Detailed description of the invention
Embodiment 1
As Figure 1-5, the present invention is a kind of structure of flow guide hood, duct main 1 outer setting fixed electrical machinery 8, duct main 1 is arranged to upper cover 2, lower cover 6 is screwed, upper cover 2 is provided with air guide ring 6-3 or upper cover 2 is combined to form air guide ring 6-3 with lower cover 6, air guide ring 6-3 top fixed electrical machinery 8, air guide ring 6-3 annular is arranged, lower end is connected with the peripheral connection bit 4-4 of air inlet base plate 7, hot-fluid air outlet 6-2 lower end is downward or be tilted to down, hot-fluid is flowed downward by straight line or is tilted to current downflow, air guide ring 6-3 lower end lower than hot-fluid air outlet 6-2 plane or air guide ring 6-3 lower end and hot-fluid air outlet 6-2 plane approximate horizontal, air guide ring 6-3 inwall forces hot-fluid to concentrate not diffusing downwards, suction is erect by wind wheel 5 by air inlet 6-1 after forming powerful annular airflow strikes foodstuff surface bounce-back, air guide ring 6-3 is connected to one with upper cover 2 socket bend backwards or screws fixing, or air guide ring 6-3 also can connect with lower cover 6 socket or screw fixing, or air guide ring 6-3 is wholely set with upper cover 2 or screws fixing, or air guide ring 6-3 also can be wholely set with lower cover 6 or screw fixing, hook 3 is fixed on upper cover 2 bottom, heat generating member 4 hangs in hook 3, heat generating member 4 arranges and is fixed on air-flow centre, air guide ring 6-3 air channel so that abundant distribute heat, improve heat energy efficiency, wind wheel 5 is arranged between duct main 1 upper cover 2 and lower cover 6, be fixedly connected with motor 8 axle, the corresponding air inlet 6-1 of wind wheel 5 carries out air draught, blast is produced after wind wheel 5 air draught, wind speed, blowout forced airflow, air guide ring centrifugal flow that 6-3 is formed flows out, hang the heat-generating pipe 4 being fixed on upper cover 2 bottom enter heat exchange to arranging during outflow, produce thermal current and blow to hot-fluid air outlet 6-2, by hot-fluid air outlet 6-2, required object is heated.Hot-fluid air outlet 6-2 is fixed on lower cover 6 surrounding, and heat energy penetrates hot-fluid air outlet 6-2 illumination to carry out width at required heating object and penetrate heating.Due to forced airflow be outer end blows to from the inner to heat-generating pipe 4 carry out heat exchange, air guide ring 6-3 inwall is that smooth accessible from top to bottom design or lower end outward flanging or lower end are no more than 5MM to in-flanges, reduce the obstacle in the process of air current flow, the lower end low superheat flow air outlet or roughly concordant of air guide ring inwall, after avoiding air-flow laterally to be thrown away from centrifugal wind wheel, directly can not spray to foodstuff surface, the heat energy of exchange makes full use of, reach energy-saving and environmental protection, improve operating efficiency.
The present invention is not limited to above-described embodiment, described motor shaft can be installed more than one wind wheel or heat radiation wind wheel 9, be dispelled the heat, heat object motor 8 by louvre 4-1, and duct main can divide upper cover, lower cover fixing formation duct main.Can also point upper cover, air guide ring, lower cover connect as one, those skilled in the art can also do various modifications and variations, under the spirit not departing from invention, all in the claimed scope of the present invention.
