Rural cooking bench hearth

Abstract

The invention discloses a rural cooking bench hearth. The rural cooking bench hearth comprises a body and a water tank; the water tank is arranged on the outer wall of the body, the body is a trapezoid cylindrical body and is sequentially provided with a furnace ring cover, a top foundation bed, a heat absorbing layer, a fire grate, an ash bucket and a base from top to bottom, the heat absorbing layer and the water tank communicate, the heat absorbing layer is in a net shape, a hot flow channel is formed in the middle of the net-shaped heat absorbing layer, combustion flames pass through the hot flow channel to the top foundation bed, the water tank is provided with a water inlet and a water outlet, the water inlet communicates with a water source, and the water outlet communicates with awater device. According to the rural cooking bench hearth, heat of the high-temperature combustion airflow can be absorbed through the heat absorbing layer, the temperature of the hearth wall face canbe absorbed, the water temperature heating speed in the water tank can be ensured, through the preset hot flow channel, the normal cooker heating needs can be ensured, the heat absorbing layer can reduce the combustion airflow combustion temperature, generation of incoagulability gas like nitric oxide is reduced, and pollution of discharge smoke is reduced.

Problems solved by technology

[0002] At present, most rural areas do not have central heating measures. In the cold winter, coal or straw and branches are generally used for winter heating. These combustion methods are backward, with poor heating effect, low combustion efficiency, waste of resources, and environmental pollution. bigger

Although the country has introduced policy subsidies such as "coal to gas" in some areas in recent years, the heating cost is high, and the subsidies cannot be implemented for a long time. Even many areas have experienced gas shortages and other phenomena, which cannot be fully covered in a short time , so the problem of heating in winter is still very serious

[0003] The hearth used in the existing rural stoves is relatively single, generally only used for heating the stove, and the hearth is generally filled with various unprocessed biomass fuels such as straw, branches, wood chips, etc. The design of the hearth of ordinary stoves is relatively Simple, these fuels are not fully combusted, resulting in an increase in particulate matter and nitrogen and sulfur oxides in the exhaust smoke, and a great waste of fuel

[0004] In winter, people use a large amount of hot water in their lives. Hot water is needed for cleaning kitchen utensils, washing vegetables, and daily washing. These hot water are mostly provided by electric kettles or water heaters, which waste a lot of electric energy.

In recent years, some studies have used the heat source generated by the stove in rural areas to supply domestic water, but most of them use the exhaust heat of the stove, or wrap water pipes around the outer wall of the furnace, and the water pipes absorb the temperature of the wall of the furnace. way, the heat transfer efficiency is relatively low, it cannot meet the daily water consumption, and it will also affect the normal combustion of the boiler stove
