Problems solved by technology

Therefore, it takes a long time to detect turbidity, and there are still problems in the detection accuracy of turbidity.
[0010] In addition, with the previous technology, it is difficult to control the washing process and rinsing process after detecting the type of detergent and setting correspondingly according to the type of detergent. Then the method of turbidity detection is realized

Abstract

The washing machine comprises a drain pipe (75) communicated with the bottom of an outer tub (43), a feculent degree detection part (92) arranged inside the drain pipe for detecting the feculent degree of water according to the light transmittance degree, a cleaning hose (72) for connecting a water inlet valve (70) with the drain pipe and a control part (87). The feculent degrees of the tap waterentered via an inlet valve into the drain pipe and the cleaning liquid containing a cleaning agent in the drain pipe via the outer tub are compared by the control part so as to determine the type of the cleaning agent. Meanwhile, the time and the number during the washing and rinsing process are controlled by the control part, so that the cleaning agent is determined and the turbidity is detectedat an early stage with high precision.

Description

technical field [0001] The invention relates to a washing machine capable of controlling the actions of washing and rinsing operations according to the dirtiness of the washing liquid. Background technique [0002] In the prior art washing machine, it is a known technology to determine whether the washing is completed by detecting the turbidity of the washing liquid. For an example, refer to Japanese Patent Laying-Open Publication No. 57-66793 (hereinafter referred to as reference 1). [0003] In addition, Japanese Patent Laid-Open Publication No. Sho 61-159998 (hereinafter referred to as reference 2) also discloses a method to detect the turbidity detector when the washing machine is suspended and then restarted after the turbidity is detected. Sensitivity readjustment technique. [0004] Furthermore, there is another method in the prior art that can prevent misjudgment of whether the change in the turbidity of the washing water is caused by the dirt detached from the clot...
