PROBLEM TO BE SOLVED: To provide an insect-proof screen door in which an atmosphere of medicine such as an insecticide spreads over the whole area of a screen easily, an opening is covered by the atmosphere, thereby surely preventing injurious insects from intruding, and which is stably equipped with a device therefor without dropping out.SOLUTION: A screen door is framed by left and right stiles and upper and lower rails, and an insect-proof screen is stretched in a framework. A main case equipped with an insect-proof gas generator for heating a medicine base material such as an insect-proof mat and an exhaust conduit connected to the main case for laterally sending an insect-proof gas transpired from the main case along the lower rail are fixed on the outdoor side of the lower rail. A plurality of nozzles are projectingly arranged on the exhaust conduit so that the insect-proof gas can be uniformly blown on a lower part of the insect-proof screen.COPYRIGHT: (C)2014,JPO&INPIT【課題】殺虫剤等の薬剤雰囲気がネット全面に行き渡りやすく、開き口がその雰囲気で覆われることにより害虫の侵入防止が確実となり、また、その装置が脱落することなく安定して装備される虫除け網戸を提供する。【解決手段】左右竪框と上下框とで枠組みされ、その枠組みの中に防虫ネットを張った網戸において、下框の室外側に、防虫マット等の薬剤基材を加熱する防虫気体の発生装置が装備された主ケースと、それから蒸散される防虫気体を下框に沿って横へ送気するために同ケースに接続される排気導管とを固着し、防虫ネット下端部に防虫気体を均等に吹き付け得るように排気導管に複数のノズルが突設されている。【選択図】 図1
