Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to a stove base and a stove combustion head. Background Technology

[0002] Currently, gas stoves are widely used. Their main working principle is to guide gas through a gas pipe to the burner head of the stove, where it mixes with air to form a combustible mixture, which is then ignited. The burner cap, which covers the burner head, then guides the gas to burn evenly, resulting in a uniform flame.

[0003] To ensure even flame distribution both inside and outside the burner head during combustion, gas channels are typically installed inside the burner base. This allows gas to enter the internal and external gas channels separately, with the burner caps covering each channel to achieve separate flame distribution. However, since gas is generally introduced directly into the gas channels through vents, areas closer to the vents may have more gas, while areas farther away may have less, resulting in an uneven flame. Furthermore, incomplete combustion can also occur after the gas enters. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a stove base and a stove burner head, which can guide gas into the stove through the middle gas guide section, guide the gas to the outer burner head for combustion through the side gas guide section, and guide the gas to the middle burner head through the second gas guide groove connected to the middle gas guide section, so as to achieve uniform distribution of gas inside and outside; and guide the gas with the inclined slope to guide the gas to diffuse and divert, thereby improving the gas combustion efficiency.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A furnace base is provided with an air inlet channel, a first air guide groove, and a second air guide groove. The first air guide groove includes a middle air guide section and a side air guide section. The side air guide sections are connected to both sides of the middle air guide section. The air inlet channel communicates with the middle air guide section. The side air guide sections and the second air guide groove gradually slope upward from the end near the air guide cavity to the end away from the middle air guide section.

[0007] Furthermore, the intermediate air guide section and the side air guide section are connected by an arc surface.

[0008] Furthermore, the side gas guide section extends circumferentially along the furnace base.

[0009] Furthermore, the side gas guide sections are connected to both sides of the intermediate gas guide section, and the side gas guide sections and the intermediate gas guide section extend along the circumference of the furnace base.

[0010] Furthermore, a baffle section is provided at the top of the first air guide groove, and the baffle section surrounds the top of the first air guide groove.

[0011] Furthermore, the second air guide groove extends to the middle end of the baffle section.

[0012] Furthermore, the furnace base is provided with an annular gas mixing groove in the middle; one end of the second gas guiding groove extends through the middle gas guiding section, and the other end of the second gas guiding groove extends through the annular gas mixing groove.

[0013] Furthermore, the annular mixing groove is provided with a number of first positioning ribs on its peripheral wall.

[0014] Furthermore, the inner peripheral wall of the first air guide groove is provided with a second positioning rib, which is located at the connection position between the middle air guide section and the side air guide section; the second positioning rib is an arc rib.

[0015] A stove burner head includes a stove base and a burner cap, the burner cap covering the top of the first gas guide groove and the second gas guide groove of the stove base.

[0016] In summary, this utility model has the following technical effects:

[0017] 1. The combustible gas in the side air guide section and the second air guide groove is guided upward by the inclined wall. When the gas flows on the inclined surface, a thin gas film will form on its surface, which will fully contact the air. This will help the gas and air mix better, improve the combustion efficiency of the outer and middle burner caps, reduce the emission of harmful gases, and make the flame more stable.

[0018] 2. Combustible gas flows from the middle gas guide section into the side gas guide section and the inclined surface of the second gas guide groove, which can carry out preliminary diffusion and diversion before reaching the burner cap, avoiding the gas from concentrating in a certain area, thereby making the flame evenly distributed on the burner cap and improving combustion efficiency.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] Example 1,

[0027] See Figure 1 and Figure 2 This utility model discloses a furnace base 10, which is provided with an air inlet channel 17, a first air guide groove and a second air guide groove 13. The first air guide groove includes a middle air guide section 11 and a side air guide section 12, and the side air guide section 12 is connected to both sides of the middle air guide section 11, connecting the air inlet channel 17 and the middle air guide section 11. The air inlet channel 17 can guide combustible gas into the middle air guide section 11, while the side air guide section 12 and the second air guide groove 13 are both inclined upwards from the end near the air guide cavity to the end away from the middle air guide section 11.

[0028] Based on the above structure, when using the stove base 10 of this utility model, the stove base 10 can be used in a gas stove. When guiding the gas in, the gas pipeline can mix the gas with air to form a combustible gas, which is guided through the air inlet channel 17 to the middle air guide section 11 of the first air guide groove. Since the middle air guide section 11 is located in the middle of the first air guide groove, the combustible gas can partially flow to the side air guide section 12 and be discharged to the outer burner cap 20, while part of it is discharged to the middle burner cap 20 through the middle second air guide groove 13.

[0029] During the process of being directed to the burner cap 20, the combustible gas in the side guide section 12 is guided upward by the inclined wall. When the gas flows on the inclined surface, a thin gas film is formed on its surface, which is in full contact with the air. This facilitates better mixing of the gas and the air, improves the combustion efficiency of the external burner cap 20, reduces the emission of harmful gases, and makes the flame more stable.

[0030] Similarly, the combustible gas in the second gas guide groove 13 in the middle can also be guided upward through the inclined wall. When the gas flows on the inclined surface, a thin gas film will form on its surface, which will fully contact the air and facilitate better mixing of the gas and air. This can improve the combustion efficiency of the middle burner cap 20, reduce the emission of harmful gases, and make the flame more stable.

[0031] In addition, the combustible gas flows from the middle gas guide section 11 into the side gas guide section 12 and the inclined surface of the second gas guide groove 13, which can carry out preliminary diffusion and diversion before reaching the burner cap 20, avoiding the gas from concentrating in a certain area, thereby making the flame evenly distributed on the burner cap 20 and improving the combustion efficiency.

[0032] Furthermore, the intermediate gas guide section 11 and the side gas guide section 12 are connected by an arc surface. This allows the combustible gas in the intermediate gas guide section 11 to enter the side gas guide section 12, where the arc surface provides a smooth transition. The relatively smooth arc surface provides gentler contact with the gas, enabling the gas to flow smoothly along its surface. Compared to transitions using sharp corners or flat surfaces, this significantly reduces airflow separation and turbulence, thereby lowering flow resistance and improving gas transmission efficiency. Reducing resistance during gas flow ensures smooth gas flow.

[0033] Furthermore, the side gas guide section 12 extends circumferentially along the furnace base 10. Thus, when the combustible gas flows within the side gas guide section 12, the combustible gas can flow upward from the slope and be evenly distributed circumferentially on the burner cap 20. In this way, the combustible gas can be evenly guided to the outer burner cap 20 to achieve uniform combustion.

[0034] Furthermore, both sides of the intermediate gas guide section 11 are connected to side gas guide sections 12. The side gas guide sections 12 on both sides and the intermediate gas guide section 11 extend along the circumference of the furnace base 10. In this way, the combustible gas entering the intermediate gas guide section 11 can flow from the middle toward the side gas guide sections 12 on both sides, and be guided upwards to the outer burner cover 20 on both sides. Thus, the combustible gas entering the outer burner cover 20 is guided by both sides at the same time, and the combustible gas distributed throughout the entire outer burner cover 20 flows evenly, without uneven distribution caused by the introduction from one side.

[0035] Furthermore, a baffle section 15 can be provided at the top of the first gas guide groove. The baffle section 15 surrounds the top of the first gas guide groove. After the outer flame cap 20 is sealed above the first gas guide groove, the baffle section 15 can extend upward to surround the outer flame cap 20. This can prevent the combustible gas in the first gas guide groove from overflowing and reduce the backfire caused by the overflow of combustible gas.

[0036] More specifically, the second gas guide groove 13 extends to the middle end of the baffle section 15, so that the combustible gas in the middle gas guide section 11 can flow upward and enter the second gas guide groove 13 through the middle end of the baffle section 15, increasing the flow time of the combustible gas in the middle gas guide section 11. The gas can be fully mixed in the middle gas guide section 11 before entering the second gas guide groove 13, thus making the combustion more complete.

[0037] Furthermore, an annular mixing groove 14 can be provided in the middle of the furnace base 10, and one end of the second gas guiding groove 13 extends to the middle gas guiding section 11, while the other end of the second gas guiding groove 13 extends to the annular mixing groove 14. Based on this structure, after the combustible gas in the middle gas guiding section 11 enters the second gas guiding groove 13, it can be further guided to the annular mixing groove 14. In other words, the combustible gas can be guided to flow in an annular pattern on the inner circumferential wall of the annular mixing groove, achieving thorough re-mixing and more complete combustion of the gas at the position of the middle burner cap 20.

[0038] More specifically, a number of first positioning ribs 141 can be provided on the peripheral wall of the annular mixing groove 14. When the intermediate flame cap 20 is sealed to the annular mixing groove 14, the number of first positioning ribs 141 can be inserted into the positioning post of the intermediate flame cap 20, assembled with the connecting screw of the intermediate flame cap 20, or abutted against the limiting post of the intermediate flame cap 20, thereby realizing the assembly limitation of the intermediate flame cap 20, preventing the flame cap 20 from shifting during use, and ensuring the stable assembly of the flame cap 20 structure.

[0039] Furthermore, a second positioning rib 16 can be provided on the inner peripheral wall of the first air guide groove. The second positioning rib 16 is located at the connection position between the middle air guide section 11 and the side air guide section 12. Several second positioning ribs 16 can be inserted into the positioning post of the outer flame cap 20, or assembled with the connecting screw of the outer flame cap 20, or abutted against the limiting post of the outer flame cap 20, thereby realizing the assembly limitation of the outer flame cap 20, preventing the flame cap 20 from shifting during use, and ensuring the stable assembly of the flame cap 20 structure.

[0040] The second positioning rib 16 is an arc rib. When the combustible gas in the middle air guide section 11 is guided to the side air guide section 12 for transition, the arc outer surface of the arc rib is used for smooth guidance, reducing the instability of airflow at the corner position.

[0041] Example 2,

[0042] See Figure 1 , Figure 2 as well as Figure 3 The stove burner head shown includes a stove base 10 and a burner cap 20 as described in Embodiment 1, with the burner cap 20 covering the top of the first gas guide groove and the second gas guide groove 13 of the stove base 10.

[0043] When the gas is introduced, the gas pipeline can mix with air to form a combustible gas, which is then guided through the air intake channel 17 to the middle air guide section 11 of the first air guide groove. Since the middle air guide section 11 is located in the middle of the first air guide groove, part of the combustible gas can flow to the side air guide section 12 and be discharged to the outer burner cap 20, while part of it is discharged to the middle burner cap 20 through the middle second air guide groove 13.

[0044] During the process of being directed to the burner cap 20, the combustible gas in the side guide section 12 is guided upward by the inclined wall. When the gas flows on the inclined surface, a thin gas film is formed on its surface, which is in full contact with the air. This facilitates better mixing of the gas and the air, improves the combustion efficiency of the external burner cap 20, reduces the emission of harmful gases, and makes the flame more stable.

[0045] Similarly, the combustible gas in the second gas guide groove 13 in the middle can also be guided upward through the inclined wall. When the gas flows on the inclined surface, a thin gas film will form on its surface, which will fully contact the air and facilitate better mixing of the gas and air. This can improve the combustion efficiency of the middle burner cap 20, reduce the emission of harmful gases, and make the flame more stable.

[0046] In addition, the combustible gas flows from the middle gas guide section 11 into the side gas guide section 12 and the inclined surface of the second gas guide groove 13, which can carry out preliminary diffusion and diversion before reaching the burner cap 20, avoiding the gas from concentrating in a certain area, thereby making the flame evenly distributed on the burner cap 20 and improving the combustion efficiency.

[0047] It should be noted that the other structures of the stove burner head in this embodiment are the same as those in the prior art, and will not be described in detail here.

[0048] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
