  In the conventional grill, the container presence / absence detection sensor is installed at the center part of the rear side of the grill box in the horizontal direction of the grill box, and is in contact with the center part of the rear end part of the cooking container in the width direction. Therefore, there is a disadvantage that the container presence / absence detection sensor has a complicated configuration.

  That is, since the exhaust passage forming portion that forms the exhaust passage for discharging the cooked exhaust is provided at the rear portion of the grill cabinet, the container presence / absence detection sensor is connected to the grill cabinet width of the rear portion of the grill cabinet. When installing in the center of the direction, the container presence / absence detection sensor is provided in a form protruding into the exhaust passage forming portion. Specifically, the container presence / absence detection sensor is supported by the exhaust passage forming portion in a form protruding inside the exhaust passage forming portion.

  However, among the internal space of the grill cabinet, the space that is connected to the exhaust passage inside the exhaust passage forming portion flows with the cooking exhaust made of the combustion gas of the grill burner and the gases discharged from the cooking object concentrated and flows. And since cooking exhaust gas is high temperature (for example, about 150 degreeC), in order to install a container presence detection sensor in the form which protrudes inside the exhaust passage formation part, the form which endures a container presence detection sensor to high temperature As a result, the container presence / absence detection sensor has a complicated configuration.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a grill capable of simplifying a container presence / absence detection sensor.

The grill of the present invention is provided with a cooking container support portion that supports a cooking container for cooking the food to be cooked and has a grill door at the front end portion thereof so as to be able to move out and with respect to the grill cabinet.
An exhaust passage forming portion that forms an exhaust passage for discharging cooked exhaust is provided in a rear portion of the grill warehouse, and extends upward.
A container presence / absence detection sensor for detecting the presence / absence of the cooking container is provided in a form in contact with a rear end portion of the cooking container in a state where the cooking container is housed inside the grill cabinet,
Based on the detection information of the container presence / absence detection sensor, operation control means for controlling the combustion of the grill burner for cooking is provided.
The container presence / absence detection sensor is attached to a side wall portion of the rear side of the cooking container on the side wall portion of the grill outside the exhaust passage forming portion. is there.

  That is, since the exhaust passage is not formed at the laterally outward side portion of the exhaust passage forming portion in the horizontal direction of the grill cabinet, the exhaust passage is formed in a state facing the rear end portion of the cooking container housed inside the grill cabinet. Since there is a portion of the grill cabinet wall to be connected, the container presence / absence detection sensor is in contact with the grill cabinet wall portion on the laterally outer side of the exhaust passage forming portion and the lateral end portion of the rear end portion of the cooking vessel. It will be installed in the appropriate form.

  And since the cooking exhaust gas flows in a concentrated manner through the exhaust passage formed inside the exhaust passage forming portion, the grill store on the laterally outer side of the exhaust passage forming portion in the internal space of the grill store The temperature of the space portion adjacent to the wall portion is considerably lower than the space portion connected to the exhaust passage of the exhaust passage forming portion in the internal space of the grill cabinet.

  Therefore, it is not necessary to configure the container presence / absence detection sensor in a form that can withstand high temperatures, as compared with the case where the container presence / absence detection sensor is installed in a form protruding inside the exhaust passage forming portion, so that the container presence / absence detection sensor can be simplified. is there.

  By the way, the grill wall portion on the laterally outer side of the exhaust passage forming portion is located in a state close to the rear end portion of the cooking container housed in the grill chamber, so that the container presence / absence detection sensor The support structure can be simplified.

  In short, according to the first characteristic configuration of the present invention, a grill capable of simplifying the container presence / absence detection sensor can be provided.

The second feature configuration of the grill of the present invention is in addition to the first feature configuration described above,
As the grill burner, a lower burner disposed below the cooking container is provided,
At the rear part of the grill cabinet, a central side portion in the horizontal direction of the grill cabinet is opened at the lower portion of the grill cabinet, and an opening is made across the entire width of the grill cabinet in the horizontal direction at the upper portion of the grill cabinet. The exhaust outlet is opened at

  That is, the exhaust outlet that is opened at the rear of the grill cabinet is a lower portion of the grill cabinet in order to satisfactorily discharge cooking exhaust such as the combustion gas of the lower burner and the gases discharged from the heated cooking object. In the horizontal direction of the grill cabinet, and the upper portion of the grill cabinet is opened over the entire width in the horizontal direction of the grill cabinet, and the exhaust gas thus opened is opened. In accordance with the outlet, the exhaust passage forming portion is configured to form the exhaust passage in a form communicating with the exhaust outlet.

Therefore, since the exhaust outlet at the rear part of the grill cabinet is formed in the opened state as described above, a wall portion that forms the grill cabinet is located on the side of the exhaust outlet in the lower part of the rear part of the grill cabinet. It will be located, and this wall part will be located in the state which opposes the rear-end part of the cooking container accommodated in the inside of a grill warehouse.
Therefore, the container presence / absence detection sensor is equipped by using the wall portion located on the lateral side of the exhaust opening in the lower part of the rear portion of the grill cabinet as the grill warehouse wall portion equipped with the container presence / absence detection sensor.

  And the rear side location of the wall portion located on the lateral side of the exhaust opening in the lower portion of the rear portion of the grill warehouse is a space located on the lateral outward side of the exhaust path forming portion, and a location that exists as a so-called dead space Therefore, the container presence / absence detection sensor can be appropriately equipped while using the dead space.

  In short, according to the second characteristic configuration of the present invention, in addition to the operational effects of the first characteristic configuration, it is possible to provide a grille that can be appropriately equipped with a container presence / absence detection sensor while utilizing a dead space.

The third characteristic configuration of the grill of the present invention is in addition to the first or second characteristic configuration described above,
A container contact portion provided in a state in which the container presence / absence detection sensor is movable in the front-rear width direction with respect to the sensor body and returned to the protruding position on the front side, and the container contact portion includes the sensor It is the point comprised in the form provided with the back movement detection part which detects having moved back from the protrusion position to the back position with respect to the main body.

  That is, when the cooking container support part is housed in the grill warehouse, the container contact part that is urged to return to the protruding position on the front side with respect to the sensor body is formed by the cooking container supported by the cooking container support part. And the retraction movement detection unit detects that the container contact portion has retreated from the protrusion position to the retraction position. Existence will be detected.

  Thus, the presence of the cooking container is detected by detecting the backward movement of the container abutting portion that is biased back to the protruding position on the front side with respect to the sensor body by the backward movement detection unit. When storing the cooking container support in the grill cabinet, even if the movement speed of the cooking container support is high, the container contact part moves backward, and the impact due to contact with the cooking container is reduced. Thus, damage to the container presence / absence detection sensor is suppressed.

  In other words, when the cooking container support is stored inside the grill cabinet, even if the cooking container support is moved inside the grill cabinet while moving at high speed, damage to the container presence / absence detection sensor is suppressed. However, the presence or absence of the cooking container can be detected well over a long period of time.

  In short, according to the third characteristic configuration of the present invention, in addition to the operational effects of the first or second characteristic configuration, the presence or absence of the cooking container is good over a long period of time while suppressing damage to the container presence / absence detection sensor. It is possible to provide a grill that can be detected.

The fourth characteristic configuration of the grill of the present invention is in addition to the third characteristic configuration described above,
The container contact portion is configured to include a temperature detection unit that detects an atmospheric temperature of the container presence / absence detection sensor.

That is, in the internal space of the grill cabinet, the temperature of the space portion close to the grill cabinet wall portion where the container presence / absence detection sensor is mounted, that is, the grill cabinet wall portion on the laterally outer side of the exhaust passage forming portion. The temperature of the space portion is considerably lower than the space portion connected to the exhaust passage of the exhaust passage forming portion in the internal space of the grill cabinet.
That is, the ambient temperature of the container presence / absence detection sensor detected by the temperature detection unit provided in the container contact part is usually considerably low.

  However, for example, when cooking the food to be cooked with a grill pan as a cooking container, if the food to be cooked burns, the container presence / absence detection sensor is attached in the internal space of the grill cabinet. The ambient temperature of the container presence / absence detection sensor detected by the temperature detection unit provided in the container contact portion due to the combustion gas of the cooking object flowing in the space portion adjacent to the grill wall portion to be cooked It becomes considerably hotter than the steady state.

  Therefore, there is an abnormality such as a situation in which the food to be cooked is based on the fact that the ambient temperature of the container presence / absence detection sensor detected by the temperature detection unit provided in the container contact part is considerably higher than the steady state. It is possible to determine that it has occurred and perform processing such as stopping combustion of the grill burner.

  In short, according to the fourth feature configuration of the present invention, in addition to the operational effects of the third feature configuration, a grill is provided that can determine the occurrence of an abnormal state based on the ambient temperature of the container presence / absence detection sensor. it can.

The fifth characteristic configuration of the grill of the present invention is in addition to the fourth characteristic configuration described above,
An exhaust temperature sensor for detecting the temperature in the exhaust passage is provided;
The operation control unit is configured to determine blockage of the exhaust passage based on a temperature detected by the temperature detection unit and a temperature detected by the exhaust temperature sensor.

  That is, in the internal space of the grill cabinet, the temperature of the space portion close to the grill cabinet wall portion where the container presence / absence detection sensor is mounted, that is, the grill cabinet wall portion on the laterally outer side of the exhaust passage forming portion. The temperature of the space portion is considerably lower than the space portion connected to the exhaust passage of the exhaust passage formation portion in the internal space of the grill cabinet, but when the exhaust passage is blocked, the cooking exhaust flows. The temperature becomes higher than the steady state.

Therefore, the operation control unit determines whether the exhaust passage is blocked based on the temperature detected by the temperature detector and the temperature detected by the exhaust temperature sensor.
In other words, for example, when the detected temperature of the temperature detecting unit approaches within the set value with respect to the detected temperature of the exhaust temperature sensor, the detected temperature of the temperature detecting unit and the exhaust temperature sensor are determined such that the exhaust passage is closed. The exhaust passage blockage can be determined based on the detected temperature.

  In short, according to the fifth characteristic configuration of the present invention, in addition to any of the operational effects of the fourth characteristic configuration, it is possible to provide a grill that can determine whether the exhaust passage is blocked.

(Control of the operation control unit)
The operation control unit W includes a microcomputer and controls the operation of the entire gas stove including the grill G. In the following description, the combustion for the lower burner 10 and the upper burner 11 included in the grill G is performed. The control will be described, and the combustion control for the burner 1 will be omitted.

As shown in FIG. 16, the operation control unit W controls combustion for the lower burner 10 and the upper burner 11 based on command information from the grill setting operation unit 6.
For example, when an ignition command is issued from the grill setting operation unit 6, the lower gas burner 10 and the lower burner gas amount adjusting valve 37 are operated by operating the original gas valve 31, the lower burner gas amount adjusting valve 36, and the upper burner gas amount adjusting valve 37. In addition, the fuel gas is supplied to the upper burner 11, and in addition, the ignition process is performed in which the ignition plug P for the lower burner 10 and the upper burner 11 is operated and ignition is detected by the ignition sensor R.

  Further, when a fire extinguishing command is instructed from the grill setting operation unit 6, the original gas valve 31, the lower burner gas amount adjusting valve 36, and the upper burner gas amount adjusting valve 37 are operated to be closed, A fire extinguishing process for extinguishing the burner 10 and the upper burner 11 is executed.

  In addition, in the combustion state of the lower burner 10 and the upper burner 11, when the change of the target heating power is commanded from the grill setting operation unit 6, the lower burner gas amount adjusting valve 36 and the upper burner gas amount adjusting valve 37 are operated. Then, the thermal power adjustment process for changing and adjusting the thermal power of the lower burner 10 and the upper burner 11 is executed.

  As an example of the automatic cooking control, when an automatic temperature cooking command for maintaining the target temperature is instructed from the grill setting operation unit 6, the bottom of the grill pan 9 is determined based on the detection information of the container temperature detection sensor 13. An automatic temperature cooking process for operating the lower burner gas amount adjusting valve 36 and the upper burner gas amount adjusting valve 37 is performed so that the wall temperature becomes the target temperature.

  Incidentally, although detailed description is omitted, as the automatic cooking control, there are various cooking controls other than the above-described automatic temperature cooking, and the lower burner gas amount adjusting valve 36 and the upper cooking control are provided in accordance with these various cooking controls. The burner gas amount adjusting valve 37 is operated.

Further, the operation control unit W is configured to control the combustion of the lower burner 10 and the upper burner 11 based on the detection information of the backward movement detection unit 42 of the container presence / absence detection sensor S.
That is, the operation control unit W does not detect the presence of the grill pan 9 based on the detection information of the backward movement detection unit 42 of the container presence / absence detection sensor S when an ignition command is commanded from the grill setting operation unit 6. When it determines with it being in a state, it is comprised so that the alarm process which operates alarm devices 55, such as an alarm buzzer, may be performed, without performing an ignition process.

  That is, the state where the cooking container support L is stored in the storage position of the grill cabinet 7 without mounting the grill pan 9 or the cooking container support L mounted with the grill pan 9 in the proper storage position of the grill pan 7 is provided. When the container is not stored, it is determined that the presence of the grill pan 9 is not detected based on the detection information of the backward movement detection unit 42 of the container presence / absence detection sensor S, and the execution of the ignition process is restrained. It will be.

  Further, the operation control unit W determines that the grill pan 9 is not present based on the detection information of the backward movement detection unit 42 of the container presence detection sensor S during the combustion of the lower burner 10 and the upper burner 11. In some cases, the lower burner gas amount adjusting valve 36 and the upper burner gas amount adjusting valve 37 are operated to execute a reduction process so as to reduce the heating power of the lower burner 10 and the upper burner 11.

  Then, after the reduction process is executed, the grill pan 9 is present based on the detection information of the backward movement detection unit 42 of the container presence / absence detection sensor S until a set time (for example, 15 seconds) elapses. When it is determined, the lower burner gas amount adjustment valve 36 and the upper burner gas amount adjustment valve 37 are operated to execute a thermal power return process for returning the thermal power of the lower burner 10 and the upper burner 11 to the thermal power before the reduction.

  In addition, even if a set time (for example, 15 seconds) elapses after the reduction process is executed, the grill pan 9 is not present based on the detection information of the backward movement detection unit 42 of the container presence / absence detection sensor S. When the determination is made, a fire extinguishing process for extinguishing the lower burner 10 and the upper burner 11 is performed by operating the original gas valve 31, the lower burner gas amount adjusting valve 36, and the upper burner gas amount adjusting valve 37 in a closed state. Run.

  That is, when the cooking container support L is projected forward from the grill 7 during the combustion of the lower burner 10 and the upper burner 11 (when pulled out), the backward movement detection unit 42 of the container presence / absence detection sensor S. Since the presence of the grill pan 9 is not detected based on the detected information, the combustion power of the lower burner 10 and the upper burner 11 is reduced in the grill 7 by reducing the heating power of the lower burner 10 and the upper burner 11. Flowing forward is appropriately avoided, and consumption of fuel gas for burning the lower burner 10 and the upper burner 11 is suppressed.

And after reducing the thermal power of the lower burner 10 and the upper burner 11, until the set time elapses, the cooking container support portion L provided with the grill pan 9 is again housed in the grill warehouse 7. Sometimes, the heating power of the lower burner 10 and the upper burner 11 is returned to the heating power before the decrease in order to continue cooking.
On the other hand, after the heating power of the lower burner 10 and the upper burner 11 is reduced, even when the set time elapses, when the cooking container support L provided with the grill pan 9 is not returned to the inside of the grill cabinet 7, In order to avoid useless combustion, the combustion of the lower burner 10 and the upper burner 11 is stopped.

Further, the operation control unit W is configured to control the combustion of the lower burner 10 and the upper burner 11 based on the detection information of the temperature detection unit 43 of the container presence detection sensor S and the detection information of the exhaust gas temperature sensor 26. Yes.
For example, when the temperature is 25 ° C. and the detection temperature of the container temperature detection sensor 13 is 195 ° C., the detection temperature of the exhaust temperature sensor 26 is 154 ° C., and the temperature detection unit 43 of the container presence / absence detection sensor S The detection temperature is 78 ° C.

When the temperature detected by the exhaust temperature sensor 26 exceeds the set upper limit value during the combustion of the lower burner 10 and the upper burner 11, the operation control unit W performs a fire extinguishing process to stop the combustion of the lower burner 10 and the upper burner 11. In addition, it is configured to execute an alarm process for operating an alarm device 55 such as an alarm buzzer.
That is, when the detected temperature of the exhaust temperature sensor 26 exceeds the set upper limit value due to combustion of the cooked exhaust in the exhaust passage E, the combustion of the lower burner 10 and the upper burner 11 is stopped.

Further, when the temperature detected by the temperature detector 43 of the container presence / absence detection sensor S exceeds the set upper limit value during the combustion of the lower burner 10 and the upper burner 11, the operation control unit W burns the lower burner 10 and the upper burner 11. A fire extinguishing process is executed to stop the alarm, and an alarm process for operating an alarm device 55 such as an alarm buzzer is executed.
That is, for example, when the cooking object on the upper side of the grill pan 9 burns, the ambient temperature at the location where the container presence / absence detection sensor S is installed rises, and the detection temperature of the temperature detection unit 43 of the container presence / absence detection sensor S is set. When the upper limit is exceeded, the combustion of the lower burner 10 and the upper burner 11 is stopped.

  Further, the operation control unit W compares the temperature detected by the exhaust temperature sensor 26 with the temperature detected by the temperature detection unit 43 of the container presence / absence detection sensor S during the combustion of the lower burner 10 and the upper burner 11, and the temperature detection unit When the detected temperature of 43 approaches within the set value (for example, within 30 ° C.) with respect to the detected temperature of the exhaust temperature sensor 26, a fire extinguishing process is executed to stop the combustion of the lower burner 10 and the upper burner 11, Thus, an alarm process for operating the alarm device 55 such as an alarm buzzer is executed.

  That is, due to clogging of the flame extinguishing member 25 provided in the exhaust passage E, the detected temperature of the temperature detection unit 43 of the container presence / absence detection sensor S is caused by the fact that cooking exhaust is not properly discharged through the exhaust passage E. When the detected temperature of the exhaust temperature sensor 26 approaches within a set value (for example, within 30 ° C.), the combustion of the lower burner 10 and the upper burner 11 is stopped.
