Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a portable and disposable roaster that is used, for example, when barbecuing outdoors.

(Prior art) The latest known conventional simple roaster of this type is the one disclosed in Utility Model Application No. 61-49201, which is characterized by the use of nonflammable sheet members. The bottom of the box-shaped body is filled with igniting material and fuel charcoal in a layered manner, and a grit member is stretched over the fuel charcoal. Or perhaps even more opening/closing windows.

(Problems to be solved by the invention) The conventional example described above is constructed so that a closing window is provided in the side wall of the box-shaped main body to introduce wind and improve the combustibility of the thermal coal. However, since the inside of the box is filled with ignition material and fuel charcoal in layers, the ventilation inside the box is obstructed, and although the effect of increasing combustibility near the opening/closing window is recognized. It is not sufficient to increase the combustibility of the entire area inside the box-shaped body, and the firepower is uneven in the area. There is also the problem that ash builds up due to the combustion of thermal coal, which obstructs ventilation. Furthermore, since the ignition material is placed in direct contact with the bottom of the box-shaped body, there is a problem in that the bottom of the ignition material has poor air permeability and the ignition material itself tends to cause incomplete combustion.

The purpose of the present invention is to solve this problem and provide a new simple roaster with better combustibility.

(Means for Solving the Problems) The simple roaster of the present application devised to achieve the above object has an open top surface and a firepower adjustment port and ignition port provided at required positions along the bottom surface of the side wall. The case body is made of thin metal sheet, and has multiple wide bent parts that bulge downward. A metal mesh partition placed on the bottom of the case body with both ends facing the firepower adjustment ports, an ignition material placed on the top surface of the bent portion of the metal mesh partition, and the ignition material. solid fuel placed on top of the solid fuel and metal net-like partition, and a net for placing cooking ingredients that is placed over the solid fuel and whose peripheral edge is fixed to the upper opening edge of the case body. It consists of.

(Embodiment) The illustrated embodiment of the present invention has a flange 2 having an opening on the upper surface and a groove 1 opening inward at the edge of the opening.

7'' and 7, and on the bottom surface 4 of the case body 8 so that both ends of the space 10 between the bent parts 9 and 9' face the firepower adjustment ports 6 and 6' of the case body 8, respectively. The metal net-like partition 11 to be placed has a three-dimensional shape, and the fuse strings 12, 12', 12'',
12 and impregnated with a well-known solvent with good ignitability, the bent portions 9,
Ignition materials 13, 13', 13'', 13 are housed and installed at both ends of the upper surface of the metal mesh partition 11, and ignition materials 13, 13', 13'', 13 are placed on the upper surface of the metal mesh partition 11.
The charcoal 14... placed so as to cover the charcoal 14... is placed over the charcoal 14... and its peripheral edge is inserted into the groove 1 of the flange 2 at the upper opening edge of the case body 8. It consists of a metal mesh body 15 for placing cooking ingredients that is integrally fixed.

Note that 16 in the figure is a protrusion 16 of a required height provided on the bottom 4 of the case body 8. This protrusion has the function of preventing the metal mesh partition 11 from shifting, but the metal mesh partition 11 is placed on this protrusion 16 so that the metal mesh partition 11 and the bottom surface 4 of the case body 8 A slight gap may be formed in between. In addition, the depth of the spaces 10, 10', 10'' on the lower surface of the metal mesh partition 11 is set to a sufficient depth so that even if ash from combustion of the charcoal 14 accumulates, it will not become clogged. has been done.

In this invention, the material and shape of the case body, the position and number of the firepower adjustment port and ignition port, the shape of the hollow space on the lower surface of the metal mesh partition, the position and number of bent parts, the type of ignition material and solid fuel, The method of fixing the net to the case body is not limited to the above-mentioned embodiments, and can be developed in various ways.

(Operations and Effects) The structure of the present invention is as described above. First, a well-ventilated space is provided at the bottom of the case body with a metal mesh partition that is not filled with anything. The air sent through the adjustment port is not obstructed by anything and spreads throughout the entire area inside the case body, improving combustibility evenly throughout the entire area. Furthermore, by setting the depth of the cavity to a dimension with sufficient margin, the problem of obstructing ventilation due to stacking of ash can be solved. Furthermore, since the ignition material is placed on the top surface of the metal mesh partition rather than directly on the bottom of the case body, the ventilation at the bottom of the ignition material is improved, which reduces the problem of incomplete combustion of the ignition material itself. is also resolved. The amount of ventilation can be controlled by opening and closing the lid as well as the heat adjustment port. Therefore, the simple roaster of the present invention not only has improved air permeability as a whole, but also allows the heating power to be adjusted by controlling the amount of ventilation, so it has the effect of greatly improving combustion efficiency compared to conventional products.
