Description

A kind of energy-saving cooking
The utility model belongs to domestic stove, and it is good to be specifically related to a kind of fuel performance, and fuel utilizes scope wide, saves the energy, the high-efficiency cooking cooking stove that environmental pollution is little.
Also use the vast rural area of China of the main fuel that traditional fuels such as crop stalk, coal cook as lighting a fire more at large, also continue to use the cooking stove that old-fashioned brick clay is built by laying bricks or stones always.The disadvantage of this cooking stove is that the burning of fuel is insufficient, and the utilization rate of heat energy is low, and is bigger to the pollution of environment.Also easily cause the plague of rats, insect pest for native kitchen range, very unhygienic.And old-fashioned cooking stove generally can only heat pot body part (firepower mostly concentrates on the bottom of a pan district), and its heat exchange area is little, and the heat energy utilization rate is low.Though people have also carried out structural transformation or improvement to old-fashioned cooking stove, end is unsatisfactory because of its heat exchange method, and is difficult to reach the raising thermal efficiency, the purpose of energy savings.The tradition cooking stove can produce a large amount of flue dust and pernicious gas because fuel combustion is incomplete during burning, causes the pollution of environment.Current era, energy shortage, imbalance between supply and demand becomes increasingly conspicuous, people are very urgent to the demand of energy-conserving product in productive life, and the utility model people is through concentrating on studies for many years for this reason, developed a kind of simple in structure, heat exchange method is reasonable, save the energy, the novel energy-conserving cooking stove that environmental pollution is little, through evidence, its energy-saving and environmental protection are respond well.
It is a kind of simple in structure, with low cost that the purpose of this utility model is to provide, and has good burning performance, and fuel utilizes scope wide, saves the energy, the energy-saving cooking that environmental pollution is little.
The utility model is achieved in that it comprises several parts compositions of stove, air intake ash disposal cavity, the kitchen range top and support.Air intake ash disposal cavity is provided with air inlet and damper, and its bottom is connected with support.The annular secondary air passage of the light a coal fire with firewood circle and the outside thereof of uniform passage constitutes secondary burning-assist burner hearth jointly on the circumference that the stove middle part is provided with, and the bottom of stove is a fire grate.Circle one side opening of lighting a coal fire with firewood is communicated with the kitchen range door through passage.The arranged outside packing layer of secondary air passage, there is the return air channel of an annular in the outside of packing layer, its outer heat-insulation layer that is provided with.The top of packing layer and burner hearth adapts with pot body bottom surface, constitutes circular arc heat exchange guide face between the two.A side relative with fire door is provided with flue, and the bottom of flue and return air channel is by channel connection, flue arranged outside heat-insulation layer, and the middle part is provided with the dedusting flow deflector, and the bottom of flue is provided with the dedusting hole, and top connects smoke exhaust pipe.
Because the utility model has adopted the flow-guiding type heat exchange method, has not only simplified the structure of cooking stove, and has improved the heat exchanger effectiveness of cooking stove; The design of secondary burning-assist chamber structure has improved combustion conditions greatly, has improved the fuel thermal energy utilization rate; The flue flow deflector can reduce the discharge capacity of flue dust effectively, reduces the pollution to environment.The utility model is simple in structure, and cost of manufacture is cheap, is a kind of kitchener kitchen range of economical and practical, energy-efficient, environment-friendly type.
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but the utility model is not limited to shown in the accompanying drawing.
Fig. 1 partly cuts open front view for the utility model one embodiment's;
Fig. 2 is the vertical view of Fig. 1 (not having pot body state);
Fig. 3 is that the AA of Fig. 2 is to view.
As shown in the figure, the utility model comprises stove 1, air intake ash disposal cavity 2, the kitchen range top 11 and support more than 13 parts composition.Air intake ash disposal cavity 2 is provided with air inlet 7 and damper 8, and its bottom is connected with support 13.The light a coal fire with firewood circle 6 and the outside annular secondary air passage 14 common formation secondary burning-assist burner hearths 21 thereof of uniform passage on the circumference that stove 1 middle part is provided with, stove 1 bottom is a fire grate 10.Circle 6 one side openings of lighting a coal fire with firewood are communicated with kitchen range door 3 through passage 4.The arranged outside packing layer 15 of secondary air passage 14.There is the return air channel 9 of an annular in the outside of packing layer 15, its arranged outside heat-insulation layer 18.Packing layer 15 adapts with pot body 20 bottom surfaces with the top of burner hearth 21, constitutes circular arc heat exchange guide face 19 between the two.A side relative with fire door 3 is provided with flue 17, and flue 17 is communicated with by passage 23 with the bottom of return air channel 9, flue 17 arranged outside heat-insulation layers, and the middle part is provided with dedusting flow deflector 16, and the bottom of flue 17 is provided with dedusting hole 24, and top connects smoke exhaust pipe 12.
Kitchen range door 3 is provided with peep hole 22 and door shelves 5.Observe escutcheon and be the pendulum-type structure, easy and simple to handle.Door shelves 5 are brake clip formula structure.
Damper 8 on the air intake ash disposal cavity 2 can be the chute-type structure, also can be the pendulum-type structure, all can realize the purpose of this utility model.
The fire holding cycle 6 of burner hearth and secondary air passage 14 can be directly affixed with stove 1 be whole, also can be processed into the split combiner, with stove 1 combination installation, can realize the purpose of this utility model equally.
The schematic structure of flow deflector 16 in the flue 17 has been shown among Fig. 3.Flow deflector 16 is the narrow rotary propeller type structure of the wide end of an end, is traditionally arranged to be relative two couple, and staggered form is arranged, and promptly a pair of wide end is downward, and another is downward to narrow end, with the bottom Joint of flue 17.Also can take other forms of arrangement mode, all not influence the realization of the utility model purpose.
Guide face width between pot body 20 bottoms and burner hearth 21 end faces is 0.5-2cm, is preferably 1.0-1.5cm.
Discharge flue 23 is lower than the position of kitchen range door 3, forms the downdraft discharge flue.High-temperature flue gas circulation path in stove prolongs, and heat-insulation layer is further inhaled amount of stored heat, helps the insulation of stove, improves the heat energy utilization rate.
Packing layer, heat-insulation layer can be heat-storage heat preservation materials such as peat, plant ash, slag and rock wool.
Result of the test shows that the energy-saving cooking energy-saving and environmental protection effect of the utility model is remarkable.Can adopt iron coal, wheat straw, dish root, assorted straw, firewood etc. to make fuel.Cooking stove when cold conditions, per 10 kilograms (12-21 ℃) natural well water, 6-8 two pure fuel (as iron coal etc.) 10-13 minute can be boiled; When hot, 5 liang of pure fuel 8 minutes can be boiled.Assorted straw fuel such as wheat straw also only needs 9 liang of fuel, and 14 minutes can be boiled.And visible smoke intensity is very little, almost can't see the smog of discharge, and the pollution of environment is obviously reduced.
Characteristics of the present utility model:
