Next, the photocatalyst layer 20 formed on the inner wall surface in the cabinet 10 will be described.
(Photocatalyst layer 20)
The photocatalyst layer 20 is an example of a catalyst layer according to the present invention.
As illustrated in FIG. 8, the photocatalyst layer 20 is a photocatalyst coating layer formed on the inner wall surface of the cabinet body 12. The photocatalyst layer 20 is formed on the inner wall surface side of the cabinet body 12 in the left side plate 12a, the right side plate 12b, the large door 12c, the small door 12d, the bottom plate 12e, the top plate 12f, and the back plate 12g. The photocatalyst layer 20 may also be formed on the panel material 14. By forming the photocatalyst layer 20 also on the panel material 14, for example, the antifogging effect and antifouling effect of the panel material 14 can be expected.
The photocatalyst layer 20 is a photocatalyst coating layer formed by applying a photocatalytic substance, and the photocatalyst layer 20 is a layer formed by applying a titanium oxide photocatalyst. The photocatalyst layer 20 functions as a photocatalyst, for example, in a wavelength region of 0 nm to 540 nm. In addition, the photocatalyst layer 20 of this example is a layer formed of a visible light responsive photocatalyst, and functions as a photocatalyst even with fluorescent lamps arranged in an indoor environment or light from the outdoors. Therefore, the photocatalyst layer 20 functions as a photocatalyst mainly in a wavelength region of 380 nm to 540 nm. In the photocatalyst layer 20, when the light source body 38 is an LED, the wavelength region where the photocatalytic reaction becomes stronger is a wavelength region of 440 nm to 470 nm. Further, in the photocatalyst layer 20, when the light source body 38 is, for example, a fluorescent lamp or natural light, a wavelength region in which the photocatalytic reaction becomes stronger is a wavelength region of 380 nm to 400 nm. The photocatalyst layer 20 functions as a photocatalyst up to 540 nm although the photocatalytic reaction gradually decreases from the wavelength region where the photocatalytic reaction becomes strong. The photocatalyst layer 20 functions efficiently as a photocatalyst when irradiated with visible light emitted from the light source body 38. The photocatalyst function in the photocatalyst layer 20 includes, for example, an antibacterial / antifungal function, an air purification function, a deodorizing function, an antifouling function, an antifogging function, and a VOC countermeasure function. A mold effect, an air purification effect, a deodorizing effect, an antifouling effect, an antifogging effect, and a VOC countermeasure effect can be expected.

The photocatalyst layer 20 applies a photocatalyst to each member (the left side plate 12a, the right side plate 12b, the large door 12c, the small door 12d, the bottom plate 12e, the top plate 12f, and the back plate 12g) before the assembly of the cabinet body 12. The photocatalyst is applied to the inner wall surface of the cabinet body 12 that is formed or assembled. In the plant cultivation storage furniture 1 of this example, a photocatalyst is applied to each member before the cabinet body 12 is assembled, and each member on which the photocatalyst layer 20 is formed is assembled.
When the photocatalyst layer 20 is formed on the left side plate 12a made of wood, for example, among the members before assembly, the photocatalyst layer 20 is coated with a waterproofing agent on the inner wall surface side of the left side plate 12a and dried (waterproofing treatment). The photocatalyst layer 20 is formed on the left side plate 12a by applying a photocatalyst coating agent mixed with a small amount of a surfactant to the treated surface and drying it.
The photocatalyst layer 20 is coated with a small amount of a surfactant in the photocatalyst coating agent, so that the photocatalyst coating agent is applied to the application surface of the left-side plate 12a, which is waterproofed wood, without being repelled by the waterproof action. The photocatalyst layer 20 thus formed can be formed. This photocatalyst coating agent is, for example, TPX (registered trademark) -HL which is a Sagancoat (registered trademark) photocatalyst coating agent.
As described above, the photocatalyst layer 20 was originally formed only on a painted surface, cloth, diatomaceous earth / gypsum board, decorative panel, tile, or the like as a base material, but a small amount of surfactant was used as a photocatalyst coating agent. By mixing, the photocatalyst layer 20 can also be formed on the waterproofed wood.

Next, the effect | action of the plant cultivation storage furniture 1 is demonstrated.
FIG. 10 is a schematic diagram for explaining the operation of the plant cultivation storage furniture 1.
As illustrated in FIG. 10, the plant cultivation storage furniture 1 stores a rack 30 inside a cabinet 10 in which a photocatalytic layer 20 is formed. A tray 34 on which plants 50 are arranged is arranged in the stored rack body 32. The rack body 32 is provided with a light source body 38 at a position facing the tray 34. Here, the wavelengths of light effective in the photosynthesis of the plant 50 are a wavelength of 440 nm to 460 nm and a wavelength of 650 nm to 670 nm. The plant 50 is, for example, leafy vegetables (leafy vegetables), such as Japanese mustard spinach, tincture, spinach, lettuce and the like.
The plant cultivation storage furniture 1 irradiates the plant 50 with light 38 a from the light source body 38. The plant cultivation storage furniture 1 can promote photosynthesis of the plant 50 by irradiating the plant 50 with light 38 a that is visible light including a wavelength region of 440 nm to 470 nm from the light source body 38. Further, the plant cultivation storage furniture 1 can efficiently promote the photocatalytic reaction by irradiating the photocatalyst layer 20 with the light 38a from the light source body 38.
As described above, the plant cultivation storage furniture 1 irradiates the plant 50 and the photocatalyst layer 20 with visible light including the long region 440 nm to 470 nm irradiated from the light source body 38, thereby photosynthesis of the plant 50 and the photocatalyst layer 20. The catalytic function can be efficiently operated.
