Title:
ELECTRIC VACUUM CLEANER
Document Type and Number:
Japanese Patent JP2003079551
Kind Code:
A
Abstract:

To provide an electric vacuum cleaner suppressing discharge of a battery and providing usage for a long time.

A brush body 11 is provided in a neighborhood of a suction opening 10 in rear side of a traveling direction of a body case 2. Dust of a floor face is collected by the brush body 11. By a control circuit 14, a motor-fan 13 driven by electric power of a battery pack 20 sucks the dust collected by the brush body 11 from the suction opening 10 every predetermined time. Since cleaning can be carried out without constantly driving the motor-fan 13, consumption of the electric power of the battery pack 20 by the motor-fan 13 can be suppressed and the electric vacuum cleaner 1 can be used for a long time. It is also favorable to suck the dust collected by the brush body 11 from the suction opening 10 by the motor-fan 13 when the body case 2 moves a predetermined distance. Since cleaning can be carried out without constantly driving the motor-fan 13, consumption of the electric power of the battery pack 20 by the motor-fan 13 can be suppressed and the electric vacuum cleaner 1 can be used for a long time.
