Description

[Technical field]

[0001] The present invention relates to a heating appliance with a seismic shutdown function that limits some of its functions when an earthquake occurs. [Background technology]

[0002] Conventionally, heating appliances are known that can close the gas valve, stop combustion, and switch to safety control when an acceleration sensor detects earthquake tremors above a predetermined value, or when an emergency earthquake alert is received via communication.

[0003] For example, the heating device operation system of Patent Document 1 is composed of a gas fan heater connected and set to enable wireless communication, and a smartphone. When the smartphone receives an emergency earthquake alert transmitted from a specific communication center such as a base station of a telecommunications carrier while the smartphone and the gas fan heater are connected for communication, the smartphone displays the word "Received" in the emergency information reception display area on the screen, and displays the word "Emergency stop" in the status display area.

[0004] In addition, when an emergency earthquake warning is distributed from a specific communication center to an area at risk of damage from an earthquake, the smartphone receives the emergency earthquake warning, and based on the reception, the smartphone transmits an emergency stop signal to the gas fan heater wirelessly connected via Bluetooth (registered trademark). Furthermore, when the gas fan heater receives the emergency stop signal, the gas fan heater executes emergency stop control based on the reception, and emergency stops the operation of the gas fan heater (Patent Document 1 / paragraphs 0062 and 0064, FIG. 11). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2017-163384 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the above heating device operation system requires that the heating equipment (gas fan heater) and the communication terminal (smartphone) are in communication with each other, and that the communication terminal and the communication center are in communication with each other. Therefore, if communication is cut off, the system does not function, and users must constantly pay attention to the communication status.

[0007] Furthermore, if the shaking was sudden, heating equipment could tip over before normal operation had stopped, which could lead to a fire.

[0008] The present invention has been made in consideration of the above background, and aims to provide a heating appliance that can execute operational control quickly in response to the occurrence of an earthquake or the like, regardless of the communication state. [Means for solving the problem]

[0009] In order to achieve the above object, the present invention provides a heating device including a heating unit that heats an object to be heated, and a control unit that has a heating operation instruction unit that recognizes a heating operation instruction related to the heating operation of the heating unit and controls the heating operation of the heating unit based on the heating operation instruction, The heating operation control unit further includes a voice input unit for inputting the heating operation instruction by voice, and the control unit, during the heating operation of the heating unit, The external device receives voice information in response to a disaster warning from the communication center. The heating operation instruction Before When a voice is input to the voice input unit, a heating operation limiting control is executed to stop or limit the heating operation of the heating unit.

[0010] The heating appliance of the present invention is equipped with a voice input unit for inputting voice heating operation instructions, and the control unit (heating operation instruction unit) of the heating appliance can recognize a disaster alert issued from an external device such as a television or smartphone as a heating operation instruction.

[0011] When the control unit recognizes a disaster alarm during heating operation of the heating unit, it executes heating operation restriction control. This heating device can be a highly safe device, for example, by restricting the heating power before actual earthquake shaking occurs, but the heating device and external devices do not need to be in a state of communication. This has the advantage that users of the heating device are freed from the hassle of communication connections.

[0012] In the heating device of the present invention, When the heating operation restriction control is executed, it is preferable that the control unit continues the heating operation restriction control until a predetermined instruction is input via the heating operation instruction unit.

[0013] According to this configuration, the heating device continues the heating operation restriction control until the user confirms that the situation is safe and issues a predetermined instruction by operating a switch, inputting a voice, etc. This improves the safety of the device.

[0014] In addition, in the heating device of the present invention, When the heating operation restriction control is executed, it is preferable that the control unit continues the heating operation restriction control until a first predetermined time has elapsed from the start of the execution of the heating operation restriction control.

[0015] According to this configuration, the heating operation limit control is continued until the earthquake tremors subside, that is, until the first predetermined time has elapsed since the heating operation limit control was executed. This allows the heating device to release the heating operation limit control at an appropriate time while increasing the safety of the device.

[0016] In addition, in the heating device of the present invention, Further comprising a vibration detection unit that detects vibration of the heating device, When the heating operation restriction control is executed, it is preferable that the control unit continues the heating operation restriction control until a second predetermined time has elapsed from the start of execution without the vibration detection unit detecting vibrations equal to or greater than a predetermined value.

[0017] The heating device of the present invention is equipped with a vibration detection unit, and is therefore capable of detecting vibrations such as earthquakes. When a disaster alarm is input, the heating device transitions to heating operation limit control, but in reality, there may be little or no vibration. Therefore, without detecting vibrations of a predetermined value or more, the heating operation limit control continues until the second predetermined time has elapsed from the start of execution of the heating operation limit control. This also allows the present heating device to release the heating operation limit control at an appropriate time while increasing the safety of the device.

[0018] In addition, in the heating device of the present invention, Further comprising a notification unit that notifies a cancellation instruction method of the heating operation limit control, It is preferable that the notification unit notifies the cancellation instruction method immediately after the heating-operation restriction control is executed or when a third predetermined time has elapsed since the start of the execution of the heating-operation restriction control.

[0019] The heating appliance of the present invention is provided with a notification unit such as a liquid crystal display unit, and the notification unit notifies a method for instructing cancellation of the heating operation limit control immediately after the heating operation limit control is executed or when a third predetermined time has elapsed since the start of the execution. Since the user can recognize the cancellation of the heating operation limit control without referring to an instruction manual or the like, the device can be made highly convenient.

[0020] In addition, in the heating device of the present invention, It is preferable that the control unit executes a heat reduction of the heating unit as the heating operation restriction control, and does not accept input of the heating operation instruction except for turning off the heating unit during a period during which the heat reduction continues.

[0021] When the heating power of the heating unit is reduced as a heating operation restriction control, the control unit refuses to input a heating operation command other than extinguishing, so that the heating power cannot be increased inadvertently until safety is confirmed. This allows the heating device to ensure the safety of the device.

[0022] In addition, in the heating device of the present invention, When the control unit executes a heating power reduction of the heating unit as the heating operation restriction control, it is preferable that the control unit restores the heating power state before the heating operation restriction control is executed when the heating operation restriction control is released.

[0023] When the heating power of the heating unit is reduced as the heating operation limit control, the control unit controls the heating power to be restored to the original state when safety is confirmed and the heating operation limit control is released. This makes it easier for the user to continue cooking after the heating operation limit control is released, thereby improving the convenience of the heating appliance as a device.

[Figure 6] 13 is a flowchart of heating operation limit control of a heating cooker (minimum heat power, modified form). DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] Hereinafter, the heating device of the present invention will be described with reference to the drawings.

[0026] First, a cooking system according to an embodiment of a heating appliance will be described with reference to Figures 1 and 2. The cooking system 1 is composed of a cooking appliance 10 and an external appliance 30 such as a smartphone. The external appliance 30 has a function of receiving a disaster warning (mainly an emergency earthquake warning) from a communication center 50 and automatically transmitting the warning.

[0027] In this embodiment, the cooking device 10 is a gas stove. As shown in Fig. 1, the cooking device 10 is provided with a left burner 5a, a right burner 5b, and a rear burner 5c, which are disposed at the left front part, the right front part, and the rear center part of the top plate part 4, respectively, as combustion-type heating parts for heating objects to be heated. The cooking device 10 also includes a grill 20 disposed in the housing of the cooking device 10 so as to be openable and closable at the front.

[0028] Each of the burners 5a, 5b, and 5c has a burner with a different heating capacity (maximum heat). For example, the heating capacity of each of the burners 5a, 5b, and 5c is large, medium, and small in the order of the left burner 5a, the right burner 5b, and the rear burner 5c (or in the order of the right burner 5b, the left burner 5a, and the rear burner 5c). The heating capacity of each of the burners 5a, 5b, and 5c may be the same for the left burner 5a and the right burner 5b, and smaller for the rear burner 5c, that is, large, large, and small in the order of the right burner 5b, the left burner 5a, and the rear burner 5c.

[0029] On the front surface of the cooking device 10, there are provided operation buttons 11a, 11b, and 11c for igniting, extinguishing, and adjusting the heat of the burners 5a, 5b, and 5c, respectively, and an operation button 21 for igniting, extinguishing, and adjusting the heat of the grill 20. In this case, for example, pressing each of the operation buttons 11a, 11b, and 11c ignites or extinguishes the corresponding burner 5a, 5b, or 5c, respectively, and rotating each of the operation buttons 11a, 11b, and 11c adjusts the heat of the corresponding burner 5a, 5b, or 5c, respectively.

[0030] The same applies to the operation button 21 for the grill 20. Note that the operation units for turning on and off the flames of the burners 5a, 5b, and 5c and the grill 20 may be separate from the operation unit for adjusting the flame power.

[0031] In addition, a push-open type burner operation unit 12 and a grill operation unit 22 are provided on the front surface of the cooking device 10. In this case, when the burner operation unit 12 is pressed, the burner operation unit 12 opens, and a touch panel type burner operation panel 13 is exposed and operable. The burner operation panel 13 is capable of switching the operation of each of the burners 5a, 5b, and 5c. A liquid crystal display unit 14 is provided adjacent to the burner operation panel 13. The burner operation panel 13 does not have to be a touch panel type, and may be a tact switch provided for operating each of the burners 5a, 5b, and 5c. Each of the burners 5a, 5b, and 5c can be operated by pressing the tact switch.

[0032] When grill operation unit 22 is pressed, it opens, exposing touch panel type grill operation panel 23 for operation. Grill operation panel 23 may be a tact switch, and grill 20 can be operated by pressing the tact switch. Each of stove operation panel 13 and grill operation panel 23 may be provided on the outer surface of cooking appliance 10 in an exposed state.

[0033] The stove operation panel 13 is configured so that the user can perform operations related to the operation control of each stove 5a, 5b, 5c (for example, turning on and off the water boiling operation or rice cooking operation, setting the automatic cooking operation, setting the timer time, setting the heating temperature, etc.), and is also configured so that various information related to the operation of each stove 5a, 5b, 5c can be displayed. The same applies to the grill operation panel 23.

[0034] In addition to the above configuration, as shown in FIG. 2, the cooking device 10 is equipped with a control unit 7 having the function of controlling the overall operation of the cooking device 10, an audio input unit 16 such as a microphone that can input audio information from an external device 30, and a seismic sensor 17 consisting of an acceleration sensor or the like.

[0035] The control unit 7 is configured with one or more electronic circuit units including, for example, a microcomputer, a memory, an interface circuit, etc. Sensing signals from a plurality of sensors (including the seismic sensor 17) provided in the cooking appliance 10 and operation signals from the operation buttons 11a, 11b, 11c, 21 and the operation panels 13, 23 are input to this control unit 7.

[0036] The control unit 7 is composed of a heat power control unit 7A, a display control unit 7B, and a vibration determination unit 7C. The heat power control unit 7A (the "heating operation instruction unit" of the present invention) has a function realized by both or either of the implemented hardware configuration and program (software configuration) to control the operation of each of the burners 5a, 5b, 5c and the grill 20, that is, the heating units 5, 20 (more specifically, operation control related to ignition, extinguishing, and heat power adjustment).

[0037] More specifically, the operation of each of the burners 5a, 5b, 5c and the grill 20 is controlled through the operation of an on-off valve and a flame adjustment valve provided in a fuel supply passage (not shown) corresponding to each of the left burner 5a, the right burner 5b, the rear burner 5c and the grill 20, as well as through the operation of an igniter (not shown).

[0038] Furthermore, when the thermal power control unit 7A recognizes a disaster warning (mainly an emergency earthquake alert) regarding a disaster that is sent from the external device 30 and input via the voice input unit 16, it executes heating operation restriction control to stop or restrict the heating operation of each of the burners 5a, 5b, 5c and the grill 20. Since the voice input unit 16 can always pick up voice while the cooking appliance 10 is in use, the cooking appliance 10 can execute control corresponding to an earthquake or the like, regardless of the communication state with the external device 30. Therefore, the user can cook using the cooking appliance 10 without worrying about communication connections.

[0039] Immediately after the heating operation restriction control is executed or when a predetermined time (e.g., 3 minutes) has elapsed since the start of the execution, the display control unit 7B causes the liquid crystal display unit 14 (the "notification unit" of the present invention) to display a method for issuing an instruction to release the heating operation restriction control. Specifically, a message such as "Press and hold any key on the stove operation panel to release the control" is displayed on the liquid crystal display unit 14, and the heating operation restriction control continues until the user performs the operation.

[0040] Although details will be described later, when the heating operation limiting control is executed, the stove in use is turned off or the heat is reduced. Therefore, the display control unit 7B may display the fact so that the user is aware of it. If the cooking device 10 has an audio output unit, the notification may be given by audio.

[0041] When the heating operation limit control is executed, the control unit 7 can continue the heating operation limit control until a predetermined time (e.g., 7 minutes) has elapsed since the start of the heating operation limit control. For example, when the heating power of the left burner 5a is reduced as the heating operation limit control, it is desirable to return the heating power to the state before the heating operation limit control is executed when the predetermined time has elapsed.

[0042] The vibration determination unit 7C determines the shaking of an earthquake based on the detection signal from the seismometer 17 (the "vibration detection unit" of the present invention). If the vibration determination unit 7C determines that it is dangerous to continue cooking, it instructs the heat control unit 7A to stop the heating operation of the burners 5a, 5b, 5c and the grill 20. The vibration determination unit 7C may also instruct the display control unit 7B to display the action that the user should take.

[0043] When a disaster alarm is input, the cooking appliance 10 executes the heating operation limit control, but in reality, there may be almost no shaking. Therefore, the heating operation limit control continues until a predetermined time (e.g., 5 minutes) has elapsed since the start of execution of the heating operation limit control without the vibration of a predetermined value or more being detected by the seismometer 17 and the control unit 7 (vibration determination unit 7C).

[0044] When the predetermined time has elapsed, the heating power control unit 7A of the control unit 7 releases the heating operation limit control. Specifically, the heating power of the stove (or grill) that executed the heating operation limit control is returned to its original state. This allows the cooking appliance 10 to release the heating operation limit control at an appropriate timing while increasing the safety of the device.

[0045] 2, the external device 30 is composed of a control unit 31 that controls the operation of the external device 30, a communication unit 32 for wireless communication, and an audio output unit 33 such as a speaker. The external device 30 is, for example, a portable communication terminal such as a smartphone, a tablet terminal, or a mobile computer used by a user of the cooking appliance 10.

[0046] The control unit 31 of the external device 30 is configured by an electronic circuit unit including, for example, a microcomputer, a memory, an interface circuit, etc., and receives an operation signal from the operation unit. The control unit 31 executes a pre-installed application, thereby enabling communication with a server in the communication center 50 via an external network NW including the Internet, a public line network, etc., and a communication unit 32 (see FIG. 1).

[0047] Furthermore, when a disaster warning is transmitted from the communication center 50, the control unit 31 controls the audio output unit 33 to output a warning sound or a message such as "It's an earthquake" or "Large shaking will occur" as audio information. The external device 30 may be a television, radio, cable broadcasting, etc. that outputs a disaster warning.

[0048] Next, a flow chart of the heating operation limiting control of the cooking appliance 10 will be described with reference to Figs.

[0049] First, FIG. 3 shows a flow chart for the heating operation limit control in which the flame of a burner (for example, for the left burner 5a) is extinguished.

[0050] In the cooking appliance 10, it is confirmed whether or not the burner is ignited (STEP 01). If the burner is currently ignited, the process proceeds to STEP 02, and if the burner is not currently ignited, the process loops until the burner is ignited.

[0051] If the burner is being ignited ("YES" in STEP 01), it is determined whether or not the cooking appliance 10 (control unit 7, audio input unit 16) has detected an emergency earthquake warning (STEP 02). The audio input unit 16 is always capable of picking up audio while the cooking appliance 10 is in use, and is therefore not affected by the state of communication with the external device 30. If the cooking appliance 10 has detected an emergency earthquake warning, the process proceeds to STEP 03, and if it has not detected an emergency earthquake warning, the process loops until it does (it may end once).

[0052] When the cooking appliance 10 detects an emergency earthquake warning ("YES" in STEP 02), it starts heating operation restriction control (extinguishing) (STEP 03). Normally, an emergency earthquake warning is transmitted from an external device 30 (smartphone, radio, etc.) before actual shaking occurs. Therefore, the heating operation restriction control here is a process in which the cooking appliance 10 extinguishes the burner flame in preparation for danger after recognizing the emergency earthquake warning and before the occurrence of earthquake shaking.

[0053] Next, the cooking appliance 10 displays a cancellation instruction method (STEP 04). Specifically, a cancellation method for the heating operation restriction control (operation instructions from the operation panel 13, voice input instructions (including special phrases) from the voice input unit 16, etc.) is displayed on the liquid crystal display unit 14. This allows the user to cancel the heating operation restriction control without referring to the instruction manual.

[0054] Next, the cooking device 10 judges whether or not a first predetermined time has elapsed (STEP 05). The first predetermined time is a time for automatically releasing the heating operation restriction control, and is, for example, 7 minutes. If the first predetermined time has elapsed, the process proceeds to STEP 08, and if the first predetermined time has not yet elapsed, the process proceeds to STEP 06.

[0055] First, the case where the first predetermined time has not elapsed ("NO" in STEP 05) will be described. In this case, the cooking device 10 judges whether or not a release instruction has been given (STEP 06). A release instruction refers to the predetermined operation or voice input shown in STEP 04. If a release instruction has been given, the process proceeds to STEP 07, and if no release instruction has been given, the process returns to STEP 05.

[0056] If a release command is received ("YES" in STEP 06), the cooking device 10 determines whether or not a predetermined time has elapsed (STEP 07). The predetermined time here is desirably shorter than the first predetermined time. The heating operation restriction control of the cooking device 10 continues until the predetermined time (e.g., 5 minutes) has elapsed. If the predetermined time has elapsed, the process proceeds to STEP 08, and if the predetermined time has not yet elapsed, the process loops until the predetermined time has elapsed.

[0057] When the first predetermined time has elapsed ("YES" in STEP 05) or when the predetermined time has elapsed ("YES" in STEP 07), the cooking appliance 10 releases the heating operation restriction control (STEP 08). That is, the heating operation restriction control is released when the first predetermined time has elapsed or when the release instruction and the predetermined time have elapsed.

[0058] Finally, the cooking appliance 10 re-ignites the burner (STEP 09). This returns the burner to the state it was in before the heating operation limit control was executed, allowing the user to continue cooking.

[0059] In the cooking appliance 10 of this embodiment, ignition and extinguishing are controlled by operating the stove operation panel 13, so that the appliance re-ignites automatically; however, in the case of a cooking appliance that is ignited by pressing a switch, the user must manually operate the appliance to re-ignite the appliance.

[0060] This completes the series of processes for the heating operation restriction control. In the above flow chart, the cancellation instruction method is notified immediately after the heating operation restriction control is executed, but the cancellation instruction method may be notified when a third predetermined time (e.g., 3 minutes or the timing when the control can be cancelled) has elapsed since the start of execution. If the cooking device 10 has an audio output unit, the cancellation method may be output by audio.

[0061] As the heating operation limiting control, the power supply to the cooking appliance 10 may be turned off (STEP 03'). In this case, when the heating operation limiting control is released, the power supply is automatically turned on (STEP 09'). Note that the control may be such that the burner is automatically reignited.

[0062] Fig. 4 shows a modified form of the flow chart in the case where the burner flame is extinguished as the heating operation limit control. Here, various controls are executed based on the vibrations detected by the seismometer 17. Note that the explanation of the same controls as in Fig. 3 will be omitted.

[0063] The determination of whether the burner is ignited in STEP 11, the determination of whether an emergency earthquake warning has been detected in STEP 12, the start of heating operation restriction control in STEP 13, and the display of the release instruction method in STEP 14 are the same as STEPs 01 to 04 in FIG.

[0064] After STEP 14, the cooking appliance 10 judges whether or not vibrations of a predetermined value or more have been detected (STEP 15). Vibrations of a predetermined value or more mean dangerous shaking (for example, seismic intensity 3 or more) when the burner is ignited. If vibrations of a predetermined value or more have been detected, the process proceeds to STEP 16, and if vibrations of a predetermined value or more have not been detected, the process proceeds to STEP 17.

[0065] If vibrations of a predetermined value or more are detected ("YES" in STEP 15), the cooking device 10 displays an error (STEP 16). Specifically, a message such as "Large vibrations have been detected, so the power will be turned off" is displayed on the liquid crystal display unit 14 of the cooking device 10, and all functions of the cooking device 10 are stopped at this time. After that, the series of processes for the heating operation restriction control are terminated.

[0066] On the other hand, if vibrations of a predetermined value or more are not detected ("NO" in STEP 15), the cooking appliance 10 judges whether or not the second predetermined time has elapsed (STEP 17). Although the heating operation limit control is executed in response to an emergency earthquake alert, there are cases where no large shaking actually occurs. The second predetermined time is a time for automatically releasing the heating operation limit control in such a situation, and is, for example, 5 minutes. If the second predetermined time has elapsed, the process proceeds to STEP 18, and if the second predetermined time has not yet elapsed, the process returns to STEP 15.

[0067] If the second predetermined time has elapsed ("YES" in STEP 17), the cooking appliance 10 releases the heating operation restriction control (STEP 18). That is, the heating operation restriction control is released when the second predetermined time has elapsed without detecting vibrations of a predetermined value or more.

[0068] Finally, the cooking appliance 10 re-ignites the burner (STEP 19). This returns the burner to the state it was in before the heating operation limit control was executed. After that, the series of processes for the heating operation limit control is terminated.

[0069] Although the heating operation limit control in Fig. 3 and the heating operation limit control (modified form) in Fig. 4 are separated for the sake of simplicity of explanation, both may be combined. In other words, in addition to the heating operation limit control in Fig. 3, various controls related to the seismic sensor 17 may be executed.

[0070] Next, FIG. 5 shows a flow chart of the heating operation limit control in which the heat of a burner (for example, for the left burner 5a) is minimized.

[0071] In the cooking appliance 10, it is confirmed whether or not the burner is ignited (STEP 21). If the burner is currently ignited, the process proceeds to STEP 22, and if the burner is not currently ignited, the process loops until the burner is ignited.

[0072] If the burner is being ignited ("YES" in STEP 21), it is determined whether or not the cooking appliance 10 (control unit 7, audio input unit 16) has detected an emergency earthquake warning (STEP 22). The audio input unit 16 is always capable of picking up audio while the cooking appliance 10 is in use, and is therefore not affected by the state of communication with the external device 30. If an emergency earthquake warning is detected, the process proceeds to STEP 23, and if an emergency earthquake warning is not detected, the process loops until it is detected (it may end once).

[0073] When the cooking appliance 10 detects an emergency earthquake warning ("YES" in STEP 22), it starts heating operation limit control (minimum heating power) (STEP 23). The heating operation limit control here is a process in which, after the cooking appliance 10 recognizes the emergency earthquake warning, the heating power of the burner is reduced to minimum in preparation for danger before the occurrence of earthquake tremors.

[0074] Next, the cooking appliance 10 displays a cancellation instruction method (STEP 24). Specifically, the liquid crystal display unit 14 of the cooking appliance 10 displays a cancellation method for the heating operation restriction control (operation instructions from the operation panel 13, voice input instructions from the voice input unit 16, etc.).

[0075] Next, the cooking appliance 10 judges whether or not the extinguishing operation has been performed manually (STEP 25). Since there may be situations in which it is better for the user to extinguish the fire at their own discretion, the extinguishing operation can be performed manually (or by voice input). Note that operations other than extinguishing the fire, such as returning the fire to its original power level (or by voice input), are not accepted. If the extinguishing operation has been performed, the process proceeds to STEP 26, and if the extinguishing operation has not been performed, the process proceeds to STEP 27.

[0076] If the user performs the extinguishing operation ("YES" in STEP 25), the cooking appliance 10 normally stops (STEP 26). After that, the series of processes for the heating operation restriction control ends.

[0077] On the other hand, if the user has not performed the extinguishing operation ("NO" in STEP 25), the cooking device 10 judges whether or not a first predetermined time has elapsed (STEP 27). The first predetermined time is the time for automatically releasing the heating operation restriction control. If the first predetermined time has elapsed, the process proceeds to STEP 30, and if the first predetermined time has not yet elapsed, the process proceeds to STEP 28.

[0078] If the first predetermined time has not elapsed ("NO" in STEP 27), the cooking device 10 determines whether or not a release command has been issued (STEP 28). If a release command has been issued, the process proceeds to STEP 29, and if no release command has been issued, the process returns to STEP 27.

[0079] If a release command is received ("YES" in STEP 28), the cooking device 10 determines whether or not a predetermined time has elapsed (STEP 29). If the predetermined time has elapsed, the process proceeds to STEP 30, and if the predetermined time has not yet elapsed, the process loops until the predetermined time has elapsed.

[0080] When the first predetermined time has elapsed ("YES" in STEP 27) or when the predetermined time has elapsed ("YES" in STEP 29), the cooking appliance 10 releases the heating operation restriction control (STEP 30).

[0081] Finally, the cooking appliance 10 returns the burner to its original heating power state (STEP 31). This returns the burner heating power to the state before the heating operation limit control was executed, allowing the user to continue cooking. The burner heating power may be returned to the heating power before a predetermined time, not limited to the state immediately before the heating operation limit control was executed. This completes the series of processes for the heating operation limit control.

[0082] As the heating operation restriction control, the heating power of the cooking appliance 10 may be reduced from the current level (STEP 23'). In this case, during the heating operation restriction control period, only the extinguishing operation and an operation (or voice input) to further reduce the heating power are accepted.

[0083] Finally, Fig. 6 shows a modified form of the flow chart in which the burner flame is set to the minimum heat as the heating operation limit control. Here, various controls are executed based on the vibrations detected by the seismometer 17. Note that the explanation of the same controls as in Fig. 5 will be omitted.

[0084] The determination of whether the burner is ignited in STEP 41, the determination of whether an emergency earthquake warning has been detected in STEP 42, the start of heating operation limit control (minimum heat) in STEP 43, the display of the release instruction method in STEP 44, the determination of whether the fire extinguishing operation has been performed in STEP 45, and the normal shutdown in STEP 46 are the same as STEPs 21 to 26 in Figure 5.

[0085] If the extinguishing operation has not been performed manually ("NO" in STEP 45), the cooking device 10 judges whether or not vibrations of a predetermined value or more have been detected (STEP 47). If vibrations of a predetermined value or more have been detected, the process proceeds to STEP 48, and if vibrations of a predetermined value or more have not been detected, the process proceeds to STEP 49.

[0086] If vibrations of a predetermined value or more are detected ("YES" in STEP 47), the cooking device 10 displays an error (STEP 48). Specifically, a message such as "Large vibrations have been detected, so the power will be turned off" is displayed on the liquid crystal display unit 14 of the cooking device 10, and all functions of the cooking device 10 are stopped. After that, the series of processes for the heating operation restriction control are terminated.

[0087] On the other hand, if vibrations of a predetermined value or more have not been detected ("NO" in STEP 47), the cooking device 10 judges whether or not the second predetermined time has elapsed (STEP 49). If the second predetermined time has elapsed, the process proceeds to STEP 50, and if the second predetermined time has not yet elapsed, the process returns to STEP 47.

[0088] If the second predetermined time has elapsed ("YES" in STEP 49), the cooking appliance 10 releases the heating operation restriction control (STEP 50). That is, the heating operation restriction control is released when the second predetermined time has elapsed without detecting vibrations of a predetermined value or more.

[0089] Finally, the cooking appliance 10 returns the burner to the original heating power state (STEP 51). This returns the burner to the state before the heating operation limit control was executed, allowing the user to continue cooking. This completes the series of processes for the heating operation limit control.

[0090] The heating operation limit control in Fig. 5 and the heating operation limit control (modified form) in Fig. 6 are also separated for the sake of simplicity of explanation, but both may be combined. That is, in addition to the heating operation limit control in Fig. 5, various controls related to the seismic sensor 17 may be executed. Furthermore, the above-mentioned fire extinguishing (see Figs. 3 and 4) may also be executed as the heating operation limit control, and the device or system may be configured to execute various controls in the case of fire extinguishing and the case of minimum fire power.

[0091] As described above, the present invention is not limited to the above-described embodiment and modifications, and can be embodied in various forms without departing from the spirit and scope of the present invention.

[0092] In the above embodiment, the heating appliance is a cooking device, but it may be a space heater or a gas combustion device. Also, the burners of the stoves 5a to 5c are shown as examples of the heating unit, but it may be a grill 20, an IH heater, or other heating means, and the operation panels 13 and 23 may include some operation buttons and dials.
