[0026] The utility model provides a fire basin 100.
[0027] Reference Figures 1 to 4The embodiment of the fire basin 100 includes a basin body 1, a perforated plate 2 and an air guide ring 3. The basin body 1 is enclosed to form a combustion chamber. The bottom plate of the basin body 1 is provided with first air inlet holes 11 arranged in a circular array. The perforated plate 2 is arranged at the bottom of the combustion chamber and covers the combustion chamber. An air guide gap 13 is formed between the perforated plate 2 and the bottom plate of the basin body 1. The air guide ring 3 is clamped in the air guide gap 13 and divides the air guide gap 13 into an inner circle gap 131 and an outer circle gap 132. The air guide ring 3 is hollow to form an air guide channel 34. The lower end of the air guide ring 3 is open and covers the first air inlet hole 11. The side wall of the air guide ring 3 is provided with an air outlet. After the outdoor wind enters the air guide channel 34 from the first air inlet hole 11, it enters the inner circle gap 131 and / or the outer circle gap 132 from the air outlet, and then flows upward through the perforated plate 2.
[0028] The fire basin needs to have holes at the bottom of the basin to allow air to enter and help the combustion of the combustibles. However, in order to avoid the ground temperature being too high when the combustibles are burning, the number of holes at the bottom of the basin should not be too many. Since the number of holes at the bottom of the basin is limited, there will be a problem of insufficient air supply, which will easily produce incomplete combustion such as black smoke and carbon monoxide. For this reason, the fire basin 100 of the utility model is equipped with a perforated plate 2 and an air guide ring 3 at the bottom of the combustion chamber.
[0029] Specifically, the basin body 1 includes an integrally formed bottom plate and side plates, which enclose a combustion chamber, the center of the bottom plate is concave, the diameter of the orifice plate 2 is consistent with the inner diameter of the side plate, the orifice plate 2 is arranged at the bottom of the combustion chamber and covers the combustion chamber, and ensures that an air guide gap 13 is formed between the orifice plate 2 and the bottom plate. A plurality of holes arranged in an array are provided on the plate surface of the orifice plate 2 to connect the upper chamber of the orifice plate 2 and the air guide gap 13. The air guide ring 3 is clamped in the air guide gap 13, and the air guide ring 3 includes an inner ring piece 31, an outer ring piece 32 and a top ring piece 33. The inner ring piece 31 is arranged around the inner circle of the first air inlet hole 11, and the outer ring piece 32 is arranged around the outer circle of the first air inlet hole 11. The top ring piece 33 is arranged on the top surfaces of the inner ring piece 31 and the outer ring piece 32 to connect the inner ring piece 31 and the outer ring piece 32. The inner ring piece 31, the outer ring piece 32 and the top ring piece 33 enclose an air guide channel 34. The enclosed area of the inner ring piece 31 is the inner circle gap 131, and the outer peripheral area of the outer ring piece 32 is the outer circle gap 132. The top ring piece 33 is in contact with and fits with the orifice plate 2.
[0030] Thus, the particulate combustion material (such as carbon particles, firewood, etc.) is placed on the orifice plate 2 and ignited, and the outdoor wind enters the air guide channel 34 from the first air inlet 11, enters the inner ring gap 131 and / or the outer ring gap 132 from the air outlet hole on the side wall of the air guide ring 3, and then flows upward through the holes of the orifice plate 2, thereby assisting the combustion of the combustion material. In summary, the wind blows toward the combustion material from the holes arranged in an array on the orifice plate 2, increasing the wind receiving area of the combustion material, thereby promoting the full combustion of the combustion material.
[0031] In one embodiment, a first air outlet 311 is provided on the peripheral side wall of the inner ring plate 31 to connect the air guide channel 34 and the inner ring gap 131. After the outdoor wind enters the air guide channel 34 from the first air inlet 11, it enters the inner ring gap 131 from the first air outlet 311, and then flows upward through the holes of the orifice plate 2, thereby assisting the combustion of the combustible material.
[0032] In one embodiment, a second air outlet 321 is provided on the peripheral side wall of the outer ring sheet 32 to connect the air guide channel 34 and the outer ring gap 132. After the outdoor wind enters the air guide channel 34 from the first air inlet 11, it enters the outer ring gap 132 from the second air outlet 321, and then flows upward through the holes of the orifice plate 2, thereby assisting the combustion of the combustible material.
[0033] In one embodiment, the circumferential side wall of the inner ring sheet 31 is provided with a first air outlet 311, and the circumferential side wall of the outer ring sheet 32 is provided with a second air outlet 321. After the outdoor wind enters the air guide channel 34 from the first air inlet 11, it enters the inner ring gap 131 from the first air outlet 311, and enters the outer ring gap 132 from the second air outlet 321. The air volume in the inner ring gap 131 and the outer ring gap 132 flows upward through the holes of the orifice plate 2, thereby assisting the combustion of the combustible. At this time, the wind-receiving area of the combustible is larger, and the combustion efficiency is greater. Among them, the number of the first air outlet holes 311 and the second air outlet holes 321 are both multiple, and the multiple first air outlet holes 311 are arranged circumferentially at intervals along the circumferential side wall of the inner ring sheet 31, and the multiple second air outlet holes 321 are arranged circumferentially at intervals along the circumferential side wall of the outer ring sheet 32, thereby ensuring that the inner ring sheet 31 and the outer ring sheet 32 have a higher porosity and ensuring that the wind in the air guide channel 34 can quickly flow into the inner ring gap 131 and the outer ring gap 132.
[0034] Among them, the aperture of the first air inlet hole 11 on the bottom plate of the basin body 1 is larger than the aperture of the first air outlet hole 311 and the second air outlet hole 321. The aperture of the first air outlet hole 311 and the aperture of the second air outlet hole 321 may be consistent or inconsistent. The total area of the first air inlet hole 11 is larger than the total area of the first air outlet hole 311 or the total area of the second air outlet hole 321, so that the air intake efficiency of the air guide channel 34 is greater than the air outlet efficiency, which accelerates the outflow speed of the wind in the air guide channel 34 and further improves the combustion efficiency.
[0035] Reference Figure 4 The lower end of the inner ring piece 31 is bent inward to provide a first connecting piece 312, and the lower end of the outer ring piece 32 is bent outward to provide a second connecting piece 322. The bottom surfaces of the first connecting piece 312 and the second connecting piece 322 are flush with each other, and the first connecting piece 312 and the second connecting piece 322 are both fitted and fixed to the bottom plate of the basin body 1. If the material of the air guide ring 3 is metal material, such as steel plate, aluminum plate, copper plate, etc., the first connecting piece 312 and the second connecting piece 322 are both welded and fixed to the bottom plate of the basin body 1, thereby achieving the fixation of the air guide ring 3 and the basin body 1.
[0036] Reference Figures 1 to 3 The embodiment of the fire basin 100 further includes legs 4, which are arranged at the bottom of the basin body 1 and are used to stand up the basin body 1 to ensure that there is a certain space between the basin body 1 and the ground for ventilation. The legs 4 can be provided with three, four or more legs, and the legs 4 and the basin body 1 are detachably connected, such as threaded connection, and the legs 4 can be removed when the fire basin 100 is transported, thereby saving the occupied space.
[0037] It should be noted that the fire basin 100 of the utility model can be a shallow fire basin or a deep fire basin. The so-called shallow fire basin means that the depth of the basin body 1 is not greater than the radius of the basin body 1, and the so-called deep fire basin means that the depth of the basin body 1 is greater than the radius of the basin body 1. If the fire basin 100 is shallow, the combustion is greatly affected by the outdoor wind. When it is a deep fire basin, the side panel of the basin body 1 is provided with second air inlet holes 12 arranged in a circular array. The shape of the second air inlet holes 12 can be circular, triangular or diamond-shaped. And the second air inlet holes 12 can be arranged at the upper end of the side panel of the basin body 1, so as to ensure the air intake while weakening the influence of the outdoor wind. At this time, the outdoor wind can blow to the combustion object from the first air inlet hole 11, and can also blow to the combustion object from the second air inlet hole 12, so as to ensure sufficient air supply to the combustion chamber and reduce black smoke. In addition, if Figure 3 As shown, the wind at the bottom of the basin body 1 blows upward toward the flame, and the wind at the side of the basin body 1 blows horizontally toward the flame. The flame forms a rotating and beautiful flame vortex under the action of air convection, and the jumping flame has a certain ornamental value.
