Porous medium gas cooker based on spherical accumulation

Abstract

The invention belongs to the field of kitchen utensils, and discloses a porous medium gas cooker based on spherical accumulation. The cooker comprises an internal stove cavity, an external stove cavity, an external gas injector, an internal gas injector, a porous medium filling bed body and an ignition device, the outer stove cavity sleeves the inner stove cavity, an outer ring of the porous medium filling bed body comprises a first supporting hole plate, a preheating area and a first combustion area which are sequentially arranged on the upper portion of the external stove cavity, an inner ring of the porous medium filling bed body comprises a second supporting hole plate and a second combustion area which are sequentially arranged on the upper portion of the internal stove cavity, spheres fill the preheating area, the first combustion area and the second combustion area, and the porosity of the preheating area is greater than that of the first combustion area. According to the cooker, a porous medium combustion region is formed through spherical accumulation, steady air flow and temperature gradient are formed by constructing the porosity in step form of the combustion region, the combustion intensity is improved, the stability of the flame is enhanced, the emission of nitrogen oxide and carbon monoxide is reduced, and therefore higher environmental-protection and economicalbenefits are achieved.

Description

technical field [0001] The invention relates to the field of gas cookers, in particular to a porous medium gas cooker based on sphere stacking. Background technique [0002] Gas stoves refer to kitchen utensils that are heated directly by gaseous fuels such as liquefied petroleum gas (liquid), artificial gas, and natural gas. Gas stoves are also called hobs, and their popularity is known to everyone, but it is difficult to see a common concept. The desktop cooker is mainly composed of a burner (burner head, inner and outer fire cover), valve body (including nozzle, damper plate, conical spring), shell (can be a split shell-panel, rear plate and left and right side plates) It can also be composed of an integral stretch shell), a stove frame, a knob, a liquid pan, a stove foot, an air intake pipe, and a pulse igniter (special for a pulse ignition mode cooker). When the gas stove is working, the gas enters the stove from the intake pipe, and enters the burner after being adju...

Problems solved by technology

[0003] Traditional Bunsen flame gas stoves have disadvantages such as low regulation ratio, unstable flame, and high pollution emissions. They emit NOx, CO, and unburned hydrocarbons (UHC). These emissions cause indoor air pollution and are harmful to humans.
