Abstract

PURPOSE: To improve a performance of blower suction by a method wherein the suction port is eccentrically positioned at a part having a high suction force at the inner diameter enclosing line in a range of a specified angle from a centre of the multi-vane fan.
CONSTITUTION: As shown in the dawing, the suction port 3 is positioned eccentrically from the center of the multi-vane fan 22. That is, the suction port 3 is positioned eccentrically at a place of about 120° in a rotational direction of the main body of the multi-vane fan 22 toward the inner diameter enclosing line of the vane. In this way, it is possible to improve a performance of suction of the blower by a provision of the blower in which the suction port 3 is eccentrically arranged toward the vane inner diameter enclosing line having a high suction force from a center of the mult-vane fan body 22 in a range of specified angle in a rotational direction of the multi-vane fan 22, starting from the nose 23 in the casing.
