Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention includes a guide cover for winding a cord at a cord outlet of a cleaner body having a cord reel around which a cord of an electric blower is wound.
The present invention relates to an electric vacuum cleaner capable of temporarily fixing a plug in a guide cover during assembly of an electric vacuum cleaner in order to prevent the plug at the tip of the cord from being pulled inward of the main body of the vacuum cleaner.

[0002]

2. Description of the Related Art When assembling a conventional vacuum cleaner,
The cord reel around which the cord of the electric blower is wound is stored in one of the cases of the vacuum cleaner body, for example, in the lower case,
After disposing a tubular guide cover for guiding the winding of the cord between the cord outlet of the case and the reel, the upper case is joined to the lower case to integrally assemble the cleaner body. The cord is locked in the guide cover by a large diameter plug. When the vacuum cleaner body is assembled, the cord winding mechanism prevents the cord from being pulled out after the vacuum cleaner body is assembled together with the cord, so the guide cannot be pulled out after the vacuum cleaner body is assembled. There has been proposed a temporary fixing means for temporarily fixing the plug inserted in the cover in the guide cover.

In Japanese Patent Publication No. 61-44012, after a cord is sandwiched and temporarily fixed to an engaging portion formed on a cleaner body, a reel is installed on the cleaner body and finally the engaging portion while pulling a plug. Remove the temporary fixing of the cord by and finish the installation work of the reel. As another temporary fixing means, an opening on the reel side of the guide cover is formed in such a shape that only the cord can be inserted and the plug cannot be inserted, and a notch for inserting the cord is formed on the side surface of the guide cover. A stop member is used. At the time of assembly, the cord is pulled out from the reel, the cord is inserted into the guide cover through the notch, and the reel and the guide cover are housed in the case of the cleaner body. The plug is locked in the opening of the guide cover on the reel side.

[0004]

In the former plug temporary fixing means, before the reel is installed in the cleaner body, after the cord is temporarily fixed to the engaging portion and the reel is installed in the cleaner body,
Since the temporary fixing of the cord by the locking portion must be removed while pulling the plug, the reel installation work becomes complicated. Since the latter plug temporary fixing means has a notch in the guide cover, deformation is likely to occur during molding of the guide cover, and the notch is closed by another member after the cord is inserted into the guide cover. It is necessary to prevent the slipping out and the deformation of the guide cover.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electric vacuum cleaner having a plug temporary fixing means having a simple structure, which makes it easy to install the reel on the cleaner main body during assembly.
