PROBLEM TO BE SOLVED: To provide a water supply device where locking of a centrifugal motor is prevented even if dust or the like enters a centrifugal water supply pump. SOLUTION: An impeller 8b for supplying water is not directly connected to the centrifugal motor 8e. Even if the impeller 8b is locked and stopped when foreign matter such as dust entering a water tank 2 and passing through a filter 8a enters the centrifugal water supply pump 8, the centrifugal motor 8e of the centrifugal water supply pump 8 is not locked and stopped and the failure of the centrifugal motor 8e can be prevented. The need to replace the expensive centrifugal motor 8e because of the failure of the centrifugal motor 8e is eliminated and the cost of maintenance can be reduced. COPYRIGHT: (C)2007,JPO&INPIT
