[0043] As described in the background section, an integrated cooktop is a kitchen appliance that integrates multiple kitchen functions. An integrated cooktop typically includes a cooktop that heats pots and pans for various cooking operations such as frying, stir-frying, boiling, and stewing. The cooktop includes a burner. The burner consists of an outer burner cap and an inner burner cap. The inner burner cap is located inside the outer burner cap and has inner ring flame holes, while the outer burner cap has outer ring flame holes on its outer wall. Gas flows out from the inner ring flame holes of the inner burner cap and is ignited to form an inner ring flame. Gas flows out from the outer ring flame holes of the outer burner cap and is ignited to form an outer ring flame. However, during cooking using both inner and outer ring flames, food in the pot may sometimes remain partially uncooked.

[0044] To address the aforementioned problems, this utility model provides a burner structure, a burner, a stove, and an integrated stove. The burner structure includes an inner burner 100 and an outer burner 200. The inner burner 100 is provided with an inner ring flame hole group 110, and the outer burner 200 is provided with a middle ring flame hole group 230 and an outer ring flame hole group 210. During use, the gas flows out through the inner ring flame hole group 110, the middle ring flame hole group 230, and the outer ring flame hole group 210 and is ignited to form an inner ring flame, a middle ring flame, and an outer ring flame. Through the inner ring flame, the middle ring flame, and the outer ring flame, the heating area is effectively expanded, and the overall heating uniformity of the pot bottom is improved, thereby avoiding the problem of food in the pot being partially uncooked.

[0045] The following detailed description, in conjunction with specific embodiments, illustrates a burner structure, burner, stove, and integrated stove provided by this utility model.

[0046] like Figures 1 to 3 As shown, this embodiment of the invention provides a flame cap structure applied to a burner. The height direction of the burner is the Z-direction (see...). Figure 4 (As shown). The +Z side of the burner is the top of the burner, i.e., the upper part of the burner. The -Z side of the burner is the bottom of the burner, i.e., the lower part of the burner.

[0047] The flame cap structure includes an inner flame cap 100 and an outer flame cap 200. The inner flame cap 100 is provided with an inner ring flame hole group 110, and the outer flame cap 200 is provided with a through hole 201 that surrounds the inner flame cap 100. A gap is provided between the outer flame cap 200 and the inner flame cap 100. The outer flame cap 200 is provided with a middle ring flame hole group 230 and an outer ring flame hole group 210. The outer ring flame hole group 210 is provided on the outer side wall of the outer flame cap 200, and the middle ring flame hole group 230 is provided between the outer ring flame hole group 210 and the inner ring flame hole group 110 in the radial direction of the through hole 201.

[0048] It should be noted that the gas flows out through the inner ring flame hole group 110, the middle ring flame hole group 230 and the outer ring flame hole group 210 and is ignited to form an inner ring fire, a middle ring fire and an outer ring fire. The inner ring fire is responsible for the concentrated heating of the central area of ​​the pot bottom, while the middle ring fire and the outer ring fire cover the middle and edge areas of the pot bottom. The inner ring fire, middle ring fire and outer ring fire achieve layered heating of the inner, middle and outer rings of the pot bottom, thereby compensating for the low temperature area between the inner and outer rings of the pot bottom and improving the overall uniformity of heating of the pot bottom.

[0049] The inner ring flame hole group 110 includes a plurality of spaced inner ring flame holes 111, which are disposed on the outer side wall of the inner flame cover 100.

[0050] In one possible implementation, the outer flame cap 200 is provided with a first air passage 240 and a second air passage 250. The first air passage 240 is connected to the outer ring flame hole group 210, and the second air passage 250 is connected to the middle ring flame hole group 230.

[0051] In actual operation, the gas flows through the first gas passage 240 and is ignited from the outer ring burner group 210, while the gas flows through the second gas passage 250 and is ignited from the middle ring burner group 230. The first gas passage 240 and the second gas passage 250 are independent gas passages. By controlling the opening and closing of the first gas passage 240 and the second gas passage 250, different combinations of gas output methods can be achieved according to different cooking scenarios of different cookware.

[0052] In this embodiment, there are three flame patterns. The first pattern is that the outer ring flame hole group 210, the middle ring flame hole group 230, and the inner ring flame hole group 110 all emit flame simultaneously. The second pattern is that the middle ring flame hole group 230 and the inner ring flame hole group 110 emit flame, while the outer ring flame hole group 210 does not emit flame. The third pattern is that only the inner ring flame hole group 110 emits flame. Infrared temperature measurement was performed for different flame patterns. The first pattern showed better uniformity on a flat-bottomed pan, with the largest coverage area on the bottom of the pan. The second pattern showed better uniformity on a wok, with more concentrated heat. The third pattern showed better uniformity on a saucepan, making it suitable for cooking scenarios such as simmering soup and cooking porridge.

[0053] In one possible implementation, see Figure 2 The central ring fire hole group 230 includes a plurality of central ring fire hole portions 231, which are spaced apart along the circumferential direction of the through hole 201.

[0054] It should be noted that the multiple central ring flame holes 231 are spaced apart along the circumference of the through hole 201, and the annular flame evenly covers the bottom of the pot, making heat transfer more uniform. Furthermore, the evenly distributed flames ignite each other through the central ring flame holes 231, maintaining combustion stability and preventing backfire due to excessively high local gas concentration or flame lift-off due to interrupted airflow. The spaced arrangement of the multiple central ring flame holes 231 also ensures a sufficient oxygen supply; the oxygen can be fully mixed with the gas through the gap between adjacent central ring flame holes 231, preventing incomplete combustion.

[0055] Furthermore, the extension directions of two adjacent middle ring flame holes 231 intersect; in this embodiment, the middle ring flame hole 231 is elongated; there are six middle ring flame holes 231; the specific shape of the six elongated middle ring flame holes 231 is that of a regular hexagon after each side is rotated counterclockwise or clockwise by the same angle, and the position of each side is shaped accordingly.

[0056] As an alternative implementation, the multiple central ring fire holes 231 form a polygonal structure.

[0057] In one possible implementation, see Figure 2 and Figure 3 The outer flame cap 200 includes a plurality of protrusions 260 spaced apart along the circumferential direction of the through hole 201. Each protrusion 260 is provided with a central ring flame hole portion 231. Along the direction tangent to the through hole 201, that is, along the extension direction of the central ring flame hole portion 231, the central ring flame hole portion 231 includes a plurality of spaced central ring holes 232.

[0058] In one possible implementation, the outer ring flame hole group 210 includes a plurality of outer ring flame holes 211, and the outer side wall includes a plurality of connecting walls 220 along the outer periphery of the outer flame cover 200. Two adjacent connecting walls 220 are connected to each other, and each connecting wall 220 is provided with at least one outer ring flame hole 211.

[0059] Specifically, there are six connecting walls 220; the shape formed by the six connecting walls 220 can be a regular hexagon.

[0060] In this embodiment, the protrusion 260 is provided with at least one first inclined surface 261, and the outer periphery of the outer flame cover 200 is provided with a connecting wall 220. The first inclined surface 261 and the connecting wall 220 are provided and connected in a one-to-one correspondence. The top of the first inclined surface 261 is inclined towards the inside of the outer flame cover 200 relative to the bottom of the first inclined surface 261. The outer ring flame hole group 210 is located below the extending direction of the first inclined surface 261.

[0061] like Figure 4As shown, it should be noted that when the pot overflows, a large amount of liquid will spill out. Since the protrusion 260 is located on the top of the outer flame cover 200, the overflowing liquid will first contact the first inclined surface 261 on the protrusion 260, and the overflowing liquid will move under the guidance of the first inclined surface 261. Since the liquid has a certain speed, after the liquid leaves the first inclined surface 261, the trajectory of the liquid under the action of inertia and gravity is a parabolic trajectory. Furthermore, the outer ring flame hole group 210 is located below the extension direction of the first inclined surface 261, and the trajectory of the liquid is far away from the outer ring flame hole 211 on the connecting wall 220, thereby preventing the overflowing liquid from blocking the outer ring flame hole group 210.

[0062] Figure 4 The arrows in the diagram indicate the direction of liquid flow.

[0063] In one possible implementation, see Figure 2 The outer flame cap 200 has a channel 270 between two adjacent protrusions 260. The channel 270 includes a first end 271 and a second end 272. The first end 271 communicates with the through hole 201, and the second end 272 communicates with the outer periphery of the outer flame cap 200. In the thickness direction (Z direction) of the outer flame cap 200, the dimension between the first end 271 and the bottom of the outer flame cap 200 is greater than the dimension between the second end 272 and the bottom of the outer flame cap 200.

[0064] Specifically, in this embodiment, the channel 270 has a shape that is higher inside and lower outside. When the pot overflows, a large amount of liquid will overflow, and some of the liquid will flow into the channel 270. Since the channel 270 has a shape that is higher inside and lower outside, the liquid will move towards the second end 272 under the action of gravity after entering the channel 270. Finally, the liquid will flow out from the second end 272, realizing the drainage function and preventing the liquid from accumulating in the channel 270 and causing the channel 270 to be blocked.

[0065] It should be noted that by setting up channel 270, an adequate supply of oxygen can be ensured. The oxygen can be fully mixed with the internal combustion gas through channel 270 to avoid incomplete combustion.

[0066] In one possible implementation, the channel 270 includes a second side surface 273 connected to the connecting wall 220, the second side surface 273 is provided with a central ring hole 232, the protrusion 260 is provided with a second inclined surface 262 connected to the second side surface 273, the top of the second inclined surface 262 is inclined away from the channel 270 relative to the bottom of the second inclined surface 262, and the central ring hole 232 is located below the extending direction of the second inclined surface 262.

[0067] It should be noted that a large amount of liquid will overflow when the pot overflows. The second inclined surface 262 can prevent the liquid from blocking the middle ring hole 232. Since the protrusion 260 is set on the top of the outer flame cap 200, some of the overflowing liquid will come into contact with the second inclined surface 262 on the protrusion 260, and the overflowing liquid will move under the guidance of the second inclined surface 262. Since the liquid has a certain speed, after the liquid leaves the second inclined surface 262, the trajectory of the liquid under the action of inertia and gravity is a parabolic trajectory. Furthermore, the middle ring flame hole is located below the extension direction of the second inclined surface 262, and the trajectory of the liquid is far away from the middle ring flame hole on the second side surface 273, thereby preventing the overflowing liquid from blocking the middle ring flame hole.

[0068] Specifically, the channel 270 includes a third side 274 connected to the connecting wall 220 and the second side 273. The protrusion 260 is provided with a third inclined surface 263 connected to the third side 274. The top of the third inclined surface 263 is inclined away from the channel 270 relative to the bottom of the third inclined surface 263. The tops of the first inclined surface 261, the second inclined surface 262, and the third inclined surface 263 intersect at the apex of the protrusion 260.

[0069] In this embodiment, the first inclined surface 261, the second inclined surface 262, and the third inclined surface 263 form a structure similar to a triangular pyramid.

[0070] In one possible implementation, a first arc surface 264 connects the first inclined surface 261 and the second inclined surface 262, and the first arc surface 264 is connected to the connecting wall 220. Both the first inclined surface 261 and the second inclined surface 262 are tangent to the first arc surface 264. A second arc surface 265 connects the second inclined surface 262 and the third inclined surface 263, and the second arc surface 265 is connected to the second side surface 273. Both the second inclined surface 262 and the third inclined surface 263 are tangent to the second arc surface 265.

[0071] It should be noted that during cleaning or disassembly, users' fingers can easily be accidentally scratched or cut by these sharp edges. This sharpness is eliminated by incorporating the first curved surface 264 and the second curved surface 265. During manufacturing, curved edges are less likely to produce burrs or are easier to handle compared to sharp-angled edges.

[0073] The flame cap structure in this embodiment is the same as the flame cap structure provided in any of the above embodiments, and can bring the same or similar technical effects. It will not be described in detail here, but can be referred to the description of the above embodiments.

[0074] Thirdly, see Figure 5 This utility model provides a stove, including the burner described above.

[0075] The burner in this embodiment has the same structure as the burner provided in any of the above embodiments and can bring the same or similar technical effects. It will not be described in detail here. For details, please refer to the description of the above embodiments.

[0076] The cooktop also includes a base, a glass panel, a pot rack, and cookware. The glass panel is mounted on the base, the burner is mounted on the base, the pot rack is placed on the glass panel, the pot rack is wrapped around the outside of the burner, and the cookware is placed on the pot rack.
