Description

Technical Field

[0001] The present invention belongs to the technical field of burners, and particularly relates to a burner capable of achieving stable flame transfer and a gas stove using the same. Background Art

[0002] Traditional burners all include an inner-ring flame and an outer-ring flame. Their working principle is as follows: The gas first enters the inner fire cap to generate the inner-ring flame. Then, it is necessary to transfer the inner-ring flame to the outer fire cap through a flame-transfer hole or a flame-transfer groove, and then the inner-ring flame and the outer-ring flame are formed together for cooking.

[0003] However, due to the relatively large space of the current flame-transfer holes or flame-transfer grooves, the phenomenon of flame lift will occur during the flame-transfer process, resulting in unstable flames and thus flame-transfer failure. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a burner capable of achieving stable flame transfer, which solves the problem of easy flame-transfer failure in the prior art by setting a separate flame-transfer component.

[0005] Another object of the present invention is to provide a gas stove.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A burner capable of achieving stable flame transfer includes a burner head, an inner fire cap, an outer fire cap, a flame distributor, and a flame-transfer component. The flame distributor is arranged on the burner head, the inner fire cap is arranged inside the flame distributor, the outer fire cap is located above the flame distributor, and the flame-transfer component is arranged between the outer fire cap and the flame distributor.

[0008] Preferably, the flame-transfer component includes a first partition wall, a second partition wall, a notch, and a cavity. The upper ends of the first partition wall and the second partition wall both abut against the outer fire cap, the lower ends of the first partition wall and the second partition wall both abut against the flame distributor, and a cavity for accommodating gas is formed between the first partition wall and the second partition wall. At least two notches are provided and are respectively opened on the first partition wall and the second partition wall.

[0009] Preferably, the cavity is communicated with an outer fire hole provided on the circumferential surface of the outer fire cap.

[0010] Preferably, the first partition wall includes a first upper wall and a first lower wall. The upper end of the first upper wall is fixed to the outer fire cap, the lower end of the first upper wall is connected to the upper end of the first lower wall, the lower end of the first lower wall is connected to the flame distributor, and the notch opened on the first partition wall is located at the top of the first lower wall.

[0011] Preferably, the second partition wall includes a second upper wall and a second lower wall. The upper end of the second upper wall is fixed to the outer fire cover, the lower end of the second upper wall is connected to the upper end of the second lower wall, and the lower end of the second lower wall is connected to the burner. The notch formed in the second partition wall is located at the top of the second lower wall.

[0012] Preferably, the flame transmission component further includes a fire outlet formed in the outer fire cover above the cavity, and the fire outlet communicates with the cavity.

[0013] Preferably, the fire outlet also communicates with the outer fire hole through a drainage groove.

[0014] Preferably, the notch is circular, square or polygonal, and the width of the notch is not less than 0.2 mm.

[0015] Preferably, the notch is formed by machining with a mold.

[0016] A gas stove includes the above-mentioned burner and a gas stove body, and the burner is connected to the gas stove body.

[0017] Compared with the prior art, when the burner in the present invention works, gas enters the burner through the stove head. Part of the gas in the burner enters the inner fire cover to form an inner ring fire, and part of the gas also enters the outer fire cover through the flame transmission component to prepare in advance for the formation of the outer ring fire;

[0018] Since the gas enters the outer fire cover through the flame transmission component, and the flame transmission component is an independent structure, it can control the gas volume, optimize the flow rate and flow volume of the transmitted gas, and reduce the problem of flame transmission failure caused by easy flame separation in traditional flame transmission holes or flame transmission grooves.

[0028] Embodiment 1

[0029] Embodiment 1 of the present invention provides a burner that can achieve stable fire transfer, as Figure 1 and Figure 2 shown. It includes a burner head 1, an inner fire cover 2, an outer fire cover 3, a flame divider 4, and a fire transfer component 5. The flame divider 4 is arranged on the burner head 1. The inner fire cover 2 is arranged inside the flame divider 4. The outer fire cover 3 is located above the flame divider 4. The fire transfer component 5 is arranged between the outer fire cover 3 and the flame divider 4;

[0030] In this way, with the above structure, when the burner is working, the gas enters the fire divider 4 through the burner head 1. Part of the gas in the fire divider 4 enters the inner fire cap 2 to form an inner ring fire, and part of the gas enters the outer fire cap 3 through the fire transfer component 5 to prepare in advance for the formation of the outer ring fire. Since the gas enters the outer fire cap 3 through the fire transfer component 5, and the fire transfer component 5 is an independent structure, it can control the gas volume, optimize the flow rate and flow volume of the fire transfer gas, and reduce the problem of fire transfer failure caused by the easy occurrence of flame lift in traditional fire transfer holes or fire transfer grooves.

[0031] In a specific embodiment, as Figure 1-3 shown, the fire transfer component 5 includes a first partition wall 51, a second partition wall 52, a notch 53 and a cavity 54. The upper ends of the first partition wall 51 and the second partition wall 52 are both abutted against the outer fire cap 3, and the lower ends of the first partition wall 51 and the second partition wall 52 are both abutted against the fire divider 4. A cavity 54 for accommodating gas is formed between the first partition wall 51 and the second partition wall 52. At least two notches 53 are provided and are respectively opened on the first partition wall 51 and the second partition wall 52;

[0032] In this way, when the gas enters the fire divider 4 through the burner head 1, the gas for fire transfer enters the cavity 54 formed by the first partition wall 51 and the second partition wall 52 through the notch 53;

[0033] Due to the existence of the notch 53 and the cavity 54, the amount of the gas for fire transfer is effectively controlled, the flow rate and flow volume of the fire transfer gas are optimized, and the problem of poor fire transfer caused by flame lift is avoided.

[0034] In addition, the cavity 54 is communicated with the outer fire holes 31 provided on the circumferential surface of the outer fire cap 3;

[0035] In this way, the gas for fire transfer in the cavity 54 can be directly transferred to the outer fire holes 31, which is convenient for transferring the inner ring fire to the outer fire cap 3.

[0036] In one of the embodiments, the first partition wall 51 includes a first upper wall 511 and a first lower wall 512. The upper end of the first upper wall 511 is fixed to the outer fire cap 3, the lower end of the first upper wall 511 is connected to the upper end of the first lower wall 512, and the lower end of the first lower wall 512 is connected to the fire divider 4. The notch 53 opened on the first partition wall 51 is located at the top of the first lower wall 512;

[0037] And specifically, in order to reduce the number of components in the burner and make the burner easier to process, the first upper wall 511 is integrally formed with the outer fire cap 3, and the first lower wall 512 is integrally formed with the fire divider 4.

[0038] The second partition wall 52 includes a second upper wall 521 and a second lower wall 522. The upper end of the second upper wall 521 is fixed to the outer fire cap 3. The lower end of the second upper wall 521 is connected to the upper end of the second lower wall 522. The lower end of the second lower wall 522 is connected to the burner head 4. The notch 53 formed in the second partition wall 52 is located at the top of the second lower wall 522.

[0039] Moreover, specifically, in order to reduce the number of components in the burner and make the burner easier to process, the second upper wall 521 is integrally formed with the outer fire cap 3, and the second lower wall 522 is integrally formed with the burner head 4.

[0040] In addition, in order not to increase the difficulty of mating between the burner head 4 and the outer fire cap 3, the lower ends of the first upper wall 511 and the second upper wall 521 are flush with the lower end of the outer fire cap 3. When the burner head 4 is mated with the outer fire cap 3, the upper end of the first lower wall 512 and the upper end of the second lower wall 522 just contact the bottom of the first upper wall 511 and the bottom of the second upper wall 521, so that the first upper wall 511, the first lower wall 512, the second upper wall 521 and the second lower wall 522 cooperate together to form a cavity 54.

[0041] Moreover, the notch 53 is formed at the top of the first lower wall 512 and the second lower wall 522, rather than in the middle; in this way, the processing of the notch 53 can be more convenient.

[0042] The notch 53 is formed by a mold. Of course, it can also be formed by machining.

[0043] In addition, the notch 53 can be circular, square or polygonal, but is not limited to the above shapes.

[0044] In order to ensure that the gas for flame transfer can smoothly flow from the burner head 4 into the cavity 54, the width of the notch 53 is not less than 0.2 mm.

[0045] In another embodiment, as Figure 4 and Figure 5 shown, the flame transfer assembly 5 further includes a fire outlet hole 55 formed in the outer fire cap 3 above the cavity 54. The fire outlet hole 54 is communicated with the cavity 54; the fire outlet hole 54 is also communicated with the outer fire hole 31 through a drainage groove 56.

[0046] In this way, the gas is drained to the surface of the outer fire cap 3 through the fire outlet hole 55, and then drained to the outer fire hole 31 through the drainage groove 56, so that the area covered by the gas for flame transfer is wider, and the success rate of flame transfer is higher.

[0047] Specifically, there are at least two flame outlets 55. One of the flame outlets 55 is communicated with the drainage groove 56 for guiding the gas to the outer flame holes 31, and the remaining flame outlets 55 are used to distribute the gas on the surface of the outer fire cap 3.

[0048] The working process of the burner provided in this embodiment is as follows:

[0049] After the burner starts to work, the gas is ejected upward through the burner head 1 to the gas distributor 4. When at the gas distributor 4, part of the gas flows into the cavity 54 formed by the cooperation of the first upper wall 511, the first lower wall 512, the second upper wall 521 and the second lower wall 522 through the notch 53. Part of the gas in the cavity 54 is directly transmitted to the outer flame holes 31, and the other part is guided to the surface of the outer fire cap 3 through the flame outlets 55, and then is guided to the outer flame holes 31 through the drainage groove 56. In this way, the gas for flame transmission covers a larger area of the outer fire cap 3, making the success rate of flame transmission higher.

[0050] In this embodiment, part of the gas is separated through the notch for flame transmission. The separated gas is located in an independent cavity, so that the gas volume can be controlled, the flow rate and flow volume of the gas for flame transmission can be optimized, and the problem of flame transmission failure caused by easy flame lift of traditional flame transmission holes or flame transmission grooves can be reduced; and the separated gas is distributed on the outer fire cap through the cooperation of the flame outlet, the drainage groove and the outer flame hole, further improving the success rate of flame transmission.

[0051] Embodiment 2

[0052] Embodiment 2 of the present invention provides a gas stove, which includes the burner described in Embodiment 1 and a gas stove body, and the burner is connected to the gas stove body.

[0053] In this embodiment, by applying the burner that can achieve stable flame transmission to the gas stove, the success rate of flame transmission of the gas stove is increased, the user experience is improved, and it can be achieved by adding simple components, with low cost and easy to promote.

[0054] The above is only a specific and preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
