Efficient energy-saving gas cooker

Abstract

The invention relates to an efficient energy-saving gas cooker which comprises a gas cooker core, wherein an energy-saving water ring is increased at the periphery of the gas cooker core for enhancing the heat transfer of the gas cooker, and water in the water ring is used for absorbing excessive heat. The center of flame of the gas cooker core is located at the arc position of the energy-saving water ring. One side of the energy-saving water ring, close to the frame of the cooker core, is semi-spherical. As the energy-saving water ring is increased at the periphery of the gas cooker core for enhancing the heat transfer of the gas cooker, and the water in the water ring is used for absorbing excessive heat, on one hand, hot water can be taken out for washing vegetables, dishes and the like; and one the other hand, the hot water can be placed in the water ring, and after the flame goes out, the remaining heat of the hot water can be used for preserving the temperature of meals. In the invention, principles of heat transfer theory, engineering thermophysics, optical physics, combustion science, material mechanics and the like are applied; the realized device has the advantages of simple production process, low production cost and stable working performance; moreover, the efficient energy-saving gas cooker has an energy-saving effect and is suitable for the energy-saving concept.

Description

technical field [0001] The invention relates to a gas stove, in particular to an energy-saving gas stove. Background technique [0002] Household gas stoves rely on flames (mainly through heat conduction and convection) to heat objects (bottoms of pots or pots), but the contact between the flames and objects is only momentary, and a large amount of heat is dissipated into space without being used (mainly in the form of radiation) and convection), a phenomenon known as "thermophysical loss". When the gas stove is burning, heat will leak from the bottom of the pot and the periphery of the flame radiation area, which not only causes energy waste, but also increases the kitchen temperature in summer, affecting human comfort. [0003] Gas stove hydrosphere devices have been produced since the 1980s, and were widely used at that time. Most of the devices were used in rural households. Such devices are simple in process, cheap in cost, and convenient to use, but they have ene...
