とはできなかつた。 Conventionally, washing machines have been operated using a time switch for a set period of time, and the user can set the time on the time switch based on past experience, depending on the amount of laundry, how dirty it is, etc. I'm going. Regarding the rinsing process, a method was considered in which an interrupter consisting of a light-emitting element and a light-receiving element was installed to detect the permeability of the rinsing liquid, and to automatically stop the operation when the permeability changed. As the washing process progresses, the permeability changes in the direction of increasing, so this cannot be used as is in the washing process where the permeability changes in the direction of decreasing as the washing progresses, and the turbidity level of the liquid changes. It was not possible to detect different permeability during both washing and rinsing.
そこで本発明は以上の問題点に鑑みて成された

It provides something that can be detected.

Reference numeral 1 denotes a washing machine main body, and 2 a washing tub, which is composed of an outer case 3 and an inner tank 4 into which laundry is put.The outer case 3 is suspended and supported by a suspension 5 on the washing machine main body 1. Further, a large number of small holes are bored in the peripheral wall of the inner tank 4. Reference numeral 6 denotes a box-like detection case made of a translucent (for example, transparent) material, which is disposed at the bottom of the outer tank 3. As shown in FIG. The light-emitting element 7 and the light-receiving element 8 are disposed facing each other, and the washing liquid and the rinsing liquid can freely enter and exit between the light-emitting element 7 and the light-receiving element 8.
前記発光素子７と受光素子８とから成る検出器

構成されている。 First, on the light emitting element 7 side, a switch 10 is connected in series so that a current limiting resistor R A or R B (where R B > R A ) is inserted in series, and a constant DC voltage is applied between terminals A 1 and A 2 . V 1 is applied, and on the light receiving element 8 side, the light receiving element 8 and a resistor R C are connected in series, and the terminal voltage of the resistor R C is outputted as an output voltage V 2 .
次に動作について説明する。 Next, the operation will be explained.
洗濯物を内槽４に投入して洗濯工程を開始する

いてはすすぎ回数が進むに連れて液の透過度が高
くなり、出力電圧V2は減少する。そして透過度
が一定値以上になり、出力電圧V2が一定値以下
に達した所ですすぎ工程を終了させる。 When laundry is put into the inner tub 4 to start the washing process, light emitted from the light emitting element 7 in the detection case 6 passes through the washing liquid and is projected onto the light receiving element 8. As washing progresses, the washing liquid becomes cloudy and its permeability decreases, causing a change in the value of the output voltage V2 . There, the dirt is removed, the transmittance becomes constant, and the washing process is ended when the output voltage V 2 reaches a constant value. In the rinsing step, as the number of rinses increases, the permeability of the liquid increases and the output voltage V 2 decreases. The rinsing step is then terminated when the transmittance reaches a certain value or more and the output voltage V 2 reaches a certain value or less.

行うことが可能である。 However, the relationship between the output voltage V2 and the turbidity of the detector 9 is as shown in FIG. 6, for example. That is, when the turbidity is high (the liquid is dirty and the permeability is low), the output voltage V 2 is high, and when the turbidity is low (the liquid is clean and the permeability is high), the output voltage V 2 is low. Generally, a detector is required that can detect up to about 500 ppm in the washing process, and less than about 50 ppm in the rinsing process. Therefore, if a detector suitable for detecting the washing process as shown in FIG. 6 above is used to detect the rinsing process, the output voltage V 2 will be
As shown in characteristic a in the figure, it is small and difficult to detect the end of the rinsing process. Therefore, in the present invention, the switch 10 is connected to the A side in the washing process, and connected to the B side in the rinsing process to change the current limiting resistor. As a result, it is possible to obtain the characteristic a shown in FIG. 7 in the washing process, and the characteristic b shown in FIG. 7 in the rinsing process. That is, 1 consisting of a light emitting element 7 and a light receiving element 8
Although only one set of detectors 9 is provided, by monitoring the output voltage V2 , it is possible to detect with high precision the turbidity that is significantly different between the washing liquid and the rinsing liquid, and to determine the end of the washing process and the beginning of the rinsing process. It is possible to perform both detections of termination.

Although the characteristics of the detector 9 were changed by changing the amount of light emitted,
The same effect can be obtained even if the configuration is such that the ratio of the amount of light received on the light emitting element side is changed as shown in FIGS. 4 and 5.
