Description

The warm dual-purpose coal-saving stove of cooking a meal of umbrella shape outer cover

The utility model relates to a kind of improved coal stove, and particularly a kind of energy is fit to heating, cooking special use or dual-purpose and novel furnace that can improve the heat energy utilization rate and economize on coal.

Existing coal stove all is upright ladle furnace type, such type of furnace only is fit to cooking, as be used for the heating then be not suitable for, first because the excessive height of stove is not suitable for warm pin, second furnace temperature linearly rises and can not be utilized by heating, and most of heat energy is wasted, be the now existing a kind of public pan burner of suitable heating, the pan burner heating can be warmed up pin, but also has routine defective down, the one, warm pin dish is located at the bottom of stove, heat was quite faint when furnace temperature was transmitted to warm pin dish by furnace shell, can not satisfy the temperature required of warm pin fully, and the 2nd, furnace temperature is linearly rising still, and can not be to radiation all around in order to the body heating, most of heat energy is not utilized and is wasted.

Both be fit to warm pin when the utility model provides a kind of heating, and furnace temperature can to around radiation, really satisfy the brand-new type of furnace of body heating's demand.

The utility model is realized as follows: the outer cover that increases a umbrella shape outside the shell of upright ladle furnace type again, the fixedly boiler face of this outer cover top and stove is connected and fixed, fixedly boiler face is different with other type of furnace boiler face for these, its slightly larger in diameter is in body of heater, leave the gap and lead in the outer cover exceeding the body of heater position, outer cover down is umbrella shape and opens, high about 85 millimeters of lower edge apart from ground, make people's foot can stretch into below the outer cover, on fixing boiler face, increase again an adjustable movable boiler face is arranged, movable boiler face and fixedly have certain clearance to lead in the umbrella shape outer cover between the boiler face, have fire-banking plate on the movable boiler face, when stove is used to warm oneself special use, fire-banking plate on the movable boiler face loam cake, fire-banking plate stops furnace temperature and thermal current linearly to rise like this, and can only by movable boiler face and fixedly the gap between the boiler face enter in the umbrella shape outer cover, again from outer cover bottom pass-out, the conduction of so a part of heat energy by fire-banking plate and the movable boiler face radiation that makes progress, part heat energy passes through the conduction of outer cover to radiation all around, part heat energy ejects under outer cover with gas, owing to being umbrella shape, opens outer cover simultaneously, make temperature on the outer cover can reflex on the ground around the body of heater and make the ground heating, foot stretched into below the outer cover when people warmed oneself like this, just can obtain two aspect heat energy up and down, satisfy the needs of warm foot fully, and, then be fit to the demand of other position heating of human body fully to the temperature of upper of furnace body and radiation all around.This shows when this stove is used for warming stove, can not only satisfy the temperature requirements of partes corporis humani position fully, and can improve the heat energy utilization rate greatly.In addition, because body of heater has increased outer cover outward and hot gas conducts in outer cover, furnace temperature is greatly improved, can improve the burn-off rate of coal, again because of furnace temperature and thermal current can not rise by straight line, and the thermal current flow velocity is slowed down, the flow velocity burning velocity that can make coal that slows down is slowed down greatly, so the type of furnace and the heating of other type of furnace mutually this, the heat energy utilization rate can improve 50% and can economize on coal more than 30% again.

Another advantage of the present utility model is to warm up the dual-purpose of cooking a meal, as long as remove fire-banking plate during if any the cooking task, cooking utensils are placed on the movable boiler face, at this moment main heat is promptly accepted to be used for cooking by cooking utensils, waste heat is promptly along with gas descends discharge and is used for heating from the umbrella shape outer cover, at this moment the heat energy utilization rate of stove has reached the top, can play the dual-purpose special-effect of a stove, and this is well-adapted in scarce coal area.

The big advantage of another of this type of furnace is, need not warm oneself season or when being exclusively used in kitchener, need only regulate between boiler face and the boiler face, the gap between boiler face and the cooker just can do the cooking special use, and can improve the thermal efficiency and economize on coal than other type of furnace.Though the heat energy utilization mode was the same with other type of furnace when principle was this stove cooking, but because this stove has an outer cover to equal to increase one deck heat-insulation layer to stove, heat energy dissipation is reduced, furnace temperature is corresponding to be improved, minim gap between two boiler faces has become the passage of secondary air at this moment simultaneously, there is hot gas to enter burner hearth and helps burning, can be improved so compare other type of furnace thermal efficiency, so can economize on coal about 20%.

Below with reference to drawings and Examples this stove is further described.

Fig. 1 is a kind of concrete structure profile of this stove.

Fig. 2 is the fixedly vertical view of boiler face of Fig. 1 (3).

Shell (1) with reference to a vertical barrel-shaped body of heater of Fig. 1 has additional a umbrella shape outer cover (2) in its periphery, outer cover (2) top edge is connected with fixing boiler face (3), and fixedly boiler face (3) leaves gap (6) and leads in the outer cover.Fixedly being cast with this double wedge of several high about 3 millimeters double wedges (not drawing among this double wedge figure) on the boiler face (3) evenly is spaced around boiler face, fixedly be that the movable boiler face of movable boiler face (4) (4) one side is smooth smooth plane above the boiler face (3), another side is cast with a plurality of double wedges (not drawing among this double wedge figure), high about 15 millimeters of this double wedge, and around boiler face, evenly be spaced by being radial around the middle mind-set.Be provided with a fire-banking plate (5) again on the movable boiler face.Stove is used for heating or warms up when cooking a meal dual-purpose, movable boiler face (4) has one of double wedge to face down, the plane up, at this moment the double wedge on the movable boiler face (4) makes fixedly high about 15 millimeters gaps between the boiler face and movable boiler face, cover fire-banking plate or put cooking utensils, all can force furnace temperature and thermal current to enter in the outer cover by the gap between two boiler faces.And in summer or when being exclusively used in kitchener, movable boiler face need only be turned over, make it to flat down the flank of tooth up, at this moment movable boiler face and fixedly supporting by the double wedge on the fixing boiler face between the boiler face, its gap is varied down to about 3 millimeters, and movable boiler face double wedge up, make high about 15 mm clearance are arranged between cooker on the boiler face and the boiler face, thermal current promptly rises from the gap between movable boiler face and the cooker in the stove, its heat energy utilization is identical with other type of furnace cooking work, movable boiler face and fixedly the minim gap between the boiler face then become the air channel of secondary air.
