Description

Technical Field

[0001] This utility model relates to the field of gas furnace technology, specifically to a commercial energy-saving gas furnace burner head. Background Technology

[0002] Currently, the stoves used in restaurants and canteens rely on the cooperation of a ignition tube and an ignition needle to achieve ignition. After successful ignition, the main air intake valve is opened to allow gas to flow in, igniting the ignition tube for stir-frying and other cooking operations. In actual use, the main air intake pipe, ignition tube, and ignition needle are located at the bottom of the inner burner core. The main air intake pipe and ignition tube are separate. During ignition, the gas drawn from the ignition tube needs to mix with air in the inner burner core to achieve a suitable air-fuel ratio before it can be ignited by the ignition needle. Then, the main air intake valve is opened, allowing the ignition tube to ignite the gas drawn from it. During the ignition process, after the ignition needle is activated, it takes several seconds or even longer for the gas from the ignition tube to mix with the air in the inner burner core before the ignition tube can be lit. This makes rapid ignition impossible. At the same time, because the density of gas is less than that of air, the gas rises during ignition and easily dissipates into the air, producing a pungent odor and affecting the user experience. Meanwhile, most commercial gas stoves currently use a premixed combustion method, which involves introducing gas and air into the cavity between the inner and outer furnace cores to form a mixed combustible gas. In actual use, chefs need to adjust both the gas intake and the air volume. During use, chefs need sufficient experience to precisely control the ratio of gas to air to achieve better combustion results, thereby ensuring firepower while saving gas. This makes current commercial gas stoves inconvenient to use. Utility Model Content

[0009] Furthermore, the air inlet assembly includes a first air inlet, a second air inlet, and a third air inlet. The first air inlet, the second air inlet, and the third air inlet are all disposed on the upper part of the inner furnace core sidewall. Multiple first air inlets are provided, each circumferentially disposed on the inner furnace core sidewall.

[0013] Furthermore, the upper edge of the annular support platform is provided with a support edge for supporting the stove, and an insulation layer is provided inside the annular support platform.

[0014] The beneficial effects of this utility model are:

[0015] This utility model's commercial energy-saving gas stove burner head utilizes a unique integrated gas input component design to achieve integrated input of both ignition gas and main gas. During ignition, the ignition gas is directly delivered to the gas port of the flame suppressor cap via the integrated gas input component and is rapidly ignited by the ignition needle to form a flame. This design avoids the lengthy process of gas mixing with air in the inner furnace core of traditional gas stoves, eliminating the need to wait for the gas and air to reach a suitable air-fuel ratio before ignition. This significantly shortens ignition time, achieving rapid ignition and improving the efficiency of the gas stove, making it particularly suitable for commercial kitchens requiring quick meal preparation. In traditional gas stoves, because the gas density is less than air, the gas easily rises and dissipates into the air during ignition, producing a pungent odor that not only affects the user experience but also poses safety hazards. This utility model's flame suppressor cap design, with gas ports on its outer wall, allows for precise control of the gas flow direction and flow rate. During ignition, the ignition gas flows out in an orderly manner through the gas holes of the burner cap and is ignited, effectively reducing gas escape during ignition, avoiding the generation of pungent odors, improving the kitchen environment, and reducing gas waste and safety hazards. Existing commercial gas stoves mostly use premixed combustion, requiring chefs to simultaneously adjust the air intake and air volume to precisely control the gas-air ratio, which demands a high level of experience and is relatively cumbersome. This utility model's commercial energy-saving gas stove burner head inputs air at a constant flow rate into the air chamber through an air supply device, while the integrated gas input component ensures a stable gas input, resulting in a relatively stable gas-air mixture ratio. In practical use, chefs do not need to frequently adjust the air intake and air volume as with traditional gas stoves; they only need to simply adjust the main gas flow rate through the main gas volume regulating valve, greatly reducing operational difficulty and improving ease of use.

[0016] Furthermore, because the air supply device ensures a constant airflow velocity into the air chamber, and the integrated gas input component stably supplies gas, the gas and air can be fully and evenly mixed within the air chamber and the inner furnace core. This stable mixing ratio ensures complete combustion of the gas, improves thermal efficiency, reduces gas waste, and achieves energy conservation. The flame-gathering ring at the top of the inner furnace core, with its frustum-shaped structure and upward-extending flame outlet, concentrates the flame, further increasing the flame temperature and combustion efficiency. This allows the gas stove to generate more heat with the same gas consumption, meeting the high-heat cooking needs of commercial kitchens.

[0017] Furthermore, the air inlet pipe of this invention adopts an L-shaped design, including a vertical pipe and a horizontal pipe, both of which are integrally formed with the outer furnace core. This integrally formed structure not only enhances the overall stability of the air inlet pipe and reduces the risk of leakage at the connection points, but also improves the overall strength and durability of the gas furnace. Simultaneously, the air cavity design between the inner and outer furnace cores is reasonable, and the circumferentially staggered arrangement of the air inlet hole components allows air to enter the inner furnace core evenly and smoothly, ensuring thorough mixing of gas and air, and further improving the combustion performance and stability of the gas furnace.

[0030] like Figure 1-9 As shown, the commercial energy-saving gas stove burner head of this utility model mainly includes an annular support platform 1, an outer furnace core 2, an inner furnace core 3, a flame cap 4, an ignition needle 5, and a gas integrated input component 6.

[0031] Figure 1 As shown, the annular support platform 1 serves as the supporting foundation for the entire gas stove.

[0034] Figure 5 and Figure 8As shown, the burner cap 4 is located at the bottom of the inner furnace core 3. The outer wall of the burner cap 4 has a gas hole 41. The ignition gas input from the gas integrated input component 6 is fed into the inner furnace core 3 through the gas hole 41 and ignited by the ignition needle 5 to form a ignition source. The design of the burner cap 4 allows control over the direction and flow rate of the gas, enabling rapid accumulation of gas within the burner cap during ignition, thus achieving rapid ignition and contributing to the stable formation of the ignition source.

[0035] The ignition needle 5 is used to ignite the spark gas. Its position corresponds to the gas output position of the flame cap 4 to ensure accurate ignition of the gas.

[0036] Figures 3-5 As shown, the gas integrated input component 6 is installed in the air inlet pipe 7 for inputting ignition gas and main gas, and is connected to the main gas flow regulating valve 65 for easy adjustment of the main gas flow rate. The air inlet pipe 7 is connected to an air supply device, which is used to input air at a constant flow rate into the air chamber 8 to ensure a stable mixing ratio of gas and air.

[0037] Figure 3 As shown, the integrated gas input assembly 6 includes a gas input pipe 61, a tee 62, a ignition gas pipe 63, and a main gas pipe 64. The gas input pipe 61 is installed in the air inlet pipe 7, with its upper end located in the area covered by the burner cap 4 at the bottom of the inner furnace core 3, and its lower end located outside the air inlet pipe 7. One end of the tee 62 is connected to the lower end of the gas input pipe 61, and the ignition gas pipe 63 and the main gas pipe 64 are respectively connected to the other two ends of the tee 62. The main gas flow regulating valve 65 is connected to the main gas pipe 64.

[0038] During installation, the bottom of the vertical pipe 71 of the air inlet pipe 7 is provided with a first fixing hole 711, and the bottom of the inner furnace core 3 is provided with a second fixing hole 31. The gas input pipe 61 is arranged in the vertical direction, with its upper end fixed in the second fixing hole 31 and its lower end fixed in the first fixing hole 711. This fixing method ensures the stability of the gas input pipe 61 and ensures that the gas can be smoothly input into the inner furnace core 3.

[0039] A groove 32 for placing the burner cap 4 is provided in the middle of the bottom of the inner furnace core 3. The burner cap 4 is placed in the groove 32, and the second fixing hole 31 is located in the groove 32. A third fixing hole 33 is provided on the outside of the groove 32 at the bottom of the inner furnace core 3, and a fourth fixing hole 21 is provided on the outer furnace core 2 corresponding to the third fixing hole 33. The ignition needle 5 is installed through the third fixing hole 33 and the fourth fixing hole 21. This structural design allows the ignition needle 5 to accurately extend into the inner furnace core 3 and ignite the ignition gas flowing out of the gas hole 41 of the burner cap 4.

[0040] Figure 6 and Figure 7As shown, the air inlet assembly 9 includes a first air inlet 91, a second air inlet 92, and a third air inlet 93, all of which are located on the upper part of the side wall of the inner furnace core 3. Multiple first air inlets 91 are provided, each circumferentially arranged on the side wall of the inner furnace core 3; multiple second air inlets 92 are provided, each circumferentially arranged on the side wall of the inner furnace core 3; and multiple third air inlets 93 are provided, each circumferentially arranged on the side wall of the inner furnace core 3. The first and second air inlets 91 and 92 are staggered vertically, as are the second and third air inlets 93. This staggered arrangement increases the uniformity of air entering the inner furnace core 3, allowing for better mixing of fuel gas and air.

[0041] Furthermore, a flame-gathering ring 34 is provided at the top of the inner furnace core 3. The flame-gathering ring 34 is a frustum-shaped cone arranged in the vertical direction, with its side walls inclined and its inner diameter decreasing from bottom to top. A fire outlet 341 is provided at the top of the flame-gathering ring 34. The fire outlet 341 is circular and extends upward. The design of the flame-gathering ring 34 can concentrate the flame, improving the flame temperature and combustion efficiency.

[0042] To further optimize the air intake effect of the inner furnace core 3, the air inlet assembly 9 also includes a fourth air inlet 94. A ramp 35 is circumferentially arranged on the top of the side wall of the inner furnace core 3, with the ramp 35 located on the inner side of the side wall. The fourth air inlet 94 is circumferentially positioned on the ramp 35 and faces the flame-gathering ring 34. This allows air to enter the flame-gathering ring 34 area more smoothly and mix thoroughly with the fuel gas.

[0043] The air supply device includes a blower (not shown in the figure), which is connected to the air inlet pipe 7. The blower is used to input air at a constant flow rate into the air inlet pipe 7. The blower can be adjusted according to the usage requirements of the gas furnace to ensure a constant air flow rate into the air chamber 8, thereby achieving a stable mixing of gas and air.

[0044] Working principle:

[0045] When using the commercial energy-saving gas stove burner head of this utility model, firstly, gas is input through the gas integrated input component 6. The ignition gas flows from the gas hole 41 of the burner cap 4 into the inner furnace core 3 via the ignition gas pipe 63, the tee 62, and the gas input pipe 61. At this time, the ignition needle 5 is activated, igniting the ignition gas flowing from the gas hole 41 of the burner cap 4, forming a ignition source. Next, the main gas flows from the gas hole 41 of the burner cap 4 into the inner furnace core 3 via the main gas pipe 64, the tee 62, and the gas input pipe 61. Simultaneously, the blower of the air supply device is activated, inputting air at a constant flow rate into the air inlet pipe 7. The air enters the air chamber 8 through the air inlet pipe 7, and then enters the inner furnace core 3 through the air inlet hole component 9 on the side wall of the inner furnace core 3. The gas mixes with the air entering the inner furnace core 3 to form a mixed combustion gas. The mixed combustion gas is ignited by the ignition source, forming a stable flame. Because the air supply device ensures a constant airflow velocity into the air chamber 8, and the design of the air inlet assembly 9 allows air to enter the inner furnace core 3 evenly, the mixing ratio of gas and air is stable, resulting in good combustion. Simultaneously, during ignition, gas can quickly accumulate in the flame suppressor, eliminating the need to wait for a prolonged mixing time between gas and air in the inner furnace core 3, thus achieving rapid ignition.
