The life rhythm of the user is almost fixed, and the time for finishing the washing is almost the same every time. Nevertheless, in the conventional reservation method, every time the reservation operation is set, the user calculates the time from the current time to the time at which the user wants to end the washing,
Further, this time must be entered each time, which is troublesome and inconvenient.

An object of the present invention is to solve the above-mentioned disadvantages of the prior art, and the reservation time can be automatically set so that the operation is completed at the same time as the previous time simply by pressing the reservation switch. It is an object of the present invention to provide a operable reservation operation method of a washing machine which eliminates the trouble of calculating and setting inputs.

[0012]

SUMMARY OF THE INVENTION In order to attain the above object, the present invention firstly provides a washing machine reservation driving method for displaying a time from a current time to a time at which the operation is to be terminated as a reservation driving time. After the driving time is set once, when the next reserved driving time is set, the reserved driving time is automatically displayed so that the reserved driving ends at the same time as the previous time, so if the driving end time is the same as the previous time, The reservation driving time is automatically set, and the user does not need to calculate this time by himself, which is convenient.

Second, the reservation operation time is displayed by pressing the reservation switch to calculate and display the time from the current time to the same operation end time as the previous operation by the control device. At the same time, other operations are unnecessary only by pressing the reservation switch.

The reserved operation time displayed third can be changed by the change switch, so that it is possible to cope with a case where the time to be ended is changed, and it is sufficient to operate only in this case, so that the operability is good.

[0015]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a flowchart of an operation showing an embodiment of a reservation driving method of a washing machine of the present invention, and FIG.
Is a plan view of the operation unit of the washing machine in which the method of the present invention is performed,
Since the entire configuration of the washing machine is as described above with reference to FIG. 3, a detailed description is omitted here.

The operation unit in which the method of the present invention is implemented is provided with a reservation switch 21, an increase switch 22, and a decrease switch 23 as input keys for setting a reservation, and as a setting display of the reservation operation, a time display by a segment such as an LED lamp. LE with display section 24 and the word "reserved" indicating that the reservation is being made
A display unit 25b such as a D lamp and a display unit 25a such as an LED lamp provided with characters such as "after time" are provided.

In the figure, reference numeral 26 denotes an automatic switch when the automatic operation is selected, and reference numeral 27 denotes a selection switch when the user arbitrarily sets the washing contents.

The control unit 9 is provided with a storage unit for the operation end time when the reserved operation is performed, and when the reservation switch 21 receives an input, the current time is stored in the storage unit from the current time. An arithmetic circuit for calculating the time until the operation end time at the time of the reserved operation is provided.

Next, the operation will be described with reference to the flowchart of FIG. When the reservation switch 21 is pressed to perform the reservation operation [step (f)], the arithmetic circuit of the control device 9 calculates the time from the current time to the end time of the previous reservation operation time stored in the storage unit [ Step (g)], the calculated reserved driving time is displayed on the display unit 24, and the character "after time" is lit on the display unit 25a (step (h)).

If the user looks at the numbers displayed on the display unit 24 and decides that the same operation end time as the last time is required (step (i)), the user further presses the selection switch 27 as needed to press the water level, the washing time, and the rinsing. The washing contents such as the number of times and the dehydration time are arbitrarily set [step (nu)], and when the start switch 20 is pressed [step (lu)], the display part 25b of the character of the reservation lights up and the reservation operation starts.

When the user does not need to set the washing content and can use the "standard" automatic course, he only has to press the start switch 20.

On the other hand, the user looks at the reserved operation time displayed on the display unit 24 at the stage of [Step (i)], and wants to change the reserved operation time this time by setting the operation end time to be different from the last time. In this case, the increase switch 22 or the decrease switch 23 is pressed to change the currently displayed reserved operation time in units of one hour (step (W)).

As described above, just by pressing the reservation switch 21, the reservation operation time is calculated based on the previous operation end time and displayed. Therefore, even if the current time for setting the reserved operation is different from the previous time, if the operation end time is the same as the previous time, the reserved operation time is automatically calculated and displayed. There is no need to calculate and input the time again.

[0024]

As described above, the reserved operation method for a washing machine according to the present invention is firstly a method for reserved operation of a washing machine in which the time from the current time to the time at which the operation is to be terminated is displayed as the reserved operation time. After setting the reserved driving time once,
When the next scheduled driving time is set, the reserved driving time is automatically displayed so that the reserved driving ends at the same time as the previous time.If the driving end time is the same as the previous time, the reserved driving time is automatically set. There is no need for the user to calculate the leverage time by himself, which is convenient.

Second, the reservation operation time is displayed by pressing the reservation switch to calculate and display the time from the current time to the same operation end time as the previous operation by the control device. The user simply presses the reservation switch and no other operation is required.

Thirdly, the reserved operation time displayed can be changed by the change switch, so that it is possible to cope with a case where the time to be ended is changed, and it is sufficient to operate only in this case.
