The top end 2-7-1 of the inner pillar 2-7 passes through the middle layer inner mounting hole 6-5-1 to be abutted against the bottom end of the upper layer inner ring mounting folded edge 1-7. Through the design of the middle layer inner vertical folding edge 6-6 and the middle layer inner bottom folding edge 6-7, the stability of the middle layer inner mounting hole 6-5-1 sleeved on the inner support post 2-7 is improved, the inner support post is not easy to fall off, and therefore the connection stability of the middle layer inner mounting folding edge 6-5 and the lower layer inner ring mounting folding edge 2-5 is improved.
Therefore, due to the support of the inner support columns 2-7, the space is reserved between the middle layer inner mounting folding edge 6-5 and the upper layer inner ring mounting folding edge 1-7, and therefore heat transfer between the middle layer inner mounting folding edge and the upper layer inner ring mounting folding edge is reduced. Namely, the upper inner ring mounting flange 1-7, the inner vertical ring flange 1-8 and the inner bottom annular flange 1-9 form a U shape with an outward opening, the middle inner mounting flange 6-5, the middle inner vertical flange 6-6, the middle inner bottom flange 6-7, the lower inner ring mounting flange 2-5 and the inner pillar 2-7 are surrounded, the upper inner ring mounting flange 1-7, the inner vertical ring flange 1-8 and the inner bottom annular flange 1-9 are not directly contacted with the lower inner ring mounting flange 2-5, point contact is realized through the inner pillar 2-7, the heat conduction contact area of the upper energy gathering ring 1, the middle energy gathering ring 6 and the lower energy gathering ring 2 is reduced, and the integral attractiveness is improved.
In the embodiment, a plurality of supporting claws 4 are arranged on the upper-layer outer ring mounting flange 1-4 at intervals along the circumferential direction and used for placing a pot; the lower layer outer ring installation folded edge 2-4, the middle layer outer ring installation folded edge 6-4, the upper layer outer ring installation folded edge 1-4 and the support claw 4 are connected through a fastener 5 (such as a bolt, a screw and the like), so that the support claw 4 is stably and reliably connected with the lower layer outer ring installation folded edge 2-4, the middle layer outer ring installation folded edge 6-4 and the upper layer outer ring installation folded edge 1-4, and is convenient to disassemble and assemble. The plurality of supporting claws 4 correspond to the plurality of upper layer outer mounting holes 1-4-1 one by one, the supporting claws 4 are positioned above the corresponding upper layer outer mounting holes 1-4-1, and the plurality of fasteners 5 sequentially penetrate through the corresponding lower layer outer mounting holes 2-4-1, the middle layer outer mounting holes 6-4-1, the upper layer outer mounting holes 1-4-1 and the supporting claws 4 from bottom to top. Moreover, the fastening piece 5 is surrounded and shielded by the outer vertical annular folded edge 1-5 and the outer bottom annular folded edge 1-6, so that the attractiveness of the energy gathering ring is improved.
The supporting claw 4 is made of metal materials such as brass, cast iron, stainless steel and aluminum alloy, so that the strength is ensured, and meanwhile, the supporting claw 4 is provided with a plurality of teeth, so that the cooker can be prevented from sliding after being placed on the supporting claw 4.
The material of the upper-layer energy-gathering ring 1 is stainless steel, aluminum alloy and the like, and the stainless steel is preferred in consideration of convenience in machining and forming. Meanwhile, the stainless steel has lower heat conductivity, and can reduce the heat transfer with the energy-gathering rings of the middle and lower layers.
The material of the middle-layer energy-gathering ring 6 can be aerogel, stainless steel, aluminum alloy and the like, preferably, the aerogel has extremely low thermal conductivity of about 0.013W/(m/K), and the heat transfer with the lower-layer energy-gathering ring 2 can be effectively reduced.
The material of the lower energy gathering ring 2 is stainless steel, aluminum alloy, cast iron and the like, and the aluminum alloy is preferred in consideration of convenient processing and forming. The material of the fastening piece 5 is preferably stainless steel, so that the heat of the supporting claws 4 cannot be rapidly transferred to the upper-layer energy gathering ring 1.
In this embodiment, the height of the support claw 4 is 5mm to 15 mm. The height of the supporting claw 4 is the height of the supporting claw 4 protruding out of the upper layer outer ring installation folded edge 1-4. The height range of the supporting claws 4 can ensure that the annular gap is formed between the upper layer outer ring mounting folded edge 1-4 and the bottom of the cookware, and the height of the gap is the same as that of the supporting claws 4. If the height of the gap is too small, the high-temperature smoke discharge resistance is too large; if the height of the gap is too large, certain resistance cannot be formed on high-temperature flue gas, the height of the gap is controlled to be 5-15 mm, and certain resistance can be formed on the high-temperature flue gas discharged from a fire hole of the outer fire cover 7, so that the high-temperature flue gas collides with the outer annular inclined plane 1-1 of the upper layer and then contacts the annular bottom surface 1-2 of the upper layer, and then collides with the high-temperature flue gas just discharged from the fire hole through the guiding effect of the inner annular inclined plane 1-3 of the upper layer, the collision process reduces the speed of the flue gas, the retention time of the high-temperature flue gas above the upper layer energy-gathering ring 1 is further prolonged, secondary combustion of the high-temperature flue gas above the upper layer energy-gathering ring 1 is realized, and the heat exchange efficiency of the high.
The bottom of the lower energy-gathering ring 2 is provided with a plurality of supporting legs 2-8, the supporting legs 2-8 are contacted with the liquid containing disc 9, and the energy-gathering ring and the outer fire cover 7 are concentrically arranged; the position without fire holes on the periphery of the outer fire cover 7 is called a vacant position 7-3, and the supporting claws 4 correspond to the vacant position 7-3 of the outer fire cover 7, so that the supporting claws 4 cannot be burnt when the outer fire cover 7 is fired.
The inner diameter of the energy-gathering ring is 2-20 mm larger than the outer diameter of the outer fire cover 7; the inner vertical annular folded edge 1-8 is the part with the smallest diameter of the energy gathering ring, so the inner diameter of the energy gathering ring refers to the inner diameter of the inner vertical annular folded edge 1-8, and the inner diameter of the inner vertical annular folded edge 1-8 is 2-20 mm larger than the outer diameter of the outer fire cover 7. The inner edge of the energy gathering ring is 2mm-10mm lower than the fire hole 7-1 of the outer fire cover 7, namely the top end of the inner edge of the inner vertical annular folded edge 1-8 is 2mm-10mm lower than the fire hole 7-1 of the outer fire cover 7. Through the adjustment of the two parameters, the heat of the flame can be effectively isolated on the upper-layer energy accumulation ring 1, meanwhile, the flame sprayed out from the fire hole 7-1 of the outer fire cover 7 sucks secondary air from the bottom of the energy accumulation ring (injection effect, see the dotted arrow in fig. 10) through the gap between the energy accumulation ring and the outer fire cover 7, and the secondary air can directly reach the fire hole 7-1 of the outer fire cover 7, so that the full combustion of the fuel gas sprayed out from the outer fire cover 7 is ensured. Meanwhile, a plurality of secondary air channels 7-2 are formed on the inner peripheral wall of the outer fire cover 7 at intervals along the circumferential direction, and as shown in fig. 9, the secondary air supplements the flame of the inner fire cover 8 through the secondary air channels 7-2, so that the full combustion of the inner ring flame is ensured.
The energy gathering ring of this embodiment, through reducing the area of contact of upper energy gathering ring 1 and lower floor energy gathering ring 2, design a plurality of subcavities 3-1 and a claw 4 and fix etc. alone, reduced the heat-conduction between upper energy gathering ring 1 and middle level energy gathering ring 6, lower floor energy gathering ring 2, improved the thermal efficiency of cooking utensils.
