Description
Technical field
This utility model relates to exhaust fan technical field, particularly a kind of Bladeless exhaust fan.
Background technology
Exhaust fan is a kind of generation air-flow, makes the spacelike controlled atmosphere electricity-saving appliance that indoor-outdoor air exchanges, it is therefore an objective to will remove the air pollution of indoor, be widely used in the place such as kitchen, toilet.Conventional exhaust fan uses driven by motor big blade to rotate and produces air-flow, utilizes cross-ventilation that indoor can be allowed to be constantly in negative pressure state, forms one suction, the continuously air outside suction chamber, and discharge room air, thus reach ventilated effect.This exhaust fan, after long-time use, big blade accumulates dust, and use in kitchen also can account for oil stain, not only cleans big blade extremely difficult, and the shape of big blade, surface smoothness and balance all can be affected, and exhaust performance declines.
Summary of the invention
In order to solve the problems referred to above that current fan blade exhaust fan exists, the utility model proposes a kind of Bladeless exhaust fan being easy to cleaning, good exhaust effect, simple in construction.
To achieve these goals, this utility model provides a kind of Bladeless exhaust fan, including casing, casing is provided with exhaustor, the two ends of exhaustor are respectively air inlet and gas outlet, it is characterized in that, it is additionally provided with air inlet pipe on described housing, aerator one and mozzle one, air inlet pipe is in the outside of exhaustor, interior gas groove is formed between air inlet pipe and exhaustor, interior gas groove is connected with exhaustor by jet groove, aerator one is arranged on the top of air inlet pipe, mozzle one connects aerator one and air inlet pipe, extend along the internal face direction tangential with air inlet pipe at the junction mozzle one with air inlet pipe.
This utility model uses aerator to carry out air and sucks and compression, the air sucked enters the interior gas groove of annular by mozzle one from the tangential angle of air inlet pipe, spraying to exhaustor through jet groove again, this air-flow drives the gas inspiration exhaustors such as the flue gas steam of indoor simultaneously, and is discharged to outdoor, air is compressed through aerator, simultaneously through narrow jet groove, the stream pressure of ejection can be bigger, and speed is faster, wind-force is higher, and exhaust effect is more preferably；Aerator is not in exhaust duct, flue gas steam etc. accumulates in exhaust duct and is gathered on aerator without bonding, also will not impact aerator, and exhaust duct is very easy to clean because not having big blade, exhaust fan structure is simple, clean easily and good operating stability, life-span are long.
Accompanying drawing explanation
Fig. 1 is Bladeless exhaust fan structure schematic diagram；
Fig. 2 is that the A-A of Fig. 1 is to cut-away illustration；
Fig. 3 is that the B-B of Fig. 2 is to cut-away illustration.
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Detailed description of the invention
Seeing Fig. 1 and Fig. 2, the casing 1 of Bladeless exhaust fan is provided with exhaustor 2 and two aerators: aerator 1 and aerator 2 32, and exhaustor 2 runs through casing 1, its two ends are respectively air inlet and gas outlet, after Bladeless exhaust fan is installed on wall, air inlet is in indoor, and gas outlet is in outdoor.Air inlet pipe 7 is arranged on the outside of exhaustor 2, forms the interior gas groove 8 of annular between air inlet pipe 7 and exhaustor 2, and interior gas groove 8 is connected with exhaustor 2 by jet groove 9.See Fig. 3, mozzle 1 connection aerator 1 and air inlet pipe 7, extend along the internal face direction tangential with air inlet pipe 7 at the junction mozzle 1 with air inlet pipe 7, mozzle 2 42 connection aerator 2 32 and air inlet pipe 7, extend along the wall direction tangential with air inlet pipe 7 at the junction mozzle 2 42 with air inlet pipe 7.Extraneous air is sucked and is compressed by aerator 1 and aerator 2 32, the air sucked enters interior gas groove 8 by mozzle 1 and mozzle 2 42 from the tangential angle of air inlet pipe 7 respectively, form a swirling air stream, the internal air being full of compression of interior gas groove 8, the air constantly entered from tangential direction makes the air-flow within interior gas groove 8 more smooth, it is not easy aerodynamic energy is lost, compressed air in interior gas groove 8 is from jet groove 9 spirt exhaustor 2, because jet groove 9 width is the least, the higher air-flow of air pressure is sprayed from jet groove 9, the sternward flowing in exhaustor 2 of the air of ejection forms air-flow, this air-flow drives the flue gas steam etc. of indoor to enter in the air inlet entrance exhaustor 2 from exhaustor 2 front end simultaneously, and it is discharged to outdoor from the gas outlet of exhaustor 2 rear end.
Seeing Fig. 1 and Fig. 3, aerator 1 and aerator 2 32 be arranged on the upper left corner and the position, the upper right corner of air inlet pipe 7 with being respectively symmetrically, so arrange and have following benefit: two aerators work simultaneously, ejection air-flow is more fierce；When wherein an aerator breaks down, there is another aerator maintenance work, the reliability of exhaust fan can be improved；Symmetrical expression installs aerator makes outward appearance more attractive, and evenly, aerator rotates more steady casing stress, and abnormal sound is less；Because cooking fume is to flow from bottom to top, and is arranged the outside to exhaust fan by exhaustor, it is not easy to be inhaled in aerator.
See Fig. 2, jet groove 9 is outside the inlet port of exhaustor 2, flowing from jet groove 9 air-flow out to the direction, gas outlet of exhaustor 2, the inlet port at exhaustor 2 can form air pressure air-flow strong, fireballing, indoor steam flue gas etc. can be brought in exhaustor 2.Jet groove can also be arranged on other positions of exhaustor 2.
Seeing Fig. 2, be provided with the kuppe 5 being connected with gas outlet outside the gas outlet of exhaustor 2, kuppe 5 is in round tube shape, and its size, as gas outlet, is highly convenient for being connected with gas outlet.In the case of pulling down deep bead 6, the outer end of kuppe 5 can connect discharge hose, such design be user-friendly to discharge hose change vent position with towards.Kuppe can also be other shapes.The outside of kuppe 5 is provided with barge board 6, barge board 6 is rotatably connected with the top of kuppe 5, and it is outward-dipping, barge board 6 can prevent outside air from inversely flowing into exhaustor, and prevent the rainwater of outdoor, dust etc. from entering exhaustor, and when aerofluxus outward, the automatic levitating of barge board 6, allow air-flow flow to outside smoothly.
The Bladeless exhaust fan that this utility model provides, use aerator to carry out air to suck and compression, after air sequentially passes through interior gas groove and jet groove, forming air pressure air-flow strong, fireballing in entering exhaustor, indoor flue gas steam etc. is sucked and is discharged to outdoor, air is through overcompression, air pressure can be bigger, the air velocity of ejection is bigger, and wind-force is higher, and exhaust effect is more preferably；Aerator is not in exhaust duct, flue gas steam etc. accumulates in exhaust duct and is gathered on aerator without bonding, also will not impact aerator, and exhaust duct is very easy to clean because not having big blade, exhaust fan structure is simple, clean easily and good operating stability, life-span are long.
