<P>PROBLEM TO BE SOLVED: To provide a dishwasher for cleaning dishes more clean, and for improving an energy saving property by controlling a cleaning step on the basis of a result detected by a contamination detection portion for detecting contamination of wash water (and rinse water as needed), and by controlling a rinsing step on the basis of a result detected by a conductivity detection portion for detecting salt content contamination, or the like in the rinse water (and the wash water as needed). <P>SOLUTION: A light transmission portion is provided in at least part of a water suction pipe 11 for connecting a water storage chamber 6 to a nozzle pump 10. The outer periphery of the light transmission portion is provided with the contamination detection portion 23 including a light-emitting element 24 and a light receiving element 25 and detecting contamination of water flowing inside the water suction pipe 11, and the water suction pipe 11 is provided with the conductivity detection portion 26 for detecting constituents of the water flowing inside the water suction pipe 11. The cleaning step is completed on the basis of the result detected by at least the contamination detection portion 23, and the rinsing step is controlled on the basis of the result detected by the conductivity detection portion 26. <P>COPYRIGHT: (C)2013,JPO&INPIT |
