(shown as ranges A', B', and C' in FIG. 3).

Reference numeral 29 denotes a selection switch attached to the panel portion 15 of the operation box 11, and is connected to the energizing path 27 in series with the make-up water switch 28. The timer 14 is configured such that when the knob 16 is set to each "wash" position on the timer stroke scale shown in FIG. 6, the timer automatically advances clockwise until "off" and each stroke is performed in sequence. . 30 is a drain valve, and 61 is a dewatering lid switch. Reference numeral 32 denotes a pre-finishing stop switch, and the switch 20 switches the contact pieces (a-b) to open and close at the time when the ``rinsing'' process before the ``finishing'' process is completed. Furthermore, as is well known, the timer 14 has a "standard course" and a "saving course".
You can choose between a ``wash'' only course or a ``wash'' only course.

Next, the operation of the above configuration will be explained. For example, put the rated capacity of laundry into the washing tank 4, set the water level switch 12 to the high water level, and set the knob 16 of the timer 14 to, for example, the "standard course".
When set to the "wash" starting point, water supply will start.

That is, the water supply valve 13 is energized through the contacts (a and b) of the water level switch 12, and the water supply valve 13 is opened to supply water into the washing tank 4. When water is stored in the washing tank 4 and reaches the set water level, the water level switch 12 is activated and the contact pieces (a-c) are closed.
The water supply valve 13 is closed and the water supply is stopped. Thereafter, the motor 7 and the timer motor 25 are energized and a washing operation is performed. Next, a well-known rinsing process is performed in which the drain valve 17 is opened and the water in the water receiving tank 3 is drained, and then new water is supplied and the pulsator 5 is driven by the motor 7. A well-known dehydration process is carried out in which the spindle is rotated.

By the way, there are cases where bulky laundry is washed or laundry whose capacity slightly exceeds the rated capacity is washed. In this case, first, manually close the selection switch 29, set the water level switch 12 to the high water level, and set the knob 16 of the timer 14 to "wash".

Then, water supply is started and water is supplied to the washing tank 4, and as described above, when the water is stored in the washing tank 4 to the set water level, the water level switch 12 is activated and the water supply is stopped, and the motor 7 and the timer motor are activated. 25 is energized and a washing operation is performed. When the timer motor 25 is driven and a predetermined period of time has elapsed, the make-up water switch 28 is closed, so the water supply valve 13 bypasses the water level switch 12 and is re-opened via the supplementary water switch 28'FV and the selection switch 29. When energized, it opens and washes hands.
Replenish and water into h4. Then, after a predetermined period of time has elapsed, the makeup water switch 28 opens, so the water supply valve 13 is turned off.
The water supply will be stopped. As a result, the water level is raised higher than the initially set water level by an amount corresponding to the amount of water replenished, and washing is performed at this higher water level.

According to the embodiment described above, by closing the selection switch 29, the water stored in the washing tank 4 is increased at a predetermined time and the washing process can be performed at a water level higher than the set water level. Even if you have a large amount of laundry to wash, or if the laundry load is slightly more than your laundry capacity, you can wash it in 10 minutes.

Regarding supplementary water, it is carried out in the same manner as described above for both the "saving course" and the "washing only course".

4 and 5 show different embodiments of the present invention, and the difference from the above embodiment is that the selection switch 29
is operated by the operation shaft 62 of the water level switch 12. That is, in FIG. 4, 3"3 is a cam attached to the operating shaft 32, which is provided with a plurality of recesses 33a for setting the water level of the washing tank 4 in multiple stages. 3.
4 is an arm portion formed integrally with the cam 33, and is connected to the operating shaft 32.
As shown in FIG.
If you match the "capacity addition" displayed in 5, arm part 3
4 is adapted to press the liquor selection switch 29 to close it. With this configuration, the user-friendliness of the water level switch 12 is greatly improved because the knob 35 originally used to set the water level can be used to set the water level switch 12 to the down position where water is supplied above the set water level.

〔Effect of the invention〕

As is clear from the above description, in the present invention, a make-up water switch and a selection switch are provided in series in the energization path provided bypassing the water level switch, so that when washing more than the rated capacity of laundry, the water level switch By making it possible to supply water above the set water level to the washing tank regardless of the operation of
