{Experimental result}
Comparative Example 1 was produced in addition to Example 1 of the present invention described above, and the heat shielding effect was measured. Comparative Example 1 is the same size as Example 1, with no outer panel, ducts, fans, vents, AED housed in a sealed box with only a single body wall and a single door. This is an outdoor type AED storage box device. Although there is a window in which the AED can be seen in the main body of the comparative example, no heat shielding film is attached to the window. Example 1 and Comparative Example 1 were installed in a laboratory room temperature of 40 ° C., both were irradiated with simulated sunlight under the same conditions, and the temperature change of each part was measured.

  FIG. 10 is a schematic view showing a temperature measurement site. In FIG. 10, the outer panels other than the front surface are omitted. Moreover, FIG. 11 is a figure which shows the temperature measurement result in each part of the Example and comparative example of this invention. In FIG. 10, the results of measurement at the circled 1, that is, the location indicated as No. 1 are indicated as AED in FIGS. 11 to 13. No. is outside the door, No. 4 is a light shielding plate, and No. 8 is room temperature. The results measured with the outdoor type AED storage box device of Example 1 are shown as outdoor type in FIGS. 11 to 13 and the result of Comparative Example 1 is shown as indoor type. 11 to 13, the horizontal axis indicates the pseudo-sunlight irradiation time, and the vertical axis indicates the temperature at the measurement location. In order to clearly show the effect of each air convection, in Example 1, for the sake of convenience, measurement was performed with all fans stopped for 0 minutes to 45 minutes after the start of irradiation, and the lower fans were operated for 45 minutes to 78 minutes. The measurement was performed for 78 minutes to 111 minutes by operating the lower and central fans. In FIG. 11, portions where there is a sudden change in the data of Example 1 after 45 minutes and after 78 minutes from the start of irradiation are for changing the conditions.

  FIG. 12 is a diagram showing the temperature measurement results of the front part of the AED of the example of the present invention and the comparative example. In Comparative Example 1 (indoor type) which has no double structure and no fan, the temperature in front of the AED rises after the start of irradiation and becomes a high temperature exceeding 60 ° C. Therefore, there is a high risk that the AED will be in a high temperature state, causing failure or deterioration, and will not operate correctly when trying to use it, and there is a risk that the life of a saved patient cannot be saved if it operates correctly. On the other hand, in Example 1 (outdoor type), the temperature rise was moderate and was about 42 ° C. even when the temperature exceeded 60 ° C. in Comparative Example 1. From the data of 0 minutes to 45 minutes after the start of irradiation, it can be seen that the temperature rise is reduced in Example 1 due to air convection due to the double structure as compared with Comparative Example 1. In Comparative Example 1, the temperature continued to rise gradually after that, exceeding 65 ° C. However, from the data for 45 minutes to 78 minutes and the data for 78 minutes to 111 minutes after the start of irradiation, the temperature rise is suppressed in Example 1 due to the air convection by the fan compared to Comparative Example 1, and even the lower fan alone is used. It was found that the temperature could be 45 ° C. or lower, and the temperature rise was significantly suppressed. Furthermore, in Example 1, since the center fan also operates, the temperature further decreased by 1, 2 ° C., and in Example 1, it was found that the temperature increase was efficiently suppressed. In Comparative Example 1, which has a single structure and has neither a fan nor a heat-shielding film, the internal temperature rises drastically when exposed to sunlight, which may have a serious adverse effect on the AED. By combining convection with air convection from the lower and center fans, and applying a thermal barrier film to the window on the outer panel, the front of the AED inside the outdoor AED storage box device can be exposed to sunlight. It has been found that the temperature of can be maintained at a level that is almost the same as the ambient temperature. FIG. 13 is a diagram showing a temperature measurement result on the outside of the outdoor type AED storage box device of the example of the present invention and the comparative example. In FIG. 13, since Comparative Example 1 has a single structure, the data outside the door is the outside temperature of the entire apparatus. In Example 1, the data of the light shielding plate is outside the outside panel, that is, the outside temperature of the entire apparatus. It is. In both the single structure and the double structure, the outside temperature of the entire apparatus rises to 60 ° C., but in Example 1, it was found that the outside temperature of the entire apparatus was lowered by about 5 ° C. due to air convection by the fan. In addition, from the data of the inner part of the double structure of Example 1 in FIG. 11, that is, the outdoor type outside door data, in Example 1, the body outside temperature is 46 ° C. due to the double structure. It was found that the temperature rise was suppressed to the extent that the temperature rise was further suppressed to a difference of about 2 ° C. from room temperature due to the presence of the fan.

  According to the first embodiment of the present invention, the radiant heat due to sunlight is prevented from being directly transmitted to the main body by shielding and heat-shielding the outer panel, and the main body is provided by one or more exhaust means provided on the main body. The internal heat can be released and hot air convection can be caused by the air convection layer between the double structures to suppress the temperature rise inside the main body. By these synergistic effects, it is possible to prevent the temperature inside the box storing the AED from rising excessively and to realize an outdoor type AED storage box device suitable for outdoor installation. According to the first embodiment of the present invention, the outer panel and the main body are provided with a window portion that allows the AED to be visually recognized from the outside, and the heat shield film is provided with the radiant heat and the sun's direct sunlight entering the outer panel window portion. By blocking with, the temperature rise of the AED can be prevented without impairing the visibility of the AED. In addition, according to the present embodiment, rainwater and snow that may enter the inside of the main body from the opening of the duct below the front side of the main body due to a gap between the outer panel and the main body is discharged by the drainage means. Therefore, even if it is exposed to wind and rain or snow, water does not collect inside the main body, which is suitable for outdoor installation.

  The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the invention. In addition, the constituent elements of the above embodiments can be arbitrarily combined without departing from the spirit of the invention. For example, in the present embodiment described above, it is a rectangular parallelepiped outdoor type AED storage box device, but it may be cylindrical and may have any shape as long as it has a double wall structure.
