The Development Course of Kitchen

1. Looking at the evolution of kitchen pattern in the history of China, on the one hand, it depends on the development of productivity, on the other hand, it also depends on the local natural conditions and living habits of residents. The kitchen has roughly experienced the following development periods. After the evolution of different periods, the functionality of the kitchen gradually tends to be reasonable.

2. Live around the fireplace. About 6000-7000 years ago, China entered the clan society. With the change of people's labor tools and skills, people slowly developed from caves to semi-caves, and finally moved to the ground. From the excavated house ruins, it can be found that people set up a fire pit (ground stove) in the center of the house built on the ground at that time. The fire pool is usually located in the center of the house or far away from the door. The flame in the fire pool will not go out all year round, so it can be used at any time. You can sit and move easily. After a day's work or when the weather is too bad to work, the fireplace becomes the center of family activities. Those stories handed down from generation to generation, accompanied by the smoke in the fire pond, maintain the reproduction and civilization of a nation. There are charcoal blocks and animal bones in the pit, and there is a smoke outlet on the roof. This arrangement has many functions, such as cooking, heating, dehumidification and animal prevention. However, because it is not isolated from the whole room, smoke permeates the whole room and the sanitary conditions are very poor. Due to traditional customs and regional characteristics, some ethnic minority houses still have fire pits. For example, yurts and bamboo buildings in the southwest.

3. A house with a stove in the corner. With the development of production and the change of lifestyle, people's material life is gradually enriched, and their diet has changed from barbecue to cooking. At this time, the construction technology is becoming more and more perfect, which objectively creates conditions for improving the folk houses in Huotang. In order to solve the problem of smoke exhaust and convenient operation, the stove gradually moved from the center of the room to the corner. The fireplace has also been improved and changed into a brick stove. The pot rack stands on the stove and is equipped with a chimney built along the wall, which is more sanitary, safe and tidy. Cooking also plays a role in heating, such as kang stoves in the north, brick stoves in the south, coal stoves and briquette stoves in urban houses, but in essence this kitchen still belongs to other spaces, and the interference with other spaces has not been completely solved.
