摘要： A method for operating a washing machine (10) during a washing cycle, the washing machine having a washing tub (24) containing a laundry drum (26). The method has the steps of: detecting a liquid level (44) in the washing tub (24) and/or in a draining region thereof when the laundry drum (26) is rotating, comparing the detected liquid level (44) with an upper threshold value (48), when the detected liquid level (44) exceeds the upper threshold value (48), reducing the rotational speed of the laundry drum (26) and starting a predetermined monitoring period (54), detecting the liquid level (44) in the washing tub (24) and/or in the draining region thereof during the predetermined monitoring period (54), comparing the detected liquid level (44) with a lower threshold value (46) during the predetermined monitoring period (54), and if the detected liquid level (44) does not decrease or drop below the lower threshold value (46) within the predetermined monitoring period (54), then then starting a foam-reducing procedure.

摘要： A method for operating a washing machine (10) having a washing tub (24) containing a laundry drum (26). The method has the steps of: detecting a liquid level (44) in the washing tub (24) and/or in a draining region thereof while the laundry drum (26) is rotating at a first speed, comparing the detected liquid level (44) with an upper threshold value (48), wherein the excess of said upper threshold value (48) by the liquid level (44) while the laundry drum (26) rotates at a rotation speed equal or higher than the first speed generates a closed liquid ring at circumferential walls of the laundry drum (26), and if the detected liquid level (44) exceeds the upper threshold value (48), then reducing the rotational speed of the laundry drum (26) below the first speed and performing a foam-detecting procedure for detecting the amount and/or presence of foam inside the washing tub (24) and/or in the draining region thereof.

摘要： 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.

摘要： An embodiment of a method of determining inertia of a laundry load may comprise an extraction stabilization phase, where liquid is extracted from the laundry load by rotating the basket at first rotational speed, and a sensing phase. The sensing phase may include a deceleration phase, where the basket speed decreases to a second rotational speed, followed by an acceleration phase, where the basket speed increases back toward the first rotational speed. The inertia of the laundry load may be determined from data sensed during the deceleration and acceleration phases.

摘要： Disclosed is a drum type washing machine. A driving unit includes a driving motor and a clutch mechanism part, where the clutch mechanism part switches a driving form of the driving unit between a first-shaft driving form and a second-shaft driving form, the first-shaft driving form is a form that enables a wing shaft for transmitting rotation to a stirring body and a drum shaft for transmitting rotation to a drum to integrally rotate at a same rotation speed, and the second-shaft driving form is a form that enables the wing shaft and the drum shaft to respectively rotate at different rotation speeds. A control part executes first-shaft switching treatment which is treatment that enables the clutch mechanism part to work to move the clutch body to the first position and then enables the driving motor to rotate to engage the unengaged engaging flange part with the engaged recess.
