Description

The smokeless frying pan of efficient soaking

Technical field

The present invention relates to cooker field, is a kind of smokeless frying pan of efficient soaking being mainly used in fuel range specifically.

Background technology

Frying pan is the required articles for use in kitchen, but be power consumption Tiger always, since patent (85201777) appearance of domestic Section 1 band muscle sheet, approximate patent text is almost had to occur every year, its common ground is all carry out fin profile design for the pot body of homogenous material, and kitchen frying pan is all based on iron, iron heat conductivility is on the low side, and fin can not play obvious heat absorption conductive effect.Also has the open text of other patent familieses of the same race, its patent No. roughly have following these: 892025433, 912012056, 952345315, 972138161, 972132643, 982461526, 2007200902538, 2007201027384, 2009200467954, 2009200617398, 2010205623858, 2011101867481, 201120430005X, 2012200491584, 2013201998675, 2013207020153, 2014200582845, 2014206198666, 2014206199137, 012474665, 2014103087295, 2008201294483, 982493800, 2011203967761, 2012201943521, 932394701 etc.

Stainless steel aluminum-coating pan (200710010547X), a kind of single face aluminum-plated pot (01251227.3), propose in iron pot external wall compound or electroplate aluminium base, its shortcoming is that aluminium base specific heat capacity with iron-based and thermal deformation differ very large, although the far super iron-based good heat conductivity of aluminium base thermal conductivity, but aluminium base specific heat capacity also substantially exceeds iron-based, be not suitable for the prime being used in heat conduction, can only rear class be used in.

Prior art does not solve the composite problem of band extension fin pot, although be better than with single iron-based fin pot with the pot energy-saving effect of composite, but bare excellent thermal conductor endotherm area is limited, can not high efficiency absorption fire smoke gases heat, even if the aluminum alloy fin pot thermal efficiency that market occurs is even better, but is still not suitable for the frying pan of dry combustion method situation.

Always iron-based pot is used for the bowl of cooking in the world, iron pan cooking is also generally acknowledged secure unique, health, but iron pan thermal conductivity is relatively on the low side, specific heat capacity is also lower, therefore not only power consumption, high temperature gather the bottom of a pan, and relatively easy rapid heating and cooling, add that the chemistry of iron is active, easier because of localized hyperthermia static state link with food molecule, if the material adopting heat conductivility superior a large amount of, its scarcity of resources, price are also high, therefore must solve the problem by technological means.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides and a kind of irony inwall frying pan be significantly improved the thermal efficiency, overcoming the uneven smokeless frying pan of efficient soaking of irony inwall in-plane heat conduction.

The technical solution adopted for the present invention to solve the technical problems is: frying pan by iron or ferrous alloy, heat conductivility is better than iron or ferrous alloy, fin etc. form, extension fin is provided with bottom the frying pan outer wall of iron or ferrous alloy, for expanding the absorbing surface of high-temperature flue gas heat energy, outer wall of wall and extension fin surface are covered with the material that heat conductivility is better than iron or ferrous alloy, for expanding the heat transfer face with even pot inwall.

The technology that described outer wall of wall and the laminating heat conductivility of extension fin surface are better than iron or iron comprises plating or coating.

Described extension fin comprises integrative-structure with the syndeton between pot bulk material or welds or compound.

The material that described heat conductivility is better than iron or iron-based also comprises or sludge proof material more corrosion-resistant than iron.

Described extension fin is arbitrary shape, is arranged as arbitrary shape between fin and fin.

Described outer wall of wall and heat conductivility are better than the laminating joining place surface of iron or iron, also adopt the antirust slip-off preventing technology comprising enamel or japanning or welding or plating.

Be provided with a pot eaves near the pot edge place of described frying pan outer wall or pot edge, the oil stain flowed down when preventing from unloading dish is accumulated in outer wall of wall affects heat transfer.

Described laminating be better than iron or iron at outer wall of wall extends and covers a pot eaves place.

It is described that than iron, more corrosion-resistant or sludge proof material also comprises copper alloy, nickel alloy, evanohm, aluminium alloy, magnesium alloy.

As everyone knows, determine that heat exchanger heat conductivility key factor is heat exchange method, material, area.Frying pan is exactly the function utilizing heat exchange principle to reach food and thermal source to isolate and heat, the fin that frying pan increases various shape is exactly the heat-conducting area expanding heat exchanger, but consider the discharged nitrous oxides problem of fire smoke gases, adapt to the unsuitable complexity of fin shape of gas-cooker and affect flue gas laminar flow, otherwise flue gas also can be walked around bend and take a shortcut and do not have the effect of fin, and fin is good close to radiate.

Iron cooking pot is generally acknowledged healthy and safe cooker, its specific heat capacitance is close to fine copper, heat exchanging process temperature loss is little, lower than aluminium, Cryo Fundamentals are reached by high temperature according to heat trnasfer, iron and copper are all suitable as prime high-temperature hot exchange media, but the heat conduction parameter of iron is far below copper, perishable oxidation, plane thermal diffusion thermal resistance are very large, and thinner thickness direction thermal resistance is close to copper, general kitchen range flame high temperature all concentrates on centre, the bottom of a pan, and all the other heat energy having little time to be absorbed by pot are all by absorption of air.It is to sum up the main cause causing iron pan the bottom of a pan local temperature very high, therefore the feature that copper heat conductivility is superior is utilized, after irony superficies cover one deck copper sheet, copper absorption flame high temperature heat rear portion is comprehensive is rapidly diffused into in-plane, another aspect is quick passes to irony from thickness direction, the combining structure that both learn from other's strong points to offset one's weaknesses, the irony inner wall temperature of pot can be caused comparatively even, pot inwall heating curve is more mild, also just not easily sticky pot and very fast overtemperature emit oil smoke to food, the existence that fire smoke gases district has had large area copper, air is nothing like copper heat conductivility, thus copper improves the thermal efficiency.

Resource makes fin relative to the abundanter more cheap ferrous material of copper, while more or less improving heating surface area, the skeleton of outer copper sheet can be used as again, can also reduction copper materials as much as possible (because copper heat conductivility is far above iron, whole fin all uses copper material to be waste), make the flute surfaces between fin and fin also there is copper sheet, form three-dimensional heat exchange structure, improve the thermal efficiency more significantly.

The smokeless frying pan of the efficient soaking of the present invention has the following advantages.

1. have more the significant thermal efficiency than existing frying pan technology, reduce energy consumption.

2. the deficienter high heat conduction of resource, corrosion resistant raw material have greatly been saved.

3. solve the contradictory problems of iron pan health and energy consumption further.

4. in iron pan, wall temperature difference is no longer greatly different large, and food is sticky pot not easily, and edible oil is not easily smoldered.

Certainly, implement arbitrary product of the present invention might not need to reach above-described all advantages simultaneously.

Below in conjunction with drawings and Examples, the smokeless frying pan of the efficient soaking of the present invention is further illustrated.
