Abstract: A washing machine and a method of controlling the same are disclosed. The amount of laundry that is introduced into the washing machine is measured using gravity and inertia applied during the operation of the motor, whereby it is possible to precisely calculate the amount of laundry and to minimize the effects of the initial position of the laundry and the movement of the laundry. In addition, the current value of the motor that is operated is used to measure the amount of laundry without a sensor. Furthermore, the amount of laundry is measured at the rotational speed of the motor at which the laundry clings to the drum, whereby it is possible to minimize an error due to the movement of the laundry to thus improve accuracy. Moreover, it is possible to determine the amount of laundry within a short time. Consequently, it is easy to commence the spin-drying operation, thereby reducing washing time and saving energy.

Abstract: An amount of laundry that is introduced into a washing machine is determined by identifying gravitational and inertia forces applied during the operation of a motor, whereby it is possible to precisely calculate the amount of laundry and to minimize the effects of the initial position of the laundry and the movement of the laundry. In addition, the current value of the motor that is operated is used to measure the amount of laundry without a sensor. Furthermore, the amount of laundry is measured at the rotational speed of the motor at which the laundry clings to the drum, whereby it is possible to minimize error due to the movement of the laundry to thus improve accuracy.

Abstract: Disclosed are a dishwasher that sprays wash water to wash dishes or cookware and a method of controlling the same. The method of controlling the dishwasher includes supplying wash water from an external water source to a sump and intermittently driving a washing pump to change the level of water around a filter, thereby removing filth from the filter.

Abstract: An amount of laundry that is introduced into a washing machine is calculated using gravity and inertia applied during the operation of a motor, whereby the amount of laundry is precisely measured and effects of the initial position of the laundry and the movement of the laundry are minimized. In addition, a measured current of the operated motor is used to determine the amount of laundry without a sensor. Furthermore, the rotational speed of the motor is controlled stepwise from a low speed to eliminate variation due to vibration. Moreover, the characteristics of gravity in the low-speed maintenance period are used to effectively calculate the amount of laundry, and the characteristics of inertia in the acceleration period are also used, whereby it is possible to precisely determine the amount of laundry. Consequently, it is easy to commence the spin-drying operation, thereby reducing washing time and saving energy.
