Abstract:
(EN) Disclosed is a burner and a gas water heater having same, the burner comprising a mixed flow passage (10), a connecting chamber (30) and a mixing chamber (20) connected in sequence, wherein the other end of the mixed flow passage (10) is provided with a gas inlet (11) for introducing gas, the connecting chamber (30) is curved and connects the mixed flow passage (10) and the mixing chamber (20), and the mixed flow passage (10) and the mixing chamber (20) are located on the same side of the connecting chamber (30); the centre line of the mixed flow passage (10) is a first centre line, the centre line of the mixing chamber (20) is a second centre line, and the cross section of the mixed flow passage (10) passing through the second centre line and perpendicular to the plane where the first centre line and the second centre line are located is a first cross section; and two side edges of the first cross section expand from the gas inlet (11) toward the connecting chamber (30), and an included angle formed by extension lines of the two side edges of the first cross section is a first included angle (a), the angle of the first included angle (a) being less than or equal to 3 degrees. The burner improves the gas mixing efficiency in the mixed flow passage (10) and the combustion performance of the burner.
(FR) L'invention concerne un brûleur et un chauffe-eau à gaz comportant ledit brûleur, le brûleur comprenant un passage d'écoulement mélangé (10), une chambre de liaison (30) et une chambre de mélange (20) reliés en séquence, l'autre extrémité du passage d'écoulement mélangé (10) étant munie d'une entrée de gaz (11) servant à introduire un gaz, la chambre de liaison (30) étant incurvée et reliant le passage d'écoulement mélangé (10) et la chambre de mélange (20), le passage d'écoulement mélangé (10) et la chambre de mélange (20) étant situés du même côté de la chambre de liaison (30) ; la ligne centrale du passage d'écoulement mélangé (10) est une première ligne centrale, la ligne centrale de la chambre de mélange (20) est une seconde ligne centrale, et la section transversale du passage d'écoulement mélangé (10), passant par la seconde ligne centrale et perpendiculaire au plan où se situent la première ligne centrale et la seconde ligne centrale, est une première section transversale ; deux bords latéraux de la première section transversale s'étendent de l'entrée de gaz (11) vers la chambre de liaison (30), et un angle inclus formé par des lignes d'extension des deux bords latéraux de la première section transversale est un premier angle inclus (a), le premier angle inclus (a) étant inférieur ou égal à 3 degrés. Le brûleur améliore l'efficacité de mélange de gaz dans le passage d'écoulement mélangé (10) et le rendement de combustion du brûleur.
(ZH) 一种燃烧器和具有其的燃气热水器,该燃烧器包括依次贯通的混合流道(10)、连接腔(30)和混合腔(20),混合流道(10)的另一端设有用以气体通入的进气口(11),连接腔(30)呈弯曲状并连接混合流道(10)与混合腔(20),且混合流道(10)与混合腔(20)位于连接腔(30)的同一侧,混合流道(10)的中心线为第一中心线,混合腔(20)的中心线为第二中心线,混合流道(10)的过第二中心线且垂直于第一中心线与第二中心线所在平面的截面为第一横截面,第一横截面的两侧边自进气口(11)处向连接腔(30)扩张,第一横截面的两侧边的延长线形成的夹角为第一夹角(a),第一夹角(a)的角度小于或等于3度。该燃烧器提高了混合流道(10)内气体混合效率及燃烧器的燃烧性能。
