specific Embodiment 1

[0086] The container 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 heating 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

[0088] The container body of the surface-treated kettle 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 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.

[0089] In summary, in the liquid heating container provided by the present invention, since the ratio of the thermal conductivity λ of the coating to the heating power density ρ of the bottom plate of the container body is within 0.2 (m.K) / cm 2 ~150(m.K) / cm 2 In between, the heat conduction effect of the coating and its temperature rise rate are improved, so that on the basis of ensurin...

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, the coating heat conduction coefficient is [lambda], and the container body base plate heating power density is [rho]. The ratio between coating heat conduction coefficient [lambda] and the container body base plate heating power density [rho] is between 0.2(m.K) / sq. cm and 150(m.K) / sq. cm, thus improving the coating heat conduction effect and temperature rise rate, and greatly improving the product heating efficiency.

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, but most of these electric kettle inner tanks or heating bottom plates are polished stainless steel, and basically there is a problem of loud noise during the water heating process; It has greatly affected people's daily life and work, and brought 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 container, comprising: a container body, the container body has an accommodati...
