Problems solved by technology

[0004] However, in such a structure, since the dust and the like are sucked from the main body of the cleaning head through the flexible hose, there is a problem that the ventilation resistance is large, the suction efficiency is low, and dust clogging is easily formed in the flexible hose.

Abstract

PURPOSE: To provide a vacuum cleaner of an upright type which enables both of floor cleaning and cleaning at hand, has improved suction efficiency from a suction tool body in floor cleaning and in which dust clogging is suppressed. CONSTITUTION: This vacuum cleaner is provided with the suction tool body 1 and a cleaner body 2 supported so as to freely swing on the suction tool body 1, is provided with a main body side flow passage from the suction tool body 1 to a dust collecting chamber of the cleaner body 2 and a flow passage for cleaning at hand to the dust collecting chamber, and is provided with an at-hand cleaning flow passage opening / closing means for closing the flow passage for cleaning at hand in a state of inclining the cleaner body 2 and performing floor cleaning and opening the flow passage for cleaning at hand in a state of erecting the cleaner body 2.

Description

technical field [0001] The invention relates to an electric vacuum cleaner. Specifically, it relates to an upright electric vacuum cleaner which can improve the air suction efficiency of the main body of the dust collection head, suppress dust clogging, and can simultaneously perform floor dust collection and hand-held dust collection during floor dust collection. Background technique [0002] Generally, the structure of the vertical electric vacuum cleaner is to form a flow path connecting the main body of the suction head and the dust collection room in the main body of the vacuum cleaner. However, although such a structure can vacuum the dust on the ground, it cannot clean the chairs and steps. Wait for vacuuming. [0003] Therefore, people have developed a kind of upright electric vacuum cleaner that can not only vacuum the ground but also can vacuum the places other than the ground. In this conventional vertical electric vacuum cleaner, one end of the flexible hose is...
