  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing a building 2 having a building ventilation device 1 according to the present embodiment. In addition, in this specification and drawing, about the component which has the substantially same function structure, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol. Further, the present embodiment is an exemplification for explaining the present invention, and the present invention is not limited only to the description of this embodiment.

  The building 2 in the present embodiment has, for example, a plurality of hierarchies and a flat roof 10 on the top floor. The room 11 of the building 2 has a flat ceiling surface 20. The room 11 includes rooms such as a living room and a kitchen, a hallway, a staircase, and the like.

  The ventilator 1 has, for example, an exhaust window 22 formed on the vertical outer wall 21 of the chamber 11 and a ceiling fan 23 located near the exhaust window 22 and having at least an upward air blowing function.

  The exhaust window 22 is formed, for example, in the range of 1/3 of the layer height from the upper part of the outer wall 21 of the room 11 on the top floor, for example, the ceiling surface 20. The exhaust window 22 is directed toward the downwind direction of the prevailing wind in summer. The exhaust window 22 can be opened and closed with respect to the outside of the building 2 as shown in FIG.

  The ceiling fan 23 is suspended from, for example, the ceiling surface 20 of the chamber 11, and includes a plurality of blades 30 that rotate around a vertical axis by power feeding at the lower end. For example, the ceiling fan 23 is disposed close to the exhaust window 22 as shown in FIGS. The shortest distance between the locus drawn by the tip of the blade 30 and the outer wall 21 is preferably within 80 cm, more preferably 15 cm to 50 cm, and even more preferably about 35 cm. Further, the height from the floor to the blades 30 is preferably 2 m or more, and more preferably 2.4 m or more.

  As shown in FIG. 2, the exhaust window 22 is installed such that the lower end 22 a thereof is almost the same height as the blades 30 of the ceiling fan 23. The height of the lower end 22a of the exhaust window 22 may be about 35 cm higher than the blade 30 or about 50 cm lower.

  When the ventilator 1 configured as described above is used, the exhaust window 22 is opened, and the blades 30 of the ceiling fan 23 are rotated so that an upward airflow is generated. By doing so, an upward air flow toward the exhaust window 22 is formed in the chamber 11, and the air in the chamber 11 is sucked up and effectively exhausted from the exhaust window 22.

  According to the present embodiment, the exhaust wall 22 is provided on the outer wall 21 of the chamber 11, and the ceiling fan 23 suspended from the ceiling surface 20 is provided in the vicinity of the exhaust window 22, so that a skylight or a ventilation tower is used. Compared with the case where there was, it becomes the structure which is easy and is easy to carry out rain, and can ventilate the building 2 effectively.

  Further, in the present embodiment, since the exhaust window 22 is directed toward the downwind direction of the prevailing wind in summer, exhaust from the exhaust window 22 can be promoted by negative pressure in summer when ventilation is most necessary. In addition, it is possible to suppress a decrease in exhaust efficiency due to wind blowing from the exhaust window 22.

  In the embodiment described above, the exhaust window 22 is formed at a position other than the corner of the chamber 11 on the outer wall 21, but the exhaust window 22 is formed at the corner L of the chamber 11 on the outer wall 21 as shown in FIG. It may be formed. In such a case, since the side of the ceiling fan 23 is surrounded by two adjacent outer walls 21, a narrow space is created around the ceiling fan 23, thereby forming a stronger updraft and the air in the chamber 11. The effect of sucking up can be enhanced.

  Further, the exhaust window 22 may be provided on each of the two adjacent outer walls 21a and 21b forming the corner portion L of the chamber 11 as shown in FIG. In such a case, since the two exhaust windows 22 are provided in the corner portion L where a strong airflow is formed, ventilation is performed more effectively. Further, by selectively opening and closing the exhaust window 22 according to the wind direction of the outside air, the air in the chamber 11 can be exhausted without being affected by the wind direction. In this case, the ceiling fan 23 may be arranged at an equal distance from the exhaust windows 22 of the outer walls 21a and 21b.

  In the above embodiment, the inner wall continuous to the outer wall 21 may be disposed close to the side of the ceiling fan 23 so as to surround it. Here, the “inner wall” means a wall provided in the building that does not partition the room and the exterior space of the building. For example, as shown in FIG. 6, for example, a partition wall 40 as an inner wall for partitioning between adjacent rooms may be disposed close to the ceiling fan 23. In such a case, since the side portion of the ceiling fan 23 is surrounded by the outer wall 41 and the partition wall 40, the effect of guiding the air in the chamber 11 to the exhaust window 22 can be enhanced.

  Further, the inner wall may be a side wall 45 formed by partially lowering the ceiling surface 20 of the chamber 11 as shown in FIG. Also in this case, since the side portion of the ceiling fan 23 is surrounded by the outer wall 41 and the side wall 45, the effect of guiding the air in the chamber 11 to the exhaust window 22 can be enhanced.

  Moreover, as an inner wall, as shown in FIG.8 and FIG.9, the partition plate (dripping wall) 50 surrounding the side part of the ceiling fan 23 may be sufficient. For example, as shown in FIG. 10, the partition plate 50 is suspended from the ceiling surface 20, and has a height reaching the same level as or lower than the blades 30 of the ceiling fan 23. Also in this case, since the side portion of the ceiling fan 23 is surrounded by the outer wall 21 and the partition plate 50, the effect of guiding the air in the chamber 11 to the exhaust window 22 can be enhanced. In addition, the partition plate 50 may be formed of a transparent plate. In such a case, the lighting from the exhaust window 22 can be secured.

  Both ends of the partition wall 40, the side wall 45, and the partition plate 50 may be continuous with the outer wall 21, or only one end may be continuous with the outer wall 21. Moreover, it is not always necessary to be continuous with the outer wall 21, and the partition wall 40, the side wall 45, and the partition plate 50 themselves may be discontinuous.

  Moreover, you may use combining the partition wall 40, the side wall 45, and the partition plate 50 as an inner wall, In this case, it does not ask | require continuous or discontinuous.

  The ventilator 1 in the above embodiment preferably has an air supply window 60 for introducing outside air into the chamber 11, for example, as shown in FIG. In such a case, ventilation in the chamber 11 is further promoted. The air supply window 60 is more preferably provided on the outer wall 61 substantially opposite to the outer wall 21 where the exhaust window 22 is located. In this case, the air flow in the chamber 11 becomes smooth, and ventilation of the chamber 11 is further effective. Can be done automatically.

  In addition, the air supply window 60 is preferably provided at a level lower than the level including the ceiling fan 23 as shown in FIG. In this case, the whole building can be efficiently ventilated. In a building having three or more floors, it is preferable to provide the exhaust window 22 on the uppermost floor and the air supply window 60 on the lowermost floor.

  Furthermore, the air supply window 60 is provided in a second chamber 71 different from the first chamber 70 provided with the ceiling fan 23 as shown in FIG. 14, for example, and the first chamber 70 and the second chamber 71 are provided. It is preferable to communicate with each other by a ventilation portion 80 provided on the partition wall 73 or the floor 72 between the floors. In such a case, the air in the building 2 is effectively ventilated without stagnation of the air flow from the first chamber 70 to the second chamber 71 in the building 2.

  The exhaust window 22 and the ceiling fan 23 in the above embodiment may be provided in a chamber 91 having a ceiling height of two or more levels formed by a blowout 90 as shown in FIG. 15, for example. In such a case, the ceiling fan 23 does not disturb the resident's life. The vent 90 may be provided with stairs.

  Further, the exhaust window 22 and the ceiling fan 23 may be provided in a chamber 101 having an intermediate floor 100 below as shown in FIG. 16 and having a ceiling height of about 1.5 levels. In such a case, the ceiling fan 23 does not disturb the resident's life, and the floor area can be secured.
