As we all know, compared with other household appliances, electric door products have higher and stricter requirements for after-sales service. In the past, consumers were often concerned about the energy efficiency of the electric door itself, installation, maintenance and other conventional links, but they lacked basic understanding and understanding of the use and maintenance process of the electric door. In fact, electric doors, like retractable doors, can only be maintained regularly Reduce energy consumption to a certain extent. According to the estimation of 1.5-piece single cooling electric door, its power consumption in one year of normal use is about 900 degrees. According to the technical analysis report, affected by dust, oil and other factors, the annual power consumption of electric door will increase by about 15% after two to three years of use, and the proportion of power consumption increase will be greater when it is used in the environment with large dust and oil. If the professional maintenance of the electric door is carried out regularly, the annual power consumption of the electric door will be reduced by at least 15%, which not only saves the overall energy consumption of the society, but also greatly reduces the household electricity expenditure. It is conservatively estimated that there are more than 150 million electric doors in China. If they can be maintained professionally, they will save at least 20 billion kilowatt hours of electricity a year. This professional maintenance is Midea's "deep cleaning" service for household electric doors, which is launched on the occasion of 315 consumer rights day. "Deep cleaning" is different from ordinary electric door cleaning. It is a comprehensive and thorough cleaning of the core parts of the electric door from the inside to the outside. It is a very professional service and has very high requirements for the technical level of the operators.
