するものである。FIG. 1 is a diagram showing a cross-sectional configuration of a washing machine according to an embodiment of the present invention. In the figure, 1 is the main body of the washing machine, 2 is a washing tub (outer tub) elastically suspended by a suspension 4, and 3 is a washing tub (inner tub) for washing and dehydrating laundry, with numerous water drains on the side of the surrounding wall. It has a hole 6 for use. A pulsator 13 is provided at the bottom of the inner tank 3, and is rotated by a drive motor 8 via a manufacturer case 7 containing a brake and clutch mechanism. Furthermore, a set of light emitters 11. The receivers 12 are disposed facing each other as shown in FIG. 2, and are used to detect washing liquid containing a mixture of water supplied from a water supply hose 14 and a detergent solution from a detergent dissolving section 15 that dissolves detergent in advance with a certain amount of water. It detects the light transmittance and outputs it to the calculation control section 16.

れたバランサである。In addition, 10 is a drainage hose, which is controlled to communicate with the outer tank 2 via a drainage valve 9. Moreover, 5 is a balancer provided at the upper part of the inner tank 3.

汚染発生のおそれを検知して所要の処理を実行する機能
を有するものである。Further, in FIG. 1, the arithmetic control unit 16 is composed of, for example, a microcomputer that controls the operation of the entire washing machine, and in particular, it detects dirt in the washing liquid based on the light transmittance of the washing liquid detected by the light receiver 12. It has a function of detecting the state, detecting the risk of re-contamination based on this, and executing the necessary processing.
次に、再汚染発生のおそれの検出原理を第3図および第
4図を用いて説明する。Next, the principle of detecting the possibility of recontamination will be explained with reference to FIGS. 3 and 4.
再メケ染は、洗濯液の汚れの程度がひどいために洗濯液
中の汚れが洗濯物に移ることであるので、洗濯液の汚れ
状態から再汚染のおそれの有無を判別できるはずである
。すなわち、汚れの程度がひとくなる程、洗濯液の光透
過率が低下することに鑑みて、前記受光器12からの光
透過率の検出結果から洗濯液の汚れ状態を検知し、これ
に基づいて再汚染のおそれを判別するのである。Re-meke dyeing is when the laundry liquid is so dirty that the stains in the washing liquid are transferred to the laundry, so it should be possible to determine whether there is a risk of re-contamination from the soiling condition of the washing liquid. That is, considering that the light transmittance of the washing liquid decreases as the degree of dirt increases, the state of the washing liquid is detected based on the detection result of the light transmittance from the light receiver 12. The risk of re-contamination is determined by
具体的には、洗濯開始の初期段階(洗濯開始から一定時
間to経過後)において、洗濯液の光透過率V1が既に
基準レベルV。I以下のときには再汚染のおそれがある
と判断するのである(第3図の曲線B)。すなわち、洗
濯開始後の初期段階で洗濯液が既に基準レベルを越えて
汚れている場合、それ以上の洗濯の継続は有効ではなく
却って再汚染のおそれがあると考えられるからである。Specifically, at the initial stage of the start of washing (after a certain period of time has passed since the start of washing), the light transmittance V1 of the washing liquid is already at the reference level V. When it is less than I, it is determined that there is a risk of recontamination (curve B in Figure 3). In other words, if the washing liquid is already contaminated beyond the standard level at an early stage after the start of washing, it is considered that continuing the washing further is not effective and may cause re-contamination.
なお、この場合、特に光透過率の検出時刻を設定するこ
となく、洗濯工程中に光透過率が所定の基準レベル以下
に達したときには再汚染のおそれがあるとの判断方法を
採ってもよい。In this case, a method may be adopted in which it is determined that there is a risk of re-contamination when the light transmittance reaches a predetermined reference level or less during the washing process, without setting a specific detection time for the light transmittance. .
別の方法としては、洗濯開始から所定時間(to)内に
おける光透過率の低下率△VIが基準低下率Δv01よ
りも大きいときには再汚染のおそれありと判断するので
ある。すなわち、洗濯開始後の洗濯液における光透過率
の低下率が基準低下率より大きければ、洗濯液の汚れが
間もなく再汚染の発生し得る程に汚れることが予想され
るためである(第4図の曲線B)。なお、この場合にも
、特に光透過率の低下率を算出するための所定時間tQ
を洗濯開始時から設定することなく、洗濯工程中の任意
の時間から設定し、その時の低下率が基準低下率より大
きくなったときには再汚染のおそれがあるとの判断方法
を採ってもよい。Another method is to determine that there is a risk of recontamination when the rate of decrease in light transmittance ΔVI within a predetermined time (to) from the start of washing is greater than the reference rate of decrease Δv01. In other words, if the rate of decrease in light transmittance in the washing liquid after the start of washing is greater than the standard rate of decrease, it is expected that the laundry liquid will soon become so dirty that recontamination may occur (Figure 4). curve B). Also in this case, the predetermined time tQ for calculating the rate of decrease in light transmittance is
Instead of being set from the start of washing, it may be set from any time during the washing process, and when the rate of decrease at that time becomes greater than the standard rate of decrease, it may be determined that there is a risk of re-contamination.
次に、本実施例における再汚染防止のための作用を第5
図に示す演算制御部16の処理フローチヤードを用いて
説明する。なお、再汚染のおそれの判別方法としては、
前述した第4図の方法とする。Next, the action for preventing recontamination in this example will be explained in the fifth section.
The process will be explained using the process flowchart of the calculation control unit 16 shown in the figure. The method for determining the risk of recontamination is as follows:
The method shown in FIG. 4 described above is used.
洗濯開始前に予め洗濯液の光透過率を検出した」二で洗
濯が開始されてから一定時間to経過時の受光器12か
らの出力に基づいて低下率△V1を求め、予め設定され
ている基準低下率△V1と比較して上述した如く再汚染
のおそれの有無を判断する(ステップ100〜140)
。The light transmittance of the washing liquid was detected in advance before the start of washing.The reduction rate ΔV1 is calculated based on the output from the light receiver 12 after a certain period of time has passed since the start of washing, and is set in advance. It is compared with the standard reduction rate △V1 to determine whether there is a risk of recontamination as described above (steps 100 to 140).
.
判断の結果、△Vl <△Vo1であり再汚染のおそれ

ある場合には、直ちに洗濯を中止して排水弁9を開動作
させて洗濯液を排水して再汚染の発生を止めると共に、
新たな洗濯液を給水して最初から再び洗濯を開始させる
(ステップ]50、 160)。特に、この場合、排出
は給水しながら行うのが好ましい。As a result of the judgment, if △Vl < △Vo1 and there is no risk of re-contamination, washing will proceed according to the normal process (step 170); however, if △V1≧△V01 and there is a risk of re-contamination, washing will be carried out immediately. stop and open the drain valve 9 to drain the washing liquid and stop the occurrence of re-contamination.
A new washing liquid is supplied and washing is restarted from the beginning (steps 50 and 160). Particularly in this case, it is preferable to discharge while supplying water.

Since the clothes are washed with washing liquid, re-contamination can be reliably prevented without placing any burden on the user.
