Problems solved by technology

[0003] The current kitchen appliance materials can already meet the basic requirements of electrical appliances for materials. However, the current technology is difficult to meet the increasingly strong requirements of users for easy cleaning.
Range hoods, stoves, microwave ovens and other household appliances commonly used in the kitchen have long-term and high-frequency contact with oil fumes, acid-base substances, and various seasonings, resulting in oil stains on the outer surface and inner tank. Most of the materials in contact are metal materials or metal materials with powder spraying treatment on the surface. The surface energy of these materials is relatively large, resulting in a strong adhesion between oil and materials, and it is difficult to remove oil from the surface of kitchen appliances. It is a pain point for consumers to use kitchen appliances for a long time.
[0004] At present, the users of kitchen appliances mainly adopt the method of cleaning such oil stains by using strong alkaline cleaners combined with hard cleaning products such as steel wool, and cleaning under the action of a relatively large cleaning force. To a certain extent, it can clean the material surface of kitchen appliances, but the strong alkalinity and the large scratching force during cleaning often cause scratches and corrosion on the surface of the material, which affects the appearance of the product and even affects the performance. It brings permanent and irreparable damage to the product; moreover, this traditional method is difficult to clean, takes a long time, and cannot meet the user's convenience and easy cleaning requirements
