[0002] At present, most of the burners used in commercial gas stoves use an independent burner head to do work. The burning flame flows out from the ignition distributor of an independent burner. The cross-sectional area of ​​the ignition outlet of the ignition distributor is very different from the area of ​​the heat absorption and utilization of the bottom of the wok or soup bucket that uses heat. The flame and heat flowing out of the ignition distributor and the work path flow from the center of the bottom of the pot to the periphery. The temperature and volume heat density of the burning flame gradually decrease and diffuse as the gas flows over a long distance, which will result in uneven characteristics such as a higher temperature rise and greater heat exchange intensity in the center area of ​​the bottom of the pot, and a lower temperature rise and lower heat exchange intensity in the periphery of the bottom of the pot. This will cause the disadvantage of uneven heating of the cooking food, and the disadvantage of reduced thermal energy utilization due to the low heat exchange intensity of the periphery of the pot. Therefore, a burner that can work synchronously over a larger area at the bottom of the pot, has an ultra-small space combustion chamber and ultra-close heat conversion, and is used in combination with multiple ignition distributors and combustion bowls on a tray is designed.

The present invention sets the burner as a plurality of independent combustion units, which can be used together with the pot in a larger The heat energy conversion is carried out synchronously over a short distance under the condition of a small area. Through the high-temperature heat storage of the combustion bowl entity, the premixed gas flowing out from the ignition head can be effectively promoted to realize a high-intensity combustion reaction in a very small space in the combustion bowl. The high-temperature and high-volume-density combustion flame and heat can be attached to the surface of the cookware over a short distance for high-efficiency heat conversion. Therefore, the combustion performance of the burner and the heat exchange performance of the cookware can be well optimized. In addition, the radiation plate further helps to increase the temperature of the combustion environment, and the radiation plate wall and the tray wall help to fully absorb and utilize the waste heat of the flue gas. Therefore, the present invention has a novel structure, an atmospheric feel, and excellent combustion and heat exchange performance, and can provide beneficial support for improving the energy efficiency ratio and temperature rise rate of gas appliances.

[0017] The ignition head 1 is a cylindrical tubular structure, including a tube wall 1-1, a closed end 1-2 at the top and a mixed gas inlet 1-4 at the bottom. A fire hole 1-3 is arranged at a lower position of the tube wall 1-1. Inside the entrance of the fire hole 1-3 is a distribution chamber 1-5, and outside the exit of the fire hole 1-3 is a combustion reaction zone 2-3; the ignition head 1 is placed in the middle of the combustion bowl 2, and the combustion bowl 2 is a plate-shaped profiling structure. The bottom of the combustion bowl 2 is flat and the outer periphery is upwardly tilted 2-1. One ignition head 1 and one combustion bowl 2 constitute a combustion work unit. Multiple The combustion work units are distributed at a certain interval and placed on the radiation plate 4. The outer periphery of the radiation plate 4 has an upwardly turned wall 4-1; the lower part of the radiation plate 4 is the tray 5, and the lower part of the tray 5 is the mixer 8. The radiation plate 4 and the tray 5 are provided with gas pipe mounting holes 4-2 and 5-2 corresponding to the positions of the combustion bowl 2, and the upper end surface of the mixer 8 is provided with a mixed gas outlet; the gas pipe 7 passes through the mounting holes 4-2 and 5-2 of the radiation plate 4 and the tray 5, assembles the ignition head 1, the combustion bowl 2, the radiation plate 4, the tray 5 and the mixer 8, and connects the gas passage.

[0018] The outer ring of the combustion bowl 2 is tilted upward 2-1, and the preferred tilting angle 2-2 is greater than 55 degrees and less than 80 degrees. It can effectively guide the combustion flame of the premixed gas flowing out from the spark hole 1-3 of the ignition head to flow out obliquely upward, so that the combustion flame can be closely attached to the bottom of the cookware to do work under the condition of smaller gas flow resistance.

[0019] The end 1-2 of the ignition head 1 is used to support the cookware, and its horizontal height is higher than the horizontal height of the upper end surface of the bowl edge of the outer protrusion 2-1 of the combustion bowl. The preferred height difference 3 is 5-8 mm, which can maintain the optimal distance between the combustion bowl and the bottom of the cookware, so that the flame heat volume density in the combustion reaction zone inside the combustion bowl is the highest, and the high-temperature radiant heat of the combustion bowl is more efficiently transferred to the cookware.

[0020] There is an upwardly raised wall 4-1 at the outer ring position of the radiation plate 4. The top of the wall 4-1 is convex and concave like the walls of the Great Wall. The upper end surface of the raised part is used to support the pot, and the concave part is used for smoke discharge, which can balance the exhaust gas outflow pressure and make the exhaust gas heat adhere to the bottom of the pot and flow, thereby increasing the heat absorption efficiency.

[0021] The tray 5 is located in the outer area of ​​the radiation plate 4 and is provided with an annular pot support. The top shape of the pot support 5-1 is concave like the wall of the Great Wall. The upper end surface of the convex part is used to support the pot, and the concave part is used for the smoke exhaust channel, which can balance the exhaust gas outflow pressure and allow the exhaust gas heat to flow along the bottom of the pot, thereby increasing the heat absorption efficiency.

[0022] The upper end surface of the ignition head 1 is preferably in the same horizontal plane as the upper end surface of the protrusion of the radiation plate wall 4-1 and the upper end surface of the protrusion of the tray pot support 5-1. It can be in full contact with the flat-bottomed pot at a close distance, so that the smoke heat can flow more closely to the bottom of the pot, which is conducive to completing efficient heat conversion within a shorter distance.

[0023] An annular groove 6 is provided between the radiation plate enclosure 4-1 and the tray pot support 5-1, which can balance the exhaust gas emission, slow down the heat loss rate, and reduce the transmission of combustion reaction noise to the outside.
