Embodiment Construction

[0014] Such as figure 1 , the exhaust duct of the high-rise residential building of the present embodiment comprises: be located at the top of the exhaust duct 1, be a hollow transparent passage 3 (preferably made of glass or transparent plastic), be located at the non-powered air cap on the upper end of the transparent passage 3. power hood2. The transparent channel 3 includes a hollow, upper and lower symmetrical upper frustum 31 and lower frustum 32 . This product utilizes solar energy to heat the air in the transparent channel 3, and the hot air rises, increasing the effect of pulling wind. Wherein, sunlight can directly shoot into the transparent channel from the slope of the transparent channel to heat the air, and the surrounding slopes of the transparent channel 3 can absorb light at any time during the day. The exhaust channel 1, the transparent channel 3 and the unpowered hood 2 are coaxially arranged.

Abstract

The invention provides an unpowered funnel cap with a good draft effect for an air vent channel. The unpowered funnel cap comprises a transparent channel and an unpowered funnel cap body, wherein the transparent channel is arranged at the top of the air vent channel and is hollow; the unpowered funnel cap body is arranged at a top port of the transparent channel; a bottom port of the transparent channel is formed in a top port of the air vent channel; the transparent channel comprises an upper hollow frustum and a lower hollow frustum which are symmetrical and integrated. The unpowered funnel cap for the air vent channel of high-rise housing is additionally provided with one hollow transparent channel on the basis of a conventional unpowered funnel cap, sunlight can directly enter into the transparent channel through the upper frustum on the transparent channel so as to heat air, and hot air has an ascending character, so that the draft effect is more obvious; the side wall of the lower frustum is opposite to a roof, so that heat radiation of the roof can directly enter into the transparent channel through the side wall of the lower frustum, and further the air in the transparent channel is well heated.

Description

technical field [0001] The invention relates to a non-powered air cap for an exhaust channel of a high-rise residence. Background technique [0002] The unpowered hood is to use the natural wind speed of nature to drive the turbine of the fan to rotate and the principle of indoor and outdoor air convection to accelerate and transform any parallel air flow into a vertical air flow from bottom to top to improve indoor ventilation. A kind of device, it does not need electricity, has no noise, can run for a long time, and removes indoor heat, moisture and foul air. It is rationally installed on the top of the roof according to the natural law of air and the principle of air flow, and can quickly discharge indoor heat. And dirty gas, improve the indoor environment. [0003] Due to the influence of the outdoor wind flow, the conventional unpowered hood located at the top of the exhaust duct sometimes has a less than ideal effect of pulling out the wind, so that the smell in the i...
