Abstract

The utility model which relates to a family furnace used for cooking and heating consists of a burning chamber, a flue, a water circulating layer, a furnace mouth and a residue storage chamber. The burning chamber consists of a first burning chamber and a second burning chamber; a ring-shaped burning device and a thermal blast ring are arranged in the second burning chamber; the water circulating layer is formed by communicating an internal water box of the inner wall of the burning chamber with an outer water box which is arranged in the furnace shell, and connecting internal water box of the inner wall of the burning chamber with a water inlet pipe and a water outlet pipe; the flue is arranged between the internal and the external water box, and the flue gases outlet is connected into a chimney through the first burning chamber. The utility model has the advantages of simple structure, high heat efficiency, coal-saving and small pollution.

Description

Family cooks a meal, heating dual-purpose stove

The utility model relates to the daily heating of family, kitchener.

At present, the domestic boiler on the market is generally direct-fired structure, and promptly coal-fired flame, flue gas in the burner hearth internal combustion directly enter chimney.This domestic burners burning is insufficient, and the thermal efficiency is low, and smoke contamination is serious.A kind of counter-burning type domestic boiler is also arranged in the prior art, and it is by the anti-burning chamber that a plurality of anti-burning pipes and flue are formed, and structure is very complicated.

The purpose of this utility model is the shortcoming at prior art, provides that a kind of family cooks a meal, heating dual-purpose stove, not only has advantage simple in structure, that the thermal efficiency is high, and economizes coal, of low pollution.

The utility model is achieved through the following technical solutions.A kind of family cooks a meal, heating dual-purpose stove, mainly is made of combustion chamber, flue, circulation water layer and fire door and dreg chamber.Described combustion chamber is divided into first combustion chamber and second combustion chamber two parts, first combustion chamber be positioned at fire bars, coal-fired above, its top is provided with hemispherical steel wall, be second combustion chamber above the hemispherical steel wall, its middle part is provided with annular burner, the periphery of burner is provided with the hot blast circle that is communicated with it, and hot blast circle and secondary wind inleting tube join.Have combustion-supporting hole on the annular inside and outside wall of burner.Described circulation water layer, be to place the inner water tank of combustion chamber inwall and place the outer water tank in the furnace shell outer wall to be communicated with, and join with water inlet pipe and outlet pipe, make it to form water inlet pipe inflow inner water tank, the outer water tank of cold water by the stove bottom, the hot water after the heat absorption is entered the circulating water channel of heating pipeline by outlet pipe.Between the outer water tank, its exhanst gas outlet inserted chimney by the bottom of first combustion chamber in described flue was arranged on.The flue gas that first and second combustion chamber is produced is not directly discharged by fire door, but the flue between the outer water tank in being fed back into, the exhanst gas outlet by the body of heater bottom enters chimney again.

The utlity model has following advantage and effect:

1, owing in second combustion chamber, is provided with burner and hot blast circle, the unburnt gas (black smoke) that the combustion chamber of winning is produced has obtained fresh air, burn away, form the white cigarette of completing combustion, flame has been gathered in combustion-supporting hole through burner, with cooker, the direct heat conduction of water tank, improved the thermal efficiency.

2, because flue is taked the anti-sintering structure of direct combustion, and flue gas is returned by furnace roof, the waste heat that has not only made full use of flue gas is supplied with water tank, and flue gas obtained purification, has reduced the pollution to environment.

3, because first combustion chamber is provided with hemispherical steel inwall, utilize the fast characteristic of steel plate heat conduction, made the very fast heat absorption of water of inner water tank, improved the temperature and the thermal efficiency of heating water.

In a word, the utility model compared with prior art, and is simple in structure, the thermal efficiency is high, saving is coal-fired, pollution is few.

Below by embodiment, further be illustrated in conjunction with the accompanying drawings.

Fig. 1 is for a kind of family cooks a meal, the structural front view of heating dual-purpose stove;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the A-A cutaway view of Fig. 2;

Fig. 4 is the B-B partial sectional view of Fig. 2.

As shown in Figure 1, 2, 3, a kind of family cooks a meal, heating dual-purpose stove, comprising: combustion chamber, flue, circulation water layer and fire door and dreg chamber.Its combustion chamber is by first combustion chamber 1 of fire bars 15 tops and be positioned at above first combustion chamber, form through second combustion chamber 2 that hemispherical steel wall 14 is separated.The middle part of second combustion chamber is provided with annular burner 10, and the burner periphery is provided with hot blast circle 9, and burner is communicated with the hot blast circle, and hot blast circle and secondary wind inleting tube 13 join, and has combustion-supporting hole 16 on the inside and outside wall of annular burner 10.Its circulation water layer is to place the inner water tank 3 of combustion chamber inwall and to place the outer water tank 4 in the furnace shell outer wall to be communicated with, and communicates with water inlet pipe 7 and outlet pipe 8.Between the outer water tank, exhanst gas outlet 17 (referring to Fig. 4) entered chimney 6 by the bottom of first combustion chamber 1 in its flue 5 was arranged on.Hot blast circle 9 and annular burner 10 are fixed on the inwall by support 18.Outlet pipe 8 is by picking out in the chimney 6, and dreg chamber 12 is positioned at the below of fire bars 15, and fire door 11 is identical with general domestic burners, can make the use that the multilayer fire door adapts to different cookers.

The course of work of the present utility model:

After fuel was lighted in first combustion chamber, the flame of generation, flue gas rose, and by the hemispherical steel wall feed-tank that conducts heat rapidly.After flue gas entered second combustion chamber, the fresh air that feeds with secondary wind inleting tube formed mist oxygenation burning in burner, and the flame that is sprayed by combustion-supporting aperture concentrates on the cooker, has improved the thermal efficiency, the time that having shortened heats up water cooks.Flue gas is not directly discharged, but the flue between the outer water tank in returning from top to bottom, the exhanst gas outlet by the stove bottom enters chimney at last.
