Description

Technical Field

[0001] The utility model relates to the technical field of stoves, in particular to a burner and a gas stove. Background Art

[0002] A gas stove refers to a kitchen appliance that uses gas fuels such as liquefied petroleum gas, artificial gas, and natural gas for direct flame heating.

[0003] Gas stoves are typically equipped with a burner, where gas fuel is burned to heat cookware placed on the stove, meeting the user's cooking needs. A burner generally includes a burner base and a fire cover assembly mounted on the burner base. The fire cover assembly includes an outer ring fire cover and an inner ring fire cover. The air outlet of the outer ring ejector pipe mounted on the burner base is connected to the outer ring air inlet of the outer ring fire cover, allowing gas to be transported to the outer ring fire cover for combustion, forming an outer ring fire. The air outlet of the inner ring ejector pipe mounted on the burner base is connected to the inner ring air inlet of the inner ring fire cover, allowing gas to be transported to the inner ring fire cover for combustion, forming an inner ring fire.

[0004] When users want to cook food at high heat, they usually adjust the gas valve of the gas stove so that both the outer and inner ring flames are at maximum. However, when users cook a large amount of food at a time, or want to stir-fry with higher heat, even if both the outer and inner ring flames are adjusted to maximum, it still cannot meet the user's stir-fry needs. Utility Model Content

[0005] One of the technical problems solved by the present invention is to provide a burner which can effectively solve the technical problem that the burners of gas stoves in the prior art are difficult to meet the stir-frying needs of users.

[0006] The second technical problem solved by the present invention is to provide a gas stove, which can effectively solve the technical problem that the burner of the gas stove in the prior art is difficult to meet the user's demand for stir-frying.

[0007] The first technical problem mentioned above is solved by the following technical solution:

[0008] Burner, including:

[0009] A burner base, wherein the burner base is provided with an outer ring ejector tube, an inner ring ejector tube, a stir-fry ejector tube and a stir-fry ejector tube protection cavity, and the stir-fry ejector tube is arranged through the stir-fry ejector tube protection cavity;

[0010] A fire cover assembly is arranged on the burner base, and the fire cover assembly includes an outer ring fire cover and an inner ring fire cover arranged coaxially. The outlet end of the outer ring ejector tube is connected to the outer ring fire cover, and the outlet end of the inner ring ejector tube is connected to the inner ring fire cover.

[0011] Compared with the background technology, the burner of the present invention has the following beneficial effects:

[0012] Under normal circumstances, the burner uses the outer ring ejector tube to supply gas for combustion to the outer ring fire cover, and the inner ring ejector tube to supply gas for combustion to the inner ring fire cover. At this time, the working state of the burner is consistent with that of the burner in the prior art. When the user wants to use the stir-fry mode for cooking, while maintaining the outer ring ejector tube and the inner ring ejector tube to supply gas to the fire cover assembly, the stir-fry ejector tube is controlled to supply gas at the same time. Since the inner ring fire cover gathers heat inward, the flame burning at the inner ring fire cover will also ignite the gas from the stir-fry ejector tube in the inner ring of the inner ring fire cover. This is equivalent to the outer ring fire at the outer ring fire cover, the inner ring fire at the inner ring fire cover, and the center fire located at the inner ring of the inner ring fire cover, thereby fully meeting the user's stir-fry cooking needs.

[0013] In one embodiment, there is a first air intake gap between the inner ring surface of the inner ring fire cover and the outer peripheral surface of the stir-fry ejector tube, and a second air intake gap connected to the first air intake gap is formed between the outer wall of the stir-fry ejector tube and the inner wall of the stir-fry ejector tube protection cavity, and the second air intake gap is a vertical through-structure.

[0014] In one embodiment, the upper end opening of the inner ring of the inner ring fire cover is a flared structure.

[0015] In one embodiment, the stir-frying ejector tube includes a first pipe section and a second pipe section. The first pipe section is arranged along the axial direction of the inner ring fire cover and the upper end is located within the inner circle of the inner ring fire cover. The second pipe section is arranged at an angle to the lower end of the first pipe section.

[0016] In one embodiment, the air outlet end of the stir-fry ejector tube is not lower than the upper end surface of the inner ring fire cover.

[0017] In one embodiment, the fire holes of the inner ring fire cover are arranged on the outer peripheral surface of the inner ring fire cover, and the inner peripheral surface of the inner ring fire cover is a solid structure.

[0018] In one embodiment, the stir-fry ejector tube is provided with a connecting ear that can be connected to the burner base.

[0019] The second technical problem mentioned above is solved by the following technical solution:

[0020] A gas stove comprising the burner mentioned above.

[0021] Compared with the background technology, the gas stove of the present invention has the following beneficial effects:

[0022] The gas stove includes the above-mentioned burner. When the user uses the gas stove for cooking, generally, the outer ring ejector tube supplies gas to the outer ring fire cover for combustion, and the inner ring ejector tube supplies gas to the inner ring fire cover for combustion. At this time, the working state of the burner is consistent with that of the burner in the prior art. When the user wants to use the stir-fry mode for cooking, while keeping the outer ring ejector tube and the inner ring ejector tube supplying gas to the fire cover assembly, the stir-fry ejector tube is controlled to supply gas at the same time. Since the inner ring fire cover gathers heat inward, the flame burning at the inner ring fire cover will also ignite the gas from the stir-fry ejector tube in the inner ring of the inner ring fire cover. This is equivalent to the outer ring fire at the outer ring fire cover, the inner ring fire at the inner ring fire cover, and the center fire located at the inner ring of the inner ring fire cover, thereby fully meeting the user's stir-fry cooking needs.

[0023] In one embodiment, the stir-fry ejector tube includes a first tube section and a second tube section, the first tube section is arranged along the axial direction of the inner ring fire cover and the upper end is located within the inner circle of the inner ring fire cover, the second tube section is arranged at an angle to the lower end of the first tube section, and the gas stove further includes a nozzle, which is arranged opposite to the inlet end of the second tube section;

[0024] The inlet end of the second pipe section is a flared structure.

[0025] In one embodiment, the gas stove further includes a nozzle and a nozzle air supply pipe, the nozzle is arranged at the outlet end of the nozzle air supply pipe, and the nozzle is arranged opposite to the inlet end of the stir-frying ejector pipe.

[0049] Example 1

[0050] This embodiment provides a burner that can be used on a gas stove and can meet both the user's general cooking needs and the user's high-fire stir-fry cooking needs.

[0051] Specifically, see Figures 1-4 In this embodiment, the burner includes a burner base 10 and a fire cover assembly 20.

[0052] The burner base 10 is provided with an outer ring ejector tube 101, an inner ring ejector tube 102, a stir-fry ejector tube 103, and a stir-fry ejector tube protection cavity 104. The stir-fry ejector tube 103 is provided through the stir-fry ejector tube protection cavity 104. Specifically, the stir-fry ejector tube protection cavity 104 is coaxially arranged with the inner ring of the inner ring fire cover 202.

[0053] The fire cover assembly 20 is arranged on the burner base 10, and the fire cover assembly 20 includes an outer ring fire cover 201 and an inner ring fire cover 202 arranged coaxially. The outlet end of the outer ring ejector tube 101 is connected to the outer ring fire cover 201, and the outlet end of the inner ring ejector tube 102 is connected to the inner ring fire cover 202.

[0054] The burner provided in this embodiment, under normal circumstances, is operated by the outer ring ejector tube 101 to supply gas for combustion to the outer ring fire cover 201, and by the inner ring ejector tube 102 to supply gas for combustion to the inner ring fire cover 202. At this time, the working state of the burner is consistent with that of the burner in the prior art. When the user wants to use the stir-fry mode for cooking, while maintaining the outer ring ejector tube 101 and the inner ring ejector tube 102 to supply gas to the fire cover assembly 20, the stir-fry ejector tube 103 is controlled to supply gas at the same time. Since the inner ring fire cover 202 gathers heat inward, the flame burning at the inner ring fire cover 202 will also ignite the gas from the stir-fry ejector tube in the inner ring of the inner ring fire cover 202. This is equivalent to the outer ring fire at the outer ring fire cover 201, the inner ring fire at the inner ring fire cover 202, and the center fire at the inner ring of the inner ring fire cover 202, thereby fully meeting the user's stir-fry cooking needs.

[0055] In the burner, the setting of the stir-frying ejector tube 103 forms a stir-frying ejector cavity 1034, which fully ensures that the gas flows along the stir-frying ejector cavity 1034 to the inner circle of the inner ring fire cover 202 and participates in the combustion, forming a stable stir-frying center fire.

[0056] It should be noted that when this burner is used in a gas stove, a valve knob is provided on the stove panel to control the outer and inner flames. Adjusting the valve knob can achieve synchronous regulation of the outer and inner flames. This function is a prior art and will not be described in detail here.

[0057] Furthermore, in one embodiment, the fire holes of the inner ring fire cover 202 are disposed on the outer circumference of the inner ring fire cover 202, and the inner circumference of the inner ring fire cover 202 is a solid structure. That is, the fire holes of the inner ring fire cover 202 are disposed on the outer circumference of the inner ring fire cover 202, and no fire holes are disposed on the inner ring of the inner ring fire cover 202. If fire holes were disposed on the inner ring of the inner ring fire cover 202, insufficient secondary air would be supplied to the fire holes, resulting in incomplete combustion of the gas there, and smoke explosions would occur.

[0058] In one embodiment, the air outlet end of the stir-fry ejector tube 103 is not lower than the upper end surface of the inner ring fire cover 202. That is, the air outlet end of the stir-fry ejector tube 103 is flush with or higher than the upper end surface of the inner ring fire cover 202. This arrangement allows the secondary air at the air outlet end of the stir-fry ejector tube 103 to be more fully replenished, and the flame at the air outlet end of the stir-fry ejector tube 103 will not separate from the flame. If the air outlet end of the stir-fry ejector tube 103 is lower than the upper end surface of the inner ring fire cover 202, the air at the air outlet end of the stir-fry ejector tube 103 may be insufficient, affecting the normal combustion of the flame there, and further affecting the user's stir-frying experience.

[0059] Furthermore, the air outlet end of the stir-frying ejector tube 103 is slightly higher than the upper end surface of the inner ring fire cover 202, which can not only ensure that the secondary air at the air outlet end of the stir-frying ejector tube 103 is more fully replenished, but also avoid interference between the air outlet end of the stir-frying ejector tube 103 and the cookware.

[0060] In one embodiment, see Figure 2 and Figure 4 There is a first air intake gap 2021 between the inner ring surface of the inner ring fire cover 202 and the outer peripheral surface of the stir-frying ejector tube 103, and a second air intake gap connected to the first air intake gap 2021 is formed between the outer wall of the stir-frying ejector tube 103 and the inner wall of the stir-frying ejector tube protection cavity 104. The second air intake gap is a vertical through structure.

[0061] The existence of the first air intake gap 2021 and the second air intake gap allows the outside air to flow along the second air intake gap and the first air intake gap 2021 in sequence to the outlet end of the stir-fry ejector tube 103. At the outlet end of the stir-fry ejector tube 103, the outside air is mixed with the gas to form a combustible mixture, thereby ensuring the stable combustion of the flame at the outlet end of the stir-fry ejector tube 103, and ultimately ensuring the user's stir-fry cooking needs.

[0062] Furthermore, in one embodiment, the upper end opening of the inner ring of the inner ring flame cover 202 is flared. This configuration makes the inlet end of the first air inlet gap 2021 larger, allowing sufficient ambient air to be introduced into the first air inlet gap 2021, ensuring stable combustion of the flame at the outlet end of the stir-fry ejector tube 103.

[0063] Further, see Figure 5 and Figure 6 In one embodiment, the stir-frying ejector tube 103 includes a first tube section 1031 and a second tube section 1032. The first tube section 1031 is arranged along the axial direction of the inner ring fire cover 202 and the upper end is located in the inner circle of the inner ring fire cover 202. The second tube section 1032 is arranged at an angle to the lower end of the first tube section 1031.

[0064] The first pipe section 1031 is disposed through the stir-fry ejector tube protection cavity 104 .

[0065] When the burner is used on a gas stove, it is generally necessary to respectively set up separate gas supply paths for the outer ring ejector tube 101 , the inner ring ejector tube 102 and the stir-fry ejector tube 103 .

[0066] The air supply paths of the outer ring ejector tube 101 and the inner ring ejector tube 102 belong to the prior art and will not be described in detail here.

[0067] Specifically, see Figure 12 and Figure 13 When setting up an air supply circuit for the stir-fry ejector tube 103, a nozzle 100 is provided at the output end of the air supply circuit for the stir-fry ejector tube. The nozzle 100 ejects air toward the end of the second pipe section 1032 away from the first pipe section 1031, thereby supplying air to the stir-fry ejector tube 103. Since the second pipe section 1032 is arranged at an angle to the lower end of the first pipe section 1031, the nozzle 100 does not need to be arranged directly opposite the center of the inner ring of the inner ring fire cover 202, that is, the nozzle 100 does not need to be located directly below the inner ring of the inner ring fire cover 202. In this way, foreign matter falling from the inner ring of the inner ring fire cover 202 into the stir-fry ejector tube 103 can be prevented from blocking the nozzle 100, thereby ensuring the normal combustion of the flame at the outlet end of the stir-fry ejector tube 103.

[0068] Optionally, the nozzle 100 has a size of 0.4 mm to 0.6 mm, and further, the nozzle 100 has a size of 0.6 mm. The nozzle's heat load can be 300 W to 400 W, and further, 300 W, 350 W, or 400 W, preferably 350 W. If the nozzle is too large and the secondary air supply is insufficient, flame lift is likely to occur in the combustion section of the stir-fry ejector tube 103.

[0069] Furthermore, in one embodiment, the inlet end of the second pipe section 1032 is a flared structure.

[0070] The inlet end of the second pipe section 1032 is set to a flared structure. When the nozzle 100 sprays gas toward the inlet end of the second pipe section 1032, the air around the inlet end of the second pipe section 1032 will also enter the second pipe section 1032 from the inlet end of the second pipe section 1032. With this arrangement, the gas entering the stir-fry ejector tube 103 is a mixture of gas and air. After the mixture flows to the outlet end of the stir-fry ejector tube 103, it can be directly ignited to form a stable stir-fry center fire. The stir-fry center fire, outer ring fire and inner ring fire work together to fully guarantee the user's stir-fry cooking needs.

[0071] Further, see Figure 5 and Figure 6The second pipe section 1032 includes a curved pipe portion 10321 and a straight pipe portion 10322. The curved pipe portion 10321 is connected between the straight pipe portion 10322 and the first pipe section 1031. The open end of the straight pipe portion 10322 is a flared structure.

[0072] Specifically, the flared structure is a trumpet structure.

[0073] Further, see Figure 3-Figure 5 In one embodiment, the stir-fry ejector tube 103 is provided with a connecting ear 1033 that can be connected to the burner base 10.

[0074] Specifically, a connecting ear 1033 is provided on opposite sides of the bend portion 10321, and each connecting ear 1033 is mounted on the burner base 10 through a connecting member 30. Optionally, the connecting member 30 is a screw.

[0075] Further, see Figure 4 、 Figure 7 and Figure 8 In one embodiment, the outer ring ejector tube 101 and the inner ring ejector tube 102 are integrally formed on the burner base 10 .

[0076] An outer ring gas guide channel 105 and an inner ring gas guide channel 106 are provided in the burner base 10 , which are independent of each other. The outer ring ejector tube 101 is connected to the outer ring gas guide channel 105 , and the inner ring ejector tube 102 is connected to the inner ring gas guide channel 106 .

[0077] Specifically, taking the actual use orientation of the burner as an example, the outer ring ejector tube 101 is connected to the lower end of the outer ring gas guide channel 105 , and the inner ring ejector tube 102 is connected to the lower end of the inner ring gas guide channel 106 .

[0078] An outer ring air channel 2011 is provided in the outer ring fire cover 201, and the outlet end of the outer ring air channel 105 is communicated with the outer ring air channel 2011. An inner ring air channel 2022 is provided in the inner ring fire cover 202, and the outlet end of the inner ring air channel 106 is communicated with the inner ring air channel 2022.

[0079] Specifically, taking the actual use orientation of the burner as an example, the outlet end of the outer ring air guide channel 105 is located at the upper end of the outer ring air guide channel 105 , and the outlet end of the inner ring air guide channel 106 is located at the upper end of the inner ring air guide channel 106 .

[0080] Specifically, the fuel gas enters the outer ring gas channel 2011 through the outer ring ejector pipe 101 and the outer ring gas guide channel 105 in sequence; the fuel gas enters the inner ring gas channel 2022 through the inner ring ejector pipe 102 and the inner ring gas guide channel 106 in sequence.

[0081] Example 2

[0082] See also Figures 9-12 , this embodiment provides a gas stove, which includes the burner of embodiment one.

[0083] Optionally, the gas stove can be a single-burner gas stove, with one of the burners above being provided at the burner. Alternatively, it can be a double-burner gas stove, with each of the burners above being provided with a burner above, or one of the burners being provided with the burner above and the other being a common burner.

[0084] Since the gas stove includes the burner of the embodiment, the gas stove can fully meet the stir-fry cooking needs of the user.

[0085] When using the gas stove to cook food, under normal circumstances, the outer ring ejector tube 101 supplies gas to the outer ring fire cover 201 for combustion, and the inner ring ejector tube 102 supplies gas to the inner ring fire cover 202 for combustion. At this time, the working state of the burner is consistent with that of the burner in the prior art. When the user wants to use the stir-fry mode for cooking, while keeping the outer ring ejector tube 101 and the inner ring ejector tube 102 supplying gas to the fire cover assembly 20, the stir-fry ejector tube 103 is controlled to supply gas at the same time. Since the outlet end of the stir-fry ejector tube 103 is located in the inner ring of the inner ring fire cover 202, the flame burning at the inner ring fire cover 202 will also ignite the inner ring of the inner ring fire cover 202, which is equivalent to the outer ring fire at the outer ring fire cover 201, the inner ring fire at the inner ring fire cover 202, and the center fire located at the inner ring of the inner ring fire cover 202, thereby fully meeting the user's stir-fry cooking needs.

[0086] The setting of the stir-frying ejector tube 103 in the burner forms a stir-frying ejector cavity 1034, which fully ensures that the gas flows along the stir-frying ejector cavity 1034 to the inner circle of the inner ring fire cover 202 and participates in combustion, forming a stable stir-frying center fire.

[0087] Specifically, in one embodiment, see Figure 5 、 Figure 6 、 Figure 11-13 The stir-frying ejector tube 103 includes a first pipe section 1031 and a second pipe section 1032. The first pipe section 1031 is arranged along the axial direction of the inner ring fire cover 202 and the upper end is located in the inner circle of the inner ring fire cover 202. The second pipe section 1032 is arranged at an angle to the lower end of the first pipe section 1031. The gas stove also includes a nozzle 100, which is arranged opposite to the inlet end of the second pipe section 1032.

[0088] When the burner is used on a gas stove, it is generally necessary to respectively set up separate gas supply paths for the outer ring ejector tube 101 , the inner ring ejector tube 102 and the stir-fry ejector tube 103 .

[0089] Specifically, see Figure 12 and Figure 13When setting up an air supply circuit for the stir-fry ejector tube 103, a nozzle 100 is installed at the output end of the air supply circuit. The nozzle 100 sprays air toward the end of the second pipe section 1032 that is away from the first pipe section 1031, thereby supplying air to the stir-fry ejector tube 103. Because the second pipe section 1032 is connected to the lower end of the first pipe section 1031 at an angle, the nozzle 100 does not need to be directly aligned with the center of the inner ring of the inner ring fire cover 202. This prevents foreign matter from falling from the inner ring of the inner ring fire cover 202 into the stir-fry ejector tube 103 and blocking the nozzle 100, thus ensuring the normal combustion of the flame at the outlet end of the stir-fry ejector tube 103.

[0090] Example 3

[0091] See also Figures 9-12 , this embodiment provides a gas stove, which includes the burner of embodiment one.

[0092] Optionally, the gas stove can be a single-burner gas stove with one of the above-mentioned burners provided at the burner. It can also be a double-burner gas stove with one of the burners provided at each burner, or one of the burners provided with the above-mentioned burner and the other provided with a common burner.

[0093] Since the gas stove includes the burner of the embodiment, the gas stove can fully meet the stir-fry cooking needs of the user.

[0094] When using the gas stove to cook food, under normal circumstances, the outer ring ejector tube 101 supplies gas to the outer ring fire cover 201 for combustion, and the inner ring ejector tube 102 supplies gas to the inner ring fire cover 202 for combustion. At this time, the working state of the burner is consistent with that of the burner in the prior art. When the user wants to use the stir-fry mode for cooking, while keeping the outer ring ejector tube 101 and the inner ring ejector tube 102 supplying gas to the fire cover assembly 20, the stir-fry ejector tube 103 is controlled to supply gas at the same time. Since the outlet end of the stir-fry ejector tube 103 is located in the inner ring of the inner ring fire cover 202, the flame burning at the inner ring fire cover 202 will also ignite the inner ring of the inner ring fire cover 202, which is equivalent to the outer ring fire at the outer ring fire cover 201, the inner ring fire at the inner ring fire cover 202, and the center fire located at the inner ring of the inner ring fire cover 202, thereby fully meeting the user's stir-fry cooking needs.

[0095] The setting of the stir-frying ejector tube 103 in the burner forms a stir-frying ejector cavity 1034, which fully ensures that the gas flows along the stir-frying ejector cavity 1034 to the inner circle of the inner ring fire cover 202 and participates in combustion, forming a stable stir-frying center fire.

[0096] Further, see Figure 10-13In one embodiment, the gas stove further includes a nozzle 100 and a nozzle air supply pipe 200 , the nozzle 100 is arranged at the outlet end of the nozzle air supply pipe 200 , and the nozzle 100 is arranged opposite to the inlet end of the stir-frying injection pipe 103 .

[0097] Gas is sprayed into the inlet end of the stir-fry ejector tube 103 from the nozzle 100 to realize gas supply to the stir-fry ejector tube 103 .

[0098] Furthermore, the gas stove also includes a nozzle gas supply pipe control valve, which controls the on / off state of the nozzle gas supply pipe 200. Specifically, the nozzle gas supply pipe control valve is installed on the nozzle gas supply pipe 200 and passes through the panel of the gas stove, making it convenient for users to operate the nozzle gas supply pipe control valve.

[0099] Further, see Figure 5 、 Figure 6 、 Figure 11-13 The stir-fry ejector tube 103 includes a first tube section 1031 and a second tube section 1032. The first tube section 1031 is arranged along the axial direction of the inner ring fire cover 202, with its upper end located within the inner ring of the inner ring fire cover 202. The second tube section 1032 is arranged at an angle to the lower end of the first tube section 1031. The gas stove also includes a nozzle 100, which is arranged directly opposite the inlet end of the second tube section 1032. This arrangement can prevent foreign matter from falling from the inner ring of the inner ring fire cover 202 into the stir-fry ejector tube 103 and blocking the nozzle 100, ensuring the normal combustion of the flame at the outlet end of the stir-fry ejector tube 103.

[0100] Further, in one embodiment, see Figure 13 The gas stove further includes a nozzle mounting seat 300 , and the nozzle 100 is fixedly mounted on the nozzle mounting seat 300 .

[0101] The presence of the nozzle mounting seat 300 enables the nozzle 100 to be stably mounted, thereby achieving a stable air supply to the stir-fry ejector tube 103 .
