[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rechargeable cleaning system in which a storage battery is provided inside a cleaner body, and a cleaning operation is performed by driving an electric fan by power supply from the storage battery charged from the outside. About the machine.

[0002]

2. Description of the Related Art Vacuum cleaners widely used in general households are equipped with an electric fan for suction and a dust collection chamber for dust collection. A vacuum cleaner main body having wheels, an intake pipe connected to the intake port via a flexible intake hose, and a suction tool detachably attached to a tip of the intake pipe. Gripping a handle provided on a part of the suction pipe, pressing the suction tool at the tip against a desired cleaning surface while moving the cleaner body on the floor by rolling the wheels, and in this state, the electric fan Driven and used.

At this time, the rotation of the electric fan causes
From the suction tool, the flow of suction air introduced into the cleaner body through the suction pipe, the suction hose and the suction port is generated, and the dust around the suction tool is sucked along with the suction, and is provided in front of the electric fan. Collected in the dust collection chamber.

In the above-described vacuum cleaner, an electric fan inside the vacuum cleaner body is generally connected to a power source indoor or outdoor through a power cord provided so as to be able to be pulled out to the outside, and from this power source. However, in this configuration, the power cord restricts the range of movement of the cleaner body, so that it is necessary to change the connection of the power cord every time the cleaning place is changed. There is a problem, and there is a problem that the power cord pulled out with the movement of the cleaner main body obstructs the operation of the suction tool on the floor.

[0005] In order to solve such a problem, a rechargeable vacuum cleaner has been conventionally proposed. This vacuum cleaner
The storage battery is built into the main body of the vacuum cleaner having an electric fan and a dust collection chamber, and the electric fan is driven by power supply from the storage battery, so that it is not necessary to draw out a power cord for connection to an external power supply. is there.

[0006] The storage battery is always kept usable by charging it from outside when not in use. Japanese Utility Model Publication No. 6-8852 (A47L 9/28, 5/28) discloses a non-use battery. A charger is built into the mounting table on which the vacuum cleaner body is mounted during use, and is configured as a charging base.When the vacuum cleaner body is mounted on this charging base, the charging terminal on the charging base side and the vacuum cleaner main body side A charge-type vacuum cleaner has been disclosed in which a charge receiving terminal is in contact with each other, and the contact portion is released to charge the storage battery from the charger. Can be effectively prevented.
