2. Description of the Related Art In a laundry machine of this type, for example, a fully automatic washing machine, a self-diagnosis program as shown in the flowchart of FIG. 6 is started at the time of or after assembling a product to check the product. . Specifically, after the power is turned on (proceeding to “YES” in step S1), a special operation is performed on the operation switches on the operation panel, for example, by pressing two predetermined operation switches at the same time, various sensors can be operated. Set the mode for judging the value (A / D value) of the input data given to the operation control device (proceed to “YES” in step S2), and display the value of the input data on the display of the operation panel (step S3) .

In this case, by appropriately operating the operation switches, the values of the input data corresponding to the various sensors are displayed on the respective display devices to check the various input data.

After the power is turned off (step S4: YES), the power is turned on again (step S1: YES), and a special operation with different operation switches is performed. By doing so, the mode is set to determine the auto power off (“YES” in step S5).
Go to). Then, when a predetermined operation switch is operated, an auto power off signal is output and the power is automatically turned off (steps S6 and S7). As a result, the auto power off function is checked.

Further, for the checks other than the above-mentioned functions, after the power is turned on again (proceeding to "YES" in step S1), in the normal operation mode (steps S2, S).
5), proceed to "NO" respectively, and by operating the operation keys as appropriate, the display light emitting diodes are sequentially turned on, and the drive signals for driving the load such as the motor are sequentially output (step S8) to check. I am trying to do it.

[0006]

However, in the above conventional configuration, in order to check all the input / output functions of the operation control device, an operation of setting each of the three check modes (specifically, an operation of turning on the power source) is performed. With 3 times,
It is necessary to perform a special operation with different operation keys twice), which is a troublesome setting work. Therefore, it takes a long time to check the products on the manufacturing line, resulting in poor productivity. Also, when the service person checks the product at the user's house, the check workability is poor.

Therefore, it is an object of the present invention to simplify the operation of setting the check mode when checking all the input / output functions of the operation control device and improve the workability for the check. To provide.

A power switch 8 is provided between the power plug 2 and the drive circuit 7. The power switch 8 can be manually turned on / off and has a solenoid (not shown) built therein. The power switch 8 drives the drive circuit 7 when the auto power off signal Soff is output from the output terminal OFF of the operation control device 1.
When the switching element for the solenoid provided inside is turned on and the solenoid is driven, it is automatically turned off.

On the other hand, the operation control device 1 receives various switch signals from the input circuit 9. The input circuit 9 has seven key switches 10a to 10g which are turned on and off by operating a plurality of, for example, seven operation keys (not shown) provided on an operation panel (not shown).
(See FIG. 5) and a door switch 11 (see FIG. 5) that is turned on and off by opening and closing a door (not shown) that opens and closes the clothes entrance and exit, and the operation control device 1 outputs switch signals from these switches. Give to.

Further, the operation control device 1 is a four-digit numerical indicator comprising a plurality of, for example, eight display light emitting diodes 12a to 12h (see FIG. 4) and a seven segment type light emitting diode provided on the operation panel. By supplying a drive signal to the display circuit 14 including 13 (see FIG. 5), the display light-emitting diodes 12a to 12h are controlled to be turned on and the display content of the display 13 is controlled. . Then, the operation control device 1 drives and controls the buzzer 16 (see FIG. 5) by giving a drive signal to the buzzer notification circuit 15.

Further, the operation control device 1 includes a sensor circuit 17
The sensor signal (A / D input) output from is input. Specifically, the sensor circuit 17 includes, for example, three sensors, that is, a water level sensor, a capacity sensor that detects the capacity of the laundry, and an optical sensor that detects the degree of dirt of the washing water. The output sensor signals Se1 to Se3 are input to the input terminal A / D1 of the operation control device 1.
~ Give to A / D3. Then, the operation control device 1 inputs the sensor signals Se1 to Se3 as input data.

Next, the operation of the above structure will be described with reference to FIGS. 1, 2, 4 and 5. The flowcharts of FIGS. 1 and 2 schematically show the control contents of the check program stored in the operation control device 1. Further, in the manufacturing line, when checking all the input / output functions of the operation control device 1 during the assembly of the product, instead of the motor 4, the water supply valve 5 and the drain valve 6, an inspection lamp device (not shown) is used as a pseudo load. ) Is connected, and an inspection sensor signal generator (not shown) is connected as a pseudo sensor instead of the sensor circuit 17.

In the above-mentioned connected state, the checker
As shown in FIG. 1, after the power switch 8 is turned on (proceeding to "YES" in step A1), the operation keys are specially operated, in this case, for example, three operation keys are simultaneously pressed ( That is, the three key switches 10a to 10c are simultaneously turned on), the check mode is set, and the check program is activated (proceeding to "YES" in step A2). As a result, the checking of all input / output functions of the operation control device 1 is executed (step A3).

Here, specifically, the check is performed by the control shown in FIG. That is, when the check program is activated by pressing the three operation keys simultaneously, the door is closed and no operation key (key switch) is pressed, so that the steps B1 and B2 are performed. Each proceeds to "NO".

As shown in FIG. 4, the operation control device 1 sequentially turns on the eight display light-emitting diodes 12a to 12h for each predetermined first set time t1, and
The drive signals Sa1 to Sa4 (AC output) for individually driving the loads are sequentially output for each second set time t2 set in advance (step B3). By sequentially outputting the drive signals Sa1 to Sa4, the lamps of the inspection lamp device are sequentially turned on.

In this case, each display light emitting diode 12a
Each of the light emitting diodes 12a is sequentially turned on for 12 to 12h.
It can be confirmed that the control signal for controlling lighting of ~ 12h is normally output, and that each of the light emitting diodes 12a to 12h is normally emitting light. Then, the drive signals Sa1 to Sa4 are normally output by sequentially lighting each lamp of the inspection lamp device, and
It can be confirmed that the drive circuit 7 is operating normally.

Further, the display light emitting diode 12 described above is used.
a to 12h are sequentially turned on and the drive signal Sa1
If one of the eight operation keys is pressed while the output of ~ Sa4 is sequentially output, the process proceeds to "YES" in step B2 to drive the buzzer 16 to drive, for example, 0.1
Sounds for a second and displays the value of the input data corresponding to the operated operation key from the plurality of input data, in this case three input data, on the display 13 (step B
4).

Specifically, as shown in FIG. 5, when the operation key corresponding to the key switch 10a is pressed, the input data input to the input terminal A / D1 is changed only during the pressing operation. The value is displayed on the display 13. When the operation key corresponding to the key switch 10b is pressed, the value of the input data input to the input terminal A / D2 is displayed on the display device 13 only while the operation key is pressed. Furthermore, when the operation key corresponding to the key switch 10c is pressed, the input terminal A / D
The value of the input data input to 3 is displayed on the display unit 13.

In the same manner, the key switch 10d
When the operation key corresponding to 10f is pressed, the input terminals A / D1 to
The value of the input data input to / D3 is displayed on the display unit 13. In this case, the value of the input data input to the input terminals A / D1 to A / D3 is the time T as shown in FIG.
It changes at 1, T2, and T3. Further, when the operation key corresponding to the key switch 10h is pressed, the value of the input data input to the input terminal A / D1 is displayed on the display 13 only while the operation key is pressed.

Further, as described above, when the operation key is pressed, the display light emitting diode 12a is interrupted by the program only during the pressing operation, for example.
~ 12h sequential lighting operation and drive signals Sa1 to Sa4
The sequential output operation of is controlled so as to be temporarily stopped (step B5).

By operating each of the above-mentioned operation keys, displaying the input data corresponding to the operation key on the display 13, and sounding the buzzer 16, each operation key operates normally. It can be confirmed that the operation control device 1 is normally inputting each input data (A / D input), and that the buzzer 16 is sounding normally.

In addition, when one of the plurality of operation keys is pressed, the sequential lighting operation of the display light emitting diodes 12a to 12h is temporarily stopped only during the pressing operation. By visually recognizing the lit display light-emitting diodes 12a to 12h when the display is temporarily stopped, it is possible to reliably check the luminescence state of the lit display light-emitting diodes 12a to 12h such as the luminescence amount and the luminescence variation. It can be carried out.

In this case, by appropriately changing the operation timing of the operation keys, the display light emitting diodes 12a to 12h to be temporarily stopped in the lighted state are changed, so that
The light emitting states of all the display light emitting diodes 12a to 12h can be checked.

After that, in order to check the remaining check item, that is, the automatic power-off function, the door for opening and closing the clothes entrance is opened. As a result, in step B1, the process proceeds to "YES", and the operation control device 1 outputs the auto power off signal (step B6). As a result, the power switch 8 is automatically turned off, and step A4 in FIG.
Then, proceed to “YES” to end the check program.

In this case, the power switch 8 is automatically turned off in response to the opening operation of the door, so that the auto power off signal is normally output from the operation control device 1, and the power switch 8 is turned on. It can be confirmed that the off operation is normally performed.

On the other hand, if the operation key is not specially operated after the power switch 8 is turned on, the normal operation mode is entered (NO in step A2), and normal washing and washing are performed until the power is turned off. The dehydration operation is appropriately executed (steps A5 and A6).

According to the present embodiment having such a configuration, the check program is started by simply operating the operation key after turning on the power switch 8, and all the input / output functions of the operation control device 1 are checked. To be done. For this reason, it is possible to check all the functions with a single special operation of the operation keys. Therefore, compared to the conventional configuration, the work of setting the check mode is simpler, and the check work can be performed on the manufacturing line. The time required can be shortened and the productivity can be improved. Also, when the service person checks the product at the user's house, the check workability is similarly improved.

In the above embodiment, the value of the input data input to the input terminals A / D1 to A / D3 of the operation control device 1 is displayed on the four-digit numerical indicator 13. The present invention is not limited to this, and it is also possible to adopt a configuration in which a one-digit numerical value (hexadecimal number) of the input data value is displayed in binary number using four display light-emitting diodes. Further, in the above embodiment, the display light emitting diodes 12a to 12h are provided only while one of the plurality of operation keys is being pressed.
The sequential lighting operation was controlled to be in the primary stop state, but the invention is not limited to this, and the sequential lighting operation is performed for a predetermined time (for example, several seconds) from the time when one of the operation keys is operated. You may control so that it may be in a temporary stop state. Further, in the above embodiment, the present invention is applied to the fully automatic washing machine, but it goes without saying that it may be applied to a dryer instead.
