[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is applied to a meat / vegetable baking machine, in which a burner pipe provided with a large number of gas ejection combustion holes is arranged substantially horizontally in the gas combustion chamber, and each ejection combustion hole is directed above the combustion chamber inner surface. Even if the burner cover is installed in parallel and the burner cover is installed in parallel above the pipe, the heating temperature of the entire surface of the baking plate could not be made almost uniform, and good uniform heating can be performed.

[Prior art]

 A burner plate d of a conventional griller for meat, vegetables, etc. is provided with a burner pipe b having a large number of gas ejection combustion holes c formed inward of the gas combustion chamber a, and a burner cover above the bipe b. The substantially horizontal arrangement is disclosed in Japanese Utility Model Publication No. 2-49483. The outline is as shown in FIG. However, according to the above configuration, since the heating temperature of the baking plate d is not averaged, the reason for this is explored.In the burner pipe b, the downstream end of the combustion gas is closed and the combustion flame is inclined in the downstream direction, but the downstream It was found that the amount of gas ejected from the gas ejection combustion holes in the end direction was relatively large, the amount of gas ejected in the upstream was smaller, and the fire power was proportional to it.

[0003]

[Problems to be solved by the device]

 However, there are some places that I cannot fully understand, so as shown in FIG. 6, the gas ejection combustion holes c of the horizontally arranged burner pipe b are provided so as to be directed toward the upper inside of the combustion chamber a and the burner pipe b is provided above them. The heating device of the baking plate d was tested by making an experimental device having a horizontal burner cover e arranged in parallel, and as described above, the heating temperature is relatively low in the region I and the average heating region II. , And it was not possible to ameliorate the temperature gradient defect that resulted in Region III where the heating temperature was relatively high. However, when one baking plate d is used by a large number of people at the same time, the temperature gradient described above causes a difference in baking time, which causes an unfairness. . By chance at the end of the test, the temperature gradient could be eliminated by arranging the burner cover e on a slope with the upstream direction of the flow of the fuel gas in the burner pipe b raised. Since this phenomenon is consistent with the problems and objectives of the present invention, most of the tests were repeated to complete the present invention.

[Means for Solving the Problems]

 The meat / vegetable broiler according to the present invention meets the above-mentioned purpose. A burner pipe provided with a large number of gas ejection combustion holes is provided substantially horizontally on the inner surface of the peripheral wall of the gas combustion chamber. Combustion holes are provided under a slanted arrangement that points above the inner surface of the peripheral wall, and a burner cover is installed above the burner pipe so that the upstream of the gas flow is high and slanted, and the burner cover is used for turning. The curvature of the gas combustion flame is changed according to the above-mentioned inclination so that the entire surface of the baking plate is heated to a substantially uniform temperature, and the exhaust combustion flame is discharged from the peripheral edge of the baking plate hanging on the upper opening of the gas combustion chamber. It is what

[0005]

[Action]

 According to the present invention, it is a natural phenomenon that the gas combustion flames generated in the gas ejection combustion holes 12 provided in the burner pipe 11 incline toward the downstream direction of the gas flow. The burner covers 13 and 13 are provided under the inclined arrangement that is directed above the inner surfaces of the peripheral surfaces 3 and 3 of the chamber 1, and above each of the burner pipes 11 and 11 by increasing the upstream of the gas flow to incline. With this configuration, the gas combustion flame hits the lower surface of the burner cover 13 by partially changing the angle and further changes the curvature to heat the baking plate 16, so that the gas combustion flame is heated by the gas combustion chamber 1. Although it is not clear theoretically that it is agitated sufficiently evenly in the inside, the heating temperature gradients of I, II, and III in Fig. 6 are eliminated, and the whole can be heated almost uniformly.
