It relates to a charcoal ignition device that is controlled by using it.

[0002]

[Prior art]

 Conventionally, this type of charcoal ignition device is a hollow cylinder as shown in FIG. 5, FIG. 6, and FIG. 7 of the drawings attached to the specification of the present application, for example, as shown in FIG. 3 of Japanese Utility Model Publication No. 2-85901. Charcoal C piled up on a fire bed 2 supported by being mounted on a collar 4 projecting into an inner cavity 3 of a body 1 (a stove) 1 , The gas stove B (FIG. 5) placed on the lower base 7 of the cylinder 1 or the gas burner Ba (FIG. 6) is ignited by the flame of the gas, or as another conventional example, it is fired at another place. There are things such as putting the seed fire charcoal that has caused the fire in a container, inserting it, and igniting it, but this requires labor for transportation, there is a risk of fire spillage during transportation, and The charcoal can be scratched up with fire chopsticks to consume double energy and energy such as arranging the charcoal one by one. There is a drawback that it becomes.

Further, in the structure of the hollow cylindrical body (stove) 1 of the conventional example, an air intake hole 6 for inserting and removing a closing plug 5 is formed below a fire bed (chamber) 2 on which charcoal C is placed. Yes, it is a structure that sends air upward from below to charcoal C by utilizing the convection effect of hot air, and adjusts the amount of air by adjusting the insertion position of the closure plug 5 to adjust the strength of the heat power. Is the current situation.

Therefore, the degree of adjustment of the intensity of the heating power is slow, and it is not appropriate to meet the demand for the rapid change, and the temporal adjustment of the heating power is impossible. Furthermore, in the structure in which the charcoal C of the fuel is piled up and placed on the fire bed 2 locked to the collar portion 4 formed to project into the inner cavity portion 3 of the stove 1, air is fed from below the charcoal C. Because of the structure, it is necessary to separately install an ash receiver 7b for receiving the ash of the burning dust of the charcoal C falling on the base 7 (Fig. 7).

[Problems to be solved by the device]

 Therefore, in the conventional charcoal ignition device of this type described above, the former ignites with the flame of gas, so the troublesome work of drawing the gas pipe supplying the gas around the installation site and the ignition tool for igniting the gas. It is necessary to handle them and the like. Therefore, it is difficult to control the fire power in detail, and by leaving the flame of the gas for making the pilot fire open, the meat itself other than the original purpose is directly burned with the flame of the gas. There are many drawbacks, such as the fact that customers often eat it up, and it takes a long time to bake it, so customers may eat it before it is fully baked. In the latter case, the charcoal is ignited in another place to make a pilot fire, so there is a risk of trouble of transporting the pilot fire and the risk of spilling during the transportation. It had the drawback of requiring double labor and energy such as scratching C.

In any of the conventional examples, the wind is blown up from below the fire bed 2 on which the charcoal C is piled up through the eye of the cage using natural air flow (convection action). Therefore, it is difficult to control the air volume by the closing plug 5, and there is a drawback that it is difficult to respond to a request for a particularly rapid air volume change.

In order to make up for such drawbacks of the conventional ignition device, there is a device that installs a blower device by another blower and blows air for heating power and uses the flow of the air (blast). However, the air was always blown up from above the charcoal C that had been piled up from below the fire bed (chamber) on which the charcoal was placed, through the eye of the cage 2. However, it was difficult to control the strength of the wind power in the ignition device of this structure, and at best, it was only possible to switch between “strong” and “weak”.

Further, there are those that gasify and ignite liquid fuels such as petroleum and kerosene, but there is a drawback that the device becomes bulky, such as replenishment of liquid fuel and the need for a vaporizer.

Therefore, in order to solve the above-mentioned conventional problems, the present invention directly blows the air heated by the hot air heater unit on the charcoal piled up in the inner cavity of the stove to ignite it. Furthermore, by applying an appropriate amount of hot air directly to the charcoal, the ignition and burning of the charcoal can be expanded in a stationary state, and when the heat power suitable for the roasting of meat is reached, the heat power after that and the blowing air blown. By controlling the strength and air flow of the meat, keeping it at a suitable time and for a certain period of time, and keeping it for a certain period of time. It is an object to provide an economical charcoal ignition device that can be easily obtained, and automatically stops all after completion.

FIG. 3 is a perspective view showing a blower and a heater of the present invention with some cutouts cut out, and FIG. 4 is a perspective view of a cage according to the present invention.

Reference numeral 1 is a hollow cylindrical stove made of diatomaceous earth or the like, which is dropped into a mounting hole formed in the center of the table 10 so that the upper surface of the stove 1 and the upper surface of the table 10 are substantially at the same height. In order to coincide with each other, they are placed on the stove base 1c placed on the support frame 13 attached to the table 10 and arranged. A cage 2 serving as a fire is held inside the inner cavity 3 of the stove 1, and charcoal 9 of fuel is stacked and placed on the cage 2. Further, a blow hole 5 for blowing air is formed in the middle of the side wall 1a of the stove 1 above the cage 2.

In the conventional example, as shown in FIGS. 5, 6 and 7, the hollow stove 1 is made of diatomaceous earth or the like, and in order to hold the fire chest 2 in the inner cavity 3, There is a protruding collar 4 that holds the outside of the flat cage 2, but because the material is soft diatomaceous earth, etc., it wears down sharply and wears away after a short period of use. There is a drawback in that the cage 2 cannot be fully supported and the cage 2 falls on the stove stand 1c of the inner cavity portion 3 and the charcoal 9 cannot be held at a constant height.

In the present invention, this point is improved, and the cage 2 is made of refractory metal, and as shown in FIG. 4, it is a flat disc shape having a cage eyelet with a gap in the longitudinal direction or the lateral direction, With the leg stands 2c, 2c, 2c attached to the periphery, the charcoal 9 can be placed on the stove stand 1c while maintaining a certain height and standing on its own. Further, the net 14 is placed on the stove 1, and the meat 15 is placed on it.

In the first ignition work, the nichrome wire of the electric heater 6a is energized and the generated hot air is blown onto the charcoal 9 for a short time (several seconds), so that the charcoal 9 is easily ignited. At this time, the blown air does not pass through the eye of the cage 2 and directly hits the charcoal 9 from the side, so that it is easy to ignite. After that, the power supply to the electric heater 6a is stopped, and the charcoal 9 is fueled by the air blow by the blower 7 to increase the heating power.

Further, in the above-described ignition device, if the blow-out nozzle 8a is provided with its axis (Y) direction deviated from the central direction (X) of the stove 1 as shown in FIG. The wind blows in a spiral shape in the inner cavity portion 3, and the charcoal 9 is efficiently burned.

Although the electric heater 6a has been described with reference to a nichrome wire which is easily available and has a low unit price, it goes without saying that another heat source can be used as long as it is a heat source using electricity.

In the figure, 12a, 12b and 12c are electric conductors, which connect the blower 7 and the electric heater 6a with the electronic control circuit device 11 and between the electronic control circuit device 11 and the power source. In addition, an exhaust pipe 16 for discharging smoke generated from the meat 15 to the outside is attached to the support frame 13, and the tip of the exhaust pipe 16 is connected to another exhaust pump device (not shown) and the inside of the support frame 13 is connected. Also, the smoke generated near the top and bottom of the table 10 is exhausted to the outside.

Further, the adjustment of the thermal power over time was almost impossible in the conventional example except for the adjustment of the charcoal, but in the present invention, the electronic heater 6a of the electric heater 6a is controlled by the separately provided electronic control circuit device 11. The power is turned on and off, and the intensity of hot air is adjusted by adjusting the temperature with a temperature sensor, the air volume is adjusted by adjusting the rotation speed of the blower 7, the wind is temporally adjusted, and stopped automatically. The timer automatically turns on and off with time, and the strength and weakness can be automatically and finely adjusted by the sensor, enabling compact installation without taking up the space for equipment.

Therefore, once the control pattern is programmed, it can be executed any number of times in the same pattern at any time. Therefore, the service operator first presses the start button of the electronic control circuit device 11, and The trouble of various adjustments related to the roaster is completely unnecessary until one group of customers finishes the meal, and can concentrate on the service of cooking ingredients. Further, if the control panel 12 incorporating such an electronic control circuit device 11 is attached to the edge portion of the table 10, anyone can easily operate it in a natural posture, which is more convenient. Absent.

As described above, since the present invention can perform ignition, temperature of hot air, strength of air blowing, air volume, time-on, off control, etc. all by using electricity, facility cost is low and space saving is possible. It has a unique advantage that it can be installed compactly, can be accurately controlled repeatedly, and that the smoke generated from the meat 15 can be exhausted to the outside of the table 10 by the exhaust pipe 16 and can be kept hygienic. is there. In addition, maintenance of equipment is rarely required for a long period of time, and repairs can be performed easily and at low cost.
