  In the grill 3, a temperature rise rate (referred to as a temperature rise gradient) that changes in accordance with a difference in the mounting state of the object to be heated 34 in the grill 33 in the initial stage after the heating by the grill burner 32 is started. Temperature detection means is provided, and the control unit obtains the temperature rise gradient based on the detection information of the temperature detection means, and the temperature rise gradient obtained in the determination information calculation process Based on this information, the total heating time from the execution of the determination information calculation process to the end of heating of the article to be heated 34 is obtained. The total heating time applies a predetermined value or obtains a value from a predetermined calculation formula according to the type of cooking menu and the placement state of the article to be heated 34.

  As a temperature detecting means, as shown in FIG. 2, the rear end portion of a partition plate 39 that divides the exhaust passage 38 vertically from the vicinity of the rear end portion of the grill 33 of the exhaust opening to the middle portion of the exhaust passage 38. An upper temperature sensor 35 is provided on the upper side, and a lower temperature sensor 36 is provided in the vicinity of the exhaust opening on the bottom surface of the lower exhaust passage (that is, in the vicinity of the opening serving as the inlet of the lower exhaust passage). is there. The upper temperature sensor 35 is provided at the position where the combustion exhaust gas of the upper burner 32a and the pair of left and right lower burners 32b flows, so that the elapsed time for determining the heat capacity from the start of heating until the temperature rises to the set determination temperature. The position of the lower temperature sensor 36 is different depending on the magnitude of the thermal load of the object to be heated 34, and the position where the lower temperature sensor 36 is provided is different in the mounting state of the object to be heated 34 mounted on the grill 33. The temperature rise gradient differs depending on the location. When the amount of the object to be heated 34 placed on the grill 33 is small, as shown in FIG. 2, the combustion exhaust gas of the lower burner passes through the lower side of the grill and the upper side of the grill. As the flow rate flowing through the upper exhaust passage (upper side of the partition plate 39) increases and the amount of the object to be heated 34 placed on the grill 33 increases, the object to be heated 34 is blocked as shown in FIG. Accordingly, the amount of combustion exhaust gas of the lower burner 32b passing above the grill 33 is reduced, and the flow rate flowing through the lower exhaust passage is small, and the upper temperature sensor 35 and the lower temperature sensor 36 detect accordingly. The temperature will be different. In the control, it is possible to arbitrarily select which one of the detected temperatures of the upper temperature sensor 35 and the lower temperature sensor 36 or both of them is used (for example, an average value is taken).

  When the temperature increase gradient is small, that is, when the temperature increase value at a predetermined time is small, it can be determined that a large object to be heated 34 having a large heat capacity is placed on the grill 33 of the grill 3. The total heating time TT is calculated and set in accordance with the gradient, and when the temperature rise gradient is large, that is, when the temperature rise value for a predetermined time is large, the grill 33 of the grill 3 has a small heat capacity and a small heat to be heated. Since it can be determined that the object 34 is placed, the total heating time TT is calculated and set in a short time according to the temperature rise gradient. The total heating time TT is calculated by substituting a value corresponding to the temperature increase gradient in advance or by substituting the value of the temperature increase gradient into a predetermined calculation formula.

  The elapsed time T1 from the time when heating by the grill burner 32 is started to the time when the total heating time TT is calculated and set is measured.

  Then, the remaining heating time T2 from the time when the total heating time TT is calculated and set until the heating of the article to be heated 34 is obtained as T2 = TT−T1, and T2 is displayed as a grill timer display (timer in FIG. 6). It is displayed on the upper side of the switch 62.

  After displaying T2 on the grill timer display unit, the remaining heating time T2 displayed on the grill timer display unit is counted down over time, and when the display on the grill timer display unit becomes zero, the grill burner 32 is displayed. Is extinguished, and automatic grill cooking control is terminated.

  In the present invention, variations in the burned-up state caused by variations due to manufacturing errors and assembly errors of the components constituting the grill are suppressed, and also related to the usage environment such as a difference in heat generation amount of the supply gas at the place where the grill is used. It is possible to suppress the variation in the baked state caused by the variation, and to control the baked state to be close to the center value (expected value) at the time of designing the grill. In addition, it is possible to reflect the user's preference for cooking, and to enable good automatic grill cooking.

  In general, gas equipment (including grills) needs to use gas equipment according to the gas type supplied at the place of use, but even with the same gas type, the amount of heat generated by the gas varies. In addition, several types of gas are combined into one gas group, and the gas equipment is designed and manufactured so that it can be used for each gas group.

  For example, in the case of a gas device designed and manufactured for the gas type 13A, the gas type can be used regardless of whether the gas type is 13A or 12A.

  Therefore, it is assumed that a gas with a wide calorific value is supplied to a gas device designed and manufactured for a certain gas type at a place of use, and the influence on baking is great when automatic grill cooking is performed.

  Embodiments of the check mode for performing various corrections according to the present invention will be described below. In addition, the gas apparatus of this embodiment may use 13A or 12A gas types.

  First, the “correction program selection mode” will be described with reference to the flowchart of FIG.

  The power switch 13 is turned on to start the operation (# 01), and it is determined whether or not “the operation for shifting to the correction program selection mode” has been performed (# 02).

  The “transition operation to the correction program selection mode” is performed in a state in which heating is not performed without operating the operation units 14a to 14c of the stove unit 2 and the ignition / fire extinguishing switch 61 of the grill 3, and (1) the stove side grill The power switch 13 is turned on with the rice cooker switch 53b in the rear stove section 2 and the fried food switch 53a in the right stove section 2 pressed simultaneously, and (2) the rice cooker switch 53b in the rear stove section 2, The hot water switch 53c of the right cooking unit 2 is pressed simultaneously. Here, if the operation (2) is not performed within 10 seconds after the operation (1) is performed, the operation is cancelled.

  When the process shifts to the “correction program selection mode”, it is determined whether or not a “transition operation to a program mode for correcting an apparatus error” to be described later has been performed (# 03). "Program mode for correcting device error" (# 04), and if not, shift to (# 05).

  In (# 05), it is determined whether or not “the operation for shifting to a program mode for correcting an error such as a gas input” has been performed, and if so, a “program for correcting an error such as a gas input” described later. Mode "(# 06). If not, the process proceeds to (# 07).

  In (# 07), it is determined whether or not “transition operation to individual correction program mode” has been performed, and if it has been performed, the process proceeds to “individual correction program mode” described later (# 08) and is performed. If not, the process proceeds to (# 09).

  In (# 09), it is determined whether or not 10 minutes have passed without any operation since the shift to the “correction program selection mode”, and if 10 minutes have not passed, the process moves to (# 03). If 10 minutes have elapsed, the “correction program selection mode” is terminated (# 10).

  Next, each correction program mode will be described. First, “the operation for shifting to the program mode for correcting the error of the device” will be described.

  “Operation to shift to the program mode for correcting the error of the device” includes (1) pressing the “+” switch of the timer switch 62 of the grill setting input panel 6 three times, and (2) the timer of the grill setting input panel 6. Press the “−” switch of the switch 62 three times, (3) press the “+” switch of the timer switch 62 of the grill setting input panel 6 four times, and (4) “ The "-" switch is pressed three times, and (5) the "+" switch and the "-" switch of the timer switch 62 of the grill setting input panel 6 are simultaneously pressed.

  The “program mode for correcting device errors” (first correction mode) is intended to suppress variations in the burn-up state caused by variations due to manufacturing errors or assembly errors of the components that make up the grill. In addition, it is executed in a factory inspection inspection process or in a repair service center of a manufacturer with a small variation in the calorific value of the supplied gas, which is caused by a variation in the assembly of the equipment or a variation in the shape of the parts constituting the grill 3. To automatically correct errors in temperature detection characteristics caused by variations in the components of the equipment, such as variations in the flow of cooling air in the grill 30 and variations in the temperature detection characteristics of the temperature detection elements, by the control unit Executed.

  In the “program mode for correcting a device error”, the control unit executes an operation as shown in the flowchart of FIG. However, the ignition operation must be performed manually.

  It is determined whether the grill 3 has been ignited (# 11). The ignition operation of the grill 3 is performed by manually pressing the ignition / fire extinguishing switch 61 with the grill 3 unloaded (the state where there is no object to be heated 34). If the grill 3 has not been ignited, it is determined whether or not 10 minutes have passed without any operation or combustion since the transition to the “program mode for correcting device errors” (# 12), 10 If minutes have not elapsed, the process proceeds to (# 11), and if 10 minutes have elapsed, the "program mode for correcting device errors" is terminated (# 13). If the grill 3 is ignited in (# 11), it is determined whether 360 seconds have elapsed since the grill burner 32 ignited and combustion started (# 14), where 360 seconds have not elapsed. (# 14) is performed again, and if 360 seconds have elapsed, the process proceeds to (# 15).

  In (# 15), the grill burner 32 is extinguished to stop the combustion, and the temperature detected by the temperature detection means (upper temperature sensor 35) at 60 seconds after the grill burner 32 ignites and starts combustion is stored as T60. At the same time, the temperature detected by the temperature detecting means (upper temperature sensor 35) at 360 seconds after ignition of the grill burner 32 and the start of combustion is stored as T360. Then, the detected temperature rise temperature (ΔT1) from the time point 60 seconds after the start of combustion of the grill burner 32 to the time point 360 seconds (combustion time by error correction of the device) is calculated and stored from ΔT1 = T360−T60. , (# 16).

  In (# 16), it is determined whether or not the temperature rise (ΔT1) is within a predetermined range (−10% to + 10%) with respect to the reference value ST1 (70 K in this embodiment). Here, the reference value ST1 is a rise value of the temperature detected by the temperature detecting means 35 during the combustion time by correcting the error of the equipment when the grill 3 is used with no load. Stored in EEPROM. If it is not within the predetermined range, the process proceeds to (# 17), and if it is within the predetermined range, the process proceeds to (# 18).

  At (# 17), the LED on the timer display section of the grill setting input panel 6 blinks and an error is displayed, and the manual fire extinguishing operation of the grill 3 (that is, the ignition / fire extinguishing switch 61 of the grill setting input panel 6 is pressed). It is determined whether or not (operation) has been performed (# 19). If it has not been performed, (# 19) is performed again. If it has been performed, the timer display section of the grill setting input panel 6 goes off and an error occurs. The display ends (# 20), and the “program mode for correcting device errors” ends (# 21).

  In (# 18), it is determined whether or not the “+” switch and the “−” switch of the timer switch 62 of the grill setting input panel 6 are manually pressed within one minute after the grill burner 32 is extinguished. If so, the control unit calculates and stores the ratio ΔT1 / ST1 between ΔT1 and ST1 (# 22), and ends the “program mode for correcting the device error” (# 21). If they are not simultaneously pressed in (# 18), it is determined whether or not 10 minutes have passed without any operation or combustion since the transition to the “program mode for correcting device errors” (# 23). ) If 10 minutes have not elapsed, the process proceeds to (# 18), and if 10 minutes have elapsed, the “program mode for correcting device errors” is terminated (# 21).

  After performing this “program mode for correcting device errors” and storing ΔT1 / ST1, when performing automatic grilling, the total heating time TT obtained based on the information on the temperature rise gradient is set to TT ′ = TT The remaining heating time T2 = TT′−T1 = TT × ΔT1 / ST1-T1 based on the corrected total heating time TT ′ is displayed on the timer display unit.

  As a result, the “program mode for correcting the error of the device” is executed in a state where the calorific value of the supplied gas is small, and when ΔT1 / ST1 is smaller than 1, the manufacturing error or assembly of the parts constituting the device This is a state in which the detected temperature is detected by the temperature detecting means due to the variation caused by the error. For this reason, it is determined that the temperature rise gradient in the grill automatic cooking control is a small value compared to a state in which there is no variation due to manufacturing error or assembly error, and it is determined that a large object to be heated 34 is placed. Since there is a high possibility that the total heating time TT will be set to a long time, baking is performed by setting the baking time too long by correcting the total heating time TT to be shortened to TT ′ = TT × ΔT1 / ST1. Variations in state can be suppressed.

  On the other hand, when the “program mode for correcting the error of the device” is executed in a state where the calorific value of the supplied gas is small and ΔT1 / ST1 is larger than 1, the manufacturing error or assembly of the components constituting the device The temperature detected by the temperature detection means is detected by the temperature detection means due to variations due to errors, and the temperature rise gradient in automatic grill cooking control is larger than when there is no variation in each part or assembly. Since it is determined as a good value and it is determined that a small object to be heated 34 is placed and the total heating time TT is likely to be set to a short eye, the total heating time TT is set to TT ′ = TT × ΔT1. The variation in the burn-up state can be suppressed by correcting the length to be longer than / ST1.

  For example, in the “program mode for correcting the error of the device”, when ΔT1 = 68K, 68 / 70≈97.1%, so the control unit performs a total operation such that TT × 97.1% → TT ′. The heating time TT is corrected.

  Next, the “program mode for correcting an error such as gas input” (second correction mode) will be described.

  “Operation to shift to a program mode for correcting an error such as gas input” (1) Simultaneously press the “+” switch and the “−” switch of the timer switch 62 of the setting input panel 6 for grill, and (2) Grill The "+" switch and "-" switch of the timer switch 62 of the setting input panel 6 are simultaneously pressed again.

  “Program mode to correct errors such as gas input” suppresses variations in the burned-up state caused by differences in the amount of heat generated from the supply gas or variations at the place where the device is used, and the burn-up state can be set when the device is designed. This is executed to automatically correct the control constant by the control unit so as to approach the center value (expected value).

  In the “program mode for correcting an error such as gas input”, an operation as shown in the flowchart of FIG. 10 is executed by the control unit. However, the ignition operation must be performed manually.

  It is determined whether the grill 3 has been ignited (# 31). The ignition operation of the grill 3 is performed by manually pressing the ignition / fire extinguishing switch 61 with the grill 3 unloaded (the state where there is no object to be heated 34). If the grill 3 has not been ignited, it is determined whether or not 10 minutes have passed without any operation or combustion since the transition to the “program mode for correcting an error such as gas input” (# 32). If 10 minutes have not elapsed, the process proceeds to (# 31). If 10 minutes have elapsed, "program mode for correcting an error such as gas input" is terminated (# 33). If the grill 3 is ignited in (# 31), it is determined whether 360 seconds have elapsed since the grill burner 32 ignited and combustion started (# 34), where 360 seconds have not elapsed. (# 34) is performed again, and if 360 seconds have elapsed, the process proceeds to (# 35).

  In (# 35), the grill burner 32 is extinguished to stop the combustion, and the temperature detected by the temperature detection means (upper temperature sensor 35) at 60 seconds after the grill burner 32 ignites and starts combustion is stored as T60. At the same time, the temperature detected by the temperature detecting means (upper temperature sensor 35) at 360 seconds after ignition of the grill burner 32 and the start of combustion is stored as T360. Then, the detected temperature rise temperature (ΔT2) from the time point 60 seconds after the start of combustion of the grill burner 32 to the time point 360 seconds (combustion time by the error correction of the device) is calculated from ΔT2 = T360−T60 and stored. , (# 36).

  In (# 36), it is determined whether or not the temperature rise (ΔT2) is within a predetermined range (−10% to + 10%) with respect to the reference value ST2 (70 K in this embodiment). Here, the reference value ST2 is a rise value of the temperature detected by the temperature detection means 35 during the combustion time by the error correction of the equipment when the grill 3 is used with no load. Stored in EEPROM. If it is not within the predetermined range, the process proceeds to (# 37), and if it is within the predetermined range, the process proceeds to (# 38).

  In (# 37), the LED on the timer display section (upper side of the timer switch 62 in FIG. 6) of the grill setting input panel 6 blinks and an error is displayed, and the manual fire extinguishing operation of the grill 3 (that is, the grill setting input). It is determined whether or not the ignition / fire extinguishing switch 61 of the panel 6 has been pressed (# 39), and if not, (# 39) is performed again, and if so, the grill setting input panel 6 is turned off, the error display is finished (# 40), and the "program mode for correcting an error such as gas input" is finished (# 41).

  In (# 38), it is determined whether or not the “+” switch and the “−” switch of the timer switch 62 of the grill setting input panel 6 are manually pressed within one minute after the grill burner 32 is extinguished. If so, the control unit calculates and stores the ratio ΔT2 / ST2 between ΔT2 and ST2 (# 42), and ends the “program mode for correcting an error such as gas input” (# 41). If they are not simultaneously pressed in (# 38), it is determined whether or not 10 minutes have passed without any operation or combustion since the transition to the “program mode for correcting an error such as gas input”. # 43) If 10 minutes have not elapsed, the process proceeds to (# 38), and if 10 minutes have elapsed, the "program mode for correcting an error such as gas input" is terminated (# 41).

  After performing this “program mode for correcting errors such as gas input” and storing ΔT2 / ST2, when performing automatic cooking by the grill 3, the total heating time TT ( When the total heating time is corrected in the “program mode for correcting the error of the device”, the remaining heating time T2 is set to T2 = TT (or TT based on the corrected TT ′ = TT × ΔT1 / ST1). ') -T1 is obtained and displayed on the timer display section.

  By the way, when the calorific value of the gas supplied to the equipment is relatively close to the standard value as a constant of the calculation formula when calculating the total heating time TT by calculation based on the information of the temperature rise gradient in the grill automatic cooking control. Suitable standard calorific value constants, high calorific value constants suitable for high calorific value of gas supplied to equipment, and low calorific value constants suitable for low calorific value of gas supplied to equipment It is set.

  Before calculating and storing ΔT2 / ST2, a standard calorific value constant is used as a constant in a calculation formula used when calculating the total heating time TT based on information on the temperature rise gradient in grill automatic cooking control.

  After calculating and storing ΔT2 / ST2 in (# 42), if ΔT2 / ST2 is 95% (lower limit determination ratio) or more and 105% (upper limit determination ratio) or less, the temperature in the grill automatic cooking control The standard calorific value constant is used as a constant in the calculation formula for calculating the total heating time TT by calculation based on the information of the ascending gradient. When ΔT2 / ST2 is smaller than 95% (lower limit determination ratio), the grille automatic When the constant for the low calorific value is used as the constant of the calculation formula when calculating the total heating time TT by calculation based on the temperature rise gradient information in cooking control, and ΔT2 / ST2 is greater than 105% (upper limit determination ratio) In the automatic cooking control of the grill, the constant for the high calorific value is used as the constant of the calculation formula when the total heating time TT is obtained by calculation based on the information of the temperature rise gradient.

  For example, in the “program mode for correcting an error such as gas input”, when ΔT2 = 66K, 66 / 70≈94.3%, so the control unit detects the temperature increase gradient in the grill automatic cooking control. A low calorific value constant is used as a constant in a calculation formula for obtaining the total heating time TT by calculation based on the information. Further, when ΔT2 = 74K, 74 / 70≈105.7%, the control unit calculates when the total heating time TT is obtained by calculation based on the information on the temperature increase gradient in the automatic grill cooking control. A high calorific value constant is used as a constant in the equation.

  In this case, it is only necessary to use a three-stage value corresponding to the variation in the calorific value of the supply gas for the constant in the calculation formula of the total heating time TT, and correction can be easily performed.

  In addition, a value corresponding to the ratio (ΔT2 / ST2) may be used as a constant in the calculation formula for the total heating time TT, and is not particularly limited to three stages. Further, by using a function of the ratio (ΔT2 / ST2) as a constant in the calculation formula of the total heating time TT, fine correction can be performed according to variations in the heat generation amount of the supply gas.

  Next, the “individual correction program mode” will be described. “Transition to the individual correction program mode” is either (1) operating the menu switch 64 to select one menu to correct the heating time from the menu of “appearance grilling”, “fillet”, “dried fish”, or an a la carte menu The switch 65 is operated to select one menu whose heating time is to be corrected from the menus of “toast”, “pizza”, and “baked rice ball”.

  In the “individual correction program mode”, the result of the user's automatic cooking on the grill 3 (that is, the state of standardization set by the equipment manufacturer) is the result of the user's expectation of the adjustment. When it is different from the state, it is executed in order to reflect the user's preference in the cooking in the grill automatic cooking.

  In the “individual correction program mode”, an operation as shown in the flowchart of FIG. 11 is executed by the control unit.

  It is determined whether or not the “+” switch of the timer switch 62 of the grill setting input panel 6 has been pressed (# 51). When the button is pressed, it is determined whether or not the total heating time is extended by 10% in the “individual correction program mode” (# 52), and if it is extended, the process proceeds to (# 53). If not extended, the extension rate of the total heating time set in the “individual correction program mode” is increased by 1% (# 54), and the process proceeds to (# 51).

  In (# 53), it is determined whether or not the “−” switch of the timer switch 62 of the grill setting input panel 6 has been pressed, and if so, the total heating time in the “individual correction program mode”. Is determined to be extended by -10% (that is, shortened by 10%) (# 55). If it is extended by -10%, the process proceeds to (# 51), and is not extended by -10%. In the “individual correction program mode”, the extension rate of the total heating time set is shortened by 1% (# 56), and the process proceeds to (# 51).

  If the operation is not pushed in (# 53), 10 minutes have passed without any operation or combustion since shifting to the “individual correction program mode”, or the power switch 13 is turned OFF ) Is determined (# 57), the process proceeds to (# 51) if neither 10 minutes have elapsed nor turned OFF, and if 10 minutes have elapsed or turned OFF, the “individual correction program mode” is set. End (# 58).

  Thereby, a user's liking can be reflected in the heating-and-discharging in grill automatic cooking.

  However, even in the correction by the “individual correction program mode”, the total heating time TT is extended or shortened by a maximum of 10%, and cannot be further extended or shortened.

  In addition, the value set in the “individual correction program mode” can be reset. For resetting, after shifting to the “individual correction program mode”, the “+” switch and the “−” switch of the timer switch 62 are simultaneously pressed for 5 seconds or more. As a result, all the values set in the “individual correction program mode” in the past can be erased and returned to the factory-set state.

  Next, a second embodiment will be described. In the present embodiment, in automatic grill cooking, after the automatic cooking mode is started and the grill burner 32 is manually ignited, the control unit controls the flow rate adjusting valve 44 to adjust the heating amounts of the upper burner 32a and the lower burner 32b, respectively. When the predetermined heating amount switching time according to the cooking menu elapses, the heating amount of the upper burner 32a and the lower burner 32b is changed and switched, and the combustion is stopped for a predetermined time or when the predetermined temperature is reached. Take control.

The heating amount switching time is set to be shorter than a predetermined value when the ratio (ΔT1 / ST1) is equal to or larger than the threshold value or larger than the threshold value , and is set to be longer than the predetermined value when the ratio is smaller than or smaller than the threshold value. As a result, errors in temperature detection characteristics such as variations in the flow of cooling air in the grill cabinet due to variations due to manufacturing errors and assembly errors of the components that make up the grill are corrected by the control unit, and the heating amount switching time Automatic control of the grill is executed so that the grill becomes appropriate, and variations in the baking due to individual differences of the grill can be suppressed.

As another example of this embodiment, the amount of heating switching time, the ratio (ΔT2 / ST2) said set shorter than a predetermined value in the case or another threshold or larger than the threshold value of the threshold, the threshold value is smaller than or less than the threshold value In this case, it may be set longer than a predetermined value. As a result, at the place where the grill is used, it is possible to suppress the variation in baking that occurs due to the variation in the heat generation amount of the supply gas, and to correct the heating amount switching time.

As still another example of the present embodiment, the heating amount switching control is performed by starting the automatic cooking mode and manually igniting the grill burner 32, and then the control unit controls the flow rate adjusting valve 44 to control the upper burner 32a and the lower burner 32b. When the predetermined heating amount switching temperature corresponding to the cooking menu is reached, the heating amount of the upper burner 32a and the lower burner 32b is changed and switched, and combustion is performed for a predetermined time or when the predetermined temperature is reached. The heating amount switching temperature at this time is set to be lower than a predetermined value when the ratio (ΔT1 / ST1) is smaller than or smaller than the threshold , and the ratio (ΔT1 / ST1) is If the threshold is greater than or greater than the threshold, it may be set higher than the predetermined value.

  As a result, errors in temperature detection characteristics such as variations in the flow of cooling air in the grill cabinet due to variations due to manufacturing errors and assembly errors of the components that make up the grill are corrected by the control unit, and the heating amount switching temperature is corrected. Since automatic control of the grill is executed so as to make it appropriate, it is possible to suppress variations in the baking due to individual differences in the grill.

Next, a third embodiment will be described. In the present embodiment, in the automatic grill cooking, after the automatic cooking mode is started and the grill burner 32 is manually ignited, the grill burner 32 is turned on when the temperature in the grill cabinet 30 (detected temperature by the temperature detecting means) reaches the fire extinguishing determination temperature. When performing automatic fire extinguishing control to extinguish fire, the fire extinguishing judgment temperature is set lower than a predetermined value when ΔT1 / ST1 is smaller than or less than the threshold, and higher than the predetermined value when greater than or equal to the threshold. It is to set. As a result, errors in temperature detection characteristics such as variations in the flow of cooling air in the grill due to variations due to manufacturing errors and assembly errors of the components that make up the grill are corrected by the control unit, and the judgment temperature for fire extinguishing Since automatic control of the grill is executed so as to make it appropriate, it is possible to suppress variations in the baking due to individual differences in the grill.

  In the first to third embodiments, the grill burner 32 is burned with the grill 3 in a no-load state when executing the “program mode for correcting an error in the device” or the “program mode for correcting an error such as gas input”. However, a cooked product (for example, three horses) or a pseudo load (a container 7 shown in FIG. 7 with 150 ml of water) is placed on the grill 33 of the grill 3 and the grill burner 32 is mounted. It may be burned. As a result, correction in a state closer to actual use is possible.

  In the first to third embodiments, the temperature detected by the temperature detecting means (upper temperature sensor 35) at 60 seconds after the grill burner 32 ignites and starts combustion in (# 15) is T60, and the grill burner Although the temperature detected by the temperature detecting means (upper temperature sensor 35) at the time of 360 seconds after ignition of 32 and the start of combustion is T360, other values may be used instead of 60 seconds and 360 seconds, respectively. Similarly, the detected temperature of the temperature detection means (upper temperature sensor 35) at 60 seconds after the grill burner 32 ignites and starts combustion in (# 35) is T60, and 360 seconds after the grill burner 32 ignites and combustion starts. Although the detected temperature of the temperature detection means (upper temperature sensor 35) at the time is T360, other values may be used instead of 60 seconds and 360 seconds, respectively, and values different from those in (# 15) may be used. It may be used.

  The reference value ST1 and the reference value ST2 are also set to 70K, but different values may be used.

  In (# 16), it was determined whether or not the temperature rise (ΔT1) was within a predetermined range (−10% to + 10%) with respect to the reference value ST1, but the upper and lower limits of the predetermined range were + 10% and −10%, respectively. Alternatively, other values may be used. Similarly, in (# 36), it is determined whether or not the temperature rise (ΔT2) is within a predetermined range (−10% to + 10%) with respect to the reference value ST2. Instead of + 10% and -10% for the upper and lower limits, values other than the good values may be used.

  Further, although the determination time is 10 minutes in (# 09) (# 12) (# 23) (# 32) (# 43) (# 57), other values may be used.
