ABSTRACT:
The cool air inside a refrigerator compartment2is introduced through a return opening10into an ion generation chamber45provided behind the refrigerator compartment2. A voltage is applied to a needle-like electrode11aarranged in an upper portion of the ion generation chamber45so that, by corona discharge, positive and negative ions are discharged substantially parallel to the cool air circulating in the direction indicated by arrow B2. This helps alleviate the loss of ions resulting from collision with a wall surface, and permits the ions to reach a wide area. This prolongs the period for which the cool air is kept in contact with the ions, and thus helps enhance the sterilizing effect.
