Dual ring combustion system preventing dry fry

Abstract

The invention relates to a burning system, in particular to a double-ring burning system used for protecting against dry heating. The double-ring burning system comprises a burner provided with a fuel gas channel, a fire shield seat arranged on the burner, an outer ring fire shield arranged on the annular fire shield seat, a temperature sensor arranged at the center of the burner, and an inner ring fire shield that is arranged on the burner and used for protecting the temperature sensor; a round through hole is arranged at the center of the inner ring fire shield, an annular fuel gas chamber that is separated with the through hole is arranged outside the through hole, a gas inlet that is communicated with the fuel gas channel is arranged at one end of the fuel gas chamber, and at least one circle of inner burning orifices are arranged on the outer wall of the fuel gas chamber and communicated with the fuel gas chamber. The invention provides the double-ring burning system used for protection against dry heating, can eliminate the influence of inner ring fire on the temperature sensor arranged at the center of the burner, can improve the heating capability of the burner, and can simultaneously avoid the problems of overproof carbon monoxide and inner ring yellow flame caused by the air insufficiency of the inner ring fire.

Description

Technical field [0001] The invention relates to a combustion system, in particular to a double-ring combustion system for preventing dry burning. Background technique [0002] The traditional combustion system uses a multi-ring fire to heat the kitchen utensils placed on it, but when the anti-dry burning technology is applied to the above-mentioned combustion system, a temperature sensor needs to be installed at the center of the combustion ring of the combustion system, so that the temperature sensor is in working state It will be severely affected by the temperature of the inner ring fire in the combustion ring, so a single outer ring fire is generally used in the anti-dry burning combustion system. At the same time, there are also technical solutions that use the above-mentioned temperature sensor on the multi-ring fire combustion system, but it cannot eliminate it. The influence of inner ring fire on the temperature sensor installed in the center [0003] For example, the pat...

Problems solved by technology

[0002] The traditional combustion system uses a multi-ring fire to heat the kitchen utensils placed on it, but when the anti-dry technology is applied to the above-mentioned combustion system, it is necessary to set a temperature sensor at the center of the combustion ring of the combustion system, so that the temperature sensor is in the working state. It will be seriously affected by the temperature of the inner ring fire of the combustion ring, so generally only a single outer ring fire is used in the anti-dry combustion system; at the same time, there are also technical solutions for setting the above-mentioned temperature sensors on the multi-ring fire combustion system, but it cannot be eliminated. The influence of the inner ring fire on the temperature sensor set in the center

[0003] For example, the patent No. is CN2756915YY, although the above-mentioned patent named as the temperature sensing mechanism of the gas stove adopts the protection device that protects it and is arranged on the central temperature sensor, it cannot eliminate the flame of the combustion system that is arranged at the center of the combustion system. The impact of the temperature sensor; the patent No. is JP11063506A, and the Japanese patent named gas stove also discloses a combustion system, which adopts an umbrella-shaped canopy to protect the temperature sensor arranged at the center of the combustion system, but it also The influence of the flame of the combustion system on the temperature sensor located at the center of the burner cannot be eliminated
