A laundry drier control method reads a temperature variation rate per unit time, to enable drying according to the amount and type of an object being dried. The method includes steps of initiating a drying procedure; measuring a temperature variation rate per unit time over the drying procedure; calculating an overall drying time based on the measured temperature variation rate per unit time; and performing the drying procedure for the calculated overall drying time. The drying time determining step is repeated if a substantial increase in the temperature variation rate is detected.

Laundry dryer control method

The present invention discloses a method for controlling a washing machine for shortening a washing time period and extending lifetimes of components of the washing machine. For this, the present invention provides a method for controlling a washing machine including the steps of sensing a laundry amount, repeatedly supplying washing water to a tub of the washing machine with reference to the laundry amount sensed thus, and circulating the washing water for a predetermined time period for wetting the laundry, wherein the step of circulating is performed only once.

Method for controlling washing machine

A laundry drier control method is provided, by which drying time is dynamically controlled according to an amount and type of a drying object, using a calculated medium temperature to determine a medium temperature time. The method includes steps of initiating a drying procedure by actuating drivers, including a heater driver to increase an internal temperature of a laundry drier; determining a medium temperature time by measuring a time lapse from the drying procedure initiating step to a point where the internal temperature reaches a medium temperature between a drying initiation temperature and a maximum drying temperature; setting a drying time based on the determined medium temperature time; and performing the drying procedure for the set drying time. The drying time is set by multiplying the determined medium temperature time by a predetermined factor. The drying initiation temperature is the internal temperature at the time of initiating the drying procedure. The maximum drying temperature is a predetermined temperature set according to a user command at the time of initiating the drying procedure.

Laundry drier control method

Disclosed is a washing machine capable of changing program and solving a fundamental problem of malfunction. The washing machine includes: a storage tank mounted vertically or horizontally for storing washing water; an inner tub mounted vertically or horizontally inside the storage tank in a rotatable manner; a load part including a motor for rotating the inner tub, water supply means for supplying water and drain means for draining water; a drive micom for controlling the load part; a key input part for allowing a user to input various operation orders or to set functions of the washing machine; a display part for displaying the functions and operation conditions; a memory capable of reading and writing and for storing operation algorism of the washing machine and information related with the washing machine; an interface part for inputting and outputting data with an external device; and a system micom for controlling the drive micom for performing a washing operation corresponding to the user's operation order through the key input part, controlling the display part for displaying the corresponding operation condition or function and storing data transferred from the external device through the interface part into the memory. The washing machine can maximize convenience, washing performance and operational efficiency.

Washing machine

A drying method for a drum-type washing machine includes the steps of: draining water from a load of laundry by maintaining a predetermined drying speed for a predetermined time in an initial drying step performed during a drying stroke of the drum-type washing machine; and sensing whether an eccentricity exists after expiration of a predetermined time and, if the eccentricity is not sensed, accelerating the drying speed to accomplish drying of the laundry. The drying method prevents a drum of the washing machine from generating a flushing noise in the case where an imbalance occurs during drying, and also prevents the laundry from becoming crumpled from sticking to the drum at the end of the drying procedure.
