Description

  The present invention relates to an indirect heating type double-sided grill and a stove.

  2. Description of the Related Art Conventionally, a double-sided grill using an indirect heating system in which an upper burner is arranged and a cooking space in which a cooking dish is accommodated and a heating space in which a lower burner is arranged is vertically separated is known. For example, an upper burner and a lower burner provided in the central combustion part and the peripheral combustion part are provided in the grill part of the gas stove, and a removable baking cover is provided in the upper part of the grill pan so that the user can arbitrarily separate the burner parts. There has been proposed a gas stove grill device that burns simultaneously or simultaneously and cooks by direct fire or indirect heat using a grill cover (see, for example, Patent Document 1). This type of grill directly heats the upper surface of the object to be cooked by radiant heat from the upper burner or heat convection in the cooking space, while being transferred through the heating space and the cooking space from the lower burner. It is comprised so that the lower surface of to-be-cooked material may be heated indirectly by heat. And this kind of grill has the advantage that it is excellent in cleanability because there is no oil dripping to the lower burner.

In the present embodiment, the grill door 24 can be pulled out in the front-back direction. The grill door 24 may be configured to be rotatable.

-Internal structure-
As shown in FIGS. 2, 5, and 6, the space inside the grill cabinet 21 is partitioned vertically by an intermediate plate 30 arranged substantially horizontally. Far-infrared enamel processing is applied to the upper and lower surfaces of the middle plate 30. A cooking space 31 is formed above the middle plate 30, and a heating space 32 is formed below the middle plate 30. In the cooking space 31, an upper burner 35 (see FIGS. 2 and 4) having a rectangular shape in plan view is provided in the approximate center of the upper wall of the grill cabinet 21. The upper burner 35 includes a plurality of flame holes (not shown) on the lower surface, and forms a flame downward in the flame holes. And the cooking plate 10 is mounted on the upper surface of the intermediate plate 30 so as to be freely put in and out. The cooking dish 10 has an uneven surface at the bottom, but it may be planar. An object to be cooked such as fish (not shown) is placed on the uneven surface of the cooking dish 10. The upper side surface of the object to be cooked is directly heated by the amount of heat from the upper burner 35. The cooking pan 10 may be detachably connected to the lower rear portion of the grill door 24. In that case, the cooking pan 10 can be pulled out to the outside of the grill cabinet 21 by pulling the grill door 24 forward.

  As shown in FIG. 5, an igniter 37 and a flame detector 45 are provided in the vicinity of the upper burner 35. The igniter 37 ignites the upper burner 35 by operating based on a control command from the CPU 51 described later. The flame detector 45 detects ignition or misfire of the upper burner 35. The flame detector 45 only needs to detect any of the heat, light, and electrical characteristics of the combustion flame. For example, the flame detector 45 uses a thermocouple or electrical characteristics to detect heat. The frame rod and the light detection type are classified into three types (ultraviolet type, visible light type, and infrared type) depending on the wavelength to be detected.

  In addition, as shown in FIGS. 2, 5, and 6, an upper duct 39 is provided in the rear portion of the cooking space 31. The upper duct 39 communicates with the upper exhaust port 40 provided in the rear part of the upper wall of the grill cabinet 21. Therefore, the combustion exhaust gas in the cooking space 31 is discharged from the upper exhaust port 40 to the outside through the upper duct 39. A frame trap 41 is installed at the upper exhaust port 40. The flame trap 41 prevents a flame from being emitted from the upper exhaust port 40 in the event that a fish placed on the cooking pan 10 ignites.

  On the other hand, the heating space 32 is provided with a lower burner 36 having a substantially U shape in plan view. The lower burner 36 includes a plurality of flame holes (not shown) along a substantially U-shaped inner peripheral surface, and the flame is formed in the flame holes inward. Thereby, since the intermediate | middle board 30 and the cooking pan 10 are heated from the downward direction with the calorie | heat amount from the lower burner 36, the lower surface of a to-be-cooked object is heated indirectly. In the vicinity of the lower burner 36, igniters 38A and 38B (see FIGS. 5 and 6) and a flame detector 46 (see FIG. 5) are provided. The igniters 38A and 38B are provided in the substantially U-shaped portions of the lower burner 36 facing each other (see FIG. 6), and operate based on the control command of the CPU 51 to ignite the lower burner 36. The flame detector 46 detects ignition and misfire of the lower burner 36.

  As shown in FIGS. 2 and 5, a lower duct 42 is provided in the rear part of the heating space 32. The lower duct 42 communicates with a lower exhaust port 43 provided on the upper wall of the grill cabinet 21 and adjacent to the rear of the upper exhaust port 40. Therefore, the combustion exhaust gas in the heating space 32 is discharged from the lower exhaust port 43 to the outside through the lower duct 42. As described above, the grill device 20 includes the above-described structure, thereby configuring an indirect heating type double-sided grill that heats the upper and lower surfaces of the cooking object placed on the cooking pan 10 and cooks them. And in the grill apparatus 20, since there is no dripping of the oil to the lower burner 36, it is excellent in cleaning property.

  Next, referring to FIG. 7, a mechanism for switching the heating power of the upper burner 35 and the lower burner 36 in the grill device 20 will be described. The stove 1 is provided with a gas supply pipe 61 for supplying gas to the grill device 20. The gas supply pipe 61 branches into a first gas supply pipe 62 and a second gas supply pipe 63 on the way. The first gas supply pipe 62 supplies gas to the upper burner 35, and the second gas supply pipe 63 supplies gas to the lower burner 36. A safety valve 47 is provided in front of the branch to the first gas supply pipe 62 and the second gas supply pipe 63.

  The first gas supply pipe 62 is provided with a thermal power adjusting device 19 and a thermal power control mechanism unit 70, respectively. The thermal power adjusting device 19 is provided on the downstream side of the thermal power control mechanism 70, and is linked to the operation of the upper heating adjustment knob 17A (see FIG. 1) of the thermal power adjustment knob 17 provided on the front surface of the stove 1. The amount of gas supplied to 35 is increased or decreased. The thermal power control mechanism unit 70 is composed of a plurality of flow paths and a plurality of electromagnetic valves in order to improve cooking performance and safety of the stove 1. The thermal power control mechanism unit 70 includes bypass pipes 64 and 65, electromagnetic valves 71 to 73, and the like. The electromagnetic valve 71 is provided in the middle of the first gas supply pipe 62. The bypass pipes 64 and 65 are respectively connected between the upstream side and the downstream side of the electromagnetic valve 71. The electromagnetic valve 72 is provided in the bypass pipe 65. The electromagnetic valve 73 is provided on the downstream side of the position where the first gas supply pipe 62 and the bypass pipes 64 and 65 join each other. The electromagnetic valves 71 and 72 are keep solenoid valves for adjusting the gas flow rate. The electromagnetic valve 73 is a gas blocking keep solenoid valve.

  For example, in the thermal power control mechanism unit 70, by opening and closing the electromagnetic valves 71 and 72, respectively, the gas flow rate flowing through the thermal power control device 19 can be adjusted in three stages: a first flow rate, a second flow rate, and a third flow rate. The first flow rate when both solenoid valves 71 and 72 are opened, the second flow rate when any one of the solenoid valves 71 and 72 is closed, and the third flow rate when both solenoid valves 71 and 72 are closed. Become. When the gas flows into the upper burner 35 at the first flow rate, the second flow rate, and the third flow rate, the heating power of the upper burner 35 when the heating power adjustment knob 17A (see FIG. 1) is adjusted to the maximum is amplified. It becomes firepower, normal firepower, and restraint firepower. Therefore, the grill device 20 can switch the heating power of the upper burner 35 in the cooking space 31 in three stages. The thermal power control mechanism unit 70 corresponds to the “switching unit” of the present invention.

  Although not described in detail, the second gas supply pipe 63 is also provided with a thermal power adjusting device (not shown) and a thermal power control mechanism (not shown) corresponding to the lower burner 36, respectively. The thermal power adjustment device increases or decreases the amount of gas supplied to the lower burner 36 in conjunction with the operation of the lower heat adjustment knob 17B (see FIG. 1) of the thermal power adjustment knob 17. Therefore, the grill device 20 can switch the heating power of the lower burner 36 in three stages even in the heating space 32.

  The electrical configuration of the stove 1 will be described with reference to FIG. The stove 1 includes a control circuit 50. The control circuit 50 is provided with a timer, a grill timer, an I / O interface, etc. (not shown) in addition to the CPU 51, ROM 52, RAM 53, and nonvolatile memory 54. The timer and grill timer operate by program. The CPU 51 performs overall control of various operations of the stove 1. The ROM 52 stores a grill control program and the like in addition to the various programs of the stove 1. The grill control program is for executing grill control processing (see FIGS. 10 to 13 and FIG. 15), which will be described later. The RAM 53 temporarily stores various information. The nonvolatile memory 54 stores various parameters.

  The control circuit 50 includes a power supply circuit 81, a switch input circuit 82, a thermistor input circuit 83, a flame detection circuit 84, an igniter circuit 85, a sensor input circuit 86, a buzzer circuit 87, a voice synthesis circuit 88, a safety valve circuit 90, and an electromagnetic valve circuit. 91 etc. are connected to each other. The power supply circuit 81 supplies power to various circuits using two dry batteries mounted on the battery case 14 (see FIG. 1). The power supply circuit 81 includes a transistor switch (not shown). The switch input circuit 82 detects pressing of the ignition switches 11 to 13 and inputs it to the control circuit 50. The thermistor input circuit 83 inputs detection signals from the thermistors 5B and 6B to the control circuit 50. The flame detection circuit 84 inputs detection signals from the flame detectors 45 and 46 to the control circuit 50. The igniter circuit 85 operates igniters (not shown) provided in the right stove 5 and the left stove 6 and igniters 37, 38 </ b> A, 38 </ b> B provided in the grill cabinet 21 based on the control signal of the CPU 51.

  The sensor input circuit 86 inputs detection signals from the pan sensors 5A and 6A. The buzzer circuit 87 drives the piezoelectric buzzer 77 based on the control signal from the CPU 51. The voice synthesizing circuit 88 synthesizes the voice of the voice guide output from the speaker 78 based on the control of the CPU 51. The safety valve circuit 90 opens and closes the safety valve 47 (see FIG. 7) based on the control of the CPU 51. The electromagnetic valve circuit 91 opens and closes the electromagnetic valves 71 to 73 (see FIG. 7) based on the control of the CPU 51. Although not shown, each of the gas supply pipes of the right stove 5 and the left stove 6 is also provided with a thermal power adjustment device, a thermal power control mechanism, a safety valve, and the like, similarly to the grill device 20, and a safety valve circuit 90 is provided. And the solenoid valve circuit 91 respectively.

  The ignition switches 11 to 13 are connected in parallel to the switch input circuit 82 and the positive side of the dry battery stored in the battery case 14, respectively. The negative side of the dry battery is connected to the power supply circuit 81, and the switch input circuit 82 is also connected to the power supply circuit 81. When one of the ignition switches 11 to 13 is pressed by the user, the power of the dry battery is supplied to the power circuit 81 via the switch input circuit 82, and the transistor switch of the power circuit 81 is turned on. Thereby, current flows from the power supply circuit 81 to various circuits, and the power supply of the stove 1 is turned on. The switch input circuit 82 detects which of the ignition switches 11 to 13 is pressed, and inputs the detection signal to the control circuit 50. Therefore, the CPU 51 can determine which of the ignition switches 11 to 13 has been turned on by pressing the ignition switch 11 to 13.

  Next, a grill control process executed by the CPU 51 will be described with reference to FIG. For example, when cooking is performed by the grill device 20, the user opens the grill door 24 toward the front, and places the cooking pan 10 on which the food is to be placed at a predetermined position on the upper surface of the intermediate plate 30 (FIGS. 2 and 2). 5). For example, by providing a protrusion or the like on the back side of the upper surface of the middle plate 30 and placing the cooking dish 10 in contact with the protrusion, the cooking dish 10 may be automatically placed in a predetermined position. The user presses the ignition switch 12 after closing the grill door 24. When it is detected that the ignition switch 12 is pressed, the CPU 51 reads the “grill control program” from the ROM 52 and executes this processing. In the present embodiment, a case where fish or the like is baked as an object to be cooked is described as an example, and the cooking time is assumed to be around 15 minutes.

  The grill control program of the present embodiment switches at least the heating power of the upper burner 35, and the average heat amount per unit time (1 minute in the present embodiment) from the upper burner 35 until a predetermined time elapses from the start of cooking. However, the heating power of the upper burner 35 is controlled so as to be lower than the average amount of heat per unit time from the upper burner 35 after a predetermined time has elapsed. In this embodiment, five patterns will be described as specific examples.

-Pattern 1
As shown in FIG. 9, in pattern 1, at the start of cooking, control is performed to ignite the upper burner 35 after the ignition of the lower burner 36. As shown in FIG. 10, first, the CPU 51 ignites the lower burner 36 (S1). As shown in FIG. 7, ignition is performed by opening the safety valve 47 provided in the gas supply pipe 61 and all the solenoid valves of the thermal power control mechanism (not shown) provided in the second gas supply pipe 63, thereby igniter. This is done by operating 38A and 38B, respectively. When the flame detector 46 detects flames in the lower burner 36, the CPU 51 switches the lower burner 36 to normal heating power (S2). Therefore, the heating space 32 is heated before the cooking space 31. Further, the CPU 51 initializes the timer t to 0 (S3) and starts measuring time (S4). Note that the count value of the timer t is stored in the RAM 53.

  Next, the CPU 51 determines whether or not one minute has elapsed since the lower burner 36 was ignited (S5). Until one minute has elapsed (S5: NO), the CPU 51 stands by. When one minute has passed (S5: YES), the CPU 51 ignites the upper burner 35 with the igniter 37 (S6) and burns it with the amplified thermal power (S7). Thereafter, the upper burner 35 maintains the amplified thermal power, and the lower burner 36 maintains the normal thermal power to heat the upper and lower surfaces of the object to be cooked.

  As described above, in pattern 1, by igniting the upper burner 35 after the lower burner 36 is ignited, the amount of heat given from the upper burner 35 to the object to be cooked can be suppressed in the initial stage of cooking. Thereby, the rise of the amount of heat given from the upper burner 35 to the object to be cooked in the early stage of cooking can be made closer to the rise of the amount of heat given from the lower burner 36 to the object to be cooked. Furthermore, when the amount of heat given to the object to be cooked from the upper burner 35 until 5 minutes have passed since ignition is converted to an average amount of heat per minute, the average amount of heat is 5 minutes after ignition. It is lower than the average heat per minute. Thereby, in the initial stage of cooking, the amount of heat given from the upper burner 35 to the object to be cooked can be suppressed, so that the heating by the upper burner 35 and the heating by the lower burner 36 can be balanced. Therefore, the grill device 20 can maintain a good balance of baking on the upper and lower surfaces of the object to be cooked.

  Thereafter, the CPU 51 determines whether or not there has been a fire extinguishing operation by pressing the ignition switch 12 again (S8). Until the fire extinguishing operation is performed (S8: NO), the CPU 51 continues to maintain the heating power of the upper burner 35 and the lower burner 36. When there is a fire extinguishing operation (S8: YES), the CPU 51 closes the safety valve 47 to extinguish both the upper burner 35 and the lower burner 36 (S9), and ends this process.

-Pattern 2-
As shown in FIG. 9, in the pattern 2, after ignition, the upper burner 35 is combusted with normal thermal power, and control is performed to switch to amplified thermal power after 5 minutes from ignition. As shown in FIG. 11, first, the CPU 51 ignites the upper burner 35 and the lower burner 36 (S11). When the flame detectors 45 and 46 detect flames in the upper burner 35 and the lower burner 36, the CPU 51 switches both the upper burner 35 and the lower burner 36 to normal heating power (S12). Further, the CPU 51 initializes the timer t to 0 (S13) and starts measuring time (S14). The temperature of the cooking pan 10 gradually increases.

  Next, the CPU 51 determines whether or not 5 minutes have elapsed as a predetermined time since both the upper burner 35 and the lower burner 36 were ignited (S15). Until 5 minutes have elapsed (S15: NO), the CPU 51 stands by. When 5 minutes have elapsed (S15: YES), the CPU 51 switches only the thermal power of the upper burner 35 to amplified thermal power (S16), and the lower burner 36 maintains normal thermal power. Therefore, the upper burner 35 heats the upper and lower surfaces of the food to be cooked with amplified thermal power and the lower burner 36 with normal thermal power.

  Thus, in Pattern 2, the amount of heat given from the upper burner 35 to the object to be cooked in the initial stage of cooking is switched to the normal thermal power instead of the amplified thermal power instead of the amplified thermal power in Pattern 2, as in Pattern 1. Can rise close to the rise of the amount of heat given from the lower burner 36 to the object to be cooked. Furthermore, also in the pattern 2, when the amount of heat given from the upper burner 35 to the food to be cooked until 5 minutes elapses after ignition, when the average amount of heat per minute is converted, the average amount of heat is ignited. It is lower than the average amount of heat per minute after 5 minutes. Thereby, in the initial stage of cooking, the amount of heat given from the upper burner 35 to the object to be cooked can be suppressed, so that the heating by the upper burner 35 and the heating by the lower burner 36 can be balanced. Therefore, the grill device 20 can maintain a good balance of baking on the upper and lower surfaces of the object to be cooked.

  Thereafter, the CPU 51 determines whether or not there has been a fire extinguishing operation by pressing the ignition switch 12 again (S17). Until the fire extinguishing operation is performed (S17: NO), the CPU 51 continues to maintain the heating power of the upper burner 35 and the lower burner 36. If there is a fire extinguishing operation (S17: YES), the CPU 51 closes the safety valve 47 to extinguish both the upper burner 35 and the lower burner 36 (S18), and ends this process.

-Pattern 3-
As shown in FIG. 9, in the pattern 3, after the ignition, the heating power of the upper burner 35 is alternately switched between the amplified heating power and the normal heating power every minute, and the control is performed to switch to the amplified heating power after 5 minutes from ignition. As shown in FIG. 12, first, the CPU 51 ignites the upper burner 35 and the lower burner 36 (S21), and then burns the upper burner 35 with amplified thermal power and the lower burner 36 with normal thermal power (S22). Further, the CPU 51 initializes the timer t to 0 (S23) and starts measuring time (S24).

  Next, the CPU 51 switches the heating power of the upper burner 35 alternately between the normal heating power and the amplified heating power every minute (S25) while the heating power of the lower burner 36 remains normal. For example, as shown in pattern 3 in FIG. 9, after ignition, combustion is performed with amplified thermal power, and after ignition, switching to normal thermal power is performed one minute later, and further, switching to amplified thermal power is performed one minute later. Next, the CPU 51 determines whether or not 5 minutes have elapsed since ignition (S26). Until 5 minutes have passed (S26: NO), the CPU 51 continues the operation of switching the heating power every minute (S25). When 5 minutes have elapsed since ignition (S26: YES), the CPU 51 switches only the upper burner 35 to the amplified thermal power (S27). After that, the upper burner 35 heats the upper and lower surfaces of the cooking object with amplified thermal power and the lower burner 36 with normal thermal power.

  Thus, in pattern 3, by switching the heating power of the upper burner 35 in the initial stage of cooking alternately between the amplified thermal power and the normal thermal power, the upper burner 35 in the initial stage of cooking is changed from the upper burner 35 to the object to be cooked in the same manner as in patterns 1 and 2. The rise of the amount of heat given can be brought close to the rise of the amount of heat given from the lower burner 36 to the object to be cooked. Furthermore, also in the pattern 3, when the amount of heat given from the upper burner 35 to the food to be cooked until 5 minutes have passed since ignition, when the average amount of heat per minute is converted, the average amount of heat is ignited. It is lower than the average heat per minute after 5 minutes. Thereby, in the initial stage of cooking, the amount of heat given from the upper burner 35 to the object to be cooked can be suppressed, so that the heating by the upper burner 35 and the heating by the lower burner 36 can be balanced. Therefore, the grill device 20 can maintain a good balance of baking on the upper and lower surfaces of the object to be cooked.

  Thereafter, the CPU 51 determines whether or not there has been a fire extinguishing operation by pressing the ignition switch 12 again (S28). Until the fire extinguishing operation is performed (S28: NO), the CPU 51 continues to maintain the heating power of the upper burner 35 and the lower burner 36. When there is a fire extinguishing operation (S28: YES), the CPU 51 closes the safety valve 47 to extinguish both the upper burner 35 and the lower burner 36 (S29), and ends this process.

-Pattern 4-
As shown in FIG. 9, in pattern 4, after ignition, the upper burner 35 is burned with amplified thermal power. After 3 minutes have elapsed after ignition, only the upper burner 35 is extinguished once, and after 5 minutes have elapsed after ignition, the upper burner 35 Control to re-ignite. As shown in FIG. 13, first, the CPU 51 ignites the upper burner 35 and the lower burner 36 (S31), and then switches the upper burner 35 to amplified thermal power and the lower burner 36 to normal thermal power (S32). Further, the CPU 51 initializes the timer t to 0 (S33) and starts measuring time (S34). The temperature of the cooking pan 10 rises quickly.

  Next, the CPU 51 determines whether or not 3 minutes have elapsed since both the upper burner 35 and the lower burner 36 were ignited (S35). Until 3 minutes have elapsed (S35: NO), the CPU 51 stands by. When 3 minutes have elapsed (S35: YES), the CPU 51 extinguishes only the upper burner 35 (S36). The lower burner 36 is continuously burned with normal heating power.

  Subsequently, the CPU 51 determines whether or not 5 minutes have elapsed since ignition (S37). Until 5 minutes have elapsed (S37: NO), the CPU 51 stands by. When 5 minutes have elapsed (S37: YES), the CPU 51 re-ignites the upper burner 35 (S38) and switches to normal heating power (S39). After that, the upper burner 35 heats the upper and lower surfaces of the cooking object with amplified thermal power and the lower burner 36 with normal thermal power.

  As described above, in Pattern 4, the upper burner 35 that burns with the amplified thermal power in the initial stage of cooking is extinguished once, so that the amount of heat given from the upper burner 35 in the initial stage of cooking to the object to be cooked is similar to Patterns 1 to 3. Can be brought close to the rise of the amount of heat given from the lower burner 36 to the object to be cooked. Furthermore, also in the pattern 4, when the amount of heat given from the upper burner 35 to the object to be cooked during 5 minutes after ignition is converted into the average amount of heat per minute, the average amount of heat is ignited. It is lower than the average amount of heat per minute after 5 minutes. Thereby, in the initial stage of cooking, the amount of heat given from the upper burner 35 to the object to be cooked can be suppressed, so that the heating by the upper burner 35 and the heating by the lower burner 36 can be balanced. Therefore, the grill apparatus 20 can improve the balance of the baking of the upper and lower surfaces of the object to be cooked. Moreover, the upper side surface of a to-be-cooked object can be heated favorably by reigniting the upper burner 35 after extinguishing the fire.

  Thereafter, the CPU 51 determines whether or not there has been a fire extinguishing operation by pressing the ignition switch 12 again (S40). Until the fire extinguishing operation is performed (S40: NO), the CPU 51 continues to maintain the heating power of the upper burner 35 and the lower burner 36. When there is a fire extinguishing operation (S40: YES), the CPU 51 closes the safety valve 47 to extinguish both the upper burner 35 and the lower burner 36 (S41), and ends this process.

-Pattern 5-
Pattern 5 is a modification of pattern 4. In Pattern 4, the timing for re-igniting the upper burner 35 is a predetermined time after ignition. However, in Pattern 5, after the upper burner 35 is extinguished, the temperature of the cooking pan 10 is changed. Control is performed to re-ignite at a p-timing lower than a predetermined temperature (for example, 350 ° C.).

  Here, in order to measure the temperature of the cooking pan 10, for example, as shown in FIG. 14, a thin button type thermistor 95 can be provided in the front portion of the upper surface of the intermediate plate 30. In such a configuration, when the cooking dish 10 is placed at a predetermined position on the upper surface of the intermediate plate 30, the front portion of the bottom lower surface of the cooking dish 10 comes into contact with the thermistor 95. Thereby, the thermistor 95 can measure the temperature of the cooking pan 10.

  As shown in FIG. 15, first, the CPU 51 ignites the upper burner 35 and the lower burner 36 (S51), and then switches the upper burner 35 to amplified thermal power and the lower burner 36 to normal thermal power (S52). Further, the CPU 51 initializes the timer t to 0 (S53) and starts measuring time (S54). Since the cooking dish 10 is heated from the upper side with amplified thermal power and from the lower side with normal thermal power, the temperature of the cooking dish 10 rises quickly.

  Next, the CPU 51 determines whether or not 3 minutes have elapsed since both the upper burner 35 and the lower burner 36 were ignited (S55). Until 3 minutes have elapsed (S55: NO), the CPU 51 stands by. When 3 minutes have elapsed (S55: YES), the CPU 51 extinguishes only the upper burner 35 (S46). The lower burner 36 is continuously burned with normal heating power. Up to this point, the pattern 4 is the same. After the upper burner 35 is extinguished, the temperature of the cooking pan 10 gradually decreases.

  Next, the CPU 51 measures the temperature of the cooking pan 10 using the thermistor 95 (S57). As described above, the thermistor 95 is in contact with the bottom surface of the bottom of the cooking dish 10, and thus the temperature of the cooking dish 10 can be measured. The CPU 51 determines whether or not the measured value of the thermistor 95 has dropped below a predetermined temperature (for example, 250 ° C.) (S58). If the measured value is still 250 ° C. or higher (S58: NO), the CPU 51 continues to monitor the temperature of the cooking pan 10 (S57, S58). And when a measured value falls to less than 250 degreeC (S58: YES), CPU51 reignites the upper burner 35 (S59), and switches to normal heating power (S60). After that, the upper burner 35 heats the upper and lower surfaces of the cooking object with amplified thermal power and the lower burner 36 with normal thermal power.

  Thus, also in pattern 5, after the lapse of 3 minutes from ignition, once the upper burner 35 is extinguished, similarly to pattern 4, the rise of the amount of heat given from the upper burner 35 to the cooking object at the initial stage of cooking is increased. The rising of the amount of heat given to the food from the lower burner 36 can be approached. Furthermore, also in the pattern 5, when the amount of heat given to the food to be cooked from the upper burner 35 until 5 minutes have passed since ignition, when the average amount of heat per minute is converted, the average amount of heat is ignited. It is lower than the average amount of heat per minute after 5 minutes. Thereby, in the initial stage of cooking, the amount of heat given from the upper burner 35 to the object to be cooked can be suppressed, so that the heating by the upper burner 35 and the heating by the lower burner 36 can be balanced. Therefore, the grill device 20 can maintain a good balance of baking on the upper and lower surfaces of the object to be cooked. Moreover, after the upper burner 35 is extinguished once, the temperature of the cooking pan 10 is measured by the thermistor 95, and the upper burner 35 is re-ignited based on the measured value. Therefore, the cooking object placed on the cooking pan 10 is cooked. Can be baked more reliably.

  Thereafter, the CPU 51 determines whether or not there has been a fire extinguishing operation by pressing the ignition switch 12 again (S61). Until the fire extinguishing operation is performed (S61: NO), the CPU 51 continues to maintain the heating power of the upper burner 35 and the lower burner 36. When there is a fire extinguishing operation (S61: YES), the CPU 51 closes the safety valve 47 to extinguish both the upper burner 35 and the lower burner 36 (S62), and ends this process.

  As described above, the grill device 20 of the present embodiment is mounted on the stove 1. The grill device 20 includes a cooking space 31 on the upper side of the middle plate 30 and a heating space 32 on the lower side of the middle plate 30 by partitioning the inside of the grill cabinet 21 with the middle plate 30. The cooking space 31 is provided with an upper burner 35. On the upper surface of the middle plate 30, a cooking dish 10 for placing an object to be cooked is stored in a freely retractable manner. A lower burner 36 is provided in the heating space 32. The amount of heat from the upper burner 35 is directly given to the object to be cooked, and the amount of heat from the lower burner 36 is indirectly given from the heating space 32 through the cooking pan 10. The grill device 20 having the above-described configuration is a double-sided grill that employs an indirect heating method in which an object to be cooked on the cooking pan 10 is heated by cooking from above and below. This grill device 20 has an advantage that it is excellent in cleanability because there is no oil dripping onto the lower burner 36.

  Further, the CPU 51 of the grill device 20 determines that the average heat amount per unit time from the upper burner 35 until the predetermined time has elapsed from the start of cooking is greater than the average heat amount per unit time from the upper burner 35 after the predetermined time has elapsed. The upper burner 35 is controlled so as to be lowered. Thereby, it is possible to balance the heating by the upper burner 35 and the heating by the lower burner 36 in the initial stage of cooking. Therefore, the balance of the degree of baking of the object to be cooked can be favorably maintained. Thereby, the grill apparatus 20 can hold | maintain the balance of the baking condition of to-be-cooked material favorably, ensuring the cleaning property.

  And especially in the said embodiment, as pattern 1 of a grill control process, CPU51 ignites the upper burner 35 behind the ignition of the lower burner 36 at the time of a cooking start. Thereby, the calorie | heat amount from the upper burner 35 in the early stage of cooking can be made lower than the calorie | heat amount after that. Therefore, since it is possible to balance the heating by the upper burner 35 and the heating by the lower burner 36 at the initial stage of cooking, it is possible to maintain a good balance of the degree of baking of the cooking object.

  Further, in the above embodiment, as the pattern 2 of the grill control process, the CPU 51 continuously burns the upper burner 35 with the normal heating power until the predetermined time elapses after the ignition, or burns with the normal heating power. After that, after a predetermined time has elapsed since ignition, combustion is performed with the amplified thermal power. Thereby, the calorie | heat amount from the upper burner 35 in the early stage of cooking can be made lower than the calorie | heat amount after that. Therefore, since it is possible to balance the heating by the upper burner 35 and the heating by the lower burner 36 in the initial stage of cooking, it is possible to maintain a good balance of the degree of baking of the cooking object.

  In the above embodiment, as the grill control process pattern 3, the CPU 51 switches between the normal thermal power and the amplified thermal power a plurality of times alternately until at least a predetermined time elapses after the upper burner 35 is ignited. After a predetermined time elapses, combustion is performed with amplified thermal power. Thereby, the calorie | heat amount from the upper burner 35 in the early stage of cooking can be made lower than the calorie | heat amount from the upper burner 35 after that. Therefore, since it is possible to balance the heating by the upper burner 35 and the heating by the lower burner 36 at the initial stage of cooking, it is possible to maintain a good balance of the degree of baking of the cooking object. In addition, by changing the switching frequency (for example, the number of switching times within a predetermined time) of the amplified thermal power and the normal thermal power in the upper burner 35 in the initial stage of cooking, the amount of heat given to the cooking object from the upper burner 35 in the initial stage of cooking is finely adjusted. it can. Thereby, the cooking of the to-be-cooked object can be finely adjusted.

  In the above embodiment, as the pattern 4 of the grill control process, the CPU 51 extinguishes once after burning the upper burner 35 with normal heating power until a predetermined time elapses after ignition. Thereby, the calorie | heat amount from the upper burner 35 in the early stage of cooking can be made lower than the calorie | heat amount from the upper burner 35 after that. Therefore, since it is possible to balance the heating by the upper burner 35 and the heating by the lower burner 36 at the initial stage of cooking, it is possible to maintain a good balance of the degree of baking of the cooking object. Moreover, the upper side surface of a to-be-cooked object can be heated favorably by re-igniting after extinguishing the upper burner 35 once.

  In the above embodiment, as the pattern 5 of the grill control process, as in the pattern 4, the CPU 51 burns the lower burner 36 with normal thermal power and then extinguishes once until a predetermined time elapses after ignition. . Thereby, the calorie | heat amount from the upper burner 35 in the early stage of cooking can be made lower than the calorie | heat amount after that. Therefore, since it is possible to balance the heating by the upper burner 35 and the heating by the lower burner 36 at the initial stage of cooking, it is possible to maintain a good balance of the degree of baking of the cooking object. In addition, once the upper burner 35 is extinguished, the upper surface of the object to be cooked can be baked more reliably, because the ignition is performed again based on the temperature of the cooking pan 10.

  In addition, this invention is not limited to the said embodiment, A various change is possible. The grill device 20 of this embodiment is mounted on the table stove 1, but may be mounted on a built-in stove or may be an independent device.

  Moreover, in the said embodiment, as shown in FIG. 7, the thermal-power control mechanism part 70 provides the two bypass pipes 64 and 65 and the two electromagnetic valves 71 and 72 in the 1st gas supply pipe 62, Although the thermal power is switched in three stages, the thermal power may be switched in two stages by reducing the number of bypass pipes and the number of solenoid valves (for example, one bypass pipe and one electromagnetic valve). Further, it may be possible to adjust the heating power in more stages by further increasing the number of bypass pipes and the number of solenoid valves.

  Moreover, in the said embodiment, although the solenoid valves 71-73 are keep solenoid valves which open and close a flow path, they may be a valve which can increase / decrease a flow path area continuously, for example. When the valve is used, the heating power of the upper burner 35 can be switched gradually.

  In the above embodiment, the three-stage thermal power of the upper burner 35 and the lower burner 36 is described as the amplified thermal power as the “first thermal power” of the present invention and the normal thermal power as the “second thermal power” of the present invention. The thermal power may be “second thermal power”. In that case, normal thermal power or amplified thermal power may be set as “first thermal power”.

  In the grill control process of the above embodiment, in pattern 1, the upper burner 35 is ignited one minute after the lower burner 36 is ignited, but the ignition delay time is not limited to one minute.

  In Pattern 2, after the upper burner 35 is ignited, a normal thermal power is used until a predetermined time (for example, 5 minutes) elapses, and when the predetermined time elapses, the thermal power is switched to an amplified thermal power. You may switch to. Moreover, you may switch to amplification thermal power until predetermined time passes after ignition, and also until predetermined time passes.

  Further, in pattern 3, after the upper burner 35 is ignited, the heating power is switched alternately between the amplified thermal power and the normal thermal power until a predetermined time (for example, 5 minutes) elapses. You may switch to amplified firepower before it elapses. Moreover, you may switch to amplification thermal power until predetermined time passes after ignition, and also until predetermined time passes. Furthermore, although the time for alternately switching between the amplified thermal power and the normal thermal power is 1 minute, it may be switched in a shorter time or a longer time.

  In Pattern 4, after the upper burner 35 is ignited, it is burned with normal thermal power until a predetermined time (for example, 5 minutes) has elapsed, and then extinguished once. After the predetermined time has elapsed, re-ignition is performed. The timing to extinguish once is not limited to the above embodiment. In the above embodiment, the fire is temporarily extinguished after 3 minutes from ignition, but may be extinguished after 2 minutes or 4 minutes, for example.

  Further, in the pattern 5, the thin button type thermistor 95 is provided on the front side portion of the upper surface of the middle plate 30 of the grill cabinet 21, but there may be one or more thermistors 95. For example, two thermistors 95 may be provided apart from each other in the left-right direction at the front portion of the upper surface of the intermediate plate 30. When a plurality of thermistors 95 are provided, the average value of the measured values of each thermistor 95 may be calculated. Further, the position of the thermistor 95 is not limited to the front side portion of the upper surface of the middle plate 30, but may be any position as long as it is in contact with the bottom bottom surface of the cooking pan 10. Further, the thermistor 95 may be provided at a position other than the middle plate 30, as long as the thermistor 95 comes into contact with the cooking plate 10 when the cooking plate 10 is placed on the middle plate 30. Furthermore, instead of the temperature of the cooking dish 10, for example, the temperature of the cooking space 31 or the heating space 32 may be detected, and the lower burner 36 may be re-ignited based on the detected temperature.

  In the patterns 4 and 5, the upper burner 35 is extinguished once and then reignited. However, instead of extinguishing the fire, it may be switched to a thermal power weaker than the amplified thermal power (for example, normal thermal power or suppression thermal power). Then, you may return to amplification thermal power.

  In the above embodiment, the thermal power of the lower burner 36 is kept constant with normal thermal power, but may be kept constant with other thermal power. In addition, the heating power may be switched halfway like the upper burner 35. For example, the lower burner is set so that the average heat amount per unit time from the lower burner 36 until the predetermined time has elapsed from the start of cooking is higher than the average heat amount per unit time from the lower burner 36 after the predetermined time has elapsed. You may make it control 36 thermal power.

  For example, as in the modification of pattern 2 shown in FIG. 16, the lower burner 36 is continuously burned with amplified thermal power until 5 minutes have elapsed after ignition, and then after 5 minutes have elapsed since ignition. May be burned with normal thermal power. Thereby, the calorie | heat amount from the lower burner 36 in the early stage of cooking can be made higher than the calorie | heat amount after that. Further, in the patterns 1 to 3 to 5, the heating power of the lower burner 36 may be controlled as shown in FIG. In addition, before 5 minutes have passed since ignition, the lower burner 36 may be switched from amplified thermal power to normal thermal power.

  In the above embodiment, the “cooking start” of the present invention is when the upper burner 35 or the lower burner 36 is ignited. For example, when the pressing of the ignition switch 12 is detected, the upper burner 35 and the lower burner 36 It is a concept that includes when a flame is detected.
