Description

Technical Field

[0001] This invention relates to the field of cooking apparatus technology, and more specifically, to a burner. Background Technology

[0002] The burner is the core component of a gas stove. The burner cap supplies and distributes the gas output to improve the evenness of heating the cookware above it. There are two types of burner caps: external flame and internal flame. Burners with internal flame caps are increasingly favored by consumers because they are more energy-efficient than those with external flame caps. In internal flame burners, the flame outlets are located on the inner wall of the burner cap. During cooking, the heat from the bottom of the cookware heats the surrounding gas, causing it to expand. This results in poor flame stability in that area, making it prone to flame detachment and other issues, thus affecting the burner's heating efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a burner that solves the above-mentioned technical problems.

The dividing seat includes a second gas distribution ring wall, a third gas distribution ring wall, and a connecting section connecting the second gas distribution ring wall and the third gas distribution ring wall and whose shape is adapted to the shape of the transition surface. The lower surface of the connecting section is provided with a groove penetrating the third gas distribution ring wall. The portion between the first gas distribution ring wall and the second gas distribution ring wall forms an outer ring gas groove, and the third gas distribution ring wall is connected to the central portion and forms an inner ring gas groove. The connecting section is connected to the transition surface, and the groove forms a gas distribution channel.

[0008] According to one embodiment of the present invention, the gas distribution base is provided with a connecting portion extending into the clearance hole, and the second gas distribution ring wall is provided with a docking portion corresponding to the connecting portion extending inward.

[0009] According to one embodiment of the present invention, the outer ring flame cover includes a first ring wall and a second ring wall arranged coaxially, and a connecting wall that is inclined downward from the outside to the inside and connects the upper end face of the first ring wall and the upper end face of the second ring wall. The first ring wall, the second ring wall and the connecting wall form a downward-opening gas-containing groove. The first ring wall is connected to the first gas-distributing ring wall, the second ring wall is connected to the second gas-distributing ring wall, and the gas-containing groove communicates with the outer ring gas groove.

[0031] To further understand the content, features, and effects of this invention, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0032] Please see Figure 1 and Figure 2This invention discloses a burner, including an outer ring flame cap 1, a gas distribution seat 2, and a burner head 3. The gas distribution seat 2 is installed on the top of the burner head 3, and the outer ring flame cap 1 is installed on the top of the gas distribution seat 2. The outer ring flame cap 1 includes a connecting wall 13, which is inclined and has a main flame hole 131, a first flame stabilizing channel 132, and a flame concentrating wall 133 arranged sequentially from top to bottom. The gas distribution seat 2 has an upward-opening gas groove, and an air inlet channel 21 extends downward from the bottom of the gas groove. The main flame hole 131 and the first flame stabilizing channel 132 connect the inner space of the outer ring flame cap with the gas groove. The burner head 3 has an air inlet connector 31, a mixing chamber 32, a gas delivery channel 33, and an air outlet chamber 34, and the four are connected. The air outlet chamber 34 is connected to the air inlet channel 21. The mixing chamber 32 is connected to the outside air. In use, the air inlet connector 31 is connected to an external gas pipeline. High-pressure external gas enters the air inlet connector 31 and is injected into the gas delivery channel 33. Simultaneously, external air enters the mixing chamber 32 and mixes with the gas before entering the gas delivery channel 33. The mixed gas then enters the gas delivery channel 33 and the outlet chamber 34, then the air outlet chamber and the air inlet channel 21. From the air inlet channel 21, it enters the gas groove of the gas distributor 2, and then from the gas groove, it enters the main flame port 131 and the first flame stabilizing channel 132. When the gas in the first flame stabilizing channel 132 is ignited, the flame generated by the combustion of the gas in the main burner 131 climbs along the bottom of the pot and heats the bottom of the pot; as the gas flows into the main burner 131, some of the gas enters the first flame stabilizing channel 132 to relieve pressure on the gas in the main burner 131, pulling down the root of the flame generated by the combustion of the gas in the main burner 131 to prevent the flame generated by the combustion of the gas in the main burner 131 from becoming too large; when the pot is placed on the pot rack, the flame in the main burner 131... The gas burns and heats the bottom of the cookware. The concentrating flame wall 133 reduces the space between the bottom of the cookware and the bottom of the burner's gas distribution seat. This results in less air in this space. After the cookware bottom heats the air in this space, the heat from this air is transferred to the concentrating flame wall 133, enabling it to concentrate the flame and maintain heat, thus improving the burner's heating efficiency. Furthermore, the expanded air... When the gas flows upward along the fire wall 133 to the first flame stabilizing channel 132, the temperature of the flame in the first flame stabilizing channel 132 is higher than the temperature of the air that is heated and expanded by the bottom of the pot. The first flame stabilizing channel 132 will prevent the hot air that has flowed to it along the fire wall 133 from continuing to flow upward. Therefore, the air that is heated and expanded by the bottom of the pot will not flow upward to the main burner 131 and affect the flame generated by the combustion of gas in the main burner 131. This can stabilize the flame generated by the combustion of gas in the main burner 131.

[0033] Please see Figures 1 to 3The burner of the present invention also includes an inner flame cap 4 with an inner flame hole 41, and a gas groove including an outer ring gas groove 22 and an inner ring gas groove 23. A gas distribution seat 2 is also provided with a gas distribution channel 24. An air inlet channel 21 is provided at the bottom of the outer ring gas groove 22, and the gas distribution channel 24 connects the outer ring gas groove 22 and the inner ring gas groove 23. The main flame hole 131 and the first flame stabilizing channel 132 connect the inner space of the outer ring flame cap and the outer ring gas groove 22. The inner flame cap 4 is provided on the inner ring gas groove 23, and the inner flame hole 41 is connected to the inner ring gas groove 23. After the high-pressure external combustion gas enters the intake connector 31, it is simultaneously injected into the gas delivery channel 33. At the same time, external air enters the mixing chamber 32 and mixes with the combustion gas before entering the gas delivery channel 33. The mixed gas then enters the outlet chamber 34, and from there enters the intake channel 21, and from the intake channel 21, it enters the outer annular gas groove 22. Part of the combustion gas entering the outer annular gas groove 22 enters the main burner hole 131 and the first flame stabilization channel 132, while the other part enters the distribution channel 24 from the outer annular gas groove 22, and from the distribution channel 24, it enters the inner annular gas groove 23. The gas enters the inner ring gas groove 23 and is ejected from the inner flame hole 41. When the gas is ignited, the flame of the gas burning in the inner flame hole 41 and the flame of the gas burning in the main flame hole 131 simultaneously heat the bottom of the pot, making the bottom of the pot heat up faster. Since the fire wall 133 is located between the main flame hole 131 and the inner flame hole 41, the flame of the gas burning in the inner flame hole 41 and the flame of the gas burning in the main flame hole 131 form a heat preservation layer, which has a better heat concentration effect, making the burner heat the pot more efficiently and the heat energy utilization rate higher.

[0034] In the burner of this invention, multiple main flame holes 131 are distributed along a tangential parabola of the connecting wall 13. That is, the projection of the axis of the main flame hole 131 onto the circumference of the connecting wall 13 extends along the tangent of the inner surface of the connecting wall 13. In other words, the flame formed at the outlet of the main flame hole 131 can rotate and rise circumferentially along the connecting wall 13. Multiple inner flame holes 41 are distributed along a tangential parabola of the top surface of the inner flame cover 4. That is, the projection of the axis of the inner flame hole 41 onto the circumference of the inner flame cover 4 extends along the tangent of the inner surface of the inner flame cover 4. In other words, the flame formed at the outlet of the inner flame hole 41 can rotate and rise circumferentially along the inner flame cover 4. It can be understood that the rotational rising of the inner flame hole 41 and the main flame hole 131 is beneficial for flame cohesion. During combustion, the flame burns tangentially, forming a swirling flame that converges towards the center of the burner, thereby concentrating the combustion heat, resulting in a high flame temperature and high efficiency.

[0035] Please see Figure 3The burner of the present invention includes a gas distribution base 2 comprising a gas distribution base 2a and a dividing base 2b. The gas distribution base 2a and the dividing base 2b are concentrically arranged, and the portion between the gas distribution base 2a and the dividing base 2b forms an outer annular gas groove 22. The inner ring of the dividing base 2b is provided with an inner annular gas groove 23 that communicates with the outer annular gas groove 22. After the external high-pressure gas enters the inlet connector 31, it is injected into the gas delivery channel 33 at the same time as the gas is injected into the gas delivery channel 33. External air enters the mixing chamber 32 and mixes with the gas before entering the gas delivery channel 33. The mixed gas then enters the gas delivery channel 33 and the outlet chamber 34, then enters the inlet channel 21, then the outer annular gas groove 22, and finally enters the inner annular gas groove 23 through the gas distribution channel 24 that connects the outer annular gas groove 22 and the inner annular gas groove 23.

[0036] Please see Figure 3 , Figures 7 to 9 The burner of the present invention includes a gas distribution base 2a having a bottom surface 2a1 and a first gas distribution ring wall 2a2 disposed on the outer edge of the bottom surface 2a1. The first gas distribution ring wall 2a2 extends upward from the outer edge of the bottom surface 2a1. The bottom surface 2a1 is provided with mutually symmetrical clearance holes 2a11, a central portion 2a12 disposed between the two clearance holes 2a11, and a transition surface 2a13 located between the two clearance holes 2a11 and connected to the central portion. The dividing base 2b includes a second gas distribution ring wall 2b1 and a third gas distribution ring wall 2b2. A connecting section 2b3, which connects the second gas distribution ring wall 2b1 and the third gas distribution ring wall 2b2 and whose shape is adapted to the shape of the transition surface 2a13, is provided on the lower surface of the connecting section 2b3, which has a groove penetrating the third gas distribution ring wall 2b2. The portion between the first gas distribution ring wall 2a2 and the second gas distribution ring wall 2b1 forms an outer ring gas groove 22, and the third gas distribution ring wall 2b2 is connected to the central portion 2a12 and forms an inner ring gas groove 23. The connecting section 2b3 is connected to the transition surface 2a13, and the groove forms a gas distribution channel 24. The clearance hole 2a11 allows the inner space of the outer ring burner cap 1 to communicate with the air in the gas distribution seat 2. When the gas burns in the main burner hole 131 and the inner burner hole 41, the air at the bottom of the gas distribution seat 2 can enter between the outer ring burner cap 1 and the inner burner cap 4 through the clearance hole 2a11, and the burning gas replenishes oxygen, so that the gas burns completely.

[0037] Please see Figure 3 , Figures 7 to 9 In the burner of the present invention, the gas distribution base 2a is provided with a connecting portion 2a14 extending into the clearance hole 2a11, and the second gas distribution ring wall 2b1 is provided with a docking portion 2b11 corresponding to the connecting portion 2a14 extending inward. Since the gas distribution base 2a and the dividing seat 2b are two independent parts, they are connected by the connecting portion 2a14 and the docking portion 2b11. Placing the connecting portion 2a14 in the clearance hole 2a11 can connect the two parts without affecting the gas flow direction of the outer ring gas groove 22 and the inner ring gas groove 23.

[0038] Please see Figure 2 and Figure 3 The burner of the present invention also includes a gas distributor 5, which is located at the outlet end of the air intake channel 21 and has a plurality of air holes. When the gas flows out of the air intake channel 21, it passes through the air holes on the gas distributor 5 and enters the outer annular gas groove 22, which can make the gas output from the air intake channel 21 uniform.

[0039] Please see Figures 4 to 6 The burner of the present invention includes an outer ring flame cap 1 comprising a first ring wall 11 and a second ring wall 12 arranged coaxially, and a connecting wall 13 inclined downwards from the outside to the inside and connecting the upper end faces of the first ring wall 11 and the second ring wall 12. The first ring wall 11, the second ring wall 12, and the connecting wall 13 form a downward-opening gas-receiving groove 14. The first ring wall 11 is connected to the first gas-distributing ring wall 2a2, the second ring wall 12 is connected to the second gas-distributing ring wall 2b1, and the gas-receiving groove 14 communicates with the outer ring gas groove 22. The combustion gas in the outer ring gas groove 22 enters the gas-receiving groove 14, and then enters the main flame port 131 and the first flame stabilizing channel 132 from the gas-receiving groove 14.

[0040] Please see Figure 5 and Figure 6 In the burner of the present invention, the first flame stabilizing channel 132 of the outer ring burner cap 1 includes a first flame stabilizing groove 1321 and a plurality of first flame stabilizing holes 1322. The first flame stabilizing groove 1321 extends circumferentially along the connecting wall 13 and penetrates the upper surface of the connecting wall 13. The plurality of first flame stabilizing holes 1322 are provided on the lower surface of the connecting wall 13 and are all connected to the gas receiving groove 14 and the first flame stabilizing groove 1321. When the outer ring burner cap of the present invention is used in the burner, the gas flowing out of the gas distribution seat of the burner enters the gas receiving groove 14 and then flows from the gas receiving groove 14 to the main burner hole 131. While flowing to the main burner hole 131, part of the gas enters the first flame stabilizing groove 1321 through the first flame stabilizing holes 1322 to depressurize the gas flowing to the main burner hole 131 and prevent the flame length from being too large when the gas in the main burner hole 131 is burning.

[0041] Please see Figure 5 and Figure 6In the burner of the present invention, the first flame stabilizing groove 1321 of the outer ring flame cap 1 is inclined downward from the inside to the outside, and the first flame stabilizing hole 1322 is vertically arranged along the thickness direction of the connecting wall 13. The first flame stabilizing hole 1322 is vertically arranged, which allows the gas in the gas chamber 14 to quickly enter the first flame stabilizing hole 1322 and depressurize the gas flowing towards the main burner hole 131. The first flame stabilizing groove 1321 is inclined downward from the inside to the outside, that is, the distance of the downward projection of the lower end of the first flame stabilizing groove 1321 onto the second ring wall 12 is greater than the distance of the downward projection of the upper end of the first flame stabilizing groove 1321 onto the second ring wall 12. When the gas burns in the first flame stabilizing groove 1321, the heat generated by the combustion of the gas in the first flame stabilizing groove 1321 flows upward along the upper end of the first flame stabilizing groove 1321 towards the inner ring of the outer ring burner and contacts the bottom of the pot. This can prevent the heated and expanded air from flowing upward along the fire wall 133 and continuing to flow upward at the first flame stabilizing groove 1321, so that the flame generated by the combustion of the gas in the main burner hole 131 is stable.

[0042] Please see Figure 5 and Figure 6 In the burner of the present invention, the thickness of the portion of the connecting wall 13 of the outer ring burner cap 1 that has the main flame hole 131 and the first flame stabilizing channel 132 is greater than the thickness of the flame concentrating wall 133. The greater thickness of the connecting wall 13 ensures the gas output of the main flame hole 131, while the smaller thickness of the flame concentrating wall 133 achieves the aforementioned beneficial effects while reducing the weight of the outer ring burner cap and lowering material costs.

[0043] Please see Figure 5 and Figure 6 In the burner of the present invention, the lower end of the connecting wall 13 of the outer ring burner cap 1 extends downward to form an extension wall 15. The height of the extension wall 15 near the first ring wall 11 is less than its height near the flame gathering wall 133. A first flame stabilizing hole 1322 is provided on the extension wall 15, the lower end of the first flame stabilizing hole 1322 penetrates through the extension wall 15, and the upper end of the first flame stabilizing hole 1322 communicates with the first flame stabilizing groove 1321. The lower surface of the extension wall 15 is a horizontal plane, and the air inlet ends of the first flame stabilizing holes 132 are located in the same plane. When the gas enters multiple first flame stabilizing holes 1322, the air intake is stable, so that the first flame stabilizing channel 132 provides balanced pressure relief for the gas flow entering all the main burner holes 131.

[0044] Please see Figures 4 to 6The burner of the present invention further includes a second flame stabilizing channel 121 in the outer ring flame cap 1. The second flame stabilizing channel 121 includes a second flame stabilizing groove 1211 and a plurality of second flame stabilizing holes 1212. The second flame stabilizing groove 1211 extends circumferentially along the second ring wall 12 and penetrates the inner side wall surface of the second ring wall 12. The plurality of second flame stabilizing holes 1212 are provided on the lower surface of the second ring wall 12 and are all connected to the gas receiving groove 14 and the second flame stabilizing groove 1211. When the outer ring flame cap of the present invention is used on the burner, the gas flowing out of the gas distribution seat of the burner enters the gas container 14, and then flows from the gas container 14 to the main flame hole 131. While flowing to the main flame hole 131, part of the gas enters the first flame stabilizing groove 1321 through the first flame stabilizing hole 1322, and part of the gas enters the second flame stabilizing groove 1211 through the second flame stabilizing hole 1212, so as to depressurize the gas flowing to the main flame hole 131 and prevent the flame length from being too large when the gas in the main flame hole 131 is burning. Furthermore, when the gas enters the gas container 14, since the height of the inlet end of the second flame stabilizing hole 1212 is lower than the height of the first flame stabilizing hole 1322, the gas first enters the second flame stabilizing groove 1211 through the second flame stabilizing hole 1212 for the first pressure relief, and then enters the first flame stabilizing groove 1321 through the first flame stabilizing hole 1322 for the second pressure relief. This reduces the pressure of the gas entering the main burner hole 131, preventing the gas entering the main burner hole 131 from burning for too long and causing heat energy waste.

[0045] Please see Figure 5 and Figure 6 In the burner of this invention, the second flame stabilizing groove 1211 of the outer ring burner cap 1 is horizontally arranged, and a plurality of second flame stabilizing holes 1212 are vertically arranged along the height direction of the second ring wall 12 and penetrate the lower surface of the second flame stabilizing groove 1211. The lower surface of the second ring wall 12 is a horizontal plane, and the air inlet ends of the second flame stabilizing holes 1212 are located in the same plane. When the gas enters the plurality of second flame stabilizing holes 1212, the air intake is stable. Furthermore, since the second flame stabilizing groove 1211 is horizontally arranged, when the gas burns in the second flame stabilizing groove 1211, the generated hot airflow flows along the center of the horizontal second ring wall 12 of the second flame stabilizing groove 1211. After contacting the bottom of the pot, it spreads along the bottom of the pot and heats the bottom of the pot. When the air inside the ring of the second ring wall 12 is heated by the bottom of the pot and flows upward, the hot airflow in the second flame stabilizing groove 1211 can prevent the air heated and expanded by the bottom of the pot from continuing to flow upward and affecting the stability of the flame generated by the combustion of gas in the main burner hole 131.

[0046] Please see Figures 4 to 6The burner of the present invention further includes a third flame stabilizing channel 134 in the outer ring burner cap 1. The third flame stabilizing channel 134 includes a third flame stabilizing groove 1341 and a plurality of third flame stabilizing holes 1342. The third flame stabilizing groove 1341 extends circumferentially along the connecting wall 13 and penetrates the outer side surface of the connecting wall 13. The plurality of third flame stabilizing holes 1342 are provided on the lower surface of the connecting wall 13 and are all connected to the gas receiving groove 14 and the third flame stabilizing groove 1341. The air inlet end of the third flame stabilizing hole 1342 is at the same height as the air inlet end of the main burner hole 131. After the gas in the gas receiving groove 14 is depressurized by the first flame stabilizing channel 132 and the second flame stabilizing channel 121, it is depressurized for the third time by the third flame stabilizing channel 134 when it enters the main burner hole 131. This can further ensure the stability of the gas pressure in the main burner hole 131 and ensure that the flame length of the gas in the main burner hole 131 is not too long during combustion.

[0047] Please see Figure 5 and Figure 6 In the burner of this invention, the third flame stabilizing groove 1341 of the outer ring burner cap 1 is horizontally arranged, and a plurality of third flame stabilizing holes 1342 are vertically arranged along the thickness direction of the connecting wall 13 and penetrate the lower surface of the third flame stabilizing groove 1341. When the gas in the gas container 14 enters the third flame stabilizing groove 1341 through the third flame stabilizing holes 1342 and burns in the third flame stabilizing groove 1341, the hot gas flow generated by the combustion of the gas flows outward along the third flame stabilizing groove 1341, preventing the cold air located below the third flame stabilizing groove 1341 from moving upward and affecting the stability of the flame generated by the combustion of the gas in the main burner hole 131. This also avoids reducing the flame temperature generated by the combustion of the gas in the main burner hole 131, thereby improving the thermal efficiency of the gas combustion.

[0048] Please see Figure 10 The burner of the present invention includes a burner head 3 comprising a burner head body, which is disc-shaped. A mixing chamber 32, a gas supply channel 33, and a gas outlet chamber 34 are integrated on the burner head body and protrude from the lower surface of the burner head body. An air inlet connector 31 is integrated on the side of the burner head body where the mixing chamber 32 is located and communicates with the mixing chamber 32. When the burner is installed on a stove, the mixing chamber 32 is located above the stove countertop. When the burner is working, air above the stove countertop enters the mixing chamber 32 and mixes with the gas.

[0049] Please see Figure 10In the burner of this invention, an outlet chamber 34 extends an outlet channel 35 to the upper surface of the burner head body. A mixing chamber 32 has a supporting wall 36 extending upward from the side near the outlet chamber 34. The lower surface of the gas distributor 2 is provided with a docking wall 25 corresponding to the supporting wall 36. The downward extension length of the docking wall 25 is adapted to the downward extension length of the inlet channel 21. When the gas distributor 2 is connected to the burner head 3, the inlet channel 21 docks with the outlet channel 35, and the supporting wall 36 docks with the docking wall 25, so that a gap is formed between the gas distributor 2 and the burner head 3, communicating with the inner space of the outer ring burner cap 1. When the burner is working, the air above the stove enters the mixing chamber 32 and mixes with the gas for the first time. During the combustion process, outside air enters the inner space of the outer ring burner cap 1 through the gap between the gas distributor 2 and the burner head 3, supplementing the combustion gas with oxygen and ensuring complete combustion.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
