Embodiment 1

[0025] see Figure 1 to Figure 7 , a sound-proof ventilation window with a combined sound-absorbing box, including a sliding window 1 and a sound-absorbing box 2, the sliding window 1 is two transparent glass windows that can be freely opened up and down, and the sound-absorbing box 2 is composed of an external box body 3 and a combination The muffler 4 constitutes.

[0026] A push-pull handle 12 is installed on the lower right outside the right window frame of the upper part of the sliding window 1, which is convenient for opening the window and has the function of indicating the opening and closing state of the air inlet. If the push-pull handle is located on the right side of the window, the air inlet is in a closed state. , and the air inlet is open when the push-pull handle is located in the center. The maximum opening area of ​​the air inlet is the area of ​​the upper glass window. The lower two glass windows of the sliding window 1 are ordinary sliding glass windows. Si...

Embodiment 2

[0032] see Figure 8 , Figure 9 and Figure 10 , On the basis of Embodiment 1, the anechoic box 2 is changed from a horizontal setting to a vertical setting, that is, the anechoic box occupies the positions of the upper and lower sliding windows on the left. In this embodiment, the combined muffler can be drawn out from the right side of the outer box 3 . The indications of each part in the figure are the same as in Example 1.

[0033] Wherein, the sound-absorbing material plate 9 is divided into upper and lower groups, and the upper group corresponds to the outer glass sliding sash 5, which is the air inlet when the 5 is opened. The upper and lower groups of sound-absorbing material plates also form a cross-shaped sound-absorbing air duct.

[0034] When the outer glass sliding sash 5 is in the open state, the air enters the upper set of sound-absorbing material plate 9 channels through the air inlet, then enters the lower set of sound-absorbing material plate 9 channels,...

Abstract

A soundproof vent window with a combined silencing box comprises a sliding window and the silencing box, wherein the silencing box is formed by an outer box body and a combined silencing body; the outer box body is formed by an outer glass push and pull window sash, an inner glass fixing window sash and a frame for connecting the outer glass push and pull window sash and the inner glass fixing window sash; the outer glass push and pull window sash becomes a wind inlet under an opening state; the combined silencing body comprises a bottom plate and two groups of silencing material plates; the two groups of silencing material plates arranged on the bottom plate are crossed in a cross shape to form a silencing wind path, thus achieving the soundproof and venting effects; all parts of the combined silencing body are connected into a whole and the combined silencing body can be drawn from the bottom of the outer box body. The soundproof vent window with the combined silencing box is simple and compact in structure, widely applicable and convenient to clean, can meet the needs of people on lighting, venting and denoising at the same time, and can effectively isolate the noise generated by traffic, industry, building construction and the like around a building.

Description

technical field [0001] The invention relates to a soundproof ventilation window for buildings, in particular to a soundproof ventilation window with a combined noise reduction box. Background technique [0002] Since the industrial revolution, the creation and use of various mechanical equipment has brought prosperity and progress to human beings, but it has also produced more and more noise. Noise pollution is regarded as one of the four major problems in the world today. One of the environmental problems. Noise mainly comes from traffic noise, industrial noise, construction noise and social noise, and its hazards include hearing damage, inducing various diseases, interfering with life and work, and so on. [0003] Housing construction is an important place for people to live and work. Modern people spend 80% to 90% of their time indoors living and working in the indoor environment. Therefore, the quality of the indoor acoustic environment directly affects people's health....
