DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 18As shown, a gas stove core includes a stove mechanism 6, and the stove mechanism 6 includes a stove head 8. The stove head 8 is located in the combustion chamber 5 and directly below the stove 2. The stove mechanism 6 can pass gas, and the gas can be ignited through the stove head 8 to heat the stove 2.

[0039] like Fig.12 and Fig.15 As shown, the stove head 8 includes a fire gathering ring 81, and a plurality of combustion holes 82 are provided on the side of the fire gathering ring 81. The gas chamber 75 is connected with the inside of the fire gathering ring 81 through the combustion holes 82. The fire gathering ring 81 is a conical structure with a larger upper part and a smaller lower part. The combustion holes 82 are inclined in the horizontal plane, and the combustion holes 82 are perpendicular to the side walls of the fire gathering ring 81 in the vertical plane. With the above structure, when the gas is ignited, the flame ejects from the combustion hole 82 and rises in a spiral shape, and has better contact with the air. Not only is the combustion and fire gathering effect good, but also cooperates with the guide rib group 23 of the stove 2, so that the flame divergence range is farther when the fire is fierce, which greatly improves the heating speed and heating uniformity of the stove 2.

[0040] like Fig.12 and Fig.14 As shown, an annular rib 86 and an igniter 84 are provided at the bottom of the fire gathering ring 81, the air intake pipe 74 is located on the periphery of the annular rib 86, an ignition plate 83 is provided inside the annular rib 86, the ignition position of the igniter 84 is located above the ignition plate 83, the ignition plate 83 and the annular rib 86 are connected by a connecting rib 87, and by providing the igniter 84, the gas in the fire gathering ring 81 can be ignited, and the gas ignition method is a prior art, and its specific structure will not be repeated in this specification.

[0041] A branch pipe 64 is connected to the side of the air pipe 63, and a three-way pipe 65 is provided inside the gas pipe 61 near the stove head 8, one end of the three-way pipe 65 is connected to the branch pipe 64, one end is inserted into the area surrounded by the annular rib 86 and is located below the ignition plate 83, and the remaining end is located in the gas pipe 61. A downwardly protruding arc platform is provided at the lower part of the ignition plate 83, one end of the three-way pipe 65 is located below the arc platform, and an ignition hole 85 is provided on the peripheral side of the arc platform and is inclined toward the center of the ignition plate 83. When in use, a part of the gas and air will converge in the three-way pipe 65, and the converged gas directly enters the bottom of the ignition plate 83 and enters the top of the ignition plate 83 from the ignition hole 85, and this part of the gas is ignited by the igniter 84. The gas and air are gathered through the three-way pipe 65 and the gathered gas is ignited, which can effectively ensure the ignition of the gas and solve the problem of ignition failure.

[0042] A sleeve 62 is sleeved on the outside of the gas pipe 61, and a gas channel 66 is provided between the gas pipe 61 and the sleeve 62. The air pipe 63 is connected to the gas channel 66, and the gas channel 66 is connected to the air inlet cavity 76. When the gas is ignited, the temperature in the combustion chamber 5 will be much higher than the temperature of the household gas stove. The high temperature is easily transmitted to the gas pipe 61, which can easily cause a fire in the gas pipe 61 and cause a safety accident. By providing the sleeve 62, the part of the gas pipe 61 close to the stove head 8 can be wrapped. When the gas is ignited, the normal temperature air in the combustion chamber 5 will be quickly heated. The normal temperature air can exchange heat with the gas pipe 61 in the gas channel 66, which can not only effectively reduce the temperature of the gas pipe 61, prevent the gas pipe 61 from catching fire and improve safety, but also preheat the air in advance and improve energy utilization.

[0043] like Figures 11 to 13 and Figures 16 to 18 As shown, the upper portion of the air inlet cavity 76 is an annular opening, and an air supply ring 9 is installed in the annular opening. The air supply ring 9 includes a plurality of air supply pipe groups 92, and the air supply pipe group 92 is connected to the air inlet cavity 76. The air supply ring 9 can rotate about the axis of the annular opening. Specifically, the air supply ring 9 includes a rotating plate 91, and the air supply pipe group 92 is installed on the upper portion of the rotating plate 91 and is evenly distributed along the axis of the rotating plate 91. An air guide plate 93 is provided between two adjacent air supply pipe groups 92, and the air guide plate 93 is fixed at the lower portion of the rotating plate 91. The air guide plate 93 is located in the air inlet cavity 76, a first annular notch 77 is provided on the inner side of the protective sleeve 72, and a second annular notch 78 is provided on the outer side of the lining 73, the outer ring of the rotating plate 91 is inserted into the first annular notch 77 and the inner ring is inserted into the second annular notch 78.

[0044] By setting the first annular notch 77 and the second annular notch 78, not only can the air supply ring 9 be installed and limited, but also the rotation of the air supply ring 9 can be facilitated. When the fire is slow, the air entering the air inlet chamber 76 is small and the flow rate is slow, so the air supply ring 9 cannot be driven to rotate, and the air supply ring 9 is stationary. Since the air inlet pipe 74 is located directly above the gas channel 66, most of the air will flow from the air inlet pipe 74 to the fire gathering ring 81, so that the gas in the fire gathering ring 81 can fully contact with the air, ensuring the combustion effect and making full use of the air. A small part of the air will enter the combustion chamber 53 from the air supply pipe group 92;

[0045] When stir-frying over high heat, the pressure in the air inlet chamber 76 will increase due to the large air flux. Since the air needs to pass through the air supply pipe group 92 to the combustion chamber 53, the air will push the air guide plate 93 after contacting the air guide plate 93, thereby driving the air supply ring 9 to rotate. When the air supply ring 9 rotates, the gas flowing out of the air supply pipe group 92 can form a rotating upward trend, and then cooperate with the arc-shaped bottom of the stove 2 to quickly distribute the air in the combustion chamber 53, so that the gas is fully in contact with the air, which greatly improves the combustion effect and efficiency of the gas, thereby achieving rapid heating of the stove 2 and achieving the effect of white coal combustion through gas combustion.

[0046] The air supply pipe group 92 is tilted in the horizontal plane, and the air guide plate 93 is an arc-shaped plate. The air guide plate 93 is tilted, and the connecting edge of the air guide plate 93 and the rotating plate 91 is located between two adjacent air supply pipe groups 92 and the other edge of the air guide plate 93 is located below the lower opening of the air supply pipe group 92. By setting the arc-shaped and tilted air guide plate 93, the air can more easily push the air supply ring 9 to realize the rotation of the air supply ring 9.

[0047] The air supply pipe group 92 includes a first air supply pipe 921, a second air supply pipe 922 and a third air supply pipe 923 which are arranged in sequence from the outside to the inside. The heights of the first air supply pipe 921, the second air supply pipe 922 and the third air supply pipe 923 are successively reduced. The first air supply pipe 921 and the third air supply pipe 923 are straight-through pipes. The upper end of the second air supply pipe 922 is provided with a first air supply port 924, and the side of the second air supply pipe 922 is provided with a plurality of second air supply ports 925. By arranging the first air supply pipe 921, the second air supply pipe 922 and the third air supply pipe 923 which are arranged in sequence from the high to the low, air can be supplied to the first air supply pipe 921, the second air supply pipe 922 and the third air supply pipe 923. The layered outflow makes the air distribution more uniform, and by arranging the first air supply port 924 and the second air supply port 925 in the second air supply pipe 922, the vertical air outlet and the peripheral air outlet of the second air supply pipe 922 can be realized, and the gas of the peripheral air outlet intersects and mixes with the gas of the first air supply pipe 921 and the second air supply pipe 922, which effectively avoids the problem of fast air flow rate at the outlets of the first air supply pipe 921, the second air supply pipe 922 and the third air supply pipe 923 and insufficient contact with the gas due to the large air intake, greatly improves the combustion effect of large-flow gas, and realizes rapid heating of the stove 2.

[0048] like Figure 1 and Figure 2As shown, it includes a base 1, a shell 11 is provided on the upper part of the base 1, a combustion chamber 5 and a stove mechanism 6 are provided inside the shell 11, a stove 2 is covered on the upper part of the shell 11, and the lower part of the stove 2 is located in the combustion chamber 5, a support column 12 is provided on the upper part of the base 1, a support frame 14 is provided on the upper part of the support column 12, the support frame 14 is L-shaped, a stirring mechanism 3 is installed at the lower part of the horizontal section of the support frame 14, the stirring mechanism 3 can be inserted into or separated from the stove 2, the support frame 14 is rotatably connected to the support column 12 through a rotating shaft 13, and the support frame 14 is driven to rotate by a first oil cylinder 17, and the two ends of the first oil cylinder 17 are respectively hinged to the support column 12 and the support frame 14.

[0049] The stirring mechanism 3 can rotate, which is a prior art. When food needs to be cooked, the stove 2 is heated, and the first oil cylinder 17 drives the support frame 14 to rotate, so that the stirring mechanism 3 is inserted into the stove 2. The food in the stove 2 is stirred by rotating the stirring mechanism 3, so that the food is heated more evenly.

[0050] A support plate 15 is provided on the upper part of the base 1, and a movable plate 16 is hinged on the upper part of the support plate 15. The movable plate 16 is fixedly connected to the stove 2. The movable plate 16 can rotate so that the stove 2 can be inserted into or separated from the combustion chamber 53. The second oil cylinder 18 drives the movable plate 16 to rotate. One end of the second oil cylinder 18 is hinged to the base 1 and the other end is hinged to the movable plate 16. When the food is cooked, the second oil cylinder 18 drives the stove 2 to flip over, so as to take out the food in the stove 2.

[0051] like Figures 3 to 7 As shown, the combustion chamber 5 includes an annular seat 51 and an exhaust pipe 56. An annular baffle 52 is provided on the upper portion of the annular seat 51. A combustion chamber 53 is provided inside the annular baffle 52. The stove 2 is inserted into the combustion chamber 53. A ventilation chamber 112 is formed between the outer side of the annular baffle 52 and the shell 11. There are three exhaust pipes 56, which are evenly distributed along the center of the combustion chamber 5. An air inlet 561 and a first air outlet 562 are respectively provided at both ends of the exhaust pipe 56. The air inlet 561 is communicated with the combustion chamber 53, and the first air outlet 562 is communicated with the ventilation chamber 112. The combustion chamber 53 is communicated with the ventilation chamber 112 through the exhaust pipe 56. A vent 113 is provided on the side of the shell 11. The vent 113 is communicated with the ventilation chamber 112, and the vent 113 is communicated with the outside.

[0052] When it is necessary to simmer the ingredients in the stove 2 over low heat, the stove head 8 is in low heat state. At this time, the stove mechanism 6 passes a small amount of gas and air into the combustion chamber 53. After the air enters the combustion chamber 53, it enters the corresponding exhaust duct 56 from the three air inlets 561, and then flows out from the corresponding first air outlet 562 to the ventilation chamber 112, and is discharged to the outside through the vent 113. When in the low heat state, there are only three air outlets in the combustion chamber 5, which is a very small number. While satisfying the ventilation, by reducing the number of air outlets, the heat loss in the combustion chamber 5 is reduced, thereby reducing the energy loss.

[0053] like Figure 7 As shown, the exhaust duct 56 includes a coil 563, and the air inlet 561 and the first air outlet 562 are two ports of the coil 563. The coil 563 is close to the inner wall of the annular partition 52, and the coil 563 is located at the periphery of the stove 2. Since the stove 2 is of industrial grade specification, the weight of food processing can reach five tons at a time, and the diameter is large. Therefore, when simmering over a low fire, the side wall and the bottom of the stove 2 are far away from the contact point with the flame, and the side wall temperature of the stove 2 is much lower than the bottom temperature of the stove 2. Therefore, by setting the coil 563, while ventilation is being carried out, hot air enters from the air inlet 561, and can heat the coil 563 after passing through the coil 563. Through heat conduction between the coil 563 and the stove 2, the temperature difference between the side wall of the stove 2 and the bottom of the stove 2 can be effectively reduced, thereby effectively improving the cooking effect of the food.

[0054] like Figures 5 to 7 As shown, the annular partition plate 52 is provided with a plurality of second air outlets 57 on the circumferential side thereof, and the combustion chamber 53 and the ventilation chamber 112 can be communicated with each other through the second air outlets 57; the outer wall of the annular partition plate 52 is provided with a cover plate 59 corresponding to the second air outlet 57, and the cover plate 59 can cover the second air outlet 57; the cover plate 59 is hinged to the annular partition plate 52 through a hinge seat 58, and the hinge seat 58 is located above the second air outlet 57; the cover plate 59 is a metal plate, and when the air pressure in the combustion chamber 53 increases, the cover plate 59 can be pushed to rotate, so that the combustion chamber 53 and the ventilation chamber 112 can be communicated with each other through the second air outlet 57.

[0055] When stir-frying over high heat, a large amount of gas and air enter the combustion chamber 53, and the air temperature in the combustion chamber 53 is high. At this time, the exhaust effect cannot be satisfied through the exhaust duct 56. The combustion chamber 53 is affected by the high heat and large air flow, and its internal pressure increases, which can push the cover plate 59 to rotate along the hinge seat 58. The second air outlet 57 opens, and the air in the combustion chamber 53 can be discharged from the first air outlet 562 and the second air outlet 57, thereby effectively ensuring the air circulation in the combustion chamber 5, not only ensuring the full combustion of the gas, but also reducing the heat loss of the side wall of the stove 2 through the coil 563, so that the stove 2 is heated more evenly and the heating speed is faster.

[0056] An annular platform 111 is fixed to the upper part of the shell 11, the upper end of the annular partition 52 abuts against the lower part of the annular platform 111, the side wall of the stove 2 is gap-matched with the annular platform 111, and a supporting platform 22 is fixed to the side wall of the stove 2, and the lower part of the supporting platform 2 can abut against or detach from the upper part of the annular platform 111. By setting the annular platform 111, not only can the stove 2 be supported, but also the airtightness of the ventilation cavity 112 can be improved to reduce heat loss.

[0057] like Figure 5 As shown, a first mounting groove 54 and a second mounting groove 55 are provided inside the combustion chamber 53, the stove head 8 is installed in the first mounting groove 54, a first thermal insulation cotton 100 is provided in the second mounting groove 55, and a second thermal insulation cotton 200 is provided on the inner wall of the ventilation cavity 112 located at the shell 11, and the first thermal insulation cotton 100 and the second thermal insulation cotton 200 are quartz wool.

[0058] A heat preservation chamber 114 is provided between the shell 11 and the combustion chamber 5 , and the heat preservation chamber 114 is isolated from the ventilation chamber 112 by the annular seat 51 . The heat preservation chamber 114 can not only prevent scalding, but also improve the heat preservation effect of the combustion chamber 53 .

[0059] An exhaust mechanism 4 is provided on the side of the shell 11, and the exhaust mechanism 4 includes an exhaust box 41. An exhaust pipe 42 is provided on the upper part of the exhaust box 41. An insulating sleeve 43 is provided on the outer side of the exhaust pipe 42. The vent 113, the exhaust box 41 and the exhaust pipe 42 are connected. The air in the combustion chamber 53 is discharged to the outside through the exhaust pipe 42. By providing the insulating sleeve 43, it can play a role in heat insulation and scalding prevention.

[0060] like Figure 1 As shown, a discharge port 21 is provided on the side of the stove 2 . When the stove 2 is turned over, the discharge port 21 can be tilted, and the food in the stove 2 can be taken out from the discharge port 21 .

[0061] like Figure 4 , Figure 8 and Fig. 9As shown, an arcuate convex ring 24 is provided at the bottom of the stove 2, and an arcuate groove 25 is provided inside the arcuate convex ring 24. The stove head 8 is located directly below the arcuate convex ring 24. A plurality of guide rib groups 23 extending outward along the bottom surface of the stove 2 are provided on the circumference of the arcuate convex ring 24. By providing the arcuate convex ring 24, not only the thickness of the bottom of the stove 2 can be increased to prevent the stove 2 from deforming during use, but also when the fire is low, the flame can be more concentrated at the bottom of the stove 2, solving the problem of excessive heat loss due to flame dispersion when the fire is low, and when the fire is high, it can play a guiding role, so that the flame can be guided to the side wall of the stove 2 along the guide rib group 23, thereby increasing the heating range of the stove 2, thereby greatly improving the heating effect of the stove 2. By providing the guide rib group 23, not only can the flame and gas be guided, but also the structural strength of the stove 2 can be improved, and the service life of the stove 2 can be improved.
