[Detailed Description of the Invention] Industrial Application Field The present invention detects the permeability of washing liquid using an optical sensor,
The present invention relates to a washing machine control device that automatically controls washing time based on the amount of change.

BACKGROUND OF THE INVENTION Conventionally, a washing machine that uses this type of optical sensor to detect transmittance and determine washing time has been controlled as shown in FIG. That is, the vertical axis of the graph in FIG. 4 shows the transmittance, and the horizontal axis shows the washing time. Instant drainage is performed after a certain time (tl) from the start of washing in the graph, and a reference value (vl) is set by the optical sensor 3. After that, every predetermined time (12,
13...tn), the transmittance of the washing liquid is detected by the optical sensor (v2.v3...vn). When washing begins, as dirt from the laundry is removed, the washing liquid becomes cloudy, and eventually the permeability reaches a saturated state.

That is, in FIG. 5, 12.13. - The amount of change in transmittance at the time of tn (where n≧1) is Δv1. Δv2...Δvn
The straightness is getting smaller. At the saturation point of the degree of turbidity, the amount of change in ΔV, that is, the value of (Δvn−Δvn+1) becomes minute. When this value becomes less than or equal to a set value, it is determined that the washing has finished, and the washing time T is set.

Problems to be Solved by the Invention With such conventional control methods, when a liquid detergent is used, there is a problem that the washing time runs out prematurely. That is, in the conventional control method, when liquid detergent (R) is used,
The washing setting time is T in Figure 4 (,).

(Since the permeability decreases at a constant rate, the amount of change in permeability ΔV is constant), and the washing time at which the cleaning power reaches saturation is shorter than Tp in Figure 4 (,), so there is sufficient cleaning effect. was not obtained.

The reason is explained below. Powder detergent (P) is liquid detergent)
Compared to liquid detergents, the particles are larger and there is a difference in turbidity when mixed with water, and it takes longer than liquid detergents to reach an emulsified state.

洗濯時間の早切れという現象が生じたのであった。
In addition, in the case of powdered detergent (P), at the beginning of the cleaning process,
Since the process of removing dirt to some extent by the action of alkali contributes to cleaning, the initial slope of the permeability curve increases. On the other hand, in liquid detergent (R), the action of the surfactant, which plays an important role in cleaning, largely depends on the washing time. In other words, since the transmittance curve is closer to a straight line than P in Fig. 3, it is difficult to detect the amount of change in ΔV of R.
This caused a phenomenon in which the washing time ran out prematurely.

EXAMPLES Hereinafter, examples of the present invention will be explained using FIGS. 1 to 3. In FIG. 1, a detection means 3 for detecting the permeability of washing liquid is provided at the drain port of a tube 2 of a receiver housing a washing tub 1 having an agitation R7 arranged at its inner bottom. The detection means 3 converts the detected transmittance into a voltage by a first control means 3' comprising an input section, an output section, and an arithmetic control section. The first control means 3' uses this voltage value to drive the motor 6, which drives the stirring blade 7, via the motor drive means 5.

Washing liquid conductivity detection means 4 between the washing tub 1 and the receiver tube 2
determines the type of detergent, and controls the motor drive means 5 by the second control means 4' consisting of an input section, an output section, and an arithmetic control section.
The motor 6 is driven once through. Figure 2 shows the conductivity of tap water and detergent at standard concentration. As is clear from Figure 2, since liquid detergent is non-ionic,
Since aqueous solutions do not conduct electricity, they are significantly different from the highly conductive powder detergents. Therefore, the type of detergent (liquid, powder) is determined based on the conductivity.

The control of the present invention will be explained with reference to FIG. Washing is started in step 8, and after a certain period of time has elapsed, the washing liquid permeability is detected by the permeability detection means 3 in step 9. Next, when the amount of change in transmittance ΔV becomes equal to or less than the set value in step 1o, the end of washing is detected, and then, in step 11, conductivity detection is performed by the conductivity detection means 4, and in step 1
In step 2, it is determined whether the detergent is a liquid detergent or a powder detergent. If it is a powder detergent, the washing process ends in step 11, and if it is a liquid detergent, the washing process ends after the washing time is extended by a predetermined time (minutes) in step 13.
