Abstract

An electric vacuum cleaner according to the present invention includes a cleaner main body 16, and a suction unit 24 which is rotatably disposed at the bottom of the cleaner main body 16 and includes a suction port 23 and a rotary brush 25. The cleaner main body 16 includes a dust collecting chamber 19, and a fan chamber 18 equipped with an electric fan 17 disposed at the bottom thereof. A handle 21 having a grip portion 20 and a control circuit board 22 are installed above the dust collecting chamber 19. Components such as the handle 21 and the electric fan 17 are installed at the rear of the cleaner main body 16. 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.
