Problems solved by technology

[0002] At present, electric heating devices for liquids are attracting more and more people's attention, and there are endless kettles on the market. However, most of these electric kettle inner tanks or heating bottom plates are polished stainless steel, and there are basically problems of loud noise during the heating process, and The greater the power of the kettle, the greater the noise it produces; this greatly affects people's daily life and work, and brings great inconvenience to consumers

specific Embodiment 1

[0094] The surface-treated kettle liner has a fluorine-containing coating. The thermal conductivity of the coating is 0.35W / (m K), the coating thickness is 20μm, the hardness is 3H, and the contact angle with the coating is 103°. The kettle is heated The power is 1500W, and the heating power density is 12W / cm 2 , When the kettle is boiling water normally, the maximum temperature on the surface of the heating plate is 105°C, and the maximum noise during the boiling process of the kettle is 51dB, while the noise of the kettle without surface treatment is 62dB, which has a good noise reduction effect.

specific Embodiment 2

[0096] The surface-treated kettle liner has a ceramic coating. The thermal conductivity of the coating is 1.0W / (m K), the coating thickness is 30μm, the hardness is 6H, and the contact angle with the coating is 108°. The heating power of the kettle is 1800W, heating power density is 15W / cm 2 , When the kettle is boiling water normally, the maximum temperature on the surface of the heating plate is 110°C, and the maximum noise during the boiling process of the kettle is 52dB, while the noise of the kettle without surface treatment is 62dB, which has a good noise reduction effect.

[0097] To sum up, in the liquid heating container provided by the present invention, a coating is formed on the inner wall of the container body. The coating is flat when viewed directly, but has a microscopic concave-convex structure, which is easy to form gasification cores on the coating. The gasification core grows to form bubbles, and when the bubbles grow to an appropriate size, they leave the ...

Abstract

The invention provides a liquid heating container comprising a container body, a heating assembly and a coating; the container body has a contain cavity used for containing liquid; the heating assembly is used for heating up the liquid in the contain cavity; the coating is formed on the inner wall of the container body, and the coating thickness d is 5-50 micron. The liquid heating container arranges the coating on the inner wall of the container body; the coating is flat when directly observed, yet has accidented structures in a microscopic scope, thus easily forming gasification cores on the coating; the gasification core grows to form a bubble, and the bubble grows in a proper size and breaks away from the coating, thus greatly reducing heater noises in a water boiling process, bringing conveniences for people daily life and works, improving consumer usage comfort level, and greatly increasing product market competitiveness.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a liquid heating container. Background technique [0002] At present, electric heating devices for liquids are attracting more and more people's attention, and there are endless kettles on the market. However, most of these electric kettle inner tanks or heating bottom plates are polished stainless steel, and there are basically problems of loud noise during the heating process, and The greater the power of the kettle, the greater the noise it produces; this greatly affects people's daily life and work, and brings great inconvenience to consumers. Contents of the invention [0003] In order to solve at least one of the above technical problems, the purpose of the present invention is to provide a liquid heating container with better noise reduction effect. [0004] In order to achieve the above object, an embodiment of the present invention provides a liquid heating contain...
