TECHNICAL FIELD OF THE INVENTION
The present invention relates to a smokeless roaster for burning charcoal, which prevents scattering of ash generated when burning charcoal.
[0002]
[Prior art]
Conventionally, in such a smokeless roaster for charcoal grilling, an inner box is disposed inside an outer box disposed below a table, and a rostrum and a grill are placed above a trumpet-shaped charcoal pot disposed in the inner box. Place a food mounting body such as, and form a lower opening at the bottom of the charcoal pot, and install a grate for placing charcoal inside the bottom, air sent at the time of ignition to charcoal, It can be seen that the material is supplied into the charcoal pot through the lower opening of the charcoal pot.
[0003]
[Problems to be solved by the invention]
However, in the above prior art, the ashes generated during the burning of charcoal fall down on the inner surface of the steeply inclining charcoal pot and then slide down and accumulate on the outer periphery of the soum of the charcoal pot. Since air is supplied from the lower opening into the charcoal pot, if the amount of air required for burning charcoal increases, the flow velocity inevitably increases, and as a result, the ash that accumulates on the sana becomes There were issues that had to be solved, such as flying soaringly and scattering into the room.
[0004]
[Means for Solving the Problems]
The present invention is based on the above conventional technology, in view of the problem that the ash soars and scatters in the room, the storage tubular portion is formed to rise from the outer peripheral portion of the lower opening of the outer box disposed at the lower portion of the table, A drain pan formed in a ring shape and raised at the center thereof to form an outer cylindrical portion having an upper opening is provided below the inner box provided inside the outer box. In addition, a ventilation hole is formed in the storage cylinder and the outer cylinder, a lower opening is formed in the bottom of the charcoal pot placed in the inner box, and a sana is mounted on the bottom in the charcoal pot. And a feed fan connected to an outer box provided below the outer box, an inner box is provided in the outer box, and the inner box is provided with an outside air introducing means partitioned from the inner space of the outer box. A gas / primary air supply unit is provided in the storage cylinder of the outer box, The burner main body at the upper end of the supply unit is arranged on the housing cylinder part, the lower part penetrates the upper part of the inner box, the air intake and the gas intake are formed at the lower end, and the gas supply pipe is connected to the gas intake. When the charcoal is ignited, the feed fan is used to feed the inside of the outer box, the inside of the housing tube, the ventilation hole of the housing tube, the space between the housing tube and the outer tube, and the side of the outer tube. The air is sent into the inner box through the ventilation hole and is sent into the charcoal pot from the lower opening of the charcoal pot. By forming an air inflow hole in the lower part of the side, the outside air sent into the inner box from the ventilation hole on the side of the outer cylindrical portion is diverted to the lower opening of the coal jar and the air inflow hole, Reduce the amount of supply from the lower opening and increase the upward airflow by the lateral airflow from the air inlet. To suppress the riding ash in the manner not more Maiagara, to solve the above-mentioned problems.

【The invention's effect】
In short, according to the present invention, the accommodating cylindrical portion 14 is formed so as to rise from the outer peripheral portion of the lower opening 10 of the outer box 5 disposed at the lower portion of the table 1, and is formed at the lower portion of the inner box 6 provided inside the outer box 5. A drain pan 17 having a ring-like shape, a central portion of which is raised to form an outer tubular portion 18 having an upper opening, and the outer tubular portion 18 is inserted into the containing tubular portion 14, and , 19, 19a... Are formed in the portion 14 and the outer cylindrical portion 18, and a lower opening 27 is formed in the bottom of the charcoal vat 26 placed in the inner box 6, and the charcoal vat 26 is formed. Since the SANA 32 is placed on the bottom of the inside, the air sent into the housing cylinder portion 14 is sent into the inner box 6 through the ventilation holes 15, 15a..., 19, 19a. Since it is meandered by passing through the lower opening 27 and into the charcoal vat 26, the Since the momentum at the time of being sent into the interior of the coal jar 6 can be reduced, the ash that has accumulated at the bottom of the coal jar 26 can be prevented from rising, and scattering into the room can be prevented as much as possible. Since the supply fan 46 is connected to the outer box 36 provided below the box 5, it is possible to reliably supply a necessary amount of air into the coal jar 26.
In addition, the inner box 37 is provided in the outer box 36, and the inner box 37 is provided with the outside air introducing means separated from the inner space of the outer box 36, so that air can be reliably introduced into the inner box 37 from the outside. The gas / primary air supply part 42 is disposed in the storage cylinder part 14 of the outer box 5, and the burner main body 45 provided at the upper end of the gas / primary air supply part 42 is connected to the storage cylinder part. 14, the lower part of the inner box 36 penetrates the upper part of the inner box 36, the lower end of which forms an air inlet 41 a and a gas inlet 41 b, and the tip of a gas supply pipe 44 is inserted into the gas inlet 41 b. Therefore, the air required for gas combustion can be reliably drawn from the inner box 37 separately from the air supplied to the coal jar 26 side, so that the gas can be completely burned.
[0016]
Since the air inlet holes 30, 30a... Are formed in the lower part of the side of the coal jar 26, the air sent into the inner box 6 is diverted to the lower opening 27 of the coal jar 26 and the air inlet holes 30, 30a. By doing so, the supply amount from the lower opening 27 can be reduced, so that the rising of the ash can be further suppressed, and the horizontal airflow from the air inlet holes 30, 30a. As a result, ash on the ascending airflow can be suppressed, so that the effect of preventing ash from scattering into the room can be further improved, and air is supplied not only from below but also from the side. Because of this, charcoal can be ignited evenly.
[0017]
A baffle plate 20 projecting outward and obliquely downward is provided around the outer periphery of the upper portion of the outer cylindrical portion 18, so that the air sent into the inner box 6 is once directed downward to further increase the momentum. It is possible to sharpen the air, and it is easy for air to flow in from the air inlet holes 30, 30a..., And it is possible to improve the ignition efficiency of the charcoal and to shorten the ignition time. It is.
