In addition, when a large amount of food with a large amount of water is stored, or when the refrigerator door is opened and closed frequently during high humidity such as during the rainy season, the activated carbon absorbs a large amount of moisture, which reduces the deodorizing ability. There was something to do. The above problems have been encountered in deodorizing a refrigerator using conventional activated carbon. In view of the above problems, the present invention provides a refrigerator that effectively deodorizes the inside of the refrigerator and does not require replacement of activated carbon.
