<P>PROBLEM TO BE SOLVED: To provide a drum-type washing machine with no fluid balancer, which allows detection of a fixing bolt for transportation that has been forgotten to be removed, for preventing a failure. <P>SOLUTION: Water is supplied into a water tub 182 rotatably incorporating a drum 178 that contains laundry and elastically supported within a washing machine body 183 in a swingable manner. Then, an acceleration sensor 188 is used to detect an acceleration change of the water tub 182 caused by movement of water within the water tub 182 occurring when the drum 178 is rotated by a motor 181, and detect existence or nonexistence of a fixing bolt 185 for transportation, thereby accurately detecting the fixing bolt that has been forgotten to be removed during transportation, so that a failure caused by abnormal vibration and the like during washing and dewatering can be prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
