Description

Energy-saving gas stove

Technical Field

The invention belongs to the technical field of gas cookers, and particularly relates to an energy-saving gas stove.

Background

The use of the energy-saving technology of the gas cooker exists in the whole process of using and improving the combustion skill. The progress of the combustion skill takes two common modes of the combustion skill as a compendium, namely an atmospheric combustion mode and a full-premix combustion mode, shows the development history of the energy-saving progress of the gas cooker in different periods, and the use of the two modes is the guarantee of obtaining the high thermal efficiency target of the combustion of the cooker and is also the main characteristic of the energy-saving skill use of the gas cooker.

Atmospheric combustion, also called partial premixed combustion skill, is characterized in that fuel gas converges into axial rotational flow in an injection pipe by virtue of the high-speed turbulent flow effect of kinetic energy in injection, and the axial rotational flow flows into air after being dispersed, and becomes stable combustible mixed gas in a combustion disc and a fire cover. In the atmospheric combustion mode, the remaining air factor is usually lower than 1 (about 0.6), so continuous filling with secondary air is required, the dependence on air filling is quite high, and the thermal efficiency of the atmospheric burner is usually low because the air flow takes away some heat. When the gas cooker is used in daily life, due to the fact that the family population is small, the cooking amount is small, dishes are often gathered in the middle of a pot, most of existing gas cookers can only adjust the flame size, after the flame is adjusted to be large, the outer ring of a stove hole is ignited, most of heat cannot be transmitted to the dishes to be dissipated, after the flame is adjusted to be small, only the central stove hole is ignited, but the air supply amount is reduced, so that firepower is insufficient, and the requirement for quick frying of the dishes cannot be met.

In view of this, the invention provides an energy-saving gas stove, which solves the technical problems.
