Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a smokeless roaster for charcoal grilling that prevents ash scattering during charcoal combustion.
[0002]
[Prior art]
Conventionally, in such a smokeless roaster for charcoal grilling, an inner box is disposed inside an outer box disposed below the table, and a rooster and grill net are disposed above the trumpet-shaped charcoal basket disposed in the inner box. Etc., placing a food placing body such as, forming a lower opening in the bottom of the charcoal, and installing a grate for placing charcoal inside the bottom, the air sent when igniting the charcoal, It can be seen that what is supplied into the anthrax through the lower opening of the anthrax.
[0003]
[Problems to be solved by the invention]
However, in the above prior art, the ash generated during the charcoal combustion falls on the inner surface of the coal annulus steeply inward, slides down, and accumulates on the outer periphery of the anthropomorphic anthrax. Since air is supplied from the lower opening into the anthrax, if the amount of air necessary for charcoal combustion increases, the flow rate will inevitably increase, and as a result, the ash accumulated on the sana will There was a problem that had to be solved, such as rushing up and splashing into the room.
[0004]
[Means for Solving the Problems]
The present invention is based on the above prior art, and in view of the problem that ash soars and scatters in the room, the storage cylinder is raised from the outer periphery of the lower opening of the outer box disposed in the lower part of the table, In the lower part of the inner box provided inside the outer box, there is provided a drain pan which is formed in a ring shape and its central part is raised to form an outer cylindrical part having an upper opening, and the outer cylindrical part is placed inside the accommodating cylinder part. In addition, a vent hole is formed in the housing cylinder part and the outer cylindrical part, a lower opening is formed in the bottom part of the anthrax placed in the inner box, and a sana is mounted on the bottom part in the anthrax. And connecting an air supply fan to an outer box provided below the outer box, and providing an inner box in the outer box, and an outer air introducing means partitioned from the inner space of the outer box in the inner box. A gas / primary air supply section is provided in the housing cylinder of the outer box, and the gas / primary air The burner body at the upper end of the supply part is arranged on the housing cylinder part, the lower part is passed through the upper part of the inner box, the air inlet and the gas inlet are formed at the lower end part, and the gas supply pipe is provided at the gas inlet When the charcoal is ignited, the feeding fan is used to feed the inside of the outer box, the inside of the housing cylinder, the ventilation hole of the housing cylinder, the space between the housing cylinder and the outside cylinder, and the side of the outside cylinder. Air is sent into the inner box through the ventilation holes and sent into the anthracite from the lower opening of the anthracite, so that the air currents meander and the momentum is reduced. By forming the air inflow hole in the side lower part, the outside air sent into the inner box from the side air hole of the outer cylindrical part is shunted to the lower opening of the anthrax and the air inflow hole, The amount of supply from the lower opening is reduced, and the upward airflow is a lateral airflow from the air inlet hole. To suppress the riding ash in the manner not more Maiagara, to solve the above-mentioned problems.

[0015]
【The invention's effect】
In short, in the present invention, the housing cylinder portion 14 is formed upright from the outer peripheral portion of the lower opening portion 10 of the outer box 5 disposed in the lower portion of the table 1, and is formed in the lower portion of the inner box 6 provided inside the outer box 5. The drain pan 17 is formed in a ring shape and its central portion is raised to form an outer cylindrical portion 18 having an upper opening, and the outer cylindrical portion 18 is inserted into the accommodating cylindrical portion 14 and the accommodating cylinder. .., 19, 19 a... Are formed in the bottom portion of the anthrax 26 placed in the inner box 6. Since the sana 32 is placed on the bottom of the inside, the air sent into the housing cylinder part 14 is sent into the inner box 6 through the vent holes 15, 15a, ..., 19, 19a ... Since it meanders by passing through the lower opening 27 and being sent into the anthrax 26, the momentum when it is fed into the anthrax 26 can be cut off, so that it accumulates at the bottom of the anthrax 26. As a result, it is possible to prevent the ash from rising, and to prevent scattering to the inside as much as possible, and because the feed fan 46 is connected to the outer box 36 provided below the outer box 5, The air can be supplied reliably and in the required amount.
In addition, the inner box 37 is provided in the outer box 36, and the inner box 37 is provided with an outside air introduction means that is partitioned from the inner space of the outer box 36. The gas / primary air supply unit 42 is disposed in the storage cylinder 14 of the outer box 5, and the burner body 45 provided at the upper end of the gas / primary air supply unit 42 is stored in the storage cylinder 14 and the lower part is made to penetrate the upper part of the inner box 36, the air inlet 41a and the gas inlet 41b are formed at the lower end thereof, and the tip of the gas supply pipe 44 is inserted into the gas inlet 41b. Therefore, air necessary for gas combustion can be reliably drawn from the inside of the inner box 37 separately from the air supplied to the anthrax 26 side, so that the gas can be completely burned.
[0016]
Since the air inflow holes 30, 30a... Are formed in the lower part of the side of the anthrax 26, the air sent into the inner box 6 is divided into the lower opening 27 of the anthrax 26 and the air inflow holes 30, 30a. As a result, the amount of supply from the lower opening 27 can be reduced, so that the ash can be further prevented from rising, and the airflow from the air inflow holes 30, 30 a. As a result, it is possible to suppress the ash riding on the ascending current, so that the effect of preventing the 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]
Since the baffle plate 20 that protrudes outward and obliquely downward is provided around the upper outer peripheral portion of the outer cylindrical portion 18, the momentum is further increased by directing the air sent into the inner box 6 once downward. It can be cut and air can easily flow from the air inflow holes 30, 30a, etc., so that the charcoal ignition efficiency can be improved and the ignition time can be shortened. It is.
