Description

Gas combustion range heat accumulation device

Technical field

The present invention relates to a kind of heat collector improving the hot service efficiency of gas-cooker.

Background technology

Society there is various energy focusing stove, as spiral-flow type flame stove, there is infrared reflection burner hearth, cumulative iron furnace thorax, heat reflection pan burner thorax etc., energy-saving cooking stove head there is radiant panel, its combustion heat energy is primarily of radiant energy and convection current heat energy two parts composition, convection current heat energy refers to the heat transfer of burned flame to pot, and radiant energy, then pass through radiant panel, during burning, radiant panel area is large, fire hole is many, fuel gas buring makes burner plate rubescent, therefore be infrared radiation transmission by the thermal energy produced that burns, due to the characteristics of heat transfer of radiation, for heated material, there is very strong penetrability, its heat is easy to heating object and absorbs, the energy of fuel gas buring is made to obtain the most fully and the most effectively utilize, heating object is more effectively made to absorb, greatly reduce " the chemical heat loss " of energy.But also have partial heat do not utilize, as our cooking cook time, you can feel that heat radiation arrives with it you.The second, these energy focusing stoves, although the hot utilization rate that can improve combustion gas, because manufacturing cost, appreciative value can not allow each family throw away used gas-cooker because of it in time, moreover this energy focusing stove also not too adapts to home-use.For above problem, I devises combustion gas amplitude transformer.

Summary of the invention

The first, for the ease of promoting, improve under the condition not changing gas-cooker.Second, in order to the hot utilization rate of efficiency utilization combustion gas, I designs my product from the principle of thermos flask, the transfer mode of heat is primarily of conduction, convection current and radiation three part composition, the transmission of heat is accelerated in my design from this three aspect, scattering and disappearing of intercept heat: 1, in order to prevent heat convection current and radiation and scatter and disappear, I designs an asbestos insulation cover, shape is as pot shape, be placed between pot and stove plate, the position of stove plate to pot is all fenced up, but leave multiple duck eye in bottom, the oxygen be convenient in air enters, the asbestos that asbestos insulation cover skin adopts thermal conductivity very poor, internal layer then againsts the metal of one deck light, reflecting heat is on pot, 2, in order to improve the utilization rate of heat energy, the multilayer electric furnace silk screen that design becomes with electric furnace silk weaving, make first and be discoidly placed on the burner of middle, first with stove frame for support, make a pot shape, fully can contact with pot, its principle is: because the heat exchanger time of fuel gas calorie and pot is short, and the temperature difference of pot and combustion gas not quite, thus advection heat have and be wasted in a large number, make the thermal efficiency low, due to the characteristics of heat transfer of radiation, for heated material, there is very strong penetrability, its heat is easy to heating object and absorbs, we then utilize this two place electric furnace silk screen to absorb not by heat that pot absorbs, be heated to red heat, they pass through radiation, transfer heat to pot, simultaneously because the temperature of these electric furnace silk screens and stove frame is all very high, and with pot close contact, thus they also transfer heat to pot by the mode of conduction, because inciting somebody to action in the past only by convection current transferring heat, change by the thermaltransmission mode of three kinds of forms, the speed that pot is heated up is accelerated greatly, significantly improve the service efficiency of heat.3, by the oxygen that the aperture below heat shield enters, under the lighting of red heat electric furnace heating wire, the gases such as the carbon monoxide of the combustion gas of not burnt and non-complete reaction can be burnt completely at this, release heat, eliminate the pollution of removing air simultaneously.4, owing to making heat almost be absorbed, when we cook, also can not feel extremely hot.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in implementing the utility model is clearly and completely described, circular electric furnace silk screen in Fig. 1, the electric furnace silk screen 11 comprising the circular iron hoop 12 of band pin and integrally combine with iron hoop, it mainly covers at burner, because the heat exchanger time of fuel gas calorie and pot is short, and the temperature difference of pot and combustion gas not quite, thus advection heat have and be wasted in a large number, make the thermal efficiency low; Due to the characteristics of heat transfer of radiation, for heated material, there is very strong penetrability, its heat is easy to heating object and absorbs, and we then utilize electric furnace silk screen to absorb heat, are heated to red heat, they, by radiation, transfer heat to pot, improve the service efficiency of heat.

Fuel gas buring, flame continues up to emit, transferring heat is to pot, also the electric furnace heating wire 22 in Fig. 2 is heated to red heat simultaneously, part heat electric furnace heating wire also passes to pot with infrared radiation, another part heat, because electric furnace heating wire 22 and stove frame 21 are close to pot, heat then passes to pot in the mode of conduction, moreover the aperture 33 below asbestos insulation cover in Fig. 3 constantly has oxygen to enter, and under the lighting of red heat electric furnace heating wire 22, unburned combustion gas and imperfect combustion carbon monoxide is all burnt completely, release heat, eliminate air-polluting gas simultaneously.

Whole circular electric furnace silk screen 1, stove frame electric furnace silk screen 2 all produce high temperature, be dispersed in air to prevent these heats, asbestos insulation cover 3 on the outer mask of pot, asbestos insulation cover 3 comprises the thicker thermal insulation layer 31 suppressed by heat-barrier materials such as asbestos, simultaneously at the attached metal 32 pressing one deck light of thermal insulation layer inner face, play reflecting heat, be also convenient to cleaning when cooking is made dirty at ordinary times simultaneously; Whole process cuts off three kinds of modes of heat trnasfer as far as possible, prevent heat loss, simultaneously in order to allow pot absorb heat as soon as possible, three kinds of modes of our good good utilisation heat trnasfer again, thus the hot utilization rate of combustion gas can also be improved widely, also can improve the temperature of pot simultaneously, people's cooking be cooked and more rapid and better completes.
