Description

Civil three-purpose energy-saving hot-air stove

It is that fuel can be used for heat supply water, hot blast and the domestic life energy-conservation three of cooking is used hot-blast stove with the coal that the utility model relates to a kind of.

At present, China all uses in many areas with the indigenous heating stove of coal as the energy, and especially in the north, indigenous heating stove is used to heating and cooks.Indigenous heating stove is formed by hot-water supply with for Rice cooker, and hot-water supply is made up of smoke guiding tube, outer sleeve, the device of Gong cooking by body of heater, stone or metal plate for standing a stove on as a precaution against fire, fire grate, drop-bottom, draw smoke pipe and form.Use indigenous heating stove, the thermal efficiency is low, hot slowly, and water is difficult for being heated and but easily produces and overstocked incrustation scale, and incrustation scale also is difficult to cleaning, and waste heat is not used.

The purpose of this utility model is to provide a kind of thermal efficiency height, be difficult for producing the also cleaning easily of incrustation scale, incrustation scale, simple in structure, be convenient to make, the domestic life energy-conservation three of convenient maintenance uses hot-blast stove.

The purpose of this utility model can reach by following measure.The utility model comprises hot-water supply, hot wind supply and the device of cooking, hot-water supply comprises smoke guiding tube, outer sleeve, cold water hole is arranged on the outer sleeve into and be welded with out the hot-water mouth, hot wind supply and the device of cooking comprise support plate, base plate, the body of heater inner core, the fire grate cushion block, be placed on the fire grate on the fire grate cushion block, stone or metal plate for standing a stove on as a precaution against fire, be placed on the bell on the stone or metal plate for standing a stove on as a precaution against fire, be welded on the dust removing tube on the body of heater inner core, lead smoke pipe, insert the dustproof plate of dust removing tube, its special feature is: hot-water supply also comprises the heat guide fin that is welded on the smoke guiding tube, flange, heat-insulation layer, hot wind supply and the device of cooking also comprise flange, draw the cigarette inner sleeve, be welded on the heat guide fin on the body of heater inner core, outer sleeve, be welded on the air outlet on the outer sleeve, air inlet, the smoke guiding tube of hot-water supply are inserted into and draw outside the cigarette inner sleeve.

The purpose of this utility model can also reach by following measures:

Can there be 4 heat guide fins evenly to be welded on the outer wall of smoke guiding tube, have 8 heat guide fins evenly to be welded on the body of heater inner tank theca.

Drawing the cigarette inner sleeve can also be the quarter bend tube.

Owing to adopt said structure, the utlity model has following advantage: smoke guiding tube, dust removing tube, body of heater inner core, lead the loop that smoke pipe forms and make burning of coal very abundant; The employing of heat guide fin makes water and wind be heated easily, thermal efficiency height; Hot-water supply can be taked the mode of horizontal positioned, and is easy to use, also can take off easily so that clear up incrustation scale; The utility model is simple in structure, is convenient to make and maintenance.

Fig. 1 is a main pseudosection of the present utility model.

Fig. 2 is the utility model hot wind supply, Rice cooker A-A profile.

Fig. 3 is the utility model hot-water supply B-B profile.

Fig. 4 is that the utility model draws the quarter bend tube profile that the cigarette inner sleeve can adopt.

Below in conjunction with accompanying drawing the utility model is further described.

The utility model comprises hot-water supply, hot wind supply and the device of cooking.Hot-water supply comprises to be had into cold water hole ［ 20 ］ and is welded with out hot-water mouth ［ 21 ］ on smoke guiding tube ［ 17 ］, outer sleeve ［ 15 ］, the outer sleeve, evenly be welded with 4 heat guide fins ［ 16 ］ on smoke guiding tube ［ 17 ］ outer wall, be welded with upper flange ［ 18 ］, lower flange ［ 14 ］ between smoke guiding tube ［ 17 ］ and the outer sleeve ［ 15 ］, heat-insulation layer ［ 19 ］ is arranged on the upper flange ［ 18 ］, heat-insulation layer ［ 13 ］ is arranged under the lower flange ［ 14 ］.Hot wind supply and the device of cooking comprise three support plates ［ 1 ］, be welded on the base plate ［ 2 ］ on the support plate ［ 1 ］, be welded on base plate ［ the body of heater inner core ［ 3 ］ on 2, be welded on four the fire grate cushion blocks ［ 5 ］ on the body of heater inner core ［ 3 ］, equally distributed eight heat guide fins ［ 9 ］, lead smoke pipe ［ 10 ］, dust removing tube ［ 4 ］, flange ［ 7 ］, stone or metal plate for standing a stove on as a precaution against fire ［ 11 ］, be placed on the fire grate ［ 6 ］ on the fire grate cushion block ［ 5 ］, be placed on the bell ［ 24 ］ on the stone or metal plate for standing a stove on as a precaution against fire ［ 11 ］, with flange ［ 7 ］, the outer sleeve ［ 8 ］ of stone or metal plate for standing a stove on as a precaution against fire ［ 11 ］ welding, be welded on the air outlet ［ 22 ］ on outer sleeve ［ 8 ］ outer wall, air inlet ［ 25 ］ is welded on and draws cigarette inner sleeve ［ 12 ］ on the stone or metal plate for standing a stove on as a precaution against fire ［ 11 ］.The smoke guiding tube 17 of hot-water supply is inserted into and draws outside the cigarette inner sleeve 12.
