People in northern rural areas sleep on kangs to keep warm. Is this good for their health?

People in the south prefer beds, while people in the north prefer kangs." Fired kangs are a heating and sleeping facility invented by northern residents to adapt to the cold climate. Today, although in big cities in the north, kangs have long been used It has been replaced by heating, but it has a broad market in self-built houses in rural areas and is widely loved by people!

But it is an old antique after all. How can it occupy a position among today's various heating methods? What about the hot kang? Today I will tell you about its benefits that make people flock to it!

1. Advantages of the hot kang

1. The heat preservation effect of the hot kang is very good. , is the main means of heating in Northeastern folk houses. The hot bed makes people drowsy as soon as they lie down, and it is extremely comfortable to sleep on. It is an excellent way to treat insomnia, especially for those who have never slept in a hot bed. You can never imagine that feeling, just look at the expression on the dog’s face!

2. It is an inheritance of traditional etiquette! When guests come to a house in the Northeast, they always leave them on the hot bed. If you are an elder, the position at the head of the kang is etiquette, respect, and filial piety!

3. It can cure diseases! Lying on the kang can promote blood circulation and prevent and relieve the pain of rheumatism and arthritis. It may even be cured after long-term use!

4. It can keep your body healthy. The heated kang in the Northeast is spacious and not as narrow as the current beds. You can do somersaults and do yoga without restraint. It is not only beneficial to the health of adults, but also beneficial to children. Children play to avoid catching colds

2. The structure of the heated kang

Before the popularity of red bricks, the heated kang was mostly made of adobe, and was usually connected to a stove, and the stove was used to boil water. The heat used for cooking is used to heat the heated kang. But the disadvantage of this method is - what if you don't need to boil water for cooking but need heating... So this type of heated kang is quite rare at present.

< p>In terms of materials, the current hot kang has basically eliminated adobe and is made of cement board and red brick.

In terms of form, the current hot kang is derived from the stove kang, but it has begun to become an independent heating system. !

3. The Principle of the Fired Kang

To put it simply, the principle of the Fired Kang is to use the heat generated by burning wood or coal to heat the surface of the Fired Kang, and then reduce the temperature of the smoke. It is discharged from the chimney through the flue.

The fire kang is composed of the kang surface and the flue. The structure of the flue is several lines, which will form what the Northeastern people call the kang head and the smoke. The entrance is the kang head, at the end of one kang road, and the exit at the beginning of the other kang road is the kang tip, which is the place where the smoke comes out. It is slightly cooler than the kang head. The smoke enters the kang road from the kang head and passes through the fire channel and flue. It is passed to the panel and finally discharged to the outside through the chimney.

In the layout of the fire kang, the position of the fire mouth is very important. In the traditional stove with the kang, the stove hearth is the fire mouth. After the stove disappears, the layout of the stove mouth becomes free. A lot. It can be placed indoors or outdoors, and the indoor fire outlet can be used as a separate small compartment. But where is the best place to place the fire vent?

▲Indoor fire outlet

The advantage of placing the fire vent indoors is that it is easy to operate. You don’t have to brave the cold wind to go outside to add firewood. There is a heat source in the house, and more heat is radiated indoors. But the disadvantage is that the outside of the fire port is easily blackened, which affects the appearance, and there is also the risk of smoke and dust pouring into the room. It is also unhygienic to remove the fire ashes. More importantly, fuel combustion will consume indoor oxygen and release carbon dioxide and carbon monoxide, posing a risk of gas poisoning! Therefore, no matter from the perspective of hygiene or safety, it is not suitable to place the fire outlet indoors.

If you make an independent fire compartment indoors, this compartment is equivalent to replacing the stove. But inevitably, there will be a lot of heat loss in this compartment, and it's not good either.

▲Indoor independent fire outlet

If you place the fire outlet outdoors, although you have to walk a few more steps when adding firewood, both safety and hygiene can be fully guaranteed. It can be said to be the best choice! At present, in actual use, this fire outlet arrangement method is also the mainstream.

4. New type of heated kang - hanging kang

The panel height of heated kang is generally between 50cm~60cm.

In traditional fire pits, the flue is directly connected to the ground. This not only increases the space that the hot air needs to heat, but also absorbs a large amount of heat from the ground and leads it underground, which wastes energy.

The new generation of fire kang, the hanging kang, uses red bricks and cement boards to create an overhead layer, which isolates the contact between the flue and the ground. It avoids heat being absorbed by the ground and reduces the heating space, which greatly improves the utilization rate of heat. It can be said to be an energy-saving structure.
