Examples

The present embodiment provides a curtain wall natural ventilator, as shown in fig. 1 to 3, comprising: the air conditioner comprises a first shell 1, wherein an air inlet 4 is formed in the first shell 1; the second shell is connected with the first shell 1, the first shell 1 and the second shell form a closed inner cavity together, the second shell is provided with an air outlet 3, and the air outlet 3 is communicated with an air inlet 4 through the inner cavity; set up the subassembly that keeps out the wind between air intake 4 and air outlet 3, keep out the wind and set up wind channel 6 and with the sound insulation mechanism that wind channel 6 is adjacent on the subassembly, the subassembly that keeps out the wind has first state and second state when controlled rotation, when the subassembly that keeps out the wind is first state, air intake 4 and air outlet 3 pass through wind channel 6 intercommunication, when the subassembly that keeps out the wind is the second state, air intake 4 cuts off through the subassembly that keeps out the wind with air outlet 3.

In this embodiment, the shapes of the first casing 1 and the second casing are not limited, however, considering the beauty of the first casing 1 and the second casing after being matched with a door window or a curtain wall, the first casing 1 and the second casing are preferably triangular prisms, so that the first casing 1 and the second casing can form a structure with a cuboid shape after being connected, and the first casing and the second casing can be conveniently matched and installed with the door window or the curtain wall. And the inside cavity of first casing 1, second casing then should set up to the pore of rectangular shape, and air intake 4 and air outlet 3 communicate through this pore, can be convenient for like this the circulation of air, and the subassembly that keeps out the wind then sets up in this pore to be convenient for control the break-make of air intake 4 and air outlet 3. In the present embodiment, the wind shielding assembly mainly controls the on/off of the air inlet 4 and the air outlet 3 through controlled rotation. The wind shielding assembly is provided with a wind channel 6, the wind channel 6 is a channel for external air circulation, when the wind shielding assembly is controlled to rotate, two ends of the wind channel 6 are respectively communicated with the pore channel when the wind channel 6 is in a first state, so that the purpose of communicating the wind inlet 4 with the wind outlet 3 is achieved, two ends of the wind channel 6 are respectively contacted with the first shell 1 and the second shell when the wind channel 6 is in a second state, so that the first shell 1 and the second shell block the wind channel 6, and the wind inlet 4 and the wind outlet 3 are blocked by the whole wind shielding assembly. When wind channel 6 was in the first state, realized indoor ventilation, noise in the outside air is when passing through wind channel 6, owing to the setting of the sound-proof mechanism adjacent with wind channel 6 for the noise that carries in the air is absorbed by sound-proof mechanism, thereby reduces the noise volume in the air, guarantees indoor quiet environment. In this embodiment, when the sound insulation mechanism is disposed at the wind shielding assembly, compared with the arrangement at the air inlet 4: the air enters the air inlet 4 from the outside substantially through a section, the flow speed of the air at the air inlet 4 is overlarge, and if the sound insulation mechanism is arranged at the position, the time for absorbing sound waves is short, and the noise reduction effect is not objective; compare in setting up in 3 departments of air outlet: the air outlet 3 is adjacent to the indoor environment, although the flow velocity of the air at the position is close to the slowest flow velocity in the air duct 6, the air at the position immediately enters the room after noise reduction, residual noise is propagated and attenuated indoors, and the noise reduction effect is still not ideal; when the sound insulation mechanism is arranged in the wind shielding assembly, the flow speed of air gradually decreases and basically tends to be stable due to the friction force and the blocking of an internal cavity structure when the air passes through the wind shielding assembly, the sound insulation assembly has a longer time for reducing the noise of the air, after the noise of the air is reduced, the residual noise of the air is gradually attenuated due to the blocking or friction effect in the air duct 6 before the air reaches the air outlet 3, and the residual noise is basically eliminated, so that the air entering the room basically does not carry noise, and the quiet indoor environment is ensured.

In some possible embodiments, in order to reduce the entrance of outdoor dust and the like into the room, a filter screen 5 is respectively disposed at the air inlet 4 and the air outlet 3 for filtering dust or other impurities in the outside air.

In some possible embodiments, since the first casing 1 is in contact with outdoor air and the second casing is in contact with indoor air, in order to reduce heat transfer from outdoor to indoor, a heat insulating strip 11 is provided between the first casing 1 and the second casing.

As a specific example of the soundproof mechanism, the soundproof mechanism includes a soundproof cavity adjacent to the air duct 6, and a cavity in the soundproof cavity is filled with soundproof cotton. In this embodiment, the cavity and the air duct 6 may be communicated or separated, and the sound-insulating cavity may be arranged to completely surround the air duct 6 or to partially surround the air duct 6. Moreover, the soundproof cotton is only a conventional implementation means of the inventor, and in other possible embodiments, the soundproof cotton can be replaced by other existing fillers which easily absorb sound waves.

It is further optimized that the air duct 6 is separated from the cavity of the sound-proof cavity by the sound-permeable membrane 14. The sound-transmitting membrane 14 is arranged to separate the air duct 6 from the cavity, and to prevent the soundproof cotton from being blocked by direct contact with air. The sound-transmitting film 14 is also convenient for the penetration of noise in the air, and the noise reduction effect of the soundproof cotton is improved.

Further, in order to prevent the humidity in the room from being affected by the excessive proportion of moisture in the outside air, hydrophilic cotton is arranged on the side surface of the sound-transmitting membrane 14 close to the air duct 6 to absorb water mist in the air.
