The temperature difference between anti-freezing fluids of genuine and fake vehicles is very different, and various auto accessories are hard to distinguish. Yesterday, the Urban Quality Supervision Bureau and Chaoyang District Quality Supervision Bureau held the "3·15" campaign to protect auto parts consumers' rights and interests in Dongjiao Auto Parts City.

The heating elements of electric cooker include electric heating tube type heating plate and P.T.C. element heating plate. Electric heating tube type heating plate has good insulation, corrosion resistance, thermal conductivity and mechanical strength, long life and high efficiency; P.T.C. element heating plate has the characteristics of positive temperature resistivity and automatic temperature control, high efficiency, no open flame,
Less affected by power fluctuations.
The temperature control elements of the Rice Cooker include a bimetal temperature control system and a magnetic material temperature control system. The former is not as safe and reliable as the latter. The electric rice cooker is divided into combined type and integral type according to the structure of the pot body; according to the pressure in the pot, it is divided into low pressure type (0.04MPa), medium pressure type (0.1MPa) and high pressure type (0.15~0.2MPa); The methods of heating food are divided into direct heating and indirect heating.
