Abstract

The utility model provides an energy-saving gas cooking range which belongs to the technical field of a gas cooking tool and mainly solves the problem that mixed gas is not uniformly mixed, soft fire is combusted inadequately and the thermal efficiency is lower. The energy-saving gas cooking range comprises a hearth, a fire-jet head, a constant open fire hood, a constant open fire mixed gas tube and an ignition line. The energy-saving gas cooking range is characterized by further comprising a guide hood in interference fit with a bump below the fire-jet head and a gas mixing chamber located below the guide hood. The bottom of the fire-jet head is a downward concave spherical surface. The upper part of the guide hood is further a downward concave spherical surface. The bottom of the gas mixing chamber is an upward concave spherical surface. The structure ensures that the mixed gas is uniformly mixed. A combustion-supporting fire jet hole is arranged on the side face of the downward concave spherical surface of the fire-jet head to ensure ignition of a main fire. The energy-saving gas cooking range is stable in combustion in soft fire, and the thermal efficiency is higher.
