  The present invention relates to a refrigerator having an antibacterial function in a refrigerator.

  In recent years, antibacterial and antifungal properties of foods have not been sufficient in low-temperature storage in refrigerators. In the environment in the refrigerator, the growth rate of bacteria and mold is reduced, but the growth is not stopped. For this reason, a specification in which various volatile antibacterial materials are kneaded into a resin is generally known (see, for example, Patent Document 1).

  Hereinafter, the conventional refrigerator will be described with reference to the drawings.

FIG. 6 is a schematic cross-sectional view of a conventional refrigerator. In the figure, 1 is a volatile antibacterial agent diffusion component, 2 is a freezing room, 3 is a refrigeration room, 4 is a vegetable room, 5 is a blower, 6 is a cooler, 7 is a cold air passage, and 8 is a refrigeration room outlet. By the said structure, it becomes the specification by which a volatile antibacterial substance is diffused in a refrigerator cabinet.

Accordingly, it is possible to provide a long-life volatile antibacterial agent-dispersing part, and to provide a refrigerator that does not require replacement of components during the period of use of the refrigerator.

  The invention according to claim 3 is the invention according to claim 1, wherein the volatile antibacterial agent releasing member has a low emission gel-like content of the volatile antibacterial agent, and the volatile antibacterial agent is released. By optimizing the amount, it is possible to provide a volatile antibacterial agent-dispersing part having a long life specification, and it is possible to provide a refrigerator that does not require any member replacement during the period of use of the refrigerator.

  The invention according to claim 4 is the invention according to claim 1, wherein the volatile antibacterial agent diffusing member has an outer member using a low gas permeable material, and the volatile antibacterial member from the outer member. By suppressing the leakage of the agent, it is possible to provide a volatile antibacterial agent-dispersing part having a long life specification, and provide a refrigerator that does not require any member replacement during the period of use of the refrigerator.

  According to a fifth aspect of the invention, in the first aspect of the invention, the volatile antibacterial agent diffusing member has an outer member made of an aluminum laminate film material having no gas permeability, and volatilization from the outer member. By blocking the leakage of the functional antibacterial agent, it is possible to apply a volatile antibacterial agent-dispersing part with a long life specification, and to provide a refrigerator that does not require member replacement during the use of the refrigerator.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments.

FIG. 1 is a schematic sectional view of a refrigerator according to Embodiment 1 of the present invention. FIG. 2 is an enlarged cross-sectional view of a portion A in FIG. Reference numeral 7 denotes a cold air passage. 9 is a volatile antibacterial agent diffusion member, and 10 is antibacterial component particles. 11 is a low gas permeable sustained release membrane, 12 is a gel-like content impregnated with the antibacterial component particles, and 15 is an outer member. FIG. 3 is a cross-sectional view of the sustained-release membrane of the refrigerator according to Embodiment 1 of the present invention.

  In the above-described configuration, the amount of isocyanate released as a volatile antibacterial agent is controlled by increasing the thickness of the low gas-permeable sustained-release film 11 to about 1.5 times with a polypropylene thin film, thereby providing a predetermined amount of isocyanate ester released. 1 to 10 μl / cm 2 · h (under an atmosphere of 5 ° C.) can be maintained for about 10 years, and a refrigerator that does not require member replacement during the use of the refrigerator can be provided.
