Description

Domestic cooking stove with double hearth

technical field

The utility model belongs to the improvement of household cooking and heating stoves, in particular to a household cooking and heating stove with double hearths.

Background technique

At present, most of the domestic cooking and heating furnaces used by urban and rural residents usually have water-jacketed furnace walls on the four walls of the furnace body, and the flue at the back and upper part of the combustion chamber leads to the water-cooled chimney, and the water-cooled chimney is connected to the water-jacketed furnace wall. . The cooking stove can not only be used for cooking, but also the hot water in the heated water jacket furnace wall can be used for heating, bathing and other domestic water. Its shortcoming is that in order to meet the needs of indoor heating in winter, the furnace of the cooking furnace must be designed to be relatively large. In the furnace, there is a sufficient amount of coal burning to heat the water in the water jacket of the cooking furnace, so that the temperature of the heated hot water and The amount of hot water meets the requirements of indoor heating. But use this cooker to cook and supply domestic water in the non-heating season, then the hearth of cooker is bigger, consumes more fuel, causes the waste of energy. In addition, the thermal efficiency of the cooking stove is not high enough.

Contents of the invention

The purpose of this utility model is to provide a household cooking and heating stove with double hearths, which can not only ensure the needs of domestic water for cooking and heating and bathing in winter, but also save fuel and ensure domestic water for cooking and bathing in non-heating seasons. needs. In addition, the utility model has high thermal efficiency and is convenient to use.

The purpose of this utility model is achieved in this way: a domestic cooking and heating furnace with double hearths includes a fire hearth with a water-cooled furnace wall, a grate is installed at the bottom, and an ash bucket is installed in the ventilation room below the furnace wall. The flue in the upper part leads to the water-cooled chimney, the auxiliary furnace is set on one side of the main furnace, the furnace doors are respectively set on the side walls of the main furnace and the auxiliary furnace, and the water jacket furnace walls on both sides of the main furnace are respectively facing the furnace. U-shaped water pipes protrude from the inside, and the pyrotechnic pipes leading to the water jacket chimney are evenly distributed in the flue water jacket at the rear of the main furnace, and a vertical flat water jacket is arranged on the upper part of the water jacket chimney. The water jacket of the chimney is connected, and the smoke outlet at the rear upper part of the auxiliary furnace leads to the flue with the water jacket and is discharged through the outlet.

The utility model uses the main furnace in the heating period. Because the main furnace has sufficient capacity, the fuel is burned for cooking, and the hot water in the heated water jacket furnace wall can ensure the needs of heating and domestic water. Use auxiliary firebox in non-heating season, its firebox capacity is less, and the fuel combustion is used for cooking and the hot water in the heated water jacket furnace wall can be used for domestic water such as bathing. Different seasons like this, use corresponding firebox according to need, just can save fuel in non-heating season.

U-shaped water pipes protrude into the furnace on the water jacket furnace walls on both sides of the main furnace of the utility model, which increases the heat exchange area of the water jacket furnace wall, so that the water in the water jacket can fully communicate with the heat emitted by the furnace fuel. Heat exchange improves thermal efficiency. Pyrotechnic tubes are uniformly arranged in the flue water jacket, so that the waste heat of pyrotechnics in the pyrotechnic tubes is further absorbed by the water in the smoke water jacket. A vertical flat water jacket is arranged on the upper part of the water jacket chimney, which not only enables the water in the water jacket to absorb the waste heat in the flue gas, but also has little resistance to the flue gas flowing in the chimney.

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings. As shown in Fig. 1, Fig. 2 and Fig. 3, a domestic cooking and heating stove with double furnaces includes a furnace with a water inlet water-cooled furnace wall. The grate, the ash bucket is installed in the ventilation room below the grate, the flue at the upper part of the furnace leads to the water-cooled chimney with a water outlet, the auxiliary furnace 1 is set on the side of the main furnace 3, and the main furnace 3 and the auxiliary furnace Furnace doors 20 and 21 are respectively arranged on the side walls of the furnace 1, and U-shaped water pipes 4 are evenly distributed into the furnace on the water jacket furnace walls 2 on both sides of the main furnace 3, and the number of U-shaped water pipes 4 is 4- 8. The pyrotechnic pipes 5 leading to the water jacket chimney 13 are evenly distributed in the flue water jacket 6 at the rear of the main furnace 3, and a vertical flat water jacket 12 is arranged on the top of the water jacket chimney 13, and the flat water jacket 12 is connected to the water jacket chimney. The chimney water jacket 11 communicates, and a rotatable valve plate 9 is installed in the smoke outlet of the water-cooled chimney 13 . Rotate the valve stem by hand to adjust the opening of the valve plate 9 on the smoke exhaust port to control the combustion rate of the fuel in the furnace.
