Refrigerator, and disinfecting device

Abstract

In order to efficiently deodorize and sterilize an inside of a refrigerator, the refrigerator includes a heat-insulating main body which is made of a heat-insulating material and in which a storage compartment is formed, a door attached to an opening provided on the heat-insulating main body so as to be openable and closable, and a cooling unit which cools air inside the heat-insulating main body,and the refrigerator includes: a support which is placed in the storage compartment and on which a photocatalyst is supported; an irradiation unit which irradiates the support with excitation light which excites the photocatalyst; and an air blowing unit which forcibly blows the cool air inside the storage compartment toward the support.

Description

technical field [0001] The invention relates to a refrigerator for directly or indirectly cooling a storage room, in particular to a refrigerator and a sterilization device capable of degerming and deodorizing the storage room. Background technique [0002] Conventionally, in small refrigerators or refrigerators used in dry regions such as Europe, the countermeasures against dew condensation in the storage room are not very important, so the direct cooling method that cools the air in the storage room with cooling panels or the like is generally adopted. For example, Patent Document 1 discloses a refrigerator employing a direct cooling method. [0003] figure 1 It is a figure showing the refrigerator which took off an insulation part from the back model. [0004] As shown in the figure, in refrigerator 100 , cooling pipes 21 are arranged in a meandering manner on the inner side of the back wall of the store room. And, in the inside of the cooling pipe 21, the liquid refri...

Problems solved by technology

[0034] However, in the case of a direct cooling type refrigerator, for example, the air cooled on the back side of the storage room has a high density and stagnates in the lower part of the storage room, causing temperature unevenness in the vertical direction of the storage room.

In particular, when a shelf that partitions the storage room up and down is installed and food, etc. are loaded, the temperature unevenness in the storage room becomes remarkable.

[0035] In addition, due to the stagnation of air in the storage room, there is a problem that bacteria, mold, etc. multiply locally in high concentrations.

[0036] In addition, there are proposals to use organic volatile antimicrobial agents as countermeasures against the above-mentioned bacteria and molds, but the amount of evaporation of antibacterial agents is limited

Therefore, it is necessary to periodically replace the antibacterial agent, which takes time

In addition, in a refrigerator with poor convection in the storage room, the antibacterial agent will remain in a part of the storage room, and the effect of sterilization on the entire storage room cannot be achieved.

In addition, the use of organic antimicrobial agents in storage rooms for food preservation has its own problems.

[0037] In addition, a cooling pipe is arranged on the back side of the storage room, and a sheet containing an organic volatile antimicrobial agent is placed so as to roughly cover the ceiling of the storage room, so it may be difficult to select a position for installing a lighting mechanism that illuminates the storage room.
