(1) development status of global household appliance drainage pump industry

Drain pumps for household appliances are the core components of household appliances such as washing machines and dishwashers. They mainly include three types of products: general drainage pumps, special drainage pumps and condensation pumps. Its quality stability and energy saving efficiency are important guarantees for the overall quality and energy saving of products such as washing machines and dishwashers. Mainly used in drum washing machines, dishwashers, agitated washing machines, condensing clothes dryers and some pulsator washing machines. In addition, with the increase in consumption levels, more and more washing machine designs need to be equipped with two drainage pumps to achieve the function of circulating water and drainage respectively.

At present, the drainage pumps for household appliances are mainly permanent magnet drainage pumps, which are mainly used in drum washing machines, dishwashers, stirring washing machines, condensing clothes dryers and some pulsator washing machines. The permanent magnet drainage pumps produced by the company are mainly divided into three types: general drainage pumps, special drainage pumps and condensation pumps.

After going through the early stage of the shaded-pole drainage pump, the drainage pumps for household appliances around the world are mainly permanent magnet drainage pumps. Foreign companies realized the mass production and sales of permanent magnet motor drainage pumps in the early 1990s. Their main markets are concentrated in washing machines and dishwashers, and they have been widely used in aquarium equipment and small ornamental products. Compared with shaded pole drainage pumps, permanent magnet motor drainage pumps have many advantages such as long life, small energy consumption, small size, wide range of adaptable voltage, and stable head flow. At present, the world's major manufacturers of drainage pumps include Italy ASKOLL, Dier Hanyu, Germany HANNING, Spain CORECCI, etc. All of the above companies have applied for or owned patents for product startup structures in major industrial countries, and provided permanent magnet motor drainage pump components to white goods companies worldwide.

In the future, as the requirements for energy saving and noise reduction of household appliances increase, the "Brushless DC Drain Pump" developed by Dier Hanyu will likely rely on its advantages in intelligence and conversion efficiency to gradually become the future drainage with the "Permanent Magnet Drain Pump" The main product of the pump market.

In addition, in the past, the drainage pumps of household appliances used copper enameled wire as the coil windings. However, due to the fluctuation of international copper prices, the rise in copper prices has put a lot of pressure on the cost of production enterprises. After years of R & D and multi-party verification, Dier Hanyu took the lead in using aluminum enameled wire instead of copper enameled wire in the drainage pumps of home appliances. Large-scale applications. If copper prices continue to run high in the future, aluminum enameled wire drainage pumps will likely become more advantageous drainage pump products.

According to a study by the Chamber of Commerce for Mechanical and Electrical Industry, the total global sales volume of home appliance drainage pumps in 2010 was approximately 10 million units, a year-on-year increase of approximately 6% and a compound growth rate of approximately 3% from 2006 to 2010. In 2010, the global sales of home appliance drainage pumps exceeded US $ 350 million, a year-on-year increase of approximately 6.5%, and a compound growth rate of approximately 4% from 2006 to 2010.

(2) development status of domestic household appliance drainage pump industry

In the early days, domestic washing machine manufacturers mostly used shaded pole drainage pumps. Beginning in the 1990s, domestic washing machine manufacturers began to import permanent magnet drain pumps produced by foreign companies. For example, Haier initially used the permanent magnet drain pumps from Emerson in the United States, and Little Swan and Midea used the German permanent magnet drain pumps. Subsequently, domestic household electrical appliance drainage pump manufacturers also began to study foreign companies' advanced permanent magnet drainage pump production technologies, but since early domestic permanent magnet motor drainage pump manufacturers almost did not have technology patents, their development was slow. In recent years, Dier Hanyu has taken the lead in breaking through the permanent magnet drainage pump technology in China, and has obtained a number of patents including the drainage pump starting structure, etc., has realized the localization of permanent magnet drainage pumps, and obtained domestic and foreign washing machines. Manufacturer's approval has led the rapid development of domestic domestic drainage pump industry.

According to a study by the Chamber of Commerce for Mechanical and Electrical Industry, in 2010, the total domestic sales of home appliances drain pumps were approximately 11 million units, a year-on-year increase of approximately 9.5%, and a compound growth rate of approximately 8% from 2006 to 2010. Domestic sales of home appliance drainage pumps exceeded US $ 28 million in 2010, an increase of approximately 10% compared to 2009, and a compound growth rate of approximately 9% from 2006 to 2010.

Against the background of the steady growth in the demand for the international washing machine and dishwasher market, with the rapid increase in the proportion of domestic drum washing machine sales and the increase in demand for domestic dishwashers, the home appliance drainage pump industry will be driven to continue to maintain a stable and rapid development of.
