[Problem to be Solved by the Invention] In this way, the setting of a driving reservation involves inputting and setting the current time, displaying it, manually setting and displaying the end time of the reserved driving, and then setting the laundry contents. Not only does this require many key switch operations, which is troublesome, but the setting of the reservation time and the setting of the washing contents are performed using different types of switches, and are displayed on different displays. Furthermore, the current time and scheduled time are input and set using separate switches in hours and minutes, making the switch operations complicated and difficult to remember and setting. Errors are likely to occur, and reserved operation may not be executed.

The purpose of the present invention is to solve the above-mentioned disadvantages of the conventional example, and when setting a driving reservation, it is possible to simplify the switch operation, make input settings easy, prevent operational errors, and ensure that the reserved driving is executed. The purpose of the present invention is to provide a display device for a washing machine that can be used.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a fully automatic washing machine that can be operated by reservation using an electronic control circuit such as a microcomputer, in which a plurality of lamps that emit light independently are arranged in series. The gist is that the time until the reserved operation ends and the washing details such as wash time, number of rinses, spin-drying time, etc. are displayed in common by lighting one of the plurality of lamps corresponding to the setting contents. It is something to do.

[Effect]

According to the present invention, when setting a driving reservation, especially setting the reservation time, it is only necessary to input and set the time from the current time to the end of the driving and turn on the lamp corresponding to the setting contents, so one switch is sufficient. Setting operations are easy and there is no risk of making mistakes.

In addition, the time until the end of the reserved operation is displayed using the same display lamp that displays the laundry contents, so the display can be unified and the number of displays can be reduced. Since it can be input and displayed in the same way as the display, it is easy to see and operate.

〔Example〕

The following is a front view of an operation panel showing an embodiment of the display method of a washing machine according to the present invention, and the overall configuration of the washing machine is shown in a second view.
Since it is the same as that already explained with respect to the figure, detailed explanation here will be omitted.

The display device of the present invention is also provided with an operation panel (5) on the top of the outer box (1), and this operation panel (5) has various push-type switches and indicator lamps exposed on the surface. did.

The switches include a process setting switch (9) that sets the washing time, number of rinses, and spin-drying time as part of the washing process;
A water level switch (10) for setting the water level to be used, a fully automatic course switch (11) for selecting the desired one from preset courses such as standard and speedy;
A reservation switch (13) for setting the reservation operation and setting the time from the current time to the end time of the reservation operation, a start/stop switch (38), and an on switch (14a) and an off switch (14b) as a power switch (l4). ),
Among these, the process setting switch (9) and the fully automatic course switch (11) were arranged in a row in the horizontal direction.

As indicator lamps, a plurality of (14 in the illustrated example) indicator lamps (7) using LED (light emitting diode) lamps are placed above the process setting switch (9) and the fully automatic course switch (11). These 14 display lamps (7) are used to display the time from the current time to the scheduled operation end time in hourly increments, and the time is displayed above the display lamps (7). '15J' is written below the display lamp (7) as a lamp to indicate the settings and course of washing time, number of rinses, dehydration time, and the course.
'IIJ r7'r3'' washing time number, r2
, r1'' times, numbers and letters indicating the number of rinses for ``Water injection'' and the water rinsing, numbers for r5, r3, rlJ dehydration times, and letters indicating the course of ``Standard'', ``Speed'', ``Careful'', and ``Delicate''. I wrote each.

Further, above the water level switch (10), letters and lamps (39) are provided to indicate the water level used, ``high'', ``medium'', and ``low'', separately from the indicator lamp (7).

Next, to explain how to reserve a run, first, as a setting when the reserved run ends, specify how many hours from now you want the washing run to end, and set the time from the current time until the end of the reserved run in units of hours. Set the input with . For example, each time you press the reservation switch (13), the display lamp (7)
The lights will skip one by one from hour ``l'' to hour ``14,'' so if you want to start driving at a desired time, for example 10 hours from now, press rl.
When the display lamp (7) located below the OJ number lights up, the operation of the reservation switch (13) is stopped.

Next, set the washing contents such as washing time, number of rinses,
The dehydration time is determined using the process setting switch (9). At this time, the "
The indicator lamp (7) at the position indicating the 10'' time goes out, and only the indicator lamp (7) at the position corresponding to the set washing time, number of rinses, and dehydration time is lit.

Furthermore, after setting the water level to be used with the water level switch (10), if you press the start/stop switch (38),
Timing is started so that the operation will end after 10 hours.

During this period, until the reserved operation starts, the display lamp (7) lights up in skip mode to display the remaining time until the end, and after the start time arrives and the operation starts, the set washing, rinsing, and spin-drying steps are displayed.

〔Effect of the invention〕

As described above, the display method of the washing machine of the present invention is such that when setting a reservation for operation, all you have to do is enter only the number of hours from now when you want the operation to end. Moreover, since all you have to do is turn on the lamp corresponding to the desired time, the input operation is simple, human error can be prevented, and reserved operation can be executed reliably.

In addition, this display lamp is also used to display the set washing contents, so not only can the number of lamps be reduced, but also the setting of reservation time and washing contents can be done with the same input operation. It is easy to input and operate.
