Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation display device for an electric cooker provided with various operation switches and a liquid crystal display unit, such as a microcomputer-type rice cooker.

[0002]

2. Description of the Related Art FIGS. 2A and 2B show an example of an operation display unit in a microcomputer-type rice cooker. In the figure, reference numeral 1 denotes an outer body of a jar, 2 denotes a window hole, and an operation display device 3 is provided inside the window hole 2. The operation display device 3 includes a liquid crystal display unit 5 supported by a frame 4, a touch panel 7 overlaid on the surface of the liquid crystal display unit 5 via a printing sheet 6, and a backlight 8 provided on the back surface of the liquid crystal display unit 5. It consists of.

The print sheet 6 is provided with a function switch display 9 in which characters such as "menu", "clock", and "heat retention" are printed on a transparent square colored portion. A function switch 11 such as a menu switch, a clock switch, and a warming switch is configured by the portion of the touch panel 7 overlapping the front surface. The portion where these function switches 11 are provided constitutes a touch operation area 12 on the touch panel 7. Touch operation area 1
The portions of the printing sheet 6 and the touch panel 7 other than 2 are transparent, so that the liquid crystal display unit 5 can be seen through,
This portion constitutes the liquid crystal display area 13.

[0004] The backlight 8 illuminates the liquid crystal display area 13 through the liquid crystal display section 5 and also illuminates the touch operation area 12 through the liquid crystal display section 5.

[0005]

Since the touch operation area 12 is provided with a plurality of function switches 11, it is necessary for the user to select a desired one of the function switches 11 and perform a touch operation. . It is desired that the selection operation can be performed without error from the viewpoint of improvement of operability.

However, in the conventional function switch 11, the elements for distinguishing the function switches 11 from each other are mainly coloring or characters of the function switch display 9, and the illumination light from the backlight 8 emits the light from each function switch. Could not be a discriminating factor because it is common to Further, when the function switch 11 is touch-operated, it is not possible to display only the function switch 11 by blinking or the like to indicate that the touch operation has been performed, and there is a problem in operability.

Therefore, the present invention provides a touch operation area 12
To be illuminated by an illumination light source independent of the liquid crystal display area 13 so as to solve the above problem.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a touch operation area in which a touch panel is superimposed on a surface of a liquid crystal display unit, and the touch panel is provided with a translucent function switch display. In the operation display device of the electric cooker provided with an illumination light source on the back surface of the liquid crystal display unit, the touch operation region is provided outside the liquid crystal display region, and on the back surface of the touch operation region. An illumination light source different from the above illumination light source was provided.

The function switch display is displayed with a plurality of different contents, an illumination light source for the touch operation area is provided for each function switch display, and a light emission color of each function switch display by the illumination light source is set to a function. Different configurations can be taken for each switch.

Further, the function switch display is displayed with a plurality of different contents, an illumination light source in the touch area is provided for each function switch display, and the illumination light source changes its lighting state by a touch operation. May be caused.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to FIG.
It will be described based on. FIG. 1 shows an operation display device of a microcomputer-type rice cooker similar to the above-described conventional example, in which an operation display device 3 is provided inside a window hole 2 of an exterior body 1. The operation display device 3 includes a liquid crystal display unit 5 supported by a frame 4, a touch panel 7 overlaid on the surface of the liquid crystal display unit 5 via a print sheet 6, and an illumination light source provided on the back surface of the liquid crystal display unit 5. It is constituted by a backlight 8.

The print sheet 6 is provided with a function switch display 9 in which characters such as "menu", "clock", and "heat retention" are printed on a transparent square colored portion. The function switch 11 such as a menu switch, a clock switch, and a heat retention switch is constituted by the touch panel 7 and the portion of the touch panel 7 overlapping the front surface thereof. The portion where these function switches 11 are provided constitutes a touch operation area 12 on the touch panel 7. The print sheet 6 other than the touch operation area 12 and the touch panel 7
Is transparent so that the liquid crystal display unit 5 can be seen through, and this part constitutes the liquid crystal display area 13.

The above configuration is the same as the conventional case,
In the case of the present invention, the touch operation area 12 provided on the touch panel 7 is arranged outside the liquid crystal display unit 5, and one hole for each function switch 11 is provided in the frame 4 on the back surface of the touch operation area 12. 14 are provided, and one light emitting diode 15 as an illumination light source for the touch operation area is provided on the back side of each hole 14. The light emitting diode 15 is provided with a red,
Light emitting colors such as orange and green are used. If there is insufficient light emission color, the same color is partially used and the function switch display 9
By changing the color of the coloring, the emission color of each function switch 11 may be identified.

The above-mentioned light emitting diode 15 illuminates each function switch 11 from the back by turning on all of the light in conjunction with the backlight 8, so that the function switch 11 is turned on.
Each emits a different emission color to the outside. Thus, the user can identify each function switch 11 not only by the characters and coloring of the function switch display 9 but also by the emission color thereof, and can perform a touch operation without error.

Each of the function switches 11 indicates that a touch operation has been performed by changing the lighting state, such as changing from lighting to blinking or increasing the amount of emitted light, when the user performs a touch operation. You may make it.

[0016]

As described above, according to the present invention, the various function switches provided on the operation display device of the electric cooker such as a rice cooker are made independent of the liquid crystal display area, and the function of the liquid crystal display area is reduced. The illumination switch is illuminated by the illumination light source in the touch operation area different from the backlight, so the function switches can be illuminated in a different way from the liquid crystal display area, improving the operability of the function switches. Can be done.

In particular, the illuminating light source for the touch operation area is provided for each function switch, or the emission color is different for each function switch, so that the discriminability is improved and the operability is further improved.
