Abstract

PURPOSE:To prevent the washing time from being unconditionally extended by the change of the washing time by providing a timer means measuring the washing time and a comparing means comparing the measured time and the time set by a switch setting the washing time for control. CONSTITUTION:A microcomputer 7 judges via the stored program whether a switch setting the washing time is pushed or not and changes the washing time if it is pushed. The microcomputer 7 compares the elapsed time after the washing is started until the washing time is changed and the set time after the change, it clears the elapsed time only when the set time after the change is smaller than the elapsed time, after the change washing is performed based on the newly changed set time. When the set time after the change is larger than the elapsed time, washing is performed based on the set time changed after the start of washing.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a washing machine control device.

Conventional technology Conventionally, if the washing time setting was changed during the washing operation, the elapsed time from the start of wash 1 until the change was made was ignored, and the changed setting was changed from the time of the change. I was doing laundry for an hour. 3 Problems to be solved by the invention In such conventional methods, after the user starts washing,
If you make a change to increase the washing time in the middle, the time from the start of washing to the time of making the change must be cleared before making the change, so the problem is that the washing time will actually be longer than the set time after the change by the elapsed time. had.

The present invention is intended to solve such a problem, and the purpose of the change during washing is to change the washing time based on the time from the start of washing.

Means for Solving the Problems In order to achieve the above object, the washing machine control device of the present invention includes a switch for setting a plurality of washing times, a monitor for driving a pulsator, and a timer means for measuring washing times. and a comparison means for comparing the clocked time of the timer means with the washing time set by the switch, and a control means for controlling the motor by inputting the comparison means, the comparison means The washing time changed by the switch is compared with the time on the meter side, and when the changed washing time is greater than the time on the meter side, the output is output when the changed washing time and the time on the meter side match. There is.

With this configuration, even if the washing time is changed midway through, if the changed washing time is longer than the time measured by the comparison means, the washing time that has been executed so far is subtracted from the changed washing time. You will only have to do the laundry for the remaining time.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In FIG. 1, 1 is a switch for setting the washing time. 3 is a display means which displays the washing time based on the time setting of switch 1. 4 is a motor that drives the pulsator. Reference numeral 6 denotes a timer means for measuring time from the start of washing, and outputs the time to the comparison means 6. The comparison means 6 inputs the set time from the timer means 6 and the switch 1 via the control means 2, and outputs a washing completion signal to the control means 2 when these two values match.

The control means 2, timer means 6, and comparison means 6 are constituted by a microcomputer 7 as shown in FIG.
The microcomputer 7 changes the washing time, drives the motor, etc. according to a built-in program. moreover,
The microcomputer 7 includes an input section 7b for inputting the switch 1 and a storage section 7a for storing the timer value.
and a control section 7d which controls the washing time display means 3a to 3C of T1 to T3 and an output section 7C which outputs an output signal to the motor 4, the input section 7b, the storage section 7a, and the output section 7C, and performs data comparison calculations. It is equipped with the following.

Next, the operation of this embodiment will be explained using the microcomputer 7 shown in FIG.
This will be explained according to the control flow. The microcomputer 7 determines whether or not the switch for setting the washing time has been pressed in step 21, and if the switch has been pressed, the process proceeds to step 22.
Change the washing time (T1→T2). Here, T1 is the setting time before the change, and T2 is the setting time after the change. Furthermore, the microcomputer 7 calculates the elapsed time t from when washing is started until the change is made in step 23, and the above-mentioned T.
If t>T2, that is, if the set time T2 after the change is smaller than the elapsed time, the elapsed time t is cleared in step 24, and after the change, a new 12
Do laundry for hours. therefore.

If t<T2, washing will be performed for T2 hours after the start of washing.

According to the above embodiment, if the user changes the washing time midway through and increases the set time, the washing time will always be set from the time the washing starts, thus avoiding washing for an extra time. . Also, even if you reduce the set time, if the time after the change has not passed since the start of washing, washing will continue for the remaining time, and if it has, washing will continue for the new set time. At the same time, there is no inconvenience that the washing ends.

Effects of the Invention As is clear from the above embodiments, according to the present invention, a switch for setting the washing time, a timer means for measuring the washing time, and a washing time set by the timer means and the switch are provided. Since the washing machine is equipped with a comparison means for comparison and control, even if the washing time is changed during washing, the washing will be completed once the changed washing time including the time measured so far has elapsed. Therefore, changing the washing time prevents the washing time from being extended unconditionally, making it possible to appropriately execute the set washing time.
