However, the arrangement of the intake port 25 and the exhaust port 26 is not limited to this, and the intake port 25 is disposed below the exhaust port 26 by providing the intake port 25 in the pedestal portion 21 and providing the exhaust port 26 in the column portion 22. It may be done. In such a configuration, for example, the blowing direction by the fan 28 may be reversed. According to such a configuration, dust that rises from the floor surface can be effectively sucked and purified from the intake port 25 arranged in the pedestal portion 21.

  Moreover, in the vacuum cleaner of this Embodiment 1, although the exhaust port 26 was provided in the side surface of the base part 21, arrangement | positioning of the base part 21 is not restricted to this, For example, as providing on the upper surface of the base part 21 Also good. Note that the rear surface of the pedestal 21 is not suitable for the arrangement of the exhaust ports 26. This is because the back side of the pedestal 21 is assumed to be in close contact with the wall, and in this case, the exhaust port is blocked. Moreover, even if it is not in close contact with the wall, if the exhaust continues to hit the wall, the wall may become dirty. For this reason, when the exhaust port 26 is disposed on the side surface or the upper surface of the pedestal portion 21, the angle of the louver 261 is set so that the exhaust direction is lateral or forward, that is, the exhaust direction is not the rear direction. Is preferably set.
