Description

  The present invention relates to an intake / exhaust device in an indoor space where odor is likely to be generated in a room using a toilet of a housing complex or a portable toilet and requires ventilation.

  Conventionally, toilets in apartment buildings that require ventilation are often shielded from the outside, and in narrow rooms, many are ventilated from the ceiling by the activation of a ventilation fan installed in the ceiling.

  In addition, some intake and exhaust pipes with a rectangular cross-sectional shape were installed on the ceiling and floor sides along the wall surface of the room, and were naturally ventilated through the duct on the back of the ceiling.

  In addition, in a bathroom or the like, air is circulated by a ventilation fan installed on the ceiling surface with a louver attached to the lower side of the door in order to discharge the generated steam.

  However, in a highly sealed room, especially in toilets, where contaminated air and chlorine-based odors are relatively heavy and tend to accumulate in the lower part near the floor, ventilation can be achieved only by starting the ventilation fan installed on the ceiling. It took time to.

  In addition, when removing the odor and polluted air by natural ventilation from the intake port provided on the floor side by installing a rectangular intake and exhaust pipe in the vertical direction from the floor side to the ceiling side on the indoor wall surface, In a limited space, the intake / exhaust pipe protrudes to the indoor side, and the limited space becomes even narrower. Also, not only the position of the intake / exhaust port but also the installation mode differs depending on the purpose of use in the room, for example, the toilet and living room In each case, specifications corresponding to different indoor spaces were required.

  An object of the present invention is to integrate a suction / exhaust pipe installed in a vertical direction on a wall surface and a ventilation fan installed in a ceiling portion to make a flat rectangular intake / exhaust pipe compact and thin, thereby requiring ventilation. The present invention provides a building intake / exhaust device that aims to maintain efficiency and to make effective use by minimizing protrusion in an indoor space.

  In order to achieve the above object, the building intake and exhaust apparatus according to the present invention is configured such that a flat rectangular intake and exhaust pipe is attached in a vertical direction between a ceiling surface and a floor surface along an indoor wall surface, at least on the floor surface side. An air inlet is provided, and the inside forms a hollow opening with an air passage, and the intake and exhaust pipes are connected to a ventilation fan installed on the ceiling via a joint part at the upper end, and when the ventilation fan starts, It is characterized by forcibly sucking in stagnant odor or polluted air from the intake port and discharging it to the outside through the cavity port formed in the flat rectangular intake and exhaust pipe and the intake and exhaust port of the ventilation fan. is there.

  Furthermore, the flat rectangular intake / exhaust pipe is attached in the vertical direction between the ceiling surface and the floor surface between two adjacent rafters with a thickness equal to or less than the thickness of the rafter supporting the wall plate. It is characterized by being housed on the inner surface side of a wall plate or wall finishing material.

  Further, the flat rectangular intake / exhaust pipe is formed on the wall surface, and the joint portion is substantially the same shape as the flat rectangular intake / exhaust pipe, and is exposed to the ceiling surface and connected to the ventilation opening of the ventilating fan. It is what.

  Further, the flat rectangular intake / exhaust pipe is installed in a corner portion of the room.

  According to the building intake / exhaust device according to the present invention having the above-described configuration, a flat rectangular intake / exhaust pipe extending vertically between the ceiling surface and the floor surface and a ventilation fan installed on the ceiling portion are provided. Odor, polluted air or water vapor stays on the floor side of the room by the air intake vents drilled on the floor side of the flat rectangular intake and exhaust pipe using the forced ventilation function of the ventilation fan. And the like can be forcibly and effectively sucked and can be easily discharged to the outside through a cavity port formed in a flat rectangular intake and exhaust pipe and an intake and exhaust port of a ventilation fan.

  In addition, because the forced ventilation function of the ventilation fan is used, the odor and air pollution that tends to stay on the floor side can be removed in a short time from the air inlet provided on the floor side of the flat rectangular intake and exhaust pipe. The room can be kept clean by removing odors and odors from living spaces such as sick people, bedridden elderly people, pets, etc.

  Further, the intake / exhaust pipe is formed in a flat rectangular shape in conjunction with the ventilation fan, and the thickness thereof is equal to or less than the thickness of the rafter supporting the wall plate, and is attached between two adjacent rafters. By being stored on the inner surface side of the finishing material and mounted vertically between the ceiling surface and the floor surface, it can be mounted without exposing it to the wall surface while maintaining ventilation efficiency, and in a limited space such as a toilet Effective use is made and its beauty is not impaired.

  In addition, the intake and exhaust pipes are flat rectangular on the wall surface, and the joints are exposed to the ceiling surface in the same shape as the flat rectangular intake and exhaust pipes, and are connected to the ventilation opening of the ventilation fan so that they are continuous. Installation work can be done very easily without remodeling the surface, and the length of the distance between the ventilation fan and the flat rectangular intake and exhaust pipe, or the height, etc., can be adjusted easily at the site work stage. be able to.

  Further, by installing the flat rectangular intake / exhaust pipe at a corner portion in the room, the dead space in the room can be used effectively.

The best mode of the present invention will be described below with reference to the accompanying drawings.
