Description

Energy-conservation cooking stove

Technical field

The utility model relates to a kind of energy-conservation cooking stove, belongs to the firing equipment technology.

Background technology

The energy-conservation cooking stove that the utility model is related, mainly be applicable to such as stew soup, following and cooking aspects, kitchen such as dumpling, steamed sweet bun.

People are familiar with for the structure and the mode of heating of existing cooking stove.The succession mode of heating of cooking stove for a long time all is bowl directly to be put be held in the suitable for reading of gas-cooker coal fired stove oil range and carry out.Undoubtedly, it is very low that this mode of heating exists the heat effective rate of utilization, deficiencies such as ambient influnence difference.This also is that people are familiar with.

Summary of the invention

The purpose of this utility model is to provide a kind of energy-conservation cooking stove with energy-conservation effect, overcoming the deficiency of prior art, for economic society is cut down expenses and saved the energy.

The utility model realizes that the technical scheme of its purpose is, a kind of energy-conservation cooking stove, and the bowl that has grate and connect with grate, its improvement is: also have heat exchange lasso and at least 1 smokejack; The heat exchange lasso is made up of inside race that is located at the bowl intracavity bottom respectively and outer collar; Inside race and outer collar respectively with bowl diapire fixed connection, between inside race and outer collar, be provided with the exhaust gases passes that passes through apart from Gong the flame that constituted and hot-air by between the two, the lower end of exhaust gases passes communicates with the external world; Upper end at exhaust gases passes is provided with hush panel; Smokejack is located at the top of exhaust gases passes and connects with exhaust gases passes.

Can understand by above given technical scheme, the utility model is owing to the existence of heat exchange lasso, and the water liquid that is present in the bowl directly contacts with the heat exchange lasso, thereby has effectively enlarged heat exchange area, improve heat utilization ratio, realized its purpose of energy saving.The lab scale result shows, the comparable prior art energy savings 35～40% of the utility model.

The further improvement of the utility model point is:

In exhaust gases passes, be provided with both sides respectively with the heat collecting sheet of interior snare and outer collar fixed connection.Because the existence of heat collecting sheet has further enlarged heat exchange area and energy savings, has also strengthened the bulk strength of bowl simultaneously.Under the condition that does not possess heat collecting sheet, can be on the bowl diapire with respect to the position of exhaust gases passes, offer the hole that several communicate with exhaust gases passes, flame and hot-air that said kitchen range are generated enter exhaust gases passes, can guarantee the bulk strength of bowl again.

Outside at bowl is provided with adiabator layer.Why will establish adiabator layer, its purpose also is energy savings.

Bowl is made up of less than the lower pot body of upper pan body upper pan body and cross-sectional area, and the heat exchange lasso is located at the bottom of lower pot body inner chamber; The upper surface of heat exchange jacket and the bottom surface of upper pan body maintain an equal level.Its purpose is to reduce the distance between outer collar and the lower pot body, and the easier boiling of water liquid that is present between lower pot body and the outer collar is rolled, to help enduring the needs of bone soup and cooking such as following and dumpling, further energy savings.

Be provided with in the bottom of bowl can ccontaining gas-cooker oil range/coal fired stove the combustion chamber; The lower end of said exhaust gases passes communicates with the combustion chamber.Because the existence of combustion chamber, both can avoid the diffusion of flame that said kitchen range generate and hot-air and wasted heat, simultaneously also in order to improve environmental condition.

Characteristics such as after technique scheme was implemented, the energy-saving effect that the utility model had was obvious, and environmental condition is good are conspicuous.

The specific embodiment

By above given accompanying drawing, can understand the technical solution of the utility model.Below in conjunction with the description of accompanying drawing by the specific embodiment, the utility model is described in further detail.

A kind of typical specific embodiment is shown in accompanying

drawing

1,2,3,4,5.A kind of energy-conservation cooking stove, the bowl 2 that has grate 1 and connect with grate 1 also has heat exchange lasso 3 and 1 smokejack 4; Heat exchange lasso 3 is made up of inside race 3-1 that is located at bowl 2 intracavity bottoms respectively and outer collar 3-2; Inside race 3-1 and outer collar 3-2 respectively with bowl 2 diapire 2-3 fixed connections, the lateral wall of the madial wall of inside race 3-1 and outer collar 3-2 all can be heated water liquid and directly contact; Be provided with the exhaust gases passes 5 that passes through apart from Gong the flame that constituted and hot-air by between the two between inside race 3-1 and outer collar 3-2, the lower end of exhaust gases passes 5 communicates with the external world; Be provided with hush panel 3-3 in the upper end of exhaust gases passes 5; Smokejack 4 is located at the top of exhaust gases passes 5 and connects with the upper end of exhaust gases passes 5.In exhaust gases passes 5, be provided with both sides respectively with the heat collecting sheet 6 of interior snare 3-1 and outer collar 3-2 fixed connection.Be provided with adiabator layer 7 in the outside of bowl 2.Bowl 2 is made up of upper pan body 2-1 and the cross-sectional area lower pot body 2-2 less than upper pan body 2-1, and the cross section of upper pan body 2-1 is square, and the cross section of lower pot body 2-2 is rounded; Heat exchange lasso 3 is located at the bottom of lower pot body 2-2 inner chamber; The bottom surface of the upper surface of heat exchange jacket 3 and upper pan body 2-1 maintains an equal level.Be provided with in the bottom of bowl 2 can ccontaining gas-cooker oil range coal fired stove combustion chamber 8; The lower end of said exhaust gases passes 5 and combustion chamber 8 connect.Its bowl 2 and heat exchange lasso 3 all are cylindric.
