Description

[Detailed description of the invention] <Industrial application field> This invention relates to a charcoal-fired smokeless roaster.

<Conventional technology> The conventional technology for charcoal-fired smokeless roasters is JP-A-Sho.
There are Publication No. 64-80320 and Publication No. 11150 of Japanese Utility Model Application No. 64-11150, which describe the use of an electric fan to promote ignited charcoal using the wind sent by the fan. This equipment requires installation on each roaster, making the equipment expensive, and there is also the problem that oil scattered during cooking may adhere to the equipment, causing malfunctions or not operating smoothly. Therefore, the applicant
In No. 245230, the forced suction flow from the exhaust duct is used to promote the ignition of a charcoal fire, and once the charcoal fire has started, the charcoal pot casing is rotated to switch to atmospheric circulation to maintain the charcoal fire state. We proposed a charcoal-fired smokeless roaster.

<Problem to be solved by the present invention> However, Japanese Patent Application No. 1-245230 discloses a method for installing a charcoal pot casing on a gas burner accommodating part (square tube part) which is placed between the window holes in the side body of the outer casing. Because the charcoal pot casing is placed directly on top of the charcoal pot, there are two issues: the charcoal pot casing cannot rotate smoothly, and the switching hole in the charcoal pot casing makes it difficult to switch between the intake air flow and atmospheric flow passages. . The present invention attempts to solve this problem.

<Means for solving the problem> The present invention has a rectangular tube section with an open top surface through which air flows between window holes in the side body of the outer casing, which is connected to an exhaust duct and through which a forced intake flow flows. A charcoal pot casing having a plurality of switching holes on the bottom surface is placed on the rectangular tube part, and by rotating the charcoal pot casing, the switching holes are switched to either the forced intake flow or the atmospheric flow so that they face each other. In a smokeless charcoal roaster,
A disk provided with forced intake flow holes and atmospheric air circulation holes is mounted on the rectangular tube, and an annular rail with a stopping concave portion is folded up on the outer periphery of the disk, and is placed on the disk. The charcoal pot casing is placed on top of the charcoal pot casing, and a roll is attached to the outer surface of the charcoal pot casing to fit into the annular rail and lift and rotate the charcoal pot casing.

<Operation> At the point where the charcoal on the trivet in the charcoal pot is ignited, the charcoal pot casing is rotated by the rotation of the roll so that the switching hole directly faces the forced intake flow hole provided in the disk, and the outer casing is turned. Apply the ignited charcoal to the forced intake air flowing inside to promote charcoal fire, and once the charcoal fire has started, rotate the charcoal pot casing again so that the switching hole faces the circulation hole through which air circulates, and then start the charcoal fire. It perpetuates the outbreak.

<Example> Examples will be described below based on the drawings.

The lower part of an outer casing 1 whose upper surface is open is tapered and connected to an exhaust duct 2. Outer casing 1
When the internal exhaust duct 2 is operated, a forced intake flow of the atmosphere flows from the top to the bottom, creating a negative pressure on the duct side. Window holes 3a and 3b are provided at two relative points in the middle of the side body of the outer casing 1, and a rectangular tube portion 4 with an open upper surface is installed facing upward between the window holes.
Atmospheric air flows naturally inside the rectangular tube portion 4. A gas burner 5 is installed in the center of the rectangular tube part 4.
is installed, and 5a is a handle for operation exposed outside the outer casing. On one side of the gas burner 5, an elevating member 6 is disposed with an upper surface having a low slope and moving back and forth. 6a is an exposed operating lever. A disk 7 is mounted on the rectangular tube part 4 in the outer casing 1 with the middle part of the bottom surface facing it. Then, the charcoal pot casing 7a is placed on the disk 7. Reference numeral 7b denotes a charcoal pot, with center holes 8a and 8b provided in the center of the bottom of each pot, through which a tinder tube 9 connected to the gas burner 5 is passed. The crater tube 9 has an inner tube 9a connected to the gas burner 5 and an outer tube 9b that moves up and down.
A part of the lower end of the outer cylinder 9b is placed on the elevating member 6 so that it can be moved up and down as the elevating member 6 advances and retreats. In addition, the upper end of the outer cylinder 9b is closed and a number of small craters 9c are provided on the side.
The trivet 10 is fitted at the position below c. 10a
is a ventilation hole installed in the trivet. There are two switching holes 1 facing each other on the outer periphery of the bottom of the charcoal pot casing 7a.
1a and 11b are provided. The width of the switching hole in the circumferential direction is somewhat narrower than the width of the rectangular tube portion 4. A small hole 12 is provided around the bottom of the charcoal pot 7b at a position that does not overlap the switching holes 11a, 11b.

Therefore, the disk 7 is provided with circulation holes 13a and 13b through which the atmosphere flows in the upper part of the square tube part 4, and circulation holes 14a and 14b for the intake air flow from the exhaust duct 2 are provided at diagonal points outside the square tube part 4. Further, an annular rail 15 is provided by folding up the outer periphery, and a total of four recesses 16 for stopping are provided on the rail 15 at positions symmetrical to each of the holes.
has been established. In other words, the recesses 16 are provided at intervals of 90 degrees. The charcoal pot casing 7a has four rolls 17 attached to the outside that rotate while fitting into the annular rail 15, and when each roll 17 falls into the recess 16, the bottom surface of the charcoal pot casing 7a moves into the disk 7. in contact with the concave portion 16
When going outside, it floats away from disk 7.

The anthracite roaster constructed as described above is installed under the yakiniku table 19 by fitting the bent outer part of the upper end of the outer casing 1 into the mounting hole 18, and has the intake hole 2 inside.
The space between the outer casing 1 and the charcoal pot casing 7a is covered by mounting the top plate 21 which has a chevron-shaped ring shape with 0 surrounding it.

Normally, the charcoal pot casing 7a is rotated together with the roll 17 by pushing the top plate 21, and the state shown in FIG.
11b is in contact with atmospheric circulation holes 13a and 13b provided above the rectangular tube portion 4 of the disc 7, and when igniting the charcoal on the trivet 10 and promoting its combustion, the charcoal pot casing 7a is rotated 90 degrees to switch the switching holes 11a and 11b to the forced intake flow holes 14a and 14b of the disk 7, so that the forced intake flow flowing inside the outer casing 1 is applied to the ignited charcoal to promote ignition. When the temperature reaches a temperature sufficient for yakiniku cooking, the charcoal pot casing 7a is rotated 90 degrees again and allowed to circulate in the atmosphere to maintain the temperature.

<Effects of the invention> As described above, the present invention places a disk on a rectangular tube, folds an annular rail with a stopping recess on the outer periphery of the disk, and attaches the disk to the outside of the charcoal pot casing. Since the attached rolls are fitted, the charcoal pot casing smoothly floats up and rotates as the rolls rotate. Further, since the roll falls into the stopping recess and stops, the switching hole of the charcoal pot casing can be reliably switched to directly face each of the flow holes on the disc.
