Title:
VACUUM CLEANER
Document Type and Number:
Japanese Patent JP2012005559
Kind Code:
A
Abstract:

To provide a vacuum cleaner superior in dust collection performance as well as in usability.

The vacuum cleaner includes: an intake device 31 that sucks in floor surface dust and has a built-in electric motor 10 to drive a rotary brush 30 ; a moving speed detector 52 that detects the speed of the intake device 31 during its reciprocal movement ; a current sensor 41 that detects the condition of floor surface; an electric blower 2 that generates a sucking force; a dust collection detector 51 that detects intaken dust ; a signal controller 4 that receives outputs of the moving speed detector 52, current sensor 41, and dust collection detector 51 and controls the speeds of the electric motor 10 and electric blower 2 so that the best dust collection condition can be obtained thereunder. Thereby, the cleaner can grasp the floor surface state so as to copmpletely intake dust if any. To enhance the dust intake efficiency through the user's reciprocating action, the speeds of the electric motor 10 and electric blower 2 can be optimized to take in dust completely and achieve the best dust collection as required by the user.
