First Claim
Patent Images
1. A vacuum cleaner comprising:
- dust amount detecting means or detecting the amount of dust in response to a signal outputted thereto from a sensor provided in an airflow passage and for producing an output;
comparing/counting means for performing a comparison and counting of the amount of dust and for producing an output;
a fuzzy inferring device for determining the speed of a motor in response to the output of said dust amount detecting means and the output of said comparing/counting means and for producing an output; and
means for holding the motor speed determined by said fuzzy inferring device for a predetermined period of time and or producing an output;
wherein after the motor speed is held for said predetermined period of time, said motor is driven for a certain period of time at the speed subsequently determined by sad fuzzy inferring device.

Abstract
A vacuum cleaner comprising a fuzzy inferring device for determining a motor speed in response to the amount of dust, and means for holding the motor speed determined by the fuzzy inferring device for a predetermined period of time, whereby, after the motor speed is held for the predetermined period time, the motor is driven for a certain period of time at the speed subsequently determined by the fuzzy inferring device.

3. A vacuum cleaner comprising:
-
dust amount detecting means for detecting the amount of dust in response to a signal outputted thereto from a sensor provided in an airflow passage and for producing an output; comparing/counting means for performing a comparison and counting of the amount of dust and for producing an output; a fuzzy inferring device for determining the speed of a motor in response to the output of said dust amount detecting means and the output of said comparing/counting means and for producing an output; means for holding the motor speed determined by said fuzzy inferring device for a predetermined period of time and for producing an output; and speed comparing means, in response to the output of said fuzzy inferring device and the output of said means for holding the motor speed, for immediately changing the motor speed to the output of said fuzzy inferring device if said output of said fuzzy inferring device exceeds the output of said means for holding during the predetermined period of time, wherein after the motor speed is held for said predetermined period of time, said motor is driven for a certain period of time at the motor speed subsequently determined by said fuzzy inferring device. - View Dependent Claims (4, 5)
