[0039] The following embodiments are used to illustrate the present invention, but the present invention is not limited by these embodiments. Modifying the specific embodiments of the present invention or equivalently replacing some technical features without departing from the spirit of the present invention shall be covered within the scope of the technical solutions claimed by the present invention.
[0040] Embodiment 1
[0041] Please refer to Figures 1-7 , the present invention provides a burner, including an inner fire cover 2 and an outer fire cover 1. The inner fire cover 2 includes an inner fire cover body 21 and inner fire holes 22 arranged on the circumferential side of the inner fire cover body 21. An inner ring air groove 25 communicating with the inner fire holes 22 is arranged on the lower side of the inner fire cover body 21. The outer fire cover 1 includes an outer fire cover body 11 and outer fire holes 12 arranged on the circumferential side of the outer fire cover body 11. The inner fire cover body 21 is arranged inside the outer fire cover body 11. A secondary air passage 100 is arranged between the inner fire cover body 21 and the outer fire cover body 11. Gap fire holes 131 are arranged on the upper side surface of the outer fire cover body 11. An outer ring air groove 14 communicating with both the outer fire holes 12 and the gap fire holes 131 is arranged on the lower side of the fire cover body. The upper side surface of the outer fire cover body 11 includes an outer side surface 111 and an inner side surface 112. The inner side surface 112 is inclined downward from outside to inside, and the gap fire holes 131 are arranged between the outer side surface 111 and the inner side surface 112.
[0042] The burner provided by the present invention has a slit fire hole 131 provided on the upper side of the outer fire cover 1, so that a ring of slit fire is added between the inner ring fire and the outer ring fire, thereby improving the uniformity of the flame distribution of the burner, and further improving the uniformity of heating of the cooking pot. By providing an inner side surface 112 that is inclined downward from outside to inside, on the one hand, a negative pressure area can be formed at the inner side surface 112, which is beneficial for the secondary air in the secondary air passage 100 to move upward along the inner side surface 112 that is inclined downward from outside to inside to supplement the secondary air required for the combustion of the slit fire hole 131. On the other hand, it can also improve the easy-to-clean performance of the fire cover. The overflow liquid generated during cooking can flow downward along the inner side surface 112 that is inclined downward from outside to inside to the liquid receiving tray of the stove, preventing the overflow liquid from dripping onto the slit fire hole 131. On the third hand, it can improve the thermal efficiency of the burner. The high-temperature heat of the burner radiates part of the heat to the bottom of the cooking pot through the inner side surface 112 that is inclined downward from outside to inside.
[0043] Optionally, a slit groove 13 with an upward opening is provided between the outer side surface 111 and the inner side surface 112, and the slit fire hole 131 is provided at the bottom of the slit groove 13, which has a flame stabilizing effect to improve the flame stability at the slit fire hole 131.
[0044] Optionally, the slit groove 13 is inclined outward from top to bottom, so that the flame at the slit fire hole 131 can extend inward, thereby increasing the contact area with the air in the secondary air passage and improving the combustion efficiency.
[0045] Optionally, the outer side surface 111 is inclined downward from inside to outside to facilitate the flow of the overflow liquid during cooking.
[0046] Optionally, a stir-fry fire hole 23 is provided on the upper side of the inner fire cover body 21, and a stir-fry air groove 24 located inside the inner ring air groove 25 is also provided on the lower side of the inner fire cover body 21. The stir-fry air groove 24 is communicated with the stir-fry fire hole 23. By providing the stir-fry fire hole 23, on the one hand, the stir-fry function is realized. On the other hand, when the stir-fry function is started, the user can intuitively see that the flame range increases, thereby improving the user experience. On the third hand, by providing the stir-fry fire hole 23 on the upper side of the inner fire cover body 21, the stir-fry flame can be concentrated at the bottom of the cooking pot, solving the problem in the prior art that by increasing the length of the inner ring flame and the outer ring flame to increase the firepower, the flame further deviates from the bottom of the pot after the flame length is increased, resulting in poor stir-fry effect.
[0047] Optionally, it further includes a gas supply base 3 disposed under the outer fire cover 1 and the inner fire cover 2. The gas supply base 3 includes a base body 31, and a stir-fry gas chamber 34, an inner ring gas chamber 33, and an outer ring gas chamber 32 are formed on the base body 31. The stir-fry gas chamber 34 is formed inside the inner ring gas chamber 33, the outer ring gas chamber 32 is adjacent to the inner ring gas chamber 33, and the stir-fry gas chamber 34 communicates with the stir-fry gas groove 24 to form a stir-fry air passage. The inner ring gas chamber 33 communicates with the inner ring gas groove 25 to form an inner ring air passage, and the outer ring gas groove 14 communicates with the outer ring gas chamber 32 to form an outer ring air passage. In this way, the gas can directly enter the outer ring gas groove 14 through the outer ring gas chamber 32 to supply gas to the outer ring fire holes, reducing the pressure loss of the gas and air mixture, increasing the primary air coefficient, enabling the gas to mix with more air, and improving the combustion efficiency.
[0048] In this embodiment, to prevent the pressure of the air and gas mixture flowing from the outer ring gas chamber 32 to the outer ring gas groove 14 from being too high, so that the air and gas mixture can be more evenly distributed in the outer ring gas groove 14 and improve the distribution uniformity of the gas and air mixture at the outer fire holes 12, a partition sheet 6 is provided between the outer ring gas groove 14 and the outer ring gas chamber 32, and a plurality of through holes 61 are formed on the partition sheet 6 to achieve a certain degree of blocking and guiding of the air and gas mixture at this position.
[0049] Optionally, it further includes an ejector assembly 4 and a stir-fry pipeline 5. The ejector assembly 4 includes an outer ejector pipe 41 and an inner ejector pipe 42. The outer ejector pipe 41 extends horizontally and communicates with the outer ring gas chamber 32, the inner ejector pipe 42 extends horizontally and communicates with the inner ring gas chamber 33, and the stir-fry pipeline 5 communicates with the stir-fry gas groove 24.
[0050] Optionally, a gap is provided between the inner fire cover body 21 and the outer fire cover body 11 to form a secondary air passage 100.
[0051] Optionally, an ignition hole is further formed on the inner fire cover body 21, and the inner ring fire is ignited through the ignition hole.
[0052] Optionally, a fire transfer groove is further provided on the outer fire cover body 11. The fire transfer groove communicates the secondary air passage with the outside of the outer fire cover body 11, and fire transfer holes communicating with the outer ring gas groove 14 are formed on the fire transfer groove. The gas in the outer ring gas groove 14 enters the fire transfer groove through the fire transfer holes, and the inner ring fire is transferred to the outer fire holes 12 through the fire transfer groove to form an outer ring fire.
[0053] Embodiment Two
[0054] Please refer to Figures 8-11, The difference between the second embodiment and the first embodiment is that the base body 31 is successively provided with a stir-fry gas chamber 34, an inner ring gas chamber 33 and an outer ring gas chamber 32 from inside to outside. The base body 31 is also provided with a communicating airway 35 extending from inside to outside. The inner end of the communicating airway 35 is communicated with the upper end of the outer ring gas chamber 32. An air mixing groove 36 with an upward opening and communicated with the outer end of the communicating airway 35 is opened outside the base body 31. The stir-fry gas chamber 34 is communicated with the stir-fry gas groove 24 to form a stir-fry airway. The inner ring gas chamber 33 is communicated with the inner ring gas groove 25 to form an inner ring airway. The outer ring gas chamber 32 is communicated with the communicating airway 35 to form an outer ring airway. The outer ring gas groove 14 is communicated with the air mixing groove 36 to form an outer ring air mixing chamber. In this embodiment, the gas successively flows through the outer ejector tube 41, the outer ring gas chamber 32, the communicating airway 35, and the mixing chamber and then enters the outer fire holes 12 for combustion. During this process, after the gas and air flow and impact in multiple directions, the mixing uniformity is relatively high, which can also improve the combustion efficiency. On the other hand, it can also prevent the air pressure of the mixed gas of air and gas from being too high, resulting in the uneven height of the outer ring flame, making the combustion of the outer ring fire more stable.
[0055] On the other hand, the present invention provides a gas stove, which is characterized by including the above-mentioned burner.
[0056] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can be made, and these all belong to the protection scope of the present invention.
