Problems solved by technology

The disadvantage of this method is that it is not very convenient to open or even impossible to open, and it cannot make full use of natural ventilation when the outdoor environment is good.
In addition, the use of mechanical ventilation consumes a certain amount of energy, which is not very economical in terms of initial investment and operation, and the installation and maintenance are also relatively complicated.

Embodiment 1

[0033] Embodiment 1 (with reference to Fig. 1, 3, 5, 7, 14, 15):

[0034] This example is based on the general description, in order to adapt to different occasions and different people's window opening habits, and also to make further improvements in order not to affect the normal use when cleaning the sound-absorbing material in the sound-absorbing box 2 . In this example, filter screens (21 or 51) are installed on both sides of the window frame 1, or in other words, the muffler box 2 or the filter screen reel tube 5 are installed on both sides of the window frame 1. When people are used to only using the anechoic box 2 on one side, the anechoic box 2 on the other side can cover it with a cover plate 23 (with reference to Fig. 1, 3, 5, 7, 11, 12, 14, 15 ). When the sound-absorbing boxes 2 on both sides are made into a whole, a partition 22 should be added between them (refer to FIG. 11 ). When people were used to only using the filter screen reel tube 5 on one side, the un...

Embodiment 2

[0038] This example is a further improvement made on the basis of the general description or Example 1 in order to better isolate noise and prevent dust from entering the room. In this example (referring to Fig. 9, 10), the two ends of double-leaf folding window (41 and 42) and the outside of sliding sash 42 in it are all equipped with soft rubber strip 421 or brush strip 421' . Under the state that the double-leaf folding windows (41 and 42) become V-shaped air ducts, the soft rubber strip 421 or the brush strip 421 ' are used to block the double-leaf folding windows (41 and 42) and the filter screen (21 or 51), the gap that more or less exists between the movable sash 42 of the double folding window (41 and 42) and the single sliding window 3 . Because obviously, in Fig. 9, only draw the structure that the outer side of movable sash 42 is equipped with soft rubber strip 421, omit the schematic diagram of adding brush strip 421 ', what contacts with soft rubber strip 421 amo...

Abstract

A window which can ventilate and separate noise comprises a window frame and a window sash in the window frame. The window sash of the invention is a combining window sash composed of a layer of single-sash pushing and pulling window and a layer of double-sashes folding window, wherein, the single-sash pushing and pulling window is mounted in one side of the window frame by hinges, and can only shelter half of the window frame when closing the window; the double-sashes folding window is mounted in another side of the window frame by hinges, and can completely unfold and shelter wholly the window frame when closing the window. Two ends of the single-sash pushing and pulling window and the double-sashes folding window are respectively mounted with filtering nets. The invention can still have better ventilation condition, meanwhile reducing the noise without mechanical ventilation device. In addition, the silencing window can save space of mounting mechanical ventilation device, and the sound absorption material or the filtering net has the action of filtrating air, and the air indoor can be purified. So the initial investment and the operating economical efficiency are better, the installation and maintenance are more convenient.

Description

technical field [0001] The invention relates to a window structure capable of ventilation and noise isolation. Background technique [0002] With the continuous development of urban traffic and industrial development, noise pollution has become an environmental pollution problem that people cannot ignore. In buildings with serious noise sources in the surrounding environment, if the noise reduction or sound insulation measures are not effective, it will cause great harm to people's work, study and life in these buildings. With the progress and development of science and technology, people gradually realize the harm of noise, and begin to study the method of eliminating noise. There are two main ideas: 1. Eliminate at the source, which is an active way of thinking. This method is more effective for fixed noise sources; 2. Eliminate or reduce it in its transmission path. Especially important, such as the elimination of street construction noise, etc. In the second way, sinc...
