DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention is used in ordinary households.
The present invention relates to a display device of an electric cooker such as an electric water heater.

[0002]

2. Description of the Related Art In recent years, the spread of electric cookers has been remarkable.
Among them, so-called "all-electric homes" in which all the energy in the home is provided by electricity are increasing. Also, with the aging society in earnest, safe and easy-to-use electric cookers are desired.

[0003] A display device of a conventional electric cooker will be described below. FIG. 7 shows a display device of a conventional electric cooker, which is an external appearance of an operation portion of a display device applied to an electric water heater. In FIG. 7, when a "water heater" key 1 is pressed, a water heater mode is set, and a red light emitting element 2 for operation display is turned on. When the heating is completed, the mode shifts to the warming mode, in which the light emitting element 2 is turned off and the light emitting element 3 is turned on. When the key 4 is pressed, the heat retention temperature is switched to a slightly lower temperature, and the display is replaced with the light emitting element 5. Orange is used for the light emitting elements 4 and 5. The key 6 is a "rest" key for stopping water heating and heat retention for a predetermined time. When pressed, the power supply to the heater is stopped and the light emitting element 7 is turned on. The light emitting element 7 uses a green color to give a sense of security.

[0004]

However, in the above-described conventional configuration, an orange light-emitting element is used to display the warming operation mode. However, some people turn on or off the light. Or it is difficult to identify which of the two light emitting elements is lit. That is, recent research has revealed that it is difficult for elderly people with advanced cataracts to see a yellowish display on a whitish background.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a display device of an electric cooker which is easy to identify and has excellent usability.

[0006]

According to the present invention, in order to achieve the above object, a first means comprises a plurality of light emitting elements which emit light of different colors, a driving means for driving these light emitting elements, A light-emitting element selected by the user, the light-emitting element being selected by the user. Use to display the operation mode ,
Which color light emitting element of the light emitting element is used depending on usability
It is possible to select whether to use .

The second means includes a lighting / flashing selection means which allows a user to instruct the driving means to light or blink the light emitting element. The operation of the operation selected by the lighting / flashing selection means is provided. The operation mode is displayed.

[0008]

According to the present invention, the above-described configuration allows the user to use the camera easily.
Since the color of the light-emitting element for displaying the operation mode can be selected according to the hand , even for elderly people with advanced cataracts, the ease of use is improved by selecting colors that are easy to identify.

When the number of easily distinguishable colors is small,
By selecting whether the light emitting element is lit or blinking, usability can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the first means for solving the problems of the present invention will be described below with reference to FIGS. FIG.
, The drive means 8 displays the water heater mode LE
D9 (red) is connected to the terminal 8a. Also, the LED 10 (orange) and L which indicate the normal higher heat retention mode
The ED 11 (red) is connected to the terminal 8b, and the LED 12 (orange) and the LED 13 (red) for displaying the lower heat retention mode are connected to the terminal 8b.
LED1 that is connected to "c" and displays the "rest" mode
4 (green) is connected to the terminal 8d. And the LE
D10 and D12 are connected to the transistor 1 via resistors 15 and 16.
7 and the LEDs 11 and 13 are connected to resistors 18 and 19
Through the transistor 20. The LE
D9 and D14 are connected to both transistors 17 and 20 via resistors 21 and 22, and 23 and 24, respectively.
The transistors 17 and 20 are connected to terminals 8e and 8f via resistors 25 and 26, respectively. Also, the emission color selection means 2
The output of 7 is also input to the driving means 8. FIG. 2 shows the appearance of the operation unit, and the same components as those in the above-described conventional example are denoted by the same reference numerals and description thereof will be omitted. LED10 and L
ED11, LED12 and LED13 are integrated, and are two-color light emitting LED housed in one package.
, And are disposed in the light emitting units 29 and 30. LED9 and L
The EDs 14 are individually arranged in the light emitting units 31 and 32, respectively.

Next, the operation will be described. When a color changeover switch 28 provided on the operation unit is operated, a signal is transmitted to the driving means 8 via the emission color selecting means 27, and an instruction is given to which of the transistors 17 and 20 is turned on. When the color changeover switch 28 is now on the I side, the transistor 17 is turned on, and the orange LED 10 or 12 is used to display the warming operation. On the other hand, when the color switch 28 is on the II side,
Is turned on, and the same red LED 11 or LED 13 as the water heater mode is used for the display of the warming operation.

As described above, according to this embodiment, the color of the mode display can be selected using the emission color selection means 27.
For elderly people with advanced cataracts, it can be displayed in easy-to-understand red instead of orange, which is hard to identify.
The usability is improved.

Next, a second embodiment of the present invention will be described with reference to FIGS. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. When the flashing changeover switch 33 provided on the operation unit is operated, a signal is transmitted to the driving unit 8 via the lighting / flashing selection unit 34. Flashing switch 34
When it is on the III side, the display is normal instead of blinking.
When the blinking changeover switch 34 is on the IV side, the display uses blinking as shown in FIG. In the water heater mode, the LED 9 (red) blinks slightly faster. In this embodiment, it is turned on for 0.5 seconds and turned off for 0.5 seconds. In the heat retention mode at a higher temperature, the LED 11 (red) blinks slightly slowly. In this embodiment, it is on for 5 seconds and off for 5 seconds. In the warm mode at a lower temperature and the rest mode, the lamp remains lit.

As described above, according to the present embodiment, the display can be switched between lighting and blinking by the lighting and blinking selection means 34, so that misreading can be prevented even if the same color is used for the display. .

Next, a third embodiment of the present invention will be described with reference to FIG. The same components as those in the second embodiment are denoted by the same reference numerals, and description thereof is omitted. In FIG. 6, a diode 3 is provided from the output 27b of the emission color selection means 27 to the output 34b of the lighting / flashing selection means 34.
5, the signal can be transmitted through the switch 5. If the color changeover switch 28 is set to the II side, the display using the blinking can be automatically performed even if the blinking changeover switch 34 is set to the III side. .

[0016]

As described above, according to the present invention, a plurality of light emitting elements which emit light of different colors and a light emitting color selecting means for selecting and instructing which color of the light emitting elements to use for operation display are provided. Thus, it is possible to realize an excellent electric cooker display device capable of selecting the color of the light emitting element for displaying the operation mode. In addition, by having a lighting and blinking selection means for selecting and instructing whether to light or blink the light emitting element, when different modes are displayed using light emitting elements of the same color, the mode can be distinguished between lighting and blinking, An easy-to-use display device for an electric cooker can be realized.
