Cooking fume recirculation type energy-saving gas stove

Abstract

The invention provides a cooking fume recirculation type energy-saving gas stove. The cooking fume recirculation type energy-saving gas stove comprises a stove base, a combustor, a range hood, a negative-pressure pump, an automatic cooking fume detection and control valve and a safety valve. The stove base is of a cylindrical structure. The upper portion of the stove base is of a downward-concavespherical surface structure, and the downward-concave spherical surface is coated with a radiative heat-dissipation paint coating. A hollow annular heat insulation layer is arranged on the stove base.The combustor is arranged at the center of the downward-concave spherical surface, and the lower portion of the combustor is connected with a gas and air premixing pipeline. A spiral preheating pipeis wound outside the gas and air premixing pipeline. One end of the preheating pipe is connected with the negative-pressure pump, and the other end of the preheating pipe is connected with the hollowannular heat insulation layer through a smoke return pipe. The range hood is arranged over the stove base. A smoke pipe is guided out from a smoke discharging pipeline of the range hood and is connected with the automatic cooking fume detection and control valve. One path of cooking fume from the automatic cooking fume detection and control valve is discharged through a first pipeline, and the other path of the cooking fume is connected to the safety valve through a second pipeline and then is connected to the gas and air premixing pipeline.

Description

technical field [0001] The invention belongs to the technical field of gas stoves, and relates to a gas stove, in particular to an oil fume recirculation energy-saving gas stove device. Background technique [0002] The rapid development of the global industrialization process has led to a large amount of energy consumption, and the problem of energy shortage has become more and more obvious. Although the use of new energy sources is being continuously developed, coal, oil, and natural gas, which are the mainstream energy sources, still occupy a dominant position in global energy sources, and these three mainstream energy sources are all non-renewable resources. Under constant consumption, its storage capacity is getting less and less, and energy saving has become a theme of social development at this stage. In our country, the use of gas is very extensive, especially the use of household gas cookers occupies a very large proportion. The average thermal efficiency of gas s...
