Description
Technical field
The utility model relates to architectural environment power-saving technology, in particular to a kind of rain and snow type ventilation by air passage device arranged side by side.
Background technique
National standard with reference to atlas 11CJ33 ventilation by air passage device arranged side by side from Chinese patent CN 201866883U,
CN102269460A etc., wherein CN 201866883U illustrates that its performance " can reach available ventilation area greater than roofing opening
80% ", and being spaced ventilation by air passage device is only " within 40% ", illustrates that air channel structure arranged side by side has very superior performance of ventilating
Advantage.But invention CN103206762A thereafter negates comprehensively to the rainproof function of above-mentioned patent, in background note: " passing through
The test of practice, the rainproof effect of ventilation by air passage device arranged side by side be not it is highly desirable, especially in rainstorm weather, the stream of rainwater
Speed is too quickly, and existing structure can not effectively be defendd, dredged, collected and be excluded to rainwater at all ", but in technical solution
On, " convex ribs " are arranged simply on flashing board only to slow down rainwater flow velocity in invention CN103206762A.Due to " rainwater flow velocity mistake
It suddenly is not " ventilation by air passage device arranged side by side anti-the main reason for not living rainwater, above-mentioned technical proposal does not solve " can not be to rain
Water is effectively defendd, is dredged, collected and is excluded " problem, and " the closing headstock gear waterproof " is even more that can not determine
The scheme of use premise condition, and close ventilation rainproof and also do not meet wind sheltering type Natural Ventilation Technology In One Green requirement.
The anti-incessantly rainwater of ventilation by air passage device arranged side by side is invalid technique, and performance of ventilating is high and invalid again, on
The structure rain-proof problem for stating patent is always existed and could not thoroughly be solved, and main cause is the rain-proof problem to air channel structure arranged side by side
Understanding is insufficient.In fact, the rain-proof problem of ventilation by air passage device mainly includes following aspect side by side: 1, to the rain-proof weight of flashing board
Folded understanding is insufficient, from CN201866883 U case Figure of description 4 as can be seen that design allows rainwater direct projection to bottom rain-proof
Plate or sink will lead to the rainwater splashed and fall into interior；2, multilayer flashing board connects draining and dredges to a large amount of rainwater caused by bottom
And queueing problem, this is that the distinctive flashing board of air duct type technology arranged side by side is in caused by unilateral oblique form, and the interval wind
The rainwater of road formula ventilator upper layer flashing board and middle layer flashing board 5 does not need then to be discharged to the exclusion of bottom flashing board；3, top air duct
It is open to lack rain-proof control function.Since there are above-mentioned technical problems, although ventilation by air passage device and interval air duct type are logical side by side
Wind device is equally using the way in bottom setting headstock gear, but the bigger rainwater of the big formation of air duct available ventilation area falls side by side
Filling amount causes the rain-proof of rainstorm weather rainfall and ventilator internal structure, the uncertain problem of drain function.
Snow defence is the guarantee sexual function with the ventilation by air passage device arranged side by side of rain-proof no less important, although above-mentioned patent is not bright
Really illustrate the snow defence function of its structure, but it is equally existed due to the open snowfall in top air duct and snow defence control problem.And
In fact, light snowflake, which has, to be more difficult anti-inorganization with the wind than rainwater and drifts characteristic, and will not be instant as rainwater
It flows away, when weather, snowflake flows backward from the open air duct in top to be easy to descend slowly and lightly onto bottom sink and the valve plate of closing
Face, necessarily leads to snow melt leakage after accumulated snow is more than rain-proof structure height, and Winter Snow can constantly gather inside ventilator, melt
Change, freeze to form the bigger slush mixture of load, it is sufficient to ventilator malformation be caused to destroy.
Based on the above issues, although foregoing invention CN103206762A clearly proposes the prior art, there are rainproof functions to lack
It falls into, but due to lacking substantive technological means, has to take following rain-proof, snow defence technical measures in practical application: 1,
It adds partition and becomes air duct arranged side by side to be spaced air duct, to block rain-impact lower layer flashing board.2, setting inclination almost horizontal is anti-
Rain plate, to reduce rainwater flow velocity.3, to dredge uncertain displacement, the big specification rhone of setting and opening and closing at bottom flashing board
Device.Above structure forms ventilating-type shielding and the blocking to air duct arranged side by side in various degree, can not be formed and improve effective roofing
Natural Ventilation Technology In One Green, it is even more impossible to guarantee the big performance of ventilating advantage of air channel structure available ventilation area arranged side by side.
In addition, there is also real abdomen frame boards to influence daylighting function, lacks and guarantees that installation strength is asked for ventilation by air passage device side by side
Topic.Since ventilation by air passage device valve plate arranged side by side is arranged in bottom, causes valve plate dust stratification dirt that can not clean influence daylighting function, exist
Valve plate can not Maintenance and Repair and damage falls indoor danger and valve plate condensation is directly dripped into indoor problem.
In product cost, ventilation by air passage device arranged side by side there is also due to frame board merogenesis combined frame intensity it is low, lack guarantor
The overall skeleton intensity of card and basis installation, product mix installation also need to design a large amount of foundation structures and increase building cost cost
Problem.
