Description

The present invention relates to a cooking apparatus in which a cooking utensil that suppresses the thermal power of the burner is executed when the cooking utensil is not placed on the burner, a cooking utensil used therefor, and a cooking system including these.

Conventionally, it has a cooking utensil detecting means for detecting whether or not a cooking utensil such as a pot or a frying pan is placed on the burner, and when it is detected that the cooking utensil is not placed on the burner, the burner is used. There is known a cooking device that performs thermal power suppression control such as extinguishing a fire or weakening the thermal power of a burner. In addition, even if the cooking utensil is not detected on the burner by shaking the pot to operate the cooking utensil during cooking, in order to maintain the thermal power of the burner, a release switch that releases the thermal power suppression control on the front part of the stove body. (For example, Patent Document 1) has also been proposed.

However, it is complicated for the user to operate the release switch before the start of cooking or during cooking, and the workability of cooking is inferior. Therefore, it is desired to automatically cancel the thermal power suppression control according to cooking.

On the other hand, in order to improve safety against earthquakes, a cooking device having an acceleration detecting means for detecting an acceleration applied to the device and outputting an acceleration signal and a frequency detecting means for detecting the frequency of the acceleration signal has been proposed. (Patent Document 2). In this cooking device, the seismic vibration that requires extinguishing the burner has a lower frequency and a larger amplitude than the artificial vibration, and the amplitude of the acceleration signal detected by the acceleration detecting means and the frequency by the frequency detecting means are used. When the characteristic point determined by the relationship is in the predetermined cutoff region, it is determined to be seismic vibration, and when the characteristic point is outside the predetermined cutoff region, it is determined to be artificial vibration such as swinging a pot or opening / closing the grill door. It is configured to ensure that the burner is extinguished in the event of seismic vibration. Therefore, even in a cooking apparatus in which the thermal power suppression control is executed, it is conceivable to prevent the thermal power suppression control from being executed when artificial vibration is detected by using such acceleration information.

However, the artificial vibration applied to the cooking device during cooking includes not only the vibration caused by the cooking utensil colliding with the cooking device by shaking the pot, but also the vibration on the burner during or at the end of cooking. It also includes the vibration caused by the action of raising the pot to lift the cooking utensil from the top and the action of lowering the pot to move the cooking utensil from the burner to the top plate or the counter top. In particular, when a cooking utensil detecting means having a spring member is used, when the cooking utensil is lifted from the burner, vibration is applied to the cooking apparatus by the elastic force of the spring member. In such a case, since the cooking utensil is not placed on the burner, it is necessary to suppress the heating power. Therefore, if it is determined whether or not to uniformly execute the thermal power suppression control based only on the discrimination between the seismic vibration and the artificial vibration as in Patent Document 2, the thermal power suppression is performed even when the thermal power suppression control is required. There is a problem that there is no.

On the other hand, in order to prevent the cooked food from being burnt, the cook may perform a so-called tilting operation in which the cooking utensil is shaken while floating from the burner. In such a case, since the cooking utensil does not collide with the cooking utensil, the state of the cooking utensil is obtained by the acceleration detecting means provided in the cooking utensil even though the cooking in which the maintenance of the thermal power of the large fire is desired is continued. Cannot be detected. Therefore, when the cooking apparatus is provided with the acceleration detecting means as in Patent Document 2, there is a problem that the heating power suppression control is activated while the cooking utensil is away from the burner, and the heating power is suppressed. Further, in stir-fry cooking or the like, there is a case where the cooking utensil is moved back and forth or left and right while the cooking utensil is detected on the burner, and then the pan shaking operation is performed. In such a case, after the operation of shaking the pot, the heating power suppression control is once executed until the cooking utensil is lifted on the burner and artificial vibration is applied to the cooking device by the operation of shaking the pot, and the heating power is increased. There is a problem that it is suppressed. In particular, in a cooking device in which a heating power suppression control for extinguishing a burner is executed, it is necessary to perform a reignition operation, which significantly reduces the workability of cooking.

The present invention solves the above problems, and an object of the present invention is to provide a cooking apparatus, a cooking utensil, and a cooking system having excellent cooking workability and high safety.

According to one aspect of the invention
With a burner
A cooking utensil detection means that detects the presence or absence of a cooking utensil on the burner,
When the cookware detection means detects that the cookware is not placed on the burner, the device-side control means that performs the heat suppression control for extinguishing the burner or reducing the heat of the burner, and
It is equipped with a device-side wireless communication means that receives acceleration information applied to the cooking utensil from the cooking utensil.
When the burner is ignited while the cookware detection means has detected the placement of the cookware , the device-side control means initializes the position information of the cookware and at least the acceleration information received by the device-side wireless communication means. When an artificial vibration of a predetermined frequency or higher is included in the uniaxial direction, a cooking device having a configuration for disabling the thermal power suppression control is provided.

When the user operates the cooking utensil, artificial vibration is applied to the cooking utensil, but the operation of shaking the pot to move the cooking utensil back and forth or left and right on the burner, and the cooking utensil on the burner back and forth and In the movement of shaking the pot in the vertical direction (hereinafter, when these movements are collectively referred to as "movement of shaking the pot, etc."), the cooking utensil is repeatedly moved in the positive and negative directions in at least one axial direction, so that the cooking utensil is used. Vibration is applied periodically. On the other hand, the operation of raising the pot to lift the cooking utensil from the top of the burner during or at the end of cooking, and the operation of lowering the pot to move the cooking utensil from the top of the burner to the top plate or the counter top (hereinafter, these). When the movements are collectively expressed (referred to as "movements such as raising a pot"), the cooking utensils are moved in either the positive direction or the negative direction in at least one axial direction, so that the cooking utensils are vibrated with little periodicity. Be applied. The vibration caused by any of the movements is an artificial vibration, but the frequency when the acceleration information applied to the cooking utensil by the movement such as shaking the pot is frequency-analyzed is higher than that applied to the cooking utensil by the movement such as raising the pot. Is also expensive.

Therefore, when the acceleration information applied to the cooking utensil contains artificial vibration of a predetermined frequency or higher in at least one axial direction, if the thermal power suppression control is disabled, the manual thermal power suppression control is canceled. It is possible to smoothly continue cooking that requires a large amount of heat, such as cooking stir-fried foods. On the other hand, when the acceleration information applied to the cooking utensil does not include artificial vibration above a predetermined frequency in any of the axial directions, the thermal power suppression control is executed. When the cookware is moved, the burner can be surely extinguished or the firepower of the burner can be reduced. This makes it possible to achieve both workability and safety of cooking.

Further, in general, at the start of cooking, the user places a cooking utensil on the burner and then ignites the burner, and after the cooking has progressed to some extent, the user performs an operation such as shaking a pot. Therefore, if the position information of the cooking utensil is initialized based on the position when the burner is ignited while the placement of the cooking utensil is detected by the cooking utensil detecting means, the acceleration information applied to the cooking utensil can be obtained. It can be judged accurately.

According to another aspect of the invention

When the cookware detection means detects that the cookware is not placed on the burner, the device-side control means that performs the heat suppression control for extinguishing the burner or reducing the heat of the burner, and
It is equipped with a device-side wireless communication means that receives acceleration information applied to the cooking utensil from the cooking utensil.
The device-side wireless communication means receives contact information from the cooking utensil when the user touches the cooking utensil, and receives the contact information from the cooking utensil.
When the device-side control means receives the contact information by the device-side wireless communication means while the cookware detection means detects the placement of the cookware, the device-side control means initializes the position information of the cookware and receives it by the device-side wireless communication means. When the acceleration information to be performed contains an artificial vibration of a predetermined frequency or higher in at least one axial direction, a cooking device having a configuration for disabling the thermal power suppression control is provided.

When the contact information is received by the device-side wireless communication means in the state where the cooking utensil is detected by the cooking utensil detecting means, it can be determined that the user is touching the cooking utensil on the burner. On the other hand, the operation of shaking the pot, the operation of raising the pot, and the operation of taking out the pot are started by the user grasping the cooking utensil placed on the burner. Therefore, if the position information of the cooking utensil is initialized based on the position when the user is touching the cooking utensil placed on the burner, the acceleration information applied to the cooking utensil can be determined more accurately. ..

Preferably, in the above-mentioned cooking apparatus,
When the device-side control means includes artificial vibration of a predetermined frequency or higher in at least one axial direction in the acceleration information received by the device-side wireless communication means during the execution of the thermal power suppression control, the thermal power suppression control is invalidated. It has a configuration that returns the thermal power of the burner to the thermal power immediately before the thermal power suppression control is executed.

In a cooking device in which the heat suppression control is executed when the cookware detection means detects that the cookware is not placed on the burner, the burner is extinguished or the burner is extinguished by the user moving the cookware from the burner. The firepower is reduced.
However, according to the above-mentioned cooking apparatus, if the acceleration information received by the device-side wireless communication means during the execution of the thermal power suppression control includes an artificial vibration of a predetermined frequency or higher in at least one axial direction, the thermal power suppression Since the control is invalidated and the burning power of the burner is returned to the heating power immediately before the heating power suppression control is executed, for example, the user lifts the cooking utensil and cooks with the cooking utensil detecting means in order to start the operation such as shaking the pot. Even if the imposition of the utensil is detected and the burning power of the burner is temporarily suppressed, the user performs an operation such as shaking the pot to detect artificial vibration above the specified frequency and cook with the specified heating power. Can be continued.

Preferably, in the above-mentioned cooking apparatus,
The device-side control means includes artificial vibrations of a predetermined frequency or higher in any axial direction in the acceleration information received by the device-side wireless communication means for a certain period of time in a state where the thermal power suppression control is disabled. If not, it has a configuration to cancel the invalidation of the thermal power suppression control.

According to the above-mentioned cooking device, the acceleration information received by the device-side wireless communication means includes artificial vibration of a predetermined frequency or higher in any axial direction for a certain period of time in a state where the thermal power suppression control is disabled. If this is not the case, the invalidity of the heat suppression control is canceled. For example, when the cooking utensil is placed under the pot, the cooking utensil detection means executes the heating power suppression control to execute the burning power of the burner. Is suppressed. Therefore, it is possible to prevent the burner from burning due to a large open flame for a long time after the operation such as shaking the pot is stopped. On the other hand, when the cooking utensil is placed on the burner, the predetermined heating power is maintained, so that the workability of cooking is not impaired.
In addition, even if no artificial vibration above a predetermined frequency is detected when the cooking utensil is not placed on the burner, the heating power suppression control will continue to be disabled for a certain period of time. It is possible to avoid suppressing the heating power when shifting to the shaking operation or when the operation such as shaking the pot is temporarily interrupted to check the cooking state of the cooked food.

Preferably, in the above-mentioned cooking apparatus,

When displacement is included, it has a configuration to cancel the invalidation of the thermal power suppression control.

As described above, the operation of raising the pot is different from the operation of shaking the pot, and the cooking utensil is moved linearly in a certain direction. When such an operation such as raising a pot is performed, if the thermal power suppression control is continuously disabled, the burning of the burner is continued with a large open flame.
However, according to the above-mentioned cooking apparatus, in a state where the thermal power suppression control is disabled, only one of the positive direction and the negative direction in the axial direction of the acceleration information received by the device-side wireless communication means is available. If a displacement in the direction of Will be done. Therefore, it is possible to ensure safety when an operation such as raising a pot is being performed.

Preferably, in the above-mentioned cooking apparatus,
The device-side control means has a configuration for extinguishing a fire when the acceleration information received by the device-side wireless communication means includes an inclination of at least a predetermined angle in one axial direction.

When the cookware is taken out from the cookware at the end of cooking, the user may tilt the cookware so that the cookware can be easily taken out. Since this take-out operation may be performed on the burner or in the vicinity of the burner, there is a problem that the flame of the burner overflows from the periphery of the cooking utensil or the cooked food is overheated.
However, according to the above-mentioned cooking apparatus, if the acceleration information received by the device-side wireless communication means includes an inclination of at least a predetermined angle in one axial direction, the burner is extinguished. It is possible to improve the safety when the operation is performed and to prevent the cooking from overheating.

Is provided with a thermista 507 that detects the temperature of the cooking utensil P. A battery 501, an acceleration detection unit 502, a contact detection unit 503, an instrument side wireless communication unit 504, and a thermistor 507 are electrically connected to the instrument side control means 500, and the instrument side antenna 505 is connected to the instrument side wireless communication. It is connected to the unit 504. The temperature detected by the thermistor 507 is output to the instrument-side control means 500. Therefore, the thermistor 507 functions as an instrument-side temperature detection unit.

The acceleration detection unit 502 detects accelerations in the three axial directions of XYZ orthogonal to each other, and outputs the detected acceleration information to the instrument side control means 500. The acceleration detection unit 502 is preferably capable of digitally outputting an acceleration signal by on-board serial communication such as an I2C (Inter-Integrated Circuit) mode or an SPI (Serial Peripheral Interface) mode.

The acceleration detection unit 502 can use, for example, a piezo resistance type or capacitance type acceleration sensor, detects various accelerations applied to the cooking utensil P by the user, and has a level corresponding to the accelerations. Acceleration information is derived and output to the instrument side control means 500.

For example, when the user is performing an operation such as shaking a pot on the stove burner 32, vibration is periodically applied to the cooking utensil P in the positive and negative directions in at least one axial direction, and the acceleration information changes. Occurs. Further, when the user is performing the operation of raising the pot to lift the cooking utensil P from above the stove burner 32, the cooking utensil P is subjected to vibration with less periodicity in the negative direction at least in the Z-axis direction and is constant. A displacement of the distance is applied, causing a change in the acceleration information. Further, when the cooking utensil P is operated to move from the top of the stove burner 32 onto the top plate 30 or the counter top, the cooking utensil P is in the positive direction at least in the X-axis or Y-axis direction parallel to the top plate 30. Alternatively, vibration with less periodicity is applied in any one of the negative directions, and a displacement of a certain distance is applied, resulting in a change in acceleration information.

Further, by providing the acceleration detection unit 502 that can acquire the acceleration in the three axial directions, the inclination of the cooking utensil P in each direction can be detected. For example, when the user tilts the cooking utensil P to take out the cooked food from the cooking utensil P at the end of cooking, the acceleration information is changed by the rotational motion in at least one axial direction. Therefore, by detecting the acceleration information applied to the cooking utensil P by the operation of the user, the state of the cooking utensil P during cooking or at the end of cooking can be determined, and the thermal power of the stove burner 32 can be accurately determined accordingly. Can be controlled.

The contact detection unit 503 can use, for example, a capacitance detection sensor that detects a change in the capacitance on the surface of the handle portion P2 by the user touching the handle portion P2, and uses the detected contact information on the instrument side. It is output to the control means 500. In addition, another contact sensor such as a pressure sensor or a temperature sensor may be used as the contact detection unit 503.

Although not shown, the utensil-side control means 500 includes a control circuit including a storage device in which a control program and various data are stored, a timer, and a microcomputer for controlling the operation of the entire cooking utensil P. Further, the instrument-side control means 500 generates various signals based on the acceleration information, contact information, and temperature information output from the acceleration detection unit 502, the contact detection unit 503, and the thermistor 507, respectively, and the instrument-side wireless communication unit 500. Communicate to 504. The instrument-side wireless communication unit 504 converts various signals generated by the instrument-side control means 500 into wireless signals and wirelessly transmits them from the instrument-side antenna 505 toward a predetermined transmission area. This information is transmitted to the device-side wireless communication unit 404 via the device-side antenna 405, and is used for controlling the stove burner 32 by the device-side control means 400. Further, the device-side wireless communication unit 504 receives the radio signal transmitted from the device-side antenna 405 described above via the device-side antenna 505, demodulates the received signal, and outputs the received signal to the device-side control means 500.

FIG. 3 shows the measurement results of the acceleration information applied to the cooking utensil P when the cooking utensil P according to the present embodiment performs the operation of shaking the pan and the operation of lowering the pan in the front-rear direction of the gas stove. , (A) is a vibration waveform diagram in the Y-axis direction and its vibration spectrum when the operation of shaking the pot is performed, and (b) is a vibration waveform diagram in the Y-axis direction when the operation of lowering the pot is performed. And its vibration spectrum. FIG. 3 shows the measurement results only in the Y-axis direction in order to compare the acceleration information in the moving direction of the cooking utensil P, but weak vibrations are also observed in the X-axis direction and the Z-axis direction. In the frequency analysis, the acceleration signal is processed by a microcomputer using a fast Fourier transform.

In the operation of shaking the pot shown in FIG. 3A, the cooking utensil P is repeatedly moved in the front-back direction, so that vibrations are observed in the positive and negative directions in the vibration waveform diagram, and a constant frequency (for example, in frequency analysis) is observed in the vibration waveform diagram. Periodic artificial vibrations of 2 Hz) or higher are observed. Although not shown, for example, in the pan-shaking operation of moving the cooking utensil P in the front-back and up-down directions, periodic artificial vibrations having a constant frequency or higher mainly in the Y and Z-axis directions are observed. On the other hand, in the pan-lowering operation shown in FIG. 3B, the cooking utensil P is moved from the front side to the back side in the Y-axis direction, and therefore, in the vibration waveform diagram, it is mainly in the negative direction. In the frequency analysis, only the artificial vibration with a lower frequency than the vibration observed in the operation of shaking the pot is observed. As described above, all the vibrations are artificial vibrations applied to the cooking utensil P by the operation of the user, but as can be understood from the frequency analysis of FIG. 3, in the operation that does not require the suppression of the thermal power such as the shaking of the pot. , Anthropogenic vibrations with a higher frequency than the operation of raising the pot are observed. Therefore, when the acceleration information applied to the cooking utensil P is frequency-analyzed and an artificial vibration of a predetermined frequency or higher is detected, even if the cooking utensil P is not detected by the cooking utensil detection unit 320, the thermal power suppression control is performed. If is disabled, cooking can be continued with appropriate heat. Further, when the acceleration information includes artificial vibrations having a frequency lower than a predetermined frequency, safety can be ensured by executing the thermal power suppression control.

FIG. 4 is a measurement result of acceleration information applied to the cooking utensil P when the cooking utensil P according to the present embodiment is tilted and taken out, and FIG. 4A is a temporal time in the X-axis direction. A change diagram is shown, (b) shows a temporal change diagram in the Y-axis direction, and (c) shows a temporal change diagram in the Z-axis direction. In the extraction operation shown in FIG. 4, the signal is tilted clockwise in the axial direction of the Y axis, so that the signal is not substantially observed in the Y axis direction, and the signal is observed in the X and Z axis directions. The inclination can be calculated based on the acceleration in each axial direction. For example, in FIG. 4, the absolute value (Gz) of the change in acceleration in the X-axis direction from rest is about 8.4 m / s ² , and the absolute value of the change in acceleration in the Z-axis direction from rest (Gx). ) Is about 4.6 m / s ² , so the tan θ in the XZ axis direction is about 1.82 (Gz / Gx), and it is calculated that the inclination of the cooking utensil is about 60 degrees. NS. As described above, when the inclination of the predetermined angle or more is detected based on the acceleration information applied to the cooking utensil P, the stove burner 32 can be extinguished to improve the safety and the stove burner 32. You can prevent the food from overheating on it.

Next, an example of the control operation in the case of cooking in the cooking system including the gas stove 1 and the cooking utensil P of the present embodiment will be described with reference to FIGS. 5 and 6.
After the power switch 29 of the gas stove 1 is turned on, when the user grips the handle portion P2 of the cooking utensil P and the contact detection unit 503 detects that the user touches the cooking utensil P, the appliance The side control means 500 starts the transmission of the radio signal from the instrument side radio communication unit 504 (step S1). As a result, it is not necessary to constantly perform wireless communication between the cooking utensil P and the gas stove 1, so that power saving can be achieved. Then, when the user approaches the gas stove 1 to a predetermined distance while gripping the grip portion of the cooking utensil P, a wireless link is established between the cooking utensil P and the gas stove 1.

Next, when the user places the cooking utensil P on the stove burner 32, the head portion 322 is pushed downward and the reed switch 327 is turned on. Then, when the ignition operation is performed by the point fire extinguishing operation unit 42, the device-side control means 400 outputs an ignition signal to the device-side wireless communication unit 404, and the device-side wireless communication unit 404 outputs a radio signal from the device-side antenna 405. Send. Then, the appliance-side wireless communication unit 504 that received the radio signal via the appliance-side antenna 505 demolishes the radio signal to the appliance-side control means 500 and outputs an ignition signal, and the appliance-side control means 500 is the cooking utensil P. Initialize the position information of (steps S2 to S4). Thereby, the acceleration information applied to the cooking utensil P can be determined based on the state at the start of cooking in which the cooking utensil P is placed on the substantially horizontal trivet 36.

Further, when the above ignition operation is performed, the opening degree of the flow rate adjusting valve 153 is adjusted to a predetermined opening degree at the time of ignition, spark discharge is generated from the spark plug 51, and the electromagnetic on-off valve 151 and the main valve 152 are further operated. The valve is opened. As a result, a mixed gas having a concentration suitable for ignition is released from the flame hole and ignited by the spark discharge. As a result, the stove burner 32 is ignited.

After the stove burner 32 is ignited, when the thermal power setting operation is performed by the point fire extinguishing operation unit 42, the opening degree of the flow rate adjusting valve 153 is changed according to the operation position, and the set thermal power is stored ( Step S5). Although not shown, in the present embodiment, a new set thermal power is stored every time the thermal power setting operation is performed by the point fire extinguishing operation unit 42, except when the thermal power suppression control is executed. Although it is configured, it may be configured so that only the thermal power immediately before the thermal power suppression control is executed is stored. Further, when the fire extinguishing operation is performed by the point fire extinguishing operation unit 42 regardless of whether the thermal power suppression control is executed or disabled, the main valve 152 is closed and the stove burner 32 is extinguished.

When the stove burner 32 is ignited as described above, the determination of the acceleration information received from the cooking utensil P is started, and the cooking utensil P has a predetermined angle R (for example, 60 degrees) in at least one axial direction based on the acceleration information. As described above, it is determined whether or not the tool is tilted (step S6). At this time, if the cooking utensil P is tilted by a predetermined angle R or more in at least one axial direction, it is highly possible that the cooked food has been taken out, so the stove burner 32 is extinguished (step S25). As a result, even when the taking-out operation is performed on the stove burner 32, the user's hand is not roasted by the flame overflowing from the peripheral edge of the cooking utensil P. In addition, the cooked food in the cooked utensil P that has been cooked is not overheated.

On the other hand, when the cooking utensil P is not tilted by a predetermined angle R or more in at least one axial direction (No in step S6), the acceleration information received from the cooking utensil P has a predetermined frequency f (for example, for example) in at least one axial direction. It is determined whether or not an artificial vibration of 2 Hz) or higher is included (step S7).

At this time, when the acceleration information received from the cooking utensil P includes an artificial vibration having a predetermined frequency f or higher (Yes in step S7), the cooking utensil P is detected by the cooking utensil detection unit 320. Since it is considered that the user periodically operates the cooking utensil P in at least one axial direction, the thermal power suppression control is performed so as not to determine whether the cooking utensil P is mounted / not mounted by the lead switch 327. Is disabled, a timer for measuring a predetermined standby time t1 (for example, 5 seconds) is started, and the thermal power of the controller 32 is maintained at the set thermal power (steps S8 to S10). This makes it possible to prevent fluctuations in the thermal power of the stove burner 32 when the head portion 322 moves up and down during the operation of shaking the pan. Further, when the operation of shaking the pot is detected and the thermal power suppression control is invalidated, the set thermal power is maintained. Therefore, in order to set the thermal power of the stove burner 32 to a predetermined thermal power again, the point fire extinguishing operation unit 42 There is no need to operate. Further, even when the cooking utensil P is lifted in order to shift to the operation of shaking the pot after the operation of shaking the pot, the heating power of the stove burner 32 is not suppressed, and cooking can be continued at the set heating power. Therefore, it is not necessary to perform another operation for canceling the heating power suppression control during cooking. As a result, the workability of cooking can be significantly improved.

While the thermal power suppression control is disabled, it is determined whether or not the cooking utensil P is tilted by a predetermined angle R or more in at least one axial direction based on the acceleration information received from the cooking utensil P, and cooking is performed in the same manner as described above. When the appliance P is tilted by a predetermined angle R or more, the stove burner 32 is extinguished (steps S11 and S25). As a result, safety at the time of taking out can be ensured. Further, when the acceleration information received from the cooking utensil P does not include a inclination of a predetermined angle R or more, but includes an artificial vibration of a predetermined frequency f or more (in step S11, No, in step S12, Yes), a new timer is started to measure the new standby time t1 and the invalidation of the thermal power suppression control is continued (step S14).

When the user stops the operation such as shaking the pot and the acceleration information received from the cooking utensil P does not include the artificial vibration of the predetermined frequency f or higher (No in step S12), the predetermined standby time t1 is set. The invalidation of the thermal power suppression control is continued until the elapse (step S13). In this way, even if artificial vibration above a predetermined frequency f due to the operation of the pot shaking or the like is no longer observed, by disabling the thermal power suppression control for a certain period of time, the user is in the middle of the operation of the pot shaking or the like. Temporarily moves the cookware P from the top of the stove burner 32 onto the top plate 30 in order to add food to the cookware P or remove a part of the cooked food from the cookware P, and then the pan. Even when the operation such as shaking is restarted, cooking can be continued with the set heat power. Further, even if the cooking utensil P is lifted at intervals for a certain period of time in order to shift to the operation of shaking the pot after the operation of shaking the pot, the thermal power suppression control is invalid until the predetermined waiting time t1 elapses. Therefore, even if the cooking utensil P is lifted on the stove burner 32 after the operation of shaking the pot, it is possible to prevent the heating power of the stove burner 32 from being suppressed. This makes it possible to further improve the workability of cooking. When the cooking utensil P is tilted by a predetermined angle R or more in a state where the thermal power suppression control is disabled, the stove burner 32 is extinguished without waiting for the elapse of the predetermined waiting time t1 (step S11). And S25), the safety in the operation of taking out at the end of cooking can be further improved.

Even after the predetermined standby time t1 has elapsed, if the acceleration information received from the cooking utensil P does not include the artificial vibration of the predetermined frequency f or higher, the invalidation of the thermal power suppression control is canceled (step S15). This makes it possible to prevent the stove burner 32 from continuing to burn due to a large open flame for a long time.

Further, when the non-placement of the cooking utensil P is detected by the signal output from the reed switch 327, the timer is started to measure the predetermined elapsed time t2 (for example, 1 minute), and the heating power suppression control is performed. Executed, the thermal power of the controller 32 is changed to a predetermined limit thermal power (for example, the minimum thermal power) (steps S16 to S18).

While the thermal power suppression control is being executed, it is determined whether or not the cooking utensil P is tilted by a predetermined angle R or more in at least one axial direction based on the acceleration information received from the cooking utensil P. When P is tilted by a predetermined angle R or more, the stove burner 32 is extinguished (steps S19 and S25). As a result, safety at the time of taking out can be ensured. Further, when the acceleration information received from the cooking utensil P does not include a inclination of a predetermined angle R or more, but includes an artificial vibration of a predetermined frequency f or more (in step S19, No, in step S20, Yes), the heating power suppression control is invalidated, the heating power of the stove burner 32 is returned to the set heating power immediately before the heating power suppression control is executed, and cooking is continued.

If the placement of the cooking utensil P is detected by the time when the predetermined elapsed time t2 elapses during the execution of the thermal power suppression control (No in step S21, Yes in step S22), the thermal power of the stove burner 32 is set. And continue cooking (step S23).

Further, during the execution of the thermal power suppression control, the acceleration information received from the cooking utensil P does not include the inclination of the predetermined angle R or more, and the artificial frequency f or more is artificial until the predetermined elapsed time t2 elapses. If the vibration is not included (No in steps S19 and S20, Yes in step S21), the controller 32 is extinguished with an error (step S24). As a result, it is possible to prevent the stove burner 32 from burning on an open flame for a long time when the cooking utensil P is not placed on the stove burner 32. Further, even if vibration is generated by an operation such as raising a pan, the heating power of the stove burner 32 is not changed to the set heating power unless the acceleration information received from the cooking utensil P includes artificial vibration having a predetermined frequency f or higher. Therefore, the user is not surprised by the careless change of the firepower.

As described above, according to the gas stove 1 of the present embodiment, when the cooking utensil P is not placed on the stove burner 32, the heating power suppression control for suppressing the heating power of the stove burner 32 is executed, but it is used. Since the acceleration information applied to the cooking utensil P when the person operates the cooking utensil P is detected and it is determined whether or not the thermal power suppression control is invalidated based on the acceleration information, cooking is performed with an appropriate thermal power. Can be done. Therefore, according to the gas stove 1 of the present embodiment, the workability of cooking can be improved and the safety can be improved.

(Other embodiments)
(1) In the above embodiment, the case where the cooking apparatus controls the burning power of the burner based on the acceleration information received from the cooking utensil has been described, but the heating power of the burner is further controlled based on the cooking utensil side temperature information received from the cooking utensil. You may control it. According to this, even if the cooking utensil is separated from the burner due to the operation such as shaking the pot and the temperature of the cooking utensil cannot be directly detected on the cooking utensil side, the heating power is appropriately controlled based on the received utensil side temperature information. Can be done. In addition, when cooking is completed and the cooking utensil is moved from the top of the burner by an operation such as raising a pot when the thermal power suppression control is disabled, the burner is burning with a large thermal power, so the temperature detector on the device side The temperature detected by the temperature detector on the appliance side is lower than the temperature detected by, and the temperature difference between the two becomes large. Therefore, it is possible to determine the end of cooking based on the received temperature information on the appliance side, and higher safety can be ensured. Further, when automatic cooking is being performed, the heating power of the burner can be controlled based not only on the temperature information on the device side but also on the temperature information on the appliance side.
(2) In the above embodiment, when the burner is ignited while the cooking utensil detection unit has detected the placement of the cooking utensil, the position information of the cooking utensil is initialized, but the position information of the cooking utensil is initialized. The initialization may be performed when contact information is received from the cooking utensil while the cooking utensil detection unit has detected the placement of the cooking utensil on the burner. That is, the operation of shaking the pot, the operation of raising the pot, and the operation of taking out the pot are started by the user grasping the cooking utensil placed on the burner. Therefore, if the position information of the cooking utensil is initialized based on the position when the user is touching the cooking utensil on the burner, the acceleration information applied to the cooking utensil can be determined more accurately.
(3) In the above embodiment, when the burner is ignited while the cooking utensil detection unit has detected the placement of the cooking utensil, the cooking utensil is made to transmit an ignition signal to initialize the position information of the cooking utensil. However, based on the acceleration information received from the cooking utensil, the position information of the cooking utensil may be initialized by the control means on the device side without transmitting the ignition signal.
(4) In the above embodiment, when the acceleration information received from the cooking utensil does not include artificial vibration of a predetermined frequency or more, the end of cooking is determined from whether the cooking utensil is tilted by a predetermined angle or more. However, the acceleration information received from the cookware independently or in conjunction with the tilt of the cookware includes displacement in either the positive or negative direction in any one axial direction. The end of cooking may be determined based on whether or not the cooking is completed. According to this, when the cooking utensil is moving in the positive direction or the negative direction in at least one of the axial directions due to the operation such as raising the pot, the heating power is limited, so that the cooking utensil is placed on the burner. It is possible to prevent the combustion from continuing due to a large open flame when it is not in use.
