The above-mentioned preferred version for the present invention, has been shown and described the ultimate principle of the present invention, principal character and advantages of the present invention.Those skilled in the art is it should be recognized that the present invention is not restricted to the described embodiments; the principle that the present invention is simply described described in above-described embodiment and description; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements both fall within scope of the claimed invention.Claimed scope is defined by appending claims and equivalent thereof.
Claims (1)
1. the operation principle of a centripetal air-flow oven is characterized in that, comprises the steps:
1), in bodice (8), air-flow heating generator assembly (10), oil-collecting device are set, hot-fluid is blowed to add in heat container (2) by air inlet or fresh air inlet (3) on air-flow heating generator assembly (10) end oil-collecting device, and by heating, container (2) upper and lower through hole is through erects or tilt upward the unidirectional pressure hot-fluid centripetal flow heat foods to adding in heat container (2) to hot-fluid from the bottom to top；
2), the air flow rate of hot-fluid centripetal flow or air supply velocity is forced more than gas outlet or the air-out flow of venthole or to go out wind velocity due to the air inlet on air-flow heating generator assembly (10) end oil-collecting device or fresh air inlet (3), the micro-pressure heating cavity (22) producing an opposing seal in adding heat container (2) is caused to improve the speed adding hot food, thus shorten the heat time heating time of food, improve work efficiency；
3), air inlet or the fresh air inlet (3) on oil-collecting device top passes through to arrange wind deflector or shunting muscle or brace rod (301) on the unit of air inlet or fresh air inlet (3) side, air inlet or fresh air inlet are cut off permutation and combination by wind deflector or shunting muscle or brace rod (301), hot-fluid is forced water conservancy diversion to become swirling eddy to force hot-fluid centripetal flow by air inlet or fresh air inlet (3), and rotational flow heats outside food from the bottom to top；
Or, the air inlet on oil-collecting device top or fresh air inlet (3) upper and lower end are connected unsettled annular opening by support member (302)；Hot-fluid is forced water conservancy diversion to become swirling eddy to force hot-fluid centripetal flow by air inlet or fresh air inlet (3), and rotational flow heats outside food from the bottom to top.
