Abstract

PURPOSE:To make a temperature distribution uniform, by a method wherein a jet nozzle is bored in a direction at a fixed angle with a line meeting at right angles with an axial line of a combustion pipe, and the jet nozzles of the combustion pipes which are in parallel with each other are made to coincide in a horizontal direction with each other and are made to confront horizontally in a vertical direction with each other. CONSTITUTION:For use of a gas combustor, gas is supplied first to a combustion pipe 1 for ignition, then a material 8 to be cooked is placed on a pedestal 7 provided on a canopy 5 for broiling. A jet nozzle 2 of the combustion pipe 1 is either horizontal or turned slightly upward in a horizontal direction, and a burning flame is formed almost horizontally because secondary air is injected into from the side of an instrument 3. Burning flames on both a left and a right sides are formed in parallel with each other, the burning flames on a heating surface are made uniform and uneven broiling is eliminated as the jet nozzles 2 of the left and the right side combustion pipes 1 coincide in a horizontal direction with each other. By this constitution, temperature distribution can be made uniform and uneven broiling can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas grill 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 good cooking results. 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 However, it was not possible to improve the effectiveness of making the temperature distribution uniform, and there was also a large amount of heat loss, which was one of the causes of decreasing 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, if they are oriented in the same direction, a portion where the combustion flame does not pass will be formed, causing uneven burning.

The present invention has been constructed in view of these points, and aims to equalize the temperature distribution on the heating surface with a simple structure in a gas roaster in which straight combustion tubes are installed in parallel inside the container. It is something that That is, on one side of the straight combustion tube, a jet nozzle is oriented at a certain angle with respect to the orthogonal line of the narrow axis of the combustion tube, and this combustion port is installed parallel to both sides of the vessel body. The ejection ports are aligned in the horizontal direction and faced 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), etc. bored at predetermined intervals on one side thereof. As long as the combustion tube (1) is straight, it is not cylindrical and may be rectangular. Combustion tube (1) σ-)
-The spout holes (2), (2)... drilled on the side are
A certain angle (θ) is provided to the orthogonal line (■()) to the axis (A) of the combustion tube (1).The jet nozzle (2) shown in the drawing,
Although (2)... is a rectangle, it is not limited to this embodiment, and may be, for example, circular, with 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 equipped with a drawer-shaped saucer (31) at the bottom to hold water and to store dripping liquid, sauce, etc. Niba vessel body (3) Overhanging part (32) towards the center.

(32) and a canopy (5) having a heating opening (4) above it.
) can be placed. Combustion tube (1).

(1) is installed parallel to both sides of the vessel (3), but is a pedestal that extends toward the inside of the vessel (3) on both sides of the approximately middle part of the vessel (3). (33) and (33). A secondary air inflow path (34), which may be located on the side of the vessel body (3), is directed towards the combustion pipes (1), (1).
, (34) are provided (・ru.

The combustion pipes (1), (17') and the ejection ports (2) installed in the vessel body (3) are connected to each other as shown in Figs. 3 and 5. They are aligned in the horizontal direction and are opposed horizontally or slightly upward in the vertical direction.If the directions of the spout ports (2), (2) do not match in the horizontal direction as shown in Figure 4, Since no combustion flame is formed in the part (C) surrounded by the dotted line, it is necessary to match them in the horizontal direction. Even if the directions do not match exactly, it is sufficient that the directions roughly match.

To use this gas roaster, what is the combustion tube (1,)?
Gas is supplied to (1) from the gas supply pipe (6) and ignited, then the cooking ingredients (8) are placed on the pedestal (7) + (7) set on the canopy (5) and roasted. .

At this time, the hot opening (4) of the canopy (5) becomes the heating surface, and the jet opening (2) of the combustion tube (1,), (1').

(2) ... is placed vertically and horizontally (・
is slightly upward, and secondary air is flowing into the vessel (3).
Since it is fired from the side, the combustion flame is formed almost horizontally,
In addition, the left and right combustion pipes (1), the jet ports (2) of (1), (
2) ... are the same in the horizontal direction, so the combustion flames are formed in parallel to the left and right, the combustion flames on the heating surface are uniform, and there is no uneven combustion.
), if the ejection port <2), (2>...... is vertically elongated and sloped as shown in the figure, the horizontal width of the combustion flame can be widened (formed), so the heating The effect of uniformizing temperature distribution on the surface can be improved.

Furthermore, the present invention allows for fine adjustment of the temperature on the heating surface compared to the conventional structure in which straight combustion tubes are installed in parallel and their jet ports are opposed to the axis of the combustion tube in a +1i angle direction. It becomes possible. That is, in the conventionally known case, as shown in FIG. 5, the length of the gap (1) between both combustion tubes was the limit for combustion flame formation, but in the present invention, the gap shown by E Even if the same adjustment device is used, the length of the combustion flame can be finely adjusted by the present invention, which makes it easier to finely adjust the temperature on the heating surface.

As described above, according to the present invention, it is possible to uniformize 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 finely adjusting the temperature on the heating surface.
