Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a control device for a fully automatic or semi-automatic type electric washing machine used in general households.

Conventional configuration and problems thereof Conventionally, in this type of automatic washing machine, as shown in FIG. As the timer 2 rotates, a cam that controls the load and contacts open and close to execute the washing process, which includes water supply, stirring, etc., and the display device 3 provided on the timer 2 also serves as a progress display. configuration was adopted. 4 is various setting switches.

Here, since the operation of the washing machine itself includes different process times depending on the water supply and drainage conditions, such as the water supply process and the drainage process, the display device 3 of this conventional example does not display the time until the end of all processes. It is difficult to accurately determine the remaining time, it is difficult to prepare for drying after washing, and if clothes are left as they are after spin-drying, wrinkles may appear on the clothes.

Purpose of the Invention The present invention solves these conventional problems, and provides a washing machine that promptly displays the execution time as accurately as possible until the end of the entire cycle, and that makes it easy for the washing machine user to plan the work after washing is completed. It provides:

Structure of the Invention In order to achieve the above object, the present invention includes a setting unit for selecting and setting an arbitrary combination of processes from a washing process, a rinsing process, and a dehydration process, and a washing process selected and set by the setting unit. a control unit for chronologically advancing a combination of a process, a rinsing process, and a dehydration process; a selected washing process, a rinsing process;
The calculation unit includes a calculation unit that calculates the remaining time until the end of the combination of spin-drying processes, and a display device that displays the remaining time calculated by the calculation unit, and the calculation unit is configured to calculate the current washing process, rinsing process, and spin-dry process. The remaining time calculated by the actually measured water supply process time is used to correct the water supply process time during the subsequent washing process and rinsing process, and the remaining time until the end of each process combination after that correction is calculated. The information is displayed on the display device as accurately as possible.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In FIG. 2, 5 is a setting section for selecting and setting each stroke, and 6 is an operation that calculates the remaining time until the end of all strokes according to the settings input by the setting section 5, and also sends load control information to the control section 7. 8 is a load such as a water supply valve, a motor, a drain valve, etc., and 9 is a feedback input device after driving a load such as a pressure switch. Further, 10 is a display device that displays the remaining time calculated by the calculation unit 6, and 11 is a completion indicator.

Further, FIG. 3 shows the specific configuration of the operation display surface part, where 12 is the operation panel surface, 13 is a switch for setting each process such as water flow, washing, etc., and its display part, 13a is for water flow setting, 13b is for washing, 13c is for rinsing,
13d is for dehydration. 14 is a start switch, 15 is a stroke progress display, and 16 is a two-digit numerical display for displaying remaining time, which constitutes the aforementioned display device 10.

To explain the operation in the above configuration, first, after turning on the power switch (not shown), initial settings are set in the setting section 5, and when the start switch 14 is pressed, each stroke is advanced according to the set stroke order. However, the remaining time display is initially calculated by the calculation unit 6 with the water supply time set to 4 minutes, and the remaining time is displayed on the display device 10.

However, once water supply is started by operating the water supply valve in the load 8, the remaining time display content decreases with the execution time, and the actual time is counted until the signal from the feedback input device 9 is input, and the count ends. At that point, the water supply process time of the subsequent process is corrected and calculated again from the initial setting of 4 minutes to real time, and is displayed on the display device 10. Then, the entire process end alarm 11 is sounded.

Further, the drainage process time is also an uncertain time like the above-mentioned water supply time, and similar correction processing is also possible, but the explanation will be omitted here.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the execution time is measured and the remaining time until the end of the entire process is calculated and displayed, and the remaining time can be displayed with high accuracy. Fully automatic or semi-automatic washing is very effective as it makes it easier to carry out the next step, eliminates the need to leave clothes in the tank after spin-drying, and prevents wrinkles from forming on the clothes. We can provide equipment. Also, as mentioned in the example, if you always perform calculation correction using the final measured data,
It can immediately respond to changes in water pressure, etc., and can display the remaining time very effectively and with high accuracy.
