  5A and 5B, after pressing the power button 61 of the terminal operation unit 30 of the terminal device 28, the net course setting unit 31 presses the switching buttons 35a, 35b, and 35c of the terminal input unit 35. Thus, the washing time of the net course, the number of times of rinsing, and the dehydration time can be set, and the set contents can be confirmed on the terminal display unit 34. Then, by pressing the transfer start button 32, the setting contents can be transmitted to the washing machine 29. The transfer start button 32 will be described later with reference to the operation flowchart of FIG. Note that the terminal device 28 can also operate by having a dedicated application as a function of the mobile phone.

  About the washing machine control system comprised as mentioned above, the operation | movement and an effect | action are demonstrated. FIG. 6 is an operation flowchart of the washing machine control system in the embodiment of the present invention. In FIG. 6, when the power button 61 provided on the terminal operation unit 30 of the terminal device 28 is pressed, the net course setting content is provided in the net course setting unit 31 as shown in FIG. It is displayed on the terminal display unit 34.

  Next, in step 42, it is determined which of the washing time, the number of times of rinsing, and the dehydration time is changed from the initial value of the net course setting content. Step 43 shows a case where the washing time is changed. In the example shown in FIG. 5B, when the user touches the touch panel as the terminal input unit 35, the initial washing time “6 minutes” shown in FIG. 5A is changed to the washing time “9 minutes”. An example is shown.

  Step 44 shows a case where the number of times of rinsing is changed. In the example shown in FIG. 5B, when the user touches the touch panel that is the terminal input unit 35, the initial number of times of rinsing “for once” shown in FIG. 5A is changed to the number of times of rinsing “for twice”. The example changed to is shown. Step 45 shows a case where the dehydration time is changed. In the example shown in FIG. 5B, when the user touches the touch panel as the terminal input unit 35, the initial dehydration time “3 minutes” shown in FIG. 5A is changed to the dehydration time “7 minutes”. An example is shown. At this time, as in step 46, the washing machine 29 is turned off. Since the power is off, the washing machine 29 is not ready to receive (receivable state). Therefore, as shown in FIG. 5A, the transfer start button 32 is not displayed.

Next, in step 47, the washing machine 29 is turned on by pressing the power-on switch 26f of the washing machine 29.

  Next, when the user presses the transfer start button 32 in step 51, in the case of NFC, the terminal device 28 is moved closer to the washing machine transmission / reception unit 38 (step 52), so that the terminal transmission / reception is performed in step 53. All data of the net course setting is transmitted from the unit 33 to the washing machine 29. In step 54, the washing machine 29 receives all data of the net course setting by the washing machine transmission / reception unit 38. Next, in step 55, all the received data of the net course setting is stored in the storage unit 40, and in step 56, the net course display unit 27f of the operation display unit 37 is turned on. Since the storage unit 40 is non-volatile, all data can be stored even when the power of the washing machine 29 is shut off.

  Next, in step 57, by pressing the start / pause switch 26e, the washing machine 29 operates a sequence based on the received net course setting content. Note that the washing machine 29 can also drive the sequence by pressing the start button 62 provided on the terminal operation unit 30 of the terminal device 28.
