The arbitrary stroke selection area 164 includes a "stroke setting button" 164a, a "reservation setting button" 164b, and a "water amount setting button" 164c. The "stroke setting button" 164a is operated by operating this button.
For example, various processes such as washing only, rinsing only, dehydration only, washing and rinsing can be sequentially set. The contents of these settings can be recognized by lighting the display units 164d, 164e, and 164f. Also, the “reservation setting button” 164
In b, a plurality of reservation times can be set by pressing the same button. In this embodiment, the reservations after 9 hours and 6 hours can be sequentially set by pressing this button. Then, the setting content is displayed on the display section 164g as the reservation status. The "water amount setting button" 164c
Sets the amount of water according to the amount of clothing. In this embodiment, three levels of large, medium, and small can be set, and three display sections 164h, 1
64j and 164k are provided. These three indicators are provided as a measure of the amount of detergent.

The operation panel 1 according to this embodiment will now be described.
In 50, each area is sequentially arranged from right to left in accordance with the operation. Then, this array is arranged from right to left, linking to the operation frequency.

For example, in this embodiment, first, the "open button" 161a of the opening / closing lid operation area 161 is set.
By pressing, the operation is started. Therefore, the "open button" 161a is provided on the right side to clarify the operability and the existence of this button. The reason why the "open button" 161a is provided separately from the "on / off button" 162a is that, in many cases, even when the power is off, the opening / closing lid 300 is opened to insert clothes. Thereby, the electric washing machine 1 can be used as an undressing basket.

Next, with the opening / closing cover 300 opened, clothes are put in, and the opening / closing cover 300 is closed again, the power supply area 1 is closed.
Turn on the power with the 62 "ON / OFF button" 162a.
By selecting any one of the three selection buttons 163a, 163b, 163d in the mode washing / start area 163, a typical washing operation can be executed. If the representative washing process is to be changed, the user operates the optional process selection area 164 and then presses any one of the three selection buttons.
Using one of the three basic modes, the selected mode can be partially changed by operating the optional stroke selection area 164 to set another mode of the washing process.

For example, in the standard mode, the washing 12
The washing process is performed for one minute, shower dehydration, one rinse, and seven minutes of dehydration. A combination of the setting of the “stroke setting button” 164a and the operation of the “standard mode button” 163a causes a washing of 14 minutes. １６16 minutes, water injection twice, dehydration 7 minutes 脱水 9
You can select the minute mode.

Similarly, in the dry mode,
By pressing the "dry mode button" 163c with the "water amount setting button" 164c to set the water amount to high or medium, it is possible to select the soft water flow mode in which the washing process is executed with the soft water flow.

As described above, in this embodiment, since the operation buttons are arranged along the operation process from right to left, the operation can be performed without a sense of incongruity, so that the operability can be improved. In addition, since the mode selection function and the start function are shared by the three representative selection buttons that are frequently used, the operation process can be shortened. And
The three selection buttons and the arbitrary stroke selection area 164
By combining the above operations, a plurality of washing modes other than the three washing steps can be selected.
