Detailed Implementation

[0046] The following is in conjunction with the appendix Figure 1-15 The present invention will be described in further detail below.

[0047] One embodiment of this utility model is shown below: Figures 1-4 , Figure 8 A fuel-fired collective food reheating device, comprising a cooking system, an oil supply system, a combustion system, and a control system;

[0048] See Figures 1-6 , Figure 8 and Figure 9 The cooking system adopts a split-type box structure, consisting of a heating box 1, a lid 10, a food shelf 3, and a box support 11. It is used to place food and achieve rapid heating of Class B collective foods, and has multiple functions such as steaming, stir-frying, and stewing. The heating box 1 includes an outer box 4 and an inner box 12. The inner box 12 is the cavity for heating food. It is made of stainless steel to meet food safety requirements, and its outer side is coated with an infrared absorption coating, which can fully absorb infrared radiation and heat in the flue gas and improve heat exchange efficiency. The box support 11 has a detachable structure. When in use, it is first placed on the upper surface of the burner, and then the heating box 1 is placed on it. It is used to support the heating box 1 and also leaves an air inlet and outlet channel between the burner and the heating box 1, which plays a role in combustion.

[0049] The outer casing 4 is coated with a semi-gloss military green coating to improve concealment and anti-surveillance capabilities. The outer casing 4 is made of aluminum alloy and is composed of two parts: a first side plate 401 and a second side plate 402 with multi-folded edges. The bottom of the outer casing 4 is open to facilitate direct heating of the inner casing 12. The top of the first side plate 401 is sealed to the top of the inner casing 12 through a first sealing plate 4011, and the top of the second side plate 402 is sealed to the top of the inner casing 12 through a second sealing plate 4021, thus achieving connection and sealing between the outer casing 4 and the inner casing 12 at the top.

[0050] A left upper smoke baffle 403 is provided on one side of the top of the outer casing 12, and a right lower smoke baffle 404 is provided on the other side of the bottom of the outer casing 12. A smoke exhaust window is provided on the left side wall of the left upper smoke baffle 403. Small smoke exhaust holes that cooperate with the smoke exhaust window are evenly provided on the upper side of the left side wall of the first side plate 401. Through the cooperation of the left upper smoke baffle 403 and the right lower smoke baffle 404, a three-pass flue is formed in the gap between the inner casing 12 and the outer casing 4, so that the heat in the flue gas can fully contact the inner casing 12 and be absorbed, reducing heat loss. Finally, the flue gas is discharged to the outside from the smoke exhaust window through the small smoke exhaust holes.

[0051] The top of the lid 10 and both sides of the outer box 4 are provided with adhesive handles 13. The lid 10 is provided with adhesive handles 13, which are convenient to use and will not cause burns due to high temperature. Each side of the outer box 4 is provided with an adhesive handle 13 for easy handling of the heating box 1. One side of the lid 10 is connected to the first side plate 401 of the outer box 4 by a hinge, and the other side of the lid 10 is connected to the second side plate 402 of the outer box 4 by a buckle 14, which facilitates the closing and locking of the inner box 12 as well as its opening.

[0052] See Figure 6 , Figure 10 The food shelf 3 consists of a food partition 302 and a bottom support plate 301, which are connected by a cylindrical hinge. The food partition 302 has evenly spaced slots, and the bottom support plate 301 has an adjustable bolt 303 that is movably inserted into it. The adjustable bolt 303 is threaded with an adjusting nut. By adjusting the adjustable bolt 303 and the adjusting nut, it is easy to support and fix the tilted food partition 302 after rotation. The bottom support plate 301 has a porous structure. The food shelf 3 keeps the bagged food upright in the box, which is conducive to the vertical flow of steam in the box to fully heat the food and ensure the efficiency and time requirements of food heating. The food shelf 3 adopts a folding structure for easy storage when not in use.

[0053] See Figure 7 , Figure 8 The combustion system consists of a frame assembly 2, an air pump 7, an atomizing assembly, an ignition assembly 9, and a combustion cylinder assembly 5. Its main function is to achieve combustion of atomized fuel through ignition to heat the food inside the heating chamber 1. The air pump 7, the atomizing assembly, the ignition assembly 9, the combustion cylinder assembly 5, as well as the fuel supply system and the control system are all integrated into the frame assembly 2.

[0054] See Figure 2 , Figure 3 , Figure 4 , Figure 8 The frame component 2 includes a frame 201, which is made of rectangular aluminum alloy tubing and uses lightweight materials such as aluminum plates and titanium plates to improve its portability in the field. The bottom of the frame 201 is provided with a base plate 202. The frame 201 is covered by four thin plates: an operation panel 203, a left side plate 204, a rear side plate 205, and a right side plate 206. The fan 17 is installed on the inner wall of the rear side plate 205. The rear side plate 205 has mounting holes that cooperate with the fan 17, which facilitates the installation and fixation of the fan 17 on the rear side plate 205. The bottom end of the operation panel 203 is rotatably connected to the frame 201. The operation panel 203 is provided with a lock 15 to facilitate the rotation, opening, closing, and locking of the operation panel 203.

[0055] See Figure 7 , Figure 8 , Figure 11 , Figure 12 , Figure 13 The combustion chamber assembly 5 (burner) includes a cylindrical combustion chamber 501 and a radiation trap 502. The cylindrical combustion chamber 501 is installed in the radiation trap 502, which is installed on the top of the frame 201. The bottom of the radiation trap 502 is provided with a wrapping layer 503. The semi-enclosed combustion chamber, combined with the flue structure formed by the upper left smoke baffle 403 and the lower right smoke baffle 404, improves the equipment's operating capacity and heating efficiency.

[0056] The cylindrical combustion chamber 501 has a porous mesh structure and adopts a two-stage expansion and decompression design inside, which reduces the velocity of the atomized oil flow entering the cylindrical combustion chamber 501, absorbs more heat in a shorter stroke, and rapidly vaporizes and burns (enhanced combustion). This allows the cylindrical combustion chamber 501 to form a high-temperature radiator in a short time and transfer heat outward. The central area of ​​the radiation trap 502 adopts an inverted cone-shaped geometric structure with high reflectivity. Its circumferential radiant heat plays a role in concentrating and reflecting heat through reflection and other mechanisms. It can reflect the heat transmitted from the four directions of the cylindrical combustion chamber 501 upward and combine with the cylindrical combustion chamber 501 to form a directional radiative heat transfer heat source, which transmits heat upward and improves the utilization efficiency of the burner's combustion and heating.

[0057] One end of the cylindrical combustion chamber 501 is connected to a mounting plate 5011, which is installed on the outer side of the wrapping layer 503. The oil-air mixing valve 8 is installed on the side of the mounting plate 5011 away from the cylindrical combustion chamber 501.

[0058] See Figure 7 , Figure 8 The air pump 7 mainly provides compressed air and is the only power source for fuel injection, atomization and combustion air entrainment. The selected air pump can provide sufficient compressed air to ensure complete combustion.

[0059] See Figure 11 , Figure 12 , Figure 13 The atomizing component uses a combined nozzle, which can shear and impact droplets through high-speed rotating airflow, ensuring thorough mixing of oil and gas before being ejected at high speed from the nozzle to form an atomized oil-gas torch. This nozzle has the advantages of a large atomization cone angle, low power consumption, and good atomization effect.

[0060] See Figure 12 , Figure 13 The ignition assembly 9 adopts low-pressure energy storage ignition. The ignition assembly 9 consists of a low-pressure energy storage ignition rod 901, a wiring harness, etc. The low-pressure energy storage ignition rod 901 is installed on one side of the oil-gas mixing valve 8 through the mounting bracket 902. The atomized oil and gas are ignited by the high temperature generated by the low-pressure energy storage ignition rod 901.

[0061] See Figure 13 , Figure 14 The fuel supply system consists of a fuel tank 6, a fuel supply pipeline, a fuel-air mixing valve 8, and a fuel level sensor, providing fuel for combustion. The fuel tank 6 has an irregular shape to make full use of space. A filler port 602 is provided on one side of the top of the fuel tank 6, and a fuel level sensor valve seat 601 is provided on the other side of the top of the fuel tank 6. The fuel level sensor is installed inside the fuel tank 6 through the fuel level sensor valve seat 601. A fuel supply interface is provided on one side of the fuel tank 6, and a fuel tank outlet connector 603 is connected to the fuel supply interface. One end of the fuel supply pipeline is connected to the fuel tank outlet connector 603, and the other end is connected to the fuel inlet connector of the fuel-air mixing valve 8. A fuel circuit solenoid valve is connected in series on the fuel supply pipeline. When the fuel circuit solenoid valve is opened, under the action of low-pressure air, the fuel is injected from the fuel tank 6 through the fuel supply pipeline into the fuel circuit channel of the fuel-air mixing valve 8, and then enters the atomizing component for atomization, providing conditions for ignition and combustion.

[0062] See Figure 3 , Figure 4 , Figure 7 The control system consists of a control circuit board 18, operation buttons 16, a fan 17, a power connector 2041, wiring harnesses, etc. It provides power to the equipment and controls its operation.

[0063] A converter is required to power the burner using AC220V. The control circuit board 18 is the core component, integrating a CPU chip and various functional modules (igniter on / off control, oil circuit solenoid valve energization control, low oil level alarm and timing display, etc.) and components. The operation button 16, fan 17, and power connector 2041 are all mounted on the frame assembly 2. The operation button 16 controls the start and stop of the equipment; the fan 17 cools the electrical components and piping, preventing damage from high temperatures that could cause malfunctions; the power connector 2041 is the equipment's power supply interface. All functional components are connected via wiring harnesses to ensure the normal operation of the equipment. The equipment's operating logic is as follows: Figure 15 As shown.

[0064] Working principle:

[0065] The heating chamber 1 is placed on top of the combustion cylinder assembly 5 via the chamber support 11. Fuel is supplied to the combustion chamber through the fuel supply system. Through the cooperation of the combustion system and the control system, the atomized fuel is ignited to achieve combustion, thereby heating the food inside the heating chamber. This fuel-based heating of food facilitates stable and sufficient heating of Category B food, allowing the food to cook quickly and thus improve its edibility and taste.

[0066] The installation positions of the control circuit board 18, operation button 16, and power connector 2041 can be selected on the four thin plates according to actual usage needs. In the above embodiment, the operation button 16 and control circuit board 18 are installed on the thin plate of operation panel 203, and the power connector 2041 is installed on the thin plate of left side panel 204.

[0067] The control circuit board 18, power connector 2041, fan 17, air pump 7 and other components in the above embodiments are all existing technologies, which are mature technologies mastered by those skilled in the art and can be purchased from the market. In this embodiment, they are only used and their structure and function are not changed.

[0068] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
