Abstract

The drum type washing machine has a blackening suppression program in addition to a standard program for performing a standard washing process, and is equipped with a dirt concentration detection unit (18) and a control unit (20) for detecting the dirt concentration of washing water in a water tank (2). . The washing process includes a stirring process of washing the clothes by rotationally driving the rotary drum (3). In the cleaning process of the blackening suppression program, the control unit (20) executes the first cleaning operation. After performing the first stirring process for a predetermined time (T1), the washing water in the water tank (2) is drained. Thereafter, an additional washing operation is performed. In this additional washing operation, new washing water is supplied, and the washing water is drained after performing the stirring process for the second stirring process time (T2). The dirt concentration of the washing water in the first stirring step is detected by a dirt concentration detection unit (18), and the number of additional cleaning operations is determined based on the contamination level obtained by the detection.

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...
