Abstract
Description
[Technical field]
[0001] This invention relates to a charcoal grill. [Background technology]
[0002] Diatomaceous earth charcoal grills, which have dominated the market up until now, tend to absorb water and other liquids, which causes the body to deteriorate quickly, making it take a long time to heat up, and resulting in poor combustion efficiency. [Prior art documents] [Patent documents]

[0005] To improve space efficiency and combustion efficiency by using a new material as a base to replace diatomaceous earth charcoal grills, the combustion efficiency of which decreases when the grill absorbs liquid such as water, as a problem to be solved by this invention. [Means for solving the problem]
[0006] In order to prevent unevenness in the combustion temperature, the base is made of water-resistant ceramic to ensure stable combustion, and by having multiple square furnaces, sufficient combustion space is ensured, and by installing multiple ventilation holes, temperature can be adjusted frequently to increase combustion efficiency. Effect of the Invention
[0007] Unlike diatomaceous earth charcoal grills, which lose their combustion efficiency when they absorb water or other liquids, the body of this grill is made of water-resistant ceramic, which makes it possible to prevent uneven combustion temperatures. Furthermore, by exposing a portion of the stove, heat from the main body is released to the outside, preventing the temperature from rising excessively. By opening and closing the multiple ventilation opening bars, the temperature can be adjusted frequently, and since there are multiple furnaces, sufficient combustion space is secured, improving combustion efficiency.

[0009] Figure 1 is a perspective view of the ceramic charcoal grill body, with 1 being the ceramic charcoal grill body and 2 being the inside of the body. When viewed from above, the ceramic charcoal grill body is square, with its outer edge formed by four sides and corners. This allows for efficient use of space for grilling ingredients. The body is also made of a ceramic material that is resistant to water.
[0010] Figure 2 is an assembly diagram of a ceramic charcoal grill, with 3 being the exposed part, 4 being the vent opening and closing bar, 5 being the installation hole for the grill with legs, and 6 being the legs of the grill. The ceramic body 1 is exposed in the exposed part 3 in order to allow heat to escape and prevent injuries such as burns caused by the surface temperature of the metal plate rising too high.
[0011] The inside of the main body 2 has multiple furnaces, and fuel is placed inside the furnaces to be burned. The vent opening and closing bar 4 has multiple windows, and the temperature inside each furnace can be adjusted by sliding the knob. The inside of the main body 2 has multiple furnaces, and by adjusting the temperature inside each furnace, each of the multiple furnaces can generate a different amount of heat. In addition, when one of the multiple furnaces is not burning, it can be used in a wide variety of ways, such as storing fuel such as charcoal.
[0012] Figure 3 shows a net with legs 6 that is installed on top of the main body of a square ceramic charcoal grill, with three legs on each side when viewed from the short side. The net is fixed by fitting the legs of symbol 6 into the holes of symbol 5, as shown in the completed diagram in Figure 4, and the net itself is stabilized.
[0013] The present invention is not limited to the above-mentioned embodiment, but can be widely applied. For example, the present invention is applicable to a charcoal grill having three or more burners, and the scope of application of the present invention also includes cases where a charcoal grill body having an outer edge without corners is used.
