Embodiment 1

[0039] Such as figure 1 As shown, the electric kettle in this embodiment includes a kettle body 80 , an electric heating chassis 90 disposed at the bottom of the kettle body 80 , and a power base (not shown) connected to the electric heating chassis 90 and providing power thereto.

[0040] Such as figure 2 As shown, the electric heating chassis 90 includes a heat transfer substrate 10 on which a heating element is disposed, and the heating element includes two power supply connection terminals. The heat transfer substrate 10 is provided with an insulating and heat-conducting coating 11, and the heating element is a heat-generating sheet 20 made of an electrothermal alloy arranged on the insulating and heat-conducting coating 11, and the chassis also includes a heat-generating sheet 20 for pressing the heat-emitting sheet 20. A fixed structure 30 fixed on the insulating and thermally conductive coating 11.

[0041] Electrothermal alloy material is an alloy material used to m...

Embodiment 2

[0052] Only the differences between this embodiment and Embodiment 1 are described here: the fixing structure of this embodiment includes a flexible insulating sheet and a fixed tray, the flexible insulating sheet is pressed on the heating sheet, and the fixed tray is fixed to the heat transfer substrate Connect to press-fit the heating sheet on the insulating and heat-conducting coating, and the middle part of the flexible insulating sheet and the fixing tray are provided with through holes, and these through holes constitute the power connection holes of the fixed structure.

[0053] In addition, the heat transfer substrate in this embodiment is a heated panel arranged at the bottom of the kettle body, the heated panel is fixedly connected with the bottom of the kettle body, and an insulating and heat-conductive coating is coated on the heated panel. That is, the heat transfer substrate is not a part of the kettle body, and after being heated, the heat transfer substrate need...

Abstract

The invention relates to a liquid heating device, in particular to an electric heating chassis and an electric heating kettle. The electric heating chassis comprises a heat transfer substrate, wherein a heating element is arranged on the heat transfer substrate, the heating element comprises a first power supply connecting end and a second power supply connecting end, an insulation heat conduction coating is arranged on the heat transfer substrate, and the heating element is a heating sheet made of an electric heating alloy and arranged on the insulation heat conduction coating. The electric heating chassis also comprises a fixing structure used for pressing and fixing the heating sheet on the insulation heat conduction coating. The heating sheet can be obtained by punching and cutting an electric heating sheet, the manufacture cost of the heating sheet is lower than that of a thick-film heating sheet manufactured by using a high-price special device through screen printing; meanwhile, the heating has excellent properties of high heating speed, uniform heating, simple structure, less occupation space and the like similar to those of the thick-film heating sheet. The electric heating kettle comprises a kettle body and the electric heating chassis arranged on the bottom of the kettle body.

Description

technical field [0001] The invention relates to a liquid heating device, in particular to an electric heating chassis and an electric kettle. Background technique [0002] At present, electric kettles often use the chassis heating method. As far as the chassis heating structure is concerned, there are usually the following two structural forms: [0003] (1) Heat pipe chassis. The chassis of this structure includes a metal disk surface, and heat pipes are arranged on the metal disk surface. The heat of the heating pipe is transferred to the bottom of the kettle body through the metal plate to heat the liquid. The heating tube is in the shape of a ring as a whole, and a heating wire is wrapped in an aluminum shell. The structure of the heat pipe seems to be simple, but in fact the process is quite complicated. A typical heat pipe manufacturing process includes more than 40 processes. In the manufacturing process, not only consumes a lot of energy, but also produces a variet...
