ース内に設ける構成が一般的である。<Conventional technology> Generally, household gas appliances used for water heaters, bath kettles, etc., have a fan installed in an intake / exhaust passage to forcibly supply and exhaust combustion air. Type gas appliances are known. This forced-combustion gas appliance has been widely used as a household gas appliance because the heat-absorbing property of the heat exchanger is increased as compared with the natural exhaust type, and the appliance is reduced in size and increased in capacity. In this case, the gas burner incorporated in the gas appliance generally has a configuration in which a gas burner body having a slit flame hole is provided in a burner case.

た。<Problems to be Solved by the Invention> However, in order to increase the load on the gas burner due to the demand for high performance and small size of household gas appliances, if this gas burner body is provided at a high density, secondary gas shortage will occur. Red fire combustion occurred, and it was difficult to achieve stable combustion.

滑と行かず(均一供給が難しい)、安定した炎が得がた
く、且つリフティングが生じ易い。In recent years, in order to improve the above-mentioned defects, a mixing section for introducing primary air is provided at a lower portion, and a divergent flame holding plate having a V-shaped cross section for introducing secondary air from a side is provided at an upper portion. A new forced-burning type gas burner has been developed in which a large number of gas burners (burners only) are arranged side by side in a gas case. However, the supply of secondary air during combustion is not smooth (uniform). Supply is difficult), stable flame is difficult to obtain, and lifting is liable to occur.
更に、従来のガスバーナで特に問題となる点は、各種
ガスの種類(都市ガス・13A,6C、プロパンガス等)に応
じる燃焼速度の変化に追従し得ないものである。Further, a point that is particularly problematic in the conventional gas burner is that it cannot follow a change in the burning rate depending on the type of various gases (city gas, 13A, 6C, propane gas, etc.).
本発明は上記実状に鑑み、ガスバーナ単体の保炎板に
流入する二次空気の制御部材を取付け、上記課題を解決

In the gas burner, a large number of slit vertical holes for supplying secondary combustion air are vertically arranged in the flame holding plate, and a small gap is formed between the slit vertical holes on the combustion surface side. Thus, a flame holding member that covers the lower portion of the slit vertical hole and regulates the flow of secondary air at the lower portion of the slit vertical hole is provided.

The secondary air is raised into the case to form secondary air, and the secondary air flows into each intermediate position of the burners arranged in a row in the burner case. It will flow into the inside through the slit vertical hole, but in this case, inside the flame holding plate,
The lower part of the slit vertical hole is covered with a flame holding member, so that a flame holding effect is provided to suppress the burning speed and prevent the lifting of the flame.

業が容易となる。Here, the primary air of the air chamber 29 flows out to the gas inlet 5 of the gas burner body 4 together with the combustible gas appropriately ejected from the gas nozzle 27, and the inside of the gas burner body 4 from the mixing section 6 to the comb-like member at the position of the separator 10 From the gap b formed in the notch 11a of FIG.
Where the gas and primary air collide,
In a flow such as deceleration, the gas and the primary air are completely mixed. On the other hand, the secondary air flowing just above the air inflow section 2 is
Uniform rectification is achieved by the flow through the holes in the punch metal surface 23 on the lower surface of the secondary air distribution device 20 set in a filter shape in the arrangement gap 22 of each gas burner body 4 and the vertical holes in the aluminum honeycomb portion 24 inside this. The secondary air that has passed through the honeycomb portion 24 is uniformly raised over the entire area of the flame holding plate 9 by a uniform member 26 that is inclined upward, and uniform secondary air is supplied to the slit vertical holes 8. . However, in this case, the slit vertical hole 8
At the base of the surface position, a flame holding member 12 mounted on the inside of the separator 10 covers through a small interval a, and a claw portion 12a protruding from an edge of the flame holding member 12 has a slit vertical hole. 8, the flow of secondary air is regulated, and combustion corresponding to various gases having different combustion rates can be performed, and lifting is also prevented. In this case, the shape of the flame holding member 12 is shown in FIG.
As in the other embodiments shown in FIGS. A and B, both side walls 10a of the gutter-shaped separator 10 are raised in the form of a broken step, and the protruding side portion 1 is formed.
0b may be used as the flame holding member 12. In this case, the flame holding member 12 may be separate. With such an integral structure, the assembling work becomes easy.

で燃焼する。Of course, the combustion of this gas is ignited by the spark of the ignition plug 35 attached to the upper end of the burner case 1.
The slit vertical hole 8 of the flame-holding plate 9 near the mounting position of the ignition plug 35 has a narrow width, the flow rate of the secondary air at that portion is reduced, and the fire transfer to the gas burner body 4 at each stage is improved. Further, secondary air is supplied in a rectified state by the burring surface 31 formed in the slit vertical hole 8 of the flame holding plate 9, so that stable combustion without red fire combustion is achieved. Further, even if the unburned gas reaches the upper end of the flame holding plate 9, it burns with the secondary air blown out from the horizontal slit opening 33 of the horizontal plane 18 a of the upper end of the flame holding plate 9.
