(See Figure 2)

The operation of the gas table A will be described with reference to FIG.

For example, when the user presses the ignition / extinguishing button 201 of the left stove 2 (in the elapsed time 71), the main valve 208 is opened and at the same time the switch 201a is turned on. ), The combustion control unit 6 energizes the safety valve 203 for a predetermined time and keeps the valve open, while energizing the ignition electrode 22 to ignite the left furnace 2 to start combustion. do.

In the thermocouple 23, the output voltage gradually rises due to the combustion flame 20, and the output voltage becomes more than the ignition level (2.5 mV) (in the elapsed time 72), and the combustion control unit 6 The energization of the safety valve 203 is continued even after a predetermined time has elapsed and the energization to the ignition electrode 22 is stopped while energizing the LED 52 to emit red light.

Then, among the keys 414, 415, 416, 417, 418, and 419 for selecting a cooking mode, for example, when the frying cooking mode key 414 is pressed, the LED 421 (digital display) displays the cooking temperature when the frying cooking mode is used. Then, when the setting key 412 is pressed to lower the cooking temperature for the displayed temperature and the setting key 413 is pressed to increase, the changed cooking temperature is displayed on the 7-segment green LED 411. .

Thereafter, when the ignition and fire extinguishing button 201 is pressed again to extinguish the fire, the main valve 208 is closed and the switch 201a is turned off, and the safety valve 203 is not energized. At the same time as (2) is extinguished, the LED 52 is also in a non-energized state and the LED 52 is turned off. {Elapsed time 75}

In addition, when the M burner 21 of the left side furnace 2 is turned off (in the elapsed time 73) by the wind or the shaking of the flame, the output voltage of the thermocouple 23 falls below the ignition level (2.5 mV). At the point of time (at elapsed time 74), the combustion control unit 6 stops supplying power to the safety valve 203, stops gas supply to the M burner 21, and simultaneously changes the LED 52 to a blinking display. To inform the user of the occurrence of an abnormal condition.

In addition, in the above description, the cooking mode is selected after the operation of the ignition / fire extinguishing button 201, but the selection of the cooking mode and the setting key are pressed to set the cooking mode, the cooking temperature, and the like. It is also possible to start combustion with). In this case, for example, by pressing the fry cooking mode key 414, the LED 421 is turned on, and then the cooking temperature is set by the key 412 or 413 to be displayed on the 7-segment green LED 411. Then, the ignition operation is performed to cause the LED 52 to move.

Next, the advantages of the present embodiment will be described.

(A) In the right furnace 1 and the left furnace 2, the fire power is weak and the combustion flame 10, as in the case where cooking vessels such as pots 17 and 27 are placed on the sambas 16 and 26, respectively. Although it is difficult to visually confirm 20) directly, the gas table figure 5 drawn in correspondence with the arrangement positions of the right furnace 1 and the left furnace 2 shows immediately which furnace is burning. have. Moreover, in the roasting chamber 3, although the baking chamber burner 31 of the porous combustion type is arrange | positioned by the parent in the roasting chamber, even if it is difficult to visually confirm a combustion flame, when looking at the gas table figure 5, the roasting chamber ( It is easy to know whether or not 3) is burning.

(B) When the output voltage values of the thermocouples 13, 23, and 33 generating electromotive force by the combustion flame are above the ignition level, the LEDs 51, 52, and 53 are configured to emit red light. 11) The M burner 21 can clearly know whether or not the roasting chamber burner 31 is actually in a combustion state.

(C) The lighting of the LEDs (eg, LED 52) in the gas table graphic 5 is a test of the elapsed time 72 at which the ignition level is reached, but the LED 52 is extinguished when the extinguishing operation is performed. Since the silver switch 201a is the elapsed time 75 that has been opened, the light is turned off at the same time as extinguishing, so that no user is mistaken.

(D) The gas table figure 5 is drawn so that the right side furnace 1, the left side furnace 2, and the roasting chamber 3 are easily located where they are located with respect to the gas table A. It is easy to know which LEDs 51, 52, and 53 mean. In addition, the keys 412 and 413 for setting the cooking temperature or the cooking time are arranged in the same frame as the green LED 411 of the seven-segment displayed digitally, which makes it easy to judge.

The present invention includes the following embodiments in addition to the above examples.

(1) The light emission intensity at the corresponding position of the figure corresponding to the combustion burner may be increased in proportion to the intensity of the thermal power. In addition, the light emission intensity may be changed in order to make it look realistic.

(2) When the switches 101a, 201a, 301a are turned on, the LEDs 51, 52, 53 may emit light, and the state of light emission may be changed when the output voltage reaches the ignition level.

(3) When the LEDs 51, 52, 53 are displayed in two colors, red and green, and the ignition / extinguishing buttons 101, 201, 103 are pressed and the switches 101a, 201a, 301a are turned on, the corresponding LEDs 51, 52, 53, 52 are displayed. And (53) may be emitted in green and switched to red emission when the ignition level is reached. In this case, when the burners are turned off during combustion, the LEDs 51, 52 and 53 switch to green light emission.

(4) The gas table graphic 5 may be displayed not only in printing but also in liquid crystal or LED graphics.

(5) The LEDs 51, 52, and 53 indicating the burner's combustion can be saved by flashing when the output voltage reaches the ignition level (e.g., turning on for 0.5 seconds-turning off for 1 second). It is especially advantageous when the battery is used as the power supply. In this case, the ignition confirmation can be more easily known by only lengthening the initial lighting time (for example, 5 seconds) during the ignition operation (the switches 101a, 201a, and 301a on).

(6) Combustion control may be performed by selecting a cooking mode by operating panel 4 of burner to be used by using two-color (red, green) display type LED.

When the select key for selecting the cooking mode is pressed, the LED in the gas table graphic 5 emits green light. Afterwards, the LED that emits green light will be moved in the order of LED (52) → LED (51) → LED (53) in every pressing operation. Therefore, set the cooking time of the burner by fixing it to the LED of the burner to be used. Press the SET key to select. After that, when the output voltage reaches the ignition level by the ignition operation, the LEDs 51, 52, and 53 in the gas table graphic 5 are switched to red.

That is, when the cooking mode is selected and the burner (for example, the H burner 11) corresponding to the LED emitting green light is ignited, the LED emitting green light (for example, LED 51) reaches the ignition level. At one point, the green color is red, and the light is emitted.

When only the burner (for example, M burner 21) for which the cooking mode is selected is lit, the corresponding LED (for example, LED 52) when the burner (M burner 21) for which the cooking mode is selected reaches the ignition level. ] Emits red light, and the LED (e.g., LED 51) corresponding to another burner (e.g., H burner 11) maintains the green emission state. In addition, the burner which is being burned, that is, the LED which is already lit in red, does not change to green even when the selector key is pressed.

(7) In order to easily select a cooking mode, two color (red and green) LEDs are formed at the upper left of each selector and the "cancel" key. In this case, the switch (e.g., switch 101a) is turned on by the ignition operation of the burner (e.g. H burner 11) to be used. When the LED is emitting green (e.g., LED 425 for timer cut, LED 423 for roasting, LED 424 for water breaking, LED for canceling), and then pressing the select key to select the mode, the corresponding The LED may be switched to red light emission.

(8) An LED may be provided on the rear surface of the operation panel 4 at the “hour, minute, degree” position in the vicinity of the green LED 411 of the seven segments to emit light. In this case, when the continuous cooking mode key 415 for setting the time or the timer cut mode key 418 is pressed, the tempura cooking mode key for setting the temperature is set so that the LED at the “hour, minute” position is emitted. In the case of pressing 414), the LED of the "degree" position is made to emit light, and in the selected cooking mode, it is displayed clearly what kind of setting is necessary, so that the convenience of use is improved.
