Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to an anti-dry-burning burner and stove. Background Technology

[0002] A current problem with anti-dry-burning cooktops is that the temperature control probe's detection end is installed too close to the inner ring burner cap. To ensure effective contact between the detection end and the bottom of the pot after it's placed, the detection end must extend beyond the plane of the inner ring burner cap. However, this arrangement causes the flame and high-temperature smoke from the inner ring burner holes to continuously act on the detection end during combustion, resulting in a significant temperature rise even under non-dry-burning conditions. This thermal interference severely affects the probe's temperature measurement accuracy, leading to frequent misjudgments by the control system and triggering unnecessary protective shutdowns. This not only affects the continuity of the cooking process but also reduces the product's reliability. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects in the prior art where high-temperature flue gas interferes with the temperature control probe, resulting in low measurement accuracy and affecting the performance of the product, and to provide an anti-dry-burning burner and stove.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A dry-burning-proof burner includes a flame cap, a temperature control probe, and a base. The flame cap is disposed on the upper end of the base and together they form a mixing chamber for supplying gas to the flame orifice. The inner side of the base is provided with a cavity for accommodating the temperature control probe. A first chamber is provided at the top of the flame cap. In the height direction, the first chamber surrounds the temperature control probe and communicates with the mixing chamber. The communication position between the first chamber and the mixing chamber is higher than the highest point of the flame orifice of the flame cap.

[0006] In this design, by configuring the first chamber corresponding to the temperature control probe and connecting it to the mixing chamber formed by the burner cap and the upper sidewall of the base, with the connection point between the first chamber and the mixing chamber higher than the highest point of the burner cap's flame hole, the combustion gas can be collected and stably retained within the first chamber. This design fully utilizes the burner cap's own structure to form a physical heat insulation barrier, while further blocking the heat conduction path through the gas path connection between chambers, thus achieving multiple heat insulation protection effects. This design does not introduce any additional complex components, effectively improving the thermal stability and detection accuracy of the temperature control probe in high-temperature environments while maintaining structural simplicity, thereby enhancing the overall system's reliability and service life, achieving a balance between structural simplification and performance optimization.

[0007] Preferably, the flame cap includes a cap structure located at the top of the flame cap. The cap structure includes a first sidewall and a second sidewall. The first sidewall is located on the side of the cap structure closer to the temperature control probe, and the second sidewall is located on the side of the cap structure away from the temperature control probe. The first sidewall and the second sidewall extend downward along the top surface of the cap structure, and the first sidewall and the second sidewall together form the first chamber.

[0008] In this design, the cap structure at the top of the flame cap has a first sidewall and a second sidewall, which together form a first chamber. The top of the flame cap horizontally surrounds the temperature control probe, presenting a four-layer heat insulation structure. Along the direction closest to the temperature control probe, there are, in sequence, the second sidewall, the first chamber, the second sidewall, and the gap between the second sidewall and the temperature control probe. This four-layer heat insulation structure effectively isolates the flame and high-temperature smoke from the flame hole from the detection end of the temperature control probe. Compared with the single-layer heat insulation structure design in the prior art, the four-layer heat insulation structure provides a progressive heat control mode, which can effectively reduce heat interference, thereby improving the detection accuracy of the temperature control probe and enhancing the performance of the product.

[0009] Preferably, the flame cap includes a cap structure, the temperature control probe is located in the middle of the flame cap, the cap structure includes a first sidewall, the first sidewall is arranged around the temperature control probe, and the first sidewall extends from bottom to top in a direction away from the temperature control probe.

[0010] In this design, the first sidewall near the temperature control probe is designed with an outward expansion from bottom to top, creating a gradually widening opening at the top of the flame cap. This design effectively guides the high-temperature flue gas to diffuse naturally outward as it rises, preventing localized accumulation around the temperature control probe. This significantly reduces interference with the probe's detection accuracy, increases the airflow velocity in the upper part of the cavity containing the temperature control probe, facilitates the rapid removal of stagnant flue gas, further optimizes the stability of the detection environment, and effectively reduces the failure rate of the temperature control probe.

[0011] Preferably, the height of the top surface of the flame cap decreases in the direction away from the temperature control probe.

[0012] In this design, the burner cap top surface employs a continuous sloping configuration that gradually decreases towards the distal end from the near-temperature control detection side. This flow-guiding structure utilizes its surface slope to automatically and directionally guide the overflow liquid accumulated at the top to a preset collection area under the influence of gravity. This design not only effectively prevents overflow liquid from stagnating and spreading on the burner cap surface, but also fundamentally prevents problems such as burner hole blockage and decreased flame stability caused by liquid intrusion. Furthermore, this sloping layout further optimizes the hydrodynamic characteristics of the burner cap surface, ensuring uniform airflow distribution in the combustion zone while achieving efficient overflow liquid guidance, thereby improving the overall operational stability and reliability of the burner.

[0013] Preferably, the flame cap includes a cap structure, the cap structure includes a first sidewall and a second sidewall, the cap structure is located at the top of the flame cap, and the outer surfaces of the first sidewall and the second sidewall are smoothly connected to the top surface of the cap structure.

[0014] In this design, the outer surfaces of the first and second sidewalls are smoothly connected to the top surface of the cap structure, allowing the overflow or water vapor accumulated on the top of the inner sidewall of the flame cap to flow to the top surface of the cap structure under the influence of the rising airflow. The overflow then collects along the inclined top surface at the overflow collection point, thus guiding the overflow, preventing dirt accumulation, and extending the service life of the flame cap.

[0015] Preferably, the flame cap includes a cap structure, the cap structure includes a brim and a second sidewall, the brim extends radially away from the temperature control probe, and one end of the brim near the temperature control probe is connected to the second sidewall.

[0016] Preferably, the flame cap further includes a flame cap body; wherein, the top end of the flame cap body is connected to the cap structure, and the edge of the cap brim is further radially from the temperature control probe than the outermost part of the flame cap body is from the temperature control probe.

[0017] In this design, by making the edge of the cap further away from the temperature control probe in the radial direction than the outermost part of the burner body, an extended radial protection distance is created. This design ensures that overflowing liquid can fall directly and naturally after overflowing the cap, thereby effectively blocking its path to flow back to the surface of the burner body or further seep into the burner holes, significantly reducing the risk of contamination of the burner body and the probability of failure caused by liquid accumulation.

[0018] Preferably, the flame cap further includes a flame cap body, the inner wall of the flame cap body facing the base includes a first segment and a second segment, the first segment is located below the second segment, the first segment and the second segment are arranged sequentially in the vertical direction and connected to each other, the first segment extends from bottom to top along the direction close to the inner wall of the base, the second segment is disposed at the upper end of the inner wall of the flame cap body facing the base, and the second segment extends from bottom to top along the direction away from the inner wall of the base.

[0019] In this design, the inner wall of the burner cap facing the base is connected sequentially from bottom to top with a first section and a second section. The first section extends from bottom to top along the inner wall close to the base, and the second section extends from bottom to top along the inner wall away from the base. At the bottom, the inner wall of the burner cap facing the base forms a gradually narrowing section. The connection between the first and second sections forms a gas mixing section, and the second section forms a diffusion section. By making the airflow more uniform, the stability of the burner cap's exhaust gas and the complete combustion of the flame are achieved, ultimately resulting in a significant improvement in both flame stabilization performance and flue gas cleanliness.

[0020] Preferably, the fire cap includes a cap body structure, the cap body structure includes a brim portion, the brim portion includes a groove portion, the cap body structure includes a second sidewall, the groove portion is disposed near the second sidewall, and the groove portion is lower than the top surface of the brim portion.

[0021] In this design, by extending the brim radially away from the temperature control probe of the flame cap, and connecting the end of the brim near the temperature control probe to the second sidewall, the overflow liquid can be collected at the brim when flowing down the second sidewall. The groove on the cap structure is located near the second sidewall and is lower than the top surface of the brim. After flowing down the sloping top surface of the flame cap, the overflow liquid can flow directly to the groove along the second sidewall, where it is collected and discharged to the overflow collection point, preventing the overflow liquid from spreading to other parts of the flame cap.

[0022] Preferably, the side of the groove closest to the temperature control probe is connected to the second sidewall.

[0023] Preferably, the top surface of the flame cap is located on the side of the groove portion near the center of the flame cap.

[0024] A cooker stove comprising an anti-dry-burning burner as described above.

[0025] The positive and progressive effects of this utility model are as follows:

[0026] By configuring the first chamber corresponding to the temperature control probe and connecting it to the mixing chamber formed by the burner cap and the upper sidewall of the base, with the connection point between the first chamber and the mixing chamber higher than the highest point of the burner cap's flame hole, the combustion gas can be collected and stably retained in the first chamber. This design fully utilizes the burner cap's own structure to form a physical heat insulation barrier, while further blocking the heat conduction path through the gas path connection between the chambers, thus achieving multiple heat insulation protection effects. This solution does not introduce additional complex components, effectively improving the thermal stability and detection accuracy of the temperature control probe in high-temperature environments while maintaining structural simplicity, thereby enhancing the overall system's reliability and service life, achieving a balance between structural simplification and performance optimization.

[0045] Temperature control probe 2

[0046] Base 3 Detailed Implementation

[0047] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0048] like Figure 1 As shown, this embodiment provides an anti-dry-burning burner 001, which includes a burner cap 1, a temperature control probe 2, and a base 3. The burner cap 1 is disposed on the upper end of the base 3 and together form a mixing chamber 13 for supplying gas to the burner hole 11. The inner side of the base 3 is provided with a cavity for accommodating the temperature control probe 2. A first chamber 12 is provided at the top of the burner cap 1. In the height direction, the first chamber 12 surrounds the temperature control probe 2. The first chamber 12 communicates with the mixing chamber 13. The communication position between the first chamber 12 and the mixing chamber 13 is higher than the highest point of the burner hole 11 of the burner cap 1.

[0049] In this embodiment, the first chamber 12 is correspondingly arranged with the temperature control probe 2 and connected to the mixing chamber 13 formed by the burner cap 1 and the upper sidewall of the base 3. The connection port is positioned above the highest point of the burner hole 11, allowing for stable collection and retention of the gas within the first chamber 12. This structure fully utilizes the burner cap body 16 to form a physical heat insulation barrier and blocks heat conduction pathways through the inter-chamber gas connection, achieving multiple layers of heat insulation protection. This solution does not introduce any additional complex components. While maintaining a simple overall structure, it effectively improves the thermal stability and measurement accuracy of the temperature control probe 2 in high-temperature environments, thereby enhancing the reliability and service life of the system and achieving a harmonious balance between structural simplification and performance improvement.

[0050] like Figures 1-2As shown, in this embodiment, the flame cap 1 includes a cap structure 14 and a flame cap body 16. The temperature control probe 2 is located in the middle of the flame cap 1, and the cap structure 14 is located at the top of the flame cap 1. The top of the flame cap body 16 is connected to the cap structure 14. The cap structure 14 includes a first sidewall 141 and a second sidewall 142. The first sidewall 141 is disposed on the side of the cap structure 14 near the temperature control probe 2 and surrounds the temperature control probe 2. The second sidewall 142 is disposed on the side of the cap structure 14 away from the temperature control probe 2. The first sidewall 141 and the second sidewall 142 extend downward along the top surface 15 of the cap structure 14, and the first sidewall 141 and the second sidewall 142 together form a... The first chamber 12 has a first sidewall 141 extending upwards away from the temperature control probe 2. The first sidewall 141 is located at the upper end of the inner sidewall of the base 3 facing the temperature control probe 2, and is connected to the inner sidewall of the base 3 facing the temperature control probe 2. The first sidewall 141 and the inner sidewall of the base 3 facing the temperature control probe 2 form a cavity with an opening that gradually expands upwards. The first sidewall 141 forms a funnel-shaped opening of the cavity, guiding the gas to diffuse away from the temperature control probe 2. This effectively guides the high-temperature flue gas to diffuse naturally outwards during its ascent, preventing local accumulation around the temperature control probe 2 and significantly reducing interference with the probe's detection accuracy. Simultaneously, this structure increases the airflow velocity in the upper part of the cavity where the temperature control probe 2 is located, helping to accelerate the discharge of stagnant flue gas within the cavity, further optimizing the stability of the detection environment and effectively reducing the detection failure rate of the temperature control probe 2.

[0051] In this embodiment, the cap structure 14 at the top of the flame cap 1 has a first sidewall 141 and a second sidewall 142, which together form a first chamber 12. The top of the flame cap 1 has a four-layer heat insulation structure surrounding the temperature control probe 2 in the horizontal direction. Along the direction close to the temperature control probe 2, there are the second sidewall 142, the first chamber 12, the second sidewall 142, and the gap between the second sidewall 142 and the temperature control probe 2. This four-layer heat insulation structure can effectively isolate the flame and high-temperature smoke from the flame hole 11 from the detection end of the temperature control probe 2. Compared with the single-layer heat insulation structure design in the prior art, the four-layer heat insulation structure provides a progressive heat control mode, which can fully reduce heat interference, thereby improving the detection accuracy of the temperature control probe 2 and improving the performance of the product.

[0052] like Figures 1-3As shown, in this embodiment, the cap structure 14 is located at the top of the flame cap 1. The top surface 15 of the flame cap 1 is the same as the top surface 15 of the cap structure 14. The height of the top surface 15 of the flame cap 1 decreases in the direction away from the temperature control probe 2. The top surface 15 of the flame cap 1 presents a slope that gradually slopes downward from the center outward in the radial direction. The outer surfaces of the first sidewall 141 and the second sidewall 142 are smoothly connected to the top surface 15 of the cap structure 14. The outer wall of the first chamber 12 has an upwardly convex Z-shaped structure. The cap structure 14 also includes a brim 143. The brim 143 extends radially away from the temperature control probe 2 in the burner cap 1. The end of the brim 143 closest to the temperature control probe 2 is connected to the second sidewall 142. The edge of the brim 143 is radially farther from the temperature control probe 2 than the outermost edge of the burner cap body 16 is. The edge of the brim 143 extends beyond the outer wall of the burner cap body 16, creating an outwardly expanding radial protection distance between the brim 143 and the temperature control probe 2. This structure ensures that any overflowing liquid will drip directly and naturally from the brim, effectively blocking its path backflow to the surface of the burner cap body 16 or seep into the burner holes 11, significantly reducing the risk of contamination of the burner cap body 16 and the probability of malfunctions caused by liquid accumulation. The brim portion 143 also includes a groove portion 1431, which surrounds the temperature control probe 2. The groove portion 1431 has a slope facing the overflow collection mechanism. A guide opening is provided in the area corresponding to the overflow collection mechanism, allowing liquid to flow into the overflow collection mechanism through the groove portion 1431. The groove portion 1431 is located near the second sidewall 142 and is lower than the top surface 15 of the brim portion 143. The side of section 1431 closest to the temperature control probe 2 is connected to the second sidewall 142. The top surface 15 of the flame cap 1 is located on the side of the groove section 1431 closest to the center of the flame cap 1. By ensuring that the outer surfaces of both the first sidewall 141 and the second sidewall 142 are smoothly connected to the top surface 15 of the cap structure 14, the overflow or moisture accumulated at the top of the inner sidewall of the flame cap 1 can be guided to the top surface 15 of the cap by the rising airflow, and then flow along its inclined surface to the designated overflow collection point. This design achieves effective overflow guidance, avoids the accumulation of dirt in critical parts, and thus helps to extend the service life of the flame cap 1.

[0053] In other embodiments, the groove portion 1431 may not fully cover the brim portion 143. The groove portion 1431 may be provided at a specific location, and the top surface 15 of the hat structure 14 may be tilted at the corresponding location. This will not be described in detail here.

[0054] like Figures 2-3As shown, the inner wall of the flame cap body 16 facing the base 3 includes a first segment 161 and a second segment 162. The first segment 161 is located below the second segment 162. The first segment 161 and the second segment 162 are arranged sequentially in the vertical direction and connected to each other. The first segment 161 extends from bottom to top along the direction close to the inner wall of the base 3. The second segment 162 is located at the upper end of the inner wall of the flame cap body 16 facing the base 3. The second segment 162 extends from bottom to top along the direction away from the inner wall of the base 3. In this embodiment, a connection is also provided at the junction of the first segment 161 and the second segment 162. There is a smooth section. The space corresponding to the first section 161 is the mixing chamber 13. The mixing chamber 13 gradually contracts from bottom to top, the gas pressure gradually increases, the flow rate slows down, and the gas is guided to gather upward. The smooth section serves as a transition for the gas to enter the first chamber 12. The gas flow velocity remains constant through this space. The space corresponding to the second section 162 is the first chamber 12. The cross-sectional dimensions of the first chamber 12 gradually expand from bottom to top due to the change in the extension direction of the second section 162, guiding the gas to enter from the mixing chamber 13 and stay in the first chamber 12, providing heat insulation for the gas.

[0055] In other embodiments, there may be multiple first segments 161 and second segments 162, and the connection may not have a smooth segment. For example, a groove segment may be provided to buffer and store the gas, so as to guide the gas from the mixing chamber 13 into the first chamber 12 and stay in the first chamber 12 more efficiently. This will not be described in detail here.

[0056] This embodiment also provides a stove, which includes the anti-dry-burning burner 001 as described above.

[0057] The stove can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the stove to perform corresponding operations, thereby realizing intelligent control of the stove and improving the user experience.

[0058] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
