2. Description of the Related Art Conventionally, as shown in FIGS. 4 to 6, there is a gas table stove, which is a cooking device, provided with a gas grill 1 capable of heating and cooking a food such as fish. The gas grill 1 includes a grill 9 on which the food F is placed, a tray 30 which is slid out toward the front while the grill 9 is placed, and a grill burner 40 which burns the fuel gas to heat the food F. Grill storage 1
This grill burner 40 is provided at the center of the ceiling surface with the combustion surface facing downward so as to uniformly heat the food F. When an ignition operation is performed on the gas grill 1, the fuel gas ejected from the grill burner 40 is ignited and combustion is started. Accumulate.
In such a gas grill 1, when the baked fat accumulated in the saucer 30 is overheated by the radiant heat of the grill burner 40 and ignites, not only the cooking F is scorched by the combustion flame, but also the flame overflows from the exhaust port 50 of the gas grill 1. Sometimes. For this reason, the tray 30 is pre-filled with water to prevent firing due to baked fat.

[0003]

However, it is very troublesome to put water in the saucer every time prior to cooking and drain the water at the end of cooking. In addition, if the water is forgotten in the tray 30 or if the water evaporates after repeated use for a long time, the baked fat accumulated in the tray 30 may be overheated by the radiant heat of the grill burner 40 and ignited. There is. Then, the gas grill of this invention solves said subject, and aims at provision of the gas grill which does not need to pour water into a saucer.

[0004]

According to a first aspect of the present invention, there is provided a gas grill, which is provided on a ceiling of the grill for storing and cooking the food, and for cooking the food. A surface-burning burner having a combustion surface facing downward, a grill provided below the burner to place the food, and a tray provided below the grill and receiving oil falling from the food, In a gas grill including a flue that guides combustion exhaust gas generated in the grill chamber to an exhaust port, a radiation prevention plate that blocks radiation downward from the burner is provided between a combustion surface of the burner and the grill. In addition, the cooking exhaust is heated by the heat of the combustion exhaust by forming the exhaust path so that the combustion exhaust from the burner is once filled in the grill storage and the filled combustion exhaust overflows into the flue. Cook The the gist.

[0005] In the gas grill according to the first aspect of the present invention having the above-described structure, a radiation preventing plate provided between the combustion surface of the burner and the grille blocks radiant heat from the burner. Further, since the exhaust path is formed so that the combustion exhaust gas from the burner fills the inside of the grill storage and overflows the flue, the food is heated and cooked by the heat of the combustion exhaust trapped in the grill storage. Therefore, the food does not ignite because the radiant heat from the burner is blocked and the food is wrapped in the combustion exhaust gas having a low oxygen concentration. On the other hand, the saucer that receives the oil that falls from the food is
It does not ignite because the radiant heat from the burner is not interrupted and overheated. For this reason, it is not necessary to pour water into the saucer, so that it is not necessary to fill the saucer with water every time heating and cooking is performed, and the usability is improved. Moreover, since there is no evaporation of water from the saucer, it is possible to bake the food crispy.
Furthermore, since cooking is wrapped with cooking exhaust and cooked,
Fuel gas consumption can be reduced.

A cooking pot (not shown) is placed on the cooking pot b, and by pressing operation buttons 21a and 21b provided on the front of the table stove, the respective cooking stove burners 4a and 4b are ignited, and the cooking pot on 5 is heated. Is what is done.

Further, between the burner burners 4a and 4b,
A gas grill 1 for grilling fish and the like is provided, and heating is performed by pressing an operation button 21c. Gas grill 1
As shown in FIGS. 1 and 2, a grill storage 10 is provided,
The fish and the like are heated and cooked in the grill storage 10. In the grill storage 10, a surface-burning grill burner 40 for heating the food F by burning fuel gas in the center of the ceiling surface, a grill 9 for placing the food F in the middle, and a grill 9 in the lower. There is provided a tray 30 which can be slid out toward the user while being pulled out, and between the grill burner 40 and the grill 9, a large number of rectangular holes 2 for blocking radiant heat to the tray 30.
b is provided with the radiation prevention plate 2 (FIG. 3). This radiation prevention plate 2 is provided in a size about the combustion surface of the grill burner 40, and both ends are supported on both sides of the grill storage 10,
Elongated holes 2a through which fuel gas can pass are provided near both ends.

[0008] At the rear center of the grill storage 10, a partition wall 70 is provided.
An exhaust chamber 60 is provided in parallel with the air conditioner, and a communication port 71 that opens to the partition wall 70 and communicates the grill chamber 10 and the exhaust chamber 60 is provided. The communication port 71 is provided so that the upper end of the opening is slightly lower than the surface of the grill 9 where the food F is placed.

Here, the positional relationship between the mounting surface of the food F in the grill 9 and the upper end position of the communication port 71 is such that the atmosphere of the combustion exhaust gas around the food F is an oxygen concentration at which the food F is not ignited. It is set as follows. In other words, the upper end of the communication port 71 is provided below the grill 9, and the grill burner 40 and the grill burner 40 are arranged so that the combustion exhaust is trapped in the grill chamber 10 and wraps the food F so that the atmosphere around the food F becomes a low oxygen atmosphere. The positional relationship between the network 9 and the communication port 71 is set.

At the center of the front of the grill storage 10, there are provided a handle 6 which is integrally fixed to the tray 30 and pulls the tray 30 toward the front, and an opening / closing door 8 which opens and closes in conjunction with pulling the tray 30. The opening / closing door 8 is provided with a glass viewing window 8a. When pulling out the handle 6 toward you,
The pan 30 fixed to the handle 6 slides on the bottom of the grill storage 10, and the grill 9 placed on the pan 30 is simultaneously pulled out. In addition, a gap 11 through which external air can enter is provided on the bottom surface of the grill storage 10.

When an ignition operation is performed on the gas grill 1,
The fire starts over the entire grill burner 40 in the grill storage 10 and combustion is started. At this time, most of the radiant heat from the grill burner 40 is blocked by the radiation prevention plate 2 except for a part passing through the hole 2b of the radiation prevention plate 2. Then, the high-temperature combustion exhaust gas passes through a gap between the radiation prevention plate 2 and the inner wall of the grill storage 10,
While gradually passing through the long holes 2a and 2b of the radiation prevention plate 2, it gradually accumulates in the upper portion of the grill storage 10 and overflows into the lower communication port 70, flows into the exhaust chamber 60, and rises in the exhaust chamber 60 by a draft effect. Then, it flows to the exhaust port 50 which is opened at the upper rear part of the body. Simultaneously, fresh air outside is sucked from the gap 11 below the grill storage 10 by the draft effect, and is discharged together with the combustion exhaust from the communication port 71 behind the grill storage 10. The food F placed on the mounting surface of the grill 9 is shielded from the radiant heat of the grill burner 40, and
0 It is wrapped in the convection of high temperature combustion exhaust gas filling the upper part and cooked. The grill burner 40 is a primary air burner 4 that supplies all air required for combustion as primary air.
Since it is 0, good combustion is maintained even if the inside of the grill storage 10 is filled with the combustion exhaust gas.

As described above, in the gas grill of this embodiment, the grill burner 40 is provided at the center of the ceiling surface and the grill 9
Radiant heat is blocked by the radiation prevention plate 2, so that the pan 3
Heating to the roasting oil accumulated at zero is reduced. Further, the combustion exhaust gas in the grill storage 10 convects from above to below, and the convection heat wraps the food F on the grill 9 so that the temperature of the grill oil can be reduced to the ignition point without impairing the cooking performance. It can be reduced to: In addition, fresh air outside is sucked from the gap 11 in front of the grill storage 10 by the draft effect, cools the tray 30, and is discharged together with the combustion exhaust from the rear communication port 16. Therefore, even if the tray 30 is not filled with water, ignition of the food F dropped on the tray 30 by the burning oil is prevented.

Conventionally, the surface of the pan 30 has been subjected to a surface treatment of an enamel. However, since the temperature of the pan 30 is lowered by convection heating, a fluorine coating can be used instead of the enamel. When the fluorine coating is used, dirt does not stick and the tray 30 can be easily cleaned. In other words, even if the boiled-up spilled by the food F or the fallen baked oil is dried on the saucer 30, it can be easily wiped off with a soft cloth or kitchen paper without sticking. Cleaning of the tray 30 performed later can be simplified. Moreover, since it does not break like an enamel, the yield is improved and the productivity is improved.

Further, in the gas grill of this embodiment, since the combustion exhaust gas wraps the food F and bake it uniformly by convection heating instead of radiant heating, cooking of frozen foods such as grilled fish, gratin, pizza, tempura, A wide range of cooking can be performed until the fried food is reheated. Further, by appropriately setting the number and size of the holes 2b of the radiation prevention plate 2, the radiation heat can be uniformly reduced, and a suitable scorch can be uniformly formed. In addition, since the water is not poured into the tray 30, the water does not evaporate from the tray 30 into the grill storage 10, so that the cooked food F is crisply baked, and the baked time is the same as before, and the baked food becomes more delicious. .

Further, since the heating of the food F is performed by convection confining the combustion exhaust gas, the amount of heat in the combustion exhaust gas can be efficiently used, and the gas consumption of the gas grill can be reduced to about one half of the conventional one. Can be reduced (for example, 1860 kcal /
h → 950 kcal / h).

Moreover, the inside of the grill storage 10 can be efficiently heated and the temperature of the pan 30 can be kept low, so that there is no need to fill the pan 30 with water, and when the gas grill is pulled out, hot water may fly out. There is no need to worry about spills and burns when carrying the gas grill.

Further, the radiation preventing plate 2 has an effect of preventing grilled oil and oil smoke scattered from the food F from adhering to the grill burner 40.

The embodiments of the present invention have been described above.
The present invention is not limited to these embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention. For example, the radiation prevention plate may completely block radiation heat from grill burner 40 without providing hole 2b. Further, since convection heating is used instead of radiant heating, the gas consumption may be reduced, and the combustion surface of the grill burner may be provided small.

[0019]

As described above in detail, the gas grill of the present invention has an excellent effect that the trouble of filling the tray with water is eliminated and the usability is improved. In addition, the food can be baked crisp and fuel gas can be saved.
