PURPOSE:To enable to confirm the rotating direction of a runner by visual inspection by providing slit holes on a partition plate. CONSTITUTION:A blower casing 4 is located at the front side of a unit, a partition plate 7 is arranged at the location between an air passage inside the unit and a decorating plate, that is, a front plate which is located at the front side surface of the unit for cutting off the open air, a hole through which the rotating direction of a boss 19 or a core plate 18 can be watched at the shaft central position of a blower motor 6 and a fixing screw 9 can be fixed manually from side-plate side is provided on a casing side-plate, further, slit holes 16 are arranged in zigzag form on the partition plate so as to enable to watch the rotating direction of the runner from the partition plate side even when the partition plate is provided. Because the clearance between the partition plate 7 and the runner side-plate is small, the pressure inside of the clearance part becomes negative, only a small amount of open air comes into the inside of the clearance part even when a heat insulator open/close part is opened while the blower is driven, accordingly, a slit hole part of the partition plate is made free from frosting. |
