JP 2017-40430 A

  In Patent Literature 1, the size of an object to be heated is specified by using an ultrasonic sensor, and the protrusion of a flame from the object to be heated is suppressed. However, an error may occur between the size of the heating target specified using the ultrasonic sensor and the actual size of the heating target. For this reason, when the size of the heating target is specified to be larger than the actual size of the heating target, the flame may greatly protrude from the outline of the heating target.

  It is an object of the present specification to provide a cooking system that is excellent in safety.

  The heating cooking system disclosed in this specification includes a heating cooker that heats an object to be heated, and a detection unit that detects an outline and a flame of the object to be heated. The heating cooker includes a burner that heats the object to be heated using gas, an ignition unit that ignites the burner, an ignition operation unit that is operated by a user to ignite the burner, the burner, Control means for controlling the operation of the ignition means, wherein the control means supplies a first predetermined gas amount to the burner when the ignition operation means is operated, so that The burner is ignited so that the flame does not protrude to the outside, and after igniting the burner, the gas supply amount, which is the amount of gas supplied to the burner, is increased in a stepwise manner, so that the flame is outside the contour. When it is detected that the gas has protruded, the increase in the gas supply amount is stopped.

  According to the above configuration, the control means ignites the burner so that the flame does not protrude outside the contour. Then, after igniting the burner, the control means increases the gas supply amount stepwise, and stops increasing the gas supply amount when detecting that the flame has protruded outside the contour of the object to be heated. . Since the gas supply to the burner is increased stepwise after the burner is ignited, it is possible to detect early that the flame protrudes outside the contour of the object to be heated. For this reason, the amount of the flame protruding from the outline of the object to be heated can be reliably reduced. Therefore, the safety of the heating cooking system can be improved.

  In addition, the heating cooking system may include a temperature detection unit that detects an object temperature that is the temperature of the object to be heated. The control means, when the target temperature when the ignition operation means is operated is lower than a predetermined temperature, after igniting the burner, increases the gas supply amount stepwise, and performs the operation when the ignition operation means is operated. When the temperature of the object is equal to or higher than the predetermined temperature, the gas supply amount may not be increased stepwise after the burner is ignited.

  The case where the temperature of the object when the ignition operating means is operated is equal to or higher than the predetermined temperature is the case where the object to be heated is reheated. In this case, even if the gas supply amount to the burner is small, the object to be heated can be sufficiently heated. According to the above configuration, the control unit does not stepwise increase the gas supply amount after igniting the burner when the target temperature when the ignition operation unit is operated is lower than the predetermined temperature. Therefore, in a situation where it is not necessary to increase the gas supply amount to the burner, the gas supply amount to the burner can be suppressed.

  The control means detects that the flame has protruded outside the contour, stops the increase in the gas supply amount, then gradually reduces the gas supply amount, and confirms that the flame has not protruded outside the contour. When detecting, the decrease in the gas supply amount may be stopped.

  If the gas supply is gradually increased and the increase of the gas supply is stopped when it is detected that the flame has protruded outside the outline of the object to be heated, the flame is slightly shifted from the outline of the object to be heated. It protrudes. According to the above configuration, at the time when the reduction of the gas supply amount is stopped, the flame does not protrude from the contour of the object to be heated, and is located slightly inside the contour of the object to be heated. Therefore, it is possible to reliably prevent the flame from protruding from the contour of the object to be heated, and to suppress waste of thermal energy.

  The control means detects that the flame protrudes outside the temperature contour of the object, stops increasing the supply amount of the object temperature gas, and then reduces the supply amount of the object temperature gas by the second predetermined gas amount. May be.

  If the gas supply is gradually increased and the increase of the gas supply is stopped when it is detected that the flame has protruded outside the outline of the object to be heated, the flame is slightly shifted from the outline of the object to be heated. It protrudes. According to the above configuration, by reducing the gas supply amount by the second predetermined gas amount, the flame does not protrude from the contour of the heating target and is located slightly inside the contour of the heating target. State. Therefore, it is possible to reliably prevent the flame from protruding from the contour of the object to be heated, and to suppress waste of thermal energy.

  The control means, when detecting that the flame protrudes outside the contour, stops increasing the gas supply amount, stores the gas supply amount when the gas supply amount is stopped as a limited gas supply amount, Until the burner is extinguished, the limiting operation for limiting the gas supply amount to the limited gas supply amount or less may be executed.

  According to the above configuration, the control unit executes the limited operation of limiting the gas supply amount supplied to the burner to the limited gas supply amount or less until the burner is extinguished. For this reason, even if an operation for supplying a gas exceeding the limited gas supply amount to the burner is operated by the user, the gas supply amount supplied to the burner is limited to the limited gas supply amount. Therefore, it is possible to prevent the flame from protruding from the contour of the object to be heated by the operation of the user.

  The heating cooker may include a restriction release operation unit for releasing the restricted operation. The control means may stop the limited operation when the restriction release operation means is operated during the limited operation.

  According to the above configuration, the control unit stops the limited operation when the restriction release operation unit is operated during the limited operation. Depending on the cooking method, it may be desired to make the flame protrude from the outline of the object to be heated. Therefore, when the user desires to cause the flame to protrude from the contour of the heating object, the user can operate the restriction release operation means to cause the flame to protrude from the contour of the heating object. Convenience can be improved.

  The detection means may be arranged above the burner.

  When the detection means is arranged, for example, on the side of the burner, it is difficult to accurately grasp the outermost part of the flame and the contour of the object to be heated. According to the above configuration, the detecting means can accurately grasp the outermost part of the flame. Therefore, the control means can reliably determine that the flame has protruded from the contour of the object to be heated.

(Heat treatment; FIG. 4)
Subsequently, a heating process performed by the control unit 80 of the heating cooker 2 will be described with reference to FIG. When the power of the heating cooker 2 is turned on, the control unit 80 starts the heating process.

  In S10, the control unit 80 monitors that any one of the heating amount operation units 42a, 42b, and 42c performs an ignition operation. When any one of the heating amount operation units 42a, 42b, and 42c performs the ignition operation, the control unit 80 determines YES in S10, and the process proceeds to S12. Hereinafter, a case where an ignition operation is performed on the heating amount operation unit 42a will be described as an example.

  In S12, the control unit 80 transmits a shooting start signal to the range hood 100. The shooting start signal is a signal requesting transmission of image data shot by the camera 104a of the range hood 100. When the range hood 100 receives the photographing start signal from the cooking device 2, the range hood 100 starts transmitting image data photographed by the camera 104a to the cooking device 2. Range hood 100 continues to transmit image data to heating cooker 2 until receiving a shooting end signal from heating cooker 2.

  In S14, the control unit 80 causes the stove burner 10a to ignite. Specifically, the control unit 80 supplies the first predetermined gas amount to the stove burner 10a and operates the igniter to ignite the stove burner 10a. The first predetermined gas amount is set based on the minimum diameter of the heating object 200 generally placed on the gorge 8a. In the present embodiment, the first predetermined gas amount is such that when the diameter of the heating object 200 supported by the virtue 8a is 12 cm, the flame 210 when igniting protrudes from the outline 202 of the heating object 200. No gas supply is preset. Therefore, at this time, the flame 210 does not protrude from the outline 202 of the heating object 200 (see FIG. 6A).

  In S20, the control unit 80 determines whether the target object temperature, which is the temperature of the heating target 200 detected by the sensor 12a, is lower than a predetermined temperature (for example, 80 ° C.). When the target object temperature is lower than the predetermined temperature, control unit 80 determines YES in S20, and the process proceeds to S22. On the other hand, if the target object temperature is equal to or higher than the predetermined temperature, control unit 80 determines NO in S20, and the process proceeds to S40.

  In S22, the control unit 80 increases the gas supply amount supplied to the stove burner 10a by a third predetermined gas amount. The third predetermined gas amount is a relatively small gas amount.

  In S <b> 24, control unit 80 determines whether or not flame 210 protrudes outside contour 202 of heating target 200 using image data received from range hood 100. When the flame 210 protrudes outside the outline 202, the control unit 80 determines YES in S24, and the process proceeds to S26. On the other hand, when the flame 210 does not protrude outside the outline 202, the control unit 80 determines NO in S24, and the process returns to S22. That is, the control unit 80 gradually increases the gas supply amount to the stove burner 10a until YES is determined in S24.

  In S26, the control unit 80 stops increasing the gas supply amount to the stove burner 10a. At this point, the flame 210 slightly protrudes outside the outline 202 of the heating object 200 (see FIG. 6B).

  In S28, the control unit 80 causes the memory 82 to store the gas supply amount at the time when the increase in the gas supply amount to the stove burner 10a is stopped as the limited gas supply amount. Hereinafter, the thermal power of the stove burner 10a in a state where the limited gas supply amount is supplied may be referred to as “limited thermal power”.

  In S30, the control unit 80 reduces the gas supply amount supplied to the stove burner 10a by a fourth predetermined gas amount. The fourth predetermined gas amount is a relatively small gas amount.

  In S <b> 32, control unit 80 determines whether or not flame 210 protrudes outside outline 202 of heating target 200 using image data received from range hood 100. When the flame 210 does not protrude outside the outline 202, the control unit 80 determines NO in S32, and the process proceeds to S34. On the other hand, when the flame 210 protrudes outside the outline 202, the control unit 80 determines YES in S32, and the process returns to S30. That is, the control unit 80 continues to decrease the gas supply amount to the stove burner 10a in a stepwise manner until NO is determined in S32.

  In S34, the control unit 80 stops decreasing the gas supply amount to the stove burner 10a. The control unit 80 further transmits a shooting end signal to the range hood 100 in S34. When range hood 100 receives the photographing end signal from heating cooker 2, range hood 100 ends transmission of image data to heating cooker 2. At this point, the flame 210 is located slightly inside the outline 202 of the heating object 200 (see FIG. 6C).

  In S36, the control unit 80 changes the heating power restriction flag 86 from “OFF” to “ON”.

  In S40, control unit 80 executes a thermal power adjustment process. The heating power adjustment processing is processing for adjusting the heating power of the stove burner 10a in accordance with an operation performed on the heating amount operation unit 42a by the user. When S40 ends, the processing in FIG. 4 ends.

(Thermal power adjustment processing; FIG. 5)
Subsequently, the heating power adjustment processing executed in S40 of FIG. 4 will be described.

  In S60, the control unit 80 monitors that the heating power adjustment operation is performed on the heating amount operation unit 42a. The control unit 80 determines YES in S60 when the heating power adjustment operation is performed on the heating amount operation unit 42a, and proceeds to S62.

  In S62, the control unit 80 determines whether or not the heating power restriction flag 86 in the memory 82 is "ON". When the thermal power restriction flag 86 is “ON”, the control unit 80 determines YES in S62, and the process proceeds to S64. On the other hand, when the heat power restriction flag 86 is “OFF”, the control unit 80 determines NO in S62, and the process proceeds to S70.

  In S64, control unit 80 determines whether or not the heating power set by the user (hereinafter referred to as “set heating power”) exceeds the limited heating power. Specifically, the control unit 80 specifies the gas supply amount corresponding to the set thermal power, and determines whether or not the specified gas supply amount exceeds the limited gas supply amount in the memory 82. When the specified gas supply amount exceeds the limited gas supply amount, control unit 80 determines YES in S64, and the process proceeds to S66. On the other hand, when the specified gas supply amount is equal to or smaller than the limited gas supply amount, the control unit 80 determines NO in S64, and the process proceeds to S68.

  In S66, the control unit 80 adjusts the heating power of the stove burner 10a to the limited heating power. Specifically, the control unit 80 adjusts the opening of the flow control valve so that the gas supply amount supplied to the stove burner 10a becomes the limited gas supply amount. When S66 ends, the process returns to S60.

  On the other hand, in S68, the control unit 80 adjusts the heating power of the stove burner 10a to the set heating power. Specifically, control unit 80 adjusts the opening of the flow control valve so that the gas supply amount supplied to stove burner 10a becomes a gas supply amount corresponding to the set thermal power. When S68 ends, the process returns to S60. The processes executed in S66 and S68 are the processes executed in the limited operation.

  If NO is determined in S62, the control unit 80 adjusts the heating power of the stove burner 10a to the set heating power in S70 without executing the processing of S64. That is, the heating power of the stove burner 10a is not limited to the limited heating power. When S70 ends, the process returns to S60. The process executed in S70 is a process executed in normal operation.

  In addition, in S80, the control unit 80 monitors, at the same time as the monitoring in S60, that the limit release operation, which is an operation for releasing the restricted operation, is executed by the stove setting operation unit 48a. When the restriction release operation is performed, control unit 80 determines YES in S80, and the process proceeds to S82.

  In S82, the control unit 80 changes the heating power restriction flag 86 from “ON” to “OFF”. Thereby, the control unit 80 stops the limited operation and performs the normal operation. Therefore, in the subsequent processing, the control unit 80 determines NO in S62. When S82 ends, the process returns to S60.

  In S90, the control unit 80 monitors that the fire extinguishing operation is performed on the heating amount operation unit 42a simultaneously with the monitoring in S60 and S80. When the fire extinguishing operation is performed on the heating amount operation unit 42a, the control unit 80 determines YES in S90, and proceeds to S92.

  In S92, the control unit 80 stops gas supply to the stove burner 10a and extinguishes the stove burner 10a.

  In S94, the control unit 80 changes the heating power restriction flag 86 from "ON" to "OFF". Note that if the thermal power restriction flag 86 is “OFF” at the time of S92, the controller 80 omits S94. When S94 ends, the processing in FIG. 5 ends. In a modification, the control unit 80 may execute the process of changing the heating power restriction flag 86 from “ON” to “OFF” between S10 and S20 in FIG.

  As described above, the control unit 80 ignites the stove burner 10a so that the flame 210 does not protrude outside the outline 202 of the heating target 200 (S14 in FIG. 4). Then, immediately after the ignition of the stove burner 10a, the control unit 80 gradually increases the gas supply amount to the stove burner 10a (S22 in FIG. 4), and the flame 210 protrudes outside the outline 202 of the heating object 200. When it is detected (YES in S24 of FIG. 4), the increase of the gas supply amount is stopped (S26 of FIG. 4). Immediately after the ignition of the stove burner 10a, the gas supply amount to the burner is increased stepwise, so that it is possible to detect early that the flame 210 protrudes outside the outline 202 of the heating object 200. Therefore, the amount of the flame 210 protruding from the outline 202 of the heating object 200 can be reliably reduced. Therefore, the safety of the heating cooking system 1 can be improved.

  Further, when the temperature of the target object when the ignition operation is performed on the heating amount operation unit 42a is lower than the predetermined temperature (YES in S20 of FIG. 4), the control unit 80 increases the gas supply amount stepwise. (S22 in FIG. 4), when the target object temperature is lower than the predetermined temperature (NO in S20 in FIG. 4), the gas supply amount is not increased stepwise. The case where the object temperature is lower than the predetermined temperature is a case where the heating object 200 is reheated. In this case, the heating target 200 can be sufficiently heated even if the gas supply amount to the stove burner 10a is small. Therefore, in a situation where it is not necessary to increase the gas supply amount to the stove burner 10a, the gas supply amount to the stove burner 10a can be suppressed.

  Further, after stopping the increase in the gas supply amount, the control unit 80 gradually reduces the gas supply amount (S30 in FIG. 4), and the flame 210 does not protrude outside the outline 202 of the heating target 200. If it is detected (NO in S32 of FIG. 4), the reduction of the gas supply amount is stopped (S34 of FIG. 4). The gas supply amount was increased stepwise, and when it was detected that the flame 210 protruded outside the outline 202 of the heating object 200 (YES in S24 of FIG. 4), the increase of the gas supply amount was stopped. In this case (S26 in FIG. 4), the flame 210 slightly protrudes from the outline 202 of the heating object 200 (see FIG. 6B). According to the above configuration, at the point in time when the decrease in the gas supply amount is stopped, the flame 210 does not protrude from the contour 202 of the heating target 200 and is positioned slightly inside the contour 202 of the heating target 200. (See FIG. 6C). Therefore, it is possible to reliably prevent the flame 210 from protruding from the outline 202 of the heating object 200 and to suppress waste of heat energy.

  In addition, the control unit 80 executes a limiting operation of limiting the gas supply amount supplied to the stove burner 10a to the limited gas supply amount or less until the stove burner 10a is extinguished (S64 to S68 in FIG. 5). For this reason, even if the user performs an operation for supplying a gas exceeding the limited gas supply amount to the burner (YES in S64 of FIG. 5), the gas supply amount supplied to the burner is limited to the limited gas supply amount. (S66 in FIG. 5). Therefore, it is possible to prevent the flame 210 from protruding from the outline 202 of the heating target 200 by a user operation.

  When the stove setting operation section 48a is operated during the limited operation (YES in S80 in FIG. 5), the control unit stops the limited operation (S82 in FIG. 5). Depending on the cooking method, it may be desired that the flame 210 protrudes from the outline 202 of the heating object 200. According to the above configuration, when the user wants the flame 210 to protrude from the outline 202 of the heating object 200, the user operates the stove setting operation unit 48a to move the flame 210 from the outline 202 of the heating object 200. It is possible to protrude, and the convenience for the user can be improved.

  The camera 104 is disposed above the cooking device 2. For example, when the camera 104 is arranged on the side of the cooking device 2, it is difficult to accurately grasp the outermost part of the flame 210 and the outline 202 of the heating target 200. By arranging the camera 104 above the cooking device 2, the control unit 80 accurately grasps the outermost part of the flame 210 and the outline 202 of the heating target 200 using image data captured by the camera 104. can do. Therefore, the control unit 80 can reliably determine that the flame 210 protrudes from the outline 202 of the heating target 200.

The camera 104 is an example of a “detection unit”. The stove burner 10 is an example of a “burner”. The igniter is an example of the “ignition unit”. The heating amount operation unit 42 is an example of “ignition operation means”. The control unit 80 is an example of a “control unit”. The sensor 12 is an example of a “temperature detecting unit”. The stove setting operation unit 48 is an example of a “limit release operation unit”.

  As mentioned above, although each Example was described in detail, these are only illustrations and do not limit a claim. The technology described in the claims includes various modifications and alterations of the specific examples illustrated above.

(First Modification) The range hood 100 may include an infrared sensor or an ultraviolet sensor instead of the camera 104. In this modification, the control unit 80 of the heating cooker 2 determines whether the flame 210 protrudes from the contour 202 of the heating target 200 using information detected by the infrared sensor and the ultraviolet sensor. .

(Second Modification) The heating target 200 may include a temperature sensor that detects the target temperature of the heating target 200. In this modified example, the sensor 12 may not be able to detect the target object temperature.

(Third Modification) In FIG. 4, S20 may be omitted. In the present modified example, the control unit 80 executes the processing after S22 regardless of the target object temperature when the ignition operation is performed on the heating amount operation unit 42a. That is, the "temperature detecting means" can be omitted.

(Fourth Modification) In the heating process of FIG. 4, instead of the processes of S30 to S34, the gas supply amount to the stove burner 10a may be reduced by a second predetermined gas amount. In this case, the second predetermined gas amount is set to a gas amount that can eliminate the protrusion of the flame 210 from the outline 202 of the heating target 200.

(Fifth Modification) The control unit 80 may not execute the limited operation. That is, S62 to S68 in FIG. 5 can be omitted.

(Sixth Modification) It is not necessary to release the limited operation until the stove burner 10 is extinguished. That is, the limited operation is always performed from the time when the limited gas supply amount is stored in the memory 82 to the time when the fire of the stove burner 10 is extinguished. In this modification, S70 and S72 in FIG. 5 can be omitted.

(Seventh Modification) The heating cooker 2 may include the camera 104. In addition, the camera 104 may be arranged on the side, below, or the like of the heating target 200.

  As described above, specific examples of the technology disclosed in this specification have been described in detail. However, these are merely examples, and do not limit the scope of the claims. The technology described in the claims includes various modifications and alterations of the specific examples illustrated above. In addition, the technical elements described in the present specification or the drawings exhibit technical utility singly or in various combinations, and are not limited to the combinations described in the claims at the time of filing.
