Deodorization module and storage device including deodorization module

A sterilization module comprising:

• a housing including a bar fixed member and a substrate fixed member, and formed of a reflective material, wherein each of the bar fixed member and the substrate fixed member protrudes inward from an inner side surface of the housing and has a groove;
• a photocatalyst bar disposed such that air introduced into the housing passes through the photocatalyst bar;
• a light source module including a light source substrate and at least one ultraviolet (UV) light source on a first surface of the light source substrate, the light source module configured to emit light toward the photocatalyst bar;
• and
• an external guide protruding outward around an outer periphery of the housing,
• wherein the photocatalyst bar is secured in the housing by inserting a side surface of the photocatalyst bar into the groove of the bar fixed member,
• wherein side surfaces of the photocatalyst bar contact inner side surfaces of the housing, respectively,
• wherein the light source module is secured in the housing by inserting at least of a region of the light source substrate into the groove of the substrate fixed member,
• wherein the sterilization module is secured in an external component providing an external space of the housing by the external guide,
• wherein the external guide is of a shape so as to enable only a first region of the sterilization module to be exposed to an external space of the housing and a second region of the sterilization module to not be exposed to an external space of the housing,
• wherein the external guide is fitted around the outer periphery of the housing so as to be substantially parallel to an upper surface and a lower surface of the housing, and
• wherein an amount of the sterilization module that is not exposed to an external space of the housing is determined based on a distance from a lower surface of the sterilization module that the external guide is fitted around the outer periphery of the housing, to the external guide.
