As shown in Publication No. 72693, the user selects whether the laundry is "heavily soiled,""normallysoiled," or "lightly soiled," and the initial amount of detergent to be added is determined based on the result and the amount of laundry. During the subsequent washing process, if the dirt sensor determines that the laundry has not been sufficiently removed, it will be determined whether the laundry is heavily soiled or
The amount of additional detergent to be added was determined based on the user's selection of ``standard'' and ``light stains.''

制（財）するようにしたものである。Problems to be Solved by the Invention However, in the above-mentioned operating method, the user has to look at the laundry, judge the level of dirt by himself, and input the data, which makes this series of operations cumbersome. There was an issue. In addition, there are large individual differences in determining the degree of soiling, so if there is laundry that is hardly soiled, but there is laundry that is heavily soiled with oil, mud, fruit juice, etc. Some users choose. The amount of detergent put in at this time is rather large, and if the dirt sensor determines that dirt removal is insufficient, more detergent is added, which leads to wasted detergent and further increases the amount of dirty domestic wastewater. Ta. Therefore, the present invention solves the above-mentioned conventional problems by detecting the degree of dirtiness of the laundry and automatically washing the laundry, reducing the initial amount of detergent added and selecting the most suitable detergent according to the degree of dirtiness of the laundry. A first means of the present invention to solve the problem is to realize a control device for a washing machine that saves the amount of detergent used.
A light sensor for detecting turbidity at night, a cloth amount sensor for detecting the amount of laundry, and a control means for inputting the outputs of the light sensor and the cloth amount sensor to control the detergent dispensing device. Based on the output data of the amount sensor, the amount of detergent input at the beginning of the washing process is made smaller than the standard amount, and the amount of additional detergent input is controlled according to the turbidity of the liquid in the tank detected by the optical sensor. This is how it was done.

制御するようにしたものである。In addition to the configuration of the first means, the second means of the present invention is equipped with an operation display section for setting or changing the amount of detergent to be added, and the amount of detergent to be added at the initial stage of the washing process can be controlled by the above-mentioned operation. The additional amount of detergent to be added is controlled in accordance with the turbidity of the gamma night inside the tank, which is detected by the optical sensor.

The output of the optical sensor is inputted to the side tilting means that controls the detergent injection device, the amount of air bubbles mixed in the armpit is determined, and depending on the amount of air bubbles, the amount of detergent is increased or decreased or additional injection is stopped. This is what I did.

量の洗剤の自動追加投入が可能となる。According to the first means of the present invention, the amount of laundry and the turbidity of the liquid in the tank are automatically detected by the amount sensor and the optical sensor,
Since the amount of detergent added is smaller than the standard amount at the beginning of the washing process, it is possible to automatically add an optimal amount of detergent depending on the amount of laundry and the degree of soiling.

量に関係なく最適量の洗剤の自動追加投入が可能とｉる
。According to the second means of the present invention, since the amount of detergent to be added can be set or changed using the operation display section, it is possible to artificially set the amount of detergent to be added at the initial stage of the washing process.
The actual initial amount of detergent added is smaller than the amount set on the operation display, and the amount of additional detergent added is determined based on the amount of laundry detected by the cloth amount sensor and optical sensor and the turbidity of the tank at night. is controlled, so it is possible to automatically add the optimum amount of detergent regardless of the artificially set amount of detergent to be added.

が可能となる。According to the third method, when a large number of air bubbles are mixed into the tank during stirring, it is a sign that there is less dirt. Control the amount of detergent added near the end of the wash process, such as reducing the additional amount of detergent depending on the amount of air bubbles and stopping the additional amount of detergent when the amount of air bubbles exceeds a preset amount. It becomes possible to control the stop automatically.

These values were determined during the first rinse water supply in the previous wash. To explain this simply, first turn on the water supply valve 12 to start water supply, then turn on the drain valve 1o for a predetermined time ( For example, turn it on for 5 seconds).

■ユが低いほど濁度が大きく汚れが大きいと判定する。This is to discharge the bubbles generated during the previous intermediate dehydration. Next, it is determined whether the water level is a predetermined minimum level, and then the output voltage V of the optical sensor 13 is determined. The PWM value and SW value are adjusted so that U becomes the reference value v0. This is the light emission output control or sensitivity adjustment of the optical sensor. These values are then transferred to the storage means 21. Now, step 1
After turning on the water supply valve 12 to start water supply at step 02, the water level sensor 8 determines whether the bi low water level has been reached at step 103, and the water supply valve is turned off at step 104. In step 105, the amount of laundry is detected by the cloth amount detection circuit 18, and thereafter the water level and water flow are controlled to be appropriate for the amount of laundry. In step 106, the detergent dosing device 14 is used to dispense the minimum amount of detergent (60 to 80% of the standard amount of detergent) according to the amount of cloth.
control. After turning on the water supply valve 12 in step 107 and restarting the water supply, in step 108, the water level sensor 8 determines whether the set water level determined by the cloth amount determination in step 105 has been reached. If so, the water supply valve 12 is turned off in step 109, and then the process moves to step 110 to start washing and stirring. This is shown in FIG. 4. Washing starts at time T1, and as washing progresses, dirt on the laundry dissolves in the washing liquid and becomes cloudy, and the pressure voltage of the optical sensor 13 decreases. Step 111 to Step 11
3, during the rest period after stirring for a predetermined time (e.g. 3 minutes) (
For example, the output voltage value of the optical sensor 13 after 5 minutes is detected and the voltages at this time are vl, v2. V3...as vn,

だけ給水弁をＯＮする。During stirring, the turbidity increases due to the influence of bubbles, so the turbidity is detected during the rest period. Step 113 calculates the turbidity change (for example, V3-v2), and in step 114 it is determined whether the turbidity change is less than a predetermined value, and if Y, step 115
The amount of detergent added is added according to the turbidity (or turbidity change). At step 116, the water supply valve is turned on as long as necessary to add detergent.

In steps 201 and 202, the maximum and minimum values of the sensor signals are calculated to detect the amount of foam. If the difference between the maximum value and the minimum value of the sensor signal is larger than the first set value, the amount of detergent added is reduced, and if it is greater than the second set value, the detergent injection is stopped.
