Abstract: A washing machine includes: a drum that rotates with a washing or drying object contained in the drum; a motor that rotationally drives the drum; a controller that controls rotation of the motor; and an electric current measurer that measures an electric current value representing an electric current flowing in the motor. The controller controls the rotation of the motor to rotate the drum less than one turn, and in accordance with the measured electric current value, detects whether a foreign object that is different from the object and whose mass is greater than an expected mass of the object is inside the drum. In a case where the controller detects the foreign object, the controller stops operation of the washing machine.

Abstract: A vibration-damping component of a washing machine comprises a suspender, a spring, a sleeve and an electromagnetic sensing device. The electromagnetic sensing device comprises an electromagnetic coil and a magnet. The electromagnetic coil surrounds the sleeve, the magnet and the spring are arranged in the sleeve and are fixed on the suspender, the sleeve surrounds the suspender in a slidable manner, and the weight of clothing is determined through measuring magnetic flux change of the electromagnetic coil when the sleeve slides on the suspender. In addition, the magnet and the electromagnetic coil make relative displacement, inductance in the electromagnetic coil changes, and water inflow can be detected through detecting the inductance. When dewatering begins, the vibratory magnitude of an outer drum is determined through the inductance change of the electromagnetic coil, and the stability of dewatering operation of the washing machine can be controlled accordingly.

Abstract: A drum washing machine, and a control method and a control apparatus for same are provided. The control method for the drum washing machine comprises the following steps: acquiring an average starting power of a drum in a starting process of the drum; acquiring a load range to which a current load of the drum belongs according to the average starting power; and setting a weighing protection velocity fluctuation threshold according to the load range to which the current load of the drum belongs. A value of the current load is obtained by using a correspondence between load with different weights and average starting powers. A weighing protection velocity fluctuation threshold is set according to the value of the current load to avoid the collision with the drum and non-dehydration in case of only one piece of clothing.

Abstract: Disclosed is a washing machine failure detection and processing method, comprising the following steps: a PC pointer detection step: respectively detecting various running processes of a washing machine; respectively detecting whether a current value of a logical register is the same as an assigned value after the running of various subprograms is ended, and if the current value is different from the assigned value, judging that a PC pointer fails, and keeping a record of a current failure occurring in which running process of the washing machine according to the assigned value; and when it is judged that the PC pointer fails, waiting for a time t1, and continuing to detect whether the current value of the logical register is the same as the assigned value, and if so, continuing to execute the subprogram, otherwise executing system resetting. In the washing machine failure detection and processing method in the present invention, an internal running error is prevented from occurring in an algorithm of a washing machine, a failure is detected by a system before being found by a user, and a corresponding security control measure is adopted, thereby guaranteeing the secure running of the washing machine.
