A temperature detection unit provided inside the grill and having a temperature sensor that abuts on the bottom of the cooking container attached to the drawer located at the storage position to detect the temperature of the cooking container.
An elevating support means provided in the grill chamber to support the temperature detection unit, the temperature detection unit is raised to bring the temperature sensor into contact with the bottom of the cooking container, and the temperature detection. An elevating support means configured so that the temperature sensor can be switched to a separated state separated from the bottom of the cooking container by lowering the portion.
When the drawer portion is located closer to the storage position than the predetermined position close to the storage position, the contact state is reached, and when the drawer portion is located closer to the drawer position side than the predetermined position, the separation state is reached. A grill provided with a mechanical linking means for mechanically linking the elevating support means and the drawer portion so as to be.
The temperature detection unit is a support shaft that is anchored to the elevating support means and extends in the vertical direction, and supports the temperature sensor at the upper end portion and urges the temperature sensor upward, and the support shaft. It is provided with a temperature sensor drop detection unit that detects that the temperature sensor has moved downward relative to the support shaft.
When the start of heating by the heating means is issued by the heating start / stop command means, and the temperature sensor drop detection unit detects the downward movement of the temperature sensor with respect to the support shaft, the temperature sensor drops relative to the support shaft. When the operation control unit starts heating by the heating means and the temperature sensor drop detection unit does not detect the downward movement of the temperature sensor with respect to the support shaft, the operation control unit is operated by the heating means. It is characterized by being configured so that heating does not start.

In the grill of the present invention, the temperature sensor drop detection unit is

The grill can be preferably realized.

Further, by using a Hall element for the first magnetic sensor, it becomes possible to easily adjust the sensitivity of the temperature sensor drop detection unit, and the present invention can be further implemented.

Further, also when the temperature sensor drop detection unit is provided with a second magnet that moves together with the support shaft and a second magnetic sensor that moves together with the temperature sensor and detects the magnetic flux from the second magnet. The grill of the present invention can be preferably realized.

Further, by using a Hall element for the second magnetic sensor, it becomes possible to easily adjust the sensitivity of the temperature sensor drop detection unit, and the present invention can be further implemented.

Further, the "descent state duration", which is the time during which the temperature sensor descent detection unit continuously detects the downward movement of the temperature sensor relative to the support axis, is the relative downward direction of the temperature sensor with respect to the support axis. When the "set time for determining continuous descent state abnormality", which is the time when it is considered appropriate to estimate the failure of the device, is reached when the movement to is long and the descent state continues. In addition, by configuring the operation control unit to execute the abnormality countermeasure processing, the elevating support means and the mechanical linking means that support the temperature detection unit break down, and the temperature detection unit determines the temperature at the bottom of the cooking container. It is possible to prevent the cooking from being continued in a state where it cannot be detected correctly, and to avoid the failure of the cooking.

In addition, when the "state in which the temperature sensor drop detection unit detects the relative downward movement of the temperature sensor with respect to the support axis" is canceled while the abnormality countermeasure processing is being executed (that is, the temperature sensor). When the descent detection unit no longer detects the downward movement of the temperature sensor relative to the support axis), the anomaly countermeasure process terminates the anomaly countermeasure process, for example, prohibiting combustion of the grill burner. If this is the case, or if it is to notify the information that something is wrong by means of notification using sound or light, the grill burner can be ignited and burned as usual, or the sound or light can be used. It becomes possible to end unnecessary notification by, and it becomes possible to provide a more convenient grill.

Since it is configured as described above, as the drawer portion 101 moves back and forth with respect to the grill storage 7, the operated body 217 included in the elevating support means X is operated by the operating body 117. When the temperature detection unit 130 moves up and down, the temperature sensor 13 included in the temperature detection unit 130 is in contact with the bottom Ka of the cooking container K, and the temperature sensor 13 is separated from the bottom Ka of the cooking container K. You can switch between states.

(About the temperature sensor drop detector)
Further, the grill G of this embodiment includes a temperature sensor drop detection unit Y for detecting that the temperature sensor 13 has moved downward relative to the support shaft 131.

Specifically, the temperature sensor drop detection unit Y is a magnetic sensor that moves together with the permanent magnet (first magnet) 141 that moves together with the temperature sensor 13 and the support shaft 131 described above to detect the magnetic flux from the first magnet 141. It is equipped with (first magnetic sensor) 142.

That is, in the grill G of the embodiment, the temperature sensor drop detection unit Y is configured by using the above-mentioned first magnet 141 and the first magnetic sensor 142, and the temperature sensor 13 refers to the support shaft 131. It is configured so that it can reliably detect that it has moved relatively downward.

Further, in this embodiment, the first magnetic sensor 142 is composed of a Hall element.

As shown in FIG. 6B, when the temperature sensor 13 moves downward relative to the support shaft 131, the first magnet 141 and the first magnetic sensor (Hall element) 142 are in a positional relationship facing each other. By detecting the magnetic field lines (magnetic flux) pointing from right to left by the first magnetic sensor 142, it is detected that the temperature sensor 13 has moved downward relative to the support shaft 131.

As described above, by using the Hall element as the magnetic sensor 142, the sensitivity of the temperature sensor drop detection unit Y can be easily adjusted by adjusting the constant of the detection circuit.

Then, in the grill G of this embodiment, the point fire extinguishing switch 48 (heating start / stop command means) provided in the grill setting operation unit 6 is operated to issue the start (ignition) of heating to the grill burner A. At this time, when the temperature sensor drop detection unit Y detects the downward movement of the temperature sensor 13 with respect to the support shaft 131, the operation control unit W ignites the grill burner A and starts heating, but the temperature sensor When the descent detection unit Y does not detect the downward movement of the temperature sensor 13 with respect to the support shaft 131, the grill burner A is not ignited and heating is not started.

Therefore, according to the grill G of the embodiment configured as described above, when the temperature sensor drop detection unit Y does not detect the relative downward movement of the temperature sensor 13 with respect to the support shaft 131, the elevating support means X By determining that the mechanical linking means 120 or the like is out of order, it becomes possible to reliably detect the failure of the parts related to the temperature detection such as the elevating support means X or the mechanical linking means 120, and also to cook. It becomes possible to detect that the temperature of the bottom Ka of the container K cannot be detected correctly.

That is, when the temperature sensor drop detection unit Y does not detect the relative downward movement of the temperature sensor 13 with respect to the support shaft 131, a failure of a portion related to temperature detection such as the elevating support means X or the mechanical linking means 120 occurs. By determining that is out of order, it is possible to reliably detect the failure of the elevating support means X, the mechanical linking means 120, and the like.

As a result, it is possible to prevent the cooking from being continued in a state where the mechanical linking means 120 and the elevating support means X are out of order (that is, the temperature of the bottom Ka of the cooking container K cannot be detected correctly), and the cooking fails. It can be avoided in advance.

Specifically, for example, as shown in FIG. 9, when the drawer portion 101 is in the retracted state, the temperature sensor 13 cooks even though the operated body 217 is in contact with the lower end of the contact operating body 117b. Prevents cooking from continuing in a state where it does not come into contact with the bottom Ka of the container K (that is, a state in which the mechanical linking means 120 or the elevating support means X has a failure), and avoids cooking failures. It becomes possible to do.

In the above embodiment, the temperature sensor drop detection unit Y moves with the first magnet 141 that moves together with the temperature sensor 13 and the support shaft 131 described above, and the first magnetic sensor that detects the magnetic flux from the first magnet 141. Although it was configured using 142, the temperature sensor drop detection unit Y moves together with the permanent magnet (second magnet) that moves with the support shaft 131 and the temperature sensor 13, contrary to the configuration shown in FIGS. 6A and 6B. However, it is also possible to have a configuration provided with a magnetic sensor (second magnetic sensor) that detects the magnetic flux from the second magnet.

Even with such a configuration, it is possible to easily and surely detect that the temperature sensor 13 has moved downward relative to the support shaft 131. Also in this configuration, it is preferable that the magnetic sensor (second magnetic sensor) is a Hall element, and in that case, the sensitivity of the temperature sensor drop detection unit Y is easily adjusted by adjusting the constant of the detection circuit. Will be possible.

[Another Embodiment 1]
Further, the grill of the present invention may further have a configuration as described below.
Since the basic configuration of the grill according to the alternative embodiment 1 is the same as that of the grill according to the above-described embodiment, only the configuration specific to the grill according to the alternative embodiment 1 will be described below. ..

That is, in the grill according to the other embodiment 1, it is the time during which the temperature sensor descent detection unit Y continuously detects the downward movement of the temperature sensor 13 with respect to the lower support shaft 131a. It is configured to measure the state duration Tk.

Then, when this "descent state continuation time Tk" reaches the "set time Ti for determining the descent state continuation abnormality", which is a preset predetermined time, the operation control unit W executes the abnormality countermeasure processing. It is configured.

The "set time Ti for determining the continuous abnormality of the descent state" is usually a time during which it is considered that the relative downward movement of the temperature sensor 13 with respect to the lower support shaft 131a is not continuously detected. It is set. Specifically, in the other embodiment 1, the "set time Ti for determining the continuous abnormality of the descent state" is set to 96 hours.

Generally, it is considered that the cycle of life is switched in 24 hours (one day), and the downward movement of the temperature sensor 13 relative to the lower support shaft 131a is not detected. That is, normally, it is considered that the cooking container K may be taken out from the grill storage 7 by the time when 24 hours have passed. On the other hand, by setting the "set time Ti for determining the continuous abnormality of the descent state" to, for example, about 96 hours, the lower support shaft of the temperature sensor 13 is usually set as the "set time Ti for determining the continuous abnormality of the descent state". A time is set in which a state in which a downward movement relative to 131a is detected is unlikely to occur.

That is, in this "set time Ti for determining the continuation abnormality of the descent state", the movement of the temperature sensor 13 downward relative to the lower support shaft 131a continues beyond the "set time Ti for determining the continuation abnormality of the descent state". When it is detected, it can be said that it is a reasonable time to presume that it is in an abnormal state.

Further, it is considered that the cooking container K is taken out from the grill storage 7 by the user at least once before the "set time Ti for determining the continuous abnormality of the descent state" elapses. When the state in which the relative downward movement of the temperature sensor 13 with respect to the lower support shaft 131a is detected continues over the "set time Ti for determining the continuous abnormality of the descent state", the elevating support for supporting the temperature detection unit 130 It can be estimated that a state has occurred in which the temperature sensor 13 cannot correctly detect the temperature of the bottom Ka of the cooking container K due to a failure of the means X, the mechanical linking means 120, or the like.

Therefore, in the grill according to the other embodiment 1, when the "descent state continuation time Tk" reaches the "descent state continuation abnormality determination set time Ti", the temperature sensor 13 correctly corrects the temperature of the bottom Ka of the cooking container K. It is configured to automatically execute anomaly countermeasure processing by presuming that an undetectable state has occurred.

In the grill of the other embodiment 1, as an abnormality countermeasure process, for example, combustion of the grill burner A is prohibited, or information indicating an abnormality is notified by a notification means using sound, light, or the like. , The elevating support means X, the mechanical linking means 120, and the like are configured so that the grill is not used while being in an abnormal state.

The abnormality countermeasure processing may be configured to prohibit combustion of the grill burner A illustrated above, or to perform notification by a notification means using sound, light, or the like, or both at the same time. It may be configured to be. Further, the process may be configured to be carried out by another method.

By notifying the information indicating that the abnormality is caused by the notification means, the user can notice the abnormality of the grill (the equipment constituting the grill), and maintenance is promoted.

Since the grill of the other embodiment 1 is configured as described above, the elevating support means X and the mechanical linking means 120 that support the temperature detection unit 130 fail, and the temperature detection unit 130 causes the cooking container K. It is possible to prevent the cooking from being continued in a state where the temperature of the bottom Ka of the cooking cannot be detected correctly, and it is possible to avoid a cooking failure.

[Separate Embodiment 2]
In the grill according to still another embodiment of the present invention (separate embodiment 2), the temperature sensor drop detection unit Y is relative to the support shaft 131 of the temperature sensor 13 in a state where the above-mentioned abnormality countermeasure processing is being executed. When the state of detecting the downward movement is released (that is, when the temperature sensor drop detection unit Y no longer detects the downward movement of the temperature sensor 13 with respect to the support shaft 131), It is configured so that the above-mentioned abnormality countermeasure processing is completed.

In the case of such a configuration, when the abnormality countermeasure processing is to prohibit the combustion of the grill burner as described above, or to notify the information that the abnormality is caused by the notification means using sound, light, or the like. In addition, it is possible to ignite and burn the grill burner as usual, and it is also possible to prevent unnecessary notification by sound or light, providing a grill with even better usability. Will be possible.

It should be noted that the downward movement of the temperature sensor 13 with respect to the support shaft 131 is not detected normally when the user operates the grill as in the case where the drawer portion 101 including the grill plate or the like is pulled out. Since it is a phenomenon caused by the above and it is considered unnecessary to continue the abnormality countermeasure processing at that time, it can be said that it is rational to end the abnormality countermeasure processing at the above-mentioned point.

The present invention is not limited to the gas grill that uses combustible gas as fuel as shown in the above embodiment, and can be applied to an electric grill.

The present invention can also be applied to a table stove with a grill that is installed on a table.

The present invention is not limited to the above embodiment in other respects as well, and various modifications can be made within the scope of the present invention.
