Japanese Patent Laid-Open No. 2000-245624

In the conventional gas grill, a pair of left and right lower heating burners are provided.However, for the sake of simplifying the configuration, the lower heating burners should be provided only on one side of the left and right lateral outer sides of the roasting chamber. It is possible to
By the way, if the number of lower heating burners installed decreases, the number of auxiliary equipment such as igniters and ignition detection units installed on the lower heating burners also decreases, so the number of lower heating burners installed will not decrease. , Is effective in simplifying the configuration.

However, if the lower heating burner is provided only on one side of the left and right lateral outer portions of the roasting chamber, the heating of the lower heating burner by the flame causes the lower heating burner in the lateral width direction of the cooktop. However, there is a risk of uneven baking on the lower surface of the food, which is difficult to put into practical use.

The present invention has been made in view of the above situation, and an object thereof is to achieve good cooking by suppressing the occurrence of baking unevenness on the lower surface of a food item while simplifying the configuration. The point is to provide a gas grill that can.

The gas grill of the present invention is a roasting chamber in which a bottom portion, both left and right side portions, a front portion and a rear portion are surrounded by a wall-like body and a hot air introduction opening is formed in the upper portion,
A cooking product placing body provided inside the roasting chamber so as to place a cooking product,
A side hot air passage formed in a laterally outer side portion of the roasting chamber in a state of going vertically and communicating with the hot air introducing opening;
An upper heating burner provided at a lower portion of the side hot air passage in a state in which hot air directed upward by blowing a flame upward and burning to supply the side hot air passage,
A lower heating burner that burns by burning a flame along the horizontal direction from the lateral outer side of the roasting chamber to the lower side of the food placing body,
An exhaust port formed in the rear part of the roasting chamber so as to exhaust the hot air supplied to the roasting chamber, and the characteristic configuration thereof is
The lower heating burner is provided on one side of the left and right lateral outer portions of the roasting chamber,
Of the left and right lateral parts of the roasting chamber, on the lateral part on the side opposite to the side on which the lower heating burner is arranged, hot air from the flame of the lower heating burner is transferred to the upper heating burner. A hot air inflow hole is formed to flow to the installation location ,
The exhaust port is formed in the rear portion of the roasting chamber in a portion above the cooking product support .

That is, since the side hot air passage is heated by the flow of hot air in the upper heating burner or the flame of the upper heating burner, the temperature rises. Since the installation location of the upper heating burner becomes negative pressure, hot air from the flame of the lower heating burner provided on one of the left and right lateral outside parts of the roasting chamber passes through the hot air inlet hole It will flow to the location where the heating burner is installed.

As a result, the flame of the lower heating burner is formed so as to extend toward the hot air inflow hole, so that the hot air of the flame of the lower heating burner improves the entire width of the cooktop. This makes it easier to heat, and it is possible to suppress the occurrence of uneven baking on the lower surface of the cooked food.
That is, it is possible to suppress the occurrence of baking unevenness on the lower surface of the food item and to perform good heating and cooking while providing a single lower heating burner.

By the way, in order to spread the hot air from the flame of the lower heating burner over the entire width of the cooking platform, it is conceivable to install a blower fan to blow the hot air from the flame of the lower heating burner. However, in this case, the installation of the blower fan complicates the overall configuration.

On the other hand, in this characteristic configuration, the hot air due to the flame of the single lower heating burner is cooked by the simple configuration of forming the hot air inflow hole while effectively utilizing the side hot air passage and the upper heating burner. It is possible to cover the entire object mounting body in the widthwise direction.

In short, according to the characteristic configuration of the gas grill of the present invention, it is possible to perform good heating and cooking while suppressing the occurrence of uneven baking on the lower surface of the food item, while simplifying the configuration.

Further , since the exhaust port is formed in the rear part of the roasting chamber above the food placing body, the hot air of the lower heating burner is caused to properly flow to the side hot air passages, and the lower heating is performed. The heating using the hot air of the burner for heating can be performed well.
That is, the hot air due to the flame of the lower heating burner flows through the hot air inflow hole to the location where the upper heating burner is installed, then flows through the side hot air passage, and flows from the hot air introducing opening into the roasting chamber. By doing so, even after flowing to the installation location of the upper heating burner, it can be effectively used for heating the cooked food.

On the other hand, for example, if the exhaust port is formed so as to open in the lower portion of the rear part of the roasting chamber below the food placing body, a part of the hot air of the lower heating burner is discharged to the side. It does not flow to the partial hot air passage, but short-circuits to the exhaust port, which makes it difficult to effectively use the hot air of the lower heating burner to heat the food.

In short, according to the feature structure of the gas grill of the present invention can be effectively utilized hot air bottom heating burner for heating the food.

A further characteristic configuration of the gas grill of the present invention is that the food placing body is formed as a non-ventilable plate-like body that partitions the inside of the roasting chamber into upper and lower parts.

That is, since the food placing body is configured as a non-ventilating plate-like body that divides the inside of the roasting chamber into upper and lower parts, the inside of the roasting chamber is defined by the upper space and the lower space of the food placing body. By partitioning the hot air into the space above the food placing body from the hot air introduction opening, the flow of heat into the space below the food placing body is suppressed, and the hot air of the lower heating burner is suppressed. At, the lower surface of the food placing body can be appropriately heated.

In other words, if the cooktop is configured to be ventilated by a net-like body or the like, a negative pressure will be applied to the installation location of the upper heating burner, so that the cooktop is above the cooktop from the hot air introduction opening. The hot air introduced into the space flows into the space below the food placing body through the food placing body and into the hot air inflow hole. There is a risk that the heating of the lower surface of the food placing body is adversely affected by the hot air of the flame of the lower heating burner.

According to this characteristic configuration, since the food placing body is configured as a plate that is impermeable to air, the hot air in the space above the food placing body passes through the food placing body and Since the flame of the lower heating burner can be appropriately expanded toward the hot air inflow hole by suppressing the flow to the space below the placing body, the lower heating burner can be used to place the cooked product. The underside of the body can be heated appropriately.

In short, according to the further characteristic configuration of the gas grill of the present invention, the lower surface of the cooktop can be appropriately heated by the lower heating burner.

A further characteristic configuration of the gas grill of the present invention is that each of the left and right lateral sides of the roasting chamber is provided with a projecting portion projecting inwardly of the roasting chamber in a form extending in the front-rear direction,
The cooking product mounting body is mounted on the projecting portion in a form in which the left and right ends are in close contact with the projecting portion.

That is, since the left and right end portions of the cooked product placing body are placed in close contact with the projected portions provided on both the left and right lateral sides of the roasting chamber, the cooked product placing body is placed on the projected portion, so The space between the left and right ends of the body and the left and right lateral sides of the roasting chamber is sealed so that the hot air in the upper space of the food placing body does not flow into the lower space of the food placing body. be able to.
In other words, the left and right ends of the food placing body are placed on the protrusions provided on both the left and right sides of the roasting chamber, and the left and right ends of the food placing body and the roasting chamber are roasted. The space between the left and right lateral portions of the chamber can be sealed so that the hot air in the upper space of the food placing body does not flow into the lower space of the food placing body.

Then, between the left and right end portions of the food placing body and the left and right lateral sides of the roasting chamber, the hot air in the upper space of the food placing body flows into the lower space of the food placing body. Since it can be sealed so as to prevent the hot air in the upper space of the food placing body from flowing into the lower space of the food placing body, the flame of the lower heating burner can be more appropriately suppressed. Can be appropriately extended toward the hot air inflow hole, so that the lower surface of the cooktop can be heated more appropriately by the lower heating burner.

In short, according to the further characteristic configuration of the gas grill of the present invention, between the left and right end portions of the food placing body and the left and right side portions of the roasting chamber are sealed with a simple structure, The lower surface of the food placing body can be heated more appropriately by the heating burner.

A further characteristic configuration of the gas grill of the present invention is that a weir portion that rises upward is formed on the periphery of the food placing body.

That is, since the weir is formed on the periphery of the cooking object, the weir does not flow to the outside even if the hot juice comes out of the food placed on the food placing body. It can be accepted.

Therefore, it is not necessary to provide a saucer for receiving the juice that falls from the cooktop on the lower side of the cooktop, so that the bottom of the roasting chamber can be prevented from being soiled and the structure can be further improved. Can be simplified.

In short, according to the further characteristic configuration of the gas grill of the present invention, it is possible to further simplify the configuration while avoiding contamination of the bottom of the roasting chamber.

In a further characteristic configuration of the gas grill of the present invention, the side hot air passage is a lateral side portion of the left and right lateral sides of the roasting chamber opposite to the side on which the lower heating burner is arranged. Provided on the outer side of
At the upper part of the roasting chamber, an upper hot air passage along the lateral width direction of the roasting chamber is provided in a form that communicates with the upper end of the side hot air passage and is separated from the inside of the roasting chamber,
The hot air introducing opening is formed at a position on one lateral side of the upper portion of the roasting chamber where the lower heating burner is arranged so as to communicate with the upper hot air passage.

That is, of the left and right lateral sides of the roasting chamber, the single lateral hot air passage is located at the outer side of the lateral side opposite to the side on which the lower heating burner is arranged. The hot air flowing in the side hot air passage flows through the upper hot air passage provided in the upper part of the roasting chamber to one lateral side of the upper part of the roasting chamber where the lower heating burner is arranged. Then, the hot air is introduced into the roasting chamber through the hot air introduction opening formed at one lateral side thereof.

Therefore, since the single side hot air passage is provided, the single upper heating burner is provided, so that the configuration can be further simplified.
By the way, if the number of upper heating burners installed decreases, the number of incidental equipment such as igniters and ignition detection units installed for the upper heating burners also decreases, so the number of installed upper heating burners will not decrease. , Is effective in simplifying the configuration.

Further, although it has a single side hot air passage, it has an upper hot air passage, and the opening for hot air introduction is opposite to the side where the side hot air passage is located in the lateral width direction of the roasting chamber. Since it is formed at one side on the side where the lower heating burner is arranged, the temperature distribution in the upper space of the food placing body inside the roasting chamber is made uniform, and the food placing is performed. The upper side of the body is easily heated well.

That is, the space above the food placing body in the roasting chamber is radiant heat due to hot air flowing through the side hot air passage, radiant heat due to hot air flowing through the upper hot air passage, and a hot air introducing opening. Although it is heated by the hot air supplied from the side, the side hot air is located on the side opposite to the side hot air passage side in the width direction of the roasting chamber. The radiant heat due to the hot air flowing through the passage and the hot air supplied from the hot air introducing opening cause the space above the food placing body in the roasting chamber to have a good heat balance in the lateral width direction. Can be heated.

To add an explanation, when the hot air introduction opening is formed at one lateral side where the side hot air passage is located in the lateral width direction of the roasting chamber without providing the upper hot air passage, the side hot air passage is formed. Radiant heat due to the flow of hot air and hot air supplied from the hot air introduction opening make it easier for the side where the side hot air passage is located in the upper space of the cooktop to be heated than the opposite side, and to cook The heat balance in the lateral width direction in the upper space of the food placing body becomes poor, and it becomes difficult to heat the upper surface side of the food placing body satisfactorily.

In short, according to the further characteristic configuration of the gas grill of the present invention, by providing a single upper heating burner, it is possible to further simplify the configuration, but of the food placing body. The upper surface side can be heated well.

A further characteristic configuration of the gas grill of the present invention is that the exhaust port is a portion in an upper portion of the rear portion of the roasting chamber above the food placing body and opposite to a side where the lower heating burner is arranged. It is located at a point on one lateral side of.

That is, since the exhaust port is formed in the rear part of the roasting chamber in the upper part of the cooktop on the side opposite to the side on which the lower heating burner is arranged, The hot air introduced from the hot air introduction opening formed at one lateral side on the side where the lower heating burner is arranged, which is opposite to the side where the side hot air passage is located in the lateral direction of the baking chamber, is The fluid flows while traversing the space above the food placing body inside the baking chamber along the lateral width direction of the roasting chamber.

In this way, the hot air introduced from the hot air introduction opening flows through the space above the food placing body in the roasting chamber while traversing along the lateral width direction of the roasting chamber. The hot air introduced from the hot air introducing opening can more favorably heat the upper surface side of the food placing body.

In short, according to the characteristic configuration of the gas grill of the present invention, the hot air introduced from the hot air introducing opening can more favorably heat the upper surface side of the cooktop.
