When the flowing of oil smoke improve the oil smoke effect of smoke exhaust ventilator 100 to achieve the purpose that smoke exhaust ventilator 100 to the powerful absorption of oil smoke
Fruit.
As shown in Figure 1, blower fan system 2 is located at the side of body 1, oil smoke flows from bottom to top along air duct 34, and passes through machine
Body 1 flows to blower fan system 2, and blower fan system 2 is located at the side in air duct 34, as a result, the fume-exhausting of blower fan system 2 and oil-collecting petticoat pipe 3
Air duct 34 not in same channel, avoidable oil smoke flows directly into blower fan system 2.So as to prevent oil smoke to a certain extent
It is attracted on blower fan system 2, to can avoid or reduce pollution of the greasy dirt to blower fan system 2, improves the clear of smoke exhaust ventilator 100
Clean degree reduces cleaning difficulty.
Smoke exhaust ventilator 100 according to an embodiment of the present invention as a result, accessory fan work is to generate air-flow, and air-flow is by going out
Air port 331 is blown out, so as to drive the flowing for flowing to the air stream that oil-collecting petticoat pipe 3 is surrounded, in the inner cover 31 of oil-collecting petticoat pipe 3
Negative pressure is formed in the space surrounded, and then can promote the flowing of the oil smoke in oil-collecting petticoat pipe 3, it is right to reach smoke exhaust ventilator 100
The purpose of the powerful absorption of oil smoke improves the oil smoke effect of smoke exhaust ventilator 100.
And blower fan system 2 is located at the side of body 1, and the air duct of blower fan system 2 and the fume-exhausting of oil-collecting petticoat pipe 3 is not same
It in one channel, is attracted on blower fan system 2 so as to reduce oil smoke to a certain extent, to can avoid or reduce greasy dirt pair
The pollution of blower fan system 2.
In some embodiments of the invention, blower fan system 2 may include braced frame 21, electric machine support 22 and motor
23, braced frame 21 is located at the side of body 1 and is connected with body 1, and the suction be connected with air duct 34 is defined in braced frame 21
Wind channel 211, electric machine support 22 are located in air-suction channel 211, and motor 23 is located on electric machine support 22, on the motor shaft of motor 23
Equipped with the wind wheel 231 for being suitable for generating air-flow.
Specifically, air-suction channel 211 is limited in braced frame 21, air-suction channel 211 is connected to air duct 34 and outdoor, motor
23 and electric machine support 22 be located at air-suction channel 34, motor 23 can directly be positioned by motor 23, the motor shaft of motor 23
It is equipped with wind wheel 231, motor 23 drives the rotation of wind wheel 231 to be suitable for generating air-flow, and support frame is connected with body 1 and is located at body
1 side.Motor 23 drives the rotation of wind wheel 231 to form negative pressure in air-suction channel 34 as a result, and flue gas passes through machine along air duct 34
Body 1 flows to air-suction channel 34, and is expelled to outdoor under the action of wind wheel 231.
Optionally, motor shaft can be arranged perpendicular to body 1.As shown in Figure 1, body 1 is vertically arranged, air-suction channel 34 is vertical
Body 1 is arranged, and motor 23 drives wind wheel 231 that can rotate around horizontal direction as a result, so that not only contributing to motor 23 drives wind wheel
231 rotations are also beneficial to flowing of the air-flow between air duct 34 and air-suction channel 211, and be conducive to blower to carry out air draught
The installation of system 2 is fixed, and the stability of blower fan system 2 is improved.
In some embodiments of the invention, what oil-collecting petticoat pipe 3 was formed as that Open Side Down is tubaeform.In other words, oil-collecting
The opening of petticoat pipe 3 is in tendencies toward shrinkage on direction from the bottom to top, and the lower ending opening of oil-collecting petticoat pipe 3 is towards cooking stove, in blower system
Under the action of system 2, the oil smoke that cooking stove generates can flow to the opening of oil-collecting petticoat pipe 3, and can lead to along the open flow of oil-collecting petticoat pipe 3
Tubaeform oil-collecting petticoat pipe 3 is crossed so as to preferably draw flue gas.As shown in Figure 1, the inner cover 31 and outer cover 32 of oil-collecting petticoat pipe 3 are equal

Under extend to the oil guide groove of 332 bottom of upper chamber.In other words, it can be equipped in the outside wall surface of the inner cover 351 of the first fillter section more
A oil guide groove, multiple oil guide grooves can circumferentially spaced setting along the inner cover 351 of the first fillter section and each oil guide groove along first
The inclined direction of the inner cover 351 of fillter section is extended to the bottom of upper chamber 332 by the upper end of the inner cover 351 of the first fillter section,
Specifically, each oil guide groove may extend to oil storage box 4, in this way, the filtered greasy dirt of multiple oil filter holes 311 can flow to oil guide groove,
Greasy dirt in each oil guide groove is eventually flowed in oil storage box 4 by oil guide groove.Greasy dirt is not only contributed to by oil guide groove as a result,
Convergence and flowing, and be also beneficial to greasy dirt being oriented to oil storage box 4.
Advantageously, oil filter hole 311 can be respectively equipped on the inner cover of the second fillter section 36 and third fillter section 37.Lead to as a result,
The inner cover 371 of the inner cover 361 and third fillter section of crossing the second fillter section can also carry out separating and filtering to oil smoke, so that collection can be improved
The filter effect of oil smoke cover 3, and then pollution of the greasy dirt to blower fan system 2 and air draught air duct can be reduced, while can also be further
So that pot and stove and food neat and tidy are without contaminated.
Optionally, assist the sectional area in air duct 33 that can be gradually increased from the top down.Oil-collecting petticoat pipe 3 is not only contributed to as a result,
Tubaeform structure formation, and assist air duct 33 lower end sectional area be greater than auxiliary air duct 33 upper end section
Product can form air amplification in the lower end in auxiliary air duct 33 as a result, pass through the end of the lower end in auxiliary air duct 33 convenient for accessory fan
Portion's structure carries out air amplification effect, to blow out powerful wind-force, negative pressure is formed to the oil smoke region of oil-collecting petticoat pipe 3, to be conducive to
The absorption of oil smoke.
