Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a vacuum cleaner having a cord reel.

[0002]

2. Description of the Related Art Conventionally, as a vacuum cleaner having a cord reel, as shown in Japanese Patent Application Laid-Open No. 9-206248 (A47L9 / 00) and the like, a dust collection chamber is provided at the front of the cleaner body, and an electric blower and a cord are provided at the rear. A configuration in which reels are juxtaposed is known.

[0003] In such a vacuum cleaner, the portion corresponding to the code reel of the partition separating the front and rear of the vacuum cleaner main body is closed, so that there is a disadvantage that the effective dust collection area is reduced and the dust collection efficiency is reduced. .

Further, since the electric blower and the code reel are juxtaposed in the left and right direction, the width of the cleaner main body is increased, and the heaviest electric blower is biased to one side of the cleaner main body. The balance was poor, it was difficult to hold the main body when carrying the cleaner, and the problem was that the main body of the vacuum cleaner tilted during cleaning.

Further, Japanese Patent Application Laid-Open No. 5-95860 (A47L 9/0
As shown in (0) and the like, there is also known a vacuum cleaner in which a dust collecting chamber is arranged in front of the main body, and an electric blower and a code reel are sequentially arranged (in a column) behind the dust collecting chamber.

In such a vacuum cleaner, since the electric blower and the cord reel are located substantially at the center in the left-right direction of the cleaner body, the weight balance of the cleaner body is improved, but the cleaner body is longer. There are disadvantages.

Further, in order to cool the cord, the exhaust of the electric blower is guided to a cord reel to cool the cord.
Since the exhaust of the electric blower is hot air, there is a problem that the cooling efficiency of the cord is poor, and the carbon powder and fine dust contained in the exhaust of the electric blower adhere to the cord and stain the cleaning surface when the cord is pulled out. .

[0008]
