Description

Technical Field

[0001] This utility model relates to the field of burners, and specifically to an annular swirling flame burner. Background Technology

[0002] When the burner of a gas stove is working, gas enters the stove through the gas inlet pipe, is regulated by the gas valve, and then enters the burner head, mixing with a portion of air. This mixture is then drawn from the flame of the burner. In the hole The ejected material is ignited by an ignition device to form a flame. The ignition device typically includes a microswitch that is energized by a knob and an ignition needle that provides ignition.

[0003] Traditional bottom-intake burners have various problems, so more and more gas stoves are starting to use top-intake burners, where the primary air for gas mixing and the secondary air required for combustion are both supplied from above the burner base.

[0004] Existing burners, such as CN102661606A, have multiple outer ring injectors (supplying gas to the outer ring of the burner) to provide sufficient gas, resulting in an excessively large burner size, making it unsuitable for smaller gas stoves. Furthermore, its combustion chamber does not guide the inner and outer ring flames; it only has a cavity for gas flow.

[0005] Therefore, the inventors conducted further research and developed an annular swirling flame burner, which led to this invention. Utility Model Content

[0006] The purpose of this invention is to provide an annular swirling flame burner that can effectively improve combustion thermal efficiency.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] An annular swirling flame burner, comprising

[0009] The combustion chamber is equipped with an inner ring burner cap and an outer ring burner cap. The inner ring burner cap and the combustion chamber form an inner ring cavity, and the outer ring burner cap and the combustion chamber form an outer ring cavity. Both the inner and outer ring cavities are provided with several oblique tooth-shaped channels, which are distributed in a ring around the combustion chamber.

[0010] In the field of burners, the basic structure is already a mature technology. It involves supplying gas to the corresponding inner or outer ring burner cap through nozzles. By improving the internal structure of the combustion chamber, the burner layout can be made more compact and reasonable, forming a double-ring flame with a rotating flow direction. This increases the time it takes for the high-temperature flame to flow out from the bottom of the pot, thus increasing the heat exchange time between the flame and the pot.

[0011] Further, the inclined tooth-shaped channels of the outer ring cavity are formed in the combustion chamber, and the inclined tooth-shaped channels of the inner ring cavity are formed under the inner ring fire cover.

[0012] The forming here is also relative to the integrated structure.

[0013] Further, the circumferential directions of the inclined tooth-shaped channels in the inner ring cavity and the outer ring cavity are the same or opposite.

[0014] If the counter-clockwise or clockwise inclined tooth-shaped channels are formed, the circumferential directions of the inner ring cavity and the outer ring cavity are opposite to the aforementioned directions.

[0015] Further, the combustion chamber and the outer ring fire cover form an annular flame exit, and a flame stabilizing groove is arranged at the lower part of the annular flame exit, and a through hole is arranged in the flame stabilizing groove and communicates with the inside of the combustion chamber.

[0016] Further, the inner ring cavity is supplied with gas by an inner ring pipe, and the outer ring cavity is supplied with gas by two outer ring pipes, the inner ring pipe and the outer ring pipes are arranged below the combustion chamber, the outer ring pipes are arranged on both sides of the inner ring pipe, and the inlet directions of the two outer ring pipes are opposite.

[0017] While ensuring sufficient gas supply of the combustion chamber, the structure is as compact as possible.

[0018] Further, a base is further arranged below the combustion chamber, the base is provided with an inner ring nozzle and an outer ring nozzle, the inner ring nozzle corresponds to the inner ring pipe, and the outer ring nozzle corresponds to the outer ring pipe.

[0019] Further, a gap is arranged between the base and the combustion chamber, and air enters the combustion chamber from the gap.

[0020] Further, a flame jet is arranged at the center position of the inner ring fire cover.

[0021] After the above scheme is adopted, compared with the prior art, the present application has the following advantages:

[0022] When the burner works normally, the double annular flames with rotating flow directions are formed, the time of the high-temperature flame flowing out from the bottom of the pot is lengthened, the heat exchange time of the flame and the pot is increased, and thus the combustion heat efficiency is effectively improved.
