An electric vacuum cleaner is equipped with a dust collection unit () that can be detachably installed in the air passage en route from a suction unit to an electric fan of the cleaner. The dust collection unit () comprises a dust collecting case () for accumulating dust sucked in, a lid member () that can be opened to discharge the accumulated dust; and a lock mechanism (clamp lever) () for locking the lid membertightly closed. The dust collection unit () is further provided with a hand grip (), arranged to face said user, thereby facilitating a user to hold the dust collection unit when discharging dust from the bottom of the dust collecting case. Further, a hinge () is arranged at a position which is adjacent to said bottom () of said dust collecting case () facing the user holding the hand grip. Furthermore, a lock mechanism () is arranged near the periphery of the lid member () and at a position opposite to the hinge.

The electric vacuum cleaner is further provided with a lid opening mechanism (lid opening stick () for forcibly opening the lid member () in cooperation with the lock mechanism locking the lid member. Even when the sealing pressure of the packing is high or when the accumulated dust does not weigh on the lid member because the dust is compacted on the inner wall of the dust collecting case, the lid member can be opened without difficulty to discharge the dust, without opening it by hand. Thus, the user can avoid handling unsanitary dust.

In an electric blower, exhaust air discharged radially from a centrifugal fan is redirected to a motor drive section by a diffuser and a fan cover. The air passes from a ventilation opening on a motor frame and through a bracket to cool the motor drive section. A portion of the air from the centrifugal fan is bled off through exhaust openings without passing over the motor, whereby this portion remains cooler and cleaner than the air that passes over the motor. Air flows up a wand and then passes over the motor to cool the motor. This air passes through filters before being discharged. The portion of air that is bled off passes along a parallel path in the wand to agitate dirt, and to maintain the wand relatively cool. In one embodiment, some of the bled-off portion is discharged directly without passing along the wand.
