And a tray 30 which is slid out to the front with the grill 20 placed thereon, a grill burner 40 which burns the fuel F by burning the fuel gas, and a grill storage 1 for storing these.
0, and a flue 600a that guides the flue gas generated by the combustion to the outside of the body at the back of the grill storage 10. In such a grill, heating is started after a certain amount of water has been put into the saucer 30 in advance during cooking, and the oil and fat components coming out of the object F such as fish baked on the grill 20, that is, grilling Prevents burning oil from igniting by dropping oil onto water. However, if the user forgets to fill the tray 30 with water, the grilled oil may ignite and ignite, and the flame in the grill storage 10 may overflow from the exhaust port 50.

[0003] In addition, an object to be cooked, such as a dried dried product having a large amount of fat or oil, may itself ignite. Although such a thing is unlikely in normal use, if the fire is forgotten due to forgetting to turn off the grill, the flame in the grill storage 10 rises straight up the flue 600a, and the gas exits from the exhaust port 50. There is a risk of overflowing the body.

[0004] On the other hand, in order to prevent such overflow of the flame, a frame trap provided with a large number of open vents is disposed in the flue to prevent the flame from overflowing out of the body when the object to be ignited is ignited. A technique for preventing this is disclosed in JP-A-9-72546.

In this flame trap, when the combustion exhaust gas is exhausted from the exhaust port 50 to the outside of the body, the heat of the combustion exhaust gas is taken away by the ventilation hole of the flame trap to prevent the propagation of the flame, and the flame is extinguished to overflow the flame. To prevent

[0006]

However, in such a frame trap, it is necessary to reduce the size of the ventilation holes in order to ensure the fire-extinguishing effect. Then, there is a problem that the exhaust gas becomes exhaust resistance and the combustion exhaust gas cannot be discharged smoothly. Then, the gas grill of this invention solves the said subject, and an object is to prevent a flame from overflowing from an exhaust port, without clogging an exhaust flow path by oil, dust, etc.

c, and a flue 62b that makes a U-turn from the communication port 70c to the upper rear of the partition wall 71c and opens to the exhaust port 50 that opens to the upper rear of the body. Therefore, in the third embodiment, the combustion exhaust gas flows into the flue 62 from above the rear part of the grill storage 10 and is guided to the exhaust port 50 in the upper rear part of the body while meandering in the front-rear direction above the grill storage 10. . In addition, this flue 62
The present invention can be applied to a gas grill of a type in which the object to be cooked F is heated by the radiant heat of the burner 40 without keeping the combustion exhaust gas in the grill storage 10. In this case, since the depth direction of the grill storage 10 is usually longer than the height direction, only the meandering in the front-back direction can sufficiently increase the length of the flue 62. Therefore, even if the fire is ignited in the grill storage 10, the flame will
Since it cannot reach zero and does not overflow outside the body, the safety of the gas grill can be improved.

As described above, according to the gas grill of the present embodiment, even if a fire is ignited in the grill chamber, the flue itself will meander and be long, so that it is extremely safe to prevent the flame from overflowing outside the body. High in nature. In addition, since a small hole or mesh such as a frame trap is not provided, the flue is not clogged with oil, dust, and the like, and the durability is improved as compared with the case where a frame trap is provided. Furthermore,
The meandering flue is composed of partition walls 71, 71a, 71 made of plates.
Since it can be formed by providing b, 71c, and 71d, it can be manufactured at a lower cost than providing a frame trap.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention. It is. For example, as shown in FIG. 9, a hole may be provided in the partition wall forming the flue, and a part of the combustion exhaust gas may pass through the hole to short-circuit the flue, thereby reducing the exhaust resistance.
