Description

  The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner provided with a filter dust removal mechanism that responds to rotation of a dust collecting hose.

  In a conventional vacuum cleaner, a pleated filter is often used as a dust separating means for separating dust sucked from a surface to be cleaned through a dust collecting hose from air.

  A suction port to which a dust collecting hose is connected is provided on the front surface of the vacuum cleaner main body, and a first dust separating means that employs a method of separating using an inertial force is provided opposite to the suction port. A pleated filter is provided as a second dust separating means vertically installed on the downstream side of the first dust separating means, and the dust attached to the pleated filter is removed by a manual operation unit and the operation unit. There has been proposed a vacuum cleaner that removes dust by a dust removing mechanism including an operation unit (see, for example, Patent Document 1).

  However, the electric vacuum cleaner described in Patent Document 1 has a room for improvement because the dust removed from the pleated filter is not easily dropped by gravity, the structure of the dust removal mechanism is complicated, the dust removal frequency is low, and there is room for improvement.

  In addition, the pleat filter as the second dust separation means is arranged in an inclined state to promote the fall of the dust that has been removed, but the pleat filter is rotated by a dust removal mechanism equipped with a motor, An electric vacuum cleaner that removes dust by flipping a pleated filter with a dust removing member has been proposed (for example, see Patent Document 2).

However, the vacuum cleaner described in Patent Document 2 has a limit to the inclination angle of the pleat filter due to the space in which the pleat filter is disposed, and is insufficient for dropping the dust by gravity, Also, the structure of the dust removal mechanism is complicated and there is room for improvement.
