Abstract

The utility model discloses an energy-saving cooker. The cooker bottom of the energy-saving cooker is formed in the casting mode or in the die stamping mode, a groove which is circled on the cooker bottom and a groove wall plate form a spiral flow guiding groove, and the groove wall plate is provided with a flow baffling blade. The structure can enlarge the heating area as well as extend the time of hot air circling the cooker bottom; the absorbed heat occupies 40% of the total energy of gas fuel, and the heat efficiency can be improved by about 60% as compared with an ordinary cooker. The utility model which has the advantages of energy saving, time saving, simple structure, long service life, etc. Is particularly suitable for heating water, cooking rice, and cooking dishes by taking gas as fuel.

Description

Energy-saving cooker

The utility model relates to the energy-conservation pot of a kind of civilian cooker.It is particularly suitable for being that fuel is heated up water, cooked, using during cooking with gases such as natural gas, coal gas.

Commercially available various pot, its outside, the bottom of a pan all is smooth plane or arc surface, cook with natural gas, flame heat energy is just very fast to external diffusion during cooking, the not enough combustion of natural gas of the heat energy of pot bulk absorption released energy 1/5, make its most of thermal waste.Chinese patent has been announced " a kind of energy saver " (CN2130459Y), its the bottom of a pan is welded with a plurality of annulus or the spirality by the iron bar coiled, though it can increase thermal conduction effect, increase convection heat transfer' heat-transfer by convection and radiant heat transfer, concentrate but stress can occur, so the bottom of a pan of pot body is short service life at welding region.

The purpose of this utility model is intended to overcome above-mentioned shortcoming, and having designed a kind ofly can increase thermal conduction effect, long-lived again energy-conservation pot.

The purpose of this utility model is to realize like this: the groove and the groove wallboard that are cast as one with the bottom of a pan are surrounded on the bottom of a pan, and constitute the spiral stream guidance groove, radially are distributed with the choked flow blade on its groove wallboard.

The purpose of this utility model can also realize like this: the bottom of a pan, plane also can be stamped to form.Inside and outside have the spiral stream guidance groove that the groove that is surrounded on the bottom of a pan and groove wallboard constitute, on the groove wallboard of its outside, the bottom of a pan, radially be distributed with the choked flow blade.

The utility model is compared with commercially available various pots, except that the structure difference of the bottom of a pan, and other structure all similar.Because the bottom of a pan has spiral stream guidance groove and guide vane, both increased heating surface area, prolong the time of thermal current again around the bottom of a pan, the thermal efficiency ratio ordinary pan improves about 60%, energy that this energy-conservation pot is absorbed accounts for 40% of gross energy that gaseous fuel discharges, does a meal required time and only is 2/3 of ordinary pan.The utility model is compared with the bottom of a pan of aforementioned " a kind of energy saver ", and its bottom of a pan is simple in structure, but still can reach same increase thermal conduction effect, again because the bottom of a pan structure adopts casting or punch die to make, so unstressed concentration zones.Therefore, the utlity model has energy-conservation, save time, advantage such as simple in structure, long service life.

Below in conjunction with drawings and Examples this reality there be novel elaborating:

Fig. 1 is structural plan, a bottom of a pan of the present utility model schematic diagram.

Fig. 2 is Fig. 1 arc surfaced the bottom of a pan radial cross-section.

Fig. 3 is Fig. 1 plane the bottom of a pan punching press radial cross-section.

Embodiment one: the pot body of this energy-conservation pot is a circular arc, and its pot caliber size, the bottom of a pan degree of depth are identical with commercially available frying pan, and its bottom of a pan external structure is referring to Fig. 1, Fig. 2.Have the groove 3 and the groove wallboard 1 that are surrounded on the bottom of a pan in outside, the bottom of a pan and constitute the spiral stream guidance groove, the effect that has the current limliting blade 2(current limliting blade 2 that radially distributes on groove wallboard 1 both sides had both hindered distributing fast of hot-fluid, can reinforce a pot body again).The about 1CM of its groove 3 width, the height of groove wallboard 1 is 1/2 of groove 3 width, the height of current limliting blade 2 is 3/4 of a groove wallboard 1.The casting of whole cooker body forms.

Embodiment two: the pot shape of this energy-conservation pot is similar to commercially available all kinds of pot for cooking rice pot bodies.Except that whole cooker bottom structure circular arc is the planar shaped, other structure is all identical with embodiment one.

Embodiment three: the pot shape of this energy-conservation pot is similar to the commercially available all kinds of pots (or kettle) of heating up water, and whole cooker body punch die forms, and its bottom of a pan, plane structure is referring to Fig. 1, Fig. 3.Have the groove 3 and the groove wallboard 1 that are surrounded on the bottom of a pan inside and outside the bottom of a pan and constitute the spiral stream guidance groove, the effect that has the current limliting blade 2(current limliting blade 2 that radially distributes on groove wallboard 1 both sides of outside, the bottom of a pan is same as described above).Its groove 3 width equate highly that with groove wallboard 1 height of choked flow blade 2 is 1/2 of groove wallboard 1 height, and the width of choked flow blade 2 should not surpass 1/2 of ditch groove width.The energy-conservation pot of this structure mainly is the heating that is used for liquid.

Groove width of this energy-conservation pot is according to the decision of pot body material, and the bottom of a pan material and commercially available pot of materials of aluminum, iron, copper are identical, and the spiral stream guidance groove also can be the involute formula.

Claims

1, a kind of energy-conservation pot, it is characterized in that: the groove and the groove wallboard that are cast as one with the bottom of a pan are surrounded on the bottom of a pan and constitute the spiral stream guidance groove, are radially distributed with the choked flow blade in groove wallboard upper edge.

2, energy-conservation pot according to claim 1, it is characterized in that: the bottom of a pan, plane also can be adopted and is stamped to form, and has the groove and the groove wallboard that are surrounded on the bottom of a pan inside and outside it and constitutes the spiral stream guidance groove, is radially distributed with the choked flow blade in the groove wallboard upper edge of pot outside.

3, energy-conservation pot according to claim 1 and 2, it is characterized in that: the spiral stream guidance groove is the involute formula.
