DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of the present application clearer and more apparent, the present application will be further described in detail below in combination with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0041] In the actual application of commercial gas stoves, the traditional products often have problems of disordered exhaust flow field, insufficient mixing of gas and air, and low combustion efficiency. The existing hearths mostly adopt single-hole exhaust, which leads to uneven force on the flame, high-temperature vortex in some areas, and serious heat loss. At the same time, since the gas and air are not fully mixed before entering the combustion zone, incomplete combustion is prone to occur, thereby bringing technical bottlenecks of reduced energy efficiency and unstable emission.

[0042] The present application forms an optimized exhaust passage by setting multiple groups of circular and long-strip-shaped exhaust holes at the top of the hearth, and realizes orderly guidance of the flame flow field. The structure is verified by numerical simulation and experiment, and while maintaining the stability of the flame, reduces the invalid loss of heat to the outside, and improves the overall thermal efficiency of the hearth. Compared with the single-hole design, the exhaust layout effectively disperses the heat flux density, avoids local overheating, and improves the reliability of the equipment in the high-frequency commercial environment.

[0043] In the gas delivery link, the traditional straight pipe structure is easy to cause uneven flow distribution, affecting the uniformity of gas and air mixing. The present application adopts a certain angle of elbow pipe design in the furnace head gas delivery pipe, so that the gas flow is more in line with the characteristics of fluid dynamics, so as to obtain better flow rate and direction before entering the premix interface. This optimization lays the foundation for the subsequent rapid mixing of gas and air, and plays a key role in stabilizing the flame shape.

[0044] In the premixing system, the present application introduces a manifold structure with resonance function. Through the coupling design of the fan outlet and the premixing interface air inlet, the resonance effect is used to enhance the air inertia in a certain speed range, and to promote the uniform mixing of gas and air in a very short distance. Compared with the existing straight-through mixer, this premixing system can significantly improve the combustion efficiency, ensure that the gas stove still maintains stable heat power output and low emission level under high load operation.

[0045] In the safety control layer, the present application synchronizes the gas start-stop and ignition process through the linkage design of the gas valve and the igniter. The traditional gas stove has the hidden danger of ignition delay and gas leakage, while the present scheme realizes the real-time coordination of gas supply and ignition action, thereby effectively avoiding the occurrence of dangerous situations. This mechanism is particularly critical in commercial places, ensuring that the equipment can still maintain safe and reliable operation under high-frequency start-stop conditions.

[0046] The present application realizes the comprehensive progress of improving combustion efficiency, increasing energy utilization rate, enhancing operation safety and reducing maintenance cost through the optimization of furnace exhaust structure, improvement of gas delivery path, coupling design of premix manifold and linkage control mechanism. This technical solution not only breaks through the limitations of existing commercial gas stoves, but also shows good popularization prospect in industrial application, and can meet the urgent needs of the catering industry for efficient, stable and safe combustion equipment.

[0047] As shown in Figure 1 The present application provides a simple table-embedded commercial gas stove, which comprises a stove main body, a gas system and a safety control system.

[0048] The whole stove body 1 is a rectangular frame, including a hearth 11, a first dual-purpose support 12, a second dual-purpose support 13, a burner 2, a gas stove handrail 31 and a gas stove switch 32. The hearth 11 is made of high-temperature-resistant cast iron, and the exhaust holes are circular and long strip-shaped exhaust holes arranged uniformly. The circular exhaust holes have a diameter of 2 mm, and the exhaust holes are arranged in a circle in a group of 48. There are three groups of prototype exhaust holes and one group of long strip-shaped exhaust holes, which are uniformly distributed on the top of the hearth. The optimized exhaust flow field reduces heat loss and improves thermal efficiency. The first dual-purpose support 12 and the second dual-purpose support 13 are made of 304 stainless steel, which takes into account the load bearing and heat dissipation. The burner 2 includes a gas outlet hole 21, a burner inner wall 22, a burner gas delivery pipe 23, a small-flow gas inlet 24, an air inlet 25 and an igniter 26.

The gas premixing interface 6 includes one gas inlet 61 and three gas outlets 62, which are located at the fan outlet 53. The premixing pipe has a diameter of 14 mm and is uniformly distributed on the pipe wall. This structure adopts a manifold design. The resonance intake manifold uses the resonance principle to generate intake resonance within a specific speed range, enhancing intake inertia and improving intake efficiency. It ensures that the gas entering the inlet 61 is evenly distributed to the three outlets 62, maintaining consistent mixing and combustion effects. The gas premixing pipeline can shorten the mixing distance to ensure that the gas-air reaches a uniform mixing state in a very short distance, ultimately achieving efficient and stable combustion.

[0050] The burner structure includes hearth 21 exhaust hole shape, size and number optimized by numerical simulation and experiment, circular and long strip-shaped exhaust holes arranged uniformly, circular exhaust hole diameter 8mm, exhaust hole number 48 in a group arranged in a circle, prototype exhaust hole total 3 groups, long strip-shaped exhaust hole 1 group, uniformly distributed on the top of the hearth, optimized exhaust flow field, reduced heat loss, improved thermal efficiency.

[0051] The gas stove adopts modular design, and the core components such as hearth 11, burner 2, small high-speed fan 5, large-flow gas valve 4 and gas premixing interface 6 can be independently disassembled and replaced, reducing maintenance time by 50% and significantly reducing maintenance cost.

[0052] The high-efficiency premixed air-adaptive commercial gas stove provided by the embodiments of the present application realizes efficient combustion, energy-saving control, and safety control. First, the design of the stove body ensures the durability and easy cleaning of the overall structure. The stove head and the burner head are made of cast iron material, which can withstand high temperature and corrosion, so that the system can still operate stably in a high-temperature environment.

[0053] The commercial gas stove of the present application optimizes the mixing process of gas and air, combines advanced safety control mechanisms, not only improves the combustion efficiency and heat energy utilization rate, but also makes significant improvements in user safety. The design of the present application enables the system to provide stable, efficient, and safe combustion effect in actual use, and is suitable for various commercial kitchen scenes.
