Description

Technical Field

[0001] The present invention belongs to the technical field of kitchen cookers, 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] Chinese invention patent with application number CN201811230937.2 discloses a two-ring fire gas stove with a rotatable burner, which fixes a fire divider seat, a central fire cover, an outer ring fire cover, a pot support and a 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 can rotate relative to the panel.

[0004] In this solution, the mutually cooperating rotating seat and fixed pivot seat will make the appearance of the burner form an irregular shape. At the same time, after long-term use, stubborn cleaning dead corners will form at the fixed pivot seat located at the rear side of the burner, and this cleaning dead corner will be directly exposed to the user's sight, affecting the user experience.

[0005] However, this solution requires the rotating seat and the fixed pivot seat to ensure the stable installation of the fire cover seat. If the rotating seat and the fixed pivot seat are cancelled, the installation stability of the fire cover seat will become worse.

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

[0042] It should be noted that these drawings and textual 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 reference to specific embodiments. Detailed implementation manners

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention 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.

[0044] In the description of the present invention, it should be noted that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are 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 thus should not be construed as a limitation to the present invention.

[0045] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" 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.

[0046] In the prior art, most gas stoves are equipped with a liquid storage tray. On the one hand, the liquid storage tray with uneven shapes will increase the difficulty of cleaning the stove surface; on the other hand, the addition of the liquid storage tray greatly increases the manufacturing cost of the gas stove.

[0047] To solve this technical problem, an embodiment of the present invention provides a gas stove, specifically, an upward air intake gas stove without a liquid storage tray, as Figures 1 to 10 shown.

[0048] Embodiment 1

[0049] As Figures 1 to 9 shown, in the embodiment of the present invention, the burner is introduced. The burner includes a burner head 4 and a burner cap seat 2. A gas injection structure 43 for injecting gas into the injection pipe of the burner cap seat 2 is provided on the burner head 4.

[0050] A plurality of the gas injection structures 43 are provided. The burner cap seat 2 is installed on the top of the burner head 4 through a plurality of gas injection structures 43. A positioning structure 200 is provided between the top of at least one gas injection structure 43 and the bottom of the burner cap seat 2. By providing the positioning structure 200 between the top of the gas injection structure 43 and the bottom of the burner cap seat 2, relative movement between the burner cap seat 2 and the gas injection structure 43 can be avoided during use, so that the gas injection port of the gas injection structure 43 and the air inlet end of the injection pipe are always kept aligned, ensuring the stability of the primary air injection and improving the working stability of the burner.

[0051] In this embodiment, only the necessary gas injection structures 43 are used to support the burner cap seat 2, simplifying the installation structure of the burner cap seat 2, facilitating the user to clean the panel 1 below the burner cap seat 2, and enabling the appearance of the burner to be more regular and beautiful.

[0052] When the user needs to clean the panel 1, the burner cap seat 2 together with the burner cap thereon can be detached from the top of the gas injection structure 43. There is no need to provide a fixing structure between the burner cap seat 2 and the burner cap, simplifying the structure of the burner and being beneficial to reducing the production cost of the gas stove.

[0053] In this embodiment, the gas injection structure 43 is columnar, the burner cap seat 2 is disc-shaped, and the positioning structure 200 includes a plugging structure and / or a suction structure provided between the bottom of the burner cap seat 2 and the top of the gas injection structure 43.

[0054] In some possible embodiments, the plug-in structure includes a plug-in groove and a plug-in projection 201 disposed between the top of the gas injection structure 43 and the bottom of the burner base 2, and the plug-in grooves and the plug-in projections 201 correspond to each other one by one. Specifically, the plug-in grooves are provided at the bottom of the burner base 2 and correspond to the plug-in projections 201 provided at the top of the gas injection structure 43 one by one, and / or the plug-in projections 201 are provided at the bottom of the burner base 2 and correspond to the plug-in grooves provided at the top of the gas injection structure 43 one by one.

[0055] Preferably, as Figure 8 shown, in this embodiment, the plug-in groove is provided on one side of the top of the gas injection structure close to the axis of the burner base, and the plug-in projection 201 is provided at the bottom of the burner base at the corresponding position of the plug-in groove.

[0056] In this embodiment, the plug-in groove includes a groove bottom wall extending in the horizontal direction and a groove side wall provided on one side of the groove bottom wall away from the axis of the burner base, and the groove side wall extends obliquely upward in the direction away from the axis of the burner base. The plug-in projection 201 protrudes downward from the bottom of the burner base, and the plug-in projection 201 fits with the groove bottom wall and the groove side wall of the plug-in groove.

[0057] Preferably, the top of at least three gas injection structures is provided with plug-in grooves, and the plug-in projections 201 at the bottom of the burner base are arranged corresponding to the plug-in grooves at the top of the gas injection structures one by one.

[0058] As Figure 7 shown, in some other possible embodiments, the plug-in structure includes a groove 20 provided at the bottom of the burner base 2. The groove 20 has the same shape as the top of the gas injection structure 43, and the burner base 2 is sleeved on the top of the gas injection structure 43 through the groove 20.

[0059] Preferably, the top of the gas injection structure 43 is close to the bottom edge of the burner base 2, and at least a part of the side of the top of the gas injection structure 43 away from the axis of the burner base 2 extends to the outer periphery of the burner base 2 and fits with the outer peripheral surface of the burner base 2. The groove 20 is provided on the bottom surface of the burner base 2 and / or on the outer peripheral surface of the burner base 2.

[0060] The top surface of the gas injection structure 43 fits with at least a part of the outer peripheral surface of the burner base 2, which can further improve the stability of the support of the gas injection structure 43 on the burner base 2, and can avoid the burner base 2 from translating relative to the gas injection structure 43 during the use of the gas stove.

[0061] In some preferred embodiments, a chamfer is provided at the corner between the bottom surface and the outer peripheral surface of the burner base 2. The top surface of the gas injection structure 43 abuts against the bottom surface of the burner base 2, and the side of the top surface of the gas injection structure 43 away from the axis of the burner base 2 is wrapped around the chamfer at the bottom of the burner base 2. Preferably, the chamfer at the corner between the bottom surface and the outer peripheral surface of the burner base 2 is a rounded chamfer, and the side of the top surface of the gas injection structure 43 away from the axis of the burner base 2 is an arc-shaped curved surface that fits the rounded chamfer.

[0062] Preferably, the groove 20 is provided at the bottom of the burner base 2 and at the chamfer at the bottom of the burner base 2. When the burner base 2 is installed on the top of the gas injection structure 43, the top of the gas injection structure 43 is fitted into the groove 20, making the appearance of the burner complete.

[0063] In some preferred embodiments, corresponding insertion slots and insertion protrusions 201 are provided between the inner wall of the groove 20 and the top surface of the gas injection structure 43 to further improve the positioning effect of the burner base 2.

[0064] In some specific embodiments, the bottom of the burner base 2 is provided with a groove 20 adapted to the shape of the top of the gas injection structure 43. The inner wall of the groove 20 is provided with insertion protrusions 201, and the top of the gas injection structure 43 is provided with insertion slots corresponding to the insertion protrusions 201. When the burner base 2 is installed on the top of the gas injection structure 43, the insertion protrusions 201 at the bottom of the burner base 2 are inserted into the top of the gas injection structure 43, and the groove 20 at the bottom of the burner base 2 is sleeved on the top of the gas injection structure 43. Through the above settings, while enhancing the positioning effect of the burner base 2, the integrity of the burner can also be enhanced, ensuring a beautiful appearance.

[0065] Preferably, the insertion protrusions 201 are provided on the bottom of the groove 20.

[0066] In some possible embodiments, the suction structure includes a first suction portion provided on the top of the gas injection structure 43 and a second suction portion provided on the bottom of the burner base 2 corresponding to the first suction portion.

[0067] Preferably, the second suction portion is a magnet embedded in the bottom of the burner base 2, and the first suction portion is a ferromagnetic member provided on the top of the gas injection structure 43, or at least a part of the top of the gas injection structure 43 is made of ferromagnetic material, and this region constitutes the first suction portion.

[0068] In this embodiment, the insertion structure between the top of the gas injection structure 43 and the bottom of the burner cap base 2 is uniquely matched. Specifically, the insertion structure between the top of the gas injection structure 43 and the bottom of the burner cap base 2 is an anti-fooling structure, so that the burner cap base 2 is installed on the gas injection structure 43 at a unique angle. Thus, the uniqueness of the installation position of the burner cap base 2 can be ensured, and the accuracy of the installation of the burner cap base 2 is improved. Through the above settings, there is no need to provide an additional circumferential positioning structure between the burner cap base 2 and the burner head 4, and the installation accuracy of the burner cap base 2 can be guaranteed.

[0069] In some possible embodiments, at least three gas injection structures 43 are arranged at intervals along the circumference of the burner cap base 2, and an insertion structure is provided only between the tops of some of the gas injection structures 43 and the bottoms of the burner cap base 2.

[0070] Preferably, in this embodiment, the number of the gas injection structures 43 is set to be odd, and / or the gas injection structures 43 provided with an insertion structure between their bottoms and the bottom of the burner cap base 2 are arranged along the circumference of the burner cap base 2, and their distribution is non-centrally symmetric.

[0071] In some possible embodiments, the distances between multiple groups of insertion structures provided between the tops of different gas injection structures 43 and the bottoms of the burner cap base 2 and the axis of the burner cap base 2 are not completely equal.

[0072] Preferably, the distance between the top of at least one gas injection structure 43 and the axis of the burner cap base 2 is different from the distance between the tops of the remaining gas injection structures 43 and the axis of the burner cap base 2.

[0073] In some possible embodiments, the central angles between multiple groups of insertion structures provided between the tops of different gas injection structures 43 and the bottoms of the burner cap base 2 are not completely equal. Specifically, the angles formed by the connecting lines between multiple groups of insertion structures and the axis of the burner cap base 2 are not completely equal.

[0074] Preferably, in this embodiment, three gas injection structures 43 are provided, and the three gas injection structures 43 are arranged non-collinearly in the horizontal direction, that is, the projections of the three gas injection structures 43 on the horizontal plane form a triangular structure, and the burner cap base 2 is detachably installed on the tops of the three gas injection structures 43, which can ensure the installation stability of the burner cap base 2.

[0075] In this embodiment, among the angles formed by the projections of the three gas injection structures 43 on the horizontal plane, at least one angle is not equal to 120°.

[0076] In some preferred embodiments, in the horizontal direction, these three gas injection structures 43 will not be simultaneously located in the same semi-circular area of the disc-shaped burner cap base 2, so as to achieve stable support for the burner cap base 2.

[0077] Specifically, the three gas injection structures 43 are distributed at different positions of the burner base 2, and 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, thereby 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.

[0078] Preferably, the distances from the gas injection structures 43 to the center of the burner base 2 can be the same or different.

[0079] In this embodiment, the gas injection ports of the gas injection structures 43 are arranged on the sides of the gas injection structures 43, corresponding to the air inlet ends of the ejector pipes at the bottom of the burner base 2. Preferably, the gas injection ports are coaxial with the ejector pipes.

[0080] In this embodiment, the number of ejector pipes at the bottom of the burner base 2 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 only has 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 multiple gas injection ports respectively corresponding to multiple ejector pipes. That is, one gas injection structure 43 has at least one gas injection port.

[0081] In some specific embodiments, three ejector pipes are provided at the bottom of the burner base 2, and the air inlet ends of the three ejector pipes respectively correspond to the gas injection ports of the three gas injection structures 43.

[0082] In this embodiment, the burner base 2 includes an inner ring mixing chamber 21 and an outer ring mixing chamber 22. The ejector pipes include a first ejector pipe 23 communicating with the inner ring mixing chamber 21 and a second ejector pipe 24 communicating with the outer ring mixing chamber 22. The air inlet ends of the first ejector pipe 23 and the second ejector pipe 24 are both arranged near the outer periphery of the outer ring mixing chamber 22, and the gas injection structures 43 corresponding to the air inlet ends of the first ejector pipe 23 and the second ejector pipe 24 are all arranged directly below the outer ring mixing chamber 22, that is, the gas injection structures 43 support the burner base 2 from the bottom of the outer ring mixing chamber 22.

[0083] In this embodiment, two second ejector tubes 24 are provided and 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 the first ejector tube 23 are concentrated on the same side of the burner base 2, ensuring the support stability of the burner base 2.

[0084] 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.

[0085] Preferably, the first ejector tube 23 and the second ejector tube 24 are parallel to each other.

[0086] As Figure 7 shown, in this embodiment, the air inlet ends of the two second ejector tubes 24 face 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 facing direction.

[0087] 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.

[0088] In some specific embodiments, the air outlet end of the second ejector tube 24 extends along the circumferential direction of 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, thereby improving the guiding effect on the gas and primary air mixture.

[0089] In this embodiment, by setting the air inlet ends of the two second ejector tubes 24 to face 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 improving the uniformity of the mixture of gas and primary air and the combustion effect of the gas.

[0090] By arranging the first ejector tube 23 close to one of the second ejector tubes 24 with the same orientation, it can ensure that there is sufficient 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 arrange 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.

[0091] 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.

[0092] In this embodiment, an inner fire cap 211 and an outer fire cap 221 are respectively buckled on the top of the inner mixing chamber 21 and the top of the outer mixing chamber 22, and the gas-air mixture burns on the inner fire cap 211 and the outer fire cap 221.

[0093] In some preferred embodiments, another circumferential positioning structure is further provided between the burner head 4 and the fire cap seat 2. The circumferential positioning structure enables the user to accurately know the correct installation angle of the fire cap seat 2 without distinguishing according to the insertion structure between the gas injection structure 43 and the bottom of the fire cap seat 2, which is beneficial to improving the installation efficiency of the fire cap seat 2. Moreover, the additionally provided circumferential positioning structure can further improve the installation stability of the fire cap seat 2.

[0094] In some possible embodiments, a first positioning portion 251 is further provided on the fire cap seat 2. Along the installation direction of the fire cap seat 2, the first positioning portion 251 is sleeved on the periphery of the combustion control component on the burner head 4. Specifically, the first positioning portion 251 is sleeved on the middle part of the combustion control component, enabling the combustion control component to function normally.

[0095] In this embodiment, the circumferential positioning of the fire cap seat 2 is realized by making full use of the structure on the burner head 4 itself without adding structures to the burner head 4, which is beneficial to simplifying the structure on the panel 1 of the gas stove for installing the fire cap seat 2 and facilitating daily cleaning.

[0106] In some preferred embodiments, an ignition pin sleeve 44 is provided on the burner head 4. The ignition pin 41 is fixed on the burner head 4 through the ignition pin sleeve 44. The ignition pin sleeve 44 is sleeved on the outer periphery of the ignition pin 41, and the first positioning portion 251 is sleeved with the ignition pin sleeve 44.

[0107] Specifically, an installation groove and a plug hole are coaxially arranged on the burner head 4. An internal thread is arranged on the groove wall of the installation groove, and the plug hole is arranged at the bottom of the installation groove.

[0108] The ignition pin 41 includes a main body section and a plug section with gradually decreasing diameters. The plug section is inserted into the plug hole, and the lower end of the main body section abuts against the bottom of the installation groove.

[0109] The inner diameter of the ignition pin sleeve 44 is the same as the outer diameter of the main body section of the ignition pin 41, or the inner diameter of the ignition pin sleeve 44 is slightly larger than the outer diameter of the main body section. An external thread adapted to the internal thread on the groove wall of the installation groove is arranged on the outer peripheral wall at the lower end of the ignition pin sleeve 44. The ignition pin sleeve 44 is sleeved on the outer periphery of the main body section, and the lower end of the ignition pin sleeve 44 is screwed with the groove wall of the installation groove.

[0118] Embodiment II

[0119] In this embodiment, the top surface of the gas injection structure 43 is adapted to the shape of the bottom of the burner cap base 2 for fitting with the bottom of the burner cap base 2. That is, the abutting portion between the gas injection structure 43 and the burner cap base 2 is mutually fitted.

[0120] The difference between this embodiment and Embodiment I is that the top surface of the gas injection structure 43 has a microscopic uneven structure, presenting a rough characteristic. Thus, the friction coefficient between the top of the gas injection structure 43 and the bottom of the burner cap base 2 can be increased, the support stability of the gas injection structure 43 to the burner cap base 2 can be improved, and relative displacement between the burner cap base 2 and the gas injection structure 43 can be avoided during use.

[0121] In some preferred embodiments, the surface roughness of the top surface of the gas injection structure 43 is greater than or equal to the surface roughness of the bottom of the burner cap base 2.

[0122] Embodiment III

[0123] As Figure 1 shown, in the embodiment of the present invention, a gas stove is further provided. The gas stove includes the burner in Embodiment I or Embodiment II above, and further includes a panel 1 and a housing 10.

[0124] 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.

[0125] 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.

[0126] The panel 1 is provided with an installation opening 12. 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 burner cap base 2 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 opened on the panel 1 and improve the aesthetics of the panel 1.

[0127] As Figure 4 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 whose air inlet end faces 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 whose air inlet end faces the second direction is arranged in the other installation opening 12.

[0128] 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.

[0129] Preferably, the thermocouple 42 and the ignition pin 41 correspond to the installation opening 12 with one gas injection structure 43 inside, and the columnar protrusion 26 corresponds to the installation opening 12 with two gas injection structures 43 inside.

[0130] In this embodiment, a decorative cover 11 for shielding the installation opening 12 is installed at the installation opening 12. The decorative cover 11 is provided with 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 installation part.

[0131] Preferably, in this embodiment, the decorative cover 11 includes a plate portion covering the installation opening 12 and fitting with the panel 1, and a cylindrical portion extending vertically downward from the middle of the plate portion and having an outer periphery fitting with the inner wall of the installation opening 12. The first opening 111 and / or the second opening 112 are arranged in the middle of the plate portion.

[0132] 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 part 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 installation structures such as screws.

[0133] Preferably, the lower end of the columnar protrusion 26 is threadedly connected to the burner head.

[0134] Preferably, the upper end of the columnar protrusion 26 is in contact with the bottom of the burner base 2, that is, the columnar protrusion can also support the burner base, further improving the installation stability of the burner base.

[0135] In this embodiment, the pot support 3 of the gas stove is fixedly connected to the burner base 2. The pot support 3 includes a support ring 31 arranged around the burner base 2 and support feet connected to the support ring 31.

[0136] Specifically, the support ring 31 is arranged on the outer periphery of the burner base 2. The inner diameter of the support ring 31 is the same as the outer diameter of the burner base 2, or the inner diameter of the support ring 31 is slightly larger than the outer diameter of the burner base 2. The support ring 31 extends in a direction away from the axis of the burner base 2. The inner periphery of the support ring 31 is connected to the outer periphery of the burner base 2.

[0137] Preferably, the outer diameter of the support ring 31 is greater than or equal to the maximum distance between the edge of the installation opening 12 and the axis of the burner base 2, that is, the projection of the outer edge of the support ring 31 on the panel 1 surrounds the outside of the installation opening 12. Thus, the overall structure formed by the pot support 3 and the burner base 2 can cover the installation opening 12 on the panel 1, further improving the aesthetics of the gas stove.

[0138] 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.

[0139] 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. 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 support 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.

[0140] In some preferred embodiments, in a direction away from the axis of the burner base 2, the support ring 31 has a first extension section 312 that extends upwardly and obliquely in a 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 provision of the first extension section 312 can facilitate the convergence of the heat of flame combustion towards the bottom of the cookware, improving the utilization rate of heat. At the same time, the provision of the second extension section 313 can also ensure the shielding effect on the decorative cover 11, ensuring aesthetics.

[0141] In this embodiment, the pot support 3 is coaxial with the burner base 2.

[0142] In some possible embodiments, the feet are only used to support the cookware and are provided at the top of the support ring and do not extend below the support ring. Alternatively, the lower end of the feet extends below the support ring, but the part of the feet that extends below the support ring is hidden by the support ring. Specifically, when the user is using it normally, the part of the feet located below the support ring cannot be seen, giving the pot support a suspended effect and improving the user's visual experience.

[0143] In some other possible embodiments, the lower end of the feet is close to the panel 1 of the gas stove.

[0144] The feet 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 supporting force to the support ring 31 through the feet, improving the supporting stability of the pot support 3 for the cookware.

[0145] Preferably, the bottom of the feet fits with the panel 1 of the gas stove, and when no cookware is placed on the pot support 3, the feet do not exert pressure on the panel 1, or there is a gap between the lower end of the feet and the panel 1 of the gas stove.

[0146] In this embodiment, a first foot 32 is provided on the support ring 31. The first foot 32 is provided at the top of the support ring 31, and the pot support 3 supports the cookware through the first foot 32.

[0147] In this embodiment, a plurality of the first feet 32 are provided and arranged evenly in the circumferential direction of the support ring 31 to ensure the supporting stability of the cookware. Preferably, four first feet 32 are provided and arranged evenly in the circumferential direction of the support ring 31.

[0148] In some specific embodiments, the first foot 32 is a plate-shaped one that extends radially along the support ring 31. A supporting portion that extends towards the axis of the support ring 31 is provided at its top, and the top of the supporting portion is provided as an inclined surface that extends downwardly in a direction close to the axis of the support ring 31.

[0149] In some preferred embodiments, a second supporting leg 33 is provided at the bottom of the supporting ring 31, and the bottom of the second supporting leg 33 is close to the panel 1 of the gas stove.

[0150] Specifically, 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 supporting leg 33 will not exert pressure on the panel 1, and may not even come into contact with the panel 1, thus avoiding the occurrence of obvious indentations on the panel 1 due to the long-term extrusion of the panel 1 by the second supporting leg 33. At the same time, the setting of the second supporting leg 33 can further prevent the cookware supported on the pot support 3 from tipping over, improving the working stability of the gas stove.

[0151] Preferably, in this embodiment, a gap is provided between the bottom of the second supporting leg 33 and the panel 1 of the gas stove.

[0152] In this embodiment, the second supporting leg 33 is a plate-shaped member extending radially along the supporting ring 31.

[0153] Preferably, in this embodiment, a plurality of second supporting legs 33 are provided corresponding one-to-one to the first supporting legs 32.

[0154] Preferably, the second supporting leg 33 and the first supporting leg 32 are integral parts formed on the supporting ring 31, and the first supporting leg 32 and the second supporting leg together constitute the supporting leg.

[0155] Preferably, in this embodiment, a U-shaped member 34 is provided at the bottom of the second supporting leg 33. The U-shaped member 34 is made of a flexible material and is fixed to the bottom of the second supporting leg 33, covering the bottom of the second supporting leg 33 therein. The bottom of the second supporting leg 33 contacts the panel 1 through the U-shaped member 34, which can prevent the bottom of the second supporting leg 33 from scratching the panel 1 when contacting the panel 1.

[0156] In this embodiment, the U-shaped member 34 can be made of silicone material or heat-resistant rubber material.

[0157] Preferably, in this embodiment, the bottom of the second supporting 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 supporting leg 33 can support the whole formed by the burner base 2 and the pot support 3, enabling the whole formed by the burner base 2 and the pot support 3 to remain stable, and preventing the bottom of the burner base 2 from contacting the supporting surface for placing the burner base 2 and the pot support 3, thereby avoiding dirt from entering the ejector pipe.

[0177] Preferably, in this embodiment, a plurality of second connecting portions 36 are arranged at intervals along the circumferential direction of the pot support 3, and a plurality of first connecting portions 35 corresponding to the second connecting portions 36 one by one are arranged on the outer peripheral wall of the pot support 3. When the pot support 3 is sleeved on the outer periphery of the burner base 2 and rotates relative to the burner base 2, each first connecting portion 35 is respectively engaged in the connecting groove 360 of the corresponding second connecting portion 36.

[0178] In this embodiment, the second connecting portion 36 can be arranged at the top of the pot support 3 or at the bottom of the pot support 3.

[0179] Preferably, in order to improve the aesthetics of the gas stove, the second connecting portion 36 is arranged at the bottom of the pot support 3. In this embodiment, the pot support 3 is sleeved on the outer periphery of the burner base 2 from the top of the burner base 2, so that the second connecting portion 36 and the first connecting portion 35 on the burner base 2 are at the same height, and then the pot support 3 is rotated so that the connecting groove 360 on the second connecting portion 36 is sleeved on the first connecting portion 35.

[0180] As Figure 9 shown, in this embodiment, the pot support 3 includes a support ring 31 arranged around the burner base 2 and feet arranged on the support ring 31.
