A refrigerator includes a deodorizer disposed in a cold air circulation path for deodorizing an atmosphere in the refrigerator. The deodorizer includes discharging means for producing ozone and ultraviolet rays by means of high-voltage discharge and a photocatalyst module for decomposing an odor component and injurious matter contained in the atmosphere by means of photocatalyst.

Refrigerator and deodorizer producing ozone by high-voltage discharge

A photocatalysis apparatus has at least one unit structure (). The unit structure has a photocatalyst module () and a pair of discharge electrodes () sandwiching the photocatalyst module. The photocatalyst module includes a photocatalyst and a three-dimensional ceramic mesh base carrying the photocatalyst. At least one of the discharge electrodes is a three-dimensional discharge electrode having an electrode body () and a conductive frame (). The electrode body consists of cells made of a conductive foil and has front, back, and side faces. The front and back faces are separated from each other by a predetermined distance and have a shape selected from a group including a honeycomb, a lattice, and a mesh. The side faces of the electrode body is covered with the conductive frame.
