Description

Multifunctional household hot-brow stove or range

The utility model belongs to home furnace, be specifically related to a kind of except that cooking with, the cooking stove of heat energy such as heating hot blast, oven dry or cooking food etc. can also be provided simultaneously.

In the modern life, along with China's culture, improving constantly of material life, many urban and rural residents are for improving family life living conditions and environment, cooking stove was carried out various transformations, obtained effect preferably, modal is native heater unit with various Natural Circulation, yet, these native heating equipment ubiquities consume energy big, seriously polluted, circulation bad difficult satisfy simultaneously cooking, two kinds of needs of heating, and mounting cost height, engineering are big, and particularly two-layer above building heating system installation difficulty is bigger.

The purpose of this utility model task provides a kind of home furnace that can satisfy needs such as cooking, heating or oven dry cooking food simultaneously, and this cooking stove small investment, power consumption is low, the thermal efficiency is high, pollution is light, need not facilities such as necessary metal tubes of other native heating equipment and radiator.

This cooking stove is made up of burner hearth, fire grate, dreg chamber, flame-gathering cover, chimney, hot blast generation systems, coal mechanism and the plug of banking up a fire, this burner hearth is taper type, inner surface scribbles ceramic refractory coating, its bottom is provided with the dreg chamber of band closing door, flame-gathering cover is established on the top, has several drawing fires holes and be communicated with chimney on the wall of flame-gathering cover; This fire grate is installed between burner hearth and the dreg chamber, penetrate the shape fire bars and the annular furnace bar is cast as snail like by the many width of cloth, and its protruding snail center deflection charge door on one side, establishes several bellmouths and lead to burner hearth for an enough incoming air area being provided, can being staggered on the fire bars of center; Fire door between flame-gathering cover and burner hearth is the conical surface, and the conical surface is provided with several oblique exhausting fire grooves, and it can form the pyrotechnics from burner hearth strong rotation turbulent flow, and bag is carried out in the kitchen range bottom, carries out large-area turbulent heat exchange, makes full use of heat energy; This hot blast generation systems is at burner hearth, the interlayer chamber of the outer periphery intercommunication of flame-gathering cover and chimney, double end or multi-head spiral blade are housed on the endonexine wall of chamber constitute spiral duct, heated air is entered in the hot blast generation systems, heat in limit and the burner hearth in heat and the chimney carries out sufficient heat exchange, the edge spiral duct rises, and forms a kind of rotation turbulent flow of growing distance and discharges out of the furnace; On bottom, the interlayer chamber circumference of this burner hearth periphery, have the air inlet of 4-8 and helical blade tangential, on the top, interlayer chamber of chimney periphery then fully opening as exhaust outlet, the coal mechanism of this stove is the spiral coal feeder, it comprises sleeve, the twin-feed spiral bar, crank, add coal bunker and bucket cover, this sleeve is worn outside stove to inboard wall of burner hearth, twin-feed spiral is installed in the sleeve, its tail end is established crank control helical rotation, adding coal bunker is located on the sleeve tail end, and there is bucket cover to seal, during coal, open bucket cover, in adding coal bunker, add half water coal, shake crank, twin-feed spiral is about to half water coal equably, continuously send into burner hearth, the secondary air mouth of this stove has 3-6, keep at a certain distance away from the stove periphery by ajutage and to wear to the burner hearth upper oral part, secondary wind directly is provided, and the spiral coal feeder also can be used as complementary secondary air mouth after stopping coal, its using method is: the coal in the sleeve is all drained, open bucket cover, secondary wind enters helical duct from adding coal bunker, and rotation advances in the burner hearth, enough air are provided in stove, this plug of banking up a fire inserts the usefulness of banking up a fire in the fire door in non-cooking with when fire, and it is by interior cover, heating resisting metal collar and drop handle composition, cover is tubular in it, outer surface scribbles ceramic refractory coating, the periphery suitable for reading of cover in the metal collar is fastened in, and its outer surface is the conical surface coupling of funnel-form and fire door and coincide, periphery has several vertical fire-through grooves and ring-type fire-through groove under its funnel, they all with the intercommunication of fire door oblique exhausting fire groove, in drop handle is fixedly connected on the cover top, for proposing the plug use of banking up a fire.When the plug of originally banking up a fire was inserted fire door, the burning in the burner hearth was restricted, and heat is forced to hearth wall and moves outward, continued to the chamber heat supply of hot blast interlayer, and the heat after guaranteeing to bank up a fire is mainly used in the generation hot-air.

The using method and the course of work of this stove are: light a fire by general stove, guaranteeing under the prerequisite of not putting out a fire, by coal mechanism refuelling in the stove make stove fire burn prosperous after, can add and mix the wet coal of water and be laid on the burning bed, after treating that fuel fills up, the surplus coal in the coal spiral is drained, at this moment, down for a wind, make fuel generation CO in the stove by fire grate ₂, at CO ₂Because anoxic is reduced to CO, the water vapour in the wet coal is broken down into H in stove in the uphill process ₂And CO, at this moment because secondary wind inleting tube and coal spiral place infeed a large amount of secondary wind, make to produce strong combustion flame in the stove, except that heat is used in cooking, also have enough hot hot wind supply generation systems.

Below in conjunction with description of drawings detailed structure of the present utility model:

Accompanying drawing 1 is the cross-sectional view of this stove;
