The device structure, flowcharts, and the like described below are merely illustrative examples, and are not intended to limit the present invention unless otherwise specified. The drawings are used to explain technical features that can be adopted by the present invention. The following explanation uses the left, right, front, back, top and bottom indicated by arrows in the figure.

-First embodiment-
The structure of the gas stove 1 will be described with reference to FIGS. As shown in FIG. 1, the gas stove 1 is a built-in stove. The gas stove 1 includes a housing 2 and a top plate 3. A top plate 3 is installed on the top of the housing 2. In addition, the gas stove 1 which combined the housing | casing 2 and the top plate 3 is equivalent to the "instrument" of this invention. In the top 3, a right stove burner 4 is provided on the right side, and a left stove burner 5 is provided on the left side. The right stove burner 4 and the left stove burner 5 have the same specifications. A sensor assembly 20 that can contact the bottom of the pan is provided at the center of each of the right and left stove burners 4 and 5. The sensor assembly 20 is provided so as to be able to move in and out in the vertical direction, and stores the thermistor 40 (see FIG. 3). The thermistor 40 detects the temperature of the cooking pan through the sensor assembly 20. A thermocouple 50 (see FIG. 3) for detecting a misfire and an igniter 60 (see FIG. 3) for igniting are provided in the vicinity of each of the right and left burners 4 and 5. An exhaust port 7 of a grill box (not shown) installed in the gas stove 1 is provided at the rear portion of the top plate 3.

  On the top surface of the top plate 3, a window 31 is provided in the vicinity of the right front corner, and a window 32 is provided in the left front corner. The window portions 31 and 32 are transparent regions formed in a circular shape, and pass through the lower side of the top plate 3 when viewed from above. Below the window portion 31, a right sensor 77A supported on the upper right side inside the housing 2 is disposed. Below the window 32, a left sensor 77B supported on the upper left side inside the housing 2 is disposed. The right sensor 77A and the left sensor 77B are optical sensors that receive a reflected wave reflected from a foreign object by a detection wave transmitted from the transmission unit and measure the distance to the foreign object by applying a triangulation method. It is a distance sensor. The right sensor 77A and the left sensor 77B output the measured distance to the foreign object as a distance signal toward a sensor input circuit 87 (see FIG. 3) described later.

  As shown in FIG. 2, the right sensor 77 </ b> A outputs a detection wave toward the upper right side of the top plate 3 through the window portion 31, and the wall of the kitchen when the kitchen wall is disposed on the right side of the gas stove 1. Perform detection. The left sensor 77B outputs a detection wave toward the upper left of the top plate 3 through the window 32, and detects the wall when the kitchen wall is disposed on the left side of the gas stove 1. In the example shown in FIG. 2, the kitchen wall 10 is located on the left side of the gas stove 1. In this case, the left sensor 77B detects the wall 10 located within a predetermined distance range on the left side of the gas stove 1.

  As shown in FIG. 1, a grill door 8 is provided in the approximate center of the front surface of the gas stove 1. The grill door 8 is movably supported on the front side, and opens and closes a front opening of a grill box (not shown) provided inside the gas stove 1. A grill burner (not shown) is provided in the grill cabinet. A thermocouple 50 and an igniter 60 are also provided in the vicinity of the grill burner. In the area on the right side of the grill door 8, operation buttons 11 and 12 having a circular shape in front view are arranged in a horizontal row in order from the right side to the left side. A power button 25 is provided immediately above the operation button 11. In the left region of the grill door 8, the same circular operation button 13 is provided at the same height as the operation buttons 11 and 12.

  The operation button 11 is pressed to ignite and extinguish the right burner 4, the operation button 12 is a grill burner, and the operation button 13 is lit to extinguish and extinguish the left burner 5. The operation buttons 11 to 13 are substantially flush with the front surface of the gas stove 1 when the corresponding burner is extinguished (see FIG. 1). When pressed for ignition, the control circuit 70 described later performs ignition processing on the corresponding burner, and the operation buttons 11 to 13 are moved from the front of the gas stove 1 by a known push-push mechanism (not shown). It protrudes in a substantially cylindrical shape toward the front, and can be rotated in the protruding state. When the operation buttons 11 to 13 are rotated, the control circuit 70 adjusts the gas supply amount to the corresponding burner so that the gas amount corresponds to the rotation operation amount.

  Three gas amount adjusting devices 30 (see FIG. 3) are provided inside the gas stove 1. The gas amount adjusting device 30 adjusts the gas supply amount to the corresponding right stove burner 4, left stove burner 5, and grill burner. The gas amount adjusting device 30 includes a valve mechanism 36 and a motor 37. The valve mechanism 36 includes various valves such as a needle valve and an electromagnetic valve that adjust the amount of gas flowing through the gas flow path, for example. The motor 37 drives the valve of the valve mechanism part 36, and the gas flow volume which flows through a gas flow path is adjusted. The drive of the motor 37 is controlled by the control circuit 70.

  When the operation buttons 11 to 13 are pushed and protruded toward the front, the control circuit 70 energizes the motor 37 of the gas amount adjusting device 30. As a result, the valve mechanism 36 is driven and the gas flow path is opened, whereby gas is supplied to the corresponding burner. At the same time, the control circuit 70 activates the corresponding igniter 60 to ignite the corresponding burner. Then, according to the rotation direction and rotation angle of the operation buttons 11 to 13, the control circuit 70 rotates the motor 37 in the forward and reverse directions to adjust the opening degree of the valve in the valve mechanism unit 36. Thereby, the thermal power of the corresponding burner is adjusted by adjusting the amount of gas flowing through the gas flow path. Further, when the operation buttons 11 to 13 are pushed into the gas stove 1 and accommodated, the control circuit 70 rotates the motor 37 in the reverse direction. Thereby, the valve of the valve mechanism part 36 is driven in the reverse direction, and the gas flow path is closed, whereby the supply of gas to the corresponding burner is shut off. In the present embodiment, for convenience of explanation, the right stove burner 4, the left stove burner 5, and the grill burner may be referred to as the right stove 4, the left stove 5, and the grill, respectively.

  The electrical configuration of the gas stove 1 will be described with reference to FIG. In the following description, the right stove burner 4, the left stove burner 5, and the grill burner are referred to as the right stove 4, the left stove 5, and the grill, respectively. The gas stove 1 includes a control circuit 70. The control circuit 70 includes a CPU 71, a ROM 72, a RAM 73, a nonvolatile memory 74, and the like. The CPU 71 performs overall control of various operations of the gas stove 1. The ROM 72 stores various programs including a stove heating power setting program, for example. The stove heating power setting program executes a stove heating power setting process (see FIG. 5) described later. The RAM 73 temporarily stores various information. The nonvolatile memory 74 stores flag information such as a right side wall flag, a left side wall flag, and a restriction flag, burner thermal power information described later, stove thermal power setting information, and the like. The right wall flag is set to 1 when the right sensor 77A detects a kitchen wall within a predetermined distance on the right side of the gas stove 1, and is set to 0 when no wall is detected. The left side wall flag is set to 1 when the left sensor 77B detects a kitchen wall within a predetermined distance on the left side of the gas stove 1, and is set to 0 when no wall is detected. The restriction flag is set to 0 when the ignition of the corresponding burner is permitted and 1 when the ignition is restricted in response to pressing of the operation buttons 11 to 13.

  The control circuit 70 includes a power supply circuit 81, a thermistor input circuit 82, a thermocouple input circuit 83, an igniter circuit 84, an operation panel 24, a motor control circuit 85, a sensor input circuit 87, a buzzer circuit 88, a sensor 19 and the like. Each is connected. When the power button 25 is pressed by the user, the power supply circuit 81 steps down the AC (for example, 100V) supplied from the power supply 23 to a direct current (for example, 5V) to rectify and supply power to various circuits. Therefore, the power source of the gas stove 1 is turned on. When the power button 25 is pressed again by the user, the power supply circuit 81 cuts off power supply to various circuits. Therefore, the power source of the gas stove 1 is turned off.

  The thermistor input circuit 82 inputs a detection signal from the thermistor 40 stored in the sensor assembly 20 provided in each burner to the control circuit 70. The thermocouple input circuit 83 inputs the detection value (signal corresponding to the thermoelectromotive force) from the thermocouple 50 to the control circuit 70. The igniter circuit 84 drives the igniter 60 of the corresponding burner based on the control signal from the CPU 71. The operation panel 24 is accommodated in the lower right portion of the front panel of the gas stove 1, and is pulled out to the near side by pushing in this portion. The operation panel 24 receives input such as timer setting by the user, selection of thermal power control according to the cooking menu, and the like, and inputs the input signal to the control circuit 70. As will be described later, the operation panel 24 of the present embodiment can also accept a predetermined operation for executing the stove heating power setting process of FIG. The motor control circuit 85 controls the driving of the motors 37 of the three gas amount adjusting devices 30 based on the control signal from the CPU 71, respectively.

  The sensor input circuit 87 inputs detection signals from the right sensor 77A and the left sensor 77B to the control circuit 70. The buzzer circuit 88 drives the piezoelectric buzzer 78 based on a control signal from the CPU 71. The sensor 19 is provided in each of the operation buttons 11 to 13, detects the rotation direction and rotation angle of the operation buttons 11 to 13, and inputs the detection signal to the control circuit 70. Based on the detection signal from the sensor 19, the CPU 71 rotates the output shaft of the motor 37 to drive the valve mechanism 36 so as to correspond to the rotation direction and rotation angle of the operation buttons 11 to 13. Thereby, the gas quantity which flows through a gas flow path is adjusted, and the thermal power of a corresponding burner is adjusted.

  The gas amount adjusting device 30 is provided with a position meter 35. The position meter 35 detects the rotation angle of the output shaft of the motor 37 and inputs the detection signal to the control circuit 70. The CPU 71 recognizes the rotation angle of the output shaft of the motor 37 based on the detection signal from the position meter 35. The CPU 71 can identify the corresponding burner thermal power based on the recognized rotation angle of the output shaft of the motor 37 and burner thermal power information described later. The gas stove 1 may include a communication unit that can communicate with an external device wirelessly or by wire. In that case, the gas stove 1 can receive various programs and data from the external device via the communication unit, and can update the control content, for example.

  With reference to FIG. 4, the thermal power adjustable range in the gas amount adjusting device 30 and the thermal power adjustable range set for the right stove 4 and the left stove 5 will be described. The range in which the thermal power can be adjusted means a range in which the corresponding burner thermal power can be adjusted in the gas amount adjusting device 30. The thermal power adjustment range means a burner thermal power range that can be adjusted in the right stove 4 and the left stove 5 among the thermal power adjustable range. In each gas amount adjusting device 30 of the right stove 4 and the left stove 5, the range in which the heat power can be adjusted is divided into six stages of 1 to 6. 1 to 6 are thermal power setting positions at which specific thermal power can be set. Among them, the range of 2 to 6 is set to the strong heating power range, and the range of 1 to 5 is set to the weak heating power range. The strong heating power range and the weak heating power range are heating power adjustment ranges set for the right stove 4 and the left stove, respectively.

  In the gas amount adjusting device 30, the rotation angle of the motor 37 is assigned to each of the high thermal power range and the low thermal power range. Thereby, the CPU 71 can identify the corresponding burner heating power based on the rotation angle of the output shaft of the motor 37. In the gas stove 1, information in which the rotation angle of the output shaft of the motor 37 is associated with the burner thermal power is stored in the nonvolatile memory 74 as burner thermal power information. The maximum output of the gas stove 1 is set in advance, and when one of the right stove 4 and the left stove 5 is set in the high heat power range, the other is set in the low heat power range. Note that it is determined in the stove heating power setting process, which will be described later, whether the heating power adjustment range of the strong heating power range or the weak heating power range is set for the right cooking stove 4 and the left cooking stove 5.

  The stove heating power setting process will be described with reference to FIGS. When the installer installs the gas stove 1 on the counter top of the kitchen, for example, when the gas stove 1 is activated by the power button 25 and a predetermined operation is executed on the operation panel 24, the CPU 71 reads the stove heating power setting program from the ROM 72 and performs this processing. Execute.

  As shown in FIG. 5, the CPU 71 executes an initial process (S1). In the initial process, the CPU 71 sets the right side wall flag to 0 and the left side wall flag to 1, for example. That is, in this embodiment, the state (refer FIG. 2) by which the kitchen wall 10 was detected on the left side of the gas stove 1 is made into a default. Further, the CPU 71 sets the restriction flag to 1 during the initial process.

  Next, the CPU 71 executes wall detection processing (S2). The wall detection process is a process of detecting a kitchen wall around the gas stove 1 installed on the countertop of the kitchen. Specific processing of this processing will be described later. Next, the CPU 71 executes a thermal power adjustment range setting process (S3). The thermal power adjustment range setting process is a process of setting the respective thermal power adjustment ranges of the right stove 4 and the left stove 5 based on the position of the kitchen wall detected by the wall detection process. Specific processing of this processing will be described later. In this way, the CPU 71 ends the stove heating power setting process.

  The wall detection process will be described with reference to FIG. The CPU 71 acquires a distance signal from the right sensor 77A via the sensor input circuit 87 (S11). The CPU 71 may acquire a distance signal from the right sensor 77A, for example, a predetermined number of times (for example, four times). The CPU 71 determines whether the distance cannot be determined from the acquired predetermined number of distance signals (S12). For example, when the difference between the maximum value and the minimum value of the distances corresponding to the acquired predetermined number of distance signals is equal to or greater than the threshold value, the CPU 71 may determine that the distance signal variation is large and the distance determination is impossible. When the difference between the maximum value and the minimum value is less than the threshold value, it is considered that the variation in the distance signal is considered to be small and the distance can be determined. If it is determined that the distance cannot be determined (S12: YES), the CPU 71 determines that there is no wall on the right side of the gas stove 1, and sets the right side wall flag to 0 (S16).

  On the other hand, if it is determined that the distance can be determined (S12: NO), the CPU 71 calculates an average value of the acquired predetermined number of distances and specifies the distance to the foreign object (wall) (S13). CPU71 judges whether the specified distance is below a predetermined distance (S14). When the specified distance is larger than the predetermined distance (S14: NO), it is determined that there is no wall in the range of the predetermined distance on the right side of the gas stove 1, and the right side wall flag is set to 0 (S16). On the contrary, when the specified distance is equal to or smaller than the predetermined distance (S14: YES), the wall is located on the right side of the gas stove 1, and therefore the CPU 71 sets the right side wall flag to 1 (S15).

  Next, the CPU 71 obtains a distance signal from the left sensor 77B via the sensor input circuit 87, similarly to the right sensor 77A (S18). The CPU 71 may acquire a distance signal from the left sensor 77B, for example, a predetermined number of times (for example, four times). The CPU 71 determines whether the distance cannot be determined from the acquired predetermined number of distance signals (S19). The method for determining whether the distance can be determined is as described above. If it is determined that the distance cannot be determined (S19: YES), the CPU 71 determines that there is no wall on the left side of the gas stove 1, and sets the left side wall flag to 0 (S23).

  On the other hand, if it is determined that the distance can be determined (S19: NO), the CPU 71 calculates an average value of the acquired predetermined number of distances and specifies the distance to the foreign object (wall) (S20). CPU71 judges whether the specified distance is below a predetermined distance (S21). When the specified distance is larger than the predetermined distance (S21: NO), it is determined that there is no wall on the left side of the gas stove 1, and the left side wall flag is set to 0 (S23). On the contrary, when the specified distance is equal to or smaller than the predetermined distance (S21: YES), the wall is located on the left side of the gas stove 1, and therefore the CPU 71 sets the left side wall flag to 1 (S22). In this way, the CPU 71 ends this process, and advances the process to S3 in FIG.

The heating power adjustment range setting process will be described with reference to FIG. This process is a process of setting the respective heating power adjustment ranges of the right stove 4 and the left stove 5 based on the position of the wall of the kitchen installation location detected in the wall detection process. In the present embodiment, four examples (1) to (4) will be described.
(1) When a wall is located on the right side of the gas stove 1 The CPU 71 determines whether or not the right side wall flag is 1 (S31). When the right side wall flag is 1 (S31: YES), the CPU 71 determines whether or not the left side wall flag is 0 (S32). When the left wall flag is 0 (S32: YES), the kitchen wall is located on the right side of the gas stove 1, and the kitchen wall is not located on the left side. Therefore, the CPU 71 specifies the right stove 4 as a stove close to the wall, sets a weak heating power range for the right stove 4, and sets a strong heating power range for the left stove 5 (S33). Thereby, in the right stove 4, it becomes possible to set the burner thermal power at each thermal power setting position in the weak thermal power range of 1 to 5, and in the left stove 5, the burner thermal power is set at each thermal power setting position in the strong thermal power range of 2 to 6. It becomes possible.

(2) When a wall is located on the left side of the gas stove 1 When the right side wall flag is 0 (S31: NO), the CPU 71 determines whether or not the left side wall flag is 1 (S35). When the left side wall flag is 1 (S35: YES), the kitchen wall is located on the left side of the gas stove 1, and the kitchen wall is not located on the right side. Therefore, the CPU 71 specifies the left stove 5 as the stove close to the wall, sets a weak heating power range for the left stove 5, and sets a strong heating power range for the right stove 4 (S36). Thereby, in the right stove 4, it becomes possible to set the burner thermal power at each thermal power setting position in the range of 2 to 6 strong thermal power, and in the left stove 5, the burner thermal power is set at each thermal power setting position in the weak thermal power range of 1 to 5. It becomes possible. Thereby, in the scene of said (1) and (2), a low capacity | capacitance stove can be arrange | positioned on the wall side with one kind of gas stove 1 without dropping the maximum output of the gas stove 1.

(3) When a pair of walls are located on the left and right sides of the gas stove 1 When both the right side wall flag and the left side wall flag are 1 (S31: YES, S32: NO), the walls are located on the left and right sides of the gas stove 1, respectively. To do. That is, the gas stove 1 is installed in a state of being sandwiched between a pair of left and right walls. Therefore, the CPU 71 sets a weak heating power range for both the right stove 4 and the left stove 5 (S34). In this case, the ability of the maximum output of the gas stove 1 is reduced, but since both the right stove 4 and the left stove 5 are close to the wall, a low thermal power range is set for both the right stove 4 and the left stove 5. Therefore, safety can be improved.
(4) When the wall is not located on either of the left and right sides of the gas stove 1 When both the right side wall flag and the left side wall flag are 0 (S31: NO, S35: NO), there are walls on the left and right sides of the gas stove 1. For example, an island type kitchen corresponds to this. In this case, the CPU 71 sets default settings (S37). As a default setting, for example, a strong heating power range may be set for the right stove 4 and a weak heating power range may be set for the left stove 5. Thereby, gas stove 1 can respond flexibly also to the scene of (4).

  In addition, the information of the thermal power adjustment range set to the right stove 4 and the left stove 5 is stored in the nonvolatile memory 74 as the stove thermal power setting information. Since the CPU 71 has completed the setting of the respective heating power adjustment ranges of the right stove 4 and the left stove 5, the CPU 71 sets the limit flag to 0 (S38). Thus, CPU71 complete | finishes this process and complete | finishes the stove heating power setting process of FIG.

  The ignition control process will be described with reference to FIG. The installer tries to ignite the right stove 4 or the left stove 5 in order to confirm that the gas stove 1 operates normally. For example, when the installer presses the operation button 11 to ignite the right stove 4, the CPU 71 reads the ignition control program from the ROM 72 and executes this processing. The CPU 71 determines whether or not the limit flag stored in the nonvolatile memory 74 is 0 (S41). When the restriction flag = 1 (S41: NO), when the gas stove 1 is installed, the stove heating power setting process is not executed or is not normally executed, and the respective heating power adjustment of the right stove 4 and the left stove 5 is performed. It is likely that the range is not set. Therefore, the CPU 71 displays an error on the display unit of the operation panel 24 without igniting the corresponding right stove 4 (S46). The installer who sees the error display can notice that the stove heating power setting process is not executed or is not normally executed, so that the stove heating power setting process can be executed again.

  On the other hand, when the restriction flag = 0 (S41: YES), since the setting of the respective heating power adjustment ranges of the right stove 4 and the left stove 5 has already been completed, the CPU 71 is provided in the gas supply pipe of the right stove 4. By opening the valve of the valve mechanism part 36 of the safety valve (not shown) and the gas amount adjusting device 30 and supplying gas, the right stove 4 is operated by operating the igniter 60 of the right stove 4 corresponding to the pressed operation button 11. 4 is ignited (S42). CPU71 starts the combustion control of the right stove 4 (S43). The right stove 4 can adjust the burner heating power in five stages within the set heating power adjustment range by rotating the operation button 11. The installer confirms that a low thermal power range is set for the stove on the wall side and a strong thermal power range is set for the stove on the opposite side of the wall side.

  The CPU 71 determines whether or not the right stove 4 has been extinguished due to the operation button 11 being pressed again (S44). Until the operation button 11 is pressed again (S44: NO), the CPU 71 returns to S44 and continues the combustion control. When the operation button 11 is pressed again (S44: YES), the CPU 71 closes the safety valve (not shown) provided in the gas supply pipe of the right stove 4 and the valve mechanism section 36 of the gas amount adjusting device 30 to the right. Fire the stove 4. The CPU 71 ends this process.

  As described above, the gas stove 1 according to the first embodiment includes the right stove 4 and the left stove 5 on the top plate 3. The right stove 4 and the left stove 5 have the same specifications. The gas amount adjusting device 30 of the right stove 4 adjusts the heating power of the right stove 4 by adjusting the amount of gas supplied to the right stove 4. The gas amount adjusting device 30 of the left stove 5 adjusts the heating power of the left stove 5 by adjusting the amount of gas supplied to the left stove 5. In the gas stove 1, the total maximum output of gas by the right stove 4 and the left stove 5 is determined in advance. In the casing 2 of the gas stove 1, a right sensor 77A and a left sensor 77B are provided. The right sensor 77A detects an obstacle (wall) within a predetermined distance range on the right side of the gas stove 1. The left sensor 77B detects an obstacle (wall) within a predetermined distance range on the left side of the gas stove 1. Based on the signals from the right sensor 77A and the left sensor 77B, the CPU 71 of the gas stove 1 identifies the stove closest to the kitchen wall from the right stove 4 and the left stove 5.

  The CPU 71 of the gas stove 1 sets a weak heat power range for the stove closer to the wall side of the kitchen in the heat power adjustable range by the gas amount adjusting devices 30 of the right stove 4 and the left stove 5, respectively. Set a strong firepower range for the stove on the opposite side. Here, the sum of the maximum outputs of the strong heating power range and the weak heating power range is set to the total maximum output of gas by the right stove 4 and the left stove 5. Thereby, since the capability of the stove on the wall side can be set low without reducing the capability of the gas stove 1, it is possible to consider the wall side that is easily heated. Further, regardless of whether the wall comes to the left or right of the gas stove 1 depending on where the gas stove 1 is installed, either the right stove 4 or the left stove 5 depending on the detection result by the right sensor 77A and the left sensor 77B. On the other hand, since a weak heating power range can be set, the ability of the burner on the wall side can be lowered with one kind of gas stove 1. Thereby, since it is not necessary to increase the kind of gas stove 1, management of the gas stove 1 to ship becomes easy, and since it is not necessary to select an installation place, the gas stove 1 which is easy to use can be provided.

  Moreover, in the said embodiment, the range which can adjust the thermal power by the gas amount adjusting device 30 is divided into 6 steps of 1-6. Thereby, the range of 1-5 including the stage with the weaker thermal power can be easily set as the weak thermal power range, and the range of 2-6 including the stage with the stronger thermal power can be easily set as the strong thermal power range.

  Moreover, in the said embodiment, the operation button 11 which receives operation of the thermal power of the right stove 4, and the operation button 13 which receives operation of the thermal power of the left stove 5 are provided. The gas amount adjusting devices 30 of the right stove 4 and the left stove 5 each include a motor 37 that is driven in accordance with the operation of the operation buttons 11 and 13. The gas amount adjusting device 30 adjusts the gas supply amount to the corresponding right stove 4 or left stove 5 by driving the motor 37. Therefore, the gas amount adjusting device 30 can be linked with each operation of the operation buttons 11 and 13 with high accuracy.

  In the above description, the right stove 4 is an example of the “first burner” of the present invention, and the left stove 5 is an example of the “second burner” of the present invention. The right sensor 77A is an example of the “first sensor” in the present invention, and the left sensor 77B is an example of the “second sensor” in the present invention.

-Second embodiment-
The second embodiment will be described with reference to FIGS. As described above, the gas stove 1 according to the first embodiment uses the right sensor 77A and the left sensor 77B to detect the wall at the location where the gas stove 1 is installed. Set a strong firepower range for the other stove. On the other hand, the gas stove 100 of the second embodiment defaults to a state in which a strong heating power range is set for the right stove 4 and a weak heating power range is set for the left stove 5, and the strong heating power range and the weak heating power range are manually set. It differs from 1st embodiment by the point provided with the left side strong thermal power switch 95 which can be switched by.

  As shown in FIG. 9, the gas stove 100 includes a switch input circuit 90, a sensor 91, a left-side high thermal power switch 95, and a confirmation button instead of the right sensor 77 </ b> A, the left sensor 77 </ b> B, and the sensor input circuit 87 of the first embodiment. 96. In addition, since the left strong thermal power switch 95 and the confirmation button 96 are mainly used by the installer, it is preferable to provide the left strong thermal power switch 95 and the confirmation button 96 in a place where the user cannot visually recognize the gas stove 1 in the installed state. The switch input circuit 90 inputs an ON signal of the left strong thermal power switch 95 to the control circuit 70. The sensor 91 detects the pressing of the confirmation button 96 and inputs a detection signal to the control circuit 70. For example, a dip switch or the like can be applied to the left strong heat power switch 95.

  The stove heating power setting process will be described with reference to FIG. When the installer installs the gas stove 1 on the counter top of the kitchen and presses the power button 25, the CPU 71 reads the stove heating power setting program from the ROM 72 and executes this processing. Note that the initial setting stove heating power setting information is stored in the nonvolatile memory 74 in advance. The stove heating power setting information in the initial state is information indicating a strong heating power range for the right stove 4 and a weak heating power range for the left stove 5. Further, the same restriction flag as in the first embodiment is stored in the nonvolatile memory 74, and 1 is set as an initial state.

  When installing the gas stove 1 on the counter top, the installer confirms whether the wall of the kitchen is located on the right side or the left side of the gas stove 1. When the wall is located within a predetermined distance on the left side of the gas stove 1, the installation contractor should set the left high heat power switch 95 to the low heating power range for the left stove 5 and the strong heating power range for the right stove 4. Do not turn on. On the other hand, when the wall is located within a predetermined distance on the right side of the gas stove 1, it is only necessary to set the low heating power range for the right stove 4 and the strong heating power range for the left stove 5. 95 may be turned on.

  The CPU 71 determines whether or not the left strong thermal power switch 95 is on (S52). When the left strong thermal power switch 95 is off (S52: NO), the stove thermal power setting information may remain in the initial state, so the CPU 71 determines whether or not the confirmation button 96 has been pressed (S54). On the other hand, when the left strong heat power switch 95 is turned on (S52: YES), the CPU 71 sets a low heat power range for the right stove 4 and a high heat power range for the left stove 5 (S53), and the non-volatile memory. The stove heating power setting information stored in 74 is rewritten.

  When the installer completes the setting of the respective heating power adjustment ranges of the right stove 4 and the left stove 5, the CPU 71 presses the confirmation button 96 in order to confirm the set heating power adjustment range. Until the confirmation button 96 is pressed (S54: NO), the CPU 71 returns to S52 and waits. If the confirmation button 96 is not pressed, the restriction flag remains at 1. Therefore, in the ignition control process shown in FIG. 8, even if the operation button 11 is pressed and ignition of the right stove 4 is attempted, Not ignited. When the confirmation button 96 is pressed (S54: YES), the CPU 71 sets a restriction flag stored in the nonvolatile memory 74 to 0 (S55). Accordingly, in the ignition control process shown in FIG. 8, if the operation button 11 is pressed and ignition of the right stove 4 is attempted, the right stove 4 is normally ignited. Therefore, since the right stove 4 and the left stove 5 can be used in a thermal power adjustment range suitable for the place where the gas stove 1 is installed, the highly safe gas stove 1 can be provided, and the same effect as in the first embodiment can be obtained. . The CPU 71 ends this process. In addition, CPU71 of the gas stove 100 of 2nd embodiment performs the ignition control process shown in FIG. 8 similarly to 1st embodiment.

  As described above, the gas stove 100 according to the second embodiment defaults to a state in which a high thermal power range is set for the right stove 4 and a weak thermal power range is set for the left stove 5, and the high thermal power range and the low thermal power range are set. A left-side strong heat switch 95 that can be manually switched is provided. Thereby, the gas stove 100 can also set the thermal power adjustment range of the burner close | similar to a wall side to a weak thermal power range according to the installation place to install similarly to 1st embodiment. In addition, the gas stove 100 includes a confirmation button 96 for confirming the setting when the setting of the respective heating power adjustment ranges of the right stove 4 and the left stove 5 is completed. Thereby, when the installation contractor installs the gas stove 100, if the gas stove 100 forgets the setting of the heating power adjustment range, the gas stove 100 restricts the ignition to the right stove 4 and the left stove 5, respectively. Gas stove 100 having a high height can be provided. Further, by making such a restriction, the installer can know that the setting of the heating power adjustment range has not been completed when the ignition of the right stove 4 and the left cooking stove 5 is confirmed. Can be completed.

  The present invention is not limited to the first and second embodiments, and various modifications can be made. Although the gas stove 1 and 100 of the said embodiment is a built-in stove, a table stove may be sufficient. The grill may be omitted. Although the top stove 3 is provided with the right stove 4 and the left stove 5, the back stove may be provided between them.

  The right sensor 77A and the left sensor 77B of the first embodiment are optical sensors, but may be other sensors. For example, the wall of the stove installation location may be detected using a contact-type sensor.

  The gas stove 1 according to the first embodiment includes the right sensor 77A and the left sensor 77B on the left and right sides of the housing 2, but either one may be omitted. For example, a state in which only the right sensor 77A is attached to the right side of the housing 2 and a high heat power range is set for the right stove 4 and a low heat power range is set for the left stove 5 may be set as a default. If the right sensor 77A does not detect a wall within a predetermined distance on the right side of the housing 2, the heating power adjustment range may be left as the default. When the right sensor 77 </ b> A detects a wall within a predetermined distance on the right side of the housing 2, the CPU 71 may set a weak heating power range for the right stove 4 and a strong heating power range for the left stove 5.

  In the ignition control process shown in FIG. 8, if the operation button 11 is pressed and the limit flag is 1 (S41: NO), the ignition of the right stove 4 is limited. For example, the burner thermal power is limited to low thermal power. It may be. Alternatively, the heating power adjustment ranges of the right stove 4 and the left stove 5 may be forcibly set to a weak heating power range to limit the burner heating power.

  In the gas stove 100 according to the second embodiment, a state in which a strong heating power range is set for the right stove 4 and a weak heating power range is set for the left stove 5 is set as a default, and the heating power adjustment range can be switched by the left strong heating power switch 95. However, for example, a state in which a weak heating power range is set for the right stove 4 and a strong heating power range is set for the left stove 5 may be set as a default, and the heating power adjustment range may be switched by the right strong heating power switch.

  In the above description, the left strong thermal power switch 95 is an example of the “switch” of the present invention. The CPU 71 that executes the stove heating power setting process shown in FIG. 10 is an example of the “setting unit” in the present invention. The CPU 71 that executes the process of S52 of FIG. 10 is an example of the “specifying unit” in the present invention.
