1. The initial stage (before 1980): The product structure is simple and the function is single. Before the 1980s, the development of China's gas industry was still relatively backward. The popularity of city gas was very low, only 10%. Almost no one in the vast rural areas uses gas. At that time, the gas stove was in its infancy (before 1980), and its product structure was simple and its function was single.
Previously, each of the gas appliances had the simplest gas stove, and the product structure was simple. Most of the cooktop materials are cast iron, surface plating or spraying, and there is no electric ignition device, and the process is also in a relatively primitive state.
2. Development stage (1980-1990): greatly improved durability and reliability
After 1980, with the deepening of reform and opening up, the market economy has risen. Various foreign gas appliances have entered China, and the number of gas appliance manufacturers has soared from nearly 10 to nearly 100. It has also evolved from a single gas company to a state-owned, collective, private and other business types. Foreign famous gas appliance manufacturers have also begun to find partners in China, thus making the quality and appearance of gas appliances.
There have also been fundamental changes, and the variety and function of the products are constantly changing.
During this time, panels, combustion systems, and ignitions have also been improved. The panel material is cold plate sprayed, the burner has a cast iron burner, surface plating or zinc spray treatment, and the ignition device adopts piezoelectric electronic ignition to improve the ignition rate, and the durability and reliability of the gas stove are improved.
3. Breakthrough stage (1990-2006): The variety is increased and the styles are complete.
After the 1990s, China and the world economy entered a stage of rapid development. China's gas and gas appliance business has entered a period of rapid growth. The introduction of foreign advanced burning appliance development and manufacturing technology has brought about a breakthrough change in China's burning appliance business.
Household gas cookers have increased varieties, novel styles, enhanced safety measures, and improved materials, functions and performance. Improvements in production quality and reliability, process level, automation and intelligence, advancement of performance indicators, energy conservation and environmental protection, and safe use have also been made.
The material of the cooker basically eliminated the cast iron. Stainless steel panels, surface-coated non-stick oil coating materials, tempered glass panels, etc. occupy an important position in the cooker, and ceramic panels in recent years are also unique.
