Abstract

A drum-type washing machine provided with a dirt concentration detection unit for detecting the dirt concentration of wash water in a water tank, and a control unit, wherein the control unit executes a standard mode in which a standard washing step is performed, and a discoloration-minimizing mode different from the standard mode. In the washing step of the discoloration minimization mode, the control unit executes a first washing action in which a first agitation step is carried out during a first agitation step time period, which is shorter than a prescribed agitation step time period in the washing step of the standard mode, and the wash water is drained to a prescribed water level. The control unit executes, for a prescribed number of times, follow-up washing actions for supplying new wash water, newly performing an agitation step, and draining the water. The prescribed water level to which water is drained after the first agitation step is determined according to the dirt concentration level of the wash water in the first agitation step, as detected by the dirt concentration detection unit.

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 drum-type 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 the amount of detergent about twice the standard amount of detergent corresponding to the water level are displayed. , thereby improving cleaning performance with 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 ...
