Abstract
PURPOSE:To decrease noise in an electric motor-driven blower and to enhance its effect of blowing air by providing an extension part in a flat path of a diffuser in an air guide and forming a space part between this extension part and a tilt path. CONSTITUTION:A stream of air, fed from a centrifugal type impeller 24 driven by a motor 31, is guided by an air guide 25. The air guide 25 provides an extension part 34, which extends in the direction of a tilt path 27, in a flat path 26 of a diffuser 28. A blower forms a space part 35 between this extension part 34 and the tilt path 27. Even when the stream of air is allowed to flow such as the arrow head of a dotted line, one part of the stream of air is sucked into the space part 35 because of a pressure difference, and in this way, the blower, changing the whole flow of the stream of air into the downward direction, allows the stream of air to easily flow along the tilt path 27. In this way, efficiency of the blower is substantially improved.
