Claims (8)

   A deodorizing unit having a blower that takes in the air in the storage chamber for storing the stored material and sends the air into the storage chamber, and an ion generator that generates ions by discharge is provided in the storage chamber, and is generated by the ion generator. A deodorization mode for deodorizing the air in the storage chamber with ozone, and a sterilization mode for sterilizing the storage chamber with ions generated by the ion generation device by reducing the discharge amount of the ion generation device compared to the deodorization mode. A refrigerator characterized by providing.   The refrigerator according to claim 1, wherein an ozone catalyst that decomposes ozone generated by the ion generator is provided in the deodorizing unit.   It is possible to switch between a first ventilation state in which the air that has passed through the ozone catalyst is sent out from the deodorizing unit and a second ventilation state in which the air that has not passed through the ozone catalyst is sent out from the deodorizing unit. The refrigerator according to claim 2, wherein the second ventilation state is set in the ventilation mode and in the sterilization mode.   A first passage that arranges the ozone catalyst and guides air that has passed through the ozone catalyst to the storage chamber, and guides air that is branched from the first passage between the ion generator and the ozone catalyst to the storage chamber. The deodorizing unit is provided with a second passage and a damper that switches the air passage to the first passage side during the deodorization mode and switches the air passage to the second passage side during the sterilization mode. The refrigerator according to claim 2.   The refrigerator according to any one of claims 1 to 4, wherein an indoor temperature of the storage room is higher than a freezing point.   The refrigerator according to any one of claims 1 to 5, wherein a low-temperature catalyst that adsorbs an odor component of air in the storage chamber is provided in the deodorizing unit.   The refrigerator according to any one of claims 1 to 6, wherein a discharge amount of the ion generator is varied in the deodorization mode.   88. The refrigerator according to claim 87, wherein the rotation speed of the blower is increased at the start of the deodorization mode, and the rotation speed of the blower is decreased after a predetermined time has elapsed from the start of the deodorization mode.
