ある。Conventionally, the double-suction type multi-blade blower is constructed as shown in FIG. 3, and has only one ventilation passage. (1) is an impeller, which is composed of a main plate (main plate), annular side plates (3a), (3b), and 84ti (4). (5) is a spiral casing with an air outlet (6) and side plates (7a) (7b).
) and has nine suction ports (8a) (8b). (
9) is a motor for driving the impeller (1), which is fixed, for example, to the casing (5), and whose rotary shaft is connected to the center of the main plate (2) via a hub (B). Since the conventional blower is constructed in this way, when the motor (9) is rotated, air is sucked in from the suction ports (8a) and (8b) as shown by the arrows M and M', and the impeller (1) is It passes through and is sent to the air outlet (6). In this case, the airflow from the impeller (1) to the outlet (6) is
), so if such a multi-air blower is used in a blowing mechanism that requires two independent ventilation paths, another blower will be required. As a result, the blower system may become more complex, requiring more man-hours to assemble the blower system due to the need for two blowers, and increasing the cost of the mechanism. Furthermore, there are various disadvantages of increasing the size of the KFi mechanism.
