| 摘要 |
A DRUM-TYPE WASHING MACHINE INCLUDES A CASING (1), A WASHING TUB (2), A DRUM (3), A MOTOR (4), A VIBRATION DETECTOR (6), A FREQUENCY COMPONENT CALCULATOR (9), AND A CONTROLLER (7). THE DRUM (3) WITH AN AGITATING PROTRUSION (12) ON ITS INNER PERIPHERAL WALL IS PLACED IN THE WASHING TUB (2) FOR CONTAINING A LAUNDRY. THE VIBRATION DETECTOR (6) DETECTS VIBRATION ACCELERATION OF THE WASHING TUB (2). THE FREQUENCY COMPONENT CALCULATOR (9) CALCULATES A FREQUENCY COMPONENT IN THE VIBRATION ACCELERATION DETECTED BY THE VIBRATION DETECTOR (6). THE CONTROLLER (7) CONTROLS A FORWARD-REVERSE CONTINUOUS PIVOT DRIVE MODE, AND ALSO DETERMINES THE STATE OF LAUNDRY IN THE DRUM (3) DURING WASHING OR RINSING, BASED ON A RESULT RECEIVED FROM THE FREQUENCY COMPONENT CALCULATOR (9). |
