Description

Multi-purpose self-blowing coal stove

The utility model be a kind ofly make meal, warm oneself, have a bath, multi-purpose family expenses life coal stove such as heat supply water, cooking food.It mainly burns honeycomb also can burn coal briquette, briquette or diffusing coal.

At present, the coal stove of selling on the market is of a great variety, and structure is different, but has the following disadvantages:

(1) the slow combustion temperature of getting angry is low, and the thermal efficiency is low, and it is time-consuming to make meal.

(2) adopt coal chimney heat radiation heating, the thermal efficiency low, and price is also high, not only price is higher to adopt the hot-water heating mode, and it is more to occupy the interior space.

(3) great majority are not with heat supply water and the function of having a bath, and do not satisfy the growing in this respect needs of people.

(4) be not with baking oven.

The purpose of this utility model is will provide a kind of can overcome above deficiency, and is cheap, of many uses, the multi-purpose coal stove of novel self-wind type that the general user can buy.

The purpose of this utility model is achieved in that

One, make meal: adopt following three measures to make the efficient of meal with raising:

(1) installs upper and lower exhausting tube respectively additional in the upper and lower of burner hearth to quicken burning of coal speed; (2) in the tile outer rim, be close to tile and place the secondary air road with the distinguished and admirable speed of preheating acceleration secondary, coal gas can be shifted to an earlier date and fully burning; (3) above fire door, put a stone or metal plate for standing a stove on as a precaution against fire,, improve exothermal efficiency to prolong the time of contact in the flame and the bottom of a pan with curve profile of tooth.

Two, heating: between tile outer sleeve and insulating layer of furnace body, put into a heat exchanger with long garden cylindricality double-jacket, flue outlet is descended as far as possible, adopt and aspirate receiving method, make the flow through surfaces externally and internally of heat exchanger of coal gas of high temperature from top to bottom, with the air heat in the heat exchanger of flowing through and be input to indoor.

Three, have a bath: place a water tank with the preheating water for bathing at the upper periphery place of fire door.Be close to the fire door place above place a ring heater to improve the temperature of water for bathing, thereby guarantee the water temperature and the water yield, this ring heater also can use the snakelike heater shown in the accompanying drawing (4) to replace, and this moment, coll(-tube) heater should be contained in the gap between (9) and (6).

Four, cooking food: fire door is added iron covering, with behind the covering on the water tank on fire door the baking space of a square sealing, food is put on wherein the double-edged fine-toothed comb, utilize from the bell and the infrared ray cooking food of emitting on every side thereof.

The utility model is owing to adopt from exhausting and quicken burning of coal speed and adopt directly to add the heating of hot-air method, thereby has thermal efficiency height, and size is little, and cost is low and be convenient to organize advantage such as a large amount of productions.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Accompanying drawing (1) is the details of the concrete device of the utility model.

Accompanying drawing (2) is the combustion chamber sectional view.

Accompanying drawing (3) is the ring heater of the water temperature of having a bath in order to raising.

Accompanying drawing (4) is in order to the have a bath coll(-tube) heater of water temperature of raising.

Accompanying drawing (5) is a kind of example according to the designed concrete device of the utility model.

Numbering (1) shown in the accompanying drawing (1) is a furnace bottom, and (2) are the stove tube, and exhausting tube (4) down is equipped with in the top that lower clapboard (3), (3) are housed above furnace bottom, and (4) have the big down little truncated cone platform shape of.(4) upper end and tile pallet (8) link.Tile outer sleeve (9) is housed (8).In the central authorities of (9) tile (13) is housed, in the outer rim of (13), be close to tile several secondary ventilating ductings (11) are housed.(11) be to be formed by the bending of rectangle sheet metal, have leg-of-mutton cross section, its shape is just like equal leg angle.Two subchannels (11) and tile are supported on the fire bars (32) together, and fire bars is two sheet metals with rectangular cross section that stand up, and its top has the edge of a knife.Gap location between whole tile and the tile outer sleeve has been full of insulation material (10).The fire door place is placed with annular heat water heater (15) above tile, the annular garden cylindricality that is shaped as hollow of (15).Blade (15-2) is arranged on its upper and lower surface.Toroidal cavity is separated by dividing plate (15-1), on the left and right both sides of (15-1) water inlet pipe (25) is housed respectively and outlet pipe (31) is seen accompanying drawing (3).In the top of heater (15) upper spacer (16) is housed, bell (18) is equipped with in porose, the hole in (16) central authorities.(16) the curve tooth that distributing on stone or metal plate for standing a stove on as a precaution against fire (17), (17) is equipped with in top.Above upper spacer, be peripherally equipped with water tank (19-1) at stone or metal plate for standing a stove on as a precaution against fire.(19-1) the lower left water inlet pipe (25) that has water pipe to pass through valve (26) and annular heating links.When valve (26) can be emitted hot water from valve (27) when closing.(27) place takes back in the top that is contained in (26).The end that the air inlet pipe (29) of running water and three-way valve (30), (30) are housed on the upper side of water tank communicates with water tank, the outlet pipe (31) of one end and ring heater (15) links, can directly deliver to the shower nozzle of bathroom by (31) from the hot water of (15), also can directly get back to water tank (19-1), to the heating that circulates of the water in the water tank.(19-1) meet with outer intermarginal formation narrow of pot and have the effect of quickening the hot gas flow velocity, so (19-1) also be called the exhausting tube.When opening bell (18), put pot or kettle after, open the fire door (24) that is loaded on stove tube bottom, fuel is quickened and through fully heat release of stone or metal plate for standing a stove on as a precaution against fire (17) under the effect of exhausting tube up and down.Thereby improve the furnace temperature and the thermal efficiency, save the meal time of doing.In the accompanying drawing (1), label (6) is elongated cylindrical double-jacket formula heat exchanger, it is made up of inside and outside two drums of closed at both ends, (6) be installed on gap between tile outer sleeve (9) and the insulating layer of furnace body (33), and and (9) and heat-insulation layer between all keep certain clearance.(6) have two fresh air inlets on the lower end side, one communicates with micro-blower (23), and another hole communicates with heating air door (5).(6) upper end has the hole and communicates with hot blast adapter (14).(14) be associated with hot blast backwind tube (7) on, air door (34) is equipped with in the end of (14).Air door (12) is housed (7), (7) and with furnace bottom (1), stove tube (2), upper spacer (3) is formed has grey thorax to communicate.When taking out out heating air door (5) or starting miniature air blast phase (23), the air in flow through (6) promptly is heated and takes over (14) output by hot blast.When needs quicken the speed of getting angry or need further to strengthen firepower, fire door (24) and air door (34) can be closed, (12) are opened, make hot blast enter burner hearth through (12), (7).
