US 2024/0271348 A1 · CLOTHES DRYER AND CONTROL METHOD THEREFOR

Abstract

A clothes dryer may include a drum in which laundry is receivable; a humidity detector to detect a dryness level of the laundry in the drum; and a controller configured to: obtain the dryness level of the laundry in the drum detected by the humidity detector while a first initial drying cycle is performed, determine a weight category of the laundry in the drum from a plurality of weight categories of laundry based on the obtained dryness level, obtain control information based on the determined weight category, and control, according to the obtained control information, a main drying cycle to dry the laundry in the drum after the first initial drying cycle is performed.

A method for controlling a drying operation of a clothes dryer including a drum in which laundry is receivable, a heater to heat air supplied to the drum, a temperature sensor to measure a temperature of air in the drum, a driving motor to drive rotation of the drum, and a pair of touch electrode sensors disposed in the drum to output a pulse signal indicating a moisture content of the laundry in the drum when contacted by the laundry in the drum,

the method comprising:
receiving a dry start command;
performing a first initial drying cycle, in response to receiving the dry start command;
counting a first number of times that the pulse signal is greater than or equal to a predetermined reference during each first time unit of a plurality of first time units that the first initial drying cycle is performed;
determining a first average of the counted first number of times for the plurality of first time units;
comparing the first average with a first threshold;
and
determining a weight category of the laundry in the drum from a plurality of weight categories of laundry according to a result of the compared first average.
