Description

Multifunctional energy-saving wood stove

technical field

The utility model relates to a civil stove, in particular to a civil wood stove.

Background technique

As we all know, my country is a country with relatively serious shortage of coal and oil resources. In order to save coal and petroleum fuel resources and reduce the cost of living, combined with the characteristics of large rural population and high dispersion in our country, some civilian wood stoves have been developed on the market. It is conducive to the full utilization of waste resources, and the wood stove is small in size, light in weight, convenient and safe to use. Therefore, it is used as a stove for vast rural areas, suburban families and small and medium-sized catering shops and stalls, and it is more and more popular with people. But existing civilian wood stove also has some deficiencies: the one, the thermal efficiency of wood stove combustion is not high enough, can produce more ash and soot when burning, is unfavorable for catering sanitation and environmental protection; Water, also cannot be used for heating. Therefore, there is the problem that the thermal efficiency is not high enough in the existing civil wood stove, and the use function is relatively single.

Utility model content

Aiming at the problem that the thermal efficiency of the civil wood stove in the above-mentioned prior art is not high enough and the use function is relatively single, the utility model proposes a kind of stove that not only has high thermal efficiency and low cost of use, but also can supply hot water and can also be used for heating. And a versatile energy-efficient wood stove with great applicability.

The technical solution adopted for the technical problem to be solved by the utility model is: the multifunctional energy-saving firewood stove includes a hearth, a furnace frame, a water tank and a combustion chamber, and a middle hearth, a small hearth and a furnace cover are movable in sequence on the hearth, The hearth is fixed on the cover plate, the water tank is ring-shaped, and the water tank is welded and sealed by the inner plate, outer plate, bottom plate and cover plate to form a whole, a combustion chamber is set in the middle cavity of the water tank, and a feeding hole is set on the upper part of the water tank , cold water pipe and exhaust pipe, air inlet and hot water pipe are arranged at the lower part of the water tank, a grate is arranged on the bottom surface of the combustion chamber, auxiliary air inlet holes are arranged at the lower part of the side wall of the combustion chamber, and an auxiliary air inlet is arranged on the side wall of the hearth There is a chimney, and an arc-shaped fire baffle is arranged on the bottom surface of the hearth near the side of the chimney.

The utility model makes the inner plate of the water tank close to the outer chamber of the combustion chamber as soon as possible while ensuring that the auxiliary air inlet hole can enter the air.

Since there are a variety of movable stoves and furnace covers on the stovetop, it can be used with pots of different specifications to ensure that the distance between the bottom of different pots and the combustion chamber is in a normal state, and make full use of the combustion heat. It can also be used for heating in winter; because the auxiliary air inlet hole is set on the lower part of the side of the combustion chamber, the wind energy in the combustion chamber can form reflection convection, so that the firewood in the combustion chamber can be burned more fully; There is a fire baffle, and the firewood is reflected after being blocked by the fire baffle, so that the firewood will not be sucked away by the chimney, so that the flame in the hearth can be fully utilized. The utility model has the advantages of compact structure, convenient operation and safe use. Compared with burning coal, the fuel cost can be reduced by more than 50% every day. Water and heating, and can also meet the use of pots of different specifications.
