  • Electric blower
    Publication number: 20060099084
    Abstract: The present invention provides an electric blower that performs: measuring an amount of airflow against a fan rotation speed of the blower with a load magnitude detected previously; determining an empirical formula to calculate a fan rotation speed to discharge an amount of target airflow in response to the magnitude of a load of the blower according to the data obtained from the above measurement repeated a plurality of times varying the magnitude of the load on the blower; operating, firstly in practice, the blower to detect the magnitude of the load of the blower, then to calculate the fan rotation speed to discharge the amount of target airflow using the empirical formula; and then changing the blower operation to the fan rotation speed given by the calculation.
