For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0032] Combine the following Figures 1 to 5 , describing an embodiment of the utility model.
[0033] According to an embodiment of the utility model, a burner of a gas stove is provided, such as Figures 1 to 5 As shown, it includes an annular base 1, an annular cover plate 4 arranged on the base 1, and an annular fire hole plate 3 arranged between the cover plate 4 and the base 1. The fire hole plate 3 is installed on the base outer ring side wall 13 of the base 1. The cover plate 4 is installed on the base inner ring side wall 12 of the base 1. A mixing chamber A is formed between the cover plate 4 and the base. A plurality of flame stabilizing holes 31 are arranged at intervals along the circumferential direction on the fire hole plate 3, and the flame stabilizing holes 31 are located on the outer side of the cover plate 4. A main fire groove C is formed between the outer ring side wall 42 of the cover plate and the inner ring side wall 32 of the fire hole plate, and the fire direction of the flame stabilizing hole 31 and the fire direction of the main fire groove C have an angle α, and the angle of the angle is 10 degrees to 60 degrees.
[0034] The burner of the gas stove provided by the utility model is provided with a fire hole plate 3. Compared with the prior art technologies of directly drilling holes in the outer wall of the base, the flame stabilizing hole 31 opened on the fire hole plate 3 can be straighter, so that the flame coming out of the flame stabilizing hole 31 can better offset the flame coming out of the main fire groove C. The fire outlet direction of the flame stabilizing hole 31 intersects with the fire outlet direction of the main fire groove C. The flame coming out of the flame stabilizing hole 31 will offset the flame coming out of the main fire groove C. The flame stabilizing hole 31 just burns the root of the flame coming out of the main fire groove C, which can reduce the risk of flame separation and thus improve the combustion stability.
[0035] In one embodiment, if Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the burner of the gas stove also includes an annular gas distribution plate 2. The gas distribution plate 2 divides the mixing chamber A into a first air chamber A1 and a second air chamber A2. An air inlet 11 is provided on the bottom wall 14 of the base, and the air inlet 11 is connected to the air inlet ring 5. The gas distribution plate 2 is placed in the base 1, so that the inner ring side wall 23 of the gas distribution plate fits with the inner ring side wall 12 of the base, and the outer ring side wall 24 of the gas distribution plate fits with the outer ring side wall 13 of the base, and the aforementioned first air chamber A1 in an annular shape is formed between the base 1 and the gas distribution plate 2. The first air chamber A1 is connected to the air inlet 11. A plurality of air outlet holes 22 connected to the first air chamber A1 are provided on the top wall of the gas distribution plate 2. The fire hole plate 3 is located on the outer side of the cover plate 4, and the bottom wall 34 of the fire hole plate is flush with the bottom wall 45 of the cover plate. The outer ring side wall 33 of the fire hole plate is interference fit with the outer ring side wall 13 of the base, and the top of the outer ring side wall 33 of the fire hole plate protrudes radially outward to form a boss 331, and the boss 331 abuts against the top of the outer ring side wall 13 of the base. Of course, the fire hole plate 3 can also be connected to the base 1 in other forms such as threads. The inner ring side wall 41 of the cover plate is connected to the inner ring side wall 12 of the base. The bottom wall 45 of the cover plate and the bottom wall 34 of the fire hole plate together form a second air cavity A2 with the gas distribution plate 2. The aforementioned flame stabilizing hole 31 is connected to the second air cavity A2, and is connected to the first air cavity A1 through the air outlet hole 22. A plurality of auxiliary fire grooves 44 are provided on the top wall 43 of the cover plate. As Figure 1 and Figure 3 As shown, a plurality of auxiliary fire grooves 44 are radially arranged around the inner ring side wall 41 of the cover plate. The auxiliary fire grooves 44 are connected to the second air cavity A2.
[0036] In one embodiment, the flame stabilizing hole 31 is vertically arranged to facilitate the processing of the flame stabilizing hole 31 , and the main fire groove C is inclined from the inside to the outside from bottom to top.
[0037] For the main fire groove C, in one embodiment, the outer ring side wall 42 of the cover plate is set to an inverted conical surface corresponding to the main fire groove C, and the inner ring side wall 32 of the fire hole plate is also an inverted conical surface. The inner ring side wall 32 of the fire hole plate and the outer ring side wall 42 of the cover plate form the main fire groove C and are parallel to each other. Compared with the design in which the inner ring side wall 32 of the fire hole plate and the outer ring side wall 42 of the cover plate are set at an angle, this design is more conducive to the flame flowing out of the main fire groove C and the flame flowing out of the flame stabilizing hole 31 to collide with each other, thereby reducing the risk of flame separation and further improving combustion stability.
[0038] In one embodiment, the width value of the main fire groove C (the width direction is perpendicular to the direction of the outer ring side wall of the cover plate 4), the diameter value of the flame stabilizing hole 31, and the width value of the auxiliary fire groove 44 (the width direction is along the circumferential direction of the cover plate 4) are all much larger than the width value of the air outlet 22 (the width direction is along the height direction of the air distribution plate 2). In this way, the risk of flashback can be reduced.
[0039] In one embodiment, the inner ring side wall 41 of the cover plate is threadedly connected to the inner ring side wall 12 of the base. In this way, the width of the main fire groove C can be adjusted by adjusting the threaded connection depth between the cover plate 4 and the base 1, so that the burner of the gas stove can adapt to the stable combustion requirements of different gas sources. Specifically, the mixed gas flow speed of artificial gas is fast, and the size of the main fire groove C required for stable combustion is small to prevent backfire; the mixed gas flow speed of natural gas is slow, and the size of the main fire groove C required for stable combustion is large to prevent flameout.
[0040] In one embodiment, in order to facilitate the adjustment of the threaded connection depth between the cover plate 4 and the base 1, an operating portion for adjusting the connection depth between the cover plate 4 and the base 1 is provided on the inner ring side wall 41 of the cover plate. Specifically, a convex block is formed on the inner ring side wall 41 of the cover plate to protrude in the axial direction of the cover plate 4, and a notch 411 is provided on the convex block. The notch 411 serves as an operating portion to provide a plug-in space for tools such as a plug-in rod, and the cover plate can be forced to rotate by hitting the plug-in rod with a hammer.
[0041] In one embodiment, if Figure 1 and Figure 2 As shown, a gas distribution plate 2 is also provided, and the gas distribution plate 2 is provided between the fire hole plate 3 and the base 1, and the top wall 25 of the gas distribution plate is an inverted conical surface. A plurality of convex ribs 21 are provided on the top wall 25 of the gas distribution plate, and the plurality of convex ribs 21 are radially arranged around the axis and spaced apart, and the ridge direction of the convex ribs 21 is away from the base 1, and the plurality of convex ribs 21 are respectively provided with air outlet holes 22 on the same side, so that the mixed gas of the gas source and the air will form a swirl when flowing out of the air outlet hole 22, thereby making the gas source and the air mixed more evenly, and finally improving the completeness of combustion and reducing the generation of harmful substances such as smoke.
[0042] In one embodiment, the distribution density of the ribs 21 in the area near the air inlet 11 is lower than that in the area far from the air inlet 11. In this way, the pressure in the second air cavity A2 between the cover plate 4 and the air distribution plate 2 can be more uniform, thereby improving the uniformity of the flame.
[0043] The following describes the working process of the gas stove burner:
[0044] The gas source enters the first air cavity A1 from the air intake ring 5. Since the distribution density of the ribs 21 in the area near the air inlet 11 (the gas source concentration in this area is high) is less than the distribution density in the area far away from the air inlet 11 (the gas source concentration in this area is low), the concentration of the gas source flowing out of the gas distribution plate 2 can be more evenly distributed, and the pressure in the second air cavity A2 between the cover plate 4 and the gas distribution plate 2 can be more even. Since the air outlet holes 22 are arranged on the same side of the ribs 21, a vortex will be formed when the mixed gas of the gas source and the air flows out of the air outlet holes 22, and the gas source and the air can be mixed more evenly to form a mixed gas. The mixed gas flows out from the main fire groove C, the flame stabilizing hole 31, and the auxiliary fire groove 44 for combustion. In addition, since the ignition direction of the flame stabilizing hole 31 intersects with the ignition direction of the main fire groove C, the flame coming out of the flame stabilizing hole 31 will collide with the flame coming out of the main fire groove C, just burning the root of the flame coming out of the main fire groove C, which can reduce the risk of flame separation and improve the combustion stability.
[0045] When the gas source entering the gas stove changes, insert a rod-like tool into the notch 411 and hit the rod with a hammer to force the cover 4 to rotate to adjust the threaded connection depth between the cover 4 and the base 1, thereby changing the width value of the main fire groove C to adapt to the requirements of different gas sources for the width value of the main fire groove C. Specifically, the mixed gas flow speed of artificial gas is fast, and the size of the main fire groove C required for stable combustion is small to prevent backfire; the mixed gas flow speed of natural gas is slow, and the size of the main fire groove C required for stable combustion is large to prevent flameout.
[0046] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The specific contents of the above specific implementations only express several implementations of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
