Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a charcoal-fired smokeless roaster.

<Prior art> This type of prior art includes Japanese Patent Application Laid-Open No. 64-80320 and Japanese Utility Model Application No. 64-11150.

<Problems to be Solved by the Present Invention> All of the above-mentioned conventional technologies are equipped with an electric fan, and use the wind sent by the fan to quickly bring the ignited charcoal to a state where it can be grilled. This equipment makes the roaster expensive, and there is also the problem that it does not operate smoothly due to malfunctions caused by splashing of oil etc. The present invention attempts to solve such problems.

<Purpose of the Invention> The present invention focuses on the fact that a charcoal-fired smokeless roaster has duct equipment and sucks the smoke generated by grilled meat to make it smokeless. The purpose is to accelerate the ignition of charcoal.

<Structure of the Invention> The present invention provides an outer casing that is connected to an exhaust duct so that the intake air flows inside when the duct is operated, and a window hole provided in the side body of the casing to allow air to flow through the outer casing. A gas burner accommodating part with an opening on the top surface that allows the flow to flow, a charcoal pot in which a tinder tube with a trivet is loosely fitted onto the accommodating part, and a charcoal pot casing containing the charcoal pot are rotatably placed on the charcoal pot. The charcoal-fired smokeless roaster is characterized in that a hole provided in the bottom plate of the casing is switched to face the top of the housing part and the outside of the housing part, so that an intake air flow and an atmospheric flow are selectively supplied to the trivet. .

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

The lower part of the outer casing 1 having an open upper surface is narrowed 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 top to 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 square gutter-shaped gas burner accommodating portion 4 is installed facing upward between the window holes. A natural flow of air flows through the housing section 4. A gas burner 5 is installed in the center of the housing section 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. Inside the outer casing 1, a charcoal pot casing 7a is arranged so that the middle part of the bottom surface is placed on the accommodating part 4. Reference numeral 7b denotes a charcoal pot, with center holes 8a and 8b provided in the center of each bottom plate, through which a nozzle tube 9 connected to the gas burner 5 is passed.
The crater tube 9 is an inner tube 9a connected to the gas burner 5.
The outer cylinder 9b is formed by an outer cylinder 9b that moves up and down.
A part of the lower end is placed on an elevating member 6 and is moved up and down as the elevating member 6 advances and retreats. Further, the upper end of the outer cylinder 9b is closed, and a number of small nozzles 9c are provided on the side surface, and a trivet 10 is fitted at a position below the nozzles 9c. 10a is a ventilation hole provided in the trivet. Two opposing holes 11a and 11b are provided on the outer periphery of the bottom plate of the charcoal pot casing 7a.
The width of the hole in the circumferential direction is somewhat narrower than the width of the accommodating portion 4. The bottom plate of the charcoal pot 7b has a hole 11a,
A small hole 12 is circumferentially provided at a position that does not overlap 11b.

The anthracite roaster configured as described above is installed under the yakiniku table 14 by fitting the outer bent portion of the upper end of the outer casing 1 into the mounting hole 13.
By mounting the top plate 16, which has a chevron-shaped ring shape with an intake hole 15 around it, it covers the space between the outer casing 1 and the charcoal pot casing 7a, and the charcoal pot casing 7a can be rotated by pushing the top plate 16 around. The holes 11a, 1 made in the bottom plate by moving
1b is switched between the top of the housing part 4 and the outside thereof. In the figure, numeral 17 is a lid that is removably mounted on the charcoal pot 7b.

<Function> In the present invention, the holes 11a and 11b provided in the bottom plate of the charcoal pot casing 7a are positioned above the housing part 4, and the gas burner 5 is operated to ignite the charcoal A on the trivet 10, so that the charcoal A is At the point where the charcoal pot casing 7a is ignited, the top plate 16 is pushed and turned.
The outer casing 1 is rotated to shift the extraction holes 11a and 11b to the outside of the side surface of the housing part 4, that is, to the position shown in FIG.
It exposes the body to a forced inspiratory flow. The charcoal A is rapidly ignited by the intake air flowing from top to bottom, making it ready for grilling.

When such a state is reached, rotate the charcoal pot casing 7a together with the top plate again to remove the extraction hole 11.
a and 11b are placed on the housing part 4, and the combustion state of the charcoal is maintained in a substantially constant state by atmospheric flow. If the firepower is strong, the lifting member 6 is moved back using the lever 6a, and the trivet 10 is adjusted to descend together with the outer cylinder 9b. After use, the trivet 10 is lowered to the lowest position, the ventilation holes and small holes are closed, and the extinguishing lid 17 is placed over the fire to extinguish the fire.

<Effects of the Invention> The present invention provides a gas burner accommodating portion in which a natural flow of air flows between the outer casing and the side body portion of the casing, which are connected to the exhaust duct and configured to allow intake air to flow therein. The holes provided in the bottom plate of the charcoal pot casing were made to face the above-mentioned intake air flow and the natural flow of the atmosphere.
The charcoal on the trivet has the effect of being able to be heated rapidly by receiving the intake air flow, and the charcoal that has been lit can be sustained for a long time in the natural flow of the atmosphere. Since the charcoal is promoted using the intake air flow of the exhaust duct, no other equipment dedicated to blowing is used during the charcoal generation process, which reduces the cost of the device and prevents the charcoal generation from being delayed due to equipment failure. This has the effect of eliminating the need for professional maintenance of the equipment.

Since the elevating member moves the trivet with charcoal on it and the tinder tube up and down, the firepower can be adjusted by changing the distance from the grilled meat without burning the charcoal, and there is no waste of charcoal. This produces the effect that it can be burned to save fuel costs.
