Description

Technical Field

[0001] This utility model relates to a fuel-powered integrated stove, belonging to the field of kitchen equipment technology. Background Technology

[0002] Integrated cooktops are kitchen appliances that combine multiple functions such as range hoods, gas stoves, disinfection cabinets, and storage cabinets. They are favored by the market due to their space-saving and effective fume extraction. However, almost all integrated cooktops on the market currently use natural gas as fuel, and their operation depends on the gas pipeline network laid in cities or communities. Traditional gas integrated cooktops cannot be installed or used in rural areas, remote areas, or places where gas pipeline networks are not available, limiting their application scenarios.

[0003] Fuel oil (such as diesel and kerosene) is an ideal alternative to natural gas as it is readily available and easy to store. The core components of a fuel oil stove include an oil pump for delivering fuel and a vaporization device for atomizing or vaporizing the liquid fuel. These components generate a significant amount of heat during operation. If heat dissipation is inadequate, it will not only affect the stability and lifespan of the components, but the high-temperature flame can also cause the fuel to coke and clump within the pipes, clogging the nozzles, severely impacting combustion efficiency, and even posing safety hazards.

[0004] Therefore, how to design a fuel-powered integrated stove that combines a fuel stove and an integrated stove, which can be used independently without relying on a pipeline network, and can effectively solve the heat dissipation problem of its core components, is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this utility model is to provide a fuel-fired integrated stove that solves the problem of existing integrated stoves relying on gas pipelines and heat dissipation of key components of fuel-fired stoves.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A fuel-powered integrated stove includes a stovetop and a backsplash. The stovetop has burners equipped with a vaporization device, which is connected to an oil inlet pipe and an oil return pipe. An oil pump is installed on the oil inlet pipe. The top of the backsplash has several fume inlets, and a main air duct is located inside the backsplash. The main air duct is connected to a fan below the stovetop. The vaporization device and the oil pump are located in an equipment mounting cavity inside the stovetop. The equipment mounting cavity is connected to the outside atmosphere through an air intake duct, and the equipment mounting cavity is also connected to the main air duct inside the backsplash.

[0007] Preferably, the air inlet of the suction duct is located on the front of the stove.

[0008] The stove head described in this utility model is a recessed type, which is located in the stove platform embedded in the top surface of the stove platform.

[0009] Furthermore, several air intake holes are formed on the circumferential sidewall of the stove embedding pit, and the air intake holes are connected to the equipment installation cavity.

[0010] Preferably, a number of air intake holes are evenly distributed on the circumferential sidewall of the stove recess.

[0011] Preferably, there are two burners, and each burner has a corresponding control panel.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Integrated heat dissipation and smoke exhaust, compact and efficient structure: This utility model ingeniously combines the fan used for extracting oil fumes with the heat dissipation system of the core components. When the fan is working, it not only draws in oil fumes through the main air duct, but also draws in cool air from the outside through the suction duct. This air is forced to flow through the equipment mounting cavity containing the oil pump and vaporization device, effectively cooling the air before it is returned to the main air duct for exhaust. This design achieves "dual-purpose functionality," eliminating the need for an additional cooling fan, saving costs and internal space, and ensuring high heat dissipation efficiency and stable operation of the fuel system.

[0013] 2. Near-source exhaust gas extraction for higher combustion efficiency: By setting up a recessed stove base with air intake holes on its side wall, a negative pressure zone is created around the burner when the fan is working. This not only directly draws away exhaust gases and a small amount of oil fumes produced during combustion from the source, preventing them from escaping into the kitchen and improving smoke extraction, but also guides fresh air from the surrounding area towards the burner, providing sufficient oxygen for combustion, resulting in more complete combustion and improved thermal efficiency.

[0014] 3. Energy independence and wide applicability: This utility model uses fuel oil as fuel, eliminating the need for a gas pipeline network and requiring only an external oil drum to operate. This makes it widely applicable in rural areas, mountainous regions, field work sites, mobile food trucks, and other locations without gas supply, greatly expanding the application scope of integrated stoves.

Detailed Implementation

[0017] The present invention will be further described below with reference to specific embodiments.

[0018] The description of this utility model is merely a structural or even functional description of the embodiments, and the scope of this utility model is not limited by the embodiments described herein.

[0019] like Figures 1-6 As shown, this embodiment is achieved through the following technical solution: This utility model provides a fuel-powered integrated stove, including an integrated stovetop 5 and a vertically arranged airflow guide backplate 2 behind the stovetop 5. A disinfection cabinet 7 or other kitchen functional modules can be integrated below the stovetop 5 as needed.

[0020] The top and / or side of the backsplash 2 are provided with a fume inlet 1 for extracting cooking fumes. Inside the backsplash 2 is a main air duct (not separately labeled in the figure), the end of which is connected to a fan 8 located below the stove 5. The exhaust end of the fan 8 is connected to the outside through an air outlet 4.

[0021] Two burners 3 are mounted on the top surface of the stove 5. Each burner 3 is equipped with a fuel supply and vaporization system, which mainly includes a fuel pump 11, a fuel inlet pipe 12, a vaporization device 13, and a fuel return pipe 14. The fuel pump 11 draws fuel from an external fuel tank (not shown in the figure) and delivers it to the vaporization device 13 through the fuel inlet pipe 12. The vaporization device 13 processes the liquid fuel into easily combustible oil mist or oil vapor before supplying it to the burner 3 for combustion. Excess fuel is returned to the fuel tank through the fuel return pipe 14 to achieve pressure stabilization and flame adjustment (the return flow rate is adjustable; a larger return flow rate results in a smaller flame).

[0022] The oil pump 11, which generates significant heat, and the vaporization device 13, located near the flame, are centrally installed in a separate equipment mounting cavity 16 inside the stove 5. To dissipate heat from this cavity, an air intake duct 17 is provided, connecting to the outside atmosphere. The air inlet 6 of the air intake duct 17 is preferably located on the front of the stove 5 to facilitate the intake of cool ambient air. Meanwhile, the other end of the equipment mounting cavity 16 is connected to the main air duct within the guide plate 2 via a transition air duct 15.

[0023] In this embodiment, the burner head 3 is designed as a recessed structure, that is, it is located in the burner mounting pit 9 formed by the recess on the top surface of the burner 5. A number of air intake holes 10 are evenly opened on the circumferential side wall of the burner mounting pit 9. These air intake holes 10 are connected to the equipment mounting cavity 16 through pipes or directly.

[0024] The overall workflow of the machine is as follows: The user starts the stove via control panel 18. Oil pump 11 and gasification device 13 begin operating, supplying fuel to burner 3 and igniting it. Simultaneously, fan 8 starts running.

[0025] The operation of fan 8 generates a strong suction force, forming two parallel airflow paths: Path 1: Smoke exhaust path: Cooking fumes and some combustion exhaust gases are drawn into the main air duct by the smoke inlet 1 on the guide back plate 2.

[0026] Path Two: Heat Dissipation and Auxiliary Smoke Exhaust Path. Ambient air from the outside is drawn into the equipment mounting cavity 16 through the air inlet 6 and the suction duct 17. The airflow passes over the surfaces of the oil pump 11 and the vaporization device 13, and through forced convection, carries away the heat generated by these two components during operation, achieving effective cooling. The air carrying heat then flows into the main air duct through the transition air duct 15. Simultaneously, since the equipment mounting cavity 16 is connected to the suction hole 10, the suction force of the fan 8 also acts on the suction hole 10 in the stove embedment pit 9, directly drawing the exhaust gas generated by the combustion of the burner 3 into the equipment mounting cavity 16 from the source, and then into the main air duct. At the same time, the negative pressure also guides the surrounding fresh air towards the burner 3, providing sufficient oxygen for combustion, making combustion more complete, and improving thermal efficiency.

[0027] Ultimately, the airflow from the two paths—oil fumes, exhaust gas, and cooling air—mixes in the main duct, is pressurized by the fan 8, and is discharged outdoors through the outlet 4.

[0028] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
