Abstract

There is provided a method of controlling a vacuum cleaner having a dust collection unit in which dusts separated from air sucked by a suction motor are stored. The method includes operating the suction motor with a first driving force, determining an amount of the dusts stored in the dust collection unit, and operating the suction motor with a second driving force greater than the first driving force as the amount of the dusts increases.

Description

technical field [0001] The present invention relates to a control method of a vacuum cleaner, and more particularly, to a vacuum cleaner capable of allowing the vacuum cleaner to suck dust with a uniform suction force by changing the driving force of a suction motor according to the amount of dust stored in a dust collection unit. Control Method. Background technique [0002] Generally, a vacuum cleaner is a device capable of sucking dust-containing gas using vacuum pressure installed in a main body and filtering the dust in the main body. [0003] Vacuum cleaners are divided into tank type and column type. The canister type vacuum cleaner includes a main body and a suction nozzle connected to the main body through a connecting pipe. The upright type vacuum cleaner includes a main body and a suction port integrally formed with the main body. [0004] Meanwhile, the dust collection unit installed in the cyclone type vacuum cleaner separates the dust from the gas using the ...
