[0001] The present invention relates to a charcoal grill having a heat generating, heat retaining and heat storage unit, and more particularly to a method for igniting and burning charcoal or the like in the charcoal grill. This invention relates to a charcoal grilling device that uses a cooking iron plate as a second heat source, such as an electric heating iron plate cooking device that uses electricity as a heat source, such as a hot plate or an electric barbecue grill, or a gas heating cooking device for barbecue cooking that uses city gas or LP gas as a heat source. In other words, this invention relates to a dual heat source charcoal grilling device that operates in combination with a heating device that uses another heat source, such as electricity or LP gas. Background of the technology

[0002] There are barbecue cooking devices that directly heat and burn solid fuels such as charcoal using a heating device that uses electricity, LP gas, etc. as a heat source. In recent years, due to the shortage of oil and liquefied gas, measures are needed to deal with the soaring prices of gasoline, liquefied gas, electricity, and gas. Energy conservation is being demanded. [Prior art documents] [Patent documents] [Patent Document 1] Patent publication: Patent application No. 2020-85435 "Charcoal fire tabletop cooker" Summary of the Invention

[0003] When solid fuels such as charcoal are burned, incomplete combustion can occur, producing CO and CO2, which can lead to carbon monoxide poisoning. [Problem to be solved by the invention]

[0004] The inventor of the present application has in his patent document 1, Japanese Patent Application No. 2020-85435, entitled "Charcoal Fire Tabletop Cooker," which discloses that a heat-retaining and ventilation layer is formed below the combustion area of ​​a charcoal heater for burning ignition material and solid fuel such as charcoal, and that the heat-retaining effect of the ignition and combustion part makes it easier to ignite and burn the ignition material. Furthermore, it discloses that an electric iron plate cooker is installed below the bottom surface of the charcoal heater, and the heating by the electric iron plate cooker below is used to assist the combustion in the combustion area, making it easier to ignite and burn the ignition material.

[0005] Therefore, the invention of Patent Document 1 adds heating from an electric iron plate cooker to make it a two-heat source iron plate cooker, and by operating a charcoal grill heating device in combination with a heating device that uses other heat sources such as electricity or LP gas, there is the problem of having to deal with temporary power outages and requests to save electricity due to supply shortages of commercial electricity, etc.

[0006] Therefore, in order to reduce the amount of electricity and gas used by the second heat source in a dual heat source charcoal grilling and heating device that is operated in conjunction with a heating device that uses another heat source such as electricity or city gas, The object of the present invention is to automatically control and stop the combustion state of the second heat source device in response to changes in the operating state and combustion state of the charcoal grilling device. [Means for solving the problem]

[0007] The first invention of the present application provides a heat-generating and heat-retaining heat storage unit comprising: a heat storage case 10 having a substantially sealed box shape whose entire surface is made up of heat-shielding, heat-resistant wall surfaces; a heat storage block 1 including a heat-generating and heat-retaining assembly B2 inserted inside the heat storage case 10; and a heat-generating and heat-retaining case 20 having a box shape with an open top, whose bottom surface 21 and peripheral surface 22 are made up of heat-shielding, heat-resistant wall surfaces; and a heat-generating and heat-retaining block 2 including the heat-generating and heat-retaining assembly B2 inserted into the sealed space inside the heat-generating and heat-retaining case 20. The second invention of the present application is to form a charcoal ignition and combustion area above a heat generating, heat retaining, and thermal storage unit having a heat storage block 1 including a heat generating and heat retaining assembly B2 and a heat generating and heat retaining block 2 including the heat storage assembly B2, and store heat in the heat storage assembly B2 of the heat generating, heat retaining, and thermal storage unit below solid fuel such as charcoal in the charcoal ignition and combustion area, Prior to igniting and burning solid fuel such as charcoal in the charcoal ignition and burning area, the heat generating and heat retaining assembly B2 of the heat generating and heat retaining heat storage unit is heated to heat the area below the charcoal ignition and burning area. The third invention of the present application is a dual heat source charcoal grill that uses a solid fuel such as charcoal as a heat source and a heating device that uses other heat sources such as electricity and LP gas. Under the fire starting unit of the charcoal grill heating device, The heat storage case is equipped with a heat-shielding heat-resistant wall on all sides, a sealed space within the heat storage case, and a heat storage block including a heat storage assembly. A vertical hot air space is formed adjacent to the heat storage block, The heating and cooking surface of a heating device serving as another heat source is provided in contact with the bottom surface of the heat storage block and located at the bottom surface of the vertical hot air space, Prior to the ignition and combustion of solid fuel such as charcoal in the charcoal ignition and combustion area, the heat generating and heat retaining assembly B2 of the heat generating and heat retaining heat storage unit is heated, The heat generated by the heating device, which is a heat source of another type, is stored by thermal conduction with the bottom surface of the heat storage block, and hot air is also supplied to the vertical hot air space by the generated heat. It is characterized by heating the charcoal ignition combustion area to a high temperature. The fourth invention of the present application is a dual heat source charcoal grill that uses a solid fuel such as charcoal as a heat source and a heating device that uses other heat sources such as electricity and LP gas. A heat generating, heat retaining, and heat storage unit is installed below the charcoal ignition and combustion area of ​​the charcoal grill. A vertical hot air space is formed adjacent to the heat generating, heat retaining and heat storage unit. The heating and cooking surface of a heating device serving as another heat source is provided in contact with the bottom surface of the heat generating and heat retaining heat storage unit and is located at the bottom surface of the vertical hot air space. After the charcoal ignition and combustion area of ​​the charcoal grilling device is ignited, combustion air is supplied to the combustion area to switch to full charcoal combustion operation, By equipping the top cover, the unit will switch to warm-keeping standby mode. In the warming standby operation state, the hot air in the vertical hot air space is prevented from rising by the top cover and falls toward the cooking surface of the heating device, which is another heat source, thereby heating the cooking surface. When the temperature of the cooking surface rises above the sensor set value, operation is automatically stopped. Effect of the Invention

[0008] This invention stores heat in the heat storage block and vertical hot air space and heats the fire starting unit, thereby making it possible to maintain a high temperature in the ignition and combustion area when igniting and burning solid fuels such as charcoal. This has the effect of eliminating incomplete combustion when burning solid fuels such as charcoal, preventing the generation of CO and CO2, and preventing carbon monoxide poisoning accidents. In addition, when the combustion area is set to keep warm, the cooking griddle of a heating device that uses another heat source is heated, and the cooking griddle is heated to a temperature higher than the set value, and the operation of the cooking griddle is stopped, which has the effect of saving on the use of other heat sources such as electricity, city gas, and LP gas.

[Figure 23] An explanatory diagram of the housing of the charcoal grill heater having a flat plate assembly structure. Preferred embodiments of the invention

[0010] In the first invention of the present application, "Hichirin" is applied as a charcoal grilling heating device P1 that uses solid fuel as a heat source. As the heating device P2 of the second heat source such as electricity or LP gas, a hot plate having an electric heating surface, for example an IH heater, is applied. A heat generating, heat retaining and heat storage unit A is installed below a combustion area Q for solid fuel such as charcoal. The heat generating, heat retaining, and heat storage unit A includes a heat generating, heat retaining block 2 having an insulation case 20 whose entire periphery is a shielding wall surface and has a delayed opening formed in one part, and a heat storage block 1 having a heat storage case 10 whose entire surface is a shielding, heat-resistant wall surface. A box-shaped heat storage case 10 made of cast iron or ceramic is used as the heat storage block 1, and the sealed space inside the heat storage case is filled with heat storage assemblies 11. The heat capacity of the heat storage block 1 can be freely set by selecting the material of the heat storage assemblies 11, the amount of filling, and the shape and volume of the sealed space. The second invention of the present application is a charcoal ignition and combustion method using the heat generating, heat retaining, and heat storage unit A as described below. A heat retention case 20 of a heat generating and heat retaining block 2 is placed above a heat storage block 1 including a heat storage assembly 1 . After equipping the heat-generating and heat-retaining assembly B2 inside the heat-retaining case 20, A charcoal ignition and combustion area is formed above the heat generating and heat retaining thermal storage unit including the heat generating and heat retaining block 2. The heat storage assembly B2 of the heat generating, heat retaining and heat storage unit stores heat under solid fuel such as charcoal in the charcoal ignition and combustion area. Prior to igniting solid fuel such as charcoal in the charcoal ignition combustion area, the heat generating and heat retaining assembly B2 of the heat generating and heat retaining heat storage unit is made to generate heat. Thus, the charcoal ignition combustion area is characterized in that the area below the solid fuel such as charcoal is heated. In the third invention, in addition to the first invention, a "Hichirin" is selected as the charcoal grill P1, and an outside air intake K1 is provided at the lower end of the side wall of the main housing A of the "Hichirin". The center of the bottom wall of the main housing is cut away to form a bottom opening 3 . The bottom surface 13 of the heat storage case of the heat storage block 1 is configured to penetrate the bottom opening and be in surface contact with the hot plate, e.g., the electric heating surface 4 of an IH heater, and to conduct heat from the hot plate, e.g., the electric heating surface 4 of an IH heater, to the heat storage block 10. In the fourth aspect of the present invention, a top cover 5 is additionally provided to the charcoal grill P1. In the warming standby operation state, the hot air in the vertical hot air space H2 is prevented from rising by the top cover 5 and falls, heating and storing heat on the electric heating surface 4 of a hot plate, for example an IH heater. As a result, the electric heating surface 4 of a hot plate, for example an IH heater, becomes hotter and exceeds the sensor setpoint, causing the second heat source heating device P2 to automatically shut down. EXAMPLES

[0011] The heat generating, heat retaining and heat storage unit A will be described with reference to Figs. The heat generating and heat retaining thermal storage unit A is composed of a sealed thermal storage block 1 and a heat generating and heat retaining block 2. The sealed heat storage block 1 uses a box-shaped sealed heat storage case 10 made of cast iron or ceramic, and the sealed space inside the heat storage case is filled with heat storage assemblies B1. The heat capacity of the sealed heat storage case 10 can be freely set by selecting the material of the heat storage aggregate B1, the filling amount, the shape and volume of the sealed space, and the like.

[0012] The sealed heat storage case 10 has a structure in which the entire surface is a heat-shielding, heat-resistant wall surface, and may be a press-molded steel plate having an internal sealed space H1, and is configured as a sealed case. When air or nitrogen is sealed in the sealed space H1 and the gas is used as a heat storage material, an air vent safety valve is required because the internal air pressure rises when heated, but the safety valve can be omitted and a through hole formed in the side or top surface instead of the safety valve, so that the container is not limited to a completely sealed container. In other words, it also includes a container in which multiple through holes are formed in part of the side surface.

[0013] The heat storage aggregate B1 corresponds to the above-mentioned air and nitrogen B10, as well as simple substances such as liquid B11 and solid B12. Liquid B11 includes water and other liquids that have heat retention and heat storage functions, but does not include flammable liquids such as gasoline and alcohol or liquids that generate dangerous gases. As the solids and solid materials B12, ceramic heat-insulating and heat-storing materials B12a such as granular stones, granular cut stone chips, ceramic chips, and volcanic ash molded products; Metal-based heat-retaining and heat-storing materials B12b, such as iron powder, granular iron powder moldings, metal cuttings, granular cuttings moldings, metal plate pieces, and ball-shaped metal moldings; Furthermore, mixed metal-based heat-insulating materials M12c such as iron powder, granular iron powder moldings, metal cuttings, granular cuttings moldings, metal plate pieces, and ball-shaped metal moldings may be mixed. Furthermore, only the ceramic heat-insulating material M12a and the metal heat-insulating material M12b may be mixed. Also, the heat storage aggregate B3 obtained by mixing and blending these is included.

[0014] For the heat generating and heat retaining block 2, a box-shaped heat generating and heat retaining case 20 is used, and the sealed space inside the heat generating and heat retaining case 20 is filled with the heat generating and heat retaining aggregate B2. The heat generating and heat retaining case 20 is a metal molded product having a bottom surface 21 and a peripheral surface 22 which are continuously formed and an open top surface, and the bottom surface 21 and the peripheral surface 22 form a heat-shielding, heat-resistant wall surface. The heat generating and heat retaining case 20 is not limited to metal products, but is a widely applicable shielding and heat resistant structure. For example, it can be a ceramic product or a cement product. Furthermore, it can be a shielding and heat resistant structure by securing shielding properties as a molded paper product such as cardboard, and securing heat resistance by coating with heat resistant paint. The lower half of the peripheral surface 22 of the heat generating and insulating case 20 is a shielded and heat resistant structure, but the lower half can also be an open or semi-shielded and heat resistant structure. For example, a delayed opening structure 22a can be considered, in which Japanese paper is pasted to provide a shielding function but no heat resistance, and the structure is burned away during internal combustion.

[0015] Heat generating and heat retaining aggregate M2 is made of paper, vegetable fiber, rice husk, cutting branches, wood chips, vegetable fiber, rice husk, bamboo, wood chips, carbonized processed products made by steaming vegetable fuel "smoke generating heat generating material", charcoal, bamboo charcoal powder, granules, cutting pieces - carbide heating element M2a mixed with ceramic heat retaining material M2b such as granular stone, granular cutting stone chips, ceramic cutting chips, volcanic ash molded products, etc., to enhance heat storage as an aggregate, and may also be mixed with metal heat retaining material M2c such as iron powder, granular iron powder molded products, metal cutting chips, granular cutting chip molded products, metal plate pieces, ball-shaped metal molded products, etc.

[0016] The heating and heat storage plate 3 will now be described. In plan view, it has a flat plate shape similar to the heating and heat storage unit A, and is made of cast iron, ceramic, and diatomaceous earth, a molded product made of materials with high heat retention. Referring to Figure 11, Figure a is a ceramic slab made of natural stone and has no through holes. Figure b shows a diatomaceous earth molded product, a natural stone ceramic plate, a grate plate 30 having long holes and lattice-shaped through openings 31. Figure c shows a ceramic molded product with numerous through holes.

[0017] Heat storage in the heat generating / insulating heat storage unit A: The carbide heating element M2a of the heat generating and heat retaining block 2 is heated from above and generates heat when combustion begins due to ignition in the ignition combustion area Q above it. The heat generated by the heat generating and heat retaining block 2 heats the heat storage block 1 located below it. As a result, the heat storage block 1 of the heat generating, heat retaining and heat storage unit A stores heat.

[0018] It should be noted that by placing the heating and heat storage plate 3, which has been heated by other heating means and put into a heated state, on the upper surface of the heat generating, heat retaining and heat storage unit A, it is possible to similarly store heat in the heat storage block 1. Moreover, by bringing a heated heat storage plate 3 into contact with the top or bottom surface of the heat storage block 1, heat can be similarly stored in the heat storage block 1. For example, by placing a hot food item being cooked on a city gas stove, an iron pot for cooking and a barbecue plate for cooking = a heat storage plate 4a, on the top surface of the heat generating and heat retaining block 2 of the heat generating and heat retaining heat storage unit A, the heat storage block 1 is heated and heat is stored. As a result, the hot food item F being cooked on the iron pot for cooking and the barbecue plate for cooking 4a is kept at a high temperature and kept warm, or is continuously heated and cooked.

[0019] The charcoal heater housing 9 of the charcoal grill P1 will be described with reference to Figs. The charcoal heater P1 is a cylindrical or rectangular box-shaped molded product, generally a diatomaceous earth molded product, but there are a wide variety of ceramic and metal products that have heat insulation and heat resistance. Referring to FIG. 12A, the charcoal heater P1-1 is a cylindrical Hichirin "Shichirin" having an opening K1 formed at the lower end of the side wall. Referring to FIG. 12B, the charcoal heater P1-2 is a box-shaped Hichirin "Shichirin" that is rectangular in plan view, with an opening K1 at the lower end of the side wall and an opening K2 at the lower end of the side wall. Referring to FIG. 12(c), the box-shaped "yakiniku stove" that is rectangular in plan view has an opening formed in the bottom surface, or the bottom surface is meshed to form a bottom opening K3. Referring to Figure 13(a), the charcoal heater P1-5 is a charcoal stove for local heating, with the ceiling fully open and the other sides, including the bottom, completely sealed. It is a heat-retaining charcoal heater. Referring to FIG. 13B, the charcoal heater P1-4 has an open ceiling and the other sides, including the bottom, are almost completely sealed, but there are also some that have an opening at the bottom - for example, a charcoal briquette brazier.

[0020] Referring to FIG. 14, the heat generating, heat retaining and heat storing unit A is installed inside the charcoal heater P1-3 and the charcoal heater P1-4. 14A, a hot air space HH is formed between the peripheral wall of the charcoal heater P1 and the surrounding surface of the heat generating, heat retaining and heat storing unit A. As shown in FIG. Referring to FIG. 14C, a vertical hot air space HH-2 is formed which penetrates the center of the heat generating and heat retaining thermal storage unit A.

[0021] The top cover 5 will be described with reference to FIG. The top cover 5 has a shape suitable for covering the upper part of the top surface of the charcoal heater housing 9. Like the charcoal heater housing 9, it is generally a molded product of diatomaceous earth, but it is also a molded product of a material having heat insulating and heat resistant properties, such as ceramics or metal products. The top cover 5 is formed with a plurality of openings K5 and a delay opening K5a. In the warming standby operation state, the hot air ff in the vertical hot air space is prevented from rising by the top cover 5 and falls, heating and storing heat on the electric heating surface 4 of a hot plate, for example an IH heater.

[0022] 16, when integrating a charcoal grill P1 using solid fuel such as charcoal as a heat source with a hot plate, for example an IH heater P2, a flat support bracket 7 having protrusions 6 that come into contact with the peripheral portion of the bottom wall of a main body housing 9 is interposed. Thermal conduction between the peripheral portion of the bottom wall of the main body housing 9 and the second heat source heating device P2 (electric heating surface 4 of a toaster oven) is reduced or stopped, thereby saving power to the second heat source heating device P2.

[0023] The inner case 8 will be described with reference to FIG. A cylindrical heat-resistant metal inner case 8 is provided inside the side wall of the main housing 9, and an outside air supply space Hh is formed outside the vertical hot air space HH, and a combustion air supply path 80 is formed from the outside air supply space opening to the combustion area Q of the charcoal grilling heating device.

[0024] Combustion in the combustion area Q will be described with reference to FIG. The combustion area Q is a mixture of an ignition section, an ignition section, and a combustion section, and the ignition section is connected to the vertical hot air space HH. The ignition section is adjacent to the ignition section. 18b, the vertical hot air space HH and the ignition part are located in the center. Therefore, when ignition and combustion occurs, combustion air is supplied vertically to the center. It burns horizontally from the ignition point to the adjacent ignition point. Referring to Fig. 18c, the vertical hot air space HH and the ignition part are located on the periphery. Therefore, when igniting and burning, the combustion air is supplied from the vertical hot air space H1 and the ignition part horizontally toward the center, and burns horizontally from the ignition part to the adjacent ignition part. When the charcoal in the Combustion Area Q is ignited and burned, a flame is generated upward, and the stove enters the operating state as a charcoal stove - the charcoal burning state.

[0025] Referring to FIG. 19, in the warming standby operation state, the hot air ff in the vertical hot air space is prevented from rising by the top cover 5 and falls, heating the electric heating surface 4 of the heating device P2 (toaster oven) of the second heat source. When the electric heating surface 4 of the heating device P2 (toaster oven) serving as the second heat source becomes hotter than the set temperature, the heating device P2 serving as the second heat source stops operating.

[0026] In the above embodiments, the heat generating and heat retaining case 20 and the heat storage case 10 are in various shapes such as square, polygonal, circular, elliptical, etc. in cross section and plan view, and are box-shaped with flat peripheral surfaces, but the peripheral surfaces may be curved or have a compound flat shape. A: Drum-shaped, B: Sake barrel-shaped, C: Inverted cone-shaped, D: Combined normal and inverted cone-shaped, and other combined types are possible. By reducing the bottom surface, the thermal conduction during heat storage is reduced, and in a structure where the bottom surface is separated from the heater heating surface, heating is only by hot air.

[0027] 21, the heat storage case 10 is a composite molded product made of a plurality of heat-resistant and heat-retaining materials. 10-1 is steel, 10-2 is pumice, and 10-3 is cement.

[0028] 22, the housing 9 is a composite molded product made of a plurality of heat-resistant and heat-insulating materials. 10-1 is steel, 10-2 is pumice, and 10-3 is cement. 23, the housing 9 is made of a cylindrical heat-resistant, heat-retaining synthetic molded product having a structure of a plurality of flat plates 90. The housing 9 is assembled to form a rectangular or polygonal cylindrical structure. [Industrial Applicability]

[0029] The present invention provides a heat generation and insulation means for charcoal heaters that use solid fuels such as charcoal, which can replace the conventional insulation means made of ash such as straw incineration ash. By providing a heat storage means, the ignition and combustion of carbonized solid fuels such as charcoal can be easily and reliably achieved, and accidents involving the generation of monoxide due to incomplete combustion can be prevented, thereby promoting the consumption of carbonized solid fuels such as charcoal and contributing to industrial development.
