Description

  The present invention relates to a vacuum cleaner.

Conventionally, a dust collecting tank having a bottomed cylindrical body that opens upward and having a hose connection port on a side surface, and an electric blower that is detachably attached to the opening side of the dust collecting tank and generates a suction force are incorporated. 2. Description of the Related Art A vacuum cleaner including a main body unit is known (for example, see Patent Document 1).
In this vacuum cleaner, dust sucked together with air by a driven electric blower through a hose connection port is collected in a dust collection tank. Further, the exhaust air from the electric blower is exhausted from an exhaust port provided in a main body case constituting the main body unit.
In such a dust collecting tank type vacuum cleaner, a relatively large capacity of the dust collecting section can be ensured. Therefore, the dust collecting tank type vacuum cleaner is suitably used as a so-called commercial vacuum cleaner for cleaning a building having a large cleaning area at a time.
The length of the power cord of the commercial vacuum cleaner is longer than that of the home vacuum cleaner so that it can cope with a case where the cleaning area is large. Also, unlike home vacuum cleaners, many commercial vacuum cleaners do not have a cord reel for winding a power cord.
Therefore, in preparing work for using the business-use vacuum cleaner and removing the business-use vacuum cleaner after use, it is extremely complicated to handle long power cords. Therefore, it is desirable that the main body unit also includes a code reel capable of pulling out and pulling in the power cord to and from the main body of the vacuum cleaner.
