PROBLEM TO BE SOLVED: To solve a problem that a conventional cleaning of the Mahjong tiles executed by rearranging six faces of each tile and wiping dirt respectively is troublesome manual work, takes a time and labor and requires the experience and patience. SOLUTION: This Mahjong tile washing machine requires just simple work of setting the tiles in a rotating table for cleaning and putting on a switch, and allows anyone to simply and carefully clean the tiles despite of the experienced or the non-experienced.
