The heat storage pit comprises a pit body, ranges and a chimney, wherein the pit body is positioned underground and comprises a pit plate and a grait heat storage bed; a flue is arranged between the pit plate and the grait heat storage bed; the chimney is vertical to the pit plate; the flue is communicated with the chimney; each range comprises a hearth and a dust falling chamber under the hearth, and a grate is arranged between the hearth and the dust falling chamber; the ranges are a winter range and a summer range; a hot water ring is arranged at the upper part in the hearth of the winter range; the two ends of the hot water ring are communicated with one end of a water supply pipe and one end of a water return pipe; the other ends of the water supply pipe and the water return pipe are communicated with a heating radiator; a smoke outlet of the hearth of the winter range is communicated with a smoke outlet cylinder; a smoke outlet of the smoke outlet cylinder is arranged in the chimney; a sleeve is arranged outside the smoke outlet cylinder in a sleeving manner; a hot air chamber is hermetically formed between the smoke outlet cylinder and the sleeve; one end of the hot air chamber is communicated with a blast pipe and a speed-regulating blast blower; and the other end of the hot air chamber is communicated with a hot air outlet pipe.

Description

technical field [0001] The invention belongs to the technical field of indoor heating facilities, and in particular relates to a heat storage kang which is warm in winter and cool in summer. Background technique [0002] The kang has a long history and rich cultural heritage, and is one of the earliest life heating methods mastered and used by working people in northern my country for a long time under severe cold climate conditions. The kang has a low cost and uses renewable biomass energy. It has certain ecological connotations and rich technical experience. It is in line with the concept of sustainable development and in line with the national energy conservation and emission reduction policies. [0003] The heated kang is also called "kang" or "big kang". brick Stone structure building facilities. The kang is composed of a kang board and a kang wall. There is a flue in the kang wall, which is covered with a concrete kang board, and the top of the kang board is covered ...

AI Technical Summary

Problems solved by technology

[0006] 1. The consumption of firewood is large, fuel is wasted, and the thermal efficiency needs to be improved

[0007] 2. The heat storage effect of the kang body is poor. The kang is intermittently heated. Due to the long intermittent time at night, the indoor temperature in the early morning of severe winter is very low, even lower than 5°C

[0008] 3. Due to the high outdoor temperature in summer, or the low outdoor air pressure in rainy days, if the heat pressure in the chimney and kang body is too small, or in the case of outdoor headwind (the wind direction is opposite to the smoke flow direction), when the wind pressure and heat pressure are opposite When it is used, the stove will not burn well, causing the flue gas to flow back and causing indoor air pollution.

[0009] 4. In summer, the indoor temperature is too high due to the heating of the kang body due to cooking.

The ash chamber of the traditional stove is below the ground, and the grate is flush with the ground. After the fuel is burned, heat pressure is generated, and oxygen cannot enter from the ash chamber. Therefore, the air intake of the stove is almost completely entered from the stove door, while the biomass fuel is added. The stove itself also blocks the air intake, so the combustion lacks oxygen and cannot achieve full combustion

[0012] 2. The height difference between the kang and the stove is too small, and the smoke flow is not smooth

2) After the volatile matter is gradually precipitated and burnt out, the remainder of the fuel is loose coke, and the airflow movement will wrap a part of the carbon particles into the flue to reduce the combustion rate

3) After the volatile matter is burned out, the coke combustion is affected by the ash wrapping and the difficulty of air penetration, which hinders the coke combustion and causes residual carbon in the ash

[0019] At present, the existing floor kang is convenient for people to enter and discharge materials into the fuel pool. The depth of the fuel pool is generally more than 1.5m, so the construction cost of building the fuel pool is increased; at the same time, the area of ​​the fuel pool is generally limited, and the amount of fuel used is quite large. , and it needs to be processed into powder, so the cost of fuel usage is increased; in addition, the feeding and discharging of the fuel pool is laborious and labor-intensive, and the workload is large; The sealing effect of the board and the flue part is not good, which will pollute the indoor air and cause carbon monoxide poisoning
