Technical Field
[0001] The utility model relates to the field of stoves, in particular to a pot support and a burner comprising the same. Background Art
[0002] In the prior art, the burner includes an inner ring fire cover and an outer ring fire cover. When the burner burns, the primary air-gas premix passes through the fire distributor and then sprays out from the fire hole of the fire cover to achieve combustion. At the same time, in order to ensure the stable combustion of the inner ring fire cover, secondary air needs to be added.
[0003] The burner in the prior art usually realizes secondary air replenishment of the inner ring fire cover by means of a secondary air inlet opened on the outer ring fire cover. The secondary air replenishment of the outer ring fire cover comes from the root of the fire hole of the outer ring fire cover and the surrounding air. However, the secondary air replenishment is often difficult to control effectively, so that the burner often has problems such as insufficient secondary air replenishment leading to unstable combustion state and excessive secondary air replenishment leading to reduced combustion efficiency, which affects the normal use of the burner. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the defect that the secondary air supply of the burner in the prior art is often difficult to effectively control, so that the burner often has the problem of insufficient secondary air supply resulting in unstable combustion state and excessive secondary air supply resulting in reduced combustion efficiency, which affects the normal use of the burner. A pot bracket and a burner containing the same are provided.
[0005] The utility model solves the above technical problems through the following technical solutions:
[0006] A pot support is arranged on an outer ring fire cover of a burner, and its characteristic is that the pot support includes an energy focusing ring belt, the lower edge of the energy focusing ring belt is higher than the secondary air inlet of the outer ring fire cover, and the vertical distance between the lower edge of the energy focusing ring belt and the secondary air inlet is a preset air intake distance.
[0007] In this solution, the above structure is adopted, the pot support is set on the burner, and the energy-gathering ring belt of the pot support is just above the secondary air inlet, so that it will not block the secondary air inlet, ensuring sufficient supplementation of secondary air to make combustion more complete. At the same time, the vertical distance between the energy-gathering ring belt and the secondary air inlet is controlled at a preset air intake distance, and the air intake area of the secondary air is controlled by the energy-gathering ring belt to avoid excessive secondary air supplementation affecting the combustion efficiency.
[0008] Preferably, the preset air intake distance is 4.1 mm.
[0009] In this solution, the above structure is adopted, and when the preset air intake distance is set to 4.1 mm, the flame combustion state is optimal, and the flame is clear without false flames.
[0010] Preferably, the upper edge of the energy-gathering ring belt is lower than the fire outlet path and the high-temperature smoke path of the fire holes of the outer ring fire cover.
[0011] In this solution, the above structure is adopted, and the upper edge of the energy-gathering ring belt is lower than the fire outlet path and high-temperature flue gas path of the fire holes of the outer ring fire cover, which does not interfere with the smoke discharge and burner ignition, thereby ensuring the efficiency and stability of normal combustion of the burner.
[0012] Preferably, the projection of the energy focusing ring belt in the horizontal direction covers the projection of the fire outlet of the fire hole of the outer ring fire cover in the horizontal direction so that the height of the fire hole is located between the upper edge and the lower edge of the energy focusing ring belt.

[0014] Preferably, the energy focusing ring belt is arranged perpendicular to the table surface of the burner.
[0015] In this solution, the above-mentioned structure is adopted, and the energy focusing ring belt is arranged perpendicular to the table top. Compared with the inclined setting of the energy focusing ring belt, the vertically set energy focusing ring belt has better control over the air intake of the secondary air inlet. At the same time, the vertically set energy focusing ring belt is farther away from the fire hole, and has less interference with the fire outlet path.
[0016] Preferably, the pot support further comprises a plurality of corner pieces, the outer sides of the plurality of corner pieces are provided with fixing grooves, and the energy gathering ring belt is clamped on the corner pieces.
[0017] In this solution, the above structure is adopted, and the energy-gathering ring belt is clamped in the groove on the outer side of the fixed angle piece, which has a simple structure and is easy to assemble.

[0019] In the present solution, the above structure is adopted, and the corner pieces are arranged between a plurality of secondary air inlets to prevent the corner pieces from blocking the secondary air inlets and hindering air intake, thereby ensuring air replenishment.
[0020] Preferably, the right-angle end of the energy-gathering ring belt is arranged corresponding to the secondary air inlet of the outer ring fire cover.
[0021] In the present scheme, the above-mentioned structure is adopted, and the energy focusing ring belt is square, so that its inner wall surface is flat, which is convenient for assembly with the corner piece. The right-angle end of the energy focusing ring belt is arranged opposite to the secondary air inlet, which can increase the distance between the energy focusing ring belt and the secondary air inlet, and limit the air conduction to the secondary air inlet through the energy focusing ring belt from a farther distance, so as to achieve better control effect.
[0022] A burner comprises an outer ring fire cover, and is characterized in that it also comprises a pot support as described in any one of the above items.
[0023] In this solution, the above structure is adopted, and the energy-gathering ring belt of the pot support of the burner is located just above the secondary air inlet, so that it will not block the secondary air inlet, ensuring sufficient supplementation of secondary air to make combustion more complete. At the same time, the vertical distance between the energy-gathering ring belt and the secondary air inlet is controlled at a preset air intake distance, and the air intake area of the secondary air is controlled by the energy-gathering ring belt to avoid excessive secondary air supplementation affecting the combustion efficiency.
[0024] Preferably, the fire holes of the outer ring fire cover are inclined upward from inside to outside so that the fire outlet path and the high-temperature smoke path are higher than the upper edge of the energy-gathering ring belt of the pot support.
[0025] In this scheme, the above structure is adopted, and the height difference between the pot support and the fire cover is matched with the inclination angle design of the main fire hole to ensure that the contact area between the inner cone height of the flame and the bottom of the pot is at a reasonable value. The design value of the smoke exhaust port height is 16.5. The horizontal direction of the ignition positions of all main fire holes are within the range of the ring belt, and the ignition path and the high-temperature smoke path are higher than the ring belt, which can achieve energy gathering without affecting the smoke.

[0047] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0048] like Figure 1 As shown, this embodiment provides a burner, which includes two burners 1 arranged on a table 101, and each burner 1 includes an inner ring fire cover 11 and an outer ring fire cover 12. Among them, a plurality of secondary air inlets 121 are opened at the bottom of the peripheral side of the outer ring fire cover 12, which pass from the outer side of the outer ring fire cover 12 to the inner side of the outer ring fire cover 12. Each burner 1 is also provided with a corresponding overflow pan 3 and a pot support 2.
[0049] like Figure 1 , Figure 2 As shown, the pot support 2 of this embodiment is arranged on the outer ring fire cover 12 of the burner, specifically, it is arranged on the outside of the outer ring fire cover 12, and the pot support 2 includes an energy focusing ring belt 21, the lower edge of the energy focusing ring belt 21 is higher than the secondary air inlet 121 of the outer ring fire cover 12 and the vertical distance between the lower edge of the energy focusing ring belt 21 and the secondary air inlet 121 is a preset air intake distance d.
[0050] Specifically, the energy-gathering belt 21 is a closed ring, which is arranged around the outer ring fire cover 12, extends a certain distance in the vertical direction, and has a certain height gap from the table 101, thereby dividing the outer side of the outer ring fire cover 12 into three action areas: a smoke exhaust area, an energy-gathering area, and a secondary air replenishment area. Among them, the smoke exhaust area is the space above the upper edge of the energy-gathering belt 21 that is not blocked by the energy-gathering belt 21, for the smoke to be discharged when the outer ring fire cover 12 burns; the energy-gathering area is the space that is just blocked by the energy-gathering belt 21 in the horizontal direction, which can block heat loss; the secondary air replenishment area is the space formed by the gap between the energy-gathering belt 21 and the table 101, and air can enter the bottom of the outer ring fire cover 12 from the gap below the energy-gathering belt 21, and circulate through the secondary air inlet 121 of the outer ring fire cover 12 to achieve secondary air replenishment.
[0051] In this embodiment, the pot support 2 is arranged on the burner, and the energy-gathering ring belt 21 of the pot support 2 is just located above the secondary air inlet 121, so that it will not block the secondary air inlet 121, ensuring sufficient supplement of secondary air to make combustion more complete. At the same time, the vertical distance between the energy-gathering ring belt 21 and the secondary air inlet 121 is controlled at a preset air intake distance d, and the air intake area of the secondary air is controlled by using the energy-gathering ring belt 21, so as to avoid excessive secondary air supplement affecting the combustion efficiency.
[0052] like Figure 4 , Figure 5 In this embodiment, in the secondary air replenishment area, the lower edge of the energy focusing ring belt 21 is higher than the secondary air inlet 121, and the preset air intake distance d from the secondary air inlet 121 is 4.1 mm. When the preset air intake distance d is set to 4.1 mm, the flame combustion state is optimal, and the flame is clear without false flames.
[0053] In other embodiments, it may be set to a smaller or larger setting, but it may also cause a decrease in the combustion state due to insufficient or excessive air intake.
[0054] like Figure 6 As shown, the upper edge of the energy-gathering ring belt 21 is lower than the fire outlet path s and the high-temperature smoke path of the fire hole of the outer ring fire cover 12. Specifically, Figure 6 It is a cross-sectional view, from which it can be seen that the extension line of the fire hole is located above the energy focusing ring belt 21, so it can be known that the fire path s and the high-temperature smoke path will not be blocked by the energy focusing ring belt 21. In this embodiment, the upper edge of the energy focusing ring belt 21 is lower than the fire path s and the high-temperature smoke path of the fire hole of the outer ring fire cover 12, and does not interfere with the smoke discharge and the burner ignition, ensuring the efficiency and stability of the normal combustion of the burner.
[0055] like Figure 6As shown, the horizontal projection of the energy-gathering ring belt 21 covers the horizontal projection of the fire outlet of the fire hole of the outer ring fire cover 12 so that the height of the fire hole is located between the upper edge and the lower edge of the energy-gathering ring belt 21. Specifically, Figure 6 In the figure, the dotted line is the horizontal line of the fire hole height h, which is known to be between the energy focusing ring belts 21. In this embodiment, the fire hole ignition position is within the range of the energy focusing ring belt 21 in the horizontal direction, which can achieve energy gathering without affecting the smoke.
[0056] like Figure 1 As shown, the energy focusing ring belt 21 is arranged perpendicularly to the table 101 of the burner. In this embodiment, the energy focusing ring belt 21 is arranged perpendicularly to the table 101. Compared with the inclined arrangement of the energy focusing ring belt 21, the vertically arranged energy focusing ring belt 21 has better air intake control for the secondary air inlet 121. At the same time, the vertically arranged energy focusing ring belt 21 is farther from the fire hole, and has less interference with the fire outlet path s.
[0057] In other embodiments, although the energy focusing ring belt 21 can also be set to be an inclined disk, it will cause its air inlet to be conical, and the control effect is not as good as the vertical setting.
[0058] like Figure 1 As shown, the pot support 2 also includes a plurality of corner pieces 22, and a fixing groove is provided on the outer side of the plurality of corner pieces 22, and the energy-gathering ring belt 21 is clamped on the corner piece 22. In this embodiment, the energy-gathering ring belt 21 is clamped in the groove on the outer side of the fixing corner piece 22, and the structure is simple and easy to assemble.
[0059] In addition, if Figure 4 As shown, a plurality of corner pieces 22 are arranged between a plurality of secondary air inlets 121 of the outer ring fire cover 12. In this embodiment, the corner pieces 22 are arranged between a plurality of secondary air inlets 121 to prevent the corner pieces 22 from blocking the secondary air inlets 121 and hindering air intake, thereby ensuring air replenishment.
[0060] In this embodiment, the corner pieces 22 are all fixed on the edge of the overflow tray 3. Specifically, Figure 2 , Figure 3 As shown, the overflow tray 3 has a protrusion, and the protrusion and the stove head 1 together define a concave portion of the overflow tray for accommodating liquid. The inward edge of the protrusion has a notch, and the end of the corner piece 22 is fixed in the notch.
[0061] like Figure 3 As shown, the right-angle end of the energy-gathering belt 21 is arranged corresponding to the secondary air inlet 121 of the outer ring fire cover 12. In this embodiment, the energy-gathering belt 21 is square, so that its inner wall surface is flat, which is convenient for assembly with the corner piece 22. The right-angle end of the energy-gathering belt 21 is arranged directly opposite the secondary air inlet 121, which can increase the distance between the energy-gathering belt 21 and the secondary air inlet 121, and limit the air conduction to the secondary air inlet 121 from a farther distance through the energy-gathering belt 21, so as to achieve a better control effect.
[0062] In other embodiments, the energy focusing ring belt 21 may also be arranged in a ring shape, but this will make the distance between the energy focusing ring belt 21 and the secondary air inlet 121 close, thereby reducing its air inlet control effect.
[0063] like Figure 6 As shown, the fire holes of the outer ring fire cover 12 are tilted upward from the inside to the outside so that the fire path s and the high-temperature smoke path are higher than the upper edge of the energy-gathering ring belt 21 of the pot support 2. In this embodiment, the height difference of the pot support 2 and the fire cover is designed in accordance with the inclination angle of the main fire hole to ensure that the height of the inner cone of the flame and the contact area of the pot bottom are at a reasonable value, and the height design value of the smoke exhaust port is 16.5. The horizontal direction of the fire positions of all main fire holes are within the range of the ring belt, and the fire path s and the high-temperature smoke path are higher than the ring belt, which can achieve energy gathering without affecting the smoke. The ring belt separates the air inlet channel and the smoke exhaust channel to ensure that there is no interference between the two to maintain stable combustion.
