<p>A range hood (10), comprising a hood body (11) installed on an indoor wall (30) to discharge air including lampblack and vapor produced by cooking on a galley (40) or exhaust gas to the outside, a hood (12) opening at the lower end of the hood body (11) to take in the exhaust gas, and an exhaust fan (13) assembled in the hood body (11) and having an outlet connected to an exhaust duct (20) opened to the outside, wherein a bypass passage (14) for the air including lampblack or exhaust gas is formed in the hood body (11) at the rear of the exhaust fan (13), one end of the bypass passage (14) is allowed to communicate with an outlet (13b) of the exhaust fan (13), the other end of the bypass passage (14) is opened to the wall (30) side of the hood, and an electric fan (18) is installed at the other end of the bypass passage (14), whereby not only the air including vapor or exhaust gas can be surely discharged to the outside but also the air or exhaust gas can be sufficiently led into the hood supplementing the shortage of updraft, adherence of oil contamination onto the surface of the indoor wall can be suppressed, and air supply can be sufficiently performed even in a kitchen with high sealability.</p> |
