Abstract: A washing method in a steam injection type washing machine in which wash water is heated to generate high temperature and high-pressure steam while passing through the steam supply unit in the wash or rinse cycle, and the generated steam is injected into the wash tub at the top of the wash tub. Accordingly, it is possible to rapidly achieve the wetting of clothes with wash water while achieving an enhancement in sterilization and washing performances. In addition, consumption of water and electrical energy can be reduced.

Abstract: Disclosed herein is a drum washing machine which is capable of lifting clothes to a predetermined height and then dropping the lifted clothes so that the clothes can be washed by means of friction and impact. The drum washing machine is capable of heating wash water and spraying the heated wash water into a tub and a drum of the washing machine in a phase of high-temperature and high-pressure steam, thereby rapidly soaking clothes in the wash water, improving sterilizing and washing efficiencies of the drum washing machine, and saving wash water and electric energy.

Abstract: A spray type drum washing machine including a tub mounted in a cabinet, and adapted to contain wash water therein, a circulation line connected between a portion of the tub and another portion of the tub to circulate wash water through the tub, a pump installed at the circulation line, and adapted to forcibly feed wash water through the circulation line for the circulation of the wash water through the tub, and an atomizing device provided at the circulation line, and adapted to atomize the wash water fed through the circulation line, whereby the wash water to circulate through the tub is supplied in an atomized state into the tub. The wash water can rapidly permeate clothes contained in the drum, so that it can more effectively come into contact with contaminants attached to the clothes. As a result, it is possible to achieve an enhancement in washing and rinsing performances while reducing the consumption of wash water.

Abstract: Disclosed herein is a suspension apparatus and a resonance avoiding method of a drum-type washing machine. The method adjusts elastic moduli of elastic members before a drum reaches a resonance speed during a dehydration cycle of the washing machine. If the rotating speed of the drum exceeds the resonance speed, the method returns the elastic moduli of the elastic members to an initial state, thereby preventing generation of resonance.

Owing to the above configuration, the dishwasher may be used cleanly and sanitarily, resulting in enhancing washing efficiency and endurance of a product.

Abstract: A dishwasher and assembly method thereof are disclosed, by which an overall height of the dishwasher is reduced, by which water can stably flow and by which assembly efficiency can be enhanced. The present invention includes a sump accommodating water therein and a wash pump assembled to the sump in a lateral direction to circulate the water within the sump.

Abstract: A washing machine and a washing method thereof are disclosed, in which waste of washing water is reduced and washing efficiency is improved. The washing method includes the steps of determining the volume of laundry in a tub, setting a first water level for a preliminary washing stroke and a second water level for a main washing stroke based on the determined volume of laundry, carrying out the preliminary washing stroke using washing water of the first water level and steam, and converting the preliminary washing stroke into the main washing stroke based on washing water of the second water level depending on an inner temperature of the tub.

Abstract: A drive unit for dish washing machines includes solid waste chambers with bottom surfaces that are stepped. One of the solid waste chambers has an inlet/outlet port. The solid waste chambers are inclined downward toward the inlet/outlet port. Consequently, filtering capacity is increased, and discharge of solid waste is facilitated.

Abstract: A drive unit for dish washing machines includes a flow channel housing, a filter housing and an arm holder, which are thermally fused to one another to form an integral unit. Consequently, assembly of the drive unit is simplified, leakage of wash water is prevented, and pumping performance is increased. Also, the flow channel housing, the filter housing and the arm holder are concurrently fixed to a pump housing of the drive unit by fixing members. Consequently, the assembly process of the drive unit is simplified, and the coupling force between the components of the drive unit is increased.
