The operation of this embodiment will be explained according to flowchart -1 in Fig. (5). When the power switch (22) is turned on, the microcomputer (23) starts operating, resets the output terminal of the microcomputer, and then clears the internal data write memory (RAM) to be in an initial state.

When any of the pre-course selection start switches (28) to (33) is input, a course corresponding to this input is set. If any of the course selection and start switches (28) to (33) cannot be input again within 3 seconds after that, driving on the fully set course is started, and then the start switches 28) to (33) are input. No input will be accepted and course changes will not be possible. If any of the other start switches (28) to (33) is input within 3 seconds, a course based on this new start switch is set. If the same start switch (28) to (33) is pressed twice within 3 seconds, a careful course is selected, and the washing process time, rinsing process time, and spin-drying process time are set longer. Further, when the reuse switch 34> is set to the (water tank) drain position and any of the start switches (28) to (33) is pressed, the (water tank) drain course can be set.

゛ First, the (water tank) drainage course, which is a feature of the present invention, will be explained. This drainage course is connected to the connecting valve (17)
and the drain valve (10) is opened, and the top! (42) is opened and the lid switch 41 is open and the liquid level switch (41) is open.

6) Supply water from. If you connect an external hose to the water supply 1 (36), this hose will open the water tank <15>.
Water can be introduced to the side to easily wash the water tank (15). Since the connection valve (17) and the drain valve (lO) are open, the water introduced to the water storage tank (15) can be immediately introduced into the IJ. Of course, the interior of the washing tub (3) can also be easily cleaned using this bowl.

Here, the liquid level switch (25) is opened 1. The water supply valve (35) is opened only when the water is in the $Llv tank (3).
This is for safety reasons, as there is liquid in the tank and if water is supplied from the water supply 1-1 (36) if the drain hose is forgotten to be turned down, the water may overflow.

Also, if you close the top lid (42) and close the lid switch (41), the water supply valve (35) will not open, so the water tank (15) will not open.
Only the ash tank (3) and the ash tank (3) can be drained at the same time.

The connecting valve (17) and the drain valve (1o) are closed after 3 minutes, and the buzzer (43) is sounded to notify the end of the drain course (water tank).

The push-washing course is a special washing course used for washing soft items such as sweaters and blankets, and its explanation will be omitted here.

For normal washing cycles, select the course and start switch (
28> to 32> and the reuse selector switch (34), each course is operated as shown in the stroke diagram of FIG. 4.Detailed explanation thereof will be omitted here.

In addition, the "tank cleaning process" shown in Figure 4 means that the connecting valve (1
7), and 10 seconds later, rotate the pump (18) in the forward direction, open the drain valve (10), and turn the liquid level switch <25
) is opened, only the pump (18) is stopped. This operation causes the water tank (15>
The water that has moved inside is stirred to remove dirt adhering to the walls of the water tank, and this dirt is discharged via the connecting valve (17) and drainage water 110).

(F) Effects of the Invention The washing machine with a water storage tank of the present invention has a valve device for draining the liquid in the washing tank, a valve device for draining the liquid in the water tank, a water supply valve, and a water supply valve. It supplies water into the washing tub and has a water supply port to which an external hose can be connected, and both valve devices for drainage are opened for a predetermined period of time, and the top lid on the washing tub side is opened. Since we set a drain course (water tank) immediately after the process of opening the water supply valve for a predetermined time as a condition, by performing the above process with the top cover open and the external port connected to the water supply port, the external port can be drained. You can wash the water tank by directing water to the water tank at the washing machine, or you can wash the washing tank without disconnecting the water supply hose from the washing machine or introducing water from another tap far away. It can be easily cleaned at any time.

Also, if you close the top lid and perform the above process, you can drain only the washing tub and water tank at the same time, which simplifies the t-P water operation and creates a separate process for draining only. .
