimination part and ventilative portion with half, and the below, end of noise elimination part is a gas hood, is outer port in the middle of the gas hood, is provided with the dividing plate that forms the air-flow zigzag path in the noise elimination part, is hollow in the ventilative portion, and its front is a porous plate, to connect outside in it.

Wherein, the noise elimination part inwall of the ventilative box of noise reduction comprises that the surface of dividing plate is provided with the intensive prominent bar of hair shape.

Wherein, the face portion of the ventilative box of noise reduction is provided with the plane chute of a depression, slides betwixt for opening and closing plate.

Wherein, the air-vent of being offered on the horizontal frame of window frame or the straight frame, with a fixed border in addition frame cover its edge, the back of fixed border is provided with extended trip, the mat trip passes air-vent by the inner face of horizontal frame, fastens with the ventilative box of noise reduction and interfixes.

Wherein, opening and closing plate is a long rectangle plate body, and the surface is provided with coarse lines or little lobe and pushes away for finger and hold mobile force surface, slides between the chute of the ventilative box of noise reduction and fixed border and does sealing or unlatching.

The utility model has the advantages that significantly device is at the horizontal frame of window frame or the ventilative box of noise reduction in the straight frame, after window closed, the air of indoor and outdoor still can circulate naturally or ordered about by external force and circulate; The ventilative box of noise reduction partly is made up of with ventilative two noise reduction, owing to be provided with the dividing plate that forms the air-flow zigzag path in the noise elimination part, and on the surface in noise elimination part inwall and next door the prominent bar of hair shape that absorbs sound wave is set, when making the indoor-outdoor air circulation, also has soundproof effect.
