Summary of the invention

For overcome traditional large stove and native heating installation arcola technical with function on deficiency, the present invention provides a kind of multifunctional civil little hot-blast stove, this stove when culinary art firepower violent, fuel saving, and can control the duration and degree of heating; When heating, can need not frequently in pot, to add water, the situation that pot is burnt out can not occur; Heating belongs to the hot blast heating, need not worry the freezing heating system of meeting; In addition, the heating function of this stove and cooking function can be changed each other.

The technical solution adopted for the present invention to solve the technical problems is:

Be air-cooled interlayer between combustion chamber inner bag and the shell, have additional diaphragm plate in the air-cooled interlayer, can lead the direction of heat radiation wind, make heat radiation more thorough; Low side at air-cooled interlayer has cooling fan, air-cooled interlayer high-end heat radiation wind air outlet is arranged.

Use two combustion chambers up and down, use the bottom combustion chamber during heating, can guarantee that burning is more abundant, use the top layer combustion chamber during culinary art, can guarantee enough flame impingement thes bottom of a pan, make the temperature of cooking stove more concentrated; Use the cumulative mouth to connect combustion chamber, upper strata and cooking stove, make firepower more concentrated; Adjustment cooking stove outlet flue smoke barrier can effectively be controlled the duration and degree of heating of culinary art; Be two circles annular baffles jaggy between the cooking stove and the bottom of a pan, prolong high-temperature flue gas, improve the effective rate of utilization of fuel in the residence time of cooking stove; The smoke barrier of when being main with heating, opening the second combustion chamber outlet flue is closed cooking stove outlet flue smoke barrier simultaneously and just can be need not frequently in frying pan, to have added water; Use the part of the heat radiation wind in the air-cooled interlayer can realize the hot blast combustion aid function as heat radiation wind, it is more abundant to burn.

The cooking stove outlet flue and the second combustion chamber outlet flue can link together through a smoke structure, get into the anti-flue of a kang of fire.

The invention has the beneficial effects as follows: can realize multifunctional application.The heating aspect, enough effective endotherm areas, desirable heat transfer type, the thermal efficiency is high; Use independently combustion chamber during cooking, use the cumulative mouth and make temperature more concentrated; Adjustment cooking stove outlet flue smoke barrier can effectively be controlled the duration and degree of heating of culinary art; The hot blast heating reduces the investment cost of heating system without radiator.
