JPS586332A - Cooking oven - Google Patents

Abstract

PURPOSE:To eliminate a touch panel and as well as improve the handleability by a method wherein inputtable keys are displayed on a cathode ray tube visual display unit and the selection of the key is performed with a light pen in the cooking oven having the cathode ray tube visual display unit. CONSTITUTION:The cooking oven 1 is so constituted that the cathode ray tube visual display unit 4 is provided in a front operational panel board and the selection of various keys displayed on the display unit 4 is performed with the light pen 5. When the power supply is put to work, at first, the hour is displayed and the adjustment of the hour is performed under the displayed state with the light pen 5. After the hour is adjusted to the correct time display, the pictures showing the kind of meal is displayed so as to select either one of a Japanese, a European or a Chinese dish. In this instance, when, for example, a European meal is selected, a menu for a European meal is next displayed as illustrated in the attached drawing. After that, when the number key, which designates the required menu, is selected with the light pen 5, the picture of the required menu is displayed and then the cooking of the required menu is started.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a configuration in which input is conventionally input to the cooking oven from a touch panel, keyboard, etc., but the physical switches can be reduced as much as possible or even completely eliminated. The information is displayed on the CRT display each time.
It is intended to provide a cooking oven that allows selection input with a light pen.

Recently, micro combi coaters have been introduced into consumer equipment.
Cooking in the oven, microwave, etc. is a must. For example, as shown in Figure 1: Sea urchin? Some Ii ranges 1 are provided with a display section 2 made of a fluorescent display tube or the like and a keyboard (touch panel) 3 as an input section on the front operation section. However, the usability of cooking ovens with such a configuration is inconvenient as the functions become more complex and the number of types of input sections increases. The present invention
The CRT display and light pen improve the usability of a cooking oven. Hereinafter, one embodiment of the present invention will be described in detail.

FIG. 2 is a general view of a microwave oven showing an embodiment of the present invention, in which numeral 4 indicates a CRT surface, and numeral 6 indicates a light pen. FIG. 3 shows the display state of the CR1 display section 4.
Figure a is an example of a case where the "hourly open setting" is made without switching when the power is turned on. The time is from ○○:00 to 24:00-4
Therefore, to indent 41 digits in order, number keys φ+' + 2+..., 8, 9 and "Cp, Ock" [cnock J key, Then, the Be5etJ key is required to cancel the set numerical value. Therefore, l'cffoc is displayed at the bottom of the screen of CR1 display section 4.

+ ``'' + ``8'', ``9'' keys 2 < 7 + < L, Lie I pen 5 can press either key of this C. Next, when the clock (time opening) setting is completed, the display screen will be as shown in Figure 3, and the screen for selecting the type of dish will appear in 1. 11th wind, 2. Western style, 3. You can choose either Chinese style. Also, if you want to return to the screen in Figure 3 a (first setting), press the EXIT key 'X'' manually. .3 and +X II Goat - Display and select these with the light pen. In FIG. 3, the menu can be selected on the display screen after the type of food has been determined. For example, if you select 2 Western style when displaying, roast beef will be displayed.

Menu dishes such as gratin... - are displayed. In this case, the keys are displayed as the cooking menu number, EXIT key 1 to return to the initial settings screen, the next screen (H on the screen of the menu), and the previous screen. ↓ as the key to select (both sides in front of the food menu).

All you have to do is display the key f. FIG. 3D shows the screen shown in FIG. 3C when light pen 1 is selected and roast beef is selected. At this time 1. This is a selection screen for automatic cooking (cooking based on already stored data) or 21 manual cooking (inputting data manually). Furthermore, it is sufficient to display only the 'x' key, numeric keys 1 and 2, and the 'x' key, which return to both sides of the initial settings, as key displays.
Select automatic cooking (on the screen at 7, the data that has already been stored is displayed. This means cooking for 18 minutes and 30 seconds. In this case, the only key display is the "5TART" key 1 to indicate whether to star or not, or the "x" key to indicate whether to return to the initial setting screen in FIG. 3a. Figure 3 f shows the screen when manual cooking is selected in Figure 3 d.

Power selection keys such as the power key and the "LoW" key will be displayed. In this way, the minimum required keys are displayed on a part of the CRT display according to the screens that are displayed sequentially one after another. I decide to go.

As described above, the present invention eliminates the conventional keyboard section as an input section of a cooking oven, and displays the minimum necessary key information according to the screen displayed each time. The selection is made using a light pen, and the following effects can be obtained.

1. The touch panel of the input section, which had to be manufactured every time the function of the cooking oven changes, is no longer required, reducing costs.

2. Ease of use of the cooking oven - 2. It is convenient because only the minimum necessary type of key information can be displayed and selected each time, whereas there were conventionally many types of key information.
