To provide a method of operating a disinfection cabinet capable of suppressing power consumption.SOLUTION: A disinfection cabinet circulates and supplies hot air generated by a heater and a blower to a storage chamber defined inside the casing, thereby heating and disinfecting and drying the dishes stored in the storage chamber. Disinfection cabinet is equipped with a disinfection and drying time for disinfecting and disinfecting dishes and disinfection drying process is performed and at the beginning of disinfection and drying process set room temperature of storage room to set temperature for sterilization disinfecting tableware , And holds it for a disinfection time that is shorter than the disinfection drying time. After the disinfection time has elapsed, the set temperature of the room temperature is changed to the set temperature for drying for drying the dishes lower than the set temperature for disinfection, and the setting temperature for drying over the remaining drying time of the disinfecting drying time To perform drying operation.(FIG.【課題】消費電力を抑制することができる消毒保管庫の運転方法を提供する。【解決手段】消毒保管庫は、筐体に内部画成した収納室に、ヒータおよび送風機により生起された熱風を循環供給することで、該収納室に収納した食器を加熱して消毒乾燥する。消毒保管庫は、食器を消毒乾燥する消毒乾燥工程が行われる消毒乾燥時間が設定され、消毒乾燥工程の初めに、収納室の室温の設定温度を、食器を消毒するための消毒用設定温度に、消毒乾燥時間より短かい消毒時間に亘って保持する消毒運転を行う。そして、消毒時間の経過後、室温の設定温度を、消毒用設定温度より低い食器を乾燥するための乾燥用設定温度に変更して、消毒乾燥時間の残りの乾燥時間に亘って乾燥用設定温度に保持する乾燥運転を行う。【選択図】図3
