Problems solved by technology

Therefore, there is a problem that the influence of heat becomes large, and the price becomes high.
[0006] In addition, when a deodorizing device is installed in the air-conditioning passage and ultraviolet light-emitting diodes are used, it is impossible to directly visually confirm the state of deodorizing and sterilizing
For this reason, there is a problem that the case of sterilization cannot be distinguished

Abstract

An aim of the invention is to provide a refrigerator with improved deodorization and degerming performance. The refrigerator of the invention is characterized by comprising the following components: a storage chamber which is provided on the refrigerator body; an outlet for conveying cold air to the storage chamber; a visible light emitting type diode which is provided at a place more next to thefront edge compared with the central part in the depth direction at the upper part in the storage chamber and irradiates to the inside; a light-penetrable cover which covers the diode and is providedwith photocatalyst; and a partition which divides the space in the storage chamber and is provided with photocatalyst. The diode irradiates the cover and the partition for performing deodorization tothe cold air discharged from the outlet to the storage chamber.

Description

technical field [0001] The present invention relates to refrigerators. Background technique [0002] In recent years, as refrigerators have increased in capacity, various foods have been stored, and interest in hygiene, sterilization, and deodorization in refrigerators has increased. As a structure for sterilizing and deodorizing the inside of a refrigerator, there is known a structure in which a deodorizing filter or the like is disposed in a cool air passage to remove odor in circulating cool air. [0003] Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2003-322460) describes a structure in which an ultraviolet light emitting diode and a light deodorizing catalyst are arranged in a cool air passage. In this structure, the odor component in cool air is adsorbed on the photocatalyst, and the photocatalyst is activated by the ultraviolet rays irradiated from the ultraviolet light emitting diode. In addition, the odor adsorbed on the surface of the ...
