BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully automatic washing machine, and in particular, to control a fully automatic washing machine having a function of conversation with a user who operates by changing standard table values necessary for the operation algorithm of the whole washing machine. It is about a method.

Hereinafter, a conventional washing machine will be described with reference to the accompanying drawings.

In general, the washing machine adjusts the water level to multiple stages (5 stages, 7 stages, etc.) according to the washing capacity.

The water level determination of the washing machine is the same as in FIG. 1, which is a flowchart showing the water level determination operation of the conventional washing machine.

First, it is determined whether the user has selected the water level (100) and if the user has selected the water level, water is supplied accordingly. Otherwise, water supply is performed to the decimal point to detect the amount of water (101).

Subsequently, the number of dose pulses according to the quantity detection is recognized (103) to determine the water level (103).

Subsequently, water is supplied by selecting the water level such as the low water level 104, the low water level 105, the low and low water level 106, the medium water level 107, the used water level 108, the high water level 109, etc. according to the water level determination. (110).

Then, it is determined whether water supply is made up to a specified level according to the water level determination (111) to perform a washing function (112).

2 shows the water flow pattern of the conventional washing machine, and shows the operation waveform of the washing blade during washing and rinsing according to the water level.

The higher the water level (the more the amount of laundry), the higher the running rate (the ON time ratio of the washing blades), and the lower the the water level (the less the amount of the laundry), the lower the running rate.

In other words, the high rate of operation

to be.

Next, referring to FIG. 3 (a), which is a circuit configuration diagram of a conventional washing machine, and FIG. 3 (b), which is a waveform diagram showing a conventional laundry washing machine, is described below. same.

The driving of the washing motor consists of the ON-OFF switching operation of the TRACs TR1 and TR2, which are the most suitable elements for opening and closing of an AC circuit capable of controlling current in both directions by flowing a current through one gate.

The above TR1 and TR2 are controlled by the P54 and P55 ports of the microcomputer.

When the washing motor is switched from ON to OFF, residual rotation is performed by inertia rotational power. If the amount of laundry in the washing tank is large, friction between the laundry and the washing blade increases, and the residual rotation speed is drastically reduced.

As described above, the number of pulses of the waveform is reduced as shown in FIG.

On the contrary, if the amount of laundry is small, the friction of the washing blade is small, and the inertia rotation of the washing motor is increased, thereby increasing the pulse number.

The pulse level is detected at the microcomputer's P62 port to determine the wash level.

In this case, as shown in FIG. Is the opposite end of the motor in FIG. ) Shows the voltage waveform of Denote both ends of the photo coupler of FIG. ) Shows the output waveform of Of FIG. 3 (a) It shows the waveform applied to the microcomputer's P62 input port at both ends.

The water level detection and washing operation of the washing machine will be described in detail as follows.

If the high signal is output from the microcomputer's P54 port during current detection, current is applied to the base of the transistor Q ₄ in FIG. 3 (a). Therefore, the collector-emitter of the transistor Q ₄ is turned on. On), and the trigger signal is applied to the gate of TR1 to turn ON between T _{1 and} T ₂ so that the motor is supplied with AC 110 / 220V voltage to the left turn coil so that the motor rotates to the left and LOW signal is applied to P54. When applied, transistor Q ₄ is turned off and between T _{1 and} T _{2 of} TR ₁ is turned off so that the motor rotates by inertia rotational power.

The right turn control is controlled in the same manner as above using the P55 port.

At this time, the level is determined by the number of pulses applied to the P55 port of the microcomputer during the inertia rotation.

During the washing operation, the rotation control of the motor is made of the output of the HIGH-LOW signal of the P54 and P55 ports as described above, and the applied waveform is changed according to the determined water level.

It is an object of the present invention to provide a control method of a fully automatic washing machine having a function.

In order to achieve the above object, the control method of the automatic washing machine according to the present invention includes determining whether a signal regarding a dissatisfaction of the washing machine stroke is input by a user's selection and reading a satisfaction factor value of the corresponding washing stroke; Determining the level of the signal and differentially adding or subtracting the satisfaction factor value according to the signal level, storing the adjusted factor value and determining a standard table value required for the corresponding stroke according to the signal level; It is characterized in that it comprises a step of storing and performing the function of the administration.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the control method of the automatic washing machine of the present invention.

And a water level display section and a reservation key. And the user opinion reflection selection unit is configured as an input means unit for achieving the purpose of reflecting the user's requirements of the present invention to the stroke of the washing machine.

And, as shown in FIG. 6, which is a block diagram of the washing machine of the present invention, E ² PROM, which is a non-volatile memory device, is used to store data according to the user's requirements using the user's opinion reflection selector of FIG. Satisfaction function unit 65 is additionally configured and the display unit 61 for displaying the contents of the washing administration, the water level, the reservation time and the user's satisfaction using the user's opinion reflection selection unit under the control of the microcomputer 60, and the washing administration and the user.

In FIG. 6, the E ² PROM memory storage unit of the satisfaction function unit 65 as shown in FIG. 8 is a configuration diagram of the E ² PROM operation storage unit of the washing machine of the present invention. Satisfaction storage unit, which is a data storage unit in which total satisfaction is accumulated when reflecting satisfaction in an item, and an operation storage unit that stores table values related to the washing algorithm determined according to the overall satisfaction evaluation of the operation results of the washing machines used so far. .

Satisfaction storage unit stores the user's satisfaction by the whole process of washing, tangles, rinsing, dehydration, wrinkles, etc., motion storage unit washing time, water flow pattern, water level, rinsing frequency, rinsing of the operation algorithm of the washing machine Stores data on patterns, dehydration times, rinsing water height, washing water level, etc.

In addition, FIG. 9, which is a diagram illustrating the control factor correlation of the washing machine of the present invention, describes all factors in association with factors that have a major effect, although all factors have a slight effect on each performance.

In particular, washing power and entanglement, dehydration and wrinkles are factors influencing each other.

Referring to the operation and control method of the fully automatic washing machine of the present invention as described above are as follows.

10 is a flow chart showing the operation of the satisfaction function unit of the present invention, and Fig. 11 (a) (b) (c) is a flow chart showing the operation and control method of rinsing, washing and dehydration, respectively.

Automatic washing machine of the present invention is that the algorithms of the washing machine operation change according to the user's satisfaction, first, the 10-degree control operation rinsing, the user and relates to dissatisfaction on the E ² PR OM satisfactory storage unit in each operation washing, dehydration When the signal is stored, it is interrupted during each process to convert the standard table value of each algorithm stored in the microcomputer 60 of the washing machine, and reads the factor value of the E ² PROM satisfaction storage unit of the corresponding process. In step 201, the dissatisfaction level of the user input through the user opinion reflection selection unit is determined (202).

Then, the satisfaction factor value of FIG. 7 is gradually increased or decreased according to the level of dissatisfaction determined in the step.

That is, if the dissatisfaction of the user is "slightly dissatisfied", +1 increases in the case of washing and dehydration, and decreases by -1 in the case of entanglement and wrinkles (203).

If the dissatisfaction of the user is "very dissatisfied", +2 increases in the case of washing and dehydration, and -2 decreases in the case of tangle and wrinkles (204).

Subsequently, the satisfaction factor value adjusted to reflect the dissatisfaction of the user as described above is stored in the E ² PROM to terminate the interrupt operation (205) (RTS: Return From Sub routine).

Next, the rinsing stroke of FIG. 11 (a) will be described.

In the rinsing operation, first, the user's rinsing data stored in the rinsing satisfaction portion of the satisfaction function unit 65 is read to determine whether the user's satisfaction is satisfied (200).

If the user is satisfied in the previous washing process, the standard table value necessary for the rinsing stored in the E ² PROM operation storage unit is read without changing the standard table value of the washing algorithm (208) and the rinsing function is performed (209).

However, if the user does not satisfy the rinsing state, the satisfaction function unit 65 obtains a new factor value by reflecting the user's opinion by the algorithm shown in FIG.

Then, the table value (water height, frequency, water flow pattern) necessary for rinsing is adjusted upward according to the factor value obtained by the satisfaction function unit 65 (206), and the corrected table value is stored in the E ² PROM operation storage unit ( 207, thereby performing a rinse function (209).

Then, as shown in FIG. 11 (b), the washing administration reads data related to the washing of the user stored in the washing satisfaction unit of the satisfaction function unit 65 to determine whether the washing is satisfied (210).

Subsequently, it is determined whether the user satisfies the tangle state in the previous washing process (211) (212) If the washing and tangling are both dissatisfied, the satisfaction function unit 65 obtains a new factor value according to the dissatisfaction level (213).

After determining the table value (water height, time, water flow pattern) required for washing and tangling according to the factor value obtained by the satisfaction function unit 65 (216) and storing the determined table value in the E ² PROM operation storage unit. The washing function is performed based on the newly determined table value (221).

In step 210 and 211, if the tangled state is satisfied and the washing state is determined to be unsatisfactory, the satisfaction function unit 65 obtains a new factor value according to the dissatisfaction level of the washing state of the user (214).

Next, the table value (water height, time, water flow pattern) required for washing is adjusted upward according to the factor value obtained by the satisfaction function unit 65 (217).

The table value adjusted as described above is stored in the E ² PROM operation storage unit (220) and then the washing function is performed (221).

In step 210 and 212, if it is determined that the washing state is satisfactory and the tangle state is not satisfied, the satisfaction function unit 65 obtains a new factor value according to the dissatisfaction level of the user's tangle state (215).

Then, the table value (water level, time, water flow pattern, etc.) required for washing is adjusted downward according to the factor value obtained by the satisfaction function unit 65 (because washing power and entanglement are control factors having a large influence on each other) (219 ).

The determined table value is stored in the E ² PROM operation storage unit (220) and then the washing function is performed (221).

In step 210 and step 212, if the state of both washing and entanglement is determined to be satisfied, the standard table value required for washing stored in the E ² PROM operation storage unit is read (218) to perform the washing function (221).

Then, as shown in FIG. 11C, the dehydration administration reads data related to dehydration of the user stored in the dehydration satisfaction section of the satisfaction function unit 65 to determine whether it is satisfactory (230).

Subsequently, it is determined whether the user satisfies the wrinkle state in the previous washing process (231). If both the dehydration and the wrinkle are unsatisfactory, the satisfaction function unit 65 obtains a new factor value according to the dissatisfaction level (233).

Next, a table value necessary for dehydration and wrinkle is determined according to the new factor value (236).

Then, the determined table value is stored in the E ² PROM operation storage unit (239) and the dehydration function is performed (241).

In step 230 and 231, if the wrinkle state is satisfied and the dehydration state is determined to be unsatisfactory, the satisfaction function unit 65 obtains a new factor value according to the dissatisfaction level of the user's dehydration state (234).

Next, the table value (time, etc.) related to dehydration is adjusted upward according to the factor value obtained by the satisfaction function unit 65 (237).

The stored table value is stored in the E ² PROM operation storage unit (239) and the dehydration function is performed (241).

In addition, the table value adjusted upward is stored in the E ² PROM operation storage unit (239), and then a dehydration function is performed (241).

If it is determined that the dehydration state is satisfactory and the wrinkle state is unsatisfactory in the 230 and 232 steps, the satisfaction function unit 65 obtains a new factor value according to the degree of dissatisfaction of the user's wrinkle state (235).

Then, the table value (time, etc.) related to dehydration is adjusted downward in accordance with the factor value obtained by the satisfaction function unit 65 (because dehydration and wrinkles are control factors having opposite effects to each other).

Subsequently, the determined table value is stored in the E ² PROM operation storage unit (239) and the dehydration function is performed (241).

In step 230 and 232, if dehydration and wrinkle state are satisfied, the standard table values related to dehydration stored in the E ² PROM operation storage unit are read (240) and the dehydration function is performed (241).

As described above, the control method of the automatic washing machine according to the present invention realizes an interactive laundry system in which a user's opinion inputted using a user's opinion reflection selection unit of the washing machine is reflected in the washing machine operation algorithm, thereby washing by the whole washing machine. The state of rinsing, dehydration, etc. is controlled in the direction desired by the user, thereby increasing the user's satisfaction and convenience.
