[0053] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the following embodiments.

[0054] The utility model provides a gas stove, which includes an energy-gathering ring assembly. Figures 1-6 As shown, the energy gathering ring assembly includes an energy gathering ring bracket 10, an energy gathering ring 20 and multiple pot brackets 30, each of the multiple pot brackets 30 includes a first connecting part 301, a second connecting part 302 and a supporting part 303 for supporting the bottom of the pot connected in sequence from bottom to top, and the multiple pot brackets 30 are evenly distributed on the energy gathering ring bracket 10 along the circumferential direction, and the first connecting part 301 is connected to the energy gathering ring bracket 10, and the energy gathering ring 20 is connected to the multiple second connecting parts 302, so that a secondary air gap is formed between the energy gathering ring 20 and the energy gathering ring bracket 10, and an eddy current gap is formed between the energy gathering ring 20 and the pot bottom; the energy gathering ring 20 includes a vertebral ring part 202, and the top and bottom surfaces 102 of the vertebral ring part 202 respectively have a first inclined surface 2021 and a second inclined surface 2022, the first inclined surface 2021 extends from the outside to the inside and obliquely downward, and the second inclined surface 2022 extends from the outside to the inside and obliquely upward.

[0055] In this embodiment, the energy gathering ring assembly includes an energy gathering ring bracket 10, an energy gathering ring 20 and a plurality of pot brackets 30, and the plurality of pot brackets 30 include a first connecting portion 301 at the bottom, a second connecting portion 302 upward in sequence and a supporting portion 303 at the top for supporting the bottom of the pot. Each pot bracket 30 is an integrally formed thin sheet and is evenly distributed along the circumference of the energy gathering ring bracket 10. The first connecting portion 301 of each pot bracket 30 is welded and fixed to the energy gathering ring bracket 10. The pot bracket 30 is inclined from bottom to top toward the center of the energy gathering ring assembly. The second connecting portions 302 of the plurality of pot brackets 30 are welded and fixed to the energy gathering ring 20. There is a gap between the energy gathering ring bracket 10 and the energy gathering ring 20, which can facilitate the supply of secondary air on the one hand and reduce the overflow of high-temperature gas on the other hand. The energy gathering ring 20 in this case includes a vertebral ring portion 202, a vertebral ring portion 203, and a vertebral ring portion 204. Both the upper and lower surfaces of the ring portion 202 have inclined surfaces, and the top surface of the vertebral ring portion 202 has a first inclined surface 2021, which extends from the outside to the inside and obliquely downward. When the upper part of the energy gathering ring 20 with such a structure has a certain inclination angle and width, it is conducive to forming an air vortex zone in the gap between the energy gathering ring 20 and the bottom of the pot, which can effectively avoid the loss of high-temperature flue gas generated by the combustion of the burner 60 placed on the upper part of the pot support 30, and this vortex zone can increase the residence time of the high-temperature flue gas, enhance the heat exchange with the bottom of the pot, and improve the combustion efficiency; the bottom surface 102 of the vertebral ring portion 202 has a second inclined surface 2022, which extends from the outside to the inside and obliquely upward. Such a bottom surface 102 structure of the vertebral ring portion 202 is also conducive to reducing the supplementary resistance of secondary air and is conducive to the supply of secondary air.

[0056] like Figure 2-Figure 4 As shown, the energy gathering ring 20 also includes an outer ring portion 201, one side of the outer ring portion 201 is connected to the outer periphery 101 surface of the vertebral annulus portion 202, and the other side of the outer ring portion 201 has an outer arc surface 2011, and the upper and lower ends of the outer arc surface 2011 are smoothly transitioned between the first inclined surface 2021 and the second inclined surface 2022 respectively.

[0057] Specifically, the energy gathering ring 20 of this embodiment has an outer ring portion 201, and the outer side of the outer ring portion 201 has an outer arc surface 2011, the upper end of the outer arc surface 2011 and the first inclined surface are smoothly transitioned and connected into one, the lower end of the outer arc surface 2011 and the second inclined surface are smoothly transitioned and connected into one, the inner side of the outer ring portion 201 and the outer periphery 101 surface of the vertebral ring portion 202 are connected into one, the outer ring portion 201 and the vertebral ring portion 202 together constitute a part of a solid, one-piece, oblate energy gathering ring 20, and external air can enter the inner side of the energy gathering ring 20 along the outer arc surface 2011 of the outer ring portion 201, and then pass through the lower end of the vertebral ring portion 202 and the second inclined surface to form secondary air, so that the gas of the burner 60 can be burned more fully.

[0058] like Figure 2-Figure 6 As shown, the energy gathering ring 20 of this embodiment also includes an inner ring portion 203, one side of the inner ring portion 203 is connected to the inner wall surface of the vertebral ring portion 202, and the other side of the inner ring portion 203 has an inner arc surface 2031, and the upper and lower ends of the inner arc surface 2031 smoothly transition between the first inclined surface 2021 and the second inclined surface 2022 respectively.

[0059] Specifically, the energy-gathering ring 20 of this embodiment further comprises an inner ring portion 203, the side of the inner ring portion 203 close to the burner 60 having an inner arc surface 2031, the upper end of the inner arc surface 2031 smoothly transitions to and is connected to the first inclined surface as a whole, the side of the inner ring portion 203 close to the annulus portion 202 is connected to the inner wall surface of the annulus portion 202 as a whole, and the inner ring portion 203, the annulus body, and the outer ring portion 201 are all part of the integrated energy-gathering ring 20. When external air enters the inner side of the energy-gathering ring 20, it can flow more smoothly along the inner arc surface 2031 of the inner ring portion 203, thereby replenishing secondary air for the burner 60.

[0060] like Figure 2-Figure 3 and Figure 6 As shown, the energy-gathering ring 20 of this embodiment is an oblate solid structure with a large outer circle and a small inner circle.

[0061] Specifically, the oblate solid structure of the energy-gathering ring 20, with its larger outer circle and smaller inner circle, further facilitates the flow of smoke and its mixing with secondary air. Compared to conventional pot racks, the energy-gathering ring 20 of this embodiment is smaller. When placed on a pot 50 for use, the normal diameter of the pot 50 will be larger than the outermost diameter of the energy-gathering ring 20 of this embodiment. This creates a negative pressure zone between the lower portion of the pot 50 and the upper portion of the energy-gathering ring assembly. High-temperature smoke escaping from the upper portion of the energy-gathering ring 20 flows downward along the outer edge of the energy-gathering ring 20 and mixes with the secondary air, preheating the secondary air and improving combustion efficiency. Furthermore, the oblate solid structure of the energy-gathering ring 20 of this embodiment is simple in structure. The outer arc surface 2011 of the outer ring 201 and the inner arc surface 2031 of the inner ring 203 create no concave structures throughout the energy-gathering ring 20, making it less likely to harbor dirt and grime. This reduces dead corners and facilitates daily cleaning of the energy-gathering ring 20.

[0062] like Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, the inclination angle of the first inclined surface 2021 of this embodiment is 15° to 18°.

[0063] Specifically, the upper end of the energy-gathering ring 20 of this embodiment slopes downward from the outer ring to the inner ring, with the first inclined surface 2021 having an inclination angle of 15° to 18°. With a smooth surface and an inclination angle of 15° to 18°, liquid that overflows during daily cooking can flow directly out along the first inclined surface 2021, preventing the energy-gathering ring 20 from being contaminated. When the inclination angle of the first inclined surface 2021 at the upper portion of the energy-gathering ring 20 is 15° to 18°, it is more conducive to forming an air vortex zone in the gap between the energy-gathering ring 20 and the bottom of the pot, preventing the escape of high-temperature gases. The upward inclination from the inner ring of the energy-gathering ring 20 to the outer ring of the energy-gathering ring 20 also creates a pressure-diffusion effect on the high-temperature gases, slowing the exhaust velocity of the high-temperature gases and preventing them from directly escaping. This allows the gases to contact the cookware upward, raising the temperature of the pot bottom and improving the thermal efficiency of the stove.

[0064] like Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, the inclination angle of the second inclined surface 2022 of this embodiment is 4° to 8°.

[0065] Specifically, the lower end of the energy-gathering ring 20 of this embodiment tilts upward from the outer ring to the inner ring, with the second inclined surface 2022 having an angle of 4° to 8°. This creates a structure with a higher interior and lower exterior at the lower end of the energy-gathering ring 20, which helps reduce resistance to secondary air replenishment and facilitates the supply of secondary air. This also facilitates the clearance between the lower portion of the energy-gathering ring 20 and the energy-gathering ring support 10. The negative pressure zone formed at the lower portion of the energy-gathering ring 20 also supplies more secondary air to the burner 60, improving the burner's flame stabilization performance and achieving higher combustion efficiency.

[0066] like Figure 3-Figure 5 As shown, the energy ring bracket 10 of this embodiment is in the shape of a plate, and the bottom surface 102 of the energy ring bracket 10 has a contact surface for support, and the multiple pot brackets 30 are all connected to the top surface of the energy ring bracket 10.

[0067] Specifically, the energy gathering ring bracket 10 in this embodiment is a plate-shaped metal plate, the bottom surface 102 of which is in contact with the surface of the stove or the liquid receiving tray to support the energy gathering ring bracket 10. Due to the large surface area of the contact surface, the chassis is very stable. The multiple pot brackets 30 in this case are evenly welded and fixedly connected to the top surface of the energy gathering ring bracket 10. During use, when the pot 50 is placed on the pot bracket 30, the energy gathering ring bracket 10 also enhances the stability of the support for the pot 50. Such a structure avoids the instability of relying solely on a few pot brackets 30 to support the positioning.

[0068] like Figure 3-Figure 5 As shown, the outer periphery 101 of the energy-gathering ring bracket 10 of this embodiment is square, and the middle area of the energy-gathering ring bracket 10 has a circular hole for the burner 60 to pass through.

[0069] Specifically, the energy-gathering ring support 10 in this embodiment has a square outer perimeter and a circular inner perimeter. Its outer perimeter 101 is square, and its center region has a circular hole extending therethrough. The hole is precisely sized to allow the burner 60 to pass through the bottom. In daily use, the integrated energy-gathering ring support 10 securely supports the pot 50 via multiple pot supports 30 welded to it.

[0070] like Figure 2-Figure 5 As shown, the multiple pot supports 30 of this embodiment all include an inner extension portion 304, one end of the inner extension portion 304 is connected to the support portion 303, the other end of the inner extension portion 304 extends inward along the center near the energy gathering ring assembly, and the bottom of the inner extension portion 304 is connected to the energy gathering ring 20.

[0071] Specifically, the support portion 303 of the multiple pot supports 30 in this embodiment is located at the uppermost end of the pot support 30, and the support portion 303 is parallel to the energy gathering ring support 10. The multiple pot supports 30 also include an inner extension portion 304. The outer end of the inner extension portion 304 away from the center of the energy gathering ring assembly is fixedly connected to the support portion 303 to form an integral body. The other inner end of the inner extension portion 304 extends inwardly along the center close to the center of the energy gathering ring assembly. The bottom of the inner extension portion 304 is welded and fixedly connected to the upper end of the energy gathering ring 20. The inner end of the inner extension portion 304 does not exceed the inner ring portion 203 of the energy gathering ring 20. The top of the inner extension portion 304 is an inclined surface inclined downward from the outer end to the inner end. When the flat-bottomed pot 50 is used daily, the bottom of the pot 50 is only in contact with the supporting parts 303 of the multiple pot supports 30. The bottom of the pot 50 and the inner extension part 304 of the pot support 30 are not in direct contact, and a gap is left; when the pointed-bottomed wok is used, the inner extension part 304 is in contact with the bottom of the pot along the pointed bottom, making the pointed-bottomed wok more stable when placed on the gas stove 40.
