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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
