Embodiment 1

[0040] Such as Figure 1~6 As shown, a gas stove with an array of parallel flame inner flame burners, the inner flame burner 1 at least includes an array of parallel flame flame dividers 1.1 and a burner body 1.2, and the gas stove at least includes an inner flame burner 1 with an array of parallel flames and a gas The main body of the stove 2; the array parallel flame distributor 1.1 is installed on the top of the burner body, on the outer surface inside the top of the array parallel flame distributor, there is an array surface composed of 8 slopes 1.1.1, and each Two rows of circular fire holes 1.1.2 are provided on a slope. In the same row of fire holes, the fire hole fluid passages between the fire holes and the fire holes are parallel to each other, and the airflow direction at the fire hole outlet is consistent; The included angle between the axis and the horizontal plane is not more than 90 degrees, and it is preferred to choose within the angle range of 20 to 75 degree...

Embodiment 2

[0042] Such as Figure 7 , 8 As shown, the only difference from Embodiment 1 is that the array surface of the array parallel flame distributor is a composite curved surface, and the composite curved surface is composed of two slopes 1.1.1a and 1.1.1b with different inclination angles. Between adjacent composite curved surfaces There is a groove-shaped airflow channel 1.1.3a, two rows of fire holes are respectively distributed on the slope 1.1.1a, 1.1.1b, and the outer ring is in a circular shape 1.1.5a.

Embodiment 3

[0044] Such as Figure 9 As shown, the only difference from Embodiment 1 is that the array surface of the array parallel flame distributor is a composite curved surface, and the composite curved surface is composed of two slopes 1.1.1a and 1.1.1b with different inclination angles. Between adjacent composite curved surfaces There is a through-hole airflow channel 1.1.3, and two rows of fire holes are respectively distributed on the slopes 1.1.1a and 1.1.1b.

Abstract

An inner flame burner at least comprises an array parallel flame distributor and a burner main body. An array surface formed by a plurality of inclined planes, a plurality of curved surfaces or a plurality of composite curved surfaces is arranged on the outer surface of the inner side of the top of the array parallel flame distributor; every inclined plane, every curved surface or every composite curved surface, which forms the array surface, is at least provided with one row of fire holes; fire hole fluid channels between the fire holes among the same row of fire holes are parallel to each other, and the air flow directions of fire hole outlets are consistent or substantially consistent; and air flow channels are arranged between the adjacent inclined planes, curved surfaces or composite curved surfaces. An array parallel flame combustion technology is adopted, layered oxygen supplementation and layered combustion are adopted, the effects of improving air supplementation and burning temperature fields, restraining NOx generation and improving heat efficiency of a cooker are remarkable, the inner flame burner is novel and unique in design and high in view angle impact, fire power is high and concentrated, heat efficiency is over 60%, CO and NOx discharge is low, and the standard requirements of energy-saving environment-friendly cookers are completely met.

Description

technical field [0001] The invention relates to a gas stove, in particular to a gas stove with an array of parallel flame inner flame burners. Background technique [0002] At present, gas stoves generally use partial premixed atmospheric burners. In order to improve the energy-saving effect of gas stoves, the inner flame burner which concentrates the flame to the central area of ​​the burner has received widespread attention. In the existing internal flame burner, the fire holes are mostly distributed along the circumference of the burner, and between adjacent fire holes, the flames will intersect along the exit direction. Although this combustion structure can significantly improve the thermal efficiency of the cooker, it is more difficult to control the CO and NOx content in the flue gas than the non-inner flame burner. [0003] The standards for energy-saving and environmentally friendly gas stoves proposed by the Ministry of Environmental Protection: thermal efficienc...
