Abstract
The utility model discloses an energy-saving shield for a gas stove, which includes a shield body, wherein the shield body is a truncated-cone shaped shield, which is made of a carbon steel plate and provided with the upper part with a bigger diameter and a lower part with a smaller diameter; at least four foot brackets are distributed at the upper part of the shield body; and the inner wall of the shield body is coated with a metal layer having high reflectivity. Through the adoption of the utility model, the lower part of the shield body is directly seated on the stove, and the stove is placed on the foot brackets; partial energy generated by combustion is directly used for heating the bottom of the stove, and the residual energy is reflected and reaches the bottom of the stove through an annular side wall of the shield body, so that the energy originally emitted to the environment is recovered and utilized; and the inner wall of the shield body is coated with the metal layer with high reflectivity, so that the capability for reflecting energy of the shield body is enhanced.
Description
Technical field
The utility model relates to a kind of gas cooker energy saving cover, belongs to kitchen range associate member technical field.
Background technology
The consuming excessively of the energy, irrational utilization, a large amount of conspicuous consumption and to cause many-sided the pollution be the very severe problem that China faces in recent decades.The use of natural gas and these fossil fuels of liquefied gas is popularized in China's large tracts of land, and various gas-cookers also grow up thereupon, but up to the present people are still carrying out unremitting effort for the thermal efficiency that improves gas-cooker.Although various modified gas-cookers occurred, but can not accomplish that the thermal efficiency is not high, not only can cause the waste of resource, and can bring various pollutions to the making full use of of fuel gas calorie.Based on above variety of issue, we have proposed the transformation once again to gas-cooker, and purpose is to realize the optimum utilization of fuel gas calorie and reduce and pollute.
The gas burner of China mainly is divided at present: single hole kitchen range, injecting type kitchen range, swirl flame formula kitchen range, plane net cellular type kitchen range and infrared kitchen range.For its advantage of monotrysian type kitchen range is that local heat speed is fast, and but heat is concentrated be comparatively serious for the damage of pot and stove, and the bottom of a pan is local to be damaged easily.Injecting type kitchen range and swirl flame formula kitchen range are comparatively traditional kitchen range types, and heating surface (area) (HS is big, and heat distributes comparatively serious.Plane net cellular type kitchen range is a kind of kitchen range type that is applicable to the even heating of large tracts of land, and fuel gas buring is insufficient, and it is black to be easy to generate pot, and waste and pollution are comparatively serious.The infrared type kitchen range then is a kind of up-to-date type, utilizes the heat of fuel gas buring that wire is heated, thereby the emission infrared ray heats object.All household gas range combustion flames all mainly conduct heat to cooker with the mode of radiation and convection current; Yet; There is quite a few heat to be lost in the surrounding environment with the mode of radiation and goes through the gap between kitchen range main body and the cooker, thereby, a large amount of wastes of heat caused.
The utility model content
The utility model technical problem to be solved is to provide a kind of gas cooker energy saving cover that can improve heat utilization ratio greatly.
The technical scheme of the utility model is following: a kind of gas cooker energy saving cover; Comprise cover body; Said cover body is the upper diameter processed by the carbon steel plate truncated cone-shaped cover greater than lower diameter; The top of said cover body is furnished with at least four foot supports, is coated with one deck has high reflectance to energy metal level on the inwall of said cover body.
Adopt technique scheme, the bottom of cover body directly is seated on the kitchen range, and cooker then is placed on the foot support.The energy part that burning produces directly heats the cooker bottom; Remainder then arrives the bottom of cooker through the annular sidewall reflection of cover body; Thereby the energy that will be lost to originally in the environment is recycled; Plating one deck has the metal level of high reflectance on the inwall of cover body, strengthens the ability of cover body reflected energy.
In technique scheme: the wall thickness of said cover body is 2-3mm.
In technique scheme, the top of said cover body is furnished with four foot supports, and the distance between per two foot supports equates.
In technique scheme: adopt the transition of rounding arc between the top of the sidewall of said cover body and its end face cover mouth, this chamfering circular arc
RBe 17mm.This arch section plays the backflow effect to combustion product gases, and making does not have the combustion gas of after-flame and high-temperature flue gas to carry out burning once more behind the premix, simultaneously the carbon black that produces in the combustion process is sent back to through flow disturbance it is fully burnt, and avoids the pollution to environment.
In technique scheme: the metal level that energy is had a high reflectance on the inwall of said cover body is silver coating or zinc coat.Silver and zinc have the ability of good reflected energy, strengthen the albedo of cover body annular sidewall to energy.
Beneficial effect: the utility model is reasonable in design, enforcement is easy, low cost of manufacture, can improve heat utilization ratio greatly, saves energy, and its thermal efficiency is compared now common gas-cooker and improved 5%-10%.
