Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of burners, and relates specifically to a burner for a gaseous fuel-burning fireplace.BACKGROUND ART

[0002] In recent years, fireplaces having dual functions of decoration and heating have become increasingly popular, especially real-fire gas fireplaces and real-fire alcohol fireplaces which have become a first choice for decoration and heating in the home due to their clean and hygienic use, stable combustion, and high thermal efficiency utilization. In order to make combustion sufficient and easy to control in real-fire alcohol fireplaces, generally, a liquid alcohol fuel is vaporized and then introduced into a burner for combustion.

[0003] However, basically all of the burners for burning gaseous fuel currently available on the market have flames directly burning on metallic burners, or have an elongated shape or a circular shape. The burners are flat, the flames are relatively rigid and insufficiently lively, and there is no graduated feeling. Furthermore, there is a lack of decoration of simulated solid fuels and lack of harmonious correspondence between flames and fuels, and there is an unnatural feeling that flames appear out of nowhere. Even if a mode in which a plurality of burners are combined to form a flame appears on the market, it is necessary to separately introduce gaseous fuel for combustion. The structure is complicated, and the installation is complicated.

[0004] EP 4 265 963 A1 provides a burner for burning gaseous fuel comprising a first, bottom, burner and at least one upper, pistol, burner. The first, bottom, burner and the at least one upper, pistol, burner are formed from a unitary tubular material and are coupled to each other by at least one fold in the tubular material.

[0005] WO 2022 / 269521 A1 discloses a fireplace system comprises a burner comprising an upper portion shape and a front sloping surface sloping downwardly; and / or a log comprising a recess disposed into a bottom surface of the log. The recess may comprise a recess shape complementary to at least a portion of the upper portion shape of the burner, wherein the log may be disposed over the burner such that at least a portion of the burner is disposed within the recess. The burner may be disposed in the recess of the log such that the log hides the burner from view from a position in front of the fireplace system.

[0006] US 6 048 195 A discloses a combined log set and gas burner system, which comprises a plurality of reinforced ceramic fiber burner elements formed in the shape of artificial logs and or glowing embers or a non-porous bed of coals. The burner elements are formed with a gas passageway in the interior of the element and a plurality of gas jets are made which connect the surface of the burner elements to the gas passageway in the burner elements. A source gaseous fluid is connected to the passageways to complete the combination burner system which eliminates the need for a separate burner apart from the log system.CONTENT OF INVENTION(I) Technical problem to be solved
