Abstract

PURPOSE:To enable setting in a separate setting changeover order and improve the usability for a user by measuring the time until a switch for giving the set signal of a washing program is pushed again and varying the range of setting the program based on the data of a timer means. CONSTITUTION:A microcomputer 6 judges whether a washing setting changeover switch 5a is pushed and, when not pushed, it counts a timer and waits for the switch 5a to be pushed. When the switch 5a is pushed, it judges whether it took two or more seconds until the switch is pushed this time. When no more than two seconds is elapsed, judgement is formed that the switch is being intermittently pushed and that in the course of the changeover of program setting, thereby setting to an ordinary program setting changeover loop, i.e., 'cut' to '15'', '15'' to '12'', '12'' to '9''.... When two or more seconds is elapsed, it is judged whether the setting of washing time is in the 'cut' condition or not and, when in the 'cut' condition, setting to the '12'' of high using frequency is carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a washing machine control device using a microcomputer or the like.

2. Description of the Related Art Conventionally, in the washing program of a washing machine, the user is generally allowed to freely set the number of times, nine times, etc. for each step of washing, rinsing, and spin-drying. For example, as shown in FIG. 3, if it is time for washing, the display on the washing display section 20 can be changed from "off" to "15 minutes" using one switch.
(Hereinafter, minutes will be expressed as l) - "9 勺 - rf3'J - r
The settings were changed sequentially, such as "3'J-r off", forming one setting switching loop.

Problems to be Solved by the Invention In the conventional setting of washing time, the next time after "cut" is "cut".
16', but the ones most frequently used by normal users are l'12'J or '9', and '15'J'.
The problem was that it was inconvenient to use because it did not have the following settings. However, after "cut", "12'" or "
If a setting loop was used to bring in ``9''', it would be impossible to set ``16''', which would cause an inconvenience.

Means for Solving the Problems In order to achieve the above object, the present invention provides washing and rinsing based on a set washing program.

A control means for performing a dehydration process, a plurality of switches that provide setting signals for various washing programs to the control means, and a timer means for measuring the time from when this switch is pressed until when the same switch is pressed again. The control means is configured to vary the settable range of the affirmative program based on the data of the timer means.

Effect: With the above configuration, the timer means can detect the time from when a switch is pressed until the same switch is pressed again, so the control means determines whether this time is greater than or equal to a predetermined reference value, and the control means determines whether this time is greater than or equal to a predetermined reference value. Based on this, it becomes possible to set program settings other than the predetermined constant setting switching loop.

Embodiment A control device for a washing machine according to an embodiment of the present invention will be explained with reference to FIG.

In FIG. 1, water supply valve 1. Motor 2. The washing, rinsing, and spin-drying processes of the washing machine are operated by the combination of the driving operations of the drain valve 3, and the program settings for each process can be changed by the switch unit 6, and the program settings are displayed on the display unit 4. is displayed. For example, the switch 5a is used to change the washing time, and each time the switch is pressed, the washing time on the display section 4 is sequentially set. Reference numeral 6 denotes a microcomputer constituting a control means and a timer means, which includes an input section 6a for inputting the switch section 5, and the water supply valve 1. Morph 2. The drain valve 3 is driven, and the display section 4
an output section 8b that outputs an output to display program settings; and a storage section 6c that stores the state of the switch section 52 and the display section 4.
, the input section 6a.

It has an arithmetic control section 6d that controls an output section 6b and a storage section 6c.

Next, the control of the microcomputer 6 of the above embodiment is controlled by a second
This will be explained with the help of a diagram.

The microcomputer 6 determines whether the washing setting changeover switch 5a is pressed in step 11, and if it is not pressed, it counts the timer in step 12, returns to step 11, and waits for the switch 6a to be pressed. If is pressed, the value of this timer, that is, switch 6I! It is determined whether the time from when 1 was pressed last time until it is pressed this time is 2 seconds or more. If more than 2 seconds have not elapsed, it is determined that this switch has been pressed intermittently and the 10g setting is being changed, and in step 15 the normal program setting switching loop knob is turned from OFF to 15'. J.

115' - 12', 12' → 9...
Make settings like this.

Returning to step 13, the microcomputer 6
If two seconds or more have elapsed, it is determined in step 14 whether the washing time setting is "off". In the case of "off", it is determined that the setting has been left as "off" for a while, and in step 1e, a setting different from the normal switching loop, for example, "12'" is set. If the setting is not "off", normal settings are made in step 16.

Finally, the microcomputer 6 performs steps 16 and 1.
After step 6, the timer is reset in step 1T, and the process returns to step 11, where it waits for input from the switch 5a.

According to the above embodiment, based on the time from when the switch 1 is pressed to when the switch 1 is pressed again when changing the setting of the washing time, the washing time changes from "off" to normal [1ts'J].
It is possible to set the setting to "12'" which is frequently used or set, and it is possible to improve usability for the user. In addition, although the above embodiment described washing time switching, it is also possible to apply this to switching between rinsing and spin-drying.

Effects of the Invention As is clear from the above embodiments, according to the present invention, washing, rinsing, and
A control means for performing a dehydration process, a plurality of switches that provide setting signals for various washing programs to the control means, and a timer means for measuring the time from when this switch is pressed until when the same switch is pressed again. The washing program can be set by the control means to be variable based on the time of the timer means, and the washing program can be set in a different order from the normal setting change order. User-friendliness can be improved.
