Description

Technical Field

[0001] This utility model relates to a stove, and more particularly to a burner head and a gas stove. Background Technology

[0002] There are various combustion methods for burners, such as single-ring combustion or double-ring combustion. In a double-ring combustion burner, two injectors are required to supply gas to the outer and inner flames. When the two injectors are close together, interference occurs when outside air is supplied to them. Currently, the horizontal distance between the two injectors is increased to increase the amount of air supplied. However, the maximum possible offset between them is limited, and insufficient air supply is not achieved when a large amount of air is required. Therefore, a burner that can adequately supply air is urgently needed. Utility Model Content

[0003] The purpose of this utility model is to provide a burner head and a gas stove to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A burner head includes: a flame distributor with a flame outlet groove on its top side; an inner mixing chamber and an outer mixing chamber disposed within the flame distributor, the outer mixing chamber surrounding the inner mixing chamber; a plurality of outgoing flame holes communicating with the outer mixing chamber on the side wall of the flame outlet groove; and a plurality of inner flame outlet holes communicating with the inner mixing chamber on the bottom of the flame outlet groove; a first ejector tube connected to the side wall of the flame distributor, the first ejector tube communicating with the outer mixing chamber, and the first ejector tube extending horizontally in a direction away from the flame distributor; and a second ejector tube connected to the bottom side of the flame distributor, the second ejector tube communicating with the inner mixing chamber, and the second ejector tube extending downward.

[0006] This technical solution has at least the following beneficial effects: The first ejector tube and the second ejector tube are respectively used to connect the external gas and air supply pipes. In use, gas and air are supplied from the first ejector tube to the outer mixing chamber, allowing the gas and air to mix further in the outer mixing chamber. Then, the gas is discharged from multiple outlet flame holes connected to the outer mixing chamber and burned to form an outer ring flame. Similarly, gas and air are supplied from the second ejector tube to the inner mixing chamber, allowing the gas and air to mix further in the inner mixing chamber. Then, the gas is discharged from multiple outlet flame holes connected to the inner mixing chamber and burned to form an inner ring flame. During this process, since the first ejector tube is set horizontally and the second ejector tube is set vertically, the first ejector tube and the second ejector tube are staggered in the horizontal and vertical directions and form a large distance, which effectively reduces the phenomenon of mutual interference when the outside air is supplied to the first ejector tube and the second ejector tube, thereby ensuring sufficient air supply capacity when forming a double ring flame, making the combustion more complete.

[0007] As a further improvement to the above technical solution, the line connecting any of the fire outlet holes to the center of the fire outlet groove on the inner side of the fire outlet groove is a reference line, and the gas outlet direction of the fire outlet hole deviates from the reference line.

[0008] As a further improvement to the above technical solution, a mixing mesh plate is provided inside the outer mixing chamber. The mixing mesh plate extends around the flame outlet groove and covers multiple flame outlet holes. Multiple connecting holes are provided on the mixing mesh plate.

[0009] As a further improvement to the above technical solution, an annular step is provided on the inner side of the outer mixing chamber surrounding the flame outlet groove, and the mixing mesh plate abuts against the annular step.

[0010] As a further improvement to the above technical solution, an arc-shaped protrusion is formed at the bottom of the flame outlet groove corresponding to the position of the second ejector tube, and a plurality of inner flame outlet holes are arranged around the periphery of the arc-shaped protrusion.

[0011] As a further improvement to the above technical solution, the gas outlet direction of the inner flame outlet is offset along the radial and axial directions of the arc-shaped protrusion.

[0012] As a further improvement to the above technical solution, the igniter is located between the inner mixing chamber and the outer mixing chamber and has an air intake channel. The air intake channel extends in the vertical direction and multiple air intake channels are arranged around the inner mixing chamber.

[0013] As a further improvement to the above technical solution, at least one notch is provided on the outer bottom of the second ejector tube, and the notch extends downward to the end of the second ejector tube.

[0014] As a further improvement to the above technical solution, the bottom side of the fire distributor is provided with multiple support feet surrounding the second ejector tube.

[0015] A gas stove includes a furnace body and a burner as described above, wherein the burner is disposed in the furnace body.

[0016] This technical solution has at least the following beneficial effects: In this furnace body, since the first ejector tube inside the burner head is set horizontally, while the second ejector tube is set vertically, the first ejector tube and the second ejector tube are staggered in the horizontal and vertical directions and form a large distance, which effectively reduces the phenomenon of mutual interference when the outside air is introduced into the first ejector tube and the second ejector tube, thereby ensuring sufficient air supply capacity when forming a double-ring flame, making the combustion more complete.

[0028] Reference Figures 1 to 4 A burner head includes a flame distributor 100, a first ejector, and a second ejector tube 300. The flame distributor 100 has a flame outlet groove 110 on its top side. The flame distributor 100 contains an inner mixing chamber 181 and an outer mixing chamber 182, which are independent of each other. The outer mixing chamber 182 surrounds the inner mixing chamber 181. The sidewall of the flame outlet groove 110 has multiple flame outlet holes 120 communicating with the outer mixing chamber 182. The bottom of the 0 slot is provided with multiple internal flare holes 130 that communicate with the internal mixing chamber 181; the first ejector tube 200 is connected to the side wall of the flare distributor 100, the first ejector tube 200 communicates with the external mixing chamber 182, and the first ejector tube 200 extends horizontally in a direction away from the flare distributor 100; the second ejector tube 300 is connected to the bottom side of the flare distributor 100, the second ejector tube 300 communicates with the internal mixing chamber 181, and the second ejector tube 300 extends downward.

[0029] As described above, the first ejector tube 200 and the second ejector tube 300 are respectively used to connect to the external gas and air supply pipes. In use, gas and air are supplied from the first ejector tube 200 to the outer mixing chamber 182, allowing the gas and air to mix further within the outer mixing chamber 182. Then, gas is released from multiple outlet flame holes 120 connected to the outer mixing chamber 182 and combusted, forming an outer ring flame. Similarly, gas and air are supplied from the second ejector tube 300 to the inner mixing chamber 181, allowing the gas and air to mix further within the inner mixing chamber 181. Then, gas is released from multiple outlet flame holes 120 connected to the outer mixing chamber 182 and combusted, forming an outer ring flame. Gas is released and burned through multiple inner flame outlets 130 in the inner mixing chamber 181 to form an inner ring flame. During this process, since the first ejector tube 200 is set horizontally and the second ejector tube 300 is set vertically, the first ejector tube 200 and the second ejector tube 300 are staggered in the horizontal and vertical directions and form a large distance, which effectively reduces the phenomenon of mutual interference when the outside air is introduced into the first ejector tube 200 and the second ejector tube 300. This ensures that there is sufficient air supply when the double ring flame is formed, so that the combustion is more complete.

[0030] As a specific structural embodiment of the flame distributor 100, the flame distributor 100 includes a bottom shell 171, a partition core 172 located inside the bottom shell 171, and a top cover 173 connected to the top side of the bottom shell 171. A flame outlet groove 110 is formed on the top side of the partition core 172. An opening is provided on the top cover 173 directly opposite the flame outlet groove 110. Multiple air outlet grooves are provided around the flame outlet groove 110 on the top side of the partition core 172. An external flame outlet 120 is formed between the top cover 173 and the multiple air outlet grooves. The inner... The part is provided with a cavity. The separator core 172 forms an inner mixing chamber 181 between the cavity and the top side of the bottom shell 171. The outer side of the separator core 172 forms an outer mixing chamber 182 between the outer side of the separator core 172 and the inner side of the bottom shell 171. The first ejector tube 200 is connected to the outer side of the bottom shell 171, thereby communicating with the outer mixing chamber 182. The second ejector tube 300 is connected to the bottom side of the bottom shell 171, thereby communicating with the inner mixing chamber 181. The top side of the separator core 172 is provided with a plurality of inner flame outlet holes 130 that communicate with its interior.

[0031] In the above embodiment, the gas outlet direction from the outlet flame port 120 to the flame outlet groove 110 can be towards the center of the flame outlet groove 110. However, in order to further improve the thermal efficiency of air and gas mixing and combustion, in this embodiment, the line connecting any one of the outlet flame ports 120 to the center of the flame outlet groove 110 on the inner side of the flame outlet groove 110 is used as a reference line, and the gas outlet direction of the outlet flame port 120 deviates from the reference line. When the gas outlet direction from the outlet flame port 120 to the flame outlet groove deviates from the center of the flame outlet groove 110, the gas outlet from the multiple outlet flame ports 120 to the flame outlet groove 110 rotates around the flame outlet groove 110, forming a rotating flame in the flame outlet groove. This can slow down the direct discharge of air and gas from the outer mixing chamber 182 to the outlet flame port 120, thereby improving the thermal efficiency of air and gas mixing, combustion, and discharge from the outlet flame port 120.

[0032] To further improve the mixing efficiency of air and fuel gas as they enter the outer mixing chamber 182 and exit flame holes 120, in this embodiment, a mixing mesh plate 400 is provided inside the outer mixing chamber 182. Naturally, the mixing mesh plate 400 has multiple mesh holes for ventilation. The mixing mesh plate 400 extends around the flame outlet groove 110 and covers multiple exit flame holes 120. The mixing mesh plate 400 has multiple connecting holes. In practical applications, the mixing mesh plate 400 is fitted onto the outside of the separator core 172 and directly opposite the positions of the multiple exit flame holes 120. Then, the top cover 173 is connected to the bottom shell 171. After the gas and air are mixed in the outer mixing chamber 182, they first pass through the mixing mesh. The mixing mesh plate 400 partially blocks the flow of gas and air from the outlet 120, which slows down the direct discharge of gas and air from the outlet 120. Under the pressure of the outer mixing chamber 182, the gas and air pass through the mesh on the mixing mesh plate 400 and are released and discharged in the outlet 120, thereby further improving the mixing efficiency of gas and air.

[0033] To improve the stability of the gas mixing mesh plate 400 during installation and positioning within the outer gas mixing chamber 182, in this embodiment, an annular step 140 is provided around the flame outlet groove 110 on the inner side of the outer gas mixing chamber 182. The gas mixing mesh plate 400 abuts against the annular step 140. In practical applications, an annular step 140 is formed on the outer side of the separator core 172, and then the gas mixing mesh plate 400 is fitted and positioned on the annular step 140. Thus, during installation of the gas mixing mesh plate 400, the annular step 140 provides support and positioning for the gas mixing mesh plate 400, effectively preventing the gas mixing mesh plate 400 from detaching from the separator core 172, making the installation of the gas mixing mesh plate 400 more convenient and stable.

[0034] Multiple inner flame outlets 130 can be directly disposed at the center of the bottom of the flame outlet groove 110. In this case, the flame outlet in the center of the flame outlet groove 110 is relatively concentrated. Therefore, to increase the flame outlet range in the inner ring, in this embodiment, an arc-shaped protrusion 111 is formed at the bottom of the flame outlet groove 110 corresponding to the position of the second ejector tube 300. Multiple inner flame outlets 130 are arranged around the periphery of the arc-shaped protrusion 111. The arc-shaped protrusion 111 itself can enhance the structural strength of the bottom of the flame outlet groove 110, making the inner flame outlets 130 less prone to deformation under high temperatures. Distributing multiple inner flame outlets 130 near the outer edge of the arc-shaped protrusion 111, i.e., at the periphery, can increase the number of flame outlets disposed in the horizontal and vertical directions and expand the gas outlet range, thereby improving the gas outlet combustion effect in the inner ring.

[0035] In the above embodiment, the inner flame outlet 130 can be directly arranged in the vertical direction, and the gas venting outward from the inner flame outlet 130 is directly upward. However, in this embodiment, the gas venting direction of the inner flame outlet 130 is offset radially and axially along the arc-shaped protrusion 111. The inner flame outlet 130 has an offset radially and axially along the arc-shaped protrusion 111. At this time, the gas venting outward from the multiple inner flame outlets forms a rotating airflow, which forms a rotating flame in the ignition state. The inclined arrangement of the inner flame outlets can prevent the gas and air from being directly discharged outward, improve the gas-air mixing efficiency, and further improve the thermal efficiency of combustion in the inner ring.

[0036] When the mixture of gas and air is discharged from the ignition slot 110 and burned, air needs to be added to the ignition slot 110 to improve combustion efficiency. Therefore, in this embodiment, the igniter 100 is located between the inner mixing chamber 181 and the outer mixing chamber 182 and has an air intake channel 150. The air intake channel 150 extends vertically and multiple air intake channels 150 are arranged around the inner mixing chamber 181. In use, outside air can be added from below the igniter 100 to the multiple air intake channels 150 and from the multiple air intake channels 150 to the ignition slot 110, thereby further supplementing the air required for combustion and improving the gas combustion efficiency.

[0037] The downward-extending second ejector tube 300 needs to be fixed to the external structure during installation. To facilitate the replenishment of gas and air, in this embodiment, at least one notch 310 is provided on the outer bottom of the second ejector tube 300. For example, notches 310 can be provided on both sides of the bottom of the second ejector tube 300, and the notches 310 extend downward to the end of the second ejector tube 300. During installation, the second ejector tube 300 is connected to the gas supply structure of the external device. At this time, the bottom end of the second ejector tube 300 is directly connected to the gas supply pipe, while the air supply pipe is connected to the notch 310, so that the gas and air enter the second ejector tube 300, mix, and then exit as gas.

[0038] To improve the stability of the fire distributor 100 during installation, in this embodiment, a plurality of support feet 160 are provided around the bottom side of the fire distributor 100 surrounding the second ejector tube 300. During installation, the plurality of support feet 160 are used to align and connect with the structure of the external device, thereby improving the stability of the fire distributor 100 during installation.

[0039] A gas stove includes a stove body and a burner as described above, wherein the burner 100 is disposed in the stove body.

[0040] This technical solution has at least the following beneficial effects: In this furnace body, since the first ejector tube 200 inside the burner head is set horizontally, while the second ejector tube 300 is set vertically, the first ejector tube 200 and the second ejector tube 300 are staggered in the horizontal and vertical directions and form a large distance, which effectively reduces the phenomenon of mutual interference when the outside air is introduced into the first ejector tube 200 and the second ejector tube 300, thereby ensuring sufficient air supply capacity when forming a double-ring flame, making the combustion more complete.
