Next, the operation will be described. When the washing machine is not used, the current time is displayed on the numeral display section as shown in FIG. When washing is performed, the operation switch 17 is pressed to set a fully automatic course, washing contents such as washing time, water level, water flow intensity, and the like. FIG. 13 shows the state of the display unit 18 in a state where such settings are made. In the example shown in the figure, the standard course is set, washing 14 minutes, rinsing 2 times, dehydration 5
Minutes, water level is high, and water flow is standard.

At this time, as shown in the process diagram of FIG. 12, the storage device 20 stores the process of carrying out the set washing content. In this case, "1" indicates a step to be carried out, and "0" indicates a step not to be carried out.

The laundry content is set in this way, and when the start switch is turned on, the laundry is automatically advanced by the output from the control device 5 according to the set laundry content. By the way, while washing is in progress, the operation may be stopped halfway due to a failure or an operation error. In such a case, conventionally, a user is informed of an abnormal operation by a buzzer or the like.

[0009]

When an abnormal operation is notified, the user usually turns off the power to ensure safety. However, when the power is turned off or a power failure occurs, the washing set in the storage device is performed. All content information is lost. Therefore, after that, when the service person inspects, there is no clue to find out the failure point such as in which process the failure occurred and the cause of the failure, and it is necessary to check all operations during the washing process. It takes time.

Further, since the location where the inconvenience has occurred is not specified, if the occurrence of the inconvenience is not reproduced at the time of inspection, it will be a prospective repair, and the accuracy of the repair is low.

The object of the present invention is to eliminate the inconvenience of the conventional example, and in the case where the washing process is stopped midway due to a failure or the like, the contents of the accident and the remaining process are memorized, and the result is checked by a serviceman. An object of the present invention is to provide a method of storing and displaying an abnormal operation of a washing machine, which can be displayed and used as a clue for repair, and workability and accuracy of repair can be improved.

[0012]

In order to achieve the above-mentioned object, the present invention is a fully automatic washing machine in which a washing process is automatically performed by an output from a control device. When stopped, a memory circuit is provided so that the memory will not be lost even if the power is turned off. The remaining steps and accident details that have not been executed are stored in the memory circuit, and when the accident determination mode is set, the laundry content is normally displayed. The remaining process and the accident content stored in the storage circuit are displayed by turning on the lamp.The accident determination mode uses the individual display lamps for setting the laundry content as the display information of the washing process and the accident content in advance. The point is to set the lighting point according to the above, and to switch to the accident determination mode when the switch for setting the laundry content is turned on in a usage method that is not used in normal laundry operation. A.

[0013]

According to the present invention as set forth in claim 1, even if the washing process is stopped midway due to a failure, an operation mistake, or the like, the remaining process and the content of the accident are stored in the memory circuit, and when the accident determination mode is set, Since the remaining process and the contents of the accident stored in the storage circuit are displayed by turning on the display lamp for setting the contents of washing, it is easy to understand the failure point and the cause at the time of inspection by a service person.

According to the second aspect of the present invention, the accident determination mode can be set by turning on the switch for setting the laundry content by a method not used in normal washing operation.
Further, since the contents of the accident and the like are displayed on the display lamp which is usually used for setting the contents of washing, existing parts can be used, and the structure is not particularly complicated.

[0015]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a flow chart showing a storage operation of a washing machine operation abnormality storage and a display method of the present invention, and FIG. 2 is a flow chart showing a display operation of the same. The overall configuration of a washing machine in which the method of the present invention is carried out is shown in FIG. 8 and FIG. 9 is the same as that already described, and the configuration of the key input unit 2 is also the same as that already described with reference to FIG. 10, so a detailed description thereof will be omitted here.

In the present invention, the storage device 20 shown in FIG.
Is configured such that the stored contents are not lost even when the power is turned off, and the washing contents set by the operation switch 17 at the start of washing, for example, the washing contents shown in FIG. 12 are stored.

Further, the display section 18 of the key input section 2 shown in FIG. 4 is used as a display section of the remaining process when the accident determination mode is set. In this case, the washing content is displayed corresponding to each of the seven subdivided steps of the washing step “0”, the rinsing step “1” and “2”, and the dehydration step “3” shown in FIG. 12. The lighting location of the lamp 19 is set in advance.

FIG. 5 shows a correspondence table between the steps and the lamps 19,
For example, a display lamp 19 for "dehydration" at positions "0" and "0"
Indicates the first "washing" step in the washing step "0",
The “D ₂ ” indicator lamp 19 at the “2” and “3” positions indicates the “3” -th “fast dehydration” step in the rinsing step “2”.

When the accident determination mode is set, the display section 18 of the key input section 2 is used as the display section for the accident content, and the water level and water flow display lamps 19 shown in FIG. Set the lighting points according to the content of the accident.

Next, the operation will be described with reference to the flowchart of FIG. At the start of washing, the operation switch 17 is used, for example, as shown in FIG.
When the laundry content as shown in 2 is set, this is stored in the storage device 20. Then, when the washing operation is started and the operation is stopped halfway when the process reaches the "drainage 7" step of the "rinsing step 1" shown in FIG. 3 [step (a) (b)], it is stored as an abnormal operation. "Defective drainage" is stored in the device 20 as the content of the accident [step (c)], and the setting process of FIG. 12 and the "rinsing process 2" of FIG.
The remaining processes thereafter are stored [step (d)].

Thus, when the washing operation is stopped on the way,
Even if the power is turned off thereafter, the accident content information and the setting process and remaining process information stored in the storage device 20 are not lost.

Then, when the service person carries out the inspection thereafter, the operation switch 17 is not used in the usual setting of the washing content, for example, the washing switch and the rinsing switch are simultaneously pressed [step (e)], Further, if the time switch is pressed to set the accident determination mode [step (f)], the remaining process, the content of the accident and the set course are displayed on the display unit 18 as shown in FIG. 7 [step (g)]. .

Therefore, looking at the display of the display unit 18,
In the example shown in the figure, from the lighting position of the lamp 19 that normally displays a number, from the correspondence table of FIG. 5, that the “rinsing process 2” and thereafter are not in operation, and the water level display lamp 19 lights at the “middle” position. It is found that the content of the accident is “drainage failure” and that the course selected from the lighting of the lamp 19 at the “sensor” is the “sensor (standard) course”.

Further, if the minute switch of the operation switch 17 is pressed [step (h)], the course, the washing time, the number of rinses, the dehydration time, the strength of the water flow, and the water level shown in FIG. The washing setting contents at the time of the accident such as is displayed again [step (re)]. As a result, it becomes clear what kind of process was set, at what stage the process was stopped, what the accident was, and the service person can easily find out the location of the failure and the cause of the failure.

As a method of not using the operation switch 17 in the normal setting, in the above-mentioned embodiment, the washing switch and the rinsing switch are simultaneously pressed, and further the time switch is pressed, but the present invention is not limited to this. It is also possible to use other operation switches. In addition, if it is pressed in the normal usage manner, normal operation is started [step (nu)].

[0026]

As described above, the method of storing and displaying the operation abnormality of the washing machine according to the present invention is a fully automatic washing machine in which the washing process is automatically performed by the output from the controller, and the washing is performed due to a failure or the like. When the process is stopped in the middle of the process, the content of the accident and the remaining process can be stored and displayed during inspection by a service person to be used as a clue for repair, thereby improving workability and accuracy of the repair.

Since the contents of the accident and the like are displayed by using the display lamp for setting the contents of washing, the number of parts does not particularly increase and the structure does not become complicated.
