JP 2010-112625 A

  In the conventional gas stove as described above, when a target cooking menu is selected from a plurality of automatic cooking menus, automatic cooking is performed on a plurality of stove parts, for example, one of two adjacent stove parts. In some cases, hot water is selected, and the fried food is selected as automatic cooking in the other stove part among the adjacent stove parts.

  In boiling water, a kettle is generally used as a cooking container, and when boiling, hot water may blow out from the spout of the kettle.

  On the other hand, in deep-fried food cooking, the temperature of the cooking oil accommodated in cooking containers, such as a pan heated by the stove part, becomes high temperature 150 degreeC or more.

  Thus, the state where the cooking container in which high temperature cooking oil is stored and the kettle in a boiling state in which hot water may blow out is not preferable, and there is room for improvement in this regard.

  The present invention has been made in view of the above points, and hot water is selected as automatic cooking in one of the adjacent stove parts, and the fried food is selected in the other stove part of the adjacent stove part. When cooking, it aims at suppressing that the cooking container in which high temperature cooking oil was accommodated, and the boiling kettle which hot water may blow out will be in the adjacent state.

  In order to achieve the above object, the present invention is configured as follows.

(1) The gas stove of the present invention controls the stove burner based on a stove burner for heating the cooking vessel, a temperature detection means for detecting the temperature of the cooking vessel, and a detected temperature detected by the temperature detection means. Control means, and cooking mode setting means for setting an automatic cooking mode including a hot water mode, the control means, when the hot water mode is set and the start of combustion of the stove burner is commanded, A gas stove that starts a water heater operation that starts combustion of a stove burner and detects a boiling state based on the temperature detected by the temperature detecting means, and performs post-processing for finishing the water heater,
The control unit includes a plurality of the burner and the temperature detection unit, and the control unit sets a predetermined temperature equal to or higher than the boiling point of water as a first predetermined temperature and a predetermined temperature lower than the boiling point of water as a second predetermined temperature. During the execution of the water heating operation in one of the stove burners, the detected temperature of the temperature detecting means corresponding to another stove burner arranged adjacent to the one stove burner is equal to or higher than the first predetermined temperature. In some cases, when the detected temperature of the temperature detecting means corresponding to the one conburner is equal to or higher than the second predetermined temperature, the thermal power reduction control for reducing the thermal power of the one conburner is executed.

  In the thermal power reduction control, the fire may be extinguished by reducing the thermal power of the burner.

  According to the present invention, during the boiling water operation of one stove burner, the detection temperature of the temperature detecting means corresponding to the other stove burner arranged adjacent to the one stove burner is equal to or higher than the boiling point of water. When it is equal to or higher than the first predetermined temperature, which is the predetermined temperature, for example, when fried food cooking is performed with another stove, and the detection temperature of the corresponding temperature detection means is higher than the boiling point of water, When the detected temperature of the temperature detecting means corresponding to one of the hot-water heaters is equal to or higher than a second predetermined temperature lower than the boiling point of water, the thermal power reduction control for reducing the thermal power of the one hot-burner is executed. Therefore, it is suppressed that the cooking container heated with one stove burner, generally the water accommodated in the kettle boiled.

  Thereby, it can suppress that the cooking container in which high temperature cooking oil was accommodated, and the boiling kettle which hot water may blow out will be in the adjacent state.

  (2) In a preferred embodiment of the present invention, the control means sets a predetermined temperature equal to or lower than the second predetermined temperature as a third predetermined temperature, and the other stove during the execution of the hot water operation in the one stove burner. When the detected temperature of the temperature detecting means corresponding to the burner is equal to or higher than the first predetermined temperature, and when the detected temperature of the temperature detecting means corresponding to the one burner is less than the third predetermined temperature, The heating power of one stove burner is controlled to the heating power at the start of the water heating operation.

  According to this embodiment, during the water heating operation of one stove burner, the detection temperature of the temperature detecting means corresponding to the other stove burner arranged adjacent to the one stove burner is equal to or higher than the boiling point of water. If the detected temperature of the temperature detecting means corresponding to one combustor is lower than the third predetermined temperature, the heating power at the start of the water heating operation is controlled. Since the hot water operation is started by the above-described stove burner and the hot water operation is continued until the temperature detected by the corresponding temperature detecting means reaches the third predetermined temperature which is lower than the second predetermined temperature, the usability is not impaired.

  Then, when the detected temperature of the temperature detecting means corresponding to the one burner becomes equal to or higher than the second predetermined temperature, thermal power reduction control is executed, and the detected temperature of the temperature detecting means is lowered by this thermal power reduction control, and the third When the temperature is lower than the predetermined temperature, the heating power of the one burner is controlled to the heating power at the start of the water heating operation, that is, the heating power is returned to the original heating power. When the temperature exceeds the temperature, the thermal power reduction control is executed again. As a result, the temperature detected by the temperature detecting means corresponding to the one cooker during the water heater operation, that is, the temperature of the cooking container heated by the one cooker is in the range between the second predetermined temperature and the third predetermined temperature. It is maintained at a nearby temperature.

  Thereby, for example, when fried food cooking of the other stove burner is finished and the detected temperature of the corresponding temperature detecting means becomes lower than the first predetermined temperature, without performing the heating power reduction control of one stove burner, The hot water maintained at the above temperature can be quickly boiled to terminate the hot water operation.

  (3) In another embodiment of the present invention, the cooking mode setting means can set the cooking mode for each of the burners, and the control means can detect the temperature detected by the temperature detecting means and the cooking mode. Based on the cooking mode set by the setting means, the corresponding cooker is controlled to perform automatic cooking, and the hot water operation in the one cooker and the automatic cooking in the other cooker Can be executed simultaneously.

  According to this embodiment, it is possible to simultaneously perform a water heater operation by one stove burner and automatic cooking by another stove burner, for example, deep-fried food cooking.

  (4) In a preferred embodiment of the present invention, it is provided with a notification means, and the control means controls the notification means to notify the fact while the heating power reduction control is being executed.

  According to this embodiment, the user is not confused because the fact is notified during the execution of the thermal power reduction control.

  According to the present invention, the temperature detected by the temperature detecting means corresponding to the other stove burner arranged adjacent to the one stove burner is equal to or higher than the boiling point of water during the water boiling operation of the one stove burner. When the temperature is equal to or higher than the first predetermined temperature, the detected temperature of the temperature detecting means corresponding to the one burner during the boiling water operation is equal to or higher than the second predetermined temperature, which is a predetermined temperature lower than the boiling point of water. Sometimes, the thermal power reduction control for reducing the thermal power of the one stove burner is executed, so that the cooking container heated by the one stove burner, generally, the water contained in the kettle is suppressed from boiling. . Thereby, it can suppress that the cooking container in which high temperature cooking oil was accommodated, and the boiling kettle which hot water may blow out will be in the adjacent state.

FIG. 6 is a schematic cross-sectional view of the gas valve block 6 that supplies and shuts off the fuel gas to each burner. FIG. 6 shows a state in which a main valve described later is opened. The gas valve block 6 has the same specifications as the stove burner 31 and the grill burner.

  In the gas valve block 6, the instrument plug body 60 is provided with an internal gas flow path 61, and an introduction port 61 a that is an upstream end of the gas flow path 61 and a discharge port 61 b that is a downstream end. The internal gas flow path 61 is provided with a valve hole for the safety valve 62 and a valve hole for the main valve 63 from the upstream side. On the downstream side of the valve hole for the main valve 63, a large-fire channel 61c and a small-fire channel 61d are provided in parallel, and the large-fire channel 61c is a latch for switching between large and small thermal powers. A valve hole for the solenoid valve LB1 is provided, and a valve hole for the latch solenoid valve LB2 is provided in the small fire channel 61d.

  Incidentally, when the fire extinguishing button 14 is operated when the cooking container is not detected by the container detecting means 25 described above, the latch type electromagnetic valve LB1 and the latch type electromagnetic valve LB2 are closed by the control unit, and heating is performed. The container detection control is performed so as not to start, and when the cooking container is not placed on the virtues 21, no flame is formed on the stove burner 31.

  Further, the gas flow path 61 is provided with a bypass flow path BP that bypasses the portion where the latch type electromagnetic valve LB1 and the latch type electromagnetic valve LB2 are provided, and a bypass orifice of1 is provided in the bypass flow path BP. is there. The bypass orifice of1 is provided to share the gas valve block 6 among a plurality of models, and may be opened when the gas valve block 6 is used for application to other models. The bypass orifice of1 is closed by a closing body (not shown).

  When the thermal power adjustment lever 15 is set to a position between medium and large fires, the thermal power of the conoburner 31 depends on the combination of opening and closing of the latching solenoid valve LB1 and the latching solenoid valve LB2. Adjustment control is performed by the control unit.

  The downstream side of the valve hole for the flow control valve 65 leads to the outlet for supplying gas to the burner 31.

  The instrument plug main body 60 is equipped with a slider 66 that is movable in the front-rear direction as an operating member that operates in conjunction with the point fire extinguishing button 14 and is biased forward by a spring. The slider 66 moves backward against the spring biasing force when the front end surface is pressed rearward by the point fire button 14.

  The point-extinguishing button 14 is provided so as to be able to move back and forth. The portion above the portion pressed by the finger of the point-extinguishing button 14 is pivotally supported on the stove body side and the portion pressed by the finger moves back and forth. The front end surface of the slider 66 is pressed backward.

  As shown in FIGS. 7A to 7C, the slider 66 has a well-structured heart-shaped cam mechanism 90 provided in the lower part of the gas valve block 6 and has a “stop position” (a) at the front, The “ignition position” (b) and “combustion position” (c) slightly ahead of it can be switched and held. That is, as shown in FIG. 7, when the fire extinguishing button 14 is largely pushed, the slider 66 moves from the “stop position” (a) to the “ignition position” (b) against the spring biasing force. When the pushing operation of the fire extinguishing button 14 is released, the urging is returned slightly forward from the “ignition position” (b), and is stably held at the “burning position” (c). Then, after the point-extinguishing button 14 is pushed largely again, when the pushing operation is released, the slider 66 is once moved backward from the “combustion position” (c) and then moved forward by the spring biasing force to “stop”. The position is returned to (a).

  Further, the instrument plug main body 60 incorporates a valve rod 67 that moves forward and backward as the slider 66 advances and retracts so as to be spring-biased forward, and when the slider 66 is in the “stop position” (a), The rear end and the front end of the valve rod 67 are opposed to each other with a gap. That is, the stroke until the slider 66 in the “stop position” (a) contacts the front end of the valve rod 67 is the “play stroke” s that maintains the state where the main valve 63 is closed.

  The distal end side of the valve rod 67 is inserted into the gas flow path 61, and the distal end portion thereof is inserted through the valve hole for the main valve 63 and the valve hole for the safety valve 62 from the rear side, that is, from the downstream side to the upstream side. Has been. When the slider 66 is switched from the “stop position” (a) to the “combustion position” (c), the valve rod 67 temporarily moves backward to the “ignition position” (b) behind the “combustion position” (c). To the “combustion position” (c), and when moving to this “combustion position” (c), the valve body of the safety valve 62 closing the valve hole for the safety valve 62 from the upstream side is moved upstream. The valve hole for the safety valve 62 is opened by moving. The safety valve 62 is composed of an electromagnetic valve, and the valve body for the safety valve 62 is closed from the rear when the valve body moves forward, that is, downstream, and the valve hole for the safety valve 62 that is moved backward, that is, upstream. Is released.

  The safety valve 62 is kept open by the control unit only when a flame is detected by the ignition detection device 24, and when the flame is no longer detected, the maintenance of the open state by the control unit is stopped and closed. As a result, the fuel gas can be prevented from flowing out when it disappears due to boiling or wind and the flame of the ignition detection device 24 is no longer detected. In addition, when the temperature of the lower surface of the cooking container detected by the temperature sensor 26 reaches a predetermined temperature (for example, 270 ° C.), the control unit determines that an abnormality such as burning or scorching has occurred, and the safety valve 62 is closed. In this manner, the safety valve 62, the ignition detection device 24, and the temperature sensor 26 constitute an abnormality detection means.

  In the middle of the valve rod 67, a main valve body for opening and closing a valve hole for the main valve 63 is provided. As shown in FIG. 7A, when the slider 66 is in the “stop position” (a), the valve rod 67 is in a free state separated from the slider 66, and the main valve body is a valve for the main valve 63. Energize and close the hole from the rear. Further, as shown in FIG. 7B, when the slider 66 is in the “ignition position” (b), the valve rod 67 is largely abutted and moved rearward by the slider 66, and the main valve body is used for the main valve 63. The valve hole for the main valve 63 is greatly opened at a position larger rearward than the valve hole. Further, as shown in FIG. 7C, when the slider 66 is in the “combustion position” (c), the valve rod 67 is slightly abutted and moved backward by the slider 66 so that the main valve element is used for the main valve 63. The valve hole for the main valve 63 is opened at a predetermined opening, which is located behind the valve hole by a predetermined amount.

  The opening of the valve hole for the flow rate control valve 65 is freely adjusted by the movement of the heating power adjustment needle 65a in the front-rear direction. The opening of the needle 65a is adjusted by moving the thermal power adjustment lever 15 to the left and right, and the needle 65a is adjusted so that the amount of fuel gas supplied increases as the thermal power adjustment lever 15 moves to the right.

  An appliance plug switch 91 and an igniter switch 92 that are turned ON / OFF depending on the position of the point fire button 14 or the slider 66 are provided. The appliance plug switch 91 is OFF when the slider 66 is positioned at the front “stop position” (a), and is positioned at the rear “combustion position” (c) and “ignition position” (b). It becomes ON. The igniter switch 92 is turned on only when the slider 66 is positioned at the last “ignition position” (b), and is turned off at a position ahead of it.

  In order to ignite the burner 31 and the grill burner, the point fire extinguishing button 14 is pushed to move the slider 66 backward from the “stop position” (a) to the “ignition position” (b). The valve rod 67 retracted together with the slider 66 opens the safety valve 62 and the main valve 63, and the fuel gas is supplied to the stove burner 31 and the grill burner. Further, when the slider 66 moves backward, the instrument plug switch 91 is turned on, the power supply to the control unit is turned on, and the control unit starts operating. When the safety valve 62 starts to open, the igniter switch 92 is turned on by the slider 66 retracted to the “ignition position” (b), and the control unit operates the igniter of the ignition device to discharge the ignition plug. The burner ignition is started.

  When ignition to the burner by the ignition operation is detected by the ignition detection device 24, the control unit holds the safety valve 62 in an open state and continues ignition of the burner.

  Thereafter, when the pressing operation of the point-extinguishing button 14 is released, the slider 66 is energized and returned to the “combustion position” (c) slightly ahead of the “ignition position” (b) and is stably held, and the burner continues to be in the combustion state. Maintained.

  When the point-extinguishing button 14 is pushed and heating is started, a desired heating power can be obtained by operating the heating power adjustment lever 15. It should be noted that the heating power adjusting lever 15 of the stove section 2a provided with the left-side stove burner 31 is operated by operating the operation section of the stove section 2a so that the heating power is moved to the middle heating power side in conjunction with the operation of the operation section. It is designed to move and has a moderate heating power when ignited.

  Further, when the fire extinguishing button 14 is largely pushed again in a state where the burner is burning and then the pushing is released, the slider 66 once moves backward from the “burning position” (c), and then the “stopping position” ( The energization returns to a), the main valve 63 is closed, and the burner is extinguished.

  When the sliders 66 of all the point fire extinguishing buttons 14 are set to the “stop position” (a), all the main valves 63 of each burner are closed and extinguished, and all the instrument plug switches 91 of each burner are turned off. Thus, the safety valve 62 of each burner is closed, and the control unit stops outputting the power holding signal for maintaining the power supply state, thereby terminating the power supply to the control unit.

  As shown in FIG. 2, the cooking setting unit 7 for the stove is a cooking mode setting means for selecting and setting an automatic cooking menu, and a fried food switch 73 for instructing a fried food mode, and a rice cooking switch 74 for instructing a rice cooking mode. A hot water switch 75 for instructing the hot water mode is provided. In addition, left and right stove part selection switches 76 and 77 that are operated to select the left and right stove parts 2a and 2a, respectively, are provided as stove parts that perform automatic cooking.

  The fried food switch 73 is configured to select and set a plurality of set target temperatures such as 200 ° C., 180 ° C., and 160 ° C. each time the button is pressed. The stove cooking setting section 7 is provided with temperature display lamps 73a to 73c for displaying the temperature of the fried food cooking at each set temperature (200 ° C., 180 ° C., 160 ° C.) by lighting.

  The rice cooking switch 74 is configured so that rice cooking can be selected and set with rice and porridge each time it is pushed. The stove cooking setting section 7 is provided with a rice display lamp 74a for displaying that the set rice cooking is rice by lighting, and a rice bowl display lamp 74b for displaying that it is rice porridge by lighting. Yes.

  The hot water switch 75 is configured to be able to select and set the automatic fire extinguishing mode and the 5-minute heat retention mode each time it is pressed. The automatic fire extinguishing mode is a mode in which heating is performed with a large heating power until the boiling is detected, and the fire is immediately extinguished after the boiling is detected. Is a mode in which the power is reduced to a small heating power and then heated for 5 minutes and then extinguished. The cooking setting unit 7 for the stove is lit to indicate that the set mode is the automatic fire extinguishing mode by lighting, and to turn on that the set mode is the 5-minute heat retention mode. A 5-minute heat display lamp 75b for displaying is provided.

  The stove cooking setting unit 7 is provided with a timer input unit 71 including a plus switch 71a and a minus switch 71b for setting the cooking time, and a timer display unit 72.

  3 includes a timer input unit 81 and a timer display unit 82 including a plus switch 81a and a minus switch 81b for setting cooking time.

  The control unit ignites and burns the stove burner 31 by an ignition command from the fire extinguishing button 14 when each cooking of fried food, rice cooking, or kettle is set in the cooking setting unit 7 for the stove. In a state, based on the setting information of the cooking setting part 7 for a stove, each cooking of fried food, rice cooking, or kettle is performed. In each automatic cooking, the control unit performs a process of operating the latch type solenoid valve LB1 and the latch type solenoid valve LB2 for switching between the large thermal power and the small thermal power in order to adjust the thermal power of the stove burner 31.

  Next, in the automatic cooking performed by the control unit, the water heating operation and the automatic temperature control will be described in detail.

  First, the hot water operation will be described.

  The boiling water operation is basically a process for executing a post-processing for finishing a water heater when a boiling state is detected based on the temperature detected by the temperature sensor 26. The post-processing for finishing a water heater corresponds to an automatic fire extinguishing mode. And a process corresponding to the 5-minute heat retention mode.

  The detection of the boiling state will be described. In the present embodiment, after the combustion of the combustor 31 is started, the measurement ends when the temperature detected by the temperature sensor 26 rises to the measurement start temperature (for example, 85 ° C.). The elapsed time until the temperature rises (for example, 90 ° C.) is obtained as the temperature rise time, and the boiling time is determined by multiplying the temperature rise time by a predetermined coefficient, for example, “1”.

  After that, that is, after the boiling discrimination time is determined as described above, when the unit temperature rise time required for the temperature detected by the temperature sensor 26 to rise by 1 ° C. exceeds the boiling discrimination time, the boiling state is reached. It is comprised so that it may determine.

  Next, automatic temperature control will be described.

  For example, fried food cooking will be described as the automatic temperature adjustment control.

  The deep-fried food switch 73 is pressed to select and set a desired target temperature from 200 ° C., 180 ° C., and 160 ° C., and the combustor 31 is ignited and burned by an ignition command from the point-off button 14. Then, the control unit adjusts the heating power of the burner 31 so that the temperature detected by the temperature sensor 26 becomes the set target temperature, and the latching solenoid valve LB1 for switching between the large heating power and the small heating power, and the latching type. Automatic temperature control is performed to perform processing for operating the electromagnetic valve LB2.

  In other words, when the control unit executes the automatic temperature control, when the temperature detected by the temperature sensor 26 is lower than the set target temperature, the heating power of the burner 31 is increased, and when the temperature detected by the temperature sensor 26 is higher than the set target temperature. The firepower of the stove burner 31 will be reduced.

  In the present embodiment, as described above, the stove unit 2a that performs automatic cooking can be selected by operating the left and right stove unit selection switches 76 and 77, and automatic cooking is simultaneously performed by the left and right stove units 2a and 2a. Can be executed.

  Accordingly, when one of the left and right side stove burners 31, for example, the left side stove burner 31 is performing a boiling operation as automatic cooking, at the same time, the other side stove burner 31, for example, the right side stove burner 31. In the gas stove, automatic temperature control such as fried food and rice cooking can be executed at the same time, and the gas stove is easy to use.

  Further, in the present embodiment, when one of the left and right side stove burners 31, for example, the left side stove burner 31, is performing a water heating operation, it is disposed adjacent to the one side stove burner 31. When the detected temperature of the temperature sensor 26 corresponding to the other combustor 31, for example, the right-hand side combustor 31, is equal to or higher than a first predetermined temperature (eg, 103 ° C.) set to be equal to or higher than the boiling point of water, The control is performed as follows.

  That is, when the detected temperature of the temperature sensor 26 corresponding to the one conburner 31 is lower than a second predetermined temperature (for example, 95 ° C.) set to be lower than the boiling point of water, the control unit The hot water operation at 31 is continued.

  In addition, when the temperature detected by the temperature sensor 26 corresponding to the one burner 31 is equal to or higher than the second predetermined temperature (for example, 95 ° C.), the heating power reduction control for reducing the heating power of the one burner 31 is executed. To do. In the present embodiment, the thermal power is reduced to the minimum thermal power set as the one conburner 31.

  With this thermal power reduction control, when the temperature detected by the temperature sensor 26 corresponding to one of the burners is less than the second predetermined temperature (for example, 95 ° C.), the heating power of the one burner 31 is started to be heated. Perform return control to return to the original large firepower of the time.

  As a result, the temperature detected by the temperature sensor 26 corresponding to the one burner is maintained in the vicinity of the second predetermined temperature (for example, 95 ° C.).

  As described above, the thermal power reduction control and the return control in the one conburner 31 are performed by detecting the temperature detected by the temperature sensor 26 corresponding to the other conburner 31 disposed adjacent to the one conburner 31. This is control when the temperature is equal to or higher than the first predetermined temperature (eg, 103 ° C.) set to be equal to or higher than the boiling point of water.

  Therefore, when the detected temperature of the temperature sensor 26 corresponding to the other conburner 31 disposed adjacent to the one conburner 31 becomes less than the first predetermined temperature, the control in the one conburner 31 is performed. When returning to the original control and continuing the water heating operation and the automatic fire extinguishing mode is set, after heating with a large heating power until the boiling is detected, the fire is immediately extinguished after the boiling is detected, and the 5-minute heat retention mode Is set, the heating is performed with a large heating power until the boiling is detected, then the boiling is detected, the heating power is decreased to a small heating power, the heating is performed for 5 minutes, and then the fire is extinguished.

  As described above, in the present embodiment, the temperature detected by the temperature sensor 26 corresponding to the other stove burner 31 is equal to or higher than a first predetermined temperature (eg, 103 ° C.) that is a predetermined temperature equal to or higher than the boiling point of water. However, when the detected temperature of the temperature sensor 26 corresponding to the one conburner 31 is lower than a second predetermined temperature (for example, 95 ° C.) that is a predetermined temperature lower than the boiling point of water, that is, the one conburner. When the cooking container heated at 31, generally, the water contained in the kettle is before boiling, the hot water boiling operation in the one stove burner 31 is continued, so the usability is not impaired.

  Further, when the temperature detected by the temperature sensor 26 corresponding to the other conburner 31 is equal to or higher than a first predetermined temperature (for example, 103 ° C.) that is a predetermined temperature equal to or higher than the boiling point of water, When the temperature detected by the corresponding temperature sensor 26 is equal to or higher than a second predetermined temperature (for example, 95 ° C.), which is a predetermined temperature lower than the boiling point of water, that is, stored in the kettle heated by the one burner 31. When there is a high probability that the water will boil, the thermal power reduction control for reducing the thermal power of the one stove burner 31 is executed, so that one of the left and right stove parts is selected as automatic cooking in one of the stove parts. When fried food is selected as automatic cooking in the other stove part, the cooking container containing hot cooking oil and the boiling state that hot water may blow out And kettle can be prevented from becoming a state of adjoining.

  FIG. 8 illustrates a time-series relationship in a case where a hot water boiling operation is performed in the one stove burner 31 and deep-fried food cooking is performed in the other stove burner 31 by automatic temperature control control.

  In the boiling water operation by one of the stove burners 31, the temperature detected by the temperature sensor 26 corresponding to the other stove burner 31 is equal to or higher than a first predetermined temperature (eg, 103 ° C.). As described above, the heating power reduction control and the return control are repeated, the boiling state is not detected, and the water boiling operation proceeds in parallel with fried food cooking.

  FIG. 4B shows an example in which fried food cooking is started in the other cono burner 31 during the water boiling operation by one cono burner 31.

  In this example, before the temperature detected by the temperature sensor 26 corresponding to the other combustor 31 becomes equal to or higher than a first predetermined temperature (for example, 103 ° C.), that is, before the heating power reduction control of the one conburner 31 is performed. In addition, the boiling state is detected, and the water heating operation is finished.

  FIG. 3C shows an example in which the water heating operation by one of the stove burners 31 is started after the fried food cooking by the other stove burner 31 is completed.
