specific Embodiment 1

[0117] The body of the surface-treated kettle has a fluorine-containing coating, the thermal conductivity of the coating is 0.35W / (m·K), the thickness of the coating is 20μm, the hardness is 3H, and the contact angle with the coating is 103° , The kettle heating power is 1500W, and the heating power density is 12W / cm 2 , The maximum temperature of the heating plate surface when the kettle is boiling normally is 105℃, the maximum noise during the kettle boiling process is 51dB, and the noise of the kettle without surface treatment is 62dB, which has a good noise reduction effect.

specific Embodiment 2

[0119] The container body of the surface-treated kettle has a ceramic coating, the thermal conductivity of the coating is 1.0W / (m·K), the thickness of the coating is 30μm, the hardness is 6H, the contact angle with the coating is 108°, the heating power of the kettle 1800W, heating power density is 15W / cm 2 , The maximum temperature of the heating plate surface when the kettle is boiling normally is 110°C, the maximum noise during the kettle boiling process is 52dB, and the noise of the kettle without surface treatment is 62dB, which has a good noise reduction effect.

[0120] To sum up, in the liquid heating container provided by the present invention, the thermal conductivity of the coating on the inner wall of the container body is 0.2W / (m·K)~10W / (m·K), which avoids that the thermal conductivity is too small, causing the coating The layer affects the efficiency of the liquid heating vessel, and at the same time prevents the phenomenon that the thermal conductivity is too large ...

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 heat conduction coefficient is 0.2W / (m.K)-10W / (m.K). 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, liquid electric heating devices are getting more and more attention, and there are endless kettles on the market. However, the inner tank or heating bottom of these electric kettles are mostly stainless steel polished, and there is basically a problem of loud noise during the boiling process; this It affects people's daily life and work to a large extent, and brings great inconvenience to consumers. Summary of the invention [0003] In order to solve at least one of the above-mentioned technical problems, the object 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 container, including a container body, the container body has a containing cavity for cont...
