Electric heating components are widely used in home appliances, ranging from refrigerators, air conditioners, electric water heaters and washing machines to electric kettles, rice cookers, soymilk machines and curling irons, all of which require electric heating components. Therefore, the technical changes of electric heating components are closely related to most home appliances.

Electric heating components for small appliances:

Electric heating film is expected to be marketed

Small appliances are an important application area for electric heating components. Most small appliances such as electric kettles, irons, and electric ovens mainly use electric heating pipes; curlers, hair straighteners, etc. use PTC components; heaters, bath tyres, and some heater products Use far infrared carbon fiber electric heating tube.

According to industry insiders, the current domestic electric component companies supporting small appliances include Ningbo Senna Electric Appliance Co., Ltd., Jiangsu Shundian Thermal Material Co., Ltd. and Zhongshan Jinlun Hardware Products Co., Ltd.

Lu Jiji, China Sales Manager of Sirix Electric Co., Ltd. introduced that although electric heating components only account for 10% to 20% of the cost of small appliances, they determine the quality and reliability of small appliances. Therefore, at present, more and more enterprises hope to purchase reliable quality electric heating components, and "the concentration of electric heating component enterprises supporting small appliances is getting higher and higher."

According to "Electrical Appliance" reporters, the technical development of the market for electric appliances for small appliances is relatively stable, and traditional electric appliances still occupy the mainstream of the market. In recent years, only a few new technology products have appeared, such as electric heating films.

"As early as 2004, Philips introduced an electric kettle with an electric heating film. But it didn't take long for this product to have quality problems, and the cost was high, and it was out of the market after a while." Lu Jiji said.

Ningbo Senna Electric Heating Appliance Co., Ltd. Zhang Guoqing said that although the degree of marketization of electric heating film is not high, but electric component companies are actively developing and trial marketing, hoping that products can enter the market as soon as possible. "In recent years, through trial marketing, we have found some shortcomings in the product, but these problems can be solved. I believe that the electrothermal film can be marketed in the future."

According to "Electrical Appliance" reporters, in the field of electric kettles, there are mainly two types of heating elements: tube and pan. In recent years, sales of disc-type electric heating components have been increasing. Jiang Zhiping of Jiangsu Shundian Thermal Materials Co., Ltd. said that at present, the market for electric kettles is 70%, and only 30% for tubes. Although the cost of disc-type electric heating components is higher, because of its beautiful appearance and more popular with consumers, the market share will further increase in the future.

At the same time, some electric heating components used in the field of emerging home appliances have also become hotspots for various enterprises. For example, Hangzhou Hehe Electric Co., Ltd. has achieved mass production of electric heating components for soymilk machines with automatic fuse function this year; in 2009, it invested 5 million yuan for the technological transformation of stainless steel electric heating cup electric components and the construction of production lines. Also achieved great results in 2010. Zhang Guoqing said: "This year, we have formed a production capacity of 150,000 sets of electric heating components for stainless steel electric heating cups, and the product has been in short supply."

Regarding the application of PTC as an electric heating component in small appliances, industry insiders believe that in recent years, the PTC market for heaters is shrinking.
