The heating element of an electric cooker includes an electric heating tube type heating plate and a P.T.C. element heating plate. The electric heating tube type heating plate has good insulation, corrosion resistance, thermal conductivity, and mechanical strength, long service life, and high efficiency; P. The T.C. element heating plate has the characteristics of positive temperature resistance coefficient and automatic temperature control, high efficiency, and no open flame,
Less affected by power fluctuations.
The temperature control components of an electric rice cooker include a bimetallic sheet temperature control system and a magnetic material temperature control system, but the former is not as safe and reliable as the latter. Electric rice cookers are divided into combination and integral types according to the structural form of the pot body; According to the pressure inside the pot during use, it is divided into low pressure (0.04MPa), medium pressure (0.1MPa), and high pressure (0.15-0.2MPa); According to the way food is heated, it can be divided into direct heating and indirect heating.
Since the 1950s, electric rice cookers have become popular. In 1986, the production of electric rice cookers in the United States was 5.9 million, while in Japan it was 6.92 million. In 1987, the production of electric rice cookers in China reached 10.2632 million. In the mid-1980s, electronic rice cookers equipped with microprocessors began to be launched on the market (firepower, temperature, time, heating mode, etc.).
