A control device (also not shown), such as a microcomputer, is disposed inside the device for controlling the execution of operation in response to the operations of the switches 9 to 15 described above.

Therefore, in the case of the above configuration, first operate the course changeover J selection switch 14 and select "manual" based on the light emitting status of the light emitting diode 27, which changes in sequence with each operation, and then "Prewash" selection switch 9
, and select "Contains detergent" based on the light emitting status of the light emitting diode 17, which also changes in sequence with each operation, and then select "Contains detergent" in the same way for the "Detergent" selection switch 10. "Standard", "rlO minutes" for the "Main wash" selection switch 11, "2 times" for the "Rinse" selection switch 12, and "5 minutes" for the "Dehydration" selection switch 12. After setting, if you operate the "start" switch 15, the operation will start from the fourth stage.
The content is shown in the figure. That is, in the first "pre-washing", first "water supply" is carried out with the supply of a set amount of detergent of the standard Qfn, and then "washing" is performed for a predetermined 15 minutes, for example, by rotating an agitator. is carried out, and "drainage" is carried out.In particular, in the case of this embodiment, "water supply"
"drainage" is continued until a water level switch (not shown) is activated, and "drainage" is continued until a drainage sensor (also not shown) is activated.The time for each is variable and varies depending on the conditions at that time, so they are indicated by "・" in the diagram. There is. And after this,
In the "main washing", "water supply" is performed with the same standard amount of detergent as described above, followed by "washing" for 10 minutes according to the settings, and "draining". Furthermore, after this, "dehydration" is performed for a predetermined 2 minutes, then "water supply" is performed without detergent supply, and "rinsing" is performed by rotating the agitator for a predetermined 2 minutes. is carried out, and then "drainage" is carried out. These "dehydration", "water supply", "rinsing", and "draining" courses are performed again according to the "rinsing" setting of 2 times, and then "dehydration" for 5 minutes according to the setting. is performed, and the operation is terminated.

On the other hand, the selection switch 14 for "course switching"
Based on the selection status of "Manual", the selection content with the "Prewash" selection switch 9 is set to "No detergent", the other selections are made as described above, and the "Start" switch 1 is selected.
When step 5 is operated, in the first "pre-wash", "water supply" without detergent supply is performed, and then the pre-determined 1.
"Washing" is performed for 5 minutes, for example, by rotating a stirrer, and "draining" is performed. And then “book washing”
The subsequent steps are carried out in the same manner as described above.

In addition, in the above case, set the selection content using the "hand wash" phase selection switch 9 to "no detergent/no drainage", and then set the other selection content in the same manner as described above, and then press the "start" switch 1.
When you operate step 5, in the first "pre-wash", first wash the detergent.
``Water supply'' without water supply is performed, and then ``washing'' is performed for a predetermined 15 minutes, for example, by rotating an agitator, and ``drainage'' is not performed, and the water remains in the water storage state for subsequent ``washing''. Shift to "main washing". In addition, "main washing" at this time
In "water supply", if there is a shortage of water due to water seeping into the laundry, the water supply to replenish the amount is accompanied by the supply of detergent, and if there is no shortage of water, the water supply is sufficient to supply the detergent. It is done. The rest is the same as above.

In the above, if the selection content with the selection switch 9 for "child wash" is set to "no prewash", "prewash" will be omitted and the operation will start from "main wash", and "detergent wash" will be omitted and operation will start from "main wash". ”
If you select "more" with the detergent selection switch 10, the amount of detergent supplied will be larger, and conversely, if you select "less"
If you do that, it will be less. Furthermore, if the selection content with the "main washing" selection switch 11 is set to "15 minutes", "
The "washing" time in "main washing" is now 15 minutes, and "
5 minutes, it becomes 5 minutes. In addition, “rinse”
If the selection content with the selection switch 12 is set to "3 times," the courses of "dehydration,""watersupply,""rinsing," and "drainage" performed after "main washing" will be performed three times, and "one time." If you do this, it will be done once. In addition, if the selection content by the "dehydration" selection switch 13 is set to "3 minutes", the final "dehydration" time will be 3 minutes, and if it is set to "1 minute", then 1 will become 1 minute.

If the selection content by the "course changeover" selection switch 14 is set to "automatic", the operation will be carried out as a normal course with predetermined symbol-like contents, such as "detergent" in a standard amount and "washing" in a standard amount. 10 minutes, "rinse" twice, "dehydrate" three times
done in minutes.

In addition, on the other hand, the selection switch 14 for "course switching"
If you select "Speed" as the selection content, it will be abbreviated content, for example, "Detergent" should be less, "Wash" should be 5 minutes,
"Rinsing" is performed once, and "dehydration" is performed in 1 minute. 1st
The figure shows the driving details of this - "Speed" course.

In this way, according to this embodiment, the amount of detergent supplied in the "speed" course is changed from the amount of detergent supplied in the "speed" course to the normal course (in the case of this embodiment, "
This reduces the amount of detergent used in the "Speed" course, making it possible to save money and improve economic efficiency.

Note that the specific contents of the "speed" course are not limited to those described above, and can be determined and implemented as appropriate. The same applies to other courses as well.
