Description

Technical Field

[0001] This utility model relates to the technical field of kitchen utensils, specifically to a burner and a stove. Background Technology

[0002] Gas stoves have become an indispensable household appliance in people's daily lives.

[0003] Currently, in order to ensure the combustion efficiency of gas stoves, three-chamber burners are generally used. A three-chamber burner can include an inner ring combustion chamber, a middle ring combustion chamber, and an outer ring combustion chamber. By introducing gas into each chamber, more uniform combustion and higher combustion efficiency can be achieved.

[0004] However, three-chamber burners typically employ a multi-layered mixing structure in the direction perpendicular to the mounting plane, such as stacking the middle and outer ring combustion chambers. This stacked three-chamber burner structure is complex, has high manufacturing costs, and is difficult to clean and maintain, which greatly affects the user experience. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a wind turbine assembly is provided, the technical solution of which is as follows.

[0006] The burner includes a burner seat and a first burner cap. The burner seat has a middle annular mixing chamber and an outer annular mixing chamber, with the outer annular mixing chamber at least partially surrounding the outer side of the middle annular mixing chamber. The first burner cap is disposed on the burner seat and has a first cap portion and a second cap portion. The first cap portion and the middle annular mixing chamber enclose a middle annular mixing chamber to form a middle annular mixing chamber, and the second cap portion and the outer annular mixing chamber enclose an outer annular mixing chamber to form an outer annular mixing chamber.

[0007] The burner of this utility model has a first flame cap that can cooperate with the middle ring mixing chamber and the outer ring mixing chamber on the burner seat to form a middle ring mixing chamber and an outer ring mixing chamber. The middle ring mixing chamber and the outer ring mixing chamber can be arranged sequentially from the inside to the outside. In this way, not only can two mixing chambers be covered at the same time with one flame cap, but the burner's burner seat is also constructed with a single-layer structure, which effectively simplifies the structure of the burner, reduces the manufacturing difficulty and cost of the burner, reduces the dead corners of the burner, facilitates cleaning and maintenance by the user, and greatly improves the user experience.

[0008] For example, the burner holder has a bottom wall with a first air inlet and a second air inlet. The first air inlet is connected to the middle annular mixing chamber, and the second air inlet is connected to the outer annular mixing chamber. Thus, by supplying gas to the middle and outer annular mixing chambers separately, it can be ensured that the gas and air are fully mixed in different areas, thereby improving the combustion efficiency of the burner. Furthermore, the gas supply to the middle and outer annular mixing chambers can be controlled through independent air inlets, allowing for dynamic adjustment of the gas supply to the middle and outer annular mixing chambers according to the actual combustion process, to achieve optimal combustion performance.

[0009] For example, the first and second air inlets are symmetrically arranged relative to the center of the burner base. This avoids interference between the gas supply pipes connected to the first and second air inlets due to their close proximity. Furthermore, when the burner is used in a stove, the first and second air inlets can be directly connected to the three-way valve body via gas supply pipes, eliminating the need for additional connecting pipes and effectively reducing the manufacturing cost and complexity of the stove.

[0010] For example, the burner holder has an inner side wall, a partition wall, and an outer side wall arranged from the inside to the outside on the bottom wall. The inner side wall, the bottom wall, and the partition wall enclose a middle annular mixing chamber, and the partition wall, the bottom wall, and the outer side wall enclose an outer annular mixing chamber. In this way, stratified combustion of the burner can be achieved, which not only improves the combustion efficiency of the burner but also simplifies the structure of the burner.

[0011] For example, the partition wall is provided with a clearance groove, which communicates with the outer ring mixing chamber. The second air inlet is located at the bottom of the clearance groove, and the top of the clearance groove forms the partition wall. The projection of the partition wall onto the plane of the bottom wall at least partially covers the second air inlet. In this way, not only can the first air inlet and the second air inlet be symmetrically arranged relative to the center of the ignition seat, but the fuel gas can also be guided into the outer ring mixing chamber through the second air inlet. This avoids the occurrence of redundant structures in the partition wall, effectively simplifies the structure of the partition wall, and reduces the manufacturing and maintenance costs of the partition wall.

[0012] For example, the lower surface of the first burner cap is provided with a groove at the connection between the first cap portion and the second cap portion, and at least part of the top of the partition wall is embedded in the groove. In this way, the connection between the first cap portion and the second cap portion can be recessed in a direction away from the burner seat to form an annular groove. When the first burner cap is installed on the burner seat, the top of the partition wall can be embedded in the groove, thereby ensuring the firmness and stability of the connection between the first burner cap and the burner seat, and thus improving the reliability of the burner.

[0013] For example, the burner further includes a connector, with the second air inlet extending through the connector. The bottom wall of the burner seat has an inwardly recessed cavity, and at least a portion of the connector is embedded within the cavity to form surface contact with the bottom of the cavity. This not only ensures surface contact between the connector and the bottom of the cavity, thus guaranteeing the stability and secureness of the second air inlet installation, but also ensures that the installation height of the second air inlet is consistent with that of the first air inlet, thereby guaranteeing the flatness of the lower surface of the burner seat.

[0014] For example, a first flame outlet is formed on the first cover portion, communicating with the middle annular mixing chamber, and a second flame outlet is formed on the second cover portion, communicating with the outer annular mixing chamber. The shape of the first flame outlet and the shape of the second flame outlet are constructed to be at least one of the following: circular and elongated. In this way, the shape of the first flame outlet and the shape of the second flame outlet can be determined according to different usage scenarios and usage requirements, effectively improving the practicality and flexibility of the burner.

[0015] For example, the burner also includes a support and an injector tube, with the injector tube passing through the support and the ignition seat disposed on the support and connected to the injector tube. In this way, the support not only connects the injector tube and the ignition seat, but also prevents relative displacement between the injector tube and the ignition seat, thus giving the burner a stable structure and effectively ensuring the overall robustness of the burner.

[0016] For example, the ejector tube includes an outer ring ejector tube, a middle ring ejector tube, and an inner ring ejector tube. The middle ring ejector tube is connected to the middle ring mixing chamber, the outer ring ejector tube is connected to the outer ring mixing chamber, and the inner ring ejector tube is located within the area surrounding the burner seat. The burner also includes a second burner cap, the air inlet of which is connected to the inner ring ejector tube. Thus, the outer ring ejector tube, middle ring ejector tube, and inner ring ejector tube can each be connected to the burner seat, and the outer ring ejector tube and middle ring ejector tube can be symmetrically arranged relative to the inner ring ejector tube. This optimizes the structural layout of the burner, simplifying the assembly steps between the burner and other components in the cooktop when applied to a stove, reducing the manufacturing cost and difficulty of the cooktop. Furthermore, the second burner cap can be placed on the inner ring ejector tube, making the overall burner a three-chamber burner. A three-chamber burner allows heat to be transferred more evenly to the cookware, further improving the burner's combustion efficiency.

[0017] For example, an airflow gap L is formed between the bottom wall of the burner seat and the support, and the value of the airflow gap L ranges from 5 to 25 mm. In this way, an airflow gap can be formed between the bottom wall of the burner seat and the support, so that air from the external environment can flow into the space between the second burner cap and the first burner cap through the airflow gap. The air flowing in through the airflow gap can come into more complete contact with the flame generated by the burner, which significantly improves the combustion efficiency of the burner.

[0018] According to another aspect of the present invention, a stove is also provided, including a bottom shell, a panel and a burner as described above. The bottom shell forms an installation cavity with an opening, the panel covers the opening, the panel has a through hole, the burner passes through the through hole, and part of the burner is located inside the installation cavity and part of the burner is located outside the installation cavity.

[0019] The stove of the present invention includes the burner as described above. Since the burner has the beneficial effects described above, the stove including the burner as described above must also have the beneficial effects described above.

[0020] The advantages and features of this utility model will be described in detail below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0031] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0032] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0033] One embodiment of this utility model provides a burner with a single-layer structure, which effectively simplifies the burner's structure, reduces manufacturing difficulty and cost, and facilitates cleaning and maintenance by the user. The following will describe in detail a burner according to an embodiment of this utility model with reference to the accompanying drawings.

[0034] like Figure 1 and Figure 2 As shown, the burner includes a burner base 1 and a first burner cap 2. The burner base 1 has a middle annular mixing chamber 11 and an outer annular mixing chamber 12, with the outer annular mixing chamber 12 at least partially surrounding the outer side of the middle annular mixing chamber 11. The first burner cap 2 is disposed on the burner base 1 and has a first cap portion 21 and a second cap portion 22. The first cap portion 21 and the middle annular mixing chamber 11 enclose a middle annular mixing cavity 4, and the second cap portion 22 and the outer annular mixing chamber 12 enclose an outer annular mixing cavity 5.

[0035] The first cover portion 21 and the second cover portion 22 can be connected to form the first flame cap 2. The second cover portion 22 can be located outside the first cover portion 21. The first cover portion 21 and the second cover portion 22 can be detachably connected or integrally formed, preferably integrally formed. Detachable connection can include plug-in connection or adhesive connection, etc., which are not specifically limited in this application.

[0036] The ignition base 1 can be disc-shaped, and the disc-shaped ignition base 1 can be provided with a middle ring mixing chamber 11 and an outer ring mixing chamber 12 in sequence along its radial direction. When the first flame cap 2 is placed on the ignition base 1, it can form a middle ring mixing chamber 4 and an outer ring mixing chamber 5 respectively. Each of the above mixing chambers can be connected to the gas source, and the gas can be fully mixed with the combustion-supporting gas in the mixing chamber, thereby ensuring the combustion efficiency of the burner.

[0037] The aforementioned middle ring mixing chamber 4 and outer ring mixing chamber 5 can be arranged sequentially from the inside to the outside along the radial direction of the burner seat 1. This avoids the situation where the mixing chambers are stacked on top of each other, resulting in a more complex structure and higher height of the burner, which in turn leads to a higher cost of the burner and a smaller number of applicable stoves when the burner is applied to stoves.

[0038] In this invention, the first flame cap 2 can cooperate with the middle ring mixing chamber 11 and the outer ring mixing chamber 12 on the burner seat 1 to form the middle ring mixing chamber 4 and the outer ring mixing chamber 5. The middle ring mixing chamber 4 and the outer ring mixing chamber 5 can be arranged sequentially from the inside to the outside. In this way, not only can two mixing chambers be covered at the same time using one flame cap, but the burner seat 1 is also constructed as a single-layer structure, which effectively simplifies the structure of the burner, reduces the manufacturing difficulty and cost of the burner, reduces the dead corners of the burner, facilitates cleaning and maintenance by the user, and greatly improves the user experience.

[0039] In some embodiments, such as Figures 2 to 4 As shown, the ignition base 1 has a bottom wall 13, on which a first air inlet 131 and a second air inlet 132 are provided. The first air inlet 131 is connected to the middle ring mixing chamber 4, and the second air inlet 132 is connected to the outer ring mixing chamber 5.

[0040] The first air inlet 131 and the second air inlet 132 can be circular or elliptical in shape, and this application does not specifically limit this, but elliptical is preferred. The elliptical first air inlet 131 can reduce the width of the outer ring mixing chamber 5 while ensuring the cross-sectional area of ​​the first air inlet 131, thereby ensuring the intake efficiency of the gas. Similarly, the elliptical second air inlet 132 also has the above-mentioned beneficial effects, which will not be elaborated further here.

[0041] In the above embodiment, gas can be supplied to the middle annular mixing chamber 4 through the first air inlet 131 and to the outer annular mixing chamber 5 through the second air inlet 132. By supplying gas to the middle annular mixing chamber 4 and the outer annular mixing chamber 5 separately, it can be ensured that the gas and air are fully mixed in different areas, thereby improving the combustion efficiency of the burner. Furthermore, the gas supply to the middle annular mixing chamber 4 and the outer annular mixing chamber 5 can be controlled through independent air inlets, allowing for dynamic adjustment of the gas supply to the middle annular mixing chamber 4 and the outer annular mixing chamber 5 according to the actual combustion process, thus achieving the best combustion effect.

[0042] In some embodiments, such as Figure 2 and Figure 4 As shown, the first air inlet 131 and the second air inlet 132 are symmetrically arranged relative to the center of the fire distribution seat 1.

[0043] In the above embodiments, the first air inlet 131 and the second air inlet 132 can be symmetrically arranged relative to the center of the burner base 1. This avoids interference between the gas supply pipes connected to the first air inlet 131 and the second air inlet 132 due to their close proximity. Furthermore, when the burner is applied to a stove, the first air inlet 131 and the second air inlet 132 can be directly connected to the three-way straight-insertion valve body via gas supply pipes, eliminating the need for additional connecting pipes and effectively reducing the manufacturing cost and difficulty of the stove.

[0044] In some embodiments, such as Figure 2 and Figure 3 As shown, the ignition base 1 has an inner wall 15, a partition wall 14 and an outer wall 16 arranged from the inside to the outside of the bottom wall 13. The inner wall 15, the bottom wall 13 and the partition wall 14 enclose a middle ring mixing chamber 11, and the partition wall 14, the bottom wall 13 and the outer wall 16 enclose an outer ring mixing chamber 12.

[0045] The aforementioned partition wall 14 can be annular. When it is installed on the bottom wall 13 of the ignition seat 1, it can cooperate with the inner side wall 15 and the outer side wall 16 to form an annular middle annular mixing chamber 11 and an annular outer annular mixing chamber 12, respectively.

[0046] In the above embodiments, the inner wall 15, the bottom wall 13 and the partition wall 14 can be enclosed to form the middle ring mixing chamber 11, and the partition wall 14, the bottom wall 13 and the outer wall 16 can be enclosed to form the outer ring mixing chamber 12. In this way, the stratified combustion of the burner can be realized, which not only improves the combustion efficiency of the burner, but also simplifies the structure of the burner.

[0047] In some embodiments, such as Figure 2 and Figure 3As shown, the partition wall 14 is provided with a relief groove 141, which is connected to the outer ring mixing chamber 12. The second air inlet 132 is located at the bottom of the relief groove 141, and the top of the relief groove forms the partition wall 14. The projection of the partition wall 14 onto the plane where the bottom wall 13 is located at least partially covers the second air inlet 132.

[0048] The partition wall 14 and the clearance groove 141 can be detachably connected or integrally formed. The detachable connection can include adhesive connection or plug-in connection. Preferably, it is integrally formed. Specifically, the side wall of the partition wall 14 can be recessed towards the first air inlet 131 to form the clearance groove 141, thereby effectively ensuring the structural strength of the partition wall 14.

[0049] In the above embodiment, the projection of the partition wall 14 onto the plane of the bottom wall 13 can at least partially cover the second air inlet 132. This not only ensures that the first air inlet 131 and the second air inlet 132 can be symmetrically arranged relative to the center of the ignition seat 1, but also guides the gas through the second air inlet 132 into the outer ring mixing chamber 5, avoiding the occurrence of redundant structures in the partition wall 14, effectively simplifying the structure of the partition wall 14, and reducing the manufacturing and maintenance costs of the partition wall 14.

[0050] In some embodiments, such as Figure 5 As shown, a slot 222 is provided on the lower surface of the first flame cover 2 at the connection between the first cover part 21 and the second cover part 22, and at least part of the top of the partition wall 14 is embedded in the slot 222.

[0051] In the above embodiment, the connection between the first cover portion 21 and the second cover portion 22 can be recessed in the direction away from the burner seat 1 to form an annular groove 222. When the first burner cover 2 is installed on the burner seat 1, the top of the partition wall 14 can be embedded in the groove 222, thereby ensuring the firmness and stability of the connection between the first burner cover 2 and the burner seat 1, and thus improving the reliability of the burner.

[0052] In some embodiments, such as Figure 4 As shown, the burner also includes a connector 18, a second air inlet 132 passing through the connector 18, and the bottom wall of the burner seat 1 has an inwardly recessed cavity 17. At least part of the connector 18 is embedded in the cavity 17 to form a surface contact with the bottom of the cavity 17.

[0053] The ignition base 1 can be manufactured by die casting of aluminum. The first air inlet 131 can be integrally formed on the ignition base 1. The ignition base 1 manufactured by the above processing method not only has high manufacturing efficiency, but also low manufacturing cost.

[0054] The bottom wall of the ignition base 1 can be recessed inward to form a cavity 17. At least part of the connecting body 18 can be detachably connected to the cavity 17 of the ignition base 1. Specifically, the connecting body 18 and the cavity 17 of the ignition base 1 can be snap-fitted together or connected by fasteners such as screws.

[0055] In the above embodiment, the second air inlet 132 can be formed on the connector 18, and at least a portion of the connector 18 can be embedded in the cavity 17 of the ignition base 1. This ensures not only surface contact between the connector 18 and the bottom of the cavity 17, thus guaranteeing the stability and firmness of the second air inlet 132 installation, but also ensures that the installation height of the second air inlet 132 is consistent with the installation height of the first air inlet 131, thereby ensuring the flatness of the lower surface of the ignition base 1.

[0056] In some embodiments, such as Figure 5 As shown, a first flame outlet 211 communicating with the middle ring mixing chamber 4 is formed on the first cover portion 21, and a second flame outlet 221 communicating with the outer ring mixing chamber 5 is formed on the second cover portion 22. The shape of the first flame outlet 211 and the shape of the second flame outlet 221 are at least one of the following: circular and elongated.

[0057] When the burner is in the combustion state, the first flame outlet 211 on the first cover 21 and the second flame outlet 221 on the second cover 22 can evenly disperse the flame into multiple small flames, thereby increasing the combustion area of ​​the burner and improving the heating efficiency of the burner.

[0058] A circular first flame outlet 211 or a circular second flame outlet 221 can provide a higher flame height, making it suitable for applications where the distance between the flame outlet and the cookware above the burner is relatively large. An elongated first flame outlet 211 or a rectangular second flame outlet 221 can provide a larger heating area, making it suitable for applications where the flame outlet and the cookware above the burner are relatively close. Therefore, the shape of the first flame outlet 211 is preferably elongated, and the shape of the second flame outlet 221 is preferably circular.

[0059] In the above embodiments, the shape of the first flame outlet 211 and the shape of the second flame outlet 221 can be determined according to different usage scenarios and usage requirements, effectively improving the practicality and flexibility of the burner.

[0060] In some embodiments, such as Figure 2 , Figure 6 and Figure 7 As shown, the burner also includes a support 6 and an ejector tube 7. The ejector tube 7 passes through the support 6, and the ignition seat 1 is disposed on the support 6 and connected to the ejector tube 7.

[0061] Specifically, the ejector tube 7 can be installed on the bracket 6, and one end of the ejector tube 7 can be connected to the gas source, while the other end of the ejector tube 7 can be connected to the first air inlet 131, the second air inlet 132, etc. of the burner. The ignition distribution seat 1 can evenly distribute the gas delivered by the ejector tube 7 to the middle ring mixing chamber 4 and the outer ring mixing chamber 5.

[0062] Both the ejector tube 7 and the support 6 can be made of stainless steel. Stainless steel has excellent oxidation resistance and corrosion resistance, which significantly improves the service life of the burner. In addition, the surface of stainless steel is smooth, does not easily adhere to oil and dust, and is easy to clean and maintain.

[0063] In the above embodiments, the bracket 6 can not only connect the injector tube 7 and the ignition seat 1, but also prevent relative displacement between the injector tube 7 and the ignition seat 1. This can give the burner a stable structure and effectively ensure the overall robustness of the burner.

[0064] In some embodiments, such as Figure 2 and Figure 6 As shown, the ejector tube 7 includes an outer ring ejector tube 71, a middle ring ejector tube 72, and an inner ring ejector tube 73. The middle ring ejector tube 72 is connected to the middle ring mixing chamber 4, the outer ring ejector tube 71 is connected to the outer ring mixing chamber 5, and the inner ring ejector tube 73 is located in the area surrounding the burner seat 1. The burner also includes a second burner cap 3, and the air inlet of the second burner cap 3 is connected to the inner ring ejector tube 73.

[0065] The outlet end of the outer ring ejector tube 71 is connected to the second air inlet 132 of the outer ring mixing chamber 5, and the outlet end of the middle ring ejector tube 72 is connected to the first air inlet 131 of the middle ring mixing chamber 4. The outer wall of the inner ring ejector tube 73 is fixedly connected to the bracket 6, and the outlet end of the inner ring ejector tube 73 is exposed above the bracket 6. The second flame cap 3 can be directly placed on the inner ring ejector tube 73; or the bracket 6 is provided with an inner ring connecting seat, the inner ring ejector tube 73 is connected to the bracket 6 and communicates with the inner ring connecting seat, and the second flame cap 3 is placed on the inner ring connecting seat.

[0066] The outer ring ejector tube 71 and the middle ring ejector tube 72 can be symmetrically arranged relative to the inner ring ejector tube 73. The distance between the outer ring ejector tube 71 and the inner ring ejector tube 73, as well as the distance between the middle ring ejector tube 72 and the inner ring ejector tube 73, can both be 40 mm. In this way, when the burner is applied to the stove, one end of the ejector tube 7 can be directly connected to the burner seat 1, and the other end can be directly connected to the three-way straight-insertion valve body, without the need to set up other connecting pipes, which further reduces the manufacturing cost and manufacturing difficulty of the stove.

[0067] In the above embodiment, the outer ring ejector tube 71 and the middle ring ejector tube 72 can be connected to the burner base 1 respectively. This optimizes the structural layout of the burner and simplifies the assembly process between the burner and other components in the stove, reducing manufacturing costs and difficulty. Furthermore, the second burner cap 3 is connected to the inner ring ejector tube 73, making the burner a three-chamber burner. A three-chamber burner allows for more even heat distribution to the cookware, further improving combustion efficiency.

[0068] In some embodiments, such as Figure 7 As shown, an airflow gap L is formed between the bottom wall 13 of the fire distribution seat 1 and the support 6, and the value of the airflow gap L ranges from 5 to 25 mm.

[0069] Specifically, the airflow gap L ranges from 5 mm to 25 mm, for example, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, etc., preferably 10 mm.

[0070] In the above embodiment, an airflow gap can be formed between the bottom wall 13 of the burner seat 1 and the support 6, so that air from the external environment can flow into the space between the first burner cap 2 and the second burner cap 3 through the airflow gap. The air flowing in through the airflow gap can come into more full contact with the flame generated by the burner, which significantly improves the combustion efficiency of the burner.

[0071] According to another aspect of the present invention, a stove is also provided, including a bottom shell, a panel and a burner as described above. The bottom shell forms an installation cavity with an opening, the panel covers the opening, the panel has a through hole, the burner passes through the through hole, and part of the burner is located inside the installation cavity and part of the burner is located outside the installation cavity.

[0072] Specifically, the panel can be a glass panel or a metal panel. The panel can be fitted onto the bottom shell to form a mounting cavity. Some burners can be placed inside the mounting cavity, and some burners can extend out of the mounting cavity through through holes to heat cookware and other items.

[0073] The stove of the present invention includes the burner as described above. Since the burner has the beneficial effects described above, the stove including the burner as described above must also have the beneficial effects described above.
