Abstract

The present invention relates to an upright vacuum cleaner. The upright vacuum cleaner according to the present invention comprises a main body for housing a suction power generating means for sucking air and a filtering means for filtering out foreign substances contained in the sucked air; a suction nozzle pivotably connected to a lower portion of the main body for sucking the air containing the foreign substances and then guiding the sucked air into the main body; a handle installed at the top of the main body and gripped by a user in use; and a potential meter installed at one side surface of the handle and capable of controlling a suction power level and on/off operations of the vacuum cleaner by means of a sliding manipulation. Further, the potential meter is preferably installed at a front surface of the handle.

Claims

1. An upright vacuum cleaner, comprising:

a main body for housing a suction power generating means for sucking air and a filtering means for filtering out foreign substances contained in the sucked air;

a suction nozzle pivotably connected to a lower portion of the main body for sucking the air containing the foreign substances and then guiding the sucked air into the main body;

a handle installed at the top of the main body and gripped by a user in use; and

a potential meter installed at one side surface of the handle and capable of controlling a suction power level and on/off operations of the vacuum cleaner by means of a sliding manipulation.

2. The upright vacuum cleaner as claimed in claim 1, wherein the potential meter is installed at a front surface of the handle.

3. The upright vacuum cleaner as claimed in claim 1 or 2, wherein the potential meter comprises a slide volume switch assembly which contains a plurality of contacts having different resistance therein and from which a slide element protrudes;

a board which is installed at a front surface of the switch assembly and on which indications for suction power levels are printed; and

a slide knob (56) installed at a front surface of the board, operated by the user, and interlocked with the slide element, and wherein the potential meter is installed in an opening (42) formed in the handle so that the board and slide knob are exposed to the outside at the front surface.
