Description

  The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner that can be used with both a commercial power source and a storage battery.

  2. Description of the Related Art Conventionally, there has been proposed a vacuum cleaner that includes a vacuum cleaner main body incorporating a storage battery, and a power supply extension device that is provided separately from the vacuum cleaner main body and incorporates a cord reel (see, for example, Patent Document 1). ).

  That is, as shown in FIG. 15, the electric vacuum cleaner 200 of Patent Document 1 includes a cleaner main body 202 having an electric blower 201 that generates suction air, a suction tool 203 that sucks dust on a surface to be cleaned, and one end. Is connected to the suction device 203, one end is connected to the extension tube 204, the other end is connected to the cleaner body 202, and the cleaner body 202 is connected to supply commercial power. A power supply extension device 207 having a cord reel 206 and a power cord 208 for supplying commercial power to the power supply extension device 207 are configured. Further, the cleaner body 202 includes a storage battery 209 that supplies power to the electric blower 201.

  When the power cord 208 is connected to a commercial power source and the cord reel 206 is connected to the vacuum cleaner body 202, the conventional vacuum cleaner 200 uses the commercial power source as the power source of the electric blower 201. When the electric vacuum cleaner 200 is operated and the power cord 208 is not connected to the commercial power source or the cord reel 206 is not connected to the main body 202 of the vacuum cleaner, the storage battery 209 is used as the power source of the electric blower 201 And it is comprised so that the vacuum cleaner 200 may be operated.

  However, the conventional vacuum cleaner still has room for improvement from the viewpoint of improving the usability of the vacuum cleaner.

  That is, the conventional vacuum cleaner can obtain a higher suction work rate when using a commercial power source than when using a DC power source from a storage battery, but not only the main body of the vacuum cleaner but also the power supply extension device at the same time. There was a problem that it had to be moved and was unusable and poor in cleaning workability.

  Therefore, it is conceivable to incorporate both the storage battery and the cord reel in the cleaner body. However, a storage space for the storage battery and the cord reel is required, and there is a problem that the cleaner body is enlarged.

  The present invention has been made in view of the problems of the prior art, and incorporates a cord reel for supplying commercial power and a storage battery for supplying DC power into the main body of the cleaner while suppressing an increase in size of the main body of the cleaner. An object is to provide a vacuum cleaner.

In order to solve the above-described problems of the prior art, the present invention includes a vacuum cleaner body that includes an electric blower that generates suction air, and extends from the side surface of the vacuum cleaner body toward the left-right direction of the vacuum cleaner body. A pair of left and right axle parts, and a pair of left and right wheel parts rotatably attached to the outer periphery of the axle part. A storage battery for supplying DC power to the electric blower is disposed on one of the axle parts. On the other side, a cord reel connected to a commercial power source and supplying AC power to the electric blower is arranged.

  According to the vacuum cleaner of the present invention, both the commercial power source and the storage battery can be used as the drive source, and the usability can be improved. Moreover, since the cord reel and the storage battery are disposed using the space in the axle of the cleaner body, it is possible to suppress the size of the cleaner body from being increased.
