PROBLEM TO BE SOLVED: To provide a dish washer/drier high in washing performance. SOLUTION: The dish washer/drier is provided with: a washing tank 22 for storing washing water; a washing pump 26 for pressurizing the washing water; and a high-density oxygen adding means 38 for making oxygen-enriched gas with an oxygen density higher than that in air dissoluted in the washing water. The high-density oxygen adding means 38 is provided with: a discharging means 39 for jetting the high-density oxygen to a part of an oxygen storage tank 41 and the discharging path 37 of the washing pump 26; and a first electromagnetic switch valve 42 and a check valve 43 between the tank 41 and the discharging part 39. Thus, the quantity of activated oxygen in the washing water is increased and washing ability of the washing water is improved, thereby the dish washer and dryer sufficiently washes the dirt on the dish even without using a detergent.
