Description

Household cooking and heating dual-purpose stove

technical field

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

Background technique

There are many types of known household furnaces to meet the needs of different occasions, and many furnace structures have been formed. For dual-purpose stoves for heating and cooking, in order to integrate cooking and heating, a "multi-purpose boiler" with a circulating water chamber in the furnace body and more water pipes for heat exchange is often used. The structure is unreasonable, the fuel cannot be fully burned, which not only reduces the thermal efficiency, wastes energy, but also pollutes the environment with the exhausted smoke; some use more water pipes for heat exchange, not only the structure is complicated, the price is high, Moreover, water pipes are prone to fouling, difficult to clean, and troublesome to operate.

Contents of the invention

The purpose of the utility model is to overcome the shortcomings of the prior art and provide a dual-purpose stove for cooking and heating for household use, which has the advantages of reasonable and simple structure, low price, convenient use, energy saving and environmental protection.

The purpose of this utility model is achieved in that a dual-purpose stove for household cooking and heating includes: a furnace body, a furnace surface, a combustion chamber on the upper part of the hearth, a flue communicated with the combustion chamber, and a circulating water jacket. The combustion chamber is divided into a primary combustion chamber and a secondary combustion chamber. The primary combustion chamber is surrounded by a refractory cement furnace wall, and above the refractory cement furnace wall is a conical inner furnace. There is an adjustable secondary air inlet on the furnace body, a combustion-supporting vent on the furnace fire port, a secondary combustion chamber above the furnace fire port, and a circulating hot water jacket on the periphery of the combustion chamber. The flue is in the shape of an "S". It communicates with the secondary combustion chamber and reaches the bottom of the furnace body, and then returns upward to the exhaust port. There is a circulating water pipe in the channel.

The furnace surface is provided with a movable thermal insulation cover, and the movable thermal insulation cover is equipped with refractory fiber, which is connected with the furnace surface by a hinge and is equipped with a bracket.

The "S" shaped flue is provided with a dust collection box at the port at the bottom of the furnace.

The upper part of the "S" shaped flue is provided with a water inlet pipe and a hot water outlet.

The hot water jacket is connected with a pressure relief port.

Compared with the prior art, the utility model is provided with a conical inner furnace in the combustion chamber, an adjustable secondary air inlet is provided on the furnace body outside the inner furnace, and a combustion-supporting vent is provided on the furnace fire port. Therefore, when the secondary cold air enters the furnace, it will absorb a large amount of heat from the inner furnace, which can not only reduce the temperature of the inner furnace, prevent it from being oxidized, and play a protective role, but also recover heat energy and increase the temperature of the air. , so that the hot air is mixed with the incompletely burned gas at the crater to achieve secondary combustion. It not only saves energy, but also improves thermal efficiency, and at the same time, makes exhaust gas meet environmental protection requirements. Since the flue and the surrounding circulating hot water jacket are designed in an "S" shape, the flue gas moves in an "S" shape from top to bottom, and then from bottom to top, and the pyrotechnic stroke is lengthened. The heat exchange improves the thermal efficiency, and after the flue gas is turned down, the smoke and dust fall into the dust collection basin by its own weight, which reduces the dust emission and is beneficial to environmental protection. Because the movable insulation cover is set on the stove top, it is hingedly connected with the stove top, and a support is housed. When not cooking, use it to cover the fire ring, which can keep warm without wasting heat. When cooking, the heat preservation cover can be opened through the hinge, and supported by the support on it, which increases the cooking work surface and facilitates the use.

In summary, compared with the prior art, the utility model has the advantages of reasonable design, high thermal efficiency, simple structure, low price, convenient use, energy saving, and environmental protection.

The utility model will be further described through the embodiments below in conjunction with the accompanying drawings.
