The present invention relates to a washing machine, and more particularly, to a washing course and an administration index table attached to the lower part of a washing machine lid so that a user can set the washing course and the stroke by using a washing course and an operation channel key as a reference. A course and administration selection apparatus and method are described.

1 is a block diagram illustrating a general washing machine, and includes a key operating unit 1 for various key operations, a display unit 2 for displaying various operating states of the washing machine, and a water level detecting unit 3 for detecting a water level in the washing tank. ), A quantity detecting unit 4 for detecting a quantity of water, a power supply unit 5 for supplying power to each system, a load driving unit 6 and a buzzer driving unit 7 for driving various loads and buzzers, It consists of the microcomputer 8 which controls an operation.

In addition, the key control unit 1 is a water supply button, washing button, rinsing button, dehydration button, water height button and the washing course to be used to manually change the function as shown in FIG. The course selection button to be used, the dehydration button or the buzzer button to be used for dehydration only or to turn off the buzzer, the action / pause button to be used for operation and pause, and the reservation for The present time button, the reservation button, the hour and minute buttons and the like, and the display unit 2 is an LED display unit for displaying the laundry progress state.

Referring to the functional operation selection operation of the general washing machine configured as described above with reference to the flow chart of FIG. 3, first, after the user turns on the power, the washing machine operates as a standard course of the A path unless a separate item is selected.

However, if the user wants to change the course by pressing the course button after the power is turned on, the washing machine moves to the path of B to select a desired course.

On the other hand, if the course button is not pressed, the course of course C is not changed. That is, the user can obtain the desired function by performing the steps (S1-S6) by pressing the respective key as described above, and when all the selection is completed, the user presses the operation / stop key of the key input unit 1 to perform the washing operation Initiation proceeds to the path of D to perform the washing.

However, the conventional washing machine as described above has a disadvantage in that the user is inconvenient and cumbersome when the desired stroke is complicated, and operates by using several keys.

The present invention is to solve this problem, an object of the present invention is to simplify the key operation unit of the washing machine and to attach the course and the administrative index table to the bottom of the lid of the washing machine by using the coarse channel key and the operation channel key with reference to the washing machine It is to provide a course and a stroke selection device and method of the washing machine to facilitate the washing machine operation by allowing the selection of the course and the stroke selection by the channel setting type.

Features of the present invention for achieving the above object is a course index table for assigning a corresponding course to each channel number by setting a plurality of channel numbers, an administrative index table for assigning a corresponding administration to each channel number by setting a plurality of channel numbers and And a course channel key for selecting the course according to the course index table and an operation channel key for selecting the course according to the stroke index table.

According to another aspect of the present invention, there is provided a course and administration selection method for a washing machine, comprising: a first step of selecting a course by pressing a cos channel key and a second step of selecting a detailed stroke by pressing an operation channel key; How to choose

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

4 is a view illustrating a functional operation unit of the washing machine according to the present invention, which simplifies the water height, the water temperature, and the reservation key, and maintains the dehydration key as in the prior art.

And the course, washing, rinsing, dehydration key and display unit were deleted, and course channel key for course selection and operation channel key for each administration selection were added.

When the coarse channel key and the operation channel key are selected, the coarse LED 11 and the coarse LED 12 are turned on. When a reservation is selected, the reservation LED 13 is turned on. 1 hour-24 hours) can be set.

In addition, the reservation time is increased to 1-24 according to the number of presses of the reservation key, wherein the reservation time indicates how long the operation is completed from the present time, and when 7 is selected, the washing machine operation is completed after the next 7 hours. do.

After the channel selection is finished, when the washing machine is operated by pressing the operation / stop key, the remaining time LED 14 is turned on, and the remaining time is changed in units of minutes to indicate 1 to 199 minutes.

0-11 (more than that can be set) is selected according to the number of times the operation channel key is pressed, and 0-5 (more than that can be set) is selected according to the number of pressing the cos channel key. When selecting the course channel key, each function can be selected by referring to the administration and course index tables attached to the bottom of the washing machine lid.

The functional operation control flow of the present invention according to the above configuration of the operation unit will be described with the flowcharts of FIG. 5 showing the operation channel display state and FIGS. 6 and 7 showing the coarse channel display state.

First, when the washing machine power is applied, the washing machine coarse LED 11 and the operation LED 12 are turned on, and the corresponding segment is set to 01.

Referring to FIGS. 5 and 6, it can be seen that washing-rinse twice-dehydrated in the standard course.

If the user operates the washing machine by pressing the operation / stop key without pressing another key, the washing machine proceeds to the path of A of FIG.

On the other hand, if the user changes the course by pressing the cos channel key, the process proceeds to the path of B and changes to 0-5 (or more) depending on the number of times the segment on the top of the course LED is pressed. And the user sets the course with the operation channel key according to the desired course channel. Here, if the coschannel key is not pressed, it is in a standard state, press once to call, press twice to fast, press three times to blanket, press four times to midnight, and press five times to select wool.

At this time, if the user does not press the course channel key, the course proceeds to the path of C and the course is not changed.

On the other hand, if you want to change the stroke, press the operation channel key to set the desired channel of 0-11 (or more).

That is, as shown in FIG. 5, pressing the operation channel key once is the standard state of washing-rinsing twice-dehydrating, pressing twice for dehydration 5 minutes, pressing three times for rinsing once, and pressing four times for soaking-washing-rinsing. 2 times-dehydration, 5 times to wash, 6 times to wash-rinse 2 times, soak 7 times-washing-rinsing 2 times, 8 times to soak-washing, 9 times to rinse 2 times-dehydration, 10 times to wash -Dehydration, press 11 times, soaking, washing, dehydration, etc. are selected.

In other words, as described above, the user can easily select a desired course administration as a channel.

In this method, when the washing machine door is opened, the administrative and course index tables of FIGS. 5 and 6 attached to the bottom of the washing machine door are set, but when the user masters only a few times, it can be conveniently remembered as the channel setting of the TV.

On the other hand, the water level change selection, the water temperature change selection, or the reservation selection after the operation channel selection are the same as before.

As described above, the present invention can significantly simplify the function by significantly reducing the key operation unit and the display unit of the washing machine, thereby reducing the cost. In addition, since the course channel and the operation channel key can be selected for each course and stroke in the channel type, the washing machine operation becomes convenient.
