Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a heating cooker, and more particularly to a heating cooker that efficiently sets heating conditions during cooking, such as heating time, heating temperature, and weight of food, without making mistakes. It is something.

Configuration of conventional example and its problems In conventional heating cookers, heating time, heating temperature, and weight of food are set, and cooking is performed based on the set conditions. The time, heating temperature, and weight of the food were set by rotating a timer knob and displaying numerical values on the display for the time corresponding to the angle. Therefore, in order to rotate the timer knob while looking at the numerical value displayed on the display, the user must keep staring at the display until the desired time is displayed. Also, if you fall, you will end up turning the timer volume too much, and you will have to turn the timer volume back again. Therefore, it is not easy to use for people such as ordinary housewives.

FIG. 1 shows a perspective view of a microwave oven as a conventional cooking device. Reference numerals 1 to 8 are operating sections, 9 is a door that can be opened and closed to take food in and out of the heating chamber, and 10 is a main body.

FIG. 2 shows an enlarged view of the operating section. 1 is a display section that displays the heating method and cooking menu, as well as heating time and heating temperature, 2 is a menu board that displays menus that can be automatically cooked, and 3 is a menu selection key arranged corresponding to each menu. , 4
5 is a heating method selection key for selecting a heating method, and 5 is a timer for setting the heating time, which is required to set the heating time when the heating method is selected. In this case, the timer 5 will appear on the display section 1.
The heating time corresponding to the angle is displayed, and the user needs to set the angle of the timer 5 while looking at the numerical value on the display section 1. A heating temperature setting key 6 is used to set a control temperature for a heating method selected by the heating method selection key 4 that requires temperature control. A cooking start key 7 is used to start cooking after the selection and setting of the menu selection key 3, heating method selection key 4, timer 5, or heating temperature setting key 6 is completed. Reference numeral 8 is a cancel key for canceling the selected menu being set, heating method, heating time, etc. Furthermore, during cooking, heating can be stopped using this cancel key. In this way, the timer 5 or heating temperature setting key 6 and the heating time and heating temperature display section 1
Since the locations of the buttons are different, it is necessary to operate while looking at multiple locations. Furthermore, while the timer 5 has an analog setting method, the display of the set heating time is a digital display, which gives an inconsistent feeling and is difficult to use.

Figure 3 shows the display contents at that time. FIG. 3A shows the display during automatic cooking, and is the display when the second key of the menu selection keys 3 is selected and input. “Auto” in the display contents of display unit 1 indicates automatic cooking mode, and “2” indicates reheating of “Simmered dishes/Rice bowl dishes” which is the second menu from the top of menu board 2. are doing.

FIGS. 3B and 3C show the contents of the display unit 1 when the user sets the heating method, heating time, and heating temperature instead of automatic cooking. In B, "Electric High" was selected from the heating method selection key 4, and then the timer 5 was rotated to set a heating time of 13 minutes. Also, C selects "oven" as the heating method, then sets 25 minutes as the heating time with the timer 5, and then sets the control temperature during heating with the heating temperature setting key 6.
This is the display when the temperature is set to 180℃. in this case,
The positions of the selection keys, timer and setting keys and the display are different, making it very inconvenient to use.

As described above, in conventional heating cookers, the positions of the display section, timer setting section, and heating temperature setting section are different, so it is necessary to operate the device while looking at multiple locations, which makes it inconvenient to use. Furthermore, while the display is digital, the settings are made in an analog manner, which creates an incoherent feel and makes it difficult to use.

Purpose of the invention The present invention solves the above-mentioned conventional problems.
By displaying heating time, heating temperature, food weight, etc. in analog quantities, and by providing a transparent setting input device that is superimposed on the same position as the display and allows the display contents to be recognized, it is no longer possible to check multiple points in the past. The aim is to create a heating cooker that is easy to use, eliminates the confusion of making multiple selections, and also eliminates the disparate feeling of conventional products by using analog display on the display.

Structure of the Invention In order to achieve the above object, the cooking device of the present invention includes a display means for displaying heating time, heating temperature, and weight of food in analog quantities, and a transparent display means on the front surface of the display means for displaying the analog quantities. An input means is provided that has electrodes that allow the display amount of the display means to be recognized, and the relationship between the position of the display amount of the display means and the position of the input amount of the input means is the same, and the desired display amount can be directly determined.

FIG. 5 is a block diagram showing the structure of a heating cooker according to an embodiment of the present invention. Various commands from the operating section 11 are input to the microcomputer 12. The microcomputer 12 controls the heating source and the like based on this command. When a heating method or a cooking menu is selected, the microcomputer 12 outputs a predetermined display to the display section.
A liquid crystal display, a fluorescent display tube, or the like is used as the display section. 13 is a display driver for this liquid crystal or fluorescent display tube. This liquid crystal will be explained in detail later. Next, the user finishes setting the heating method, cooking menu, and heating time, and then presses the start key 7.
When pressed, the microcomputer 12 starts supplying power to the magnetron 17 via the output control circuit 15. Then, cooking of the food 21 in the heating chamber 16 begins. 23 is a turntable motor for rotating the food 21 to improve uneven heating, and 18 is a fan motor for cooling the magnetron 17 and ventilating the inside of the heating chamber 16.

As the cooking progresses, steam and various gases are generated from the food 21. The heating progress of the food 21 can be detected by the gas sensor 19 (humidity sensor or gas sensor) disposed within the exhaust guide 24. 14 is a detection circuit of the sensor 19. The microcomputer 12 determines the end of cooking using this sensor 19, automatically stops power supply to the magnetron 17, and notifies the user of the completion of cooking. Note that as a sensor, an infrared sensor that detects the surface temperature of food, a thermistor that monitors the temperature of intake and exhaust air, etc. can of course be used.

During oven cooking and grill cooking, the heater 20 is energized, and the thermistor 25 as a temperature sensor controls the temperature of the heating chamber.

Next, FIG. 6 shows a liquid crystal 26 as a display element of the display section. The light transmittance of the liquid crystal 26 changes by controlling the applied voltage. FIG. 6A shows a case where the applied voltage is small and light is blocked, and FIG. 6B shows a case where the applied voltage is increased and light is transmitted. Then, as shown in C, a display board 2 with display contents printed on the rear of this liquid crystal 26

FIG. 7 shows the operation at this time. A and B are not displayed when the light is blocked,
C and D are cases in which light is transmitted, and the contents of the display board 27 can be seen. By making such a transparent portion correspond to the display portion as shown in E, it is possible to display a necessary portion. In other words, display board 2
7 has a bar-shaped portion corresponding to the analog quantity, and scales are printed on both sides of the bar. The left side is the time scale up to 15 minutes, and the right side is the temperature scale up to 200°C. Such a configuration enables display as shown in F.
In this case, the liquid crystal at the position corresponding to the time scale is transmitted through, while the temperature scale side is blocked. Then, the display area of the central bar-shaped liquid crystal can be divided into units, and only the necessary areas can be displayed.

The structure of the operating section according to FIG. 8 is shown. A transparent switch 29 is provided in front of a liquid crystal 26 and a display board 27 serving as a display section. This transparent switch uses a transparent sheet on which indium oxide, gold, etc. are wired in the required patterns, and these patterns are transparent and conductive. Furthermore, since the transparent switch 29 is a sheet, the force applied when it is pressed during input is applied to the liquid crystal 26, so there is a risk that the liquid crystal 26 may be destroyed. Therefore, the liquid crystal 26 is protected by inserting a transparent plate 28 in order to receive this force.

FIG. 9 shows the structure of the transparent switch 29. 2
It is composed of two sheets 291 and 292. A pattern 293 is wired on this sheet using a transparent and conductive material such as indium oxide or gold. These sheets 29
Nos. 1 and 292 are pasted together with a constant spacing between them, and with their patterned surfaces facing each other. This pattern is wired to correspond to the position of the display content.

FIG. 10 is an enlarged view showing all the displays on the operation section 11 of the heating cooker according to an embodiment of the present invention.

The enlarged view shown in the figure shows the case where all display elements are displayed, and in reality, only the necessary ones are displayed. Analog display section 32 that shows the heating time, heating temperature, and weight of the food
will be explained below.

First, the analog display section 32 on the left has a scale of 0.
There is a food weight scale from 0 to 500g and a 50-minute timer scale from 0 to 50 minutes. Then, one of these scales is displayed, and correspondingly each quantity is displayed on the bar-shaped display section in the center. The analog display section 32 on the right side similarly displays either the heating temperature from 130°C to 250°C or the 15 minute timer from 0 to 15 minutes. By providing a transparent input section on the front side of the display section, each heating time, heating temperature, weight of food, etc. can be set by directly inputting them into the display section.

An example of the operation will now be shown in the order of FIGS. 11 to 14. As shown in FIG. 11, initially only the cooking category section 30 is displayed. Therefore, as shown in FIG. 12, if the user directly selects the position where the manual is displayed in the cooking category section 30, the other cooking categories disappear and only the manual is displayed. At the same time, "Electric High", "Electric Low", "Grill", and "Oven" are displayed as manual heating methods in the heating method/cooking menu section 31. Then, as shown in FIG. 13, by directly selecting "Electric Weak", the other heating methods disappear and only "Electric Weak" is displayed. Further, the analog display section 32 displays a 50-minute scale as a timer necessary for "Electric Weak".
By directly inputting the 20 minute position on the scale, up to the 20 minute position is displayed on the analog display section 32. In this way, by displaying the display in analog quantities, by arranging a transparent input section in front of which the display quantity can be recognized, and by making the position corresponding to the display quantity the same as the positional relationship between the input quantity, The effect of improving usability is to eliminate the confusion of turning a timer while looking at the digital display as in the past, and to simply input data directly to the display and the current display is displayed in analog quantities. has.
