Description

Existing stoves, such as an invention patent with publication number CN118258040A, include a stove body, an inner tank connected to the stove body, and an ash receiving tray arranged at intervals below the inner tank. A combustion chamber is formed in the inner tank, an ash leakage hole is provided at the bottom of the inner tank, and an air inlet for external gas to enter the stove body is provided at the lower end of the side wall of the stove body. When in use, the negative pressure generated by the combustion of fuel in the combustion chamber can be utilized to allow external air to enter the combustion chamber from the air inlet, the interval gap between the ash receiving tray and the inner tank, and the ash leakage hole in sequence to mix with the fuel and help the fuel burn.

[0031] like Figure 1-Figure 9As shown, as an embodiment of the present invention, a fully combustion-supporting stove is provided, comprising a combustion structure 1, a support structure 2, an air guide structure 3 capable of adjusting the air volume, an ash tray 4, and a grate 5 located directly above the ash tray. The combustion structure 1 has an inner cavity structure 11, an outer cavity structure 12, and a combustion chamber, which is defined inwardly by the inner cavity structure 11 and is used for burning fuels such as firewood and charcoal. The support structure 2 is detachably connected to the lower part of the combustion structure 1, and the support structure 2 includes a support foot 21 for being placed on a support interface such as the ground or a floor surface, and a notch is provided along the wall of the support structure 2 between adjacent support feet 21, and an air inlet channel 20 is formed by the notch, and the air inlet channel 20 is used for allowing external air to flow into the lower part of the air guide structure 3. The air guide structure 3 is arranged directly below the combustion chamber and connected to the support structure 2, and the air guide structure 3 is provided with a plurality of air guide channels 30 along the circumferential direction, which are used for introducing the air directly below the air guide structure 3 into the combustion structure 1. The ash pan 4 is connected to the upper part of the air guide structure 3 through the first connecting structure 6. The ash pan 4 is provided with a plurality of ventilation holes 421 along its side wall. The grate 5 is movably placed on the ash pan 4 for supporting the fuel. The grate 5 is provided with a plurality of air outlet holes 51 for introducing air into the combustion chamber. The grate 5 is also provided with ash leakage holes 52 for introducing the ash after the fuel is burned into the ash pan 4. The air outlet holes 51 and the ash leakage holes 52 can be set as the same hole or as different holes. It also includes a first guide path group 100 for allowing external air to enter the combustion chamber for combustion assistance, a second guide path group 200 with an air outlet located above the air outlet of the first guide path group 100, and a third guide path group 300 with an air outlet located above the air outlet of the second guide path group 200, so that the fuel is mixed with the air introduced into the combustion chamber by the first guide path group 100 for primary combustion, and at the same time, a large amount of fuel debris and carbon monoxide and other combustibles generated during the primary combustion process rise under the impetus of the combustion airflow, and are mixed with the air introduced into the combustion chamber by the second guide path group 200 for secondary combustion, and at the same time, a small amount of fuel debris and carbon monoxide and other combustibles omitted during the secondary combustion process continue to rise under the impetus of the combustion airflow, and are mixed with the air introduced into the combustion chamber by the third guide path group 300 for tertiary combustion, thereby realizing secondary and tertiary combustion assistance, so that the fuel can burn more fully and thoroughly, thereby improving the combustion firepower and combustion efficiency of the fuel, and greatly reducing the emission of harmful smoke;In addition, the ventilation holes 421 are arranged on the first flow guide path group 100, the air outlet holes 51 form the air outlet of the first flow guide path group 100, and the grate 5 is located directly above the ash pan 4. That is to say, the first flow guide path group 100 introduces air into the combustion chamber through the ventilation holes 421 on the side wall of the ash pan 4 and the air outlet holes 51 on the grate 5 for combustion support. Compared with the structure in the prior art in which air is introduced into the combustion chamber through the horizontal interval gap between the ash receiving pan and the inner tank and the ash leakage hole, the air of the present invention always flows upward during this part of the flow guide process. The resistance to air flow is smaller, which is more conducive to introducing enough air into the combustion chamber for combustion support, and the grate 5 can be movably placed on the ash tray 4, so that the grate 5 can be taken out separately to clean the air outlet of the first guide path group 100, which is convenient for cleaning; the air outlet of the second guide path group 200 is arranged around the middle of the combustion chamber, and the air outlet of the third guide path group 300 is arranged around the upper part of the combustion chamber, so that the air sucked into the combustion chamber through the air outlet of the second guide path group 200 and the air outlet of the third guide path group 300 can generate a vortex. The air flow effect is improved, thereby improving the mixing effect of air and fuel, fuel debris and combustibles such as carbon monoxide, so that the fuel can be burned more fully; the air guide structure 3 is arranged just below the combustion chamber, and the air guide structure 3 is provided with a plurality of air guide channels 30 along the circumferential direction. External air can enter the combustion structure through the air inlet channel 20 formed by the gap between adjacent supporting legs 21 and the air guide channel 30 on the air guide structure 3 just below the combustion chamber. Compared with the prior art in which the air inlet is directly arranged on the side wall of the furnace body, the present invention is less susceptible to the influence of external environmental factors such as wind direction, so that The air sucked into the combustion structure is more sufficient and uniform, and the combustion-supporting effect is better. The air guide structure 3 can adjust the air volume, which can meet the needs of different firepower sizes and has a wider range of applications. The support structure 2 is detachably connected to the lower part of the combustion structure 1, and the air guide structure 3 is connected to the support structure 2, and the ash pan 4 is connected to the upper part of the air guide structure 3 through the first connection structure 6, so that the ash pan 4, the air guide structure 3 and the support structure 2 can be disassembled relative to the combustion structure 1 as a whole, so as to facilitate the dumping of the ash in the ash pan 4, which is very convenient to use. ;

[0032] like Figure 3As shown, in some specific embodiments, the first flow guide path group 100 includes a first path a formed by entering from the notched air inlet channel 20 and passing through the air guide channel 30 to pass through the air guide structure 3, and a second path b formed by extending from the top of the air guide structure 3 upward and along the area enclosed between the inner wall of the outer cavity structure 12 and the outer wall of the ash pan 4. The first path a is used to guide external air to enter from the air inlet channel 20 directly below the air guide structure 3, and enter the combustion structure 1 through the air guide channel 30. The second path b is used to guide the air entering the combustion structure 1 to flow upward along the inner wall of the outer cavity structure 12 and the outer wall of the ash pan 4. The width of the second path b gradually decreases from bottom to top, so that the wind force gradually increases from bottom to top, thereby being able to form a relatively large pressure difference with the combustion chamber, which is conducive to guiding the air to be injected into the combustion chamber, and the combustion-supporting effect is better.

[0033] like Figure 3 As shown, in some specific embodiments, the first flow guide path group 100 also includes a third path c arranged upward from the ventilation hole 421 of the ash pan 4 and passing through the grate 5 through the air outlet hole 51, and the air outlet hole 51 forms the air outlet of the first flow guide path group 100. The third path c is used to guide air into the ash pan 4 through the ventilation hole 421, and then into the combustion chamber through the air outlet hole 51. The ventilation hole 421 is arranged near the upper end of the side wall of the ash pan 4. On the one hand, the ventilation hole 421 guides air into the ash pan 4 at a position with strong wind force to ensure a good combustion-supporting effect. On the other hand, the distance between the ventilation hole 421 and the bottom of the ash pan 4 is large, and the distance between the ventilation hole 421 and the air outlet hole 51 is small, so that the ash in the ash pan 4 can be avoided from being blown up, and the air can also be quickly passed through the air outlet hole 51 to enter the combustion chamber to support combustion after passing through the ventilation hole 421.

[0034] like Figure 3 , Figure 6As shown, in some specific embodiments, the ash pan 4 includes a pan bottom plate 41, a pan side plate 42 extending upward from the periphery of the pan bottom plate 41, and a pan edge structure 43 formed by turning the top of the pan side plate 42 outward, the pan edge structure 43 is sleeved in the inner cavity structure 11, and the grate 5 can be movably placed on the pan edge structure 43, so as to ensure that the fuel placed on the grate 5 remains burned in the combustion chamber, and can play a heat insulation role through the heat insulation cavity between the inner cavity structure 11 and the outer cavity structure 12, thereby preventing the operator from being burned when touching the outer cavity structure 12. The disk edge structure 43 is not in contact with the inner cavity structure 11, and the outer diameter of the disk edge structure 43 is smaller than the inner diameter of the inner cavity structure 11, so as to form a fitting gap 40 between the disk edge structure 43 and the inner cavity structure 11, and the width of the fitting gap 40 is set to 0.5-2mm, which is used to prevent the combustion structure 1 or the ash pan 4 from being unable to be installed in the inner cavity structure 11 due to thermal expansion and contraction, wherein the width of the fitting gap 40 is preferably 1.5mm, which can prevent the ash pan 4 from being unable to be installed in the inner cavity structure 11 due to thermal expansion and contraction, while preventing a large amount of air from directly entering the combustion chamber through the fitting gap 40, thereby affecting the air guide effect of the first guide path group 100 or the second guide path group 200 or the third guide path group 300.

[0035] like Figure 3 , Fig. 9As shown, in some specific embodiments, the air guide structure 3 has a middle area arranged directly below the disc bottom plate 41 and a surrounding area arranged around the middle area. A part of the air guide channel 30 is arranged in the middle area of ​​the air guide structure 3, and the disc bottom plate 41 is arranged above the air guide structure 3 at intervals. The first connection structure 6 includes a plurality of support feet 61 arranged between the disc bottom plate 41 and the air guide structure 3 along the circumferential direction, and a spacing area connected to the air guide channel 30 in the middle area is formed between each adjacent support foot 61. The air guide channel 30 located in the middle area can guide the air directly below the middle area of ​​the air guide structure 3 into the combustion structure 1, and diffuses laterally to the periphery along the upper side of the air guide structure 3 and the middle of the outer wall of the disc bottom plate 41, and flows upward along the inner wall of the outer cavity structure 12, the inner wall of the inner cavity structure 11, and the outer wall of the disc side plate 42 to the ventilation hole 1 421 or the ventilation hole 2 1141, or flows back to the ventilation hole 1 421 along the outer wall of the disc edge structure 43 and the inner wall of the inner cavity structure 11. Another part of the air guide channel 30 is arranged in the surrounding area of ​​the air guide structure 3. The air guide channel 30 located in the surrounding area can guide the air directly below the surrounding area of ​​the air guide structure 3 into the combustion structure 1, and flow upward along the inner wall of the outer cavity structure 12, the inner wall of the inner cavity structure 11, and the outer wall of the disk side plate 42 to the ventilation hole 1 421 or the ventilation hole 2 1141, or flow back along the outer wall of the disk edge structure 43 and the inner wall of the inner cavity structure 11 to the ventilation hole 1 421. In addition, the cold air entering from the outside can also exchange heat with the air guide structure 3, the disk bottom plate 41, the disk side plate 42, the disk edge structure 43, the inner cavity structure 11, and the outer cavity structure 12 when flowing along these, so that the cold air can be gradually converted into hot air that is more conducive to combustion, and these structures can also be cooled to avoid scalding the operator.

[0036] like Figure 3As shown, in some specific embodiments, the ventilation hole 421 is arranged on the disk side plate 42 near the disk edge structure 43, and the outer end surface of the disk bottom plate 41 includes a horizontal guide surface 411 arranged in the horizontal direction and an inclined guide surface 412 arranged around the periphery of the horizontal guide surface 411. The horizontal guide surface 411 can guide the air to enter the combustion structure 1 through the middle area air guide channel 30 and diffuse to the periphery in the horizontal direction. The inclined guide surface 412 is set as a conical structure, and the radius of the upper end of the inclined guide surface 412 is greater than the radius of the lower end, which can guide the air diffused to the periphery in the horizontal direction to flow upward obliquely. At the same time, compared with the area of ​​the circular area formed by the horizontal guide surface 411 and the inner wall of the outer cavity structure 12, the area of ​​the annular area formed by the inclined guide surface 412 and the inner wall of the outer cavity structure 12 is reduced, so that the pressure of the air in the process of flowing from bottom to top increases step by step. The disk side plate 42 is set as a conical structure, and the radius of the upper end of the disk side plate 42 is greater than the radius of the lower end, so that the pressure of the air in the process of flowing from bottom to top continues to increase step by step. The pan edge structure 43 includes a first supporting edge 431 formed by turning outward from the top of the pan side plate 42, a first limiting edge 432 formed by turning upward from the outer end of the first supporting edge 431, and a return edge 433 formed by turning outward from the first limiting edge 432. The grate 5 is placed on the upper side of the first supporting edge 431, and is limited by the first limiting edge 432 to move radially relative to the ash pan 4. The operator can directly move the grate 5 upward out of the ash pan 4 and then dump the ash in the ash pan 4. The return edge 433 has a return guide portion 4331 extending downward, and an air return area is formed between the disk edge structure 43, the inner cavity structure 11 and the disk side plate 42. Part of the air can press against the first supporting edge 431 after rising along the outer wall of the disk side plate 42, and flow outward laterally along the first supporting edge 431, then flow upward along the first limiting edge 432 and the inner cavity structure 11, and then flow downward along the return edge 433 and its return guide portion 4331 to form the air return area, so as to guide the rising air to flow back to the ventilation hole 421.

[0037] In some specific embodiments, the inner cavity structure 11 includes a lower inner cavity portion 111, a middle inner cavity portion 112, an upper inner cavity portion 113, a lower support table 114 formed by flanging outward along the bottom of the lower inner cavity portion 111, and an upper support table 115 formed by flanging outward along the top of the upper inner cavity portion 113. The lower support table 114 is arranged above the air guide structure 3 at intervals, and the outer end of the lower support table 114 is combined with the inner wall of the outer cavity structure 12, and the outer end of the upper support table 115 is combined with the outer cavity structure 12, so that an insulating cavity is formed around the inner cavity structure 11 and the outer cavity structure 12 to prevent the heat of the combustion chamber from being transferred to the outer cavity structure 12 and scalding the operator. The combination method can be welding or integral molding. A plurality of ventilation holes 1141 are provided through the lower support table 114 for air to enter the insulating cavity. By arranging the lower support table 114 at intervals above the air guide structure 3, the second path b is formed by the bottom surface of the lower support table 114, the inner wall of a portion of the outer cavity structure 12 below the lower support table 114, the inner wall of a portion of the lower inner cavity portion 111 below the reflux guide portion 4331, the outer wall of the ash tray 4, and the top surface of the air guide structure 3. The entire second path b has a larger range of motion, and the air guide structure 3 is arranged directly below the combustion chamber. By opening air guide channels 30 on various parts of the air guide structure 3, more air can be guided from the air guide structure 3 into the combustion structure 1.

[0038] like Figure 1 , Figure 3As shown, in some specific embodiments, the combustion structure 1 is configured as a cylindrical structure, which is conducive to the air sucked into the combustion chamber through the air outlet of the second guide path group 200 and the air outlet of the third guide path group 300 to produce a swirl effect. The outer cavity structure 12 includes an outer cavity body and a positioning member connected to the lower end of the outer cavity body, the positioning member is used to install and position in the installation area, the inner cavity structure is connected to the outer cavity body, the outer cavity body is configured as a conical structure, and the radius of the upper end of the outer cavity structure 12 is smaller than the radius of the lower end, which can gradually increase the pressure of the air flowing upward from bottom to top, so that the wind force at the outlet of the second guide path group 200 is greater than the wind force at the outlet of the first guide path group 100, and the wind force at the outlet of the third guide path group 300 is greater than the wind force at the outlet of the second guide path group 200, thereby being able to pass through the second guide path group 200 for secondary The combustion provides more air for combustion assistance than the first guide path group 100, and the third guide path group 300 provides more air for combustion assistance than the second guide path group 200 for the tertiary combustion, and because the temperature of the air becomes higher and higher due to the influence of the temperature in the combustion chamber during the upward flow of the air, the combustion assistance effect of the air introduced into the combustion chamber through the second guide path group 200 is better than the combustion assistance effect of the air introduced into the combustion chamber through the first guide path group 100, and the combustion assistance effect of the air introduced into the combustion chamber through the third guide path group 300 is better than the combustion assistance effect of the air introduced into the combustion chamber through the second guide path group 200.

[0039] In some specific embodiments, the circumference of the upper inner cavity 113 is greater than the circumference of the lower inner cavity 111, that is, the radius of the upper inner cavity 113 is greater than the radius of the lower inner cavity 111, and the lower end of the middle inner cavity 112 is combined with the lower inner cavity 111, and the upper end is combined with the upper inner cavity 113 to form a wedge-shaped structure with a small bottom and a large top. The middle inner cavity 112 is provided with a plurality of second air outlet holes 1121, and the second air outlet holes 1121 form the air outlet of the second guide path group 200. The upper inner cavity 113 is provided with a plurality of third air outlet holes 1131, and the third air outlet holes 1131 form the air outlet of the third guide path group 300. The combination method can be welding or integral molding. The wedge-shaped structure design, on the one hand, causes the wind force to gradually increase during the upward flow between the inner cavity structure 11 and the outer cavity structure 12, so that the combustion-supporting effect introduced into the combustion chamber through the third guide path group 300 is better than the combustion-supporting effect introduced into the combustion chamber through the second guide path group 200. On the other hand, it allows the air to more easily enter the air outlet hole 2 1121 on the middle inner cavity portion 112 after rising along the lower inner cavity portion 111, preventing the air from directly passing over the air outlet hole 2 1121 and only entering the combustion chamber from the air outlet hole 3 1131, thereby ensuring the effective combustion support of the second guide path group 200. In this embodiment, the middle inner cavity 112 is configured as a conical ring plate structure, and the outer diameter of the middle inner cavity 112 gradually increases from bottom to top, and the inner diameter of the middle inner cavity 112 gradually increases from bottom to top. The second air outlet 1121 is arranged in an inclined upward direction, so that air can be sprayed into the combustion chamber in an inclined upward direction, so that the swirling air in the combustion chamber flows upward in a spiral, which can further promote the full mixing of combustibles such as fuel, fuel debris and carbon monoxide with air, so that the fuel burns more fully and more thoroughly.

[0040] like Figure 3As shown, in some specific embodiments, the second flow guide path group 200 includes the first path a, the second path b, the fourth path d formed upward from the second ventilation hole 1141 of the lower support table 114 and along the area enclosed between the inner wall of the outer cavity structure 12 and the outer wall of the lower inner cavity part 111, and the fifth path e arranged upward and formed along the area enclosed between the inner wall of the outer cavity structure 12 and the outer wall of the middle inner cavity part 112. The fourth path d is used to guide air to enter the partition cavity formed by the inner cavity structure 11 and the outer cavity structure 12 through the second ventilation hole 1141, and flow upward along the outer wall of the lower inner cavity part 111 and the inner wall of the outer cavity structure 12. The fifth path e is used to guide air to flow upward along the outer wall of the middle inner cavity part 112 and the inner wall of the outer cavity structure 12, and part of the air flowing along the fifth path e can enter the combustion chamber through the second air outlet hole 1121. The width of the fourth path d is smaller than that of the second path b, so that the wind force in the fourth path d is greater than the wind force in the second path b. The width of the fifth path e gradually decreases from bottom to top to divert the flow, so that the wind force in the fifth path e gradually increases from bottom to top to be greater than the wind force in the fourth path d.

[0041] In some specific embodiments, the third flow guiding path group 300 includes the first path a, the second path b, the fourth path d, the fifth path e, and the sixth path f arranged upward and formed along the area enclosed by the inner wall of the outer cavity structure 12 and the outer wall of the upper inner cavity portion 113. The sixth path f is used to guide the air to flow upward along the outer wall of the upper inner cavity portion 113 and the inner wall of the outer cavity structure 12, and part of the air flowing along the sixth path f can enter the combustion chamber through the air outlet three 1131. The wind force in the sixth path f is greater than the wind force in the fifth path e.

[0042] like Figure 7As shown, in some specific embodiments, a fire gathering ring 7 is further included, and the fire gathering ring 7 is used to gather the air introduced into the combustion chamber through the air outlet of the third guide path group 300 in the fire gathering ring 7, so as to help the fire around the opening position of the combustion chamber burn more vigorously. The upper support table 115 includes a second support edge 1151 formed by turning the top of the upper inner cavity 113 outward, and a second limiting edge 1152 formed by turning the outer end of the second support edge 1151 upward, wherein the fire gathering ring 7 is placed on the upper side of the second support edge 1151, and is limited by the second limiting edge 1152 to move radially relative to the combustion structure 1, and the operator can directly move the fire gathering ring 7 upward out of the combustion structure 1 to selectively use or not use the fire gathering ring 7. Air outlet hole three 1131 is arranged on the upper inner cavity portion 113 near the upper support table 115, and an air recirculation area is formed around the upper support table 115, the upper inner cavity portion 113 and the outer cavity structure 12. Part of the air can rise along the outer wall of the upper inner cavity portion 113 and then press against the second support edge 1151, and flow downward under the rebound of the second support edge 1151 to guide the rising air to flow back to air outlet hole three 1131.

[0043] like Fig. 9 As shown, in some specific embodiments, the air guide structure 3 is arranged above the air inlet channel 20 to ensure that the external air can flow upward to the air guide channel 30 through the air inlet channel 20. The air guide structure 3 includes a support plate 31 and an adjustment plate 32 coaxially arranged on the lower side of the support plate 31. The outer peripheral side of the support plate 31 is combined with the inner side of the wall of the support structure 2. After the combination, the outer peripheral edge of the top of the support plate 31 and the inner side of the wall of the support structure 2 surround and form an installation area for movably placing the combustion structure 1. The combination method can be welding or integral molding. The installation area is arranged around the periphery of the surrounding area to ensure that the air guide channel 30 of the surrounding area can enter the combustion structure 1. The combustion structure 1 is placed on the support plate 31 as a whole, and is radially moved relative to the support structure 2 by the inner limit of the wall of the support structure 2. The operator can directly move the combustion structure 1 upward out of the support structure 2 as a whole and then dump the ash in the ash pan 4. The wall of the support structure 2 or the support foot 21 can be used as a gripping structure for the operator to hold when dumping the ash in the ash pan 4, avoiding directly dumping the ash in the ash pan 4 by holding the ash pan 4 and causing burns. A support ring 121 is formed by turning the inner edge from the lower end of the outer cavity structure 12, and the combustion structure 1 is supported on the upper side of the support plate 31 by the support ring 121, which provides better stability for the installation of the combustion structure 1.

[0044] In some specific embodiments, the ash pan 4 is connected to the support plate 31 through the first connection structure 6, and the adjustment plate 32 is rotatably connected to the support plate 31 through the rotation shaft 8 arranged along the axis of the support plate 31. In this embodiment, the support plate 31 is provided with a first connection hole 312 along its axis, and the adjustment plate 32 is provided with a second connection hole 322 along its axis. The support plate 31 and the adjustment plate 32 are rotatably connected through bolts inserted into the first connection hole 312 and the second connection hole 322 and nuts matched and connected to the bolts. The connection shaft part of the bolt forms the rotation shaft 8, which has a simple structure and is easy to install and disassemble.

[0045] In some specific embodiments, the air guide channel 30 includes an air inlet hole 311 penetrating the support plate 31, and an adjustment hole 321 penetrating the adjustment plate 32 corresponding to the air inlet hole 311. The adjustment plate 32 can rotate between a fully open position and a closed position relative to the support plate 31. In the fully open position, the adjustment hole 321 and the air inlet hole 311 are arranged opposite to each other and are connected to each other. At this time, the air volume entering the combustion structure 1 is the largest. In the closed position, the adjustment hole 321 and the air inlet hole 311 are arranged in a staggered manner, and the adjustment hole 321 is blocked by the support plate 31, and the air inlet hole 311 is blocked by the adjustment plate 32. At this time, air cannot enter the combustion structure 1 through the air guide structure 3. By rotating the adjustment plate 32 relative to the support plate 31 between the fully open position and the closed position, the area of ​​the adjustment hole 321 and the air inlet hole 311 connected to each other is adjusted, thereby adjusting the air volume.

[0046] like Figure 1 , Figure 2 , Fig. 9 As shown, in some specific embodiments, an operating portion 323 is extended outward from one side of the adjustment plate 32 for the operator to rotate the adjustment plate 32 relative to the support plate 31, and a guide channel 22 is provided on the wall of the support structure 2. The operating portion 323 passes through the guide channel 22 and extends out of the outside of the support structure 2, and can move along the guide channel 22 to drive the adjustment plate 32 to rotate relative to the support plate 31 between a fully open position and a closed position.
