Problems solved by technology

[0035] 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.
[0036] 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.
[0037] 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.
[0038] 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.

Embodiment approach 1

[0193] Figure 7 It is a front view of the refrigerator in Embodiment 1 of this invention.

[0194] As shown in the figure, refrigerator 100 according to the present embodiment is refrigerator 100 having a door of a split type, and has a store room divided up and down in heat insulating box 101 .

[0195] Store rooms divided up and down in refrigerator 100 are called refrigerator room 102 and freezer room 103 according to their functions (cooling temperature).

[0196] In the front opening of the refrigerator compartment 102, a rotary heat insulating door 107 is provided as a door body filled with a foam heat insulating material such as urethane. In addition, insulated door 107 is also provided in front of freezer compartment 103 in the same manner. Thereby, the store room is sealed openably and closably so that cool air does not leak.

[0197] Refrigerator room 102 is a storage room maintained at a low temperature such that it does not freeze for refrigerated storage. As ...

Embodiment approach 2

[0287] Next, other embodiments will be described. In addition, the same reference numerals are assigned to the same configurations as those in the first embodiment described above, and description thereof will be omitted.

[0288] Figure 15 It is a longitudinal sectional view which schematically shows the refrigerator of this embodiment.

[0289] As shown in the figure, the sterilization device 200 and the lighting mechanism 300 are attached to the ceiling of the heat insulation box 101 . In addition, the sterilization device 200 and the lighting mechanism 300 will be described later.

[0290] Figure 16 It is a cross-sectional view showing the sterilization device and the lighting mechanism in the state attached to the refrigerator.

[0291] Figure 17 It is a bottom view showing the sterilization device and the lighting mechanism in the state attached to the refrigerator.

[0292] The illuminating mechanism 300 is a device for illuminating the inside of the heat insul...

Embodiment approach 3

[0318] Figure 20 It is a longitudinal sectional view of the refrigerator of this invention.

[0319] Figure 21 It is a front view which shows the structure of the flow path forming mechanism of the refrigerator of this invention.

[0320] In these figures, for example, an insulated box 101 constructed by insulating the surroundings with a heat-insulating material such as rigid foamed urethane is divided into a plurality of sections, and a refrigerator compartment 102 is arranged in the uppermost part, and a refrigerator compartment 102 is arranged in the lowermost part. The freezer compartment 103 is the first storage compartment, and the vegetable compartment 104 as the second storage compartment is arranged directly above the freezer compartment 103, and the ice-making compartment as the third storage compartment is arranged side by side between the vegetable compartment 104 and the refrigerator compartment 102. Room 105 and a switching room 106 as the fourth storage roo...

Abstract

Provided is a refrigerator (100) comprising an insulating box constituted of an insulating material and forming storage chambers therein, doors attached openably / closably to the openings of the insulating box, cooling means for cooling the air in the insulating box to generate cold air, and a cold air circulating passage for circulating the cold air between the storage chambers and the cooling means. The cold air circulating passage includes a carrier for carrying a photocatalyst, an irradiation means for irradiating the carrier with exciting light for exciting the photocatalyst; and an air blowing mechanism for forcibly blowing the cold air to the carrier.

Description

[0001] This case is a divisional application of the patent application with the application number 200880012877.5 and the invention name is refrigerator and sterilization device technical field [0002] 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 [0003] 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 system. [0004] figure 1 It is a figure showing the refrigerator which took off an insulation part from the back model. [0005] As shown in the figure, in refrig...
