PROBLEM TO BE SOLVED: To charge the battery of a self-traveling cleaner wirelessly from a charging stand and make the floor area of the charging stand compact.SOLUTION: A wireless charging system for a self-traveling cleaner comprises: a self-traveling cleaner which includes a battery, a cleaning-and-traveling device, and a control part for driving and controlling the cleaning-and-traveling device by the electric power of the battery, and which cleans a floor surface while traveling on the floor surface; and a charging stand which is used to charge the battery. The charging stand includes a power supply coil and an excitation circuit for exciting the power supply coil. The self-traveling cleaner includes: a power reception coil for receiving electric power from the power supply coil by electromagnetic coupling; and a charging circuit for charging the battery by receiving output of the power reception coil. The power supply coil is mounted on the charging stand such that a magnetic flux is generated parallel with the floor surface, and the power reception coil is mounted on the self-traveling cleaner such that the magnetic flux is receivable parallel with the floor surface.SELECTED DRAWING: Figure 5 【課題】自走式掃除機のバッテリの充電を充電台からワイヤレスで行い、かつ、充電台の床面積をコンパクトにする。【解決手段】バッテリと掃除および走行装置とを搭載し前記バッテリの電力で前記掃除および走行装置を駆動制御する制御部を備え床面を走行しながら掃除を行う自走式掃除機と、前記バッテリを充電するための充電台とからなり、前記充電台は給電コイルと給電コイルを励磁する励磁回路を備え、前記自走式掃除機は前記給電コイルから電磁結合によって電力を受電する受電コイルと受電コイルの出力を受けてバッテリを充電する充電回路を備え、前記給電コイルは床面に平行な方向に磁束を生成するように充電台に設置され、前記受電コイルは前記磁束を床面に平行に受け入れ可能に自走式掃除機に設置されることを特徴とする自走式掃除機のワイヤレス充電システム。【選択図】図５
