Upright vacuum cleaner with sliding power indicator switch
First Claim
1. A vacuum cleaner, comprising:
- a main body housing a suction generating device and a filtering device;
a suction nozzle coupled to the suction generating device in the main body and configured to suck air containing foreign substances;
a handle coupled to the main body and configured to be gripped by a user while the vacuum cleaner is in use; and
a control switch installed on the handle and configured to control an on/off operation of the vacuum cleaner and to control a suction power of the suction generating device, wherein the control switch comprises;
a sliding electrical switch mounted on the handle and having a slide element that is capable of causing the suction generating device to turn on and off, and capable of controlling an amount of suction provided by the suction generating device;
an indicator mounted on the handle and having markings to indicate different suction power levels; and
a sliding knob mounted over the indicator and configured to be moved, by the user, to selectively overlie different portions of the indicator to provide an indication of the suction power level setting of the vacuum cleaner in combination with the indicator, wherein the sliding knob includes a connection portion that is coupled to the slide element of the sliding electrical switch such that the slide elements moves with the sliding knob.

Abstract
The present invention relates to an upright vacuum cleaner. An upright vacuum cleaner according to the present invention includes a main body for housing a suction power generating device for sucking air and a filtering device for filtering out foreign substances contained in the sucked air. A suction nozzle is 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 is installed at the top of the main body and is designed to be gripped by a user in use. The potentiometer, or some other device for controlling the electric current applied to the suction power generating device, is installed at one side surface of the handle. The potentiometer allows the user to control a suction power level and on/off operations of the vacuum cleaner by means of a sliding manipulation. Further, the potentiometer is preferably installed at a front surface of the handle.
