Description

Dope layer structure for household electrical appliances

Technical Field

The utility model relates to a coating field for household electrical appliances, more specifically say, it relates to a dope layer structure for household electrical appliances.

Background

A water boiling kettle is a container for boiling water. Most of the existing kettles are made of stainless steel.

The paint is a material composed of film forming matter, filler (pigment and filler), solvent and assistant. The components of the coating may sometimes vary slightly depending on the performance requirements, e.g., the varnish may be free of pigments and fillers, and the powder coating may be free of solvents.

Generally applied to the surface of an article for protecting or decorating the article, for example, to coat the outer wall of a kettle with a coating for partial thermal insulation and aesthetic appearance. However, when the water in the existing kettle is boiled, the kettle wall of the kettle can be very hot even if the thermal insulation coating exists on the kettle wall, so people can generally place the kettle for a period of time and pour out the boiled water in the kettle after cooling.

And placed a period of time after at the kettle, the temperature in the kettle can't be judged through the vision to people, if trade with the hand to touch the kettle wall then easily scalded, if continuously wait then the temperature can continuously reduce, people may drink the water that the temperature is lower than normal.
