However, in the configuration of the conventional vacuum cleaner described in Patent Document 1, the extension pipe 33 or the engaging portion 33a provided on the suction tool 32 is engaged with the engaged portion 31a provided on the vacuum cleaner main body 31 from above. At the time of fitting, if the positions of the engaging portion 33a provided on the extension pipe 33 or the suction tool 32 and the engaged portion 31a of the vacuum cleaner main body 31 are not accurately aligned, the engaging portion 33a and the engaged portion 31a will be engaged. There was a problem that the engagement was disengaged.

The present invention solves the above-mentioned conventional problems, and allows the engaging portion provided on the extension pipe or the suction tool to be easily fitted with the engaged portion provided on the vacuum cleaner body so that the storage work can be easily performed. The purpose is to provide a vacuum cleaner.

In order to solve the above-mentioned conventional problems, the electric vacuum cleaner of the present invention is an electric vacuum cleaner capable of engaging an extension pipe with the electric vacuum cleaner main body upright, and a front surface of the electric vacuum cleaner main body is formed. An intake frame body having an intake port is arranged, and an engaged portion having a concave shape for engaging the extension pipe with the intake frame body and an engaged portion arranged on the left and right sides of the engaged portion are provided. The extension pipe has an inclined wall inclined to the joint portion and an engaging portion for engaging with the engaged portion, and the engaging portion is provided with an inclined surface and a hooking portion , and the engaging portion is provided. After the inclined surface of the portion is brought into contact with the inclined wall, the extension pipe moves along the inclined wall by its own weight to fit the hooked portion to the engaged portion. A substantially L-shaped engaging portion of an extension pipe or a suction tool is provided at the entrance of the engaged portion without the user accurately aiming at the engaged portion provided below the intake port. By simply releasing the engaging portion along the inclined wall, the engaging portion can move along the inclined wall and be fitted with the concave engaged portion below the intake port. ..

The vacuum cleaner of the present invention can provide an easy-to-use vacuum cleaner capable of downsizing the vacuum cleaner body and easily storing the vacuum cleaner body.
