Description

A gas burner for a wok with high thermal efficiency Technical Field

[0001] This invention relates to the field of burner technology, specifically to a gas burner for a wok with high thermal efficiency. Background Technology

[0002] As a type of combustion equipment, wok burners come in various types. They can be classified by fuel type, such as oil (e.g., diesel) burners and gas (e.g., natural gas, liquefied petroleum gas) burners. Among them, gas burners are currently the mainstream type and are suitable for commercial kitchens (e.g., restaurants, hotels), food processing plants, etc. Especially for commercial places such as restaurants and hotels, in order to speed up the food service, they usually choose burners with higher heat output, which requires a larger amount of gas. At the same time, they are equipped with auxiliary equipment such as blowers to provide more air simultaneously, so the thermal efficiency requirements of the burners are higher.

[0003] For example, Chinese patent CN114593419A discloses a low-NOx burner based on flue gas internal circulation. In this type of burner, the gas is delivered to the furnace through two paths, and the air is also delivered to the furnace through two paths. By sending both gas and air into the furnace through two paths, the gas and air delivered to the gas cavity and the air cavity respectively are fully mixed before reaching the furnace, thereby improving the combustion efficiency of the burner.

[0004] However, in existing burners, when the gas jet carries air along with it for mixing, the size of the air path is often fixed. This means that when the gas jet size is changed to adjust the flame size, the air in the air path is always entrained at a fixed opening size (although the air is passively entrained into the gas, the size of the air path opening is still an important factor affecting the air intake). As a result, the gas and air mixture often cannot achieve a uniform mixing state, leading to an imbalance in the gas-air mixture ratio and incomplete combustion. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a gas burner for a wok with high thermal efficiency, solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gas burner for a wok with high thermal efficiency, comprising: a burner head; a burner sleeve, the burner sleeve being disposed below the burner head and forming a gas flow channel between the burner head and the burner head; a gas chamber, the gas chamber being located at the bottom of the gas flow channel and having a gas flow passage opened circumferentially, and a premixing chamber being formed at the top of the gas flow channel; an air chamber, the air chamber being located above the gas chamber and having an air flow passage opened circumferentially, wherein a gas jet in the gas chamber entrains air in the air chamber and flows together into the premixing chamber; an annular valve plate is disposed above the gas flow passage, the annular valve plate being capable of closing the air flow passage in a normally closed state; and a pressure component, the pressure component being located below the annular valve plate, used to control the opening size of the annular valve plate on the air flow passage, so that the gas and air are quantitatively mixed and delivered to the premixing chamber.

[0007] Furthermore, the pressure assembly includes: a piston located inside the gas chamber, the piston being capable of moving downward in response to gas delivery pressure; a first guide ring located on the piston; and an annular valve plate including a first annular valve plate disposed above the first guide ring.

[0008] Furthermore, the pressure assembly also includes: a second magnetic ring located below the piston; and a first magnetic ring located below the second magnetic ring, wherein the first magnetic ring and the second magnetic ring are magnetically repelled to form a deformation space, providing downward displacement clearance for the piston when subjected to force.

[0009] Furthermore, the pressure assembly also includes: a second impeller, which is rotatably mounted on the piston and rotates in response to the impact of the gas jet; and a first drive shaft, which is located in the middle of the second impeller and extends into the premixing chamber, capable of responding to the synchronous rotation and downward movement of the second impeller to generate a driving force for the gas to be mixed with air and then discharged.

[0010] Furthermore, the pressure assembly includes: a fourth impeller rotatably mounted inside the gas chamber, rotating in response to the impact of the gas jet; a second drive shaft slidably engaged with the middle of the fourth impeller, rotating synchronously in response to the rotation of the fourth impeller and capable of moving downward along its axial direction; and an annular valve plate including a second annular valve plate rotatably mounted on the second drive shaft.

[0011] Furthermore, the pressure assembly also includes: a power generation coil, which is located at the bottom end of the second drive shaft and generates electricity in response to the rotation of the second drive shaft; an electromagnet, which is located above the power generation coil; and an armature ring, which is rotatably mounted on the second drive shaft and positioned opposite the electromagnet. When the power generation coil generates electricity to energize the electromagnet, it generates a magnetic attraction force that drives the armature ring to move closer to the electromagnet, thereby generating a driving force that drives the second drive shaft to move downward.

[0012] Furthermore, the second drive shaft extends into the premixing chamber and is able to generate a driving force to drive the combustion gas and air to mix and be discharged in response to the rotation drive of the fourth impeller and the downward drive of the armature ring.

[0013] Furthermore, it also includes: a first impeller, which is rotatably mounted inside the air chamber, capable of rotating in response to the air jet, and forming an air passage for airflow on one side of the blades of the first impeller; and a second guide ring, which is disposed on the blades of the fourth impeller, forming a gas passage for gas flow between the second guide ring and the fourth impeller, and between the first guide ring and the second impeller.

[0014] Furthermore, it also includes: an outer combustion ring, which is located at the edge of the burner head and forms a second gas supply chamber with the burner head; and an inner combustion ring, which is located at the center of the burner head and forms a first gas supply chamber with the burner head.

[0015] Furthermore, it also includes: a third impeller located in the premixing chamber, the third impeller being able to rotate in response to the pressure component to turbulently mix the combined gas and air; a top cover located at the air inlet of the first air supply chamber, the top cover being able to move downward in response to the pressure component to control the opening size of the first air supply chamber; and a sealing ring located at the air inlet of the second air supply chamber, the sealing ring being able to move downward in response to the pressure component to control the opening size of the second air supply chamber.

[0016] The present invention has the following beneficial effects:

[0017] (1) The gas burner for the high thermal efficiency of the frying furnace uses the gas release pressure itself as the driving source and the driving pressure component as the driving carrier to generate the state of driving the annular valve plate to open the air passage. When the gas release pressure flow is small, the air passage opens a smaller channel simultaneously, and when the gas release pressure flow is large, the air passage opens a larger channel simultaneously, so as to maintain the dynamic synchronicity of the gas jet driving the air entrainment, so that the gas and air maintain a dynamic mixing balance, improve the gas combustion completeness, and avoid the situation of incomplete gas combustion producing nitrogen oxides.

[0018] (2) The gas burner for the high thermal efficiency of the frying oven drives the impeller in the gas chamber to rotate by the pressure released by the gas itself, so that the gas can be ejected in a spiral state. Furthermore, by using the blower to drive the impeller in the air chamber to rotate, the air can be evenly distributed in a spiral state. This allows the gas jet to entrain the dynamically surrounding air, improving the uniformity of the gas-air mixture and improving the mixing ratio by means of its spiral state.

[0019] (3) The gas burner for the high thermal efficiency of the frying furnace can drive the impeller in the premixing chamber to rotate by the pressure of the gas itself, so that the mixed gas and air are turbulently mixed again, so that the gas and air are fully mixed and supplied to the burner head.

[0020] (4) The gas burner for the high thermal efficiency of the wok can open the top cover and the sealing ring by driving the pressure component through the release pressure of the gas itself. When the release pressure flow of the gas itself is small, the top cover is controlled to move away from the corresponding gas supply chamber to provide the gas supply required for the combustion of the inner combustion ring. When the release pressure flow of the gas itself gradually increases, the sealing ring is controlled to move away from the corresponding gas supply chamber to provide the gas supply required for the combustion of the outer combustion ring, so that the size of the burner head combustion is synchronized with the size of the gas supply.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0058] The following describes a gas burner for a wok with high thermal efficiency proposed in this invention, with reference to Figures 1-33.

[0059] Example 1: As shown in Figures 1-4, 11, and 17, this high-efficiency gas burner for a wok includes a burner head 1 and a furnace sleeve 2 located below the burner head 1. A gas channel is formed between the furnace sleeve 2 and the burner head 1, and a premixing chamber is formed at the top of the gas channel. A gas chamber 13 is provided at the bottom of the gas channel, and a gas passage 21 is provided circumferentially (as shown in Figure 11). An air chamber 12 is provided above the gas chamber 13, and an air passage 24 is provided circumferentially (as shown in Figure 17). This allows the gas in the gas chamber 13 to be ejected through the gas passage 21. During the ejection process, the gas is drawn into the air passage 24, causing the gas and air to flow together into the premixing chamber.

[0060] Furthermore, an annular valve plate is provided above the gas passage 21. The annular valve plate can close the air passage 24 in a normally closed state. At the same time, a pressure component is provided below the annular valve plate. The pressure component can generate a drive in response to the release pressure of the gas itself, and control the opening size of the annular valve plate to the air passage 24, so that the gas and air are mixed quantitatively in a spiral state. After mixing, it is delivered to the premixing chamber for further mixing. After being fully mixed, the gas is selectively delivered to the inner and outer rings of the burner head 1 in response to the pressure and flow rate of the gas itself, so that the combustion size of the burner head 1 is synchronized with the gas supply size.

[0061] As shown in Figures 8-16, to open the air passage 24 via the annular valve plate, the pressure assembly includes a piston 16 located inside the gas chamber 13. A second impeller 15 is rotatably mounted on the piston 16. Simultaneously, a gas valve pipe 4 is provided on the gas chamber 13 (the gas valve pipe 4 is tangentially aligned with the blades of the second impeller 15, so that the gas delivered by the gas valve pipe 4, under its own pressure impact, can drive the second impeller 15 to rotate). First guide rings 20 are interlaced on the blades of the second impeller 15, so that the gap between the first guide rings 20 and the second impeller 15 forms a gas passage 21 (the bottom inlet of the gas passage 21 has a narrow opening structure, ensuring that the gas pressure flow rate is always greater than the narrow opening output flow rate; the top of the gas passage 21 has a spiral structure, allowing the gas to flow along the spiral structure during output, tending towards a spiral state, and utilizing the rotation of the second impeller 15 to maintain a spiral jet state when the gas jet exits). The first guide rings 20 are fixedly connected to the first annular valve plate 25. When using a switch... When the valve of the gas valve pipe 4 is controlled, the gas is delivered to the gas chamber 13 under pressure. Since the gas pressure and flow rate are always greater than the output flow rate of the gas passage 21, the gas is slowly accumulated in the gas chamber 13 while being jetted out, applying pressure to the piston 16 and pushing the piston 16 downward. As the valve of the gas valve pipe 4 gradually increases in opening and closing, the gas pressure and flow rate increase, and the output flow rate of the gas through the gas passage 21 increases synchronously. At this time, the pressure acting on the piston 16 also increases synchronously, pushing the piston 16 further downward. During the downward movement of the piston 16, the first annular valve plate 25 is continuously moved away from the air passage 24, so that the air passage 24 maintains a larger opening state as the gas pressure and flow rate increase. This allows the jetted gas to entrain more air from the air passage 24, so that the air passage 24 can maintain a dynamic opening size according to the size of the gas jet, achieving a mixing balance between gas and air under dynamic changes and improving the completeness of gas combustion.

[0062] Furthermore, the pressure assembly also includes a second magnetic ring 23 located below the piston 16, and a first magnetic ring 22 located below the second magnetic ring 23 (as shown in Figures 15-16). The first magnetic ring 22 and the second magnetic ring 23 repel each other magnetically, forming a deformation space to allow the piston 16 to move downward under force. The magnetic repulsion between the first magnetic ring 22 and the second magnetic ring 23 provides magnetic support for the piston 16, so that the piston 16 gradually overcomes the magnetic force and moves downward when subjected to changes in the gas pressure (the gas inlet pressure of burners used in restaurants, hotels and other places is generally between 3000 and 5000 Pa. The force conversion is intuitively equivalent to a 3 to 5 kg object pressing on an area the size of a palm. The pressure area of ​​the piston 16 located in the gas chamber 13 is similar to the size of a palm. Therefore, the piston 16 can overcome the magnetic force between the two sets of magnetic rings and move downward under force).

[0063] It should be noted that a first fixed ring 18 and a first movable ring 17 are respectively provided on the outer rings of the first magnetic ring 22 and the second magnetic ring 23 to limit and fix the two sets of magnetic rings. Furthermore, the first fixed ring 18 and the first movable ring 17 also maintain relative sliding to provide limiting guidance when the piston 16 moves under force.

[0064] As shown in Figures 8-9 and 17-20, to achieve the mixing of gas and air, a first impeller 14 is rotatably installed inside the air chamber 12, and an air inlet pipe 3 is provided on one side of the air chamber 12 (the air inlet pipe 3 is tangentially aligned with the first impeller 14, so that when external equipment such as blowers deliver air into the air chamber 12 through the air inlet pipe 3, the wind force generated by the air can drive the first impeller 14 to rotate). The blades of the first impeller 14 form an air passage 24 for air circulation, so that when the gas is spirally ejected from the gas passage 21 in response to the rotation of the second impeller 15, the air can synchronously respond to the rotation of the first impeller 14 and spirally rotate along the air passage 24. Then, under the entrainment of the gas jet, the gas and air are mixed in a spiral state to improve the mixing efficiency (as shown in Figures 18-20).

[0065] It should be noted that the pressure assembly also includes a first drive shaft 11 located in the middle of the second impeller 15. The first drive shaft 11 extends into the premixing chamber and can rotate synchronously in response to the rotation of the second impeller 15. The first drive shaft 11 is connected to a third impeller 19 located in the premixing chamber, so that when the gas and air are combined and delivered to the premixing chamber, the third impeller 19, driven by the first drive shaft 11, further turbulently mixes the gas and air to ensure that the two are fully combined (as shown in Figures 8-9).

[0066] As shown in Figures 3-7, to achieve synchronous emission of the mixed fuel gas and air, an outer combustion ring 5 is provided along the edge of the burner head 1, forming a second air supply chamber 8 between the outer ring and the burner head 1. An inner combustion ring 6 is provided at the center of the burner head 1, forming a first air supply chamber 7 between the inner ring and the inner ring. Simultaneously, a top cover 9 is provided on the inner ring of the third impeller 19, located at the air inlet of the first air supply chamber 7. A sealing ring 10 is provided on the outer ring of the third impeller 19, located at the air inlet of the second air supply chamber 8. When the third impeller 19 is driven by the rotation of the first drive shaft 11, it can also move downward in response to the downward movement of the first drive shaft 11, causing the combination of the top cover 9 and the sealing ring 10 to move downward synchronously. When the gas delivery pressure and flow rate are small, the piston 16 moves downward a small amount, which in turn causes the first drive shaft 11 to move downward slightly, removing the top cover 9 from the first gas supply chamber 7. This allows the mixed gas and air to be delivered to the inner combustion ring 6 through the first gas supply chamber 7, providing the gas required for small-fire combustion (at this time, the upper end of the sealing ring 10 can continuously seal the second gas supply chamber 8). Furthermore, when the gas delivery pressure and flow rate are large, the piston 16 moves downward more, and the first drive shaft 11 moves downward more, so that while the top cover 9 continues to move away from the first gas supply chamber 7, the sealing ring 10 can move away from the second gas supply chamber 8 synchronously. This allows the mixed gas and air to be distributed along the second gas supply chamber 8 to the outer combustion ring 5, providing the gas required for large-fire combustion, so that the size of the combustion at the burner head 1 is synchronized with the size of the gas supply.

[0067] During use (operation), the valve size of the gas valve pipe 4 is controlled by a switch, allowing gas to be delivered into the gas chamber 13 under pressure. When the gas is delivered into the gas chamber 13, because the gas pressure and flow rate are always greater than the output flow rate of the gas passage 21, the gas is jetted out while simultaneously accumulating slowly within the gas chamber 13. This exerts pressure on the piston 16, pushing it downwards and generating a driving force that moves the first annular valve plate 25 downwards. This causes the first annular valve plate 25 to move away from the air passage 24, thus opening the air passage 24. When the gas is turned on, the gas supply can drive the second impeller 15 to rotate, causing the gas to move in a spiral state. At this time, external blowers and other equipment simultaneously deliver air to the air chamber 12 through the air inlet pipe 3. The air force generated by the air can drive the first impeller 14 to rotate, so that when the gas is spirally ejected from the gas passage 21 in response to the rotation of the second impeller 15, the air can synchronously respond to the rotation of the first impeller 14 and spirally rotate along the air passage 24. Then, under the entrainment of the gas jet, the gas and air are mixed in a spiral state.

[0068] While the second impeller 15 rotates and moves downward, the first drive shaft 11 rotates and moves downward synchronously, which drives the third impeller 19 to rotate and the top cover 9 and sealing ring 10 to move downward synchronously. The rotation of the third impeller 19 mixes the gas and air again. The top cover 9 and sealing ring 10 open sequentially to selectively deliver the mixed gas to the first gas supply chamber 7 and the second gas supply chamber 8, so that the size of the combustion is synchronized with the size of the gas supply and the size of the combustion flame is controlled synchronously.

[0069] Example 2, as shown in Figures 21-33, differs from Example 1 in that its pressure assembly includes a fourth impeller 42 rotatably mounted inside the gas chamber 13. The fourth impeller 42 rotates in response to the impact of the gas jet, and a second guide ring 43 is provided on the blades of the fourth impeller 42, forming a gas passage 21 between the second guide ring 43 and the fourth impeller 42. After the gas drives the fourth impeller 42 to rotate, it spirally jets out along the gas passage 21. At the same time, a second drive shaft 26 is slidably engaged in the middle of the fourth impeller 42. The second drive shaft 26 can rotate synchronously in response to the rotation of the fourth impeller 42 and generate an axial movement driving force, which drives the second annular valve plate 39 mounted on the second drive shaft 26 to move downward. By utilizing the change of the pressure and flow rate of the gas itself, the second annular valve plate 39 controls the synchronous opening of the air passage 24, so that the gas spirally jetted out is drawn in with the air in the spiral flow state for quantitative mixing.

[0070] It should be noted that, as shown in Figures 32 and 33, the inner ring of the second annular valve plate 39 is provided with a support ring 38, and the support ring 38 is rotatably connected to the first limiting ring 31 provided on the second drive shaft 26, so that the second annular valve plate 39 is only subjected to the downward pressure of the second drive shaft 26 and does not rotate synchronously with the second drive shaft 26, thereby reducing the overall self-weight and rotational load drive of the second drive shaft 26. Furthermore, the outer ring of the second annular valve plate 39 is provided with a limiting slip 40, and the inner ring of the first impeller 14 is provided with a limiting groove 41. By utilizing the sliding combination of the limiting slip 40 and the limiting groove 41, the second annular valve plate 39 is slidably installed on the first impeller 14, providing a guide limit for the downward movement of the second annular valve plate 39.

[0071] In addition, a first long gear 32 is provided on the second drive shaft 26, and a first internal gear ring 35 is provided on the fourth impeller 42. The first long gear 32 can slide and mesh along the first internal gear ring 35 to realize the rotation and movement of the second drive shaft 26 along the fourth impeller 42.

[0072] As a further embodiment of this invention, as shown in Figures 27-31, to achieve synchronous downward movement during rotation of the second drive shaft 26, the pressure assembly further includes a power generation coil 30 located at the bottom of the second drive shaft 26, and an electromagnet 36 located above the power generation coil 30. The electromagnet 36 is positioned opposite to the armature ring 37 rotatably mounted on the second drive shaft 26, so that when the second drive shaft 26 rotates, the power generation coil 30 generates electricity in response to the rotation of the second drive shaft 26. When the electromagnet 36 is energized, a magnetic attraction force is generated, causing the armature ring 37 to move closer to the electromagnet 36. During this movement, a driving force is generated to move the second drive shaft 26. The driving force of the downward movement of the drive shaft 26 then drives the second annular valve plate 39 downward by the downward movement of the second drive shaft 26, opening the air passage 24. As the pressure and flow rate of the gas changes, the rotational push of the fourth impeller 42 also changes, causing the power acting on the generator coil 30 when the second drive shaft 26 rotates to change, which in turn changes the magnetic attraction force of the control electromagnet 36, dynamically driving the downward movement of the second drive shaft 26. This allows the second annular valve plate 39 to control the opening size of the air passage 24 according to the pressure and flow rate of the gas, so that the gas and air are kept in a metered mixture.

[0073] It should be noted that, as shown in Figures 27-29, the generating coil 30 consists of a housing 301, a turntable 302, a magnet ring 303, a second internal gear ring 304, and an induction coil 305. The induction coil 305 is located inside the housing 301, and the magnet ring 303 is located inside the turntable 302. The second internal gear ring 304 is located in the middle of the turntable 302 and maintains a sliding engagement with the second long gear 34 located on the second drive shaft 26 (the sliding engagement between the second long gear 34 and the second internal gear ring 304 allows the second drive shaft 26 to slide and rotate on the turntable 302). When the second drive shaft 26 rotates, it drives the turntable 302 to rotate, causing the magnet ring 303 to rotate relative to the induction coil 305. The magnetic field of the magnet ring 303 cuts the induction coil 305 as the turntable 302 rotates, generating an alternating induced electromotive force. The induced electromotive force forms an alternating current through the induction coil 305 and is output to the electromagnet 36, causing the electromagnet 36 to generate an electromagnetic attraction force.

[0074] Furthermore, as shown in Figures 30 and 31, a combination of a second movable ring 27 and a second fixed ring 28 is provided below the gas chamber 13, and a strain spring 29 is provided between the second movable ring 27 and the second fixed ring 28. An electromagnet 36 is provided on the second fixed ring 28, and an armature ring 37 is provided on the second movable ring 27 and is rotatably connected to the second limiting ring 33 provided on the second drive shaft 26. This allows the armature ring 37 to only apply downward pressure to the second drive shaft 26 and not to rotate synchronously with the second drive shaft 26, thereby reducing the overall self-weight and rotational load driving of the second drive shaft 26. At the same time, the combination of the second movable ring 27 and the second fixed ring 28 can guide and limit the movement of the armature ring 37 by magnetic force. The strain spring 29 provided between the second movable ring 27 and the second fixed ring 28 can provide self-resetting after the armature ring 37 moves, so that when the gas supply stops, it pushes the second drive shaft 26 to reset.

[0075] Furthermore, the second drive shaft 26 extends into the premixing chamber and is connected to the combination of the third impeller 19, the top cover 9, and the sealing ring 10. The second drive shaft 26 responds to the rotation of the fourth impeller 42 to generate a driving force that drives the third impeller 19 to rotate, thus fully mixing the gas and air. In response to the downward movement of the magnetic attraction, the second drive shaft 26 generates a driving force that drives the top cover 9 and the sealing ring 10 to open, thus delivering the mixed gas and air into the burner head 1 for combustion.

[0076] Unlike Embodiment 1, in use (operation), when the gas is delivered into the gas chamber 13, it drives the fourth impeller 42 to rotate. The rotation of the fourth impeller 42 drives the second drive shaft 26 to rotate. During the rotation of the second drive shaft 26, the generator coil 30 generates electricity, which energizes the electromagnet 36. This generates a magnetic attraction force that moves the armature ring 37 toward the electromagnet 36. At the same time, this movement generates a driving force that drives the second drive shaft 26 to move downward. Then, the downward movement of the second drive shaft 26 drives the second annular valve plate 39 to move downward, opening the air passage 24 so that the gas and air are kept in a metered spiral mixture.

[0077] Furthermore, the rotation and downward movement of the second drive shaft 26 simultaneously acts on the third impeller 19, the top cover 9, and the sealing ring 10, thereby achieving the remixing of gas and air, as well as the synchronous change of the gas supply and combustion intensity.
