Electric vacuum cleaner

Abstract

An electric vacuum cleaner comprising a floor nozzle connected to a lower part of a main body of the electric vacuum cleaner and having a suction opening opened on a lower surface of the floor nozzle, a rotary brush disposed in the suction opening, a driving source, a power transmission system which transmits power from the driving source to the rotary brush, and a changeover unit which connects or disconnects power transmission of the power transmission system, wherein the changeover unit is provided with an operation pedal, which is manipulated to connect or disconnect the power, on a rear portion of the floor nozzle. It is possible for an operator to instantaneously turn on and off the driving of the rotary brush only by stepping down or lifting up the pedal while gripping the handle at rear side of the main body of the cleaner without stopping the movement of the cleaner.

Description

Technical field [0001] The present invention relates to an electric vacuum cleaner, in particular to an electric vacuum cleaner that can easily open and close a rotary brush without interrupting the movement of the electric vacuum cleaner. Background technique [0002] In a so-called vertical electric vacuum cleaner, a floor nozzle that moves along the ground surface is rotatably connected to the lower part of the main body of the electric vacuum cleaner about a horizontal axis, and a blower and a dust collector are installed in the main body. A suction port is opened on the lower surface of the ground suction nozzle. [0003] A rod-shaped handle is inserted into the upper part of the main body of the electric vacuum cleaner. Push and pull the handle to manually move the vacuum cleaner, and detect the operation of the handle to control the moving unit installed in the floor suction nozzle to move the vacuum cleaner. [0004] A rotating brush is provided in the suction port. The r...

Problems solved by technology

[0011] However, in a general electric vacuum cleaner, since the manipulation tool is provided on the front upper part of the floor suction nozzle as described above, the user who grasps the handle must bend down so that his hand reaches close to the main body of the electric vacuum cleaner. floor position

[0012] Therefore, it is difficult to maneuver the handling tool while moving the electric vacuum cleaner, and it is necessary to stop the movement of the vacuum cleaner to turn the rotary brush on and off when the cleaner reaches the junction of the carpet and the wooden floor

This operation is cumbersome and it is not possible to switch the drive of the rotating brushes on and off easily
