Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device for a washing machine that automatically performs the steps necessary for washing operations such as washing, rinsing, and spin-drying.

Recently, there have been an increase in the number of fully automatic washing machines that automatically perform washing by pressing a button, and as a result, it has become necessary to equip them with many buttons. However, as the number of buttons increases, it becomes difficult for the user to understand which washing course the user has selected, and the number of displays increases, making it expensive and difficult to understand the meaning of the displays.

Regarding the conventional configuration, a button for each program course and a button for an individual program course are provided, and a progress indicator with several light emitting diodes corresponding to each of washing, rinsing, and spin drying is provided. The program was displayed by controlling the lighting of the progress indicator when operating the program button or the button for a single program course.For this reason, many light emitting diodes were used to display the program. It was difficult to understand which buttons to press.

The present invention eliminates the above-mentioned conventional drawbacks and provides a display device that is inexpensive, easy to understand, and allows easy course selection.Examples of the present invention will be described below.

In the figure, (a) and (c) are progress indicators, each consisting of a light emitting diode.

A1. A2. C and E are select switches, among which button A1 is for selecting the standard course, and by simply pressing this button A1, the necessary washing, rinsing, and spin-drying (each step) can be performed. (including drainage operation) automatically progresses.

When you press this button A1, the progress indicators corresponding to the washing, rinsing, and spin-drying steps will appear (99), the display (99) showing the washing process, the display opening (99) showing the washing process, the display opening showing the rinsing process, and the display 99 (b) showing the spin-drying process. are lit respectively, and each progress status is displayed on each progress indicator.

When Matahotan A1 is pressed, the course indicator A1, which is made up of another light emitting diode, also lights up on the indicators A11 and C installed on the top of the select switch, indicating that the standard course button A1 is pressed. do.

Button A2 is for the saving course. When button A2 is pressed, the progress indicators A22B and C light up, and the course indicator A2, which consists of a light emitting diode provided above the select switch, lights up, and the button for the saving course is turned on. Displays that A2 is pressed.

If the button A1 or A2 is pressed - times, the program A2 shown in FIG. 2 will proceed according to the designation of the pressed button A or A2.

Button C is a cut-off button that cuts off all circuits.
Turn off the entire circuit. Also, button B is button A1.
After pressing either A2, the program changes depending on the number of times button B is pressed. That is, when button B is pressed once, the washing is done as shown at B1 in FIG. At this time, only course display A1 or B2 and display A are lit. Next, when button B is pressed once more, the program becomes a washing and rinsing only program as shown in B2. At this time, in addition to the display on the course display d1 or B2, the display 41 is lit. If you press button B again,
As shown in B3, the program is changed to only rinsing and dehydration, and the display ``Port'' and ``No'' are displayed. Furthermore, when button B is pressed, the display C lights up only for dehydration, as shown in B4. Therefore, two types of programs can be selected by selecting the button A1 or A2, and four types of programs B1 to B4 can be arbitrarily selected by pressing the button B and pressing the button A1 or A2.

FIG. 3 shows a configuration in which course indicators a 1 and a 2 corresponding to the above-mentioned buttons are arranged inside the select switch. In the figure, 1 is the button as described above, 2
are contacts and correspond to each button 1.

3 is the above-mentioned course indicator a1. A2 is attached to the printed circuit board 4 and housed in the base 6. 6 is the top mark.

FIG. 4 shows a state in which the select switch is attached to an operating surface 8 on the upper front surface of the washing machine main body 7, and 9 is a washing lid.

As described above, according to the present invention, it is possible to minimize the number of display devices used, display many programs, and
Since it is easy to recognize which course is progressing, it is extremely easy to operate.
