[0041] 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. In related technologies, the cooktop includes a burner. The burner includes an outer burner cap and an inner burner cap, with the inner burner cap located inside the outer burner cap. The outer wall of the outer burner cap has outer ring flame holes. Gas flows out from the outer ring flame holes of the outer burner cap and is ignited to form an outer ring flame.

[0042] However, the broth and oil that overflow during cooking can easily clog the outer ring burner holes, leading to difficulty in ignition and abnormal flames.

[0043] To solve the above problems, this utility model provides an outer burner cap, a burner, a stove and an integrated stove. The outer burner cap includes an outer burner cap body 100 and a protrusion 200. The protrusion 200 is disposed on the top of the burner cap body. A first inclined surface 210 is provided on the protrusion 200. The top of the first inclined surface 210 is inclined towards the inside of the outer burner cap relative to the bottom of the first inclined surface 210. The outer ring fire hole 120 is located below the extending direction of the first inclined surface 210.

[0044] When overflow occurs during cooking, the broth will first come into contact with the first inclined surface 210 of the protrusion 200, and under the guidance of the first inclined surface 210, it will move away from the outer ring burner hole 120, thereby preventing the broth from clogging the outer ring burner hole 120 when overflowing, thus solving the problem that overflowing broth easily clogs the outer ring burner hole 120.

[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] Firstly, such as Figure 1 and Figure 2 As shown, this embodiment of the invention provides an outer flame cap, applied to a burner. The height direction of the burner is the Z-direction (see...). Figure 3(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 outer flame cover includes an outer flame cover body 100 and a protrusion 200. The outer flame cover body 100 has at least one first side surface 110 on its outer periphery, and an outer ring flame hole 120 is provided on the first side surface 110. The protrusion 200 is provided on the top of the outer flame cover body 100, and the protrusion 200 has at least one first inclined surface 210. The first inclined surface 210 is connected to the first side surface 110. The top of the first inclined surface 210 is inclined towards the inside of the outer flame cover relative to the bottom of the first inclined surface 210. The outer ring flame hole 120 is located below the extending direction of the first inclined surface 210.

[0048] In this embodiment, both the first inclined surface 210 and the first side surface 110 are planes. The first inclined surface 210 intersects with the first side surface 110.

[0049] It should be noted that when the pot overflows, a large amount of liquid will spill out. Since the protrusion 200 is located on the top of the outer flame cap body 100, the overflowing liquid will first come into contact with the first inclined surface 210 on the protrusion 200, and the overflowing liquid will move under the guidance of the first inclined surface 210. Since the liquid has a certain speed, after the liquid leaves the first inclined surface 210, the trajectory of the liquid under the action of inertia and gravity is a parabolic trajectory. Furthermore, the outer ring flame hole 120 is located below the extension direction of the first inclined surface 210, and the trajectory of the liquid is far away from the outer ring flame hole 120 on the first side surface 110, thereby preventing the overflowing liquid from blocking the outer ring flame hole 120.

[0050] In one possible implementation, a through hole 101 is provided on the inner side of the outer flame cap body 100, and a plurality of spaced first side surfaces 110 are provided along the outer periphery of the outer flame cap body 100. The protrusion 200 includes a plurality of spaced protrusions 201, and each protrusion 201 is provided with a first inclined surface 210.

[0051] Specifically, the protrusion 200 includes six protrusions 201, which are evenly spaced and arranged along the circumferential direction of the through hole 101.

[0052] Each protrusion 201 has a corresponding first inclined surface 210.

[0053] As an alternative implementation, the number of protrusions 201 can be reasonably increased or decreased according to actual needs.

[0054] The number of first side surfaces 110 is multiple, making the outer periphery of the outer flame cover body 100 polygonal. In this embodiment, the number of first side surfaces 110 is six.

[0055] like Figure 3 As shown, in one possible implementation, the outer flame cap body 100 has a channel 300 between two adjacent protrusions 201. The channel 300 includes a first end 310 and a second end 320. The first end 310 communicates with the through hole 101, and the second end 320 communicates with the outer periphery of the outer flame cap body 100. In the thickness direction (Z direction) of the outer flame cap body 100, the dimension between the first end 310 and the bottom of the outer flame cap body 100 is greater than the dimension between the second end 320 and the bottom of the outer flame cap body 100.

[0056] Specifically, in this embodiment, the channel 300 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 300. Since the channel 300 has a shape that is higher inside and lower outside, the liquid will move towards the second end 320 under the action of gravity after entering the channel 300. Finally, the liquid will flow out from the second end 320, realizing the drainage function and preventing the liquid from accumulating in the channel 300 and causing the channel 300 to be blocked.

[0057] It should be noted that by setting up channel 300, a sufficient supply of oxygen can be ensured. The oxygen can be fully mixed with the gas flowing out of the middle ring burner 331 through channel 300, thus avoiding incomplete combustion in the middle ring burner 331.

[0058] Figure 3 The arrows in the diagram indicate the direction of liquid flow.

[0059] In one possible implementation, see Figure 2 and Figure 3 The channel 300 includes a second side 330 connected to the first side 110. A central ring flame hole 331 is provided on the second side 330. The protrusion 201 is provided with a second inclined surface 220 connected to the second side 330. The top of the second inclined surface 220 is inclined away from the channel 300 relative to the bottom of the second inclined surface 220. The central ring flame hole 331 is located below the extending direction of the second inclined surface 220.

[0060] In this embodiment, both the second inclined surface 220 and the second side surface 330 are planes. The second inclined surface 220 intersects with the second side surface 330.

[0061] It should be noted that, see Figure 3When the pot overflows, a large amount of liquid will spill out. The second inclined surface 220 can prevent the liquid from blocking the central ring flame hole 331. Since the protrusion 200 is located on the top of the outer flame cover body 100, some of the overflowing liquid will come into contact with the second inclined surface 220 on the protrusion 200, and the overflowing liquid will move under the guidance of the second inclined surface 220. Since the liquid has a certain speed, after the liquid leaves the second inclined surface 220, the trajectory of the liquid under the action of inertia and gravity is a parabolic trajectory. And the central ring flame hole 331 is located below the extension direction of the second inclined surface 220. The trajectory of the liquid is far away from the central ring flame hole 331 on the second side surface 330, thereby preventing the overflowing liquid from blocking the central ring flame hole 331.

[0062] Specifically, the channel 300 includes a third side 340 connected to the first side 110 and the second side 330. The protrusion 201 is provided with a third inclined surface 230 connected to the third side 340. The top of the third inclined surface 230 is inclined away from the channel 300 relative to the bottom of the third inclined surface 230. The top of the first inclined surface 210, the top of the second inclined surface 220 and the top of the third inclined surface 230 intersect at the apex of the protrusion 201.

[0063] In this embodiment, the first inclined surface 210, the second inclined surface 220 and the third inclined surface 230 form a structure similar to a triangular pyramid.

[0064] In one possible implementation, see Figure 2 A first arc surface 240 connects the first inclined surface 210 and the second inclined surface 220. The first arc surface 240 is connected to the first side surface 110. Both the first inclined surface 210 and the second inclined surface 220 are tangent to the first arc surface 240. A second arc surface 250 connects the second inclined surface 220 and the third inclined surface 230. The second arc surface 250 is connected to the second side surface 330. Both the second inclined surface 220 and the third inclined surface 230 are tangent to the second arc surface 250.

[0065] The first side surface 110, the second inclined surface 220, and the third inclined surface 230 are all planar surfaces. The first arc surface 240 and the second arc surface 250 are both arc surfaces.

[0066] It should be noted that during cleaning or disassembly, users' fingers can easily be accidentally scratched or cut by these sharp edges. By setting the first curved surface 240 and the second curved surface 250, this sharpness is completely eliminated. During the manufacturing process, the curved edges are less likely to produce burrs or are easier to handle compared to sharp edges.

[0067] In one possible implementation, the extending directions of two adjacent first side surfaces 110 intersect, and a connecting arc surface 400 connects the two adjacent first side surfaces 110.

[0068] Setting the connecting arc surface to 400 can further eliminate the sharpness of the edges.

[0069] Secondly, this utility model provides a burner, including the aforementioned outer flame cap.

[0070] The outer flame cap in this embodiment has the same structure as the outer flame cap 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.

[0071] Specifically, the burner also includes an inner flame cap 500, which is provided with an inner ring flame hole 510. The outer flame cap is provided with a through hole 101 that surrounds the inner flame cap 500. There is a gap between the outer flame cap and the inner flame cap 500. The outer flame cap is provided with an outer ring flame hole 120 and a middle ring flame hole 331. The outer ring flame hole 120 is located on the outer side wall of the outer flame cap. The middle ring flame hole 331 is located in the radial direction of the through hole 101 between the outer ring flame hole 120 and the inner ring flame hole 510.

[0072] It should be noted that the gas flows out through the inner ring flame hole 510, the middle ring flame hole 331 and the outer ring flame hole 120 and is ignited to form an inner ring flame, a middle ring flame and an outer ring flame. The inner ring flame is responsible for the concentrated heating of the central area of ​​the pot bottom, while the middle ring flame and the outer ring flame cover the middle and edge areas of the pot bottom. The inner ring flame, middle ring flame and outer ring flame 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.

[0073] In this embodiment, there are three flame patterns: the first pattern is that the outer ring flame hole 120, the middle ring flame hole 331, and the inner ring flame hole 510 all emit flame simultaneously; the second pattern is that the middle ring flame hole 331 and the inner ring flame hole 510 emit flame, while the outer ring flame hole 120 does not emit flame; and the third pattern is that only the inner ring flame hole 510 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; and the third pattern showed better uniformity on a saucepan, making it suitable for cooking scenarios such as simmering soup and cooking porridge.

[0074] Thirdly, such as Figure 4 As shown, 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] Fourthly, this utility model provides an integrated stove, including the stove described above.

[0077] The stove in this embodiment has the same structure as the stove 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.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
