Description

The present invention is a heating chamber equipped with a grill to place the food to be cooked and a juice tray located below the grill,
A burner that burns gas fuel in the heating chamber and heats an object to be cooked placed on the grill;
An exhaust passage that is provided to extend upward from a rear portion or a lateral side portion of the heating chamber, and causes the combustion gas of the burner to flow upward and exhaust from an exhaust port at an upper end;
A porous catalyst body that is disposed in the exhaust passage and purifies the combustion gas of the burner;
Due to the suction action caused by the combustion gas of the burner rising and flowing through the exhaust passage, the outside air for cooling is introduced into the heating chamber through the intake hole to cool the soup pan, and the exhaust passage The present invention relates to a grill configured to flow to a lower region in an inlet side portion.

  Such a grill causes the combustion gas of the burner to flow upward through the exhaust passage and is discharged from the exhaust port. Thus, the outside air for cooling is discharged from the intake hole by the suction action caused by the combustion gas of the burner flowing upward through the exhaust passage. It is introduced into the heating chamber, and the introduced outside air is made to flow so as to cool the juice tray, and then flows to the lower region in the inlet side portion of the exhaust passage, and is discharged through the exhaust passage. It is possible to prevent ignition of oil or the like falling from the object to be cooked without adding water to the soup pan (see, for example, Patent Document 1).

  The burner combustion gas discharged through the exhaust passage contains unburned gas fuel and gas containing odorous components such as smoke generated from the cooking object. Although not described in Patent Document 1 for discharging, a porous catalyst body that purifies the combustion gas of the burner is disposed at the outlet side portion in the exhaust passage in the exhaust passage as viewed in the flow direction of the combustion gas. It will be provided to cover the whole area.

JP 2005-102846 A

By the way, the catalyst body is activated by being heated by the combustion gas of the burner flowing through the exhaust passage, and exhibits the action of purifying the combustion gas of the burner. In order to heat, the catalyst body heating part which heats a catalyst body may be provided.
The outside air introduced through the intake holes and flowing to the lower region in the inlet side portion of the exhaust passage has a temperature lower than that of the combustion gas of the burner, but in the conventional grill, the inlet side portion of the exhaust passage The outside air that has flowed to the lower region of the gas is mixed with the combustion gas of the burner, and the combustion gas of the burner whose temperature has been lowered by the mixing of the outside air flows through the exhaust passage and flows to the catalyst body.
For this reason, when purifying the combustion gas while heating the catalyst body only with the heat of the combustion gas, it is difficult to raise the temperature of the catalyst body, and there is a possibility that the purification action of the combustion gas cannot be fully exhibited. In the case where a catalyst body heating section is provided, the catalyst body can be sufficiently heated by heating by the catalyst body heating section, but it is difficult to raise the temperature of the catalyst body with combustion gas. Therefore, it is necessary to increase the heating amount of the catalyst body heating part, and there is a possibility that the energy consumption of the catalyst body heating part increases.
In short, the conventional grill cannot properly heat the catalyst body with the combustion gas, and an improvement is desired.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a grill capable of appropriately heating a catalyst body with combustion gas.

The grill of the present invention is a heating chamber equipped with a grill net for placing an object to be cooked and a juice tray located below the grill,
A burner that burns gas fuel in the heating chamber and heats an object to be cooked placed on the grill;
An exhaust passage that is provided to extend upward from a rear portion or a lateral side portion of the heating chamber, and causes the combustion gas of the burner to flow upward and exhaust from an exhaust port at an upper end;
A porous catalyst body that is disposed in the exhaust passage and purifies the combustion gas of the burner;
Due to the suction action caused by the combustion gas of the burner rising and flowing through the exhaust passage, the outside air for cooling is introduced into the heating chamber through the intake hole to cool the soup pan, and the exhaust passage It is configured to flow to the lower region in the inlet side portion,
The first characteristic configuration is a partition body that divides the exhaust passage vertically so as to separate a flow region in which the combustion gas of the burner flows and a flow region in which the outside air flows into at least a portion of the exhaust passage on the heating chamber side. Is provided,
The catalyst body is disposed in a flow area in the exhaust passage where the combustion gas of the burner flows.

That is, at least a portion on the heating chamber side in the exhaust passage is partitioned vertically by a partition body into a flow area where the burner combustion gas flows and a flow area where the outside air flows, so that the burner combustion gas is burned in the exhaust passage. The catalytic body disposed in the flow area where the combustion gas of the burner flows into the flow area where the combustion gas flows and flows through the flow area, and the combustion gas of the burner in the exhaust passage flows is heated by the combustion gas of the burner flowing through the flow area. The outside air introduced through the intake holes and flowing to the lower region in the inlet side portion of the exhaust passage flows into the flow area where the outside air flows in the exhaust passage and flows through the flow area.
That is, the catalyst body is heated by the combustion gas of the burner in which the mixing of the outside air introduced through the intake holes is suppressed and the temperature drop is suppressed, so that the temperature of the catalyst body that is heated by the combustion gas is increased. Can be
For this reason, when purifying the combustion gas while heating the catalyst body only with the heat of the combustion gas, it becomes easy to raise the temperature of the catalyst body, and the purification action of the combustion gas can be appropriately exhibited. Become. In addition, in the case where a catalyst body heating part is provided, the temperature of the catalyst body is easily increased by combustion gas. Therefore, when the catalyst body is heated sufficiently by heating by the catalyst body heating part, the catalyst body heating is performed. By reducing the heating amount of the part, it is possible to reduce the energy consumption of the catalyst body heating part.
In short, the present inventors have provided a grill that can appropriately heat the catalyst body with combustion gas.

In addition to the first feature configuration, the second feature configuration is
A suppression body that suppresses the flow of liquid components floating in the combustion gas of the burner to the catalyst body side is provided at a portion upstream of the catalyst body in the exhaust passage in the combustion gas flow direction. In the point.

That is, since the liquid component floating in the combustion gas of the burner is prevented from flowing to the catalyst body side, the liquid component floating in the combustion gas of the burner is prevented from adhering to the catalyst body. The
Since gas such as smoke generated from the food to be cooked includes liquid components that are difficult to evaporate such as oil, the combustion gas of the burner containing gas generated from such food to be cooked includes liquid components. When such a liquid component adheres to the catalyst body, the adhering liquid component is difficult to evaporate. Therefore, the portion of the catalyst body where the combustion gas of the burner contacts is gradually narrowed, and the purification performance of the catalyst body gradually increases. descend.
Therefore, by suppressing the liquid component floating in the combustion gas of the burner from adhering to the catalyst body with the suppressor, it is possible to suppress the narrowing of the portion of the catalyst body that contacts the combustion gas of the burner. Therefore, it can suppress that the purification performance of a catalyst body falls.
Accordingly, the durability of the catalyst body can be improved.

The third feature configuration is in addition to the second feature configuration,
The said suppression body exists in the point comprised with the some plate-shaped body arranged in parallel along the combustion gas flow direction so that a serpentine flow path may be formed.

That is, the combustion gas of the burner flows while changing the direction of the meandering flow path formed by a plurality of plate-like bodies arranged in parallel along the combustion gas flow direction against each plate-like body. When the combustion gas hits the plate, the liquid floating in the combustion gas of the burner adheres to the plate, so that the liquid floating in the combustion gas of the burner is prevented from adhering to the catalyst body. It will be.
And even if a liquid component floating in the combustion gas of the burner adheres to each plate-like body, the area of the flow path that allows the flow of combustion gas by each plate-like body is hardly reduced, so a grill is used. Even if the time becomes longer, it becomes possible to prevent the ventilation resistance of the exhaust passage from increasing, and while suppressing the liquid component floating in the combustion gas of the burner from adhering to the catalyst body, A suppressor for properly discharging the combustion gas and appropriately cooling the juice receiving tray by properly introducing the outside air for cooling, and as a result, maintaining the state in which the juice receiving tray is appropriately cooled. Maintenance such as cleaning can be reduced.
By the way, by configuring the suppressor with, for example, a mesh body, and attaching the liquid component floating in the burner combustion gas to the wire constituting the mesh body when the burner combustion gas passes through the mesh body, It is assumed that the liquid component floating in the burner combustion gas is prevented from adhering to the catalyst body. However, in this case, if the liquid component adheres to the wire constituting the mesh body, the hole through which the combustion gas of the burner in the mesh body passes becomes small, so that the ventilation resistance of the exhaust path is likely to increase, and the exhaust path When the ventilation resistance is increased, the combustion gas of the burner becomes difficult to be discharged, and the outside air for cooling becomes difficult to be introduced and the juice receiving tray cannot be cooled appropriately, so that the juice receiving tray is kept properly cooled. Therefore, it is necessary to increase the frequency of maintenance, and the burden of maintenance becomes heavy.
Therefore, the durability of the catalyst body can be improved while reducing maintenance for maintaining the state in which the soup pan is properly cooled.

The fourth feature configuration is in addition to any one of the first to third feature configurations,
The catalyst body heating part for heating the catalyst body is provided.

In other words, the catalyst body heating section can be heated to sufficiently raise the temperature of the catalyst body to accurately exhibit the action of purifying the combustion gas.
In particular, when the burner combustion amount is changed and adjusted, when the burner combustion amount is adjusted to a small amount side, it is difficult to heat the catalyst body sufficiently by heating with only the combustion gas. Even in such a case, the catalyst body can be sufficiently heated.
Therefore, the temperature of the catalyst body can be accurately increased and the action of purifying the combustion gas can be exhibited accurately.

In addition to any one of the first to fourth feature configurations described above, the fifth feature configuration is
The exhaust path is connected to the rear portion of the heating chamber in an obliquely upward posture that is positioned upward as it moves rearward from the heating chamber,
The partition body is provided at a portion of the exhaust passage on the heating chamber side.

  That is, the exhaust path is connected to the rear part of the heating chamber in an obliquely upward posture that is located upward as it moves away from the heating chamber, and the partition body is provided in the heating chamber side portion in the exhaust path. The burner combustion gas and outside air that have flowed to the inlet of the exhaust passage will flow into the exhaust passage without greatly changing the direction, and the burner combustion gas and outside air will easily flow into the exhaust passage, and the burner combustion Since mixing of gas and outside air before it flows into the exhaust passage is suppressed, the burner combustion gas and outside air are accurately separated from the range where the basin is partitioned by the partition in the exhaust passage Then, after the burner combustion gas and the outside air pass through the range in which the basin is partitioned by the partition in the exhaust passage, the outside air is mixed with the burner combustion gas, and the temperature of the outside air is thus mixed. Combustion gas reduced burner is to be discharged from the exhaust port.

And since the combustion gas of the burner in which the mixing of the outside air is suppressed can flow in the basin partitioned by the partition in the exhaust passage, the combustion gas of the burner in which the temperature drop due to the mixing of the outside air is further suppressed The catalyst body can be heated, the catalyst body can be heated to a higher temperature, and the combustion gas of the burner can be further appropriately purified.
In addition, since the temperature of the combustion gas of the burner discharged from the exhaust port is reduced due to the outside air being mixed, it is possible to prevent the temperature of the combustion gas of the burner discharged from the exhaust port from increasing.
Therefore, the burner combustion gas can be more appropriately purified while avoiding an increase in the temperature of the burner combustion gas discharged from the exhaust port.

Further, the suppressor F is formed of two plates, that is, an upper plate 32t and a lower plate 32u arranged side by side in the combustion gas flow direction so as to form a meandering flow path. Consists of the body.

In other words, the lower side surface 27a of the exhaust pipe 27 is positioned so as to move away from the heating chamber K to the rear side over the entire region from the location connected to the grill 25 to the grill exhaust port 28. The partition 33 is provided in a rearward and obliquely upward posture, and the partition 33 is substantially parallel to the lower side surface 27a of the exhaust tube 27 at a position biased downward in a portion of the exhaust passage R on the heating chamber K side ( That is, the left and right side edge portions are provided in contact with and supported by the left and right side surfaces 27c of the exhaust pipe 27 in a rearward and obliquely upward posture.

  The catalyst body 31 is configured such that an oxidation catalyst made of a noble metal such as platinum or palladium is supported on a porous body formed so as to be ventilated with ceramic. That is, the combustion gas of the grill burner 2 is purified by oxidizing the unburned portion of the gas fuel contained in the combustion gas of the grill burner 2 and the odor component contained in the gas such as smoke generated from the cooking object N. It will be.

Then, such a catalyst body 31 is partitioned in a state where a gap 34 is formed between the lower edge portion and the upper edge portion of the partition body 33 at a position close to the rear of the partition body 33. The upper edge is on the upper side surface 27b of the exhaust tube 27 and the left and right side edges are the left and right side surfaces 27c of the exhaust tube 27 in a posture that is positioned at substantially the same height as the upper edge portion of the body 33 and is substantially perpendicular.

That is, the catalyst body 31 is provided at the rear end portion of the combustion gas flow region Re of the exhaust passage R so as to cover the entire combustion gas flow region Re as viewed in the combustion gas flow direction of the combustion gas flow region Re. All of the combustion gas of the grill burner 2 that flows through Re passes through the catalyst body 31.

In the upper plate 32t and the lower plate 32u, the upper edge of the lower plate 32u is spaced in front of the lower edge of the upper plate 32t. In a state where the lower edge portion of the upper plate-like body 32t overlaps with the lower plate-like body 32u when viewed in the vertical direction, each of the upper sides is in a forward obliquely upward posture positioned forward. Is provided.
The upper plate-like body 32t has its lower edge located at the middle in the vertical direction of the rear end in the combustion gas flow region Re, its upper edge on the upper side surface 27b of the exhaust tube 27, and left and right side edges.

The combustion gas Eg of the grill burner 2 contains unburned gas fuel and gas containing odor components such as smoke generated from the cooking object N.
The combustion gas Eg of the grill burner 2 containing unburned gas fuel and gas generated from the cooking object N flows rearward in the heating chamber K and flows into the combustion gas flow area Re of the exhaust passage R. And flows through the combustion gas flow area Re in a form that passes through the meandering flow path formed by the lower plate-like body 32u and the upper plate-like body 32t and then passes through the catalyst body 31. When passing through the combustion gas flow area Re, the combustion gas Eg of the grill burner 2 is mixed with the outside air Oa that has passed through the outside air flow area Ro as described later, and the combustion gas Eg of the grill burner 2 thus mixed with the outside air Oa is The gas flows upward in the exhaust path R and is discharged from the grill exhaust port 28 at the upper end.
A plurality of parts are provided in a state where they are dispersed in the bottom part of the grill cabinet 25 and the bottom side parts of the left and right side wall parts by a draft action caused by the combustion gas Eg of the grill burner 2 flowing upward in the exhaust passage R. The outside air Oa is introduced into the heating chamber K through the air intake hole 25b, and the introduced outside air Oa flows toward the rear side along the bottom surface and the left and right side portions of the soup pan 29, so that the outside airflow in the exhaust path R When it flows into the path Ro and flows through the outside air flow path Ro, it is mixed with the combustion gas Eg of the grill burner 2 that has passed through the combustion gas flow area Re as described above.

The combustion gas Eg of the grill burner 2 passes through the meandering flow path formed by the lower plate-like body 32u and the upper plate-like body 32t, and the lower plate-like body 32u and the upper plate-like body 32t. When the combustion gas Eg of the burner hits the lower plate-like body 32u or the upper plate-like body 32t, the liquid component floating in the combustion gas Eg of the burner is moved to the lower side. Since it adheres to the plate-like body 32u and the upper plate-like body 32t, the liquid component floating in the combustion gas Eg of the burner is prevented from adhering to the catalyst body 31.
Since the catalyst body 31 is heated by the combustion gas Eg of the grill burner 2 in which mixing of the outside air Oa introduced through the intake holes 25b is suppressed and the temperature decrease is suppressed, the temperature of the catalyst body 31 is increased by heating of the combustion gas Eg of the grill burner 2. The temperature of the catalyst body 31 to be increased can be increased.
And the catalyst body 31 of this embodiment has the performance which can exhibit a purification | cleaning effect appropriately only by heating only the combustion gas Eg of the grill burner 2 by which mixing of the external air Oa is suppressed and the temperature fall is suppressed. Therefore, the combustion gas Eg of the grill burner 2 can be appropriately purified by the catalyst body 31 and discharged.
In addition, since the temperature of the combustion gas Eg of the grill burner 2 discharged from the grill exhaust port 28 of the exhaust path R is lowered due to the mixing of the outside air Oa, the temperature of the combustion gas Eg discharged from the grill exhaust port 28 is high. Can be avoided.

The liquid adhering to the front and back surfaces of the upper plate-like body 32t flows along the upper plate-like body 32t and flows from the lower end edge of the upper plate-like body 32t to the lower plate-like body 32u. The liquid component dropped onto the back surface of the lower plate-like body 32u flows along the back surface together with the liquid component adhering to the back surface of the lower plate-like body 32u, and the catalyst body 31. Passing through a gap 34 between the lower edge of the exhaust pipe 33 and the upper edge of the partition 33, it drops onto the inclined lower side surface 27 a of the exhaust tube 27 and further travels along the lower side surface 27 a of the exhaust tube 27. It flows and drops on the bottom surface of the grill box 25.
The liquid adhering to the surface of the lower plate-like body 32u flows along the surface of the lower plate-like body 32u and reaches the upper surface of the inclined partition 33, and further, the partition 33 It flows along the upper surface of the grill and drops onto the bottom surface of the grill cabinet 25.
Then, the liquid accumulated on the bottom surface of the grill box 25 can be removed through the opening for putting in and out the food in the grill box 25.

[Another embodiment]
Next, another embodiment will be described.
(A) As shown in FIGS. 5 and 6, an electric heater 36 may be provided as a catalyst body heating unit that heats the catalyst body 31.
When the explanation is added, the electric heater 36 is configured in a rod shape, and the three rod-shaped electric heaters 36 are arranged in the posture in which the longitudinal direction thereof is in the horizontal direction, and the upper side and the lower side 2 in the combustion gas flow region Re of the exhaust path R. In the space between the plate-like bodies 32t, 32u and the catalyst body 31, they are arranged in a state of being spaced apart in the vertical direction.
The controller H starts the heating operation of the electric heater 36 when the ignition of the grill burner 2 is instructed by the setting input panel 22 for the grill, and the fire extinguishing of the grill burner 2 is instructed by the setting input panel 22 for the grill. And the heating operation of the electric heater 36 is stopped.

When the catalyst body 31 is heated by the combustion gas of the grill burner 2 and the three electric heaters 36 in which mixing of outside air is suppressed and temperature decrease is suppressed, the catalyst body 31 can be appropriately purified. Supply power to the three electric heaters 36 necessary for heating to the temperature is preset and stored in the control unit H as set supply power.
The control unit H is configured to heat the three electric heaters 36 with the set supply power.

  Since the three electric heaters 36 are provided upstream of the catalyst body 31 in the combustion gas flow direction, the combustion gas heated by the electric heater 36 passes through the catalyst body 31, and thus the electric heater 36. Thus, the catalytic body 31 can be efficiently heated, so that the catalytic body 31 is heated by the combustion gas of the grill burner 2 in which mixing of outside air is suppressed and the temperature drop is suppressed. Thus, the power consumption of the electric heater 36 can be further reduced while heating the catalyst body 31 to a temperature at which the purification action can be appropriately exhibited.

  Further, when the combustion amount of the grill burner 2 is adjusted to a small amount side, the heating of the grill burner 2 with only the combustion gas hardly makes the catalyst body 31 sufficiently high in temperature. The electric heater 36 may be heated when the combustion amount of the grill burner 2 instructed by 22 is equal to or less than the set combustion amount.

(B) When the suppressor F is constituted by a plurality of plate-like bodies arranged in parallel along the combustion gas flow direction so as to form a meandering flow path, the number of plate-like bodies is the same as that in the above embodiment. It is not limited to the two illustrated, and may be three or more.
In addition, the specific configuration of the suppressing body F is not limited to the configuration illustrated in the above embodiment, and may be configured by a net-like body or a porous body, for example.
