Description

Technical Field

[0001] This invention relates to the field of cooking equipment technology, specifically to an integrated, modular fast food heating device. Background Technology

[0002] When conducting exploration, patrol, and rescue missions in the field for more than half a day, food support is essential, especially when missions are carried out in the field for several consecutive days. Fresh vegetables and meat require refrigeration and freezing, but in the field, it is difficult to provide reliable electricity to power refrigeration and freezing equipment. Furthermore, even with electricity, the daily consumption of hundreds of kilograms of fresh food by dozens or even hundreds of people necessitates large cold storage facilities. However, in the field, where there are no fixed locations and frequent relocations, building cold storage is impractical. In recent years, pre-prepared foods that can be stored at room temperature have emerged, primarily in soft-pack canned form. These foods separate staple foods and side dishes, do not require refrigeration or freezing, and can be stored at room temperature for extended periods. After heating, they provide a nutritious and energy-rich meal with good taste, making them particularly suitable for large-scale food support for dozens or hundreds of people. Therefore, for those conducting missions in the field, carrying pre-prepared foods and heating equipment is sufficient to meet their daily food needs.

[0003] Currently, there are relatively few devices suitable for large-scale food heating in the wild. Common outdoor barbecue grills are unsuitable as they easily damage food, and small stoves used for outdoor cooking have limited processing capacity and cannot meet the food heating needs of dozens of people. Therefore, developing a highly integrated fast food heating device suitable for heating pre-prepared food under outdoor conditions is crucial for ensuring hot meals in the wild. In view of this, this invention is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated, modular fast food heating device to solve the technical problems existing in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: an integrated, modular fast food heating device, comprising: a heating chamber, a telescopic mechanism, a combustion system, and a base; wherein the heating chamber is connected to the base via the telescopic mechanism;

[0006] The top of the heating box body is provided with a box cover, the bottom of the box body is open, and a pot support device is provided on the bottom side wall edge of the box body. The pot body is hung on the bottom of the box body through the support device and moves up and down with the box body.

[0007] When the telescopic mechanism is extended, the pot body moves upward with the box body to a preset position, and the pot body is located on the support device, and the combustion system is activated to heat the pot body; when the telescopic mechanism is retracted, the pot body moves downward with the box body to fit the upper surface of the combustion system, and then the box body continues to move downward to fit the upper surface of the base.

[0008] In an optional embodiment, the inner side wall of the box body is provided with a plurality of food supports for holding food.

[0009] In an optional embodiment, the telescopic mechanism consists of four telescopic rods fixed to the base, with the four telescopic rods respectively connected to the four bottom corners of the box body.

[0010] In an optional embodiment, the lid opens or closes along the top of the box body, and a handle is provided on the lid.

[0011] In an optional embodiment, the combustion system includes a frame, a combustion cylinder is disposed within the frame, and a first enclosure and a second enclosure for heat flow guidance are respectively disposed on the top two sides of the frame.

[0012] In an optional embodiment, the combustion system further includes a fuel supply system, wherein the fuel tank of the fuel supply system is connected to the combustion system via a fuel pipe.

[0013] In an optional embodiment, the oil tank is equipped with an oil level sensor, an oil inlet, and an oil outlet, with the oil outlet connected to the oil pipe.

[0014] In an optional embodiment, the oil pipe is provided with a proportional regulating valve and an oil circuit solenoid valve, the proportional regulating valve being away from the oil tank and the oil circuit solenoid valve being close to the oil tank.

[0015] In an optional embodiment, the combustion system further includes an igniter, an atomizer, and an air pump.

[0016] In an optional embodiment, the food holder is foldable.

[0017] The beneficial effects of this invention are as follows:

[0018] (1) When not in use, the telescopic device is retracted, and food, pots, etc. are placed inside the heating chamber. The heating chamber covers the burner and contacts the upper surface of the base. The pot moves downward with the heating chamber and then stops moving downward, supported by the burner. When heating again, the pot continues to move upward under the action of the support device. The pot does not need to be repeatedly removed when cleaning is not required. When not in use, the entire device is in a closed state, small in size, easy to carry, and does not require an additional outer packaging box. The heating chamber itself is a box with packaging box function. When in use, the telescopic device is extended, which can quickly heat food and is convenient to use.

[0019] (2) The pot body of the device is placed in the support device (slot) at the bottom of the heating box. After the heating box is raised from the base to the preset position limit, the pot body is directly above the burner. Place the food in the food rack, then add water into the pot body, close the lid, and start the diesel burner to heat the pot body. After the water in the pot body is heated and evaporates, it forms water vapor. As the water vapor rises, it heats the food in the food rack, quickly heating the food. After heating is complete, open the lid and remove the food.

[0020] (3) The food support in this heating device is foldable and is used to place pre-prepared food, which can prevent food from coming into contact with each other and affecting the heating effect. In addition, a diesel burner is used as the heating source, and a small amount of water is added to the pot to quickly generate steam to heat the food, which results in fast heat generation and high heating efficiency.

[0031] Please see the appendix Figure 1-5 The purpose of this embodiment is to provide an integrated, modular fast food heating device, comprising a heating chamber 1, a combustion system 5, a pot body 3, and accessories. The heating chamber 1 consists of a cover 12, a body 11, a telescopic mechanism 4, a base 6, and the pot body 3. The body 1 consists of inner and outer chambers, a flue baffle, and an insulation layer. (See attached diagram.) Figure 3The combustion system 5 consists of a burner, an oil supply system 7, a power supply, and a control system. Spare parts include easily damaged and consumable components such as sealing rings and food racks 2. Following modular and integrated design requirements, the fast food heating device integrates the combustion system 5 and the heating chamber 1 into a single structure. When unfolding, select a relatively flat and solid surface, open the latches on the chamber body 11, and lift the chamber body to the preset position using the handle 13 and telescopic mechanism 4. Lock the chamber body 11, place the pot 3 into the bottom support device (slot) of the chamber body 11, add water to the pot 3, and place food in the food rack 2 to heat the food. The unfolding time does not exceed 10 minutes. When retracting, push the heating chamber 1 back to the base 6 along the telescopic mechanism 4. The heating chamber 1 adheres to the base 6, and the pot 3 adheres to the upper surface of the combustion system 5 and no longer moves downwards with the chamber 1. Through this integrated design, the heating chamber 1 serves as both a food heating box and an outer packaging box. It should be noted that the insulated steamer using the heating chamber 1 as the heating device and the outer packaging box eliminates the need for an additional packaging box, reducing the overall weight. The heat generated by the combustion system 5 directly heats the water inside the pot 3, producing steam to heat the food. The food support 2 is used to place and separate food, with gaps in between to allow steam to pass freely, increasing the heating area of ​​the food and improving heating efficiency. The main body 11 adopts an inner and outer chamber sandwich structure, including an outer chamber, a flue baffle, and an insulation layer, concentrating heat inside the chamber and preventing excessive heat loss to the outside, thus improving heat utilization. The lid 12 contains a sealing ring, and an exhaust valve is installed on the upper part of the lid 12. When the pressure inside the main body 11 reaches a certain value, the exhaust valve automatically opens, maintaining a slightly pressurized environment inside the chamber and improving heating efficiency.

[0032] The heating chamber 1 adopts an integrated structure. The upper part of the heating chamber 1 is the food heating chamber. The bottom of the main body 11 of the heating chamber 1 is open, with an opening at the bottom. Within this opening, a curved pot 3 can be placed through a support device (slot). A steaming tray with mesh holes can be designed, with the mesh holes evenly distributed on the surface of the steaming tray. The center of the steaming tray has four support feet, allowing it to be placed on the bottom of the pot, so that the edge of the steaming tray contacts the four walls of the pot 3. The distance between the upper edge of the steaming tray and the bottom of the pot is 10-30mm. Several round holes are evenly distributed on the surface of the steaming tray, allowing water to flow into the bottom of the pot through the round holes and allowing water vapor to rise from the round holes. When adding water to the pot 3, the water level should not exceed the upper surface of the steaming tray, maintaining the water volume at 1-2 liters, which can quickly boil and generate water vapor for food heating. A foldable food support 2 can be placed on the steaming tray for placing food. The pot 3 has handles at both ends, allowing it to be removed from the heating chamber 1 when cleaning is required.

[0033] The heating chamber 1 is fixed above the combustion system 5 by a limiting mechanism or directly supported above the combustion system 5 by a telescopic structure 4, so that the flame of the combustion system 5 can heat the heating chamber 1. An air passage is provided between the combustion system 5 and the heating chamber 1, and a pre-reserved air duct allows air to enter the combustion system 5 to ensure normal combustion of diesel fuel.

[0034] See appendix Figure 3 The heating chamber 1 adopts an inner and outer chamber structure design, forming a cavity between the inner and outer chambers. Three layers of circulating baffles are designed along the perimeter of the chamber walls from the bottom, forming a return passage. High-temperature flue gas generated by the combustion system enters the cavity through the flue gas inlet at the bottom of the chamber body 11, flows upward along the flue gas passage, and exits from the flue gas outlet 14, ensuring that the four sides and bottom of the heating chamber 1 are heated simultaneously. The turbulence generated by the hot air flow through the flue gas passage further enhances the heat exchange between the flue gas and the chamber body 11, improving heating performance. Exhaust channels can be designed from top to bottom at the four corners of the upper part of the chamber body 11, with several small holes evenly distributed within the exhaust channels, allowing the high-temperature flue gas to exit the chamber body 11 through the exhaust gas outlets 14 at the four corners. The chamber cover 12 adopts a snap-fit ​​structure, with a sealing ring on the inner edge of the cover 12, ensuring a tight fit with the chamber body 11, extending the residence time of high-temperature steam inside the chamber, and improving the heating effect. The lid 12 has a handle 13 in the middle, which can be used to lift the lid 12.

[0035] The combustion system 5 consists of an oil supply system 7, a burner, a power supply, and a control system. The oil supply system 7 mainly consists of an oil tank 74, oil pipes 72, an oil circuit solenoid valve 73, a proportional control valve 71, and an oil level sensor 75. The oil tank 74 has an irregular shape, with an oil level sensor valve seat 75 and an oil filling port 76 located on the upper part. The oil pipe 72 connects the oil outlet of the oil tank 74, the proportional control valve 71, and the oil circuit solenoid valve 73.

[0036] When the fuel circuit solenoid valve 73 is opened, fuel is ignited under the action of low-pressure air, starting from the fuel tank 74, passing through the fuel pipe 72, and entering the fuel circuit passage of the proportional regulating valve 71. It then enters the atomizing component of the combustion system for atomization, providing conditions for ignition and combustion. By changing the opening size of the fuel circuit solenoid valve 73, the fuel supply to the system is adjusted, thereby regulating the combustion power (firepower) to meet the heating needs of food.

[0037] The combustion system 5 mainly consists of a frame 51, an air pump 56, an atomizing component, an ignition component, and a combustion cylinder 52. It achieves combustion of atomized fuel through ignition to provide heat for the fast food heating device. The frame 51 is made of aluminum alloy rectangular tubing. A base plate is set at the bottom of the frame 51, and the surrounding area is covered by a thin plate with waist-shaped holes. One of the thin plates has mounting holes for a fan, a button, and a power connector. The air pump 56, atomizing ignition, combustion cylinder 52, and other components and control system are all integrated into the frame 51.

[0038] Air pump 56 primarily provides compressed air, serving as the power source for fuel injection, atomization, and combustion air entrainment. Sufficient compressed air supply from air pump 56 ensures complete combustion. The atomization assembly employs a combined nozzle, using high-speed rotating airflow to shear and impact droplets, ensuring thorough mixing of fuel and gas before high-speed ejection from the nozzle to form an atomized fuel-gas torch. This nozzle features a large atomization cone angle, low energy consumption, and excellent atomization effect. The ignition assembly utilizes a low-pressure energy storage ignition method, rapidly raising the temperature to 1300℃ in a very short time (≤5s) for reliable ignition of the atomized fuel-gas. It exhibits good resistance to salt spray corrosion and is not prone to deformation or coking at high temperatures (1200℃).

[0039] The combustion chamber 52 mainly consists of a cylindrical combustion chamber and a radiation trap. The cylindrical combustion chamber has a porous mesh structure and employs a two-stage expansion and decompression design, which reduces the velocity of the atomized fuel gas entering the combustion chamber. This allows it to absorb more heat in a shorter stroke, rapidly vaporize, and burn, enabling the combustion chamber to quickly become a high-temperature radiator and transfer heat outwards. The radiation trap uses an inverted conical geometry with high reflectivity. The circumferential radiant heat from the combustion chamber is reflected through a reflection mechanism, concentrating and reflecting heat upwards. This reflects heat from the four directions (front, back, left, and right) of the combustion chamber upwards, forming directional radiative heat transfer with the combustion chamber, thus improving the utilization rate of combustion heat.

[0040] The power supply and control system consists of a battery, control circuit board, buttons, fan, and power connector. It provides power to the equipment and controls its operation. The battery primarily provides DC 24V power to combustion system 5; when using AC 220V to power combustion system 5, a converter is required. The control circuit board is the core component, integrating a CPU chip and various functional modules (igniter on / off control, flame detection control, solenoid valve energization control, operating status and fault control modules, etc.) and components. The operation buttons, fan, and power connector are all mounted on the same side of the frame assembly. The operation buttons control the equipment's start and stop; the fan cools the electrical components and piping, preventing damage from high temperatures that could cause malfunctions; the power connector is the equipment's power supply interface. All functional components are connected via wiring harnesses to ensure normal equipment operation.

[0041] The fast food heating device's combustion system employs pneumatic atomization ejector combustion technology, resulting in small atomized fuel particles, rapid start-up, high ignition reliability, high combustion efficiency, and fast heat transfer, while also exhibiting strong environmental adaptability. The heating chamber utilizes a return flue structure, ensuring high heat utilization. The entire unit features a modular design, making it compact, lightweight, and easy to carry.

[0042] Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention shall be included within the scope of protection of this invention.
