除き公知のものと同様である。 DESCRIPTION OF THE PREFERRED EMBODIMENTS A case will be described below as an example in which the present invention is applied to a well-known dehydrating and washing machine controlled by an electronic circuit. FIG. 1 shows the basic structure of a washing machine with dehydrating function. In FIG. 1, reference numeral 1 denotes an outer box, inside of which a water receiving tank 2 serving as a washing tub is suspended by an elastic support mechanism 3, and a stirring blade 5 is provided inside the outer box. 6 is a washing machine motor that selectively drives the rotating tub 4 and the stirring blades 5. 7
2 is a sampling chamber provided in a water receiving tank 2 so that cleaning water can pass therethrough, and as shown in FIG. A light-receiving element 11 such as a transistor is arranged to face the light-receiving element 11 . On the other hand, an electronic control circuit 12, which is a control circuit device shown in FIG. Processing unit (CPU) 14, clock control circuit 15,
It is composed of a memory 16, an input buffer control circuit 17, an output buffer control circuit 18, and an AD converter (analog-to-digital converter) 19. In the external input section A, 20 is a power switch that supplies power to the entire device, 21 is a program selection switch for selecting the combination of strokes, and 22 is a rotating tank 4.
A safety switch 23 is a lid switch for detecting abnormal vibrations of the safety switch 23, and each of these states is converted into logical values 0 and 1 by state conversion elements 24 to 27 such as flip-flop circuits, respectively. Further, the external input section A also includes a transparency detection device 28 that forms a part of the transparency detection means 9, and this transparency detection device 28 detects the amount of light received by the light receiving element 11 from the light emitting element 10. The output signal S1 is supplied to the input buffer control circuit 17 after being digitally converted by the A-D converter 19. . In the external output section B, 29 is a water supply valve as a constant water supply source, 30 is a drain valve, 6 is the washing machine motor, and 31 and 32 are an indicator lamp and an alarm, respectively, to notify the end of the washing machine operation. Each section in the external output section B is controlled to be energized by switching elements 33 to 37 such as thyristors. The arithmetic processing unit 14 reads the states of the state conversion elements 24 to 27 corresponding to the states of each part in the external input section A via the input buffer control circuit 17, and also reads the process data from the memory 16. , washing (including water supply), draining, rinsing, (including water supply), dehydration, notification, etc. External output unit B necessary to judge and execute the process
Each part inside is controlled by applying signals from the output buffer control circuit 18 to the switching elements 33 to 37, and the control method is a transparency detection method to detect the degree of rinsing or the degree of dirt on the laundry. The device 28 is similar to known devices except that it also serves to control the water supply prior to washing and rinsing.

ことができる。 Therefore, the water supply control by the arithmetic processing unit 14 is performed as explained below. That is, during water supply, the arithmetic processing unit 14 issues an operation command to the switching element 33 to operate the water supply valve 29 to start supplying water into the water receiving tank 2, and also measures the water supply time from the time when water supply starts. When the water level in the water receiving tank 2 reaches the transparency detection means 9 position, that is, the sampling chamber 7 due to this water supply, the light receiving element 11 transfers the light from the light emitting element 10, which had been received through the air, to the air. Since the light is received through cleaning water having a different light transmittance from that of the water, the transparency detection device 28 changes the value of its output signal S1, and the water level in the water receiving tank 2 changes to the sampling chamber 7 due to the change. Determine what has been achieved.
Then, the arithmetic processing unit 14 outputs the output signal S1.
The above-mentioned time measurement is stopped in response to the change in the input buffer control circuit 17 through the A-D converter 19 and the input buffer control circuit 17, and the time from the start of water supply until the water level in the water receiving tank 2 reaches the sampling chamber 7 is calculated. Measure it as a reference time and read out a constant, for example, "3" stored in advance in the memory 16, and continue to issue an operation command to the switching element 33 for a time obtained by multiplying the reference time by this constant "3",
After that, the operation command is stopped. Therefore, water supply valve 2
After the water level in the water tank 2 reaches the sampling chamber 7, the system 9 continues to supply water to the water tank 2 by operating for three times the time required to supply water up to that water level. In this way, water is supplied to the predetermined water level in the water tank 2. In the above case, if the value of the constant read out from the memory 16 by the arithmetic processing unit 14 is configured so that the user can vary it arbitrarily and in multiple steps, the operation time of the water supply valve 29 can be arbitrarily varied. Therefore, the water level in the water receiving tank 2 can be set in multiple stages according to the amount of laundry to be washed. Furthermore, if the constants read out from the memory 16 by the arithmetic processing unit 14 are different at each time of water supply prior to washing and rinsing,
The amount of water supplied during washing and rinsing can be made different.
