Description
Technical field
A kind of umbrella formula air door of smoke exhaust ventilator, belongs to gizmology field.
Background technology
In existing smoke exhaust ventilator and spiral flue（Flexible pipe）Junction, be designed with unidirectional air door, with it is secondary prevent it is public
Flue gas in exhaust uptake, which drives in the wrong direction, to be circulated into oneself kitchen, however, air door used in now is mostly by two semicircles
The plastic tab of type（Thickness is between 1-1.5 millimeters, abbreviation halfround bar slice）Make, the halfround bar slice of this air door is by setting
Spindle nose at air door both ends, in the axis hole above the supporting plate of air channel（Axis hole is arranged in the side wall of duct main）, peace
The air door installed can rotate up opening in vertical state under the impact of smoke exhaust ventilator air-flow, so as to reduce to greatest extent
Resistance of the air door to air-flow；When smoke exhaust ventilator is stopped, two pieces of halfround bar slices of air door return by the gravity fall of itself again
Position is restored, so as to prevent flue gas（Counteroffensive）Pour in down a chimney.But above-mentioned air door is in use due to the bonding effect of greasy dirt（By oxygen
It is a kind of sticky colloid after the high-temperature oil smoke aggregation of change）, there is because of secund（There is one piece of halfround bar slice to be inclined to other side）
Or it is still in plumbness and is unable to two big defects of automatic homing, it is therefore desirable to is improved.
The content of the invention
The purpose of the application is to provide for a kind of umbrella formula air door of smoke exhaust ventilator, eliminates drawbacks described above with this, the air door
Using inverted umbrella-shaped structure（Umbrella is turned around use）；The air door is arranged in a segment pipe of air outlet upper end inwall
（In the segment pipe for setting the top of semi-circular air door originally, original air door and supporting plate all remove vacating space)；The wind
Door is made up of crossbeam, middle rod, upper nest and umbrella cover；Crossbeam is arranged in the intermediate inner wall above air outlet of smoke exhauster, crossbeam

It is fixed on the inwall of air outlet；
The rod in one section of connection below the middle part of crossbeam, middle rod are shaped as one section of cylinder（Refer to connected with handle of umbrella that
One section of cylinder）, the upper end of middle rod and beam vertical molding are connected as a body；Vertical middle rod is located at the circle centre position of air outlet；In
The length of rod is more than height when umbrella cover is folded up packing up；Ensure that umbrella cover there are enough folding activity spaces with this；
Nest is connected with the bottom of middle rod（Finger is connected with umbrella frame and fixes which part of umbrella frame one end, calls
Nest）, upper nest select 4-8 grooves that；The shape of upper nest and umbrella are identical with nest（Belong to public technology, its architectural feature is herein
It is not described in detail）；The bottom of upper nest and middle rod is fixedly linked integrally；
Umbrella cover is installed in each reserved groove of upper nest, umbrella cover is made up of 4-8 pieces of identical plate bodys, every piece of umbrella cover
Plate shape makes the triangle with circular arc（That partial shape of tellurion paster）；Behind plate body one side of every piece of umbrella cover on one side
Thin finger lateral cross section）, its cross section is acute angle type；Made in the plate body bottom of every piece of umbrella cover have with upper nest it is supporting be connected it is be hinged
Seat（There is the connection member of part hinge shape, be hinged seat）, hinged seat and umbrella cover are fixedly linked integrally；I.e. every piece of umbrella cover leads to
The perforation crossed on hinged seat（Equivalent to the hole for wearing hinge axis）It is fixed on iron wire series winding in the preformed groove of upper nest；Fix
Every piece of umbrella cover all carry angle of inclination, inclined angle is equal to the thickness of the webbing of umbrella cover；In every two pieces adjacent umbrella cover phases
There is the part of overlapped pressure stubble at the edge at the place of connecing, and the width of its overlapping pressure stubble part is no more than 5 millimeters；Every piece of umbrella cover
The mode and order of pressed and overlapped stubble are all identicals（It is consistent to press the direction of stubble）；Mounted every piece of umbrella cover forms one
The fimbriatum of segment-shaped（Refer to the shape of umbrella cover when opening just as a rice bowl put on the table）；Mounted umbrella cover can be according to
Flexibly outwardly opened by the gravity of itself, the umbrella cover after opening naturally can just block the annular flat being arranged in air outlet
The hole in face（Refer to be originally used for two pieces of semicircle air doors matched sealing process that circular ring type plane hole）；Often
The plate body of block umbrella cover can come under the blowing force effect of wind to be synchronously folded up packing up below, and the umbrella cover ovalisation after packing up is hanged
Hang down at the center of air outlet；Streamlined umbrella cover can be reduced when smoke exhaust ventilator is evacuated to greatest extent after this folding
Gas-flow resistance；And also help and collected by oil smoke forms the dirty of thick gel, reduce remaining to a certain extent
In the bonding resistance of the oil smoke colloid of smoke exhaust ventilator.
The application is beneficial to be had the technical effect that：The umbrella formula air door of smoke exhaust ventilator can be suitable under the gravity power effect of umbrella cover
Profit playback, completely eliminates the defects of flue gas pours in down a chimney.
