The present invention relates to an exhaust gas inflow prevention structure for an entrance door, which is installed in a crew accommodation space or around an entrance door of a sailing room. A wind deflector is installed around the entrance door. The wind deflector installed around the entrance door comprises horizontal and vertical boards, which are open toward the stem and closed toward the stern. The horizontal board of the wind deflector has a trapezoidal shape from a plane angle. The wind deflector installed around the entrance door is installed to be opposite to both entrance doors of the sailing room based on the longitudinal direction of the ship. Accordingly, the exhaust gas backflow prevention structure for an entrance door of a ship according to an embodiment of the present invention can block the exhaust gas flowing backward from a chimney by using the wind deflector installed around the entrance door of the sailing room of a superstructure on a ship in order to form an air pocket, thereby securing the health of crew and safe working spaces. Also, according to the present invention, steel materials for enclosing an entire bridge wing can be replaced with a lightweight structure shaped as a tiny open shelter. In addition, various kinds of equipment, which are used to add an air conditioning system and to enclose a bridge wing, do not need to be equipped, so the cost of production can be reduced. |
