Referring to fig. 1-3, the burner 10 includes a burner head 12, an air supply 14, and a burner cap portion 16. The burner 12 defines a first gas chamber 122. The air supply part 14 is arranged at the periphery of the burner 12, the air supply part 14 is provided with an air supply cavity 142, the bottom of the air supply part 14 is provided with an air inlet 144, the air inlet 144 is communicated with the air supply cavity 142, an air flow equalizing plate 145 is arranged above the air inlet 144, and the top of the air supply part 14 is provided with an air outlet 146 communicated with the air supply cavity 142. The burner cover 16 is disposed on the burner 12 and the air supply portion 14, the burner cover 16 is opened with fire holes 1642 communicating with the first gas chamber 122, the burner 10 is formed with a secondary air intake passage 18 penetrating the burner cover 16, and the secondary air intake passage 18 communicates with the air outlet 146 and the fire holes 1642.
According to the burner 10 provided by the embodiment of the invention, air enters the air supply cavity 142 from the air inlet 144 at the bottom of the air supply part 14 upwards, collides with the air flow equalizing plate 145, changes the movement direction and flows around the air supply cavity 142 in a dispersing manner, so that the air is uniformly distributed in the air supply cavity 142, then flows to the secondary air inlet channel 18 from the air outlet 146 and reaches the fire hole 1642, so that the secondary air can be fully supplemented by the gas at the fire hole 1642, the combustion is more sufficient, the discharge amount of harmful gas is reduced, the burner is more environment-friendly and healthy, and the heat efficiency is higher.
Specifically, in the embodiment of the present invention, there is a gap 15 between the edge of the air outlet 146 and the bottom of the fire lid portion 16, and the air outlet 146 is in open connection with the secondary air intake channel 18, that is, more secondary air can be sucked from the gap 15 and delivered to the secondary air intake channel 18. It will be appreciated that when the burner 10 is in operation, combustion gases are combusted at the outlet of the fire holes 1642, and the pressure above the fire cap portion 16 is lower than the pressure below the fire cap portion 16, so that air in the air supply chamber 142 flows from bottom to top through the secondary air inlet passage 18 to the fire holes 1642 by the pressure difference. In addition to air entering the fire hole 1642 from the air inlet 144, air may enter the secondary air inlet channel 18 from the space 15 between the edge of the air outlet 146 and the bottom of the fire cover 16 and flow to the fire hole 1642. Therefore, the secondary air can be supplemented more fully by the gas at the fire hole 1642, and the combustion is more sufficient.
In some embodiments, the air supply 14 is formed with a plurality of air inlets 144, and the plurality of air inlets 144 are evenly distributed at the bottom of the air supply 14.
Thus, the air inlets 144 make the air more uniformly distributed in the air supply cavity 142, so that the gas at the fire holes 1642 can fully supplement the air, and the combustion is more sufficient.
It is understood that the number of the air inlets 144 may be one, or two or more.
Specifically, an air flow equalizing plate 145 is disposed above each of the air inlets 144. Thus, the air entering the air supply chamber 142 from the air inlet 144 collides with the air flow equalizing plate 145, changes the moving direction, and disperses around the air supply chamber 142 to be uniformly distributed in the air supply chamber 142.
In some embodiments, a fan (not shown) is coupled to the air inlet 144.
In this manner, the fan can increase the flow rate of the air, thereby enabling the secondary air to be sufficiently replenished by the fuel gas at the fire holes 1642.
Specifically, the blower may be a direct flow blower that blows air toward the air inlet 144 to help promote the flow rate of the air within the secondary air intake passage 18. Therefore, the phenomenon that waste gas discharged by combustion is easy to directly flow back to cause the air quality in the air supply cavity 142 to be poor is avoided.
In some embodiments, the side wall of the burner 12 is provided with a connecting duct 124, and the connecting duct 124 is connected to a blower and air inlet 144.
Therefore, more air blown out from the fan is blown to the air inlet 144, the utilization efficiency of the air blown out from the fan is improved, the air flow entering the air supply cavity 142 is effectively increased, so that the gas at the fire hole 1642 can fully supplement secondary air, and meanwhile, the unstable state of the air blown out from the fan on the combustion at the fire hole 1642 can be prevented.
Specifically, when the air supply part 14 is formed with a plurality of air inlets 144, the plurality of air inlets 144 may be communicated with the same fan, each air inlet 144 may be connected with a fan, a plurality of air inlets 144 in the plurality of air inlets 144 may be connected with a fan together, a plurality of air inlets 144 are connected with a fan, and the like.
In the present embodiment, the connection pipe 124 has a cylindrical shape, and one end of the connection pipe 124 extends into the air inlet 144. This can introduce the outside air into the air supply chamber 142 to the maximum.
In some embodiments, the air equalizer 145 has a plurality of spaced apart mesh openings 1452, and the size of the mesh openings 1452 is smaller than the size of the air inlet 144.
Thus, a portion of the air can flow from the openings 1452 to the top of the air balance plate 145, and another portion of the air can be guided to other positions of the air supply chamber 142 from the portion of the air balance plate 145 between the openings 1452.
It will be appreciated that air enters the air supply chamber 142 from the air inlet 144 at the bottom of the air supply 14, and a portion of the air collides with the air equalizer 145 to change its direction of motion to be distributed around the air supply chamber 142, and a portion of the air is also required above the air equalizer 145, so that the air equalizer 145 is perforated with holes 1452 to allow another portion of the air to reach above the air equalizer 145, thereby more uniformly distributing the air in the air supply chamber 142.
In the embodiment of the present invention, the air flow equalizing plate 145 has a flat plate shape and is perpendicular to the central axis X of the connecting pipe 124.
In some embodiments, the number of the secondary air inlet passages 18 is multiple, the multiple secondary air inlet passages 18 are arranged at intervals along the circumferential direction of the burner 12, the air outlet 146 is annular, and the air outlet 146 covers the multiple secondary air inlet passages 18.
Thus, the air flowing out of the air outlet 146 is divided into a plurality of strands to enter different secondary air inlet channels 18, so that the air can be more uniformly supplemented to the fire holes 1642, and the combustion is more stable.
The air outlet 146 covers the plurality of secondary air inlet channels 18, and it can be understood that orthographic projections of the plurality of secondary air inlet channels 18 on the air outlet are all located in the air outlet 146, as shown in fig. 4.
Referring to fig. 4, in some embodiments, the burner cap portion 16 is formed with a hub structure 162 expanding outward from the first gas chamber 122, the hub structure 162 includes a plurality of support arms 164 arranged at intervals, a secondary air intake channel 18 is formed between two adjacent support arms 164, and a top surface of each support arm 164 is provided with a burner hole 1642.
Therefore, the hub structure 162 enables the fire holes 1642 to be supplemented with secondary air in an all-around manner, so that the heat efficiency is greatly improved, meanwhile, the fuel gas can be fully combusted, the discharge amount of pollutants such as carbon monoxide, nitrogen oxide and the like can be reduced, and the energy is saved and the environment is protected.
In particular, the burner 12 is used to provide stable support. In an embodiment of the present invention, the first gas chamber 122 may serve as an outer annular cavity of the burner 10, and the fire lid portion 16 may serve as an outer annular fire lid of the burner 10.
The burner cap portion 16 with the hub structure 162 is simple in manufacturing process, relatively low in cost, and strong in metal fatigue resistance.
The plurality of arms 164 ensure the strength of the burner cap 16 and the fire of the gas when the gas is burned at the fire hole 1642.
In the embodiment of the present invention, the top surface of the arm 164 includes a first inclined surface 1644 and a second inclined surface 1646, the first inclined surface 1644 connects to the second inclined surface 1646, the slope of the first inclined surface 1644 is greater than that of the second inclined surface 1646, and the fire holes 1642 are formed on the first inclined surface 1644 and the second inclined surface 1646. Thus, when the gas sprayed from the fire holes 1642 on the support arms 164 is combusted, flames with different spraying directions can be formed, the heating area of the burner 10 is increased, and the combustion heating efficiency is ensured.
In some embodiments, the burner cap portion 16 defines a plurality of gas passages 166 that diverge outwardly from the first gas chamber 122, each gas passage 166 communicates the burner hole 1642 with the first gas chamber 122, and each gas passage 166 defines a corresponding one of the legs 164.
As such, the combustion gases in the first gas chamber 122 pass through the combustion gas passage 166 to the fire holes 1642.
In the embodiment of the present invention, the fire holes 1642 formed outside the support arms 164 are independent from each other, the gas channels 166 correspondingly disposed in the support arms 164 can independently supply gas to the corresponding fire holes 1642, the gas in the first gas chamber 122 is output to the corresponding fire holes 1642 through the independent gas channels 166, and is combusted at the fire holes 1642, so that sufficient secondary air supplement is ensured to the gas in each gas channel 166, complete combustion is completed, energy waste is reduced, and user cost is reduced.
Meanwhile, the gas in the first gas chamber 122 is dispersed to complete combustion, and carbon monoxide and nitrogen oxide generated by incomplete combustion of the gas can be reduced, so that the threat to the environment and human body is avoided.
In some embodiments, the fire cover portion 16 includes an upper cover 168 and a lower cover 169 coupled to each other, the lower cover 169 being disposed over the first gas chamber 122 and the air supply portion 14, the upper cover 168 being formed with a plurality of upper cover arms 1682, the lower cover 169 being formed with a plurality of lower cover arms 1692, each upper cover arm 1682 being coupled to a corresponding one of the lower cover arms 1692 to form an arm 164, and fire holes 1642 being formed in the top surface of the upper cover arms 1682.
Thus, each upper cover arm 1682 is connected with a corresponding lower cover arm 1692 to form an arm 164, a secondary air inlet channel 18 is formed between two adjacent arms 164, and air in the air supply part 14 enters the secondary air inlet channel 18 from the lower cover 169 and reaches the fire holes 1642 on the top surface of the upper cover arms 1682, so that the secondary air can be fully supplied by the gas at the fire holes 1642, and the combustion is more sufficient.
It will be appreciated that a gas channel 166 is defined between each upper cover arm 1682 and the corresponding lower cover arm 1692, and gas enters the gas channel 166 and then reaches the fire holes 1642 on the top surface of the upper cover arms 1682 for combustion.
