STERILIZATION METHOD OF ICE TANK OF WATER TREATMENT APPARATUS

摘要

PURPOSE: The sterilization method of the ice tank of a water processor is provided to sterilize and wash an ice tank by providing sterilized water and purified water to the ice tank of a water processor, spray by using an air pump for complee sterilization and cleaning, and use a flow path change valve in order to provide sterilized water and purified water for the optimization of a flow path. CONSTITUTION: The sterilization method of the ice tank of a water processor includes the following steps. An ice discharging step discharging an ice kept in an ice tank and sensing whether totally discharged or not through an ice discharge time and an ice residual quantity sensing; a first sterilization step spraying the sterilized water to the ice tank through an air pump; a second cleaning step spraying purified water to the ice tank through an air pump. The ice discharging step includes the following steps. A step sensing an residual ice quantity in an ice tank; a discharge completion step stopping an ice discharge in case the residual ice quantity is not sensed and a second discharge time is over.
