  By the way, it is preferable that the grill device be controlled so that the grill burner is ignited only when the closed state of the grill door is detected by the tray temperature sensor. This is because useless combustion of the grill burner when the grill door is open can be suppressed.

  However, the tray temperature sensor for detecting the open / closed state of the grill door may break down so as to maintain the state in which the closing of the grill door is detected. When the pan temperature sensor fails in this way, it is erroneously determined that the grill door is in a closed state, so the grill burner is ignited even though the grill door is not closed, and the grill burner is wasted. There is a possibility of burning.

  The present invention has been made in view of the above circumstances, and even when the open / close detection unit for detecting the open / close state of the grill door fails to maintain the state of detecting the close of the grill door, It is an object of the present invention to provide a grill device that can prevent heating by a section.

  The grill device of the present invention has the following first feature. A grill chamber that opens forward, a grill door that closes a front opening of the grill chamber so as to be openable and closable, a heating unit that heats the inside of the grill chamber, and a command to start and stop heating by the heating unit An operation unit; a control unit that starts and stops heating by the heating unit in response to a command by an operation of the operation unit; and an open / close detection unit that detects an open / closed state of the grill door. Only when the closed state of the grill door is detected by the open / close detection unit, the heating unit starts heating, and after the heating unit stops heating, the open / close detection unit performs the grilling. When a predetermined time elapses while maintaining the state in which the door is detected to be closed, heating by the heating unit is not executed even when there is a heating start command from the operation unit.

  Moreover, it is preferable that a grill apparatus has the 2nd characteristic shown below. The control unit maintains a state in which the grill door is detected to be closed by the opening / closing detection unit after the heating unit has stopped heating, and until the predetermined time has elapsed, a heating start command from the operation unit If the number of heating start commands by the operation unit, which has been performed from the time when the heating unit stops heating, exceeds a preset number of times, the heating unit starts heating. Do not execute.

  Moreover, it is preferable that a grill device has the 3rd characteristic shown below. A support for supporting the cooking container stored in the grill storage is provided, and the support is configured to move in the grill storage in conjunction with opening and closing of the grill door. A container detection unit is provided for detecting the cooking container supported by the support when the grill door is closed, and the container detection unit constitutes the open / close detection unit.

  In the grill device having the first feature of the present invention, after the heating by the heating unit is stopped, the opening / closing detection unit maintains the state in which the closing of the grill door is detected, and when the predetermined time has elapsed, the operation of the operation unit Even if there is a command to start heating by the heating unit, heating by the heating unit is not started. For this reason, when a failure occurs so that the opening / closing detection unit maintains the state of detecting the closing of the grill door, useless heating by the heating unit can be suppressed while the grill door is open.

  In addition, the grill device having the second feature is configured to perform heating according to the heating command when the number of heating start commands by the operation unit, which is performed after the heating unit stops heating, exceeds a predetermined number of times set in advance. Do not start heating by the part. Here, when the predetermined number of times is exceeded, there is a high probability that the open / close detection unit has failed so as to maintain the state of detecting the closing of the grill door. For this reason, when the open / close detection unit fails, it is possible to further suppress unnecessary heating by the heating unit in a state where the grill door is open.

  In addition, the grill device having the third feature can suppress unnecessary heating by the heating unit when the cooking container is not detected by the container detection unit. Moreover, when it breaks down so that the container detection part may maintain the state which detected the cooking container, it can suppress that the useless heating by a heating part is performed.

The container 25A, 25B is not detected without contacting the container detector 27A.

  Detection information (presence / absence of cooking containers 25A, 25B) by the container detection unit 27A is output as a detection signal to the control unit 6 shown in FIG. In addition, although the container detection part 27A of this embodiment is a contact sensor, it may be a non-contact sensor.

  The control unit 6 determines that the grill door 26 is in the closed state when detecting at least one of the first cooking container 25A or the second cooking container 25B from the container detection unit 27A, and the first cooking container 25A and the second cooking container When none of 25B is detected, it is determined that the grill door 26 is in the open state. The detection by the container detection unit 27A and the determination of the open / closed state of the grill door 26 are performed constantly or intermittently.

  As shown in FIG. 1, an operation panel 45 is provided on the front surface of the casing 10. As shown in FIG. 8, the operation panel 45 is provided with an operation portion 46 for grill. The operation unit 46 includes a point fire extinguishing switch 47A, a menu changeover switch 47B, and a fire control switch 47C.

  The user can command ignition (start of heating) and extinguish (stop heating) of both burners 28A and 28B by operating the point fire switch 47A. When a command to ignite the grill burners 28A, 28B is issued, the control unit 6 sparks both the spark plugs 33A, 33B and puts the upper burner 28B and the lower burner 28A into an ignition state (that is, heating by the heating unit 21). Run start). As will be described later, the ignition of both the burners 28A and 28B is performed only when the grill door 26 is in the closed state.

  Further, when an instruction to extinguish the grill burners 28A, 28B is made by operating the point fire switch 47A, the control unit 6 closes both the shut-off valves 37A, 37B and extinguishes the upper burner 28B and the lower burner 28A (that is, The heating is stopped by the heating unit 21). When the control valve 6 closes both the shut-off valves 37A and 37B, the control unit 6 arranges the gas amount control plate 40 of the grill flow regulating valve 38 at the position shown in FIG. 6E, and the flow hole of the lower burner tip 39A. 43A to 43D and all the through holes 43A to 43D of the upper burner tip 39B are shielded by the gas amount control plate 40.

  In addition, the user can issue a command for automatic grill control by operating the menu changeover switch 47B shown in FIG. 8, and then operating the fire extinguishing switch 47A.

  Specifically, the user operates the menu changeover switch 47B to perform a plurality of cooking such as “fish: grilled”, “fish: fillet”, “hamburger”, “grilled chicken”, “toast”, “rice”, etc. Any cooking menu can be set from the menu.

  After the cooking menu is set, the user operates the fire adjustment switch 47C to set the cooking finish (heating temperature) in the set cooking menu to any level from “high”, “medium”, and “low”. Can be set.

  In addition, the user can instruct the start of automatic grill control based on the set cooking menu and cooking finish by operating the fire extinguishing switch 47A after setting the cooking menu and cooking finish. If the point fire switch 47A is operated without the point fire switch 47A being operated after the user operates the menu switch 47B, the cooking finish is set to “low”. An automatic grill control command is issued.

  As described above, when a command for automatic grill control is issued by operating the operation unit 46, the control unit 6 starts automatic grill control shown below.

  When the automatic grill control command is issued, the control unit 6 sparks both the spark plugs 33A and 33B to ignite the lower burner 28A and the upper burner 28B, and then sets the cooking menu and the cooking finish. Based on the above, the heating power of the lower burner 28A and the upper burner 28B is adjusted to execute a predetermined cooking process set for each cooking menu, and then the lower burner 28A and the upper burner 28B are extinguished. As will be described later, the automatic grill control is also performed only when it is determined that the grill door 26 is in the closed state.

  Here, only when the controller 6 determines that the grill door 26 is in the closed state based on the detection result by the container detector 27A, the ignition of the grill burners 28A and 28B according to the operation of the operation unit 46 is performed. (Including ignition during automatic grill control) is allowed, and in other cases (that is, when it is determined that the grill door 26 is in the open state), the grill burners 28A and 28B are operated by operating the operation unit 46. Even if there is an ignition command, the grill burners 28A and 28B are not ignited. Thus, the lower burner 28A and the upper burner 28B are ignited only when the grill door 26 is in the closed state, and the lower burner 28A and the upper burner 28B are burned wastefully when the grill door 26 is in the open state. It becomes difficult to be done.

  Moreover, the control part 6 maintains the state which the container detection part 27A detected the 1st cooking container 25A or the 2nd cooking container 25B from the fire extinguishing of the grill burners 28A and 28B, and the preset predetermined time passes. In the meantime, it is determined that there is a temporary failure state, and from the extinction of the grill burners 28A, 28B, the container detection unit 27A maintains the state where the first cooking container 25A or the second cooking container 25B is detected, When the predetermined time has elapsed, it is determined that the container detector 27A has failed ON.

  Here, the ON failure means that the container detection unit 27A maintains a state in which at least one of the first cooking container 25A or the second cooking container 25B is detected (that is, a state in which the closing of the grill door 26 is detected). Means that The predetermined time may be a time when it is estimated that the container detection unit 27A has an ON failure, and is appropriately determined according to the usability of the grill device, the expected usage method, the usage environment, and the like. Specifically, in the present embodiment, the predetermined time is set to 24 hours.

Further, the control unit 6 starts from the time when the grill burners 28A and 28B are extinguished.
Until the predetermined time elapses while maintaining the state where the container detection unit 27A detects the first cooking container 25A or the second cooking container 25B (that is, when it is determined to be a temporary failure state), The number of times the ignition of the grill burners 28A and 28B is commanded according to the operation of the operation unit 46 is counted. Then, when the control unit 6 determines that the temporary failure state has occurred, when there is an ignition command from the operation unit, the grille burners 28A and 28B are immediately extinguished from the time when the operation unit 46 Even when the cumulative value of the number of times the grill burners 28A and 28B are commanded in accordance with the operation exceeds a predetermined number set in advance, it is determined that the container detection unit 27A has failed. Here, the predetermined number of times may be the number of times that it is estimated that the container detection unit 27A is in failure, and is appropriately determined according to the usability of the grill device, the expected usage method, the usage environment, and the like. It is. Specifically, in the present embodiment, the predetermined number of times is set to five.

  When the controller 6 determines that the container detector 27A has failed as described above, the controller 6 does not ignite the grill burners 28A and 28B thereafter.

  Specifically, the control unit 6 maintains the state where the container detection unit 27A has detected the first cooking container 25A or the second cooking container 25B from the extinguishing of both the grill burners 28A and 28B until 24 hours elapses. When the opening state of the grill door 26 is not detected in the meantime, the grill burners 28A and 28B are not ignited even if the ignition command for the grill burners 28A and 28B is issued by the operation of the operation unit 46 thereafter.

  Further, the control unit 6 maintains the state where the container detection unit 27A detects the first cooking container 25A or the second cooking container 25B from the extinguishing of both the grill burners 28A and 28B until 24 hours elapses. When the grill burners 28A and 28B are instructed to be ignited, if the number of times the grill burners 28A and 28B are instructed to be fired from the extinguishing of both the grill burners 28A and 28B is six times or more, the grill burner 28A , 28B is not ignited. The control unit 6 maintains the state where the container detection unit 27A detects the first cooking container 25A or the second cooking container 25B from the extinction of the grill burners 28A and 28B until 24 hours elapses. When the number of times the ignition of the grill burners 28A and 28B is commanded in accordance with the operation of the operation unit 46 is 5 times or less, the grill burners 28A and 28B are ignited in accordance with the operation of the operation unit 46.

  Thus, by igniting the ignition of the grill burners 28A and 28B when it is determined that the container detection unit 27A has failed to turn ON, the grill burners 28A and 28B are burned unnecessarily when the container detection unit 27A fails to turn ON. It is suppressed.

  Moreover, the grill part 2 of this embodiment is provided with the alerting | reporting part 48 for alerting | reporting to a user based on the detection result detected by the container detection part 27A. The notification unit 48 is electrically connected to the control unit 6. Note that the notification by the notification unit 48 is performed by sound, display, or a combination thereof.

  Specifically, when the control unit 6 determines that the container detection unit 27A has an ON failure as described above, the notification unit 48 notifies the user that the container detection unit 27A is in a failure state. Thus, the user can easily recognize that the container detection unit 27A has failed.

  The grill device of the present embodiment described above has the first feature described below. The grill device includes a grill cabinet 20 that opens forward, a grill door 26 that closes the front opening of the grill cabinet 20 so as to be openable and closable, a heating unit 21 that heats the inside of the grill cabinet 20, and heating by the heating unit 21. And an operation unit 46 for instructing a stop, a control unit 6 for starting and stopping heating by the heating unit 21 in response to a command by an operation of the operation unit 46, and an open / close detection for detecting an open / closed state of the grill door 26 Part 27. The control unit 6 starts heating by the heating unit 21 only when the open / close detection unit 27 detects the closed state of the grill door 26. In addition, after the heating by the heating unit 21 is stopped, the control unit 6 starts heating by the operation unit 46 when a predetermined time elapses while maintaining the state where the opening / closing detection unit 27 detects the closing of the grill door 26. The heating unit 21 does not start heating even if there is a command.

  In the grill device having the first feature, when the opening / closing detection unit 27 does not detect the closed state of the grill door 26, the heating unit 21 starts heating even when the operation unit 46 gives a heating start command. Do not execute. For this reason, it can suppress that the useless heating by the heating part 21 is performed when the grill door 26 is open.

  In addition, after the heating unit 21 stops heating, when the predetermined time has elapsed after the opening / closing detection unit 27 detects the closing of the grill door 26, the heating unit 21 starts heating by operating the operation unit 46. The heating unit 21 does not start heating even if there is a command. For this reason, when the open / close detection unit 27 is in an ON failure, it is possible to prevent the heating unit 21 from performing unnecessary heating while the grill door 26 is open.

  Moreover, it is preferable that a grill device has the 2nd characteristic shown below like this embodiment. The control unit 6 is instructed to start heating by the operation unit 46 from the time when the heating unit 21 stops heating until the opening / closing detection unit 27 detects the closing of the grill door 26 until a predetermined time elapses. When the heating unit 21 stops heating, the heating unit 21 starts heating when the number of heating start commands by the operation unit 46 exceeds a predetermined number of times set in advance. Do not execute.

  The grill device having the second feature is provided with a heating command when the number of heating start commands performed by the operation unit 46 after the heating unit 21 stops heating exceeds a predetermined number of times set in advance. The start of heating by the corresponding heating unit 21 is not executed. Here, when the predetermined number of times is exceeded, it can be said that there is a high probability that the open / close detection unit 27 is ON-failed. For this reason, when the open / close detection unit 27 is in an ON failure, it is possible to further suppress unnecessary heating by the heating unit 21 in a state where the grill door 26 is opened.

  Moreover, it is preferable that a grill device has the 3rd characteristic shown below like this embodiment. The grill device includes a support 23 for supporting the cooking containers 25A and 25B housed in the grill cabinet 20. The support 23 is configured to move in the grill cabinet 20 in conjunction with opening and closing of the grill door 26. The grill storage 20 is provided with a container detector 27A for detecting the cooking containers 25A and 25B supported by the support 23 when the grill door 26 is closed. The container detector 27A constitutes the open / close detector 27.

  The grill device having the third feature can suppress unnecessary heating by the heating unit 21 when the container detection unit 27A does not detect the cooking containers 25A and 25B. In addition, when the container detection unit 27A has an ON failure, it is possible to suppress unnecessary heating by the heating unit 21.

  The opening / closing detection unit 27 is not limited to the container detection unit 27A, and may be, for example, a sensor that detects the open / closed state of the grill door 26 by contacting the closed grill door 26. The heating unit 21 is not limited to the grill burners 28A and 28B, and may be an electric heater, an induction heater, or the like. In addition, the design of the grill device of the present embodiment can be changed as appropriate without departing from the spirit of the present invention.
