Description

A kind of grid turbulence energy-saving stove
Technical field
The present invention relates to a kind of cooking utensils, especially a kind of grid turbulence energy-saving stove.
Background technology
Cooking stove is a kind of cooking utensils, and its burning by fuel produces heat, thus implements heating to pot body and realize boiling to food materials in pot.Due in cooking process, can not avoid the loss of heat, the just face of usual pot body is smooth, and its heating surface area is limited, but heating intensity is larger again, therefore causes the heat absorption efficiency of pot body low; Heat utilization ratio is low, and namely heat losses is large, and cause the effective rate of utilization of the energy low, when the energy lacks increasingly, economize energy has become the primary study aspect of every field.
People improve heat absorption efficiency by various means, such as ember are converted into infrared ray and are heated to the bottom of a pan by radiation mode, by combustion gas and air pre-mixing, flame temperature are improved for another example, the heat exchange efficiency of increase and pot body.When pot surface is smooth, when high-temperature gas flows along pot body outer surface, substantially advection state is in, namely the air-flow pressed close near pot body presents " cold conditions " and presents " hot " away from the air-flow of pot body, with the flowing of opposing parallel state between " cold conditions " air-flow and " hot " air-flow, and the exchange of high temperature particle between hot and cold conditions and low temperature particle is relatively weak.
Also have by arranging a lot of leaf fin at the outer surface of pot body in addition, heat exchange efficiency is improved by increasing heat exchange area, but that is the manufacturing process complexity increasing leaf fin to pot body, and greatly can increase the manufacturing cost of pot, moreover pot body outer surface is no longer smooth after arranging leaf fin, bring significant limitation and inconvenience can to the use of pot.
Summary of the invention
Technical problem to be solved by this invention is the present situation for prior art, and provide structure simple, endothermic effect is good, a kind of grid turbulence energy-saving stove that capacity usage ratio is high.
The present invention solves the problems of the technologies described above adopted technical scheme:
A kind of grid turbulence energy-saving stove, includes stove, stove is provided with burner hearth, this burner hearth is provided with burner, burner is connected with gas inlet pipe; Burner hearth is provided with the support suitable with pot body; Be provided with grid in burner hearth, be formed with narrow slit between grid and described pot body, between grid, be formed with turbulent chamber, between burner hearth and described pot body, be provided with exhanst gas outlet; Hot-air produces turbulent flow in turbulent chamber.
For optimizing technique scheme, the concrete measure taked also comprises:
Heat-insulation layer is provided with in above-mentioned burner hearth.
Above-mentioned gas inlet pipe is connected with air intake duct.
Above-mentioned pot body is spherical structure, and grid is arranged at the bottom of described pot body.
