Abstract

The utility model provides an energy saving pot which uses a briquette stove for cooking and is a kitchen utensil with a bigger improvement. The utility model is characterized in that radiating type heat gathering pieces which have different length are evenly and symmetrically arranged in a circle which uses the center of the bottom of a pot as a center of circle and has a diameter little smaller than the diameter of a stove opening, the radiating type heat gathering pieces are directly extended into the stove opening, the peripheries of the radiating type heat gathering pieces are evenly and symmetrically provided with impeller type heat gathering pieces with definite height, two kinds of heat gathering pieces have no contact, and then the radiating heating surface and the convection heating surface of the pot bottom are enlarged. The utility model has the advantages of novel and reasonable design and simple structure, the utility model can save 20%-30% of cooking time indicated by experiments, and the utility model is an ideal energy saving pot using a briquette pot for cooking.

Description

The energy-conservation pot of coal dust ball stove

The utility model provides a kind of energy-conservation pot that utilizes coal dust ball stove to cook, and is a kind of bigger improved kitchen utensils that have.

In present technology, the coal dust ball stove that uses in the life is made pot for cooking rice, and its bottom surface, the bottom of a pan all is flat basically, utilizes this flat coal dust ball stove to make pot for cooking rice and cooks, if the bottom of a pan is too near from coal briquette, then needs coal briquette height (at fire door), and fire is not prosperous like this; The bottom of a pan is too far away from coal briquette, and coal briquette is at next segment distance of fire door, though the fire of coal briquette is more prosperous, because the radiation heating-surface and the convection heating surface of pot are all very little, so the utilization rate of heat is lower.

The purpose of this utility model is to provide a kind of big improved cook pot between the energy-and time-economizing of coal dust ball stove that utilizes that has for overcoming above-mentioned shortcoming.

The purpose of this utility model is achieved in that on the bottom of a pan of cooking, with center, the bottom of a pan is in the circle in the center of circle, some radiant type heat build-up sheets evenly are set, but the concentrically ringed radius in radiant type heat build-up sheet outer end and its coal dust ball stove port radius match and merge suit in it, on the corresponding position, outer end of radiant type heat build-up sheet, be provided with vane type heat build-up sheet, the tangent line angle of its inner tangent line and place, radiant type heat build-up sheet outer end circle is 40 °-70 °, and the two does not join, to increase the radiation heating-surface and the convection heating surface in the bottom of a pan, improve the utilization rate of heat in the heat transfer process.

The utility model has the advantages that: 1, because only in the former the bottom of a pan some radiant type heat build-up sheets and vane type heat build-up sheet are set, it does not promptly influence the burning of coal briquette, does not influence exhaust gas discharging again; 2, rationally novel in design, simple in structure, easily manufactured, obvious energy conservation experimental results show that and can save 20%-30% of the time of cooking.

Description of drawings:

Fig. 1 is the main part figure in the energy-conservation pot of the coal dust ball stove the bottom of a pan.

Fig. 2 is the annex map of radiant type heat build-up sheet (2), (3), (4) and vane type heat build-up sheet (5).

Fig. 3 is the cross section of heat build-up sheet.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.

This utility model is that two kinds of shapes radiant type heat build-up

sheet

2,3,4 vane type heat build-up sheets 5 different with effect are being set on pan bottom 1.Broken circle among Fig. 1 is to be the circle in the center of circle with center, the bottom of a pan, 3 kinds of radiant type heat build-

up sheets

2,3,4 that the length differing heights is identical are being set in broken circle, the outer end is all on broken circle, more smaller than furnace port diameter, in the interlaced broken circle that is distributed on the bottom of a pan of 3 kinds of heat build-up sheets, directly reach and absorb heat in the fire door.Uniform vane type heat build-up sheet 5 outside broken circle, its the inner is on broken circle, but do not join with heat build-up

sheet

2,3,4, the angle of inner tangent line and broken circle tangential direction is between 40 °-70 °, highly be lower than heat build-up

sheet

2,3,4, and outside more highly more little, there is certain distance its outer, the outer end distance the bottom of a pan, and its effect is to continue to absorb heat.

This utility model is gone owing to radiant type heat build-up

sheet

2,3,4 can directly reach in the fire door, coal briquette from burning is nearer, be because of the thermal conductivity of metal thermal conductivity so on the one hand much larger than gas, accelerated heat conducting speed, increase the radiation heating-surface and the convection heating surface in the bottom of a pan on the other hand, enlarged the absorption area of heat.Heat build-up sheet (5) is in the periphery of dotted line, and its effect continues to absorb beyond fire door in the flame and the heat in the waste gas on the one hand, contact with fire door on the other hand, the supporting-point that is pot, and waste gas after burning is discharged between two heat build-up sheets.

Claims

1, the energy-conservation pot of the coal dust ball stove that provides of the utility model, its primary structure feature is that radiant type heat build-up sheet (2), (3), (4) that the short not equal altitude of some block lengths equates are set in the circle that is the center of circle equably with center, the bottom of a pan, and its outer end is being provided with vane type heat build-up sheet (5) on heat build-up sheet (2), (3), (4) outer end opposite position on a concentric circles.

2, according to the energy-conservation pot of the coal dust ball stove of claim 1, it is characterized in that being that radiant type heat build-up sheet (2), (3), the concentrically ringed diameter in (4) place, outer end match with mouthful diameter of coal dust ball stove, but and suit in it.

3, the energy-conservation pot of coal dust ball stove according to claim 1 it is characterized in that the inner tangent line of vane type heat build-up sheet (5) and the tangent line angle that justify at radiant type heat build-up sheet (2), (3), (4) place, outer end are 40 °-70 °, and the two does not join.
