[0013]

As described in detail above, according to the osseous chamber ventilation system according to the present invention, the outside air suction type fan unit having high immediate effect is driven by the electric energy generated by the daytime solar cell panel. This makes it possible to efficiently introduce fresh, low-humidity outside air and maintain the environment and atmosphere of the osseous chamber to the temperature and humidity of the outside air, resulting in dew condensation on the urn, formation of mold in the osseous chamber, and insects. It is possible to effectively suppress the inhabitation of species. As a result, the inside of the osseous chamber can always be kept clean,
It is possible to maintain a space suitable for encasing a sacred urn for a long period of time without requiring any cleaning or the like even in the case of a law every several years. In particular, in the present invention, the adoption of the external air suction type fan unit enables efficient intake and exhaust, so that the dehumidification has a high immediate effect, and a direct storage from a solar cell panel is possible without providing a storage battery or the like. Effective ventilation is possible even with only power supply,
Moreover, because the fan unit that is driven only when it receives power from the solar cell panel is designed to constantly ventilate, the structure is simplified by omitting the intervention of the humidity sensor etc. and the control accompanying it. As a result, reliable ventilation was achieved without fear of malfunction. Furthermore, if check valves are installed in the intake duct and the exhaust duct, each check valve will be automatically operated by its own weight even if sufficient power cannot be obtained in cloudy weather or sunlight when the sunlight is weak. It is possible to maintain a low humidity environment secured by the operation of the fan motor for a long time by closing the fan motor to a simple structure according to the present invention without the need for a storage battery or the like even during intermittent power supply in bad weather. It will play a more effective role in achieving this. Further, each of the above-mentioned check valves can also serve as a measure for avoiding rain entering from the outside of the duct, which is extremely useful. Also, if the grave is in a place where household power can be connected, it is possible to connect a household power circuit instead of or in addition to the power circuit from the solar panel. The person can choose either power source, and the added value as a product will increase.
