The present invention relates to a washing administration selection method of a washing machine, and more particularly, to a method for a user to smoothly select a display unit using a rotary switch.

Conventionally, as shown in FIG. 1, when power is applied, a light emitting diode (LED) is turned on in a standard, and a user selects a washing stroke.

The entire large administration is special, reservation, soaking, water supply, water level, washing, rinsing, dehydration, and there are 4, 8, 10, 12 as sub-categories for special, standard, strong, delicate, blanket, and sub-categories for reservation. There are 1, 2, and 3 subcategories for soaking, and there are separate subcategories for the other major categories.

In the conventional case, if you want to wash the laundry strongly, select the reservation time of 8, the soaking time of 3, and the hot water of hot / cold water, select strong in the large category, turn the rotary switch, and then go through all the small categories in the major category, blanket, etc. We then entered a major category reservation and selected 3 through subclasses 1 and 2 in the reservation.

In other words, even though one subclass in the major category is selected, the user has to be uncomfortable because the subclasses in the next major category must be selected through the subclass in order.

In order to solve the above problems, when one subclass is selected within a major category, an object of the present invention is to proceed to the next major category without going through another subclass in the major category.

The present invention for achieving the above object will be described in detail with reference to the accompanying drawings.

First, FIG. 2 shows a circuit diagram of a rotary switch as an overall block configuration of a washing machine according to the present invention. The configuration is a microcomputer driving power supply unit 10 for driving a microcomputer in the washing machine, and a recess of the rotary switch to facilitate rotation. (2), the execution key (3) for selecting the sub-menu display portion flashing according to the left and right rotation, the rotary switch 40 located in the center portion, and the key input section for selecting each stroke of the washing by the push button ( 20) and an elliptical menu display unit 70 in which the main menus and sub-menus of respective strokes using the light-emitting diodes are turned on, flashing, and turned off according to the signals input from the key input unit 20 and the rotary switch 40;

A load unit 50 connected to a washing motor rotated according to the washing stroke displayed on the menu display unit 70, a sensor unit 30 for detecting a washing state at the washing stroke, and an error in the washing stroke. It is composed of an alarm unit 60 for generating an alarm signal when generated and a microcomputer 80 for controlling the overall operation of each circuit unit.

According to the hardware configuration described above, the washing stroke selection method according to the present invention divides each stroke of the washing machine into a large category and a small category corresponding to the large category as shown in FIG. 5, and only one of the small classes is selected. When the user wants to change the small category automatically selected by the selection of one of the small categories, the user selects the small category by pressing the execution key in the small category in the desired large category. If you want to change the subclass selection step to select, and if you want to change the subclass in another major category after selecting the subclass, rotate the rotary switch to move to the next major category without going through the unselected subclass in the first major category, and then cancel the subclass. When you want to Sub Category includes clear steps to cancel again by pressing the Run key in the position of the classification.

In addition, when the user rotates the rotary switch in the large category moving step, the selected large class of light emitting diodes (LED) is turned on, the selected small class of LEDs are flickered, and the selected large class of LEDs is turned on.

The rotary switch 1 is rotatable to quickly select the desired stroke as shown in FIGS. 3 and 4 in order to display the washing stroke with the light emitting diodes, and the recessed part 2 to which the rotary switch is conveniently rotated. ), An execution key 3 for selecting a submenu light emitting diode flashing on the display unit at the center position of the rotary switch 1, a main menu selected by the rotary switch 1 and the execution key 3, and An ellipse in which each light emitting diode is operated in accordance with an operation / pause key (4) for executing or stopping a submenu stroke and the rotary switch (1), execution key (3), and operation / pause key (4). Is composed of a menu display section (5).

4 is a detailed diagram of the elliptical menu display unit 5 is a main menu display unit (special, reservation, soaking, water supply, water level, washing, rinsing, dehydration) 5a and submenu display unit (anticorrosion) , Standard, strong, blanket, delicate, 4, 8, 10, 12, 123, cold water, hot and cold water, hot water, minimum… medium, steel, medium, weak) (5b).

The operation, operation, and effect of the present invention thus made will be described with reference to FIGS. 3 and 4.

In the state of initializing the microcomputer (step S1), it is determined whether there is a previously learned function of the washing machine (step S2), and if there is a learned function (see (7) in Table 1), the special light emitting diode of the main menu display part 5a Is turned on, the anti-corrosive bladder diode of the sub-menu display section 5b blinks, and each light emitting diode of the learned stroke blinks (step S3).

In this way, after each LED is turned on and flashing, the user presses (or selects) the direct operation / pause key 4 without pressing the execution key 3 (step S4). After this is executed, it ends (step S5).

On the other hand, if there is no function learned in the above (step S2), as shown in Table 1 (7), the special, water supply, water level, washing, rinsing, dehydration light emitting diode of the main menu display unit 5a lights up, the sub-menu display unit ( If the user presses the operation / pause key 4 after blinking the standard cold water light emitting diode of 5b) (step S8), the washing process of the standard course is executed (step S9).

However, if the user does not press the operation / pause key (steps S4 and S8), the microcomputer 80 searches whether the rotary switch is rotated left and right (steps S6 and S10), and the main menu of the stroke to be selected corresponding to the number of rotations. The display section 5a is turned on and the submenu display section 5b at the current position flashes (step S11).

At this time, if the user rotates the rotary switch once to the right twice, the course is changed to strong as shown in (1) of Table 1, and the large and small category light emitting diodes (LED) suitable for the course are selected and the right one time again. Rotate once to turn on the blanket as shown in (2) of Table 1 and turn on the light emitting diode (LED) according to the course. If it is rotated two times again, it is the same as (1) of Table 1 and if it is rotated seven times, it is like (4) of Table 1, and if it is rotated seven times, the water level light emitting diode of the main menu display part (5a) is shown as (1). Is lit, the light emitting diode of the sub-menu display part 5b is blinking, and when it is rotated once more, the light emitting diode is turned off and the 0 light emitting diode is blinking.

And, if rotated to the right once more, the water level light emitting diode is turned on and the high light emitting diode blinks.

After the main menu light emitting diode of the selected washing administration and the submenu light emitting diode of the current position are blinked (step S11), the selected submenu light emitting diode is lighted when the execution key is pressed (step S13).

At this time, when the execution key is pressed once more, the selected submenu LED is turned off (cancelled), and the submenu and related submenu of the current position are also turned off, and the next submenu LED is blinking.

If the operation / pause key is selected after pressing (selecting) the execution key in step S13, step S14) turns on (automatically selects) the submenu light emitting diode of the stroke to be selected (step S15), and if not selected, rotates the rotary switch. The main menu light emitting diodes of which the number of steps has been changed (moved) light up, and the provisional submenu light emitting diodes flash (step S17). This means the movement between the main menu LEDs according to the left and right rotation speed of the rotary switch.

As an example of this, as shown in FIG. 4, the cold water light emitting diode is turned on when the execution key is pressed in cold water and the rotary switch is rotated to the right once in the cold water of the submenu display 5b in the water supply of the main menu 5a. The water level light emitting diode of the display portion 5a is turned on, and the light emitting diode of the submenu display portion 5b belonging to the water level blinks.

That is, when the submenu stroke in each main menu display section is pressed with the execution key and the rotary switch is rotated, the submenu light emitting diode in the other main menu display section 5a flashes according to one movement.

On the other hand, after performing the step S17, if the execution key is selected, the main menu light emitting diode and the sub-menu light emitting diode of the laundry administration selected in the previous step S17 is turned on (step S19), when the operation / pause key is selected above ( After the washing administration of all the selected submenus is performed (steps S20 and S21), the process ends.

As described above, according to the present invention, the user selects a sub-menu administration in the main menu display unit of the washing machine as an execution key and then lights the next main menu light emitting diode as the rotary switch is rotated, and the temporary submenu light emitting diode in the main menu is turned on. By blinking, the microcomputer can be easily controlled, so that each stroke of the washing machine can be easily selected.
