Abstract

The utility model relates to an energy saving pot. In the utility model, the bottom of the outer side of a common pot is provided with a plurality of cycles of annular fins, the annular fins are provided with a quantity of smoke gas flowing holes on the combining positions with the pot bottom, the peripheries of the fins are also provided with an annular heat gathering piece for collecting smoke gas, the annular heat gathering piece is provided with a smoke outlet, and circulation holes on all the annular fins are crossedly ranged for increasing the zigzag of the flow of smoke gas. Because the annular fins can expand a heat changing surface and intensify heat transmission for causing more smoke gas heat quantity to be absorbed by a pot body, and the utility model has the advantages of fuel saving, time saving and high speed of heating. When the utility model is widely spread, the utility model can have an obvious energy saving effect.

Description

Energy saving pot

The utility model relates to home-use cooking pot and stove.

The bottom of a pan, the outside of existing cooker all is smooth, and heating surface area is less, and heat-transfer intensity is lower, is unfavorable for the heat in the cooking stove is imported in the pot.In addition, the hot flue gas that flame produces skims over very soon along the bottom of a pan, and its heat is fully utilized far away and promptly enters flue or dissipation.Therefore the heat utilization ratio of common pot and stove is very low, and less than 40% not only causes waste of fuel, and prolonged heat time heating time.

The purpose of this utility model is the above-mentioned shortcoming that will overcome existing pot and stove, and a kind of cooking pot and stove of energy augmentation of heat transfer is provided, thereby improves the utilization rate of calory burning.

Solution of the present utility model is: the exterior bottom at the pot body is provided with some annular fins, has some flue gas openings with junction, the bottom of a pan on the fin; And be provided with annular heat build-up sheet in the periphery of annular fin, have venthole on this heat build-up sheet.

Describe the embodiment of utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the longitudinal sectional view of energy-conservation pot.

Fig. 2 is the upward view of Fig. 1.

Fig. 3 is annular fin and three-dimensional diagrammatic sketch after separate in the bottom of a pan.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, the concentric annular fin 2 of two circles that is provided with of the part that contacts with flame in the bottom of a pan.On each fin, have many flue gas openings 3 with junction, the bottom of a pan.In the periphery of fin 2 are annular heat build-up sheets 5, and smokeless air-flow through hole on it has only a venthole 6.Annular heat build-up sheet 5 works to compile flue gas, can prevent flue gas dissipation.Flue gas after compiling is flowed out by a venthole 6, and this outlet also can be aimed at back pot flue.The number of turns of annular fin is generally 1～4 circle, decides on the concrete condition of pot and burning.Annular fin and heat build-up sheet can join together with the also available welding method of forging type cast solid with connecting of the bottom of a pan.

During manufacturing, the opening 3 on several annular fins preferably adopts wrong row's form, to increase the complications of flow of flue gas, prolongs flame, flue gas heat time heating time to the bottom of a pan and fin, and the heat of flue gas is fully absorbed by pot body 1.

Fig. 3 is single annular fin and three-dimensional diagrammatic sketch after separate in the bottom of a pan.

This energy saving pot adopts annular fin expansion heat-transfer surface and enhanced heat exchange, makes the heat of flue gas more by the pot bulk absorption, so fuel savings, saves time, and firing rate is fast. If promote, will have obvious energy-saving effect.

Claims

1, a kind of energy-conservation pot comprises a pot body (1), it is characterized in that in pot body (1) exterior bottom the annular fin of some circles (2) being set, and has some flue gas openings (3) with junction, the bottom of a pan on annular fin; And be provided with annular heat build-up sheet (5) in the periphery of annular fin, have venthole (6) on this heat build-up sheet.

2, energy-conservation pot as claimed in claim 1 is characterized in that the flue gas opening (3) on said each annular fin (2) adopts wrong row's form, to increase the complications of flow of flue gas.
