Description

Technical Field

[0001] This invention relates to the field of cooktop technology, and in particular to a burner assembly and a cooktop. Background Technology

[0002] The central cavity of a temperature-controlled burner needs to accommodate the temperature control probe, therefore its inner ring gas chamber is designed as a ring structure. Currently, with the increasing market demand for high-efficiency cooktops, including temperature-controlled products, higher thermal efficiency is constantly being pursued. To improve the overall thermal efficiency of the burner, the diameter of the inner ring burner cap must be minimized, resulting in a significant compression of the width of the inner ring gas chamber. This narrow chamber structure easily leads to a series of problems, such as uneven circumferential gas output, excessively high flame intensity in some burner holes causing flame detachment, and localized temperature anomalies around the temperature control probe leading to misjudgments. Compared to non-temperature-controlled burners, the problem of uniform airflow distribution in the inner ring is particularly significant in temperature-controlled burners.

[0003] In existing technologies, traditional flow equalization plates or airflow buffer plates are typically used. For example, Chinese patent document CN108343965A discloses a structure with a partition and a sealing plane, with an opening in the middle to achieve vertical connection, which narrows the vertical connection channel and reduces the flow rate. However, this structure is not suitable for the annular gas chamber in a temperature-controlled burner because the annular gas chamber is small. Using partitions and flat sealing methods would hinder the normal flow of air, affect the ventilation rate, and reduce the burner's efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the uneven circumferential gas output in the narrow gas chamber of the prior art, especially on the side corresponding to the gas inlet of the gas chamber, which will cause a series of problems such as excessive local flame intensity and flame lift-off, and excessive local temperature around the probe leading to misjudgment. The present invention provides a burner assembly and a stove.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A burner assembly includes a burner cap, a base, and a burner port assembly. The burner cap and the base together form a gas chamber communicating with the burner port assembly. An inclined flow guide structure is provided on the inner wall of the gas chamber. The inclined flow guide structure is provided corresponding to the air inlet of the gas chamber, and the axial extension direction of the inclined flow guide structure is oriented away from the burner port assembly. The angle between the air outlet direction of the inclined flow guide structure and the inner wall of the gas chamber away from the burner port assembly along the direction close to the burner cap is an obtuse angle.

[0007] In this solution, by installing a sloping flow guide structure with its axis extending away from the burner assembly on the side of the gas chamber corresponding to the air inlet, the problem of uneven circumferential gas distribution caused by the narrow and elongated chamber can be effectively alleviated. Specifically, in the area corresponding to the air inlet of the gas chamber, the gas flow is usually concentrated, which can easily cause excessively high airflow velocity at the local burner, potentially leading to flame lift-off, unstable combustion, and abnormal temperature distribution around the flame detection probe, thus triggering system misjudgments. By adding this sloping flow guide structure, the gas can be guided to form a wall-attached flow on the inner wall of the chamber, significantly improving the uniformity of gas distribution in the circumferential and local areas. This structure not only plays a good role in stabilizing pressure and flow in the local burner area, but also enhances flame stability, effectively preventing flame lift-off and similar abnormal combustion phenomena, thereby improving the reliability and control accuracy of the overall combustion system.

[0008] Preferably, the burner assembly further includes a cantilever structure disposed on the outer wall surface of the gas chamber on the side of the gas inlet, the cantilever structure including a first end.

[0009] Preferably, the first end is located on the side of the cantilever structure facing the air intake direction, the first end is an inclined surface, and the angle between the first end and the airflow direction in the axial direction of the gas chamber is an acute angle.

[0010] Preferably, the vertical height of the cantilever structure is greater than the width of the gas chamber.

[0011] In this design, two independent diffuser-stabilizing chambers are formed by enclosing a diffuser cantilever, the inner and outer walls of the channel, and the connecting ribs of the airflow channel. When the airflow is accelerated and introduced through the aforementioned tapering guide section, it first forms a stable wall-attached flow close to the inner wall, and then enters the two diffuser-stabilizing chambers. During this process, the velocity of some airflows is significantly reduced, and the overall pressure within the chamber tends to stabilize, thus providing uniform and stable airflow conditions for the subsequent combustion process. Simultaneously, the inclined diffuser cantilever can guide the incoming flow from the mixing chamber away from the air inlet on its other side. This guiding effect not only avoids excessive local airflow concentration but also helps promote a uniform distribution of the flow field throughout the entire combustion chamber, further reducing the occurrence of unfavorable flow structures such as eddies or backflows, and improving the stability of the overall flow organization and combustion efficiency. This structural design effectively combines the dual functions of pressure stabilization and flow guidance, contributing to efficient and stable combustion.

[0012] Preferably, the angle formed between the first end and the outer wall of the gas chamber is in the range of 20° to 40°.

[0013] Preferably, the inclined flow guiding structure includes a first inclined surface and a second inclined surface. The first inclined surface is circumferentially disposed on the outer wall of the gas chamber, and the second inclined surface is circumferentially disposed on the inner wall of the gas chamber. The first inclined surface and the second inclined surface cooperate to form an airflow channel.

[0014] Preferably, the circumferential angle of the first inclined surface is in the range of 50° to 70°.

[0015] Preferably, the circumferential angle of the second inclined surface is in the range of 80° to 100°.

[0016] Preferably, the ratio of the radial width of the airflow channel to the cavity width of the gas chamber is in the range of 0.5 to 0.7.

[0017] In this design, the first and second inclined surfaces work together to form a gradually narrowing guide section. The airflow passes through this section, then suddenly expands, entering the pressure stabilizing chamber. The inclined guide structure directs the airflow to the inner wall, creating a wall-hugging flow. This enhances airflow resistance, effectively suppressing the local airflow velocity in the upper region of the gas chamber's inlet. Furthermore, the guide section lengthens the local airflow path, increasing friction loss and further reducing local velocity and flow rate. This structure achieves a second-level flow restriction in the circumferential direction, significantly alleviating the flow instability caused by excessively high airflow velocity and flow rate above the inlet.

[0018] Preferably, the burner assembly further includes a rib structure connected to the inner and outer walls of the gas chamber. The rib structure includes a first rib and a second rib. The horizontal height of the first rib corresponds to the air inlet of the gas chamber, and the horizontal height of the second rib corresponds to the inclined flow guide structure. The rib structure is evenly distributed along the circumference of the gas chamber.

[0019] In this design, a first rib is positioned at the same horizontal level as the inlet of the gas chamber. After entering the narrow cavity structure, the inner ring gas flows at a relatively high velocity near the outlet. When the airflow passes over the columnar protrusion within the cavity, this structure acts as an "airflow deceleration band," effectively reducing the airflow velocity by disturbing the local flow and promoting a more even pressure distribution within the cavity, thereby significantly improving the uniformity of the gas flow along the circumference. Furthermore, this columnar protrusion serves a dual purpose: its back is designed with threaded holes for installing fixing screws to reliably support the probe bracket, achieving an integrated design of flow control and structural installation, combining the functions of airflow velocity control and mechanical fixation.

[0020] Preferably, the burner assembly further includes a temperature control chamber for mounting a temperature control probe. The diameter of the end of the temperature control chamber near the air inlet is larger than the diameter of the middle section of the temperature control chamber, and the diameter of the middle section of the temperature control chamber is smaller than the diameter of the end of the temperature control chamber near the burner cap.

[0021] In this design, the diameter of the end of the temperature control chamber near the air inlet is larger than the diameter of the middle section, forming a shrinkage section at the lower end. The middle section is a pressure-stabilizing section. The diameter of the middle section is smaller than the diameter of the end of the temperature control chamber near the burner cap. The chamber near the top of the burner cap is an expansion section. This structure is similar in form and function to the ejector tube commonly found in burners, but their working principles are fundamentally different: traditional temperature control chambers rely on the momentum generated by high-speed jets at the nozzle of the ejector tube to eject and entrain surrounding air; while the temperature control chamber of this invention utilizes the negative pressure generated by combustion at the burner holes at the top of the burner cap to draw air from the outlet. Despite the different driving methods, both can enhance the air intake effect. This structure can effectively draw more air into the probe cavity, enhancing the cooling of the probe and removing accumulated heat; it also provides more secondary air to the burner hole area, thereby promoting complete combustion of the gas and improving combustion stability and efficiency.

[0022] Preferably, the temperature control chamber further includes a first cavity structure, which is disposed at the bottom of the temperature control chamber, and the vertical cross-sectional shape of the first cavity structure is a wedge shape that is larger at the bottom and smaller at the top.

[0023] Preferably, the top opening of the temperature control chamber has a bowl-shaped cross-section with the opening facing upwards.

[0024] In this design, the first cavity structure is designed with a wedge-shaped vertical cross-section, wider at the bottom and narrower at the top, which facilitates the insertion and installation of the probe holder. If the cavity structure were a cylindrical channel, the probe holder would easily become stuck, hindering installation. Furthermore, the temperature control chamber's top opening is designed with an upward-facing bowl shape. As gas flows through this structure, some of the dynamic pressure gradually converts into static pressure, causing the airflow velocity to decrease smoothly. This area effectively suppresses the influence of flame fluctuations and external environmental disturbances on the probe. This significantly improves the accuracy and stability of the probe's temperature measurement and reduces thermal stress fluctuations on the probe, thereby extending its service life and ensuring the long-term reliable operation of the combustion system.

[0025] A cooktop comprising a burner assembly as described above.

[0026] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0027] The positive and progressive effects of this invention are as follows:

[0028] By installing a sloping flow guide structure with its axis extending away from the burner assembly on the side of the gas chamber corresponding to the air inlet, the problem of uneven circumferential gas distribution caused by the narrow and elongated chamber can be effectively alleviated. Specifically, in the area corresponding to the air inlet of the gas chamber, the gas flow is usually more concentrated, which can easily cause excessively high airflow velocity at the local burner, potentially leading to flame lift-off, unstable combustion, and abnormal temperature distribution around the flame detection probe, thus triggering system misjudgments. By adding this sloping flow guide structure, the gas can be guided to form a wall-attached flow on the inner wall of the chamber, significantly improving the uniformity of gas distribution in the circumferential and local areas. This structure not only plays a good role in stabilizing pressure and flow in the local burner area, but also enhances flame stability, effectively preventing flame lift-off and similar abnormal combustion phenomena, thereby improving the reliability and control accuracy of the overall combustion system.

[0052] The present invention is further illustrated below by way of embodiments, but the invention is not limited to the scope of the embodiments described herein. Experimental methods in the following embodiments that do not specify specific conditions were performed according to conventional methods and conditions, or as selected according to the product instructions.

[0053] like Figures 1-2 As shown, this embodiment provides a burner assembly 001, which includes a burner cap 1, a base 2, and a burner orifice assembly 3. The burner cap 1 and the base 2 together form a gas chamber 4 communicating with the burner orifice assembly 3. An inclined flow guide structure 42 is provided on the inner wall 41 of the gas chamber 4. The inclined flow guide structure 42 is provided corresponding to the air inlet 43 of the gas chamber 4, and the axial extension direction of the inclined flow guide structure 42 is directed away from the burner orifice assembly 3. The angle between the outlet direction of the inclined flow guide structure 42 and the inner wall 41 of the gas chamber 4 away from the burner orifice assembly 3 along the direction close to the burner cap 1 is an obtuse angle. By providing an inclined flow guide structure 42 with its axial extension direction directed away from the burner orifice assembly 3 on the side of the gas chamber 4 corresponding to the air inlet 43, the problem of uneven circumferential gas distribution caused by the narrow and long cavity can be effectively alleviated. By adding such an inclined flow guide structure 42, the gas can be guided to form a wall-adhering flow on the inner wall 41 of the cavity, significantly improving the uniformity of gas distribution in the circumferential and local areas. This structure not only provides good pressure and flow stabilization for the local flame hole area, but also enhances flame stability and effectively prevents flame lift-off and similar abnormal combustion phenomena, thereby improving the reliability and control accuracy of the overall combustion system.

[0054] like Figures 1-2As shown, in this embodiment, the inclined flow guiding structure 42 includes a first inclined surface 421 and a second inclined surface 422. The first inclined surface 421 is circumferentially disposed on the outer wall 45 of the gas chamber 4, and the second inclined surface 422 is circumferentially disposed on the inner wall 41 of the gas chamber 4. The first inclined surface 421 and the second inclined surface 422 cooperate to form an airflow channel. The radial positions of the first inclined surface 421 and the second inclined surface 422 are correspondingly arranged. The inclination angles of the opposite inclined surfaces of the first inclined surface 421 and the second inclined surface 422 are the same. The horizontal widths of the first inclined surface 421 and the second inclined surface 422 are the same. The circumferential setting angle range of the first inclined surface 421 is 50°~70°, and the circumferential setting angle range of the second inclined surface 422 is 80°~100°. The ratio of the radial width of the airflow channel to the cavity width of the gas chamber 4 is 0.5~0.7. The first inclined surface 421 and the second inclined surface 422 work together to form an inclined, tapering guide section. The airflow passes through this tapering guide section, then suddenly expands, entering the pressure stabilizing chamber. The inclined guide structure 42 directs the airflow to the inner wall, forming a wall-hugging flow. On the one hand, this increases the airflow resistance, thereby effectively suppressing the local airflow velocity in the upper region of the inlet 43 of the gas chamber 4. On the other hand, the design of this guide section extends the local airflow path, increases friction loss, and further promotes the reduction of local velocity and flow rate. This structure achieves a second-level flow restriction effect in the circumferential direction, alleviating the flow instability problem caused by excessively high airflow velocity and flow rate above the inlet 43.

[0055] In other embodiments, the inclined flow guiding structure 42 may also include multiple inclined surfaces, and the multiple inclined surfaces may not be interconnected, or the inclination angles and widths of the multiple inclined surfaces may be inconsistent, so as to achieve the effect of flow guiding and pressurization, which will not be elaborated here.

[0056] like Figures 1-2As shown, the burner assembly 001 also includes a cantilever structure 44, which is disposed on the outer wall 45 surface of the gas chamber 4 on one side of the air inlet 43. The cantilever structure 44 includes a first end 441, which is disposed on the side of the cantilever structure 44 facing the air inlet direction. The first end 441 is an inclined surface. In this embodiment, the inclination angle of the first end 441 is the same as the inclination angle of the first inclined surface 421, and the angle between the first end 441 and the airflow direction in the axial direction of the gas chamber 4 is an acute angle. The angle between the first end 441 and the outer wall 45 of the gas chamber 4 ranges from 20° to 40°. Preferably, there are two cantilever structures 44. The aforementioned first inclined surface 421 is positioned between the two cantilever structures 44 and connected to the side walls of the two cantilever structures 44. The top height of the cantilever structure 44 is higher than the top height of the first inclined surface 421. The horizontal width of the cantilever structure 44 corresponds to the horizontal width of the first inclined surface 421, and the vertical height of the cantilever structure 44 is greater than the width of the gas chamber. Two independent diffuser-stabilizing chambers are formed by the diffuser cantilever, the inner and outer walls of the channel, and the connecting ribs of the airflow channel. When the airflow is accelerated and introduced through the aforementioned tapered guide section, it first forms a stable wall-attached flow close to the inner wall, and then enters the two diffuser-stabilizing chambers. During this process, some airflow velocity decreases, and the overall pressure inside the chamber tends to stabilize, thus providing uniform and stable airflow conditions for the subsequent combustion process. Simultaneously, the other side of the inclined diffuser cantilever can guide the incoming flow from the mixing chamber away from the inlet 43. This guiding effect not only avoids excessive local airflow concentration, but also helps to promote the uniform distribution of the flow field in the entire gas chamber 4, thereby improving the stability of the overall flow organization and combustion efficiency.

[0057] In other embodiments, the number of cantilever structures 44 can be more than two. The tilt angle of the first end 441 of the cantilever structure 44 may not be the same as the tilt angle of the first inclined surface 421. The horizontal width of the cantilever structure 44 may be greater than the horizontal width of the first inclined surface 421. The first inclined surface 421 may not be connected to the cantilever structure 44. This will not be elaborated further here.

[0058] like Figures 3-4As shown, the burner assembly 001 also includes a rib structure 5, which is connected to the inner wall 41 and outer wall 45 of the gas chamber 4. The rib structure 5 includes a first rib 51 and a second rib 52. The horizontal height of the first rib 51 corresponds to the air inlet 43 of the gas chamber 4, and the horizontal height of the second rib 52 corresponds to the inclined flow guide structure 42. In this embodiment, the first rib 51 and the second rib 52 connect the inner wall 41 and the outer wall 45 of the gas chamber 4. There are four first ribs 51, which are evenly distributed at the same horizontal height as the air outlet of the gas chamber 4. There are four second ribs 52, which are evenly distributed at the same horizontal height as the inclined flow guide structure 42. Some ribs penetrate the first inclined surface 421, and the cross-sectional dimension of the second rib 52 is smaller than that of the first rib 51. The rib structure 5 is evenly distributed along the circumference of the gas chamber 4. In this embodiment, a first rib 51 is provided at the same horizontal height as the air inlet 43 of the gas chamber 4. When the airflow passes through the columnar protrusion provided in the chamber, this structure can act as an "airflow deceleration strip," effectively reducing the airflow velocity by disturbing the local flow and promoting a balanced distribution of pressure within the chamber, thereby improving the uniformity of the gas flow along the circumference. In addition, the columnar protrusion has a dual function: its back is designed with threaded holes for installing fixing screws to reliably support the probe bracket.

[0059] In other embodiments, baffle structures or other turbulence structures can be set in the gas chamber to reduce the airflow velocity at the outlet, thereby preventing problems such as excessive flame lift-off in local flame holes and excessively high local temperatures around the probe. The number of rib structures 5 can also be multiple, which will not be elaborated here.

[0060] like Figures 1-3As shown, in this embodiment, the burner assembly 001 further includes a temperature control chamber 6, which is used to install a temperature control probe. The diameter of the end of the temperature control chamber 6 near the air inlet 43 is larger than the diameter of the middle section of the temperature control chamber 6, and the diameter of the middle section of the temperature control chamber 6 is smaller than the diameter of the end of the temperature control chamber 6 near the burner cap 1. The temperature control chamber 6 also includes a first cavity structure 61, which is disposed at the bottom of the temperature control chamber 6. The vertical cross-sectional shape of the first cavity structure 61 is a wedge-shaped structure with a larger bottom and a smaller top, and the cross-sectional shape of the top opening of the temperature control chamber 6 is a bowl-shaped structure with the opening facing upwards. By setting the diameter of the end of the temperature control chamber 6 near the air inlet 43 to be larger than the diameter of the middle section of the temperature control chamber 6, a shrinkage section is formed at the lower end of the temperature control chamber 6, and the middle section is a pressure stabilizing section. The diameter of the middle section of the temperature control chamber 6 is smaller than the diameter of the end of the temperature control chamber 6 near the burner cap 1, and the chamber of the temperature control chamber 6 near the top of the burner cap 1 is an expansion section. The temperature control chamber 6 of this invention utilizes the negative pressure generated by the combustion of the flame holes at the top of the burner cap 1 to draw air from the outlet position, thereby enhancing the air intake effect. The structure of this invention can effectively draw more air into the probe cavity, which on the one hand strengthens the cooling of the probe and removes the heat accumulated around it in time; on the other hand, it can also supplement more secondary air to the flame hole area of ​​the burner cap 1, thereby promoting complete combustion of the gas and improving combustion stability and efficiency. In addition, this embodiment sets the vertical cross-sectional shape of the first cavity structure 61 to a wedge shape with a larger bottom and a smaller top, which facilitates the insertion and installation of the probe bracket. By setting the cross-sectional shape of the top opening of the temperature control chamber 6 to an upward-facing bowl shape, when the gas flows through this structure, part of the dynamic pressure is gradually converted into static pressure, causing the airflow velocity to decrease smoothly. This area can effectively suppress the influence of flame fluctuations and external environmental disturbances on the probe. On the one hand, it significantly improves the accuracy and stability of the probe temperature measurement, and on the other hand, it reduces the thermal stress fluctuations that the probe bears, thereby extending its service life and ensuring the long-term reliable operation of the combustion system.

[0061] In other embodiments, the vertical cross-sectional shape of the temperature control chamber 6 can also be other shapes that can reduce the temperature fluctuations that the probe is subjected to. The top cross-sectional shape of the temperature control chamber 6 near the burner cap 1 can also be parabolic, arc-shaped, etc., which can utilize the negative pressure generated by the combustion of the burner holes at the top burner cap 1 to draw air from the outlet position and enhance the shape of the air intake. These will not be elaborated further here.

[0062] like Figures 1-4 As shown, this embodiment also provides a stove, which includes the burner assembly 001 as described above.

[0063] 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.
