Abstract
An electric vacuum cleaner according to the present invention includes a cleaner main body , and a suction unit which is rotatably disposed at the bottom of the cleaner main body and includes a suction port and a rotary brush . The cleaner main body includes a dust collecting chamber , and a fan chamber equipped with an electric fan disposed at the bottom thereof. A handle having a grip portion and a control circuit board are installed above the dust collecting chamber . Components such as the handle and the electric fan are installed at the rear of the cleaner main body . With this configuration, the vacuum cleaner is prevented from falling down when it is set upright. Further, the safety in use of the vacuum cleaner will be improved. Also, the user is able to easily use the vacuum cleaner. Furthermore, it is possible to finish assembling the component parts only at the rear of the vacuum cleaner. Accordingly, the number of parts to be assembled and disassembled can be decreased. Also, it is possible to shorten the time required for the assembling job and, further, to improve the workability.
