Laundry machine and washing method with steam for the same

摘要

Disclosed herein are a washing method and a laundry machine adopting the same, and more particularly, a steam washing method and a laundry machine that is capable of washing laundry only using steam and effectively performing a washing operation under the optimum operation condition. The steam washing method includes a selection step of allowing a user to select a steam washing course, in which a washing operation is performed only using steam, through an input unit, and an operation step of performing an operation based on the steam washing course while controlling at least one of a steam supply unit, a water supply unit, and a drum drive unit. The laundry machine includes an input unit for selecting a steam washing course, in which a washing operation is performed only using steam, among various washing courses, a steam supply unit for generating steam and supplying the generated steam to a tub or a drum, and a control unit for performing a control operation such that laundry received in the drum can be washed only using the steam when the steam washing course is inputted by the input unit.

主权项

1. A method of operating a laundry machine comprising:
sensing that a selected course at a first selector is a course using steam as an only water based substance entering a tub or a drum for cleaning the laundry from a plurality of courses which includes various washing courses for washing laundry using liquid water supplied into the tub or the drum; enabling a steam generator to generate and supply steam to the tub or the drum; and performing the selected course by using only the steam entering the tub or the drum for cleaning the laundry, wherein, at the performing the selected course, an operation condition of the selected course is decided according to an initial factor, where the initial factor includes at least an initial interior temperature of the tub or the drum, wherein the operation condition is decided depending upon a result of comparison between the initial interior temperature and a reference temperature range, and the operation condition includes at least one of an operation progress temperature of the interior the tub or the drum and an operation progress time, in order to decide and control an amount of steam to be supplied to the tub or the drum, wherein when the initial interior temperature is within the reference temperature range, the operation condition is decided based on the operation progress time, and when the initial interior temperature is out of the reference temperature range, the operation condition is decided based on the operation progress temperature.
