1 is tilted whereby a front side of the rotating drum 1 becomes higher than a back side of the rotating drum 1 other elements are the same as those of the first embodiment and have the same reference marks so that the descriptions of those elements are omitted here in a washing process detergent bubbles are poured onto a laundry such as clothes or textiles in a rotating drum 1 at that time the detergent bubbles are poured from the higher position of the rotating axis i e the front side of the rotating drum 1 in a diagonal back direction an operation of a washing process is described hereinafter the detergent bubbles are produced by the same method described in the first embodiment the detergent bubbles which are produced by continuous rotation of the rotating drum 1 rise in space between the rotating drum 1 and a tub 3 by centrifugal force and overflow from a front upper section of the washing machine the detergent bubbles are poured from the higher position of the rotating axis i e the front side of the rotating drum 1 in a diagonal back direction as discussed above the laundry is clustered at the lower side of the rotating drum 1 by tilting the rotating axis the detergent bubbles are poured onto the laundry in the rotating drum 1 from the higher position of the rotating axis in a diagonal back direction the.
