[0002]
[Prior art]
Conventionally, the electric vacuum cleaner has an electric blower housed in the main body of the vacuum cleaner, a suction port body is connected to the main body of the vacuum cleaner via a hose and an extension pipe, and the electric motor is disposed in the suction port body. The electric motor drives a rotary cleaning body that is a rotary body. The electric blower is connected to a commercial AC power source via a cord and is driven using the commercial AC power source as a power source. The electric motor is electrically connected to the main body of the vacuum cleaner via a hose and an extension pipe. Both of them are powered by commercial AC power.
[0003]
And only the electric motor is not operated in a state where the suction port body is not connected to the vacuum cleaner body, and in the state where the suction port body is not connected to the vacuum cleaner body via the hose and the extension pipe, Since the power is not supplied, the electric motor is not driven in a state where the suction port is not connected.
[0004]
[Problems to be solved by the invention]
However, in recent years, the power source of the motor of the suction port body and the power source of the electric blower of the vacuum cleaner body have been reduced due to reasons such as eliminating the electrical connection via the hose and extension pipe between the suction port body and the vacuum cleaner body. It is considered that a secondary battery is provided in the suction port separately from the commercial AC power source, and this secondary battery is used as a power source for the motor.
[0005]
On the other hand, when the suction port is connected to the main body of the vacuum cleaner and is not in a cleanable state, it is very difficult to operate the electric motor.
[0006]
With regard to this point, in the conventional system in which the power supply of the motor of the suction port body is supplied from the main body of the vacuum cleaner, if the suction port body is connected to the vacuum cleaner and is not in a cleanable state, the vacuum cleaner Since electric power is not supplied from the main body to the electric motor, the electric motor of the suction port is not operated.
[0007]
However, when a secondary battery is disposed in the suction port body and the electric motor is driven by the secondary battery, the suction port is not connected to the main body of the vacuum cleaner and is not cleanable. There is a problem that only the body electric motor may operate.
[0008]
The present invention has been made in view of the above problems, and even when the power source of the motor of the suction port body is separated from the power source of the electric blower of the main body of the vacuum cleaner, the suction port body is not in a cleanable state. It aims at providing the vacuum cleaner which does not operate an electric motor.
