Abstract

PURPOSE:To prevent mistakes in the operation steps by providing display lamps close to the operation sections for temperature setting arranged on the operation panel, time setting and start of cooking, and flickering successively the display lamps by selectively operating the cooking function selection switches. CONSTITUTION:After a food is placed in a heating room 2, its door 3 is closed and either one of cooking function switches 9 is pressed. Supposing a selected cooking function is 'oven', firstly a display lamp 13 flickers. Next, if the temperature in the store room is set by pushing a temperature setting button 10, the display lamp 13 is put off and further a display lamp 14 for time setting flickers. Here, when a time setting knob 11 is rotated to set time, the display lamp 14 is put off and a display lamp 15 flickers. Next, when a start of cooking button is pressed, the display lamp 15 is put off and cooking is started. If automatic cooking is selected, start of cooking button 12 is directly operated. A microcomputer 16 thus makes display lamps flicker whichever cooking function may be selected and indicates the operation steps. Mistake in operation is therefore prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a high-frequency heating device that allows a plurality of cooking functions to be selected.

[Conventional technology]

FIG. 4 is a diagram showing a conventional high-frequency heating device equipped with a heater 7. In the figure, 1 is a main body, 2 is a heating chamber, and 3
is a door that covers the entire surface of the heating chamber, 4 is a high-frequency oscillator, 5 is a heater placed above and below heating chamber 2, 6 is a turntable on which food is placed, and 7 is an operation panel provided on the front of main body 1. , a time or temperature display section 8, a cooking function selection switch 9, a push button 10 for setting the temperature, a time setting knob 11 for setting the cooking time, and a cooking start button 12 for starting cooking. It is set up.

The conventional high-frequency heating device is configured as described above, and if, for example, the oven function is selected from the cooking function selection switch S, the temperature setting button 10 is first pressed several times to set the predetermined temperature, and then the time setting knob 11 is turned. to set the cooking time.

At this time, the temperature or time is displayed numerically on the display.

By pressing the cooking start button 12 in this state, the heater 5 is energized, and the heating chamber 2 is maintained at a predetermined temperature while the heater 5 is energized for a set period of time from ON to 0 FFL, and cooking is performed.

Next, if you select, for example, the range from the function selection switch 9, the oven does not use the cooker 5, so there is no need to set the temperature, and after turning the time setting knob 11 and setting the cooking time, cooking starts. When the button 12 is pressed, the high frequency oscillator 4 is activated and cooking is performed. - When automatic cooking is selected with the function selection switch 9, the sensor detects the cooking completion and the control circuit including the microcomputer automatically operates the high frequency oscillator 4, so the cooking start button 12 is pressed. Just press it to start cooking.

Furthermore, if the door 3 is opened during all cooking operations, the cooking operation is started by temporarily stopping the cooking operation, closing the door 3, and pressing the cooking start button 12.

[Problem that the invention seeks to solve]

In the conventional high-frequency heating device as described above, for example, after pressing the cooking function selection button 10, the temperature setting button 10. Alternatively, the procedure to start cooking differs depending on the cooking function, such as the need to set one or more of the time setting knob 11 or the cooking start button 12 in order, making the procedure complicated and difficult for users to understand. The problem was that it was extremely difficult to handle.

This invention has been made to solve the above-mentioned problems, and aims to provide a high-frequency heating device that can prevent malfunctions by instructing operating procedures on an operation panel.

[Means for solving problems]

The high-frequency heating device according to the invention of Party B is provided with an indicator lamp near each operation section for temperature setting, time setting, and cooking start arranged on the operation panel, and the indicator lamp can be activated by selecting the cooking function selection switch. It is designed to blink sequentially.

[Effect]

The display lamp according to the present invention sequentially blinks the operation parts to be operated corresponding to the cooking function according to the operation procedure.

〔Example〕

FIG. 1 is a perspective view showing an embodiment of the present invention.
12 is exactly the same as the conventional device described above.

13 is an indicator lamp installed on the operation panel 7 near the temperature setting button 10; 14 is an indicator lamp installed on the operation panel 7 near the time setting knob i:11; 7 may be provided.

FIG. 2 is a circuit diagram, in which the cooking function selection switch 9 is connected to the input 6[1 of the microcomputer 16. Further, the microcomputer 1B simultaneously controls the high frequency oscillation W4 and the operation of the heater 5 via the control relay 17.

The operation of the high-frequency heating device configured as described above will be explained using the flowchart of FIG. 3.

After placing the food in the heating chamber 2, the door 3 is closed and one of the cooking function selection switches 9 is pressed.

If the cooking function selected here is oven,
In this case, it is necessary to set the temperature, so first set the indicator lamp 1.
3 blinks.

When the temperature inside the refrigerator is set by pressing the temperature setting button 10, the display lamp 13 turns off, and then the display lamp 14 blinks because it is necessary to set the time.Now, turn the time setting knob 11 to set the time. Then, the display lamp 14 goes out,
Next, when the display lamp 15 flashes, press the button 1 to start cooking.
When 2 is pressed, the display lamp 15 turns off and cooking begins.

If the door 2 is opened during cooking, the cooking will be temporarily stopped and the display lamp 15 corresponding to the cooking start button 12 will blink, and the cooking can be restarted by pressing the cooking start button 12.

Although the explanation has been given using an oven as an example, for example, if you select the microwave as the cooking function, you only need to set the time and then operate the cooking start switch 12.
If you select the 111rM process, you can directly operate the cooking start button 12, so the microcomputer 16
The display lamp corresponding to the operation section required by the user is blinked according to the operation procedure, and the user is instructed on the operation procedure.

Therefore, if the user operates the operation section corresponding to each flashing indicator lamp in sequence, cooking will finally begin, and each time the user operates the operation while looking at the attached cooking instructions and operation manual. This eliminates the need for a single high-frequency heating device with multiple functions, making it extremely easy to handle.

〔Effect of the invention〕

As described above, according to the present invention, no matter which cooking function is selected, the display lamp instructs the operation procedure, which eliminates erroneous operations and makes handling extremely easy. .
