PROBLEM TO BE SOLVED: To provide a food storage suppressing an operating ratio of an electrostatic atomizer and an air blowing means and preserving food fresh over a long time.SOLUTION: The food storage includes: the electrostatic atomizer 1 provided within the storage for storing food and generating charged microparticle water by electrostatic atomization the air blowing means 2 circulating air within the storage and diffusing the generated charged microparticle water within the storage and a control means 3 controlling the operation of the electrostatic atomizer 1 and the air blowing means 2. The control means 3 performs intermittent operation for repeating operation and stop of each of the electrostatic atomizer 1 and the air blowing means 2. In the intermittent operation, stop time of one cycle of the intermittent operation of the electrostatic atomizer 1 is set longer than that of one cycle of the intermittent operation of the air blowing means 2, and operation time of one cycle of the intermittent operation of the electrostatic atomizer 1 is set shorter than that of one cycle of the intermittent operation of the air blowing means 2. During one cycle of the intermittent operation of the electrostatic atomizer 1, at least two cycles of the intermittent operation of the air blowing means 2 are performed.COPYRIGHT: (C)2011,JPO&INPIT【課題】静電霧化装置及び送風手段の稼働率を抑えて食品を長期にわたって新鮮に保存することができる食品収納庫を提供する。【解決手段】食品を収納する収納庫内に設けられ静電霧化により帯電微粒子水を生成する静電霧化装置1と、収納庫内の空気を循環させ、生成した帯電微粒子水を収納庫内に拡散させる送風手段2と、静電霧化装置1及び送風手段2の運転を制御する制御手段3を備え、前記制御手段3は、静電霧化装置1及び送風手段2それぞれについて運転と停止を繰り返す間欠運転を行うものであり、前記間欠運転は、静電霧化装置1の間欠運転1サイクルの停止時間が送風手段2の間欠運転1サイクルの停止時間よりも長く、静電霧化装置1の間欠運転1サイクルの運転時間が静電霧化装置1の間欠運転1サイクル中の送風手段2の運転時間よりも短く、かつ、静電霧化装置1の間欠運転1サイクル中、送風手段2の間欠運転を少なくとも2サイクル行う。【選択図】図1
