Description

Technical Field

[0001] This invention relates to the field of burner technology, and in particular to a combustion furnace with separate heat control. Background Technology

[0002] Current combustion furnaces typically only allow for unified control of the flame output in the entire area during operation. When the combustion furnace needs to heat a pot with two chambers, the required heat output differs because the liquids in the two chambers have different boiling points. In this case, unified control of the flame output in the entire area is insufficient to meet the needs of both chambers simultaneously. Therefore, there is an urgent need for a combustion furnace that can control the heat output in different zones. Summary of the Invention

[0003] The purpose of this invention is to provide a fire-controlled combustion furnace to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this invention is:

[0005] A fire-controlled combustion furnace includes: a burner internally divided into a first mixing chamber and a second mixing chamber; a first flame outlet communicating with the first mixing chamber is provided on the top side of the burner, and multiple first flame outlets are arranged around the center of the burner; a second flame outlet communicating with the second mixing chamber is provided on the top side of the burner, and multiple second flame outlets are arranged around the center of the burner; and a gas distribution assembly capable of supplying gas to the first mixing chamber and / or the second mixing chamber.

[0006] This technical solution has at least the following beneficial effects: Multiple first flame outlets on the top side of the burner form a first flame outlet zone, and multiple second flame outlets form a second flame outlet zone. During use, the operating states of the first and second flame outlet zones can be controlled separately according to different usage needs. Specifically, the gas distribution component supplies gas only to the first mixing chamber, at which point the gas in the first mixing chamber is dispersed outward through multiple first flame outlets and burns only in the area covered by the multiple first flame outlets; or the gas distribution component supplies gas only to the second mixing chamber, at which point the gas in the second mixing chamber is dispersed outward through multiple second flame outlets and burns only in the area covered by the multiple second flame outlets; or the gas distribution component supplies gas to both the first and second mixing chambers simultaneously, at which point the multiple first and second flame outlets simultaneously emit gas and burn. This forms independently controllable flame outlet zones, allowing for separate heating of different parts of the cookware, thereby adapting to different heat requirements and improving usage flexibility and thermal efficiency.

[0007] As a further improvement to the above technical solution, the gas distribution assembly includes a gas distribution valve, an intake pipe, a first gas distribution pipe, and a second gas distribution pipe. The gas distribution valve includes a valve seat and a valve core rotatably connected to the valve seat. The valve seat has a first channel and a first flow channel perpendicular to and connected to the first channel. One end of the first channel is connected to the first mixing chamber through the first gas distribution pipe, and the other end of the first channel is connected to the second mixing chamber through the second gas distribution pipe. The intake pipe is connected to the first flow channel. The valve core is located at the junction of the first channel and the first flow channel. The valve core has a second channel corresponding to the position of the first channel, and the valve core has a second flow channel corresponding to the position of the first flow channel.

[0008] As a further improvement to the above technical solution, a first ejector tube is formed on the outside of the burner corresponding to the position of the first mixing chamber, and the first gas distribution pipe is connected to the end of the first ejector tube away from the burner. A second ejector tube is formed on the outside of the burner corresponding to the position of the second mixing chamber, and the second gas distribution pipe is connected to the end of the second ejector tube away from the burner.

[0009] As a further improvement to the above technical solution, the first ejector tube and the second ejector tube are located on both sides of the burner.

[0010] As a further improvement to the above technical solution, a partition plate is provided inside the burner, which divides the interior of the burner into a first mixing chamber and a second mixing chamber. The partition plate is located on both sides of the center of the burner and forms a first arc-shaped portion and a second arc-shaped portion, respectively. The opening directions of the first arc-shaped portion and the second arc-shaped portion are opposite. The gas outlet direction of the first ejector tube is tangent to the side of the first arc-shaped portion away from the center of the burner, and the gas outlet direction of the second ejector tube is tangent to the side of the second arc-shaped portion away from the center of the burner.

[0011] As a further improvement to the above technical solution, a first guide vane is provided in the first mixing chamber. One side of the first guide vane is directly opposite the first ejector tube, and the other side of the first guide vane extends to the middle of the first mixing chamber and is spirally arranged.

[0013] As a further improvement to the above technical solution, a first mixing cylinder is provided inside the first ejector tube, which enables a rotating airflow to be formed inside the first ejector tube.

[0014] As a further improvement to the above technical solution, a second mixing cylinder is provided inside the second ejector tube, which can cause a rotating airflow to be formed inside the second ejector tube.

[0015] As a further improvement to the above technical solution, a control valve is provided on the air intake pipe.

[0029] Reference Figure 1 and Figure 2A heat-controlled combustion furnace includes a burner 100 and a gas distribution assembly. The burner 100 is internally divided into a first mixing chamber and a second mixing chamber. A first flame outlet 110 communicating with the first mixing chamber is provided on the top side of the burner 100. Multiple first flame outlets 110 are arranged around the center of the burner 100. A second flame outlet 120 communicating with the second mixing chamber is provided on the top side of the burner 100. Multiple second flame outlets 120 are arranged around the center of the burner 100. In practical applications, the multiple first flame outlets 110 are arranged in an arc shape on the top side of the burner 100, and similarly, the multiple second flame outlets 120 are arranged in an arc shape on the top side of the burner 100. The gas distribution assembly can supply gas to the first mixing chamber, or to the second mixing chamber, or simultaneously to both the first and second mixing chambers.

[0030] As described above, the multiple first flame outlets 110 on the top side of the burner 100 form a first flame outlet zone, and the multiple second flame outlets 120 form a second flame outlet zone. During use, the operating states of the first and second flame outlet zones can be controlled separately according to different usage needs. Specifically, the gas distribution component supplies gas only to the first mixing chamber, at which point the gas in the first mixing chamber is dispersed outward through the multiple first flame outlets 110 and burns only in the area covered by the multiple first flame outlets 110; or the gas distribution component supplies gas only to the second mixing chamber, at which point the gas in the second mixing chamber is dispersed outward through the multiple second flame outlets 120 and burns only in the area covered by the multiple second flame outlets 120; or the gas distribution component supplies gas to both the first and second mixing chambers simultaneously, at which point the multiple first flame outlets 110 and the multiple second flame outlets 120 simultaneously emit gas and burn. This forms independently controllable flame outlet zones, allowing for separate heating of different parts of the cookware, thereby adapting to different heat requirements and improving usage flexibility and thermal efficiency.

[0031] As a specific structural form of the valve train, such as Figure 3 , Figure 4As shown, in this embodiment, the gas distribution assembly includes a gas distribution valve 210, an intake pipe 220, a first gas distribution pipe 230, and a second gas distribution pipe 240. The gas distribution valve 210 includes a valve seat 211 and a valve core 212 rotatably connected to the valve seat 211. The valve seat 211 has a first channel 213 and a first flow channel 214 perpendicular to and connected to the first channel 213. One end of the first channel 213 is connected to the first mixing chamber through the first gas distribution pipe 230, and the other end of the first channel 213 is connected to the second mixing chamber through the second gas distribution pipe 240. The intake pipe 220 is connected to the first flow channel 214. The valve core 212 is located at the junction of the first channel 213 and the first flow channel 214. The valve core 212 has a second channel 215 corresponding to the position of the first channel 213, and a second flow channel 216 corresponding to the position of the first flow channel 214.

[0032] In this embodiment, when the second channel 215 is directly opposite the first channel 213 and the second flow channel 216 is directly opposite the first flow channel 214, when the air inlet pipe 220 is open, the airflow enters the second flow channel 216 from the first flow channel 214, is divided into two ends of the second channel 215 in the valve core 212, and flows into the two ends of the first channel 213 respectively. Finally, it enters the first mixing chamber and the second mixing chamber from the first air distribution pipe 230 and the second air distribution pipe 240 respectively. This is the state of simultaneously supplying air to the first mixing chamber and the second mixing chamber. When only the first mixing chamber needs to be supplied with air, rotate valve core 212 so that the second flow channel 216 is directly opposite the first branch pipe. At this time, one end of the second channel 215 is directly opposite the first flow channel 214, while the other end is directly opposite the inner wall of valve seat 211 and closed. Air inlet pipe 220 is open, and the airflow flows sequentially through the first flow channel 214, the second channel 215, the second flow channel 216, and the first channel 213 before entering the first branch pipe. When only the second mixing chamber needs to be supplied with air, rotate valve core 212 so that the first flow channel 214 is directly opposite the second branch pipe. In this configuration, one end of the second channel 215 is aligned with the second flow channel 216, while the other end is closed against the inner wall of the valve seat 211. The air intake pipe 220 is open, and the airflow sequentially flows through the first flow channel 214, the second channel 215, the second flow channel 216, and the first channel 213 before entering the second diverter pipe. In practical applications, the adjusting valve core 212 can be rotated to change the communication area between the first flow channel 214 and the second channel 215, thereby changing the air intake volume and controlling the flame size. For example, rotating the adjusting valve core 212... When the connection area between the first flow channel 214 and the second channel 215 is reduced, the air intake can be reduced, thereby reducing the flame output. Conversely, rotating the adjusting valve core 212 increases the connection area between the first flow channel 214 and the second channel 215, thereby increasing the air intake and increasing the flame output. When it is necessary to shut down the entire burner 100, rotating the valve core 212 makes the second flow channel 216 face the inner wall of the valve seat 211 and the first flow channel 214 face the outer side of the valve core 212, preventing air from passing into the valve core 212 and thus achieving flame shutdown.

[0033] When the intake pipe 220 only supplies fuel gas, the burner 100 also needs to be equipped with a structure that allows air to enter. Specifically, a first ejector pipe 130 is formed on the outside of the burner 100 corresponding to the position of the first mixing chamber. The first gas distribution pipe 230 is connected to the end of the first ejector pipe 130 away from the burner 100. Naturally, a first air inlet for outside air is provided at the end of the first ejector pipe 130 away from the burner 100. A second ejector pipe 140 is formed on the outside of the burner 100 corresponding to the position of the second mixing chamber. The second gas distribution pipe 240 is connected to the end of the second ejector pipe 140 away from the burner 100. Similarly, a second air inlet for outside air is provided at the end of the second ejector pipe 140 away from the burner 100. When gas is input into the intake pipe 220 and enters the first gas distribution pipe 230, the gas first enters the first ejector pipe 130 and mixes with the air entering through the first ejector pipe 130, and then is injected into the first mixing chamber for further mixing. This improves the mixing effect of gas and air. Similarly, when gas is input into the intake pipe 220 and enters the second gas distribution pipe 240, the gas first enters the second ejector pipe 140 and mixes with the air entering through the second ejector pipe 140, and then is injected into the second mixing chamber for further mixing.

[0034] To reduce mutual interference between the first ejector tube 130 and the second ejector tube 140 when air is introduced, in this embodiment, the first ejector tube 130 and the second ejector tube 140 are respectively located on both sides of the burner 100. During use, air is drawn into the burner 100 from both sides of the burner 100 via the first ejector tube 130 and the second ejector tube 140, which helps to ensure the amount of air supplied to the first ejector tube 130 and the second ejector tube 140.

[0035] The burner 100 has a structure that divides the internal space, which can be a flat plate. To facilitate the intake of air into the burner 100 via the first ejector tube 130 and improve intake efficiency, such as... Figure 5As shown, in this embodiment, a partition plate 150 is provided inside the burner 100. The partition plate 150 divides the interior of the burner 100 into a first mixing chamber and a second mixing chamber. The partition plate 150 forms a first arc-shaped portion and a second arc-shaped portion on both sides of the center of the burner 100. The opening directions of the first arc-shaped portion and the second arc-shaped portion are opposite. The gas outlet direction of the first ejector tube 130 is tangent to the side of the first arc-shaped portion away from the center of the burner 100, and the gas outlet direction of the second ejector tube 140 is tangent to the side of the second arc-shaped portion away from the center of the burner 100. When the first ejector tube 130 supplies mixed gas to the first mixing chamber and the second ejector tube 140 supplies mixed gas to the second mixing chamber, the gas outlet direction of the first ejector tube 130 is tangent to the side of the first arc-shaped portion away from the center of the burner 100, and the gas outlet direction of the second ejector tube 140 is tangent to the side of the second arc-shaped portion away from the center of the burner 100. The mixed gas can flow along the first arc-shaped portion and the second arc-shaped portion, which is conducive to the smooth entry of the mixed gas into the first mixing chamber and the second mixing chamber, and the formation of a rotating airflow in the first mixing chamber and the second mixing chamber, thereby enhancing the effect of further diffusion and mixing of the mixed gas in the first mixing chamber and the second mixing chamber.

[0036] To further improve the diffusion and mixing effect of the gas mixture in the first mixing chamber, in this embodiment, a first guide vane 160 is provided in the first mixing chamber. One side of the first guide vane 160 faces the first ejector tube 130, and the other side of the first guide vane 160 extends to the middle of the first mixing chamber and is spirally arranged. A guide gap is formed between the first guide vane 160 and the first arc-shaped portion. When the gas mixture enters the first mixing chamber, part of the gas mixture enters the guide gap and then flows to the position of the first mixing chamber near the second arc-shaped portion, while part of the gas mixture flows to the middle of the first mixing chamber under the guidance of the first guide vane 160. As the spiral first guide vane 160 rotates and rises, it mixes further. When it flows upward out of the first guide vane 160 and blows towards the inner top side of the first mixing chamber, the gas mixture is dispersed and flows to the surroundings. This facilitates further mixing of the gas mixture in the first mixing chamber and allows it to be uniformly and quickly guided to the multiple first flame outlets 110.

[0037] To further improve the diffusion and mixing effect of the gas mixture in the first mixing chamber, in this embodiment, a second guide vane 170 is provided in the second mixing chamber. One side of the second guide vane 170 faces the second ejector tube 140, and the other side of the second guide vane 170 extends to the middle of the second mixing chamber and is spirally arranged. A guide gap is formed between the second guide vane 170 and the second arc-shaped portion. When the gas mixture enters the second mixing chamber, part of the gas mixture enters the guide gap and then flows to the position of the second mixing chamber near the first arc-shaped portion, while part of the gas mixture flows to the middle of the second mixing chamber under the guidance of the second guide vane 170. As the spiral second guide vane 170 rotates and rises, it mixes further. When it flows upward out of the second guide vane 170 and blows towards the inner top side of the second mixing chamber, the gas mixture is dispersed and flows to the surrounding area. This facilitates further mixing of the gas mixture in the second mixing chamber and allows it to be uniformly and quickly guided to the multiple second flame outlets 120.

[0038] To improve the mixing effect of air and fuel gas within the first injector 130, such as Figure 6 As shown, in this embodiment, a first mixing cylinder 131 is provided inside the first ejector tube 130. The first mixing cylinder 131 can cause a rotating airflow to form inside the first ejector tube 130. The rotating airflow can promote the premixing of air and combustion within the first ejector tube 130, thereby improving the fuel utilization rate and thermal efficiency at the final gas output.

[0039] There are several ways to create a rotating airflow within the first ejector tube 130 using the first mixing cylinder 131. For example, multiple spirally extending grooves can be provided directly on the inner wall of the first ejector tube 130. When the gas and air pass through the grooves, they will be guided to rotate and mix. In order to further improve the mixing efficiency of air and gas within the first ejector tube 130, in this embodiment, the first ejector tube 130 includes a first straight section 132 and a first narrowing section 133 that are connected to each other. A first connecting rib 134 is connected between the outer side of the first mixing cylinder 131 and the inner side of the first straight section 132. A first swirling gap is formed between the first mixing cylinder 131 and the first straight section 132. Multiple first guide grooves 135 are provided on the outer side of the first mixing cylinder 131, and the multiple first guide grooves 135 extend spirally on the outer side of the first mixing cylinder 131. When air and fuel gas enter the first straight section 132, part of the mixture enters the first mixing cylinder 131, and part of the mixture enters the first swirling gap formed between the outer side of the first mixing cylinder 131 and the inner side of the first straight section 132. This part of the mixture, guided by multiple first guide grooves 135, forms an airflow that rotates around the outer side of the first mixing cylinder 131. By using the first mixing cylinder 131 to spatially separate the mixture, a laminar flow with a stronger velocity can be formed on the outer side of the first mixing cylinder 131, which enhances the disturbance and mixing of the airflow located at the outer position. When flowing out of the first swirling gap, it can also drive the mixture from the first mixing cylinder 131 to rotate and mix. When reaching the first narrowing section 133, the swirling mixture can be further compressed into the axis of the first narrowing section 133, which enhances the disturbance and mixing of the mixture in the middle position. Finally, it flows out from the first narrowing section 133, which can form a higher speed and a better mixing effect airflow.

[0040] To improve the mixing effect of air and fuel gas within the second ejector tube 140, in this embodiment, a second mixing cylinder is provided inside the second ejector tube 140. The second mixing cylinder enables the formation of a rotating airflow within the second ejector tube 140. The rotating airflow can promote the premixing of air and combustion within the second ejector tube 140, thereby improving the fuel gas utilization rate and thermal efficiency at the final exhaust gas.

[0041] Similarly, there are multiple ways to create a rotating airflow inside the second ejector tube 140 using the second mixing cylinder. For example, multiple spirally extending grooves can be provided directly on the inner wall of the second ejector tube 140. When the gas and air pass through the grooves, they will be guided to rotate and mix. In order to further improve the efficiency of mixing air and gas inside the second ejector tube 140, in this embodiment, the second ejector tube 140 includes a second straight section and a second narrowing section that are connected to each other. A second connecting rib is connected between the outer side of the second mixing cylinder and the inner side of the second straight section. A second swirling gap is formed between the second mixing cylinder and the second straight section. Multiple second guide grooves are provided on the outer side of the second mixing cylinder, and the multiple second guide grooves extend spirally on the outer side of the second mixing cylinder. When air and fuel gas enter the second straight section, part of the mixture enters the second mixing cylinder, while the rest enters the second swirling gap formed by the outer side of the second mixing cylinder and the inner side of the second straight section. This part of the mixture, guided by multiple second guide channels, forms an airflow that rotates around the outer side of the second mixing cylinder. By using the second mixing cylinder to spatially separate the mixture, a laminar flow with a stronger velocity can be formed on the outer side of the second mixing cylinder, enhancing the disturbance and mixing of the airflow located at the outer position. When flowing out of the second swirling gap, it can also drive the mixture from the second mixing cylinder to rotate and mix. When reaching the second narrowing section, the swirling mixture can be further compressed into the axis of the second narrowing section, enhancing the disturbance and mixing of the mixture in the middle position. Finally, it flows out from the second narrowing section, forming a higher speed and better mixing airflow.

[0042] In the above embodiment, the air supply to the multiple first flare holes 110 and multiple second flare holes 120 can be stopped by rotating the valve core 212. To improve safety, a control valve 250 is provided on the air intake pipe 220. The control valve 250 can directly close and open the air intake pipe 220, improving the overall control flexibility and safety.

[0043] In practical applications, the burner 100 is also equipped with a flame sensing needle. When the burner 100 is working, the flame can heat the sensing end of the flame sensing needle. When there is a flame, a signal to open the control valve 250 is output, and when the flame is extinguished, a signal to close the control valve 250 is output.

[0044] A dry-burning prevention sensor and a cookware weight sensor are also provided on the top side of the burner 100. When the dry-burning prevention sensor detects high dry-burning temperature, it outputs a signal to close the control valve 250. When the cookware weight sensor detects that there is no cookware within a certain period of time, it outputs a signal to close the control valve 250.
