Abstract

Provided is a drum-type washing machine, having a discoloration alleviation mode aside from a standard mode of carrying out a standard washing step, said drum-type washing machine comprising an impurity concentration sensing unit (18) which senses an impurity concentration in wash water within a water tank (2), and a control unit (20). The washing step includes an agitation step of rotation driving a rotating drum (3) and washing clothing. In the washing step of the discoloration alleviation mode, the control unit (20) executes a first wash action which carries out a first agitation step for a first prescribed time period (T1) which is shorter than a prescribed agitation step time period in the washing step of the standard mode and drains the wash water within the water tank (2). Thereafter, new wash water is supplied and a follow-up wash action executed which carries out the agitation step for a second agitation step time period (T2) and drains the wash water. The impurity concentration of the wash water in the first agitation step is sensed by the impurity concentration sensing unit (18), and the number of follow-up wash action cycles is determined according to the sensed impurity level.

Description

technical field [0001] The present invention relates to a drum type washing machine for washing clothes and the like. Background technique [0002] Conventionally, it has been considered to provide such a front-loading type washing machine with a blackening prevention program that improves cleaning performance and prevents clothing from being darkened (for example, refer to Patent Documents 1 and 2). [0003] In the conventional front-loading washing machine described in Patent Document 1, when the blackening prevention program is selected, the water level corresponding to the amount of cloth detected by the cloth amount detection unit and about twice the standard amount of detergent corresponding to the water level are displayed. Detergent dosage. Thus, cleaning performance is improved with a high detergent concentration to prevent darkening of clothes. [0004] With regard to the conventional drum type washing machine described in Patent Document 2, when the blackening p...
