In FIG. 1, 1 is a washing tub for storing laundry and washing water, and 2 is an outer tub for storing washing water. 3 is a pulsator for stirring laundry and washing water, which is rotated by a motor 4 via a belt 5. A controller 6 controls the water supply device 7, the drainage device 8, the dirt sensor 9 and the motor 4. A fuzzy reasoner 10 determines the washing time from the value detected by the dirt sensor 9. In this embodiment, a microcomputer is used for the controller and the fuzzy reasoner, and an optical sensor is used for the dirt sensor.

に達するとモータ4を停止する。Next, the operating principle of the dirt sensor 9 will be described. FIG. 2 is a block diagram of the dirt sensor 9, in which the drive circuit 12 is connected to the drain port 11.
The light emitting unit 13 whose light emission amount changes depending on the supply voltage from the light receiving unit 14 and the light receiving unit 14 whose output voltage changes depending on the light receiving amount are provided to face each other. The output voltage of the light receiving unit 14 is amplified by the amplifier circuit 15. With this configuration, the light from the light emitting unit 12 is received by the light receiving unit 13. However, the light transmittance changes depending on how dirty the washing water is at the drain port 11. That is, the amount of dirt in the wash water can be known from the output voltage of the light receiving unit 14 (hereinafter referred to as the transmittance). The change in transmittance from the start of washing is as shown in FIG.
That is, the permeability at the start of washing is V 1 , and as the washing progresses, the stains on the washing water become more severe and the permeability becomes smaller.
Stabilizes at V 2 . That is, the amount of dirt in the wash water becomes saturated. At this time, V 2 represents the amount of stains on the laundry, and T represents the stain resistance (hereinafter referred to as stain quality). Considering that the pre-rinseed product can be cleaned cleanly without waste, the washing effect is determined by the washing time when the washing water flow is constant. Therefore, it is considered to determine the optimum washing time based on the above-mentioned transparency and saturation time. Although it has been stated that the permeability and the saturation time represent the amount of stains and the quality of stains on the laundry, it is difficult to formulate the washing time from these variables because it depends largely on the feeling and experience of the user. Therefore, by expressing the general know-how of the user in a fuzzy relationship, an appropriate washing time is determined by fuzzy inference. The controller 6, which has received the wash time as the result of this inference, stops the motor 4 when that time is reached.

る。Next, the fuzzy reasoner 10 used in this embodiment will be described. First, as for the structure of the antecedent part, as shown in FIG. 4, the two-input space formed by the transparency and the saturation time was fuzzy divided into four regions, and rules were set for each region. The membership function used is monotonic (F1 (V), F2) in both transmittance and saturation time, as shown in Figs.

Labeled short and long. The consequent part is a two-variable linear format based on the transparency and saturation time (Yi (V, T) i = 1 to 4)
And Therefore, the completed rule is as follows.

First, at the same time as washing starts, the counter is started to capture the initial transparency. Then, after waiting for a certain period of time, the transmittance is taken again and compared with the initial transmittance, and if the difference is less than a certain value, the process proceeds to the next step (the transmittance at this time is V 2 ). If not, the transparency taken in the second time is replaced with the initial transparency, and waiting for a certain period of time is repeated. In the next step, the counter value is read and the saturation time is set to T. Enter fuzzy reasoning below. First V 2 · T
More grades for each membership function (G1 ~
G4). Next, one grade (g1 to g4) is calculated for each rule by the MINIMUM operation. In this way, the consequent part of the rule is weighted by the saturation time T, the transparency V2, and the grade (G1 to G4) obtained from the membership function of the antecedent part. Then, the weighted conclusions of the rules are combined, and the center of gravity Y of the combined result is calculated. Finally, the counter values Y are compared and if they are equal, the motor 4
To stop the washing process.

得られる。The inference result by the fuzzy inference unit 10 is shown in FIG.
As you can see from the figure, the inference result is a non-linear plane. Normally, the soil condition and the washing time are considered to have a linear relationship from the viewpoint of removing stains, but the above relationship becomes non-linear when factors such as wanting to reduce cloth mess and economic efficiency are added to the viewpoint. This can be easily understood from the fact that if the washing time is prolonged, the stains will be removed well, but the cloth will be damaged and the economy will be uneconomical. The fuzzy reasoner determines the washing time, taking these factors into consideration, so that the optimum washing time can be obtained.
