Title: DEVICE AND METHOD FOR DETECTING OPERATING BALANCE OF WASHING MACHINE
Abstract:
Disclosed are a device for detecting the operating balance of a washing machine and a detection method using the device. The device is symmetrically equipped with multiple pairs of magnets (11, 21, 31, 41) on the upper part of an outer drum (5) along the circumference, multiple pairs of reed switches (1, 2, 3, 4) are correspondingly disposed on the upper part of a box body (8) or at the lower part of a control disc seat, the reed switches (1, 2, 3, 4) are mounted on the inner wall of the box body (8) or on the part of the inner wall of the control disc seat that is the closest to the outer drum (5), and the reed switches (1, 2, 3, 4) and the magnets (11, 21, 31, 41) constitute a reed sensor for detecting the operating balance of the washing machine. A magnet (9) is mounted on an inner drum (7), and a reed switch is correspondingly disposed on the box body (8) or the control disc seat. The reed switch and the magnet (9) constitute a reed sensor for detecting the rotational speed of the inner drum (7). The operating balance and the rotational speed of the washing machine are detected by the detection method using this device. The device and method for detecting the operating balance of the washing machine have a simple structure, high sensitivity and a lower power consumption.
