Embodiment Construction
[0027] Hereinafter, modes for implementing the present invention (hereinafter referred to as “embodiments”) will be described in detail with reference to the drawings as appropriate.
[0028] Such as figure 1 As shown, if the drum type washing machine S of this embodiment is at least equipped with an outer tank 2, a drum 3, and a motor M that drives the drum 3 to rotate (refer to image 3 ) drum type washing machine can be applied, an example of which will be described below. In addition, if figure 1 As shown, in the front-loading washing machine S, the direction in which the door 25 exists is defined as the front side, and the directions of front, rear, up, down, left, and right will be described.
[0029] Such as figure 1 As shown, the front-loading washing machine S has a casing 1 in which an outer contour is formed by combining steel plates and resin moldings, and has a drying function. The front-loading washing machine S is a device in which the rotating shaft of the ...

The present invention provides a washing machine capable of efficiently dissolving dirt in a washing liquid and detecting the amount of dirt with high precision. The casing (1), the outer tank (2) forstoring water therein, the drum (3) rotatably supported in the outer tank, the driving device (M) for driving the drum to rotate, and the water supply for supplying water to the outer tank a member (21), a detergent supply member (20) for supplying a detergent into the outer tank, a washing liquid state determining member (140) for detecting a state of the liquid in the outer tank, and a controldriving device, a water supply member (16), The operation control member (100) of the detergent supply member and the washing liquid state determination member performs the agitation step, the contamination amount detection step, and the second agitation step, and the agitation step is performed before the contamination detection step, and the second step is performed. The stirring step is performed after the soiling detecting step, and the rotation speed of the drum in the stirring step is higher than the rotation speed of the drum in the second stirring step.
Description
technical field [0001] The present invention relates to a washing machine for washing clothes and the like. Background technique [0002] The amount of dirt attached to clothing varies depending on the living environment. Therefore, in a washing course in which the same washing operation is performed, washing residue may be generated particularly on heavily soiled laundry. In Japanese Unexamined Patent Application Publication No. 2011-67312 (Patent Document 1), the cleaning time is determined by estimating the amount of contamination in the washing liquid. [0003] prior art literature [0004] Patent Document 1: Japanese Patent Laid-Open No. 2011-67312 [0005] However, a drum-type washing machine generally includes an outer tank for storing washing liquid, a drum rotatably supported in the outer tank, and a drive device for rotating the drum. The clothes stored in the lower part of the drum are lifted by the rotation of the drum, and the clothes are dropped from the up...
