Abstract: A washing machine and an operating method of the washing machine are provided. In the operating method of the washing machine, it is determined whether a washing machine has a regular laundry load or a single laundry load based on the amount of laundry and the number of times of detection of the amount of laundry. Therefore, it is possible to precisely determine the laundry load of a washing machine, reduce the time taken to determine the laundry load of a washing machine, and prevent a washing machine from being damaged by a misreading of the laundry load of a washing machine.

Abstract: A laundry treatment apparatus is provided that includes a condensing pool disposed within a water supply port formed in a tub, a water supply passage formed between the condensing pool and the water supply port, and a cap that guides water to the condensing pool and stops steam flowing backward through the water supply passage so that the steam is introduced into the condensing pool. The steam flowing backward from an inside of the tub to the water supply port of the tub is brought into contact with the water contained in the condensing pool and is condensed, thereby preventing pollution of a detergent holder or peripheral portions thereof, which may occur when the steam flows backward into the detergent holder or peripheral portions thereof via the water supply port of the tub.

Abstract: A washing machine having height adjustable legs is provided. The washing machine may include a base provided at a bottom of the washing machine, a plurality of legs coupled to the base, and an over-unscrewed prevention member provided with each leg. Each leg may include a bolt that is height-adjustably assembled at the base. The over-unscrewed prevention member may be provided at the bolt of each leg and caught by the base when the legs are unscrewed so as to set a maximum unscrew height of the legs.

Abstract: A defrosting method of a drum-type washing machine is provided. The defrosting method includes performing a warm water supply operation upon receiving a defrost command; performing a water discharge operation; performing a heating operation if a water level has not yet decreased; and performing an additional water discharge operation.

Abstract: An automatic height adjustment leg of a laundry handling apparatus according to the present invention comprises a cylinder mounted to a base of a laundry handling apparatus; a piston movably arranged inside the cylinder; a elastic member installed in the cylinder so as to elastically support the piston; and a leg penetrating the cylinder and fixed to the piston. There are provided advantages that the horizontality of the laundry handling apparatus may be automatically adjusted as the piston and leg move on and vibration may be absorbed and reduced by the elastic member.

Abstract: A detergent box for a washing machine is provided. The detergent box is slidably coupled to a front portion of the washing machine, and has a structure that prevents release of the detergent box from the washing machine even if the washing machine is tilted or shaken, and that facilitates proper placement of the detergent box. The detergent box may include a stopper, and a rib having an elastic slot formed therein. The detergent box holds washing agents, and the dispenser is mounted in the washing machine so as to receive the detergent box therein. The dispenser has a recess for seating the stopper therein as the detergent box is placed in the dispenser. The rib may include an elastic slot to provide an elastic force to the stopper.

Abstract: A washing machine and a method of controlling the same that is capable of determining whether laundry is a single load or a multiple load based on detected value of eccentricity or detected laundry amount and changing revolutions per minute of a motor or the number of eccentricity detections based on the determined load amount such that different spin-drying actions are performed. The washing machine comprises an eccentricity detecting unit for detecting eccentricity of laundry received in a drum, a motor driving unit for driving a motor such that the drum is rotated, and a microprocessor for determining whether the laundry is a single load or a multiple load based on the value of eccentricity detected by the eccentricity detecting unit and changing revolutions per minute of the motor or the number of eccentricity detections of the eccentricity detecting unit based on the initially determined load amount.
