PROBLEM TO BE SOLVED: To provide a refrigerator capable of increasing nutrient of vegetables without consuming water content necessary for photosynthesis.SOLUTION: A refrigerator has an ultrasonic wave oscillation part 42 for applying ultrasonic waves toward an upper storage container 36 stored in a vegetable chamber 16 and vegetables 100 stored in a lower storage container 38. Ultrasonic wave reflecting means for reflecting the ultrasonic waves are provided on wall surfaces of the upper storage container 36 and the lower storage container 38, so that not only the ultrasonic waves irradiated from the ultrasonic wave oscillation part 42 directly impinge on upper parts of the vegetables 100, but also the reflected ultrasonic waves impinge on other parts than the upper part of the vegetables 100, consequently stimulus can be imparted on the vegetables 100 in all directions, and the ratio of the increase of nutrient is therefore increased.COPYRIGHT: (C)2013,JPO&INPIT【課題】光合成に必要な水分が消費されずに野菜の栄養素を増量できる冷蔵庫を提供する。【解決手段】野菜室16に収納された上収納容器36と下収納容器38に収納された野菜100に向けて超音波を照射する超音波発振部42を有し、上収納容器36と下収納容器38の壁面に超音波を反射する超音波反射手段を設けることにより、超音波発振部42から照射された超音波が、野菜100の上部に直接当たるだけでなく、野菜100の上部以外の部分にも超音波の反射波が当たり、野菜100に対しあらゆる方向から刺激を与えることができるため、栄養素の増量の割合が増加する。【選択図】図2
