The present invention relates to the rinsing control of the washing machine to make a rinsing process to automatically perform one rinsing to be selected according to the consumer's preferences, in particular, by setting the rinsing automatic additional course, the user further rinsing once the washing operation is completed The present invention relates to a method for controlling a rinsing function of a washing machine to further increase the rinsing performance and simplify the key operation.

As shown in FIG. 1, the circuit configuration of a general washing machine includes a key input unit 1 for selecting a desired washing stroke by pressing a key in various states such as washing, rinsing, dehydration, and washing time, and the key input unit. In accordance with the output signal of (1), the microcomputer 2 for controlling the overall operation of the washing machine and the input AC power AC are converted into constant voltages of a predetermined level to supply operating power to the microcomputer 2 and the necessary parts. The output terminal P8- of the microcomputer 2 is composed of a power supply unit 5 to supply, a switching unit 3a, an array resistor 3b, a triac TR1-TR5, and a capacitor C1-C5. When P12 is at each high potential, the outputs of the switching section 3a and the array resistor 3b become high potential, and a trigger signal is applied to the gates of the triacs TR1-TR5 to supply the cold water supply valve CV and the hot water supply valve ( A load driver 3 for controlling driving of the HV, the motor M1, and the magnet MG, and The display unit 4 displays various states such as washing, rinsing, dehydration, and washing time according to the control signal of the microcomputer 2, and a clock signal to the microcomputer 2 using an oscillation signal having an oscillation frequency of 4 MHz. An oscillation section 8 for providing a signal, a reset section 9 for initializing the microcomputer 2 at power on / off, and an interrupt generator section for detecting an zero crossing at a commercial frequency to generate an interrupt signal; (6) and a buzzer sound generating unit (7) for inputting a control signal of the microcomputer (2) to generate an alarm when the washing machine is inoperative.

Looking at the conventional technology configured as described above are as follows.

In the state where the constant current source rectified by the power supply unit 5 and the clock generated from the oscillation unit 8 are applied to the microcomputer 2, the user may perform washing, rinsing, and dehydration of the key input unit 1. Press each key to set washing 5 minutes, rinsing 2 times, dehydration 2 minutes, and then pause the operation. When the key is pressed, the microcomputer 2 reads the key signal of the key input unit 1, and then its output terminal ( P8, P9) to output high potential.

The high potential is applied to the gates of the triacs TR5 and TR4 through the switching unit 3a and the array resistor 3b configured in the load driver 3, so that the triacs TR5 and TR4 are turned on. The hot water feed valve HI and the cold water feed valve CI are opened to supply hot water and cold water to the washing tank.

Then, when water is supplied to a predetermined level in the washing tank, the microcomputer 2 outputs a high potential signal to its output terminal P12 for 5 minutes designated by the user, and the high potential signal is converted into its switching unit 3a and the array. After the resistor 3b is turned on, the triac TR1 is turned on to rotate the motor M1 counterclockwise.

Thereafter, a low potential signal is output from the output terminals P11 and P12 of the microcomputer 2 to pause the motor M1 for a predetermined time, and then a high potential signal is output from the output terminal P11 of the microcomputer 2. The motor M1 rotates in a clockwise direction by being turned on and then turning on the triac TR2 through the switching unit 3a and the array resistor 3b.

As described above, the high potential and the low potential are repeatedly outputted alternately at the output terminals P11 and P12 of the microcomputer 2 to proceed with washing for the entire washing time.

In this way, when washing is completed, the process enters the rinsing process. Before entering the rinsing process, the microcomputer 2 controls the drain valve to turn on to discharge the dirty water during washing, and when the draining is completed, the switching unit 3a and After rotating the motor M1 through the array resistor 3b to perform intermittent dehydration, the dehydration is performed by changing the rotational speed again. The dehydration speed is accelerated at an appropriate speed according to the quantity and the quality of the dehydration.

When dehydration is completed in the same way as described above, after a certain period of time, the water enters the rinsing stroke, and when rinsing, the drain valve is turned on again to supply water and then rinsing. Let's see.

When selecting the number of rinses, as shown in (a) of FIG. 2, each time the rinsing key K1 is pressed, the number of rinses is increased to the number of rinses 1,2,3,4 on the rinse count display unit LED1 and the rinse count display unit is further pressed. LED1 increases the number of rinses 1,2,3,4, and the water supply lamp LP1 lights up to indicate the water supply rinsing.

That is, the total number of times that the rinsing key K1 can be pressed is rinsing 1,2,3,4 and water supply rinsing 1,2,3,4 as shown in FIG. Returning to the rinse 1 state is repeated.

For example, when the user selects two rinses, drainage → intermittent dewatering → dehydration → rest → water supply → rinsing to complete the rinsing process once, and then draining → intermittent dewatering → dehydration → rest → water supply → rinsing. Rinse twice.

In the case of rinsing three or more times, the above-described process is repeated.

When the rinsing process is performed with the fabric softener, the fabric softener in the softener case 10 of FIG. 4 (b) is increased in room 1 (when the rotational force of the washing tank is increased during intermittent dewatering → dehydration. 10a) and then stop the washing tank with a stop time and then dehydrate again to control the acceleration twice so that the fabric softener in the softener case 10 passes well beyond room 2 (10b). → Proceed with rinsing so that the fabric softener penetrates the cloth well.

As such, when the rinse stroke is added only once with the fabric softener, it is different from the rinse stroke without the softener added once.

In the case of performing two rinses with the fabric softener, the fabric softener in the softener case 10 of FIG. 4 is increased when the rotational force of the washing tank is increased during intermittent dewatering during the first rinsing stroke. The fabric softener in room 1 was moved to room 1 (10a), and afterwards, the rotation of the washing tank stopped, the water supply was finished, and the rinsing was completed. Proceed to 2 (10b).

After the dehydration, the fabric softener, which was in Room 2 during the rest period, flows down into the washing tank through the hole 10c, and the softener penetrates the cloth during the rinsing process.

In general, the washing process of washing machine is generally performed in the order of washing → rinsing → dehydration stroke, and the user selects each washing step such as when washing, rinsing, dehydration key is used to select only washing or dehydration only. Can be used.

However, in the conventional technique as described above, when the rinse is selected three times, the softening agent penetrated into the cloth in the second rinse is released from the intermittent dehydration → dehydration process of the third rinse stroke, so the effect of the fabric softener is rapidly decreased. In the case of four rinses, the above process is repeated twice, which is the same as the effect of the fabric softener.

Therefore, when rinsing 3, 4 times is selected to compensate for the decrease in the effectiveness of the fabric softener, the intermittent dehydration → dehydration → when the rinse is performed twice or two or three times, the fabric softener effect is excellent, but the rinsing performance is reduced. There are many consumers dissatisfied with.

If you are not satisfied with the rinsing performance after the completion of the washing, since the rinsing again by selecting a separate rinse once, there is a problem that waste of time, water, electricity, etc. required for the washing administration.

Therefore, an object of the present invention for solving the conventional problems is to provide a rinsing automatic addition key when the key is pressed when the rinsing force to automatically proceed once the rinsing once the normal course washing → rinsing → dehydration is completed It is to provide a method of controlling the rinsing function of the washing machine to increase the.

Another object of the present invention is a purge, wool, blanket, soaking, rapid course and the rinsing function control method of the washing machine to add a rinse automatic addition function to each of these courses to select 10 courses to vary the consumer choice In providing.

The present invention for achieving the above object is a first step of checking whether the automatic rinsing course is selected when the power is applied, and if the automatic rinsing course is not selected in the first step proceeds to the selected course and if selected automatic mode A second step of checking whether it is a manual mode or a third step of detecting an amount of laundry and selecting a water level according to the detected laundry if the automatic mode is used in the second step, and water supply according to the water level in the third step A fifth step of performing washing, rinsing, and dehydrating stroke upon completion, and a fifth step of automatically setting water and rinsing one time at the completion of each stroke in the fourth step, and generating a buzzer sound informing the input of the fabric softener; Waiting for a predetermined time to add the fabric softener in the fifth step to perform a rinsing stroke and to end after draining, dehydrating stroke, and if the manual mode in the second step again dedicated The seventh step of checking whether the mode is the mode; and if the user does not use the dedicated mode in the seventh step, the user selects the water level and proceeds to the fourth step; in the dedicated mode, performs only the selected stroke, and then proceeds to the eighth step. Is done.

Referring to the operation and effect of the present invention for the method consisting of each step as described above in detail as follows.

When power is supplied from the power supply unit 5 to the microcomputer 2 and the necessary parts, the microcomputer 2 controls the display unit 4 so that the purge LED is first turned on in the washing machine operation display unit as shown in FIG. do.

At this time, each time the course key is pressed, the automatic rinsing stroke is lit as one independent course in the order of purge → automatic rinse → wool → blanket → soaking → rapid.

Alternatively, as in Figure 6, each time you press the course key once, Purge → Wool → Blanket → Soaking → Rapid → Auto rinse + Purge → Auto rinse + Wool → Auto rinse + Blanket → Auto rinse → Soak → Automatic Rinse → Rapid Rinse Addition is not added as an independent course, but is added to each of the five existing courses.

At this time, when the user selects the automatic rinsing function as an independent course, the microcomputer 2 recognizes this and checks whether the automatic mode or the manual mode is selected. In the automatic mode, the amount of laundry not shown is detected and the level is determined according to the detected laundry. After selecting, through the output terminal (P8-P12) through the switching unit (3a) and the array resistor (3b) to control the hot water feed valve (HI), cold water feed valve (CI) and the motor (MI) appropriately Proceeds first, and proceeds to the rinsing stroke and dehydration stroke, and when the dehydration stroke is completed, the rinse is set automatically once.

When the rinsing time is automatically set, the microcomputer 2 outputs a control signal to the output terminals P8-P12 again and supplies water, and then drives the buzzer sound generating unit 7 informing the input of the fabric softener. Let them listen.

The consumer waits for a certain time to put the fabric softener and proceeds with the rinsing stroke. When the rinsing is completed, the drainage, dehydration, and rest stop after the end sound.

In the manual mode instead of the automatic mode, it is determined whether the dedicated mode is again. If the consumer does not select the water level manually and presses the temporary operation key, the microcomputer 2 controls the load driver 3. As in the automatic mode, the process proceeds to washing, rinsing, and dehydrating.

In the dedicated mode, when the consumer selects the desired stroke, the microcomputer 2 automatically sets the water level to the medium level, and then determines whether the washing administration is selected. If only the rinse stroke is selected, only the rinse stroke, and if only the dehydration stroke is selected, only the dehydration stroke is performed and then ends.

In addition, when selecting the rinse automatic addition + purge of the 10 courses as shown in FIG. 10, the rinsing is automatically performed once all the strokes are completed after washing → rinsing → dehydration, which is a general washing course.

That is, as shown in FIG. 7, after all of the washing administration and drainage, intermittent dehydration, dehydration, rest, water supply, and rinsing rinsing administration and drainage, intermittent dehydration, dehydration, and rest that are finished, One additional rinse will proceed.

As described in detail above, the present invention aims to improve the function by rinsing the automatic rinsing function once, and increases the rinsing performance by using the automatic rinsing course for the consumers who are dissatisfied with the rinsing performance and also adds the fabric softener. In addition, when necessary, and when the additional rinse is often used, the operation is very simple and convenient.
