位於玻璃頂板2上面之靜電體。因此，除了使用者用手指觸 碰接觸開關時以外，如第1(b)圖所示，當僅使用左燃燒器如 2〇來加熱鍋子20内的調理物時，有時會產生調理物的溢出物 21 ’且该〉並出物21會到達操作部6使右燃燒器4b用接觸開關 從off狀態切換至on狀態。 或者，也會發生使用者在調理時無意識地觸碰接觸開 關的情況，或者，因為小孩的惡作劇或玻璃頂板2上的掉落 13 1275751 物（抹布、食物等）或置於玻璃頂板2上之調理容器等使接觸 開關從off狀態切換至on狀態的情況。 因此，控制器30所具有之加熱控制機構31係如上所述 進行在違反使用者的意思將接觸開關從off狀態切換至〇11狀 5態時不會錯誤地接受對左燃燒器4a或右燃燒器4b之點火操 作的指示之處理。以下，依照第4圖〜第7圖的流程圖，針對 該處理作說明。另，雖然第4圖〜第7圖的流程圖主要是對左 燃燒器4a的處理，但對右燃燒器仆的處理也是相同的。 首先，第4圖之STEP1〜STEP6為用以辨識運轉開關1〇 10從〇 F F狀態切換至〇 N狀態再恢復至〇 F F狀態的情況之處 理。當將電源輸入爐具且控制器30開始作動時，則成為「待 機狀態」，且加熱控制機構31在第4圖之STEP1中等待運轉 開關10成為on狀態。 然後’當運轉開關10成為on狀態時，則前進至STEp2， 15且使2秒計時器與4秒計時器開始計時，並在接著的STEp3 與STEPSG所構成之迴路中，在STEI>3时確認運轉開關川 維持在〇 n狀態的情況並在s τ E p 3中等待2秒計時器的時刻 到達。 當ST肥中2秒計時器的時刻已到達時，即，運轉開關 20 10之0樣態持續2秒以上時，則前進至STEP4。STEp4、 STEP5為亮燈控制機構32所進行之處理，亮燈控制機構犯 係使無鎖顯示部16熄燈，同時使警報裝置18鳴響，藉此通 知使用者已接受運轉開關1〇之操作。 另一方面，當STEP30中運轉開關10不是〇n狀態時，可 14 1275751 判斷運轉開關10因雜訊等瞬間變成on狀態。因此，此時係 返回STEP1，且加熱控制機構31再次等待運轉開關1〇從0ff 狀態切換至on狀態。 加熱控制機構31在STEP6與STEP35所構成之迴路中， 5 在STEP35中確認4秒計時器的時刻到達並在STEP6中等待 運轉開關10成為off狀態。 當STEP6中運轉開關10成為off狀態時，即，在STEP1 中運轉開關10成為on狀態後經過4秒之前運轉開關1〇恢復 至off狀態時，則前進至STEP7，且加熱控制機構31使15分 10 鐘計時器開始計時。 另一方面，當STEP35中4秒計時器的時刻已到達時， 即，運轉開關10之on狀態持續4秒以上時，則前進至第7圖 之STEP80。第7圖為防設關機之處理，亮燈控制機構32在 STEP80中使無鎖顯示部16熄燈，並在STEP81中使加鎖顯示 15 部17亮燈，且在STEP82中使警報裝置18鳴響。 然後，加熱控制機構31在接著的STEP83中等待運轉開 關10成為on狀態。藉此，在藉由運轉開關1〇之操作解除防 设關機狀悲之鈾’會成為所有開關皆不能操作之防設關機 狀態。若在防設關機狀態下使用者碰到運轉開關1〇使運轉 20 開關10成為on狀態，則從STEP83前進至STEP84，且加熱控 制機構31使4秒計時器開始計時。 接著，加熱控制機構31在STEP85與STEP90所構成之迴 路中，在STEP90中確認運轉開關10是否為⑽狀態，並在 STEP85中等待4秒計時器的時刻到達。當STEP85中4秒計時 15 1275751 器的時刻已到達時，即，在防設關機狀態下使用者持續觸 碰運轉開關10，且運轉開關10成為ON狀態持續4秒以上 時，則前進至STEP86。在接著的STEP86中亮燈控制機構32 使加鎖顯示部17熄燈，且在STEP87中使警報裝置18鳴響， 5 並前進至第4圖之STEP1。藉此解除防設關機狀態。 當第4圖之STEP6中運轉開關1〇成為off狀態時，即，在 STEP1中運轉開關1〇成為〇n狀態後經過4秒之前，運轉開關 10成為off狀態時，則前進至STEP7，且控制器30使15分鐘 計時器開始計時。 10 接著，STEP8〜第5圖之STEP14為用以辨識點火準備開 關11 a從off狀態切換至on狀態再恢復至0ff狀態的情況之處 理。加熱控制機構31藉由STEP8與STEP40所構成之迴路， 在STEP40中確認15分鐘計時器的時刻是否到達，並在 STEP8中等待點火準備開關lla從off狀態切換至on狀態。然 15 後，當STEP8中點火準備開關lla成為on狀態時，則前進至 第5圖之STEP9。 另一方面，當STEP40中15分鐘計時器的時刻已到達 時，即，在STEP6中運轉開關10成為off狀態時起經過15分 鐘之前，點火準備開關lla未成為〇n狀態時，則前進至 20 STEP41，且控制器30使無鎖顯示部16熄燈，並在STEP0 中使警報裝置18鳴響，且返回STEP1成為「待機狀態」。藉 此，在使用者操作運轉開關10後，在經過15分鐘之前未進 行左燃燒器4a之點火操作時，則使爐具恢復至「待機狀 態」。 16 1275751 在第5圖之STEP9中，加熱控制機構^使丨秒計時器開 始計時’且藉由接著的STEP10與STEP50所構成之迴路，在 STEP50中確認點火準備開關lla是否為〇n狀態，並在 STEP10中等待1秒計時器的時刻到達。然後，當stepio中1 5秒計時器的時刻已到達時，即，點火準備開關lla成為on狀 態持續1秒以上時，則前進至STEP11。 另一方面，當STEP50中1秒計時器的時刻已到達時， 即，點火準備開關11 a成為on狀態不到1秒時，可判斷點火 準備開關lla因雜訊等瞬間變成on狀態。因此，此時係返回 10第4圖之STEP7，且加熱控制機構31再次等待點火準備開關 lla從off狀態切換至on狀態。 STEP11〜STEP12為亮燈控制機構32所進行之處理，亮 燈控制機構32係使點火準備顯示部14a媳燈，且在STEP12 中使警報裝置18鳴響。然後，加熱控制機構31在STEP13中 15 使2秒計時器開始計時，且藉由接著的STEP14與STEP55所 構成之迴路，在STEP14中等待點火準備開關lla成為off狀 態。 當STEP14中點火準備開關lla成為off狀態時，即，點 火準備開關lla成為on狀態1秒後，點火準備開關lla在2秒 20 之内從on狀態恢復至off狀態時，則前進至STEP15，且加熱 控制機構31使10秒計時器開始計時。 另一方面，當STEP55中2秒計時器的時刻已到達時， 即，點火準備開關lla成為on狀態1秒後，點火準備開關Ha 再繼續成為on狀態2秒，則前進至STEP56。然後，控制器 17 1275751 30在STEP56中使點火準備顯示部14a熄燈，且在STEP57中 使警報裝置18鳴響，並返回第4圖之STEP7。藉此，當因溢 出的湯汁等使點火準備開關11a成為維持在on狀態的狀況 時’可禁止STEP15以後的處理，而不執行左燃燒器4a之點 5 火處理。 接著，STEP15〜第6圖之STEP19為用以辨識火力UP開關 l：3a從off狀態切換至on狀態再恢復至off狀態的情況之處 理。加熱控制機構31在STEP15中使10秒計時器開始計時， 且前進至第6圖之STEP16，並藉由STEP16與STEP60所構成 10 之迴路，在STEP60中確認1秒計時器的時刻是否到達，並 在S TEP16中等待火力UP開關13 a從off狀態切換至on狀態。 當STEP16中火力UP開關13a成為on狀態時，即，在點 火準備開關11a成為off狀態後1〇秒之内火力UP開關13a切 換至on狀態時，則前進至STEP17。STEP17與STEP18為亮 15 燈控制機構32所進行之處理，亮燈控制機構32在STEP17中 使火力位準顯示部15a以位準4亮燈，且在STEP18中使警報 裝置18鳴響，並前進至STEP19。

Further, when the ignition preparation switch 丨la or the operation opening is operated in the combustion of the left burner 4a, the left burner 4a is executed. 1275751 Similarly, in order to instruct the right burner 4b to operate, an ignition quasi-injury switch 1 ib (corresponding to the actuating preparation switch of the present invention) which can be set to allow the ignition preparation state of the left burner 4b is further provided. 5 stages (level 1 Level 5) switching the fire power DOWN switch 12b of the left burner 4b and the fire power up switch 5 13b (corresponding to the heating amount UP switch of the present invention), and when the left burner is in the ignition ready state and the left burner 4b The ignition preparation display portion 14b for lighting and the fire level display portion 15b for displaying the fire power setting of the left burner 4b. When the right burner 4b is in the ignition preparation state, the fire power 10 UP switch 13b is operated. At the same time, the right burner igniting process is executed. Further, when the ignition preparation switch 丨 lb or the operation switch 操作 is operated in the combustion of the right burner 4b, the flame extinguishing process of the right burner 4b is executed. The processing unit 6 further includes a lock-free display unit 16 that lights up when in the "operating state", and a so-called anti-setting that all switches cannot be operated after the operation switch 1 is operated for a predetermined time (for example, *15 seconds) or more. The lock display portion 17 is turned on when the power is off. " Here, each switch of the processing unit 6 is a static capacitance sensor disposed inside the glass top plate 2 and printed on the glass opposite to the electrostatic capacitance sensor. Surface of the top plate 2 And a portion of the printed portion of the contact point of each switch is formed by a contactless contact type. Then, when the electrostatic body is placed on the printed portion (the surface portion of the glass top plate 2 facing the electrostatic capacitance sensor) When the electrostatic capacitance sensor detects the electrostatic body, and the connection is turned into a fine state (equivalent to the measurement of the month of the month). On the other hand, when the electrostatic body is not placed in the printed portion ^ The static capacitance sensor does not detect the electrostatic body, and the contact switch is in the off state of 11 1275751 (corresponding to the non-detection state of the present invention). Further, each display portion of the operation unit 6 is provided on the glass top plate 2 The LED inside is printed on a printed portion printed on the surface portion of the glass top plate 2 facing the LED. Further, when the LED is turned on, the display unit is turned on, and when the LED is turned off, the display unit is in a dark state. Further, the printed portion may not be provided on the surface portion of the glass top plate 2, and the display portion may be constituted only by a lighting mechanism such as an LED provided inside the glass top plate 2. φ and 'the fire level display unit Ua is the light level of the left part of the light-emitting part of the left side of the bar display. The number of lights on the left side of the bar display indicates the fire level of the left-burning device. 1~ level 5). For example, when the fire level of the left burner 4a is 1, only the lighting portion of the left end of the bar display is illuminated, and when the fire level of the left burner 4a is 5, the bar is displayed with 5 lighting portions. All lights up. Similarly, the fire level display portion 15b also indicates the fire level of the right 15 burner servant by the number of lights on the left side of the bar display formed by the five illuminated portions shown in the figure (level position 丨~ Level 5). φ Next, 'Tea Photo 3' is provided in the stove body 1 with a controller 30 for controlling the overall operation of the stove, and the switches of the operation unit 6 (the operation switch 10, the ignition preparation switches 11a, 11b, and the fire power D) The detection signals of the operating states (〇n/〇ff) of the 〇WN switches 12a, 12b, and the thermal power UP switches 13a, 13b) are input to the controller 30. In addition, the operation of the following mechanism is controlled by the control signal rotated from the controller 30. The fuel gas is supplied to the furnace body 丨 or the supplied gas M4G is shut off, and the fuel gas is supplied to the left combustion. The left burner burner valve 41a for shutting off the supply, and the left burner heat regulating valve 42a for changing the supply flow rate of the fuel gas supply 12 1275751 to the left burner 4a (corresponding to the heating amount changing mechanism of the present invention) Applying a high voltage to the ignition electrode (not shown) of the left burner 4a to generate a spark discharge for the left burner ignition > 43a for switching the fuel gas supply to the right burner or blocking the supply 5 The burner on/off valve 41b, the right burner thermal power adjustment valve 42b for changing the supply flow rate of the fuel gas to the right burner 4b (corresponding to the heating change mechanism of the present month), and applying the south voltage to the right burner An ignition electrode (not shown) for generating a spark discharge to the right burner igniter 4; Further, each display unit (ignition preparation display units 14a and 14b, the fire level display units 15a and 15b, and the lockless display unit 16) provided in the operation unit 6 is controlled by a control signal output from the controller 30. The lighting/dark light of the display portion 17) and the on/off of the alarm device 18 are locked. Further, the control state % includes a notification of the heating control means 31 for controlling the left burner 4a and the right burner 4b, and the control and alarm means 18 for turning on/off the lights of the display portions 15 of the operation unit 6. The lighting control mechanism 32 is as follows. As described above, the contact switch provided in the operation unit 6 can detect the presence or absence of an electrostatic body on the glass top plate 2. Therefore, when the user touches the contact switch with a finger, as shown in FIG. 1(b), when only the left burner such as 2 〇 is used to heat the conditioning material in the pot 20, the conditioning material sometimes occurs. The spill 21' and the exit 21 reach the operation unit 6 to switch the right burner 4b from the off state to the on state with the contact switch. Alternatively, there may be a case where the user unconsciously touches the contact switch during conditioning, or because the child's mischief or the falling of the glass top plate 2 13 1275751 (rag, food, etc.) or placed on the glass top plate 2 A condition in which the container or the like is switched to the on state from the off state to the on state. Therefore, the heating control mechanism 31 included in the controller 30 does not erroneously accept the left burner 4a or the right combustion when the contact switch is switched from the off state to the 〇11 state in violation of the user's intention as described above. The processing of the indication of the ignition operation of the device 4b. Hereinafter, the processing will be described in accordance with the flowcharts of Figs. 4 to 7 . Further, although the flowcharts of Figs. 4 to 7 are mainly the processing of the left burner 4a, the processing for the right burner is the same. First, STEP1 to STEP6 in Fig. 4 are used to recognize that the operation switch 1 〇 10 is switched from the 〇 F F state to the 〇 N state and then returned to the 〇 F F state. When the power is input to the oven and the controller 30 starts to operate, the "standby state" is reached, and the heating control unit 31 waits for the operation of the switch 10 in the STEP 1 of Fig. 4 to be in the on state. Then, when the operation switch 10 is in the on state, the process proceeds to STEp2, 15 and the 2-second timer and the 4-second timer are started, and is confirmed in the circuit formed by the subsequent STEp3 and STEPSG at STEI>3. The operation switch is maintained in the 〇n state and arrives at the time of waiting for the 2-second timer in s τ E p 3 . When the time of the 2-second timer in the ST fat has arrived, that is, when the 0 state of the operation switch 20 10 continues for 2 seconds or more, the process proceeds to STEP 4. STEp4 and STEP5 are processes performed by the lighting control unit 32. The lighting control unit activates the lock-free display unit 16 to turn off the light, and causes the alarm device 18 to sound, thereby notifying the user that the operation of the operation switch 1 is accepted. On the other hand, when the operation switch 10 in the STEP 30 is not in the 〇n state, it is determined that the operation switch 10 is turned to the on state due to noise or the like. Therefore, at this time, the process returns to STEP 1, and the heating control mechanism 31 waits again for the operation switch 1 to switch from the 0 ff state to the on state. In the circuit formed by STEP 6 and STEP 35, the heating control unit 31 confirms that the time of the four-second timer has arrived in STEP 35 and waits for the operation switch 10 to be in the off state in STEP 6. When the operation switch 10 in the STEP 6 is in the off state, that is, when the operation switch 1 is returned to the off state 4 seconds before the operation switch 10 is turned to the ON state in STEP 1, the process proceeds to STEP 7 and the heating control mechanism 31 makes 15 points. The 10-clock timer starts counting. On the other hand, when the time of the 4-second timer in STEP 35 has arrived, that is, when the on-state of the operation switch 10 continues for 4 seconds or longer, the process proceeds to STEP 80 of Fig. 7. Fig. 7 is a process for preventing shutdown, the lighting control unit 32 turns off the lock display unit 16 in STEP 80, and causes the lock display 15 portion 17 to light in STEP 81, and causes the alarm device 18 to sound in STEP 82. . Then, the heating control unit 31 waits for the operation switch 10 to be in the on state in the next STEP 83. Therefore, the uranium which is turned off by the operation of the operation switch 1 会 will become a shutdown state in which all switches cannot be operated. When the user touches the operation switch 1 in the shutdown state and the operation 20 switch 10 is turned on, the process proceeds from STEP 83 to STEP 84, and the heating control unit 31 starts the timer for 4 seconds. Next, in the circuit constituted by STEP85 and STEP90, the heating control unit 31 confirms whether or not the operation switch 10 is in the (10) state in STEP 90, and waits for the time of the 4-second timer to arrive in STEP85. When the time of the 12-second timer 15 1275751 has arrived in STEP85, that is, when the user continues to touch the operation switch 10 while the power-off state is off, and the operation switch 10 is turned ON for 4 seconds or more, the process proceeds to STEP86. In the next STEP 86, the lighting control unit 32 turns off the lock display unit 17, and in step 87, the alarm device 18 is sounded, and proceeds to STEP 1 in Fig. 4. This disables the shutdown state. When the operation switch 1 〇 in the STEP 6 of FIG. 4 is in the off state, that is, when the operation switch 10 is turned off 4 seconds after the operation of the switch 1 〇 in the STEP 1 state, the process proceeds to STEP 7 and the control is performed. The timer 30 causes the 15-minute timer to start timing. 10 Next, STEP 14 of STEP 8 to Figure 5 is a case for identifying that the ignition preparation switch 11 a is switched from the off state to the on state and then to the 0 ff state. The heating control unit 31 confirms whether or not the time of the 15-minute timer has arrived in STEP 40 by the circuit formed by STEP 8 and STEP 40, and waits for the ignition preparation switch 11a to switch from the off state to the on state in STEP 8. After that, when the ignition preparation switch 11a in the STEP 8 is turned on, the process proceeds to STEP 9 in Fig. 5. On the other hand, when the time of the 15-minute timer in STEP 40 has arrived, that is, when the ignition preparation switch 11a does not become the 〇n state 15 minutes after the operation switch 10 is turned off in STEP 6, the process proceeds to 20 In STEP 41, the controller 30 turns off the lock display unit 16 and causes the alarm device 18 to sound in STEP0, and returns to STEP 1 to be in the "standby state". Therefore, after the user operates the operation switch 10, the ignition of the left burner 4a is not performed until 15 minutes have elapsed, and the stove is returned to the "standby state". 16 1275751 In STEP9 of Fig. 5, the heating control mechanism ^ causes the leap second timer to start timing' and confirms whether the ignition preparation switch 11a is in the 〇n state by the loop formed by the subsequent STEP 10 and STEP 50, and The time at which the 1 second timer waits in STEP 10 arrives. Then, when the time of the 15-second timer in stepio has arrived, that is, when the ignition preparation switch 11a is in the on state for 1 second or longer, the process proceeds to STEP 11. On the other hand, when the time of the one-second timer in the STEP 50 has arrived, that is, when the ignition preparation switch 11a is turned on for less than one second, it can be judged that the ignition preparation switch 11a is turned to the on state due to noise or the like. Therefore, at this time, STEP 7 of Fig. 4 is returned, and the heating control mechanism 31 waits again for the ignition preparation switch 11a to switch from the off state to the on state. STEP 11 to STEP 12 are processes performed by the lighting control unit 32, and the lighting control unit 32 causes the ignition preparation display unit 14a to turn on the light, and the alarm device 18 is sounded in STEP 12. Then, the heating control means 31 starts the counting of the two-second timer in STEP 13, and waits for the ignition preparation switch 11a to be in the off state in STEP 14 by the circuit formed by the subsequent STEP 14 and STEP 55. When the ignition preparation switch 11a is in the off state in STEP 14, that is, after the ignition preparation switch 11a is in the on state for 1 second, the ignition preparation switch 11a is returned from the on state to the off state within 2 seconds 20, and then proceeds to STEP 15, and The heating control mechanism 31 causes the 10-second timer to start counting. On the other hand, when the timing of the two-second timer has arrived in STEP 55, that is, after the ignition preparation switch 11a is turned on for one second, the ignition preparation switch Ha continues to be in the on state for two seconds, and proceeds to STEP56. Then, the controller 17 1275751 30 turns off the ignition preparation display portion 14a in STEP 56, and causes the alarm device 18 to sound in STEP 57, and returns to STEP 7 in Fig. 4. As a result, when the ignition preparation switch 11a is maintained in the on state due to the overflow of the soup or the like, the processing after STEP 15 can be prohibited, and the point 5 fire processing of the left burner 4a is not performed. Next, STEP 19 of STEP 15 to Figure 6 is a case for identifying that the fire power UP switch l: 3a is switched from the off state to the on state and then to the off state. The heating control unit 31 starts the counting of the 10-second timer in STEP 15, and proceeds to STEP 16 of Fig. 6, and confirms whether the time of the one-second timer has arrived in STEP 60 by the loop of 10 formed by STEP 16 and STEP 60. Waiting for the firepower UP switch 13a to switch from the off state to the on state in the S TEP16. When the firepower UP switch 13a in the STEP 16 is in the on state, that is, when the fire power UP switch 13a is switched to the on state within 1 second after the ignition preparation switch 11a is turned off, the process proceeds to STEP 17. STEP 17 and STEP 18 are processed by the light 15 lamp control unit 32, and the lighting control unit 32 turns on the fire level display unit 15a at the level 4 in STEP 17, and causes the alarm device 18 to sound in STEP 18 and advances. To STEP19. Here, when the fire power UP switch 1; 3a in the STEP 16 is in the on state, the ignition process of the left burner 4a executed in the STEP 20 described later is performed first, and the fire level display portion 15a is turned on in the STEP STEP 17 This informs the user that the ignition instruction has been accepted. On the other hand, when the time of the 10-second timer in the STEP 60 has arrived, that is, even if the ignition-up switch 11a is turned off after 1 second, and the firepower UP switch 13a is not switched to the 〇n state, the process proceeds to STEP61. . 18 1275751 STEP 61 to STEP 62 are processes performed by the lighting control unit 32. The lighting control unit 32 turns off the ignition preparation display unit Ma in STEP 61, and causes the alarm device 18 to sound in STEP 62, and returns to Fig. 4. By this, the heating control mechanism 31 waits again for the ignition preparation switch (1) to switch from the 〇ff state to the on state. The heating control unit 31 confirms whether or not the 10-second timer has arrived at STEP 65 by the loop formed by STEP 19 and STEP 65, and waits for the fire power UP switch 13a to return to the 0 ff state in STEP 19. Then, when the dedicated fire power UP switch 13a in STEP 19 returns to the 0 ff state, it proceeds to 10 STEP 20, and the igniter 43a is actuated by the heating control mechanism 31 to open the gas source valve 4 in a state where the ignition electrode generates a spark discharge. The left burner open/close valve 41a is set to the left burner fire regulating valve 42a at the fire level 4 to perform the ignition processing of the left burner 4a (corresponding to the start of the operation of the heating mechanism of the present invention). 15 On the other hand, when the time of the 10-second timer in STEP 65 has arrived, that is, within 1 second after the ignition preparation switch 11a is in the 〇n state, the fire-up switch 13a is switched from the off state to the on state, and is restored. When the status is set, proceed to STEP66. STEP 66 and STEP 68 are processes performed by the lighting control unit 32. The lighting control unit 32 turns off the ignition preparation display unit 20 14 & in STEP 66, and turns off the fire level display unit 15a in STEP 67, and in STEP 68, The alarm device 18 is sounded and returns to STEP 7 of Fig. 4. As described above, after the operation switch 1 〇 is switched to the off state -> on state - 0 ff state, the ignition control switch 31 is switched to the off state - on state - 0 ff state, and the fire power UP switch is turned off in the ignition ready switch 11 & When 13a is switched to off 19 1275751 state-cm state off state, the ignition process of the left burner 4a is performed. Therefore, when the user unconsciously touches the operation portion 6, or because the child's mischief, the soup spilled from the conditioner, etc., only one of the operation switch 1〇, the ignition preparation switch 1 la, and the fire power UP switch 13a is from 〇ff When the state is switched to the on state, or when the state is restored from the 0n state to the 〇ff state, the ignition process of the left burner 4a is executed. Further, even after the "operating state" is reached, when one of the ignition preparation switch ua and the thermal power UP switch 13a is switched from the 〇 ff state to the 〇 n state, or when the on state is returned to the off state, the left burner is not executed. As for the point 10 fire treatment. Further, in the present embodiment, the stove having the gas burners 4a, 4b is shown as the heating means of the present invention, but the present invention is also applicable to a cooker having a heating mechanism of another type such as an electric heater. Further, in the present embodiment, a contact device using a capacitive contact type open-close 15 is used as the contact switch of the present invention, but the type of the contact switch is not limited thereto, and even a light-emitting portion/light-receiving portion having infrared rays is used. The present invention can also be applied to a stove of a mechanical contact type contact switch such as an optical switch or a contact switch. Further, in the present invention, although a stove having 20 glass top plates 2 made of ray-resistant glass is used as the top plate of the present invention, depending on the type of the contact switch, the top plate having other materials such as stainless steel is used. The invention is also applicable. In addition, in the present state, although the furnace having the burner of 2_ is the heating mechanism, the stove having i heating mechanisms or the heating device having the heating mechanism of 20 1275751 or more is also The invention is applicable. Further, in the present embodiment, although the oven having the operation switch is displayed, the effect of the present invention can be obtained without the stove for operating the switch. Further, in the present embodiment, the firepower UP switches 13a and 13b are used as a switch for instructing the left burners 4a and 4b to ignite, thereby reducing the number of contact switches in the operation unit 6, but it is also possible The switch for instructing the left burners 4a, 4b to ignite and the firepower UP switches 13a, 13b are individually provided. Further, in the present embodiment, in the flowcharts of FIGS. 4 to 6, the switch 10, the ignition preparation switch 11a, and the heating power switch 13a are operated, and after switching from the Off state to the On state, When returning from the on state to the off state, the process proceeds to the next STEP, but the effect of the present invention can be obtained by proceeding to the next STEP when switching from the off state to the on state.
