Description

Technical Field

[0001] The present invention relates to the technical field of gas devices, and in particular to a burner and a gas device. Background Art

[0002] During the cooking process, ingredients sometimes require a higher level of heat energy. Generally, this is achieved by increasing the gas flow rate, which increases the amount of gas ignited per unit time, thereby increasing the heat energy provided by the gas burner.

[0045] The present invention provides a burner 100 .

[0046] Reference Figures 1 to 10 The burner 100 proposed in the technical solution of the present invention includes:

[0047] The first combustion assembly 10 includes:

[0048] A rectifying and combustion-supporting component 13, wherein the rectifying and combustion-supporting component 13 is provided with an air inlet hole 131;

[0049] A first burner 15, which is disposed around the rectifying combustion-supporting member 13, and has a first gas channel 311 therein. The first gas channel 311 has a first air inlet 153 and a plurality of first air outlets 155; and

[0050] a first furnace drum 17, the first furnace drum 17 being disposed on the first burner 15, the first furnace drum 17 and the first burner 15 jointly enclosing a first combustion chamber 11, the air inlet 131 and the plurality of first air outlets 155 being in communication with the first combustion chamber 11; and

[0051] A second combustion assembly 30 includes a second burner 31. The second burner 31 is located above the first burner 15 and surrounds the first furnace drum 17. A second gas channel 151 is defined within the second burner 31. The second gas channel 151 includes a second air inlet 313 and a plurality of second air outlets 315. The plurality of second air outlets 315 surround the first furnace drum 17.

[0052] The second furnace drum 33 is placed on the side of the second burner 31 away from the first burner 15, and is arranged around the first furnace drum 17. The second furnace drum 33 and the second burner 31 together form a second combustion chamber 35. Multiple second air outlets 315 are connected to the second combustion chamber 35, and the second combustion chamber 35 is connected to the first combustion chamber 11.

[0053] The technical solution of the present invention is to set a first burner 15 in the first combustion assembly 10, set a first gas channel 311 with a first air inlet 153 and a plurality of first air outlets 155 in the first burner 15, and set a first furnace drum 17 arranged on the first burner 15, so that the first furnace drum 17 and the first burner 15 are enclosed together to form a first combustion chamber 11, and the air supply hole of the rectifying combustion-supporting component 13 is connected to the first combustion chamber 11, and further set a second burner 31 in the second combustion assembly 30, set a second gas channel 151 with a second air inlet 313 and a plurality of second air outlets 315 in the second burner 31, and set a second furnace drum 33 arranged on the second burner 31, so that the second furnace drum 33 Together with the second burner 31, a second combustion chamber 35 is formed, and the second combustion chamber 35 is connected to the first combustion chamber 11, wherein the second combustion assembly 20 is stacked on the first combustion assembly 10. When the burner is needed for combustion, air is input into the rectifying combustion-supporting component 13, so that the air flows into the first combustion chamber 11 from the air supply hole, and gas is input into the first combustion channel from the first air inlet 153, so that the air flows into the first combustion chamber 11 from the first air outlet 155, and then the air and gas are mixed in the first combustion chamber 11, and the first combustion chamber 11 is ignited, so that a low-power combustion mode can be achieved. In addition, since the rectifying combustion-supporting component 13 is arranged in the first combustion chamber 11, the gas ejected from the first air outlet 155 is sprayed toward the rectifying combustion-supporting component 13. Component 13, the rectifying combustion-supporting component 13 rectifies the flame formed after the combustion of the gas, ensures that the combustion shape of the flame is better, and makes the flame burn evenly, thereby improving the combustion efficiency; further, since the rectifying combustion-supporting component 13 is heated, the material of the rectifying combustion-supporting component 13 can be a metal material, and its specific heat capacity is much greater than the specific heat capacity of the gas and air. Therefore, the heated rectifying combustion-supporting component 13 can heat the mixed gas in the first combustion chamber 11 (catalytic combustion), further improving the combustion efficiency in the first combustion chamber 11; when it is necessary to use the high-power combustion mode, gas is sent from the second air inlet 313 to the second gas channel 151, so that the gas enters the second combustion chamber 35 from the second air outlet 315. The second combustion chamber 35 is connected to the first combustion chamber 11, and the second combustion assembly 20 is arranged on the first combustion assembly 10. As the hot air rises, the gas in the second combustion chamber 35 is ignited by the flame of the first combustion chamber 11, thereby raising the flame of the burner to a high-power mode. When it is necessary to switch back to a low-power mode, it is only necessary to stop supplying gas to the second combustion chamber 35, so that the gas only burns in the first combustion chamber 11, thereby achieving flexible switching between high and low power. Moreover, since the first combustion chamber 11 is connected to the second combustion chamber 35, the second combustion chamber 35 is ignited by the first combustion chamber 11. Since the increased gas is not burned in the original combustion chamber, the combustion efficiency of the gas is greatly increased, thereby greatly improving the heating efficiency of the burner.

[0054] In one embodiment, the size of the second combustion assembly 20 is larger than that of the first combustion assembly 10. Specifically, the width and height of the second burner 31 and the second furnace barrel 33 of the second combustion assembly 20 are both larger than the height of the first burner 15 and the first furnace barrel 17 of the first combustion assembly 10. This arrangement makes the volume of the second combustion chamber 35 much larger than the volume of the first combustion chamber 11, thereby greatly improving the combustion efficiency of the burner 100. By setting the small first combustion chamber 11 below the large second combustion chamber 35, the setting space of the burner 100 can be reasonably utilized, and greater power can be achieved in a smaller area.

[0055] In one embodiment, the width of the rectifying combustion-supporting component 13 is gradually reduced from bottom to top. Such a configuration can guide the flame to the middle position, making the flame temperature higher, and buffering and guiding the gas ejected from the first gas outlet 155, thereby improving the combustion efficiency of the gas in the first combustion chamber 11.

[0056] In this embodiment, the number of the first air inlet 153 can be multiple, thereby facilitating an increase in the gas intake flow rate and improving the heating efficiency. Furthermore, since both ends of the first furnace drum 17 are open, one end can be used for air intake, while the other end can be used to provide heat energy generated by gas combustion, thereby improving the use effect.

[0057] In some embodiments of the present invention, the rectifying combustion-supporting member 13 is roughly in the form of a right prism with a circular or polygonal bottom surface. The middle portion of the rectifying combustion-supporting member 13 is formed with an air inlet 131 that runs through the length of the rectifying combustion-supporting member 13, thereby facilitating air transmission. The rectifying combustion-supporting member 13 can be made of metal to improve its structural stability. In one embodiment, the aperture of the air inlet 131 can be gradually reduced from the air inlet side to the air outlet side. Such a configuration can increase the flow rate of air during exhaust, ensure the contact efficiency between air and gas, and improve the combustion efficiency of gas.

[0058] In one embodiment, to facilitate the placement of the first furnace drum 17 on the first burner 15, a limiting portion 318 may be provided on one of the first furnace drum 17 and the first burner 15, thereby facilitating the positioning of the other component. The limiting portion 318 may be a limiting rib or a limiting groove. If it is a limiting rib, it may be provided on the surface of the first burner 15, thereby limiting and fixing the first furnace drum 17. Alternatively, the first furnace drum 17 and the first burner 15 may be detachably connected via a connector. For example, both the first furnace drum 17 and the first burner 15 may be provided with connecting holes, and the connecting member may pass through the two connecting holes to achieve a detachable fixed connection between the two. This improves the structural stability of the first combustion assembly 10, thereby improving combustion efficiency.

[0059] Reference Figure 6 、 Figure 7 In some embodiments of the present invention, the first burner 15 is annular in shape, and the first air outlet 155 is located inside the first burner 15. The first burner 15 also includes an inwardly extending first support 157. The rectifying and combustible component 13 is mounted on the first support 157 and positioned within the first combustion chamber 11. The annular shape of the first burner 15 allows air to be supplied from the center of the first burner 15, improving the combustion efficiency of the gas. Furthermore, since both the first air outlet 155 and the rectifying and combustible component 13 are located inside the first burner 15, the gas and air can mix immediately upon entering the first combustion chamber 11, improving the combustion efficiency of the gas. Furthermore, the provision of the first support 157 to support the rectifying and combustible component 13 improves its installation efficiency, allowing air to flow out of the rectifying and combustible component 13 stably, thereby ensuring the combustion efficiency of the gas. The first air outlet can be positioned toward the outlet side of the air supply hole to facilitate improved mixing efficiency of the air and gas.

[0060] Specifically, the first burner 15 is arranged in a circular ring shape. This can save the installation space of the first burner 15 under the same circumference and ensure that the first air outlet 155 has more installation positions. In addition, after the cross-sections of the first burner 15 and the first furnace barrel 17 are both arranged in a circular shape, the friction noise during rotation and mixing can be reduced, making it more convenient for users. In one embodiment, the first air outlet 155 can also be arranged as a swirl air outlet. In one embodiment, the extension line of the air outlet direction of the swirl air outlet is the secant line of the first burner 15. Specifically, the inner side of the first burner 15 is raised to form an air outlet bump. The air outlet bump has an inner surface facing the rectifying combustion-supporting component 13 and a side surface connecting the inner surface to the first burner. The swirl air outlet is arranged on the side of the air outlet bump and is connected to the first gas channel 311. The air and gas in the first combustion chamber 11 are caused to rotate and mix, improving the mixing efficiency and thereby improving the combustion efficiency of the gas.

[0061] In this embodiment, the provision of multiple second air outlets 315 can greatly increase the gas outlet volume. The number of the second air inlet 313 can be multiple, thereby facilitating the increase of the gas intake flow rate and the heating efficiency.

[0062] Reference Figure 3 、 Figure 6 、 Figure 7In some embodiments of the present invention, the upper surface of the first burner 15 is raised to form a plurality of protrusions 159. Each first air outlet 155 is located on the inner side of a protrusion 159. The air intake side of the first furnace drum 17 is located on the upper surface of the protrusion 159. A first oxygen supply gap 1591 is formed between the two protrusions 159 for supplying air to the first combustion chamber 11. It can be understood that the provision of the protrusions 159 to form the first oxygen supply gap 1591 allows air to enter the first combustion chamber 11 through the first oxygen supply gap 1591 during combustion in the first combustion chamber 11 (due to the low pressure of the combustion gas), thereby improving the combustion efficiency of the gas in the first combustion chamber 11. In one embodiment, the air supply effect to the first combustion chamber 11 can also be improved by providing through holes in the inner wall of the first combustion chamber 11.

[0063] In some embodiments of the present invention, there are multiple first carriers 157, each of which is spaced apart from the other. The rectifying and combustion-supporting member 13 is placed on the surface of the multiple first carriers 157, and a second oxygen supply gap 1571 is formed between two first carriers 157 for supplying air to the first combustion chamber 11. By providing multiple first carriers 157, the rectifying and combustion-supporting member 13 can be well supported, improving the installation efficiency of the rectifying and combustion-supporting member 13 and ensuring that the rectifying and combustion-supporting member 13 can stably supply air, thereby ensuring the combustion efficiency of the gas. Furthermore, a second oxygen supply gap 1571 is formed between two first carriers 157, so that when the first combustion chamber 11 is burning (due to the lower gas pressure at the combustion location), air can enter the first combustion chamber 11 through the second oxygen supply gap 1571, thereby improving the combustion efficiency of the gas in the first combustion chamber 11.

[0064] Reference Figure 3 In some embodiments of the present invention, the second burner 31 is arranged in an annular shape, and is arranged around the outer side of the first furnace tube 17, and forms a third oxygen supply gap 317 between the second burner 31 and the first combustion assembly 10 for supplying air to the second combustion chamber 35; such an arrangement allows air to enter the second combustion chamber 35 from the third oxygen supply gap 317 when the second combustion chamber 35 is burning (due to the lower air pressure at the combustion location), thereby improving the combustion efficiency of the gas in the second combustion chamber 35.

[0065] In some embodiments of the present invention, the first burner 15 is provided with a first connecting portion 152, and the second burner 31 is provided with a second connecting portion 319. The first connecting portion 152 and the second connecting portion 319 are detachably connected. This arrangement ensures a secure connection between the first burner 15 and the second burner 31, facilitates assembly or disassembly as needed, and improves the performance of the burner 100. Specifically, the first connecting portion 152 can be provided with a first threaded hole, and the second connecting portion 319 can be provided with a second threaded hole. Bolts can be passed through the first and second threaded holes to achieve a detachable connection between the first burner 15 and the second burner 31. Alternatively, the first connecting portion 152 can be a buckle, and the second connecting portion 319 can be a slot. The detachable connection between the buckle and the slot achieves a detachable connection between the first burner 15 and the second burner 31.

[0066] Reference Figure 2 、 Figure 4 、 Figure 5 、 Figure 8 In some embodiments of the present invention, the second burner 31 is further provided with a limiting portion 318, and the limiting portion 318 is used to limit the relative position of the second furnace barrel 33 and the second burner 31; such a setting can ensure that the second furnace barrel 33 is firmly placed on the second burner 31, thereby ensuring the working stability of the second combustion assembly 30.

[0067] In some embodiments of the present invention, the second combustion assembly 30 is located above the first combustion assembly 10. Generally, air expands and rises when heated. Placing the second combustion assembly 30 above the first combustion assembly 10 facilitates the entry of hot air from the first combustion chamber 11 into the second combustion chamber 35, thereby igniting the gas in the second combustion chamber 35 and improving the combustion efficiency of the gas.

[0068] Reference Figures 4 to 6 ,as well as Figure 9 In some embodiments of the present invention, the burner 100 further includes a fire cover 50, which is cylindrical and covers the side of the first furnace tube 17 facing away from the first burner 15. The fire cover 50 is accommodated in the second combustion chamber 35. The outer surface of the fire cover 50 is provided with a fire guide groove 51, and the second air outlet 315 is arranged toward the fire guide groove 51. The fire cover 50, also known as a flame divider, is the part with the highest temperature at the upper end of the burner 100, and is mainly made of copper or cast iron. By providing the fire cover 50, the flame formed in the second combustion chamber 35 is guided, so that a stable flame shape is formed in the second combustion chamber 35. In addition, by facing the second air outlet 315 toward the fire guide groove 51, the gas can be directly sprayed toward the fire guide groove 51 after being ignited, and can then be directly guided by the fire guide groove 51 to form a stable flame shape.

[0069] Reference Figures 4 to 6 ,as well as Figure 9 In some embodiments of the present invention, the width of the fire cover 50 gradually decreases from bottom to top. The side of the first furnace barrel 17 facing away from the first burner 15 abuts the inner sidewall of the fire cover 50. The second burner 31 is also provided with a second support member 316, and the air intake side of the fire cover 50 is placed on this second support member 316. This arrangement not only facilitates the fire cover 50 to guide the flame, but also allows the fire cover 50 to be sleeved onto the first furnace barrel 17, thereby guiding the hot air rising from the first furnace barrel 17, improving the combustion efficiency of the gas and facilitating the placement of the fire cover 50. Furthermore, the second support member 316 supports the fire cover 50, further ensuring its stability. Furthermore, because the fire cover 50 is heated, it can be made of a metal material, whose specific heat capacity is much greater than that of the gas and air. Therefore, the heated fire cover 50 heats the mixed gas in the second combustion chamber 35 (catalytic combustion), further improving the combustion efficiency within the second combustion chamber 35.

[0070] In some embodiments of the present invention, the burner 100 further includes a third combustion assembly having a third combustion chamber and a plurality of third gas outlets connected thereto. The third combustion chamber is connected to the second combustion chamber 35. By providing the third combustion assembly, when the heating efficiency of the burner 100 needs to be improved, gas can be supplied to the third combustion assembly, causing the gas to flow from the third gas outlets into the third combustion chamber. Since the second combustion chamber 35 is connected to the third combustion chamber, the third combustion chamber is ignited by the second combustion chamber 35. Since the additional gas is not burned in the original combustion chamber, the combustion efficiency of the gas is greatly increased, thereby greatly improving the heating efficiency of the burner 100. The third combustion assembly can be disposed above the second combustion assembly 30, so that the hot air in the second combustion chamber 35 rises and directly ignites the gas in the third combustion chamber, thereby improving the combustion efficiency of the gas.
