Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail：
A kind of lower exhaustion type fume exhauster, such as Fig. 1 to Fig. 7, including exhaust fume collecting hood 1 and the cabinet 2 of the lower section of exhaust fume collecting hood 1 is connected to, institute
Exhaust fume collecting hood 1 is stated including cover body 11 and smoke deflector 12, what the cover body 11 had an indent holds together smoke chamber 13, it is described hold together smoke chamber 13 have it is front
The bottom of chamber plane 132 at open 131 and rear of side, holds together smoke chamber 13 and is gradually contracted by the open incoming air area of 131 to bottom of chamber plane 132
Subtract, the smoke deflector 12 is installed on the front of smoke chamber 13, and after smoke deflector 12 is installed, smoke deflector 12 is formed with court with smoke chamber 13 is held together
The air inlet 14 of Xiang Zhengqian and vertical air intake passage 3.Lower exhaustion type fume exhauster of the present utility model, smoke deflector 12 is installed on cigarette
The front in chamber 13, exhaust fume collecting hood 1 has towards just front air inlet 14 and vertical air intake passage 3, makes suction hold together smoke chamber 13 in vertical
To flowing, change oil smoke flow direction, lift oil separation effect, at the same it is of the present utility model hold together smoke chamber 13 using by open
The cavity moulding that the incoming air area of 131 to bottom of chamber plane 132 is phased down, makes air intake be difficult in each side wall and bottom of chamber for holding together smoke chamber 13
The junction of plane 132 produces flow-disturbing and is vortexed, and reduces pneumatic loss, pneumatic noise is reduced, while what incoming air area was phased down
Cavity moulding, can effectively lift the flowing velocity of oil smoke, accelerate the smoke evacuation of exhaust fume collecting hood.
The air inlet 14 is located at the top of smoke deflector 12, it is described hold together smoke chamber 13 there is inclined upper side wall 133, the upside
Wall 133 is downward-sloping from front to back, makes air inlet 14 surround the cushion chamber 134 of section triangle with upper side wall 133.This practicality is new
Before and after described in type, refer to lampblack absorber in the face of the side of user for front, back to user side be after.Such as Fig. 3, it is described hold together cigarette
The upper side wall 133 in chamber 13 is downward-sloping from front to back, makes air inlet 14 surround the cushion chamber of section triangle with upper side wall 133
134, open 131 due to holding together smoke chamber 13 are less apart from the spacing of bottom of chamber plane 132, therefore, the present embodiment is provided with cushion chamber
134,134 pairs of wind entered from air inlet 14 of the triangle cushion chamber carry out water conservancy diversion steering, it is to avoid air intake directly collides bottom of chamber
There is stress after plane 132 to turn back, formed with air intake below and liquidated, and air intake vortex phenomenon occurs in air inlet；Simultaneously
The inclined design of upper side wall 133 so that air intake produces the rectification slowing effect of air intake in cushion chamber 134, is conducive to into wind direction
The flowing of the vertical air intake passage 3 of lower edge.Turn to and rectification slowing effect to make cushion chamber 134 reach preferable water conservancy diversion, it is described
Upper side wall 133 is 35 °～75 ° with the angle of horizontal direction.Illuminating lamp band 4, the illuminating lamp are installed on the upper side wall 133
4 light-transmissive air inlets 14 of band.Water conservancy diversion cushioning effect and illumination in the utility model, due to needing to take into account cushion chamber 134
The light of the light of light bar 4 sets the openings of sizes of angle and air inlet 14 thoroughly, if upper side wall 133 is larger with the angle of horizontal direction,
Then the water conservancy diversion cushioning effect of cushion chamber 134 has weakened；If upper side wall 133 is less with the angle of horizontal direction, illuminating lamp band 4
The light of light sets angle thoroughly to be increased through the difficulty of air inlet 14, needs the openings of sizes for increasing air inlet 14, once increase
The openings of sizes of air inlet 14, then can reduce the effect of cushion chamber 134, therefore, in the present embodiment, upper side wall 133 and level side
To angle adopt 45 °.
Smoke deflector of the present utility model 12 is mounted at the front of smoke chamber 13, and the smoke deflector 12 includes panel
121 and connector 122, the connector 122 is attached at the dorsal part of panel 121, and the bottom of connector 122 has bossed hook
123, the bottom of the cover body 11 is provided with the link plate 111 coordinated with hook 123.Magnet 5, the magnet 5 are provided with the cover body 11
The connector 122 of absorption smoke deflector 12, makes smoke deflector 12 be fixed on open 131 front.When installing smoke deflector 12, by smoke deflector 12
The insertion link plate 111 of hook 123 of lower section, the lower edge with smoke deflector 12 promotes the rotary fastening of smoke deflector 12 in holding together cigarette as axle center
At open the 131 of chamber 13, under the suction-operated of the inner magnet 5 of cover body 11, smoke deflector 12 is installed and fixed；When need dismantle smoke deflector
When smoke chamber 13 is held together in 12 cleanings, the upper edge of smoke deflector 12 is pulled, and the dismounting of smoke deflector 12 is completed by being drawn upwardly out smoke deflector 12.
As Fig. 7, cover body of the present utility model 11 adopt one drawing and forming, hold together smoke chamber 13 and have from open 131 to bottom of chamber
Plane 132 inclines the left and right side wall 135,136 and diapire 137 tightened up, and the diapire 137 is provided with the exhaust outlet of exhaust fume collecting hood 1
15, filter screen 6 is installed at the exhaust outlet 15.Cover body of the present utility model 11 adopt one drawing and forming, simplified processing process,
