Description

Technical Field

[0001] This invention relates to the field of kitchen appliances technology, specifically to a heat storage infrared radiation burner. Background Technology

[0002] Currently, commercial gas stove burners utilize a mixing structure to organize the mixing of gas and air. The mixed gas flows out from the burner and is ignited by the open flame of the ignition source. After initial combustion in the burner's combustion chamber, the combustion flame flows outward from the combustion chamber. Most of the combustion reaction occurs as the flame impacts the bottom of the cookware and spreads outward after exiting the combustion chamber. The combustion reaction occurring solely within the combustion chamber accounts for only a small portion of the entire combustion process. This is because the combustion reaction between gas and oxygen in the air involves the absorption and release of heat. Most of the unburned gas is already being released from the combustion chamber while still absorbing the heat required for combustion, flowing to the bottom of the cookware and causing friction between the cookware and the air. The gas, which competes for the heat required for combustion and fails to complete the combustion reaction, enters a larger-volume furnace to continue the remaining combustion process. This inevitably leads to the dispersion of combustion heat, thereby reducing the temperature and intensity of the combustion reaction and lowering the energy conversion efficiency ratio. To create a relatively high-temperature combustion environment for the gas that has not yet completed the combustion reaction, some stoves place combustion aid plates in the furnace above the burner outlet. These combustion aid plates are mostly made of porous ceramic plates, iron-chromium-aluminum honeycomb plates, or wire mesh. While these combustion aid plates can significantly improve the heat conversion efficiency by assisting in improving the combustion reaction performance and heat exchange performance, lightweight materials such as porous ceramic plates and iron-chromium-aluminum honeycomb plates are easily eroded and damaged by high-temperature flames, thus increasing the production and maintenance costs of gas stoves. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a regenerative infrared radiation burner. The radiation chamber acts as a heat conversion carrier, and the flame emitted laterally from the burner directly heats the inner wall of the chamber, raising its surface to over 1100 degrees Celsius. This intensely heated inner wall then radiates heat outwards through high-intensity radiation. This radiated heat is efficiently absorbed and utilized by the cookware, significantly increasing the combustion environment temperature within the combustion chamber and promoting a faster and more complete combustion reaction, thus achieving continuous and efficient heat conversion. This solves the problem of incomplete combustion and low thermal energy utilization caused by dispersed heat during the combustion reaction.

[0004] The technical solution is as follows: a regenerative infrared radiation burner, comprising an ignition device and a radiation barrel formed by a side wall, the interior of which is a combustion chamber. The lower part of the radiation barrel is sealed and connected to a mixer. The mixer includes a hollow mixing chamber, an air inlet communicating with the mixing chamber, and a mixing pipe communicating with the mixing chamber. A sealing cover is provided on the upper part of the mixer, and a flame distributor is installed on the upper part of the sealing cover. The flame distributor is a cover with an opening facing downwards, and a mixed gas distribution chamber is formed inside the cover. The side wall of the flame distributor has multiple flame holes that communicate between the mixed gas distribution chamber and the combustion chamber. The mixing pipe passes through the sealing cover and extends upwards to the lower part of the flame distributor. The ignition device passes upwards through the sealing cover and communicates with the combustion chamber.

[0005] Furthermore, the mixing pipe is a U-shaped pipe, with the outlet of the U-shaped pipe higher than the inlet. The inlet is located inside the mixing chamber, and the outlet extends upward into the mixed gas distribution chamber.

[0006] Furthermore, the sealing cover includes a lower cover and an upper cover. The lower cover seals the upper part of the mixing chamber, and the upper cover fits onto the upper part of the lower cover. The upper edge of the lower cover has a notch, and the ignition device penetrates through the lower cover. The top of the ignition device is located in the notch, and the top of the ignition device covers the lower part of the upper cover.

[0007] Furthermore, the radiation barrel has a bottom surface with a through hole, which is sealed to the upper part of the mixing chamber.

[0008] Furthermore, the air intake includes a gas intake and an air intake, with the gas intake disposed on the side wall of the mixer and the air intake disposed at the bottom of the mixer.

[0009] Furthermore, the ignition device includes an ignition needle and a normally lit flame tube.

[0010] Furthermore, the mixer is inserted into the through hole, and a flange is provided around the outside of the mixer, with the bottom of the radiation barrel pressing against the upper part of the flange.

[0011] Furthermore, the length of the fire hole is not less than 6mm.

[0012] Furthermore, the inner diameter of the combustion chamber is 160mm-200mm, the thickness between the outer and inner walls of the radiant barrel is not less than 30mm, and the height of the combustion chamber is 150mm-200mm.

[0013] Furthermore, the upper part of the flame divider is provided with a flame divider protective cover, which includes a heat insulation pad and a heat insulation shell. The heat insulation pad wraps around the upper part of the flame divider, and the heat insulation shell wraps around the heat insulation pad. The bottom edge of the heat insulation shell is provided with a rolled edge extending towards its center, and the upper edge of the flame divider is provided with a groove around its perimeter. The rolled edge is engaged in the groove.

[0014] Furthermore, the radiation barrel is made of inorganic non-metallic material.

[0015] Compared with the prior art, the present invention has the following advantages: 1. A high-temperature combustion environment is conducive to the rapid and complete combustion reaction between fuel gas and air; 2. A relatively enclosed combustion chamber is conducive to better accumulation of the heat released by the combustion reaction and to becoming a heat transfer carrier for higher temperature rise; 3. The combustion gases flow out through the horizontally arranged flame holes and directly impact the inner wall of the combustion chamber, which is conducive to the violent disturbance of the combustion flame airflow and the rapid return of high-temperature heat, which is used for the combustion of subsequent outflowing gases. This is conducive to the combustion gases obtaining sufficient heat for the combustion reaction in the first time they flow out of the flame holes. The violent airflow disturbance, the return of high-temperature heat, and the curved flow trajectory of the combustion gases are conducive to the combustion reaction process of the gas and air in the combustion chamber for a longer time, faster, and more complete. The high-temperature flue gas heat output upward by changing the flow trajectory, together with the radiant heat emitted by the radiant barrel and the heat insulation shell, is absorbed and utilized by the cookware. The huge temperature difference between the radiant barrel and the flue gas and the cookware is conducive to high-intensity and high-efficiency heat conversion. 4. The radiant tub is made of inorganic non-metallic material with a thickness of more than 30 mm, which has better thermal insulation performance, helps to reduce heat conduction to the outside space, and helps to reduce heat loss.

[0021] Reference Figure 1-15 A regenerative infrared radiation burner includes an ignition device 5 and a radiation barrel 2 formed by a side wall. The interior of the radiation barrel 2 is a combustion chamber 21. The radiation barrel 2 has a bottom surface with a through hole that is sealed to the upper part of a mixer 1. The mixer 1 includes a hollow mixing chamber 14, an air inlet communicating with the mixing chamber 14, and a mixing pipe 4 communicating with the mixing chamber 14. The air inlet includes a gas inlet 13 and an air inlet 12. The gas inlet 13 is located on the side wall of the mixer 1. An air intake duct 12 is located at the bottom of the mixer 1. A sealing cover is provided on the upper part of the mixer 1. An igniter 3 is installed on the upper part of the sealing cover. The igniter 3 is a cover with its opening facing downwards. A mixed gas distribution chamber 32 is formed inside the cover. The side wall of the igniter 3 is provided with multiple flame holes 31 that connect the mixed gas distribution chamber 32 to the combustion chamber 21. The length of the flame hole 31 is not less than 6 mm. The mixing pipe 4 passes through the sealing cover and extends upwards into the mixed gas distribution chamber 32. The ignition device 5 passes through the sealing cover upwards and communicates with the combustion chamber 21.

[0022] The mixing pipe 4 is a U-shaped pipe, with the outlet 42 of the U-shaped pipe higher than the inlet 41. The inlet 41 is located inside the mixing chamber 14, and the outlet 42 extends upward into the flame distributor 3. By using a U-shaped pipe as the mixing pipe 4, the air intake duct 12 and the gas intake duct 13 are moved away from the inlet 41, extending the entry time of the mixed gas and allowing the mixed gas to be mixed more thoroughly in the mixing chamber 14.

[0023] The sealing cover includes a lower cover 62 and an upper cover 61. The lower cover 62 seals the upper part of the mixing chamber 14, and the upper cover 61 fits onto the upper part of the lower cover 62. The upper edge of the lower cover 62 has a notch 63. The ignition device 5 passes through the lower cover 62, and the top of the ignition device 5 is located in the notch 63. The top of the ignition device 5 covers the lower part of the upper cover 61. The ignition device 5 includes an ignition needle 51 and a constant flame tube 52. The vent holes on the ignition needle 51 and the constant flame tube 52 are located in the notch 63, allowing the constant flame to burn continuously. The ignition needle 51 can be an ignition needle 51 with a flameout protection device.

[0024] The mixer 1 can be inserted into the through hole of the radiation tank 2. The mixer 1 has a flange 11 around its periphery, and the bottom of the radiation tank 2 presses against the upper part of the flange 11.

[0025] A protective cover can be installed on the upper part of the burner 3. The protective cover includes a heat insulation pad 33 and a heat insulation shell 34. The heat insulation pad 33 covers the upper part of the burner 3, and the heat insulation shell 34 covers the heat insulation pad 34. The bottom edge of the heat insulation shell 34 has a rolled edge 36 extending towards its center, and the upper edge of the burner 3 has a groove 35. The rolled edge 36 is engaged in the groove 35. This protective cover protects the material of the burner 3 from high-temperature erosion, prevents excessive temperature rise of the burner 3 structure, and reduces the probability of backfire caused by high temperature. The protective cover absorbs heat to reach a high-temperature red-hot state, which can further improve the combustion environment and combustion reaction temperature, and improve the intensity and efficiency of radiative heat transfer.

[0026] The combustion chamber 21 has an inner diameter of 160mm-200mm, and the thickness between the outer and inner walls of the radiant barrel 2 is not less than 30mm. The combustion chamber 21 is 150mm-200mm high. The radiant barrel 2 is made of inorganic non-metallic material. This burner is placed inside the stove support 7 for use, and the cookware 8 is supported by the upper edge of the stove support 7.

[0027] In use, gas is introduced into the constant flame tube 52, and then the ignition needle 51 is discharged to ignite the gas flowing out of the constant flame tube 52. Subsequently, gas is introduced into the air intake duct 12 and the gas intake duct 13. The air and gas are fully mixed through the mixer 14 and enter the mixing pipe 4, and then enter the mixed gas distribution chamber 32 through the outlet 42. The flame distributor 3 is a round cap. The internal cavity of the flame distributor 3 is a mixed gas distribution chamber 32, and the outside is a combustion chamber 21. The side wall of the flame distributor 3 is provided with flame holes 31. The mixed gas flows out laterally through the flame holes 31 and directly impacts the inner wall of the radiant barrel 21. The flame gas flowing back and then collide with the flame gas flowing out laterally, causing violent disturbance and diffusion. The flame gas directly impacts the inner wall of the radiant barrel 21, causing it to rapidly absorb a large amount of heat. After the inner wall of the radiant barrel 21 is heated to a high temperature and red-hot, it further outputs the high-temperature heat through high-temperature thermal radiation, providing high-temperature heat for the combustion of the subsequent outflowing gas. This can further increase the temperature rise of the combustion chamber 21 and the combustion reaction temperature and reaction intensity. The combustion reaction fully releases heat, which is absorbed and utilized by the cookware 8 through radiation and convection.
