< Topic >Being simplicity, being quicker, reliability is higher, in addition the cost effect is higher, washing of the object and machine washing of the object which makes disinfection possible and disinfection method is materialized.SolutionsThis invention, the object (40), especially, medical care and/or the equipment for dentistry and/or the job instrument regards the method where machine you wash and disinfect and. According to this invention, until the object (40) the ultra wave washes in the water (30) in the working space (18), of the washing and disinfection system (10) after the washing of the object (40), becomes the remaining amount where the water (30) is stipulated, from the working space (18) it is discharged. The remaining amount of the water (30) which in the working space (18) remains is converted to vapor continuously, making use of the heating element (44) which in the working space (18) is arranged. The object (40) heat is disinfected making use of vapor in inside the working space (18), continuously, in order to dry the object (40), steam atmosphere inside the working space (18) is discharged from the working space (18).< Selective figure >Figure 1【課題】より簡単で、より迅速で、より信頼性が高く、またよりコスト効果の高い、物体の洗浄及び消毒を可能にする物体の機械洗浄及び消毒方法を具体化する。【解決手段】本発明は、物体(40)、特に、医療及び/又は歯科用機器及び/又は作業器具を機械洗浄及び消毒する方法に関する。本発明によれば、物体(40)は、洗浄及び消毒システム(10)の作業領域(18)において水(30)の中で超音波洗浄され、物体(40)の洗浄後、水(30)が規定された残量になるまで作業領域(18)から排出される。作業領域(18)に残った水(30)の残量は、続いて、作業領域(18)に配置された加熱要素(44)を用いて水蒸気に変換される。物体(40)は、作業領域(18)内において水蒸気を用いて熱消毒され、続いて、物体(40)を乾燥するために、作業領域(18)内の蒸気雰囲気が作業領域(18)から排出される。【選択図】図1
