Title: Drying oven
Inventor: SHAKUBO KOJI
IPC: B05D7/14
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To uniform temp. distribution in an oven by making hot air blow by enough air speed and air flow for agitating air in the oven without upsizing a blower and a hot-air generator. SOLUTION: Jet nozzles 5 for forming air flows going to the center from both left and right sides along the underside of a work W carried in an oven are formed in the neighborhood of the floor face on the side walls in the oven. As these jet nozzles 5 are respectively formed into an ejector by arranging a diffuser 7 at the front of a hot-air blowing nozzle 6, when hot air is made to blow toward the diffuser 7 from the hot-air blowing nozzle 6, the hot air sucks a relatively low temp. air in the oven from the inlet side when the hot air passes through the throat part of the diffuser 7 and a relatively high temp. hot air is made to blow out from the outlet side.  It is possible thereby to sufficiently agitate the inside of the oven and to roughly uniform the temp. distribution in the oven since low temp. air in the oven is replaced with high temp. air and hot air is made to blow out from the jet nozzles 5 by an air flow being several-fold of the hot air made to blow from the hot-air blowing nozzles 6.
