PROBLEM TO BE SOLVED: To provide a freezer-refrigerator capable of improving deodorization performance and saprophytic bacteria decomposition performance by photocatalyst and capable of producing delicious ice by using mineral water, spring water or the like.SOLUTION: The freezer-refrigerator includes: a feed water tank 1 placed in a cold room 101; a chill tray 4 placed in a freezer 103; a water feed pump 2 placed in the cold room to feed water in the feed water tank 1 to the chill tray 4; and a water feed pipe 3 for feeding water from the water feed pump 2 to the chill tray 4. A photocatalyst purifier 10 for deodorizing feed water to the chill tray 4 and decomposing saprophytic bacteria is placed in a water feed system in the cold room 101 out of the water feed pipe 3, the photocatalyst purifier 10 includes a light transmissive member (glass tube) coating the photocatalyst and a light source (LED 9) for irradiating the photocatalyst with light, the light transmissive member is inserted into the water feed pipe 3 so as to be functioned as a part of the water feed pipe 3, and the light source 9 is placed close to the light transmissive member on the back of the water feed tank 1. |
