The present invention relates to a misoperation display method of a washing machine, and more particularly, to a misoperation display method of a washing machine so that the washing machine can display a misoperation state during a kiosk operation for a desired washing administration.

Recently, as the industrial technology is developed, the washing machine, which is a kind of home appliance which is used in daily life, is also diverse and complicated, so that the user who uses the washing machine does not have a prior knowledge about the use of the washing machine. The washing administration cannot be made smoothly, and in the case of the washing machine, when the user selects the washing administration desired through the key input unit, the washing machine is configured to perform the washing administration selected by a predetermined program by its own microcomputer.

Therefore, when using the washing machine, sometimes the user selects an undesired key input or inadvertent operation due to inadvertent operation, the washing machine proceeds to the washing process with the key input. It should be recognized immediately and canceled. In the case of the washing machine, when the user does not input the key for the washing administration corresponding to the washing administration desired by the user, the user is not able to immediately recognize the convenience of using the washing machine. I have a problem that I can not give.

Therefore, an object of the present invention is convenient for use of the washing machine, so that when the washing machine is not used for the desired washing administration when the key input corresponding to the washing administration is not made, the key selection is displayed incorrectly so that the washing administration or washing stops. To give.

In order to realize the above object, the present invention provides a key signal recognition step for recognizing a key signal input for a washing, rinsing, and dehydrating operation, which is a series of washing operations, and the washing, rinsing, and dehydrating operation in the key signal recognition step. If a key signal for the washing, rinsing, and dehydrating stroke is input in the error display step of displaying an error message when the key signal is not input, and the key signal recognition step, the key signal corresponding to the washing, rinsing, and dehydrating stroke is received. If the stroke corresponding key signal input judging step for judging whether it has been input, and if the stroke key signal is not input in the stroke corresponding key signal input judging step, an error message is displayed; Characterized in that it consists of the steps of proceeding to the washing.

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

FIG. 1 is a schematic control block diagram of a washing machine used in the present invention, and includes a key input unit (A) for inputting an operation signal for a washing, rinsing, and dehydrating process, which is a series of washing operations, and inputs from the key input unit (A). A microcomputer (b) which controls and outputs a signal controlled by a predetermined program with respect to the predetermined signal, and a display unit which displays a key input state by the control signal of the microcomputer (b) and displays a washing process. (C), a motor driving unit for washing, rinsing, and dehydrating driving by the control signal of the microcomputer (b), and a water supply / driving unit for supplying and draining the washing water to the washing tank by the control signal of the microcomputer (b). (E) and an error display section (bar) for displaying an error by the control signal of the microcomputer (b).

2 is a flowchart of a misoperation display method applied to the present invention, in which a washing administration selection step (21) is used to determine whether a washing administration selection signal is input during washing, rinsing, and dehydration, which is a series of washing administrations in an initializing state. And, if the washing administration is not selected in the washing administration selection step 21, if the washing administration is selected, and if the washing administration is selected, the washing administration execution key input for determining whether a key signal relating to the washing administration execution is input; A rinsing stroke selection judging step 23 for judging whether a rinsing stroke has been selected if a key signal relating to the washing stroke execution is input in the determination step 22 and the washing stroke execution key input judging step 22; and the rinsing stroke If the rinsing stroke is not selected in the selection judging step 23, the next stroke is selected. If the rinsing stroke is selected, it is determined whether a key signal relating to the rinsing stroke is input. Dehydration administration selection step of judging whether or not the dehydration administration is selected if the key signal for performing the rinsing stroke in the rinsing stroke execution key input determination step 24 and the rinsing stroke execution key input decision step 24 to determine 25), and if the dehydration administration is not selected in the dehydration administration selection step 25, the washing start signal is selected, and if the dehydration administration is selected, the dehydration administration determines whether a key signal for performing the dehydration administration is input. Each stroke is performed in the execution key input determination step 26, the washing administration execution key input determination step 22, the rinsing stroke execution key input determination step 24, and the dehydration administrative execution key input determination step 26. If a key signal for performance is not input, an error display step 27 for displaying an error message is made.

Referring to the effects of the present invention made as described above are as follows.

First, when a user wants to perform a series of washing administration, when power is applied to the washing machine, the washing machine is initialized, and the microcomputer (b) goes to the washing administration selection judging step 21 by a predetermined program. It is determined whether or not the washing administration selection signal is input from the input unit, and if the washing administration selection signal is not input, the microcomputer (b) maintains the standby state until the washing administration selection signal is input. Subsequently, the standby state is maintained until the washing administration selection signal is input. Then, when the washing administration selection signal is input, the microcomputer (b) controls the display unit (c) to display the washing administration and wash. Go to the administrative execution key input judging step 22, and the key signal regarding the water supply level and washing time for the washing administration execution from the key input unit a. Is input, and if a key signal other than the key signal related to the washing administration is input, the microcomputer (b) goes to the error display step 27 and indicates that the key signal relating to the current washing administration is input incorrectly. The display unit (bar) is controlled to indicate to the user that the operation is immature.

However, if a key signal for washing administration execution is input from the key input unit (a) in the washing administration execution key input determination step 22, the microcomputer (b) goes to the next administration rinsing administration selection determination step 23 It is determined whether the rinsing stroke selection signal has been input from the input unit, and if the rinsing stroke selecting key signal is not input, the microcomputer (b) determines whether the signal for the next stroke, the dehydrating stroke, is input. The dehydration administration selection judging step 25 determines whether the dehydration administration selection key signal has been input. At this time, if the dehydration administration selection key signal is not selected, the process goes to the start of washing.

On the other hand, if the rinse stroke selection key signal is input to the rinsing stroke selection step 23 and the rinsing stroke selection key signal is input from the key input unit a, the microcomputer (b) goes to the rinsing stroke execution input judging step 24 and from the key input unit a. It is determined whether a rinsing stroke key signal for a water level, rinsing frequency, etc., for rinsing stroke performance is input. In this case, if a key signal other than a key signal for rinsing stroke is input from the key input unit, the micom (B In step), the control unit displays the error indication step (27) to control the error display unit (bar) that the key signal related to the current washing administration is incorrectly input and informs the user.

However, when the rinsing stroke key signal is input in the rinsing stroke execution key input judging step 24, the flow proceeds to the dehydrating stroke selection judging step 25, which determines whether a signal for the dehydrating stroke, which is the next stroke, is input. If the dehydration administration selection key signal is not selected at this time, the dehydration administration selection key signal goes to the start of washing. On the other hand, if the dehydration administration selection key signal is input from the key input unit (a), the micom (b) displays the display unit (c). The control panel displays the dehydration administration and goes to the dehydration execution key input determination step 26 to determine whether a key signal regarding the dehydration time for the dehydration administration is input from the key input unit (A). If a key signal other than the key signal for the dehydration operation is input from the key input unit A, the microcomputer (b) goes to the error display step 27 and displays the current three signals. When the key signal related to the stroke is input incorrectly, the user controls the error display unit (bar) and indicates that the operation is immature. On the other hand, when the key signal for the dehydration operation is input from the key input unit, the micom In (b), it is determined that the operation signals for the washing, rinsing, and dehydrating administrations, which are the series of washing operations, are input without misoperation. Then, when a washing start signal is input from the key input unit (a), the microcomputer (b) The water supply and drainage driving part (e) is controlled by an input series of washing administrations to supply water to the water level set in the washing tank, and the motor driving part (la) is controlled to drive the motor while washing, rinsing, and dehydrating.

As described above, in the present invention, when an initial user inputs a key to perform a series of washing operations, washing, rinsing, and dehydration, an error signal is sometimes displayed when a key input for each stroke is misoperated. The user can prevent the washing stop and undesired washing, which may be caused due to inadequate or inexperienced operation, in advance, thereby providing an effect that may provide more convenience to the use of the washing machine.
