Description

Technical Field

[0001] The present invention is an underground apartment where the room layout can be not only 3DK but also 2DK etc., and can be expanded horizontally and the number of floors can be increased up to 40M as well. There is no change in the intake and exhaust ducts, and the dehumidifier can be moved to a place with power supply.

Background Art

[0002] In each room of the underground apartment, intake and exhaust are carried out at a ratio of 1:1. In the underground apartment, in order to avoid the risk of oxygen deficiency, a device with speed control is used, and the indoor ventilation fan installed indoors can also be constantly used for carbon dioxide emission.

[0003] Regarding the wall thickness of the underground apartment of the present invention, the outer wall is 400 mm, the floor of the lowest floor is 400 mm, and the thickness of the ceiling of the top floor is 400 mm. Moreover, 600 mm of soil is further covered on the GL above it. However, the adjacent boundary wall thickness inside the underground apartment is within the building standard range.

[0004] Soundproof doors are used for the doors of the underground apartment, and glass doors are used for intake and exhaust. For safety reasons, they are used with the glass doors open. The doors are 900 mm wide and 1900 mm high, while the glass doors are 300 mm.

[0005] The round shape of the intake and exhaust device is 100 mm, and one fan is attached and operated every 500 mm inside the intake duct. However, it is installed within that range in places with sharp curves.

[0006] The wall beside the entrance uses an intercom camera with an alarm display.

[0007] The flow of fresh air is taken in from the shed on the rooftop GL, exhausted from the front of the entrance, and discharged from the shed for GL discharge.

[0008] Small windows for intake are also installed.

Summary of the Invention

Problems to be Solved by the Invention

[0010] According to Japanese Patent No. 5327401, it is a ventilation system in a shelter composed of a pretreatment filter and a main filter section, and it is described as a ventilation system characterized by having a crank section for manually driving a fan when an electric drive motor cannot be used. However, the present invention is a system that always installs solar power generation on the GL, charges a storage battery, and can be used at any time. Conventionally, there is a multi-purpose disaster prevention and defense facility characterized in that the thickness of the concrete on the top, side, and bottom of a building is 50 meters or more. However, a building with such a concrete thickness is impossible and does not exist. The present invention makes use of the characteristics of an underground condominium and uses a thickness such as in the technical field so as to withstand a direct underground earthquake and not be exposed to the threat of radioactivity. An underground condominium equivalent to a 10-story building constructed underground, the depth of the underground condominium is up to 40 m and the number of floors is 10 floors underground. There is at least a living room section underground, and a duct fan for sucking, exhausting, and discarding air in the classroom section. The air of the intake duct fan is supplied to the living room section, and after circulating through the living room section, a duct fan is provided in the duct so as to be discharged outdoors from the exhaust duct fan.

[0011] The underground condominium can take measures against air pollution and radiation, remove dust, yellow sand, etc. floating in the air such as pm2.5 and pm10, and is equipped with a dehumidifier for mold prevention. The underground condominium automatically removes carbon dioxide discharged from the human body. Since air accounts for 83% by weight, which is the largest intake amount of the human body, the normally operating duct fan operates in conjunction with an air purifier.

[0012] The underground apartment has a structure with few opening and closing parts and is equipped with a device for playing classical music via Internet radio at any time for relaxation. The underground apartment has solar power generation installed on the ground to operate a constant power generation system, constantly ensuring power supply to a storage battery facility to support the power supply for elevators and some lighting fixtures. The underground apartment is equipped with a Geiger counter for measuring residual radiation in case of an emergency. The underground apartment is equipped with a storage for canned grains, vegetables, and fruits at all times so that residents can live in peace when they cannot go outside.

Means for Solving the Problems

[0013] An underground apartment equivalent to a 10-story building constructed underground, with the depth of the underground apartment reaching up to 40 m and the number of floors being 10 basement floors. Underground, there is at least a living room area, and a duct fan for sucking in, exhausting, and discarding air in the classroom area. A duct fan is provided in the duct so that the air from the intake duct fan is supplied to the living room area, circulated in the living room area, and then discharged outdoors from the exhaust duct fan.

Effects of the Invention

[0014] It is difficult to block radiation only by the thickness of concrete. There are multiple types of radiation, such as alpha rays, beta rays, gamma rays, and X-rays. Alpha rays can be blocked by paper or aluminum, beta rays can be blocked by a thin acrylic plate, and gamma rays and X-rays are blocked by lead plates or thick concrete, etc. Since the underground apartment has a structure that can withstand a direct underground earthquake, the safety of the underground apartment can be enhanced by using a mesh filter that can adsorb and remove radioactive substances.

[0015] The major problem is a direct-hit earthquake. When such an earthquake occurs, what people worry about most are the nuclear power plants installed in the country. However, it is said that it is extremely difficult to stop or maintain the nuclear reaction in a fusion reactor under development, unlike a fission reaction. If a direct-hit earthquake is certain to occur in the near future, it is a highly safe underground condominium that will inform about the fusion reactor that is attempting to operate in the first half of the 22nd century.

Modes for Carrying Out the Invention

[0017] The present invention focuses on air purification and carbon dioxide emission in an underground condominium with a ducted fan, and has a mechanism to operate constantly and safely even during a power outage. However, even if there is carbon dioxide emission or radioactive leakage in an emergency, a mesh filter that can adsorb and remove radioactive substances until the half-life comes is used.

[0018] [Details of Figure 1] It is a room in an underground condominium. The structure of the room can be increased horizontally and vertically within the scope of the Building Standards Law. Similar to a general residence, there is a Japanese-style room and a Western-style room, and there are a kitchen set, a bathtub, a place for a washing machine, and a toilet and entrance. 1-It is an overall view of the room.
