〔産業上の利用分野〕
本発明は、ガス給湯機などに用いる先混合式ガスバーナ
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pre-mixing gas burner used in gas water heaters and the like.
家庭用のガス給湯；幾は、設置性の向上、建物との調和
、デッドスペースの有効利用などからコンパクト化が強
く望まれている。Gas hot water heaters for home use are strongly desired to be made more compact in order to improve installation ease, harmonize with buildings, and make effective use of dead space.
従来、ガス給湯機には、空燃比の制狽１性、火炎の安定
性に対して有利なブンゼン式がスバーナが用いられ、高
負荷燃焼を可能とするために二次空気の拡散を促進する
各種の形態が提案されてきた。Traditionally, gas water heaters use a Bunsen type svarna, which is advantageous for controlling the air-fuel ratio and flame stability, and promotes the diffusion of secondary air to enable high-load combustion. Various forms have been proposed.
また、二次空気の拡散が不要となる全予混合式ガスバー
ナを利用した高負荷燃焼方式の検討も試みられている。In addition, attempts are being made to consider a high-load combustion method using a fully premixed gas burner, which eliminates the need for secondary air diffusion.

（ａをコンパクト化するには、製品に占める体積比率

(In order to make a more compact, it is necessary to downsize the combustion part, combustion space, etc., which occupy a high volume ratio in the product.

など種々の問題点があった。On the other hand, in the case of a fully premixed gas burner, there is no need to diffuse secondary air, so a short flame can be achieved, and the combustion space can be made smaller than in the case of a Bunsen burner. However, in order to maintain a balance between the ejection speed of the premixed gas from the flame mouth and the combustion speed and prevent the flame from blowing out, it is necessary to increase the air ratio (ratio of combustion air to the theoretical air value). Can not. For this reason, the combustion gas becomes high temperature, and environmental pollutants such as carbon monoxide (hereinafter referred to as CO) and nitrogen oxides (hereinafter referred to as NOx) in the combustion gas become highly concentrated, and the dew point due to low air ratio combustion. There are drawbacks such as the need for a drainage treatment device because corrosive drainage tends to occur during heat exchange between the combustion gas and water due to the increase in water. In addition, gas with a fast combustion rate may cause backfire depending on the conditions, and the dimension at which the premixed gas blows out at the flame opening must be less than the extinguishing distance, which increases the pressure loss in the burner and The disadvantage is that the fan that blows the air is large. Furthermore, there are various problems such as a need for a device for pre-mixing the fuel gas and combustion air, which increases costs.
本発明の目的は上記のような欠点がなく高負荷燃焼が可
