Description

The present invention relates to a heating cooker.

In a heating cooker such as a gas stove, whether or not the liquid in the cooking container heated by the heat source is in a boiling state is detected based on the detected value of the temperature of the cooking container, etc., and depending on the detection of the boiling state. It is conventionally known to stop the operation of a heat source, reduce the amount of output heat, or output notification information to a user (see, for example, Patent Documents 1 to 3).

In addition, in this type of cooking device, the boiling state detection timing varies due to the size and material of the cooking container containing the liquid to be heated, the amount of the liquid, the ingredients in the liquid, or the like. obtain. The boiling timing recognized by the user from the state of the liquid in the cooking container varies depending on the user. For this reason, the user may feel that the boiling state detection timing in the cooking device is too late or too early.

Therefore, for example, Patent Document 3 proposes that the user can delay or accelerate the detection timing of the boiling state in the heating cooker by performing a predetermined operation.

JP, 10-9576, A JP, 2014-31928, A JP, 2008-232560, A

In the technique disclosed in Patent Document 3, the user can adjust the detection timing of the boiling state, but since the frequency of the adjustment is generally low, the user does not know how to perform the adjustment. Or, I often don't remember. In this case, the user is required to check the instruction manual attached to the heating cooker, make an inquiry to the support center, and the like.

Also, the adjustment operation of the detection timing of the boiling state is complicated, or there is a case where it is not known how much the detection timing of the boiling state should be adjusted.In that case, the adjustment operation is performed by the user. It becomes annoying.

The present invention has been made in view of such a background, and an object of the present invention is to provide a heating cooker capable of reducing the burden on the user regarding the adjustment of the detection timing of the boiling state and improving the usability.

In order to achieve the above object, the heating cooker of the present invention is a state in which a heat source and a cooking container in which a liquid is put are being heated by the heat source, and the liquid in the cooking container is in a boiling state. A boiling detection unit that performs a boiling detection process that detects whether or not there is a predetermined boiling point, and a predetermined boiling response when the boiling state of the liquid in the cooking container is detected by the boiling detection unit. A heating cooker comprising a boiling-corresponding processing unit that executes processing,
During execution of the boiling detection process by the boiling detection unit, the presence or absence of a predetermined pre-detection event is monitored, and based on the presence or absence of the pre-detection event, the boiling state detection timing by the boiling detection unit is delayed. A detection delay determination unit that determines whether or not the state,
And a detection delay coping processing unit that executes a detection delay coping process related to the change of the judgment standard in the boiling detection process when the judgment result of the detection delay judgment unit is affirmative (first). invention).

Here, according to various studies of the inventor of the present application, when the boiling state detection timing by the boiling detection unit is delayed, the user stops the operation of the heat source before the boiling state is detected by the boiling detection unit. There is a tendency that a peculiar event (event) occurs due to a slow detection timing of the boiling state, such as a decrease in the amount of heat generated by the heat source or a spill of the liquid in the cooking container.

Therefore, in the first aspect of the present invention, the detection delay determination unit determines whether or not the boiling state detection timing by the boiling detection unit is in a delayed state, based on whether or not the pre-detection event has occurred. Thereby, when the detection timing of the boiling state is in a delayed state, it is possible to appropriately detect that.

Then, the detection delay handling processing unit, if the determination result of the detection delay determination unit is affirmative, that is, when it is detected that the detection timing of the boiling state is in the delayed state, in the boiling detection process The detection delay handling process regarding the change of the judgment standard is executed.

In this case, since the heating cooker executes the detection delay handling process, it is possible to reduce the user's time and effort for reducing the delay state of the detection timing of the boiling state.

Therefore, according to the cooking device of the first aspect of the present invention, it is possible to reduce the user's burden on adjusting the detection timing so as to reduce the delay state of the detection timing of the boiling state, and to improve the usability.

In the first aspect of the present invention, the boiling detection unit may be configured to be able to change the determination standard according to a predetermined operation of an operation unit included in the heating cooker. In this case, the detection delay response processing unit, the information indicating the determination result of the detection delay determination unit, and the operation unit for changing the determination criteria to reduce the delay state of the detection timing of the boiling state The process of notifying the user of at least one of the information indicating the operation method may be executed as the detection delay handling process (second invention).

According to this, the user can easily operate the operation unit so as to reduce the delay state of the detection timing of the boiling state, and the usability of the heating cooker can be appropriately improved.

Further, in the above-mentioned first invention, the detection delay handling processing section executes a process of automatically changing the judgment criterion as the detection delay handling process so as to reduce the delay state of the detection timing of the boiling state. Can be configured (third invention).

According to this, since the delay state of the detection timing of the boiling state is automatically reduced by the processing of the detection delay handling processing unit, the burden on the user can be effectively reduced. It is also possible to selectively perform the processing of the detection delay handling processing unit in the second invention and the processing of the detection delay handling processing unit in the third invention.

In the above-mentioned first to third inventions, the pre-detection event is the operation of the heat source in a state in which a detected value of the temperature of the cooking container has risen to a predetermined temperature or higher during the boiling detection process by the boiling detection unit. It is preferable to include at least an event that an operation for stopping the operation or an operation for reducing the heat generation amount of the heat source is executed by the user (fourth invention).

Here, during execution of the boiling detection process by the boiling detection unit, in a state where the detected value of the temperature of the cooking container has risen to a predetermined temperature or higher, an operation for stopping the operation of the heat source or reducing the heat generation amount of the heat source. The event that the operation for causing the user to perform is generated means that the operation of the heat source is stopped by the user recognizing the boiling state while the boiling state is not yet detected by the boiling detection unit. It can be considered that the operation for, or the operation for reducing the heat generation amount of the heat source is performed. Therefore, in the fourth aspect of the invention, the detection delay determination unit monitors whether or not the pre-detection event has occurred with the event as the pre-detection event.

Thereby, when the detection timing of the boiling state is behind the timing suitable for the user, it can be appropriately detected as the delayed state.

Moreover, in the said 1st-4th invention, when the said heat source is a combustion-type heat source which produces|generates a combustion flame, and the thermocouple which outputs the electromotive force according to this combustion flame is attached, The pre-detection event is a state in which a detected value of the temperature of the cooking container has risen to a predetermined temperature or higher during execution of boiling detection processing by the boiling detection unit, and an electromotive force of the thermocouple is lower than a predetermined value. It is preferable to include at least an event of being in a state (fifth invention).

Here, during the execution of the boiling detection process by the boiling detection unit, for example, in a state where the detected value of the temperature of the cooking container has risen above a predetermined temperature, an operation for stopping the operation of the heat source, or the amount of heat generated by the heat source. When an event occurs in which an operation for reducing (heat power) is performed by the user, the electromotive force of the heat source pair is stopped according to the stop of the operation of the heat source or the decrease in the heat generation amount (heat power) of the heat source. Becomes smaller. Further, during the execution of the boiling detection process by the boiling detection unit, for example, in a state where the detected value of the temperature of the cooking container rises above a predetermined temperature, the actual state of the liquid in the cooking container reaches the boiling state, When an event of liquid spillage occurs, the thermocouple is exposed to liquid, or the thermoelectric power in the vicinity of the thermocouple becomes weak, so that the electromotive force of the thermocouple becomes low. There are many.

Then, in the situation where the above-mentioned event occurs during the execution of the boiling detection process by the boiling detection unit, it can be considered that the detection timing of the boiling state by the boiling detection unit is later than the appropriate timing. Therefore, in the fourth aspect of the invention, the detection delay determination unit detects an event that the electromotive force of the thermocouple becomes lower than a predetermined value when the detected value of the temperature of the cooking container rises above a predetermined temperature. Whether or not the pre-detection event has occurred is monitored as the pre-detection event.

Accordingly, when the detection timing of the boiling state is delayed from the proper timing, it can be appropriately detected as the delayed state based on the electromotive force of the thermocouple.

In the first to fifth inventions, further, after the boiling state is detected by the boiling detection unit, the presence or absence of a predetermined post-detection event is monitored, and based on the presence or absence of the predetermined post-detection event, If the detection timing of the boiling state by the boiling detection unit is a premature detection determination unit that determines whether it is in an excessively early state, and the determination result of the detection premature determination unit is affirmative, the boiling detection process It is preferable to provide a premature detection response processing unit that executes a premature detection response processing regarding the change of the determination standard in (6th invention).

Here, according to various studies by the inventor of the present application, if the boiling state detection timing by the boiling detection unit is early, the user can easily recognize that the boiling state of the liquid in the cooking container is insufficient. Immediately after the boiling state is detected by the boiling detection unit, the user restarts the operation of the heat source or increases the amount of heat generated by the heat source. A peculiar event (event) tends to occur due to early detection of the boiling state.

Therefore, in the sixth aspect of the invention, the premature detection determination unit determines whether or not the boiling state detection timing by the boiling detection unit is in the premature state, based on the presence or absence of the post-detection event. .. Accordingly, when the boiling state detection timing is in the premature state, it is possible to appropriately detect that.

Then, the detection premature response processing unit, when the determination result of the detection premature determination unit is affirmative, that is, when it is detected that the detection timing of the boiling state is the premature state, the boiling detection A premature detection response process relating to the change of the determination criteria in the process is executed.

In this case, since the heating cooker performs the premature detection response process, it is possible to reduce the user's time and effort for reducing the premature state of the boiling state detection timing.

Therefore, according to the heating cooker of the sixth aspect of the present invention, it is possible to reduce the burden on the user regarding adjusting the detection timing of the boiling state so as to reduce the premature state of the detection timing, and improve the usability.

In the sixth aspect of the present invention, the boiling detection unit may be configured to be able to change the determination standard according to a predetermined operation of an operation unit included in the heating cooker. In this case, the detection premature response processing unit, the information for indicating the determination result of the detection premature determination unit, and the for changing the determination criteria to reduce the premature state of the detection timing of the boiling state The process of informing the user of at least one of the information indicating the operation method of the operation unit may be configured to be executed as the premature detection response process (seventh invention).

According to this, the user can easily operate the operation unit so as to reduce the premature state of the boiling state detection timing, and the usability of the heating cooker can be appropriately improved.

Further, in the sixth aspect of the present invention, the detection premature response processing unit, as the detection premature response processing, is processing for automatically changing the determination criterion so as to reduce the premature state of the detection timing of the boiling state. It can be configured to perform (eighth invention).

According to this, the premature state of the detection timing of the boiling state is automatically reduced by the process of the premature detection response processing unit, so that the burden on the user can be effectively reduced. It should be noted that it is possible to selectively perform the processing of the premature detection response processing section in the seventh invention and the processing of the premature detection response processing section in the eighth invention.

In the sixth to eighth inventions, when the boiling handling process is a process of stopping the operation of the heat source or reducing the heat generation amount of the heat source, the post-detection event is performed by the boiling detection unit. It is preferable to include at least an event that the user performs an operation of restarting the operation of the heat source or an operation of increasing the heat generation amount of the heat source within a predetermined time after detecting the boiling state (the ninth invention).

Here, the boiling response process, when the operation of the heat source is stopped, or is a process of lowering the heat generation amount of the heat source, immediately after the detection of the boiling state by the boiling detection unit, the operation of the heat source, The occurrence of the event that the user performs the operation of restarting or the operation of increasing the heat generation amount of the heat source means that the user recognizes that the boiling state of the liquid in the cooking container is insufficient, It can be considered that the operation of restarting the operation of the heat source or the operation of increasing the heat generation amount of the heat source is performed. Therefore, in the ninth aspect of the invention, the premature detection determination unit uses the event as a post-detection event and monitors the occurrence of the post-detection event.

Thereby, when the detection timing of the boiling state is earlier than the timing suitable for the user, this can be appropriately detected as the premature state.

Moreover, in the said 6th-9th invention, the said heat source is a combustion-type heat source which produces|generates a combustion flame, and the thermocouple which outputs the electromotive force according to this combustion flame is attached, and also the said. When the boiling correspondence process is a process of stopping the combustion operation of the heat source or reducing the heating power of the heat source, the post-detection event is within a predetermined time after the boiling state is detected by the boiling detection unit. Preferably includes at least an event that the electromotive force of the thermocouple becomes higher than a predetermined value (the tenth invention).

Here, the boiling response process, when the operation of the heat source is stopped, or is a process of lowering the heat generation amount of the heat source, immediately after the detection of the boiling state by the boiling detection unit, the operation of the heat source, When an event occurs in which the user performs an operation of restarting or an operation of increasing the heat generation amount of the heat source, depending on the restart of the operation of the heat source or the increase of the heat generation amount (thermal power) of the heat source. The electromotive force of the heat source pair increases.

Then, in the situation where the above-described event occurs immediately after the boiling state is detected by the boiling detection unit, it can be considered that the boiling state detection timing by the boiling detection unit is earlier than the appropriate timing. Therefore, in the tenth invention, the premature detection determination unit detects an event that the electromotive force of the thermocouple becomes higher than a predetermined value within a predetermined time after the boiling state is detected by the boiling detection unit. Whether or not the pre-detection event has occurred is monitored as an event.

Thereby, when the detection timing of the boiling state is earlier than the appropriate timing, it can be appropriately detected as the premature state based on the electromotive force of the thermocouple.

In another aspect of the heating cooker of the present invention, whether the liquid in the cooking container is in a boiling state in a state where the heat source and the cooking container in which the liquid is put are heated by the heat source. If a boiling detection unit that performs a boiling detection process that detects whether or not the liquid in the cooking container is detected by the boiling detection unit, a predetermined boiling response process is executed. A heating cooker including a boiling correspondence processing unit,
After the boiling state is detected by the boiling detection unit, the presence or absence of a predetermined post-detection event is monitored, and the boiling state detection timing by the boiling detection unit is based on the presence or absence of the predetermined post-detection event. A detection premature judgment unit that judges whether or not it is in a premature state,
When the determination result of the premature detection determination section is affirmative, a premature detection response processing section that executes a premature detection response processing relating to the change of the determination criterion in the boiling detection processing is provided. (Eleventh invention).

According to this, the same effect as the sixth aspect of the invention can be obtained. Note that the eleventh invention can further employ the same aspects as the seventh to tenth inventions.

Supplementally, as the boiling response process in the present invention, instead of the process of stopping the operation of the heat source, or the process of reducing the heat generation amount of the heat source, or in addition to these processes, the boiling detection unit May include a process of outputting notification information (for example, visual information or auditory information) indicating that the boiling state has been detected to the user.

Then, during the combustion operation of the burner 2, the fuel supply amount to the burner 2 is adjusted by controlling the thermal power adjustment valve 6, and by extension, the thermal power of the burner 2 is adjusted. Further, by controlling the on-off valve 5 to close, the fuel supply to the burner 2 is cut off, and the burner 2 is extinguished.

Although only one burner 2 is shown in FIG. 1, the heating cooker 1 may be provided with a plurality of burners capable of performing combustion operation separately.

The heating cooker 1 of the present embodiment further includes a display device 11 that displays various visual information, a sounding device 12 that outputs auditory information such as an alarm sound and a sound, and various operations relating to the operation of the heating cooker 1. The operation part 13 for the user to perform the operation, the thermocouple 14 as a flame detection sensor for detecting the combustion flame of the burner 2, and the temperature of the heating target such as the cooking container C heated by the burner 2 can be detected. The temperature detector 15 and the control device 20 having the function of controlling the operation of the heating cooker 1 are provided.

The display 11 is composed of, for example, a liquid crystal display, an LED display, an organic EL display, etc., and the sounder 12 is composed of, for example, a speaker, a buzzer, etc. The thermocouple 14 is attached in the vicinity of the burner 2 so as to output an electromotive force according to the presence or absence of the combustion flame of the burner 2 and its strength. The temperature detector 15 has a built-in temperature sensor such as a thermistor, and a heating object such as a cooking container C is placed on a Gotoku (not shown) installed around the burner 2, The burner 2 is installed at the center of the burner 2 so as to contact the bottom surface of the heating object and transfer heat from the heating object.

In the present embodiment, the operation unit 13 is a burner operation unit 13a for performing an ignition operation, a fire extinguishing operation, and a heat power adjustment operation of the burner 2, a water heating switch 13b for performing an automatic water heating operation in the burner 2, and an automatic water heating. It includes boiling detection adjustment switches 13c1 and 13c2 for performing an adjustment operation regarding the detection timing of the boiling state during operation.

The burner operating unit 13a is configured to perform a pushing operation for igniting or extinguishing the burner 2 and a rotating operation for adjusting heat power, for example. However, for example, the operation unit for igniting or extinguishing the burner 2 and the operation unit for adjusting the heat power may be different operation units.

More specifically, the automatic boiling operation is performed by the control device 20 when the liquid such as water put in the cooking container C (kettle, pot, etc.) as the heating target of the burner 2 is in a boiling state. It is detected that the control device 20 automatically extinguishes the burner 2 (or automatically reduces the heating power of the burner 2 to a predetermined small heating power) in response to the detection, and the liquid is in a boiling state. The operation is such that the notification information indicating is displayed on the display 11 or output from the sounder 12.

The boiling water switch 13b is an operation switch for instructing the control device 20 to execute the automatic boiling water operation, and the switch 13c1 of the boiling detection adjustment switches 13c1 and 13c2 determines the boiling state detection timing from the current detection timing. The operation switch for speeding up the operation, the switch 13c2 is an operation switch for delaying the detection timing of the boiling state from the current detection timing.

The operation unit 13 may include various operation units such as the burner operation unit 13a, the water heating switch 13b, the boiling detection adjustment switches 13c1 and 13c2, and the operation unit related to the automatic cooking operation. Further, the boiling detection adjustment switches 13c1 and 13c2 do not need to be dedicated switches for adjusting the detection timing of the boiling state, and switches that also have other functions (for example, setting of temperature or time relating to automatic cooking operation) May be

The control device 20 is composed of, for example, an electronic circuit unit including a microcomputer, a memory, an interface circuit, etc., and receives an operation signal of the operation section 13 and various sensors (the thermoelectric generator) provided in the heating cooker 1. The detection signal (including the pair 14 and the temperature detector 15) is input.

Then, the control device 20 has a function of controlling the combustion operation of the burner 2 and a display of the display 11 and a sound generator 12 as functions realized by both or one of the installed hardware configuration and/or program (software configuration). And the function of controlling the operation of. Further, as shown in FIG. 1, the control device 20 includes a boiling detection unit 21 that executes a boiling detection process that detects whether the liquid in the cooking container C heated by the burner 2 is in a boiling state, and the boiling detection unit 21. A state in which the detection timing of the boiling state by the detection unit 21 can be considered to be later than an appropriate timing (hereinafter, referred to as a detection delay state) and a state that can be considered to be earlier than an appropriate timing (hereinafter, referred to as an excessive detection state). And a detection delay/premature determination unit 22 for determining whether or not the detection timing of the boiling state is the detection delay state or the pre-detection state. The detection delay/premature response processing unit 23 that executes the response processing relating to the change, and the boiling response processing unit 24 that executes the predetermined boiling response processing in response to the detection of the boiling state by the boiling detection unit 21.

In the present embodiment, the boiling detection unit 21 sequentially acquires the detected value of the temperature of the cooking container C detected by the temperature detector 15 while the cooking container C is being heated by the burner 2, and detects the detected value of the temperature. It is determined whether or not the temperature of the liquid in the cooking container C is in the boiling state, based on a predetermined determination criterion regarding the change mode.

For example, the boiling detection unit 21 detects the temperature of the cooking container C when the detected value of the temperature of the cooking container C exceeds a predetermined value by a timer that measures the time required to rise. When the state where the value is kept substantially constant at the predetermined temperature or higher continues for the predetermined time or longer, it is determined that the temperature of the liquid in the cooking container C is in the boiling state. In addition to this, as a more specific method for detecting the boiling state by the boiling detection unit 21 using the detected value of the temperature of the cooking container C, for example, the method found in Patent Document 1 or 3 can be adopted. ..

The detection delay/premature determination unit 22 performs a predetermined pre-detection event related to the combustion operation of the burner 2 during the boiling detection process performed by the boiling detection unit 21 (during the boiling detection process before the boiling state is detected). Is detected and whether or not the detection timing of the boiling state by the boiling detection unit 21 is the detection delay state is determined based on the presence or absence of the pre-detection event.

The pre-detection event is an event that can occur before the boiling state is detected due to the late detection timing of the boiling state. In the present embodiment, the pre-detection event is, for example, an event in which the combustion operation of the burner 2 is stopped by the user's fire extinguishing operation when the detected value of the temperature of the cooking container C has risen to a temperature equal to or higher than a predetermined temperature. And an event that the electromotive force output from the thermocouple 14 is in a low level state lower than a predetermined value when the detected value of the temperature of the cooking container C has risen to a predetermined temperature or higher.

Further, the detection delay/premature determination unit 22 monitors whether or not a predetermined post-detection event regarding the combustion operation of the burner 2 occurs after the boiling state is detected by the boiling detection unit 21, and the occurrence of the post-detection event occurs. Based on the presence/absence of the above condition, it is determined whether or not the detection timing of the boiling state by the boiling detection unit 21 is the pre-detection state.

The post-detection event is an event that can occur after the boiling state is detected due to the early detection of the boiling state. In the present embodiment, the post-detection event is, for example, an event in which the user performs a re-ignition operation on the burner 2 within a predetermined time after the boiling state is detected.

In the present embodiment, the detection delay/premature response processing unit 23 reduces the detection delay state when it is determined that the boiling state detection timing is the detection delay state (boiling state detection timing. So that it approaches the appropriate timing), the process of automatically correcting the parameters used in the judgment criteria for detecting the boiling state is executed, or the operation method for reducing the detection delay state is provided to the user. Then, the process of informing is performed.

Further, when it is determined that the detection timing of the boiling state is the premature detection state, the detection delay/premature response processing unit 23 reduces the premature detection state in the present embodiment. To make the detection timing closer to the proper timing), execute the process to automatically correct the parameters used in the judgment criteria for detecting the boiling state, or use the operation method to reduce the pre-detection state. A process of notifying the user is executed.

In the present embodiment, the boiling response processing unit 24 automatically controls the burner 2 to extinguish the fire by controlling the closing of the on-off valve 5 according to the detection of the boiling state by the boiling detection unit 21, and the boiling state is detected. Displaying the notification information indicating that it has been performed on the display device 11 or outputting it from the sound generator 12 is executed as a boiling correspondence process.

Next, more specific control processing of the control device 20 of the present embodiment will be described with reference to the flow charts of FIGS. 2 and 3.

When the user starts the combustion operation of the burner 2 by the ignition operation of the burner operation unit 13a and then turns on the boiling water switch 13b so that the liquid in the cooking container C heated by the burner 2 is boiled by the automatic boiling operation, the control is performed. The device 20 executes the control process shown in the flowcharts of FIGS. 2 and 3.

In STEP1, the control device 20 starts water heating control. In this case, the control device 20 starts the process of the boiling detection unit 21 (boiling detection process). In the processing of the boiling detection unit 21, the control device 20 sequentially acquires the detected value of the temperature of the cooking container C by the temperature detector 15 and determines whether the liquid in the cooking container C is in the boiling state as described above. To detect.

Next, in STEP 2, the control device 20 determines whether or not the boiling state is detected by the processing of the boiling detection unit 21. If the determination result is negative, the control device 20 then performs the process of the detection delay/premature determination unit 22 for determining whether the detection delay state of the boiling state detection timing has occurred. The processes of STEPs 3 to 6 are executed.

Specifically, the control device 20 determines whether or not the combustion operation of the burner 2 is stopped in STEP3 subsequent to STEP2 (in other words, whether or not the burner 2 is extinguished by the valve closing control of the opening/closing valve 5). To judge. Then, if the determination result in STEP 3 is affirmative, the control device 20 further determines in STEP 5 that the detected value of the temperature of the cooking container C (current detected temperature value) by the temperature detector 15 is equal to or higher than the predetermined temperature. It is determined whether (for example, 90° C. or higher).

When the determination result of STEP3 is negative, the control device 20 further determines in STEP4 whether or not the electromotive force output from the thermocouple 14 is in a low level state lower than a predetermined value. In this case, in the present embodiment, the control device 20 determines that the electromotive force is in the low level state when the electromotive force output from the thermocouple 14 is continuously lower than the predetermined value for a predetermined time or more, for example. to decide. Alternatively, for example, the control device 20 determines that the electromotive force is in the low level state when the average value of the electromotive force output from the thermocouple 14 per predetermined time width is lower than the predetermined value.

Then, when the determination result of STEP4 is negative, the control device 20 repeats the processing from STEP2 until the determination result of STEP2 becomes affirmative. If the determination result of STEP4 is affirmative, the control device 20 further executes the determination process of STEP5.

Here, before the boiling state of the liquid in the cooking container C is detected by the boiling detection unit 21 (before the determination result of STEP 2 becomes affirmative), the user determines from the state of the liquid in the cooking container C or the like. , An event in which the user determines that the liquid has reached a desired boiling state, and then the user operates the burner 2 to extinguish the burner 2 with the burner operation unit 13a (hereinafter referred to as a first pre-detection event), or In some cases, an event (hereinafter, referred to as a second pre-detection event) that an operation of reducing the heating power of the burner 2 is performed by the burner operation unit 13a may occur.

Further, before the boiling state of the liquid in the cooking container C is detected by the boiling detection unit 21 (before the determination result of STEP 2 becomes positive), the actual state of the liquid in the cooking container C becomes the boiling state. As a result, the liquid spills from the cooking container C, and the liquid is splashed on the thermocouple 14, or the combustion flame near the thermocouple 14 is weakened. An event (hereinafter, referred to as a third pre-detection event) that the electromotive force output from the device decreases to a low level state may occur.

These first to third pre-detection events are events that can occur when the temperature of the liquid in the cooking container C has risen sufficiently. Therefore, in other words, in the first pre-detection event, the combustion operation of the burner 2 is performed by the user while the detected value of the temperature of the cooking container C has risen to a certain temperature or higher before the boiling state is detected. It can be said that the event is stopped by the fire extinguishing operation. Therefore, when the first pre-detection event occurs, the determination results of STEP3 and STEP5 are affirmative. Then, in the situation in which the first pre-detection event occurs, the detection timing of the boiling state by the boiling detection unit 21 can be regarded as the detection delay state.

In addition, each of the second pre-detection event and the third pre-detection event is, in other words, a state in which the detected value of the temperature of the cooking container C has risen to a certain temperature or higher before the boiling state is detected. The event is that the electromotive force output from the thermocouple 14 becomes a low level state due to the user's operation of reducing the heat power of the burner 2 or the spilling of the liquid in the cooking container C. Therefore, when the second pre-detection event or the third pre-detection event occurs, the determination result of STEP3 becomes negative and the determination results of STEP4 and STEP5 become positive. Then, in a situation where the second pre-detection event or the third pre-detection event occurs, the detection timing of the boiling state by the boiling detection unit 21 can be regarded as the detection delay state.

Therefore, the control device 20 determines whether the determination results of STEP3 and STEP5 become positive before the determination result of STEP2 becomes affirmative, or when the determination result of STEP3 becomes negative and the determination results of STEP4 and STEP5 become negative. If the determination result is affirmative, in STEP 6, it is determined that the detection timing of the boiling state by the boiling detection unit 21 is the detection delay state, and in STEP 7, the boiling water control is ended.

In STEP 7, the control device 20 ends the process of the boiling detection unit 21. Further, when the burner 2 is in the combustion operation (when the determination results of STEPs 4 and 5 are positive due to the occurrence of the second pre-detection event or the third pre-detection event), the control device 20 The burner 2 is extinguished by controlling the on-off valve 5 to close. In STEP 7, the notification information indicating that the water heating control is ended (or that the automatic water heating operation is ended) may be displayed on the display device 11 or output from the sounder 12.

Supplementally, the determination result of STEP3 and STEP5 becomes positive before the determination result of STEP2 becomes positive, or the determination result of STEP3 becomes negative and the determination result of STEP4 and STEP5 becomes positive. The fact that the control device 20 recognizes that the state has become equal to is equivalent to determining that the detection timing of the boiling state is the detection delay state, and therefore the direct execution of the process of STEP 6 can be omitted.

Next, the control device 20 executes the processing of STEPs 8 to 11 as the processing of the detection delay/premature response processing unit 23 for dealing with the detection delay state. Specifically, in STEP 8 following STEP 7, the control device 20 determines whether or not the current number of occurrences of detection delay stored and held in a memory (not shown) exceeds a predetermined number (for example, 4 times). The number of times of occurrence of the detection delay is the number of times that the detection timing of the boiling state is determined to be the detection delay state during the execution of the past boiling control before the execution of the current boiling control, and the number of times when the heating cooker 1 is new. The default value is zero, and it is reset (initialized) to zero in STEP 10 described later each time the predetermined number of times is exceeded.

If the determination result in STEP8 is negative (the number of detection delay occurrences is equal to or less than the predetermined number of times), the control device 20 sets the value of the number of detection delay occurrences stored in the memory to "1" in STEP11. Update to the increased value. Further, in STEP 12, the control device 20 executes the process of correcting the detection timing of the boiling state by the boiling detection unit 21 so as to reduce the detection delay state of the boiling state, and ends the process of the flowchart of FIG. 2.

In this case, in STEP 12, the control device 20 corrects the detection timing by correcting a parameter such as a threshold value (hereinafter referred to as a boiling detection parameter) used in the determination standard that defines the detection timing of the boiling state. For example, the boiling detection unit 21 is configured to detect the boiling state when the measured value of the timer for measuring the time required for the detected temperature of the cooking container C to rise by a predetermined temperature exceeds the predetermined value. If so, the control device 20 updates the predetermined value (threshold value) to be compared with the measured value of the timer to a value smaller than the current value by a predetermined amount. As a result, the predetermined value as the boiling detection parameter is automatically corrected so that the detection delay state of the boiling state detection timing is reduced (so that the boiling state detection timing is earlier than the current timing). It

Further, for example, the boiling detection unit 21 is configured to detect the boiling state when the state where the detected value of the temperature of the cooking container C is kept substantially constant at a predetermined temperature or higher continues for a predetermined time or longer. If so, the control device 20 makes the predetermined time (threshold value) related to the duration of the state in which the detected value of the temperature of the cooking container C is kept substantially constant above the predetermined temperature by a predetermined amount smaller than the current value. Update to the value. Thereby, the predetermined time as the boiling detection parameter is automatically corrected so that the detection delay state of the detection timing of the boiling state is reduced (so that the detection timing of the boiling state is earlier than the current timing). It

The boiling detection parameter for correcting the detection timing of the boiling state can be appropriately selected according to the method of detecting the boiling state by the boiling detection unit 21. Further, in STEP 12, the notification information indicating that the process for correcting the detection timing of the boiling state has been executed may be displayed on the display device 11 or may be output from the sound generator 12. Further, only when the user is inquired of whether or not the detection timing of the boiling state can be automatically corrected through the display device 11 or the sound generator 12 and the user performs a predetermined operation to permit the correction, You may perform the process of STEP12.

When the determination result of STEP8 is affirmative (the number of detection delay occurrences>the predetermined number of times), the control device 20 changes the detection timing of the boiling state in STEP9 so as to reduce the detection delay state. The notification information (guidance information) that allows the user to recognize the operating method for displaying the information is displayed on the display 11 or output from the sounder 12. Further, the control device 20 resets (initializes) the number of detection delay occurrences to zero in STEP 10 (provided that the user performs a required operation according to the notification in STEP 9), and The process shown in the flowchart is finished.

In STEP 9 described above, the control device 20 displays, for example, notification information indicating that the push operation of the switch 13c1 of the boiling detection adjustment switches 13c1 and 13c2 should be performed in the combustion operation stop state of the burner 2 on the display device. 11 or output from the sound generator 12. Thereby, the user does not need to check the instruction manual of the heating cooker 1 or contact the support center, and an operation method for reducing the detection delay state of the detection timing of the boiling state. Can be easily recognized and executed.

When such an operation is performed by the user, the control device 20 corrects the boiling detection parameter as in STEP12. However, in this case, the correction amount of the boiling detection parameter according to the user's operation (operation of the boiling detection adjustment switch 13c1) is set to a larger correction amount than the correction amount in STEP12. As a result, even when the amount of deviation between the boiling state detection timing and the proper timing is relatively large, the corrected detection timing easily approaches the proper timing. It should be noted that the user does not perform the above-described operation according to the notification of STEP 9 and the power of the cooking device 1 is turned off, or when a predetermined time elapses, or when the burner 2 is reignited. If the above is performed, the process of resetting the number of detection delay occurrences in STEP 10 is omitted.

In the present embodiment, as described above, if the determination results of STEP3 and STEP5 become affirmative before the determination result of STEP2 becomes affirmative, or the determination result of STEP3 becomes negative, and STEP4 and When the determination result of STEP 5 is affirmative, it is determined that the detection timing of the boiling state is the detection delay state, and the process relating to the correction of the detection timing (the automatic correction process of the boiling detection parameter or the boiling state is performed). Notification processing of the operating method for correcting the detection timing of) is executed.

On the other hand, in a state where the heating of the cooking container C by the burner 2 has not progressed so much, the user extinguishes the burner 2 in order to stop or delay boiling of the liquid in the cooking container C, or In some cases, the operation of reducing the heating power of the burner 2 is performed. In this case, although the determination result of STEP3 or STEP4 is affirmative, since the detected value of the temperature of the cooking container C is low, the determination result of STEP5 is negative. Then, in this case, the control device 20 does not determine that the detection timing of the boiling state is the detection delay state, and in STEP 13, the boiling water control is ended in the same manner as in STEP 7, and the processing shown in the flowchart of FIG. 2 is performed. finish.

If the boiling state is detected by the process of the boiling detection unit 21 without the determination result of STEP3 or STEP4 becoming affirmative, the determination result of STEP2 becomes affirmative. This situation is a situation in which the boiling state is detected at a proper timing for the user without the liquid in the cooking container C spilling over. Then, in this case, the control device 20 ends the boiling water control in STEP 14 without determining that the detection timing of the boiling state is the detection delay state.

In STEP 14, the control device 20 finishes the process of the boiling detection unit 21 (boiling detection process) and executes the boiling handling process by the boiling handling unit 24. In this boiling response processing, the control device 20 controls the closing valve 5 to close the valve to extinguish the burner 2. Further, the control device 20 causes the display device 11 to display notification information indicating that the boiling state has been detected, or causes the sounding device 12 to output the notification information.

Subsequently, the control device 20 executes the process shown in the flowchart of FIG. In this case, the control device 20 executes the processes of STEPs 15 to 18 as the process of the detection delay/premature judgment unit 22 for judging whether or not the detection premature state of the boiling state detection timing has occurred.

Specifically, in STEP 15, control device 20 activates a timer for measuring the elapsed time after the end of the water heating control in STEP 14. Next, the control device 20 determines in STEP 16 whether or not the measured value of the timer exceeds a predetermined time (for example, 10 seconds), and in STEP 17, the re-ignition operation of the burner 2 is executed by the burner operation unit 13a. The determination as to whether or not the determination has been made is repeated until the determination result at any one of STEPs 16 and 17 becomes affirmative.

When the re-ignition operation of the burner 2 is performed before the determination result of STEP16 becomes affirmative (before the timer value exceeds the predetermined time), the determination result of STEP17 becomes affirmative. In this situation, an event (hereinafter, referred to as a post-detection event) in which the user performs the re-ignition operation of the burner 2 immediately after the boiling water control is ended in response to the detection of the boiling state is generated. The post-detection event is due to the user recognizing that the cooking container C is insufficiently heated because the boiling state detection timing of the boiling detection unit 21 is earlier than the proper timing desired by the user. Can occur.

Therefore, when the determination result of STEP17 becomes affirmative before the determination result of STEP16 becomes affirmative, the control device 20 determines in STEP18 that the boiling state detection timing by the boiling detection unit 21 is too early. It is determined to be in the state. Note that the control device 20 recognizes that the determination result of STEP17 has become affirmative before the determination result of STEP16 becomes affirmative, that is, it is determined that the detection timing of the boiling state is the pre-detection state. Since it is equivalent to that, the direct execution of the process of STEP 18 can be omitted.

Next, the control device 20 executes the processes of STEPs 19 to 23 as the process of the detection delay/premature response processing unit 23 for handling the premature detection state. Specifically, in STEP 19, the control device 20 determines whether or not the current number of premature detection occurrences stored and held in a memory (not shown) exceeds a predetermined number (for example, 4 times). The number of occurrences of premature detection is the number of times that the detection timing of the boiling state is determined to be premature detection immediately after the end of the past boiling control before execution of the current boiling control, The default value at the time of new product is zero, and it is reset (initialized) to zero at STEP 21 described later each time the predetermined number of times is exceeded.

If the determination result in STEP 19 is negative (the number of premature detection occurrences≦a predetermined number of times), the control device 20 sets the value of the number of premature detection occurrences stored in the memory to “1” in STEP 22. Update to the value increased by ". Further, in STEP 23, the control device 20 executes a process of correcting the detection timing of the boiling state by the boiling detection unit 21 so as to reduce the pre-detection state of the boiling state, and ends the process of the flowchart of FIG. 3. ..

In this case, in STEP23, the control device 20 corrects the detection timing by modifying the same parameter as the boiling detection parameter that is modified in STEP12 to reduce the detection delay state. For example, the boiling detection unit 21 is configured to detect the boiling state when the measured value of the timer that measures the time required for the detected temperature of the cooking container C to rise by the predetermined temperature exceeds the predetermined value. If so, the control device 20 updates the predetermined value (threshold value) to be compared with the measured value of the timer to a value that is larger than the current value by a predetermined amount. As a result, the predetermined value as the boiling detection parameter is automatically set so that the pre-detection state of the detection timing of the boiling state is reduced (so that the detection timing of the boiling state becomes later than the current timing). Will be fixed.

Further, for example, the boiling detection unit 21 is configured to detect the boiling state when the state where the detected value of the temperature of the cooking container C is kept substantially constant at a predetermined temperature or higher continues for a predetermined time or longer. If so, the control device 20 increases the predetermined time (threshold value) related to the duration of the state in which the detected value of the temperature of the cooking container C is kept substantially constant above the predetermined temperature by a predetermined amount larger than the current value. Update to the value. As a result, in order to reduce the premature detection of the boiling state detection timing (so that the boiling state detection timing is later than the current timing), the predetermined time as the boiling detection parameter is automatically set. Will be fixed.

In STEP 23, the notification information indicating that the processing for correcting the boiling state detection timing has been executed may be displayed on the display device 11 or may be output from the sound generator 12. Further, only when the user is inquired of whether or not the detection timing of the boiling state can be automatically corrected through the display device 11 or the sound generator 12 and the user performs a predetermined operation to permit the correction, You may perform the process of STEP23.

If the determination result of STEP 19 is affirmative (the number of occurrences of premature detection>the predetermined number of times), the control device 20 reduces the detection timing of the boiling state to reduce the premature detection state in STEP 20. Notification information (guidance information) that allows the user to recognize the operation method for changing is displayed on the display device 11 or output from the sound generator 12. Further, the control device 20 resets (initializes) the number of premature detection occurrences to zero in STEP 21 (provided that the user performs a required operation according to the notification in STEP 20), and The process shown in the flowchart of FIG.

In STEP 20, the control device 20 displays, for example, notification information indicating that the push operation of the switch 13c2 of the boiling detection adjustment switches 13c1 and 13c2 should be performed in a state where the combustion operation of the burner 2 is stopped. It is displayed on the instrument 11 or output from the sounder 12. Thereby, the user does not need to check the instruction manual of the heating cooker 1 or contact the support center, and the operation for reducing the premature detection state of the detection timing of the boiling state can be performed. The method can be easily recognized and implemented.

When such an operation is performed by the user, the control device 20 corrects the boiling detection parameter as in STEP23. However, in this case, the correction amount of the boiling detection parameter according to the user's operation (operation of the boiling detection adjustment switch 13c2) is set to a correction amount larger than the correction amount in STEP23. As a result, even when the amount of deviation between the boiling state detection timing and the proper timing is relatively large, the corrected detection timing easily approaches the proper timing. It should be noted that the user does not perform the above-described operation according to the notification of STEP 20 and the power of the cooking device 1 is turned off, or a predetermined time has elapsed, or the burner 2 is re-ignited. If the above is performed, the process of resetting the number of premature detection occurrences in STEP 21 is omitted.

In the present embodiment, as described above, when the re-ignition operation of the burner 2 is performed (before the determination result of STEP16 becomes affirmative) immediately after the completion of the water heating control according to the detection of the boiling state (determination of STEP17). If the result is affirmative), it is determined that the detection timing of the boiling state is in the pre-detection state, the process related to the correction of the detection timing (automatic correction process of parameters for boiling detection, or of the boiling state Notification processing of the operating method for correcting the detection timing) is executed.

According to the embodiment described above, when the detection timing of the boiling state by the boiling detection unit 21 is the detection delay state or the detection premature state, the boiling state is changed so as to reduce the detection delay state or the detection premature state. The adjustment of the detection timing is automatically executed, or the notification information indicating the operation method for the adjustment is presented to the user, which reduces the user's burden on the adjustment and improves the usability of the heating cooker. Can be increased.

The present invention is not limited to the embodiment described above, and other embodiments can be adopted. Some other embodiments will be exemplified below.

In the embodiment, in order to determine whether or not the detection timing of the boiling state is the pre-detection state, immediately after the boiling water control is completed in response to the detection of the boiling state (the determination result of STEP 16 becomes affirmative). Before), it was determined whether or not the re-ignition operation of the burner 2 was performed. However, instead of determining whether or not the re-ignition operation of the burner 2 is performed, for example, as shown in the flowchart of FIG. 4, before the determination result of STEP 16 becomes positive, the electromotive force of the thermocouple 14 is set to a predetermined value. It may be determined in STEP 27 whether or not the temperature has risen to the above high level state, and if the determination result is affirmative, it may be determined that the detection timing of the boiling state is the pre-detection state. Alternatively, if the determination result of either STEP 17 or 27 becomes affirmative before the determination result of STEP 16 becomes affirmative, it is determined that the detection timing of the boiling state is the pre-detection state. May be.

Further, in the above-described embodiment, every time the detection timing of the boiling state is determined to be the detection delay state, the correction processing of the detection timing is executed in STEP 12, or the notification information on the operation method for changing the detection timing is transmitted in STEP 9. Now output to the user. Similarly, each time the detection timing of the boiling state is determined to be the pre-detection state, the correction processing of the detection timing is executed in STEP23, or the notification information regarding the change operation method of the detection timing is sent to the user in STEP20. I tried to output it.

However, for example, as shown in the flowchart of FIG. 5A, until the number of times of occurrence of the detection delay reaches a predetermined number, the correction processing of the detection timing of the boiling state and the notification of the operation method for changing the detection timing are not executed, and the detection delay occurs. When the number of times exceeds the predetermined number, the correction processing of the boiling state detection timing (the processing of STEP 12) may be executed. Similarly, as shown in the flowchart of FIG. 5B, for example, until the number of occurrences of premature detection reaches a predetermined number, correction processing of the detection timing and notification regarding the operation method for changing the detection timing are not executed, and the premature detection occurs. When the number of times exceeds a predetermined number, the correction processing of the boiling state detection timing (processing of STEP23) may be executed. Note that, in FIG. 5A, instead of the processing of STEP 12, the processing of STEP 9 (notification regarding the operation method for changing the detection timing) may be executed. Similarly, in FIG. 5B, instead of the processing of STEP23, the processing of STEP20 (notification regarding the operation method for changing the detection timing) may be timed.

Further, in the above-described embodiment, in order to determine whether or not the detection timing of the boiling state is the detection delay state, before the boiling state is detected by the boiling detection unit 21, either one of STEPs 3 and 4 is determined. Although it is determined whether or not the result becomes affirmative, the determination process of either STEP 3 or STEP 4 may be omitted.

Further, in the above-described embodiment, the burner 2 is automatically extinguished (the on-off valve 5 is closed and controlled) as the boiling response process when the boiling state is detected. However, instead of extinguishing the burner 2, The heat adjustment valve 6 may be controlled so as to reduce the heat of the burner 2. In this case, the determination as to whether or not the detection timing of the boiling state is the detection delay state can be made in the same manner as in the above embodiment. Further, the determination as to whether or not the detection timing of the boiling state is the pre-detection state can be made by, for example, the process shown in the flowchart of FIG.

Further, as the boiling response processing when the boiling state is detected, for example, while the thermal power of the burner 2 (heat generation amount of the heat source) is maintained, the notification information indicating that the boiling state is detected is displayed on the display unit 11. Alternatively, it may be output from the sound generator 12. In this case, the determination as to whether or not the detection timing of the boiling state is the detection delay state can be made in the same manner as in the above embodiment. Further, whether or not the detection timing of the boiling state is the pre-detection state is determined by, for example, the boiling state immediately after the boiling water control is completed according to the detection of the boiling state (before the determination result of STEP16 becomes affirmative). The determination may be made based on whether or not the user has performed a predetermined operation for stopping the output of the notification information indicating that the detection has been performed.

Moreover, in the said embodiment, although the notification information regarding the change operation method of the detection timing of a boiling state was output to a user in STEP9, 20, instead of the said notification information, or in addition to the said notification information. For example, the notification information indicating that the detection timing of the boiling state is the detection delay state or the premature detection state may be output to the user. Thereby, the user explicitly recognizes that the detection timing of the boiling state is the detection delay state or the detection premature state, and then performs the operation for reducing the detection delay state or the detection premature state. We can recognize the relevance of things.

Further, in the above embodiment, the detection of the boiling state in the automatic boiling water operation is described, but the present invention can be applied to the case where the liquid in the cooking container C is boiled, for example, in the process of the automatic cooking operation. It is possible.

Further, in the above-mentioned embodiment, the gas cooker is exemplified as the heating cooker, but the present invention is also applied to a cooker having an IH heater or an electric heater as a heat source, or a heating cooker other than the gas cooker, such as a rice cooker. You can
