The present invention relates to a method and apparatus for a reserved laundry machine of a washing machine, and more particularly, to perform a reserved laundry by inputting a reservation key without inputting a current key. There is a purpose.

1 is a configuration diagram of a conventional laundry washing apparatus for a washing machine, and includes a key operating unit 1 for inputting an operation and time to be washed, and a microcomputer 2 for receiving a signal from the key operating unit and outputting a control signal. And a first switching device 3 for supplying 5V of power to the key manipulation unit 1 according to a signal applied to a terminal connected to the microcomputer, and the key manipulation unit 1 input and processed to the microcomputer 2. And a second switching unit 4 for supplying power to the display unit 5 by being switched according to the signal of (), and a display unit 5 for displaying contents input by the power supplied from the second switching unit. The operation unit 1 consists of first to fourth diodes D1 to D4 and their respective switches SW1 to SW4.

Referring to FIG. 1 and FIG. 2 attached to the reservation washing operation of the conventional washing machine configured as described above are as follows.

The microcomputer 1 sends a LOW signal to only one port at regular intervals to the 20th to 23rd ports P20 to P23, and at the same time, numbers are assigned to the 0th to 6th output ports P00 to P06. It will export data that can represent.

For example, when it is desired to display "12: 34" on the display of the display unit 5, the microcomputer outputs a low signal to the 20th port P20 and the 0th to 6th ports P00 to P06 as shown in FIG. (c) outputs data corresponding to " 2 " and then outputs a low signal to the twenty-first to twenty-third ports P21 to P23, and at the same time to " 3 " to the 0 to sixth ports P00 to P06. , "4", "1" to output the data to display the number.

Next, the operation of the key operation unit 1 will be described.

When the microcomputer 2 outputs a low signal to the twentieth port P20, 5V is supplied through the first diode D1. At this time, if the first switch SW1 is pressed, the 60th port of the micom ( The high signal is applied to P60), and the microcomputer recognizes that the "current key" is input.

By operating the key in such an operation, it is possible to perform reservation laundry as in the flowchart of FIG.

First, press the "Current Key", press the "Hour" and "Min" keys to set the current time, then press the "Reservation Key" and press the "Hour" and "Min" keys to perform the reservation laundry course.

However, if the user presses the operation / pause key after setting the current time while performing the reservation laundry, the user immediately enters the general washing course. Therefore, the user first enters the current time and then sets the reservation time later. Next, you can enter the reservation course by pressing the operation / pause key. If you press "current key" or "reservation key", you can check the set time.

However, such a conventional laundry washing machine has been inconvenient in use by operating with four keys, and the current time is confirmed after setting the current and reservation time due to the immature or misuse of the key operation, or other For this reason, if the current key is pressed and the action / pause key is pressed, the user enters the general laundry course, unlike the user's intention to proceed with the reservation course. Therefore, there is a problem in that the reservation course must be set again.

Accordingly, an object of the present invention is to solve the above-mentioned troublesome use and complicated use problems.

Such a method for achieving the object of the present invention comprises the steps of determining whether or not the "reservation" key input, storing the input reservation laundry time, and if the reservation laundry time is a predetermined number of times the scheduled laundry time It can be achieved by determining and storing the washing trend for the step, and if you do not want to set a separate reservation washing time, the step of performing the reservation laundry as the stored reserved laundry trend data.

In addition, the means for achieving the other object of the present invention is the key operation means for inputting the laundry reservation operation and the washing time, and outputting a control signal to store the washing status input from the key operation means and stored at the same time A reservation input means for inputting a reservation operation to the key operation means, comprising a micom for comparing with the washing status and a storage means for receiving a control signal from the micom, storing the washing status, and reading the stored information; This can be achieved by constructing a time input means for increasing an arbitrary time according to the one-time pressing of.

3 is a configuration diagram of one embodiment of the present invention, a laundry machine 10 for inputting only a laundry time and a minute time, and a microcomputer that receives a signal of the key controller and outputs a control signal ( 20), a first switching device 30 for supplying 5V power to the key manipulation section 10 according to a signal applied to the terminal connected to the micom, and the key manipulation section input and processed to the micom 20 A second switching unit 40 for supplying power by switching in accordance with the signal of (10), a display unit 50 for displaying contents input by the power supplied from the second switching unit, and a microcomputer (from the key operation unit). The key manipulation unit 10 is configured as a learning unit 60 for storing the reservation laundry situation inputted through 20) and reading the stored state under the control of the microcomputer, and the key manipulation unit 10 includes the diodes D ₁ and D ₂ . Its respective switch (SW ₁₎ And SW ₂ ) are connected to each other, and the learning unit 60 is composed of an E-ROM (EEPROM), resistors R ₉ to R ₁₃ , and a power supply. In the above description, the key switch 10 of the first switch SW1 is a "reservation key" and the second switch SW2 is a "bunch key".

Referring to Figures 3 to 5 attached to the operation and effects of the present invention configured as described above are as follows.

First, the microcomputer 20 sends a low signal to only one port at regular intervals from the 20th to 23rd ports P20 to P23.

At the same time, data representing numbers can be output to the 0th to 6th output ports P00 to P06.

For example, to display 07: 00 on the display of the display unit 50, the microcomputer applies a low signal to the 20th port P20 connected to the input terminal of the first switching device MC1417, and the second switching device. Data corresponding to "7" in FIG. 5B is outputted to the 0th through 6th ports P00 through P06 connected to the input terminal of the MC1416P.

Subsequently, a low signal is output to the 21st to 23rd ports P21 to P23, and data corresponding to "0", "0", and "0" is output to the 0th to 6th ports P00 to P06. To display the number.

Since the first switching unit 30 is a transistor array element having a PNP structure, the output is high when the base input is low, and the second switching element 40 is a transistor array element having an NPN structure. The output must be high only when the bass input is high.

On the other hand, if the user wants to perform the reservation laundry, first press the reservation switch (SW) of the key control unit (10).

According to the ON of the reservation switch, the microcomputer detects this and performs the reservation operation.

However, before learning about the initial reservation tendency, 0:00 is displayed on the display as shown in (a) of FIG. 5, and when the user presses the minute / hour display switch SW ₂ of the key control unit 10 once. Therefore, the time increases by 10 minutes.

When the reservation time is set in the above process, the operation / pause key not shown in the drawing is pressed to enter the reservation laundry process to perform the learning.

That is, the reservation time set in the microcomputer 20 is stored in an E-ROM, and as the number of times of reservation washing is increased, the reservation time of the user is frequently stored by comparing and analyzing the reservation experience of the user.

This learning process is explained with an example as follows.

If the user has to finish the reservation washing three or more times after 7 hours, the microcomputer 20 analyzes it and stores it in the E-ROM.

Then, when the reservation key is pressed to perform the reservation washing course, "7: 00" is displayed on the display as shown in (b) of FIG. 5, and pressing the operation / pause key enters the reservation course immediately. If the change is made, the microcomputer will re-analyze the reservation trend and store it in EEPROM.

In this way, the two keys can be used to simply perform a reservation laundry, and the reservation function can be performed immediately without inputting time by identifying the reservation trend through the learning function.

As described in detail above, in the present invention, when performing the conventional reservation washing, after setting both the current time and the reservation time, the user wants to check the current time or presses the present key for another reason and then presses the operation / pause key. Contrary to the purpose of this, by eliminating the problems that proceeded to the general laundry course, there is an effect that can be performed by a simple operation without reservation.
