Description

Family cooking and warming dual-purpose stove

The utility model relates to a family daily heating and cooking stove.

At present, the domestic boilers on the market are generally direct-fired structures, that is, the flame and flue gas burned by coal in the furnace directly enter the chimney. This kind of household stove has insufficient combustion, low thermal efficiency, and serious smoke pollution. In the prior art, there is also a reverse combustion type domestic boiler, which has a reverse combustion chamber composed of a plurality of reverse combustion pipes and flues, and has a very complicated structure.

The purpose of the utility model is to provide a dual-purpose stove for cooking and heating for the family, which not only has the advantages of simple structure and high thermal efficiency, but also saves coal and less pollution.

The utility model is achieved through the following technical solutions. The utility model relates to a dual-purpose stove for cooking and heating in a family, which is mainly composed of a combustion chamber, a flue, a circulating water layer, a furnace mouth, and a slag storage chamber. The combustion chamber is divided into two parts, the first combustion chamber and the second combustion chamber. The first combustion chamber is located above the grate and coal, and a hemispherical steel wall is arranged above it. In the combustion chamber, an annular burner is arranged in the middle, and a hot air circle connected with it is arranged on the periphery of the burner, and the hot air circle is connected with the secondary air inlet pipe. Combustion-supporting holes are opened on the annular inner and outer walls of the burner. The circulating water layer is to connect the inner water tank placed on the inner wall of the combustion chamber with the outer water tank placed on the outer wall of the furnace shell, and connect with the water inlet pipe and the water outlet pipe so that cold water flows in from the water inlet pipe at the bottom of the furnace. The inner water tank, the outer water tank, and the hot water after absorbing heat enter the circulating water channel of the heating pipeline through the outlet pipe. The flue is arranged between the inner and outer water tanks, and its flue gas outlet is connected to the chimney from the lower part of the first combustion chamber. In this way, the flue gas produced by the first and second combustion chambers is not directly discharged from the furnace mouth, but returned to the flue between the inner and outer water tanks, and then discharged into the chimney through the flue gas outlet at the lower part of the furnace body.

The utility model has the following advantages and effects:

1. Since the burner and the hot air ring are installed in the second combustion chamber, the incomplete combustion gas (black smoke) produced in the first combustion chamber gets fresh air and continues to burn to form completely burned white smoke, which is passed through the burner The combustion-supporting hole gathers the flame, conducts heat directly with the cooker and the water tank, and improves the thermal efficiency.

2. Since the flue adopts the structure of direct combustion and reverse combustion, the flue gas returns from the top of the furnace, which not only makes full use of the waste heat of the flue gas to supply the water tank, but also purifies the flue gas, reducing the pollution to the environment.

3. Since the first combustion chamber is equipped with a hemispherical steel inner wall, the water in the inner water tank absorbs heat quickly by utilizing the characteristics of fast heat conduction of the steel plate, which improves the temperature and thermal efficiency of the heating water.

In a word, compared with the prior art, the utility model has the advantages of simple structure, high thermal efficiency, coal saving and less pollution.

The following will be further described through the embodiments in conjunction with the accompanying drawings.

Fig. 1 is a structural front view of a household cooking and warming stove;

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

Fig. 3 is A-A sectional view of Fig. 2;

Fig. 4 is a partial sectional view along line B-B of Fig. 2 .

As shown in Figures 1, 2, and 3, a dual-purpose stove for cooking and heating in a family includes: a combustion chamber, a flue, a circulating water layer, and a furnace mouth and a slag storage chamber. Its combustion chamber is made up of the first combustion chamber 1 above the furnace bar 15 and the second combustion chamber 2 above the first combustion chamber separated by a hemispherical steel wall 14 . The middle part of the second combustion chamber is provided with an annular burner 10, and the periphery of the burner is provided with a hot air ring 9. Combustion-supporting hole 16 is arranged. Its circulating water layer communicates with the inner water tank 3 placed on the inner wall of the combustion chamber and the outer water tank 4 placed in the outer wall of the furnace shell, and communicates with the water inlet pipe 7 and the water outlet pipe 8 . Its flue 5 is arranged between the inner and outer water tanks, and the flue gas outlet 17 (referring to FIG. 4 ) enters the chimney 6 from the bottom of the first combustion chamber 1 . The hot air ring 9 and the annular burner 10 are fixed on the inner wall by a bracket 18 . Outlet pipe 8 is connected in chimney 6, and slag storage chamber 12 is positioned at the below of fire bar 15, and fire mouth 11 is identical with general domestic stove, can make multi-layer fire mouth to adapt to the use of different cooking utensils.

Working process of the present utility model:

After the fuel is ignited in the first combustion chamber, the flame and smoke generated rise up and quickly transfer heat to the water tank through the hemispherical steel wall. After the flue gas enters the second combustion chamber, it forms a mixed gas with oxygen-increased combustion in the burner with the fresh air from the secondary air inlet pipe, and the flame ejected from the combustion-supporting small hole is concentrated on the cooker, which improves the thermal efficiency and shortens the cooking time. Time to boil water and cook. The flue gas is not discharged directly, but returns from top to bottom into the flue between the inner and outer water tanks, and finally is discharged into the chimney from the flue gas outlet at the bottom of the furnace.
