PURPOSE:To contrive to enable the exhausting of air without hindrance even when a shielding such as a building wall and the like is located at adjacent position by a method wherein both side-walls of an exhausting passage are opened as inclined along with a rain line penetration angle backward from an upper wall end part of both side parts. CONSTITUTION:An intake and exhaust duct 11 is formed by both side-walls 12, 13, an upper wall 14, a lower wall 15 and an intermediate partition plate 16, while the upper passage is used for an exhausting passage 17, the lower passage is used for an intaking passage 18, a suitable width eave 19 directed nearly downward is provided at the end part of the upper wall 14 of an upper side exhausting passage 17. Both side-walls 12, 13 of the exhaust passage 17 are inclined backward along a rain line penetration angle from the both side parts of the end part of the upper wall 14, then exhausting ports are opened toward front and both sides. Intaking open air is introduced through an intake port 10 opened downward same as conventional, with exhaust air exhausted toward front and both sides direction of the exhausting passage 17 as shown by arrow marks. Therefore, the exhausting can be performed without hindrance even when a shielding such as a building wall and the like is located in adjacent position. |
