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.

Dust collection unit for electric vacuum cleaner and upright electric vacuum cleaner

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 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.

Electric vacuum cleaner equipped with a dust collection unit

An upright vacuum cleaner includes a secure handle on an upper part of a dust collecting portion. The handle may be used for transporting both the dust collection portion and the upright vacuum cleaner. The handle allows simplified construction, reduced costs, and increased user safety. An attachment mechanism provides secure double locking protection against accidental separation without simultaneous two-part operation and has a latching hook and a locking part which positively engage the dust collection portion and the vacuum cleaner body.

Upright type electric vacuum cleaner

A dust-collecting device for a vacuum cleaner comprising a dust-collecting case which is fitted into a suction path extending from a suction nozzle to a motor fan and from which accumulated dust can be discharged by opening a bottom lid of the dust-collecting case, and a cylindrical filter fitted into the dust-collecting case. The filter is arranged to be rotatable, a spiral rib is formed at an outer periphery of the filter, and the device is equipped with a rotating means for rotating the filter. Dust which cannot be discharge by its own weight since it is in a compressed state can be pushed out through the spiral rib formed on the outer periphery of the filter by rotating the filter, so that dust accumulated within the dust-collecting case in a compressed state can be easily discharged.
