Description

  In the present invention, whether the object to be heated is placed on the placement part for placing the object to be heated to be heated by the heating means or not placed is not placed. A heating state of the heating means is started based on a heating start command by the heating state detecting means, a temperature detecting means for detecting the temperature of the object to be heated placed on the mounting portion, and a heating instruction means. Heating start processing, heating stop processing for stopping the heating operation of the heating means based on a heating stop command by the heating command means, detection information of the placement state detection means, detection information of the temperature detection means, and The present invention also relates to a heating cooker provided with heating control means for performing cooking heating processing for controlling the heating operation of the heating means based on preset heating control information.

  Such a heating cooker can be used as the heating process for cooking, for example, even if a heating start command is commanded by the heating command means when the non-placed state is detected by the placement state detection means, A process for checking the heating operation, a process for reducing the heating amount when the non-placed state is detected by the placing state detecting means when the heating means is performing the heating operation, or the like, Further, based on the detection information of the temperature detecting means, a process for adjusting the heating amount of the heating means so as to maintain the temperature of the heated object at the set temperature during cooking of the heated object is performed. Based on the detection information of the placement state detection means and the temperature detection means, it is possible to perform appropriate cooking on the object to be heated.

  And in such a heating cooker, an abnormal state such as the placement state detecting means sticking and failing due to boiled juice falling from the object to be heated may occur, and such an abnormal state is As a configuration for detection, there has conventionally been a configuration configured as follows.

  That is, the mounting state duration time in which the previous mounting state is continuously detected by the previous mounting state detection means is integrated, and the integrated value of the mounting state duration reaches the set time for abnormality determination. Then, the guide information that prompts the user to raise the object to be heated is notified from the placement unit, and there is a state where the previous placement state is detected by the previous placement state detection means even if a set time has elapsed since the notification of the guidance information. When the operation is continued, there is an abnormality countermeasure process in which the heating operation is checked regardless of the heating start command by the heating command means (see, for example, Patent Document 1). Incidentally, the set time for abnormality determination is set to a time when it is considered that the state in which the object to be heated is continuously placed on the placement portion is hardly possible, for example, about 96 hours. ing.

  By the way, in this kind of heating cooker, in the case where a dry cell is used as a power source, in order to suppress power consumption as much as possible, when heating operation of the heating unit is performed, power supply to the heating control unit is started, and the heating unit When the heating operation is stopped, the power supply to the heating control means is cut off, but there is also a usage form in which the object to be heated is lifted from the mounting portion after the heating operation of the heating means is stopped. When the heating state of the heating unit is stopped, if the mounting state is detected by the mounting state detection unit, power supply to the heating control unit is continued until the non-mounting state is detected. There is what I did.

JP 2006-97976 A

  The conventional configuration has the following disadvantages because it is configured to perform abnormality countermeasure processing when the above-described stationary state continuation time reaches the abnormality determination set time.

  That is, as a usage pattern in this type of cooking device, after the user places an object to be heated on the placement unit, the heating means starts heating operation to start cooking, and this cooking is being performed. After the cooking is finished and the heating operation of the heating means is stopped without performing the mounting state changing work such as lifting the heated object from the mounting part or moving to another place, the mounting state of the heated object Change operation may be performed.

  In the above-described conventional configuration, when the placement state detection unit operates normally in such a usage pattern, the placement state detection unit is performed by performing the above-described placement state change operation by the user. Since the non-mounting state is detected, the above-described mounting state duration time is reset. However, if the mounting state detecting unit is stuck and malfunctions, the mounting state detection is performed. Since the means continues to be placed, even if the user stops the heating operation of the heating means and then performs a placement state change operation for the object to be heated, the above-described placement state duration time is continuously accumulated. Therefore, there is a disadvantage that the abnormal state of the mounting state detection unit cannot be detected early after the heating operation of the heating unit is stopped.

  It is an object of the present invention to effectively detect the abnormal state of the mounting state detection means early after stopping the heating operation of the heating means by effectively using the temperature detection means provided for cooking. The point is to provide a cooking device.

The heating cooker according to the present invention is in a mounting state in which the object to be heated is mounted on the mounting portion on which the object to be heated to be heated by the heating means is mounted or is not mounted A mounting state detecting means for detecting whether or not the state;
Temperature detecting means for detecting the temperature of the object to be heated placed on the placing portion;
A heating start process for starting the heating operation of the heating means based on a heating start command by the heating command means, a heating stop process for stopping the heating operation of the heating means based on a heating stop command by the heating command means, A heating control means for performing a cooking heating process for controlling a heating operation of the heating means based on detection information of the placement state detection means, detection information of the temperature detection means, and preset heating control information; Is provided,
The first characteristic configuration is that when the heating control unit switches from a heating operation state in which the heating unit is heated to a heating stop state in which the heating operation is stopped, the installation state detection unit performs the installation described above. When the state is detected, it is determined whether or not a temperature suddenly falling state occurs in which the temperature of the object to be heated placed on the placement unit suddenly falls based on the detection information of the temperature detecting unit. A temperature change determination process for determining is executed, and an abnormality occurrence corresponding process is executed when the occurrence of the sudden temperature drop state is determined in the temperature change determination process.

  According to the first characteristic configuration, when the heating control unit switches from a heating operation state in which the heating unit is heated to a heating stop state in which the heating operation is stopped, the heating state is described in the mounting state detection unit. If a placement state is detected, it is determined whether or not a temperature sudden drop state occurs in which the temperature of the object to be heated placed on the placement unit suddenly falls based on the detection information of the temperature detection means. It is determined.

  In other words, when switching from the heating operation state in which the heating means is heated to the heating stop state in which the heating operation is stopped, the object to be heated is heated by the heating means and is brought into a high temperature by natural heat dissipation. Although the temperature gradually decreases, at that time, the temperature detecting means detects the temperature of the object to be heated that is still mounted on the mounting portion, and therefore the fluctuation of the detected value becomes gradual.

  However, if the object to be heated is lifted and removed from the mounting section after the heating means is switched to the heating stop state, the temperature detection means detects the temperature of the air, not the object to be heated, so the detected value Therefore, the object to be heated is lifted and removed from the mounting portion when it is determined that a temperature suddenly falling state in which the temperature suddenly drops is generated based on the detection information of the temperature detecting means. Can be distinguished.

  If the occurrence of the temperature sudden drop state is detected in spite of the fact that the previous placement state is detected by the previous placement state detection means, the previous placement state detection means has failed or is placed. It is assumed that an abnormal state such as being stuck in a state where the temperature is detected, so that the heating control means responds to the occurrence of an abnormality when the occurrence of the sudden temperature drop state is determined in the temperature change determination process. Processing will be executed. As the abnormality occurrence handling process, for example, a process for notifying that there is an abnormality or a process for checking the heating operation of the heating means even if a heating start command is commanded is performed. It is possible to take safety measures to avoid continuing the use of the vessel.

  Incidentally, it is conceivable to execute the temperature discrimination process when the heating means is performing a heating operation. However, when the heating operation is being performed, even if the object to be heated is lifted, the temperature detecting means There is a possibility that the detected temperature may continue to be detected due to the heating of the heating means, and the temperature suddenly falling state cannot be properly detected.

  Therefore, according to the first characteristic configuration, the abnormal state of the mounting state detection unit is detected early after the heating operation of the heating unit is stopped by effectively using the temperature detection unit provided for cooking. It came to be able to provide the cooking device which was possible.

  In addition to the first feature configuration, the second feature configuration of the present invention is a configuration in which the heating control unit switches the heating unit from the heating operation state to the heating stop state and then switches to the heating operation state. If the occurrence of the sudden temperature drop state is determined, the occurrence is counted as once, and when the number of occurrences of the sudden temperature drop state is equal to or greater than the set number, the abnormality occurrence handling process is executed. There is in point.

  According to the second characteristic configuration, if the heating control unit determines the occurrence of the temperature suddenly decreasing state after switching the heating unit from the heating operation state to the heating stop state until the next switching to the heating operation state. The occurrence is counted once. That is, the heating control unit executes the temperature change determination process every time the heating operation state is switched from the heating operation state to the heating stop state, and counts it once when the occurrence of the temperature suddenly decreasing state is determined. When the temperature change determination process is repeatedly performed every time the heating operation state is switched to the heating stop state, the number of times that the temperature sudden decrease state has occurred is sequentially counted.

  Then, when the occurrence of the sudden temperature drop state is determined once, the abnormality occurrence handling process is executed, so that even if the occurrence of the sudden temperature drop state is determined by the erroneous determination, the abnormal state is not detected. Regardless of the above, there is a risk of executing the abnormality occurrence handling process, but when the number of occurrences of the temperature sudden drop state is equal to or more than the set number of times, the abnormality occurrence handling process is configured to perform the disadvantages described above. It is possible to execute the abnormality occurrence handling process only when there is no abnormal condition and no usability.

  Therefore, according to the second feature configuration, although there is no actual abnormal state, there is less possibility of executing the abnormality occurrence handling process due to erroneous determination, and it is possible to provide a user-friendly cooking device.

In addition to the first feature configuration or the second feature configuration, the third feature configuration of the present invention supplies power to the heating control unit when a power-on condition is satisfied by a heating start command of the heating command unit, and Power supply control means for cutting off the supply of power to the heating control means when a power-off condition is satisfied by a heating stop command of the heating command means is provided,
The power control means is
When it is detected by the placement state detection means when the power-off condition is satisfied, the supply of power to the heating control means is shut off, and If it is detected that the installation state is detected by the installation state detection unit when the power-off condition is satisfied, the power supply to the heating control unit is continued and the power supply is continued. When the set delay time elapses from when the turn-off condition is satisfied, or when the predetermined power holding release condition is satisfied until the set delay time elapses, the supply of power to the heating control unit is cut off The point is that it is configured to do.

  According to the third characteristic configuration, the power control means supplies power to the heating control means when the power-on condition is satisfied by the heating start command of the heating command means, but when the power supply to the heating control means is shut off, The timing for cutting off the power supply differs according to the detection result of the mounting state detection means when the power-off condition is satisfied.

  That is, when it is detected that the non-placed state is detected by the placement state detection unit when the power-off condition is satisfied, the placement state detection unit is thus in the non-placement state. When this is detected, it is considered that the mounting state detection means is in a normally operating state. Therefore, when the power-off condition is satisfied, the supply of power to the heating control means is interrupted.

  On the other hand, when it is detected that the installation state is detected by the installation state detection unit when the power-off condition is satisfied, the supply of power to the heating control unit is continued, When the set delay time elapses from when the turn-off condition is satisfied, or when the predetermined power holding release condition is satisfied until the set delay time elapses, the supply of power to the heating control means is cut off. It will be.

  That is, when it is detected that the placement state is detected by the placement state detection means, the article to be heated is placed on the placement section, or the article to be heated is placed on the placement section. In spite of this, it is conceivable that the placement state detection means erroneously detects that it is in the placement state, that is, an abnormality due to a failure or the like has occurred. Therefore, even if the power-off condition is satisfied, the interruption of the power supply is delayed only during the set delay time after the power-off condition is satisfied.

  As a usage pattern of the heating cooker, the user may instruct the heating stop command by the heating command means after heating cooking, and immediately lift the heated object from the placement unit to take out the cooked food. If it is used in a usage form such as changing the placement state of the object to be heated, such as moving to another place, the user will be heated before the set delay time elapses. When the object to be heated is placed, for example, when it is lifted from the placing part or moved to another place, the placement state detecting means detects that the object is not placed. become.

  Incidentally, the set delay time is predicted as the elapsed time from when the power-off condition is satisfied until the user performs the above-described operation for changing the placement state of the object to be heated in the above-described usage mode. For example, several minutes to 10 minutes.

  Then, when a predetermined power holding release condition is satisfied until the set delay time elapses, the supply of power to the heating control unit is cut off. As the predetermined power holding release condition, a condition is assumed that it is apparent that the object to be heated has been removed from the placement unit. For example, it may be detected by the mounting state detection means that it is in a non-mounting state, or the occurrence of the temperature suddenly decreasing state may be determined by the temperature change determination processing as described above. .

  In other words, immediately after the user commands the heating stop command of the heating command means, there is a case where the placement state change operation of the object to be heated is performed as described above. When it is assumed that it is obvious that the object to be heated has been removed from the placement portion, it is possible to detect that the set delay time has elapsed. Even so, wasteful power consumption can be suppressed by cutting off the supply of power to the heating control means without waiting until the set delay time elapses.

  In addition, as described above, if there is no abnormality, even if it is detected that the mounting state is detected by the mounting state detecting means when the power-off condition is satisfied, the heating is performed for a long time. Since the supply of power to the control means does not continue, power consumption can be suppressed. In particular, if a battery is provided as a power source, the power consumption of the battery is suppressed, and the battery replacement period is made as long as possible to improve usability.

  Therefore, according to the third characteristic configuration, the use state change operation of the object to be heated is performed after the heating instruction command is commanded by the heating command means while suppressing wasteful power consumption. Moreover, it came to be able to provide the heating cooker which can detect that the mounting state change work was performed and can perform an appropriate process.

In addition to the first feature configuration or the second feature configuration, the fourth feature configuration of the present invention supplies power to the heating control unit when a power-on condition is satisfied by a heating start command of the heating command unit, and Power supply control means for cutting off the supply of power to the heating control means when a power-off condition is satisfied by a heating stop command of the heating command means is provided,
The power control means is
When it is detected by the placement state detection means that the power-off condition is satisfied, and the power supply to the heating control means is started after the power supply to the heating control means is started. When the power-off condition is satisfied in a state where the delay operation release condition detected as being in the non-mounted state by the mounting state detection means is satisfied until the switching condition is satisfied Shuts off the supply of power to the heating control means, and
The power-off state is not detected by the placement state detection means from the start of power supply to the heating control means until the power-off condition is satisfied. When the condition is satisfied, the supply of power to the heating control unit is continued, and the set delay time elapses from when the power-off condition is satisfied, or until the set delay time elapses. In the meantime, when a predetermined power holding release condition is satisfied, the supply of power to the heating control means is cut off.

  According to the fourth feature configuration, the power control means supplies power to the heating control means when the power-on condition is satisfied by the heating start command of the heating command means, but when the power supply to the heating control means is cut off, The timing for cutting off the power supply differs according to the detection result of the mounting state detection means when the power-off condition is satisfied.

  In other words, when it is detected by the placement state detection means that the non-placement state is detected when the power-off condition is satisfied, the placement state detection means thus does not place it. When the state is detected, it is considered that the mounting state detection unit is operating normally. Therefore, when the power-off condition is satisfied, the supply of power to the heating control unit is interrupted.

  On the other hand, the delay operation release condition detected by the placement state detection means from the start of power supply to the heating control means until the power-off condition is satisfied is detected by the placement state detection means. In the case where the power-off condition is satisfied in a state in which the power-off condition is satisfied, the power-off condition is also satisfied in this case because the mounting state detection unit is considered to be in a normally operating state. And shuts off the power supply to the heating control means.

  In addition, in the state in which it is not detected that the non-mounted state is detected by the mounting state detecting unit from the start of power supply to the heating control unit until the power-off condition is satisfied. When the power-off condition is satisfied, the supply of power to the heating control unit is continued, and the set delay time elapses from when the power-off condition is satisfied, or the set delay time elapses. If a predetermined power holding release condition is satisfied in the meantime, the power supply to the heating control means is cut off.

  That is, it is said that the non-mounted state is not detected by the mounting state detecting unit before the power-off condition is satisfied after the power supply to the heating control unit is started. Detects that the object to be heated is placed on the placement part or that the placement state detection means is in the placement state even though the object to be heated is not placed on the placement part. That is, it is considered that an abnormality due to a failure or the like has occurred. Therefore, even if the power-off condition is satisfied, the interruption of the power supply is delayed only for the set delay time after the power-off condition is satisfied.

  As a form of use of the heating cooker, the user instructs the heating stop command of the heating command means to finish the heating cooking and satisfy the power-off condition, and immediately after that the user takes out the food to be cooked. If it is used in a form of usage such as lifting the object from the placement part or moving it to another place, the work will be carried out until the set delay time elapses. In addition, when the user performs a placement state change operation of the article to be heated, such as lifting the article to be heated from the placement unit or moving it to another place, the placement state detection means causes the non-placement state. It is detected that there is.

  Incidentally, the set delay time is predicted as the elapsed time from when the power-off condition is satisfied until the user performs the above-described operation for changing the placement state of the object to be heated in the above-described usage mode. For example, several minutes to 10 minutes.

  Then, when a predetermined power holding release condition is satisfied until the set delay time elapses, the supply of power to the heating control unit is cut off. As the predetermined power holding release condition, a condition is assumed that it is apparent that the object to be heated has been removed from the placement unit. For example, it may be detected by the mounting state detection means that it is in a non-mounting state, or the occurrence of the temperature suddenly decreasing state may be determined by the temperature change determination processing as described above. .

  That is, since the user may perform the placement state change operation of the object to be heated as described above immediately after instructing the heating stop command of the heating command means for satisfying the power-off condition, When the mounting state detection means can detect the switching to the non-mounting state and it is clear that the object to be heated has been removed from the mounting portion, the setting is performed. Even in the course of the delay time, useless power consumption can be suppressed by cutting off the supply of power to the heating control means without waiting for the set delay time to elapse.

  In addition, when the heating means is performing the heating operation, if the placement state detection means detects that it is in the non-loading state, the power supply is interrupted only during the set delay time. If the power-off condition is satisfied without doing this, the power supply to the heating control means is cut off immediately, so that the power consumption can be further suppressed.

  Moreover, as described above, if there is no abnormality, even if it is detected that the mounting state is detected by the mounting state detection means when the power-off condition is satisfied, the heating is performed for a long time. Since the supply of power to the control means does not continue, power consumption can be suppressed. In particular, if a battery is provided as a power source, the power consumption of the battery is suppressed, and the battery replacement period is made as long as possible to improve usability.

  Therefore, according to the 4th characteristic structure, it is a use form which performs the mounting state change work of a to-be-heated object, after instructing a heating stop command with a heating command means, suppressing useless power consumption. Moreover, it came to be able to provide the heating cooker which can detect that the mounting state change work was performed and can perform an appropriate process.

In addition to the first feature configuration or the second feature configuration, the fifth feature configuration of the present invention supplies power to the heating control unit when a power-on condition is satisfied by a heating start command of the heating command unit, and Power supply control means for cutting off the supply of power to the heating control means when a power-off condition is satisfied by a heating stop command of the heating command means is provided,
The heating control means
The mounting state continuation time in which the previous mounting state is continuously detected by the previous mounting state detection means is integrated, and when the integrated value of the mounting state duration reaches the abnormality determination set time, abnormality countermeasure processing is performed. Configured to execute, and
Even when the supply of power is interrupted, the integrated value of the mounting state continuation time is held, and when the power is supplied, the mounting state detection means detects the non-mounted state. The integrated value is reset when detected, and is configured to integrate the mounting state duration when the mounting state is detected by the mounting state detection means when power is supplied. And
The power control means is
When it is detected by the mounting state detection means that the non-mounting state is detected when the power-off condition is satisfied, and the integrated value of the mounting state duration is set for the abnormality determination When the power-off condition is satisfied when the power-off condition is satisfied when the power-off condition is less than or equal to a set time for changing the cut-off condition set to a time shorter than the time, and the power supply to the heating control unit is cut off,
If the integrated value of the standing state continuation time exceeds the set time for changing the cutoff condition, the power-off condition is determined when the placing state detecting means detects that the placing state is the preceding state. If satisfied, continue to supply power to the heating control means until the set delay time elapses from when the power-off condition is satisfied or until the set delay time elapses When the predetermined power holding release condition is satisfied, the power supply to the heating control means is cut off.

  According to the fifth characteristic configuration, the heating control unit integrates the mounting state duration time in which the previous mounting state is continuously detected by the previous mounting state detection unit, and an integrated value of the mounting state duration time. Is configured to execute abnormality countermeasure processing when the abnormality determination set time is reached. In addition, when the mounting state in which the object to be heated is mounted on the mounting portion is detected by the mounting state detection means while power is supplied, the mounting state is continuously detected. When the non-placed state in which the object to be heated is not placed on the placement unit is detected by the placement state detection unit when power is supplied, the placement state is detected. Reset the accumulated value of the state duration.

  That is, when the integrated value of the mounting state duration time in which the previous mounting state is continuously detected by the previous mounting state detection means becomes long enough to reach the abnormality determination set time, an object to be heated is placed on the mounting unit. Is placed or the object to be heated is erroneously detected to be in the placement state even though the object to be heated is not placed in the placement part. It is thought that has occurred. Therefore, in such a case, abnormality countermeasure processing is executed. As the abnormality countermeasure process, there are processes such as encouraging the user to lift the object to be heated and checking the subsequent heating operation. By executing the abnormality countermeasure processing in this way, it is possible to prevent the use from continuing in an abnormal state.

  Then, the mounting state duration time in which the previous mounting state is continuously detected by the previous mounting state detection means is integrated, and when the integrated value of the mounting state duration reaches the set time for abnormality determination, the countermeasure against the abnormality Since it is configured to execute the process, even if the temperature discrimination process is performed, even if it is difficult to properly detect whether or not the object to be heated is lifted, an abnormality of the mounting state detection unit is detected. It becomes possible to detect appropriately.

For example, after the heating operation of the heating means is stopped while the object to be heated is placed on the mounting portion, the object to be heated is lifted after a short time after the temperature of the object to be heated has decreased. If it is a use form, even if the object to be heated may be lifted at that time, it is difficult to detect the temperature suddenly falling state by the discrimination by the temperature discrimination process, in other words, the placement state detecting means is out of order. Sometimes it is impossible to detect that the object to be heated has been lifted.
However, the above-described usage state is configured by integrating the mounting state duration time and executing the abnormality countermeasure process when the integrated value of the mounting state duration reaches the abnormality determination set time. However, when there is an abnormality due to a failure or the like while avoiding the continued accumulation of the loading state duration when the loading state detection means is operating normally, the loading state duration time Therefore, the abnormality countermeasure process can be appropriately executed when the integrated value reaches the abnormality determination set time.

  The power supply control unit supplies power to the heating control unit when the power-on condition is satisfied by the heating start command of the heating command unit. However, when the power supply to the heating control unit is cut off, the power-off condition is satisfied. The timing for cutting off the power supply differs according to the detection result of the mounting state detection means at that time.

  In other words, when the power-off condition is satisfied by the heating stop command of the heating command means when the mounting status detection means detects that it is in the non-loading state, the mounting status detection means does not When it is detected that the mounting state is detected, it is considered that the mounting state detection unit is operating normally. Therefore, when the power-off condition is satisfied, the supply of power to the heating control unit is cut off. .

  On the other hand, when the power-off condition is satisfied when the integrated value of the mounting state duration is equal to or less than the set time for changing the cutoff condition set to a time shorter than the set time for abnormality determination, the power to the heating control means is Shut off the supply. Further, if the integrated value of the mounting state duration exceeds the set time for changing the cutoff condition, the power-off condition is satisfied when the mounting state detecting means detects the mounting state. If it is, the supply of power to the heating control means is continued, and the set delay time elapses from when the power-off condition is satisfied, or until the set delay time elapses. When the power holding release condition is satisfied, the power supply to the heating control unit is cut off.

  In addition, when it is detected that the placement state detection unit detects the placement state, the article to be heated is placed on the placement unit, or the article to be heated is placed on the placement unit. Although it is not placed, it is considered that the placement state detecting means erroneously detects that it is in the placed state, that is, it is considered that an abnormality due to a failure or the like has occurred. If the integrated value is equal to or shorter than the set time for changing the cutoff condition set to a time shorter than the set time for abnormality determination, the power-off condition is detected when the mounted state is detected by the mounted state detecting means. Is satisfied, the supply of electric power to the heating control means is cut off.

  If there is no abnormality and the power-off condition is satisfied while the object to be heated is placed on the placement part, when cooking is repeatedly performed, Since it is considered that the integrated value of the mounting state duration time is reset when the user performs the mounting state change operation of the object to be heated, the integrated value of the mounting state duration time is set to the setting time for changing the cutoff condition. If the time is shorter than that, power consumption can be suppressed as much as possible by cutting off the supply of power to the heating control means when the power-off condition is satisfied.

  On the other hand, if the integrated value of the mounting state duration time exceeds the cutoff condition change setting time, the power-off condition is satisfied when the mounting state detecting unit detects that the mounting state is detected. When the power-off condition is satisfied, the interruption of the power supply is delayed only for the set delay time after the power-off condition is satisfied.

  As a usage pattern of the heating cooker, the user is heated until the set delay time elapses after a heating stop command for heating command means for satisfying the power-off condition is completed after cooking is completed. If it is used in a form of usage such as performing an operation to change the placement state of the object to be heated, such as lifting an object from the placement unit or moving it to another place, the set delay time will elapse. In the meantime, a predetermined power holding release condition is satisfied, and power supply to the heating control means is cut off.

  As the predetermined power holding release condition, a condition is assumed that it is apparent that the object to be heated has been removed from the placement unit. For example, it may be detected by the mounting state detection means that it is in a non-mounting state, or the occurrence of the temperature suddenly decreasing state may be determined by the temperature change determination processing as described above. .

  By the way, as the set delay time, a time estimated as an elapsed time from when the power-off condition is satisfied to when the heated object is lifted or moved in a general usage pattern, for example, several minutes to Set to about 10 minutes.

That is, immediately after the user commands the heating stop command of the heating command means, there is a case where the operation of changing the placement state of the heated object as described above is performed. It is possible to detect that there has been a placement state change operation. Also, it is not until immediately after the set delay time elapses even if the placement state change operation of the object to be heated is performed after the temperature of the object to be heated has decreased, not immediately after instructing the heating stop command. Thus, it is possible to detect that there has been an operation for changing the placement state of the object to be heated.
In addition, when it is assumed that the object to be heated has been removed from the placement unit, the heating control means does not wait until the set delay time elapses even during the set delay time elapses. By cutting off the supply of power to the battery, wasteful power consumption can be suppressed.

  If it is detected that the object to be heated is not placed on the placement portion until the set delay time elapses, the integrated value of the placement state duration time is reset. As a result, it is possible to avoid performing unnecessary abnormality countermeasure processing even though the object to be heated is not placed on the placement portion. That is, since the user may perform the placement state change operation of the object to be heated as described above immediately after instructing the heating stop command of the heating command means for satisfying the power-off condition, When no abnormality has occurred, the integrated value of the mounting state duration is reset by the user's operation.

  On the other hand, when the set delay time elapses without satisfying the predetermined power holding release condition, the supply of power to the heating control means is interrupted without resetting the integrated value of the mounting state duration time. Since it is also possible that an abnormality has occurred, such as a failure of the mounting state detection means, the integrated value of the mounting state duration is retained and added to the integrated value at the next start of power supply. Then, the mounting state duration time is integrated.

  As described above, if there is no abnormality, the heating control means is used for a long time even if the placement state detection means detects that the placement state is detected when the power-off condition is satisfied. Since the supply of power to the battery does not continue, power consumption can be suppressed. In particular, if a battery is provided as a power source, the power consumption of the battery is suppressed, and the battery replacement period is made as long as possible to improve usability.

  Therefore, according to the fifth feature configuration, when there is a possibility that an abnormality has occurred, it is possible to prevent continued use in an abnormal state by performing abnormality countermeasure processing, It has been possible to provide a cooking device capable of accurately detecting this in a state in which no occurrence of power occurs and suppressing wasteful power consumption.

In addition to the first feature configuration or the second feature configuration, the sixth feature configuration of the present invention supplies power to the heating control unit when a power-on condition is satisfied by a heating start command of the heating command unit, and Power supply control means for cutting off the supply of power to the heating control means when a power-off condition is satisfied by a heating stop command of the heating command means is provided,
The heating control means
The mounting state continuation time in which the previous mounting state is continuously detected by the previous mounting state detection means is integrated, and when the integrated value of the mounting state duration reaches the abnormality determination set time, abnormality countermeasure processing is performed. Configured to execute, and
Even when the supply of power is interrupted, the integrated value of the mounting state continuation time is held, and when the power is supplied, the mounting state detection means detects the non-mounted state. The integrated value is reset when detected, and is configured to integrate the mounting state duration when the mounting state is detected by the mounting state detection means when power is supplied. And
The power control means is
When it is detected that the non-mounting state is detected by the mounting state detection unit when the power-off condition is satisfied, the power-off condition is set after the power supply to the heating control unit is started. When the power-off condition is satisfied in a state where the delay operation release condition detected as being in the non-placed state by the placement state detection means before being fulfilled, and before When the power-off condition is satisfied when the integrated value of the stated state duration is equal to or less than the set time for changing the cutoff condition set to a time shorter than the set time for abnormality determination, the heating control means And cut off the power supply of
In the state where the integrated value of the setting state duration time exceeds the set time for changing the cutoff condition and before the power-off condition is satisfied after the power supply to the heating control unit is started When the power-off condition is satisfied in a state where the non-mounting state is not detected by the installation state detection unit, the power supply to the heating control unit is continued and the power-off state is continued. When the set delay time elapses after the condition is satisfied, or when a predetermined power holding release condition is satisfied until the set delay time elapses, the power supply to the heating control unit is cut off. It is in the point comprised as follows.

  According to the sixth characteristic configuration, the heating control means accumulates the mounting state duration time in which the previous placement state is continuously detected by the previous placement state detection means, and an integrated value of the placement state duration time. Is configured to execute abnormality countermeasure processing when the abnormality determination set time is reached. In addition, when the mounting state in which the object to be heated is mounted on the mounting portion is detected by the mounting state detection means while power is supplied, the mounting state is continuously detected. When the non-placed state in which the object to be heated is not placed on the placement unit is detected by the placement state detection unit when power is supplied, the placement state is detected. Reset the accumulated value of the state duration.

  That is, when the integrated value of the mounting state duration time in which the previous mounting state is continuously detected by the previous mounting state detection means becomes long enough to reach the abnormality determination set time, an object to be heated is placed on the mounting unit. Is placed or the object to be heated is erroneously detected to be in the placement state even though the object to be heated is not placed in the placement part. It is thought that has occurred. Therefore, in such a case, abnormality countermeasure processing is executed. As the abnormality countermeasure process, there are processes such as encouraging the user to lift the object to be heated and checking the subsequent heating operation. By executing the abnormality countermeasure processing in this way, it is possible to prevent the use from continuing in an abnormal state.

For example, after the heating operation of the heating means is stopped while the object to be heated is placed on the mounting portion, the object to be heated is lifted after a short time after the temperature of the object to be heated has decreased. If it is a use form, even if the object to be heated may be lifted at that time, it is difficult to detect the temperature suddenly falling state by the discrimination by the temperature discrimination process, in other words, the placement state detecting means is out of order. Sometimes it is impossible to detect that the object to be heated has been lifted.
However, the above-described usage state is configured by integrating the mounting state duration time and executing the abnormality countermeasure process when the integrated value of the mounting state duration reaches the abnormality determination set time. However, when there is an abnormality due to a failure or the like while avoiding the continued accumulation of the loading state duration when the loading state detection means is operating normally, the loading state duration time Therefore, the abnormality countermeasure process can be appropriately executed when the integrated value reaches the abnormality determination set time.

  The power supply control unit supplies power to the heating control unit when the power-on condition is satisfied by the heating start command of the heating command unit. However, when the power supply to the heating control unit is cut off, the power-off condition is satisfied. The timing for cutting off the power supply differs according to the detection result of the mounting state detection means at that time.

  In other words, when the power-off condition is satisfied by the heating stop command of the heating command means when the mounting status detection means detects that it is in the non-loading state, the mounting status detection means does not When it is detected that the mounting state is detected, it is considered that the mounting state detection unit is operating normally. Therefore, when the power-off condition is satisfied, the supply of power to the heating control unit is cut off. .

  On the other hand, the delay operation release condition detected by the placement state detection means from the start of power supply to the heating control means until the power-off condition is satisfied is detected by the placement state detection means. In the case where the power-off condition is satisfied in a state in which the power-off condition is satisfied, the power-off condition is also satisfied in this case because the mounting state detection unit is considered to be in a normally operating state. And shuts off the power supply to the heating control means.

  Then, when the power-off condition is satisfied when the integrated value of the mounting state duration is equal to or shorter than the set time for changing the interruption condition set to a time shorter than the set time for abnormality determination, the power to the heating control means is satisfied. Shut off the supply. In addition, the integrated value of the above-mentioned installation state duration time is in a state where it exceeds the set time for changing the cutoff condition, and after the power supply to the heating control means is started until the power-off condition is satisfied. When the power-off condition is satisfied in a state where the non-placed state is not detected by the placement state detection unit, the supply of power to the heating control unit is continued, When the set delay time elapses from when the power-off condition is satisfied, or when the predetermined power holding release condition is satisfied until the set delay time elapses, the power supply to the heating control means is performed. Cut off.

  In addition, when it is detected that the placement state detection unit detects the placement state, the article to be heated is placed on the placement unit, or the article to be heated is placed on the placement unit. Although it is not placed, it is considered that the placement state detecting means erroneously detects that it is in the placed state, that is, it is considered that an abnormality due to a failure or the like has occurred. If the integrated value is equal to or shorter than the set time for changing the cutoff condition set to a time shorter than the set time for abnormality determination, the power-off condition is detected when the mounted state is detected by the mounted state detecting means. Is satisfied, the supply of electric power to the heating control means is cut off.

  If there is no abnormality and the power-off condition is satisfied while the object to be heated is placed on the placement part, when cooking is repeatedly performed, It is possible that the integrated value of the mounting state duration will be reset when the user changes the mounting state of the object to be heated. If the power-off condition is satisfied, the power consumption is suppressed as much as possible by cutting off the supply of power to the heating control means.

  On the other hand, in the state where the integrated value of the above-described installation state duration exceeds the set time for changing the cutoff condition, and after the power supply to the heating control means is started until the power-off condition is satisfied When the power-off condition is satisfied in a state where the non-mounted state is not detected by the mounting state detection unit, a set delay time has elapsed since the power-off condition is satisfied The interruption of the power supply is delayed only during this period.

  As a form of use of the heating cooker, the user instructs the heating stop command of the heating command means to finish the heating cooking and satisfy the power-off condition, and immediately after that the user takes out the food to be cooked. If it is used in a form of usage such as lifting the object from the placement part or moving it to another place, the work will be carried out until the set delay time elapses. In addition, when the user performs a placement state change operation of the article to be heated, such as lifting the article to be heated from the placement unit or moving it to another place, the placement state detection means causes the non-placement state. It is detected that there is.

  Incidentally, the set delay time is predicted as the elapsed time from when the power-off condition is satisfied until the user performs the above-described operation for changing the placement state of the object to be heated in the above-described usage mode. For example, several minutes to 10 minutes.

  That is, immediately after the user commands the heating stop command of the heating command means, there is a case where the operation of changing the placement state of the heated object as described above is performed. It is possible to detect that there has been a placement state change operation. In addition, when it is assumed that the object to be heated has been removed from the placement unit, the heating control means does not wait until the set delay time elapses even during the set delay time elapses. By cutting off the supply of power to the battery, wasteful power consumption can be suppressed.

  Then, when a predetermined power holding release condition is satisfied until the set delay time elapses, the supply of power to the heating control unit is cut off. As the predetermined power holding release condition, a condition is assumed that it is apparent that the object to be heated has been removed from the placement unit. For example, it may be detected by the mounting state detection means that it is in a non-mounting state, or the occurrence of the temperature suddenly decreasing state may be determined by the temperature change determination processing as described above. .

  In other words, immediately after the user commands the heating stop command of the heating command means, there is a case where the placement state change operation of the object to be heated is performed as described above. When it is assumed that it is obvious that the object to be heated has been removed from the placement portion, it is possible to detect that the set delay time has elapsed. Even so, wasteful power consumption can be suppressed by cutting off the supply of power to the heating control means without waiting until the set delay time elapses.

  If it is detected by the mounting state detection means that the set delay time elapses, the integrated value of the mounting state duration time is reset. As a result, it is possible to avoid performing unnecessary abnormality countermeasure processing in spite of no abnormality occurring in the placement state detection means. That is, since the user may perform the placement state change operation of the object to be heated as described above immediately after instructing the heating stop command of the heating command means for satisfying the power-off condition, When no abnormality has occurred, the integrated value of the mounting state duration is reset by the user's operation.

  As described above, if there is no abnormality, the heating control means is used for a long time even if the placement state detection means detects that the placement state is detected when the power-off condition is satisfied. Since the supply of power to the battery does not continue, power consumption can be suppressed. In particular, if a battery is provided as a power source, the power consumption of the battery is suppressed, and the battery replacement period is made as long as possible to improve usability. Then, if there is an abnormality such as a failure of the mounting state detection means, the mounting state continuation is continued by integrating the mounting state duration without resetting after the power supply is cut off. The accumulated time is accumulated until the abnormality determination set time is reached, and abnormality countermeasure processing is executed.

  Therefore, according to the sixth feature configuration, when there is a possibility that an abnormality has occurred, it is possible to prevent the continuation of use in an abnormal state by performing abnormality countermeasure processing, and an abnormality occurs. In a state where it is clear that power consumption has not been achieved, it has become possible to provide a cooking device that can further suppress power consumption without continuing power consumption.

  According to a seventh feature configuration of the present invention, in addition to any one of the third feature configuration to the sixth feature configuration, the power supply control means is shorter than when the integrated value of the set state duration is longer. The configuration is such that the set delay time is changed and set in a long form.

  According to the seventh characteristic configuration, since the setting delay time is changed and set to be longer when the integrated value of the above-described standing state duration is longer than when the integrated value is long, the integrated value of the above-described standing state duration is If the state is sufficiently shorter than the abnormality determination set time, it is possible to reduce power consumption by shortening the time for delaying power supply.

  Then, if the integrated value of the loading state duration is long and is approaching the abnormality determination setting time, the processing is performed by lifting the object to be heated or moving it to another place by increasing the setting delay time. Is performed to increase the probability of detecting the non-mounted state by the mounting state detecting means and reset the integrated value of the mounted state duration as much as possible. It becomes easy to avoid executing the processing.

  According to an eighth feature configuration of the present invention, in addition to any one of the third feature configuration to the seventh feature configuration, the power control unit is configured to wait until the set delay time elapses after the power-off condition is satisfied. In the meantime, if it is determined by the heating control means that the temperature suddenly falls in the temperature change determination process, the heating control means is supplied with power assuming that the predetermined power holding release condition is satisfied. It is in the point comprised so that it may interrupt.

  According to the eighth characteristic configuration, when the occurrence of the temperature suddenly falling state is determined between when the power-off condition is satisfied and until the set delay time elapses, the mounting state detecting means is in an abnormal state. Therefore, it is possible to suppress wasteful power consumption by shutting off the supply of power to the heating control means.

  According to a ninth feature configuration of the present invention, in addition to any one of the third feature configuration to the eighth feature configuration, the power supply control unit is configured to wait until the set delay time elapses after the power-off condition is satisfied. In the meantime, if it is detected by the placement state detection means that the non-placement state is present, the supply of power to the heating control means is cut off because the predetermined power holding release condition is satisfied. It is in the point which is comprised.

  According to the ninth characteristic configuration, during the period from when the power-off condition is satisfied until the set delay time elapses, the placement state detection unit detects that the device is in the non-placed state. And the placement state detection means is operating normally, and the heated object is lifted upward from the placement portion, and at that time, by shutting off the supply of power to the heating control means Wasteful power consumption can be suppressed.

  The tenth characteristic configuration of the present invention includes a plurality of the heating means in addition to any of the third characteristic configuration to the ninth characteristic configuration, and each of the plurality of heating means is provided as the heating command means. Separately, there are provided a plurality of heating command means for commanding the heating start command and the heating stop command, and the power supply control means is a heating operation in which at least one of the plurality of heating command means commands a heating start command The power-off condition is satisfied when all of the plurality of heating command means are switched from a state to a full stop state in which a heating stop command is commanded, and the power is turned on when the state is switched from the full stop state to the heating operation state. The point is that it is configured so that the condition is satisfied.

  According to the tenth characteristic configuration, a plurality of heating command means for commanding the heating start command and the heating stop command are provided for each of the plurality of heating means, and the power supply control means includes all the heating means. When at least any one of the plurality of heating command means commands the heating start command from the fully stopped state in which the heating is stopped and switches to the heating operation state, it is necessary to supply power to the heating control means. Assume that the power-on conditions are met. Further, when the power control means is switched from the heating operation state to the all-stop state, it is assumed that the power-off condition is satisfied because it is not necessary to supply power to the heating control means.

  For example, if a dedicated power on / off operation means for instructing the power off condition and the power on condition is provided, the power supply by operating the power on / off operation means after instructing the heating stop command of the heating means It may be possible to forget the operation of instructing the turn-off command, which may cause the power supply to the heating control means to continue unexpectedly for a long time. Since it is determined that the power-on condition is satisfied, the power-off condition is satisfied by instructing the heating unit to stop heating, so that the power supply to the heating control unit continues for a long time due to forgetting the operation. There is an advantage that it is possible to suppress power consumption due to this. Further, there is no need to provide a dedicated power on / off operation means for commanding the power off condition and the power on condition, and there is an advantage that the configuration can be simplified.

Is done.

  When the heating control unit 100 stops the heating operation of the heating unit A and the mounting state is detected by the mounting state detection unit D, the heating control unit 100 is based on the detection information of the temperature sensor 11. And a temperature change determination process for determining whether or not the temperature of the object to be heated placed in Gotoku 6 is in a state of rapid decrease in temperature, and based on the determination result of the temperature change determination process Thus, it is configured to execute an abnormality determination process for determining whether or not there is an abnormal state.

  Furthermore, if the heating control unit 100 determines that the temperature suddenly decreases after the heating unit A is switched from the heating operation state to the heating stop state and then switched to the heating operation state, the heating control unit 100 recognizes the occurrence. When the number of occurrences of the sudden temperature drop state is equal to or greater than a preset number, the abnormality occurrence handling process is executed.

  Further, in this stove, when the power-on condition is satisfied by the command of the point fire switch 32, power is supplied to the heating control means 100, and when the power-off condition is satisfied by the command of the point fire switch 32, the heating control means 100 is supplied. Power supply control means PK for cutting off the supply of power to the power supply means PK is provided, and the power supply control means PK is in the non-mounted state by the mounting state detection unit D when the power-off condition is satisfied. If detected, the power supply to the heating control means 100 is cut off, and when the power-off condition is satisfied, the placement state detection unit D detects that the placement state is described above. If it is, the supply of power to the heating control means 100 is continued and the set delay time elapses from when the power-off condition is satisfied or until the set delay time elapses. In When a predetermined power supply holding release condition is satisfied had, is configured to cut off the power supply to the heating control means 100.

  Then, the power control unit PK causes the heating control unit 100 to generate the sudden temperature drop state in the temperature change determination process from when the power-off condition is satisfied until the set delay time elapses. If determined, the power supply to the heating control unit 100 is cut off as the predetermined power holding release condition is satisfied, and further, the set delay from when the power off condition is satisfied. If the mounting state detection unit D detects that the non-mounting state is detected until the time elapses, the heating control unit 100 is informed that the predetermined power holding release condition is satisfied. The power supply is configured to be cut off.

  The set delay time is a time that is expected to be required to lift or move the object to be heated after the power-off condition is satisfied by the operation so that the power consumption does not increase, for example, several minutes to 10 It will be set to about a minute.

  Further, the heating control means 100 accumulates the mounting state duration time during which the mounting state is continuously detected by the mounting state detection unit D while the power is supplied, and continues the mounting state. When the integrated time Tk reaches the abnormality determination set time Ts, an abnormality countermeasure process is executed. That is, even when the supply of electric power is interrupted, the mounting state detecting unit D is configured to maintain the integrated value Tk of the above described mounting state duration time and when the electric power is supplied, the non-mounting state is detected. When the set state is detected, the integrated value Tk is reset, and the set state duration time is integrated. A non-volatile memory Me is provided to hold the integrated value even when the power supply is cut off, and the operation control unit H sets the non-volatile value at that time immediately before the power supply is cut off. The memory Me is written and stored.

Next, a specific configuration will be described.
As shown in FIG. 4, an intermittent switching circuit 41 that can be switched between a power supply state for supplying power from the power source 40 to the operation control unit H and a cutoff state for cutting off the power supply is provided. When at least one of a total of four point fire-extinguishing switches 32 of the three burner switches 32 and one point fire-extinguishing switch 61 for the grill burner 2 is turned on, the power-on condition is satisfied. The power supply state is switched from the cut-off state.

  The intermittent switching circuit 41 includes a switching transistor 42 that intermittently connects a power supply line from the power source 40 to the operation control unit H, and a drive circuit 43 that switches the switching transistor 42 between an on state and an off state. Even in a state where the operation control unit H is not supplied with power and is not operating, when any of the point fire extinguishing switches 32 and 61 is turned on, that is, when a heating start command is instructed, the switching transistor 42 is switched to a conductive state. It is the structure which switches to the state which supplies electric power to the operation control part H.

The operation information of each of the point fire extinguishing switches 32 and 61 is also input to the operation control unit H, and the operation control unit H performs switching until all of the four point extinguishing switches 32 and 61 are turned off. A power holding signal is output to the drive circuit 43 in order to maintain the transistor 42 in a conductive state. That is, when all of the four point fire extinguishing switches 32 and 61 are turned off, that is, when the heating control command is instructed, the operation control unit H stops outputting the power holding signal because the power-off condition is satisfied. It is.
Accordingly, the power management means 101 that manages the power supply state using the operation control unit H is configured, and the power management means 101 and the intermittent switching circuit 41 constitute the power control means PK.

Next, the control of the operation control unit H will be described.
The control according to the present invention is executed for the standard burner 1a and the high thermal power burner 1c. However, the control operation of the operation control unit H for the standard burner 1a and the high thermal power burner 1c is performed. Therefore, in the following, the control operation for the standard burner 1a will be described, and the description of the control operation for the high thermal power burner 1c will be omitted.
The original gas solenoid valve 13 is opened when the fire extinguishing switches 32 and 61 corresponding to at least one of the standard burner 1a, the small burner 1b, the high heating power burner 1c, and the grill burner 2 are in an ON state. When all of the fire extinguishing switches 32 and 61 corresponding to the standard burner 1a, the small burner 1b, the high burner 1c, and the grill burner 2 are all in the OFF state, the valve is kept closed. Description of the control of the electromagnetic valve 13 is omitted.

The control operation of the operation control unit H will be described below based on the flowcharts shown in FIGS.
When the fire extinguishing switch 32 corresponding to the standard burner 1a is turned on and power is supplied from the power source 40, the operation control unit H reads the stored contents of the nonvolatile memory Me and turns on / off the intermittent switching circuit 41. A power holding signal for holding the signal is output (steps 1 and 2). And when the mounting state detection unit D detects the mounting state described above, that is, the state with the object to be heated, the mounting state duration time in which the mounting state is continuously detected is integrated, When the non-mounting state, that is, the state where there is no object to be heated, is detected, the count value Nk of the sticking determination counter counted by the determination result of the temperature determination process as described later is reset to zero, and Then, the integrated value Tk of the previous set state duration is reset to zero (steps 3, 4, 5-1, 5-2).

  When the integrated value Tk of the set state duration time does not reach the abnormality determination set time Ts, it is determined whether or not the count value Nk of the sticking determination counter is equal to or greater than the set number Ns, and the count value Nk is When the set number of times Ns is not exceeded, combustion control for the standard burner is executed (steps 6-1, 6-2, and 7).

  In this combustion control, as shown in FIG. 6, the flow control valve 18 is opened, and an ignition process for igniting the standard burner 1a is performed by applying a drive signal to the spark plug 7 to perform ignition (step 71, 72). If the automatic cooking mode is not set, the opening degree of the flow control valve 18 is adjusted so that the combustion amount of the standard burner 1a becomes the combustion amount according to the command of the combustion amount adjustment operation unit 29 (step 73- 1, 73-2) When the automatic cooking mode is set, the opening degree of the flow control valve 18 is set so that the temperature of the heated object detected by the temperature sensor 11 becomes a preset temperature. Is automatically adjusted to the amount of combustion (thermal power) of the standard burner 1a (step 73-3). If there is a fire extinguishing command, fire extinguishing processing is executed (steps 74 and 79).

  When the mounting state detection unit D detects that there is no object to be heated during the combustion operation, the combustion amount of the standard burner 1a is set to a heating power one level higher than the lowest heating power among the five heating powers. By adjusting the opening degree of the flow control valve 18 so as to reduce the combustion amount in the absence, the front thermal power display unit 36 and the top thermal power display unit 71 corresponding to the standard burner 1a are blinked in the same manner. 6 is informed that the standard burner 1a is in an abnormal state in which no object to be heated is placed (steps 75, 76, 77).

  Then, the combustion amount of the standard burner 1a is reduced to the non-existing combustion amount until the elapsed time after the placement state detection unit D detects the state of no object to be heated reaches the absence determination time. (Step 78), and during that time, when the mounting state detection unit D detects the state with the object to be heated, it returns to the original thermal power and continues the combustion state, and the absence determination time elapses. However, if the placement state detection unit D detects a state where there is no object to be heated, a fire extinguishing process is executed (step 79).

  When the fire extinguishing process is executed for the standard burner 1a, if all the point fire extinguishing switches 32 and 61 are in the off state, it is determined that the power-off condition is satisfied. At that time, the mounting state detection of the standard burner 1a is detected. When the part D detects a state where there is no object to be heated, the integrated value Tk of the mounting state duration time is reset to zero, and the count value Nk of the sticking determination counter is reset to zero. The reset value is written to the non-volatile memory Me, the output of the power holding signal for holding the power-on state output to the intermittent switching circuit 41 is stopped, the operation of holding the power-on state is canceled, and the intermittent switching is performed. The circuit 41 is switched to the cut-off state to turn off the power (steps 8, 9, 10-1, 10-2, 12, 13).

  When the fire extinguishing process is executed for the standard burner 1a, when all the point fire extinguishing switches 32 and 61 are in an off state and it is determined that the power-off condition is satisfied, the placement state detection unit D has an object to be heated. When the state is detected, the operation for holding the power-on state is continuously performed, and it is determined that the power-off condition is satisfied until the set delay time (for example, 3 minutes) elapses. Based on the detection information of the temperature sensor 11, a temperature change determination process is performed to determine whether or not the temperature of the object to be heated placed in the virtues 6 is in a temperature rapidly decreasing state in which the temperature is rapidly decreased (step 11-1). 11-2).

Next, the temperature change determination process will be described.
As shown in FIG. 7, every time a measurement unit time (1 second) elapses, the temperature sensor 11 detects the current temperature of the object to be heated, and sequentially until data for a set number (for example, 10) is obtained. The detected detection value is written and stored (steps 80, 81, 82). When the detection values for the set number are stored, the process for determining whether the temperature difference is equal to or greater than the set amount by comparing the latest detection value with the stored past detection values is performed. Each of the data is performed, and if the temperature difference from at least one of the detected values is equal to or greater than a set amount, it is determined that the temperature of the article to be heated is in a rapidly decreasing state (steps 83, 84, 86). . If it is not determined that the temperature difference is equal to or greater than the set amount even after the determination process is completed for all the set number of data, the oldest data among the stored detection value data for the set number is deleted. The stored data is updated in a state where the latest detection value is written and stored (steps 85 and 87). The processing in steps 80 to 87 is performed every time a new detection value is detected, that is, every time the measurement unit time (1 second) elapses. The above-described temperature suddenly falling state is determined when the pan or the like as the object to be heated is lifted from the state where it is placed on Gotoku 6 and removed to the outside. If it is not determined, it indicates that the object to be heated is still placed on Gotoku 6.

  When it is determined in the temperature determination process that the temperature is rapidly decreasing, the count value Nk of the abnormality occurrence counter is counted up, the count value is written to the nonvolatile memory Me, and the intermittent switching circuit 41 is set. The operation of stopping the output of the power holding signal for holding the output power-on state and stopping the power-on state is canceled, the intermittent switching circuit 41 is switched to the cut-off state, and the power is turned off (step 11- 3, 11-4, 12, 13).

  If it is determined in step 6-1 that the integrated value Tk of the above-mentioned standing state duration has reached the abnormality determination set time Ts, the above-mentioned abnormality countermeasure processing is performed by the speaker 37 serving as the notification means. Please notify the guidance information for urging to raise the object to be heated from the five virtues 6, etc., and also perform the notification operation to blink the front thermal power display unit 36 and the top thermal power display unit 71 corresponding to the standard burner 1 a in the same manner. Execute (step 14). And when the mounting state detection part D detects the state with a to-be-heated object, even if the elapsed time after starting the alerting | reporting setting time Tm (for example, 48 hours) passes, (step) 15) As an abnormality occurrence handling process, the speaker 37 is notified of failure information such as “failure has occurred”, and the front thermal power display unit 36 and the top thermal power display unit 71 corresponding to the standard burner 1a are similarly set. An alarm process for notifying that an abnormality has occurred by flashing is executed, and an operation according to a command from the fire extinguishing switch 32 is not accepted (steps 16 and 17). The process of making the operation of step 17 unacceptable corresponds to the heating operation check process.

  In Step 6-2, when it is determined that the count value Nk of the abnormality occurrence counting counter is equal to or greater than the set number Ns (for example, 3 times), a failure occurs in the speaker 37 as an abnormality occurrence handling process. The failure process such as “I did it” is performed, and the front thermal power display unit 36 and the top thermal power display unit 71 corresponding to the standard burner 1a are similarly flashed to perform an alarm process to notify that an abnormality has occurred. Further, in this state, the operation by the command of the fire extinguishing switch 32 is not accepted (steps 16 and 17). That is, the process of step 6-2 corresponds to the abnormality determination process, and steps 16 and 17 correspond to the abnormality occurrence response process.

  In the heating cooker that executes the control as described above, the object to be heated is placed on Gotoku 6, and then the standard burner 1a is ignited to perform cooking by heating. After cooking, the standard burner 1a is extinguished and then heated. When used in a usage pattern in which an object is moved to another place, as shown in FIG. 8, the set delay time after the fire extinguishing is commanded by each of the point fire extinguishing switches 32 and 61 and the power-off condition is satisfied. Until the time elapses, the placement state detection unit D detects a state where there is no heating target by moving the heated object to another place, and the integrated value Tk of the loading state duration time is reset to zero. Are repeatedly performed, so that the abnormality countermeasure process and the abnormality occurrence process are avoided.

  On the other hand, the state where the object to be heated is detected is detected without detecting the temperature rapidly decreasing state, even though the object to be heated is not placed in Gotoku 6 due to the failure of the placement state detection unit D or the like. When an abnormality has occurred, as shown in FIG. 9, even if the set delay time elapses after the fire extinguishing is commanded by the point fire extinguishing switches 32 and 61 and the power-off condition is satisfied, the mounted state Since the detection unit D does not detect the state where there is no object to be heated, the integration of the integrated value Tk of the mounting state duration time is continuously performed.

  Then, as shown in FIG. 10, the temperature is maintained in a state in which the state in which the object to be heated is detected is maintained until the set delay time elapses after it is determined that the power-off condition is satisfied. When the temperature suddenly decreasing state is detected in the determination process, in this case, it is assumed that the mounting state detection unit D is in the mounting state and is in a failure state, and therefore the abnormality occurrence count. The counter value Nk is counted up, the count value is written in the nonvolatile memory Me, the intermittent switching circuit 41 is switched to the cutoff state, and the power is turned off (steps 11-3, 11-4, 12, 13). ).

  In the above description, the control in the standard burner 1a has been described. However, the operation control unit H performs the same control for the high thermal power burner 1c.

As shown in FIG. 11, when the placement state detection unit D detects that the device is in the non-placed state after the start of power supply until the power-off condition is satisfied, the sticking determination is performed. After resetting the count value Nk of the counter for counter to zero and resetting the integrated value Tk for the above-mentioned set state duration to zero (steps 5-1 and 5-2), all the fire extinguishing switches 32 and 61 are turned off. The combustion control similar to the combustion control in the first embodiment is executed while maintaining the power-on state until the power-off condition is satisfied until the power-off condition is satisfied (steps 18, 19, 20). Then, the reset integrated value is written in the nonvolatile memory Me, and the power supply is shut off (steps 12 and 13).

  By executing the control in this way, the mounting state detection unit D can perform the non-mounting state even once from the start of power supply to the operation control unit H until the power-off condition is satisfied. If it is detected, the supply of power is cut off. In addition, during the period from when the integrated value is reset to when the power supply is cut off, even if the mounting state detection unit D may detect the previous mounting state, the previous mounting state duration is not integrated. It will be.

If the power-off condition is satisfied when the power-off condition is detected, the supply of power to the heating control unit 100 is continued, and a set delay time elapses from when the power-off condition is satisfied. Or delay the setting When a predetermined power supply holding release condition during the period until time elapses is satisfied, and is configured to cut off the power supply to the heating control means 100.

  Explaining the specific configuration, the control when the power-on condition is satisfied and the power is supplied to the operation control unit H is the same as that in the first embodiment, but all the point-extinguishing switches are turned off. The control when it is determined that the power-off condition is satisfied is different from the first embodiment.

That is, the operation control unit H executes the following control.
As shown in FIG. 12, when it is determined that all the fire extinguishing switches 32 and 61 are turned off and the power-off condition is satisfied, the placement state detection unit D detects a state in which there is no object to be heated. And even if it is detected that the mounting state is detected by the mounting state detection unit D, the integrated value Tk of the mounting state duration time is then determined from the abnormality determination set time Ts (30 hours). If it is less than the setting time Th for changing the interruption condition set to a short time (for example, 20 hours), the integrated value Tk of the mounting state duration at that time is written in the nonvolatile memory Me, and the intermittent switching circuit 41 is set. Switching to the shut-off state and turning off the power (steps 31, 34, 36, 33). That is, the power supply to the heating control means 100 is cut off without continuing the power supply.

If the set time Th exceeds the set time Th, the power supply is continued and the mounting state detection unit D is not covered even if the set delay time (for example, 3 minutes) elapses after it is determined that the power-off condition is satisfied. When the state of detecting the presence of the heated object continues, the integrated value Tk of the mounting state duration at that time is written in the nonvolatile memory Me, and the intermittent switching circuit 41 is switched to the disconnected state to supply power. Is turned off (steps 34, 35-1, 36, 33). When the temperature determination process is performed until the set delay time elapses and the temperature suddenly falls, the count value Nk of the abnormality occurrence counter is counted up and the count value is stored in the nonvolatile memory Me. And the intermittent switching circuit 41 is switched to the cutoff state to turn off the power (steps 35-1, 35-2, 35-3, 35-4, 36, 33), which is the same as in the first embodiment.

The delay operation cancellation condition detected by the placement state detection unit D as being in the non-placement state from when power supply to the means 100 is started until the power-off condition is fulfilled is satisfied. And when the power-off condition is satisfied, and when the integrated value of the above-mentioned standing state duration is equal to or shorter than the set time for changing the cutoff condition set to a time shorter than the set time for abnormality determination When the power-off condition is satisfied, the supply of power to the heating control unit 100 is cut off, and the integrated value of the installation state duration exceeds the set time for changing the cut-off condition And said heating The power-off in a state where it is not detected by the placement state detection unit D from the start of power supply to the control means 100 until the power-off condition is satisfied. When the condition is satisfied, the supply of power to the heating control unit 100 is continued, and the set delay time elapses from when the power-off condition is satisfied, or the set delay time elapses. In the meantime, the power supply to the heating control means 100 is cut off when a predetermined power holding release condition is satisfied.

  A specific configuration will be described. When the power-on condition is satisfied, power is supplied to the operation control unit H, the previous installation state is detected by the previous installation state detection unit D, and the previous installation state duration time is integrated. The control during execution is the same as that in the third embodiment, but the placement state detection unit D performs the above-described operation until the power-off condition is satisfied after the power supply to the operation control unit H is started. Control when it is detected that it is in the non-mounting state is different from that of the third embodiment.

That is, the operation control unit H executes the following control.
As shown in FIG. 13, it is detected by the mounting state detection unit D that the power supply to the heating control unit 100 is started and the power-off condition is satisfied. Then, after resetting the count value Nk of the sticking determination counter to zero and resetting the integrated value Tk of the above-mentioned mounting state duration to zero (steps 5-1, 5-2), all points Until the fire extinguishing switches 32 and 61 are turned off and the power-off condition is satisfied, the combustion control similar to the combustion control in the first embodiment is executed while maintaining the power-on state (steps 18, 19, and 20). When the power-off condition is satisfied, the reset integrated value is written in the nonvolatile memory Me, and the power is shut off (steps 36 and 33).

  (D) In each of the above embodiments, the power supply control unit PK exemplifies that the set delay time is set to a preset fixed time regardless of the length of the integrated value of the mounting state duration. Not limited to such a configuration, the power control means PK is configured to change and set the set delay time in a form in which the integrated value of the set state duration is longer when the integrated value of the installed state duration is longer than when it is shorter. You may do it.

  For example, the set delay time is 3 minutes while the integrated value of the above-mentioned standing state duration is short, but the set delay time is lengthened as the integrated value of the above-mentioned standing state duration becomes long, and the maximum is about 10 minutes. The setting delay time may be changed and set so as to be gradually increased, or the setting delay time may be changed and set so as to be gradually increased. In addition, if the integrated value of the above-described standing state continuation time is equal to or less than the set time for changing the cutoff condition set to a time shorter than the above-described abnormality determination setting time, the set delay time is set to zero, and the above-described standing state continuation is set. When the integrated value of the time exceeds the setting time for changing the cutoff condition, the setting delay time may be changed and set to a longer time as the integrated value of the above-described standing state duration becomes longer.

  (E) In each of the above embodiments, the power management means 101 that manages the power supply state using the operation control unit H is configured, and the power control means PK is configured by the power management means 101 and the intermittent switching circuit 41. However, instead of such a configuration, the power management unit 101 may be configured using another control device different from the operation control unit H configuring the heating control unit 100, The other control device may be configured to manage the intermittent switching circuit 41 based on information from the heating control means 100.

The power-off condition is satisfied when all of the plurality of heating command units are switched from the heating operation state to a full stop state in which a heating stop command is issued. In other words, the power-on condition is satisfied. However, a dedicated power switch for instructing the operation control unit H to turn on / off the power is provided, and the power-on condition is set by turning on the power switch. A configuration may be adopted in which it is assumed that the power-off condition is satisfied by turning off the power switch.

  (G) In each of the above-described embodiments, the placement state detection unit includes the vertical movable unit and the object to be heated detection switch.
