面が考えられる。(Embodiment 5) In each of the embodiments described above, the light irradiation means is turned off while the door of the ice making device is open. When TiO 2 is used as the photocatalyst 5, as described above, a black light or the like containing ultraviolet light is installed as the light irradiating means 4. However, when the door of the ice making device is opened, the user makes an ice tray for supplying water. When taking out the ice 2, taking out the ice, or cleaning the ice tray 2, there may be a scene where the user looks into the ice making device.

で、マイコン１２ａは光照射手段４をオフする。In such a case, it is necessary to consider safety so that ultraviolet rays do not enter the eyes of the user. For this reason, when the door of the ice making device is opened, the light irradiation means 4 is controlled to be turned off. As shown in the block diagram of the refrigerator in FIG. 12, when control is performed by the microcomputer 12a, the F door switch 21 causes the freezing room (F room) in which the ice tray 2 and the ice storage case 3 (ice making unit) exist. Is detected, the microcomputer 12a turns off the light irradiating means 4 until it is confirmed again by the F door switch 21 that the door 22 is closed.

消費電力を抑え、省エネルギー化を図ることができる。 According to the first aspect of the present invention, the decomposition and desorption of the odor component due to the decomposition of the photocatalyst are repeated on the inner surface of the ice tray, so that the effect is not deteriorated unlike the purification means using activated carbon. No need to replace. Further, since it is not necessary to raise the temperature to activate the catalyst, it is possible to operate the apparatus in a relatively low temperature part. Therefore, it is possible to provide the ice making water purification function even to a manual ice making device that has not been conventionally provided. In addition, purification action is necessary.
Turn on the light irradiator only when necessary
Power consumption can be suppressed and energy saving can be achieved.
