Description

A kind of multipurpose household oven

The utility model relates to a kind of multipurpose household oven, specifically, relates to a kind of coal gas adverse current reflection combusting multipurpose furnace.

The multipurpose household oven of prior art, the intensification thermal source of its water tank water, how from the diffusing waste heat of furnace outer wall, water tank has only its inwall to be heated, and can not make the water of water tank reach boiling point.Through a heaven-made meal, preheating, the water of its water tank only can be had a bath warming, the indoor ideal temperature that do not reach for a people every night; Moreover, the at present building of building, the most of no heating installation corollary equipment of one-storey house, 1., the boiler of coal gas is seriously polluted the person of having also has its fraud place:; 2., fuel oil (gas) boiler cost is higher.And do not have a heater unit person: 1., warming is little with the electric heater heat; 2., big with two air-conditioning power consumption.

The purpose of this utility model is to overcome the deficiency and the shortcoming of multipurpose household oven in the prior art, but the front yard multipurpose furnace that a kind of heat supply, boiling water, steam, hot blast is provided, cooks.

The purpose of this utility model can adopt following measure to realize:

The utility model is made up of bell, body of heater shell, water tank, burner hearth, flue, grate, fire door, stove leg, delivery port, chimney, secondary water tank, water inlet, flue door; Be provided with exhaust gases passes between tank outer wall and the furnace shell inwall; The lower port of chimney is positioned at the lower end of body of heater, and is connected with exhaust gases passes in the stove; The burner hearth top is provided with Accumulated Heat Units.

Uniform eight flues in the middle of the water tank in the utility model, the two ends up and down and the water tank upper and lower shell of described pipeline are become one; Two secondary water tanks are installed in chimney, and are connected with water tank; Described Accumulated Heat Units is the dome shape, and end face is provided with a central through hole and around eight uniform through holes of centre bore, circle is evenly equipped with eight through holes on the side.

Water tank in the utility model is made by the material of good heat conductivity, and the body of heater shell is made by the good material of heat-insulating property.

Operation principle of the present utility model, be to utilize stack draught to take a hint by pipeline with causing the principle that hot-blast stove (bag) air intake burns again under the coal gas from blast furnace furnace roof coal gas, the coal gas chimney of multipurpose household oven is displaced downwardly to the lower end of stove, draws stock gas counter flow combustion water tank.

Do not doing the time marquis of meal, sealing furnace roof loam cake and chimney shoot door (can stay certain interval air intake combustion-supporting), like this, because the draft effect of chimney, just can make the coal gas (flame) of burner hearth upper end, compel it and reflex to the chimney top, tank inner wall, centre (pipeline), outer wall and secondary water tank all are heated, and reach boiling point very soon (the water temperature situation regulation and control as required of the fire door of burner hearth lower end) by pipeline in the middle of the water tank and the gap adverse current between tank outer wall and the furnace shell inwall.When making meal, fire door and chimney lower end shoot door are opened, bell is also opened, coal in the burner hearth is by the aperture secondary air in fire door air intake, the flue with by pipeline three air intakes of aperture around Accumulated Heat Units in the middle of crack, the water tank between the chimney shoot door process tank outer wall, make coal be able to abundant burning, shorten the meal time of doing.

Advantage of the present utility model is:

1, owing to adopt adverse current reflection and three air intakes (advancing oxygen) technology, make coal be able to abundant burning, carbon monoxide content greatly reduces, and the thermal efficiency obviously improves;

2, can have a bath for the people continuously at any time;

3, speed up as meal.People's family more than three mouthfuls, the past a meal need be with a big honeycomb briquet (every 1 kilogram), and uses cellulor coal (every 0.5 kilogram) to get final product now, economizes on coal 50%;

4, family's heating in winter.Not only available hot-water heating, steam heating, but also available hot blast.Particularly use hot blast, can save fin, send hot blast to indoor (every chamber connects an air outlet) by pipeline and get final product.It is indoor to send hot blast also outdoor ozone can be delivered to through preheating, makes indoor continuous oxygenation denitrification, improves people's the general level of the health.

5, volume is little, and is in light weight, durable in use.

The drawing of accompanying drawing is described as follows:

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

Fig. 2 is that the A-A of Fig. 1 is to cutaway view;

Fig. 3 is the cutaway view of the utility model Accumulated Heat Units;

Fig. 4 is the vertical view of Fig. 3;

Fig. 5 is that the B-B of Fig. 4 is to cutaway view;

The utility model is done with detailed description below with reference to embodiment (accompanying drawing):

As shown in Figure 1, the utility model is made up of bell (1), body of heater shell (3), water tank (4), burner hearth (5), flue (6), grate (8), fire door (9), stove leg (10), delivery port (11), chimney (12), secondary water tank (13), water inlet (14), flue door (15); The lower port of chimney (12) directly connects the lower end with stove, and communicates with the interior exhaust gases passes that pokes up the fire, but does not communicate with burner hearth (5); Space between water tank (4) outer wall and the furnace shell inwall is an exhaust gases passes; Burner hearth (5) top is provided with Accumulated Heat Units (2).Accumulated Heat Units (12) is dome-shaped, and a central through hole is arranged end face and around eight uniform small through hole of centre bore, circle is evenly equipped with eight through holes on the side.Uniform eight flues (7) in the middle of the water tank (4), described flue (7) is become one with water tank (4) upper and lower shell.Two secondary water tanks (13) are installed in chimney (12), and are connected with water tank (4).At flue (6) eight secondary airs (oxygen) aperture is arranged on every side, it is combustion-supporting to advance hot blast; Water tank (4) by heat conductivility preferably material make, as aluminium alloy, can forge iron etc.; Body of heater shell (3) by heat-insulating property preferably material make, also available thin wall iron, in add insulation material.

The utility model can be made three kinds on large, medium and small type, both can burn the smokeless coal that looses, and also can burn honeycomb briquette, and the life-span is more than 20 years.
