Specifically, as shown in fig. 2 and 3, the upper and lower combustion plates 100 and 200 are each disc-shaped, the air inlet 230 is located at the center of the lower combustion plate 200, the plurality of fire holes 220 are located at the outer circumferential edge of the combustion body 21, and the plurality of fire holes 220 are arranged in a ring shape around the flow passage 210 in the circumferential direction of the combustion body 21, i.e., a plurality of fire holes 220 are defined between the outer circumferential edge of the upper combustion plate 100 and the outer circumferential edge of the lower combustion plate 200.
Further, as shown in fig. 2, a guide cover 240 extending downward around the air inlet 230 is provided on the lower combustion disk 200, and after the fuel gas is sprayed out from the nozzle, the fuel gas can enter the flow channel 210 through the air inlet 230 under the guidance of the guide cover 240, so as to prevent the fuel gas from diffusing and being lost.
In some specific examples of the present invention, as shown in fig. 2, the water discharge nozzle 110 is provided on the upper burner tray 100, for example, the water discharge nozzle 110 may be integrally formed with the upper burner tray 100, the lower end of the water discharge nozzle 110 is provided with a hook edge 112, the hook edge 112 may be formed by folding the lower end of the water discharge nozzle 110 outwards, the lower end of the water discharge nozzle 110 passes through the lower burner tray 200 and the hook edge 112 is hooked on the lower burner tray 200, thereby the lower burner tray 200 may be connected by the hook edge 112, the upper burner tray 100 and the lower burner tray 200 may be further connected at a position other than the installation positions of the upper burner tray 100 and the lower burner tray 200, thereby further improving the overall structural strength of the combustion body 21, and being convenient to process and assemble, and having high structural reliability.
In some embodiments of the present invention, as shown in fig. 2, the portion of the upper burner tray 100 where the upper edge of the fire hole 220 is formed is bent upward, and the portion of the lower burner tray 200 where the lower edge of the fire hole 220 is formed is bent downward. In other words, the outer circumference of the upper burner tray 100 is curved upward, and the outer circumference of the lower burner tray 200 is curved downward. Thus, a flame stabilizing structure is formed, and when the flame holes 220 are burned, the flame is spread outwardly at the flame holes 220 and fills up a portion between the outer circumferential edge of the upper burner disc 100 and the outer circumferential edge of the lower burner disc 200, enlarging the root of the flame, and thus the flame is stably burned.
In some specific examples of the present invention, as shown in fig. 2, the flow passage 210 includes a mixing chamber 211 and a diffusion chamber 212 in communication with each other, an air inlet 230 in communication with the mixing chamber 211 and a fire hole 220 in communication with the diffusion chamber 212. In other words, the mixing chamber 211 is located at the center of the combustion body 21, the diffusion chamber 212 is disposed around the diffusion chamber 212, and the plurality of flame holes 220 are disposed around the diffusion chamber 212. The fuel gas is sprayed from the nozzle under a certain pressure and a certain flow speed, the fuel gas sucks primary air by self energy, the fuel gas and the air enter the mixing cavity 211 from the air inlet 230 to be mixed, the mixed gas enters the diffusion cavity 212 to be pressurized, and finally the mixed gas is burnt at the fire hole 220.
In some specific examples of the present invention, as shown in fig. 2 and 3, the upper combustion disk 100 is provided with an outer upper protrusion 120 corresponding to the position of the diffusion chamber 212 and protruding upward, and the lower combustion disk 200 is provided with an outer lower protrusion 250 corresponding to the position of the diffusion chamber 212 and protruding downward, and the outer upper protrusion 120 and the outer lower protrusion 250 respectively extend in a ring shape in the circumferential direction of the combustion body 21 and define the diffusion chamber 212 together. The upper combustion disk 100 is further provided with an inner upper protrusion 130 protruding upward and corresponding to the position of the mixing chamber 211, the projection of the inner upper protrusion 130 in the horizontal plane is circular, the central axis of the inner upper protrusion 130 coincides with the central axis of the air inlet 230, the inner upper protrusion 130 forms the upper wall of the mixing chamber 211, and the outer upper protrusion 120 is arranged around the inner upper protrusion 130.
The upper combustion disk 100 is further provided with a lower concave portion 140 recessed downward corresponding to the position of the junction of the diffuser chamber 212 and the mixing chamber 211, the lower concave portion 140 extending in a ring shape along the combustion body 21 and being located between the outer upper convex portion 120 and the inner upper convex portion 130 in the radial direction of the combustion body 21, and the drain nozzle 110 being located on the lower concave portion 140. The condensed water thus dropped on the upper burner tray 100 can flow to the lower concave portion 140 under the guidance of the outer and inner upper convex portions 120 and 130 and be discharged from the drain nozzle 110 on the lower concave portion 140, so that the condensed water on the upper burner tray 100 can be further drained, preventing the condensed water from accumulating on the burner 20.
Alternatively, the outer and inner upper protrusions 120 and 130 may be protruded upwardly in a substantially circular arc shape, respectively, and the lower concave portion 140 may be recessed downwardly in a substantially circular arc shape, with a circular arc transition therebetween.
Further, as shown in fig. 3, in order to further improve the water discharge effect, a plurality of water discharge nozzles 110 are provided, and the plurality of water discharge nozzles 110 are provided at equal intervals in the circumferential direction of the combustion body 21 on the concave portion 140.
In some specific examples of the present invention, as shown in fig. 2 and 3, the upper combustion disk 100 is provided with a guide portion 150 corresponding to the position of the air inlet 230 and recessed downward, and the guide portion 150 may be in the shape of a sphere and disposed at the center of the inner upper protrusion 130. After entering the mixing cavity 211 from the air inlet 230, the combustion mixture can be changed from the vertical flow direction to the horizontal flow direction under the guidance of the guide part 150, so that the flow of the combustion mixture is smoother and the mixing of the fuel gas and the air is facilitated.
As will be appreciated by those skilled in the art, since the concave guide 150 is located at the center of the upper burner tray 100, condensed water generated on the wall surface of the flue 11 generally drops at the outer periphery of the upper burner tray 100, i.e., does not drop at the center of the upper burner tray 100, the condensed water at the outer periphery of the upper burner tray 100 flows toward the concave recess 140 under the guidance of the outer and inner upper protrusions 120 and 130, and thus, condensed water does not accumulate at the guide 150.
According to the burner 20 of the embodiment of the present invention, the fuel gas is injected through the nozzle, enters the combustion body 21 through the air inlet 230 at the center of the lower burner tray 200, enters the mixing chamber 211 through the guide part 150, and enters the fire hole 220 through the diffusion chamber 212 for combustion. When the primary cold state is burnt, the high temperature flue gas contacts the wall surface of the cold inner container 10 (i.e. the wall surface of the flue 11), so that the water vapor of the high temperature flue gas is condensed and adheres to the wall surface of the inner container 10, and as time goes by, the condensed water is more and drops downwards and falls on the burner 20, and then flows to the ground through the drainage channel 111 of the drainage nozzle 110, thereby avoiding the influence on the combustion flame caused by long-term stay and accumulation of the condensed water. When the flame burns through the flame hole 220 with the flame stabilizing structure, the flame is outwards diffused at the flame hole 220 and fills the flame stabilizing hole, so that the flame root is enlarged, and the flame forms stable combustion.
