PROBLEM TO BE SOLVED: To provide a steam type weeding tool making steam penetrate deep into root parts, since in conventional weeding tools, as to a motor type one, root parts remain and sprout again, and as to a fire type one using petroleum or the fire type one using a gas cylinder, it accompanies some risk, and since flame does not penetrate to the root parts, there is a risk of sprouting again.SOLUTION: By small-sizing a steam generation can A, and making a heat-generating part E have a large area by forming it as a conical shape such as B so as to generate steam quickly, it becomes possible to use the tool quickly.COPYRIGHT: (C)2012,JPO&INPIT【課題】従来の除草器具に於て、モーター式は根元が残り再び生えて来る。石油による火災式又はガスボンベによる火災式は危険がともない、火炎が根元まで浸透せず、再び生えるおそれが有るので、根元深くまで浸透する蒸気式除草器具を提供する。【解決手段】蒸気缶Aを小形化し、早急に蒸気が発生するように発熱部EをBのように比熱面積を円堆形にすることで面積が大きくなり、早急に使用が可能になる。【選択図】図5
