Abstract

------02/09/2563------(OCR) Charcoal stove for cooking, made of metal. Consists of: stove structure, stove cover, central support plate, charcoal loading port, air inlet, air inlet shield, secondary air vent, honeycomb core, combustion chamber, thermal insulation, and ash tray. It has three cylindrical metal tubes of different sizes; the central tube is the combustion chamber. The space between the tubes has inner compartments for secondary air vents, and the outer compartment contains thermal insulation. An air void acts as thermal insulation before the side covers. Two air inlet vents are drilled, one at the front and one at the back, in a conical shape to allow air to flow in and hit the air shield under the honeycomb. There is also a charcoal loading port with a charcoal pushing tube and a cover to prevent heat transfer through this port. ------------ Page 1 of 1. Summary of Invention: Charcoal stove for cooking, made of metal, consisting of: stove structure, stove cover, central support plate, charcoal loading port, air inlet, air inlet shield, secondary air vent, honeycomb core, combustion chamber, thermal insulation, and ash tray. There are three cylindrical metal tubes of different sizes, with the combustion chamber in the center. The spaces between the tubes are secondary air vents, while the outer spaces contain thermal insulation. An air cavity acts as a preliminary insulation layer. The side cover has two air inlet vents, one at the front and one at the back, conical in shape, allowing air to flow in and hit the air baffle under the honeycomb. There is also a charcoal loading port with a charcoal pushing tube and a cover to prevent heat from escaping through this port.

Claims (3)

------02/09/2563------(OCR) 1. The charcoal stove for cooking, according to this invention, consists of a stove body structure (11), a middle support plate (6). Inside the stove, it is divided into three parts. The first part is the top of the honeycomb plate (8), which contains the combustion chamber (5) and the stove base plate (10). The second part is the bottom of the honeycomb plate, which contains the stove front opening or air inlet (4), the air inlet shield (15), and the ash tray (3). The third part is the sides of the combustion chamber, which contains the secondary air inlet (2), thermal insulation (7), an air cavity (16), the stove surface cover (1)(9)(12), and the charcoal compartment (14). It has a special feature: the stove front opening or air inlet (4) has two conical openings on opposite sides, which allow air to flow through these two stove front openings and hit the air inlet shield (15), causing air from both sides to hit the shield and then flow into the center of the honeycomb plate, spreading up into the combustion chamber. Some air also flows into the secondary air inlet (2). 2. Charcoal stove for cooking, according to claim 1, on the side of the combustion chamber (5) there are 3 layers of openings. The inner layer is a secondary air channel (2) to allow additional air to enter the upper part of the combustion chamber through the air holes (13). The middle layer is a thermal insulator and the outermost layer is an air cavity that acts as another layer of thermal insulation. 3. Charcoal stove for cooking, according to claim 1, with a charcoal filling opening on the side with a charcoal pushing tube and a lid (14) ------------ Page 1 of 1 page of claims As shown in Figure 1, a disassembled perspective view of the charcoal stove for cooking according to this invention, which consists of a charcoal stove for cooking consisting of a stove cover (1X9X12), a secondary air vent (2), an ash tray (3), an air intake vent (4), a combustion chamber (5), a central support plate (6), a thermal insulation (7), a honeycomb (8), a stove support plate (10), a stove structure (11), a charcoal filling opening (14), and an air intake shield (15). The stove structure (11) is a rectangular metal frame, separated into 2 layers, to support the various components of the charcoal stove for cooking. There are three cylindrical metal pipes of different sizes fitted down from the top. The first pipe, the smallest, is on the inside and serves as the combustion chamber (5). The top of this cylinder has holes for air to flow into the upper part of the combustion chamber (13). The second pipe, medium in size, is the middle pipe and is longer than the inner pipe. The space between the inner and middle pipes is a secondary air vent (2). The third pipe, the largest, is the same length as the first pipe and is fitted on top as a ring. The space between the middle and outer pipes is for insulation (7). All three pipes are suspended from the top lid of the kiln (9) and the middle support plate (6). At the very top of the kiln is a kiln stand (10) covering it. Inside the kiln, below the combustion chamber, is a honeycomb plate (8). At the bottom, there is an ash tray (3) and a kiln floor (1) covering the bottom. The sides of the charcoal kiln are covered with side covers (12) on all four sides, two of which have holes for fastening the vents. The air enters through a conical inlet (4) and one side has holes for attaching pipes to form a charcoal filling port (14). A special feature is that under the honeycomb, there is an air baffle (15) suspended below the honeycomb so that the air flowing in through the two conical air inlet ports (4) flows through the baffle and then flows up to the center, spreading through the honeycomb into the combustion chamber. There is a charcoal filling port with a charcoal pusher pipe and a cover to prevent heat from escaping through this filling port, as shown in Figures 3 and 4. Inside the kiln, there are three cylindrical tubes of different sizes with two gaps between them. The inner gap is for secondary air (2), and the second gap is for thermal insulation (7). There is also another gap between the outermost cylindrical tube and the side wall of the charcoal kiln, which is an air cavity (16) to allow the air to act as thermal insulation, as shown in Figures 2 and 3.
