た。24. A fully automatic washing machine that automatically performs each step such as spin-drying is operated for a fixed period of time using a time switch. -1. Also, when it comes to laundry, the user judges the amount of laundry and how dirty it is, and then sets the time on a time switch. This makes it difficult to wash, rinse, and dehydrate the laundry in an appropriate manner for the amount and soiling of the laundry. Therefore, a detector consisting of a light-emitting element and a light-receiving element is installed at the bottom of the washing tub, and the change in light transmittance from the light-emitting element to the light-receiving element is detected during each process of washing, rinsing, draining, spin-drying, etc. The idea was to control the washing machine by detecting the end of the process.
しかしながら、洗濯機は屋内、屋外等、様々な所で使用
されるのが通例であり、特に洗濯機を屋外で使用する場
合には、発光素子から発光される光以外の光が受光素子
に入ってしまい、的確な透過率の変化の検出が行えない
という問題点があった。However, washing machines are usually used in various places such as indoors and outdoors, and especially when washing machines are used outdoors, light other than the light emitted from the light emitting element enters the light receiving element. Therefore, there was a problem in that it was not possible to accurately detect changes in transmittance.
本発明は上記従来の問題を解決するものであり、以下、

ター１７が封入にて装着しである。FIG. 3 shows the details of the detector 12, 16 is a light emitting element made of, for example, a light emitting diode, 16 is a light receiving element made of, for example, a phototransistor, and the drainage path 1o is interposed between them. A filter 17 for attenuating visible light is sealed and mounted on at least the surface of the light receiving element 16 among the elements 15 and 16.
上記構成において、次に作用を説明する。洗濯。In the above configuration, the operation will be explained next. laundry.
脱水、排水等の行程終了は、検出器１２を取り付けた排
水経路１ｏにおいて、洗濯、すすぎ、排水。At the end of the process of dewatering, draining, etc., washing, rinsing, and draining are carried out in the drain path 1o to which the detector 12 is attached.
脱水の各行程時に、発光素子１６より発光し排水 。During each step of dewatering, the light emitting element 16 emits light and drains water.

等の各行程の終了検出ができなくなる。The end point is detected by detecting a change in the transmittance of the light transmitted through the path 10i to detect a change in turbidity of the washing liquid, rinsing liquid, etc. For example, if strong light enters the light-receiving element 16 when washing outside the store 66 - where there is strong external light, even if there is a change in the turbidity of the washing liquid, rinsing liquid, etc. in the drainage path 10, the As a result, the transmittance becomes abnormally large due to characteristic A in Figure 4, making it impossible to accurately detect the end of each process such as washing, rinsing, draining, and spin-drying. It disappears.

ことができる。However, by providing the covers 13 and 14 and further providing the filter 17 for attenuating visible light, it is possible to prevent the light receiving element 16 from receiving external light, and as shown in characteristic B in FIG. Changes in turbidity of washing liquid, rinsing liquid, etc. in path 1° can be accurately detected by changes in light transmittance.
It is possible to detect the end of washing, rinsing, draining, and spin-drying without accidentally wiping.
