摘要：
A washing machine includes: a dewatering drum provided with an impeller in a free rotation manner; a driving part for rotating the impeller; an inertial rotation number detection part for detecting an inertial rotation number after the driving part stops driving; and a control part for controlling the driving part and the inertial rotation number detection part and detecting the amount of the washings in the dewatering drum as a load according to the inertial rotation number. In the case of determining that a detection result of the inertial rotation number detection part satisfies a specified condition, the control part enables the driving part to drive again; and the inertial rotation number detection part re-detects the inertial rotation number of the impeller, and detects the load according to the detection result and the previous detection result.
