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. The mounting state detecting means to detect and the mounting state duration time in which the previous mounting state is continuously detected by the previous mounting state detection means are integrated, and the integrated value of the mounting state duration time is used for abnormality determination. An abnormality countermeasure control means for executing abnormality countermeasure processing when a set time is reached, and when the power-on condition is satisfied by an operation command of the manual operation means, power is supplied to the abnormality countermeasure control means, and the operation of the manual operation means is performed. The present invention relates to a heating cooker configured to include power supply control means for cutting off power supply to the abnormality countermeasure control means when a power-off condition is satisfied by a command.

  The heating cooker is safe in use, such as detecting the placement state and non-placement state of the object to be heated by the placement state detection means, and changing the heating state of the heating means according to the result. In addition, an abnormality in which the above-described placement state is detected even though the object to be heated is not placed on the placement portion due to a failure of the placement state detection means, etc. In such a heating cooker, conventionally, it has been configured as follows. was there.

  That is, as the setting time for abnormality determination, a time (for example, 96 hours) in which a state in which the object to be heated is continuously placed on the placement portion can hardly occur in a general use state is set. When the power-on condition is satisfied by turning on the power switch as the manual operation means, power is supplied to the control means, and when the power-off condition is satisfied by turning off the power switch, the placement state detecting means is not turned on. If the mounting state is detected, the power supply to the abnormality countermeasure control unit is stopped, and if the mounting state detection unit detects the mounting state when the power-off condition is satisfied, an abnormality is detected. An error occurs when the power supply to the countermeasure control means is continued and the mounting state duration time is continuously accumulated (hereinafter referred to as the former configuration in the following description) and when the power-off condition is satisfied. Countermeasure control The power supply to the stage is stopped to interrupt the integration of the mounting state duration and the integrated value is stored in the non-volatile memory. Next, when the power-on condition is satisfied, the mounting state detecting means loads the integrated value. When the mounting state is detected, there is a configuration in which the integration of the mounting state duration is resumed in a state of adding to the integrated value stored in the nonvolatile memory (hereinafter referred to as the latter configuration). (For example, see Patent Document 1).

  As the abnormality countermeasure process, for example, guidance information that prompts the user to raise the object to be heated from the placement unit is notified by a notification unit such as a speaker, and a set time elapses after the notification of the guidance information is started. If the mounting state detection means detects a non-mounting state until the set time elapses after resetting the integrated value of the mounting state duration and ending the abnormality countermeasure processing and starting the notification of guidance information Even if the placement state detection means does not detect the non-placement state, it is determined that an abnormality has occurred, and processing for the abnormality is performed.

JP 2006-97976 A

  In the former configuration of the above-described conventional configurations, when the mounting state detection unit detects the mounting state when the power-off condition is satisfied by the operation command of the manual operation unit, If no abnormality has occurred by continuing the power supply, the user then lifts the object to be heated from the placing part or moves it to another place. When the non-mounting state is detected by the mounting state detecting means, the integrated value of the mounting state duration time is reset, so that it is unnecessary even though no abnormality has occurred. Abnormality countermeasure processing is not performed.

  When the explanation is added, the following usage forms are generally considered as usage forms in this type of cooking device. That is, after the user places the object to be heated on the placement unit, the user performs an operation command of the manual operation means for satisfying the power-on condition so as to start cooking. During execution of the cooking, the user often performs the work of changing the placement state of the object to be heated as described above, and when the cooking is completed, the user manually operates to satisfy the power-off condition. It is considered that there are many cases in which the operation state of the object to be heated is performed immediately after the operation command of the operation means is performed and the cooked material is taken out immediately after that. However, depending on the user, there is a case where the operation for changing the placement state of the object to be heated is not performed during cooking.

  Therefore, in the former configuration of the above-described conventional configurations, even when the mounting state detection unit detects the mounting state when the power-off condition is satisfied, power is supplied to the abnormality countermeasure control unit. If the user performs an operation command of the manual operation means for satisfying the power-off condition to stop the cooking, and then performs the above-described heating object placement state change operation Then, the non-placed state is detected by the placed state detecting means, and the integrated value of the placed state duration time is reset. Therefore, there is little possibility that the abnormality countermeasure process is unnecessarily performed even though no abnormality has occurred.

  However, as a usage pattern of the cooking device, it may be used in a usage pattern different from the general usage pattern as described above. For example, after the cooking is finished and the operation command of the manual operation means for satisfying the power-off condition is satisfied to stop the cooking, the user does not perform the placing state changing operation of the object to be heated. Although there is a usage pattern in which the object to be heated is left unattended, in such a usage pattern, after the power-off condition is satisfied, the mounting state duration time is continuously accumulated and the abnormality countermeasure control means is reached. The power supply may continue for a long time.

  As a result, in the former configuration of the above-described conventional configuration, depending on the usage pattern by the user of the heating cooker, when the power-off condition is satisfied, the previous placement state is detected by the previous placement state detection means In addition, the power supply state to the abnormality countermeasure control means may continue for a long time, and there is a disadvantage that the power consumption in the abnormality countermeasure control means increases. In particular, a battery equipped with a battery as a power source is inconvenient because the battery is consumed in a short time and the replacement time is shortened.

  On the other hand, in the latter configuration of the above-described conventional configurations, power consumption is suppressed because power supply to the abnormality countermeasure control means is stopped when the power-off condition is satisfied, but in this configuration, as described above, Although there is no abnormality, there is a disadvantage that the above-described abnormality countermeasure processing may be performed periodically with the use of the cooking device.

  In other words, when the user performs the above-described operation for changing the placement state of the object to be heated during the cooking, the placement state detection means detects the non-placement state. Therefore, the integrated value of the mounting state duration time is reset, so that the abnormality countermeasure process is not performed unless an abnormality has occurred. However, there is a case where the user does not perform the above-described work for changing the placement state of the object to be heated when power is supplied to the abnormality countermeasure control unit and the cooking is performed. In such a usage mode, since the mounting state detection unit does not detect the non-mounting state while power is supplied to the abnormality countermeasure control unit, the integrated value of the mounting state duration time described above Will continue to accumulate without being reset.

  As a result, in the latter configuration of the above-described conventional configuration, depending on the usage by the user of the heating cooker, the setting state duration time is set for abnormality determination even though the setting state detection means is not abnormal. There is a disadvantage in that it takes time to execute unnecessary abnormality countermeasure processing.

  In particular, as a manual operation means for satisfying the power-on condition and the power-off condition, in place of the power switch, heating to the heating means is performed using a heating command operation unit that commands execution and stop of heating to the heating means. In the configuration in which the power-on condition is satisfied when the heating is started and the power-off condition is satisfied when the heating is stopped, an unnecessary abnormality countermeasure process is executed even though the mounting state detecting means is not abnormal. The fear was great.

  An object of the present invention is to enable heating to be able to suppress power consumption but prevent unnecessary abnormality countermeasure processing from being performed even though no abnormality has occurred. The point is to provide a cooker.

1st characteristic structure of this invention is the mounting state in which the to-be-heated material is mounted in the mounting part which mounts the to-be-heated material heated with a heating means, or the non-mounting which is not mounted A mounting state detecting means for detecting whether or not the state;
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. An abnormality countermeasure control means to be executed;
When the power-on condition is satisfied by the operation command of the manual operation means, power is supplied to the abnormality countermeasure control means, and when the power-off condition is satisfied by the operation command of the manual operation means, the power to the abnormality countermeasure control means A heating cooker configured to include power supply control means for cutting off the supply of
The abnormality countermeasure control means is
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 the power-off condition is satisfied when it is detected that the non-placed state is detected by the placement state detection means, and the integrated value of the placement state duration is set for the abnormality determination If the power-off condition is satisfied when the power-off condition is not more than the set time for changing the cut-off condition set to a time shorter than the time, the power supply to the abnormality countermeasure control means is cut off, and
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 abnormality countermeasure control means, until the set delay time elapses from when the power-off condition is satisfied, or until the set delay time elapses In the meantime, when it is detected by the placement state detection means that the non-placement state, the supply of power to the abnormality countermeasure control means is cut off.

According to the first characteristic configuration, the abnormality countermeasure control means detects the placement state in which the object to be heated is placed on the placement portion by the placement state detection means when power is supplied. Then, the mounting state duration time in which the mounting state is continuously detected is integrated. In addition, when the non-mounting 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 integrated value of the placement state duration time is reset. .

  Then, the power control means supplies power to the abnormality countermeasure control means when the power-on condition is satisfied by the operation command of the manual operation means, but when the power supply to the abnormality countermeasure control means is cut off, the power-off condition is The timing for cutting off the power supply differs depending on the detection result of the mounting state detection means when it is satisfied.

  In other words, if the power-off condition is satisfied by the operation command of the manual operation means when the placement state detection means detects that it is in the non-placement state, the placement state detection means in this way When 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 abnormality countermeasure control unit is cut off. It is.

  On the other hand, if 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 abnormality countermeasure control means is satisfied. 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 the power supply is not supplied to the abnormality countermeasure control means, the set delay time elapses from when the power-off condition is satisfied or until the set delay time elapses. When it is detected by the state detection means that it is not placed, the supply of power to the abnormality countermeasure control means 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. When is satisfied, the supply of power to the abnormality countermeasure 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 power-off condition is satisfied, the power consumption is suppressed as much as possible by cutting off the power supply to the abnormality countermeasure control means.

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 form of use of the cooking device, the user places an object to be heated in order to perform an operation command for manual operation means to finish the cooking and satisfy the power-off condition, and to take out the cooked food immediately after that. If it is used in a usage pattern that performs a work of changing the placement state of the object to be heated that is lifted from the mounting part or moved to another place, the object to be heated is until the set delay time elapses. When the mounting state changing operation is performed, it is detected by the mounting state detection means that the device is in the non-mounting state.
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 It will be set to about 10 minutes.

Then, when it is detected by the placement state detection means until the set delay time elapses, the integrated value of the placement state continuation time is reset to the abnormality countermeasure control means. The power supply will be cut off. As a result, it is possible to avoid executing unnecessary abnormality countermeasure processing even though no abnormality has occurred 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 performing the operation command of the manual operation means for satisfying the power-off condition, using that, When no abnormality has occurred, the integrated value of the mounting state duration is reset by the user's operation.
On the other hand, if the set delay time elapses without being detected by the placement state detection means to be in the non-placement state, the power to the abnormality countermeasure control means is not reset without resetting the integrated value of the placement state duration time. The supply is cut off, but at this time, it is possible that an abnormality has occurred, such as a failure of the mounting state detection means, so the integrated value of the mounting state duration is kept as it is, and the next power When the supply is started, the mounting state duration time is integrated by adding to the integrated value.

  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 abnormality countermeasure control is performed for a long time. Since the supply of power to the 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. 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 value is accumulated until the abnormality determination set time is reached, and abnormality countermeasure processing is executed.

Therefore, according to the first feature configuration, while it is possible to suppress power consumption, it is possible to prevent the abnormality countermeasure processing from being performed unnecessarily even though no abnormality has occurred. It came to be able to provide the cooking device which became possible.

The second characteristic configuration of the present invention, in addition to the first feature configuration, the abnormality countermeasure control means, and said non-placed state is detected by said placing state detecting means when the power is being supplied When the integrated value is reset, until the power supply is cut off after the integrated value is reset, the installation state may be detected by the installation state detection means. The point is that the state duration time is not accumulated.

According to the second characteristic configuration, the abnormality countermeasure control unit resets the integrated value of the mounting state duration when the mounting state detection unit detects a non-mounting state when power is supplied. However, the state in which the non-mounting state is detected by the mounting state detecting unit is considered to be a state in which the mounting state detecting unit is operating normally. In other words, the above-described setting state duration integration process for detecting an abnormality in the setting state detecting means is not executed.
In this way, when it is considered that the mounting state detecting means is in a normally operating state, the integration processing of the mounting state duration time is not performed, so that the previous integrated value is unnecessarily integrated. It is easy to avoid the abnormal countermeasure processing being performed unnecessarily.

In the third feature configuration of the present invention, in addition to the first feature configuration or the second feature configuration, the power supply control unit is configured to be longer when the integrated value of the set state duration is longer than when the integrated value is shorter. The configuration is such that the set delay time is changed and set.

According to the third characteristic configuration, since the setting delay time is changed and set to be longer when the integrated value of the standing state duration time is longer than when the accumulated value of the standing state duration time is short, the integrated value of the previous standing state duration time 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 a fourth feature configuration of the present invention, in addition to any one of the first feature configuration to the third feature configuration, the abnormality countermeasure control means is configured such that the integrated value of the set state duration is the abnormality as the abnormality countermeasure processing. When the set time for determination is reached, a notification process for notifying the guide information for urging the object to be lifted from the placement unit by the notification means is executed, and the elapsed time from the start of the notification process When it is detected by the above-mentioned installation state detection means that the above-mentioned installation state is detected even after the notification set time has elapsed, a heating operation check process for checking the heating operation by the heating means is executed. It is in the point which is comprised.

According to the fourth feature configuration, the abnormality countermeasure control means, as the abnormality countermeasure processing, when the integrated value of the placement state continuation time reaches the abnormality determination set time, the notification means removes the object to be heated from the placement section. Since the guide information that prompts the user to raise is notified, the user can recognize that an abnormality has occurred based on the guide information. Therefore, by urging the user to lift the object to be heated from the placement unit, the object to be heated is lifted from the placement unit or moved to another location.

  In addition, when it is detected that the above-described installation state is detected by the above-described installation state detection means even if the elapsed time since the start of the notification process has passed the notification set time, for example, the installation Since it is considered that an abnormality may have occurred, such as failure of the state detection means, in such a case, the abnormality countermeasure control means executes the heating operation check process, so that the user performs the heating operation. Even if the command is given, the heating operation by the heating means is restrained and the safety in use is improved.

In addition to any of the first feature configuration to the fourth feature configuration, the fifth feature configuration of the present invention is provided with a plurality of the heating means,
As the manual operation means, a plurality of heating command operation units for commanding execution and stop of heating for each of the plurality of heating means are provided,
The power control means is
When the heating operation state in which at least one of the plurality of heating command operation units commands the execution of heating is switched to the fully stopped state in which all of the plurality of heating command operation units command the heating stop, the power source It is configured that the power-on condition is satisfied when the switching condition is satisfied and when switching from the fully stopped state to the heating operation state.

According to the fifth characteristic configuration, a plurality of heating means for heating the object to be heated are provided in a state in which execution and stop of heating can be individually commanded by the heating command operation unit, and a plurality of heating means are provided as the manual operation means. A plurality of heating command operating sections are provided for commanding execution and stop of heating individually for each of the means.

  When the power supply control unit switches from a completely stopped state in which all the heating units have stopped heating to a heating operation state in which at least one of the plurality of heating command operation units commands execution of heating, It is assumed that the power-on condition is satisfied because it is necessary to supply power to the countermeasure control means. Further, when the power source control means switches 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 abnormality countermeasure control means.

  For example, in the case of providing a dedicated power on / off operation means for commanding the power off condition and the power on condition, etc., after commanding the heating stop command of the heating means, the operation by the power on / off operation means It is also possible to forget the operation to command the power off command, which may cause the power supply to the abnormality countermeasure control means to continue unexpectedly long, but command the execution and stop of heating of the heating means Since it is determined to satisfy the power-off condition and the power-on condition by effectively using the heating command operation unit provided for the power-off condition, the power-off condition is satisfied by instructing the heating stop of the heating means. There is an advantage that power consumption due to long-term supply of power to the abnormality countermeasure control means due to forgetting operation can be suppressed. 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.

The number of LED lamps 72 corresponding to the amount is turned on and displayed. The grill combustion display section 73 is composed of a single LED lamp 74. When the grill burner 2 is ignited, the combustion state is displayed by turning on the LED lamp 74.

  Then, as shown in FIG. 2, the operation control unit H is configured so that the standard burner 1 a, the small burner is based on the pulse signals generated by the rotary encoders 33 corresponding to the standard burner 1 a, the small burner 1 b, and the high thermal power burner 1 c. The operation of the flow rate control valve 18 for each of the standard burner 1a, the small burner 1b and the high thermal power burner 1c is controlled so as to adjust the fuel supply amount to the 1b and high thermal power burner 1c. That is, the operation control unit H determines the rotation operation direction and the rotation operation amount of the rotation operation unit 31 based on the pulse signal output from the rotary encoder 33, and determines the determined rotation operation direction and rotation operation amount. Correspondingly, the combustion amount of the standard burner 1a and the like is adjusted.

  Further, as shown in FIG. 2, a speaker 37 is provided as a notifying means for notifying various information by voice, and the operation control unit H is configured to notify the various information by the speaker 37. .

  In this stove, the mounting state duration time in which the previous mounting state is continuously detected by the previous mounting state detection unit D is integrated, and the integrated value of the mounting state duration time is set as the abnormality determination setting time. If the condition for turning on the power is satisfied by the operation command of the manual operation means, power is supplied to the abnormality countermeasure control means 100 and the operation of the manual operation means is performed. Power supply control means PK that cuts off the supply of power to the abnormality countermeasure control means 100 when the power-off condition is satisfied by the command is configured.

  The abnormality countermeasure control unit 100 is configured to hold the integrated value of the mounting state duration time even when power supply is cut off, and when the power is supplied, the mounting state detection unit D When the non-mounting state is detected, the integrated value is reset. When the power is supplied, the mounting state is detected by the mounting state detecting means. When the power-off condition is satisfied when the power-supply control means PK is detected by the placement state detection unit D to be in the non-placement state, an abnormality countermeasure is provided. When the power-off condition is satisfied when the power supply to the control unit 100 is cut off and the mounting state detection unit D detects that the mounting state is described above, the abnormality countermeasure control unit 100 Continue to supply power to It is detected by the mounting state detection unit D that the set delay time elapses after the power-off condition is satisfied or until the set delay time elapses. The power supply to the abnormality countermeasure control means 100 is cut off.

  By the way, as this set delay time, the time required to lift or move the object to be heated after the power-off condition is satisfied by the operation of the manual operation means so that the power consumption does not increase. For example, it is set to about several minutes to 10 minutes.

  Further, when the abnormality countermeasure control means 100, as the abnormality countermeasure processing, when the integrated value of the set state continuation time reaches the abnormality determination set time, the speaker 37 serving as a notification means removes the object to be heated from the five virtues. The placement state is detected by the placement state detection unit D even when the notification time for performing the notification process is executed and the elapsed time since the start of the notification process has passed the set time for notification. Is detected, it is configured to execute a heating operation check process for checking the heating operation by the standard burner 1 or the high thermal burner 1c as the heating means.

  A specific configuration will be described. As shown in FIG. 10, a total of four point-extinguishing switches including three point-extinguishing switches 32 for the respective burners 1a, 1b, 1c and one point-extinguishing switch 61 for the grill burner 2. 32 and 61 correspond to the manual operation means, and the abnormality countermeasure control means 100 is configured using the operation control unit H. That is, the operation control unit H integrates 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 the mounting state When the integrated value of the continuation time reaches the setting state for determining the mounting state continuation abnormality, the abnormality countermeasure process is executed.

  In addition, the operation control unit H is configured to hold the integrated value of the mounting state duration time even when the power supply is cut off, and when the power is supplied, the mounting state detection unit D When the non-mounting state is detected, the integrated value is reset, and the mounting state duration time is integrated. As shown in FIG. 10, a non-volatile memory Me is provided to hold the integrated value even when the supply of power is cut off, and the operation control unit H immediately before the supply of power is cut off. The integrated value is written and stored in the nonvolatile memory Me.

  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, i.e., three point fire-extinguishing switches 32 for each stove burner and one point fire-extinguishing switch 61 for the grill burner 2, is turned on, It is configured to switch from the cut-off state to the power supply state as being satisfied.

  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 when the operation control unit H is not in operation without being supplied with power, when any of the point fire extinguishing switches 32 and 61 is turned on, the switching transistor 42 is switched to a conductive state, and the operation control is performed. It becomes the structure switched to the state by which the electric power is supplied to the part H.

The operation information of each point fire extinguishing switch 32, 61 is also input to the operation control unit H, and the operation control unit H performs switching until all of the four point fire extinguishing switches 32, 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. In other words, when all of the four point fire extinguishing switches 32 and 61 are turned off, the operation control unit H stops outputting the power holding signal because the power-off condition is satisfied.
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 point fire switch 32 corresponding to at least one of the standard burner 1a, the small burner 1b, the high thermal power burner 1c and the grill burner 2 is in the ON state. When all of the point fire extinguishing switches 32 corresponding to the 1a, the small burner 1b, the high thermal power burner 1c, and the grill burner 2 are in the OFF state, the valve is maintained in the closed state. A description of the control is omitted.

Hereinafter, based on the flowchart shown in FIG.11 and FIG.12, the control action of the said operation control part H is demonstrated.
When any one of the four point fire extinguishing switches 32 and 61 is turned on and power is supplied from the power source, the operation control unit H reads the stored contents of the nonvolatile memory Me and sends it to the intermittent switching circuit 41. A power holding signal for holding the power-on state 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 integrated value Tk of the mounting state duration time is reset to zero (steps 3, 4, and 5).

When the integrated value Tk of the above-described standing state duration has not reached the abnormality determination set time Ts, combustion control for the standard burner is executed (steps 6 and 7).
As shown in FIG. 12, in this combustion control, an ignition process for igniting the standard burner 1a is performed by opening the flow rate control valve 18 and applying a drive signal to the spark plug 7 to effect ignition (step 71, 72), by adjusting the opening degree of the flow rate control valve 18 so that the combustion amount corresponds to the thermal power at the stage corresponding to the pulse signal output from the rotary encoder 33, while adjusting the thermal power, the standard burner 1a Combustion is continued (step 73). If there is a fire extinguishing command, fire extinguishing processing is executed (step 74).

  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).

  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. The state is continued (step 78), and during that time, when the placement state detection unit D detects the state with the object to be heated, it returns to the original heating power and continues the combustion state, and the absence determination time has elapsed. 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 all the point fire extinguishing switches are turned off, it is determined that the power-off condition is satisfied. At that time, when the mounting state detection unit D of the standard burner detects the state where there is no object to be heated, the mounting is performed. The integrated value Tk of the state duration time is reset to zero, the reset value is written to the nonvolatile memory Me, and the output of the power holding signal for holding the power-on state output to the intermittent switching circuit 41 is stopped. Then, the operation to keep the power on is released, the intermittent switching circuit 41 is switched to the cutoff state, and the power is turned off (steps 8, 9, 10, 13).

  When it is determined that the power-off condition is satisfied, if the placement state detection unit D detects that there is an object to be heated, it continues to supply power and determines that the power-off condition is satisfied. If the mounting state detection unit D continues to detect the state with the object to be heated even after a set delay time (for example, 3 minutes) has elapsed, the mounting state duration time at that time continues. The integrated value Tk is written in 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, and the operation of holding the power-on state is canceled and the intermittent operation is performed. The switching circuit 41 is switched to the shut-off state to turn off the power (steps 11 and 12).

  When the integrated value Tk of the standing state duration time reaches the abnormality determination set time Ts, the guidance information that prompts the speaker 37 as a notification means to raise the object to be heated from the five virtues 6 such as “Please raise the pan”. And a notification operation for causing the front thermal power display unit 36 and the top thermal power display unit 71 corresponding to the standard burner 1a to blink in the same manner (step 14). When the placement state detection unit D detects the state with the object to be heated even if the elapsed time from the start of the notification has passed the notification set time Tm (for example, 48 hours), the speaker 37 is notified of failure information such as “A 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 flashed to notify that an abnormality has occurred. Alarm processing is executed (steps 15 and 16). And in this state, it will be in the state which does not receive operation by the command of the point fire switch 32 (step 17). The process of making the operation of step 17 unacceptable corresponds to the heating operation restraining 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 location, as shown in FIG. 13, the set delay time after 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. Is repeatedly performed, so that abnormality countermeasure processing is avoided.

  On the other hand, when an abnormality is detected in which the state of the heated object is detected despite the fact that the heated object is not placed in Gotoku 6 due to a failure or the like of the placement state detection unit D, FIG. As shown, even when 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 placement state detection unit D detects a state in which there is no object to be heated. Therefore, the integrated value Tk of the mounting state duration time is integrated and abnormality countermeasure processing is performed.

  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. That is, in this embodiment, the standard burner 1a and the high thermal power burner 1c correspond to the heating means.

Embodiment of the present invention
Next, the implementation form of the heating cooker according to the present invention.
The implementation form of this, other configuration of the power supply control unit PK is different, since it is same as that of the embodiment described above of reference, the description for only the description, the same configuration for different configurations will be omitted.

  That is, in this embodiment, when the power-off condition is satisfied when the power-supply control unit PK is detected by the placement state detection unit D to be in the non-placement state, and When the power-off condition is satisfied when the integrated value Tk of the stationary state duration time is equal to or shorter than the cutoff condition change setting time Th set to a time shorter than the abnormality determination setting time Ts, If the supply of power to the abnormality countermeasure control means 100 is cut off and the integrated value Tk of the above-mentioned placement state duration exceeds the cut-off condition change setting time Th, the above-mentioned placement state detection unit D When the power-off condition is satisfied when it is detected that the above-mentioned installation state is detected, the power supply to the abnormality countermeasure control unit 100 is continued to satisfy the power-off condition. Delay time set from time If it is detected that the non-placed state is detected by the placement state detection unit D before the set delay time elapses, supply of power to the abnormality countermeasure control means 100 Is configured to shut off.

The specific configuration will be described. 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 of the reference embodiment, but all the fire extinguishing switches are turned off. The control when it is determined that the power-off condition is satisfied is different from the reference embodiment.

That is, the operation control unit H executes the following control.
As shown in FIG. 15 , 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. Even when it is detected by the previous placement state detection unit D that the previous placement state is detected, the integrated value Tk of the previous placement state duration is then calculated as the abnormality determination set time Ts (30 hours). ) Is shorter than the set time Th for interruption condition change set to a shorter 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 switched off and the power is turned off (steps 34, 36, 33). That is, the power supply to the abnormality countermeasure control means 100 is cut off without continuing the power supply.

  Then, when it is determined that the power-off condition is satisfied, the placement state detection unit D detects the state with the object to be heated, and at that time, the integrated value Tk of the previous placement state duration is changed to the cutoff condition. 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, 36, 33).

Although illustrated, the power supply control means PK is not limited to such a configuration, and the set delay time is changed in a form in which the power supply control means PK is set to be longer when the integrated value of the mounting state duration is longer than when it is shorter. It may be configured to be set.
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 above set delay time is set to zero, 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.

  In such a manually operated stove, when the abnormality countermeasure process is executed, the placement state detection unit D detects a state with an object to be heated even if the elapsed time from the start of notification has elapsed. Even in this state, if the instrument plug is operated thereafter, the burner can be ignited. In such a configuration, after the burner is ignited, a set time (for example, 5 seconds) ) May be configured to notify the abnormality with a buzzer every time and to stop the combustion of the burner after a set time (for example, 1 minute) has elapsed.

  (E) In each of the above-described embodiments, the placement state detection unit D includes the vertically movable portion 9b and the heated object detection switch 10. However, for example, on both lateral sides of the vertically movable portion 9b, When the vertically movable portion 9b is pushed down, the magnet and the reed switch are located between the magnet and the reed switch, and when the vertically movable portion 9b returns upward, the magnet and the reed switch It is possible to configure with a magnetic body attached to the up and down movable part 9b so as to leave the space.

Photointerrupter configured to detect whether the object to be heated is placed or not to be placed based on whether the projection light is blocked by the presence of the sensor or the object to be heated on the placement unit It is possible to configure with a type of optical sensor.

  (F) The specific configuration of the notification means is not limited to the speaker 37 exemplified in the above embodiment. For example, it may be configured by a display device that displays the guidance information, a buzzer, a lamp, or the like. Alternatively, a plurality of speakers, display devices, buzzers, and lamps may be used.
