Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to improve the usability of a cooking device equipped with a plurality of heating means such as a high frequency heating means and a heater heating means.

In recent years, microcomputers (hereinafter referred to as microcomputers) are used to control complex cooking devices that include both high-frequency heating means and heater heating means, and display tubes are used to display the output.

In other words, the microcomputer controls the heating means, its output, heating time, heating chamber temperature, etc.
The contents are displayed on the display tube of the operation panel. However, in this case, the display contents are displayed in one color, for example, blue-green, so it is difficult to distinguish which of the display contents is displaying heating time or heating temperature, for example. It was bad.

The present invention eliminates these conventional drawbacks, and one embodiment of the present invention will be described below with reference to the accompanying drawings.

This embodiment shows a composite type high-frequency heating device that has the function of raising the temperature in the heating chamber to a high temperature using a heating element and cooking food. In FIGS. 1 and 2, 1 is the main body of the high-frequency heating device, 3 is a door provided in the front opening of the heating chamber (not shown) in the main body 1 so that it can be opened and closed freely; 3 is an operation panel;
The details are shown in the figure. In other words, in Fig. 2, 4 is a cooking start button, and 5 is a display section (displaying the heating method, heating time, time, set temperature of the heating chamber, actual temperature, etc.), "Automatic", "Electric High",
"Electric Low" heating time is displayed in blue-green, "Grill" and "Oven" temperature scales are displayed in red) 6 is the keyboard (to select the heating method), 7 is the blue time adjustment knob (also used to set the time) , 8 is the red temperature control knob, 9 is the heating element (heater) switching knob, 1
0 is a clock button (used when setting time).

The control circuit in this embodiment is shown in Figure 3.
When heating for a minute, (1) First, press “Electric High” on keyboard 6 in Figure 2.
When is pressed, a signal is sent to the electronic control circuit 11 in FIG. 3 including the microcomputer, the relay 12 is activated, the oven lamp 13 is turned on, and the display tube 5a corresponding to "Electric Strong" on the display tube 5 turns blue-green. Light.

(2) Next, turn the time adjustment knob 7 shown in FIG. 2 to set "1000" on the display tube 5b corresponding to the time on the display section 5. (The display on the display tube 5b is blue-green).

(3) After that, when the cooking start button 4 is pressed, the start signal switch 14 shown in FIG. 3 operates, and then the door monitor switch 15 and the oscillation stop device 1
6/17 will be closed. Start signal switch 1
4 and door monitor switch 15 operate, it becomes a start signal to the microcomputer, and the relay
18 and relay 19 operate and high voltage transformer 20
Electric current flows through the primary coil of the magnetron 21, and high frequency waves are generated to heat the food in the heating chamber.

(4) Then, the time on the display section 5 counts down from 1000 every second, and the "Electric Power" on the display tube 5a also flashes. In addition, 22 in FIG. 3 is the upper heater, 23
24 is the lower heater, 24 is the heater switching relay 4, 2
5 is a fan motor for cooling electrical parts, 26 is a high-voltage capacitor, and 27 is a high-voltage diode.

Next, set the internal temperature in the oven to 180℃ for 20 minutes.
When heating for minutes, (1) First, press "Oven" on the keyboard 6, the relay 12 will operate, the oven lamp 13 will light up, and the display tube 5c corresponding to "Oven" on the display section 5 will correspond to the temperature scale. The display tube 5d lights up in red.

(2) Next, when the temperature control knob 8 is turned, the display tube 5d lights up in red up to "180".

(3) Then turn the time adjustment knob 7 to
will display “2000”.

(4) When the cooking start button 4 is pressed, the start signal switch 14, door monitor switch 15, oscillation stop devices 16 and 17 operate, and the relay 19 operates to energize the heater. relay 2 at the same time
4 switches the energization to the upper heater 22 and lower heater 23 every 20 seconds. In this embodiment, both the upper and lower heaters 22 and 23 are of 1KW. At this time, the display tube 5 corresponding to "oven" on the display section 5
c flashes and the time counts down from 2000 in 1 second increments. When the temperature of the heating chamber gradually rises to 100℃ or higher in the example, the red indicator tube 5d will be displayed.
The left edge of will begin to blink, and the blinking position will change as the temperature rises, and once the temperature reaches the set temperature, it will remain at that temperature.

As described above, in this embodiment, the color of the display tube 5d that displays the heating time and the time adjustment knob 7 are similar colors of blue-green and blue, and when a heater is used, such as in a grill or oven, the temperature can be adjusted. Display tube 5 to display
d and the temperature control knob 8 are made the same color, red, so that the relationship between the display contents and the operation section is clear, making it extremely easy to use. Furthermore, even when cooking continuously from high-frequency heating to heater heating, such as when cooking stews, the operation and display sections are distinguished by color, making it possible to accurately set time and temperature. Since you can see at a glance what is currently working while cooking, you can prevent cooking failures due to erroneous operations or misjudgments.

As described above, in the present invention, since it is easy to understand what is displayed on the display, the output state can be easily adjusted, cooking failures, etc. do not occur, and the product is extremely easy to use.
