Description

A kind of self-priming high-efficiency cooking fume exhauster

Technical field

The present invention relates to a kind of range hood, relate in particular to a kind of self-priming high-efficiency cooking fume exhauster machine, can be used for the environment that kitchen, dining room, restaurant and other easy production and processing places (like welding shop) that forms oil smoke etc. have oil smoke, fog pollution.

Background technology

In recent years, along with improving constantly of people's living standard, people are also more and more higher to the requirement of quality of life, and range hood has become and requisitely under the environment that family, dining room, restaurant etc. cause fume pollution easily removed oil smoke equipment.Range hood a great variety in the market, different modeling mostly adopt the running of motor driven blower fan with regard to its basic principle, is discharged outdoor method with indoor dusty gas by afflux cover suction smokejack.

Mostly there are some defectives in the generally popular in the market oil smoke that removes, remains further to be improved.At first; No matter be updraft type, side-suction type or other forms of range hood; All be that fan directly is contained on the axis of motor; Motor is accounting for the centre position, the thrust air-flow that fan blade produces be dispersed in motor around, produce the air-flow whirlpool; Because turbo blade disperses air-flow; In fact reduced the swabbing action to oil smoke, efficient is relatively low, and energy loss is bigger.Secondly, motor and casing thereof are arranged in the middle of the cigarette road, will inevitably cause the secondary oil smoke pollution, can have influence on the service behaviour of motor and turbo blade for a long time in the past, and the cleaning difficulty is also relatively large.Once more; Because the rotation and the vibration of motor itself; The rotation of fan blade and vibration; The whirling vibration of air-flow; The vibrations of casing can make that all range hood produces certain noise in the course of the work, though the smoke exhaust ventilator noise of some brand is less relatively; But all be to realize, just can cause the complete machine cost higher relatively unavoidably through precision and the performance that improves motor, bearing connection etc.In addition, not too big at oil smoke, need not to start under the situation of range hood, relatively poor relatively through the natural exhaust of oil smoke effect of smoke exhaust ventilator, will cause environmental pollution to a certain degree like this.In addition, present smoke exhaust ventilator generally all is applicable to family, and relatively poor relatively to dining room, restaurant and other processing site adaptability that forms oil smoke easily, the time has been grown the environmental pollution that will have influence on these places and increased the weight of.

Patent CN200610154878.6 " a kind of smoke exhaust with wind deflector " has proposed a kind of smoke exhaust with wind deflector; Improved the mist extractor efficient of range hood to a certain extent; But its basic principle still adopts motor driven turbine rotation mode; Remove the oil smoke effect and can't really realize qualitative leap, generating noise also can hardly be avoided simultaneously.Patent CN03149853.1 " the full-automatic smoke exhaust ventilator of a kind of magnetic suspension drum-type rotator type " has proposed the energy-conservation full-automatic smoke exhaust ventilator of a kind of magnetic suspension drum-type rotator type; Can reduce frictional resistance to a certain extent; Reduce noise; Improve and remove the oil smoke effect, but the design of its huge mechanical system makes it be difficult to really obtain promoting.

Summary of the invention

The object of the present invention is to provide a kind of self-priming high-efficiency cooking fume exhauster.

The present invention is a kind of self-priming high-efficiency cooking fume exhauster; Oil baffle 20 is installed on the casing 12; Oil baffle 20 is provided with the first oilhole 20a; Oil strain plate 11 tops link to each other with casing 12; Oil strain plate 11 is provided with the second oilhole 11a; Oil baffle 20 reaches wind deflector 15 with Koln and links to each other; The both sides, top that Koln reaches wind deflector 15 are provided with curved dop 15b; Both sides, its underpart are provided with the flute profile bayonet socket 15a that is connected with casing 12; The curved dop 15b that the bottom of oil strain plate 11 and Koln reach the both sides, top of wind deflector 15 fits; Koln reaches air self-priming mechanism by blower fan 23; Impeller 30; Filtering cover 16; Bracing frame 28; Support ring lower lip wall 26 is formed with support ring upper lip wall 27; Blower fan 23 is fixing with outer cover 22 through bracing frame 28; Support ring 9 links to each other with outer cover 22; The nipple 16a of filtering cover 16 is connected with outer cover 22; Filtering cover 16 is provided with the 3rd oilhole 16b; Reach in Koln on the chamber wall of annular air cavity 25 and offer air inlet 24; Koln reaches annular air cavity 25 and communicates with air cavity 8; The opposite side that reaches the chamber wall of annular air cavity 25 in Koln is offered exhaust finedraw 31; Contiguous Koln reaches surperficial 32 connection exhaust passages 6; The end of exhaust passage 6 is an exhaust outlet 7, and exhaust finedraw 31 communicates with central lumen 33.

The invention has the beneficial effects as follows:

1, changes the conventional electric-powered machine and drive the turbine rotation except that the oil smoke mode; Adopt Koln to reach the air self-priming apparatus; Rotate through the motor-driven small impeller; Oil smoke is imported Koln reach annular chamber; Oil smoke reaches the surface when the central lumen through the exhaust finedraw along Koln; Form air negative pressure in central lumen, the oil smoke of lampblack absorber inner chamber is attracted to discharge through central lumen in a large number, improved greatly and removed oil smoke efficient.

2, producing under the less situation of oil smoke, the extraneous oil smoke that produces gets into the lampblack absorber inner chamber through oil baffle cross laminates oilhole on the oil baffle and the oil strain plate cross laminates oilhole on the oil strain plate, can be implemented under the open state not except that the oil smoke effect.

3, adopt Koln to reach oil smoke that wind deflector produces the external world and draw polymerization efficiently in and import the lampblack absorber inner chamber, reduce the aerial loss of oil smoke.

4, adopt the motor-driven small impeller to remove the oil smoke mode, can reduce the frictional resistance in the motor to greatest extent, make it reach good energy-conserving effect, the low pollution, few noise.
