The importance of research on energy efficiency of electric heating elements for household appliances：
With the popularity of smart home appliances, the society's requirements for electrical energy efficiency have reached a higher level. The electric heating element is the core component of energy conversion in many electrical appliances, and it is also the main energy consumption component in the whole electrical appliance. Its energy consumption and actual utilization rate directly affect the whole machine, and it is the core of energy efficiency.
Different from the energy efficiency assessment of the whole machine, the actual energy efficiency of parts is greatly affected by the design and installation process of the whole machine. The high energy efficiency of the parts does not mean that the whole machine can obtain a higher energy efficiency level.
However, the components such as electric heating elements, which are widely used and have large power consumption base, can save huge amounts of energy and reduce carbon emissions for the production and life of the whole society if their energy efficiency is slightly improved. Therefore, it is of great social and practical value to conduct systematic research on the energy efficiency of electric heating elements and formulate certain assessment standards.
