Description

Technical Field

[0001] This utility model relates to the field of gas stove burner technology, and in particular to a gas stove burner with a dual-channel gas distribution structure. Background Technology

[0002] The gas stove burner is the core functional component of a gas stove. Installed on the cooktop, it's responsible for mixing gas (natural gas, liquefied petroleum gas, or manufactured gas) with air, igniting it, and ensuring stable combustion to produce a flame for heating the cookware. Existing gas stove burners mainly consist of a gas distribution plate and a burner cap covering the plate. The distribution plate has an outer flame gas passage and an inner flame gas passage. The outer flame gas passage connects to both the external air intake pipe and the inner flame gas passage. Gas flows from the external air intake pipe into the outer flame gas passage and then into the inner flame gas passage. Because the outer and inner flame gas passages are interconnected, they restrict each other, resulting in limited flame adjustment flexibility. Utility Model Content

[0003] The purpose of this utility model is to provide a gas stove burner head with a dual-channel gas distribution structure to solve the problems of existing gas stove burner heads where the outer flame gas channel and inner flame gas channel are interconnected, the outer flame gas channel and inner flame gas channel restrict each other, and the flame adjustment flexibility is not good.

[0004] This utility model is achieved through the following technical solution:

[0005] A gas stove burner head with a dual-channel gas distribution structure includes a gas distribution plate. The gas distribution plate has an inner gas channel, an outer gas channel, an inner air inlet, and an outer air inlet. The inner gas channel and the outer gas channel are independent of each other, and the inner air inlet and the outer air inlet are independent of each other. The inner air inlet is connected to the inner gas channel, and the outer air inlet is connected to the outer gas channel. The inner gas channel has a central branch channel that extends vertically and opens upward. The outer gas channel has an outer ring branch channel that surrounds the central branch channel and opens upward.

[0006] Furthermore, the external air duct also has an external inlet branch and a distribution branch. The external inlet branch is connected to the external air inlet and is located below the outer ring branch. The distribution branch extends circumferentially around the distribution plate and is connected to the external inlet branch and the outer ring branch respectively.

[0007] Furthermore, the internal air passage also has an internal inlet branch, one end of which is connected to the central branch, and the other end forms the internal air inlet.

[0008] Furthermore, the inner intake branch extends radially along the air distribution plate and is located at the lower end of the central branch, the outer intake branch extends radially along the air distribution plate and is arranged side by side with the inner intake branch, and the inner air inlet and the outer air inlet are arranged side by side.

[0009] Furthermore, the air distribution plate includes an upper plate and a lower plate, which are stacked one on top of the other to form the inner air passage and the outer air passage, and the upper plate and the lower plate are detachably and fixedly connected.

[0010] Furthermore, the upper plate is provided with an upper support channel, and the lower plate is provided with a lower support channel. The upper support channel and the lower support channel are arranged vertically to form the central support channel. The upper plate has a positioning ring that extends from the lower end of the upper support channel into the lower support channel. The inner wall of the lower support channel is provided with a locking strip that extends vertically. The positioning ring is provided with a slot for the locking strip to be inserted.

[0011] Furthermore, the upper plate is provided with the outer ring branch channel, and the lower plate is provided with the outer inlet branch channel, the air distribution branch channel, and the inner inlet branch channel.

[0012] Furthermore, there are two air distribution branches, which extend circumferentially around the air distribution plate and are arranged opposite each other in the radial direction of the air distribution plate. One end of the external inlet branch is connected to the two air distribution branches, and the other end forms the external air inlet.

[0013] Furthermore, the two gas distribution branches are connected at the end of the outer intake branch away from the outer air inlet. The length direction of the outer intake branch is defined as the front-to-back direction. The lower plate has a base shell and a rear cover. The base shell and the rear cover are arranged front to back to form the outer intake branch and the gas distribution branch. The rear cover is riveted to the base shell.

[0014] Furthermore, it also includes an inner flame cap and an outer flame cap.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figure 1-7 As shown, the gas stove burner head with a dual-channel gas distribution structure includes a gas distribution plate 1. The gas distribution plate 1 has an inner gas channel 101, an outer gas channel 102, an inner air inlet 103, and an outer air inlet 104. The inner gas channel 101 and the outer gas channel 102 are independent of each other, as are the inner air inlet 103 and the outer air inlet 104. The inner air inlet 103 is connected to the inner gas channel 101, and the outer air inlet 104 is connected to the outer gas channel 102. The inner gas channel 101 has a central branch channel 105, which extends vertically and opens upward. The outer gas channel 102 has an outer ring branch channel 106, which surrounds the central branch channel 105 and opens upward. The axial direction of the gas distribution plate 1 is defined as the vertical direction.

[0027] It also includes an inner flame cap 2 and an outer flame cap 3. The inner flame cap 2 is installed at the opening of the central branch channel 105 and surrounds the gas distribution plate 1 to form a number of inner flame ports 4. The number of inner flame ports 4 are spaced apart in the circumference of the central branch channel 105. The outer flame cap 3 is installed at the opening of the outer ring branch channel 106 and surrounds the gas distribution plate 1 to form a number of outer flame ports 5. The number of outer flame ports 5 are spaced apart in the circumference of the outer ring branch channel 106. The gas distribution plate 1 is equipped with an inner igniter 6 and an outer igniter 7. The inner igniter 6 is located on one side of the central branch channel 105, and the outer igniter 7 is located on one side of the outer ring branch channel 106.

[0028] The external air inlet 104 is used to connect with the external air intake pipe. After the gas enters the external air passage 102 from the external air intake pipe, it flows into the outer ring branch 106 and is ignited by the external igniter 7 to form an outer flame at the outer flame port 5. The internal air inlet 103 is used to connect with the external air intake pipe. After the gas enters the internal air passage 101 from the external air intake pipe, it flows into the central branch 105 and is ignited by the internal igniter 6 to form an inner flame at the inner flame port 4.

[0029] In summary, this embodiment provides a gas stove burner with a dual-channel gas distribution structure to solve the problems of interconnected outer and inner flame gas channels in existing gas stove burners, mutual constraints between the outer and inner flame gas channels, and poor flame adjustment flexibility. This is mainly achieved by configuring independent inner gas channels 101 and outer gas channels 102 on the gas distribution plate 1. The inner gas channel 101 has a central branch channel 105 that extends vertically and opens upward, and the outer gas channel 102 has an outer ring branch channel 106 that is arranged around the central branch channel 105 and opens upward. This ensures that the air intake of the inner gas channel 101 that forms the inner flame and the outer gas channel 102 that forms the outer flame are independent and do not interfere with each other, resulting in flexible and versatile flame adjustment and convenient use.

[0030] In this embodiment of the invention, the external air duct 102 further includes an external inlet branch 107 and a gas distribution branch 108. One end of the external inlet branch 107 has an external air inlet 104 located below the outer ring branch 106. The gas distribution branch 108 extends circumferentially around the gas distribution plate 1 and communicates with both the external inlet branch 107 and the outer ring branch 106. This arrangement, by configuring the external inlet branch 107 with an external air inlet 104 at one end below the outer ring branch 106, and configuring the gas distribution branches 108 communicating with both the outer ring branch 106 and the external inlet branch 107, ensures that the external air duct 102 is reasonably and compactly distributed within the gas distribution plate 1. This results in balanced gas pressure when the gas flows into the outer ring branch 106, leading to excellent flame output.

[0031] In this embodiment of the invention, there are two gas distribution branches 108. These two branches extend circumferentially around the gas distribution plate 1 and are arranged opposite each other radially. One end of the outer inlet branch 107 is connected to the two gas distribution branches 108, and the other end forms an outer air inlet 104. This arrangement, by configuring two gas distribution branches 108 that extend circumferentially around the gas distribution plate 1 and are arranged opposite each other radially, ensures that the gas pressure is balanced when the combustion gas flows into the outer ring branch 106, resulting in excellent flame output.

[0032] In this embodiment of the invention, the inner air passage 101 further includes an inner inlet branch passage 109. One end of the inner inlet branch passage 109 is connected to the central branch passage 105, and the other end forms an inner air inlet 103. The inner inlet branch passage 109 extends radially along the gas distribution plate 1 and is located at the lower end of the central branch passage 105. The outer inlet branch passage 107 extends radially along the gas distribution plate 1 and is arranged side by side with the inner inlet branch passage 109. The inner air inlet 103 and the outer air inlet 104 are arranged side by side. By configuring the inner inlet branch passage 109, which extends radially along the gas distribution plate 1, on the inner air passage 101, with one end connected to the central branch passage 105 and the other end forming an inner air inlet 103, the inner air passage 101 is reasonably and compactly distributed within the gas distribution plate 1. When the gas flows into the central branch passage 105, the gas pressure is balanced, resulting in excellent flame output.

[0033] Meanwhile, by arranging the outer intake branch 107 and the inner intake branch 109 side by side, and the inner air intake 103 and the outer air intake 104 in a side by side, the inner air intake 101 and the outer air intake 102 are reasonably and compactly distributed in the air distribution plate 1.

[0034] In this embodiment of the invention, the air distribution plate 1 includes an upper plate 110 and a lower plate 111. The upper plate 110 and the lower plate 111 are stacked vertically to form an inner air passage 101 and an outer air passage 102. The upper plate 110 and the lower plate 111 are detachably and fixedly connected. By configuring the air distribution plate 1 with a detachably and fixedly connected upper plate 110 and lower plate 111, the air distribution plate 1 is easy to disassemble, install, and maintain.

[0035] In this embodiment of the invention, the upper plate 110 is provided with an upper support channel 112, and the lower plate 111 is provided with a lower support channel 113. The upper support channel 112 and the lower support channel 113 are arranged vertically to form a central support channel 105. The upper plate 110 has a positioning ring 114 extending from the lower end of the upper support channel 112 into the lower support channel 113. The inner wall of the lower support channel 113 is provided with a vertically extending retaining strip 115, and the positioning ring 114 is provided with a retaining groove 116 for inserting the retaining strip 115. The above arrangement, by configuring the positioning ring 114 extending from the lower end of the upper support channel 112 into the lower support channel 113 on the upper plate 110, configuring the vertically extending retaining strip 115 on the inner wall of the lower support channel 113, and configuring the retaining groove 116 on the positioning ring 114 for inserting the retaining strip 115, makes the upper plate 110 and the lower plate 111 stably assembled.

[0036] In this embodiment of the invention, the upper plate 110 is provided with an outer ring branch 106, and the lower plate 111 is provided with an outer inlet branch 107, an air distribution branch 108, and an inner inlet branch 109. This arrangement, by configuring the outer inlet branch 107, air distribution branch 108, and inner inlet branch 109 on the lower plate 111 and the outer ring branch 106 on the upper plate 110, ensures that the inner air passage 101 and the outer air passage 102 are reasonably and compactly distributed on the upper plate 110 and the lower plate 111.

[0037] In this embodiment of the invention, the two air distribution channels 108 are connected to the end of the outer air intake channel 107 away from the outer air intake port 104. The length direction of the outer air intake channel 107 is defined as the front-to-back direction. The lower plate 111 has a base shell 119 and a rear cover 120. The base shell 119 and the rear cover 120 are arranged front to back to form the outer air intake channel 107 and the air distribution channels 108. The rear cover 120 is riveted to the base shell 119. The above arrangement, by configuring the two air distribution channels 108 to be connected to the end of the outer air intake channel 107 away from the outer air intake port 104, and configuring the lower plate 111 to be arranged front to back to form the base shell 119 and the rear cover 120 of the outer air intake channel 107 and the air distribution channels 108, and riveting the rear cover 120 to the base shell 119, makes the lower plate 111 compact, easy to process and assemble.
