Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas griller for grilling meat, fish, vegetables, etc.

In this type of roaster, it is desirable that the temperature distribution on the heating surface be uniform in order to prevent uneven roasting and ensure a good cooking finish.

Conventional gas grills have been equipped with a mechanism to modify the combustion flame or have an intermediate heating material interposed in order to equalize the temperature distribution, but the structure is complicated and This makes it possible to improve the uniformity of temperature distribution, but it also causes a lot of heat loss, which was one of the causes of reduced thermal efficiency. Furthermore, when combustion tubes having jet ports at a certain angle with respect to the axis of the combustion tube are installed opposite each other, a portion is formed where the combustion flame does not reach even if they are oriented in the same direction, causing uneven burning. The present invention was constructed in view of such points,
This is a gas roaster in which straight combustion tubes are installed in parallel inside the vessel, and the temperature distribution on the heating surface is made uniform with a simple structure. That is, on one side of a straight combustion tube, an ejection port is bored at a certain angle to a line perpendicular to the axis of the combustion tube, and this combustion tube is installed parallel to both sides of the vessel. , the jet ports are aligned in the horizontal direction and opposed horizontally or slightly upward in the vertical direction. The present invention will be explained in detail below based on embodiments shown in the drawings.

The combustion tube 1 has a straight cylindrical shape and has jet ports 2, 2, . . . bored therein at predetermined intervals on one side thereof.

This combustion tube 1 is limited to a cylindrical shape as long as it is straight, but may be in the shape of a rectangular cylinder. The jet ports 2, 2, . Spout 2 shown in the drawing
, 2... are rectangular, but are not limited to this embodiment, and may be circular, for example, as long as they have a certain angle θ. In the case of a vertically elongated shape such as the embodiment shown in the drawings, the effects of the present invention can be enhanced by slightly tilting it in the vertical direction. The container body 3 is made by bending a metal plate such as stainless steel, and is provided with a drawer-shaped saucer 31 at the bottom to hold water and to store dripping liquid and sauce. Projections 32, 32 are provided toward the top, on which a canopy 5 having a hot opening 4 can be placed. The combustion tubes 1, 1 are installed in parallel on both sides inside the vessel body 3, but there are pedestals 33 extending into the vessel body 3 on both sides of the intermediate part, approximately in the middle of the vessel body 3; It is now supported by 33. Further, secondary air inflow paths 34, 34 are provided from the sides of the vessel body 3 toward the combustion tubes 1, 1. Vessel 3
The ejection ports 2, 2 of the combustion pipes 1, 1 installed inside the
As shown in FIGS. 3 and 5, they are aligned with each other in the horizontal direction and are opposed horizontally or slightly upward in the vertical direction. If the directions of the jet ports 2, 2 do not match in the horizontal direction as shown in FIG. 4, no combustion flame will be formed in the area C surrounded by the dotted line.
It is necessary to match in the horizontal direction. This direction does not have to match exactly, but it is sufficient if the directions roughly match. To use this gas grilling device, first, gas is supplied from the gas supply pipe 6 to the combustion pipes 1, 1 and ignited, and then the cooking ingredients 8 are placed on the pedestals 7, 7 provided on the canopy 5 and roasted. Bake. At this time, the hot opening 4 of the canopy 5 becomes the heating surface, and the combustion tube 1
, 1 are horizontal or slightly upward in the vertical direction, and secondary air is introduced from the side of the vessel 3, so the combustion flame is approximately horizontal. The jet ports 2, 2 of the left and right combustion pipes 1, 1...
... are the same in the horizontal direction, so the combustion flames are formed parallel to the left and right, and the combustion flames on the heating surface are uniform.
There will be no uneven combustion. Nozzles 2, 2 of combustion pipes 1, 1...
When ... is provided in a vertically elongated shape as shown in the figure,
Since the horizontal value of the combustion flame can be made large, the effect of uniformizing the temperature distribution on the heating surface can be improved. Furthermore, the present invention allows fine adjustment of the temperature on the heating surface compared to the conventional method in which straight combustion tubes are installed in parallel and the jet ports are opposed to each other in a direction perpendicular to the axis of the combustion tube. become.

That is, in the conventional case, as shown in FIG. 5, the length of the distance D between both combustion tubes was the limit for combustion flame formation, but in the present invention, the combustion flame can be formed up to the distance shown by E. Since the length of the combustion flame can be finely adjusted in the present invention even if the same adjusting device is used, fine adjustment of the temperature on the heating surface becomes easier. As described above, according to the present invention, it is possible to equalize the temperature distribution on the heating surface with an extremely simple structure, prevent uneven roasting, and achieve a good cooking finish. It has the effect of allowing fine adjustment.
