(To) is the wash key, and the washing time during the washing process is changed from 12 minutes to 6 minutes to 3 minutes to none each time the key is operated. (The plow is a rinsing key, and the number of rinsing processes (drainage - intermediate dehydration - water supply - rinsing) is changed every time the key is pressed from 2 times - 1 to none. (7) is the dewatering key, and every time the key is pressed, Change the dehydration time in the dehydration process to 6 minutes - 3 minutes - 1 minute - None.Furthermore, LEDs 511 to 6m correspond to numbers other than "None", and 'None' is displayed as off. The rinsing time during the process was 2 minutes. (The washing, rinsing and dehydration key numbers were collectively referred to as the operation keys).

(Incorporated) uses a water flow key that changes the reversal cycle of the rotor blade (6) from "Strong" to "Soft" to "Standard" each time the key is operated. The LEDs (to) to (sub) correspond to the display characters of each water flow, and the 1 (to) that lights up and displays is the careful rinse key, which changes the type of rinsing in the rinsing process from normal to rinsing. This setting is for water injection rinsing, which increases the rinsing effect, and switches between water injection and no water injection each time a key is pressed. The LED @ lights up when water is being poured, and is off during normal rinsing.゛■ is the start key for the "Speedy course" which is set to 6 minutes of washing, 2 times of rinsing, and 3 minutes of dehydration. be. This secondary start key also serves as the start key for the "favorite course" that allows you to select and set washing, spin-drying time, and number of rinses as appropriate. The column is a stop key to temporarily stop each process.

Further, corresponding to the three courses, an LEDI 31- (to) is provided to indicate the operating status of the course.

The rinsing time in the "Speedy course" is 1 minute per rinse, and the strength of the water flow is a strong water flow.

The washing machine is operated by sequentially moving through washing, rinsing, and spin-drying steps according to the programs of each course.

Next, this driving operation will be explained. First, when you close the power switch knob (21), the microcomputer ■ will be reset, and before any other key operation, one of the Start Keys (Incorporated) will be fully operated, and one of the corresponding LED II (Incorporated) will be activated. lights up. For example, when the "standard course" is selected, fully automatic operation starts, and all the LEDs corresponding to the washing, rinsing, and spin-drying keys (to) (41 (to)) light up.

On the other hand, the wash key (machine, rinse key, or dehydration key (7) is operated before the start key tIBlB1),
After that, when the start key is operated, the "favorite course" according to the user's key settings will start. In this case, as shown in FIG. 2(b), only the LEDs corresponding to the LEDs @~- are lit for a shorter time (less number of times) than the LEDs set.

Note that changing operations using the water flow key (F) and the thorough rinse key (TO) can be accepted without operating the stop key. Changing operations using the wash key decoy, rinse key decoy, and dewatered buffalo-1 are accepted while being temporarily stopped by the strib key transfer.

In this way, when the fully automatic operation of 1 "Standard Course" has started, in the washing process, first open the water supply valve (18) to supply water. (O trips (ON') L, closes the water supply valve (2),
The rotor (6) rotates with the set water flow.

Rinsing in the rinsing process is similar to washing in the washing process, but
If the thorough rinse key is operated, the water supply valve (to)
This consists of rinsing by pouring water while leaving the door open.

Intermediate dehydration during the rinsing process and final dehydration during the spin-drying process begin when the water is drained and the liquid level switch (@ is reset (OFF)), the washing tub (3) is rotated clockwise, and the clothes in the tub are removed by centrifugal force. After the entire process is completed, the drain valve Ql is closed.

When draining water during the rinsing and dewatering steps, there are cases where the drain hose (2) is forgotten or the drain channel αD is clogged and the water cannot be drained. In this case, the liquid level switch (turn) will reset (OF) even if 3 minutes have passed after starting draining.
F)l, if there is none, it is determined that there is a drainage abnormality, and all of the course display LEDs @'f), , , - flash, and the abnormality buzzer sounds for a certain period of time (25 times in this example) to display the abnormality. Notify the user by doing so. If the stop key is operated in this state, the abnormality display will be canceled.

That is, since the abnormal display is canceled by using the process as a temporary stop means, it is possible to restart the process after correcting the abnormal location and changing the process time as appropriate. In other words, the laundry may be recontaminated during a drainage abnormality, but it is possible to start washing again by using the method described in the first example.

Now, the LEDs 51) to 51 corresponding to the washing key 2, the rinsing key, and the dehydration key turn off one by one as each process progresses and the corresponding time and number of times have elapsed.
All lights are turned off at the end of the course.

Further, the LED of the start key of the corresponding course also turns off at the end of the course.

If you operate the S)g key while each of the above steps is in progress or an abnormality is displayed, each step will be temporarily stopped and each step of the above L E p (stl-1) will be stopped as shown in FIG. The paused state is indicated by lighting only the LED indicating the longest time (number of times) during the pause.

In this embodiment, when setting the time for each process of washing, rinsing, and dehydration, as described above, each time you operate the operation key The highest level is sequentially moved to the lowest level, and the above-mentioned pause state also adopts a similar display form. Therefore, the settings and changes of each process time are displayed in the same manner, and the operation means are very easy to understand.

In addition, an LED (51J~
1. It doesn't bother me because it doesn't flash the haze.

Next, changes in the course midway will be explained based on FIG. 1. However, in this embodiment, only the "standard course" or "speedy course" can be changed to the "preference course". 7. Therefore, the "Standard Course" and "Speedy Course" are hereinafter collectively referred to as the "Special Course."

First, while the "special course" is in operation, the LED of the course is lit as shown in FIG. 1 (b) (the figure shows the case of the "standard course"). If you want to change the "special course" (if you want to change each Zen time), first operate the stop key -, then operate the operation keys (to) to dan for each process time in the -stop state. Change process time. From that point on, the washing machine does not proceed according to the "special course" time program. Therefore, the "special course" is automatically canceled and a new "visiting course" is set. Furthermore, as shown in FIG. 1(c), the LED (133 or 2008) indicating that the ``special course'' is in progress turns off, and the LED 15 indicating the ``favorite course'' turns on.

In this way, when the user makes a good start, the star of the ``r*favorite course'' with LED 5 lit.
All you have to do is operate the i key Im).

In other words, when the course is changed, the LED ■ indicating the course after the change ("favorite course") lights up, and the LP, D@, or (Foundation) indicating the course before the change turns off, so you can restart the game. The user will not be confused when

Note that the LEDs corresponding to each course light up to display the current course at the time of temporary stop, and switch to display the changed course at the time the process time is changed. Additionally, when restarting, operating the start key for a course whose LED is off will not be accepted.

1) Effects of the Invention According to the present invention, when the operating course of the washing machine is changed by changing the process time of the operating course while the operating course is in progress, the display means automatically switches the display to the operating course after the change. Therefore, in the subsequent operation process of the washing machine, the user can recognize that the operating course has been changed.
□ Operability can be improved without making mistakes.
