A kind of multi-fuel and multifunctional civil stove

Abstract

The invention relates to a multi-fuel multi-function civil stove. The multi-fuel multi-function civil stove comprises a stove body, a water heating part and tiles, wherein the water heating part is assembled on the stove body, and the tiles are sleeved in the stove body; the tiles are internally provided with grates, the upper part of the stove body is provided with a stove platform, the bottom of the stove platform is connected with the top parts of the tiles and a joint of the stove platform and the tiles is provided with a stove port, the upper surface of the stove platform is provided with a stove port and a chimney, and the lower part of the stove body is provided with a base and a dust outlet; the multi-fuel multi-function civil stove is characterized by comprising secondary air inlet channels which are arranged on the outer sides of the tiles and are of longitudinal groove structures, wherein gaps are formed among the secondary air inlet channels and the inner side walls of the stove body, the upper parts of the tiles are also provided with multiple through holes which are utilized as secondary air inlet holes, secondary air inlets are arranged on a position, which is opposite to the secondary air inlet channels, on the lower part of the stove body, and air can enter from the secondary air inlets and rises along the secondary air inlet channels so as to enter into the stove body from the secondary air inlet. The multi-fuel multi-function civil stove provided by the invention has the beneficial effects that the structure is simple, the multi-fuel multi-function civil stove is suitable for multiple fuels, the production cost is low, and the multi-fuel multi-function civil stove has a cooking function, heating function, a warming function, a domestic hot water function and the like.

Description

technical field [0001] The invention relates to the field of civil stoves, in particular to a multi-fuel and multifunctional civil stove. Background technique [0002] my country's civil stove industry started in the 1970s. With social progress and the improvement of economic and living conditions, civil stoves have gradually replaced the stacked stoves that have been used for thousands of years due to their advantages of convenience, sanitation, high efficiency, and quickness. replace. The furnace body of civil stoves is welded by steel plates or cast with pig iron, and then equipped with refractory furnace tiles, grates, water-absorbing jackets, furnace covers and other components, which are assembled, sprayed and decorated. , forest branches, crop stalks, weeds, cow dung, biomass solid briquette fuel and other raw materials can provide people with a variety of living energy such as cooking, heating, rain, domestic hot water, and baking. Civil stoves are beautiful, practi...

Problems solved by technology

[0004] (1) The product has strict requirements on fuel, and it cannot be used for a variety of fuels: due to the differences in the chemical composition of different fuels, their combustion characteristics are also different, which leads to the structural design of the burner (stove) depending on the fuel Therefore, the civilian stoves currently on the market can only be used for a specific or similar fuel, that is: coal-fired stoves can only burn coal, biomass stoves can only burn biomass, and the fuel cannot be used universally; As far as the structural design of existing stoves is concerned, if fuels are mixed, there will be defects such as inconvenient use, reduced combustion efficiency, increased pollutant emissions, and unsatisfactory use effects such as cooking and heating;

[0005] (2) The product has a single function, which is difficult to meet people's existing living needs: With the improvement of people's living conditions, people have more and more requirements for the use of stoves, and the functions of civilian stoves on the market currently include: There are three types of cooking type, heating type, and cooking heating type. Only a few products have the functions of shower hot water and kang heating. During the heating season, people use heating type or cooking heating type; during non-heating season, people use cooking type; The structural design of cooking and heating stoves can only be used in the heating season and cannot be used in non-heating seasons; in northern China, a family must purchase two stoves for use in different seasons, which is cumbersome and increases cost;

[0006] (3) The product structure design is unscientific and the manufacturing process is complicated: the existing stove products usually adopt the following design in the combustion secondary oxygen supply structure: first, the position of the secondary air inlet is set around or above the furnace mouth; It uses cast iron, steel pipe and other materials to manufacture the air induction pipe and inlet hole. The existing structural design has disadvantages such as complex manufacturing process, high cost, and poor oxygen supply effect.
