CONTROLLING METHOD OF ELECTRIC CLEANER

摘要

The vacuum cleaner comprising a pressure sensor installed at the dust collector of vacuum cleaner for detecting internal pressure and an amplification circuit amplifying the input signal outputted by the pressure sensor, increases the absorption force by increasing the revolution per minute (RPM) of motor when the inner air pressure measured by pressure sensor is over the set value in advance. On the other hand, the revolution per minute of motor is decreased. This vacuum cleaner has the constant absorption force regardless of the clogged degree of absorption pipe.
