Description

Technical Field

[0001] The present invention belongs to the technical field of kitchen stoves, and particularly relates to a burner, and also relates to a gas stove equipped with the burner. Background Art

[0002] As a commonly used cooking tool in daily life, people's requirements for the hygiene and cleaning of gas stoves are gradually increasing.

[0003] A gas stove generally has a panel, a burner head, a combustion structure and a pot support arranged above the panel. The combustion structure is composed of a burner cap seat and a burner cap. During use, the panel under the burner cap seat and the pot support is often not cleaned. Especially for a gas stove with upward air intake, the gap between the burner cap seat and the panel is small, and cleaning tools cannot be inserted into it, forming a hygiene dead corner.

[0004] To solve this problem, a Chinese invention patent with the application number CN201811230937.2 discloses a two-ring fire gas stove with a rotatable burner, which fixes the sub-fire divider seat, the center burner cap, the outer ring burner cap, the pot support and the support rotating seat as a whole. A fixed pivot seat is fixed on the panel, and the support rotating seat is rotationally matched with the fixed pivot seat through a rotating seat, so that the burner composed of the sub-fire divider seat, the center burner cap, the outer ring burner cap, the pot support and the support rotating seat can rotate relative to the panel.

[0005] Although this solution can clean the panel under the pot support and the sub-fire divider seat, it will form a complicated installation structure on the panel. Especially after long-term use, a stubborn cleaning dead corner will form at the fixed pivot seat located at the rear of the burner, and this cleaning dead corner will be directly exposed to the user's sight, affecting the user experience. At the same time, this solution needs to fix the center burner cap and the outer ring burner cap on the sub-fire divider seat, and a fixing structure needs to be added between the center burner cap, the outer ring burner cap and the sub-fire divider seat, which increases the production cost and the difficulty of disassembly and assembly.

[0006] In view of this, the present invention is specifically proposed. Summary of the Invention

[0053] It should be noted that these drawings and text descriptions are not intended to limit the scope of the concept of the present invention in any way, but to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0054] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0055] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0056] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] In the prior art, most gas stoves are equipped with a drip tray. On the one hand, the drip tray with uneven shapes will increase the difficulty of cleaning the stove top; on the other hand, the addition of the drip tray will greatly increase the manufacturing cost of the gas stove.

[0058] To solve this technical problem, an embodiment of the present invention provides a gas stove, specifically, an up-draft gas stove without a drip tray, as Figures 1 to 11 shown.

[0059] Embodiment 1

[0060] As Figures 1 to 10 shown, in an embodiment of the present invention, a burner is introduced. The burner includes a burner head 4 and a main body. A gas injection structure 43 is provided at the top of the burner head 4, and the main body is detachably installed on the top of the gas injection structure 43.

[0061] In this embodiment, the main body includes a combustion structure and a wok support 3 that are connected to each other.

[0062] In this embodiment, only the necessary gas injection structure 43 is used to support the main body to realize the installation of the main body, which is beneficial to simplifying the structure on the panel 1 of the gas stove and making the gas stove more concise. At the same time, the main body can be detached from the top of the gas injection structure 43 as a whole. Thus, when the user needs to clean the panel 1, the main body can be detached from the top of the gas injection structure 43 to expose the panel 1 directly below the main body, which is convenient for the user to clean and avoids the formation of sanitary dead corners on the panel 1 under the combustion structure and the wok support 3, improving the user experience. In addition, there is no need to set a fixing structure between the burner cap seat 2 and the burner cap of the combustion structure, which can simplify the structure of the burner and is beneficial to reducing the production cost of the gas stove.

[0063] In this embodiment, the gas injection structure 43 is arranged below the combustion structure. Preferably, it is arranged directly below the combustion structure to support the main body from the bottom of the combustion structure. The gas injection port of the gas injection structure 43 is arranged on the side of the gas injection structure 43 and corresponds to the air inlet end of the ejector pipe at the bottom of the combustion structure. By arranging the gas injection structure 43 below the combustion structure, the support stability of the main body can be ensured. Moreover, the gas injection structure 43 can be shielded by the pot support 3, further improving the simplicity and aesthetics of the appearance of the gas stove.

[0064] In this embodiment, one or more gas injection structures 43 are provided.

[0065] In some possible embodiments, one gas injection structure 43 is provided. A supporting portion that fits the bottom of the combustion structure is arranged at the top of the gas injection structure 43. The supporting portion is sheet-shaped and extends along the bottom of the combustion structure, and can stably support the combustion structure thereon, ensuring the installation stability of the main body.

[0066] In some other possible embodiments, a plurality of gas injection structures 43 are provided. The plurality of gas injection structures 43 are arranged at intervals along the circumferential direction of the combustion structure and support the bottom of the combustion structure from multiple directions, ensuring the support stability of the main body.

[0067] Preferably, the plurality of gas injection structures 43 are arranged close to the bottom edge of the combustion structure, which can further improve the support stability of the main body and prevent the pot from tipping over.

[0068] In this embodiment, the gas injection port of the gas injection structure 43 corresponds to the air inlet end of the ejector pipe at the bottom of the combustion structure. Preferably, the gas injection port is coaxial with the ejector pipe.

[0069] In this embodiment, the number of ejector pipes at the bottom of the combustion structure is greater than or equal to the number of gas injection structures 43. Specifically, when the number of ejector pipes is equal to the number of gas injection structures 43, a single gas injection mechanism has only one gas injection port, corresponding to the air inlet end of the ejector pipe; when the number of ejector pipes is greater than the number of gas injection structures 43, at least one gas injection structure 43 has a plurality of gas injection ports respectively corresponding to a plurality of ejector pipes.

[0070] In this embodiment, one gas injection structure 43 has at least one gas injection port.

[0071] Preferably, in this embodiment, a plurality of ejector pipes are arranged at the bottom of the combustion structure, and a plurality of gas injection structures 43 corresponding one by one to the ejector pipes at the bottom of the combustion structure are provided. Each gas injection structure 43 has one gas injection port.

[0072] In some preferred embodiments, at least three of the gas injection structures 43 are provided.

[0073] In this embodiment, the combustion structure includes an inner ring mixing chamber 21 and an outer ring mixing chamber 22. The ejector tube includes a first ejector tube 23 communicating with the inner ring mixing chamber 21 and a second ejector tube 24 communicating with the outer ring mixing chamber 22. The air inlet ends of the first ejector tube 23 and the second ejector tube 24 are both arranged near the outer periphery of the outer ring mixing chamber 22. The gas injection structures 43 corresponding to the air inlet ends of the first ejector tube 23 and the second ejector tube 24 are both arranged directly below the outer ring mixing chamber 22. That is, the gas injection structures 43 support the combustion structure from the bottom of the outer ring mixing chamber 22.

[0074] Specifically, in this embodiment, the combustion structure includes a burner base 2, an inner burner cap 211 and an outer burner cap 221. The burner base 2 includes an inner ring mixing chamber 21 and an outer ring mixing chamber 22. The outer ring mixing chamber 22 is arranged around the inner ring mixing chamber 21, and there is an interval between the outer periphery of the inner ring mixing chamber 21 and the inner periphery of the inner ring mixing chamber 21. The inner burner cap 211 and the outer burner cap 221 are respectively buckled on the top of the inner ring mixing chamber 21 and the top of the outer ring mixing chamber 22, and the gas-air mixture burns on the inner burner cap 211 and the outer burner cap 221.

[0075] In this embodiment, the burner base 2 is disc-shaped, and three gas injection structures 43 are provided. Horizontally, these three gas injection structures 43 will not be in the same semi-circular area of the disc-shaped burner base 2 at the same time, so as to achieve stable support for the burner base 2.

[0076] Specifically, the three gas injection structures 43 are distributed at different positions of the burner base 2. The maximum arc length corresponding to any two gas injection structures 43 does not exceed a semi-circle. That is, the central angle formed by the connecting lines of any two gas injection structures 43 and the center of the burner base 2 is less than 180 degrees, thus forming a stable triangular support structure. This distribution does not require the gas injection structures 43 to be evenly arranged, but ensures the support stability of the burner base 2.

[0077] Preferably, the distances from the gas injection structures 43 to the center of the burner base 2 can be the same or different.

[0078] Preferably, in this embodiment, two second ejector tubes 24 are provided and are arranged on opposite sides of the outer ring mixing chamber 22; the air inlet ends of the two second ejector tubes 24 face the same direction, and the air inlet end of the first ejector tube 23 faces the opposite direction to the air inlet ends of the second ejector tubes 24; or the air inlet ends of the two second ejector tubes 24 face opposite directions. Thus, it can be avoided that the air inlet ends of the two second ejector tubes 24 and one first ejector tube 23 are concentrated on the same side of the combustion structure, ensuring the support stability of the combustion structure.

[0079] Preferably, the first ejector tube 23 and the second ejector tube 24 extend tangentially along the inner-ring mixing chamber 21 and the outer-ring mixing chamber 22 respectively. In this embodiment, the statement that "the first ejector tube 23 extends tangentially along the inner-ring mixing chamber 21" specifically means that the extending direction of the first ejector tube 23 is consistent with the extending direction of a tangent line of the inner-ring mixing chamber 21; the statement that "the second ejector tube 24 extends tangentially along the outer-ring mixing chamber 22" specifically means that the extending direction of the second ejector tube 24 is consistent with the extending direction of a tangent line of the outer-ring mixing chamber 22.

[0080] Preferably, in this embodiment, the first ejector tube 23 and the second ejector tube 24 are parallel to each other.

[0081] Preferably, as Figure 9 shown, in this embodiment, the air inlet ends of the two second ejector tubes 24 face in opposite directions, and the first ejector tube 23 and the second ejector tube 24 are parallel to each other. Among them, the first ejector tube 23 is arranged close to one of the second ejector tubes 24 with the same orientation as it.

[0082] Specifically, the air inlet end of one second ejector tube 24 faces the first direction, and the air inlet end of the other second ejector tube 24 faces the second direction, and the first direction is opposite to the second direction. The air inlet end of the first ejector tube 23 faces the first direction, and the first ejector tube 23 is arranged close to the second ejector tube 24 with the air inlet end facing the first direction.

[0083] In some specific embodiments, the air outlet end of the second ejector tube 24 extends circumferentially along the outer-ring mixing chamber 22, and along the direction away from the air inlet end of the second ejector tube 24, the bottom of the air outlet end of the second ejector tube 24 gradually rises, so that the guiding effect on the mixture of gas and primary air can be improved.

[0084] In this embodiment, by setting the air inlet ends of the two second ejector tubes 24 to face in opposite directions, the mixture of gas and primary air can spiral upward in the outer-ring mixing chamber 22, improving the smoothness of guiding the mixture, ensuring the ejecting effect on the primary air, and moreover, improving the uniformity of the mixture of gas and primary air and the combustion effect of the gas.

[0085] By arranging the first ejector tube 23 close to one of the second ejector tubes 24 with the same orientation as it, it can ensure that there is enough space between the air outlet end of the second ejector tube 24 with the air inlet end facing the second direction and the air inlet end of the first ejector tube 23 to layout the gas injection structure 43, avoiding interference between the air inlet end of the first ejector tube 23 and the air outlet end of the second ejector tube 24.

[0086] Preferably, in this embodiment, a nozzle 431 is installed at the gas injection port of the gas injection structure 43, and the nozzle 431 is coaxial with the air inlet end of the ejector tube.

[0087] In this embodiment, a circumferential positioning structure is provided between the burner head 4 and the main body portion. The circumferential positioning structure is used to improve the installation accuracy of the main body portion, ensure that the air inlet end of the ejector tube corresponds to the gas injection port of the gas injection structure 43 one by one, and enable the burner to work stably.

[0088] In some possible embodiments, a magnetic connection is provided between the top of the gas injection structure 43 and the bottom of the main body portion. Specifically, a magnetic block is embedded in the top of the gas injection structure 43, and at least the part of the bottom of the outer ring mixing chamber 22 corresponding to the gas injection structure 43 is made of ferromagnetic material.

[0089] In some possible embodiments, a groove corresponding to the top of the gas injection structure 43 is provided at the bottom of the main body portion, and the top of the gas injection structure 43 is embedded in the groove.

[0090] Specifically, a groove is provided at the bottom of the outer ring mixing chamber 22, and the top of the gas injection structure 43 is inserted into the groove to achieve circumferential positioning of the main body portion. Preferably, three gas injection structures 43 are provided, and the tops of the three gas injection structures 43 all correspond to the bottom of the outer ring mixing chamber 22. The three gas injection structures 43 are arranged unevenly in the circumferential direction of the combustion structure. Specifically, the intervals between adjacent two gas injection structures 43 are different. Thus, during the installation process of the combustion structure, the installation angle error of the combustion structure on the burner head 4 can be avoided.

[0091] In some preferred embodiments, a protruding installation portion extending upward is provided on the burner head 4, and a positioning portion cooperating with the installation portion is provided on the main body portion. Through the cooperation between the positioning portion and the installation portion, circumferential positioning of the combustion structure is achieved.

[0092] In this embodiment, along the installation direction of the main body portion, the positioning portion and the installation portion are sleeved and cooperated.

[0095] Preferably, the installation part includes the ignition needle 41 and / or the thermocouple 42. The positioning part extends radially along the main body part and is sleeved on the periphery of the ignition needle 41 and / or the thermocouple 42 through the positioning groove; and / or, the installation part includes a columnar protrusion 26. The positioning part extends axially along the main body part and is sleeved on the top of the columnar protrusion 26 through the positioning groove.

[0096] In this embodiment, the ignition needle 41 is installed on the burner head 4 through the ignition needle sleeve 44.

[0097] In some preferred embodiments, multiple sets of the installation part and the positioning part are provided and cooperate with each other.

[0098] In some possible embodiments, the installation part includes the ignition needle 41 and / or the thermocouple 42. The positioning part includes a first positioning part 251. The first positioning part 251 is a plate-shaped part extending radially along the main body part. A first positioning groove 252 for sleeving on the outer periphery of the ignition needle 41 and / or the thermocouple 42 is provided on the first positioning part 251.

[0099] Preferably, as Figures 1 to 9 shown, the ignition needle 41 and the thermocouple 42 are provided on the burner head 4, and the ignition needle 41 and the thermocouple 42 correspond to the interval between the inner ring mixing chamber 21 and the outer ring mixing chamber 22.

[0100] The first positioning part 251 is plate-shaped and extends radially along the main body part, and at least partially extends between the inner ring mixing chamber 21 and the outer ring mixing chamber 22. A first positioning groove 252 is provided on the first positioning part 251, and the first positioning groove 252 is sleeved on the outer peripheral wall of the ignition needle 41 and / or the thermocouple 42.

[0101] Preferably, in this embodiment, the ignition needle 41 and the thermocouple 42 are close to each other. There is one first positioning groove 252, which is arranged around the ignition needle 41 and the thermocouple 42, and includes a first recess corresponding to the ignition needle 41 and a second recess corresponding to the thermocouple 42. The ignition needle 41 and the thermocouple 42 are cooperated with through one first positioning groove 252.

[0102] In some preferred embodiments, a protective cover 27 extending outward is provided on the outer peripheral wall of the inner fire cover 211, or a protective cover 27 extending inward is provided on the inner peripheral wall of the outer fire cover 221.

[0114] As Figure 1 shown, in the embodiment of the present invention, a gas stove is further provided. The gas stove includes the above-mentioned burner, the panel 1 and the housing 10.

[0115] The panel 1 is installed on the top of the housing 10, and a cavity is formed between the panel 1 and the housing 10. The burner head 4 is installed in the cavity. Specifically, the burner head 4 is installed at the bottom of the housing 10 and is fixedly connected to the housing 10 through connection structures such as screws, bolts, and buckles.

[0116] In this embodiment, the burner head 4 mainly consists of a gas injection structure 43, a gas distribution pipe, and a bracket. The gas distribution pipe is used to transport gas from the gas valve to the gas injection structure 43. The gas distribution pipe and the gas injection structure 43 are both fixed on the bracket, and the bracket is fixedly connected to the housing 10.

[0117] An installation opening 12 is provided on the panel 1. The burner head 4 is installed below the panel 1. The gas injection structure 43 at the top of the burner head 4 extends upward through the installation opening 12 on the panel 1, and the top of the gas injection structure 43 extends above the panel 1. The main body is installed on the gas injection structure 43 and is disposed opposite to the panel 1. Thus, it is beneficial to reduce the size of the installation opening 12 provided on the panel 1 and improve the aesthetics of the panel 1.

[0118] As Figure 6 shown, in this embodiment, two installation openings 12 are provided on the panel 1. Among them, the gas injection structure 43 corresponding to the air inlet end of the first ejector tube 23 and the gas injection structure 43 corresponding to the air inlet end of the second ejector tube 24 with the air inlet end facing the first direction are arranged in the same installation opening 12, and the gas injection structure 43 corresponding to the air inlet end of the ejector tube with the air inlet end facing the second direction is arranged in the other installation opening 12.

[0119] Preferably, in this embodiment, the thermocouple 42 and the ignition pin 41 are arranged in one of the installation openings 12, and the columnar protrusion 26 is arranged in the other installation opening 12.

[0121] In this embodiment, a decorative cover 11 for shielding the mounting opening 12 is installed at the mounting opening 12. A first opening 111 adapted to the outer peripheral shape of the gas injection structure 43 and a second opening 112 adapted to the outer peripheral shape of the mounting portion are formed on the decorative cover 11.

[0122] Preferably, in this embodiment, the decorative cover 11 includes a plate portion covering the mounting opening 12 and fitting with the panel 1, and a cylindrical portion vertically extending downward from the middle of the plate portion and having an outer periphery fitting with the inner wall of the mounting opening 12. The first opening 111 and / or the second opening 112 is / are provided in the middle of the plate portion.

[0123] In some possible embodiments, the columnar protrusion 26 is also used for positioning the decorative cover 11. Specifically, the lower end of the columnar protrusion 26 passes through the second opening 112 and is detachably connected to the burner head 4. The portion of the columnar protrusion 26 located above the decorative cover 11 fits with the top of the decorative cover 11 on the outer periphery of the second opening 112. Thus, the decorative cover 11 can be limited on the panel without setting additional mounting structures such as screws.

[0124] Preferably, the lower end of the columnar protrusion 26 is threadedly connected to the burner head.

[0125] Preferably, the upper end of the columnar protrusion 26 fits with the bottom of the burner cap seat 2, that is, the columnar protrusion can also support the burner cap seat, further improving the mounting stability of the burner cap seat.

[0126] In this embodiment, the pot support 3 includes a support ring 31 arranged around the combustion structure. The support ring 31 is arranged on the outer periphery of the burner cap seat 2. The inner diameter of the support ring 31 is the same as the outer diameter of the burner cap seat 2, or the inner diameter of the support ring 31 is slightly larger than the outer diameter of the burner cap seat 2. The support ring 31 extends in a direction away from the axis of the burner cap seat 2.

[0127] Preferably, the outer diameter of the support ring 31 is greater than or equal to the maximum distance between the edge of the mounting opening 12 and the axis of the burner cap seat 2, that is, the projection of the outer edge of the support ring 31 on the panel 1 surrounds outside the mounting opening 12. Thus, the whole formed by the pot support 3 and the burner cap seat 2 can shield the mounting opening 12 on the panel 1, further improving the aesthetics of the gas stove.

[0128] Preferably, the outer diameter of the support ring 31 is greater than or equal to the maximum distance between the edge of the decorative cover 11 and the axis of the burner base 2, so that the decorative cover 11 will not be exposed, or only a small part of the decorative cover 11 will be exposed from the gap between the inner ring mixing chamber 21 and the outer ring mixing chamber 22, improving the user's visual experience.

[0129] Preferably, in this embodiment, along the direction away from the axis of the burner base 2, the support ring 31 extends obliquely downward, and / or the outer periphery of the support ring 31 extends vertically downward, which can further enhance the shielding effect of the support ring 31 on the decorative cover 11 and prevent the user from directly observing the decorative cover 11 from the side of the pot support 3.

[0130] Through the above settings, the outer edge of the support ring 31 can extend to the outer periphery of the decorative cover 11, and the outer edge of the support ring 31 is close to the panel 1. Thus, the user can be prevented from directly observing the decorative cover 11 from the obliquely front of the gas stove, improving the user's visual experience. In addition, under the supporting action of the burner base 2 on the pot support 3, the outer edge of the support ring 31 is spaced from the panel 1, so that the primary air inhaled through the ejector tube during the gas injection process and part of the secondary air required during the gas combustion process can enter through the gap between the support ring 31 and the panel 1, ensuring the combustion effect.

[0131] In some preferred embodiments, along the direction away from the axis of the burner base 2, the support ring 31 has a first extension section 312 that extends obliquely upward along the direction away from the axis of the burner base 2, and a second extension section 313 that extends vertically downward from the outer edge of the support ring 31. The setting of the first extension section 312 is conducive to the heat of the flame combustion converging towards the bottom of the cookware, improving the utilization rate of heat. At the same time, the setting of the second extension section 313 can also ensure the shielding effect on the decorative cover 11 and ensure the aesthetics.

[0132] In this embodiment, the pot support 3 is coaxial with the burner base 2, and the axis of the burner base 2 is the axis of the pot support 3, which is the axis of the support ring 31 and the axis of the combustion structure.

[0133] In this embodiment, a first support leg 32 is provided on the support ring 31, and the first support leg 32 is provided at the top of the support ring 31. The pot support 3 supports the cookware through the first support leg 32.

[0134] In this embodiment, a plurality of first support legs 32 are provided and arranged uniformly along the circumferential direction of the support ring 31 to ensure the support stability of the cookware. Preferably, four first support legs 32 are provided, and the four first support legs 32 are arranged uniformly along the circumferential direction of the support ring 31.

[0135] In some specific embodiments, the first foot 32 is plate-shaped and extends radially along the support ring 31. A support portion extending towards the axis of the support ring 31 is provided at the top thereof, and the top of the support portion is provided with an inclined surface extending downwardly in a direction close to the axis of the support ring 31.

[0136] In some possible embodiments, no second foot is provided below the support ring 31, or a second foot is provided below the support ring and is hidden by the support ring. Specifically, when the user is using it normally, the second foot is not visible, making the pot support form a suspended effect and improving the user's visual experience.

[0137] In some other possible embodiments, a second foot 33 is provided at the bottom of the support ring 31, and the bottom of the second foot 33 is close to the panel 1 of the gas stove.

[0138] Specifically, the second foot 33 can assist the burner base 2 in supporting the support ring 31. When the weight of the cookware supported on the pot support 3 is relatively large, the support ring 31 will deform, enabling the panel 1 to provide a support force to the support ring 31 through the second foot 33, improving the support stability of the pot support 3 for the cookware.

[0139] Preferably, the bottom of the second foot 33 is in contact with the panel 1 of the gas stove, and when no cookware is placed on the pot support 3, the second foot 33 does not exert pressure on the panel 1, or there is a gap between the bottom of the second foot 33 and the panel 1 of the gas stove.

[0140] Through the above arrangement, when no cookware is placed on the pot support 3, or when the cookware supported on the pot support 3 is relatively light, the bottom of the second foot 33 will not exert pressure on the panel 1 and will not even come into contact with the panel 1, which can avoid the situation that obvious indentations appear on the panel 1 due to the long-term extrusion of the second foot 33 on the panel 1. At the same time, the setting of the second foot 33 can further prevent the cookware supported on the pot support 3 from tipping over and improve the stability of the gas stove during operation.

[0141] Preferably, in this embodiment, there is a gap between the bottom of the second foot 33 and the panel 1 of the gas stove.

[0142] In this embodiment, the second foot 33 is plate-shaped and extends radially along the support ring 31.

[0143] Preferably, in this embodiment, a plurality of second feet 33 corresponding to the first feet 32 one by one are provided.

[0144] Preferably, the second foot 33 and the first foot 32 are integral parts formed on the support ring 31.

[0145] Preferably, in this embodiment, a U-shaped member 34 is provided at the bottom of the second leg 33. The U-shaped member 34 is made of a flexible material and is fixed to the bottom of the second leg 33, covering the bottom of the second leg 33 therein. The bottom of the second leg 33 contacts the panel 1 through the U-shaped member 34, which can prevent the bottom of the second leg 33 from scratching the panel 1 when contacting the panel 1.

[0146] In this embodiment, the U-shaped member 34 can be made of silicone material or heat-resistant rubber material.

[0147] Preferably, in this embodiment, the bottom of the second leg 33 is lower than the bottom of the burner base 2. Thus, after the user removes the burner base 2 and the pot support 3 and places them, the second leg 33 can support the whole formed by the burner base 2 and the pot support 3, so that the whole formed by the burner base 2 and the pot support 3 can be kept stable, and it can prevent the bottom of the burner base 2 from contacting the support surface for placing the burner base 2 and the pot support 3, avoiding dirt from entering the injection pipe.
