Abstract
The utility model relates to a cooking stove. In the utility model, the inner part of a traditional coal stove is provided with a horseshoe-shaped concave surface hearth bottom used for causing flame to be appressed with a pot bottom and for energy gathering action, and a wind returning trough is arranged between the upper edge and the hearth wall of the horseshoe-shaped concave surface hearth bottom and can generate thermal vortex. The utility model has the advantages of high thermal efficiency, quick ignition, no blower and good effect of energy saving, and the utility model is especially suitable for works, armies and other collective meal institutions.
Description
A kind of kitchener kitchen range, the high cooking stove of particularly a kind of energy-saving efficiency.
The kitchener kitchen range of people's use at present, the thermal efficiency is low, and waste fuel is serious.The big cooking stove that most units use mostly needs with the air blast blowing, so that fuel can fully burn, this will consume considerable electric energy, can not really obtain energy-conservation effect.And because used air blast, it is inhomogeneous to cause iron pan to be heated, and can make iron pan local temperature height, and the phenomenon that often has iron pan to burst occurs.
The purpose of this utility model provides a kind of kitchener kitchen range energy-conservation, that iron pan is heated evenly.
The technical scheme of finishing the utility model task is to make horseshoe-shaped concave surface at the bottom of the burner hearth, makes at the bottom of the horseshoe-shaped concave surface burner hearth and the iron pan bottom surface matches, and the return duct of an annular is arranged between the outer on top and the hearth wall.Return duct and chimney communicate.When making a fire, pyrotechnics is close to the bottom of a pan along concave surface and is entered return duct, produces hot eddy current in return duct, and pyrotechnics stops the long time in return duct, makes pot can obtain more thermal energy fully.
Fig. 1 is the profile of the utility model embodiment.
1 be horseshoe-shaped concave surface burner hearth at the bottom of
2 is return duct
3 are the fiery groove of storage
4 is flue
5 is the coal storage groove
6 is fire door
7 is fire bars
8 is iron pan
9 is ventilating duct
10 is hearth wall
At the bottom of the horseshoe-shaped concave surface burner hearth (1), top is big, and the bottom is little, the front height, and the back is low, and the bore of its size and iron pan is corresponding.The effect of (1) is to make coal be close to the bottom of a pan at the fiery groove burning fire seedling of storage at the bottom of the shape of a hoof concave surface burner hearth, and heat energy is sent to rapidly in the pot, also will play the function of insulation heat build-up.
Return duct is positioned between the upper edge and hearth wall (10) of (1) at the bottom of the shape of a hoof concave surface burner hearth.Return duct at the bottom of the shape of a hoof concave surface burner hearth (1) the outer, top circlewise.Return duct (2) is that beloid, preceding high back is low, is domatic.The anterior wide 5cm of return duct, dark 4cm; The wide 6cm in middle part, dark 5cm; The rear portion is wide and be 8～10cm deeply.Return duct and hearth wall are smooth smooth, so that pyrotechnics is unblocked in burner hearth.When the bottom that pyrotechnics (1) at the bottom of the shape of a hoof concave surface burner hearth is close to iron pan (8) enters return duct, in return duct, produce hot eddy current, make pyrotechnics in return duct, stop the time of growing, make iron pan make full use of the heat energy of pyrotechnics.
Storing up fiery groove (3) is the combustion chamber of fuel.The bottom of storing up fiery groove (3) is fire bars (7).Store up fiery flute length 27cm, wide 18～20cm.
Coal storage groove (5) is the place that stores coal, is positioned between fire door (6) and the fiery groove of storage (3), and size can be held 2500 grams～3000 gram coals and get final product.Be located in the cooking stove in the coal storage groove, can prevent to reduce temperature in the burner hearth because of blow-on door coal repeatedly.
Fire door (6) is the closed fire door of cast iron.The panel top of fire door (6) has an osculum, and glass is housed on the opening, so that observe combustion case; There is the osculum of a 1cm * 8cm below, is convenient to carry out under the situation of not blow-on door the coal operation.
A pyrotechnics part that produces during in storage fiery groove (3) internal combustion when coal flings the bottom of a pan, and a part (1) at the bottom of the shape of a hoof concave surface burner hearth temperature that makes iron pan (8) that rises raises, and enters then in the return duct (2).Pyrotechnics produces hot eddy current in return duct (2), make iron pan (8) obtain more heat.
Coal is supplied with sufficient air in storage fiery groove (2) internal combustion by ventilating duct (9).The coal gas that produces in combustion process is discharged through flue (4).Be placed on earlier in the coal storage groove (5) owing to coal is given, when the needs coal, need do not open fire door and can operate, it carries out under air-proof condition, remains higher temperature in the burner hearth thereby make.
Fig. 2 is a vertical view of the present utility model.
The thermal efficiency of the present utility model reaches 60%, coal saving rate is more than 66%, because without the air blast blowing, energy-conservation more obvious.
The utility model is specially adapted to messes unit of collective.
Claims (3)
1, a kind of shape of a hoof range of returning-air, comprise storage fiery groove [3], flue [4], fire door [6], fire bars [7], ventilating duct [9], it is characterized in that having in the burner hearth [1] at the bottom of the horseshoe-shaped concave surface burner hearth, the return duct [2] of a ring-type is arranged between the upper edge of horseshoe-shaped concave surface furnace bottom [1] and hearth wall [10].
