The washing machine motor 5 is rotated in forward and reverse directions during the washing process and the rinsing process, and is driven by the agitator 4 through the mechanism section 6.
Drive in forward and reverse rotation. Further, the washing machine motor 5 is rotated in one direction during the spin-drying process to rotationally drive the rotating tub 3 via the a48 portion 6. Note that 7 is an electromagnetically driven drain valve.

Next, FIG. 5 shows an operation panel 8 provided on the front upper surface of the washing machine.
The course selection switch 9. Water flow selection switch 10.
Washing time selection switch 11゜Rinse number selection switch 1
2. Dehydration time selection switch 13. Soak washing designation switch 14. Soaking washing unit number setting switch 15. Water level selection switch 16. A start switch 17 is provided. The operation panel 8 is also provided with display lamps 18 to 39 for displaying the contents of the driving course, various selection settings, and whether or not soaking washing is specified. A number display 39a is provided for displaying the number of times.

On the other hand, in FIG. 3, 40 is an electromagnetically driven water supply valve;
1, 42, and 43 are the washing machine motor 5 and the drain valve 7, respectively.
A drive circuit 44 is a microcomputer for turning off electricity to the water supply valve 4o. This microcomputer 44
owns a laundry operation program, and the laundry operation courses executed by the program include "Standard", "Speed", "Large Wash", and "Hand Wash".

This driving course is selectively selected depending on the number of times the course selection switch 9 is operated. The above "Standard" course is suitable for washing when the fabric quality (fabric strength) or degree of dirt is normal, while the "Speed" course is suitable for washing when the fabric quality is normal and the degree of dirt is not too severe. The "large item washing" course is suitable for washing fabrics that are of strong quality or heavily soiled. "Hand washing" is suitable for washing when the fabric is weak or lightly soiled. In addition, the upper microcomputer 44 is capable of performing soaking washing, and in this case, when the soaking washing designation switch 14 is operated, it specifies execution of soaking washing as "yes", and , soaking washing is performed before the washing of the selected course among the above-mentioned operation courses. As shown in FIG. 2, the above-mentioned soaking washing is defined as one unit, for example, 1 minute of stirring (washing motor 5 driven) and 9 minutes of agitation suspension.

Here, the microcomputer 44 individually determines the unit number of soaking washing operation modes for each operating course to be executed, that is, as shown in FIG. 1, for the "standard" course. The number of units is set to "3" for the "Speed" course, "r4J" for the "Large Item Washing" course, and "2" for the "R Hand Washing" course. As you can see from this, "large item washing" is selected when the fabric is of strong quality or is heavily soiled.
The number of credits for the course is as high as r4J, and the number of credits is "3" for the "Standard" course and the "Speed" course, which are selected when the fabric quality is normal or the degree of dirt is normal or slightly light. 1 for "hand washing" when the fabric is weak or lightly soiled.
The number of times he finished in 11th place decreased to 2. Then, when the above-mentioned pickling washing designation switch 14 is operated and the course selection switch 9 is operated, and then the start switch 17 is operated, the number of units (operation mode) corresponding to the selected operation course is set. After soak washing is performed in , the washing operation is performed in the selected course. In this case, when the course selection switch 9 is operated, the set unit number at that time is displayed on the number display 39a. Furthermore, if the course selection switch 9 is operated without operating the pickling washing designation switch 14, the soaking washing is not executed and the washing operation is executed in the selected course.

Note that the number setting switch 15 is used when the user wants to set the unit number of soaking washes according to his/her preference.

According to this embodiment described above, the 11th number of times of soaking and washing is set in association with various driving courses that are selected depending on the quality of the cloth or the degree of dirtiness, and the number of times of soaking and washing is set corresponding to the selected driving course. Since soaking is performed at the 111th number of times, when the fabric is stiff or heavily soiled, there is no need to unnecessarily lengthen the soaking time. If the fabric is extremely dirty, soaking and washing can be carried out sufficiently, and in general, the optimum soaking and washing can be carried out depending on the quality of the fabric or the degree of soiling.

[Effects of the Invention] As is clear from the above description, the present invention allows the washing operation to be performed in one of a plurality of operation courses predetermined according to the fabric quality or dirtiness of the laundry. It is possible to selectively perform soaking washing in which one unit is agitation execution for a predetermined time and agitation suspension for a predetermined time, and select the operation course. and a soaking washing designation switch for specifying execution of soaking washing, wherein the unit number of soaking washing is individually determined for each operation course, and When the soak washing designation switch is operated and the course selection switch is also operated to perform the operation, soak washing is performed for the number of units corresponding to the operating course selected by the course selection switch.
