Description

Technical Field

[0001] This application relates to the technical field of gas stoves, specifically to a burner for a gas stove and a gas stove. Background Technology

[0002] Gas stoves are among the most commonly used kitchen appliances in households, and the performance of their burners directly affects their thermal efficiency and user experience. Existing gas stove burners typically consist of an injector and a burner cap. The injector introduces gas into the burner, while the burner cap has multiple flame holes through which the gas is ejected and burned, thus heating the cookware. In current technology, the burner cap and injector are mostly fixedly connected, making angle adjustment impossible. This results in uncontrollable gas ejection direction and low heat utilization.

[0003] Therefore, there is still a real need for continued structural improvements to burners. Utility Model Content

[0004] In view of this, the purpose of embodiments of this application is to provide an improved burner for a gas stove and an improved gas stove, so as to overcome at least one of the above-mentioned disadvantages and / or other possible disadvantages not mentioned herein.

[0005] According to a first aspect of this application, a burner for a gas stove is provided, the burner comprising: an ejector assembly having an ejector body for guiding gas, the ejector body having a vertical guide portion; a central portion communicating with the vertical guide portion; and a burner cap assembly communicating with the ejector body, the burner cap assembly having a plurality of flame holes for gas outflow, the flame holes being arranged around the central portion, wherein the burner has at least two different operating states, the burner cap assembly being hinged to the ejector assembly to change the different operating states of the burner, and in the different operating states of the burner, the burner cap assembly having different angles relative to the horizontal plane. Thus, on the one hand, the arrangement of the flame holes around the central portion helps to evenly heat the cookware; on the other hand, the direct or indirect hinged connection between the burner cap assembly and the ejector assembly allows for flexible adjustment of the angle of the burner cap assembly relative to the horizontal plane, thereby allowing the specific position of the flame holes to be adjusted according to the different shapes and heights of the cookware used, controlling the flame angle, ensuring sufficient contact between the flame and the bottom of the pot, reducing unnecessary heat loss, and improving gas utilization.

[0006] According to an optional embodiment, the burner assembly includes M burner components, each burner component including a first section with the flame hole, the first section being constructed in a curved cylindrical shape, where M is an integer greater than one. Thus, on the one hand, the overall burner is divided into several components, allowing each component to be independently hinged and adjusted, resulting in greater flexibility; on the other hand, the curved cylindrical structure not only enhances the industrial aesthetics but also facilitates the flow of gas within the burner and makes it easier for the user to manually hold and adjust it.

[0007] According to one alternative embodiment, the central portion is integrally connected to the ejector body. This eliminates the connection interface, improves airtightness, and facilitates mass production, thereby increasing production efficiency.

[0008] According to one alternative embodiment, the central portion has a flat surface suitable for supporting the cookware. Thus, for example, for small cookware, an additional pot support can be eliminated, resulting in a simpler structure and easier use.

[0009] According to one optional embodiment, the burner includes a sensor for detecting the shape of the bottom of the cookware, and the burner cap assembly is adapted to change different operating states of the burner based on the detection results of the sensor. This facilitates precise determination of the burner's optimal operating state, enables intelligent improvements, and enhances the user experience.

[0010] According to an optional embodiment, the burner includes a detachable locking mechanism to secure the relative positions of the burner cap assembly and the ejector assembly under different operating conditions. This ensures the structural strength and stability of the burner under different operating conditions while also facilitating easy disassembly and replacement, resulting in low maintenance costs.

[0011] According to one optional embodiment, the burner includes M interface pieces that mate with M flame cap components, each interface piece communicating with both the ejector body and the corresponding flame cap component. This modular design, employing interconnected interface pieces, allows for independent manufacturing of each burner component, resulting in more flexible assembly.

[0012] According to an optional embodiment, the flame holes are located on the outer peripheral surface of the burner cap component away from the center. Thus, the flame holes are located at the outermost edge of the burner, maximizing the heating area coverage. Simultaneously, the curved column shape of the first section of the burner cap component prevents clogging of the flame holes, improving combustion efficiency and resulting in a good flame condition.

[0013] According to one alternative embodiment, each flame cap component is a one-piece molded structure. This eliminates the connection interface, resulting in better airtightness, and also facilitates mass production, improving production efficiency.

[0014] According to an optional embodiment, the curved cylindrical section is an annular segment with a central angle less than 360° / M. Thus, the central angle of each flame cap component is less than its bisector angle, and gaps are left between adjacent flame cap components, which facilitates the pivoting and swinging of each flame cap component and prevents jamming.

[0015] According to an alternative embodiment, M=4. Thus, this quartered structure can accommodate both the flexible pivoting and swinging of the flame cap components and the circumferential coverage of the flame holes.

[0016] According to an optional embodiment, each burner cap component includes a second section communicating with the first section, the second section having an air inlet, and each interface component having an air outlet cooperating with the corresponding air inlet. In different operating states of the burner, different portions of the air inlet and the corresponding air outlet are connected. This ensures that the air inlet remains connected to the corresponding air outlet despite the pivoting motion of the burner cap component in different operating states of the burner.

[0017] According to an optional embodiment, the detachable locking mechanism includes M first locking structures adapted to detachably and securely connect each burner cap component to its corresponding interface component. Thus, by disassembling and re-locking the first locking structures, the relative position of each burner cap component to its corresponding interface component can be adjusted, thereby facilitating changes in different operating states of the burner.

[0018] According to one alternative embodiment, all interface components are integrally connected to the ejector body. This eliminates the connection interface, improves airtightness, and facilitates mass production, thereby increasing production efficiency.

[0019] According to an optional embodiment, the second segment has a convex arc surface on the side facing the interface component, and the air inlet is disposed on the convex arc surface. The interface component has a corresponding concave arc surface on the side facing the second segment, and the air outlet is disposed on the concave arc surface. Thus, on the one hand, the fit between the convex and concave arc surfaces ensures good sealing, further reducing the risk of leakage; on the other hand, it also facilitates the pivoting and swinging of the flame cap component, making it less prone to jamming and significantly improving the stability and safety of the connection.

[0020] According to an optional embodiment, each first locking structure includes a first through hole on each interface member and K first blind holes on each burner cap member, as well as a first plug suitable for passing through one of the first through hole and the K first blind holes, where K corresponds to the number of operating states of the burner. Thus, by using the plug passing through one of the through hole and blind hole, the burner cap member is detachably fixed to different angular positions on the interface member, thereby achieving segmented positioning. This segmented locking structure can precisely control the angle of the burner cap member to match the shape of the cookware bottom, preventing free rotation of the burner cap member and allowing the user to manually adjust the angle as needed. The operation is simple and reliable, meeting usage requirements and facilitating mass production and maintenance.

[0021] According to one alternative embodiment, each gas outlet has a grid. Thus, the grid disperses the gas into multiple fine airflows at the gas outlet, preventing excessive gas from suddenly gushing out of one opening and affecting ignition, thereby promoting stable gas flow.

[0022] According to an optional embodiment, the second section has protrusions at its opposite ends to form pivots around which the burner cap component rotates. Thus, by having the protrusions at both ends of the second section act as pivots, the pivoting function is achieved using the burner cap component's own structure, simplifying the burner structure and increasing reliability.

[0023] According to one optional embodiment, a rotary sealing structure is provided between each air inlet and its corresponding air outlet. This prevents gas leakage even with frequent rotation and adjustment of the burner cap components, thus improving the reliability of the burner.

[0024] According to an optional embodiment, the ejector assembly includes M independent covers relative to the ejector body, each cover being connected to a corresponding interface to collectively define a receiving cavity suitable for the rotational fixation of the protrusion. Thus, the receiving cavity jointly defined by the independent covers and interface ensures reliable rotational fixation of the protrusion serving as a pivot, making the rotation of the flame cap component more stable and smooth, while also ensuring convenient and quick assembly and disassembly, and simpler daily maintenance.

[0025] According to one optional embodiment, the extension direction of the air inlet is consistent with the extension direction of the rotating shaft. This results in a uniform air pressure distribution and good flame stability at different angles.

[0026] In one optional embodiment, the extension direction of the air inlet is consistent with the arrangement direction of the grid. Therefore, the flow resistance of the gas flowing through the grid is low, resulting in high thermal efficiency.

[0027] According to an alternative embodiment, the first locking element is a bolt or a spring pin. This facilitates the implementation of a simple and reliable first locking structure.

[0028] According to an optional embodiment, the burner further includes M second locking structures suitable for detachably fixing each cover to its corresponding interface piece. Each second locking structure includes N second through holes on each cover and N second blind holes on each interface piece, as well as N second bolts adapted to pass through the second through holes and the second blind holes, respectively, where N is a positive integer. Thus, the cover and interface piece are locked using through-blind holes and bolts, resulting in a simple assembly process, precise positioning, and reliable connection.

[0029] According to one alternative embodiment, the second locking element is a bolt or a spring pin. This facilitates the implementation of a simple and reliable second locking structure.

[0030] According to one optional embodiment, N=3 and the second locking structure is arranged in a triangular pattern. This enables a stable connection between the cover and the interface component.

[0031] According to an optional embodiment, the first locking structure and the second locking structure are respectively located on opposite sides of each interface component. Thus, this opposing design separates the first locking structure for fixing the interface component to the cover and the second locking structure for fixing the interface component to the flame cap component, ensuring they do not interfere with each other and facilitating assembly operations.

[0032] According to an optional embodiment, the ejector body has a first ejector tube and a second ejector tube that are independent of each other. The diameter of the second ejector tube is larger than the diameter of the first ejector tube. The first ejector tube is connected to one of the M burner cap components, and the second ejector tube is connected to the remaining M burner cap components. Thus, the smaller diameter first ejector tube is advantageous for supplying gas to one burner cap component (equivalent to the inner burner cap of a conventional burner), facilitating rapid and concentrated ignition; while the larger diameter second ejector tube is advantageous for supplying gas to the remaining burner cap components (equivalent to the outer burner cap of a conventional burner), facilitating control of the combustion effect.

[0033] According to a second aspect of this application, a gas stove is provided, the gas stove having at least one burner for a gas stove as provided in any of the optional embodiments of the first aspect above. Thus, this gas stove particularly possesses the advantages mentioned in the above embodiments. Attached Figure Description

Detailed Implementation

[0054] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit the scope of protection of this application. Various embodiments may share the same view or multiple views for description, but not all features appearing in the same view should be interpreted as features that must be present in an embodiment.

[0055] For ease of understanding, the description provided in the background section of this application may be recalled. One object of this application is to provide a burner for a gas stove, the burner comprising: an ejector assembly having an ejector body for guiding gas, the ejector body having a vertical guide portion; a central portion communicating with the vertical guide portion; and a burner cap assembly communicating with the ejector body, the burner cap assembly having a plurality of flame holes for gas outflow, the flame holes being arranged around the central portion, wherein the burner has at least two different operating states, the burner cap assembly being hinged to the ejector assembly to change the different operating states of the burner, and in the different operating states of the burner, the burner cap assembly having different angles relative to a horizontal plane. Therefore, on the one hand, the arrangement of the flame holes around the center helps to heat the cookware evenly; on the other hand, the direct or indirect hinged connection between the flame cap assembly and the ejector assembly allows for flexible adjustment of the angle of the flame cap assembly relative to the horizontal plane. This enables the specific position of the flame holes to be adjusted according to the different shapes and heights of the cookware used, controlling the flame angle, ensuring that the flame fully contacts the bottom of the pot, reducing unnecessary heat loss, and improving gas utilization.

[0056] Exemplary embodiments of this application will now be described with reference to the accompanying drawings.

[0057] Figure 1 A schematic perspective view of a gas stove 2000 according to an exemplary embodiment of this application is shown. Figure 1 As shown, the gas stove 2000 exemplarily has two burners 1000, which will be described in detail below, and a glass plate 2001 arranged substantially horizontally. Figure 1 The diagram also schematically illustrates an xyz coordinate system, where x represents the length of the gas stove 2000, y represents the width of the gas stove 2000, and z represents the thickness or depth of the gas stove 2000. For clarity, this xyz coordinate system will be used as a basic reference in the illustrations and descriptions in the following sections.

[0058] Figure 2 It shows along Figure 1 A schematic sectional view of a section cut along the AA direction. (e.g.) Figure 2 As shown, the burner 1000 may have at least two different operating states. The methods for changing these operating states will be described in conjunction with the following specific embodiments.

[0059] Figure 3 A schematic perspective view of a burner 1000 for a gas stove 2000 according to an exemplary embodiment of this application is shown; Figure 4 It shows along Figure 3 The top view observed from direction B.

[0060] like Figure 3 and Figure 4 As shown, the burner 1000 includes an ejector assembly 900 and a flame cap assembly 800. The ejector assembly 900 has an ejector body 910 for guiding combustion gas, and the ejector body 910 has a vertical guide portion 901. The burner 1000 also includes a central portion 700 communicating with the vertical guide portion 901. The flame cap assembly 800 is directly or indirectly communicating with the ejector body 910 and has a plurality of flame holes 801 for supplying combustion gas (the accompanying drawings schematically show the main flame hole and the adjacent flame stabilizing hole). These flame holes 801 are arranged around the central portion 700. As will be discussed below... Figures 5 to 7 As described, the burner 1000 has at least two different operating states. In order to change the different operating states of the burner 1000, the burner cap assembly 800 is directly or indirectly hinged to the ejector assembly 900.

[0061] Figure 5 It shows along Figure 4 A schematic cross-sectional view of the sectioning direction CC; Figure 6 It shows along Figure 4 A schematic cross-sectional view of the sectioning direction CC in another state; Figure 7 It shows along Figure 4 A schematic cross-sectional view of a state where the sectioning direction CC is cut. Figures 5 to 7 Different shapes of pots are also illustrated with dotted lines.

[0062] Figure 5 An exemplary first operating state P1 of the burner 1000 is shown. In the first operating state P1, the burner cap assembly 800 is substantially parallel to the horizontal plane, and therefore the first operating state P1 of the burner 1000 is particularly suitable for use with a flat-bottomed pan as schematically shown by the dashed lines.

[0063] Figure 6 The second operating state P2 of the burner 1000 is illustrated by way of example. In the second operating state P2, the burner cap assembly 800 has a first included angle α1 relative to the horizontal plane, where the first included angle α1 is exemplarily 18°, so the second operating state P2 of the burner 1000 is particularly suitable for use with a wok as schematically shown by the dashed line.

[0064] Figure 7 The third operating state P3 of the burner 1000 is illustrated by way of example. In the third operating state P3, the burner cap assembly 800 has a second included angle α2 relative to the horizontal plane, where the second included angle α2 is exemplarily 36°, so the third operating state P3 of the burner 1000 is particularly suitable for a round-bottomed pan as schematically shown by the dashed lines.

[0065] from Figures 5 to 7It can be seen that by adjusting the angle of the burner cap assembly 800 relative to the horizontal plane, the position of the burner hole 801 can be made closer to the bottom of the cookware, improving thermal efficiency. At the same time, for cookware of different shapes, such as frying pans, woks, and round-bottomed pans, the angle of the burner cap assembly 800 can be adjusted to adapt to different shapes, so that the flame can be more concentrated on the bottom of the cookware, reducing heat loss.

[0066] Combination Figure 3 and Figure 4 The central portion 700 of the burner 1000 may have a flat surface suitable for supporting cookware, so that cookware of various shapes can be used even without a pot support. Figures 5 to 7 It can be placed stably on the burner 1000 as shown. In another embodiment not shown in the figures, the central portion 700 may also be configured as the central flame cap of the burner 1000.

[0067] Figure 8 A schematic exploded view of a portion of a burner 1000 according to an exemplary embodiment of this application is shown; Figure 9 It shows along Figure 8 A top view of a portion (mainly the ejector body 910 and the interface 600) observed from the direction of view D; Figure 10 It shows along Figure 9 A schematic cross-sectional view of the cutting direction FF; Figure 11 It shows along Figure 8 The front view observed from the direction of view E; Figure 12 It shows along Figure 11 A schematic cross-sectional view of the sectioning direction GG; Figure 13 It shows along Figure 11 A schematic cross-sectional view of the sectioning direction HH; Figure 14 A schematic perspective view of a flame arrestor component 810 according to an exemplary embodiment of this application is shown; Figure 15 It shows along Figure 14 A top view observed from the direction of J; Figure 16 It shows along Figure 14 The front view observed from the direction of L; Figure 17 It shows along Figure 16 A schematic cross-sectional view of the sectioning direction QQ.

[0068] Combination Figure 3 and Figure 4 As shown, the flame cap assembly 800 includes M flame cap components 810, each flame cap component 810 (also as...) Figures 14 to 17(As shown) includes a first section 100 with flame holes 801, the first section 100 being constructed in a curved cylindrical shape, where M is an integer greater than one. In the embodiment shown in the figures, M = 4. In embodiments not shown in the figures, M may also be other integers greater than one to accommodate burner size and adjustment settings. These flame cap components 810 are preferably constructed rotationally symmetrically about the central portion 700 and are each a single-piece structure, particularly preferably made of copper. Figure 15 Combination Figure 3 It can be seen that the flame hole 801 is located on the outer peripheral surface of the flame cap component 810, away from the center portion 700. From Figure 15 It can also be seen that the first segment 100 of the curved column is constructed as an annular segment with a central angle β less than 360° / M. In the embodiment of Figure M=4, the central angle β is exemplarily 87°.

[0069] like Figure 14 and Figure 17 As shown, each burner cap component 810 also includes a second section 200 communicating with the first section 100, and each second section 200 has an air inlet 201. To communicate each burner cap component 810 with the ejector body 910 of the ejector assembly 900, the burner 1000 also includes M interface members 600 (i.e., four interface members 600 in the embodiment shown in the figures). Figure 8 As shown, each interface member 600 has an outlet 601 for engaging with a corresponding inlet 201 of the second segment 200 of each flame header member 810. Preferably, all interface members 600 are integrally connected to the ejector body 910. In this case, the interface member 600 provides a fixed outlet 601, and the corresponding inlet 201 communicates with different locations of the outlet 601 (e.g., in the vertical or height y direction) as the flame header member 810 pivots relative to the ejector body 910. Figure 14 Combination Figure 8 As shown, the second segment 200 has a convex arc surface on the side facing the interface member 600, and the air inlet 201 is disposed on this convex arc surface; correspondingly, the interface member 600 has a corresponding concave arc surface on the side facing the second segment 200, and the air outlet 601 is disposed on the concave arc surface. Thus, the air inlet 201 and the air outlet 601 can form flow-guiding connections at different positions depending on the different mating states between the convex arc surface of the second segment 200 and the concave arc surface of the interface member 600. Preferably, a rotary sealing structure is provided between each air inlet 201 and each corresponding air outlet 601. Optionally, each air outlet 601 is as follows... Figure 8 The diagram shows a grid, which is preferably arranged horizontally, and the corresponding air intake 201 extends in the same direction as the grid, that is, it also preferably extends horizontally (as shown). Figure 14(As shown). To facilitate the pivoting of each flame cap component 810 relative to the ejector body 910 of the ejector assembly 900, from Figures 14 to 17 It can be clearly seen that the second segment 200 of each flame cap member 810 has protrusions 202 at opposite ends to form a pivot about which the flame cap member 810 rotates. The extension direction of the air inlet 201 of the second segment 200 of each flame cap member 810 is preferably consistent with the extension direction of the pivot, that is, preferably extends horizontally (as shown in the image). Figure 14 (As shown).

[0070] from Figure 8 Combination Figures 5 to 7 It can also be seen that the burner 1000 includes a detachable locking mechanism to secure the relative positions of the burner cap assembly 800 and the ejector assembly 900 in different operating states. Specifically, this detachable locking mechanism may include M first locking structures 10 (i.e., four first locking structures 10 in the embodiment shown in the figures) suitable for detachably securing each burner cap component 810 to its corresponding interface member 600. Figure 14 Each first locking structure 10 may include a first through hole 11 on each interface member 600 and K first blind holes 12 on each burner cap member 810, and a first plug 13 passing through one of the first through hole 11 and the K first blind holes 12, where K is an integer greater than one and corresponds to the number of operating states of the burner 1000. The burner 1000 may have, for example, a... Figures 5 to 7 In the three operating states shown, K = 3. When the burner 1000 has other operating states, K can be changed accordingly. When the first blind hole 12 is a threaded hole, the first bolt 13 can be constructed, for example, as a bolt; when the first blind hole 12 is a smooth hole, the first bolt 13 can be constructed, for example, as a spring pin. Combined with... Figure 14 The three first blind holes 12 are, in a counterclockwise direction, first blind hole 12a, first blind hole 12b, and first blind hole 12c. When the first plug 13 passes through the first through hole 11 on the interface piece 600 and is fixed in the first blind hole 12a, the burner 1000 can be locked, for example. Figure 5 In the first operating state P1 shown; when the first plug 13 passes through the first through hole 11 on the interface piece 600 and is fixed in the first blind hole 12b, the burner 1000 can be locked, for example. Figure 6 In the second operating state P2 shown; when the first plug 13 passes through the first through hole 11 on the interface piece 600 and is fixed in the first blind hole 12c, the burner 1000 can be locked, for example. Figure 7 In the third working state P3 shown.

[0071] from Figure 8 Combination Figure 3As can be seen, the ejector assembly 900 also includes M independent covers 930 relative to the ejector body 910 (i.e., four covers 930 in the embodiment shown in the figures, but...). Figure 8 (Only one cover 930 is shown schematically.) Each cover 930 is connected to a corresponding interface 600 to collectively define a receiving cavity 902 suitable for rotating and fixing the protrusion 202 of the second section 200 of each fire cap member 810.

[0072] from Figure 8 It can also be seen that the burner 1000 further includes M second locking structures 20 (i.e., four second locking structures 20 in the embodiment shown in the figures) suitable for detachably fixing each cover 930 to the corresponding interface 600. Each second locking structure 20 may specifically include N second through holes 21 provided on each cover 930 and N second blind holes 22 provided on each interface 600, and N second pins 23 respectively passing through the second through holes 21 and the second blind holes 22, where N is a positive integer. In the embodiment shown in the figures, N=3 and the second locking structures 20 are preferably arranged in a triangular pattern as shown. In embodiments not shown in the figures, N may also be other positive integers to reduce manufacturing costs or to further improve connection strength. When the second blind hole 22 is a threaded hole, the second pin 23 may be constructed as a bolt, for example; when the second blind hole 22 is a smooth hole, the second pin 23 may be constructed as a spring pin, for example. Preferably, as shown in the figures... Figure 8 Combination Figure 14 As shown, the detachable first locking structure 10 and the detachable second locking structure 20 are located on opposite sides of each interface piece 600.

[0073] from Figures 9 to 13 Combination Figure 8 It can be seen that the ejector body 910 itself is preferably a one-piece structure made of, for example, aluminum, and the central portion 700 and all interface parts 600 are also preferably integrally connected to the ejector body 910. The ejector body 910, as... Figure 9 and Figure 12 The diagram shows a first ejector tube 911 and a second ejector tube 912 that are independent of each other. The first ejector tube 911, which has a small diameter, is connected to one of the flame cap components 810 (e.g., Figure 13 As exemplarily shown, it is connected to the right flame cap component 810 among the four flame cap components 810 via a corresponding interface 600, enabling it to function as the center flame cap or inner flame cap in a conventional burner; while the large-diameter second ejector tube 912 is connected to the other flame cap components 810 (e.g., ...). Figure 13 As exemplarily shown, it is connected to three flame cap components 810 on the upper, left and lower sides respectively through corresponding interface components 600, so that it can play the role of the outer flame cap in a conventional burner.

[0074] Referring to the embodiments shown in the accompanying drawings, an exemplary assembly method of the burner 1000 is described here: First, each burner cap component 810 is positioned on the corresponding interface member 600 to ensure that the protrusion 202 of each second segment 200 is received in the corresponding receiving cavity 902. Then, each cap 930 is positioned on the corresponding interface member 600. Finally, each cap 930 is locked to the corresponding interface member 600 by each second locking structure 20 (i.e., by inserting each second bolt 23 through the second through hole 21 and the second blind hole 22). After assembly, for example, the burner 1000 needs to be set to the most commonly used first operating state P1 (e.g., ...). Figure 5 When (as shown), each first plug 13 is fixed to each first blind hole 12a via the first through hole 11 on each interface member 600 to lock the burner 1000 in the first operating state P1. Referring again to the embodiment shown in the accompanying drawings, the burner 1000 is described here, for example, from... Figure 5 The first working state P1 shown is transformed as follows: Figure 6 An exemplary method of operation for the second operating state P2 shown is as follows: First, each first locking structure 10 is unlocked, for example, by removing each first plug 13 from each first blind hole 12a via each first through hole 11, to allow the burner cap assembly 810 to pivot relative to the interface member 600; then, each burner cap assembly 810 is rotated and each first plug 13 is secured to each first blind hole 12b via the first through hole 11 on each interface member 600, to lock the burner 1000 in the second operating state P2. In a preferred embodiment, the burner 1000 may further include a sensor for detecting the shape of the bottom of the cookware, and the burner cap assembly 800 is adapted to change different operating states of the burner 1000 based on the detection results of the sensor. In an embodiment not shown in the figures, the switching of the burner 1000 between different operating states may also be achieved automatically by electric or hydraulic means.
