【発明の詳細な説明】
（技術分野）
本発明は洗浄液の濁度を検出して該濁度変化に
より洗濯動作を制御する洗濯機に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a washing machine that detects the turbidity of a washing liquid and controls washing operations based on the change in turbidity.
（従来技術）
従来、この種の洗濯機にあつては、特開昭57−
66793号公報等に見られるように、洗濯動作の初
期において濁度検出器の感度をその時の洗浄液の
濁度に応じ自動調整することにより、洗浄液の濁
度変化を正確に検出できるようになつている。(Prior art) Conventionally, this type of washing machine was disclosed in Japanese Patent Application Laid-Open No.
As seen in Publication No. 66793, it has become possible to accurately detect changes in the turbidity of the cleaning liquid by automatically adjusting the sensitivity of the turbidity detector according to the turbidity of the cleaning liquid at the beginning of the washing operation. There is.
ところで、このような従来の洗濯機では、洗濯
動作の途中で一時停止して再運転した場合には濁
度検出器の感度を再調整しない為、一時停止し
て、新たに汚れた洗濯物を投入し再運転した場合
等において洗濯終了を正確に検知することができ
ず、洗濯物の汚れが充分に落ちないうちに洗濯動
作が終了するという不都合を招く虞れがあつた。 By the way, in conventional washing machines like this, when the washing operation is temporarily stopped and restarted, the sensitivity of the turbidity detector is not readjusted, so the washing machine stops temporarily and restarts the washing process. When the machine is loaded and restarted, it is not possible to accurately detect the end of washing, and there is a risk that the washing operation may end before the laundry is sufficiently cleansed.
（目的）
本発明はかかる点に鑑みてなされたもので、洗
濯動作の途中で一時停止して再運転した時に濁度
検出器の感度を再度自動調整することにより、従
来の如き不都合を解消するものである。(Purpose) The present invention has been made in view of the above points, and aims to eliminate the inconveniences of the conventional method by automatically adjusting the sensitivity of the turbidity detector again when the washing operation is stopped temporarily and restarted. It is something.

以下図面に示した本発明の実施例について詳細
に説明する。(Example) Examples of the present invention shown in the drawings will be described in detail below.

一時停止手段である。 FIG. 1 is a block diagram showing a control system of a washing machine according to an embodiment of the present invention. In Figure 1, 1
2 is an outer tank, 2 is a cleaning liquid, 3 is an inner tank, 4 is a pulsator, 5 is a communication tube, 6 is a turbidity detector that optically detects the turbidity of the cleaning liquid by a combination of a light emitting element and a light receiving element, and 7 is a turbidity detector. A conductive pipe for draining the cleaning liquid in the tank via the drain valve 11, 8 a motor, 9 a motor control section, 10 a memory function for storing detected values from the turbidity detector 6, and a temporal control of the detected values. It has a calculation function to calculate the change, a function to judge the end of the operation by determining that the temporal change in the detected value has become below a certain predetermined value, a sensitivity adjustment function to adjust the sensitivity of the turbidity detector 6, etc. A turbidity determination section, 11 a drain valve, 12 a drain valve control section, 13 a sequence control section, and 14 a temporary stop means.
上記構成において、洗浄液はパルセータ４の回
転により、矢印のように内槽３→外槽１→連通管
５→導通管７→外槽１→内槽３の順で循環し、濁
度検出器６を通過する時にその濁度が検出され
る。 In the above configuration, as the pulsator 4 rotates, the cleaning liquid circulates in the order of the arrow: inner tank 3 → outer tank 1 → communication pipe 5 → conduction pipe 7 → outer tank 1 → inner tank 3, and the turbidity detector 6 Its turbidity is detected as it passes through the water.
次に、その制御について第２図の動作説明図に
従い説明する。今、内槽３内に洗濯物を投入して
モータ８を駆動し、洗濯動作が開始すると、先ず
初期段階において濁度検出器６の感度がその時の
洗浄液の濁度に応じ自動調整される。そして、洗
濯動作が進み、洗浄液の濁度の時間変化がある所
定値以下に低下すると、洗濯終了を判定して洗濯
動作を停止する。 Next, the control will be explained with reference to the operational diagram of FIG. 2. Now, when laundry is put into the inner tub 3 and the motor 8 is driven to start the washing operation, the sensitivity of the turbidity detector 6 is automatically adjusted in the initial stage according to the turbidity of the cleaning liquid at that time. Then, as the washing operation progresses and when the turbidity of the cleaning liquid decreases over time to a certain predetermined value or less, it is determined that the washing has ended and the washing operation is stopped.
このような洗濯動作の途中において、一時停止
手段１４から停止信号が入ると、洗濯動作が中断
する。そして、新たに汚れた洗濯物が投入されて
運転が再開されると、この時点で濁度検出器６は
その時の洗浄液の濁度に応じて感度が再度自動調
整されることになる。従つて、その後の洗浄液の
濁度変化を正確に検出することができ、洗濯終了
を正確に判定することができる。 During such a washing operation, when a stop signal is input from the temporary stop means 14, the washing operation is interrupted. Then, when new dirty laundry is put in and the operation is restarted, the sensitivity of the turbidity detector 6 is automatically adjusted again according to the turbidity of the cleaning liquid at that time. Therefore, subsequent changes in the turbidity of the washing liquid can be accurately detected, and the end of washing can be accurately determined.
尚、すすぎ動作時においては、一時停止されて
も汚れた洗濯物が新たに投入されることが殆どな
い為、濁度検出器６の感度再調整は行なわない。 Note that during the rinsing operation, the sensitivity of the turbidity detector 6 is not readjusted because new dirty laundry is hardly ever put in even if the rinsing operation is temporarily stopped.

不都合を解消することができる。(Effects) As described above, according to the present invention, by automatically adjusting the sensitivity of the turbidity detector again when the washing operation is stopped temporarily and then restarted, the laundry that became dirty during the pause can be removed. It is possible to accurately detect the end of the washing operation at the point where the washing machine has been loaded, and the inconveniences of the conventional methods can be solved.
