PURPOSE:To make temperature in hot air and cold blast larger and low noise and low-pressure loss promotable, by making a suction type air conditioner so as to ventilate a car room in a state of having the hot air and the cold blast separated by a blower case with a built-in guide which has a notch at the upstream side. CONSTITUTION:A scroll part 3A of a blower case 3 is divided into the inside and the outside with a plastic guide 40. An end part 40a at the upstream side of this guide is situated in a position being dislocated as far as just 180 deg. from that of a nose 3C of the scroll, and a V-shaped notch 40c is installed there. Length of this notch 40c is set to half of length l of the guide 40. With this constitution, if a part of hot air and cold blast being led into the inside of the blower case 3 is mixed each other, most of them are guided as being left divided intact, and when a supply opening select damper 22 comes to 22b with a by-level mode, the hot air is led into a down blast passage 23 while the cold blast into an outlet 20 respectively so that a temperature difference is made enough distinguishable to the blowoff temperature, thus comfortable temperature distribution, say, keeping the head cool and the feet warm, is securable. |
